The present invention relates to a lid structure of the electric thermal pressure cooker, in particular, to improve the cooking efficiency and reliability and improve the lid to an efficient structure, and when cooking, performs the function of inseparably combining the lid and the inner container The present invention relates to a lid structure of an electric thermal pressure cooker, which was developed for the purpose of establishing a locking device to a new structure, to promote the robustness of the coupling and the safety of the device.

In the conventional case, in use in an electric thermal pressure cooker, in order to close or release the close contact between the inner container and the lid seated in the rice cooker body to form a locking jaw in the inner container and the lid is the inner container locking jaw The locking jaw portion corresponding to the locking jaw portion and the inner container of the inner container is rotated as the lid is rotated as the lid is rotated in the left or right direction manually or mechanically.

As a result, the lid and the inner container were brought into close contact or released.

However, they are poor in reliability and safety because of their poor structure and bonding state, resulting in inconvenient use. In addition, in coupling (locking) the lid and the inner container in the above manner, not only the friction was severely generated due to the structural defect of the lid itself, but in some cases due to the weak bonding force between the lid and the inner container. The phenomenon of steam discharge occurred, which resulted in poor cooking and various defects in quality.

Therefore, the present invention improves the structure of the lid structure of the electric thermal pressure cooker and the structure of the locking device to close or close the lid and the inner container in an efficient structure to solve the conventional drawbacks as described above with the reliability and function of the function. When described in detail the configuration and operation effect by the accompanying drawings as designed to pursue the safety of the following.

In the electric insulation pressure cooker (A) structure consisting of the cooker body 100, the lid 200 and the inner container 300, the inner container 300 and the fixed disc 4 of the lid 200 in close contact Gear 6, 6 'and a locking device X for locking or releasing the locking jaw portions 5a and 300a of each of the rotating disc 5 and the inner container 300 for maintaining or releasing the state. The lid 200 includes a power transmission member 40 composed of a half moon gear 7 attached to the rotating disc 5 and a handle 8 protruded from the gear 6 of the power transmission member 40. Supported by the outer case 9 and the support member 10 so that the rotary disk 5 is rotated to the left or right in accordance with the rotation direction of the locking device (X) so that the locking jaw (5a) (300a) is caught or released On the other hand, the upper surface of the fixed disk (4) forms a plurality of projections (4a), the friction reducing means, to combine the packing (4b) of the steam leakage preventing means, the outer cage of the lid 200 (9) The upper surface of the high information (9a) is protruding, so that the fixed disk 4 is bolted, and between the upper surface of the packing (4b) and the lower surface of the rotating disk (5) coupled on the edge of the fixed disk (4) There is formed a predetermined interval (S) and the inner side of the outer case (9) of the lid 200 is provided with a guide member 11 is provided with a rotary disk (5) on the teeth (guide member) when rotating the rotary disk (5) It is configured to be guided.

Here, the shaft of the gear 6 is coupled to the handle 8 through the support member 10 and the outer case 9 of the lid 200.

The gear 6 'of the power transmission member 40 is rotatably fastened to the support member 10 as a two-layer gear structure. The half moon gear 7 is fixed to the rotary disk 5 by welding or other means. Reference numeral 12 is an exhaust valve.

Referring to the effect of the present invention configured as described above are as follows.

Closing the lid 200 of the present invention coupled to the upper portion that can be opened and closed on the cooker body 100 in a state in which the rotatable inner container 300 is seated in the cooker body 100 of the electric thermal pressure cooker (A), The locking jaw portion 5a formed at regular intervals on the edge of the rotating disc 5 of the lid 200 is positioned between the locking jaw portions 300a of the upper surface of the inner container 300 and at the same time as the upper surface of the inner container 300. The packing 4b joined on the edge of the stationary disk 4 is brought into contact.

At this time, the handle 8 of the locking device X is operated in the open position. As described above, in a state where the locking jaw portion 5a of the rotating disc 5 is located between the locking jaw portions 300a of the inner container 300, the user protrudes into the upper portion of the outer case 9 of the lid 200 ( 8) When the gear 6 of the power transmission member 40 connected to the shaft (to the handle) is rotated when it is rotated in the closing direction, the gear 6 engaged with the gear 6 in a state in which it is arranged as a supporting member 10 is rotated. Since the heavy gear 6 'is rotated to transmit the rotational force of the handle 8 to the half moon gear 7 fixed to the rotational disk 5, the rotational disk 5 is rotated while being guided to the guide member 11. The locking jaw portion 5a of (5) is positioned to match the lower portion of the locking jaw portion 300a of the inner container 300, and the locking jaw portions 5a and 300a of each of the rotating disc and the inner container are caught. (Figure 4)

Therefore, when using the electric thermal pressure cooker (A), the lid 200 is prevented from being separated from the inner container 300 so that the sealing force is maintained between the inner container and the fixed disc 4, and the packing 4b is the inner container 300 ) Is sufficiently close to close the gap to prevent the discharge of steam to learn the predetermined contents in the inner container (300).

In addition, by using the exhaust valve 12 in a state where the locking jaw portion 5a and the locking jaw portion 300a of the inner container 300 formed on the rotating disc 5 of the lid 200 are held. When the pressure is released and the lid 200 and the inner container 300 are released, the user locks the handle 8 of the locking device X in the opening direction, and the locking device X is closed. Since the rotation disc 5 is rotated in the reverse direction, the rotation disc 5 is guided by the guide member 11 to rotate so that the rotation disc locking jaw portion 5a is separated from the inner container locking jaw portion 300a. Each other is released.

In other words, the locking jaw portion 5a of the rotating disc 5 is located between the locking jaw portions 300a of the inner container 300, so that the user can easily open it.

On the other hand, in the locking or unlocking process as described above, a predetermined space is formed between the upper portion of the cooker main body 100 and the inner vessel 300, the locking jaw portion 5a of the rotating disc 5 is rotatable. Further, since the projection 4a formed on the stationary disk 4 and the rotational disk 5 are almost in line contact state, a predetermined interval S is formed between the packing 4b and the rotational disk 5 to rotate. Minimizes friction during rotation of the disc to avoid smooth operation. In addition, since the fixing disc 4 is bolted to the high information 9a protruding from the outer case 9 of the lid 200, the firmness of the lid 200 may be improved.

As seen from the above, the present invention can improve the cooking and quality and improve the reliability by using the lid and locking device of the electric thermal pressure cooker in an efficient structure, and also increase the sealing force between the lid and the inner container. It is to provide an electric thermal pressure cooker that can promote safety.
