Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cooking pot used for cooking food.

[0002]

[Prior art]

 As a heater used when cooking food in a pan, in recent years, electromagnetic heaters that heat the pan itself by electromagnetic induction, halogen heaters that use a halogen heater as a heat source, etc., have used gas. It has less problems of fire, air pollution, heat loss, etc. compared to other heaters, and is rapidly spreading as a safe, clean and highly efficient heater.

In these heaters, heating is performed locally as compared with those using a gas flame as a heat source. For example, in the case of an electromagnetic heater, only the portion of the pot bottom where the magnetic force lines act is sharp and local. There is a problem that heat is generated in the pan and heat is not transmitted to the other parts. Therefore, it was difficult to obtain a uniform temperature distribution in the entire pan.

[0004]

[Problems to be solved by the device]

 An object of the present invention is to provide a heat-efficient cooking pot that can quickly and uniformly transfer and distribute heat to the entire pot even if it is locally heated by an electromagnetic heater or a halogen heater. .

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the pan of the present invention has a plurality of heat pipes for transmitting heat from the heat generating part to the non-heat generating part from the heat generating part corresponding to the heater to the non-heat generating part outside thereof. It is characterized by being installed.

The plurality of heat pipes include an inner heat pipe group extending from the heat generating portion to the non-heat generating portion, one end of the heat pipe is located between adjacent heat pipes of the inner heat pipe group, and the other end of the inner heat pipe group. It may be arranged separately to the outer heat pipe group extending further outward.

[0007]

[Action]

 The heat from the heat generating part is quickly transferred to the non-heat generating part on the outside by the heat pipe, so that even if the pot is locally heated, the entire temperature distribution quickly becomes uniform.

[0008]

【Example】

 Embodiments of the present invention will now be described in detail with reference to the drawings. FIGS. 1 and 2 show an electromagnetic heater pan as an example of the cooking pan of the present invention. The pans 2 are electromagnetic heaters for heating the pan 1 by electromagnetic induction from the magnetic coils.

The pan 1 is provided with a magnetic layer 6 as an electromagnetic induction heat generator on the outer surface of the bottom 5a of the pan body 5 made of aluminum, so that heat is generated in the part corresponding to the electromagnetic coil of the electromagnetic heater 2. In order to transfer the heat generated in the exothermic part 3 to the non-exothermic part 4 from the exothermic part 3 to the non-exothermic part 4 on the outside of the pan 1, the pan 3 is formed. A plurality of heat pipes 8 are radially embedded. These heat pipes 8 have a radial inner heat pipe 8 a group arranged so that one end is located on the outer peripheral portion of the heat generating part 3 and the other end is located on the non-heating part 4, and one end of the non-heating part 4 is arranged. Is located between the adjacent heat pipes 8a, 8a of the inner heat pipe 8a group, and is divided into a radial outer heat pipe group 8b group arranged so that the other end is located outside the inner heat pipe group 8a. ing.

The heat pipe 8 may have an arbitrary cross-sectional shape, but a flat cross-sectional shape is used to prevent the thickness of the pot 1 from becoming too large due to the embedding thereof. Desirably, when the side wall of the pot 1 is curved, a flexible heat pipe may be used so that it can be embedded along the shape. Further, the inner heat pipe 8a and the outer heat pipe 8b may have the same length, but one of them may be longer than the other.

The magnetic layer 6 is formed by melting a magnetic material such as iron at a high temperature of 1500 ° C. or higher (eg, about 1000 ° C.) and jetting it at a high pressure. The thickness of the magnetic layer 6 is preferably about 0.5 mm.

Protrusions for placing the bottom of the pan on the electromagnetic heater 2 while keeping a constant space are formed on the part of the pan main body 5 where the magnetic material layer is not formed on the outer periphery of the pan as needed. You can It is desirable that three protrusions are provided at equal intervals in the portion where the magnetic layer is not formed, but they can also be formed as a ring-shaped wall that surrounds the magnetic layer 6, and the height of the protrusion can be increased by electromagnetic heating. It is set to an appropriate height within a space width (for example, about 9 mm) where the magnetic force lines from the container 2 can sufficiently reach the magnetic layer 6.

When the pot 1 having the above-mentioned configuration is placed on the electromagnetic heater 2 and the electromagnetic coil is energized, the magnetic lines of force from the electromagnetic coil act on the magnetic layer 6, and the magnetic layer 6 is induced by electromagnetic induction. Heats up. The heat generated from the magnetic layer 6 is transferred to the non-heat generating part 4 by the inner heat pipe 8a to heat the non-heat generating part 4, and then transferred to the outer part of the non-heat generating part 4 by the outer heat pipe 8b. It For this reason, heat is quickly transferred to the entire pan, resulting in a uniform temperature distribution throughout the pan.

Further, the heat pipes 8a and 8b are arranged in an inner and outer double, and the respective heat pipes 8b of the outer heat pipe 8b group are arranged between the adjacent heat pipes 8a and 8a in the inner heat pipe 8a group. As a result, compared to the case where a long heat pipe having a length from the inner end of the inner heat pipe 8a to the outer end of the outer heat pipe 8b is simply provided, a portion between adjacent heat pipes becomes a blind spot for heat transfer. The temperature distribution is very good because it is not present.

In addition, in order not to provide a heat pipe around the entire circumference of the pan 1 and to omit embedding of the heat pipe for a part of the pan 1, the portion where the heat pipe is omitted is to avoid the roasted meat or the like. It can also be used as a heat insulation part.

FIG. 3 and FIG. 4 show a second embodiment of the present invention. The pan 11 of this embodiment is such that the heat from the bottom of the pan extends from the heating part 13 at the bottom of the pan to the side wall of the non-heating part 14. A large number of heat transfer ribs 17 for transmitting the heat to the side wall are radially formed, and a heat pipe 18 is embedded in each rib 17. In this case, the heat pipe 18 is arranged along one circumference without being divided into a plurality of inner and outer pipe groups as in the first embodiment.

5 to 7 show a third embodiment of the present invention. In the first embodiment, the heat pipe is embedded in the pan, whereas in the third embodiment, the heat is used. The pipe is fixed to the outer surface of the pot by caulking. That is, a concave portion 22 such as a depression or groove is formed at a predetermined position of the pan 21, and the inner heat pipe 23a and the outer heat pipe 23b of the heat pipe 23 are fitted into the concave portion 22 and the caulked portion 24 is fitted with them. It is more fixed. In this case, as shown by a chain line in FIG. 5, a decorative plate 25 such as an iron plate may be provided so as to cover the heat pipe. Even in the structure as in the second embodiment, the heat pipe 18 can be fixed by caulking.

Further, in each of the above-described embodiments, the pot for an electromagnetic heater in which the magnetic layer is provided on the bottom surface of the aluminum pot main body has been described, but it may be an iron pot or a halogen heater or the like. The same can be applied to an aluminum or iron pot used for the.

[0019]

[Effect of device]

 As described above in detail, according to the cooking pan of the present invention, since a plurality of heat pipes are buried from the heat generating portion to the non-heat generating portion, the heat from the heat generating portion is not absorbed by each heat pipe. The entire pot can be heated to a uniform temperature distribution. Moreover, the heat storage property of the heat pipe also improves the heat retention after the heating is stopped.
