Technical Field

[0001] This disclosure relates to heat exchange units. Background Technology

[0002] For example, Patent Document 1 describes an outdoor unit of an air conditioner with a handle mounted on the casing for use during handling, etc. The method of mounting the handle in Patent Document 1 is to provide openings and recesses on the front and rear panels of the casing for the handle to fit into, and to fix the handle by pressing it with the side panel of the casing.

[0003] Patent Document 1: Japanese Patent Application Publication No. 04-359722

[0004] The aforementioned handle installation method requires clamping the handle between various plate components within the housing, resulting in poor workability during installation. On the other hand, if an opening is provided in the housing and the handle is inserted into this opening for installation, the workability of the handle installation can be improved. However, in this case, there is a problem that the installation strength of the handle may be reduced. Summary of the Invention

[0005] This disclosure was made to solve the aforementioned problems, and aims to provide a heat exchange unit having a structure that improves the installability of the holding components while ensuring the installation strength of the holding components.

[0006] One aspect of the heat exchange unit disclosed herein is a heat exchange unit of a refrigeration cycle device. This heat exchange unit comprises: a housing having an opening; and a holding member mounted on the opening. The holding member has: a main body having an internal space opening to the outside of the housing; and a plurality of claws protruding from the main body and hooking from the inside of the housing onto the periphery of the opening. The plurality of claws includes: a plurality of first claws; and a plurality of second claws disposed in a predetermined direction intersecting the opening direction of the opening on the opposite side to the plurality of first claws. At least one of the plurality of first claws and the plurality of second claws is a cantilevered elastic claw supported on the main body. The elastic claw is capable of elastic displacement relative to the main body in the predetermined direction. The plurality of first claws includes: at least one fixed claw; and at least one of the elastic claws, wherein the protrusion height of the fixed claw relative to the main body is less than the protrusion height of the elastic claw relative to the main body.

[0007] According to this disclosure, in a heat exchange unit, the installability of the holding components can be improved while ensuring the installation strength of the holding components. Attached Figure Description

[0026] Implementation Method 1

[0027] Figure 1 This is a schematic diagram showing the general structure of the refrigeration cycle device 100 including the outdoor unit 10 in Embodiment 1. The refrigeration cycle device 100 is a device that utilizes a refrigeration cycle that circulates refrigerant 40. In Embodiment 1, the refrigeration cycle device 100 is an air conditioning device. Figure 1 As shown, the refrigeration cycle unit 100 includes an outdoor unit 10, an indoor unit 20, and a circulation path section 30. The outdoor unit 10 is located outdoors. The indoor unit 20 is located indoors. The outdoor unit 10 and the indoor unit 20 are interconnected via the circulation path section 30 for circulating refrigerant 40. The outdoor unit 10 and the indoor unit 20 are heat exchange units that exchange heat with the air.

[0028] The refrigeration cycle unit 100 can adjust the temperature of the indoor air by exchanging heat between the refrigerant 40 flowing in the circulation path section 30 and the indoor air in which the indoor unit 20 is located. Examples of refrigerants 40 include fluorinated refrigerants with low Global Warming Potential (GWP) or hydrocarbon refrigerants.

[0029] The outdoor unit 10 includes a housing 11, a compressor 12, a heat exchanger 13, a flow regulating valve 14, a blower 15, a four-way valve 16, and a control unit 17. The compressor 12, heat exchanger 13, flow regulating valve 14, blower 15, four-way valve 16, and control unit 17 are housed inside the housing 11. The control unit 17 controls the various components of the outdoor unit 10. For example, the control unit 17 is a system control unit that centrally controls the entire refrigeration cycle unit 100.

[0030] The compressor 12, heat exchanger 13, flow regulating valve 14, and four-way valve 16 are disposed in the portion of the circulation path section 30 located inside the housing 11. The compressor 12, heat exchanger 13, flow regulating valve 14, and four-way valve 16 are connected through the portion of the circulation path section 30 located inside the housing 11.

[0031] A four-way valve 16 is provided in the portion of the circulation path section 30 connected to the discharge side of the compressor 12. By switching a portion of the path in the circulation path section 30, the four-way valve 16 can reverse the direction of the refrigerant 40 flowing within the circulation path section 30. The path connected via the four-way valve 16 is... Figure 1 In the case of the path indicated by the solid line in the four-way valve 16, the refrigerant 40 flows within the circulation path section 30 at... Figure 1 The solid arrow indicates the direction of flow. On the other hand, the path connected via the four-way valve 16 is... Figure 1 In the case of the path indicated by the dashed line in the four-way valve 16, the refrigerant 40 flows within the circulation path section 30 at... Figure 1 The direction of flow is indicated by the dashed arrow.

[0032] The indoor unit 20 includes a housing 21, a heat exchanger 22, and a blower 23. The heat exchanger 22 and the blower 23 are housed inside the housing 21. The indoor unit 20 is capable of cooling the air in the room where the indoor unit 20 is located and heating the air in the room where the indoor unit 20 is located.

[0033] When the indoor unit 20 is operating in cooling mode, the refrigerant 40 flowing in the circulation path section 30 is... Figure 1The solid arrow indicates the direction of flow. That is, when the indoor unit 20 is operating in cooling mode, the refrigerant 40 flowing in the circulation path section 30 circulates sequentially through the compressor 12, the heat exchanger 13 of the outdoor unit 10, the flow regulating valve 14, and the heat exchanger 22 of the indoor unit 20, and then returns to the compressor 12. During cooling operation, the heat exchanger 13 in the outdoor unit 10 functions as a condenser, and the heat exchanger 22 in the indoor unit 20 functions as an evaporator.

[0034] On the other hand, when the indoor unit 20 is operating in heating mode, the refrigerant 40 flowing in the circulation path section 30... Figure 1 The dashed line indicates the direction of flow. That is, when the indoor unit 20 is operating in heating mode, the refrigerant 40 flowing in the circulation path section 30 circulates sequentially through the compressor 12, the heat exchanger 22 of the indoor unit 20, the flow regulating valve 14, and the heat exchanger 13 of the outdoor unit 10, and returns to the compressor 12. During heating operation, the heat exchanger 13 in the outdoor unit 10 functions as an evaporator, and the heat exchanger 22 in the indoor unit 20 functions as a condenser.

[0035] Next, the outdoor unit 10 of Embodiment 1 will be described in more detail. Figure 2 This is a 3D view of outdoor unit 10. (Example) Figure 2 As shown, the housing 11 is a generally cuboid box-shaped structure with faces facing the front-rear direction X, the width direction Y, and the vertical direction Z. In Embodiment 1, two blowers 15 arranged side-by-side along the vertical direction Z are provided inside the housing 11. The housing 11 has a detachably mounted front surface panel 11a. The front surface panel 11a is a metal plate component. The front surface panel 11a has a front wall portion 11b that forms part of the wall portion on the front side (+X side) of the housing 11 and a side wall portion 11c that forms part of the wall portion on one side (+Y side) of the housing 11 in the width direction. The side wall portion 11c bends from the end of the front wall portion 11b on one side in the width direction toward the rear side (-X side).

[0036] The outdoor unit 10 includes a gripping component 50. The gripping component 50 is a component used by operators or others to hook their fingers while handling the outdoor unit 10. In Embodiment 1, the gripping component 50 is a resin component integrally molded by injection molding or similar die molding. The resin constituting the gripping component 50 is, for example, polypropylene. Multiple gripping components 50 are provided. In Embodiment 1, a gripping component 50 is provided at each of the four corners where the wall portion in the front-rear direction X connects to the wall portion in the width direction Y of the housing 11. In Embodiment 1, the gripping component 50 is located below the center of the outdoor unit 10 in the vertical direction Z.

[0037] Figure 3This is a perspective view showing the part of the outdoor unit 10 where the holding component 50 is installed. Figure 4 This is a perspective view of the holding component 50. Figure 5 This is a view of the holding component 50 from the front (+X side). Figure 6 This is a cross-sectional view showing the holding component 50, and is Figure 5 Sectional view VI-VI in the figure. Figure 7 This is a cross-sectional view showing the holding component 50, and is Figure 5 Sectional view VII-VII in the diagram. Figure 8 This is a view of the holding component 50 from above.

[0038] Figures 3 to 8 The gripping member 50 shown is a corner gripping member 50 located in the housing 11 where the front (+X side) wall is connected to the wall on one side (+Y side) in the width direction. It is equipped with... Figures 3 to 8 The corner of the grip member 50 shown is provided on the front surface panel 11a. Although the four grip members 50 are installed in different positions and orientations, they have the same structure. Therefore, in the following description of the grip members 50, the relative positional relationships of each part of the grip members 50 that represent the four grip members 50 installed on the front surface panel 11a will be explained.

[0039] like Figure 3 As shown, the gripping member 50 is mounted on the opening 11d provided in the housing 11. The opening 11d extends through the wall portion that forms the housing 11. Figure 3 The opening 11d shown is provided in the front surface panel 11a, spanning the front wall portion 11b and the side wall portion 11c. In Embodiment 1, the opening direction of the opening 11d is a direction orthogonal to the vertical direction Z. That is, the vertical direction Z is a direction that intersects the opening direction of the opening 11d. Figure 3 The opening 11d shown opens forward (+X side) and to one side in the width direction (+Y side). The opening 11d is blocked by the mounting of the holding member 50. Figure 6 as well as Figure 7 As shown, a protrusion 11e protruding into the interior of the housing 11 is provided on the inner edge of the opening 11d. The protrusion 11e is provided at least in the portion of the inner edge of the opening 11d that faces the plurality of claw portions 60 described later.

[0040] like Figures 4 to 8 As shown, the gripping member 50 has a main body 51 and a frame 52. The main body 51 is a generally rectangular box-shaped structure with openings on the front side (+X side) and one side in the width direction (+Y side). Figure 6 as well as Figure 7 As shown, the main body 51 is housed inside the casing 11.

[0041] The main body 51 has an upper wall portion 51a, a lower wall portion 51b, an inner wall portion 51c, and a side wall portion 51d. The upper wall portion 51a is the upper wall portion among the wall portions constituting the main body 51. The lower wall portion 51b is the lower wall portion among the wall portions constituting the main body 51. The inner wall portion 51c is the rear wall portion (-X side) among the wall portions constituting the main body 51. The side wall portion 51d is the wall portion constituting the main body 51 on the opposite side (-Y side) in the width direction.

[0042] like Figure 4 As shown, the upper wall portion 51a has a through hole 54 extending through the upper wall portion 51a in the vertical direction Z. In Embodiment 1, a pair of through holes 54 are provided at intervals in the width direction Y. The through holes 54 are provided on the front side (+X side) of the upper wall portion 51a. Figure 8 As shown, the through hole 54 is approximately rectangular in length in the width direction Y when viewed in the vertical direction Z. The front edge of the through hole 54 is positioned rearward (on the -X side) than the front edge of the upper wall portion 51a.

[0043] like Figure 6 as well as Figure 7 As shown, the frame portion 52 is connected to the opening edge 51e of the main body portion 51. The frame portion 52 is frame-shaped along the opening edge 51e of the main body portion 51. The frame portion 52 protrudes outward from the opening edge 51e of the main body portion 51 throughout its entire circumference. The frame portion 52 is located outside the housing 11. The portion of the frame portion 52 that protrudes outward from the main body portion 51 contacts and hooks onto the periphery of the opening 11d in the outer side of the housing 11. The frame portion 52 clamps the periphery of the opening 11d between itself and the plurality of claw portions 60 described later.

[0044] like Figure 4 As shown, the frame portion 52 has a first portion 52a connected to the front side (+X side) of the main body portion 51 and a second portion 52b connected to one side (+Y side) of the main body portion 51 in the width direction. The first portion 52a protrudes from the main body portion 51 on both sides in the vertical direction Z and on the other side (-Y side) in the width direction. The second portion 52b extends from the end of the first portion 52a on one side in the width direction to the rear side (-X side). The second portion 52b protrudes from the main body portion 51 on both sides in the vertical direction Z and on the rear side.

[0045] The inner side of the frame portion 52 has an insertion port 52c that connects to the interior of the main body portion 51. The frame portion 52 has a cover portion 52d that covers the upper part of the opening in the main body portion 51. The main body portion 51 and the frame portion 52 constitute a finger insertion space (internal space) 53. The finger insertion space 53 is a space for the operator to insert their fingers when moving the outdoor unit 10. The finger insertion space 53 opens to the outside of the housing 11 through the insertion port 52c. The finger insertion space 53 is provided in the internal space of the main body portion 51. The operator moving the outdoor unit 10 inserts their fingers into the finger insertion space 53 and holds the cover portion 52d. Thus, the operator can hold the holding member 50 to lift the outdoor unit 10.

[0046] like Figure 6 As shown, the gripping member 50 has a plurality of claw portions 60. The plurality of claw portions 60 protrude from the main body portion 51. The plurality of claw portions 60 are located inside the housing 11. The plurality of claw portions 60 are arranged inside the housing 11 opposite to the peripheral portion of the opening 11d. In Embodiment 1, the plurality of claw portions 60 are arranged opposite to the inner end portion of the protrusion 11e provided in the opening 11d. The plurality of claw portions 60 hook onto the peripheral portion of the opening 11d from inside the housing 11.

[0047] like Figure 5 As shown, the plurality of claw portions 60 include a first claw portion 60a and a second claw portion 60b. The first claw portion 60a is a claw portion 60 disposed on the upper side of the main body portion 51. The second claw portion 60b is a claw portion 60 disposed on the lower side of the main body portion 51. That is, the second claw portion 60b is disposed on the side opposite to the first claw portion 60a in the vertical direction Z. In Embodiment 1, a plurality of first claw portions 60a and second claw portions 60b are respectively provided. The plurality of first claw portions 60a protrude upward from the upper wall portion 51a of the main body portion 51. The plurality of second claw portions 60b protrude downward from the lower wall portion 51b of the main body portion 51.

[0048] The first claw portion 60a includes a fixed claw portion 61 and a resilient claw portion 62. Both the fixed claw portion 61 and the resilient claw portion 62 protrude upwards from the upper wall portion 51a of the main body portion 51. Figure 8 As shown, in Embodiment 1, a fixing claw portion 61 is disposed between a pair of through holes 54 in the width direction Y of the upper wall portion 51a. The fixing claw portion 61 is located at the center of the upper wall portion 51a in the width direction Y. The lower end of the fixing claw portion 61 is integrally connected to the upper wall portion 51a. Figure 4 as well as Figure 6As shown, the fixing claw portion 61 is approximately triangular in shape when viewed in the width direction Y. The protrusion height of the fixing claw portion 61 relative to the main body portion 51 increases as it moves towards the front (+X side). The protrusion height of the fixing claw portion 61 relative to the main body portion 51 is the dimension of the fixing claw portion 61 in the vertical direction Z, and is the vertical direction Z distance between the upper surface of the upper wall portion 51a and the upper end portion of the fixing claw portion 61. In Embodiment 1, the upper end portion of the fixing claw portion 61 is located below the upper end portion of the frame portion 52.

[0049] like Figure 6 As shown, the fixing claw portion 61 has a first opposing surface 61f and a first inclined surface 61i opposite to the peripheral portion of the opening portion 11d. The first opposing surface 61f faces forward (+X side). The first opposing surface 61f is a surface that is approximately parallel to the vertical direction Z. Although not shown in the figure, the first opposing surface 61f is, for example, a surface that is slightly inclined relative to the vertical direction Z, with the orientation towards the upper side and located towards the rear. In Embodiment 1, the first opposing surface 61f faces the inner end portion of the protrusion 11e. The first opposing surface 61f contacts the inner end portion of the protrusion 11e. The first inclined surface 61i is a surface facing rearward and inclined upward. The upper end portion of the first inclined surface 61i is connected to the upper end portion of the first opposing surface 61f. The first inclined surface 61i is located on the upper side with the orientation towards the forward side.

[0050] The fixing claw 61 hooks onto the periphery of the opening 11d from inside the housing 11 by hooking the first opposing surface 61f onto the protrusion 11e. The upper part of the periphery of the opening 11d is clamped in the front-rear direction X by the portion of the frame 52 that protrudes upward from the main body 51 and the fixing claw 61.

[0051] like Figure 4 As shown, in Embodiment 1, a pair of elastic claw portions 62 are provided in the upper wall portion 51a such that they clamp the fixing claw portion 61 in the width direction Y. The pair of elastic claw portions 62 have the same shape. The pair of elastic claw portions 62 are respectively disposed inside a pair of through holes 54. The pair of elastic claw portions 62 are cantilevered on the inner edge of the pair of through holes 54. The rear end (-X side) of each elastic claw portion 62 is connected to the rear portion of the inner edge of each through hole 54. That is, in Embodiment 1, the elastic claw portion 62 is connected to the edge of the inner edge of the through hole 54 on the side away from the opening 11d. Thus, each elastic claw portion 62 is cantilevered on the main body portion 51. Gaps are provided between the edges of the elastic claw portion 62 and the through holes 54 on both sides in the width direction and between the elastic claw portion 62 and the front edge of the through hole 54.

[0052] like Figure 7As shown, the elastic claw portion 62 has a support portion 62a and a claw body portion 62b. In Embodiment 1, the support portion 62a is plate-shaped with its surface facing the vertical direction Z. The support portion 62a is located within the through hole 54. The support portion 62a extends from the rear side (-X side) of the inner edge of the through hole 54 to the front side (+X side). The front end of the support portion 62a is disposed opposite to the rear side of the front side portion of the inner edge of the through hole 54 with a gap.

[0053] The claw body 62b protrudes upward from the front (+X side) of the support portion 62a. The claw body 62b protrudes upward beyond the through hole 54. When viewed in the width direction Y, the claw body 62b is approximately triangular in shape. The protrusion height of the claw body 62b relative to the body portion 51 increases as it moves forward. The protrusion height of the claw body 62b relative to the body portion 51 is the vertical dimension Z of the claw body 62b, and is also the protrusion height of the elastic claw portion 62 relative to the body portion 51. The protrusion height of the elastic claw portion 62 relative to the body portion 51 is the vertical distance Z between the upper surface of the upper wall portion 51a and the upper end portion of the elastic claw portion 62.

[0054] like Figure 5 As shown, in Embodiment 1, the upper end of the elastic claw portion 62, i.e., the upper end of the claw body portion 62b, is located above the upper end of the fixed claw portion 61. That is, the protrusion height of the fixed claw portion 61 relative to the body portion 51 is less than the protrusion height of the elastic claw portion 62 relative to the body portion 51. The upper end of the elastic claw portion 62 is located below the upper end of the frame portion 52.

[0055] like Figure 7 As shown, the elastic claw portion 62 has a second opposing surface 62f and a second inclined surface 62i opposite to the peripheral portion of the opening portion 11d. The second opposing surface 62f faces forward (+X side). The second opposing surface 62f is a surface that is approximately parallel to the vertical direction Z. Although not shown in the figure, the second opposing surface 62f is, for example, a surface that is slightly inclined relative to the vertical direction Z, with the direction towards the upper side and located on the rear side. The second opposing surface 62f is connected to the upper side of the front surface of the support portion 62a. In Embodiment 1, the second opposing surface 62f faces the inner end of the protrusion 11e. The second opposing surface 62f contacts the inner end of the protrusion 11e. The second inclined surface 62i is a surface that faces rearward (-X side) and is obliquely upward. The upper end of the second inclined surface 62i is connected to the upper end of the second opposing surface 62f. The second inclined surface 62i is located on the upper side with the direction towards the forward side.

[0056] The elastic claw 62 hooks onto the periphery of the opening 11d from inside the housing 11 by hooking the second opposing surface 62f onto the protrusion 11e. The upper part of the periphery of the opening 11d is clamped in the front-rear direction X by the portion of the frame 52 that protrudes upward from the main body 51 and the elastic claw 62.

[0057] like Figure 8 As shown, in Embodiment 1, the width Y dimension of the elastic claw portion 62 is greater than the width Y dimension of the fixed claw portion 61. The front (+X side) surface of the elastic claw portion 62 is located slightly forward of the front surface of the fixed claw portion 61. That is, the second opposing surface 62f is located on the side closer to the periphery of the opening 11d than the first opposing surface 61f.

[0058] The elastic claw portion 62 can be elastically displaced in the vertical direction Z relative to the main body portion 51. More specifically, the connecting portion of the support portion 62a that connects to the inner edge of the through hole 54 elastically deforms in the vertical direction Z, so that the elastic claw portion 62 can use the connecting portion of the support portion 62a and the inner edge of the through hole 54 as a fulcrum to elastically displace in the vertical direction Z.

[0059] like Figure 5 As shown, the second claw portion 60b includes a fixed claw portion 63. The fixed claw portion 63 protrudes downward from the lower wall portion 51b of the main body portion 51. In Embodiment 1, a pair of fixed claw portions 63 are provided at intervals in the width direction Y. The pair of fixed claw portions 63 are respectively positioned to overlap with a pair of elastic claw portions 62 when viewed in the vertical direction Z. The upper end portion of the fixed claw portion 63 is integrally connected to the lower wall portion 51b. Figure 7 As shown, the fixing claw portion 63 is approximately isosceles triangular in shape when viewed in the width direction Y. The protrusion height of the fixing claw portion 63 relative to the main body portion 51, i.e., the protrusion height of the second claw portion 60b relative to the main body portion 51, is greater than the protrusion height of the elastic claw portion 62 relative to the main body portion 51. In Embodiment 1, the protrusion height of the fixing claw portion 63 relative to the main body portion 51 is greater than the protrusion height of the elastic claw portion 62 relative to the main body portion 51. The protrusion height of the fixing claw portion 63 relative to the main body portion 51 is the dimension of the fixing claw portion 63 in the vertical direction Z, and is the distance in the vertical direction Z between the lower surface of the lower wall portion 51b and the lower end of the fixing claw portion 63. In Embodiment 1, the lower end of the fixing claw portion 63 is located below the lower end of the frame portion 52.

[0060] The fixing claw portion 63 has a third opposing surface 63f opposite to the peripheral portion of the opening portion 11d. The third opposing surface 63f faces forward (+X side). The third opposing surface 63f is a surface that is inclined relative to the vertical direction Z, facing downward and located on the rear side (-X side). In Embodiment 1, the third opposing surface 63f faces the inner end of the protrusion 11e. The third opposing surface 63f contacts the inner end of the protrusion 11e. The rear surface of the fixing claw portion 63 and the third opposing surface 63f are symmetrically arranged in the front-rear direction X.

[0061] The retaining claw 63 hooks onto the periphery of the opening 11d from inside the housing 11 by hooking the third opposing surface 63f onto the protrusion 11e. The lower portion of the periphery of the opening 11d is clamped in the front-rear direction X by the portion of the frame 52 that protrudes downward from the main body 51 and the retaining claw 63.

[0062] Figure 9 This is a cross-sectional view showing a portion of the step of mounting the holding component 50 onto the housing 11. Figure 10 This is a cross-sectional view showing another part of the step of installing the gripping member 50 onto the housing 11. To install the gripping member 50 onto the housing 11, the operator approaches the opening 11d from the outside of the housing 11 and tilts the gripping member 50 relative to the vertical direction Z, thereby inserting the lower part of the main body 51 and the fixing claw 63 provided on the lower part of the main body 51 into the opening 11d.

[0063] With the fixed claw 63 hooked inside the housing 11 and around the periphery of the opening 11d, the operator restores the slope of the gripping member 50 relative to the vertical direction Z while... Figure 9 The upper part of the main body 51 is inserted into the opening 11d, as shown. Furthermore, in... Figure 9 as well as Figure 10 The diagram shows the upper part of the main body 51 being moved straight to the rear (-X side) and inserted into the opening 11d. However, in practice, for example, the lower part of the gripping member 50 hooked to the opening 11d is used as a fulcrum to rotate the gripping member 50, thereby inserting the upper part of the main body 51 into the opening 11d.

[0064] If the upper part of the main body 51 is inserted into the opening 11d, the second inclined surface 62i of the elastic claw 62 contacts the upper edge of the opening 11d. In this state, when the gripping member 50 is further pushed into the opening 11d, as... Figure 10As shown, the second inclined surface 62i is pressed by the edge of the opening 11d, and the elastic claw 62 uses the connection between the support 62a and the inner edge of the through hole 54 as a fulcrum to elastically displace in the direction (-Z direction) towards the interior of the main body 51. As a result, the protrusion height of the elastic claw 62 relative to the main body 51 can be reduced, and the elastic claw 62 can be easily inserted into the opening 11d.

[0065] If the main body 51 is further pushed into the opening 11d and the entire elastic claw 62 passes through the opening 11d, the elastically deformed support 62a undergoes a restorative deformation, and the elastic claw 62 returns to its original state. Thus, the second opposing surface 62f of the elastic claw 62 is positioned opposite the inner end of the protrusion 11e, and the elastic claw 62 hooks from the inside of the housing 11 onto the periphery of the opening 11d.

[0066] Furthermore, when the gripping member 50 is pushed into the opening 11d as described above, the fixing claw 61, located on the upper side of the main body 51, also contacts the upper edge of the opening 11d in the same way as the elastic claw 62. Here, the protrusion height of the fixing claw 61 is smaller than that of the elastic claw 62. Therefore, when the gripping member 50 is pushed into the opening 11d, at least one of the inner edge of the opening 11d and the fixing claw 61 undergoes slight elastic deformation, thereby allowing the fixing claw 61 to be inserted into the housing 11 through the opening 11d. When the fixing claw 61 passes through the opening 11d, the elastically deformed portion undergoes restorative deformation, resulting in the first opposing surface 61f of the fixing claw 61 facing the inner end of the protrusion 11e. Thus, the fixing claw 61 hooks from the inside of the housing 11 onto the periphery of the opening 11d.

[0067] As described above, in Embodiment 1, the gripping member 50 is installed in the opening 11d of the housing 11 by pushing the gripping member 50 from the outside of the housing 11 into the opening 11d. With the gripping member 50 installed in the housing 11, the periphery of the opening 11d is clamped by the plurality of claw portions 60 and the frame portion 52. This prevents the gripping member 50 from falling out of the opening 11d.

[0068] When a conventional gripping member is installed by inserting it from the outside of the housing 11 into the opening 11d, as described above with the gripping member 50, after inserting the claw on the vertical Z side into the opening 11d first, all the claws on the other side of the vertical Z are pushed into the opening 11d in the same manner as the fixed claw 61 described above. That is, at least one of the inner edge of the opening 11d and all the claws on the other side of the vertical Z is slightly elastically deformed, and the claw is pushed into the opening 11d. In this case, if the protrusion height of the claw pushed in by elastic deformation is large, the claw will hook onto the inner edge of the opening 11d and cannot be pushed into the opening 11d, so it is necessary to reduce the protrusion height of the claw. Therefore, when a conventional gripping member is installed by pushing it from the outside of the housing 11 into the opening 11d, it is difficult to make the claws protrude sufficiently, and it is difficult to securely install the gripping member into the housing 11.

[0069] In contrast, according to Embodiment 1, an elastic claw portion 62 is provided that is cantilevered and supported on the main body portion 51. The elastic claw portion 62 can elastically displace relative to the main body portion 51 in the vertical direction Z. Therefore, the gripping member 50 can be inserted into the opening portion 11d while the elastic claw portion 62 is elastically displaced as described above to reduce its protrusion height relative to the main body portion 51. Furthermore, after the elastic claw portion 62 passes through the opening portion 11d, the elastic claw portion 62 returns to its original displacement, and its protrusion height relative to the main body portion 51 returns to its original height. Thus, even if the protrusion height of the elastic claw portion 62 is increased to a certain extent, the elastic claw portion 62 can be easily inserted into the housing 11 simply by pushing the gripping member 50 into the opening portion 11d. Therefore, by increasing the protrusion height of the claw portions 60 provided on both sides of the main body portion 51 in the vertical direction Z, the gripping member 50 can be securely installed relative to the opening portion 11d.

[0070] As described above, according to Embodiment 1, the ease of installation of the gripping member 50 can be improved while ensuring the installation strength of the gripping member 50. Furthermore, when installing the gripping member 50, the operator can easily confirm that the gripping member 50 is installed in the opening 11d based on the sound or feel generated when the elastic claw 62 returns to its original position. Therefore, the ease of installation of the gripping member 50 can be further improved.

[0071] Furthermore, since the gripping member 50 is installed in the housing 11 by pushing it into the opening 11d from the outside of the housing 11, the gripping member 50 can be installed at any location on the housing 11 as long as the opening 11d is provided. Therefore, compared to the case where the gripping member 50 is held by being clamped between two or more components constituting the housing 11, the design freedom of the mounting location of the gripping member 50 in the housing 11 can be increased. Thus, the gripping member 50 can be installed in a location within the housing 11 that is easily accessible to the operator.

[0072] Furthermore, according to Embodiment 1, the elastic claw portion 62 is the first claw portion 60a. The protrusion height of the second claw portion 60b relative to the main body portion 51 is greater than or equal to the protrusion height of the elastic claw portion 62 relative to the main body portion 51. Therefore, the protrusion height of the second claw portion 60b can be increased by having an elastic claw portion 62 with a relatively large protrusion height, as described above. As a result, the protrusion height of the elastic claw portion 62, which is the first claw portion 60a, and the protrusion height of the second claw portion 60b can be appropriately increased respectively. Therefore, the gripping member 50 can be more securely mounted to the opening portion 11d.

[0073] Furthermore, according to Embodiment 1, the main body 51 has a through hole 54 that penetrates the wall portion constituting the main body 51. The elastic claw portion 62 is cantilevered and supported on the inner edge of the through hole 54. Therefore, the elastic claw portion 62 can be easily cantilevered and supported relative to the main body 51. Additionally, the elastic claw portion 62 can be easily elastically displaced via the through hole 54.

[0074] Furthermore, according to Embodiment 1, the elastic claw portion 62 is connected to the edge portion of the inner edge of the through hole 54 on the side away from the opening 11d. Therefore, compared to the case where the elastic claw portion 62 is connected to the edge portion of the inner edge of the through hole 54 on the side near the opening 11d, when the gripping member 50 is pushed into the opening 11d, the elastic claw portion 62 is more easily elastically displaced toward the inner edge portion away from the opening 11d. As a result, the elastic claw portion 62 can be appropriately elastically displaced, making it easier to install the gripping member 50 into the opening 11d.

[0075] Furthermore, according to Embodiment 1, the elastic claw portion 62 is provided on the upper side of the main body portion 51 in the vertical direction. Therefore, the through hole 54 is also provided on the upper wall portion 51a of the main body portion 51. As a result, compared with the case where the through hole 54 is provided on the lower wall portion 51b of the main body portion 51, it is possible to prevent foreign objects such as rainwater from entering the interior of the housing 11 through the through hole 54.

[0076] Furthermore, according to Embodiment 1, multiple first claw portions 60a are provided. Each multiple first claw portion 60a includes a fixed claw portion 61 and a resilient claw portion 62. Therefore, in addition to the resilient claw portion 62, the fixed claw portion 61 can also hook onto the periphery of the opening 11d. This allows the gripping member 50 to be more securely mounted to the opening 11d. Furthermore, the protrusion height of the fixed claw portion 61 relative to the main body 51 is less than the protrusion height of the resilient claw portion 62 relative to the main body 51. Therefore, even without being configured as a cantilever support like the resilient claw portion 62, the fixed claw portion 61 can be pushed into the opening 11d. By providing the fixed claw portion 61, which is not cantilever supported, forces applied to the gripping member 50 during the handling of the outdoor unit 10 can be received not only by the resilient claw portion 62 but also by the fixed claw portion 61. Therefore, excessive load on the resilient claw portion 62 can be suppressed. Therefore, stress concentration in the part of the elastic claw 62 connected to the through hole 54, i.e., the root part of the support 62a, can be suppressed, and damage to the elastic claw 62 can be suppressed.

[0077] Furthermore, according to Embodiment 1, the second opposing surface 62f of the elastic claw portion 62 is located on the side closer to the periphery of the opening 11d than the first opposing surface 61f of the fixed claw portion 61. Therefore, when the holding member 50 is pulled to the outside of the housing 11 during the handling of the outdoor unit 10, the second opposing surface 62f of the elastic claw portion 62 can contact the periphery of the opening 11d before the first opposing surface 61f of the fixed claw portion 61. This prevents the fixed claw portion 61 from being pulled out of the opening 11d. Therefore, the holding member 50 can be installed more stably in the opening 11d. In addition, when the holding member 50 is installed in the opening 11d, the fixed claw portion 61 passes through the opening 11d before the elastic claw portion 62 passes through it. Therefore, at the moment when it can be confirmed by sound or feeling that the elastic claw portion 62 has made its recovery displacement and passed through the opening 11d, the fixed claw portion 61 has already passed through the opening 11d. Therefore, by confirming that the elastic claw 62 has passed through the opening 11d based on sound or feeling, it is easy to confirm that the gripping member 50 is properly installed in the housing 11.

[0078] Furthermore, according to Embodiment 1, the plurality of first claw portions 60a include a plurality of elastic claw portions 62. Therefore, the gripping member 50 can be more securely mounted to the opening 11d by the plurality of elastic claw portions 62. Moreover, compared to increasing the width Y dimension of one elastic claw portion 62 to improve the mounting strength of the gripping member 50, the width Y dimension of each elastic claw portion 62 can be reduced, allowing each elastic claw portion 62 to easily elastically displace. Therefore, the gripping member 50 can be more easily mounted to the opening 11d.

[0079] Furthermore, according to Embodiment 1, the gripping member 50 has a frame-shaped frame portion 52 along the opening edge 51e of the main body portion 51. The frame portion 52 is located outside the housing 11 and clamps the peripheral portion of the opening 11d between itself and the plurality of claw portions 60. Therefore, the peripheral portion of the opening 11d can be stably clamped by the frame portion 52 and the plurality of claw portions 60, and the gripping member 50 can be more securely mounted to the opening 11d.

[0080] Furthermore, according to Embodiment 1, the heat exchange unit equipped with a holding member 50 having an elastic claw portion 62 is the outdoor unit 10. The outdoor unit 10 is heavier than the indoor unit 20. Therefore, the outdoor unit 10 is more difficult to move than the indoor unit 20. In this regard, by providing a holding member 50 as described above to ensure installation strength, the outdoor unit 10 can be easily moved via the holding member 50.

[0081] Furthermore, according to Embodiment 1, the upper end of the first claw portion 60a is located below the upper end of the frame portion 52. The lower end of the second claw portion 60b is located below the lower end of the frame portion 52. Therefore, when viewing the gripping member 50 from the front (+X side), the first claw portion 60a is obscured by the frame portion 52 and cannot be visually confirmed. On the other hand, the lower end of the second claw portion 60b protrudes downward beyond the frame portion 52. Therefore, before installing the gripping member 50 onto the housing 11, the lower end of the second claw portion 60b can be visually confirmed from the front. Thus, the operator installing the gripping member 50 can easily determine the orientation of the gripping member 50 when installed on the housing 11 by visually confirming the second claw portion 60b protruding beyond the frame portion 52.

[0082] Furthermore, according to Embodiment 1, the surface of the elastic claw portion 62 located on the side opposite to the side where the opening portion 11d is located becomes a second inclined surface 62i inclined relative to the vertical direction Z. Therefore, when the gripping member 50 is inserted into the opening portion 11d, the edge of the opening portion 11d contacts the second inclined surface 62i. As a result, when the gripping member 50 is inserted into the opening portion 11d, the elastic claw portion 62 is unlikely to hook onto the edge of the opening portion 11d, and the elastic claw portion 62 is easily elastically displaced. In addition, it is difficult to apply excessive force to the edge of the opening portion 11d. Therefore, deformation of the opening portion 11d can be suppressed.

[0083] Implementation Method 2

[0084] Figure 11 This is a perspective view showing the holding member 250 in embodiment 2. Figure 12 This is a top view of the gripping member 250 in Embodiment 2. Furthermore, in the following description, the same reference numerals will be appropriately used to label structures similar to those in the above-described embodiment, and descriptions may sometimes be omitted.

[0085] like Figure 11 as well as Figure 12 As shown, in the gripping member 250 of Embodiment 2, unlike the upper wall portion 51a of Embodiment 1, the upper wall portion 251a of the main body portion 251 has only one through hole 54 at the center portion in the width direction Y. The other structures of the main body portion 251 are the same as the other structures of the main body portion 51 in Embodiment 1.

[0086] The gripping member 250 includes a plurality of first claw portions 260a, each comprising two fixed claw portions 261 and one resilient claw portion 262. One resilient claw portion 262 is disposed in a through hole 54. The two fixed claw portions 261 are configured to clamp one resilient claw portion 262 in the width direction Y. The other structures of the fixed claw portions 261 are the same as those of the fixed claw portion 61 in Embodiment 1. The other structures of the resilient claw portion 262 are the same as those of the resilient claw portion 62 in Embodiment 1. The other structures of the gripping member 250 are the same as those of the gripping member 50 in Embodiment 1.

[0087] According to Embodiment 2, the plurality of first claw portions 260a include a plurality of fixed claw portions 261 and only one elastic claw portion 262. Therefore, the stress applied to the elastic claw portion 262 can be appropriately received by the plurality of fixed claw portions 261. As a result, breakage of the elastic claw portion 262 can be suppressed, and the gripping member 250 can be properly and stably installed in the opening 11d. In addition, when installing the gripping member 250, if it can be confirmed by sound or touch that one elastic claw portion 262 has undergone restorative displacement within the housing 11 and hooked onto the periphery of the opening 11d, it can be confirmed that the gripping member 250 is properly installed in the opening 11d. That is, if one elastic claw portion 262 can be properly inserted into the housing 11, it is not necessary to confirm whether the other elastic claw portions 262 are properly inserted into the housing 11. As a result, it is possible to suppress the gripping member 250 from being installed in the housing 11 with the elastic claw portion 262 having undergone elastic displacement within the opening 11d. Therefore, the holding member 250 can be installed more appropriately and easily relative to the opening 11d.

[0088] Implementation Method 3

[0089] Figure 13 This is a top view of the gripping member 350 in Embodiment 3. Furthermore, in the following description, the same reference numerals are appropriately used to denote structures similar to those in the embodiments described above, and descriptions are sometimes omitted.

[0090] like Figure 13 As shown, in the gripping member 350 of Embodiment 3, the main body 351 has the same structure as the main body 51 of Embodiment 1, except that the arrangement of the two through holes 54 in the upper wall 351a is different.

[0091] The plurality of first claw portions 360a include one fixed claw portion 361 and two resilient claw portions 362. The fixed claw portion 361 is arranged side-by-side on the opposite side (-Y side) of the width direction of the two resilient claw portions 362. The two resilient claw portions 362 are arranged side-by-side in the width direction Y. The dimension of the resilient claw portion 362 in the width direction Y is smaller than the dimension of the fixed claw portion 361 in the width direction Y. Therefore, when the gripping member 350 is installed, the resilient claw portions 362 can be easily elastically displaced. This makes it easier to install the gripping member 350.

[0092] The other structures of the fixing claw portion 361 are the same as those of the fixing claw portion 61 in Embodiment 1. The other structures of the elastic claw portion 362 are the same as those of the elastic claw portion 62 in Embodiment 1. The other structures of the gripping member 350 are the same as those of the gripping member 50 in Embodiment 1.

[0093] Implementation Method 4

[0094] Figure 14 This is a top view of the gripping member 450 in Embodiment 4. Furthermore, in the following description, the same reference numerals are appropriately used to denote structures similar to those in the embodiments described above, and descriptions are sometimes omitted.

[0095] like Figure 14 As shown, in the gripping member 450 of Embodiment 4, the plurality of first claw portions 460a include only two elastic claw portions 62. Unlike Embodiment 1, the plurality of first claw portions 460a do not include a fixed claw portion 61. Therefore, the gripping member 450 can be manufactured more easily than when a fixed claw portion 61 is provided. The other structures of the gripping member 450 are the same as those of the gripping member 50 of Embodiment 1.

[0096] Implementation Method 5

[0097] Figure 15 This is a top view of the gripping member 550 in Embodiment 5. Furthermore, in the following description, the same reference numerals will be appropriately used to label structures similar to those in the embodiments described above, and descriptions may sometimes be omitted.

[0098] like Figure 15As shown, in the gripping member 550 of Embodiment 5, the main body 551 has the same structure as the main body 251 of Embodiment 2, except that a through hole 54 in the upper wall 551a is located near the side in the width direction (+Y side). The plurality of first claw portions 560a include only one fixed claw portion 561 and one resilient claw portion 562. Therefore, while reducing the number of first claw portions 560a to facilitate the manufacture of the gripping member 550, the mounting strength of the gripping member 550 can be improved by using the fixed claw portion 561 and the resilient claw portion 562. One fixed claw portion 561 is located on the other side (-Y side) in the width direction of one resilient claw portion 562.

[0099] The other structures of the fixing claw portion 561 are the same as those of the fixing claw portion 61 in Embodiment 1. The other structures of the elastic claw portion 562 are the same as those of the elastic claw portion 62 in Embodiment 1. The other structures of the gripping member 550 are the same as those of the gripping member 50 in Embodiment 1.

[0100] The embodiments of this disclosure have been described above, but this disclosure is not limited to the structures of the above embodiments, and the following structures and methods may also be used.

[0101] If the plurality of claws includes at least one first claw and at least one second claw, then any other claws may also be included. If at least one of the at least one first claw and at least one second claw is a resilient claw, then the other first claws and second claws may also be any claws. Resilient claws may also be included in both the first claw and the second claw. All of the first claws and second claws may also be resilient claws. The shape of each claw may also be any shape.

[0102] There is no particular limitation on the protrusion height of each claw relative to the main body. The protrusion height of the first claw relative to the main body may also be greater than that of the second claw relative to the main body. The protrusion height of the elastic claw relative to the main body may also be greater than that of the second claw relative to the main body. There is no particular limitation on the relationship between the protrusion heights of each claw and the frame. As long as the elastic claw is cantilevered relative to the main body, it may be connected to the main body in any manner. Regarding the prescribed direction for setting the first and second claws, as long as it is a direction intersecting the opening direction of the opening, it may not be a vertical direction.

[0103] The heat exchange unit equipped with the holding component of this disclosure can also be an indoor unit of a refrigeration cycle device. In this case, the indoor unit may be, for example, a floor-standing indoor unit or a wall-mounted indoor unit. The refrigeration cycle device equipped with the heat exchange unit of this disclosure is not limited to an air conditioning device, as long as it is a device that utilizes a refrigeration cycle for refrigerant circulation. The refrigeration cycle device may also be a heat pump water heater, etc.

[0104] The structures and methods described above can be appropriately combined within the scope of mutual non-contradiction.
