（産業上の利用分野）
本発明は自動給湯風呂装置に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic hot water bath device.
（従来の技術）
従来より、特開昭63−21439号公報に示される
ように、追焚用の循環路に圧力センサを設けて浴
槽内の水位を検出し、給湯器からホツパー及び循
環路を介して浴槽に湯水を落とし込むようにした
ものが知られている。(Prior art) Conventionally, as shown in Japanese Patent Application Laid-Open No. 63-21439, a pressure sensor is installed in the reheating circulation path to detect the water level in the bathtub, and the hopper and circulation path are connected from the water heater to the hot water heater. A bathtub in which hot water is poured into a bathtub through a bathtub is known.

れていない圧力センサが浴槽水位に基づく正確な
水圧を検知することができないため、自動運転ス
イツチがオンになると必ず循環路に一定量の湯水
を供給して循環路内のエアパージを行なうように
している。 With this conventional system, the pressure sensor cannot accurately detect the water pressure based on the bath water level because the circulation path is not filled with hot water, so when the automatic operation switch is turned on, a certain amount of hot water is always added to the circulation path. The system supplies air to purge the circulation path.
（発明が解決しようとする課題）
しかし、この従来のものでは既に浴槽内に設定
水位以上の湯水が溜まつている状態で自動運転ス
イツチがオンされると、エアパージのために供給
される湯水の量だけ浴槽水位が無用に上昇し、使
用勝手が悪く、浴槽からオーバーフローすること
もあるという問題点を有していた。(Problem to be solved by the invention) However, with this conventional bathtub, when the automatic operation switch is turned on with hot water above the set water level already accumulated in the bathtub, the hot water is supplied for air purge. The problem is that the water level in the bathtub rises unnecessarily by the same amount of water, making it inconvenient to use and sometimes overflowing from the bathtub.

冬期にはこのホツパー内の残水が凍結する問題点
を有していた。 Also, if the automatic operation switch is turned off during this air purge or while hot water is being poured into the bathtub, the hot water supply will stop, but at the same time, the communication between the hopper and the circulation path will be cut off, so hot water will not flow into the hopper. Since the hopper is built into the main body which is installed outdoors at a distance from the bathtub, there is a problem in that the remaining water in the hopper freezes in the winter.

自動給湯風呂装置の提供を目的としている。 The present invention solves these conventional problems, and even if the automatic operation switch is turned off during automatic hot water supply, hot water will not remain in the hopper, and the water level in the bathtub will rise the next time the automatic operation switch is turned on. The purpose of the present invention is to provide an automatic hot water bath device that can detect the water level from the beginning without any trouble.

にしている。(Means for Solving the Problems) In order to achieve the above object, the automatic hot water bath apparatus of the present invention has the following configuration. In other words, when the automatic operation switch is turned on, hot water is dropped from the water heater into the bathtub via the hopper and reheating circulation path, and a pressure sensor installed in the circulation path detects the water level in the bathtub, and the set water level is detected. The system then automatically stops the pouring process and reheats the heat to the set temperature. When the automatic operation switch is turned off, the remaining water in the hopper is drained and hot water from the bathtub is circulated through the circulation path to air purge the circulation path. I try to do that.

は最初から水位を検知することができる。(Function) When the automatic operation switch is turned off, if hot water is being poured from the water heater into the bathtub, it will stop pouring water into the bathtub, and if the pump is stopped, it will operate the pump to drain the remaining water in the hopper into the circulation path. to be discharged. When the remaining water in the hopper is discharged, communication between the hopper and the circulation path is cut off, and the pump continues to operate for a certain period of time to circulate hot water from the bathtub through the circulation path. In other words, in order to completely drain the remaining water in the hopper, it is unavoidable to draw some air from the hopper into the circulation path, but by circulating hot water through the circulation path, this air can be removed from the bathtub. The circulation path is filled with hot water so that the pressure sensor can detect the water pressure based on the water level in the bathtub. Therefore, the water level of the bathtub can be detected even while the automatic operation switch is off, and the next time the automatic operation switch is turned on, the water level can be detected from the beginning.

合はエアパージも落とし込みも行なわない。 When the operation switch 26 is turned on and the automatic operation switch 25 is turned on, the water level detected by the pressure sensor 12 is read and compared with the set water level set by the water level setting switch 18 of the remote control 16, as shown in FIG. If the water level is below the set level, solenoid valve 2
4, operate pump 9, bypass solenoid valve 1
4 is opened to allow hot water supplied from the water heater 2 to flow into the circulation path 7, filling the circulation path 7 with hot water and air purging. Bypass solenoid valve 1 when a certain amount of hot water flows
4 is closed, and while the water level is detected by the pressure sensor 12 via the piping 7A, hot water supplied from the water heater 2 is dropped into the bathtub 6 through the other piping, and when the pressure sensor 12 detects the set water level, the solenoid valve 24 is closed. At the same time, the three-way valve 8 is switched from the hopper 5 side to the circulation path 7 side. On the other hand, if the pressure sensor 12 detects the water level above the set level from the beginning, neither air purge nor dropping is performed.

すると追焚を停止して保温・補水モードに移る。 Then, when the three-way valve 8 is switched, the hot water in the bathtub 6 is circulated through the circulation path 7, and when the water flow detection means 10 detects the circulating water flow, the process shifts to reheating, and the hot water temperature detection means 11 sets the hot water temperature with the hot water temperature setting switch 19. When it detects the set temperature, it stops reheating and shifts to heat retention/water replenishment mode.

のである。 In heat retention/water replenishment mode, for a certain period of time (e.g. 30
The water level detected by the pressure sensor 12 is read every minute (minutes), and if the water level has decreased below the set water level, hot water is poured from the water heater 2 into the bathtub 6, and the pump 9
The water temperature in the bathtub 6 is detected by the hot water temperature detecting means 11, and if the temperature is lower than the set temperature, reheating is performed.

作することも考えられる。 After such heat retention and water replenishment operations are performed for a certain period of time (for example, 4 hours) predetermined by the heat retention timer, the automatic operation switch 25 is automatically turned off. However, it is also conceivable that the user turns off the automatic operation switch 25 or operation switch 26 before that.

る。 FIG. 3 is a control flowchart when the automatic operation switch 25 is turned off. First, if the three-way valve 8 is not communicating with the hopper 5 side, it is switched to the hopper 5 side, and the pump 9 is operated to open the hopper 5. The remaining water is discharged into the circulation path 7. Then, when all the float switches 51 of the hopper 5 are turned off, the three-way valve 8, which detects when the water has been completely drained, is switched to the circulation path 7 side, and the hot water in the bathtub 6 is circulated through the circulation path 7 for a certain period of time. When the remaining water is discharged, the air sucked into the circulation path 7 is discharged into the bathtub 6.

き、既に浴槽６に設定水位以上の湯水が溜まつて
いる場合に無用に水位を上昇させることがない。 Therefore, even if the automatic operation switch 25 is turned off and the automatic operation is stopped in the middle of automatic operation, hot water will not remain in the hopper 5, and after draining the remaining water in the hopper 5, the circulation path 7 can be opened. The pressure sensor 12 is connected to the bathtub 6 by air purging by circulating hot water.
As shown in FIG. 2, the next time the automatic operation switch 25 is turned on, the water level can be detected first, and the water level in the bathtub 6 is already higher than the set water level. This prevents the water level from rising unnecessarily when water is accumulating.

安全動作することを防止している。 In addition, as a special case, if the piping of the circulation path 7 between the bathtub 6 and the main body 1 is raised to a higher position than the bathtub 6 (so-called torii piping), the hot water in the bathtub 6 may be Even if the water is drained, hot water remains in the piping from the above-mentioned startup part to the main body 1 of the device.
It is possible that the pressure sensor 12 detects a water level higher than the set water level, but the circulation path 7
If circulating water flow from hot water in the bathtub 6 is not detected, the system returns to the air purge sequence to prevent abnormality determination and safe operation.
