Description

Microwave oven

Technical field

The invention belongs to microwave cooking electrical equipment manufacturing technology field, more specifically, relate to a kind of microwave oven.

Background technology

Microwave oven is the modernization cooking kitchen range of a kind of microwave heating of food, has come into huge numbers of families, Become a kind of kitchen appliance indispensable in Modern Family, but, there is following aspect not in existing microwave oven Foot:

(1) in consumer's use, microwave current stove is broadly divided into drop-down gate-type or side opening door Fig. 1 And shown in Fig. 2 for lower sliding door type micro-wave stove, to put into microwave oven from side by food when cooking food, Want croucs that food could be put into suitable position, it has not been convenient to the open culinary art also not meeting the mankind is practised Used., there is uneven the caused transparency of glass silk screen printing coating process not enough in the microwave oven of side opening door, Closing upper furnace door and cannot be clearly visible that the culinary art effect of food, may result in raw or overdone phenomenon, because seeing Lose the cooking status of food, be easy for making consumer produce use of microwave ovens fear.

(2) in terms of control panel manipulation, it is complicated that subject matter is not only menu operation, and random several Individual menu or ten several menus, can not meet the different diet difference in domestic each department (such as: at staple food at all Aspect: south with rice as staple food, the north with wheaten food as staple food, in terms of dish: south based on cooking, Northeast is based on stew).Menu in microwave oven is heat time heating time, standard according to standard in the lab Weight, the power of standard, the cooker of standard repeatedly test constant editmenu, then this is constant Editmenu input is solidificated in the chip of control panel.Therefore, this constant journey is being used in consumer Sequence is it is necessary to meet heat time heating time, heated food weight, rated power, the microwave cookware of coupling. But time and power are constant, food weight and cooker consumer cannot meet, because China disappears Expense person is uncomfortable all to weigh cookings such as cooking food, water, flavoring agent when culinary art, is also not equipped with standard Microwave cookware, random weight, random cooker and not mating between regular time and fixing power, May result in food and cross raw or overdone, it is impossible to cook the taste of traditional food, directly determine food cooking effect Really (mouthfeel).

(3) at the supporting aspect of microwave cooking cooker, the microwave under microwave environment during cooking food, it is not suitable for Cooking utensil, is also to cause consumer to use one of low major reason of frequency, because not having microwave cookware, disappears The person of expense just can only heat food with plate or bowl, and directly allowing consumer produce microwave oven can only the print of hot rice and dish As.

(4) on microwave oven cooking Velocity Time, the cooking time of microwave be the twice of electromagnetic oven (such as: use The microwave oven of 1000W and a 1000W electromagnetic oven, the water of heating identical weight 1000ml, microwave oven is used Time 12-14 divide, 5-7 minute electromagnetic oven used time) microwave oven is to heat too slow and compare to the perception of consumer Take electricity.

(5) at microwave oven manufacture view, the cavity manufacturing process of present stage microwave oven is complicated, common housing one As be by U plate, back plate, header board, top board, waveguide mount, waveguide, rotary tray motor support welding and Becoming, stamping procedure is numerous and diverse, the numerous and diverse weld seam of welding sequence is many and the sparking of weld seam easy leaky wave, equipment and mould Input cost maintenance cost is high, is not easy to unmanned production line and produces installation, and artificial manufacturing cost is high, stored goods Stream cost is high.

(6) in microwave electromagnetic field transmission technology application aspect, existing microwave transmission system is by microwave source (magnetic control Pipe, quasiconductor), through waveguide by microwave transmission to cavity, at microwave during waveguide transmissions, micro- Ripple exceeds standard from weld leakage can cause radiation hazradial bundle to human body, to also result in the big efficiency of heating surface of lossy microwave low, The problems such as waveguide weld leakage sparking.

(7) in terms of microwave electromagnetic field matching efficiency application technology, owing to cavity body structure shape and microwave source are straight Connect and determine microwave heating efficiency, such as: present square cavity determines square in cavity of microwave substantially Electrical field shape, to waveguide mouth, stirring sheet, the local deformation stretching of cavity, to the microwave field density in cavity and The uniformity of shape is improved significant limitation, therefore may result in local focal, sparking or leaky wave.
