Problems solved by technology

[0002] The current environmental temperature control instrument system for electrical parts of household refrigerators is mainly an integrated test temperature system. The cabinet where the ambient temperature is controlled is in a state of change when the heating wire and the refrigeration compressor are working, which is not conducive to home use. The environmental temperature control of the electrical parts of the refrigerator requires a stable temperature state, which is likely to cause damage to the electrical parts and affect the service life of the electrical parts

Abstract

The invention discloses an electrical part split type temperature testing system for a household refrigerator, and relates to the technical field of refrigerator electrical part temperature testing. The system comprises an industrial personal computer, a control panel, a frequency converter, an air supply fan, an air draft fan, a variable temperature box and a constant temperature box. A split type structure is adopted, household refrigerator electrical parts are placed in the constant-temperature box, the system heats or refrigerates the variable-temperature box, then the state of temperature balance in the constant-temperature box is achieved through the draught fan and by means of circulating flow of air, it is guaranteed that the environment temperature of the household refrigerator electrical parts is controlled within a stable range, and the service life of the electrical part is prolonged.

Description

technical field [0001] The invention belongs to the technical field of temperature testing of electrical parts of refrigerators, in particular to a split-type temperature testing system for electrical parts of household refrigerators. Background technique [0002] The current environmental temperature control instrument system for electrical parts of household refrigerators is mainly an integrated test temperature system. The cabinet where the ambient temperature is controlled is in a state of change when the heating wire and the refrigeration compressor are working, which is not conducive to home use. The environmental temperature control of the electrical parts of the refrigerator requires a stable temperature state, which is likely to cause damage to the electrical parts and affect the service life of the electrical parts. Contents of the invention [0003] The object of the present invention is to provide a split-type test temperature system for electrical parts of hou...
