  Next, an example of the operation of the hot water supply device 27 performed using the remote control device will be briefly described based on the schematic configuration of the hot water supply device 27 shown in FIG. Since the configuration of the hot water supply device 27 in FIG. 9 is known, the description of the configuration of the hot water supply device itself is omitted.

  The operation of the hot water supply function of the hot water supply device 27 is to turn on the operation switch 35 of the remote control device 1 or the kitchen remote control device 2 and open a hot water tap (not shown) provided at the hot water supply destination of the hot water supply line 11 in this state. Start by. When the hot water tap is opened, the control device 3 detects the flow rate exceeding the minimum operating flow rate through which the water supply pipe 5 is passed by the flow rate sensor 4, burns the hot water burner 10, and heats the water passing through the hot water heat exchanger 7. The hot water is prepared, and the hot water is supplied to the hot water supply destination through the hot water supply pipe 11.

  In the operation of the hot water supply function, the control device 3 determines the hot water temperature based on detection information of the incoming water temperature by the incoming water temperature sensor 6, the amount of hot water supplied by the flow rate sensor 4, and the hot water temperature (outlet temperature) by the hot water temperature sensor 8. The amount of gas supplied from the gas passage 9 is controlled by the opening amount of a proportional valve (not shown) so that the hot water supply set temperature set by the kitchen remote control device 2 (or the remote control device 1) is reached. The hot water supply operation is terminated when the hot water tap at the hot water supply destination is closed. That is, when the flow rate sensor 4 detects the stop of water flow by closing the hot-water tap, the control device 3 shuts off the gas supply to the hot-water supply burner 10 and stops the combustion of the hot-water supply burner 10.

  The automatic operation of the hot water supply device 27 continuously performs the operation of the hot water filling function, the operation of the reheating function, and the operation of the heat retaining function (the bath water temperature when the hot water filling is completed is the hot water filling set temperature (bath set temperature)). In the above case, the operation of the chasing function is not performed), and the operation is started by turning on the automatic switch 36 of the remote control device 1 (or the kitchen remote control device 2) while the operation switch 35 is turned on.

  Then, the hot water solenoid valve 13 is opened, and the water passing through the hot water heat exchanger 7 becomes hot water by the combustion heating of the hot water burner 10 as in the operation of the hot water supply function. 14, and is dropped into the bathtub 26 through a recirculation circuit 25 having a return pipe 23 and an outgoing pipe 24. The water level of the bathtub 26 is detected by a pressure sensor as the water level sensor 20, and when the detected water level reaches the set water level of the bathtub, the hot water solenoid valve 13 is closed and the hot water filling operation is completed. In this hot water filling operation, the control device 3 controls the combustion amount of the hot water supply burner 10 so that the hot water temperature of the hot water filling becomes the hot water filling set temperature.

  When hot water filling is completed, the hot water solenoid valve 13 is closed. Then, the circulation pump is activated, the temperature of the bath water (hot water temperature) is detected by the bath temperature sensor 18, and when the detected temperature is lower than the hot water set temperature (bath set temperature), the operation of the reheating function is performed.

  The operation of the reheating function is that the circulation pump 21 is driven and hot water in the bathtub 26 is circulated through the recirculation circulation path 25, and the bath burner 16 is combusted when this circulating water is detected by the flowing water switch 22. This is an operation of heating and recirculating hot water in the hot water bath to reheat the bath water when it is driven and passes through the reheating heat exchanger 15. This reheating operation ends when the bath temperature sensor 18 detects the bath temperature and when the detected temperature reaches the set bath temperature, the combustion of the bath burner 16 and the circulation pump 21 are stopped.

  And in the operation | movement of automatic operation, operation | movement of a heat retention function is performed continuously. The operation of this heat retention function is to start the circulation pump 21 for a short time at a predetermined time interval, recirculate hot water in the bathtub 26 and circulate it through the circulation path 25, and the hot water temperature (bath temperature) of the bathtub 26 by the bath temperature sensor 18. Is detected. When the detected temperature of the bath (tub hot water) falls below the allowable range below the set temperature of the bath, the circulation pump 21 is driven to recirculate hot water in the bathtub 26 and circulate through the circulation path 25 while the bath burner 16 Reheating is performed by the reheating heat exchanger 15 by combustion, and reheating is performed.

  Then, when the temperature detected by the bath temperature sensor 18 reaches the set temperature of the bath, the circulation pump 21 is stopped and the combustion of the bath burner 16 is stopped. As described above, the operation of the heat retaining function (the heat retaining operation) is performed for a predetermined time (for example, 4 hours) after the hot water filling is completed. In the hot water supply device 27 that performs the water retaining function together with the heat retaining function, the water level of the bathtub is monitored by the water level sensor 20, and the hot water solenoid valve 13 is opened when the water level of the bathtub drops beyond the allowable range from the set water level. Then, the amount of hot water that reaches the set water level from the hot water supply heat exchanger 7 side is replenished, and a water retention operation is performed to maintain the bathtub water level at the set water level.

  In addition, when the chase switch 33 of the remote control device 1 is pressed, the chase function is performed as a single operation. Further, when the additional hot water switch 30 of the remote control device 1 is pressed, the additional hot water function is operated, and a certain amount (for example, 20 liters) of hot water at a preset hot water temperature is dropped into the bathtub 26 from the hot water supply heat exchanger 7 side. It is. Further, when the warm water switch 31 of the remote control device 1 is pressed, the operation of the warm water function is performed, and a certain amount (for example, 10 liters) of feed water is dropped from the hot water supply heat exchanger 7 side to the bathtub 26 without being heated. I'm stuck.

  In FIG. 9, 12 is a flow sensor, 22 is a water flow switch, 19 is a conduit connecting the discharge port of the circulation pump 21 and the water intake of the reheating heat exchanger 15, and 17 is a gas passage to the bath burner 16. Respectively.

  In addition to the remote operation function of the hot water supply device 27, the remote control device 1 of the present embodiment has a function capable of receiving a radio wave of a broadcast having at least one of an audio broadcast and a text broadcast by adjusting a reception radio frequency. FIG. 1 shows a configuration for receiving and providing broadcast in an embodiment of a remote control device (remote control device 1) according to the present invention.

  This configuration includes a broadcast receiving unit (broadcast receiving module) 40, a character information writing / reading unit 41, a memory 42, a channel, provided inside the remote control device 1 (inside the housing case of the remote control device 1).

Since the configuration is known as shown in Patent Documents 1 and 3, etc., description of the circuit configuration is omitted. The broadcast receiving unit 40 also receives FM radio broadcasts, and the circuit board of the remote control device 1 includes a radio circuit that allows the FM radio broadcasts received by the broadcast receiving unit 40 to flow from the speakers 34. Since the circuit of such a radio is well known, the circuit configuration is not shown.

  In order for the broadcast receiving unit 40 to receive FM radio broadcasts or FM text broadcasts, it is necessary to adjust the reception radio frequency received by the broadcast reception unit 40 to the transmission radio frequency of the broadcast. The radio waves that can be received vary depending on the area where the remote control device 1 is located. Usually, when the hot water supply device 27 is installed, the received radio frequency is adjusted to match (match) the radio frequency transmitted from each broadcasting station. Done.

  In order to perform this frequency adjustment, in this embodiment, when the user operates the mode selection operation unit 47, a mode selection signal is applied to the operation unit 44 in the channel automatic setting mode, and the channel automatic operation described below is performed. Setting operation is performed. In the present embodiment, the selection switch 29 also serves as the mode selection operation unit 47. After the user presses the selection switch 29 for 2 seconds or more to enter the radio setting mode, the selection switch 29 is continued. When pressed, a mode selection signal is applied to the operation unit 44 of the following channel automatic setting mode.

  The automatic channel setting mode operation unit 44 variably adjusts the reception radio frequency received by the broadcast reception unit 40, and automatically stores the radio frequency of the broadcast that can be received by the adjustment and the broadcast station in association with each other. The operation is performed once or more, and each time the automatic storage operation is performed, an automatic channel setting operation is performed in which the stored broadcast station is set as one channel.

  The channel setting operation by the operation unit 44 in the channel automatic setting mode is not particularly limited. For example, the radio wave frequency of the broadcast that can be received and the broadcasting station are associated in order from the lowest radio wave frequency. In addition, the radio frequency and the broadcasting station are set in correspondence with channel numbers (for example, 1, 2,...). For example, a JFN affiliated station that performs character multiplex broadcasting is stored at the head, and then a broadcast station other than the JFN affiliate that performs character multiplex broadcasting is stored (in order of decreasing frequency of the JFN sequence, Remember in ascending order)
