Description

[Detailed description of the invention] The present invention relates to a manifold (hereinafter simply referred to as a manifold) in a gas combustion device, and more specifically, to a manifold in which a group of non-nozzles for a bath kettle and a group of non-nozzles for a water boiler are protruded from the left and right sides of a manifold pipe. It is.

In the gas combustion device used in the conventional gas bath kettle,
Generally, the manifold and pilot nozzle are separate and fixedly installed within the container housing.

Therefore, each of the above-mentioned installations requires parts and fixtures, and the entire device is complicated, and when repairing the device or changing the nozzle when changing the amount of heat, the work of disassembling and reassembling the device is required. has the disadvantage that it requires a lot of effort.

The purpose of the present invention is to eliminate the above-mentioned drawbacks, and also for bathtubs with a built-in water heater, where the bathtub is located on the left side and the water heater is on the right side, and vice versa. This product provides a manifold that can be used as one type of manifold for both types of manifolds.The feature is that non-nozzle groups are protruded from the left and right sides of the manifold pipe, and these non-nozzle groups The pilot nozzle mounting part is located in the middle of the pipe and has a pilot nozzle mounting part projecting symmetrically from top to bottom.

Hereinafter, one embodiment of the manifold according to the present invention illustrated in the drawings will be described in detail.

FIG. 1 is a schematic explanatory view of one embodiment of the manifold of the present invention, showing the state when it is disassembled from the gas governor body, and FIG. 3 is a sectional view taken along the line AA' in FIG. 1.

As shown in FIGS. 1 and 2, the manifold body 1 according to the present invention has a non-nozzle group 2, 2.2 coaxially protruding from the left side of a manifold pipe 1a, and a non-nozzle group 3, 3.2 on the right side. 3 are coaxially protruding from each other, while their non-nozzle groups 2°2.2 and 3,3.3
Attach the two pilot nozzle mounting parts 4 and 5 to the middle part of the
It is protruded symmetrically from the bottom.

The non-nozzle groups 2, 2.2, and 3, 3.3 protruding from the left and right sides of the manifold tube 1a are protruded from the horizontal central axis of the manifold tube 1a, and the pilot nozzle mounting portion 4 , 5, the non-nozzle groups 2, 2.2 and 3, 3.3 are mounted so as to protrude at vertically symmetrical positions across the positions.

That is, the pilot nozzle mounting portion 4 protruding downward is located below the non-nozzle groups 2, 2.2 and 3, 3.3, and the pilot nozzle mounting portion 5 protruding upward is located below the non-nozzle groups 2, 2.2 and 3, 3.3. The mountings 2, 3, and 3.3 are protruded at positions symmetrical to the protruding position of the lower pilot nozzle mounting portion 4 across the positions.

On the other hand, the gas governor body 6 has main gas supply passages 7 and 8 on the left and right sides for supplying main gas to the manifold body 1, and a pilot gas supply passage 9 is provided in the middle of these main gas supply passages 7 and 8. It is formed.

An attachment port 9a of the pilot gas supply path 9 to the manifold is formed at a position connected to a lower pilot nozzle attachment portion 4 protruding from the manifold pipe 1a.

Also, a main gas supply path 7 formed in the gas governor body 6
It goes without saying that the manifold mounting lowers a and 3a of .

In the figure, 12 is a gas governor body mounting part, 13 is a screw mounting hole, 14 is a screw, and 15 is a manifold mounting part.

The manifold according to the present invention has the above-mentioned configuration,
By attaching the gas governor body attachment part 12 of the manifold body 1 to the manifold body attachment part 15 of the gas governor body 6 with screws 14 or the like, a pilot nozzle attachment part 14 on the lower side protruding from the manifold body 1 and the gas governor body 6 are formed. The pilot gas supply path 9a is connected, and the main gas supply paths 7, 8 formed in the gas governor body 6 and the main gas supply section 10.11 formed in the manifold body 1 are connected, and the pilot gas and main gas are supplied to each burner. can be supplied.

For example, if the nozzle group 2.2.2 protruding from the left side of the manifold pipe 1a is used for a water heater, and the nozzle group 3.2.2 protruding from the right side is used for a bathtub, then In the case of a gas bath kettle of the type where the bath kettle is installed, use it as is, and in the case of a gas bath kettle of the opposite type to the above-mentioned one, turn the manifold body 1 upside down and use it on the left side. Nozzle group 2, 2.2 and right nozzle group 3,
3.3 can be used in the opposite position.

At this time, since the pilot nozzle attachment parts are positioned symmetrically with each other as described above, they can be connected accurately without any displacement.

As described in the embodiments above, according to the manifold according to the present invention, the pilot nozzle mounting portion is integrally protruded from the manifold body, so it is no longer necessary to install the pilot nozzle as a separate part as in the past. Therefore, the number of parts can be reduced.

Furthermore, by taking out the manifold body when repairing the nozzle or changing the amount of heat, the main nozzle and pilot nozzle can be adjusted, and the work of attaching the gas governor body and the manifold body becomes easy.

Furthermore, by protruding the pilot nozzle mounting parts symmetrically upward and downward, the left side
The right-side type also has the advantage of being able to reduce costs because it can be made with just one type of manifold body.
