器が知られている。Conventionally, temperature regulators for air conditioners are either bimetallic temperature regulators that open and close contacts by the displacement of a bimetal due to changes in ambient temperature, or bimetallic temperature regulators that open and close contacts by the displacement of a diaphragm that is filled with gas and expands and contracts. A diaphragm type temperature control device is known.

When the contact point a turns OFF and the air conditioner stops operating, the indoor heat exchanger of the air conditioner is cold, so the radiant cold heat cools the heat sensitive tube f of thermostat a) and the indoor temperature decreases. There was a problem in that even if the temperature rose, the contact point of thermostat (a) remained open and the air conditioner would not resume operation in accordance with the air temperature changes.

の構造は従来周知であるため説明は省略する。In the figure, reference numeral 1 denotes a diaphragm type temperature regulator which is fixed to a power supply board 3 with screws 2 via metal fittings. This temperature regulator 1 has a diaphragm 4 sealed with gas, and the diaphragm 4 and the temperature sensing section 5 are connected by a capillary tube 6. The structure of this diaphragm type temperature regulator 1 itself is well known in the art, so a description thereof will be omitted.

込まれ、ネジ１３により数個けられている。One end of the diaphragm 4 is exposed to the outside of the temperature controller 1, and the exposed diaphragm 4 is
In order to ensure that the center part is in close contact with the exposed end of the diaphragm 4, it is fixed to the power supply board 3 using two screws with the metal fittings 8 straddling it. In this installation, several heating resistors 1o whose outer peripheries are covered with ceramic cement 9 are sandwiched between fixing fittings 12 that form a pair with the fitting 8, with a protective silicone rubber sheet 11 interposed between them. Several screws 13 are provided.

Although only a small divided voltage was applied to the heating resistor 10, a large voltage is applied to the heating resistor 10 by turning off the contact of the temperature regulator 1. Therefore, the heating resistor 10 generates heat, and this resistor 1
The cement 9 on the outer periphery of the holder 0 is heated, and this heats the mounting fitting 8 and the fixing fitting 12. Since the fitting 8 and the diaphragm 4 of the temperature regulator 1 are in close contact with each other during this installation, the diaphragm 4 is heated, the gas within the diaphragm 4 expands, and the contact is turned ON by the pressure.

えるなどの効果を奏する。As is clear from the above embodiments, the present invention seals the diaphragm of a temperature controller that opens and closes the electrical contacts of a compressor or blower, and utilizes the displacement of the diaphragm when the ambient temperature changes. Since the heat generating resistor is attached to the diaphragm through the metal fittings, the heat of the heat generating resistor can be transferred to the diaphragm very efficiently. If the contact of the controller turns OFF, the contact of the thermos fan 71 will turn ON immediately after a certain period of time has elapsed, ensuring reliable cooling operation.Moreover, the installation requires less space, and can be used at low cost according to the indoor load. This has the effect of improving air conditioning.
