Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an electric stove that is embedded in the top plate of a sink.

BACKGROUND ART Conventional electric stoves of this type have a structure as shown in FIGS. 4 and 5. In the figure, reference numeral 1 denotes a top plate made of stainless steel, and a hole is formed in the center of the top plate 1 for mounting a heat generating element (not shown) such as a sheathed heater. 2
is a top plate metal fitting made of stainless steel and formed into a substantially Z-shaped cross section, and the flat surface of this top plate metal fitting 2 is provided with two screw holes 2a into which tapping screws, etc. are screwed, as shown in Fig. 5. . A total of four of these top plate metal fittings 2 are fixed to the lower part of each corner of the top plate 1 by spot welding. 3 is a box-shaped back plate made of galvanized steel plate;
A flange portion 3a is provided on the end face of the flange portion 3a, and the screw hole 2a of the top plate metal fitting 2
A total of eight fixing holes, two corresponding to each corner, are formed in each corner. The back plate 3 and the top plate 1 are fixed to each other with screws 4 via the top plate metal fittings 2. That is, by matching the fixing holes of the back plate 3 with the screw holes 2a of the top plate metal fitting 2 and making screw connections at eight locations, two at each corner, the back plate 3 and the top plate 1 are connected. were combined to form the main body of the stove.

Problems to be Solved by the Invention However, in the conventional configuration described above, when assembling the back plate 3 and the top plate 1, eight screws 4 are required, which increases the assembly man-hours and the direct material cost of the screws. The problem was that the product was bulky and the cost of the product increased.

The present invention was devised to solve these conventional problems, and provides a low-cost drop-in type electric stove that can reduce the number of man-hours required for assembling the back plate and the top plate, as well as the number of screws used. The purpose is to

Means for Solving the Problems In order to solve the above problems, the present invention provides a top plate that holds a heating element, top plate metal fittings fixed to the lower part of each corner of the top plate, and a top plate that holds a heating element. a back plate located below and fixed to the top plate metal fitting with screws, the top plate metal fitting being formed in a substantially Z-shape;
In addition, two or more rising pieces are provided at intervals on the flat surface of this top plate metal fitting, one screw hole is provided into which the screw is screwed, and an external hole is provided at the upper end of the back plate in the space between the rising pieces. The back plate is fixed to the top plate metal fitting by inserting the flange portion formed to protrude toward the top plate and screwing in screws.

Effect According to the above configuration, the flange portion of the back plate is fixed in the horizontal direction by being inserted into the space between the rising pieces provided at two or more places on the top plate metal fitting, and in the vertical direction, at each corner portion. Since the back plate is fixed to the top plate metal fittings by screwing in only one screw, that is, a total of four screws, sufficient strength can be obtained, and the number of screws used is less than conventional ones. This makes it possible to provide a low-cost electric stove.

Embodiment Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 3.

In the figure, reference numeral 11 denotes a top plate made of stainless steel, and in the center of this top plate 11 is a hole 11 for mounting a heat generating element (not shown) such as a sheathed heater.
It forms a. Reference numeral 12 denotes a top plate metal fitting made of stainless steel and having a substantially Z-shaped cross section.
In the plane part to which the back plate 13 of No. 2 is fastened with screws, one screw hole 12a into which a screw is screwed is provided, and two rising pieces 12b and 12c are provided at intervals. A total of four top plate metal fittings 12 are fixed to the bottom of each corner of the top plate 1 by spot welding.

Reference numeral 13 denotes a box-shaped back plate made of a galvanized steel plate, and the upper end of this back plate 13 is provided with a flange portion 13a that projects outward. A total of four fixing holes 13b are formed in each corner, corresponding to the screw holes 12a provided in the screw holes 12a. The back plate 13 and the top plate 11 are connected to the top plate metal fittings 1.
2 and fixed with screws 14. That is, the fixing holes 13b of the back plate 13 and the top plate metal fittings 12
The back plate 13 and the top plate 1 are integrated to form the stove body by making screw connections at four locations, one at each corner, in correspondence with the screw holes 12a.

In the above configuration, the functions of the rising pieces 12b and 12c of the top plate metal fitting 12 will be explained. Top plate metal fittings 1
The top plate 11 and the back plate 13 to which the screws 2 are fixed are connected with a total of four screws 14, one at each corner. In this state, one rising piece 12b is in contact with the outer end surface of the flange portion 13a of the back plate 13, and the other rising piece 12c is in contact with the outer end surface of the flange portion 13a of the back plate 13.
The flange portion 13a comes into contact with the inner bent portion of the flange portion 13a, that is, the bent root portion of the flange portion 13a, so that the flange portion 13a is sandwiched between the two rising pieces 12b and 12c. As a result, screw fixing hole 1
The flange part 13a of the part where 3b is removed will be fixed in the horizontal direction, and in the vertical direction,
Since it is fixed with only one screw 14 at each corner, that is, a total of four screws 14, sufficient strength can be obtained.

Effects of the Invention As is clear from the above explanation, according to the present invention, two or more rising pieces are provided at intervals on the flat surface of the top plate metal fitting, and the upper end of the back plate is attached to the upper end of the back plate at the interval between the rising pieces. Since the flange part that is formed to protrude in the direction is inserted, even if the number of screw fixing points is reduced, the horizontal movement of the flange part of the back plate can be reliably controlled, and as a result,
The number of fixing screws can be halved from 8 to 4, thereby reducing direct material costs for screws and assembly man-hours, making it possible to provide a drop-in electric stove at a low cost. It is.
