Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

Therefore, the refrigerator can be defrosted in time no matter the refrigerator is used under normal use or abnormal use conditions, and other problems caused by poor refrigeration or non-refrigeration of the refrigerator due to untimely defrosting are avoided. The defrosting exit condition is also divided into two blocks, one is that the defrosting sensor achieves temperature control and defrosting duration control, and the defrosting exits when the two conditions meet one of the two conditions. The defrosting heater is prevented from being heated for a long time to melt or burn refrigerator parts close to the heater to cause potential safety hazards.
The invention is further illustrated by the following examples.
Example 1
As shown in fig. 1, in the present embodiment, a defrosting control method for a refrigerator is disclosed, which is provided with several defrosting entry conditions to determine when to defrost based on the fact that the refrigerator is provided with a freezing sensor in a freezing chamber and a refrigerating sensor in a refrigerating chamber.
The method specifically comprises the following steps: a first preset condition S1, setting defrosting entry conditions according to the environmental temperature, the door opening times and the accumulated running time of the compressor; a second preset condition S2, setting defrosting entering conditions according to the refrigerating and freezing gear, the ambient temperature and the refrigerator running time; a third preset condition S3, setting defrosting entering conditions according to the refrigerating and freezing gear, the ambient temperature, the freezing sensor temperature, the refrigerating sensor temperature and the condition duration; and a fourth preset condition S4 for setting a defrosting entry condition according to the refrigerating sensor temperature and the defrosting sensor temperature and the condition duration. Since most refrigerators are currently provided with two operation modes, i.e., an energy saving mode and a non-energy saving mode, the first preset condition S1 among the preset conditions is only applicable to the non-energy saving mode operation of the refrigerator, the second preset condition S2 is only applicable to the energy saving mode operation of the refrigerator, and the third preset condition S3 and the fourth preset condition S4 are applicable to the two modes. The energy-saving mode of the refrigerator is that the refrigerator automatically regulates and controls the refrigerating temperature according to the quantity of food materials and the external temperature, generally, the refrigerator has the function of a frequency conversion refrigerator, and electricity can be saved in the mode. The non-energy-saving mode is determined according to the energy-saving mode, namely, the refrigeration temperature cannot be automatically regulated according to the quantity of food materials and the external temperature, and the mode consumes relatively electricity.
The refrigerator performs normal refrigeration and operates in an energy-saving mode, and when any defrosting entry condition from the first preset condition S2 to the fourth preset condition S4 is met, the refrigerator automatically starts defrosting operation; the refrigerator performs normal refrigeration and operates in a non-energy-saving mode, and when any one of the first preset condition S1, the third preset condition S3 and the fourth preset condition S4 is met, the refrigerator automatically starts defrosting operation.
In the present embodiment, the first preset condition S1 is further set as follows: dividing the environment temperature condition into a plurality of first preset environment temperature intervals, and dividing the door opening times into a plurality of preset door opening time intervals; dividing the cumulative operation time of the compressor into a plurality of preset cumulative operation time lengths of the compressor according to a plurality of first preset environment temperature intervals and a plurality of preset door opening time intervals; the refrigerator is in normal refrigeration operation, starting from the time when the accumulated operation time of the first preset compressor is reached, and meeting a first preset condition if the environment temperature is in a corresponding first preset environment temperature interval and the door opening times are in a corresponding preset door opening time interval. The length of the accumulated operating time of the compressor depends on the ambient temperature and the number of opening times, so that the accumulated operating time of the compressor is judged to be started at the shortest set accumulated operating time of the compressor, namely, the accumulated operating time of the compressor is judged from the first preset accumulated operating time of the compressor. The defrosting entry condition is suitable for a non-energy-saving mode in which the refrigerator runs in the working process, namely, the condition is judged in real time so as to monitor whether defrosting is needed or not.
At one set defrost entry condition, as shown in the following table:
when the defrosting calculation time is counted from the end of the last defrosting, and the compressor is operated accumulatively for 10 hours, the defrosting is started when the environmental temperature is judged to be more than or equal to 25 ℃ and the door opening times are more than or equal to 15 times; the defrosting calculation time is counted from the end of the last defrosting, and after the compressor is operated for 20 hours in an accumulated mode, when the environmental temperature is more than or equal to 25 ℃ and the door opening times are less than 15 times, defrosting is started; the defrosting calculation time is counted from the end of the last defrosting, and after the compressor is operated for 15 hours in an accumulated mode, if the ambient temperature is lower than 25 ℃ and the door opening times are more than or equal to 28 times, defrosting is started; and (4) counting the defrosting calculation time from the last defrosting end, and starting defrosting after the compressor is operated for 30 hours in an accumulated mode and when the environmental temperature is lower than 25 ℃ and the door opening times are lower than 28.

The application of this defrosting entry condition is limited to being in the energy saving mode.
The refrigerating and freezing gear comprises a refrigerating gear and a freezing gear, wherein the refrigerating gear is a weak gear at a temperature of more than or equal to 7 ℃, the freezing gear is a weak gear at a temperature of more than or equal to-17 ℃, the refrigerating gear and the freezing gear are weak gears when both the refrigerating gear and the freezing gear are weak gears, the refrigerating gear and the freezing gear are not equal to the weak gears when both the refrigerating gear and the freezing gear are not weak gears, and the refrigerator operation time is divided into a plurality of preset refrigerator operation time periods according to the weak gears and the second preset environment temperature interval respectively combined with the weak gears.
Specifically, one of the setting conditions is as follows:
