Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The water storage tank (10) is connected to a drain of a public washstand (1) through a drainage pipe (3). The water storage tank (10) stores the water drained from the public washstand (1), and the storage capacity is determined according to the user's choice. The water storage tank (10) is composed of a tank body (11) having an opened top and a top plate (12) in the form of a lid for sealing the upper opening of the tank body. The side wall of the tank main body 11 is provided with a water supply port 15 for receiving a constant water and a discharge port 16 for allowing water to flow out.

The purifier is installed in the water storage tank (10) to purify the water supplied from the common washstand (1). The purifier may include a first filter (20) and a second filter (30). Hereinafter, the purifier will be described with further reference to Fig.

As shown in FIGS. 5 and 6, the purification unit including the first filter and the second filter has a structure in which wastewater is purified by passing through gravity, but the wastewater is passed through a pump I can do it. The first filter (20) is for filtering large foreign matters such as hair, soap pieces and the like from the water supplied from the drain of the common washstand (1). The first filter 20 may include a water collecting tube 21 having a drain hole at the bottom and a metal filter 22 placed on the bottom of the water collecting tube 21. The water collecting tube 21 is fitted in the first filter receiving groove 14 which is recessed in the upper plate 12 of the water storage tank 10. The receptacle (21) is fitted in the first filter seat (14) so that the manager can easily lift it by hand. The water that has passed through the first filter (20) flows into the second filter (30) installed in the downward direction.

6, the second filter 30 includes a filter casing 31 mounted on the bottom surface of the top plate 12 of the water storage tank so as to be suspended from the bottom of the filter casing 31, And contains activated carbon 32 in the form of granules. Nonwoven fabrics 34 and 35 are provided on the outlet and inlet sides of the filter casing 31 to prevent the activated carbon 32 from flowing out of the filter casing 31 and to enhance the purification effect of the wastewater. The shape of the filter casing 31 is composed of a large diameter portion 31a having a large flat area at its lower portion and a small diameter portion 31b having a flat area relatively narrower than the large diameter portion 31a at its upper portion. This configuration is for allowing the water to be quickly purified and put into the internal space S of the water storage tank 10. [ The activated carbon 32 of the second filter 30 is used to neutralize the odor generated in the synthetic detergent or the like by removing the turbidity of the water.

The water supply unit separately supplies the purified water inside the water storage tank 10 to the toilet bowl 2 through the water supply pipe 4 for cleaning the toilet bowl 2 in the toilet. The water supply section includes a water supply pipe 4, a main pump 40, a water drop detection section, and a control section. The water supply pipe 4 connects the water storage tank 10 and each toilet bowl 2 in series or in parallel so that water in the water storage tank 10 is supplied to each toilet bowl. 1, each toilet 2 is connected in parallel.

The main pump 40 pumps the water stored in the water storage tank 10 and supplies the water to each toilet 2 of the toilet. The main pump 40 may be installed inside or attached to the outside of the water storage tank 10. The main pump 40 is driven by a signal from the control unit. The water drop detection unit determines whether the toilet user operates the water drop valve 5 installed in the toilet bowl 2 in the toilet and applies a signal to the control unit.

A magnet switch (not shown) may be installed in the water drop valve lever 2a to detect a change in the physical position of the water drop valve 5. Therefore, when the water lowering valve lever 2a is operated, the water lowering valve 5 is opened, and at the same time, a signal is applied to the main pump 40 so that the water in the water reservoir is discharged through the water lowering valve 2a, (2). The water lowering valve lever 5 is designed to be slowly restored to its original state even after a user's hands are released after being operated once so that water in the water storage tank 10 can be sufficiently supplied to the toilet 2 during closing.

On the other hand, as shown in FIG. 2, the water-drop valve is a solenoid valve 5 ', and the button-type switch 6 for operating the solenoid valve 5' has only a solenoid valve 5 ' Respectively.
That is, when the user presses the switch 6, the solenoid valve 5 'is opened for a predetermined time, and during the open time, the control unit operates the main pump 40 so that water is supplied to the toilet. Here, when signals are simultaneously applied to the plurality of toilet seats 2, the main controller may sequentially open the solenoid valves 5 'of the respective toilet seats 2 to prevent water shortage.

The control unit 50 activates the main pump 40 to supply the water stored in the water storage tank 10 to the corresponding toilet bowl 2 when the water drop sensing unit senses the operation of the water drop valve and applies a signal. The control unit controls the operation of the main pump and the input / output device, and the main components are incorporated in the control box 50. The control box 50 is seated in a control box seating portion provided on the side wall of the water storage tank 10. The control panel of the control box 50 is exposed to the outside of the water storage tank 10 for easy adjustment and can be protected by the cover. The control unit activates the main pump 40 to supply the water stored in the water storage tank 10 to the toilet bowl 2 when the water drop sensing unit senses the operation of the water drop valve and applies a signal.

This will be described below with reference to FIG. According to another embodiment of the present invention, two or more main pumps 40, 40 'can be installed so that they can be operated individually. The plurality of main pumps 40, 40 'operate independently by the signal of the control unit. When a water descending signal is applied to several of the pots at the same time, there may be a water pressure drop phenomenon. By increasing the operation amount of the main pumps 40 and 40 ', it is possible to compensate the insufficient flow rate.

In some cases, as shown in FIG. 3, a plurality of water supply pipes 4 and 4 'and main pumps 40 and 40' may be provided in parallel, and the toilet 2 may be shared by several.

On the other hand, the water contained in the water supply pipe 4 is returned to the water storage tank 10 by its own weight, so that a cavity can be formed inside the water supply pipe 4. Then, after the water drop valve 5 is opened and the main pump 40 is operated, a certain amount of time will elapse before the water will be supplied to the toilet. This time delay is undesirable. Therefore, it is preferable to provide the check valve 41 at the initial portion of the water supply pipe 4. It is preferable that water pressure is maintained to some extent inside the water supply pipe 4 so that water is immediately supplied to the toilet 2 immediately when the water drop valve 5 is opened.

According to the embodiment of the present invention, the water supplementing portion for supplying water from the water source when the amount of the stored water in the water storage tank 10 is equal to or lower than the set value is further included. This is for the case where there is no water in the water storage tank 10 because the use of the common washstand 1 is small. The water replenishment section includes a water level sensing section for sensing the water level of the water in the water storage tank 10, a water pipe 6 having an end extending to the water storage tank 10, And a constant valve (7) for opening and closing the water pipe (6) by a signal from the control unit to supply a constant water into the water storage tank (10).

The water level sensing unit 60 may include three sensor electrode rods 61, 62, and 63, each having a different length, as a general method of measuring the water level, as shown in FIG. When the water reaches the end portions of the sensor electrode rods 61, 62 and 63, the sensor main body 64 recognizes this by energization and sends a signal to the control unit.

Hereinafter, the operation will be described with reference to FIG.

When a signal is detected at the low-point sensor electrode rod 61, it means that the water to be supplied to the toilet is insufficient. At this time, the control unit opens the water valve 7 to supply the constant. When a signal is detected at the high-point sensor electrode rod 63, it means that the water storage tank 10 is full. At this time, the control unit closes the water supply valve 7 to block the supply of the water.

When the period of the signal detected by the low-point sensor electrode rod 61 and the high-point sensor electrode rod 63 is abnormally short or long, the midpoint sensor electrode rod 62 serves as a bridge, The signal (own signal) of the electrode rod 62 is skipped, and the like, and sends an abnormal signal to the manager.

The water in the water storage tank 10 overflows to the sewage pipe 8 through the discharge port 16. [0050]
