[0008] [1. Embodiment] [1.1.Configuration] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In each drawing, the symbol FR indicates the front when the storage device 1 is installed with its lower surface in contact with the installation surface, the symbol UP indicates the top of the storage device 1, and the symbol LH indicates the left of the storage device 1. In the following description, unless otherwise specified, each direction is along the direction of the storage device 1. Hereinafter, the state in which the storage device 1 is installed with its lower surface in contact with the installation surface will be referred to as the first posture.

[0009] FIG. 1 is a perspective view of a storage device 1 according to an embodiment of the present invention. The storage device 1 stores a detachable battery 100, converts the electricity stored in the battery 100 according to the user's operation, and supplies power to an electric device or the like outside the storage device 1 (Figure 3). The storage device 1 corresponds to the "electricity storage device" of the present disclosure.

[0010] 1, the storage device 1 includes a housing 10 having a substantially rectangular parallelepiped shape. The housing 10 includes a top surface, a bottom surface, a front surface, a rear surface, and a pair of side surfaces located on the left and right, all of which are flat. In the first position of the storage device 1, the bottom surface of the housing 10 becomes the bottom surface that contacts the installation surface. The housing 10 is not limited to a rectangular parallelepiped shape, and may have other shapes, such as a substantially cubic shape.

[0011] Fig. 2 is an exploded perspective view of the housing 10. In Fig. 2, members provided inside the housing 10, such as the accommodation mechanism 30 and the inverter unit 80, are omitted. 2, in the first posture of the storage device 1, the housing 10 includes an upper panel 12 that forms the upper surface, a lower panel 14 that forms the lower surface that becomes the bottom surface, a front panel 16 that forms the front surface, a rear panel 18 that forms the rear surface, and a pair of side panels 19 that form the left and right side surfaces. In this embodiment, all of the panels are made of a resin material, but this is not limiting, and at least one of the panels may be made of another material such as a metal material.

[0012] The upper panel 12 is formed to have a predetermined thickness dimension along the length of the storage device 1. The upper panel 12 is provided with an upper recess 11, which is recessed in a rectangular shape in plan view from the upper surface side toward the lower surface side at approximately the center thereof. The upper recess 11 is provided with an upper opening 13, which is a through-hole that is approximately rectangular in plan view, at approximately the center of the bottom surface thereof.

[0013] A lid 20 having a rectangular shape in a plan view is provided on the top panel 12. The lid 20 is rotatably fixed to the edge of the top recess 11 located on the rear side of the top panel 12. The lid 20 can be rotated by a user to cover the entire top recess 11 and the top opening 13 and can also be opened. In the top panel 12, the top surface of the lid 20 forms most of the top surface of the housing 10. The cover 20 has a lower surface facing the upper opening 13, on which a bulging portion 21 is formed by substantially the entire lower surface bulging toward the upper opening 13 (FIG. 3).

[0014] A plurality of legs 17 protruding outward are provided on the lower surface of the lower panel 14. In the first position, the storage device 1 is supported by these legs 17. In the first position, the lower panel 14 is positioned vertically downward in the up-down direction of the housing 10.

[0015] 1, a user interface unit 22 is provided on the front panel 16 at a position located on the front surface of the housing 10 and closer to the upper surface than the lower surface. The user interface unit 22 is equipped with LEDs (Light Emitting Diodes) and has an area for displaying the operating state of the storage device 1, the remaining energy of the battery 100, etc., and an operation area in which operators are provided to receive operations from the user, such as instructions to switch the operating state of the storage device 1. The user interface unit 22 functions as a display unit and also functions as an operation unit that allows the user to input predetermined operations to the storage device 1.

[0016] An AC power output terminal 24 and a DC power output terminal 26 are provided on the front panel 16 below the user interface unit 22. The AC power output terminal 24 and the DC power output terminal 26 supply AC power and DC power via external terminals connected to them, respectively. The front panel 16 may also be provided with an AC power input terminal and a DC power input terminal. The front panel 16 may be provided with a cover member that covers the controls, the AC power output terminal 24, and the DC power output terminal .

[0017] A front air intake 23, which is a through-hole, is provided in front panel 16 at a position on the front surface of housing 10, closer to the lower surface than the upper surface. This front air intake 23 is formed in the shape of an elongated hole extending along the left-right direction of housing 10, and is provided with multiple louvers.

[0018] 2, rear panel 18 is provided with rear exhaust port 25, which is a through-hole. In this embodiment, rear exhaust port 25 is formed in a rectangular shape and is provided at a position closer to the upper surface side of housing 10 than to the lower surface side. Rear exhaust port 25 is provided with a plurality of louvers. At least one of the front panel 16 and the rear panel 18 is not limited to being made of one member, but may be made of two or more members.

[0019] On the front panel 16 and the rear panel 18, linear handles 28 extending along the left-right direction of the housing 10 are provided at positions closer to the upper side of the housing 10 than to the lower side (FIG. 3). The handles 28 on the front panel 16 are formed by hollowing out the front panel 16 from the front side to the rear side of the housing 10, and the handles 28 on the rear panel 18 are formed by hollowing out the rear panel 18 from the rear side to the front side of the housing 10. This allows each of the handles 28 to be provided without protruding from the respective sides of the housing 10. This makes it possible to improve the design and operability of the storage device 1. A user can carry or set up the storage device 1 by grasping these handles 28. The handle 28 is not limited to the rod-like shape described above that allows the user to grip the entire circumference, but may have other shapes such as grooves that provide a handhold for the user.

[0020] 1 and 2, the upper end of the front panel 16 is connected to the front end of the upper panel 12, and the upper end of the rear panel 18 is connected to the rear end of the upper panel 12. The lower end of the front panel 16 is connected to the front end of the lower panel 14, and the lower end of the rear panel 18 is connected to the rear end of the lower panel 14. As a result, the upper panel 12, the lower panel 14, the front panel 16, and the rear panel 18 are connected to one another so as to form a rectangular frame when viewed from the left and right of the housing 10.

[0021] This allows the panels to reinforce each other, thereby improving the strength of the storage device 1. In addition, the front panel 16 and rear panel 18, on which the handle 28 is provided, are fixed to the top panel 12 and bottom panel 14, respectively, ensuring the strength of the storage device 1 when a user carries the storage device 1 by holding the handle 28. In this embodiment, the panels are connected to each other by fastening members such as screws.

[0022] Each of the side panels 19 is a rectangular plate-like member in a plan view. An engagement piece that protrudes from one of the planar sides is provided on each edge of the side panel 19. Each of the side panels 19 is fixed to the top panel 12, the bottom panel 14, the front panel 16, and the rear panel 18 by engaging the engagement piece from the left and right with an engagement groove provided in each of these panels. This makes it possible to easily form the housing 10 in the storage device 1. In addition, in the storage device 1, the top panel 12, the bottom panel 14, the front panel 16, and the rear panel 18 can be reinforced by attaching each of the side panels 19. However, the present invention is not limited to this, and each of the side panels 19 may be fixed to each other using a fastening member.

[0023] In this way, the storage device 1 with improved strength of the housing 10 is not limited to the first posture in which the bottom surface is installed as the bottom surface in contact with the installation surface, but can also be installed with the top surface, rear surface, and each of the left and right side surfaces as the bottom surface. This allows the installation posture of the storage device 1 to be changed depending on the user's purpose.

[0024] Fig. 3 is a vertical cross-sectional view of the storage device 1 taken along plane III shown in Fig. 1. Plane III is an imaginary plane passing through approximately the center of the storage device 1 in the left-right direction. 3, a storage mechanism 30 that holds the battery 100 is provided inside the housing 10. The storage mechanism 30 is disposed approximately in the center of the housing 10 in the front-to-rear direction, and is located directly below the top opening 13.

[0025] 3, the accommodation mechanism 30 accommodates the battery 100 and is electrically connected to the battery 100. The accommodation mechanism 30 includes a battery case 32. The battery case 32 is a container made of, for example, resin, that accommodates and holds the battery 100. The battery case 32 is formed in a substantially rectangular parallelepiped shape with its longitudinal direction extending along the up-down direction of the housing 10. The battery case 32 is located at the bottom of the housing 10 and includes a bottom 40 that forms a rectangular bottom surface in a plan view, and side walls 48 that rise from each side of the bottom 40.

[0026] The battery case 32 has a rectangular access opening 31 that opens over the entire top end surface. The access opening 31 is arranged at a position that overlaps with the top opening 13 in a plan view of the housing 10. The battery case 32 arranged in this manner is located approximately in the center of the housing 10 in the left-right direction. The battery case 32 is arranged at a predetermined distance from each of the side panels 19.

[0027] A plurality of case-side bosses 38 are provided on the bottom 40 of the battery case 32, protruding outward from the battery case 32 and toward the bottom of the housing 10. Each of the case-side bosses 38 has a cylindrical tip end surface with a circular shape. The battery case 32 corresponds to the "accommodation section" in the present disclosure.

[0028] The lower panel 14 is provided with a plurality of panel-side bosses 29 that protrude toward the upper part of the housing 10. Each of the panel-side bosses 29 is formed in the shape of a column with a circular tip surface. Each of the panel-side bosses 29 is disposed at a position corresponding to each of the case-side bosses 38 in a plan view of the housing 10. Each of the panel-side bosses 29 and each of the case-side bosses 38 are connected and fixed to each other by fastening members such as screws, with their tip surfaces abutting each other. As a result, the battery case 32 is spaced apart from the lower panel 14 and disposed above the lower panel 14 .

[0029] The housing mechanism 30 includes a case-side connection terminal 54. The case-side connection terminal 54 is a male terminal formed so as to be connectable to the battery 100. The case-side connection terminal 54 is disposed at the bottom of the battery case 32.

[0030] The battery 100 is a substantially rectangular parallelepiped member that houses a power storage unit such as a battery cell inside. Each of a pair of end faces located in the longitudinal direction of the battery 100 is rectangular in plan view. The battery 100 is provided so as to be detachable from the accommodation mechanism 30 and the accommodation device 1. The battery 100 is a heat-generating member that generates heat as the accommodation device 1 is driven. The battery 100 corresponds to the "power storage unit" of the present disclosure.

[0031] When storing the battery 100 in the storage device 1, the user opens the lid 20 and inserts the battery 100 from one end face side of the battery 100 into the top opening 13 and the loading / unloading opening 31 along the vertical direction of the housing 10. When the battery 100 is inserted into the battery case 32 until one end face of the battery 100 abuts against the bottom 40, the accommodation mechanism 30 connects the case-side connection terminal 54 to the battery 100. This electrically connects the battery 100 and the accommodation device 1.

[0032] An inverter unit 80 is provided behind the accommodation mechanism 30 in the front-rear direction of the housing 10. The inverter unit 80 includes an inverter 82 and a shroud 90. The inverter unit 80 corresponds to the "actuating device" of the present disclosure. The inverter 82 converts the power supplied from the battery 100 in response to a user operation and supplies the converted power to the AC power output terminal 24 and the DC power output terminal 26. The inverter 82 includes a rectangular substrate 84 having predetermined electrical components 86 mounted on both sides. The substrate 84 is arranged so that each flat surface faces in the front-to-rear direction of the housing 10. The electrical components 86 form predetermined electrical circuits such as an inverter circuit and a converter circuit. It should be noted that other electrical operating parts such as a DC-DC converter may be mounted on the substrate 84.

[0033] The inverter 82 is electrically connected to the case-side connection terminal 54 via a predetermined wiring. Therefore, when the case-side connection terminal 54 is connected to the battery 100, the power stored in the battery 100 is supplied to the inverter 82. The inverter 82 is a heat-generating member that generates heat as it is driven. The inverter 82 corresponds to the "operating portion" and the "fourth member" of the present disclosure. The shroud 90 is a covering member that covers the inverter 82 from the rear in the front-rear direction of the housing 10.

[0034] The inverter unit 80 is fixed inside the housing 10 by having the upper edge of the substrate 84 supported by an upper edge support member 87 and the lower edge of the substrate 84 supported by a lower edge support member 88 . The upper edge support member 87 is a linear member that curves in a U-shape toward the rear in the front-rear direction of the housing 10. Both ends of the upper edge support member 87 are fixed to the accommodation mechanism 30, and the approximate center in the longitudinal direction abuts against the board 84, thereby supporting the board 84 and the inverter unit 80.

[0035] The lower edge support member 88 is a linear member that is provided on the lower panel 14 and extends in the left-right direction of the housing 10. When viewed from the front side of the housing 10, the lower edge support member 88 is curved in a substantially M shape, and two peaks that protrude toward the top of the housing 10 abut against the board 84, thereby supporting the board 84 and the inverter unit 80. In this way, the inverter unit 80 is fixed to the housing 10.

[0036] The inverter 82 and the inverter unit 80 are arranged so that their longitudinal direction extends along the vertical direction of the housing 10, similar to the battery case 32. That is, the inverter 82 and the inverter unit 80 are provided so as to extend in the direction in which the battery 100 is inserted and removed. This allows the inverter 82 and the inverter unit 80 to be disposed inside the housing 10 by utilizing the space provided for the movement of the battery 100, and prevents the housing 10 from becoming large. The inverter 82 is disposed in the front-rear direction of the housing 10 so that the electrical components 86 mounted on one flat surface of the board 84 are spaced a predetermined distance from the battery case 32. One of the flat surfaces of the substrate 84 corresponds to the "second inner surface" of the present disclosure.

[0037] Fig. 4 is a perspective view of the inverter unit 80 as seen from the rear. For ease of explanation, the rear exhaust port 25 is indicated by a dashed line in Fig. 4. Fig. 5 is an exploded perspective view of the inverter unit 80. For convenience of explanation, Fig. 5 shows the rear panel 18. As shown in FIGS. 4 and 5, the shroud 90 includes a shroud body 92, a plurality of fans 94, a shroud cover 96, and a sheet member 98.

[0038] FIG. 6 is a perspective view showing the shroud body 92 and the inverter 82. As shown in FIG. The shroud main body 92 is an air guide member formed by providing a front side wall 110 and a rear side wall 112 that stand upright along the entirety of each side on both sides of a flat plate portion 99, which is a rectangular plate-like portion having approximately the same dimensions as the substrate 84. The shroud main body 92 is entirely made of a resin material. The front sidewall 110 is formed on the front side of the flat plate portion 99 facing the inverter 82 , and the rear sidewall 112 is formed on the rear side of the flat plate portion 99 facing the rear panel 18 . The front surface of the flat plate portion 99 corresponds to the "first inner surface" of the present disclosure.

[0039] The shroud body 92 covers the inverter 82 with the flat plate portion 99 facing the other flat surface of the substrate 84. In this case, the entire periphery of the front side wall 110 overlaps the periphery of the inverter 82. The front side wall 110 has a plurality of through-holes, or engagement openings 113, at predetermined locations. When the shroud main body 92 covers the inverter 82, the engagement openings 113 engage with engagement pieces 85 provided at predetermined locations on the periphery of the inverter 82. In this way, the shroud 90 is fixed to the inverter 82. Alternatively, an engagement hole may be provided in the inverter 82 and an engagement piece may be provided in the shroud main body 92 .

[0040] The front sidewall 110 has a height dimension that separates the flat plate portion 99 at a predetermined distance from the other flat surface of the substrate 84 and the electrical components 86 mounted on the inverter 82. In other words, a first space S1 is provided between the inverter 82 and the shroud main body 92, which is a space surrounded by one flat surface of the substrate 84, the front surface of the flat plate portion 99, and the front sidewall 110.

[0041] Shroud intake ports 91, which are through-holes, are provided at predetermined locations on the front side wall 110. The shroud intake ports 91 communicate between the first space S1 and the outside of the inverter unit 80. In this embodiment, two shroud intake ports 91 are provided at positions rising from the side located on the lower end side of the flat plate portion 99, and one shroud intake port 91 is provided at a position rising from the side located on the upper end side. The shroud intake port 91 corresponds to the "other communication hole" of the present disclosure.

[0042] 3, each of the shroud intake ports 91 located on the lower end side of the flat plate portion 99 is located below the bottom portion 40 of the battery case 32 in the up-down direction of the housing 10. In other words, when viewed from the front side of the housing 10, each of the shroud intake ports 91 located on the lower end side of the flat plate portion 99 is disposed at a position that does not overlap with the battery case 32.

[0043] The flat plate portion 99 is provided with a plurality of communication holes 93, which are through holes that connect the front side and the rear side. In this embodiment, three communication holes 93 are provided in a row along the left-right direction of the housing 10, approximately in the center of the flat plate portion 99. The communication holes 93 are formed in a circular shape in a plan view. The communication hole 93 corresponds to the "communication hole" of the present disclosure.

[0044] The flat plate portion 99 is provided with tubular portions 114 that stand up from the periphery of each of the communication holes 93. The tubular portions 114 have a cylindrical shape that surrounds the communication holes 93. When viewed in the longitudinal direction of the flat plate portion 99, each of the tubular portions 114 extends to a position where each of the shroud intake ports 91 is provided. In other words, each of the shroud intake ports 91 opens in a direction perpendicular to the extension direction in which the tubular portions 114 extend. The communicating hole 93 is not limited to a circular shape and may have other shapes. Similarly, the tubular portion 114 is not limited to a cylindrical shape and may have other shapes as long as it is tubular. The cylindrical portion 114 corresponds to the "cylindrical portion" in the present disclosure.

[0045] Figure 7 is a perspective view of the shroud body 92 as viewed from the rear. For ease of explanation, in Figure 7, the rear exhaust port 25 is indicated by a two-dot chain line, and the second exhaust port 97, the blower 94, and the cover rib 122 are indicated by a single-dot chain line. Also, in Figure 7, the first flow path F1, the second flow path F2, and the third flow path F3 are each indicated by an arrow. On the rear side of the flat plate portion 99, a plurality of main body ribs 120 are provided standing at predetermined positions within the area surrounded by the rear side wall 112. These main body ribs 120 have a rib shape and have a height dimension that is at least equal to or less than the height dimension of the rear side wall 112. Furthermore, at least one main body rib 120 has a height dimension that is lower than the other main body ribs 120. The shroud body 92 corresponds to the "first member" and "third member" of the present disclosure, and the body rib 120 corresponds to the "protrusion" of the present disclosure.

[0046] A plurality of fans 94 are attached to the rear surface of the shroud main body 92. The fans 94 are rotationally driven to promote airflow and blow air, primarily to cool heat-generating components of the accommodation device 1, such as the inverter 82 and the battery 100. The fans 94 of this embodiment are so-called sirocco fans that draw air from the center of rotation of an impeller and blow it out from predetermined locations radially of the impeller. The fans 94 include an impeller and a casing 130 that houses the impeller. The casing 130 has an intake opening for drawing in air on one side surface located in the direction of the rotation center of the impeller, and an outlet opening 131 for blowing air out on a side surface located in a direction intersecting the side surface.

[0047] In this embodiment, three fans 94 are provided in the shroud body 92, and each of the fans 94 is attached so that its intake opening overlaps with a corresponding one of the communication holes 93. Of these, the fan 94 closest to the left side of the housing 10 is arranged so that its outlet opening 131 faces the upper part of the housing 10, and the other fans 94 are arranged so that their outlet openings 131 face the lower part of the housing 10. The fans 94 in this embodiment are supported by a part of the body rib 120 and are attached to the shroud body 92 by fastening members such as screws. In the shroud body 92, these fans 94 are arranged side by side in the left-right direction and adjacent to each other. The blower 94 is not limited to a sirocco fan, and fans having other shapes and structures, such as an axial flow fan, may also be used. The fan 94 closest to the left side of the housing 10 corresponds to the "first fan" in this disclosure, and the other fans 94 correspond to the "second fan" in this disclosure.

[0048] A shroud cover 96 is attached to the shroud main body 92. The shroud cover 96 is a member having a flat surface that covers at least a portion of the rear surface of the shroud main body 92. In this embodiment, the shroud cover 96 is formed from resin. The shroud cover 96 is fixed to the shroud main body 92 by fastening members with its peripheral edge abutting against a tip of a portion of the rear side wall 112 and a tip of a portion of the main body rib 120. Between the shroud cover 96 fixed in this manner and the rear side of the shroud main body 92, a second space S2 is formed, which is surrounded by the flat plate portion 99, a part of the rear side wall 112, a part of the main body rib 120, and the shroud cover 96. The shroud cover 96 corresponds to the "second member" of the present disclosure.

[0049] A gap is formed between a predetermined location on the periphery of the shroud cover 96 attached to the shroud body 92 and a part of the body rib 120. This gap functions as a first exhaust port 95, which is an opening that connects the second space S2 with the outside of the inverter unit 80. The first exhaust port 95 opens toward the right of the housing 10. In this embodiment, the first exhaust port 95 is provided closer to the upper part of the housing 10 than to the lower part, and approximately in the center of the housing 10 in the left-right direction, as shown in FIG. The first exhaust port 95 corresponds to the "first flow path end" in this disclosure.

[0050] As shown in FIG. 5 , adjustment openings 133, which are through-holes, are provided at predetermined locations on the plane of the shroud cover 96. The adjustment openings 133 are arranged at positions overlapping with the respective fans 94 in a plan view, and are formed in substantially the same shape as the outer shape of the casings 130 provided for the respective fans 94. Therefore, in the front-rear direction of the housing 10, each of the casings 130 can be positioned at the same position as the plane of the shroud cover 96 or can protrude rearward beyond the plane. This allows the storage device 1 to reduce the thickness of the shroud cover 96 and ensure clearance inside the housing 10. Additionally, the storage device 1 allows the fans 94 to be larger, thereby improving cooling performance.

[0051] The adjustment opening 133 is covered by a sheet member 98. The sheet member 98 is a member formed in the shape of a thin sheet. This sheet member 98 covers the adjustment opening 133 as well as each of the fans 94 exposed from the adjustment opening, and prevents, for example, moisture entering from the rear exhaust port 25, condensed water, and the like from adhering to the fans 94. The sheet member 98 may be made of a heat insulating material such as polyethylene (PE). The sheet member 98 corresponds to the "blocking member" of the present disclosure.

[0052] In this way, the adjustment opening 133 is covered with the thin sheet-like sheet member 98, thereby separating the second space S2 from the space outside the shroud 90. Therefore, the shroud 90 can be closed without increasing the thickness dimensions of the shroud 90 and the shroud cover 96.

[0053] The sheet member 98 is attached to the shroud cover 96 so as to expose a portion of the adjustment opening 133. As a result, a second exhaust port 97, which is an opening that communicates the second space S2 with the outside of the inverter unit 80, is formed on the plane of the shroud cover 96 by a portion of the edge of the adjustment opening 133 and a predetermined location on the edge of the sheet member 98.

[0054] 4, in this embodiment, the second exhaust port 97 is provided at a position close to the left side surface of the housing 10 and opens toward the rear of the housing 10. The second exhaust port 97 is provided on the opposite side of the first exhaust port 95 in the up-down direction of the housing 10, with the fans 94 sandwiched between them. However, the second exhaust port 97 is not limited to this, and may be a through-hole that is provided independently in a position different from the adjustment opening 133 in the shroud cover 96 . The second exhaust port 97 corresponds to the "second flow path end" in this disclosure.

[0055] 7, a plurality of cover ribs 122 that stand up toward the shroud body 92 are provided on the flat surface of the shroud cover 96 that faces the shroud body 92. The cover ribs 122 have a rib shape and have a height dimension that is at least equal to or less than the height dimension of the rear side wall 112. In this embodiment, at least one cover rib 122 is formed so as to have a height dimension different from the other cover ribs 122.

[0056] When the shroud cover 96 is attached to the shroud body 92, some of the cover ribs 122 abut against the rear surface of the flat plate portion 99, and other cover ribs 122 are positioned spaced apart from the rear surface of the flat plate portion 99. Similarly, some of the main body ribs 120 abut against a flat surface of the shroud cover 96 that faces the shroud body 92, and other main body ribs 120 are positioned spaced apart from that flat surface.

[0057] In this way, the main body ribs 120 and the cover ribs 122 protrude into the second space S2, and a so-called labyrinth structure is formed by dividing the second space S2 into multiple locations. This provides multiple flow paths connecting the outlet openings 131 of the blowers 94 to the first exhaust port 95 or the second exhaust port 97.

[0058] In this embodiment, a first flow path F1 is provided which connects the blowing opening 131 of the blower 94 closest to the left side of the housing 10 with the first exhaust port 95, a second flow path F2 which connects the blowing openings 131 of each of the other blowers 94 with the second exhaust port 97, and a third flow path F3. Each of the first flow path F1, the second flow path F2, and the third flow path F3 forms a so-called meandering flow path that describes multiple curves in a plan view due to the main rib 120 and the cover rib 122. That is, each of the main rib 120 and the cover rib 122 functions as a flow path resistance in each of the first flow path F1, the second flow path F2, and the third flow path F3.

[0059] Furthermore, the main body ribs 120 and the cover ribs 122 are arranged in different numbers in each of the first flow path F1, the second flow path F2, and the third flow path F3. In addition, as described above, the main body ribs 120 and the cover ribs 122 have different heights. Therefore, the first flow path F1, the second flow path F2, and the third flow path F3 have different flow path lengths and flow path resistances arranged within the flow paths. In this way, by combining the shroud cover 96 and the shroud body 92, it is possible to form more complex flow paths with different flow path lengths and flow path resistances. The first flow path F1 corresponds to the "first flow path" in the present disclosure, and the second flow path F2 and the third flow path F3 correspond to the "second flow paths" in the present disclosure. The cover rib 122 corresponds to the "protrusion" in the present disclosure.

[0060] 5, a sealing member 140 is provided between the shroud cover 96 and the rear panel 18. In a plan view, the sealing member 140 surrounds both the shroud cover 96 and the rear exhaust port 25, and has one end abutting the shroud cover 96 in the front-to-rear direction of the housing 10, and the other end abutting the rear panel 18. In other words, the sealing member 140 is a sealant that separates the space located between the shroud cover 96 and the rear exhaust port 25 from other spaces inside the housing 10. By providing this sealing member 140, in the storage device 1, so-called short circuiting, in which air exhausted from the first exhaust port 95 or the second exhaust port 97 flows to the front side of the housing 10 relative to the inverter unit 80, is suppressed. Therefore, in the storage device 1, the air exhausted from the first exhaust port 95 or the second exhaust port 97 is more reliably exhausted from the rear exhaust port 25.

[0061] Next, the assembly procedure for the storage device 1 will be described. When assembling the storage device 1, first, the storage mechanism 30 is fixed to the bottom panel 14. Next, the front panel 16 and the inverter unit 80 are attached to the bottom panel 14. In this case, the front panel 16 is attached to the bottom panel 14 with the user interface unit 22, the AC power output terminal 24, and the DC power output terminal 26 already attached to each other. This allows the front panel 16, which includes many electrical components of the storage device 1, and the inverter unit 80 to be fixed to the bottom panel 14. After the front panel 16 and the inverter unit 80 are fixed to the bottom panel 14 of the storage device 1, the top panel 12 and the rear panel 18 are attached.

[0062] The upper panel 12, lower panel 14, front panel 16, and rear panel 18 attached in this manner are connected to each other so as to form a rectangular frame when viewed from the left and right of the housing 10, surrounding the components housed in the housing 10, such as the accommodation mechanism 30 and the inverter unit 80. Therefore, the panels reinforce each other, making it possible to improve the strength of the accommodation device 1.

[0063] [1.2. Operation] The operation of the storage device 1 configured as above will now be described. 8 and 9 are schematic diagrams showing the flow of cooling air in the storage device 1. Fig. 8 is a perspective view of the storage device 1 seen from the front side, and Fig. 9 is a perspective view of the storage device 1 seen from the rear side. In Figs. 8 and 9, arrows indicate air flowing inside the housing 10 by the fan 94. When the battery 100 is accommodated in the accommodation device 1 and the accommodation device 1 starts to operate from the battery 100, each of the fans 94 is driven. As a result, as shown in Figures 8 and 9, in the accommodation device 1, air is taken in from the outside to the inside of the housing 10 through the front air intake 23. The taken-in air passes below the battery case 32 and along the left and right sides.

[0064] Some of the air then passes between the inverter 82 and the side wall 48 of the battery case 32 located on the rear side of the housing 10. This allows some of the air to cool the circuit board 84, the electrical components 86 mounted on the flat surface of the circuit board 84 facing the battery case 32 of the inverter 82, and the battery 100. At this time, the side wall 48 functions as an air guide member that regulates the air to flow along the electrical components 86 and the circuit board 84.

[0065] This air rises to the upper end of the substrate 84 and is then drawn into the inverter unit 80 through a shroud intake port 91 provided on the upper end side of the shroud 90 . On the other hand, some of the air does not pass between the inverter 82 and the side wall 48, but is drawn into the inside of the inverter unit 80 through each of the shroud intake ports 91 provided at the lower end and each of the side edges of the shroud 90.

[0066] As described above, when viewed from the front side of the housing 10, the shroud intake ports 91 located on the lower end side of the shroud 90 are positioned so as not to overlap with the battery case 32. Therefore, the air drawn into the shroud intake ports 91 is prevented from being obstructed by the battery case 32.

[0067] In addition, each of the shroud intake ports 91 located on the lower end side of the shroud 90 is located on the opposite side of the loading / unloading port 31 for the battery case 32 in the vertical direction of the housing 10. Therefore, the air drawn into the shroud intake ports 91 is prevented from being obstructed by the accommodation mechanism 30 or the connecting structure between the upper panel 12 and the battery case 32.

[0068] The air drawn into the inverter unit 80 flows over the entire surface of the board 84, cooling the board 84 and the electrical components 86. After being taken into each of the fans 94, the air is exhausted to the outside of the inverter unit 80 and then to the outside of the housing 10 through the rear exhaust port 25. This allows the accommodation device 1 to efficiently cool heat-generating components such as the inverter 82 and the battery 100.

[0069] Next, the air flow inside the inverter unit 80 will be described in detail. The air drawn into the first space S1 is drawn from the tip of each of the cylindrical portions 114 into each of the communication holes 93, while cooling the board 84 and the electrical components 86 over the entire surface of the board 84. As described above, the cylindrical portions 114 are disposed at substantially the same positions as the shroud air inlets 91 in the front-rear direction of the housing 10. This allows each of the shroud air inlets 91 to flow along the board 84 and the electrical components 86 in the first space S1, while flowing a shorter distance before entering the cylindrical portion 114. Therefore, in the storage device 1, the air drawn in from each of the shroud air inlets 91 is prevented from diffusing and slowing down in the first space S1, and the board 84 and the electrical components 86 can be cooled more efficiently.

[0070] The air drawn into each of the communication holes 93 is taken into each of the blowers 94, and then flows through each of the first flow path F1, the second flow path F2, and the third flow path F3. As shown in Fig. 7, each of the first flow path F1, the second flow path F2, and the third flow path F3 is formed by each of the main body ribs 120 and each of the cover ribs 122 as a flow path that meanders at multiple locations in a plan view. In the shroud 90 having such a structure, the air that has flowed into the second space S2 flows in a serpentine manner along the first flow path F1, the second flow path F2, and the third flow path F3 in a plan view.

[0071] As described above, the other cover ribs 122 are disposed at a distance from the rear surface of the flat plate portion 99. Similarly, some of the main body ribs 120 abut against a flat surface of the shroud cover 96 facing the shroud main body 92, and other main body ribs 120 are disposed at a distance from that flat surface. In a shroud 90 having such a structure, the air flowing through each of the first flow path F1, the second flow path F2, and the third flow path F3 flows in a serpentine manner along the front-to-rear direction of the housing 10, in other words, along a direction perpendicular to the extension direction of the flow paths in a planar view.

[0072] As a result, the air flowing through the shroud 90 is decelerated in the second space S2 and is exhausted from the rear exhaust port 25 via the first exhaust port 95 and the second exhaust port 97. Therefore, in the accommodation device 1, the exhaust noise of the air that has cooled the inverter 82 and the battery 100 can be suppressed.

[0073] The first flow path F1, the second flow path F2, and the third flow path F3 are different from one another in terms of flow path length and the number of main body ribs 120 and cover ribs 122 that form the flow paths. This prevents the vibrations of the storage device 1 caused by the air flowing through the first flow path F1, the air flowing through the second flow path F2, and the air flowing through the third flow path F3 from resonating. Therefore, in the storage device 1, noise caused by driving the blower 94 can be reduced.

[0074] The air flowing through the first flow path F1 is exhausted from the first exhaust port 95, and the air flowing through the second flow path F2 and the air flowing through the third flow path F3 are exhausted from the second exhaust port 97. As described above, the first exhaust port 95 and the second exhaust port 97 are spaced apart from each other in the left-right and up-down directions of the housing. Furthermore, the first exhaust port 95 and the second exhaust port 97 open in different directions. That is, the air that cools predetermined components of the accommodation device 1, such as the inverter 82 and the battery 100, is divided and then exhausted in different directions. This prevents all of the air from flowing through the same flow path, reducing noise caused by driving the blower 94 and improving cooling efficiency.

[0075] The air exhausted from the first exhaust port 95 and the second exhaust port 97 is exhausted from the rear exhaust port 25. This allows the accommodation device 1 to efficiently cool heat-generating components such as the inverter 82 and the battery 100, and also reduce noise associated with the cooling.

[0076] The above-described embodiment is an example of one aspect of the present invention, and any modifications and applications are possible without departing from the spirit of the present invention.

[0077] In the above-described embodiment, the storage device 1 is provided with a detachable battery 100, but the storage device 1 may be provided with a power storage unit that is integrally provided therewith.

[0078] In the above-described embodiment, a plurality of identical fans 94 are provided, but this is not limiting, and the fans 94 may have different rotation speeds or structures. This suppresses resonance of the driving sounds emitted by the plurality of fans 94, and reduces noise associated with cooling the storage device 1.

[0079] In the above-described embodiment, each of the fans 94 is arranged in the second space S2, but this is not limiting and each of the fans 94 may be arranged in the first space S1. In other words, the shroud body 92 may be provided so that the inverter 82 and each of the fans 94 are arranged in the same space.

[0080] In the above-described embodiment, each of the first flow path F1, the second flow path F2, and the third flow path F3 is formed by the shroud main body 92 and the shroud cover 96 and is provided in the second space S2. However, this is not limiting, and at least one of the first flow path F1, the second flow path F2, and the third flow path F3 may be provided in a space different from the second space S2. Alternatively, at least one of the first flow path F1, the second flow path F2, and the third flow path F3 may be formed by the shroud main body 92 and a member different from the shroud cover 96.

[0081] Also, for example, each of the inverter 82, the shroud body 92, and the shroud cover 96 may be formed of multiple members.

[0082] In the above-described embodiment, the adjustment opening 133 is covered by the sheet member 98, but this is not limiting, and a sealant that seals the gap between each of the casings 130 and the adjustment opening 133 may be provided.

[0083] In the above-described embodiment, the accommodation device 1 takes in air through the front air intake port 23 and exhausts it through the rear exhaust port 25, but this is not limiting, and the air may be taken in through the rear exhaust port 25, passed through the inverter unit 80, and then exhausted through the front air intake port 23. In this case, in the shroud 90, the air flows from the second space S2 to the first space S1.

[0084] Furthermore, for example, sound absorbing material such as Thinsulate may be provided at predetermined locations on the inverter unit 80.

[0085] In the above-described embodiment, the storage device 1 and the storage mechanism 30 store the battery 100, but the present invention is not limited to this and may store other power storage units such as a capacitor.

[0086] Furthermore, for example, the storage device 1 of the present embodiment is a power supply device that supplies power to the outside of the device using the battery 100 housed inside the housing 10 as a power source, but is not limited to this, and may be a power consumption device that includes a power consumption unit formed integrally with the device, such as a light source, an audio output device, etc. Furthermore, for example, the storage device 1 may be formed so as to be able to charge the battery 100.

[0087] Furthermore, for example, the storage device 1 may include a sealing material that seals the gap between the storage mechanism 30 and the battery 100 stored in the storage mechanism 30 to make it liquid-tight, and may include a sealing structure formed by the sealing material. In this case, the storage device 1 may omit the lid 20.

[0088] In the above-described embodiment, the portable energy storage device is the battery 100 that stores electric power, but it is not limited to this and may be, for example, a hydrogen container that stores hydrogen used in a fuel cell, a so-called portable hydrogen tank, or other fuel storage device used for power generation. That is, the accommodation device 1 is not limited to a portable energy storage device, but may be one that detachably stores an object that stores an energy source such as fuel. In this case, the accommodation device 1 is provided with a mechanism for generating electricity from hydrogen.

[0089] Unless otherwise specified, the horizontal, vertical, and other directions and various shapes in the above-described embodiments include a so-called equivalent range that provides the same effects as those directions and shapes.
