Description

Pressure packing for electric insulation pressure cooker

The present invention relates to a pressure packing for an electric thermal pressure cooker, in particular, so that the user can continue to carry out the original function of the pressure packing to prevent the pressure packing from easily removed from the lid when cleaning around the pressure packing as a pressure packing deformation The present invention relates to a pressure packing for an electric thermal pressure cooker, in which an existing combined pressure packing is easily taken off as well as a new exchanged pressure packing can be easily assembled in a lid.

In general, the electric thermal pressure cooker used at home is capable of performing the cooking under high temperature and high pressure conditions for the cooking object loaded in the rice cooker using electric energy, and the electric thermal pressure cooker is charged with the cooking object. When the lid is closed for the inner container, the airtightness to maintain the high temperature and high pressure set in the cooking situation is an absolute requirement.

As a means for satisfying the requirements as described above, as shown in Fig. 1, coupling grooves 2 and 2a are respectively formed on the upper and outer peripheral edges of the lid 1, respectively, and on the inner upper end of the inner cylinder 3, respectively. An inclined surface 4 is formed, which is located between the lid 1 and the inner cylinder 3 to seal the pressure between the lid 1 and the inner cylinder 3 to prevent high pressure and high pressure from being released to the outside. It consists of (5).

The pressure packing 5 is made of an annular frame like the lid 1 and the inner cylinder 3, and the upper and outer edges of the pressure packing 5 are provided in the coupling grooves 2 and 2a of the lid 1. Coupling protrusions (7) (7a) that are forcibly fitted are formed to protrude in the upper and side directions of the inner surface of the lid (1), respectively, and the lower end is in close contact with the inclined surface (4) of the inner cylinder (3) The closed end 6, which essentially blocks the pressure from being released to the outside, is formed into a tetrahedron.

In order to use the conventional pressure packing 5 configured as described above, the pressure packing 5 is coupled to the inner surface of the lid 1 by slightly forcibly fitting the coupling protrusions 7 and 7a into the coupling grooves 2 and 2a. Let's do it. After the lid 1 is closed for cooking, the closed end 6 is closely contacted with the inclined surface 4 of the inner cylinder 3 by the closing operation of the lid 1, so that the high pressure and high pressure pressure are released to the outside. It is prevented from being cooked and the cooking is smoothly performed.

However, the conventional pressure packing (5) has the advantage that can be smoothly carried out by effectively preventing the discharge of high temperature, high pressure by the pressure packing (5) when using the electric thermal pressure cooker, but conventional When cleaning around the pressure packing (5), the pressure packing (5) is easily released from the lid (1) occurs, and as the pressure packing (5) is removed from the lid (1) the original function of the pressure packing (5) There was a disadvantage that this is greatly reduced.

In addition, since the pressure packing 5 as described above must be coupled to the lid 1 side using a separate fixing jig in its structure, assembly is inconvenient and assembly problems are greatly reduced.

Therefore, the present invention has been devised to fundamentally solve the problems of the prior art, and its purpose is to keep the pressure packing from the lid when the user cleans around the pressure packing so that it can continue to perform the original function of pressure packing. At the same time to provide a pressure packing for the electric thermal pressure cooker having a structure that the pressure packing can be easily assembled to the lid.

The present invention as a means for achieving the above object is a vertical wall bent downward to form a receiving groove having a predetermined size on the inner edge of the lid, and is fixed in the receiving groove and one side is in close contact with the vertical wall Surface is formed and the other end is composed of a pressure packing formed integrally with the locking end is fixed to the inside of the lid as a basic feature of the technical configuration.

(Example)

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a sectional view of the main part showing a state in which the pressure packing according to the present invention is coupled to the lid, Figure 4 is a perspective view of the pressure packing according to the present invention.

In the present invention, the inner cylinder 20 having an inclined surface formed on the inner circumference of the upper end, the lid 10 coupled to the inner cylinder 20, and the inclined surface of the inner cylinder 20 in a state of being inserted into and fixed to the inside of the lid 10, are in close contact with the inclined surface of the inner cylinder 20. It is composed of a pressure packing 30 to block the high temperature and high pressure generated during cooking to be discharged to the outside basically acts as conventional.

However, the present invention is to allow the pressure packing 30 to be easily assembled to the lid so that the receiving groove 11 having a predetermined size is formed on the inner edge of the lid 10 as shown in Figures 2 and 4 The vertical wall 12 bent downward, and the contact surface 31 is inserted and fixed to the receiving groove 11 and is in close contact with the vertical wall 12 is formed on the other side inside the lid 10 The locking end is fixed to the locking end 32 is formed of a pressure packing (30) formed integrally.

Figure 3 is a cross-sectional view showing another embodiment of the pressure packing according to the present invention, by forming a deformation preventing grooves (34, 35) at regular intervals on the outer peripheral surface of the closed end 33 of the pressure packing (30a), the closed end during use (33) is rolled inward by the deformation preventing grooves (34, 35) to prevent the occurrence of gaps on the inclined surface of the inner cylinder (20).

When the pressure packing 30 of the present invention configured as described above is coupled to the inside of the lid 10, as shown in FIG. 4, an adhesive surface 31 is formed on one side and the locking end 32 is integrally formed on the other side. As shown in Fig. 2, the packing 30 is pushed into the lid 10 and the inner receiving groove 11 into the lid 10, and at the same time, the contact surface 31 is closed by the number of the receiving grooves 11 of the lid 10. When the pressure wall 30 is pressed in close contact with the straight wall 12, the pressure packing 30 is tightly fixed in the lid 10 receiving groove 11.

As described above, the pressure packing 30 tightly fixed in the lid 10 receiving groove 11 is tightly fixed in the receiving groove 11 even when the body of the pressure packing 30 is pulled downward. Since the pressure packing 30 is not easily released from the inside of the lid (10). Accordingly, in order to remove the pressure packing 30 from the lid 10, first, the pressure packing 30 is easily lifted by lifting the lower contact surface 31 and pulling downward.

Since the pressure packing 30 is firmly coupled to the receiving groove 11 side of the lid 10 by the locking end 32 and the contact surface 31, even if the user cleans around the pressure packing 30. The packing 30 is not easily removed from the lid 10.

As described above, according to the present invention, since the pressure packing is structurally rigidly assembled in a state in which a close contact is fixed to the receiving groove formed in the lid and at the same time the locking end is restrained, The original function of the pressure packing can be continuously performed, and furthermore, it is not necessary to use a fixing jig to assemble the pressure packing to the lid as in the prior art, and the effect of the assembly of the pressure packing is improved.

The present invention has been described with reference to specific preferred embodiments, but the present invention is not limited to the above-described embodiments and should be made by those skilled in the art to which the present invention pertains without departing from the gist of the present invention. Various changes and modifications can be made.
