-
FIG. 1 is a perspective view of an outer appearance of the outdoor unit for an air-conditioning apparatus according to Embodiment of the present invention.FIG. 2 is an exploded perspective view of the outdoor unit illustrated inFIG. 1 . - In
FIGS. 1 and 2 , anoutdoor unit 50 according to Embodiment includes ahousing 51 formed of an L-shaped front panel 1, aside panel 2, a top panel 3, and abottom panel 4. In thefront panel 1, anair outlet 1 a is formed into a circular shape, and is covered with afan guard 1 b. On theside panel 2, aservice cover 5 and avalve cover 6 are mounted in a freely removable manner. On a lower surface of thebottom panel 4,foot sections 7 are mounted so as to fix theoutdoor unit 50 onto an installation surface. The inside of theoutdoor unit 50 is partitioned by a dogleg-shaped separator 8 into an air-sending device chamber 9 and amachine chamber 10. - An L-
shaped heat exchanger 11 and an air-sending device 12 arranged in front of theheat exchanger 11 are housed in the air-sending device chamber 9. In Embodiment, for example, a corrugated-fin heat exchanger including flat pipes, corrugated fins, and header pipes is employed as theheat exchanger 11. The air-sendingdevice 12 includes afan motor 12 a fixed to a fanmotor support member 20 described later, and apropeller fan 12 b. - When the
propeller fan 12 b is rotated through drive of thefan motor 12 a, air (outdoor air) is sucked through the rotation of thepropeller fan 12 b to pass through theheat exchanger 11 and flow into theoutdoor unit 50. Then, the air is caused to pass through thepropeller fan 12 b, and is blown outside from theair outlet 1 a of thefront panel 1 through thefan guard 1 b. Thus, during, for example, cooling operation, refrigerant inside theheat exchanger 11 is cooled by the air, and the air caused to pass through theheat exchanger 11 is heated into warm air through the heat exchange between the air and the refrigerant. - A
compressor 14 mounted on thebottom panel 4, a four-way valve, an expansion valve, a pipe connection section for connecting, to those components, a refrigerant pipe connected to an indoor unit, an electrical component for controlling the drive of thecompressor 14 and the air-sending device 12, and the like are housed in themachine chamber 10. - Next, the structure of the above-mentioned fan
motor support member 20 is described with reference toFIGS. 3 to 6 . -
FIG. 3 is a perspective view of the outdoor unit in a state in which the housing, the air-sending device, and the separator are removed inFIG. 2 .FIG. 4 is a perspective view of a size adjustment section to be used for the fan motor support member ofFIG. 2 as seen from the front side obliquely.FIG. 5 is a perspective view of the size adjustment section ofFIG. 4 as seen from the rear side obliquely.FIG. 6 is an enlarged sectional view of an upper part of the fan motor support member ofFIG. 3 as seen in the arrow A-A direction.FIG. 7 is a perspective view of an upper end portion side of the fan motor support member ofFIG. 3 as seen from the bottom side obliquely. - The fan
motor support member 20 is mounted in front of theheat exchanger 11. The fanmotor support member 20 includes a ladder-shapedsupport column section 21, aholding section 22 for the air-sendingdevice 12, which is arranged at a center portion of thesupport column section 21, supportcolumn fixing sections 23 each arranged at a lower end portion of thesupport column section 21, a plate-shaped toppanel support section 24 extending horizontally from an upper end portion of thesupport column section 21 toward the air-sendingdevice 12 side, and a lock andsupport section 25 extending horizontally from the upper end portion of thesupport column section 21 toward an opposite side to the toppanel support section 24. - The support
column fixing sections 23 are arranged at the front and rear of thesupport column section 21, and are fixed onto aconvex drawing portion 4 a formed on thebottom panel 4 by fasteningscrews 27 obliquely throughburring portions 4 b formed on the bottom panel 4 (seeFIG. 11 ). As illustrated inFIGS. 3 and 6 , the lock andsupport section 25 includes asupport plate 25 a extending horizontally from the upper end portion of thesupport column section 21, and an inverted U-shaped locking plate 26 (locking section) formed at a distal end of thesupport plate 25 a with adownward groove 26 d. As illustrated inFIG. 6 , on oneside surface 26 a forming thegroove 26 d of the invertedU-shaped locking plate 26, astepped portion 26 c having a flat surface is formed by bending a cut-and-raisedpiece 26 b upward at a right angle. The cut-and-raisedpiece 26 b is formed by cutting and raising a part of the center of theside surface 26 a outward. - The height of the above-mentioned fan
motor support member 20 is set in accordance with the height of, for example, a fin-and-tube heat exchanger. Further, the width of thegroove 26 d of the invertedU-shaped locking plate 26 is set to a dimension equal to or larger than the thickness of the fin-and-tube heat exchanger. That is, an upper end portion of the fin-and-tube heat exchanger is fitted into thegroove 26 d of the invertedU-shaped locking plate 26, thereby enabling to lock the fanmotor support member 20 onto the fin-and-tube heat exchanger. - A
size adjustment section 30 is fitted into thegroove 26 d of the invertedU-shaped locking plate 26 of the lock andsupport section 25. Thesize adjustment section 30 is provided so that the fanmotor support member 20 for the fin-and-tube heat exchanger may also be used for the corrugated-fin heat exchanger, which is a different type of heat exchanger. Comparing the corrugated-fin heat exchanger and the fin-and-tube heat exchanger at equal capacity (performance), the corrugated-fin heat exchanger is smaller in height and thickness than the fin-and-tube heat exchanger. When the fanmotor support member 20 is to be locked onto such a small-size corrugated-fin heat exchanger, thesize adjustment section 30 is fitted into thegroove 26 d of the invertedU-shaped locking plate 26, thereby enabling to lock the fanmotor support member 20 onto the corrugated-fin heat exchanger. - The
size adjustment section 30 is made of a resin material and, as illustrated inFIGS. 4 and 5 , formed into a rectangular parallelepiped shape having a horizontally-oriented outer appearance with adownward groove 31 formed at a lower part of thesize adjustment section 30. AU-shaped regulation piece 32, which is elongated in a longitudinal direction of thesize adjustment section 30, is formed on afront surface 30 a of thesize adjustment section 30 on thesupport column section 21 side. When thesize adjustment section 30 is fitted into thegroove 26 d of the invertedU-shaped locking plate 26 of the fanmotor support member 20, thesupport plate 25 a of the fanmotor support member 20 is fitted into theU-shaped regulation piece 32. - When the
support plate 25 a of the fanmotor support member 20 is fitted into theU-shaped regulation piece 32, lateral movement of thesize adjustment section 30 is regulated byside pieces 32 a formed at both ends of theU-shaped regulation piece 32. Twohook portions 33 protruding rearward are formed at the center of an upper part of arear surface 30 b of thesize adjustment section 30 on an opposite side to theU-shaped regulation piece 32. When thesize adjustment section 30 is fitted into thegroove 26 d of the invertedU-shaped locking plate 26, the twohook portions 33 are caught on the steppedportion 26 c having a flat surface, which is formed on theside surface 26 a of the invertedU-shaped locking plate 26, to thereby temporarily fix thesize adjustment section 30. - Further, at an upper part of the
size adjustment section 30, a plurality of protrudingpieces 34 are arranged in the longitudinal direction of thesize adjustment section 30. Vertical movement of thesize adjustment section 30 fitted into thegroove 26 d of the invertedU-shaped locking plate 26 is regulated by the protrudingpieces 34 and the twohook portions 33. That is, thesize adjustment section 30 is prevented from dropping off the invertedU-shaped locking plate 26. As illustrated inFIG. 7 , a cushioningmember 40 is fitted into thegroove 31 of thesize adjustment section 30. The cushioningmember 40 is provided so as to mitigate vibrations during conveyance and operation of theoutdoor unit 50. - Next, referring to
FIGS. 8 to 11 , description is given of a procedure of mounting the fanmotor support member 20 in a case where theheat exchanger 11 mounted inside theoutdoor unit 50 is the corrugated-fin heat exchanger. -
FIG. 8 is a perspective view of a state before the size adjustment section is mounted on the inverted U-shaped locking plate of the fan motor support member.FIG. 9 is a perspective view of a state after the size adjustment section and the cushioning member are mounted on the inverted U-shaped locking plate of the fan motor support member.FIG. 10 is a perspective view of a state in which the inverted U-shaped locking plate of the fan motor support member is locked onto the heat exchanger through intermediation of the size adjustment section and the cushioning member.FIG. 11 is a perspective view of a state in which the fan motor support member locked onto the heat exchanger is fixed to the bottom panel of the housing. - First, the cushioning
member 40 is fitted into thegroove 31 of thesize adjustment section 30. Under a state in which thegroove 31 into which the cushioningmember 40 is fitted is oriented downward (seeFIG. 8 ), thesize adjustment section 30 is then inserted from the bottom into thegroove 26 d of the invertedU-shaped locking plate 26 of the fan motor support member 20 (seeFIG. 9 ). At this time, the twohook portions 33 are fitted into thegroove 26 d of the invertedU-shaped locking plate 26 along with the insertion of thesize adjustment section 30. When the twohook portions 33 reach the steppedportion 26 c formed on the invertedU-shaped locking plate 26, the twohook portions 33 project toward the steppedportion 26 c side due to an elastic force so that the twohook portions 33 are caught on the steppedportion 26 c. - At this time, the protruding
pieces 34 of thesize adjustment section 30 are brought into contact with an upper surface of the invertedU-shaped locking plate 26 on an inner side thereof, and thesupport plate 25 a of the fanmotor support member 20 is fitted into theU-shaped regulation piece 32 of thesize adjustment section 30, to thereby fix thesize adjustment section 30. In this case, the lateral movement of thesize adjustment section 30 is regulated by theside pieces 32 a formed on both sides of theU-shaped regulation piece 32. - The fan
motor support member 20 is locked onto an upper end portion of the heat exchanger 11 (corrugated-fin heat exchanger) through intermediation of thesize adjustment section 30 fixed to the inverted U-shaped locking plate 26 (seeFIG. 10 ). In this case, the upper end portion of theheat exchanger 11 is fitted into thegroove 31 of thesize adjustment section 30. After that, as described above, the supportcolumn fixing sections 23 of the fanmotor support member 20 are fixed onto theconvex drawing portion 4 a formed on thebottom panel 4 by fastening thescrews 27 through the burringportions 4 b formed on the bottom panel 4 (seeFIG. 11 ). - Incidentally, in a case where only the inverted
U-shaped locking plate 26 is used without using thesize adjustment section 30 and made of a sheet metal material, screw holes need to be formed so as to fix the invertedU-shaped locking plate 26 to thesupport plate 25 a, with the result that the current shape of the mold for the fanmotor support member 20 needs to be modified. Also in a case where only the invertedU-shaped locking plate 26 is used without using thesize adjustment section 30 and made of a resin material, the mold for the fanmotor support member 20 needs to be modified. Further, the coupling portion between the sheet metal material and the resin material may be damaged due to stress concentration caused by the vibrations applied during the conveyance and operation of theoutdoor unit 50. In this respect, Embodiment provides such structure that thesize adjustment section 30 made of a resin material is held by fitting into the invertedU-shaped locking plate 26 of the fanmotor support member 20 without modifying the existing mold for the fanmotor support member 20. Therefore, the range of fitting between thesize adjustment section 30 and the fanmotor support member 20 is wider, thereby enabling to disperse the stress to be applied to thesize adjustment section 30 made of a resin material. - Further, in the
outdoor unit 50 in which the fin-and-tube heat exchanger that is larger in height and thickness is mounted as theheat exchanger 11 arranged perpendicularly to thebottom panel 4, there is no need to use thesize adjustment section 30, and hence only a minimum necessary gap is formed between the fin-and-tube heat exchanger and the top panel 3. On the other hand, in a case where the corrugated-fin heat exchanger is mounted with use of thesize adjustment section 30 in this Embodiment, the corrugated-fin heat exchanger has such specifications that the corrugated-fin heat exchanger is smaller in height and thickness than the fin-and-tube heat exchanger and a gap is therefore formed between the corrugated-fin heat exchanger and the top panel 3 under a state in which the fanmotor support member 20 having thesize adjustment section 30 mounted thereon is locked onto the corrugated-fin heat exchanger. However, the above-mentioned specifications do not raise any problem from the viewpoint of performance and structural strength of theoutdoor unit 50. Thus, there is no need to insert a spacer or the like between the corrugated-fin heat exchanger and the top panel 3 so as to fill the gap generated due to the height difference caused by the difference in specifications between the corrugated-fin heat exchanger and the fin-and-tube heat exchanger. - As described above, according to Embodiment of the present invention, in the case where the fan
motor support member 20 compatible with the fin-and-tube heat exchanger is used for the corrugated-fin heat exchanger that is smaller in height and thickness than the fin-and-tube heat exchanger, thesize adjustment section 30 only needs to be fitted into thegroove 26 d of the invertedU-shaped locking plate 26 formed on the fanmotor support member 20, thereby enabling to lock the fanmotor support member 20 onto the corrugated-fin heat exchanger. In this manner, even for the different types of heat exchangers, the use of thesize adjustment section 30 alone allows the use of the fan motor support member without changing the structure thereof. Therefore, the increase in number of components can be minimized, thereby facilitating the management of inventory and distribution. As a result, materials can be saved. - 1
