Description

  The present invention relates to a heating cooker provided with a heating plate.

  The heating cooker provided with a heating plate is provided with the heating plate which consists of steel materials (iron plate), and the heating source which heats a heating plate. A hard steel material is used as the heating plate on which the food to be heated is placed on the surface so that the surface is not damaged even if a metal cooking tool is used. Such a heating cooker uses a gas burner or an electric heater as a heating source, and various forms are available depending on the object to be cooked and the cooking method, such as a griddle, a hot plate, an iron plate cooker, a dumpling cooker, a Genghis khan pan It is known (refer the following patent document 1).

  In such a heating cooker, it is difficult to uniformly heat the entire surface of the heating plate with a heating source, so there is a problem that the surface temperature of the heating plate becomes uneven. This problem is remarkable particularly in a commercial heating cooker having a large area of a heating plate, and in the case where many cooking objects are arranged at the same time on the surface of the heating plate, etc. Variations occur, causing the problem of not being able to finish many objects at the same time.

  The solution to this is to increase the thermal conductivity of the heating plate. Since thick steel materials do not have high thermal conductivity, it is possible to equalize the overall heat transfer by joining a plate such as an aluminum material having high thermal conductivity to the steel materials. However, in a heating cooker such as a griddle, the peripheral portion of the heating plate is fixed to a side wall, a casing, or the like, and when an aluminum material or the like is joined to a steel material, a side structure such as a side wall The problem arises that the part and the peripheral edge of the heating plate can not be joined by welding.

  The present invention takes an example of the problem to address such a problem. That is, it is an object of the present invention to provide a heating cooker having a heating plate with good thermal conductivity, and to be able to weld the peripheral portion of the heating plate to the side structure.

In order to achieve such an object, the heating cooker according to the present invention at least has the following configuration.
A heating cooker comprising a heating plate having a cooking surface on which an object to be cooked is placed, and a heating source for heating the heating plate, wherein the heating plate comprises a steel layer and high thermal conductivity joined to the steel layer. A weldable portion having a material layer, the front surface and the back surface both being the steel material layer is provided at the peripheral portion of the heating plate, and the heating plate and the side structure portion are provided via the weldable portion Are welded, the high thermal conductivity material layer is pressure bonded to the back surface side of the steel material layer, and the high thermal conductivity material layer is not crimped to the peripheral portion of the heating plate. A heating cooker characterized in that the weldable portion is provided .

  The present invention having such features can provide a heating cooker having a heat conductive plate having good thermal conductivity, and further, welding the peripheral portion of the heat plate to a side structure such as a side wall it can.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG.1 and FIG.2 has shown the whole structure of the heating cooker which concerns on one Embodiment of this invention. The heating cooker 1 includes a heating plate 2 having a cooking surface 2A on which an object to be cooked is placed, and a heating source 3 for heating the heating plate 2. Furthermore, the heating cooker 1 is provided with the side structure part 10 to which the peripheral part of the heating board 2 is attached. The side structure 10 is formed of a side wall 4 surrounding the heating plate 2 and a housing 5 surrounding the heating source 2. The housing 5 is provided with operation units 5A and 5B for operating the heat source 3 on the front surface thereof.

  The heating source 3 here employs a gas burner that generates a combustion flame by gas supply, an electric heater that generates Joule heat by electricity supply, an induction heating source (IH heater) that inductively heats a heating plate by electricity supply, or the like. be able to.

In the heating plate 2, the high thermal conductive material layer 21 is joined to the steel material layer 20. In the first embodiment shown in FIG. 3A, in the heating plate 2, the high thermal conductive material layer 21 is crimped and bonded to the back surface side of the steel material layer 20. In the second embodiment shown in FIG. 3B, the heating plate 2 has a structure in which the high thermal conductive material layer 21 is sandwiched between the steel material layer 20 on the surface side and the steel material layer 22 on the back surface side.

  As the high thermal conductive material layer 21 here, a material with high thermal conductivity such as aluminum or an aluminum alloy can be used. The pressure bonding of the high thermal conductive material layer 21 to the steel material layer 20 can be performed using a known bonding method such as explosive pressure welding. The material of the high thermal conductive material layer 21 is not limited to aluminum or an aluminum alloy, and copper, tungsten, or an alloy thereof can be used. Also, a bonding method such as explosive pressure welding can be applied to the pressure bonding of the high thermal conductive material layer 21 to the steel material layer 22.
