Microwave oven with air-exhausting function

Abstract

The microwave with exhaust function is formed from oven cavity for cooking food, hot air convection heater group mounted on one sideof oven cavity, electric field device for generating wirowave and ventilator unit, the electric field device is mounted on the mounting plate whose height is identical to that of top surface of oven cavity, and the ventilator unit is positioned in the upper portino of oven cavity. It cna uniformly heat food on the tray in the over cavity, and save cooling fan unit for cooling electric field device.

Description

1. Technical field: [0001] The invention relates to a microwave oven, in particular to a microwave oven with an exhaust function. 2. Background technology: [0002] So far, various heating devices for heating food have been developed. The most primitive heating appliance is to contact the container holding the food with the heat source to achieve the purpose of heating and cooking. Afterwards, a variety of cooking devices that directly or indirectly utilize electric energy have been developed, and microwave ovens that use microwaves as a heating source are one of them. However, conventional microwave ovens cannot provide fast and high-quality cooking due to the limitation of single microwave heating and heat release; for this reason, a heater as an auxiliary heat source is installed on the upper or lower part of the oven cavity. When the microwave oven with this auxiliary heat source and exhaust function is installed on the top of the oven gas stove, it will have the funct...

AI Technical Summary

Problems solved by technology

[0005] But still there are some weak points in the microwave oven of above-mentioned structure, and need to improve

First of all, when food is placed on the bracket 33 for heating, the high-temperature airflow produced by the hot air convection heater group 20 cannot be well passed to the bottom of the oven cavity 1 because of the obstruction of the food placed on the bracket 33, so it cannot Heat food evenly; for example, when baking biscuits, one part is often burnt due to overheating, while the other part is undercooked due to insufficient heating

Secondly, the electric field device is far away from the power supply, and its connecting wires are long, which not only complicates the assembly, but also increases the production cost accordingly

Third, due to multiple fan groups, the microwave oven is noisy and complicated to assemble
