Embodiment Construction

[0023] The driving circuit and the driving circuit applicable to the operation control method of the linear compressor of the present invention figure 1 same.

[0024] image 3 It is a flowchart of the operation control method of the linear compressor of the present invention. Such as image 3 As shown, the operation control method of the linear compressor of the present invention has the following process: After the linear compressor is driven, it is confirmed whether a current trip occurs; if a current trip occurs and the linear compressor is shut down as a result of the confirmation, the linear compressor is repeatedly started.

[0025] Refer below figure 1 , the driving of the linear compressor in the present invention will be described in detail.

[0026] First, after the linear compressor 30 is driven, the microcomputer 50 detects whether a current trip occurs through the current detection unit 40 , and if no current trip occurs, the linear compressor 30 is normally ...

Abstract

The present invention relates to the control method of linear compressor. The control method includes two steps of confirmation and repeated starting, that is, after the linear compressor is started, it is confirmed whether to produce current trip, and in case of producing current trip to shut down the linear compressor, the linear compressor will be started repeatedly. By means of the said method of the present invention, when the linear compressor is stopped by current trip, the compressor may be re-started without need of turning off the power supply before turning on, and this can prevent the stored matter from deteriorating.

Description

technical field [0001] The invention relates to a method for controlling the operation of a linear compressor used in a refrigerator, in particular to a method for controlling the operation of a linear compressor which repeatedly starts up the linear compressor after the current trips to prevent deterioration of storage items in the refrigerator. Background technique [0002] Generally, if the linear compressor generates a current trip, the driving of the above-mentioned linear compressor will be completely stopped, and the user needs to directly turn off the overall power supply and then turn it on again to start the above-mentioned linear compressor. [0003] figure 1 is a schematic diagram of a general linear compressor drive circuit. Such as figure 1 As shown, the driving circuit of the linear compressor includes: a rectifying and smoothing unit 10 , a current converter 20 , a linear compressor 30 , a current detecting unit 40 , a microcomputer 50 and a door driving un...
