  When performing maintenance service of components such as a heat exchanger and a blower installed in an outdoor unit of an air conditioner, the blower holding member may be attached and detached. At that time, it is necessary to attach and detach the top plate and front plate of the outdoor unit. The above-mentioned Patent Document 1 has a structure in which the fan holding member is fixed by a top plate fixing screw. For products with an air outlet on the top surface of the outdoor unit, there is sufficient space above the outdoor unit to blow out air, so the nut or screw for fixing the top panel can be attached and removed with a nut driver or screwdriver. There is no hindrance to the work to do and the work to attach and remove the blower holding member.

However, in the product having a blowout port on the front surface of the outdoor unit as in Patent Document 2, the top plate is screwed on the side surface of the outdoor unit, and the upper part of the blower holding member is on the back side of the top plate and the upper part of the front plate. It is fixed. The reason why the upper part of the blower holding member is fixed is to ensure the strength when a large-capacity blower is disposed in the outdoor unit.
For products that have a blowout port on the front surface of the outdoor unit, the outdoor unit may be installed on the top of the veranda using a suspension stand. In such a case, since sufficient work space cannot be secured at the top of the outdoor unit, an operator can put his hand in a narrow space and attach / remove the top plate fixing screw on the rear surface of the outdoor unit and the top fixing screw of the blower holding member that cannot be seen. There was a problem that it was difficult to do. When the fan holding member is screwed to the top surface of the outdoor unit on the top plate, there is no space for using a tool such as a screwdriver and it is difficult to attach and remove the upper fixing screw of the fan holding member. It was. Moreover, in the structure which fixes the upper part of an air blower holding member to a front plate, there existed a problem that it was necessary to enlarge the shape of an air blower holding member or to add a new component.

  This invention was made in order to solve the above-mentioned subject, and even when the work space in the upper part of an outdoor unit is narrow, it does not enlarge the shape of a fan holding member, or adds a part, and it is a fan. An object of the present invention is to obtain an outdoor unit of an air conditioner that facilitates attachment / detachment of an upper fixing screw of a holding member.

An outdoor unit of an air conditioner according to the present invention includes a casing including at least a top plate, a blower arranged in the casing, and a blower holding member for holding the blower in the casing. In the outdoor unit of the type air conditioner, the top plate is inclined with respect to the front surface of the outdoor unit and has a first inclined plane having a punched hole, and a convex portion or a concave portion having the first inclined plane. When have, the blower holding member has, in its upper part, facing the first inclined plane and a second inclined plane having a screw hole at a position aligned with the vent hole, the top plate An engaging portion that engages with the projecting portion or the recessed portion, and the projecting portion or recessed portion of the top plate and the engaging portion of the blower holding member are engaged, and the punched hole and the screw hole are positioned. is, obliquely from above of the top plate, screws are screwed in the screw hole through the drain hole, said feeding In which machine holding member is detachably fixed to the top plate.

  In this invention, since the screw is screwed with the screw hole of the blower holding member through the hole in the top plate from the diagonally upper front of the outdoor unit, or the screw can be removed, the work space above the outdoor unit is reduced. Even in a narrow case, it is possible to easily attach and remove the upper fixing screw of the blower holding member without increasing the shape of the blower holding member or adding parts.
