Description

{SAFTY ASSEMBLY FOR INNER POT COVER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety structure of an inner pot cover, and more particularly, to a safety structure of an inner pot cover that prevents the rotation of a lock rim when the inner pot cover is detached.

Generally, an electric pressure cooker (for example, an electric pressure cooker) is a device that cooks food by heating the inside of the inner pot in a state in which the food material to be cooked is contained in the inner pot, thereby producing a state of high temperature and high pressure. Such an electric pressure cooker is often represented by an electric pressure cooker, but in recent years, it has a function of cooking various kinds of food in addition to rice, so that it is used for various purposes in accordance with the name of electric pressure cooker.

1, the electric pressure cooker includes a main body 1, an inner pot 2 accommodated in the main body 1, a main body lid 3 covering the main body 1, And a lid (4) coupled to the bottom portion to cover the inner pot (2).

Specifically, the main body 1 has heating means 5 and control means (not shown) for controlling the heating means 5 so as to heat the inner pot 2 accommodated therein. The main body lid 3 is coupled to the main body 1 by a hinge 6 so that the opened top of the main body 1 can be opened and closed.

As the inner pot 2 is heated by the heating means 5 of the main body 1 in a state of containing the food to be cooked, the interior of the inner pot 2 is brought into a state of high temperature and high pressure and cooked with a desired food. The inner pot cover 4 is provided with an inner pot seal 4a on the inner pot cover 4 so as to seal the inside of the inner pot 2 so as to prevent leakage of temperature and pressure due to the heating of the inner pot 2. [ .

On the other hand, such a conventional electric pressure cooker poses problems that the inner pot cover 4 can not be separated from the main body lid 3. That is, the necessity of the detachable structure of the inner pot cover 4 has been suggested so that the cooking by-products and the residue attached to the inner pot cover 4 can be cleaned after cooking.

In the structure for selectively removing the inner pot cover 4, the operation of the cooker is not performed in a state in which the inner pot cover 4 is not mounted, in order to prevent a safety accident of the cooker with high temperature and high pressure in advance A need for a safety structure is required.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a safety structure for an inner pot cover that is easy to install on a lock rim and prevents the lock rim from rotating when the inner pot cover is detached.

According to an aspect of the present invention, there is provided a safety structure for an inner pot cover of an electric pressure cooker provided with an inner pot cover at a lower portion of a lid body and a lock rim rotatably installed in the lid body to the left and right An upper plate coupled to the fastening hole by fastening means and having a pair of fastening holes formed at an upper portion of the lock rim; And an arm which is elastically supported on the upper plate by an elastic member and extends horizontally toward the lid body and interferes with a part of the lid body when the inner pot cover is detached, And a stopper member made up of a lifting post disposed vertically movably in the lid body.

A mounting protrusion for fixing one end of the elastic member may be formed on one side of the lifting post of the stopper member.

And a locking protrusion protruding upward may be formed on the upper surface of the lid body so as to interfere with the arm in a state where the stopper member is lowered.

The locking protrusion may be formed at one side of the locking protrusion so that the arm can be moved over the inclined surface in a state where the stopper member is lowered to enable rotation in one direction of the locking rim.

According to the present invention, it is possible to simplify the apparatus by providing a simple installation in the locking rim, and it is possible to rotate the locking rim only in a state where the inner pot cover is mounted, so that the inner pot cover is prevented from being cooked while being detached, .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 2, the lock rim 20 is rotated along the periphery of the lid body 10 to determine whether it is sealed with the inner pot.

3, the upper plate 32 is fixed to the upper surface of the lock rim 20 and the stopper member 30 is movable up and down the lock rim 20 at a lower portion of the upper plate 32 And is elastically supported by the spring 35 downward.

Specifically, the stopper member 30 is formed with an arm 33 extending from the upper end toward the lid body 10, and the arm 33 interferes with the latching protrusion 11 formed on the upper portion of the lid body 10 . On the other hand, the stopper member 30 has a vertically raised and lowered post 34, which is mounted vertically movably through the lock rim 20.

A spring mounting projection (36) is formed at one side of the lifting post (34) to which one end of the spring (35) is fixed. A spring 35 is mounted on the spring mounting projection 36 and an upper portion of the spring 35 is supported by an upper plate 32 fixed to the upper portion of the lock rim 20 by bolts 31 do. The stopper member 30 is pressed downward by the elastic force of the spring 35 so that the lifting post 34 of the stopper member 30 protrudes to the lower surface of the lock rim 20 .

7, a pair of fastening holes H are formed on the upper surface of the lock rim 20 and bolts 31a and 31b are fastened to the fastening holes H, respectively, as shown in FIG. 8 The upper plate 32 is fixed. That is, the upper plate 32 is fixed on the lock rim 20 so as to support the elastic force of the spring 35 at the lower portion of the lock rim 20.

On the upper surface of the lid body 10, a locking protrusion 11 protruding upward is formed to interfere with an end of the arm 33 when the stopper member 30 is lowered.

The stopper member 12 has a sloped surface 12 formed at one side thereof so that when the lock rim 20 is rotated counterclockwise, even if the stopper member 30 is in a lowered state, 33 ride over the inclined surface 12 of the locking projection 11 to enable the rotation of the locking rim 20 in the counterclockwise direction.

4, when the lock rim 20 is rotated in the clockwise direction, the arm 35 of the stopper member 30 is hooked to the tip end of the lock protrusion 11 corresponding to the opposite side of the inclined surface 12, The clockwise rotation of the rim 20 becomes impossible.

This structural operating principle can be set in the operating direction for closing and unlocking the lock rim 20 and the inner pot. That is, even when the inner pot cover 60 is removed, the rotation of the lock rim 20 in the opening direction becomes possible, and the opening of the cooker lid can be set to be possible.

The use state of the present invention having such a structure will be described. 3 and 5, when the inner pot cover 30 is mounted on the lower surface of the lid body 10, the stopper member 30 is in an elevated state. In this state, the arm 33 of the stopper member 30 floats above the locking projection 11 with a certain space, so that no interference occurs between them. Therefore, in this state, the lock rim 20 can be rotated in the left-right direction.

4 and 6, when the inner pot cover 60 is disengaged, the upward / downward post 34 is pushed upwardly (i.e., the inner pot cover is disengaged) Down.

4, the arm 33 of the stopper member 30 interferes with the locking projection 11, thereby preventing the rotation of the locking rim 20, The rotation of the lock rim 20 is prevented so that the lock rim 20 and the inner pot are not sealed. So that the inner pot 60 can be prevented from being cooked while the inner pot 60 is detached.

While the present invention has been particularly shown and described with reference to the particular embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
