The present invention relates to a water spouting device provided with:

[0002]

2. Description of the Related Art A water discharge device of this type is installed and used in a bathroom or a pool, and a high value-added water discharge device has been proposed through diversification of water discharge forms. For example, in a shower head in a bathroom, a plurality of water discharge nozzles for realizing water discharge in different water discharge forms are movably arranged at an outlet of mixed water supplied from a hot water mixer tap, and each water discharge nozzle is switched. ing. Therefore, when each of the water discharge nozzles is appropriately selected and switched, the water discharge form includes a water discharge form determined by the hole shape of the water discharge nozzle, for example, a water discharge form (straight) that discharges in a straight shape, and a foam form including bubbles. A water discharge form (foam) that discharges water to the water or a water discharge form (water-sling) that discharges water in a rod shape with a certain head is provided.

[0003]

As a mechanism for selecting a water discharge mode, that is, a switching mechanism for driving each water discharge nozzle, a switch mechanism for a water discharge nozzle using a drive source such as a manual lever or a motor can be considered. However, the following problems have been pointed out for each of the switching mechanisms.

In a switching mechanism using a manual lever, it is necessary to operate the lever every time a change in the water discharge mode is desired, and the operability is lacking. On the other hand, when a drive source such as a motor is used in combination, operability can be improved by remotely operating the drive source. However, the drive source of the drive unit such as the water discharge nozzle built in the shower head was secured,
As a result, the following specific problems remain for the purpose of transmitting the driving force of the driving source to the driving unit.

If the drive source is a small motor and is incorporated in the shower head together with a drive unit such as a water discharge nozzle, the drive unit and the drive source can be connected directly or by using a very small transmission mechanism. For this reason, even when the user takes a shower while holding the shower head by hand, the operability is not relatively impaired. In other words, a small motor must be used as the driving source.

[0006] By the way, although water alone may be spouted from the shower head, spouting of hot water from the water heater is impossible from the viewpoint of safety. Therefore, high-temperature water and water are mixed. The mixed hot and cold water whose temperature has been adjusted is discharged.
When performing temperature adjustment in this manner, generally, a flow control valve or the like is provided in each of a pipeline from a water heater and a water supply pipeline,
This valve is driven to control the mixing ratio of hot water and water.

When the temperature of the mixed hot and cold water is changed from a shower head having a built-in water discharging nozzle and a small motor to another water discharging mode while the mixed hot and cold water is being discharged in a certain water discharging mode, the mixed hot and cold water flows into the shower head. It is necessary to switch the water discharge nozzle by driving the motor in the situation where the water exists. In such a case, since the motor is small, it is necessary to temporarily suspend the flow of the mixed hot water into the shower head in consideration of the load. Furthermore, in order to avoid misfire of the water heater due to the stoppage of the supply of hot water from the water heater, it is necessary to control at least the flow regulating valve in the pipeline from the water heater to zero flow.

At the same time as the completion of the switching of the water discharge nozzle by the motor, that is, the completion of the change of the water discharge form, it is necessary to control the return of the flow control valve and the like in the pipeline from the water heater to the original state. Therefore, it takes a long time to change the discharge form of the mixed hot and cold water in the shower head, and the responsiveness deteriorates. As a result, the user taking a shower may feel uncomfortable.

[0009] The present invention is made to solve the above problems, and an object thereof to improve the response of the drive control of the drive unit definitive in ejection water destination with a built-in driver.

A button for changing the temperature is provided, however, since it is not directly related to the gist of the present invention, the description thereof is omitted.

Next, the shower head S will be described. As shown in FIG. 4, the shower head S, which can switch between four types of water discharge modes such as squatting, has a water discharge channel 70.
A shower head main body 72 formed by securing a device storage space 71 other than the flow path, and a cap 74 formed by opening a water discharge window 73 on the side surface. It is constructed by assembling. Further, it is connected to the end of the shower hose 75 connected to the water discharge switching section 27 via a connection fitting 76.

In a space formed by the shower head main body 72 and the cap 74, a rotating shaft 78 of a motor 77 housed in the equipment housing space 71 penetrates the sealing members 79a and 79b and protrudes from the main body side. A rotary spout 80 is fixed to the rotary shaft 78. The rotating water discharge body 80 is a water discharge nozzle divided into four in the circumferential direction (in the figure, the water discharge nozzle 80
a, 80b) and rotates integrally with the rotating shaft 78. Each water discharge nozzle is provided with a water discharge inflow hole 81 on its bottom surface, and on its side surface is provided with water discharge holes (water discharge holes 82a and 82b are shown in the figure) for realizing water discharge in each of the above water discharge forms. In addition, the sealing members 79a and 79b are provided with a water discharge nozzle (see FIG.
Water discharge nozzle 80 with water discharge hole 82a facing water discharge window 73
A communication hole 83 is provided between the water discharge inflow hole 81 and the water discharge passage 70 in FIG.

Accordingly, when the shower head S is set as a water discharge destination by the water discharge switching unit 27 and a predetermined water discharge nozzle is caused to face the water discharge hole 73 by the motor 77, the hot and cold water flowing from the shower hose 75 is discharged in the figure. As shown by arrows, the water discharge passage 70 of the shower head main body 72 and the communication hole 8
3. The water reaches the water discharge nozzle through the water discharge hole 81. After passing through the water discharge hole of the predetermined water discharge nozzle, water is discharged in a water discharge form corresponding to the water discharge hole. For example, if the water discharge nozzle 80a is a water discharge nozzle provided with a water discharge hole 82a corresponding to water discharge in a straight water discharge form, and as shown in the drawing, if the water discharge hole 82a faces the water discharge window 73, from the water discharge window 73, Water is discharged in a straight water discharge form. Further, the water discharge nozzle 80b is a water discharge nozzle provided with a water discharge hole 82b corresponding to a water discharge in a sloping water discharge form. When the water discharge hole 82b faces the water discharge window 73 by rotating by 180 degrees from the position shown in the figure, a water discharge window is provided. From 73, water is spouted in the form of spouting water.

The equipment storage space 7 of the shower head main body 72
In addition to the motor 77, an electronic control unit (not shown) for controlling the driving of the motor and a water discharge nozzle that detects the rotation position of the rotation shaft 78 and exposes the water discharge hole to the water discharge window 73 are provided in 1. A water discharge mode detection sensor (not shown) for performing the operation is stored. Further, in the thick portion 72a of the main body side wall below the water discharge window 73, a water discharge form selection button 84 for changing a water discharge nozzle for causing a water discharge hole to face the water discharge window 73 and selecting a water discharge form, and a water supply from the shower head S are provided. An on-off button 85 and the like for instructing start / stop of water discharge are covered with a waterproof resin sheet 86 and are disposed so as to be freely pressed.

The electronic control unit on the side of the shower head S is connected not only to the above-mentioned sensors and buttons, but also to the electronic control unit SS in the shower tower ST in consideration of leakage. Then, a control signal is exchanged between the two electronic control units.

Specifically, the ON-side of the shower head S side
When the off button 85 is pressed to instruct the start / stop of water discharge from the shower head S, a control signal is output to the electronic control unit SS in the shower tower ST via the electronic control unit on the shower head S side. Then, the water discharge switching unit 27 is controlled by the electronic control unit SS that receives this signal, and the solenoid valve is turned on and off, and the water discharge from the shower head S is started and stopped. In addition, shower tower S
The singing designation button 57, the straight designation button 58, the foam designation button 59, the mist designation button 60, and the water discharge form selection button 8 of the shower head S of the operation panel P attached to T
When 4 is pressed to change the water discharge mode, a control signal is transmitted and received between the electronic control unit SS and the electronic control unit on the showerhead S side. That is, a signal for starting motor rotation is output from the electronic control unit SS, and a signal indicating completion of change of the water discharge mode is output to the electronic control unit SS. By transmitting and receiving such a signal, the drive of the motor 77 is controlled by the electronic control device on the shower head S side, and the water discharge nozzle rotates, and the water discharge nozzle corresponding to the selected water discharge form causes the water discharge hole to face the water discharge window 73. And stop.

Next, various controls performed by the water discharging apparatus 1 of the present embodiment having the above-described configuration will be described with reference to the drawings.

5 and 6 show a water discharge control (routine) which is a main control of the water discharge device 1.
The flowchart of FIG. 7 shows the water discharge mode selection button 84 of the shower head S and the slap designation button 57 of the operation panel P.
The water discharge mode change control (routine) when changing the water discharge mode by, for example, is shown.

FIGS. 5 and 6 show the first half and the second half of the water discharge routine. This water discharge routine is repeatedly executed on the electronic control unit SS side when the power is turned on. First, an initial process executed only when the power is turned on, that is, an internal register of the CPU is cleared. Thereafter, as shown in FIG. 5, the data of the water discharge destination map for specifying the water discharge destination and the water discharge form map for specifying the water discharge form from the shower head S are read to determine the water discharge destination and the water discharge form from the shower head S. (Step 100: Hereinafter, the step is simply described as S).

In this water discharge destination map, codes indicating execution of water discharge and non-execution of water discharge, for example, 1 and 0 are stored in the washing area
K, the bath currant BK, and the shower head S, and are written in a predetermined address of the backup RAM 44 secured as an area for determining a water discharge destination. For example, if the value 1 is written as a code corresponding to the shower head S, the shower head S is determined as a water discharge destination. Further, if 0 is written in all of the washing area KARAN AK, the bath KARAN BK, and the shower head S, it is determined that no water is discharged from any of the water discharge destinations. The writing of the code having the value 1 can be performed by pressing a button such as the bass callin instruction button 54 on the operation panel P, a water discharge designation button on the water discharge temperature setting panel of each curan portion, or an on-off button on the shower head S. Is interrupted at the time when the command is pressed. If the same button is continuously pressed twice, a code of 0 (non-water discharge execution) is written at that time for the corresponding water discharge destination. Further, in the initial process, a code of all 0 (non-water discharge) is written to each water discharge destination.

In the same manner as the above-mentioned water discharge destination map, the water discharge form map includes codes indicating the water discharge form selection and the water discharge form non-selection, for example, 1 and 0, and the four water discharge forms from the shower head S. (Straight, foam, mist) is written at a predetermined address of the backup RAM 44. For example, if the value 1 is written as a code corresponding to a song, it is determined that the water discharge mode is a song. In order for the water discharged in the water discharge form determined by this water discharge form map to be discharged from the shower head S, the code corresponding to the shower head S in the water discharge destination map is set to the value 1.
Is done when is written. The writing of the code of the value 1 into the water discharge form map can be performed by using the singing designation button 57 and the straight designation button 5 on the operation panel P.
8. When the foam designation button 59, the mist designation button 60, or the water discharge mode selection button 84 of the shower head S is pressed, an interruption process is performed. Also, in the initial processing, a code of value 1 (water discharge mode selection) is written only for a straight water discharge mode that is frequently used.

Next, the water discharge amount and the water discharge temperature preset for the water discharge destination and the water discharge form read in S100 are read from the backup RAM 44 (S110). The set water discharge amount and the set water discharge temperature are determined by a temperature change button (not shown) on the water discharge temperature setting panel 35 of each curan,
The daily operation of the water discharge temperature increase instruction button 62, the water discharge temperature decrease instruction button 63, and the like on the operation panel P, and the operation at the time of construction of the water discharge device 1 are performed in advance by the backup RA.
It is written to a predetermined address of M44. This writing is interrupted when the corresponding button is operated, and is set according to each water discharge destination and water discharge form.

Subsequent to reading of the water discharge destination, etc., the flow rate sensors 7 and 9 and the temperature sensors 11 and 1 in the hot water mixer tap UM are used.
The temperature and flow rate of the water itself and the temperature of the hot water itself in the inflow pipe 3 and the inflow pipe 5 are read from the sensors 3 and the like, and the water discharge temperature is read from the temperature sensor 25 provided in the merging flow path 23 (S120). . At this time, the merging channel 23
A control signal corresponding to the detected water discharge temperature is output to the operation panel P, and the temperature is displayed on the water discharge temperature display 53.

Next, the flow rates of water and hot water are calculated based on the set water discharge amount and the set water discharge temperature read in S110, the detection values from the respective sensors read in S120, and the like (S1).
30). Then, the flow rate adjustment amounts of the flow rate adjustment valves 15 and 17 corresponding to the calculated flow rates, that is, the drive amounts of the actuators 19 and 21 are calculated (S140). Next, a drive signal is output to each actuator to execute the water discharge at the water discharge amount and the water discharge temperature read at S110 from the water discharge destination read at S100 (S
150). In response to this signal, each actuator is driven and each flow rate adjusting valve adjusts the flow rate, so that the calculated flow rate of water and hot water flows into the merging flow path 23 and prepares for water discharge through the switching control by the water discharge switching unit 27. .

Thereafter, it is determined whether or not the water discharge destination read in S100 is the shower head S (S155).
Here, if it is determined that the water discharge destination is other than the shower head S (in the present embodiment, the washing area Karan AK or the bath Karan BK), it corresponds to the water discharging destination (either the washing area Karan AK or the bath Karan BK) read in S100. A drive signal (ON signal) is output to the solenoid valve of the water discharge switching unit 27 (S160). In response to this signal, the water discharge switching unit 27 turns on the corresponding solenoid valve, thereby controlling the water discharge destination (either the washing area Karan AK or the bath Karan BK).
Thereafter, the mixed hot water adjusted to the set water discharge amount and the set water discharge temperature in S150 is discharged. In other words, if the water spouting destination is each Karan section of the washing area Karan AK or Baskaran BK,
Since there is no obstacle in starting the water discharge, the corresponding electromagnetic valve is driven to immediately discharge water from the curran portion.

After the water is thus discharged, the flow shifts to S100, and the processing described above is repeated. Therefore, if the water discharge destination determined in S100 is each of the wash basin Karan AK or the Baskaran BK, when water discharge is started from the water discharge destination, the water discharge is performed until the code of the water discharge destination map relating to the water discharge destination becomes 0. Will be continued.

On the other hand, if it is determined in S155 that the water discharge destination is the shower head S, the process proceeds to S of the flowchart shown in FIG.
It moves to 165. In S165, there is an instruction to change the water discharge mode depending on whether or not the operation button P, the straight specification button 58, the foam specification button 59, the mist specification button 60, and the water discharge mode selection button 84 of the shower head S on the operation panel P are operated. It is determined whether or not. Here, if the buttons are not operated, it is determined that there is no need to change the form of water discharge from the shower head S, and a drive signal (ON signal) is output to the solenoid valve of the water discharge switching unit 27 corresponding to the shower head S (S170). ), And then proceeds to S100. In other words, even when the water discharge destination is the shower head S, if there is no need to change the water discharge mode, that is, change the water discharge nozzle by the rotation of the rotary water discharge body 80, there is no obstacle in starting the water discharge. By driving the valve, water is immediately discharged from the shower head S. Until the code of the water discharge destination map for the shower head S is set to 0, the water discharge from the shower head S is continued in the same water discharge mode.

However, if it is determined in S165 that the form of water discharge from the shower head S needs to be changed, first, the water discharge switching unit 27 corresponding to a water discharge destination other than the shower head S (either the washing area Karan AK or the bath curan BK). A drive signal (ON signal) is output to the electromagnetic valve (S180), and thereafter, a drive signal (OFF signal) is output to the electromagnetic valve of the water discharge switching unit 27 corresponding to the shower head S (S190). That is, when the water discharge destination is the shower head S and the water discharge mode is changed, the water discharge from the water discharge destination other than the shower head S (either the washing area Karan AK or the bath curan BK) starts, Are sequentially executed in this order.

Thereafter, it is determined whether or not the change of the water discharge form accompanying the rotation of the rotary water discharge body 80 has been completed (S19).
5). This determination is made based on whether or not a water discharge mode change completion signal has been input from the electronic control device on the shower head S side.
Here, if it is determined that the change of the water discharge mode is not completed, it is determined that the water discharge from the shower head S in the water discharge mode instructed to be changed cannot be started, and the process proceeds to S100 described above, and the processing of each of the above steps is performed. , Until the change of the water discharge form is completed. That is, until the rotation of the rotary water discharger 80 is completed, the start of water discharge from the shower head S is waited, and water is discharged from water discharge destinations other than the shower head S.

On the other hand, if it is determined in step S195 that the change of the water discharge form has been completed based on the water discharge form change completion signal, it is determined that the water discharge from the shower head S in the water discharge form instructed to be changed can be started, and the flow proceeds to the next S200. I do. This S20
At 0, a drive signal (ON signal) is output to the solenoid valve of the water discharge switching unit 27 corresponding to the shower head S. Thereafter, a drive signal (OFF signal) is output to the solenoid valve of the water discharge switching unit 27 corresponding to the water discharge destination (either the washing area Karan AK or the bath Karan BK) other than the shower head S (S210).
The process proceeds to S100. That is, after the change of the water discharge mode is completed, the start of the water discharge from the shower head S and the interruption of the water discharge from the water discharge destination other than the shower head S (either the washing basin AK or the bath basin BK) are sequentially executed in this order. I do.

Therefore, the water discharge from the shower head S in the water discharge mode instructed to change is performed at the set water discharge amount and the set water discharge temperature. Further, the water discharge from the shower head S in the water discharge mode instructed to change is continued until the code of the water discharge destination map relating to the shower head S is set to 0, or until the water discharge mode is instructed to change again. Will be.

Next, the water discharge mode changing routine will be described. This water discharge mode change routine is performed by the slap designation button 57 and the straight designation button 5 on the operation panel P.
8. Each time the foam designation button 59, the mist designation button 60, or the water discharge mode selection button 84 of the shower head S is pressed, the electronic control unit of the shower head S executes an interruption.

When the water discharge mode changing routine is executed in this manner, first, as shown in FIG. 7, this routine is based on a change instruction from each of the above buttons on the operation panel P for individually specifying the water discharge mode, or as shown in FIG. It is determined whether the change is based on a change instruction from the water discharge mode selection button 84 of the head S (S300). If it is determined that the instruction is a change instruction from the water discharge mode selection button 84, the drive amount (90 degrees × N) of the motor 77 is calculated according to the number of operations N (S31).
0), the process proceeds to S330 described later.

On the other hand, if it is determined that the instruction is a change instruction from each of the buttons on the operation panel P, it is determined whether the current water discharge form from the shower head S is the water discharge form instructed to be changed by the water discharge form detection sensor. A determination is made based on the detection signal (S315). Here, if an affirmative determination is made, this routine ends without performing any processing. However, if a negative determination is made, the amount of rotation of the rotary water discharger 80, that is, the amount of drive of the motor 77, required to change the current water discharge form determined from the water discharge form detection sensor to the change-instructed water discharge form is calculated (S320). ). For example, as shown in FIG. 4, when the current water discharge mode is straight and the water discharge nozzle 80 a has the water discharge hole 82 a facing the water discharge window 73, and the water discharge nozzle 80 a is instructed to change the water discharge nozzle 82 a, the water discharge nozzle is changed. The driving amount (180) until the water discharge hole 82b faces the water discharge window 73
Degree of rotational drive) is calculated.

When the motor drive amount is calculated in S310 and S320 in this way, a drive signal corresponding to the calculated drive amount is output to the motor 77 (S330), and the rotary water discharging body 80 is output.
To rotate.

Thereafter, it is determined whether or not the change of the water discharge form due to the rotational drive of the rotary water discharge body 80 is completed based on the detection result from the water discharge form detection sensor (S335), and the process waits until the change is completed. In the case of the change of the water discharge form described above, it is determined whether or not the rotary water discharge body 80 has rotated by 180 degrees and the water discharge nozzle 80b has reached a position where the water discharge hole 82b faces the water discharge window 73, and waits until that. . Here, if it is determined that the change to the instructed water discharge mode has been completed, a water discharge mode change completion signal is output to the electronic control unit SS (S34).
0), this routine is temporarily ended.

When the water discharge mode change completion signal is output in this manner, the electronic control unit SS that has received the signal determines that the change of the water discharge mode has been completed in S195 in the above water discharge routine, and as described above, S200, The process of S210 is performed. Therefore, water discharge from the shower head S in the water discharge mode instructed to change is performed at the set water discharge amount and the set water discharge temperature.

As described above, the water discharge device 1 of the present embodiment.
Means that when the mixed water is discharged from the shower head S in the water discharge form of squatting, straight, foam, or mist while the mixed hot water is being discharged from the shower head S, the water discharge form is changed. Prior to the drive control of the rotary water discharger 80, the water discharge switching unit 27 is controlled to switch the water discharge destination of the mixed hot water to a water discharge destination other than the shower head S (either the washing place Karan AK or the bath curan BK). In other words, before driving the rotary water discharger 80 for changing the water discharge form, the mixed hot water discharged from the shower head S up to that point is discharged from either the washing area Karan AK or the bath curan BK.

When the drive control of the rotary water discharge body 80 for changing the water discharge form is completed, the water discharge switching section 27 is controlled to switch the water discharge destination of the mixed hot water to the shower head S.
Thus, the mixed hot and cold water is discharged from the shower head S in the changed water discharge mode.

[0057] Accordingly, while driving the rotating spouting member 80, mixing hot water spouting from the shower head S is interrupted, and the other ejection water destination or we mixed hot water spouting is carried out. As a result, according to the water discharger 1 of the present embodiment, the rotary water discharger 80 can be driven under a low load state in which the mixed hot water does not flow, and the flow control valve 15 and the flow control valve 17 can be fully closed. Since it is not necessary to control the return to the original state, it is possible to change the discharge form of the mixed hot water from the shower head S in a short time. In addition, it is possible to reduce the size of the shower head S and improve the usability thereof by reducing the size of the motor 77 that is the driving source of the rotary water discharger 80.

In order to change the form of water discharge, a rotary water discharge body 8 is provided.
Since the start of water discharge from the water discharge destinations other than the shower head S and the interruption of the water discharge from the shower head S were sequentially executed in this order at the time of switching the water discharge destination before driving the water heater 0, The flow control valve 17 in the hot water inflow pipe 5 does not perform flow control (zero flow) for a sudden change in the control amount. Therefore, safety can be improved without fear of misfire of the water heater.

Although one embodiment of the present invention has been described above, the present invention is not limited to such an embodiment, and may be implemented in various modes without departing from the gist of the present invention. Of course.

For example, in the above embodiment, the water discharge destination to be switched to before the driving of the rotary water discharger 80 for changing the water discharge form is either the washing place Karan AK or the Baskaran BK. However, the following configuration is adopted. You can also. That is, a so-called soot water pipe directly connected to a drain pipe for discharging drain water in the bathroom to the outside is connected to the water discharge switching section 2.
7 and set the water discharge destination to be switched to the washing area Karan A.
Instead of K or Baskalan BK, this water pipe can be used.

When returning the mixed water discharge destination to the shower head S, the completion of the drive control of the rotary water discharger 80 is carried out, that is, the completion of the drive is confirmed. It is also possible to adopt a configuration in which the above-described return operation is performed at a point in time when a predetermined time has elapsed since the destination of the water discharge is switched to a location other than the shower head S.

[0062]

As described in detail above water discharger of the present invention, the midst of spouting whether we mixed hot water driver built ejection water destination certain water discharge form, when changing the water discharge of another water discharge form , the over while the drive unit is driven and controlled for water discharge form changing, the mixed hot water of the water discharge destination to the drive unit built ejection water destination than <br/> out of the water discharge destination.

[0063] Thus, while drives controlling the drive unit, mixed hot water of the water discharge of the drive unit built ejection water destination or colleagues is interrupted, and the other ejection water destination or we mixed hot water of the water discharge is performed. As a result, according to the water discharge device of the present invention, the drive unit that is driven in the path of the inflowing fluid can be driven in a low-load state in which no fluid flows in, and also controls any control associated with the adjustment of the temperature of the mixed hot and cold water. it does not require the front and rear of the drive control parts, the change of the mixed hot water of the water discharge form the driver built-discharge water destination or we can be performed in a short time.
