JPS5813242Y2 - Hot water boiler operation box - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to an operation box for a hot water boiler.

The operation box of a hot water boiler is normally fixed to the hot water boiler, but in order to enable remote control, it is convenient to attach and detach a remote control case to the operation box fixed to the boiler. .

Conventionally, this type of remote control case has a back plate with a
A hole is provided in which a retaining flap fixed to the operation box is fitted, and the operation box is connected to the operation box.

As a result, the watertightness of the case is impaired, and electrical components such as internal switches may malfunction due to ingress of water droplets or dust.

Furthermore, when the case is attached or detached, the spring goes in and out, causing electrical contact and breakage.

The present invention attempts to solve the above-mentioned drawbacks of the conventional case by separating the interior of the case into an electrical component housing part and a holding part for the operation box.

The present invention will be explained below with reference to examples thereof.

In the figure, 1 is an operation box main body fixed to the exterior plate 2 of the hot water boiler, 3 is a remote control case detachably connected to the box main body, and when performing remote control, the case 3 is removed from the box main body 1. operate the switch, etc.

As shown in FIG. 3, the box body 1 is watertightly attached to the exterior plate 2 of the boiler, and electrical components 4 are housed inside.

The interior of the case 3 is separated into chambers 6 and 7 by a partition wall 5, and one chamber 6 houses an electrical component 8, and a back plate 10 is fixed and sealed via a backing 9. be.

Further, a retaining hole 11 is provided in a portion of the back plate 10 corresponding to the chamber 7, and is adapted to engage with a spring 12 provided at the upper part of the box body 1.

Reference numeral 13 denotes a conductive wire that connects the electrical component 4 of the box body 1 and the electrical component 8 of the case 3, and is drawn out from the box body and the case so as to maintain watertightness.

As described above, in the present invention, the case 3 and the box main body 1 are removably connected through the engagement hole 11 and the spring 2, and the chamber 7 in the case 3 into which the spring 12 is fitted.
Since the chamber 6 is separated from the chamber 6 in which the electrical parts 8 are stored, and the chamber 6 is sealed by the backing 9, the waterproof and dustproof effects of the chamber 6 can be achieved without being affected by the attachment/detachment operation of the case 3. Also, there is no damage to electrical parts due to the spring going in and out.
