Description

  The present invention relates to a mounting fixing structure for a built-in heating cooker.

  In recent years, in the case of performing hot pots or the like on a table for a customer's seat in a restaurant or the like, from the viewpoint of safety, there are an increasing number of those incorporating a built-in induction heating cooker instead of a gas stove.

  FIG. 5 shows an example of installation of a conventional induction heating cooker. In the induction heating cooker, an induction heating coil 8, a circuit device 9, etc. are arranged below the cooking plate 3 made of ceramic or the like. The main body case 11 houses a cooling fan 10 for cooling the circuit device 9.

  By the way, as an advantage of using the built-in induction heating cooker in the table 1 for the passenger seat, in addition to safety, the cooking plate 3 and the top plate 2 have the same top surface, so that cooking is not performed when cooking is not performed. A plate or the like can be placed on the plate 3 and can also serve as a table.

  As a method for making the upper surface of the cooking plate 3 and the top plate 2 the same surface, the cooking plate 3 and its frame are made larger than the main body case 11 as shown in Patent Document 1 below. A slightly larger digging process than the cooking plate 3 was performed around the slightly larger opening 4 and further around the opening 4. The level difference in the digging process is the same as the thickness of the flange portion formed by the cooking plate 3 and its frame.

  The heating cooker body 17 is fixed by attaching the flange portion to the stepped portion around the opening 4 of the top plate 2 and adhering the periphery with a silicon coating agent or the like.

  As described above, the top plate 2 is not only provided with the opening 4 but also needs to be digged slightly larger than the cooking plate 3 around the opening 4, and the depth of the digging is increased. Must be precisely adjusted so that the thickness of the flange is the same as the thickness of the flange.

Japanese Utility Model Sho 55-114194 microfilm

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a built-in heating cooker that can reduce the processing man-hour of the top plate.

  In order to achieve the above-described object, the built-in heating cooker according to the present invention has a substantially L-shaped flange having a through-hole in a single plane on the side surface of the heating cooker body case located below the lower surface of the heating plate. The flange portion is fixed integrally with the other flat surface of the portion as the mounting surface of the side surface, and at least the one flat surface and the lower surface of the top plate are closely fixedly engaged with each other by screwing through the through hole. Features.

  Moreover, the flange part which fixes a heating cooker main body is made into a member different from a heating cooker main body, and provided the elongate hole in the said other plane engaged with a heating cooker main body.

  Further, the mounting surface which is the other flat surface of the flange portion is provided with a long hole, and the side surface of the case is provided with a screw hole at a position corresponding to the long hole. To do.

  According to the built-in heating cooker according to the present invention, the following effects can be obtained.

(A) The processing of the top plate, together with the opening of the main body, it is not necessary to dig a little larger than the cooking plate around the opening, it is only necessary to open a slightly larger opening than the cooking plate, as in the past In addition, it is not necessary to strictly adjust the depth of cut of the opening, and the man-hour for processing the top plate can be greatly reduced.

(A) According to the second embodiment, the cooking plate and the top surface of the top plate can be easily made the same even in the top plate having different thicknesses.

Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the accompanying drawings.
In addition, although it is set as the induction heating cooking appliance in a present Example, the heating source may be a radiant heater which provided the nichrome wire under the cooking plate.

FIG. 1 is an example of an installation form of an induction heating cooker incorporated in a table 1 for a passenger seat. An opening 4 that is slightly larger than the cooking plate 3 is provided in the top plate 2, and the induction heating cooker body 17 One of the inventions is fitted into the opening 4 from below. A substantially L-shaped flange portion 5 is formed on the side surface of the heating cooker body 17, and a screw through hole 6 is provided on one flat surface 5 a of the flange portion 5, and the lower surface 2 a of the top plate 2 extends from the flat surface 5 a. The heating cooker body 17 is fixed by tightly fixing the flat surface 5a and the lower surface 2a with a wood screw 7 through the screw through hole 6.
The flat surface 5a of the flange portion 5 is provided at a position lower than the top surface 3a of the cooking plate 3 by the thickness of the top plate 2, and is fixed with a wood screw 7 so that the top surface 3a of the cooking plate 3 and the audience seat The top surface 2b of the top plate 2 of the table 1 can be made substantially flush. Further, the gap between the cooking plate 3 and the opening 4 may be closed with a silicon-based adhesive.

FIG. 2 is a cross-sectional view of the built-in induction heating cooker according to the present invention. In the lower part of the cooking plate 3, an induction heating coil 8, a circuit device 9, etc. are arranged, and cooling for cooling the circuit device 9 is performed. A case 11 that houses the fan 10 is provided.
A flange portion 5 is engaged with a side surface of the case 11, and a screw through hole 6 is provided on a flat surface 5 a of the flange portion 5.
The height A of the upper surface 3 a of the cooking plate 3 and the flat surface 5 a of the flange portion 5 is the same as the thickness of the top plate 2.

FIG. 3 is a perspective view of the second embodiment, and FIG. 4 is a cross-sectional view of a built-in induction heating cooker in which the flange portion 5 according to the second embodiment is attached to the main body case 11.
A long hole 12 is provided on the case mounting surface, which is the other flat surface 5 b of the flange portion 5, and a screw hole 13 is provided on the side surface of the case 11 at a position corresponding to the long hole 12.
By inserting a screw 14 into the elongated hole 12 and changing the fixing position, it becomes possible to adjust the height A of the upper surface 3a of the cooking plate 3 and the one plane 5a of the flange portion 5.
It is desirable to prevent loosening by using a spring washer 15 and a washer 16 for the screw 14 to be used.

  In this way, the flange portion 5 is provided on the side surface of the heating cooker body 17 positioned below the lower surface of the cooking plate 3, the screw through hole 6 is provided on one plane 5 a of the flange portion 5, and the top of the flange portion 5 is By fixing the heating cooker main body 17 to the lower surface 2a of the plate 2 with the wood screw 7, it is possible to significantly reduce the number of steps for the top plate processing without requiring a step processing on the top plate 2 as in the prior art.
