Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply macerator toilet unit.

[0002]

2. Description of the Related Art A conventional toilet unit has accumulated water which is always kept at a constant water level inside thereof, and wastes such as defecation and toilet paper during defecation are accumulated in the accumulated water in a solid state. The structure is such that it is crushed halfway by running water after defecation and discharged to the outside.

However, in a general toilet unit, it is necessary to flush a large amount of water at a time to make an impact, so that the drainage process cannot be performed, and the diameter of the drainage pipe needs to be increased. There were major drawbacks to the simplification of piping work. In particular, saving water resources has become a big issue, and in the past, 8 to 10 liters or more of water was used for defecation, but in recent years, water saving type toilet units of 6 liters or less have also appeared. The trend is expected to widen.

Further, in recent years, the construction drainage system has also been improved, and the drainage pipes from the water supply equipment are laid on the floor slab without gathering, and this has a certain drop with respect to the vertical pipe. A system has been proposed in which drainage is performed by using a siphon force coming from this head, which is connected to a merging joint arranged at a position. The characteristic of this system is that the energy such as electric power is basically zero for drainage, and furthermore, the drainage pipes from the water supply equipment are all made of flexible resin pipes of the same diameter, so It provides ease of use and cost reduction as well as ease of maintenance.

An example of the diameter of such a resin pipe is 20
Where about mm is preferred, drainage from the flush toilet unit as a water supply equipment is no exception,
The diameters of the resin pipes used must also be unified.
Therefore, if necessary, the solid matter after defecation must be treated so as to easily pass through the resin pipe of this diameter. For this reason, it is necessary to make the structure of the toilet unit that can fluidize solids more quickly, and at that time, it is necessary to save the power consumption.

[0006]

SUMMARY OF THE INVENTION The present invention provides a toilet unit structure adapted to such a novel building drainage system.

[0007]

The structure of the present invention comprises a toilet unit main body, a stagnant water receiver connected to the rest unit main body, and a crushing unit for crushing solid waste etc. in the stagnant water receiver. It consists of a driving force receiving part with a built-in rotating shaft that supports the crushing part, and water is made to flow into the driving force receiving part at a high speed to rotate the rotating shaft. Is crushed and made into a fluid state, and then the water in the stagnant water receiving section is drained by the siphon force of the drain pipe connected to this.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION As an example of an embodiment of the present invention, a driving force receiving portion is provided with a supply port for supplying water to a stagnant water receiving portion and an outlet for discharging waste water obtained by crushing solid matter. Is provided with an inflow port for inflowing water accelerated by a water supply turbine and an outflow port for discharging this water.
Preferably, the toilet unit has a flow path that connects the supply port of the accumulated water receiver and the outlet of the driving force receiver.
In addition, the crushing section in the driving force receiving section has a blade for rotation,
The crushing section in the accumulated water receiving section is provided with a blade section for pressure feeding and crushing.

The generation of the siphon force that promotes drainage is caused by, for example, a joint for joining the drainage from the toilet unit to the drainage stack with a step with the drainage pipe, and connecting the drainage pipe to the joint and by the siphoning force corresponding to the step. Therefore, it is preferable to drain the water containing the waste in the accumulated water receiver.

As described above, the present inventors have already proposed a technique mainly for a high-rise building drainage system in which the fluid flow in the drainage pipe is a full-flow pressure / siphon flow. That is, it is a drainage system consisting of a vertical pipe that penetrates each floor, a drainage pipe that is guided from the water-related equipment on each floor, and a joint that connects this directly to the vertical pipe, and the level of the joint is lower than the level of the drainage floor slab. A system in which the vertical velocity component is sufficiently added to the fluid in the drain pipe before it joins the fluid in the vertical pipe, and the diameter of the drain pipe is reduced, and because it is a non-gradient pipe, its workability is easy and the space under the floor is effective. It has become possible to use it. Then, the present invention is adapted to be further applicable to the drainage of the toilet unit, and crushes solid matter and the like at the time of defecation into a fluid state,
This is intended to be discharged using the siphon force in the drainage pipe.

To further describe this drainage system,
All the drainage from the water supply equipment is individually and directly connected to a special joint that is installed in the stand pipe. In principle, the drain pipe is integrated to a diameter of 20 mm, and the connection level to the stand pipe is equivalent to the first floor height. (Used floor slab, 2 m) The standard is below.
Speaking of the drainage pipe, basically, since each independent flexible pipe is used, it does not have to be so large in capacity, a polybutene pipe with a diameter of 20 mm is sufficient, and the connection to each device is Since one type of pipe is sufficient, the merit in work is significantly large. Especially for the polybutene tube, the one-touch connection method has been developed, and it is optimal to use this for connection. In principle, drain pipes (flexible pipes) from each device are placed on the floor slab without being connected in the middle, and are connected to the joint at a level lower than each floor. Thus, flexible tubing is initially bent horizontally and then vertically. For this reason, the fluid in the flexible pipe is sucked in a state of high speed full flow by the siphon force generated by the step (drop) between the floor slab and the joint pipe, and joins with the fluid in the stand pipe.

[0012] Particularly, referring to the toilet unit, when pulverizing solids, electric power and a large amount of water are used, which increases the cost and hardly takes measures against power failure. The current situation. However, as described above, the present invention basically does not use electric power, but uses the siphon force due to the full flow in the drain pipe to discharge the solid matter in the toilet unit. It was possible to provide a toilet unit. As a concrete design level, water supply directly connected to the water supply 3 to 5 liters / washing (water supply pressure 1 to 2 kgf / cm
² ), Polybutene pipe with a diameter of 20 mm is adopted for the drainage pipe, and it crawls on the floor slab with no gradient, and the position of the joint between the floor slab and the vertical pipe (siphon height) is 2 m or less. Is.
