[Means for Solving the Problems]
The sanitary washing device of the present invention comprises nozzle means for ejecting wash water toward a human body part, and a water supply pump for periodically supplying the wash water to the nozzle means by changing the water amount to a set high water amount and a set low water amount. In the region where the water volume is increased from the set low water volume to the set high water volume, the amount of water supplied from the water supply pump is supplied more than the set high water volume .
[0010]
Thereby, in the case of changing from a weak wash water amount to a strong wash water amount during the local body washing, the set wash water amount can be reached in a short time, and the wash water can be used efficiently.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Form state of the present invention, a water supply pump for supplying a nozzle means for injecting washing water toward the human body station unit, periodically changing the amount of water to set a low water volume and setting high water and washing water to said nozzle means And in a region where the water volume is increased from the set low water volume to the set high water volume, the amount of water supplied from the water supply pump is controlled to be larger than the set high water volume.
[0012]
Thereby, in the case of changing from a weak wash water amount to a strong wash water amount during the local body washing, the set wash water amount can be reached in a short time, and the wash water can be used efficiently.
[0013]
Further, in the sanitary washing apparatus configured as described above, by providing storage means for storing the number of rotations corresponding to at least one set amount of the plurality of wash water set high water amounts or the plurality of set low water amounts, The water supply pump can be controlled by the rotation speed of the selected storage means, and the cleaning water can be periodically supplied to the nozzle means in the set high water amount pattern and the set low water amount pattern that the user likes.
[0014]
In addition, when the amount of cleaning water is periodically changed, the storage unit stores a plurality of times required for one cycle of the cleaning water periodically supplied from the water supply pump to the nozzle unit, thereby selecting the selected time. It is possible to control the water supply pump as one cycle.
[0015]
Further, the feed water pump is configured to be able to adjust the amount of cleaning water supplied to the nozzle means according to the applied voltage value, and the control means adjusts the voltage value applied to the feed water pump so that the feed water pump is connected to the nozzle means. By adopting a configuration in which the amount of cleaning water supplied is adjusted, it is possible to perform local body cleaning in a short time, and it is possible to efficiently use the cleaning water stored in the water storage tank.
[0016]
Further, the water supply pump is configured to be able to adjust the amount of cleaning water supplied to the nozzle means by performing phase control of the applied voltage, and the control means performs water phase control by performing phase control of the voltage applied to the water supply pump. By adjusting the amount of cleaning water supplied to the nozzle means by the pump, it is possible to perform local body cleaning in a short time and to efficiently use the cleaning water stored in the water storage tank.
[0017]
【Example】
Embodiments of the present invention will be described below with reference to FIGS.
[0018]
Example 1
In FIG. 1, a water storage tank 3 and a water supply pump 4 are connected to a cleaning water supply path 2 leading to a cleaning nozzle 1 in order from the upstream side. The water in the water storage tank 3 is appropriately heated by heating means such as a heater.
[0019]
The control unit 5 includes a cleaning cycle setting unit 6 that increases / decreases the rotation speed of the water supply pump 4 at a predetermined cycle, and a cycle storage unit 7 that stores a plurality of cycles of the cleaning cycle setting unit 6.
[0020]
That is, the feed water pump 4 has its rotational speed increased or decreased in a predetermined cycle via the cleaning cycle setting unit 6 whose cycle is selected by the cycle storage unit 7, and accordingly, the cleaning water is in a strong and weak pulsation state from the cleaning nozzle 1. Will be erupted.
[0021]
FIG. 2 shows a state in which the washing water is ejected at that time, when the feed water pump 4 is rotating at a high speed, 1200 cc / min, and when the feed water pump 4 is rotating at a low speed, the low water volume is set at 800 cc / min. It is. The period at this time is selected to be 10 seconds.
[0022]
Therefore, in this embodiment, the period can be changed to 15 seconds or 7 seconds within the range stored in the period storage means 7, and at least one value of the high water amount and the low water amount is determined by the control means 5. Can be selected and adjusted within the range stored in the washing water amount storage means 8 provided in the apparatus.
[0023]
The stored value selection of the period storage means 7 and the washing water amount storage means 8 is operated by the operation means 9.
[0024]
By the way, in the structure of the said Example, a start-up time is inevitably required at the time of starting of the feed pump 4 and in the process of shifting from a low water amount to a high water amount.
However, if the rise time is long, the cycle between the high water amount and the low water amount cannot be shortened, and strong and weak pulsations may become uncertain, and an accurate cleaning effect may not be expected.
[0025]
The control means 5 temporarily increases the rotation speed of the water supply pump 4 so that the supply water amount becomes higher than the set high water amount at the time of starting and in the process of shifting from the low water amount to the high water amount.
[0026]
Therefore, the start-up characteristic at the time of start-up and in the process of shifting from a low water amount to a high water amount is improved, and it is possible to surely realize strong and weak pulsations and also to adjust the cycle accurately.
[0027]
The rotation speed increase of the feed pump 4 at the start and in the process of shifting from the low water volume to the high water volume is primarily performed at the maximum output, and when the set high water volume is reached, the rotation speed is decreased to the predetermined rotation speed. Can be considered. Of course, as long as the supply water amount is equal to or higher than the set high water amount, the maximum output as the rotation speed of the feed water pump 4 is not concerned.
[0028]
The rotation of the water supply pump 4 can be easily realized by means such as voltage control or phase control.
[0029]
In the above-described embodiment, the case where the washing water is ejected in a strong and weak pulsation state has been described. However, this spirit is not true, and there is an effect even at the start when the washing water is ejected in a predetermined amount without pulsation. Needless to say.
[0030]
(Example 2)
Figure 3 shows a second embodiment, the embodiment differs from the first, there is to the added cycle measurement unit 10 in association associated with the control means 5.
[0031]
In the example of FIG. 4, the cleaning cycle setting means 6 is configured to stop the water supply pump 4 when strong and weak pulsation is ejected for two cycles. As a result, the cleaning operation can be performed without waste.
[0032]
The set cycle in the cleaning cycle setting means 6 can be arbitrarily adjusted by operating the operation means 9.
[0033]
In FIG. 4, the high water volume is 1300 cc / min and the low water volume is 700 cc / min. However, if the stored value of the washing water volume storage means 8 is changed, these volumes can be changed, for example, the high water volume is 1200 cc / min. The low water volume can be set to 800 cc per minute.
[0034]
【The invention's effect】
According to the present invention, a nozzle means, in the sanitary washing apparatus equipped with a water feed pump for supplying the set amount of wash water to said nozzle means, for more than the set feed water quantity during increase of the amount of wash water Thus, the time from the start of cleaning until the cleaning water reaches the human body part can be shortened, and the cleaning water can be used efficiently.
