By installing a water stop valve or a check valve in the middle of the drainage pipe, there is no need for a water storage tank in the middle of the drainage passage, and wastewater and water tanks discharged from the bath, kitchen, basin, etc. Can be distributed and supplied as wash water for washing toilets, washing water and other fire extinguishing water.

Further, the drainage supply device of the present invention is arranged in the middle of the submersible pump for pumping, which is arranged outside the water collecting tank and connected to the suction tank, and one end is connected to the discharge part of the submersible pump. A discharge pipe having an air vent valve that branches in two directions and operates via a float on one side of the other end, and a drain outlet combined with a check valve on the other end of the other end; and discharge of the discharge pipe An air vent hole is provided in the middle of the part and the bifurcated part to communicate with the suction part of the pump so that the pump can be prevented from idling.

Furthermore, the drainage supply device of the present invention has a submersible pump placed in the water collection tank, and one end is connected to the discharge part of the wastewater sucked in the water collection tank, and a water stop valve is provided on one side branched in the middle. The other end of the other end communicates with the suction part of the pump as a discharge pipe having a check valve so that the pump can be prevented from idling.

Also, the drainage supply device of the present invention has a float sensor (low tank sensor) that detects the water level of drainage in a storage tank of a supply destination for storing drainage supplied by the pump in a drain pipe connected to the fire hydrant. And the pump can be stopped via a float sensor when the sensor detects that the amount of water stored in the water storage tank exceeds a predetermined amount. Thereby, the overflow of the water tank of a supply destination can be prevented.

Embodiments of the present invention will be described below based on the embodiments shown in the drawings.

FIG. 1 is a block diagram showing an embodiment of a wastewater supply apparatus according to the present invention. Figure 2 is a schematic explanatory view showing a state of attaching the hydrant midway of the drain pipe in FIG. 1, FIG. 3 is a side view showing the details of the on-off changeover switch of FIG definitive manual water pump.

As shown in FIG. 1 , in this embodiment, the pump forcing device 1 with an air vent valve 2 in which the pump forcing device 1 is disposed outside the bathtub 8 and one end of the drain pipe 10 sends the water in the bathtub 8 to the water destination. 1 is connected to the discharge unit. Further, the drain pipe 10 is branched into two in the middle, and a water stop valve (solenoid valve) 3 is attached to one A pipe, and a check valve 4 and a fire hydrant 5 are attached to the other B pipe. In addition, the water destination of the A pipe is connected to the washing machine 7, and the water destination of the B pipe is connected to the flush tank 6 a of the toilet 6. Needless to say, the submersible pump may be mounted directly in the bathtub 8 as shown by a broken line in FIG. Furthermore, in this embodiment, as shown in FIG. 2 , a fire hydrant 5 is attached in the middle of the B pipe of the drain pipe 10, and the fire retardant (fire-extinguishing nozzle and hose) 5b can be attached to and detached from the fire hydrant 5 with one touch. . Normally, the remaining water in the bath is automatically switched and distributed to the washing water and the washing water in the flush toilet via the float sensor 9, but in the event of an emergency such as a fire, it is shown in FIG. It is also possible to operate the pump forcing device by switching the on-off changeover switch 5a of the submersible pump to the manual type.

Next, with reference to FIG 1-3 the operation of the main components of the waste water supply device of the present invention. In some cases, the drainage supply device directly puts a pump into a water collection tank or a bathtub, or there is a case where the submersible pump for pumping is arranged outside the water collection tank to draw water from the water collection tank or bathtub.

About the stop valve 3: When pumping up directly from a water collection tank bathtub, you must use the air vent valve 2 or the air stop valve 2b.

  When the pump forcing device 1 is used from the water collection tank bathtub, the air vent valve 2 and the air stop valve 2b must be used as shown in FIG.

When the water stop valve (solenoid valve) 3 is used, it becomes fully automatic when a power source of a pump (not shown) built in the washing machine 7 is used. When the manual water stop valve 3 is used, the manual water stop valve 3 must be opened and closed only when the washing machine 7 is used. When the washing machine 7 is not automatic (when the pump is not incorporated), the water stop valve 3 is necessary for both the washing machine 7 and the toilet 6. In this case, the check valve 4 is not necessary.

  Furthermore, when the washing machine 7 and the toilet 6 are used at the same time, the pump for pumping the toilet and the pump built in the washing machine 7 operate at the same time, so that the drain pipe 10 is divided into two pipes A and B. Change the inner diameter to larger or smaller (resistance) and adjust the amount of water.

When the washing machine 7 is not automatic, only the pumping pump 8 in the bathtub is operated, so the water stop valve 3 is opened and closed and used separately for toilets and washing.

  Further, the check valve 4 on the toilet side is closed so that air is not drawn into the pipe when a pump built in the washing machine 7 is operated. The water pressure or the pressure is always applied by the spring, and when the pumping pump is operated, the check valve 4 is pushed up and the water flows to the toilet 6.

  The one-touch fire arrester shown in FIG. 2 is a device that can be used in an emergency such as a disaster or housework through the fire hydrant 5 in the middle of the B pipe of the drain pipe 10 of FIG. It goes without saying that this device can be connected to a reused water device or tap water (water pipe).

When the cord of the water level (float) 9 sensor attached to a low tank (not shown) (which may be either + or-) is connected to the handle of the two-way valve 5A shown in FIG. 2, and the handle is turned, the enlarged view is shown in FIG. As such, the on-off switch of the submersible pump is adjusted so that it is always ON or OFF.

The on-off change-over switch shown in FIG. 3 is an example in which a spare switch for coping with the electric galling of the switch is also provided.

When using a water pipe (not shown), it is only necessary to turn the handle by hand.
The hose of the one-touch fire protector 5b (fire-extinguishing nozzle and hose) determines the inner diameter strength according to the pump or water pressure.

The one-touch portion of the fire protection device 5b is easily inserted into the fire hydrant 5.
In addition, when the fire hydrant 5 is removed from the one-touch portion, it is devised so that it can be easily removed by holding the fastener.

  As mentioned above, although the Example of this invention was described, this invention is not limited to this Example.
