[Detailed description of the invention] The present invention relates to a cleaning device for a warm-water toilet, and its purpose is to provide a cleaning device that lowers the water pressure by a predetermined value to enable softer bidet cleaning than when cleaning defecation. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The hot water flush toilet cleaning device of the present invention (hereinafter referred to as the cleaning device of the present invention) will be described below with reference to embodiments shown in the drawings.

1 to 4 show an embodiment of the cleaning device of the present invention. The cleaning device 2 is installed in a warm water flushing toilet 1 and has a cylinder unit 20. The cylinder unit 20 has an initial position A, a toilet cleaning position B, and a bidet cleaning position C. As shown in FIG. 3, the cylinder unit 20 includes a cylinder 21.
and two-stage plungers 22 and 23 which are attached to the cylinder 21 so as to be expandable and retractable (contracted by extension springs 31 and 32 due to water pressure). A nozzle 24 is provided at the tip of the plunger 23, and the nozzle 24 is connected to the water channel 2 in the plungers 22, 23.
Connects with 8. On the other hand, an annular auxiliary chamber 30 is formed at the base of the cylinder 21 by the plunger 22 when the plunger 22 is contracted. Next, as is clear from FIG. 2, the waterway 28 of the cylinder unit 20 is connected to the tank 17 via the main waterway 26.
connected to. Further, the auxiliary chamber 30 is similarly connected to the tank 17 via the auxiliary waterway 27. In addition, a manual or electromagnetic valve 19 is provided in the main waterway 26, and a manual or electromagnetic valve 19 is provided in the auxiliary waterway 26.
7 are each equipped with a solenoid valve 29. The tank 17 is equipped with a heater 18 that operates in conjunction with the opening and closing of a valve 19, and the heater 18 heats water sent from a water supply source 3 such as a city water pipe through a pressure reducing valve 4 to make it hot water. . Next is the pressure reducing valve 4, which has a magnetic coil chamber 7 and a water chamber 8 partitioned off by a diaphragm 6 within the main body 5. A magnetic body 15 fixed to the main body 5 is placed in the magnetic coil chamber 7.
and a magnetic coil 14 that is magnetized and attracted to the magnetic body 15 when energized are housed. On the other hand, in water chamber 8,
An orifice 10 whose flow path area is made variable by a valve body 9 is provided. The orifice 10 is a water supply source 3
An inflow chamber 8a connected to the tank 17 and an outflow chamber 8b connected to the tank 17 are communicated with each other. Further, the valve body 9 is connected to a magnetic coil 14, and an adjustment knob 12 is connected to the valve body 9.
In the embodiment in which the tension spring 11 is expanded and contracted, it can be pressed by the force of the tension spring 11. The magnetic coil 14 is then connected in parallel to the solenoid valve 29, and the parallel circuit is connected to the power supply via the switch 16.

The operation of the cleaning device of the present invention shown in the above embodiments will be explained below for each of defecation cleaning and bidet cleaning.

First, for cleaning when defecating, the user opens the valve 19 manually or by pressing a cleaning switch (not shown) if the valve 19 is an electromagnetic type. On the other hand, since the heater 18 is linked to the valve 19, the valve 19
When the heater 18 is opened, the heater 18 is energized.
This allows water to flow from the water supply source 3 to the tank 1 via the pressure reducing valve 4.
The water supplied to the cylinder unit 7 is heated by the heater 18 in the tank 17 to become hot water, and then passes through the valve 19 and the main waterway 26 to the waterway 28 of the cylinder unit 20.
flows into. As a result, the plunger 23 is
As shown in FIG. 3, the nozzle 24 extends against the spring 32, and hot water is jetted out from the nozzle 24 to cleanse the user's local area. To adjust the strength of the fountain, the user turns the adjustment knob 12 to release the spring 11.
expand and contract and adjust its force. As a result, as the degree of decrease in the water pressure in the orifice 10 changes, the water pressure in the outflow chamber 8b changes, and as a result, the intensity of the fountain from the nozzle 24 changes.
When the cleaning is completed, the user closes the valve 19, which lowers the water pressure in the water channel 28, causing the plunger 2 to close.
3 will be compressed by the force of the spring 32.

Next is bidet cleaning, in which case the user must use valve 1.
In addition to opening switch 9, switch 16 is closed. As a result, the solenoid valve 29 is opened, and the tank 17 is communicated with the auxiliary chamber 30 of the cylinder unit 20 via the auxiliary waterway 27. Therefore, the water pressure in the auxiliary chamber 30 increases, and the plunger 22 extends against the spring 31, as shown in FIG. On the other hand, since the plunger 23 also extends in the same way as in the case of urinating, both the plungers 22 and 23 end up extending. On the other hand, when the switch 16 is closed, the magnetic coil 14 is energized and excited, and is attracted to the magnetic body 15. As a result, the valve body 9 receives a magnetic force that opposes the force of the spring 11, and as a result, the degree of decrease in water pressure in the orifice 10 increases. Therefore, the water pressure in the outflow chamber 8b is reduced, and the intensity of the fountain from the nozzle 24 is automatically reduced by a predetermined value corresponding to the magnetic force compared to the case of urinating. Upon completion of cleaning,
The user closes the valve 19 and opens the switch 16, which causes the water pressure in the water channel 28 to drop, causing the plungers 22 and 23 to contract under the force of the springs 31 and 32, respectively.

5 and 6 show other embodiments of the present invention,
In this case, the pressure reducing valve 4 is the main waterway 2 downstream of the tank 17.
6, and the solenoid valve 29 is closed several seconds after being energized, so that the bidet cleaning water does not pass through anything other than the pressure reducing valve 4. In addition, not only the electromagnetic valve 19 but also the magnetic coil 14 are energized by the washing switch 33 operated when washing the stool, and the current value can be varied by the washing volume 34. The water force can be electrically adjusted during stool washing without using the adjustment knob 12 in the previous embodiment. Furthermore, the switch 16 for the bidet includes a valve 19 and a solenoid valve 2.
9 and the magnetic coil 14. The value of current flowing through the magnetic coil 14 when the bidet switch 16 is closed is the value of the current flowing through the cleaning volume 3.
4 is made variable by a bidet volume 35 provided separately and in parallel. The energization of the solenoid valve 29 is time-controlled by a timer 36 that closes the contacts for only a few seconds from the start of energization.
The circuit diagram of FIG. 6 shows the above as an electric circuit, and the cleaning switch 33 is shown as a two-way type, and the bidet switch 16 is shown as a three-way type.

To explain the operation of this embodiment, when the cleaning switch 33 is closed when cleaning the toilet, the valve 19 opens and hot water flows into the main water channel 26 and is ejected from the nozzle 24. At this time, the magnetic coil 14 is also The current set by the volume 34 flows, and this volume 34
The opening degree of the valve body 9 can be adjusted with . For bidet cleaning,
It is only necessary to close the bidet switch 16, and the operation can be performed independently of the stool washing operation. That is, when the valve 19 and the solenoid valve 29 are opened, both the plungers 22 and 23 are extended, and even if the solenoid valve 29 is closed after the timer 36 is activated, the plunger 22 is also extended by the water pressure from the main water channel 26 as shown in FIG. water fountain in the bidet position. At this time, the magnetic coil 14 is also energized, but since the bidet volume 35 is provided independently of the cleaning volume 34, it is necessary to set the current value in advance to a value different from the current setting value for defecating. , the fountain automatically adjusts to the optimum strength for a bidet (low water pressure and soft). In addition, in both cases of fecal washing and bidet washing, by adjusting the respective volumetric volume 34, 35 during use, the fountain power can be changed according to each person's preference.

The cleaning device of the present invention may have the following configuration in addition to those shown in the above two embodiments. That is, auxiliary waterway 2
The solenoid valve 29 at 7 is a drive circuit for the cylinder unit 20 during bidet cleaning. Therefore, if the configuration of the cylinder unit 20 changes (for example, if the plunger is not a two-stage type), the drive circuit should be changed to correspond to the change. good.

The hot water flush toilet cleaning device of the present invention is constructed as described above, and provides the following excellent effects.

(1) The cleaning device of the present invention particularly includes plungers 22 and 23 for bidet cleaning, which are connected to a power source in parallel with a circuit that flows a current value for bidet cleaning through the magnetic coil 14 via a common switch 16. Since it has a drive circuit, switch 16 is activated when cleaning the bidet.
With this operation, the plungers 22 and 23 are extended to the bidet cleaning position, and the magnetic coil 14 of the pressure reducing valve 4 is energized with a preset current value for the bidet, so that the strength of the fountain is adjusted to the level required for fecal cleaning. It automatically changes to the optimal strength for different bidets, making it extremely easy to use.

(2) The cleaning device of the present invention particularly has a pressure reducing valve 4 that excites the magnetic coil 14 and adjusts the degree of decrease in water pressure by its magnetic force, so the degree of decrease in water pressure can be adjusted by adjusting the magnetic force. This can be done extremely easily.
