Description

Aspects of the present invention generally relate to sanitary cleaning equipment.

Conventionally, there is known a sanitary washing device (sanitary washing toilet seat) that is placed on a flush toilet and discharges washing water toward a local part of the user. For example, Patent Documents 1 and 2 describe a sanitary cleaning device having a piston for discharging cleaning water and a cylinder for accommodating the piston. This piston is urged in the backward direction by a spring or the like, and advances forward by the pressure of the water flowing into the cylinder.

Further, the sanitary cleaning device described in Patent Document 2 includes a cleaning unit driving device. This cleaning unit drive device reciprocates a cleaning unit having a cylinder or a piston in the front-rear direction by water pressure. This makes it possible to perform move cleaning or position adjustment of the cleaning unit.

The sanitary cleaning device may be installed in a toilet room or a hotel unit bath where an AC power outlet is not provided on the wall surface or the like.

In a sanitary cleaning device that is not connected to an AC power source (AC power source), a method using a battery as a drive source for move cleaning (movement of a nozzle that discharges cleaning water) can be considered. This battery is also used, for example, to drive a latching solenoid valve that controls the supply of wash water to the nozzle. In this case, if the remaining battery level is exhausted during the move cleaning, the solenoid valve cannot be driven, and the supply of cleaning water to the nozzle may not be stopped. That is, there arises a problem that the discharge of the washing water from the nozzle cannot be stopped.

On the other hand, a method of detecting the remaining battery level before starting the move cleaning and prohibiting the execution of the move cleaning when the remaining battery level is less than a predetermined value can be considered. However, the length of time that the move cleaning is performed varies greatly depending on the degree of local contamination and the like. Therefore, there is a peculiar circumstance that the amount of electric power consumed by one move cleaning is not constant. That is, even if the move cleaning is started when the remaining battery level is equal to or higher than the predetermined value, if the move cleaning is executed longer than expected, the remaining battery level is exhausted during the move cleaning and the discharge of the washing water is stopped. There is a risk that you will not be able to do it.

The present invention has been made based on the recognition of such a problem, and is a battery-powered sanitary cleaning device that is not connected to an AC power source. It is an object of the present invention to provide a sanitary cleaning device that can surely prevent such a situation.

The first invention is a battery-powered sanitary cleaning device that is used without being connected to an AC power supply, and includes a toilet seat, a nozzle that discharges cleaning water toward a local part of a user seated on the toilet seat, and electricity. A battery accommodating portion for accommodating the pond, a latch-type electromagnetic valve driven by the battery to switch between discharging and stopping the washing water from the nozzle, and a motor driven by the battery to move the nozzle. A control unit that is driven by the battery and controls the electromagnetic valve and the motor, and is capable of executing a move cleaning mode in which cleaning water is discharged while moving the nozzle, and the remaining amount of the battery. The control unit includes a battery remaining amount detecting means for detecting, a water discharge and water stop of the washing water from the nozzle, and an operation unit for operating the start and stop of the move cleaning mode. If the remaining amount of the battery is equal to or less than the first threshold value before the execution of the move cleaning mode, even if the operation unit starts the move cleaning mode, the operation of the move cleaning mode is prohibited. Prohibition, automatic move cleaning stop that stops the motor and automatically stops the movement of the nozzle after a predetermined time has elapsed from the start of execution of the move cleaning mode, without being based on the operation of the operation unit. The first threshold is the amount of power consumed from the start of the execution of the move cleaning mode to the completion of the execution of the automatic stop of the move cleaning, and the electromagnetic valve is closed from the open state. It is a sanitary cleaning device characterized in that it is set to a value larger than the total of the amount of power consumed when the state is set and the discharge of the cleaning water from the nozzle is stopped.

According to the sanitary cleaning device according to the first invention, the solenoid valve is driven by a battery, so that the user manually opens and closes the valve even in the sanitary cleaning device installed in a toilet without an AC power supply. It is possible to switch between spouting and stopping the washing water without doing so. Thereby, operability can be improved. Further, since the solenoid valve is a latch type, the solenoid valve consumes electric power only when switching between opening and closing. Therefore, the life of the battery can be extended.
Further, by providing the move cleaning mode that can be executed by the electric power of the battery, even when the sanitary cleaning device is installed in a toilet without an AC power source, the move cleaning having a massage effect can be performed.
Further, when the control unit executes the move cleaning prohibition and the move cleaning automatic stop, it is possible to reliably prevent a situation in which the remaining battery level is exhausted during the move cleaning and the discharge of the cleaning water cannot be stopped.

According to the second invention, in the first invention, the first threshold value is the amount of electric energy consumed from the start of the execution of the move cleaning mode to the completion of the execution of the automatic stop of the move cleaning, and the electromagnetic wave. From the sum of the amount of power consumed when the valve is opened and closed and the discharge of wash water from the nozzle is stopped, and the amount of power consumed when the electromagnetic valve is opened and closed multiple times. Is a sanitary cleaning device characterized in that it is set to a large value.

According to the sanitary cleaning device according to the second invention, even after the control unit prohibits the execution of the move cleaning mode, the normal cleaning mode, which is a basic function, can be executed a plurality of times, so that the remaining battery level is reduced and the battery is used. It is possible to make the user recognize that the replacement time is near at an early stage and surely. As a result, even if it takes a period of time for the user to replace the battery, the user can use the normal cleaning mode, which is a basic function, during that period.

According to a third aspect of the present invention, in the first or second invention, the control unit moves the nozzle to a predetermined position based on the operation of the operation unit while the nozzle is discharging washing water. The position adjustment mode to be stopped can be executed, and the first threshold value is the amount of electric energy consumed from the start of the execution of the move cleaning mode to the completion of the execution of the automatic stop of the move cleaning, and the electromagnetic wave. The amount of power consumed when the valve is opened to closed and the discharge of wash water from the nozzle is stopped, and the amount of power consumed when the position adjustment mode is executed for at least a predetermined time. It is a sanitary cleaning device characterized in that it is set to a value larger than the total.

Can be suppressed.

A fourth aspect of the present invention is the third aspect of the present invention, when the control unit becomes equal to or less than a second threshold value smaller than the first threshold value while the position adjustment mode is being executed. The position adjustment forced stop is executed by stopping the motor and forcibly stopping the movement of the nozzle without being based on the operation of the operation unit, and the second threshold value is set from the open state to the closed state of the electromagnetic valve. It is a sanitary cleaning device characterized in that it is set to a value larger than the amount of electric power consumed when the discharge of cleaning water from a nozzle is stopped.

According to the sanitary cleaning device according to the fourth invention, it is possible to reliably prevent a situation in which the remaining battery level is exhausted during the execution of the position adjustment mode and the discharge of the cleaning water cannot be stopped.

A fifth aspect of the invention further comprises, in any one of the first to fourth aspects, a flow rate adjusting valve driven by the battery and changing the flow rate of the washing water supplied to the nozzle, the control unit. In a state where the nozzle is discharging wash water, a flow rate adjustment mode for changing the flow rate of the wash water discharged from the nozzle can be executed based on the operation of the operation unit, and the first threshold value is the said. The amount of power consumed from the start of execution of the move cleaning mode to the completion of the execution of the automatic move cleaning stop, and the electromagnetic valve is closed from the open state to stop the discharge of cleaning water from the nozzle. The sanitary cleaning apparatus is characterized in that it is set to a value larger than the sum of the amount of power consumed when the flow rate is adjusted and the amount of power consumed when the flow rate adjustment mode is executed for at least a predetermined time. ..

According to the sanitary cleaning device according to the fifth invention, the user can change the water discharge to the desired flow rate by the flow rate adjustment mode even after the move cleaning is prohibited, so that the cleaning property of the normal cleaning mode after the move cleaning is prohibited is deteriorated. Can be suppressed.

A sixth aspect of the present invention is the fifth aspect of the present invention, when the control unit becomes equal to or less than a third threshold value smaller than the first threshold value while the flow rate adjusting mode is being executed. The operation of the flow rate adjusting valve is stopped without being based on the operation of the operation unit, and the forced stop of the flow rate adjustment for forcibly prohibiting the operation of the flow rate adjusting valve is executed. The sanitary cleaning device is characterized in that it is closed from the ground and is set to a value larger than the amount of electric power consumed when the discharge of the washing water from the nozzle is stopped.

According to the seventh aspect of the present invention, in any one of the first to sixth aspects, the predetermined time from the start of execution of the move cleaning mode to the stop of the movement of the nozzle can be changed. It is a characteristic sanitary cleaning device.

According to the sanitary cleaning device according to the seventh invention, the user can optimally set the time (move time) until the move cleaning mode is automatically stopped according to the situation. For example, if the battery can be replaced frequently, the move time can be lengthened to prioritize the improvement of cleanability, and if the battery cannot be replaced frequently, the move time can be shortened to shorten the battery life. Can be prioritized for improvement.

Eighth aspect of the present invention, in the seventh, wherein the control unit, when the remaining capacity of the battery before the execution of the move cleaning mode is greater than the fifth threshold value is a first threshold value greater than The predetermined time from the start of the execution of the move cleaning mode to the stop of the movement of the nozzle is set as the first time, and the remaining amount of the battery before the execution of the move cleaning mode is the fifth. When it is equal to or less than the threshold value, the predetermined time from the start of execution of the move cleaning mode until the movement of the nozzle is stopped is set to a second time shorter than the first time. It is a sanitary cleaning device.

It is a flowchart which illustrates the operation of the sanitary washing toilet seat which concerns on embodiment.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In each drawing, similar components are designated by the same reference numerals and detailed description thereof will be omitted as appropriate.

FIG. 1 is a perspective view illustrating a toilet device provided with a sanitary washing toilet seat according to the embodiment.
As shown in FIG. 1, the toilet device 200 has a sanitary washing toilet seat (sanitary washing device) 100 and a toilet bowl 150. The sanitary washing toilet seat 100 is provided on the toilet bowl 150. The toilet bowl 150 is, for example, a Western-style seated toilet bowl, and has a bowl 151 for receiving excrement of the user.

The sanitary washing toilet seat 100 has a functional unit 130 having a local washing unit 101, a casing 201, a toilet seat 202, and a toilet lid 203.
The local cleaning unit 101 has a nozzle (hydraulic cleaning nozzle 10) and is housed inside the casing 201. The hydraulic cleaning nozzle 10 has, for example, a water spout 10a at its tip, and when used, it advances to the bowl 151 as shown in FIG. 1 and from the water spout 10a, a local part of the user seated on the toilet seat 202 (for example, "" Discharge wash water toward the "buttocks" and women's local areas). The toilet seat 202 is rotatably supported by the casing 201. The toilet lid 203 is rotatably pivotally supported with respect to the casing 201 and can cover the toilet seat 202.

In the description of the embodiment, the front is referred to as "forward" when viewed from the user sitting on the toilet seat 202, and the direction opposite to the front is referred to as "rear".

FIG. 2 is a block diagram illustrating a sanitary washing toilet seat according to the embodiment.
As shown in FIG. 2, the sanitary washing toilet seat 100 according to the embodiment has a functional unit 130 and a battery accommodating unit 60. The functional unit 130 and the battery accommodating unit 60 are housed inside the casing 201 shown in FIG. 1, for example.

The functional unit 130 includes a solenoid valve 131, a flow rate adjusting valve (electric flow rate adjusting valve 132), a local cleaning unit 101, a control unit 70, and a battery remaining amount detecting means 71.
Water is supplied to the hydraulic cleaning nozzle 10 of the local cleaning unit 101 from a water supply source (water pipe or the like) 204. A water stop valve 205, a solenoid valve 131, and an electric flow rate adjusting valve 132 are arranged in this order from the upstream side in the flow path between the hydraulic cleaning nozzle 10 and the water supply source 204.

The solenoid valve 131 opens and closes the flow path to the hydraulic cleaning nozzle 10 to control water supply / stoppage to the hydraulic cleaning nozzle 10. As a result, the solenoid valve 131 switches between discharging and stopping the cleaning water from the hydraulic cleaning nozzle 10. A latch type solenoid valve is used as the solenoid valve 131. The latch type solenoid valve moves the plunger by energizing the solenoid coil to switch the open / closed state of the flow path. When the flow path is maintained open or closed, the solenoid valve utilizes the magnetic force of the permanent magnet or the elastic force of the spring to hold the plunger. On the other hand, when switching between the open state and the closed state (during driving), the solenoid valve is energized to move the plunger. Therefore, the solenoid valve need only be supplied with electric power when the flow path is switched between open and closed states.
The electric flow rate adjusting valve 132 adjusts (changes) the flow rate of the cleaning water supplied to the hydraulic cleaning nozzle 10 by adjusting the opening degree of the flow path to the hydraulic cleaning nozzle 10. For the electric flow rate adjusting valve 132, for example, a valve having a motor is used.

Further, the local cleaning unit 101 has a cleaning nozzle reciprocating motion means 20 in addition to the above-mentioned hydraulic cleaning nozzle 10. The cleaning nozzle reciprocating motion means 20 is connected to the hydraulic cleaning nozzle 10 and reciprocates the hydraulic cleaning nozzle 10. The cleaning nozzle reciprocating motion means 20 includes a motor 21 for moving the hydraulic cleaning nozzle 10. In this example, the motor 21 reciprocates the hydraulic cleaning nozzle 10 in the vertical direction. The motor 21 is, for example, a stepping motor or a servomotor. The reciprocating motion by the cleaning nozzle reciprocating motion means 20 (motor 21) will be described later.

The control unit 70 is electrically connected to the solenoid valve 131, the electric flow rate adjusting valve 132, and the motor 21. The control unit 70 is a control circuit including, for example, an IC element. The control unit 70 controls the operations of the solenoid valve 131, the electric flow rate adjusting valve 132, and the motor 21 by transmitting a signal.
Further, the control unit 70 includes a cleaning switching means 72, a position adjustment forced stop means 74, a flow rate adjustment forced stop means 75, a move cleaning prohibition means 76, a move automatic stop means 77, and a move time changing means 78. These will be described later.

The battery accommodating unit 60 accommodates a battery 61 that generates DC power and drives the functional unit 130 by the DC power. The solenoid valve 131, the electric flow rate adjusting valve 132, the motor 21, and the control unit 70 are driven by the electric power supplied from the battery 61. That is, the sanitary washing toilet seat 100 according to the embodiment is a battery-powered device that is used without being connected to an AC power source. As the battery 61, for example, a dry battery or a rechargeable battery (secondary battery, capacitor, etc.) is used. The battery accommodating unit 60 is, for example, a battery case (battery box), and the battery 61 is removable (replaceable) with respect to the battery accommodating unit 60.

The sanitary washing toilet seat 100 has an operation unit 80 for the user to operate the operation of the functional unit 130 (such as spouting and stopping the washing water from the nozzle and starting and stopping the move washing mode described later). The operation unit 80 has a plurality of buttons (stop button 81, buttocks cleaning button 82, bidet button 83, nozzle move button 84, position adjustment button 85, flow rate adjustment button 86). When the user presses any of these buttons, a signal corresponding to the pressed button is transmitted to the control unit 70. The control unit 70 controls the function unit 130 based on this signal. The communication between the operation unit 80 and the control unit 70 may be wired communication, or wireless communication by radio waves or infrared rays. The operation unit 80 may be a remote controller installed on the wall surface of the toilet room or the like, or may be attached to the casing 201 of the sanitary washing toilet seat 100.

3 (a) and 3 (b) are perspective views illustrating a local cleaning unit of the sanitary cleaning toilet seat according to the embodiment.
The hydraulic cleaning nozzle 10 has a nozzle body 11 provided with a water discharge port 10a, and a cylinder 12 for accommodating the nozzle body 11. The cylinder 12 has an inflow port 12a provided behind the cylinder 12. A hose or the like is connected to the inflow port 12a, and the water supplied from the water supply source 204 flows into the hydraulic cleaning nozzle 10 from the inflow port 12a.

The local cleaning unit 101 has a support portion 22 that supports the hydraulic cleaning nozzle 10. The support portion 22 is directly or indirectly fixed to the casing 201 of the sanitary washing toilet seat 100. The hydraulic cleaning nozzle 10 is supported by a support portion 22 and is rotatable around a rotation shaft Ax1 provided on the cylinder 12.

The motor 21 is connected to the cylinder 12. By transmitting the rotation (driving force) of the motor 21 to the cylinder 12, the hydraulic cleaning nozzle 10 can rotate about the rotation shaft Ax1 as shown by the arrow A1. The rotation shaft Ax1 extends along the direction D2 perpendicular and horizontal to the direction D1 in which the nozzle body 11 extends linearly. For example, the rotation axis Ax1 is parallel to the horizontal direction D2.

4 (a) to 4 (c) are cross-sectional views illustrating the operation of the hydraulic cleaning nozzle.
FIG. 4A shows a state (standby state) when the hydraulic cleaning nozzle 10 is not in use. At this time, water is not supplied to the hydraulic cleaning nozzle 10. As shown in FIG. 4A, the nozzle body 11 is housed in the cylinder 12 in the standby state.

The nozzle body 11 is urged rearward by a spring 13 provided inside the cylinder 12. Further, the nozzle body 11 has a tubular portion 11a and a closing portion 11e provided at the rear end thereof. In the standby state, the flow path 11b in the tubular portion 11a is closed by the closing portion 11e.

FIG. 4B shows a state when water starts to flow into the inflow port 12a. The water flows into the cylinder 12 and is supplied toward the nozzle body 11. Due to the water pressure, the nozzle body 11 advances from the cylinder 12 to the front (inside the bowl 151 of the toilet bowl 150) as shown in FIG. 4 (b). At this time, the flow path 11b of the tubular portion 11a remains closed by the closing portion 11e.

FIG. 4C shows a state in which water further flows into the inflow port 12a and the nozzle body 11 further advances forward (water discharge state). At this time, a gap is formed between the tubular portion 11a and the closing portion 11e, and water flows into the flow path 11b. As a result, the water spouting port 10a provided near the tip of the tubular portion 11a discharges the supplied water as the washing water W. When the inflow of water from the inflow port 12a is stopped, the water pressure in the hydraulic cleaning nozzle 10 drops, the urging force of the spring 13 becomes dominant, and the state returns to the standby state shown in FIG. 4A.

5 (a) to 5 (c) are side views illustrating the operation of the local washing unit of the sanitary washing toilet seat according to the embodiment. These figures represent the hydraulic cleaning nozzle 10 in the water discharge state. The control unit 70 has a move cleaning mode in which the local cleaning unit 101 executes the move cleaning, and a fixed cleaning mode in which the fixed cleaning is executed. The move cleaning means to discharge the cleaning water to the hydraulic cleaning nozzle 10 while moving the hydraulic cleaning nozzle 10. The fixed cleaning mode means that the cleaning water of the hydraulic cleaning nozzle 10 is discharged while the position of the hydraulic cleaning nozzle 10 is fixed.
Further, the control unit 70 (cleaning switching means 72) controls the motor 21 to switch between move cleaning and fixed cleaning.

In this example, in the move cleaning mode, the control unit 70 reciprocates the hydraulic cleaning nozzle 10 at a predetermined angle with the reference position P as the starting point by the motor 21 (cleaning nozzle reciprocating means 20), and moves the human body to the hydraulic cleaning nozzle 10. Discharge wash water locally.

More specifically, the control unit 70 moves the water discharge port 10a downward by rotating the motor 21 (forward rotation). As a result, the position of the hydraulic cleaning nozzle 10 (the position of the spout 10a) is set to the lower position PL shown in FIG. 5 (a). After that, the control unit 70 moves the water discharge port 10a upward by rotating the motor 21 in the reverse direction. As a result, the position of the hydraulic cleaning nozzle 10 (the position of the spout 10a) becomes the upper position PU shown in FIG. 5 (c) via the reference position P shown in FIG. 5 (b). After that, the control unit 70 rotates the motor 21 in the forward direction, and again sets the position of the hydraulic cleaning nozzle 10 as the lower position PL. In this way, the motor 21 alternately repeats forward rotation and reverse rotation to reciprocate the hydraulic cleaning nozzle 10 between the upper position PU and the lower position PL in the vertical direction. In the description of the embodiment, clockwise rotation in FIG. 5 is forward rotation and counterclockwise rotation is reverse rotation.

This reciprocating rotation changes the direction in which the washing water is discharged. For example, when the hydraulic cleaning nozzle 10 is in the lower position PL, the cleaning water is discharged forward as compared with the case where the hydraulic cleaning nozzle 10 is in the upper position PU.

Assuming that the angle of the hydraulic cleaning nozzle 10 in the state shown in FIG. 5 (b) is the cleaning standard angle (θ), the angle of the hydraulic cleaning nozzle 10 in the state shown in FIG. 5 (a) is, for example, θ + Δγ, and FIG. The angle of the hydraulic cleaning nozzle 10 in the state shown in (c) is, for example, θ−Δγ. The position of the hydraulic cleaning nozzle 10 when the angle of the hydraulic cleaning nozzle 10 is the standard cleaning angle (θ) is referred to as a reference position P. The hydraulic cleaning nozzle 10 reciprocates around the reference position P at an amplitude angle (Δγ). The angle of the hydraulic cleaning nozzle 10 is an angle at which the water discharge port 10a side of the hydraulic cleaning nozzle 10 rotates vertically downward from the horizontal plane H. Δγ is, for example, about 0.5 ° or more and 5 ° or less.

On the other hand, in the fixed cleaning, the control unit 70 causes the hydraulic cleaning nozzle 10 to discharge the local cleaning water to the human body in a state where the position of the hydraulic cleaning nozzle 10 is fixed. For example, the fixed wash is performed at the reference position P.

Further, the reference position P changes depending on the cleaning target. For example, the reference position P is the reference position PA for cleaning the buttocks used for cleaning the buttocks, or the reference position PB for the bidet (reference position for cleaning the female local area) used for cleaning the female local area (bidet). For example, when the user presses the buttocks cleaning button 82, the control unit 70 sets the standard cleaning angle (θ) to the buttocks cleaning standard angle (φA), so that the reference position P becomes the buttocks cleaning reference position PA. When the user presses the bidet button 83, the control unit 70 sets the standard cleaning angle (θ) to the bidet standard angle (φB), so that the reference position P becomes the bidet reference position PB. Further, the reference position P may be appropriately adjusted by the user by the position adjustment button 85 of the operation unit 80.

Further, the control unit 70 moves the hydraulic cleaning nozzle 10 based on the operation of the operation unit 80 by the user in a state where the hydraulic cleaning nozzle 10 is discharging the cleaning water, and at a predetermined position P'. It has a position adjustment mode to stop. For example, each time the position adjustment button 85 is pressed, the control unit 70 rotates the motor 21 to rotate the hydraulic cleaning nozzle 10 by a predetermined angle (+ Δθ or −Δθ) as shown in FIG. 5 (b). Let me.

Further, the control unit 70 changes the flow rate of the cleaning water discharged from the hydraulic cleaning nozzle 10 based on the operation of the operation unit 80 by the user while the hydraulic cleaning nozzle 10 is discharging the cleaning water. It has a flow rate adjustment mode. For example, each time the flow rate adjusting button 86 is pressed, the control unit 70 controls the motor of the electric flow rate adjusting valve 132 to increase or decrease the flow rate of water supplied to the hydraulic cleaning nozzle 10 by a predetermined amount. This predetermined amount is arbitrary and is appropriately determined in consideration of the usability of the user.

In the above, the case where the hydraulic cleaning nozzle 10 reciprocates in the vertical direction is given as an example, but the movement of the hydraulic cleaning nozzle 10 is not limited to the reciprocating rotation. For example, a method (linear motion type) in which the nozzle body 11 moves linearly along the direction in which the nozzle extends linearly may be adopted. Further, the nozzle for discharging the washing water is not limited to the hydraulic type, and may advance or retreat by, for example, the electric power supplied from the battery.

According to the sanitary washing toilet seat 100 described above, the electromagnetic valve 131 is driven by the battery 61, so that the user can discharge the washing water without manually opening and closing the valve even when there is no AC power supply. You can switch the water stop. Thereby, operability can be improved. Further, since the solenoid valve 131 is a latch type, the solenoid valve 131 consumes electric power only when switching between opening and closing, so that the life of the battery 61 can be extended. Further, by providing the move cleaning mode that can be executed by the electric power of the battery 61, it is possible to perform the move cleaning having a massage effect even when there is no AC power supply.

By the way, a battery generally has a limited life, and the remaining amount of electric power that can be supplied by the battery 61, that is, the remaining amount of the battery, decreases with the lapse of the usage period. Therefore, for example, if the remaining battery level is exhausted during the move cleaning, the latch type solenoid valve cannot be driven, and the discharge of the cleaning water from the nozzle may not be stopped. On the other hand, the control unit 70 in the embodiment prevents the discharge of the washing water from being unable to be stopped by performing control according to the remaining amount of the battery 61.

The control based on the remaining amount of the battery 61 will be described with reference to FIGS. 6 (a) and 6 (b).
6 (a) and 6 (b) are graphs and tables illustrating the operation of the sanitary washing toilet seat according to the embodiment.
The vertical axis of FIG. 6A represents the remaining amount of the battery 61, and the horizontal axis represents the usage period (elapsed time). Regarding the remaining amount of the battery 61, the first to fifth threshold values Vt1 to Vt5, which are smaller than the remaining amount immediately after the battery replacement, are provided.

The remaining amount of the battery 61 in the period P1 is larger than the fifth threshold value Vt5.
In the period P2, the remaining amount of the battery 61 is larger than the first threshold value Vt1 and equal to or less than the fifth threshold value Vt5.
In the period P3, the remaining amount of the battery 61 is larger than the second threshold value Vt2 or the third threshold value Vt3 and equal to or less than the first threshold value Vt1.
In the period P4, the remaining amount of the battery 61 is larger than the fourth threshold value Vt4 and equal to or less than the second threshold value Vt2 or the third threshold value Vt3.
In the period P5, the remaining amount of the battery 61 is equal to or less than the fourth threshold value Vt4.
In this example, the second threshold value Vt2 and the third threshold value Vt3 have the same value but may be different values.

Further, the remaining amount of the battery 61 is detected by the battery remaining amount detecting means 71. For example, the battery remaining amount detecting means 71 has an electric circuit, and can detect the remaining amount of the battery 61 by the output voltage of the battery 61. In this case, five thresholds relating to the output voltage of the battery 61 are provided corresponding to the first to fifth thresholds Vt1 to Vt5, and the control unit 70 controls according to the output voltage of the battery 61. Further, the control unit 70 constantly acquires, for example, the remaining amount (output voltage value) of the battery 61. The battery remaining amount detecting means 71 may be a part of the control unit 70, or may be provided separately from the control unit 70. The means for measuring the output voltage of the battery 61 (such as a voltmeter) may be included in the battery remaining amount detecting means 71, or may be provided separately.

The control unit 70 limits the functions of the functional unit 130 according to the acquired information on the remaining amount of the battery 61. FIG. 6B shows the functions that the functional unit 130 can perform in each period. "○" indicates that it is feasible, and "x" indicates suspension or prohibition.

For example, the remaining amount of the battery 61 may be equal to or less than the first threshold value Vt1 before the move cleaning mode is executed. That is, the remaining battery level may be in any of the periods P3, P4, and P5 before the move cleaning is executed. At this time, the control unit 70 (move cleaning prohibiting means 76) executes the move cleaning prohibition. That is, the control unit 70 prohibits the move cleaning mode even if the operation unit 80 starts the move cleaning mode.

Further, when the move cleaning mode is started, the control unit 70 (mov automatic stop means 77) executes the move cleaning automatic stop. That is, the control unit 70 stops the motor 21 without being based on the operation of the operation unit 80 after a predetermined time (hereinafter, may be referred to as “move time”) elapses after the execution of the move cleaning mode is started, and the hydraulic type The movement of the cleaning nozzle 10 is automatically stopped.

The first threshold value Vt1 is the electric energy of the battery 61 consumed from the start of the execution of the move cleaning mode to the completion of the execution of the automatic stop of the move cleaning, and the solenoid valve 131 is set from the open state to the closed state. The value is set to be larger than the total of the electric energy of the battery 61 consumed when the discharge of the washing water from the hydraulic washing nozzle 10 is stopped.

As described above, in the embodiment, the control unit 70 executes the automatic stop of the move cleaning, so that the maximum amount of electric power consumed in one move cleaning can be limited. Then, the control unit 70 executes the move cleaning prohibition when the remaining amount of the battery 61 is equal to or less than the first threshold value. That is, if there is a risk that the remaining amount of the battery 61 will be less than the amount of electric power that can stop the water discharge when the move cleaning is performed, the control unit 70 does not execute the move cleaning mode. As a result, it is possible to reliably prevent a situation in which the remaining amount of the battery 61 is exhausted during the move cleaning and the discharge of the cleaning water cannot be stopped.

Further, the first threshold value Vt1 is the electric energy of the battery 61 consumed from the start of the execution of the move cleaning mode to the completion of the execution of the automatic stop of the move cleaning, and the electromagnetic valve 131 is set from the open state to the closed state. More than the sum of the electric energy of the battery 61 consumed when the discharge of the cleaning water from the hydraulic cleaning nozzle 10 is stopped and the electric energy of the battery 61 consumed when the electromagnetic valve 131 is opened and closed a plurality of times. It may be set to a large value.

The electric power of the battery 61 consumed when opening and closing the solenoid valve 131 a plurality of times is an electric energy capable of performing each of the opening operation and the closing operation of the solenoid valve 131 at least twice. As a result, the control unit 70 can execute the fixed cleaning mode (normal cleaning mode), which is a basic function, a plurality of times even after the execution of the move cleaning mode is prohibited. Further, by setting the first threshold value Vt1 to such a value, the time when the move cleaning mode is prohibited becomes earlier, so that the remaining amount of the battery 61 becomes low and the battery replacement time is approaching early and surely. It can be recognized by the user. Even if it takes a period of time for the user to replace the battery, the user can use the fixed cleaning mode, which is a basic function, during that period.

Further, as shown in FIG. 6B, during the period P3, the control unit 70 does not execute the move cleaning mode, but can execute the position adjustment mode.
In this case, the first threshold value Vt1 is the electric energy of the battery 61 consumed from the start of the execution of the move cleaning mode to the completion of the execution of the automatic stop of the move cleaning, and the electromagnetic valve 131 from the open state to the closed state. The electric energy of the battery 61 consumed when the discharge of the cleaning water from the hydraulic cleaning nozzle 10 is stopped, and the electric energy of the battery 61 consumed when the position adjustment mode is executed for at least a predetermined time. It is set to a value larger than the total of. The predetermined time is a length that allows the angle of the hydraulic cleaning nozzle 10 to be adjusted about 100 times in the range of 0.1 to 0.5 degrees, for example, 1 second or more and 5 seconds or less. Even if the position adjustment is performed about 5 times per cleaning, the fixed cleaning can be performed 20 times while performing the position adjustment.

That is, when the remaining amount of the battery 61 becomes equal to or less than the first threshold value Vt1, the control unit 70 prohibits the move cleaning in a state where the electric power capable of stopping the water discharge and adjusting the position of the hydraulic cleaning nozzle 10 remains in the battery 61. Execute. As a result, even after the move cleaning is prohibited, the user can change the water discharge to a desired position by the position adjustment mode, so that it is possible to suppress the deterioration of the cleaning property of the fixed cleaning mode after the move cleaning is prohibited. Further, by leaving the position-adjustable electric power for a plurality of times, fixed cleaning can be performed while performing the position adjustment a plurality of times, and the user can replace the battery with a margin.

Further, for example, the remaining amount of the battery 61 may become the second threshold value Vt2 or less during the execution of the position adjustment mode. That is, the remaining battery level may change from the state of the period P3 to the state of the period P4 during the execution of the position adjustment mode. At this time, the control unit 70 (position adjustment forced stop means 74) stops the motor 21 and forcibly stops the movement of the hydraulic cleaning nozzle 10 without being based on the operation of the operation unit 80 by the user. Perform a forced stop.

The second threshold value Vt2 is smaller than the first threshold value Vt1, and the power of the battery consumed when the solenoid valve 131 is closed from the open state and the discharge of the cleaning water from the hydraulic cleaning nozzle 10 is stopped. It is set to a value larger than the amount.

That is, when the remaining amount of the battery 61 becomes equal to or less than the second threshold value Vt2, the control unit 70 forcibly stops the position adjustment mode with the electric power capable of stopping the water discharge remaining in the battery 61. As a result, it is possible to reliably prevent a situation in which the remaining battery level is exhausted during the execution of the position adjustment mode mode and the discharge of the washing water cannot be stopped.

Further, in the period P3, the control unit 70 can execute the flow rate adjustment mode. In this case, the first threshold value Vt1 is the electric energy of the battery 61 consumed from the start of the execution of the move cleaning mode to the completion of the execution of the automatic stop of the move cleaning, and the electromagnetic valve 131 from the open state to the closed state. The electric energy of the battery 61 consumed when the discharge of the cleaning water from the hydraulic cleaning nozzle 10 is stopped, and the electric energy of the battery 61 consumed when the flow rate adjustment mode is executed for at least a predetermined time. It is set to a value larger than the total. The predetermined time is, for example, a length that allows the flow rate to be changed at least 40 times or more, and is, for example, 10 seconds or more and 20 seconds or less. Even if the flow rate is changed about twice per cleaning, fixed cleaning can be performed 20 times while adjusting the flow rate.

That is, when the remaining amount of the battery 61 becomes equal to or less than the first threshold value Vt1, the control unit 70 executes the move cleaning prohibition in a state where the battery 61 has electric power capable of stopping the water discharge and adjusting the flow rate of the washing water. As a result, even after the move cleaning is prohibited, the user can change the water discharge to the desired flow rate by the flow rate adjustment mode, so that it is possible to suppress the deterioration of the cleaning property of the fixed cleaning mode after the move cleaning is prohibited. Further, by leaving the power that can adjust the flow rate for a plurality of times, fixed cleaning can be performed while performing the position adjustment a plurality of times, and the user can replace the battery with a margin.

Further, for example, the remaining amount of the battery 61 may become the third threshold value Vt3 or less during the execution of the flow rate adjustment mode. That is, the remaining battery level may change from the state of the period P3 to the state of the period P4 during the execution of the flow rate adjustment mode. At this time, the control unit 70 (flow rate adjustment forced stop means 75) stops the operation of the electric flow rate adjusting valve 132 and forcibly operates the electric flow rate adjusting valve 132 without being based on the operation of the operation unit 80 by the user. Forcibly stop the flow rate adjustment.

The third threshold value Vt3 is smaller than the first threshold value Vt1, and the power of the battery consumed when the solenoid valve 131 is closed from the open state and the discharge of the cleaning water from the hydraulic cleaning nozzle 10 is stopped. It is set to a value larger than the amount.

That is, when the remaining amount of the battery 61 becomes equal to or less than the third threshold value Vt3, the control unit 70 forcibly stops the flow rate adjustment mode with the electric power capable of stopping the water discharge remaining in the battery 61. As a result, it is possible to reliably prevent a situation in which the remaining battery level is exhausted during the execution of the flow rate adjustment mode and the discharge of the washing water cannot be stopped.

Further, in a state where the hydraulic cleaning nozzle 10 does not move and the cleaning water is discharged, the remaining amount of the battery 61 may be the fourth threshold value Vt4 or less. That is, for example, at the time of fixed cleaning, the remaining battery level may change from the state of the period P4 to the state of the period P5. At this time, the control unit 70 executes forced water stoppage in which the solenoid valve 131 is closed and the discharge of the cleaning water from the hydraulic cleaning nozzle 10 is forcibly stopped without being based on the operation from the operation unit 80. ..

The fourth threshold value Vt4 is smaller than the first to third threshold values Vt1 to Vt3, and is consumed when the solenoid valve 131 is closed from the open state and the discharge of the cleaning water from the hydraulic cleaning nozzle 10 is stopped. The value is set to be larger than the electric energy of the battery 61.

Even when the motor 21, the solenoid valve 131, the electric flow rate adjusting valve 132, or the like is not driven by the battery 61, the power of the battery 61 continues to be slightly consumed by the control unit 70 or the like. On the other hand, in the embodiment, when the remaining amount of the battery 61 becomes the fourth threshold value Vt4 or less in the water discharge state, the water pressure type cleaning nozzle 10 is used while the battery 61 still has the electric power to stop the water discharge for cleaning. The spouting of the washing water is forcibly stopped. As a result, it is possible to reliably prevent a situation in which the remaining battery level is exhausted during the discharge of the cleaning water and the discharge of the cleaning water from the nozzle cannot be stopped.

Further, the length of the move time (a predetermined time from the start of the execution of the move cleaning mode to the stop of the movement of the nozzle) in the automatic stop of the move cleaning may be changeable. For example, when the user sends a setting change signal to the control unit 70 using the operation unit 80 or the like, the control unit 70 (move time changing means 78) changes the move time based on the signal. As a result, the user can optimally set the move time according to the situation. For example, if the battery can be replaced frequently, the move time can be lengthened to prioritize the improvement of cleanability, and if the battery cannot be replaced frequently, the move time can be shortened to shorten the battery life. Can be prioritized for improvement.

Further, the control unit 70 may change the move time according to the remaining amount of the battery 61. For example, when the remaining amount of the battery 61 is a value larger than the fifth threshold value Vt5 (first value) as in the period P1, the control unit 70 sets the move time to a relatively long time (first value). Time). On the other hand, when the remaining amount of the battery 61 is a value equal to or less than the fifth threshold value Vt5 (a second value smaller than the first value) as in the period P2, the control unit 70 relatively sets the move time. Let it be a short time (a second time shorter than the first time). As a result, the control unit 70 improves the cleaning property by lengthening the move time when the remaining amount of the battery 61 is large, and improves the battery life by shortening the move time when the remaining amount of the battery 61 is low. Therefore, it is possible to achieve both improvement in cleanability and improvement in battery life.

The length of the move time (first time, second time) is arbitrary and is appropriately determined in consideration of the usability of the user and the like, and is, for example, about 20 seconds or more and 60 seconds or less.

A specific example of the operation of the sanitary washing toilet seat 100 according to the embodiment will be further described with reference to FIG. 7.
FIG. 7 is a flowchart illustrating the operation of the sanitary washing toilet seat according to the embodiment.
This flowchart shows the operation in the water discharge state in which the hydraulic cleaning nozzle 10 discharges the cleaning water.
For example, when the user presses the buttocks cleaning button 82 or the bidet button 83, a cleaning start signal is sent to the control unit 70. The control unit 70 opens the solenoid valve 131 based on this signal. Further, the control unit 70 sets the position of the hydraulic cleaning nozzle 10 as the reference position P. As a result, fixed cleaning is being performed (step S101).

When the remaining amount of the battery 61 becomes the fourth threshold value Vt4 or less (step S102: YES) during the execution of the fixed cleaning, the control unit 70 executes the forced water stop. That is, the control unit 70 closes the solenoid valve 131 (step S103).

In addition, the sanitary washing toilet seat 100 has a notification unit 87 (see FIG. 2). The notification unit 87 notifies the user that the remaining amount of the battery 61 is equal to or less than the fourth threshold value Vt4 and the forced water stoppage has been executed. Any means such as sound notification and light notification can be used for this notification. The notification unit 87 is, for example, an LED (Light Emitting Diode), a liquid crystal display, an organic EL display, a speaker, or the like. In this example, the notification unit 87 is an LED provided in the operation unit 80, and by lighting or blinking in a predetermined pattern A, the remaining amount of the battery 61 for the user becomes the fourth threshold value Vt4 or less. Is notified (step S104). As a result, it is possible to prevent the user from misunderstanding that the water discharge has been completed as a failure.

When the remaining amount of the battery 61 is larger than the fourth threshold value Vt4 (step S102: NO) during the execution of the fixed washing, the sanitary washing toilet seat 100 performs the following operations.
When the user presses the stop button 81 (step S105: YES), the control unit 70 closes the solenoid valve 131 (step S106).

When the user presses the position adjustment button 85 (“front” button 85a or “rear” button 85b) (step S107: YES), when the remaining battery level of the battery 61 is equal to or less than the second threshold value Vt2 (step S108: YES), the control unit 70 does not execute the position adjustment mode. In this case, the control unit 70 keeps the motor 21 stopped (step S109), and the notification unit 87 tells the user that the remaining amount of the battery 61 is equal to or less than the second threshold value Vt2 according to the predetermined pattern B. Notify that (step S110). This prevents the user from misunderstanding that the position adjustment mode is not executed as a failure.

When the position adjustment button 85 is pressed and the remaining amount of the battery 61 is larger than the second threshold value Vt2 (step S108: NO), the control unit 70 starts executing the position adjustment mode (step S111). For example, the control unit 70 starts control to rotate the hydraulic cleaning nozzle 10 by −Δθ when the “rear” button 85b is pressed, and the hydraulic cleaning nozzle 10 when the “front” button 85a is pressed. The control for rotating 10 by + Δθ is started.

When the remaining amount of the battery 61 becomes the second threshold value Vt2 or less (step S108: YES) during the execution of the position adjustment mode (step S112: NO), the control unit 70 executes the position adjustment forced stop (step). S109), the notification unit 87 performs notification (step S110).
When the rotation of Δθ of the hydraulic cleaning nozzle 10 is completed (step S112: YES), the motor 21 is stopped (step S113).

When the user presses the flow rate adjustment button 86 (“large” button 86a or “small” button 86b) (step S114: YES), when the remaining amount of the battery 61 is equal to or less than the third threshold value Vt3 (step S115: YES), the control unit 70 does not execute the flow rate adjustment mode. In this case, the control unit 70 keeps the motor of the electric flow rate adjusting valve 132 stopped (step S116), and the notification unit 87 tells the user that the remaining amount of the battery 61 is the third according to the predetermined pattern C. Notify that the threshold value is Vt3 or less (step S117). This prevents the user from misunderstanding that the flow rate adjustment mode is not executed as a failure. The pattern C may be the same as the pattern B.

When the flow rate adjustment button 86 is pressed and the remaining amount of the battery 61 is larger than the third threshold value Vt3 (step S115: NO), the control unit 70 starts executing the flow rate adjustment mode (step S118). For example, the control unit 70 starts control to increase the flow rate of the washing water by a predetermined amount when the "large" button 86a is pressed, and increases the flow rate of the washing water when the "small" button 86b is pressed. Control to reduce the predetermined amount is started.

When the remaining amount of the battery 61 becomes the third threshold value Vt3 or less (step S115: YES) during the execution of the flow rate adjustment mode (step S119: NO), the control unit 70 executes the flow rate adjustment forced stop (step). S116), the notification unit 87 performs notification (step S117).
When the change of the predetermined amount of the flow rate is completed (step S119: YES), the motor of the electric flow rate adjusting valve 132 is stopped (step S120).

When the user presses the nozzle move button 84 (step S121: YES) and the remaining amount of the battery 61 is equal to or less than the first threshold value Vt1 (step S122: YES), the control unit 70 is in the move cleaning mode. Do not execute. In this case, the control unit 70 keeps the motor 21 stopped (step S123), and the notification unit 87 tells the user that the remaining amount of the battery 61 is equal to or less than the first threshold value Vt1 according to the predetermined pattern D. Notify that (step S124). This prevents the user from misunderstanding that the move cleaning is not performed as a failure.

When the nozzle move button 84 is pressed and the remaining amount of the battery 61 is larger than the first threshold value Vt1 (step S122: NO), the control unit 70 starts the move cleaning mode (step S126 or step S128). At this time, when the remaining amount of the battery 61 is larger than the fifth threshold value Vt5 (step S125: NO), the control unit 70 sets the move time as the first predetermined time (step S127). When the remaining amount of the battery 61 is the fifth threshold value Vt5 or less (step S125: YES), the control unit 70 sets the move time to the second predetermined time (step S129).

When the nozzle move button 84 is pressed again and instructed to stop the move cleaning mode before the predetermined move time elapses (step S127: NO or step S129: NO) (step S132: YES or step S133: YES). ), The control unit 70 moves the hydraulic cleaning nozzle 10 to the nozzle standard position (reference position P) (step S130). After that, the motor 21 is stopped (step S131).

When the predetermined move time elapses (step S127: YES or step S129: YES), the control unit 70 executes the move cleaning automatic stop. At this time, the control unit 70 moves the hydraulic cleaning nozzle 10 to the nozzle standard position (reference position P) (step S130). After that, the motor 21 is stopped (step S131).

The control unit 70 holds the solenoid valve 131 in the open state in order to continue discharging the cleaning water from the hydraulic cleaning nozzle 10 even after the movement of the hydraulic cleaning nozzle 10 is stopped by the automatic stop of the move cleaning. To do. That is, after the move cleaning is automatically stopped, the fixed cleaning mode is executed. By continuing the water discharge even after the automatic stop of the move cleaning in this way, it is possible to prevent the water discharge from ending in a state where the local dirt is not completely removed.

Further, as described above, when the control unit 70 automatically stops the movement of the hydraulic cleaning nozzle 10 by the automatic stop of the move cleaning, the control unit 70 places the hydraulic cleaning nozzle 10 in a preset predetermined position (for example, the reference position P). After moving to, the movement of the hydraulic cleaning nozzle 10 is stopped. By moving the hydraulic cleaning nozzle 10 to a predetermined position, it is possible to prevent the hydraulic cleaning nozzle 10 from stopping at a position where the usability is not good. As a result, water can be continuously discharged at the optimum position after the automatic stop of the move cleaning, so that it is possible to prevent the cleaning property from being deteriorated.

Further, in steps S104, S110, S117 and S124, the notification unit 87 operates for a predetermined time and then automatically stops. That is, the operation of the notification unit 87 is stopped without being based on the operation of the user in the operation unit 80 or the like. By automatically stopping the notification unit 87, the power consumption of the notification unit 87 can be suppressed. The predetermined time may be any length such that the user can notice the operation of the notification unit 87, and is, for example, about 5 seconds or more and 10 seconds or less.
