Description

rice cooker

The present invention relates to a rice cooker, and more particularly to an exterior structure of a hinge portion provided in a rice cooker body.

Conventionally, in a rice cooker, a lid is rotatably attached to the rice cooker body by a hinge portion provided at the rear part of the rice cooker body (see, for example, Patent Document 1).

Japanese Patent No. 4027846 (page 3, FIG. 1)

In the rice cooker of Patent Document 1, when the lid is opened, the rear exterior portion of the lid moves to cover the exterior surface of the hinge portion as the lid is opened. At this time, as shown in FIGS. 5 to 8 described later, the gap between the rear exterior portion of the lid and the exterior surface of the rear portion of the hinge portion temporarily expands and then becomes narrow again. There was a problem that was easily caught.

This invention was made in view of such a point, and it aims at providing the rice cooker which can prevent a finger | toe being pinched in the clearance gap formed when opening a cover body.

The rice cooker according to the present invention includes a rice cooker body and a lid body rotatably attached to the rice cooker body by a hinge portion provided in the rice cooker body, and the lid body is a hinge portion when the lid body is opened. The outer surface of the hinge portion in the rice cooker main body has a shape bulging in an arc shape along the movement locus of the outer surface of the lid. is there.

According to the present invention, the exterior surface of the hinge portion is formed in a shape bulging in an arc shape that is close to the movement trajectory of the exterior portion of the lid, so that when the lid is opened, the exterior portion of the lid Since the gap between the hinge part and the exterior surface is kept at a constant distance, it is possible to prevent a finger from being caught in the gap.

It is sectional drawing of the rice cooker which concerns on one embodiment of this invention. It is the figure which showed the state in the middle of opening of the cover body of FIG. It is the figure which showed the state which the cover body of FIG. 1 was located in the open end. It is a principal part expanded sectional view of FIG. It is sectional drawing of the conventional rice cooker. It is the figure which showed the state in the middle of opening of the cover body of FIG. It is the figure which showed the state which the cover body of FIG. 5 located in the open end. It is a principal part expanded sectional view of FIG.

FIG. 1 is a cross-sectional view of a rice cooker according to an embodiment of the present invention. In FIG. 1, the left side is the front facing the user and the right side is the rear. In addition, in FIG. 1 and sectional drawing mentioned later, in order to make a figure intelligible, the end elevation of the cutting part is shown.
The rice cooker 1 includes a rice cooker body 2 having an opening on the upper surface and a lid 3 that opens and closes the opening of the rice cooker body 2. The lid 3 is rotatably attached to the rice cooker body 2 by a hinge part 4 provided at the rear part of the rice cooker body 2. The hinge portion 4 includes a hinge rotation shaft 5 that pivotally supports the lid body 3 and a hinel spring 6 attached to the hinge rotation shaft 5. Has been granted. Although not shown in detail, the hinge portion 4 is provided with a stopper (not shown) for restricting the open end of the lid 3, and the state is maintained when the lid 3 is positioned at the open end. It has come to be.

The inner pot 7 is housed inside the rice cooker body 2, and a heating coil 8 is provided below the inner pot 7 as a heating means for heating the inner pot 7. In addition, a latch mechanism 9 for opening and closing the lid 3 is provided on the front side in the rice cooker body 2, and a latch release button for releasing and engaging the latch mechanism 9 on the front exterior portion 20 of the rice cooker body 2. 10 is provided. When the latch release button 10 is pushed, the latch mechanism 9 is disengaged, and the cover 3 moves the hinge rotation shaft 5 as shown in FIGS. 2 to 4 to be described later by the urging force of the hinge spring 6 of the hinge portion 4. It rotates to the open end as a center, and the opening of the rice cooker main body 2 is opened.

Hereinafter, the structure of the characteristic part of the present embodiment will be described.
FIG. 2 is a view showing a state in the middle of opening of the lid of FIG. FIG. 3 is a view showing a state where the lid of FIG. 1 is located at the open end. FIG. 4 is an enlarged cross-sectional view of a main part of FIG. 1 and shows a change in the positional relationship between the exterior surface of the rear part of the hinge part and the rear exterior part of the lid body as the lid body is opened.
As shown in FIGS. 2 to 4, when the lid 3 is opened, the rear exterior portion 30 of the lid 3 moves over the exterior surface 21 at the rear of the hinge portion as the lid 3 is opened. The exterior surface 21 at the rear portion of the hinge portion has a shape that bulges in an arc shape along the movement locus L of the rear exterior portion 30 of the lid 3. Thereby, when the lid 3 is opened, the gap S (see FIG. 4) between the rear exterior portion 30 of the lid 3 and the exterior surface 21 at the rear of the hinge portion is maintained at a constant distance. It is possible to prevent a finger from being pinched. Note that the gap S is set to a distance that does not allow a finger to be caught.

Here, for comparison, a conventional rice cooker is shown in FIGS. As shown in FIGS. 5 to 8, in the conventional structure, the gap SA between the rear exterior portion 30A of the lid 3A and the exterior surface 21A at the rear of the hinge portion temporarily expands as the lid 3A rotates (FIG. 6). , See FIG. 8), and then narrowed (see FIGS. 7 and 8), so that it is easy to pinch the fingers.

Returning to the explanation of FIG. In the rice cooker body 2, a space portion 11 is formed below the hinge portion 4, and a control board 12 is disposed in the space portion 11. In this example, since the exterior surface 21 of the hinge portion 4 has a shape that bulges in an arc shape, even if the rear position of the space portion 11 is expanded to at least the same depth position as the tip 21a of the bulged portion, The volume of the space 11 can be expanded without increasing the size of the main body 2. In the example of FIG. 1, the rear portion of the space 11 is configured to be slightly behind the tip 21 a of the bulging portion. And the exterior part upper surface 11a of the space part 11 is made into the inclined surface which inclines toward the downward direction. As shown in FIGS. 3 and 4, the gap S <b> 1 between the rear exterior portion 30 of the lid 3 and the exterior top surface 11 a of the space 11 is widened in a state where the lid 3 is located at the open end. This is to ensure that the finger is not caught in the gap S1. Further, for the same reason, the lid is formed such that the lower surface 31 (see FIG. 4) of the rear exterior portion 30 of the lid 3 when the lid 3 is located at the open end is an inclined surface that is inclined upward. A rear exterior portion 30 of the body 3 is formed.

As described above, according to the present embodiment, the exterior surface 21 of the rear portion of the hinge portion is formed in a shape that bulges in an arc shape that is close to the movement locus L of the rear exterior portion 30 of the lid 3. Therefore, the gap S can be kept at a constant distance when the lid 3 is opened, and a finger can be prevented from being caught in the gap S.

Further, since the space portion 11 is provided in the dead space below the hinge portion 4 and the control board 12 is provided in the space portion 11, the overall size can be reduced.

In addition, since the outer surface 11a of the space portion 11 is inclined to be inclined downward, the rear exterior portion 30 of the lid body 3 and the exterior portion of the space portion 11 in a state where the lid body 3 is positioned at the open end. It is possible to prevent a finger from being caught in the gap S1 between the upper surface 11a.

Further, the rear exterior portion 30 of the lid body 3 is formed so that the lower surface 31 of the rear exterior portion 30 of the lid body 3 is an inclined surface that is inclined upward when the lid body 3 is positioned at the open end. Therefore, it is possible to prevent a finger from being caught in the gap S1 between the rear exterior part 30 of the lid 3 and the exterior part upper surface 11a of the space part 11.
