Description

Chinese microwave oven control panel

Technical field

The present invention relates to kitchen mess kit parts, specifically is a kind of Chinese microwave oven control panel.

Background technology

Microwave oven is to utilize the microwave of the 2450MHZ that magnetron produces to reflect in furnace chamber and act on food and make the molecule in the food produce shake altogether, thereby the equipment of molecule phase mutual friction generation heat cooking food, in recent years, except the magnetron thermal source, be provided with the heating source of barbecue tube etc. in the microwave oven again, as shown in Figure 1, existing microwave oven generally is made of following several parts: the rotating disk 11 of placing food, generate electromagnetic waves and supply to the magnetron 12 of food in the furnace chamber 10 by waveguide, the fan 13 of cooling magnetron 12, be installed on the barbecue tube 15 of furnace chamber roof, be installed on the infrared ray sensor 14 of sidewall detection food cooking temperature, the microcomputer of sensor-lodging is according to the controller (not drawing among the figure) of sensor signal control magnetron and barbecue tube.

The microwave oven circuit of existing general charged brain as shown in Figure 2, it includes: by gate controlled switch kd, rotating disk, fan electromotor DF, microcomputer MC, the transformer T of key switch kd ' control power supply, the magnetron 12 of being supplied with filament voltage and high-voltage power supply by transformer secondary output constitutes, the dc high-voltage source of magnetron is formed by high-tension transformer secondary coil, diode D and resistance R 1, capacitor C 3 voltage multiplying rectifiers, and microcomputer is again according to its keyboard input program, Data Control control circuit relay switch K1, K2 control cooking time and cooking firepower.

Above-mentioned existing microcomputer comprises input, output and execution control section, the importation is made of capacitance touch type keyboard and the input interface chip (as TM-1976) that is mated, keyboard can be imported various operational order data, after encoding, input interface chip transports to microcomputer chip (as TMS-1000), user program then uses mask technology to write in the read only memory ROM as requested, the microcomputer output shows that by the group of four figures pipe timing controlled of operating part is passed through circuit by program that deposits single-chip microcomputer in or data, the heating time and the heating power of relay switch controlled microwave stove.

Existing microwave oven panel selection, input cooking time and power setting have two kinds of forms, a kind of is that the upper and lower position of right panel is provided with cooking regularly knob and power (firepower) knob, arrange kind, quantity and the specification explanation of food when the user uses as required and set cooking time and cooking power with above-mentioned knob, the microwave oven of this mode wants to have arranged food and must keep the introduction of microwave oven specification firmly in mind and operate knob according to practical experience; Another form is that many buttons are set on the microwave oven right panel, each button configure cooking power and cooking time by producer according to the cooking experience of different foods and quantity and on button with picture and text indicate various names of the dish for users' choosing by, but because staple food and menu are various, make number of keys increase, cause that the button area is very little, keyboard is complicated mixed and disorderly, as staple food steamed bun, bread, rice, boiled dumpling, soup class, noodles, congee, gruel, various steamings, boil, burn, roasting menu is numerous is unequal to lifting, cause during use select inconvenience in addition take place wrong by.

Summary of the invention

The present invention provides a kind of and has only a menu acknowledgement key, four page turning keys and some numerical keys and adopt LCDs to show in the selected cooking the perhaps Chinese microwave oven control panel of menu for solving the problem that exists in the above-mentioned known technology.

Its structure of technical scheme that the present invention takes for the problem of the above-mentioned existence of solution includes: there is the cabinet of door the front, be contained in the furnace chamber in the cabinet, be installed on the rotary tray motor of furnace chamber bottom, be arranged at the rotating disk on motor and the wheel rim, be installed on the panel on machine box door right side, be installed on the gate controlled switch and the key switch of panel, be installed on the microcomputer of panel inboard by gate controlled switch and key switch control power supply, rotating disk, fan electromotor, the power transformer of magnetron, it is characterized in that: its panel is equipped with and is connected to the microcomputer input interface, page turning key and acknowledgement key that can convers ion menu, microcomputer chip interface be connected with external memorizer and connect LCDs through slow treasure and show various menus with Chinese character.

About being equipped with on the panel around the above-mentioned menu acknowledgement key, about four page turning keys.

Also be equipped with on the panel of the present invention and be connected to the microcomputer input interface, assisted Selection input cooking menu also can be used for setting the numerical key of cooking date and time.

Advantage and good effect: have following advantage with existing control panel of microwave oven comparison the present invention:

A. the present invention with Chinese character and digital display menu, by the page turning key convers ion menu, is confirmed by acknowledgement key that with LCDs the display menu number is increased, and the area of display menu increases, and makes the user come into plain view to be convenient to set to menu and selects.

B. Chinese microwave oven control panel simplicity generosity of the present invention, easy to operate.

But panel C. of the present invention is also installed numerical key assisted Selection input cooking menu, also can select to set cooking date and time.
