Title:
DEFROSTING CONTROL METHOD, SENSOR ASSEMBLY, EVAPORATOR AND DEFROSTING CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/221678
Kind Code:
A1
Abstract:
Provided are a defrosting control method, a sensor assembly (2), an evaporator (1), a defrosting control apparatus, an electronic device, a non-transitory computer-readable storage medium, and a computer program product. The defrosting control method comprises: acquiring a first detection signal of a first piezoelectric component (21), wherein the first piezoelectric component (21) is connected to an evaporator (1), and the first detection signal corresponds to the thickness of a frost layer on the surface of the first piezoelectric component (21); acquiring a second detection signal of a second piezoelectric component, wherein the second piezoelectric component is connected to the evaporator (1) and is located in a frost-free space, and the second detection signal is a reference signal corresponding to the environment of the first piezoelectric component (21); obtaining a calculation difference value between the first detection signal and the second detection signal; and when determining that the calculation difference value reaches a preset threshold value, performing defrosting.
