Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an intake unit structure for an air conditioner for a motor vehicle, which allows an air purifying function to be added freely without structural changes.

Conventional technology Conventionally, the structure shown in Figure 3.4 has been put into practical use as an intake unit for an automatic air conditioner. -14), see page ■-79). In other words, this intake door! '1 k”L, casing 2
A similar air inlet 3, an outside air inlet 4, and an air outlet 5 are formed in the casing 2, and an intake door 6 is pivotally supported at the base of the outside air inlet 3.4. It's been a long time. A pro fan 8 using the motor 7 as a driving source is disposed in the casing 21F3, and a bell mouth 9 is disposed upstream of the pro fan 8. An opening 10 is formed in a portion of the bell mouth 9 that faces the proafan 8, and a seven flange 11 that extends vertically in a curved manner is formed at the periphery of the opening 100.

In this structure, when the proa fan 8 rotates, air is introduced into the casing 2 from the inside air inlet 3 or the outside air inlet 4, and the air passes through the opening 10 to the air outlet 5.
The air is then fed to a cooling unit (not shown).

On the other hand, in today's car, an intake unit 12 as shown in Fig. 5.6 has been proposed to perform not only air conditioning and heating in the passenger compartment but also air purification (1987).
In other words, in this intake unit 12, the interior of the housing 13 is separated by a partition wall 14 into a first chamber 16 having an outside air inlet 15 and a second chamber having an air outlet 17. room 18
A filter 19.20 is disposed in each chamber 18.18. In such a structure,
The purified air that is introduced into the first chamber 16 as the filter rotates 80 times is purified as it passes through the filter 19, and then sent to the second chamber 18. After being purified again by the filter 20, the air It is fed to other units through the outlet 17.

Problems to be Solved by the Invention However, in automobiles, it is common practice to set multiple specifications with different roadways within the same vehicle type, and for advanced specification vehicles, the 5th grade The intake unit 12 equipped with an air purifier such as the filter 19 or 20 shown in Figure 6 was adopted, and relatively popular specification cars were equipped with only the air blowing function shown in Figure 3.4. It is assumed that intake unit 1 will be adopted. At this time, since the external shapes of both units) 1 and 12 are significantly different based on the difference in the structure of the same parts, each unit) 1.
The structure of the peripheral member to which the unit 12 is attached, such as the lower structure of the high instrument panel, etc., differs depending on each unit 1.12.

For this reason, regarding parts common to each specification of the same car model,
Although the common use of "citcit" is advantageous in terms of manufacturing costs, it is necessary to separately mold the peripheral members for each specification I strawberry, which has the disadvantage of inevitably increasing costs.

The present invention has been made with attention to such conventional problems, and it is possible to add an air purification function as necessary without making any structural changes. It provides a unit structure.

Next Means for Solving the Problems In order to solve the above-mentioned problems, in the present invention, a blower fan is housed in a casing having an air inlet and an air outlet, and the blower fan of the casing circle is In an intake unit of an automatic heavy-duty air conditioner having a bell mouth disposed on the downstream side, an air purifying member is removably attached to an opening of the bell mouth via an adapter.

Effect In the above configuration, relatively popular spec cars within the same car model adopt an intake unit that only has an air blowing function without installing an air purifying member, and in high grade spec cars, An intake unit equipped with an air purifying member and having both a blowing function and an air purifying function is adopted. At this time, since the air purifying member is removably attached to the opening of the bell mouth via an adapter, by attaching and detaching the air purifying member along with the adapter as necessary, the intake unit of the same structure can be installed from both companies. Therefore, the intake unit itself and its surrounding parts can be used in common for various specifications.

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

That is, as already described with reference to FIG. 3.4, the intake unit 1 has a casing 2, and the casing 2
There is an internal air inlet 3. An air outlet 5 is formed which communicates with the outside air inlet 4 and a cooling unit (not shown), and an intake door 6 is pivotally supported at the base of the inside and outside air inlet 3.4. A pro fan 8 whose driving source is a motor 7 is disposed in one circle of the casing, and a bell mouth 9 is disposed upstream of the pro a fan 8 . A circular opening 10 is formed in a portion of the bell mouth 9 that faces the proafan 8, and seven langes 11 are provided at the periphery of the opening 10 in a curved manner.
is formed. - As shown in FIG. 1, the adapter 21 has a shape along the inner circumference of the opening 100.
2, the inner circumference of the rim 22 is bridged with a plurality of orthogonal crosspieces 23, and the upper surface of the steel structure 23 has an air purifying function that fits into the inner circumference of the rim 22. A filter 24 is placed thereon. Further, on the outer circumferential portion of the rim 22, a locking piece 21 having a shape along the surface of the seven flange 11 is provided at opposing portions.
5.2Fi is formed at the lower end of the locking piece 25.25.
is formed.

In this embodiment with the above configuration, the same! For the relatively popular specification I within m, we adopted the intake unit 1 having only the ventilation function without the adapter 21 and filter 24 installed, as shown in Fig. 3.4. Assemble.

In addition, in the case of high-grade specification cars in the same army 1, as shown in FIG. The claws 26 and 26 are engaged with the lower edge of the flange 11, and the filter 24 is fitted onto the inner circumference of the rim 22 on the crosspiece 23. In this way, the τ filter 24 is inserted through the adapter 21. The installed intake unit 1 is assembled into the specified vehicle.

At this time, since the adapter 21 and the filter 24 are attached to the bell mouth 9, which is an existing member of the intake unit 1, it is possible to optionally install the adapter 21 and the filter 24 without changing the structure of the intake unit itself as shown in FIGS. 3 and 4. It can be attached to. Next, the intake unit 1 having the same structure can be shared between a popular specification car and a high-end specification car, and by sharing the intake unit 1, it becomes possible to reduce manufacturing costs. Furthermore, since the adapter 21 and the filter 24 are attached to the bell mouth 9 inside the casing 2, the adapter 21 and the filter 24 are
1. The external shape of the intake unit 1 does not change due to the installation of the filter 24 members, and the shape of the external part of the intake unit 1 adopted in each of the specification cars is the same.

To be careful, the structure of the surrounding parts of the intake unit 1, such as the lower structure of the instrument panel, is the same in each of the above specification cars, and not only the intake unit 1 but also the surrounding parts can be used in common. Significant cost reductions are possible. Caloete Suki Adapter 21
&'! Since it can be installed without changing the structure of the bell mouth 9, the "c filter 24 can also be installed in the intake unit 1 mounted on an existing vehicle via the adapter 21.

In the above embodiment, C. By engaging the locking pieces 25, 25 formed on the rim 22 with the flange 11,
Although the adapter 21 can be attached with one touch, it is also possible to screw the adapter 21 to the periphery of the opening 10, and the air purifying member is not limited to the filter 24, but can also be used to remove unpleasant components in the air, Deodorizers, fragrances, etc. can be used as appropriate, as long as they can reduce the amount.

DETAILED DESCRIPTION OF THE INVENTION According to the present invention, an air purifying member is detachably attached to an opening of a bell mouth disposed within an intake unit via an adapter. Therefore, in places where multiple specifications 1 are set within the same Arashi type, by attaching an air purifying member along with an adapter according to the specifications, it is possible to change the structure of the intake unit that only has an air blowing function. It is possible to add air purification function without having to do so. Therefore, not only can the same intake unit be shared among multiple production specifications, but also the surrounding parts of the intake unit can be shared, and manufacturing costs can be reduced by sharing parts between each specification. It is something that can be done.
