[0013] Embodiment 1. FIG. 1 is a schematic diagram showing a schematic configuration of a refrigeration cycle device 100 according to Embodiment 1. The refrigeration cycle device 100 is a device that utilizes a refrigeration cycle in which a refrigerant 19 circulates. In Embodiment 1, the refrigeration cycle device 100 is an air conditioner. As shown in FIG. 1, the refrigeration cycle device 100 includes an outdoor unit 10, an indoor unit 20, and a circulation path section 18. The outdoor unit 10 is disposed outdoors. The indoor unit 20 is disposed indoors. The outdoor unit 10 and the indoor unit 20 are connected to each other by a circulation path section 18 through which the refrigerant 19 circulates. The outdoor unit 10 and the indoor unit 20 are heat exchange units that perform heat exchange with air.

[0014] The refrigeration cycle device 100 can adjust the temperature of the indoor air by performing heat exchange between the refrigerant 19 flowing in the circulation path section 18 and the air in the room where the indoor unit 20 is disposed. Examples of the refrigerant 19 include a fluorine-based refrigerant with a low global warming potential (GWP: Global Warming Potential) or a hydrocarbon-based refrigerant. The density of the refrigerant 19 in the gaseous state is greater than the density of air. Here, the fluorine-based refrigerant with a low global warming potential is, for example, HFC32, and the hydrocarbon-based refrigerant is, for example, R290 (propane). Both the fluorine-based refrigerant and the hydrocarbon-based refrigerant are flammable refrigerants.

[0015] The outdoor unit 10 includes a housing 11, a compressor 12, a heat exchanger 13, a flow rate adjustment valve 14, a blower 15, a four-way valve 16, a refrigerant pipe 18a, and a control unit 30. Inside the housing 11, the compressor 12, the heat exchanger 13, the flow rate adjustment valve 14, the blower 15, the four-way valve 16, the refrigerant pipe 18a, and the control unit 30 are accommodated.

[0016] The compressor 12, the heat exchanger 13, the flow rate adjustment valve 14, and the four-way valve 16 are provided in a portion of the circulation path portion 18 that is located inside the housing 11. The compressor 12, the heat exchanger 13, the flow rate adjustment valve 14, and the four-way valve 16 are connected by a portion of the circulation path portion 18 that is located inside the housing 11.

[0017] The four-way valve 16 is provided in a portion of the circulation path portion 18 that is connected to the discharge side of the compressor 12. The four-way valve 16 can reverse the direction of the refrigerant 19 flowing in the circulation path portion 18 by switching a part of the path of the circulation path portion 18. When the path connected by the four-way valve 16 is the path indicated by the solid line in the four-way valve 16 of FIG. 1, the refrigerant 19 flows in the circulation path portion 18 in the direction indicated by the solid line arrow in FIG. 1. On the other hand, when the path connected by the four-way valve 16 is the path indicated by the broken line in the four-way valve 16 of FIG. 1, the refrigerant 19 flows in the circulation path portion 18 in the direction indicated by the broken line arrow in FIG. 1.

[0018] The refrigerant pipe 18a is a pipe that constitutes a part of the circulation path portion 18. The refrigerant pipe 18a is connected to a pipe extending from the indoor unit 20. A plurality of refrigerant pipes 18a are provided in the housing 11 of the outdoor unit 10.

[0019] The indoor unit 20 includes a housing 21, a heat exchanger 22, a blower 23, and a control unit 24. The housing 21 houses the heat exchanger 22, the blower 23, and the control unit 24 inside. The indoor unit 20 can perform a cooling operation for cooling the air in the room where the indoor unit 20 is arranged and a heating operation for heating the air in the room where the indoor unit 20 is arranged.

[0020] When the indoor unit 20 is in the cooling operation, the refrigerant 19 flowing in the circulation path portion 18 flows in the direction indicated by the solid line arrow in FIG. 1. That is, when the indoor unit 20 is in the cooling operation, the refrigerant 19 flowing in the circulation path portion 18 circulates through the compressor 12, the heat exchanger 13 of the outdoor unit 10, the flow rate adjustment valve 14, and the heat exchanger 22 of the indoor unit 20 in this order and returns to the compressor 12. In the 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.

[0021] On the other hand, when the indoor unit 20 is in heating operation, the refrigerant 19 flowing in the circulation path portion 18 flows in the direction indicated by the dashed line in FIG. 1. That is, when the indoor unit 20 is in heating operation, the refrigerant 19 flowing in the circulation path portion 18 circulates through the compressor 12, the heat exchanger 22 of the indoor unit 20, the flow rate adjustment valve 14, and the heat exchanger 13 of the outdoor unit 10 in this order and returns to the compressor 12. In the 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.

[0022] Next, the outdoor unit 10 will be described in more detail. FIG. 2 is a perspective view showing a part of the outdoor unit 10. As shown in FIG. 2, the housing 11 has a blower chamber 11a and a machine chamber 11b partitioned from each other by a partition member 11c. The partition member 11c extends in the vertical direction Z. The partition member 11c is in the shape of a substantially rectangular plate with its plate surface facing the left-right direction Y. The upper end portion of the partition member 11c is disposed at a distance downward from a top surface panel (not shown) of the housing 11. The top surface panel (not shown) is the upper wall portion among the wall portions constituting the housing 11.

[0023] The blower chamber 11a and the machine chamber 11b are arranged adjacent to each other in the left - right direction Y. The dimension of the blower chamber 11a in the left - right direction Y is larger than the dimension of the machine chamber 11b in the left - right direction Y. The blower chamber 11a is located on the left side of the machine chamber 11b. Inside the blower chamber 11a, a heat exchanger 13 and a blower 15 are arranged. In Embodiment 1, the heat exchanger 13 is substantially L - shaped when viewed in the vertical direction Z. The heat exchanger 13 has a first portion 13a that extends in the left - right direction Y when viewed in the vertical direction Z, and a second portion 13b that extends forward (+X side) from the left - hand end of the first portion 13a when viewed in the vertical direction Z.

The second portion 13b is arranged at the left - hand end within the blower chamber 11a. Within the blower chamber 11a, the blower 15 is located in front of the first portion 13a of the heat exchanger 13 and to the right of the second portion 13b of the heat exchanger 13.

[0024] When the blower 15 is driven, air is sucked into the blower chamber 11a from a suction port (not shown) provided in the rear - side (-X side) wall portion of the blower chamber 11a. The air sucked into the blower chamber 11a passes through the heat exchanger 13 and is blown out of the housing 11 from a blow - out port (not shown) provided in the front - side (+X side) wall portion of the blower chamber 11a. In this way, the blower 15 sends air to the heat exchanger 13.

[0025] Inside the machine chamber 11b, a compressor 12 is arranged. The compressor 12 is arranged in the lower portion inside the machine chamber 11b. The compressor 12 is substantially cylindrical and extends in the vertical direction Z. As shown in FIG. 1, a plurality of refrigerant pipes 18a are arranged inside the machine chamber 11b.

[0026] The control unit 30 controls each part of the outdoor unit 10. The control unit 30 is, for example, a system control unit that overall controls the entire refrigeration cycle device 100. As shown in FIG. 2, the control unit 30 is disposed across the inside of the blower chamber 11a and the inside of the machine chamber 11b. The control unit 30 extends in the left-right direction Y. The control unit 30 includes an electric component box 40, a first electric component 70, a connecting portion 31, a wall member 50, a holding member 60, and second electric components 73 and 74.

[0027] The electric component box 40 has a box shape that is long in the left-right direction Y. The electric component box 40 is housed inside the housing 11. In Embodiment 1, the electric component box 40 is disposed inside the blower chamber 11a. The electric component box 40 is located above and separated from the blower 15 inside the blower chamber 11a. The electric component box 40 is located at the upper end portion inside the blower chamber 11a. The electric component box 40 is fixed to the housing 11. The right end portion of the electric component box 40 is located to the left and separated from the partition member 11c. In Embodiment 1, the electric component box 40 is made of metal. The electric component box 40 is made, for example, by performing press working on sheet metal.

[0028] FIG. 3 is an exploded perspective view showing the electric component box 40. As shown in FIG. 3, the electric component box 40 includes an electric component box body 41 and a lid body 42. The electric component box body 41 is a box-shaped member having an opening 41h that opens upward. The opening 41h has a rectangular shape having a pair of sides extending in the front-rear direction X and a pair of sides extending in the left-right direction Y. The opening 41h extends in the left-right direction Y.

[0029] The bottom wall portion 41a of the electric component box body 41 has an inclined wall portion 41b that is inclined in the front-rear direction X with respect to a plane (XY plane) orthogonal to the vertical direction Z. The inclined wall portion 41b is located on the upper side as it goes toward the rear side (-X side). The inclined wall portion 41b constitutes the rear side portion of the bottom wall portion 41a. The rear end portion of the inclined wall portion 41b is the rear end portion of the bottom wall portion 41a. The bottom wall portion 41a is the wall portion located on the lower side among the wall portions constituting the electric component box body 41.

[0030] FIG. 4 is an exploded perspective view showing the main body 41 of the electrical component box and each component fixed to the main body 41 of the electrical component box. As shown in FIG. 4, a rectangular through-hole 41f is formed in the inclined wall portion 41b. The through-hole 41f is formed in the right side (+Y side) portion of the inclined wall portion 41b.

[0031] As shown in FIG. 3, a first electrical component 70 is fixed to the inner surface of the inclined wall portion 41b facing the inside of the main body 41 of the electrical component box. The first electrical component 70 is housed inside the electrical component box 40. The first electrical component 70 includes a substrate 71 and a plurality of electrical components 72 attached to the substrate 71. The substrate 71 is a rectangular plate-shaped with the plate surface facing upward and the front side (+X side). The substrate 71 is a control board on which a control circuit for controlling the outdoor unit 10 is mounted. The plurality of electrical components 72 are attached to the upper surface of the substrate 71. The plurality of electrical components 72 include a microcomputer for controlling each part of the outdoor unit 10 and a switch component for switching a connection state of a part of the control circuit mounted on the substrate 71.

[0032] In Embodiment 1, the substrate 71 is fixed to the inclined wall portion 41b via a substrate holding member 47. As shown in FIG. 4, the substrate holding member 47 includes a resin case 47a that supports the substrate 71 from below, and a frame-shaped resin holder 47b that sandwiches the outer edge portion of the substrate 71 between the resin case 47a. The resin holder 47b is fixed to the resin case 47a by a plurality of bolts 92. The resin case 47a is fixed to the inclined wall portion 41b by a plurality of bolts 93. The plurality of bolts 93 are passed through bolt holes formed in the peripheral portion of the through-hole 41f in the inclined wall portion 41b from the outside of the electrical component box 40 and tightened to the resin case 47a.

[0033] A rectangular frame-shaped sealing member 82 is provided between the resin case 47a and the inclined wall portion 41b. The frame-shaped sealing member 82 seals the space between the resin case 47a and the inclined wall portion 41b. The frame-shaped sealing member 82 is composed of a pair of first sealing members 82a extending in the direction in which the inclined wall portion 41b inclines and a pair of second sealing members 82b extending in the left-right direction Y, which are combined in a rectangular frame shape. Holes through which bolts 93 for fixing the resin case 47a to the inclined wall portion 41b pass are formed in the pair of first sealing members 82a and the pair of second sealing members 82b. The frame-shaped sealing member 82 is elastically deformable. The material constituting the frame-shaped sealing member 82 is, for example, urethane and an EPDM (Ethylene Propylene Diene Methylene) material (ethylene propylene diene rubber).

[0034] A heat sink 48 is attached to the lower surface of the resin case 47a by a plurality of bolts 91. The heat sink 48 protrudes outside the electrical component box 40 through a through hole 41f formed in the inclined wall portion 41b. The heat sink 48 has a base portion 48a, a plurality of fins 48b protruding downward and rearward (-X side) from the base portion 48a, and a pair of flange portions 48c protruding from both sides of the base portion 48a in the left-right direction Y. The base portion 48a is in contact with the heat-generating component among the electrical components 72 attached to the substrate 71 through a through hole 47c formed in the resin case 47a. The base portion 48a closes the through hole 41f formed in the inclined wall portion 41b from the inside of the electrical component box body 41. The pair of flange portions 48c are fixed to the resin case 47a by a plurality of bolts 91.

[0035] The plurality of fins 48b are rectangular plate-shaped with their plate surfaces facing the left-right direction Y. The plurality of fins 48b are arranged side by side at intervals in the left-right direction Y. The plurality of fins 48b project downward and rearward (-X side) from the through hole 41f formed in the inclined wall portion 41b to the outside of the electrical component box 40. In Embodiment 1, the heat sink 48 is attached to the inclined wall portion 41b via the resin case 47a, so that the plurality of fins 48b project in a direction inclined in the front-rear direction X with respect to the vertical direction Z. Thereby, the air flow generated by the blower 15 can be hardly obstructed by the plurality of fins 48b. When the air sent by the blower 15 contacts the plurality of fins 48b, the heat generated in the first electrical component 70 can be released from the plurality of fins 48b to the air. Thereby, the first electrical component 70 can be cooled.

[0036] A frame-shaped seal member 81 is provided between the resin case 47a and the heat sink 48. The frame-shaped seal member 81 seals between the resin case 47a and the heat sink 48. The frame-shaped seal member 81 is configured by combining a pair of first seal members 81a extending in the direction in which the inclined wall portion 41b inclines and a pair of second seal members 81b extending in the left-right direction Y in a rectangular frame shape. The frame-shaped seal member 81 is elastically deformable. The material constituting the frame-shaped seal member 81 is, for example, urethane and an EPDM (Ethylene Propylene Diene Methylene) material (ethylene propylene diene rubber).

[0037] The through hole 41f formed in the inclined wall portion 41b is sealed by the frame-shaped seal member 81 and the frame-shaped seal member 82. Thereby, the intrusion of the refrigerant 19 into the electrical component box 40 from the through hole 41f is suppressed. Note that the first electrical component 70, the substrate holding member 47, and the heat sink 48 are rarely removed after being fixed to the electrical component box main body 41. Therefore, the frame-shaped seal member 81 and the frame-shaped seal member 82 are less likely to deteriorate, and the sealing performance of the through hole 41f is less likely to be impaired.

The materials constituting the respective seal members 80a, 80b, 80c, 80d of the frame-shaped seal member 80 are, for example, urethane and EPDM (Ethylene Propylene Diene Methylene) material (ethylene propylene diene rubber), etc.

[0046] Next, the elastic deformation portions 43, 44, 45, 46 will be described in more detail. In the following description, the elastic deformation portion 43 among the elastic deformation portions 43, 44, 45, 46 will be described as a representative, and the description of the same configuration as that of the elastic deformation portion 43 for the elastic deformation portions 44, 45, 46 may be omitted.

[0047] FIG. 8 is a perspective view showing a part of the electrical component box body 41 and is a partially enlarged view of FIG. 5. FIG. 9 is an exploded cross-sectional view showing a part of the electrical component box 40. In FIGS. 5, 8, and 9, the lid body 42 is not fixed to the electrical component box body 41, and the elastic deformation part 43 is shown in a state where it is not elastically deformed. FIG. 6 shows a state where the lid body 42 is fixed to the electrical component box body 41 and the elastic deformation part 43 is elastically deformed. In the following description, unless otherwise specified, the description of the elastic deformation part 43 shall be about the state where the lid body 42 is fixed to the electrical component box body 41, that is, the state where the elastic deformation part 43 is elastically deformed.

[0048] As shown in FIGS. 6, 8, and 9, when viewed from above, the elastic deformation part 43 protrudes from the edge of the opening 41h toward the inside of the opening 41h. The elastic deformation part 43 protrudes from the edge of the opening 41h toward the front side (+X side). As shown in FIGS. 8 and 9, in the state where the lid body 42 is not fixed to the electrical component box body 41 and is not elastically deformed, the elastic deformation part 43 extends in a direction inclined with respect to the vertical direction Z with respect to the front-rear direction X from the edge of the opening 41h. In the state where it is not elastically deformed, the elastic deformation part 43 protrudes from the edge of the opening 41h in a direction that is located on the upper side as it goes toward the front side. That is, in the state where it is not elastically deformed, the elastic deformation part 43 is also separated from the opening 41h in the vertical direction Z as it is separated from the edge of the opening 41h in the front-rear direction X. In the state where the elastic deformation part 43 is not elastically deformed, the inclination θ of the direction in which the elastic deformation part 43 protrudes with respect to the front-rear direction X is, for example, about 5° or more and 30° or less. As shown in FIG. 6, in Embodiment 1, the elastic deformation part 43 protrudes along the lower surface of the sealing material 80a in the front-rear direction X from the edge of the opening 41h in the state where the lid body 42 is fixed to the electrical component box body 41.

[0049] In Embodiment 1, the elastic deformation portion 43 is indirectly in contact with the lid body 42 in a state of being elastically deformed downward. In the present disclosure, "a certain object is indirectly in contact with another object" means that a certain object is disposed with another member interposed therebetween with respect to the other object, and the other member is in contact with the certain object and the other object. In Embodiment 1, the elastic deformation portion 43 is disposed with the sealing material 80a of the frame-shaped sealing member 80 interposed therebetween in the vertical direction Z with respect to the top plate portion 42a of the lid body 42, and the sealing material 80a is in contact with the top plate portion 42a and the elastic deformation portion 43. Thereby, the elastic deformation portion 43 is indirectly in contact with the lid body 42 via the sealing material 80a.

[0050] The elastic deformation portion 43 is in contact with the lower surface of the sealing material 80a. The elastic deformation portion 43 applies an upward force F to the sealing material 80a. Thereby, the elastic deformation portion 43 presses the sealing material 80a against the lid body 42. More specifically, the elastic deformation portion 43 presses the sealing material 80a against the lower surface of the top plate portion 42a. The elastic deformation portion 43 applies an upward force F to the lid body 42 by applying an upward force F to the sealing material 80a.

[0051] The elastic deformation portion 43 has a leaf spring portion 43a and a bent portion 43b. The leaf spring portion 43a projects in the front-rear direction X from the edge of the opening 41h. As shown in FIG. 8, the leaf spring portion 43a is in the shape of a rectangular plate extending in the left-right direction Y. As shown in FIG. 6, the upper plate surface of the leaf spring portion 43a is in contact with the lower surface of the sealing material 80a. Thereby, the leaf spring portion 43a is indirectly in contact with the lid body 42 via the sealing material 80a. The leaf spring portion 43a is elastically deformable in the vertical direction Z with the edge of the opening 41h as a fulcrum. The leaf spring portion 43a applies an upward force F to the lid body 42 via the sealing material 80a.

[0052] The upper plate surface of the leaf spring portion 43a is the flat portion 43d. The flat portion 43d is in indirect contact with the lid body 42 via the sealing material 80a. In Embodiment 1, in a state where the lid body 42 is fixed to the electrical component box main body 41, the flat portion 43d is a plane orthogonal to the vertical direction Z. The flat portion 43d applies an upward force F to the lid body 42 via the sealing material 80a. As shown in FIG. 9, in a state where the lid body 42 is fixed to the electrical component box main body 41, the flat portion 43d is an inclined surface inclined at an angle θ with respect to a plane (XY plane) orthogonal to the vertical direction Z.

[0053] As shown in FIG. 6, the bent portion 43b is connected to the tip of the leaf spring portion 43a in the front-rear direction X. In Embodiment 1, the bent portion 43b is connected to the front end (+X side) of the leaf spring portion 43a. The bent portion 43b is bent downward with respect to the leaf spring portion 43a. Note that "the bent portion 43b is bent downward with respect to the leaf spring portion 43a" means that the bent portion 43b is bent with respect to the leaf spring portion 43a so as to be located below the leaf spring portion 43a. In Embodiment 1, the bent portion 43b is bent downward from the tip of the leaf spring portion 43a and then folded back to the rear side (-X side). The bent portion 43b is located below the leaf spring portion 43a. A gap is provided between the bent portion 43b and the leaf spring portion 43a in the vertical direction Z. The bent portion 43b is disposed farther below the top plate portion 42a of the lid body 42 than the leaf spring portion 43a.

[0054] The connection portion 43c between the leaf spring portion 43a and the bent portion 43b is rounded. When viewed in the left-right direction Y, the connection portion 43c has an arc shape that protrudes forward (+X side). The connection portion 43c is the tip portion of the elastic deformation portion 43 in the front-back direction X. The connection portion 43c is the front end portion of the elastic deformation portion 43. When viewed in the vertical direction Z, the connection portion 43c is disposed at a position overlapping the sealing material 80a. The connection portion 43c is positioned away from both end portions of the sealing material 80a that the elastic deformation portion 43 contacts in the front-back direction X in the front-back direction X. The connection portion 43c is positioned away from the inner edge of the frame-shaped sealing member 80 toward the rear side (-X side). When viewed in the vertical direction Z, the connection portion 43c is positioned between the inner edge and the outer edge of the frame-shaped sealing member 80.

[0055] As shown in FIG. 9, the distance L in the vertical direction Z between the upper end portion of the elastic deformation portion 43 in a non-elastic deformed state and the edge of the opening 41h is larger than the thickness T in the vertical direction Z of the sealing material 80a. Thus, even if the frame-shaped sealing member 80 is not provided, by fixing the lid body 42 to the electrical component box main body 41, the top plate portion 42a contacts the elastic deformation portion 43, and the elastic deformation portion 43 can be elastically deformed downward.

[0056] The elastic deformation portion 44 is the same as the elastic deformation portion 43 except that it is provided symmetrically with respect to the elastic deformation portion 43 in the front-back direction X. The elastic deformation portion 44 presses the sealing material 80b against the lid body 42. As shown in FIG. 5, the elastic deformation portions 45 and 46 protrude in a direction from the edge of the opening 41h toward the outside of the opening 41h when viewed from above. The elastic deformation portion 45 protrudes from the edge of the opening 41h toward the left side (-Y side). The elastic deformation portion 46 protrudes from the edge of the opening 41h toward the right side (+Y side). The elastic deformation portion 45 and the elastic deformation portion 46 are provided symmetrically with respect to the left-right direction Y. The elastic deformation portion 45 presses the sealing material 80c against the lid body 42. The elastic deformation portion 46 presses the sealing material 80d against the lid body 42.

[0057] In addition, in Embodiment 1, the front-rear direction X in which the elastic deformation portions 43 and 44 protrude from the edge of the opening 41h and the left-right direction Y in which the elastic deformation portions 45 and 46 protrude from the edge of the opening 41h respectively correspond to the "second direction" that intersects the first direction.

[0058] As shown in FIG. 2, the connecting portion 31 protrudes to the right from the upper end portion of the electrical component box 40. The connecting portion 31 has a substantially rectangular parallelepiped shape that is flat in the vertical direction Z. The right end portion of the connecting portion 31 is located above the partitioning member 11c.

[0059] The holding member 60 is disposed inside the machine room 11b. The holding member 60 is fixed to the electrical component box 40 via the connecting portion 31 and the wall member 50. The holding member 60 is a member that holds the second electrical components 73 and 74. The holding member 60 has a first holding portion 61 and a second holding portion 62. In Embodiment 1, the first holding portion 61 and the second holding portion 62 are separate members from each other. The first holding portion 61 and the second holding portion 62 are sheet metal members. The first holding portion 61 and the second holding portion 62 are fixed to each other. The second electrical component 73 is held by the first holding portion 61. The second electrical component 74 is held by the second holding portion 62.

[0060] The second electrical components 73 and 74 are electrically connected to the substrate 71 of the first electrical component 70 by wiring (not shown). The second electrical component 73 is a sensor substrate to which a sensor (not shown) disposed in the machine room 11b is electrically connected. Unlike the substrate 71, no switch component is mounted on the second electrical component 73 which is a sensor substrate. The second electrical component 74 is a terminal block to which a plurality of wirings are connected.

[0061] The wall member 50 is located above the partitioning member 11c. The wall member 50 is located between the partitioning member 11c and the top panel (not shown) of the housing 11 in the vertical direction Z. The wall member 50 closes the gap between the partitioning member 11c and the top panel. Although not shown, a hole through which a wiring connecting the first electrical component 70 housed in the electrical component box 40 and the components disposed in the machine room 11b passes is formed in the wall member 50.

[0062] Next, the procedure for attaching the lid body 42 to the electrical component box body 41 will be described. As shown in FIG. 9, an operator who attaches the lid body 42 to the electrical component box body 41 brings the lid body 42 with the frame-shaped seal member 80 fixed thereto closer to the electrical component box body 41 from above. The operator brings the lid body 42 closer to the electrical component box body 41 until the flange portions 42c, 42d, 42e of the lid body 42 come into contact with the flange portions 41c, 41d, 41e of the electrical component box body 41, respectively, and fixes the flange portions 42c, 42d, 42e to the flange portions 41c, 41d, 41e with fastening members 90. At this time, before the flange portions 42c, 42d, 42e come into contact with the flange portions 41c, 41d, 41e, the seal members 80a, 80b, 80c, 80d constituting the frame-shaped seal member 80 come into contact with the elastic deformation portions 43, 44, 45, 46, respectively. When the lid body 42 is further brought closer to the electrical component box body 41 in this state, the elastic deformation portions 43, 44, 45, 46 are pushed against the top plate portion 42a of the lid body 42 via the frame-shaped seal member 80 and elastically deform downward. Therefore, by bringing the flange portions 42c, 42d, 42e into contact with and fixing them to the flange portions 41c, 41d, 41e, the lid body 42 can be attached to the electrical component box body 41 with the elastic deformation portions 43, 44, 45, 46 elastically deformed downward.

[0063] According to the first embodiment, an elastic deformation portion 43 that can be elastically deformed in the vertical direction Z is formed at the edge of the opening 41h of the electrical component box body 41. The elastic deformation portion 43 is indirectly in contact with the lid body 42 in a state of being elastically deformed downward on the side opposite to the upper side in the vertical direction Z, and applies an upward force F to the lid body 42. Therefore, it is possible to suppress the occurrence of a gap between the electrical component box body 41 and the lid body 42 and suppress the deterioration of the sealing performance of the electrical component box 40. Thereby, even when the refrigerant 19 leaked from the refrigerant pipe 18a in the machine room 11b flows into the blower room 11a, it is possible to suppress the leaked refrigerant 19 from entering the electrical component box 40. Thereby, it is possible to suppress the refrigerant 19 from causing problems to the first electrical component 70 housed in the electrical component box 40. Note that the refrigerant 19 leaked into the machine room 11b is, for example, in a gaseous state.

[0064] In particular, in Embodiment 1, a sealing material 80a is provided between the elastic deformation portion 43 and the lid body 42 in the vertical direction Z, and the elastic deformation portion 43 presses the sealing material 80a against the lid body 42. Therefore, even when compression set occurs in the sealing material 80a due to aging or the like, the state in which the sealing material 80a is in close contact with the elastic deformation portion 43 and the lid body 42 can be maintained. Further, even when the sealing material 80a peels off from the lid body 42, it is possible to suppress the occurrence of a gap between the sealing material 80a and the lid body 42. Thus, the sealing between the electrical component box main body 41 and the lid body 42 by the sealing material 80a can be suitably maintained. Therefore, it is possible to further suppress the deterioration of the sealing performance of the electrical component box 40.

[0065] Further, according to Embodiment 1, the elastic deformation portion 43 protrudes in the front-rear direction X intersecting the vertical direction Z from the edge of the opening 41h. The tip portion of the elastic deformation portion 43 in the front-rear direction X, that is, the connection portion 43c, is disposed at a position overlapping the sealing material 80a when viewed in the vertical direction Z. Therefore, it is possible to suppress the connection portion 43c of the elastic deformation portion 43 from directly contacting the top plate portion 42a of the lid body 42, and the elastic deformation portion 43 can be suitably brought into contact with the sealing material 80a. Thereby, it is possible to more suitably suppress the occurrence of a gap between the elastic deformation portion 43 and the sealing material 80a, and it is possible to more suppress the deterioration of the sealing performance of the electrical component box 40.

[0066] Further, according to Embodiment 1, the tip of the elastic deformation portion 43 in the front-rear direction X, that is, the connection portion 43c, is rounded. Here, in a state where the lid body 42 is not fixed to the electrical component box body 41, the connection portion 43c of the elastic deformation portion 43 is located above compared to the other portions of the elastic deformation portion 43. Therefore, when attaching the lid body 42 to the electrical component box body 41, the connection portion 43c first comes into contact with the sealing material 80a. At this time, if the connection portion 43c has a sharp corner, there is a risk that the corner will catch on the sealing material 80a and make it difficult to elastically deform the elastic deformation portion 43. Also, there is a risk that the sealing material 80a will be damaged by the corner. On the other hand, according to Embodiment 1, since the connection portion 43c is rounded, when attaching the lid body 42 to the electrical component box body 41, it is possible to prevent the connection portion 43c from catching on the sealing material 80a. Thereby, when attaching the lid body 42 to the electrical component box body 41, the elastic deformation portion 43 can be easily elastically deformed, and the lid body 42 can be easily attached to the electrical component box body 41. Also, damage to the sealing material 80a by the connection portion 43c can be suppressed, and it is possible to further suppress the sealing performance of the electrical component box 40 from being impaired.

[0067] Further, according to Embodiment 1, the tip of the elastic deformation portion 43 in the front-rear direction X is located away from both ends of the sealing material 80a in the front-rear direction X in the front-rear direction X. Therefore, even if there are variations in the dimensions of the sealing material 80a, etc., the elastic deformation portion 43 can be suitably brought into contact with the sealing material 80a.

[0068] Further, according to Embodiment 1, the elastic deformation portion 43 includes a leaf spring portion 43a that protrudes from the edge of the opening 41h in the front-rear direction X intersecting the vertical direction Z and applies an upward force F to the lid body 42, and a bent portion 43b that is connected to the tip of the leaf spring portion 43a in the direction in which the leaf spring portion 43a protrudes (front-rear direction X) and is bent downward with respect to the leaf spring portion 43a. Therefore, the tip of the elastic deformation portion 43 in the front-rear direction X, that is, the connection portion 43c, can be easily formed into a rounded shape.

[0069] Also, according to Embodiment 1, the elastic deformation portion 43 has a flat surface portion 43d that applies an upward force F to the lid body 42. Therefore, the area of the portion of the elastic deformation portion 43 that applies an upward force F to the lid body 42 can be increased, and it is easier to further suppress the sealing performance of the electrical component box 40 from being impaired. Further, in the configuration where the flat surface portion 43d contacts the sealing material 80a as in Embodiment 1, the area of the portion of the elastic deformation portion 43 that contacts the sealing material 80a can be increased, and the sealing material 80a can be preferably pressed by the elastic deformation portion 43. Thereby, it is possible to more preferably suppress the sealing performance of the electrical component box 40 from being impaired.

[0070] The effects of the elastic deformation portion 43 described above can be similarly obtained for the elastic deformation portions 44, 45, and 46. The elastic deformation portion 44 presses the sealing material 80b against the lid body 42. The elastic deformation portion 45 presses the sealing material 80c against the lid body 42. The elastic deformation portion 46 presses the sealing material 80d against the lid body 42. Thus, in Embodiment 1, the four elastic deformation portions 43, 44, 45, and 46 can press the four sealing materials 80a, 80b, 80c, and 80d that constitute the frame-shaped sealing member 80 against the lid body 42, respectively. Thereby, it is possible to preferably suppress the sealing performance of the electrical component box 40 from being impaired over the entire circumference of the opening 41h.

[0071] Here, the lid 42 is relatively often opened and closed with respect to the electrical component box body 41 for inspection of the first electrical component 70 and the like. Therefore, compared with the sealing performance of the through hole 41f formed in the inclined wall portion 41b to which the substrate holding member 47 and the heat sink 48, etc., which are rarely removed, are attached, the sealing performance of the opening 41h of the electrical component box body 41 is likely to be impaired. In the first embodiment, as described above, by suppressing the generation of a gap between the lid 42 and the electrical component box body 41 by the elastic deformation portions 43, 44, 45, 46, it is possible to suppress the impairment of the sealing performance of the opening 41h. Therefore, even if the lid 42 is opened and closed a plurality of times with respect to the electrical component box body 41, it is possible to suitably suppress the intrusion of the refrigerant 19 into the electrical component box 40. On the other hand, since the substrate holding member 47, the heat sink 48, etc. are rarely removed, the sealing performance of the through hole 41f formed in the inclined wall portion 41b is not easily impaired even without providing a structure such as the elastic deformation portions 43, 44, 45, 46. By adopting a structure capable of ensuring the sealing performance such as the elastic deformation portions 43, 44, 45, 46 only in the portion where the sealing performance is likely to be impaired in this way, it is possible to suppress the complication of the structure of the electrical component box 40 while suitably suppressing the intrusion of the refrigerant 19 into the electrical component box 40. Note that, also at the location where the through hole 41f is sealed, a structure similar to that of the elastic deformation portions 43, 44, 45, 46 may be adopted.

[0072] Also, in the first embodiment, the electrical component box 40 is disposed inside the blower chamber 11a. Since the refrigerant 19 is likely to leak inside the machine chamber 11b, by disposing the electrical component box 40 inside the blower chamber 11a, it is possible to further suppress the intrusion of the refrigerant 19 into the electrical component box 40. Also, as described above, the density of the refrigerant 19 in the gaseous state is greater than the density of air. Therefore, by disposing the electrical component box 40 in the upper portion inside the blower chamber 11a, even when the refrigerant 19 leaked inside the machine chamber 11b flows into the blower chamber 11a, the refrigerant 19 is suppressed from flowing downward by gravity and heading toward the electrical component box 40. Therefore, it is possible to more suitably suppress the intrusion of the refrigerant 19 into the electrical component box 40.

[0073] Second Embodiment. FIG. 10 is a cross-sectional view showing a part of the electrical component box 240 in Embodiment 2. In the following description, for components having the same configuration as those in the above-described embodiments, the description may be omitted by appropriately assigning the same reference numerals.

[0074] As shown in FIG. 10, in the electrical component box 240 of Embodiment 2, the elastic deformation portion 243 has a curved portion 243e that extends in a curved shape convex upward from the edge of the opening 41h. In Embodiment 2, the elastic deformation portion 243 consists of the curved portion 243e. The curved portion 243e is in an arc shape convex upward when viewed in the left-right direction Y. More specifically, the curved portion 243e is in a substantially semi-circular arc shape convex upward when viewed in the left-right direction Y. The curved portion 243e is in contact with the lower surface of the sealing material 80a. More specifically, the upper end portion of the curved portion 243e is in contact with the lower surface of the sealing material 80a. The curved portion 243e presses the sealing material 80a against the top plate portion 42a of the lid body 42. The curved portion 243e applies an upward force F to the lid body 42 via the sealing material 80a.

[0075] In Embodiment 2, other elastic deformation portions other than the elastic deformation portion 243 also have curved portions in the same manner as the elastic deformation portion 243. Other configurations of the electrical component box 240 are the same as those of the electrical component box 40 in Embodiment 1.

[0076] According to Embodiment 2, the elastic deformation portion 243 applies an upward force F to the lid body 42 via the curved portion 243e. Therefore, the portion of the elastic deformation portion 243 that contacts the sealing material 80a becomes the apex of the curved portion 243e that extends in a curved shape convex upward from the edge of the opening 41h. As a result, when the lid body 42 is attached to the electrical component box main body 41, the force applied to the elastic deformation portion 243 via the sealing material 80a is likely to be applied directly downward. Therefore, when the lid body 42 is attached to the electrical component box main body 41, the downward force required to elastically deform the elastic deformation portion 243 can be reduced. Therefore, the lid body 42 can be easily attached to the electrical component box main body 41.

[0077] Although the embodiments in the present disclosure have been described above, the present disclosure is not limited only to the configurations of the above-described embodiments, and the following configurations and methods can also be adopted.

[0078] The shape of the elastic deformation part is not particularly limited. The elastic deformation part may be made in any way. The elastic deformation part may be made of resin. In this case, the elastic deformation part and the electrical component box body may be integrally formed of resin. The number of elastic deformation parts is not particularly limited as long as it is one or more. For example, in the above-described Embodiment 1, some of the four elastic deformation parts 43, 44, 45, and 46 may not be provided. The elastic deformation part may be formed only at a location where there is a relatively high possibility of refrigerant intrusion among the edges of the opening of the electrical component box body.

[0079] The sealing material provided between the elastic deformation part and the lid body in the first direction (vertical direction Z) may be a sealing material made of any material as long as it can seal between the elastic deformation part and the lid body. For example, in the above-described Embodiment 1, the frame-shaped sealing member 80 may be integrally formed with four sealing materials 80a, 80b, 80c, and 80d to form one sealing material. A sealing material may not be provided between the elastic deformation part and the lid body in the first direction (vertical direction Z). In this case, the elastic deformation part elastically deforms and directly contacts the lid body, thereby sealing between the lid body and the electrical component box body. The electrical component box may be disposed at any location inside the housing of the heat exchange unit. For example, in the above-described Embodiment 1, the electrical component box 40 may be disposed inside the machine room 11b. The first direction in which the opening of the electrical component box body opens is not particularly limited and may be a direction other than the vertical direction. The second direction, which is the direction in which the elastic deformation part protrudes from the edge of the opening of the electrical component box body, may be a direction that intersects the first direction and does not necessarily have to be perpendicular to the first direction.

[0080] The heat exchange unit of the present disclosure may be an indoor unit of a refrigeration cycle device. The refrigeration cycle device provided with the heat exchange unit of the present disclosure may be any device that utilizes a refrigeration cycle in which a refrigerant circulates, and is not limited to an air conditioner. The refrigeration cycle device may be a heat pump water heater or the like.

[0081] As described above, each configuration and each method described in this specification can be appropriately combined within a range that does not conflict with each other.
