A kind of electric cooker micropressure spill-proof steam valve
The present invention relates to a kind of electric cooker steam valve, be specifically related to a kind of steam valve of controlling vapour pressure in electric cooker and preventing overflow.
Electric cooker is to utilize electric energy to change the cooker of interior energy into, and easy to use, sanitation and hygiene, also have multiple operating functions such as food steam, boils, stewes, has now become daily household electrical appliance.The invention of electric cooker has reduced a lot of families and has spent in the time of cooking.Pot of electric cooker covers to set up steam (vapor) outlet, and while cooking, when pressure reaches after certain value, part steam is discharged from steam (vapor) outlet, ensures the security using.The setting of steam (vapor) outlet, should ensure the smooth discharge of steam, keeps again the pressure of electric cooker, and the interior liquid that simultaneously also will prevent from stewing overflows from steam port with steam.
The electric cooker of selling or using in the market, has many rice cookers to lay claim to minute-pressure, and have anti-overflow effect, but actual conditions has two kinds: one be observed pressure all below 0.1KPa, almost there is no pressure; Really can realize minute-pressure effect although another kind of, the anti-overflow effect after producing pressure is undesirable, and backflow effect is difficult to realize.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of electric cooker steam valve that can effectively realize minute-pressure effect and prevent simultaneously overflow.
For addressing the above problem, the invention provides a kind of electric cooker micropressure spill-proof steam valve, be arranged at the steam outlet place of electric cooker cover, comprise steam cover, valve gap, valve gap seat, valve body, valve gap and valve gap seat are linked into a whole, and valve body is positioned at valve gap below, in valve gap, there is valve gap chamber, in valve body, have exhaust chamber, valve body below has steam inlet, and steam cover top has steam exhaust-gas mouth; It is characterized in that described steam cover is positioned at valve cover cavity indoor, in valve body, have a pressure regulation body to be connected with steam cover, change and do axially reciprocating in valve gap chamber and exhaust chamber with the steam at electric cooker steam outlet place.
The beneficial effects of the utility model are: the utility model is simple in structure, comprise steam cover, valve gap, valve gap seat, valve body, in valve gap, there is valve gap chamber, in valve body, there is exhaust chamber, it is indoor that steam cover is positioned at valve cover cavity, has a pressure regulation body to be connected with steam cover, in valve body in the time that electric cooker internal pressure increases, pressure regulation body, together with the steam cover exhaust steam that rises, stops that bulky grain thing and liquid enter steam exhaust-gas mouth simultaneously; When in electric cooker during without pressure, steam cover and pressure regulation body are returned to original position according to self gravitation.Can effectively control pot internal pressure between 0-5KPa, discharge in time steam in pot, realize liquid backflow simultaneously.

Detailed description of the invention
Shown in accompanying drawing 1-4, a kind of electric cooker micropressure spill-proof steam valve, is arranged at the steam outlet place that pot covers, and comprises steam cover 1, pressure regulation body 2, valve gap 3, valve gap seat 4, valve body 5, pressure spring 6, one-way sealing seal 7, sealing ring 8.Valve gap 3, valve gap seat 4 are integral by ultrasonic bonding, and center is valve gap chamber 4A, the 5A of below valve body Nei You exhaust chamber; Steam cover 1 links into an integrated entity by buckle 2A with pressure regulation body 2, disassembling cleaning.Pressure spring 6 is fixed between valve gap seat 4 and pressure regulation body 2, acts on and being in the time having minute-pressure, and pressure spring 6 compresses, and steam cover 1 and pressure regulation body 2 rise, and during without minute-pressure, pressure spring 6 resets, and drives steam cover 1, pressure regulation body 2 to return to original position; Pressure regulation body 2 shapes are made as rotary body, can stop that bulky grain object enters steam vent, is back in pot; Steam cover 1 top is provided with steam exhaust-gas hole 1D, and border, hole is provided with encloses muscle, and when in pot during without minute-pressure, steam exhaust-gas hole 1D contacts closure with valve gap seat 4.In the time having minute-pressure in pot, steam cover 1 and pressure regulation cap 2 rise, and steam can be emitted from steam exhaust-gas hole 1D; Valve gap seat 4 tops are provided with exhaust passage 4C, and on passage, square opening border is provided with and encloses muscle, and when in pot during without minute-pressure, exhaust passage 4C contacts with steam cover 1; While having minute-pressure, steam cover 1 and pressure regulation body 2 rise, and exhaust passage 4C opens; The keep to the side below of edge of valve gap seat 4 is provided with little return port 4B; Valve body 5 is positioned at valve gap 3 belows, has the 5A of exhaust chamber valve body 5 bottoms and is provided with large return port 5C, and one-way sealing rubber cushion 7 is equipped with at return port place, can prevent that the steam in pot from entering discharge chamber 5A from large return port 5C, but allows the hydrops of discharge chamber 5A to be back in pot; Valve gap 3 is connected by buckle with valve body 5, between sealing ring 8 is housed, interior minute-pressure steam leakage prevents from stewing.
When electric cooker work, along with temperature rise in pot, when pot internal pressure rises; steam and grain of rice mixture enter air induction mast 1B and the 5A of exhaust chamber by steam inlet hole 7A; when pressure reaches certain value, steam cover 1 is with pressure regulation body 2 axially toward rising, and steam exhaust-gas mouth 1D opens.Discharge pot internal pressure simultaneously.A grain of rice liquid mixture part is stopped and is back in pot by valve gap seat 4.Another part enters the 5A of exhaust chamber and is rotated pressure regulation body 2 to be blocked in return port 5C upper, and grain of rice liquid mixture accumulates gradually, in the time that gravity reaches certain value, presses off one-way sealing foot pad 7, is back in pot by large return port 5C.The steam that enters the 5A of exhaust chamber enters valve gap chamber 4A by steam channel 4C, effect is to promote pressure regulation cap and axially rises, steam is discharged from steam vent 1D, do not have the steam condensation of discharging to become liquid to be back to the 5A of exhaust chamber from little return port 4B, then be back in pot.After pot internal pressure declines, steam cover 1 resets to original position with pressure regulation body 2 under the effect of self gravitation and pressure spring 6, blocks exhaust passage 4C and steam vent 1D.Repeat above process, steam valve had both been realized the discharge of steam, had realized again the backflow of liquid simultaneously, and the internal pressure that makes to stew maintains in 0.1-5KPa dynamic range.
Further, pressure regulation body 2 is detachable with steam cover 1 buckle position, and sealing ring 8, one-way sealing rubber cushion 7, pressure spring 6 are all detachable, facilitate consumer to clean.
Further, can regulate reset speed and pressure size with shape, the weight of pressure regulation body 2 by adjusting steam cover 1.
The above; only for the better detailed description of the invention of the present invention, but protection domain of the present invention is not limited to this, is anyly familiar with in technical scope that those skilled in the art disclose in the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore protection domain of the present invention is as the criterion with the protection domain of claims.
