  An air outlet 7b1 provided with a fan guard is formed in the apparatus front surface portion 7b of the casing 7.

  In addition, as for the casing 7, the apparatus side part 7a and the apparatus front surface part 7b may be comprised by another component.

  The outdoor unit 100 of the air conditioner constitutes a device-opposite side surface portion opposite to the device side surface portion 7a of the casing 7, and a column portion to which the side end portion 11a of the long side portion 11 of the heat exchanger 10 is fixed. 8 is provided. The column 8 is an L-shaped cover that bends and connects a part of the back of the apparatus and the side surface opposite to the apparatus.

  FIG. 2 is a perspective view showing the outdoor unit 100 of the air-conditioning apparatus according to the embodiment of the present invention as viewed from the back of the apparatus. As shown in FIG. 2, the outdoor unit 100 of the air conditioner allows the outside air of the outdoor unit 100 to pass through the heat exchanger 10 from the portion covered with the device rear surface and the device side surface portion 7 a of the casing 7 by the blower 4. The outdoor unit 100 is circulated through the air outlet 7b1 on the front side of the apparatus. For this reason, the part covered with the apparatus back surface and the apparatus side surface part 7a of the casing 7 constitutes the inflow surface part. Further, a portion facing the inside of the outdoor unit 100 constitutes an outflow surface portion. In the heat exchanger 10, air flows in the ventilation direction from the inflow surface portion to the outflow surface portion.

  After installation, the outdoor unit 100 of the air conditioner is exposed as a back side opening of the suction port, with the long side portion 11 of the heat exchanger 10 that cannot be easily touched by the user because the wall surface of the house, etc. is directly behind. I am letting. As a result, the rear surface of the apparatus has no outer parts such as a frame that obstructs the flow of air, and air blowing efficiency is good.

  Moreover, since the outdoor unit 100 of the air conditioner can touch the side surface side of the outdoor unit 100 in which the short side part 12 of the heat exchanger 10 exists, the user can easily touch the side surface side 7a of the casing 7. cover. The apparatus side surface portion 7a of the casing 7 is formed with a plurality of openings 7a1 that can be ventilated to serve as suction ports.

  Moreover, as shown in FIG. 2, the heat exchanger 10 is configured by stacking two heat exchanger units 10a and 10b that are vertically stacked.

  Note that a plurality of heat exchanger units may be stacked up and down to constitute a heat exchanger.

Further, as shown in FIG. 2, the side end portion 11 a of the long side portion 11 of the heat exchanger 10 is fixed to the column portion 8 with screws 20 a and 20 b at a plurality of locations. Screw fixing at a plurality of locations fixes each of the two heat exchanger units 10a and 10b that overlap one above the other.
Here, the short side 12 side of the heat exchanger 10 is not fixed to a set location by screwing or a hooking member. The short side 12 side of the heat exchanger 10 is pressed and fixed to the bottom plate 1 by a top plate 9.

  FIG. 3 is an exploded perspective view showing the heat exchanger 10 mounted on the outdoor unit 100 of the air-conditioning apparatus according to the embodiment of the present invention. As shown in FIG. 3, each of the two heat exchanger units 10 a and 10 b that are vertically stacked has a plurality of metal pipes 14 such as copper or aluminum that are processed into a U shape. In addition, each of the two heat exchanger units 10a and 10b that are vertically overlapped is provided with a plurality of metal plates 15 such as aluminum having holes through which the plurality of metal pipes 14 are provided at intervals. Each of the two heat exchanger units 10a and 10b that overlap in the vertical direction is configured by closely processing a plurality of metal pipes 14 and a plurality of metal plates 15.

  Each of the two heat exchanger units 10 a and 10 b that overlap vertically is formed in an L shape in which the short side portion 12 is connected to the long side portion 11 via the corner portion 13. The two heat exchanger units 10a and 10b that overlap in the vertical direction have different heights, but have an L shape having a deviation in the ventilation direction such as a shape error due to manufacturing variation. The deviation in the ventilation direction is largely due to manufacturing variations in the bending R dimension that occur during the bending process.

  In each of the two heat exchanger units 10 a and 10 b that overlap vertically, a plurality of metal pipes 14 are connected to the connection pipe 3 of the outdoor unit 100 at the side end portion 11 a of the long side portion 11.

  Each of the two heat exchanger units 10a and 10b that overlap vertically has an end surface in which a plurality of metal pipes 14 make a U-turn and a U-turn portion 16 is provided at the side end portion 12a of the short side portion 12. .

  The heat exchanger 10 includes a first regulating member 30 that regulates the relative positions of the heat exchanger units 10a and 10b adjacent in the vertical direction.

  The heat exchanger 10 includes a second restricting member 40 that restricts the relative positions of the heat exchanger units 10a and 10b adjacent in the vertical direction.

  The heat exchanger 10 includes a third restricting member 50 that restricts the relative positions of the heat exchanger units 10a and 10b adjacent in the vertical direction.

  FIG. 4 is a perspective view showing the first regulating member 30 according to the embodiment of the present invention. As shown in FIG. 4, the first regulating member 30 includes a heat exchanger unit 10 a that is vertically adjacent between a part of the long side part 11 and a part of the corner part 13 continuous from the long side part 11. The inflow surface portion and the outflow surface portion in the ventilation direction of 10b are sandwiched and regulated. The first restricting member 30 is in contact with a part of the long side part 11 and a part continuing to the long side part 11 of the corner part 13, but is part of the short side part 12 and the short side part 12 of the corner part 13. It does not touch a continuous part. The first regulating member 30 is made of metal.

  The first regulating member 30 is provided with two ribs 31 and 32 that sandwich and regulate the inflow surface portion and the outflow surface portion in the ventilation direction of the upper heat exchanger unit 10a. The two ribs 31 and 32 protrude upward from the base portion 33 sandwiched between the heat exchanger units 10a and 10b adjacent in the vertical direction. The rib 32 in contact with the outflow surface portion is provided with a bent portion 32a having an upper tip having a wider angle so that the upper heat exchanger unit 10a can be smoothly inserted.

  The base portion 33 of the first regulating member 30 is formed with a plurality of drain water passage holes 34 through which dew generated in the upper heat exchanger unit 10a flows downward as drain water.

  The first regulating member 30 is provided with two ribs 35 and 36 that sandwich and regulate the inflow surface portion and the outflow surface portion in the ventilation direction of the lower heat exchanger unit 10b. The two ribs 35 and 36 protrude downward from the base portion 33 sandwiched between the heat exchanger units 10a and 10b adjacent in the vertical direction. The rib 36 in contact with the outflow surface portion is provided with a bent portion 36a having a lower tip angle widened so that the lower heat exchanger unit 10b can be smoothly inserted.

  The two ribs 31 and 35 that come into contact with the inflow surface portion are cut out from one plate-like member and bent from the base portion 33 in the vertical direction. In the rib 31, a hole 31 a is formed by cutting out the rib 35. The two ribs 32 and 36 that come into contact with the outflow surface portion are cut out from one plate-like member and bent from the base portion in the vertical direction. As a result, the four ribs 31, 32, 35, and 36 carry out the regulation of the heat exchanger units 10a and 10b adjacent to each other with less material.

  The 1st control member 30 has the convex part 37 inserted between the adjacent metal plates 15 of the upper heat exchanger unit 10a among the heat exchanger units 10a and 10b adjacent vertically. The convex portion 37 is inserted between the metal plates 15 at the long side portion 11 of the upper heat exchanger unit 10a. Thereby, the convex part 37 has prevented the position shift of the 1st control member 30 in the horizontal direction. For this reason, the 1st control member 30 becomes movable to the left-right direction which is the longitudinal direction of the long side part 11 with the upper heat exchanger unit 10a.

  Here, when the convex portion is also provided in the lower heat exchanger unit 10b, the deformation of the plurality of metal plates 15 of the heat exchanger 10 due to an external impact, or two heat exchanges that overlap vertically due to the impact. There arises a problem such that the container units 10a and 10b are fixed while being shifted left and right. By providing the convex portion 37 only on the upper heat exchanger unit 10a as in the embodiment, the first regulating member 30 moves together with the upper heat exchanger unit 10a even when an impact occurs, It does not move together with the side heat exchanger unit 10b. Therefore, the deformation of the metal plate 15 can be suppressed and the original position can be returned after the impact, and the displacement in the left-right direction, which is the longitudinal direction of the long side portion 11, can be suppressed.

  In the embodiment, the convex portion is inserted between adjacent metal plates of the upper heat exchanger unit. However, the convex portion may be inserted between adjacent metal plates of the lower heat exchanger unit instead of the upper heat exchanger unit.

  FIG. 5 is a diagram showing a range regulated by the first regulating member 30 according to the embodiment of the present invention. As shown in FIG. 5, the first regulating member 30 has a start point 30 a at a part of the long side portion 11 of the heat exchanger 10 indicated by the hatched portion, and the R curve of the corner portion 13 of the heat exchanger 10. It has an end point 30b at a half position. That is, the first restricting member 30 is a heat exchanger unit that is vertically adjacent between a part of the start point 30a of the long side part 11 and the end point 30b of a half position of the corner part 13 continuing from the long side part 11. The relative positions of 10a and 10b are matched. Thus, the 1st control member 30 does not fix the whole area | region of the corner | angular part 13 of the heat exchanger 10 with four ribs, but is provided in the range to the middle of the corner | angular part 13. FIG. Thereby, the bending R dimension difference (manufacturing variation) generated at the time of the bending process of the two heat exchanger units 10a and 10b that are vertically overlapped can be absorbed, and the deviation in the ventilation direction is shorter than the longer side 11 than the shorter side 12 side. Can be greatly forced. The short side portion 12 shown by a broken line in FIG. 5 represents one of the heat exchanger units 10a and 10b that are displaced in the ventilation direction.

  FIG. 6 is a perspective view showing the second regulating member 40 according to the embodiment of the present invention. As shown in FIG. 6, the second regulating member 40 has a ventilation direction between the heat exchanger units 10 a and 10 b that are vertically adjacent to each other in the middle of the long side portion 11 of the heat exchanger units 10 a and 10 b that are vertically adjacent to each other. The inflow surface portion and the outflow surface portion are sandwiched and regulated. The second restriction member 40 is made of metal.

  The second regulating member 40 is provided with two ribs 41 and 42 that sandwich and regulate the inflow surface portion and the outflow surface portion in the ventilation direction of the upper heat exchanger unit 10a. The two ribs 41 and 42 protrude upward from the base 43 sandwiched between the heat exchanger units 10a and 10b adjacent in the vertical direction. The rib 42 in contact with the outflow surface portion is provided with a bent portion 42a whose upper tip angle is widened so that the upper heat exchanger unit 10a can be smoothly inserted.

  The base 43 of the second restricting member 40 is formed with a plurality of drain water passage holes 44 through which dew generated in the upper heat exchanger unit 10a flows downward as drain water.

  The second regulating member 40 is provided with two ribs 45 and 46 that sandwich and regulate the inflow surface portion and the outflow surface portion in the ventilation direction of the lower heat exchanger unit 10b. The two ribs 45 and 46 protrude downward from the base 43 sandwiched between the heat exchanger units 10a and 10b adjacent in the vertical direction. The rib 46 in contact with the outflow surface portion is provided with a bent portion 46a having a wider angle at the lower end so that the lower heat exchanger unit 10b can be smoothly inserted.

  The two ribs 41 and 45 that come into contact with the inflow surface portion are cut out from one plate-like member and bent from the base portion 43 in the vertical direction. The rib 41 is formed with a hole 41a from which the rib 45 is cut. The two ribs 42 and 46 that come into contact with the outflow surface portion are cut out from one plate-like member and bent from the base portion 43 in the vertical direction. In the rib 46, a hole 46b is formed by cutting out the rib 42. Accordingly, the four ribs 41, 42, 45, 46 perform restriction of the heat exchanger units 10 a, 10 b adjacent in the vertical direction with a small amount of material.

  The 2nd control member 40 has the convex parts 47a and 47b inserted between the adjacent metal plates 15 of the upper heat exchanger unit 10a among the heat exchanger units 10a and 10b adjacent vertically. The convex portions 47a and 47b are inserted between the metal plates 15 at the long side portion 11 of the upper heat exchanger unit 10a. Accordingly, the convex portions 47a and 47b prevent the lateral displacement of the second restricting member 40. For this reason, the 2nd control member 40 becomes movable in the left-right direction which is the longitudinal direction of the long side part 11 with the upper heat exchanger unit 10a.

  Here, when the convex portion is also provided in the lower heat exchanger unit 10b, the deformation of the plurality of metal plates 15 of the heat exchanger 10 due to an external impact, or two heat exchanges that overlap vertically due to the impact. There arises a problem such that the container units 10a and 10b are fixed while being shifted left and right. Although the convex portions 47a and 47b are provided only on the upper heat exchanger unit 10a as in the embodiment, the second restricting member 40 moves together with the upper heat exchanger unit 10a even when an impact occurs. The lower heat exchanger unit 10b does not move together. Therefore, the deformation of the metal plate 15 can be suppressed and the original position can be returned after the impact, and the displacement in the left-right direction, which is the longitudinal direction of the long side portion 11, can be suppressed.

  In the embodiment, the convex portion is inserted between adjacent metal plates of the upper heat exchanger unit. However, the convex portion may be inserted between adjacent metal plates of the lower heat exchanger unit instead of the upper heat exchanger unit.

  FIG. 7 is a perspective view showing the third regulating member 50 according to the embodiment of the present invention. As shown in FIG. 7, the third regulating member 50 includes the heat exchanger units 10 a and 10 b that are vertically adjacent to each other at the side end portion 12 a of the short side 12 in the heat exchanger units 10 a and 10 b that are vertically adjacent to each other. The up-and-down direction is regulated, and the play is allowed to allow the deviation in the ventilation direction.

  The third regulating member 50 is made of resin so that it can be easily deformed. Note that the third restricting member 50 may be made of metal as long as a play that allows a shift in the ventilation direction can be provided.

  The upper three insertion holes 51 and 52 through which the U-turn portion 16 in which the metal pipe 14 makes a U-turn are inserted into the third regulating member 50 at the side end portion 12a of the short side portion 12 of the upper heat exchanger unit 10a. , 53 are provided. Further, the lower three insertions through which the U-turn part 16 in which the metal pipe 14 makes a U-turn are inserted into the third regulating member 50 at the side end 12a of the short side part 12 of the lower heat exchanger unit 10b. Holes 54, 55, and 56 are provided.

  These insertion holes 51, 52, 53, 54, 55, 56 are formed so that the vertical dimension fits the U-turn part 16, and regulates the vertical direction between the heat exchanger units 10 a, 10 b adjacent to each other in the vertical direction. ing. Moreover, these insertion holes 51, 52, 53, 54, 55, 56 are formed wider than the U-turn part 16 in the left-right dimension, and have a play that allows displacement in the ventilation direction.

  The insertion holes 51, 53, 54, 56 on the inflow surface portion side and the outflow surface portion side in the ventilation direction are fixed to some extent while allowing the deviation of the U-turn portion 16, and elastic so that the third restriction member 50 does not come off. Deformed claw portions 51a, 53a, 54a, and 56a are provided. The claw portions 51 a, 53 a, 54 a, and 56 a are provided along the left-right direction of the U-turn portion 16 and urged to the extent that the third regulating member 50 cannot be removed from the U-turn portion 16. One claw portion 51a, 54a is provided on each of the left and right sides of each of the insertion holes 51, 54.

  FIG. 8 is a perspective view showing a state in which the heat exchanger 10 mounted on the outdoor unit 100 of the air-conditioning apparatus according to the embodiment of the present invention is viewed from the back side. As shown in FIG. 8, the two heat exchanger units 10 a and 10 b stacked one above the other have long sides so that a plurality of metal pipes 14 can be connected to the connection pipe 3 at the side end 11 a of the long side 11. The side end portions 11a of the portions 11 are aligned and combined. For this purpose, the first restriction member 30 and the second restriction member 40 align the relative positions of the two heat exchanger units 10 a and 10 b that are vertically overlapped with each other at the long side portion 11. Thereby, the surface of the long side part 11 of the two heat exchanger units 10a and 10b piled up and down becomes the level | planar similarly leveled with the small level | step difference resulting from the shift | offset | difference of a ventilation direction.

  On the other hand, the two heat exchanger units 10 a and 10 b stacked one above the other are firmly fixed using the third regulating member 50 at the side end portion 12 a of the short side portion 12 having the U-turn portion 16 of the metal pipe 14. Instead, the upper heat exchanger unit 10a and the lower heat exchanger unit 10b are provided with a play that allows a deviation in the ventilation direction so that they can move in the left-right direction. In addition, the first regulating member 30 regulates a part of the long side portion 11 of the heat exchanger 10 and the middle of the corner portion 13 continuing from the long side portion 11.

  Thereby, when the heat exchanger units 10a and 10b are stacked one above the other, the step 17 caused by the deviation in the ventilation direction caused by the manufacturing variation is shorter than the long side 11 side of the heat exchanger 10. Largely formed on the 12 side. In the heat exchanger 10, the step 17 caused by the deviation in the ventilation direction is formed largely on the short side 12 side.

  Note that the step is caused by a deviation in the ventilation direction between the heat exchanger units that are vertically overlapped. Therefore, there is no problem even if a step facing downward is generated in addition to the step 17 facing upward shown in FIG. .

  The side surface side of the outdoor unit 100 where the short side portion 12 of the heat exchanger 10 having the step 17 exists is covered with the device side surface portion 7 a of the casing 7.

  FIG. 9 is a perspective view showing a state in which a heat exchanger 210 mounted on an outdoor unit of a conventional air conditioner is viewed from the back side. As shown in FIG. 9, the heat exchanger 210 includes a side end portion 211a of a long side portion 211 having a connection end portion of a metal pipe connected to a connection pipe housed in an outdoor unit, and a U-turn portion of the metal pipe. And the side end portion 212a of the short side portion 212 having the same. Therefore, in the heat exchanger 210, the mating portion of the upper heat exchanger unit 210a and the lower heat exchanger unit 210b is a step caused by a deviation in the ventilation direction from the long side portion 211 to the corner portion 213. 217 occurs.

  In this case, if the long side portion 211 of the heat exchanger 210 is exposed to allow air to flow smoothly, the installation operator or the user can easily touch the step 217. For this reason, inconveniences such as injury due to the step 217, or clothing being caught and damaged. In order to prevent this problem, when a net or the like is provided on the back of the apparatus, the heat exchanger 210 cannot be easily touched. However, the number of parts increases, which is uneconomical.

  Further, two heat exchanger units that overlap the top and bottom of the variation generated during the bending process are performed by simultaneously performing the bending process on the upper heat exchanger unit 210a and the lower heat exchanger unit 210b on the same equipment. 210a and 210b are the same, and the step 217 when stacked is eliminated. However, in that case, there is a problem that the equipment is enlarged or the production place is limited, and the increase in production cannot be accommodated.

  According to the embodiment, the outdoor unit 100 of the air conditioner has a long side portion 11, a short side portion 12, and a corner portion 13 that is bent by connecting the long side portion 11 and the short side portion 12. The heat exchanger 10 in which the two heat exchanger units 10a and 10b are stacked one above the other is provided. The heat exchanger 10 is formed such that a deviation in the ventilation direction generated between the heat exchanger units 10a and 10b adjacent vertically is larger on the short side 12 side than on the long side 11 side.

  According to this configuration, the bending angle of the heat exchanger units 10a and 10b is not adjusted at the time of assembling, and the short side portion 12 causes the deviation in the ventilation direction that occurs between the heat exchanger units 10a and 10b adjacent to each other in the vertical direction. It is assembled so as to be larger on the side. Therefore, it is not necessary to adjust the bending angle of the heat exchanger units 10a and 10b at the time of assembly, and the assembly efficiency can be improved.
