The invention discloses a temperature adjusting device for a refrigerator, which comprises a temperature setting unit, a voltage and current detecting unit, a temperature converting unit and a refrigerating control unit. The temperature setting unit is used for outputting voltage value or current value corresponding to the temperature set by users, the voltage and current detecting unit is used for detecting change values of the voltage or current output by the temperature setting unit, the temperature converting unit is used for storing a corresponding meter of voltage change values and temperature change values or a corresponding meter of current change values or temperature change values and converting the detected voltage change values or the current change values into temperature change data according to the corresponding meter, and the refrigerating control unit is used for controlling corresponding temperature change values according to the temperature change data. The temperature adjusting device for the refrigerator achieves adjusting temperature and high accuracy of the refrigerator fast by detecting changes of voltage for controlling temperature output by the temperature detection unit. Additionally, the temperature setting unit adopted by the temperature adjusting device integrates a temperature turning up function and a temperature turning down function, reduces complexity of the circuit and reduces stoppage.
Description
technical field [0001] The present invention relates to a temperature adjusting device, in particular to a temperature adjusting device used in a refrigerator. Background technique [0002] In the existing refrigerators, the temperature is adjusted by a mechanical temperature control method or an electronic temperature control method. The mechanical temperature control device of the mechanical temperature control method has a complex structure, complicated processing technology, and troublesome installation. At the same time, due to the transmission adjustment through multiple components, the failure rate of the temperature control device is high. The existing electronic temperature control methods such as temperature control devices figure 1 As shown, the MCU1 (microcontroller) controls the refrigeration of the refrigerator correspondingly by detecting the opening and closing of the first switch 2, thereby reducing the temperature of the refrigerator by 1°C; in addition, t...
