Embodiment Construction

[0029] Now, exemplary embodiments of the present invention will be described in detail, examples of which are shown in the accompanying drawings, and the embodiments will be described below in order to explain the present invention by referring to the drawings.

[0030] The present invention relates to a method for a refrigerator having a vacuum chamber, the compressor 51 of the refrigerator for refrigeration and the vacuum pump 52 for drawing vacuum to the vacuum chamber will generate noise during operation, especially the compressor 51, During a period of time after startup and shutdown, the noise is louder. Therefore, it is necessary to avoid simultaneous occurrence of the noise generated by the compressor 51 and the vacuum pump 52 as much as possible. By controlling the starting time of the compressor 51 and the vacuum pump 52, the compressor 51 and the vacuum pump 52 do not run at the same time, so as to avoid the superposition of the two noises.

Abstract

The invention discloses a method used for a refrigerator. The refrigerator comprises a compressor (51), a vacuum pump (52) and a control unit (50) which is connected with the compressor (51) and the vacuum pump (52). According to the method, the control unit (50) judges whether the compressor (51) is started on the basis of the running condition of the vacuum pump (52), and / or the control unit (50) judges whether the vacuum pump (52) is started on the basis of the running condition of the compressor (51).

Description

[technical field] [0001] The present invention relates to a method for operating a refrigerator, in particular to an operating method for a refrigerator. [Background technique] [0002] Food can be stored for a long time in a refrigerated or frozen low-temperature environment. In addition to being affected by temperature, food storage will also be greatly affected by factors such as the oxygen content of the air in the storage environment and the concentration of bacteria. Food can be stored longer, and people want to provide a low-oxygen, low-bacteria food storage environment, such as setting up a vacuum chamber in the refrigerator. [0003] The formation of the vacuum environment in the vacuum chamber requires the vacuum pump to pump the air in the vacuum chamber for a period of time. The working time of the vacuum pump is determined according to the size of the vacuum chamber, the power of the vacuum pump and the requirements of the vacuum degree. Generally, the operating...
