KR970028404A - Compressor Protector and Method of Refrigerator - Google Patents

Abstract

Provided are an apparatus and method for protecting a compressor from overdrive due to the high internal temperature of the refrigerator not reaching the compressor turn-off point. The compressor protection device counts from the time when the compressor starts to drive and outputs a first time information signal to the microcomputer when the predetermined time (for example, two hours) is counted, and the microcomputer inputs the first time information signal. If the high temperature received from the high temperature sensor does not reach the turn-off point of the compressor, the compressor is forcibly stopped.

Therefore, even if the internal temperature does not reach the predetermined set temperature by frequently opening and closing the refrigerator door in the summer, the compressor can be stopped at regular intervals to prevent the compressor from overdriving and extend the life of the refrigerator. .

Claims (6)

A refrigerator having a refrigerator / freezer temperature sensor for measuring the current inside temperature of the internal storage and a compressor driver for controlling the operation according to whether the measured temperature output from the refrigerator / freezer temperature sensor has reached a set temperature. A clock time counter unit (12) which counts from the time when the compressor starts driving and outputs a first time information signal when a predetermined time (for example, two hours) is counted; And a control unit (13) for outputting a control signal for forcing the compressor driving unit to stop the compressor when the first time information signal is received from the clock time counter unit (12). Protection. The clock time counter part 12 outputs a second time information signal to the control part when a predetermined time (e.g., 16 minutes) elapses from the time when the compressor is forcibly stopped. And the control unit (13) switches the refrigerator to a normal operation mode in response to the second time information signal. The compressor of the refrigerator of claim 1, further comprising an error state display unit indicating that the refrigerator is in an error state outside the refrigerator when the compressor is forcibly stopped by the output of the first time information signal. Protection. The display apparatus of claim 2, further comprising an error state display unit for indicating that the refrigerator is in an error state outside the refrigerator when the compressor is forcibly stopped by the output of the first time information signal. The compressor protection device of the refrigerator, characterized in that released when there is an output of the second time information signal. CLAIMS What is claimed is: 1. A method of protecting a compressor of a refrigerator, comprising: counting a time from a time point at which a compressor of a refrigerator starts driving; Outputting a first time information signal to a controller when the counting time reaches a predetermined value; And stopping the driving of the compressor in response to the first time information signal. The method of claim 5, further comprising: counting a time from the compressor driving stop point after the compressor driving stop step and outputting a second time information signal when a predetermined time has elapsed; And switching the refrigerator to a normal operation mode in response to the second time information signal. ※ Note: The disclosure is based on the initial application.
