Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a device for supplying and draining water to equipment such as washing machines that require piping for supply and drainage pipes.

Conventional technology As a means for supplying water to equipment such as washing machines,
There is one in which an attachment is attached to the outlet of a water faucet, and water is supplied through a water supply hose connected to this attachment (for example, Japanese Utility Model Publication No. 55-145571). On the other hand, as a means for discharging wastewater from equipment into a drain pipe, there is a method in which a drainage trap is attached to a waterproof pan, and the drainage hose of the equipment is attached to this drainage trap (for example, Publication No. 91772).

Taking the washing machine 1 as an example, conventional piping equipment includes a water supply pipe 2 and a drain pipe 3 as shown in FIG. That is, the water supply pipe 2 is arranged between the wall materials 5 and 5 on both sides of the wall body 4, and the water supply pipe 2
A water tap 6 attached to the washing machine 1 penetrates the wall material 5 located at the upper end of the washing machine 1 and protrudes from the wall surface 7, while a water tap 6 attached to the waterproof pan 9 provided on the floor surface 8 for installing the washing machine 1 In this case, a drain trap 10 was installed through a floorboard 11 and connected to a drain pipe 3 arranged under the floor 12. A water supply hose 14 is attached to the faucet 13 of the water supply faucet 6, and a drain trap 1
A drain hose 16 is attached to the water inlet 15 of the 0, and while the water supply from the water supply pipe 2 is interrupted by operating the hydrant 6, water that overflows or is no longer needed after washing is removed. The waste water is allowed to flow out through a drain trap 10 into a drain pipe 3.

Problems that the invention aims to solve: In a structure where the water supply tap and drain trap are placed in separate locations, the water supply pipe and the drain pipe must be installed separately, and as a result, waterproofing is required. Construction work had to be done for each water supply and drainage system, which caused the problem of increased construction costs. Moreover, the water supply system and drainage system were separated into separate locations, making maintenance and management difficult.

Means for Solving the Problems The present invention has been made to solve such problems, and the opening 18 is formed at one place on the floor surface 19 and the waterproof lid 21 is removably attached. In addition, a water tap 26 connected to a water supply pipe 36 and a drain trap 34 also connected to a drain pipe 46 are attached to the waterproof lid 21 by penetrating the front and back thereof.

Embodiment FIG. 1 is a perspective view showing an embodiment of the present invention. In the figure, reference numeral 18 denotes an approximately rectangular opening in the floor surface 19. A washing machine 20 is placed directly on the floor 19 along the longitudinal direction of the opening 18. 21 is a waterproof lid formed into a rectangle to match the opening 18, and as shown in FIG. It is adapted to be locked to the portion 25. It is desirable that the floor plate 24 be fixed to the waterproof lid 21 by appropriate means so that it can be removed.

26 is a water tap attached to one end of the waterproof lid 21 in the longitudinal direction. Faucet body 2
A cylindrical screw portion 28 of No. 7 penetrates through the waterproof lid 21 and protrudes to the back surface side, and is fixed with a nut 29. A water supply pipe 30 is connected to the tip of this cylindrical screw portion 28 by a cap nut 31. Waterproof lid 21
A water spout 32 of the faucet 26 is provided on the surface side of the faucet 26 so as to protrude obliquely upward from the side wall portion of the faucet body 27 . The water supply hose 3 is connected to this water spout 32.
3 are now connected.

On the other hand, 34 is a drainage trap attached to the other end side of the waterproof lid 21. The upper end of a trap body 36 is fixed to a support tube 35 that penetrates through the waterproof lid 21 and protrudes toward the back side. 37 is the support tube 3
This is a gasket interposed between the flange portion 35a of No. 5 and the waterproof lid 21. A drain hose 40 is attached to a water receiving port 39 at the upper end of the drain hose receiver 38 on the upper side of the support tube 35 .
Note that the water receiving port 39 is connected to the drain port 41 of the washing machine 20.
It is desirable to place it further down. On the other hand, a drain pipe 42 that penetrates the bottom of the trap body 36 from inside to outside.
A deodorizing lid 43 resembling an upside-down bowl is installed at the upper end so as to cover it. 44,44
... are water holes provided in the lower end side wall portion 43a of the deodorizing lid 43. 45 indicates a water sealing part. A drain pipe 46 is connected to the lower end of the drain pipe 42.

Reference numerals 47, 47, . . . designate drain holes for draining water that somehow leaks from the joints of the constituent members and falls onto the waterproof lid 21. 48 is
This is a main valve provided in the middle of the water supply pipe 30.

In this way, water transmitted through the water supply pipe 30 is supplied to the washing machine 20 via the water tap 26, and after use, is drained into the drain pipe 46 via the drain trap 34.

Effects of the invention The present invention has the above-mentioned configuration. In addition to forming an opening in one place on the floor surface and removably attaching the waterproof lid, the invention also has a water tap connected to the water supply pipe and a water tap connected to the drain pipe. Since this feature is characterized in that the water supply pipe and drain pipe are installed in one place, the water supply pipe and the drain pipe can be installed in one place, instead of the conventional method of installing them in two places. Since waterproofing work can be done in one place, this contributes to cost reduction.
In particular, since the opening is slightly larger after the waterproof lid is removed, the opening can also be used as an underfloor inspection port, making maintenance and management easier.
