Description
Technical field
The present invention relates to a kind of frequency-conversion microwave oven, specifically a kind of fire with Freehandhand-drawing heating power curve frequency-conversion microwave oven
Power adjusting method.
Background technique
Micro-wave oven is the cooking appliance heated using microwave to food, to reach preferable culinary art effect, is often needed
Different heating firepower is set in the different phase in entire cooking process, such as needs moderate heat, second-order in the first stage
Section needs strong fire, phase III to need weak fire, this just needs to be arranged in entire cooking process a variety of different output powers.
Conventional microwave oven is to determine frequency micro-wave oven, it is to export constant power with 50 hertz of fixed frequencies, if necessary to defeated
Different capacity out, can only be long by frequently periodically opening and closing the time interval of power supply and setting electric power on/off
Short to simulate control output power, this microwave energy that will lead to output is desultory, and built in general micro-wave oven
Food is placed on the rotation on turntable, this may will appear: when power switch is opened, the first part of food is turned to
The biggish place of microwave energy, the microwave energy of absorption is more, and second part is not in the lesser place of microwave energy, the microwave energy of absorption
It is less;It is just that the first part of food turns to the biggish place of microwave energy again when opening power supply again after closing power supply, the
Two are partially in the lesser place of microwave energy, finally will appear and are heated the somewhere of food and are repeated heating, and another place adds
The insufficient non-uniform phenomenon of heat.Meanwhile conventional microwave oven the shortcomings that changing the mode of output power that there are noises is big, not power saving.
Currently, some producer develops frequency-conversion microwave oven, needed for being transformed into the supply frequency of alternating current 50Hz
Frequency realize required microwave output power, it is realization different output power and frequent for determine frequency micro-wave oven relative to tradition
Transformed lasting output power and lasting may be implemented in the desultory microwave energy of ON/OFF power supply, frequency-conversion microwave oven
Microwave energy, thus the effect of Omnibearing even heating, the food cooked can be realized constantly incessantly to heat foods
Object mouthfeel is more preferable;Noise is small simultaneously, more energy saving.
Referring to Fig. 1, although there is the micro-wave oven of many converter techniques on the market at present, output work can be changed by frequency conversion
Rate simultaneously generates lasting microwave energy, but can only generally realize the output power setting individually changed, working principle such as Fig. 1 institute
Show, multiple output power options are provided on control panel of microwave oven, these output power options pass through converter technique
It realizes, when needing moderate heat to heat, user can press the button of 400W option, and control module will receive the signal of the power simultaneously
Operational order is issued, so that the output power for controlling magnetron is 400W;When being heated to need to change into strong after a certain period of time
Fire, at this time, it may be necessary to which user presses the button of 1000W option again;When being again heated to after a certain period of time, need to be changed to weak fire,
At this time, it may be necessary to user presses the button of 100W option again, thus, operation is extremely inconvenient, and midway even can be forgotten to replace defeated
Power out, the experience that continuous power cannot be brought to change to consumer well.Therefore, it is further improved.
Summary of the invention
The purpose of the present invention is intended to provide a kind of structurally reasonable, and cost is relatively low, draws flexibly, effectively solution frequency-conversion microwave oven
Realize the problem of different firepower adjust heating food, that improves user's culinary art experience has Freehandhand-drawing heating power curve variable frequency microwave
The firepower adjusting method of furnace, to overcome shortcoming in the prior art.
