Abstract
The utility model relates to an electric pressure cooking pot with a pressure relief mechanism to control pressure including an inner pot, a pot cover, and a pressure control device which controls heating by the combination of a thermistance temperature-sensing part and an electric control part. The utility model is characterized in that the electric pressure cooking pot is provided with a pressure relief device. The pressure relief device is a relief valve, which is arranged on the pot cover. The relief valve includes a relief valve cover, a relief valve core, a relief valve spring, and a sealing silica gel ring. The relief valve core and the sealing silica gel ring are assembled together and can slide vertically. The upper end of the relief valve spring pushes against the inner surface of the relief valve cover and the lower end of the relief valve spring is coated on the relief valve core. The relief valve over is locked on the pot cover through a snail. The pot cover is provided with an air hole and a channel for pressure relief. The pressure control device which controls heating by the combination of the thermistance temperature-sensing part and the electric control part is controlled and connected with a heating disk and an electromagnetic valve. Under the states that the way of controlling pressure by the thermistance temperature-sensing part and the electric control part is out of work and the way of controlling pressure by the relief valve is also out of work, the pressure relief structure plays a role of making the pressure in the pot below the safe pressure so as to make the electric pressure cooking pot much safer to be used.
Description
Technical field
The utility model relates to a kind of electric pressure cooking saucepan that has the pressure relief mechanism controlled pressure.
Background technology
At present, the pressure control mode of electric pressure cooking saucepan has two kinds basically on the market, guarantees pot inner pressure safety, a kind ofly is: thermistor temperature-sensitive+automatically controlled control section, and the control heating state is controlled pot inner pressure; A kind ofly be: pot inner pressure is controlled in the open and close of pressure limiting valve.These two kinds of controlled pressure modes only are controlled in pot inner pressure under the operating pressure about 80kPa.But when the thermistor inefficacy, after pressure limiting valve was blocked, pot inner pressure will rise rapidly, if having only this dual mode to control pot inner pressure, electric pressure cooking saucepan is just dangerous.
The utility model content
The purpose of this utility model provides a kind of electric pressure cooking saucepan that has the pressure relief mechanism controlled pressure, being intended to thermistor lost efficacy, after pressure limiting valve is blocked, pot inner pressure rises rapidly, after surpassing safe pressure, pressure-relief valve structure action makes pot inner pressure be controlled under the safe pressure of the 140kPa left and right sides, make electric pressure cooking saucepan safer, more reliable, use more relieved.
Foregoing of the present utility model adopts following technical scheme to be achieved:
A kind of electric pressure cooking saucepan that has the pressure relief mechanism controlled pressure comprises interior pot, pot cover, by the pressure control device of thermistor temperature-sensitive and grouping of automatically controlled control part and control heating, and its special character is: described electric pressure cooking saucepan is provided with pressure relief device.
Described pressure relief device is a relief valve.
Described relief valve is arranged on the pot cover.
Described relief valve comprises pressure release valve gap 1, pressure releasing valve core 3, relief valve spring 2, sealed silicon cushion rubber 4, pressure releasing valve core 3 and sealed silicon cushion rubber 4 fit together, can move up and down, relief valve spring 2 upper ends withstand on pressure release valve gap 1 inner surface, the lower end is enclosed within on the pressure releasing valve core 3, and its effect is that restriction pressure releasing valve core 3 moves up.
Pressure release valve gap 1 is locked on the pot cover 5 by screw, and the pore and the passage of pressure release arranged on the pot cover 5.
Because the utility model has adopted technique scheme, can have following effect: promptly work as:
A. thermistor temperature-sensitive+automatically controlled control heating controlled pressure is the mode about 80kPa, or
B. be after mode about 80kPa all lost efficacy at the pressure limiting valve controlled pressure, pot inner pressure rises rapidly, when pot inner pressure surpasses safe pressure about 140kPa, the pot inner pressure that this moment, sealed silicon cushion rubber 4 lower surfaces were born is greater than the elastic force of top spring 2, sealed silicon cushion rubber 4 will be backed down, air pressure will upwards be revealed from pot cover 5 pores, realizes the pressure release function; After pot inner pressure dropped under the safe pressure, the pot inner pressure that sealed silicon cushion rubber 4 lower surfaces bear was less than the elastic force of upper surface spring 2, and sealed silicon cushion rubber 4 can be closed pot cover 5 pores again, and pressure release is finished; During pressure release, have a large amount of gas and emerge between pot cover and top cover, the user will find this abnormal conditions immediately, can pull out power supply and stop heating, also not have safety problem even this situation occurs, but if there is not this pressure relief mechanism, gas will rise always in the pot, and the danger of blast is arranged.
Obviously, the utility model can prevent that blast from taking place.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
A kind of electric pressure cooking saucepan that has the pressure relief mechanism controlled pressure comprises interior pot, pot cover, by the pressure control device of thermistor temperature-sensitive and grouping of automatically controlled control part and control heating, and its special character is: described electric pressure cooking saucepan is provided with pressure relief device.
Described pressure relief device is a relief valve.
Described relief valve is arranged on the pot cover.
Described relief valve comprises pressure release valve gap 1, pressure releasing valve core 3, relief valve spring 2, sealed silicon cushion rubber 4, pressure releasing valve core 3 and sealed silicon cushion rubber 4 fit together, can move up and down, relief valve spring 2 upper ends withstand on pressure release valve gap 1 inner surface, the lower end is enclosed within on the pressure releasing valve core 3, and its effect is that restriction pressure releasing valve core 3 moves up.
Pressure release valve gap 1 is locked on the pot cover 5 by screw, and the pore and the passage of pressure release arranged on the pot cover 5.When:
A. thermistor temperature-sensitive+automatically controlled control heating controlled pressure, promptly the mode about 80kPa or
B. at the pressure limiting valve controlled pressure, be after mode about 80kPa all lost efficacy, pot inner pressure rises rapidly, when pot inner pressure surpasses safe pressure about 140kPa, the pot inner pressure that this moment, sealed silicon cushion rubber 4 lower surfaces were born is greater than the elastic force of top spring 2, sealed silicon cushion rubber 4 will be backed down, and air pressure will upwards be revealed from pot cover 5 pores, realizes the pressure release function; After pot inner pressure dropped under the safe pressure, the pot inner pressure that sealed silicon cushion rubber 4 lower surfaces bear was less than the elastic force of upper surface spring 2, and sealed silicon cushion rubber 4 can be closed pot cover 5 pores again, and pressure release is finished; During pressure release, have a large amount of gas and emerge between pot cover and top cover, the user will find this abnormal conditions immediately, can pull out power supply and stop heating, also not have the danger problem even this situation occurs, but if there is not this pressure relief mechanism, gas will rise always in the pot, and the danger of blast is arranged.
