Abstract

PURPOSE:To prevent leak of air due to incomplete mounting in a structure for mounting a cooling unit between a blower unit and a heater unit by making a mounting bracket or body side bracket horizontally rotatable so as to permit horizontal rotation of the whole cooling unit. CONSTITUTION:When a cooling unit 23 is inserted between a blower unit 2 and a heater unit 4, only the portion forming an air inlet 13 comes in abutment against a guide flange 16 and a side surface 19 of the blower unit 2, and only a sealing material 21 of the air inlet 13 is compressed. Then, the reacting force of the sealing material 21 causes the whole cooling unit 23 to be horizontally rotated around a rotating shaft 27 in the direction A, so that communication is completed between an air outlet 12 of the blower unit 2 and an air inlet 15 of the heater unit 4 in an inclined manner with no gap therebetween. This structure assures mounting with no leak of air, despite of misregistration between the blower unit and the heater unit.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a mounting structure for a cooling unit in an air conditioner.

[Conventional technology]

Examples of conventional cooling unit installation structures include those shown in Figures 9 to 11 [Bluebird (U11 type) air conditioner installation procedure manual (for C and A spinning wheels) August 1984 (Japanese) Published by Radiator) No. 10
See page]. As shown in FIG. 11, the air conditioning system W1 for an automobile is comprised of a blower unit 2 that pumps air, a cooling unit 3 that cools the air, and a heater unit 4 that warms the air and adjusts it to an appropriate temperature. . The cooling unit 3 in this air conditioner 1 is
There are so-called air conditioner-equipped cars that are installed on the car from the beginning and those that are installed on the car later. In an automobile in which the cooling unit 3 is not installed from the beginning, the blower unit 2 and the heater unit 4 are connected by a flexible duct or the like (not shown). When installing the cooling unit 3 later, insert the cooling unit 3 into the instrument panel 7 through the working opening 6 formed in the back wall of the glove box 5, and first connect the space between the blower unit 2 and heater unit 4. The connected flexible duct etc. are removed and the cooling unit 3 is installed in its place. In this air conditioner 1, the blower unit 2 is positioned and fixed to a vehicle body panel near the cowl, and the heater unit 4 is positioned and fixed to a floor panel. An inclined mounting bracket 9 is provided on the upper surface 8 of the cooling unit 3, and a vehicle body side bracket 10 for mounting the cooling unit 3 is provided above between the blower unit 2 and the heater unit 4 in a corresponding manner. It is set up. By fixing the mounting bracket 9 to the vehicle body side bracket 10 with screws 11, the entire cooling unit 3 is positioned and fixed between the blower unit 2 and the heater unit 4. By installing the cooling unit 3 in this way, the air outlet 12 of the blower unit 2 and the air outlet 13 of the cooling unit 3 are connected, and the air outlet 14 of the cooling unit 3 and the air outlet 15 of the heater unit 4 are connected. Therefore, a continuous air flow path is formed within the air conditioner 1. Moreover, the air outlet 12 of the opposing blower unit 2
And in the back part of the air population 15 of the heater unit 4,
Guide flanges 16 and 17 are formed to protrude so as to face each other, and are used to receive and hold the cooling unit 3 inserted between the blower unit 2 and the heater unit 4 in a proper position for installation. Guide flanges 18.18 are also formed on the front side of the air ports 13 and air outlet 14 on both sides of the cooling unit 3, and when the cooling unit 3 is fixed in the normal position, the guide flanges 18.18 is blower unit 2
and the side surfaces 19 and 20 of the heater unit 4, respectively. In addition, elastic sealing materials 21 and 22 are applied to the peripheries of the air port 13 and the air outlet 14 of the cooling unit 3 to improve the airtightness of the connection portion.

[Problems to be solved by the invention]

However, in such a conventional cooling unit mounting structure, the cooling unit 3 was simply fixed by screws 11 between the mounting bracket 9 and the vehicle body side bracket 10, so that the blower unit 2 and heater unit 4 were not properly connected. If the heater unit 4 is installed out of position, for example, as shown in FIG.
If the cooling unit 3 is moved toward the back of the blower unit 2, even if you try to install the cooling unit 3 by inserting it between the blower unit 2 and the heater unit 4, the air population 13 of the cooling unit 3 will not be connected to the blower unit 2.
The guide flange 16 of the blower unit 2 contacts the guide flange 16 of the cooling unit 3 first and cannot be inserted any further. However, the air outlet 14 of the cooling unit 3
Between this and the air population 15 of the heater unit 4, a gap S corresponding to the amount of positional deviation is created on the back side and the front side, respectively, and the air inside the air conditioner 1 leaks from there. This will lead to a decrease in the performance of the harmonizing device 1. This invention was made by focusing on such conventional technology, and even if there is a misalignment in the mounting position between the blower unit and the heater unit, the cooling unit can be inserted between the blower unit and the heater unit without any gap. It is an object of the present invention to provide a mounting structure for a cooling unit that can be mounted.

[Means for Solving the Problems] In order to achieve the above object, in this invention, either the mounting bracket of the cooling unit or the vehicle body side bracket is made horizontally rotatable, and the entire cooling unit is made horizontally rotatable. [See FIGS. 1 to 5, which correspond to one embodiment of the present invention]. [Operation] The entire cooling unit can be installed in a horizontally rotatable state, so it can be used in situations where there is a misalignment between the blower unit and heater unit and a gap is created at the connecting part of the cooling unit. Also, the cooling unit rotates to close the gap, and the blower unit and heater unit can be reliably connected in a sealed state.

【Example】

Preferred embodiments of the present invention will be described below with reference to the drawings. Incidentally, the same reference numerals are given to the parts common to the conventional ones, and redundant explanation will be omitted. 1 to 5 are diagrams showing an embodiment of the present invention. The cooling unit 23 in this embodiment is provided with a horizontally rotatable mounting bracket 25 on its upper surface 24. This mounting bracket 25 is integrally provided upright on the upper surface portion 24 and is rotatably fitted into the rotary shaft 27, which has a split-tipped shape and has a non-return claw 26 formed at its tip. It consists of a screw fixing part 28. This screw fixing part 28 is made by fixing a fixing plate 30 provided with two screw holes 29 in an inclined manner to a cylindrical part 31. By fitting this cylindrical part 31 onto the rotating shaft 27, the whole can be rotated. It is horizontally rotatable relative to the moving shaft 27, and the check claw 26 engages with the upper end of the cylindrical portion 31 to prevent it from coming off. By fixing this mounting bracket 25 to the vehicle body side bracket 10 with screws 32, the entire cooling unit 23 can be mounted in a horizontally rotatable state. Therefore, similarly to the explanation of the conventional example, for example, the heater unit 4
is moved further back than blower unit 2 [4th
When the cooling unit 23 is inserted between the blower unit 2 and the heater unit 4 for installation, first, only the air outlet 13 side part is attached to the guide flange 16 and side surface 19 of the blower unit 2, respectively. come into contact with That is, only the elastic sealing material 21 of the air population 13 is compressed. Then, the air population 13 side of the cooling unit 23 is pushed back toward you by the reaction force of the compressed elastic sealing material 21, so that the cooling unit 23
The entire cooling unit 23 horizontally rotates in the direction of arrow A, and the entire cooling unit 23 is in an "oblique state" to connect the air outlet 12 of the blower unit 2 and the air outlet 15 of the heater unit 4 without any gaps. [See Figure 5]. In other words, when the cooling unit 23 is inserted, there is a gap between the air outlet 14 of the cooling unit 23 and the air outlet 15 of the heater unit 4, but as the entire cooling unit 23 rotates horizontally, Since the side portions abut against the guide flange 17 and the front side portions of the elastic sealing material 22 abut against the side surfaces 20 of the heater unit 4, no gap is left as is. FIG. 6vgJ and FIG. 7 are diagrams showing other embodiments of the present invention. The mounting bracket 33 in this embodiment is integrally provided with a fixing plate 36 which is horizontally rotatable via a thin hinge 35 formed on the inclined side of a trapezoidal support part 34. Therefore, if this mounting bracket 33 is fixed to the vehicle body side bracket 10 with the screw 32,
The entire cooling unit 37 can be mounted in a horizontally rotatable state, and the blower unit 2 and heater unit 4 can be connected without any gap. Note that the other configurations and effects are the same as those of the previous embodiment, so redundant explanation thereof will be omitted. FIG. 8 is a diagram showing still another embodiment of the present invention. In this embodiment, the vehicle body side bracket 38 and the mounting bracket 3
9 are fixed with bolts 41 via elastic mounts 40. That is, a mounting bracket 39 having the same overall shape as the conventional example is provided to the cooling unit 37,
This mounting bracket 39 and the vehicle body side bracket 38. Mounting holes 42 and 43 are provided in each of the holes. An internally penetrating elastic mount 40 made of elastic rubber is attached to the mounting hole 43 on the vehicle body side bracket 38 side so as to protrude by a distance B toward the mounting bracket 39 side. Then, insert the collar 44 into this elastic mount 40,
A bolt 41 is further inserted into this collar 44 to attach the mounting bracket 39 and the vehicle body side bracket 38. Therefore, due to the elastic deformation of the elastic mount 40, the mounting bracket 39 can rotate (swing) vertically and horizontally with respect to the vehicle body side bracket 38, so that the cooling unit 37 can be rotated vertically and horizontally.
The whole can be horizontally rotatably mounted between the blower unit 2 and the heater unit 4. Additionally, an elastic mount 4 is provided between the vehicle body side bracket 38 and the mounting bracket 39.
Since a gap corresponding to the protrusion amount B of 0 is provided, even if the mounting bracket 39 is horizontally rotated, it will not interfere with the vehicle body side bracket 38, and it will also not rotate vertically (
It is also possible to adjust the positional deviation in that direction. The other configurations and effects are the same as those of the previous embodiment, so redundant explanation thereof will be omitted. In addition, in the above explanation, the mounting bracket 25.33
．． Although we mainly showed an example in which 39 has a horizontally rotatable structure,
The vehicle body side brackets 10, 38 may have a horizontally rotatable structure (as long as the cooling unit 23, 37 can be mounted in a horizontally rotatable state. [Effect] Installation of the cooling unit according to the present invention) Since the structure is as explained above, even if there is a misalignment between the blower unit and the heater unit, the cooling unit can be installed between the blower unit and the heater unit without any gaps, and the air conditioner's air This has the effect of reliably preventing performance degradation due to leakage.Also, as demonstrated in the embodiment, using an integral mounting bracket with a hinge is advantageous in terms of manufacturing and cost, and furthermore, using an elastic mount is advantageous in terms of manufacturing and cost. This elastic mount has a vibration absorbing function and can suppress vibration and noise generation at the connection part between the vehicle body side bracket and the mounting bracket, and can also rotate up and down, so it is possible to adjust the position shift in the vertical direction. There is also the additional effect of being able to do this.
