As shown in Figure 1 be the kind of refrigeration cycle (cycle) of general refrigerator, in such kind of refrigeration cycle, generally comprise compressor (1), condenser (2), the 1st evaporimeter (F-EVA), the 2nd evaporimeter (R-EVA) and capillary (3); Compressor (1), it can suck the cold media gas of the low temperature of being discharged by evaporimeter, low pressure, handles making it become the gas of high temperature, high pressure then by compression; Condenser (2), it can make the heat by the cold media gas of the high temperature of compressor (1) discharge, high pressure be discharged in water or the air, makes it become the saturated liquid of high pressure; The 1st evaporimeter (F-EVA), the refrigerant saturated liquid of the high pressure of discharging from condenser (2) can become the refrigerant liquid of low temperature, low pressure after by capillary (3), and this evaporimeter (F-EVA) can suck such refrigerant and make its evaporation, supplies cold air then in refrigerating chamber by heat exchange; The 2nd evaporimeter (R-EVA), the refrigerant saturated liquid of the high pressure of discharging from condenser (2) can become the refrigerant liquid of low temperature, low pressure after by capillary (3), and this evaporimeter (R-EVA) can suck such refrigerant and make its evaporation, supplies cold air then in refrigerating chamber by heat exchange;
At first, when carrying out freezing (force cold power circulation), the refrigerant that is compressed into high temperature, high pressure in compressor (1) can flow in the condenser (2) and be condensed, and can become the refrigerant of low temperature, low pressure afterwards after flowing through capillary (3).
Next, the 1st evaporimeter (F-EVA) sucks and makes its evaporation with the refrigerant of above-mentioned low temperature, low pressure, thereby discharges the saturated gas that does not have liquid component to refrigerating chamber.
When refrigerating (weak refrigeration power circulation), the refrigerant that is compressed into high temperature, high pressure in compressor (1) can flow in the condenser (2) and be condensed, and can become the refrigerant of low temperature, low pressure afterwards after flowing through capillary (3).
Next, the 2nd evaporimeter (R-EVA) sucks and makes its evaporation with the refrigerant of above-mentioned low temperature, low pressure, supplies cold air by heat exchange to refrigerating chamber then.
Here, the compressor that is adopted in the kind of refrigeration cycle of above-mentioned refrigerator can only rotate in the direction of the clock, thereby always with high way of output work, therefore the temperature at refrigerator keeps stable state; Under the situation that does not need very strong refrigeration, compressor also still carries out clockwise rotation, thus the problem of bringing power consumption to increase.
In order to address this problem, adopted in the present refrigerator a kind of can be according to the needs of refrigeration power and clockwise or the compressor that is rotated counterclockwise, and reduce power consumption by this technology.That is to say,, thereby entered stable state by being assert if surpassed the time point of a setting running time of refrigerator, so refrigerator will the drive compression machine by rotation counterclockwise, thereby produce weak refrigeration power, reduce power consumption.
But the problem that said method exists is: at compressor according to the needs of refrigeration power and clockwise or in the process that is rotated counterclockwise, even the situation of moment load increase takes place, compressor also still rotates by certain clockwise/counter clockwise direction, thereby the freshness of food is reduced.It is elongated also can to make temperature in the refrigerator reduce to the required time of design temperature simultaneously.
Summary of the invention
In order to overcome the above-mentioned shortcoming that prior art exists, the invention provides a kind of refrigerator clockwise/be rotated counterclockwise the method for controlling of operation of compressor, so that at compressor by rotating clockwise/counterclockwise and keeping in the refrigerator of design temperature, if there is the overload situation to take place, refrigerator just can monitor this situation so, and at this overload situation, makes the rotation of compressor clockwise direction, supply a large amount of cold air rapidly, thereby tackle the variation of this load apace
The technical solution adopted for the present invention to solve the technical problems is:
A kind of refrigerator clockwise/be rotated counterclockwise the method for controlling of operation of compressor, it is characterized in that controlling: i.e. the 1st stage by following four-stage, in this stage, compressor keeps stable by the temperature of clockwise/rotation counterclockwise and refrigerator inside, whether power supply is disconnected monitoring in this case; The 2nd stage, whether power supply is disconnected in the process of monitoring, if monitoring power supply has disconnected, in this stage, will judge whether surpassed the stipulated time to the time that recloses after disconnecting from power supply so, if the time that described power supply disconnects has surpassed the stipulated time, and power supply has been connected again after this, and compressor is rotated in the direction of the clock, then through making it by rotation counterclockwise after the stipulated time again; The 3rd stage, according to above-mentioned judged result, if connected again at the appointed time after described power supply disconnects, before in this stage, will making compressor keep power supply to disconnect so clockwise or be rotated counterclockwise direction and rotate; The 4th stage, in this stage, if when compressor also by clockwise described or when counterclockwise rotating, the temperature inside the box has reached design temperature, compressor just quit work (OFF) so, if described the temperature inside the box does not reach the temperature that the user sets, so just make refrigerator turn back to for the 1st stage again.
Description of drawings
