Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water spouting device for spouting mixed hot and cold water whose temperature is adjusted by mixing hot water and feed water from a spout, and more particularly to a drive unit for driving in a flow path of an inflowing fluid. The present invention relates to a water discharge device having a built-in drive unit water discharge port.

[0002]

2. Description of the Related Art This type of water discharge device is used by being installed in a bathroom, pool or the like, and a high value-added device has been proposed by diversifying the water discharge form. For example, in a shower head in a bathroom, a plurality of water discharge nozzles that realize water discharge in different water discharge forms are arranged at the outlet of the mixed hot water flowing from the hot water mixer, and the water discharge nozzles are configured to be 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 in the water discharge nozzle, for example, a straight water discharge form (straight), and a foam form including bubbles. The water is discharged into the water (foam) and the water is discharged into a rod shape with a certain degree of drop (standing).

[0003]

As a mechanism for selecting a water discharge form, that is, a switching mechanism for driving each water discharge nozzle, a water discharge nozzle switching mechanism using a drive source such as a manual lever or a motor is conceivable. However, the following problems have been pointed out for the respective switching mechanisms.

In a switching mechanism that also uses a manual lever, it is necessary to operate the lever every time it is desired to change the water discharge form, and the operability is poor. On the other hand, in the case where a drive source such as a motor is also used, the operability can be improved by remotely operating this drive source. However, securing a drive source for the drive unit such as the water discharge nozzle built into the shower head,
In addition, due to the fact that the driving force of the driving source is transmitted to the driving unit, the following peculiar problems remain.

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

By the way, although water alone may be discharged from the shower head, it is impossible for the hot water to be discharged from the water heater for the sake of safety. The mixed hot and cold water whose temperature has been adjusted is discharged.
When the temperature is adjusted in this way, generally, a flow rate adjusting valve or the like is provided in each of the pipeline from the water heater and the water supply pipeline,
This valve is driven to control the mixing ratio of hot water and water.

[0007] When changing the temperature-controlled mixed hot and cold water from one shower head having a water discharge nozzle and a small motor to another water discharge mode while discharging the water in a certain water discharge mode, the mixed hot and cold water is mixed in the shower head. It is necessary to drive the motor to switch the water discharge nozzle under the condition existing in. In such a case, since the motor is small, it is necessary to temporarily stop the flow of the mixed hot water into the shower head in consideration of its load. Further, in order to avoid misfire of the hot water supply device due to the stop of hot water supply from the hot water supply device, it is necessary to control at least the flow rate adjusting valve and the like in the pipeline from the hot water supply device to zero.

Then, at the same time when the switching of the water discharge nozzle by the motor is completed, that is, the change of the water discharge form is completed, it is necessary to control the return of the flow rate adjusting valve in the pipe from the water heater to the original state. Therefore, it takes a long time to change the discharge form of the mixed hot water in the shower head, and the responsiveness deteriorates. As a result, the user taking a shower is uncomfortable.

The present invention has been made to solve the above problems, and an object of the present invention is to improve the responsiveness of drive control of a drive unit at a water outlet that incorporates the drive unit.

[0010]

In order to achieve the above object, the first means adopted by the present invention is a plurality of means including a driving part built-in water discharge port having a built-in driving part for driving in an inflowing fluid path. Is a water spouting device that spouts mixed hot and cold water having a water spouting port, the temperature of which is adjusted by mixing hot water and supply water, from one of the plurality of water spouting ports, and mixing the adjusted temperatures. Water discharge destination switching means for switching the inflow destination of hot water to one water discharge outlet of the plurality of water discharge outlets, drive portion control means for driving and controlling the drive portion of the drive portion built-in water discharge outlet, and the drive portion built-in discharge outlet When the drive unit control means drives and controls the drive unit while the mixed hot water flows into the water port, the inflow destination of the mixed hot water is controlled during the drive control of the drive unit. Through the control of the water discharge destination switching means. As its gist in that it comprises a water discharge destination changing means for changing the parts built spout other spout.

[0011]

In the water discharger having the above structure, when the drive unit control means drives and controls the drive unit while the mixed hot and cold water is flowing into the drive unit built-in water discharge port, the drive unit is driven and controlled by the water discharge destination changing unit. During this time, the inflow destination of the mixed hot water is changed to a water outlet other than the water outlet of the drive unit. At this time, the inflow destination of the mixed hot water is changed through the control of the water discharge destination switching means.

That is, while the drive control of the drive unit is being executed by the drive unit control means, the discharge of the mixed hot water from the drive unit built-in spout is interrupted and the water is mixed from the spout other than the drive unit built-in spout. Hot water is discharged. As a result, the drive unit can be driven by the drive unit control means in a low load state in which the mixed hot water does not flow, and any control accompanying the adjustment of the mixed hot water temperature is performed before and after the drive control of the drive unit. Does not need in.

The water and hot water pipes of the hot and cold water mixing tap UM are provided with flow rate adjusting valves 15 and 17 for adjusting the flow rates of water and hot water in the respective pipes.
Actuators 19 and 21 that control the flow rate are attached to the valve 7. Downstreams of the flow rate adjusting valves 15 and 17 are connected to each other to form a merging flow passage 23, and water and hot water in the respective pipes join and mix there. The hot water temperature in the confluent flow path 23 is determined by the respective temperatures of water and hot water and the mixing ratio thereof. Confluence channel 23
Is provided with a temperature sensor 25 that detects the temperature of the mixed hot water in the flow path.

A water discharge switching unit 27 is provided downstream of the confluent flow path 23.
A shower head S and a bascaran BK are provided here.
And Karan AK etc. are connected to the washing area. The water discharge switching unit 27 switches the water discharge destination of the mixed water, and changes the water discharge destination by turning on / off an electromagnetic valve (not shown) provided for each water discharge port by the electronic control unit SS. Each solenoid valve is turned on and off by the electronic control unit SS depending on the usage state of the shower head S and the washing place KARAN AK.

When the actuators 19 and 21 are driven by the electronic control unit SS, water and hot water having a flow rate determined by the driving amount of each actuator flow into the merging passage 23 and are mixed. Therefore, from the shower head S or each of the currants set as the water discharge destination by the water discharge switching unit 27, the temperature of the water and the hot water itself and the temperature determined by the flow rate ratio of the water and the hot water regulated by the flow rate adjusting valves 15 and 17 are set. Mixed hot and cold water is discharged. In addition, since the water heater is a so-called No. 16 equivalent (hot water supply capacity of 25 liters or more of hot water 16 liters / min), the temperature Th on the hot water side is the water temperature Tw and the flow rate Qh on the hot water side.
With, Th = Tw + 400 / Qh. The minimum operating flow rate of this water heater is 7 liters / minute, and the maximum flow rate is 30 liters / minute when the hot water outlet is open.

Further, a water discharge temperature increase instruction button 62, a water discharge temperature decrease instruction button 63, a water discharge amount increase instruction button 64, and a water discharge amount reduction instruction button 65 are provided on the left and right sides thereof. Then, when these buttons are pressed, the signals are input to the electronic control unit SS, and the electronic control unit SS receiving the signals sets the water discharge temperature and the water discharge amount as follows.

First, when the button to be set, for example, the singing designation button 57 is pressed following the setting button 61, the water discharge temperature or the water discharge amount relating to the water discharge form of the waterfall can be set. After that, when the water discharge temperature increase instruction button 62 or the like is operated, the water discharge temperature and the water discharge amount are changed according to the number of times of the operation. Next, when the setting button 61 is pressed again, the water discharge temperature and the water discharge amount after the change are written in a predetermined address of the backup RAM 44. Such setting of the water discharge temperature and the water discharge amount is performed not only for each water discharge destination but also for each water discharge form. It should be noted that, as shown in the drawing, in addition to the character string, a picture in which the corresponding function is designed is written on the surface of each button.

Further, when the push-type Bascaran instruction button 54 or the like for individually designating the spouting destination or the casting designation button 57 or the like for designating the spouting form is pushed, the signal is sent to the electronic control unit SS. The water discharge destination and the water discharge form are switched by the electronic control device SS that has received the input and received it. For example, if the bath currant instruction button 54 is pressed, water is discharged from the currant portion 33 of the bath currant BK, and similarly, when the washing place currant instruction button 55 or the shower head designating button 56 is pushed, the washing place currant AK or the shower head S is discharged. It is spouted. Moreover, if the designation button for designating a different spouting destination is pressed while water is being spouted from a certain spouting destination, the spouting from the certain spouting destination that has been sprinkling until then is interrupted, and the pushed designation button is pressed. The water is spouted from the corresponding spouting destination. Similarly, with respect to each designation button or the like for designating the water spouting form, the shower head S having the spouting form corresponding to the pressed designating button

The spout water temperature setting panels 35 and 37 of the washing place Karan AK and the bath currant BK change water spouting buttons for switching spouting water among water, temperature-adjusted hot water and hot water, and hot water temperature at the time of hot water sprinkling. Although a temperature changing button is provided for this purpose, the description thereof is omitted because it is not directly related to the gist of the present invention.

Next, the shower head S will be described. As shown in FIG. 4, the shower head S capable of switching four types of water discharge forms such as pouring is shown in FIG.
And a shower head main body 72 formed by ensuring a device storage space 71 other than this flow path, and a cap 74 formed by opening a water discharge window 73 on the side surface. The shower head main body 72 is watertightly closed with the cap 74. It is assembled and assembled. Further, it is connected to the end of the shower hose 75 connected to the water discharge switching unit 27 via a connecting fitting 76.

In the space formed by the shower head main body 72 and the cap 74, the rotary shaft 78 of the motor 77 housed in the equipment housing space 71 penetrates the seal members 79a and 79b and projects from the main body side. A rotary water discharge body 80 is fixed to the rotary shaft 78. The rotary water discharger 80 has a water discharge nozzle divided into four in the circumferential direction (in the figure, the water discharge nozzle 80
a and 80b are shown), 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 is provided with a water discharge hole (shown in the figure as water discharge holes 82a and 82b) for realizing water discharge in each of the above-described water discharge modes on its side surface. In addition, the sealing materials 79a and 79b are water discharge nozzles (in the drawing, the water discharge holes 73 facing the water discharge holes).
Water discharge nozzle 80 with water discharge hole 73 facing water discharge window 73
A communication hole 83 is provided between the water discharge inflow hole 81 and the water discharge flow passage 70 of a) and connects them.

Therefore, when the shower head S is set as the water discharge destination by the water discharge switching unit 27 and the predetermined water discharge nozzle makes the water discharge hole face the water discharge window 73 by the motor 77, the hot and cold water flowing from the shower hose 75 is As shown by the arrow, the water discharge passage 70 of the shower head main body 72, the communication hole 8
3. It passes through the water discharge inflow hole 81 and reaches the water discharge nozzle. Then, 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, the water spouting nozzle 80a is a water spouting nozzle having a water spouting hole 82a corresponding to water spouting in a straight water spouting form, and as shown in the figure, if the water spouting hole 82a faces the water spouting window 73, from the water spouting 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 the water discharge in the form of water discharge, and if the water discharge hole 82b faces the water discharge window 73 by rotating 180 degrees from the position shown in the figure, the water discharge window is formed. From 73, water is discharged in the form of water discharge.

Equipment storage space 7 of the shower head main body 72
In FIG. 1, in addition to the motor 77, an electronic control device (not shown) for driving and controlling the motor, and a water discharge nozzle that detects the rotation position of the rotary shaft 78 and faces the water discharge window 73 with the water discharge hole are determined. A water discharge form detection sensor (not shown) for doing so is housed. In addition, in the thick portion 72a of the main body side wall below the water discharge window 73, a water discharge mode selection button 84 for changing the water discharge nozzle that makes the water discharge hole face the water discharge window 73 and selecting a water discharge mode, and a shower head S are used. An on-off button 85 for instructing the start / stop of water discharge is covered by a waterproof resin sheet 86 and is arranged so as to be pressed freely.

The electronic control unit on the shower head S side 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 electric leakage. Then, a control signal is exchanged between both electronic control devices.

Specifically, the shower head S side is on-
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 device SS in the shower tower ST via the electronic control device on the shower head S side. Then, the electronic control unit SS that receives this signal controls the water discharge switching unit 27 to turn on / off the electromagnetic valve, and the water discharge from the shower head S is started or stopped. Also, the shower tower S
T operation button P attached to the operation panel P attached to T, straight specification button 58, foam specification button 59, mist specification button 60, and spouting form selection button 8 of the shower head S
When 4 is pressed to instruct to change the water discharge mode, a control signal is exchanged between the electronic control device SS and the electronic control device on the showerhead S side. That is, a signal for starting rotation of the motor is output from the electronic control device SS, and a signal for completing the change of the water discharge form is output to the electronic control device SS. By transmitting and receiving such a signal, the drive control of the motor 77 is performed by the electronic control device on the shower head S side, the water discharge nozzle rotates, and the water discharge nozzle corresponding to the selected water discharge mode causes the water discharge hole to face the water discharge window 73. Stop.

Next, various controls performed by the water discharger 1 of the present embodiment having the above-mentioned structure will be described with reference to the drawings.

The flow charts of FIGS. 5 and 6 show the water discharge control (routine) which is the main control of the water discharger 1.
In the flowchart of FIG. 7, the spouting form selection button 84 of the shower head S and the pouring designation button 57 of the operation panel P are shown.
The water discharge form change control (routine) at the time of changing the water discharge form by the above is shown.

The flow charts of 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 after the power is turned on. First, the initial processing that is executed only when the power is turned on, that is, the internal register of the CPU is cleared. Then, as shown in FIG. 5, the data of the water discharge destination map that specifies the water discharge destination and the water discharge form map that specifies the water discharge form from the shower head S is read to determine the water discharge destination and the water discharge form from the shower head S. (Step 100: Hereinafter, the step will be simply referred to as S).

In this water discharge destination map, the codes that mean water discharge execution and water discharge non-execution, for example, 1 and 0
K, Bascaran BK, and shower head S, which are written in a predetermined address of the backup RAM 44 secured as an area for determining the water discharge destination. For example, if the value 1 is written as the code corresponding to the shower head S, the shower head S is determined as the water discharge destination. If 0 is written in all of the washing place Karan AK, bath Karan BK, and shower head S, it is determined that no water is discharged from any water discharge destination. Note that the writing of the code of this value 1 is performed by pressing a button such as the bath currant instruction button 54 on the operation panel P, a spouting water designation button on the spouting water temperature setting panel of each curran portion, or an on / off button on the shower head S. Etc. are interrupted when they are pressed. If the same button is continuously pressed twice, a code of 0 (no water spouting) is written at that time for the corresponding spouting destination. Further, in the initial processing, all 0 (no water discharge execution) code is written to each water discharge destination.

Further, in the water discharge form map, similarly to the water discharge destination map, the codes indicating the water discharge form selection and the water discharge form non-selection, for example, 1 and 0, are assigned to the four water discharge forms from the shower head S. It is written in a predetermined address of the backup RAM 44 in correspondence with straight, foam, mist). For example, if the value 1 is written as the code corresponding to the message, it is determined that the water discharge form is messaged. In addition, in order to discharge the water in the water discharge form determined by the water discharge form map 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 being written. In addition, the writing of the code of the value 1 to the water discharge form map is performed by the operation 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. In addition, the code of the value 1 (water discharge mode selection) is written only to the straight which is the water discharge mode that is frequently used in the initial process.

Next, the water discharge amount and the water discharge temperature which are preset in relation to 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 the temperature change buttons (not shown) on the water discharge temperature setting panel 35 of each curran,
Backup RA is performed in advance by performing daily operations such as the spout water temperature increase instruction button 62 and the spout water temperature decrease instruction button 63 on the operation panel P, and the operation during construction of the water spouting device 1.
It is written in a predetermined address of M44. Note that this writing is interrupted when the corresponding button is operated, and is set according to each water discharge destination and water discharge mode.

Following the reading of the water discharge destination, etc., the flow rate sensors 7, 9 and the temperature sensors 11, 1 in the hot and cold water mixing tap UM.
The temperature and flow rate of the water itself and the temperature and flow rate of the hot water in the inflow pipe 3 and the inflow pipe 5 are read from the sensors such as 3 and the discharge water temperature is read from the temperature sensor 25 provided in the confluent flow path 23 (S120). .. At this time, the confluent flow path 23
The control signal corresponding to the detected water discharge temperature in 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 and the detected values from the respective sensors read in S120 (S1).
30). Then, the flow rate adjustment amounts of the flow rate adjusting valves 15 and 17 corresponding to the calculated flow rates, that is, the drive amounts of the actuator 19 and the actuator 21 are calculated (S140). Next, a drive signal is output to each actuator in order to execute the water discharge of the water discharge amount and the water discharge temperature read in S110 from the water discharge destination read in S100 (S).
150). Receiving 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. ..

Then, it is judged whether or not the water discharge destination read in S100 is the shower head S (S155).
Here, if it is determined that the water spouting destination is other than the shower head S (in the present embodiment, the washing place Karan AK or the bath Karan BK), it corresponds to the water spouting destination (either the washing place 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, whereby the water discharge destination controlled to be switched (either the washing place Karan AK or the bath Karan BK).
From S, the mixed hot water adjusted to the set water discharge amount and the set water discharge temperature is discharged in S150. In other words, if the spouting point is each of the washing section Karan AK or Bath Karan BK,
Since there is no obstacle in starting the water discharge, the corresponding solenoid valve is driven and the water is immediately discharged from the current portion.

After the water is discharged in this way, the process proceeds to S100 and the above-described processing is repeated. Therefore, if the spouting destination determined in S100 is each of the washing part curran AK or the bathing calan BK, when spouting is started from that spouting destination, the spouting water is discharged until the code of the spouting destination map relating to this spouting 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, S in the flowchart shown in FIG.
Move to 165. In this step S165, there is an instruction to change the water spouting form depending on whether or not the singing designating button 57, the straight designating button 58, the foam designating button 59, the mist designating button 60 of the operation panel P and the water spouting configuration selection button 84 of the shower head S are operated. Determine whether or not. Here, if the above buttons are not operated, it is not necessary to change the water discharge form 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 the process proceeds to S100. That is, even if the water spouting destination is the shower head S, if there is no need to change the spouting form, that is, if the spouting nozzle 80 is rotated to change the water spouting nozzle, there is no obstacle in starting spouting. Water is immediately discharged from the shower head S by driving the valve. Then, until the code of the water discharge destination map regarding the shower head S becomes 0, the water discharge from the shower head S is continued in the same water discharge form.

However, if it is determined in S165 that the water discharge form from the shower head S needs to be changed, first, the water discharge switching unit 27 corresponding to the water discharge destination other than the shower head S (either the washing place currant AK or the bath currant BK). A drive signal (ON signal) is output to the solenoid valve (S180), and then a drive signal (OFF signal) is output to the solenoid valve of the water discharge switching unit 27 corresponding to the shower head S (S190). That is, when the spouting destination is the shower head S and the spouting form is to be changed, the spouting start from the spouting destination other than the shower head S (either the washing place currant AK or the bath currant BK) and the shower head S The interruption of the water discharge is sequentially executed in this order.

Then, it is judged whether or not the change of the water discharge form due to the rotational drive of the rotary water discharger 80 is completed (S19).
5). This determination is made based on the presence / absence of input of a water discharge form change completion signal from the electronic control device on the shower head S side.
Here, if it is determined that the change of the water discharge form has not been completed, it is determined that the water discharge from the shower head S in the water discharge form instructed to be changed cannot be started, the process proceeds to S100 described above, and the process of each step described above is performed. , Continue until the change of water discharge form is completed. That is, the start of water discharge from the shower head S is waited until the rotation of the rotary water discharge body 80 is completed, and water is discharged from a water discharge destination other than the shower head S.

On the other hand, if it is judged in S195 that the change of the water discharge form is 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 process proceeds to the next S200. To 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. After that, a drive signal (OFF signal) is output to the electromagnetic valve of the water discharge switching unit 27 corresponding to the water discharge destination (either the washing place Karan AK or the bath Karan BK) other than the shower head S (S210),
The process moves to S100. That is, after the change of the water discharge form is completed, the water discharge from the shower head S and the water discharge from the water discharge destination other than the shower head S (either the washing place Karan AK or the bath Karan BK) are sequentially executed in this order. To do.

Therefore, the water discharge from the shower head S in the water discharge form 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 form instructed to change is continued until the code of the water discharge destination map regarding the shower head S becomes 0, or until the water discharge form is again instructed to change. It will be.

Next, the water discharge form changing routine will be described. This water discharge form changing routine is performed by the singing designation button 57 and the straight designation button 5 on the operation panel P.
8. Every 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 on the shower head S side executes an interrupt.

When the water discharge form changing routine is executed in this way, as shown in FIG. 7, first, 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 form, or a shower. It is determined whether it is based on the 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 N of times of operation (S31).
0), and proceeds to S330, which will be described later.

On the other hand, if it is determined that the change instruction is given from each of the buttons on the operation panel P, it is determined from the water discharge type detection sensor whether the current water discharge form from the shower head S is the water discharge form instructed to be changed. A determination is made based on the detection signal (S315). If an affirmative decision is made here, this routine is terminated without performing any processing. However, if a negative determination is made, the amount of rotation of the rotary water discharger 80, that is, the drive amount of the motor 77, required to change the current water discharge form determined by the water discharge form detection sensor to the water discharge form instructed to be changed is calculated (S320). ). For example, as shown in FIG. 4, when the current water discharge form is straight and the water discharge nozzle 80a faces the water discharge hole 82a to the water discharge window 73, if the change is instructed, the water discharge nozzle Drive amount until 80b exposes the water discharge hole 82b to the water discharge window 73 (180
Rotational drive amount) 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 discharge 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 changing the water discharge form described above, it is determined whether or not the rotary water discharger 80 has rotated 180 degrees and the water discharge nozzle 80b has reached the position where the water discharge hole 82b faces the water discharge window 73, and waits until then. .. If it is determined that the change to the instructed water discharge form is completed, a water discharge form change completion signal is output to the electronic control unit SS (S34).
0), this routine is ended once.

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

As described above, the water discharger 1 of this embodiment
For changing the spouting form when changing the spouting to another spouting form while spouting the mixed hot water from the shower head S in the spouting, straight, foam, or mist spouting form. Prior to the drive control of the rotary water spouting body 80, the spouting switching unit 27 is controlled to switch the spouting destination of the mixed hot water to a spouting destination other than the shower head S (either the washing place currant AK or the bath currant BK). That is, before driving the rotary water spouting body 80 to change the water spouting form, the mixed hot and cold water spouted from the shower head S up to that point is spouted from either the washing place currant AK or the bath currant BK.

When the drive control of the rotary water spouting body 80 for changing the water spouting form is completed, the water spout switching unit 27 is controlled to switch the spouting destination of the mixed hot water to the shower head S.
In this way, the mixed hot water is discharged from the shower head S in the changed water discharge form.

Therefore, while the rotary water discharger 80 is being driven, the discharge of the mixed hot water from the shower head S is interrupted, and the discharge of the mixed hot water is performed from the other outlets. As a result, according to the water discharger 1 of the present embodiment, the rotary water discharger 80 can be driven in 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 are 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, the size of the motor 77, which is the drive source of the rotary water discharger 80, can be reduced, so that the shower head S can be made smaller and its usability can be improved.

In addition, the rotary water spouting body 8 for changing the water spouting form.
When switching the water discharge destination before driving 0, the start of water discharge from the water discharge destination other than the shower head S and the interruption of the water discharge from the shower head S were sequentially executed in this order. The flow rate adjusting valve 17 in the hot water inflow pipe 5 does not perform flow rate adjustment (zero flow rate) for a sudden change in the adjustment 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 can be implemented in various modes without departing from the scope of the present invention. Of course.

For example, in the above-mentioned embodiment, the spouting target of the switching target before driving the rotary spouting body 80 for changing the spouting form is either the washing place currant AK or the bath currant BK, but it is configured as follows. You can also That is, the so-called sewage water pipe for so-called sewage water, which is directly connected to the drainage pipe for discharging the drainage in the bathroom to the outside, is used as the water discharge switching unit 2
7 and connect the water discharge destination to be switched to
Instead of K or Bascaran BK, this all-water pipe can be used.

Further, when the discharge destination of the mixed hot water is returned to the shower head S, it is configured to wait for the completion of the drive control of the rotary water discharge body 80, that is, to confirm the completion of the drive. It is also possible to adopt a configuration in which the above-mentioned returning operation is performed when a predetermined time has elapsed after the water discharge destination was switched to other than the shower head S.

[0062]

As described in detail above, the water spouting device of the present invention can be used in the case of changing the spouting water to another spouting form while spouting the mixed hot water from the spout built in the drive section in a certain spouting form. The water discharge destination of the mixed hot water is a water discharge destination other than the drive unit built-in water discharge outlet while the drive unit is drive-controlled to change the water discharge mode.

Therefore, while the drive unit is being driven and controlled, the discharge of the mixed hot water from the drive unit built-in spout is interrupted, and the spout of the mixed hot water from the other spouts is performed. As a result, according to the water discharger of the present invention, it is possible to drive the drive unit that is driven in the inflowing fluid path in a low load state in which no fluid is flowing in, and drive any control accompanying adjustment of the mixed hot and cold water temperature. Since it is not necessary before and after the drive control of the unit, it is possible to change the spouting form of the mixed hot water from the spout port built into the drive unit in a short time.
