JPS62169927A - Thermocouple fixing device for gas instrument - Google Patents

Abstract

PURPOSE:To permit to fix a thermocouple to the main body of a burner very simply and improve the working efficiency of the title device by a method wherein the thermocouple is fixed from the up-and-down direction of a penetrating hole by a flange, provided on the thermocouple, and a spring, movable into circumferential direction regulated by the thermocouple. CONSTITUTION:A thermocouple 14 is inserted into a penetrating hole 16 and is fixed thereto by a flange 18, provided on the thermocouple 14, at the upper side of the penetrating hole 16 while the same is fixed at the lower side of the same hole 16 by a spring 17 movable into a circumferential direction regulated by the thermocouple 14. According to this constitution, screw threading work may become unnecessary and the thermocouple 14 may be attached by one action of inserting the same into the hole 16 until the same is fixed to the main body 11 of a burner by the spring 17.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a thermocouple fixing device for use in gas appliances, particularly gas staples.

BACKGROUND OF THE INVENTION In recent years, household gas appliances in general, and gas staples in particular, have increasingly come equipped with safety devices that use thermocouples to prevent gas from burning out when boiling over from stove burners. However, due to the nature of thermocouples, screws are used to securely fix them while maintaining a certain distance from the combustion hole.

Hereinafter, a conventional thermal lightning pair fixing device will be explained based on FIG. 3. In the figure, 1 is the burner body.

2 is a burner cap having a combustion flame hole 3; 4 is a thermocouple attached to the burner body 1; and 5 is a screw for fixing the thermocouple 4. Fixing the thermocouple 4 to the burner body 1 is as follows:
The thermocouple 4 is inserted into the through hole 7 of the protrusion 6 provided in the burner body 1, and tightened with screws 5 from the sides of the thermocouple 4.

Problems to be Solved by the Invention However, in the case of the above-mentioned configuration, not only does it require thread cutting for screw attachment.

Since it is necessary to tighten the screws 5 from the lateral direction of the burner body 1, the thermocouple 4 must be attached to the burner body 1 separately first, which makes assembly troublesome.

The present invention is intended to solve these problems, and aims to improve work efficiency by extremely easily fixing the thermal lightning pair to the burner body.

Means for solving the problem In order to solve this problem, the present invention provides a burner body,
A through hole is formed in the protrusion provided on the burner body, and a thermocouple is inserted into the through hole, and the thermocouple is connected to a flange provided on the thermocouple and a thermocouple. It is fixed from above and below the through hole using a spring that is movable in a regulated circumferential direction.

This configuration not only eliminates the need for conventional thread cutting, but also allows the thermocouple to be inserted into the burner body until it is fixed to the burner body by a circumferentially movable spring regulated by the thermocouple. Can be installed with one touch.

Example Below, one drawing (Fig. 1, 2
The explanation will be based on Figure).

In the figure, 11 is the burner body, 12 is a burner cap having a combustion flame hole 13, 14 is a thermocouple attached to the through hole 16 of the protrusion 15 of the burner body 11, and 7 is the circumference regulated by the thermocouple 14. It is a spring that can move in one direction. The thermocouple 14 is inserted into the through hole 16 and fixed. At this time, the thermocouple 14 is fixed by the collar 18 provided on the thermocouple 14 on the upper side of the through-hole holder, and by the spring 17 on the lower side. There is.

Effects of the Invention As described above, according to the present invention, the through hole provided in the burner body is provided with a thermocouple on one side by a collar provided on the thermocouple and on the other side by a circumferentially movable spring regulated by the thermocouple. By fixing the pair, it is possible to assemble it with one touch, and it is possible to improve work efficiency.
