Abstract
A delayed pressure preservation cut-off device for an electric pressure cooker is characterized by comprising a connecting bolt communicated with an inner cavity of an electric pressure cooker, and a valve bonnet assembly, wherein a steam exhaust vent, a sealing board and a temperature control sheet are arranged in the valve bonnet assembly; a sealing surface of the sealing board is a plane, faces a steam inlet of the steam exhaust vent, and cooperates with the steam inlet of the steam exhaust vent to form a structure capable of pressing the steam outlet for sealing and being separated from the steam outlet for the releasing of exhausted steam; the temperature control sheet is positioned at one end of the sealing board, and is at a position where the sealing board pushes and presses the steam exhaust vent of the steam inlet with the temperature control sheet when the temperature control sheet is heated to deform. The delayed pressure preservation cut-off device for the electric pressure cooker has the advantages that the structure is simple and reasonable; the sealing performance is good; when cooked by the electric pressure cooker to boil, the rice in the electric pressure cooker continuously boils till grains of the rice are about to be water saturated, and then keeps a pressure preservation and stewing state; the grains of the rice, subjected to the cooking process, are soft and dry, and have a tough and chewy mouth feeling and remarkable fragrance of rice.
Description
Technical field
The utility model relates to electric cooking appliance technical field, particularly relates to a kind of electric pressure cooking saucepan time delay pressurize shutoff device.
Background technology
At present, electric pressure cooking saucepan is on the market because explosion prevention function needs, and its working procedure is all energising heating, to the of short duration boiling of food, produces pressure in pot, enters power-off packing state, and after pot inner pressure reduces, then energising is heated to power-off pressurize.Constantly circulation, until food boils, the process that boils like this, for the more soup group food of the moisture content that boils, is not only to have facilitated but also power saving, and for boiling rice, effect is not just so good, if while boiling rice, rice just seethes with excitement, electric pressure cooking saucepan just enters power-off packing state, and what now the grain of rice can only be static bubbles open in hot water.In the time that electric pressure cooking saucepan is switched on heating again, the rice in pot can not seethe with excitement again, and there is Rice & peanut milk on the rice rice grain surface cooking like this, and rice is not soft, moisture content heavy, there is no a meter fragrance yet.
Utility model content
The purpose of this utility model is just to provide one and can be contained on existing electric pressure cooking saucepan product, can change the interior shutoff device of electric pressure cooking saucepan time delay pressurize of the rice process that boils.
The utility model solution is such:
The utility model comprises the connecting bolt and the valve bonnet assembly that are communicated with pot of electric pressure inner chamber, valve bonnet assembly is provided with exhaust hole, sealing plate and temperature control sheet, the sealing surface of described sealing plate is plane, this sealing surface is the air intake to exhaust hole just, push down air intake with the air intake formation of exhaust hole and seal, leave the structure of air intake release steam discharge; Described temperature control sheet is positioned at one end of sealing plate, is in temperature control sheet heat when distortion by the position that promotes the air intake of pushing down exhaust hole with sealing plate.
Technical scheme also comprises more specifically: coordinate the sealing plate periphery sealing to become elastic construction with valve bonnet assembly with the air intake of described exhaust hole, keep sealing plate to leave the state of air intake under normal condition.
Further: described elastic construction is to be flanging or arc ring at the periphery of sealing plate, utilize the strain that flanging or arc ring produce to drive sealing plate to move.
The utility model has the advantages that simple in structure, good airproof performance, make electric pressure cooking saucepan boil rice when seething with excitement, allow pot interior rice boil to continuously the grain of rice by full of water part, enter again the vexed meal state of pressurize, the soft solid carbon dioxide of rice rice grain cooking through this process, entrance has chewiness, and have obvious rice fragrance, rational in infrastructure.

In accompanying drawing, the 1st, gland seat, the 2nd, valve bonnet assembly, the 3rd, temperature control sheet, the 4th, connecting bolt, the 5th, attaching nut, the 6th, plain cushion, the 7th, pot body sealing plate, the 8th, pressing plate, the 9th, steam exhausting way, the 10th, sealing plate, the 11st, steam exhaust device, the 12nd, exhaust hole, the 13rd, admission opening, the 14th, pot body, the 15th, pot cover.
Detailed description of the invention
As shown in Figure 1, 2, comprise the connecting bolt 4 and the valve bonnet assembly 2 that are communicated with pot of electric pressure inner chamber, valve bonnet assembly 1 is provided with steam exhaust device 11, sealing plate 10 and the temperature control sheet 3 with exhaust hole 12, it is characterized in that: the sealing surface of described sealing plate 4 is plane, this sealing surface is the exhaust hole 12 to steam exhaust device 11 just, push down air intake with the air intake formation of exhaust hole 12 and seal, leave the structure of air intake release steam discharge; Described temperature control sheet 3 is positioned at one end of sealing plate 10, is in 3 heats whens distortion of temperature control sheet by the position that promotes the air intake of pushing down exhaust hole 12 with sealing plate 10.
The periphery of sealing plate 10 is pressed into bending arc ring, keeps sealing plate 10 to leave the state of air intake under normal condition, is subject to produce distortion under the compressing of temperature control sheet, moves to the position of closing into exhaust hole 12.
Temperature control sheet 3 is positioned at one end of sealing plate 10, while being in the 3 heat distortion of temperature control sheet, will promote to push down exhaust hole 12 with sealing plate 4.
As shown in Figure 2, at normal temperatures, temperature control sheet 3 is presented convex, and sealing plate 10 freely covers at exhaust hole 12, and when electric pressure cooking saucepan is in the time normally heating, sealing plate 10 covers exhaust hole 12 and seals, and electric pressure cooking saucepan heats.
As shown in Figure 3, when pressure cooker receipt is to when boiling, back down sealing plate 10, high temperature pressure in pot enters valve bonnet assembly inside to crossing admission opening 13, heat is delivered to temperature control sheet 3, when temperature control sheet 3 reaches after critical-temperature, produces to the distortion pressing down, compressing sealing plate 10 seals exhaust hole 12, enters packing state.
After boiling, treat that kettle temperature drops to normal temperature, temperature control sheet 8 automatically restores and presents convex, releasing sealed plate 10.
