Description

本発明は、車両用空調装置などに設けられ、ブロワーモータの回転軸の両端にツインファン（一対のファン）を取付けた送風機取付構造に関する。   The present invention relates to a blower mounting structure that is provided in a vehicle air conditioner or the like and has twin fans (a pair of fans) mounted on both ends of a rotating shaft of a blower motor.

図４はこの種の従来の送風機取付構造を示す断面図である。図４に示す送風機取付構造は、車室内前部側のインストラクションパネル内に設けられ、ブロワーモータ１０１の回転軸１０２の両端にツインファン（一対のファン）１０３，１０４を有し、これらのツインファン１０３，１０４の回転により吸入口１０５から取入れた空気を吐出口１０６を介して図示しない車室内へ吐出するようになっている。   FIG. 4 is a sectional view showing a conventional blower mounting structure of this type. The blower mounting structure shown in FIG. 4 is provided in an instruction panel on the front side of the passenger compartment, and has twin fans (a pair of fans) 103 and 104 at both ends of the rotating shaft 102 of the blower motor 101. These twin fans The air taken in from the suction port 105 by the rotation of 103 and 104 is discharged through a discharge port 106 into a vehicle compartment (not shown).

この種の従来技術に関連するものとして、例えば特許文献１に記載されている「自動車の空調装置用送風装置」が挙げられる。これは、ブロワーモータの回転軸の両端にファンを装着可能な左右対称形のケーシングを備え、いわゆる右ハンドルの自動車の場合にはブロワーモータの左側（助手席側）にファンを装着し、一方、左ハンドルの自動車の場合にはブロワーモータの右側（助手席側）にファンを装着するようになっている。この従来技術にあっては、ファンの取付位置を変更することによって右ハンドルの自動車及び左ハンドルの自動車の両方に対応することができる。
特開平５−３１９０７３号公報（段落番号００１８〜００２０、図５） As a thing relevant to this kind of prior art, the "air blower for motor vehicle air conditioners" described in patent document 1, for example is mentioned. This includes a symmetrical casing that can be fitted with fans at both ends of the rotating shaft of the blower motor. In the case of a so-called right-hand drive automobile, the fan is attached to the left side (passenger seat side) of the blower motor, In the case of a left-hand drive vehicle, a fan is mounted on the right side (passenger seat side) of the blower motor. In this prior art, it is possible to deal with both right-hand drive vehicles and left-hand drive vehicles by changing the fan mounting position.
JP-A-5-319073 (paragraph numbers 0018 to 0020, FIG. 5)

しかしながら、上述した図４に示す従来技術では、ブロワーモータ１０１の回転軸１０２の両端にツインファン１０３，１０４が取付けられているため、その構造的な特質からブロワーモータ１０１の保守点検や修理などのサービスが困難である。例えば、車室内でのサービス時は、車両用空調装置を収納する図示しないインストルメントパネルを取外したり分解する必要があるため、ブロワーモータ１０１にシングルファンを取付けた場合に比較して、サービス時の付帯作業や作業時間が増えるとともに、インストルメントパネルの形状を規制しなければならない。また、エンジンルーム側からのサービスでは図示しないダッシュパネルを分解する必要があるため、ブロワーモータ１０１にシングルファンを取付けた場合に比較して、サービス時の付帯作業や作業時間が増えるとともに、ダッシュパネル分割部のシール性を損なうおそれがある。   However, in the prior art shown in FIG. 4 described above, the twin fans 103 and 104 are attached to both ends of the rotating shaft 102 of the blower motor 101. Service is difficult. For example, when servicing in the passenger compartment, it is necessary to remove or disassemble an instrument panel (not shown) that houses the vehicle air conditioner. Therefore, compared to when a single fan is attached to the blower motor 101, As incidental work and work time increase, the shape of the instrument panel must be regulated. Further, since the dash panel (not shown) needs to be disassembled for the service from the engine room side, the incidental work and work time at the time of service increase as compared to the case where the single fan is attached to the blower motor 101, and the dash panel There is a risk of impairing the sealing performance of the divided portion.

本発明は、上記のような従来技術を考慮してなされたもので、その目的は、車室内で容易にブロワーモータの保守点検や修理などのサービスを行なうことのできる送風機取付構造を提供することにある。   The present invention has been made in consideration of the above-described conventional technology, and an object of the present invention is to provide a blower mounting structure that can easily perform maintenance and inspection services and repairs of the blower motor in the passenger compartment. It is in.

上記目的を達成するため本発明は、車室内の前部側に支持固定される略筒状のケーシングと、このケーシングに、着脱可能に固定されるブロアモータと、このブロアモータの駆動軸に支持され、前記ケーシングに対し前記ブロアモータの駆動軸方向に挿通可能な一対のファンとからなり、前記ケーシングは、略円筒状に形成される中央部と、この中央部に着脱可能に設けられる端部と、前記ファン及び前記ブロアモータの各径より大きい開口とからなり、前記中央部の内部には、前記ブロアモータを支持する支持部材が着脱可能に設けられるとともに、前記支持部材の車両幅方向の両側に、前記ファンを収納する一対のスクロール室が形成され、前記ケーシングには前記ファンの径より大きく、一方の前記ファン前記ブロアモータ、及び他方の前記ファンを引出し可能な前記開口が形成され、一対の前記ファンと前記支持部材に支持された前記ブロアモータを分解せずに一括して前記ケーシングの前記中央部から引き外し可能であることを特徴とする。 In order to achieve the above object, the present invention is supported by a substantially cylindrical casing supported and fixed to the front side of the vehicle interior, a blower motor detachably fixed to the casing, and a drive shaft of the blower motor. It comprises a pair of fans that can be inserted into the casing in the direction of the drive shaft of the blower motor, and the casing has a central portion formed in a substantially cylindrical shape, an end portion detachably provided at the central portion, The blower motor has openings larger than the diameters of the fan and the blower motor. A support member for supporting the blower motor is detachably provided in the central portion, and the fan is disposed on both sides of the support member in the vehicle width direction. a pair of scroll chambers formed for accommodating said the casing larger than the diameter of the fan, one of the fan the blower motor, and the other And characterized in that the fan is the aperture capable drawn out is formed, can be removed off from the central portion of the casing at once without decomposing the supported the blower motor to the support member and a pair of said fan To do.

このように構成した本発明では、ファンのうちの少なくとも一方をケーシングに対して車両幅方向へ挿通することによりケーシングから取外した後、ブロアモータをケーシングから車両幅方向へ引き出す。これによって、インストルメントパネルの取外しや分解作業を要せずに、車室内で容易にブロワーモータの保守点検や修理などのサービスを行なうことができる。また、エンジンルーム側からのサービスを行なわないので、車室内の前部側のダッシュパネルを分解する必要もなくて済む。   In this invention comprised in this way, after removing from a casing by inserting at least one of a fan with respect to a casing in a vehicle width direction, a blower motor is pulled out from a casing in a vehicle width direction. As a result, it is possible to easily perform services such as maintenance and repair of the blower motor in the vehicle interior without requiring removal or disassembly work of the instrument panel. Further, since no service is provided from the engine room side, it is not necessary to disassemble the dash panel on the front side in the vehicle compartment.

本発明では、車室内前部側のインストルメントパネルの取外しや分解作業を要せずに、車室内で容易にブロワーモータの保守点検や修理などのサービスを行なうことができ、また、エンジンルーム側からのサービスのためにダッシュパネルを分解する必要もない。したがって、サービス時の付帯作業や作業時間を削減できるとともに、インストルメントパネルの形状規制に伴う設計変更などの手間を省くことができ、かつ、ダッシュパネル分割部のシール性を向上できるという効果がある。   In the present invention, it is possible to easily perform a service such as a maintenance inspection and repair of the blower motor in the vehicle interior without requiring removal or disassembly work of the instrument panel on the front side of the vehicle interior. There is also no need to disassemble the dash panel for service from. Therefore, it is possible to reduce ancillary work and work time at the time of service, to save time and troubles such as a design change accompanying the shape regulation of the instrument panel, and to improve the sealing performance of the dash panel dividing portion. .
