Description

浴室乾燥機Bathroom Dryer
　本開示は、携帯端末からの遠隔操作が可能な浴室乾燥機に関する。 This disclosure relates to a bathroom dryer that can be remotely controlled from a mobile terminal.
　従来の浴室乾燥機としては、遠隔からリモートコントローラで製品の操作および製品の周囲温度を確認可能としたシステムが知られている。特許文献１には、インタフェースであるホームゲートウェイとさまざまな電気機器とを互いに接続したホームネットワークと、サーバと、が外部通信回線を介して接続され、ホームネットワーク外の端末と各電気機器との通信をサーバを介して可能としたシステムが開示されている。特許文献１に記載のシステムでは、屋外またはホームネットワークが構築されている屋内において使用される携帯端末からの指示が各電気機器へ送られることによって、各電気機器を操作することができる。 As a conventional bathroom dryer, a system that enables remote control of product operation and confirmation of product ambient temperature is known. In Patent Document 1, a home network in which a home gateway as an interface and various electric devices are connected to each other and a server are connected via an external communication line, and communication between a terminal outside the home network and each electric device is provided. Is disclosed as a system that enables this via a server.

特開２００４－４０２８５号公報Japanese Unexamined Patent Publication No. 2004-40285
　上記特許文献１に記載のシステムを、家庭において使用される電気機器の１つである浴室乾燥機に適用すると、携帯端末からの指示を受信することによって、運転の開始、運転の切り換え、または運転の停止といった動作と、電気機器が検知している浴室内の温度である浴室内温度の取得と、を行い得る。特許文献１に記載のシステムでは、遠隔操作による電気機器からの浴室内温度の取得において、特に暖房運転時に、浴室内温度の取得頻度が低いと、実際の浴室内温度と、サーバ上に格納されている浴室内温度と、の差が大きくなり、正確な浴室内温度を把握できない可能性がある。この場合、浴室を使用する使用者の快適さが損なわれるといった不都合が生じることがある。一方で、常時、浴室内温度の取得頻度を高くし過ぎると、実際の浴室内温度とサーバ上に格納されている浴室内温度との差は小さくなるが、通信量が増え、サーバにおけるソフトウエアの動作負荷が高くなり、動作不具合の要因となる可能性があった。このように、特許文献１に記載のシステムを浴室乾燥機に適用した場合には、浴室内温度の取得の頻度を低くしても、また高くしても、不都合が生じ得るという問題があった。 When the system described in Patent Document 1 is applied to a bathroom dryer, which is one of the electric devices used in a home, the operation is started, the operation is switched, or the operation is performed by receiving an instruction from a mobile terminal. It is possible to perform an operation such as stopping the operation and to acquire the temperature in the bathroom, which is the temperature in the bathroom detected by the electric device. In the system described in Patent Document 1, in the acquisition of the bathroom temperature from an electric device by remote operation, if the acquisition frequency of the bathroom temperature is low, especially during the heating operation, the actual bathroom temperature and the actual bathroom temperature are stored on the server. The difference between the temperature inside the bathroom and the temperature inside the bathroom becomes large, and it may not be possible to accurately grasp the temperature inside the bathroom. In this case, inconveniences such as impairing the comfort of the user who uses the bathroom may occur. On the other hand, if the acquisition frequency of the bathroom temperature is always too high, the difference between the actual bathroom temperature and the bathroom temperature stored on the server will be small, but the amount of communication will increase and the software on the server will increase. The operating load of the server became high, which could cause malfunctions. As described above, when the system described in Patent Document 1 is applied to a bathroom dryer, there is a problem that inconvenience may occur even if the frequency of acquisition of the bathroom temperature is low or high. ..
　本開示は、上記に鑑みてなされたものであって、遠隔操作によって浴室内温度を含む浴室乾燥機の運転状態を確認する場合に、実際の浴室内温度に近い浴室内温度を遠隔操作を行う操作者に提供することができるとともに、従来に比して運転状態情報を送信する際の通信量を抑制することができる浴室乾燥機を得ることを目的とする。 The present disclosure has been made in view of the above, and when the operating state of the bathroom dryer including the bathroom temperature is confirmed by remote operation, the bathroom temperature close to the actual bathroom temperature is remotely controlled. It is an object of the present invention to obtain a bathroom dryer that can be provided to an operator and can suppress the amount of communication when transmitting operating state information as compared with the conventional case.
　上述した課題を解決し、目的を達成するために、本開示の浴室乾燥機は、本体部と、操作部と、通信部と、を備える。本体部は、浴室から空気を取り込み、取り込んだ空気である吸気を浴室へと循環させ、あるいは浴室が設けられる建築物の外部に排気する送風機と、吸気の温度を検出する温度検出部と、吸気を加熱する加熱部と、浴室乾燥機に関して設定された内容を示す設定情報にしたがって、送風機および加熱部を制御する制御部と、を有する。操作部は、建築物と同じ屋内に設置され、本体部への操作を受け付ける。通信部は、浴室乾燥機とネットワークを介して接続されるサーバとの間で通信する。制御部は、本体部が第１状態にある場合に、予め定められた基準となる通信間隔である基準通信間隔で温度検出部で検出された温度情報を含む運転状態情報をサーバに送信し、本体部が第１状態とは異なる第２状態にある場合に、運転状態情報を前回送信してから基準通信間隔よりも短い間隔で運転状態情報をサーバに送信する。 In order to solve the above-mentioned problems and achieve the purpose, the bathroom dryer of the present disclosure includes a main body unit, an operation unit, and a communication unit. The main body has a blower that takes in air from the bathroom and circulates the intake air that is taken in to the bathroom, or exhausts it to the outside of the building where the bathroom is installed, a temperature detector that detects the temperature of the intake air, and an intake air. It has a heating unit for heating and a control unit for controlling the blower and the heating unit according to the setting information indicating the contents set for the bathroom dryer. The operation unit is installed indoors in the same room as the building and accepts operations on the main unit. The communication unit communicates between the bathroom dryer and the server connected via the network. When the main body unit is in the first state, the control unit transmits the operation state information including the temperature information detected by the temperature detection unit at the reference communication interval, which is a predetermined reference communication interval, to the server. When the main body is in the second state different from the first state, the operation state information is transmitted to the server at intervals shorter than the reference communication interval after the last transmission of the operation state information.
　本開示にかかる浴室乾燥機は、遠隔操作によって浴室内温度を含む浴室乾燥機の運転状態を確認する場合に、実際の浴室内温度に近い浴室内温度を遠隔操作を行う操作者に提供することができるとともに、従来に比して運転状態情報を送信する際の通信量を抑制することができるという効果を奏する。 The bathroom dryer according to the present disclosure shall provide the operator who remotely operates the bathroom temperature close to the actual bathroom temperature when confirming the operating state of the bathroom dryer including the bathroom temperature by remote operation. At the same time, it has the effect of suppressing the amount of communication when transmitting the operating state information as compared with the conventional case.

　実施の形態１では、制御部１０５は、浴室１１１から取り込んだ空気の温度を温度センサ１０４から取得し、運転モードに応じて定められた送信頻度で、取得した温度である温度情報をクラウドサーバ５に送信する。以下では、温度センサ１０４で測定された温度は、浴室内温度と称される。浴室内温度の送信は、無線ＬＡＮアダプタ３およびブロードバンドルータ４を介して行われる。 In the first embodiment, the control unit 105 acquires the temperature of the air taken in from the bathroom 111 from the temperature sensor 104, and outputs the temperature information which is the acquired temperature at the transmission frequency determined according to the operation mode to the cloud server 5. Send to. Hereinafter, the temperature measured by the temperature sensor 104 is referred to as the bathroom temperature. The transmission of the temperature in the bathroom is performed via the wireless LAN adapter 3 and the broadband router 4.
　図３は、実施の形態１による浴室乾燥機に設けられる制御部の機能構成の一例を模式的に示すブロック図である。なお、図３では、実施の形態１の機能に関する処理部のみを示している。制御部１０５は、温度センサ１０４から浴室内温度を取得する温度取得部１５１と、浴室乾燥機２に設定された設定情報を記憶する設定情報記憶部１５２と、浴室乾燥機２の運転状態を示す運転状態情報を無線ＬＡＮアダプタ３およびブロードバンドルータ４を介してクラウドサーバ５に送信する運転状態情報送信部１５３と、を備える。運転状態情報は、浴室乾燥機２の動作の状態と、浴室内温度と、を含む。 FIG. 3 is a block diagram schematically showing an example of the functional configuration of the control unit provided in the bathroom dryer according to the first embodiment. Note that FIG. 3 shows only the processing unit related to the function of the first embodiment. The control unit 105 shows the operating state of the temperature acquisition unit 151 that acquires the temperature inside the bathroom from the temperature sensor 104, the setting information storage unit 152 that stores the setting information set in the bathroom dryer 2, and the bathroom dryer 2. It includes an operation status information transmission unit 153 that transmits operation status information to the cloud server 5 via the wireless LAN adapter 3 and the broadband router 4. The operating state information includes the operating state of the bathroom dryer 2 and the temperature inside the bathroom.
　運転状態情報送信部１５３は、本体部７が第１状態にある場合に、予め定められた基準となる通信間隔である基準通信間隔で、温度センサ１０４で検出された浴室内温度を含む運転状態情報をクラウドサーバ５に送信する。また、運転状態情報送信部１５３は、本体部７が第１状態とは異なる第２状態にある場合に、運転状態情報を前回送信してから基準通信間隔よりも短い間隔で運転状態情報をクラウドサーバ５に送信する。 The operation state information transmission unit 153 is an operation state including the bathroom temperature detected by the temperature sensor 104 at a reference communication interval which is a predetermined reference communication interval when the main body 7 is in the first state. Information is transmitted to the cloud server 5. Further, when the main body 7 is in the second state different from the first state, the operation state information transmission unit 153 cloud-uses the operation state information at intervals shorter than the reference communication interval after the last transmission of the operation state information. Send to server 5.
　暖房モード時にはヒータ１０３によって浴室１１１内の空気が加熱されるので、浴室内温度が短時間で変化する可能性がある。このため、実施の形態１では、暖房モードの場合と、停止モード、乾燥モードおよび換気モードの場合と、で浴室内温度のクラウドサーバ５への送信頻度を異ならせる。以下では、停止モード、乾燥モードおよび換気モードの場合は通常時と称される。すなわち、第１状態が通常時の場合となり、第２状態が暖房モードの場合となる。 In the heating mode, the air in the bathroom 111 is heated by the heater 103, so that the temperature in the bathroom may change in a short time. Therefore, in the first embodiment, the frequency of transmitting the bathroom temperature to the cloud server 5 is different between the heating mode and the stop mode, the drying mode, and the ventilation mode. In the following, the stop mode, the dry mode and the ventilation mode are referred to as normal times. That is, the first state is the normal state, and the second state is the heating mode.
　実施の形態１において、運転状態情報送信部１５３は、通常時では、基準通信間隔で運転状態情報を送信し、暖房モードでは、基準通信間隔よりも短い通信間隔で運転状態情報を送信する。つまり、暖房モードにおける浴室内温度のクラウドサーバ５への送信頻度は、暖房モード以外の通常時における場合よりも高くされる。一例では、通常時では、５分に１回の送信頻度とし、暖房運転時では３０秒に１回の送信頻度とすることができる。この場合、暖房モードの送信頻度は、通常時の送信頻度の１０倍程度とされる。また、通信間隔で見た場合には、暖房モードの通信間隔は、基準通信間隔の１０分の１の通信間隔となる。 In the first embodiment, the operation state information transmission unit 153 transmits the operation state information at the reference communication interval in the normal time, and transmits the operation state information at the communication interval shorter than the reference communication interval in the heating mode. That is, the frequency of transmitting the temperature in the bathroom to the cloud server 5 in the heating mode is higher than in the normal time other than the heating mode. In one example, the transmission frequency can be set to once every 5 minutes in the normal state and once every 30 seconds in the heating operation. In this case, the transmission frequency in the heating mode is about 10 times the transmission frequency in the normal state. Further, when viewed in terms of communication intervals, the communication interval in the heating mode is one tenth of the reference communication interval.

In step S1, the mobile terminal 6 accepts an operation for starting the heating operation. The operation for starting the heating operation is an operation of pressing the heating button 61b. In step S2, the mobile terminal 6 transmits an instruction to start the heating operation to the cloud server 5.

In step S3, as shown in FIG. 7, the mobile terminal 6 displays a message 62 of “instructing heating operation” on the operation screen 60 indicating that the heating operation has been instructed.
　ステップＳ４において、クラウドサーバ５は、携帯端末６から送信された暖房運転開始の指示を受信する。ステップＳ５において、クラウドサーバ５は、暖房運転開始の指示を浴室乾燥機２へ送信する。ステップＳ６において、浴室乾燥機２は、クラウドサーバ５から送信された暖房運転開始の指示を受信する。ステップＳ７において、浴室乾燥機２は、暖房運転開始の指示に従って、暖房運転を開始する。すなわち、暖房モードとなる。 In step S4, the cloud server 5 receives the instruction to start the heating operation transmitted from the mobile terminal 6. In step S5, the cloud server 5 transmits an instruction to start the heating operation to the bathroom dryer 2. In step S6, the bathroom dryer 2 receives the instruction to start the heating operation transmitted from the cloud server 5. In step S7, the bathroom dryer 2 starts the heating operation according to the instruction for starting the heating operation. That is, the heating mode is set.
　暖房運転を開始すると、浴室乾燥機２は、ステップＳ８において、暖房運転が行われていることを示す運転状態情報をクラウドサーバ５へ送信する。運転状態情報は、浴室乾燥機２が現在行っている運転が、換気運転、暖房運転および乾燥運転のいずれであるかを示す情報である。ステップＳ９において、クラウドサーバ５は、浴室乾燥機２から送信された運転状態情報を受信する。ステップＳ１０において、クラウドサーバ５は、受信された運転状態情報を保存する。 When the heating operation is started, the bathroom dryer 2 transmits the operation state information indicating that the heating operation is being performed to the cloud server 5 in step S8. The operation state information is information indicating whether the operation currently performed by the bathroom dryer 2 is a ventilation operation, a heating operation, or a drying operation. In step S9, the cloud server 5 receives the operation state information transmitted from the bathroom dryer 2. In step S10, the cloud server 5 stores the received operation state information.
　携帯端末６は、ステップＳ２において暖房運転開始の指示を送信した後、クラウドサーバ５へのアクセスによって、クラウドサーバ５に保存されている浴室乾燥機２についての運転状態情報の取得を試みる。ステップＳ１０において運転状態情報がクラウドサーバ５に保存された後におけるクラウドサーバ５へのアクセスによって、携帯端末６は、ステップＳ１１において、クラウドサーバ５から運転状態情報を取得する。図８は、実施の形態１による浴室乾燥機を操作する際において携帯端末に表示される操作画面の一例を示す図である。ステップＳ１２において、携帯端末６は、図８に示されるように、浴室内温度を含む運転状態情報の内容を示す「暖房運転中　浴室内温度２０℃」のメッセージ６３を操作画面６０に表示する。 After transmitting the instruction to start the heating operation in step S2, the mobile terminal 6 attempts to acquire the operation state information of the bathroom dryer 2 stored in the cloud server 5 by accessing the cloud server 5. By accessing the cloud server 5 after the operation state information is stored in the cloud server 5 in step S10, the mobile terminal 6 acquires the operation state information from the cloud server 5 in step S11. FIG. 8 is a diagram showing an example of an operation screen displayed on the mobile terminal when operating the bathroom dryer according to the first embodiment. In step S12, as shown in FIG. 8, the mobile terminal 6 displays a message 63 of "during heating operation, bathroom temperature 20 ° C." on the operation screen 60, which indicates the content of the operation state information including the bathroom temperature.
　携帯端末６は、暖房ボタン６１ｂが押下されてから、暖房運転が行われていることを示す運転状態情報を受信するまでの間において、図７に示されるように、操作画面６０に「暖房運転指示中」のメッセージ６２を表示する。外部操作を行った操作者は、メッセージ６２を目視することによって、浴室乾燥機２へ暖房運転が指示されていることを認識することができる。 As shown in FIG. 7, the mobile terminal 6 has a "heating operation" on the operation screen 60 from the time when the heating button 61b is pressed until the operation state information indicating that the heating operation is being performed is received. "Instructing" message 62 is displayed. The operator who has performed the external operation can recognize that the bathroom dryer 2 is instructed to perform the heating operation by visually observing the message 62.
　携帯端末６は、暖房運転が開始されると、図８に示されるように、操作画面６０に「暖房運転中　浴室内温度２０℃」のメッセージ６３を表示する。操作者は、メッセージ６３を目視することによって、浴室乾燥機２が暖房運転を開始したことおよび浴室内温度を認識することができる。 When the heating operation is started, the mobile terminal 6 displays a message 63 of "during heating operation, bathroom temperature 20 ° C." on the operation screen 60, as shown in FIG. By visually observing the message 63, the operator can recognize that the bathroom dryer 2 has started the heating operation and the temperature in the bathroom.
　浴室乾燥機２、クラウドサーバ５および携帯端末６の間における通信に何らかのトラブルがあった場合、または浴室乾燥機２にエラーが発生した場合などにおいて、暖房運転が正常に開始されないことがあり得る。暖房運転が正常に開始されない場合、暖房運転が行われていることを示す運転状態情報は、携帯端末６において受信されない。暖房ボタン６１ｂが押下されてから、あらかじめ設定された時間、例えば１分間において運転状態情報が受信されなかった場合に、携帯端末６は、暖房運転が開始されなかったことを示すメッセージを操作画面６０に表示してもよい。操作者は、メッセージを目視することによって、浴室乾燥機２による暖房運転が開始されなかったことを認識することができる。 If there is some trouble in the communication between the bathroom dryer 2, the cloud server 5 and the mobile terminal 6, or if an error occurs in the bathroom dryer 2, the heating operation may not be started normally. When the heating operation is not normally started, the operation state information indicating that the heating operation is being performed is not received by the mobile terminal 6. If the operation status information is not received within a preset time, for example, one minute after the heating button 61b is pressed, the mobile terminal 6 displays a message indicating that the heating operation has not been started on the operation screen 60. It may be displayed in. By visually recognizing the message, the operator can recognize that the heating operation by the bathroom dryer 2 has not been started.
　上記したように、クラウドサーバ５には、浴室乾燥機２から受信された運転状態情報が保存される。携帯端末６は、クラウドサーバ５に保存されている運転状態情報を取得して、運転状態情報の内容を示すメッセージ６２，６３を操作画面６０に表示する。これにより、携帯端末６は、操作画面６０に表示されるメッセージ６２，６３の内容を、浴室乾燥機２の実際の運転状態に正確に合わせることができる。 As described above, the cloud server 5 stores the operation status information received from the bathroom dryer 2. The mobile terminal 6 acquires the operation state information stored in the cloud server 5 and displays the messages 62 and 63 indicating the contents of the operation state information on the operation screen 60. As a result, the mobile terminal 6 can accurately match the contents of the messages 62 and 63 displayed on the operation screen 60 with the actual operating state of the bathroom dryer 2.
　携帯端末６において上記アプリケーションが起動されている間、携帯端末６は、浴室乾燥機２についてクラウドサーバ５に保存されている運転状態情報を取得するためのクラウドサーバ５へのアクセスを一定時間おきに行う。携帯端末６は、クラウドサーバ５へのアクセスによって、運転状態情報を取得する。 While the above application is started on the mobile terminal 6, the mobile terminal 6 accesses the cloud server 5 for acquiring the operation state information stored in the cloud server 5 for the bathroom dryer 2 at regular intervals. conduct. The mobile terminal 6 acquires operating state information by accessing the cloud server 5.
　なお、浴室乾燥機２、クラウドサーバ５および携帯端末６は、換気ボタン６１ａまたは乾燥ボタン６１ｃが押下された場合も、暖房ボタン６１ｂが押下された場合と同様の手順により、外部操作に従った動作を行う。 The bathroom dryer 2, the cloud server 5, and the mobile terminal 6 operate according to an external operation by the same procedure as when the heating button 61b is pressed even when the ventilation button 61a or the drying button 61c is pressed. I do.
　換気運転、暖房運転および乾燥運転のいずれかが行われているときに停止ボタン６１ｄが押下された場合、携帯端末６から、クラウドサーバ５を経て浴室乾燥機２へ運転停止指示が送信される。浴室乾燥機２は、運転停止指示に従って、運転を停止する。すなわち、浴室乾燥機２は、停止モードとなる。携帯端末６は、停止ボタン６１ｄが押下されてから、運転停止を指示したことを示すメッセージを操作画面６０に表示する。また、浴室乾燥機２から、クラウドサーバ５を経て携帯端末６へ、運転が停止されたことを示す運転状態情報が送信される。携帯端末６は、運転が停止されたことを示すメッセージを操作画面６０に表示する。 When the stop button 61d is pressed while any of the ventilation operation, the heating operation, and the drying operation is being performed, the operation stop instruction is transmitted from the mobile terminal 6 to the bathroom dryer 2 via the cloud server 5. The bathroom dryer 2 stops the operation according to the operation stop instruction. That is, the bathroom dryer 2 is in the stop mode. After the stop button 61d is pressed, the mobile terminal 6 displays a message indicating that the operation is stopped on the operation screen 60. Further, the operation state information indicating that the operation has been stopped is transmitted from the bathroom dryer 2 to the mobile terminal 6 via the cloud server 5. The mobile terminal 6 displays a message indicating that the operation has been stopped on the operation screen 60.
　図８に示されるように携帯端末６上で浴室内温度を確認するには携帯端末６のアプリケーションがクラウドサーバ５に格納された運転状態情報を取得する必要がある。上記したように、ステップＳ８において、浴室乾燥機２は、クラウドサーバ５に運転状態情報を送信する。また、ステップＳ１１において、携帯端末６は、クラウドサーバ５から運転状態情報を一定時間おきに取得する。特に、暖房モード時の初期には、浴室内温度が短時間で大きく変化することがある。この場合、浴室乾燥機２がクラウドサーバ５に運転状態情報を送信する頻度が、携帯端末６がクラウドサーバ５から運転状態情報を取得する頻度に比して小さいと、携帯端末６の操作画面６０に表示されるメッセージ６３中の浴室内温度と、実際の浴室内温度と、の間で差異が発生する。 As shown in FIG. 8, in order to confirm the temperature in the bathroom on the mobile terminal 6, the application of the mobile terminal 6 needs to acquire the operating state information stored in the cloud server 5. As described above, in step S8, the bathroom dryer 2 transmits the operation state information to the cloud server 5. Further, in step S11, the mobile terminal 6 acquires the operation state information from the cloud server 5 at regular intervals. In particular, in the initial stage of the heating mode, the temperature in the bathroom may change significantly in a short time. In this case, if the frequency with which the bathroom dryer 2 transmits the operation status information to the cloud server 5 is smaller than the frequency with which the mobile terminal 6 acquires the operation status information from the cloud server 5, the operation screen 60 of the mobile terminal 6 There is a difference between the bathroom temperature in the message 63 displayed in and the actual bathroom temperature.
　これを解決するために、実施の形態１では、換気モード、乾燥モードおよび停止モードを含む通常時の場合には、浴室内温度が短時間で変化することはないと考えられるので、ステップＳ８において、浴室乾燥機２の運転状態情報送信部１５３は、基準通信間隔で浴室内温度を含む運転状態情報をクラウドサーバ５へ送信する。一例では、基準通信間隔は、携帯端末６がクラウドサーバ５から運転状態情報を取得する間隔よりも長い。一方、暖房モードの場合には、運転状態情報送信部１５３は、基準通信間隔よりも短い間隔で運転状態情報をクラウドサーバ５へ送信する。つまり、暖房モードの場合の運転状態情報の送信間隔を、通常時の場合に比して高くする。一例では、暖房運転モードの場合の浴室乾燥機２からクラウドサーバ５へ運転状態情報を送信する間隔は、携帯端末６がクラウドサーバ５から運転状態情報を取得する間隔以下とされる。 In order to solve this, in the first embodiment, it is considered that the temperature in the bathroom does not change in a short time in the normal time including the ventilation mode, the drying mode, and the stop mode. Therefore, in step S8. , The operation state information transmission unit 153 of the bathroom dryer 2 transmits the operation state information including the temperature in the bathroom to the cloud server 5 at the reference communication interval. In one example, the reference communication interval is longer than the interval at which the mobile terminal 6 acquires the operation status information from the cloud server 5. On the other hand, in the heating mode, the operation status information transmission unit 153 transmits the operation status information to the cloud server 5 at intervals shorter than the reference communication interval. That is, the transmission interval of the operation state information in the heating mode is set higher than in the normal state. In one example, the interval for transmitting the operation status information from the bathroom dryer 2 to the cloud server 5 in the heating operation mode is set to be equal to or less than the interval for the mobile terminal 6 to acquire the operation status information from the cloud server 5.
　図９は、実施の形態１による浴室乾燥機における運転状態情報の送信制御処理の手順の一例を示すフローチャートである。まず、ステップＳ３１において、浴室乾燥機２の制御部１０５の運転状態情報送信部１５３は、設定情報記憶部１５２から現在の運転モードを取得する。ついで、ステップＳ３２において、運転状態情報送信部１５３は、運転モードが暖房モードであるかを判定する。 FIG. 9 is a flowchart showing an example of a procedure for transmission control processing of operation state information in the bathroom dryer according to the first embodiment. First, in step S31, the operation state information transmission unit 153 of the control unit 105 of the bathroom dryer 2 acquires the current operation mode from the setting information storage unit 152. Then, in step S32, the operation state information transmission unit 153 determines whether the operation mode is the heating mode.
　ステップＳ３２で運転モードが暖房モードではない場合（ステップＳ３２でＮｏの場合）、すなわち通常運転である場合には、運転状態情報送信部１５３は、温度取得部１５１で取得した浴室内温度を、基準通信間隔でクラウドサーバ５に送信する（ステップＳ３３）。その後、処理がステップＳ３１に戻る。 When the operation mode is not the heating mode in step S32 (No in step S32), that is, in the normal operation, the operation state information transmission unit 153 uses the bathroom temperature acquired by the temperature acquisition unit 151 as a reference. It is transmitted to the cloud server 5 at the communication interval (step S33). After that, the process returns to step S31.
　ステップＳ３２で運転モードが暖房モードである場合（ステップＳ３２でＹｅｓの場合）には、運転状態情報送信部１５３は、温度取得部１５１で取得した浴室内温度を、基準通信間隔よりも短い間隔でクラウドサーバ５に送信する（ステップＳ３４）。その後、処理がステップＳ３１に戻る。 When the operation mode is the heating mode in step S32 (Yes in step S32), the operation state information transmission unit 153 sets the temperature in the bathroom acquired by the temperature acquisition unit 151 at intervals shorter than the reference communication interval. It is transmitted to the cloud server 5 (step S34). After that, the process returns to step S31.
　以上のように、実施の形態１では、浴室乾燥機２の制御部１０５が、運転モードに応じて、浴室乾燥機２から運転状態情報をクラウドサーバ５に送信する通信間隔を変更した。具体的には、通常時では、基準通信間隔で運転状態情報を送信し、暖房モードの場合には、基準通信間隔よりも短い間隔で運転状態情報を送信する。これによって、浴室内温度が短期間で大きく変動する可能性がある暖房モードの場合には、クラウドサーバ５に記憶される浴室内温度は高頻度で更新されることになる。この結果、携帯端末６で浴室乾燥機２の運転状態情報をクラウドサーバ５から取得して確認した場合に、実際の浴室内温度に近い浴室内温度を携帯端末６の操作画面６０に表示させることができる。 As described above, in the first embodiment, the control unit 105 of the bathroom dryer 2 changes the communication interval for transmitting the operation status information from the bathroom dryer 2 to the cloud server 5 according to the operation mode. Specifically, in the normal time, the operation state information is transmitted at the reference communication interval, and in the heating mode, the operation state information is transmitted at an interval shorter than the reference communication interval. As a result, in the case of the heating mode in which the temperature in the bathroom may fluctuate significantly in a short period of time, the temperature in the bathroom stored in the cloud server 5 is updated frequently. As a result, when the operating state information of the bathroom dryer 2 is acquired from the cloud server 5 and confirmed by the mobile terminal 6, the bathroom temperature close to the actual bathroom temperature is displayed on the operation screen 60 of the mobile terminal 6. Can be done.
　また、暖房モード以外の通常時の場合には、浴室内温度が短期間で大きく変動する可能性が低いので、暖房モードの場合ほど高頻度ではなく、基準通信間隔で浴室内温度を更新する。これによって、運転状態情報の送信頻度を常時高くする必要がなくなる。また、１日のうちで浴室乾燥機２を暖房モードで運転する時間は長くて数時間程度であるので、インターネット回線９における通信量の増加を抑えることができる。また、クラウドサーバ５で運転状態情報を記憶する処理の負荷が高くなってしまうことを抑えることもできる。 Also, in normal times other than the heating mode, the bathroom temperature is unlikely to fluctuate significantly in a short period of time, so the frequency is not as high as in the heating mode, and the bathroom temperature is updated at standard communication intervals. This eliminates the need to constantly increase the frequency of transmission of operation status information. Further, since the time for operating the bathroom dryer 2 in the heating mode in one day is about several hours at the longest, it is possible to suppress an increase in the amount of communication on the Internet line 9. Further, it is possible to prevent the cloud server 5 from increasing the load of the process of storing the operation state information.
　従来では、暖房モードと、暖房モード以外のモードと、で運転状態情報の送信頻度に変更がなかったので、実際の浴室内温度に近い浴室内温度を携帯端末６に提供するには、暖房モードでの送信頻度に合わせて運転状態情報を送信しなければならなかった。この結果、浴室内温度が変化しないような状況でも、インターネット回線９における通信量が増えるとともに、クラウドサーバ５で運転状態情報を記憶する処理に負荷がかかっていた。また、通信量を抑えるために、運転状態情報の送信頻度を低くすると、暖房モード時に短期間で大きく変化する実際の浴室内温度と乖離した浴室内温度が携帯端末６に提供される可能性が高くなる。しかし、実施の形態１では、暖房モードでは、送信頻度を高くし、暖房モード以外のモードでは送信頻度を低くしたので、従来におけるこれらの問題を解決することができる。また、暖房モード時に、実際の浴室内温度と携帯端末６がクラウドサーバ５から取得した浴室内温度との乖離が小さくなるので、浴室を使用する使用者の快適さが損なわれるといった不都合を解消することもできる。 In the past, there was no change in the transmission frequency of the operation status information between the heating mode and the mode other than the heating mode. Therefore, in order to provide the mobile terminal 6 with the bathroom temperature close to the actual bathroom temperature, the heating mode is used. The operation status information had to be transmitted according to the transmission frequency in. As a result, even in a situation where the temperature in the bathroom does not change, the amount of communication on the Internet line 9 increases, and the process of storing the operation state information on the cloud server 5 is burdened. In addition, if the frequency of transmission of operation status information is reduced in order to reduce the amount of communication, there is a possibility that the mobile terminal 6 is provided with a bathroom temperature that deviates from the actual bathroom temperature that changes significantly in a short period of time in the heating mode. It gets higher. However, in the first embodiment, the transmission frequency is increased in the heating mode and the transmission frequency is decreased in the modes other than the heating mode, so that these problems in the prior art can be solved. Further, in the heating mode, the difference between the actual bathroom temperature and the bathroom temperature acquired by the mobile terminal 6 from the cloud server 5 becomes small, which eliminates the inconvenience that the comfort of the user using the bathroom is impaired. You can also do it.
実施の形態２．
　実施の形態１では、運転モードによって運転状態情報の送信頻度を変化させる場合を示した。実施の形態２では、単位時間当たりの浴室内温度の変化量に応じて運転状態情報の送信頻度を変化させる場合を説明する。 Embodiment 2.
In the first embodiment, a case where the transmission frequency of the operation state information is changed depending on the operation mode is shown. In the second embodiment, a case where the transmission frequency of the operating state information is changed according to the amount of change in the temperature in the bathroom per unit time will be described.
　図１０は、暖房運転時の浴室内温度の時間に対する変化の一例を示す図である。図１０において、横軸は、時間を示し、縦軸は、浴室内温度を示している。ここでは横軸の単位は「分」であり、縦軸の単位は「℃」である。図１０に示されるように、暖房モードで浴室乾燥機２を運転させると、設定温度になるまでは、単位時間当たりの浴室内温度の変化量が大きく、設定温度に到達すると、単位時間当たりの浴室内温度の変化量は小さくなる。そこで、実施の形態２では、単位時間当たりの浴室内温度の変化に注目して運転状態情報の通信間隔を変化させる。図１０の領域Ｒ２では、基準通信間隔として送信頻度を低くし、領域Ｒ１では、基準通信間隔よりも短い間隔で運転状態情報を送信し、送信頻度を領域Ｒ２の場合よりも高くする。 FIG. 10 is a diagram showing an example of a change in the temperature in the bathroom with respect to time during the heating operation. In FIG. 10, the horizontal axis represents time and the vertical axis represents the temperature in the bathroom. Here, the unit on the horizontal axis is "minutes", and the unit on the vertical axis is "° C". As shown in FIG. 10, when the bathroom dryer 2 is operated in the heating mode, the amount of change in the bathroom temperature per unit time is large until the set temperature is reached, and when the set temperature is reached, the unit time is reached. The amount of change in the temperature inside the bathroom becomes small. Therefore, in the second embodiment, the communication interval of the operation state information is changed by paying attention to the change in the temperature in the bathroom per unit time. In the area R2 of FIG. 10, the transmission frequency is lowered as the reference communication interval, and in the area R1, the operation state information is transmitted at intervals shorter than the reference communication interval, and the transmission frequency is higher than in the case of the area R2.
　実施の形態２による浴室乾燥機２の構成は、制御部１０５の構成を除いて、実施の形態１で説明したものと同様である。図１１は、実施の形態２による浴室乾燥機に設けられる制御部の機能構成の一例を模式的に示すブロック図である。なお、実施の形態１と同一の構成要素には、同一の符号を付して、その説明を省略する。実施の形態２の制御部１０５は、温度取得部１５１で取得された温度を用いて、単位時間当たりの浴室内温度の変化量を算出する温度変化量算出部１５４をさらに備える。 The configuration of the bathroom dryer 2 according to the second embodiment is the same as that described in the first embodiment except for the configuration of the control unit 105. FIG. 11 is a block diagram schematically showing an example of the functional configuration of the control unit provided in the bathroom dryer according to the second embodiment. The same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted. The control unit 105 of the second embodiment further includes a temperature change amount calculation unit 154 that calculates the amount of change in the bathroom temperature per unit time using the temperature acquired by the temperature acquisition unit 151.
　運転状態情報送信部１５３は、温度変化量算出部１５４で算出された単位時間当たりの浴室内温度の変化を監視し、単位時間当たりの浴室内温度の変化が第１基準値である基準値を下回る場合には、基準通信間隔で運転状態情報を送信する。運転状態情報送信部１５３は、単位時間当たりの浴室内温度の変化量が基準値を上回る場合には、基準通信間隔よりも短い間隔で運転状態情報を送信する。より具体的には、運転状態情報送信部１５３は、運転状態情報を前回送信してから基準通信間隔が経過していない場合でも、単位時間当たりの浴室内温度の変化量が基準値を上回る場合に、運転状態情報を送信する。この場合、実施の形態１で説明した第１状態が、単位時間当たりの浴室内温度の変化量が基準値を下回る場合となり、第２状態が、単位時間当たりの浴室内温度の変化量が基準値を上回る場合となる。なお、単位時間当たりの浴室内温度の変化量が基準値と等しい場合には、運転状態情報の送信頻度を高くしてもよいし、低くしてもよい。 The operation state information transmission unit 153 monitors the change in the bathroom temperature per unit time calculated by the temperature change amount calculation unit 154, and sets a reference value in which the change in the bathroom temperature per unit time is the first reference value. If it is lower than that, the operation status information is transmitted at the reference communication interval. When the amount of change in the bathroom temperature per unit time exceeds the reference value, the operation status information transmission unit 153 transmits the operation status information at intervals shorter than the reference communication interval. More specifically, when the operation status information transmission unit 153 exceeds the reference value in the amount of change in the bathroom temperature per unit time even if the reference communication interval has not elapsed since the last transmission of the operation status information. The operation status information is transmitted to. In this case, in the first state described in the first embodiment, the amount of change in the bathroom temperature per unit time is less than the reference value, and in the second state, the amount of change in the bathroom temperature per unit time is the reference. If it exceeds the value. When the amount of change in the bathroom temperature per unit time is equal to the reference value, the frequency of transmission of the operating state information may be increased or decreased.
　一例では、運転状態情報送信部１５３は、単位時間当たりの浴室内温度の変化が基準値を下回る場合、あるいは単位時間当たりの浴室内温度の変化を算出することができない場合には、５分に１回の送信頻度で、すなわち５分の通信間隔で、運転状態情報を送信する。また、運転状態情報送信部１５３は、単位時間当たりの浴室内温度の変化が基準値を上回る場合には、前回の運転状態情報の送信から５分が経過していなくても、基準値を上回った時点で運転状態情報を送信する。その後、運転状態情報送信部１５３は、運転状態情報を送信した時点から単位時間当たりの浴室内温度の変化を監視する。基準値は、一例では、５分以内に２℃とすることができる。なお、単位時間当たりの浴室内温度の変化が基準値を上回る状態が継続している場合には、基準通信間隔よりも短い予め定められた通信間隔で運転状態情報を送信してもよい。 In one example, if the change in the bathroom temperature per unit time is below the reference value, or if the change in the bathroom temperature per unit time cannot be calculated, the operation state information transmission unit 153 takes 5 minutes. The operation status information is transmitted at one transmission frequency, that is, at a communication interval of 5 minutes. Further, when the change in the bathroom temperature per unit time exceeds the reference value, the operation status information transmission unit 153 exceeds the reference value even if 5 minutes have not passed since the previous transmission of the operation status information. At that point, the operating status information is transmitted. After that, the operation state information transmission unit 153 monitors the change in the temperature in the bathroom per unit time from the time when the operation state information is transmitted. In one example, the reference value can be 2 ° C. within 5 minutes. If the change in the bathroom temperature per unit time continues to exceed the reference value, the operation status information may be transmitted at a predetermined communication interval shorter than the reference communication interval.
　実施の形態２では、単位時間当たりの浴室内温度の変化に注目して、通信間隔を変えるようにした。これによって、暖房モードで運転しているときで、浴室内温度が設定温度に到達するまでは、運転状態情報の通信間隔が短くなるが、浴室内温度が設定温度に到達し、浴室内温度が略変化しなくなった後は、運転状態情報の通信間隔が長くなる。つまり、浴室内温度が略変化しなくなった後でも、実施の形態１のように、高頻度で運転状態情報を送信していると、略変化のない情報の送信に通信資源を費やしてしまうことになるが、実施の形態２では、このような状況が生じることを抑えることができる。なお、実施の形態１と実施の形態２とを組み合わせてもよい。これによって、浴室乾燥機２の動作の中で、浴室内温度の変化量が基準値を上回る場合だけ、運転状態情報の通信間隔を短くするという制御を行うことができる。この結果、実施の形態１の場合に比してさらにインターネット回線９における通信量を抑制することができるとともに、クラウドサーバ５で運転状態情報を記憶する処理にかかる負荷を低減することができる。 In the second embodiment, the communication interval is changed by paying attention to the change in the temperature in the bathroom per unit time. As a result, when operating in the heating mode, the communication interval of the operation status information is shortened until the temperature in the bathroom reaches the set temperature, but the temperature in the bathroom reaches the set temperature and the temperature in the bathroom becomes higher. After the temperature does not change substantially, the communication interval of the operation status information becomes long. That is, even after the temperature in the bathroom does not change substantially, if the operation state information is transmitted frequently as in the first embodiment, communication resources are consumed for transmitting the information that does not change substantially. However, in the second embodiment, it is possible to prevent such a situation from occurring. The first embodiment and the second embodiment may be combined. Thereby, in the operation of the bathroom dryer 2, it is possible to control to shorten the communication interval of the operation state information only when the change amount of the temperature in the bathroom exceeds the reference value. As a result, the amount of communication on the Internet line 9 can be further suppressed as compared with the case of the first embodiment, and the load on the process of storing the operation state information on the cloud server 5 can be reduced.
実施の形態３．
　実施の形態１では、暖房モード以外のモードの場合に、実施の形態２では単位時間当たりの浴室内温度の変化量が基準値よりも小さい場合に、予め定められた通信間隔すなわち送信頻度で運転状態情報を送信していた。このような場合に、浴室内温度がほとんど変化しないこともある。実施の形態３では、このような場合に、運転状態情報の送信をしないようにする場合を説明する。 Embodiment 3.
In the first embodiment, in the case of a mode other than the heating mode, in the second embodiment, when the amount of change in the bathroom temperature per unit time is smaller than the reference value, the operation is performed at a predetermined communication interval, that is, the transmission frequency. I was sending status information. In such a case, the temperature in the bathroom may hardly change. In the third embodiment, a case where the operation state information is not transmitted in such a case will be described.
　実施の形態３による浴室乾燥機２の構成は、実施の形態２で説明したものと同様である。ただし、運転状態情報送信部１５３は、温度変化量算出部１５４で算出された温度の変化量の絶対値が、基準通信間隔内で予め定められた第２基準値である基準値よりも小さい場合には、運転状態情報を送信しない。一例では、基準通信間隔である５分間における浴室内温度の変化量の絶対値が１℃以内である場合、すなわち５分間における浴室内温度の変化量が±１℃以内である場合に、運転状態情報送信部１５３は、運転状態情報を前回送信してから基準通信間隔が経過した後であっても、運転状態情報の送信を行わない。なお、その他の構成は、実施の形態１，２で説明したものと同様であるので、その説明を省略する。 The configuration of the bathroom dryer 2 according to the third embodiment is the same as that described in the second embodiment. However, in the operation state information transmission unit 153, when the absolute value of the temperature change amount calculated by the temperature change amount calculation unit 154 is smaller than the reference value which is the second reference value predetermined within the reference communication interval. Does not send operating status information to. In one example, the operating state is when the absolute value of the change in the bathroom temperature in 5 minutes, which is the reference communication interval, is within 1 ° C, that is, when the change in the bathroom temperature in 5 minutes is within ± 1 ° C. The information transmission unit 153 does not transmit the operation status information even after the reference communication interval has elapsed since the last transmission of the operation status information. Since the other configurations are the same as those described in the first and second embodiments, the description thereof will be omitted.
　実施の形態３では、運転状態情報送信部１５３は、本体部７が第１状態にある場合で、基準通信間隔内における浴室内温度の変化量の絶対値が予め定められた基準値より小さい場合には、運転状態情報を送信しないようにした。これによって、略同じ浴室内温度を基準通信間隔で送信するという状態の発生を抑制し、インターネット回線９の通信量を、実施の形態１，２の場合に比してさらに抑えることができる。また、実施の形態３を実施の形態１，２と組み合わせることも可能である。つまり、第１状態において基準通信間隔内の浴室内温度の変化がほとんどない場合には、運転状態情報を送信させないという制御を行うことができる。これによって、実施の形態１，２の場合に比してさらにインターネット回線９の通信量を抑制し、クラウドサーバ５で運転状態情報を記憶する処理にかかる負荷を低減することができる。 In the third embodiment, the operation state information transmission unit 153 is in the case where the main body unit 7 is in the first state and the absolute value of the amount of change in the bathroom temperature within the reference communication interval is smaller than the predetermined reference value. I did not send the operation status information to. As a result, it is possible to suppress the occurrence of a state in which substantially the same bathroom temperature is transmitted at the reference communication interval, and further suppress the communication amount of the Internet line 9 as compared with the cases of the first and second embodiments. It is also possible to combine the third embodiment with the first and second embodiments. That is, when there is almost no change in the temperature in the bathroom within the reference communication interval in the first state, it is possible to control not to transmit the operation state information. As a result, the communication amount of the Internet line 9 can be further suppressed as compared with the cases of the first and second embodiments, and the load on the process of storing the operation state information on the cloud server 5 can be reduced.
実施の形態４．
　実施の形態１から３では、浴室乾燥機２からクラウドサーバ５への運転状態情報の送信頻度を状況に応じて変えるものであった。実施の形態４では、暖房モードで運転中に浴室内温度を観察することによって浴室１１１の異常を検知する場合を例に挙げる。 Embodiment 4.
In the first to third embodiments, the frequency of transmission of the operation status information from the bathroom dryer 2 to the cloud server 5 is changed according to the situation. In the fourth embodiment, a case where an abnormality in the bathroom 111 is detected by observing the temperature inside the bathroom during operation in the heating mode will be given as an example.
　図１２は、暖房運転時の浴室内温度の時間に対する変化の一例を示す図である。図１２において、横軸は、時間を示し、縦軸は、浴室内温度を示している。ここでは横軸の単位は「分」であり、縦軸の単位は「℃」である。図１２では、暖房を開始してからの浴室内温度の時間変化が示されている。暖房開始時には浴室内温度は５℃であったが、１５分経過後には、１０℃付近となり、それ以上温度が上がらない傾向にある。浴室内温度がこのような挙動を示す場合には、通常、浴室１１１の窓が開いたままで、浴室１１１内に外気が侵入している可能性がある。そこで、実施の形態４では、浴室内温度を監視し、浴室内温度が低い状態から暖房運転を開始したにもかかわらず、浴室内温度が暖房運転を開始した時点から予め定められた時間が経過しても予め定められた温度である基準温度まで到達しない場合に、浴室１１１内に異常があることを操作者に通知する。 FIG. 12 is a diagram showing an example of a change in the temperature in the bathroom with respect to time during the heating operation. In FIG. 12, the horizontal axis represents time and the vertical axis represents the temperature in the bathroom. Here, the unit on the horizontal axis is "minutes", and the unit on the vertical axis is "° C". FIG. 12 shows the time change of the temperature in the bathroom after the start of heating. The temperature in the bathroom was 5 ° C. at the start of heating, but after 15 minutes, it became around 10 ° C., and the temperature tends not to rise any more. When the temperature inside the bathroom exhibits such behavior, it is possible that the outside air has entered the bathroom 111 with the window of the bathroom 111 normally left open. Therefore, in the fourth embodiment, although the bathroom temperature is monitored and the heating operation is started from the state where the bathroom temperature is low, a predetermined time elapses from the time when the bathroom temperature starts the heating operation. Even if it does not reach the reference temperature, which is a predetermined temperature, the operator is notified that there is an abnormality in the bathroom 111.
　実施の形態４による浴室乾燥機２の構成は、制御部１０５の構成を除いて、実施の形態１で説明したものと同様である。図１３は、実施の形態４による浴室乾燥機に設けられる制御部の機能構成の一例を模式的に示すブロック図である。なお、実施の形態１と同一の構成要素には、同一の符号を付して、その説明を省略する。実施の形態４の制御部１０５は、浴室内異常判定部１５５と、確認通知部１５６と、をさらに備える。 The configuration of the bathroom dryer 2 according to the fourth embodiment is the same as that described in the first embodiment except for the configuration of the control unit 105. FIG. 13 is a block diagram schematically showing an example of the functional configuration of the control unit provided in the bathroom dryer according to the fourth embodiment. The same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted. The control unit 105 of the fourth embodiment further includes an abnormality determination unit 155 in the bathroom and a confirmation notification unit 156.
　浴室内異常判定部１５５は、暖房モードのときに、温度取得部１５１で取得された温度を用いて、浴室１１１内の温度の時間変化を監視し、浴室１１１内の異常を判定する。具体的には、浴室内異常判定部１５５は、暖房モードで本体部７の運転が開始されてから予め定められた時間が経過しても、浴室内温度が予め定められた基準温度まで上昇しない場合には、浴室１１１内に異常が発生していると判定する。予め定められた時間としては１５分とすることができるが、これに限定されるものではなく、１０分、２０分または３０分としてもよい。また、基準温度としては、一例では１５℃とすることができる。これらの予め定められた時間および基準温度は、浴室１１１の大きさと浴室乾燥機２の暖房能力とによって定められる。 The bathroom abnormality determination unit 155 monitors the time change of the temperature in the bathroom 111 using the temperature acquired by the temperature acquisition unit 151 in the heating mode, and determines the abnormality in the bathroom 111. Specifically, the bathroom abnormality determination unit 155 does not raise the bathroom temperature to a predetermined reference temperature even after a predetermined time has elapsed since the operation of the main body 7 was started in the heating mode. In this case, it is determined that an abnormality has occurred in the bathroom 111. The predetermined time may be 15 minutes, but is not limited to this, and may be 10 minutes, 20 minutes, or 30 minutes. Further, the reference temperature can be 15 ° C. in one example. These predetermined times and reference temperatures are determined by the size of the bathroom 111 and the heating capacity of the bathroom dryer 2.
　確認通知部１５６は、浴室内異常判定部１５５によって、浴室１１１内に異常が発生していると判定された場合に、浴室１１１に対応付けられる操作者の携帯端末６に浴室１１１内を確認した方がよい旨の通知を無線ＬＡＮアダプタ３およびブロードバンドルータ４を介して送信する。 When the confirmation notification unit 156 determines that an abnormality has occurred in the bathroom 111 by the bathroom abnormality determination unit 155, the confirmation notification unit 156 confirms the inside of the bathroom 111 with the operator's mobile terminal 6 associated with the bathroom 111. A notification to the effect that it is better is transmitted via the wireless LAN adapter 3 and the broadband router 4.
　携帯端末６は、通知を受信すると、通知を通知画面に表示する。図１４は、実施の形態４による浴室乾燥機を操作する際において携帯端末に表示される通知画面の一例を示す図である。図１４に示される通知画面７０は、携帯端末６においてアプリケーションを起動することによって表示される。通知画面７０には、メッセージ７１が表示される。図１４の例では、「浴室内温度が上昇しません　浴室をご確認ください　浴室内温度：○○℃」というメッセージ７１が表示される。これによって、携帯端末６を所持する操作者は、通知を受けた後に、浴室１１１内を確認し、浴室内温度が上昇しないことに関して対処することができる。 When the mobile terminal 6 receives the notification, the mobile terminal 6 displays the notification on the notification screen. FIG. 14 is a diagram showing an example of a notification screen displayed on a mobile terminal when operating the bathroom dryer according to the fourth embodiment. The notification screen 70 shown in FIG. 14 is displayed by invoking an application on the mobile terminal 6. A message 71 is displayed on the notification screen 70. In the example of FIG. 14, the message 71 "The temperature in the bathroom does not rise. Please check the bathroom. Temperature in the bathroom: XX ° C" is displayed. As a result, the operator possessing the mobile terminal 6 can check the inside of the bathroom 111 after receiving the notification and take measures regarding the fact that the temperature inside the bathroom does not rise.
　実施の形態４では、暖房モードで運転を開始してからの浴室内温度が予め定められた時間内に基準温度まで上昇しない場合に、浴室１１１に異常が発生しているとし、操作者の携帯端末６に確認の通知を送信するようにした。これによって、暖房モードで運転しているときに、浴室内温度が上がらない原因となる浴室１１１の窓が開いたままで外気が侵入している可能性を早期に検知することができる。操作者が浴室１１１の近くにいる場合には、浴室１１１を確認して、浴室内温度が上がらない原因を取り除き、操作者が浴室１１１の近くにいない場合には、操作画面６０から暖房モードでの運転を中止することができる。なお、実施の形態４を実施の形態１から３のそれぞれと組み合わせてもよい。 In the fourth embodiment, if the temperature inside the bathroom does not rise to the reference temperature within a predetermined time after starting the operation in the heating mode, it is assumed that an abnormality has occurred in the bathroom 111, and the operator carries it. A confirmation notice is sent to the terminal 6. As a result, when operating in the heating mode, it is possible to detect at an early stage the possibility that the outside air is invading while the window of the bathroom 111, which causes the temperature inside the bathroom to not rise, remains open. If the operator is near the bathroom 111, check the bathroom 111 to eliminate the cause of the temperature inside the bathroom not rising, and if the operator is not near the bathroom 111, use the heating mode from the operation screen 60. You can stop the operation of. The fourth embodiment may be combined with each of the first to third embodiments.
　つぎに、実施の形態１から４による浴室乾燥機２の制御部１０５を実現するハードウェアの構成について説明する。図１５は、実施の形態１から４による制御部を実現するハードウェア構成の一例を模式的に示す図である。制御部１０５は、図１５に示される処理回路２００で実現可能である。 Next, the configuration of the hardware that realizes the control unit 105 of the bathroom dryer 2 according to the first to fourth embodiments will be described. FIG. 15 is a diagram schematically showing an example of a hardware configuration that realizes the control unit according to the first to fourth embodiments. The control unit 105 can be realized by the processing circuit 200 shown in FIG.
　処理回路２００は、プロセッサ２０１、メモリ２０２、入力回路２０３および出力回路２０４を有する。プロセッサ２０１は、ＣＰＵ（Central　Processing　Unit、中央処理装置、処理装置、演算装置、マイクロプロセッサ、マイクロコンピュータ、プロセッサ、ＤＳＰともいう）、システムＬＳＩ（Large　Scale　Integration）などである。メモリ２０２は、ＲＡＭ（Random　Access　Memory）、ＲＯＭ（Read　Only　Memory）、フラッシュメモリ、ＥＰＲＯＭ（Erasable　Programmable　Read　Only　Memory）、ＥＥＰＲＯＭ（登録商標）（Electrically　Erasable　Programmable　Read-Only　Memory）等の、不揮発性または揮発性の半導体メモリ、磁気ディスク、フレキシブルディスク、光ディスク、コンパクトディスク、ミニディスク、ＤＶＤ（Digital　Versatile　Disc）等である。 The processing circuit 200 includes a processor 201, a memory 202, an input circuit 203, and an output circuit 204. The processor 201 is a CPU (Central Processing Unit, central processing unit, processing unit, arithmetic unit, microprocessor, microcomputer, processor, also referred to as DSP), a system LSI (Large Scale Integration), or the like. The memory 202 is a non-volatile or non-volatile memory such as RAM (Random Access Memory), ROM (Read Only Memory), flash memory, EEPROM (Erasable Programmable Read Only Memory), EEPROM (registered trademark) (Electrically Erasable Programmable Read-Only Memory). Volatile semiconductor memory, magnetic disk, flexible disk, optical disk, compact disk, mini disk, DVD (Digital Versatile Disc), etc.
　制御部１０５は、対応するプログラムをメモリ２０２から読み出してプロセッサ２０１が実行することにより実現できる。入力回路２０３は、プロセッサ２０１が処理する情報、メモリ２０２が記憶する情報などを外部から受け取る際に使用される。出力回路２０４は、プロセッサ２０１が生成した情報、メモリ２０２が記憶している情報を外部へ出力する際に使用される。 The control unit 105 can be realized by reading the corresponding program from the memory 202 and executing the processor 201. The input circuit 203 is used when receiving information processed by the processor 201, information stored in the memory 202, and the like from the outside. The output circuit 204 is used to output the information generated by the processor 201 and the information stored in the memory 202 to the outside.
