DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail as examples based on the attached drawings.
FIG. 1 is a cross-sectional view showing an air conditioner according to the present invention, and FIG. 2 is an exploded perspective view showing a fixture for a fan motor. FIG. 3 is a cross-sectional view showing a procedure when the fan motor is removed.
As shown in FIG. 1, the air conditioner according to the present invention includes a base 1 having a front surface opened, a front panel having a rear surface opened attached to the front surface of the base 1, and a suction port. The main body is composed of a suction grill provided detachably. A front suction port 2 formed of a plurality of horizontal rails is provided on the front surface of the main body, an upper surface suction port 3 similarly formed of a plurality of horizontal rails is provided on the upper surface, and a blower outlet 4 is provided on the lower portion of the front surface. Is provided. In the air passage connecting the front suction port 2 and the upper suction port 3 and the blower outlet 4, a vertical portion 5 a and a rear inclined portion 5 b bent at the upper end of the vertical portion 5 a and inclined backward. A heat exchanger 5 comprising a front inclined portion 5c bent forward at the upper end of the rear inclined portion 5b is provided, and heat exchange is performed by the exchanger 5 on the downstream side of the heat exchanger 5. A blower fan 6 composed of a cross flow fan that sends out the blown air into the room from the blower outlet 4 and a fan motor 7 that is connected to and drives the blower fan 6 are provided on one side of the main body. The counter drive shaft side of the motor 7 is mounted on the rear surface of the fan motor 7, the base 9, the sliding member 10 that is supported slidably on the base 9, and the sliding member 10. It is attached to the base 1 with a fixture 11 that holds the vibration isolator so as to hold it. It has become way.
[0009]
The fixing device for the fan motor 7 is configured as shown in FIG. The drive shaft side of the fan motor 7 has a base 12a erected on the base 1 and a bottomed cylindrical cap that is formed on the base 12a and is fixed so as to cover the outer periphery of the fan motor 7. The bottom portion is formed with an insertion hole through which the drive shaft of the fan motor 7 is inserted. The fan motor 7 has a non-driving shaft side that is erected on the base 1 and has an upper end surface that is formed in an arc shape that is recessed inward, and a sliding groove 9a that is formed on the upper end surface of the arc shape. A base 9 and an arcuate portion 10a bulging outward corresponding to the sliding groove 9a are formed on the outer periphery, and the inner periphery does not interfere with the cylindrical vibration isolating member 7a mounted on the bearing of the fan motor 7 As described above, the sliding member 10 having the corresponding arc-shaped notch 10b and the vibration-proof member 7a are inserted therethrough, and the cylindrical attached portion 11a attached thereto, and the attached portion 11a. A joint 11b that extends from the upper and lower ends of the joint and is joined to the sliding member 10; a rib 11c that is laid between the joint 11b and the pressing part 11a; and upper and lower screws that are formed in the rib 11c. The fixing plate 11 is provided with an insertion hole 11d. A screw hole 7b is provided on the outer peripheral surface of the fan motor 7 on the counter drive shaft side so as to face the screw insertion hole 11d.
[0010]
Next, a procedure for mounting and removing the fan motor 7 from the fixing device will be described. When mounting, the drive shaft side of the fan motor 7 is first inserted into the cap portion 12b and fixed. Subsequently, the arcuate portion 10a of the sliding member 10 is inserted from the end of the sliding groove 9a of the base 9, and the sliding groove 10 is pressed against the fan motor 7 while pressing one side surface of the sliding member 10. The inside of 9a is slid and rotated to a predetermined position. Next, the adherend portion 11a of the fixed plate 11 is inserted and attached to the vibration isolating member 7a of the fan motor 7, and the joint portion 11b is joined to the end surface of the sliding member 10, and then the same. A screw 8 is inserted into the screw insertion hole 11 d formed in the fixing plate 11 and screwed into the screw hole 7 b of the fan motor 7. Thereby, the mounting of the fan motor 7 to the base 1 is completed. Next, the blower fan 6 is connected to the drive shaft of the fan motor 7.
[0011]
When removing the fan motor 7 from the base 1 at the time of repair, etc., the screw screwed into the screw hole 7b is first removed, as shown in FIG. Remove the plate 11. Next, while the arc portion 10a of the sliding member 10 is slid in the sliding groove 9a, it is rotated in the direction indicated by the arrow and removed from the base 9. As a result, the non-drive shaft side of the fan motor 7 is opened, and the fan motor 7 can be pulled out in the horizontal direction.
[0012]
As described above, by fixing the drive shaft side of the fan motor 7 so as to be covered with the cap portion 12b, and fixing the counter drive shaft side with the sliding member 10 and the fixture 11, the fan motor 7 While the vibration generated from 7 can be suppressed as much as possible so as not to propagate to other parts, the fan motor 7 can be easily removed without removing the heat exchanger covering the surroundings at the time of repair or the like.
[0013]
【The invention's effect】
As described above, according to the present invention, the fan motor fixing device includes the cap portion that fixes the fan motor so as to cover the drive shaft side and the base portion that supports the cap portion on the base, and The non-drive shaft side of the fan motor is screwed to the base that is erected on the base, a sliding member that is slidably supported by the sliding groove of the base, and the rear surface of the fan motor. With the fixed plate, the vibration generated from the fan motor can be suppressed as much as possible, while the air motor can be easily removed from the fan motor at the time of repair or the like.
