Compressor start control method and system and refrigerator

Abstract

The invention provides a refrigerator, a compressor start control method and a compressor start control system. The compressor start control method includes the steps that current environment temperature is acquired; whether the current environment temperature is smaller than or equal to a first temperature preset value or not is judged; when it is judged that the current environment temperature is smaller than or equal to the first temperature preset value, a first temperature detection device arranged in a refrigerating chamber controls the on-off state of a compressor; and when it is judged that the current environment temperature is not smaller than or equal to the first temperature preset value, a second temperature detection device arranged in the refrigerating chamber controls the on-off state of the compressor. By the adoption of the technical scheme, it can be effectively guaranteed that the compressor of the refrigerator can be smoothly started when the environment temperature of the refrigerator is too low, and normal work operation of the refrigerator is guaranteed; a compensation heating device is prevented from being arranged in a refrigerator inner container of the refrigerator, and the freshness retaining performance of stored objects is prevented from being affected when the stored objects are placed attached to the refrigerator inner container; the temperature of the refrigerating chamber of the refrigerator can be accurately controlled, and therefore user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of household appliances, in particular, to a compressor start-up control method, a compressor start-up control system, and a refrigerator. Background technique [0002] At present, the temperature sensor of the mechanically refrigerated electronic refrigerator is installed in the refrigerator to sense the temperature inside the refrigerator. When the ambient temperature is too low, the starting temperature required by the sensor is difficult to reach due to the small load of the cabinet. Therefore, It is necessary to turn on the compensation heating device on the back of the refrigerator to heat the cabinet, and then make the temperature sensor reach the predetermined start-up temperature to start the operation of the compressor; however, since the compensation heating device (compensation heating wire) of the refrigerator is directly attached to It is placed on the back of the box, and the temperatu...

[0002] At present, the temperature sensor of the mechanically refrigerated electronic refrigerator is installed in the refrigerator to sense the temperature inside the refrigerator. When the ambient temperature is too low, the starting temperature required by the sensor is difficult to reach due to the small load of the cabinet. Therefore, It is necessary to turn on the compensation heating device on the back of the refrigerator to heat the cabinet, and then make the temperature sensor reach the predetermined start-up temperature to start the operation of the compressor; however, since the compensation heating device (compensation heating wire) of the refrigerator is directly attached to It is placed on the back of the box, and the temperature sensor is arranged at the side tank of the refrigerator. The compensation heating device directly transfers heat to the tank through the box, so the heat will reach the temperature sensor after passing a certain distance in the box, resulting in The temperature sensor in the refrigerator cannot sense the temperature rise in time, which delays its start-up time. In severe cases, it cannot be started; moreover, during this process, if the stored items in the refrigerator are placed close to the tank, the heat provided by the compensation heating device will directly act on the refrigerator. For the stored items close to the tank, thus affecting the freshness preservation performance of the stored items
