Summary of Invention

Technical Problem

[0004]  In the related-art outdoor unit, a plurality of motor support members are required depending on the height and thickness of the heat exchanger, thereby being necessary to prepare the same number of molds for forming the respective motor support members. As a result, the manufacturing cost is increased. Further, the number of components is also increased, thereby causing a problem in that the management of inventory and distribution is cumbersome.

[0005] The present invention has been made to solve the problem described above, and it is therefore an object of the present invention to provide an outdoor unit for an air-conditioning apparatus, which is compatible with a plurality of types of heat exchangers by mounting another component on the structure of a motor support member so as to share the motor support member among the plurality of types of heat exchangers.

Solution to Problem

[0006] According to the present invention, there is provided an outdoor unit for an air-conditioning apparatus, comprising:a housing having an opening formed in a rear surface thereof and an air outlet formed in a front surface thereof; a heat exchanger covering the opening of the rear surface of the housing from an inside of the housing; a fan motor support member having an air-sending device fixed to a center portion thereof, an upper end part of the fan motor support member above the air-sending device having a locking section formed with a downward groove, and a lower end part of the fan motor support member below the air-sending device being fixed onto a bottom panel of the housing; furthermore comprising an adjustment section which has a downward groove, wherein the size adjustment section is fitted into the downward groove of the locking section of the motor support member in accordance with a height and a thickness of the heat exchanger and the upper end of the heat exchanger is fitted into the downward groove of the size adjustment section fitted into the downward groove of the locking section.

Advantageous Effects of Invention

[0007] According to Embodiment of the present invention, when the fan motor support member is to be locked in accordance with the height and thickness of the heat exchanger, the size adjustment section is fitted into the groove of the locking section of the fan motor support member, to thereby lock the fan motor support member onto the upper end portion of the heat exchanger. In this manner, the use of the size adjustment section 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.

Description of Embodiment

[0009] Now, an outdoor unit for an air-conditioning apparatus according to Embodiment of the present invention is described in detail with reference to the drawings. Note that, the present invention is not limited to Embodiment described below but is defined by the appending claims.

[0010] 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 in Fig. 1.

[0011] In Figs. 1 and 2, an outdoor unit 50 according to Embodiment includes a housing 51 formed of an L-shaped front panel 1, a side panel 2, a top panel 3, and a bottom panel 4. In the front panel 1, an air outlet 1a is formed into a circular shape, and is covered with a fan guard 1b. On the side panel 2, a service cover 5 and a valve cover 6 are mounted in a freely removable manner. On a lower surface of the bottom panel 4, foot sections 7 are mounted so as to fix the outdoor unit 50 onto an installation surface. The inside of the outdoor unit 50 is partitioned by a dogleg-shaped separator 8 into an air-sending device chamber 9 and a machine chamber 10.

[0012] An L-shaped heat exchanger 11 and an air-sending device 12 arranged in front of the heat 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 the heat exchanger 11. The air-sending device 12 includes a fan motor 12a fixed to a fan motor support member 20 described later, and a propeller fan 12b.

[0013] When the propeller fan 12b is rotated through drive of the fan motor 12a, air (outdoor air) is sucked through the rotation of the propeller fan 12b to pass through the heat exchanger 11 and flow into the outdoor unit 50. Then, the air is caused to pass through the propeller fan 12b, and is blown outside from the air outlet 1a of the front panel 1 through the fan guard 1b. Thus, during, for example, cooling operation, refrigerant inside the heat exchanger 11 is cooled by the air, and the air caused to pass through the heat exchanger 11 is heated into warm air through the heat exchange between the air and the refrigerant.

[0014] A compressor 14 mounted on the bottom 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 the compressor 14 and the air-sending device 12, and the like are housed in the machine chamber 10.

[0015] Next, the structure of the above-mentioned fan motor support member 20 is described with reference to Figs. 3 to 6.

[0016] 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 in Fig. 2. Fig. 4 is a perspective view of a size adjustment section to be used for the fan motor support member of Fig. 2 as seen from the front side obliquely. Fig. 5 is a perspective view of the size adjustment section of Fig. 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 of Fig. 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 of Fig. 3 as seen from the bottom side obliquely.

[0017] The fan motor support member 20 is mounted in front of the heat exchanger 11. The fan motor support member 20 includes a ladder-shaped support column section 21, a holding section 22 for the air-sending device 12, which is arranged at a center portion of the support column section 21, support column fixing sections 23 each arranged at a lower end portion of the support column section 21, a plate-shaped top panel support section 24 extending horizontally from an upper end portion of the support column section 21 toward the air-sending device 12 side, and a lock and support section 25 extending horizontally from the upper end portion of the support column section 21 toward an opposite side to the top panel support section 24.

[0018] The support column fixing sections 23 are arranged at the front and rear of the support column section 21, and are fixed onto a convex drawing portion 4a formed on the bottom panel 4 by fastening screws 27 obliquely through burring portions 4b formed on the bottom panel 4 (see Fig. 11). As illustrated in Figs. 3 and 6, the lock and support section 25 includes a support plate 25a extending horizontally from the upper end portion of the support column section 21, and an inverted U-shaped locking plate 26 (locking section) formed at a distal end of the support plate 25a with a downward groove 26d. As illustrated in Fig. 6, on one side surface 26a forming the groove 26d of the inverted U-shaped locking plate 26, a stepped portion 26c having a flat surface is formed by bending a cut-and-raised piece 26b upward at a right angle. The cut-and-raised piece 26b is formed by cutting and raising a part of the center of the side surface 26a outward.

[0019] 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 the groove 26d of the inverted U-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 the groove 26d of the inverted U-shaped locking plate 26, thereby enabling to lock the fan motor support member 20 onto the fin-and-tube heat exchanger.

[0020] A size adjustment section 30 is fitted into the groove 26d of the inverted U-shaped locking plate 26 of the lock and support section 25. The size adjustment section 30 is provided so that the fan motor 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 fan motor support member 20 is to be locked onto such a small-size corrugated-fin heat exchanger, the size adjustment section 30 is fitted into the groove 26d of the inverted U-shaped locking plate 26, thereby enabling to lock the fan motor support member 20 onto the corrugated-fin heat exchanger.

[0021] The size adjustment section 30 is made of a resin material and, as illustrated in Figs. 4 and 5, formed into a rectangular parallelepiped shape having a horizontally-oriented outer appearance with a downward groove 31 formed at a lower part of the size adjustment section 30. A U-shaped regulation piece 32, which is elongated in a longitudinal direction of the size adjustment section 30, is formed on a front surface 30a of the size adjustment section 30 on the support column section 21 side. When the size adjustment section 30 is fitted into the groove 26d of the inverted U-shaped locking plate 26 of the fan motor support member 20, the support plate 25a of the fan motor support member 20 is fitted into the U-shaped regulation piece 32.

[0022] When the support plate 25a of the fan motor support member 20 is fitted into the U-shaped regulation piece 32, lateral movement of the size adjustment section 30 is regulated by side pieces 32a formed at both ends of the U-shaped regulation piece 32. Two hook portions 33 protruding rearward are formed at the center of an upper part of a rear surface 30b of the size adjustment section 30 on an opposite side to the U-shaped regulation piece 32. When the size adjustment section 30 is fitted into the groove 26d of the inverted U-shaped locking plate 26, the two hook portions 33 are caught on the stepped portion 26c having a flat surface, which is formed on the side surface 26a of the inverted U-shaped locking plate 26, to thereby temporarily fix the size adjustment section 30.

[0023] Further, at an upper part of the size adjustment section 30, a plurality of protruding pieces 34 are arranged in the longitudinal direction of the size adjustment section 30. Vertical movement of the size adjustment section 30 fitted into the groove 26d of the inverted U-shaped locking plate 26 is regulated by the protruding pieces 34 and the two hook portions 33. That is, the size adjustment section 30 is prevented from dropping off the inverted U-shaped locking plate 26. As illustrated in Fig. 7, a cushioning member 40 is fitted into the groove 31 of the size adjustment section 30. The cushioning member 40 is provided so as to mitigate vibrations during conveyance and operation of the outdoor unit 50.

[0024] Next, referring to Figs. 8 to 11, description is given of a procedure of mounting the fan motor support member 20 in a case where the heat exchanger 11 mounted inside the outdoor unit 50 is the corrugated-fin heat exchanger.

[0025] 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.

[0026]  First, the cushioning member 40 is fitted into the groove 31 of the size adjustment section 30. Under a state in which the groove 31 into which the cushioning member 40 is fitted is oriented downward (see Fig. 8), the size adjustment section 30 is then inserted from the bottom into the groove 26d of the inverted U-shaped locking plate 26 of the fan motor support member 20 (see Fig. 9). At this time, the two hook portions 33 are fitted into the groove 26d of the inverted U-shaped locking plate 26 along with the insertion of the size adjustment section 30. When the two hook portions 33 reach the stepped portion 26c formed on the inverted U-shaped locking plate 26, the two hook portions 33 project toward the stepped portion 26c side due to an elastic force so that the two hook portions 33 are caught on the stepped portion 26c.

[0027] At this time, the protruding pieces 34 of the size adjustment section 30 are brought into contact with an upper surface of the inverted U-shaped locking plate 26 on an inner side thereof, and the support plate 25a of the fan motor support member 20 is fitted into the U-shaped regulation piece 32 of the size adjustment section 30, to thereby fix the size adjustment section 30. In this case, the lateral movement of the size adjustment section 30 is regulated by the side pieces 32a formed on both sides of the U-shaped regulation piece 32.

[0028] 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 the size adjustment section 30 fixed to the inverted U-shaped locking plate 26 (see Fig. 10). In this case, the upper end portion of the heat exchanger 11 is fitted into the groove 31 of the size adjustment section 30. After that, as described above, the support column fixing sections 23 of the fan motor support member 20 are fixed onto the convex drawing portion 4a formed on the bottom panel 4 by fastening the screws 27 through the burring portions 4b formed on the bottom panel 4 (see Fig. 11).

[0029] Incidentally, in a case where only the inverted U-shaped locking plate 26 is used without using the size adjustment section 30 and made of a sheet metal material, screw holes need to be formed so as to fix the inverted U-shaped locking plate 26 to the support plate 25a, with the result that the current shape of the mold for the fan motor support member 20 needs to be modified. Also in a case where only the inverted U-shaped locking plate 26 is used without using the size adjustment section 30 and made of a resin material, the mold for the fan motor 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 the outdoor unit 50. In this respect, Embodiment provides such structure that the size adjustment section 30 made of a resin material is held by fitting into the inverted U-shaped locking plate 26 of the fan motor support member 20 without modifying the existing mold for the fan motor support member 20. Therefore, the range of fitting between the size adjustment section 30 and the fan motor support member 20 is wider, thereby enabling to disperse the stress to be applied to the size adjustment section 30 made of a resin material.

[0030] Further, in the outdoor unit 50 in which the fin-and-tube heat exchanger that is larger in height and thickness is mounted as the heat exchanger 11 arranged perpendicularly to the bottom panel 4, there is no need to use the size 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 the size 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 fan motor support member 20 having the size 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 the outdoor 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.

[0031] 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, the size adjustment section 30 only needs to be fitted into the groove 26d of the inverted U-shaped locking plate 26 formed on the fan motor support member 20, thereby enabling to lock the fan motor support member 20 onto the corrugated-fin heat exchanger. In this manner, even for the different types of heat exchangers, the use of the size 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.
