Embodiment Construction

[0021] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0022] The inventor found that in the digital parameter calculation of the existing electric refrigerator, it is often necessary to determine whether the operating state of the refrigerator is on or off, and the existing method can only discuss one matter at a time. , or when the unit of another manufacturer is changed, the original judgment method will be deviated, which will cause the algorithm ...

Abstract

The invention is suitable for the technical field of refrigerators, and provides an electric refrigerator and a method and device for detecting the running state of a compressor in the electric refrigerator. The method comprises the steps of detecting whether the data of on-off state parameters of the compressor in the electric refrigerator is empty or not; if not, determining the running state ofthe compressor in the running process of the electric refrigerator based on the on-off state parameters; and if yes, determining the running state of the compressor based on threshold value judgmentof the parameters of the electric refrigerator, wherein the parameters comprise at least one of the load and the current of a compressor sliding valve or a frequency converter in the electric refrigerator and the current of the compressor. The running state of the compressor in the electric refrigerator is confirmed according to whether the electric refrigerator has the on-off state parameters ornot, when the running state of the compressor in the electric refrigerator cannot be confirmed, the running state of the compressor is determined through threshold value judgment of the parameters ofthe electric refrigerator, and accurate judgment of the running state of an electric refrigerator unit is achieved.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, in particular to an electric refrigerator and a method and device for detecting the running state of a compressor in the electric refrigerator. Background technique [0002] In the calculation of digital parameters of electric refrigerators, it is often necessary to first determine whether the operating state of the refrigerator is on or off. Through the judgment of this state, other parameters can be calculated only in the on state, otherwise the calculated results will be have the opposite effect of being misleading. [0003] However, it is not easy to judge the operating state of the refrigerator, because in practice, some manufacturers have the parameter point of on-off state, and some do not have this state point. Even in the case of this parameter point, there are different definitions in different manufacturers. For example, the value "1" is used to represent the start-up, but the d...
