Abstract: Disclosed is a refrigerating and freezing device, including: a storage compartment partitioned into a plurality of first spaces; a cooling chamber configured to accommodate an evaporator of the refrigerating and freezing device; an air channel system having a plurality of first air supply outlets, a main return air outlet and an on-off control device; and a plurality of drawers, wherein each drawer is mounted in one of the first spaces, each drawer has an air inlet and a return air outlet, each air inlet is communicated with one of the first air supply outlets, and each return air outlet is communicated with the main return air outlet; and the on-off control device is configured to control air flow from the cooling chamber to flow to one or more of the plurality of first air supply outlets, and then control all or part of the air flow to flow to the corresponding drawers.

Abstract: Disclosed is a heating device (100), including: a metal cylinder body (110) provided with a pick-and-place opening, a door body (120) configured to open and close the pick-and-place opening, an electromagnetic generating module (161) configured to generate an electromagnetic wave signal, and a radiating antenna (150). The radiating antenna (150) is configured to be electrically connected with the electromagnetic generating module (161) to generate electromagnetic waves of a corresponding frequency according to the electromagnetic wave signal. The heating device (100) further includes an antenna housing (130) made of an insulating material.

Abstract: Disclosed is a refrigerating and freezing device (200), including a cabinet defining at least one storage compartment, a refrigerating system configured to provide cooling capacity to the at least one storage compartment, and a heating unit (100). The heating unit (100) includes a metal cylinder body (110) disposed in one storage compartment, a door body (120) configured to open and close a pick-and-place opening of the metal cylinder body (110), and an electromagnetic generating system generating electromagnetic waves in the cylinder body (110) to heat an object to be processed. At least a part of the electromagnetic generating system is disposed in the cylinder body (110) or accessed into the cylinder body (110).

Abstract: A drawer assembly includes: drawers, arranged in a storage compartment of the refrigerator in a way of being capable of being pushed and pulled forward and rearward between a front extreme position and a rear extreme position; and two support assemblies in left-right parallel arrangement. Each of the support assemblies includes a support frame. The support frame is fixed to an inner wall of the storage compartment, is provided on an inner side with a first slideway extending forward and rearward, and is provided on a rear portion of the inner side with an elastic tongue. A left sidewall and a right sidewall of the drawer are respectively mounted on the first sideway of the support frame of one of the support assemblies in a forward and rearward slidable way.
