M404, RAM 406, and backup RAM 408 are mainly configured as a logical operation circuit, and input / output to / from the outside is performed by an input / output interface 412 interconnected with these via a common bus 410. That is,
The electronic control circuit 120 controls the hanger 30 of the water discharge head 100.
The motor 113 and the like are driven and controlled by the water discharge mode switching processing program stored in the ROM 404 so as to discharge water at a desired hot water temperature and water discharge mode according to the support position by 0 and 350 and the switch operation of the operation unit 130.

That is, when the motor 113 is driven by the command of the electronic control circuit 120 and the drive shaft 116 is driven to rotate via the reduction gear mechanism 114,
Rotates. At this time, the rotation position of the drive shaft 116 is controlled according to the signal of the potentiometer 118, and the water discharge inflow holes 172a to 172a of the water discharge form sections 170a to 170d are controlled.
One of the 2d is connected to the through hole 192. For example, FIG.
When the water discharge hole 174a shown in FIG. 2 faces the water discharge window 102, the hot water flowing out of the water discharge control device 10 passes through the flow path 180, the flow path 191, the through hole 192, the water discharge inflow hole 172 of the head main body D, and the water discharge hole. When the water reaches 174a, water is discharged in a straight water discharge form.

The switching process of the water discharge mode is shown in the flowcharts of FIGS. In FIG. 12, first,
Initialization processing is performed in step S200. As the initialization processing, processing such as setting the automatic change flag FAUT to 1 and fully closing the flow control valve 70 in the water discharge control device 10 is executed. In the following step S202, the current state of various switches and sensors is read, that is, the changeover switch 132, the mode changeover switch 13
4. Signals from the bathtub side reed switch 136, shower side reed switch 138, reed switch 139, etc. are read.

In the next step S210, the automatic change flag FAUT is determined. In this step S210, the automatic change flag FAUT is 0, and in step S21
If the mode change switch 134 is not operated in step S216, and even if the automatic change flag FAUT is set to 1 in step S210, if the mode change switch 134 is operated in step S216, After the automatic change flag FAUT is set to 0 in S218, the process proceeds to step S220. When the process proceeds to step S220, in the process up to step S226, switching of the water discharge mode in the manual mode or water stop is performed.

The processing in the manual mode will be described. First, if it is determined in step S220 that the changeover switch 132 has been operated, that is, if a command to switch the water discharge mode has been issued, the flow control valve 70 is closed in step S222, and then the flow proceeds to step S224. Then, in step S226, the motor 113 is rotated to change to the selected water discharge mode while watching the detection result of the potentiometer 118, and thereafter, the process returns to step 202. On the other hand, if it is determined in step S220 that the changeover switch 132 has not been switched, the process proceeds to step 228, in which the flow control valve 70 is opened to start water discharge, and then returns to step S202.

That is, when the switching of the water discharge mode is instructed by the operation of the changeover switch 132 in the processing from step S220 to step S226, the flow control valve 70 stops the water discharge to the water discharge head 150 side, and the rotary water discharge body is rotated. 160
After removing the water pressure applied to the motor to make it easier to rotate,
The water discharge body 160 is rotated to a predetermined position by 13 and then the flow control valve 70 is opened to start water discharge.

On the other hand, when it is determined in step S210 that the automatic change flag FAUT is 1 and the mode changeover switch 134 is not operated in step S216, and when the automatic change flag FAUT is set to 0 in step S210. If it is determined that the mode changeover switch 134 has been operated in step S212, the automatic change flag FAUT is set to 1 in step S214, and the process proceeds to step S240 and subsequent steps shown in FIG. Execute the water discharge mode.

Next, the processing in the automatic water discharge mode will be described. First, in step S240, it is determined whether or not the output SW1 of the bathtub side reed switch 136 is on. It is determined in step S240 that it is on, that is, the water discharging head 100 is
If it is determined that it is supported on the 00 side, the process proceeds to step S242, and it is determined whether the current water discharge mode is rectification. If it is determined in step S242 that the flow is not in the rectified water discharge mode, the process proceeds to step S244, and after closing the flow rate control valve 70, a signal is output to the motor 113 so as to be in the rectified water discharge mode (step S24).
6).

Then, after it is determined in step S242 that the water is in the rectified water discharge mode, in step S248,
A determination is made as to whether the reed switch 139 is on. If it is determined in this step S248 that it is on, that is, if it is determined that the hot water filling mode for the bathtub BT is selected, step S2 is performed.
At 50, the calculation of the total water discharge amount TM from the start of this step is started. This water discharge amount is calculated based on the time from the start of the first processing in step 250 and the output value from the pressure sensor 122. In the following step S252,
A determination is made as to whether the total water discharge amount TM has exceeded the total water discharge amount TM (for example, 200 liters). In the first process, a negative determination is made because it is equal to or less than the total water discharge amount TM, and the flow control valve 70 is fully opened in step S254, and the process returns to step S202 in FIG.

If it is determined in step S252 that the total water discharge amount TM is equal to or larger than TM in step S252, that is, if it is determined that the bathtub BT is filled with hot water, the process proceeds to step S256. After the flow control valve 70 is fully closed and the power is turned off in step S258, the present process is terminated.

On the other hand, if it is determined in step S240 that the output SW1 of the bathtub reed switch 136 is not on, the process proceeds to step S260 to determine whether the output SW2 of the shower reed switch 138 is on. Is executed. In step S260, when it is determined that the water is on, that is, when it is determined that the water discharge head 100 is supported by the shower-side hanger 350, the process proceeds to step S262, and whether the current water discharge mode is the shower is performed. Is determined. If it is determined in step S262 that the shower water discharge mode is not set, the process proceeds to step S264, and after closing the flow rate control valve 70, a signal is output to the motor 113 so as to be in the shower water discharge mode position (step S266). . Then, step S26
When it is determined in 2 that the mode has been switched to the rectified water discharge mode, the flow control valve 70 is opened (step S244), and water is discharged in the shower water discharge mode.

In the above embodiment, when the water discharge head 100 is supported by the bathtub hanger 300, a detection signal is output from the bathtub reed switch 136, and the rectified water discharge mode is selected based on the detection result. Water is discharged in the total amount TM, and the bathtub BT becomes full. Therefore, if the water spouting head 100 is supported by the bathtub hanger 300 and spouting is started, the automatic spouting flag FAUT is turned on in the initial state, so that the bathtub BT becomes full without any troublesome operation. can do.

In the water discharge device 1, instead of providing a part of the switch operation part for controlling the water discharge form in the operation part 331 of the water discharge head 100, the hanger 300 on the bathtub side is used.
Is provided as a switch mechanism 330, and the bathtub BT is filled with hot water by operating the switch mechanism. Therefore, even if various controls of the water discharge form of the water discharge head 100 are added, the number of operation buttons on the operation unit 331 does not increase. Therefore, there is no operation error or troublesome operation due to an increase in the number of operation buttons.

In addition, since the number of operating portions is not increased on the outer peripheral portion of the water discharge head, there is an effect that sealing performance is improved. In addition, since the switch mechanism in the bathtub-side hanger 300 does not have an electric circuit, there is no fear of electric leakage or the like.

Further, in the above embodiment, a switch for controlling the total amount of water discharged to the bathtub BT is provided as a switch mechanism. Since this switch mechanism is provided around the bathtub BT, the operability is excellent.

When the water discharge head 100 is supported by the shower hanger 350, the shower water discharge mode is selected. Therefore, when the water discharge head 100 is supported, the most frequently used water discharge mode is automatically selected, and the troublesome switching operation of the water discharge mode is not required, and the operability is improved.

Next, the switch mechanism 3 of the hanger on the bathtub side
Another embodiment of 30A will be described. FIG. 14 and FIG.
5, the switch mechanism 330A is different from the switch mechanism 330 of FIG. 9 in that a mirror 441 is provided instead of the permanent magnet 334, and a photocoupler 442 composed of a light emitting element and a light receiving element is used instead of the reed switch 139. And a water discharge head 10 corresponding to a path K therebetween.
That is, the case 101 part of No. 0 is formed in a transparent body.

In the state shown in FIG. 14, the light emitted from the light emitting element 442a of the photocoupler 442 is not incident on the light receiving element 442b even if it is reflected by the mirror 441, so that the switch is off. When the switch body 332 is pushed from this off state to the position shown in FIG. 15, the path K of light from the light emitting element 442a changes, and the light receiving element 44
2b is received. Therefore, the switch is turned on. That is, by moving the switch body 332 forward and backward, the mirror 441 performs switching operation by making light from the light emitting element 442a incident on the light receiving element 442b or not.

The present invention is not limited to the above-described embodiment, but can be implemented in various modes without departing from the gist of the present invention. For example, the following modifications are possible.

(1) The switch mechanism provided with the water discharge head on the hanger is not limited to the embodiment of FIG. 9 or FIG.
Various sensors such as a limit switch and a piezoelectric sensor can be used as long as the sensor operates in cooperation with the water discharging head.

(2) In the above embodiment, an example was described in which one switch mechanism was provided on the hanger. However, the present invention is not limited to this.
One hanger may be provided with a plurality of switch mechanisms, or a plurality of hangers may be provided with a switch mechanism for instructing the same or different functions of water discharge.

(3) In the above embodiment, the configuration applied to the water spouting head for the bathroom was described. However, if the spouting head is suitable for changing the water spouting form, the water spouting head in the kitchen or the water sprinkling in the garden can be used. It can be applied to various water discharge heads such as a water discharge head for use. For example, when the present invention is applied to a water discharge head in a sink unit, it is possible to adopt a configuration in which hangers are provided in close proximity to each of the cleaning tanks having different depths, and the water discharge mode is changed according to the position of the hanger. it can.

(4) In the above embodiment, the water discharge mode is switched and the total water discharge amount is set by the command of the switch mechanism provided on the hanger. In addition to this, the temperature of the discharged water and the temperature per unit time are determined. Control for changing the water discharge flow rate or the like may be appropriately added, and in this case, usability can be further improved.
