Micro-wave oven

Abstract

The invention provides a microwave oven. The microwave oven comprises a shell, a microwave generation device, a heating tube, a heating tube cover, an air duct, a fan and a door, wherein the heating tube cover is arranged on the top of the shell and is communicated with a cavity enclosed by the shell through an opening or a plurality of through holes formed on the bottom of the heating tube cover. The microwave generation device and the fan are arranged at one side of the shell. The heating tube comprises two heating tubes which are supported on the top of the shell through the heating tube cover. The heating tube is arranged at the side of the shell. The air duct warps the heating tube cover and the heating tubes form the outside. An opening at one end of the air duct is arranged at a positioning corresponding to the fan and the other end of the air duct is communicated with the other side of the shell. Part of wind blown out from the fan is blown into the heating tube through the air duct to bring the heat generated on the surface the heating tube cover and by the heating tube to a chamber of the oven through the top and sides of the shell to accelerate the air flow in the chamber of the oven and make the heat distributed evenly. And the top heating tube and the side heating tube can work independently and can be set in different states according to different food cooling equipments.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a microwave oven with a barbecue function, which belongs to the modification technology of the microwave oven. Background technique [0002] Existing microwave ovens with barbecue function use heat pipes to heat food from top to bottom mainly through heat radiation. The disadvantages are that the temperature rise in the oven cavity is slow, the temperature difference between the upper and lower sides of the oven cavity is large, and the barbecue effect is low. It is not very ideal, and the hot air convection mechanism of the traditional microwave oven is relatively complicated, and the cost is also quite high. Simultaneously, except that the cooling fan of microwave oven is directly used to reduce the temperature of microwave oven components, it does not make a major direct contribution to increasing the temperature in the oven cavity.

[0002] Existing microwave ovens with barbecue function use heat pipes to heat food from top to bottom mainly through heat radiation. The disadvantages are that the temperature rise in the oven cavity is slow, the temperature difference between the upper and lower sides of the oven cavity is large, and the barbecue effect is low. It is not ideal, and the hot air convection mechanism of traditional microwave ovens is relatively complicated and the cost is quite high

At the same time, the cooling fan of the microwave oven does not make a major direct contribution to increasing the temperature in the oven cavity, except that it is directly used to reduce the temperature of the components of the microwave oven.
