Description

本発明は、浴室に温水ミストを噴霧するミストサウナ機能を備えた温水暖房システムの制御方法、特に、前記温水ミストを加熱生成する熱源機が能力不足状態に陥る場合の制御方法に関するものである。   The present invention relates to a control method of a hot water heating system having a mist sauna function for spraying hot water mist in a bathroom, and more particularly to a control method in a case where a heat source device that heats and generates the hot water mist falls into a state of insufficient capability.

近年、家庭用の温水暖房システムは次第に高機能化し、パネルヒータによる暖房機能や放熱マットによる床暖房機能、更には、浴室に高温ミストを噴霧するミストサウナ機能等、種々の機能が搭載されるようになった。そして、ミストサウナや床暖房時等には、共通の熱源機からの温水を利用して各機能を実現するのが一般的である。
前記ミストサウナとしては、熱源機で加熱生成された1L/分程度の温水ミスト(約70℃)を噴霧して浴室内を約40℃程度に維持する形式のものが知られているが、ミストサウナの運転開始初期には、熱源機に大きな加熱能力が要求される。即ち、ミストサウナの運転開始初期には、温水ミストの噴霧により浴室を設定温度に昇温加湿させてサウナ入浴ができる環境を整えるまで(以下、「サウナ準備作業」という。)は、浴室内が冷えているだけではなく、噴霧した温水ミストが気化熱を奪って温水自体が温度低下することもあり、サウナ準備作業を円滑に行なうためには多量の温水ミストを加熱生成する必要がある。このことから、ミストサウナの運転開始初期には、熱源機に大きな加熱能力が要求される。
従って、例えば、床暖房中にサウナ準備作業が行なわれると、更に多くの熱量が必要となり、熱源機の能力不足を招来する。その結果、従来のものでは、サウナ準備作業に長時間を要し、入浴までの待ち時間が長くなるという問題があった。そして、冬の寒い時期に於いては、前記入浴までの待ち時間が特に長くなって極めて不便なものとなる。

In recent years, household hot water heating systems have become increasingly sophisticated, and various functions such as a heating function by a panel heater, a floor heating function by a heat dissipating mat, and a mist sauna function for spraying high temperature mist in a bathroom will be installed. Became. And at the time of a mist sauna, floor heating, etc., it is common to implement | achieve each function using the hot water from a common heat source machine.
As the mist sauna, there is known a type in which a hot water mist (about 70 ° C.) of about 1 L / min generated by heating with a heat source device is sprayed to maintain the interior of the bathroom at about 40 ° C. At the beginning of sauna operation, a large heating capacity is required for the heat source machine. That is, at the beginning of the operation of the mist sauna, the interior of the bathroom is kept until an environment in which the bathroom can be heated and humidified to a set temperature by spraying hot water mist to prepare a sauna bath (hereinafter referred to as “sauna preparation work”). Not only is it cold, but the sprayed hot water mist can take away the heat of vaporization and the temperature of the hot water itself can drop, so a large amount of hot water mist needs to be generated by heating in order to perform sauna preparation work smoothly. For this reason, a large heating capacity is required for the heat source machine at the beginning of the operation of the mist sauna.
Therefore, for example, when a sauna preparation work is performed during floor heating, a larger amount of heat is required, leading to a lack of capacity of the heat source machine. As a result, the conventional one has a problem that it takes a long time for the sauna preparation work and the waiting time until bathing becomes long. In the cold winter season, the waiting time until the bathing is particularly long, which is extremely inconvenient.

Then, the circulation pump (33) is operated and the gas burner (34) is combusted, and the combustion amount of the gas burner (34) is controlled so that the temperature of the hot water detected by the hot water temperature sensor (32) is maintained at 80 ° C. . In step (ST3), the address A for specifying the output port of the microcomputer (370) necessary for floor heating control is set to 100.
Thereafter, in step (ST4), it is determined again whether any of the first to third floor heating switches (513), (523), and (533) has been turned ON. If it has been operated, step (ST5) The following floor heating control is started.

床暖房制御が始まると、ステップ(ST5)を実行し、制御装置(37)に組み込まれたマイクロコンピュータ(370)のアドレスA(ステップ(ST3)で100に設定されている。)の出力ポートを「H」にし、これにより、標準発振回路(38)を発振状態にする。すると、標準発振回路(38)から出力されるH信号とL信号が一定周期で第1AND回路(54)(55)(56)の一方の入力端子(Z)(Z)(Z)に印加される。   When the floor heating control starts, step (ST5) is executed, and the output port of the address A (set to 100 in step (ST3)) of the microcomputer (370) incorporated in the control device (37) is set. As a result, the standard oscillation circuit (38) is oscillated. Then, the H signal and L signal output from the standard oscillation circuit (38) are applied to one input terminal (Z) (Z) (Z) of the first AND circuit (54) (55) (56) at a constant cycle. The

次に、ステップ(ST6)で第1床暖房スイッチ(513)がON状態にあると判断されると、ステップ(ST7)で第1AND回路(54)の入力端子(A2)にH信号を印加する。すると、第1AND回路(54)は入力端子(Z)に交互に印加されているH・L信号に同期した信号を出力し、該同期信号によって第1開閉弁(511)が開閉する。これにより、第1放熱マット(51)が標準発熱量で発熱する。尚、第1床暖房スイッチ(513)がON操作されていない場合は、ステップ(ST8)で第1AND回路(54)の入力端子(A2)にL信号を印加し、これにより第1AND回路(54)の出力をL状態にして第1開閉弁(511)を閉弁状態に維持する。   Next, when it is determined in step (ST6) that the first floor heating switch (513) is in the ON state, an H signal is applied to the input terminal (A2) of the first AND circuit (54) in step (ST7). . Then, the first AND circuit (54) outputs a signal synchronized with the H and L signals alternately applied to the input terminal (Z), and the first on-off valve (511) is opened and closed by the synchronization signal. As a result, the first heat dissipating mat (51) generates heat with a standard heat generation amount. If the first floor heating switch (513) is not turned on, the L signal is applied to the input terminal (A2) of the first AND circuit (54) in step (ST8), thereby the first AND circuit (54). ) Is set to the L state, and the first on-off valve (511) is maintained in the closed state.

以後、上記ステップ(ST6)〜(ST8)と同様の制御を第2,第3床暖房スイッチ(521)(531)の操作に対して実行する(ステップ(ST9)〜(ST11)及び、ステップ(ST12)〜ステップ(ST14)参照)。従って、ON操作された第1〜第3床暖房スイッチ(513)(523)(533)に対応する第1〜第3開閉弁(511)(521)(531)は全て同期して開閉動作を繰り返す。   Thereafter, the same control as the above steps (ST6) to (ST8) is executed for the operation of the second and third floor heating switches (521) and (531) (steps (ST9) to (ST11) and steps ( ST12) to step (ST14)). Therefore, the first to third on-off valves (511), (521), and (531) corresponding to the first to third floor heating switches (513), (523), and (533) that have been turned ON all open and close synchronously. repeat.

次に、ステップ(ST15)で第1〜第3床暖房スイッチ(513)(523)(533)が全てOFF操作されたことが確認できると、ステップ(ST16)で第1〜第3AND回路(54)(55)(56)の入力端子(Z)(Z)(Z)にL信号を印加させる。具体的には、マイクロコンピュータ(370)のアドレスAの出力ポートを「L」にして標準発振回路(38)(制限発振回路(39)が発振状態にあるときは制限発振回路(39))を発振停止状態にし、これにより、第1〜第3開閉弁(511)(521)(531)を閉弁状態に維持する。その後、ステップ(ST17)でミストスイッチ(401)がON操作されていることが確認できると、ステップ(ST18)に進み、浴室暖房弁(203)を開弁すると共に送風ファン(202)を回転させ、更に、噴霧弁(14)を開弁させる。又、ステップ(ST18)では、ミスト用給水回路(12)に設けられた出湯温センサ(121)の検知温度が70℃になるように、ミスト加熱弁(13)の開度を制御してミスト加熱回路(36)を流れる温水の流量を調整する。尚、本実施の形態では、ステップ(ST15)→(ST17)→(ST18)の順序の制御を行なう制御部が請求項1の発明特定事項たる「同時使用検知手段」に対応する。   Next, when it is confirmed in step (ST15) that all the first to third floor heating switches (513), (523), and (533) have been turned OFF, in step (ST16), the first to third AND circuits (54 ) (55) The L signal is applied to the input terminals (Z) (Z) (Z) of (56). Specifically, the output port of address A of the microcomputer (370) is set to “L” and the standard oscillation circuit (38) (or the limited oscillation circuit (39) when the limited oscillation circuit (39) is in the oscillation state) is set. Thus, the first to third on-off valves (511), (521), and (531) are kept closed. After that, if it can be confirmed in step (ST17) that the mist switch (401) is turned on, the process proceeds to step (ST18), the bathroom heating valve (203) is opened and the blower fan (202) is rotated. Further, the spray valve (14) is opened. In step (ST18), the opening of the mist heating valve (13) is controlled so that the detected temperature of the tapping temperature sensor (121) provided in the mist water supply circuit (12) is 70 ° C. The flow rate of the hot water flowing through the heating circuit (36) is adjusted. In the present embodiment, the control unit that performs the control in the order of steps (ST15) → (ST17) → (ST18) corresponds to the “simultaneous use detecting means” as the invention-specific matter of claim 1.

次に、ステップ(ST19)〜(ST21)で浴室温センサ(42)の検知する浴室温度が40℃以上で且つ湿度センサ(43)の検知する浴室湿度が90%以上であると確認できるまで(サウナ準備作業が終了するまで)噴霧量切替弁(122)を開弁状態に維持し、これにより、サウナ準備作業が終了するまでは、二個の噴霧ノズル(10a)(10b)を利用して多量の温水ミストを浴室(4)に噴霧する。二個の噴霧ノズル(10a)(10b)を利用するのは、サウナ準備作業を迅速に行う為である。   Next, until it can be confirmed in steps (ST19) to (ST21) that the bathroom temperature detected by the bath room temperature sensor (42) is 40 ° C. or more and the bathroom humidity detected by the humidity sensor (43) is 90% or more ( The spray amount switching valve (122) is kept open until the sauna preparatory work is completed, so that two spray nozzles (10a) (10b) are used until the sauna preparatory work is completed. Spray a large amount of hot water mist on the bathroom (4). The reason for using the two spray nozzles (10a) and (10b) is to perform the sauna preparation work quickly.

次に、ステップ(ST22)で浴室暖房回路(200)に配設された戻り湯温センサ(205)の検知温度を判断する。この場合、戻り湯温センサ(205)は、暖房循環回路(30)の往き管(300)に於いて第1〜第3床暖房回路(510)(520)(530)やミスト加熱回路(36)の分岐部より更に下流側から分岐する浴室暖房回路(200)の浴暖用熱交換器(201)の下流側に配設されている。従って、戻り湯温センサ(205)の検知温度は、第1〜第3床暖房回路(510)(520)(530)の第1〜第3放熱マット(51)(52)(53)に温水供給さている状態(床暖房状態)では低くなる。又、第1〜第3床暖房回路(510)(520)(530)の使用系統数が多い程、戻り湯温センサ(205)の検知温度は低くなる。そこで、本実施の形態では、戻り湯温センサ(205)の検知温度に基づいて、熱源機(3)の能力不足レベルを判断するようにしている。具体的には、戻り湯温センサ(205)の検知温度Sが、T0>S≧T1の場合は、床暖房の能力を制限レベル1まで落とし(ステップ(ST22)(ST26)(ST27))、T1>S≧T2の場合は、床暖房の能力を制限レベル2まで落とし(ステップ(ST26)(ST28)(ST29))、T2>S≧T3の場合は、床暖房の能力を制限レベル3まで落とし(ステップ(ST28)(ST30)(ST31))、更に、T3>Sの場合は、床暖房の能力を制限レベル4まで落とす(ステップ(ST30)(ST32))。尚、本実施の形態では、T0=50℃,T1=42℃,T2=34℃,T3=26℃に夫々設定されている。   Next, in step (ST22), the temperature detected by the return hot water temperature sensor (205) disposed in the bathroom heating circuit (200) is determined. In this case, the return hot water temperature sensor (205) is connected to the first to third floor heating circuits (510) (520) (530) and the mist heating circuit (36) in the forward pipe (300) of the heating circulation circuit (30). ) Is further provided on the downstream side of the bath warming heat exchanger (201) of the bathroom heating circuit (200) branching from the downstream side. Accordingly, the temperature detected by the return hot water temperature sensor (205) is applied to the first to third heat dissipating mats (51), (52) and (53) of the first to third floor heating circuits (510), (520) and (530). It becomes low in the supplied state (floor heating state). Moreover, the detection temperature of the return hot water temperature sensor (205) becomes low, so that there are many use systems of the 1st-3rd floor heating circuit (510) (520) (530). Therefore, in the present embodiment, the capability shortage level of the heat source unit (3) is determined based on the temperature detected by the return hot water temperature sensor (205). Specifically, when the detected temperature S of the return hot water temperature sensor (205) is T0> S ≧ T1, the floor heating capacity is reduced to the limit level 1 (steps (ST22) (ST26) (ST27)), If T1> S ≧ T2, the floor heating capacity is reduced to the limit level 2 (steps (ST26) (ST28) (ST29)), and if T2> S ≧ T3, the floor heating capacity is decreased to the limit level 3. Drop (steps (ST30), (ST30), (ST31)). Further, if T3> S, the floor heating capacity is lowered to the limit level 4 (steps (ST30) (ST32)). In the present embodiment, T0 = 50 ° C., T1 = 42 ° C., T2 = 34 ° C., and T3 = 26 ° C. are set.

図3の(イ)は、図2のステップ(ST27)に記載した制限レベル1の具体的内容を示すサブルーチンであり、ステップ(ST100)でマイクロコンピュータ(370)の出力ポートを特定する為のアドレスAを101にセットする。すると、標準発振回路(38)に比べてH信号に対するL信号の時間幅の割合が大きい信号を出す制限用発振回路(39)の出力が、第1AND回路(54)(55)(56)の入力端子(Z)(Z)(Z)に印加される。これにより、第1〜第3開閉弁(511)(521)(531)に於ける閉弁時間に対する開弁時間の割合が短くなり、第1〜第3床暖房回路(510)(520)(530)への温水供給量が制限され、その分、ミストサウナ機能(浴室暖房用端末(20)を作動させつつ噴霧ノズル(10a)(10b)から温水ミストを噴霧する機能)に必要な熱量が増加する。従って、床暖房時にミストサウナ運転が開始されても十分な量の温水ミストを加熱生成でき、これにより、サウナ準備作業の所要時間が長くならず、入浴までの待ち時間が長くなるのを防止できる。   (A) in FIG. 3 is a subroutine showing the specific contents of restriction level 1 described in step (ST27) of FIG. 2, and an address for specifying the output port of the microcomputer (370) in step (ST100). Set A to 101. Then, the output of the limiting oscillation circuit (39) that outputs a signal having a larger ratio of the time width of the L signal to the H signal than the standard oscillation circuit (38) is the output of the first AND circuits (54) (55) (56). Applied to input terminals (Z) (Z) (Z). Accordingly, the ratio of the valve opening time to the valve closing time in the first to third on-off valves (511), (521), and (531) is shortened, and the first to third floor heating circuits (510) (520) ( 530) is limited in the amount of hot water supplied, and the amount of heat required for the mist sauna function (function to spray hot water mist from the spray nozzles (10a) and (10b) while operating the bathroom heating terminal (20)). To increase. Therefore, even when the mist sauna operation is started during floor heating, a sufficient amount of hot water mist can be generated by heating, thereby preventing the time required for the sauna preparation work from being increased and preventing the waiting time until bathing from being increased. .

図3の(ロ)は、図2のステップ(ST29)に記載した制限レベル2の具体的内容を示すサブルーチンであり、ステップ(ST101)に於いて、制御装置(37)の出力端子(X1)(X2)(X3)からの信号により第1〜第3床暖房回路(510)(520)(530)の第1〜第3絞り弁(512)(522)(532)を半開状態に絞る。これにより、制限レベル1に比べて更に熱源機(3)が能力不足に陥る条件下(戻り湯温センサ(205)の検知温度SがT1未満でT2以上の条件下)では、第1〜第3絞り弁(512)(522)(532)により、各第1〜第3床暖房回路(510)(520)(530)の温水流量を絞り、これにより、第1〜第3床暖房回路(510)(520)(530)への温水供給量を「制限レベル1」より更に制限する。従って、「制限レベル1」に比べ、ミストサウナ機能に必要な熱量が更に増加する。   FIG. 3 (b) is a subroutine showing the specific contents of restriction level 2 described in step (ST29) of FIG. 2, and in step (ST101), the output terminal (X1) of the control device (37). The first to third throttle valves (512), (522), and (532) of the first to third floor heating circuits (510), (520), and (530) are throttled to a half-open state by signals from (X2) and (X3). As a result, under conditions where the heat source device (3) is further incapacitated compared to the limit level 1 (under the condition that the detection temperature S of the return hot water temperature sensor (205) is less than T1 and greater than or equal to T2), the first to first The three throttle valves (512), (522), and (532) throttle the hot water flow rates of the first to third floor heating circuits (510), (520), and (530), and thereby the first to third floor heating circuits ( The hot water supply amount to 510, 520, and 530 is further restricted from “restriction level 1”. Therefore, the amount of heat required for the mist sauna function is further increased as compared with “restricted level 1”.

図3の(ハ)、図2のステップ(ST31)に記載した制限レベル3の具体的内容を示すサブルーチンであり、ステップ(ST102)に於いて、制御装置(37)の出力端子(X3)からの信号により第3床暖房回路(530)の第3絞り弁(532)を全閉状態にする。これにより、制限レベル2に比べて更に熱源機(3)が能力不足に陥る条件下(戻り湯温センサ(205)の検知温度SがT2未満でT3以上の条件下)では、第3床暖房回路(530)を非通水状態になる。この状態では、第1〜第3床暖房回路(510)(520)(530)への温水供給量が「制限レベル2」より更に制限されるようになっており、これにより、「制限レベル2」に比べ、ミストサウナ機能に必要な熱量を更に増加させ得るようにしている。   3 is a subroutine showing the specific contents of restriction level 3 described in step (ST31) of FIG. 3 and step (ST31) of FIG. 2, and in step (ST102), from the output terminal (X3) of the control device (37). The third throttle valve (532) of the third floor heating circuit (530) is fully closed by this signal. As a result, the third floor heating is performed under the condition that the heat source device (3) is further incapacitated compared to the limit level 2 (under the condition that the detection temperature S of the return hot water temperature sensor (205) is lower than T2 and equal to or higher than T3). The circuit (530) becomes non-water-permeable. In this state, the amount of hot water supplied to the first to third floor heating circuits (510), (520), and (530) is further restricted from “restriction level 2”. The amount of heat required for the mist sauna function can be further increased as compared to "."

図3の(ニ)は、図2のステップ(ST32)に記載した制限レベル4の具体的内容を示すサブルーチンであり、ステップ(ST103)に於いて、浴室温度が40℃以上で且つ浴室湿度が90%以上に上昇したことが確認できるまで(サウナ準備作業が終了するまで)は、マイクロコンピュータ(370)のアドレスAの出力ポートを「L」にして標準発振回路(38)(制限発振回路(39)が発振状態にあるときは制限発振回路(39))を発振停止状態にし、これにより、第1〜第3AND回路(54)(55)(56)の入力端子(Z)(Z)(Z)にL信号を印加して第1〜第3床暖房回路(510)(520)(530)の第1〜第3絞り弁(512)(522)(532)を閉じる(ステップ(ST104))。これにより、熱源機(3)が更に能力不足に陥る条件下(戻り湯温センサ(205)の検知温度SがT3未満の条件下)では、全ての床暖房回路第1〜第3床暖房回路(510)(520)(530)に配設された第1〜第3絞り弁(512)(522)(532)が全閉状態になるから、ミストサウナ機能に必要な熱量が制限ベレル3に比べて更に増加する。一方、浴室温度が40℃以上で且つ浴室湿度が90%以上に上昇したことが確認できると(サウナ準備作業が終了すると)、ステップ(ST105)が実行され、マイクロコンピュータ(370)のアドレスAの出力ポートを「H」にして標準発振回路(38)又は制限発振回路(39)を発振させる。   (D) in FIG. 3 is a subroutine showing the specific contents of the restriction level 4 described in step (ST32) of FIG. 2. In step (ST103), the bathroom temperature is 40 ° C. or more and the bathroom humidity is Until it can be confirmed that it has risen to 90% or more (until the sauna preparation work is completed), the output port of address A of the microcomputer (370) is set to “L” and the standard oscillation circuit (38) (limited oscillation circuit ( 39) is in the oscillation state, the limited oscillation circuit (39)) is set in the oscillation stop state, and thereby the input terminals (Z) (Z) (1) of the first to third AND circuits (54) (55) (56) Z) is applied with an L signal to close the first to third throttle valves 512, 522 and 532 of the first to third floor heating circuits 510, 520 and 530 (step (ST104)). ). As a result, under the condition that the heat source device (3) further falls in capacity (under the condition that the detection temperature S of the return hot water temperature sensor (205) is less than T3), all the floor heating circuits 1 to 3 are heated. Since the first to third throttle valves (512), (522), and (532) disposed in (510), (520), and (530) are fully closed, the amount of heat required for the mist sauna function is transferred to the restricted bereel 3 Compared to the increase. On the other hand, if it can be confirmed that the bathroom temperature is 40 ° C. or higher and the bathroom humidity is increased to 90% or more (when the sauna preparation work is completed), step (ST105) is executed, and the address A of the microcomputer (370) is The output port is set to “H” to oscillate the standard oscillation circuit (38) or the limited oscillation circuit (39).

尚、図2のフローチャートに於いて、ステップ(ST22)を実行したときに、浴室暖房回路(200)に設けられた戻り湯温センサ(205)の検知温度SがT0以上である場合は、熱源機(3)が能力不足に陥っていないと判断し、かかる場合は、ステップ(ST23)でマイクロコンピュータ(370)の出力ポートを特定するアドレスAを100にし、これにより、標準発振回路(38)の発振信号を第1AND回路(54)(55)(56)の入力端子(Z)(Z)(Z)に印加させると共に、制御装置(37)の出力ポート(X1)(X2)(X3)からの信号で第1〜第3床暖房回路(510)(520)(530)に配設された第1〜第3絞り弁(512)(522)(532)を全開状態に維持する。
又、ステップ(ST24)でミストスイッチ(401)のOFF操作が確認できると、ステップ(ST25)で浴室暖房弁(203)、ミスト加熱弁(13)、噴霧弁(14)を閉じると共に送風ファン(202)を停止させて運転停止状態にする。又、ステップ(ST4)に於いて第1〜第3床暖房スイッチ(513)(523)(533)の何れのON操作も確認されない場合は、最初のステップ(ST1)に制御が戻される。
In the flowchart of FIG. 2, when the detected temperature S of the return hot water temperature sensor (205) provided in the bathroom heating circuit (200) is equal to or higher than T0 when step (ST22) is executed, the heat source When the machine (3) determines that the capacity is not insufficient, in such a case, the address A for identifying the output port of the microcomputer (370) is set to 100 in step (ST23), thereby the standard oscillation circuit (38). Is applied to the input terminals (Z), (Z), and (Z) of the first AND circuits (54), (55), and (56), and the output ports (X1), (X2), and (X3) of the control device (37). The first to third throttle valves (512), (522), and (532) disposed in the first to third floor heating circuits (510), (520), and (530) are maintained in a fully opened state by a signal from
If the mist switch (401) is turned off in step (ST24), the bathroom heating valve (203), the mist heating valve (13), and the spray valve (14) are closed in step (ST25) and the blower fan ( 202) to stop operation. If none of the first to third floor heating switches (513), (523), and (533) is turned on in step (ST4), the control is returned to the first step (ST1).

In the above embodiment, it is determined whether or not the heat source machine (3) is in a condition where the capacity is insufficient based on the temperature detected by the return hot water temperature sensor (205) provided in the bathroom heating circuit (200). It may be determined whether or not the heat source machine (3) is in a condition that the capacity is insufficient based on the number of systems used in the first to third floor heating circuits (510), (520), and (530).

In the above embodiment, it is determined whether or not the heat source machine (3) is in a condition where the capacity is insufficient based on the temperature detected by the return hot water temperature sensor (205) provided in the bathroom heating circuit (200). Based on the output of the hot water temperature sensor (32) for detecting the hot water temperature of the machine (3), the condition for the shortage of capacity may be determined. Specifically, if the temperature detected by the tapping temperature sensor (32) is 80 ° C., it is determined that the capacity is not insufficient.
