Abstract

The invention discloses a pressure-type temperature controller which can ensure that no electric current flows from a refrigeration compressor of a refrigerator when the refrigeration compressor is stopped, thus being applicable to the refrigeration compressors of all kinds of refrigerators. In the pressure-type temperature controller, M terminal is added in a switch box based on the current single-pole single-throw pressure-type temperature controller with an auxiliary switch and among the C terminal, L terminal and M terminal are provided with a single-pole double-throw switch which can operate automatically according to the temperature change.

Description

technical field

[0001] The invention relates to the technical field of mechanical temperature controllers, in particular to a pressure type temperature controller used in a refrigerator to control the startup and shutdown of a refrigeration compressor and other auxiliary circuits. Background technique

[0002] The pressure thermostat is widely used in the refrigeration control of refrigerators. The existing pressure thermostat with auxiliary switch is composed of bellows, pressure plate, temperature adjustment spring, adjustment shaft assembly and switch box assembly in the main body. see figure 1 , figure 2 shown. The switch box assembly consists of switch box 1, C terminal 2, L terminal 3, H terminal 4, moving contact 5, auxiliary contact 6, bow spring 7, moving contact 8, H static contact 9, L static contact 10. An auxiliary contact 11 and an auxiliary push rod 12 are formed. C terminal 2, moving contact 8, moving contact piece 5, bow spring 7, L terminal 3, and L st...
