Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mounting device for an indicator lamp in an electric water heater or the like.

Conventional Structure and Problems Conventionally, this type of indicator lamp mounting device has an indicator lamp 22 on an insulating plate 21, and a voltage dividing resistor connected in series with the indicator lamp 22, as shown in FIGS. 23 and a lead wire 29a for connection with other electrical components.

If 29b and 29c are soldered and screwed onto the boss 26 provided on the inner surface of the display board 24, the display board 2
4 is provided with a through hole 26 at a position corresponding to the indicator lamp 22, a light-transmissive lamp window 27 is positioned on the outer surface of the hole 26, and the display plate 24 is attached to the display plate 24 by bending a nail or the like. The rung window 27 was clamped and fixed by a mounting plate 28 having a through hole for allowing the lamp window 27 to be viewed from the outside.

In this conventional indicator lamp mounting device, the indicator lamp 2
2 to the insulating plate 21, the lead wire 22a of the indicator lamp 22 is usually made of soft copper wire with a diameter of 1 mm or less, and it is difficult to attach it correctly to the position corresponding to the through hole 26 of the indicator plate 24. It is difficult to work with, and misalignment inevitably occurs. For this reason, when the indicator lamp 22 is turned on, the light passing through the lamp window 27 has a drawback that its brightness varies depending on the location of the lamp window. In addition, electric water heaters and the like where water tends to splash onto the indicator lamp section have the disadvantage that water enters the lamp wiring section, causing insulation deterioration and lighting failure. Furthermore, in this configuration, the display lamp portion is attached so as to be integrated with the display board, and the display board also needs to be handled during wiring work, which requires complicated work.

OBJECTS OF THE INVENTION One object of the present invention is to easily and reliably attach an indicator lamp.

Structure of the Invention The present invention provides a display plate having a plurality of display holes, a lamp window made of a transparent material and having a flange portion, a substantially box-shaped holder having a through hole corresponding to the display hole, and a fitting for positioning. It consists of an insulating plate with a lamp attached to the hole, a lamp window is engaged with the display hole of the display plate, the flange part is held between the display plate and the body, and the insulating plate with the lamp attached is inserted into the claw part of the holder. The hook provided at one end of the holder is engaged with the corresponding retaining hole, the slit claw provided at the other end is engaged and locked, and the holder is attached to the body. The aim is to achieve the intended purpose.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 1 to 4, 1 is an electric water heater main body, 2 is a cylindrical body made of sheet metal, etc., and a display plate 3 made of synthetic resin is attached to the front side. This display board 3
A plurality of display holes 3a are bored in the lower part of the display hole 3a, and bosses 3b for temporarily fixing the lamp window 4 are provided near the display holes 3a in correspondence with the positioning holes 4a of the lamp part. 5 is holder 6
an insulating plate inserted into the inside of the display hole 3 of the display board 3;
A positioning fitting hole 5a is drilled at a position corresponding to a,
A langua for indicating that the water is boiling and a lamp 8 for indicating the temperature keeping are fitted into the fitting hole 6a in a slightly buried state, and are held in position. The insulating plate 5 is held by claws 6a provided on the inner wall of a substantially box-shaped holder 6 made of synthetic resin. The lead wires 7a, 7b, 8a, 8b led out from the lamp 7.8 are soldered 9a, 9b, 9c through the insulating plate 5 as shown in FIG.

Langua for 9d and 9e, p for guarantee of 8 (anti-10°11
It is connected with the said half IJJ9a, 9+.

9C has leads of $312a, 12b, respectively.
1 and 2a are connected at the same time, and the notch capital 6b of the holder 6
It is connected to other electrical parts at a distance h''.

Further, the holder 6 has a through hole 6C at a position corresponding to the display hole 3a of the display board 3, and the lamp 7.8 is mounted so as to be slightly buried therein. To attach the holder 6 and the body 2, align the pair of hooks 6e with the notch holes 2a of the body 2, hook them, and position the holder 6.
7) Insert the sulin) ef provided on the lamp part into the claw 2b of the body and bend the claw to fix it. 2C is the display hole 3
This is a notch provided to correspond to a. The lamp window 4 is engaged with the display hole 3a of the display board 3, and the flange portion 4b
is held between the display board 3 and the body 2. When both the lamp window 4 and the holder 6 are assembled, the lamp window 4
The lamp 7.8 is fixed at a position corresponding to .

Effects of the Invention As is clear from the above explanation, according to the present invention, the holder of the Rambuo JIM (te JkJ) is independent as one unit, and when disassembling and reassembling the conventional lamp part for repair etc., the display board is Although disassembly and assembly were required, in the present invention, the purpose can be easily achieved by handling a relatively small part called a holder.Furthermore, the installation is done by hooking and pawing, and it is easy to tighten with a screwdriver. No work is required, and ease of assembly and service is greatly improved.Also, since the indicator lamps were conventionally attached directly to the display board, if the display lamp is located close to the heating element 13, the entire display board should be moved to the high side. This required a thermoplastic and was expensive, but in the present invention, the holder is independent, so the parts are small and inexpensive.

Furthermore, since the conductive part of the lamp is located inside the body and surrounded by the holder, there is also an effect that water is prevented from entering from the display panel part when cleaning the main body, and there is no risk of insulation deterioration.
