The shaft is fixed to the shaft opening 12a via a rubber member (not shown) that is fitted into the shaft opening 12a (see FIG. 3). .

[0028] As shown in FIG. 4, the casing 11 and the motor cover 12 are arranged such that the axis P of the rotating shaft 8 passes through them. The casing 11 and the motor cover 12 are divided at a dividing line L. It is divided into two by a plane that passes through the axis P of 8 and is parallel to the axis P.

[0029] As a more preferable configuration, in this embodiment, as shown in FIG. 5 and FIG. The front surface having the opening 53 has a flat surface H that is continuous in the left-right direction, which is also the longitudinal direction. The left and right surfaces corresponding to both ends 10a in the front-rear direction have flat surfaces H that are continuous in the front-rear direction. The cabinet 10 has an intake opening 52 on the top surface and an exhaust opening 53 on the front surface. The cabinet 10 has a rear surface 10c that forms a rear wall corresponding to the flat surface portion H that is continuous in the left-right direction. Furthermore, the cabinet 10 has a front surface 10c and a rear surface 10c, and also has a left-right surface 10d in the longitudinal direction. The left and right surfaces also have flat surfaces H that continue in the front-rear direction. The flat portions H on the left and right sides are integrally provided with fixing portions 30 for fixing the bearing portions 20 of the fan connector 2. It is made by molding.

[0030] (Attaching and detaching fan connector 2) Next, referring to FIG. 1, FIG. 2 and FIG. 3, the fan connector 2 is attached to and detached from the cabinet 10. First, the removal of the fan connector 2 will be described.

[0031] When removing the fan connector 2, first remove the four cases located on the underside of the blower 1. The lower part of the motor cover 12-2, the lower part of the motor cover 12-2, and the outer casing part 13, etc. (See Figure 1) is then removed. This brings the fan connector 2 into a detachable state as shown in Figure 2. In addition, a part 13a of the outer shell part 13 is integrally formed with the lower casing 11-2. Therefore, it can be removed by removing the lower casing 11-2.

[0032] Next, at both ends of the fan connector 2, the bearing portion 20 and the fixing portion 3 on the cabinet 10 side are The screws (not shown) that connect the bearing portion 20 and the fixed portion 30 are removed. However, since it has a temporary fixing structure, the screw fastening on both sides of the fan connector 2 can be released. Even if the fan connector 2 is pulled out, it will not fall under its own weight, and the operator can hold it with his / her hands. After removing the screws, release the temporary fastening and pull out the bearing part 20 from the fixed part 30. .

[0033] On the other hand, when mounting, the both ends of the fan connector 2 are grasped and the bearing portion 20 is fixed to the fixing portion 30. Then, the bearing portion 20 is inserted into the fixing portion 20 and temporarily fixed using the previously described temporary fixing structure. Then, the four casing lowers 11-2, Attach the bottom side parts such as the motor cover 12-2 and the outer casing part 13 (see Figure 1). Since the part 13a of the outer shell part 13 is integrally formed with the lower casing 11-2, It can be installed together by attaching the lower casing 11-2.

[0034] (effect) As described above, in the blower 1, the plurality of casings 11-1 and the motor cover The upper part 12-1 is molded integrally with the cabinet 10. This reduces the number of parts, Attach the casing top 11-1 and the motor cover top 12-1 to the cabinet 10. This eliminates the need for a process, simplifying the assembly process.

[0035] In addition to the effect of reducing the number of parts, the casing 11-1 and the motor By integrally molding the upper bar 12-1 with the cabinet 10, the rigidity (strength) of the cabinet 10 is increased. This can prevent the cabinet 10 from being deformed, such as twisted or warped. This makes it difficult for the shaft alignment to occur, and the shaft alignment during assembly is maintained for a long period of time, preventing shaft misalignment in the rotating shaft. The generation of vibrations and noise can be suppressed and the blower fan can rotate stably.

[0036] Moreover, the casing 11 and a part of the motor cover 12 are built into the cabinet 10. Then, the remaining parts of the casing 11 and the motor cover 12 are fitted together to form the casing. The housing 11 and the motor cover 12 are completed. Therefore, the cabinet does not require separate parts. The casing 11 and the motor cover 12 are attached in a manner that does not cause misalignment. This makes alignment easy.

[0037] Furthermore, in this embodiment, the bearing portion 20 attached to the rotating shaft 8 of the fan connector 2 is The fixing part 30 to which the cabinet 10 is attached is also molded integrally with the cabinet 10. There is no misalignment between the cabinet 10 and the cabinet 30. As a result, it is possible to prevent the casing 11, the motor cover 12, and the fixing portion 30 from being misaligned. The axis of the rotation shaft 8 of the fan connector 2 and the positions of the components are not misaligned, and alignment is easy. It can be easily constructed.

[0038] In the above configuration, the casing 11 and the motor are separated at a dividing line L through which the axis of the rotating shaft 8 passes. Therefore, the casing upper part 11-1 and the motor cover 12 are divided. Even if the upper 12-1 is built in, the cabinet 10 is removed from the mold during production. There is no problem in that it becomes difficult to

[0039] As a more preferable configuration, in this embodiment, the front surface having the blow-out opening 53 is provided with: The plate has a flat surface H that is continuous in the left-right direction, which is also the longitudinal direction, and corresponds to both ends 10a in the longitudinal direction. The left and right walls of the rear wall are configured to have flat surfaces H that are continuous in the front-rear direction. The rigidity of the cabinet 10 is effectively improved compared to a flat cabinet having a rear surface 10c that is mainly made up of a flat plate. This effectively improves the strength of the material, resulting in a robust structure that is almost free from twisting or warping.

[0040] In addition, the casing 11 and the motor cover 12 are divided in the vertical direction, so that the blower The fan connector 2 can be attached and detached from the bottom of the fan unit 1. Since the space below the wind device is open, it can be attached and detached from below. There is no need to work above the ceiling, and it can be removed even if there is not enough space between the ceiling and the sides. It will be possible to wear it.
