By inserting the sandwiching piece 8 of the holder 6 between the fins 4 of the indoor heat exchanger 3, the holder 6 is held on the air conditioner main body 1 side via the heat exchanger 3, and the holder 6 The holding portion 7 holds and fixes the thermistor 9 in front of the heat exchanger 3, and the thermistor 9 senses the room temperature during operation of the air conditioner.

[Problems to be solved by the invention]

The conventional thermistor mounting device for an air conditioner is configured as described above, and the thermistor 9 is mounted near the surface of the indoor heat exchanger 3 while being held by the holder 6, and the radiant heat of the heat exchanger 3 is attached. Therefore, there is a problem that a temperature error occurs between the room temperature and the sensed temperature, and the room temperature cannot be accurately controlled.

The present invention has been made to solve the above problems, and an object thereof is to provide a thermistor mounting device for an air conditioner that is not affected by radiant heat in the air conditioner body or outside wind.

[Means for solving problems]

In the thermistor mounting device according to the present invention, a vent hole communicating with the outside of the air conditioner body is formed in a base made of synthetic resin which is the bottom of the air conditioner body, and the base surrounds the vent hole. A wall is formed, a thermistor holding portion is formed above the ventilation hole, and a plurality of projections are provided on the outer surface inside the wall, and air is provided between the projections and the inner surface of the wall. A heat insulating material made of a foam forming a layer is arranged, the wall and the heat insulating material, a thermistor holding portion,
A cover made of synthetic resin is tightly fixed to the wall while covering the upper surface of the vent hole surrounded by the wall.

[Action]

The thermistor mounting device according to the present invention is located above a ventilation hole integrally provided in the bottom of the air conditioner main body, and the thermistor is held by a holding portion inside the wall surrounding the ventilation hole, and the periphery of the thermistor is the wall. Since the thermistor is surrounded by the heat insulating material provided inside and the cover tightly fixed on the wall, the thermistor is not affected by the radiant heat or the outside air of the heat exchanger arranged in the main body, and therefore is accurately Can sense room temperature.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

FIG. 1 is a perspective view in which a part of an integrated air conditioner equipped with a thermistor mounting device according to an embodiment of the present invention and installed in a window or the like is cut away. In FIG. 1, 1 is an air conditioner body, 2 is a front panel mounted on the front surface of the body 1,
Reference numeral 11 is a base forming the bottom of the main body 1. The base 11 is made of a synthetic resin molded product, and as shown in FIG. 2, a ventilation hole 12 having vertical and horizontal crosspieces, and a ventilation hole 12
The wall 13 rising from the periphery of the wall 13, the thermistor holding portion 14 extending above the ventilation hole 12, and the screw boss 15 protruding outward from the opposite side surfaces of the wall 13 are provided by integral molding. 17 is a heat insulating material integrally formed of foam,
The heat insulating material 17 is fixed inside the wall 13. Reference numeral 18 denotes a plate-like cover made of a synthetic resin molded product, etc.
8 covers the part surrounded by the wall 13, and the wall 13 and the heat insulating material 17
It is fixed on the wall 13 by closely adhering to the upper surface of the above and tightening the screw 19 to the screw boss 15 from above. Reference numeral 9 denotes a thermistor, which is held by the holding portion 14 via a holding tool 15, is surrounded by a heat insulating material 17 and a cover 18, and is arranged above the ventilation hole 12.

Next, the operation of this embodiment will be described. Base 11
The thermistor 9 is attached to the holding portion 14 provided by integral molding on the wall 13 via the holder 16, and the cover 13 is fastened to the wall 13 having the heat insulating material 17 from above from above with the screw 19 on the wall 13. Is assembled. Further, the thermistor 9 can sense the room temperature because the portion surrounded by the heat insulating material 17 and the cover 18 is communicated with the room through the ventilation hole 12.

In the above embodiment, the entire outer surface of the heat insulating material 17 is covered by the wall 1.
Although it is shown that it is closely attached to the inner surface of 3, this device
As shown in FIG. 3, a plurality of protrusions 20 are provided on each side of the outer surface of the heat insulating material 17, the projections 20 are brought into contact with the inner surface of the wall 13, and the outer surface of the heat insulating material 17 other than these contact portions is provided. And the wall 13
A space 21 may be provided between the inner surface and the inner surface. In the structure described above, the space 21 makes it difficult to transfer the heat from the wall 13 to the heat insulating material 17, so that the thermistor 9
The heat generated by the indoor heat exchanger in the air conditioner body with respect to the ambient temperature can be cut off more reliably than those shown in FIGS. 1 and 2, and the thermistor 9 can detect a more accurate room temperature.

[Effect of device]

As described above, according to the present invention, the synthetic resin base of the air conditioner body is provided with the ventilation hole communicating with the outside of the air conditioner body, is integrally formed with the base, and stands upright from the base. A wall surrounding the vent hole is provided, and a heat insulating material made of foam that forms an air layer between the wall and the inner surface is arranged inside the wall and surrounded by the wall, the heat insulating material, and the wall. The upper surface of the vent hole is covered with a synthetic resin cover and fixed tightly, and the thermistor is held in that space. Therefore, the insulating material around the thermistor is a foam and a synthetic resin with high thermal insulation. Due to the heat insulation effect by the above, there is no influence of radiant heat of the heat exchanger in the main body of the air conditioner.

In addition, the ventilation hole is provided in a place where it does not affect the air flow due to the air conditioning function of the air conditioner body, and the thermistor holding part is placed above the ventilation hole, so the influence of the temperature of the air flow of the air conditioner The temperature in the room where the air conditioner is installed can be accurately detected without being affected.

Then, a plurality of protrusions are provided on the outer side surface, these protrusions are brought into contact with the inner side surface of the wall, and the heat insulating effect made of a foam body in which an air layer is formed between the outer side surface and the inner side surface of the wall is used to improve the heat insulating effect. Since it can be increased, it is not affected by the radiant heat of the heat exchanger in the air conditioner body.
