問題点があつた。 However, in this configuration, when the temperature rises due to heat generation from the heat retaining heater 3, the aluminum plate 2 thermally expands in the length direction and increases its diameter.
There have been problems in that it may come off from the protective frame 1, or it may not be in close contact with the protective frame 1, resulting in poor heat transfer.

いた。 Furthermore, in the past, for example,
As seen in Publication No. 79638, that is, as shown in FIG.
A heating element for a heat-retaining device is known in which a bullet 25 is suspended across locking holes 24, 24' provided at both ends of a metal annular body 23 having a cord-shaped heater 22 inserted thereinto. In this structure, since this heating element is fitted into the inner casing of the heat insulating container, there is a problem that the heating element protrudes into the heat insulating container and becomes an obstruction.
When the heating element deteriorates due to long-term use, there is a problem in that the heating element is displaced in the vertical direction.
本発明は上記の従来の問題点を解消するために
なされたもので、以下、本発明の一実施例を添付
図面にもとづいて説明する。 The present invention has been made to solve the above-mentioned conventional problems, and one embodiment of the present invention will be described below with reference to the accompanying drawings.

つけたコード状の保温用ヒータである。 In Figs. 1 to 3, 5 is a cylindrical instrument body, and 6 is a cylindrical protective frame mounted inside the instrument body 5. This protective frame 6 is constructed by drawing and forming 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 removably placed on the rice-cooking heater 7; 9 is an inner lid that covers the upper opening of the inner pot 8; 10 is a heat-insulating structure 11 is a thermal reed switch for heat retention control, 12 is an outer lid of the appliance body 5, 13 is a controller for controlling the rice-cooking heater 7, and 14 is a cord-shaped cord wrapped around the outer surface of the protective frame 6. It is a heater for keeping warm.
次に前記保温用ヒータ１４の取付け構成につい
て述べる。 Next, the installation structure of the heat-retaining heater 14 will be described.

た突起である。 First, a fixture 16 provided with upper and lower bent portions 15 for locking is fixed to the outer surface of the protective frame 6 by spot welding. A locking tool 18 having a flange 17 is fixed to both ends of the heat-retaining heater 14. Note that 19 is a spring inserted into the heat-retaining heater 14, and 20 is a protrusion formed on the outer surface of the protective frame 6 to prevent the heat-retaining heater 14 from shifting in the vertical direction.

係止する。 Now, attach one end of the heat-retaining heater 14 to the mounting tool 1.
The spring 19 is inserted between the bent portion 15 and the collar 17 of the locking tool 18, and the other end of the heater 14 is inserted into the bent portion 15 of the locking tool 18. The locking tool 18 at the other end is locked to the other bent portion 15 while being pulled against the elastic force of the locking member 19.

て摺動するので保護枠６に良好に密着する。 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 rise in temperature, the spring 1
It is absorbed by the expansion and contraction of 9, and the heat retention heater 1
The end portion of 4 is inserted into the bent portion 15 of the fixture 16 and slides, so that it is in close contact with the protective frame 6.

れた効果を有するものである。 As described above, according to the present invention, a protective frame containing a cooking heater on which an inner pot is removably placed has flanges fixed to both ends of a cord-shaped heat-retaining heater wrapped around the outside of the protective frame. A fitting having a pair of bent portions for locking a retaining locking device and a protrusion for regulating the vertical position of the heat-retaining heater are provided, and at least one end of the heat-retaining heater is connected through an elastic body. It is slidably locked to the bent part, and with this configuration, there is no problem that the heat-retaining heater protrudes into the protective frame and gets in the way, and the heat-retaining heater is made of an elastic body. Due to its function, it can always be brought into close contact with the outer wall of the protective frame, and as a result, good heat transfer is always obtained. In addition, even if the heat retention heater thermally expands due to temperature rise, it can be absorbed by the expansion and contraction of the elastic body.Furthermore, the heat retention heater can be installed using a flange-attached locking tool fixed to both ends of the heat retention heater, and a mounting tool. This can be done easily due to the relationship between the pair of bent parts provided on the protective frame, and since the position of the heat-retaining heater is regulated in the vertical direction by the protrusion provided on the protective frame, it cannot be displaced vertically from the predetermined position. It has various excellent effects such as eliminating
