Description

Food low pressure pot

Technical field: the utility model relates to a kind of low pressure pot, particularly a kind of food low pressure pot belongs to the cooker technical field.

Background technology: people constantly improve and design novel diet product heater in order to improve the quality of living.Common pressure cooker has that food is easily well-done, energy-conservation, the timesaving advantage, is particularly suitable for the needs of highlands use.But, because of pot inner pressure designs at 80KPa, the interior maximum temperature of pot can reach about 113 degrees centigrade during use, so the selection of material requires height when making, materials are many, need as the pressure cooker of 24cm (7L) specification with aluminium material 1.75kg, and, the pressure cooker structure is comparatively complicated, and its pressure limiting valve adopts spring controlled form, easily breaks down after working long hours.Will could open pot cover after cooling during use, inconvenience uses misoperation easily to lead to a disaster.At present, domestic pressure cooker, all more than 50KPa, can accurately be controlled at the following cooker of 20KPa does not also have operating pressure.Recently, fast enamelware pot has appearred on the market, its advantage is to block pot cover by handle, make the pot cover folding with convenience, add pine for also can be safely folding pot cover at any time, be provided with sealing ring in the pot cover, offer an aperture on the pot cover, under the effect of thermal source,, can produce certain pressure in the pot when the vapor volume that takes place in the pot during greater than the aperture capacity.This product materials being fabricated is saved more than pressure cooker, and coefficient height safe in utilization, its weak point is: can not accurately control the pot inner pressure situation, because of having adopted the spring bearer plate formula, handle compresses intensity difference, so pot inner pressure has rising slightly, steam is just escaped to overflow from the pot cover edge, and energy-saving effect is poor, is difficult to the special requirement of competent highlands to the cooker performance.

Summary of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art, a kind of food low pressure pot is provided, by control to steam pressure, food is hotted plate under the inferior hot states of 100 degree-103 degree, reach easy to use, safe, easily boil, energy-conservation, timesaving effect.The utility model mainly comprises: pot body, lower handle, upper handle, sealing ring, pressure-relief valve, silica gel plug, relief hole, pot drip guard shield, pressure limiting valve, pot cover, its connected mode is: lower handle is connected with the pot body, upper handle is connected with lower handle by screw, the pot cover circumferential edge is along being provided with a ring recess, the edge of pot cover embeds the recess of sealing ring, following " L " type groove with pot body bead of sealing ring is connected, pressure limiting valve, pressure-relief valve, pot drip guard shield and are arranged on the pot cover, pot drips the cooker cover portion that guard shield covered and is arranged with relief hole, and silica gel plug is arranged at the relief hole place.

Pressure limiting valve mainly comprises: steel ball, air admission hole, steam vent, air admission hole, steam vent is located at limiting valve body, steel ball is located in the pressure limiting valve pocket, pressure-relief valve mainly comprises: press rods, unload gas port, air inlet, press rods is located within the release valve body, the release valve body is stretched out in the upper end of press rods, the pressure-relief valve housing is offered and is unloaded gas port, air inlet, air admission hole, air inlet is arranged in the pot cover, steam vent, unloading gas port is arranged at outside the pot cover, pot drips guard shield and is provided with the gas outlet, pot drips in the guard shield cavity, in a single day silica gel plug runs into and is stored in a pot guard shield internal cavity after superpressure breaks away from relief hole, and a large amount of compressed gas can waltz through relief hole and gas outlet, make pot inner pressure reach normal rapidly.

During use, upper handle is connected with lower handle by screw, form the handle locking device, upper handle is that 90 degree rotations can be done in the axle center with the screw, make the pot cover folding with convenience, when upper handle became cross with lower handle, an end of upper handle compressed pot cover, being arranged at pot cover makes a pot cover and a pot figure become one in conjunction with tight, sealing effect better seal body with the sealing ring of pot between the body.The pot heat of experiencing, pot inner pressure constantly rises, when pressure surpasses 10KPa, gas in the pot is by the air admission hole of pressure limiting valve, the jack-up steel ball, discharge from exhaust outlet, at this moment, regulating thermal source can remain on pot body internal pressure below the 8KPa, when the pressure limiting valve exhaust too late, when causing pot inner pressure to be elevated to 10KPa, press rods in the pot in the gas jack-up pressure-relief valve, air inlet by pressure-relief valve, automatically discharge gas in the pot to unloading gas port, the pressure-relief valve press rods that rise this moment is represented reduce the thermal source supply, save the energy, when pot inner pressure returns to 10KPa when following, pressure-relief valve stops exhaust automatically, and the press rods of pressure-relief valve sets back, when continuation raises and reaches 20KPa-40KPa as the pot internal gas pressure, the silica gel plug that is covered in relief hole will be pushed out, and the gas in the pot releases rapidly through the gas outlet by relief hole, thereby discharge whole pressed gas in the pot, pot drips in the guard shield cavity, and in a single day silica gel plug runs into and be stored in a pot guard shield internal cavity after superpressure breaks away from relief hole, and over-pressure gas can waltz through relief hole and gas outlet.The pressure limiting valve of food low pressure pot, pressure-relief valve adopt GRAVITY CONTROL, and numerical value is accurate, reliable in action, utilizes silica gel sheet elastic reaction, and pressure release is in time guaranteed safe and reliable under improper situation.

The utility model is by the multistage accurate control of pressure limiting valve, pressure-relief valve and silica gel plug pressure release, make and keep the certain pressure value in the pot, cooking food easily boils, the while nutritional labeling is destroyed few, keeps genuine, and situation is hotted plate in folding pot cover observation at any time during work, in time add materials, condiment, easy to operate, maximum temperature is about about 103 degrees centigrade in the pot, greatly improves the security reliability of using.Owing under sealing state, heat, than conventional cooker can save energy, 30-40% when saving, the air pressure low low-boiling problem of heating up water, cook in highlands can be solved.Compare with the pressure cooker of making same specification, can save more than 40% of aluminium material consumption.
