Description

本発明は、浴室用ミスト装置、特に、浴室内において湯水をミスト状に噴霧させてサウナ効果を得られるようにする浴室用ミスト装置に関する。   The present invention relates to a bathroom mist device, and more particularly, to a bathroom mist device in which a sauna effect is obtained by spraying hot and cold water in a mist form in a bathroom.

近年、加熱された湯水を、浴室に設置されたミスト噴霧部からミスト状に噴霧させてサウナ効果を高める浴室用ミスト装置が、浴室暖房装置と共に普及しつつある。
前記ミスト装置に、台所や洗面所等に給湯する給湯用の温水を分岐させてそのまま使用した場合、それがバーナを燃焼させるために熱交換器に通流させなければならない必要最少限の水量、所謂、最低作動水量であったとしても、ミストの噴霧に適する温水量としては多量であることから、これをミスト噴霧部から噴霧させると、ミスト粒径が大きくなってしまい、使用者に不快感を与えてしまうといった不都合があった。又、ミスト噴霧部に供給する温水量を少なくするために、前記温水の一部を排出することも考えられるが、これでは資源の無駄になり、ランニングコストを増大させる不都合があった(特許文献1)。
このような不都合を防止するために、図に示すように、ミスト噴霧部(1)を、水道水を供給するミスト用給水回路(11)の下流端に設け、ミスト噴霧部(1)に至る流路の途中に、液々熱交換器(10)を介設し、暖房回路を通じて供給される熱媒体で前記水道水を加熱する構成のものが知られている(特許文献2、3)。
In recent years, bathroom mist devices that increase the sauna effect by spraying heated hot water in a mist form from a mist spraying section installed in the bathroom are becoming popular with bathroom heating devices.
When the hot water for hot water supplied to the kitchen or washroom is branched and used as it is in the mist device, the minimum amount of water that must be passed through the heat exchanger to burn the burner, Even if it is the so-called minimum working water amount, the amount of warm water suitable for spraying mist is large, so if this is sprayed from the mist spraying section, the mist particle size becomes large and the user feels uncomfortable. There was an inconvenience such as giving. Further, in order to reduce the amount of hot water supplied to the mist spraying part, it is conceivable to discharge a part of the hot water, but this is a waste of resources and has a disadvantage of increasing running cost (Patent Document). 1).
In order to prevent such inconvenience, as shown in FIG. 4 , the mist spraying section (1) is provided at the downstream end of the water supply circuit for mist (11) for supplying tap water, and the mist spraying section (1) is provided. There is known a configuration in which a liquid-liquid heat exchanger (10) is provided in the middle of the flow path to reach the tap water with a heat medium supplied through a heating circuit (Patent Documents 2 and 3). .

このものでは、浴室(4)に浴室暖房装置(20)が設置されていると共に、熱源機として浴室暖房用の熱源部(23)を内蔵する給湯装置(2)が屋外に設置されており、前記暖房用熱源部(23)と浴室暖房用装置(20)との間を循環する循環加熱回路(21)から分岐された分岐循環回路(22)を介して、前記液々熱交換器(10)に前記熱媒体としての温水が供給されている。これにより、前記液々熱交換器(10)を介して、前記ミスト用給水回路(11)内の水が温められるように設定されている。
尚、前記液々熱交換器(10)は、高効率であるプレート式熱交換器が好適であり、伝熱プレート(10a)の両側にミスト用給水回路(11)側の水と分岐循環回路(22)側の温水が交互にながれることにより、伝熱プレート(10a)を介して熱交換される。
In this, the bathroom heating device (20) is installed in the bathroom (4), and the hot water supply device (2) with a built-in heat source part (23) for bathroom heating is installed outdoors as a heat source, Through the branch circulation circuit (22) branched from the circulation heating circuit (21) circulating between the heating heat source section (23) and the bathroom heating device (20), the liquid heat exchanger (10 ) Is supplied with hot water as the heat medium. Accordingly, the water in the water supply circuit for mist (11) is set to be warmed through the liquid heat exchanger (10).
The liquid heat exchanger (10) is preferably a plate-type heat exchanger with high efficiency, and water on the mist water supply circuit (11) side and branch circulation circuit on both sides of the heat transfer plate (10a). When the hot water on the (22) side flows alternately, heat is exchanged via the heat transfer plate (10a).

この場合、前記ミスト用給水回路(11)へ通水させる水量は、前記最低作動水量の制約を受けることがないから、ミスト噴霧部(1)から噴霧させるのに適した所定量に設定することができる。よって、液々熱交換器(10)を介して加熱された前記ミスト用給水回路(11)の温水をミスト噴霧部(1)から適度なミスト粒径で浴室(4)内に噴霧することができる。
前記した従来のミスト装置では、液々熱交換器(10)の下流側に、前記ミスト用給水回路(11)を開閉する開閉弁としての第1、第2電磁弁(31)(32)と、これら第1、第2電磁弁(31)(32)の間から分岐された配水管(12)の自動排水弁(30)が設けられており、液々熱交換器(10)の上流側には、ミスト用給水回路(11)内の水圧を調整する減圧弁(36)が設けられている。又、循環加熱回路(21)から分岐循環回路(22)に分岐される分岐部には、循環加熱回路(21)から分岐循環回路(22)へ送られる循環温水の流量を調節する流量制御弁(33)と、前記循環温水の温度を検知する熱交換器用サーミスタ(34)が搭載されている。
In this case, the amount of water to be passed through the water supply circuit for mist (11) is not restricted by the minimum amount of working water, so it should be set to a predetermined amount suitable for spraying from the mist spraying section (1). Can do. Therefore, it is possible to spray the warm water of the water supply circuit for mist (11) heated through the liquid heat exchanger (10) from the mist spraying part (1) into the bathroom (4) with an appropriate mist particle size. it can.
In the above-described conventional mist device, the first and second solenoid valves (31), (32) as opening / closing valves for opening / closing the water supply circuit (11) for the mist are provided downstream of the liquid heat exchanger (10). An automatic drain valve (30) of the water pipe (12) branched from between the first and second solenoid valves (31) and (32) is provided upstream of the liquid heat exchanger (10). Is provided with a pressure reducing valve (36) for adjusting the water pressure in the water supply circuit for mist (11). In addition, a flow control valve for adjusting the flow rate of the circulating hot water sent from the circulation heating circuit (21) to the branch circulation circuit (22) is provided at the branch portion branched from the circulation heating circuit (21) to the branch circulation circuit (22). And a heat exchanger thermistor (34) for detecting the temperature of the circulating hot water.

ミスト装置の運転開始時においては、流量制御弁(33)を全開にして、循環加熱回路(21)から前記分岐循環回路(22)へ温水を送り込み、循環加熱回路(21)内の温水と共に分岐循環回路(22)内の温水を循環させることにより循環温水を適温になるまで温める。前記熱交換器用サーミスタ(34)によって循環温水が充分温まったと検知されると、第1電磁弁(31)は閉じた状態で、第2電磁弁(32)と自動排水弁(30)が開き、液々熱交換器(10)による熱交換が開始される。前記液々熱交換器(10)の下流側に設けられているミストサーミスタ(35)によって、ミスト用給水回路(11)内の温水の温度を検知し、ミスト用設定温度以下の温水は、排水管(12)から排出される。前記ミストサーミスタ(35)によって、ミスト用給水回路(11)内の温水の温度が安定したことが検知されると、前記自動排水弁(30)が閉弁すると共に、第1電磁弁(31)が開弁し、ミスト噴霧部(1)からミストが浴室(4)内に噴霧されることとなる。これにより、ミスト装置の運転初期から、冷水ではなく適温の温水をミスト噴霧部(1)から噴霧することが可能となる。   At the start of operation of the mist device, the flow rate control valve (33) is fully opened, hot water is sent from the circulation heating circuit (21) to the branch circulation circuit (22), and is branched together with the hot water in the circulation heating circuit (21). By circulating the hot water in the circulation circuit (22), the hot water is warmed to an appropriate temperature. When it is detected by the heat exchanger thermistor (34) that the circulating hot water is sufficiently warm, the second solenoid valve (32) and the automatic drain valve (30) are opened with the first solenoid valve (31) closed, Heat exchange by the liquid heat exchanger (10) is started. The temperature of hot water in the water supply circuit for mist (11) is detected by the mist thermistor (35) provided on the downstream side of the liquid-to-liquid heat exchanger (10). Discharged from the tube (12). When the mist thermistor (35) detects that the temperature of the hot water in the mist water supply circuit (11) is stable, the automatic drain valve (30) is closed and the first electromagnetic valve (31) Is opened, and mist is sprayed from the mist spraying section (1) into the bathroom (4). Thereby, it is possible to spray hot water having an appropriate temperature instead of cold water from the mist spraying section (1) from the initial operation of the mist device.

ミスト装置の運転終了後には、第2電磁弁(32)を閉じた状態で、前記第1電磁弁(31)と自動排水弁(30)の両方を開けておくと、第2電磁弁(32)からミスト噴霧部(1)までのミスト用温水供給路(13)内の残留水は自然落下によって排水管(12)から排水される。これにより、ミスト用温水供給路(13)内に残存した湯水に雑菌が繁殖して汚水となり、この汚水が、次回のミスト噴霧時にミスト噴霧部(1)から噴霧する不都合を防止している。   After the operation of the mist device is completed, if both the first solenoid valve (31) and the automatic drain valve (30) are opened with the second solenoid valve (32) closed, the second solenoid valve (32 ) To the mist spraying section (1), residual water in the mist hot water supply channel (13) is drained from the drain pipe (12) by natural fall. Thus, various bacteria are propagated in the hot water remaining in the hot water supply channel (13) for mist to become sewage, and this sewage prevents inconvenience of spraying from the mist spraying section (1) at the next mist spraying.

しかしながら、一般的には、前記暖房用の循環温水に、プロピレングリコール等の不凍液が投入されており、これが前記液々熱交換器(10)に供給される。液々熱交換器(10)に、例えば、上記したプレート式熱交換器を使用している場合、前記不凍液が混入された分岐循環回路(22)側の温水とミスト用給水回路(11)を通じて供給される水道水とが、前記伝熱プレート(10a)の両側に交互に流れるように構成されている。よって、万一、前記伝熱プレート(10a)に穴があく等して、前記不凍液混入の温水が、ミスト用給水回路(11)内に混入してしまった場合、前記ミスト用給水回路(11)が何らかの条件で負圧になると、前記不凍液がミスト用給水回路(11)を逆流する。前記循環温水は、永年にわたって循環使用するものであるから汚水となっており、これが逆流しては、上流側である上水道を汚染してしまうといった問題がある。   However, generally, an antifreeze liquid such as propylene glycol is introduced into the circulating hot water for heating, and this is supplied to the liquid heat exchanger (10). For example, when the plate heat exchanger described above is used as the liquid heat exchanger (10), the water and mist water supply circuit (11) through the branch circulation circuit (22) side in which the antifreeze liquid is mixed are used. The supplied tap water is configured to alternately flow on both sides of the heat transfer plate (10a). Therefore, in the unlikely event that the heat transfer plate (10a) has a hole or the like and the warm water mixed with the antifreeze liquid has entered the mist water supply circuit (11), the mist water supply circuit (11 ) Becomes negative pressure under some conditions, the antifreeze liquid flows backward through the water supply circuit for mist (11). Since the circulating hot water is circulated and used for many years, it becomes sewage. If the circulating hot water flows backward, there is a problem that the upstream water supply is contaminated.

本発明はかかる点に鑑みて成されたもので、『熱源機から循環加熱回路を通じて供給される熱媒体で、ミスト用給水回路を通じて供給される水を加熱する液々熱交換器と、前記液々熱交換器で加熱された前記ミスト用給水回路内の温水を浴室内へ噴霧するミスト噴霧部とが備えられた浴室用ミスト装置』において、前記循環加熱回路内の汚水が、ミスト用給水回路に混入されても、汚染された水がミスト用給水回路内を上流側へ逆流しないようにすることを課題とする。   The present invention has been made in view of such a point, and “a liquid medium heat exchanger supplied from a heat source device through a circulation heating circuit and heating water supplied through a water supply circuit for mist; In the mist apparatus for bathroom provided with a mist spraying section for spraying hot water in the water supply circuit for mist heated by a heat exchanger into the bathroom, the sewage in the circulation heating circuit is supplied to the water supply circuit for mist. It is an object of the present invention to prevent contaminated water from flowing backward in the mist water supply circuit to the upstream side even if mixed into the mist.

[請求項1に係る発明]
上記課題を解決する為の請求項1に係る発明の技術的手段は、『前記ミスト用給水回路の前記液々熱交換器の上流側に、前記ミスト用給水回路内の逆流を防止する逆流を防止する逆止弁を設け、
前記液々熱交換器の下流側に、前記ミスト用給水回路を開閉する開閉弁としての第1開閉弁及び第2開閉弁を直列に設け、且つ第1開閉弁と第2開閉弁の間に排水弁を設け、
前記熱源機の作動が開始され前記液々熱交換器へ前記熱媒体の供給が開始されると同時に上流側の第2開閉弁及び排水弁を開弁してミスト用給水回路への水の供給を開始し排水弁からミスト用給水回路内の湯水を排出し、ミスト用給水回路の温度がミスト噴霧用の設定温度以上になると下流側の第1開閉弁を開弁すると共に排水弁を閉弁してミスト噴霧部から温水を噴霧開始するように設定されている』ことである。
上記技術的手段は次のように作用する。
循環加熱回路は、例えば、床暖房装置や浴室暖房装置等の暖房用端末と、暖房用熱源部との間に接続されており、前記循環加熱回路内を循環する温水(循環温水)が、熱媒体として液々熱交換器の一次側に供給され、二次側のミスト用給水回路を通じて供給される水が加熱される。万一、液々熱交換器の破損等によって、前記熱交換器内で、前記循環温水が前記ミスト用給水回路内に混入することがあったとしても、前記液々熱交換器の上流側には逆止弁が設けられているから、前記循環温水がミスト用給水回路を上流側に逆流することがない。
[Invention of Claim 1]
The technical means of the invention according to claim 1 for solving the above-mentioned problem is as follows: "A reverse flow that prevents a reverse flow in the water supply circuit for the mist is provided upstream of the liquid heat exchanger of the water supply circuit for the mist. A check valve to prevent
A first on-off valve and a second on-off valve as an on-off valve for opening and closing the water supply circuit for mist are provided in series on the downstream side of the liquid heat exchanger , and between the first on-off valve and the second on-off valve. A drain valve,
Supply of water to the water supply circuit for mist by opening the second on-off valve and the drain valve on the upstream side at the same time as the operation of the heat source apparatus is started and the supply of the heat medium to the liquid-to-liquid heat exchanger is started. The hot water in the mist water supply circuit is discharged from the drain valve, and when the temperature of the mist water circuit exceeds the set temperature for mist spraying, the first on-off valve on the downstream side is opened and the drain valve is closed. It is set to start spraying hot water from the mist spraying section .
The technical means operates as follows.
The circulation heating circuit is connected, for example, between a heating terminal such as a floor heating device or a bathroom heating device and a heating heat source unit, and hot water (circulation hot water) circulating in the circulation heating circuit is heated. Water supplied as a medium to the primary side of the liquid-to-liquid heat exchanger and supplied through the water supply circuit for mist on the secondary side is heated. Even if the circulating hot water may be mixed in the water supply circuit for mist in the heat exchanger due to breakage of the liquid heat exchanger, etc., it will be upstream of the liquid heat exchanger. Since the check valve is provided, the circulating hot water does not flow back to the mist water supply circuit upstream.

ところで、前記開閉弁を閉じた状態においては、前記開閉弁と前記逆止弁との間には、閉塞された空間が形成されることとなり、その部分が液々熱交換器によって加熱されると、ミスト用給水回路における前記閉塞空間内の温水は体積膨張し、その影響で前記開閉弁に過剰な圧力がかかり、前記開閉弁が開かずに噴霧不良を起こすといった不都合が考えられる。又、ミスト用給水回路内に温水が通水していない場合でも、前記閉塞空間内の気体が体積膨張するため同じ現象が起こる。 Incidentally, in the closed state of the said opening and closing valve, between said opening and closing valve the check valve becomes a possible closed space is formed, the portion thereof Ru is heated by a liquid-liquid heat exchanger The hot water in the closed space in the water supply circuit for mist expands in volume, which causes an inconvenience that excessive pressure is applied to the on-off valve, causing spray failure without opening the on-off valve. Further, even when warm water does not flow through the water supply circuit for mist, the same phenomenon occurs because the gas in the closed space expands in volume.

そこで、請求項1に係る発明の技術的手段は、前記熱源機の作動が開始され前記液々熱交換器へ前記熱媒体の供給が開始されると同時に上流側の第2開閉弁及び排水弁を開弁してミスト用給水回路への水の供給を開始し排水弁からミスト用給水回路内の湯水を排出するように設定されている。これにより、前記開閉弁(第1開閉弁及び第2開閉弁)と前記逆止弁間の空間内の温水が前記液々熱交換器によって加熱されることとなるが、前記熱源機の作動が開始され前記液々熱交換器へ前記熱媒体の供給が開始されると同時に上流側の第2開閉弁及び排水弁を開弁させるようにしたから、前記空間は下流側へ開放することとなり、前記第2開閉弁と前記逆止弁との間の内圧が高まることはない。
そして、ミスト用給水回路の温度がミスト噴霧用の設定温度以上になると下流側の第1開閉弁を開弁すると共に排水弁を閉弁してミスト噴霧部から温水を噴霧開始するように設定されている。これにより、ミスト装置の運転初期から、冷水ではなく適温の温水をミスト噴霧部から噴霧することが可能となる。
Therefore, the technical means of the invention according to claim 1 is that the operation of the heat source unit is started and the supply of the heat medium to the liquid heat exchanger is started at the same time as the second on-off valve and drain valve on the upstream side. Is set so that the water supply to the mist water supply circuit is started and the hot water in the mist water supply circuit is discharged from the drain valve. Thereby, the hot water in the space between the on-off valve (the first on-off valve and the second on-off valve) and the check valve is heated by the liquid heat exchanger, but the operation of the heat source machine is Since the second on-off valve and the drain valve on the upstream side are opened at the same time as the supply of the heat medium to the liquid heat exchanger is started, the space is opened to the downstream side, The internal pressure between the second on-off valve and the check valve does not increase.
When the temperature of the water supply circuit for mist becomes equal to or higher than the set temperature for mist spraying, the first on-off valve on the downstream side is opened and the drain valve is closed to start spraying hot water from the mist spraying section. ing. Thereby, it is possible to spray hot water having an appropriate temperature from the mist spraying section instead of cold water from the initial operation of the mist device.

[請求項に係る発明]
請求項に係る発明の技術的手段は、請求項1の浴室用ミスト装置において、『前記逆止弁よりも下流側で且つ前記開閉弁よりも上流側に、前記ミスト用給水回路の内圧を逃がす過圧逃がし手段を設けた』ものであり、前記開閉弁と前記逆止弁との間に液々熱交換器が設けられ前記開閉弁と前記逆止弁間の空間内の温水が前記液々熱交換器によって加熱されることとなるが、前記開閉弁と前記逆止弁間の空間内の圧力は、過圧逃がし手段によって逃がす構成としたから、前記開閉弁と前記逆止弁との間の内圧が高まることはない。
[Invention of Claim 2 ]
Technical means of the invention according to claim 2 is the bathroom mist device according to claim 1, upstream of and the on-off valve in the downstream side of the "front Kigyakutomeben, the internal pressure of the mist water supply circuit are those "overpressure relief is provided with means for releasing, liquid-liquid heat exchanger is provided between the check valve and the on-off valve, the hot water in the space between said on-off valve the check valve Although it is heated by the liquid heat exchanger, since the pressure in the space between the on-off valve and the check valve is released by the overpressure release means, the on-off valve and the check valve The internal pressure between is not increased.

本発明は次の特有の効果を有する。
請求項1に係る発明では、ミスト用給水回路の逆止弁を、液々熱交換器の上流側に設けて、ミスト用給水回路の上流である上水道への逆流を防止できるようにしたから、たとえ、液々熱交換器内で、循環回路内の汚水である循環温水がミスト用給水回路内に混入するようなことがあっても、前記上水が汚水される不都合がない。
また、ミスト用給水回路の逆止弁を、液々熱交換器の上流側に設けて、前記液々熱交換器によって前記ミスト用給水回路が加熱されても、前記開閉弁に過剰な圧力がかからないようにしたから、ミスト装置の運転開始時に、前記開閉弁が開かないといった不都合はない。よって、ミスト装置の使い勝手が良くなる上に、ミスト噴霧部からの噴霧不良を防止することができる。ミスト用給水回路は、上記したようなミスト装置の運転初期のウォームアップ時に、前記液々熱交換器によって加熱されることとなるが、この場合でも、開閉弁の開操作に支障を来たすことはない。
The present invention has the following specific effects.
In the invention according to claim 1, since the check valve of the water supply circuit for mist is provided on the upstream side of the liquid heat exchanger, it is possible to prevent the backflow to the water supply upstream of the water supply circuit for mist. Even if circulating hot water, which is sewage in the circulation circuit, is mixed in the mist water supply circuit in the liquid heat exchanger, there is no inconvenience that the clean water is sewed.
In addition , a check valve for the water supply circuit for mist is provided upstream of the liquid-liquid heat exchanger, and even if the water supply circuit for mist is heated by the liquid-liquid heat exchanger, excessive pressure is applied to the on-off valve.

前記循環加熱回路(21)には、分岐循環回路(22)が分岐されており、前記暖房用熱源部(23)のバーナの燃焼により加熱された温水が前記循環加熱回路(21)内を循環すると同時に分岐循環回路(22)内を循環することにより、前記分岐循環回路(22)を循環する温水が熱媒体として、液々熱交換器(10)の一次側に供給されることとなる。
前記液々熱交換器(10)は、複数並列された伝熱プレート(10a)間に流路が構成されると共に、分岐循環回路(22)を循環する温水と、二次側のミスト用給水回路(11)を流れる水とが交互に流れるように構成することにより、前記伝熱プレート(10a)を介して熱交換が行えるようにしたプレート式熱交換器である。
これにより、前記ミスト用給水回路(11)を通じて供給される水は、液々熱交換器(10)を介して、分岐循環回路(22)を循環する温水によって加熱される。
尚、上記した従来のミスト装置の回路と同様に、循環加熱回路(21)から分岐循環回路(22)への分岐部分には、流量制御弁(33)とサーミスタ(34)が設けられている。又、ミスト用給水回路(11)内における液々熱交換器(10)の下流側にはミストサーミスタ(35)が設けられていると共に、上流側には、減圧弁(36)及び逆止弁(37)が設けられている。
A branch circulation circuit (22) is branched to the circulation heating circuit (21), and hot water heated by combustion of the burner of the heating heat source section (23) circulates in the circulation heating circuit (21). At the same time, by circulating in the branch circuit (22), the hot water circulating in the branch circuit (22) is supplied to the primary side of the liquid heat exchanger (10) as a heat medium.
The liquid-to-liquid heat exchanger (10) has a flow path formed between a plurality of heat transfer plates (10a) arranged in parallel, hot water circulating in the branch circulation circuit (22), and water supply for mist on the secondary side The plate heat exchanger is configured such that heat can be exchanged through the heat transfer plate (10a) by being configured such that water flowing in the circuit (11) flows alternately.
Thereby, the water supplied through the water supply circuit for mist (11) is heated by the hot water circulating through the branch circulation circuit (22) via the liquid-liquid heat exchanger (10).
As with the conventional mist circuit described above, the flow control valve (33) and the thermistor (34) are provided at the branch from the circulation heating circuit (21) to the branch circulation circuit (22). . A mist thermistor (35) is provided downstream of the liquid heat exchanger (10) in the mist water supply circuit (11), and a pressure reducing valve (36) and a check valve are provided upstream. (37) is provided.

そして、参考例のミスト回路では、前記ミスト用給水回路(11)を開閉する開閉弁としての電磁弁(3)を、液々熱交換器(10)の上流側に設けていると共に、前記液々熱交換器(10)の上流側で且つ前記電磁弁(3)の下流側から分岐された排水管(12)に自動排水弁(30)を設けて、ミスト用給水回路(11)内の温水を排水管(12)から外部に排出できるように設定している。
上記浴室暖房装置(20)及びミスト噴霧部(1)の運転は、遠隔操作可能に設定されており、図示しないが、リモコンのミスト運転スイッチをON操作すると、暖房用熱源部(23)が作動すると同時に、流量制御弁(33)が設定開度に維持され、循環加熱回路(21)と分岐循環回路(22)内の温水が循環する。尚、前記温水の温度が、液々熱交換器(10)で、ミスト用給水回路(11)の水を有効に加熱し得る設定温度以上であるかはサーミスタ(34)によって検知され、加熱し得る設定温度以上であれば、電磁弁(3)が開弁して、ミスト用給水回路(11)内に水道水が通水される。このとき、自動排水弁(30)は閉弁されている。
In the mist circuit of the reference example , an electromagnetic valve (3) as an on-off valve for opening and closing the mist water supply circuit (11) is provided on the upstream side of the liquid heat exchanger (10), and the liquid An automatic drain valve (30) is provided in the drain pipe (12) branched from the upstream side of the heat exchanger (10) and from the downstream side of the solenoid valve (3), and the mist water supply circuit (11) The hot water is set to be discharged from the drain pipe (12).
The operation of the bathroom heating device (20) and the mist spraying section (1) is set to be remotely operable, and although not shown, when the mist operation switch of the remote control is turned ON, the heating heat source section (23) is activated. At the same time, the flow control valve (33) is maintained at the set opening, and the hot water in the circulation heating circuit (21) and the branch circulation circuit (22) circulates. Whether the temperature of the hot water is equal to or higher than a set temperature at which the water in the water supply circuit for mist (11) can be effectively heated by the liquid-to-liquid heat exchanger (10) is detected by the thermistor (34) and heated. If it is above the set temperature to be obtained, the solenoid valve (3) is opened, and tap water is passed through the water supply circuit for mist (11). At this time, the automatic drain valve (30) is closed.

ミスト用給水回路(11)へ通水された水は、液々熱交換器(10)を通過する際に加熱され、前記ミスト噴霧部(1)から浴室(4)へミスト状に噴霧することができる。尚、ミスト用給水回路(11)内の水圧が減圧弁(36)によって一定に保持され、且つ、ミストサーミスタ(35)での検出温度がミスト噴霧用設定温度に保持されるように、流量制御弁(33)で分岐循環回路(22)に送り込む流量が調整される。
そして、前記ミスト運転スイッチをOFFにすると、電磁弁(3)が閉弁し且つ自動排水弁(30)が開弁すると共に、暖房用熱源部(23)が停止する。前記電磁弁(3)及び自動排水弁(30)は液々熱交換器(10)よりも上流側に設けられていると共に、ミスト噴霧部(1)よりも低い位置に配設されているものであるから、ミスト用給水回路(11)内の残留水は自然落下により、ミスト用給水回路(11)内を逆流し、前記電磁弁(3)で塞き止められると共に、自動排水弁(30)を介して、排水管(12)から外部へ排出される。これにより、使用後のミスト用給水回路(11)には、電磁弁(3)の下流側においては、湯水が残留することはない。よって、次回の使用時に、ミスト噴霧部(1)から残留水を初期排水する必要がなく、ランニングコストを節約することができる。
The water passed through the water supply circuit for mist (11) is heated when passing through the liquid heat exchanger (10) and sprayed from the mist spraying section (1) to the bathroom (4) in a mist form. Can do. The flow rate control is performed so that the water pressure in the water supply circuit for mist (11) is held constant by the pressure reducing valve (36) and the temperature detected by the mist thermistor (35) is held at the set temperature for mist spraying. The flow rate fed to the branch circuit (22) is adjusted by the valve (33).
When the mist operation switch is turned off, the solenoid valve (3) is closed and the automatic drain valve (30) is opened, and the heating heat source (23) is stopped. The solenoid valve (3) and the automatic drain valve (30) are provided on the upstream side of the liquid heat exchanger (10), and are disposed at a position lower than the mist spraying section (1). Therefore, the residual water in the water supply circuit for mist (11) flows back in the water supply circuit for mist (11) due to natural fall and is blocked by the electromagnetic valve (3), and an automatic drain valve (30 ) Through the drain pipe (12). Thus, hot water does not remain in the mist water supply circuit (11) after use on the downstream side of the solenoid valve (3). Therefore, it is not necessary to drain the residual water from the mist spraying section (1) at the next use, and the running cost can be saved.

上記参考例においては、ミスト用給水回路(11)内の水の逆流を防止する逆止弁(37)と、前記ミスト用給水回路(11)を開閉する電磁弁(3)とを、液々熱交換器(10)の上流側に設けて、ミスト用給水回路(11)の下流側は開放するように設定したから、液々熱交換器(10)に対応するミスト用給水回路(11)内が閉塞しない。よって、ミスト運転のウォームアップや、循環加熱回路(21)を加熱循環する凍結防止動作により、ミスト用給水回路(11)が加熱されても、電磁弁(3)に圧力がかかることはなく、電磁弁(3)が開き難くなる不都合はない。これにより、凍結防止動作時でも支障なくミスト装置を使用することができる。
又、前記循環加熱回路(21)及び分岐循環回路(22)内を循環する熱媒体としての温水には、一般に、プロピレングリコール等の不凍液が投入されており、これが、混入してミスト用給水回路(11)内が汚染されることは好ましくないが、万一、前記液々熱交換器(10)の破損等により、前記不凍液投入水がミスト用給水回路(11)内に混入してしまっても、逆止弁(37)によって、それ以上の逆流は阻止できるようになっているから、ミスト用給水回路(11)の上流である上水道に不凍液が混入して、上水が汚染される不都合は防止することができる。
In the above reference example , the check valve (37) for preventing the backflow of water in the mist water supply circuit (11) and the solenoid valve (3) for opening and closing the mist water supply circuit (11) The mist water supply circuit (11) corresponding to the liquid heat exchanger (10) is provided on the upstream side of the heat exchanger (10), and the downstream side of the mist water supply circuit (11) is set open. The inside does not block. Therefore, even if the water supply circuit for mist (11) is heated by the mist operation warm-up and the freeze prevention operation for heating and circulating the circulation heating circuit (21), no pressure is applied to the solenoid valve (3). There is no inconvenience that the solenoid valve (3) is difficult to open. Thus, the mist device can be used without any trouble even during the freeze prevention operation.
In addition, generally, an antifreeze liquid such as propylene glycol is added to the hot water as a heat medium circulating in the circulation heating circuit (21) and the branch circulation circuit (22), and this is mixed and supplied to the mist water supply circuit. (11) It is not preferable that the inside is contaminated, but in the unlikely event that the liquid heat exchanger (10) is damaged, the antifreeze liquid input water is mixed into the mist water supply circuit (11). However, since the check valve (37) can prevent further backflow, the antifreeze is mixed into the water supply upstream of the water supply circuit for mist (11) and the water is contaminated. Can be prevented.

[第実施形態について]
に示すフローチャートは第実施形態のミスト運転の制御に関するものであり、ミスト装置用の回路は、図に示した従来のものと同様な回路において、液々熱交換器(10)の上流側に逆止弁(37)を設けた構成のものが採用される
図2を参照して、この実施の形態では、S1のステップで、前記運転スイッチがON操作されたことが判別され、ミスト運転の開始が指令されると、S2のステップにて、暖房用熱源部(23)が作動し、流量制御弁(33)が設定開度に維持され、循環加熱回路(21)から分岐循環回路(22)を介して液々熱交換器(10)への熱媒体としての温水の供給が開始される。それと同時に、第2電磁弁(32)及び自動排水弁(30)が開弁して、ミスト用給水回路(11)への水道水の供給が開始される。そして、S3のステップで、ミストサーミスタ(35)でミスト用給水回路(11)内の温度(TW)が、ミスト噴霧用温度(YT)以上になったことが検知されると、S4のステップにて、第1電磁弁(31)が開弁すると共に、前記自動排水弁(30)が閉弁し、ミスト噴霧部(1)から浴室(4)に温水が噴霧される。この実施の形態のものでは、ミストサーミスタ(35)で検知される温度(TW)が前記ミスト用の設定温度(YT)以下の間は、自動排水弁(30)を介してミスト用給水回路(11)内の湯水を排水管(12)から排出するように設定されている。
S5のステップにて、ミスト運転スイッチがOFF操作されて、ミスト運転が停止されると、S6のステップに進んで、第2電磁弁(32)が閉じると共に、自動排水弁(30)が開弁して、第2電磁弁(32)より下流側の残留水の排水処理を行う。
この実施の形態では、ミスト運転開始時から第2電磁弁(32)を開弁してミスト用給水回路(11)内に湯水を通水しているため、ミスト用給水回路(11)内の圧が高まることがない。
[About the first embodiment]
Flowchart shown in FIG. 2 is related to control of the mist operation of the first embodiment, the circuit for mist device, in a similar circuit to that of the prior art shown in FIG. 4, a liquid-liquid heat exchanger (10) having a structure in which a check valve (37) on the upstream side is employed.
With reference to FIG. 2, in this embodiment, when it is determined in step S1 that the operation switch has been turned ON and the start of mist operation is commanded, in step S2, a heating heat source is generated. Section (23) operates, the flow control valve (33) is maintained at the set opening, and the heat medium from the circulation heating circuit (21) to the liquid-to-liquid heat exchanger (10) via the branch circulation circuit (22) Supply of hot water as is started. At the same time, the second solenoid valve (32) and the automatic drain valve (30) are opened, and the supply of tap water to the mist water supply circuit (11) is started. When the mist thermistor (35) detects that the temperature (TW) in the mist water supply circuit (11) is equal to or higher than the mist spraying temperature (YT) in step S3, the process proceeds to step S4. Thus, the first electromagnetic valve (31) is opened, the automatic drain valve (30) is closed, and hot water is sprayed from the mist spraying section (1) to the bathroom (4). In this embodiment, while the temperature (TW) detected by the mist thermistor (35) is equal to or lower than the mist set temperature (YT), the mist water supply circuit (30) is provided via the automatic drain valve (30). 11) It is set to discharge the hot water in the drain pipe (12).
When the mist operation switch is turned OFF in step S5 and the mist operation is stopped, the process proceeds to step S6, the second solenoid valve (32) is closed and the automatic drain valve (30) is opened. Then, the residual water on the downstream side of the second solenoid valve (32) is drained.
In this embodiment, since the second solenoid valve (32) is opened and hot water is passed through the mist water supply circuit (11) from the start of the mist operation, the water in the mist water supply circuit (11) is opened. Pressure does not increase.

[第実施形態について]
に示すものは、第実施形態におけるミスト装置の回路を示す説明図であり、図に示した従来の回路と同様に、液々熱交換器(10)の下流側に、開閉弁としての第1、第2電磁弁(31)(32)を配置させていると共に、前記第2電磁弁(32)の上流側で且つ逆止弁(37)の下流側に過圧逃がし手段としてブローバルブ(40)を設けて、前記第2電磁弁(32)と逆止弁(37)との間における前記ミスト用給水回路(11)内の圧力が設定作動圧力以上になると、前記ブローバルブ(40)が開いて圧を逃がす構成としている。暖房用熱源部(23)の燃焼により、液々熱交換器(10)を介してミスト用給水回路(11)が加熱されて、ミスト用給水回路(11)内の温水の体積膨張により第2電磁弁(32)と逆止弁(37)との間における前記ミスト用給水回路(11)の内圧が上昇するが、前記設定作動圧力以上になった時点で、前記ブローバルブ(40)が作動してミスト用給水回路(11)内の温水を排出するように設定されているから、ミスト用給水回路(11)内の圧力が過剰に高まることがない。よって、第2電磁弁(32)を液々熱交換器(10)の下流側に配設させても、前記第2電磁弁(32)に圧力がかかって開かないといった不都合は生じない。
尚、本発明の実施形態では、過圧逃がし手段として、ブローバルブを用いたが、アキュームレータを使用して圧力が上昇しない構成とすれば、ブローバルブのように排水が生じず、排水の処理を考慮する必要がない。
[About the second embodiment]
FIG. 3 is an explanatory view showing a circuit of the mist device in the second embodiment. Like the conventional circuit shown in FIG. 4 , an open / close valve is provided on the downstream side of the liquid heat exchanger (10). The first and second solenoid valves (31) and (32) are arranged as an overpressure relief means upstream of the second solenoid valve (32) and downstream of the check valve (37). When a blow valve (40) is provided and the pressure in the water supply circuit for mist (11) between the second solenoid valve (32) and the check valve (37) becomes equal to or higher than a set operating pressure, the blow valve (40) opens to release pressure. Due to the combustion of the heating heat source section (23), the water supply circuit for mist (11) is heated via the liquid heat exchanger (10), and the second expansion occurs due to the volume expansion of the hot water in the water supply circuit for mist (11). The internal pressure of the water supply circuit for mist (11) increases between the solenoid valve (32) and the check valve (37), but when the pressure exceeds the set operating pressure, the blow valve (40) is activated. Thus, since the hot water in the mist water supply circuit (11) is set to be discharged, the pressure in the mist water supply circuit (11) does not increase excessively. Therefore, even if the second electromagnetic valve (32) is disposed on the downstream side of the liquid-liquid heat exchanger (10), there is no inconvenience that the second electromagnetic valve (32) is not opened due to pressure.
In the embodiment of the present invention, the blow valve is used as the overpressure releasing means. However, if the pressure is not increased by using the accumulator, the drainage does not occur like the blow valve, and the wastewater is treated. There is no need to consider.
