Microwave oven

Abstract

The invention provides a microwave oven which comprises a microwave oven shell defined by a bottom plate, an outer case, a front plate and a back plate, wherein an electrical room and a hollow cooking cavity are arranged in the shell; the hollow cooking cavity is defined by a top plate, the front plate, a U-shaped plate and the back plate, and is open at one end; the shell is provided with an air inlet and an air outlet; a fan is arranged in a manner of being dead against the air inlet; a heating pipe hood covering heating elements is arranged on the top plate; a first air channel is formed among a back wall of the heating pipe hood, the back plate and the outer case; a second air channel is formed among a front wall of the heating pipe hood, the front plate and the outer case; an air inlet hole is formed in a side plate of the U-shaped plate, and an air outlet hole is formed in the other side plate of the U-shaped plate; the air inlet hole, the air outlet hole and the cavity form a third air channel; in the electrical room, an air guide plate is arranged at the air outlet of the fan; the air guide plate can guide cold air blown out by the fan to pass through the first, second and third air channels respectively, and flow out via the air outlet. The microwave oven provided by the invention has the advantages that the temperature of the surface of the microwave oven can be effectively reduced, and the safety of the microwave oven is improved.

AI Technical Summary

Benefits of technology

This patented technology relieves problems associated with traditional design of an electric wave furnace used within buildings due to its limited ability to efficiently remove excessive thermal energy produced by the device itself without damaging any items or people nearby. By circulating hot air around the devices instead of direct exposure towards them, this helps maintain safe operation while also minimizing overheating issues caused by condensation. Additionally, there may include various fume evacuations systems to help reduce odors emitted from the apparatus' exterior. Overall, these technical improvements enhance the functionality and performance of the electric wavelength range (EW) microswitch boiler).

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency at cooling down microwaves while maintaining good thermal performance for other functions such as food preparations.
