A small diameter bottomed inner cylinder 2 also made of stainless steel is disposed inside a bottomed outer cylinder 1 made of stainless steel, and between the bottomed outer cylinder 1 and the bottomed inner cylinder 2. A circumferential gap 3 and a bottom gap 4 are provided, and a heat insulating material 5 ′, 6 ′ is filled in the circumferential gap 3 and the bottom gap 4 to form a circumferential heat insulating section 5 and a bottom heat insulating section 6. 5 air-insulating circumference without the heat-insulating material 5 'around the lower part
An air gap 7 is provided, and the heat insulating material 6 ′ is provided above the bottom heat insulating portion 6.
An air-insulated bottom gap 8 without air is provided.
And the air-insulated bottom gap 8 are provided in communication with each other, and the heater 9 having the upper surface formed in the flat portion 9 ′ abuts the flat portion 9 ′ on the lower surface of the bottom plate 2 ′ of the bottomed inner cylinder 2 by the support beam 10. The thermistor 11 is attached to the upper part of the air-insulated bottom gap 8 , and a thermistor 11 is attached to the middle outer peripheral surface of the bottomed inner cylindrical body 2. Provided in a cooking pot.

The temperature setting controller 13 shown in FIG.
The heater 9 (preferably a multi-ring type spiral heater) is employed, adopting a dial rotation method also serving as an F switch, having a temperature display section 14 for displaying the set temperature held by the thermistor 11 and juxtaposed. As shown in FIG. 1, a plurality of nichrome wires each having a flat portion 9 'formed at the top as shown in FIG. 1 are used, and the heater terminals 9 "are connected to heater terminal connecting portions 16 provided inside the socket fitting portion 15, and flattened. The part 9 ′ is brought into contact with the bottom surface of the bottomed inner cylindrical body 2, and the 200 V three-phase three-wire 7.
An embodiment using a 5KW heater 9 is shown.

It is desirable to provide a caster 17 with a stopper at the bottom of the bottomed outer cylinder 1 to facilitate movement.

In the drawing, reference numeral 18 is a handle, 19 is a thermistor mounting opening with a closing plate, 20 is a lid with a handle 20 ', and a clip device 21 which is pulled and fixed at two places on the left and right sides by a knob piece for preventing sliding movement. Is attached.

[0020]

Since the present invention is constructed as described above, a small-diameter stainless steel bottomed inner cylinder is disposed inside a stainless steel bottomed outer cylinder, and the stainless steel bottomed outer cylinder is formed as follows. A circumferential gap and a bottom gap are provided between the bottomed inner cylindrical body and a heat insulating material is filled in the circumferential gap and the bottom gap to form a circumferential heat insulating portion and a bottom heat insulating portion. Air insulation without the insulation material around the entire circumference
Peripheral voids are provided, and there is no heat insulating material above the bottom heat insulating part
An air-insulated bottom gap is provided.
The bottom gap is provided in communication with the heater, the upper surface of which is formed in a flat portion, the flat portion is held in contact with the lower surface of the bottom plate of the bottomed inner cylinder, and the heater is attached to the upper portion of the air-insulated bottom gap , and attaching a thermistor on the outer peripheral surface of the bottomed cylindrical member, the heaters
The following features are exhibited because the temperature setting control unit is provided in the unit.

[0021] For example, a shank pot for making soup or boiling various kinds of soup, which has been called a conventional shank pot, is only a single aluminum or stainless steel plate tall pot.
The present invention is formed in a double structure of a bottomed outer cylinder and a bottomed inner cylinder,
Excellent heat efficiency because a thick heat insulating material is interposed in the meantime,
In addition, it becomes a cooking pot with excellent heat retention effect.

Since a flat portion is formed on the upper surface of the heater and the bottom of the pot is brought into close contact with the heater, the heating effect is further improved.

A space is formed around the lower part of the pot where the air-insulated peripheral gap and the air-insulated bottom gap communicate with each other, and the hot air of the heater is further used for heating and keeping heat by using this space. It becomes a cooking pot.

[0024] The air-conditioning electric charge of the entire kitchen can be greatly reduced, and the cooking pot can be called the kitchen revolution.

It can be easily moved and installed to a place where there is an outlet, and handling becomes easy.

Because of the hermetically sealed waterproof structure, it can be washed in water and is excellent in versatility.

Because of the double insulation structure, the cooking pot has excellent safety such as fire prevention and burn prevention.

The heat source uses electricity, and its wiring work is lower in cost than gas work.
