Problems solved by technology

Due to the limitation of the shape of the box body, the microwave oven with this type of structure makes the utilization rate of the cooking chamber not high, and considering that the overall volume of the microwave oven should not be too large, the size of the cooking chamber is often limited, and because the door is arranged in the cooking chamber. the front of the compartment, making it very inconvenient to put in and take out food
[0003] Chinese Patent Literature No. CN2898661Y disclosed a microwave oven on May 9, 2007, including a microwave oven shell, a window, a door for covering the window, and a handle on the door. The shell of the microwave oven and its inner wall are in a hemispherical shape. Although the microwave oven saves space, considering the problem of microwave shielding, the use of multiple covers also increases the difficulty of manufacturing

Abstract

The invention discloses a door structure of a microwave oven. The door structure comprises an outer hood, a microwave shielding hood and an inner hood which are arranged from outside to inside in sequence, and further comprises a framework, wherein the outer hood, the microwave shielding hood and the inner hood are assembled together through the framework; a choke groove is formed in the framework; the microwave shielding hood is provided with turned edges; the microwave shielding hood is connected with the framework in a pressing mode through the turned edges; the inner hood is provided with convex edges; the inner hood is embedded on the framework through the convex edges; and the framework is provided with an assembling groove and / or assembling edges. The convex edges are arranged on the outer side of the inner hood; the microwave shielding hood takes the shape of a helmet; the cross section of the microwave shielding hood adopts a U-shaped, arch bridge-shaped, semicircular or elliptic structure matched with the cross section of the inner hood; and a plurality of mesh holes are formed in the surface of the microwave shielding hood, and take the shapes of hexagons. The door structure has the characteristics of being simple and reasonable in structure, low in manufacturing cost, high in security degree, high in heat efficiency and capable of effectively preventing microwave leakage.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a microwave oven door structure. Background technique [0002] Most of the traditional microwave ovens have a box-shaped main body, including a box-shaped cooking chamber, a plate-shaped door body, and an electrical appliance room positioned on one side of the cooking chamber. The cavity of the microwave oven is formed by a layer of metal wrapping, the magnetron is placed on the side of the cavity, and the magnetron emits microwaves from the side of the cavity into the cavity. Due to the limitation of the shape of the box body, the microwave oven with this type of structure makes the utilization rate of the cooking chamber not high, and considering that the overall volume of the microwave oven should not be too large, the size of the cooking chamber is often limited, and because the door is arranged in the cooking chamber. The front of the compartment makes it very inconvenient to put in and ...
