Description

[Detailed Description of the Invention] a. Field of Industrial Application The present invention relates to an air conditioner for an automobile, and more specifically, an air conditioner for an automobile in which a thermistor is fixed outside a pair of cases accommodating an evaporator. Regarding the device.

b. Prior Art FIGS. 4 and 5 show a main part of a conventional automobile air conditioner 1.

In this device 1, the evaporator 2 is surrounded by a pair of cases 3 and 4, and the thermistor 5 is fixed outside the cases 3 and 4.

That is, the dents 6a, 6a,
A plurality of sets of blocks 6 and 7 having 7a are formed, and the blocks 6 and 7 are fastened by a clamp member 8 which is fitted into the recesses 6a and 7a to fix the pair of cases 3 and 4 to each other.

The thermistor 5 is fixed to the case 3 by fixing a holding piece 9 into which a part of the thermistor 5 is fitted with a screw 10 to a boss 11 formed in the case 3.

c. Problems to be Solved by the Invention By the way, in the above-mentioned conventional automobile air conditioner 1, the case 3,
Since different items such as the clamp 8, the holding piece 9, and the screw 10 are required for fixing the four members to each other and the thermistor 5, the number of parts is increased, which can improve the assembling workability. was difficult.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an air conditioner for an automobile, which can improve assembly workability.

d. Means for Solving the Problems In the present invention, in order to achieve the above object, an evaporator is sandwiched between a pair of cases, and a thermistor is fixed on the outside of the pair of cases. ,
In each of the pair of cases, a plurality of sets of protrusions having retaining claws and bosses having holes into which the protrusions are fitted are formed at corresponding positions, and any one of the protrusions is formed. An extension portion is provided on the boss portion so as to project outward, and a space formed between the extension portion of the protrusion portion and the boss portion and the pair of cases when the protrusion portion is fitted to the boss portion. The thermistor is configured to be held with one touch.

e. Embodiment Hereinafter, one embodiment of an automobile air conditioner according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 show an embodiment of the present invention.

The air conditioner 20 of the present embodiment includes an evaporator 21 and a pair of cases 22,2.
The thermistor 24 is fixed inside the cases 22 and 23 while being housed inside.

That is, around the lower end of the opening side of the case 22, the protrusions 25, 26, 26, 26 having the retaining claws 25a, 26a, 26a, 26a at the tip end are extended downward (of these, Two protrusions
26 is hidden in case 3 and not shown. ).

Here, in particular, the protrusion 25 is formed so that the protrusion 25 is projected outward.
It has b, and thereby has a substantially L shape.

Also, around the upper end of the opening side of the case 23, corresponding to the protrusions 25, 26, 26, 26 provided on the case 22, those claws 25a, 26.
Boss portion having holes 27a, 28a, 28a, 28a for inserting a, 26a, 26a
27, 28, 28, 28 are provided.

Here, in particular, the boss portion 27 is formed so that the boss portion 27 protrudes outward.
have b.

1 to 3, 22a and 23a are the thermistor 2
A notch forming a hole through which 4 passes, 22b and 23b are ridges and grooves formed on the mating surfaces of cases 22 and 23, and 22c and 23c are cases 22 and 23.
An introduction port forming portion that forms an introduction port 29 for introducing air into the evaporator 21 inside when 23 is matched with each other, and 23d is an exhaust for discharging the air sent to the evaporator 21 together with a part of the case 22 not shown. A discharge port forming portion forming an outlet (not shown), 30
Is an expansion valve of the evaporator 21.

Next, the operation of the present embodiment will be described, and the configuration of the present embodiment will be clarified.

That is, the evaporator 21 and the thermistor 24 are positioned at predetermined positions and surrounded by the cases 22 and 23 so as to be sandwiched therebetween. On this occasion,
The claws 25a, 26a, 26a, 26a of the projecting portions 25, 26, 26, 26 of the case 22 are inserted and engaged with the holes 27a, 28a, 28a, 28a of the boss portions 27, 28, 28, 28 of the case 23 and come off. Will be stopped. As a result, the evaporator 21 is housed in the cases 22 and 23. Also, the thermistor 24
Since the central portion 24a is located inside the projecting portion 25 before the cases 22 and 23 are matched with each other, the cases 22 and 2 are
When the three are matched, the notches 22a and 23b of the cases 22 and 23 are held, and the central portion 24a of the cases 22 and 23 is pushed with one touch.
Space surrounded by 23, protrusion 25 and boss 27
It is held within 31 (see FIG. 1).

In this way, when connecting the cases 22 and 23 to each other,
The thermistor 24 is fixed with one touch without the need for other parts.

f. Effect of the Invention As described above, according to the automobile air conditioner of the present invention, the pair of cases for accommodating the evaporator are connected to each other by the protrusion having the retaining claw and the boss portion into which the protrusion is fitted. In addition, since the thermistor is positioned and held and fixed in the space between the protruding part, the boss, and the case during this connection, no other parts are required and the thermistor Since the fixing can be performed with one touch, the number of parts can be reduced and the assembling workability can be easily improved.
