Description

[Detailed description of the invention] (Field of industrial application) The present invention is a structure for attaching a lid to a cooking device such as a rice cooker, and in particular, a structure for a hinge part of a rice cooker in which the lid of a rice cooker is rotatably attached to a shoulder body. Regarding.

(Prior Art) Conventionally, when attaching the lid of a cooker, such as a rice cooker, to the shoulder body of an exterior body, a through hole is provided at the handle base integrally formed in the lid body, and the handle is attached coaxially with the through hole. Insert a nut into the recess formed in one side wall of the base, cover with the handle cover, and assemble the lid. Then, after setting this lid on the shoulder body of the exterior body, insert the nut into the through hole and the bearing part of the shoulder body of the exterior body. A hinge pin is passed through the nut, and the tip of the hinge pin is screwed into the nut.

(Problem that the invention aims to solve) However, the conventional structure with a handle has a high height compared to the rice cooking capacity.
There was a problem in that the dimensions of the packaging box were large, resulting in high costs and shipping costs. In addition, it goes without saying that a handle cover is necessary to prevent the nut from falling out of the recess during the assembly process, and to solve the problem of spoiling the aesthetic appearance if the nut is exposed to the outside. , the nut may fall off when fitting the handle cover to the lid body.
There was a problem that it could not be discovered until the process of installing the hinge pin.

(Means for Solving the Problems) As shown in the figure, the present invention consists of a lid consisting of a lid main body 6 and a lid ring 7 fitted to the lid main body, which is hinged to a shoulder body 4 of an exterior body. In this cooker, the lid body 6 and the lid ring 7 are provided with hinge portions 21 and 28, respectively, and the hinge portion 2 of the lid body is provided with hinge portions 21 and 28, respectively.
1, an inner wall 23 is provided inside one of the side walls 22 or 24 at a predetermined distance from the side wall, a nut 34 is placed in a recess 33 formed between the inner wall and the side wall, and the recess 33 is Hinge part 28 of lid ring 7
It is closed with a flange 30 formed on the lid ring 7.
A hinge portion 28 is interposed between the bearing portion 17 of the shoulder body and the hinge portion 21 of the lid body, and a hinge pin is provided between the hinge portion 21 of the lid body, the hinge portion 28 of the lid ring, and the bearing portion 17 of the shoulder body. 20 are passed through and connected.

(Function) The lid of the rice cooker, etc. according to the present invention shares the impact that the hinge part of the lid body receives when the lid is opened, and prevents damage to the hinge part of the lid. fulfill the function of In other words, when an independent hinge part is provided on the lid body without using the handle base as a means of hinge-joining the lid, increasing the thickness of the hinge part increases the mechanical strength, but also reduces molding defects such as sink marks. If the wall thickness is made thinner, the mechanical strength will be weakened and the hinge will be damaged by the impact when the lid is released. By doing so, the impact received by the hinge portion of the lid body is alleviated. In addition, the recess provided in the hinge portion of the lid body and the flange provided in the hinge portion of the lid ring form a space for accommodating the nut, and the nut placed in the space falls off when the rice cooker is assembled. to prevent

(Example) Hereinafter, an example of the rice cooker according to the present invention will be described with reference to the attached drawings.

In the figure, 1 is the exterior body, 2 is the inner container, and 3
is the outer container, 4 is the shoulder body, 5 is the lid, and the lid 5 is the lid body 6
, a lid ring 7 , and a heat sink 8 , and a heat insulating material 9 is disposed between the lid body 6 and the lid ring 7 . The heat sink 8 is equipped with a heat insulating heater 10 and is screwed to the lid ring 7.
It is pressed into contact with the lid ring 7 via the seal ring 11. Reference numeral 12 denotes an inner cover mounting shaft attached to the center of the heat sink 8, 13 indicates an inner cover, and 14 indicates an elastic ring for attaching the inner cover attached to the inner cover.

As shown in FIG. 2, the shoulder body 4 has a bearing portion 17 formed between an inner annular flange 15 and an outer flange 16, and this bearing portion 17 has a side wall 17a and a side wall 17b (see FIG. 3). ) is formed with a through hole 18 for attaching the hinge pin 20 thereto.

The lid body 6 has a hinge portion 21 on its side wall,
An inner wall 23 is integrally formed inside the front side wall 22 of the hinge portion 21 extending downward at a predetermined distance from the front side wall 22. Disc-shaped protrusions 25 protruding inward are formed at opposing positions, and the inner wall 2
3 and the disc-like protrusion 25 have pin holes 26,
27 are provided.

The lid ring 7 is formed in an annular shape, and a pair of hinge parts 28 are formed on the side wall part of the lid ring 7.
A pin hole 29 is formed respectively, and
A flange 30 extending forward or backward is formed on the lower end side. In addition, this lid ring 7
Regarding the relationship between the hinge portion 28 of the lid body 6, the hinge portion 21 of the lid body 6, and the bearing portion 17 of the shoulder body 4, the bearing portion 17 of the shoulder body 4 is
Moreover, the distance between the outer wall surfaces of the hinge part 28 is set so that the hinge part 28 can be fitted into the hinge part 21 of the lid main body 6 (see FIG. 3). In addition, in the figure, 36 is a hinge cover, and 37 is a condensation catcher.

When assembling the lid and attaching it to the shoulder body 4, first, the lid locking mechanism 35 and other necessary parts are assembled into the lid body 6, the heat insulating material 9 is placed, and one side wall 22 of the hinge part of the lid body 6 is assembled. After placing the nut 34 in the recess 33 formed between the inner wall 23 and the inner wall 23, the lid ring 7 is placed and fitted onto the lid main body 6. At this time, the hinge part 28 of the lid ring 7 is fitted into the hinge part 21 of the lid body 6, the pin holes 26 and 27 of the lid body 6 and the pin hole 29 of the lid ring 7 are aligned on a straight line, and the recess 33 is inserted into the lid body 6. It is closed by the hinge part flange 30 of 7. Next, the seal ring 11 is set in the annular groove 31 of the lid ring 7, and the heat sink 8 is placed on top of the seal ring 11.
Cover and secure with screws. The lid 5 assembled in this way is set so that the hinge portion 28 of the lid ring 7 fits into the bearing portion 17 of the shoulder body 4, and the hinge pin 20 is inserted through the pin hole 27 of the lid body 6, and the tip end thereof is inserted. Assembling and attaching the lid is completed by screwing the screw cut into the nut 34 into the nut 34.

(Effects of the invention) As is clear from the above description, according to the invention, the lid body and the lid ring are each provided with a hinge portion, and the hinge portion of the lid ring is connected to the hinge portion of the shoulder body and the bearing portion of the lid body. While intervening,
The hinge part of the lid body, the hinge part of the lid ring,
Since the hinge pin is passed through the bearing portion of the shoulder body for hinge connection, the handle and therefore the handle cover can be omitted. In addition, the problem caused by omitting the handle, that is, the mechanical strength of the hinge part is weak and easy to break because it is not possible to form a thick hinge part like the handle base, can be solved by the hinge provided on the lid ring. This can be solved by reinforcing the problem. Moreover,
Even when attaching the lid ring to the lid body, the nut can be inserted into the recess with the lid body tipped over and fitted in that state, so the nut does not fall off as in the conventional case. Therefore,
The height of cooking appliances such as rice cookers can be lowered, and the packaging boxes for them can be made smaller and costs can be reduced.
Excellent effects such as reduction in transportation costs can be obtained.
