Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to operating means for a water heater.

[0002]

2. Description of the Related Art A water heater is provided with operating means such as a switch for starting and stopping a water supply operation. This operation means is provided with a push button type or swing type switch on the front surface of the water heater main body, and an approach sensor using infrared rays is provided on the tip of a flexible water supply pipe extending from the water heater main body. .

[0003]

However, the conventional operating means is fixed to the water heater, and it has not been considered that the detachability is improved and the operability is freely selected. For this reason, there is a drawback in that it is difficult to move the operation means to a position having excellent operability or to arrange a large number of switch options for the convenience of the user. An object of the present invention is to provide a water heater in which the mounting position can be freely selected and the range of options for operating means can be easily expanded.

[0004]

A water heater of the present invention is a water heater provided with an operating means of a water flow control device for starting and stopping a water supply operation, wherein the operating means is a water heater. Adopted a structure that is detachably attached to the main body. The operation means in the water heater according to claim 2 is a plug detachably attached to an outlet provided at a tip of a lead wire of the water flow control device, and a switch attached to a panel detachably attached to the main body case. , A lead wire connecting the plug and the switch is adopted. A water heater according to a third aspect of the present invention employs a configuration in which the switch is attached to a skirt-shaped panel plate that is detachably attached to a lower portion of the front surface of the water heater.

[0005]

Since the operation means can be easily attached and detached, the mounting position can be changed and the operation position can be freely selected. In addition, it is easy to prepare a wide variety of options.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described based on the embodiments shown in FIGS. Reference numeral 100 denotes a gas instantaneous water heater, which has a water heater main body 1 and a water supply pipe 2 rotatably provided from a fulcrum 21 located below the water heater main body 1. The main body 1 includes a flat box-shaped sheet metal main body case 3 having an open ceiling, and a gas burner and its ignition device, a heat exchanger, and its water flow control device. As shown in FIG. 2, a bottom plate 41 to which a battery case 4, an outlet 12 described later, and the like are attached is fastened to the lower portion of the main body case 3. The body case 3
Is provided with horizontal plate portions 31, 32 on both lower end surfaces thereof,
Rectangular holes 33 and 34 are provided in each of the horizontal plate portions 31 and 32. A skirt-shaped panel plate 5 is detachably attached to the front surface of the lower end of the body case 3.

The panel plate 5 is made of plastic and has a front plate portion 5.
1 and side plate portions 52 and 53. An operating means 6 for starting and stopping the water supply operation is attached to the left side portion of the front plate portion 51. Further, upward wedge-shaped projections 54 and 55 for engagement are provided at the upper ends of the side plate portions 52 and 53, respectively, corresponding to the rectangular holes 33 and 34, respectively, and a fixing piece 56 extending from the front plate portion 51 toward the back is provided. An opening 57 is provided corresponding to the screw hole 42 of the bottom plate 41. The panel plate 5 is steadily fixed to the lower end of the front surface of the main body case 3 by fitting the projections 54 and 55 into the rectangular holes 33 and 34 and fastening the screw holes 42 and the openings 57 with screws. There is. This attachment / detachment and fixing is performed by utilizing the elasticity of plastic. The panel plate 5 may be attached at the middle of the front surface of the main body case 3, and the panel plate 5 may be fixed by a detachable fastener.

The operating means 6 comprises a switch 61 fixed to the panel plate 5, a lead wire 62, and a plug 63 attached to the tip thereof. When the switch 61 is pressed, the water supply operation starts, and when the water flow switch (not shown) detects the water supply operation, the ignition device operates and combustion starts. When the switch 61 is pressed again, the water supply operation is stopped and the combustion is stopped at the same time. The plug 63 is detachably connected to the outlet 12 attached to the tip of the lead wire 11 drawn out from the water flow controller of the water heater body 1. An LED provided on the side of the switch 61
Reference numeral 64 denotes a battery voltage confirmation LED that can be turned on when the voltage of the battery is equal to or higher than a predetermined voltage.

By making the operating means 6 attachable / detachable to / from the main body case 3 and the water flow control device, the following effects are obtained. (A) It is easy to optionally set the skirt panel plate 5 having the switch 61 on the right side or another position as shown in FIG. 3 according to the set position of the water heater. (B) As shown in FIG. 4, it is possible to easily connect the foot-operated switch 7 or other operating means (for example, an infrared sensor installed at the tip of the water supply pipe 2). (C) By attaching the detachable panel plate 5 to the lower end of the front surface of the main body case 3, the connection members for the water supply pipe 2, the water pipe, and the gas pipe located at the lower part of the main body can be hidden, and the appearance is good. You can

When operating means is connected to the outside of the water heater body 1 as shown in FIG. 4, the panel plate 5 may or may not include operating means. Also plug 63
The structure can be freely selected as long as the socket and the outlet 12 can be easily attached and detached.
