Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a burner and a structure around the burner of a gas stove, such as a gas stove or a gas range.

Prior Art The structure of a conventional example will be explained based on FIG. 2. A burner mixing pipe 1 is fixed to a device body 8,
forms the upper lid of the appliance and has openings through which the burner mixing tube 1, the spark plug 4, and the thermocouple 5 project upward. The burner head 2 fits into the burner mixing tube and is supported on the saucepan. Burner cover 7
This is to prevent boiled liquid from entering the inside from the top, and is approximately conical in shape. It has openings from which the burner head, spark plug, and thermocouple protrude, and is held on a liquid saucer. . The burner cap 3 is fitted and supported on the upper part of the burner head, and forms a burner opening by the toothed surface formed on the back surface and the upper surface of the burner head. Here, the discharge interval formed between the tip of the spark plug and the back surface of the burner cap and the relative position between the flame port and the thermocouple must be kept constant in order to stabilize the ignition performance and flame detection performance, respectively. , the spark plug and thermocouple are fixed to the burner head with screws or the like.

Problems to be Solved by the Invention However, in this configuration, the spark plug 4 and thermocouple 5 are fixed to the burner head 2, and their lead wires are connected and fixed to the appliance main body 8 through the opening of the juice pan 6. Therefore, attaching and detaching the juice pan and burner head, which normally require cleaning and maintenance, involves removing the spark plug and thermocouple, which is difficult. There were problems such as damage to the lead wires.

Therefore, an object of the present invention is to facilitate cleaning and maintenance by providing a structure in which the burner head and juice pan can be easily attached and detached without removing the spark plug or thermocouple.

Means for Solving the Problems In order to achieve the above object, the present invention provides a burner mixing pipe which is fixed to a device body and has an upper cylindrical part having a constant height in the vertical direction, and which supports and fixes a spark plug and a thermocouple. and a mounting bracket that is fitted and fixed to the upper cylindrical part of the burner mixing pipe, and an opening that allows the upper cylindrical part of the burner mixing pipe, the spark plug, and the thermocouple to protrude upward; A juice pan removably provided on the upper part of the main body; a burner head rotatable horizontally in the upper cylindrical part of the burner mixing pipe and removably fitted from the upper part;
The burner cover has a substantially conical shape, has a fitting hole through which the spark plug/thermocouple can protrude upward at a predetermined position, and is detachably fitted into the burner head from above.

Function In the gas stove of the present invention, the ignition plug or thermocouple is first fixed to the upper cylindrical part provided at the upper part of the burner mixing pipe as a reference axis, and then the burner head is held in a predetermined position via the burner cover. This structure ensures the relative position of the burner head and the ignition plug or thermocouple, and facilitates attachment and detachment of the burner head without removing the ignition plug or thermocouple.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the drawings.

In FIG. 1, a burner mixing tube 1 having an upper cylindrical portion having a constant height in the vertical direction is fixed to a device main body 8, and mounting brackets 9a and 9b and a burner head are used to support and fix a spark plug 4 and a thermocouple 5, respectively. 2
are fitted into the upper cylindrical portion of the burner mixing tube 1, respectively, and are capable of rotating in the horizontal direction. The juice tray 6 has an opening through which the burner mixing tube 1, the spark plug 4, and the thermocouple 5 can protrude from the top, and can be detachably attached to the top of the device body 8. The burner cover 7 is configured to be removably fitted into the burner head 2, and fitting holes 10 and 11 are provided at opposing positions of the spark plug 4 and thermocouple 5, respectively.
are provided, the burner head 2 and the spark plug 4
and the thermocouple 5 so that their horizontal relative positions are kept constant. The burner cap 3 is configured to be detachably fitted into a fixed position above the burner head 2.

In this way, the ignition plug 4 and thermocouple 5 can be set with the upper cylindrical part of the burner fitting tube 1 as the same reference axis.
Although there is a relative displacement in the rotation angle of the burner head 2 in the horizontal direction, the relative displacement in the radial direction can be accurately and reliably kept constant. By fitting the burner cover 7, the relative displacement in the rotation angle can be The displacement can be accurately and reliably held constant. By making each of the mounting fittings 9a and 9b and the burner head 2 horizontally rotatable independently, minute variations in dimensions including the burner cover 7 can be absorbed.

That is, the burner cap 3, spark plug 4, and thermocouple 5 for the original ignition performance and flame detection performance.
The respective intervals of the burner cap 3, burner cover 7,
The burner head 2 and juice pan 6 can be easily attached and detached for easy cleaning and maintenance, and the spark plug 4 and thermocouple 5 can be easily attached and detached even after repeated attachment and detachment.
It is not intended to damage.

Effects of the Invention As described above, according to the present invention, the burner head and the mounting bracket for supporting and fixing the thermocouple and the ignition plug are fitted to the upper cylindrical part of the burner mixing pipe with the same reference axis, so that each is horizontal. In addition to allowing the burner cover to rotate independently in the burner head, holes for fitting the thermocouple and the spark plug are provided at predetermined positions in the burner cover to hold the fitting, so that the spark plug and the thermocouple can be rotated independently relative to the burner head. The horizontal relative position can be maintained constant, and the burner head can be easily attached and detached without removing the spark plug or thermocouple during cleaning or maintenance, and the spark plug or thermocouple will not be damaged even if it is repeatedly attached and detached. It is not a real thing, but it is extremely advantageous in practice.
