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。この実施の形態によって本発明が限定されるものではない。 Embodiments of the present invention will be described below with reference to the drawings. In addition. The present invention is not limited to this embodiment.
(実施の形態1)
図1は、本発明の第1の実施の形態における給湯装置の構成を示す図である。
(Embodiment 1)
FIG. 1 is a diagram showing the configuration of a water heater according to a first embodiment of the present invention.
図1において、貯湯槽1と、この貯湯槽1の水を加熱する貯湯槽水加熱手段としてのヒートポンプ2と、貯湯槽1の湯と浴槽3の湯を熱交換して風呂の追い焚きをおこなう浴槽水加熱手段としての熱交換器4と、第1の循環ポンプ5と、第2の循環ポンプ6と、浴槽水温度を測定するサーミスタ7と、浴室リモコン8に設けられ、浴室内の在室者の有無を検出する人体検出手段9と、この人体検出手段9からの出力により、浴室11内の人の存在を検知した場合に、その旨を報知する報知部14が設けられている台所リモコン13と、を備えている。 In FIG. 1, a hot water storage tank 1, a heat pump 2 serving as a hot water tank water heating means for heating the water in the hot water storage tank 1, and heat exchange between hot water in the hot water storage tank 1 and hot water in a bathtub 3 to reheat the bath. A heat exchanger 4 as a bathtub water heating means, a first circulation pump 5, a second circulation pump 6, a thermistor 7 for measuring the bathtub water temperature, and a bathroom remote control 8 are provided, and are installed in the bathroom. A kitchen remote controller is provided with a human body detection means 9 for detecting the presence or absence of a person, and a notification section 14 for notifying the presence of a person in the bathroom 11 when the presence of a person is detected by the output from the human body detection means 9. It is equipped with 13.
なお、人体検出手段9には、例えば、赤外線センサが用いられている。 Note that the human body detection means 9 uses, for example, an infrared sensor.
そして、人体検出手段9が、浴室11内の人の存在を検知した場合に、人体検出手段9から出力を受信し、そして台所リモコン13に出力することで、その旨を台所リモコン13の報知部14に報知する浴室使用表示機能や、第1の循環ポンプ5や第2の循環ポンプ6の運転動作を制御して、浴槽3内の湯水を保温する風呂保温運転機能を実行する制御手段10を備えている。 When the human body detection means 9 detects the presence of a person in the bathroom 11, the human body detection means 9 receives an output from the human body detection means 9 and outputs it to the kitchen remote control 13, thereby notifying the notification section of the kitchen remote control 13. The control means 10 executes a bathroom use display function that notifies the bathtub 14, and a bath warming operation function that controls the operation of the first circulation pump 5 and the second circulation pump 6 to keep hot water in the bathtub 3 warm. We are prepared.
図2(a)は、浴室リモコン8正面図、図2(b)は、台所リモコン13の正面図を示している。 2(a) shows a front view of the bathroom remote controller 8, and FIG. 2(b) shows a front view of the kitchen remote controller 13.
図2(a)に示すように、浴室リモコン8の正面には、赤外線センサである人体検出手段9が設けられている。 As shown in FIG. 2(a), a human body detection means 9, which is an infrared sensor, is provided on the front of the bathroom remote control 8.
また、図2(b)に示すように、台所リモコン13には、人体検出手段9が、浴室11内の人の存在を検知した場合に、浴室11内に人が存在していることを、人間を示す絵文字等で、台所リモコン13に表示させて報知する報知部14が設けられている。 Further, as shown in FIG. 2(b), when the human body detection means 9 detects the presence of a person in the bathroom 11, the kitchen remote control 13 can detect the presence of a person in the bathroom 11. A notification section 14 is provided to display and notify on the kitchen remote control 13 a pictogram representing a human being or the like.
図3は、浴室11に設置された浴室リモコン8に設けられた人体検出手段9の視野角を示した図である。 FIG. 3 is a diagram showing the viewing angle of the human body detection means 9 provided on the bathroom remote control 8 installed in the bathroom 11.
図3(a)は浴室11の横断面図、図3(b)は図3(a)のA-A断面図で、浴室リモコン8は、浴槽3の少し上の壁面に設置されている。人体検出手段9の視野角は、左右方向には同角度としている。 3(a) is a cross-sectional view of the bathroom 11, and FIG. 3(b) is a sectional view taken along the line AA in FIG. 3(a), in which the bathroom remote control 8 is installed on the wall slightly above the bathtub 3. The viewing angle of the human body detection means 9 is set to be the same angle in the left and right directions.
ここで、浴室リモコン8の取り付け位置として、平面方向は特定できないが、高さ方向については浴槽3内から、あるいは洗い場で座った状態での操作を可能にするため、ほぼ一定している。 Here, the installation position of the bathroom remote controller 8 cannot be specified in the plane direction, but the height direction is almost constant so that it can be operated from inside the bathtub 3 or while sitting in the washing area.
このため、人体検出手段9の視野角について、左右方向は同角度とせざるを得ず、一方、高さ方向の取り付け位置は低くほぼ一定であるので、下方向の視野角は小さくてよい(∠α>∠β)。 For this reason, the viewing angle of the human body detection means 9 must be the same in the left and right directions, while the mounting position in the height direction is low and almost constant, so the viewing angle in the downward direction may be small (∠ α>∠β).
したがって上方向の視野角を比較的大きくとっても全体としての視野角は小さくでき、その分、感度を上げることができる。 Therefore, even if the upward viewing angle is made relatively large, the overall viewing angle can be made small, and the sensitivity can be increased accordingly.
また、下側の視野角を大きくとると、浴槽3に蓋をされていない場合に浴室リモコン8の設置位置によっては、浴槽3に張られた湯の表面を視野に捉え、その揺れを感知することがある。下方向の視野角を小さくとっておけば、この誤検知を防ぐことができる。12は人である。 Furthermore, if the viewing angle on the lower side is wide, if the bathtub 3 is not covered, depending on the installation position of the bathroom remote control 8, the surface of the hot water in the bathtub 3 can be seen in the field of view and its shaking can be sensed. Sometimes. This false detection can be prevented by keeping the downward viewing angle small. 12 is a person.
以上のように構成された給湯装置について、以下その動作、作用を説明する。 The operation and effect of the water heater configured as above will be explained below.
基本的な機能としては、ヒートポンプ2により加熱された湯が、貯湯槽1に貯えられており、この湯を給湯および浴槽水の加熱に利用する。 The basic function is that hot water heated by a heat pump 2 is stored in a hot water storage tank 1, and this hot water is used for hot water supply and heating of bathtub water.
浴槽水の加熱は、貯湯槽1に貯えられた高温の湯を、第1の循環ポンプ5を用いて、熱交換器4の1次側流路に供給するとともに、第2の循環ポンプ6により、浴槽水を熱交換器4の2次側流路に循環させることによって行われる。 To heat the bathtub water, high-temperature hot water stored in the hot water storage tank 1 is supplied to the primary side flow path of the heat exchanger 4 using the first circulation pump 5 and heated by the second circulation pump 6. This is done by circulating bath water through the secondary flow path of the heat exchanger 4.
人体検出手段9の出力に基づいて、浴室11内の人の存在を検知した場合に、その旨を台所リモコンに報知する浴室使用表示機能について、図4を用いて説明する。 A bathroom use display function that notifies the kitchen remote control when the presence of a person in the bathroom 11 is detected based on the output of the human body detection means 9 will be described with reference to FIG.
まず、浴槽3内の湯水を保温する風呂保温運転機能について説明すると、図2(a)のふろ自動スイッチを使用者がONすると、制御手段10は、第2の循環ポンプ6を起動させて、サーミスタ7により浴槽3内の水温を検出し、これが設定値未満の場合、第1の循環ポンプ5を起動させて、熱交換器4の1次側流路に、貯湯槽1の高温の湯を循環させ、浴槽水を加熱する。 First, to explain the bath warming operation function that keeps hot water in the bathtub 3 warm, when the user turns on the bath automatic switch shown in FIG. 2(a), the control means 10 starts the second circulation pump 6, The thermistor 7 detects the water temperature in the bathtub 3, and if it is less than the set value, the first circulation pump 5 is activated to supply high-temperature hot water from the hot water tank 1 to the primary flow path of the heat exchanger 4. Circulate and heat the bath water.
そして、浴槽水の温度が設定温度に達すれば、第1の循環ポンプ5、および、第2の循環ポンプ6を停止させ、浴槽水の加熱運転を終了する。 When the temperature of the bathtub water reaches the set temperature, the first circulation pump 5 and the second circulation pump 6 are stopped, and the heating operation of the bathtub water is ended.
すなわち、制御手段10が、第2の循環ポンプ6を起動させて、サーミスタ7により浴槽3内の水温の検出を所定時間毎に行い、水温が設定値未満の場合、第1の循環ポンプ5を起動させて、熱交換器4の1次側流路に、貯湯槽1の高温の湯を循環させ、浴槽水を設定温度まで加熱する動作を繰り返すのが、風呂保温運転機能である。 That is, the control means 10 starts the second circulation pump 6, detects the water temperature in the bathtub 3 by the thermistor 7 at predetermined time intervals, and when the water temperature is less than the set value, starts the first circulation pump 5. The bath warming operation function is activated and repeats the operation of circulating high temperature hot water from the hot water storage tank 1 through the primary flow path of the heat exchanger 4 and heating the bath water to a set temperature.
ここで、制御手段10は、図4に示すように、水位センサ(図示せず)にて検知し、浴槽3にお湯がない場合(浴槽3に栓がされていない等)には、浴室使用表示機能を開始させてから、第1所定時間T1(例えば、15秒)以内は、人体検出手段9が、浴室11への人の入室を検知しても、その旨を台所リモコン13の報知部14に報知しないようにしてある時間帯を設けている。 Here, as shown in FIG. 4, the control means 10 detects with a water level sensor (not shown), and if there is no hot water in the bathtub 3 (for example, the bathtub 3 is not plugged), Within the first predetermined time T1 (for example, 15 seconds) after starting the display function, even if the human body detection means 9 detects that a person enters the bathroom 11, the notification section of the kitchen remote control 13 will not notify you of this fact. There is a certain time period in which notifications are not made on 14th.
ただし、制御手段10は、風呂保温運転機能の実行中の場合には、人体検出手段9が、浴室11への人の入室を検知してから、第1所定時間より短い第2所定時間(例えば、0~2秒)以内に、その旨を台所リモコン13の報知部14に報知する。 However, when the bath warming operation function is being executed, the control means 10 detects that the human body detection means 9 detects the entry of a person into the bathroom 11 for a second predetermined time shorter than the first predetermined time (e.g. , 0 to 2 seconds), the notification section 14 of the kitchen remote control 13 is notified of this fact.
また、水位センサ(図示せず)にて検知し、浴槽3にお湯がない場合(浴槽3に栓がされていない等)に、浴室使用表示機能を開始させてから第1所定時間T1(例えば、15秒)経過後の時間帯であるT2においては、人体検出手段9が、浴室11への人の入室を検知してから、第1所定時間より短い第2所定時間(例えば、0~2秒)以内に、その旨を台所リモコン13の報知部14に報知するようにしてある。 In addition, if the water level sensor (not shown) detects that there is no hot water in the bathtub 3 (for example, the bathtub 3 is not plugged), the bathroom use display function is started for a first predetermined period of time T1 (for example, , 15 seconds), the human body detection means 9 detects the entry of a person into the bathroom 11 and then waits for a second predetermined time (for example, 0 to 2 This notification is sent to the notification section 14 of the kitchen remote control 13 within a few seconds.
なお、浴室使用表示機能の開始および停止は、使用者が、制御手段10にて指示することで制御できる。 The start and stop of the bathroom usage display function can be controlled by the user using the control means 10.
以上により、本発明の第1の実施の形態によれば、浴室11の扉が開いていて、人体検出手段9の前を人が横切るだけで、人体検出手段9が反応してしまうということや、また、浴槽3に栓をしに行く為に、浴室11内に短時間入室しただけで、人体検出手段9が反応してしまうということ、すなわち、浴室11内に短時間入室しただけの場合でも、人体検出手段9が反応して、台所リモコン13の報知部14に報知してしまうということを防止でき、浴室11への人の入室の検知精度を向上させた給湯装置を提供できる。 As described above, according to the first embodiment of the present invention, if the door of the bathroom 11 is open and a person crosses in front of the human body detection means 9, the human body detection means 9 will react. In addition, even if the person enters the bathroom 11 for a short time to plug the bathtub 3, the human body detection means 9 will react, that is, if the person only enters the bathroom 11 for a short time. However, it is possible to prevent the human body detection means 9 from reacting and notifying the notification section 14 of the kitchen remote control 13, and it is possible to provide a water heater with improved accuracy in detecting the entry of a person into the bathroom 11.
これに加え、入浴を目的とした浴室11に入室した場合には、台所リモコン13の報知部14に、その旨を適格に報知できるため、浴室11への人の入室の検知精度を向上させた給湯装置を提供できる。 In addition, when a person enters the bathroom 11 for the purpose of taking a bath, the notification section 14 of the kitchen remote controller 13 can appropriately notify the user of this fact, which improves the accuracy of detecting the entry of a person into the bathroom 11. We can provide hot water equipment.
以上のように、本発明にかかる給湯装置は、浴室への人の入室の検知精度が良いので、電気、ガスを熱源とした浴室への人の入室を検知する機能を備えた給湯装置に適用できる。 As described above, the water heater according to the present invention has good accuracy in detecting when a person enters a bathroom, so it can be applied to a water heater that uses electricity or gas as a heat source and has the function of detecting when a person enters a bathroom. can.
