A kind of electric cooker minute-pressure structure
Technical field
The utility model belongs to the electric cooker technical field, specifically, relates to a kind of electric cooker minute-pressure structure.
Background technology
At present, electric cooker on the market adopts the exhaust mode of straight-line mostly, promptly on pot cover, be provided with a steam port, steam is directly discharged outside pot by steam port, though this mode is simple in structure, pot internal pressure can not effectively be controlled, and the careless slightly meeting of the user high-temperature steam of directly being discharged is scalded in addition, leave hidden danger, simultaneously the rice in the pot also can too much mouthfeel be bad because of moisture loses.
Some electric cookers adopt and do catch in steam valves, and steam is not discharged immediately, come distributing fast of cuisine steam, but the steam orifice of this structure can't effectively make generation minute-pressure in the electric cooker, and electric cooker can better not prevent that when boiling soup from overflowing.
The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of electric cooker minute-pressure structure is provided, and makes to produce minute-pressure in the electric cooker, and can prevent effectively that electric cooker soup when boiling from overflowing.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of electric cooker minute-pressure structure, comprise affixed roller cap and roller mount, be provided with roller in this roller mount, this roller mount and roller cap form the roller containing cavity, this roller cap is provided with steam vent, this roller mount bottom be provided with and stew in the venthole that is communicated with, this roller quantity of steam in pot is close to described venthole after a little while, with roller jack-up, steam was discharged from described venthole when quantity of steam was big in pot.
Further, also comprise affixed steam lid and steam seat, described roller cap and roller mount are located between described steam lid and the steam seat, and described steam seat is provided with described venthole, reaches and the interior exhaust passage that is communicated with of pot.
Further, described steam covers and is provided with opening, and described roller cap is located in this opening, and described roller cap and roller mount are fixed in steam and cover.
Further, described steam lid and steam seat junction are provided with sealing ring.
Further, be provided with the backflow sealing ring bottom the described steam seat.
Compared with prior art, the beneficial effects of the utility model are:
The utility model makes and produces minute-pressure in pot and since roller act on cooked food the time, can break bubble and reach effectively to prevent to boil and overflow soup, and it is simple in structure, economy is practicality again.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a three-dimensional exploded view one of the present utility model;
Fig. 2 is a three-dimensional exploded view two of the present utility model;
Fig. 3 is a three-dimensional exploded view three of the present utility model.
The specific embodiment
Fig. 1 is to shown in Figure 3, electric cooker minute-pressure structure described in the utility model comprises affixed steam lid 1 and steam seat 6, steam seat 6 be provided with and stew in the exhaust passage 8 that is communicated with, be provided with roller mount 4 between steam lid 1 and the steam seat 6, these roller mount 4 bottoms are provided with the venthole 41 that is communicated with exhaust passage 8, be provided with roller 3 in this roller mount 4, this roller 3 quantity of steam in pot is close to venthole 41 after a little while, only leave a little slit between roller 3 and the venthole 41, with roller 3 jack-up, steam was discharged from venthole 41 when quantity of steam was big in pot.
Roller mount 4 tops are provided with roller cap 2, roller cap 2 and roller mount 4 usefulness screw fixings are on steam lid 1, steam covers 1 corresponding roller cap 2 and is provided with opening 11, roller cap 2 tops are located in this opening 11, roller cap 2 is provided with steam vent 21, roller cap 2 and roller mount 4 affixed formation roller containing cavities, sealing ring 5, backflow sealing ring 7 are contained on the steam seat 6, steam lid 1 that installs and steam seat 6 are fastened i.e. assembling finish.
Use of the present utility model is:
After producing steam in the electric cooker, steam seals backflow sealing ring 7 jack-up earlier, steam will enter exhaust passage 8 from the exhaust outlet of steam seat 6 bottoms, because steam lid 1 is sealed by sealing ring 5 with steam seat 6, this moment, exhaust passage 8 interior steam were discharged by the venthole 41 of roller mount 4 bottoms, because roller 3 deadweights, roller 3 is close to roller mount 4 ventholes 41, only leave a little slit between roller 3 and the venthole 41, quantity of steam is not enough to jack-up roller 3 after a little while in pot, in pot quantity of steam when big with roller 3 jack-up, steam is by the venthole 41 of roller cap 2 bottoms, and 21 discharges of the steam vent on the roller cap 2, produce minute-pressure in pot thereby make, because the effect of roller 3, when cooked food, can break bubble and effectively prevent to boil and overflow soup.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or distortion are not broken away from spirit and scope of the present utility model, if these changes and distortion belong within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and distortion.
