A discharge pipe E passing through the frame body 28 is provided at the lower end of the frame body 28.

In this device, water leaking from the connection part of the valve body 1 and condensed water that forms on the valve body 1 drips onto the lower wall 16 of the box 2, and then is stored in the saucer 22, and is passed through the discharge pipe E to the indoor side. Therefore, the above-mentioned water leakage and condensation water are significantly less likely to enter the wall surface 3.

However, in this prior example, when the water leakage or condensation water drips from the bottom wall 16 of the box 2 to the saucer 22, a part of it flows along the back surface of the bottom wall 16 of the box 2 and enters the wall surface. be.

This is because the amount of water leakage and condensation is very small.
This is because the water discharged from the center of the front edge of the lower wall 16 moves horizontally to the back side of the lower wall 16 of the box 2 in the installed position due to its surface tension.

(Technical Problem) The present invention has been made in view of the above-mentioned points. The valve body 1 is provided in a box 2 opened to the indoor side, and the terminal equipment is connected from the open end side of the box 2. The opening of the box 2 is opened and closed by attaching the cover plate 31 supported by the frame 28 to the surface of the wall 3, and the front of the lower wall 16 of the box 2 is connected. In a device in which leakage water or condensation water is discharged from the edge into a saucer 22 provided below the lower wall 16, the technical problem is to reliably prevent water leakage from entering the wall surface 3. shall be.

(Technical Means) The technical means of the present invention taken to solve the above technical problem are as follows: A rising part 18 is provided in the entire front edge of the lower wall 16, and a notch is formed in the middle of this rising part 18. 19 and is provided with a tongue piece 23 that hangs down from the front edge of the lower wall 16 or the vicinity thereof, and this tongue piece 23
The arrangement area is at least the entire area below the notch 19, and the size of the saucer 22 is set larger than the area below the notch 19.

(Operation) The above technical means of the present invention operates as follows.

Water leakage and condensation from the valve body 1 should be removed from the lower wall 16.
After being collected on the upper surface, water drips from the notch 19 into the saucer 22. In this drip area, there is a tongue piece 23 that hangs downward from the back surface of the lower wall 16. and drips onto the saucer 22.

Although the back surface of the lower wall 16 is in a horizontal state, the tongue piece 23
Since the lower end of is located below the back surface of the lower wall 16, the discharged water does not move to the back surface side of the lower wall 16.

(Effects) Since the present invention has the above configuration, it has the following unique effects.

Since the discharged water does not move to the back side of the lower wall 16, all of this discharged water reliably drips onto the saucer 22, and water can be reliably prevented from entering the wall surface 3.

(Example) Hereinafter, details of an example of the present invention will be described based on the drawings.

FIG. 1 shows a sectional view of the installed state of the box valve according to the embodiment of the present invention.
The box is embedded in the wall 3, and the open part opens toward the indoor side. A pair of flow passages 4, 4 are formed within the valve body 1, and a pair of hot water supply pipes 5, 5 rising within the wall 3 are connected to a pair of connecting pipes 6, 6 projecting downward from the box 2. Note that this figure is a cross section of one channel side, and channels having the same configuration are arranged in parallel. This also applies to valve devices and the like described below.

A set of valve devices is inserted into each flow path, and to explain one of them as an example, the valve device consists of a main valve 7 and a sub-valve 8, and these valves are interlocked with each other. When the valve shaft 10 of the main valve 7 protruding into the connection port 9 provided at the upper front of the valve body 1 is pushed in, the main valve opens and the sub-valve 8 also opens.

The connecting tube 12 of the plug 11 corresponds to the connecting port 9, and when the connecting tube 12 is inserted into the connecting port 9,
When the normally closed valve body 13 inserted into the flow path of the plug 11 pushes the valve shaft 10, the normally closed valve body 13 also opens. The plug 11 also has a pair of flow passages arranged in parallel and have the same configuration, and the pair of connection tubes 12, 12 of the plug 11 are connected to the integral connection port 9 on the valve body side.
9 at the same time, thereby communicating the two channels. Each flow path of the plug 11 is connected to the end connector 14 of the fan convector, and by inserting the plug 11 described above, circulation returns from one flow path 5 to the other flow path 5 via the end connector 14. The circuit is connected.

Reference numeral 15 is a stopper that closes the pair of connection ports 9, 9 that open at the upper front of the valve body 1 when the end is not in use.

A pipe connection part 17 protrudes downward from the bottom wall 16 of the box 2 in an airtight state, but a sealing means is provided between the outer periphery of the pipe connection part and the bottom wall 16, so that this part is not airtight. It is maintained. Further, a rising portion 18 is provided at the front edge of the lower wall 16, and a notch 1 is provided at the center of the rising portion, as shown in FIG.
9, and the cutout portions are formed on both side walls 2 of the box 2.
0 and 21, and furthermore, a tongue piece 2 is provided in an appropriate range of the front edge of the lower wall 16.
3 hangs down and faces inside the saucer 22.

The saucer 22 is provided integrally with or separately from a display plate 25 that closes the open end of the box 2 and has an opening 24 corresponding to the connection ports 9, 9, and a lead-out passage 27 is provided on the front wall 26 of the saucer. is provided, and the lead-out path is made to protrude from a through hole 29 bored at the center of the lower side of the frame body 28.

The frame 28 has an opening corresponding to the front of the box 2, and the frame around the opening corresponds to the front of the box 2.
The frame body 2
A cover plate 31 is rotatably attached in a manner included in 8. In the illustrated embodiment, the upper end is the fulcrum, and the cover plate 31
is rotated upward and released.

Further, a tongue piece 32 protrudes below the through hole 29 on the lower side of the frame 28, and its tip protrudes from the indoor side wall surface of the wall 3 by an appropriate amount.

In the case of the above-mentioned embodiment, all of the small amount of water leaking from the valve body 1 and condensation water in the event of an abnormality drips into the lower wall 16 of the box 2, and flows from the notch 19 in the center of the rising part 18 of the front edge to the receiving tray. Drop into 22. At this time, since the tongue piece 23 hangs down from the back surface of the notch 19, the stored water overflowing from the notch drips into the saucer only from the tongue piece without running down the back surface of the lower wall 16. , these condensed water and the like do not infiltrate into the wall 3 at this portion.

Next, the water stored in the saucer 22 is transferred to its front wall 26.
It passes through the lower side of the frame 28 from the outlet path 27 and evaporates or drips from the tongue piece 32. Therefore, even in this route, there is no risk of condensed water or the like intruding into the wall 3.

In addition, since the amount dropped in this case is extremely small,
Most of it remains stored in the tray 22 and leaks out from the outlet path 27 in the event of an abnormality.
