Description

[Detailed description of the invention] The present invention relates to a lid for a jar rice cooker, etc., which has a lid pivotally supported on one side of the main body so that the lid can be opened and closed. This relates to the attachment of a handle cover that covers the upper opening of a bridge-shaped handle, and the purpose is to provide a lid body that improves the appearance and facilitates assembly work by setting the handle and handle cover to the same width. .

Conventionally, this type of handle cover has been embedded in both inner walls of a bridge-like handle and fitted and attached, or the handle cover has been simply flat. In the former case, there is a difference in level between the fitting part of the handle and the handle cover, which makes the handle difficult to grip, and it is difficult to create a sense of unity in terms of appearance, giving the handle a foreign feel. In addition, since the latter is flat, it feels weak in terms of strength and degrades the quality of the product.Furthermore, the mounting methods for these include providing a fitting protrusion and press-fitting, or providing a rib with a boss to connect the two. It was glued down. In particular, problems with adhesive fastenings have been apparent, such as poor workability and serviceability of the latch mechanism, and multiple configurations of hinge parts.

The present invention solves the above-mentioned conventional drawbacks, and a jar rice cooker will be described below as an embodiment of the present invention with reference to the accompanying drawings.

In the figure, 1 is an upper frame made of synthetic resin in which a latch receiving part 2 and a hinge part 3 are integrally formed, and a cylindrical exterior body 4 is press-fitted into the lower part of the outer periphery of this upper frame, and the lower opening of this exterior body The outer shell of the main body is covered by a bottom cover 5. Inside the exterior body 4, a bottomed cylindrical outer pot 6 is screwed to the upper frame 1 with an upper flange, and a heat-retaining heater 7 is provided on the outer periphery of the upper part.
A sheath-shaped rice cooking heater 8 is installed at the inner bottom. A heat insulating material 9 such as glass wool is provided in the gap between the exterior body 4 and the outer pot 6, and an inner pot 10 is suspended within the outer pot 6 so that it can be stored at a slight distance. The flange part is placed on the upper flange part of the outer pot 6.

Reference numeral 11 designates a completed lid body that covers the upper open portion of the main body, and 12 a bridge-like handle 13 that is used for carrying around with an open top surface, and an outer lid hinge portion at a portion corresponding to the upper frame hinge portion 3. 14 and a synthetic resin outer cover integrally formed with a latch attachment part 15; This is an outer lid cover made of synthetic resin. A rice cooking sensing thermostat 21 installed in a thermo cover 20 is provided in the center 19 of the outer lid cover 18 and is constantly biased downward by a compression spring 22. 23 is fixed with a screw 61 together with a seal packing 25 via an annular heat dissipating plate 24 to which a sealing pad 25 is fixed with adhesive.

Reference numeral 26 denotes a lid latch mechanism, in which a bearing plate 16 is fixed to the latch mounting portion 15 of the outer lid 12 together with the outer lid cover 18 with screws 62, and the latch lever 26a is attached to the shaft 26.
b and a spring 26c, and locks and releases the latch receiver 2 of the upper frame 1 by seesawing the upper opening/closing button 27 using the shaft 26b as a fulcrum and using the upper opening/closing button 27 as the operating section.

28 is a cross-sectional handle cover that covers the upper opening of the bridge-shaped handle 13 and the outer lid hinge portion 14, and 31 is an inner lid.

As described above, the lid body 11 is completed with the components of the outer lid 12, the heat insulating material 17, the outer lid cover 18, the thermostat 21, the heat sink 24, the lid latch mechanism 26, and the handle cover 28, and the hinge shaft 32 made of iron wire etc. The main body is opened and closed using the fulcrum as a fulcrum.

Next, the outer lid 1 which is a component of the lid body 11 mentioned above.
2 and the handle cover 28 will be explained in more detail.

In the outer lid 12, the outer lid hinge part 14 is U-shaped so as to sandwich the upper frame hinge part 3 from both sides,
A pair of through holes 37 into which the hinge shaft 32 is inserted are formed on both side walls, and a stopper portion 41 is formed which abuts against the holder cover 38 to maintain a predetermined opening/closing angle when the outer cover 12 is opened. , an engagement hole 42 is integrally provided inside this stopper portion 41 . Furthermore, the handle 1 is integrally formed with the outer lid 12.
3 has a U-shaped cross section, and a fitting step 43 having a predetermined width and height is provided at both upper ends of the opening along the entire circumference of the opening edge. A plurality of fitting pieces 45 extending outwardly and having an engaging part 46 on the outside, and an engaging part 47 provided near the latch attachment part 15 are integrally formed, and the outer lid 1
2 is formed.

The handle cover 28 has a cross-sectional shape, and has engaging protrusions 54 and 55 at the front end and rear end in the longitudinal direction, and the engaging portion 4 of the handle 13.
6, a plurality of engaging protrusions 56 are provided, and a predetermined gap a is maintained at the time of fitting and mounting, and the top and bottom,
Position regulating ribs 57 for regulating left and right deviations are provided on both inner walls. Note that 58 is a hole through which the opening/closing operation button 27 is inserted.

Next, the assembly procedure and structure of the above-mentioned lid 11 that covers the upper opening of the main body will be explained in more detail. First, related parts such as a thermostat 21 are attached to the center part 19 of the outer lid cover 18, and a lid heater 23 is installed. The heat dissipation plate 24 is then secured by tightening with a plurality of screws 61.

Next, the heat insulating material 17 is installed inside the outer lid 12, and with the outer lid cover 18 press-fitted to the outer lid 12, the lid latch mechanism 26 is tightened and fixed with the screws 62, and the lid body 11 is assembled. Then, while fitting the outer lid hinge part 14 to the upper frame hinge part 3 from the inside, the main body side lead wire is led out and the hinge shaft 32 is inserted.
The cover body 11 and the main body are pivotally supported by inserting and passing through the respective round through holes 37 and 39. The main body side lead wire and the lid side lead wire are connected in a cavity 40 formed at the base of the lid handle 13, respectively. Thereafter, the handle cover 28 is press-fitted onto the handle 13 and the outer lid hinge portion 14 is covered by the device. At this time, the handle cover 28 engages the engagement protrusion 54 on the front end side with the one end engagement part 47 of the handle 13, and engages the engagement protrusion 55 on the rear end side with the engagement hole 42 on the other end side. By press-fitting the handle cover 28 in such a manner that the other engaging protrusions 56 provided on the inner wall of the handle cover 28 engage with the engaging portions 46, the position regulating ribs 57 come into contact with the fitting stepped portions 43, thereby causing the necessary Further insertion is prevented.

As is clear from the above structure, according to the present invention, the handle and the handle cover each have a U-shaped cross section and are set to have the same width. Since they are press-fitted, they are strong and the handle cover can be attached and detached, saving parts, improving assembly workability and serviceability, and improving the appearance.
