Description

本発明は、風向を変更するルーバを備えた空気調和装置の室内機に関するものである。 The present invention relates to an indoor unit of an air conditioner provided with a louver that changes the wind direction.

空気調和装置の室内機には、空調後の空気の向きを変更するためのルーバが設けられている。ルーバは、室内機の吹出口に横方向に所定間隔を有して複数並べられている（例えば特許文献１）。 The indoor unit of the air conditioner is provided with a louver for changing the direction of air after air conditioning. A plurality of louvers are arranged at a predetermined interval in the lateral direction at the outlet of the indoor unit (for example, Patent Document 1).

特開平１１−１１８１８６号公報Japanese Unexamined Patent Publication No. 11-118186

複数のルーバを同期して回動させるために、各ルーバが回動自在に取り付けられた連結部材を用いる。連結部材は、棒状とされており、一端にリンク部材が取り付けられている。リンク部材をモータによって揺動させることで、連結部材を長手方向に往復動させて各ルーバを回動させて風向制御する。 In order to rotate a plurality of louvers synchronously, a connecting member to which each louver is rotatably attached is used. The connecting member has a rod shape, and a link member is attached to one end thereof. By swinging the link member with a motor, the connecting member is reciprocated in the longitudinal direction to rotate each louver and control the wind direction.

しかし、連結部材は、各ルーバを連結するため長尺となり寸法管理が難しい。また、連結部材の基準位置が正確に決められていないと、各ルーバを整列して正面を向かせることができず、見栄えが悪くなるという問題がある。 However, since the connecting member connects each louver, it is long and difficult to control the dimensions. Further, if the reference position of the connecting member is not accurately determined, it is not possible to align the louvers and face the front surface, which causes a problem that the appearance is deteriorated.

本発明は、このような事情に鑑みてなされたものであって、複数のルーバの位置決めを正確に行うことができる空気調和装置の室内機を提供することを目的とする。 The present invention has been made in view of such circumstances, and an object of the present invention is to provide an indoor unit of an air conditioner capable of accurately positioning a plurality of louvers.

上記課題を解決するために、本発明の空気調和装置の室内機は以下の手段を採用する。
すなわち、本発明にかかる空気調和装置の室内機は、一方向に所定間隔を有して並べられ、風向を変更する複数のルーバと、前記一方向に延在するとともに各前記ルーバが回動自在に取り付けられ、長手方向に往復動する連結部材と、前記連結部材に対して回動自在に取り付けられたリンク部材と、該リンク部材を揺動させるモータと、該モータを本体に対して固定するモータブラケットと、該モータブラケットに設けられ、前記連結部材の先端に当接するストッパとを備えていることを特徴とする。 In order to solve the above problems, the indoor unit of the air conditioner of the present invention employs the following means.
That is, the indoor units of the air conditioner according to the present invention are arranged with a predetermined interval in one direction, and have a plurality of louvers that change the wind direction, and the louvers extend in one direction and each of the louvers is rotatable. A connecting member that is attached to and reciprocates in the longitudinal direction, a link member that is rotatably attached to the connecting member, a motor that swings the link member, and the motor is fixed to the main body. It is characterized by including a motor bracket and a stopper provided on the motor bracket and in contact with the tip of the connecting member.

モータによってリンク部材が揺動されると、リンク部材が取り付けられた連結部材が移動する。連結部材が移動すると、連結部材に取り付けられた各ルーバが回動し、風向が変更される。
モータを本体に固定するモータブラケットには、連結部材に当接するストッパが設けられている。連結部材はストッパに当接すると移動が規制され、各ルーバの位置決めが行われる。このように、モータを取り付けたモータブラケットに設けたストッパによって位置が決定されるので、ケーシング等の他の部材のようにモータを取り付けたモータブラケットとは異なる部材にストッパを設けた場合に比べて正確に各ルーバの位置決めを行うことができる。 When the link member is swung by the motor, the connecting member to which the link member is attached moves. When the connecting member moves, each louver attached to the connecting member rotates, and the wind direction is changed.
The motor bracket that fixes the motor to the main body is provided with a stopper that comes into contact with the connecting member. When the connecting member comes into contact with the stopper, the movement is restricted and each louver is positioned. In this way, since the position is determined by the stopper provided on the motor bracket to which the motor is attached, the position is determined as compared with the case where the stopper is provided on a member different from the motor bracket to which the motor is attached, such as other members such as a casing. Each louver can be positioned accurately.

さらに、本発明の空気調和装置の室内機では、前記ストッパは、前記連結部材に対して正対する位置で当接することを特徴とする。 Further, the indoor unit of the air conditioner of the present invention is characterized in that the stopper abuts at a position facing the connecting member.

連結部材に対して正対する位置でストッパが当接するので、連結部材とストッパが当接した後に連結部材がずれることを抑制できる。これにより、より正確なルーバの位置決めを行うことができる。 Since the stopper comes into contact with the connecting member at a position facing the connecting member, it is possible to prevent the connecting member from shifting after the connecting member and the stopper come into contact with each other. As a result, more accurate louver positioning can be performed.

さらに、本発明の空気調和装置の室内機では、前記モータを制御する制御部を備え、前記制御部は、前記ストッパに前記連結部材が当接した位置を基準位置として設定することを特徴とする。 Further, the indoor unit of the air conditioner of the present invention includes a control unit that controls the motor, and the control unit sets a position where the connecting member abuts on the stopper as a reference position. ..

ストッパが連結部材に当接した位置を、基準位置として制御部が設定することによって、各ルーバの基準位置が正確に決定される。これにより、各ルーバの回動角度を所望位置に制御することができる。 The reference position of each louver is accurately determined by setting the position where the stopper comes into contact with the connecting member as the reference position. Thereby, the rotation angle of each louver can be controlled to a desired position.

モータを取り付けたモータブラケットに設けたストッパによって位置が決定されるので、複数のルーバの位置決めを正確に行うことができる。 Since the position is determined by the stopper provided on the motor bracket to which the motor is attached, the positioning of a plurality of louvers can be performed accurately.

以下に、本発明にかかる一実施形態について、図面を参照して説明する。
図１には、空気調和装置の室内機１の外観が示されている。室内機１は、壁掛形とされており、上方から室内空気を吸い込み、下方の吹出口から室内へと空調後の空気を吹き出す。室内機１は、図示しない室外機と接続されており、室外機にて圧縮された冷媒の供給を受け、室内機１の内部に設けられた室内熱交換器によって室内の空気を所定温度に調整する。 Hereinafter, an embodiment according to the present invention will be described with reference to the drawings.
FIG. 1 shows the appearance of the indoor unit 1 of the air conditioner. The indoor unit 1 has a wall-mounted type, sucks indoor air from above, and blows air after air conditioning into the room from a lower air outlet. The indoor unit 1 is connected to an outdoor unit (not shown), receives the supply of the refrigerant compressed by the outdoor unit, and adjusts the indoor air to a predetermined temperature by the indoor heat exchanger provided inside the indoor unit 1. do.

図２には、室内機１の内部が示されている。同図に示されているように、室内の壁面に固定されるベースプレート３に対して、室内熱交換器５が取り付けられている。室内熱交換器５の下方には、室内機１の幅方向に設けられた吹出口７が形成されている。吹出口７には、幅方向（一方向）に所定間隔を有して複数のルーバ９が設けられている。各ルーバ９は、樹脂製とされた板状体とされている。各ルーバ９は、室内機１の本体側に設けられた軸受部１１に対して回動自在に取り付けられている。各ルーバ９には、取付ピン９ａ（図３（ａ））参照が設けられており、この取付ピン９ａが連結部材１３に対して回動自在に取り付けられている。 FIG. 2 shows the inside of the indoor unit 1. As shown in the figure, the indoor heat exchanger 5 is attached to the base plate 3 fixed to the wall surface of the room. Below the indoor heat exchanger 5, an air outlet 7 provided in the width direction of the indoor unit 1 is formed. The air outlet 7 is provided with a plurality of louvers 9 at predetermined intervals in the width direction (one direction). Each louver 9 is a plate-shaped body made of resin. Each louver 9 is rotatably attached to a bearing portion 11 provided on the main body side of the indoor unit 1. Each louver 9 is provided with a reference to a mounting pin 9a (FIG. 3A), and the mounting pin 9a is rotatably attached to the connecting member 13.

連結部材１３は、樹脂製とされ、室内機１の幅方向に延在する棒状とされている。連結部材の一端である左端は、モータブラケット１５側に位置するように配置されている。 The connecting member 13 is made of resin and has a rod shape extending in the width direction of the indoor unit 1. The left end, which is one end of the connecting member, is arranged so as to be located on the motor bracket 15 side.

モータブラケット１５は、室内機１の本体に固定されており、ルーバ９を駆動するためのモータを収容する。 The motor bracket 15 is fixed to the main body of the indoor unit 1 and houses a motor for driving the louver 9.

図３には、連結部材１３とモータブラケット１５の周囲の拡大図が示されている。連結部材１３の左端には、リンク部材１７の一端が回動自在に取り付けられている。リンク部材１７の他端は、モータ軸１９に取り付けられている。したがって、モータによってモータ軸１９が回動すると、リンク部材１７が揺動し、これによって連結部材１３が略長手方向に往復動する。この連結部材１３の往復動によって、各ルーバ９の回動角度が変更される。モータ軸１９の回動角度は、図示しない制御部へと送られる。 FIG. 3 shows an enlarged view of the periphery of the connecting member 13 and the motor bracket 15. One end of the link member 17 is rotatably attached to the left end of the connecting member 13. The other end of the link member 17 is attached to the motor shaft 19. Therefore, when the motor shaft 19 is rotated by the motor, the link member 17 swings, whereby the connecting member 13 reciprocates in the substantially longitudinal direction. The reciprocating movement of the connecting member 13 changes the rotation angle of each louver 9. The rotation angle of the motor shaft 19 is sent to a control unit (not shown).

モータブラケット１５には、ストッパ１６が固定されている。ストッパ１６は、図４に示すように、連結部材１３の先端１３ａに当接することによって、連結部材１３の移動を規制する。
図３（ｂ）及び図４（ｂ）から分かるように、連結部材１３の先端１３ａの当接面１３ｂとストッパ１６の当接面１６ａとは面接触するようになっている。すなわち、ストッパ１６の当接面１６ａは、連結部材１３の当接面１３ｂに対して正対するように設定されている。 A stopper 16 is fixed to the motor bracket 15. As shown in FIG. 4, the stopper 16 regulates the movement of the connecting member 13 by abutting on the tip 13a of the connecting member 13.
As can be seen from FIGS. 3 (b) and 4 (b), the contact surface 13b of the tip 13a of the connecting member 13 and the contact surface 16a of the stopper 16 are in surface contact with each other. That is, the contact surface 16a of the stopper 16 is set to face the contact surface 13b of the connecting member 13.

制御部は、ストッパ１６に連結部材１３の先端１３ａが当接した位置を基準位置として設定する。そして、この基準位置に基づいて、モータ軸１９の回動角度を制御し、各ルーバ９の位置制御を行う。
制御部は、例えば、ＣＰＵ（Central Processing Unit）、ＲＡＭ（Random Access Memory）、ＲＯＭ（Read Only Memory）、及びコンピュータ読み取り可能な記憶媒体等から構成されている。そして、各種機能を実現するための一連の処理は、一例として、プログラムの形式で記憶媒体等に記憶されており、このプログラムをＣＰＵがＲＡＭ等に読み出して、情報の加工・演算処理を実行することにより、各種機能が実現される。なお、プログラムは、ＲＯＭやその他の記憶媒体に予めインストールしておく形態や、コンピュータ読み取り可能な記憶媒体に記憶された状態で提供される形態、有線又は無線による通信手段を介して配信される形態等が適用されてもよい。コンピュータ読み取り可能な記憶媒体とは、磁気ディスク、光磁気ディスク、ＣＤ−ＲＯＭ、ＤＶＤ−ＲＯＭ、半導体メモリ等である。 The control unit sets a position where the tip 13a of the connecting member 13 abuts on the stopper 16 as a reference position. Then, based on this reference position, the rotation angle of the motor shaft 19 is controlled, and the position of each louver 9 is controlled.
The control unit is composed of, for example, a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), a computer-readable storage medium, and the like. Then, as an example, a series of processes for realizing various functions are stored in a storage medium or the like in the form of a program, and the CPU reads this program into a RAM or the like to execute information processing / arithmetic processing. As a result, various functions are realized. The program is installed in a ROM or other storage medium in advance, is provided in a state of being stored in a computer-readable storage medium, or is distributed via a wired or wireless communication means. Etc. may be applied. Computer-readable storage media include magnetic disks, magneto-optical disks, CD-ROMs, DVD-ROMs, semiconductor memories, and the like.

各ルーバ９の基準位置の位置決めは、以下のように行う。
先ず、制御部の指令によってモータを駆動しモータ軸１９の回動によってリンク部材１７を揺動させる。リンク部材１７の揺動によって連結部材１３の先端１３ａがストッパ１６側に移動し、連結部材１３の当接面１３ｂがストッパ１６の当接面１６ａに面接触する。これにより、連結部材１３の移動が規制され、この位置を制御部は基準位置として設定する。この基準位置を基準として、制御部はモータ軸１９を回動し、ルーバ９の風向角度を制御する。 The reference position of each louver 9 is positioned as follows.
First, the motor is driven by a command from the control unit, and the link member 17 is swung by the rotation of the motor shaft 19. The swing of the link member 17 causes the tip 13a of the connecting member 13 to move toward the stopper 16, and the contact surface 13b of the connecting member 13 comes into surface contact with the contact surface 16a of the stopper 16. As a result, the movement of the connecting member 13 is restricted, and the control unit sets this position as a reference position. The control unit rotates the motor shaft 19 with reference to this reference position, and controls the wind direction angle of the louver 9.

上述の室内機１によれば、以下の作用効果を奏する。
モータを室内機１の本体に固定するモータブラケット１５には、連結部材１３に当接するストッパ１６が設けられている。連結部材１３はストッパ１６に当接すると移動が規制され、各ルーバ９の位置決めが行われる。このように、モータを取り付けたモータブラケット１５に設けたストッパ１６によって位置が決定されるので、ケーシング等の他の部材のようにモータを取り付けたモータブラケット１５とは異なる部材にストッパ１６を設けた場合に比べて正確に各ルーバ９の位置決めを行うことができる。 According to the indoor unit 1 described above, the following effects are exhibited.
The motor bracket 15 that fixes the motor to the main body of the indoor unit 1 is provided with a stopper 16 that comes into contact with the connecting member 13. When the connecting member 13 comes into contact with the stopper 16, the movement of the connecting member 13 is restricted, and each louver 9 is positioned. In this way, since the position is determined by the stopper 16 provided on the motor bracket 15 to which the motor is attached, the stopper 16 is provided on a member different from the motor bracket 15 to which the motor is attached, such as other members such as a casing. It is possible to position each louver 9 more accurately than in the case.

連結部材１３に対して正対する位置でストッパ１６が当接して面接触するので、大きな摩擦力が働くことで、連結部材１３とストッパ１６が当接した後に連結部材１３がずれることを抑制できる。これにより、より正確なルーバ９の位置決めを行うことができる。 Since the stopper 16 comes into contact with the connecting member 13 at a position facing the connecting member 13 and comes into surface contact with the connecting member 13, it is possible to prevent the connecting member 13 from shifting after the connecting member 13 and the stopper 16 come into contact with each other due to a large frictional force. As a result, more accurate positioning of the louver 9 can be performed.

ストッパ１６が連結部材１３に当接した位置を、基準位置として制御部が設定することによって、各ルーバ９の基準位置が正確に決定される。これにより、各ルーバ９の回動角度を所望位置に制御することができる。 The reference position of each louver 9 is accurately determined by setting the position where the stopper 16 comes into contact with the connecting member 13 as the reference position. Thereby, the rotation angle of each louver 9 can be controlled to a desired position.
