The control unit is configured to execute mist spray interruption control for interrupting spraying of hot water for mist from the mist nozzle (mist ejection means) 4 (4a, 4b) when the flow rate has decreased. Therefore, it is possible to avoid discomfort to the user due to the fact that the hot water for mist is not properly ejected from the mist ejecting means in the form of a mist. It becomes possible to provide a heating dryer.

  Further, as described above, when the pressure drop of the mist hot water flowing through the mist hot water supply pipe 20 is eliminated, the mist spray interruption control is terminated and the mist nozzle (mist ejection means) 4 (4a, 4b) is used. Since the spraying of the hot water for mist is restarted, unnecessary suspending of the mist spraying can be avoided, and a bath mist device (bathroom heating dryer) that is more convenient to use can be realized.

  Further, as described above, the fact that the mist spray interruption control is being executed is indicated by alternately flashing the strong lamp (LED) 34a and the weak lamp (LED) 34b in the operating device 5 for the dressing room, and the bathroom. Since the user is notified by alternately flashing the strong lamp (LED) 134a and the weak lamp (LED) 134b in the operation device 30, the user knows that the mist spray interruption control is being executed. Therefore, it is possible to provide a bath mist device that is more convenient to use.

[Another embodiment]
FIG. 7 is a longitudinal sectional view showing a configuration of a bath mist apparatus according to another embodiment of the present invention.

  As shown in FIG. 7, the bath mist device includes a flow rate sensor FS that detects a flow rate per unit time of hot water for mist flowing through the hot water supply pipe 20 for mist, and includes a mist nozzle (mist ejection means). When the flow rate detected by the flow rate sensor FS drops to a predetermined flow rate (for example, 1.5 liters per minute) during execution of the mist operation for spraying hot water for mist from 4 (4a, 4b), the control unit B (Mist spraying means) 4 (4a, 4b) is configured to execute mist spray interruption control for interrupting spraying of hot water for mist from 4 (4a, 4b). Other configurations are the same as those of the above-described embodiment shown in FIGS.

  As described above, in the above embodiment, when the pressure in the mist hot water supply pipe 20 is measured by the pressure sensor PS and the pressure decreases to the predetermined first pressure, the flow rate of the mist hot water decreases. In this embodiment, when the flow rate of mist hot water is detected by the flow rate sensor FS and the detected flow rate is reduced to a predetermined flow rate, the mist spraying is performed. Interrupt control is executed.

  By configuring as in this another embodiment, the same effect as in the above embodiment can be obtained. Specifically, since a liquid heat exchanger is not required, the manufacturing cost can be reduced, and when the flow rate of hot water for mist flowing through the hot water supply pipe 20 for mist is reduced, hot water for mist is used. Since the spraying of mist is interrupted, it is possible to avoid discomfort to the user due to the fact that the hot water for mist is not properly ejected from the mist ejecting means in a mist form.

  Also in the case of the configuration of this other embodiment, a pressure sensor PS for detecting the pressure in the mist hot water supply pipe 20 is provided, and the detected pressure by the pressure sensor PS is restarted for a predetermined mist during execution of the mist spray interruption control. When the pressure rises to a pressure (for example, 0.2 MPa), the control unit B ends the mist spray interruption control and resumes spraying of hot water for mist from the mist nozzles (mist ejection means) 4 (4a, 4b). It is possible to configure. In such a configuration, when the flow of mist hot water flowing through the mist hot water supply pipe 20 is reduced and the mist spray interruption control is performed, when the pressure drop is eliminated, that is, the mist hot water supply pipe. When recovery of the flow rate of hot water for mist flowing through the passage 20 is confirmed, the mist spray interruption control is terminated and spraying of hot water for mist from the mist spraying means is restarted. An interruption can be avoided and a bath mist device that is easy to use can be provided.

  In this embodiment, the pressure sensor PS for detecting the pressure in the mist hot water supply line 20 is required when the mist spray interruption control is performed. This is because the mist hot water does not flow, and therefore the flow rate is detected, and the restart timing of spraying the mist hot water cannot be detected.

  The present invention is not limited to the above embodiment in other points, and various modifications can be made within the scope of the present invention.
