Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a sanitary cleaning device that is attached to a toilet bowl and mainly cleans the private parts of the human body after using the toilet.

[Prior art]

Conventionally, this type of sanitary washing device used an electromagnetic pump as a means of obtaining water discharge pressure for cleaning, and was configured to control the power supply to the pump via a phase control circuit to adjust the amount of water discharged. something is known.

[The problem that the idea attempts to solve]

By the way, if the amount of water discharged is reduced by phase control, the power supply time for each power supply cycle of the electromagnetic pump will be shortened, and the plunger of the electromagnetic pump will not be able to perform a full stroke operation, and its stroke will be kept small, so the pump used will be There is a problem in that machine differences such as spring errors and lubrication performance are amplified, and the water discharge performance varies greatly depending on the device, making it difficult to compensate for uniform performance.

In addition, in order to obtain a sufficient cleaning effect with this type of device, it is necessary to wash at a water pressure higher than a certain level, but if the water is washed continuously at a pressure higher than this required water pressure, some people, such as those with hemorrhoids, may Since some patients may complain of pain, there has been a desire to develop a device that can provide a high cleaning effect without causing pain.

Therefore, the challenge of this invention was to obtain stable control operations at all times and to achieve a high cleaning effect without causing pain to the user.
The point is how to do it.

[Means to solve the problem]

This invention consists of a water discharging means for washing private parts of the human body by obtaining water supply pressure from an electromagnetic pump, an adjusting means for arbitrarily setting the amount of water discharged from the water discharging means, and a power supply per cycle of a power supply waveform to the electromagnetic pump. The above problem is solved by providing a control means for maintaining the time at a predetermined value or more and for varying the period of the power supply waveform according to the settings in the adjustment means.

[Effect]

With this configuration, the power supply time per cycle to the electromagnetic pump is maintained at a predetermined time or more, and the pump always performs a stable stroke operation, while the power supply interval is varied to increase or decrease the amount of water discharged. This operation causes the water to pulsate as the amount of water is reduced, providing superior cleaning power compared to constant-pressure water spraying with the same amount of water.

In the figure, reference numeral 7 denotes an electromagnetic pump, which communicates with a water supply port 8 on the back of the main body 4, and introduces water therein from the low tank 3 through a hose 6 as cleaning water.

The operation of the control system of the present embodiment having the above configuration will be explained based on the flowchart shown in FIG.

(1) Waiting state until an operation input is made on the operation button 20.

(2) In step 1, the operation button 20 is turned on.
Then, the set amount in the water discharge amount adjusting means 27 is read via the A/D conversion circuit 29.

(3) Compare the read set amount with the previously read amount and if there is no change, proceed to step 7.
The set amount is updated and written to the internal register each time there is a change, but
It is cleared at the same time as OFF, so step 1
Immediately after the switch is turned on, the flow moves to step 3 unconditionally.

(4) When a change in the set amount is detected in step 2, the control means 29 calculates the energization interval t1 (OFF time of the pump 7) to the electromagnetic pump 7 according to the new set amount according to the built-in program. In other words, as shown in FIG. 5, the larger the set amount is, the more the power feeding interval t
It is programmed to shorten t1 and to lengthen t1 if there is less.

(5) Subsequently, the control means 29 calculates the power supply time t2 per cycle to the electromagnetic pump 7 according to the newly set amount according to the program. That is,
As shown in FIG. 6, the power supply time t2
is always maintained at a certain length or more, but the smaller the set water amount and water pressure and the longer the power feeding interval t1 calculated in step 4, the longer t2 is set approximately in proportion to this. (6) Step 4,
Based on the data of t1 and t2 calculated in step 5, the built-in timer of the control means 29 counts and outputs an ON/OFF signal for the pump 7 to the interface 30, and the interface 30 outputs an ON/OFF signal for the pump 7 to the electromagnetic pump 7 in response to this signal. power supply. The power supply waveform at this time is as shown in FIG.

(7) Detect whether or not the operation button 20 is turned off, and repeat the operations of steps 2 to 6 above until it is turned off.

(8) If OFF is detected in step 7, the power supply operation to the pump is stopped, the read data in the control means 29 is cleared, and the process returns.

As in the above embodiment, the power supply interval t to the pump 7 is adjusted according to the amount set in the adjustment means 27.
1 as 4th, within a certain range (in this example, from 10 msec to
7 pumps per unit time, increasing or decreasing by 100msec)
The amount of water discharged is adjusted by changing the number of plunger operations.

Furthermore, when the interval t1 is lengthened, the water pressure in the pipe decreases accordingly, and a large water resistance is encountered due to the plunger operation of the pump 7.
Since a larger amount of electricity is required to perform the same stroke operation, it is not possible to perform a full stroke operation with the same power supply time when the amount of water discharged is high, and therefore the machine difference as mentioned in the conventional example at the beginning is not possible. It will happen. Therefore, as shown in FIG. 5, the power supply time is extended within a certain range (6 msec to 10 msec in this example) in approximately proportion to the power supply interval to always provide stable full stroke operation.

[Effect of idea]

This invention is constructed as described above, and produces the following excellent effects.

Unlike phase control, which reduces the power supply time and throttles the flow rate, the power supply interval is varied, so the pump's plunger can perform a reliable stroke and eliminates differences between pumps such as lubrication performance and spring error. However, substantially uniform and stable performance can be obtained without any particular increase in width.

Since the power supply interval is controlled to increase or decrease, it is not affected by the frequency of the power supply unlike conventional methods, and regardless of whether the power supply is 50Hz or 60Hz, water discharge performance remains constant without any fluctuation in capacity. can be obtained, and there is no need to provide a frequency switching means or the like.

Even if the setting on the adjustment means is low, the capacity is reduced by variably adjusting the interval between power feedings, so the amount of water discharged will decrease, but the longer the energization cycle is, the more the flow of water will be accompanied by the plunger operation of the electromagnetic pump. The pulsating action of the running water becomes noticeable, and a higher cleaning effect can be obtained compared to a constant pressure water stream with the same amount of work.

Furthermore, the feeling of use is instantaneous even when a fairly high water pressure is generated at the peak due to the pulsating flow, so even sensitive people such as those with hemorrhoids can wash their private parts without feeling much pain.

Furthermore, if the power supply interval to the electromagnetic pump is varied and at the same time the unit time of power supply is controlled to be varied in proportion to the increase/decrease in this interval, the lower the water flow rate and water pressure, which increases the plunger operation load of the electromagnetic pump, the lower the water pressure. Since the power supply time is longer and full-stroke plunger operation is always obtained, uniform operating performance can be guaranteed without producing large machine differences compared to conventional phase control methods.
