いた。Conventional configurations and their problems Conventionally, thermocouples and thermistors have been used in this type of temperature sensor, and in general, the mounting strength of the tip of the thermocouple,
The connection strength of the thermistor electrode L lead wire is not very strong. Therefore, if the lead wire of the temperature sensor is pulled by some external object or repeatedly moved up and down due to contact with the cooking container, the connection or attachment part of the lead wire may become dislocated or disconnected, and the role of the temperature sensor may be lost. It had become impossible to do so.

方は、前者を少し強くしている。In Fig. 1, a temperature sensor 3 is arranged in the center of the burner 1 and the heat shield cylinder 2, and a hollow guide shaft is inserted into the guide hole 7.7' of the sensor mounting base 6, which is fixed to the burner ridge 4 of the stove with screws 5. 8 is inserted and prevented from coming off with a cotter pin 9, and a spring 11 is set between a spring receiver 10 fixed to the guide shaft 8 and the sensor mounting base 6 to always urge the guide shaft 8 upward. A guide tube 12 having a plurality of slot holes 13 is welded to the upper end of the guide shaft 8. A thermal head 14 is made of a thin plate of stainless steel, and has a plurality of claws 15 at its lower end. Guide tube 12
The slit hole 13 and the pawl 15 of the thermal head 14 correspond to each other, and after the thermal head 14 is inserted into the guide cylinder 12, the pawl 15 is bent toward the slit hole 13 and the spring 16 is used to pop it out. It will be stopped. Guide tube 1
2 and the thermal head 14 have a gap 17 in which they can slide and move up and down, and are elastically held by a spring 16 so that the thermal head 14 can move within a regulated range. Here, the thermal head 14 with 16 springs moves up and down to maintain good contact with the cooking container.
Reference numeral 1 is for being pressed down when various cooking containers are placed thereon, and the initial pressure of the spring 11 and spring 16 is slightly stronger than the former.

Further, the lead wire 231d is inserted through the guide shaft 8, and by pressing the holding plate 25 with the screw 26 at the lower part thereof and pressing the lead wire 23, the lead wire 23 is cut off from any external tensile load.

略している。27 is a known sensor element using a thermocouple;
It is inserted into the two through-holes of the recess 28 at the center of the upper surface of 4, and is brazed and welded with a metal having excellent thermal conductivity, such as silver alloy 29. 30 is an insulator into which a thermal lightning pair 27 is inserted, and is fixed with a shrink tube 31. The lead wire 23 of the thermocouple 27 (which becomes the covered wire of the thermocouple) is formed with an expandable portion 24 as in FIG. 1, and performs the same function, and the lower fixation is the same as in FIG. 1 and is therefore omitted.
ここで、感熱ヘッド１４の一ヒ下動に対応したリード線

確実にできる。Next, Figures 3 and 4 are detailed views of fixing the lead wire 23 below the guide shaft 80. This is because, as explained in FIG. 1, even if the sensor element is the thermistor 18, electroless couple 27, etc., the lead wire 23 is fixed in the same way. In this case, the lower part of the guide shaft 8 is formed into a semi-circular diameter shape 81 (cross-sectional shape), and the lead wire 23 is connected to the inner surface of the guide shaft 8 with a screw 26 through a holding plate 25 toward the flat side 32. If it is pressed and fixed, it can be done reliably without damaging the lead wire 23.

制御を行う。To explain the operation, when a cooking container (not shown) is placed on the burner 1-, the thermal head 14 first makes good contact with the outer bottom surface of the cooking container by the spring 16, and then the spring 11 is pushed down to start cooking. The container is placed. When heating the burner 1, a sensor element detects the temperature change, and is connected to an electric circuit (not shown) through a lead wire 23, thereby controlling the temperature of the stove.

ある。The lead wire 23 that is inserted through the guide shaft 8 is fixed below the guide shaft 8 to prevent tensile loads from the outside, and forms an elastic part 24 of the lead wire 23 on one side of the guide shaft 8 to prevent tension from external tensile loads. In order to absorb vertical movement of the heat-sensitive head 14 due to contact, the cooking container and the heat-sensitive head 14 are always in good contact, and breakage of the lead wire 23 is prevented.
