Abstract

Provided is a heating device and a refrigerator. The heating device includes a cylinder body provided with a pick-and-place opening, a door body configured to open and close the pick-and-place opening, an electromagnetic generating module configured to generate an electromagnetic wave signal, and a radiating antenna. The radiating antenna is configured to be electrically connected with the electromagnetic generating module to generate electromagnetic waves of a corresponding frequency according to the electromagnetic wave signal. The heating device further includes a signal processing and measurement and control circuit for measurement and control processing of the electromagnetic wave signal. The signal processing and measurement and control circuit is configured to be electrically connected with the electromagnetic generating module and is disposed at a rear lower part in the cylinder body.

First claim

The invention claimed is:

1 . A heating device configured to heat an object to be processed with electromagnetic waves, comprising:
a cylinder body, provided with a pick-and-place opening and configured to place the object to be processed; a door body, disposed at the pick-and-place opening and configured to open and close the pick-and-place opening; and a radiating antenna, arranged in the cylinder body and configured to radiate the electromagnetic waves, wherein the heating device further comprises: a signal processing and measurement and control circuit, disposed at a rear lower part in the cylinder body, wherein the signal processing and measurement and control circuit is integrated on a circuit board; and wherein the heating device further comprises: a drawer for carrying the object to be processed disposed in the cylinder body; and a housing, disposed under a bottom wall of the drawer and configured to separate an inner space of the cylinder body into a heating chamber and an electrical appliance chamber under the heating chamber, wherein the object to be processed and the circuit board are respectively disposed in the heating chamber and the electrical appliance chamber; wherein a rear part of the bottom wall of the drawer and a rear part of the housing are both recessed upward to form an accommodating space which is located in the cylinder body and at the rear lower part of the cylinder body and is under the rear part of the bottom wall of the drawer and the rear part of the housing, and the circuit board is accommodated in the accommodating space, with a rear part of the inner space of the heating chamber being over the accommodating space and the circuit board.

2 . The heating device according to claim 1 , wherein
the cylinder body is made of a metal and is configured to be grounded; and the heating device further comprises: a metal bracket, configured to connect the circuit board and the cylinder body.

3 . The heating device according to claim 1 , wherein
the circuit board is horizontally disposed; and a clamping tongue extending upward and inward is respectively formed on two lateral side walls of the housing, and the circuit board is clamped above two clamping tongues.

4 . A refrigerator, comprising:
a cabinet, defining at least one storage compartment; at least one cabinet door, configured to open and close the at least one storage compartment; a refrigerating system, configured to provide cooling capacity to the at least one storage compartment; and a main control board, configured to control the refrigerating system to work, wherein the refrigerator further comprises: a heating device according to claim 1 , disposed in one of the at least one storage compartment.

5 . The heating device according to claim 1 , wherein the radiating antenna is disposed in the electrical appliance chamber under the heating chamber.

6 . The heating device according to claim 5 , wherein the housing is made of non-transparent insulating material, and the electromagnetic waves generated by the radiating antenna pass through the housing to heat the object to be processed.

7 . The heating device according to claim 5 , wherein the radiating antenna is fixed to the housing.

8 . The heating device according to claim 1 , wherein the housing comprises a clapboard for separating the heating chamber and the electrical appliance chamber, and a skirt part fixedly connected with an inner wall of the cylinder body.

9 . The heating device according to claim 8 , wherein the housing further comprises a plurality of reinforcing ribs that connect the clapboard and the skirt part.
