Description

  The present invention is most suitable for cooking pots for business use or household use, especially cooking pots used for cooking almost all day, for example, soup pots (deep pots) that require a long period of time to be used in restaurants. The present invention relates to a heat collecting structure of a cooking pan.

  In conventional cooking pans, the bottom of the pan is intensively heated by a gas burner, which tends to cause cooking spots due to convection spots of the liquid in the pan and scorching on the inner surface of the pan, and most of the gas heated by the gas burner It escapes from the bottom of the pan bottom to the side of the pan shell, or an external flame of the heating flame escapes to the side of the pan shell, and this thermal escape and flame escape cause a significant decrease in thermal efficiency.

  The present invention effectively suppresses heat escape and flame escape of the gas burner that heats the pan bottom, achieves a significant improvement in thermal efficiency, eliminates cooking spots, and further shortens cooking time. It provides a heat collection structure for pots.

  The pan for cooking according to the present invention includes a heat collecting plate attached in an annular shape along the outer peripheral surface of the lower end of the pan body rising from the bottom of the pan, and the heat collecting plate is formed by projecting the lower end edge below the bottom of the pan. A heating space by a gas burner surrounded by the heat collecting rim is defined immediately below the pan bottom, and the pan bottom is uniformly heated by the high-temperature gas in the heating space. In this way, heat conduction to the peripheral surface of the lower end of the pan body is caused uniformly.

  Preferably, a gap for introducing a heated gas that communicates with the heating space is formed between an outer peripheral surface of the lower end of the pan body and an inner peripheral surface of the heat collecting plate, and in addition to heating by heat conduction by the heat collecting rim, The pan body bottom peripheral surface is configured to be uniformly heated with a high-temperature heating gas.

  According to the present invention, the entire surface of the bottom surface of the pan bottom can be uniformly heated by the heated gas in the heating space surrounded by the heat collecting rim of the heat collecting plate, and at the same time, the heat collecting rim is heated, The peripheral surface of the lower end of the pan body can be uniformly heated by heat conduction from the pan.

  In addition, the heating gas introduced into the heating gas introduction gap at the peripheral edge of the heating space can promote uniform heating of the outer peripheral surface of the lower end of the pan body, effectively preventing the heat escape and flame escape of the gas burner, Thermal efficiency can be improved.

  ADVANTAGE OF THE INVENTION According to this invention, the convection of the liquid in a pot can be induced actively and cooking spots and the local burning of a pot bottom inner surface can be prevented effectively.

The best mode for carrying out the present invention will be described below with reference to FIGS.
As is well known, the cooking pan has a pan body 2 that rises from a pan bottom 1 heated by a ring-shaped gas burner 4, and has a pan lid 5 that closes the pan mouth 3 on the top surface of the pan body 2.

  The present invention is particularly effective for a cooking pan having a long pan (2) height (depth), that is, a pan having a cylindrical pan (2) having a height equal to or greater than the diameter of the pan bottom (1).

  In a deep pan, uniform convection in the liquid in the pan (cooked food) hardly occurs, and cooking spots are generated. In addition, local overheating occurs in a portion of the burner 4 that comes into contact with the flame, and local burning of the pan bottom 1 becomes apparent. Moreover, since the depth is deep, it is difficult to avoid deterioration of thermal efficiency.

  The present invention is effective when applied to such a deep pan. Hereinafter, the deep pan 6 will be illustrated and a specific example of the present invention will be described.

  In the deep pan 6 in which the pan body 2 is raised from the periphery of the pan bottom 1 heated by the ring-shaped gas burner 4, along the outer peripheral surface of the pan body 2, that is, the outer peripheral surface close to the pan bottom 1 of the pan body 2. The heat collecting plate 7 is attached in an annular shape.

  The heat collecting plate 7 is made of metal, and is made of metal such as aluminum or copper as an appropriate material. The heat collecting plate 7 has a lower end edge projecting annularly downward from the lower surface of the pan bottom 1 to form a heat collecting rim 8.

  The heat collecting rim 8 surrounds the pan bottom 1 in an annular shape, and by forming the annular heat collecting rim 8, a heat collecting space 9 is defined immediately below the pan bottom 1 inside the heat collecting rim 8. That is, facing the lower surface of the pan bottom 1, a heat collecting space 9 is defined by the pan bottom 1 and the heat collecting rim 8.

  Further, an annular heating gas introduction gap 10 that communicates with the heating space 9 is formed between the outer peripheral surface of the lower end of the pan body 2 and the inner peripheral surface of the heat collecting plate 7.

  As a specific example, a metal strip 7 ′ shown in FIGS. 7 and 8 is wound around the outer peripheral surface of the lower end of the pan body 2 to form an annular heat collecting plate 7, and the upper edge of the heat collecting plate 7. Is attached to the outer peripheral surface of the pan body 2 by welding 12.

  The inner peripheral surface of the heat collecting plate 7 and the outer peripheral surface of the lower end of the pan drum 2 are merely free contact interfaces except for the weld 12 part, or form a slight annular gap.

  The contact interface or the annular gap allows the introduction of the heated gas in the heating space 9, and both are referred to as a heated gas introduction gap 10.

  That is, the bottom surface of the pan 1 is shielded from heat escape and flame escape by a heat collecting rim 8 that surrounds it in a ring shape, and a hot gas pool is formed in the heating space 9, and further the heat collecting rim 8 itself is heated. To do.

  Therefore, the lower end peripheral surface of the pan body 2 is uniformly heated by heat conduction through the heat collecting rim 8 while uniformly heating the lower surface of the pan bottom 1 with the high-temperature heating gas in the heating space 9. The heating gas in the heating space 9 is introduced into the heating gas introduction gap 10 communicating with the heating gas 9 at the periphery of the heating space 9 to uniformly heat the outer peripheral surface of the lower end of the pan body 2.

  As a means for accelerating the flow of the heated gas introduced into the heated gas introduction gap 10 and effectively inducing the heated state, as shown in FIGS. A heated gas discharge portion 11 that discharges the heated gas introduced into the gap 10 to the outside can be provided at the upper edge portion.

  The heated gas trapped in the heating space 9 is introduced into the heated gas introduction gap 10 and is discharged to the outside, mainly along the outer peripheral surface of the pan drum 2 through the heated gas discharge portion 11, for introducing the heated gas. The introduction and flow of the heated gas into the gap 10 is promoted.

  As a specific example, as shown in FIG. 7, a plurality of heat radiation ports 11 a are provided at the upper edge of the metal strip 7 ′, and the metal strip 7 ′ is wound around the lower peripheral surface of the pan barrel 2. And the annular heat collecting plate 7 which has the heating gas discharge | release part 11 (radiation port 11a) is formed by welding 12 the strip 7 'upper end surface.

  Alternatively, as shown in FIG. 8, a heat radiation notch 11b is provided in the upper side of the metal strip 7 ', and this metal strip 7' is wound around the outer peripheral surface of the lower end of the pan body 2, The annular heat collecting plate 7 having the heated gas discharge part 11 (radiation notch 11b) is formed by welding 12 at the upper end surface.

  Alternatively, the metal strip 7 ′ is wound around the outer peripheral surface of the lower end of the pan body 2 without providing the heat radiating port 11 a and the heat radiating notch 11 b, and the upper end surface of the strip 7 ′ is intermittently provided on the outer peripheral surface of the pan body 2. By carrying out welding 12 to each other or by spot welding 12, a gap or a free contact surface between the welding 12 parts can be used as the heated gas discharge part 11.

  FIG. 4 shows a pan mounting table 13 for the cooking pan. The pan mounting table 13 has an accommodating portion 14 for the gas burner 4, and a window 16 facing the pan bottom 1 on the top plate 15 of the burner accommodating portion 14. And the pan bottom 1 is heated through the window 16, and the virtues 17 that support the pan bottom 1 are provided on the top surface of the top plate 15 of the pan mount 13.

  On the other hand, notches 18 for receiving the virtues 17 are provided at the lower end edge of the heat collecting rim 8 at intervals in the circumferential direction, and when the pan bottom 1 is supported on the virtues 17 of the pan mount 13, the notches 18 of the heat collecting rim 8 are provided.
