Description

Description: TECHNICAL FIELD The present invention relates to an air blower for an automobile, and more particularly to an automotive air conditioner having a deodorizing function member such as a deodorant / aromatic material and used for an air conditioner for an automobile. The present invention relates to a blower and an air conditioner for a vehicle.

[Conventional technology]

A conventional air conditioner for a vehicle equipped with a deodorizing device or a fragrance device (hereinafter collectively referred to as a deodorizing device) includes a separate unit type in which the deodorizing device is incorporated into the air conditioning device as a separate unit and controlled, and an air conditioning device. 2 with the existing unit use type incorporated as a part of the unit to be configured
There are two types. For the former type, for example,
−32645, Shokai 61-105215 to 105217, Shokai 1-14561
7, actual opening 63-130312, actual opening Hei 2-219, actual opening Hei 2-661
3, there are Japanese Utility Model Application Laid-Open Nos. 62-118722, and the latter type includes, for example, Japanese Utility Model Application Laid-Open No. 63-130311, Japanese Utility Model Application No. 63-192115, Japanese Utility Model Application No.
-131611 and JP-A-1-215616.

The following three conditions can be considered for the condition of the deodorizing device incorporated in the air conditioner from the viewpoint of deodorizing and aroma.
It is best to have all three conditions.

Achieving the purpose regardless of the operation of the air conditioner and the control mode (reliable functionality).

It has a removable structure that can be easily replaced when it loses its deodorizing effect, and is built into the air conditioner (easiness of replacement).

Have economics according to the purpose and have excellent productivity (economic and productivity).

On the other hand, since the former type of the conventional example is a separate unit, most have extremely complicated control means for turning on and off in the full control mode which is the first condition, and at the same time, have the third type. There is a defect that does not satisfy the conditions. Further, some of them have pipes, branch distribution ducts, and the like when incorporated in the air passage, and therefore, once incorporated, have an improvement that the second condition is not satisfied.

In addition, among the former types, in particular, Japanese Utility Model 62-118722,
Since the deodorant storage case is attached to the lower extension of the cover surrounding the fan of the blower, complicated control means is not required, and the mounting position of the deodorant storage case is based on the accelerated flow formed by the fan. Because it is far away, the deodorizing effect is not only small, but also the air passage changes due to opening and closing of the opening and closing damper, so that when the opening and closing damper of the lower extension of the cover is opened, the air flow will bypass the deodorant material After all, there is a problem that the first condition is not completely satisfied. There is also a disadvantage that the second condition is not satisfied because of the installation of the extension cover.

On the other hand, the latter type of the conventional example satisfies the third condition because its configuration is relatively simpler than the former type, but on the other hand, the position where the deodorizing device is provided always becomes the position where the air passage becomes. Depending on the control mode, there is a case where the deodorizing function cannot be exhibited, and since the installation position is fixed, the replacement is not easy, and as a result, the first and second conditions are not satisfied.

Among the latter types, in particular, JP-A-1-215616
The first and third conditions are satisfied because the deodorizing device is installed on the inner periphery of the blower (fan) using the existing configuration, but when the deodorizing effect is lost, After removing the blower main body, it is necessary to remove and replace the blades of the electric motor, and there is a problem that the second condition is not satisfied. Further, in this conventional technique, since the location of the deodorizing device is inside the blade, the opening area of the deodorizing member is limited with respect to the air passage surface, which is not sufficient to maximize the deodorizing effect. Point.

[Problems to be solved by the invention]

As described above, there is a problem that none of the conventional deodorizing devices can satisfy all of the above-mentioned conditions that the deodorizing device incorporated in the air conditioner should have.

An object of the present invention is to solve the advantages and disadvantages of the deodorizing device of the prior art, and to provide an air blowing device for an automobile and an air conditioning device for an automobile that satisfy all of the conditions to be provided as a deodorizing device for an automotive air conditioner as much as possible. It is in.
