[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to mounting a temperature sensor for an air conditioner.

[0002]

[Prior art]

 In recent years, air conditioners have been required to have finer precision for temperature control because of improved comfort.

As for mounting a temperature sensor of a conventional air conditioner that detects a suction temperature, there is one disclosed in Japanese Utility Model Publication No. 2-3072.

An example of the conventional air conditioner described above will be described below with reference to the drawings. FIG. 3 is a schematic configuration diagram showing a conventional air conditioner, in which an indoor unit main body 1 is provided with an indoor heat exchanger 2 and a blower 3 (not shown).

FIG. 4 is an enlarged view of a main part of FIG. 3, wherein the indoor heat exchanger 2 includes a plurality of heat radiating fins 4 in a vertical direction and a plurality of cooling pipes 5 in a horizontal direction inside the heat radiating fins 4. It is composed of. A temperature sensor fixture 7 for fixing the temperature sensor 6 is provided on the suction side of the indoor heat exchanger 2 and is fixed so as to be in contact with the suction side end surface of the heat radiation fin 4.

The temperature sensor 6 is held by a first vertical plate 7 a extending on the suction side of the temperature sensor fixture 7, and the temperature sensor fixture 7 is a cutout of a second vertical plate 7 b extending on the indoor heat exchanger 2 side. 8 is inserted and fixed in the cooling pipe 5.

The operation of the air conditioner configured as described above will be described below.

During operation of the air conditioner 1, the indoor air is sucked from the suction side of the indoor heat exchanger 2 according to the flow of air, and the indoor temperature is detected by the temperature sensor 6 mounted on the front surface of the indoor heat exchanger 2. , Controls ON-OFF of the compressor according to the set conditions.

[0009]

[Problems to be solved by the device]

 However, in the above configuration, the temperature sensor fixture 7 contacts the heat radiation fins 4 of the indoor heat exchanger 2 and the cooling pipe 5 is located in the vicinity thereof, so that the temperature sensor fixture is fixed by the heat conduction of the cooling pipe 5. The tool 7 itself is cooled and the temperature sensor 6 is affected by cold radiation and heat conduction of the temperature sensor fixing tool 7, and a temperature difference occurs between the room temperature and the temperature detected by the temperature sensor 6. Lose control accurately.

In view of the above problems, the present invention provides an air conditioner in which a temperature sensor can detect a more accurate temperature with respect to a set temperature.

[0011]

[Means for Solving the Problems]

 In order to solve the above problems, the air conditioner of the present invention has a configuration in which the cooling pipe of the heat exchanger in the portion close to the temperature sensor fixture is eliminated.

[0012]

[Action]

 The present invention has the above-described configuration, and the temperature sensor fixture of the temperature sensor is not affected by the heat of the cooling pipe of the heat exchanger adjacent thereto.

【Example】

 An air conditioner according to an embodiment of the present invention will be described below with reference to the drawings. The same components as those of the conventional device will be designated by the same reference numerals and detailed description thereof will be omitted.

FIG. 1 is a schematic internal structural view of an air conditioner according to an embodiment of the present invention. Reference numeral 9 is an indoor unit body of an air conditioner, and a suction port 10 and a blowout port 11 are formed on the front surface. . Reference numeral 12 denotes an air passage formed inside the indoor unit main body 9, which communicates with the suction port 10 and the blow-out port 11, and inside of which an indoor heat exchanger 13 and a blower 14 which constitute a well-known refrigeration cycle are provided. Are arranged. Reference numeral 15 denotes a water tray of the indoor heat exchanger 13, which also serves as a stabilizer of the blower 14. Reference numeral 16 is a temperature sensor for detecting the temperature of the indoor air sucked through the suction port 10, and is fixed to the suction side of the indoor heat exchanger 13 by a temperature sensor fixture 17.

These are the same as those in the existing air conditioner, and the air filter, the front grill, the fan motor, and the like are not shown, but they are provided as is well known.

FIG. 2 is an enlarged view of a main part of FIG. 1. Reference numeral 13 denotes an indoor heat exchanger, which includes a plurality of heat radiating fins 18 in a vertical direction and a plurality of cooling pipes 19 in a horizontal direction inside the heat radiating fins 18. There is.

A temperature sensor fixing tool 17 for holding the temperature sensor 16 is arranged on the suction side of the indoor heat exchanger 13, and the temperature sensor fixing tool 16 is arranged so as to be in contact with the heat radiation fins 18. The temperature sensor 16 is fixed by a first vertical plate 17a extending vertically to the suction side, and the temperature sensor fixture 17 is a second vertical plate extending toward the indoor heat exchanger 13 side in the vertical direction of the temperature sensor fixture 17. The notch 17c of 17b is fitted and fixed to the cooling pipe 19 of the indoor heat exchanger 13.

The first vertical plate 17a is appropriately deviated from the second vertical plate 17b in the upward direction, and is adjacent to the indoor heat exchanger 13 where the temperature sensor 16 held by the first vertical plate 17a is located. The cooling pipe 19a is excluded.

The operation of the air conditioner of the present embodiment configured as above will be described below.

When the operation is performed with the above configuration, the air in the room is sucked in from the suction side of the indoor heat exchanger 13, hits the temperature sensor 16, passes through the indoor heat exchanger 13, and is blown out from the outlet 11.

Since the cooling pipe 19 a of the indoor heat exchanger 13 adjacent to the temperature sensor 16 is excluded, the heat of the cooling pipe 19 does not directly affect the temperature sensor fixture 17 and the temperature sensor fixture 17 Is the same as the indoor air temperature, and the thermal effect on the temperature sensor 16 is also eliminated.

As described above, the temperature detection of the temperature sensor 16 can be extremely less affected by the heat of the cooling pipe 19a of the indoor heat exchanger 13, and a more accurate indoor air temperature can be detected.

[0023]

[Effect of device]

 As described above, according to the present invention, the indoor heat exchanger including the plurality of heat radiation fins and the plurality of cooling pipes, the blower, and the like are provided, and the temperature sensor is fixed to the suction surface of the indoor heat exchanger. By providing a temperature sensor fixture and eliminating the cooling pipe of the indoor heat exchanger that is in close proximity to the temperature sensor of the temperature sensor fixture, the heat effect on the temperature sensor is reduced and more accurate intake air temperature can be detected. it can.
