Description

本発明は上下風向変更羽根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 provided with vertical wind direction changing blades.

一般に空気調和機は、上下風向変更羽根を上下動させて空気の向きを変更し、室内を冷房もしくは暖房するが、その上下風向変更羽根には冷房時に結露が生じやすい。よって、結露が生じないよう結露防止対策が施してある(例えば、特許文献1参照)。 Generally, in an air conditioner, the vertical wind direction changing blades are moved up and down to change the direction of air to cool or heat the room, but the vertical wind direction changing blades are liable to cause dew condensation during cooling. Therefore, dew condensation prevention measures are taken to prevent dew condensation (see, for example, Patent Document 1).

図20(a)は上記特許文献1記載の空気調和機を示し、この空気調和機は本体100の吹出口101に設けた上下風向変更羽根102を吹出口域内に軸支して、熱交換器103で熱交換した冷風が上下風向変更羽根102の上下両面を流れるようにし結露を防止している。 FIG. 20A shows the air conditioner described in Patent Document 1, which is a heat exchanger in which the vertical wind direction changing blades 102 provided at the outlet 101 of the main body 100 are pivotally supported in the outlet region. The cold air that has exchanged heat in 103 flows through both the upper and lower surfaces of the upper and lower wind direction changing blades 102 to prevent dew condensation.

また図20(b)は同特許文献1の段落0005に記載されている上下風向変更羽根の結露防止構成を示し、この構成は上下風向変更羽根112を中空筒状に形成して、上下風向変更羽根112の上下面間に生じる温度差を少なくし結露を防止している。 Further, FIG. 20B shows a dew condensation prevention configuration of the vertical wind direction changing blades described in paragraph 0005 of Patent Document 1, and this configuration is such that the vertical wind direction changing blades 112 are formed in a hollow tubular shape to change the vertical wind direction. The temperature difference between the upper and lower surfaces of the blade 112 is reduced to prevent dew condensation.

特開2014−122750号公報Japanese Unexamined Patent Publication No. 2014-122750

しかしながら、上記特許文献1(a)の構成によると、上下風向変更羽根102が吹出口101の吹出口域内に軸支されているため、送風の抵抗体となるとともに、上下風向変更羽根102がリアガイダ105の延長上に位置しない形となって上下風向変更羽根102による整流効果も悪くなる。よって、吹出口101から吹き出す空気の送風性能が悪化して大風量が出せず、大風量による迅速かつ効果的な冷房又は暖房が困難である、という課題があった。 However, according to the configuration of Patent Document 1 (a), since the vertical wind direction changing blade 102 is pivotally supported in the air outlet region of the air outlet 101, it serves as a blower resistor and the vertical wind direction changing blade 102 is a rear guider. The shape is not located on the extension of 105, and the rectifying effect of the vertical wind direction changing blade 102 is also deteriorated. Therefore, there is a problem that the air blowing performance of the air blown out from the outlet 101 deteriorates and a large air volume cannot be generated, and it is difficult to quickly and effectively cool or heat the air by the large air volume.

また、上記特許文献1(b)の中空羽根方式の構成では、上下風向変更羽根112は上下面二つの部品を接合して中空状にするので、結露を防止することはできるものの、特許文献1(a)に示すような一枚物の上下風向変更羽根に比べ材料費、接合工数が余分に必要となり、しかも、上下風向変更羽根112の重量が増すため、これを駆動するモータ等の駆動源の能力アップあるいはギアボックスの付設によるトルクアップが必要となる等、大幅なコストアップを招く、という課題があった。 Further, in the hollow blade system configuration of Patent Document 1 (b), since the vertical wind direction changing blade 112 is made hollow by joining two parts on the upper and lower surfaces, dew condensation can be prevented, but Patent Document 1 Compared to a single piece of vertical wind direction changing blades as shown in (a), extra material costs and joining steps are required, and the weight of the vertical wind direction changing blades 112 increases, so a drive source for a motor or the like that drives them. There was a problem that it would lead to a significant cost increase, such as the need to increase the capacity of the engine or increase the torque by attaching a gearbox.

上記課題のうち、前記した送風性能悪化の課題は、図21に示す特開2014−196882号公報記載のように、上下風向変更羽根122をリアガイダ105の先端部105aに軸支して、上下風向変更羽根122がリアガイダ105の延長線上に位置するようにすれば解決することができる。これは、上下風向変更羽根122がリアガイダ105の延長線上に位置することによって上下風向変更羽根122の整流効果とディフーザ機能が最大限発揮されることによるもので、送風性能が大きく改善され向上する。 Among the above-mentioned problems, the problem of deterioration of the ventilation performance is as described in Japanese Patent Application Laid-Open No. 2014-196882 shown in FIG. This can be solved by arranging the changing blade 122 on the extension line of the rear guider 105. This is because the vertical wind direction changing blade 122 is located on the extension line of the rear guider 105 so that the rectifying effect and the diffuser function of the vertical wind direction changing blade 122 are maximized, and the ventilation performance is greatly improved and improved.

しかしながらこの場合、上下風向変更羽根122の下面に沿って冷風を流すことが困難なため、結露防止のためには上下風向変更羽根122を中空筒状に形成しなければならず、特許文献1(b)記載のようなコストアップ問題が残ることになる。 However, in this case, since it is difficult to allow cold air to flow along the lower surface of the vertical wind direction changing blade 122, the vertical wind direction changing blade 122 must be formed in a hollow tubular shape in order to prevent dew condensation. b) The problem of cost increase as described will remain.

本発明はこのような点に鑑みてなしたもので、上下風向変更羽根の結露を防止するとともに風量低下を抑制して大風量化も可能な高品質、高性能な空気調和機を提供することを第1の目的とし、更には前記風量低下を抑制した時にも結露防止して、安価で高品質、高性能な空気調和機とすることを第2の目的としたものである。 The present invention has been made in view of these points, and provides a high-quality, high-performance air conditioner capable of preventing dew condensation on the vertical wind direction changing blades, suppressing a decrease in air volume, and increasing the air volume. The first purpose is to prevent dew condensation even when the decrease in air volume is suppressed, and to obtain an inexpensive, high-quality, high-performance air conditioner.

本発明は上記第1の目的を達成するため、本体と、本体内に設けた熱交換器と、前記熱交換器で熱交換した空気を送風するファンと、前記ファンからの空気を案内する送風路と、前記送風路からの空気を吹き出す吹出口と、前記吹出口に設けた上下風向変更羽根と、前記上下風向変更羽根を軸支したリンク機構と、前記リンク機構を介して前記上下風向変更羽根を上下方向に駆動する駆動手段と、前記駆動手段を制御する制御部とを備え、前記リンク機構は、吹出口の吹出口域内を軸支点として上下風向変更羽根を上下回動自在なる如く軸支するとともに、上記上下風向変更羽根の軸支点を変位させて前記上下風向変更羽根を前記送風路のリアガイダ延長線上に設定可能とした構成としてある。 In order to achieve the first object, the present invention has a main body, a heat exchanger provided in the main body, a fan that blows air exchanged by the heat exchanger, and a blower that guides the air from the fan. The path, the air outlet that blows out air from the air passage, the vertical air direction changing blades provided at the air outlet, the link mechanism that pivotally supports the vertical air direction changing blade, and the vertical air direction change via the link mechanism. The link mechanism includes a driving means for driving the blades in the vertical direction and a control unit for controlling the driving means, and the link mechanism has a shaft so that the vertical wind direction changing blades can rotate up and down with the inside of the outlet region of the outlet as a shaft fulcrum. In addition to supporting the blades, the shaft fulcrum of the vertical wind direction changing blades can be displaced so that the vertical wind direction changing blades can be set on the rear guider extension line of the air passage.

これにより、上下風向変更羽根は通常その軸支点を吹出口域内に位置させて回動させ、上下風向変更羽根の上下面に熱交換後の空気が流れるようにして結露を防止することができる。しかも、上記上下風向変更羽根の軸支点を変位させれば上下風向変更羽根を送風路のリアガイダ延長線上に位置させて高い整流効果を発揮させ、その送風性能を向上させて大風量化することができ、大風量による冷房等の空調を実現することができる。 As a result, the vertical wind direction changing blade is usually rotated with its shaft fulcrum located in the air outlet region, and the air after heat exchange flows through the upper and lower surfaces of the vertical wind direction changing blade to prevent dew condensation. Moreover, if the shaft fulcrum of the vertical wind direction changing blade is displaced, the vertical wind direction changing blade can be positioned on the rear guider extension line of the air passage to exert a high rectifying effect, improve the air blowing performance, and increase the air volume. It is possible to realize air conditioning such as cooling with a large air volume.

本発明は上記構成により、上下風向変更羽根の結露を防止すると同時に風量低下も抑制して送風性能を向上させ大風量による空調を実現することができ、高品質、高性能な空気調和機とすることができる。 The present invention provides a high-quality, high-performance air conditioner capable of preventing dew condensation on the vertical wind direction changing blades and at the same time suppressing a decrease in air volume to improve air blowing performance and realize air conditioning with a large air volume. be able to.

第1の発明は、本体と、本体内に設けた熱交換器と、前記熱交換器で熱交換した空気を送風するファンと、前記ファンからの空気を案内する送風路と、前記送風路からの空気を吹き出す吹出口と、前記吹出口に設けた上下風向変更羽根と、前記上下風向変更羽根を軸支したリンク機構と、前記リンク機構を介して前記上下風向変更羽根を上下方向に駆動する駆動手段と、前記駆動手段を制御する制御部とを備え、前記リンク機構は、吹出口の吹出口域内を軸支点として上下風向変更羽根を上下回動自在なる如く軸支するとともに、上記上下風向変更羽根の軸支点を変位させて前記上下風向変更羽根を前記送風路のリアガイダ延長線上に設定可能とした構成としてある。 The first invention is from a main body, a heat exchanger provided in the main body, a fan that blows air exchanged by the heat exchanger, an air passage that guides air from the fan, and the air passage. The vertical wind direction changing blades are driven in the vertical direction via the air outlet, the vertical wind direction changing blades provided at the air outlet, the link mechanism that pivotally supports the vertical wind direction changing blades, and the link mechanism. The link mechanism includes a drive means and a control unit that controls the drive means, and the link mechanism pivotally supports the vertical wind direction changing vanes so as to be vertically rotatable with the inside of the air outlet area of the air outlet as a shaft fulcrum, and the vertical wind direction. The shaft fulcrum of the changing blade is displaced so that the vertical wind direction changing blade can be set on the rear guider extension line of the air passage.

これにより、上下風向変更羽根は通常その軸支点を吹出口域内に位置させて回動させ、上下風向変更羽根の上下面に熱交換後の空気が流れるようにして結露を防止することができる。しかも、上記上下風向変更羽根の軸支点を変位させれば上下風向変更羽根を送風路のリアガイダ延長線上に位置させて高い整流効果を発揮させ、その送風性能を向上させて大風量化することができ、大風量による冷房等の空調を実現することができる。 As a result, the vertical wind direction changing blade is usually rotated with its shaft fulcrum located in the air outlet region, and the air after heat exchange flows through the upper and lower surfaces of the vertical wind direction changing blade to prevent dew condensation. Moreover, if the shaft fulcrum of the vertical wind direction changing blade is displaced, the vertical wind direction changing blade can be positioned on the rear guider extension line of the air passage to exert a high rectifying effect, improve the air blowing performance, and increase the air volume. It is possible to realize air conditioning such as cooling with a large air volume.

第2の発明は、第1の発明において、前記制御部は、上下風向変更羽根を送風路のリアガイダ延長線上に位置させたときに吹出空気の温度を露点温度以上とする構成としてある。 In the second invention, in the first invention, the control unit has a configuration in which the temperature of the blown air is set to the dew point temperature or higher when the vertical wind direction changing blades are positioned on the rear guider extension line of the air passage.

これにより、上下風向変更羽根を送風路のリアガイダ延長線上に位置させて大風量化した時、吹出空気の温度を露点温度以上として結露を防止でき、一枚物の軽量且つ簡易で安価な上下風向変更羽根として結露を防止しつつ大風量による冷房等の空調を実現することができる。 As a result, when the vertical wind direction changing blades are positioned on the rear guider extension line of the air passage to increase the air volume, the temperature of the blown air is set above the dew point temperature to prevent dew condensation, and a single piece of lightweight, simple and inexpensive vertical wind direction can be prevented. As a changing blade, it is possible to realize air conditioning such as cooling with a large air volume while preventing dew condensation.

第3の発明は、第1又は第2の発明において、前記リンク機構は、駆動手段の回転軸を回転中心として回転駆動される駆動アームと、前記駆動アームによって駆動される上下風向変更羽根アームと、前記上下風向変更羽根アームを支持するリンクアームとを備え、前記リンクアームは略く字状に形成してその一端側部分を空気調和機の本体に軸支するとともに、他端側部分を前記上下風向変更羽根アームの長手方向の途中部分に軸支して当該軸支点を中心に上下風向変更羽根アームを回動自在に軸支する構成とし、且つ、前記上下風向変更羽根アームはその先端部分を前記駆動アームに軸支して当該上下風向変更羽根アームの先端部分を前記駆動アームで回動する構成としてある。 A third aspect of the invention is the first or second aspect, wherein the link mechanism includes a drive arm that is rotationally driven around the rotation axis of the drive means and a vertical wind direction changing blade arm that is driven by the drive arm. A link arm for supporting the vertical wind direction changing blade arm is provided, and the link arm is formed in a substantially shape so that one end side portion thereof is pivotally supported by the main body of the air conditioner and the other end side portion is described above. The vertical wind direction changing blade arm is pivotally supported in the middle portion in the longitudinal direction of the vertical wind direction changing blade arm, and the vertical wind direction changing blade arm is rotatably supported around the shaft fulcrum, and the vertical wind direction changing blade arm is the tip portion thereof. Is pivotally supported by the drive arm, and the tip portion of the vertical wind direction changing blade arm is rotated by the drive arm.

これにより、リンクアームで軸支した上下風向変更羽根アームの軸支点を駆動アームの回転に伴い吹出口の吹出口域内に位置させて下風向変更羽根を回動させることができるとともに、前記上下風向変更羽根アームの軸支点を変位させて前記上下風向変更羽根をリアガイダ延長線上に位置させることができ、簡易なリンク機構によって確実に結露防止と送風性能向上による大風量化を実現することができる。 As a result, the shaft fulcrum of the vertical wind direction changing blade arm pivotally supported by the link arm can be positioned within the air outlet region of the air outlet as the drive arm rotates, and the downward wind direction changing blade can be rotated, and the vertical wind direction can be rotated. The shaft fulcrum of the changing blade arm can be displaced to position the vertical wind direction changing blade on the extension line of the rear guider, and a simple link mechanism can surely prevent dew condensation and increase the air volume by improving the ventilation performance.

第4の発明は第3の発明において、前記リンク機構は、駆動アームの回転中心をX、前記駆動アームと上下風向変更羽根アーム先端部との軸支点をY、前記上下風向変更羽根アームの長手方向途中とリンクアームとの軸支点をZとして、前記XとYとの間の距離をA、前記YとZとの間の距離をBとすると、B=A×(1.2〜1.5)となる構成としてある。 The fourth invention is the third invention, in the link mechanism, the rotation center of the drive arm is X, the axial fulcrum between the drive arm and the tip of the vertical wind direction changing blade arm is Y, and the longitudinal length of the vertical wind direction changing blade arm. Assuming that the axial fulcrum between the middle of the direction and the link arm is Z, the distance between X and Y is A, and the distance between Y and Z is B, B = A × (1.2 to 1. 5).

これにより、上記リンク機構は、上下風向変更羽根アームとリンクアームとの軸支点の移動が円滑なものとなるとともに、上下風向変更羽根の下向き回動範囲を大きくして空調範囲を広いものとすることができ、より高品質、高性能な空気調和機とすることができる。 As a result, the link mechanism facilitates the smooth movement of the shaft fulcrum between the vertical wind direction changing blade arm and the link arm, and increases the downward rotation range of the vertical wind direction changing blade to widen the air conditioning range. It can be a higher quality, higher performance air conditioner.

第5の発明は第1〜第4の発明において、前記駆動手段は、その回転軸に駆動アームを介することなく駆動手段直結型上下風向変更羽根の羽根アームを軸支して前記駆動手段直結型上下風向変更羽根を装着可能とした構成としてある。 Fifth invention is the first to fourth inventions, wherein the drive means is directly connected to the drive means by pivotally supporting the blade arm of the vertical wind direction changing blade without passing through the drive arm to the rotation shaft. It is configured so that the vertical wind direction changing blades can be attached.

これにより、リアガイダの延長線上に上下風向変更羽根を位置させて大風量運転が可能な空気調和機と、大風量運転機能を持たない普及型の空気調和機を提供することができ、タイプの異なる二種類の空気調和機を合理的かつ安価に提供することができる。 As a result, it is possible to provide an air conditioner capable of large air volume operation by locating the vertical wind direction changing blades on the extension line of the rear guider and a popular type air conditioner that does not have a large air volume operation function. Two types of air conditioners can be provided reasonably and inexpensively.

図5〜図9において、15は主上下風向変更羽根11aを上下に回動させる駆動手段となる羽根駆動モータで、吹出口8の吹出口枠16(図6、図8参照)に取り付けてあり、その回転軸15aは吹出口枠16の軸孔16aを貫通して吹出口8内に突出している。 In FIGS. 5 to 9, reference numeral 15 denotes a blade drive motor that serves as a driving means for rotating the main vertical wind direction changing blade 11a up and down, and is attached to the outlet frame 16 (see FIGS. 6 and 8) of the outlet 8. The rotating shaft 15a penetrates the shaft hole 16a of the air outlet frame 16 and projects into the air outlet 8.

17は前記羽根駆動モータ15の回転軸15aによって駆動される駆動アームで、略L字状に形成してあり、その根元側端部を前記羽根駆動モータ15の回転軸15aに嵌合させて連結してある。 Reference numeral 17 denotes a drive arm driven by the rotary shaft 15a of the blade drive motor 15, which is formed in a substantially L shape, and the root side end thereof is fitted to the rotary shaft 15a of the blade drive motor 15 and connected. It is done.

18は前記駆動アーム17の他端側に連結した上下風向変更羽根アームで、駆動アーム17によって回転駆動される。上記上下風向変更羽根アーム18はその長手方向が鈍角に屈曲形成されており、その先端部に設けた第1ピン軸18aを前記駆動アーム17の他端側のアームピン軸用孔17aに嵌合させて駆動アーム17に連結し、更に長手方向途中となる屈曲部分に設けた第2ピン軸18bをリンクアーム19に嵌合してこれに軸支させている。なお、上下風向変更羽根アーム18は主上下風向変更羽根11aに一体成型もしくは一体的に取り付け固定されている。 Reference numeral 18 denotes a vertical wind direction changing blade arm connected to the other end side of the drive arm 17, which is rotationally driven by the drive arm 17. The vertical wind direction changing blade arm 18 is bent at an obtuse angle in the longitudinal direction, and the first pin shaft 18a provided at the tip thereof is fitted into the arm pin shaft hole 17a on the other end side of the drive arm 17. A second pin shaft 18b provided at a bent portion in the middle of the longitudinal direction is fitted to the link arm 19 and is pivotally supported by the link arm 19. The vertical wind direction changing blade arm 18 is integrally molded or integrally attached and fixed to the main vertical wind direction changing blade 11a.

上記上下風向変更羽根アーム18を軸支するリンクアーム19は鋭角に屈曲する略く字状に形成されており、前記した如くその一端部側に設けたリンクピン軸用孔19aを前記上下風向変更羽根アーム18の第2ピン軸18bに嵌合させてこれを軸支するとともに、他端部側に設けたリンクピン軸19bを吹出口枠16に一体成型もしくは一体的に取り付け固定した軸受部20の軸受孔20aに嵌合させて軸支してある。 The link arm 19 that pivotally supports the vertical wind direction changing blade arm 18 is formed in a substantially abbreviated shape that bends at an acute angle, and as described above, the link pin shaft hole 19a provided on one end side thereof is used to change the vertical wind direction. The bearing portion 20 is fitted to the second pin shaft 18b of the blade arm 18 to support the shaft, and the link pin shaft 19b provided on the other end side is integrally molded or integrally attached to and fixed to the air outlet frame 16. It is fitted in the bearing hole 20a of the above and is pivotally supported.

これにより、このリンク機構14は、リンクアーム19のリンクピン軸用孔19aが軸支点、つまり回転中心となって、主上下風向変更羽根11aが上下に回動するとともに、上記主上下風向変更羽根11aの回転中心となる軸支点が変位することになる。 As a result, in the link mechanism 14, the link pin shaft hole 19a of the link arm 19 serves as a shaft fulcrum, that is, the center of rotation, and the main vertical wind direction changing blade 11a rotates up and down, and the main vertical wind direction changing blade The shaft fulcrum, which is the center of rotation of 11a, is displaced.

詳述すると、羽根駆動モータ15の駆動により駆動アーム17が回動し、駆動アーム17先端のアームピン軸用孔17aに嵌合させ軸支した第1ピン軸18aを介して上下風向変更羽根アーム18に回動力が加わる。上記上下風向変更羽根アーム18に回動力が加わると、当該上下風向変更羽根アーム18はその途中に設けた第2ピン軸18bをリンクアーム19のリンクピン軸用孔19aに軸支させているので、当該リンクアーム19のリンクピン軸用孔19a、つまり上下風向変更羽根アーム18途中の第2ピン軸18bを中心にして回動する。そして更に、上記上下風向変更羽根アーム18途中の第2ピン軸18bを軸支しているリンクアーム19は、その他端側部分を吹出口枠16の軸受部20に軸支しているので、上下風向変更羽根アーム18途中の第2ピン軸18b、つまり軸支点が、前記駆動アーム17の回動による上下風向変更羽根アーム18の回動に伴ってその位置を変位することになる。 More specifically, the drive arm 17 is rotated by the drive of the blade drive motor 15, and the vertical wind direction changing blade arm 18 is fitted through the arm pin shaft hole 17a at the tip of the drive arm 17 and is pivotally supported via the first pin shaft 18a. Power is added to. When rotational power is applied to the vertical wind direction changing blade arm 18, the vertical wind direction changing blade arm 18 pivotally supports the second pin shaft 18b provided in the middle of the vertical wind direction changing blade arm 18 in the link pin shaft hole 19a of the link arm 19. , The link pin shaft hole 19a of the link arm 19, that is, the second pin shaft 18b in the middle of the vertical wind direction changing blade arm 18 rotates. Further, the link arm 19 that pivotally supports the second pin shaft 18b in the middle of the vertical wind direction changing blade arm 18 has the other end side portion pivotally supported by the bearing portion 20 of the air outlet frame 16, so that the link arm 19 is vertically supported. The second pin shaft 18b in the middle of the wind direction changing blade arm 18, that is, the shaft fulcrum, is displaced in position as the vertical wind direction changing blade arm 18 rotates due to the rotation of the drive arm 17.

そして、上記のように構成したリンク機構14は、この例では、図9に示すように、更に前記駆動アーム17の前記回転軸15aへの嵌合部、すなわち駆動アーム17の回転中心をX、前記駆動アーム17と上下風向変更羽根アーム18との軸支点をY、前記上下風向変更羽根アーム18の長手方向途中とリンクアーム19との軸支点をZとして、前記XとYとの間の距離をA、前記YとZとの間の距離をBとすると、B=A×(1.2〜1.5)となる構成としてある。 Then, in this example, in the link mechanism 14 configured as described above, as shown in FIG. 9, the fitting portion of the drive arm 17 to the rotation shaft 15a, that is, the rotation center of the drive arm 17 is set to X. The distance between X and Y, where Y is the axial fulcrum between the drive arm 17 and the vertical wind direction changing blade arm 18, and Z is the axial fulcrum between the longitudinal direction of the vertical wind direction changing blade arm 18 and the link arm 19. Is A, and the distance between Y and Z is B, B = A × (1.2 to 1.5).

次に上記のように構成したリンク機構14により駆動される主上下風向変更羽根11aの駆動制御について図10〜図12を用いて説明する。 Next, the drive control of the main vertical wind direction changing blades 11a driven by the link mechanism 14 configured as described above will be described with reference to FIGS. 10 to 12.

図10は主上下風向変更羽根の制御ブロック図、図11、図12はその制御フロー図である。 FIG. 10 is a control block diagram of the main vertical wind direction changing blade, and FIGS. 11 and 12 are control flow diagrams thereof.

図10において、21は羽根駆動モータ15を介してリンク機構14を動作させて主上下風向変更羽根11aを上下動させる制御部で、リンク機構14を駆動する羽根駆動モータ15及び吹出口8から空気を吹き出させるファン6のファンモータ22を駆動制御する。この駆動制御は、吸込み風温度センサ23、吹出し風温度センサ24、湿度センサ25からの出力に基づき制御部21が行う。その制御フローは図11、図12に示す通りで、後に詳述する。 In FIG. 10, reference numeral 21 denotes a control unit that operates the link mechanism 14 via the blade drive motor 15 to move the main vertical wind direction changing blade 11a up and down, and air from the blade drive motor 15 that drives the link mechanism 14 and the air outlet 8. The fan motor 22 of the fan 6 that blows out the fan 6 is driven and controlled. This drive control is performed by the control unit 21 based on the outputs from the suction air temperature sensor 23, the blow air temperature sensor 24, and the humidity sensor 25. The control flow is as shown in FIGS. 11 and 12, and will be described in detail later.

次に上記のように構成した空気調和機の作用効果について、図13〜図16を用い冷房運転時の動作を例にして説明する。尚、空気調和機における上下の風向制御は、この例の場合は主上下風向変更羽根11aと補助上下風向変更羽根11bとによって行うが、本発明の対象となるのは主上下風向変更羽根11aによる風向制御であるので、この主上下風向変更羽根11aによる動作について図13〜図16を用い説明する。 Next, the operation and effect of the air conditioner configured as described above will be described with reference to FIGS. 13 to 16 by taking the operation during the cooling operation as an example. In the case of this example, the vertical wind direction control in the air conditioner is performed by the main vertical wind direction changing blade 11a and the auxiliary vertical wind direction changing blade 11b, but the subject of the present invention is the main vertical wind direction changing blade 11a. Since the wind direction is controlled, the operation of the main vertical wind direction changing blades 11a will be described with reference to FIGS. 13 to 16.

図13は運転開始前の吹出口閉時の断面図、図14は冷房運転時における斜め下気流モードにおける断面図、図15は同冷房運転時における天井気流モード時の断面図、図16(a)(b)(c)は同空気調和機の室内機の大風量運転移行時における主上下風向変更羽根の回動推移を示す断面図である。 13 is a cross-sectional view when the air outlet is closed before the start of operation, FIG. 14 is a cross-sectional view in the oblique downdraft mode during the cooling operation, and FIG. 15 is a cross-sectional view in the ceiling airflow mode during the cooling operation, FIG. 16 (a). ) (B) and (c) are cross-sectional views showing the rotation transition of the main vertical wind direction changing blades at the time of shifting to the large air volume operation of the indoor unit of the air conditioner.

空気調和機は、図13に示す吹出口閉時、主上下風向変更羽根11aで吹出口8を閉じており、リンクアーム19のリンクピン軸用孔19aに軸支した上下風向変更羽根アーム18の第2ピン軸18b、つまり軸支点Zは、吹出口8の吹出口枠域内に位置している。 In the air conditioner, when the air outlet shown in FIG. 13 is closed, the air outlet 8 is closed by the main vertical wind direction changing blades 11a, and the vertical wind direction changing blade arm 18 pivotally supported by the link pin shaft hole 19a of the link arm 19. The second pin shaft 18b, that is, the shaft fulcrum Z is located within the air outlet frame area of the air outlet 8.

空調運転が開始され、羽根駆動モータ15が駆動されると、主上下風向変更羽根11aはリンク機構14の軸支点Zを中心に回動し吹出口8を開放するとともに、ユーザによって設定された運転モードにより決定される角度に設定する。そして、ファン6が駆動され、上面開口部2bよりフィルタ4を介して室内空気が室内機1の内部に取り入れられる。 When the air conditioning operation is started and the blade drive motor 15 is driven, the main vertical wind direction changing blade 11a rotates around the shaft fulcrum Z of the link mechanism 14 to open the air outlet 8 and the operation set by the user. Set to the angle determined by the mode. Then, the fan 6 is driven, and the indoor air is taken into the indoor unit 1 from the upper surface opening 2b through the filter 4.

取り入れられた室内空気は、熱交換器5において熱交換されて冷風となり、ファン6に吸い込まれる。ファン6に吸い込まれた冷風は、ファン6の下流側に形成された送風路7のリアガイダ9およびスタビライザ10に案内されて、吹出口8から吹き出される。 The taken-in indoor air is heat-exchanged in the heat exchanger 5 to become cold air, which is sucked into the fan 6. The cold air sucked into the fan 6 is guided by the rear guider 9 and the stabilizer 10 of the air passage 7 formed on the downstream side of the fan 6 and blown out from the air outlet 8.

吹出口8から吹き出される冷風は、上下風向変更羽根11の主上下風向変更羽根11aと補助上下風向変更羽根11b及び左右風向変更羽根12によりその吹き出し方向が制御される。 The direction of the cold air blown out from the air outlet 8 is controlled by the main vertical wind direction changing blades 11a of the vertical wind direction changing blades 11, the auxiliary vertical wind direction changing blades 11b, and the left and right wind direction changing blades 12.

図14は冷風を斜め下向きに吹き出す主上下風向変更羽根の位置、図15は部屋が十分に冷えユーザに直接気流を当てないよう冷風を正面に向けて吹き出す主上下風向変更羽根の位置を示し、送風路7からの冷風を所定方向に変更する。 FIG. 14 shows the position of the main vertical wind direction changing blade that blows cold air diagonally downward, and FIG. 15 shows the position of the main vertical wind direction changing blade that blows cold air toward the front so that the room is sufficiently cold and the airflow is not directly applied to the user. The cold air from the air passage 7 is changed in a predetermined direction.

この時、上記主上下風向変更羽根11aを軸支するリンク機構14は、いずれの場合もその主上下風向変更羽根11aの軸支点Zを吹出口8の吹出口域内に位置させており、送風路7からの冷風は主上下風向変更羽根11aの上面とともに下面側にも流れる。これにより、主上下風向変更羽根11aに結露が発生するのを防止されている。 At this time, in each case, the link mechanism 14 that pivotally supports the main vertical wind direction changing blade 11a positions the shaft fulcrum Z of the main vertical wind direction changing blade 11a within the air outlet region of the air outlet 8. The cold air from No. 7 flows to the lower surface side as well as the upper surface side of the main vertical wind direction changing blade 11a. This prevents dew condensation from forming on the main vertical wind direction changing blades 11a.

つまり、通常の冷房運転時は、主上下風向変更羽根11aの軸支点Zを吹出口8の吹出口域内に位置させて主上下風向変更羽根11aを回動させることにより主上下風向変更羽根11aの上下面に熱交換後の冷風が流れるようにして結露を防止している。 That is, during normal cooling operation, the shaft fulcrum Z of the main vertical wind direction changing blade 11a is positioned within the air outlet region of the air outlet 8 and the main vertical wind direction changing blade 11a is rotated to rotate the main vertical wind direction changing blade 11a. Condensation is prevented by allowing cold air after heat exchange to flow on the upper and lower surfaces.

次に大風量にして運転する時の動作について説明する。 Next, the operation when operating with a large air volume will be described.

この大風量による運転は例えばユーザが制御部21に設定してある大風量運転モードを選択することによってファン6からの風量が最大になるようにして行うが、前記したように主上下風向変更羽根11aの軸支点Zが吹出口域内に位置していると風路抵抗体となって大風量を確保することができない。 The operation with this large air volume is performed so that the air volume from the fan 6 is maximized by, for example, selecting the large air volume operation mode set in the control unit 21 by the user. If the shaft fulcrum Z of 11a is located in the air outlet region, it becomes an air passage resistor and a large air volume cannot be secured.

しかしながら、本実施の形態の空気調和機は、大風量運転モードを選択して運転を開始すると、羽根駆動モータ15がリンク機構14の駆動アーム17を図14、図15で示す通常時の位置よりも更に回動させる。これにより、図16に示す大風量運転移行時における主上下風向変更羽根11aの回動推移の(b)に示すように、主上下風向変更羽根11aが大きく下向き回動しつつその軸支点Zが図16(c)に示すように送風路7を形成するリアガイダ9の先端部分に移動し変位する。そして、主上下風向変更羽根11aはリアガイダ9の延長線上に位置する形となる。 However, in the air conditioner of the present embodiment, when the large air volume operation mode is selected and the operation is started, the blade drive motor 15 moves the drive arm 17 of the link mechanism 14 from the normal position shown in FIGS. 14 and 15. Is also rotated further. As a result, as shown in (b) of the rotation transition of the main vertical wind direction changing blades 11a at the time of transition to the large air volume operation shown in FIG. 16, the main vertical wind direction changing blades 11a rotate largely downward and the shaft fulcrum Z becomes As shown in FIG. 16 (c), it moves to and displaces the tip portion of the rear guider 9 forming the air passage 7. Then, the main vertical wind direction changing blades 11a are located on the extension line of the rear guider 9.

したがって、主上下風向変更羽根11aは送風路7のリアガイダ延長線上に位置して高い整流効果を発揮し送風性能を大きく向上させる。よって、主上下風向変更羽根11aの軸支点Zが吹出口8の吹出口域内に位置している場合に比べファン6の性能を従来通りとしたまま大風量化することができ、迅速かつ効果的な空調を実現することができる。 Therefore, the main vertical wind direction changing blades 11a are located on the rear guider extension line of the air passage 7, exhibit a high rectifying effect, and greatly improve the air blowing performance. Therefore, compared to the case where the shaft fulcrum Z of the main vertical wind direction changing blade 11a is located in the outlet region of the outlet 8, the performance of the fan 6 can be increased as before, which is quick and effective. Air conditioning can be realized.

そして、本実施の形態では、上記主上下風向変更羽根11aを送風路7のリアガイダ延長線上に位置させたとき、制御部21は主上下風向変更羽根11aの上下面の空気の温度を露点温度以上とする。したがって、結露発生を防止できる。その動作を更に図11の制御フロー図を用いて説明する。 Then, in the present embodiment, when the main vertical wind direction changing blade 11a is positioned on the rear guider extension line of the air passage 7, the control unit 21 sets the temperature of the air on the upper and lower surfaces of the main vertical wind direction changing blade 11a to be equal to or higher than the dew point temperature. And. Therefore, the occurrence of dew condensation can be prevented. The operation will be further described with reference to the control flow diagram of FIG.

ユーザが運転を開始した時、大風量運転モードが選択されていると(S1−Y)、大風量運転モードを実行する(S2)。すなわち前記した主上下風向変更羽根11aをリアガイダ9の延長線上に位置させる。 When the user starts the operation, if the large air volume operation mode is selected (S1-Y), the large air volume operation mode is executed (S2). That is, the main vertical wind direction changing blade 11a described above is positioned on the extension line of the rear guider 9.

次に吸込み風温度センサ23が室内温度Tiを検知し(S3)、更に湿度センサ25が室内湿度Hを検知し(S4)、上記室内温度Tiと室内湿度Hから露点温度Thを算出する(S5)。更に吹出し風温度センサ24が吹出温度Toを検知(S6)し、上記吹出温度Toと前記露点温度Thを比較して吹出温度Toが露点温度Th以上であれば(S7−Y)上記動作を繰り返して大風量運転モードを継続し、吹出温度Toが露点温度Th以下になれば(S7−N)通常風向制御モードに移行していく(S8)。 Next, the suction air temperature sensor 23 detects the room temperature Ti (S3), the humidity sensor 25 detects the room humidity H (S4), and calculates the dew point temperature Th from the room temperature Ti and the room humidity H (S5). ). Further, the blowout air temperature sensor 24 detects the blowout temperature To (S6), compares the blowout temperature To with the dew point temperature Th, and if the blowout temperature To is equal to or higher than the dew point temperature Th (S7-Y), repeats the above operation. The large air volume operation mode is continued, and when the blowout temperature To becomes the dew point temperature Th or less (S7-N), the normal wind direction control mode is started (S8).

このように、吹出温度Toが露点温度Th以上、換言すると、主上下風向変更羽根11aの上下面の空気の温度が露点温度以上であれば大風量運転を行い、大風量運転時の結露の発生を防止している。そして、結露が防止できるので、主上下風向変更羽根11aは中空状に形成する必要がなく、一枚物で、且つ、軽量なものにすることができる。よって、羽根駆動モータ15の能力アップあるいはギアボックスの付設によるトルクアップを必要とせずコストダウンを図ることができる。 In this way, if the outlet temperature To is above the dew point temperature Th, in other words, if the temperature of the air on the upper and lower surfaces of the main vertical wind direction changing blades 11a is above the dew point temperature, a large air volume operation is performed, and dew condensation occurs during the large air volume operation. Is being prevented. Since dew condensation can be prevented, the main vertical wind direction changing blade 11a does not need to be formed in a hollow shape, and can be made into a single piece and lightweight. Therefore, it is possible to reduce the cost without requiring an increase in the capacity of the blade drive motor 15 or an increase in torque due to the attachment of a gearbox.

また、図12はユーザが自動運転モードを選択している場合の制御フロー図を示すが、この自動運転モード時も室内温度と設定温度との差が大きい運転開始時は大風量運転を行い(S2)、迅速かつ効果的な空調を実現できる。 Further, FIG. 12 shows a control flow diagram when the user selects the automatic operation mode. Even in this automatic operation mode, a large air volume operation is performed at the start of operation in which the difference between the room temperature and the set temperature is large ( S2), quick and effective air conditioning can be realized.

すなわち、運転が開始されその運転が自動運転モードであれば(S11−Y)、吸込み風温度センサ23で検知した室内温度Tiと設定温度Tsとを比較し(S12)、その差が所定値以上であると(S12−Y)、大風量運転モードを実行する。そして、吹出温度Toが露点温度Th以下になると(S7−N)、吹出温度が露点温度以上になるようにファンモータ22の回転数を変更制御(S13)してステップ(S12)に戻り、これを繰り返して大風量運転を継続する(S2)。そして、吸込み風温度センサ23で検知した室内温度Tiと設定温度Tsとの差が所定値以下になれば(S12−N)、通常風向制御モードに移行していく(S8)。 That is, if the operation is started and the operation is in the automatic operation mode (S11-Y), the room temperature Ti detected by the suction air temperature sensor 23 and the set temperature Ts are compared (S12), and the difference is equal to or greater than a predetermined value. If (S12-Y), the large air volume operation mode is executed. Then, when the blowing temperature To becomes the dew point temperature Th or less (S7-N), the rotation speed of the fan motor 22 is changed and controlled (S13) so that the blowing temperature becomes the dew point temperature or higher, and the process returns to the step (S12). Is repeated to continue the large air volume operation (S2). Then, when the difference between the indoor temperature Ti detected by the suction air temperature sensor 23 and the set temperature Ts becomes equal to or less than a predetermined value (S12-N), the mode shifts to the normal wind direction control mode (S8).

これにより、前記した如く結露を防止しつつ大風量によって迅速かつ効果的に室内環境を設定温度Tsに近づけ、快適な空調を実現することができる。 As a result, as described above, it is possible to quickly and effectively bring the indoor environment closer to the set temperature Ts by a large air volume while preventing dew condensation, and to realize comfortable air conditioning.

また、本実施の形態では、上記主上下風向変更羽根11aを駆動するリンク機構14は、駆動アーム17の回転中心をX、前記駆動アーム17と上下風向変更羽根アーム18との軸支点をY、前記上下風向変更羽根アーム18の長手方向途中とリンクアーム19との軸支点をZとして、前記XとYとの間の距離をA、前記YとZとの間の距離をBとすると、B=A×(1.2〜1.5)となる構成としてある。 Further, in the present embodiment, the link mechanism 14 for driving the main vertical wind direction changing blade 11a has the rotation center of the drive arm 17 as X, and the shaft fulcrum between the drive arm 17 and the vertical wind direction changing blade arm 18 as Y. Assuming that the axial fulcrum between the vertical wind direction changing blade arm 18 and the link arm 19 in the longitudinal direction is Z, the distance between X and Y is A, and the distance between Y and Z is B, B = A × (1.2 to 1.5).

これにより、上下風向変更羽根アーム18の長手方向途中とリンクアーム19との軸支点Zの移動を円滑なものとすることができ、こじり発生を防止して動作品質を向上させることができる。 As a result, the movement of the shaft fulcrum Z between the vertical direction changing blade arm 18 and the link arm 19 can be made smooth, and the occurrence of prying can be prevented and the operation quality can be improved.

加えて、上記のように構成したことにより、主上下風向変更羽根11aの下向き回動範囲も大きくすることができ、例えば暖房時等に図17に示すように主上下風向変更羽根11aを大きく下向きに回動させた状態で暖房することができる。つまり、主上下風向変更羽根11aによる風向変更巾を広くして空調範囲を拡大することができ、高品質、高性能な空気調和機とすることができる。 In addition, with the above configuration, the downward rotation range of the main vertical wind direction changing blade 11a can also be increased. For example, during heating or the like, the main vertical wind direction changing blade 11a is greatly downward as shown in FIG. It can be heated in a state of being rotated to. That is, the width of the wind direction change by the main vertical wind direction change blades 11a can be widened to expand the air conditioning range, and a high-quality, high-performance air conditioner can be obtained.

以上のように、本実施の形態では、大風量運転時にも結露を防止できるが、この大風量運転モードは冷房運転だけに限らず暖房運転時にも行うようになっている。そして、その動作は冷房時と同じであるので説明は省略する。 As described above, in the present embodiment, dew condensation can be prevented even during the large air volume operation, but this large air volume operation mode is performed not only during the cooling operation but also during the heating operation. Since the operation is the same as that during cooling, the description thereof will be omitted.

(実施の形態2)
次に実施の形態2における空気調和機を説明する。
(Embodiment 2)
Next, the air conditioner according to the second embodiment will be described.

図18は実施の形態2における空気調和機の室内機の吹出口に設けた上下風向変更羽根の軸支構成部分を示す斜視図、図19は同上下風向変更羽根の軸支構成部分の分解斜視図である。 FIG. 18 is a perspective view showing a shaft support component portion of the vertical wind direction changing blade provided at the outlet of the indoor unit of the air conditioner according to the second embodiment, and FIG. 19 is an exploded perspective view of the shaft support component portion of the vertical wind direction changing blade. It is a figure.

本実施の形態2の空気調和機は、前記実施の形態1で示す室内機に実施の形態1で示す主上下風向変更羽根11aとは異なるモータ直結型主上下風向変更羽根(以下、駆動手段直結型主上下風向変更羽根と称す)111aを装着して構成したものである。即ち、羽根駆動モータ15の回転軸15aには駆動アーム17を介することなく駆動手段直結型主上下風向変更羽根111aの上下風向変更羽根アーム118を軸支して前記駆動手段直結型主上下風向変更羽根111aを装着してある。 The air conditioner of the second embodiment is a motor direct connection type main vertical wind direction changing blade (hereinafter, directly connected to the driving means) different from the main vertical wind direction changing blade 11a shown in the first embodiment in the indoor unit shown in the first embodiment. It is configured by mounting 111a (referred to as the mold main vertical wind direction changing blade). That is, the rotary shaft 15a of the blade drive motor 15 is pivotally supported by the vertical wind direction changing blade arm 118 of the main vertical wind direction changing blade 111a directly connected to the driving means without using the driving arm 17, and the main vertical wind direction is changed directly to the driving means. The blade 111a is attached.

これにより、実施の形態1の主上下風向変更羽根11aを駆動手段直結型主上下風向変更羽根111aに切り替えるだけで大風量運転機能を持たない普及型の空気調和機を提供することができ、リアガイダ9の延長線上に主上下風向変更羽根11aを位置させて大風量運転が可能な空気調和機と、大風量運転機能を持たない普及型の空気調和機というタイプの異なる二種類の空気調和機を合理的かつ安価に提供することができる。 As a result, it is possible to provide a popular air conditioner that does not have a large air volume operation function simply by switching the main vertical wind direction changing blade 11a of the first embodiment to the drive means direct connection type main vertical wind direction changing blade 111a.

例えば、本実施の形態では室内機と室外機が分離されている空気調和機で説明したが、これらは一体のものであってもよい。 For example, in the present embodiment, the air conditioner in which the indoor unit and the outdoor unit are separated has been described, but these may be integrated.

また、上下風向変更羽根11は主上下風向変更羽根11a、111aとともに補助上下風向変更羽根11bを備えたものを例示したが、これは主上下風向変更羽根11a、111aのみであってもよいものであり、本発明でいう上下風向変更羽根はこの主上下風向変更羽根11a、111aを示すものである。 Further, the vertical wind direction changing blade 11 is exemplified by having the auxiliary vertical wind direction changing blades 11b together with the main vertical wind direction changing blades 11a and 111a, but this may be only the main vertical wind direction changing blades 11a and 111a. The vertical wind direction changing blades referred to in the present invention indicate the main vertical wind direction changing blades 11a and 111a.

以上のように、本発明にかかる空気調和機は、上下風向変更羽根の結露を防止すると同時に風量低下を抑制して送風性能を向上させ大風量による空調を可能とすることができ、高品質、高性能な空気調和機とすることができる。よって、一般家庭で使用される空気調和機をはじめ様々な空気調和機に広く適用できる。 As described above, the air conditioner according to the present invention can prevent dew condensation on the vertical wind direction changing blades, suppress the decrease in air volume, improve the ventilation performance, and enable air conditioning with a large air volume. It can be a high-performance air conditioner. Therefore, it can be widely applied to various air conditioners including air conditioners used in ordinary households.
