Description

【０００１】
【発明の属する技術分野】
本発明は、室外の熱源機から室内の床暖房パネルに温水を供給して、室内を暖房する床暖房装置に関する。
【０００２】
【従来の技術】
従来より、図４に示したように、室外に設置された熱源機１００により加熱された温水を、循環路１０１を介して室内の床１０２に設置された床暖房パネル１０３に供給して室内を暖房する床暖房装置が知られている。
【０００３】
かかる床暖房装置においては、暖房を開始するためには、室外の熱源機１００を作動させて温水の加熱と供給を開始する必要がある。また、暖房を停止するためには、室外の熱源機１００の作動を停止して温水の供給を止める必要がある。そこで、使用者が室内から熱源機１００の作動と停止を指示できるようにするため、室内には、熱源機１００の作動を遠隔操作するリモコン１０４が備えられている。
【０００４】
ここで、床暖房装置のリモコン１０４をルームエアコンのリモコンのように無線式とすることも考えられるが、熱源機１００は室外に設置されているため、ルームエアコン等の家電製品で普及している比較的安価な赤外線式の無線リモコンでは無線信号が壁で妨げられ、熱源機１００と交信することができない。
【０００５】
そのため、床暖房装置のリモコン１０４を無線式にするためには、壁を通過できるレベルの電波を出力可能な仕様としなければならないが、この場合にはリモコン１０４のコストが高くなってしまうため、無線式のリモコンを採用することは難しい。そこで、従来の床暖房装置においては、有線式のリモコン１０４が用いられ、室内の壁面に設けられたリモコン１０４と熱源機１００とを壁面を貫通した通信ケーブル１０５で接続するようにしていた。
【０００６】
しかし、このように有線式のリモコン１０４を採用したときには、床暖房装置の作動を指示する際に、使用者はリモコン１０４の設置箇所まで行かなければならないため、無線式のリモコンに比べて使い勝手が悪くならざるを得ない。また、リモコン１０４は使用者の操作性を考慮するとある程度の大きさを確保する必要がある。そのため、リモコン１０５を壁面に設けたときに、リモコン１０５が室内の全体的なデザインに融合せず、室内のデザインの調和に悪影響を与えてしまう場合があった。
【０００７】
【発明が解決しようとする課題】
本発明は、上記背景を鑑みてなされたものであり、屋外に設置された熱源機を無線により遠隔操作するリモコン備えた床暖房装置をコストを抑えて提供することを目的とする。
【０００８】
【課題を解決するための手段】
上記目的を達成するため、本発明は、室外に設置されて熱交換媒体を加熱して供給する熱源機と、該熱源機と該熱交換媒体の循環路により接続されて室内の床に設置され、該熱源機から該循環路を介して供給される熱交換媒体を熱源として室内を暖房する床暖房パネルとを備えた床暖房装置において、室内に設置されて前記熱源機と有線により通信可能に接続された通信中継ユニットと、該通信中継ユニットと無線による通信を行なうリモコンとを備え、該通信中継ユニットは、該リモコンから無線により送信された前記熱源機に対する制御信号を受信したときに、該制御信号を前記熱源機に対して有線により送信し、該通信中継ユニットに、使用者により操作されるスイッチと、該スイッチの操作に応じて、前記リモコンから送信される前記制御信号によらずに、前記熱源機に対して該熱源機の作動又は停止を指示する制御信号を送信する制御信号送信手段とを備えたことを特徴とする。
【０００９】
かかる本発明によれば、前記リモコンと前記通信中継ユニット間の無線通信は室内で実行されるため、比較的安価な赤外線や微弱電波により行なうことができる。そのため、前記リモコンと前記通信中継ユニットを比較的安価に構成することができ、室内のリモコンから室外に設置された前記熱源機の作動を無線により指示することができる床暖房装置を、コストを抑えて実現することができる。さらに、前記通信中継ユニットには、無線信号の送受信部のみを設ければよく、操作スイッチや表示部等は不要であるため、有線式のリモコンよりも大幅に小型化することができる。そのため、前記通信中継ユニットを、室内のデザインの調和を乱さないように目立たない位置に設置することが可能である。
さらに、本発明によれば、前記リモコンの電池切れや故障が生じて前記リモコンを使用することができなくなったときに、前記スイッチを操作することによって、前記熱源機の作動と停止を指示することができる。
【００１０】
また、前記通信中継ユニットに室温を検出する室温センサを備えて該通信中継ユニットを室内の所定の温度検出位置に設け、該通信中継ユニットから前記熱源機に対して該室温センサの温度検出信号を送信し、前記熱源機は、該室温センサの温度検出信号に基づいて室内の温調制御を行なうことを特徴とする。
【００１１】
かかる本発明によれば、有線式のリモコンを室内の壁面に設ける場合のように、使用者が操作し易い位置に前記通信中継ユニットを設ける必要がない。そのため、前記室温センサを備えた前記通信中継ユニットを室温を検出したい箇所（例えば床面に近い位置等）に設けて、室温を検出することができる。
【００１４】
【発明の実施の形態】
本発明の実施の形態の一例について、図１〜図３を参照して説明する。図１は本発明の床暖房装置の全体構成図、図２は図１に示した熱源機を遠隔操作するためのリモコン及び通信中継ユニットの外観図、図３はリモコンと通信中継ユニットと熱源機の制御ブロック図である。
【００１５】
図１を参照して、本発明の床暖房装置は、室外に設けられた熱源機１と、室内の床３に設置されて循環路２により熱源機１と接続された床暖房パネル４と、熱源機１に対する制御信号を無線で送信するリモコン５と、熱源機１と通信ケーブル６により通信可能に接続され、リモコン５から無線により送信される制御信号を受信して該制御信号を通信ケーブル６を介して熱源機１に送信する通信中継ユニット７とからなり、熱源機１から循環路２を介して床暖房パネル４に供給される温水（本発明の熱交換媒体に相当する）からの放熱により、室内が暖房される。
【００１６】
図２（ａ）を参照して、リモコン５には、床暖房運転の開始と停止を指示する運転スイッチ１０、所定時刻になったときに床暖房装置の作動を開始又は停止するタイマ運転の入／切を設定するタイマスイッチ１１、暖房温度／時刻／タイマ時間を設定するための設定モードを切替える設定モード切替スイッチ１２、及び暖房温度／時刻／タイマ時間を変更するＵＰ／ＤＯＷＮスイッチ１３が設けられた操作部１４と、暖房温度や時刻等が表示される表示部１５と、赤外線の無線信号を出力する赤外線発光部１６とが備えられている。
【００１７】
また、図２（ｂ）を参照して、通信中継ユニット７には、リモコン５から送信される赤外線の無線信号を入力する赤外線受光部２０、床暖房運転の実行／停止に応じて点灯／消灯する運転ランプ２１、床暖房運転の実行／停止を指示する応急スイッチ２２（本発明のスイッチに相当する）、及び室温を検出するサーミスタ２３（本発明の室温センサに相当する）が備えられている。
【００１８】
次に、図３を参照して、床暖房装置の作動について説明する。床暖房装置の作動は使用者によるリモコン５又は通信中継ユニット７の操作に応じて制御される。
【００１９】
リモコン５は、マイコン等により構成されたリモコンコントローラ３０により全体の作動が制御され、リモコンコントローラ３０は、スイッチ部１４から入力される各スイッチのＯＮ／ＯＦＦ信号に応じて、床暖房運転の開始や停止、暖房温度等を指示する制御信号をリモコン通信部３２に出力する。リモコン通信部３２は、リモコンコントローラ３０からの制御信号を入力すると、該制御信号を赤外線発光部１６により赤外線の無線信号化して、通信中継ユニット７に対して送信する。また、リモコンコントローラ３０は、スイッチ部１４により設定された暖房温度やタイマ設定時間等を表示部１５に表示する。
【００２０】
通信中継ユニット７は、マイコン等により構成された通信中継ユニットコントローラ４０により全体の作動が制御される。そして、通信中継ユニット通信部４１は、リモコン５から無線により送信された制御信号を赤外線受光部２０により電気信号化して受信すると、該制御信号を通信ケーブル６を介して熱源機１に送信する。これにより、リモコン５から無線で送信された制御信号が、通信中継ユニット７を介して有線により熱源機１に伝達される。
【００２１】
この場合、通信中継ユニット７は、リモコン５から送信される赤外線の無線信号を受信する機能と、受信した該無線信号を電気信号に変換して熱源機１に送信する機能のみを備えればよいので小型化することができ、室内の壁面等に室内のデザインの調和を乱さないように設けることができる。
【００２２】
また、リモコン５は比較的安価な赤外線発光部１６を用いて構成され、通信中継ユニット７も比較的安価な赤外線受光部２０を用いて構成されるため、リモコン側に壁を介して通信可能なレベルの電波を出力する機能を備えて室内のリモコンから室外の熱源機１を直接無線で制御する場合に比べて、室内のリモコンから無線により室外の熱源機１の作動を制御する床暖房装置をコストを抑えて実現することができる。
【００２３】
また、通信中継ユニットコントローラ４０には、応急スイッチ２２のＯＮ／ＯＦＦ信号とサーミスタ２３の温度検出信号が入力され、通信中継ユニットコントローラ４０は、応急スイッチ２２が操作されたことを示す応急操作信号とサーミスタ２３の温度検出信号とを通信中継ユニット通信部４１を介して熱源機１に送信する。
【００２４】
この場合、応急スイッチ２２が操作されるのは、リモコン５の電池切れや故障が生じたときのみであり、通常は応急スイッチ２２が操作されることはない。そのため、通信中継ユニット７を設置する際に使用者の操作性を考慮する必要性は低く、例えば床に近い壁面等の室温の検出に適した所定位置に通信中継ユニット７を設置することができる。
【００２５】
次に、熱源機１は、マイコン等により構成された熱源機コントローラ５０により全体の作動が制御され、熱源機コントローラ５０は、熱源機通信部５１を介して、リモコン５又は通信中継ユニット７から送信される制御信号と、通信中継ユニット７から送信されるサーミスタ２３の温度検出信号とを入力する。
【００２６】
そして、熱源機コントローラ５０は、リモコン５から通信中継ユニット７を介して受信した制御信号に応じて、床暖房パネル４への温水の供給／停止を制御する。すなわち、熱源機コントローラ５０は、リモコン５から暖房運転の開始を指示する制御信号を受信したときは、バーナ５２に点火して循環路内の温水の加熱を介し、開閉弁５３を開弁して循環ポンプ５４を作動させることによって、床暖房パネル４への温水の供給を開始する。これにより、床暖房パネル４内を循環する温水からの放熱により室内を暖房する床暖房運転が開始される。
【００２７】
一方、リモコン５から暖房運転の停止を指示する制御信号を受信したときには、熱源機コントローラ５０は、バーナ５２を消火し、循環ポンプ５４を停止し、開閉弁５３を閉弁する。これにより、熱源機１から床暖房パネル４への温水の供給が停止されて、床暖房運転が終了する。
【００２８】
また、熱源機コントローラ５０は、通信中継ユニット７から送信されるサーミスタ２３の温度検出信号から把握される室温が、リモコン５から送信された制御信号に応じて設定された暖房温度と一致するように、開閉弁５３の開弁／閉弁を切替えて熱源機１から床暖房パネル４に供給される温水の時間あたりの供給量を可変する温調制御を行なう。
【００２９】
さらに、熱源機コントローラ５０は、通信中継ユニット７から前記応急操作信号を受信すると、床暖房運転の実行中であったときは床暖房運転を停止し、床暖房運転の停止中であったときには床暖房運転を開始する。これにより、リモコン５の電池切れや故障により、リモコン５により熱源機１を操作できなくなった場合であっても、使用者は、通信中継ユニット７に備えられた応急スイッチ２２を操作することによって、床暖房運転の開始と停止を指示することができる。
【００３０】
なお、本実施の形態においては、通信中継ユニット７に応急スイッチ２２とサーミスタ２３を設けたが、これらを設けない場合、及び応急スイッチ２２とサーミスタ２３のうちのいずれか一方のみを設けた場合であっても本発明の効果を得ることができる。
【００３１】
また、本実施の形態においては、リモコン５と通信中継ユニット７間の無線通信を赤外線により行なったが、微弱電波により行なってもよい。

BACKGROUND OF THE INVENTION
The present invention relates to a floor heating apparatus that heats a room by supplying hot water from an outdoor heat source unit to an indoor floor heating panel.
[0002]
[Prior art]
Conventionally, as shown in FIG. 4, hot water heated by a heat source device 100 installed outdoors is supplied to a floor heating panel 103 installed on a floor 102 in the room via a circulation path 101, A floor heating apparatus for heating is known.
[0003]
In such a floor heating apparatus, in order to start heating, it is necessary to start the heating and supply of warm water by operating the outdoor heat source unit 100. In order to stop heating, it is necessary to stop the operation of the outdoor heat source unit 100 and stop the supply of hot water. In order to allow the user to instruct the operation and stop of the heat source apparatus 100 from the room, a remote controller 104 for remotely operating the operation of the heat source apparatus 100 is provided in the room.
[0004]
Here, it is conceivable that the remote controller 104 of the floor heating apparatus is wireless, like the remote controller of the room air conditioner. However, since the heat source unit 100 is installed outdoors, it is widely used in home appliances such as room air conditioners. With a relatively inexpensive infrared wireless remote controller, the wireless signal is blocked by the wall and cannot communicate with the heat source device 100.
[0005]
Therefore, in order to make the remote control 104 of the floor heating device wireless, it is necessary to make it a specification that can output radio waves at a level that can pass through the wall, but in this case, the cost of the remote control 104 becomes high, It is difficult to adopt a wireless remote control. Therefore, in the conventional floor heating apparatus, a wired remote controller 104 is used, and the remote controller 104 provided on the indoor wall surface and the heat source unit 100 are connected by a communication cable 105 penetrating the wall surface.
[0006]
However, when the wired remote controller 104 is used in this way, the user has to go to the place where the remote controller 104 is installed when instructing the operation of the floor heating device, which is more convenient than the wireless remote controller. It must be bad. The remote controller 104 needs to secure a certain size in consideration of user operability. For this reason, when the remote controller 105 is provided on the wall surface, the remote controller 105 may not be integrated with the overall indoor design, which may adversely affect the harmony of the indoor design.
[0007]
[Problems to be solved by the invention]
This invention is made | formed in view of the said background, and it aims at providing the floor heating apparatus provided with the remote control which carries out remote operation of the heat-source equipment installed outdoors by radio | wireless at low cost.
[0008]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention is installed on a floor in a room connected to a heat source unit that is installed outside and heats and supplies a heat exchange medium, and the heat source unit and a circulation path of the heat exchange medium. , A floor heating apparatus comprising a floor heating panel for heating a room using a heat exchange medium supplied from the heat source unit via the circulation path as a heat source, and is installed indoors and can communicate with the heat source unit by wire A communication relay unit connected to the communication relay unit, and a remote controller that performs wireless communication with the communication relay unit, the communication relay unit receiving the control signal for the heat source device transmitted wirelessly from the remote controller; send a wired control signal to the heat source unit, to the communication relay units, a switch operated by the user, in response to the operation of the switch, prior to being transmitted from the remote controller Regardless of the control signal, characterized in that a control signal transmitting means for transmitting a control signal for instructing the operation or stop of the heat source unit to the heat source unit.
[0009]
According to the present invention, since the wireless communication between the remote controller and the communication relay unit is performed indoors, it can be performed with relatively inexpensive infrared rays or weak radio waves. Therefore, the floor heating device that can configure the remote controller and the communication relay unit relatively inexpensively and can wirelessly instruct the operation of the heat source unit installed outside the room from the indoor remote controller can be reduced in cost. Can be realized. Further, the communication relay unit only needs to be provided with a radio signal transmission / reception unit, and does not require an operation switch, a display unit, or the like, and thus can be significantly reduced in size compared to a wired remote controller. Therefore, it is possible to install the communication relay unit at an inconspicuous position so as not to disturb the harmony of the indoor design.
Furthermore, according to the present invention, when the remote control becomes out of battery or has become defective and the remote control cannot be used, the operation of the heat source unit is instructed by operating the switch. Can do.
[0010]
The communication relay unit includes a room temperature sensor for detecting a room temperature, the communication relay unit is provided at a predetermined temperature detection position in the room, and a temperature detection signal of the room temperature sensor is transmitted from the communication relay unit to the heat source unit. And the heat source unit performs indoor temperature control based on a temperature detection signal of the room temperature sensor.
[0011]
According to the present invention, there is no need to provide the communication relay unit at a position where the user can easily operate, as in the case where the wired remote controller is provided on the wall surface of the room. Therefore, it is possible to detect the room temperature by providing the communication relay unit including the room temperature sensor at a location where the room temperature is desired to be detected (for example, a position close to the floor).
[0014]
DETAILED DESCRIPTION OF THE INVENTION
An example of an embodiment of the present invention will be described with reference to FIGS. 1 is an overall configuration diagram of the floor heating apparatus of the present invention, FIG. 2 is an external view of a remote controller and a communication relay unit for remotely operating the heat source apparatus shown in FIG. 1, and FIG. 3 is a remote controller, a communication relay unit, and a heat source apparatus. It is a control block diagram of.
[0015]
Referring to FIG. 1, a floor heating apparatus according to the present invention includes a heat source unit 1 provided outdoors, a floor heating panel 4 installed on a floor 3 in the room and connected to the heat source unit 1 by a circulation path 2, A remote controller 5 that wirelessly transmits a control signal for the heat source unit 1 and a heat source unit 1 and a communication cable 6 that are communicably connected to each other, receive a control signal transmitted from the remote controller 5 by radio, and transmit the control signal to the communication cable 6. Heat from the hot water (corresponding to the heat exchange medium of the present invention) supplied from the heat source device 1 to the floor heating panel 4 via the circulation path 2. As a result, the room is heated.
[0016]
Referring to FIG. 2A, the remote controller 5 includes an operation switch 10 for instructing start and stop of the floor heating operation, and a timer operation for starting or stopping the operation of the floor heating device when a predetermined time comes. Timer switch 11 for setting / off, setting mode switch 12 for switching the setting mode for setting the heating temperature / time / timer time, and UP / DOWN switch 13 for changing the heating temperature / time / timer time. The operation unit 14, the display unit 15 for displaying the heating temperature, the time, and the like, and the infrared light emitting unit 16 for outputting an infrared radio signal are provided.
[0017]
Further, referring to FIG. 2B, the communication relay unit 7 is turned on / off according to the infrared light receiving unit 20 for inputting the infrared radio signal transmitted from the remote controller 5, according to the execution / stop of the floor heating operation. Operating lamp 21, an emergency switch 22 (corresponding to the switch of the present invention) for instructing execution / stop of the floor heating operation, and a thermistor 23 (corresponding to the room temperature sensor of the present invention) for detecting the room temperature. .
[0018]
Next, the operation of the floor heating apparatus will be described with reference to FIG. The operation of the floor heating device is controlled according to the operation of the remote controller 5 or the communication relay unit 7 by the user.
[0019]
The entire operation of the remote controller 5 is controlled by a remote controller 30 configured by a microcomputer or the like. The remote controller 30 starts the floor heating operation according to the ON / OFF signal of each switch input from the switch unit 14. A control signal instructing stop, heating temperature, etc. is output to the remote control communication unit 32. When receiving a control signal from the remote controller 30, the remote control communication unit 32 converts the control signal into an infrared radio signal by the infrared light emitting unit 16 and transmits it to the communication relay unit 7. In addition, the remote controller 30 displays the heating temperature, the timer set time, and the like set by the switch unit 14 on the display unit 15.
[0020]
The entire operation of the communication relay unit 7 is controlled by a communication relay unit controller 40 configured by a microcomputer or the like. And the communication relay unit communication part 41 will transmit this control signal to the heat-source equipment 1 via the communication cable 6, if the infrared rays light-receiving part 20 converts into an electrical signal and receives the control signal transmitted from the remote control 5 wirelessly. As a result, the control signal transmitted wirelessly from the remote controller 5 is transmitted to the heat source device 1 by wire via the communication relay unit 7.
[0021]
In this case, the communication relay unit 7 only needs to have a function of receiving an infrared radio signal transmitted from the remote controller 5 and a function of converting the received radio signal into an electric signal and transmitting it to the heat source unit 1. Therefore, it can be reduced in size and can be provided on the wall surface of the room so as not to disturb the harmony of the room design.
[0022]
Further, since the remote controller 5 is configured using a relatively inexpensive infrared light emitting unit 16, and the communication relay unit 7 is also configured using a relatively inexpensive infrared light receiving unit 20, communication is possible via a wall on the remote control side. Compared to the case where the outdoor heat source unit 1 is directly wirelessly controlled from the indoor remote controller with a function of outputting a level of radio waves, the floor heating device that controls the operation of the outdoor heat source unit 1 wirelessly from the indoor remote controller is provided. This can be realized at a reduced cost.
[0023]
The communication relay unit controller 40 receives the ON / OFF signal of the emergency switch 22 and the temperature detection signal of the thermistor 23, and the communication relay unit controller 40 receives an emergency operation signal indicating that the emergency switch 22 has been operated. The temperature detection signal of the thermistor 23 is transmitted to the heat source unit 1 via the communication relay unit communication unit 41.
[0024]
In this case, the emergency switch 22 is operated only when the battery of the remote controller 5 is exhausted or malfunctioned, and the emergency switch 22 is not normally operated. Therefore, it is not necessary to consider the user's operability when installing the communication relay unit 7. For example, the communication relay unit 7 can be installed at a predetermined position suitable for detecting room temperature such as a wall surface close to the floor. .
[0025]
Next, the entire operation of the heat source unit 1 is controlled by a heat source unit controller 50 configured by a microcomputer or the like. The heat source unit controller 50 transmits from the remote controller 5 or the communication relay unit 7 via the heat source unit communication unit 51. The control signal to be transmitted and the temperature detection signal of the thermistor 23 transmitted from the communication relay unit 7 are input.
[0026]
Then, the heat source device controller 50 controls supply / stop of hot water to the floor heating panel 4 in accordance with a control signal received from the remote controller 5 via the communication relay unit 7. That is, when the heat source controller 50 receives a control signal instructing the start of the heating operation from the remote controller 5, the heat source controller 50 ignites the burner 52 and opens the on-off valve 53 via heating of the hot water in the circulation path. By operating the circulation pump 54, supply of hot water to the floor heating panel 4 is started. Thereby, the floor heating operation which heats the room by the heat radiation from the hot water circulating in the floor heating panel 4 is started.
[0027]
On the other hand, when receiving a control signal instructing to stop the heating operation from the remote controller 5, the heat source controller 50 extinguishes the burner 52, stops the circulation pump 54, and closes the on-off valve 53. Thereby, supply of the warm water from the heat source unit 1 to the floor heating panel 4 is stopped, and the floor heating operation ends.
[0028]
In addition, the heat source controller 50 is configured such that the room temperature obtained from the temperature detection signal of the thermistor 23 transmitted from the communication relay unit 7 matches the heating temperature set according to the control signal transmitted from the remote controller 5. Then, temperature control is performed to change the amount of hot water supplied from the heat source unit 1 to the floor heating panel 4 per hour by switching between opening and closing of the on-off valve 53.
[0029]
Further, when receiving the emergency operation signal from the communication relay unit 7, the heat source controller 50 stops the floor heating operation when the floor heating operation is being performed, and stops when the floor heating operation is stopped. Start heating operation. Thereby, even when the heat source unit 1 cannot be operated by the remote controller 5 due to a battery exhaustion or failure of the remote controller 5, the user can operate the emergency switch 22 provided in the communication relay unit 7 to The start and stop of the floor heating operation can be instructed.
[0030]
In the present embodiment, the emergency switch 22 and the thermistor 23 are provided in the communication relay unit 7. However, in the case where these are not provided, and in the case where only one of the emergency switch 22 and the thermistor 23 is provided. Even if it exists, the effect of this invention can be acquired.
[0031]
In the present embodiment, the wireless communication between the remote controller 5 and the communication relay unit 7 is performed using infrared rays, but may be performed using weak radio waves.
