Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a toilet flushing method and device.

[Conventional technology]

Conventionally, this type of device flushes a small volume of pre-treated water or small flush water for sound-muffling flushing or urinary flushing, or flushes fecal flushing water based on the amount of time that has elapsed since the user entered the toilet. There is a known system in which a large volume of large-scale wash water is selectively flowed through.

[Problem to be solved by the invention]

However, with the above-mentioned device, when switching between pre-treatment and main washing, or changing the volume of washing water depending on the amount of urine and urine, the amount of water is only increased or decreased, and the force of the water discharged may be changed. There wasn't. Therefore, even though it is necessary to run a small amount of water over a long period of time for silent cleaning,
Water is sprayed vigorously, and when the water spraying ends, noise-reducing cleaning is repeated and the water-saving effect cannot be obtained, and in the case of main cleaning, even though it is necessary to flush water with force, There was a problem in that the water was allowed to flow for a long period of time, making complete cleaning impossible.

This invention was made to solve the above problems, and its purpose is to reliably adjust the amount and force of flushing water based on the predetermined toilet entry time and according to the purpose of water discharge. To provide a method and device for discharging water from a toilet, thereby making it possible to reliably achieve the intended purpose of discharging water and to save water.

[Means to solve the problem]

In order to achieve the above object, in this invention, when an operation for discharging water is performed within a predetermined first set time after entering the toilet, pre-treated water is flushed over a required period of time, and When an operation for discharging water is performed after the first set time has elapsed and before reaching the second set time, the small wash water is flowed for a time shorter than the required time.

Further, when an operation for discharging water is performed after the second set time has elapsed since entering the toilet, a larger volume of large flush water than the small flush water is flushed, or when the user leaves the toilet after entering the toilet. It is desirable that the large volume of washing water be flushed after leaving the room when the second set time has elapsed, and furthermore, water can be sprayed even after the second set time has elapsed and before leaving the room. This can be said to be effective from a cleaning standpoint.

Further, in order to perform the above operation, in the present invention, a valve is provided in a pipe line connected to the toilet bowl and a valve chamber communicating with the pipe line,
A main valve that can be opened and closed between the two, a pilot that connects the pipeline and the valve chamber on the upstream and downstream sides of the main valve, a pilot valve that can open and close the pilot on the downstream side, and a pilot valve that operates the pilot valve. an adjusting means capable of adjusting the amount of opening/closing operation of the main valve; a detecting means for detecting a person entering or leaving the toilet and outputting a detection signal; and an outputting a command signal for discharging water. The apparatus is provided with an operating means and a control means for measuring the entry time based on the detection signal and controlling the actuating means and the adjusting means in accordance with the entry time and the input of the command signal.

[Effect]

When a person entering the toilet is detected by the detection means, the control means starts measuring the entry time, and within the first set time,
When the operating means performs an operation for discharging water, the control means operates the viroft valve and the main valve by controlling the operating means and the adjusting means to pipe a predetermined volume of pretreated water over a required period of time. Flush from the street into the toilet bowl. Further, when the water spraying operation is performed before reaching the second set time, the control means causes the small wash water to flow for a time shorter than the required time. Furthermore, when a water discharge operation is performed after the second set time has elapsed, a larger volume of large wash water than the small wash water is caused to flow. In addition, after the second set time has elapsed,
After the detection means detects the exit of the person entering the room, the control means causes a large volume of large-volume washing water to flow. Furthermore, when the water spraying operation is performed after the second set time has elapsed, the same amount of water as the small wash water is caused to flow.

Further, a connecting shaft 10 is protruded from the main valve 6 and enters a guide hole 9a of the operating shaft 9, and as the stepping motor 7 rotates, the operating shaft 9 is rotated to change its arrangement position. By doing so, the distance X between the inner ring portion of the guide hole 9a and the tip of the linking shaft lO is adjusted.

On the upstream and downstream sides of the partition wall 3 in the pulp 1, a pair of pylons 11 are provided which communicate with the pipe line 2 and the valve chamber 5, respectively.
．． 12 are formed. On one side of the stepping motor, a solenoid 13 molded from a resin material is attached to the pulp 1.
A plunger 14 constituting a pilot valve capable of opening and closing the pilot 12 on the downstream side is mounted so as to be movable along its axis, and is biased by a spring 15 in the closing direction.

The interval X and the opening time of the pilot 12 are set depending on the type of cleaning. That is, pretreatment cleaning (x=
xl), 6 l/15 seconds.

For a small urine wash (x-x2), it is 6115 seconds.

Then, similarly to the above case, the pilot 12 on the downstream side is opened for the required time (5 seconds), and the valve chamber 5 becomes under negative pressure. At this time, the stamping motor 7 is moved so that the distance X becomes "X2".
is rotated, and the main valve 6 is opened in accordance with the interval X. Then, the urinary washing water No. 61 is flushed with strong force for 5 seconds to ensure reliable washing.

On the other hand, if the determination in S6 is NO and the entry time t exceeds the second set time T2, the microcomputer 21 determines in S9 whether or not the touch switch 25 is operated, and when the touch switch 25 is operated. , the microcomputer 21 energizes the solenoid 13 for the required time (10 seconds in the example). Then, as in the previous case, the downstream pilot 12 is opened for the required time (10 seconds),
The valve chamber 5 becomes under negative pressure. At this time, the stamping motor 7 is rotated so that the interval X becomes "X3", and the main valve 6 is opened in accordance with the interval X. Then, 12
41 main fecal washing water is flushed vigorously for 10 seconds to ensure reliable washing (SIO).

Then, when the user leaves the toilet and the input of the detection signal from the sensor 24 is stopped, the determination in S11 is YES.
Then, the microcomputer 21 clears the room entry time t (
Sll, 312).
