TECHNICAL FIELD OF THE INVENTION
The present invention relates to a lid brake device for a rice cooker (including a rice cooker).
[0002]
[Prior art]
The lid, which is openably and closably attached to the rice cooker body, is urged in the opening direction by a hinge spring, so that when the user operates the hook release button, the lid is swiftly opened to reach the maximum opening angle. There is the inconvenience of rebounding when it arrives. In order to prevent the inconvenience, a brake device for sliding a part of the rice cooker body when the lid is opened has been conventionally provided (for example, see Japanese Patent Application Laid-Open No. 11-56614).
[0003]
In the above-described conventional brake device, a brake projection is provided at the center of the hinge shaft of the lid, and is fitted while slidingly contacting the fitting recess of the rice cooker main body, so that the brake is applied when the lid is opened. The reason why the brake device is provided at the center of the hinge shaft is to prevent imbalance in the braking force acting on the lid.
[0004]
[Problems to be solved by the invention]
When many electronic components are mounted on the lid of the rice cooker, a flat cable is wired between these components and the control unit of the rice cooker main body.
[0005]
However, as described above, when the brake device is provided at the center of the hinge shaft, when laying a flat cable, it is necessary to avoid the brake device and wire the flat cable. There is. It also goes against the demand for space-saving design.
[0006]
SUMMARY OF THE INVENTION It is an object of the present invention to provide a lid brake device which can be compactly designed without inconvenience in flat cable wiring.

[Means for Solving the Problems]
In order to solve the above problems, the present invention provides a rice cooker body in which a lid is attached to the rice cooker body by a hinge shaft so as to be openable and closable, and a brake part provided on the lid and a fixed sliding contact part facing the brake part are provided in the rice cooker body. A brake device for a rice cooker lid provided on the rotation radius of the brake part and sliding the brake part to the fixed sliding part before reaching the maximum opening angle of the lid, wherein the brake part is opposed to the brake part. A configuration in which the fixed sliding contact portions are provided near both ends of the hinge shaft is adopted.
[0008]
According to the above configuration, since the brake devices are provided separately at the left and right ends of the hinge shaft, the balance of the braking force acting on the lid is balanced, and the flat cable can be wired at the center of the hinge shaft. .
[0009]
As a specific configuration of the above-mentioned brake device, the above-mentioned brake part is formed of an elastic metal piece, and the two opposite pieces generated by bending the metal piece in an inverted U shape are directed inward and outward of the lid. And a locking portion is provided on the outwardly disposed outer piece, the locking portion is locked to the reinforcing metal of the lid, and the lower end of the inwardly disposed inner piece is bent inward horizontally. Then, a slide piece is formed, the slide piece is fitted to the resin member of the lid, and the fixed sliding contact portion is slidably contacted with the inner piece to apply a brake.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. As shown in FIG. 1, in the rice cooker of the embodiment, a lid 3 is attached to a rear end portion of a jar main body 1 by a hinge shaft 2 so as to be freely opened and closed. A pan 4 is detachably housed inside the jar body 1, and handles 5 are attached to both side surfaces of the jar body 1.
[0011]
The hinge receiving portion 6 of the jar body 1 supporting the hinge shaft 2 has a pair of support pieces 7, 7 on the left and right sides, and a reinforcing plate 8 is integrally provided therebetween. A recess 9 is provided at the rear end of each support piece 7, and both ends of the hinge shaft 2 are fitted and supported in the recess 9. The hinge shaft 2 is inserted through a pair of left and right hinge springs 11,11. One end of each hinge spring 11 is deformed downward against its elasticity (see the change from the two-dot chain line to the solid line in FIG. 1), and inserted into the insertion portion 12 of the reinforcing plate 8. The other end extends obliquely forward and is engaged with a part of the lid 3 to urge the lid 3 in the opening direction.
[0012]
As will be described later, a fixed sliding contact portion 20, which is a part of the brake device of the present invention, is formed on the outer surface of the upper end portion of each of the support pieces 7, 7.
[0013]
The hinge receiver 6 and the jar body 1 below the hinge receiver 6 are closed by a hinge cover (not shown).
[0014]
The lid 3 is obtained by fixing a metal reinforcing plate 14 on a lid lower member 13 and mounting a lid upper member 15 thereon. The rear end of the lower lid member 13 is recessed, and forms a lid hinge portion 17 together with hinge holes 16 provided in the left and right reinforcing plates 14.
[0015]
As shown in FIG. 2, a locking hole 18 is provided in the reinforcing member 14 at a position away from the hinge hole 16 by a predetermined distance, and a lower portion of the locking hole 18 is bent inward to cover the lower part of the lid. A slide receiving piece 19 extending on the member 13 is provided. The distal end of the slide receiving piece 19 is inserted into an inverted L-shaped guide portion 21 provided on the lower lid member 13.
[0016]
A brake portion 22 is provided in the portion of the locking hole 18 and the slide receiving piece 19. The brake portion 22 is disposed such that an opposing piece formed by bending a metal piece in an inverted U-shape is directed toward the inside and outside of the lid 3 along the axial direction of the hinge shaft 2. A locking portion 24 is provided by cutting and raising the outer piece 23 arranged outward. The locking portion 24 is fitted and locked in the locking hole 18. Further, the lower end of the inwardly disposed inner piece 25 is bent inward horizontally to form a slide piece 26. The slide piece 26 rests on the slide receiving piece 19, and its tip is inserted into the guide section 21.
[0017]
As shown in FIG. 4A, the positional relationship between the above-mentioned brake portion 22 and the above-mentioned fixed sliding contact portion 20 is such that the fixed sliding portion is positioned above the radius of rotation of the brake portion 22 when the lid 3 is opened (see the arrow in FIG. The sliding contact starts from the inverted U-shaped bent portion at the upper end of the brake portion 22 just before the contact portion 20 is present and reaches the maximum opening angle of the opening of the lid 3 (see (a) in FIG. )), While sliding on the inner piece 25, it is pushed into the outer piece 23 side. When the maximum opening angle is reached, the brake portion 22 reaches the lower end of the inner piece 25 (see also the two-dot chain line (b)). As the sliding contact progresses, the slide piece 26 retreats on the slide receiving piece 19 (see a two-dot chain line in FIG. 2B).
[0018]
The brake device of the embodiment is as described above, and the brake device constituted by the fixed sliding contact portion 20 and the brake portion 22 on the lid 3 slidingly contacting the fixed sliding contact portion 20 is provided near the left and right ends of the hinge shaft 2. Therefore, the flat cable 27 can be arranged at the center of the hinge shaft 2 as shown by a two-dot chain line in FIGS.
[0019]
As in the conventional case, when the user operates the hook release button (not shown) to release the engagement, the lid 3 is opened by the urging force of the hinge spring 11. However, before reaching the maximum opening angle, the brake portion 22 comes into contact with the fixed sliding portion 20 and starts sliding contact. A braking force acts on the lid 3 due to friction caused by the sliding contact. The braking force gradually increases as the opening angle increases, and becomes maximum at the maximum opening angle. As a result, the lid 3 stops slowly.
[0020]
In addition, since the above-mentioned braking force acts simultaneously at symmetrical positions near both ends of the hinge shaft 2, no imbalance occurs in the braking force acting on the lid 3.
[0021]
【The invention's effect】
As described above, according to the present invention, the flat cable can be arranged through the gap in the central portion of the hinge shaft, so that the flat cable is not overpowered and a special space is provided for the arrangement of the flat cable. Since there is no need, space can be saved. In addition, the effect similar to the conventional case is exhibited in that rebound at the time of the maximum opening of the lid can be prevented, and the braking force acts on the lid in a well-balanced manner, so that the lid can be opened and closed smoothly. Can be.
