 An embodiment of the present invention will be described in detail below with reference to the drawings. (First Embodiment) The drawing shows an auxiliary structure for a vehicle air conditioner. First, the structure of the vehicle air conditioner will be described. In Fig. 1, an inside air / outside air switching box 3 having an outside air intake 1 and an inside air intake 2 is shown. The inside / outside air switching box 3 is provided with a fan 5 as a blower driven by a blower motor 4, and an inside / outside air switching door 6 is provided as an inside / outside air switching means for selecting intake of conditioned air. ing.

A cooler unit 9 is arranged at the next stage of the blower unit 7 configured as above via a communication duct 8. The cooler unit 9 includes an evaporator 11 as a heat exchanger in a cooler housing 10.

The above-mentioned evaporator 11 is an evaporator connected to the refrigeration cycle and has an effect of removing heat from the surroundings.

A heater control unit 12 is connected to the next stage of the cooler unit 9 described above. The heater control unit 12 has a heater core, an air mix door, a vent door, a defroster door, a heat door, and a mixing chamber therein, and outputs the blown air (cool air and hot air) that has been air-conditioned by switching the above-mentioned doors. It is configured to blow out from the froster outlet, the vent outlet, and the heat outlet to the necessary places in the vehicle interior.

In the vehicle air conditioner configured as described above, as an example of the air conditioning air flow path, the communication duct 8 located at the intermediate portion between the inside / outside air switching box 3 and the cooler housing 10 and on the upstream side of the evaporator 11 is described. Disposes the solid solvent 15 through a holder 14 having a flange 13 as a solvent holding means. The holder 14 and the solid solvent 15 may be pre-assembled at the time of manufacturing the vehicle, or may be retrofitted after the vehicle is manufactured. However, in consideration of the replacement of the solid solvent 15, the holder 14 described above is fitted. It is desirable to attach them detachably by means such as means, pressure means, clip fastening means, screw fastening means and the like.

As the solid solvent 15 described above, a solid solvent having a single action or a complex action of aroma, deodorization, deodorization, deodorization, disinfection, antibacterial or antifungal is used, for example, in the shape of a cylinder. The shape is not limited to the cylindrical shape, and may be a quadrangular prism shape, a polygonal pillar shape, a non-cylindrical shape, or the like.

As described above, since the solid solvent 15 having the above-mentioned simple substance action or the complex action is held in the holder 14 and disposed in the air conditioning air path, the internal elements (evaporator 11, various doors and heater core) of the vehicle air conditioner are arranged. Etc.) can be naturally deodorized, deodorized, deodorized, sterilized, antibacterial or antifungal treated or released aroma components into the passenger compartment without any human intervention to obtain aroma effects. As a result, there is an effect that the vehicle interior environment can be sufficiently improved.

Further, since the above-mentioned solid solvent 15 is arranged on the upstream side of the evaporator 11 in the air-conditioning air path, at least the evaporator 11 and the internal elements (various doors and heater cores) of the air-conditioning apparatus on the downstream side thereof are deodorized. Deodorizing, deodorizing, sterilizing, antibacterial or antifungal effects can be naturally obtained by using air conditioning air.

In the embodiment shown in FIG. 1, the single solid solvent 15 is arranged in the 8 communicating ducts upstream of the evaporator 11, but the switching locus α of the inside / outside air switching door 6 other than this portion is set. It may be arranged in the inside / outside air switching box 3 so as not to interfere with the above, or plural solid solvents 15 may be arranged in plural places. Further, in FIG. 1, the single solid solvent 15 is disposed from the lower side to the upper side, but it may be disposed laterally from the outer side to the inner side of the vehicle air conditioner. If the above solid solvent 15 is arranged upstream of the fan 5 so as not to interfere with the fan 5 and the inside / outside air switching door 6, even if the fan blade having a complicated shape of the fan 5 is deodorized and deodorized, It is possible to obtain the effect of deodorization, sterilization, antibacterial or antifungal treatment alone or in combination, and the fragrance effect can be secured as described above.

(Second Embodiment) FIG. 2 shows another embodiment of the auxiliary structure for a vehicle air conditioner. In the previous embodiment, a vehicle air conditioner of the type in which the fan 5 is arranged upstream of the evaporator 11 is shown. However, this embodiment shown in FIG. 2 is applied to a vehicle air conditioner of the type in which the fan 5 is arranged downstream of the evaporator 11.

In this case, the side surface of the inside / outside air switching box 3 is directed laterally inward from the outside of the inside / outside air switching box 3 so as to face the front surface of the evaporator 11 and not interfere with the switching locus α of the inside / outside air switching door 6. The solid solvent 15 and the holder 14 described above are attached.

In FIG. 2, reference numeral 16 is an aerodynamic door, 17 is a heater core, 18 is a differential / heater / cooler switching door, 19 is a heater / cooler switching door, 20 is a heater outlet, 21 is a cooler outlet, and 22 is a differential blower. It is the exit.

Even if configured in this manner, the same operation and effect as those of the previous embodiment can be obtained. Therefore, in FIG. 2, the same parts as those in FIG. 1 are designated by the same reference numerals, and detailed description thereof will be omitted. If the above-mentioned solid solvent 15 is in the air-conditioning air path, for example, it is arranged on the downstream side of the evaporator 11 to deodorize the fan 5 and the vehicle air-conditioning system elements (including the inner wall) on the downstream side thereof. It may be configured for deodorization, deodorization, sterilization, antibacterial or antifungal treatment.

(Third Embodiment) FIGS. 3 to 6 show still another embodiment of an auxiliary structure for a vehicle air conditioner. In this embodiment, a solid solvent formed by extending the holder 14 is formed. 15 A cylindrical inner cylinder 24 with a top deck 23 for surrounding is provided, and a cylindrical outer cylinder 25 is provided which rotates along the outer peripheral surface of the inner cylinder 24, and the outer cylinder 25 receives conditioned air. The displacing wind plate 26 is integrally formed.

Further, the support shaft 27 integrally formed at the center of the lower surface of the top deck 25a of the outer cylinder 25 is provided so as to project below the central hole in the top deck 23 of the inner cylinder 24, and the projection portion and the inner portion. A return spring 28 made of a spiral leaf spring (flat spiral spring) is provided between the cylinder 24 and the air blower plate 26 and the outer cylinder 25 in order to restore the normal state shown in FIGS. 3 and 4. I am configuring.

Furthermore, at least one triangular shape that matches the inside and outside in the normal state is provided on the downstream side surfaces of the inner cylinder 24 and the outer cylinder 25 facing the evaporator 11 (see FIG. 1). The openings 29 and 30 (two are illustrated in this embodiment) are formed.

When the air-conditioning air volume or air-conditioning air pressure flowing through the communication duct 8 is small, the openings 29 and 30 are aligned with each other by the action of the return spring 28 as shown in FIGS. As shown in FIG. 5 and FIG. 6, as the air-conditioning air volume or air-conditioning air pressure flowing through the 8 parts of the communication duct increases, the wind-receiving plate 26 and the outer cylinder are resisted against the return spring 28. 25 rotates in the downstream direction of the conditioned air (clockwise direction in FIG. 5), the opening 29 on the inner cylinder 24 side is sequentially closed by the opening 30 on the outer cylinder 25 side, and the opening communication area is reduced. The emission amount control mechanism 31 is configured so that the emission amount from the solid solvent 15 is gradually reduced to be relatively small. 5 and 6 exemplify the state of the maximum air conditioning air flow or the maximum air conditioning air pressure.

With this configuration, the divergence amount control mechanism 31 described above reduces the divergence amount from the solid solvent 15 as the conditioned air volume or conditioned air pressure increases, and thus the durability of the solid solvent 15 is improved. Therefore, there is an effect that the so-called solid solvent 15 can be made to last longer.

Further, since the air receiving plate 26 that is displaced by the conditioned air is provided, the amount of divergence can be controlled by the mechanical displacement of the air receiving plate 26. In other words, since the air-conditioning air itself is effectively used as a divergence amount control source, the structure of the divergence amount control mechanism 31 can be simplified. Furthermore, since each of the elements 23 to 31 is assembled to the holder 14 with the flange 13, the assembling property can be improved.

The embodiment shown in FIGS. 3 to 6 has substantially the same operation and effect as those of the previous embodiment in other points. Therefore, in FIGS. The same reference numerals are given and detailed description thereof is omitted.

(Fourth Embodiment) FIG. 7 shows still another embodiment of an auxiliary structure for a vehicle air conditioner. In this embodiment, protection of the solid solvent 15 formed by extending the above-mentioned holder 14 is carried out. The guide cylinder 32 for use is provided, and at least one opening 33 1 is formed on the leeward side of the guide cylinder 32.

A support shaft 34 is provided on the flange 13 of the holder 14, and a baffle plate 35 is pivotally attached to the support shaft 34. This wind receiving plate 35 is spring-biased by the return spring 36 to the position shown by the solid line in FIG. 7, and when the air-conditioning air volume or air-conditioning air pressure flowing through the communication duct 8 (see the previous figure) is small, it returns as shown by the solid line in the figure. By using the spring 36, the opening / closing piece 37, which is integrated with the air blower plate 35, is separated from the opening 33, so that the solid solution 15 has a relatively large amount of divergence, and the amount of air conditioning flowing through the communication duct portion is also small. As the air conditioning air pressure increases, the wind receiving plate 35 and the opening / closing piece 37 are rotated clockwise in the figure against the return spring 36 as shown by the phantom line in FIG. The portion 33 is sequentially closed to form a divergence amount control mechanism 38 in which the divergence amount from the solid solvent 15 is relatively small.

By assembling the above-mentioned elements 32 to 38 into the holder 14 with the flange 13 in this way, the divergence amount control effect can be obtained while improving the assembling property. In other respects, since the same operation and effect as those of the previous embodiment shown in FIGS. 3 to 6 are achieved in other points, the same parts in FIG. And a detailed description thereof will be omitted.

(Fifth Embodiment) FIG. 8 shows still another embodiment of the auxiliary structure for a vehicle air conditioner. In this embodiment, a substantially wapper shape is formed on the above-mentioned flange 13 via a bimetal clamper 39. A bimetal 40 is attached, and the bimetal 40 is configured to surround and surround the solid solvent 15, and an opening 41 formed between both ends of the bimetal 40 is located on the leeward side of the solid solution 15. .

When the air conditioning airflow in the portion where the solid solvent 15 is disposed is low, the opening area of the opening 41 by the bimetal 40 becomes relatively wide as shown by the solid line in FIG. 8, and the air conditioning airflow in that portion is high. As shown in FIG. 8, the opening area of the opening 41 formed by the bimetal 40 is relatively narrowed as shown by the phantom line in FIG. 8 to form a divergence amount control mechanism 42 that reduces the divergence amount from the solid solvent 15. .

By assembling the holder 14 with the flange 13 by the above-described respective elements 39 to 42 in this way, the divergence amount control effect can be secured while improving the assembling property. Moreover, the divergence amount control mechanism 42 reduces the divergence amount from the solid solvent 15 as the temperature of the conditioned air increases, so that the durability of the solid solvent 15 is increased and the so-called solid solvent is made to last longer. There is an effect that can be.

Further, since the divergence amount control mechanism 42 is configured by using the bimetal 40, the temperature of the conditioned air is effectively used as a divergence amount control source, and the divergence amount according to the displacement of two metal plates having different thermal expansion coefficients. Therefore, there is an effect that the structure of the divergence amount control mechanism 42 can be simplified.

Even with such a configuration, the other points have substantially the same operation and effect as those of the previous embodiment. Therefore, in FIG. 8, the same parts as those in the previous figure are designated by the same reference numerals, and Although detailed description is omitted, in the embodiment of FIG. 8, the guide tube 32 already shown in FIG. 7 is attached to the outside of the solid solvent 15, and the opening 33 of the guide tube 32 is opened and closed by the bimetal 40 described above. Of course, it may be configured.

In the correspondence between the configuration of the present invention and the above-mentioned embodiment, the solvent holding means of the present invention corresponds to the holder 14 of the embodiment, and similarly, the air-conditioning air flow path is from the air-conditioning air intake port to the air-conditioning air intake port. The heat exchanger corresponds to the path to the air outlet, the evaporator 11 corresponds to the evaporator 11, and the divergence amount control means corresponds to the divergence amount control mechanisms 31, 38 and 42. It is not limited to only.

For example, according to the third aspect, an air pressure detection sensor for detecting the air pressure of the conditioned air is provided, and the emission amount from the solid solvent 15 is reduced as the air pressure increases due to the sensor output. It may be an electronically controlled type divergence amount control means in which the outer cylinder 25 without the air receiving plate 26 is driven by a motor.

Further, in claim 5, the inner cylinder 24 and the outer cylinder 25 without the air receiving plate 26 are used in place of the bimetal, and a temperature sensor for detecting the temperature of the conditioned air is provided. It is also possible to use an electronically controlled divergence amount control means for driving the outer cylinder 25 so that the divergence amount from the solid solvent 15 becomes smaller as the temperature rises.
