Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the installation of a heat-retaining heater in a cooking device having a heat-retaining function, such as an electronic jar, a rice cooker with a jar, and the like.

The installation of a warming heater in a conventional cooking device is the fourth step.
As shown in FIG. 5 and FIG. 5, a heat insulating heater 3 covered with an aluminum plate 2 is wrapped around the outer periphery of a cylindrical protective frame 1 which is placed outside a removable food container and attached to the main body of the device.
The ends were fastened and fixed with screws 4.

However, the temperature rises due to the heat generated by the heat insulating heater 3, and the aluminum plate 2 thermally expands in the length direction, increasing its diameter, causing it to come off the protective frame 1, or not being in close contact with the protective frame 1, resulting in heat transfer. There was a drawback that it made things worse.

Aluminum plates are still expensive, and a configuration in which the heater is covered with an aluminum plate makes it difficult to automate the work, making it expensive as a heat-retaining heater.

In order to eliminate these drawbacks, some cord-shaped heaters were wrapped around the protective frame while being glued directly to it, but in this case, the adhesive wrapping equipment became complicated, making it difficult to rationalize the process, and making repairs difficult. Another drawback has arisen, which is poor sex.

The present invention provides a heat-retaining heater! iIl! 7η゛Ij41/
The above-mentioned drawbacks of the conventional device are eliminated by attaching the device through the device.

An embodiment of the present invention will be described in detail below.

In the drawings, reference numeral 6 denotes a cylindrical instrument body, and 6 denotes a cylindrical protective frame mounted inside the main body 1, which is formed by drawing a thin metal plate. 7 is a rice cooking heater attached to the inner bottom of the protective frame 6;
8 is an inner pot detachably placed on the rice-cooking heater 7; 9 is an inner lid that covers the upper opening of the inner pot 8; 101d is an outer lid with a heat-insulating structure; 11 is a thermal reed switch for controlling heat retention; 12 13 is a controller for controlling the rice cooking heater 7; and 14 is a cord-shaped heat-retaining heater wrapped around the outer surface of the protective frame 6.

The installation configuration of this heat-retaining heater 14 will be described.

On the outer surface of the protective frame 6, bent parts 15°15 for locking are provided at the top and bottom.
For installation, the tool 16 is fixed by spot welding.

Locking tools 18 having hooks 17 are fixed to both ends of the heat-retaining heater 14. Symbol 19 is a spring inserted into the heat-retaining heater 14, and 2o is a protrusion formed on the outer surface of the protective frame 6 to prevent the heat-retaining heater 14 from shifting.

Now, to install one end of the heat-retaining heater 14, insert it into the bent part 15 of the tool 16 and connect this bent part 16 and the collar part 1 of the locking tool 18.
7, and while pulling the other end of the heat-retaining heater 14 against the elasticity of the spring 19, insert the locking tool 18 at the other end into the other bent part. to be locked.

With this configuration, the heat-retaining heater 14 can be kept in close contact with the outer wall of the protective frame 6 at all times due to the elasticity of the spring 19, and even if the heat-retaining heater 14 thermally expands due to a temperature rise, the spring 19 does not expand or contract. Moreover, since the end of the heat-retaining heater 14 is inserted through the bent portion 16 of the fitting 16 and slides, the end portion of the heat-retaining heater 14 is in close contact with the protective frame 6.

Note that in the above embodiment, the spring 19 is the heat insulating heater 14.
Although it is provided only at one end, it may be provided at both ends.

As described above, one aspect of the present invention is to provide a protective frame containing a cooking heater on which an inner pot is removably placed, and a locking tool for locking both ends of the heat-retaining heater wrapped around the outside of the protective frame. At least one end of the heat-retaining heater is slidably engaged with the locking tool through an elastic body, so that the heat-retaining heater is always in close contact with the protective frame to provide good heat retention. It is of great industrial value as it provides cooking equipment.

Claims (1)

[Scope of Claims] A protective frame containing a cooking heater on which an inner pot is removably placed is provided with locking tools for locking both ends of the heat-retaining heater wrapped around the outside of the protective frame. At least one end of the heat-retaining heater is slidably locked to the locking tool via an elastic body.
