Description

空気調和機Air conditioner
　本発明は、空気調和機の室内機におけるファンモーターの着脱構造、および、台枠のコーナー部材の構成に関するものである。 The present invention relates to a fan motor attaching / detaching structure in an indoor unit of an air conditioner, and a configuration of a corner member of a frame.
　従来の空気調和機の室内機は、図７Ａに示すように、台枠１０２の下部の左右のコーナー部に着脱自在なコーナー部材１０６を備えている。このコーナー部材１０６により、室内機の取付け、取外し工事やサービス工事の時の作業の容易化を図っている。また、室内機内に設けられたファンモーター１０４をサービス工事などで取り外すときには、図７Ｂに示すように、室内機の一側部に設けられた電源板１０８を取り外し、当該電源板１０８が収納されていたスペースを利用してファンモーター１０４を取り外すことができる。 The conventional indoor unit of an air conditioner includes a detachable corner member 106 at the left and right corner portions of the lower part of the frame 102 as shown in FIG. 7A. The corner member 106 facilitates work at the time of indoor unit installation, removal work, and service work. When the fan motor 104 provided in the indoor unit is removed for service work or the like, as shown in FIG. 7B, the power supply plate 108 provided on one side of the indoor unit is removed and the power supply plate 108 is accommodated. The fan motor 104 can be removed using the remaining space.
　また、例えば、特許文献１（特開２００２－７１１６２号公報）には、台枠のコーナー部が上下２部品から成る着脱自在なコーナーカバーを備える室内機が開示されている。 Further, for example, Patent Document 1 (Japanese Patent Laid-Open No. 2002-71162) discloses an indoor unit in which a corner portion of a frame is provided with a detachable corner cover having two upper and lower parts.
特開２００２－７１１６２号公報JP 2002-71162 A
　前記従来の空気調和機において、熱交換の効率を向上させるためには、熱交換器１０３の全長（水平方向の長さ）を長くすることが有効である。しかしながら、熱交換器１０３の全長を長くすると、室内機の一側部に設けたファンモーター１０４をサービス工事などで取り外すときに、台枠１０２の側壁が干渉して、ファンモーター１０４の取り外しができないという課題がある。 In the conventional air conditioner, in order to improve the efficiency of heat exchange, it is effective to increase the total length (horizontal length) of the heat exchanger 103. However, if the overall length of the heat exchanger 103 is increased, when the fan motor 104 provided on one side of the indoor unit is removed for service work or the like, the side wall of the underframe 102 interferes and the fan motor 104 cannot be removed. There is a problem.
　この課題を解決する方法として、特許文献１に記載されているように、台枠のコーナー部を上下２部品からなるコーナーカバーで構成することが考えられる。しかしながら、この構成では、例えば、室内機の配送・運搬時において、室内機に外力が加わったり、室内機が落下したりしたときに、コーナーカバーが内枠から外れ易いという課題がある。 As a method for solving this problem, as described in Patent Document 1, it is conceivable to form the corner portion of the underframe with a corner cover composed of two upper and lower parts. However, with this configuration, for example, when delivering or transporting the indoor unit, there is a problem that the corner cover is easily detached from the inner frame when an external force is applied to the indoor unit or the indoor unit falls.
　本発明の目的は、前記従来の課題を解決することにあって、熱交換器の全長を長くしてもファンモーターの取り外しを可能にするとともに、コーナー部材が台枠から外れ難くすることができる空気調和機を提供することにある。 An object of the present invention is to solve the above-described conventional problem, and even if the total length of the heat exchanger is increased, the fan motor can be removed and the corner member can be prevented from being detached from the frame. It is to provide an air conditioner.
　前記課題を解決するため、本発明の空気調和機は、室内機に、熱交換器と、前記熱交換器を保持するとともに送風通路を構成する台枠と、前記熱交換器と前記台枠とで構成された空間に設けられたファンと、前記ファンを回転駆動させるファンモーターとを備え、前記台枠の下部のコーナー部が着脱自在なコーナー部材で構成された空気調和機において、前記コーナー部材と前記台枠との接合部を前記ファンモーターの上端よりも上方の位置に設けるとともに、前記コーナー部材の側壁内面に前記台枠と係合する係合部を設けた構成を有する。 In order to solve the above-described problem, an air conditioner according to the present invention includes, in an indoor unit, a heat exchanger, a frame that holds the heat exchanger and forms a ventilation passage, and the heat exchanger and the frame. In the air conditioner comprising a fan provided in a space constituted by a fan motor for rotating and driving the fan, and the corner portion at the bottom of the underframe is a detachable corner member, the corner member And the base frame are provided at a position above the upper end of the fan motor, and an engaging portion that engages with the base frame is provided on the inner surface of the side wall of the corner member.
　本発明に係る空気調和機によれば、コーナー部材と台枠との接合部をファンモーターの上端よりも上方の位置に設けている。すなわち、コーナー部材の側壁（縦側壁部）の長さを長くして、コーナー部材を取り外した際、ファンモーターが外部に露出するようにしている。これにより、熱交換器の全長を長くしてもファンモーターの取り外しが可能となり、サービス工事の時などにおいてファンモーターの着脱（取外し、取付け）を容易に行うことができる。 According to the air conditioner according to the present invention, the joint portion between the corner member and the frame is provided at a position above the upper end of the fan motor. That is, the length of the side wall (vertical side wall) of the corner member is increased so that the fan motor is exposed to the outside when the corner member is removed. As a result, the fan motor can be removed even when the overall length of the heat exchanger is increased, and the fan motor can be easily attached and detached (removed and attached) during service construction.
　ここで、従来の室内機に比べて、コーナー部材の側壁の長さを長くした場合、当該側壁が湾曲し易くなる。これに対して、本発明に係る空気調和機によれば、コーナー部材の側壁内面に係合部を設けて、当該係合部によりコーナー部材と台枠とが係合するように構成しているので、コーナー部材の側壁の湾曲を抑えて、コーナー部材が台枠から外れ難くすることができる。 Here, when the length of the side wall of the corner member is increased as compared with the conventional indoor unit, the side wall is likely to be bent. On the other hand, according to the air conditioner according to the present invention, the engaging portion is provided on the inner surface of the side wall of the corner member, and the corner member and the frame are engaged by the engaging portion. Therefore, the curvature of the side wall of the corner member can be suppressed and the corner member can be made difficult to come off from the frame.
