step seven: when N is more than 600s, the compressor is turned off, the temperature of the defrosting sensor is judged, if the temperature of the defrosting sensor is more than or equal to A ℃, the operation is performed according to a 'single-stop mode of the compressor', and if the temperature of the defrosting sensor is less than A ℃, the operation is continuously circulated to the step four.

Description of the drawings:
FIG. 1 is a flow chart of a method for controlling single stop of a compressor of a mechanical air-cooled refrigerator at a low ring temperature.
The specific embodiment is as follows:
the invention is further described below with reference to the accompanying drawings.
The invention discloses a single stop control method of a compressor of a mechanical air-cooled refrigerator at low ring temperature, which comprises the following steps:
step one: the refrigerator normally operates;
step two: judging whether the following conditions are satisfied: the temperature of the defrosting sensor is less than or equal to minus 30 ℃ and the compressor continuously runs for more than 1 h;
the freezing chamber of the mechanical air-cooled refrigerator is not provided with a freezing chamber sensor, the temperature of the freezing chamber cannot be judged, whether the mechanical air-cooled refrigerator needs to be refrigerated or not is judged by the temperature of a refrigerating sensor, and when the mechanical air-cooled refrigerator needs to be refrigerated, the refrigerating fan and the compressor synchronously operate and simultaneously refrigerate the refrigerating fan and the compressor.
The very low temperature of the defrosting sensor indirectly indicates that the temperature of the freezing chamber is low;
the compressor running time is too long, and the freezing temperature can be indirectly judged to be low.
Step three: if the temperature of the defrosting sensor is less than or equal to minus 30 ℃ and the continuous operation of the compressor lasts for more than 1h, the compressor is operated according to a 'single stop mode of the compressor', otherwise, the compressor is operated according to a normal mode;
step four: under the 'single stop mode of the compressor', detecting the ring temperature to be more than 13 ℃, operating the refrigerator in a normal mode, and if the ring temperature is less than or equal to 13 ℃, continuing the next step;
when the ring temperature is low, the refrigerating time is too long, the refrigerating temperature is very low, and when the refrigerating temperature is too low, various performance problems such as high power consumption, more frosting and the like can occur.
Step five: judging a refrigerating sensor and a stop point, if the refrigerating sensor is not more than the stop point, the refrigerator operates in a normal mode, and if the refrigerating sensor is more than the stop point, continuing the next step;
the refrigerating sensor is more than the stop point to indicate that the refrigerating is needed, and the refrigerating sensor is less than or equal to the stop point to indicate that the refrigerating is not needed and the refrigerating machine operates in a normal mode.
Step six: judging whether the shutdown time N of the compressor reaches 600S, if N is more than 600S, turning off the compressor, turning on the fan, if N is less than or equal to 600S, turning on the compressor, and when the compressor is turned on and the fan is turned on, N=N+1 after 1S, and continuously circulating to the fourth step;
step seven: when N is more than 600s, the compressor is turned off, the fan is turned on, the temperature of the defrosting sensor is judged, if the temperature of the defrosting sensor is more than or equal to-18 ℃, the operation is performed according to a 'single-stop mode of the compressor', and if the temperature of the defrosting sensor is less than-18 ℃, the operation is continuously circulated to the fourth step.
The defrosting sensor temperature indirectly judges the temperature of the freezing chamber, when the defrosting sensor temperature is high, the compressor is started to refrigerate the freezing chamber and recalculate the starting time of the compressor.
The invention discloses a single stop control method of a compressor of a mechanical air-cooled refrigerator at low ring temperature, which utilizes the temperature of a defrosting sensor to indirectly judge the temperature of a freezing chamber, and independently switches off the compressor and independently switches on a fan to achieve the purposes of independently refrigerating and controlling the temperature of freezing.
The foregoing is merely a preferred embodiment of the invention, and it should be noted that modifications could be made by those skilled in the art without departing from the principles of the invention, which modifications would also be considered to be within the scope of the invention.
