When the state parameter is in a state where an erroneous connection determination is necessary, and the detection temperature of the hot water temperature detection unit is equal to or higher than a predetermined temperature, the determination by the erroneous connection determination unit is performed.
It has the structure of.

これにより、制御部の構成要素として、記憶部に記憶した状態パラメータを有し、誤接続判定部は、状態パラメータが誤接続判定必要な状態で、かつ、温水温度検知部の検知温度が所定の温度以上となった場合に誤接続判定を行うことにより、誤接続判定の実施忘れや不要な誤接続判定の実施を防ぐことができ、適切なタイミングで誤接続の判定ができるという効果を得られる。   As a result, the control unit has the state parameter stored in the storage unit, the erroneous connection determination unit is in a state in which the state parameter requires the erroneous connection determination, and the detected temperature of the hot water temperature detection unit is a predetermined value. By making an incorrect connection determination when the temperature is higher than the temperature, it is possible to prevent an erroneous connection determination from being forgotten or an unnecessary erroneous connection determination being performed, and an effect that an incorrect connection can be determined at an appropriate timing can be obtained. .

以下、本発明の実施の形態について図面を参照しながら説明する。なお、以下の実施の形態は、本発明を具体化した一例であって、本発明の技術的範囲を限定するものではない。また、全図面を通して、同一の部位については同一の符号を付して二度目以降の説明を省略している。さらに、各図面において、本発明に直接には関係しない各部の詳細については説明を省略している。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. The following embodiments are examples embodying the present invention, and do not limit the technical scope of the present invention. In addition, throughout the drawings, the same portions are denoted by the same reference numerals, and the second and subsequent descriptions are omitted. Furthermore, in each drawing, the description of the details of each part not directly related to the present invention is omitted.

(Embodiment 1)
FIG. 1 is a perspective view of a bathroom in which a bathroom heater / dryer is installed, and FIG. 2 is a configuration diagram showing the interior of the bathroom heater / dryer.

図1に示すように、浴室暖房乾燥機本体1は、浴室2の天井面に設置される。また、図2に示すように、浴室暖房乾燥機本体1は、往路温水配管3aと復路温水配管3bを介して熱源機4と接続される。熱源機4からは、往路温水配管3aを通じて温水が供給され、復路温水配管3bを通じて熱源機4へ温水が戻される。浴室暖房乾燥機本体1は、温水温度検知部5と、送風部6と、風路変更部7と、加熱部8とを備えている。また、図2の矢印は風の流れる方向を示している。温水温度検知部5は、温度センサであり、熱源機4から往路温水配管3aを通じて供給される温水の温度、すなわち加熱部8へ流入する温水の温度を検知する。送風部6は、モータによって駆動するファンであり、浴室2内の空気を循環送風する循環ファン6aと、浴室2内の空気を浴室2外へ排出する換気ファン6bとの2種類のファンからなる。風路変更部7はダンパであり、ダンパを開くことによって浴室2内の空気と換気ファン6bとをつなぐ風路が開放される。この状態で換気ファン6bを駆動することにより、浴室2内の空気を外部へ排出する。加熱部8は、熱動弁9と、温水コイル10とからなる。熱源機4から供給される温水は、熱動弁9を開くことにより、温水コイル10内に供給され、熱動弁9を閉じることにより、温水コイル10内へ供給されなくなる。浴室2内の空気を暖める場合は、熱動弁9を開き、温水コイル10内に温水が供給されている状態で、循環ファン6aによって浴室2内の空気を循環させる。これにより、温水コイル10の温水と空気との間で熱交換が行われ、加熱された空気が浴室2内に送り込まれる。このとき、風路変更部7を開き、換気ファン6bを駆動させると、加熱された空気の一部は風路変更部7を通じて外部へ排出される。温水コイル10内の温水は、復路温水配管3bを通って熱源機4へと戻る。   As shown in FIG. 1, the bathroom heater / dryer body 1 is installed on the ceiling surface of the bathroom 2. Moreover, as shown in FIG. 2, the bathroom heating / drying machine main body 1 is connected to the heat source unit 4 via the forward hot water piping 3a and the return hot water piping 3b. Warm water is supplied from the heat source unit 4 through the forward hot water piping 3a, and the hot water is returned to the heat source unit 4 through the return hot water piping 3b. The bathroom heater / dryer main body 1 includes a hot water temperature detection unit 5, a blower unit 6, an air path change unit 7, and a heating unit 8. Moreover, the arrow of FIG. 2 has shown the direction through which a wind flows. The hot water temperature detection unit 5 is a temperature sensor, and detects the temperature of the hot water supplied from the heat source device 4 through the forward hot water piping 3a, that is, the temperature of the hot water flowing into the heating unit 8. The air blower 6 is a fan driven by a motor, and includes two types of fans: a circulation fan 6 a that circulates and blows air in the bathroom 2, and a ventilation fan 6 b that discharges the air in the bathroom 2 to the outside of the bathroom 2. . The air path changing unit 7 is a damper, and the air path connecting the air in the bathroom 2 and the ventilation fan 6b is opened by opening the damper. By driving the ventilation fan 6b in this state, the air in the bathroom 2 is discharged to the outside. The heating unit 8 includes a thermal valve 9 and a hot water coil 10. The hot water supplied from the heat source unit 4 is supplied into the hot water coil 10 by opening the thermal valve 9, and is not supplied into the hot water coil 10 by closing the thermal valve 9. In order to warm the air in the bathroom 2, the thermal valve 9 is opened, and the air in the bathroom 2 is circulated by the circulation fan 6 a while the hot water is supplied into the hot water coil 10. Thereby, heat exchange is performed between the hot water of the hot water coil 10 and the air, and the heated air is sent into the bathroom 2. At this time, when the air path changing unit 7 is opened and the ventilation fan 6 b is driven, a part of the heated air is discharged to the outside through the air path changing unit 7. The hot water in the hot water coil 10 returns to the heat source unit 4 through the return hot water pipe 3b.

次に、図3を用いて制御部11の動作について説明する。図3は、浴室暖房乾燥機の構成を示すブロック図である。   Next, the operation of the control unit 11 will be described with reference to FIG. FIG. 3 is a block diagram showing the configuration of the bathroom heating dryer.

図3に示すように、浴室暖房乾燥機本体1は、制御部11の指示によって送風部6と加熱部8の動作を制御する。加熱部8の加熱を開始する場合は、制御部11が熱動弁9を開くよう指示することにより、温水が供給され、浴室2内の空気の加熱が可能となる。また、制御部11は、リモコン12との通信により、リモコン12からの運転指示によって浴室暖房乾燥機本体1の運転の開始や停止といった運転状態の変更や、リモコン12の表示について指示を行う。さらに、制御部11は、熱源機4との通信により、運転状態に基づく熱源機4への温水の要求や、熱源機4の指示による浴室暖房乾燥機本体1の運転状態の変更等を行う。   As shown in FIG. 3, the bathroom heating / drying machine main body 1 controls the operations of the air blowing unit 6 and the heating unit 8 according to instructions from the control unit 11. When the heating of the heating unit 8 is started, the control unit 11 instructs to open the thermal valve 9 so that hot water is supplied and the air in the bathroom 2 can be heated. In addition, the control unit 11 instructs the change of the operation state such as the start and stop of the operation of the bathroom heater / dryer main body 1 and the display of the remote controller 12 by the operation instruction from the remote controller 12 through communication with the remote controller 12. Furthermore, the control part 11 performs the request | requirement of the hot water to the heat source machine 4 based on a driving | running state, the change of the driving | running state of the bathroom heating dryer main body 1 by the instruction | indication of the heat source machine 4 by communication with the heat source machine 4.

このような浴室暖房乾燥機において、施工時に誤って、往路温水配管3aを浴室暖房乾燥機の温水流出側へ、復路温水配管3bを浴室暖房乾燥機の温水流入側へ、それぞれ接続した場合に、誤接続を検出し、施工者に報知する機能を備えたものが知られている。これは、温水配管の流入側と流出側とを誤って接続した場合、暖房能力の低下が発生するため、施工者に誤接続を知らせ、是正を促すための機能である。   In such a bathroom heater / dryer, when connecting the outgoing hot water pipe 3a to the hot water outflow side of the bathroom heater / dryer and the return hot water pipe 3b to the hot water inflow side of the bathroom heater / dryer by mistake during construction, What has the function to detect a misconnection and to notify an installer is known. This is a function for notifying the builder of the erroneous connection and prompting the correction because the heating capacity is lowered when the inflow side and the outflow side of the hot water pipe are connected by mistake.

従来、このような機能は、配管工事終了後の試運転時に誤接続を判定するものが知られている。しかし、そのような構成では、施工者が試運転を実施しなかった場合には誤接続の判定が行われない。また、試運転では、通信やファンの動作等も含めて機器の動作を確認するため、配管の接続以外の構成に不具合があり、再度試運転が必要となる場合がある。その場合、試運転時に必ず誤接続の判定をする構成では、本来は不要な誤接続の判定を再度行うこととなる。   Conventionally, such a function is known in which erroneous connection is determined at the time of trial operation after the completion of piping work. However, in such a configuration, the erroneous connection is not determined when the installer does not perform the trial run. Further, in the trial operation, since the operation of the device including the communication and the operation of the fan is confirmed, there is a problem in the configuration other than the connection of the piping, and the trial operation may be necessary again. In such a case, in a configuration in which erroneous connection determination is always performed during a trial operation, erroneous connection determination that is originally unnecessary is performed again.

そこで、本実施の形態1においては、浴室暖房乾燥機本体1は、誤接続判定を行った際に判定結果を記憶し、誤接続判定が必要な状態で、かつ、誤接続判定可能な状態となった場合に、誤接続判定を行う。つまり、誤接続判定が必要という情報が記憶されている状態で、電源投入後、初めて温水が供給されている状態となった場合に、誤接続判定を行う構成とする。   Therefore, in the first embodiment, the bathroom heating / drying machine main body 1 stores the determination result when the erroneous connection determination is performed, and is in a state where the erroneous connection determination is necessary and the erroneous connection determination is possible. In such a case, an erroneous connection determination is performed. In other words, when the information indicating that the erroneous connection determination is necessary is stored and the hot water is supplied for the first time after the power is turned on, the erroneous connection determination is performed.

以下、誤接続判定の処理について説明する。   Hereinafter, the erroneous connection determination process will be described.

図3において、制御部11は、誤接続判定部13と、記憶部14とを備えている。誤接続判定部13は、温水温度検知部5の検知温度変化によって、温水配管の流入側である往路温水配管3aと流出側である復路温水配管3bとの誤接続を判定する。温水温度検知部5は、既存の構成において、浴室暖房乾燥機本体1の保護や異常検知などの目的で往路温水配管3aに温度センサが設けられている場合は、その温度センサを利用することができる。記憶部14は、電源を切っても記憶した内容が消えない不揮発性の記憶領域であり、EEPROMやマイコン内蔵の不揮発性メモリなどである。記憶部14は、記憶内容の一つとして、誤接続判定部13の判定結果を記憶する状態パラメータ16を持つ。状態パラメータ16は、誤接続判定が必要な状態かどうかを判断するための記憶値である。例えば、1つの数値ごとに対応する状態を割り当て、0:「未判定」、1:「誤接続」、2:「正常接続」の3種類の数値や、0:「誤接続判定必要」、1:「誤接続判定不要」の2種類の数値などで表現することができる。誤接続判定部13は、状態パラメータ16の記憶値が、誤接続判定必要な状態、すなわち、前述の例では、「未判定」または、「誤接続」または、「誤接続判定必要」の場合には誤接続判定を行い、その他の場合には誤接続判定を行わないものとする。また、誤接続判定部13の判定結果は、表示部15に表示される。表示部15は、浴室暖房乾燥機本体1の運転を操作するリモコン12を用いることで、既存の構成から構成要素を追加することなく、施工者に分かりやすく判定結果を報知することができる。   In FIG. 3, the control unit 11 includes an erroneous connection determination unit 13 and a storage unit 14. The erroneous connection determination unit 13 determines an erroneous connection between the forward hot water piping 3a on the inflow side of the hot water piping and the return hot water piping 3b on the outflow side based on a change in the detected temperature of the hot water temperature detection unit 5. In the existing configuration, when the temperature sensor is provided in the outbound hot water piping 3a for the purpose of protecting the bathroom heating / drying machine body 1 or detecting an abnormality in the existing configuration, the hot water temperature detection unit 5 can use the temperature sensor. it can. The storage unit 14 is a nonvolatile storage area in which stored contents are not lost even when the power is turned off, and is an EEPROM, a nonvolatile memory built in a microcomputer, or the like. The storage unit 14 has a state parameter 16 for storing the determination result of the erroneous connection determination unit 13 as one of the stored contents. The state parameter 16 is a stored value for determining whether or not an erroneous connection determination is necessary. For example, a state corresponding to each numerical value is assigned, and 0: “not determined”, 1: “wrong connection”, 2: “normal connection”, 0: “misconnection determination required”, 1 : It can be expressed by two types of numerical values such as “no erroneous connection determination required”. The erroneous connection determination unit 13 is in a state where the stored value of the state parameter 16 requires an erroneous connection determination, that is, in the above-described example, “undetermined”, “incorrect connection”, or “incorrect connection determination required”. Performs an incorrect connection determination, and does not perform an incorrect connection determination in other cases. The determination result of the erroneous connection determination unit 13 is displayed on the display unit 15. By using the remote controller 12 that operates the operation of the bathroom heating / drying machine main body 1, the display unit 15 can easily notify the installer of the determination result without adding a component from the existing configuration.

以下、誤接続判定を実施する際の処理の流れの詳細について、図4、図5を用いて説明する。図4、図5は、浴室換気乾燥機の誤接続判定制御の動作を示すフローチャートである。また、ここでは、状態パラメータ16の記憶値として、0:「誤接続判定必要」、1:「誤接続判定不要」の2種類の数値で表現する場合の例を示す。   Hereinafter, the details of the flow of processing when performing erroneous connection determination will be described with reference to FIGS. 4 and 5. 4 and 5 are flowcharts showing the operation of erroneous connection determination control of the bathroom ventilation dryer. Here, an example is shown in which the stored values of the state parameter 16 are expressed by two types of numerical values of 0: “wrong connection determination required” and 1: “wrong connection determination unnecessary”.

浴室暖房乾燥機本体1に電源が投入されると、制御部11は、温水温度検知部5の検知温度の取得を開始する。図4のアルゴリズムAに示すように、誤接続判定部13では、記憶部14から状態パラメータ16の値を読み出す。状態パラメータ16の値が誤接続判定必要な状態、すなわち、「誤接続判定必要」を意味する「0」が記憶されている場合は、以下の誤接続判定の処理を実施する。誤接続判定が不要な状態、すなわち、「誤接続判定不要」を意味する「1」が記憶されている場合は誤接続判定の制御を解除し、以下の処理は行わない。浴室暖房乾燥機本体1の出荷時には、状態パラメータ16は「誤接続判定必要」を意味する「0」が記憶されている。そのため、施工後初めて浴室暖房乾燥機本体1に電源を投入した際は、必ず誤接続判定必要と判断されることとなる。   When the bathroom heating / drying machine main body 1 is turned on, the control unit 11 starts to acquire the detected temperature of the hot water temperature detecting unit 5. As shown in algorithm A of FIG. 4, the erroneous connection determination unit 13 reads the value of the state parameter 16 from the storage unit 14. If the value of the state parameter 16 is in a state where an erroneous connection determination is necessary, that is, “0” meaning “incorrect connection determination necessary” is stored, the following erroneous connection determination processing is performed. When the erroneous connection determination is not necessary, that is, when “1” meaning “misconnection determination unnecessary” is stored, the control of the erroneous connection determination is canceled and the following processing is not performed. At the time of shipment of the bathroom heating / drying machine main body 1, “0”, which means “necessary connection determination necessary”, is stored in the state parameter 16. For this reason, when power is supplied to the bathroom heater / dryer main body 1 for the first time after the construction, it is always determined that an erroneous connection determination is necessary.

誤接続判定が必要な状態であった場合、誤接続判定部13では、図4のアルゴリズムB1に示すように、温水温度検知部5の検知温度が所定の値Ta以上になるまで待機する。所定の値Taは、熱源機4から温水が供給されていないときの温度より高い値であり、熱源機4から温水が供給されたことを判別可能な最低限の温度である。また、ここでの待機中は通常時と同様、リモコン12や熱源機4による運転、または試運転の指示を受け付けられる状態となる。ここで、リモコン12または熱源機4からの指示により、温風を必要とする運転(例えば暖房運転)が開始された場合、制御部11の指示で熱動弁9を開くことにより、往路温水配管3aを通じて熱源機4から浴室暖房乾燥機本体1内に温水が供給されることとなる。このとき、温水温度検知部5の検知温度は、温水の供給が継続すると、ある時点で所定の値Ta以上となる。これにより、アルゴリズムB1の最初の条件を満たすため、通常の暖房運転の制御は一旦停止し、誤接続判定を優先して行う。誤接続判定の手順として、最初に送風部6における送風を停止し、温水温度検知部5の検知温度が十分上昇する時間待機する。ここで、熱交換開始前温度T1として、温水と空気の間で熱交換が行われていない状態における温水温度検知部5の検知温度を取得する。その後、送風部6において、循環ファン6a、換気ファン6bの一方または両方による送風を開始し、一定時間待機する。ここで、熱交換開始後温度T2として、温水と空気の間で熱交換が行われている状態における温水温度検知部5の検知温度を取得する。この際、往路温水配管3aと復路温水配管3bが、それぞれ浴室暖房乾燥機本体1の流入側、流出側に正しく接続されていた場合、温水温度検知部5は、熱交換前の温水である往路温水配管3a側の温度を検知することになる。そのため、検知温度は送風部6による送風の開始前後で大きく変化することはない。しかし、往路温水配管3aと復路温水配管3bが、逆に接続されていた場合、温水温度検知部5は復路温水配管3b側の温度を検知することになる。そのため、送風部6による送風を開始し、温水と空気の間で熱交換が行われると、温水温度検知部5は、熱交換後の温度が下がった温水の温度を検知することとなる。これにより、熱交換開始前温度T1と熱交換開始後温度T2の温度差が、誤接続時の温度変化の基準値である所定の閾値Th1より小さければ誤接続なしと判定し、所定の閾値Th1以上であれば誤接続と判定する。つまり、T1−T2<Th1であれば、接続が正しいと判定し、T1−T2≧Th1であれば、誤接続と判定する。ここで判定した結果は、状態パラメータ16の記憶値として上書きされる。すなわち、接続が正しいと判定された場合は、状態パラメータ16に「誤接続判定不要」を意味する「1」を書き込み、誤接続と判定された場合は、「誤接続判定必要」を意味する「0」を書き込む。   When the erroneous connection determination is necessary, the erroneous connection determination unit 13 waits until the detected temperature of the hot water temperature detection unit 5 becomes equal to or higher than a predetermined value Ta as shown in algorithm B1 of FIG. The predetermined value Ta is a value higher than the temperature when the hot water is not supplied from the heat source unit 4 and is the minimum temperature at which it can be determined that the hot water is supplied from the heat source unit 4. Further, during the standby here, as in the normal state, the operation by the remote controller 12 or the heat source unit 4 or a test operation instruction can be accepted. Here, when an operation requiring hot air (for example, a heating operation) is started by an instruction from the remote controller 12 or the heat source device 4, an outward hot water pipe is opened by opening the thermal valve 9 according to an instruction from the control unit 11. Hot water will be supplied from the heat source 4 into the bathroom heating / drying machine main body 1 through 3a. At this time, the detection temperature of the hot water temperature detection unit 5 becomes equal to or higher than a predetermined value Ta at a certain point in time when the supply of hot water is continued. Thereby, in order to satisfy the first condition of the algorithm B1, normal heating operation control is temporarily stopped, and erroneous connection determination is performed with priority. As an erroneous connection determination procedure, first, the air blowing in the air blowing unit 6 is stopped, and the system waits for a time during which the detected temperature of the hot water temperature detecting unit 5 is sufficiently increased. Here, the temperature detected by the hot water temperature detection unit 5 in a state where heat exchange is not performed between the hot water and air is acquired as the temperature T1 before the start of heat exchange. Then, in the ventilation part 6, ventilation by one or both of the circulation fan 6a and the ventilation fan 6b is started and waits for a certain time. Here, the temperature detected by the hot water temperature detection unit 5 in a state where heat exchange is performed between the hot water and air is acquired as the temperature T2 after the start of heat exchange. At this time, when the forward hot water pipe 3a and the return hot water pipe 3b are correctly connected to the inflow side and the outflow side of the bathroom heater / dryer body 1, respectively, the hot water temperature detection unit 5 is the forward path that is the hot water before heat exchange. The temperature on the hot water pipe 3a side is detected. Therefore, the detected temperature does not change greatly before and after the start of the blowing by the blowing unit 6. However, when the outgoing hot water pipe 3a and the return hot water pipe 3b are connected in reverse, the hot water temperature detector 5 detects the temperature on the return hot water pipe 3b side. Therefore, when the ventilation by the air blowing unit 6 is started and heat exchange is performed between the hot water and the air, the hot water temperature detection unit 5 detects the temperature of the hot water whose temperature after the heat exchange has decreased. Thereby, if the temperature difference between the temperature T1 before the heat exchange start and the temperature T2 after the heat exchange start is smaller than the predetermined threshold Th1 that is a reference value of the temperature change at the time of incorrect connection, it is determined that there is no erroneous connection, and the predetermined threshold Th1. If it is above, it determines with an incorrect connection. That is, if T1-T2 <Th1, it is determined that the connection is correct, and if T1-T2 ≧ Th1, it is determined that the connection is incorrect. The result determined here is overwritten as the stored value of the state parameter 16. That is, when it is determined that the connection is correct, “1” indicating “misconnection determination unnecessary” is written in the state parameter 16, and when it is determined that the connection is incorrect, “incorrect connection determination is necessary”. Write "0".

誤接続判定部13の判定結果は、制御部11により、リモコン12に伝えられる。リモコン12は、表示部15に判定結果を表示する。例えば、通常運転時に7セグメントLCDを用いて運転残時間の表示をしているリモコンでは、7セグメントLCDを用いて数字やアルファベットのエラーコードを表示することで、誤接続と判定されたことを報知できる。このように、リモコン12を用いて判定結果を表示することにより、新たに判定結果を表示させる表示部15を設けることなく、配管の誤接続を施工者に気付かせやすくすることができる。また、誤接続判定中も、判定のための特殊な運転状態であることを報知するため、通常運転時とは異なる表示とすることが望ましい。接続が正しいと判定された場合は、通常時の表示に戻すか、もしくは接続が正常であることを明示的に表現する表示としてもよい。   The determination result of the erroneous connection determination unit 13 is transmitted to the remote controller 12 by the control unit 11. The remote controller 12 displays the determination result on the display unit 15. For example, in a remote control that displays the remaining operation time using a 7-segment LCD during normal operation, a number or alphabetic error code is displayed using the 7-segment LCD to notify that the connection has been determined to be incorrect. it can. In this way, by displaying the determination result using the remote controller 12, it is possible to make it easier for the installer to notice an incorrect connection of the pipe without providing the display unit 15 for newly displaying the determination result. In addition, even during erroneous connection determination, it is desirable to display a display different from that during normal operation in order to notify that the operation state is a special operation state. When it is determined that the connection is correct, the display may be returned to the normal display or may be explicitly expressed that the connection is normal.

状態パラメータ16を記憶している記憶部14は、不揮発性メモリであるため、一旦、浴室暖房乾燥機本体1の電源を遮断した場合でも、記憶内容が保持される。これを利用し、誤接続と判定された場合は、浴室暖房乾燥機本体1の電源を遮断しない限り、誤接続を報知する表示を継続し、運転できないようにすることで、施工者に誤接続の是正を促すことができる。誤接続と判断された場合、施工者は電源を遮断して温水配管の接続を修正した後、再度電源を投入する。このとき、誤接続判定部13では、前述のアルゴリズムAで誤接続判定が必要と判断するため、再度誤接続判定を行うこととなる。一度、接続が正しいと判定され、状態パラメータ16に「誤接続判定不要」を意味する「1」が書き込まれた場合は、それ以降、電源の遮断、電源再投入をしても、誤接続判定をすることはない。   Since the storage unit 14 storing the state parameter 16 is a non-volatile memory, the stored content is retained even when the power supply of the bathroom heating / drying machine main body 1 is once cut off. Using this, if it is determined that the connection is incorrect, unless the power to the bathroom heating / drying machine body 1 is cut off, the display notifying the incorrect connection is continued so that the operation cannot be performed. Can be rectified. When it is determined that the connection is incorrect, the contractor cuts off the power and corrects the hot water pipe connection, and then turns on the power again. At this time, the erroneous connection determination unit 13 performs the erroneous connection determination again because it is determined that the erroneous connection determination is necessary by the algorithm A described above. Once it is determined that the connection is correct and “1” meaning “misconnection determination unnecessary” is written in the status parameter 16, the determination of incorrect connection is made even if the power is turned off and then turned on again. Never do.

このようにして、誤接続判定不要な場合には誤接続判定を行わず、誤接続判定が必要な場合には、確実に誤接続判定を行うことができるため、誤接続判定の実施忘れや、不要な誤接続判定の実施を防ぐことができ、適切なタイミングで誤接続の判定ができる。   In this way, when incorrect connection determination is not necessary, incorrect connection determination is not performed, and when erroneous connection determination is required, erroneous connection determination can be reliably performed. Unnecessary erroneous connection determination can be prevented, and erroneous connection determination can be performed at an appropriate timing.

次に、図5を用いて、誤接続判定の別の処理の例を示す。図5は、図4における、アルゴリズムB1の部分をアルゴリズムB2に置き換えたものである。   Next, another example of erroneous connection determination processing will be described with reference to FIG. FIG. 5 is obtained by replacing algorithm B1 in FIG. 4 with algorithm B2.

図5において、アルゴリズムAの部分と、アルゴリズムB2の温水温度検知部5の検知温度が所定の値Ta以上となるのを待機する部分までは、図4と同様の流れである。アルゴリズムB2では、温水温度検知部5の検知温度が所定の値Ta以上となった際、送風部6による送風が行われていた場合は送風を継続し、送風が行われていなかった場合は送風を開始する。ここで、温水温度が上昇するのに十分な時間待機した後、熱交換開始後温度T3として、温水と空気の間で熱交換が行われている状態における温水温度検知部5の検知温度を取得する。この際、アルゴリズムB1の場合と同様の原理で、往路温水配管3aと復路温水配管3bが正しく接続されていた場合は、温水と空気の間で熱交換が行われているかどうかに関わらず、温水温度検知部5の検知温度は熱源機4から供給された往路温水配管3a側の温水の温度を検知することになる。そのため、時間の経過とともに温水温度検知部5の検知温度は、誤接続時の最高検知温度より高い所定の閾値Th2を超える。一方、誤って接続されていた場合は、温水温度検知部5は熱交換後の温度が下がった温水の温度である復路温水配管3b側の温度を検知することになるため、所定の時間経過後も所定の閾値Th2を超えない。これにより、熱交換開始後温度T3が所定の閾値Th2より大きい場合に接続が正しいと判断する。つまり、T3>Th2の場合は接続が正しいと判定し、T3≦Th2の場合は誤接続と判定する。判定結果の状態パラメータ16への書き込み、判定結果の表示については、アルゴリズムB1で説明したものと同様である。   In FIG. 5, the flow is the same as that in FIG. 4 until the part of algorithm A and the part waiting for the detected temperature of the hot water temperature detector 5 of algorithm B2 to be equal to or higher than a predetermined value Ta. In the algorithm B2, when the temperature detected by the hot water temperature detection unit 5 is equal to or higher than a predetermined value Ta, the blowing is continued if the blowing by the blowing unit 6 is performed, and the blowing is performed if the blowing is not performed. To start. Here, after waiting for a sufficient time for the hot water temperature to rise, the temperature detected by the hot water temperature detection unit 5 in the state where heat exchange is performed between the hot water and air is obtained as the temperature T3 after the start of heat exchange. To do. At this time, when the outgoing hot water pipe 3a and the return hot water pipe 3b are correctly connected according to the same principle as in the algorithm B1, the hot water is used regardless of whether heat is exchanged between the hot water and the air. The temperature detected by the temperature detection unit 5 detects the temperature of the hot water supplied from the heat source unit 4 on the outgoing hot water pipe 3a side. Therefore, with the passage of time, the detected temperature of the hot water temperature detector 5 exceeds a predetermined threshold Th2 that is higher than the highest detected temperature at the time of erroneous connection. On the other hand, when it is connected by mistake, the hot water temperature detector 5 detects the temperature of the return hot water pipe 3b side, which is the temperature of the hot water whose temperature after heat exchange has dropped, and therefore after a predetermined time has elapsed. Does not exceed the predetermined threshold Th2. Thus, it is determined that the connection is correct when the temperature T3 after the start of heat exchange is higher than the predetermined threshold Th2. That is, when T3> Th2, it is determined that the connection is correct, and when T3 ≦ Th2, it is determined that the connection is incorrect. The writing of the determination result to the state parameter 16 and the display of the determination result are the same as those described in the algorithm B1.

以上のようにして、図5の処理においても、誤接続判定不要な場合には誤接続判定を行わず、誤接続判定が必要な場合には、確実に誤接続判定を行うことができる。   As described above, also in the process of FIG. 5, the erroneous connection determination is not performed when the erroneous connection determination is unnecessary, and the erroneous connection determination can be reliably performed when the erroneous connection determination is necessary.

本発明にかかる浴室暖房乾燥機は、熱源機と接続する温水配管の誤接続を判定する機能において、誤接続判定不要な場合には誤接続判定を行わず、誤接続判定が必要な場合にのみ、誤接続判定を行うものであり、温水との熱交換によって空気を加熱する浴室暖房乾燥機等として有用である。   The bathroom heater / dryer according to the present invention is a function for determining an erroneous connection of a hot water pipe connected to a heat source device, and does not perform an erroneous connection determination when an erroneous connection determination is not necessary, and only when an erroneous connection determination is necessary. It is used for erroneous connection determination, and is useful as a bathroom heating dryer or the like that heats air by heat exchange with hot water.
