Abstract

The utility model provides a multi-functional pressure cooker cover as a cooker, which is provided for aiming at the defects of the known pressure cooker that a cover can not be quickly opened, and solid food such as the steamed bread and flapjacks can not be heated after cooking and maintaining pressure. The technical scheme is as follows: the fully spherical crown-shaped surface of the known pressure cooker cover is used as a bottom, a round frame is sleeved on the bottom to be weld-processed into a circular water tank in an osculating way, and a water tank cover is covered on the water tank to form the multi-functional pressure cooker cover; the uncirculated air in the water tank has thermal insulation function, so that the temperature and pressure in the cooker can be quickly boosted, the ohmic heating time in the pressure maintaining process can be reduced, and the holding time can be prolonged; after cooking and maintaining pressure, the water tank cover is taken off, and water is poured in the water tank to cool, so that a float quickly falls off, and then the cover can be opened; the temperature in the cooker is 110 DEG C in the cooking and pressure maintaining process, and the temperature in the water tank (i.e. on the original cooker cover) is about 105 DEG C, and therefore, the solid food can be heated by pouring water in the water tank and putting a grid, and can be heated by hot (infrared) radiation without pouring water.

Description

The multi-functional pressure pot cover

(1) technical field:

Cooking utensils.

(2) background technology:

Pressure cooker, especially electric pressure cooking saucepan provide safely for people's the cooking, save time, energy-conservation facility.But inconvenience is also arranged simultaneously:

1, after cooking pressurize finished to enter keeping warm mode, the pot internal gas pressure still is higher than the outer air pressure of pot can not uncap, and float falls just and can uncap about 20 minutes if natural cooling will wait.Want fast quick-opening lid, just must mention pressure limiting vent valve steam bleeding, but then can not steam bleeding if endure spoon meat (as congee class, viscosity liquid), cover with wet tissue and on pot cover, quicken cooling, generally also in cold water, soak wet tissue and float is fallen open pot cover.

2, with ordinary pan cook gruel, stew can be simultaneously with the solid food of cage Drawer heating steamed bun, pancake and so on, with pressure cooker then can not, also need additional heat may.

(3) summary of the invention:

At the pressure cooker above shortcomings, the utility model proposes a kind of multi-functional pressure pot cover.This multi-functional pressure pot cover has known pressure cooker cover and known float and float-controlled valve, bleeder pipe and pressure limiting vent valve on it.The feature of described multi-functional pressure pot cover is to be the end by the whole ball crown types surface with the known pressure cooker cover that comprises known float and float-controlled valve, bleeder pipe and pressure limiting vent valve, with along the circumference on described whole ball crown types surface and this known pressure cooker cover closely the round metal frame of welding be the circular channels of wall and cover sink cover composition on described tank.The 26S Proteasome Structure and Function that has known pressure cooker cover at the bottom of the tank promptly has known pot cover and known float and float-controlled valve, bleeder pipe and pressure limiting vent valve above it, and the same as with known pressure cooker cover known pressure cooker combination.The round frame on being enclosed within the bottom of the tank and the circular tank of the close welding processing of circumference of bottom, the height of flume wall does not influence the pressure limiting vent valve and is advisable to cover sink cover.Join circular channels lid on the tank, can prevent that as common pot cover steam from overflowing and water spills.Above-mentioned multi-function pressure cooker is stamped three kinds of functions.

1, heat insulation function: cover sink cover, become an airtight space in the tank, wherein immobilising air has heat insulation function, can make and heat up quickly in the pot and boost, and not only can reduce the number of times of energising heating in the pressure maintaining period, also can prolong temperature retention time.

2, quick cooling function: after the cooking dwell time finishes, take away sink cover, add cold water acceleration cooling in tank, float is fallen fast can uncap.

3, heating solid food function: existing known pressure cooker is in cooking pressure maintaining period, and kettle temperature is 110 ℃, and temperature is about 105 ℃ on the pot cover, so can heat solid food in the tank that with former pot cover is the end.Double-edged fine-toothed comb can heat solid food as if adding water and fill up upward in tank, and not adding water can be by heat (infrared ray) radiation heating solid food.

Fig. 4, do not put the multi-functional pressure pot cover of water valve and always scheme: 9, handle; 10, sink cover; 11, ear; 12, sealing ring; 13, vent valve.

(5) specific embodiment:

With known 5 up voltage power pots is example: the whole spherical surface with pressure cooker cover (1) is the bottom surface, curves round frame (2) with a strip metal lath, is welded into a tank (3) closely along circumference and this surface on described spherical surface.Known float on the former known pressure cooker cover (1) and float-controlled valve (4) structure and invariant position; The structure of known bleeder pipe and pressure limiting vent valve (5) is constant, and the position is contained in the central authorities of tank (3) bottom surface (former pressure cooker cover).Cover bleeder pipe and pressure limiting vent valve (5) with a cylindrical shape protective cover (6), extruding bleeder pipe and pressure limiting vent valve (5) influence pressurize and venting when avoiding putting into solid food in tank (3).The leg of cylindrical shape protective cover (6) lower end is away from the bottom surface, so that the air communication mistake, the upper end is lower than bleeder pipe and pressure limiting vent valve (5), and the air-flow of rising is flowed out.Sink cover (10) should and be done more thick and heavyly with glass material, and sealing ring on the peripheral sleeve (12) reduces hot vapour and emerges from sink cover (10) periphery.Adorn a vent valve (13) on the sink cover (10), vent valve (13) cuts out generally speaking, when heating solid food, in tank (3), add entry, open vent valve (13) discharge section hot-air, close vent valve (13) then, to keep the water content of hot vapour in the tank (3), make the solid food of heating soft.Handle (9) is contained in round frame (2) next door of tank.A discharging valve (8) is adorned in the round frame (2) of tank below, if when using water cooling, treat that float falls after, open discharging valve (8) water bled off, can raise the multi-functional pressure pot cover.

As second embodiment, Fig. 4 does not put the multi-functional pressure pot cover of water valve and always schemes, and the difference of it and above-mentioned multi-functional pressure pot cover only is that it does not put water valve, after with water cooling, has directly held tank that water is outwelled to get final product with holding handle (9).

Structure according to above-mentioned multi-functional pressure pot cover, see the process of heating solid food again, be that example is illustrated still with 5 up voltage power pots, spherical surface diameter is 22 centimetres on its pot cover, about 380 square centimeters of entire area, if the tank frame is high 6 centimetres, then the volume in the interior space of tank is about 2280 cubic centimetres, the density of 100 ℃ saturated vapor is 598 gram/cubic meters, so if be full of in the tank saturated vapor its moisture quality be about 1.36 grams, in other words as long as the water that add more than 1.36 grams just can satisfy the needs of saturated vapor to the water number amount.The water that now adds 38 grams, because the tank bottom surface is domed, central authorities are high, so water distributes in the form of a ring, core is anhydrous.Tank bottom central part branch temperature must be higher than peripheral temperature in cooking pressure maintaining period like this; the cylindrical shape protective cover of pressure limiting vent valve plays the rise effect of similar chimney of heat of aggregation vapour, hot-air and water vapour is circulated in groove reach the effect of even heating solid food.
