Description

  The present invention relates to an interior space cleaning system that includes an electrostatic atomizer that generates charged fine particle water and cleans the interior space.

  In vehicles such as passenger cars, odors such as cigarettes may be trapped in the interior space, particularly in the interior of the vehicle, and as a countermeasure against this, conventionally, air in the interior of the vehicle is taken in and passed through a filter to be cleaned and returned to the interior of the vehicle. Although a filtration-type air cleaning device is provided, this type of air cleaning device cannot remove even odorous components adhering to the wall surface, seat, or the like in the passenger compartment.

  On the other hand, in recent years, electrostatic atomizers that generate nanometer-sized charged fine particle water (nanosize mist) by electrostatically atomizing water have attracted attention. Since the charged fine particle water generated by the electrostatic atomizer contains radicals such as superoxide radicals and hydroxy radicals, in addition to the deodorizing effect, it also has an inactivating effect for allergen substances. Therefore, if the charged fine particle water is sent out into the vehicle interior, not only the odor components in the air in the vehicle interior, but also the odor components attached to the walls and seats in the vehicle interior can be deodorized, Suppresses allergens such as tick mushrooms adhering to seats, floor carpets, cushions, etc., and pollen and other substances that enter the passenger compartment and are brought into the passenger compartment by opening and closing doors outdoors. There is also an effect.

  As a technique for applying this type of electrostatic atomizer to a vehicle, the electrostatic atomizer and the air conditioner provided in the vehicle are operated simultaneously, and the charged particulate water generated by the electrostatic atomizer is generated by the air conditioner. It has been proposed to discharge the vehicle interior by an air flow (see, for example, Patent Document 1).

  In addition, it has also been proposed to spread charged fine particle water over a wide area in the passenger compartment by attaching an electrostatic atomizer to the ceiling of the passenger compartment (see, for example, Patent Document 2).

By the way, the charged fine particle water generated by the electrostatic atomizer is in addition to the above-described deodorizing and inactivating effects of allergen substances, in addition to the effect of maintaining the freshness of food such as vegetables and fruits, that is, the effect of suppressing the drying of food. It is also known that it has the effect of suppressing viruses and molds.

  However, in the configuration in which the charged particulate water is discharged into the vehicle interior using the airflow generated by the air conditioner as described above, the charged particulate water becomes a hindrance to the airflow by the seat, the occupant, etc. It is difficult to get to. Therefore, when the food brought into the vehicle is placed in, for example, a rear seat or a luggage space, the effect of maintaining the freshness of the food by charged fine particle water cannot be expected.

  Also, if the vehicle has a vehicle refrigerator, it is assumed that perishable food will be stored in the vehicle refrigerator, but if the interior of the vehicle refrigerator is a sealed space, The food in the vehicular refrigerator cannot enjoy the effect of maintaining the freshness by the charged fine particle water.

  Further, by installing the electrostatic atomizer on the ceiling of the passenger compartment as described above, the charged fine particle water generated by the electrostatic atomizer even if the charged fine particle water reaches the rear seat or the luggage space. The amount of charged fine particle water adhering to the food is smaller than that of the food, and the effect of maintaining the freshness of the food is lower than when the food is placed near the electrostatic atomizer.

  As described above, in the conventional technology in which a single electrostatic atomizer is applied to a vehicle, the charged fine particle water is beneficial in a place where the charged fine particle water is not sufficiently supplied from the electrostatic atomizer even in the interior space of the vehicle. Since it may not be sufficiently received, the effect of charged fine particle water that can be actually enjoyed is limited. Therefore, there is a demand for a technique for realizing a more convenient and comfortable vehicle interior space by sufficiently enjoying the effect of charged fine particle water.

  The present invention has been made in view of the above-described reasons, and an object thereof is to provide a vehicle interior cleaning system that can realize a vehicle interior that is more convenient and more comfortable than before.

  In the invention of claim 1, an electrostatic atomizer that generates charged fine particle water by supplying water from a water supply means to the discharge electrode and applying a high voltage to the supplied water to cause electrostatic atomization; A light irradiating device that irradiates light in a wavelength range that has a specific effect on an irradiation target in the atmosphere in which the charged fine particle water exists, and the electrostatic atomizer is disposed at a plurality of locations in the vehicle, The apparatus emits light in conjunction with the electrostatic atomizer as a supply source of the charged fine particle water to a space where the charged fine particle water is supplied from at least a single electrostatic atomizer in the vehicle. And

  According to this configuration, since the electrostatic atomizer is disposed at a plurality of locations in the vehicle, for example, a space for placing food, such as a luggage space, or odors such as the feet of an occupant, an ashtray, and a trash can easily accumulate. By disposing the electrostatic atomizer in a space or an independent space such as a trunk room or a vehicular refrigerator, it is possible to enjoy the effect of charged fine particle water at each of the plurality of locations in the vehicle. In other words, compared to the conventional technology that supplies charged fine particle water into the vehicle interior with a single electrostatic atomizer, the reach of charged fine particle water in the vehicle interior can be broadened, realizing a more convenient vehicle interior space. can do. In addition, the light irradiation device irradiates the space where charged fine particle water is supplied from at least one electrostatic atomizer in the vehicle in conjunction with the electrostatic atomizer which is a supply source of the charged fine particle water. Because it irradiates light in a wavelength range that has a specific effect on the target, for example, when food such as vegetables and fruits is brought into the vehicle, the food is irradiated with light in a wavelength range that has bactericidal and deodorizing effects. Compared with the configuration using only the electrostatic atomizer, the effect of maintaining the freshness of the food can be enhanced, and a more comfortable interior space can be realized.

  According to a second aspect of the present invention, in the first aspect of the invention, an individual control means for individually controlling the operations of the plurality of electrostatic atomizers is provided.

  According to this configuration, since the operations of the plurality of electrostatic atomizers are individually controlled, only the necessary electrostatic atomizers can be operated, for example, although no ashtray is used. It is possible to prevent useless operations of the electrostatic atomizer such as when the electrostatic atomizer that discharges charged fine particle water to the ashtray is operating.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, there is provided a manual control means for controlling the operation of the electrostatic atomizer in accordance with an operation of a manual operation unit installed in the vehicle. .

  According to this configuration, since the operation of the electrostatic atomizer is manually controlled, the electrostatic atomizer can be operated only when the occupant is required, and wasteful power consumption by the electrostatic atomizer is possible. Can be eliminated.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, the apparatus further comprises an automatic control means for automatically controlling the operation of the electrostatic atomizer in accordance with an output of a sensor installed in the vehicle. It is characterized by.

  According to this structure, since operation | movement of an electrostatic atomizer is controlled automatically, there exists an advantage that a passenger | crew does not have the effort of manual operation.

  The invention of claim 5 is the suction device according to any one of claims 1 to 4, wherein the electrostatic atomizer sucks air from a suction port provided in a space for supplying the charged fine particle water. It is characterized by being linked to.

  According to this configuration, since the air flow is generated by the suction device in the space to which the charged fine particle water is supplied, it is possible to prevent the air contaminated in the space from stagnating. Moreover, there exists an advantage that the charged fine particle water which the electrostatic atomizer produced | generated can be spread over a wide range compared with the case where there is no said air flow.

  According to a sixth aspect of the present invention, in any one of the first to fifth aspects, the light irradiation device includes a light emitting diode as a light source.

  According to this configuration, for example, there is an advantage that light in a necessary wavelength range can be efficiently irradiated as compared with a case where a light source that outputs light in a broad wavelength range such as an incandescent bulb is used.

  In the present invention, electrostatic atomizers are disposed at a plurality of locations in a vehicle, and the light irradiation device is disposed in a space where charged particulate water is supplied from at least one electrostatic atomizer in the vehicle. On the other hand, in conjunction with the electrostatic atomizer that is the supply source of the charged fine particle water, light in a wavelength range that brings a specific action to the irradiation target is irradiated, so the interior space is more convenient and comfortable than before. There is an advantage that can be realized.

The light irradiation devices B1 and B2 are arranged in the designated spaces Z1 and Z7 so as to irradiate the designated space Z1 and the designated space Z7, respectively.

  As shown in FIG. 2, the electrostatic atomizer A includes a discharge electrode 6 formed in a tapered cylindrical shape, a counter electrode 7 facing the discharge portion 6 a formed at the tip of the discharge electrode 6, A water supply means 8 for supplying water to the discharge part 6a and a high voltage application means 9 comprising a high voltage power source for applying a high voltage between the discharge part 6a and the counter electrode 7 are provided, and a discharge part (discharge electrode) 6a. By applying a high voltage between the counter electrode 7 and the counter electrode 7 to generate corona discharge, the water supplied to the discharge part 6a is electrostatically atomized to generate charged fine particle water M.

  Here, the water supply means 8 is composed of a Peltier unit that cools the discharge electrode 6, and supplies water to the discharge electrode 6 by cooling the moisture in the air and generating condensed water. The Peltier unit includes a pair of Peltier circuit boards 10 and 11 formed by forming conductor patterns 10a and 11a on one side of an insulating plate made of alumina or aluminum nitride having excellent thermal conductivity. Oppositely facing each other, BiTe thermoelectric elements 12 arranged in a large number of rows are sandwiched between the two Peltier circuit boards 10 and 11, and the adjacent thermoelectric elements 12 are electrically connected by the conductor patterns 10a and 11a on both sides. It is a thing. In this configuration, when the Peltier unit is energized through the lead wire 13, heat is transferred from one Peltier circuit board 10 side to the other Peltier circuit board 11 side. Here, the discharge electrode 6 is thermally coupled to the one (cooling side) Peltier circuit board 10, and the radiation fins 14 are coupled to the other (heat radiation side) Peltier circuit board 11. Yes.

  The discharge electrode 6 is surrounded by a cylindrical tube 15 made of an insulating material. The counter electrode 7 is formed in a ring shape in which a mist discharge port 7 a is opened at the center, and is disposed on the tip opening surface (upper surface in FIG. 2) of the cylindrical body 15. Here, since the center of the mist emission port 7a of the counter electrode 7 is located on the extension line of the axial center of the discharge electrode 6, the discharge electrode 6 and the counter electrode 7 face each other with a predetermined distance. A plurality of ventilation openings 15 a are opened in the peripheral wall of the cylinder 15, and the mist discharge openings 7 a and the ventilation openings 15 a of the counter electrode 7 communicate with each other in the internal space of the cylinder 15.

  Further, a high-voltage lead wire 16 electrically connected to the discharge electrode 6 passes through the peripheral wall of the cylinder 15 and is drawn to the outside of the cylinder 15, and the high voltage application means 9 is configured so that the discharge electrode 6 side is negative. By applying a high voltage between the high-voltage lead wire 16 and the counter electrode 7 with the polarity as described above, a high voltage is applied between the discharge part 6 a and the counter electrode 7.

  Accordingly, when the Peltier unit is energized, the discharge electrode 6 is cooled, moisture in the air is condensed, and water (condensed water) is supplied to the surface of the discharge part 6a. In this state, when a high voltage is applied between the discharge electrode 6 and the counter electrode 7, the water on the surface of the discharge part 6 a exceeds the surface tension and repeatedly splits and scatters (Rayleigh split), and is negatively charged. A large amount of charged fine particle water M is generated. The generated charged fine particle water M is discharged to the outside from the mist discharge port 7a of the counter electrode 7 provided on the tip opening surface of the cylindrical body 15.

  The electrostatic atomizer A configured as described above is configured such that the mist discharge port 7a faces the designated spaces Z1 to Z7 so that the charged fine particle water M is discharged into the corresponding designated spaces Z1 to Z7, respectively. Be placed.

  On the other hand, the light irradiation device B includes a light source (not shown) that generates light in a predetermined wavelength range and a lighting circuit (not shown) that turns on the light source. In this embodiment, a light emitting diode (LED) is used as the light source.

  Here, it is known that light has various effects on an irradiation target depending on its wavelength range. For example, light in the ultraviolet region has bactericidal and deodorizing effects, and if vegetables are irradiated with light in the blue wavelength range or light in the orange wavelength range, the photosynthesis of the vegetables is promoted and the freshness is maintained. If the light of a blue wavelength range is irradiated with respect to a passenger | crew, there exists an effect | action that a passenger | crew's mood can be calmed down. In the present embodiment, assuming that food such as vegetables and fruits is brought into the vehicle as an example, the light irradiation device B1 that irradiates the designated space Z1 with light in order to maintain the freshness of the food is a blue wavelength region. The light irradiation device B2 that irradiates the designated space Z7 irradiates light in the ultraviolet region.

  By the way, the vehicle interior cleaning system of the present embodiment includes a control means C for controlling the operations of a plurality of electrostatic atomizers A and a light irradiation device B as shown in FIG. Are connected to a manual operation unit H and a plurality of sensors S provided in the vehicle.

  Although the control means C may control the operation | movement of several electrostatic atomizer A collectively, here, as an individual control means which controls operation | movement of each electrostatic atomizer A separately, It shall function. Therefore, only the desired electrostatic atomizer A among the plurality of electrostatic atomizers A can be operated. The manual operation unit H is a switch group (not shown) provided on the instrument panel 4, and the control means C controls the operation of each electrostatic atomizer A according to the operation of the manual operation unit H. Note that the manual operation unit H may be provided individually for each of the designated spaces Z1 to Z7.

  Further, the control means C controls the operation of the electrostatic atomizer A according to the output of each sensor S in addition to the manual control means for controlling the operation of the electrostatic atomizer A according to the operation of the manual controller H as described above. It also functions as an automatic control means for automatically controlling. Here, switching between the manual control mode in which the control unit C functions as the manual control unit and the automatic control mode in which the control unit C functions as the automatic control unit is performed by operating a mode switching switch (not shown) provided in the manual operation unit H.

  As the sensor S, for example, a sensor that detects the temperature and humidity in the vehicle, a sensor that detects the presence of a person, a sensor that detects the smell of a designated space, a sensor that detects the opening and closing of the door of the vehicular refrigerator 5 are used. During the operation in the automatic control mode, whether or not to operate each electrostatic atomizer A is automatically determined from the output of each sensor S. That is, for example, regarding the electrostatic atomizer A7 corresponding to the designated space A7 in the vehicular refrigerator 5, the operation of the electrostatic atomizer A7 is stopped during the period when the door of the vehicular refrigerator 5 is open. When closed, the electrostatic atomizer A7 is controlled to operate. The sensor S may be provided individually for each designated space.

  Here, the light irradiation devices B1 and B2 are controlled by the control means C so as to be interlocked with the electrostatic atomizers A1 and A7 associated with the designated spaces Z1 and Z7 that are the irradiation targets of light, respectively. That is, the light irradiation device B1 that irradiates light to the designated space Z1 operates in accordance with the operation of the electrostatic atomizer A1 that discharges the charged fine particle water M to the designated space Z1, and is irradiated from the light irradiation device B1. The light acts on the object existing in the designated space Z1 in parallel with the charged fine particle water M. On the other hand, the light irradiation device B2 that irradiates light to the designated space Z7 operates in accordance with the operation of the electrostatic atomizer A7 that discharges the charged fine particle water M to the designated space Z7, and is irradiated from the light irradiation device B2. The light acts on the object existing in the designated space Z7 in parallel with the charged fine particle water M.

  Note that the power for the electrostatic atomizer A, the light irradiation device B, the control means C, etc. may be supplied directly from the battery of the vehicle, or may be supplied by being branched from the ignition line. Good. With the former configuration, the electrostatic atomizer A and the light irradiation device B can be operated regardless of whether the ignition switch is on or off. With the latter configuration, the electrostatic atomizer only when the ignition switch is on. Activating device A and light irradiation device B can be activated.

  According to the configuration described above, the electrostatic atomizer A is locally disposed at various locations in the vehicle, so that the effect of the charged fine particle water M generated by the electrostatic atomizer A is maximized at various locations in the vehicle. It is possible to enjoy. That is, the deodorizing effect by the charged fine particle water M can be expected in places where odors are likely to stay, such as the designated spaces Z2 and Z3 set in the passenger's foot space and the designated space Z4 set in the internal space of the ashtray, On the other hand, in the designated spaces Z5 and Z6 set in the overhead space of the occupant, effects such as reduction of occupant hair damage and moisturizing the face can be expected. For example, when bringing food such as vegetables and fruits into the vehicle, the food is placed in the designated spaces Z1 and Z7, and the electrostatic atomizer A corresponding to the designated spaces Z1 and Z7 is operated. The freshness of the food can be maintained by the charged fine particle water M generated by the electrostatic atomizer A.

  Further, regarding the designated space Z1 set as the luggage space, light (here, blue light) is irradiated from the light irradiation device B1 in conjunction with the electrostatic atomizing device A1, so that the charged fine particle water M and the light The effect of maintaining the freshness of the food is improved by the synergistic effect. Furthermore, with respect to the designated space Z7 in the vehicular refrigerator 5, light (in this case, ultraviolet light) is irradiated from the light irradiation device B2 in conjunction with the electrostatic atomizer A7. The effect of maintaining the freshness of the food is improved by a synergistic effect.

  In addition, when the trash box is installed in the vehicle, it is desirable to set the designated space in the trash box and arrange the electrostatic atomizer A. Thereby, the deodorizing effect in the trash can can be expected. Further, the electrostatic atomizer A may be disposed in a designated space in an independent space such as a trunk room as well as in the passenger compartment. In the case of a trunk room, it is also possible to store food, so it is desirable to also arrange a light irradiation device B that works in conjunction with the electrostatic atomizer A. When a relatively wide space is designated as a designated space, such as in a trunk room or a large-capacity refrigerator 5 for a vehicle, a plurality of electrostatic atomizers A are provided for one designated space. By simultaneously operating the atomizing device A, the charged fine particle water M can be spread over the entire designated space.

  The suction device D includes a motor fan (not shown), and sucks air in the designated space Z1 from the suction port by rotating the motor fan. As a result, an air flow F is formed in the designated space Z1.

  As a result, the contaminated air can be prevented from staying in the designated space Z1. Further, the charged fine particle water M discharged from the electrostatic atomizer A1 can be carried to every corner of the designated space Z1 by the air flow F, and the range that the charged fine particle water M reaches can be expanded. Further, since the electrostatic atomizer A1 condenses moisture in the air of the designated space Z1 by the water supply means 8, by sucking the air containing the charged particulate water M from the designated space Z1 by the suction device D, The designated space Z1 can be dehumidified.
