Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a hinge device for a removable lid of a cooking appliance used in a general household.

BACKGROUND OF THE INVENTION Generally, when using a small rice cooker to boil noodles or other foods other than rice, it is convenient to remove the lid. For this reason, cooking appliances equipped with removable lids have been developed.

Conventionally, the hinge device for the lid of this type of cooker was as shown in FIG.

That is, the hinge shaft 35 of the lid 34 is fitted into the recess of the inner wall of the hinge part 32 of the upper frame 31 made of resin, and the outer wall of the hinge lever 33 is fitted into the recess of the inner wall of the hinge part 32 of the upper frame 31 made of resin.
The hinge shaft 35 is rotationally supported by holding the hinge shaft 35 in contact with the inner wall of the shaft. The hinge lever 33 is housed in a holding portion 36 of the upper frame 31 so as to be vertically movable, and is biased upward by a spring 37.

The effects of the above configuration are as follows.

When the hinge lever 33 is lowered, the hinge shaft 3
The inner wall holding the lid 34 is removed, and the lid 34 can be removed from the upper frame 31. Further, once the hinge lever 33 is lowered, it is pushed upward by the spring 37, so that when the user releases the hand, the hinge shaft 35 can be rotatably held again by the hinge portion 32 of the upper frame 31 and the hinge lever 33.

Problems to be Solved by the Invention However, there was a problem in that the hinge portion 32 of the conventional structure protruded beyond the external shape of the vessel. One of the reasons for this will be described below.

That is, the upper frame 31 is generally made of resin, and therefore, in order to maintain the mechanical strength of the hinge portion 32 formed by a part of the upper frame 31, a certain thickness is required, and the hinge shaft is inevitably The center of 35 is located on the outer periphery of the vessel.

However, in recent years, as consumer needs have diversified and various designs have been required, there has been an urgent need for the hinge portion to be designed compactly. Further, there was a problem in that the weight was applied to the hinge lever 33 and the hinge lever 33 was easily damaged.

The present invention takes the above-mentioned conventional problems into consideration, and aims to provide a hinge device for a lid of a cooker in which the hinge portion does not protrude outward and the hinge shaft is firmly supported.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention forms a hinge member constituting the hinge part of the container body with a metal plate,
A hook part with an opening facing outward is formed at the upper end of the lid for rotatably holding the hinge shaft attached to the hinge part of the lid, and a hinge lever is provided to cover the opening of this hook part from the outer periphery of the container body, and the hinge lever Vertical ribs are provided on both side walls of the body, and grooves corresponding to the ribs are provided in the hinge portion of the main body that accommodates the hinge lever to hold the hinge lever in a vertically movable manner. The configuration is such that it is energized.

Function Next, since the hinge device of the lid of the cooker having the above structure uses a metal hinge member, it is relatively thin and mechanical strength is guaranteed, so that space can be saved. In other words, the center of the hinge shaft can be located closer to the inner periphery of the container than in conventional configurations, and as a result, the thickness of the hinge lever that comes into contact with the outer wall of the hinge member can be ensured, and even if resin is used, its mechanical strength can be maintained. Guaranteed. Further, according to this configuration, the position of the hinge axis of the lid is also shifted to the inner periphery of the container, and therefore, the strength of the hinge portion of the lid can also be ensured.

Embodiment Next, an embodiment of the present invention will be described based on the accompanying drawings.

In Figures 1 to 3, 1 is a rice cooker main unit, and the external shape of this main unit 1 is composed of each part of an outer lid 2, an upper frame 3, a main body 4, and a lower frame 5. A pot 6 is removably provided inside the pot 1. A hinge portion 7 is provided on one side of the upper end of the main body unit 1, and a hook portion 8 is provided at a position corresponding to the hinge portion 7. A stainless steel hinge plate 9 is attached to the hinge part 7 of the upper frame 3 with screws 20, and a hinge shaft 10 press-fitted into the hinge part 7a of the outer lid 2 is rotatably attached to the upper end of the hinge plate 9. A hook portion 11 facing outward from the opening is formed so as to be able to be held in place.
The hinge lever 12 is arranged so that its inner wall abuts against the outer wall of the hinge plate 9 so as to cover the opening of the hook portion 11 of the hinge plate 9. Vertical ribs 13 are provided on both side walls of the hinge lever 12, and a protruding portion as a spring holding portion 14 is provided below the bottom wall. The main body 4 includes a hinge lever storage section 1 that accommodates the hinge lever 12.
5 is provided, and this hinge lever storage part 1
5 is provided with a groove 16 corresponding to the rib of the hinge lever 12. Further, the spring holding portion 14
A spring 17 is attached to the hinge lever 1.
A spring 17 is interposed between the bottom wall of the main body 4 and the bottom wall of the hinge lever storage portion 15 of the main body 4.

With the above configuration, the operation of attaching and detaching the outer cover 2 will be described. When the hinge lever 12 is pushed down, the wall covering the opening of the hook portion 11 of the hinge plate 9 disappears, and the outer cover 2 can be removed. When installing, just follow the same procedure as above.
Hinge lever 12 bottom wall ~ hinge lever storage section 15
Since a spring 17 is interposed between the bottom walls, the hinge lever 12 once pushed down is also pushed back up by the spring pressure of the spring 17, and the hinge shaft 10 of the outer lid 2 is pushed back again by the hinge plate 9 and the hinge lever 12. can be held rotatably.

FIG. 4 shows another embodiment of the present invention. In this case, the tip of the hook portion 11' of the hinge plate 9' extends to the outer periphery of the main unit 1', and this extended portion has a cutout hole corresponding to the rib 18 provided on the upper part of the hinge lever 12'. 19, and in normal use, the hinge lever 12'
The ribs 18 of the hinge plate 9' are fitted into the notched holes 19 of the hinge plate 9'.

According to the above configuration, the upper end portion of the hinge lever 12' is fixed by the hinge plate 9', thereby improving mechanical strength.

Effects of the invention As is clear from the description of the embodiments above, the invention uses a metal plate as a hinge member and combines a hinge lever to suppress the hinge shaft fitted to the hook from the outside, saving space. This ensures mechanical strength and allows the outer lid to be held freely and rotatably safely and smoothly. Further, the outer cover can be easily attached and detached, and a compact outer shape can be constructed.
