Problems solved by technology

Therefore, if the defrosting operation is carried out when the amount of frost on the evaporator is small, there will be situations where there is no need to defrost and defrost, resulting in a waste of electric energy

Embodiment 1

[0053] A plurality of preset ranges are preset, that is, a first preset range less than 15 Pa, a second preset range greater than or equal to 15 Pa and less than 30 Pa, the first preset range corresponds to 72 hours, and the second preset range corresponds to 48 hours. If the current pressure difference between the first end and the second end is 17Pa, it can be seen that the current pressure difference is within the second preset range, and then it is obtained that the continuous power-on time of the refrigerator is 60 hours, that is, the continuous power-on time of the refrigerator is longer than the second preset The 48 hours corresponding to the range will enter the defrosting operation.

Embodiment 2

[0055] A plurality of preset ranges are preset, namely, a first preset range less than 10 Pa, a second preset range greater than or equal to 10 Pa and less than 20 Pa, a third preset range greater than or equal to 20 Pa and less than 30 Pa, the first preset The range corresponds to 72 hours, the second preset range corresponds to 48 hours, and the third preset range corresponds to 36 hours. If the current pressure difference between the first end and the second end is 17 Pa, it can be seen that the current pressure difference is within the second preset range, and then it is obtained that the continuous power-on time of the refrigerator is 35 hours, that is, the continuous power-on time of the refrigerator is less than the second preset If the range corresponds to 48 hours, no action is taken to avoid defrosting without frost.

Embodiment 3

[0058] Preset multiple preset pressure differences, and each preset pressure difference corresponds to a preset power-on time. After monitoring the current pressure difference between the first end and the second end, calculate the difference between the current pressure difference and each preset pressure difference Value to select the target pressure difference from a plurality of preset pressure differences, where the difference between the target pressure difference and the current pressure difference is the smallest; and then obtain the preset power-on duration corresponding to the target pressure difference to keep the refrigerator current continuous The power-on duration is compared with the corresponding preset power-on duration to determine whether to enter the defrosting operation. For example, multiple preset pressure differences include: 10 Pa, 20 Pa, 30 Pa, 10 Pa corresponds to 72 hours, 20 Pa corresponds to 48 hours, and 30 Pa corresponds to 36 hours. If the curre...

Abstract

The invention provides a defrosting control method, a defrosting control device and a refrigerator. The defrosting control method includes the steps that the current pressure difference between a first end and a second end of an evaporator of the refrigerator is monitored, and cold air flows from the first end to the second end; whether defrosting operation is started or not is determined according to the current pressure difference. Through the technical scheme, accurate control over defrosting can be realized, the situation that defrosting operation is started when not necessary is avoided, and therefore the electricity of the refrigerator is saved.

Description

Technical field [0001] The invention relates to the technical field of household appliances, in particular to a defrosting control method, a defrosting control device and a refrigerator. Background technique [0002] In related technologies, such as figure 1 As shown, the defrosting control method of the refrigerator includes: step 102, when the refrigerator is powered on, start timing; step 104, determine whether the refrigerator continues to be powered on for ≥ 48 hours, if the judgment result is yes, go to step 114, otherwise go to step 104; Step 106, count the compressor cumulative time t1; Step 108, count the compressor continuous running time t2; Step 110, determine whether t1≥10 hours, if the determination result is yes, go to step 114, otherwise, go to step 106 Step 112, it is judged whether t2≥10 hours is satisfied, if the judgment result is yes, go to step 114, otherwise, go to step 108; Step 114, go to the defrosting operation. It can be seen that, in order to ensure ...
