In addition, the operation panel P has the above-mentioned water discharge temperature so that the water discharge temperature from the shower head S can be switched and the water discharge amount per unit time from each currant and the shower head S (hereinafter, simply referred to as water discharge amount) can be set. Although a button and the like not provided on the setting panel are provided, they are not directly related to the gist of the present invention, and thus the description thereof is omitted.

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 flow chart of FIG. 4 shows the water discharge control (routine) which is the main control of the water discharge device 1, and the flow charts of FIGS. 5 to 10 show the water discharge from each of the water discharge temperature setting panels of the washing place currant AK and the bath currant BK. 9 shows a discharge water temperature switching control (routine) when a temperature switching instruction is given. The flowchart of FIG. 11 shows a mixed hot water temperature change control (routine) that changes the water discharge temperature during the discharge of the mixed hot water within a predetermined range.

The water discharge routine of FIG. 4 is repeatedly executed 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, etc. Then, as shown in FIG.
Load the data of the water discharge destination map that specifies the water discharge destination,
The spouting destination is determined (step 100: hereinafter, the step is simply referred to as S). This water discharge destination map is for water discharge execution,
A code indicating non-execution of water discharge, for example, 1 and 0 is made to correspond to the washing place Karan AK, bath Karan BK, and shower head S, and is stored in a predetermined address of the backup RAM 44 secured as an area for determining the water discharge destination. It has been written. For example, if 1 is written as the code corresponding to the shower head S, the shower head S is determined as the water discharge destination. In addition, washing place Karan AK,
0 for all Bascaran BK and shower head S
If is written, it is determined that the water is not discharged from any of the water discharge destinations. The writing of this code is performed by pressing an instruction button such as a water discharge destination instruction button (not shown) on the operation panel P or a water instruction button on a water discharge temperature setting panel of each currant, or turning on / off the shower head S (not shown). Interrupt processing is performed when a button or the like is pressed. In addition, in the initial processing, a code of 0 (no water discharge is executed) is written for each water discharge destination.

Next, the set water discharge amount preset for the water discharge destination read in S100 is read from the water discharge amount map (S110). This water discharge amount map individually stores an appropriate water discharge amount (water discharge amount per unit time that is considered optimal for the user) corresponding to each of the water discharge destinations of the washing place Karan AK, bath Karan BK, and shower head S,
Similar to the water discharge destination map, it is written in a predetermined address of the backup RAM 44 secured as an area for determining the water discharge amount. For example, Karin AK
If it is 10 liters / minute, if Bascaran BK is 15 liters / minute, if it is a shower head S, it is 1
It is written and stored as 0 liters / minute.

That is, the water discharge destination and the water discharge amount are determined by performing the processing of S100 and S110. In addition,
The set water discharge amount for each water discharge port is written in advance at a predetermined address of the backup RAM 44 by a daily operation of a button (not shown) for setting the water discharge amount on the operation panel P or an operation at the time of construction of the water discharge device 1. Further, this writing is interrupted when the button is operated.

Then, it is judged whether the temperature of the discharged water is the proper hot water temperature (the temperature within the proper discharged water temperature range) or the temperature of water or hot water (S115). This judgment is made by the water instruction button 35a, the suitable hot water instruction button 35b, and the hot water instruction button 35c.
This is done based on the water discharge temperature flags (FW, FM, FH) that are set / reset in a water discharge temperature switching routine which will be described later and which is interrupted when each instruction button is pressed.

Here, if a negative decision is made, specifically, the water discharge temperature flag FW indicating that the water discharge temperature is the temperature of water.
Alternatively, if it is determined that the current water discharge temperature is the temperature of the water or the hot water based on the set state of the water discharge temperature flag FH indicating that the water discharge temperature is the temperature of the hot water, the merge flow path 23 is filled with the water or the hot water. Inflow may be done alone. Therefore, in S120, the drive amount of the actuator corresponding to each valve is set so that one of the flow rate adjusting valves 15 and 17 has the flow rate of zero and the other has the set water discharge amount read in S110. After that, the flow shifts to S165, which will be described later, to perform processing for determining whether or not to start water discharge.

If it is determined in S115 that the current water discharge temperature is the temperature of the suitable hot water based on the set state of the water discharge temperature flag FM indicating that the water discharge temperature is the temperature of the suitable hot water, it is read in S100. Regarding the water discharge destination, the preset water discharge temperature T0 preset within the above-mentioned proper water discharge temperature range (38 to 46 degrees) is read from the water discharge temperature map (S1).
30). This water discharge temperature map is one in which the water discharge temperature (an arbitrary temperature within the above-mentioned appropriate water discharge temperature range) is individually stored in correspondence with each water discharge destination of the washing facility Karan AK, bath Karan BK, and shower head S. Similar to the water discharge destination map and the water discharge amount map, it is written in a predetermined address of the backup RAM 44 secured as an area for determination.

That is, by performing the affirmative determination of S115 and the process of S130 subsequent to the processes of S100 and S110, the water discharge amount and the set water discharge temperature T0 within the appropriate water discharge temperature range are determined for each water discharge port. In addition, the set water discharge temperature T0 for each water discharge port is the temperature decrease instruction button and the temperature increase instruction button on the water discharge temperature setting panel of each currant (in the case of the washing room Karan AK, the temperature decrease instruction button 35h and the temperature increase instruction button 35i). In addition to the water discharge amount, it is written in advance in a predetermined address of the backup RAM 44 by a daily operation such as a button for changing the water discharge temperature on the operation panel P or an operation at the time of construction of the water discharge device 1. Note that this writing is interrupted when the corresponding button is operated, the details of which will be described later.

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 (S140). .. At this time, the confluent flow path 23
The control signal corresponding to the detected water discharge temperature is also output to the water discharge temperature switching panel of each currant unit to turn on the numerical value LED of the indicator lamp group corresponding to the detected water discharge temperature.

Next, based on the set water discharge amount and the set water discharge temperature T0 read in S110 and S130 and the detected values from the respective sensors read in S140, etc., the set water discharge temperature T0 is set.
The flow rates of water and hot water for discharging the mixed hot and cold water of (3) at the set water discharge amount are calculated (S150). Then, the flow rate adjustment amounts of the flow rate adjustment valves 15 and 17 corresponding to the calculated flow rates, that is, the actuator 19 and the actuator 21.
Drive amount is calculated (S160).

Then, it is determined whether or not the water discharge can be started (S165). This judgment is set and reset in the below-described spout temperature switching routine that is interrupted when the water instruction button, the appropriate hot water instruction button, and the hot water instruction button on each spout temperature setting panel are pressed. It is made based on the flag Fon.

If it is determined in S165 that the water spouting is not possible (water spouting disabled), the process proceeds to S100 described above, and the processing of the above steps is continued until it is determined that the water spouting can be started. .. On the other hand, if it is determined that the spouting can be started in S165, the mixed hot water or the water or hot water having the set spouting temperature T0 read in S130 is set in S100.
In order to discharge water from the water discharge destination read in step S110 with the water discharge amount read in step S110, the process proceeds to step S170.

That is, the drive amount calculated in S140 or S
A drive signal corresponding to the drive amount set in 120 is output to each actuator, and a drive signal (valve opening signal) is output to the solenoid valve of the water discharge switching unit 27 corresponding to the read water discharge destination (S170). At this time, the drive signal (valve closing signal) is sent to the solenoid valve corresponding to the water discharge destination other than the read water discharge destination.
Is output. That is, the solenoid valve is switch-controlled. Receiving this signal, each actuator is driven and each flow rate adjusting valve adjusts the flow rate. Therefore, the calculated flow rate of water and hot water flow into the merging flow path 23, and from the water discharge destination controlled to switch by the water discharge switching unit 27. , Mixed hot water having a set water discharge temperature T0, or water or hot water is discharged at a set water discharge amount.

After the water is discharged in this way, the process proceeds to S100 and the above-mentioned processing is repeated. Therefore, when the water discharge is started from the water discharge destination determined in S100, the water discharge is continued until the code of the water discharge destination map regarding this water discharge destination is set to 0.

Next, the discharge water temperature switching routine will be described. This water discharge temperature switching routine is performed by using each instruction button of the water discharge temperature setting panel for each currant (in the case of the water discharge temperature setting panel 35 of the washing place Karan AK, a water instruction button 35a,
When the appropriate hot water instruction button 35b and the hot water instruction button 35c are pressed, an interruption process is performed, and the water discharge temperature for each water discharge destination is switched. In the following description, the description will be omitted when the shower head S is the water discharge destination. This is because discharge of water from the shower head S is often performed through operation of an on-off button incorporated in the shower head S and a predetermined button of the operation panel P for switching the discharge water temperature. Because it can be distinguished from the water discharge from.

When the discharge water temperature switching routine is executed by pressing the respective instruction buttons, first, as shown in FIG.
The water discharge destination is determined depending on which curran the discharge water temperature setting panel to which the pressed instruction button belongs (S
200). If you want to spout water from the washing place Karan AK, each instruction button of the water discharge temperature setting panel 35 of the washing place Karan AK is operated, and if you want to sprinkle water from the bath Karan BK, each instruction button of the water discharge temperature setting panel 37 of the Bath Karan BK is operated. It is believed that

When the water discharge destination is determined in this way, the water discharge destination map relating to the determined water discharge destination is rewritten (S2).
10). For example, if one of the instruction buttons on the discharge water temperature setting panel 35 of the washing place Karan AK is operated and the washing place Karan AK is determined as the water discharge destination in S200, the spout execution code 1 is written to the washing place Karan AK of the discharge destination map. .. In this way, when the water discharge destination map is rewritten to discharge water at the washing place Karan AK, the washing place Karan AK is determined as the water discharge destination in S100 of the water discharge routine. Also,
If any of the instruction buttons on the water discharge temperature setting panel 35 of the Bascaran BK is operated, the Bascaran BK is determined as the water discharge destination through the rewriting of the water discharge map as described above.

Next, determination of the water discharge destination in S200, S21
It is instructed whether or not the instruction button operation for executing the rewriting of the water discharge destination map at 0 is the water instruction button operation on each of the water discharge temperature setting panels, that is, to perform the water discharge at the water temperature (water discharge). It is determined whether or not (S215). If a negative determination is made here, that is, if it is determined that the hot water discharge (hot water discharge) or the mixed hot water at a suitable hot water temperature (suitable hot water discharge) is performed, the process proceeds to S330 described below.

If it is determined in step S215 that the water discharge button is operated to discharge water, the water discharge temperature flags FW, FH, and FM indicating that the water discharge temperature is one of the water temperature, the appropriate hot water temperature, and the hot water temperature are displayed. Of these, the discharge water temperature flag FW has a value of 1
Is set, and the value 0 is set to FH and FM (S2
20). Accordingly, in S115 of the water discharge routine, it is determined that the temperature of the water discharge is the temperature of the water, and in S120, the actuator drive amount (flow rate adjustment valve 17 on the hot water side = flow rate =
Zero, water side flow rate adjusting valve 15 flow rate = set water discharge amount) is set.

Thereafter, it is determined whether the water discharge destination determined in S200 is the washing place Karan AK or the bath Karan BK (S225), and if it is determined to be the Bath Karan BK, the process proceeds to S300 described later. If it is determined in S225 that it is Karan AK, in addition to this determination, S200
Of the water discharge destination in step S210, rewriting of the water discharge destination map in step S210,
The washing place Karan water spouting flag which is set in a step described later to determine whether or not the current operation of the water instruction button 35a attached to the washing place Karan AK, which has sequentially executed the water discharge determination in S215. It is determined whether FAW1ST is 1 (S235). This washing place Karan water discharge flag FAW1ST is set in the next step S240, and the water instruction button 35 attached to the washing place Karan AK.
This indicates that the operation of a has been performed and this routine has been executed. Therefore, the water instruction button 3 attached to the washing room Karan AK
If the operation of 5a is the first operation, a negative determination is naturally made in S225 and the process proceeds to S240. In the following description of each process, the operation of each instruction button attached to each currant will be sequentially described.

Washing place Karan AK water instruction button 35 attached
If the operation of a is the first operation, the process proceeds to S240 after a negative determination in S235, sets the value 1 to the washing place currant water spouting flag FAW1ST, and other flags,
Washing place Karan hot water spouting flag FAM1ST, Washing place Karan hot water spouting flag FAH1ST, Bath currant water spouting flag FBW1ST
, A value 0 is set to each of the Bascaran hot water spouting flag FBM1ST and the Bascaran hot water spouting flag FBH1ST. In this way, it is recognized that the current operation of the water instruction button 35a attached to the washing place Karan AK is the first operation. It should be noted that each flag is set to an initial value of 0 in an unillustrated initial process when the power is turned on.

After that, the value 1 is set to the water discharge start flag Fon (S250), and this routine is once terminated. The water discharge start flag Fon is set based on the first operation of the water instruction button 35a attached to the washing place Karan AK.
Means that water discharge can be started from. Therefore, it is determined in S165 (FIG. 4) of the water discharge routine that water discharge can be started, and in S170, control of the flow rate adjustment valve based on the actuator drive amount set in S120 (flow rate adjustment valve 17 on the hot water side = zero flow rate). , The flow control valve 15 on the water side = flow rate = set water discharge amount) and the solenoid valve of the water discharge switching unit 27 corresponding to the washing place Karan AK is opened. As a result, when the operation of the water instruction button 35a attached to the washing place Karan AK is the first operation, the water discharge is started from the washing place Karan AK by the pressing operation.

On the other hand, when the water instruction button 35a attached to the washing place Karan AK is operated again after the last time,
S2 of this routine executed when the button was operated last time
Since the value 1 has been set in the washing place currant water discharge flag FAW1ST by the processing of 40, an affirmative decision is made in S235, and the flow shifts to S260. In this S260, it is determined that the water discharge from the washing place Karan AK is stopped and the water discharge start flag Fon
Set the value 0 to. In response to this, S in the water discharge routine
In 165 (FIG. 4), it is determined that water discharge is impossible.

After that, rewriting of the water discharge destination map (writing of code 0 of water discharge non-execution to the washing place Karan AK of the water discharge destination map) is executed (S270), and then the water discharge flags FAW1ST, FAM1ST, FAH1ST, FBW1ST, FBM
Set the value 0 to all flags of 1ST and FBH1ST (S
280). In this way, by setting the value of each water discharge flag to 0, regardless of whether the next operation of the instruction button is the water instruction button, the suitable hot water instruction button, or the hot water instruction button, the first button operation of the button is performed. Prepare for recognition.

Then, a return signal (valve closing signal) to the solenoid valve of the water discharge switching unit 27 corresponding to the actuator return signal and the washing place currant AK is output (S290), and this routine is once terminated. Therefore, when the water instruction button 35a attached to the washing place Karan AK is operated again subsequent to the previous time, the water discharge from the washing place Karan AK is immediately ended.

Next, a case will be described in which the water instruction button attached to the bath calan BK is pressed or the water instruction button attached to the bath currant BK is pressed first, following the operation of the water instruction button 35a attached to the washroom currant AK.

In this case, the water discharge destination is determined to be the Bascaran BK in S200, and the water discharge execution code 1 is written in the Bascaran BK of the water discharge destination map in S210. For this reason, the water discharge map, which was previously set as the water discharge execution code 1 for the washing place Karan AK, becomes the water discharge map in which the water discharge execution code 1 is written for the bath curran BK. Therefore, in S100 of the water discharge routine, the water discharge destination is changed from the washing place Karan AK to the bath Karan BK, so that the value 1 is set in the water discharge start flag Fon as will be sequentially described below, and the value from the bus Karan BK is changed from S165 (FIG. 4). If the start of water discharge is permitted, water discharge is started from the Bascaran BK.

Next, in S215, an affirmative decision is made and S220.
In step S225, a negative determination is made by the determination of the water discharge destination (baskallan BK) in step S200.
Then, the process proceeds to the next S300 shown in. In S220, similarly to the previous time, the discharge water temperature flag FW is set to a value of 1 and FH and FM are set to a value of 0, whereby the control of each flow rate adjusting valve performs water discharge. Become. However, at this S210, Bascaran B
Since water is discharged from K, the water flow rate adjustment valve 15
Is controlled to be the set water discharge amount from the Bascaran BK.

In S300, as shown in FIG. 6, as in the case of S235 (FIG. 5) described above, it is determined whether or not the operation of the water instruction button attached to the bass currant BK is the first operation.
Judgment is made based on the value of the Bascaran water discharge flag FBW1ST. Since the operation of this water designation button is the operation subsequent to the operation of the water instruction button 35a attached to the washing place Karan AK as described above, the value 0 is set to the bath currant water discharge flag FBW1ST in S240 or S280. There is. Alternatively, even if it is the first operation for the Bascaran BK, the Bascaran water discharge flag FBW1S is still used in the initial processing.
The value 0 is set in T. Therefore, a negative determination is made in S300, and the process proceeds to S310.

In this S310, the Bascaran water discharge flag FBW1ST is set to the value 1, and the other flags FAW1ST,
FAM1ST, FAH1ST, FBM1ST, and FBH1ST are set to a value of 0, and the current operation of the water instruction button attached to the Bascaran BK is different from that of the instruction button (the water instruction button 35a attached to the washroom currant AK). Recognize it as the first one.

Thereafter, the water discharge start flag Fon is set to the value 1 (S320), and this routine is once terminated. The water spouting start flag Fon in this case means that water spouting can be started from the bath currant BK based on the operation of the water instruction button attached to the bath currant BK. Therefore, it is determined in S165 (FIG. 4) of the water discharge routine that water discharge can be started, and in S170, control of the flow rate adjustment valve based on the actuator drive amount set in S120 (flow rate adjustment valve 17 on the hot water side = zero flow rate). , The flow control valve 15 on the water side = the set water discharge amount) and the solenoid valve of the water discharge switching unit 27 corresponding to the Baskeran BK is opened and the other solenoid valves are closed.

As a result, if the current operation of the water instruction button attached to the Bascaran BK is an operation subsequent to a different instruction button or the first one, the pressing operation starts water discharge from the Bascaran BK. At this time, by operating the water instruction button attached to Bascaran BK this time, the water spouting destination is set to Bascaran BK at 100 of the water spouting routine, and S1
At 70, the solenoid valve corresponding to the Bascaran BK is opened, and the water discharge destination is switched.

Next, the case where the water instruction button attached to the Bascaran BK is operated again following the previous time will be described. In this case, since the value 1 has been set for the Bascaran water discharge flag FBW1ST by the processing of S310 (FIG. 6) of this routine that was executed the last time the button was operated, an affirmative decision is made in S300, and S260
(Fig. 5). Then, since the respective processes of S260 to S290 are sequentially executed, it is determined in S165 (FIG. 4) of the water discharge routine that the water discharge is impossible, and the water discharge from the bass currant BK is completed, and the next operation of each instruction button is prepared.

Next, following the operation of the water instruction button 35a attached to the washing place Karan AK and the water instruction button attached to the bath Karan BK, the hot water instruction button 35c attached to the washing place Karan AK.
A case will be described where is pressed, or the hot water instruction button 35c attached to the washing place Karan AK is pressed first.

In this case, in S200 (FIG. 5), the water discharge destination is determined to be the washing place Karan AK, and in S210, the water discharge execution code 1 is written in the washing place Karan AK of the water discharge destination map. For this reason, if the water spout execution code 1 was previously applied to the bath currant BK, the water spout execution code 1 is written to the washing place currant AK. Therefore, in S100 of the water spouting routine, the water spouting destination is changed from the bath currant BK to the washing spot Karan AK, and thus the water spouting start is started from the washing spot Karan AK after the water spout start flag Fon is set to the value 1. Even if the water spouting destination is the washing place Karan AK as in the previous case, there is no problem due to the writing of the code.

Next, in S215, a negative determination is made based on the operation of the hot water instruction button, and the process proceeds to S330. This S3
In FIG. 30, as shown in FIG. 7, it is determined whether or not it is a hot water spouting instruction following the water spouting determination other than the water spouting in S215. In this case, therefore, the hot water instruction button 35c attached to the washing room currant AK is pressed. An affirmative judgment is made based on the operation, and then the process proceeds to S340 to prepare for execution of hot and cold water discharge.

That is, the discharge water temperature flag FH is set to the value 1 and the FW and FM are set to the value 0 (S34).
0), so that the water discharge temperature is determined to be the temperature of the hot water in S115 (FIG. 4) of the water discharge routine, and S120
Actuator drive amount (flow control valve 17 on the hot water side)
(Flow rate = set water discharge rate, water side flow rate adjustment valve 15 flow rate = zero) is set, and the control of each flow rate adjustment valve is to perform hot water discharge.

After that, in the processing from S345 to S370, the same processing as the above-mentioned S225 to S250 (FIG. 5) is performed. Therefore, based on the operation of the hot water instruction button 35c attached to the washing place Karan AK, it is determined that the water spouting destination is the washing place Karan AK (S345), and this operation of this button is the operation following the different button or the first operation. It is determined that there is (S355), and the subsequent S360
At the washing place Karan hot water spouting flag FAH1ST is set to a value of 1 and other flags FAW1ST, FAM1ST, FBW1ST, F
Set a value of 0 for each of BM1ST and FBH1ST and prepare for hot water spouting from Karan AK.

Then, the water discharge start flag Fon is set to the value 1 (S370), and this routine is once terminated. The water spouting start flag Fon in this case means that water spouting can be started from the washing place Karan AK based on the operation of the hot water instruction button attached to the washing place Karan AK. Therefore, in the water discharge routine, water discharge start determination in S165 (FIG. 4), control of the flow rate adjusting valve based on the actuator driving amount in S170 (flow rate adjusting valve 17 on the hot water side = set water discharge rate, flow rate adjusting valve on the water side 15 flow rate = Zero) and the solenoid valve of the water discharge switching unit 27 corresponding to the washing place Karan AK are opened, and the solenoid valves corresponding to the other water discharge ports that have been opened until then are closed.

As a result, if the current operation of the hot water instruction button 35c attached to the washing room currant AK is an operation subsequent to a different instruction button or the first one, hot water spouting is started from the washing room currant AK by the pressing operation.

Washing place Karan AK Hot water instruction button 35 attached
If c is operated again subsequently to the last time, S35
Since an affirmative decision is made in step 5 and the processing proceeds to the processing of S260 (FIG. 5) and subsequent steps, it is also judged in step S165 (FIG. 4) of the water spouting routine that water spouting is not possible, and the hot water spouting from the washing place Karan AK is completed and Prepare for the operation of each instruction button.

Further, when the hot water instruction button attached to the bath caran BK is pressed subsequently to the operation of a different instruction button or is pressed first, the bath caran B of the water discharge destination map.
Writing the code 1 for water discharge execution to K (S210,
5), negative determination of water spouting instruction (S215), S345
After the judgment of the water discharge destination = Vascaran in FIG. 8 and the like, the process proceeds to S380 shown in FIG. Therefore, even in this case, S38
In the processing from 0 to S400, the above-mentioned S235 to S2
Up to 50 (Fig. 5) or S355 to S370 (Fig. 7)
The same process is performed to prepare for hot water spouting from Bascaran BK. The difference is that in the process in S390, the value of 1 is set for the bath currant hot water discharge flag FBH1ST and the other flags FAW1ST, FAM1ST, FAH1ST, FBW1ST, FBM.
The point is to set the value 0 to each 1ST.

Then, if the current operation of the hot water instruction button attached to the Bascaran BK is an operation subsequent to a different instruction button or the first operation, the water discharge start flag Fon is set to a value of 1 in S400 and then the pressing operation is performed. As a result, hot water spouting is started from Bascaran BK.

Further, if the hot water instruction button attached to the Bascaran BK has been operated again subsequent to the last time, S380
An affirmative decision is made in step S260 (FIG. 5) and subsequent steps. Therefore, it is determined in S165 (FIG. 4) of the water spouting routine that the water spouting is impossible, and the hot water spouting from the bath caran BK ends, and the next operation of each instruction button is prepared.

On the other hand, washing place Karan AK or bath Karan B
When the appropriate hot water instruction button attached to each of the currants of K is pressed following the operation of a different instruction button or is pressed first, writing of the spouting execution code 1 to the washing place currant AK or the bath currant BK of the spout destination map ( S21
0, FIG. 5), negative judgment of water spouting instruction (S215), negative judgment of hot water spouting instruction (S330), and then S4 shown in FIG.
It shifts to 10 and prepares for execution of suitable hot water discharge.

That is, the discharge water temperature flag FM is set to the value 1 and the FW and FH are set to the value 0 (S4).
10), which causes S115 of the water discharge routine (FIG. 4).
At S1, it is determined that the temperature of the discharged water is the temperature of the suitable hot water, and S1
The actuator drive amount is calculated by the processing from 30 to S160, and each flow rate adjustment valve is controlled based on this drive amount. As a result, the mixed hot water (suitable hot water) having the set water discharge temperature T0 is discharged.

After that, in the processing from S415 to S440, the same processing as that from S225 to S250 (FIG. 5) described above is performed. Alternatively, S450 to S450 shown in FIG.
In the processing up to 470, the processing from S235 to S250 (FIG. 5) described above is performed. Therefore, if the current operation of the suitable hot water instruction button attached to each curran is an operation subsequent to a different button or the first operation, set the suitable hot water discharge flag FAM1ST or FBM1ST to a value of 1 and other flags in S430. The appropriate hot water spouting is started from each of the currants after the setting of 0.

Further, when the suitable hot water instruction button attached to each curran is operated again subsequent to the previous time, an affirmative decision is made in S425 or S450, and the processing shifts to the processing of S260 and thereafter. In FIG. 4), it is determined that water spouting is not possible, and the appropriate hot water spouting from each currant ends, and the next operation of each instruction button is prepared.

Next, a mixed hot water temperature changing routine for changing the water discharge temperature during the discharge of the mixed hot water will be described with reference to the flow chart shown in FIG. This water discharge temperature change routine is performed by the operation panel P in addition to the temperature decrease instruction buttons and the temperature increase instruction buttons (the temperature decrease instruction button 35h and the temperature increase instruction button 35i in the case of the washing place Karan AK) on the water discharge temperature setting panel for each currant. When a button or the like for changing the water discharge temperature is pressed, an interrupt process is performed, and the water discharge temperature at the time of water discharge suitable for water is changed within a predetermined range. In the following description, in order to simplify the description, the case where the temperature decrease instruction button 35h and the temperature increase instruction button 35i in the discharge water temperature setting panel 35 shown in FIG. 3 are operated will be described.

When the discharge water temperature changing routine is executed by pressing each of the instruction buttons, first, as shown in FIG. 11, the user first determines based on the number of times the temperature decrease instruction button 35h or the temperature increase instruction button 35i is operated. The desired change amount ΔT of the water discharge temperature is determined (S500). For example, if the temperature drop instruction button 35h is operated twice in succession, the user determines that he / she desires to spout water having a spout temperature that is 2 degrees lower than the set spout temperature T0. The change amount (1 degree) per pressing of the temperature decrease instruction button 35h or the temperature increase instruction button 35i is stored in the ROM 42 in advance.

Next, the set water discharge temperature T0 is read from the backup RAM 44 (S510), and the set water discharge temperature T0 is calculated from the set water discharge temperature T0 and the desired temperature change amount ΔT determined in S500 (S520). Then, it is judged whether or not the calculated set water discharge temperature T0 is within the proper water discharge temperature range (38 to 46 degrees) (S52).
5).

If it is determined that the calculated set water discharge temperature T0 is equal to or lower than the lower limit temperature of 38 degrees in the proper water discharge temperature range, this lower limit temperature 38 degree is set as the set water discharge temperature T0 (S540), and the calculated set water discharge temperature is set. If it is determined that T0 is equal to or higher than the upper limit temperature 46 degrees of the proper water discharge temperature range, this upper limit temperature 46 degrees is set as the set water discharge temperature T0 (S5
50). On the other hand, if the calculated water discharge temperature T0 is within the proper water discharge temperature range, no action is taken and the process proceeds to S550.

Then, in S550, the calculated set water discharge temperature T0 within the proper water discharge temperature range, 38 degrees set because the lower limit temperature of the proper water discharge temperature range is 38 degrees or less, and the upper limit temperature 46 of the proper water discharge temperature range. The set discharge water temperature T0 is updated as the set discharge water temperature T0 for the next time onward, and the set discharge water temperature T0 is updated as backup RA.
A new write is performed in M44 (S550), and this routine ends.

Thus, the set water discharge temperature T in the suitable hot water discharge
When 0 is updated and written, S1 in the water discharge routine
At 30 (FIG. 4), the updated set water discharge temperature T0 is read, and the flow rates of water and hot water are calculated so as to reach the read water discharge temperature (S150). Based on this, the flow rate adjusting valve 1
5. The flow rate adjusting valve 17 is controlled.

As described above, the water discharger 1 of this embodiment
Controls the flow rate adjusting valve 15 and the flow rate adjusting valve 17 so that when any one of the water instruction button, the appropriate hot water instruction button, and the hot water instruction button is pressed, the water discharge temperature is the discharge water temperature corresponding to the button. In other words, according to the water discharger 1 of the present embodiment, the discharge temperature can be set to the temperature of water, the temperature of hot water, or the predetermined temperature by simply operating the three buttons, that is, the water instruction button, the appropriate hot water instruction button, and the hot water instruction button. It is possible to discharge water at a predetermined suitable hot water temperature within the range, and it is possible to improve usability when switching the discharge water temperature.

Further, since the water discharge temperature when the suitable hot water instruction button is operated is changed within the predetermined temperature range, according to the water discharger 1 of this embodiment, the suitable hot water instruction button is operated. The water discharge temperature at this time can be various temperatures. As a result, the usability can be improved by diversifying the water discharge temperature.

Furthermore, by pressing each of the above-mentioned instruction buttons, in addition to switching the water discharge temperature, water discharge at the water discharge temperature can be performed quickly. Further, in stopping the water, the same button as the instruction button pressed to start the water discharge may be pressed, and in order to switch the water discharge temperature, an instruction button different from the previous time may be pressed. As a result, according to the water discharger 1 of the present embodiment, it is possible to improve usability without requiring a button operation only for turning on / off the water discharge or a large number of button operations for switching the water discharge temperature.

Besides, according to the water discharger 1 of the present embodiment,
The following effects can be achieved. In this example,
Each of the washing place Karan AK and the bath Karan BK was equipped with a discharge water temperature setting panel, and each panel was provided with the water instruction button, the appropriate hot water instruction button, and the hot water instruction button. And, of course, it is possible to switch the water discharge temperature by continuous operation of the same instruction button on the same panel and switch the discharge water temperature by continuous operation of different instruction buttons. The tip of the water can be changed to the spout to which the pushed instruction button belongs. Further, when different instruction buttons are continuously operated on different panels, the spouting destination is changed to the spout to which the pushed instruction button belongs, and the spouted water that the pushed instruction button instructs to spout from the changed spout It can be water spout of temperature. Specifically, while water is being spouted from the washing place Karan AK, if the water instruction button attached to the bath Karan BK is operated, the water discharge from the washing place Karan can be terminated and the water can be switched to water discharge from the bath Karan. Also,
While spitting water from the washing place Karan AK, by operating the appropriate hot water instruction button attached to the bath currant BK, it is possible to finish the spouting from the washing place currant and switch to the appropriate hot water discharge from the bath currant. Therefore, the usability can be further improved.

Further, since the temperature changeable range at the time of appropriate hot water spouting is limited, it is possible to avoid water spouting at a temperature far from the intended spouting temperature during the appropriate hot water spouting.
Therefore, it is possible to spout water at a temperature that suits the taste of the user. In addition, since the button for starting and ending the water discharge or switching the water discharge destination is not required, the configuration can be simplified.

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, the water discharger 1 of the present embodiment has been described as applied to the hot water supply system in the bathroom, but the invention is not limited to this and can be applied to a kitchen or the like. Further, although there is one suitable hot water instruction button, a configuration is provided in which a suitable hot water discharge temperature indicated by one suitable hot water instruction button and a suitable hot water discharge temperature indicated by another suitable hot water instruction button are different temperatures. It can also be a range. In this case, a suitable hot water instruction button that indicates the temperature range of the spouted water that is suitable for washing off oil stains adhering to the dishes, and an appropriate hot water instruction that indicates the temperature range of the spouted water that is suitable for washing off general stains. It is preferable to provide a button so that the water discharge temperature can be easily set according to the purpose of use. It is also possible to combine a single suitable hot water instruction button with a numeric keypad or the like so as to indicate a plurality of temperature ranges.
