Here, by forming the cut-and-raised portion 331 in the horizontal portion 33a of the bottom plate 33, a large opening 330c is formed at a position between the small openings 330a and 330b.

  The cut-and-raised part 331 is formed at a position such that the upper surface thereof is positioned in the vicinity of the back surface of the fixing part 422 of the fan motor base 281 when the insertion parts 413a and 413b are inserted into the inserted parts 333a and 333b. ing. Further, the cut-and-raised part 331 includes a first screw hole 331a formed in the cut-and-raised part 331 and a fixing part 422 of the fan motor base 281 in a state where the insertion parts 413a and 431b are inserted into the inserted parts 333a and 333b. The second screw hole 422a is formed at a position where the second screw hole 422a overlaps in front view (that is, the first screw hole 331a and the second screw hole 422a face each other).

  Hereinafter, a method for attaching the fan motor base 281 to the bottom plate 33 will be described with reference to FIGS.

<Attaching method of fan motor base 281 to bottom plate 33>
FIG. 13 is a schematic diagram viewed from the front to show the positional relationship between the insertion portion 413a and the insertion portion 333a in a state where the insertion portion 413a is inserted into the insertion portion 333a. FIG. 14 is a schematic diagram of the fan motor base 281 and the bottom plate 33 for illustrating a state in which the fan motor base 281 is fixed to the bottom plate 33. FIG. 15 is a schematic view seen from the front of the insertion portion 413a and the insertion portion 333a for showing a state where the insertion portion 413a is placed on the upper surface of the insertion portion 333a.

  First, the insertion portions 413 a and 413 b of the fan motor base 281 are inserted into the insertion portions 333 a and 333 b of the bottom plate 33 by the installer or the like. Specifically, a part of the insertion portions 413a and 413b is inserted into the space S2 formed inside the inserted portions 333a and 333b. More specifically, as shown in FIG. 13, the contact surfaces 433a, 433b, 433c, 433d of the insertion portions 413a, 413b are respectively connected to the contact surfaces 334a, 334b, 334c, 334d of the insertion portions 333a, 333b. The insertion portion 413a of the fan motor base 281 is inserted into the inserted portions 333a and 333b of the bottom plate 33 so as to come into contact with each other. FIG. 13 shows only the insertion portion 413a and the insertion portion 333a, but the same applies to the insertion portion 413b and the insertion portion 333b.

  Here, as described above, the width W1 in the first direction of the upper surface side protruding portions 336a and 336b is not more than half of the width W2 in the first direction of the inserted portions 333a and 333b, and the contacted portions 335a and 335a, It is less than or equal to half of the width W3 in the first direction between 335b, 335c, and 335d and the upper surface side protrusions 336a and 336b. Further, the width W4 in the first direction of the lower surface side protruding portions 423a and 423b is less than or equal to half of the width W5 in the first direction of the insertion portions 413a and 413b. Therefore, the insertion portions 413a and 413b and the inserted portions 333a and 333b have surfaces that can contact each other (specifically, the insertion portions 413a and 413b have contact surfaces 433a, 433b, 433c, and 433d, and the inserted portions 333a and 333b have contacted surfaces 334a, 334b, 334c, and 334d). Therefore, here, when the insertion portions 413a and 413b are inserted into the insertion portions 333a and 333b, the contact surfaces 433a, 433b, 433c, and 433d of the insertion portions 413a and 413b and the contact surfaces of the insertion portions 333a and 333b By allowing 334a, 334b, 334c, and 334d to contact each other, the fan motor base 281 can be temporarily supported by the bottom plate 33. Further, here, the insertion portions 413a and 413b are inserted into the inserted portions 333a and 333b, so that the deviation of the fan motor base 281 in the left-right direction (corresponding to the first direction) can be restricted.

  At this time (when the insertion portions 413a and 413b are inserted into the insertion portions 333a and 333b), the first screw hole 331a formed in the cut-and-raised portion 331 of the bottom plate 33 and the fixing portion of the fan motor base 281 The second screw holes 422a formed in the 422 are in a positional relationship such that they overlap each other when viewed from the front. At this time, the lower surface side protruding portions 423a and 423b of the insertion portions 413a and 413b are partially located in the small openings 330a and 330b.

  Next, as shown in FIG. 14, the second screw hole 422 a formed in the fixing part 422 of the fan motor base 281 and the first screw hole 331 a formed in the cut-and-raised part 331 of the bottom plate 33 by the installer or the like. In addition, a fixing screw 81 (corresponding to a fixing member) for fixing the bottom plate 33 and the fan motor base 281 is inserted, the fixing portion 422 is fixed to the raised portion 331, and the fan motor base 281 is fixed to the bottom plate. 33 is fixed. At this time, the cut and raised portion 331 is cut and raised from the horizontal portion 33a of the bottom plate 33 so as to be substantially parallel to the fixed portion 422. In this embodiment, the fixing screw 81 is used as a fixing member for fixing the bottom plate 33 and the fan motor base 281. However, this is an example, and other members such as bolts are used. Also good.

  Here, the insertion portions 413a and 413b have the lower surface side protruding portions 423a and 423b, respectively, as described above. Further, the inserted portions 333a, 333b are further higher than the contacted portions 335a, 335b, 335c, 335d, and the contacted portions 335a, 335b, 335c, 335d, which are higher in the vertical direction than the horizontal portion 33a of the bottom plate 33. It has upper surface side protrusions 336a and 336b which are located at high positions in the vertical direction.

  With the above configuration, for example, when inserting the insertion portions 413a and 413b into the insertion portions 333a and 333b, as shown in FIG. 15, one of the two insertion portions 413a and 413b corresponds to the insertion portion to be inserted. The first screw hole 331a and the second screw hole 331a and the second screw hole 331a may be placed on the upper surfaces of the 333a and 333b, that is, even if the fan motor base 281 is not positioned at the proper mounting position with respect to the bottom plate 33. A situation in which the fixing screw 81 can be inserted into the screw hole 422a can be avoided. That is, with the configuration as described above, it is possible to prevent the fan motor base 281 from being fixed to the bottom plate 33 in a state where the fan motor base 281 is inclined or displaced with respect to the normal mounting position. . Thereby, the original strength of the fan motor base 281 can be maintained.

  Further, for example, when the fan motor base 281 is displaced and fixed, the outdoor fan 28 fixed to the fan motor base 281 via the outdoor fan motor 28m is also displaced and disposed. At this time, there is a concern that the blade of the outdoor fan hits the bell mouth located in front of the outdoor fan. If you notice the contact between the outdoor fan and the bell mouth in the second half of the assembly process of the outdoor unit, it is assumed that the installers will have to start by attaching the fan motor base to the bottom plate again. The However, in the present embodiment, the fan motor base 281 cannot be fixed to the bottom plate 33 when the fan motor base 281 is displaced or inclined with respect to the normal mounting position. Therefore, the above situation can be suppressed.

<Characteristics of the outdoor unit 2 of the air conditioner 1 according to this embodiment>

Generally, in an outdoor unit of an air conditioner, an outdoor fan motor is fixed to a fan motor base that is fixed to a bottom plate that constitutes a lower surface of a casing. Here, as a method for fixing the bottom plate of the fan motor base, for example, a method disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 8-178361) can be cited. In the outdoor unit of an air conditioner disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 8-178361), a base corresponding to the bottom plate 33 of the present embodiment has two protrusions, a bolt mounting plate in which a hole is formed, Is provided. Further, the fan motor base has two mounting holes formed at the lower end thereof, and bolt insertion holes are formed at positions corresponding to the holes of the bolt mounting plate. Then, the fan motor base is fixed to the base by inserting the mounting hole through the protrusion and bolting the fan motor base and the bolt mounting plate through the bolt insertion hole and the hole of the bolt mounting plate.

  However, in the outdoor unit of an air conditioner as described above, even if one of the two mounting holes does not fit into one of the two protrusions (for example, the fan motor base on one upper surface of the protrusion). It is considered that the fan motor base may be able to be fixed to the bolt mounting plate with a bolt even if the lower surface of the fan is mounted. In this case, since the fan motor base is inclined more than the normal mounting position, there is a concern that the strength of the fan motor base may be affected. In this case, since the outdoor fan attached to the fan motor base is also inclined, there is a concern that the blades of the outdoor fan and the bell mouth generally provided on the front side portion of the outdoor unit of the air conditioner may hit. Is done. And if you notice the contact between the outdoor fan and the bell mouth in the second half of the assembly process of the outdoor unit, you must start again from the mounting on the bottom plate of the fan motor base, which may be troublesome for the installers Is done.

It has some upper surface side protrusion parts 336a and 336b. The insertion portions 413a and 413b have contact surfaces 433a, 433b, 433c, and 433d, and the insertion portions 333a and 333b have contact surfaces 334a, 334b, 334c, and 334d. Further, when the insertion portions 413 a and 413 b are inserted into the insertion portions 333 a and 333 b, the first screw holes 331 a formed in the cut-and-raised portion 331 of the bottom plate 33 and the fixing portion 422 of the fan motor base 281 are formed. It overlaps with the 2nd screw hole 422a in front view, and it becomes possible to insert the fixing screw 81 into the 1st screw hole 331a and the 2nd screw hole 422a.

  Such a configuration can prevent erroneous assembly of the fan motor base 281. That is, in a case where the fan motor base 281 is not located at a proper mounting position with respect to the bottom plate 33 (for example, when one of the insertion portions 413a and 413b is placed on the upper surface of the corresponding insertion portion 333a or 333b). The first screw hole 331a and the second screw hole 422a do not overlap in front view, and it becomes difficult to insert the fixing screw 81 into the first screw hole 331a and the second screw hole 422a. ing. Therefore, in the present embodiment, it is difficult to fix the fan motor base 281 to the bottom plate 33 under a situation where the fan motor base 281 is displaced or inclined from the normal mounting position. It is possible to prevent the fan motor base 281 from being fixed while being displaced from the normal mounting position with respect to the bottom plate 33.

(2)
In the present embodiment, the insertion portions 413a and 413b have contact surfaces 433a, 433b, 433c, and 433d, and the insertion portions 333a and 333b have contact surfaces 334a, 334b, 334c, and 334d. Thus, the fan motor base 281 can be supported by the bottom plate 33 when the insertion portions 413a and 413b are inserted into the insertion portions 333a and 333b. Thereby, it becomes easy for a construction worker etc. to perform construction, such as screwing of the fixing screw 81.

  Moreover, in this embodiment, the insertion part 413a, 413b is inserted in the to-be-inserted part 333a, 333b, Therefore The shift | offset | difference of the 1st direction of the fan motor base 281 can be controlled. Thereby, it becomes easy for a construction worker etc. to perform construction, such as screwing of the fixing screw 81.
