Description

[Technical field]

[0001] This invention relates to a lighting fixture with a blower that is placed on a wall surface such as a ceiling in a room and that integrates a blower that circulates indoor air with a lighting unit. [Background technology]

[0002] The blower with lighting function in Patent Document 1 has a blower in the center and a lighting unit around the blades, and the lighting unit brightens the room while the blower rotates to circulate air inside the room. In addition, the blower is fixed to a hinge so that it can rotate, so the angle can be adjusted by touching the blower.

[0003] However, the blower device in Patent Document 1 has front and rear guards that protect the front and rear of the blower, both of which change angle, and when tilted, small objects or fingers can easily get in between the mesh guards depending on the angle, which is not necessarily safe. Also, because the space between the rear and front guards is narrow, there is no space to insert a cleaning tool even if the front cover and the blower are removed. Therefore, there is a problem that it is difficult to clean the inner surface of the rear guard, and dust remains on the inner surface of the rear guard, and the dust is spread by the blower into the room, causing discomfort. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Publication No. 3231311 Summary of the Invention [Problem to be solved by the invention]

[0005] Therefore, the objective of this invention is to provide a lighting fixture with a blower that can be easily cleaned and maintained using a cleaning tool while ensuring safety even when the angle of the blower is changed. [Means for solving the problem]

[0006] In order to solve the above problems, a lighting fixture with a blower that can be attached to a wall surface is characterized in that it comprises an illumination unit that is annular in shape having a predetermined height and has light-emitting units made of LED elements arranged continuously along the inner peripheral wall, an outer cover unit that protrudes upward from the inner edge of the illumination unit, and an inner cover unit that exists within the storage space inside the annular illumination unit and outer cover unit, the inner cover unit having a rotatable blower therein and being pivotally supported so as to be tiltable relative to the illumination unit. Note that "wall surface" refers to the ceiling surface or wall inside a room.

[0007] It is also preferable that the inner cover portion has a removable mesh-like inner cover lid portion on the lower surface, has a side formed in a mesh pattern from the lower end to the upper end, and comprises an inner cover main body whose upper surface consists only of a retaining body and has an open space around it.

[0008] It is also preferable that the inner cover body of the inner cover part defines the accommodation space for the outer cover part so that the upper end is positioned higher than the lower end of the outer cover part when the inner cover body is rotated and inclined.

[0009] In addition, it is preferable that the inner cover portion comprises an inner cover main body having an inner cover groove portion, and an inner cover lid portion having a locking protrusion portion, the inner cover groove portion comprising an upper and lower guide portion that guides the locking protrusion portion in the vertical direction, and a left and right guide portion that is narrower than the upper and lower guide portions, the left and right guide portions comprising a straight portion in the depth direction of the inner cover portion, an inclined portion that is inclined in the left and right direction and upward of the inner cover portion, and a storage portion with a recessed shape. Effect of the Invention

[0010] According to the invention described in claim 1, the device is provided with an outer cover part that protrudes upward from the inner edge of the lighting part and exists separately from the inner cover part that supports the blower so that it can be tilted. Therefore, no matter how it is tilted, the outer cover is fixed and covers it, ensuring safety while widening the space inside the inner and outer covers to make it easier to use cleaning tools.

[0011] According to the invention described in claim 2, by providing a holder that holds the upper end of the inner cover, an open space is formed at the top, and by simply removing the inner cover lid and the blower, a cleaning tool can be inserted from the open end and the inner surface of the outer cover can be cleaned.

[0012] According to the invention described in claim 3, the upper end of the inner cover is positioned higher than the lower end of the outer cover, preventing the inner cover from rotating excessively and maintaining an open space on the upper surface of the inner cover, so that the open space is not exposed from the outer cover even when tilted. This allows for a larger cleaning space and safe use.

[0013] According to the invention described in claim 4, the inner cover body has a groove and the upper and lower guide parts are wider than the left and right guide parts, making it easier to insert the protrusion. Furthermore, the protrusion can be fixed by having an inclined part on the front side and a storage part beyond the inclined part. This makes it possible to stably remove the inner cover lid part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The lighting fixture with a blower of the present invention will be described with reference to the drawings. Note that the following description is of one embodiment, and the present invention is not limited thereto. The description will be made with reference to Figure 1, with "upper" and "lower" as the basis.

[0016] The lighting fixture with a blower 1 is made of a resin material such as plastic as shown in Figures 1 and 2, and has a mounting body 2 to be attached to a wall surface, a circular lighting section 3 that is open on the inside at the outer periphery, an outer cover section 4 that stands upward from the inner edge of the lighting section 3, and an inner cover section 5 equipped with a propeller-shaped blower 7 and a retaining ring body 8 that exist in the storage space inside the lighting section 3 and the outer cover section 4, and the inner cover section 5 can be tilted while containing the blower 7 by the rotating shaft 52 and the inner cover rotating section 6 that exist between the outer cover section 4 and the inner cover section 5. Electrical wiring (not shown) is arranged from the mounting body 2 through the outer cover section 4 and the inner cover section 5 to the blower 7.

[0017] As shown in Figure 2, the mounting body 2 includes a ceiling mounting portion 21 that is long in the vertical direction and is attached to the ceiling, an outer cover fixing base 22 that fixes the outer cover portion 4 described later, and screws 25 that connect the ceiling mounting portion 21 and the outer cover fixing base 22.

[0018] The ceiling mounting part 21 has a mounting body 21b having a mounting body protruding part with a metal base 21a at the top that is attached to a socket (not shown) on a wall surface such as a ceiling by screwing, and a cylindrical part that widens from the top to the bottom. The mounting body 21b has a rotation engagement part 21c that engages with a rotationally engaged part 22a located above the outer cover fixing base 22 described later. The rotation engagement part 21c is made rotatable in the left and right directions (up and down are the axial direction) by a disk member 21d, and communicates with electrical wiring (not shown) inside. Note that the ceiling mounting part 21 is not limited to one that is screwed into the socket by the base 21a, but may be one that has a claw part and is attached to the ceiling.

[0019] The rotation engagement part 21c is formed with an attachment groove in which convex and concave grooves are alternately formed on the circumference, and engages with a rotationally engaged part 22a of the outer cover fixing base 22 having the same shape as the opposing part, and is rotatably supported by a screw 25. This allows the outer cover part 4 to rotate up and down in stages by the convex and concave. By loosening the screw 25 and changing the engagement position of the convex and concave, the entire lighting fixture with blower 1 arranged vertically to the ceiling can be tilted.

[0020] The outer cover fixing base 22 is fixed to the upper part of the outer cover part 4 described later, and connects the mounting body 2 to the outer cover part 4. As described above, the outer cover fixing base 22 has a rotatable engaged part 22a that protrudes upward from the cylindrical member, and rotatably engages with the rotatable engaging part 21c of the mounting body 2. The outer cover fixing base 22 is fixed to the outer cover part 4 via a connecting metal fitting 23.

[0021] Next, the lighting unit 3 and the outer cover unit 4 will be described as shown in Fig. 3 in addition to Figs. 1 and 2. The lighting unit 3 is a so-called doughnut-shaped annular member having a predetermined vertical height and space inside, and the blower 7 is positioned in the storage space S, which is the internal space, within the mesh member of the inner cover unit 5. The lighting unit 3 itself is a transparent lighting cover, and is joined to a lighting base 41 that extends from the lower end of the outer cover unit 4 in a flange-like shape. The lighting base 41 is provided with a light-emitting unit 31 formed by arranging light-emitting diodes in a circular ring shape, and emits light. The storage space S is the space from the lower surface of the lighting unit 3 to the inside of the outer cover unit 4.

[0022] Specifically, the lighting base 41 of the outer cover part 4 is a groove-shaped member whose circumference faces downward and whose bottom surface is open, and is made up of an inner peripheral wall 41a standing on the inner peripheral side, an outer peripheral wall 41b standing on the outer peripheral side, and an upper wall 41c connecting the inner peripheral wall 41a and the outer peripheral wall 41b. The light-emitting part 31 is disposed along the outer peripheral side of the inner peripheral wall 41a, and the lighting part 3 is attached so as to follow the outer peripheral side of the outer peripheral wall 41b.

[0023] The illumination unit 3 is a transparent member having an approximately U-shaped cross section, and includes an inner peripheral wall 3a, an outer peripheral wall 3b, and a lower wall 3c connecting the lower ends of the inner peripheral wall 3a and the outer peripheral wall 3b. As described above, the inner peripheral wall 3a is attached along the inner peripheral wall 41a of the illumination base 41, and the outer peripheral wall 3b is attached along the outer peripheral wall 41b of the illumination base 41.

[0024] The light emitting section 31 is a light emitting portion provided with LED elements 32, 32 attached to a substantially annular member, and the LED elements 32 are bonded so as to be continuously spaced equally in two rows, one above the other. The LED elements 32 may be attached to the substantially annular member in two rows as shown in FIG. 1, or may be attached to the substantially annular member in only one row.

[0025] The outer cover part 4 is a mesh-like cover body that protrudes upward from a position near the inner peripheral wall 41a of the lighting base 41. Specifically, the outer cover part 4 is formed in a mesh-like shape by a plurality of bent legs 42, 42 that rise upward from the position of the inner peripheral wall 41a of the lighting base 41 and are bent at approximately right angles, and are spaced apart so that the user's fingers cannot be inserted. A fixing part for fixing the outer cover fixing base 22 is provided at the upper center position. These bent legs 42, 42 are in the above-mentioned positional relationship, so that a mesh-like member is formed so as to rise upward from the inner peripheral position of the lighting unit 3. The rising height of the bent legs 42 is about 1.5 to 2 times the height of the inner cover main body 51, and a storage space S for storing the inner cover part 5 is formed inside. Since the height is 1.5 to 2 times the height of the inner cover part 5, the storage space S in which the inner cover part 5 is stored and tilted is secured as described later (see FIG. 4).

[0026] The multiple bent upright portions 42, 42 are arranged circumferentially, and include a rotating shaft holding portion 43 having an inverted U-shaped groove for holding the rotating shaft 52 protruding outward from the inner cover main body 51 from above, and an open portion 44 below the rotating shaft holding portion 43, at a circumferential position 1 that is the upper edge position of the inner circumferential wall 41a, and at a circumferentially opposite position from the position. The rotating shaft holding portion 43 includes a lower rotating shaft holding portion 61 having a U-shaped groove and a bearing 62 made of resin, which support the rotating shaft 52 from below. The rotating shaft 52 is passed through the bearing 62 and sandwiched between the rotating shaft holding portion 43 and the lower rotating shaft holding portion 61, so that the inner cover main body 51 rotates and tilts as described below (see FIG. 4).

[0027] In addition, a part of the outer cover part 4 is provided with an outer cover guide part 45 to which electrical wiring communicates by forming a wall surface one step lower than the bent upright part 42. Electrical wiring (not shown) is passed around the outer periphery of the outer cover part and covered with a blind cover 46.

[0028] The privacy cover 46 is a portion bent at a substantially right angle and made up of a horizontal portion and a vertical portion, and is disposed on a wall portion on a side surface of the outer cover part 4. The privacy cover 46 has a claw portion that protrudes downward on the horizontal portion and a claw portion that protrudes downward on the vertical portion, and is disposed in engagement with the outer cover part 4.

[0029] Next, the inner cover part 5 will be described with reference to FIG. 4 in addition to FIG. 1 and FIG. 2. The inner cover part 5 is an annular cylindrical member having a diameter smaller than the inner peripheral wall 41a of the outer cover part 4. The inner cover main body 51, which is slightly tapered upward, is engaged with the lower inner cover lid part 53 to form an integrated cover, and the blower 7 is rotatably provided inside. The inner cover main body 51 has a circumferential surface, and a plurality of rods 51b, 51b are formed in a mesh shape from the upper frame circle 51a to the lower frame circle 51c on the side surface, which is the circumferential surface, so that the user's fingers cannot be inserted. Similarly, the lower inner cover lid part 53 is formed in a mesh shape with a plurality of rods 53b, 53b from the outer peripheral edge 53a to the inside, thereby preventing the user from coming into contact with the blower 7 during operation and being injured.

[0030] The cylindrical inner cover body 51 has an inner cover lid part 53 removably disposed on its lower surface, and an open space 54 on its upper surface. Specifically, the upper surface of the inner cover body 51 is provided with a substantially cross-shaped holder 55 for holding the mesh-like upper frame circle 51a, and the area other than the holder 55 is the open space 54. This open space differs from the mesh-like members of the outer cover part 4 and the inner cover part 5 in that it has an open area large enough that a person's finger or a cleaning tool can easily pass through. Providing the open space 54 in the holder 55 makes it possible to insert a cleaning tool between the holders and clean the back surface of the outer cover part 4, which will be described later (see FIG. 5).

[0031] Further, at position 1 on the circumferential side surface of the inner cover main body 51 and at a position opposite to position 1, rotating shafts 52, 52 protruding outward are disposed. As described above, the rotating shafts 52, 52 are rotatably held, so that the inner cover part 5 rotates and can be tilted together with the internal blower 7. The rotating shaft 52 is a cylindrical shaft having a plurality of uneven shapes on its circumference (see FIG. 6). These unevennesses are made of soft resin, and when the rotating shaft is sandwiched between the rotating shaft holding part 43 and the lower rotating shaft holding part 61 inside the bearing 62 and rotates, a catch occurs, enabling stepwise tilting by a simple method.

[0032] Further, the holder 55 has a substantially circular blower attachment portion 55a near the center for attaching the blower 7. The blower 7 is rotatably supported by an internal motor while being attached by the blower attachment portion 55a.

[0033] Next, a description will be given of the joining of the inner cover lid part 53 and the inner cover main body 51. The inner cover main body 51 has an inner cover groove part 56 formed in the lower frame circle 51c, which engages with a locking protrusion part 53c protruding inward from the outer peripheral edge 53a of the inner cover lid part 53 to be detachably connected. Four locking protrusion parts 53c are arranged at equal intervals on the inner cover lid part 53, and the inner cover groove parts 56 are arranged at corresponding positions.

[0034] To explain the inner cover groove 56 in detail, as shown in Fig. 7, the groove is a groove-shaped portion facing the circumferential direction, and includes a vertical guide portion 56a that guides the locking protrusion 53c in the vertical direction, and a horizontal guide portion 56b that is narrower than the vertical guide portion 56a and guides an inward protrusion (not shown) described later in the horizontal direction. The vertical guide portion 56a is a substantially square-shaped portion formed in the vertical direction of the inner cover groove 56 in Fig. 3, and is formed wider than the horizontal guide portion 56b so as to make it easier to insert and remove the locking protrusion 53c. The horizontal guide portion 56b is a substantially rectangular groove that is long in the horizontal direction, and includes a straight portion 56c in the horizontal direction of the inner cover main body 51, an inclined portion 56d that inclines upward from the end of the vertical guide portion 56a, and a storage portion 56e in the shape of a circular recess that descends on a curve from the apex of the inclined portion 56d and then rises in an arc toward the straight portion 56c again. The left and right guide portions 56b allow the locking protrusion 53c to move smoothly to the storage portion 56e after it has moved along the upper and lower guide portions 56a. Also, the locking protrusion 53c can be fixed by surrounding the apex of the inclined portion 56d with the inner wall of the storage portion 56e.

[0035] 8, when the inner cover part 5 is manually tilted by the rotating shaft 52, the upper end and upper edge of the inner cover part 5 are positioned higher than the lower end and lower edge of the outer cover part 4. At this time, the storage space S is formed so that the part where the inner cover part 5 is tilted by the rotating shaft 52 and positioned upward abuts against the inner surface of the outer cover part 4. By making the rising height of the outer cover part 4 about 1.5 to 2 times that of the inner cover part 4 in this way, the upper surface part of the inner cover part 5 where the open space 54 is formed is not exposed from the side or lower part of the outer cover part 4, and the upper part of the inner cover part 5 is opened for easy cleaning, while preventing the inner cover part 5 from accidentally rotating 360° and causing injury to the user by touching the blade part 73 of the blower 7.

[0036] As shown in Figs. 1 and 2, the blower 7 is rotated by an internal drive unit (not shown), and is covered at the top by the outer cover unit 4 and at the bottom by the inner cover lid unit 53. The upper end of the cylindrical rotating tube part that serves as the rotation axis is joined to the inner cover unit 5 at a circular joint, and five arc-shaped blade parts are attached in a spiral shape at equal intervals to the wall surface, and the blade parts are rotated by the drive unit. Each blade part has a notch at the end of the side with the short radius. The notch prevents the blade parts from coming into contact with the blind cover 46 when rotating and causing damage. The damaged blade parts are prevented from hitting the user directly and causing injury. Although the number of blade parts is described as five, it is not limited to five.

[0037] A method of attaching the blower 7 and the inner cover part 5 to the outer cover part 4 will be described. First, the blower 7 is attached by fixing it to the blower attachment part 55a of the inner cover main body 51 with a screw. Next, the inner cover groove part 56 of the inner cover main body 51 and the inner cover lid part 53 are connected. Specifically, the procedure is as follows. The locking protrusion 53c of the inner cover lid part 53 passes through the upper and lower guide parts 56a of the inner cover groove part 56 of the inner cover main body 51 and abuts against the straight part 56c of the left and right guide parts 56b. Then, the locking protrusion 53c is stored in the storage part 56e of the inner cover groove part 56, completing the engagement between the inner cover main body 51 and the inner cover lid part 53, and the blower 7 is protected by the inner cover lid part 53.

[0038] Next, the inner cover main body 51 and the inner cover rotating part 6 are engaged. Specifically, the bearing 62 is attached to the rotating shaft 52, which is then sandwiched between the rotating shaft holding part 43 and the lower rotating shaft holding part 61 and fixed with a screw to complete the rotatable (tiltable) engagement. This completes the attachment of the blower 7 and the inner cover part 5 to the outer cover part 4.

[0039] Next, a method of assembling the lighting unit 3 will be described. The light-emitting unit 31 is attached so as to go around the inner peripheral wall 41a of the lighting base 41 of the outer cover unit 4, and is engaged with the inner peripheral wall 3a of the lighting unit 3, thereby completing the assembly of the lighting unit 3. Next, a method of assembling the outer cover fixing base 22, the outer cover unit 4, and the mounting body 2 will be described. The outer cover fixing base 22 is connected to the outer cover unit 4 via the connecting fittings 23, and is connected to the mounting body 2 which can rotate left and right and up and down as described above. Then, the base 21a of the mounting unit is joined to a socket on the ceiling to enable installation. [Explanation of symbols]
