DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art FIG.
This will be described with reference to FIG.

[0003] The temperature sensor for this cooker is a temperature sensitive element 2.
Part which comes in contact with the object to be heated 4 placed on the body 3
And a sheet metal 6 holding the heat-sensitive portion 5 is welded to the fixing plate 7. The sheet metal 6 is formed by bending a sheet metal 6 processed into a substantially symmetrical shape at the center line 8 at a bent portion 9 of the center line 8. 2 at the end 11 opposite to the end face 10
The sheet metal A12 and the sheet metal B13 are formed, and the sheet metal A12 is bent so as to hold the other sheet metal B13 , thereby forming a caulking portion 14, and the end face 10 and the caulking portion 14 are applied to the fixing plate 7. When the gap 15 is formed between each bent portion and the fixed plate 7 when they are brought into contact with each other, the sheet metal A12 and the sheet metal B13 of the sheet metal 6 which is the two parts of the bent part 9 and the caulking part 14 are formed. Is welded to the fixing plate 7.

[0004]

However, in the configuration of the prior art as described above, the sheet metal 6 processed into a substantially symmetrical shape at 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 formed. End 1 opposite to end face 10 on the 8 side
1 and a sheet metal A12 of a sheet metal 6 which is a sheet metal 6 formed by bending a sheet metal A12 of a sheet metal B13 so as to hold the other sheet metal B13. The part of the sheet metal B13 is attached to the fixing plate 7 by the sheet metal A.
12 and the sheet metal B13 were melted together and welded to the fixed plate 7, so that the welding load was increased, so that in the case of electric welding, the current value was increased and if the welding conditions were slightly wrong, holes would be formed. Therefore, there is a problem that welding cannot be performed sufficiently. Further, since the end face 10 and the caulking portion 14 are both bent, a gap 15 is formed between the bent portion and the fixing plate 7. The welding portion is oxidized by the remaining air because the argon gas is not filled in the gap 15 at the time of welding because the argon gas is not filled in the gap 15 at the time of welding, and the welded portion is oxidized. 7 has a problem that it cannot be reliably welded.

An object of the present invention is to solve such a conventional problem, and it is an object of the present invention to form a welded portion shape which can reliably weld a temperature sensor for a cooking appliance to a fixing plate for fixing the cooking appliance to a cooking appliance.

[0006]

In order to achieve the above object, a temperature sensor for a cooking appliance according to the present invention is provided by bending a sheet metal processed into a substantially symmetrical shape with respect to a center line at a bent portion of the center line. One of the two sheet metals at the end opposite to the end face on the line side is bent to form a caulked portion by holding the other sheet metal, and the bent portion and the caulked portion 2 As a sheet metal in the same direction at the notch hole and the notch part from the same direction,
It has a configuration in which the end face of the cut-out sheet metal A is melted and fixed to a fixed plate.

[0007]

The temperature sensor for a cooker according to the present invention is obtained by bending a sheet metal processed into a substantially symmetrical shape at the center line at a bent portion of the center line, and forming two sheets at opposite ends with respect to the end surface on the center line side. One of the sheet metal is bent to hold the other one of the sheet metal to form a swaged part, and the two parts of the bent part and the swaged part are cut out and cut out from the same direction. As one sheet metal B in the same direction at the part, the end face of the notched sheet metal A was melted and fixed to the fixed plate,
Since there is no gap between the end face of the sheet metal A contacting the fixing plate and the fixing plate, there is no air remaining when welding the two, so that the entire area is welded in an inert gas such as argon gas. It can be easily welded to be wrapped.
Further, since there is only one welded portion as the sheet metal A, the welding load can be reduced, so that 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. Parts having the same functions as those of the conventional example are denoted by the same reference numerals, and description thereof is omitted.

In FIG. 1 to FIG. 4, reference numeral 16 denotes an end face 1 which becomes only the sheet metal B 13 when the sheet metal 6 processed into a substantially symmetrical shape at the center line 8 is bent at the bent portion 9 of the center line 8.
Reference numeral 17 denotes a notch hole formed on the 0 side, and 17 denotes two sheet metals A1 at the end 11 opposite to the end face 10 on the center line 8 side.
2 and a notch formed in the end portion 11 when the caulking portion 14 is formed by bending the sheet metal A12 of the sheet metal B13 so as to hold the other sheet metal B13.
Of the notch hole 16 and the notch portion 17 of the sheet metal A12
Only the sheet metal A12 is brought into contact with the fixed plate 7 and the fixed plate 7 and the sheet metal B13 are welded.

[0010] In the above configuration, the temperature sensor 1 for the cooking device
Is formed by bending a sheet metal 6 processed into a substantially symmetrical shape at the center line 8 at a bent portion 9 of the center line 8, and the end face 1 on the center line 8 side.
The two sheet metals A12 at the end 11 opposite to the sheet metal 0 are bent to hold the other sheet metal B13 , thereby forming a caulked portion 14. The bent portion 9 and the portion 2 of the caulked portion 14 are formed. One sheet metal A12 is formed in the same direction by the notch hole 16 and the notch portion 17 from the same direction.
Since the end face of the sheet metal A12 formed by each notch is melted and fixed to the fixing plate 7, a gap 15 is formed between the end face 10 of the sheet metal A12 abutting on the fixing plate 7 and the fixing plate 7. Since there is no air, there is no air remaining when welding the two parts, so that the entire area is wrapped in an inert gas such as argon gas, so that welding can be easily performed. Further, since there is only one welded portion as the sheet metal B13, the welding load can be reduced, so that the welding can be easily performed without being largely influenced by the welding conditions.

[0011]

As described above, the temperature sensor for a cooking appliance according to the present invention has the following effects.

(1) A sheet metal processed in a substantially symmetrical shape with respect to the center line is bent at a bent portion of the center line, and one of the two sheet metals at an end opposite to the center line side end face is removed. The crimped portion is formed by bending and holding another sheet metal, and the sheet metal, which is the bent portion and the crimped portion, is cut out from the same direction and one sheet metal A is formed in the same direction.
As the end face of the notched sheet metal A is melted and fixed to the fixing plate, no gap is formed between the end surface of the sheet metal A contacting the fixing plate and the fixing plate, so when welding both parts, Since there is no air remaining, the entire weld is wrapped in an inert gas such as argon gas, so that welding can be easily performed.

(2) Since there is only one welded portion as the sheet metal A, the welding load can be small, so that the welding can be easily performed irrespective of the welding conditions.
