Description

The invention relates to an air-permeable hair drying or shaping device as defined in claim 1.

The applicant's application for the grant of a Community patent for a device of this type is based on the following information: the applicant's patent application for a device of this type is based on the application for a patent for a device of this type, for example, on the application for a patent for a device of this type, EP 0103205 B1 (code No 04994), which is also attributed to the applicant, and to which reference is made in the present application for the purpose of its disclosure.

DE 25 29 809 A1 is a hair dryer according to the general concept of claim 1, where the outgoing air can be directed through a hollow profile. The purpose of this device is to direct the hot air in such a way that it flows through the hair as well as possible and does not hit the user's scalp. The air-filled hollow teeth can be equipped with a manually adjustable air vent so that the outgoing air flow can be achieved, depending on the position of the air vent in the lower or upper part of a hollow vent or on a further design of this device, by improving the position of the air vent and the force acting on it.

The purpose of the invention is to develop a device of the type described at the outset to enable specific hair sections to be dried or shaped by means of air-filled devices while at the same time making it easy to operate. This task is essentially solved by attaching a hinged device to the supporting element and by arranging the supporting element in a way that the housing can be deflected before the air outlet, with part of the breakages of the supporting element being locked by means of the blotting device and the deflection of the supporting element by the force applied to the hair by the hair during the curling or shaping.In particular, it is possible to dry the hair follicles to make them stand upright. The hot air stream is passed through the scalp and prevents an unpleasantly high heating of the scalp. When the hair-holding elements are immersed in the hair and the device is rotated along the longitudinal axis, the support element with the hair-holding elements is first fixed due to the resistance of the hair. The subsequent combing or brushing process causes a twisting or rotation movement, i.e. a deviation of the support element in relation to the device, whereby a part of the breakthroughs of the hair-holding element is targeted by a forward direction.The symmetrical structure of the arrangement means that, depending on the direction of brushing or combing, i.e. either from left to right or from right to left, a different part of the incisions of the supporting plate is automatically closed and the air flow through the other open part of the incisions is directed directly to the hair to be dried or shaped. The operation of the apparatus is extremely simple and does not require the operation of additional switches or controls to perform the targeted hair drying, since the leaf device automatically sets itself up according to the direction of combing or left.

The device is designed in such a way that the supporting element is connected to a spring which stabilizes the supporting element in relation to the housing in a resting position. This makes it possible to fix the supporting element in relation to the housing of the device during non-use. However, even during use, the advantage is that the device can be used as a conventional hair dryer, provided that the hair-holding elements do not penetrate the hair.

The fact that the supporting element is mounted on the housing in a way that it can be rotated around a pivoting axis gives rise to a particularly advantageous deflection of the supporting element relative to the housing, adapted to the brushing or combing process.

The device is further advantageously designed to be fixed on the side of the housing and to form a lattice for the outlet. The aperture not only closes part of the break-throughs of the supporting element depending on its deflection but also prevents the user from coming into contact with the electrical conductive parts of the apparatus.

According to another advantageous development of the invention, the aperture device has at least two independently moving aperture elements, which are connected to each other by means of the spring element. This design is particularly useful when the number of break-throughs of the support body exceeds a certain value and the air flow from the device is not to be too much reduced when the support element is deflected.

The advantage is that the two or more of the lens elements are movable relative to the supporting element and relative to the housing, and are arranged on the apparatus, in particular on the supporting element, which allows individual control of the lens elements when the supporting element is deflected.

In a particularly advantageous development of the invention, the aperture device consists of a part of the aperture fixed to the housing and preferably two independently moving aperture elements which are pre-loaded to the aperture part. By the interaction of the aperture part with the aperture elements, an interchangeable opening and closing of individual air outlets of the aperture part can be realized, so that air can be drawn out from individual gaps in the support part, without having parts of an aperture advantage on the support itself.

The aperture attached to the housing is advantageous in forming a grid for the air outlet.

In a more advantageous development of the invention, the aperture elements are displacement-capable in relation to the housing, the aperture part and the supporting element on the apparatus, in particular on the aperture part, which allows the aperture elements to achieve highly variable control of air flows by their individual displacement.

In a further development of the invention, the carrier element and the aperture part have means of attachment for the aperture elements to their alternate and opposite movements in the direction of deflection of the carrier element, so that the aperture elements, depending on whether the carrier element is at rest, grounded or in a reclining position, can allow an almost unimpeded outflow of air when covered with the aperture part or cover individual apertures of the aperture part, thus preventing air from flowing through individual breaches of the carrier part and providing an exact air conduction to certain hair areas.

The advantage is that the supporting element can be fixed to the housing by means of a locking device.

The carrier element is removable from the housing, particularly for cleaning purposes, after further development of the invention.

Another solution is to provide a deflectable air conductor to control the airflow, which can be deflected by the force applied to the hair-holding elements to dry the hair particularly intensively in the area of the hair tips.

In an advantageous design, the air conductor is divided into two parts and consists of the air outlet grille and at least one movable aperture element, the aperture element being movable through the supporting element; the compression or brush movement causes the supporting element to be deflected, the at least one movable aperture element being moved relative to the air outlet grille and the air outlets of the grille being closed alternately according to the direction of compression or brush, thus controlling the air flow through the carrier part's gaps.

Further features, advantages and applications of the invention are shown in the following description of the embodiments, which are described in more detail in the drawings.

It shows: Figure 1a, a longitudinal section of the air-permeable apparatus according to a first embodiment of the invention,Fig. 2a, a leg section of the apparatus according to II-II of Figure 1 with the supporting element in the resting position or in a backrest,Fig. 3a, a partial longitudinal section of the apparatus according to the invention according to a second embodiment of the invention,Fig. 4a, a leg section of the apparatus according to IV-IV of Fig. 3 with the supporting element in the third backrest or in a backrest, andFig. 5a, b, c, a basic representation to explain the implementation of the function of the second example according to Figure 3, Part 4,Fig. 6a, a partial longitudinal section of the apparatus according to Figure 7a, a partition of the apparatus according to the invention, with a supporting element according to Figure 6a, and a section of the apparatus according to Figure 6a,

The figures show a device 10 for hair drying or shaping which is air-flowing. The device has a housing 12 with an air intake 14 and an air outlet 16. In the area of the air intake 14 an electric motor 18 is located which drives a fan wheel 20. The air supplied by the fan wheel 20 passes through a heater 22 and exits through the air outlet 16 from the device 10. Between the heater 22 and the air outlet 16 there are air elements 24 which support the office air flow power at approximately a right angle relative to the axis of the threshold. A switch 26 passes through the heater wheel 20 and the air heater 20 is heated 22 and exits through the air outlet 16 from the device 10.

The side of the support element 30 facing the air vent 16 is fitted with a hinged device 36. The support element 30 is deflectable, in particular by means of a swing axis 38 adjustable to the housing 12 of the apparatus 10 by means of two bearings 40, 42.

According to the first embodiment of the invention shown in Figures 1 and 2, the support element 30 has three parallel longitudinal holes 32 which may be interrupted in the direction of their longitudinal extension by smaller cross-sections. The aperture device 36 attached to this support element 30 consists of two longitudinal steps firmly connected to the housing 12 and forms a grid 54 for the air outlet 16. The support element 44 is designed as a bent leaf spring fixed at the outer end of the spring 12. The end-points of the leaf spring are fixed in the direction of their longitudinal extension by smaller cross-sections. The two apertures 30 No 30 (Fig. 2a) and 30 No 30 (Fig. 30a) are fixed at the left side of the support element. The force of the collapse of the spring 32 (Fig. 32a) is limited to a certain distance, and the air flow is not allowed to pass through the spring in a certain direction. The two apertures 32 (Fig. 32a) and 32 (Fig. 30a) are only two at the left side of the support element 30 No 30 (Fig. 30a) and the other two are fixed at the left side of the support element 30 (Fig. 32a) The air flow is not allowed to pass through the spring in a certain direction.

The deflection of the supporting element 30 is caused by the force exerted on the hair-holding elements 34 during hair drying or shaping, so that the backward break 32 is opened in relation to the direction of combing or brushing.

The second embodiment of the invention, shown in Figures 3.4 and 3.4, shows that the aperture device 36 has two independently moving aperture elements 56, 57 which are connected to each other by means of the spring element, in particular a spiral spring. Each of the aperture elements 56, 57 consists of two longitudinal bars connected slightly apart. The support element 30 has five longitudinal holes 32 in this case. The end sections of the aperture elements 56, 57 are formed as holes 58, 9 with the support element 30 carrying the aperture 60, 61 and the running device 62, 63 for the holes 58, 57 and 57 of the aperture elements. Each of the five moving elements 56 57 is adjustable to the other in the opposite direction of the aperture element 56 and 56 57 is adjustable to the other.

The basic operation of the embodiments of Figures 3 and 4 is shown in Figure 5. Comparable parts are designated with identical reference numbers. In Figure 5a, the supporting element 30 is shown in the resting position (Fig. 4a) in relation to the housing 12. The supporting element 30 is moved into the resting position by the spring force of the spring element 44 which is located between the lens elements 56 and 57. The lens elements 56, 57 act on the supporting elements 60, 61 of the supporting element 30 and thus exert a resting force on the supporting element 30.If a force is exerted on the supporting element 30 to the left (Fig. 5b) through the haircuts 34, the breakthroughs 32 in the supporting element 30 will shift according to this shift. The same applies to the aperture element 56, which is also deflected through the supporting element 30's supporting element 60. Only the aperture element 57 does not change its position during the shift, so that the corresponding breakthrough 32 is closed by the aperture element 57.In contrast, the aperture element 56 does not change its position relative to the resting position (Fig. 5a) so that the aperture element 56's aperture 32 is pushed in front of the aperture element 56 and closed by it. This shows that, depending on the deflection of the supporting element 30, due to the force acting on the hair-holding elements during brushing or combing, part of the apertures alternately close or open and a targeted control of the direction of the outgoing air flow 52 is possible at certain sections.Force direction is being made.

For example, the support element 30 is fixed to the housing 12 by means of a locking device, which allows a switch-pusher with a cam attached to the housing 12 to be inserted into a nut attached to the support element 30 to prevent the support element 30 from turning.

A third embodiment of the invention is shown in Figures 6 and 7. The brush 28 is again formed by the supporting element 30 which has 32 breaks and on which the side of the air outlet 16 is facing the other side carries hair-capture elements 34 in the form of brushes or zinc. The aperture device 36 consists of a lens 64 fixed to the housing 12 and at least two independently moving lens elements 65, 66. The lens 64 consists of four longitudinal arches which form a grid 67 for the air outlet 16 . A total of 64 more or fewer longitudinal arches are possible, depending on the extent to which a stream of air is blown through the lens. The individual lens elements 64 are connected by two interconnected lens elements 65, 75, 75, 75, 75, 75, 75, 75, 75, 75, 75, 75, 75, 75, 75, 75, 75, and 75, and the number of the lens elements is described in a more stable manner. The number of the lens elements is also described in the figure 65, which is the largest and most stable in the image.

The support element 30 preferably has four longitudinal holes 32 and is arranged, from a rest position by a pivot axis 38, by means of two bearings 40, 42 on the housing 12 of the device 10. In its rest position, which corresponds to the basic position, the support element 30 is stabilized by the spring element 74. The spring element 74 is fixed to the housing 12 and rests on it. The deflected ends of the spring element 74 act on the aperture elements 65, 66. The side elements 65, 66 are, according to the deflection of the support element 30, by the combination of the means of contact 68, 69 of the support element 30 and the means of contact 70, 71, 72, 73 of the 12 and, respectively, of the other aperture element 75, 77, 66 of the 77, The area of displacement is limited by the other dimensions of the movement.

During the resting position (Fig. 7a), all the breaks 32 are air-filled. If, for hair-forming, the device 10 is now immersed in the hair with the bristles or zinc and a light pressure is applied, the comb or brush movement will move the lens elements 65, 66 by means of the support element 30 alternately and oppositely with respect to the other support element 65, 66 according to the brush or compression direction. This is achieved by holding the support elements 68, 69 of the support element 30 behind the lens elements 65, 66.

In this version, the force exerted on the part of the headlamp, i.e. the supporting element 30, during the combed or combed operation and the resulting displacement of the headlamp element 66 close the air outlets of the grille 67 corresponding to the direction of displacement, so that each individual break 32 is passed through by air and the outgoing air stream can be directed specifically to specific hair areas. In this version, the force exerted on the headlamp element, i.e. the supporting element 30, during the combed or combed operation and the resulting displacement of the headlamp element 66 close the air outlets 32 in the direction of the combed or combed direction.

The support 30 is identical to the prescribed embodiments and is adjustable by means of a locking device on the housing 12, but can be removed for cleaning or replacement with other support elements, e.g. with a different number of breakages and/or variable brush parts.
