Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a temperature sensor mounting device for detecting the temperature of ventilated air of an outdoor heat exchanger (hereinafter referred to as outside temperature) in an air conditioner. One of the purposes is to detect more accurately.

Hereinafter, the present invention will be described with reference to the accompanying drawings showing one embodiment thereof.

First, the schematic structure of the air conditioner will be explained with reference to FIG.

In the figure, 1 is the main body of the air conditioner, and the board 2
It is composed of an outer box 3 and a front grill 4.
Reference numeral 5 denotes a partition plate attached to the substrate 2, which partitions the inside of the air conditioner main body 1 into an indoor side 1a and an outdoor side 1b. An evaporator 6, a fan motor 7, a fan 8, and a compressor 12 are disposed on the indoor side 1a, and a condenser 9, a fan motor 10, and a fan 11 are disposed on the outdoor side 1b. The compressor 12 is surrounded by a heat insulating material 12a and is insulated from the indoor side 1a. 13 is outdoor side 1b
This is a temperature sensor mounting device mounted inside the condenser 9.

Next, the structure of the temperature sensor mounting device 13 is
This will be explained using figures. In the same figure, the mounting device 13
As shown in FIG.
A guide tube 15 that supports the lead wire 21, a fixing groove 16 and a rib 17 that prevent the lead wire 21 from moving, and a drip-proof wall 18 that extends in a tilted manner so as to cover the surroundings thereof. Equipped with Here, the lead wire 21 is wrapped in a vinyl tube 22, and then a fixing groove 16 and a rib 17 are formed as shown in FIG.
It is meandering and intricately bent to prevent it from coming off easily. Further, the lead wire 21 is connected to a control circuit (not shown) within the air conditioner main body 1. Further, the temperature sensor mounting device 13 is attached to a pipe 19 that vertically penetrates the fins 20 of the condenser 9 by means of a plurality of claws 14 provided inside the air conditioner main body 1.
It is installed so as to hold the 24 is the drip-proof wall 1
Temperature sensor 2
It extends in the direction away from 3.

In the above configuration, outside air is ventilated through the fan motors 7 and 10 and the fans 8 and 11. The temperature sensor 23 is mounted on the outdoor side 1b with its tip slightly protruding from the guide tube 15, and detects the temperature of the air outside the condenser 9. Furthermore, the vinyl tube 22 protects the lead wire 21 and also covers the tip of the temperature sensor 23 to prevent rainwater from adhering to it and to protect it.

Here, conventionally, the temperature sensor 22 has been appropriately attached without being exposed. Therefore, with such a structure, when rainwater is blown into the condenser 7, the temperature sensor 2
2, the temperature sensor 22 detects the temperature of rainwater without detecting the outside temperature. This makes temperature control uncertain and may cause malfunctions.

However, if the temperature sensor mounting device according to this embodiment is used, even if the feather water enters the condenser 9, the flow is regulated to the outside by the drip-proof wall 18, and the water droplets are surely drained by the water cutter 24. In this way, since rainwater is prevented from adhering to the temperature sensor 23, the temperature sensor 23 can reliably detect the ventilation outside temperature. Further, since the temperature sensor mounting device 13 uses the fixing groove 16 and the rib 17 to attach the lead wire 21 in a meandering manner, it will not come off even if the lead wire 21 is pulled.

In this embodiment, the drip-proof wall 18 is formed to be inclined, but the same effect may be obtained by forming the drip-proof wall 18 into a half-case shape so as to cover the entire upper part of the lead wire 21 in the projection plane. The effects of this can be obtained.

As is clear from the above embodiments, the temperature sensor mounting device for an air conditioner according to the present invention has a temperature sensor installed on the inside of the main body of the outdoor heat exchanger disposed in the main body of the air conditioner. A temperature sensor that detects air temperature and a temperature sensor mounting device that supports and fixes the temperature sensor are provided, and the temperature sensor mounting device is further provided with a drip-proof wall that covers at least an upper part of the temperature sensor, and the drip-proof Since the wall prevents rainwater blown into the outdoor heat exchanger from adhering to the temperature sensor, the temperature of rainwater is not detected, and the ventilation outside temperature can always be accurately detected. Since it has a structure that only covers the upper part of the sensor, it has various advantages such as being simple in structure and inexpensive to manufacture.
