2. Description of the Related Art As a conventional rice cooker provided with a hook lever on the main body of the rice cooker for opening the lid with one touch, there is known one shown in FIG. That is, in FIG. 3, the rice cooker main body 101 is a body 102.
And an upper frame 104 and an inner frame 103 provided inside thereof. A heating element 105 for heating rice and a thermostat 1 for detecting the completion of rice cooking are provided on the inner bottom of the inner frame 103.
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 in the vicinity of the shaft portion 111, a damper 113 for cushioning a shock when the lid 108 is opened and a damper spring 114 are provided.

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.

In the above conventional rice cooker, since the hook lever 115 is attached to the body 101 by the shaft 116, the hook lever 115 is pressed so as to compress the biasing spring 117 during assembly. Since the shaft 116 must be mounted on the hook lever 115, there is a problem in assembling.
Since the mounting portion of 18 and the biasing spring 117 is on the opposite side to the shaft 116, there is a problem that the hook lever 115 becomes large.

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 has an upper surface opened, and a rice cooker main body provided with an upper frame at the upper surface opening, and an upper opening of the rice cooker main body. A lid body that opens and closes freely, a hinge portion that pivotally supports the lid body on one side of the rice cooker body, and a hinge portion that is located substantially opposite to the hinge portion and that includes the rice cooker body and the lid body. There is a hook lever to be engaged, the hook lever engages the rice cooker body and the lid body at the upper end, and the lower end is rotatably pivoted by being held by the body and the upper frame of the rice cooker body. It was designed to prevent a dangerous situation.

Action With the above configuration, the hook lever can be downsized and the assembling property of the hook lever can be improved.

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

FIG. 1 is a side view showing a rice cooker according to an embodiment of the present invention with a part thereof cut away, and FIG. In FIG. 1 and FIG. 2, the rice cooker main body 1 includes a body 2, an inner frame 4 which is located inside the body 2 and constitutes a storage portion for the pan 3, and an upper opening of the rice cooker main body 1. And the upper frame 5 installed on the upper frame 5, and the pot 3 is supported by being placed on a ring 6 provided on the upper frame 5. A lid 7 is pivotally supported on the upper part of the rice cooker body 1 by a shaft 9 of a hinge portion 8 so as to be openable and closable. Further, an opening / closing spring 10 is urged in the direction of opening the lid 7 at the shaft 9 portion.

On the other hand, a hook lever 11 for engaging the lid body 7 in the closed state is provided inside the rice cooker body 1 located on the side opposite to the hinge portion 8. As shown in FIG. 2, the hook lever 11 has a lower end 11 which extends horizontally and serves as a rotation shaft.
a is sandwiched between the hook lever supporting portion 12 of the body 2 and the supporting rib 13 of the hook lever from the upper frame 5 and is rotatably supported, and the inner surface of the hook lever 11 and the spring of the upper frame 5. An urging spring 15 urges the hook lever 11 between the contact surface 14 and the contact surface 14 in the outward direction of the body 2, that is, in the direction in which the upper end 11b of the hook lever 11 engages with an engaging portion of an outer lid described later. It is provided in. The lid 7 is composed of an outer lid cover 16 forming an outer surface, an outer lid 17 forming an inner surface, and an inner cover 18. Further, an inner lid 19 is provided on the lower surface of the inner cover 18.
It is provided so as to press against the pot 3 when the is closed. The outer lid 17 is provided with an engaging portion 20 that engages with a hook lever 11 for keeping the lid body 7 closed. A heating element 21 for heating rice and a thermostat 22 for detecting the completion of rice cooking are provided on the inner bottom of the rice cooker body 1.

In the rice cooker configured as above, the hook lever
When assembling the 11 part, as shown in FIG. 2, first, the hook lever 11 is inserted into the hook lever supporting rib 13 of the upper frame 5. In this case, the upper end 11b of the hook lever 11 penetrates the hole 5a provided in the upper frame 5, and the lower end of the hook lever 11 is inserted into the recess 13a of the hook lever supporting rib 13 of the upper frame 5. After that, the hook lever 11 and the spring contact surface of the upper frame 5
By attaching a biasing spring 15 between the upper frame 5 and the upper frame 5, the lower end of the hook lever 11 can be assembled.
Reference numeral 11a denotes a recess 13a provided in the hook lever supporting rib 13 of the upper frame 5.
And a concave portion 12a provided in the hook lever supporting portion 12 of the body 2 so as to be pivotally supported so as to be rotatable. With such a configuration, the hook lever 11 is connected to the body 2 of the rice cooker main body 1. It can be easily assembled with the upper frame 5. In addition, since the biasing spring 15 is located on the rear surface of the operation portion of the hook lever 11, the operation feeling is extremely good,
Moreover, the hook lever 11 can also be downsized.
