確保するものである。In other words, even if the pump start/stop circuit and the pump malfunction and the pump runs out of control, if the water temperature in the bathtub exceeds a predetermined temperature, the water temperature inside the bathtub will become low, so even if the pump runs continuously, It is possible to prevent the water temperature in the bathtub from rising without transmitting the heat of the high-temperature water to the water in the bathtub. This prevents burns and the like and ensures safety.
実施例 以下、本発明の一実施例を図面に基づいて説明する。Example Hereinafter, one embodiment of the present invention will be described based on the drawings.
第２図において、１１は追焚き装置で、缶体１２の中に

。Reference numeral 17 denotes a control device, which includes a burner control circuit 18, a temperature detection circuit 19, a pump start/stop circuit 20, and a safety circuit 21.
Furthermore, the temperature detection circuit 19 is electrically connected to a temperature detector 23 attached to the return pipe 16, and the pump start/stop circuit 20 is electrically connected to a pump 24 attached to the outgoing pipe 15.
次にこの一実施例の構成における作用を説明する。Next, the operation of the configuration of this embodiment will be explained.
第１図において、運転スイッチと風呂スイッチをＯＮし

いか高いかを判定し、ポンプ発停回路２０によって設定
値より低ければポンプ２４を運転し缶体１２内の温水の
熱を浴槽１４内の水に伝達することによって追焚きをし
設定値より高くなったらポンプ２４を停止させ、この・
動作によって浴槽１４内の水温は常に適温にコントロー
ルすることができるものである。In FIG. 1, after turning on the operation switch and the bath switch, the burner control circuit 18 controls the operation of the burner 22 so that the water temperature inside the can body 12 is maintained at a high temperature of approximately 70°C to 90°C. The temperature detector 23 and the temperature detection circuit 19 detect the water temperature in the bathtub 14 and determine whether it is lower or higher than the set value, and the pump start/stop circuit 20 operates the pump 24 if the temperature is lower than the set value. The heat of the hot water is transferred to the water in the bathtub 14 to reheat the water, and when the temperature rises above the set value, the pump 24 is stopped, and this
The temperature of the water in the bathtub 14 can always be controlled to an appropriate temperature by the operation.
次に安全回路２１の作用を説明する。浴槽１４内の水温
が設定値より高くなった場合まずポンプ２４を停止させ
るが、その時に温度検知器２３および温度検知回路１９
によって浴槽１４内の水温が所定温度（安全温度）より
高いと検知し、さらにタイマーによって一定時間経過し
た後にも所定温度（安全温度）より高いと検知した場合
、缶体１２内の水温が低（なるようにバーナ２２の運転
を制御するとともに本実施例では警告ブザーの音を発す
るようにするものである。Next, the operation of the safety circuit 21 will be explained. When the water temperature in the bathtub 14 becomes higher than the set value, the pump 24 is first stopped, but at that time the temperature detector 23 and the temperature detection circuit 19
If the timer detects that the water temperature in the bathtub 14 is higher than the predetermined temperature (safety temperature), and the timer also detects that the water temperature is higher than the predetermined temperature (safety temperature) after a certain period of time, the water temperature in the can body 12 is low ( In this embodiment, the operation of the burner 22 is controlled so that the warning buzzer sounds.
この結果ポンプ発停回路２０およびポンプ２４が故障し
ポンプ２４が暴走した場合でも、浴槽１４内の水温が安
全温度以上になった場合、缶体１２内の水温が低くなる
ため、ポンプ２４が連続で運転しても缶体１２内の高温
水の熱を浴槽１４内の水に伝えることなく浴槽１４内の
水温の上昇を防止することができるものである。それに
よって火傷などを未然に防止し、安全性を確保するとと
もに、警告ブザーによって故障を知らせることができる
ものである。As a result, even if the pump start/stop circuit 20 and the pump 24 break down and the pump 24 runs out of control, if the water temperature in the bathtub 14 exceeds the safe temperature, the water temperature in the can body 12 will become low and the pump 24 will continue operating. Even if the bathtub is operated at 100 degrees, the heat of the high-temperature water in the can body 12 is not transferred to the water in the bathtub 14, and an increase in the water temperature in the bathtub 14 can be prevented. This prevents burns and other injuries, ensuring safety, and also alerts you to malfunctions with a warning buzzer.
