Title:
CONTROL METHOD FOR REFRIGERATION AND FREEZING DEVICE AND REFRIGERATION AND FREEZING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/002089
Kind Code:
A1
Abstract:
A control method for a refrigeration and freezing device (100), and a refrigeration and freezing device (100). The refrigeration and freezing device (100) comprises a cabinet body (110) defining at least one storage compartment, an electromagnetic wave generation system for generating electromagnetic waves in a storage compartment or part of a storage compartment to heat an object to be treated, and a first fan (141) and a second fan (142) which are used for dissipating heat of a device of the electromagnetic wave generation system by means of the ambient air of the refrigeration and freezing device (100). The control method comprises: acquiring the ambient temperature of the refrigeration and freezing device (100) and the surface temperature of the device; according to the ambient temperature, determining the basic rotational speed of the first fan (141) and the basic rotational speed of the second fan (142); and according to the surface temperature, adjusting the rotational speed of the first fan (141) and the rotational speed of the second fan (142) on the basis of the basic rotational speed. Efficient heat dissipation is achieved such that the continuous running time of the electromagnetic wave generation system can be prolonged, thereby ensuring the effects of unfreezing and defrosting and the service life of a heating device, and meanwhile reducing power consumption of the refrigeration and freezing device (100).
