Problems solved by technology

[0007] However, existing structures for radiating microwaves have several disadvantages
[0008] The screw cover narrows the microwave channel in the waveguide and thus concentrates the microwaves in an undesired mode, which results in an uneven distribution of the microwaves about the cavity, whereby parts of the cavity are damaged by exposure to strong microwa...

Embodiment Construction

[0025] The microwave oven and its microwave radiation structure of the present invention will be described more fully below with reference to the accompanying drawings.

[0026] figure 1 is an exploded perspective view of a microwave oven according to the present invention.

[0027] refer to figure 1 , the microwave oven includes: a shell forming the appearance of the microwave oven; an oven cavity 20 in which food can be contained; an electronic component box 30 in which electronic components are installed. In addition, an oven door 40 is provided in front of the oven cavity 20 for selectively shielding the oven cavity 20 .

[0028] The structure of the microwave oven will now be described.

[0029] The casing forms the appearance of the microwave oven while covering and protecting the cavity 20 . Therefore, the casing can be made of an iron plate having the required strength. The housing includes an upper plate 11 covering the top and both sides of the cavity 20 , a bas...

Abstract

There is provided a microwave oven. In the microwave oven, a screw covering part is protruded toward an inside of a waveguide for an installation of a motor, a convergence preventing part is formed at a portion of a cavity with a shape corresponding to that of the screw covering part and at a location corresponding to that of the screw covering part, and an elevated portion formed by modifying a portion of the cavity in order to uniformly distribute microwave scattered by a stirrer fan. Therefore, the microwave can be distributed more uniformly about the cavity and thereby food can be cooked more evenly and speedily.

Description

technical field [0001] The present invention relates to a microwave oven, and more particularly, to a microwave radiation structure of a microwave oven, in which microwaves can be more effectively distributed in a cavity, thereby enabling a user to cook food conveniently and uniformly. Background technique [0002] A microwave oven is a cooking device that cooks food by passing microwaves through it. Microwave ovens use a magnetron to convert electrical current into microwaves. [0003] Generally, a microwave oven radiates microwaves generated by a magnetron to food when electric current is applied to electronic components of the microwave oven, thereby heating the food. [0004] Such microwave ovens can be divided into domestic microwave ovens with smaller magnetrons and commercial microwave ovens with larger (or more) magnetrons. Microwave ovens can also be classified according to the heating method, namely the glass tray method that turns the food and the agitating fan ...
