A temperature controller with temperature compensation and temperature compensation method

Abstract

The invention discloses a temperature controller with temperature compensation, which comprises a casing, a heating compensating component, a mechanical component arranged inside the casing, and a temperature-sensing component arranged at the bottom of the casing, the temperature-sensing component includes corrugated tube, and a capillary tube connected to the bellows, the heating compensation assembly includes a temperature sensor switch and a heater, the heater is arranged inside the housing and connected to the terminal inside the electrical interface assembly, the The electrical interface assembly is located on the side wall of the housing, the temperature sensor switch is a magnetic switch or a temperature switch, and the heater is a resistance wire or a resistance heating sheet. The invention enhances the low temperature tolerance of the temperature control by adding a heating compensation component inside the temperature controller, and at the same time solves the defect that the existing temperature controller cannot be started normally in a low temperature environment; the heating compensation component is reasonably connected with the electrical interface component , Realize the automatic compensation function of the thermostat temperature.

Description

technical field [0001] The invention relates to the field of temperature controllers, in particular to a temperature controller suitable for low-temperature environments with a temperature compensation function, and a method for realizing the temperature compensation function by using the temperature controller. Background technique [0002] The thermostat is an automatic control element that physically deforms inside the switch according to the temperature change of the working environment, thereby producing a series of actions such as conduction or disconnection. The refrigerator thermostat is an important component of refrigerator temperature regulation, and its normal operation has an important impact on the normal startup of the refrigerator. Due to the particularity of its structure, the thermostat often fails to start due to the influence of freezing in a low temperature environment, causing inconvenience to users. For example: when the winter is too low (eg -10°C) i...

Problems solved by technology

[0004] In order to overcome the defects of the existing thermostats such as limited low-temperature resistance and easy failure to start, the technical problem to be solved by the present invention is to propose a thermostat with temperature compensation, which has the temperature compensation function of the thermostat and stable startup. Strong low temperature resistance, effectively solves the defect that the thermostat is difficult to start at low temperature
