JPS6035010Y2 - Control box mounting device for water heater - Google Patents

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a control box mounting device for a water heater.

(Conventional technology) Conventionally, in order to protect the control box that controls the opening and closing of gas valves, etc. from thermal effects in water heaters, the inside of the main body is divided into upper and lower parts by partition plates, with the upper part serving as the combustion chamber and the lower part serving as the control chamber. The control box was attached to the wall of this control room with screws, etc.

(Problem that the invention aims to solve) However, in such conventional examples, when the water heater is installed outdoors on the ground or floor, the control room is formed at the bottom of the main unit, so it is difficult to install and remove the control box. The work must be done close to the installation surface, which has poor work efficiency, and depending on the installation site, the main body may have to be installed with the work opening of the main body close to the wall of the house. However, it is even more difficult to install and remove the control box at such installation sites.

(Means for Solving the Problems) The present invention is an attempt to solve the above problems, and the structure in which the inside of the main body is divided vertically into a combustion chamber and a control chamber by a partition plate is the same as the conventional one. The left and right sides of the longitudinal side of the main body are opened, and a cover is provided that can open and close the left and right openings respectively.

Furthermore, the partition plate is provided with rails on its lower surface with both ends facing the openings on the left and right sides, and the control box is provided with a hanging fitting that slides on the rails.

(Function) To remove the control box, open the cover on either the left or right side, pull out the control box inside the control room from the opening above, and the hanging bracket will slide on the rail to easily remove the control box. It can be taken out of the main body.

Conversely, the control box can be easily installed by inserting the hanging fitting onto the rail through the above opening.

(Example) Reference numeral 1 denotes a water heater main body, in which a combustion chamber 3 having a heat exchanger 2 in the upper part of the main body and a control chamber 6 having a control box 5 for controlling the opening and closing of a gas valve 4 in the lower part are partitioned by a partition plate 7. It's a formality.

8 is a water inlet, 9 is a hot water outlet, 10 is a gas burner, and 11 is a rainproof plate.

The left and right sides of the water heater main body 1 on the longitudinal side are open, and each opening can be opened and closed by a cover 12.

13 is a screw for installation.

14 is a cross section of the partition plate 7 attached to the lower surface with both ends facing the openings of the left and right sides! There are mold-shaped rails, two of which form a pair.

Reference numeral 15 denotes a hanging metal fitting attached to the control box 5, which has an engaging piece 16 placed on and engaged with the rail 14, and is configured to slide in the lateral direction of the partition plate 7, that is, in the opening direction.

Reference numeral 17 is a metal fitting for removing and stopping.

In the above configuration, when assembling, the control box 5 may be inserted from either one of the longitudinal left and right sides of the water heater body 1, and the post-fitting fittings 17 suspended from the rail 14 may be attached.

Since the control box 5 is designed to slide in the lateral direction of the partition plate 7, it can be attached from the opening side of the instrument.

When installing on-site after the equipment is shipped, the main body 1 is installed stationary along the wall of the building in order to minimize the installation space. Since the cover 12 is provided, even if the -blade side is in close contact with a wall surface, the control box 5 can be easily attached and detached from the other side.

In addition, since the control box 5 is attached below the partition plate 7 via the hanging metal fittings 15, it is less susceptible to the thermal influence of the combustion chamber 3 and can maintain good operability.

(Effects of the invention) As described above, the invention protects the control box that controls the opening and closing of gas valves, etc. from thermal effects,
Moreover, it was possible to provide a device that can be used to easily attach, detach, and assemble the control box at any installation site.
