Problems solved by technology

Therefore, this method needs to set a reasonable defrosting thickness according to the actual situation. If the defrosting thickness is set too large, the defrosting time will be delayed and the defrosting effect will be unsatisfactory; if the defrosting thickness is set too small, It will also make the time to start defrosting earlier and increase energy consumption
Therefore, the problem of defrosting thickness setting makes this method difficult to use on products, and the practicability is poor

Abstract

The embodiment of the invention provides a defrosting sensor, a refrigerator and a defrosting method. The defrosting sensor can regulate defrosting thickness in a self-adaptive mode to achieve accurate and reliable defrosting and comprises a first supporting seat, a second supporting seat, a first temperature sensor arranged on the outer surface of the first supporting seat / the second supporting seat, a light transmitting end, a light receiving end and a second temperature sensor arranged on one of two opposite faces of the first supporting seat and the second supporting seat, wherein the first supporting seat and the second supporting seat are arranged oppositely, the light transmitting end and the light receiving end are arranged on the two opposite faces of the first supporting seat and the second supporting seat respectively, the light transmitting end and the light receiving end are arranged oppositely. The defrosting sensor, the refrigerator and the defrosting method are suitable for the technical field of electrical appliance devices.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a defrosting sensor, a refrigerator and a defrosting method. Background technique [0002] With the improvement of people's living standards, refrigerators have been widely used. [0003] Long-term operation of the refrigerator will cause a certain thickness of frost on the surface of the evaporating tube inside the refrigerator. If the frost layer is too thick, the heat exchange efficiency of the evaporating tube will be reduced, resulting in a decrease in the cooling efficiency of the refrigerator. Therefore, after the refrigerator has been in operation for a period of time, it needs to drive the defrosting heating tube installed near the evaporating tube to heat, so as to melt the frost attached to the surface of the evaporating tube. At present, there are many control methods to realize defrosting. Among them, it is more commonly used to use a frost layer thick...
