Description

Lid lock device of electric rice cooker

The present invention relates to a locking device for selectively locking and releasing a lid of an electric heat cooker, and in particular, a pair of locking members installed on the inner lid to install an operation lever to which the handle is exposed to the outside and to be movable on the inner lid. By making the lock member move horizontally in accordance with the operation of the operation lever to selectively engage or disengage it with the inner container, it is easy to manufacture due to the simplification of structure, reduction of the incidence of failure, maintenance of appearance and handling Ease of, and possible to reduce the height of the rice cooker, to reduce the manufacturing cost.

Various types of structures are known for the locking device applied to the electric thermal pressure cooker, and one of them is the Japanese Patent Publication No. 61-41206. In this case, the inner lid is provided to maintain the airtightness, and at the same time, the locking and discharging discs are provided with locking protrusions that can be engaged with the locking protrusions formed at the periphery of the inner container. The inner lid, the handle, and the lock disc are in a disc state and overlapped with the assembly center axis on the center of the lid, and the weight is applied to the entire lid. Since excessive load is applied to the opening and closing of the lid, there was a high risk of failure. The contact area of the ruled and unlocked disc has a lot of frictional force, which requires considerable force to operate it, which makes it inconvenient to handle it. As the gap flows, there is a closed end where airtightness decreases.

In addition, if you look at the technical information known in the Korean Utility Model Publication No. 94-1932, there is an inner container with a radial projection formed on the circumferential edge inside the cooker body, and responds to the locking projection when the lid is opened and closed. In a conventional electric thermal pressure cooker equipped with another locking projection to be handled in the overlapping state by operating the handle exposed to the outside to close the inner lid against the inner container, the lid body constituting the lid And a locking projection corresponding to the locking projection of the inner container, and having a locking and unlocking rotary body in the form of a handle attached to the inner region of the guide member so as to be rotatable. Fastening part of the disc inner cover that can seal the upper edge of the inner lid to the outside of the rotating body It has been made in the binder as it is exposed, such that the following problems.

⊙ When opening and closing the lid, there is a need for handling troubles in that the locking projections of the inner container and the locking projections of the swinging rotor are alternated with each other, that is, they do not interfere with the vertical movement.

⊙ Since the locking projection and the fitting groove should be formed separately at the edge of the inner container, the hanging, and the coasting rotor, the manufacturing process is complicated, resulting in a decrease in productivity and an increase in the cost angle.

⊙ The handling area was inconvenient to handle due to the large frictional force due to the large contact area between the lock and coasting rotating body and the guide member, which caused the flow of the cooker body during the rotation of the rotating handle. Rotating handle should be turned while pressing the main body so that it does not flow.

The present invention has been devised to solve the above problems of the conventional structure, by installing an operating lever with a handle exposed to the outside on the inner lid and providing a pair of locking members in contact therewith, according to the operation of the operating lever. As the locking member moves horizontally and is selectively coupled or separated with the inner container, it is easy to manufacture due to the simplification of structure, reduction of failure rate, maintenance of simplicity of appearance, ease of handling and height reduction of rice cooker, and cost of manufacturing It is to provide a locking device that can save money.

Lid locking device of the electric thermal pressure cooker according to the present invention is a lid that the inner container (2) is seated inside the cooker body (1) and rotated open and closed about the fixing pin (3) and the inner lid (5) on the inner surface In the well-known electric insulation pressure cooker provided with (6); A pair of left and right locking members 7 which are installed on the upper surface of the inner lid 5 to allow horizontal straight movement with the arc-shaped latching jaw 7A and the contact surface 7B having a c-shaped cross section at the outer and inner ends, respectively ( 7`) and; Guide holes 8 respectively drilled in the locking members 7 and 7 ′ to guide the straight movement of the locking members 7 and 7 ′; A pair of guide pins 9 and 9 'fixedly installed on the inner lid 5 in a state of being fitted into the guide hole 8; A tension spring (10) fixed at both ends to the outer guide pin (9) and the locking member (7) (7`) to impart the movement force inwardly to the locking member (7) (7`); It is pivotally arranged on the inner lid 5 using the fixed shaft 12 and is formed integrally with a pair of wheat pieces 11A, 11B formed symmetrically about the fixed shaft 12 and the cooker main body 1 An actuating lever 11 having a handle 11C formed to protrude to the outside of the; A perforated inner hole 13 which is perforated to communicate with the inside horizontally on the outer surface of the rice cooker body 1 and has a vertical lever fixing groove 13 'connected to one end thereof; It is installed so as to be elevated by the ball spring 16 in the installation hole 15 formed directly below the lever fixing groove 13`, and the bullet for restraining the fixed state of the operating lever 11 is not released without permission. It is made by combining the foot openings 14, respectively.

* Unexplained reference numeral 20 in the drawings shows the locking jaw of the circumferential edge of the inner container (2).

The operational effects of the present proposal constituted as described above are as follows.

The solid line state in FIGS. 1 and 2 is a state in which the lid 6 is unlocked, that is, a state in which the locking jaw 11A is pulled out of the locking jaw 20 at the circumferential edge of the inner container 2. Locking member (7) (7`) guide pins (9) (9`) is in contact with the inner end of the guide hole (8) to stop further outward movement and the tension spring (10) is forcibly extended state , The handle 11C of the operating lever 11 is fitted into the lever fixing groove 13 ′ like the phantom line of FIG. To prevent the lock from being released.

To lock the lid 6 in this state, as shown in FIG. 2, when the knob 11C is turned in the direction of the arrow, the pressing pieces 11A and 11B of the actuating lever 11 are moved together with the imaginary line and at the same time, the tension spring 10 Since the locking member 7 (7`) is pulled in by the contracting force of), the locking jaw 7A wraps the locking jaw 20 of the inner container 2 like an imaginary line so that the lid 6 is locked. To lose.

On the other hand, in order to unlock the lid 6 in this state as in the beginning, press down the handle 11C to allow the entry into the inner cavity 13 for the first time and then turn it in the opposite direction to the arrow in FIG. (11) of the pressing piece (11A) (11B) is moved counterclockwise and at the same time the locking spring (7) (7`) is pushed out while the tension spring (10) is contracted, the locking jaw (7A) is the inner container ( It is to be separated from the locking step 20 of 2) and placed in the released state.

As described above, according to the present invention, the number of components required for locking is significantly reduced compared to the conventional structure, so that the ease of manufacturing and the failure rate can be reduced due to the simplification of the structure, thereby improving productivity and reducing manufacturing cost. It has the effect of increasing the reliability, and the small volume occupied by the locking device prevents unnecessary parts of the product, preventing the enlargement of the appearance, and also makes the contact area between the contact surface of the contact piece and the locking member extremely narrow, thus reducing the frictional force. It is possible to maintain the soft opening and closing without any effort to operate the lock member is less, it is possible to ease the handling.
