DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof pan constituting a floor of a bathroom unit provided with a drainage pumping device.

[0002]

2. Description of the Related Art Conventionally, a drainage pumping device is sometimes used to discharge drainage from a bathroom to the outside well, and this drainage pumping device has a built-in pump inside. By using, the drainage pipe can be made narrower than the conventional natural drainage, and the drainage can be reliably discharged to the outside even in the case of a reverse slope. However, in the case of the waterproof pan constituting the floor surface of the bathroom unit, it is difficult to properly supply the drainage on the waterproof pan to the drainage pumping device, and the conventional waterproof pan cannot exhibit a good drainage function. Was something.

[0003]

SUMMARY OF THE INVENTION The present invention has been devised in view of the above-mentioned conventional problems, and is intended to supply drainage to a drainage pumping device satisfactorily and discharge the drainage to the outside by the drainage pumping device. The purpose of the present invention is to provide a waterproof pan that can be washed, and the gist of this is that a waterproof pan for a bathroom unit equipped with a drainage pumping device with a built-in pump to pump drainage has a concave basin on the washing side. It is the washing of upper該桝portion

A drainage tray that can be fitted is installed.

[0004]

[Function] The waterproof pan constituting the bathroom unit is formed with a concave-shaped basin, and a drainage tray is fitted into the basin, so that the drainage from the washing area on the waterproof pan is reliably received by the drainage pan. The drainage pumping device can reliably discharge drainage to the outside by driving the internal pump.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a waterproof pan 1 constituting a floor surface of a bathroom unit. The waterproof pan 1 is formed of FRP. And is formed in a state partitioned by the
Is integrally formed with four foot plate portions 5, 5, 5, 5 protruding upward. The legs of the bathtub are placed on the foot plate portions 5, 5, 5, 5. A bathtub can be set up.
In addition, a storage recess 6 is formed in a concave shape on the side of the bathtub mounting portion 2.
Can be placed.

Further, the boundary projection 4 on the storage recess 6 side.
Is formed with a cutout portion 4a penetrating to the washing place 3 side, and a concave cell portion 7 is formed on the washing place 3 side of the cutout portion 4a. As shown in the enlarged view of FIG.
An inner horizontal portion 8 having a horizontal surface is formed on the outer periphery of the basin portion 7, and a plurality of screw holes 8a, 8
a is formed. Outside the inner horizontal part 8, an inner vertical part 9 which rises vertically is formed.
Further, an outer horizontal portion 10 having a horizontal surface is formed at an upper end of the inner vertical portion 9, and an outer vertical portion 11 is formed vertically at an outer end of the outer horizontal portion 10.
Are integrated with the boundary projection 4. In addition, a step portion 12 is formed at a position lower than the upper end of the boundary protrusion 4 at the upper end on the boundary protrusion 4 side of the outer periphery of the square portion 7.

[0007] The drainage tray 13 can be fitted into the box 7 formed as described above from above.
A perforated plate 16 having a large number of through holes 16a can be attached to the upper surface of the drainage tray 13 in a cover-like shape. The drain tray 13 includes a tray body 13a.
And a drain port 13b opened to the rear thereof, and a protruding pipe 13c integrally formed in a protruding manner on the back side of the drain port 13b.
And a flange 13d protruding horizontally on the outer periphery of the tray main body 13a. A plurality of screw holes 13e are formed through the flange 13d.

In the drain tray 13, a flange 13d is placed on the inner horizontal portion 8, screws 15 are respectively inserted into screw holes 13e from above through a washer 14, and screws 15 are screwed into the inner horizontal portion 8. By screwing into the hole 8a, the drain tray 13 can be mounted on the basin 7. In this mounted state, the tray body 13a of the drain tray 13 is mounted.
Is installed at a lower position than the surface of the washing room 3 and the washing room 3
All the wastewater inside can be collected in this wastewater receiving tray 13. In addition, the perforated plate 16 can be mounted on the outer horizontal portion 10, and the upper end piece 16 b of the perforated plate 16 is placed on the step portion 12 so as to be substantially flush with the upper end surface of the boundary projection 4. Become.

Accordingly, when the drain tray 13 is covered with the perforated plate 16, the perforated plate 16 is flush with the boundary projection 4 and substantially flush with the floor surface of the washing place 3. It can be mounted with a customized appearance. In such an attached state, the projecting pipe 13c of the drainage tray 13 projects toward the storage recess 6 through the notch 4a, so that the drainage pumping device 18 housed in the storage recess 6 and the projection pipe 13c
By properly connecting c, the drainage collected by the drainage tray 13 can be satisfactorily sent to the drainage pumping device 18.

The drainage pumping device 18 has a structure as shown in FIG. 3, and a pump 20 is built in a case body 19, and the pump 20 is turned on by a water level switch.
The pump is turned off, and an outlet pipe 21 is connected to the pump 20, and the outlet pipe 21 is connected to the outside of the bathroom via a pipe or the like. Also,
A bathtub drainage inlet pipe 22 and a washing-side drainage inlet pipe 23 project from the case body 19.
3c can be connected via a pipe or the like.

The bathtub drainage inlet pipe 22 is connected through a pipe or the like to a drain plug of the bathtub mounted on the bathtub mounting portion 2. When the drainage flows into the drainage pumping device 18 through the bathtub drainage inlet pipe 22 and the washing side drainage inlet pipe 23, the internal water level switch detects the water level and activates the pump 20. The water is reliably discharged to the outside through the pipe 21, and the drainage can be pressure-fed by a thin pipe, so that the drainage can be reliably discharged to the outside without any problem even when a reverse gradient is formed. In addition, even when the waterproof pan 1 is installed at a low position, the drainage can be reliably discharged to the outside by using such a drainage pumping device 18.

FIG. 4 is a perspective view of a main part showing a modification of the waterproof pan 1. In FIG. 4, a counter section 25 is formed on the washing station 3 side. Bend to the side and measure 7 on the side of counter 25
Are formed in a concave shape, and an inner horizontal portion 8 to which a drainage tray 13 similar to that shown in FIG. Are formed.

Also in such a configuration, the drainage tray 13 attached to the basin 7 can collect the wastewater from the washing place 3 satisfactorily and send it to the drainage pressure feeding device 18.
In this example, the drainage pumping device 18 is stored in the storage recess 6, but the drainage pumping device 18 may be stored below the counter 25.
8 may be installed outside the waterproof pan 1.
