Description

[Detailed Description of the Invention] The present invention relates to a water heater of a type that is installed along the side wall of a house through which the main body of the water heater is disposed through a supply/exhaust pipe or other cylindrical body.

Conventionally, in this type of water heater, as shown in FIG. 1, for example, there is a gap between the water heater main body 1 and the side wall a corresponding to the protruding width of the opening edge 2a of the cylindrical body 2 protruding from the inner surface thereof. In this case, a sealing member C is generally attached to the opening edge 2a to prevent wind and rain from entering through the through hole in the side wall a, as shown in Fig. 2. , the protruding width and therefore the gap also become larger, which is not only unsightly but also unfavorable from a sanitary perspective as dirt and the like accumulate in the gap.In addition, this device has a connecting tube 4 that allows the combustion chamber 3 in the main body 1 of the water heater to be freely removed. When it is necessary to move the main body 1 for maintenance management, the main body 1 can be moved without removing the connecting cylinder 4 and moving the adjacent object d such as an adjacent cooking table. However, when the drawer is pulled out, the dirt that has accumulated in the gap is drawn out to the front, resulting in an inconvenience such as extra effort is required to clean it.

The purpose of the present invention is to provide a water heater that eliminates such inconveniences, and the main body 1 of the water heater is installed along the side wall a of a house through which the cylindrical body 2 such as the supply/exhaust pipe is disposed. The combustion chamber 3 in the water heater main body 1 is connected to the opening edge 2a of the cylinder body 2 protruding from the inner surface of the side wall a through a removable connecting cylinder 4 extending laterally. A recess 5 that does not reach the top or front surface but reaches the rear surface is formed on the side surface of the water heater body 1 opposite to the side wall a, and the opening edge 2a is exposed within the recess 5.

The recess 5 may be formed by recessing a part of the side plate 6 of the main body 1 of the water heater, as shown in FIGS. The opening/closing door 7 and the top plate 8 on the top surface are made to protrude to the side of the side plate 6, and these three people 6
, 7.8, any of the equations formed over the entire side surface is arbitrary.

The connecting tube 4 is removably screwed onto the upper surface of the combustion chamber 3, and has a window hole 6 bored in the side plate 6 of the main body 10 of the water heater at its tip.
The cylinder body 2 is connected to the opening edge 2a of the cylindrical body 2 by protruding sideways from the opening edge 2a of the cylindrical body 2.
The present invention is not limited to the double internal and external supply/exhaust pipe as shown in the figure, but may be configured as a supply cylinder that only supplies air to the combustion chamber 3 or an exhaust pipe that only exhausts air.

As described above, according to the present invention, a recess 5 is formed on the side surface of the water heater main body 1, and does not reach the top or front surface, but reaches the rear surface, and the opening edge 2a of the cylindrical body 2 is exposed within the recess 5. , the main body 1 can be placed in close contact with the side wall a on its top and front surface, and has a good appearance, prevents dirt from accumulating between the main body 1 and the side wall a, and has an opening. The edge 2a is located inside the water heater body 1 within the recess 5 that reaches the rear surface.
The main body 1 will not get caught when the main body 1 is pulled forward, and the main body 1 can be easily pulled out by removing the connecting tube 4 from the opening edge 2a. It does not slide out and has the effect of reliably resolving the above-mentioned disadvantages of the conventional method.
