Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a device that discharges cleansing water toward private parts of the human body, and in particular, the device is always held in its stored position by the bias of a spring or the like, and when in use, the cleansing water is released. The cleaning nozzle is of a type that extends to a predetermined position against the force of water.

[Prior art and its issues]

Generally, this type of device has an added function to adjust the force of the washing water according to the user's preference in order to wash sensitive private parts of the human body. However, since the cleaning nozzle is extended by the water force, if the water force is set weakly, it takes a long time to extend to a predetermined position and start cleaning.

Therefore, the problem with this invention is whether it is possible to extend the cleaning nozzle to a predetermined position within a certain short period of time, regardless of the strength of the water force set in the adjustment means.

[Means to solve the problem]

This device applies a water force of a predetermined pressure higher than the lower limit water force that can be adjusted by the adjusting means to the washing nozzle for a certain period of time at the start of washing, and then releases washing water at the water force set by the adjusting means. The above-mentioned problem is solved by providing a control means to cause the above problem to occur.

In the following embodiments, the adjustment means corresponds to the adjustment panel 17, and the control means corresponds to the microcomputer 20.

〔Example〕

Examples thereof will be described below based on the drawings.

FIG. 1 is an explanatory diagram showing the structure of an embodiment of the present invention, in which 1 is a toilet bowl, 2 is a toilet seat, 3 is a low tank for flushing, and 4 is a washing device main body. A pump 5 sucks water from the low tank 3 through a filter 6 and a hose 7. A hot water tank 8 communicates with the pump 5 via a hose 9 and is equipped with an internal heater to heat the stored water to a constant temperature. A cleaning nozzle 10 communicates with the hot water tank 8 via a hose 11 and a solenoid valve 12, and discharges cleaning water that is sucked from the low tank 3 and heated in the hot water tank 8 as the pump 5 is driven. Note that this cleaning nozzle 10 is
A plunger 15 having a water discharge port 14 formed at its tip is provided inside the outer casing 13. Normally, the plunger 15 is held in the storage position shown in the figure by the bias of a spring, and when in use, the plunger 15 is inserted into the casing 13 as the pump 5 is driven. The plunger 15 is configured to extend outward due to the force of the guided cleaning water and bring the water outlet 14 to a predetermined cleaning position.

Reference numeral 16 denotes an operating section, which is equipped with a cleaning switch 18. Reference numeral 17 denotes an adjustment panel that allows adjustment and setting of the water force and temperature of the flushing water.

FIG. 2 is a diagram showing a control circuit for the pump 5. As shown in FIG. A microcomputer 20 outputs a control signal according to a program written in a built-in ROM, and here mainly controls the water pressure of the cleaning water set in the control panel 17 through an A/D converter 21. The phase control timing t of the pump 5 is calculated according to the read water force, and the energization of the pump 5 is controlled via the output circuit 22.

In the microcomputer 20, the zero cross of the power supply is connected via the input/output circuit 22 (see Figure 3 A).
The input/output circuit 22 detects the timing of the thyristor element 23 of the pump control circuit by delaying the phase control timing t from this zero-crossing time.
Give a trigger pulse to the gate. The voltage applied to the pump 5 and the trigger pulse signal thus obtained are shown in FIGS. 3a and 3b. In addition, when starting cleaning,
That is, when the pump 5 is driven, the adjustment panel 17
Phase control timing t determined according to the setting of
A predetermined program operation is carried out regardless of this, and this point will be described below.

FIG. 4 is a flowchart showing the operation of the embodiment, and the operation of the embodiment will be explained below based on this diagram.

When the cleaning switch 18 is turned on at the operation unit 16, 1, a predetermined phase control timing _t2 is loaded, and 2,
3. The pump 5 is operated at this timing _t2 . When the timer time T ₂ has elapsed, 4, a predetermined phase control timing t ₁ is loaded 5, and the pump 5 is operated at this timing t ₁ 6. When the timer time _T1 has elapsed, the phase control timing t determined according to the setting of the adjustment panel 17 is loaded at step 7, and the pump 5 is operated at step 8, continuing until the cleaning switch 18 is turned off.

FIG. 5 is a time chart showing changes in the force of the washing water accompanying the above operation. The cleaning switch
During the timer time _T2 after being turned on, the nozzle extension pressure is lower than or equal to the nozzle extension pressure (that is, the pressure is low enough not to extend the nozzle 10) based on the phase control timing _t2 .
During this operation, the cold water remaining in the cleaning channel including the cleaning nozzle 10 is discharged. During the timer time T ₁ after T ₂ has elapsed, the washing nozzle 10 is operated at a high pressure exceeding the nozzle extension pressure that can quickly extend the cleaning nozzle 10 based on the phase control timing t ₁ . Thereafter, the water pressure of each desired force is applied according to the phase control timing t determined based on the settings on the adjustment panel 17.

Therefore, in the above embodiment, first, the system is operated at low pressure for a certain period of time to discharge the cold water in the pipe, and then is operated at high pressure for a certain period of time to make the cleaning nozzle 10 protrude toward a specified position, and then the desired water force is set. It sprays water,
The hot water heated in the hot water tank 8 can be discharged as the nozzle 10 quickly expands.

[Effect of idea]

This device is constructed as described above, and even if the water force setting in the adjustment means is weak, the cleaning nozzle is always extended by the water force of a predetermined pressure regardless of this setting, so it takes a particularly long time to start cleaning. There is no such inconvenience, and cleaning can always be started in a constant short time.
