A microwave oven with fast barbecue function comprises a cooking cavity, a high-frequency device and a heating device, wherein the high-frequency device and the heating device are respectively and electrically connected with an I/O interface of a single chip microcomputer in a main controller; the heating device works continuously, and the high-frequency device periodically emits microwaves with adjustable frequency. A parallel circuit composed of a microwave relay RLY2 and a diode D10 of the high-frequency device is connected with a triode TR4 in series, and then is connected with a resistor R27 in series and then is connected with a second I/O interface of the single chip microcomputer. A parallel circuit consisting of a barbecue relay RLY1 and a diode D11 of the heating device is connected in series with a triode TR3, and then is connected in series with a resistor R26 and then is connected with a first I/O interface of the singlechip. When the microwave and the barbecue work simultaneously, the frequency of the microwave can be 30% -50% of the rated output power according to the set program. The food cooked by the utility model has crisp surface, fresh and tender inside, good cooking effect and high cooking speed.
Description
Technical field
The utility model relates to a kind of micro-wave oven, particularly a kind of micro-wave oven with quick baking function.
Background technology
At present, micro-wave oven obtained using widely, and micro-wave oven also has multiple function thereupon: fry function or the like as baking function, steaming because of the high efficiency of its heat food.As disclosing a kind of micro-wave oven among the Chinese patent literature CN2869630Y, comprise the external box of microvave of micro-wave oven with baking function; Be arranged on inside one side of external box of microvave, place the heating cavity for the treatment of cooking food within it on the rotating disk that can be provided with; Be arranged on the inside opposite side of external box of microvave, the electric control chamber of electronic components such as magnetron and high-tension transformer is installed in it; Be installed on the barbecue tube assembly of heating cavity end face and can produce two barbecue tube of emittance; And be arranged on the front and the alternative fire door that opens and closes heating cavity of external box of microvave; It is characterized in that: two barbecue tube comprise a quartz ampoule and an optical wave tube.The micro-wave oven of this structure utilizes quartz ampoule cooking food internal layer, utilizes optical wave tube cooking food top layer, reaches desirable culinary art effect with expectation.But, at first because of microwave oven structure limitation (temperature rise limitation), make that baking function and other function can not be used simultaneously in inner culinary art--microwave function and outside culinary art--, for example: during roast duck, the time that wants to heat is fast, just must turn off microwave power supply again, open baking function and heat earlier with after heating using microwave a period of time.If described microwave function, baking function use simultaneously, then because power is excessive, and it is stronger to generate heat, cause inner other accessory temperature rise of this micro-wave oven too high, the microwave oven surfaces temperature is also very high, and then becomes hidden danger, also fails safety standards.Secondly, because its abnormal Fast Heating, local roasting paste of food will occur and other position is not yet done, promptly heat uneven phenomenon,, greatly reduce cooking food speed and effect owing to two kinds of electro-heat equipments of above reason can not be worked simultaneously always.
The utility model content
The purpose of this utility model be to provide a kind of simple and reasonable, cost of manufacture is low, flexible operation, can realize microwave and barbecue simultaneously heat food, the fast effective micro-wave oven with quick baking function of cooking speed, to overcome weak point of the prior art.
A kind of micro-wave oven with quick baking function by the design of this purpose comprises cooking cavity, high-frequency device and heater, and its architectural feature is that high-frequency device and heater are electrically connected with single-chip processor i/o interface in the main controller respectively; The microwave of frequency adjustable joint is periodically launched in heater continuous operation, high-frequency device.
Parallel circuit and triode TR4 that the microwave relay RLY2 of described high-frequency device and diode D10 form are in series, and after connecting with resistance R 27, connect the 2nd I/O interface of single-chip microcomputer again.
Parallel circuit and triode TR3 that the barbecue relay R LY1 of described heater and diode D11 form are in series, and after connecting with resistance R 26, connect an I/O interface of single-chip microcomputer again.
When the utility model is selected the combination cooking (microwave and baking function are worked simultaneously), single-chip microcomputer the one I/O interface and the 2nd I/O interface send high level signal simultaneously, make triode TR3 and TR4 conducting, barbecue relay R LY1 and microwave relay RLY2 adhesive make barbecue tube and magnetron work together.
When needs were roasted separately, single-chip microcomputer the 2nd I/O mouth sent low level signal, makes triode TR4 be in nonconducting state, and high-frequency device quits work.And this moment, single-chip microcomputer the one I/O interface was still kept high level signal, made that this moment, heater worked independently, and reached to prevent the purpose of food because of the long zoom of microwave heating time.Wherein, when microwave and barbecue when working simultaneously, can be 30%～550% of rated output power according to the frequency of setting program microwave.Not only epidermis is crisp, the inside is fresh and tender through the food of the utility model culinary art, and cook effective, speed is fast.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1-Fig. 4, originally the micro-wave oven that has quick baking function, comprise cooking cavity 1, high-frequency device 2 and heater 3, parallel circuit and triode TR4 that the microwave relay RLY2 of high-frequency device 2 and diode D10 form are in series, after connecting with resistance R 27 again, meet the 2nd I/O interface II of single-chip microcomputer in the main controller 4.Parallel circuit and triode TR3 that the barbecue relay R LY1 of heater 3 and diode D11 form are in series, after connecting with resistance R 26 again, meet an I/O interface I of single-chip microcomputer in the main controller 4, ground connection after barbecue relay R LY1 and the parallel connection of the microwave relay RLY2 other end.When selecting work in combination, but the heater continuous operation, and high-frequency device is periodically launched the microwave of frequency adjustable joint.The metal heat-generating pipe 12,22,32 or 42 of heater can be separately positioned on cooking cavity 1 top, bottom, back or left and right side, sees Fig. 1 and Fig. 5-8, and heater is provided with launched microwave, makes the equally distributed emitting surface of microwave.High-frequency device 2 in the present embodiment also can be arranged on cooking cavity 1 top, bottom, side or back for magnetron.
