Fig. 1 is circuit diagram of the present utility model.
[specific embodiment]
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:
As shown in Figure 1, a kind of pressure sensitive energy saving control circuit device of electric pressure cooking saucepan, include the electric pressure cooking saucepan heater element H that is connected in series on the power circuit, the temperature limit switch T1 that is used for anti-high temperature, the the first pressure switch S1 that is used for anti-high pressure, and power supply indicator circuit 1, described heater element H two ends are parallel with big fire indicator light circuit 3, it is characterized in that described power supply indicator circuit 1 two ends are parallel with by timer switch K and are used for control heater element H enters working control circuit energy saving pattern whether the second pressure switch S2 is composed in series, thereby described the second pressure switch S2 two ends are parallel with and are disconnected the Current Limiting Diodes D2 that makes heater element H be operated in the energy saving pattern for triggering at the second pressure switch S2, and described Current Limiting Diodes D2 two ends are parallel with the energy-saving indicating lamp circuit 2 that shows when entering the energy saving pattern at electric pressure cooking saucepan.
It is inner that aforesaid temperature limit switch T1, the first pressure switch S1, the second pressure switch S2 are arranged on the bottom of a pan of electric pressure cooking saucepan, is that switch is communicated with when not triggering, and disconnects and trigger when reaching trigger condition.
Generally for electric pressure cooking saucepan, if temperature surpasses 170 ℃ of accidents that meet accident easily, therefore in the present embodiment, when being arranged on 165 ℃, triggers described temperature limit switch T1 disconnection.
Trigger when aforesaid the first pressure switch S1 is arranged on 80kPa and disconnect.
Trigger when aforesaid the second pressure switch S2 is arranged on 50kPa and disconnect.
Power supply indicator circuit 1 is connected in series by diode D1, power supply indicator L1 and resistance R 1 and forms as mentioned above.
Big fire indicator light circuit 3 is connected in series by diode D3, big fire indicator lamp L3 and resistance R 3 and forms as mentioned above.
Energy conservation indicator light circuit 2 is connected in series by resistance R 2 and energy-saving indicating lamp L2 and forms as mentioned above.
Aforesaid circuit arrangement also includes the fuse F that is serially connected on the power circuit, prevents the generation of overcurrent or electric leakage situation, the safety of holding circuit device.
Aforesaid heater element H adopts heat-generating disc to heat.
What the first pressure switch S1 described in the utility model, the second pressure switch S2 adopted is recoverable pressure-sensitive switch, waits for the disappearance of trigger condition after it triggers and again closed, forms again path.
Workflow of the present utility model is described below:
When using the utility model pressure cooker to be used for stewing meal or Baoshang, plugged, power supply indicator L1 is bright, by timer switch K setting or after the selected corresponding working time, electric current forms the loop through the protection contact of temperature limit switch T1, protection contact, timer switch K, the second pressure switch S2 and the heater element H of the first pressure switch S1, electric pressure cooking saucepan is started working, and heater element H enters the big fire heated condition, and simultaneously big fire indicator lamp L3 is bright, energy-saving indicating lamp L1 goes out; The pressure that produces when about the water temp. heating to 100 in the electric pressure cooking saucepan ℃ just can make the second pressure switch S2 be triggered, be that electric pressure cooking saucepan pressure of the present utility model is when reaching 50kPa, contact on the second pressure switch S2 disconnects and forms open circuit, force electric current to flow to heater element H by the Current Limiting Diodes D2 in parallel with the second pressure switch S2, and under the effect of Current Limiting Diodes D2, reduced the output size of electric current, make heater element H continue heating at very little power, not only kept the pressure of electric pressure cooking saucepan but also reach energy saving heating purpose.Big fire indicator lamp L3 extinguishes in this moment power supply indicator, energy-saving indicating lamp L2 is bright.After timer switch K timing arrived, timer switch K disconnected, and heater element H quits work, and energy-saving indicating lamp L2 extinguishes, energy-saving indicating lamp L1 is bright.
For the veryer long time of this needs of Baoshang, because the second pressure switch S2 disconnects rear under the effect of Current Limiting Diodes D2, reduced the output size of electric current, make heater element H continue heating at very little power, can not steam in a large number in the cooking process, Baoshang can not overflow, and fully keeps food nutrition, genuineness.
And work as because occurring overtemperature in certain reason electric pressure cooking saucepan course of work, be that temperature is when reaching 165 ℃ that the utility model arranges, the temperature limit switch T1 of anti-high temperature is triggered and is automatically cut off current supply circuit, make power circuit be in open-circuit condition, make heater element H stopped heating, effective like this effect that reaches anti-high temperature is avoided dangerous generation.
And when the malfunctioning or long-time heating of temperature limit switch T1; make electric pressure cooking saucepan pressure excessive after pressure reaches 80kPa the time, the first pressure switch S1 is triggered and is disconnected, and heater element H is quit work; realized double power-off protection, to reach the purpose of anti-high temperature, high pressure.
The setting of each component parameter is just in order to allow the people that this circuit arrangement is better understood in the above specific embodiment; it is as to the restriction of the utility model protection domain, and those skilled in the art can specifically set according to the capacity of the electric pressure cooking saucepan of actual design etc.What the utility model was protected is a kind of electric pressure cooking saucepan pressure sensitive energy saving control circuit device of controlling power output by pressure-sensitive switch and Current Limiting Diodes; purpose that again may energy saving when realizing fast cooking; and do not need often a large amount of pressure releases during electric pressure cooking saucepan of the present utility model work, can not cause a large amount of losses of nutrition.All electric pressure cooking saucepan products of being manufactured out by the technical program or technology enlightenment all should be shown and fall into protection domain of the present utility model.
