Microwave oven

Abstract

The invention relates to a microwave oven with the structure which makes outside air sucked from back recycling inside the microwave oven and then being discharged from front lower end. In the invention, a plurality of air inlets are formed at one side of a back panel of the microwave oven; a fan assembly is arranged at right upper end of a cavity assembly corresponding to front of said air inlets along fore and aft direction. So outside air flows into a first passage formed at right side of the cavity assembly by said air inlets, then moves to upside of the cavity assembly under the action of said fan assembly, consequently, keeps various electronic units and heaters radiating, and afterwards, flows into a second passage formed at left side of the cavity assembly. After the air flows into a lower passage communicated with lower end of said second passage, it will be discharged to exterior by air outlets in front of the lower passage finally.

Description

technical field [0001] The present invention relates to a microwave oven (A micro wave oven), more specifically, relates to a microwave oven having the following characteristics: a fan assembly can be used to promote air for cooling electronic components and heaters inside the microwave oven to the microwave oven. Flow inside and outside. Background technique [0002] There are multiple models and types of microwave ovens sold in the market, and they are generally used on the table. But a kind of built-in type (built-in type) microwave oven has appeared recently, can be built in the kitchen furniture, thereby presents the overall aesthetic feeling together with the kitchen furniture. [0003] figure 1 with figure 2 The main structure of the built-in type microwave oven adopting the prior art is shown. As shown in the figure, in a built-in microwave oven (hereinafter referred to as a microwave oven), a space for heating food—a cooking chamber 11 is formed inside a cavity...

AI Technical Summary

Problems solved by technology

[0019] In existing microwave ovens, in order to form an air flow capable of dissipating heat from various electronic components or heaters inside, several fan assemblies 13a, 25, 35, 37 need to be installed, thereby not only increasing the manufacturing cost of the microwave oven, but also When the above-mentioned fan assemblies 13a, 25, 35, 37 are driven, a lot of noise will be produced

[0020] In addition, since the above-mentioned intake grill 21 and exhaust grill 23 for sucking and discharging air are all installed in front of the microwave oven, the configuration of the front of the microwave oven is limited to a certain extent.
