Abstract

(57) [Summary] [Purpose] To improve workability and workability in mounting the blower motor to the fan plate in the blower section of the air conditioner. [Structure] A mounting hole for mounting a sirocco-shaped fan fixing portion in a fan plate is formed by cutting and raising, and both the shafts of the blower motor are rotatably supported by the cutting and raising portion. [Effect] The workability and workability can be improved without requiring a special support mechanism for the blower motor.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an air conditioner, and more particularly to a support for a blower motor thereof.

[0002]

[Prior Art]

 FIG. 2 is a vertical sectional view of a conventional general air conditioner, and FIG. 3 is an exploded perspective view of a blower part thereof. As shown in FIG. 2, this air conditioner has a box-like appearance, and a heat exchanger 2 for exchanging heat between the air to be conditioned and the refrigerant is provided at the center of the box 1. An air blower unit 3 for blowing air to be conditioned to the heat exchanger 2 is provided at the upper part of each, and is fixed to the box body 1 by screwing. As shown in FIG. 3, the blower unit 3 includes a blower motor 10, a movable portion 4a of a sirocco-shaped fan fixed to both shafts of the blower motor 10, and a crimp band inserted into both shafts of the blower motor 10. 6, a rubber bush 5 fixed by crimping and fixing, a fan plate 9 to which a sirocco fan fixing portion 4b is directly fixed via a mounting hole 9a, and a motor mounting foot supported on the fan plate 9 via a motor frame 8. It is composed of 7.

[0003]

[Problems to be solved by the device]

 The conventional air conditioner is configured as described above, and the blower motor 10 is mounted on the fan plate 9 via the motor mounting legs 7 and the motor frame 8. Therefore, the support mechanism of the blower motor 10 becomes complicated, and screwing work in a narrow space is required, resulting in poor workability and workability.

The present invention has been made to solve the above problems, and provides an air conditioner capable of fixing a fan motor to a fan plate with good workability and workability. The purpose is to

[0005]

[Means for Solving the Problems]

 In the air conditioner according to the present invention, the mounting holes of the sirocco type fan fixing part of the fan plate of the blower part are formed by cutting and raising, and the cutting and raising parts support both shafts of the blower motor. is there.

[0006]

[Action]

 In this invention, a mounting hole for mounting the sirocco-shaped fan fixing portion in the fan plate is formed by cutting and raising, and both of the shafts of the blower motor are directly supported by the cutting and raising portion, and the motor mounting foot 7 and the motor frame. 8 is no longer needed.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of a blower section of an air conditioner according to this embodiment, and 11 is a fan plate. The fan plate 11 has a mounting hole 11a for mounting the fixing portion 4b of the sirocco fan formed by cutting and raising, the insertion portion 4c of the fixing portion 4b is inserted into the mounting hole 11a, and is screwed to the fan plate 11 by the flange portion 4d. To be done. On the other hand, the rubber bushes 5 inserted into both shafts of the blower motor 10 are delivered to the recess 11c formed in the cut-and-raised portion 11b of the fan plate 11, and the locking portion formed outside the cut-and-raised portion 11b. The rubber bush 5 is fixedly supported by locking the crimping band 6 having a split structure to 11d and integrally tightening it. Therefore, the blower motor 10 having both shafts inserted in the rubber bush 5 is also rotatably supported. ..

[0008]

[Effect of the device]

 As described above, according to the present invention, since the blower motor is rotatably supported by the cut-and-raised portion of the fan plate, a special support mechanism for the blower motor is not required, and the number of parts and working time are reduced. , The effect of improving the coaxiality of the blower motor and the sirocco type fan, and therefore the reliability of the blower unit as a whole can be improved.
