Description

【発明の属する技術分野】
本発明は、主に浴室の天井や天井裏などに設置され、浴室空気を循環するための循環ファンと該環ファンを駆動する循環モータからなる循環用送風機と浴室空気を換気するための換気ファンと換気ファンを駆動する換気モータからなる換気用送風機と浴室空気を再び浴室内へ吐出させるルーバーとルーバーを開閉するための駆動手段と循環ファンとルーバーの間の循環風路と循環風路に設けた加熱手段と循環風路の温度を検知する温度検出手段とを備えた浴室空調装置に関する。
【0002】
【従来の技術】
従来、この種の浴室空調装置は、ルーバーの故障を検知するために、ルーバー駆動部に位置センサーなどの検知手段を設けていた。運転時にルーバーが故障して所定の位置にルーバーがないことを位置センサーで検知すると、浴室空調装置の運転を停止し浴室空調装置本体が高温になるのを防止していた。(例えば、特許文献1参照。)。
【0003】
【特許文献1】
特開平8−313033号公報
【0004】
【発明が解決しようとする課題】
しかしながら、上記従来のものでは、ルーバーの故障を検知するために、特別にルーバーの位置を検出する位置センサーなどの部品を設置する必要があるため、コストが高くなっていた。
【0005】
また、またルーバーの位置を検出する位置センサーの付加により部品点数が増えるため、浴室乾燥装置本体の重量が重くなり、天井や壁に取り付けた状態では建築躯体に負荷がかかり、また、重量が重いため施工時の負担になることがあった。
【0006】
本発明は、上記課題を解決するためになされたもので、本発明の目的は、位置センサーなどの特別な部品を追加することなく安価にルーバーの故障を検知することができ、また、部品点数を減らすことができる浴室空調装置を提供することにある。
【0007】
【課題を解決するための手段及び作用・効果】
循環モータの駆動により循環ファンを回転させて浴室の空気を吸気口から吸気し、該空気を再び浴室内に吹出口から吹出す循環風路と、換気ファンにより浴室の空気を排気口から屋外へ排気する排気風路と、前記循環風路内に配設した加熱手段および前記循環風路の温度を検知する温度検出手段と、前記吹出口に配設した駆動手段により吹出口を開閉させるルーバーと、前記循環ファン、換気ファン、加熱手段およびルーバーを制御する制御部とを備えた浴室空調装置において、前記制御部は、前記循環モータは回転数一定制御を行うとともに、所定回転数の駆動に対応した入力電圧に基づく前記循環風路の圧力損失を推定し、前記圧力損失と温度検出手段の出力とに応じて、前記ルーバーの駆動手段の故障検知することとした。
【0008】
これにより、ルーバーの位置を検出する位置センサーなどの特別な部品を用いることなくルーバーの故障を検知できるようになり、ルーバーが故障してルーバーが閉状態のまま暖房運転や乾燥運転が行なわれ製品内部が加熱されることを防止することができる。
【0009】
さらに、浴室空調装置の温度検出手段は、運転開始時と運転開始から一定時間経過後の温度差を検出することとした。
こうすることによって、外気温度が変化しても一定時間経過後の循環風路内の温度は異なるが、初期温度からの温度差は一定なので循環風路内の温度上昇を正確に素早く把握できるようになる。
【0010】
さらに、浴室空調装置の循環モータは回転数一定制御運転を行い、あらかじめ記憶しておいた循環モータ運転時の循環モータ入力電圧と実際に運転している時の循環モータ入力電圧の差を検出するこで圧力損失の情報を得ることを特徴としている。
こうすることによって、ルーバーの位置を検出する位置センサーなどの特別な装置を追加することなく循環風路の圧力損失の状態を把握することができるようになる。
【0011】
【発明の実施の形態】
以下に、本発明の実施の形態を添付図面に基づいて説明する。
【0012】
図1は、本発明の第1実施形態を示す断面図である。浴室空調装置の本体1には、換気用送風機3が上段と循環用送風機4が下段に配設されている。本体1の浴室13へ開口した部分は化粧カバー2が取付けられている。
換気用送風機は換気モータ32によって換気ファン31を駆動して送風し、吸気口6から吸気された空気は排気風路9を通って排気口5を通って屋外等へ排気される。
循環用送風機は循環モータ42によって循環ファン41を駆動して送風し、浴室13の空気を循環用吸気口44から吸気し、循環風路43、ヒータ14、吹出口46に配設されたルーバー8を通って再び浴室13へ戻るようになっている。なお、循環用吸気口44にはほこり等を吸着させるフィルター45が取り付いている。
【0013】
制御部(図示せず)により、ルーバー8は、暖房運転と乾燥運転時にはルーバーを開閉させる駆動手段(図示せず)を駆動させることによりルーバー8は開いた状態となり浴室13へ風を送るように制御される。また、暖房運転と乾燥運転時以外の換気運転等の場合には、ルーバー8はルーバー駆動手段(図示せず)によって閉じた状態となるように制御される。
また、暖房運転時には、循環用送風機4のみを動作させ、浴室13の空気を循環吸気口44から吸気しヒータ14にて加熱し、循環風路43、ルーバー8を通って再び浴室13へ戻し浴室13を暖房するように制御される。
また、乾燥運転時には、循環用送風機4を動作させ、浴室13の空気をヒータ14にて加熱し、循環風路43、ルーバー8を通って再び浴室13へ戻し浴室13の衣類(図示せず)に温風を当て、同時に換気用送風機3も動作させ、浴室13の湿った空気が排気口5を通じて外へ排気することで乾燥運転ができるようにように制御される。
また、暖房運転と乾燥運転時には、循環風路43内の温度をサーミスタ7にて測定し、設定温度より高くなるとヒータ14への入力を減らすなどの制御を行なっている。
また、換気運転時には、換気用送風機3を動作させ、浴室13の空気を吸気口6から吸気し、排気口5を通じて外へ排気できるように制御している。
【0014】
図2は、暖房運転と乾燥運転時における循環風路43内の温度を示している。運転開始からt時間経過後の循環風路43内の温度は正常状態の時はT1となる。フィルター45がほこりなどで詰まり循環風路内が閉塞した状態、ルーバー8が故障して閉になった状態、循環モータ42が故障して循環ファン41が回らない状態の各ケースにおいて、循環風路43内の温度はそれぞれT2、T3、T4となる。フィルター45がほこりなどで詰まり循環風路内が閉塞した状態では正常状態と比較して循環風路43を流れる風量が減るため循環風路43の温度が上昇しT2の状態となる。また、ルーバー8が故障して閉状態となると、循環風路43の風量が減り、温度がさらに上昇しT3となる。あるいは、循環モータ42が故障して循環ファン41が回らない状態となると、循環風路43に風が流れなくなるため、循環風路43の温度は急激に上がりT4となる。
【0015】
図3は、暖房運転と乾燥運転時における循環モータ入力電圧と循環モータの回転数を示している。
運転時の循環モータ42の回転数はNとなるように回転数制御をおこなうため、循環風路43の圧力損失状態によって循環モータ入力電圧が変化する。運転時の正常状態では循環モータの入力電圧はV1の状態となる。フィルター45がほこりなどで詰まり循環風路内が閉塞した状態およびルーバー8が故障して閉になった状態の循環モータ入力電圧は、それぞれV2、V3となる。
フィルター45がほこりなどで詰まり循環風路内が閉塞した状態では、正常状態と比較して循環風路43内の圧力損失が大きくなるため、循環モータ入力電圧が低くなりV2となる。
ルーバー8が故障して閉状態となると、さらに循環風路43の圧力損失が大きくなり、循環モータ入力電圧がさらに低くなりV3となる。
【0016】
図4は、ルーバー故障検知を行なうフロー図である。
まず、暖房運転と乾燥運転開始からt時間経過後の循環風路43内の温度をサーミスタ7で検知する。サーミスタ7を利用し循環風路内の温度を検知することで、特別に部品を追加することなく、ルーバーの故障の可能性があることが検知できるようになる。
検知した温度がT1の場合は正常状態であり、検知した温度がT2、T3、T4の場合はルーバー8が故障している可能性がある。
検知した温度がT2、T3、T4の場合は、次の段階で、現状の循環モータの入力電圧値を検出して循環風路内の圧力損失の情報を参照する。
検知した入力電圧がV1の場合は正常状態であり、V2、V3の場合はルーバー8が故障しているか若しくは循環モータが故障している可能性がある。
そのため、循環モータの入力電圧がV2、V3の場合は、次の段階で制御部からルーバー8を閉状態へ移動させる指令を出し、その時の循環モータの入力電圧を調べる。正常であればルーバー開状態から閉状態へ変化するため、ルーバー8を閉状態へ移動させる指令を出す前後で入力電圧が変化するはずである。
V2、V3の入力電圧の値に変化がない場合はルーバー8が故障したものと認識することができる。
またこのとき、V2、V3が変化して入力電圧が低くなるようであるとフィルター45がほこり等で詰まり、循環風路が閉塞していると認識することができる。
またこのとき、循環モータ42を回転させるための入力電圧をかけても循環モータ42からの回転数情報が一定にならない場合は循環モータが故障したものと認識することができる。
このように、循環モータの入力電圧がV2、V3の場合は、ルーバーを閉状態へ移動させる指令を出し、その時の循環モータの入力電圧を調べV2、V3の値に変化がない場合は、ルーバー故障と断定でき、V2、V3が変化して入力電圧が低くなるようであるとフィルターがほこり等で詰まり循環風路が閉塞していると断定できる。
以上のように、既設の温度検出装置および循環モータを用いて、循環風路の温度を検知し、循環モータへの入力に対応した循環風路の圧力損失をみることで、高価なセンサーを用いることなく簡単にルーバーの駆動手段の故障を検知することができる。

The present invention mainly provides a circulation fan, which is installed on a ceiling or a space above a ceiling of a bathroom and includes a circulation fan for circulating bathroom air and a circulation motor for driving the ring fan, and a ventilation fan for ventilating bathroom air. A ventilation blower consisting of a ventilation motor that drives a ventilation fan, a louver that discharges bathroom air into the bathroom again, a drive means for opening and closing the louver, and a circulation air passage between the circulation fan and the louver and a circulation air passage The present invention relates to a bathroom air conditioner provided with a heating means and a temperature detecting means for detecting a temperature of a circulation air passage.
[0002]
[Prior art]
Conventionally, this type of bathroom air conditioner has provided a detecting means such as a position sensor in a louver drive unit in order to detect a failure of the louver. When the position sensor detects that the louver has failed and there is no louver at a predetermined position during operation, the operation of the bathroom air conditioner is stopped to prevent the temperature of the bathroom air conditioner body from becoming high. (For example, refer to Patent Document 1).
[0003]
[Patent Document 1]
JP-A-8-313033
[Problems to be solved by the invention]
However, in the above-described conventional device, components such as a position sensor for specifically detecting the position of the louver need to be installed in order to detect a failure of the louver, so that the cost is high.
[0005]
In addition, the addition of a position sensor that detects the position of the louver increases the number of components, which increases the weight of the bathroom drying device body, and places a heavy load on the building frame when it is mounted on the ceiling or wall. As a result, there was a case that it was burdensome at the time of construction.
[0006]
The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to detect a failure of a louver at low cost without adding a special part such as a position sensor. It is an object of the present invention to provide a bathroom air conditioner that can reduce the amount of air conditioning.
[0007]
[Means for Solving the Problems and Functions / Effects]
The circulation fan is rotated by driving the circulation motor to take in the air in the bathroom from the air inlet, and the air is again blown into the bathroom from the outlet, and the air in the bathroom is discharged from the air outlet to the outside by the ventilation fan. An exhaust air path for exhausting, a heating means disposed in the circulation air path, a temperature detection means for detecting the temperature of the circulation air path, and a louver for opening and closing the air outlet by a driving means arranged in the air outlet. In a bathroom air-conditioning apparatus including a circulating fan, a ventilation fan, a control unit for controlling a heating unit and a louver, the control unit controls the circulating motor to perform constant rotation speed control while driving the circulation motor at a predetermined rotation speed. The pressure loss of the circulating air passage is estimated based on the corresponding input voltage, and the failure of the driving means of the louver is detected according to the pressure loss and the output of the temperature detecting means.
[0008]
As a result, louver failure can be detected without using special components such as a position sensor for detecting the position of the louver, and a heating operation or a drying operation is performed while the louver is broken and the louver is closed. The inside can be prevented from being heated.
[0009]
Further, the temperature detecting means of the bathroom air conditioner detects a temperature difference between a time when the operation is started and a time after a lapse of a predetermined time from the start of the operation.
In this way, even if the outside air temperature changes, the temperature in the circulation air passage after a certain period of time differs, but the temperature difference from the initial temperature is constant, so that the temperature rise in the circulation air passage can be accurately and quickly grasped. become.
[0010]
In addition, the circulation motor of the bathroom air conditioner performs a constant rotation speed control operation and detects the difference between the previously stored circulation motor input voltage during circulation motor operation and the circulation motor input voltage during actual operation. In this way, information on pressure loss is obtained.
This makes it possible to grasp the state of pressure loss in the circulation air passage without adding a special device such as a position sensor for detecting the position of the louver.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.
[0012]
FIG. 1 is a sectional view showing a first embodiment of the present invention. In the main body 1 of the bathroom air conditioner, a ventilation blower 3 is arranged in an upper stage and a circulation blower 4 is arranged in a lower stage. A decorative cover 2 is attached to a portion of the main body 1 that opens to the bathroom 13.
The ventilation blower drives the ventilation fan 31 by the ventilation motor 32 to blow air, and the air taken in from the intake port 6 is exhausted to the outside through the exhaust air path 9, the exhaust port 5, and the like.
The circulating blower drives the circulating fan 41 by the circulating motor 42 to blow air, and draws air from the bathroom 13 from the circulating air inlet 44, and the louver 8 provided in the circulating air passage 43, the heater 14, and the outlet 46. And returns to the bathroom 13 again. In addition, a filter 45 for adsorbing dust and the like is attached to the circulation intake port 44.
[0013]
The control unit (not shown) causes the louver 8 to be in an open state by driving a driving means (not shown) for opening and closing the louver during the heating operation and the drying operation so that the louver 8 is blown to the bathroom 13. Controlled. In the case of a ventilation operation other than the heating operation and the drying operation, the louver 8 is controlled to be in a closed state by louver driving means (not shown).
Also, during the heating operation, only the circulation blower 4 is operated, the air in the bathroom 13 is sucked in from the circulation intake port 44 and heated by the heater 14, returned to the bathroom 13 through the circulation air passage 43 and the louver 8, and returned to the bathroom 13. 13 is controlled to be heated.
During the drying operation, the circulating blower 4 is operated, the air in the bathroom 13 is heated by the heater 14, and then returned to the bathroom 13 through the circulating air passage 43 and the louver 8, so that the clothes (not shown) in the bathroom 13 are provided. , And the ventilation blower 3 is operated at the same time, so that the drying operation can be performed by exhausting the humid air in the bathroom 13 to the outside through the exhaust port 5.
During the heating operation and the drying operation, the temperature in the circulation air passage 43 is measured by the thermistor 7, and when the temperature becomes higher than the set temperature, control such as reducing the input to the heater 14 is performed.
Also, during ventilation operation, the ventilation blower 3 is operated to control the air in the bathroom 13 to be sucked in from the air inlet 6 and exhausted to the outside through the air outlet 5.
[0014]
FIG. 2 shows the temperature in the circulation air passage 43 during the heating operation and the drying operation. After the elapse of the time t from the start of the operation, the temperature in the circulation air passage 43 is T1 in a normal state. In each case where the filter 45 is clogged with dust or the like and the inside of the circulating air passage is closed, the louver 8 is broken and closed, and the circulating motor 42 is broken and the circulating fan 41 does not rotate, the circulating air passage is used. The temperatures in 43 are T2, T3, and T4, respectively. In a state in which the filter 45 is clogged with dust or the like and the inside of the circulation air passage is closed, the amount of air flowing through the circulation air passage 43 is reduced as compared with the normal state, so that the temperature of the circulation air passage 43 rises to a state of T2. Further, when the louver 8 breaks down and is closed, the air volume in the circulation air passage 43 decreases, and the temperature further rises to T3. Alternatively, if the circulation motor 42 fails and the circulation fan 41 does not rotate, the air does not flow through the circulation air passage 43, and the temperature of the circulation air passage 43 rapidly rises to T4.
[0015]
FIG. 3 shows the circulation motor input voltage and the rotation speed of the circulation motor during the heating operation and the drying operation.
Since the rotation speed is controlled so that the rotation speed of the circulation motor 42 during operation becomes N, the circulation motor input voltage changes depending on the pressure loss state of the circulation air passage 43. In a normal state during operation, the input voltage of the circulating motor is at V1. The circulating motor input voltages when the filter 45 is clogged with dust or the like and the inside of the circulating air passage is closed, and when the louver 8 is broken and closed are V2 and V3, respectively.
In a state where the filter 45 is clogged with dust or the like and the inside of the circulation air passage is closed, the pressure loss in the circulation air passage 43 becomes large as compared with the normal state, so that the input voltage of the circulation motor decreases to V2.
When the louver 8 is broken and closed, the pressure loss in the circulation air passage 43 further increases, and the input voltage of the circulation motor further decreases to V3.
[0016]
FIG. 4 is a flowchart for performing louver failure detection.
First, the thermistor 7 detects the temperature in the circulation air passage 43 after the elapse of the time t from the start of the heating operation and the drying operation. By using the thermistor 7 to detect the temperature in the circulating air passage, it is possible to detect the possibility of louver failure without adding any special components.
When the detected temperature is T1, the state is normal, and when the detected temperatures are T2, T3, and T4, the louver 8 may have failed.
When the detected temperatures are T2, T3, and T4, in the next stage, the current input voltage value of the circulation motor is detected, and information on the pressure loss in the circulation air passage is referred to.
If the detected input voltage is V1, it is normal, and if it is V2, V3, there is a possibility that the louver 8 has failed or the circulating motor has failed.
Therefore, when the input voltage of the circulation motor is V2 or V3, a command to move the louver 8 to the closed state is issued from the control unit in the next stage, and the input voltage of the circulation motor at that time is examined. If it is normal, the louver changes from the open state to the closed state, so that the input voltage should change before and after issuing a command to move the louver 8 to the closed state.
If there is no change in the input voltage values of V2 and V3, it can be recognized that the louver 8 has failed.
Also, at this time, if V2 and V3 change to decrease the input voltage, it can be recognized that the filter 45 is clogged with dust or the like and the circulation air passage is blocked.
At this time, if the rotation speed information from the circulation motor 42 does not become constant even when the input voltage for rotating the circulation motor 42 is applied, it can be recognized that the circulation motor has failed.
Thus, when the input voltage of the circulating motor is V2 or V3, a command to move the louver to the closed state is issued, and the input voltage of the circulating motor at that time is checked. It can be determined that a failure has occurred. If V2 and V3 change and the input voltage seems to be low, it can be determined that the filter is clogged with dust or the like and the circulation air passage is blocked.
As described above, using the existing temperature detection device and the circulation motor, the temperature of the circulation air passage is detected, and the pressure loss of the circulation air passage corresponding to the input to the circulation motor is used to use an expensive sensor. The failure of the louver drive means can be easily detected without any trouble.
