Description
Technical Field
The present invention relates to an outdoor unit of an air conditioning apparatus including a heat exchanger in which a plurality of heat exchanger units are stacked vertically.
Background
Conventionally, in an outdoor unit of an air conditioner, a holding member is interposed in order to stably stack a plurality of heat exchanger units, which are partially bent and have an L shape, a U shape, or the like, in the vertical direction.
A technique of supporting an upper heat exchanger unit side surface and a lower heat exchanger unit side surface by a holding member is disclosed (for example, see patent document 1).
Patent document 1: japanese laid-open patent publication No. 2009-79851
However, in the outdoor unit of the air conditioning apparatus described in patent document 1, the holding member restricts most of the range of the straight portion and the corner portion of the heat exchanger unit, a part of which is bent in an L shape, a U shape, or the like. Therefore, when the angles of the bent heat exchanger units are different and the bent angles do not match with each other in the vertically adjacent heat exchanger units, the bent angles of the heat exchanger units need to be adjusted during assembly, which increases the number of assembly steps and the assembly time, resulting in a problem of assembly efficiency.
In order to improve the assembly efficiency, it is conceivable to enlarge the size of the support portion that restricts the side surface of the heat exchanger unit provided in the holding member and to stack the heat exchanger units having a deviation in the bent angle in the vertical direction while keeping the heat exchanger units in an original state. However, in this case, there are problems that: a step due to a displacement of the vertically stacked heat exchanger units in the ventilation direction is generated at a position such as a back surface of the device where an installation worker or a user contacts the vertically stacked heat exchanger units.

Further, the following configuration is possible: the outdoor unit of the air conditioner includes a third regulating member that regulates a relative position between the heat exchanger units adjacent to each other in the vertical direction, and the third regulating member regulates the vertical direction of the heat exchanger units adjacent to each other in the vertical direction at side end portions of the short side portions of the heat exchanger units adjacent to each other in the vertical direction, and has a play that allows displacement in the ventilation direction.
Further, the following configuration is possible: the heat exchanger exposes the long side portion to become the back surface of the apparatus, and the outdoor unit of the air conditioner includes a casing covering the short side portion of the heat exchanger and having a plurality of openings through which air can pass.
Further, the following configuration is possible: the outdoor unit of the air conditioner includes a top plate that is covered on the casing and presses and fixes the top plate of the heat exchanger from a downward direction.
Further, the following configuration is possible: the heat exchanger unit is formed in an L-shape in which the short side portion is continuous with the long side portion via the corner portion, and the housing includes: a device side surface portion covering the short side portion of the heat exchanger; and a device front surface portion on a side opposite to the exposed long side portion of the heat exchanger which becomes a device back surface, wherein the outdoor unit of the air conditioning device includes a pillar portion which constitutes a device opposite side surface portion on a side opposite to the device side surface portion of the casing, and a side end portion of the long side portion of the heat exchanger is fixed, and the top plate is covered on the casing and the pillar portion, and the heat exchanger is pressed and fixed downward.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that, in the drawings, the same or corresponding structures are denoted by the same reference numerals and are common throughout the specification. The forms of the constituent elements shown throughout the specification are merely examples, and the present invention is not limited to these descriptions.
Provided is an implementation mode.
Fig. 1 is an exploded perspective view illustrating an outdoor unit 100 of an air conditioning apparatus according to an embodiment of the present invention. As shown in fig. 1, an outdoor unit 100 of an air conditioner includes a base plate 1 and a heat exchanger 10 disposed on the base plate 1.
The outdoor unit 100 of the air conditioner includes a compressor 2 and a connection pipe 3 connecting the heat exchanger 10 and the compressor 2.
The outdoor unit 100 of the air conditioner includes: a blower 4 for sending air to the heat exchanger 10; a motor, not shown, for driving the blower 4; and a motor mounting base 5 for fixing the blower 4 and the motor. The motor mount 5 is fixed to the base plate 1, and sandwiches the heat exchanger 10 with the base plate 1. The motor mount 5 is pressed from the top plate 9 by a soft member made of a relatively soft material such as a spacer not shown being attached to the top surface side contacting the top plate 9.
The outdoor unit 100 of the air conditioner includes a control device 6 for controlling the compressor 2, the motor, and the like in a flat plate shape above the compressor 2.
The outdoor unit 100 of the air conditioner includes a casing 7 surrounding and housing various components. The casing 7 has an apparatus side surface portion 7a covering the short side portion 12 of the heat exchanger 10 and an apparatus front surface portion 7b on the opposite side of the exposed long side portion 11 of the heat exchanger 10 which becomes the apparatus rear surface.
A plurality of openings 7a1 that can ventilate and serve as suction ports are formed in the device side surface portion 7a of the housing 7.
An outlet 7b1 provided with a fan shroud is formed in the device front surface portion 7b of the casing 7.
The apparatus side surface portion 7a and the apparatus front surface portion 7b of the housing 7 may be formed of separate members.
The outdoor unit 100 of the air conditioner includes a stay 8, and the stay 8 constitutes an opposite-apparatus-side surface portion opposite to the apparatus-side surface portion 7a of the casing 7, and fixes a side end portion 11a of the long side portion 11 of the heat exchanger 10. The column part 8 is an L-shaped cover that bends and connects a part of the back surface of the device and the side surface part opposite to the device. The compressor 2, the connection pipe 3, and the control device 6 are disposed inside the column part 8. Therefore, the opening portion allowing ventilation is not formed in the column portion 8.
The outdoor unit 100 of the air conditioner includes a top plate 9, and the top plate 9 is covered with the casing 7 and the column portion 8 from above and is pressed and fixed downward so as to sandwich the heat exchanger 10 with the bottom plate 1 via the motor mount 5. The top plate 9 is formed in a shape corresponding to four rectangular side surfaces of the outdoor unit having an outer contour formed by the heat exchanger 10, the casing 7, and the column part 8.
Here, the heat exchanger 10 is provided in an L-shape, and has one long side 11, one short side 12, and a corner 13 that connects and bends the long side 11 and the short side 12. That is, the heat exchanger 10 is formed in an L-shape in which the short side portion 12 is continuous with the long side portion 11 via the corner portion 13.
The heat exchanger 10 is disposed along the outer contour of the outdoor unit 100 with the long side portion 11 exposed to the back of the apparatus.
In the embodiment, an L-shape in which the heat exchanger 10 includes one short side portion 12 will be described as an example. However, the heat exchanger of the present invention may be provided in a U-shape having two short side portions connected to both side end portions of one long side portion via corner portions.
Fig. 2 is a perspective view showing an outdoor unit 100 of an air conditioning apparatus according to an embodiment of the present invention, as viewed from the back of the apparatus. As shown in fig. 2, in the outdoor unit 100 of the air conditioner, the air blower 4 causes the outside air of the outdoor unit 100 to flow from a portion covering the back surface of the unit and the side surface portion 7a of the casing 7 to the discharge port 7b1 on the front surface of the unit of the outdoor unit 100 through the heat exchanger 10. Therefore, the portion covering the back surface of the apparatus and the apparatus side surface portion 7a of the housing 7 constitutes an inflow surface portion. The portion facing the inside of the outdoor unit 100 constitutes an outflow surface portion. In the heat exchanger 10, air flows in a ventilation direction from the inflow surface portion to the outflow surface portion.
The outdoor unit 100 of the air conditioner exposes the long side portion 11 of the heat exchanger 10, which is located right behind the outdoor unit after installation and which is not easily touched by a user, to form a rear side opening portion of the suction port. Thus, no external member such as a frame that obstructs the flow of air is present on the back surface of the device, and the air blowing efficiency is good.
In the outdoor unit 100 of the air conditioner, the side surface side portion 7a of the casing 7 covers the side surface side portion 12a of the outdoor unit 100 where the short side portion 12 of the heat exchanger 10 is present, since a user can easily touch the side surface side portion of the outdoor unit 100. A plurality of openings 7a1 that can ventilate and serve as suction ports are formed in the device side surface portion 7a of the housing 7.
As shown in fig. 2, the heat exchanger 10 is configured by stacking two heat exchanger units 10a and 10b that are stacked one on top of the other.
The heat exchanger unit may be configured by stacking a plurality of heat exchanger units of 3 or more in the vertical direction.
As shown in fig. 2, the side end 11a of the long side portion 11 of the heat exchanger 10 is fixed to the column portion 8 by screwing with screws 20a and 20b at a plurality of positions. The screw fastening at a plurality of locations fixes the two heat exchanger units 10a and 10b that are vertically overlapped.
Here, the short side portion 12 side of the heat exchanger 10 is not fixed to a set position by a screw fastening or a hooking member. The short side portion 12 side of the heat exchanger 10 is pressed and fixed to the bottom plate 1 by the 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, a plurality of U-shaped metal pipes 14 made of copper, aluminum, or the like are stacked on each of the two heat exchanger units 10a and 10b stacked one on top of the other. In addition, a plurality of metal plates 15 made of aluminum or the like having holes through which a plurality of metal pipes 14 pass are disposed at intervals in each of the two heat exchanger units 10a and 10b that are stacked one on top of the other. The two heat exchanger units 10a and 10b stacked one on top of the other are each formed by processing a plurality of metal pipes 14 and a plurality of metal plates 15 in close contact with each other.
The two heat exchanger units 10a and 10b stacked one on top of the other are each formed in an L-shape in which the short side portion 12 is continuous with the long side portion 11 via the corner portion 13. The two heat exchanger units 10a and 10b stacked one on top of the other have different heights, but are formed in an L shape having a deviation in the ventilation direction such as a shape error due to manufacturing variations. The deviation in the ventilation direction is large due to manufacturing variations in the difference in the size of the bending arc generated in the bending step.
In each of the two heat exchanger units 10a and 10b stacked one on top of the other, the plurality of metal pipes 14 are connected to the connection pipe 3 of the outdoor unit 100 at the side end 11a of the long side portion 11.
In each of the two heat exchanger units 10a and 10b stacked one on top of the other, the plurality of metal pipes 14 are U-folded at the side end portion 12a of the short side portion 12 to form an end face provided with a U-folded portion 16.
The heat exchanger 10 includes a first regulating member 30, and the first regulating member 30 regulates a relative position between the heat exchanger units 10a and 10b adjacent to each other in the up-down direction.
The heat exchanger 10 includes a second regulating member 40, and the second regulating member 40 regulates the relative position between the heat exchanger units 10a and 10b adjacent to each other in the up-down direction.
The heat exchanger 10 includes a third regulating member 50, and the third regulating member 50 regulates the relative position between the heat exchanger units 10a and 10b adjacent to each other in the up-down direction.
Fig. 4 is a perspective view illustrating the first regulating member 30 according to the embodiment of the present invention. As shown in fig. 4, the first regulating member 30 regulates the inflow surface portion and the outflow surface portion in the ventilation direction of the heat exchanger units 10a and 10b adjacent to each other in the vertical direction between a part of the long side portion 11 and a part of the corner portion 13 continuous from the long side portion 11. The first regulating member 30 is in contact with a part of the long side portion 11 and a part of the corner portion 13 continuous with the long side portion 11, but is not in contact with a part of the short side portion 12 and a part of the corner portion 13 continuous with the short side portion 12. The first limiting member 30 is made of metal.
The first regulating member 30 is provided with two flanges 31 and 32 that regulate the inflow surface portion and the outflow surface portion in the ventilation direction of the upper heat exchanger unit 10a by sandwiching therebetween. The two flanges 31, 32 protrude upward from a base portion 33 sandwiched between the vertically adjacent heat exchanger units 10a, 10 b. The flange 32 in contact with the outflow surface portion is provided with a bent portion 32a, and the bent portion 32a enlarges the angle of the upper tip so that the upper heat exchanger unit 10a can be smoothly inserted.
A plurality of condensed water passing holes 34 are formed in the base portion 33 of the first regulating member 30, and allow dew generated in the upper heat exchanger unit 10a to flow downward as condensed water.
The first regulating member 30 is provided with two flanges 35 and 36 that regulate the inflow surface portion and the outflow surface portion in the ventilation direction of the lower heat exchanger unit 10b by sandwiching therebetween. The two flanges 35, 36 protrude downward from the base portion 33 sandwiched between the vertically adjacent heat exchanger units 10a, 10 b. The flange 36 in contact with the outflow surface portion is provided with a bent portion 36a, and the bent portion 36a enlarges the angle of the lower tip end so that the lower heat exchanger unit 10b can be smoothly inserted.
The two flanges 31 and 35 contacting the inflow surface portion are cut out from 1 plate-like member and bent upward and downward from the base portion 33. The flange 31 is formed with a through hole 31a formed by cutting the flange 35. The two flanges 32 and 36 contacting the outflow surface portion are cut out from 1 sheet of plate-like member and bent upward and downward from the base portion. With the above configuration, the 4 flanges 31, 32, 35, and 36 can restrict the heat exchanger units 10a and 10b adjacent to each other in the upper and lower direction with a small amount of material.
The first regulating member 30 has a convex portion 37, and the convex portion 37 is inserted between the adjacent metal plates 15 of the upper heat exchanger unit 10a out of the heat exchanger units 10a and 10b adjacent to each other. The convex portion 37 is inserted between the metal plates 15 at the long side portion 11 of the upper heat exchanger unit 10 a. Thereby, the convex portion 37 prevents the lateral position displacement of the first regulating member 30. Therefore, the first regulating member 30 can move in the longitudinal direction of the long side portion 11, i.e., in the left-right direction, together with the upper heat exchanger unit 10 a.
Here, in the case where the convex portion is provided also on the lower heat exchanger unit 10b, the following problem arises: the plurality of metal plates 15 of the heat exchanger 10 are deformed by an external impact, and the two heat exchanger units 10a and 10b stacked in the vertical direction are fixed in a state of being shifted in the horizontal direction by the impact. As in the embodiment, by providing the convex portion 37 only to the upper heat exchanger unit 10a, even when an impact occurs, the first regulating member 30 moves together with the upper heat exchanger unit 10a but does not move together with the lower heat exchanger unit 10 b. Therefore, the metal plate 15 can be returned to the original position after the impact while suppressing the deformation thereof, and the positional deviation 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 without being inserted into the upper heat exchanger unit.
Fig. 5 is a diagram showing a range limited by the first limiting member 30 according to the embodiment of the present invention. As shown in fig. 5, the first restriction member 30 has a start point 30a at a part of the long side portion 11 of the heat exchanger 10 indicated by a diagonal line portion, and an end point 30b at a position half of the arc line of the corner portion 13 of the heat exchanger 10. That is, the first regulating member 30 matches the relative positions of the heat exchanger units 10a and 10b adjacent to each other in the up-down direction between the starting point 30a of a part of the long side portion 11 and the end point 30b of the half position of the corner portion 13 continuing from the long side portion 11. In this way, the first regulating member 30 is provided in a range up to the middle of the corner portion 13, instead of fixing the entire region of the corner portion 13 of the heat exchanger 10 with the 4 flanges. This can absorb the difference in the size of the bending arcs (manufacturing variation) that occurs in the bending process of the two heat exchanger units 10a and 10b that are stacked one on top of the other, and can force the deviation in the ventilation direction to be larger on the short side portion 12 side than on the long side portion 11 side. A short side portion 12 of a broken line shown in fig. 5 indicates one of the heat exchanger units 10a, 10b that is offset in the ventilation direction.
Fig. 6 is a perspective view showing a second regulating member 40 according to the embodiment of the present invention. As shown in fig. 6, the second regulating member 40 regulates the flow of air into and out of the heat exchanger units 10a and 10b adjacent to each other in the vertical direction by sandwiching the flow of air between the heat exchanger units 10a and 10b adjacent to each other in the vertical direction between the long side portions 11. The second limiting member 40 is made of metal.
The second regulating member 40 is provided with two flanges 41 and 42 that regulate the inflow surface portion and the outflow surface portion in the ventilation direction of the upper heat exchanger unit 10a by sandwiching therebetween. The two flanges 41 and 42 protrude upward from a base 43 sandwiched between the vertically adjacent heat exchanger units 10a and 10 b. The flange 42 in contact with the outflow surface portion is provided with a bent portion 42a, and the bent portion 42a enlarges the angle of the upper tip so that the upper heat exchanger unit 10a can be smoothly inserted.
A plurality of condensed water passing holes 44 are formed in the base portion 43 of the second regulating member 40, and allow dew generated in the upper heat exchanger unit 10a to flow downward as condensed water.
The second regulating member 40 is provided with two flanges 45 and 46 that regulate the inflow surface portion and the outflow surface portion in the ventilation direction of the lower heat exchanger unit 10b by sandwiching therebetween. The two flanges 45, 46 project downward from the base portion 43 sandwiched between the vertically adjacent heat exchanger units 10a, 10 b. A bent portion 46a is provided in the flange 46 in contact with the outflow surface portion, and the bent portion 46a enlarges the angle of the lower tip end so that the lower heat exchanger unit 10b can be smoothly inserted.
The two flanges 41 and 45 contacting the inflow surface portion are cut out from 1 sheet of plate-like member and bent upward and downward from the base 43. The flange 41 is formed with a through hole 41a formed by cutting the flange 45. The two flanges 42 and 46 contacting the outflow surface portion are cut out from 1 sheet of plate-like member and bent upward and downward from the base 43. The flange 46 is formed with a through hole 46b formed by cutting the flange 42. With the above configuration, the 4 flanges 41, 42, 45, and 46 can restrict the heat exchanger units 10a and 10b adjacent to each other in the upper and lower direction with a small amount of material.
The second regulating member 40 has convex portions 47a, 47b inserted between the adjacent metal plates 15 of the upper heat exchanger unit 10a out of the heat exchanger units 10a, 10b adjacent to each other. 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 10 a. Thus, the convex portions 47a and 47b prevent the lateral position displacement of the second regulating member 40. Therefore, the second regulating member 40 can move in the longitudinal direction of the long side portion 11, i.e., in the left-right direction, together with the upper heat exchanger unit 10 a.
Here, in the case where the convex portion is provided also on the lower heat exchanger unit 10b, the following problem arises: the plurality of metal plates 15 of the heat exchanger 10 are deformed by an external impact, and the two heat exchanger units 10a and 10b stacked in the vertical direction are fixed in a state of being shifted in the horizontal direction by the impact. As in the embodiment, by providing the convex portions 47a and 47b only on the upper heat exchanger unit 10a, even when an impact occurs, the second regulating member 40 moves together with the upper heat exchanger unit 10a but does not move together with the lower heat exchanger unit 10 b. Therefore, the metal plate 15 can be prevented from being deformed and returned to its original position after the impact, and the long side portion 11 can be prevented from being displaced in the lateral direction, which is the longitudinal direction.
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 not into the upper heat exchanger unit but into the adjacent metal plates of the lower heat exchanger unit.
Fig. 7 is a perspective view showing a third regulating member 50 according to the embodiment of the present invention. As shown in fig. 7, the third regulating member 50 regulates the vertical direction of the heat exchanger units 10a and 10b adjacent to each other in the vertical direction with respect to the side end portion 12a of the short side portion 12 of the heat exchanger units 10a and 10b adjacent to each other in the vertical direction, and has a play that allows misalignment in the ventilation direction.
The third regulating member 50 is made of resin so as to be easily deformed. Further, the third restricting member 50 may be composed of metal as long as it can have a play that allows the offset in the ventilation direction.
The third regulating member 50 is provided with 3 upper insertion holes 51, 52, 53 through which the U-folded portion 16 formed by U-folding the metal pipe 14 is inserted at the side end portion 12a of the short side portion 12 of the upper heat exchanger unit 10 a. The third regulating member 50 is provided with 3 insertion holes 54, 55, and 56 on the lower side through which the U-folded portion 16 formed by U-folding the metal pipe 14 is inserted at the side end portion 12a of the short side portion 12 of the lower heat exchanger unit 10 b.
The insertion holes 51, 52, 53, 54, 55, 56 are formed to have a vertical dimension into which the U-folded portion 16 is fitted, thereby restricting vertical directions of the heat exchanger units 10a, 10b adjacent to each other in the vertical direction. The insertion holes 51, 52, 53, 54, 55, and 56 are formed to have a larger left-right dimension than the U-shaped folded portion 16, and have a play that allows displacement in the ventilation direction.
Further, the insertion holes 51, 53, 54, 56 on the inflow surface side and the outflow surface side in the ventilation direction are provided with claw portions 51a, 53a, 54a, 56a, and the claw portions 51a, 53a, 54a, 56a are elastically deformed so as to allow the U-shaped folded portion 16 to be displaced and to be fixed to some extent so that the third regulating member 50 is not detached. The claw portions 51a, 53a, 54a, 56a are provided along the left-right direction of the U-folded portion 16 so as to bias the third regulating member 50 to such an extent that it does not fall off from the U-folded portion 16. The claw portions 51a, 54a are provided one on each of the right and left sides of the insertion holes 51, 54.
Fig. 8 is a perspective view showing a state in which the heat exchanger 10 of the outdoor unit 100 mounted in the air conditioning apparatus according to the embodiment of the present invention is viewed from the rear surface side. As shown in fig. 8, two heat exchanger units 10a and 10b stacked one on top of the other are assembled so that side end portions 11a of the long side portions 11 are aligned with each other, and a plurality of metal pipes 14 can be connected to the connection pipe 3 at the side end portions 11a of the long side portions 11. Therefore, the first regulating member 30 and the second regulating member 40 are engaged with each other at the long side portion 11 at positions where the two heat exchanger units 10a and 10b overlapped in the vertical direction face each other. Thus, the surfaces of the long side portions 11 of the two heat exchanger units 10a and 10b stacked one on top of the other are flat surfaces having a small step difference due to the deviation in the ventilation direction.
On the other hand, the two heat exchanger units 10a and 10b that are stacked one on top of the other are not firmly fixed to the side end portion 12a of the short side portion 12 having the U-turn portion 16 of the metal pipe 14 by the third regulating member 50, but have a play that allows the displacement in the ventilation direction, so that the upper heat exchanger unit 10a and the lower heat exchanger unit 10b can move in the left-right direction, respectively. The first regulating member 30 regulates a portion of the long side portion 11 of the heat exchanger 10 and a middle portion of the corner portion 13 continuing from the long side portion 11.
Thus, in the case of stacking the heat exchanger units 10a and 10b one on another, the step 17 caused by the deviation in the ventilation direction due to the manufacturing variation is formed to be larger on the short side portion 12 side than on the long side portion 11 side of the heat exchanger 10. In the heat exchanger 10, the step 17 caused by the deviation in the ventilation direction is formed to be large on the short side portion 12 side.
Since the step is caused by a deviation in the ventilation direction between the heat exchanger units stacked one above the other, not only the step 17 directed upward as shown in fig. 8 but also a step directed downward may be generated.
The side surface side of the outdoor unit 100 where the short side portion 12 of the heat exchanger 10 having the step 17 is present is covered by the apparatus side surface portion 7a of the casing 7.
Fig. 9 is a perspective view showing a state where the heat exchanger 210 mounted in an outdoor unit of a conventional air conditioning apparatus is viewed from the rear surface side. As shown in fig. 9, the heat exchanger 210 is configured by aligning both the side end 211a of the long side portion 211 having the connection end of the metal pipe connected to the connection pipe accommodated in the outdoor unit and the side end 212a of the short side portion 212 having the U-turn portion of the metal pipe. Therefore, in the heat exchanger 210, a step 217 due to a deviation in the ventilation direction occurs in the corner portion 213 from the long side portion 211 at the mating portion between the upper heat exchanger unit 210a and the lower heat exchanger unit 210 b.
At this time, if the long side portion 211 of the heat exchanger 210 is exposed to allow smooth ventilation of air, the installation worker or user can easily contact the step 217. Therefore, the step 217 causes troubles such as injury, clothes being caught and broken, and the like. In the case where a mesh or the like is provided on the back surface of the apparatus to cope with such a problem, the mesh or the like cannot easily contact the heat exchanger 210. However, the number of parts increases, which is not economical.
Further, by performing the bending processing of the upper heat exchanger unit 210a and the lower heat exchanger unit 210b simultaneously in the same facility, the variation in the bending processing is made the same in the two heat exchanger units 210a and 210b which are vertically overlapped, and the step 217 in the stacking can be eliminated. However, in this case, the following problems arise: the equipment becomes large in size, or the production site is limited, and the increase in production cannot be coped with.
According to the embodiment, the outdoor unit 100 of the air conditioner includes the heat exchanger 10 in which two heat exchanger units 10a and 10b are stacked vertically, and the two heat exchanger units 10a and 10b have the long side portion 11, the short side portion 12, and the corner portion 13 that connects and bends the long side portion 11 and the short side portion 12. The heat exchanger 10 is formed such that the deviation in the ventilation direction between the heat exchanger units 10a and 10b adjacent to each other in the up-down direction is larger on the short side portion 12 side than on the long side portion 11 side.
According to this structure, it is not necessary to adjust the bending angles of the heat exchanger units 10a and 10b at the time of assembly, and the heat exchanger units 10a and 10b adjacent to each other in the vertical direction are assembled so that the deviation in the ventilation direction is large on the short side portion 12 side. Therefore, it is not necessary to adjust the folding angle of the heat exchanger units 10a and 10b at the time of assembly, and the assembly efficiency can be improved. Further, it is possible to suppress a step difference caused by a deviation in the ventilation direction of the vertically stacked heat exchanger units 10a, 10b at a portion where the long side portion 11 is arranged, such as the back surface of the device where an installation worker or a user contacts the vertically stacked heat exchanger units 10a, 10 b.
Therefore, the installation worker or user cannot easily contact the step caused by the deviation in the ventilation direction of the vertically stacked heat exchanger units 10a and 10b at the portion where the long side portion 11 is disposed, such as the back surface of the apparatus, and the safety is improved. Further, it is possible to suppress a step caused by a deviation in the ventilation direction of the vertically stacked heat exchanger units 10a, 10b at a portion where the long side portion 11, which is brought into contact with the vertically stacked heat exchanger units 10a, 10b by an installation worker or a user and is conspicuous in the appearance of the device, is disposed. Therefore, the outdoor unit 100 of the air conditioner does not give the user a sense of uneasiness of the product trouble caused by the conspicuous step difference.
According to the embodiment, the heat exchanger 10 is configured such that the deviation in the ventilation direction between the heat exchanger units 10a and 10b adjacent to each other in the up-down direction is formed larger on the short side portion 12 side than on the long side portion 11 side by matching the relative positions of the heat exchanger units 10a and 10b adjacent to each other in the up-down direction between a part of the long side portion 11 and a part of the corner portion 13 continuous from the long side portion 11.
According to this configuration, the heat exchanger 10 can force a deviation in the ventilation direction on the long side 11 side to the short side 12 side by matching the relative positions of the heat exchanger units 10a and 10b adjacent in the up-down direction between a part of the long side 11 and a part of the corner 13 continuing from the long side 11. 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 heat exchanger units 10a and 10b adjacent to each other in the vertical direction are assembled so that the deviation in the ventilation direction is large on the short side portion 12 side.
According to the embodiment, the outdoor unit 100 of the air conditioner includes the first regulating member 30 that regulates the relative position between the heat exchanger units 10a and 10b adjacent to each other in the up-down direction. The first regulating member 30 regulates the inflow surface portion and the outflow surface portion in the ventilation direction of the heat exchanger units 10a and 10b adjacent to each other in the vertical direction between a part of the long side portion 11 and a part of the corner portion 13 continuous from the long side portion 11.
According to this configuration, in the heat exchanger 10, the relative positions of the heat exchanger units 10a and 10b adjacent to each other in the up-down direction are adjusted between a part of the long side portion 11 and a part of the corner portion 13 continuous from the long side portion 11 by using the first regulating member 30, and the deviation in the ventilation direction on the long side portion 11 side can be forced to the short side portion 12 side.
According to the embodiment, the first regulating member 30 allows the heat exchanger units 10a and 10b adjacent to each other in the up-down direction to move in the longitudinal direction of the long side portion 11.
According to this configuration, the first regulating member 30 allows the longitudinal movement of the long side portion 11 between the heat exchanger units 10a and 10b adjacent to each other in the vertical direction. Therefore, the heat exchanger 10 can suppress damage such as deformation.
According to the embodiment, the first regulating member 30 has the convex portion 37 inserted between the adjacent metal plates 15 of the heat exchanger unit 10a above one of the vertically adjacent heat exchanger units 10a and 10 b.
According to this configuration, the first regulating member 30 moves together with the heat exchanger unit 10a in which the convex portion 37 is inserted to the upper portion of one of the adjacent metal plates 15. The first regulating member 30 can allow the heat exchanger units 10a and 10b adjacent to each other to move relative to each other.
According to the embodiment, the outdoor unit 100 of the air conditioner includes the second regulating member 40 that regulates the relative position between the heat exchanger units 10a and 10b adjacent to each other in the up-down direction. The second regulating member 40 regulates the inflow surface portion and the outflow surface portion in the ventilation direction of the heat exchanger units 10a and 10b adjacent to each other in the vertical direction by sandwiching the inflow surface portion and the outflow surface portion between the long side portions 11 of the heat exchanger units 10a and 10b adjacent to each other in the vertical direction.
According to this configuration, the heat exchanger 10 can forcibly displace the long side portion 11 in the ventilation direction by matching the relative positions of the heat exchanger units 10a and 10b adjacent to each other in the vertical direction in the middle of the long side portion 11 using the second regulating member 40.
In addition, since the second regulating member 40 and the first regulating member 30 force the displacement in the ventilation direction of the long side portion 11 side to the short side portion 12 side at 2 locations, the step difference caused by the displacement in the ventilation direction of the long side portion 11 can be further reduced.
According to the embodiment, the outdoor unit 100 of the air conditioner includes the third regulating member 50 that regulates the relative position between the heat exchanger units 10a and 10b adjacent to each other in the up-down direction. The third regulating member 50 regulates the vertical direction of the heat exchanger units 10a and 10b adjacent to each other with respect to the side end portion 12a of the short side portion 12 of the heat exchanger units 10a and 10b adjacent to each other, and has a play that allows misalignment in the ventilation direction.
According to this configuration, in the heat exchanger 10, the third regulating member 50 can regulate the vertical direction of the heat exchanger units 10a and 10b adjacent to each other in the vertical direction at the side end portion 12a of the short side portion 12. Therefore, in the heat exchanger 10, the upper and lower spaces between the vertically adjacent heat exchanger units 10a and 10b are not separated from each other at the side end 12a of the short-side portion 12. In addition, the third regulating member 50 has an offset clearance allowed in the ventilation direction of the heat exchanger units 10a, 10b adjacent to each other in the up-down direction. Therefore, the heat exchanger 10 can restrict the vertical direction of the side end portion 12a of the short-side portion 12 while keeping the deviation in the ventilation direction forcibly on the short-side portion 12 side.
According to the embodiment, the heat exchanger 10 has the long side portion 11 exposed to become the apparatus back surface. The outdoor unit 100 of the air conditioner includes a casing 7 covering the short side portion 12 of the heat exchanger 10 and having a plurality of openings 7a1 through which air can flow.
According to this structure, the heat exchanger 10 has the long side portion 11 exposed to become the apparatus back surface. Therefore, it is possible to suppress a step caused by a deviation in the ventilation direction of the vertically stacked heat exchanger units 10a, 10b at the long side portion 11 of the device rear surface exposed to be in contact with the vertically stacked heat exchanger units 10a, 10b by an installation worker or a user.
Therefore, the installation worker or user cannot easily contact the step caused by the displacement in the ventilation direction of the vertically stacked heat exchanger units 10a and 10b at the long side portion 11 exposed as the back surface of the apparatus, and safety can be improved. Further, the long side portion 11 exposed to the back surface of the device where the installation worker or user is visually conspicuous and which comes into contact with the vertically stacked heat exchanger units 10a and 10b can suppress a step caused by a deviation in the ventilation direction of the vertically stacked heat exchanger units 10a and 10 b. Therefore, the outdoor unit 100 of the air conditioner does not give the user a feeling of uneasiness of the product trouble caused by the conspicuous step difference on the back surface of the unit.
The casing 7 covers the short-side portion 12 of the heat exchanger 10, and is formed with a plurality of openings 7a1 through which air can pass. Therefore, the step 17 due to the displacement in the ventilation direction or the displacement formed largely on the short side portion 12 side of the heat exchanger 10 is covered by the housing 7 and hidden. Further, the plurality of openings 7a1 through which air can flow are formed in the case 7, so that a decrease in efficiency of the heat exchanger 10 at the short-side portion 12 can be suppressed.
Therefore, since the short-side portion 12 having a large deviation in the ventilation direction is covered by the case 7, the short-side portion cannot easily come into contact with the step 17 caused by the deviation in the ventilation direction of the vertically stacked heat exchanger units 10a and 10b, and safety can be improved for an installation worker or a user. In the outdoor unit 100 of the air conditioner, the short side portion 12 having a large deviation in the ventilation direction is covered by the casing 7, so that the user does not feel uneasy about a product failure due to the step 17 caused by the deviation in the ventilation direction.
According to the embodiment, the outdoor unit 100 of the air conditioner includes the top plate 9 covering the casing 7 and pressing and fixing the heat exchanger 10 downward.
According to this structure, the top plate 9 is covered on the housing 7 and presses the fixed heat exchanger 10 downward. At this time, the top plate 9 can press and fix the heat exchanger 10 downward via the motor mount 5 to which a soft member such as a spacer is stuck and sandwiched with the bottom plate 1. Therefore, even if the misalignment in the ventilation direction that occurs between the vertically adjacent heat exchanger units 10a, 10b is formed to be large on the short-side portion 12 side, the short-side portion 12 side of the heat exchanger 10 is pressed and fixed by the top plate 9, and therefore the heat exchanger 10 can be firmly fixed in a state in which the misalignment in the ventilation direction is allowed. Accordingly, even if the position of the short side portion 12 changes due to the offset amount, the short side portion 12 of the heat exchanger 10 does not need to be fixed at a predetermined position with certainty by screwing, hooking, or the like, and therefore the number of components can be reduced and the assembly efficiency can be improved.
According to the embodiment, the heat exchanger units 10a and 10b are formed in an L-shape in which the short side portion 12 is continuous with the long side portion 11 via the corner portion 13. The casing 7 has an apparatus side surface portion 7a covering the short side portion 12 of the heat exchanger 10, and an apparatus front surface portion 7b on the opposite side of the exposed long side portion 11 of the heat exchanger 10, which is the apparatus rear surface. The outdoor unit 100 of the air conditioner includes a stay 8, and the stay 8 constitutes an opposite-apparatus-side surface portion opposite to the apparatus-side surface portion 7a of the casing 7, and fixes a side end portion 11a of the long side portion 11 of the heat exchanger 10. The top plate 9 presses and fixes the heat exchanger 10 downward while covering the case 7 and the column part 8.
According to this configuration, the heat exchanger 10 including the heat exchanger units 10a and 10b formed in the L-shape is displaced in the forced draft direction, and the side end portions 11a of the long side portions 11 whose end portions are aligned are fixed to the column portion 8. The top plate 9 covers the case 7 and the column part 8, and presses and fixes the heat exchanger 10 downward. At this time, the top plate 9 can press and fix the heat exchanger 10 downward via the motor mount 5 to which a soft member such as a spacer is stuck and sandwiched with the bottom plate 1. Therefore, even if the misalignment in the ventilation direction that occurs between the vertically adjacent heat exchanger units 10a, 10b is formed to be large on the short-side portion 12 side, the short-side portion 12 side of the heat exchanger 10 is pressed and fixed by the top plate 9, and therefore the heat exchanger 10 can be firmly fixed in a state in which the misalignment in the ventilation direction is allowed. Accordingly, even if the position of the short side portion 12 changes due to the offset amount, the short side portion 12 of the heat exchanger 10 does not need to be fixed at a predetermined position with certainty by screwing, hooking, or the like, and therefore the number of components can be reduced and the assembly efficiency can be improved.
The motor mount 5 is configured such that a soft member made of a soft material such as a spacer is stuck to the top surface side and is in contact with the top plate 9. Thus, the outdoor unit 100 of the air conditioner can prevent the contact sound between the motor mount 5 and the top plate 9 due to vibration during operation.
The heat exchanger units 10a and 10b are formed in an L-shape in which the short side portion 12 is continuous with the long side portion 11 via the corner portion 13. However, the present invention can be applied even if the heat exchanger unit is formed in a U-shape having short side portions on both sides of a long side portion.
