Definitions

  • the present invention relates to an outdoor unit for an air-conditioning apparatus, including a motor support member for fixing a motor of an air-sending device.
  • an outdoor unit including a motor support member having a locking section with a downward groove in which an upper end portion of a heat exchanger is to be fitted and locked (see, for example, Patent Literature 1).
  • a clamp stand with a downward groove for heat exchangers is disclosed in Patent Literature 2.
  • the downward groove may be adjusted by an engaging claw to heat exchangers having different widths.
  • 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.
  • the manufacturing cost is increased.
  • the number of components is also increased, thereby causing a problem in that the management of inventory and distribution is cumbersome.
  • 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.
  • 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.
  • the size adjustment section 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.
  • 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.
  • 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 .

  • 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 ).
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the cushioning member 40 is fitted into the groove 31 of the size adjustment section 30.
  • 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 ).
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 ).
  • the upper end portion of the heat exchanger 11 is fitted into the groove 31 of the size adjustment section 30.
  • 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.
  • 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.
  • 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.
  • the above-mentioned specifications do not raise any problem from the viewpoint of performance and structural strength of the outdoor unit 50.
  • 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.
  • 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.
