Refrigerating and freezing device

Abstract

A refrigerating and freezing device () includes a cabinet, wherein at least one storage compartment () is defined therein, and a heating cavity is defined in one of the storage compartments (); and an electromagnetic heating device, configured to supply electromagnetic waves into the heating cavity so as to heat a to-be-processed object, wherein the electromagnetic heating device is provided with an electromagnetic generation module () configured to produce an electromagnetic wave signal and a power supply module () configured to supply a power source to the electromagnetic generation module (). A power supply box () is provided above a top of the cabinet (), and heat dissipation holes configured to achieve communication between the interior of the power supply box () and an external environment where the power supply box () is located are provided in a box body of the power supply box (). The power supply module () is disposed in the power supply box (), a heat dissipation fan () is further provided in the power supply box () and is configured to drive airflow to flow between the interior of the power supply box () and the external environment where the power supply box () is located through the heat dissipation holes, so as to dissipate heat from the power supply module (). The decrease of service life and efficiency caused by temperature rise during continuous working of the power supply module () and burn hazards caused by unintentional touch by users are completely eradicated, and meanwhile space is saved.
