[0008] Patent Document 4: Japanese Patent Application Publication No. 7-217947 Summary of the Invention

[0009] Because outdoor units are relatively heavy, moving them to their designated locations during air conditioning installation is a significant workload. Furthermore, the size of outdoor units makes them difficult to install in small or complex spaces. In such confined spaces, manual operation is required, increasing the workload. These problems have become more pronounced in recent years due to the trend towards larger and heavier outdoor units.

[0010] Therefore, the present invention provides an outdoor unit of an air conditioning device and an air conditioning device that can reduce the workload of configuration even when the device is large or heavy, and can be well configured in limited spaces such as small installation areas or complex layouts.

[0011] An outdoor unit of an air conditioning device according to one aspect of the present invention includes: a first unit having a first refrigerant pipe; and a second unit having a second refrigerant pipe. The first unit and the second unit are configured to be able to be joined and separated from each other. A specific unit including at least one of the first unit and the second unit has at least one joining member configured to be able to join and separate the first refrigerant pipe and the second refrigerant pipe. In addition, the specific unit has a support member that supports the joining member in the joined state of the first unit and the second unit being joined, allowing it to reciprocate between a joined position where the first refrigerant pipe and the second refrigerant pipe are joined by the joining member and a separated position where the first refrigerant pipe and the second refrigerant pipe can be separated.

[0012] One aspect of the present invention relates to an air conditioning device including the outdoor unit of the aforementioned air conditioning device.

[0013] According to one aspect of the present invention, an outdoor unit and an air conditioning device can be provided that can reduce the workload during configuration even when the device is large or heavy, and can be well configured in confined spaces such as spaces with small installation area or complex layouts.

[0022] Hereinafter, an exemplary embodiment of the present invention will be described with reference to the accompanying drawings. Figure 1 This is a block diagram showing the structure of the air conditioning device 1 according to the embodiment. Figure 2 It means Figure 1 The diagram shows the outdoor unit 3 in the combined state of the first unit 4 and the second unit 5.

[0023] like Figure 1 As shown, the air conditioning unit 1 includes an indoor unit 2, an outdoor unit 3, and multiple refrigerant pipes RP1 to RP4 connecting the indoor unit 2 and the outdoor unit 3. The air conditioning unit 1 can be driven (operated) in any of several modes, including cooling mode, heating mode, and dehumidification mode. As detailed later, the outdoor unit 3 includes a first unit 4 and a second unit 5. The first unit 4 and the second unit 5 are configured to be able to be connected and disconnected. Thus, the air conditioning unit 1 is configured to allow for proper configuration of the outdoor unit 3 even when the outdoor unit 3 is larger or heavier.

[0024] The indoor unit 2 of this embodiment includes: an indoor heat exchanger 20 (hereinafter also simply referred to as heat exchanger 20) for exchanging heat between refrigerant and indoor air; and a blower 21 for supplying indoor air to the heat exchanger 20. The blower 21 has a fan 23 and a fan motor FM1 for rotating the fan 23. The indoor unit 2 also includes a temperature sensor S for detecting indoor temperature and an operation unit 22 for users to perform on / off operations or switching operations of the air conditioning device 1, such as switching operating modes.

[0025] The outdoor unit 3 includes: an outdoor heat exchanger 30 (hereinafter also simply referred to as heat exchanger 30) for exchanging heat between the refrigerant and the outside air; a compressor 31 for compressing the refrigerant; a pressure reducing device 32 for reducing the pressure of the refrigerant; and a blower 33 for supplying outside air to the heat exchanger 30. The pressure reducing device 32 includes, for example, a pressure reducing valve. The blower 33 has a fan 38 and a fan motor FM2 for rotating the fan 38. In this embodiment, the fan motors FM1 and FM2 are electric motors. The refrigerant circulates through multiple refrigerant pipes RP1 to PR4 in the heat exchanger 20, heat exchanger 30, compressor 31, and pressure reducing device 32.

[0026] The outdoor unit 3 also includes a switching valve V that switches the flow direction of the refrigerant circulating inside the outdoor unit 3. The switching valve V is, for example, a four-way valve. The outdoor unit 3 may also include various valve devices, filters, etc., as needed. For example, refrigerant pipe RP1 connects the heat exchanger 20 and the pressure reducing device 32. Refrigerant pipe RP2 connects the pressure reducing device 32 and the heat exchanger 30. Refrigerant pipe RP3 connects the heat exchanger 20 and the switching valve V. Refrigerant pipe RP4 connects the heat exchanger 30 and the switching valve V. The outdoor unit 3 of this embodiment has a generally rectangular parallelepiped shape, with its width in the X direction and its width in the Y direction (as opposed to the X-direction). Figure 2 and Figure 3 The direction orthogonal to the paper surface is the depth direction, and the Z direction is the height direction.

[0027] like Figure 1 and Figure 2 As shown, the outdoor unit 3 of this embodiment includes: a first unit 4 having a first housing 36; a second unit 5 having a second housing 37 and configured to be able to be combined with and separated from the first unit 4; and a defined component assembly 35. The component assembly 35 includes a compressor 31, a heat exchanger 30, and a blower 33. As an example, the first housing 36 houses a portion of the components in the component assembly 35, including the heat exchanger 30 and the blower 33. The second housing 37 houses the remaining components in the component assembly 35, including the compressor 31.

[0028] Furthermore, at least one of the first housing 36 and the second housing 37 has an engaging portion 39 that engages with the other housing. When the first housing 36 and the second housing 37 have a pair of engaging portions 39, the pair of engaging portions 39 may be configured, for example, to include: a groove provided in one of the first housing 36 and the second housing 37; and a protrusion provided in the other housing, embedded in the groove, and engaging with the surface of the groove. Furthermore, the outdoor unit 3 of this embodiment also includes a cover 90 that externally covers the connecting member 6 and the support member 7, described later. The cover 90 is detachably mounted to the second unit 5.

[0029] like Figure 1 As shown, the component group 35 of this embodiment includes a plurality of electrical components E housed in each of the first housing 36 and the second housing 37. For example, the electrical component E housed in the second housing 37 includes a compressor 31. The electrical component E housed in the first housing 36 includes a fan motor FM2. Furthermore, for example, the second unit 5 has a power line PL that supplies power from the outside. In this case, the electrical component E housed in the second housing 37 includes a power supply device 34 that supplies power to each electrical component E housed in the first housing 36 and the second housing 37. In the outdoor unit 3, the power supplied from the outside to the power line PL is supplied to each electrical component E via the power supply device 34 of the second unit 5.

[0030] Figure 3 It means Figure 1 The diagram shows the outdoor unit 3 before the first unit 4 and the second unit 5 are combined. Figure 3 In the middle, the following was omitted. Figure 2 The illustration shows cover 90. (As shown) Figure 3 As shown, the first unit 4 has at least one first refrigerant pipe L1, L2. The second unit 5 has at least one second refrigerant pipe M1, M2. When the first unit 4 and the second unit 5 are combined, the first refrigerant pipe L1 is combined with the second refrigerant pipe M1, and the first refrigerant pipe L2 is combined with the second refrigerant pipe M2. In order to reduce the workload of personnel involved in the combination of refrigerant pipes L1, L2, M1, M2, a specific unit including at least one of the first unit 4 and the second unit 5 has at least one connecting member 6 and a supporting member 7 supporting the connecting member 6.

[0031] As an example, the specific unit in this embodiment includes only the second unit 5 of the first unit 4 and the second unit 5. That is, the second unit 5 has both a connecting member 6 and a supporting member 7. The connecting member 6 is configured to connect and disconnect the first refrigerant pipes L1, L2 from the second refrigerant pipes M1, M2. The supporting member 7 supports the connecting member 6 in the connected state of the first unit 4 and the second unit 5, allowing it to reciprocate between two positions (see reference). Figure 7 and Figure 8 The two positions are the joining position P1 where the first refrigerant pipes L1 and L2 and the second refrigerant pipes M1 and M2 are joined by the joining component 6 as described later, and the separation position P2 where the first refrigerant pipes L1 and L2 and the second refrigerant pipes M1 and M2 can be separated.

[0032] Figure 4 It means Figure 3 The diagram shows the structure of the first refrigerant pipes L1 and L2, and the second refrigerant pipes M1 and M2, and their surrounding area. Figure 4 In the diagram, only the ends 11 to 14 of each refrigerant pipe are shown as part of the structure of the first refrigerant pipes L1 and L2 and the second refrigerant pipes M1 and M2. Figure 5 It means Figure 3 The diagram shows a cross-sectional view of the first refrigerant pipes L1 and L2 and the second refrigerant pipes M1 and M2 before they are connected. Figure 6 It means Figure 3 The diagram shows a cross-sectional view of the first refrigerant pipes L1 and L2 and the second refrigerant pipes M1 and M2 immediately after connection. Figure 5 In the middle, the connecting component 6 is positioned at the separation position P2. Figure 6 In the middle, the connecting component 6 is configured at the connecting position P1.

[0033] like Figure 4 As shown, the first unit 4 has two first refrigerant pipes L1 and L2. Furthermore, as an example, at least one connecting member 6 in this embodiment includes two connecting members 6. The second unit 5 of this embodiment has: two second refrigerant pipes M1 and M2; two connecting members 6; and a single support member 7 supporting the two connecting members 6. The two connecting members 6 are respectively inserted through the pipe ends 11 and 12 of the second refrigerant pipes M1 and M2. The two connecting members 6 include a connecting member 6A inserted through pipe end 11 and a connecting member 6B inserted through pipe end 12.

[0034] As an example, two first refrigerant pipes L1 and L2 and two second refrigerant pipes M1 and M2 are arranged in the width direction of the outdoor unit 3. Furthermore, the pipe ends 11 to 14 of each of the refrigerant pipes L1, L2, M1, and M2 extend in the same direction. A support member 7 supports two connecting members 6 from below. The pipe axis X1 of each pipe end 11 and 12 and the pipe axis X2 of each pipe end 13 and 14 are straight. Pipe ends 11 and 12 are parallel to each other, and pipe ends 13 and 14 are also parallel to each other. When the first unit 4 and the second unit 5 are combined, pipe ends 11 and 13 are arranged with their pipe axes X1 and X2 aligned, and pipe ends 12 and 14 are also arranged with their pipe axes X1 and X2 aligned. In this embodiment, the pipe axes X1 and X2 in the combined state are oriented parallel to the vertical direction.

[0035] The following description, using the structures of refrigerant pipes L1, L2, M1, M2 and connecting component 6A as examples, will explain the structures of refrigerant pipes L1, M1 and connecting component 6A. Figure 5 As shown, the first refrigerant pipe L1 includes a first pipe body 15 and a first pipe end 11. The first pipe body 15 extends inside the first unit 4. The first pipe end 11 is installed at the periphery of the opening of the first pipe body 15. The second refrigerant pipe M1 includes a second pipe body 16 and a second pipe end 13. The second pipe body 16 extends inside the second unit 5. The second pipe end 13 is installed at the periphery of the opening of the second pipe body 16.

[0036] The first tube end 11 is tapered, gradually tapering towards the front end of the first refrigerant tube L1. The first tube end 11 has a shape that allows insertion into the second tube end 13. An annular sealing member 17, extending circumferentially along the second tube end 13 and contacting the outer circumferential surface of the first tube end 11, is disposed on the inner circumferential surface of the second tube end 13. Figure 6 As shown, when the first refrigerant pipe L1 and the second refrigerant pipe M1 are connected, the inner circumferential surface of the second pipe end 13 is in contact with the outer circumferential surface of the first pipe end 11. The sealing component 17 prevents refrigerant from leaking from the flow path formed by the first pipe end 11 and the second pipe end 13.

[0037] The second refrigerant pipe M1 also includes a movable body 18 held at the second pipe end 13 in a manner that allows it to move radially within the second pipe end 13. The movable body 18, for example, includes at least one sphere. The second pipe end 13 has a plurality of radially extending passages 19 in which the movable body 18 is disposed. The movable body 18 reciprocates radially within the passages 19 at the second pipe end 13. The connecting member 6 includes a sleeve 60 inserted at the connecting position P1 through the first refrigerant pipe L1 and the second refrigerant pipe M2. The sleeve 60 covers at least a portion of the outer peripheral surface of the second pipe end 13.

[0038] In this embodiment, with the connecting member 6 positioned at the connecting position P1, the first tube end 11 is inserted into the second tube end 13, and the sleeve 60 contacts the movable body 18. Thus, the movable body 18 contacts the first tube end 11 radially from the second tube end 13, and the first tube end 11 and the second tube end 13 are connected. As an example, the first tube end 11 has a groove 11a into which a portion of the movable body 18 is inserted. The groove 11a is disposed on the outer surface of the first tube end 11 and extends circumferentially along the first tube end 11. Furthermore, as... Figure 5 As shown, with the connecting member 6 positioned in the separated position P2, the moving body 18 can be spaced apart from the first tube end 11 radially from the second tube end 13, thereby separating the moving body 18 from the first tube end 11. Thus, the first tube end 11 and the second tube end 13 are separated.

[0039] In this embodiment, the connecting component 6 includes components along the direction from the separation position P2 to the connecting position P1 (in... Figure 5 In the example shown (with the paper facing downwards), a force-applying component 61 applies force to the sleeve 60. The force-applying component 61, as an example, includes a helical spring wound around the outer periphery of the second tube end 13. The force-applying component 61 engages with the sleeve 60 and the second tube end 13. By positioning the connecting component 6 in the separated position P2, the sleeve 60 moves relative to the second tube end 13 against the force applied by the force-applying component 61, and the sleeve 60 can no longer restrict the movement of the moving body 18. Thus, the moving body 18 can be spaced apart from the first tube end 11 radially from the second tube end 13. Alternatively, the moving body 18 may have other shapes, such as an axial shape with the radial direction of the second tube body 16 as its length, that can engage with the second refrigerant tubes M1 and M2. Furthermore, the force-applying component 61 may also include a spring body other than a helical spring. The structures of the connecting component 6A, the first refrigerant tube L1, and the second refrigerant tube M1 have been described above; the structures of the connecting component 6B, the first refrigerant tube L2, and the second refrigerant tube M2 are similar.

[0040] like Figure 4As shown, the support member 7 has a support portion 70 and an operating portion 75. Furthermore, the support member 7 has at least one through hole 71, a shaft portion 72, and a locking portion 73. The support member 7 of this embodiment is a machined product formed by bending a plate member. Thus, the support member 7 simplifies the constituent parts and reduces the number of parts.

[0041] The support portion 70 has a flat plate surface 70a. For example, the plate surface 70a has a rectangular outline extending in a direction orthogonal to the tube axis X2. The support portion 70 supports the connecting member 6 above the plate surface 70a. A through hole 71 is disposed on the support portion 70. The through hole 71 penetrates the support portion 70 in the thickness direction. Either the first refrigerant tubes L1 and L2 and the second refrigerant tubes M1 and M2 (here, the first refrigerant tubes L1 and L2) is inserted into the through hole 71. In this embodiment, at least one through hole 71 includes two through holes 71A and 71B.

[0042] The support portion 70 of this embodiment includes at least one protrusion 74 that protrudes from the plate surface 70a and abuts against the connecting member 6. The at least one protrusion 74 of this embodiment includes a plurality of protrusions 74. The plurality of protrusions 74 have protrusion heights that abut against each of the two connecting members 6A and 6B at different height positions relative to the plate surface 70a.

[0043] As an example, the support portion 70 includes a plurality of protrusions 74A, 74B disposed around the periphery of each of the through holes 71A, 71B. The protrusions 74 are bent portions formed by bending a portion of the aforementioned plate member. In this embodiment, the protrusion 74 has an inclined portion 74C whose end face in the protruding direction slopes downward from the shaft portion 72 toward the operating portion 75. The inclined portion 74C contacts the lower end face of the sleeve 60 of the connecting member 6 in the separated position P2 (see reference). Figure 7 The operating part 75 and the support part 70 are arranged continuously and operated by an operator. In this embodiment, the operating part 75 is located in the outermost part of the support member 7, closest to the outermost part of the second unit 5.

[0044] The shaft portion 72 is connected to the support portion 70 at a distance spaced from the operating portion 75, and extends in a direction parallel to the plate surface 70a. Specifically, in this embodiment, the shaft portion 72 includes a pair of shaft portions 72A and 72B that protrude outwards from both sides of the support portion 70 in the aforementioned direction. The shaft portions 72A and 72B are inserted into the shaft support portion 37A of a specific unit (see reference). Figure 7 As an example, shaft portions 72A and 72B are plate-shaped portions with a rectangular cross-section in a direction orthogonal to the aforementioned direction.

[0045] The locking part 73 is inserted into the retaining part 37B of the specific unit (see reference). Figure 7The retaining portion 73 is connected to the support portion 70 at a distance spaced from the shaft portion 72, and extends in a direction parallel to the plate surface 70a. In this embodiment, the retaining portion 73 includes a pair of retaining portions 73A that protrude outwards from both sides of the support portion 70 in the aforementioned direction. In this embodiment, the shaft portion 72 and the retaining portions 73A extend in the same direction.

[0046] Figure 7 It means Figure 3 The diagram shows the appearance of the support member 7 when the connecting member 6 is in the separated position P2. Figure 8 It means Figure 3 The diagram shows the appearance of the support member 7 when the connecting member 6 is in the connecting position P1. Figure 7 and Figure 8 The cross-section of the support member 7 and the positions of the shaft portion 72 and the locking portion 73A are shown. The specific unit has a shaft support portion 37A and a retaining portion 37B. The shaft support portion 37A supports the shaft portion 72. The retaining portion 37B retains the support member 7 when the locking portion 73 is inserted and the connecting member 6 is in the separated position P2. In this embodiment, the second housing 37 of the second unit 5, which is the specific unit, has a pair of shaft support portions 37A and a pair of retaining portions 37B. The shaft support portions 37A and the retaining portions 37B are the peripheral portions of the through holes of the second housing 37. Each through hole constituting the shaft support portion 37A and the retaining portion 37B, as an example, penetrates the second housing 37 in a parallel direction. An internal space S1 is arranged inside the shaft support portion 37A.

[0047] The retaining part 37B includes: a limiting part 37C, which limits the movement of the locking part 73 associated with the swinging of the supporting part 70 within a certain range; and a releasing part 37D, which is continuous with the limiting part 37C and releases the aforementioned limitation. Figure 8 As shown, viewed from the axial direction (X direction, for example) of the shaft portion 72, an internal space S2 is arranged inside the restricting portion 37C, and an internal space S3 is arranged inside the releasing portion 37D. The internal spaces S2 and S3 extend and communicate in mutually orthogonal directions. In the internal space S2, the locking portion 73 abuts against the portion of the second housing 37 that defines the restricting portion 37C in the X1 and X2 directions (Z direction, for example), thereby holding the connecting member 6 supported by the support member 7 in the separated position P2. Furthermore, because the locking portion 73 is located in the internal space S3 arranged inside the releasing portion 37D, the locking portion 73 can move within a certain range in the internal space S3 along the X1 and X2 directions, thereby allowing the connecting member 6 supported by the support member 7 to move from the separated position P2 to the connected position P1.

[0048] In the outdoor unit 3 of this embodiment, viewed axially from the shaft portion 72, the area of ​​the internal space S1 of the shaft support portion 37A is sufficiently larger than the cross-sectional area of ​​the shaft portion 72, and the total area of ​​the internal spaces S2 and S3 of the retaining portion 37B is sufficiently larger than the cross-sectional area of ​​the locking portion 73. Therefore, by operating the operating unit 75, the operator can move the support portion 70 relative to the shaft support portion 37A while the shaft portion 72 is supported by the shaft support portion 37A. In this embodiment, by operating the operating unit 75, the operator moves the shaft portion 72 within the internal space S1 of the shaft support portion 37A, thereby enabling the locking portion 73 to move within the internal spaces S2 and S3 of the retaining portion 37B.

[0049] In this embodiment, when the operator operates the operating part 75 and pushes it toward the refrigerant pipes L1 and M1 into the interior of the second housing 37, the shaft part 72 moves in the internal space S1 along the pushing direction (here, the Y direction), and the locking part 73 is disposed in the internal space S2 of the limiting part 37C. Thus, the connecting parts 6 (6A, 6B) are simultaneously held in the separated position P2. Figure 7 ).

[0050] Furthermore, when the operator operates the operating part 75 and pulls it out of the second housing 37 in a direction opposite to the pushing direction, the shaft part 72 moves in the internal space S1, and the locking part 73 moves from the internal space S2 to the internal space S3. Thus, the connecting parts 6 (6A, 6B) can simultaneously move from the separation position P2 to the connection position P1. Figure 8 Additionally, in Figure 8 The image shows the locking part 73 moving from the internal space S2 to the internal space S3, and then, through the operation of the operation part 75, moving the locking part 73 to the lower end of the portion of the second housing 37 that defines the release part 37D.

[0051] Next, the operation of the operator when combining the first unit 4 and the second unit 5 will be explained. With the first unit 4 and the second unit 5 separated, the operator operates the operating part 75 of the support member 7, causing the locking part 73 of the support member 7 to be held by the holding part 37B. As a result, the connecting parts 6 (6A, 6B) are simultaneously held in the separated position P2. Figure 7 In this embodiment, multiple refrigerant pipes L1 and L2 are supported by a common support member 7. Therefore, through a single operation of the operating unit 75, all multiple connecting parts 6 (6A, 6B) are simultaneously held in the separated position P2. At this time, in each connecting part 6 (6A, 6B), the sleeve 60 is supported by the protrusion 74 of the support member 7 and moves relative to the second pipe ends 13, 14 against the force applied by the force-applying member 61. Figure 5 ).

[0052] Next, the operator positioned the second unit 5 close to the first unit 4, aligning the ends 11 and 12 of the refrigerant pipes L1 and L2 of the second unit 5 with the ends 13 and 14 of the refrigerant pipes M1 and M2 of the first unit 4 so that the pipe axes X1 and X2 were aligned. Figure 3 Then, the operator inserts pipe end 11 into pipe end 13 and pipe end 12 into pipe end 14. Figure 7 The operator operates the operating unit 75 to move the locking part 73 of the support member 7 from the limiting part 37C of the holding part 37B to the releasing part 37D. Figure 8 At this time, the support member 7 can move relative to the second housing 37.

[0053] Accompanying the aforementioned relative movement of the support member 7, the sleeve 60, which is subjected to force by the force-applying member 61, moves relative to the pipe ends 13 and 14 along the pipe axis X1 and X2 in the direction in which the force-applying member 61 extends. As a result, the sleeve 60 moves to the engagement position P1. The moving body 18 of the pipe ends 13 and 14 moves radially in the pipe ends 13 and 14 and contacts the pipe ends 11 and 12. At this time, a portion of the moving body 18 is embedded in the groove 11a of the pipe ends 11 and 12 (see reference). Figure 6 Thus, refrigerant pipes L1 and M1 are connected, and refrigerant pipes M1 and M2 are connected. In this way, even if the operator does not directly apply external force to the connecting parts 6, the refrigerant pipes L1, L2, M1, and M2 are connected. The operator then installs the cover 90 onto the first unit 4 and the second unit 5 by covering the connecting parts 6 and the support parts 7 from the outside. At this point, the assembly of the outdoor unit 3 is complete.

[0054] Next, the air conditioning unit 1 during operation will be described. In heating mode, the refrigerant vaporizes by exchanging heat with outside air in the heat exchanger 30. The vaporized refrigerant is then transported to the compressor 31 via the refrigerant pipe RP4 and the switching valve V. The compressor 31 compresses the vaporized refrigerant and discharges it. The vaporized refrigerant is then transported to the heat exchanger 20 via the switching valve V and the refrigerant pipe RP3. The heat exchanger 20 allows the vaporized refrigerant to exchange heat with indoor air. The blower 21 delivers the heated air, which has undergone heat exchange with the refrigerant in the heat exchanger 20, to the room. Accompanying this heat exchange, the refrigerant liquefies. The liquefied refrigerant is then transported to the pressure reducing device 32 via the refrigerant pipe RP1. The refrigerant is depressurized by the pressure reducing device 32, becoming a two-phase gas-liquid mixture. The two-phase refrigerant returns to the heat exchanger 30 via the refrigerant pipe RP2.

[0055] Furthermore, in cooling or dehumidifying mode, the refrigerant liquefies by exchanging heat with outside air in heat exchanger 30. The liquefied refrigerant is then transported to pressure reducing device 32 via refrigerant pipe RP2. Pressure reducing device 32 reduces the pressure of the liquefied refrigerant. The liquefied refrigerant is then transported to heat exchanger 20 via refrigerant pipe RP1. Heat exchanger 20 allows the liquefied refrigerant to exchange heat with indoor air. Fan 21 delivers the cooled air, which has undergone heat exchange with the refrigerant in heat exchanger 20, into the room. Accompanying this heat exchange, the refrigerant vaporizes. The vaporized refrigerant is then transported to compressor 31 via refrigerant pipe RP3 and switching valve V. Compressor 31 compresses the vaporized refrigerant and discharges it. The vaporized refrigerant returns to heat exchanger 30 via switching valve V and refrigerant pipe RP4.

[0056] As explained above, the outdoor unit 3 of this embodiment includes a first unit 4 and a second unit 5 for refrigerant circulation, with the first unit 4 and the second unit 5 in a separated state. Therefore, even in situations with a small number of personnel or limited space, each unit 4 and 5 can be moved to a designated location, making it easy to install the outdoor unit 3 in the desired location. That is, even with an increased size or weight, the workload during installation is reduced, and it can be well-configured in confined spaces such as small installation areas or complex layouts. Furthermore, for example, in the combined state of the first unit 4 and the second unit 5, by operating the support member 7 to move the connecting member 6 to the combined position P1 or the separated position P2, the first refrigerant pipes L1, L2 and the second refrigerant pipes M1, M2 can be connected or separated. Therefore, the first unit 4 and the second unit 5 can be easily separated or connected. Therefore, even when the outdoor unit 3 of the air conditioning device 1 is composed of multiple units 4 and 5 that supply refrigerant, the outdoor unit 3 can be set in the desired location, and the workload of connecting refrigerant pipes L1, L2, M1, and M2 between multiple units 4 and 5 can be reduced.

[0057] Furthermore, the specific unit in this embodiment only includes the second unit 5 of the first unit 4 and the second unit 5. In the coupled state, the first refrigerant pipes L1 and L2 and the second refrigerant pipes M1 and M2 are each arranged with their pipe ends 11-14 aligned on their pipe axes X1 and X2, and the coupling member 6 is supported by the support member 7 when the second refrigerant pipes M1 and M2 are inserted through it. Therefore, the second unit 5 can simultaneously include the coupling member 6 and the support member 7. Furthermore, by reciprocating the coupling member 6 along the pipe ends 11-14 of the first refrigerant pipes L1 and L2 and the second refrigerant pipes M1 and M2 arranged with their pipe axes X1 and X2 aligned, the first refrigerant pipes L1 and L2 and the second refrigerant pipes M1 and M2 can be efficiently coupled or disengaged. Moreover, since the coupling member 6 is supported by the second refrigerant pipes M1 and M2 and the support member 7 when the second refrigerant pipes M1 and M2 are inserted through it, detachment of the coupling member 6 can be prevented, and positioning of the coupling member 6 can be facilitated. Therefore, it can further reduce the workload of connecting refrigerant pipes L1, L2, M1, and M2 between multiple units 4 and 5.

[0058] Furthermore, the support member 7 of this embodiment has a support portion 70 that supports multiple connecting members (6A, 6B). Therefore, for example, by operating the support portion 70, the multiple connecting members 6 (6A, 6B) can be moved between the connecting position P1 and the separating position P2 at one time, thereby efficiently connecting or separating the first refrigerant pipes L1, L2 and the second refrigerant pipes M1, M2. Therefore, the workload of connecting refrigerant pipes L1, L2, M1, M2 between multiple units 4, 5 can be further reduced.

[0059] Furthermore, a specific unit in this embodiment has a holding part 37B that holds the support member 7 in the state where the connecting member 6 is in the separated position P2. Therefore, by holding the support member 7 by the holding part 37B in the state where the connecting member 6 is in the separated position P2, it is possible to prevent the connecting member 6 from interfering with the first refrigerant pipes L1, L2 and the second refrigerant pipes M1, M2. Moreover, the alignment of the pipe ends 11 to 14 of the first refrigerant pipes L1, L2 and the second refrigerant pipes M1, M2 can be easily performed. Furthermore, after aligning the pipe ends 11 to 14, by releasing the holding part 37B from the support member 7, the connecting member 6 can be moved to the connecting position P1, thereby efficiently connecting the first refrigerant pipes L1, L2 and the second refrigerant pipes M1, M2.

[0060] Furthermore, in this embodiment, the connecting component 6 includes a sleeve 60, the first refrigerant pipes L1 and L2 include first pipe ends 11 and 12, the second refrigerant pipes M1 and M2 include second pipe ends 13 and 14, and a movable body 18. When the connecting component 6 is positioned in the connecting position P1, the first pipe ends 11 and 12 are inserted into the second pipe ends 13 and 14, and the sleeve 60 contacts the movable body 18. Thus, the movable body 18 contacts the first pipe ends 11 and 12 radially with the second pipe ends 13 and 14, and the first pipe ends 11 and 12 are connected to the second pipe ends 13 and 14. Furthermore, when the connecting component 6 is positioned in the separating position P2, the movable body 18 can be spaced apart radially from the first pipe ends 11 and 12 with the second pipe ends 13 and 14, thereby separating the first pipe ends 11 and 12 from the second pipe ends 13 and 14.

[0061] According to the above structure, by bringing the sleeve 60 of the connecting member 6 into contact with the moving body 18, the first pipe ends 11 and 12 and the second pipe ends 13 and 14 are connected, thereby enabling the first refrigerant pipes L1 and L2 to be connected with the second refrigerant pipes M1 and M2. Furthermore, the moving body 18 can be radially spaced from the first pipe ends 11 and 12 of the second pipe ends 13 and 14, thereby separating the first pipe ends 11 and 12 from the second pipe ends 13 and 14, and thus releasing the connection between the first refrigerant pipes L1 and L2 and the second refrigerant pipes M1 and M2. Therefore, the first refrigerant pipes L1 and L2 and the second refrigerant pipes M1 and M2 can be connected or separated efficiently. Therefore, the workload of connecting refrigerant pipes L1, L2, M1, and M2 between multiple units 4 and 5 can be further reduced.

[0062] Furthermore, the connecting member 6 in this embodiment includes a force-applying member 61, which applies force to the sleeve 60 in a direction from the separation position P2 to the connecting position P1. The sleeve 60 resists the force applied by the force-applying member 61 and moves in a direction from the connecting position P1 to the separation position P2, thereby allowing the moving body 18 to be spaced apart from the first tube ends 11 and 12 in the radial direction of the second tube ends 13 and 14.

[0063] According to the above structure, for example, by operating the support member 7 to position the connecting member 6 in the separation position P2, the contact between the sleeve 60 and the moving body 18 can be released, thereby releasing the connection between the first pipe ends 11, 12 and the second pipe ends 13, 14. Furthermore, by operating the support member 7 to position the connecting member 6 in the connection position P1, the force-applying member 61 can apply force to the sleeve 60 in the direction from the separation position P2 to the connection position P1, thereby efficiently connecting the first pipe ends 11, 12 and the second pipe ends 13, 14. Therefore, the first refrigerant pipes L1, L2 and the second refrigerant pipes M1, M2 can be connected with reduced workload.

[0064] Furthermore, the support member 7 of this embodiment has a support portion 70, a shaft portion 72, and a through hole 71. Additionally, a specific unit has a shaft support portion 37A that provides shaft support for the shaft portion 72. By moving the support portion 70 relative to the shaft support portion 37A while the shaft portion 72 is supported by the shaft support portion 37A, the connecting member 6 reciprocates between a connecting position P1 and a separating position P2.

[0065] According to the above structure, for example, by an operator operating the support member 7, the support member 70 can be moved relative to the shaft support member 37A while the shaft 72 is supported by the shaft support member 37A. This allows the connecting member 6 to move back and forth efficiently between the connecting position P1 and the separating position P2. As a result, the first refrigerant pipes L1 and L2 and the second refrigerant pipes M1 and M2 can be connected or separated more reliably and efficiently.

[0066] Furthermore, the support portion 70 of this embodiment includes at least one protrusion 74 (74A, 74B) that protrudes from the plate surface 70a and abuts against the connecting member 6. By abutting the protrusion 74 (74A, 74B) against the connecting member 6, the connecting member 7 can support the connecting member 6. In addition, for example, by changing the protrusion height position of the protrusion 74 (74A, 74B) from the plate surface 70a, the engagement position P1 and the disengagement position P2 can be adjusted without changing the connecting member 6.

[0067] Furthermore, in this embodiment, at least one connecting member 6 includes two connecting members 6 (6A, 6B). At least one protrusion 74 (74A, 74B) includes a plurality of protrusions 74 (74A, 74B) having a protrusion height that abuts against each of the two connecting members 6 (6A, 6B) at different height positions relative to the plate surface 70a.

[0068] According to this structure, for example, even when the second refrigerant pipes M1 and M2 include two refrigerant pipes M1 and M2 with different joining positions P1 or separation positions P2, by using multiple protrusions 74 (74A, 74B) that abut against the two joining parts 6 (6A, 6B) at different height positions relative to the plate surface 70a, the two joining parts 6 (6A, 6B) corresponding to the two refrigerant pipes M1 and M2 can be moved back and forth between their respective joining positions P1 and separation positions P2 by swinging the support 70.

[0069] Furthermore, the outdoor unit 3 of this embodiment includes a cover 90 that externally covers the connecting member 6 and the support member 7. Thus, the cover 90 can prevent the connecting member 6 or the support member 7 from being accidentally operated by external forces.

[0070] Furthermore, the air conditioning unit 1 of this embodiment includes an outdoor unit 3. As a result, even when the outdoor unit 3 is large or heavy, the air conditioning unit 1 can reduce the workload during installation and can be well installed in limited spaces such as spaces with small installation area or complex layouts.

[0071] (Postscript)

[0072] The following technology has been disclosed through the above description of the embodiments.

[0073] [Technology 1] The outdoor unit of the air conditioning device of Technology 1 includes: a first unit having a first refrigerant pipe; and a second unit having a second refrigerant pipe. The first unit and the second unit are configured to be able to connect and disconnect from each other. A specific unit including at least one of the first unit and the second unit has at least one connecting member configured to connect and disconnect the first refrigerant pipe and the second refrigerant pipe. In addition, the specific unit has a support member that supports the connecting member in the connected state of the first unit and the second unit being connected, so that it can reciprocate between a connected position where the first refrigerant pipe and the second refrigerant pipe are connected by the connecting member and a disconnected position where the first refrigerant pipe and the second refrigerant pipe can be disconnected.

[0074] The outdoor unit with the above structure, by comprising a first unit and a second unit for refrigerant flow, and by keeping the first and second units separate, allows each unit to be moved to a designated location even when the number of personnel is limited or space is restricted, thus facilitating the installation of the outdoor unit in the desired location. Furthermore, for example, in the coupled state of the first and second units, the first and second refrigerant pipes can be coupled or separated by operating the support member to move the coupling member to the coupled or separated position. Therefore, the first and second units can be easily separated or coupled.

[0075] Therefore, even when the outdoor unit of an air conditioning system consists of multiple units that supply refrigerant, the outdoor unit can be placed in the desired location, reducing the workload of connecting refrigerant pipes between multiple units. As a result, even with larger or heavier outdoor units, the workload of configuring the outdoor unit can be reduced, and the outdoor unit can be well configured in confined spaces such as small installation areas or complex layouts.

[0076] [Technology 2] In the outdoor unit of the air conditioning device of Technology 2, based on the outdoor unit of the air conditioning device described in Technology 1, a specific unit includes only the second unit of the first unit and the second unit. In the combined state, the first refrigerant pipe and the second refrigerant pipe are each arranged such that the pipe ends are aligned, and the connecting member is supported by a support member with the second refrigerant pipe inserted therein.

[0077] According to the above structure, the second unit can simultaneously include a connecting component and a supporting component. Furthermore, by reciprocating the connecting component on the ends of the first and second refrigerant pipes arranged in a tube-axis alignment manner, the first and second refrigerant pipes can be efficiently connected or disconnected. Moreover, since the connecting component is supported by the second refrigerant pipe and the supporting component when the second refrigerant pipe is inserted, detachment of the connecting component can be prevented, and positioning of the connecting component is easy. Therefore, the workload of connecting refrigerant pipes between multiple units can be further reduced.

[0078] [Technology 3] In the outdoor unit of the air conditioning device of Technology 3, based on the outdoor unit of the air conditioning device described in Technology 1 or 2, the supporting member has a support portion that supports multiple connecting parts.

[0079] According to the above structure, for example, by operating one support portion of the support component, multiple connecting components can be moved between connecting and separating positions at once, thereby efficiently connecting or separating the first and second refrigerant pipes. Therefore, the workload of connecting refrigerant pipes between multiple units can be further reduced.

[0080] [Technology 4] In the outdoor unit of the air conditioning device of Technology 4, based on the outdoor unit of the air conditioning device of any one of Technologies 1 to 3, a specific unit has a retaining part that holds the supporting member in the state where the connecting member is in the separated position.

[0081] According to the above structure, by holding the support member with the retaining part in the separated position of the connecting member, interference between the connecting member and the first and second refrigerant pipes can be prevented, and the alignment of the ends of the first and second refrigerant pipes can be easily performed. Furthermore, after the ends of the pipes are aligned, by releasing the retaining part from the support member, the connecting member can be moved to the connecting position, thereby efficiently connecting the first and second refrigerant pipes.

[0082] [Technology 5] In the outdoor unit of the air conditioning device of Technology 5, based on the outdoor unit of the air conditioning device according to any one of Technologies 1 to 4, the connecting component includes a sleeve in which a first refrigerant pipe and a second refrigerant pipe can be inserted in the connecting position. The first refrigerant pipe includes a tapered first pipe end that tapers gradually. The second refrigerant pipe includes: a second pipe end whose outer peripheral surface is covered by the sleeve; and a movable body that is radially movable and held at the second pipe end. When the connecting component is in the connecting position, the first pipe end is inserted into the second pipe end and the sleeve contacts the movable body, thereby the movable body contacts the first pipe end radially, and the first pipe end and the second pipe end are connected. When the connecting component is in the disconnected position, the movable body can be radially spaced apart from the first pipe end, thereby the movable body is spaced apart from the first pipe end, and the first pipe end and the second pipe end are separated.

[0083] According to the above structure, by bringing the sleeve of the connecting component into contact with the moving body, the ends of the first and second pipes are joined, thereby enabling the first refrigerant pipe to be connected to the second refrigerant pipe. Furthermore, by using the moving body to create a radial gap between the second pipe end and the first pipe end, the ends of the first and second pipes can be separated, thus releasing the connection between the first and second refrigerant pipes. Therefore, the first and second refrigerant pipes can be efficiently connected or separated. This further reduces the workload of connecting refrigerant pipes between multiple units.

[0084] [Technology 6] In the outdoor unit of the air conditioning device of Technology 6, based on the outdoor unit of the air conditioning device described in Technology 5, the connecting component further includes a force-applying component that applies force to the sleeve in a direction from the separation position to the connecting position. The sleeve resists the force applied by the force-applying component and moves in a direction from the connecting position to the separation position, thereby enabling the moving body to be radially spaced apart from the end of the first pipe.

[0085] According to the above structure, for example, by operating the support member to position the connecting member in the separated position, the contact between the sleeve and the moving body can be released, thereby releasing the connection between the first tube end and the second tube end. Furthermore, for example, by operating the support member to position the connecting member in the connected position, force can be applied to the sleeve in the direction from the separated position to the connected position by the force-applying member, thereby efficiently connecting the first tube end and the second tube end. Therefore, the first refrigerant tube and the second refrigerant tube can be connected with reduced workload.

[0086] [Technology 7] In the outdoor unit of the air conditioning device of Technology 7, based on the outdoor unit of the air conditioning device described in any one of Technologies 1 to 6, the support member has a support portion having a flat plate surface and supporting the connecting member in a direction intersecting the plate surface. Furthermore, the support member has: a shaft portion connected to the support portion and extending in a direction parallel to the plate surface; and a through hole disposed in the support portion, through which a first refrigerant pipe or a second refrigerant pipe can be inserted. A specific unit has a shaft support portion that provides shaft support for the shaft portion. By moving the support portion relative to the shaft support portion while the shaft portion is supported by the shaft support portion, the connecting member reciprocates between a connected position and a disconnected position.

[0087] According to the above structure, for example, when an operator operates the support component, the support portion moves relative to the shaft support portion while the shaft portion is supported by the shaft support portion. This allows the connecting component to reciprocate between a connected position and a disconnected position. As a result, the first refrigerant pipe and the second refrigerant pipe can be connected or disconnected more reliably and efficiently.

[0088] [Technology 8] In the outdoor unit of the air conditioning device of Technology 8, based on the outdoor unit of the air conditioning device described in Technology 7, the support portion includes at least one protrusion that protrudes from the panel and abuts against the connecting member.

[0089] According to the above structure, by bringing the protrusion into contact with the connecting member, the connecting member can support the connecting member. Furthermore, for example, by changing the protrusion height of the protrusion from the plate surface, the connecting and separating positions can be adjusted without altering the connecting member.

[0090] [Technology 9] In the outdoor unit of the air conditioning device of Technology 9, based on the outdoor unit of the air conditioning device described in Technology 8, at least one connecting member includes two connecting members. At least one protrusion includes a plurality of protrusions having a protrusion height that abuts against each of the two connecting members at different height positions relative to the panel surface.

[0091] According to the above structure, even if the second refrigerant pipe includes two refrigerant pipes with different joint or separation positions, by using multiple protrusions that abut against the two joint members at different height positions relative to the plate surface, the two joint members corresponding to the two refrigerant pipes can be reciprocated between their respective joint and separation positions by swinging the support.

[0092] [Technology 10] The outdoor unit of the air conditioning device of Technology 10, based on the outdoor unit of the air conditioning device described in any one of Technologies 1 to 9, further includes a cover that externally covers the connecting parts and the supporting parts.

[0093] According to the above structure, the cover can prevent the connecting parts or supporting parts from being accidentally operated by external forces.

[0094] [Technology 11] The air conditioning device of Technology 11 includes the outdoor unit of the air conditioning device described in any one of Technologies 1 to 10.

[0095] According to this structure, even when the outdoor unit is larger or heavier, the workload of configuring the outdoor unit can be reduced, and the outdoor unit can be well configured in limited spaces such as small installation areas or complex layouts.

[0096] This invention is not limited to the embodiments described above. Modifications, additions, or deletions to its structure can be made without departing from the spirit of the invention. The multiple electrical components E included in the outdoor unit 3 can be appropriately distributed and arranged in each of the first unit 4 and the second unit 5. Furthermore, the number of refrigerant pipes connecting the first unit 4 and the second unit 5 can be appropriately set. Additionally, a specific unit can be only the first unit 4, or it can be both the first unit 4 and the second unit 5. The sleeve 60 can also cover the entire outer peripheral surface of the second pipe ends 13 and 14. Furthermore, the number of at least one connecting member 6 and at least one protrusion 74 can each be one, which can be set according to the number of refrigerant pipes connecting the first unit 4 and the second unit 5.
