BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a flush toilet seat apparatus according to the present invention. FIG. The same elements as those in FIG. 6 are denoted by the same reference numerals. As shown in FIG. 1, the cleaning toilet seat device of this embodiment has a low tank 1 at the rear and a toilet 2 at the front. The water supply source is
For example, a water pipe, to which a water supply pipe 4 is connected. A branch water stopcock 5 is connected to the end of the water supply pipe 4, and one of the external water pipes 6 branched from the branch water stopcock 5 supplies the washing water to the low tank 1, and the other external water pipe 7.
Supplies cleaning water to a cleaning water tank 31 in the housing 3.

As shown in FIG. 2, the housing 3 has a horizontal portion 3C extending on both sides of the toilet bowl on the rear portion of the toilet bowl 2, and two sleeve portions 3A hanging from both ends of the horizontal portion 3C to the floor. 3B. As shown in FIG. 5, the washing water tank 15 is a container which is stored in an L-shape over a part of the left sleeve 3A and a part of the horizontal portion 3C, and is stored in the sleeve 3A as shown in FIG. An internal water pipe assembly 16, which is a feature of the present embodiment, is connected to the portion to be connected.

The inner water pipe assembly 16 includes a cylindrical member 17 serving as a water supply port connected to the outer water pipe 7 and the nut 10, a filter 18a formed of a cylindrical wire mesh, and mounting screws 18b for fixing the filter 18a. And a valve unit including an opening / closing solenoid valve 19 for intermittently connecting the washing water passing through the filter 18a and a diaphragm valve 20 (FIG. 4) for adjusting the water pressure of the washing water. The casing 21 includes a cylindrical member 17 and a filter 18.
a, water passages 16a to 16d for connecting the opening / closing solenoid valve 19, the diaphragm valve 20, and the washing water tank 15 in series are formed.

In the internal water pipe assembly 16, a part of the tubular member 17 and the mounting screw 18b of the strainer unit 18 are projected from a pipe opening 22 formed in the front side 3T of the sleeve 3A. . Here, the axial directions of the cylindrical member 17 and the strainer unit 18 obliquely intersect with each other, and the narrow side faces the front side 3T. The advantage of this is that the length of the pipe opening 22 in the longitudinal direction can be shortened, and as described later, the appearance of the toilet bowl from the front is tidy. In addition, the front side 3T of the sleeve 3A is inclined downward with respect to the floor surface, so that it does not face from the front of the toilet bowl as well as sitting on the toilet seat 13.

The opening / closing solenoid valve 19 once guides the washing water from the water passage 16b to the small chamber 19a and transfers the washing water from the small chamber 19a to the diaphragm valve 20 from an umbrella-shaped valve element 19c integral with the valve hole 19b. A plunger 19e serving as a valve for opening and closing the valve hole 19b is led out to the water passage 16c, and is connected to the solenoid 1
Opening / closing control is performed in synchronization with the cleaning operation by the force relationship between 9d and the pressing spring 19f. Further, the diaphragm valve 20 is a movable valve 2 integrated with the diaphragm 20a.
At 0b, the valve hole 20c between the water passage 16c to which the tap water pressure is transmitted and the water passage 16d to which the washing water tank pressure is transmitted is opened and closed. With the valve hole 20c open, the pressure in the water passage 16d attaches the diaphragm 20a. When the force of the spring 20d is exceeded, the valve hole 20c is closed.

The housing 3 includes a washing water tank 1.
A nozzle mechanism (not shown) provided with either or both of an anal cleaning nozzle and a bidet cleaning nozzle for providing the cleaning water temporarily stored in 5 for local cleaning. The nozzle mechanism is composed of a group of operation buttons 2 arranged on the upper surface of the sleeve 3A.
3 is operable. The washing toilet seat device of the present embodiment also sends the washing water from the water supply pipe 4 to the low tank 1, and also sends it to the internal water pipe assembly 16 through the external water pipe 7, and is integrally formed with the internal water pipe assembly 16. The open / close electromagnetic valve 19, the diaphragm valve 20, the strainer unit 18 and the like can supply the washing water to the washing water tank 15 according to the nozzle operation, adjust the water pressure, and remove solids in the washing water.

The features of the present flush toilet seat on piping are as follows.
The strainer unit 18 externally piped outside the housing is replaced with the internal water pipe assembly 16 integral with the valve unit.
In the housing 3. For this reason, the structure of the external piping is extremely simple because the external water pipe 7 extends only from the housing 3, and the valve unit and the strainer unit 18 can be easily incorporated into the housing 3.

With such a simple piping configuration, the present flush toilet seat device has two synergistic effects.
First, even if a connection portion is provided on the front side portion 3T of the sleeve portion 3A or the mounting screw 18b of the strainer unit 18 is protruded, there is no particular problem in appearance.
In addition, the connection point of the external water pipe 7 and the strainer unit 18
Since the mounting screw 18b is located on the front side 3T of the sleeve 3A, even when the toilet side area is narrow, the operator does not take an unnatural posture during installation of the device, and the external water pipe 7 Can be easily carried out to the housing 3.

That is, in this embodiment, the front side 3T of the sleeve 3A is obliquely downward with respect to the floor surface, and the external water pipe 7 extends from the front side 3T at the piping location and the mounting screw 18b. Does not enter the front with respect to the view from the front of the toilet. Also, if the shape of the sleeve 3A is a perfect square box shape, even if the pipe location of the external water pipe 7 and the mounting screw 18b are protruded to the vertical front side, the external appearance can be improved. Above, there is no particular feeling of complexity. In this case, if the connection point of the external water pipe 7 and the mounting screw 18b are made to protrude from the bottom, the external water pipe 7
Is completely removed from the field of view from the front of the toilet.

The cylindrical member 17 of the internal water pipe assembly 16 and the mounting screw 18b of the strainer unit 18
May project from a separate piping opening, but in this embodiment, the axial directions of the cylindrical member 17 and the strainer unit 18 of the internal water pipe assembly 16 obliquely intersect, and the narrow angle side is the front side portion. Since the tube member 17 and the strainer unit 18 are opposed to the 3T, the cylindrical member 17 and the strainer unit 18 can protrude together from the piping opening 22 formed in the front side portion 3T, and the appearance is tidy.

On the other hand, the cylindrical member 1 to which the external water pipe 7 is connected
7 and the mounting screw 18b are provided with a piping opening 22 in the front side 3T of the sleeve 3A hanging down to the floor in the toilet side area, and protrude forward of the toilet.
Without bending your body to cover it or leaning one shoulder, it is located in front of the toilet bowl,
The external water pipe 7 extending below the front side of the sleeve 3A is connected to the cylindrical member 17 by the connecting nut 10, and the filter can be cleaned by easily checking the position of the mounting screw 18b when cleaning the strainer. it can.

As described above, the present invention contemplates a pipe which can be worked from the front of the toilet and does not impair the appearance. Although the above embodiment is applied to a system that requires water pressure adjustment, as another embodiment, for example, a pump for pumping washing water is provided in the low tank 1, and the water pressure adjustment is performed by the constant capacity of the pump. It is also possible to apply the present invention to a system that does not require it. Also in this case, the tubular member 17 and the mounting screw 18b protrude from the piping opening 22 of the front side 3T similar to the embodiment, and the piping work and the strainer cleaning work are easy, and the appearance is not spoiled.
