頻繁に繰り返されるという問題点を有していた。(Problems to be Solved by the Invention) In the conventional example described above, when the bath device is located far from the bathtub, it is necessary to install a cord for the water level detector, which raises concerns about cord breakage and electrical leakage. In addition, in this conventional water level detector, the diaphragm displaces and turns on when water pressure above a certain value is applied, so the difference in operating pressure between the on point and off point of the switch depends on the characteristics of the diaphragm. If the difference is small, on-off chatter is likely to occur. Therefore, when the water level of the bathtub is close to the set water level, the water level detector chattering when the water surface ripples, causing a problem in that the operation of refilling the bathtub with water starts and stops frequently.

きるのである。 The operation during automatic hot water supply will be explained below. It is necessary to exhaust the air in the path from the pressure sensor 9 to the bathtub 4, that is, the piping from the bypass path 10 to the bathtub 4 via the return pipe 6. For this purpose, the automatic hot water supply solenoid valve 17 is opened with the solenoid valves 22 and 25 closed, and hot water heated by the hot water supply heat exchanger 2 is supplied to the hopper 16. When the water level in the hopper 16 reaches the upper limit, the float switch 21 detects this and closes the automatic hot water supply solenoid valve 17, opens the solenoid valve 22 and the solenoid valve 8, and operates the pump 7. Then, the hot water in the hopper 16 mainly flows from the connecting pipe 23 via the pump 7 to the bypass path 10 with low water flow resistance. Because bath heat exchanger 3
Since the pipe is wound around the outer periphery of the heating cylinder and a fin-pipe-shaped heat absorbing part is formed inside the heating cylinder, it has many bent parts and has extremely high water flow resistance, so that the water is discharged from the pump 7. The heated hot water reaches the bath heat exchanger 3 and then flows to the bypass path 10 side where water flow resistance is small. The hot water flows backward through the water flow switch 11 from the bypass path 10, passes through the return pipe 6, and heads toward the bathtub 4. When the water level in the hopper 16 reaches the lower limit, the float switch 21 detects this and stops the pump 7, closes the solenoid valve 22 and the solenoid valve 8, and opens the automatic hot water supply solenoid valve 17. In this way, hot water is again supplied to the upper limit water level of the hopper 16 and sent to the return pipe 6 via the bypass path 10. The above-described operations are repeated a plurality of times to fill the bypass path 10 and return pipe 6 with hot water and exhaust air from the bath adapter 24. The number of times to repeat varies depending on the construction site depending on the length of the piping, etc., so it is determined during the above-mentioned test run and stored in the controller. Incidentally, a water flow sensor may be provided in the hot water supply pipe 15 or the connecting pipe 23 for the bath to measure the flow rate necessary for discharging the air. By utilizing the hopper 16, which is provided to prevent the risk of water flowing back into the municipal water pipe via the channel, the waste of using expensive water flow sensors can be eliminated.

磁弁２２を閉成し、ポンプ７を停止させる。 When the air evacuation operation is performed a predetermined number of times and the path from the pressure sensor 9 to the bus adapter 24 is filled with hot water, the solenoid valve 8 is closed and the output of the pressure sensor 9 is sampled. This air evacuation operation is always performed at the beginning of automatic hot water supply, so if there is hot water remaining in the bathtub 4 and the water level has already reached the set water level (set by a setting means such as a remote control not shown) at this point. If so, the automatic hot water supply is stopped, but if not, the automatic hot water supply solenoid valve 17 and the solenoid valve 22 are opened, the pump 7 is operated, and the route from the outgoing pipe 5 to the bathtub 4 passes through the bath heat exchanger 3. to supply hot water. While hot water is being supplied through this route, the output of the pressure sensor 9 is sampled, but until it is confirmed that the water level in the bathtub 4 has exceeded the bath adapter level (LBA), the solenoid valve is 8 is opened and hot water is supplied to the return pipe 6 side via the bypass path 10. That is, hot water is sent out alternately from the outgoing pipe 5 side and the return pipe 6 side. However, while the solenoid valve 8 is open and hot water is being supplied from the return pipe 6 side, the hot water supply pressure is transmitted to the pressure sensor 9, so the output of the pressure sensor 9 is not sampled. It is set as a short period of time. Since the valve 25 and the solenoid valve 8 are closed while hot water is being supplied from the outgoing pipe 5 side, neither the suction pressure nor the discharge pressure of the pump 7 is applied to the pressure sensor 9, and only the pressure due to the water level of the bathtub 4 is applied to the pressure sensor 9. Yes, and its output can be sampled continuously. The output of the pressure sensor 9 is compared with an output value (PSET) corresponding to a set water level arbitrarily set between the minimum water level (LMIN) and the full water level (LMAX), and an output that is equal to or higher than the output value (PSET) is determined. When detected, the automatic hot water supply solenoid valve 17 and the solenoid valve 22 are closed, and the pump 7 is stopped.
このようにして遠隔位置の浴槽４に所望の水位

所望水位で停止させることができる。 In this way, hot water can be automatically supplied to the bathtub 4 at a remote location up to the desired water level, regardless of whether or not there is hot water remaining in the bathtub 4 before automatic hot water supply starts, and even if air has entered the piping at the beginning. It can also be stopped at the desired water level with great precision.

い。 Incidentally, in order to reheat the hot water in the bathtub 4, the valve 25 is opened and the pump 7 is operated. The bath water sucked in from the return pipe 6 is heated by a bath heat exchanger 3 heated by a signal from the water flow switch 11, and reaches the bathtub 4 from the outgoing pipe 5. When the water temperature sensor 12 detects a preset temperature, This cyclical heating is automatically stopped. In addition, during this reburning, valve 2
5 is open, the pressure sensor 9 is affected by the suction pressure of the pump 7, and therefore does not detect the water level.

４に給湯するのである。 Furthermore, in the present invention, it is possible to detect a drop in the water level in the bathtub 4 due to the use of bath water during bathing, and to automatically replenish water up to a set water level. That is, when the output of the pressure sensor 9 decreases by a predetermined value or more than the output value (PSET) corresponding to the set water level, the automatic hot water supply solenoid valve 17 and the solenoid valve 22 are opened, and the pump 7 is opened.
is operated to supply hot water to the bathtub 4 via the bath heat exchanger 3 and the outgoing pipe 5.

に所定の確認時間(t)を設けている。 At this time, even if the water level in the bathtub 4 is higher than the set water level, if the water surface ripples, the output of the pressure sensor 9 will oscillate above and below the output value (PSET), and the start and stop of the water replenishment operation will be repeated frequently. The signal goes into a chattering state. Therefore, a predetermined confirmation time (t) is provided so that the water replenishment operation is started when the output of the pressure sensor 9 continues to be lower than the set water level (PSET) by a predetermined value or more for a predetermined period of time.

防止することができる。(Effects of the Invention) The automatic bath device of the present invention has the following excellent effects. In other words, since the semiconductor pressure sensor is connected to the bath circuit and installed inside the device body, there is no need to install a signal code for water level detection between the bathtub and the device body, simplifying the installation. At the same time, the risk of cord disconnection and electrical leakage is reduced, and the inconvenience of automatic refilling when the water level of the bathtub is low, in which the refilling operation is repeatedly started and stopped due to false detection due to waving of the bathtub water surface, etc., can be prevented. Can be done.
