Micro-wave oven

Abstract

The invention discloses a microwave oven which comprises an oven chamber, a power distribution chamber, a magnetron, and an oven chamber upper cover provided thereon with a spherical surface raised towards the interior of the oven chamber. The magnetron is arranged on a side plate of the oven chamber in a way that a microwave-emitting antenna on the magnetron is aligned with the focus of the spherical surface. A magnetron shell envelopes the magnetron inside and is arranged on the side plate of the oven chamber. A magnetron holder inside the magnetron shell has a non-uniform thickness, so that a microwave-emitting antenna on the magnetron shell is inclined upwards. Alternatively, a tapered magnetron shell fixing supporter is arranged between the side plate of the oven chamber and the magnetron shell, to allow the magnetron shell to be inclined upwards. Since the microwave is scattered to heat foods in all directions, the invention prevents the dead area of microwave cooking, avoids the non-uniform heating of foods due to the influence of microwave distribution on foods, increases the cooking speed and microwave efficiency, and prolongs the service life of magnetron.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a microwave oven capable of uniform distribution of microwaves in the cooking process of the microwave oven and making the food cooking more uniform, delicious and delicious. Background technique [0002] A microwave oven is a device that uses electric current to generate microwaves and irradiates the microwaves in food to heat the food. It can heat the surface and inside of the food at the same time, and can quickly cook a variety of foods. [0003] In order for the microwave oven to cook food in various cooking methods, the output power needs to be adjusted according to the user's requirements. As an output power adjustment device, a knob is usually used. [0004] Such as figure 1 As shown in FIG. 2 , the conventional microwave oven has a rectangular parallelepiped shape, and its top surface and appearances on the left and right sides are formed by a case. A furnace cavity 1 is formed ins...

AI Technical Summary

Problems solved by technology

[0012] The common deficiency of the prior art is that it only considers the microwave distribution when there is no food, but does not take into account the impact on the microwave distribution due to the existence of food volume after adding food

[0013] Glass disk rotation mode: the microwave distribution is relatively uniform on the concentric circle centered on the rotating shaft, but the distribution along the radial direction is uneven

[0014] Glass plate swing mode: microwave distribution is relatively uniform in the direction of glass plate swing, but uneven in the direction perpendicular to the swing direction
