Abstract
The utility model relates to an inner cooker of a pressure cooker, which comprises a cooker wall and a cooker bottom which form an opening concave type container, wherein the cooker wall is provided with a supporting body which is formed from an integral ring body which is provided with a plurality of flange parts; the supporting body is fixed on the cooker wall; the ring body is formed by means of punching a strip-shaped material which is rolled; the outer periphery of the ring body, which is folded toward the cooker bottom, is provided with a reinforcing wall. By the cooker cover and the inner cooker which are directly buckled, the utility model can ensure that the inner cooker of a pressure cooker can not be deformed under stress. Simultaneously, the utility model has the advantages of production cost reduction and simple and reasonable structure.
Description
Technical field
The utility model relates to the interior pot of a kind of pressure cooker, particularly pressure cooker.
Background technology
Existing inner tube of pressure cooker, as Chinese patent CN02123616.X, name is called a kind of electric pressure, and it is the technical scheme that discloses interior pot and cooker lid locking device.Comprise have hold the interior pot for the treatment of Stewed Dish, and support in the body of interior pot support sector of pot; The top heating plate that the interior pot of control on demand opens and closes; Can with the locking device of interior pot flange part lock fit; And pot is put into the guider of pot support sector in the guiding, and this guider is pot support sector upper end raises up in being arranged on locator protrusions, and be arranged on insertion section on the interior pot flange part corresponding to locator protrusions and shaping.In not damaging, can make guider easily under the pot outward appearance prerequisite like this, its locator protrusions and interior pot of support sector become one, and make locator protrusions protruding upward from interior pot of support sector edge, on interior pot flange part, be formed with one, that can make the corresponding insertion of locator protrusions with it patchhole simultaneously, and can reduce corresponding welding sequence, and then has the effect that can reduce the activity duration and reduce production costs.
This patent interior pot has been described and the locking device that is mated between relation, have insertion section on the flange part to insert patchhole in the pot cover on the interior pot, thus locking pot cover device.Be extruded with the insertion section and make interior pot stressed limited, for the pressure variation of pressure cooker, adherence pressure pot operating efficiency has certain influence.When the increase to some extent of the pressure that increases this pressure cooker, the pressure of the above-below direction in the outside expansion of power, particularly vertical and horizontal line.And stress point produces the phenomenon of pressure release, gas leakage even blast thereby maximum possible makes inner tube of pressure cooker be out of shape on the interface portion of the insertion section on the inner tube of pressure cooker flange part and this flange part.Manufacturer will produce interior pot with thicker material in order to overcome above-mentioned phenomenon, and so, the production difficulty strengthens, and production cost increases.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming, can directly fasten by pot cover and interior pot and provide a kind of, guarantees that inner tube of pressure cooker is stressed and indeformable, has simultaneously to reduce production costs simple and reasonable inner tube of pressure cooker.
For realizing the purpose of this utility model, this inner tube of pressure cooker comprises pot wall and the bottom of a pan, the pot wall and the bottom of a pan constitute the matrix container of an opening, and the pot wall is provided with a supporting mass, are that the circle body of an integral body constitutes, circle body is provided with several flange parts, and supporting mass is fixed on pot wall.Wall upper opening place is provided with the pot mouthful flange part on outside anti-limit, and supporting mass is located at a pot wall top, and the top of supporting mass is near the bottom of pot mouth flange part.The formed external diameter of the flange part of supporting mass is bigger than pot mouthful flange part external diameter.Supporting mass by the rivet rivet clasp on the external wall of pot.The circle body internal diameter of supporting mass is slightly less than a pot wall external diameter, tightly is placed in outside pot wall.Be rolled into circle body by strip material, be stamped to form, the neighboring is folded to place, the bottom of a pan and is provided with a reinforced wall.The flange part that is provided with on the circle body of supporting mass is positioned at the circle body upper end or is positioned at the circle body bottom.
The utility model structural design advantages of simple is not a kind of labyrinth, only needs a circle body with supporting mass to be placed on pot wall, and supporting mass is used to bear the pressure of whole interior pot.Because the stress point of pot body was in the pot notch portion, so the thickness of pot will be used thicker material in the past.And supporting mass is arranged on pot wall now, can bear bigger power, therefore than the also thin 0.3-0.5 millimeter of former thickness, even also will approach.Form low, the minimizing activity duration and easy to use of cost.The transformation of inner tube of pressure cooker makes it more sturdy and durable.When guaranteeing that pot inner pressure rises, it is good that interior pot and pot cover keep fastening, and interior pot fastens the edge phenomenon that can not deform, and improves security.

Specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
In the accompanying drawing: 1, supporting mass; 2, the flange part of supporting mass; 3, the flange part of pot mouth; 4, rivet; 5, the circle body of supporting mass.
As shown in Figures 1 to 3, inner tube of pressure cooker of the present utility model comprises pot wall and the bottom of a pan, the pot wall and the bottom of a pan constitute the matrix container of an opening, and the pot wall is provided with a supporting mass 1, and supporting mass 1 is that the circle body 5 of an integral body constitutes, circle body 5 is provided with several flange parts 2, and supporting mass 1 is fixed on pot wall.Circle body 5 is shared pot mouthful suffered pressure.Pot wall upper opening place is provided with the pot mouthful flange part 3 on outside anti-limit, and above-mentioned supporting mass 1 is located at a pot wall top, and the top of supporting mass 1 is near the bottom of pot mouth flange part 3.Supporting mass 1 is the compression capability that increases the pot body equally.The flange part 2 formed external diameters of supporting mass 1 are bigger than pot mouthful flange part 3 external diameters.
The circle body 5 of supporting mass 1 can be by rivet 4 rivet clasps on the external wall of pot, or the circle body 5 of supporting mass 1 is manufactured internal diameter is slightly less than a pot wall external diameter, utilizes stamping technology that the circle body 5 of supporting mass 1 tightly is placed in outer wall of wall.
The circle body 5 of supporting mass 1 can be stamped to form by board-like material, or is rolled into circle body by strip material and is stamped to form.
The flange part 2 that is provided with on the circle body 5 of supporting mass 1 is positioned at circle body 5 upper ends or bottom, and circle body 5 neighborings are folded to the bottom of a pan or a pot mouthful direction place is provided with a reinforced wall, are used to increase the supporting mass compression capability.
