Abstract

The utility model relates to a thermal insulation adjustable automatic pressure cooker which is an electrothermal cooking utensil. The utility model is mainly characterized in that the utility model is provided with a pressure sensor and a signal control relay box. An electric contact manometer is used as the sensor, and the pressure in the cooker is transformed into an electric signal. A small electromagnetic relay and a control switch are used for automatic control. After a plug socket is connected well, the automatic control can be carried out by closing the control switch. The adjustable pressure in the thermal insulation multifunction adjustable automatic pressure cooker is controlled in one kilogram per square centimetre, and the utility model can automatically control the pressure.

Description

Thermal insulation adjustable automatic pressure cooker

The utility model belongs to a kind of electric-heating cooking utensil.Be applicable to steaming, boil, stew, fry in shallow oil, low-temperature pressure culinary art and automatic negative-pressure are fresh-keeping etc., especially steam, boil, stew, the time be not by steam discharge restriction pot inner pressure, and be to control the novel pressure cooker that the electric hot tray heating temp is just controlled pot inner pressure with signal control circuit.And can and electric cooker comprehensively be one, pot inner pressure in one kilogram every square centimeter arbitrarily the adjusting.

Present existing pressure cooker, function singleness, automaticity is low, and power consumption is big, and pot inner pressure can not be regulated, and pot inner pressure is controlled by discharged steam, does not have the low temperature heat insulation function.Can not comprehensively be one with electric cooker.

The purpose of this utility model is for a kind of automaticity height that has is provided, power consumption economizes, the function of existing pressure cooker, the effect of electric cooker is arranged again, pot inner pressure is adjustable arbitrarily, and to be the depended on pressure sensor pot inner pressure change to draw is the signal of telecommunication, controls the novel pressure cooker of the adjustable pressure of pot inner pressure by the height of control relay box control electric hot tray heating temp.

The purpose of this heat preserving type is adjustable automatic pressure pot is achieved in that on pressure cooker cover makes the pot inner pressure sensor with an electro connecting pressure gauge, the pressure in the pot is changeed to draw be the signal of telecommunication, and the pressure in one kilogram every square centimeter in any adjustable pot.Join a signal control relay box in addition.The signal of telecommunication of sensor output is by skewer head CT ₂Deliver to signal control relay box CZ ₁The skewer seat, the temperature of being sent by relay box controlled pressure pot electric hot tray just realizes the surplus pressure requirement of setting up earlier of control automatically.

Further retouch reality below in conjunction with implementing accompanying drawing;

Fig. 1 is half cut-away view of the adjustable automatic pressure pot of heat preserving type.

This heat preserving type is adjustable automatic pressure pot as shown in Figure 1, it by pot pin 1, control power supply skewer pin 2, power supply skewer pin 3, magnetic steel temperature limiter button 4, power supply indicator 5, outer pan body 6, inner pan body 7, O-ring seal 8, pot cover 9, pressure sensor (electro connecting pressure gauge) 10, insurance cut down 11, decompression handle 12, inner pan body and pot cover handle 13, outer pan body handle 14, magnetic steel temperature limiter 15, electric hot tray 16, bimetal leaf overheat controller 17, bimetal leaf low temperature warmer 18, drain pan 19 etc. form.

Fig. 2 is the cut-away view of the adjustable automatic pressure pot of insulating type multifunctional signal control relay box.

The pressure signal control relay box of this heat preserving type is adjustable automatic pressure pot as shown in Figure 2, (1) output control power line hole among Fig. 2.(2) input power cord hole.(3) automatic switch.(4) signal input skewer seat.(5) power supply indicator.(67.) control relay.(8) control signal switch.

Fig. 3 is the adjustable automatic pressure pot of a heat preserving type automatic control circuit schematic diagram among Fig. 1 Fig. 2.Be the circuit theory diagrams of Fig. 2 control relay box in the frame of broken lines wherein.

The circuit theory of the utility model pressure cooker as shown in Figure 3; CT ₁Power supply skewer head, CT ₂Pressure sensor output skewer head, CT ₃Power supply control skewer head, CZ ₁Signal control relay input skewer seat, CZ ₂Power supply control skewer seat, K ₁Magnetic steel temperature limiter switch, K ₂Bimetal leaf low temperature warmer switch, K ₃Bimetal leaf overtemperture control switch, K ₄Signal-controlled switch, R ₁Electric hot tray, R ₂R ₃Indicator lamp current-limiting resistance, ZS ₁Power supply indicator, ZS ₂Control signal indicator lamp, J ₁, J ₂Signal control relay, J _1-1, J _1-2, J _1-3, be J ₁The normally opened contact of relay, J _2-1Be J ₂The normally-closed contact of relay.

220 volts of power supplys are by tripod skewer head CT ₁By four pin skewer head CT ₃With four pin skewer seat CZ ₂Through magnetic steel temperature limiter K ₁To electric hot tray R ₁The back is by bimetal leaf overheat controller K ₃Become the loop.Power supply indicator CS ₁With current-limiting resistance R ₁Whether be connected in parallel on the electric hot tray two ends behind the polyphone makes it indicate electric hot tray to work.By automatic switch ZK, four pin skewer head CT ₃With tripod skewer head CT ₂, skewer seat CZ ₁220 volts of power supply supply pressure sensor JY, pressure sensor ZY makes sensor with every square centimeter of electro connecting pressure gauge below 5 kilograms, it has high pressure normally opened contact and low pressure normally-closed contact, changes according to pot inner pressure and draws that it is often opened, normally-closed contact is exported control signal.Signaling switch K ₄Control JTX series Small Universal electromagnetic relay J ₁Adhesive is because of relay J ₁Adhesive, J _1-1, J _1-2, J _1-3The contact becomes normally closedly by often opening, and makes J ₁Self-locking, J ₂Perform the preparation of adhesive, simultaneously J _1-2Contact and low temperature warmer, magnetic steel temperature limiter is in parallel to be connected, thus control electric hot tray R ₁Work, signal lamp ZS ₂With current-limiting resistance R ₃Be connected in parallel on relay J after the series connection ₁Two ends are done the control indication and are used.When the pressure cooker internal pressure because electric hot tray R ₁Constantly heating, thus kettle temperature rising pressure is also increased, and when pot inner pressure was elevated to the maximum pressure of surplus setting earlier, because the effect of pressure sensor JY makes the high pressure normally opened contact become normally-closed contact, the output signal of telecommunication made relay J ₂Adhesive is simultaneously because J _2-1Normally-closed contact is along with J ₂J is opened, made to adhesive by normally closed often becoming ₁Relay system is put, electric hot tray R ₁Quit work.Become repeatedly by pressure sensor JY and to draw output signal control relay J ₁J ₂Realize automatic control.

Making presser sensor device and relay with electro connecting pressure gauge comes the controlled pressure pot to realize automation. Unique properties, purposes is various, automation degree height, good energy-conserving effect, this pot becomes the pressure cooking appliance series of products with abnormity, and the use function of independent electric cooker is arranged.
