Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sanitary cleaning device for cleaning toilet bowls, bidets, etc., which cleans the parts to be cleaned after using the toilet.

A conventional sanitary cleaning device has a configuration as shown in FIG. That is, 1 is a toilet seat, 2 is a washer body, 3 is a cleaning nozzle for discharging cleansing water to the area to be cleaned of a user sitting on the toilet seat 1, and 4 is a water supply for flushing the inside of the washer body 2. A cistern to store, 5, water stored in the cistern 4, 6
is a water filter provided in the cistern, and this water filter 6 is submerged in water 5. 7, 8, 9, and 10 are hoses; 11 is a pump that sucks water from the water filter 6 and pumps it to the cleaning nozzle 3; 12 is a tank that stores cleaning water;
13 is a heater that heats the cleaning water in the tank 12 to the optimum temperature for cleaning; 14 is a water valve that operates together with the pump 11 to open and close the cleaning water supply channel;
15 is a controller for controlling the pump 11, heater 13, water valve 14, and 16 is a storage box for storing the pump 11, tank 12, water valve 14, controller 15, etc.

In the conventional configuration shown in FIG. 1 above, after the user finishes using the toilet, the user opens the water valve 14 and at the same time energizes the pump 11 to clean the water stored in the tank 12 at an appropriate temperature. Since water is forced into the cleaning nozzle 3 and discharged, the user's area to be cleaned is thereby cleaned.

However, in the above-mentioned conventional configuration, the cold washing water accumulated in the hoses 9, 10 and the water valve 14 is released at the initial stage of washing water discharge, so that the cold water is instantaneously applied to the part to be cleaned. This has the disadvantage of causing discomfort to the user.

The present invention solves the above-mentioned drawbacks of the conventional method in which cold water hits the user's area to be cleaned by adding a control means to discard the accumulated water into the washer body at the initial stage of discharging the cleaning water, thereby making cleaning more comfortable. This is what I did.

Hereinafter, one embodiment of the present invention will be described based on FIGS. 2 to 7.

FIG. 2 shows a control circuit diagram of a pump of a sanitary cleaning device according to an embodiment of the present invention, in which 17 is a power source, 18 is a cleaning switch for starting cleaning, 1
9 is a timer circuit, 20 is a capacitor, 2
1 is a comparator. 22 is a phase control circuit that controls the amount of power supplied to the pump 11; 23 is a resistor;
4 is a transistor, 25 is a resistor, 26 is a trigger element, and 27 is a power control element. Note that the water valve 14 is energized in conjunction with the cleaning switch 18,
The heater 13 that always heats the cleaning water in the tank 12 to an appropriate temperature is omitted.

In the circuit configuration shown in FIG. 2, when the user turns on the washing switch 18 after using the toilet, the phase control circuit 22 triggers the power control element 27 at a phase determined by the resistor 23, and during normal washing The pump 11 is energized with an amount of power supplied smaller than the amount of power supplied. Therefore, the cleaning water does not generate enough force to reach the user's part to be cleaned, but falls directly into the washer body 2 from near the cleaning nozzle 3. After a certain period of time has elapsed, the capacitor 20 of the timer circuit 19 is charged, the comparator 21 is inverted, the transistor 24 is turned on, and the resistors 23 and 25 are connected in parallel. This results in
The trigger phase angle of the power control element 27 advances to energize the pump 11 with the amount of power supplied during normal cleaning;
Cleaning is performed by discharging cleaning water onto the user's area to be cleaned. The delay time created by the timer circuit 19 is such that the pump 11, which is energized with a small amount of power, reduces the amount of water that is dumped into the washer body 2 and remains in the hoses 9, 10 and water valve 14. It is set to be larger than the amount of water. Therefore, after the cold accumulated water is reliably discarded into the washer body 2, warm cleaning water can be discharged to the user's area to be cleaned, and as a result, discomfort is eliminated. In addition, since the amount of retained water is extremely small (about 10 c.c.), the delay time caused by the timer circuit 19 is only a few seconds, so there is almost no problem in usability. moreover,
By making the timer delay time slightly longer than the above-mentioned time, even if the hoses 9, 10 and water valve 14 are cold, the cleaning water is discharged to the user's part to be cleaned after warming them. This increases comfort, especially in places that get cold easily, such as in cold regions.

FIG. 3 shows the top configuration of a sanitary washing device according to another embodiment of the present invention, and FIG.
The only difference is that .

FIG. 4 shows a control circuit diagram of the pump in the embodiment shown in FIG. 3. The difference from FIG. 2 is that a thermo circuit 29 is connected instead of the timer circuit 19.

In FIGS. 3 and 4, when the cleaning switch 18 is turned on, the pump 11 is controlled with a small amount of power supplied, as in the case of FIGS. The accumulated cold water is discarded into the washer body 2. The cold water is then discarded and the warm wash water in the tank 12 is used to clean the hoses 9, 10 and the water valve 14.
As the temperature of the cleaning water increases, the sensor 28 detects the rising temperature of the cleaning water, and the sensor 28 detects the rising temperature of the cleaning water.
The resistance value of 8 will go down. The sensor 28 then detects that the temperature of the washing water discarded in the washer main body 2 has risen to a temperature that does not feel cold.
When detected, the comparator 21 of the thermo circuit 29
is reversed, and the pump 11 is energized with the normal amount of power as described above, and discharges cleaning water to the user's part to be cleaned. Therefore, when the washing water is cold, it is automatically discarded into the washer main body 2, and when it becomes cold, the washing starts automatically.
Similar to the embodiment shown in the figures, cold water does not hit the user's area to be cleaned, resulting in increased comfort and reliable operation.

FIG. 5 shows a control circuit diagram of a pump in another embodiment of the sanitary washing device of the present invention. This will be explained using an improved version of Fig. 4. The configuration of the phase control circuit 22 is slightly different from that shown in FIG. The difference is that a transistor 31 that operates in reverse is connected. In addition,
32 is a base resistance of the transistor 31, which has a very large value.

In the circuit configuration shown in FIG. 5 above, when the user turns on the cleaning switch 18, since the transistor 24 is off in the same manner as described above, the transistor 31 is turned on, the resistor 23 is connected, and the cleaning water is turned on. into the washer body 2. When the sensor 28 detects that the cleaning water is warm, the comparator 21 is reversed. As a result, the transistor 24 is turned on, and the transistor 31 is turned off. As a result, the resistor 23
Since the variable resistor 30 is disconnected and the variable resistor 30 is connected, the user can clean the part to be cleaned with the amount of cleaning water set by the variable resistor 30. In this manner, at the initial stage of discharging the wash water, the amount of wash water determined by the resistor 23 is released regardless of the setting of the variable resistor 30, so that the cold water is reliably discarded into the washer main body 2, and the cold water is After the water runs out, the user can freely vary the amount of washing water using the variable resistor 30, making it very convenient to use.

FIG. 6 shows the structure of the cleaning nozzle portion in yet another embodiment of the sanitary cleaning device of the present invention, where 33 is a nozzle cap, which is hollow and whose tip is closed. 3
4 is a cleaning water spout provided in the nozzle cap 33, and 35 is a gear connected to the nozzle cap 33. 36 is a water pipe, this water pipe 3
6 is also hollow and supplies cleaning water to the nozzle cap 33. Further, the nozzle cap 33 and the water pipe 36 are water-sealed with an O-ring or the like and are rotatably connected. 37 is a water supply header that supplies water to the water pipe 36, and 38 is a fixture that fixes the water supply header 37 to the storage box 16. 39 is a gear that meshes with the gear 35, and 40 is the gear 3.
This is a motor that allows rotation of the motor 9 in forward and reverse directions. In addition,
The state shown in FIG. 6 shows a state in which cleaning water is being discharged to the washer main body 2 side.

FIG. 7 shows a control circuit diagram for the embodiment shown in FIG. 6, which is a modification of the one shown in FIG. 2. 41 is a motor drive circuit. 42
is a motor drive IC, and 43, 44, 4
5 and 46 are transistors. The motor drive IC 42 has an input _I1 and outputs _φ1 to _φ4 ,
When the voltage of the input I ₁ becomes High, the outputs φ ₁ and φ
₂ , the transistors 43 and 44 are turned on, and the motor 40 is rotated by a certain amount.
The cleaning water spout 34 shown in the figure is directed toward the user's area to be cleaned and its rotation is stopped. When the voltage of input I ₁ is low, outputs φ ₃ and φ ₄ are energized,
turning on the transistors 45 and 46 to reverse the motor 40 by a certain amount in the opposite direction;
The cleaning water spout 34 is directed toward the cleaning device main body 2 as shown in FIG.

In the circuit configuration shown in FIG. 7, when the user turns on the cleaning switch 18, since no charge is accumulated in the capacitor 20, the output of the comparator 21, that is, the motor drive
The input I ₁ of the IC 42 is in a low state, so the outputs φ ₃ and φ ₄ cause the transistors 45 and 46 to
is turned on, and the motor 40 is instantaneously reversed to direct the washing water spout 34 toward the washer main body 2 as shown in FIG. At the same time, the pump 11 is energized by the phase control circuit 22, so that the cleaning water is discharged to the washer body 2 side as shown in FIG. This prevents cold water from hitting the user's area to be cleaned. After a certain period of time has elapsed, when the potential of the capacitor 20 rises and reaches the set value, the input _I1 of the motor drive IC 42 becomes High, and the outputs _φ1 and _φ2 cause the transistors 43, 44 is turned on, the motor 40 is instantly rotated in the forward direction, and the cleaning water spout 34 is directed toward the user's part to be cleaned, as shown by the broken line in FIG. This is what we do.

The above configuration has the advantage that it is not necessary to weaken the amount of power supplied to the pump 11 even when discharging cold water into the washer body 2, so that the cold water can be disposed of quickly.

In addition to the embodiments described above, a damper is used to cover the cleaning water spout with the damper at the initial stage of discharging the cleaning water, so that the cleaning water hits the damper and is disposed of into the cleaning device body, and after a certain period of time, the damper is removed. It is possible to consider a configuration in which the cleaning water spout is energized to release the cover and discharge the cleaning water to the user's part to be cleaned, and is not limited to the above embodiment.

As is clear from the above description, the sanitary cleaning device of the present invention is provided with a control means for discharging the cleaning water to the cleaning device main body at the beginning of the discharge of the cleaning water.
At the beginning of the flushing water discharge, the cold flushing water that had accumulated in the flushing water passage is discarded into the washer body, and the warmed flushing water is discharged to the user's area to be cleaned. As a result, the discomfort caused by instantaneous cold water hitting the area to be cleaned, unlike in the past, is eliminated.
