A speaker (sound output unit) 312 that outputs a warning sound, a predetermined announcement, and the like.

  The first operation device 3a is installed in a space where the shower device 7 is located. The first operation device 3a is configured as, for example, a bath remote controller, and is provided in a bathroom provided with the shower fixture 7. The first operation device 3a includes, as input operation units, a non-contact input operation unit 33 that performs an input operation by non-contact and a contact input operation unit 34 that performs an input operation (such as a general button input operation) by a pressing operation. . The second operation device 3b is configured as, for example, a kitchen remote controller, and is installed outside the space where the first operation device 3a is located. The second operating device 3b is installed, for example, near the mixing faucet of the sink outside the bathroom, which is another device 8. The second operation device 3b includes a contact input operation unit 34.

  As the communication line 5, for example, a two-core communication line capable of superimposing communication information on a power supply line is used. Information exchanged between the water heater main body 2 (control device 4) and each of the operating devices 3a and 3b includes command data relating to hot water supply (on / off of the hot water supply device, change of hot water supply set temperature, etc.), and notification data of hot water supply results ( Notification of reaching the bath set temperature, abnormal notification, etc.).

  The contact input operation unit 34 includes a plurality of operation buttons and a control unit 38. The control unit 38 includes a microcontroller, a memory, and the like. When any one of the plurality of operation buttons is pressed, the control unit 38 generates an operation command signal corresponding to the pressed operation button. The generated operation command signal is sent to control device 4 via communication units 32 and 6, and control device 4 controls water heater 1 (for example, water heater main body 2) based on the received operation command signal. .

  The touch input operation section 34 of the first operation device 3a includes a temperature increase button 41, a temperature decrease button 42, and a priority button 43. The touch input operation section 34 of the second operation device 3b includes a temperature increase button 41 and a temperature decrease button 42. When the temperature increase button 41 is pressed, the control unit 38 raises the set value of the temperature (hot water temperature) of the hot water supplied from the water heater body 2 in accordance with the number of times or the time of the pressing operation, and lowers the temperature. When the button 42 is pressed, the set value of the hot water supply temperature is reduced according to the number of times or the time of the pressing operation.

  The temperature increase button 41, the temperature decrease button 42, and the control unit 38 in the first operation device 3a function as a first hot water supply temperature input operation unit 40a for setting and inputting the hot water supply temperature. Further, the temperature increase button 41, the temperature decrease button 42, and the control unit 38 in the second operation device 3b function as a second hot water supply temperature input operation unit 40b for setting and inputting the hot water supply temperature.

  When the priority button 43 is pressed down, the control unit 38 sets the hot water supply temperature set and input by the first hot water supply temperature input operation unit 40a of the first operation device 3a to the second hot water supply temperature input operation unit of the second operation device 3b. A bathroom priority state is set, which is preferentially set for the hot water supply temperature set and input in 40b. That is, the priority button 43 and the control unit 38 constitute a bathroom priority input operation unit for switching whether or not the bathroom is in the bathroom priority state.

  When the priority button 43 is pressed down on the first operation device 3a, the control unit 38 notifies the notification unit 31b of the second operation device 3b that the bathroom priority state has been set. For example, a predetermined display (in this example, a character display 314 of “bathroom priority”) is lit on the display 311 of the second operating device 3b. Instead of this, a predetermined lamp may be turned on, or a predetermined notification sound (such as voice guidance indicating that the bathroom is in the priority state) may be output from the speaker 312.

  Further, each of the operation devices 3a and 3b has a contact input operation unit 34 as an operation on / off button of the water heater 1, a call button for talking with another operation device, and a recall button for performing a reheating operation of a bath. , And an automatic bath button for performing an automatic bath filling operation of a bath.

  The non-contact input operation unit 33 executes image recognition processing of an object (for example, a user's hand) from the first operation device 3a, and performs a predetermined input operation mode based on the result of the image recognition processing. An operation detection unit 36 that determines whether or not the operation has been performed is provided. The object to be detected is not limited to the hand of the user, and may be, for example, the arm or the whole body of the user. Further, image recognition may be performed using a body other than the user's body (for example, a predetermined object such as a bath article).

  The operation detection unit 36 includes an image sensor 39 and a control unit 38. The image sensor 39 includes, for example, a CCD image sensor / camera, a CMOS image sensor / camera, and the like. The control unit 38 determines whether a predetermined input operation has been performed based on the image captured by the image sensor 39. When it is determined that the predetermined input operation has been performed, the control unit 38 generates a corresponding operation command signal. Accordingly, the operation detection unit 36 can recognize that the gesture operation has been performed by performing a predetermined gesture operation while the user holds the hand over the first operation device 3a. Since the image sensor 39 is used in a private space such as a bathroom, a low-resolution image sensor that can determine whether a predetermined gesture operation has been performed is preferably used.

  As shown in FIG. 1, in the present embodiment, the control unit 38 is included in both components of the non-contact input operation unit 33 and the contact input operation unit 34 (configured as a common control unit). However, instead of this, the non-contact input operation unit 33 and the contact input operation unit 34 may be provided with individual control units. Further, the control unit 38 performs various processes based on signals received from other devices.

  In the present embodiment, the predetermined gesture operation that can be determined by the operation detection unit 36 includes a hot water amount changing operation of changing the hot water amount (water flow rate) of the shower fixture 7. For example, the predetermined gesture operation for the operation of changing the amount of hot water may be an operation of waving the hand left and right. The predetermined gesture operation for the hot water amount changing operation may be a gesture without movement such as turning a fingertip in any direction instead of such a gesture with movement. In addition, the predetermined gesture operation that can be determined by the operation detection unit 36 may include an operation of swinging the shower head of the shower fixture 7 in a specific direction, for example, as described in Japanese Patent Application Laid-Open No. 2011-250918. .

  It is difficult to use a manual faucet in a configuration for changing the amount of hot water of the shower fixture 7 based on such a gesture operation for changing the amount of hot water. Therefore, in the present embodiment, the water amount adjusting valve 236 is used as a hot water amount changing device for changing the hot water amount to be discharged from the water heater main body 2. That is, the control device 4 controls the water flow adjusting valve 236 based on the gesture operation for the hot water amount changing operation to change the amount of hot water discharged from the hot water supply outlet 234 of the water heater main body 2. With such hot water amount change control, the amount of hot water to be discharged from the shower fixture 7 is changed.

  The control for changing the amount of hot water of the shower fixture 7 includes control of stopping the hot water supply from the water heater main body 2. In the hot water supply stop control, the control device 4 controls the water flow control valve 236 so that the hot water flow from the hot water supply outlet 234 becomes the minimum water flow (about 0). In addition, the hot water amount change control of the shower fixture 7 may include a control other than the hot water stop control, such as a control for decreasing the hot water amount or a control for increasing the hot water amount, for example. , A plurality of gesture operations corresponding to each control are set. For example, a plurality of gesture operations correspond to tapping stop control, the operation of waving the hand to the left and right, the tapping amount reduction control, the operation of swinging the hand upward from below, and the tapping amount increase control. This may include an operation of waving a hand downward from above.

  In the present embodiment, the generation of an operation command signal based on a predetermined gesture operation is permitted when the pressing operation of the priority button 43 is triggered. That is, when the operation detection unit 36 recognizes a predetermined gesture operation in the bathroom priority state, operation control corresponding thereto is performed. As described above, in the present embodiment, the bathroom priority input operation unit including the priority button 43 and the control unit 38 controls the operation such as the hot water amount change control of the shower fixture 7 based on the gesture operation for the hot water change operation or the like. Function as a permission input operation unit for permitting the user.

  Note that, in the present embodiment, when the priority button 43 is pressed to enter the bathroom priority state, the notification unit 31a of the first operation device 3a notifies that the gesture operation has been enabled. For example, as shown in FIG. 2A, a predetermined display (in this example, a character display 313 of “OK”) is turned on when the display 311 of the first operation device 3a is in the bathroom priority state. It is composed of Instead, a predetermined lamp may be turned on, or a predetermined notification sound (including a voice message, a melody, a beep sound, etc.) may be output from the speaker 312. Note that such a notification mode is not an essential configuration.

  When the control device 4 detects the operation of changing the amount of hot water in a state in which the control for changing the amount of hot water of the shower fixture 7 is permitted by the pressing operation of the priority button 43 configuring the permission input operation unit (the bathroom priority state). By controlling the water amount adjusting valve 236, which is a hot water amount changing device, the hot water amount of the water heater main body 2 is changed.

  Further, control device 4 controls so that notification unit 31b of second operating device 3b notifies that the amount of hot water from hot water supply unit 2 has been changed. For example, as shown in FIG. 2B, the display 311 of the second operating device 3b displays a predetermined display (in this example, “stopping hot water!” In this example) when the water amount change control by the water amount adjustment valve 236 is executed. Is configured to light up. Instead, a predetermined lamp may be turned on, or a predetermined notification sound (including a voice message, a melody, a beep sound, etc.) may be output from the speaker 312.

  According to the above configuration, the user operates the permission input operation unit (priority button 43) on the first operating device 3a installed in the space where the shower equipment 7 is located, and the hot water amount change control of the shower equipment 7 is permitted. When the operation detecting unit 36 detects the operation of changing the amount of hot water by the user in a state where the hot water is supplied, the hot water amount changer (water amount adjusting valve 236) for changing the hot water amount of the hot water heater main body 2 is controlled. The amount of hot water is changed. At this time, the notification unit (the notification unit 31b of the second operation device 3b in this example) installed outside the space where the first operation device 3a is located is notified that the hot water supply amount of the water heater main body 2 has been changed. Therefore, even when the amount of hot water of the hot water heater main body 2 is changed in order to change the amount of hot water of the shower device 7, the hot water is used by another device (other tapping device 8) different from the shower device 7. The user can be notified without delay of the reason why the amount of hot water has changed.

  Further, by adopting the gesture operation as the hot water amount changing operation, the hot water amount of the shower fixture 7 can be changed by a simple operation. Accordingly, it is possible to reduce the necessity of the user's visual confirmation for changing the amount of hot water of the shower fixture 7 or the amount of operation of the user for changing the amount of hot water such as twisting the manual faucet.

  Further, since the amount of hot water is changed by the water amount adjusting valve 236, the hot water of the shower fixture 7 can be stopped without using a manual faucet.

  Further, in the present embodiment, the bath priority change operation of pressing down the priority button 43 permits the hot water amount change control of the shower fixture 7 by the hot water amount change operation. Therefore, by making the operation for starting the hot water amount changing operation common to the bathroom priority operation, the complexity of the operation by the user using the shower fixture 7 can be reduced.

  Further, as described above, in the bathroom priority state, the second operating device 3b is notified that the bathroom is in the bathroom priority state. Therefore, by this notification, before the hot water supply amount of the water heater main body 2 is actually changed, a user who uses hot water with a device different from the shower device 7 or a user who wants to use the hot water is provided with the hot water amount. Be alerted to the possibility of change.

  Further, by configuring the first operating device 3a including the operation detecting unit 36 for determining the hot water amount changing operation by the gesture operation as a bathroom remote controller, it is possible to prevent the system configuration from becoming complicated (separate operation detecting unit 36). Need to be provided). Similarly, by configuring the second operating device 3b having the notification unit for notifying that the amount of hot water from the water heater main body 2 has been changed by the water amount adjusting valve 236 as a kitchen remote controller, the system configuration becomes complicated. Can be prevented (the need to provide a separate notification unit is eliminated).

  As described above, the embodiments of the present invention have been described, but the present invention is not limited to the above embodiments, and various improvements, changes, and modifications can be made without departing from the gist of the present invention.

  For example, in the above-described embodiment, the mode in which the operation detection unit 36 performs image recognition has been described. However, the operation detection unit 36 only captures and stores an image, and the control device 4 executes a predetermined input operation mode. It may be determined whether or not.

  Further, in the above-described embodiment, the mode in which the operation detection unit 36 detects the gesture motion based on the image recognition is illustrated, but the present invention is not limited to this, as long as the gesture motion can be detected. Further, the operation detection unit 36 may be configured to detect a predetermined sound instead of detecting the gesture operation. In a configuration in which a touch input operation unit is provided on the surface of the first operation device 3a, the operation detection unit 36 may be configured to detect a touch operation on the touch input operation unit. As described above, the operation detection unit 36 may be configured as the non-contact input operation unit 33 or may be configured as the contact input operation unit 34 as exemplified in the above embodiment.

  In the above-described embodiment, hot water supply apparatus 1 includes a first operating device 3a including operation detecting unit 36 and a notification unit that notifies that the amount of hot water from water heater main unit 2 has been changed by water amount adjustment valve 236. Although the system configuration in which the second operation devices 3b are provided one by one has been described, the invention is not limited to this. For example, a plurality of first operating devices 3a may be provided, and a plurality of second operating devices 3b may be provided.

  Further, in the above-described embodiment, the mode in which the amount of hot water from hot water heater main body 2 is changed by adjusting water amount adjusting valve 236 as a hot water amount changer in the hot water amount change control, but the control object is not limited to this. I can't. For example, in a configuration in which an open / close valve is provided in the hot water supply path to the hot water supply outlet 234 of the water heater main body 2, the control device 4 controls (opens / closes) the open / close valve as a hot water supply amount changer based on a gesture operation or the like. Thus, hot water supply or stop to the shower equipment 7 may be controlled.

  Further, in the above-described embodiment, the mode in which the hot water amount change control based on the hot water amount change operation (gesture operation) is permitted by pressing down the priority button 43 has been described. That is, in the above embodiment, the priority button 43 also functions as the permission input operation unit. Instead, a permission input operation unit may be provided separately from the priority button 43. In other words, a mode in which the hot water amount change control based on the hot water amount change operation is permitted regardless of whether or not the bathroom is in the bathroom priority state may be adopted.

  Further, in the above-described embodiment, it has been described that the second operating device 3b is notified that the bathroom is in the bathroom priority state, thereby notifying that the hot water supply amount of the water heater main body 2 may be changed. However, in addition to the notification of the bathroom priority state (such as the character display 314 of “bathroom priority”), it may be notified that the amount of hot water from the water heater main body 2 may be changed. For example, the display 311 of the second operating device 3b may light up a character display such as "Caution! In particular, it is useful in a mode in which the hot water amount change control based on the hot water amount change operation is permitted regardless of whether or not the bathroom is in the bathroom priority state. However, there is no need to be informed that there is a possibility that the amount of hot water from the water heater body 2 may be changed in the second operating device 3b.

  Further, in the above-described embodiment, an example has been described in which the first operating device 3a is configured as a bath remote controller (a configuration including the first hot water supply temperature input operation unit 40a), but the first hot water supply temperature input operation unit 40a is used. The first operation device 3a may be configured separately from the bath remote control provided with. Similarly, in the above-described embodiment, a notification unit that is installed at a location different from the first operating device 3a and that notifies that the amount of hot water from the water heater main body 2 has been changed is a second hot water supply temperature input operation unit. Although the example in which the second operation device 3b (the kitchen remote controller) including the 40b is configured is shown, a notification unit may be configured separately from the second operation device 3b.

  The hot water supply device of the present invention is useful for notifying a user who uses hot water in a place other than a shower device of the reason why the amount of hot water has changed without delay.
