Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a vehicle air conditioner filter used in a vehicle air conditioner.

[0002]

[Prior Art]

 Generally, a vehicle is equipped with an air conditioner for cooling or heating the interior of the vehicle. This air conditioner is a blower unit that is a blower for a vehicle, a cooler unit for cooling, and a vehicle air conditioner that is installed immediately before this cooler unit and removes dust and the like contained in the air blown from the blower unit. It is equipped with a filter and a heater unit that performs heating (for example, Japanese Utility Model Laid-Open No. Sho 60-32118).

In such an air conditioner, the air discharged from the blower unit passes through a cooler unit after being filtered by a vehicle air conditioning filter, then passes through a heater unit, and then is supplied into the vehicle from a defroster or the like. It At this time, warm air is obtained by operating only the heater unit to heat the vehicle interior, or cold air is obtained by operating only the cooler unit to cool the vehicle interior.

[0004]

[Problems to be solved by the device]

 By the way, in a vehicle in which the air conditioner is not equipped with a cooler unit, the duct diameter of the portion corresponding to the evaporator portion of the cooler unit is usually reduced. However, if the same air conditioning filter as the vehicle air conditioning filter installed in the cooler unit is to be installed in the air conditioning system of the vehicle not equipped with the cooler unit, the duct diameter must be increased and the duct The seal becomes complicated.

In addition, since the vehicle air-conditioning filter installed immediately before the cooler unit is installed near the evaporator, it is cooled by the evaporator, which causes moisture to adhere to the vehicle air-conditioning filter, causing odor. easy.

An object of the present invention is to provide a vehicular air-conditioning filter that solves the above-mentioned problems of the conventional technology and that is easy to replace the filter.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the vehicle air conditioning filter of the present invention is a filter material that is folded in a wave shape, and forms a ring-shaped cylindrical body that can be housed inside the ring-shaped blower fan of the blower unit. Moreover, when the filter material is stored in the blower fan, the corrugated protrusions are arranged between the blades.

[0008]

[Action]

 The vehicle air-conditioning filter of the present invention uses the filter material formed in the shape of an annular cylinder so that the corrugated protruding portions are arranged between the blades, so that the cooling / heating can be performed without modifying other portions. You can share it.

[0009]

【Example】

 An embodiment according to the present invention will be described below with reference to the drawings.

First, the overall configuration of the present embodiment will be described with reference to FIGS. 1 to 4. In FIG. 1, the blower fan 1 has an annular cylindrical shape, and its peripheral wall portion is formed by a large number of blades 3. This blower fan 1 has an annular shape by fixing one of the blades 3 at a constant interval to a circular ring portion 7 which is formed by radially projecting the bottom of the truncated cone 5 and fixing a fixing ring 9 to the other side of the blade 3. It becomes cylindrical. The circular ring portion 7 is provided with fixing holes 11 at regular intervals. A fixed portion 15 for the motor rotating shaft is provided at the center of the circle on the upper surface 13 of the truncated cone 5.

The vehicle air-conditioning filter 17 has a ring-shaped cylindrical body made of a filter material 19 having a size that can be stored inside the ring-shaped cylindrical shape of the blower fan 1. The corrugated projecting portion 20 of the filter material 19 having a width substantially equal to the length of is formed in a corrugated shape so as to be housed between the blades 3 as shown in the drawing. Both ends of the filter material 19 are fixed by fixing rings 21 and 23. Fixing pins 25 are provided on the fixing ring 21 at the same intervals as the fixing holes 11. On the fixing ring 23, fixing hooks 27 that are attached to and detached from the fixing ring 9 are provided at regular intervals.

Next, a method of using this embodiment will be described.

First, a blower motor (not shown) is removed, and the vehicle air conditioning filter 17 is housed from the opening surface of the blower fan 1. At this time, the fixing pin 25 of the fixing ring 21 of the vehicle air-conditioning filter 17 is housed in the fixing hole 11 of the blower fan 1, and the protruding portion 20 of the filter material 19 is inserted between the blades 3. Then, the fixing hook 27 of the fixing ring 23 of the vehicle air conditioning filter 17 is hooked and fixed to the fixing ring 9 of the blower fan 1. By doing so, the vehicle air conditioning filter 17 is fixed inside the blower fan 1. Then, by fixing the blower motor, the blower fan 1 to which the vehicle air conditioning filter 17 is attached is installed. As a result, the vehicle air conditioning filter 17 does not come off from the blower fan 1 even if the blower motor is stopped.

When the blower fan 1 is rotated in the direction of the arrow R in the figure in such a fixed state, the vehicle air-conditioning filter 17 also rotates together with the blower fan 1. Therefore, as shown in FIG. The force collects on the protruding portion 20 of the filter material 19.

Therefore, according to the above-described embodiment, since foreign matter collects at the tip of the vehicle air conditioning filter 17, it is possible to prevent clogging of other portions, and therefore the life of the vehicle air conditioning filter 17 is reduced. It can be postponed. Furthermore, since the vehicle air conditioning filter 17 can be easily attached and detached by removing the attachment screw of the blower motor, the replaceability of the vehicle air conditioning filter 17 is improved. Further, according to the present embodiment, the vehicle air-conditioning filter 17 functions as the blower fan 1, so that the motor efficiency is improved and the heating vehicle and the cooling vehicle can be commonly used. Moreover, since there is no risk of generation of water or the like, there is no fear of producing an offensive odor.

[0016]

[Effect of the device]

 As described above, according to the present invention, since the vehicle air conditioning filter can be attached to and detached from the blower fan, the replaceability of the vehicle air conditioning filter is improved and the cooler is applied to the vehicle having only the heater unit. When the unit is installed, it has the effect that it can be used without modification of other parts.
