Description

本発明は、一般家庭で使用する空気調和機に関するものである。   The present invention relates to an air conditioner used in ordinary households.

従来より、複数の暖房機間で制御データを双方向通信で供給することで、それぞれの暖房機の特性に応じて運転をおこなうことで経済性や快適性を向上するものが有った。（例えば、特許文献１参照）
また、ファンヒータに併用運転モードを備え、空気調和機とファンヒータが同じ室内で一緒に使用するときには、ファンヒータを熱量が不足する運転開始時のみに使用し、ファンヒータの設定温度到達後にはファンヒータを自動的に停止することで、双方向通信を使用せずにそれぞれの暖房機の特性を利用して快適性を向上するものであった。（例えば、特許文献２参照） 2. Description of the Related Art Conventionally, there has been a configuration in which control data is supplied between a plurality of heaters by two-way communication, and operation is performed in accordance with the characteristics of each heater, thereby improving economy and comfort. (For example, see Patent Document 1)
In addition, the fan heater has a combined operation mode, and when the air conditioner and the fan heater are used together in the same room, the fan heater is used only at the start of operation when the amount of heat is insufficient, and after the set temperature of the fan heater is reached. By automatically stopping the fan heater, the comfort is improved by utilizing the characteristics of each heater without using bidirectional communication. (For example, see Patent Document 2)

特開２００４−２５７６５６号公報JP 2004-257656 A 特許６２５９７８５号公報Japanese Patent No. 6259785

しかしながら、特許文献１の暖房機に使用される双方向通信を行うための装置は高価であり、一般家庭で使用するにはそぐわない。また、ファンヒータのように移動して使用するほとんどの暖房機は通信機能を備えていない。
また、特許文献２に示されているファンヒータは、室温がファンヒータの設定温度まで上昇後に停止し、空気調和機のみが運転を継続する。経済性や使用者の好みで、暖房機を主暖房として使用し、空気調和機を特に寒いときや室内の空気を循環して部屋全体を暖めたいときに副暖房として使用する場合、空気調和機の発生する騒音と、暖房機が発生する騒音が重なりとても煩わしいものだった。 However, the device for performing two-way communication used in the heater of Patent Literature 1 is expensive and unsuitable for use in a general home. In addition, most heaters that are moved and used like a fan heater do not have a communication function.
Further, the fan heater disclosed in Patent Literature 2 stops after the room temperature rises to the set temperature of the fan heater, and only the air conditioner continues to operate. If the heater is used as the main heater for economical reasons or the user's preference, and the air conditioner is used as a sub-heater especially when it is cold or when it is desired to circulate indoor air and heat the entire room, And the noise generated by the heater overlapped with each other, which was very troublesome.

本発明は上記課題を解決するため、室内機上面に吸込口を、底面または前面に吹出口を形成し、前記室内機内に熱交換器と送風ファンと室温センサと制御部とを有し、他の暖房機の併用を考慮した併用運転モードの設定と、送風ファンの回転数や室外機の出力を自動で設定する自動運転モードの設定と、室温の設定や運転開始の操作を行う操作部と、設定状態を表示する表示部とを備えたリモコンを有し、前記制御部には、現在の室温Ｔと設定室温Ｔ０の温度差によって前記送風ファンの回転数を変更する送風ファン回転数設定部と、前記室外機へ信号を送る室外設定部と、前記室温センサの値を読み込んで記憶するメモリ装置とを備え、前記操作部にて併用運転モードが選択されている場合に、前記メモリ装置に記憶された第１の所定時間ｔ１前の室温Ｔ１と現在の室温Ｔを比較して、現在の室温Ｔが（室温Ｔ１＋所定温度差Ａ）より高いときには前記自動運転モードにて設定される送風ファン回転数Ｘよりも所定回転数Ｘ１低い回転数で前記送風ファンを運転する併用運転部を備えるようにした。   In order to solve the above-described problems, the present invention has a suction port on an upper surface of an indoor unit, an outlet on a bottom surface or a front surface, a heat exchanger, a blower fan, a room temperature sensor, and a control unit in the indoor unit. An operation unit that sets the combined operation mode that takes into account the combined use of heaters, sets the automatic operation mode that automatically sets the rotation speed of the blower fan and the output of the outdoor unit, and sets the room temperature and starts operation And a display unit for displaying a setting state. The control unit includes a blower fan rotation speed setting unit that changes the rotation speed of the blower fan according to a temperature difference between a current room temperature T and a set room temperature T0. An outdoor setting unit that sends a signal to the outdoor unit, and a memory device that reads and stores the value of the room temperature sensor, and when the combined operation mode is selected by the operation unit, the memory device First stored time stored Compare the previous room temperature T1 with the current room temperature T, and when the current room temperature T is higher than (room temperature T1 + predetermined temperature difference A), the predetermined rotation speed is higher than the blowing fan rotation speed X set in the automatic operation mode. X1 A combination operation unit for operating the blower fan at a low rotation speed is provided.

本発明に係る空気調和機においては、空気調和機が設置された室内で暖房機が運転しているときには、送風ファンの回転数を低下することで騒音を低減することができる。
空気調和機の検知する室温によって暖房機が運転中かどうかを空気調和機単独で判断することで、双方向通信装置を必要とせずに簡単に騒音を低減できる。 In the air conditioner according to the present invention, when the heater is operating in the room where the air conditioner is installed, noise can be reduced by reducing the rotation speed of the blower fan.
By determining whether or not the heater is operating based on the room temperature detected by the air conditioner, the noise can be easily reduced without the need for a two-way communication device.

And an operation mode switch 22 for selecting an operation mode such as a heating operation, a cooling operation, a dehumidification operation, and an automatic operation for automatically setting the outputs of the outdoor unit 11 and the blower fan 7 according to the room temperature. And a timer switch 23 for selecting a good morning timer or a good night timer. The display unit 18 allows a user to visually check whether an operation mode such as a set room temperature, heating, cooling, or the like, is selected by a liquid crystal panel, or a combined operation mode is selected by a combined operation switch 20.

２４はリモコン１６の受信装置で、リモコン１６から発信される運転信号や各種運転条件の設定を受信して制御部１０に伝達する。２５は送風ファン７を回転する室内送風モータで、ＤＣモータによって約７００〜１，６００ｒｐｍの範囲で多段階に回転数を可変する。２６は室内送風モータ２５の回転数を検知するモータセンサ。   Reference numeral 24 denotes a receiving device of the remote controller 16, which receives an operation signal transmitted from the remote controller 16 and setting of various operation conditions, and transmits them to the control unit 10. Reference numeral 25 denotes an indoor blower motor for rotating the blower fan 7, and the number of rotations can be varied in multiple stages within a range of about 700 to 1,600 rpm by a DC motor. 26 is a motor sensor for detecting the rotation speed of the indoor blower motor 25.

制御部１０には、室温センサ８で検知した現在の室温Ｔと、リモコン１６で設定された設定室温Ｔ０との温度差によって、送風ファン７の回転数を変更する送風ファン回転数設定部２７と、室外機１１の出力を設定する室外設定部２８と、室温センサ８の値を定期的に読み込んで記憶するメモリ装置２９を備えている。また、制御部１０には、併用運転スイッチ２０で暖房機２の併用運転モードが選択されたときに、第１の所定時間ｔ１（１時間）前の室温Ｔ１と現在の室温Ｔを比較して、室温Ｔが１時間前の室温Ｔ０より所定温度差Ａ（０．５ｄｅｇ）高い時には、既にファンヒータ２が運転を開始していると判断して、送風ファン７の騒音を小さくするために、自動運転モードで設定される送風ファン回転数Ｘよりも所定回転数Ｘ１（２００ｒｐｍ）低い回転数で送風ファン７を運転する併用運転部３０を備える。   The control unit 10 includes a blower fan rotation speed setting unit 27 that changes the rotation speed of the blower fan 7 according to the temperature difference between the current room temperature T detected by the room temperature sensor 8 and the set room temperature T0 set by the remote controller 16. An outdoor setting unit 28 for setting the output of the outdoor unit 11 and a memory device 29 for periodically reading and storing the value of the room temperature sensor 8. Further, when the combined operation mode of the heater 2 is selected by the combined operation switch 20, the control unit 10 compares the room temperature T1 before the first predetermined time t1 (one hour) with the current room temperature T. When the room temperature T is higher than the room temperature T0 one hour ago by a predetermined temperature difference A (0.5 deg), it is determined that the fan heater 2 has already started operation, and the noise of the blower fan 7 is reduced. The combined operation unit 30 is configured to operate the blower fan 7 at a rotation speed lower than the blower fan rotation speed X set in the automatic operation mode by a predetermined rotation speed X1 (200 rpm).

併用運転部３０は、メモリ装置２９に記憶された第１の所定時間ｔ１（１時間）より短い第２の所定時間ｔ２（１０分）前の室温Ｔ２と現在の室温Ｔを比較して、現在の室温Ｔが１０分前の室温Ｔ２よりも所定温度差Ａ（０．５ｄｅｇ）低いときには送風ファン７の回転数を上昇し、自動運転モードにて設定される送風ファン回転数Ｘよりも所定回転数Ｘ２（５０ｒｐｍ）低い回転数で運転することで、暖房能力を少し大きくして室温を上昇することで快適性を向上する。   The combined operation unit 30 compares the room temperature T2 before the second predetermined time t2 (10 minutes) shorter than the first predetermined time t1 (1 hour) stored in the memory device 29 with the current room temperature T, and When the room temperature T is lower than the room temperature T2 10 minutes ago by a predetermined temperature difference A (0.5 deg), the rotation speed of the blower fan 7 is increased, and the rotation speed of the blower fan 7 is more than the predetermined rotation speed X set in the automatic operation mode. By operating at a rotation speed lower by a number X2 (50 rpm), the heating capacity is slightly increased and the room temperature is raised to improve the comfort.

また、併用運転部３０は、現在の室温Ｔが更に低下して１０分前の室温Ｔ２よりも所定温度差Ｂ（１．０ｄｅｇ）低いときには、送風ファン７の回転数を更に上昇し、自動運転モードにて設定される送風ファン回転数Ｘに変更するることで、室温の上昇を優先し、ファンヒータ２と空気調和機１で室温を上昇させ室内の快適性を向上する。   When the current room temperature T further decreases and is lower by a predetermined temperature difference B (1.0 deg) than the room temperature T2 10 minutes ago, the combined operation unit 30 further increases the rotation speed of the blower fan 7 and performs the automatic operation. By changing to the blower fan speed X set in the mode, the room temperature is raised by the fan heater 2 and the air conditioner 1 by giving priority to the room temperature increase, and the indoor comfort is improved.

制御部１０の入力側には受信装置２４や室温センサ８、モータセンサ２６等が接続されている。制御部１０の出力側には送風モータ２５や室外機１１の室外制御部（図示せず）等が接続されている。   The receiving unit 24, the room temperature sensor 8, the motor sensor 26, and the like are connected to the input side of the control unit 10. The output side of the control unit 10 is connected to a blower motor 25, an outdoor control unit (not shown) of the outdoor unit 11, and the like.

図４は暖房自動運転時の送風ファン回転数Ｘを示す表で、本実施形態では送風ファン７の回転数は強・中・弱（３・２・１）の三段階とし、現在の室温Ｔが設定室温Ｔ０よりも２．０ｄｅｇ以上低いときには室温Ｔを早く上昇するために、送風ファン７はフル運転の１，６００ｒｐｍで運転し、室温Ｔが上昇し、設定室温Ｔ０よりも２．０〜１．０ｄｅｇの間は、送風ファン７は中の１，１００ｒｐｍで運転し、設定室温Ｔ０よりも０．５ｄｅｇまで上昇したときには、送風ファン７は弱の７００ｒｐｍで騒音もほとんど無く運転できる。   FIG. 4 is a table showing the number of rotations of the blower fan X during the automatic heating operation. In this embodiment, the number of rotations of the blower fan 7 is set to three stages of strong, medium, and weak (3.2.1), and the current room temperature T Is lower than the set room temperature T0 by 2.0 deg or more, in order to raise the room temperature T quickly, the blower fan 7 is operated at a full operation of 1,600 rpm, and the room temperature T rises, and is 2.0 to 2.0 degrees lower than the set room temperature T0. During 1.0 deg, the blower fan 7 operates at the medium speed of 1,100 rpm, and when the temperature rises to 0.5 deg from the set room temperature T0, the blower fan 7 can operate at 700 rpm, which is weak, with almost no noise.

図３のフローチャートで、ファンヒータ２を主暖房で運転し、空気調和機１を補助暖房として使用した場合の、空気調和機１の暖房併用運転について説明する。
リモコン１６で空気調和機１の運転を開始すれば（ｓ１）、ｓ２にて併用運転モードが選択されているかを判断する。併用運転モードは使用者が予め室内のファンヒータ２を主暖房として使用するかどうかを、使用者の好みに応じて設定する。併用運転モードを行わないＮｏの場合には、ｓ９に進んで通常の暖房自動運転を実施する。ｓ２にて併用運転モードを実施するＹｅｓの場合には、ｓ３に進む。 With reference to the flowchart of FIG. 3, a description will be given of a combined heating operation of the air conditioner 1 when the fan heater 2 is operated for main heating and the air conditioner 1 is used as auxiliary heating.
When the operation of the air conditioner 1 is started with the remote controller 16 (s1), it is determined whether or not the combined operation mode is selected in s2. In the combined operation mode, whether or not the user uses the indoor fan heater 2 as main heating in advance is set according to the user's preference. In the case of No in which the combined operation mode is not performed, the process proceeds to s9, and the normal heating automatic operation is performed. In the case of Yes for executing the combined operation mode in s2, the process proceeds to s3.

ｓ３ではすでに室内でファンヒータ２が運転中であるかどうかを判断する。１時間前の室温Ｔ１よりも現在の室温Ｔが０．５ｄｅｇ上昇していなければ、ファンヒータ２が燃料切れや別の部屋で使用されている等で暖房運転が行われていないので空気調和機１のみでフル運転の必要が有り、Ｎｏでｓ９に進んで通常の暖房自動運転を実施する。室温Ｔ１よりも現在の室温Ｔが０．５ｄｅｇ上昇していれば、既にファンヒータ２が室内で運転されているので、Ｙｅｓでｓ４に進み、空気調和機１はフル運転する必要が無いので送風ファン７の回転数を通常の自動運転の回転数Ｘよりも２００ｒｐｍ低くすることで室内機３から発生する風切り音の騒音を小さくし、ｓ５に進む。   In s3, it is determined whether the fan heater 2 is already operating indoors. If the current room temperature T does not increase by 0.5 deg from the room temperature T1 one hour ago, the heating operation is not performed because the fan heater 2 is out of fuel or is being used in another room. If only 1, it is necessary to perform the full operation, and if No, the process proceeds to s9 to perform the normal heating automatic operation. If the current room temperature T is higher than the room temperature T1 by 0.5 deg, the fan heater 2 has already been operated indoors, so the process proceeds to s4 at Yes, and the air conditioner 1 does not need to be fully operated, so the air is blown. By reducing the rotation speed of the fan 7 by 200 rpm from the rotation speed X of the normal automatic operation, the noise of the wind noise generated from the indoor unit 3 is reduced, and the process proceeds to s5.

ｓ５では室温Ｔが、１０分前の室温Ｔ２よりも下降しているかを判断する。室温Ｔが下降傾向にない場合は、Ｎｏでｓ４に戻り運転を継続します。室温Ｔが、室温Ｔ２よりも０．５ｄｅｇ下降しているときには、Ｙｅｓでｓ６に進み、これ以上室温Ｔが低下することを防止するために、送風ファン７の回転数を（回転数Ｘ−５０ｒｐｍ）まで上昇することで空気調和機１の暖房出力を向上させ、ｓ７に進む。   In s5, it is determined whether the room temperature T is lower than the room temperature T2 10 minutes before. If the room temperature T does not decrease, return to s4 with No and continue operation. When the room temperature T is lower than the room temperature T2 by 0.5 deg, the process proceeds to s6 with Yes, and in order to prevent the room temperature T from lowering further, the rotation speed of the blower fan 7 is set to (rotation speed X−50 rpm). ), The heating output of the air conditioner 1 is improved, and the process proceeds to s7.

ｓ７では室温Ｔが、１０分前の室温Ｔ２よりも上昇したかを判断する。室温Ｔが上昇して、Ｔ２よりも高いときには、Ｙｅｓでｓ４に戻って送風ファン７の回転数を下げて空気調和機１の出力を下げ騒音を低下させる。室温Ｔが上昇しないときには、Ｎｏでｓ８に進む。   In s7, it is determined whether or not the room temperature T has increased from the room temperature T2 10 minutes before. When the room temperature T rises and is higher than T2, the process returns to s4 in Yes to decrease the rotation speed of the blower fan 7 to reduce the output of the air conditioner 1 and reduce noise. If the room temperature T does not rise, the process proceeds to s8 with No.

ｓ８では室温Ｔが更に低下しているかを判断する。室温Ｔが、１０分前の室温Ｔ２よりも更に低下して１．０ｄｅｇよりも低くなったときには、ファンヒータ２の燃料切れ等によって停止したり、使用者の都合で別の部屋の暖房用にファンヒータ２が移動されてファンヒータ２による暖房が停止されたと判断し、Ｙｅｓでｓ９に進んで、通常の自動暖房運転に戻って、空気調和機１の単独暖房に移行する。室温Ｔの更なる低下が無いときには、Ｎｏでｓ６に戻って暖房運転を継続する。   In s8, it is determined whether or not the room temperature T has further decreased. When the room temperature T is further lower than the room temperature T2 of 10 minutes before and becomes lower than 1.0 deg, the fan heater 2 stops running due to running out of fuel or the like, or is used for heating another room at the convenience of the user. It is determined that the fan heater 2 has been moved and the heating by the fan heater 2 has been stopped, and the control advances to s9 in Yes, returns to the normal automatic heating operation, and shifts to the independent heating of the air conditioner 1. If there is no further decrease in the room temperature T, the process returns to s6 with No and continues the heating operation.

このように、本発明では空気調和機１が設置された室内でファンヒータ（暖房機）２が運転しているときには、送風ファン７の回転数を通常の自動暖房運転モードの回転数Ｘよりも低下することで騒音を低減することができる。
また、空気調和機１の検知する室温Ｔによってファンヒータ（暖房機）２が運転中かどうかを空気調和機１単独で判断することで、双方向通信装置を必要とせずに簡単に騒音を低減できる。
また、ファンヒータ（暖房機）２が燃料切れ等で停止したときには、室温Ｔの低下によって空気調和機１が単独で判断して空気調和機１の自動暖房運転モードに移行することで、室温の急激な低下を防止できる。 As described above, according to the present invention, when the fan heater (heating device) 2 is operating in the room where the air conditioner 1 is installed, the rotation speed of the blower fan 7 is set to be smaller than the rotation speed X in the normal automatic heating operation mode. The noise can be reduced by lowering the noise.
Also, by determining whether the fan heater (heating device) 2 is operating based on the room temperature T detected by the air conditioner 1 alone, the noise can be easily reduced without requiring a two-way communication device. it can.
Further, when the fan heater (heater) 2 is stopped due to running out of fuel or the like, the air conditioner 1 determines independently by the decrease in the room temperature T and shifts to the automatic heating operation mode of the air conditioner 1, thereby reducing the room temperature. A sharp drop can be prevented.

なお、本発明は上記一実施形態に限定されるものではなく、室内機３の大きさや空気調和機１の出力等の特性に応じて、所定温度差Ａや所定温度差Ｂの値や、送風ファン７の回転数を適宜変化して設定できるものであり、発明の要旨を変更しない範囲で改変可能なものである。   Note that the present invention is not limited to the above-described embodiment, and the values of the predetermined temperature difference A and the predetermined temperature difference B, The number of revolutions of the fan 7 can be set by appropriately changing it, and can be changed without changing the gist of the invention.
