DISCLOSURE OF INVENTION Problems to be Solved by the Invention For example, in a water discharger having a shower head, hot water and hot water from a water heater are mixed by a hot and cold water mixing tap, and the discharge amount thereof is as described above. The water is discharged from the shower head while being periodically changed by the flow rate adjusting valve. Therefore, the following problems have been pointed out.

When the mixed hot water from the shower head is discharged while periodically changing the amount of water discharged, it is necessary to control the flow rate adjusting valve so that the amount of water discharged is reduced in the process of periodically changing the amount of water discharged. is there. When controlling the flow rate adjusting valve to reduce the water discharge amount in this way, a rapid decrease in the water discharge amount may cause a misfire of a water heater that supplies hot water, which is not preferable.

The flow rate adjusting valve is provided independently in the hot water and hot water pipes reaching the hot and cold water mixing tap,
Although it is provided in the pipe of the mixed hot and cold water downstream of the hot and cold water mixing valve, the flow rate adjusting valve provided at any position has such a problem.

The present invention has been made to solve the above problems, and an object thereof is to avoid the inconvenience caused by a sudden change in the water discharge amount when the water discharge amount is periodically changed.

[0007]

Means for Solving the Problems In order to achieve such an object, the means adopted by the present invention includes a water discharge amount variable water discharge port for which it is desired to periodically change the water discharge amount, and a water discharge port other than that. A water spouting device for spouting fluid supplied from a fluid supply source from any of the water spouts, wherein the spouting device is configured to add water to the spouting amount variable spouting port while spouting water from the water spouting amount variable spouting port. In the case where a plurality of water spout water spouting means for spouting water from a water spout other than the variable water spouting volume, and the water spouting variable water spouting port and the other water spouts are being spouted by the plurality of water spout water spouting execution means The gist of the present invention is to further include a water discharge amount changing means for periodically changing the water discharge amount from any one of the water discharge amount variable water discharge port and the other water discharge ports.

[0008]

In the water spouting device having the above-described structure, the plural water spouting water spouting execution means spouts water from the water spouting port other than the variable water spouting amount spouting port while spouting water from the water spouting amount variable spouting port. At this time, the water discharge amount changing means periodically changes the water discharge amount from either the water discharge amount variable water discharge port or the other water discharge port.

Therefore, if the water discharge port whose water discharge amount changes periodically is a water discharge amount variable water discharge port, the water discharge from the water discharge amount variable water discharge port naturally becomes the water discharge whose water discharge amount changes periodically. On the other hand, even if the spout whose amount of water discharge changes periodically is a spout other than the variable spout, the spout from the variable spout is periodic from the spout other than the variable spout. Under the influence of a large change in the amount of water discharged, the amount of water discharged changes periodically. When the amount of water discharged changes cyclically in this way, it is not necessary to suddenly change the total amount of fluid supplied from the fluid supply source to the variable amount water outlets and the other outlets.

And a group of buttons for periodically changing the amount of water discharged from the shower head S.

A button group for setting the water discharge amount and the water discharge temperature includes a setting button 61 provided in the lower stage of each of the designation buttons for designating the water discharge form, and an increase in the water discharge temperature provided above and below the left and right of the setting button 61. An 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 included. Setting button 61
When changing the water discharge temperature or the water discharge amount, is pressed before and after the change operation to output a control signal for starting and ending the change to the electronic control unit SS, and then the water discharge temperature increase instruction button 62.
Each of the instruction buttons such as outputs a control signal corresponding to the amount of water discharge or the amount of change in the water discharge temperature to the electronic control unit SS. The electronic control unit SS which has received this 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 after the setting button 61, the water discharge temperature or 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 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 discharge form, water is discharged from the shower head S in a water discharge form corresponding to the pressed designation button. The manner of changing the water discharge form will be described later in detail.

The spout water temperature setting panels 35 and 37 of the washing place Karan AK and the bath currant BK change the spouting designation button for switching the spouting water among the water, the temperature-controlled mixed hot water and hot water, and the spouting temperature during the mixed hot water spouting. 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 faces 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. Further, in the thick wall 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. An on / off button 85 for instructing the start / stop of water discharge is covered by a waterproof resin sheet 86 and arranged so as to be freely pressed.

The electronic control device on the shower head S side is connected not only to the above-mentioned sensors and buttons, but also to the electronic control device 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 turned 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 configuration will be described with reference to the drawings.

The flowcharts of FIGS. 5, 6 and 7 are as follows.
Water discharge control (routine), which is the main control of the water discharge device 1.
8 shows a water spouting form change control (routine) when the water spouting form is changed by the water spouting form selection button 84 of the shower head S, the singing designation button 57 of the operation panel P, or the like.

The flowcharts of FIGS. 5 and 6 show the first half and the latter half of the water discharge routine, and the flowchart of FIG. 7 shows a part of the processing of the latter half. 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. The writing of the code of the value 1 is performed by pressing a button such as the bath currant instruction button 54 on the operation panel P, a water spouting designation button on the spout water temperature setting panel of each currant, 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, the water discharge form map is similar to the water discharge destination map in that 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 valve UM are read.
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 discharge 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 discharge 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 27a or 27b 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, so that the water discharge destination that has been controlled to be switched (washing place Karan AK or bath Karan B).
From any of K), the mixed hot water adjusted to the set water discharge amount and the set water discharge temperature is discharged in S150. That is,
If the spouting destination is each of the scrubbers of the washing place currant AK or the bath currant BK, there is no obstacle in starting the spouting, so the corresponding solenoid valve 27a or 27b is driven to immediately discharge the water from the currant portion.

After the water is discharged in this way, the process proceeds to S100 and the above-mentioned 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 spouting 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. Next, the period is set when the amount of water discharged from the shower head S is changed cyclically. It is determined whether or not there is (S170).

This judgment is made by the water discharge amount short cycle setting button 66.
Based on the pressed state of each cycle setting button, such as That is, if any one of the cycle setting buttons is pressed, it is determined that the water discharge amount change cycle needs to be set. If no cycle setting button is pressed, it is determined that the water discharge amount does not need to be changed. , A drive signal (ON signal) is output to the electromagnetic valve 27c of the water discharge switching unit 27 corresponding to the shower head S (S178), and then S1.
00.

On the other hand, when it is judged that it is necessary to set the water discharge amount change cycle, as shown in FIG. 7, the water discharge amount change cycle (short cycle, middle cycle, large cycle) corresponding to the pressed cycle setting button. Cycle) is read from the ROM 42 (S17)
2) The drive signal / stop signal (ON / OFF signal) is output at the read cycle to the electromagnetic valve 27d that opens and closes the conduit between the fresh water pipe SH and the confluent flow path 23, and the electromagnetic valve 2
A drive signal (ON signal) is output to 7c (S175),
Then, the process proceeds to S100.

In other words, even if the water spouting destination is the shower head S, if there is no need to change the water spouting form, that is, the water spouting nozzle by the rotation of the rotary water spouting body 80, there is no obstacle in starting the water spouting. Therefore, the solenoid valve 27
Water is immediately discharged from the shower head S by driving c. However, when the amount of water discharged from the shower head S is periodically changed, the shower head S via the solenoid valve 27c is used.
In addition to spouting water from the water supply pipe, through the drive / stop of the solenoid valve 27d according to the cycle corresponding to the cycle setting button,
Water from H outside the bathroom. And the shower head S
Until the code of the water discharge destination map regarding 0 is set to 0, the water discharge from the shower head S is continued in the same water discharge form, and periodical water is also discharged in parallel.

On the other hand, 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 the water discharge destination other than the shower head S (either the washing place currant AK or the bath currant BK). Output a drive signal (ON signal) to the solenoid valve 27a or 27b of
180) and thereafter, a drive signal (OFF signal) is output to the electromagnetic valve 27c of the water discharge switching unit 27 corresponding to the shower head S (S190). That is, the spouting destination is the shower head S
When changing the water discharge form, 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) and the interruption of the water discharge from the shower head S are performed in this order. To execute sequentially.

Then, it is determined 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, until the rotation of the rotary water discharger 80 is completed, the water discharge from the shower head S is in the standby state, and the water discharge from the water discharge destination other than the shower head S is in the executable state.

On the other hand, if it is determined in S195 that the change of the water discharge form is completed based on the water discharge form change completion signal, in the changed water discharge form, the amount of water discharged from the shower head S is periodically changed in the same manner as in S170. It is determined whether or not the cycle has been set when changing (S19).
8). Here, if an affirmative decision is made, S172 and S1 of FIG.
After processing 74, the water discharged from the shower head S and the water discharged from the water pipe SH are moved in parallel to S100, and if a negative determination is made, the shower head S in the water discharge form instructed to be changed is discharged. The next S2
00.

In S200, a drive signal (ON signal) is output to the electromagnetic valve 27c of the water discharge switching unit 27 corresponding to the shower head S. After that, the electromagnetic valve 27a or 27 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.
The drive signal (OFF signal) is output to b (S210), and S1
00. That is, after the change of the water discharge form is completed,
The start of water discharge from the shower head S and the water discharge destinations other than the shower head S (washing place Karan AK or bath Karan BK
(Either of the above) and the interruption of the water discharge from the above are sequentially executed in this order.

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 manner, as shown in FIG. 8, 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 discharger 80 is output.
To rotate.

Then, it is judged 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 way, the electronic control unit SS that receives this signal determines that the change of the water discharge form has been completed in S195 in the above water discharge routine, and as described above, after S198. The process of 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. Moreover, the water discharge from the shower head S is performed while periodically changing the water discharge amount.

As described above, the water discharger 1 of this embodiment
If it is necessary to periodically change the amount of water discharged from the shower head S while the mixed hot water is being discharged from the shower head S, in addition to the water discharged from the shower head S, the water pipe SH The water is drained from the water while the amount of water discharged (the amount of ground water) is cyclically changed by turning on / off the electromagnetic valve 27d in the water discharge amount change cycle corresponding to the cycle setting button. However, at this time, the flow rate adjusting valve 1 in the water inflow pipe 3 and the hot water inflow pipe 5 reaching the merging flow path 23
Since the flow rate adjustment by 5 and 17 remains the same, the flow rate of the mixed hot water passing through the confluent flow path 23 is substantially constant at the set discharge amount. Therefore, the amount of water discharged from the shower head S via the electromagnetic valve 27c that is in the open state by the ON signal and the electromagnetic valve 27d that repeats opening and closing by the periodic ON / OFF signal, and then the water pipe SH The sum of the amount of slush water to be watered is equal to the flow rate of the mixed hot water passing through the merging passage 23 and is unchanged.

As a result, the sum of the amount of water discharged from the shower head S and the amount of slaked water from the sewage water pipe SH is constant, and the amount of slaked water from the spill water pipe SH changes periodically. Therefore, the water spouted from the shower head S is affected by the periodic change in the amount of sludge water from the fresh water pipe SH and becomes a water spout in which the amount of water spouted periodically changes. Therefore, according to the water discharger 1 of the present embodiment, even if the amount of water discharged from the shower head S is periodically changed, the amount of inflow of the hot water from the inflow pipe 5 is not suddenly changed. It is possible to avoid an unexpected situation such as a misfire of the water heater caused by the sudden change in the inflow amount in 5.

Further, in the water discharger 1 of the present embodiment, when the amount of slush water from the squeeze water pipe SH for periodically changing the amount of water spouted from the shower head S is periodically changed, the cycle thereof is changed. It is configured to select from short cycle, medium cycle, and large cycle according to the cycle setting button. That is, as shown in the timing chart of FIG. 9, while the water discharge from the shower head S is being continued at the set water discharge amount, the water discharge amount short cycle setting button 66 is pressed and the shower head S is discharged from the shower head S in a short cycle. If a change in the water discharge amount is desired, the opening / closing of the electromagnetic valve 27d by the ON / OFF signal is repeated from this point on in this short cycle to change the water discharge amount from the shower head S in a short cycle as shown in the figure. Further, if a change in the water discharge amount from the shower head S in the medium cycle and the large cycle is desired by the water discharge amount medium cycle setting button 67 and the water discharge amount large cycle setting button 68, the discharge from the shower head S is performed from those points. The amount of water is changed in a medium cycle or a large cycle. Therefore, according to the water discharger 1 of the present embodiment, the added value can be improved by diversifying the cycle in which the amount of water discharged from the shower head S is changed.

Moreover, when the amount of water discharged from the shower head S is cyclically changed in this way, the flow rate adjustment valves 15 and 17 in the water inflow pipe 3 and the hot water inflow pipe 5 do not need to be adjusted. The amount of water discharged from the shower head S can be periodically changed while keeping the temperature of the mixed hot and cold water determined by the respective temperatures of water and hot water and the mixing ratio thereof constant. As a result, the user who showers the spouted water whose amount of spouted water changes periodically from the shower head S does not feel uncomfortable due to the change in the spouted water temperature. That is, the usability can be improved.

Further, since it is possible to perform periodical changes in the amount of discharged water and perform any of the straight, foam, and mist discharge forms, it is possible to improve the added value and usability.

Further, according to the water discharger 1 of this embodiment, the following effects can be obtained. When changing from spouting, straightening, foaming, or mist to a different spouting form, the spouting switching unit 27 is controlled prior to the drive control of the rotary spouting body 80 for changing the spouting form, and the mixed hot and cold water is mixed. The water spouting destination is switched to a water spouting destination other than the shower head S (either the washing place Karan AK or the bath Karan 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 until then is washed with the washing place Karan AK or the bath Karan BK.
Spit water from either.

When the drive control of the rotary water spouting body 80 for changing the water spouting form is completed, the spouting 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 water 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 embodiment, in order to periodically change the amount of water discharged from the shower head S, the amount of slaked water from the slag water pipe SH is cyclically changed. The water discharge port that is periodically changed may be the bathcaran BK or the shower head S itself. If the water discharge port that periodically changes the water discharge amount is a bathcaran BK, so-called filling can be performed in the bathtub while periodically changing the water discharge amount from the shower head S.

As described above in detail, in the water discharge device of the present invention, while the water is being discharged from the variable water discharge amount water discharge port where it is desired to periodically change the water discharge amount, the water discharge amount is periodically changed. If it is necessary to change the water discharge amount, in addition to the water discharge from the water discharge amount variable water discharge port, the water discharge from the other water discharge ports is performed. At this time, water is discharged from either the water discharge amount variable water discharge port or the water discharge port other than the water discharge amount variable water discharge port while periodically changing the water discharge amount.

As a result, according to the water spouting device of the present invention, even if the amount of water spouted from the variable water spouting port is changed periodically,
Since it is not necessary to change the total supply amount of the fluid supplied from the fluid supply source to the variable water discharge amount water discharge port and the other water discharge ports in accordance with the above cycle, avoid the inconvenience caused by the sudden change in the water discharge amount. You can

Further, the variable water discharge amount water discharge port is a shower head provided in the bathroom, and the water discharge ports other than the variable water discharge amount water discharge port are drain pipes for discharging the drainage in the bathroom out of the room. When a water outlet other than a showerhead in a bathroom or a bathroom is used to periodically change the amount of water discharged from the showerhead, a misfire caused by a sudden change in the total amount of water discharged from the water heater, which is the supply source. Can be avoided in advance. In particular, if the water discharge port other than the variable water discharge amount water discharge port is used as the bathtub cullan, it is possible to fill the inside of the bathtub with the water discharged from the shower head in which the water discharge amount changes periodically.
