Description

[Detailed Description of the Invention] The present invention relates to a top lid fixing device for a cooking appliance such as a gas rice cooker having a swingable handle.

Conventionally, the first lid fixing device of this kind has already been developed.
The one shown in the figure is known.

This consists of a pair of protrusions 11, 11 on the periphery of the upper lid 1.
On the other hand, a pair of bases 3, 3 having a pair of U-shaped cross-section recesses 31 which are open inward are provided at the upper end of the trunk of the main body 2, and the open parts of the recesses 31 are opposed inwardly. , one of the circumferential side walls of the concave portion is opened, and a handle 4 is swingably attached to the base.

In the above conventional one, the protrusions 11, 11 of the upper lid 1
If you shift the top cover from the bases 3, 3 and cover it with the top cover, and rotate the top cover 1 in this state, the protrusions 11, 11
are located below the presser pieces 32, 32 on the upper walls of the concave portions 31, 31, and the upper lid 1 is pressed against the main body 2 side.

In this case, when covering the top cover 1, it is necessary to set the top cover 1 to a specific position in advance.

In order to solve this inconvenience, the present invention aims to make it possible to directly press the top cover with a presser piece so that the top cover can be securely fixed by the presser piece no matter where it is set. .

The technical means of the present invention to solve the above problems is as follows. In a top lid fixing device that accommodates a cooking pot and fixes the top lid in relation to the main body body, at least the vicinity of the swing fulcrum at both ends of the handle is made into a flat plate-like part in the swing direction, and the main body body The pivoting fulcrum of a pair of presser pieces, which are swingably raised from the upper end of the part, is provided inside the vicinity of the pivoting fulcrum of the handle, and the presser pieces are bent inward from the upright part following the pivoting fulcrum and its upper end. The swinging range of the presser piece can be changed from an inclined position in which the upper part of the upright part of the presser piece protrudes outward from the swing locus of both ends of the handle to an inclined position in which it protrudes inward. At the same time, the presser piece is biased so that its upper part protrudes outward, and when the handle is in an upright state, the inner surface near the fulcrum of the handle is in contact with the outer surface of the upright part of the presser piece. The pressing part of the piece is made to come into contact with the upper edge of the periphery of the top lid in the crowned state.

When the handle is folded down, the presser piece is in a position where its upright portion is inclined outward from the swing locus of both ends of the handle due to the biasing force acting on the presser piece. Therefore, the upper cover can be attached to the main body without changing it and can be removed.

Next, when the handle is swung in the upright direction with the top lid covered with the main body, the presser piece that is slanted to the outside of the covered area of the top lid is erected in a direction perpendicular to this swinging direction. and a portion near the fulcrum of the handle are paired in a cam mechanism, and the presser piece is pushed inward by the handle.

When the handle is in an upright state, the inner surface of the handle and the upright part of the presser piece come into contact, and the tip of the presser part of the presser piece presses down the upper peripheral edge of the crowned top lid. maintained in condition.

When the handle is folded down from this state, both ends of the handle come off from the upright part of the presser piece, and the outward biasing force acting on the presser piece causes the pair of presser pieces to open from each other. Now the top cover can be removed.

In this way, by only swinging the handle, the pair of presser pieces can be set in the state in which they press the top cover and in the state in which they are opened. In addition, during these operations, the vicinity of the fulcrums at both ends of the handle and the presser piece are paired with each other due to the cam mechanism, but the vicinity of the fulcrums of the handle becomes a flat plate-like part in the direction of swing of the handle. Therefore, the above-mentioned pair becomes smooth.

The present invention has the following unique effects.

According to the above configuration of the present invention, when the top cover is fixed,
The handle is always in an upright position, and the swingable handle does not come into contact with the main body during heating (when in use). Therefore, even when cooking is complete, the temperature of the handle does not rise, so there is no risk of getting burned if you hold this part.

Furthermore, since the handle is always in an upright position when cooking is complete, it is easy to carry the cooking utensil including the main body.

Furthermore, since the holding piece can be set between the state in which it presses the top cover and the state in which it is released by only the swinging of the handle, the holding piece can also be brought into contact with the plate-shaped portion of the handle. This makes the operation smooth.

Hereinafter, details of embodiments of the present invention will be explained based on the drawings.

In this embodiment, the handle 4 is made by bending a band-shaped metal plate into a U-shape and using both ends as fulcrums, as in the conventional case, and the handle 4 is provided at the upper end of the body of the main body 2 together with a presser piece 32 to be described later. It is rotatably supported by a pair of bases 3, 3.

The presser piece 32 consists of an upright portion following the fulcrum portion and a pressing portion extending inward from the bent end 35 at its upper end, and has an inverted L-shape as a whole.
Hereinafter, the structure of this holding piece 32 and its vicinity will be explained by taking the mounting structure of one holding piece 32 as an example.

The presser piece 32 is attached to its fulcrum shaft and is biased by a spring 5 interposed between the presser piece and the base 3 so as to swing back outward. When opened to the outermost side, the upright part of the presser piece comes into contact with the outer part of the lip 33 of the upper end opening of the base 3, thereby setting the maximum opening angle to a predetermined value. There is. Furthermore, a covering member 34 made of synthetic resin is attached to the tip of the presser piece 32.
is attached, and the shape of this lower surface is made to match the cross-sectional shape of the upper peripheral edge of the upper lid 1. (FIG. 2) Next, in this embodiment, the bent end 3 of the presser piece 32 is
The straight portion of 5 or less is in contact with the lower end of the handle 4, and for this reason, a rib 41 is provided at the lower end. Therefore, in this case, when the handle 4 is rotated upward, the rib 41 and the presser piece 32 come into contact and press the presser piece inward.
(Fig. 3) The ribs are not necessarily necessary, and the presser piece 3
A part of the back side of the handle may be in contact with the lower end of the handle when the handle is in an upright state. In addition, instead of the rib, a synthetic resin coating 42 is provided at the lower end of the handle 4.
It is also possible to employ a configuration in which the metal presser pieces are fitted together, and in this case, when the metal presser pieces are used, it is possible to prevent the handle 4 and the presser piece 32 from being damaged due to contact between metals.
