It is equipped with 06 and is equipped with a removable rice cooker 107. 1
Reference numeral 08 denotes a lid body, which has an inner lid 109, and is hingedly supported by a shaft 111 on one side of the rice cooker body 101 so as to be openable and closable. Also, the lid 108 is always connected with the shaft 111.
A spring 112 for urging in the opening direction is provided, and a damper 113 for absorbing a shock when the lid 108 is opened and a damper spring 114 are provided near the shaft portion 111.

On the other hand, a hook lever 115 for engaging the lid body 108 in a closed state is provided with a shaft 116 and a biasing force inside the rice cooker body 101 located on the side opposite to the side on which the lid body 108 is pivotally supported so as to be openable and closable. Spring 11
7, the hook lever 115 is exposed to the outside from the side wall of the rice cooker body 101 as an operation unit 118 for pressing a part of the hook lever 115. Further, a hook 119 for engagement is provided on the lid 108 facing the hook lever 115. Then, by pushing the operation portion 118, the hook lever 115
The hook 119 is disengaged and the lid 108 is opened.

However, in the above-described conventional rice cooker, since the hook lever 115 is attached to the body 102 of the rice cooker body 101 by the shaft 116, a retaining structure for the shaft 116 (caulking,
(E-ring etc.) is not required separately, but since the operating portion 118 of the hook lever 115 and the mounting portion of the biasing spring 117 are on the opposite side to the shaft 116, there is a problem that the hook lever 115 becomes large. there were.

An object of the present invention is to provide a rice cooker that solves such problems.

Means for Solving the Problems In order to solve the above problems, the rice cooker of the present invention includes a hinge part that pivotally supports a lid body on one side of the rice cooker main body so as to be openable and closable,
A hook for engaging the rice cooker main body and the lid is located on the substantially opposite side of the hinge portion, and is pivotally supported on the upper frame by a hook shaft, and the side surface of the hook shaft is provided on the rice cooker. It is configured to be closed by a retaining rib protruding from the operation display portion provided on the main body.

Operation With the above configuration, the hook shaft retaining component is not necessary, and the hook is downsized, so that the configuration can be simplified.

Embodiment One embodiment of the present invention will be described below with reference to the accompanying drawings.

1 to 4, the rice cooker main body 1 is a body 2
And an inner frame 4 which is located inside the body 2 and constitutes a storage portion for the pan 3, and an upper frame 5 which is installed in an upper opening of the rice cooker body 1. A lid 6 is pivotally supported on the upper part of the rice cooker body 1 by a shaft 8 of a hinge portion 7 so as to be openable and closable. Further, the lid 6 is attached to the shaft 8 again.
An urging spring 9 for urging the valve is always provided.

On the other hand, a hook 10 for engaging the lid body 6 in the closed state is provided inside the rice cooker body 1 located on the side substantially opposite to the hinge portion 7.
Is provided. The hook 10 has a lower end 10a.
Is rotatably supported on the upper frame 5 by a hook shaft 11, and between the inner side surface 11b of the hook 10 and the spring contact surface 12 of the upper frame 5, an upper end 10c of the hook 10 has a lid body described later. A hook spring 13 is provided which constantly biases the engaging portion 6 in the direction of engaging the engaging portion.

The outer side surface 10d of the hook 10 is inclined so that the gap 14 with the upper frame 5 becomes narrower upward. Reference numeral 15 is a hook button provided on the upper front surface of the upper frame 5 so as to be vertically movable, and 16 is a hook lever pivotally supported by a hook metal fitting 17. The hook lever 16 is formed in a substantially U shape. Is
The hook side 16a located in the gap 14 and the hook button 15
Hook button side 16b having a hole 16c through which the core 15a of the
Is equipped with. On the hook button side 16b, hook button 1
The core portion 15a of 5 penetrates the hole 16c of the hook lever 16 and is inserted into the guide hole 17a of the hook metal fitting 17, and the pushing portion 15b of the hook button 15 is in contact with the upper surface of the hook lever 16. Reference numeral 18 denotes a hook lever spring provided between the hook lever 16 and the hook metal fitting 17 centering on the core portion 15a of the hook button 15, and the hook lever spring 18 makes the hook button side 16b of the hook lever 16 upward, that is, the hook. The button 15 is urged upward. At this time, the hook lever
The contact surface of the 16 with the hook button 15 has an inclination so that it becomes horizontal when the hook button 15 is pushed to the bottom.

The lid body 6 is composed of an outer lid 19 forming an outer surface, an outer lid cover 20 forming an inner surface, and an inner cover 21, and the lower surface of the inner cover 21 has the lid body 6 closed. The inner lid 22 is provided so as to be pressed against the pot 3 when turned on. The outer lid cover 20 is provided with an engaging portion 23 that engages with the hook 10 for keeping the lid body 6 in the closed state.

A heating element 24 for heating rice and a thermostat 25 for detecting the completion of rice cooking are provided on the inner bottom of the rice cooker body 1. 26
Is an operation display section, which is provided with a display section cover 27 on the inside, and is fixed to the body 2 from the front by screws 28. Reference numeral 29 denotes a retaining rib of the hook shaft 11 protruding inward from the display cover 27. The retaining rib 29 is provided so as to close both side surfaces of the hook shaft 11.

When assembling the hook 10 and the hook lever 16 in the rice cooker configured as described above, the hook spring 13 is attached to the hook 10 and attached to the upper frame 5, and the hook shaft
Insert 11 and fix. On the other hand, the hook lever 16 is rotatably supported by a shaft 16d on a hook fitting 17 in advance, and a hook lever spring 18 is mounted on the hook metal fitting 17. Finally, the core portion 15a of the hook button 15 is attached to the hook lever 16 and the hook. It can be easily assembled by fixing it to the upper frame 5 while passing it through the metal fitting 17. In addition, the operation display unit 26
By attaching the to the body 2, the hook shaft 11 can be prevented from coming off by the coming-off preventing rib 29 protruding inward from the display cover 27.

The operation of the above configuration will be described next.

When the lid 6 is to be opened, the hook button 15 is pushed downward in FIG.
b pushes the hook lever 16 against the spring force of the hook lever spring 18. As a result, the hook lever 16 rotates clockwise about the shaft 16d, and the hook side 16a moves upward. At this time, since the gap 14 between the hook 10 and the upper frame 5 is narrowed upward as shown in FIG. 3, the hook 10 is moved by the upward movement of the hook side 16a of the hook lever 16 so that the hook 10 is , It moves inward against the spring force of the hook spring 13, and as a result, the upper end 10 of the hook 10 shown in FIG.
Since c is disengaged from the engaging portion 23 of the outer lid cover 20, the lid body 6 is automatically opened by the urging force of the urging spring 9. Here, when the hook button 15 is released, the hook button 15 returns upward due to the biasing force of the hook lever spring 18, and the hook 15 also returns to the original position due to the biasing force of the hook spring 13.

EFFECTS OF THE INVENTION As is clear from the description of the above embodiments, the rice cooker of the present invention is provided with a hinge portion that pivotally supports the lid body on one side of the rice cooker main body so as to be openable and closable, and is located substantially on the opposite side of the hinge portion. Then, a hook for engaging the rice cooker main body and the lid is pivotally supported on the upper frame of the rice cooker main body by a hook shaft, and the side surface of the hook shaft is provided on the rice cooker main body. Since the hook is configured to be closed by the retaining rib protruding from the display portion, the hook can be easily assembled only by inserting the hook shaft and without requiring a retaining component for the hook shaft.
