Description

[Detailed explanation of the idea] Industrial applications The present invention relates to a water heater.

Conventional configuration and problems thereof Conventionally, as shown in Figs. 2 and 3, water heaters have a space in the front of a rectangular exterior body 4.
An electric heater 3 serving as an electric heating means for the tank 1 and a water supply pipe 7 were provided in one line. However, in this configuration, the water supply pipe 7, the pressure reducing valve 8, and the electrical components 10
and the electric heater 3 are installed in the front space of the tank 1, so if water leaks from the water supply pipe 2, water leaks from the pressure reducing valve 8, or water leaks from the piping connection, the electrical equipment 10, the electric heater 3, etc., and an electrical leakage accident occurred. Note that 2 is a heat insulating material provided between the exterior body 4 and the tank 1.

Purpose of the invention The present invention solves such conventional problems.
The purpose is to prevent electric shock accidents caused by water leaks.

Structure of the Invention In order to achieve this object, the present invention includes a rectangular exterior body, a cylindrical tank provided within the exterior body, and a cylindrical tank that covers the outer periphery of the tank and that partially contacts the inner surface of the body. The tank is equipped with a heat insulating material, and piping is connected to the tank from one of the left and right front corners of the exterior body, and an electric heating means is attached to the tank from the other side.

With this configuration, the piping and electrical components can be installed separately on the left and right sides, with the area where the heat insulating material partially contacts the inner surface of the body as the boundary.
Electrical leakage accidents caused by water leaks can be prevented.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

Note that the same parts as in FIGS. 2 and 3 are given the same numbers.

In Figure 1, the main body of the water heater has water supply piping 7.
is connected, and water is supplied when the stop valve 12 is opened. A hot water supply pipe 5 and a safety valve 14 are connected to the upper part of the main body, and hot water can be automatically drawn from the hot water supply pipe 5 by operating the hot water mixing valve 13.

In FIG. 4, an electric heater 3 and an electrical component 10 are provided in one of the left and right spaces on the front surface of a rectangular exterior body 4, and a drain pipe 6, which is a water component, is provided on the opposite side.
This is a configuration in which a water supply pipe 7 and a pressure reducing valve 8 are provided. The left and right spaces are independent, and can be serviced by removing the front plate 11.

The functions and effects of the above configuration will be explained below. In the conventional example, the water supply pipe 7, which is a water component,
In the event that water leaks from the pressure reducing valve 8, etc., water will splash onto the electric heater 3 and electrical components 10, which are electrical components.
Although an electric leakage accident occurred, in this embodiment, since the water parts and the electric parts are separately housed in the left and right spaces, it is possible to prevent an electric leakage accident due to water leakage.
In addition, since space can be used effectively, the main body can be made more compact and the installation space can be reduced.
By reducing the amount of time needed to transport the main body, it is possible to reduce transportation costs and main body material costs. Additionally, the rear left and right spaces other than the front have the advantage of being able to be used for other purposes.

Effects of the invention As described above, the water heater of the invention provides the following effects.

(1) Since the piping parts and electrical parts are installed separately on the left and right sides of the space in front of the exterior body, even if water leaks from the piping parts, there is no need to worry about water splashing onto the electrical parts, and there is no risk of electrical leakage. It can be prevented.

(2) Since the left and right spaces are used, the outer dimensions of the exterior body can be made smaller and more compact, allowing for smaller installation space. In addition, the amount of packaging required can be reduced, and transportation costs and material costs can also be reduced.

(3) Easy to perform services as they can be performed separately for plumbing and electricity.
