Description

本発明は、浴室空調機に関するものである。 The present invention relates to a bathroom air conditioner.

従来、この種の浴室空調機は、浴室の天井面等に設置され、浴室の換気、乾燥、暖房、涼風、ミスト運転等を行うものが知られている。乾燥や暖房運転は、浴室空調機に吸い込まれた空気を加熱して行われる。 Conventionally, it is known that this type of bathroom air conditioner is installed on the ceiling surface of the bathroom or the like to perform ventilation, drying, heating, cool breeze, mist operation, etc. of the bathroom. Drying and heating operations are performed by heating the air sucked into the bathroom air conditioner.

空気を加熱する手段の一つとして、熱源機を利用した方法が挙げられる。熱源機とは、ガスによって湯を沸かす装置である。熱源機によって沸かされた湯、つまり温水は、風呂等への給湯のほか、温水の熱を利用して熱交換により空気等を加熱することができる。熱源機は、浴室空調機に備わる熱交換器へ温水を供給し、温水の供給を受けた熱交換器は、空気との間で熱交換を行い、空気を加熱することができる。 As one of the means for heating the air, there is a method using a heat source machine. A heat source machine is a device that boil water with gas. The hot water boiled by the heat source machine, that is, hot water, can heat the air or the like by heat exchange using the heat of the hot water in addition to supplying hot water to the bath or the like. The heat source machine supplies hot water to the heat exchanger provided in the bathroom air conditioner, and the heat exchanger supplied with the hot water can exchange heat with the air to heat the air.

また、熱源機によって作られた温水は、浴室空調機だけでなく床暖房等にも利用される。温水は、熱源機から温水流路を通り浴室空調機や床暖房等へ供給されていくが、それらの温水流路はつながっている。そのため、例えば浴室空調機で温水を使用する必要がない場合は、浴室空調機に対する温水の供給を停止する仕組みが必要である。その仕組みとして、浴室空調機は、温水流路を開閉するための流路開閉部を備えている。流路開閉部としては、たとえば熱動素子を利用して弁を開閉する熱動弁等が挙げられる。 In addition, the hot water produced by the heat source machine is used not only for bathroom air conditioners but also for floor heating and the like. Hot water is supplied from the heat source unit to the bathroom air conditioner, floor heating, etc. through the hot water flow path, and these hot water flow paths are connected. Therefore, for example, when it is not necessary to use hot water in the bathroom air conditioner, a mechanism for stopping the supply of hot water to the bathroom air conditioner is required. As a mechanism, the bathroom air conditioner is provided with a flow path opening / closing unit for opening / closing the hot water flow path. Examples of the flow path opening / closing portion include a thermal valve that opens and closes the valve using a thermal element.

流路開閉部が何らかの理由によって故障し、たとえば弁が正常に閉まらない場合、床暖房や給湯によって温水が温水流路を移動し始めると、浴室空調機に対しても温水が供給されることになる。その結果、たとえば涼風運転を指示しているにもかかわらず温風が出てくるといった、使用者にとって意図しない不具合が発生することが想定される。 If the flow path opening / closing part breaks down for some reason and the valve does not close normally, for example, when hot water starts to move in the hot water flow path due to floor heating or hot water supply, hot water will also be supplied to the bathroom air conditioner. Become. As a result, it is assumed that a problem unintended by the user occurs, for example, warm air is emitted even though the operation is instructed to be cool air.

このような課題に対して、例えば特許文献１に開示される浴室空調機は、温水が流れる流路近傍の温度を測定する流路近傍温度測定部を備えている。流路近傍温度測定部により測定された温度を用いて、流路開閉部の正常状態と異常状態を判断する。 To solve such a problem, for example, the bathroom air conditioner disclosed in Patent Document 1 includes a flow path vicinity temperature measuring unit for measuring the temperature in the vicinity of the flow path through which hot water flows. The normal state and abnormal state of the flow path opening / closing part are judged by using the temperature measured by the flow path vicinity temperature measuring unit.

このような浴室空調機は、流路開閉部の弁が正常に閉まらない異常状態を正しく判定できない場合がある。例えば、故障による温水の漏れ量が少ない場合、流路近傍温度測定部で測定される温度は所定温度に達しない可能性がある。このような場合、浴室空調機は、流路開閉部が異常状態であるにもかかわらず、異常状態と判定しない。また、温水の漏れ量が少ない場合に対応するため、異常状態と判定する所定温度を低く設定した場合、夏季など浴室空調機を含めた環境温度が高温となる場合、流路近傍温度測定部で測定される温度は、所定温度に達する可能性がある。このような場合、浴室空調機は、流路開閉部が正常状態であるにも関わらず、異常状態と判定する。 Such a bathroom air conditioner may not be able to correctly determine an abnormal state in which the valve of the flow path opening / closing portion does not close normally. For example, when the amount of hot water leaked due to a failure is small, the temperature measured by the flow path vicinity temperature measuring unit may not reach a predetermined temperature. In such a case, the bathroom air conditioner does not determine the abnormal state even though the flow path opening / closing part is in the abnormal state. In addition, in order to deal with the case where the amount of hot water leaks is small, if the predetermined temperature for determining an abnormal state is set low, or if the environmental temperature including the bathroom air conditioner becomes high, such as in summer, the temperature measurement unit near the flow path will be used. The measured temperature can reach a predetermined temperature. In such a case, the bathroom air conditioner determines that the flow path opening / closing portion is in an abnormal state even though it is in a normal state.

そこで本発明は、上記従来の課題を解決するものであり、流路開閉部を通過する温水の漏れ量や環境温度によらず、流路開閉部の正常状態と異常状態の判定を行うことが可能な浴室空調機を提供することを目的とする。 Therefore, the present invention solves the above-mentioned conventional problems, and can determine the normal state and the abnormal state of the flow path opening / closing part regardless of the amount of hot water leaking through the flow path opening / closing part and the environmental temperature. The purpose is to provide a possible bathroom air conditioner.

そして、この目的を達成するために、本発明に係る浴室空調機は、通過する空気と温水との間で熱交換する熱交換器と、前記熱交換器に前記温水を供給する第一温水流路と、前記第一温水流路を開閉する第一温水流路開閉部と、前記第一温水流路の近傍温度を測定する温水流路温度測定部と、前記熱交換器を通過する前記空気の温度を測定する空気温度測定部と、前記温水流路温度測定部で測定された温水流路温度と前記空気温度測定部で測定された空気温度との第一温度差及び前記第一温水流路開閉部の第一温水流路開閉情報に基づき、前記第一温水流路開閉部の正常状態または異常状態を判定する第一状態判定部と、を備えたものであり、これにより所期の目的を達成するものである。 Then, in order to achieve this object, the bathroom air conditioner according to the present invention has a heat exchanger that exchanges heat between the passing air and hot water, and a first hot water stream that supplies the hot water to the heat exchanger. The path, the first hot water flow path opening / closing section for opening / closing the first hot water flow path, the hot water flow path temperature measuring section for measuring the temperature in the vicinity of the first hot water flow path, and the air passing through the heat exchanger. The first temperature difference between the air temperature measuring unit for measuring the temperature of the water, the hot water flow path temperature measured by the hot water flow path temperature measuring unit, and the air temperature measured by the air temperature measuring unit, and the first hot water flow. Based on the first hot water flow path opening / closing information of the path opening / closing part, the first state determination unit for determining the normal state or the abnormal state of the first hot water flow path opening / closing part is provided. It achieves the purpose.

本発明によれば、流路開閉部を通過する温水の漏れ量や環境温度によらず、流路開閉部の正常状態と異常状態の判定を行うという効果を得ることができる。 According to the present invention, it is possible to obtain the effect of determining the normal state and the abnormal state of the flow path opening / closing part regardless of the amount of hot water leaking through the flow path opening / closing part and the environmental temperature.

The temperature of the air passing through the heat exchanger 6 refers to the temperature of the air within the range affected by at least one of heat conduction, heat transfer, and heat radiation by the hot water passing through the heat exchanger 6. As a result, the air temperature measuring unit 19 can be expected to have the effect of accurately measuring the temperature rise of the air due to the heat of the hot water even when the amount of hot water passing through the heat exchanger 6 is small.

さらに、浴室暖房乾燥機１は、第一温水流路２０と、第一温水流路開閉部２２と、温水流路温度測定部２３と、熱交換器６と、第一温水流路２０と、第二温水流路２１と、水熱交換器９と、第二温水流路開閉部２４とを備えている。 Further, the bathroom heater / dryer 1 includes a first hot water flow path 20, a first hot water flow path opening / closing unit 22, a hot water flow path temperature measuring unit 23, a heat exchanger 6, a first hot water flow path 20, and the like.

The heat receiving water flow path temperature measuring unit 26 is arranged on the outer peripheral surface of the pipe forming the heat receiving water flow path 25. The temperature in the vicinity of the heat receiving water flow path 25 refers to the temperature of the pipes constituting the heat receiving water flow path 25 within the range affected by at least one of heat conduction, heat transfer, and heat radiation by the received tap water. As a result, the heat receiving water flow path temperature measuring unit 26 accurately raises the temperature of the pipes constituting the heat receiving water flow path 25 due to the received tap water even when the amount of hot water passing through the second hot water flow path 21 is small.

第二状態判定部３６ｄは、入力部３６ａが受け取った情報と、記憶部３６ｅが記憶している情報と、計時部３６ｆとから第二温水流路開閉部２４の正常状態または異常状態を判定する。 The second state determination unit 36d determines the normal state or abnormal state of the second hot water flow path opening / closing unit 24 from the information received by the input unit 36a, the information stored in the storage unit 36e, and the timing unit 36f. ..

記憶部３６ｅは、送風機１８の風量情報、第一温水流路開閉部２２の開閉情報、第二温水流路開閉部２４の開閉情報、第一温水流路開閉部２２や第二温水流路開閉部２４が異常状態と判定するための所定温度情報等を記憶している。 The storage unit 36e includes air volume information of the blower 18, opening / closing information of the first hot water flow path opening / closing part 22, opening / closing information of the second hot water flow path opening / closing part 24, opening / closing of the first hot water flow path opening / closing part 22 and the second hot water flow path. The unit 24 stores predetermined temperature information and the like for determining an abnormal state.

計時部３６ｆは、乾燥・暖房運転の残り時間、第一状態判定部３６ｃが第一温水流路開閉部２２の異常状態を判定するための時間、第二状態判定部３６ｄが第二温水流路開閉部２４の異常状態を判定するための時間などの計測を行う。 The time measuring unit 36f is the remaining time of the drying / heating operation, the time for the first state determination unit 36c to determine the abnormal state of the first hot water flow path opening / closing unit 22, and the second state determination unit 36d for the second hot water flow path. The time for determining the abnormal state of the opening / closing unit 24 is measured.

出力部３６ｈは、加湿ユニット１０と、送風機１８と、第一温水流路開閉部２２と、第二温水流路開閉部２４と、リモコン３３と、に電気的に通信可能に接続している。出力部３６ｈは、処理部３６ｂにより処理された情報を加湿ユニット１０、送風機１８、第一温水流路開閉部２２、第二温水流路開閉部２４、リモコン３３のいずれか、または複数同時に出力する。 The output unit 36h is electrically communicably connected to the humidification unit 10, the blower 18, the first hot water flow path opening / closing unit 22, the second hot water flow path opening / closing unit 24, and the remote controller 33. The output unit 36h simultaneously outputs the information processed by the processing unit 36b to any one or a plurality of the humidifying unit 10, the blower 18, the first hot water flow path opening / closing unit 22, the second hot water flow path opening / closing unit 24, and the remote controller 33. ..

以上が、制御部３６の構成である。次に、温水の熱を利用した浴室暖房乾燥機１の運転について説明する。 The above is the configuration of the control unit 36. Next, the operation of the bathroom heater / dryer 1 using the heat of hot water will be described.

浴室暖房乾燥機１は、熱源機で沸かされた湯（例えば８０℃）の持つ熱を利用して、暖房運転やミスト運転を行うことができる。 The bathroom heater / dryer 1 can perform a heating operation or a mist operation by utilizing the heat of hot water (for example, 80 ° C.) boiled by a heat source machine.

暖房運転の場合、まずユーザーがリモコン３３の物理ボタン３４から暖房運転を選択する。制御部３６は、暖房運転の指示を入力部３６ａで受け取ると、処理部３６ｂを通して暖房運転に必要な情報を記憶部３６ｅから読み出す。制御部３６は、読み出した暖房運転に必要な情報を実行するように出力部３６ｈを通して浴室暖房乾燥機１の構成要素に動作の指示を出す。暖房運転に必要な動作の指示とは、例えば送風機１８の運転開始、第一温水流路開閉部の弁を開くといった指示が挙げられる。熱交換器６は、第一温水流路２０へ温水を通すことで加熱される。温水により加熱された熱交換器６は、送風機１８によって吸込口１３から吸い込まれた空気との間で熱交換を行う。熱交換器６を通過して受熱した空気、つまり温風は、循環風路１７を通り、吹出口１４から吹出される。これにより、例えば浴室が乾きにくい冬季では、カビの発生を抑制するために浴室の乾燥を促進することができる。また、同じく冬季において、入浴前に浴室を温めておくことで、入浴者がヒートショックを起こす可能性を軽減する効果が期待できる。 In the case of the heating operation, the user first selects the heating operation from the physical button 34 of the remote controller 33. When the control unit 36 receives the instruction of the heating operation from the input unit 36a, the control unit 36 reads out the information necessary for the heating operation from the storage unit 36e through the processing unit 36b. The control unit 36 gives an operation instruction to the components of the bathroom heater / dryer 1 through the output unit 36h so as to execute the read information necessary for the heating operation. Examples of the operation instruction required for the heating operation include instructions such as starting the operation of the blower 18 and opening the valve of the first hot water flow path opening / closing portion. The heat exchanger 6 is heated by passing hot water through the first hot water flow path 20. The heat exchanger 6 heated by hot water exchanges heat with the air sucked from the suction port 13 by the blower 18. The air that has passed through the heat exchanger 6 and received heat, that is, warm air, passes through the circulation air passage 17 and is blown out from the air outlet 14. As a result, for example, in winter when the bathroom is difficult to dry, it is possible to promote the drying of the bathroom in order to suppress the generation of mold. Also, in winter, by warming the bathroom before bathing, the effect of reducing the possibility of the bather causing heat shock can be expected.

ミスト運転の場合、まずユーザーがリモコン３３の物理ボタン３４からミスト運転を選択する。このとき、上述した暖房運転の場合と同様に、制御部３６は、ミスト運転に必要な動作の指示を浴室暖房乾燥機１の構成要素に対して出す。ミスト運転に必要な動作の指示とは、例えば加湿ユニット１０の運転開始、送風機１８の運転開始、第二温水流路開閉部２４の弁を開くといった指示が挙げられる。水熱交換器９は、第二温水流路２１へ温水を通すことで加熱される。温水により加熱された水熱交換器９は、加湿流路８を通る水道水との間で熱交換を行う。水熱交換器９を通過して受熱した水は、受熱水流路２５を通り、加湿ユニット１０へ供給される。加湿ユニット１０へ供給された水は、マイクロメートル以下の粒径を持つマイクロミストとなり、循環風路１７を通る空気を加湿する。そして、マイクロミストにより加湿された空気は、吹出口１４より吹出される。これにより、使用者は、例えば入浴前であれば加湿しながら浴室を温めることができる。また、入浴中であれば、ミストサウナと呼ばれる湿式のサウナを作ることができる。湿式サウナとは、乾式サウナと比べて低温度・高湿度であることを特徴とした熱気浴の一種である。 In the case of mist operation, the user first selects mist operation from the physical button 34 of the remote controller 33. At this time, as in the case of the heating operation described above, the control unit 36 issues an operation instruction necessary for the mist operation to the components of the bathroom heater / dryer 1. Examples of the operation instructions required for the mist operation include instructions such as starting the operation of the humidifying unit 10, starting the operation of the blower 18, and opening the valve of the second hot water flow path opening / closing unit 24. The water heat exchanger 9 is heated by passing hot water through the second hot water flow path 21. The water heat exchanger 9 heated by hot water exchanges heat with tap water passing through the humidification flow path 8. The water that has passed through the water heat exchanger 9 and received heat is supplied to the humidifying unit 10 through the heat receiving water flow path 25. The water supplied to the humidification unit 10 becomes a micromist having a particle size of micrometer or less, and humidifies the air passing through the circulation air passage 17. Then, the air humidified by the micro mist is blown out from the air outlet 14. As a result, the user can warm the bathroom while humidifying, for example, before taking a bath. Also, if you are taking a bath, you can make a wet sauna called a mist sauna. A wet sauna is a type of hot air bath characterized by a lower temperature and higher humidity than a dry sauna.

このように、浴室暖房乾燥機１は、熱源機の作る温水を利用して、浴室の温度と湿度を制御することができる。 In this way, the bathroom heater / dryer 1 can control the temperature and humidity of the bathroom by using the hot water produced by the heat source machine.

ところで、熱源機によって作られた温水は、浴室暖房乾燥機１だけではなく、給湯や床暖房としても利用される。熱源機を出た温水は、いくつかの分岐した流路を通りながら給湯用の蛇口や床暖房機器へ供給される。本発明で開示した温水流路５は、前述の分岐した流路のうちのひとつである。熱源機によって作られた温水は、いくつかの分岐した流路を通ったあと、再び熱源機へと戻るものが一般的である。このため、温水を利用する機器は、温水の供給が不要な場合に温水が流路を通ることを防止するため、本発明で開示した第一温水流路開閉部２２や第二温水流路開閉部２４のように、温水が流れる流路を開閉する弁を備えている。 By the way, the hot water produced by the heat source machine is used not only for the bathroom heater / dryer 1 but also for hot water supply and floor heating. The hot water from the heat source unit is supplied to the hot water supply faucet and floor heating equipment while passing through several branched channels. The hot water flow path 5 disclosed in the present invention is one of the above-mentioned branched flow paths. The hot water produced by the heat source machine generally returns to the heat source machine after passing through several branched channels. Therefore, in the device using hot water, in order to prevent the hot water from passing through the flow path when the hot water supply is not required, the first hot water flow path opening / closing section 22 and the second hot water flow path opening / closing unit disclosed in the present invention are opened and closed. Like the part 24, it is provided with a valve that opens and closes a flow path through which hot water flows.

弁を閉じることにより、温水が不要な機器にまで温水が流れることによって発生する熱エネルギーの損失を抑制できる。また、浴室暖房乾燥機１は、夏季など浴室が高温になる環境において清掃など行う場合、温水による熱交換を行わず、送風機１８による循環送風の気流によって使用者に涼感を与える涼風運転を備えている。第一温水流路開閉部２２を備えていない場合、涼風運転の実行中に、例えば洗面所や台所への給湯が開始されると、熱交換器６へも温水が供給され、温風が出てくることになる。また、第二温水流路開閉部２４は、受熱水の温度の制御を目的として第二温水流路２１の開度を調節することもできる弁である。第二温水流路開閉部２４があることで、温水ミストの温度を調節することができる。第二温水流路開閉部２４を備えていない場合、温水ミストの温度調節が出来ず、使用者にとって不都合な高温のミストが発生する可能性がある。 By closing the valve, it is possible to suppress the loss of heat energy generated by the flow of hot water to equipment that does not require hot water. Further, the bathroom heater / dryer 1 is provided with a cool breeze operation that gives a cool feeling to the user by the air flow of the circulating air blown by the blower 18 without exchanging heat with hot water when cleaning or the like in an environment where the bathroom becomes hot such as in summer. There is. When the first hot water flow path opening / closing unit 22 is not provided, hot water is also supplied to the heat exchanger 6 and hot air is emitted when, for example, hot water supply to the washroom or kitchen is started during the execution of the cool air operation. Will come. Further, the second hot water flow path opening / closing unit 24 is a valve capable of adjusting the opening degree of the second hot water flow path 21 for the purpose of controlling the temperature of the received water. The temperature of the hot water mist can be adjusted by the presence of the second hot water flow path opening / closing portion 24. If the second hot water flow path opening / closing portion 24 is not provided, the temperature of the hot water mist cannot be controlled, and a high temperature mist that is inconvenient for the user may be generated.

こうしたことから、第一温水流路開閉部２２と第二温水流路開閉部２４は、浴室暖房乾燥機１へ適切なタイミングで温水を供給するために必要不可欠な部材である。このため、第一温水流路開閉部２２と第二温水流路開閉部２４の異常状態を正確に判定することが重要である。そこで、制御部３６は、第一温水流路開閉部２２の弁の閉状態に対する異常状態を判定する第一状態判定部３６ｃと、第二温水流路開閉部２４の弁の閉状態に対する異常状態を判定する第二状態判定部３６ｄとを備えている。 For these reasons, the first hot water flow path opening / closing section 22 and the second hot water flow path opening / closing section 24 are indispensable members for supplying hot water to the bathroom heater / dryer 1 at an appropriate timing. Therefore, it is important to accurately determine the abnormal state of the first hot water flow path opening / closing section 22 and the second hot water flow path opening / closing section 24. Therefore, the control unit 36 has a first state determination unit 36c that determines an abnormal state of the valve of the first hot water flow path opening / closing unit 22 with respect to the closed state, and an abnormal state of the second hot water flow path opening / closing unit 24 with respect to the closed state of the valve. It is provided with a second state determination unit 36d for determining.

それでは次に、制御部３６による第一温水流路開閉部２２の異常状態を判定及び報知するフローについて、図５のフローチャートを用いて説明する。 Next, a flow for determining and notifying the abnormal state of the first hot water flow path opening / closing unit 22 by the control unit 36 will be described with reference to the flowchart of FIG.

なお第一温水流路開閉部２２の異常状態とは、制御部３６が第一温水流路開閉部２２に対して弁を閉状態とするように指示しているにもかかわらず、何らかの理由により弁が閉じられず、第一温水流路２０へ温水が流れてしまう状態を指す。 The abnormal state of the first hot water flow path opening / closing unit 22 is due to some reason even though the control unit 36 has instructed the first hot water flow path opening / closing unit 22 to close the valve. It refers to a state in which the valve is not closed and hot water flows into the first hot water flow path 20.

リモコン３３から浴室暖房乾燥機１の運転停止が選択されると、入力部３６ａは運転停止の情報を受け取る。処理部３６ｂは、入力部３６ａが受け取った運転停止の情報に基づき、記憶部３６ｅから送風機１８や第一温水流路開閉部２２の動作処理についての情報を読み出す。そして、記憶部３６ｅから読み出された情報を実行するように出力部３６ｈから送風機１８や第一温水流路開閉部２２などへ指示が出される（ステップＳ１）。例えば、運転停止の指示を出す前に、運転種別のひとつである暖房運転を選択していた場合は、送風機１８を停止し、第一温水流路開閉部２２の弁を閉にするなどの動作を行う。 When the operation stop of the bathroom heater / dryer 1 is selected from the remote controller 33, the input unit 36a receives the operation stop information. The processing unit 36b reads out information about the operation processing of the blower 18 and the first hot water flow path opening / closing unit 22 from the storage unit 36e based on the operation stop information received by the input unit 36a. Then, an instruction is issued from the output unit 36h to the blower 18 and the first hot water flow path opening / closing unit 22 so as to execute the information read from the storage unit 36e (step S1). For example, if the heating operation, which is one of the operation types, is selected before issuing the operation stop instruction, the blower 18 is stopped and the valve of the first hot water flow path opening / closing unit 22 is closed. I do.

次に、計時部３６ｆは、運転停止が選択されてから経過した時間の計測を行う。制御部３６は、計時部３６ｆが計測した時間が第一所定時間ＴＩＭＥ１（例えば６０分）に達したかの判定を行う（ステップＳ２）。第一所定時間ＴＩＭＥ１に達していなければ、制御部３６はステップＳ２を繰り返す。 Next, the timekeeping unit 36f measures the time elapsed since the stop operation was selected. The control unit 36 determines whether the time measured by the time measuring unit 36f has reached the first predetermined time TIME1 (for example, 60 minutes) (step S2). If the first predetermined time TIME1 has not been reached, the control unit 36 repeats step S2.

第一所定時間ＴＩＭＥ１は、例えば運転停止が選択されてから空気温度ＴＥＭＰ１や温水流路温度ＴＥＭＰ２の値が常温まで下がり、安定するまでの時間を選定することが好ましい。 For the first predetermined time TIME1, for example, it is preferable to select the time from when the operation stop is selected until the values of the air temperature TEMP1 and the hot water flow path temperature TEMP2 decrease to room temperature and stabilize.

制御部３６は、第一所定時間ＴＩＭＥ１を超えたと判断した場合、第一状態判定部３６ｃを用いて第一温水流路開閉部２２の開閉情報と温水流路温度ＴＥＭＰ２との情報に基づき、第一温水流路開閉部２２の正常状態または異常状態の判定を行う。 When the control unit 36 determines that the first predetermined time TIME1 has been exceeded, the control unit 36 uses the first state determination unit 36c based on the information on the opening / closing information of the first hot water flow path opening / closing unit 22 and the hot water flow path temperature TEMP2. It is determined whether the hot water flow path opening / closing unit 22 is in a normal state or an abnormal state.

まず、制御部３６は、温水流路温度ＴＥＭＰ２が第一所定温度Ａを越えているかの判断を行う（ステップＳ３）。温水流路温度ＴＥＭＰ２が第一所定温度Ａを越えていると判断した場合、制御部３６は、温水流路温度ＴＥＭＰ２が第一所定温度Ａを越えている時間が第二所定時間ＴＩＭＥ２を超えるかの判定を行う（ステップＳ４）。温水流路温度ＴＥＭＰ２が第一所定温度Ａを越えている時間が第二所定時間ＴＩＭＥ２を超えた場合、第一状態判定部３６ｃは第一温水流路開閉部２２が異常状態であると判断する。そして、制御部３６は、報知部３５を通して異常状態の報知を開始するように制御する（ステップＳ５）。 First, the control unit 36 determines whether the hot water flow path temperature TEMP2 exceeds the first predetermined temperature A (step S3). When it is determined that the hot water flow path temperature TEMP2 exceeds the first predetermined temperature A, the control unit 36 determines whether the time when the hot water flow path temperature TEMP2 exceeds the first predetermined temperature A exceeds the second predetermined time TIME2. Is determined (step S4). When the time when the hot water flow path temperature TEMP2 exceeds the first predetermined temperature A exceeds the second predetermined time TIME2, the first state determination unit 36c determines that the first hot water flow path opening / closing unit 22 is in an abnormal state. .. Then, the control unit 36 controls to start the notification of the abnormal state through the notification unit 35 (step S5).

報知部３５による異常状態の報知が開始されたあとも、制御部３６は温水流路温度ＴＥＭＰ２が第一所定温度Ａを越えているかの判断を行う（ステップＳ６）。 Even after the notification of the abnormal state is started by the notification unit 35, the control unit 36 determines whether the hot water flow path temperature TEMP2 exceeds the first predetermined temperature A (step S6).

温水流路温度ＴＥＭＰ２が第一所定温度Ａ以下となった場合、第一状態判定部３６ｃは、第一温水流路開閉部２２が正常状態であると判定する。そして、制御部３６は、報知部３５に対して異常状態の報知を停止するように制御する（ステップＳ７）。異常状態の報知を停止したあと、制御部３６による処理ステップは、ステップＳ３へ戻る。 When the hot water flow path temperature TEMP2 becomes the first predetermined temperature A or less, the first state determination unit 36c determines that the first hot water flow path opening / closing unit 22 is in a normal state. Then, the control unit 36 controls the notification unit 35 to stop the notification of the abnormal state (step S7). After stopping the notification of the abnormal state, the processing step by the control unit 36 returns to step S3.

第一状態判定部３６ｃは、温水流路温度ＴＥＭＰ２が第一所定温度Ａを超えないと判断した場合、空気温度ＴＥＭＰ１と温水流路温度ＴＥＭＰ２との第一温度差ΔＴ１が第二所定温度Ｂ（例えば１０℃）を超えるか判定を行う（ステップＳ７）。 When the first state determination unit 36c determines that the hot water flow path temperature TEMP2 does not exceed the first predetermined temperature A, the first temperature difference ΔT1 between the air temperature TEMP1 and the hot water flow path temperature TEMP2 is the second predetermined temperature B ( For example, it is determined whether or not the temperature exceeds 10 ° C. (step S7).

第一温度差ΔＴ１が第二所定温度Ｂを超える場合、第一状態判定部３６ｃは、第一温度差ΔＴ１が第二所定温度Ｂを超える時間が第三所定時間ＴＩＭＥ３を超えるか判定を行う（ステップＳ８）。第一温度差ΔＴ１が第二所定温度Ｂを超える時間が第三所定時間ＴＩＭＥ３を超える場合、第一状態判定部３６ｃは、第一温水流路開閉部２２が異常状態であると判定する。そして制御部３６は、報知部３５に対して異常状態の報知を開始するように制御する（ステップＳ９）。 When the first temperature difference ΔT1 exceeds the second predetermined temperature B, the first state determination unit 36c determines whether the time when the first temperature difference ΔT1 exceeds the second predetermined temperature B exceeds the third predetermined time TIME3 ( Step S8). When the time when the first temperature difference ΔT1 exceeds the second predetermined temperature B exceeds the third predetermined time TIME3, the first state determination unit 36c determines that the first hot water flow path opening / closing unit 22 is in an abnormal state. Then, the control unit 36 controls the notification unit 35 to start notifying the abnormal state (step S9).

報知部３５による異常状態の報知が開始されたあとも、第一状態判定部３６ｃは第一温度差ΔＴ１が第二所定温度Ｂを超えるかの判断を行う（ステップＳ１０）。第一温度差ΔＴ１が第二所定温度Ｂを越えない場合、制御部３６は、第一温水流路開閉部２２が正常状態であると判定し、報知部３５に対して異常状態の報知を停止するように指示する（ステップＳ１１）。 Even after the notification of the abnormal state by the notification unit 35 is started, the first state determination unit 36c determines whether the first temperature difference ΔT1 exceeds the second predetermined temperature B (step S10). When the first temperature difference ΔT1 does not exceed the second predetermined temperature B, the control unit 36 determines that the first hot water flow path opening / closing unit 22 is in a normal state, and stops notifying the notification unit 35 of the abnormal state. Instruct to do so (step S11).

制御部３６は、暖房運転や乾燥運転など、浴室暖房乾燥機１の運転開始に関する情報を入力部３６ａが受け取るまで、ステップＳ３からステップＳ１１の処理を繰り返す（ステップＳ１２）。 The control unit 36 repeats the processes of steps S3 to S11 until the input unit 36a receives information regarding the start of operation of the bathroom heater / dryer 1, such as the heating operation and the drying operation (step S12).

以上が、制御部３６による第一温水流路開閉部２２の異常状態を判定及び報知するフローの説明である。 The above is the description of the flow for determining and notifying the abnormal state of the first hot water flow path opening / closing unit 22 by the control unit 36.

次に、制御部３６による第二温水流路開閉部２４の異常状態を判定及び報知するフローについて、図６を用いて説明する。 Next, a flow for determining and notifying the abnormal state of the second hot water flow path opening / closing unit 24 by the control unit 36 will be described with reference to FIG.

第二温水流路開閉部２４の異常状態とは、制御部３６が第二温水流路開閉部２４に対して弁を閉状態とするように指示しているにもかかわらず、何らかの理由により弁が閉じられず、第二温水流路２１へ温水が流れてしまう状態を指す。 The abnormal state of the second hot water flow path opening / closing unit 24 is a valve for some reason even though the control unit 36 instructs the second hot water flow path opening / closing unit 24 to close the valve. Refers to a state in which hot water flows into the second hot water flow path 21 without being closed.

制御部３６は、リモコン３３から運転停止の指示を受け取ると、運転停止に関する情報を記憶部３６ｅから読み出して、出力部３６ｈから運転停止の指示を送風機１８などへ出す（ステップＳ１）。例えば、運転停止の指示を出す前に、運転種別のひとつである暖房運転を選択していた場合は、送風機１８を停止し、第二温水流路開閉部２４の弁を閉にするなどの動作を行う。 When the control unit 36 receives the operation stop instruction from the remote controller 33, the control unit 36 reads the operation stop information from the storage unit 36e and issues the operation stop instruction from the output unit 36h to the blower 18 or the like (step S1). For example, if the heating operation, which is one of the operation types, is selected before issuing the operation stop instruction, the blower 18 is stopped and the valve of the second hot water flow path opening / closing unit 24 is closed. I do.

第一所定時間ＴＩＭＥ１は、例えば運転停止が選択されてから空気温度ＴＥＭＰ１や受熱水流路温度ＴＥＭＰ３の値が常温まで下がり、安定するまでの時間を選定することが好ましい。 For the first predetermined time TIME1, for example, it is preferable to select the time from when the operation stop is selected until the values of the air temperature TEMP1 and the heat receiving water flow path temperature TEMP3 decrease to room temperature and stabilize.

制御部３６は、第一所定時間ＴＩＭＥ１を超えた場合、第二状態判定部３６ｄを用いて第二温水流路開閉部２４の開閉情報と受熱水流路温度ＴＥＭＰ３との情報に基づき、第二温水流路開閉部２４の正常状態または異常状態の判定を行う。 When the control unit 36 exceeds TIME1 for the first predetermined time, the control unit 36 uses the second state determination unit 36d to use the second hot water flow path opening / closing unit 24 based on the information of the opening / closing information of the second hot water flow path opening / closing unit 24 and the heat receiving water flow path temperature TEMP3. The normal state or the abnormal state of the flow path opening / closing unit 24 is determined.

まず、制御部３６は、受熱水流路温度ＴＥＭＰ３が第三所定温度Ｃを越えているかの判断を行う（ステップＳ１３）。 First, the control unit 36 determines whether the heat receiving water flow path temperature TEMP3 exceeds the third predetermined temperature C (step S13).

受熱水流路温度ＴＥＭＰ３が第三所定温度Ｃを超えた場合、第二状態判定部３６ｄは、受熱水流路温度ＴＥＭＰ３が第三所定温度Ｃを超えた時間が第四所定時間ＴＩＭＥ４を超えるかの判断を行う（ステップＳ１４）。 When the hot water flow path temperature TEMP3 exceeds the third predetermined temperature C, the second state determination unit 36d determines whether the time when the hot water flow path temperature TEMP3 exceeds the third predetermined temperature C exceeds the fourth predetermined time TIME4. (Step S14).

受熱水流路温度ＴＥＭＰ３が第三所定温度Ｃを超えた時間が第五所定時間ＴＩＭＥ５を超えた場合、第二状態判定部３６ｄは、第二温水流路開閉部２４が異常状態であると判断する。そして、制御部３６は、報知部３５に対して異常状態の報知を開始するように指示する（ステップＳ１５）。 When the time when the hot water flow path temperature TEMP3 exceeds the third predetermined temperature C exceeds the fifth predetermined time TIME5, the second state determination unit 36d determines that the second hot water flow path opening / closing unit 24 is in an abnormal state. .. Then, the control unit 36 instructs the notification unit 35 to start the notification of the abnormal state (step S15).

報知部３５による異常状態の報知が開始されたあとも、第二状態判定部３６ｄは、受熱水流路温度ＴＥＭＰ３が第三所定温度Ｃを越えているかの判断を行う（ステップＳ１６）。受熱水流路温度ＴＥＭＰ３が第三所定温度Ｃ以下となった場合、制御部３６は報知部３５に対して異常状態の報知を停止するように制御する（ステップＳ１７）。異常状態の報知を停止したあと、制御部３６による処理ステップは、ステップＳ１３へ戻る。 Even after the notification of the abnormal state by the notification unit 35 is started, the second state determination unit 36d determines whether the heat receiving water flow path temperature TEMP3 exceeds the third predetermined temperature C (step S16). When the hot water flow path temperature TEMP3 becomes equal to or lower than the third predetermined temperature C, the control unit 36 controls the notification unit 35 to stop the notification of the abnormal state (step S17). After stopping the notification of the abnormal state, the processing step by the control unit 36 returns to step S13.

受熱水流路温度ＴＥＭＰ３が第三所定温度Ｃを超えない場合、第二状態判定部３６ｄは、空気温度ＴＥＭＰ１と受熱水流路温度ＴＥＭＰ３との第二温度差ΔＴ２が第四所定温度Ｄ（例えば１０℃）を超えるか判定を行う（ステップＳ１８）。 When the hot water flow path temperature TEMP3 does not exceed the third predetermined temperature C, the second state determination unit 36d determines that the second temperature difference ΔT2 between the air temperature TEMP1 and the hot water flow path temperature TEMP3 is the fourth predetermined temperature D (for example, 10 ° C.). ) Is exceeded (step S18).

第二温度差ΔＴ２が第四所定温度Ｄを超える場合、第二状態判定部３６ｄは、第二温度差ΔＴ２が第四所定温度Ｄを超える時間が第五所定時間ＴＩＭＥ５を超えるか判定を行う（ステップＳ１９）。第二温度差ΔＴ２が第四所定温度Ｄを超える時間が第五所定時間ＴＩＭＥ５を超える場合、第二状態判定部３６ｄは、第二温水流路開閉部２４が異常状態であると判定する。そして、制御部３６は、報知部３５に対して異常状態の報知を開始するように制御する（ステップＳ２０）。 When the second temperature difference ΔT2 exceeds the fourth predetermined temperature D, the second state determination unit 36d determines whether the time when the second temperature difference ΔT2 exceeds the fourth predetermined temperature D exceeds the fifth predetermined time TIME5 ( Step S19). When the time when the second temperature difference ΔT2 exceeds the fourth predetermined temperature D exceeds the fifth predetermined time TIME5, the second state determination unit 36d determines that the second hot water flow path opening / closing unit 24 is in an abnormal state. Then, the control unit 36 controls the notification unit 35 to start notifying the abnormal state (step S20).

報知部３５による異常状態の報知が開始されたあとも、第二状態判定部３６ｄは、第二温度差ΔＴ２が第四所定温度Ｄを超えるか判定を行う（ステップＳ２１）。第二温度差ΔＴ２が第四所定温度Ｄを越えない場合、制御部３６は、第二温水流路開閉部２４が正常状態であると判定し、報知部３５に対して異常状態の報知を停止するように指示する（ステップＳ２２）。 Even after the notification of the abnormal state by the notification unit 35 is started, the second state determination unit 36d determines whether the second temperature difference ΔT2 exceeds the fourth predetermined temperature D (step S21). When the second temperature difference ΔT2 does not exceed the fourth predetermined temperature D, the control unit 36 determines that the second hot water flow path opening / closing unit 24 is in a normal state, and stops notifying the notification unit 35 of the abnormal state. Instruct to do so (step S22).

制御部３６は、暖房運転や乾燥運転など、浴室暖房乾燥機１の運転開始に関する情報を受け取るまでステップＳ１３からステップＳ２２の処理を繰り返す（ステップＳ２３）。 The control unit 36 repeats the processes of steps S13 to S22 until it receives information regarding the start of operation of the bathroom heater / dryer 1, such as the heating operation and the drying operation (step S23).

つまり、第一状態判定部３６ｃによる異常状態の判定方法は、温水流路温度測定部２３により測定された温水流路温度ＴＥＭＰ２によるものと、温水流路温度測定部２３により測定された温水流路温度ＴＥＭＰ２と空気温度測定部１９により測定された空気温度ＴＥＭＰ１との第一温度差ΔＴ１によるものとの２種類である。これは、以下の理由による。 That is, the method of determining the abnormal state by the first state determination unit 36c is based on the hot water flow path temperature TEMP2 measured by the hot water flow path temperature measuring unit 23 and the hot water flow path measured by the hot water flow path temperature measuring unit 23. There are two types, one is based on the first temperature difference ΔT1 between the temperature TEMP2 and the air temperature TEMP1 measured by the air temperature measuring unit 19. This is due to the following reasons.

まず、温水流路温度ＴＥＭＰ２は、第一温水流路開閉部２２の開度によって変化する。例えば、第一温水流路開閉部２２の開度を０から１００の範囲としたとき、開度が１００の状態で測定される温水流路温度ＴＥＭＰ２が５０℃だとすると、開度が５０の状態で測定される温水流路温度ＴＥＭＰ２は、５０℃よりも低くなり、例えば４０℃となる。ここで、第一所定温度Ａ＝５０℃とすると、第一温水流路開閉部２２の開度が１００の状態で故障した場合は異常状態を判定できるが、開度が５０の状態で故障した場合は異常状態を判定できなくなる。また、第一所定温度Ａ＝４０℃と設定すると、夏季など天井裏の空間が４０℃以上の高温となる可能性がある場合には、第一温水流路開閉部２２の弁の閉状態が正常であっても誤検知となる場合がある。すなわち、温水流路温度ＴＥＭＰ２による異常状態の判定だけでは、正しい判定ができないのである。そこで、空気温度ＴＥＭＰ１と温水流路温度ＴＥＭＰ２の相対比較を行う。 First, the hot water flow path temperature TEMP2 changes depending on the opening degree of the first hot water flow path opening / closing portion 22. For example, when the opening degree of the first hot water flow path opening / closing part 22 is in the range of 0 to 100, and the hot water flow path temperature TEMP2 measured when the opening degree is 100 is 50 ° C., the opening degree is 50. The hot water channel temperature TEMP2 to be measured is lower than 50 ° C, for example 40 ° C. Here, assuming that the first predetermined temperature A = 50 ° C., if a failure occurs when the opening degree of the first hot water flow path opening / closing portion 22 is 100, an abnormal state can be determined, but the failure occurs when the opening degree is 50. In that case, the abnormal state cannot be determined. Further, when the first predetermined temperature A = 40 ° C. is set, the valve of the first hot water flow path opening / closing portion 22 is closed when there is a possibility that the space behind the ceiling becomes a high temperature of 40 ° C. or higher such as in summer. Even if it is normal, it may be a false positive. That is, it is not possible to make a correct determination only by determining the abnormal state based on the hot water flow path temperature TEMP2. Therefore, a relative comparison between the air temperature TEMP1 and the hot water flow path temperature TEMP2 is performed.

空気温度測定部１９と温水流路温度測定部２３は、本体ケース２の内周側空間に配置されている。このため、第一温水流路開閉部が正しく閉状態となれば、温水流路温度ＴＥＭＰ２と空気温度ＴＥＭＰ１はほぼ等しい値となる。これに対して、第一温水流路開閉部２２の弁が正しく閉状態とならず、つまり第一温水流路２０に温水が流れてしまう状態となっていると、温水流路温度ＴＥＭＰ２が空気温度ＴＥＭＰ１より高くなる。たとえ温水の漏れ量が少ない場合であっても、温水流路温度ＴＥＭＰ２は空気温度ＴＥＭＰ１より高い値となるので、空気温度ＴＥＭＰ１と温水流路温度ＴＥＭＰ２との間に温度差があれば、第一温水流路開閉部２２が異常状態であることがわかる。 The air temperature measuring unit 19 and the hot water flow path temperature measuring unit 23 are arranged in the inner peripheral side space of the main body case 2. Therefore, if the first hot water flow path opening / closing portion is properly closed, the hot water flow path temperature TEMP2 and the air temperature TEMP1 become substantially equal values. On the other hand, if the valve of the first hot water flow path opening / closing portion 22 is not properly closed, that is, the hot water flows into the first hot water flow path 20, the hot water flow path temperature TEMP2 becomes air. The temperature is higher than TEMP1. Even if the amount of hot water leakage is small, the hot water flow path temperature TEMP2 is higher than the air temperature TEMP1, so if there is a temperature difference between the air temperature TEMP1 and the hot water flow path temperature TEMP2, the first It can be seen that the hot water flow path opening / closing portion 22 is in an abnormal state.

このように、空気温度測定部１９と温水流路温度測定部２３を同等の温度環境下に配置し、それぞれの温度測定部により測定される温度を相対比較することで、温水の漏れ量や環境温度によらず、第一温水流路開閉部２２の正常状態と異常状態を判定することができるのである。 In this way, by arranging the air temperature measuring unit 19 and the hot water flow path temperature measuring unit 23 in the same temperature environment and comparing the temperatures measured by the respective temperature measuring units relative to each other, the amount of hot water leakage and the environment It is possible to determine the normal state and the abnormal state of the first hot water flow path opening / closing unit 22 regardless of the temperature.

第二状態判定部３６ｄによる異常状態の判定方法も、第一状態判定部３６ｃと同様の考え方である。 The method of determining the abnormal state by the second state determination unit 36d is the same concept as that of the first state determination unit 36c.

また、第一状態判定部３６ｃは、第一温水流路開閉部２２の異常状態を判定するために第二所定時間ＴＩＭＥ２、第三所定時間ＴＩＭＥ３という時間判定を用いている。これにより、空気温度測定部１９と温水流路温度測定部２３により測定される温度のバラつきに起因した誤判定を抑制する効果が期待できる。同様に、第二状態判定部３６ｄも、第二温水流路開閉部２４の異常状態を判定するために第四所定時間ＴＩＭＥ４、第五所定時間ＴＩＭＥ５という時間判定を用いている。 Further, the first state determination unit 36c uses the time determination of the second predetermined time TIME2 and the third predetermined time TIME3 in order to determine the abnormal state of the first hot water flow path opening / closing unit 22. As a result, the effect of suppressing erroneous determination due to temperature variation measured by the air temperature measuring unit 19 and the hot water flow path temperature measuring unit 23 can be expected. Similarly, the second state determination unit 36d also uses the time determination of the fourth predetermined time TIME4 and the fifth predetermined time TIME5 in order to determine the abnormal state of the second hot water flow path opening / closing unit 24.

また、第一温水流路開閉部２２と第二温水流路開閉部２４のうち少なくとも一方の異常状態をリモコン３３に備わる報知部３５によって報知することにより、使用者に対して視覚や聴覚を通して正確に伝えることが可能である。 Further, by notifying the abnormal state of at least one of the first hot water flow path opening / closing unit 22 and the second hot water flow path opening / closing unit 24 by the notification unit 35 provided in the remote controller 33, the user is accurately visually and audibly notified. It is possible to tell to.

また、異常状態が解消されているにもかかわらず、異常状態の報知が継続されていると使用者にとって不快となる。そこで、第一状態判定部３６ｃは、温水流路温度ＴＥＭＰ２を用いて第一温水流路開閉部２２の異常状態を判定する場合には、第一所定温度Ａ以下となれば第一温水流路開閉部２２は正常状態と判定し、異常状態の報知を停止する。また、第一温度差ΔＴ１を用いて第一温水流路開閉部２２の異常状態を判定する場合には、第二所定温度Ｂ以下となれば第一温水流路開閉部２２は正常状態と判定し、制御部３６は、異常状態の報知を停止する。第二状態判定部３６ｄも同様に、第二温水流路開閉部２４が正常状態であると判定した場合、制御部３６は、異常状態の報知を停止する。これにより、リモコン３３へ異常状態の報知を停止するためのリセットボタン等を備える必要がなくなるので、リモコン３３の省スペース化を図ることができる。また、使用者にリセット操作を行わせる負担が発生することを抑制する効果も期待できる。 In addition, it is unpleasant for the user if the notification of the abnormal state is continued even though the abnormal state has been resolved. Therefore, when the first state determination unit 36c determines the abnormal state of the first hot water flow path opening / closing unit 22 by using the hot water flow path temperature TEMP2, the first hot water flow path is the first hot water flow path if the temperature becomes A or less. The opening / closing unit 22 determines that it is in a normal state, and stops notifying the abnormal state. Further, when determining the abnormal state of the first hot water flow path opening / closing part 22 using the first temperature difference ΔT1, it is determined that the first hot water flow path opening / closing part 22 is in a normal state when the second predetermined temperature B or less is determined. Then, the control unit 36 stops the notification of the abnormal state. Similarly, when the second state determination unit 36d determines that the second hot water flow path opening / closing unit 24 is in a normal state, the control unit 36 stops notifying the abnormal state. As a result, it is not necessary to provide the remote controller 33 with a reset button or the like for stopping the notification of the abnormal state, so that the space of the remote controller 33 can be saved. In addition, it can be expected to have an effect of suppressing the burden of causing the user to perform the reset operation.

なお、温水流路温度測定部２３は、第一温水流路２０を通る温水の温度を直接測定するため、第一温水流路２０を構成する配管の内周面側に配置されてもよい。 The hot water flow path temperature measuring unit 23 may be arranged on the inner peripheral surface side of the pipe constituting the first hot water flow path 20 in order to directly measure the temperature of the hot water passing through the first hot water flow path 20.

なお、受熱水流路温度測定部２６は、受熱した水道水の温度を直接測定するため、受熱水流路２５を構成する配管の内周面側に配置されてもよい。 Since the temperature receiving water flow path temperature measuring unit 26 directly measures the temperature of the received tap water, the heat receiving water flow path temperature measuring unit 26 may be arranged on the inner peripheral surface side of the pipe constituting the heat receiving water flow path 25.
