Description
Technical field
The utility model relates to a kind of electric pressure cooking saucepan that has pressure control device.
Background technology
At present, the pressure control of electric pressure cooking saucepan all is to adopt closed-in construction mostly, and when in the pot pressure being arranged, pot can be out of shape or displacement, control centre controls the pressure in the pot by detecting the distortion or the displacement of pot, and its method is fairly simple, but pressure control is inaccurate, the culinary art effect is bad, not exclusively, and the cost height.
The utility model content
Inaccurate in order to overcome existing electric pressure cooking saucepan pressure control, the culinary art effect is bad, dangerous, defect of high cost, the utility model provides a kind of pressure control method of new electric pressure cooking saucepan, the most important thing is that this method pressure control is more accurate, can be according to different menu control pressure to different values, the culinary art better effects if, safer, cost is lower, can also prevent empty the burning.
A kind of electric pressure cooking saucepan that has pressure control device, comprise a pot body, loam cake, heater members, heating cavity and electric control gear thereof, it is characterized in that: be provided with the temperature-detecting device by electric control gear control in the pot body, a user interface that links to each other with the M of control centre of electric control gear is arranged at a pot surface.
Described temperature-detecting device is a thermistor.
According to the utility model, its special character is: the core control circuit of described electric control gear as shown in Figure 1, comprise the M of control centre, for example model is the control chip of S3C (F) 9488, S3C9228, HMS80F (P, C) 733K, HMS87C1404 (8), ATMEGA16, the power circuit P, the temperature sensing circuit ST that link to each other with the M of control centre, anti-jamming circuit K, heating control circuit C, reaches the heater element H that is connected with heating control circuit C.
According to the utility model, its special character is: also can according to circumstances add auxiliary circuits such as abnormal alarm circuit, mu balanced circuit, timing control circuit on the M of control centre certainly.
According to the utility model, its special character is: the M of control centre is connected with user interface, comprising: LCD or LED, button or turn-knob etc., described user interface is arranged at the surface of pot body.
Because the utility model has adopted technique scheme, after energising and the startup, entire circuit is started working, power circuit P uninterruptedly provides power supply for system, temperature sensing circuit ST detects the temperature of pot in real time, according to configuring different pressure in the different editmenus in advance, when pressure was higher than setting value, M can control heating control circuit C, reduce or disconnection output, when pressure slowly drops to setting pressure when following, M can control heating control circuit C, increases output, make the heater element heating more, thereby can be timely, controlled pressure is to different value, so that the better effects if of culinary art is safer exactly.

The specific embodiment
Below in conjunction with the specific embodiment in detail the utility model is described in detail:
A kind of electric pressure cooking saucepan that has pressure control device, comprise a pot body, loam cake, heater members, heating cavity and electric control gear thereof, it is characterized in that: be provided with the temperature-detecting device by electric control gear control in the pot body, a user interface that links to each other with the M of control centre of electric control gear is arranged at a pot surface.
Described temperature-detecting device is a thermistor.
According to the utility model, its special character is: the core control circuit of described electric control gear as shown in Figure 1, comprise the M of control centre, the M of control centre is selected from any one in the control chip that model is S3C (F) 9488, S3C9228, HMS80F (P, C) 733K, HMS87C1404 (8), ATMEGA16, power circuit P, the temperature sensing circuit ST that links to each other with the M of control centre, anti-jamming circuit K, heating control circuit C, and the heater element H that is connected with heating control circuit C.
According to the utility model, its special character is: also can according to circumstances add auxiliary circuits such as abnormal alarm circuit, mu balanced circuit, timing control circuit on the M of control centre certainly.
According to the utility model, its special character is: the M of control centre is connected with user interface, comprising: LCD or LED, button or turn-knob etc., described user interface is arranged at the surface of pot body.
As accompanying drawing 2, shown in 3, after the energising, the user can select needed menu by demonstration and operation interface, after the startup, entire circuit is started working, MCU exports to heating control circuit and controls the heating element heater heating, temperature sensing circuit detects the temperature of pot in real time, after being heated to certain hour, when kettle temperature arrives the pressure set points of selected menu, MCU can control heating control circuit, reduce or disconnection output, when pressure slowly drops to setting pressure when following, MCU can control heating control circuit, increase output, make the heater element heating more, thereby can be timely, controlled pressure is to different value exactly, so that the better effects if of culinary art, safer: when not adding just startup heating of water in pot, at this moment pot is can not to be out of shape or to be shifted, and conventional method can not detect, and the temperature of pot can very fast rising, temperature inductor just can induce, and information in time pass to MCU stop the heating, send the alarm user and add water, can prevent the generation of accidents such as fire effectively.
The power circuit P that links to each other with the M of control centre, temperature sensing circuit ST, anti-jamming circuit K, heating control circuit C, and and heating control circuit C and other auxiliary circuit all adopt prior art.
