Problems solved by technology

The disadvantage is that under normal working conditions, since the main heating component, the magnetron, will generate residual heat after the microwave oven finishes heating, the temperature will continue to rise for a period of time after the heating is finished. In order to prevent the temperature from rising to the temperature of the thermostat Disconnecting the temperature will cause abnormal action of the thermostat or burn out the thermostat. The disconnecting temperature of the thermosta

Abstract

The embodiment of the invention provides a magnetron cooling control method for a microwave oven, and the microwave oven, and belongs to the field of microwave ovens. The interior of the microwave oven is provided with a magnetron for generating microwave, and a cooling fan for cooling the magnetron. The method comprises the steps: detecting set work time T of the microwave oven; controlling the magnetron and the cooling fan to start at the same time when the set work time T is greater than a threshold value Ts, wherein the operation time of the magnetron is T-t, and the operation time of the cooling fan is T, so as to enable the magnetron to stop earlier than the cooling fan by the time t (t is within the range shown in the description). According to the technical scheme of the invention, the method can reduce the manufacturing and installation cost of the microwave oven while improving the working reliability of the microwave oven and prolonging the service life of the microwave oven.

Description

technical field [0001] The invention relates to the field of microwave ovens, in particular to a magnetron cooling control method for a microwave oven and the microwave oven. Background technique [0002] Microwave ovens usually use a magnetron capable of generating microwaves of 2.4 GHz to 2.5 GHz to disturb the molecular arrangement of food to generate intermolecular frictional heat to heat food. [0003] Existing microwave oven generally comprises shell, furnace body and chassis, and furnace body is fixed on the chassis, and shell cover is arranged on the outside of furnace body and is fixed with chassis, and shell is used for sealing microwave oven, prevents microwave from leaking. The inside of the furnace body is equipped with a furnace cavity for heating or cooking food and an electric field chamber installed with electric field devices for generating microwaves. A magnetron is installed on the side of the electric field chamber facing the furnace cavity, and the micr...
