DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in FIG. 1, the conventional hot water flush toilet seat includes a toilet seat 7 and a telescopic nozzle 9 for ejecting flush water to a local part of the user, a cleaning function for supplying hot water to the nozzle 9 and a local part of the user. Functional unit 8 with a drying function to blow out hot air
And a sleeve portion 12 disposed beside the functional portion 8, and an operation switch 13 for turning on / off a washing function and a drying function in a state where a user is seated on the toilet seat 7 is disposed on the sleeve portion 12. An operation unit 6 is provided.

As shown in FIG. 1, the operation unit 6 includes a toilet seat 7
In order to make it easy for a user who sits on the toilet seat 7 to operate, it is generally arranged at the front upper part of the sleeve 12 arranged beside the toilet seat 7, but a type of hot water washing without the sleeve 12 is provided. The toilet seat may be provided on a side surface of the functional unit 8 or on a wireless remote controller for operating the hot water washing toilet seat by a wireless signal such as infrared rays (not shown).

Hereinafter, the same is true regardless of the form in which the operation unit 6 is arranged.

In such a conventional type of hot water flush toilet seat, when the user's local area is washed or dried, the user 5 sitting on the toilet seat 7 needs to touch the operation switch 13 with his / her finger and press it. However, as long as the user operates the operation switch 13 provided in the location toilet, the operation switch 13 is not hygienic for the user.

Embodiments of the present invention for solving these problems are shown in FIGS.

In FIGS. 2 and 3, the operation unit 6 is provided with the distance detecting means 2 instead of the operation switch 13 (FIG. 1) toward the upper surface of the operation unit 6. Instead of pushing the operation switch 13 (FIG. 1), the user
The warm water flush toilet seat is operated (non-contact operation) by holding the hand 5 over the upper part of the device, which can be said to be more sanitary than the operation by the switch 13. In the telescopic nozzle 9, moving forward means that the nozzle extends in the longitudinal direction of the nozzle itself by the drive motor, and the nozzle becomes longer. Moving backward and forward and vice versa. Here, the user first sits on the toilet seat. And after performing the stool,
Perform buttocks washing. In the standard state, the washing is set to the posterior washing, the adjustment after the start of the washing is set to water pressure adjustment (setting of water force), and the adjustment at the time of drying is set to temperature adjustment. When the user holds the hand 5 over the distance detecting means 2 and the distance L is smaller than a predetermined distance (La is, for example, 30 mm), the operation shifts from the stopped state to the cleaning start operation. As will be described in detail later with reference to FIG. 5, buttocks washing (nozzle position standard) is started. Next, when trying to adjust the water force, the water force is adjusted by raising and lowering the position of the hand 5 as described above. If the user wants to perform massage cleaning, the user can perform massage cleaning in which the water force is periodically changed by periodically raising and lowering the hand 5. Next, when it is desired to adjust the position of the nozzle during the washing, the nozzle / water pressure switch 15 is pushed and the position of the hand 5 is moved up and down in the same manner as in the switch to adjust the nozzle position.
(Detailed description with reference to FIG. 6) If the user wishes to perform move cleaning, the user can perform move cleaning in which the nozzle position is periodically changed back and forth by periodically moving the hand 5 up and down. Although the above description has been made with respect to the posterior cleaning, the bidet cleaning is switched to the bidet by the posterior / bidet switch 18, and when the distance L is smaller than a predetermined distance (La is, for example, 30 mm), the bidet cleaning is stopped. Move to the start operation. After that, the above operation may be performed. In the above-described cleaning operation, when an operation is received, a beeping sound is generated to notify the user or the L of the operation unit is notified.
The ED display unit 14 displays the nozzle position and the water force so that the user can confirm it.

Next, if the washing is completed, and if it is desired to dry, if the washing is completed during the continuation of sitting, then the user holds the hand 5 over the distance detecting means 2 and the distance L becomes a predetermined distance (L
When a is smaller than 30 mm, for example, the operation shifts from the stopped state to the drying operation. In this case, the apparatus stores the completion of the cleaning and determines the drying operation based on the stored information. If it is desired to perform the cleaning again, the user presses the cleaning / drying switch 17 to switch to the cleaning.
Is detected when the distance is smaller than a predetermined distance (La is, for example, 30 mm). When the drying operation starts (described in detail in FIG. 10), the user can adjust the drying temperature by periodically raising and lowering the hand 5. Similarly, when an operation is received, a beep is generated to notify the user,
The level of the drying temperature is displayed on the LED display section 14 of the operation section so that the user can confirm it.

FIG. 4 is a sectional view of one embodiment of the distance detecting means 2. Hereinafter, a method for detecting the distance to the user's hand 5 will be described with reference to FIG.

In FIG. 4, the light emitted from the light projecting element 1 reaches the hand 5 held by the user, is reflected and reaches the distance detecting element 3 through the light receiving lens 4. Distance detection element 3
Is a semiconductor element generally called PSD, and the light reflected by the object to be measured (user's hand 5) passes through the light receiving lens 4 and is connected to the center point of the light receiving lens 4 by a line parallel to the light projecting axis. thus corresponding to the position of P ₁ shifted from the reference point P of the above. To detect the difference l ₂ between the P and P _1. When l ₂ is known, the distance l ₁ between the light receiving lens 4 and the distance detecting element (PSD) 3, the distance L ₂ between the light projecting element 1 and the light receiving lens 4,
That the length L ₂ to a reference point P of the light projecting device 1 and the distance sensing device 3 is _{predetermined, L 1: L 2 = l} 1: relation l ₂ holds is, L ₁ = (l ₁ × L ₁ can be calculated from L ₂ ) / l ₂ .

The above-described optical distance detecting means (generally called a distance measuring sensor) is merely an example, and emits a sound wave toward the hand 5 held by the user and reflects the sound wave on the hand 5. may be ultrasonic means to detect the distance L ₁ to the hand 5 which is held over the user by measuring the time until the come back up location emitted, means for detecting the distance any The system may be used.

[0028] In FIG. 5, with respect to the distance L ₁ was detected, indicating the application of the method of controlling the cleaning start and water force adjustment. 5 Oite, the distance L ₁ is operated continuation of current in the case further than given the distance Ld. (Washing operation is continued during cleaning, and stoppage is continued during stoppage.) In other words, it is considered that there is no user setting change request. In the standard state, the washing is set to the backside washing, the adjustment after the start of washing is set to the water pressure adjustment (setting of the water force), and the adjustment at the time of the drying is set to the temperature adjustment. It shifts from the stop state to the buttocks washing start operation. Thereafter, the nozzle extends and the nozzle starts cleaning at the standard position. Next, when the user wants to change the water force to a strong one, the user again puts his hand over the distance L.
_{When 1} becomes equal to or less than Lb and equal to or more than La, the water force is increased at a constant speed. Then, when the strength of the water force is appropriate for the user, when the hand is released (the detection of the distance to the object is stopped), the nozzle becomes farther than the detection distance Ld, the nozzle stops, and water is discharged at the current strength of the water force. continue. Similarly, if you want to change the water force to the weak, the distance L ₁ is Ld by holding the hand again
Hereinafter, when it becomes equal to or higher than Lc, the water force is weakened at a constant speed. Then, when the strength of the water force becomes appropriate for the user, when the hand is released, the distance becomes longer than the detection distance Ld, the nozzle stops, and the water continues to be discharged at the current strength of the water force. Finally when subjected to cleaning stop again, the distance L ₁ is when below La, stops been switched to the stop operation from the cleaning operation. The move as the distance L ₁ is shorter nozzle position slowly forward, although the application example strong water force, may be gradually increased wash water temperature.

[0029] Then with respect to the distance L ₁ was detected using 6 shows an application of the nozzle position control. 6, the distance L ₁ is operated continuation of current in the case further than given the distance Ld. (Washing operation is continued during cleaning, and stoppage is continued during stoppage.) In other words, it is considered that there is no user setting change request. If the posterior washing is first performed during the stop, the distance becomes equal to or less than the distance Lc, and the process shifts from the stopped state to the washing start operation. Thereafter, the nozzle extends and the nozzle starts cleaning at the standard position. Next, if the user wants to change the posterior washing position to the front, the user again puts his hand over the distance L _1.
Is less than or equal to Lb and greater than or equal to La, the nozzle starts moving forward at a constant speed. When the user arrives at a position appropriate for the user, when the user removes his hand, the distance becomes longer than the detection distance Ld, the nozzle stops, and the water continues to be discharged at the current position. Similarly, if it is desired to change the distance backward, the hand is held again and the distance L
_{When 1} becomes equal to or smaller than Ld and equal to or larger than Lc, the nozzle starts moving backward at a constant speed. When the user arrives at a position appropriate for the user, when the user removes his hand, the distance becomes longer than the detection distance Ld, the nozzle stops, and the water continues to be discharged at the current position. Finally when subjected to cleaning stop again, the distance L ₁ is when below La, stops been switched to the stop operation from the cleaning operation.

FIGS. 7 and 8 show further different applications. In Figure 7, the output L ₁ of the distance detection means 2 is less than a predetermined distance La, first nozzle starts extension out water discharge to the water discharge position. When the cleaning operation is received (the predetermined distance L
The timer t is started in a). Until the timer t is the predetermined time t ₁ has elapsed according to the distance L _1, and protraction housed around the nozzle position, after which the water discharge at the nozzle position in response to the distance L ₁ at the time when the predetermined time t ₁ has elapsed to continue. Here, the distance directly corresponds to the front-back position of the nozzle. After the predetermined time t ₁ has elapsed, the washing water is relatively increased or decreased (water force the intensity) according to the distance L _1. In order to stop the vehicle, the vehicle is stopped at a predetermined distance La or less.

In this application, not only the cleanliness due to non-contact can be improved, but also two parameters, ie, nozzle position and water strength adjustment, can be adjusted by the output of one distance detecting means, thereby improving operability. In addition, there is no need to provide a plurality of distance detecting means 2 according to the number of functions. Of course, the switching of the object to be adjusted is performed by the switch. However, the switching may be performed if the hand-paying cycle is within a predetermined value.

FIG. 8 shows another application example of FIG. Figure becomes the output L ₁ of 8 in distance detection means 2 is less than a predetermined distance La, rather than using the elapsed time t from the time of accepting washing operation (below a predetermined distance La), variations in distance L ₁ is When the time no longer varies only within a predetermined range (time 8 in which the nozzle position is no longer front and rear) are continuous predetermined time t ₂ or more, it is determined that no longer the need for adjusting the nozzle position, the nozzle position fixed at current position, it switches to a mode to increase or decrease depending flush volume of (water force) at a distance L _1. Thus, the same effect as in FIG. 7 can be obtained.

As a specific example of the blowing means, a DC brushless fan motor or an AC fan motor is used, and as a heating means, a nichrome wire electric heater or the like is generally used.

FIG. 11 is a time chart for adjusting the drying temperature and the air volume in the drying operation. In Figure 11, the output L ₁ of the distance detection means 2 is less than a predetermined distance La, heating device
(Heater) and blowing means (blowing fan) are turned on. The output of the heating means and the output of the blowing means gradually increase, and as the detection distance L1 increases, the output of the heating means and the output of the blowing means gradually decrease. Means (both means and blowing means) are turned off.
In this embodiment, the outputs of the temperature raising means and the air blowing means are switched synchronously, but need not always be synchronized. Further, the distance Lc for starting the drying operation and the distance Lc for ending the drying operation need not be the same value, and may have a hysteresis. Further, as the detection distance L1 becomes shorter, the output of the warm air means or the output of the air blowing means may become smaller. In order to stop the drying operation, the drying operation is stopped at a predetermined distance La or less.

FIG. 12 is an operation block diagram in conjunction with the seating detection means, and FIG. 13 is a timing chart thereof. There is no problem with the warm water flush toilet seat operated by the user 5 pressing the switch 13, but as shown in FIG. 4, the distance detecting means 2 uses the principle of optical triangulation using infrared rays (described above). In general, the distance detecting means uses infrared rays, so that the distance detecting means is always affected by an incandescent lamp or a fluorescent lamp installed in the toilet. The light emitted by incandescent and fluorescent lights
This is because it generally contains the same wavelength component as the light (infrared rays are generally used) that is projected by the distance detecting means 2 itself.

In the present invention, the operation surface operated by the user is generally forced to face the ceiling or the like in consideration of the operability. Generally, the operation surface of an incandescent lamp or a fluorescent lamp disposed on the ceiling of a toilet is required. The emitted light is directly applied to the distance detecting element (PSD) 3 through the light receiving lens 4 of the distance detecting means 2. In this case, the light emitted from the original light emitting element 1 and reflected on the user's hand 5 is buried in the light of the incandescent lamp or the fluorescent lamp, and the position of P1 (FIG. 4) cannot be accurately detected. . That is, l ₂ (FIG. 4) cannot be accurately detected, and it is impossible to accurately calculate the distance L ₁ to the hand 5 held by the user. As a result, it is highly likely that the hot water washing function or drying function does not operate or malfunctions.

According to the present invention, the output of the distance detecting means is disabled except when the user is seated by the sitting detecting means to prevent the hot water washing function and the drying function from operating or malfunctioning. It is. According to FIG. 12, the output of the distance detecting means 2 is transmitted to the hot water washing means or the drying means only when the output of the seating detecting means is ON (seated), and the output of the seating detecting means is OFF (non-seated). In this case, the output of the distance detecting means 2 is not transmitted to the hot water washing means or the drying means.

FIG. 13 is a timing chart of the interlocking operation of the seating detecting means, the distance detecting means and the washing operation. User 5
When the distance L ₁ is equal to or less than La to, when the seating detection means is detecting the seating, the cleaning means performs the discharge of the washing water, seated in the case of OFF detection distance L ₁ is less than or equal to La No cleaning is performed, if any.

FIG. 14 is a block diagram showing the construction of the hot water washing means. The hot water washing means includes a nozzle position adjusting means, a water force adjusting means, and a water temperature adjusting means. Here, it is shown that nozzle position adjustment, water force adjustment, and water temperature adjustment can be performed by the distance detection unit.

FIG. 15 is a block diagram showing the internal configuration of the microcomputer peripheral circuit 90 built in the sanitary washing device and its peripheral devices. The microcomputer peripheral circuit 90 includes a CPU 91 for executing various arithmetic processing for controlling the temperature of the washing water and the like according to a preset control program;
And a ROM 92 in which a control program and control data necessary for executing various arithmetic processes are stored in advance.
A RAM 93 for temporarily reading and writing various data necessary for executing various arithmetic processing in the PU 91, a backup RAM 94 for storing data even in a non-energized state,
An input processing circuit 95 for inputting signals from various sensors and switches attached to the sanitary washing device and converting the signals into signals that can be processed by the CPU 91; And the like, and an output processing circuit 96 for outputting a signal. The backup memory 94 is a non-volatile device that can be backed up by a built-in battery or is an electrically writable and readable non-volatile device such as a flash memory. Hot water tank 2
6 includes a hot water thermistor 51 and a float switch 6
2 are provided. These various sensors and switches are electrically connected to the input processing circuit 95 of the microcomputer peripheral circuit 90, and various actuators (water stop electromagnetic valves 71, Hot water heater 76, flow regulating motor 73,
A process of adjusting the nozzle position by the nozzle drive motor 74),
The cleaning process is performed. Microcomputer peripheral circuit 90
The general operation of the sanitary washing device based on the processing executed by the CPU 91 is as follows. When the user sits on the toilet seat, a signal to that effect is output from the seating sensor 61. Thereafter, the user holds the hand over the distance detection sensor 2 to shorten the detection distance (detection distance La or less), and the posterior washing is performed. When started, the nozzle drive motor 74 is driven to extend the nozzle 28 integrally to the cleaning position, and the water stop solenoid valve 7
1 is opened and the flow control switching valve 72 communicates with the buttocks washing flow path to start jetting of washing water from the nozzle head of the nozzle 28. Here, as described with reference to FIGS. 5 and 6, when the detection distance is changed, C is output from the distance detection sensor 2 through the input / output processing circuit 95.
The PU 91 calculates and drives the flow control motor 73 and the nozzle drive motor 74. Then, after the washing is completed, when the user again puts his hand to shorten the detection distance (detection distance L
a), the water shutoff electromagnetic valve 71 is closed, the flow control switching valve 72 communicates with the neutral position to terminate the ejection of the wash water, and then the nozzle drive motor 74 is reversed to retract the nozzle 28 to the storage position. . Similarly, when the user pushes the posterior / bidet switch SW18 and puts a hand on the posterior to shorten the detection distance (not more than the detection distance La), the nozzle 28 advances to the bidet cleaning position and the flow control switching valve. The cleaning water is started to be jetted from the nozzle head by communicating with the bidet cleaning flow path at 72, and the cleaning is terminated by pressing the stop SW84. Next, the drying operation will be described. After washing is completed in a state where the detection of the human body by the seating sensor 61 is continued, it can be predicted that the user will perform a drying operation next. Therefore, the completion of the cleaning is stored in the RAM 93 or the backup memory 94, and the CPU 91 determines that the cleaning is stored. , Start the drying operation. Then, as described with reference to FIG. 10, the drying motor 75 and the drying heater 78 can be controlled to adjust the drying temperature and air volume as desired by the user. Each time the CPU 91 switches each load operation due to a change in each operation and various sensors, the setting status is stored in the RAM 93 or the backup memory 94. Thus, when the operation is stopped due to an unexpected power failure or the like, the operation before the power failure can be restarted.

[0043]

As described above, according to the present invention, not only the user can start or stop the hot water jetting without touching the operation unit, but also adjust the hot water jetting amount as necessary. The nozzle position can be adjusted back and forth, the temperature of hot water can be adjusted, and the temperature and speed of hot air for drying the local area of the user can be adjusted, which is hygienic. Stable operation becomes possible.
