Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a sanitary cleaning device for discharging cleaning water onto parts of the human body to be cleaned.

Structure of a conventional example and its problems A conventional sanitary cleaning device will be explained with reference to FIGS. 1 to 3.

Fig. 1 is a configuration diagram of a conventional sanitary washing device, in which 1 is a toilet seat installed in the toilet bowl, 2 is a toilet that stores water for flushing the inside of the toilet bowl, and 3 is a human body to be cleaned while sitting on the toilet seat 1. 4 is a water filter submerged in the water in the distiller 2; 5 is a water heater for storing the washing water and heating it to an appropriate temperature; 6 is a water filter for discharging washing water through the water filter 4; The water in the distiller 2 is sucked and fed under pressure to the water heater 5, and the hot water in the hot water Δ) 1 is transferred to the nozzle/I/3.
This is a pump that discharges FK purified water under pressure, and has a built-in motor as a driving source. 7 is a hot air outlet that blows out warm air to dry the parts to be cleaned that are sticky with cleaning water; 8 is a wind tunnel; 9 is a fan that blows air through the wind tunnel 8 to the hot air blowing lower section 11; A motor that drives the fan; 11 a heater that heats air from the fan to an appropriate temperature; 12 the water heater 6, the pump 6, and the motor 10;
, a control means for controlling the heater 11, etc., 13 is an operation section of the control means, and 14 is a storage box for storing each of the above-mentioned functions.

FIG. 2 is a front external view of the operating unit 13 in the conventional example, 15 is a variable resistor which is a means for setting the amount of washing water discharged, 16 is a switch for switching the drying temperature, and 17 is turned off each time it is pressed. It is an operation switch that sequentially sends a sequence from a state to a state in which the pump 6 is energized to perform cleaning, a state in which the heater 11 is energized and the motor 10 is simultaneously driven to perform drying, and then to an OFF state again, A ring counter and a driver (
(none of which are shown), each state is sequentially obtained. Reference numeral 18 denotes a lamp for displaying the state obtained by the operation switch 17, and the illustration shows the OFF state.

In the above configuration, when the user sitting on the toilet seat 1 wants to clean the toilet seat 1, when the user presses the operation switch 17, the lighting of the status display lamp 18 changes from OFF to cleaning, and the control means 12 In response to the command, the pump 6 is energized with the value set by the wash water release amount setting variable resistor 15, and the part to be cleaned is washed with a predetermined wash water release amount.

When you want to dry after washing, press the operating switch 17 again and the status display lamp 18 will turn on from washing to drying, the pump 6 will be deenergized, and at the same time the drying temperature changeover switch will switch off. The heater 11 is energized with the value set in step 16, and the motor 10 is driven to rotate the fan 9 to blow warm air from the warm air blowing lower towards the part of the human body to be cleaned that has been wetted by the cleaning water. Blow dry. When it is desired to end the drying, when the operation switch 17 is pressed again, the display on the status display lamp 18 changes from drying to OFF, and the energization of the heater 11 and motor 1o is stopped.

The above configuration allows the user to avoid multiple complicated operations, such as operating a cleaning switch when cleaning, turning off the cleaning switch and then turning on a drying switch when drying. Because all operations are completed by opening the door and operating just one switch, it is easy to operate and easy to remember, so it is especially useful for equipment that is used by the whole family, from children to the elderly, such as sanitary cleaning equipment. Although its advantages are taken advantage of, this configuration presents new problems. Unlike the old model, the operating part for the cleaning function is independent. For example, if you use a variable resistor with a switch and turn it clockwise, the switch turns on and the pump is activated. At the same time, the amount of cleaning water released is small. There was no problem with a configuration in which the amount of cleaning water discharged increases when the amount of cleaning water is discharged and the amount of cleaning water discharged is increased when the rotation is further turned to the right. switch 17 that energizes
In a configuration in which these are independent, the moment the switch 17 is pressed, the washing water discharge amount setting variable resistor 16
A set amount of cleaning water is discharged from the nozzle 3,
Since it hits the part of the human body to be cleaned, the user feels a sudden discomfort.

FIG. 3 shows a characteristic diagram of the time elapsed and the amount of washing water released. to is the time when the operation switch 1a is turned on to start cleaning, and the amount of cleaning water released is immediately equal to the set amount S.
stand up to s.

In the above configuration, in particular, the variable resistor 16 is set at a position not intended by the user, and when the user starts cleaning without noticing this, the user feels uncomfortable. This is especially true if the user has hemorrhoids.

OBJECT OF THE INVENTION The present invention solves the problems of the prior art, and allows the user to release washing water according to his or her preference without causing sudden discomfort to the user when starting washing. The purpose is to provide leeway for setting the amount.

Structure of the Invention To achieve this object, the present invention provides a low constant energization that is different from the set value of the variable resistor 16, which is the washing water discharge amount setting means, after the pump 6, which is the washing water discharge means, is turned on. The pump 6, which is the washing water discharging means, is controlled for a certain period of time with an energization amount that gradually increases from a low set value toward the set value, and after a certain period of time has elapsed, the energization is determined by the set value. A control means for controlling the pump 6 according to the amount is provided.

With this configuration, immediately after the pump is energized, the cleaning water hits the area to be cleaned in a soft manner, unlike the setting, eliminating the sudden sensation that the user felt immediately. This allows for comfortable washing with the amount of washing water discharged according to the user's preferred settings. The user can easily set the variable resistor, which is the setting means, for a certain period of time, for example, 5 seconds, from immediately after the pump is energized until the pump is energized according to the set value. Since you can adjust the position to your preference, you can always wash according to your preference. In addition, when the value is gradually increased toward the setting value, a particularly natural feeling of cleaning α1 can be obtained, and it has the advantage that it is easy to notice mistakes in the set value while the value is still gradually increasing, and it is easy to correct it.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 4 to 7.

FIG. 4 is a characteristic diagram of the amount of cleaning water discharged over time in one embodiment of the sanitary cleaning device of the present invention, and shows the characteristics of the operating switch 17.
When cleaning is started by turning ON at time to, a small cleaning water discharge amount S is different from the discharge amount Ss set by the variable resistor 15.
O is released to gently clean the area to be cleaned, and at the time ts, the release amount is automatically changed to the set release amount Ss.

Figure 6 shows the cleaning water discharge means (pump) in the above embodiment.
The following circuit diagram is shown. 19 is a power supply circuit, which is a full-wave rectified voltage VD that is cut at a constant voltage from an AC power supply VAC.
and a DC voltage Vcc. It is a switching circuit using a 20-digit timer. 21 is a timer capacitor, 2
2 is an operational amplifier, 23 + 24 is a 1-ransynuta for switching, and 25 is a relatively large value, and the 1-ransynuta 2
This is a resistor that supplies a base current of 4. 25 is a circuit for controlling the amount of energization of the pump 6, 26 is a resistor that switches with the variable resistor 16, 27 is a trigger element, 28 is a pulse transformer, and 29 is a power control element.

In the configuration described above, when the operation switch 17 is turned on, the potential of the capacitor 21 is zero at that moment, so the output of the operational amplifier 22 becomes Low, and the transistor 23 is turned on and the transistor 24 is turned off. Connect resistor 26 to VD. Therefore, the motor 6 is energized at a value determined by the resistor 26, regardless of the value of the variable resistor 15, and performs gentle cleaning. When the potential of the capacitor 21 rises after a certain period of time and the output of the operational amplifier 22 becomes Hi, the 1-range metal 23
is OFF, the above-mentioned Toy Shinu F 24 is ON,
The variable resistor 15 is connected to Vn instead of the resistor 26. The value of the resistor 25 is determined by the iTJ resistor 15.
By setting the value sufficiently larger than the value of , the resistor 26 becomes almost equal to a cut-off state. Therefore, the motor 6 is energized in a manner determined by the value of the variable resistor 15.

In the above configuration, the user does not suddenly feel uncomfortable when cleaning starts, and even after cleaning starts, the user has enough room to set the variable resistor to the amount of cleaning water discharged to his/her preference. This allows for comfortable washing by adjusting the amount of washing water discharged as desired.

FIG. 6 is a characteristic diagram of the elapsed time and amount of cleaning water released in another embodiment of the sanitary cleaning device of the present invention.
7 is turned on at time to to start cleaning, the cleaning water discharge amount S is smaller than the discharge amount Ss set by the variable resistor 15.
L is released to gently clean the area to be cleaned, and the amount of washing water released increases with the passage of time, and automatically reaches the set amount of water to be released Ss when the time reaches 1U.

FIG. 7 shows the washing water discharge means (pump) in the above embodiment.
The energizing circuit diagram is shown. Components with the same numbers as those in FIG. 5 are the same parts, so explanations thereof will be omitted.

30 is a potential lowering circuit using a timer, and 31 is a diode. The operational amplifier 22 constitutes a voltage follower circuit. 32.33 is a resistance for obtaining the base potential Vs.

In the configuration described above, when the operation switch 17 is turned on, the electric charge of the capacitor 26 is zero at that moment, so the potential Vll becomes a value close to Vcc, and therefore the resistor 3
The potential Vs originally determined by 2.33 is raised to the potential VK. Therefore, the energizing amount of the pump 60 becomes a value much smaller than the energizing amount originally determined by the variable resistor 15, and gentle cleaning is started. As time passes, the capacitor 21 is charged more and the potential Vt decreases, but the potential Vs also decreases accordingly, and the motor 6
3. The amount of bias increases. After a certain period of time has passed, the potential Vl is lower than the potential Vs originally obtained by the resistors 321 to 33.
Since the diode 31 is reverse-biased, Vs does not fall any further, and from then on, the cleaning is performed with a force determined by the variable resistor 15. .

In addition to the features of the previous example, the above configuration has the feature that a more natural cleaning feeling can be obtained by continuously changing the amount of cleaning water released, and it is still gradually increasing the possibility of incorrect setting values. It has the characteristics of being easy to change and correct.

Effects of the Invention As described above, the sanitary washing device of the present invention, after the washing water discharging means is turned on, energizes the washing water discharging means with a constant energizing amount different from the set value or from a low set value toward the set value. controlling the washing water discharge means for a certain period of time with a biasing amount that gradually increases;
Since a control means is provided for controlling the washing water discharge means with an energization amount determined by the set value after a certain period of time has elapsed,
Immediately after energizing the cleaning water discharge means, the cleaning water hits the area to be cleaned in a soft manner, unlike the setting, so the sudden discomfort that the user feels immediately after starting cleaning is eliminated, and moreover, after a certain period of time has elapsed. Afterwards, it has the feature that you can perform comfortable washing with the amount of washing water discharged according to your preferred settings. In addition, the user can easily set the setting means for a certain period of time, for example, 5 seconds, from immediately after starting the gentle energization of the cleaning water discharge means until the energization is performed according to the set value (=I). It has the advantage that you can always wash it according to your preference because it has a margin that allows you to adjust the position to your preference.

However, when gradually increasing toward the set value, it is possible to obtain a more natural cleaning feeling due to continuous changes in the amount of water discharged, and there is no need to worry about mistakes in the set value during the gradual increase. It has the advantage of being easy to use and easy to modify.
