Detailed Description of the Invention

 [Object of the Invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice cooker having a structure in which an opening force is applied to a lid by a spring.

[0002]

2. Description of the Related Art Conventionally, in this type of rice cooker, a heater is internally provided, and a lid for opening and closing a main body for accommodating a pot heated by the heater is pivotably installed. It is designed to be opened by the person lifting it by hand.
Thus, in recent years, for example, a torsion coil spring is attached to a portion of the lid that pivotally supports, thereby giving an opening force to the lid, thereby making it unnecessary to manually lift the lid, or to increase its operating force. Something designed to reduce it is considered.

[0003]

In the case of the one considered as described above, the torsion coil spring is, in detail, held by the holding member mounted from the inside of the main body at the pivotally supporting portion of the lid. It is considered to be installed, and the cover for covering the holding member is also considered to be mounted from the inside of the main body.

For this reason, the mounting of the holding member and the cover has a problem that the work is troublesome and the assembling property is poor.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a rice cooker which is convenient in that the lid can be automatically opened or lightly opened and which can be easily assembled. To provide.

[Configuration of Invention]

[0007]

In order to achieve the above object, in the present invention, an outer frame constituting the outside of the main body, an upper frame constituting the upper end surface of the outer frame, and a main body are internally provided. An inner frame, a hook installed in the inner frame, a lid for covering the upper opening of the hook, a hinge receiving portion formed on the upper frame for pivotally supporting the lid, and a spring that gives an opening force to the lid. And a holding member that is mounted on the hinge receiving portion from the outside of the main body to hold the spring, and a hinge cover that is also attached to the hinge receiving portion from the outside of the main body to cover the hinge receiving portion and the holding member. It is characterized by

[0008]

According to the above means, both the holding member and the hinge cover can be mounted from the outside of the main body, so that there is no trouble in mounting from the inside of the main body.

Further, since the hinge cover covers not only the hinge receiving portion but also the holding member, the structure can be rationalized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. First, in FIG. 1, 1 is a main body, and an outer frame 2 is an outer shell. The upper end surface is constituted by the upper frame 3. As shown in FIG. 2, the main body 1 is internally provided with an inner frame 4, and the inner frame 4 is internally provided with a pot 5 and a heater (not shown) for heating the same. Reference numeral 6 denotes an inner lid provided in an opening on the upper surface of the shuttle 5. Reference numeral 7 is a hinge receiving portion formed on the right side of the upper frame 3 in the drawing, and 8 is a claw hook portion formed on the other side of the upper frame 3 on the left side of the drawing. On the other hand, 9
Is a lid that covers the opening on the upper surface of the kettle 5. Specifically, this lid has an outer lid 10 and an inner lid 11, and a heat insulating material 12 and the like are arranged between both lids. . On the outer surface of the outer cover 10, the main body 1 of the handle portion 13 extending in a bridge shape in the radial direction from one location on the outer peripheral portion to one location on the opposite side.
4 is integrally formed, and a hinge piece portion 15 (see FIG. 4) is also integrally formed at one end portion of the handle portion main body portion 14. Thus, the hinge piece portion 15 is formed into the hinge receiving portion. Located outside the part 7 and then laterally between the hinge shafts 16
The lid 9 as a whole is pivotally mounted on the main body 1 so that the lid 9 can be opened and closed by being passed through. Reference numeral 17 denotes a hanging plate which is a holding member for a tension coil spring, which will be described later, and 18 is a hinge cover. The upper frame 3 and the hanging plate 17 are attached to the upper frame 3 with screws 19 so as to cover. On the other hand, reference numeral 20 denotes a lid locking device provided at a portion of the lid 9 opposite to the hinge piece portion 15, which also includes a base member 21 and a lock lever 22 in detail. The member 21 is placed on the other end of the outer lid 10 and fixed by a screw 23 passed from below the inner lid 11, and then the intermediate portion of the lock lever 22 can be pivoted on the base member 21 by a shaft 24. And a compression coil spring 25 is interposed between the lock lever 22 and the base member 21.
The claw portion 26 at the tip end is engaged with the claw hooking portion 8 to lock the lid 9 in the closed state. Here, the handle portion 13 has, in addition to the main body portion 14, a cover 27 for closing the open portion of the upper surface thereof, and as a whole has a hollow shape as shown in FIG. In the state before the cover 27 is mounted, a spring, for example, a tension coil spring 28 is arranged along the longitudinal direction of the cover 27, and one end of the spring 28 is hooked on the hanging plate 17 so that the hanging plate 17 17 is connected to the main body 1 and the other end is hooked on the base member 21 of the lid lock device 20 to thereby be connected to the lid 9 via the base member 21. It gives the opening power to 9.

Therefore, in the case of the present embodiment having the above-mentioned structure, when the lid 9 is held in the closed state by the lid lock device 20, the lock lever 22 is pressed and the claw portion 26 is hooked. When the closed state of the lid 9 is released by removing the lid 9 from the portion 8, the lid 9 is automatically opened by rotating about the hinge shaft 16 by the opening force given by the spring 28. It is not necessary to manually lift the lid 9 or the operation force thereof can be reduced, which is very convenient.

In view of the fact that the same convenience is obtained as described above, the hanging plate 17 as a holding member for holding the spring 28 and the hinge cover 18 for covering the hanging plate 17 are used particularly in this embodiment. Since both can be mounted from the outside of the main body 1, unlike the conventionally conceived, there is no trouble of mounting from the inside of the main body 1, and thus the assemblability can be improved.

Further, the hinge cover 18 covers the hinge receiving portion 7 and the hanging plate 17. Since one component can cover two components, the structure can be rationalized.
Can be simple.

FIG. 5 shows a different embodiment of the present invention. One end of the tension coil spring 28 is attached to the above-mentioned hanging plate 17 through a linear member 29 such as a wire or a string, and by extension, the main body. It is convenient to connect one end of the handle part 13 without any problems when the shape of the handle part 13 becomes complicated or when the inside of the handle part becomes narrow by doing so. It can be done.

Besides, the present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications within the scope of the invention.

[0016]

As is apparent from the above, according to the present invention, the outer frame forming the outer frame of the main body, the upper frame forming the upper end surface of the outer frame, the inner frame installed in the main body, and the inner frame are installed. A hook that covers the opening of the top of the hook, a hinge receiving portion that is formed on the upper frame for pivotally supporting the lid, and a spring that gives an opening force to the lid. A holding member for holding a spring mounted from the outside of the main body, and a hinge cover that is also mounted to the hinge receiving portion from the outside of the main body and covers the hinge receiving portion and the holding member are provided. Not only can it be automatically opened or lightly opened, but its convenience, in particular, can be easily assembled, but can be obtained with a rational structure.
