[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In the drawings, the same or equivalent elements are designated by the same reference numerals, and redundant description will be omitted.

[0010] (First embodiment) An overview of an electric equipment system 1 according to a first embodiment will be described with reference to Figures 1 and 2. Figure 1 is a perspective view showing a state in which the electric equipment system 1 according to the first embodiment is in use. Figure 2 is a perspective view showing another state in which the electric equipment system 1 according to the first embodiment is in use.

[0011] The electrical equipment system 1 is fixed to, for example, a mounting surface of a structure (e.g., a desk top surface S1), and emits purified air onto the desk top surface S1 to purify the surrounding air. Furthermore, by fixing the electrical equipment system 1 in different orientations relative to the desk top surface S1, it is possible to emit purified air in different directions relative to the desk top surface S1. For example, in the usage state shown in FIG. 1, purified air is emitted from the desk top surface S1 in a direction along the desk top surface S1, and in the usage state shown in FIG. 2, purified air is emitted upward from the ceiling surface S1.

[0012] The electrical equipment system 1 includes a fixture 10 and a device main body 20.

[0013] The fixture 10 is fixed to the mounting surface of a structure. The structure is an object to which the electrical equipment system 1 is attached. Examples of the structure include a building, a desk, a chair, a bed, etc. The mounting surface of the structure is, for example, any surface of the structure, and is preferably a flat surface. For example, if the structure is a building, the mounting surface of the structure is, for example, the ceiling, floor, or side (wall) of the building, and if the structure is a desk, the mounting surface is, for example, the top or side of the desk. In other words, the fixture 10 is a member for fixing the device main body 20 facing upward, downward, horizontally, or at an angle inclined relative to these directions.

[0014] An overview of fixture 10 and device main body 20 will be described below with reference to Figures 3 and 4. Figure 3 is a perspective view of electrical equipment system 1 showing a state in which device main body 20 has been removed from fixture 10. Figure 4 is a view of electrical equipment system 1 as seen from the front.

[0015] In the following, for convenience of explanation, the thickness direction of a first wall portion 12 described below will be defined as the up-down direction, one surface 12a side of the first wall portion 12 described below will be defined as the upper side, the other surface 12b side of the first wall portion 12 described below will be defined as the lower side, the thickness direction of a second wall portion 13 described below will be defined as the front-rear direction, one surface 13a side of the second wall portion 13 described below will be defined as the front side, and the other surface 13b side of the second wall portion 13 described below will be defined as the rear side. Note that the above directions do not define the directions when the electric equipment system 1 is in use, but are defined to make the explanation of the electric equipment system 1 easier to understand.

[0016] 3, fixture 10 has a main body 11. Device main body 20 is attached to main body 11. Main body 11 includes a first wall 12, a second wall 13, and a pair of third wall 14.

[0017] The first wall 12 is a plate-like member whose thickness direction is in the vertical direction. The first wall 12 has one surface 12a and another surface 12b that face each other in the vertical direction. The one surface 12a is located on the upper side of the first wall 12 and faces the device main body 20. The one surface 12a is also referred to as the first mounting surface. The other surface 12b is located on the lower side of the first wall 12 and can be fixed to a mounting surface S1 of a structure. The other surface 12b is also referred to as the first fixing surface.

[0018] The second wall portion 13 is a plate-like member whose thickness direction is in the front-rear direction. The second wall portion 13 protrudes upward from the first wall portion 12 (one surface 12a). In this embodiment, the second wall portion 13 protrudes upward from the rear end of the one surface 12a.

[0019] The second wall portion 13 has one surface 13a and another surface 13b that face each other in the front-to-rear direction. The one surface 13a is located on the front side of the second wall portion 13 and faces the device main body 20. The one surface 13a is located on the minor angle side of the angle formed by the first wall portion 12 and the second wall portion 13. The one surface 13a is also referred to as the second mounting surface. The other surface 13b is located on the rear side of the second wall portion 13 and can be fixed to the mounting surface S1 of a structure. The other surface 13b is located on the major angle side of the angle formed by the first wall portion 12 and the second wall portion 13. The other surface 13b is also referred to as the second fixing surface.

[0020] The pair of third wall portions 14 face each other in the left-right direction, with the attached device main body 20 located between them. In this embodiment, one third wall portion 14 is located at the left end of the first wall portion 12 and the second wall portion 13. One third wall portion 14 is a surface located on the minor angle side of the angle formed by the first wall portion 12 and the second wall portion 13. The other third wall portion 14 is located at the right end of the first wall portion 12 and the second wall portion 13. The other third wall portion 14 is a surface located on the minor angle side of the angle formed by the first wall portion 12 and the second wall portion 13.

[0021] The third wall portion 14 is a plate-like member whose thickness direction is in the left-right direction. The third wall portion 14 has one surface 14a and another surface 14b that face each other in the left-right direction. The one surface 14a faces the device main body 20. The one surface 14a is also referred to as the third mounting surface. The other surface 14b is the surface opposite the surface facing the device main body 20.

[0022] The first wall portion 12 has through holes 12c through which fasteners (e.g., screws) to be attached to the attachment surface are passed. The through holes 12c are formed by penetrating the first wall portion 12. Two through holes 12c are provided in the first wall portion 12, spaced apart in the left-right direction.

[0023] The second wall portion 13 has through holes 13c through which fasteners (e.g., screws) attached to the mounting surface can pass. The through holes 13c are formed by passing through the second wall portion 13. Two through holes 13c are provided in the second wall portion 13, spaced apart in the left-right direction. The second wall portion 13 also has a through hole 13d through which a power cable (not shown) for supplying power to the device main body 20 can pass. The through hole 13d is located near the right end of the second wall portion 13.

[0024] 3 and 4, device main body 20 includes housing 21, a pair of fans 22, and ion generating unit 23. Device main body 20 is a blower that purifies air drawn into the device and then blows the purified air out. Note that device main body 20 includes ion generating unit 23, but is not limited thereto, and may not include ion generating unit 23.

[0025] 3, the housing 21 has a rectangular parallelepiped shape that is elongated in the left-right direction. The housing 21 has a rectangular first surface 21a, a second surface 21b, a third surface 21c, a fourth surface 21d, and a pair of fifth surfaces 21e.

[0026] The first surface 21a and the second surface 21b face each other in the vertical direction.

[0027] The first surface 21a is located on the upper side and is not covered by the fixture 10 but is exposed.

[0028] The second surface 21b is located on the lower side and faces the fixture 10 (first wall portion 12).

[0029] The third surface 21c and the fourth surface 21d face each other in the front-rear direction.

[0030] The third surface 21c is located on the front side and is not covered by the fixture 10 but is exposed.

[0031] The third surface 21c is formed with a pair of air inlets 24 and a pair of air outlets 25. In addition, an operating section 26 is provided on the third surface 21c.

[0032] The pair of suction ports 24 are formed on the third surface 21c at a distance in the left-right direction. The pair of suction ports 24 are lattice-shaped frames that are rotatable relative to the housing 21. This makes it possible to access the inside of the housing 21 by rotating the pair of suction ports 24 relative to the housing 21. A filter (not shown) is provided inside the pair of suction ports 24.

[0033] The pair of air outlets 25 are formed adjacent to each other in the center in the left-right direction on the third surface 21c. The pair of air outlets 25 are formed between the pair of air inlets 24.

[0034] The operation unit 26 accepts various operations of the device main body 20. The various operations of the device main body 20 include, for example, an operation to turn the power on and off, an operation to change the rotation speed of the fan 22, an operation to drive the ion generating unit 23, an operation to operate the timer, and the like.

[0035] In this embodiment, the third surface 21c functions as a discharge surface that blows out purified air.

[0036] The fourth surface 21d is located on the rear side and faces at least a part of the fixture 10 (second wall portion 13).

[0037] The pair of fifth surfaces 21e face each other in the left-right direction.

[0038] One fifth surface 21e is located on the left side and faces at least a part of the fixture 10 (one third wall portion 14).

[0039] The other fifth surface 21e is located on the right side and faces at least a part of the fixture 10 (the other third wall portion 14).

[0040] As described above, the device main body 20 is attached to the fixing device 10 with the second surface 21b facing the first wall portion 12, the fourth surface 21d facing the second wall portion 13, and the pair of fifth surfaces 21e facing the pair of third wall portions 14.

[0041] 4, first air passage 27 and second air passage 28 are formed inside housing 21. First air passage 27 is located on the left side inside housing 21, and connects one air inlet 24 and one air outlet 25. Second air passage 28 is located on the right side inside housing 21, and connects the other air inlet 24 and the other air outlet 25.

[0042] The pair of fans 22 are arranged at a distance in the left-right direction inside the housing 21. One fan 22 is arranged in a first air passage 27 and generates an airflow from one air inlet 24 toward one air outlet 25. The other fan 22 is arranged in a second air passage 28 and generates an airflow from the other air inlet 24 toward the other air outlet 25. The fans 22 are, for example, axial fans.

[0043] Ion generating unit 23 has first electrode 23a arranged in first air passage 27 and second electrode 23b arranged in second air passage .

[0044] By driving first electrode 23a, ions are added to the air flowing in first air passage 27, and the ions can be sent out together with the air from one of air outlets 25. Similarly, by driving second electrode 23b, ions are added to the air flowing in second air passage 28, and the ions can be sent out together with the air from the other air outlet 25.

[0045] The following describes the configuration for restricting movement of device body 20 by fixture 10. FIG. 5 is a perspective view showing protrusion 14c of fixture 10. FIG. 6 is a perspective view showing recess 29 of device body 20. FIG. 7 is a cross-sectional view of electrical equipment system 1 showing a state in which protrusion 14c is fitted into recess 29. FIG. 7 is a cross-sectional view taken along a plane perpendicular to the front-to-rear direction. FIG. 8 is a view of fixture 10 as seen from above. FIG. 9 is a view of electrical equipment system 1 as seen from the front, showing attachment of device body 20 in a state in which it is inverted relative to fixture 10. FIG. 10 is a perspective view showing claw portion 12d of fixture 10. FIG. 11 is a cross-sectional view of electrical equipment system 1 showing claw portion 12d. FIG. 11 is a cross-sectional view taken along a plane perpendicular to the left-to-right direction.

[0046] The fixture 10 further includes a first restricting portion and a second restricting portion.

[0047] The first restricting portion restricts the upward movement of the device main body 20 attached to the main body 11.

[0048] 5, the first restricting portions are a pair of protrusions 14c protruding in the left-right direction from the pair of third wall portions 14. The pair of protrusions 14c are formed on the corresponding third wall portions 14 along the front-rear direction.

[0049] As shown in Fig. 6, the device body 20 has a pair of recesses 29 that fit into the pair of protrusions 14c. The pair of recesses 29 are provided in a pair of fifth surfaces 21e. The recesses 29 are formed in the corresponding fifth surfaces 21e as grooves extending in the front-rear direction. The recesses 29 are formed in the corresponding fifth surfaces 21e, including the rear edge portions.

[0050] 7, when device main body 20 is attached to fixture 10, a pair of protrusions 14c fit into a pair of recesses 29, thereby restricting upward movement of device main body 20 relative to main body 11. The distance between one protrusion 14c and first wall 12 facing in the vertical direction is equal to the distance between the other protrusion 14c and first wall 12 facing in the vertical direction. Similarly, the distance between one recess 29 and second surface 21b facing in the vertical direction is equal to the distance between the other recess 29 and second surface 21b facing in the vertical direction.

[0051] The pair of protrusions 14c are configured so that they protrude in opposite directions in the left-right direction from the corresponding third wall portion 14. Specifically, one protrusion 14c protrudes to the right from one third wall portion 14, and the other protrusion 14c protrudes to the left from the other third wall portion 14.

[0052] As shown in FIG. 8, the front ends of the pair of protrusions 14c are located rearward of the front ends of the pair of third wall portions 14.

[0053] Furthermore, the distance between the pair of third wall portions 14 facing each other in the left-right direction is set to be approximately the same as or slightly larger than the left-right length of the device body 20. As a result, the pair of third wall portions 14 support the device body 20 by sandwiching it in the left-right direction, thereby restricting movement of the device body 20 in the left-right direction.

[0054] In the above configuration, the pair of protrusions 14c and the pair of recesses 29 are formed along the front-to-rear direction, so that when the pair of protrusions 14c are fitted into the pair of recesses 29, the movement of the device main body 20 in the vertical direction, more specifically, upward movement, can be restricted.

[0055] Furthermore, the pair of recesses 29 are formed to include the rear edge portions of the corresponding fifth surfaces 21e, so that the rear ends of the recesses 29 are open. This allows the protrusions 14c to be smoothly inserted into the recesses 29, making it easy to attach the device body 20 to the fixture 10.

[0056] Furthermore, the front ends of the pair of protrusions 14c are located rearward of the front ends of the pair of third wall portions 14. This allows the device body 20 (second surface 21b) to come into contact with (be supported by) the first wall portion 12 when the pair of protrusions 14c are fitted into the pair of recesses 29, making positioning easy.

[0057] 6, if the vertical dimension of device body 20 is defined as first dimension A1 and the vertical dimension from the bottom end of device body 20 to the pair of recesses 29 is defined as second dimension A2, then second dimension A2 is half of first dimension A1. As a result, device body 20 can be attached to fixture 10 even when rotated 180 degrees with the front-to-rear direction as the axial direction, and the orientation of device body 20 can be changed as desired by the user (see FIG. 9).

[0058] In this embodiment, a pair of protrusions 14c are formed on the fixture 10 and a pair of recesses 29 are formed on the device main body 20, but this is not limited to this, and one of the pair of protrusions 14c and the pair of recesses 29 may be provided on a pair of third wall portions 14 (fixture 10) and the other may be provided on a pair of fifth surfaces 21e (device main body 20).

[0059] Furthermore, in this embodiment, the pair of protrusions 14c and the pair of recesses 29 have shapes that extend in the front-rear direction, but this is not limited thereto. For example, the pair of protrusions 14c may be formed with locking protrusions such as claws that do not extend in the front-rear direction, and the pair of recesses 29 may be locking grooves into which the locking protrusions such as claws fit. Such a pair of protrusions can restrict movement in the front-rear direction in addition to the up-down direction, and can therefore also serve as a first restricting portion and a second restricting portion.

[0060] The second restricting portion restricts the device main body 20 attached to the main body 11 from moving forward.

[0061] As shown in FIGS. 10 and 11, the second restricting portion is a claw portion 12d that protrudes from the first wall portion 12 and is provided at a distance from the second wall portion 13 in the front-rear direction.

[0062] The claw portion 12d is provided at the front end portion of the first wall portion 12. The claw portion 12d is a protrusion that protrudes upward from the first wall portion 12. The claw portion 12d has a shape that protrudes upward from the first wall portion 12 and then bends forward.

[0063] 10, the claw portion 12d is provided in the center in the left-right direction of the first wall portion 12. The first wall portion 12 is provided with slits 12e on both sides in the left-right direction of the claw portion 12d. The slits 12e are formed in the first wall portion 12 so as to extend from the front edge portion to the rear side. This allows the claw portion 12d to bend in the up-down direction.

[0064] The distance between the claw portion 12d and the second wall portion 13 in the front-rear direction may be such that the device body 20 can be sandwiched and supported between the second wall portion 13 and the claw portion 12d. In this embodiment, the distance between the claw portion 12d and the second wall portion 13 in the front-rear direction is substantially the same as the distance between the third surface 21c and the fourth surface 21d of the device body 20. As a result, when the device body 20 is positioned between the claw portion 12d and the second wall portion 13, the claw portion 12d biases the device body 20 rearward, thereby restricting movement of the device body 20 in the front-rear direction, more specifically, forward.

[0065] The following describes how to fix fixture 10 to the mounting surface of the structure (top surface S1 of the desk).

[0066] A user fixes either the first wall portion 12 or the second wall portion 13 of the fixture 10 to the top surface S1 of the desk. For example, when fixing the first wall portion 12 to the top surface S1 of the desk, the first wall portion 12 is placed facing the top surface S1 of the desk and fastened to the through-hole 12c using a fastener such as a screw. When fixing the second wall portion 13 to the top surface S1 of the desk, the second wall portion 13 is placed facing the top surface S1 of the desk and fastened to the through-hole 13c using a fastener such as a screw.

[0067] While the above example illustrates a case where either the first wall portion 12 or the second wall portion 13 of the fixture 10 is fixed to a structure, the present invention is not limited to this, and both the first wall portion 12 and the second wall portion 13 may be fixed to a structure. For example, when fixing the fixture 10 to a corner between the ceiling and wall of a room, the first wall portion 12 may be fixed to the ceiling and the second wall portion 13 may be fixed to the wall.

[0068] Furthermore, the mounting surface of the structure to which fixture 10 is fixed does not necessarily have to be exposed. For example, fixture 10 may be fixed to a mounting surface within a wall so as to be embedded in the wall, and device main body 20 may be attached so that a portion of device main body 20 is exposed from the wall.

[0069] The method of attaching device main body 20 to fixture 10 will be described below.

[0070] The device body 20 is slid rearward while aligning the pair of recesses 29 of the device body 20 with the pair of protrusions 14c of the fixture 10. At this time, the claws 12d are pressed downward by the second surface 21b of the device body 20, causing them to bend downward. Furthermore, when the fourth surface 21d of the device body 20 is slid close to or in contact with the second wall 13, the device body 20 fits between the second wall 13 and the claws 12d. At this time, the claws 12d are restored from their bent state, and the claws 12d bias the device body 20 (third surface 21c) rearward, i.e., the device body 20 is attached to the fixture 10. To remove the device body 20 from the fixture 10, the device body 20 is slid forward while the claws 12d are bent downward.

[0071] (Second embodiment) An electric equipment system 1A of the second embodiment will be described with reference to Figures 12 and 13. Figure 12 is a perspective view showing the electric equipment system 1A of the second embodiment. Figure 13 is a cross-sectional view of the electric equipment system 1A of the second embodiment. Figure 13 is a view taken along a plane that passes through the latch mechanism 30 and is perpendicular to the left-right direction. The electric equipment system 1A of the second embodiment differs from the electric equipment system 1 of the first embodiment in that it is provided with a latch mechanism 30 instead of the claw portion 12d as a configuration for restricting forward movement of the device main body 20 attached to the main body portion 11. Below, only the differences from the first embodiment will be described, and a description of the same configuration as the first embodiment will be omitted.

[0072] 12 and 13, two latch mechanisms 30 are arranged spaced apart in the left-right direction. The latch mechanism 30 includes a connecting rod 31 (first member) and a connecting pipe 32 (second member). The connecting pipe 32 changes state between a locked state in which it holds the connecting rod 31 and an unlocked state in which it releases the holding of the connecting rod 31.

[0073] The connecting rod 31 is provided on the fourth surface 21d of the device body 20. A plurality of first engagement teeth (not shown) are formed on the side surface of the connecting rod 31. The connecting rod 31 protrudes rearward from the fourth surface 21d of the device body 20.

[0074] The connecting pipe 32 is provided on the second wall portion 13 of the fixture 10. An insertion hole 32a is formed in the connecting pipe 32, through which the connecting rod 31 is inserted. The insertion hole 32a is a hole that extends rearward from the second wall portion 13. A plurality of second engagement teeth (not shown) are formed in the insertion hole 32a.

[0075] When the connecting rod 31 is inserted into the insertion hole 32a, the first engagement teeth and the second engagement teeth mesh (engage), connecting the connecting rod 31 to the connecting pipe 32 and entering a locked state in which the connecting rod 31 is held. In the locked state, the first engagement teeth and the second engagement teeth allow the connecting rod 31 to slide in the direction (rearward) in which the connecting rod 31 is inserted into the connecting pipe 32, and restrict the connecting rod 31 from sliding in the direction (forward) in which the connecting rod 31 is pulled out of the connecting pipe 32. This restricts forward movement of the device main body 20. In the locked state, by further pushing the connecting rod 31 rearward relative to the connecting pipe 32, the mesh (engagement) between the first engagement teeth and the second engagement teeth is released, entering an unlocked state in which the holding of the connecting rod 31 is released.

[0076] The method of attaching device main body 20 to fixture 10 will be described below.

[0077] The device body 20 is slid rearward while aligning and inserting the pair of recesses 29 of the device body 20 into the pair of protrusions 14c of the fixture 10. Then, when the fourth surface 21d of the device body 20 is slid closer to the second wall portion 13, the connecting rod 31 is inserted into the connecting tube 32, and a locked state is established in which the connecting rod 31 is held; that is, the device body 20 is attached to the fixture 10. In this state, movement of the device body 20 in the direction (forward) in which the connecting rod 31 is pulled out of the connecting tube 32 can be restricted. To remove the device body 20 from the fixture 10, the device body 20 is pushed further rearward, which releases the holding of the connecting rod 31 and causes the device body 20 to be pulled out of the connecting tube 32.

[0078] In this embodiment, the connecting rod 31 is provided on the fourth surface 21d of the device main body 20, and the connecting pipe 32 is provided on the second wall portion 13 of the fixture 10, but this is not limited to this, and it is sufficient that one of the connecting rod 31 and the connecting pipe 32 is provided on the device main body 20 and the other is provided on the fixture 10.

[0079] The latch mechanism 30 has a connecting rod 31 and a connecting pipe 32, but is not limited to this and may be anything that can restrict the forward movement of the device main body 20. Furthermore, the method for releasing the connection between the connecting rod 31 and the connecting pipe 32 is not limited to the above and, for example, a latch release button or the like may be provided.

[0080] 13, when device body 20 is attached to fixture 10, it is located further forward than first wall 12. As a result, device body 20 protrudes from the front end surface of first wall 12, creating a space below device body 20. By utilizing this space, device body 20 can be grasped and slid relative to fixture 10, making it easy to attach and detach fixture 10 to and from device body 20.

[0081] Although the device main body 20 is a blower, it is not limited to this and may be, for example, a lighting device that emits light, a speaker that emits sound, or the like.

[0082] In the above configuration, the electrical equipment system 1 includes a fixture 10 fixed to a mounting surface (top surface S1 of a desk) of a structure, and an apparatus main body 20 detachable from the fixture 10. The fixture 10 has a main body 11 to which the apparatus main body 20 is attached, and a first restricting portion and a second restricting portion that restrict movement of the apparatus main body 20 attached to the main body 11. The main body 11 has a thickness direction in a first direction (vertical direction), and includes a first wall 12 having a first attachment surface (one surface 12a) on one side (upper side) in the first direction that faces the attached apparatus main body 20, and a second wall 13 that protrudes from the first wall 12 toward one side (upward) in the first direction, has a thickness direction in a second direction (front-rear direction) that is perpendicular to the first direction, and has a second attachment surface on one side (front side) in the second direction that faces the attached apparatus main body. A first fixing surface (other surface 12b) on the other side (lower side) in the first direction of the first wall portion 12, or a second fixing surface (other surface 13b) on the other side (rear side) in the second direction of the second wall portion 13, is fixed to the mounting surface (top surface S1 of the desk) so as to face the mounting surface (top surface S1 of the desk). The first restricting portion restricts movement of the device main body 20 attached to the main body portion 11 in one direction (upward) in the first direction, and the second restricting portion restricts movement of the device main body 20 attached to the main body portion 11 in one direction (forward) in the second direction.

[0083] This allows the first fixing surface (other surface 12b) or the second fixing surface (other surface 13b) to be fixed to the mounting surface of the structure (top surface S1 of the desk), thereby changing the orientation of the device body 20. Furthermore, even if the orientation of the device body 20 is changed, movement of the device body 20 in one of the first directions (upward) and one of the second directions (forward) can be restricted, so the device body 20 can be steadily supported.

[0084] The main body 11 further has a pair of third walls 14 that face each other in a third direction (left-right direction) that is perpendicular to the first direction and the second direction, and between which the attached device main body 20 is positioned in the third direction (left-right direction). This makes it possible to restrict movement of the device main body 20 in the third direction (left-right direction).

[0085] The electrical equipment system 1 further includes a pair of protrusions 14c protruding in a third direction (left-right direction), and a pair of recesses 29 into which the pair of protrusions 14c fit when the device body 20 is attached to the fixture 10. One of the pair of protrusions 14c and the pair of recesses 29 is a first restricting portion, and is provided on the pair of third wall portions 14, and the other of the one protrusion 14c and the pair of recesses 29 is provided on the device body 20.

[0086] Each of the pair of protrusions 14c is formed along the second direction (front-rear direction), and each of the pair of recesses 29 is formed as a groove extending in the second direction (front-rear direction), thereby restricting movement of the device body 20 in one direction (upward) in the first direction.

[0087] The first restricting portions are a pair of protrusions 14c, and the pair of protrusions 14c have ends (front ends) on one side in the second direction positioned on the other side in the second direction (rear side) of the ends (front ends) on one side in the second direction of the pair of third wall portions 14. This allows the device body 20 (second surface 21b) to come into contact with (be supported by) the first wall portion 12 when the pair of protrusions 14c are fitted into the pair of recesses 29, making positioning easy.

[0088] The dimension in the first direction (vertical direction) of device body 20 when attached to fixture 10 is defined as first dimension A1, and the dimension in the first direction (vertical direction) from the end (lower end) of device body 20 in the first direction to the pair of recesses 29 when attached to fixture 10 is defined as second dimension A2, and second dimension A2 is half of first dimension A1. This allows device body 20 to be attached to fixture 10 even when device body 20 is inverted around the second direction, so that the orientation of device body 20 can be changed to a desired direction by the user.

[0089] The second restricting portion is a claw portion 12d that protrudes from the first wall portion 12 and is provided at a distance in the second direction (front-rear direction) relative to the second wall portion 13. This restricts movement of the device body 20 in one direction (forward) in the second direction.

[0090] The electrical equipment system 1A further includes a latch mechanism 30 having a first member (connecting rod 31) and a second member (connecting pipe 32) that changes state between a locked state in which the first member (connecting rod 31) is held and an unlocked state in which the first member (connecting rod 31) is released from its hold. One of the first member (connecting rod 31) and the second member (connecting pipe 32) is a second restricting part and is provided on the second wall part 13, while the other of the first member (connecting rod 31) and the second member (connecting pipe 32) is provided on the device main body 20. This restricts movement of the device main body 20 in one direction (forward) in the second direction.

[0091] When device body 20 is attached to fixture 10, it protrudes further to one side (front side) in the second direction than first wall 12. This allows device body 20 to be grasped and slid relative to fixture 10 by utilizing the space formed on the other side (bottom side) of device body 20 in the first direction, making it easy to attach and detach fixture 10 to and from device body 20.

[0092] Each of the first wall portion 12 and the second wall portion 13 has through holes (through holes 12c and 13c) through which fasteners to be attached to the mounting surface (top surface S1 of the desk) can be passed. This makes it possible to easily attach the first wall portion 12 or the second wall portion 13 to the mounting surface (top surface S1 of the desk) of the structure.

[0093] The device body 20 is a blower.

[0094] The fixture 10 is used in an electrical equipment system 1 .
