Abstract

The utility model is an electric rice cooker capable of controlling pressure inside the cooker at a micro pressure, consisting of a shell (1), a cover body (2), an inner liner, an electric hot tray and a controlling device, wherein the electric hot tray is arranged at the bottom of the shell (1); the inner liner is arranged on the electric hot tray; the cover body (2) is a moulded component with an inner cavity (21), wherein a dump steam hole (22) is arranged on the cover body and the cover body (2) is arranged on the top of the inner liner and is hinged and connected to the upper part of the shell (1), wherein a float valve (3) which can keep the pressure inside the cooker at a micro pressure is arranged on the cover body (2) and is opposite to the dump steam hole (22). The utility model has the advantages that the adoption of the well-designed float valve as a structure of micro pressure controlling valve has assured the pressure inside the cooker to be stable, a good rice cooking, and a sound safety, as well as a simple structure and easiness to dismantle the cooker. Besides, the float valve is easy to wash because the valve body is in a shape of a bowl. The utility model is a micro pressure rice cooker with a reasonable structure, convenience and practicality, and can be accepted by a vast range of users.

Description

A kind of minute-pressure electric cooker

1, technical field:

The utility model is a kind of electric cooker, and particularly a kind of pot internal pressure of controlling is in the electric cooker of minute-pressure, belongs to the renovation technique of minute-pressure electric cooker.

2, background technology:

Commercially available electric cooker adopts the exhaust mode of straight-line mostly at present, promptly on pot cover, leave a steam port, steam is directly discharged outside the pot by steam port, though this mode is simple in structure, but pot internal pressure can not effectively be controlled, in addition, the high-temperature steam that the careless slightly meeting of user is directly discharged is scalded, and leaves hidden danger; Simultaneously, rice also makes its mouthfeel bad because of moisture loses too much in the pot, and the quality of rice reduces.Though also have a kind of electric cooker that minute-pressure power steam valve is installed in addition, because of the structure of its steam valve is complicated, dismounting inconvenience is difficult to can accept for the user.

3, summary of the invention:

The purpose of this utility model is to overcome above-mentioned shortcoming and provides a kind of simple in structure, and convenient disassembly cleans easily, and can guarantee that pot inner pressure keeps stable, security performance is good, can be the convenient and practical minute-pressure electric cooker of users' acceptance.

Structural representation of the present utility model as shown in Figure 1, include shell (1), lid (2), inner bag, electric hot tray and control device thereof, electric hot tray places the bottom of shell (1), inner bag places on the electric hot tray, lid (2) is for making the shaped component of inner chamber (21), which is provided with exhaust hole (22), lid (2) places the top of inner bag, and be hinged on the top of shell (1), wherein lid (2) is gone up, can be made pot internal pressure keep the float valve (3) of minute-pressure being equiped with the corresponding position of exhaust hole (22).

Above-mentioned float valve (3) comprises valve body (31), valve gap (32), floating plug (33), wherein floating plug (33) places in the set floating road (34), valve body (31) bottom, valve gap (32) is provided with some passages (32A), it is installed on the top of valve body (31), and valve body (31) holding is on the set mount pad (23) of lid (2).

Float valve is as the structure of minute-pressure control valve cleverly because employing designs for the utility model, and therefore, it is not only simple in structure, dismounting easily, and can guarantee that pot inner pressure keeps stable, and it is effective to cook, and security performance is good; In addition, because that the valve body of float valve is made is bowl-shape, so its easy cleaning; The utility model is a kind of convenient and practical, can be the minute-pressure electric cooker of users' acceptance.

5, the specific embodiment:

Embodiment:

For floating plug (33) is remained in the floating road (34), to guarantee the operate as normal of float valve (3), the top in above-mentioned floating road (34) and bottom are respectively equipped with and make floating plug (33) can not break away from the shelves post (35,36) in floating road (34).

Outside guaranteeing that steam in the pot can be discharged pot, the tubular that sidewall is provided with opening (34A) can be made in above-mentioned floating road (34).According to the processing conditions of manufacturer, and consideration user's hobby and needs, above-mentioned floating road (34) can be made cylindric, also can make prism-shaped, and the corresponding spheroid of making of floating plug (33) also can be made prism.In the present embodiment, for easy to process, above-mentioned floating road (34) is made cylindric, the corresponding spheroid of making of floating plug (33).

For the thin rice gruel that overflows from the gap is back in the pot from the bottom of valve body (31) swimmingly, with convenient for cleaning, above-mentioned valve body (31) can be made bowl-shape.

Install for convenient, the upper end of above-mentioned valve body (31) is provided with edge clipping (37), and it passes through edge clipping (37) holding in the counterbore of the set mount pad of lid (2) (23) outer surface.For guaranteeing that further valve body (31) is fixed on lid (2) securely, valve body (31) passes through thread connection with lid (2).

When the utility model uses, earlier the valve gap (32) in the float valve (3) is screwed on valve body (31), again valve body (31) is fixed on lid (2), food is put into inner bag, lid (2) is closed, the start-up control device, then the utility model is started working, because the sealing of lid (2) edge, steam drain is unique outlet of inner bag and lid (2) institute formation airtight container.When food does not reach boiling in pot, the deadweight of floating plug (33) makes it to be pressed on the shelves posts (35) of bottom, floating road (34), progressively rise with the steam pressure in the pot, after the weight of vapour pressure greater than floating plug (33), floating plug (33) is held up, pressure in the pot is big more, and floating plug (33) is high more by the height of jack-up, and at this moment steam gushes from the opening (34A) that floating road (34) sidewall is provided with, outflow along with steam, pressure in the pot progressively descends, and floating plug (33) progressively descends, until realizing sealing again, because constantly heating, vapour pressure in the pot rises once more, so repeats said process, thereby has guaranteed that pot inner pressure keeps basicly stable; In addition, the thin rice gruel that overflows from the gap enters in the bowl-shape valve body (31), and is back in the pot along the bottom of bowl-shape valve body.
