Description

[Detailed description of the invention] The present invention relates to the improvement of a so-called hot water outlet, a flow path connector installed in a hot water circuit and on a wall near a hot water supply terminal such as an indoor fan convector. This was devised to prevent minute leaks from electrical outlets or those that occur during connection and disconnection operations from penetrating into the wall surface and damaging the wall.

Hereinafter, the structure and effects of the present invention will be described in detail according to the illustrated embodiment. Fig. 1 shows a sectional view of the embodiment of the present invention, which is embedded in the wall surface so as to be connected to a pipe passing through the wall surface. 1 is the main body of a hot water outlet that is housed and fixed in a box 2 with an open front, and two flow channels 3 and 4 piped from a water heater (not shown) rise within a wall surface 5 and connect to the main body. Connected and fixed to the bottom end of the

A valve device that opens and closes the two flow paths simultaneously is housed in the main body 1, and when a plug 6 is connected to the main body and a lever 7 is rotated to open, a valve device is inserted from the plug 6 through a pair of rubber tubes 8, 9, etc. A flow path is communicated to an end fixture (not shown) such as a fan convector connected to the water heater, and a circulation circuit is formed between the water heater and the end fixture.

For this reason, two independent channels are formed in parallel from the pipes 3 and 4 to the rubber pipes 8 and 9 in the illustrated embodiment.

The box 2 is fixed within the wall surface 5 by appropriate means so that the flat surface on the indoor side and the open end 10 of the box 2 coincide with each other, and the frame 11 attached to the open end is fixed to the box by means such as screws. It is fixed at 2.

A cover plate 12 as shown in FIG. 2 is attached to the frame and is rotatable around both ends near the lower side 13 as fulcrums, and a dish-shaped portion 14 is provided on the back surface of the lower side 13. .

The dish-shaped portion opens upward, and a box 2 is provided above the opening.
A notch 16 provided at the open end of the box is positioned so that water leakage, dew water, etc. that occurs inside the box flows down from the notch 16 to the dish-shaped portion 14.

For this reason, the tongue piece 1 bent from both the upper and lower sides of the box 2
7 and 18 partially protrude, thereby making it possible to attach the frame 11 and the box 2.

Further, as shown in FIG. 3, the dish-shaped portion 14 attached to the frame body 11 is sized to include the entire area of the lower front edge of the box 2.

Furthermore, a tube body 19 is disposed in the center of the lower side 13 which is the front wall of the dish-shaped portion 14, and a tube body 19 is provided at the center thereof, and a mouth portion 20 at the inner end is provided.
is located at the upper part of the tubular body, and the amount of forward protrusion of the tubular body is set appropriately in advance.

On the other hand, the cover plate 12 is opened when the plug 6 is connected;
A through hole 21 is provided near the lower end of the cover plate in correspondence with the tube body 19, and when opened as shown in FIG. 2, the end of the tube body 19 protrudes from the through hole 21 by an appropriate amount.

Further, the back surface of the lid plate 12 faces the front when it is opened, and the back surface has a concave portion 23 surrounded by ribs 22.

In the hot water outlet box of the above-described embodiment, water droplets condensing on the main body 1 or leakage in abnormal situations flow down along this surface and directly or from the bottom surface of the box 2 through the cutout 16 into the dish-shaped part 14. Gather inside.

Since the downstream area of the box 2 where the water droplets and the like flow is sealed in advance to prevent water leakage, the flowing water does not leak to the outside of the box 2.

In addition, the flowing water is stored in the dish-like part 14 at a constant level, that is, until it reaches the mouth 20 at the inner end of the pipe body 19, and does not leak out from the pipe body 19 to the outside.

Under normal usage conditions, leaked water and condensed water are retained in this stored state as they evaporate and escape.

Next, if a small amount of leakage occurs during an abnormality and the amount increases, it will leak into the room through the pipe body 19.
This leaked water is diffused into the back surface of the lid plate 12 and its vaporization is promoted.

In any of the above cases, condensed water, leaked water, etc. do not infiltrate into the wall surface, and damage to the wall surface is prevented.

Further, the structure for this purpose is simplified and the entire structure can be manufactured at low cost.

As described in detail above, the hot water outlet of the present invention includes a main body 1 housed in a box 2 with an open front, a frame body 11 having a cover plate 12 attached to the open end, and a lower column of the frame body. A dish-shaped part 14 is arranged on the back surface of the box 2 to guide leakage water from the box 2 to the dish-shaped part. Plate hole 2
1, so that leakage water generated when connecting a plug, etc., is reliably prevented from entering the wall surface, and damage to the wall surface is prevented, and the structure is designed for this purpose. is simplified.
