Accordingly, the cooking pot can prevent fires and burns because of its double heat-insulation structure, and the cooking pot excellent in the heating efficiency, safety and heat-retaining property can be provided. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a commercial cooking pan used in a ramen shop or the like.

Traditionally, kitchens in the restaurant industry are narrow, hot and humid, and there are dangers of burns and fires, and the working environment has been extremely harsh.
In addition, the size pan used frequently in ramen shops, etc., was manually adjusted by the cook with a gas stove, so the heat efficiency was extremely low, and the heat insulation of the pan itself was also low.
In addition, there was a cooking pot that improves heat efficiency by attaching a removable heater inside the pot and directly heating the water in the pot. (For example, see Patent Document 1)
JP 2004-57770 A

However, manual cooking with this conventional gas stove is inefficient in heat and requires the cook to constantly adjust the cooking time.
In addition, the heater that attaches a removable heater to the inside of the pan and heats the water directly in the pan was excellent in thermal efficiency, but because the heater was exposed inside, cooking of soup ingredients, otamas, etc. It was bad because the device was caught by the heater and was easy to use.

  Therefore, in order to solve the above problems, the present invention provides an inner pot made of a small-diameter bottomed cylindrical body inside the outer pot of the bottomed cylindrical body, and forms a vacuum layer between the outer pot and the inner pot. A sheathed heater is provided on the bottom of the inner pot.

An inner pot made of a small-diameter bottomed cylindrical body is provided inside the outer pot of the bottomed cylindrical body, a vacuum layer is formed between the outer pot and the inner pot, and the inner pot forms a convex portion above the bottom. A sheathed heater is attached to the bottom surface of the inner pot of the convex portion by welding, and a temperature sensor for controlling the sheathed heater is provided on the bottom surface of the substantially central portion of the convex portion. It is composed of materials.

As described above, according to the present invention, it is possible to provide a cooking pot that is excellent in heating efficiency, has good heat retention, and is easy to use.
In addition, the double heat insulation structure is extremely safe because it can prevent fires and burns.

  Next, an embodiment of the present invention will be described with reference to the drawings.

  No. 1 is a small pan that is often used in ramen shops and canteens and is sometimes called a ramen pan. An inner pot 3 (about diameter 490 mm × height 550 mm) smaller in diameter than the outer pot 2 is formed in a bottomed cylindrical shape, and a space 4 is provided between the outer pot 2 and the inner pot 3.

  The bottom surface 5 of the inner pot 3 is formed with a convex portion 6 in a conical shape, and a flat sheathed heater 7 having a flat shape of about 5 kW is wound around the bottom surface of the concave portion 6 and attached to the bottom surface by welding.

  A temperature sensor 8 comprising a thermistor sensor or the like is provided at the center of the bottom plate 5 and at the center of the convex portion 6, and the temperature in the inner pot 3 is indirectly measured for ON / OFF control of the sheathed heater 7. The heating control of the sheathed heater 7 is performed.

  The terminal of the sheathed heater 7 and the terminal of the temperature sensor 8 are drawn out of the pan 1 from the outlet 9 provided in the outer pan 2 and connected to the control device 10 and the power outlet 11.

  The upper part of the outer pot 2 and the inner pot 3 is connected by welding, and the outlet 9 is also sealed with a resin material or the like, and the space between the outer pot 2 and the inner pot 3 is evacuated to make an inner pot. 3 to prevent the heat from radiating from 3.

12 is a lid provided with a handle 13 at the center, and the inside is formed in a double vacuum structure to prevent heat from being dissipated from the lid 12.
In this embodiment, the outer pot 2 and the inner pot 3 are made of stainless steel, but the same effect can be obtained even if copper or molybdenum steel is used.

  Reference numeral 14 denotes an operation switch attached to the side surface of the pan 1 and the like, which sends a signal to the control device 10 when pressed, and operates the sheathed heater 7 via the relay 15.

  To explain the operation, about 100 liters of water enters the pot 1, the energization of the sheathed heater 7 starts when the operation switch 14 is pressed, the water boils over about 2 hours, and then set by the temperature control switch 16 The control device 10 controls the energization of the sheathed heater 7 so as to maintain the predetermined temperature, and is mainly used for a long time to make a large amount of ramen soup, and uses a gas stove Compared to this, it is possible to provide a cooking pot that is superior in heating efficiency, has good heat retention, and is easy to use.

In addition, since it has a double heat insulation structure, it has high heat retention and is extremely safe because it can prevent fires and burns.
Moreover, since the bottom face of the inner pot 3 has the cone-shaped convex part 6, natural convection in the pot 1 can be promoted, temperature unevenness in the pot 1 can be prevented, and heating can be performed relatively uniformly. .

  In addition, since the inner surface of the inner pot 3 is smooth, a cooking utensil that is easy to use is provided without any cooking utensils being caught or internal materials being caught in the pot during cooking. Is.
