Device for dispensing, in particular for vaporizing volatile substances, in particular fragrances and / or active substances

The invention relates to a device for dispensing, in particular for vaporizing, volatile substances, in particular fragrances and / or active substances, according to the preamble of claim 1. Furthermore, the invention relates to a method for dispensing, in particular for vaporizing, volatile substances, in particular fragrances and / or active substances, according to the preamble of claim 34.

Devices for dispensing, in particular for vaporizing, volatile substances, in particular fragrances and / or active substances, are generally known and as a rule comprise a container in which a substance to be dispensed is received. In the container, a wick is arranged as a capillary element, which projects beyond the container with a free wick end and in such a way is in contact with the substance to be dispensed that it is conveyed by the capillary action of the wick toward the free end of the wick. The free end of the wick is regularly associated with a heating element, in particular an electric heating element, by means of which the free wick end can be subjected to heat in order to release the substances accumulating in the free end of the wick even faster to the environment or to be able to evaporate. Such a structure is known for example from WO 98/58692 A1. In order to adjust the degree of evaporation and thus the evaporation performance, it is further provided in this WO 98/58692 A1 to store the container together with wick so height adjustable in the housing of the device that the relative position of the wick to the heater is variable.

Such a structure is also known in principle from EP 1 108 358 A1. With such a structure, the evaporation rate and thus the discharge rate of the substance to be dispensed over a longer period can be influenced. at However, such devices may have the problem that the generated and enriched with the substance to be dispensed substance air flow, which escapes into the environment via an outlet opening in the housing wall, is influenced by resulting in the interior of the housing air turbulence, on the one hand, the outflow of the Substance air flow is impaired and that, on the other hand, to some extent undesirable deposits and condensations of the substance to be dispensed on the housing inner walls. Furthermore, in such devices, in particular in the case of an arrangement close to the wall, there is the risk that the outflowing substance air stream already transitions into the intrinsically desired unstable convection state just above the device, which allows the substance to be dispensed or spread into the space , However, at relatively low in space, for example, arranged in the wall area at a power outlet devices, this often leads only to an insufficient effectiveness of the distribution of the substance to be dispensed in the room or even unwanted deposits of the substance to be dispensed on the wall.

In contrast, it is an object of the present invention to provide an apparatus and a method for dispensing, in particular for vaporizing, volatile substances, in particular fragrances and / or active substances, by means of which the substance delivery can be made even more effective or the efficiency of the substance delivery can be increased even further.

This object is achieved with the features of the independent claims. Advantageous embodiments thereof are the subject of the dependent claims.

According to claim 1, a device for dispensing, in particular for vaporizing, volatile substances, in particular fragrances and / or active substances, with a housing, a heater and with a, preferably directly or indirectly connectable to the housing, container for the substance to be dispensed proposed, which has a standing in contact with the substance to be dispensed wick as a capillary element having a heater associated with the wick-side substance delivery area. According to the invention, the heating device comprises a first heating area, by means of which by heat emission to the wick-side substance delivery area with a Substance-enriched substance-air flow can be generated. Furthermore, the heating device comprises a second heating region, by means of which a substance-free hot air flow can be generated by heat emission to at least one substance-free air stream to be heated, wherein the at least two air streams are aligned such that they meet, preferably outside the device, and one flowing away from the device Make up substance hot air stream. It should be noted that the two air streams are not allowed to mix or mix at least for a certain time or distance after their meeting. This means that although the two air streams form a "common" substance hot air stream flowing out of the device, this is formed by two substantially "parallel" air streams that do not extend at least for a certain time or distance, as stated above mix. This allows, as will be explained in more detail below, the desired increased effectiveness of the substance delivery.

Further, according to the invention at least one adjusting device is provided, by means of which, in particular for adjusting the temperature of the dochtseitigen substance dispensing area and thus to adjust the amount of substance to be dispensed by the substance amount of air, the heat output of the first heating area to the dochtseitigen substance delivery area is adjustable and by means of the heat output of the second heating region is adjustable to the air flow to be heated, wherein the temperature, in particular the temperature and / or the flow velocity, of the substance-free hot air flow can be adjusted by the heat emission of the second heating region to the air flow to be heated.

The temperature or the flow velocity of the substance-free hot air stream can basically be set or changed by the heat output of the second heating region alone, for example, such that the heating power of the second heating region and thus the heat output of the second heating region increase the temperature or the flow velocity the air flow to be heated is increased. Alternatively or additionally, the temperature or the flow rate of the substance-free hot air flow can also be adjusted or changed by means of the flow and thus the residence time of the substance-free air stream to be heated in the area of the second heating area in the flow path of the air flow to be heated, for example by at least one the flow area varying means, such as a throttle element, to name just one example. Such a device should in particular make it possible, as already mentioned, to increase the residence time of the air stream to be heated in the region of the second heating zone, resulting in an increased temperature output to the air stream to be heated and thus to an elevated temperature and thus again a relatively high flow velocity the substance-free hot air flow leads. In an analogous manner, however, such a device also makes it possible, correspondingly reversed, to lower the residence time of the air stream to be heated in the region of the second heating zone, which then leads to a reduction in the heat output to the air stream to be heated and thus to a reduced temperature and thus flow rate of the substance-free Hot air flow leads.

Preferred embodiments of such a flow cross-section changing device will be explained in more detail below.

By means of the device and method according to the invention can thus or by means of the second heating a warmer compared to the substance air flow or hotter hot air flow is generated, by means of which the substance air flow can be influenced and controlled as the primary air flow so that this substance to the environment on the one hand at a desired height and the other in a desired direction. Another significant advantage of the invention is that it can be ensured in a simple manner, for example, in connection with attachable to walls or wall-mounted sockets devices that the preferred relative to the hot air flow substance air flow reliably kept away from a wall adjacent to the device or can be steered away from this. In particular, this results in a very good, unhindered distribution of the substance in a room.

The term "substance to be dispensed" is to be understood here in a broad sense and encompasses all substances which can be conveyed by means of the capillary action of a wick as a capillary element.This can, in addition to liquid substances, also be expressly gel-like or other suitable substances. Wick "is to be understood here in a comprehensive sense and expressly includes any capillary element capable of promoting a substance by capillary action.

The device and method according to the invention are also characterized in particular by the presence of at least one adjusting device, by means of which both the heat output of the first heating region and the heat output of the second heating region are adjustable and thus adjustable. This can be ensured in a simple manner by means of at least one setting device that the temperature of the dochtseitigen substance delivery area and thus correlated by means of the substance air flow amount of substance is always correlated or correlated with the temperature or the flow rate of the substance-free hot air flow, and preferably in such a way that a defined ratio between the temperature of the wick-side substance delivery area and / or the substance air flow on the one hand and the temperature of the substance-free hot air flow on the other hand is set. As a result, it can be ensured in a simple manner that the temperature or flow rate of the substance-free hot air stream always fits optimally to the temperature of the non-donor substance delivery region and thus to the delivered substance quantity in order to maximize the effectiveness with regard to the release of the substance or its distribution in a room achieve. The inventively provided adjusting device therefore allows a targeted adaptation of the respective heat output of the two heating areas to a specific given or desired situation, such as a desired by a user certain release rate of the substance in a room. The inventive at least one adjusting device thus substantially increases the flexibility of the device and thus their field of application.

The at least one adjusting device can in principle be designed in many different ways, so that the term "adjusting device" is to be understood expressly in a broad sense, and in particular to the effect that these not only purely mechanical or purely mechanically actuated components Components of the device may be formed, for example, by means of manually displaceable components or components of the device is formed (for example, is designed as a hand-operated linear displacement device), but in principle a control and / or regulating device part of at least one Can form an adjustment, by means of the mechanical and / or electrical components or components of the device, for example, to their displacement and / or their power supply, can be controlled and by means of which then, for example, the heat output of the first and / or second heating region and thus Finally, the amount of substance in the substance air flow and / or the temperature of the substance-free hot air flow can be adjusted, changed and / or influenced.

Particularly preferred is a specific embodiment in which the at least one adjusting device is designed so that by means of at least one adjusting the heat output of the second heating to the air stream to be heated and thus the temperature of substance-free Heizluftstroms, preferably in dependence on the means of at least one Setting device by the heat emission of the first heating range set temperature of dochtseitigen substance delivery area and / or substance air flow, is adjustable or adjusted so that the substance-free hot air flow has a higher temperature than the substance-enriched substance air flow and / or that the desired defined The ratio between on the one hand the temperature of the wicking substance delivery area and / or the substance air flow and on the other hand, the temperature of the substance-free hot air flow is set. This setting of a higher temperature of the substance-free hot air flow compared to the substance air flow or in particular the setting of the defined ratio between the temperature of the wicking substance delivery area and / or substance air flow and the temperature of the substance-free hot air flow is thus preferably dependent, that is as Reaction to the set by means of at least one setting device temperature of dochtseitigen substance delivery area and / or substance-air flow, so that this temperature of dochtseitigen substance delivery area and / or substance air flow forms, so to speak, the "reference variable", based on a certain temperature (And thus also the flow velocity) of the substance-free hot air flow is adjusted to the defined ratio between the temperature of dochtseitigen substance delivery area and / or the substance air flow on the one hand and the temperature of the substance-free n Hot air flow on the other hand set to the desired extent. By means of the at least one adjusting device, the heat output to the first and second heating area can basically be set independently of one another, for example in such a way that the heat output of the first heating area is first changed correspondingly with a desired change in the substance output quantity and then in a next step also the heat output by means of the second heating area is adjusted or tracked accordingly. However, this may possibly require an increased tax or standard effort or an increased adjustment effort. According to a particularly preferred embodiment, it is therefore proposed that the at least one adjusting device is designed so that in a caused by means of at least one adjusting device change in the heat output of the first heating area, preferably automatically and / or positively coupled, by means of at least one adjusting the heat dissipation means of the second heating region to the air flow to be heated is variable so that the defined ratio between the temperature of dochtseitigen substance delivery area and / or substance air flow on the one hand and the temperature of the substance-free hot air flow on the other hand is set. This can be done, for example, in such a way that, in the case of a change in the heat output of the first heating area detected by the at least one adjusting device, for example by a detection device of the adjusting device, for example by a corresponding operation by an operator, not only the heat output corresponding to the operator's request to the is changed at the same time by the at least one adjusting device and the heat output of the second heating area to set the desired ratio between the temperature of dochtseitigen substance delivery area and / or substance air flow below the temperature of the substance-free hot air flow. This can for example be done automatically or automatically by means of a control and / or regulating device as part of the at least one adjusting device and / or done by a corresponding mechanical forced coupling, in which, for example, in conjunction with a change in position of a first heating area at the same time with the first heating area positively coupled second heating is shifted with, to name just one example. Furthermore, according to a particularly preferred specific embodiment, it can be provided that the at least one adjusting device is designed in such a way that that the relative position, preferably the distance, between the first heating area and the wicking substance dispensing area is adjustable or changeable by means of the at least one adjusting device, so that the first heating area for adjusting or modifying the heat output to the non-wetting substance dispensing area by means of the at least one adjusting device different positions with respect to the dochtseitigen substance delivery area can be arranged. The following basic principle preferably applies here: The first heating area acts on the nonwoven substance delivery area in a position (first position or near position) in which it is closer to the nonwoven substance delivery area than in a second location with a larger amount of heat which is further away. It goes without saying that, of course, a plurality of intermediate positions can be set between individual positions, in particular between a maximum and a minimum position. As stated above, only the basic principle of the different application of heat quantity at different positions of the first heating area with respect to the nonwoven substance dispensing area will be shown here.

In this connection, it is particularly advantageous if the temperature of the substance-free hot air stream is set by means of the at least one adjusting device such that the substance-free hot air stream has a higher temperature in the first position or near position of the first heating region than in the second position of the first heating region, and Although in such a way that the substance-free hot air flow in the first position of the first heating region has a higher temperature than in the second position of the first heating region and also the defined ratio between the temperature of dochtseitigen substance delivery area and / or substance air flow and the temperature of substance-free Hot air flow is maintained. This ensures that given a higher substance delivery and a higher temperature of the hot air flow is given, which significantly improves the effectiveness of the substance delivery in the room.

Particularly preferred in this case is an embodiment in which by means of the at least one adjusting device, the temperature of the wicking substance delivery area, preferably based on a wick temperature and thus to a temperature of the wicking substance delivery range of 60 ° C to 150 ° C, and the temperature of the substance-free hot air flow is adjustable so that the ratio between the temperature of the wicking side substance delivery region and the temperature of the substance-free hot air flow is 1: 1.5 to 1: 2. That is, it is particularly advantageous if the temperature of the substance-free hot air flow is 1, 5 to 2 times higher than the temperature of the wicking side substance delivery region.

In principle, there are various possibilities for supplying the air stream to be heated to the second heating area. Particularly preferred is an embodiment in which the second heating region is associated with at least a portion of a flow channel, wherein the air to be heated flows into the flow channel and wherein the air heated by means of the second heating air flows out of the flow channel as substance-free hot air flow. Such a flow channel provides defined geometric conditions by means of which the inflow and outflow is just as easy to control, as the heat supply by means of the second heating region.

Furthermore, there are basically different ways to set the temperature of the substance-free hot air flow in the desired manner. Thus, for example, by means of the at least one adjusting device, the heating power of the second heating region and thus the heat output of the second heating region are adjusted to the air flow to be heated, preferably depending on the defined ratio between the temperature of the non-donor substance delivery area and / or substance Air flow and the temperature of the substance-free hot air flow. The temperature of the substance-free hot air flow can thus be adjusted in such a solution by the regulation of the heating power of the second heating region, for example increased or decreased. Alternatively or additionally, however, it can also be provided that the flow cross-section in the region of the flow channel can be adjusted or changed by means of the at least one adjusting device such that the residence time of the air to be heated in the flow channel section assigned to the second heating region and thus ultimately the temperature the substance-free hot air flow, preferably as a function of the defined ratio between the temperature of the wicking substance delivery area and / or Substance air flow and the temperature of the substance-free hot air flow, is adjustable. In this case, it is particularly preferred that the residence time of the air flow to be heated in the flow channel section assigned to the second heating area is greater at a smaller flow cross-section than in the case of a larger flow cross-section.

There are thus various possibilities for adjusting the temperature of the substance-free hot air flow and thus, in particular, for adjusting the ratio between the temperature of the nonwoven substance delivery area and / or substance air flow and the temperature of the substance-free hot air flow:

Thus, with constant or substantially constant heating power of the second, in particular of the first and second, heating region, the temperature of the substance-free hot air flow and thus in particular the above-defined ratio between the temperature of dochtseitigen substance delivery area and / or substance air flow and the temperature the substance-free hot air flow solely by the adjustment of the flow cross-section and thus the residence time in the, the second heating area associated flow channel section can be adjusted.

Alternatively, the temperature of the substance-free hot air stream but also solely by the change in the heating power of the second heating and thus by the heat output of the second heating to the air stream to be heated, that is without the flow cross-section influencing measures are set, and thus in particular the aforementioned ratio between the temperature of the wicking side substance delivery region and / or substance air flow and the temperature of the substance-free hot air flow can be adjusted. As an alternative to this, the temperature of the substance-free hot air stream could in principle also be changed or adjusted by both measures, preferably simultaneously, for example by changing the heating power as well as changing the flow cross-section, for example to obtain a desired temperature of the substance-free hot air stream in FIG With regard to a defined predetermined ratio between the temperature of the non-woven side Substance delivery range and / or substance air flow and the temperature of the substance-free hot air flow adjust.

With reference to the basic principle presented above in connection with the specific embodiment, in which the distance between the first heating region and the non-substance substance delivery region can be changed by means of the at least one adjusting device such that the first heating region converts the non-substance substance delivery region into a first or second substance delivery region. Near-position is applied with a larger amount of heat than in a second position further away, then, for example, in the case that a constant heating power of at least the second heating region is present, at a first heating element arranged in the first position, a smaller flow cross-section released than in a the second position arranged first heating area. As a result, the hot air flow has a higher temperature at a first heating area arranged in the first position than at a heating area arranged in the second position, wherein the design also preferably takes place such that the defined ratio between the temperature of the non-volatile substance dispensing area and / or Substance air flow and the temperature of the substance-free hot air flow is maintained or adjusted.

According to a particularly preferred specific embodiment, it is provided that at least one element which changes the flow cross-section and is adjustable and / or displaceable by means of the at least one adjusting device is arranged in the flow path of the air flow to be heated. By means of such an adjustable or displaceable element in the flow path of the air stream to be heated or in the flow path of the hot air flow results in a simple and flexible adjustment of the flow cross-section.

Further, the flow channel can be a, in particular stationary and / or constituent of the housing forming and / or not part of the movable heater forming, first flow channel section and, the second heating associated with, in particular displaceable and / or component of displaceable heating device forming second flow channel section, which are fluidly coupled or connected to each other in an abutment region and the upon actuation of the at least one adjusting device for Setting or changing the flow cross-section of the flow channel, in particular for adjusting the Überströmquerschnittes between the first flow channel section and the second flow channel section, relative to each other are displaced. By means of such a relative displacement possibility of the flow channel sections, the flow cross section of a flow channel can be set in a particularly simple and functionally reliable manner.

According to a particularly preferred specific embodiment, it can be provided that the heating device has and / or includes the second flow channel section, which is thus assigned to the second heating zone. Alternatively or additionally, in this case, the first and second flow channel sections are assigned to one another such that the second heating zone applies more heat to the air to be heated at a first flow cross-section which is smaller than a second flow cross-section. Here is thus at smaller flow cross sections a longer residence time of the air to be heated in the second heating area associated flow channel section given as compared with larger flow cross sections, thereby correspondingly the temperature of the substance-free hot air flow at the smaller flow cross sections is correspondingly higher than in the larger flow cross sections ,

According to a particularly preferred specific embodiment, a throttle element is arranged in the adjoining region of the two flow channel sections, or a throttle element is formed by means of which the flow cross section of the flow channel can be adjusted or changed, in particular the flow cross section of the flow channel in a relative displacement of the two flow channel sections carried out by means of the at least one adjustment device Overflow cross section from the second flow channel section to the first flow channel section is variable. Such a throttle element in the adjoining region of the two flow channel sections allows easy adjustment of the respective flow cross-section, in particular a Überströmquerschnitts, between the two flow channel sections in the relative displacement. Particularly preferred is an embodiment in which the throttle element in a low position, in particular a low position of the displaceable Heating device, is arranged in the flow channel, that a minimum flow cross-section, in particular a minimum overflow, is released for a high heat load of the air flow to be heated. Next, the throttle element is in a high position, in particular a high position of the displaceable heater arranged in the flow channel, that a maximum flow cross-section, in particular a maximum overflow, is released for a relation to the low position lower heat input of the air stream to be heated. The throttle element may have a arranged in the flow channel and the air flow at least partially flow around throttle body or be formed by one of the two flow channel sections and is located in the adjoining region of the two flow channel sections at a variable distance to an associated flow channel wall portion of the other flow channel section, so at least an overflow duct section is formed between the first flow duct section and the second flow duct section, the flow cross section of which can be changed by the relative displacement of the two flow duct sections.

With such a construction, particularly preferred defined throttle geometries result, for example, such that the throttle body is arranged in the low position, in particular a low position of the displaceable heater, at a distance from the associated flow channel wall region, that the at least one overflow channel section has a minimum flow cross section, in particular one minimal overflow. By contrast, in the high position, in particular a high position of the displaceable heating device, the throttle body can then be arranged at such a distance from the associated flow channel wall region that the at least one overflow channel section has a maximum flow cross section, in particular a maximum overflow cross section.

Next, the throttle body at least partially with a gap distance to a surrounding the throttle body inner wall portion of the throttle body having flow channel portion, preferably the first Flow channel section, be arranged. Characterized is formed between the throttle body and the surrounding inner wall region at least one of the Überströmkanalabschnitt directly or indirectly fluidly connected throttle body Umströmungskanalabschnitt over which the throttle body incoming air flow around the throttle body can be defined to flow to at least one Überströmkanalabschnitt.

According to a further particularly preferred specific embodiment, the throttle body may have a piston-like shape and at least one end and edge arranged oblique surface adjacent to the abutment region, the one at the other flow channel section, an inclined surface with substantially the same slope flow channel wall region assigned to form at least one obliquely extending overflow channel is. The mutually associated inclined surfaces are then here to change the Überströmquerschnitts in a relative displacement between the first flow channel section and the second flow channel section toward or away from each other movable. Such an inclined surface configuration is particularly advantageous in order to avoid turbulence and turbulence in the air stream to be heated.

This is achieved particularly advantageously by a symmetrical configuration in which the throttle body, based on a cross section through the throttle body, two adjacent to the adjoining area, end, left and right side inclined surfaces, those at the other flow channel section, an inclined surface with substantially is associated with the same inclination extending flow channel wall region for forming at least one obliquely extending overflow channel section. The mutually associated inclined surfaces are thereby moved toward one another or away from one another in order to change the overflow cross section in the case of a relative displacement between the first flow channel section and the second flow channel section.

It should be expressly mentioned at this point that the term "inclined surface" does not necessarily mean that it must be rectilinear.Curved inclined surface courses, for example with a convex or a concave curvature, may also be provided. According to a further particularly preferred embodiment, the throttle body, viewed in the flow direction of the air flow to be heated, upstream of the second heating region may be arranged. This ensures in a simple manner that the component of the throttle element influencing the residence time in the flow channel section assigned to the second heating zone is located upstream of this second heating zone.

The heating device itself can be formed by a single heating element, which has or forms both the first and the second heating region, so that the two heating regions can be displaced together or positively coupled when the heating device is displaced by means of the preferably single adjusting device. In such an embodiment, it is then to be ensured that, in the case of a change in position, the particular desired temperatures of the nonwoven substance delivery region or of the hot air stream are / are set in the desired manner, for example by means of thermally insulating measures between the individual heating regions.

The same applies analogously to a preferred alternative embodiment in which the first heating region and the second heating region of the heating device are each formed by a separate and / or spaced-apart heating element. These can in principle be displaced independently of one another by means of the at least one adjusting device, but are preferably arranged on the heating device such that they can be displaced together or positively coupled when the heating device is displaced by means of the preferably single adjusting device.

In connection with an embodiment in which the first heating region and the second heating region are formed by separate heating elements, it is particularly advantageous if the heating device is formed by a separate component, preferably of a plastic material, on which the first heating element and the second Heating element are mounted and which is displaceable relative to the housing at a displacement of the heater by means of, preferably single, adjusting means. However, any other suitable materials may be used instead of a plastic material. The at least one heating element is preferably an electrical heating element. Preferably, this electrical heating element has a radiator made of a thermally conductive material and at least one thermally coupled to the radiator, preferably at least partially integrated in the radiator and / or embedded, electrical resistance element that can be connected to the energy supply to an energy source and / or by means of an energy source electrical energy is supplied. The electrical resistance element may be any suitable resistance element, for example a PTC resistor, to name just one example.

The radiator itself can be made, for example, of a highly thermally conductive ceramic material or even of a highly thermally conductive plastic material, to name just two examples. According to a further particularly preferred specific embodiment, the first heating region may be formed by a heating element, preferably a heating element, with a wick recess or a wick recess into which the wick communicates with the substance delivery area, preferably with a free wick end projecting the container as a substance delivery area , stands. In this case, it is preferably provided that the first heating region can be arranged as a substance delivery region in different positions relative to the wick end projecting from the container when it is displaced by means of the adjusting device in the wick axis longitudinal direction. The wick recess may, for example, also be embodied only as an edge-side recess, into which the wick protrudes with the substance delivery area, preferably with a free wick end projecting beyond the container as the substance delivery area.

According to a further particularly preferred embodiment, the second heating element forming the second heating region, preferably a heating element, has a passage opening, wherein this passage opening forms a flow channel section forming part of the heating device, in particular the second flow channel section. With such a structure, a particularly compact and functionally integrated embodiment is provided, which is also easy to implement in terms of manufacturing technology. In principle, the first heating region can have one, two or even more electrically resistive elements which can be controlled individually or jointly in order to ensure a desired heat output and thus heat dissipation to the nonwoven substance delivery region. The same applies analogously to the second heating region, which may likewise have one, two or more electrical resistance elements which can be controlled individually or jointly. This allows the heating capacity of the heating areas to be set individually and adapted to the respective conditions. According to a further particularly preferred embodiment, at least one flow guiding and / or deflecting device is provided, by means of which the substance-free hot air flow can be conducted and / or deflected such that the two air streams meet, preferably at a defined angle of incidence and / or outside the device form substance-hot air stream flowing out of the device. Such Strömungsleit- and / or deflection allows a simple and reliable way, the desired steering and orientation of the substance-free hot air flow.

According to a further particularly preferred embodiment, the flow channel can have a discharge channel section forming part of the heating device, which, viewed in the direction of flow, preferably connects like a chimney upstream of a flow channel section assigned to the second heating zone and via which the substance-free hot air stream flows. With such a construction, in which the heating device simultaneously also forms the outflow channel section, it is ensured that the device has a compact construction overall. However, such a structure is particularly advantageous in connection with a configuration in which the outflow channel section of the flow channel simultaneously forms the flow guiding and / or deflecting device which directs and / or diverts the substance-free hot air flow such that the two air flows, preferably at a defined angle of incidence , meet each other and form the flowing from the device substance hot air stream. The outflow channel section thus acts in a dual function at the same time as Strömungsleit- and / or deflection, which helps to reduce the variety of components. In principle, there are various possibilities for arranging the first heating area and the second heating area. According to a preferred embodiment, it is proposed that the first heating region, with respect to a vertical axis direction or use position of the device, is arranged in a geodetically higher and horizontally spaced manner from the second heating region.

According to another particularly preferred embodiment of the invention, it is proposed that the substance-air flow generated by the first heating region flows upward in the vertical axis direction and escapes to the outside of the apparatus via a discharge opening arranged substantially above the first heating region viewed in the vertical axis direction. This allows a functionally reliable and easy delivery of the substance-enriched substance air-flow. According to a further preferred embodiment of the invention can be provided that the outflow channel adjoins the second flow channel associated with the second heating region and, preferably obliquely or inclined to the vertical, is guided in the direction of the first heating region associated discharge opening and there adjacent to the discharge opening opens so that the substance-air flow and the substance-free hot air flow outside of the device meet and form the effluent from the device substance hot air flow. Again, this results in a total of compact design, which is simple to constructively and manufacturing technology. In addition, the outflow angle and thus also the angle of incidence of the substance-free hot air flow can be determined in a simple manner with an outflow channel section aligned obliquely or at an angle.

Particularly preferably, it is provided that the at least one flow and / or deflection is arranged so that these substance-free hot air flow, based on a wall-side mounting position and / or relative to a housing-side connector in the direction of the wall and / or of the connector Guide away and / or guide away. This ensures in a simple manner that the substance-air flow is not condensed on the wall and the substance delivery takes place where it is desired, namely in space. According to another particularly preferred embodiment, it is provided that the angle of incidence between the substance-free hot air stream and the substance air stream is 50 to 80 degrees, preferably 60 to 80 degrees, most preferably 68 to 72 degrees. With such angles of incidence, a functionally reliable and targeted outflow of the two air streams can be achieved, in particular in conjunction with a ratio between the temperature of the wicking substance delivery area and / or the substance air flow and the temperature of the substance-free hot air flow, which is preferably 1: 1, 5 to 1: 2.

The merely exemplary structure of the device according to the invention will be explained in more detail below first with reference to Figures 1 a, 1 b, 2 a and 2 b. These show exemplary cross sections through a possible embodiment of a device 1 according to the invention for dispensing, in particular for vaporizing, volatile substances, such as fragrances and / or active substances.

The device 1 has a housing 2, which may be formed of plastic and / or may be formed in one or more parts. Furthermore, the device 1 comprises a heating device 3 which is arranged and accommodated essentially in the interior of the housing and which forms a separate component which can be displaced relative to the housing 2, which will be explained in more detail below.

The device 1 further comprises a here only dashed and schematically drawn container 4, in which a not shown here, to be dispensed substance is added. This container 4 has a standing in contact with the substance to be dispensed wick 5, which projects beyond the container 4 with a free wick end. This free end of the wick forms a nonwoven substance delivery area 6 associated with the heating device 3.

The container 4 is preferably releasably connected to the housing 2, for example by means of a latching and / or screw connection, which is conventional design and therefore not shown here. The heating device 3 accommodated here in the interior of the housing 2 and formed by a separate component is, as shown in FIG is schematically shown by means of an adjusting device 7 in the vertical axis X displaceable mounted on the housing 2, for example, such that guide arms 8 of the adjusting device 7, which are arranged on the heater 3, engage in housing-side slot recesses 9 as a further component of the adjusting device 7 and there in Hochachsenrichtung X are displaced. In the low position of the heater 3 shown in FIGS. 1a and 1b, the guide arms 8 are in a lower displacement position with respect to the slot recesses 9, while the guide arms 8 in FIG. 2a are in an upper displacement position with respect to the slot recesses 9 located, which then corresponds to a high position of the heater 3.

It is understood that, of course intermediate positions between the low and high positions of the heater 3 shown in Figures 1 a, 1 b and 2a, 2b are possible at any time. It is further understood that the heater 3 is releasably supported in each of the positions, for example, by a latching connection or the like.

It is further understood that the adjusting device 7 shown here together with guide arms 8 and slot recesses 9 is to be understood merely as an example and, of course, any other adjustment device effecting a displacement of the heating device 3 can be provided.

The displaceable heating device 3 is for example essentially formed from a plastic material.

In addition, a first heating element 10 forming a first heating region is mounted on the heating device 3. This first heating element 10 has a radiator 1 1 made of a thermally conductive material, for example made of ceramic, in which an electrical resistance element 12, for example, a PTC resistor, embedded here only by way of example and integrated. This electrical resistance element 12 is connected to the power supply in a conventional manner and not shown here, for example by means of electrical lines, with a here only dashed and schematically illustrated connector 13 electrically connected, which in turn can be connected to a power outlet. It goes without saying that of course every other type of Power supply by means of an energy source is possible, for example by means of a battery or the like.

The first heating element 10 is mounted on the heater 3, that this, seen in the vertical axis X, is located immediately above the container 2 held on the container 4, so that the free wick end as a substance delivery area 6 in a wick recess 14 of the radiator can protrude, as shown schematically in Fig. 1 a and dashed lines. As can be seen further from FIG. 1 a, in the vertical axis direction X, above the first heating element 10 and in particular above the wick recess 14 of the heating element 1 1, there is an outflow opening 19 which is part of the heating device 3 and above a substance-enriched substance-air stream 20 can flow out of the device 1. The substance-air flow 20 is in this case, as will be explained in more detail below, in particular generated by a heat emission of the first heating element 10 to the wick-side substance delivery area 6.

1 b, which shows a section along the line A - A of FIG. 1 a, a second heating element 15, which forms a second heating region of the heating device 3, is also supported on the heating device 3 a radiator 16 is formed of a thermally conductive material, in the here only two examples of electrical resistance elements 17, 18, for example, PTC resistor elements, integrated or embedded. These electrical resistance elements 17, 18 can also be electrically connected to the power supply again in the usual and not shown here, for example by means of electrical lines to the connector 13, which in turn can be connected to a power outlet. It goes without saying that, of course, every other type of energy supply by means of an energy source is also possible here, for example by means of a battery or the like.

As can be seen further from FIG. 1 b, the two exemplary electrical resistance elements 17, 18 are arranged on both sides of a through opening 21 of the heating element 16, and thus of the second heating element 15, which is only approximately centrally arranged here. This passage opening 21 forms a heater side flow channel section

Flow channel 22 off.

As can be seen in particular from the synopsis of FIGS. 1 a and 1 b, a throughflow channel section 23 of the flow channel 22 adjoins this passage opening 21 on the heater side, which is aligned obliquely here and also in the direction of the outflow opening assigned to the first heating element 10 19 is guided and there opens with an outflow or outflow 24 adjacent to the discharge opening 19. It is thereby achieved that a substance-free heating air flow 25 flowing over the outlet channel section 23 of the flow channel 22 strikes the substance air stream 20 at a defined angle of incidence and these two air streams then form a substance-hot air stream 26 flowing out from the device 1, which will be described below is explained in more detail with Fig. 3a.

This chimney-like outflow channel section 23 thus simultaneously forms a flow guiding and deflecting device, by means of which the substance-free hot air flow is directed or directed in a desired manner, so that the two air streams meet outside the device 1 at a predetermined, defined angle of incidence. In particular, as shown in FIG. 3b, this angle of incidence α may be 50 to 80 degrees, preferably 60 to 80 degrees, most preferably 68 to 72 degrees.

As can be seen in FIG. 1 a in conjunction with FIG. 3 a, the outflow channel section 23 is here inclined away from the connection plug 13 and thus away from a wall 40 such that the substance-free hot air flow 25 forms the substance air flow 20 and thus the Substance hot air stream 26 in the direction of the wall 40 and in the direction of the connector 13 leads away or deflects. The passage opening 21 of the radiator 16 of the second heating element 15 thus forms together with the adjoining Abströmkanalabschnitt 23 a heater side component of the flow channel 22, which also also, as can be seen in particular from Fig. 1 b, here an example of the housing side first Flow channel section 27, via which the means of the second heating element 15 to be heated air 28 flows into the flow channel 22. The first flow channel section 27 and the throughflow opening 21 of the heating element 16 forming a second flow channel section are fluidically coupled or connected in an abutment region 29, which can be seen in particular from FIG. 1 b. In this adjoining region 29, the heating device 3 with a wrap-around wall region 31 surrounds a wall region 30 forming the first flow channel section 27 from outside, preferably substantially gas-tight from the outside. This wraparound is preferably designed such that the wraparound wall region 31 of the heating device 3 engages around the wall region 30 of the housing 2 forming the first flow channel section 27 in each displacement position of the heating device 3. In principle, however, the wall region 30 of the housing 2 forming the first flow channel section 27 could, in an equivalent manner, also form the enveloping wall region and engage around the correspondingly assigned wall region of the heating device 3 from the outside.

As can be seen in particular in FIG. 1 b, in the adjoining region 29 between the first flow channel section 27 and the second flow channel section forming through opening 21 arranged by the air flow to be heated 28 throttle body 32 as part of a throttle element. This throttle body 32 is seen here by way of example in the flow direction of the air flow to be heated 28, upstream of the second heating element 15 and forms here further example of a part of the housing-side first flow channel section 27th

Specifically, the throttle body 32 has a piston-like shape with respect to the cross-section shown in FIG. 1 b, here two adjoining 29, end, left and right side inclined surfaces 33, which at the through hole 21 a, an inclined surface with the substantially same inclination extending flow channel wall portion 34 is assigned to form an obliquely extending overflow channel section 35.

It is understood that the explanations just made are based only on the cross section shown in FIG. 1 b and that, of course, embodiments are possible in which the throttle body 32 ends a Has annular side circumferential inclined surface 33, which is assigned to the passage opening 21 a corresponding annular peripheral wall portion 34 with a corresponding inclined inclined surface. Here, in connection with FIG. 1 b, only the illustration of the basic principle relating to an overflow channel section 35 between, on the one hand, the first flow channel section 27 and the second flow channel section formed by the through opening 21.

As can be further seen from the representation of FIG. 1 b, the throttle body 32 also has a gap spacing with respect to an inner wall region 36 of the first flow channel section 27 surrounding the throttle body 32, such that a throttle body 32 is provided between the throttle body 32 and the surrounding inner wall region 36 Überströmkanalabschnitt 35 fluidly connected throttle body Umströmungskanalabschnitt 37 is formed, via which the flowing into the first flow channel section 27, to be heated or the throttle body 32 incoming air stream 28 around the throttle body 32 around to the overflow channel 35 and thus further into the through hole 21 into it. As can be seen in particular from the synopsis of Fig. 1 a, 1 b, 2 a and 2 b, takes place at a displacement of the heater 3 from the low position shown in Figs. 1 a and 1 b in the in Figs. 2a and 2b shows a relative displacement between the heating device 3 and the housing 2 and thus also a relative displacement between the housing-side first flow channel section 27 and the second flow channel section forming heater side passage opening 21 instead, which has the consequence that the flow cross-section , in particular the overflow cross section between the first flow channel section 27 and the through opening 21 as a second flow channel section, changes in the adjoining region 29.

The actuation of the adjusting device 7 during the transition from the low position shown in Figs. 1 a and 1 b in the high position shown in Figs. 2a and 2b causes on the one hand a change in the relative position or the distance of the free wick end as a substance delivery area 6 of the first heating element 10 and further also a change in the flow cross section in Flow channel 22 to the effect that the distance between the inclined surfaces 33 of the throttle body 32 and the wall portion 34 of the through hole 21 and thus the Überströmquerschnitt from the first flow channel section 27 to the through hole 21 as a second flow channel section is increased.

In the low position of the heating device 3 shown in FIGS. 1 a and 1 b, the free wick end as substance delivery region 6 is located deep inside the wick recess 14 and is therefore subjected to a relatively large amount of heat when the electrical resistance element 12 is activated that a correspondingly large amount of substance is discharged from the substance delivery area 6 and a substance air stream 20 loaded with a relatively large amount of substance is produced.

Next, the throttle body 32 in the low position only such a small distance to the associated flow channel wall portion 34, that the overflow channel 35 has a minimum flow cross-section, in particular a minimum overflow cross-section, whereby the residence time of the air to be heated in the passage opening 21 of the radiator 16 of the second Heating element 15 is greater than in the high position of the heater shown in FIGS. 2a and 2b, in which the throttle body 32 is arranged at such a large distance to the associated flow channel wall region 34, that the overflow channel section 35 has a maximum flow cross-section, in particular a maximum overflow ,

Due to the longer residence time of the air flow to be heated in the passage opening 21 in the low position, it is achieved that the air flow to be heated by the second heating element 15 is ultimately heated to a higher temperature than in the high position of the heater, in which the residence time of the air flow to be heated In contrast, in the region of the passage opening 21 is lower. Accordingly, in the low position of the heating device 3, a hotter substance-free hot air stream 25 flows upwards over the outflow channel section 23 than is the case when the heater 3 is raised, so that in the low position shown in FIGS. 1 a and 1 b a substance-free hot air stream 25 with a relatively high temperature (and possibly a relatively high flow velocity) encounters a substance-air flow 20, which is enriched by the high heat application of the substance delivery area 6 by means of the first heating element 10 strongly with substance. On the other hand, in the high position of the heating device 3 (FIGS. 2 a and 2 b), a substance-free hot air stream 25 having a lower temperature encounters a substance air stream 20 which is enriched in the low position with less substance than the substance air stream. This is due to the fact that by the positively coupled displacement of the two heating elements 10, 15 by means of the heater 3 at the transition from the low position to the high position at the same time the distance or the relative position between the free wick end as substance delivery area 6 and the first heating element 10th is changed (see in particular Fig. 2a), in such a way that the substance discharge area 6 formed by the free end of the wick is now located opposite to the low position farther away from the first heating element 10 or is subjected to less heat than in the low position less substance is delivered and accordingly a compared to the lower position with less substance enriched substance-air stream 20 is generated.

Upon actuation of the adjusting device 7 thus the two, part of the heater 3 forming heating elements 10 and 15 together and thus forcibly coupled shifts to ensure that in the low position, a hot substance-free hot air stream 25 meets a substance-enriched air stream 20, while in the superscript position, a substance hot air stream 25 which is less hot than the low position impinges on a substance air stream 20 enriched with less substance than the low position.

It is understood that, as already stated above, in principle also the possibility exists to adjust by means of the adjusting 7 intermediate positions of the heater 3, which lie between the low and high position shown in Figs. 1 a, 1 b, 2 a and 2 b.

Of particular advantage is an interpretation of the device 1 and its individual components, which ensures that in each set by means of the adjusting device 7 displacement position of the heater 3 relative to the housing 2 a defined, predetermined ratio between the temperature of dochtseitigen substance delivery area 6 and Temperature of the substance-free hot air stream 25 is set. This ratio between the temperature of the wicking side substance delivery region 6 and the temperature of the substance-free hot air stream 25 is preferably 1: 1.5 to 1: 2, preferably based on a temperature of the wicking side substance delivery region of 60 to 150 ° Celsius.

In particular, with such a ratio and / or with an impact angle α between the substance-free hot air stream 25 and the substance-air flow of 50 to 80 degrees, preferably 60 to 80 degrees, most preferably 68 to 72 degrees, results in a particularly effective substance delivery into a room or the efficiency of such substance delivery is substantially improved or increased, which is explained in more detail below in connection with FIG. 3a:

In particular, in the above relationship between the temperature of the wick-side substance delivery region 6 and the temperature of the substance-free hot air stream 25 and / or at an impact angle as indicated above, a substance hot air stream 26 can be obtained which is characterized in that the two of the device 1 flowing away and the substance hot air stream 26 forming air streams do not mix and flow away over a relatively long distance as parallel currents upwards from the device 1. The air streams forming the substance hot air stream 26 thus form a stable convection flow in the region I of FIG. 3 a.

At the end of the region I, that is to say when the transition to region II is indicated by the arrow 38, there then occurs a scattered breakage or collapse of the boundary layers of the air streams forming the substance hot air stream 26, ie a less stable convection current begins than in the region I. train. This has the consequence that it comes to breaking or the formation of individual substance bubbles or droplets 39, which are discharged into the room. However, as shown in FIG. 3a, because of the still relatively stable convection current or the still present substance-free hot air flow within the substance hot air flow 26, this discharge does not take place in the direction of a wall 40 but in the opposite direction and thus in the desired direction Direction into the room. As soon as the substance hot air stream 26 has reached its end height (terminal height) indicated by the arrow 41 at the end of the region II, it occurs finally to the formation of an unstable convection flow, which then leads to the substance bubbles flowing with the substance-hot air stream 26 or droplets 39 are discharged in the desired manner into the room, and significantly above the final height 41st

The statements made above relate in each case to the case that both in the low position and in the high position of the heating device 3 or in any intermediate positions between these two positions both from the first heating element 10 and the second heating element 15 each have an equal heating power is delivered that is, both the electrical resistance element 12 of the first heating element 10 and the two electrical resistance elements 17, 18 of the second heating element 15 are activated, which is in the figurative representations of Figures 1 a, 1 b, 2a and 2b respectively marked "ON" ,

In principle, it is also possible to vary the heat output of the first heating element 10 and / or the second heating element 15, that is, it is possible to additionally influence the temperature of the substance-free hot air flow 25 by, for example, one of the electrical resistance elements 17, 18 of the second heating element 15 is not activated, to name just one example. Further alternatively, there is also the fundamental possibility of providing no displaceability of the first flow channel section 27 relative to the heater side flow channel section and thus to dispense with throttling by means of a throttle element. In this case, the temperature of the substance-free hot air stream 25 can then be adjusted solely by the heat output of the electrical resistance elements 17, 18. In all of the two above-mentioned alternative cases, it is likewise of particular advantage to keep the abovementioned ratio between the temperature of the nonwoven substance delivery region 6 and the temperature of the substance-free hot air stream 25 in the desired range.

Although only one electrical resistance element 12 has been used in connection with the first heating element in the above figurative representations, it goes without saying that, of course, more than one electrical resistance element could also be a component of the first heating element 10. Likewise, it is understood that the second heating element 15, only one single electrical resistance element could be provided or even more than two electrical resistance elements could be provided. The number and size of the respective electrical resistance elements is preferably determined by the respective desired heating power of the first heating element 10 and the second heating element 15 in the different adjustable with the adjusting device 7 positions, in particular in the low position and the high position.
