Usually, the frictional heat that friction produced between the particle of the formation of the foods using in micro-wave oven food obtains the heating and the cooking.
What describe now is the method for cooking control according to the weight sensor in the conventional microwave oven.
For example in gastronomical process, select the food defrosting of automatic-cooking by keyboard input block (not shown), input cooking beginning, the keyboard input block is exported to controller 15 with corresponding keyboard signal, weight sensor 8 detects the weight of food 1, and the corresponding signal that measures is exported to controller 15.
The weight that controller 15 measures according to weight sensor 8 is calculated the cooking time, and exports to rotary tray motor 4, magnetron 6 and cooling fan motor 11 respectively according to the control signal that keyboard signal will be used to drive rotating disk 2, magnetron 6 and cooling fan motor 11.
Then, rotary tray motor 4 rotates rotating disk 2, and this magnetron 6 produces microwave and cooling fan motor 11 rotates cooling fan 7.
Food 1 rotates along with the rotation of rotating disk 2, and magnetron 6 obtained cooling when cooling fan 7 rotated.The food 1 that rotates is subjected to the heating and the cooking of microwave, and these microwaves are radiated in the cooking room 5 by waveguide 5.
Controller 15 is started the clock when magnetron 6 is subjected to encouraging, if the time of calculating surpasses the cooking time of calculating, will make rotating disk 2, magnetron and cooling fan 7 control signals out of service be exported to rotary tray motor 4, magnetron 6 and cooling fan motor 11 respectively respectively.
Then, rotary tray motor 4 stops the rotation of rotating disk 2, and cooling fan motor 11 stops the rotation of cooling fan 7, and magnetron 6 stops to produce microwave, has so just finished whole cooking campaign.
But, the existing problem of method of cooking control according to the weight sensor of conventional microwave oven is: food is to heat according to the cooking time of calculating and cook according to the weight of food, it does not consider the state of food, whether does not for example consider frozen food.
Simultaneously, although top method describes is to utilize the weight sensor of traditional micro-wave oven to cook the method for control, the method that other gas sensor that utilizes conventional microwave oven is cooked control also can be described in conjunction with Fig. 1.
When having selected gastronomical process (for example heating process of automatic-cooking) and imported the signal of cooking at the beginning, the keyboard input block is exported to controller 15 with corresponding keyboard signal.

Then, rotary tray motor 4 rotates rotating disk 2, and magnetron 6 produces microwave, and cooling fan motor 11 rotates cooling fan 7.
Food 1 rotates along with the rotation of rotating disk 2, and magnetron 6 is along with the rotation of cooling fan 7 obtains cooling, and along with microwave is given cooking room 3 by waveguide 5 radiation, the food 1 of rotation is heated and cooks.
At this moment, gas sensor 10 detects the gas flow of discharging by outlet 9, and the relevant detection signal exported to controller 15, the initial gas scale of construction that this controller detects according to gas sensor 10 is again calculated the reference gas scale of construction (for example 75% of the initial gas scale of construction) successively.
Controller 15 judges whether the gas flow that gas sensor 10 detects reaches the reference gas scale of construction, if gas flow has reached the reference gas scale of construction, then the gastronomical process that provides according to following table 1 judges whether surpass the maximum reference time (600 seconds) of gastronomical process coefficient and maximum reference time data computing time.

Then, rotary tray motor 4 rotates rotating disk 2, and magnetron 6 produces microwave, and cooling fan motor 11 rotates cooling fan 7.
Food 1 rotates along with the rotation of rotating disk 2, and magnetron 6 is along with the rotation of cooling fan 7 obtains cooling.Along with microwave is given cooking room 5 by waveguide 5 radiation, the food 1 of rotation is heated and is cooked.
When controller 15 is started the clock, magnetron 6 is activated, if the time of calculating surpasses the cooking time of user's input, then respectively control signal is exported to rotary tray motor 4, magnetron 6 and cooling fan motor 11, so that rotating disk 2, magnetron 6 and cooling fan 7 are stopped operating, and will inform that cooking the control signal of finishing exports to buzzer (not shown) and display unit (not shown) respectively.
And then rotary tray motor 4 and cooling fan motor 11 stop operating, and magnetron 6 stops to produce microwave simultaneously, and buzzer sends the information that the display unit demonstration cooking is finished when cooking the sound of finishing, whole like this cooking end of run.
