Description

Full automatic gas burning pressure cooker

The utility model relates to a kind of practical cooking apparatus--pressure cooker, and particularly relevant is the pressure cooker of thermal source with the fuel gas.

Common pressure cooker directly places on the cooking stove during use, and cooking process is manually controlled by the operator.Generally speaking, when being heated to internal pressure with pressure cooker, combustion gas reaches when limiting pressure, at this moment only the heat of need original 1/3～1/2 just can keep the pot inner pressure weighing apparatus fixed, so just need manually gas quantity to be reduced, thereafter rule of thumb, think reach certain hour after, food is cooked, needs again with manually combustion gas being turned off.If operator's inadvertent general idea is gently then wasted combustion gas, heavy then can cause danger, so inconvenience is arranged when using.At present, the electric heating Automatic pressure cooker of selling on the market, as Chinese patent 87200881.9 described electric automatic pressure pots, though realized the Automatic Control of cooking process, but owing to use electric energy, so the area of certain limitation, especially shortage of electric power is arranged when using as the heating thermal source, influenced by power supply, can't use during power failure.In addition because electricity charge costliness often makes family's electricity charge spending be unequal to bearing and reducing and use.

The purpose of this utility model is to avoid above-mentioned deficiency of the prior art, and providing a kind of is the Automatic Control pressure cooker of thermal source with the combustion gas.

The purpose of this utility model realizes by following measure:

The utility model is made up of pressure cooker body, gas combustion apparatus and control device three parts, and wherein, pressure cooker body is identical with the usual pressure pot, and is the branch body structure with shell and burner, can take out in shell when containing food.Burner is made up of burner and igniter.Burner can select to use single burner, also can be to be the main burner of concentric circles and the burner that auxilliary burner constitutes, i.e. twin furnace head by two.Igniter can select to use piezoelectric ceramic ignitor, also can select electronic impulse ignition apparatus for use.Control device is a key component of the present utility model, is to be used for realizing pressure cooker cooking process Automatic Control, replaces manually to keep an eye on and manually control.Control device described in the utility model partly is organically combined by temperature detector, rod gear, distributing valve and timer etc. and constitutes.During work, beginning is with big fire (or double-head) Fast Heating, when pot inner pressure reaches or when limiting pressure (for example 60KP), temperature detector records temperature this moment, by lever transmission, signal is passed to distributing valve, distributing valve closed portion air inflow, make it to transfer to automatically little fire (or single flame head) heating, start the timer timing simultaneously, the pressure that at this moment can keep qualification in the pot is constant, uses complete when the predefined time, the timer action, by leverage, close distributing valve, another part air inflow is closed, extinguish whole duration and degree of heatings, culinary art finishes.

The utility model is described in further detail below in conjunction with accompanying drawing embodiment.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the schematic diagram of mechanical timer control in the control device described in the utility model.

Shown in figure one, pressure cooker body is made up of pot courage＜11 〉, pot cover＜12 〉, limit peace valve＜13 〉, safety valve＜14 〉, handle＜15 〉, is the branch body structure with shell＜10 〉.Burner is made of main burner＜21〉and auxilliary burner＜22 〉, air inlet pipe＜23 〉, also can be made of single burner.The piezoelectric ceramic ignitor that the igniter selection is made up of spark mouth＜25 〉, spark lead-in wire＜26〉and piezoelectric ceramics＜27 〉, piezoelectric ceramics one end has a pull bar＜28〉that is hinged with lever＜41 〉,＜43〉push button, to spur pull bar＜28 〉, piezoelectric ceramic ignitor is started, produce spark, the combustion gas of igniting between spark mouth＜25〉and burner＜21 〉,＜22 〉.

Temperature detector is selected the magnet steel temperature detector for use, is combined by magnet steel＜31 〉, permanent magnet＜32 〉, inner spring＜33 〉, outer spring＜34 〉, push rod＜35 〉, and push rod＜35〉upper end joins with permanent magnet＜32 〉, lower end and lever＜41〉terminal hinged.＜43〉push button, effect by lever＜41〉and push rod＜35 〉, can make permanent magnet＜32〉and magnet steel＜31〉adhesive, limit pressure when pot inner pressure reaches, when temperature reaches certain value, magnet steel＜31〉takes off magnetic, under the effect of gravity and inner spring＜33 〉, permanent magnet＜32〉comes off, and its action is delivered on the lever＜41〉by push rod＜35 〉.

Distributing valve＜51〉has an air inlet, two gas outlets, there are two pin control valves inside, form by needle＜53 〉,＜35〉and spring＜54 〉,＜56 〉, wherein, needle＜53 〉,＜55〉lower end contact with lever＜41 〉,＜42〉front end position respectively, and the upper end is equipped with spring＜54 〉,＜56〉respectively.Needle can lead to combustion gas during by lever jack-up; When lever external force was eliminated, under the effect of upper end spring, needle rebounded in the passage, can close combustion gas.Outside the air inlet of distributing valve＜51 〉, a stepless knob air valve＜50〉also can be installed, be used to control the big or little of air inflow.

As depicted in figs. 1 and 2, timer is a mechanical timer, and a brake bar＜61 〉, push rod＜62 〉, pinion＜63 〉, the recessed wheel＜62〉are arranged on it.The lower end of brake bar＜61〉is corresponding with lever＜41〉rear end, and when pushing button＜43 〉, brake bar＜61〉separates with lever＜41 〉, under the gravity effect, brake bar＜61〉falls, and an eedles is arranged on it, block pinion＜63 〉, make timer be in on-position.When lever＜41〉when upspringing, jack-up brake bar＜61 〉, braking is eliminated, and timer can timing.The recessed wheel＜64〉fixedlyed connected with timer knob＜60 〉, when turn knob＜60 〉, can make push rod＜62〉depress the rear end of lever＜42 〉.Timing finishes, and push rod＜62〉upper end is pressed into the recessed recess of taking turns, and lever＜42〉resets.

Lever＜41 〉,＜42〉are the maincenter parts of The whole control device, be installed on the same fulcrum＜40 〉, igniter, temperature detector, distributing valve, timer are organically combined by lever principle, interacted, finish the required various mechanical actions of cooking process control.

The course of work of the present utility model is as follows:

The first, push button＜43 〉,, can finish following action by the effect of lever＜41 〉, the one, jack-up needle＜53〉makes combustion gas enter main burner＜21 〉, and the 2nd, start piezoelectric ceramic ignitor, light a fire, light main burner＜21 〉; The 3rd, make the brake bar＜61〉of timer fall brake timer.

The second, twisting timer knob＜60 〉, at this moment setting-up time acts on lever＜42〉rear end by push rod＜62 〉, makes it jack-up needle＜55 〉, makes combustion gas enter auxilliary burner＜22 〉, and the main burner flame that is being burnt ignites.

More than two steps realize the big fire Fast Heating, make the pressure cooker internal pressure reach qualification pressure as early as possible.

Three, when reaching qualification pressure, magnet steel＜31〉takes off magnetic, promotes lever＜41 〉, and permanent magnet＜32〉and push rod＜35〉come off, button＜43〉is rebounded, at this moment needle＜53〉passage that rebounds is closed main burner, simultaneously lever＜41〉rear end jack-up brake bar＜61 〉, start timer, pick up counting, auxilliary burner burns away, to keep pot inner pressure.

Four, timing finishes, and push rod＜62〉upper end is pushed back the recessed recess of taking turns, needle＜55〉passage that rebounds, and close auxilliary burner, culinary art finishes.

If select single burner for use, said process is constant, can realize Automatic Control equally.

The utility model has compared with prior art realized having the advantages such as energy-conservation, safe, easy to use with the pressure cooker cooking process Automatic Control of combustion gas as thermal source. Compare with electric pressure cooking saucepan, have advantage, especially power shortage area that use is not powered and limited, this advantage is more outstanding.
