JPS6328719A - Air conditioner deodorizing device for automobile - Google Patents

Abstract

PURPOSE:To enable reduction of a noise and easy fitting and removal of a deodorizing agent by providing an open/close door at a position opposite to connection of a fresh air introduction duct formed in a cowl box and an airconditioning device, and fitting the deodorizing agent to the inside of the door in such a way as to be freely detachable. CONSTITUTION:Fresh air introduced from a fresh air inlet 3 passes through a cowl box 2 and enters an airconditioning device 5 via a fresh air diffuser 4, a fresh air introduction inlet 7 and an intake unit 6. In this case, the air is deodorized by a deodorizing agent 15. And fitting and removal of the deodorizing agent 15 are done by opening a door 9. According to the aforesaid constitution, the deodorizing agent 15 as well works to prevent an increase in draft resistance and reduce a noise. Also, the deodorizing agent 15 can be easily fitted or removed.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an air conditioning deodorizing device for automobiles.

[Prior art]

As a conventional air conditioning deodorizing device for automobiles, Japanese Patent Application Laid-Open No. 58-7
There is something like the one shown in Publication No. 8821.

[Problems to be solved by the present invention]

However, according to this device, the deodorizer, which is a source of noise that causes ventilation resistance, is located in the vehicle interior, so the noise is high and it is difficult to attach and remove the deodorant.

Therefore, in view of such conventional examples, the present invention aims to reduce the noise of a deodorizing device and to facilitate the attachment and detachment of a deodorant.

[Means of the present invention]

In order to achieve such an object, the present invention connects an outside air inlet of an intake unit of an air conditioner to an outside air outlet of a front vehicle body structure in the form of an outside air guide duct having an outside air intake. An opening/closing door is provided on the facing surface of the vehicle body structure, and a deodorizer is removably installed on the inner wall of the opening/closing door.

[For production]

Therefore, according to the present invention, when the air conditioner is set to the outside air circulation mode and the vehicle is driven or the blower is turned on, outside air is drawn from the outside air intake, passes through the outside air guide duct, and enters the outside air introduction port of the intake unit. The wind flows. During this flow, the volatile components of the deodorizer on the inner wall of the opening/closing door installed opposite the outside air outlet are simultaneously inhaled.
Can deodorize air conditioners. Furthermore, when the deodorant becomes less effective, the door can be opened from the outside of the vehicle and the deodorizer replaced.

〔Example〕

FIG. 1 and FIG. 2 are diagrams showing one embodiment of the present invention.

In the figure, 1 is a car body, and a cowl box 2, which is a front body structure, is formed in the shape of an outside air guide duct, and has an outside air intake 3 on the upper surface 8, and an outside air outlet at a position shifted from left to right. It has 4. The outside air outlet 4 is provided with an air conditioner 5.
The outside air introduction lower of the intake unit 6, which has an internal/external air switching door and a blower (both not shown), is connected to the opening lO of the upper surface 8 of the vehicle body structure facing the outside air outlet 4. A housing section 14 having a slit 12 is formed in the inner wall 13 of the door 9, and a deodorant 15 is removably installed in the housing section 14. Since the heater unit and the like of the air conditioner 5 are well known, explanations and illustrations thereof have been omitted.

16 is an instrument panel.

With this configuration, by setting the mode of the control plate (not shown) to outside air introduction,
The inside/outside air switching door provided in the intake unit 1-6 opens the outside air introduction port. Next, outside air is introduced from the outside air intake port 3 by the ram pressure generated by running the car or by turning the blower (not shown) in the intake unit 6, and passes through the cowl box 2, which is an outside air guide duct. and the outside air inlet 7 of the intake unit 6.
Fukou 8 is played. During this flow, the volatile components of the deodorant 15 are simultaneously sucked in, so that the air conditioner 2 and 5 can be deodorized. Furthermore, if the effectiveness of the deodorant 15 has decreased, the door 9 may be opened from the outside of the vehicle and the deodorant 15 may be replaced.

〔effect〕

As described above, according to the present invention, the deodorant air freshener, which is a source of ventilation resistance and noise, is located outside the vehicle interior, so it is far away inside the vehicle interior and becomes quiet.

Furthermore, vibrations are damped by the dampers, dash insulators, carpets, etc. installed in the interior and exterior of the vehicle, which has the effect of further attenuating the noise.
