At Kinhayabusa, water heaters with a thickness of D and a thick steel plate have become mainstream, as well as water heaters with stainless steel cans that are thinner and more resistant to corrosion. For this reason, current water heaters are
5 13-5 7 3 5 As shown in No. 6, the water supply and drainage pipes to the tank are located in the exterior f that houses the tank.
Since the structure is placed in the lower part of the book, it is necessary to have a space for this part, and there is a drawback that the product must be made very high. In addition, for products that have a bottom plate and water leakage catcher for zero water leakage, the drain port for discharging leakage water is placed at a predetermined height above the drain groove, allowing leakage water to flow smoothly into the drain groove. As such, the bottom plate and water leakage catcher is equipped with legs. For this reason, compared to water heaters that are installed outdoors in general houses and are less susceptible to water leakage, the product height is higher, and when installed indoors or on a balcony, etc. The problem is that it is too expensive to install.

In addition, in order to reduce the installation space of a stove water heater or the like that has the same amount of hot water storage, it is necessary to increase the height, but this is difficult because of the above-mentioned height restrictions.

[Line employment that the invention attempts to solve]

The above-mentioned conventional technology is installed indoors or on a balcony in a condominium, etc.
The product height was not fully considered for large-capacity FO water heaters with a capacity of 2.5 m, or water heaters designed to reduce the installation space, and the range of water heaters that could be installed was narrowed. The purpose of the present invention is to minimize the piping space required for water supply and drainage, to make effective use of the space, and to meet the various conditions for drainage in case of water leakage.
)? The objective is to widen the range of limitations.

[Means to solve the problem]

In order to achieve the above purpose, water and drain ports to the evening tank are provided through the bottom of the bottom plate and water leakage catcher to supply and drain water to the tank.

[Effect]

The present invention has a structure in which the 1D water supply port and drain port portion to the tank penetrates the bottom of the bottom plate and water leakage catcher, so that the through-hole portion of the bottom plate and water leakage catcher of the water supply port and the drain port, which is adjacent to the bottom plate-4L water leakage catcher, Water leakage is prevented by packing, and a sealing material may also be used to ensure this leakage prevention. The piping located upstream from the tank O water supply port and drain port is configured to lead to the side of the product body using the H4C) space provided in the bottom plate and water leakage catcher.

In addition, in the event that water leaks from the tank, the leaked water will be led to the drain through the drain hole and drained away. The tank plate thickness is 0.
8t-1. Ot, water supply port, and drain port are 2.0t to 3.0t.
The tank body and elbow are over 2.5 tons, and the piping is 2 tons, which is nearly 8 times the size of the tank body, so there is no need to worry about water leaking faster than the tank body.

〔Example〕

Hereinafter, one embodiment of the present invention will be explained with reference to FIG. 3 and 8 show longitudinal sectional views of other embodiments.

In FIG. 1, 1 is a tank, 2 is an exterior body, and a tank 1 is housed in this exterior casing.

This tank 1 is supported by a holder l8 and covered with a heat insulating material (not shown). There is a hot water supply port 5 at the top end.
However, a water supply port 6 and a drain port 6a (not shown) are provided at the lower end, respectively. The hot water supply port 5 extends through the exterior straight body 2 and protrudes, and the water supply port 6 and the drain port 6M<
(not shown) passes through the bottom plate/water leakage catcher of the bottom part 11, elbow 9, water supply = #lO, and drain pipe 10a (not shown)
is connected to. The water supply flO is led to water # (not shown), and the other drainage flOa (not shown) is led to a drain, and a drain valve (not shown) is installed at the outlet, which is normally closed. There is one side. On the other hand, #gate 5 communicates with a hot water tap (not shown). Also, inside tank 1,
It is an electric type and is equipped with a heater 4, which heats the water supplied from the water supply pipe 10 into the tank 1 to make it hot water.

The outer device body 2 is fixed to the bottom plate/water receiver l1 via screws. The bottom plate/water leak receiver 1l includes a fixed leg l4 and a drain hole 12, and the fixed leg 14 is fixed to the installation surface 17. will be installed. The drain hole 12 is led to a drainage groove 15 by a drain pipe (shown by a two-dot chain line). Reference numeral 8 denotes an electrical component cover, which is a cover for the heater 4 and the mounting portion of the electric III fan device. The electrical component cover 8 has a packing l6
