Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking device temperature sensor for sensing the temperature of an object to be heated by contacting the object with a cooking utensil used at home or the like. The present invention relates to the shape of a welded portion when welding to a fixing plate that is fixed to an instrument.

[0002]

2. Description of the Related Art A conventional temperature sensor 1 for a cooking device is shown in FIGS.
This will be described with reference to FIG.

The temperature sensor for the cooking device is a temperature sensitive body 2.
The heat-sensitive part 5 that comes into contact with the object to be heated 4 placed on the battery 3
The sheet metal 6 for holding the heat-sensitive portion 5 is welded to the fixed plate 7, and the sheet metal 6 is processed into a substantially left-right symmetrical shape with respect to the center line 8 and is bent at the bent portion 9 of the center line 8. 2 on the opposite end 11 to the end face 10 which is
The sheet metal A12 and the sheet metal B13 are configured to be bent, and the sheet metal B13 is bent to hold another sheet metal A12 to form the caulking portion 14, and the end surface 10 and the caulking portion 14 are attached to the fixing plate 7. When a gap 15 is formed between each bent portion and the fixed plate 7 when they are brought into contact with each other, the bent portion 9 and the crimped portion 14 are the two sheets, that is, the sheet metal A12 and the sheet metal B13. Was welded to the fixing plate 7.

[0004]

However, in the structure of the conventional example as described above, the sheet metal 6 processed into a substantially symmetrical shape with respect to the center line 8 of the sheet metal 6 is bent at the bent portion 9 of the center line 8, and the center line is bent. End portion 1 on the opposite side to end surface 10 on the 8 side
The sheet metal A12 of the two sheet metal A12 and the sheet metal B13 of the sheet metal B13 which are folded to hold the other sheet metal A12 and the sheet metal A12 of the sheet metal 6 which is the two sheets of the folded portion 9 and The portion of the sheet metal B13 is fixed to the fixed plate 7 by the sheet metal A.
Since 12 and the sheet metal B13 were melted together and welded to the fixed plate 7, the welding load becomes large, so that the electric current value becomes large in the case of electric welding and a hole may be formed if the welding conditions are a little wrong. However, there was a problem that welding could not be performed sufficiently. Further, since the end face 10 and the caulked portion 14 are both bent, a gap 15 is formed between the end face 10 and the caulking portion 14 with the fixing plate 7 at the bent portion. In this case, since the argon gas does not fill the gap 15 and is welded without being replaced by the remaining air, the welded portion is oxidized by the remaining air and the fixing plates of the end faces 10 and 11 are fixed. There was a problem that welding with 7 could not be performed reliably.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to construct a welded portion shape capable of reliably welding to a fixing plate for fixing a temperature sensor for a cooking device to a cooking utensil.

[0006]

In order to achieve the above object, the temperature sensor for a cooker according to the present invention is constructed by bending a sheet metal processed into a substantially left-right symmetric shape at the center line at the bent portion of the center line, Make a caulking part by bending one of the two metal plates at the end opposite to the line-side end face to hold the other metal plate, and make a bent part and the caulked part 2 From the same direction, the sheet metal is a sheet metal in the same direction at the cutout hole and the cutout portion,
This is provided with a structure in which the end surface of the cut-out sheet metal A is melted and fixed to the fixing plate.

[0007]

The temperature sensor for a cooker according to the present invention is a sheet metal machined in a substantially symmetrical shape with respect to the center line, bent at the bent portion of the center line, and two pieces are provided at the end opposite to the end face on the center line side. Make a caulking part by bending one of the sheet metals of the above and holding the other sheet metal, and cut the sheet metal which is the bent part and the caulking part from the same direction into the notch hole and the notch. As one sheet metal B in the same direction in the section, the end face of the notched sheet metal A is melted and fixed to the fixing plate,
Since there is no gap formed between the end surface of the metal plate A that abuts against the fixed plate and the fixed plate, there is no air remaining when welding the two, and therefore the entire welded portion is filled with an inert gas such as argon gas. Welding is easy because it is wrapped.
Further, since there is only one welded portion as the sheet metal A, the welding load can be small, and therefore the welding can be easily performed without being largely influenced by the welding conditions.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. It should be noted that parts having the same functions as those of the conventional example are denoted by the same reference numerals and the description thereof will be omitted.

In FIGS. 1 to 4, reference numeral 16 denotes an end surface 1 which is a sheet metal B13 only when a sheet metal 6 processed into a substantially symmetrical shape at a center line 8 is bent at a bending portion 9 of the center line 8.
A notch hole formed on the 0 side, and 17 is two sheet metals A1 at the end 11 on the opposite side to the end surface 10 on the center line 8 side.
2 and the sheet metal B13 of the sheet metal B13 is a notch portion formed in the end portion 11 when the caulking portion 14 is formed by bending the sheet metal B13 and holding the other sheet metal A12.
The cutout hole 16 and the cutout portion 17 are formed of sheet metal A12.
Only the metal plate A12 is brought into contact with the fixed plate 7 and the fixed plate 7 and the metal plate B13 are welded to each other.

In the above structure, the temperature sensor 1 for the cooker
Is a sheet metal 6 processed into a substantially left-right symmetrical shape with respect to the center line 8 at the bent portion 9 of the center line 8, and the end surface 1 on the side of the center line 8 is bent.
One of the two sheet metals at the end 11 on the opposite side to 0 is bent to hold the other sheet metal 6 to form the crimp portion 14, and the bent portion 9 and the crimp portion 14 are formed. 2 sheet metal 6 is cut out from the same direction
6 and the notch 17 form one sheet metal A12 in the same direction, and the end surface of the sheet metal A12 formed by each notch is melted and fixed to the fixed plate 7, so that the end surface 10 of the sheet metal A12 that abuts the fixed plate 7 Since a gap 15 is not formed between the fixing plate 7 and the fixing plate 7, there is no air remaining when welding the two, and the entire welded portion is wrapped in an inert gas such as argon gas, which facilitates welding. Can be done. Also,
Since there is only one welded portion as the sheet metal B13, the welding load can be small, and therefore the welding can be easily performed without being greatly affected by the welding conditions.

[0011]

As described above, the following effects can be obtained with the temperature sensor for a cooker according to the present invention.

(1) A sheet metal processed into a substantially left-right symmetrical shape with respect to the center line is bent at the bending portion of the center line, and one of the two sheet metals at the end opposite to the end face on the center line side is bent. Make a caulking part by folding and holding another sheet metal, and cut out the two sheet metal parts of the bending part and the caulking part from the same direction to cut one sheet metal A in the same direction.
As the end face of the notched sheet metal A is melted and fixed to the fixed plate, there is no gap between the end face of the sheet metal A abutting the fixed plate and the fixed plate. Since there is no residual air, the welded part is entirely wrapped in an inert gas such as argon gas, so that welding can be performed easily.

(2) Since there is only one welded portion as the sheet metal A, the welding load can be small, and therefore the welding can be easily performed without being greatly affected by the welding conditions.
