Description

[Detailed Description of the Invention] The present invention relates to a water heater, for example, an oil water heater, and more specifically, a hot water tank, water supply pipes connected to the tank, hot water supply pipes, and valves installed in the middle of these pipes are entirely covered with an exterior body. This relates to an enclosed water heater, and the objective is to improve the placement of the valve and the joint used to install it so that the exterior body can be used to connect the water supply pipe and hot water pipe to external piping. From either the left or right side,
To easily carry out the process by simply changing the orientation direction of water supply pipes and hot water supply pipes without changing their lengths.

Next, one embodiment of the present invention will be described based on the drawings.

Figure 1 is an overall partially cutaway view of an oil water heater as an example of a water heater, viewed from the side, and Figure 2 is a partially cutaway overall view of the water heater viewed from the front. As shown in these figures, there is a hot water tank 1, a water supply pipe 2 whose one end is connected to the tank 1, a hot water supply pipe 3, a pressure reducing valve 4 provided in the middle of the water supply pipe 2, a safety valve 5, and a hot water supply pipe 3. and a safety valve 6 provided in the middle of the hot water tank 1 and water supply pipe 2.
, the hot water supply pipe 3 and the valves 4, 5, 6 are entirely surrounded by, for example, a rectangular exterior body 7.

The inner surface of this exterior body 7 includes glass wool, rock wool,
A heat insulating material 8 such as styrofoam or urethane foam is attached, and a side-opening door 9 is provided at the front.

Further, on both the left and right side surfaces 7a) and 7b, there are openings 10 where the connection ports 2a and 3a of the water supply pipe 2 and the hot water supply pipe 3 with external pipes are located, and discharge ports connected to the safety valves 5 and 6. Openings 13 for positioning the discharge ports 11a, 12a of the pipes 11.12, and a discharge port 14 for draining water inside the machine.
Openings 15 are respectively formed in which the openings 15 are erected.

Therefore, the present invention has a hot water tank 1 and a water supply pipe 2 as described above.
, the entire hot water supply pipe 3 and valves 4, 5.6 are surrounded by an exterior body 7, and a branch joint 16 and a cheese joint 17 are used to attach the valves 4, 5.6 and these valves to the water supply pipe 2 and the hot water supply pipe 3.
．． It is characterized in that a joint such as No. 18 is arranged on a vertical line P at the center of the exterior body 7 in the left-right width direction.

In the figure, reference numeral 19 is a control unit provided below the water supply pipe 2, which controls the temperature of the hot water tank 1 and prevents it from being heated dry.

Reference numeral 20 denotes a saucer provided between the control unit 19 and the water supply pipe 2, which collects water droplets adhering to the water supply pipe 2 and the inner surface of the top plate of the exterior body 7, or water falling from each valve. Protects the control unit 19 from water droplets.

The water droplets collected in the saucer 20 are discharged into the machine through the drain pipe 21 and the drain port 4.

22 is a chimney.

Therefore, according to the present invention, when connecting the water supply pipe 2 and the hot water supply pipe 3 with external piping, only by changing the orientation direction of the water supply pipe 2 and the hot water supply pipe 3, it is possible to connect the water supply pipe 2 and the hot water supply pipe 3 to either the left or right side surface 7a, 7 of the exterior body 7. You can also connect from b.

That is, in the illustrated example, the water supply pipe and hot water supply pipe connection ports 2a, 3a
is located at the opening 10 on the right side surface 7a, but the horizontal pipe portions 2b and 3b from the connection ports 2a and 3a to the cheese joint 17 and 18 are removed from the cheese joint, and the other parts of the joint are removed. If they are connected to the ends, the connection ports 2a and 3a can be positioned exactly at the opening 10 on the left side surface 7b of the exterior body.

Also, the reason why the discharge ports 11a and 12a of the safety valve discharge pipe 11.12 are changed to the left side surface 7b is because the discharge pipe 11.12 is flexible, so only the discharge ports 11a and 12a are removed and they are moved to the left side surface 7b. This can be done simply by directing the discharge pipe toward the opening, but in this case as well, since the safety valves 5 and 6 are located on the vertical line P, there is an advantage that there is no need to replace the discharge pipe with a discharge pipe of a different length.

In this way, according to the present invention, connections with external piping can be made by simply replacing the ones in use without having to replace water supply pipes, hot water supply pipes, discharge pipes, etc. with ones of different lengths. Since it can be performed on either the left or right side of the body,
This is extremely convenient when it is necessary to change the connection direction with external piping depending on the conditions of the installation location.

In addition, if the opening on the side of the exterior body where the connection port with external piping, discharge port, discharge port, etc. is not located, is closed with a backing plate such as a rubber plate to prevent dirt and dust from entering the inside of the machine. It is convenient to be able to prevent this.
