Microwave oven

Abstract

The invention relates to a microwave oven, which comprises an oven base, a bonnet hinged with the oven base and a cooking chamber enclosed by the oven base and the bonnet, wherein the bonnet comprises a waterproof cover, a microwave shielding cover and an outer cover which are sequentially arranged from inside to outside, the waterproof cover, the microwave shielding cover and the outer cover are respectively in a semisphere shape and are assembled together via a bonnet skeleton and a skeleton frame. The bonnet skeleton comprises an annular base body, the inner side of the base body is provided with an assembly groove, the waterproof cover is embedded in the assembly groove, and the microwave shielding cover is pressed on the base body. The outer edge of the waterproof cover is provided with a first flanging, the waterproof cover is embedded in the assembly groove via the first flanging, the outer edge of the microwave shielding cover is provided with a second flanging, and the microwave shielding cover is pressed on the base body via the second flanging. The skeleton frame is sleeved on the outer side of the microwave shielding cover and is pressed on the second flanging of the microwave shielding cover and the bonnet skeleton. The invention has the characteristics of flexible operation, low manufacturing cost and great increase on the utilization rate of the cooking chamber.

Description

technical field [0001] The invention relates to a microwave oven. Background technique [0002] Conventional microwave ovens, such as figure 1 As shown, its main body is mostly box-shaped, including a box-shaped cooking chamber 21 and a plate-shaped door body 22, and an electrical room located on one side of the cooking chamber 21. The oven cavity is formed by a layer of metal wrapping, and the magnetron 20 is placed On the side of the oven cavity, the magnetron 20 emits microwaves from the side of the oven cavity into the oven cavity. The microwave oven of this kind of structure is owing to being limited by the box shape, makes the utilization rate of cooking chamber 21 not high, and considering the overall volume of microwave oven should not be too large, so the size of cooking chamber 21 is also often restricted, and because door body 22 It is arranged in front of the cooking chamber 21, which makes it very inconvenient to put in and take out food.

Problems solved by technology

The microwave oven of this kind of structure is owing to being limited by the box shape, makes the utilization rate of cooking chamber 21 not high, and considering the overall volume of microwave oven should not be too large, so the size of cooking chamber 21 is also often restricted, and because door body 22 It is arranged in front of the cooking chamber 21, which makes it very inconvenient to put in and take out food

[0003] Chinese Patent Document 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, it still has a furnace door on its hemispherical furnace body.

When the heating conditioner is in the open state, the lids overlap each other and cannot be fully opened, which makes it difficult to take and place food; in addition, considering the problem of microwave shielding, the use of multiple lids also increases the difficulty of manufacturing
