Description

本発明は、例えば、天井埋込形の室内ユニットを備えた空気調和機に関するものである。   The present invention relates to an air conditioner including, for example, a ceiling-embedded indoor unit.

従来の天井埋込形の室内ユニットとして、空調を行う室内の正確な温度分布を把握するために、例えば赤外線を利用した温度センサーを備えたものがある。その温度センサーが検出した温度分布のデータを基に、吹出口から調和空気の吹出方向の決定と風量の分配の調節を行って、空調エリアに温度差が生じないようにしたり、無駄な空調を排除し、省エネの気流制御などを行っている（例えば、特許文献１参照）。   As a conventional ceiling-embedded indoor unit, there is one provided with a temperature sensor using infrared rays, for example, in order to grasp an accurate temperature distribution in a room for air conditioning. Based on the temperature distribution data detected by the temperature sensor, the direction of the conditioned air is determined from the outlet and the distribution of the air volume is adjusted so that there is no temperature difference in the air-conditioning area, and unnecessary air conditioning is performed. Eliminating energy-saving airflow control is performed (for example, see Patent Document 1).

特開２００３−１９４３８９号公報（第２−１０頁、第２図）JP 2003-194389 (page 2-10, FIG. 2)

従来の天井埋込形の室内ユニットは、１つのファンに対して複数の吹出口を設けている場合が多く、各吹出口の風向板によって風向と風量を分配している。しかし、ファンの回転数はそのままで、風向板で風向を調節しようとすると風向によっては風量が少なくなる場合がある。それにより、室内を目標温度まで近づけるのに多くの時間を要していた。また、風向板の調節で風量が少なくなった場合、ファンの回転数を上げることで解決されるが、ファンの回転音が大きくなったり、更にユーザーに強い気流を当ててしまい、不快感を与えるという課題があった。   Conventional ceiling-embedded indoor units often have a plurality of air outlets for one fan, and the air direction and the air volume are distributed by the air direction plates of each air outlet. However, if the rotational speed of the fan remains the same and the wind direction is adjusted with the wind direction plate, the air volume may decrease depending on the wind direction. As a result, it took a lot of time to bring the room close to the target temperature. In addition, when the airflow is reduced by adjusting the airflow direction plate, it can be solved by increasing the fan speed, but the fan's rotating sound becomes louder or more intense airflow is applied to the user, causing discomfort. There was a problem.

本発明は、前記のような課題を解決するためになされたもので、ファンの回転数を上げることなく、風向と風量の制御を行うことができ、快適性と省エネ性の向上を図ることができる空気調和機を得ることを目的とする。   The present invention has been made to solve the above-described problems, and can control the air direction and the air volume without increasing the rotational speed of the fan, thereby improving comfort and energy saving. The purpose is to obtain an air conditioner that can be used.

本発明に係る空気調和機は、天井面から露出する化粧パネルに設けられた少なくとも１つの吸込口と、化粧パネルに設けられ、床面に対して上下方向に可変する風向板を有する複数の吹出口と、複数の吹出口に対応して設けられた複数の熱交換器と、複数の吹出口に対応して設けられ、吸込口から室内の空気を吸引し熱交換器を介して吹出口から室内に吹き出す複数の送風機とを有する室内ユニットを備え、室内ユニットは、更に、複数の吹出口から互いに反対方向に吹き出される空気の方向に回動して温度分布を検出する少なくとも１つの温度センサーと、温度センサーにより検出された温度分布に温度差のあるエリアが存在するときには、複数の送風機のうち、エリア以外のエリアに空気を送風する送風機の回転数を制御すると共に、複数の吹出口のうち、温度差のあるエリア側に向けられた吹出口の風向板の角度を制御する制御装置とを備え、温度センサーは、赤外線センサーであって、吹出口から吹き出される空気の方向に直交する方向の両端に、先端が半円形状に形成された側板を有している。 An air conditioner according to the present invention includes at least one suction port provided in a decorative panel exposed from a ceiling surface, and a plurality of air blowing plates provided in the decorative panel and having a wind direction plate that is vertically variable with respect to the floor surface. An outlet, a plurality of heat exchangers provided in correspondence with the plurality of outlets, and provided in correspondence with the plurality of outlets, sucking indoor air from the inlet and from the outlet through the heat exchanger An indoor unit having a plurality of blowers to be blown into the room, and the indoor unit further rotates in a direction opposite to each other from the plurality of air outlets to detect a temperature distribution. If, when the area with a temperature difference of the detected temperature distribution by the temperature sensor exists, among the plurality of fans, to control the rotational speed of the blower for blowing air to the outside et rear area, double Of the air outlet, and a control device for controlling the angle of the wind direction plate of the air outlet directed towards the area side with a temperature difference, the temperature sensor is an infrared sensor, the air blown out from the air outlet At both ends in a direction orthogonal to the direction, there are side plates whose tips are formed in a semicircular shape .

本発明によれば、温度センサーにより検出された温度分布に温度差のあるエリアが存在するときには、複数の送風機のうち、前記エリア以外のエリアに空気を送風する送風機の回転数を制御している。このため、送風機の回転音を抑えた状態で、温度差のあるエリアの温度を周囲の温度に近づけることができる。また、複数の吹出口のうち、温度差のあるエリア側に向けられた吹出口の風向板の角度を制御するようにしているので、温度差のあるエリアの温度を周囲の温度に近づける時間が速くなり、快適性と省エネ性を図ることができる。   According to the present invention, when there is an area having a temperature difference in the temperature distribution detected by the temperature sensor, the rotational speed of the blower that blows air to an area other than the area among the plurality of blowers is controlled. . For this reason, the temperature of the area with a temperature difference can be brought close to the ambient temperature in a state where the rotational noise of the blower is suppressed. Moreover, since the angle of the wind direction plate of the air outlet directed to the area side having the temperature difference among the plurality of air outlets is controlled, the time for bringing the temperature of the area having the temperature difference close to the ambient temperature is set. Faster and more comfortable and energy saving.

図１は実施の形態１に係る空気調和機の室内ユニットの外観を示す斜視図、図２は図１の室内ユニットの内部を模式的に示す断面図、図３は図１の温度センサーを拡大して示す斜視図である。
実施の形態１に係る空気調和機は、室内ユニット１と、この室内ユニット１に冷媒配管を介して接続された室外ユニットとを備えている。室内ユニット１は、例えば、長方形形状の化粧パネル２が天井面から露出するように取り付けられる天井埋込形の室内機である。 Embodiment 1 FIG.
1 is a perspective view showing the appearance of an indoor unit of an air conditioner according to Embodiment 1, FIG. 2 is a cross-sectional view schematically showing the interior of the indoor unit of FIG. 1, and FIG. 3 is an enlarged view of the temperature sensor of FIG. It is a perspective view shown.
The air conditioner according to Embodiment 1 includes an indoor unit 1 and an outdoor unit connected to the indoor unit 1 via a refrigerant pipe. The indoor unit 1 is, for example, a ceiling-embedded indoor unit that is attached so that the rectangular decorative panel 2 is exposed from the ceiling surface.

室内ユニット１は、図１に示すように、化粧パネル２の短手方向の両端に設けられた２つの吹出口３、４と、化粧パネル２の吹出口３、４の間に設けられた３つの長方形形状の吸込口５ａ、５ｂ、５ｃと、吹出口３、４の間であって、化粧パネル２の長手方向の両端のうちの片面に設置された温度センサー６とを備えている。   As shown in FIG. 1, the indoor unit 1 includes two air outlets 3 and 4 provided at both ends in the short direction of the decorative panel 2 and 3 provided between the air outlets 3 and 4 of the decorative panel 2. Two rectangular suction ports 5 a, 5 b, 5 c, and a temperature sensor 6 disposed on one side of both ends of the decorative panel 2 in the longitudinal direction between the blowout ports 3, 4 are provided.

温度センサー６の設置は、吹出口３、４から吹き出される調和空気の温度（冷房時は室温より低い温度、暖房時は室温より高い温度）、室内ユニット１自体の温度、吸込口５ａ、５ｂ、５ｃに吸い込まれる室内空気の温度を検出しない位置である。つまり、温度センサー６は、空調時における室内の温度のみを検出することができる位置に設置されている。   The temperature sensor 6 is installed by adjusting the temperature of the conditioned air blown from the air outlets 3 and 4 (temperature lower than room temperature during cooling and temperature higher than room temperature during heating), the temperature of the indoor unit 1 itself, and the inlets 5a and 5b. This is a position where the temperature of the indoor air sucked into 5c is not detected. That is, the temperature sensor 6 is installed at a position where only the indoor temperature during air conditioning can be detected.

吹出口３、４には、床面に対して上下方向に風向を可変する風向板３ａ、４ａがそれぞれ設けられている。この風向板３ａ、４ａは、図２に示すように、それぞれ吹出口３、４の長手方向に延びる軸７、８に取り付けられている。この軸７、８は、図示していないが、回転方向が切り替えられるように、モーターを有する機構部と連動するように構成されている。   The air outlets 3 and 4 are respectively provided with wind direction plates 3a and 4a that change the air direction in the vertical direction with respect to the floor surface. As shown in FIG. 2, the wind direction plates 3a and 4a are attached to shafts 7 and 8 extending in the longitudinal direction of the air outlets 3 and 4, respectively. Although not shown, the shafts 7 and 8 are configured to be interlocked with a mechanism having a motor so that the rotation direction can be switched.

室内ユニット１の内部には、図２に示すように、２組の熱交換器９、１０と、２台の貫流ファン１１、１２（送風機）と、貫流ファン１１と吹出口３との間および貫流ファン１２と吹出口４との間にそれぞれ形成された風路１３と、制御装置２０とが設けられている。熱交換器９は、上部が吸込口５ａ側に傾けられた第１熱交換器９ａと、上部が吸込口５ｂ側に傾けられた第２熱交換器９ｂとで構成されている。もう１組の熱交換器１０は、上部が吸込口５ａ側に傾けられた第１熱交換器１０ａと、上部が吸込口５ｃ側に傾けられた第２熱交換器１０ｂとで構成されている。   In the interior of the indoor unit 1, as shown in FIG. 2, two sets of heat exchangers 9 and 10, two cross-flow fans 11 and 12 (blowers), a cross-flow fan 11 and a blow-out port 3, and An air passage 13 formed between the cross-flow fan 12 and the outlet 4 and a control device 20 are provided. The heat exchanger 9 includes a first heat exchanger 9a whose upper part is inclined toward the suction port 5a and a second heat exchanger 9b whose upper part is inclined toward the suction port 5b. Another set of heat exchangers 10 includes a first heat exchanger 10a whose upper part is inclined toward the inlet 5a and a second heat exchanger 10b whose upper part is inclined toward the inlet 5c. .

貫流ファン１１、１２は、室内ユニット１の長手方向に長い筒形状のファンである。貫流ファン１１は、熱交換器９の第１熱交換器９ａと第２熱交換器９ｂとの間に配置され、貫流ファン１２は、熱交換器１０の第１熱交換器１０ａと第２熱交換器１０ｂとの間に配置されている。貫流ファン１１、１２の運転により、吸込口５ａ、５ｂ、５ｃから室内の空気を吸引し熱交換器９、１０を介して吹出口３、４から室内に吹き出す。熱交換器９、１０は、冷房運転時には蒸発器として作用し、暖房運転時には凝縮器として作用する。   The cross-flow fans 11 and 12 are cylindrical fans that are long in the longitudinal direction of the indoor unit 1. The cross-flow fan 11 is disposed between the first heat exchanger 9 a and the second heat exchanger 9 b of the heat exchanger 9, and the cross-flow fan 12 is the first heat exchanger 10 a and the second heat exchanger 10 of the heat exchanger 10. It arrange | positions between the exchangers 10b. By operating the cross-flow fans 11 and 12, indoor air is sucked from the suction ports 5 a, 5 b and 5 c and blown out from the blowout ports 3 and 4 through the heat exchangers 9 and 10. The heat exchangers 9 and 10 function as an evaporator during the cooling operation, and function as a condenser during the heating operation.

温度センサ−６は、赤外線センサーからなり、図２に示すように、吹出口３、４から互いに反対方向に吹き出される空気（調和空気）の吹出方向Ａ、Ｂに回動するように、化粧パネル２に回動自在（Ｇ方向）に取り付けられている。この温度センサ−６は、図３に示すように、化粧パネル２に設けられた四辺形形状の穴１４から突出しており、吹出口３、４から吹き出される空気の方向に直交する方向、即ち、前述のＧ方向に直交する方向の両端に、先端が半円形状に形成された側板６ａが設けられている。この半円形状の側板６ａは、化粧パネル２の意匠性を損なわないようにするためであり、また、温度センサー６の回動中における室内の温度分布を正確に検出するために設けられている。温度センサー６は、モーターを有する機構部によって、前述したＧ方向に回動し、室内の空間を温度検出範囲Ｈとして検出している。   The temperature sensor-6 is composed of an infrared sensor, and as shown in FIG. 2, makeup is performed so as to rotate in the blowing directions A and B of air (conditioned air) blown in the opposite directions from the blowout ports 3 and 4. It is attached to the panel 2 so as to be rotatable (G direction). As shown in FIG. 3, the temperature sensor 6 protrudes from a quadrangular hole 14 provided in the decorative panel 2, and is a direction orthogonal to the direction of air blown from the blowout ports 3, 4, that is, Side plates 6a having tips formed in a semicircular shape are provided at both ends in the direction perpendicular to the G direction. This semicircular side plate 6a is provided so as not to impair the design of the decorative panel 2, and is provided to accurately detect the temperature distribution in the room while the temperature sensor 6 is rotating. . The temperature sensor 6 is rotated in the above-described G direction by a mechanism having a motor, and detects an indoor space as a temperature detection range H.

制御装置２０は、温度センサー６により検出された温度検出範囲Ｈの温度分布に温度差のあるエリアが存在するときには、複数の貫流ファン１１、１２のうち、前記エリア以外のエリアに空気を送風する貫流ファン１１又は１２の運転停止、あるいは回転数を低下させる制御を行うと共に、複数の吹出口３、４のうち、温度差のあるエリア側に向けられた吹出口３の風向板３ａ又は吹出口４の風向板４ａ、あるいは両方の風向板３ａ、４ａの角度を制御する。なお、制御装置２０による貫流ファン１１、１２の回転数の制御および吹出口３、４の風向板３ａ、４ａの角度の制御については、動作を説明するときに詳述する。   When there is an area with a temperature difference in the temperature distribution of the temperature detection range H detected by the temperature sensor 6, the control device 20 blows air to an area other than the area among the plurality of cross-flow fans 11 and 12. While controlling the operation of the once-through fan 11 or 12 or reducing the rotational speed, the airflow direction plate 3a or the air outlet of the air outlet 3 that is directed to the area side having a temperature difference among the air outlets 3 and 4 The angle of the four wind direction plates 4a or both of the wind direction plates 3a and 4a is controlled. The control of the rotational speed of the cross-flow fans 11 and 12 and the control of the angle of the wind direction plates 3a and 4a of the outlets 3 and 4 by the control device 20 will be described in detail when the operation is described.

前記のように構成された室内ユニット１の動作について説明する。
制御装置２０は、冷房運転あるいは暖房運転を行っているときに、例えば一定時間毎に、温度センサー６を吹出方向Ａ、Ｂに回動するように、温度センサー６の機構部を制御する。この時、温度センサー６は、室内空間の温度検出範囲Ｈの温度分布を検出し、制御装置２０に入力する。 The operation of the indoor unit 1 configured as described above will be described.
When performing the cooling operation or the heating operation, the control device 20 controls the mechanism of the temperature sensor 6 so that the temperature sensor 6 is rotated in the blowing directions A and B at regular intervals, for example. At this time, the temperature sensor 6 detects the temperature distribution in the temperature detection range H of the indoor space and inputs it to the control device 20.

制御装置２０は、温度検出範囲Ｈの温度分布が入力されると、吹出方向Ａ側の温度分布と吹出方向Ｂ側の温度分布とに温度差が存在するか否かを判定する。制御装置２０は、温度分布に第１設定温度（例えば１０ｄｅｇ）以上の温度差のあるエリアが存在するときには、例えば、貫流ファン１１、１２のうち、目標温度に近い温度分布を有するエリア側に空気を送風する貫流ファン１１の運転を停止する。   When the temperature distribution of the temperature detection range H is input, the control device 20 determines whether there is a temperature difference between the temperature distribution on the blowing direction A side and the temperature distribution on the blowing direction B side. When there is an area having a temperature difference equal to or higher than the first set temperature (for example, 10 deg) in the temperature distribution, the control device 20 sets the air to the area side of the cross-flow fans 11 and 12 that has a temperature distribution close to the target temperature, for example. The operation of the cross-flow fan 11 that blows air is stopped.

この時、制御装置２０は、貫流ファン１１側の吹出口３の風向板３ａを、貫流ファン１１を停止させる前の状態のままとする。即ち、吹出口３を風向板３ａで閉じないようにしている。風向板３ａで吹出口３を閉じた場合、その状態を見たユーザーが室内ユニット１が勝手に運転停止したと勘違いする可能性があるため、吹出口３（又は吹出口４）を閉じないようにしている。制御装置２０は、吹出口３側の貫流ファン１１を停止した際に、例えば吹出口３、４のうち、温度分布に第１設定温度以上の温度差のあるエリア側に向けられた吹出口４から、そのエリアに空気が向かうように、吹出口４の風向板４ａの角度を制御する。   At this time, the control device 20 keeps the wind direction plate 3a of the outlet 3 on the side of the cross-flow fan 11 as it was before the cross-flow fan 11 was stopped. That is, the air outlet 3 is not closed by the wind direction plate 3a. When the air outlet 3 is closed with the wind direction plate 3a, the user who sees the state may misunderstand that the indoor unit 1 has been stopped without permission, so do not close the air outlet 3 (or the air outlet 4). I have to. When the cross-flow fan 11 on the outlet 3 side is stopped, the control device 20, for example, out of the outlets 3 and 4, the outlet 4 directed to the area side having a temperature difference equal to or higher than the first set temperature in the temperature distribution. Then, the angle of the wind direction plate 4a of the outlet 4 is controlled so that the air is directed to the area.

制御装置２０は、吹出方向Ａ側の温度分布と吹出方向Ｂ側の温度分布に第１設定温度（１０ｄｅｇ）未満で、その第１設定温度より低い第２設定温度（例えば５ｄｅｇ）以上の温度差のあるエリアが存在するときには、例えば、貫流ファン１１、１２のうち、目標温度に近い温度分布を有するエリア側に空気を送風する貫流ファン１１の回転数をその前の回転数よりも低くする。例えば、２台の貫流ファン１１、１２を１０００ｒｐｍの回転数で運転している場合に、貫流ファン１１の回転数を５００ｒｐｍまで低下させる。   The control device 20 has a temperature difference between the temperature distribution on the blowing direction A side and the temperature distribution on the blowing direction B side that is lower than the first set temperature (10 deg) and lower than the first set temperature (for example, 5 deg). When there is a certain area, for example, the rotational speed of the cross-flow fan 11 that blows air to the area side having a temperature distribution close to the target temperature among the cross-flow fans 11 and 12 is made lower than the previous rotational speed. For example, when the two cross-flow fans 11 and 12 are operated at a rotational speed of 1000 rpm, the rotational speed of the cross-flow fan 11 is reduced to 500 rpm.

制御装置２０は、吹出口３側の貫流ファン１１の回転数を低くした際に、例えば、吹出口３、４のうち、温度分布に第１設定温度（１０ｄｅｇ）未満で、第１設定温度より低い第２設定温度（５ｄｅｇ）以上の温度差のあるエリア側に向けられた吹出口４から、そのエリアに空気が向かうように、吹出口４の風向板４ａの角度を制御する。   When the control device 20 reduces the rotation speed of the cross-flow fan 11 on the outlet 3 side, for example, the temperature distribution of the outlets 3 and 4 is less than the first set temperature (10 deg) and the first set temperature. The angle of the airflow direction plate 4a of the blower outlet 4 is controlled so that the air is directed to the area from the blower outlet 4 directed to the area side having a temperature difference equal to or higher than the low second set temperature (5 deg).

以上のように実施の形態１においては、温度センサー６の両端に半円形形状の側板６ａを設け、その温度センサ−６を吹出方向Ａ、Ｂに回動するようにしているので、化粧パネル２の意匠性を損なうようなことがなく、温度センサー６の回動中における室内の温度分布を正確に検出することができる。   As described above, in the first embodiment, the temperature sensor 6 is provided with the semicircular side plates 6a at both ends, and the temperature sensor-6 is rotated in the blowing directions A and B. The temperature distribution in the room during the rotation of the temperature sensor 6 can be accurately detected without impairing the design.

更に、吹出方向Ａ側の温度分布と吹出方向Ｂ側の温度分布とに第１設定温度（１０ｄｅｇ）以上の温度差があるエリアが存在するときには、目標温度に近い温度分布を有するエリア側に空気を送風する貫流ファン１１又は１２の運転を停止し、また、前述の温度分布に第１設定温度（１０ｄｅｇ）未満で、その第１設定温度より低い第２設定温度（例えば５ｄｅｇ）以上の温度差のあるエリアが存在するときには、目標温度に近い温度分布を有するエリア側に空気を送風する貫流ファン１１又は１２の回転数をその前の回転数よりも低くしている。これにより、貫流ファン１１、１２の回転音を抑えた状態で、室内の温度を目標温度に近づけることができる。   Furthermore, when there is an area where the temperature distribution on the blowing direction A side and the temperature distribution on the blowing direction B side have a temperature difference equal to or greater than the first set temperature (10 deg), air is present on the area side having a temperature distribution close to the target temperature. The operation of the once-through fan 11 or 12 that blows air is stopped, and the temperature difference is less than the first set temperature (10 deg) and lower than the first set temperature (for example, 5 deg) in the above temperature distribution. When there is a certain area, the rotational speed of the once-through fan 11 or 12 that blows air to the area side having a temperature distribution close to the target temperature is set lower than the previous rotational speed. Thereby, the room temperature can be brought close to the target temperature in a state where the rotational noise of the cross-flow fans 11 and 12 is suppressed.

貫流ファン１１又は１２の運転を停止した際、温度差のあるエリア側に向けられた吹出口３、４から吹き出される空気が温度差のあるエリアに向かうように、吹出口３又は４の風向板３ａ、４ａの角度を制御し、また、貫流ファン１１又は１２の回転数を低下させた際、温度差のあるエリア側に向けられた吹出口３又は４から吹き出される空気が温度差のあるエリアに向かうように、吹出口３又は４の風向板３ａ、４ａの角度を制御している。このため、温度差のあるエリアの温度を目標温度に近づける時間が速くなり、快適性と省エネ性を図ることができる。   When the operation of the cross-flow fan 11 or 12 is stopped, the air direction of the air outlet 3 or 4 is such that the air blown out from the air outlets 3 and 4 directed toward the area having the temperature difference is directed to the area having the temperature difference. When the angle of the plates 3a and 4a is controlled and the rotational speed of the cross-flow fan 11 or 12 is reduced, the air blown out from the outlet 3 or 4 directed to the area side where the temperature difference is The angle of the wind direction plates 3a and 4a of the air outlet 3 or 4 is controlled so as to go to a certain area. For this reason, the time taken to bring the temperature of an area with a temperature difference close to the target temperature is increased, and comfort and energy saving can be achieved.
