Abstract

The utility model provides a pressure regulating, temperature displaying and safe pressure cooker. In the utility model, a pressure releasing shifting fork and a short shifting fork are installed in the housing of an upper handle on the basis of the original constitution of the pressure cooker, and a special purpose temperature gauge is provided with on the housing of a cooker lid. A sealing ring can be pushed off a sealing surface by the pressure releasing shifting fork to make the sealing ring have no function of sealing if the cooker lid is not closed in proper place when the utility model is used, and as a result, the pressure can not be raised. The residual pressure in the utility model can be released when the cooker lid is opened, which can ensure safety. In addition, users can directly watch temperature display by the temperature gauge, and cooking effect can be controlled well to prevent overpressure working.

Description

Pressure regulating, temperature displaying, safe pressure cooker

The utility model belongs to pressure cooker, is the improvement to existing pressure cooker.

Use so far for a long time though existing pressure cooker comes out, but still also exist some defectives, as: because a few users is when the working pressure pot, closing when cover, if not careful, easily causing to close and cover not in placely, thereby causing the accident.Also have when remaining residual voltage in the pot, at this moment, open pot cover, easily cause accidents such as scald, in addition, existing pressure cooker does not have temperature and shows, is difficult to grasp the cooking effect of food like this, simultaneously, is unfavorable for preventing the security protection of superpressure yet.

The purpose of this utility model is in order to overcome the problem of above-mentioned existence, a kind of pressure regulation, temperature display, safe pressure cooker to be provided.It is not in place and the phenomenon that has an accident when uncapping, can make a pot interior residual voltage release that it can avoid closing lid, avoids the generation of scald accident.And have temperature and show, make the user can grasp cooking effect, when superpressure, can in time find.

In order to achieve the above object, the utility model comprises upper and lower secondary handle, flame-arrester vent plug, pot cover, pot body, pressure-adjusting type pressure limiting valve, goes up lower handle, rubber seal, the protruding tooth of pot body, it is characterized in that a pressure release shift fork relies on the bearing pin of self to be installed in the housing of upper handle, the pressure release shift fork is made of a long shift fork and a short shift fork, long shift fork is positioned at the top of short shift fork, and a special-purpose thermometer is installed on the housing of pot cover.

After buckling pot cover, the position of long shift fork is corresponding with the rubber seal external diameter, and the position of short shift fork is corresponding with the outer rim of the protruding tooth of pot body.

Special-purpose thermometer is the thermometer that temperature-sensing element is made with the bimetallic material.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is principal section figure of the present utility model.

Fig. 2 is the profile of pressure release shift fork of the present utility model.

Fig. 3 is the user mode figure of pressure release shift fork of the present utility model.

(1) upper auxiliary handle; (2) lower auxiliary handle; (3) screw of handle; (4) packing ring; (5) sunk screw; (6) handle set; (7) aluminium rivet; (8) flame-arrester vent plug; (9) pot cover; (10) pot body; (11) pressure-adjusting type pressure limiting valve; (12) pot is calculated; (13) special-purpose thermometer; (14) upper handle; (15) rubber seal; (16) pressure release shift fork; (17) lower handle; (18) the protruding tooth of pot body; (19) long shift fork; (20) lack shift fork.

Referring to accompanying drawing, on the technical characterictic basis that former pressure cooker had, one pressure release shift fork (16) is housed in the housing of upper handle (14), it has a long shift fork (19) and a short shift fork (20), long shift fork (19) is positioned at short shift fork (20) top, after buckling pot cover (9), the position of its long shift fork (19) is corresponding to the external diameter of rubber seal (15), and the position of short shift fork (20) is corresponding to the outer rim place of the protruding tooth of pot body (18).One special-purpose thermometer (13) fixes by fastening nut and pot cover (9), and the dial plate of special-purpose thermometer (13) partly is located in the housing of upper handle (14).

Referring to Fig. 2, Fig. 3, buckle pot cover (9) back because the pot protruding tooth of body (18) protrudes from the basic circle part of a pot body (10), again since the position of short shift fork (20) and pot protruding tooth of body (18) so corresponding last, lower handle (14), when (17) closing up, the pot protruding tooth of body (18) will be lacked shift fork (20) and be headed in handle (14) housing, because it is long, short shift fork (19), (20) be one, thereby long shift fork (19) outwards produces around self bearing pin, because the position of long shift fork (19) is corresponding with the position of rubber seal (15), thereby long shift fork (19) is released rubber seal (15), thereby lose sealing function, on so just having guaranteed, lower handle (14), (17) do not overlap, rubber seal (15) is in leak condition, so can not boost, when maloperation, guaranteed safety.When upper and lower handle (14), when (17) overlap, short shift fork (20) contacts with pot body (10) basic circle outer rim, and long shift fork (19) is withdrawed from, and rubber seal (15) resets.When uncapping, rotate counterclockwise pot cover (9), short shift fork (20) slides to the protruding tooth of pot body (18) outer rim again, and long shift fork (19) pushes away rubber seal (15) the protruding tooth of pot body (18) plane once more, residual voltage in the pot is released, thereby avoided the generation of accident.

Special-purpose thermometer (13) dial plate divides three temperature look sections: 60 ℃-80 ℃ are green, are not have the temperature section of pressure; 80 ℃-120 ℃ is yellow, is the operating pressure temperature section; 120 ℃-140 ℃ is red, is the pressure and temp section that transfinites; In use, pointer is normal about 120 ℃, also is safe, if there is not stopping state, can not reach 130 ℃, and therefore, thermometer can not only be observed temperature, and grasping food is cooking effect, simultaneously, also is the safety assurance that prevents that superpressure from using.

Advantage of the present utility model is: it is not in place to close lid during use, pressure release shift fork (16) can push away sealing surface with rubber seal (15), make it not seal, thereby do not rise pressure, and pot is interior if any residual voltage when uncapping, and pressure release shift fork (16) can release residual voltage in the pot when uncapping again, guaranteed safety, special-purpose thermometer (13) can make user's temperature directly perceived show, grasps cooking effect, prevents superpressure work.
