The bathroom heater / dryer 1 is installed, for example, behind the ceiling of the bathroom 9, and the hot air outlet 19 and the like are exposed inside the bathroom 9. The hot air outlet 19 is arranged at a position on the ceiling, for example, facing the bathtub 20.
[0012]
The bathroom heater / dryer 1 is connected to a heat source unit 13 installed outdoors by a hot water pipe 14. The hot water heated by the heat source unit 13 is sent to the bathroom heating / drying machine 1 through an outgoing pipe 15 in a hot water pipe 14. The bathroom heater / dryer 1 is provided with a heat exchanger 17 for exchanging heat between the hot water passing through the outflow pipe 15 and air. The hot water cooled by the heat exchange returns to the heat source unit 13 through the return pipe 16 in the hot water pipe 14, is heated again by the heat source unit 13, and is sent to the bathroom heating / drying machine 1. In this way, the hot water in the hot water pipe 14 circulates between the heat source device 13 and the bathroom heating / drying machine 1. The bathroom heater / dryer 1 has a circulating fan 18 that sends air whose temperature has been increased by heat exchange into the bathroom 9. The humid air containing water vapor in the bathroom 9 is sucked by a ventilation fan (not shown) provided in the bathroom heater / dryer 1 and is discharged outside through an exhaust duct (not shown). Thereby, the inside of the bathroom 9 can be efficiently dried while circulating the air in the bathroom 9.
[0013]
Further, the bathroom heating / drying machine 1 is provided with, for example, two speakers 3 for audio output. The speaker 3 is installed such that the direction of the speaker cone is adjusted so that sound is sufficiently output into the bathroom 9. Further, the bathroom heater / dryer 1 includes an amplifier 2 that amplifies the audio signal and outputs the amplified audio signal to the speaker 3. The amplifier 2 is connected to the speaker 3 via the signal line 10. Further, the amplifier 2 is connected via a signal line 8 to a remote control 7 for a bathroom heating / drying machine attached outside the bathroom 9 (for example, in a dressing room).
[0014]
The bathroom heating / drying machine remote controller 7 controls the heating and drying operations of the bathroom heating / drying machine 1 together with a sound from a music reproducing device 11 such as a commercially available portable CD player placed at a predetermined position in a dressing room. An audio input terminal for inputting a signal is provided. The music playback device 11 generally includes a headphone jack (not shown) for audio output. At both ends of the cable of the signal line 12, there are provided plugs which are detachably inserted into a sound input terminal of the remote control 7 for the bathroom heating / drying machine and a headphone jack of the music reproducing device 11, respectively. As the music playback device 11 serving as a sound source, a cassette tape playback device, a portable radio, or the like can be used in addition to a portable CD player.
[0015]
The bathroom heater / dryer 1 includes a power supply device 4 for driving the amplifier 2. The power supply device 4 is connected to a power supply line 5 that transmits an AC voltage of 100 V (AC 100 V). Further, the power supply device 4 includes an AC-DC converter that converts AC 100 V to a DC voltage of 25 V (DC 25 V), and a DC-DC converter that generates a DC voltage for driving each circuit of the amplifier 2 from DC 25 V (both are used). (Not shown).
[0016]
Next, the operation of the bathroom heater / dryer 1 according to the present embodiment will be described. The audio signal output from the music playback device 11 is input to the bathroom heating / drying remote controller 7 via the signal line 12 and further output to the amplifier 2 via the signal line 8.
[0017]
Here, it is assumed that the amplifier 2 uses the DC 25 V generated by the power supply device 4 as a power supply. The maximum drive voltage of the amplifier 2 becomes lower than the power supply voltage due to the voltage loss of each circuit in the amplifier 2. Assuming that the voltage loss of the amplifier 2 is 2 V, the maximum drive voltage of the amplifier 2 is 23 V, and the effective voltage of the amplifier 2 is 23 / √2 = 16.3 V. Assuming that the impedance of the speaker 3 is 8Ω, the maximum output power of the amplifier 2 is (16.3 × 16.3) /8=33.2 W.
[0018]
Generally, considering that the maximum output power of a stationary system component for indoor use in which a music playback mechanism, an amplifier, a speaker, and the like are integrated is about 15 W to 40 W, the amplifier of the bathroom heating / drying machine 1 according to the present embodiment. It can be seen that No. 2 can achieve a powerful volume equivalent to a stationary system component.
[0019]
Since the bathroom heater / dryer 1 of the present embodiment incorporates the amplifier 2, the speaker 3 and the power supply device 4 and has substantially the same size as the conventional bathroom heater / dryer, The machine can be easily replaced. Further, it is not necessary to provide a hole for installing the speaker 3 on the wall surface in the bathroom 9 as in the related art. In addition, since the remote control 7 for the bathroom heater / dryer is provided with the audio input terminal, the remote controller 7 for the bathroom heater / dryer of the present embodiment is simply installed in place of the conventional remote controller for the bathroom heater / dryer, and the audio signal of the audio signal is provided. An input terminal can be provided. Therefore, there is no need to provide a hole for an audio signal input terminal on a wall or the like of a dressing room.
[0020]
In addition, the power supply device 4 generates a voltage for driving the amplifier 2 based on 100 V AC transmitted to the power supply line 5. Accordingly, all functions such as a bathroom heating function and a sound output function are exhibited only by supplying electric power from the power supply line 5 to the bathroom heating / drying machine 1. For this reason, even if an audio output device such as the speaker 3 is added, the method of supplying power to the bathroom heating / drying machine 1 is not different from the conventional bathroom heating / drying machine. Further, the wiring such as the underside of the ceiling may be only the signal line 8 for connecting the bathroom heating / drying machine 1 and the bathroom heating / drying machine remote controller 7. Thus, the installation work of the bathroom heating / drying machine 1 and the remote control 7 for the bathroom heating / drying machine is extremely simple.
