[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fan motor mounting structure for an air conditioner.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 3, an air conditioner of this type is provided with an outdoor heat exchanger 4 on the outside of a main body 1 partitioned by a partition plate 3 attached to a bottom plate 2, and inside the inside thereof. An axial fan 5 is provided, and the fan 5 is surrounded by a baffle plate 6 having a ventilation hole 7. An indoor heat exchanger 9 and a centrifugal fan 8 are sequentially provided on the indoor side, and the axial fan 5 and the centrifugal fan 5 are centrifugally connected. The fan 8 was driven by the fan motor 10 attached to the partition plate 3. As shown in FIG. 4, the fan motor 10 has three legs 10a with through holes formed in the end face, and is fixed to the three mounting bolts 3a planted in the partition plate 3 via the cushioning material 3b. It is fixed. A motor pedestal 2a is provided on the bottom plate 2 below the fan motor 10 via a cushioning material 2b in consideration of a case where the motor is accidentally dropped during transportation. However, as the fan motor 10 rotates, the partition plate 3 vibrates, and the partition plate 3 has a large area and is enlarged, which is a major cause of noise in the air conditioner.

【Example】

 An embodiment of an air conditioner according to the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a plan view of the inside of the present air conditioner, in which an outdoor heat exchanger 4 is arranged on the outdoor side in a main body 1 partitioned by a partition plate 3 attached to a bottom plate 2, and an axial fan is provided inside thereof. 5, the fan 5 is surrounded by a baffle plate 6 having a ventilation hole 7, and an indoor heat exchanger 9 and a centrifugal fan 8 are sequentially installed on the indoor side, and the axial fan 5 and the centrifugal fan 8 are provided. A fan motor 10 and a compressor 11 that drive the motor are provided between the partition plate 3 and the baffle plate 6. FIG. 2 is a side view of the main part, in which the fan motor 10 is supported by a support plate 12 attached to the bottom plate 2, and a holding plate 14 bridged between the partition plate 3 and the baffle plate 6 is provided with a cushioning material 15 interposed therebetween. It shows the state of being held. This will be described in detail. The support plate 12 has a screw hole for bending the lower end and fixing it to the bottom plate 2, and a through hole for inserting the fan motor 10 in the upper part and one screw hole for each of the upper and lower parts. It is a solid metal plate that has been drilled. Separately, a motor case 13 for accommodating the fan motor 10 is provided. This is divided into two parts in the axial direction of the motor, and projecting pieces 13a are provided above and below each of the facing openings to form a pair of screw holes facing the screw holes of the support plate 12, respectively. The end face is provided with a through hole through which the motor shaft is inserted, and an attachment piece 13b having an attachment pin 13c implanted in the same direction is provided on the upper portion. Both of the screw holes of the projecting piece 13a may be through holes, or one side may be provided with a female screw, and the mounting piece 13b is provided from directly above in consideration of the screwing of the projecting piece 13a. It is advisable to move the motor in the same direction as the motor rotation direction and in the opposite direction by the same angle. The holding plate 14 is a metal plate that has a width about the diameter of the motor case 13 and is bridged by the partition plate 3 and the baffle plate 6 and has its end bent downwards. A portion slightly longer than the length is lowered by an appropriate depth, and two portions of the bottom surface thereof are cut and raised to hang down, and a slightly large through hole is formed as a holding piece 14a facing the mounting pin 13c. .. The cushioning material 15 is, for example, a columnar elastic body such as rubber, and is provided with a through hole through which the mounting pin 13c is inserted and a recessed portion that is fitted into the through hole of the holding piece 14a.

The fan motor 10 is incorporated in the air conditioner as follows. That is, referring to FIG. 2, the fan motor 10 is inserted into the through hole of the support plate 12, the motor case 13 divided into two is covered from both sides, and the upper and lower projections 13a of the opening are screwed into the screw holes of the support plate 12. Secure with screws or bolts and nuts through. The cushioning material 15 is fitted into the pair of holding pieces 14 a of the holding plate 14, and the end portions of the pair of mounting pins 13 c are brought into contact with the through holes of the cushioning material 15 to bring the motor case 13 into the holding plate 14. When slid, the motor case 13 is held by the holding plate 14. When arranging the integrated unit at a predetermined position, tilt the whole body to the right and insert the tip of the long motor shaft to mount the axial fan 5 into the ventilation hole 7 and partition the short motor shaft to mount the centrifugal fan 8 into. Move it to the right side so that it does not hit the plate 3 and then lower it horizontally, and move it to the left just before the upper part of the holding plate 14 contacts the upper ends of the partition plate 3 and the air guide plate 6 to partition the short motor shaft. The support plate 12 and the holding plate 14 are fixed to the bottom plate 2 and the partition plate 3 to the baffle plate 6 with screws by inserting them through the holes of the plate 3 and lowering them to bring the lower end of the support plate into contact with the bottom plate 2. Removal is the reverse of the above.

[0008]

[Effect of the device]

 As described above, according to the present invention, the bottom plate has a strong structure for mounting all the constituent members of the air conditioner, is reinforced by the mounting of these members, and is less susceptible to vibration under load. Since the fan motor is attached to the fan motor, vibration of the fan motor is suppressed, noise is greatly reduced, and the fan motor can be easily attached and detached.
