Problems solved by technology
[0011] However, the above-mentioned technical method has the following problems: According to the refrigeration capacity, during the forward or reverse driving of the compressor, the compressor still rotates according to the predetermined forward or reverse rotation regardless of the instantaneously increased load, which reduces the freshness of the food. It takes a long time for the temperature inside to drop to the set temperature

Embodiment Construction
[0017] Hereinafter, referring to the accompanying drawings of an embodiment of the present invention, the detailed description is as follows.
[0018] figure 2 It shows the action flow chart of the control method of the forward or reverse rotation compressor of the refrigerator of the present invention. As shown in the figure, the operation process of the refrigerator that maintains the temperature in the refrigerator through the forward or reverse rotation of the compressor is as follows: the first The first stage (steps SP1-SP3): sensing the closing of the refrigerator door, and checking (CHECK) the temperature when the refrigerator door is closed;
[0019] The second stage (step SP4~SP7): After checking the temperature in the above-mentioned refrigerator, after the set time, judge whether the temperature in the refrigerator is above the set temperature, if the temperature in the refrigerator is Above the set temperature, the compressor rotates in the positive direction; ...

The control method for forward / backward rotation compressor in refrigerator is to sense the overload in the refrigerator and to make the compressor rotate in forward direction to provide great amount of cold air. In order to realize the said function, the present invention makes the compressor rotate in forward or backward direction to maintain the set temperature inside the refrigerator. The operation process includes: the first stage of sensing the close of the refrigerator door and detecting the temperature inside the refrigerator while the door is closed; the second stage of detecting the temperature inside the refrigerator after some set time, judging whether the temperature inside the refrigerator is above the set temperature, and if so, rotating the compressor in forward direction; and the third stage of rotating the compressor in backward direction if the temperature inside the refrigerator is lower than the set temperature.
Description
technical field [0001] The present invention relates to a control method (CLOCKWISE / COUNTERCLOCKWISE COMPRESSOR DRIVING CONTROL APPARATUS ANDMETHOD FOR REFRIGERATOR) of a forward or reverse rotary compressor of a refrigerator. Further, it relates to a method of sensing excessive load in a refrigerator and corresponding to the excessive load, The control method of the forward or reverse rotation compressor of the refrigerator in which the compressor rotates in the forward direction and quickly supplies a large amount of cold air in response to changes in the load. technical background [0002] In general, there are two types of refrigerating cycle systems suitable for refrigerators: a high refrigerating capacity circulatory system that provides cold air to the freezer and a low refrigerating capacity circulatory system that provides cold air to the refrigerating chamber. [0003] The high-capacity refrigerating cycle system or the low-capacity refrigerating cycle system, beca...
