Abstract
The utility model relates to a pressure self-control pressure cooker. The upper part of a cooker body (3) is provided with holes. The mouth opening end of a corrugated tube (4) is communicated with the inner cavity of the pressure cooker by using a connector (5). The other end of the corrugated tube (4) is used for driving a heater switch (1). The heating quantity of the heater exerting on the pressure cooker can be adjusted by using the change of the mechanical displacement of the corrugated tube following the change of the pressure in the pressure cooker. Thus the working pressure of the pressure cooker can be accurately controlled. The pressure cooker can be used for cooking delicious and soft rice; no overflow occurs at the time of gruel cooking; no clogging at the time of bean or peanut boiling; the bone is crisp and the meat is ripe at the time of meat cooking.
Description
A kind of pneumatic self-controlled formula pressure cooker belongs to cooking utensils, and it is suitable for cooking, cooks gruel, Canton style roast pork and sterilization.
Existing pressure cooker can not be controlled automatically to the heat that adds of heater, and it is discharged the hot gas that exceeds operating pressure outside the pot by the blast pipe of pressure limiting valve.So not only waste energy, and cooking gruel, may cause an explosion accident because of stopping up blast pipe when boiling beans.
The utility model is to adopt an easy device, utilizes the air pressure in the pressure cooker, and control heater is realized pneumatic self-controlled purpose to the heat that adds of pressure cooker.
Major scheme of the present utility model is: open 1-3 hole on the pot body of pressure cooker, with connector the inner chamber of the openend of bellows and pressure cooker is communicated with, like this, the displacement of the bellows other end is followed the variation of pot inner pressure fully and is changed.Utilize this mechanical displacement of following, drive heater button and regulate the add heat of heater, the pressure in the pressure cooker is automatically maintained in the design load scope all the time pressure cooker.
The utility model is simple in structure, precise control, and the Shi Buhui that cooks congee boils excessive, and perfume (or spice) is soft when cooking, and can not stop up when boiling beans or peanut, keeps genuine during cooking meat, soft bone and mashed meat.
Accompanying drawing 1 is the agent structure schematic diagram of broken section of the present utility model.
Accompanying drawing 2 is structural representations of broken section of the present utility model.
Accompanying drawing 3 is modular construction schematic diagrames of a kind of connector of the present utility model.
Accompanying drawing 4 is structural representations of the broken section of another program of the present utility model.
Accompanying drawing 5 is schematic diagrames of a kind of existing pressure cooker.
Now embodiment of the present utility model is described in detail in detail with embodiment:
Embodiment 1: " pneumatic self-controlled formula pressure cooker " as shown in Figure 1, it is made of pot body [3], pot cover [7], safety valve [9], sealing ring [8], hole [6], connector [5], bellows [4].Wherein, use "
" connector [5] that the hollow pipe of shape is made, between the inner chamber of the openend of bellows [4] and pressure cooker, [6] are its connection through the hole.After heater [2] heating, bellows [4] extends downwards because of pot inner pressure rises, when pot inner pressure reaches design load, the lower end of bellows [4] cuts off heater button [1], and at this moment, heater [2] cools off naturally, pot inner pressure descends, bellows [4] also bounces back, and heater button [1] is and then connected, and heater [2] begins heating again.Obviously, and so forth, controlled the operating pressure in the pressure cooker effectively.
Above-described heater button [1] can adopt the electrical contact switch of snap-type, directly controls the on off operating mode of electric hot tray power supply, reaches the purpose that control adds heat.Also can adopt other electric switch to control magnetic valve, reach the purpose that control adds heat by the solenoid control liquefied gas again.Can certainly adopt the stroke valve to control the add heat of liquefied gas to pressure cooker.
Embodiment 2: the connector in the foregoing description 1 [5], can be as shown in Figure 2, and by Connection Block [5A] and connecting plate [5B] compound composition.And in connecting plate [5B] (referring to accompanying drawing 3), punching press is made groove [15], supporting plate [13] and backplate [16] and with behind groove [15] mating holes [6], with aluminium rivet it is riveted on pot body [3].In addition, at the upper end of bellows [4] welding screwed pipe [10], welding spiral shell valve [11] in lower end screws (sealing) to screwed pipe [10] on connector [5A].Load onto drive link [14] in the screw of spiral shell valve [11], overlap upper spring [12], and it is shelved on the supporting plate [13], other structure is identical with embodiment 1.
Embodiment 3: as shown in Figure 4, open a hole [17] on pot cover [7], what made by high-temperature resistant rubber, the outer round recessed of all reeded sealing ring connector of its inside and outside wall [20] is inserted in the hole [17].Openend at bellows [18] welds " ⊥ " shape hollow circular-tube [19], and it is inserted in the inboard wall groove of connector [20].The other end of bellows [18] is by connecting rod [21], and the transmission mechanism of connecting rod [22] and connecting rod [23] drives heater button [1], and other structure is identical with embodiment 1.
The utility model adopts the air pressure in the pressure cooker to carry out automatic control, and it both can control electric hot tray, also can control gas range.The not exhaust in the process owing to boil, therefore not only energy-conservation, the more important thing is not exist because of obstruction to cause an explosion accident.Use it safe and reliable.
