Abstract
The invention provides an electric pressure cooker using insulation board, which comprises a cooker body, an inside pot, a cover, a base and an electric hot tray, wherein the inside pot is arranged in the cooker body; the cover is arranged above the cooker body; the electric hot tray is arranged in the base; insulation boards are arranged on the electric hot tray and in series connection with a heating control circuit; and the insulation boards, a timer motor, a pressure switch and a temperature limiting switch are parallelly connected in the heating control circuit. The electric pressure cooker using insulation board has the advantages of simple structure, easy manufacturing and convenient installation and operation; moreover, because the low-power heating insulation board is adopted, the materials are saved and the service life of the pressure cooker is prolonged.
Description
Technical field
The present invention relates to the electric pressure cooking saucepan technical field, more specifically to the improvement of electric pressure cooking saucepan temperature control technology.
Background technology
At present, disclosed electric pressure cooking saucepan is various in style on the market, and style is also of all kinds, but the insulation of existing electric pressure cooking saucepan all adopts the power on/off of insulation switch, control circuit to realize.Chinese patent " a kind of electric pressure cooking saucepan preservation and controlling circuit ", the patent No.: 200920055077.3, a kind of electric pressure cooking saucepan preservation and controlling circuit is provided, has comprised single-chip microcomputer, temperature measurement circuit and heating control circuit, the output of described temperature measurement circuit is connected with the single-chip microcomputer input; Described single-chip microcomputer output is connected with the input of heating control circuit, and described single-chip microcomputer comprises the temperature judgement comparison module of the temperature level control heating control circuit heating that records according to temperature measurement circuit.Temperature judges that comparison module during less than setting value, can make the heating of MCU driving heating control circuit at kettle temperature, can guarantee automatically that kettle temperature remains on a stationary temperature value, helps interior the food of pot and is incubated, assurance food taste.But prior art internal wiring complexity, the maintenance probability big, insulation switch and connection line are many, overall cost height, and in the electric pressure cooking saucepan course of work, the control temperature of insulation switch is in off position all the time at the 65-85 degree, and the pressure kettle temperature descends very fast, cause pressure switch work frequent, influence its life-span.On the other hand, connect an electric hot tray all with heating with full power, the loss of the energy that causes so also strengthens.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiency of prior art and electric pressure cooking saucepan that a kind of simple in structure, easy to manufacture, cost and the use warming plate that energy consumption is low, the life-span is long are provided.
The present invention can take following technical measures to solve:
A kind of electric pressure cooking saucepan that uses warming plate, contain a pot body, interior pot, pot cover, base, electric hot tray, interior pot places in pot body, pot cover is installed on the top of pot body, electric hot tray is installed in the base, its structural feature is: warming plate is installed on electric hot tray, and warming plate is to be connected in the heating control circuit of electric hot tray, and is connected in parallel in the heating control circuit with timer motor and timer switch, pressure switch and temperature limit switch.
The power of above-mentioned warming plate is 30W-75W.
The shape of above-mentioned warming plate is any in square, circular, crescent, the triangle.
Above-mentioned warming plate 6 is 1-4, and is in parallel each other or be connected in the circuit, is square on electric hot tray or triangle is installed.
Above-mentioned warming plate 6 is installed on the boss 15 of electric hot tray 5 belows setting.
Outstanding effect of the present invention is:
1), the present invention simple in structure, easy to manufacture, install and use easy.
2), the present invention is directly installed on warming plate on the electric hot tray, to guarantee the abundant transmission of heat.
3), cost of the present invention is low, uses small-power heat tracing plate, saved consumptive material and shortened heat time heating time of pressure cooker.
Below in conjunction with accompanying drawing the present invention is done detailed explanation:
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is an entity wiring diagram of the present invention.
Fig. 3 is an operation principle block diagram of the present invention.
The specific embodiment
A kind of electric pressure cooking saucepan that uses warming plate as Fig. 1, Fig. 2 and shown in Figure 3, contains pot body 1, interior pot 2, pot cover 3, base 4, electric hot tray 5, and interior pot 2 places in pot body 1, and pot cover 3 is installed on the top of pot body 1, and electric hot tray 5 is installed in the base 4.Warming plate 6 is installed on electric hot tray 5, and warming plate 6 is to be connected in the heating control circuit of electric hot tray 5, and is connected in parallel in the heating control circuit with timer motor 7 and timer switch 8, pressure switch 9 and temperature limit switch 10.The power of warming plate 6 is 40W.The shape of warming plate 6 is square.Warming plate 6 is installed in the A place.
With embodiment 1.Different is: the power of warming plate 6 is 70W.The shape of warming plate 6 is a crescent.Warming plate 6 is 3, and is in parallel each other or be connected in the circuit, and warming plate 6 is installed on the boss 15 that electric hot tray 5 belows are provided with.Installation triangular in shape on electric hot tray 5.
Operation principle:
When timer switch 8 is in on-state, current direction: the coupler 11 → L → indication 10 of Thermal Cutoffs 12 → timer switch 8 → heat/pressure and electric hot tray 5 → N → coupler 11; Realize small-power heat tracing plate 6.
After pressure switch (13) and one of them disconnection of temperature limit switch (14), coupler (11) → L → Thermal Cutoffs (12) → timer motor (9), → timer switch (8) → heat/pressure indication (10) and electric hot tray (5) → N → coupler (11).
