  Thus, here, an outdoor unit of an air conditioner (hereinafter simply referred to as an “outdoor unit of an air conditioner”) having a flexible carrying handle that is detachably fitted to the mounting opening of the housing panel. ) Will be described. FIG. 5 is an exploded perspective view of the outdoor unit 1 of the air conditioner. As shown in FIG. 5, in the outdoor unit 1 of an air conditioner, a front panel 3 and a rear panel 4 are assembled to the unit body 2, and an upper panel 5 is assembled to the front panel 3 and the rear panel 4. It is done. Further, on the side surfaces of the front panel 3 and the rear panel 4, a transport handle 6 having a certain degree of elasticity and hardness is fitted by being made of resin or the like.

  In this regard, the transport handle 6 is fitted as shown in FIGS. 6 (a) and 6 (b). FIG. 6 is a view showing a method of fitting the transport handle 6 in the outdoor unit 1 of the air conditioner. That is, as shown in FIG. 6 (a), a mounting port 7 is provided on the side surface of the front panel 3, and the carrying handle 6 is provided to the mounting port 7 as shown in FIG. 6 (b). Is inserted. Although not shown in FIG. 6, the transport handle 6 is similarly fitted to the side surface of the rear panel 4.

  And the handle 6 for conveyance has the structure shown in FIG. 7 in order not to fall out from the attachment port 7 naturally. FIG. 7A is an upper perspective view of the transport handle 6, FIG. 7B is a lower perspective view of the transport handle 6, and FIG. 7C is a side view of the transport handle 6. That is, three upper engaging claws 6A are formed on the upper part of the carrying handle 6 as shown in FIGS. 7 (a) and 7 (c). Further, as shown in FIGS. 7B and 7C, three lower engaging claws 6 </ b> B are formed in the lower portion of the transport handle 6. Further, as shown in FIGS. 7A, 7 </ b> B, and 7 </ b> C, a projecting edge portion 6 </ b> D is formed around the opening 6 </ b> C of the carrying handle 6 that is hand-held. Accordingly, as shown in FIG. 7C, a gap α is formed between the upper engaging claw 6A / lower engaging claw 6B and the protruding edge portion 6D.

  At this time, as shown in FIG. 8, the shortest dimension from the upper edge to the lower edge of the attachment port 7 is B, and from the lower end of the upper engaging claw 6A of the transport handle 6 as shown in FIG. When the shortest dimension to the lower end of the lower engaging claw 6B (the shortest dimension from the upper end of the upper engaging claw 6A of the carrying handle 6 in FIG. 9 to the upper end of the lower engaging claw 6B is the same) is A. The dimension A of the handle 6 is slightly larger than the dimension B of the attachment port 7.

  Therefore, in order to fit the transport handle 6 into the mounting port 7, it is necessary to push the transport handle 6 into the mounting port 7 with a little force, and at this time, the transport handle having a certain degree of elasticity. The handle 6 shrinks, and when the dimension A of the transport handle 6 becomes equal to the dimension B of the mounting port 7, the transport handle 6 is fitted into the mounting port 7. After the transport handle 6 is fitted into the attachment port 7, the transport handle 6 having a certain degree of elasticity is stretched, and the dimension A of the transport handle 6 is slightly larger than the dimension B of the mounting port 7. Returning to FIG. 9, as shown in FIG. 9, the upper and lower edges of the attachment port 7 enter the gap α formed between the upper engagement claw 6A / lower engagement claw 6B and the protruding edge portion 6D. 7 is completed. At this time, as shown in FIG. 9, since the dimension A of the transport handle 6 is slightly larger than the dimension B of the attachment port 7, the transport handle 6 does not naturally fall out of the attachment port 7.

  However, in a state where the transport handle 6 is fitted into the attachment port 7, as shown in FIG. 9, the transport handle 6 is transported in the gap α formed between the lower engaging claw 6B and the projecting edge portion 6D. Since the lower part of the handle 6 is in contact with the lower edge of the attachment port 7, the gap between the upper engaging claw 6 </ b> A and the protruding edge part 6 </ b> D of the transport handle 6 is There was a gap β between the upper edges of the attachment port 7. And this clearance (beta) was a factor which the handle 6 for conveyance vibrates while the outdoor unit 1 of an air conditioner is driving | operating.

  Of course, in order to eliminate the gap β, the dimension B of the mounting port 7 may be reduced. In this case, even if the transport handle 6 is pushed into the mounting port 7 with force, the transport handle 6 is not If the transport handle 6 cannot be fitted into the mounting port 7 and the dimension A of the transport handle 6 is reduced as a countermeasure, the upper handle is engaged when the warp of the transport handle 6 is large. The engagement allowance between the claw 6A and the lower engagement claw 6B becomes small, and there is a possibility that the transport handle 6 may come off from the attachment port 7 naturally.

  Therefore, by simply reducing the dimension A of the transport handle 6 and the dimension B of the mounting port 7 so as to eliminate the gap β that is a cause of vibration of the transport handle 6, the transport handle 6 is connected to the mounting port 7. Since it may become impossible to fit or the transport handle 6 may fall out of the attachment port 7 naturally, it has been required to eliminate the vibration of the transport handle 6 by another means.

  Accordingly, the present invention has been made in view of the above-described points, and is an air conditioner that prevents vibration of a flexible transport handle that is detachably fitted to a mounting opening of a housing panel. It is an object to provide an outdoor unit.

The fifth dimension from the upper edge of the mounting opening of the housing panel to the upper end of the projecting piece on the lower edge is from the lower end of the upper groove to the upper end of the lower groove . Since it is equal to the sixth dimension , the carrying handle can be fitted into the mounting opening of the housing panel. At this time, the housing is placed in the upper groove formed by the gap between the projecting edge of the carrying handle and the upper engaging claw. When the upper edge of the mounting opening of the body panel is engaged, and the lower edge of the mounting opening of the housing panel is engaged in the lower groove formed by the gap between the protruding edge of the carrying handle and the lower engaging claw, the housing panel the fifth dimension from the upper edge of the mounting opening to the protruding piece upper end of the lower edge of the lower end of the upper groove of the carrying handle to the upper end of the lower groove of Since approximately equal to 6 dimensions, since carrying handle to the mounting opening of the housing panel is held, the vibrations of the carrying handle of the removable flexible to be fitted to the mounting opening of the housing panel Can be prevented.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Since the outdoor unit of the air conditioner according to the present embodiment is an improvement of the outdoor unit 1 of the air conditioner already described in the background art section, the same components are denoted by the same reference numerals and are described. Omitted, here, different configurations will be described in detail.

  In the outdoor unit 1 of the air conditioner of the present embodiment, as shown in FIG. 2, two locking pieces 7 </ b> A are projected from the lower edge of the attachment port 7. In this regard, as shown in FIG. 2, the shortest dimension from the upper edge of the attachment port 7 to the locking piece 7A at the lower edge is D, and as shown in FIG. 3, the shortest distance from the top to the bottom of the carrying handle 6 When the dimension is C, the dimension D of the attachment port 7 is equal to the dimension C of the carrying handle 6. Strictly speaking, the dimension D of the attachment port 7 is larger than the dimension C of the carrying handle 6 by the dimensional tolerance at the time of molding. Further, as shown in FIG. 2, the shortest dimension in the interval between the two locking pieces 7A on the lower edge of the attachment port 7 is E, and the three lower engagements of the transport handle 6 are shown in FIG. Assuming that the shortest dimension of the width of the claw 6B is F, the dimension E of the attachment port 7 is slightly larger than the dimension F of the carrying handle 6. Further, as shown in FIG. 2, the shortest dimension in the width of each locking piece 7A at the lower edge of the attachment port 7 is G, and as shown in FIG. 4, the three lower engaging claws 6B of the carrying handle 6 are shown. Assuming that the shortest dimension in the interval is H, the dimension G of the attachment port 7 is slightly smaller than the dimension H of the carrying handle 6. Further, the locking piece 7A on the lower edge of the attachment port 7 is disposed so as to face the interval between the three lower engaging claws 6B of the conveyance handle 6 when the conveyance handle 6 is fitted into the attachment port 7. Is done.

  In order to fit the transport handle 6 into the attachment port 7, the upper edge of the attachment port 7 is inserted into the gap α formed between the upper engaging claw 6 </ b> A and the protruding edge portion 6 </ b> D, and then the transport handle. 6 is pushed into the mounting port 7 with a little force, and the lower edge of the mounting port 7 is inserted into the gap α formed between the lower engaging claw 6B and the protruding edge portion 6D. At this time, since the locking piece 7A on the lower edge of the attachment port 7 passes through the space between the three lower engaging claws 6B of the carrying handle 6, the locking piece 7A on the lower edge of the attachment port 7 is conveyed. There is no collision / interference with the three lower engaging claws 6B of the handle 6.

  In this way, when the transport handle 6 is fitted into the attachment port 7, the state as shown in FIG. 1 is obtained, and the lower part of the transport handle 6 contacts the locking piece 7 </ b> A on the lower edge of the attachment port 7. Since the upper part of the transport handle 6 comes into contact with the upper edge of the mounting port 7 and the transport handle 6 is pressed against the mounting port 7, the transport handle is operated while the outdoor unit 1 of the air conditioner is in operation. 6 does not vibrate. However, even in such a state, a gap α is generated between the lower edge of the attachment port 7 and the lower portion of the carrying handle 6 except for the locking piece 7A on the lower edge of the attachment port 7.

  When two locking pieces 7A are projected on the upper edge of the attachment port 7 instead of the lower edge of the attachment port 7, it is formed between the upper engagement claw 6A and the projection edge 6D. After the upper edge of the attachment port 7 is inserted into the gap α, the transport handle 6 is pushed into the attachment port 7 with a little force and is formed between the lower engaging claw 6B and the protruding edge portion 6D. When the lower edge of the attachment port 7 is inserted into the gap α, the transport handle 6 rotates around the protruding end of the locking piece 7A protruding from the upper edge of the attachment port 7 at this time. Since the carrying handle 6 having the dimension A (see FIG. 7C) is fitted to the dimension D of the port 7, it is difficult to fit the carrying handle 6 into the mounting port 7.

  As described above in detail, in the outdoor unit 1 of the air conditioner according to the present embodiment, the front panel 3 and the rear panel 4 provided with the mounting ports 7 and the mounting ports 7 of the front panel 3 and the rear panel 4 are provided.

The lower edge of the mounting opening 7 of the front panel 3 and rear panel 4 is inserted between the claws 6B. The lower edge of the mounting opening 7 of the front panel 3, rear panel 4 abuts the lower portion of the carrying handle 6.

  Further, the outdoor unit 1 of the air conditioner according to the present embodiment includes a locking piece 7A that protrudes from the lower edge toward the upper edge of the mounting opening 7 of the front panel 3 and the rear panel 4, and the front panel 3 The locking piece 7A on the lower edge of the mounting opening 7 of the rear panel 4 is connected to the lower engaging claw 6B of the transporting handle 6 when the transporting handle 6 is fitted into the mounting opening 7 of the front panel 3 and the rear panel 4. Are arranged at locations where they do not collide, and the shortest dimension D from the upper edge to the lower edge locking piece 7A of the mounting opening 7 of the front panel 3 and rear panel 4 is the shortest dimension C from the top to the bottom of the carrying handle 6 It is equal to.

That is, in the outdoor unit 1 of the air conditioner according to the present embodiment, the locking piece 7A on the lower edge of the mounting opening 7 of the front panel 3 / rear panel 4 is connected to the mounting opening 7 of the front panel 3 / rear panel 4 by a carrying handle. 7 is disposed at a position where it does not collide with the lower engaging claw 6B of the carrying handle 6 when the handle 6 is fitted, and the locking piece 7A from the upper edge to the lower edge of the mounting opening 7 of the front panel 3 / rear panel 4 Since the shortest dimension D is equal to the shortest dimension C from the upper part to the lower part of the transport handle 6, the transport handle 6 can be fitted into the mounting opening 7 of the front panel 3 and the rear panel 4. At this time, the upper edge of the mounting opening 7 of the front panel 3 and the rear panel 4 is inserted between the protruding edge 6D of the carrying handle 6 and the upper engaging claw 6A, and the protruding edge 6D and the lower part of the carrying handle 6 are engaged. Front panel 3 and rear panel between engaging claws 6B When the lower edge of the attachment port 7 is engaged, the shortest dimension D from the upper edge of the attachment port 7 of the front panel 3 and the rear panel 4 to the locking piece 7A of the lower edge is the shortest from the upper part to the lower part of the carrying handle 6 Since it is equal to the dimension C, the upper edge of the mounting opening 7 of the front panel 3 and rear panel 4 abuts on the upper part of the carrying handle 6 and the locking piece 7A on the lower edge of the mounting opening 7 of the front panel 3 and rear panel 4 is provided. Since the carrying handle 6 is held in contact with the lower portion of the carrying handle 6 and is held between the mounting openings 7 of the front panel 3 and the rear panel 4, it is detachably fitted to the fitting openings 7 of the front panel 3 and the rear panel 4. The vibration of the flexible carrying handle 6 can be prevented.
However, in the outdoor unit 1 of the air conditioner of the present embodiment, if the relationship of the dimensional tolerance is strictly evaluated, from the upper edge of the mounting opening 7 of the front panel 3 and the rear panel 4 to the locking piece 7A of the lower edge. Since the shortest dimension D is slightly larger than the shortest dimension C from the upper part to the lower part of the transport handle 6, there is a slight gap between the upper edge of the mounting opening 7 of the front panel 3 and the rear panel 4 and the upper part of the transport handle 6. It can be said that the carrying handle 6 is clamped in the attachment opening 7 of the front panel 3 and the rear panel 4 in a state where a gap is generated. Therefore, even if the upper edge of the mounting opening 7 of the front panel 3 and the rear panel 4 does not contact the upper part of the carrying handle 6, it is flexible to be detachably fitted to the mounting opening 7 of the front panel 3 and the rear panel 4. It is possible to obtain the effect of preventing vibration of the sex carrying handle 6.

  Therefore, in the outdoor unit 1 of the air conditioner according to the present embodiment, a flexible carrying handle that is detachably fitted to the mounting ports 7 of the front panel 3 and the rear panel 4 even during operation. There is no vibration of 6 and vibration sound unpleasant to the user is not generated, and further, deterioration and destruction of the transport handle 6 due to vibration noise can be suppressed.

In addition, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the meaning.
For example, in the outdoor unit 1 of the air conditioner of the present embodiment, the number of the locking pieces 7A on the lower edge of the attachment port 7 is equal to the number of intervals between the lower engaging claws 6B in the transport handle 6. Thus, for example, if the number of intervals between the lower engaging claws 6B in the transport handle 6 is “3”, the number of the locking pieces 7A on the lower edge of the attachment port 7 is also “3”. Further, in this case, the same effect can be obtained even if the locking pieces 7A on the lower edge of the mounting port 7 are attached so as to sandwich the both sides of the lower engaging claw 6B in the carrying handle 6.

  In addition, when the two locking pieces 7A are projected on the upper edge of the mounting port 7 instead of the lower edge of the mounting port 7, it is formed between the lower engaging claw 6B and the projecting edge 6D. After the lower edge of the attachment port 7 is inserted into the gap α, the transport handle 6 is pushed into the attachment port 7 with a little force, and is formed between the upper engaging claw 6A and the protruding edge portion 6D. If the upper edge of the attachment port 7 is inserted into the gap α, the carrying handle 6 can be fitted into the attachment port 7.
