The air pressure is gradually increased. The tank 23 is provided with a pressure detection sensor.
When the air pressure in 23 reaches the set pressure, the control board 12
By opening the solenoid valve 20 by the control circuit of
The compressed air in the tank 23 passes through the discharge line 24 and the circulation line 4
The water remaining in the circulation pipe is discharged into the bathtub 13 from the return pipe 1 and the forward pipe 2 by the blowing of the compressed air, and the water remaining in the circulation pipe 4 is empty. State. The air pump 22 may be stopped by a manual operation of the button 25, or automatically stopped when a predetermined time has elapsed since the solenoid valve 20 was opened or when the air pressure in the tank 23 decreases to a predetermined pressure. It can also be done.

According to this embodiment, the remaining water in the circulation pipe 4 is reliably blown out and discharged into the bathtub 13 by operating the compressed air blowing means 21, so that the remaining water in the pipe is removed. Freezing will no longer occur, and the fear of line rupture due to this freezing will be completely eliminated.

FIG. 2 shows a second embodiment of the present invention. The second embodiment corresponds to the conventional bubble bath apparatus shown in FIGS. 4 and 5, and in this embodiment, a compressed air blowing means 21 is connected to the circulation line 4 of the bubble bath. . The structure and operation of the compressed air blowing means 21 are the same as those in the first embodiment. After the use of the bubble bath, the hot and cold water in the bathtub is discharged, and then the compressed air blowing means 21 is operated to circulate the bubble bath. The remaining water remaining in the pipe 4 is surely discharged into the bathtub 13, and the pipe rupture due to freezing of the remaining water in the circulation pipe 4 in a cold region as in the first embodiment.

Instead of the solenoid valve 20, a manual valve is used. When the pump 22 is driven to increase the pressure in the tank 23 to the set pressure, the manual valve may be opened to blow out compressed air from the tank 23 to the circulation line 4 side.

Further, in each of the above embodiments, the button 25 for operating the compressed air blowing means 21 is provided on the remote controller 9. However, this button 25 is provided on an appropriate place such as a housing panel surface of the air pump 22 or a bathroom wall surface. Can be provided.

Further, in each of the above embodiments, the operation of the compressed air blowing means 21 is performed by operating the button 25. However, for example, a water level sensor for detecting the water level of the bathtub 13 is provided, and the bathtub water level is controlled. The air pump 22 may be operated upon receiving the detection signal of the water level sensor when the water level falls below the connection port of the circulation pipeline 4 which is the set water level , or when the bathtub hot water is drained or drained. The air pump 22 is operated beforehand to increase the air pressure in the tank 23, and when the bathtub water level falls below the connection port of the circulation line 4, the solenoid valve 20 is opened to release the compressed air into the circulation line 4. The compressed air blowing means 21 may be operated in various ways, for example, by blowing it out.

Further, in the first embodiment, the bath apparatus with the hot water supply function has been described. However, the present invention can be applied to a bath apparatus only for reheating without a hot water supply function.
