Description

[Detailed Description of the Invention] The present invention relates to improvements in blocks such as water heaters and gas blocks.

Conventionally, for combustion appliances such as water heaters, the primary issue was how they were installed.

That is, they were normally installed vertically as shown in FIGS. 1 and 2.

However, in recent years, attention has been paid to the effective use of room space in consideration of livability.

However, because conventional water heaters have parts that have directional properties, there is no flexibility in the installation direction.If you want to change the installation direction of the appliance, you need a water block and a gas block that are designed for a specific installation direction. They were also non-transferable and incompatible with water heaters installed in other directions.

An example of such a conventional water block and gas block will be explained with reference to FIGS. 1 and 2.

A main solenoid valve 2, a gas pressure regulator 3, a pilot solenoid valve 4, etc. are provided between the gas supply pipe 1 and the gas conduit 5 leading to the mixing pipe, and these are usually installed in different directions. Moreover, the connection port did not have a joint that could change the direction of the supply pipe 1 and the conduit 5.

Therefore, it is not possible to change the directions of the supply pipe 1 and the conduit 5 without changing the directions of the components 2 to 4 above.
For example, when gas is supplied vertically and horizontally, separate gas blocks are used and cannot be converted to each other.

Also connected to the water block 10 are a water supply pipe 6, an outgoing water pipe 7 for leading to the heat exchanger, a condensate pipe 8 returning from the heat exchanger, a hot water supply pipe 9, etc. 9
Since these are usually made of flexible pipes, the water supply and hot water supply direction can be changed by bending the pipes. For example, even if it has a joint that can change the direction, it is not possible to change the direction of the outgoing water pipe 7 and the condensing water pipe 8 without changing the direction of the water block.
Therefore, when changing the flow direction of water, another block must be used, which has the disadvantage that it is necessary to change the block depending on the flow direction.

The present invention is intended to improve the above-mentioned drawbacks, and one embodiment thereof will be described below with reference to FIG.

The air supplied by the supply/exhaust blower 11 is transferred to the mixing pipe 1
A burner 13, a combustion chamber 14, a heat exchanger 15, and an exhaust hood, which are mixed with fuel gas at step 2 and connected to the mixing pipe 12, are connected in sequence.

Fuel gas is supplied from a supply pipe 1 to a gas block A consisting of a main solenoid valve 2, a gas pressure regulator 3, a pilot solenoid valve 4, etc.
After passing through, it is guided to the mixing tube 2.

Water enters from the water supply pipe 6, passes through a water block 10 consisting of a water valve, a bypass valve, etc., and then passes through the water supply pipe 7 to the heat exchanger 1.
5, passes through an outgoing water pipe 8, returns to the water block 10, and is supplied through a hot water supply pipe 9.

The details of the gas floc A in the above embodiment are shown in FIG. 4 and will be explained below.

A main solenoid valve 2, a gas pressure regulator 3, and a pilot solenoid valve 4 are arranged on a coaxial B-axis, and a connecting portion between a gas supply pipe 1 and a conduit 5 is disposed on the B-axis, and the gas block and The joint 1, which has no directionality like a fukuro nut, is
7 is provided.

When the gas flow direction is changed from the α direction to the β direction, the supply pipe 1 is moved around the B axis at the joint 17.
And the conduit 5 can be rotated in any direction.

An embodiment of the present invention relating to a water block is shown in FIG. 5 and will be described below.

The outgoing water pipe 7 and the condensing water pipe 8 are constructed on a coaxial C axis, and a joint 19 is provided at the joint with the water block 18 to provide directionality.

When the flow of water is changed from α to β direction, the outgoing water pipe 7 and the condensing water pipe 8 can be rotated in any direction at the joint 19 around the C-axis.

As described above, according to the present invention, the following effects can be obtained by configuring the water block and the gas block.

1. Even if a gas block, water block, etc. has a component with directionality, it is possible to change the flow of gas and water in any direction without changing the direction of the block.

Therefore, when changing the installation direction of the water heater, it is possible to install the appliance in any direction by simply changing the piping direction.

2 Components connected to the water block, gas block, and the above-mentioned blocks are compatible because common parts can be used regardless of the installation direction of the water heater, and the number of types of parts is small. As a result, costs can be reduced.
