  • the upper temporary fixing groove 1b is formed so as to have a depth equal to the diameter of the wire of the upper anchoring portion 51b2, and restricts movement, in the front and rear direction, of the upper anchoring portion 51b2 sandwiched by the side peripheral portion 3a of the top panel 3 and the surface 1h of the front panel 1.
  • a portion of the upper anchoring portion 51b2, being exposed from the opening of the upper temporary fixing groove 1b, is pressed by the side peripheral portion 3a of the top panel 3, and movement of the upper anchoring portion 51b2 in the forward direction is restricted. Movement of the upper anchoring portion 51b2 in the rearward direction is restricted by the upper temporary fixing groove 1b having a shape recessed toward the backside.
  • the depth of the upper temporary fixing groove 1b only needs to be a depth that allows the upper anchoring portion 51b2 to be sandwiched by the side peripheral portion 3a of the top panel 3 and the surface 1h of the front panel 1, and may be less than the diameter of the wire.
  • the upper anchoring portion 51b2 Since the upper anchoring portion 51b2 is press-fitted in the upper temporary fixing groove 1b, movement of the fan guard 5 in the right and left direction is restricted. Since the upper anchoring portion 51b2 is sandwiched by the front panel 1 and the top panel 3, movement of the fan guard 5 in the front and rear direction is restricted. Therefore, movement of the fan guard 5 due to vibrations during operation of the air-conditioning apparatus is prevented, and thus generation of noise is suppressed.
  • the fan guard 5 is attached before the top panel 3 is attached to the casing 10.
  • the fan guard 5 is located in front of the front panel 1. At this time, the fan guard 5 is inclined by tilting the upper ends of the upper anchoring portions 51b2 forward of the casing 10. After that, the lower anchoring distal end portions 51b4 of the lower anchoring portions 51b5 are brought close to the lower portion of the front panel 1 and inserted into the lower temporary fixing holes 1c formed in the front panel 1, and the lower anchoring portions 51b5 are engaged with the lower temporary fixing holes 1c.

  • the upper anchoring portions 51b2 are moved to the locations of the upper temporary fixing grooves 1b formed in the front panel 1.
  • the lower anchoring portions 51b5 contact with the lower edges 1p of the lower temporary fixing holes 1c, and movement of the lower anchoring portions 51b5 in the front and rear direction and in the downward direction is restricted. Therefore, the upper anchoring portions 51b2 move along predetermined trajectories and reliably reach the locations of the upper temporary fixing grooves 1b.
  • the upper anchoring portions 51b2 are pushed in toward the front panel 1 while being caused to contact with the lower edges 1p of the upper temporary fixing grooves 1b, and fitted into the upper temporary fixing grooves 1b.
  • the upper anchoring portions 51b2 are engaged with the upper temporary fixing grooves 1b.
  • the lower edges 1p of the upper temporary fixing grooves 1b have a curved surface 1f. This is because, when the lower edges 1p have the curved surfaces 1f, the upper anchoring portions 51b2 move along the curved surfaces 1f and easily engage with the upper temporary fixing grooves 1b.
  • the upper anchoring portions 51b2 and the lower anchoring portions 51b5 of the fan guard 5 are respectively engaged with the upper temporary fixing grooves 1b and the lower temporary fixing holes 1c, and the fan guard 5 is preliminarily fixed at a predetermined location of the casing 10. Thus, the fan guard 5 is temporarily fixed.
  • the upper anchoring portions 51b2 are inserted in the upper temporary fixing grooves 1b, and movement of the fan guard 5 in the front and rear direction and in the right and left direction is restricted.
  • the upper anchoring portions 51b2 of the fan guard 5 are press-fitted in the upper temporary fixing grooves 1b. Therefore, the fan guard 5 does not fall forward of the casing 10, and the fan guard 5 is kept attached to the casing 10. Hence, a worker does not need to hold the fan guard 5.
  • the top panel 3 is disposed on the casing 10 to which the fan guard 5 is temporarily fixed, and the four side peripheral portions 3a of the top panel 3 are fitted to the upper portion of the casing 10.

  • the upper anchoring portions 51b2 of the fan guard 5 are sandwiched by the side peripheral portion 3a of the top panel 3 and the surface 1h of the front panel 1.
  • the fan guard 5 is fixed to the casing 10. Attachment of the fan guard 5 completes.
  • the fan guard 5 Since the fan guard 5 is firmly fixed by the top panel 3, a forward drop-off of the fan guard 5 at the time when a large impact acts on the casing 10 is reduced. In addition, movement of the upper anchoring portions 51b2 and the lower anchoring portions 51b5 of the fan guard 5 in the front and rear direction and in the right and left direction is restricted, thus vibrations during operation are reduced, and noise due to vibrations is reduced. Furthermore, since the fan guard 5 is fixed by disposing the top panel 3 through clearance above the casing 10 and placing the top panel 3 to cover the casing 10, space required for attachment is reduced. In addition, fastening with a screw is not required, and therefore attachment is facilitated.
  • the top panel 3 is detached, and the fan guard 5 is placed in a temporary fixed state. Then, the upper anchoring portions 51b2 are pulled out from the upper temporary fixing grooves 1b, the upper end of the fan guard 5 is pivoted in a direction to move forward, and then the fan guard 5 is raised upward to pull the lower anchoring portions 51b5 out from the lower temporary fixing holes 1c. Thus, detaching of the fan guard 5 completes.
  • the upper anchoring portion 51b2 and the lower anchoring portion 51b5 both are provided in the first vertical bar 51b. Instead, the upper anchoring portion 51b2 and the lower anchoring portion 51b5 may be respectively provided in different vertical bars. It is desirable that each of the set of upper anchoring portions 51b2 and the set of lower anchoring portions 51b5 be provided at bilaterally symmetric locations. This is because, with this configuration, forces that act on the fan guard 5 reach equilibrium. Furthermore, the upper anchoring portion 51b2 may be provided at least in one vertical bar located at the center.

  • the outdoor unit 100 for an air-conditioning apparatus according to the modification includes protrusions 11b2 formed in the upper temporary fixing groove 11b of the front panel 1.
  • the D-D section is a section of the casing 10, in the right and left direction, and is a section passing through the center of the upper temporary fixing groove 11b.
  • the upper temporary fixing groove 11b has the protrusions 11b2 formed at the front side.
  • Each of the protrusions 11b2 is formed at the edge of the recessed shape of the upper temporary fixing groove 11b along, for example, part of the upper temporary fixing groove 11b in a longitudinal direction or a ridge 11b1 of the edge.
  • the diameter of a circle drawn by an inner wall surface 1b3 of the upper temporary fixing groove 11b and tangents of the protrusions 11b2 is equal to the diameter of the upper anchoring portion 51b2.
  • the upper anchoring portion 51b2 When the upper anchoring portion 51b2 is press-fitted into the upper temporary fixing groove 11b, the upper anchoring portion 51b2 is held by the protrusions 11b2, and movement in the right and left direction and in the forward direction is restricted. With the thus configured protrusions 11b2, the upper anchoring portion 51b2 is prevented from coming off from the upper temporary fixing groove 11b. In addition, for example, even when the outdoor unit 100 is manufactured without dimensional control for press-fitting, the upper anchoring portion 51b2 is held, and movement in the right and left direction and in the front and rear direction due to vibrations is restricted.
  • the upper anchoring portions 51b2 and lower anchoring portions 51b5 of the fan guard 5 are inserted into the upper temporary fixing grooves 1b and lower temporary fixing holes 1c of the front panel 1, and the fan guard 5 is temporarily fixed to the casing 10. Then, when the top panel 3 is placed on the casing 10 to which the fan guard 5 is temporarily fixed, the fan guard 5 is fixed. In a temporarily fixed state, movement of the upper anchoring portions 51b2 in the up and down direction is restricted by the upper temporary fixing grooves 1b, and movement of the lower anchoring portions 51b5 in the up and down direction and in the front and rear direction is restricted by the lower temporary fixing holes 1c.
  • the upper temporary fixing groove 1b is an opening that opens on the front of the casing, and allows the upper anchoring portion 51b2 to be inserted therein when the upper anchoring portion 51b2 is pushed in.

  • the width of the upper temporary fixing groove 1b By allowing the width of the upper temporary fixing groove 1b to be equal to or less than the diameter of the upper anchoring portion 51b2, movement of the upper anchoring portion 51b2 press-fitted in the upper temporary fixing groove 1b, in the right and left direction can be restricted, and the upper anchoring portion 51b2 can be held.
  • the upper anchoring portion 51b2 With the protrusions 11b2 of the upper temporary fixing groove 11b, the upper anchoring portion 51b2 is prevented from coming off from the upper temporary fixing groove 11b. In addition, even when the outdoor unit 100 is manufactured without dimensional control for press-fitting, the upper anchoring portion 51b2 is held, and movement of the upper anchoring portion 51b2 in the right and left direction and in the front and rear direction due to vibrations is restricted.
  • the lower anchoring portion 51b5 contacts with the lower edge 1p when the lower anchoring portion 51b5 moves forward, and movement of the lower anchoring portion 51b5 in the forward direction is restricted.
  • the contact portions 52b3 and lower anchoring distal end portions 51b4 of the fan guard 5 contact with the casing 10, and apply opposite forces to the fan guard 5. Therefore, movement of the fan guard 5 in the forward direction is restricted by the contact portions 52b3, movement of the fan guard 5 in the rearward direction is restricted by the lower anchoring portions 51b5, and movement of the fan guard 5 due to vibrations is reduced.
