  The input setting operation means 52 is a means for performing an input operation of a target range of the flow rate of shower hot water supplied from the water heater 27 to the shower at the hot water supply destination and hot water supplied from the shower. In the present embodiment, the selection switch 29 of the bath remote controller 1 is configured to switch the setting range input operation mode of the shower hot water flow rate in addition to switching each setting mode such as the hot water temperature. The user selects the target range input operation mode with the selection switch 29, and confirms on the display screen 32 while pressing the setting switches 28a and 28b, thereby performing the input operation of the target range of the shower hot water flow rate.

  For example, in the target range input operation mode, first, an item for setting the lower limit value of the target range appears on the display screen 32. At this time, each time the setting switch 28b is pressed, the flow rate is increased by 1 liter / minute, and every time the setting switch 28a is pressed, the flow rate is decreased by 1 liter / minute. Then, after the user determines the desired flow rate as the lower limit value of the target range and then presses the selection switch 29, an item for setting the upper limit value of the target range appears on the display screen 32 next. At this time, setting of the upper limit value of the target range is performed by the setting switches 28b and 28a in the same manner as the operation of setting the lower limit value of the target range. When the selection switch 29 is pressed again, the setting of the target range is completed. To do.

  Note that the target range setting operation method is not limited to such a method, and is appropriately set. Moreover, it is good also as an aspect which can input the initial value of a target range into the bath remote control apparatus 1 previously, and can change the value according to liking by the said input setting operation | movement, for example. The value of the target range is not particularly limited and can be set as appropriate. Examples include a value of 6 to 12 liters / minute.

  The flow rate range setting unit 54 sets a set flow rate range adjacent to the target range using a value larger than the maximum value of the target range of the shower hot water flow rate. In this embodiment, the input setting operation unit The set flow rate range is set by the operation of 52, and this set value is added to the comparison / determination unit 53 via the flow rate range setting means 54. The setting operation method of the set flow range is not particularly limited, but in the present embodiment, the set flow range input operation mode can be selected by the selection switch 29, and the target range input operation is performed. Similar to the target range setting in the mode, it is performed by checking on the display screen 32 while pressing the setting switches 28a and 28b.

  In addition, regarding the setting of the set flow rate range, an initial value of the set flow rate range may be input to the bath remote controller 1 in advance, and the value may be changed by the user according to preference, for example, by the input setting operation. . Further, the value of the set flow rate range is not particularly limited and is set as appropriate, and examples thereof include a value of 12 to 15 liters / minute.

  Further, the bath remote controller 1 is provided with an automatic setting unit for the set flow rate range, and instead of setting the set flow rate range by the operation of the input setting operation unit 52 as described above, the operation of the input setting operation unit 52 is performed as described above. When the target range is input and set, the set flow rate range may be automatically set in a region that is larger than the maximum value of the target range and is adjacent to the target range.

  The comparison / determination unit 53 takes in the instantaneous value of the shower hot water use flow rate detected by the shower use instantaneous value detection means 51 at a predetermined set time (for example, 10 seconds), and uses the instantaneous value as the input setting operation. The target range set in advance by the operation of the means 52 and the set flow range set in advance by the flow rate range setting means 54 are compared. When it is determined that the instantaneous value is within the target range, a target achievement signal of the shower hot water use flow rate is output, and when the instantaneous value is determined to be within the set flow range, the instantaneous value is output. An identification signal for identifying that is within the set flow rate range is output. These signals are applied to the energy saving use notification means 58.

  When the target achievement signal is output from the comparison / determination unit 53, the energy-saving usage notification unit 58 notifies that the shower hot-water supply usage flow rate is the energy-saving usage amount by at least one of display and sound. In addition, when the identification signal is output from the comparison determination unit 53, the energy saving use notifying unit 58 displays that the shower hot water use amount is a value close to the energy saving use amount in correspondence with the identification signal. Notification is given by at least one of audio outputs.

  In the present embodiment example, the energy saving use notification unit 58 includes an eco mark display control unit 55. When the eco mark display control unit 55 outputs a target achievement signal from the comparison determination unit 53, FIG. As shown in the figure, an eco mark 40 indicating that the shower hot water use flow rate is an energy saving use amount is displayed on the lower right part of the display screen 32. When the output of the target achievement signal is stopped, the eco mark 40 is displayed. To stop.

  The eco mark 40 is not particularly limited, but is preferably a mark that is easy to understand at a glance, for example, as shown in FIGS. In this embodiment, the display screen 32 has a color display function, the eco mark 40 is green, and the eco mark 40 is lit.

  Further, the energy saving use notification means 58 has an eco approach display control means 56, and when the identification signal is output from the comparison judgment unit 53, the shower hot water use amount is changed to the energy saving use amount corresponding to the identification signal. Eco approach display for identifying and displaying that the values are close (in this embodiment, display of the eco approach mark) is performed on the display screen 32, and when the output of the identification signal is stopped, the display of the eco approach mark is stopped. To do.

  The eco approaching mark is not particularly limited, but it is preferable that the eco approaching mark be an easily understandable mark at a glance, like the eco mark 40. In this embodiment, the color of the eco approaching mark is yellow and distinguished from the eco mark 40, and the display of the eco approaching mark is blinking. Further, the eco approach display may be performed by a display such as a character display other than the eco approach mark.

  Furthermore, the energy saving use notification means 58 has a sound output control means 57, and when the target achievement signal is output from the comparison judgment unit 53, the sound output control means 57 indicates that the flow rate of shower hot water supply is the amount of energy saving use. For example, a voice guidance “eco-driving” is output from the speaker 34. In addition, when the identification signal is output from the comparison judgment unit 53, it is expressed in correspondence with the identification signal that the shower hot water usage is close to the energy saving usage. Such voice guidance is output from the speaker 34.

  In the present embodiment, the energy saving use notification means 58 includes a notification operation that the shower hot water use flow rate is an energy saving use amount and a notification operation that the shower hot water use flow rate is a value close to the energy saving use amount. Instead of performing switching immediately after the output of the goal achievement signal or identification signal output from the comparison / determination unit 53, the switching is performed when the number of continuous outputs of these signals reaches a preset value for each signal.

  For example, due to the relationship between the supply water pressure, etc., even if the shower hot water use flow rate becomes slightly larger than the value within the target range and becomes a value within the set flow rate range, the shower hot water use flow rate decreases immediately. The value may be within the target range. Conversely, the shower hot water use flow rate may become a value within the set flow rate range immediately after the value within the set flow rate range becomes a value within the target range. In such a case, switching between the display of the eco-mark 40 and the display of the eco-approaching mark and the switching of the voice guidance output are made to correspond to the goal achievement signal and the identification signal output from the comparison determination unit 53, and these signals are displayed. If it is performed immediately after the output, the switching is frequently performed, and it becomes difficult to see the display screen 32 of the bath remote controller 1 or the user feels the voice guidance output loud.

  Therefore, in the present embodiment, the reference number of times for switching between the display of the eco mark 40 and the display of the eco approach mark and the switching of the voice guidance output is individually set for the target achievement signal and the identification signal, and compared. Switching between the display of the eco mark 40 and the display of the eco approach mark when the number of continuous outputs of the goal achievement signal and the identification signal output from the determination unit 53 reaches the number of times set separately for each signal (set number of times). And switching voice guidance output. The set number of times may be different from each other or may be equal.

  Also, instead of switching the display of the eco mark 40 and the display of the eco approach mark or switching the voice guidance output according to the number of times the target achievement signal or identification signal is continuously output, the continuous output time is predetermined for each signal. When the set value (for example, 10 seconds) is reached, the display of the eco mark 40 and the display of the eco approach mark may be switched or the voice guidance output may be switched.

  The present embodiment is configured as described above. In the hot water supply system, the bath remote control device 1 having the hot water temperature setting priority function and the priority display function obtains an instantaneous value of the shower hot water use flow rate, and this instantaneous value. Is within the target range or the set flow rate range, and when the priority mark 42 is displayed, the determination result is notified by displaying the eco mark 40 or the eco approach mark and outputting voice guidance. Therefore, when the user uses the shower hot water supply, the user can know that the amount of use is the energy saving use amount or a value close to the energy saving use amount by the bath remote control device 1 provided in the vicinity of the shower. It can be easily and accurately informed and encourages users to use energy-saving showers.

  In addition, this invention can take various embodiment, without being limited to the said embodiment example. For example, in the above-described embodiment, when the user uses shower hot water, the usage amount is informed of the energy saving usage amount or a value close to the energy saving usage amount by both the mark display and the voice guidance output. However, the notification may be performed by either mark display or voice guidance output.

  In the embodiment, the target range and the set flow rate range are set. However, only the target range is set, and when the instantaneous value of the shower hot water use flow rate is a value within the target range, the eco mark 40 is displayed. It is also possible to simply output voice guidance. At this time, either one of the display of the eco-mark 40 and the output of the voice guidance may not be performed, and only one of them may be performed.

  Furthermore, in the embodiment, one set flow rate range is set. For example, when the target range is 6 to 12 liters / minute, the set flow rate ranges are 12 to 14 liters / minute and 14 to 16 liters. A plurality of different (adjacent) set flow rate ranges may be set, such as / min.

  In this case, for example, the comparison / determination unit 53 compares the instantaneous value of the shower hot water use flow rate detected by the shower hot water use value detection means when using shower hot water with the two set flow rate ranges, and the instantaneous value is the set flow rate. When it is determined that it falls within the range, an identification signal for identifying which set flow rate range the instantaneous value falls within is set. When the identification signal is output from the comparison / determination unit 53, the energy saving usage notification means 58 determines how close the shower hot water usage is to the energy saving usage corresponding to the identification signal. It is advisable to perform at least one of display and audio output for identification.

  For example, as an example of the mark display, when the instantaneous value of the shower hot water use flow rate is 12 to 14 liters / minute, the eco approach display means 56 causes the yellow eco approach mark to flash and display the instantaneous flow rate of the shower hot water use flow rate. When the value is 14 to 16 liters / minute, the eco approaching display means 56 blinks the orange eco approaching mark so that the user can see how much the shower is required only by looking at the display screen 32 at a glance. It is convenient to know whether the hot water use flow rate is close to energy saving use amount (close to eco-driving).

  Also, as an example of voice guidance output, voice guidance output from the speaker 34 by the voice output control unit 57 is “slightly more eco-friendly” when the instantaneous flow rate of shower hot water use is 12 to 14 liters / minute. When the instantaneous flow rate of shower hot water use is 14 to 16 liters / minute, the content of the voice guidance is slightly different from each other, such as “If you decrease the shower flow, it will approach eco-driving.” Correspondingly, by outputting voice guidance from the voice output unit that gradually identifies and expresses how close the shower hot water usage is to the energy-saving usage, It is possible to know if the shower water supply flow rate is close to energy-saving use amount (close to eco-driving) A.

  Furthermore, although the target range is set in the above embodiment, the target value may be set by the input setting operation means 52 instead of the target range. In this case, the comparison determination unit 53 compares the instantaneous value of the shower hot water use flow rate detected by the shower use instantaneous value detection means 51 with the target value, and determines that the instantaneous value is equal to or less than the target value. In such a case, a target achievement signal for the shower hot water use flow rate may be output to notify that the shower hot water use flow rate is the energy saving use amount.

  In the above embodiment, the set flow rate range is set in the vicinity region of the target range. Instead of the set flow rate range, the target approach value setting means 59 shown by the broken line in FIG. The means 59 may be configured to set a target approach value larger than the target value in the vicinity of the target value by the input setting operation means 52 or the automatic setting means. In this case, the comparison / determination unit 53 compares the instantaneous value of the shower hot water use flow rate detected by the shower hot water use value detection means 51 when using the shower hot water with the target value and the target approach value, and the instantaneous value is the target value. When it is determined that the value is greater than the value and less than or equal to the target approach value, a target approach signal for the shower hot water use flow rate is output.

  In this case as well, when the target approach signal is output from the comparison / determination unit 53, the energy saving use notifying means 58 indicates that the shower hot water supply use flow rate is a value close to the energy saving use amount, and at least displays and sounds. By notifying by one side, the effect similar to the said embodiment can be show | played.

  For example, when the target approach signal is output from the comparison determination unit 53, the eco approach display control unit 56 indicates that the shower hot water use flow rate is close to the energy saving use amount. The display of the eco approach mark or the like is performed on the display screen 32, and when the output of the target approach signal is stopped, the display of the eco approach mark is stopped. When the target approach signal is output from the comparison / determination unit 53, the sound output control means 57 outputs sound guidance from the speaker 34 indicating that the shower hot water use flow rate is close to the energy saving use amount. May be.

  Further, in the embodiment, the shower use instantaneous value detecting means 51 detects the instantaneous value of the shower hot water use flow rate at the time of shower hot water supply based on the detection value of the hot water supply flow rate sensor 49. The value detection means 51 may detect the instantaneous value of the shower hot water use flow rate at the time of shower hot water supply based on the detection value of the water supply flow rate sensor 4 and the detection value of the pouring water flow rate sensor 12.

  Furthermore, when the heat source device is a device having a hot water filling function as in the above-described embodiment, if the region where the device is installed is a low water pressure region, the flow rate during pouring (hot water filling) is small. In view of such a case, the eco mark may not be displayed during pouring.

  Further, when the state where the shower hot water flow rate is the energy saving usage amount continues for about 5 to 10 minutes, for example, the eco mark is not lit for about 5 to 10 minutes, but the eco mark display is stopped. , You may make it alert about continuous use.

  Furthermore, although the remote control device of the embodiment is the bath remote control device 1, the remote control device of the present invention may be the kitchen remote control device 2. Further, an additional remote control device that is electrically connected to the bath remote control device 1 or the kitchen remote control device 2 via the control device 3 may be provided in a bathroom, for example, and this additional remote control device may be used as the remote control device of the present invention. When the additional remote control device is the remote control device of the present invention, it is possible to inform the user who uses a shower in the bathroom for hair washing, for example, the energy saving usage status.

  Further, in this case, the comparison value determination unit 53 of the kitchen remote controller 2 or the additional remote controller compares the instantaneous value of the shower hot water use flow rate with the target value, the target range, the target approach value, and the set flow rate range, When the instantaneous value is an energy saving usage amount or when it is judged to be close to it, the fact is notified, and the comparison judgment result is transmitted to the bath remote control device 1 via the communication function. If the notification is made, it is possible to inform the user who is using the shower in the bathroom of the energy saving use status, and from the kitchen remote control device 2 etc. to the user in the vicinity of the energy saving use status. I can inform you.

  Furthermore, if the remote control device of the present invention is capable of detecting and judging whether or not the shower hot water use flow rate is an energy saving use amount or a value close to it, the details of other functions can be provided.
