Description

  The present invention relates to an outdoor unit of an air conditioner.

  Conventionally, as an outdoor unit of this type of air conditioner, for example, as shown in FIG. 7, a motor 70 of an outdoor unit of an air conditioner is a motor fixed inside an outdoor unit box (not shown). Attached to the base 71.

  That is, the motor base 71 is provided with a motor fitting hole 72 at the center thereof, and with respect to the fitting hole 72, a plurality of screw holes 73 are provided on the circumference, and the bent piece extends in the horizontal direction from the lower end. 74, and the bent piece 74 is fixed to the bottom plate of the outdoor unit box.

Moreover, the bending piece 75 extended horizontally from the upper end of the motor base 71 is provided, and this bending piece 75 is being fixed to the front board of the outdoor unit box (for example, refer patent document 1).
JP-A-8-128665

  However, in the conventional configuration, in order to attach the motor 70 to the motor base 71, the outer shell 76 of the motor 70 is fitted into the motor fitting hole 72 of the motor base 71, and in this state, the bolt member is attached to the fan motor. While being inserted into the leg 77 and fixed to the screw hole 73 provided in the motor base 71, the motor 70 is attached by fitting the outer shell 76 of the motor 70 into the fitting hole 72 of the motor base 71 as described above. It is necessary to tighten a bolt member after making it.

  And the operator had to perform the next screw fastening operation | work, hold | maintaining the state which fitted the motor 70. FIG. For this reason, there is a problem that the motor falls off if the work is difficult and cannot be held. Moreover, the same problem was encountered when the motor 70 was replaced.

  The present invention solves the above-mentioned conventional problems, and prevents the motor from falling off in a non-fixed state of the motor, i.e., a state where the operator has released his hand from the motor. An object of the present invention is to provide an outdoor unit of an air conditioner with improved detachability.

  In order to solve the above-mentioned conventional problems, the outdoor unit of the air conditioner of the present invention supports the outer shell of the motor from the lower side with the fan motor not fixed to the motor base, and is located before the center of gravity of the fan motor in the rotation axis direction. The structure is provided with a support body that is positioned and prevents the fan motor from falling off.

  Thus, the motor can be prevented from dropping off when the operator removes his / her hand from the motor, and the detachability during motor installation and replacement can be improved.

  The outdoor unit of the air conditioner according to the present invention can prevent the motor from dropping off when the operator removes his / her hand from the motor, and can improve the detachability during motor mounting and replacement.

  According to a first aspect of the present invention, the fan motor base is provided with a support body that supports the motor casing from below when the fan motor is not fixed, and prevents the fan motor from falling off before the center of gravity of the fan motor in the rotational axis direction. Thus, the fan motor can be prevented from falling off even when the fan motor is not fixed.

  According to the second aspect of the present invention, even if the fan motor is in the non-fixed state by providing a support body for preventing the fan motor from dropping off, particularly in the vicinity of the fan motor mounting portion of the fan motor base of the first aspect of the invention. The fan motor can be prevented from falling off.

  According to the third aspect of the invention, the fan motor can be stably supported by making the tip of the support body of the first aspect of the invention the same arc shape as the outer shape of the fan motor, and the fan motor is not fixed. Even so, it is possible to prevent the fan motor from falling off.

  According to the fourth aspect of the present invention, the fan motor can be mounted without interfering with the cord take-out portion of the fan motor, particularly when the fan motor is mounted by providing a notch in the center of the front end of the support of the first invention. Even when the fan motor is not fixed, it is possible to prevent the fan motor from falling off.

  The fifth aspect of the invention is particularly simple because the support body of the first aspect of the present invention is constituted by an upright piece erected from the fan motor base, and the fan motor is simple even when the fan motor is in an unfixed state. It is possible to provide a low-cost fan motor base that can prevent the falling off.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The present invention is not limited by the embodiment of the present invention.

(Embodiment 1)
1 is an exploded perspective view of an outdoor unit of an air conditioner according to a first embodiment of the present invention, FIG. 2 is a perspective view of a fan motor, FIG. 3 is a perspective view of a fan motor base, and FIG. 4 is a fan motor base. The side view of the state which fixed the fan motor to is shown.

  1 and 2, an outdoor unit body 1 includes a compressor 2, a heat exchanger 3, a fan motor 4, and a fan 5. The fan motor 4 is fixed to the outdoor unit body 1 by a fan motor base 6. ing.
