DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a metal holder made of a non-porous copper plate, which is formed in a cylindrical shape with an upper end opening 2, and has a stepped portion 4 having a through hole 3 at the center by being narrowed in the upper and lower middle. Non-perforated gold in the upper end opening 2
The metal cap body 5 made of metal is put on. The metal cap body 5 is fitted to the metal holder 1 by a simple concave-convex engaging portion. The upper end of a vertical fixed support cylinder 6 is inserted into the through hole 3 provided at the center of the step portion 4 so as to be vertically slidable relatively . The upper end of the fixed support cylinder 6 projects above the step 4 of the metal holder 1,
The tray 7 is fixed there. The receiving tray 7 is in sliding contact with the inner wall of the metal holder 1, the fixed support cylinder 6 and the receiving tray 7 are fixed, and the metal holder 1 moves up and down.

A coil spring 8 is provided between the tray 7 and the metal cap 5. Accordingly, the metal cap body 5 is
Resilient due to the upward movement, the hold-down et <br/> is from above More cooking tool lowered against the elastic force of the coil spring 8.

At the lower surface of the metal cap body 5, brass fixing brackets 9 are spot-welded at approximately four places. Fixture 9
A contact plate portion 10 for contacting and spot welding the lower surface of the metal cap body 5; a storage portion 12 of a thermistor 11 formed by bulging a central portion of the contact plate portion 10 downward; Lead wire fixing portion 1 provided with slit 13 from storage portion 12
4. The slit 13 is used to prevent the collapse of the lead wire fixing portion 14 from reaching the storage portion 12 as described later, and therefore, the slit 13 may have a width within an intended range.

When viewed from the side, both the storage section 12 and the lead wire fixing section 14 are substantially U-shaped (they may be U-shaped and may not be the same height), and the thermistor 11 is attached to the tip. With a certain lead wire 15, the portion of the thermistor 11 is pushed into the storage portion 12, and only the portion of the lead wire fixing portion 14 is crushed and fixed. At this time, a filler 16 such as silicon grease, epoxy resin, ceramic adhesive, or the like is filled in the storage section 12. The Teflon tube 22 is placed between the lead wires 15 where the lead wire 15 is held.
It is good to coat with.

Reference numeral 17 denotes a cooking utensil such as a tempura pan, reference numeral 18 denotes a fixed stand on the gas stand side, and the fixed support cylinder 6 is a fixed stand 1
It is fixed to 8. 19 is a cord connected to the lead 15. The metal holder 1 can move only up and down with respect to the tray 7 and does not rotate. In order to prevent the metal holder 1 from rotating, a vertical ridge 20 is formed on the inner wall of the metal holder 1. An engaging portion 21 that engages with the vertical ridge 20 is formed on the outer periphery.

[0011]

Next, the operation will be described. In the embodiment of the present invention, the contact plate portion 10 of the fixing bracket 9 is brought into contact with the lower surface of the metal cap body 5 to perform spot welding. After that, the filler 16 is packed in the storage portion 12 of the fixture 9, the thermistor 11 is attached to the tip, and the tip of the lead wire 15 surrounded by the Teflon tube 22 is held. Push it into the storage section 12 to secure the lead wire fixing section 1
Crush part 4 Then, the collapse of the lead wire fixing portion 14 does not reach the storage portion 12 due to the slit 13, so that the lead wire fixing portion 14 can be sufficiently crushed, and the lead wire 15 can be fixed by crushing the lead wire fixing portion 14. it can.

The metal cap body 5 to which the thermistor 11 is fixed is
The upper end of a vertical fixed support cylinder 6 is fitted over the upper opening 2 of the metal holder 1 made of a copper plate, and the upper end of the vertical fixed support cylinder 6 is vertically movably fitted into the through hole 3 formed at the center of the step portion 4 of the metal holder 1. The receiving tray 7 is fixed to the upper end of the support cylinder 6, an engaging portion 21 is formed on the peripheral surface of the receiving tray 7, and the engaging portion 21 is engaged with the vertical ridge 20 formed on the inner surface of the metal holder 1. . Then, saucer 7
A coil spring 8 is provided between the coil cap 8 and the metal cap 5.

In this configuration, when the metal cap 5 is brought into contact with the lower surface of the cooker 17, the metal cap 5 is pushed by the cooker 17 and descends against the elasticity of the coil spring 8.
Since the vertical ridge 20 formed on the inner surface of the metal holder 1 is engaged with the engaging portion 21 formed on the peripheral surface of the tray 7, the metal holder 1 does not rotate, and the metal holder 1 only moves up and down. off and lead wire 15 of a metallic cap body 51 of the thermistor 11
There is no twist or disconnection. In addition, the non-porous metal holder 1
Formed on the peripheral surface of the saucer 7 on the vertical ridge 20 formed on the inner surface
Because it is structured to move up and down by engaging with the engaging portion 21,
Even if mushroom spilled juice is splashed, the juice will not enter the metal holder 1.
Since there is no insertion, breakage of the lead wire 15 or malfunction may occur.
No.

[0014]
