BRIEF DESCRIPTION OF THE DRAWINGS FIG.
Reference numeral 1 denotes a metal holder made of a copper plate (or brass or stainless steel), and an upper end 2 is formed in an open cylindrical shape. The lower end 3 of the embodiment is narrowed and has a bottom wall 5 having a small-diameter through hole 4 at the center.
There is. A metal cap 6 is put on the upper end 2.
The metal cap body 6 is fitted to the upper end 2 of the metal holder 1 so as not to come off by simple concave and convex engagement.

That is, the cap body 6 protrudes inward toward the upper part,
Upper plurality pressed form inward protrusion 7 with a horizontal engaging portion 7 'on the the upper end 2 of the metal holder 1, which direction of the cross-sectional
The surface is also continuous, protruding inward toward the top, and
When the metal cap 6 is fitted, the horizontal engagement portion 7 '
A plurality of engaging recesses 8 having a horizontal hook 8 '
Pressing is performed, and the inner projection 7 is engaged with the engaging recess 8 to be fixed. Inward projection 7 protrudes as an upper inwardly, horizontal engaging portion
7 ' engages with the horizontal catch 8' so that once engaged, it cannot be disengaged.

A vertical fixed support cylinder 9 is fitted in the through hole 4 formed in the bottom wall 5 so as to be slidable up and down. The upper end of the support tube 9 protrudes into the metal holder 1, where the sliding plate 10
Is fixed ( Fig. 1 ). The support cylinder 9 and the slide plate 10 may be separately caulked or may be integrated. The sliding plate 10 can move up and down along the inner wall surface 11 of the metal holder 1.

[0008] A coil spring 12 is provided between the upper surface of the sliding plate 10 and the lower surface of the metal cap 6. Therefore, the metal cap 6 always moves upward due to the elasticity of the coil spring 12,
When pressed on the lower surface of the cooking utensil, it descends against the elasticity of the coil spring 12.

On the lower surface of the metal cap 6, a fixing bracket 13 made of a copper plate (or brass or stainless steel) is spot-welded. The fixing bracket 13 has a storage section 15 for a thermistor 14. 16 is a lead wire of the thermistor 14.

The sliding plate 10 of the embodiment can slide only up and down with respect to the metal holder 1, but does not rotate. Therefore, a vertical ridge 17 is formed on the inner wall of the metal holder 1, and a vertical ridge 18 that engages with the vertical ridge 17 is formed on the slide plate 10.

[0011]

Next, the operation will be described. A sliding plate 10 is fixed to the upper end of the fixed support tube 9, and the fixed support tube 9 is vertically slidably fitted into the through hole 4 formed at the center of the bottom wall 5 of the metal holder 1.
When the metal cap body 6 to which the thermistor 14 is fixed is put on the upper end 2 of the metal holder 1 after inserting the coil spring 12, the metal holder 1 and the metal cap body 6 are vertically moved with respect to the vertical fixed support cylinder 9 by the elasticity of the coil spring 12. Sliding fit.

In the above case, the metal holder 1 and the metal cap 6
Is projected inward toward the upper part of the cap body 6, and
Pressing and forming a plurality of inward projections 7 having horizontal engagement portions 7 ′,
The cross section in any direction is cut at the upper end 2 of the metal holder 1.
It has no eyes, protrudes inward toward the top, and the metal
When the cap body 6 is fitted, the horizontal engaging portion 7 'is engaged.
Pressing and forming a plurality of engaging recesses 8 having horizontal catching portions 8 '
Then, the inward projection 7 is engaged with the engaging recess 8 and is fixed.
So that the horizontal engaging portion 7 'is engaged with the horizontal catching portion 8'.
No, once it is engaged, it will not come off. Not only that,
There is no intrusion of soup.

[0013]

[Effects of the Invention] A known cap attachment device for a thermistor for a cooker
The metal cap is located in the shape of an arc-shaped inward protrusion on the peripheral wall of the metal cap and a metal holder.
Because it is the engagement of the arc-shaped concave part of the da, like Chinese cuisine
In dishes that hit the pot violently, the engagement of the metal cap may
Lumi, thermistor malfunctions when covered with spilled juice
There was fear . However, in the present invention, the thermistor 14 is fixed to the lower surface side of the metal cap body 6, the metal cap body 6 is fitted to the upper end 2 of the cylindrical metal holder 1, and the metal holder 1 and the metal cap body 6 are fixed. in things which is adapted to detect the temperature and Tamagi the lower surface of the cooking device moves upward by the elastic force of the coil spring 12, the peripheral wall of the metallic cap body 6, also without a break in any direction of the cross-section, as the upper Protruding inward, horizontal engaging part at upper end
A plurality of inward projections 7 having a 7 ' are formed by pressing, and the upper end 2 of the metal holder 1 has no cut in any direction in cross section.
The metal cap body 6 protrudes inward toward the upper part and fits on the outer surface of the upper end.
The horizontal hook that the horizontal engaging portion 7 'engages when
Since the cap body mounting device of the thermistor for cooking utensil is formed by pressing a plurality of the engaging recesses 8 having the ridges 8 ′, the circumferential wall of the metal cap body 6 has cuts in any direction.
The upper end of the horizontal engaging portion 7 '
A plurality of inward projections 7 are formed by pressing, and the metal holder 1 is formed.
The upper end 2 has no cut in any direction,
The metal cap body 6 protrudes inward and fits on the outer surface of the upper end.
Horizontal hooking part with which the horizontal engaging part 7 'is engaged
Since a plurality of engaging recesses 8 having 8 'are formed by pressing,
Engagement is easier than in the example . B. The engagement between the horizontal engaging portion 7 'and the horizontal catching portion 8'
Once you engage, it ’s Chinese food because it does n’t come off
Even a dish that beats the sea urchin vigorously will not malfunction.
No.
