Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water spouting device for spouting water in various water spouting modes from a water spout located at a position where an operator in a standing posture can spout water from above.

[0002]

2. Description of the Related Art A water discharge device of this type is used by being installed in a bathroom, a pool or the like, and has a plurality of shower heads on a wall surface. Each shower head includes a water discharge face plate having a different hole shape. For this reason, when each shower head is appropriately selected, the water discharge form thereof includes a water discharge form determined by a hole shape, for example, a water discharge form (straight) in which water is discharged in a straight shape, and a water discharge in which bubbles are included and water is discharged in a foam shape. The water is discharged in the form of a rod with a certain form (foam) or a certain amount of head difference.

To select the water discharge mode, one of the shower heads is selected by pressing a button for selecting the water discharge mode on the operation panel, and the hot water supply destination from the hot water source is switched to the selected shower head. In this way, it is possible to spout water in a plurality of water spouting forms, thereby diversifying the feeling of water spouting when spouting water and increasing the added value thereof.

[0004]

In general, the operation panel is provided at a position where it can be operated in a standing posture in consideration of the selection frequency of each water discharge form as described below. Since the straight water spouting form is selected when the spouting water is applied to the whole body, the selection frequency of the water spouting form is significantly higher than the selection frequency of other water spouting forms. That is, since the selection frequency of each water discharge form is extremely different, it is considered that the water discharge form having a high selection frequency can be easily selected.

However, even such a conventional water discharge device has the following problems.

[0006] In the water discharge form of pouring, even if the water is spouted in a rod shape, there is no need for poking unless there is a predetermined drop, for example, a drop of about 50 cm, to the part of the human body where the spout is bathed. Therefore, in order to take a shower while standing upright, the shower head must be installed at a high position. However, if the shower head is installed in this manner, the shower head must be removed by using a step or the like when the shower head is held by hand and spouted with water. If the shower head is placed at a position where it can be easily removed, in order to secure the above-mentioned head when bathing, it is inevitable that the shower head is in a sitting position.
Therefore, when taking a bath while already sitting in the washroom, it is difficult to operate the buttons on the operation panel while sitting, so stand up each time only to select the water discharge form of the bath and operate the buttons. I have to

The present invention has been made to solve the above problems, and it is an object of the present invention to improve the usability when executing water discharge from a water discharge port in various water discharge modes.

[0008]

In order to achieve the above object, the first means adopted by the present invention is a spout and a rod which are arranged at a position where an operator in a standing posture can spout water from above. A water spouting device having a water spouting means for spouting water from the water spout based on one of a plurality of water spouting forms including a spouting water spouting form A water discharge control operation unit which is provided at a position where the operation can be performed as it is, and which controls the water discharge executing means based on a water discharge mode selected from the plurality of modes,
A pouring form priority control operation unit which is provided at a position where the sitting posture can be operated, and which executes the control of the water spouting execution unit based on the spouting water spout form with priority over the water spouting control operation unit; It is the gist to provide.

A second means adopted in addition to this is to start with a water spouting port arranged at a position where an operator in a standing posture can spout water spouting from above, and a water spouting form for pouring a rod-shaped spouting water. A water spouting device having a water spouting execution unit that variably spouts water spouted from the spouting port based on a water spouting form of one of a plurality of forms, and an operation in a standing posture is possible A water spouting control operation unit which is provided at various positions, specifies a water spouting condition of a water spouting form and a water spouting amount of the plurality of forms, and controls the water spouting execution unit based on the specified water spouting condition; And a curran operation panel provided in the vicinity of the curran at a position where the spouted water from can be bathed, and having a temperature changing operation section for changing the temperature of the spouted water from the curran,
A curling operation priority instructing operation unit which is provided on the currant operation panel and gives an instruction to change the water discharging mode of the pouring to the water discharging mode from the spout, to give priority to the water discharging control operating unit to the water discharging executing unit; The operation of the temperature changing operation unit of the currant operation panel after the operation of the urging form priority instruction operating unit is converted into an operation of changing the water discharge amount at the time of water discharge in the water discharge form of the urging, and the conversion is performed. The gist of the present invention is to provide the water discharge amount priority control means for performing the control of the water discharge execution means based on the water discharge amount change operation with priority over the water discharge control operation part.

[0010]

In the water discharger adopting the above-mentioned first means, when the water discharge control operating portion provided at a position where the operation can be performed while standing upright is operated, the water discharge execution means is selected from among a plurality of modes. Control based on an arbitrary water discharge form. Therefore, the water discharge from the water discharge port is performed in an arbitrary water discharge mode among a plurality of modes.

On the other hand, when the urging form priority control operating portion provided at a position where the sitting posture can be operated is operated, control of the water discharge executing means based on the water discharge form of the urging is performed. Give priority to the club. Therefore, if you are in a sitting posture when operating this tilting mode priority control operation unit, operate the tilting mode priority control operation unit in that position,
The water spouting from the water spouting port can be performed in the form of pouring water. At this time, the distance between the operator in the sitting posture and the spout is set to a standing posture based on the fact that the spout is placed at a position where the operator in the standing posture can spout water from above. It is wider than the distance between an operator and the spout. As a result, the operator who operates the leaning mode priority control operation unit in the sitting posture, when taking the spouting water in the spouting waterfall form, is likely to take the spouting water in the waterfall spouting form with a head. Become.

The water discharger adopting the second means is
When the water discharge control operation unit provided at a position where the user can operate while standing upright is operated, the water discharge execution means for executing the water discharge from the water discharge port in a variable amount of water discharge is selected from among a plurality of forms specified. The control is performed based on a water discharge condition of an arbitrary water discharge form and water discharge amount. Therefore, the water discharge from the water discharge port is performed in an arbitrary water discharge form among a plurality of forms, and the amount of water discharge is also changed.

On the other hand, when the urging form priority control operation section provided at a position where the sitting position can be operated is operated, an instruction to change the urging water discharge form to the water discharge form from the water discharge port is discharged. The water discharge execution means is given priority over the control operation unit.
Further, when the temperature change operation unit of the currant operation panel is operated after the operation mode priority instruction operation unit is operated, when water is discharged in the water discharge mode of the operation by the pressure mode water discharge amount priority control means. It is converted into the change operation of the water discharge amount in. Then, the control of the water discharge execution means based on the converted water discharge amount changing operation is executed with priority over the water discharge control operation unit. As a result, if the user is in a sitting posture when operating the stilt form priority control operation unit, the stilt form priority control operation unit and the temperature changing operation unit on the currant operation panel are operated in the same posture to operate from the spout. The water is spouted in a flooded form, and the amount of water spouted is also changed.

At this time, due to the wide distance between the operator in the sitting posture and the spout, the operator in the sitting posture takes a spout of water in the pouring form. , You will be bathed in a spout of water with a head drop.

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

As shown in FIG. 5, a shower head S capable of switching four types of water discharge modes such as pouring is formed by securing a water discharge flow path 70 and a device storage space 71 other than this flow path. The shower head main body 72 and the cap 74 formed by opening the water discharge window 73 on the side surface are provided, and the cap 74 is watertightly assembled to the shower head main body 72. 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 shown in the figure. As shown by the arrow, the water discharge passage 70 of the shower head main body 72, the communication hole 8

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.

In the equipment storage space 71 of the shower head main body 72, in addition to the motor 77, an electronic control device (not shown) for driving and controlling the motor, and a rotation position of the rotary shaft 78 are detected to detect a water discharge window. A water discharge form detection sensor (not shown) for discriminating the water discharge nozzle facing the water discharge hole at 73 is housed.

An on-off button etc. for instructing to stop is arranged so that it can be pressed freely.

The electronic control device on the side of the shower head S is connected not only to the above-mentioned sensors and buttons, but also to the electronic control 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-
Start of water discharge from the shower head S by pressing the off button
When the stop is instructed, the electronic control device SS in the shower tower ST is passed through the electronic control device on the shower head S side.
A control signal is output to. 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. In addition, the singing designation button 57, the straight designation button 58, the foam designation button 59, the mist designation button 60 of the operation panel P attached to the shower tower ST.
When the water discharge form is selected by, a control signal is output to the electronic control device on the showerhead S side via the electronic control device SS. Upon receipt of this signal, the electronic controller on the side of the shower head S drives and controls the motor 77 to rotate the water discharge nozzle, and the water discharge nozzle corresponding to the selected water discharge mode causes the water discharge hole to face the water discharge window 73. Stop.

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

The flow chart of FIG. 6 shows the water discharge control (routine) which is the main control of the water discharge apparatus 1, and the flow chart of FIG. 7 shows the case when the discharge water temperature setting panel 35 of the washing place Karan AK is instructed. The spout water discharge control (routine) is shown. In addition, the flowchart of FIG. 8 shows the controlled discharge water amount change control (routine) that changes the discharged water amount from the washing place currant side AK during the execution of the casting.

The water discharge routine of FIG. 6 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. 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. Note that this code is written by pressing a button such as the bath currant instruction button 54 or the like on the operation panel P, a water button or the like on the discharge water temperature setting panel of each currant, or an on / off button or the like on the shower head S. Interrupted at the point when In addition, in the initial processing, a code of 0 (no water discharge is executed) is written for each water discharge destination.

Next, the water discharge amount and the water discharge temperature which are set in advance for the water discharge destination read in S100 are read from the backup RAM 44 (S110). The set water discharge amount and the set water discharge temperature are used for daily operations such as the temperature decrease instruction button 35h and the temperature increase instruction button 35i on the water discharge temperature setting panel 35 of the washing place Karan AK, as well as the water discharge temperature increase instruction button 62 on the operation panel P. Alternatively, it is written in advance at a predetermined address of the backup RAM 44 by an operation during construction of the water discharger 1. This writing is interrupted when the corresponding button is operated.

Following the reading of the water discharge destination, etc., the flow rate sensors 7 and 9 and the temperature sensors 11 and 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
A control signal corresponding to the detected water discharge temperature in is output to the operation panel P and the temperature is displayed. In addition, the output is also output to the discharge water temperature switching panel of each calan unit to turn on the LED of the numerical value of the indicator lamp group corresponding to the detected discharge water temperature.

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).

Then, it is judged whether or not the water discharge can be started (S145). The reason for making this determination is as follows. If the water spouting destination is each curran portion, there is no obstacle in starting the water spouting, and thus water may be spouted immediately, but if the water spouting destination is the shower head S, the rotary water spouting body 80 for changing the water spouting form is used. You must wait for the start of water discharge until the rotation is completed. Therefore, this S145
Then, the spout point determined in S100 is the washing place Karan AK,
If Bascaran BK, an affirmative decision is made unconditionally and S15
Move to 0. On the other hand, if the water spouting destination is the shower head S, it is determined in S145 whether or not the water spouting start is instructed in a later-described pouring water spouting routine or the like.

If it is determined in S145 that the water spouting is not possible, 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 in S145 that the water discharge can be started, from the water discharge destination read in S100 to S110.
In order to execute the water discharge of the water discharge amount and the water discharge temperature read in
A drive signal is output to each actuator, and a drive signal (ON signal) is output to the solenoid valve of the water discharge switching unit 27 corresponding to the read water discharge destination (S150). 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 merges with each other.
3, the hot water having the set water discharge amount and the set water discharge temperature is discharged from the water discharge destination controlled to be switched by the water discharge switching unit 27.

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. The writing of the code 0 to the water discharge destination map is executed by a routine (not shown) which is interrupted when the water button or the like on the water discharge temperature setting panel of each currant is successively operated twice. For example, an appropriate hot water button 35b on the discharge water temperature setting panel 35 of the washing place Karan AK
Is operated once and then this button is operated again, the code of the water discharge destination map relating to the washing place Karan AK is set to zero. The same applies to other water discharge destinations.

Next, the pouring water discharge routine will be described. This pouring water discharge routine is executed every time the pouring button 35k on the discharge water temperature setting panel 35 of the washing place Karan AK is pressed.

When the pouring water discharge routine is executed in this manner, as shown in FIG. 7, a pouring flag F1ST, which is set in a step described later, is used to determine whether or not the operation of the pouring button 35k is the first operation. It is determined whether or not it is 1 (S200). This song flag F1ST is the next S
It is to be set at 210, and the push button 35
This indicates that k has been operated and this routine has been executed. Therefore, if the operation of the song button 35k is the first operation, a negative determination is naturally made in S200 and S210 is performed.
Move to. In the explanation of each process below,
The operation of the broadcast button 35k will be described in order.

If the operation of the cast button 35k is the first one, the process proceeds to S210 after a negative determination in S200, and in this S210 the cast flag F1ST is set to the value 1 and the spout destination map is rewritten. To do. That is,
Code 1 is written in the shower head S of the water discharge destination map. In this way, the shower head S is designated as the water discharge destination from the water discharge temperature setting panel 35 side of the washing place Karan AK. It should be noted that an initial value of 0 is set to this flag F1ST in an initial process (not shown) when the power is turned on.

Next, it is determined whether the current water discharge form from the shower head S is a cast, straight, foam, or mist based on the detection signal from the water discharge form detection sensor (S220). After that, it is determined whether or not the determined current water discharge form is stagnation (S225).

Here, if it is determined that the current water discharge form is the stagnation, the process immediately proceeds to S240, and if it is determined that the current water discharge form is not the stagnation, a drive signal is output to the motor 77 ( (S230), the rotary water discharge body 80 is rotated. This drive signal is output until the water discharge nozzle 80b, which is in the form of a water discharge, causes the water discharge hole 82b to face the water discharge window 73. For example, in the case shown in FIG. 5, a drive signal for rotating the rotary water discharge body 80 by 180 degrees is output to the motor 77.

After that, after waiting for a rotation corresponding to the drive signal output from the motor 77, the casting start flag F
The value 1 is set to son (S240), and this routine is once terminated. The pouring start flag Fson means that the water discharge from the shower head S can be started. Therefore,
Since it is determined in S145 of the water spouting routine that the shower head S can start spouting water, the shower head S spouts water in a pouring water discharge form.

The processing from S220 to S230 is performed by the electronic control unit on the showerhead S side, and the following signals are exchanged between this electronic control unit and the electronic control unit SS on the shower tower ST side. Done. That is, after performing the process of S210 in the electronic control unit SS,
A control signal indicating that the determination of the current water discharge form is started is output to the electronic control device on the shower head S side. In response to this, the process of S220 is executed. When the rotation drive of the motor 77 performed by the electronic control device on the shower head S side is completed, a control signal to that effect is output from the electronic control device on the shower head S side to the electronic control device SS. In response to this, the above-described processing of 240 is executed.

On the other hand, when the casting button 35k is operated again subsequent to the previous one, the value 1 is set in the casting flag F1ST by this routine executed at the time of the previous manipulation of the button. Then, an affirmative decision is made and the routine proceeds to S250. In step S250, it is determined that the water discharge from the shower head S is stopped, and the casting start flag Fso is set.
Set the value 0 to n. Next, the value 0 is set in the casting flag F1ST, the water discharge destination map is rewritten (code 0 is written in the shower head S of the water discharge destination map) (S260), and this routine is ended. That is, the designation of the shower head S as the water discharge destination is canceled, and the water discharge from the shower head S (the water discharge form of the water drop) is completed by operating the water drop button 35k twice.

Next, a routine for changing the amount of spouted water will be described. This routine for changing the amount of spouted water discharge is executed every time the temperature decrease instruction button 35h or the temperature increase instruction button 35i on the water discharge temperature setting panel 35 of the washing place Karan AK is pressed.

When the pouring water discharge amount changing routine is executed in this way, as shown in FIG. 8, whether or not the pouring is being executed is determined by whether or not the value 1 is set in the pouring flag F1ST. (S300). This song flag F
1ST is set in the above-mentioned pouring water discharge routine, and the value 1 remains set while the pouring button 35k is continuously operated twice. Therefore, it is determined in S300 whether or not the pouring is being executed. To be judged.

If it is determined in step S300 that the casting is not executed, the pressed temperature decrease instruction button 35h,
The set water discharge temperature process, which is the original function of the temperature increase instruction button 35i, is performed (S310). That is, based on the number of times the temperature decrease instruction button 35h and the temperature increase instruction button 35i are operated, the set water discharge temperature is changed, for example, twice each.
The changed water discharge temperature is updated and written in a predetermined address of the backup RAM 44.

On the other hand, if it is determined in S300 that the casting is being performed, the casting is being performed, that is, the casting button 35.
The operation of the temperature decrease instruction button 35h and the temperature increase instruction button 35i after the k is first pressed is converted into a pouring water discharge amount changing operation by the following processing. That is, originally, the button operation for changing the water discharge temperature on the water discharge temperature setting panel 35 is converted into the operation for changing the pouring water discharge amount.

First, on the basis of the number of times the temperature decrease instruction button 35h or the temperature increase instruction button 35i is operated, the change amount ΔU of the discharge water discharge amount desired by the user is determined (S32).
0). For example, if the temperature decrease instruction button 35h is 2
If it is operated twice, the user can set the amount of water discharge U related to casting.
It is determined that the discharge amount of 2 liters less than 0 is desired. The amount of change (1 liter) per pressing number of the temperature decrease instruction button 35h or the temperature increase instruction button 35i.
Are stored in the ROM 42 in advance.

Next, the set water discharge amount U0 relating to the pouring is read from the backup RAM 44 (S330), the set water discharge amount U0 is updated from the set water discharge amount U0 and the desired change amount ΔU determined in S320, and the updated setting is made. Discharge amount U0
Is newly written in the backup RAM 44 (S34
0), this routine ends.

When the set water discharge amount U0 relating to the pouring is updated and written in this way, S110 in the water discharge routine.
At, the set water discharge amount U0 after updating is read, and the spouting water is executed with the read water discharge amount.

As described above, the water discharger 1 of this embodiment
