2. Description of the Related Art In recent years, in order to realize a comfortable living environment, it has become common to supply not only water but also hot water to water outlets of kitchens, washrooms, baths, and the like. At this time, using a control panel or the like, instead of a conventional system in which the user adjusts the mixing ratio of water and high-temperature water at the tapping point to obtain a proper-temperature water, such as a one-handed or two-handed hand set. A water spouting device that obtains hot water at a specified temperature has been proposed.
In such a water discharging device, a water discharging temperature and a water discharging amount are controlled by changing a mixing ratio of water and high-temperature hot water using a valve or the like capable of electrically controlling a flow rate.

As described above, in addition to making the water discharge environment comfortable based on the simple adjustment of the water discharge temperature and the water discharge amount, the water discharge form from the water discharge port is switched to diversify. For example, in a shower head in a bathroom, a water discharge form in which the water is discharged in a stick shape, a straight water discharge form,
Switching to a different water discharge mode such as a foam water discharge mode or a mist water discharge mode has been proposed. In addition, in switching the water discharge mode, an appropriate configuration is adopted, such as replacing the water spray plate in the shower head or preparing and replacing a plurality of shower heads having different water discharge modes.

However, the following problems have been pointed out in the above-mentioned conventional water discharging device. That is, since the user's preference, for example, the preferred water discharge temperature and water discharge amount for each water discharge mode, or the switching frequency of the water discharge mode is various, it is necessary to adjust the water discharge temperature and the water discharge amount every time the water discharge mode is switched. is there. In addition, bathing every day,
It is performed at least once every two or three days, and the water discharge mode is frequently switched each time. For this reason, the operation of the water discharging device accompanying the switching of the water discharging mode is troublesome.

[0005] The present invention has been made to solve the above problems, and has as its object to improve the operability associated with switching the form of water discharge from a water discharge port.

[0006]

In order to achieve the above object, a means adopted by the present invention is to provide a water discharge port which can be switched to a different water discharge form, a supply water and a supply water before reaching the water discharge port. Water discharge temperature adjusting means for adjusting the water discharge temperature by mixing;

Identification information specifying means for specifying information; and control for controlling the water discharge temperature adjustment means and the water discharge amount adjustment means based on the water discharge data group identified by the specified identification information and the water discharge form at the water discharge port. The main point is to provide means.

[0007]

In the water discharge device of the present invention having the above-described configuration, the water discharge temperature and the water discharge amount set for each water discharge form by the setting means are stored as a water discharge data group corresponding to the water discharge form set as the setting target. Store in the means. In addition, when storing the water discharge data group, it is stored together with identification information for identifying each water discharge data group. This makes it possible to identify each water discharge data group based on the identification information.

When the identification information is specified by the identification information specifying means, the control means controls the water discharge temperature adjusting means on the basis of the water discharge data group identified through the specified identification information and the water discharge form at the water discharge port. And the water discharge amount adjusting means. As a result, if the identification information is specified when water is discharged from the water discharge port, even if the water discharge form is switched, the identification information is identified via the identification information specified by the identification information specifying means in the water discharge data group including the water discharge form. The discharged water data group can be used for the discharged water temperature adjustment by the discharged water temperature adjusting means and the discharged water amount by the discharged water amount adjusting means.

In addition to the foam designation button 59 and the mist designation button 60,
The following buttons are provided for presetting the water discharge temperature and water discharge amount for each water discharge destination and water discharge form, and changing the water discharge amount and water discharge temperature of the continuous water discharge each time. In addition, on the surface of each of the above-mentioned buttons and each of the buttons described below, as shown in the figure, in addition to a character string, a picture in which the corresponding function is designed is written.

A setting button 61, which is pressed when setting the water discharge temperature and the water discharge amount, is provided below the above specification buttons for specifying the water discharge form. Further, on the left and right sides, a water discharge temperature increase instruction button 62, a water discharge temperature decrease instruction button 63, a water discharge amount increase instruction button 64, a water discharge amount decrease instruction button 65, and when the set water discharge temperature and water discharge amount are registered, A registration button 66 to be pressed is provided.

A water discharge temperature or water discharge amount instruction button such as a water discharge temperature increase instruction button 62 is used in combination with the setting button 61 and the registration button 66 to set and register the water discharge temperature and water discharge amount for each water discharge destination and water discharge form. If the water discharge operation is performed independently while the water discharge is continued, the function of changing the water discharge amount and the water discharge temperature of the continuous water discharge is performed.

That is, if the water discharge temperature increase instruction button 62 or the like is pressed alone during the continuation of the water discharge, the signal is input to the electronic control unit SS, and the electronic control unit SS receiving the signal is received.
Thus, each time, the temperature of the continuously discharged water and the amount of the discharged water are changed according to the number of times the button is pressed. In this case, in addition to the water temperature, the water discharge temperature can be changed in a temperature that is commonly used during bathing and is in a safe temperature range (38 to 46 degrees). In consideration of the amount of water discharged and the capacity of the water heater, etc., each water outlet and water discharge form are determined as follows.

Water discharge amount variable range for straight water discharge form in shower water discharge: 6 to 18 liters / min. Water discharge amount variable range for foam water discharge form in shower water discharge: 2 to 14 liters / min. Water discharge amount variable range for water discharge form: 2 to 14 liters / min. Also, the water discharge temperature and the water discharge amount are beyond these water discharge temperature range and water discharge amount range.

The change of the water discharge temperature and the water discharge amount during the water discharge is not directly related to the gist of the present invention, and the description thereof will be omitted. On the other hand, the water discharge temperature increase instruction button 62
The state of registration of the water discharge temperature and water discharge amount when the setting button 61 and the registration button 66 are used together will be described in detail using a water discharge data registration routine (FIG. 7) described later.

Here, the water discharge temperature increase instruction button 62
The functions performed by buttons other than the instruction buttons such as, will be briefly described. When a push-type bus curran instruction button 54 or the like for individually specifying a water discharge destination or a squat specification button 57 or the like for specifying a water discharge mode is pressed, the signal is input to the electronic control unit SS, and The water discharge destination and the water discharge mode are switched by the received electronic control unit SS. For example,
When the bath curan instruction button 54 is pressed, water is spouted from the curan section 33 of the bath curan BK. Similarly, when the wash curn instruction button 55 or the shower head designation button 56 is pressed, the wash curn AK or the shower head S is pressed.
It is spouted from. Moreover, if a designation button for designating a different water discharge destination is pressed while water is being discharged from a certain water discharge destination, the water discharge from the above-mentioned water discharge destination that has been discharging water until then is interrupted, and The water is discharged from the corresponding water discharge destination. Similarly, water is discharged from the shower head S in the water discharge mode corresponding to the pressed specification button for each of the specification buttons for specifying the water discharge mode.

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 rotary 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.

Therefore, 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 made to face the water discharge window 73 by the motor 77, the hot 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.

Equipment storage space 7 of 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 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 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 this case, the drive of the actuators 19 and 21 of the flow control valves 15 and 17 is also controlled by the electronic control unit SS.

Further, the slap designation button 57 and the straight designation button 5 on the operation panel P attached to the shower tower ST.
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 to instruct the change of the water discharge mode, the electronic control unit SS and the electronic control unit on the shower head S side switch between them. A control signal is transmitted and received. 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 sending and receiving such signals,
The drive of the motor 77 is controlled by the electronic control unit on the shower head S side, and the water discharge nozzle rotates, and the water discharge nozzle corresponding to the selected water discharge form is moved through the water discharge hole to the water discharge window 73.
And stop.

Next, various controls performed by the water discharge device 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 flow chart of FIG. 7 shows the water discharge data registration control (routine) for pre-registering the water discharge temperature and the water discharge amount at the time of water discharge of the mixed hot water according to the preference of the user.
Further, the flowchart of FIG. 8 shows a water discharge data update control (routine) for updating the water discharge temperature and the water discharge amount to those according to the user's preference prior to the water discharge of the mixed hot water.

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.

Similarly to 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, for the four water discharge forms from the shower head S (song, (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 set water discharge temperature T0 and the set water discharge amount Q0, which have already been set 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 Q0 and the set water discharge temperature T
0 is a control target value to be adjusted at the start of water discharge or during water discharge, and can be changed in the above temperature range or water discharge amount range. These data are stored in the water discharge temperature setting panel 35 of each curan, in addition to a temperature change button (not shown), and a water discharge temperature increase instruction button 6 on the operation panel P.
2. The backup RAM is updated each time by daily operation of the water discharge temperature lowering instruction button 63 or the like, or updated by processing of a water discharge data update routine described later.
It is written to a predetermined address of 44. Note that this writing is interrupted when the corresponding button is operated, and is updated in accordance with each water discharge destination and water discharge mode in the water discharge data update routine.

Subsequent to the reading of the water discharge destination, etc., the flow sensors 7, 9 and the temperature sensors 11, 1 in the hot / water mixer tap UM are read.
3, 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, and the temperature of the mixed hot water is read from the temperature sensor 25 provided in the merging flow path 23 (S120). ). At this time, a control signal corresponding to the detected water discharge temperature in the merging flow path 23 is output to the operation panel P and the water discharge temperature setting panel of each callan, and the temperature is output to the water discharge temperature indicator 53 of the operation panel P and the water discharge temperature display of each callan. This is displayed on a group of LED indicators (not shown) of the water discharge temperature setting panel.

Next, the set water discharge amount Q read in S110
The flow rates of water and hot water are calculated based on 0, the set water discharge temperature T0, and the detection values from the respective sensors read in S120 (S130). 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 set water discharge amount Q0 and the set water discharge temperature T0 read at S110 from the water discharge destination read at S100 (S150). 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).
From step S150, the set water discharge amount Q0 and the set water discharge temperature T
The mixed hot water adjusted to 0 is discharged. In other words, if the destination of the water discharge is each of the callains KARAN AK or BASKARAN BK, there is no obstacle in starting the water discharge, and the corresponding electromagnetic valve is driven to immediately discharge the water from the callan.

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 change of the water discharge form from the shower head S is necessary, first, the water discharge switching unit 27 corresponding to the water discharge destination other than the shower head S (either the wash basin AK or the bath cull 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. The rotation drive control of the rotary water discharger 80 is performed by the electronic control device on the shower head S side, but details thereof are not directly related to the gist of the present invention, and therefore, the description thereof is omitted.

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 water discharge from the shower head S in the water discharge form instructed to be changed can be started, and the process proceeds to 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 be changed is performed at the set water discharge amount Q0 and the set water discharge temperature T0. 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, a water discharge data registration routine for pre-registering the water discharge temperature and the water discharge amount at the time of discharging the mixed hot water according to the user's preference will be described with reference to the flowchart shown in FIG. This water discharge data registration routine is an interruption process when the setting button 61 on the operation panel P of the shower tower ST is pressed, and sets and sets the water discharge temperature and the water discharge amount in the shower water discharge.
Registration is performed for each water discharge mode.

When the setting button 61 is pressed and the water discharge data registration routine is executed, first, the pressing state of the water discharge form specifying buttons such as the singing designation button 57 and the straight designation button 58 on the operation panel P is scanned and registered. The target water discharge mode is determined (S300). Subsequently, the reference adjustment amount (the reference water discharge temperature T
k, the reference water discharge amount Qk) is read from the ROM 42, and is displayed on the water discharge temperature display 53 and the water discharge amount display 52 (S310). The reference water discharge temperature Tk and the reference water discharge amount Qk
Are stored in the ROM 42 in advance for each water discharge mode.

For example, if it is determined from the pressing state of the water discharge mode designating button that the water discharge mode to be registered is the squatting water discharge mode, the reference adjustment amount (reference water discharge temperature Tk, reference water discharge amount Qk) relating to this water discharge mode. 40 degrees and 10 liters / minute are read from the ROM 42, a numerical value 40 is displayed on the water discharge temperature display 53, and a relative display is displayed on the water discharge amount display 52. Read and display at 42 degrees and 12 liters / minute for straight, 40 degrees and 8 liters / minute for foam, and 46 degrees and 8 liters / minute for mist. Do each.

Thereafter, a registration adjustment amount (registered water discharge temperature T1, registered water discharge amount Q1) desired by the user is set for the water discharge of the water discharge form determined in S300 (S320). Specifically, the registered water discharge temperature T1 and the registered water discharge amount Q1 are determined based on the number of times of operation of each of the instruction buttons such as the water discharge temperature increase instruction button 62 and the water discharge amount increase instruction button 64, and the determined adjustment amounts are stored in the RAM 43. Is stored in a registration data setting table as shown in FIG. For example,
If the water discharge form determined in S300 is a squatting water discharge form and the registered water discharge temperature T1 and the registered water discharge amount Q1 based on the number of times of operation of each of the above-mentioned instruction buttons are 44 degrees and 14 liters / minute, these data are given. Is stored in association with the water discharge mode of the above.

Subsequently, the above-mentioned certain water discharge form (song)
After the setting of the registration adjustment amount for, whether the setting of the registration adjustment amount is to be continued for other water discharge modes is determined by pressing a water discharge mode designation button such as the straight designation button 58 or the numeric key of the key group 67. It is determined whether or not is pressed (S325).

If the water discharge mode designation button is pressed, the process from S300 is repeated by assuming that the registration adjustment amount is set for the water discharge mode corresponding to the pressed button, and if the numeric key is pressed, It is determined that the registration adjustment amount has been set, and the process proceeds to the next step. That is, the setting of the registration adjustment amount is repeated for all the water discharge modes desired by the user.

When the setting of the registration adjustment amount is completed for all the water discharge modes in this way, water discharge data in which each water discharge mode is associated with the registered adjustment amount is created as shown in FIG. In the registration data setting table of FIG. 9, the reference adjustment amounts (the reference water discharge temperature Tk, the reference water discharge amount Q
k) is set. Therefore, for the water discharge mode in which the user does not want to set the registered adjustment amount, the reference adjustment amount (reference water discharge temperature Tk, reference water discharge amount Qk) related to the water discharge mode.
Is the registration adjustment amount.

If the numeric key is pressed in S325, it is determined that the setting is completed, and the numeric value of the pressed numeric key is identified by the identification number. Is stored in the RAM 43 (S330). After that, it is determined whether or not the stored numerical value (identification No.) of the numerical key and the set registration adjustment amount are registered in association with each other based on whether or not the registration button 66 is pressed (S335), and the registration button 66 is pressed. Wait until. When the registration button 66 is pressed, the stored numerical value (identification number) of the numerical key is associated with the water discharge mode and the set registration adjustment amount, respectively.
The registration data table shown in FIG. 10 is updated and stored (S
(340) The process of this routine is temporarily terminated.

This registration data table is stored in the range from 00 to 10
11 identification numbers up to Is provided over a predetermined area of the backup RAM 44 so that the registered adjustment amount (registered water discharge temperature T1, registered water discharge amount Q1) for each water discharge mode can be stored. In addition, at the time of shipment from the factory, all identification Nos. The above reference adjustment amounts (reference water discharge temperature Tk, reference water discharge amount Qk) are stored for each water discharge mode. Therefore, as shown in FIG. 10, the identification No. for which the registration adjustment amount has not been set. (09, 10)
, The reference adjustment amount remains unchanged.

By repeating the processing from S300 to S325, the registration adjustment amount is set for each water discharge mode as shown in FIG.
Is stored as the identification number in FIG. "0
In "0", each registered adjustment amount for each set water discharge mode is written and stored.

Next, prior to the mixed hot water spouting, the spouting water temperature and the spouting amount are determined according to the user's preference (the registered spouting water temperature T).
A description will now be given, with reference to the flowchart of FIG. 8, of a water discharge data update routine for updating to the registered water discharge amount Q1).
This water discharge data updating routine is an interruption process when the character keys of * and # in the key group 67 of the operation panel P are pressed, and the set water discharge temperature T0 and the set water discharge amount Q0 in the shower water discharge are set to each water discharge. Update on form.

When any of the above character keys is pressed to execute the water discharge data updating routine, it is first determined whether the pressed character key is a character key of * or a character key of # (S400). .

Here, if it is determined that the character key is *, it is subsequently determined whether or not a numeric key is input (S40).
5) Wait until a numeric key is input. If there is an input of the numerical key, the numerical value by the input numerical key is determined (S410), and the identification number matching the determined numerical value is determined. Registration adjustment amount (registered water discharge temperature T1, registered water discharge amount Q1)
Is read from the registration data table of FIG. 10 (S42).
0). Then, the set adjustment amounts (set water discharge temperature T0, set water discharge amount Q0) for all the water discharge forms are updated to the read registered adjustment amounts (registered water discharge temperature T1, registered water discharge amount Q1), and the predetermined addresses in the backup RAM 44 are updated. (S430), and this routine is once ended.

On the other hand, if it is determined in step S400 that the # character key has been pressed, the reference adjustment amounts (reference water discharge temperature Tk and reference water discharge amount Qk) for each water discharge mode are read from the ROM 42 (S440). Thereafter, the reference adjustment amounts (reference water discharge temperature Tk, reference water discharge amount Q) from which the set adjustment amounts (set water discharge temperature T0, set water discharge amount Q0) for all the water discharge modes are read.
k), and writes it to a predetermined address in the backup RAM 44 (S450), and terminates this routine once.

When the set water discharge temperature T0 and the set water discharge amount Q0 relating to each water discharge form are updated and written in S430 or S450, S110 in the water discharge routine is executed.
The set water discharge temperature T0 and the set water discharge amount Q0 after updating in FIG.
Is read, and the read water discharge temperature and water discharge amount (registered water discharge temperature T1, registered water discharge amount Q1, or reference water discharge temperature Tk,
The flow rates of the water and hot water are calculated so as to be equal to the reference water discharge amount Qk) (S130), and based on this, the flow control valves 15 and 17 are controlled.

As described above, the water discharge device 1 of the present embodiment
Is a method in which a registered adjustment amount (registered water discharge temperature T1, registered water discharge amount Q1) set as desired by the user for each water discharge form is associated with the water discharge form and converted into data, and this data is identified by an identification number specified by a numerical key. . Is stored so that it can be identified. The set water discharge temperature T0 and the set water discharge amount Q0, which are the control target values at the time of shower water discharge in each water discharge mode, are identified by the identification No. input for each user. The registered water discharge temperature T1 and the registered water discharge amount Q1 specified by.

As a result, according to the water discharge device 1 of the present embodiment, in performing the shower water discharge from the shower head S, the identification number unique to the user. If you key in
The shower water discharge for all water discharge modes can be performed at the water discharge temperature and water discharge amount desired by the user, and it is not necessary to set the water discharge temperature and the water discharge amount every time the water discharge mode is switched. In addition, a user who newly performs shower water discharge in the water discharge device 1 has only one identification number when taking shower water discharge. Key input. Therefore, according to the water discharge device 1 of the present embodiment, it is possible to improve the operability associated with switching the water discharge mode of the shower water discharge.

Even if the registered adjustment amount (registered water discharge temperature T1, registered water discharge amount Q1) has been set and stored, the adjustment to the registered adjustment amount is stopped only by pressing the # character key, and the total adjustment amount is stopped. The shower water discharge for all water discharge modes can be performed with the reference adjustment amount (reference water discharge temperature Tk, reference water discharge amount Qk). Therefore, according to the water discharge device 1 of the present embodiment, the so-called initialization of the set adjustment amount can be easily performed.

Further, the rotary water discharge body 8 is used for changing the water discharge form.
