【発明の属する技術分野】
本発明は、浴槽の側壁に取り付けられたアダプタを介して浴槽へのお湯張りを行う給湯装置に関するものである。
【0002】
【従来の技術】
従来の給湯装置においては、給湯装置にヒーターを内蔵し加熱するという手段がとられているが、厳しい冷え込みに遭遇した場合には、配管が凍結して使用出来なくなることがある。
そのため、厳しい冷え込みが予想されるときは、リモコンに備えられた凍結予防スイッチを入れ、給湯栓を開放しておけば、水温や気温が所定の温度以下になったとき、所定の流量の水を給湯栓から排水させ、水温や気温が所定温度以上になったとき、給湯栓からの排水を停止させることにより凍結を防止する給湯装置が提案されている(例えば、特許文献1、2を参照。)。
また、節水のため、微小流量検出手段を用いて給湯栓から排水させる流量を最小流量とする凍結防止装置も提案されている(例えば、特許文献3を参照。)。

【発明が解決しようとする課題】
ところが、従来の給湯装置の凍結防止方法では、水温や気温で給湯栓からの排出を制御したり、排出される流量を出来るだけ最小にするようにしても、なお、給湯栓から排出される水は垂れ流しとなるので、水が無駄になるという問題があった。
なお、水の無駄を避けるために、給湯栓の下にバケツ等を置いて、再利用することが考えられるが、面倒であるという問題がある。
あるいは、浴槽の給湯栓を開いて、浴槽に溜めることも考えられるが、給湯栓の開け閉めの手間がかかるという問題は残る。
本発明は、上記課題を解決するためになされたもので、本発明の目的は、水を無駄に流すことなく、かつ手間が無く、凍結防止が可能な給湯装置を提供することにある。
【0005】
【課題を解決するための手段及びその作用・効果】
上記目的を達成するために請求項1は、浴槽の側壁に取り付けられたアダプタを介して浴槽へのお湯張りを行う給湯装置であって、前記給湯装置は、リモコンに凍結防止スイッチを備えるとともに、前記給湯装置が設置されている雰囲気の温度を検出する外気温度検出手段又は、前記給湯装置へ供給される水の温度を検出する入水温度検出手段を備え、前記凍結防止スイッチの操作により、前記外気温度検出手段又は、前記入水温度検出手段の検出値が予め決められた所定値以下となったとき、予め決められた所定の流量の水を、前記アダプタより浴槽へ供給する凍結防止手段を備えたので、雰囲気温度や水温が低くなると、浴槽の壁面に取り付けられたアダプタから所定の流量の水が排出されることとなり、給湯栓を開け閉めすることなく、浴槽に水を溜めることが出来て、水を無駄にすることなく、かつ手間が無く、凍結防止が可能となる。
【0006】
【発明の実施の形態】
以下、本発明の実施の形態を、図面により詳細に説明する。
図1は、本発明の一実施形態に係るガス給湯機を示したブロック図である。
上記ガス給湯機は、図示のように、給湯機本体1、給水源から給湯機本体1に水を供給するための給水管3、及び給湯機本体1内の熱交換器7で加熱された水を給湯栓11に供給するための給湯管5で構成されている。更に、給湯機本体1内の給水管3から分岐し、熱交換器7を介さずに給湯管5に接続されるバイパス管43が備えられ、バイパス管43と給湯管5の合流部には、熱交換器7で加熱された湯と、バイパス管43から送られてきた水を指令パルスに基づき駆動するステッピングモータMにより混合制御する混合弁41が備えられている。
また、給水管3には、給水源からの水の温度Tcを検出する入水温度センサ25、及び水の流量Qを検出する水量センサ27、給湯管5の混合弁41よりも上流側には、熱交換器7の出口温度Thを検出する熱交換器出口温度センサ45、混合弁41よりも下流側には、混合された後の混合湯温Tmを検出する混合湯温検出センサ29、流量Qを制御するための水量バルブ62が備えられている。
【0007】
また、給湯機本体1内には、燃焼するのに必要な空気を供給するためのファン9をも備える。
更に、バーナ13の上部には着火させる際に必要なイグナイタ15、火炎の有無を検出するフレームロッド17が設けられている。また、バーナ13にガスを供給するためのガス供給管23が設けられ、ガス供給管23には供給するガス量を可変するための比例弁19及びガスの供給を開始/停止するための電磁弁21が備えられている。
【0008】
更に、上記ガス給湯機は、水量バルブ62よりも下流で給湯機本体1内の給湯管5から、追焚戻り管2に接続された湯張り管4を備え、湯張り管4には、湯張り管4を流れる流量Qhを検出する風呂水量センサ8及び湯の供給を開始/停止するための温水電磁弁6が設けられている。
また、上記ガス給湯機には、給湯機本体1が設置されている雰囲気の温度を検出するための外気温度検出センサ61が備えられている。
【0009】
一方、追焚戻り管2及び追焚往き管53は端部を浴槽12内に取り付けられた循環アダプタ55に接続され、中途には浴槽12内の湯を循環させるための循環ポンプP、浴槽12の水位を検出する水位センサ10、浴槽12内の湯温を検出する風呂温度センサ49、追焚戻り管2を熱交換器7を介さずに熱交バイパス管14を経由して追焚往き管53へ連絡させることのできるモータM2で駆動される熱交三方弁51を備える。
【0010】
従って、熱交三方弁51を熱交位置へ動かした場合は、追焚戻り管2→熱交換器7→追焚往き管53とつながる第1循環経路を形成し、熱交三方弁51をバイパス位置へ動かした場合は、追焚戻り管2→熱交バイパス管14→追焚往き管53とつながる第2循環経路を形成する構成となっている。
【0011】
また、浴槽12の底面には、浴槽12内の湯を排水するための排水栓60が備えられている。
また、リモコン33には、運転スイッチ35、給湯栓11から供給される湯温の設定温度Ts、浴槽12へ湯張りする湯温の風呂設定温度Tfs等を設定する設定スイッチ39、浴槽12へ湯張りする際にオン操作する湯張りスイッチ36、浴槽12内の湯を加熱する際にオン操作する追焚スイッチ38、凍結防止動作をさせるための凍結防止スイッチ32、設定温度Ts、風呂設定温度Tfs等を表示する表示部37を備える。
【0012】
上記ガス給湯機は更に、上記各センサ25、27、45、29および設定スイッチ39等からの検出信号(Tc、Q、Th、Tm、Ts、Tfs等)に基づき、比例弁19、電磁弁21、ファン9、混合弁41等の制御を行う制御部31をも備える。
また、制御部31は排水栓60の開閉動作を制御出来る。
【0013】
ここで、リモコン33に備えられた凍結防止スイッチ32をオン操作すると、入水温度センサ25の検出信号Tc、又は外気温度検出センサ61の検出信号Tgが予め決められた所定値以下になったとき、制御部31が排水栓60を閉めた後、温水電磁弁6を開き、給水管3→熱交換器7及びバイパス管43→給湯管5→湯張り管4→追焚戻り管2及び追焚往き管53(熱交三方弁51はバイパス位置)→循環アダプタ55の経路で浴槽12へお湯張りが行われる。
なお、お湯張りの流量は予め決められた流量(凍結を防止するに足りる最小流量)とし、風呂水量センサ8の検出流量Qhに基づき、水量バルブ62により制御される。
そして、入水温度センサ25の検出信号Tc、又は外気温度検出センサ61の検出信号Tgが予め決められた所定値を超えたとき、お湯張りを停止する。
このとき、お湯張りされた積算流量は制御部31に記憶される。
なお、凍結防止スイッチ32がオンになっているときは、流量Qhに拘らず、バーナ13は燃焼しない。
【0014】
そして入浴の際、湯張りスイッチ36を押すと、設定スイッチ39で設定された湯張り量の設定値から、凍結防止動作によりお湯張りされた積算流量を差し引いた量のお湯張りを行い、設定温度Tfsまで追焚きを行う。
従って、入水温度センサ25の検出信号Tc、又は外気温度検出センサ61の検出信号Tgが予め決められた所定値以下になったとき、循環アダプタ55から所定の流量(凍結を防止するに足りる最小流量)の水が排出されることより、給湯栓11を開け閉めする手間がなく、給湯機本体1の凍結を防止することが出来る。
更に、入浴の際には、浴槽12内に溜まった水の量を差し引いてお湯張りするようにしたので、水を無駄にすることもない。
【0015】
次に、図2のフローチャート図をもとに、詳細な凍結防止動作を説明する。
ステップS1で、凍結防止スイッチ32がオン操作されたか否かを判断し、凍結防止スイッチ32がオン操作されたと判断した場合は、入水温度センサ25の検出信号Tsを基に、水温が予め決められた所定の温度以下か否かを判断する(ステップS2)。
ステップS2で、水温が所定の温度以下であると判断すると、ステップS3で浴槽12に備えられた排水栓60を閉じて、ステップS4で温水電磁弁6を開いてお湯張りを行い、再度ステップS1へ戻る。
この時、お湯張りの流量は所定の流量(凍結を防止するに足りる最小流量)に制御される。
また、ステップS1で凍結防止スイッチ32がオフの場合、ステップS2で水温が所定温度を超えたと判断した場合は、ステップS5で温水電磁弁6を閉じてお湯張りを停止し、ステップS1へ戻る。
なお、ここでは、入水温度センサ25の検出信号Tsをもとにしたが、外気温度検出センサ61の検出信号Tgをもとにしてもよい。
【0016】
従って、雰囲気温度や水温が低くなると、浴槽の壁面に取り付けられたアダプタから所定の流量の水が排出されることとなり、給湯栓を開け閉めすることなく、浴槽に水を溜めることが出来て、水を無駄にすることなく、かつ手間が無く、凍結防止が可能となる。

[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a block diagram showing a gas water heater according to one embodiment of the present invention.
As shown in the figure, the gas water heater includes a water heater main body 1, a water supply pipe 3 for supplying water from a water supply source to the water heater main body 1, and water heated by a heat exchanger 7 in the water heater main body 1. Is supplied to the hot-water tap 11. Further, a bypass pipe 43 is provided, which branches off from the water supply pipe 3 in the water heater main body 1 and is connected to the hot water supply pipe 5 without passing through the heat exchanger 7. A mixing valve 41 is provided for mixing and controlling the hot water heated by the heat exchanger 7 and the water sent from the bypass pipe 43 by a stepping motor M driven based on a command pulse.
In addition, the water supply pipe 3 has an incoming water temperature sensor 25 for detecting the temperature Tc of water from the water supply source, a water quantity sensor 27 for detecting the flow rate Q of water, and an upstream side of the mixing valve 41 of the hot water supply pipe 5. A heat exchanger outlet temperature sensor 45 for detecting an outlet temperature Th of the heat exchanger 7, a mixed hot water temperature detection sensor 29 for detecting a mixed hot water temperature Tm after mixing, and a flow rate Q downstream of the mixing valve 41. Is provided with a water quantity valve 62 for controlling the pressure.
[0007]
The water heater main body 1 also includes a fan 9 for supplying air required for combustion.
Further, an igniter 15 necessary for igniting and a frame rod 17 for detecting the presence or absence of a flame are provided above the burner 13. A gas supply pipe 23 for supplying gas to the burner 13 is provided. The gas supply pipe 23 has a proportional valve 19 for varying the amount of gas to be supplied and an electromagnetic valve for starting / stopping gas supply. 21 are provided.
[0008]
Further, the gas water heater includes a hot-water pipe 4 connected to the additional heating return pipe 2 from a hot-water pipe 5 in the hot-water heater main body 1 downstream of the water quantity valve 62. A bath water sensor 8 for detecting a flow rate Qh flowing through the upright pipe 4 and a hot water solenoid valve 6 for starting / stopping hot water supply are provided.
The gas water heater is provided with an outside air temperature detection sensor 61 for detecting the temperature of the atmosphere in which the water heater body 1 is installed.
[0009]
On the other hand, the additional heating return pipe 2 and the additional heating forward pipe 53 are connected at their ends to a circulation adapter 55 attached to the bathtub 12, and a circulation pump P for circulating hot water in the bathtub 12, Water level sensor 10 for detecting the water level of the water, a bath temperature sensor 49 for detecting the temperature of the hot water in the bathtub 12, and the additional heating return pipe 2 via the heat exchange bypass pipe 14 via the heat exchange bypass pipe 14 without passing through the heat exchanger 7. A heat exchange three-way valve 51 is provided, which is driven by a motor M2 which can be connected to 53.
[0010]
Therefore, when the heat exchange three-way valve 51 is moved to the heat exchange position, a first circulation path is formed to connect the additional heat return pipe 2 → the heat exchanger 7 → the additional heat transfer pipe 53, thereby bypassing the heat exchange three-way valve 51. When it is moved to the position, a second circulation path is formed which connects the additional heating return pipe 2 → the heat exchange bypass pipe 14 → the additional heating forward pipe 53.
[0011]
In addition, a drain plug 60 for draining hot water in the bathtub 12 is provided on the bottom surface of the bathtub 12.
The remote controller 33 includes an operation switch 35, a setting switch 39 for setting a set temperature Ts of hot water supplied from the hot-water tap 11, a bath set temperature Tfs of hot water to be supplied to the bathtub 12, and a hot water switch to the bathtub 12. A hot water switch 36 that is turned on when the hot water is applied, a reheating switch 38 that is turned on when the hot water in the bathtub 12 is heated, an antifreeze switch 32 for performing an antifreezing operation, a set temperature Ts, and a bath set temperature Tfs. Etc. are provided on the display unit 37.
[0012]
The gas water heater further receives a proportional valve 19, a solenoid valve 21 based on detection signals (Tc, Q, Th, Tm, Ts, Tfs, etc.) from the sensors 25, 27, 45, 29 and the setting switch 39 and the like. And a control unit 31 for controlling the fan 9, the mixing valve 41 and the like.
Further, the control unit 31 can control the opening and closing operation of the drain cock 60.
[0013]
Here, when the freeze prevention switch 32 provided on the remote controller 33 is turned on, when the detection signal Tc of the incoming water temperature sensor 25 or the detection signal Tg of the outside air temperature detection sensor 61 becomes equal to or less than a predetermined value, After the control unit 31 closes the drain plug 60, the hot water solenoid valve 6 is opened, and the water supply pipe 3 → the heat exchanger 7 and the bypass pipe 43 → the hot water supply pipe 5 → the hot water supply pipe 4 → the additional heating return pipe 2 and additional heating. Hot water is applied to the bathtub 12 through the pipe 53 (the heat exchange three-way valve 51 is at the bypass position) → the circulation adapter 55.
The flow rate of the hot water is set to a predetermined flow rate (the minimum flow rate sufficient to prevent freezing), and is controlled by the water quantity valve 62 based on the detection flow rate Qh of the bath water quantity sensor 8.
Then, when the detection signal Tc of the incoming water temperature sensor 25 or the detection signal Tg of the outside air temperature detection sensor 61 exceeds a predetermined value, the hot water filling is stopped.
At this time, the integrated flow rate of hot water is stored in the control unit 31.
When the freeze prevention switch 32 is ON, the burner 13 does not burn regardless of the flow rate Qh.
[0014]
At the time of bathing, when the hot water switch 36 is pressed, hot water is applied by subtracting the integrated flow rate of hot water by the freeze prevention operation from the set value of the hot water amount set by the setting switch 39, and the set temperature is set. Refire until Tfs.
Therefore, when the detection signal Tc of the incoming water temperature sensor 25 or the detection signal Tg of the outside air temperature detection sensor 61 becomes equal to or less than a predetermined value, a predetermined flow rate from the circulation adapter 55 (the minimum flow rate sufficient to prevent freezing). Since the water is discharged, there is no need to open and close the hot water tap 11, and the water heater main body 1 can be prevented from freezing.
In addition, when bathing, the amount of water accumulated in the bathtub 12 is subtracted to fill the bath, so that water is not wasted.
[0015]
Next, a detailed freeze prevention operation will be described with reference to the flowchart of FIG.
In step S1, it is determined whether or not the antifreeze switch 32 has been turned on. If it is determined that the antifreeze switch 32 has been turned on, the water temperature is determined in advance based on the detection signal Ts of the incoming water temperature sensor 25. It is determined whether the temperature is equal to or lower than the predetermined temperature (step S2).
If it is determined in step S2 that the water temperature is equal to or lower than the predetermined temperature, the drain cock 60 provided in the bathtub 12 is closed in step S3, the hot water solenoid valve 6 is opened in step S4, and hot water is filled. Return to
At this time, the flow rate of the hot water is controlled to a predetermined flow rate (the minimum flow rate sufficient to prevent freezing).
If the antifreeze switch 32 is turned off in step S1, and if it is determined in step S2 that the water temperature has exceeded the predetermined temperature, the hot water electromagnetic valve 6 is closed in step S5 to stop hot water, and the process returns to step S1.
Note that, here, the detection signal Ts of the incoming water temperature sensor 25 is used, but the detection signal Tg of the outside air temperature detection sensor 61 may be used.
[0016]
Therefore, when the ambient temperature or the water temperature decreases, a predetermined flow rate of water is discharged from the adapter attached to the wall surface of the bathtub, and the water can be stored in the bathtub without opening and closing the hot water tap. It is possible to prevent freezing without wasting water and without trouble.
