Description

[Detailed explanation of the idea] The present invention relates to an improvement of a heated cooked rice container.

In the conventional cooked rice heat-insulating container, the lid 3 is attached as shown in Figure 5.
The bottom of the 0 is composed of a donut-shaped synthetic resin bottom cover 31 with a missing center portion and a disc-shaped heat sink 32 that covers the missing portion, and the inside of the lid 30 is filled with a heat insulating material 33. ing.

The lid heater 34 is supported by a disk-shaped heater support 35 and is fixed in contact with the upper surface of the heat sink 32.

Moreover, the outer periphery of the heat sink 32 is secured with screws 36, 36, . . .
... is fixed to the bottom cover 31.

In the lid body 30 having such a structure, the bolts 38 for elastically supporting the rice bowl lid 3T on the lower surface of the lid body 30 must be supported by the heat sink plate 32, and the bolts 38 must be supported by the heat sink plate 32 when the lid body is opened and closed. There is a problem in that a load is applied and the heat sink 32 is required to have strength.

Further, parts such as the heat insulating material 33 and the heater support 35 are required, leading to an increase in the number of parts and the number of assembly steps.

The present invention aims to solve the above problems, and the following are the first points.
DESCRIPTION OF THE PREFERRED EMBODIMENTS A cooked rice heat-insulating container according to an embodiment of the present invention will be described with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a container body consisting of an outer case 3 and an inner container 4 disposed inside the outer case 3 via a heat insulating material 14, and 2 is a container body that can be opened and closed with a hinge pin 15 relative to the container body 1. A lid body 5 is rotatably mounted, a rice bowl 5 is housed in the container body 1, and a rice bowl 6 is resiliently supported on the lid body 2 and seals the top of the rice bowl 5 when the lid is closed. Lid, 7II! an annular shoulder member connecting the upper parts of the outer case 3 and the inner container 4;
8 is a pressure regulating cylinder, 9 is a through hole for inserting a pressure regulating part, 10 is a rice cooking heater, 11 is a heat-retaining heater attached to the shoulder of the inner container 4, 12 is a lid heater, and 13 is the heat of the lid heater 12. It is a heat sink for dissipating heat.

The lid body 2 has an outer plate 16 made of synthetic resin on its upper surface and a bottom cover 17 made of synthetic resin on its lower surface, and has a space 18 inside.

A circular recess 19 is formed in the center of the bottom cover 17 to which the heat sink 13 is to be attached.

The heat dissipation plate 13 is formed into a thin disk shape from a light alloy material such as aluminum, and an annular lid heater 12 is attached to the outer periphery of the upper surface thereof.

The heat dissipation plate 13 is fixed in contact with the recess 19 of the bottom cover 17 via a sealing member 20 made of silicone gasket or the like. 21... and a bolt 22 for supporting the rice bowl lid 6 at the center.

In this way, the bolts 22 are attached to the bottom cover 17, and no load is applied to the heat sink 13 when the lid is opened or closed.

Furthermore, since the attachment means is located inside the lid heater 12, it is also possible to significantly reduce the diameter of the heat sink 12.

Furthermore, the bottom cover 17 and the outer panel 16 made of synthetic resin are present above the lid heater 12, which improves the heat insulation effect and eliminates the need for filling with a heat insulating material as in the conventional example.

FIG. 2 shows the main parts of a cooked rice heat-insulating container according to another embodiment of the present invention.

In this case, a shallow annular groove 19a is formed in the periphery of the recess 19 of the bottom cover 17, and the outer periphery of the heat dissipation plate 13 is abutted against the annular groove 19a via a sealing member 20 made of silicon packing or the like. I try to make myself accessible.

Further, an annular bent portion 13a rising upward is integrally formed on the outer peripheral edge of the heat dissipation plate 13, and the sealing member 20 is provided to cover the bent portion 13a.

That is, the bent portion 1 is inserted into the annular groove 19a through the seal member 20.
By abutting the heat dissipating plate 13, the positioning of the heat dissipating plate 13 can be performed.

Further, in the case of this embodiment, the lid heater 12 is covered and fixed to the upper surface of the heat sink 13 with aluminum foil 25 via double-sided adhesive tape 24, as shown in an enlarged view in FIG.

Incidentally, as shown in FIG. 4, the lid heater 12 may be held within a bend 113a of the outer peripheral edge of the heat sink 13.

Next, the effects of the cooked rice heat-insulating container of the present invention are listed below.

That is, according to the present invention, (1) A bottom cover 17 made of synthetic resin is provided on the bottom surface of the lid body 2, and a heat sink 13 equipped with an annular lid heater 12 is placed at the center of the bottom surface of the bottom cover 17. By fixing the heat dissipation plate 13 directly inside the lid heater 12, the number of parts and the number of assembly steps can be greatly reduced, since the lid insulating material and heater support in the conventional example are not required. Since it is fixed with screws 21, 21..., it is possible to reduce the diameter of the heat sink 13, which simplifies the installation, and also reduces the power consumption of the lid heater 12 by reducing the heat dissipation area. There are practical effects such as:
