Embodiments for Carrying out the Invention

[0017] A preferred embodiment of a blower device with a lighting function (hereinafter simply referred to as a blower device) according to the present invention will be described with reference to the drawings. Note that each of the following drawings is schematically illustrated, and the dimensional ratios and numbers on the drawings do not necessarily match the actual dimensional ratios and numbers.

[0018] FIG. 1 is a perspective view of the blower device as viewed from the lower surface (front side), FIG. 2 is a plan view, and FIG. 3 is a side view. In FIG. 3, a mounting member 50 to which the blower device 1 is attached is schematically shown.

[0019] As shown in FIGS. 1 and 2, the blower device 1 includes a base portion 3, a main body portion 5, and an arm portion 7 that connects the base portion 3 and the main body portion 5.

[0020] A blower 10 and a lighting unit 11 are mounted on the main body portion 5 (see FIGS. 4 and the like described later). The main body portion 5 blows out air and emits illumination light from the front side surface of the main body portion 5 (hereinafter referred to as the "main surface M1"). The outer diameter of the main body portion 5 is not limited, but as an example, it is 10 cm to 30 cm. The configuration of the main body portion 5 will be described later with reference to FIGS. 4 and the like.

[0021] As shown in FIGS. 1 and 3, the base portion 3 has a cylindrical portion 3a and a base 3b. The cylindrical portion 3a can accommodate circuit portions such as a power supply circuit, a drive circuit, and a control circuit. The outer diameter of the cylindrical portion 3a is arbitrary and can be appropriately designed according to the size of the blower device 1 and the like, but as an example, it is 2 cm to 10 cm.

[0022] The base portion 3 is attached to a predetermined mounting member 50 via a socket 3b. Figure 3 shows an example in which the socket 3b is fitted to a mounting member 50 provided on the ceiling 51. On the mounting member 50, the surface to which the base portion 3 is attached corresponds to the mounting surface S1.

[0023] The size of the nozzle 3b can be designed as appropriate according to the size of the blower 1, etc. Note that the method of mounting the blower 1 is not limited to the method via the nozzle; for example, other types of adapters such as hooks may be used. Whether the base 3 has a nozzle 3b is optional (see also Figures 7 and 8 described later).

[0024] Figure 3 is merely one example of how the blower 1 may be installed; the mounting member 50 may also be embedded in the ceiling 51. Furthermore, the installation location of the blower 1 is not limited to the ceiling 51. For example, the blower 1 may be installed on a duct rail or the like.

[0025] As shown in Figures 1 and 3, the arm portion 7 connects the main body portion 5 and the base portion 3. More specifically, the arm portion 7 has a flat plate portion 8 extending in a direction substantially perpendicular to the mounting surface S1, and a flat plate portion 9 formed by curving from the flat plate portion 8 and extending in a direction substantially parallel to the mounting surface S1, thus exhibiting an L-shape. The arm portion 7 is also made of a hollow member, through which wiring and other components that supply the power necessary for the blower 10 and the lighting unit 11 pass. As an example, the width of the arm portion is 1 cm to 5 cm, and the thickness is 0.3 cm to 3 cm.

[0026] The flat plate portion 8 corresponds to the "first part," and the flat plate portion 9 corresponds to the "second part."

[0027] As shown in Figure 3, the flat plate portion 8 of the arm portion 7 has a first connecting portion 8a connected to the side surface of the main body portion 5. The other flat plate portion 9 of the arm portion 7 has a second connecting portion 9a connected to the cylindrical portion 3a of the base portion 3.

[0028] In this embodiment, the first connecting portion 8a rotatably supports the main body portion 5 around a rotation axis A1 which is substantially parallel to the main surface M1 of the main body portion 5. The rotation axis A1 corresponds to the "first axis". The direction in which the rotation axis A1 extends corresponds to the direction in which the support column member 22, which will be described later, extends.

[0029] Furthermore, the second connecting portion 9a is rotatable around the direction in which the cylindrical portion 3a extends. That is, the second connecting portion 9a rotates around a rotation axis A2 that is substantially perpendicular to the mounting surface S1. As a result, the arm portion 7 is rotatable relative to the base portion 3 (see also Figure 2). The rotation axis A2 corresponds to the "second axis".

[0030] In this specification, "approximately orthogonal" is not limited to exactly 90°, but includes a range of 90° ± 10°, taking into account manufacturing tolerances, etc. Similarly, "approximately parallel" is not limited to exactly 0°, but includes a range of 0° ± 10°.

[0031] Thus, in the blower 1, the main body 5 can be rotated by the first connecting part 8a, and the arm part 7 can be rotated by the second connecting part 9a. The rotation axes (A1, A2) of both connecting parts (8a, 9a) intersect with each other. In the blower 1, rotational operation is possible by both connecting parts (8a, 9a), and there is a high degree of freedom in adjusting the orientation of the main surface M1 of the main body 5, making it easy to orient the main body 5 in the desired direction.

[0032] In this embodiment, the rotation axis A1 is approximately parallel to the main surface M1, and the rotation axis A2 is approximately perpendicular to the mounting surface S1, but the present invention is not limited to this. At the very least, by having the rotation axes A1 and A2 intersect with each other, it is possible to increase the degree of freedom in adjusting the orientation of the main body 5. From the viewpoint of facilitating intuitive operation by the user, it is preferable that the rotation axis A1 is approximately parallel to the main surface M1. Similarly, it is preferable that the rotation axis A2 is approximately perpendicular to the mounting surface S1.

[0033] Conventional known configurations can be used as the rotation mechanism for the first connecting portion 8a and the second connecting portion 9a. For example, both connecting portions (8a, 9a) may be configured to be rotatable via a disc-shaped member. Furthermore, a wiring passage for inserting wiring may be formed in the center of the disc-shaped member. Preferably, both connecting portions (8a, 9a) are rotatable in either clockwise or counterclockwise directions. The rotation angle of both connecting portions (8a, 9a) is set appropriately according to the routing of the wiring, etc.

[0034] Next, the configuration of the main body 5 will be described with reference to Figures 4 and 5. Figure 4 is a perspective view of the main body 5 in a disassembled state, viewed from the front, and Figure 5 is a perspective view of the main body 5 in a disassembled state, viewed from the rear. As shown in Figures 4 and 5, the main body 5 has a support part 15 that supports the blower 10 (not shown in Figures 4 and 5, see Figure 6), a front guard part 16 located in front of the support part 15, and a rear guard part 17 located behind the support part 15.

[0035] Figure 6 shows the blower 1 with the front guard section 16 and the rear guard section 17 removed. As shown in Figure 6, the front guard section 16 and the rear guard section 17 can be removed from the support section 15 while the blower 10 is supported by the support section 15. By removing the front guard section 16 and the rear guard section 17 while the blower 10 is supported by the support section 15, the user can easily perform maintenance such as cleaning the blower 10.

[0036] As shown in Figures 4 and 5, the support section 15 includes a housing section 20 located in the central region, a ring-shaped frame section 21 surrounding the housing section 20, a support column member 22, and a plurality of plate-like sections 23. The support column member 22 connects the side surface of the housing section 20 to the inner surface of the frame section 21. The plate-like sections 23 are arranged circumferentially spaced apart from the support column member 22 and connect the side surface of the housing section 20 to the inner surface of the frame section 21.

[0037] The housing 20 houses an LED board 11a on which multiple LEDs constituting the lighting unit 11 are arranged. The housing 20 also houses a board 20a that supports the motor that drives the blower 10 and the driver that lights up the lighting unit 11.

[0038] The lighting unit 11 is located in the center of the blower 10 and has a lighting cover 11b on its front side. The lighting cover 11b is attached to the front end of the housing 20. The housing 20 emits light from the lighting unit 11 through the lighting cover 11b. The lighting cover 11b is made of a material that is light-transmitting and light-diffusing.

[0039] As shown in Figures 5 and 6, a rotating shaft portion 20b is provided on the rear side of the housing portion 20 to rotatably support the blower 10. The blower 10 attached to the rotating shaft portion 20b is rotationally driven by a motor housed in the housing portion 20.

[0040] The support column member 22 is a hollow member, and wiring and other components necessary for supplying power to the blower 10 and lighting unit 11 are arranged inside. It is also possible to arrange the circuit section of the blower device 1 on the support column member 22.

[0041] As shown in Figure 4, the front guard section 16 has a ring outer wall 30, a ring inner wall 31, and a plurality of radially extending spokes 32. The ring inner wall 31 forms a through-hole 34 in which the lighting section 11 of the housing section 20 is located. That is, as shown in Figure 1, the lighting section 11 protrudes forward from the front guard section 16 through the through-hole 34. Light emitted from the lighting section 11 is emitted from the front surface (main surface M1) of the front guard section 16, and air is blown out from the blower 10.

[0042] As shown in Figure 5, the multiple spokes 32 are configured in two stages with respect to the direction of airflow. The intersecting of the spokes 32 in each stage facilitates the diffusion of air from the blower 10, which is preferable.

[0043] As shown in Figure 4, the rear guard portion 17 has a bottom wall 41 with multiple radially extending spokes and a wall portion 42 that rises forward from the bottom wall 41. In other words, the rear guard portion 17 has a shape that is recessed toward the rear, forming a space for housing the blower 10.

[0044] As shown in Figures 4 and 5, an engagement groove 15s is formed on the rear side of the frame portion 21 of the support portion 15, and engages detachably with an engagement pin 17p formed on the inner surface of the wall portion 42 of the rear guard portion 17. Although four engagement grooves 15s and engagement pins 17p are formed along the circumferential direction, the number of engagement grooves 15s and engagement pins 17p is not limited to a specific number. Furthermore, the support portion 15 may have engagement pins and the rear guard portion 17 may have engagement grooves.

[0045] Furthermore, multiple engagement pins 15p are formed on the front side of the frame portion 21 of the support portion 15, and these pins detachably engage with engagement grooves 16s formed on the outer ring wall 30 of the front guard portion 16. Although four engagement pins 15p and engagement grooves 16s are formed along the circumferential direction, the number of engagement pins 15p and engagement grooves 16s is not limited to a specific number. In addition, the support portion 15 may have engagement pins and the rear guard portion 17 may have engagement grooves.

[0046] Thus, the support portion 15 and the front guard portion 16 are configured to be detachable by an engagement structure of engagement pins and engagement grooves. Specifically, the user can remove the front guard portion 16 from the support portion 15 by gripping the support portion 15 and rotating the front guard portion 16 in the circumferential direction. The same applies to the support portion 15 and the rear guard portion 17. In other words, the main body portion 5 of the blower device 1 can be disassembled and assembled without the need for tools such as a screwdriver, making it easy for the user to perform tasks such as cleaning. It should be noted that this point merely describes a preferred configuration regarding the operation of the main body portion 5 and does not preclude the use of a fixing structure via screws or other components in the blower device 1.

[0047] Similarly, it is preferable that the housing portion 20 and the lighting cover 11b be configured to be detachable by an engagement structure of engagement pins and engagement grooves.

[0048] As described above, the main body 5 can be rotated to the desired direction by the first connecting part 8a and the second connecting part 9a. In the blower device 1, there is a high degree of freedom in adjusting the direction of the main body 5, and the blower 10 is supported by the support part 15 located in the middle of the main body 5, so that the user can perform tasks such as cleaning more easily.

[0049] Furthermore, as shown in Figure 6, it is preferable that the blower 10 is supported by a rotating shaft portion 20b that protrudes from the rear side of the support portion 15. This allows the blower 10 to be exposed so as to protrude from the support portion 15 when the rear guard portion 17 is removed, making it easier for the user to clean the blower 10.

[0050] From a similar viewpoint, it is preferable that the arm portion 7 of the blower 1 is composed of a single L-shaped member. This configuration facilitates the user's gripping of the main body portion 5, simplifies the disassembly and assembly of the main body portion 5, and simplifies the cleaning of the blower 10, etc. Furthermore, since it is a single L-shaped member, the number of parts of the blower 1 is reduced, which is also preferable.

[0051] [Alternative Embodiment] <1> Figures 7 and 8 are drawings showing another embodiment of the blower device 1 according to the present invention. As shown in Figure 7, the base part 3 is a so-called hook ceiling type and may have an adapter 3c and a protective cover 3d that protects the adapter 3c. Also, as shown in Figure 8, the base part 3 may have a terminal 3e that is installed on a duct rail. In the present invention, the shape of the base part 3 is arbitrary.

[0052] <2> In the above, the support portion 15 and the front guard portion 16 are configured to be detachable by an engagement structure of an engagement pin and an engagement groove, but the engagement structure of the support portion 15 and the front guard portion 16 is not limited to the above. For example, the support portion 15 and the front guard portion 16 may be engaged via an elastically deformable claw portion and an opening into which the claw portion is hooked. The same applies to the support portion 15 and the rear guard portion 17.

[0053] <3> The blower device according to the present invention is not limited to the configuration described above. [Explanation of Symbols]
