Description

technical field [0001] The invention belongs to the technical field of microwave cooking electric appliances, and more specifically relates to a microwave oven. Background technique [0002] Microwave oven is a kind of modern cook stove that heats food with microwave, has gone into thousands of households now, becomes a kind of necessary kitchen appliance in modern family, yet, existing microwave oven has the following deficiencies: [0003] (1) In terms of consumer use, microwave ovens are currently mainly divided into pull-down door type or side-opening door type figure 1 and figure 2 Shown is a pull-down door-type microwave oven. When cooking food, the food must be put into the microwave oven from the side, and the food must be bent down and lowered to put the food in a suitable position, which is inconvenient and does not conform to the open cooking habits of human beings. The side-opening microwave oven has insufficient transparency caused by the uneven glass silk sc...

Problems solved by technology

[0003] (1) In terms of consumer use, microwave ovens are currently mainly divided into pull-down door type or side-opening door type figure 1 and figure 2 The one shown is a pull-down microwave oven. When cooking food, you have to put the food into the microwave oven from the side. You have to bend over and lower your head to put the food in a suitable position. It is inconvenient and does not conform to the open cooking habits of human beings.

The side-opening microwave oven has insufficient transparency caused by the uneven glass silk screen coating process. The cooking effect of the food cannot be clearly seen after closing the oven door, which will lead to overcooked or overcooked phenomena, because the cooking state of the food cannot be seen , it is easy to make consumers feel afraid of using microwave ovens

[0004] (2) In terms of control panel operation, the main problem is not only the complicated menu operation, but also a few random menus or more than a dozen menus, which cannot satisfy the different dietary differences in various regions of the country (for example: in terms of staple food: rice is the main food in the south. Staple food, pasta is the main food in the north, in terms of dishes: stir-fried dishes are the main food in the south, and stews are the main food in the northeast)

However, the time and power are constant, and the food weight and cooking utensils consumers cannot satisfy, because Chinese consumers are not used to weighing cooking food, water, seasonings and other dishes when cooking, and they are not equipped with standard microwave cooking utensils. The mismatch between the weight, random cooking utensils, fixed time and fixed power will lead to overcooked or overcooked food, unable to cook the taste of traditional diet, which directly determines the cooking effect (taste) of food

[0005] (3) In terms of matching microwave cooking utensils, there is no microwave cooking utensils suitable for microwave environments when cooking food, which is also one of the important reasons for the low frequency of use by consumers. Because there is no microwave cooking utensils, consumers can only use plates or Bowl heating meals directly give consumers the impression that microwave ovens can only heat meals and dishes

[0006] (4) In terms of microwave cooking speed and time, microwave cooking time is twice that of induction cooker (for example: use a 1000W microwave oven and a 1000W induction cooker to heat 1000ml of water with the same weight, the microwave oven takes 12-14 minutes, and the induction cooker takes 5-5 minutes. 7 minutes) Microwave ovens give consumers the perception that heating is too slow and consumes more electricity

[0007] (5) In terms of microwave oven manufacturing, the cavity manufacturing process of microwave ovens at this stage is complicated. The ordinary cavity is generally welded by U board, rear board, front board, top board, waveguide bracket, waveguide, and turntable motor bracket. Stamping The process is complicated and the welding process is complicated. There are many welds and the welds are easy to leak waves and sparks. The investment cost of equipment and molds is high and the maintenance cost is high. It is not convenient for production and installation of unmanned production lines.

[0008] (6) In terms of the application of microwave electromagnetic field transmission technology, the current microwave transmission system is a microwave source (magnetron, semiconductor) that transmits microwaves to the cavity through a waveguide. Excessive leakage will cause radiation hazards to the human body, and will also lead to large microwave losses, low heating efficiency, and problems such as leakage and ignition of waveguide welds.

[0009] (7) In terms of microwave electromagnetic field matching efficiency application technology, since the cavity structure shape and microwave source directly determine the microwave heating efficiency, for example: the current square cavity basically determines the square electric field shape of the microwave in the cavity, and the waveguide port The local deformation and stretching of the stirring plate and the cavity have great limitations on the improvement of the uniformity of the microwave field strength and shape in the cavity, so it will lead to local focus, ignition or wave leakage
