Description of the Related Art Sanitary appliances such as a flush toilet, a washbasin, and a sink (a deep sink for washing a rag or a mop) have a structure in which a drain pipe is extended from an outlet to discharge sewage. However, in order to prevent the odor of the drain pipe from flowing backward through the sanitary equipment, that is, to prevent the odor from leaking into the room, a water sealing portion called a trap is provided near the outlet of the sanitary equipment. The trap locally fills water by bending a drain passage into a horizontal S-shape or the like, and seals air contaminated with the water.

て封水機能が失われることを「封水切れ」という。[0003] By the way, as a drain pipe, a piping structure combining a horizontal pipe and a vertical pipe (specifically, a piping structure in which the tip of a horizontal pipe is connected to a vertical pipe) is widely adopted. Water trapped in the trap may be sucked out. In addition, since the drainpipe generally passes under the floor and inside the frame wall, a Ω-shaped rising portion may be formed on the way. The rising portion serves as a siphon to suck out the water stored in the trap, lowering the water level and lowering the water sealing function. The state in which the water stored in the trap is sucked out and the water level drops so much that the water sealing function is lost is called "water out of water".

When one of the flush toilets is washed with water, the water in the other flush toilet may be cut off due to the effect. As described above, when the outlet side of the siphon becomes a negative pressure or a vacuum, water is physically sucked and discharged, and the sealing may be broken.

(The reference numeral is a diversion from that described in the official gazette. The same applies to the following.) Shows a structure in which an instrument trap 22, a pressure feeding and draining unit 3, a flexible drain pipe 4 and a ventilation pipe 6 are provided. Since the ventilation pipe 6 has an air opening 150 mm above the overflow surface of the sink 21, there is no fear that sewage will overflow from this air opening. If the drain pipe 4 fluctuates in pressure, the ventilation pipe 6 Absorbs pressure fluctuations. That is, the effect of the ventilation pipe 6 can effectively prevent the occurrence of water breakage in the instrument trap 22.

The opening of the atmosphere also serves as a discharge port of the odor in the exhaust pipe 4.
For this purpose, the air opening of the ventilation pipe 6 needs to be exposed to the outside. As a result, the ventilation pipe 6 becomes long, and a space for passing the long ventilation pipe 6 must be secured in the building frame, which increases with material costs and construction costs, increases the cost of drainage pipe construction, and increases the construction period. Has become a factor of lengthening. Therefore, an object of the present invention is to provide a technique capable of preventing water from being cut off without providing a ventilation pipe.

3. Tongue 14, inverted U-shaped passage 15, forced pumping device 65
And a flexible drainage pipe 66 having a relatively small diameter.
The water supply valve 22 is automatically opened to supply water to the ball 13 through the orifices 23... Opened in the rim 12, and the water is stored at the bottom of the ball 13.
By lowering the lower end of the trap, the trap 25 is formed, and the trap 25 can seal the odor of the drain pipe 66 flowing backward through the forced-pressure feeding device 65.

を発揮するものであれば、種類、形式は任意である。The forcible pressure feeding device 65 has three functions of suction, crushing, and discharging. For example, a pump having a cutter function is preferable. The pump can rotate the rotating blades at high speed to make the pump inlet vacuum and the pump outlet high pressure, and exhibit a cutting action if the blades are in a cutter shape. Note that a gear pump or a roots pump cannot be used to make the rotating portion into a cutter shape, but can be used because dirt can be crushed by engagement of the rotating portion (gear or the like). Accordingly, the type and the type of the forced-pressure feeding device 65 are arbitrary as long as they exert three effects of suction, crushing, and discharging.

However, when the forcible pressure feeding device 65 is stopped, sewage remains in the small-diameter flexible drainage pipe 66. Therefore, it would be better if cleaning could be performed with clean water.

を洗浄することができる。FIG. 6 shows an operation waveform diagram of the pump and the water supply valve, wherein the upper part shows a pump as a forced pumping device, the middle part shows the state of the water supply valve, and the lower part shows the prediction of the occurrence of a siphon in the drain pipe.
The horizontal axis is the time axis. The pump is started by the flushing start command or flushing start signal issued when the service is completed at the point, the operation is continued for t1 hours, the water supply valve is opened, and the water is supplied only for the time t2 (t2 <t1). . Then, the sealed water 41 shown in FIG. 5 enters the forced-pressure feeding device 65 through the inverted U-shaped passage 15 together with the waste, and flows out through the drain pipe 66. At the time t1, a siphon is generated in the toilet and the waste can be effectively discharged. At time t2, the ball can be washed.

As described above, a siphon may be generated in the drain pipe because the drain pipe includes a vertical pipe. This is indicated by imaginary lines in the lower part of the figure, but can be expected to occur at almost points. A siphon may not be generated, but if a drainage test is performed on the completed drainage pipe, it is generally possible to specify the time of occurrence and its length.

Even if water is supplied when a siphon is generated in the drain pipe, the water is only rapidly discharged. Therefore, after a lapse of time t4 from the time when the siphon is predicted to be ended, the water supply valve is opened, and a time t5 is set in the toilet trap. Water only. This will restore the seal. The time t2 and the time t5 can be set arbitrarily and need not always be the same. Therefore, the time t2 is set to a certain time,
The time t5 is called a predetermined time and is distinguished.

止切れを防止することができる。FIG. 7 is a view showing another embodiment of FIG. 6. The horizontal axis is a time axis. The pump starts to rotate at a point according to the operation command of the control unit, and the operation is continued only for a time t7. Thereafter, the pump is stopped. Suppose you did. At this time, the water supply valve supplies water in conjunction with the operation of the pump. However, in other time zones, the water supply valve is opened at every time t8, the water supply state is established, and the water supply valve is closed when the time t9 has elapsed from the start of water supply. Such control is performed by the control unit 61 shown in FIG.
Let me do it. Even when the forced-pressure feeding device 65 is stopped, it is possible to prevent the seal from being broken.
