FAN APPARATUS WITH LIGHT SPECIFICATION

Problems to be Solved by the Utility Model

[001] However, the rotary shaft for the fan blades in this blower is fastened in a single

direction (vertical), so efficiency was poor in the aspect of air circulation.

[002] The present utility model takes the aforementioned circumstances into

consideration. An objective of the present utility model is to provide a blowing apparatus with

illumination functionality that is capable of further improving indoor air circulation.

Means for Solving the Problem

[003] To solve the aforementioned problem, the blowing apparatus with illumination

functionality that relates to the present utility model comprises a base part installed on a ceiling

surface;

a blower that is disposed on the bottom side of the base part;

a blower supporting part that supports the blower;

an illuminating part that is positioned in a ring-like manner around the outer periphery of the

blower;

an illumination linking part that links the illuminating part and the base part;, and

a tilting mechanism that tilts the blower relative to the ceiling surface.

[004] In the constitution described above, the illuminating part is positioned in a ring-like

manner around the outer periphery (circumference) of the blower. In other words, this constitution

has both blowing functionality and illuminating part functionality. The blower has a tilting

mechanism that tilts the blower relative to a ceiling surface. Therefore, the blowing direction of

the blower can be changed by utilizing the tilting function. For that reason, it is possible

appropriately to adjust the blowing direction while considering the indoor conditions, whereby it

is possible further to improve indoor air circulation.

[005] It is preferable for the base parts that relate to the present utility model to be

equipped with a first base part positioned on the ceiling surface side and a second base part that is

integrated at the bottom side of the first base part, and for the second base part and the blower

supporting part to be linked together via the tilting mechanism.

[0061 By using this constitution, it is possible to change the blowing direction by linking

the blower supporting part relative to the second base part that comprises the base parts.

[007] It is preferable for the present utility model to be equipped with a rotation

mechanism that rotates the second base part relative to the first base part around a vertical shaft.

[008] By using this constitution, it is possible to rotate the blower itself in a state where

the blowing direction of the blower is inclined. For that reason, it is possible to further perform

uniform indoor ventilation.

[009] It is preferable for the tilting mechanism described for this present utility model to

include a mechanism that rotatably supports the blower supporting part on the shaft that is set in

the horizontal direction.

[010] With this constitution, it is possible to tilt the blower by rotating the blower

supporting part around the horizontal shaft.

[011] It is preferable for the second base part described for this present utility model to

have an integrated rotary motor that is composed of a tilting drive motor, which comprises the

tilting mechanism, and the rotation mechanism.

[012] With this constitution, it is possible to attain a constitution that rotates the blower

in a state where the blower is tilted.

[013] It is preferable for the blower described for this present utility model to be equipped

with a cylindrical case that is disposed around the periphery of the blower blades, wherein a ring

shaped gap is formed between this cylindrical case and the illuminating part.

[014] With this constitution, it is possible to drive and tilt the blower without interfering

with the illuminating part because a predetermined gap is formed between the blower and the

illuminating part.

[015] It is preferable for the rotation mechanism described for this present utility model

to be equipped with a large-diameter gear, which is fastened on the first base part, and a small

diameter gear, which is driven by the rotary motor and circles around the periphery of the large

diameter gear.

[016] With this constitution, it is possible to rotate the second base part relative to the first

base part by rotating the small-diameter gear using the rotary motor. In other words, it is possible

to rotate the blower itself.

Mode for Carrying Out the Device

[027] A preferred embodiment of the blowing apparatus (ceiling circulator) with

illumination functionality that relates to the present utility model will now be described with

reference to the drawings. Fig. 1 is an external, perspective of the blower apparatus according to

this embodiment as seen from the front. Fig. 2 is an external, perspective view of the blower

apparatus depicted in Fig. 1 from a rear side. Fig. 3 is a side view. Fig.4 is a front view. To facilitate a description , the ceiling surface side is defined as the rear side (top), and the base surface side is defined as the front side (bottom).

[028] The blower apparatus according to the present utility model has both illumination

functionality and blowing functionality. The blowing apparatus is mounted to on an indoor ceiling

surface for use. The blowing apparatus is equipped with a base part 1 that is mounted to a ceiling

surface, a blower 2 (fan) that is disposed on the bottom side of the base part 1, a blower supporting

part 3 that supports the blower 2, an illuminating part 4 that is positioned in a ring-like manner

around the outer periphery of the blower 2, and illumination linking parts 5 that link the

illuminating part 4 and the base part 1. The materials that constitute the base part 1 may be

appropriately selected from metal, or resin, or the like.

[029] As illustrated in Fig.3, the base part 1 is equipped with a first base part 10 positioned

on the ceiling surface side, and a second base part 11 that is integrated at the bottom side of the

first base part 10. The first base part 10 is fastened on the ceiling surface using known means. The

first base part 10 has a cylindrical case, and a material such as a power supply circuit, and a control

circuit and the like are disposed on an inside.

[030] The first base part 10 has a large-diameter part 10a and a small-diameter part 10b;

both are formed into a cylindrical shape. A recess 10c is formed in the front side of the small

diameter part lOb, and the second base part 11 is disposed in this recess 1Oc. The second base part

11 has a cylindrical case with a smaller diameter than the small-diameter part IOb of the first base

part 10. The details are described below. The second base part 11 is rotatably installed on the small

diameter part lb of the first base part 10. The rotary shaft is set in a manner so that it is oriented

vertically, and it is configured in a manner so that the blower 2 and the blower supporting part 3

can integrally rotate when the second base part 11 rotates.

[031] As illustrated in Fig.4, the blower 2 is composed of 7 fan blades 20. There are no

particular restrictions with respect to the shape or number of the fan blades 20. It is preferable for

the rotation direction of the fan blades 20 to be able to be set to rotate in both the clockwise and

A counter-clockwise directions. However, it is also acceptable to limit the rotation direction to only one of these directions.

[032] A cylindrical case 21 is disposed around the periphery of the fan blades 20; it is

linked to an impeller guard 22 positioned at a center of the fan blades 20, via three spokes 23. The

cylindrical case 21 is formed in a ring-like shape when viewed from the front, and has an inner

diameter that is slightly larger than an outermost diameter of the fan blades 20.

[033] The illuminating part 4 is covered by a translucent cover 40. The cover 40 is formed

in a ring-like shape when viewed from the front. Fig. 5 is a front side view showing a state in which

the cover 40 has been removed. Fig. 6 is a sectional view of A-A in Fig. 5. Fig.7 is a sectional view

of B-B in Fig. 5. The cover 40 is disposed above an illumination substrate 45 (floor surface side)

so that it can be freely attached and detached. A known locking member 41 for locking the cover

40 on top of the illumination substrate 45 is disposed at three locations along the circumferential

direction. Preferably, the illumination substrate 45 is metal and it is equipped with a heat radiation

functionality.

[034] The top of the illumination substrate 45 is equipped with LED substrate 42 equipped

with many integrated LEDs 43. The tops of the LED substrates 42 are equipped with a diffusion

cover 44 that covers the LEDs 43. The diffusion covers 44 are translucent and attain uniform

illumination by diffusing light that is illuminated from the LEDs 43. The diffusion covers 44 have

functionality that protects the LED substrates 42 from being touched by a user's hands or the like.

[035] Fig. 5 illustrates a state in which the diffusion covers 44 are removed. The LED

substrates 42 have a 'V' shape, and four are arranged along a circumferential direction. Four

diffusion covers 44 are also arranged in the same manner. It is acceptable for the LED substrates

42 to be arch-shaped, but there are no particular restrictions with respect to the shape. It is also

possible appropriately to set the number arranged for the diffusion covers 44 and the shape of the

LED substrates 42. When disposing a plurality of LED substrates 42, the adjacent metal sheets are

electrically-connected via wiring.

[036] A ring-like gap is formed between the inner circumference of the cover 40 of the

illuminating part 4 and the outer circumference of the cylindrical case 21 for the blower 2 (see Fig.

5). As described below, the blower 2 has tilting functionality, but a necessary gap must be ensure

to allow for the tilting functionality to be easily driven.

[037] As can be understood from Fig. 3, the tips of the fan blades 20 will still slightly

project more to the front side than the cover 40 for the illuminating part 4 even if the blower 2 is

not tilted. The rear parts of the fan blades 20 will not project from the illuminating part 4 while the

blower 2 is not tilted.

[038] The illumination linking parts 5 link the illumination substrate 45 of the

illuminating part 4, the first base part 10, and the large-diameter part 1Oa together. The three

illumination linking parts 5 have an empty space inside of them, and one of these illumination

linking parts 5 is used to feed wire. For that reason, it is possible to supply power to the illuminating

part 4.

[039] As can be understood from Fig. 6, the blower 2 is supported by a blower supporting

part 3 that is positioned behind the blower 2. The blower supporting part 3 has a case 32, which

houses a blade motor 30 and a motor shaft 31 therein. The fan blades 20 are installed on the motor

shaft 31 so that the fan blades 20 can be rotationally-driven. The fan blades 20 are screwed into

the motor shaft 31 via a cap 33 that has a screw.

[040] The cylindrical case 21 is constituted by a first case part 21a on a front side and a

second case part 21b on the rear side being joined. The first case part 21a is joined to the second

case part 21b so that they can be freely attached and detached, whereby making it possible to

remove the first case part 21a. For that reason, it is possible to remove the fan blades 20 for

cleaning, or the like. The first case part 21a is integrated with the spokes 23, whereby the first case

part 21a can be integrally removed with the spokes 23.

[041] The second case part 21b is linked with the blower supporting part 3 via three

spokes 24 (see Fig. 6). The material for the member for constituting the cylindrical case 21 may be

appropriately selected such as from metal, or resin, or the like.

[042] The rear side surface 32a of the case 32 is formed into a spherical surface (or

spherical shape). This allows for an empty space to be ensured to prevent interference with the

second base part 11 when the blower 2 and the blower supporting part 3 are integrally tilted and

driven.

[043] Next, the tilting mechanism that t tilts the blower 2 relative to the ceiling surface

will be described. This tilting mechanism can appropriately adjust the blowing direction of the

blower 2 in consideration of the indoor conditions, whereby it is possible further to improve the

indoor air circulation.

[044] Fig. 8 is a sectional view that illustrates a state in which the blower 2 is tilted. Fig.

9 is a side view of a state in which the illuminating part 4 has been removed. For that reason, it is

possible to change the blowing direction of the blower 2. The blowing direction can be operated

using a remote control (not illustrated). The tilting angle in the examples depicted in Fig. 8 and

Fig. 9 is 120 relative to a level surface. It is also acceptable to allow the tilting angle to be changed

in steps or not in steps.

[045] As illustrated in Fig.7 and Fig.9, the blower supporting part 3 can be rotated around

the horizontal axis X relative to the second base part 11. For that reason, it is possible to tilt and

drive the blower supporting part 3 relative to the second base part 11. A pair of bearings 34 have

been disposed to provide support so that rotation can be performed (see Fig.7). A gear 35 is

disposed to one of these bearings 34, which is driven by a gear and a tilting drive motor (not

illustrated) disposed at the second base part 11. A rotary shaft for the gear 35 is oriented in the

horizontal direction. The range in which the gear 35 can be rotated is, for example, set to 181 or

less, whereby the tilting angle will be restricted. For example, by disposing an appropriate

mechanical stopper and/or a sensor that detects the rotation angle, it is possible to control the tilting

range and the tilting angle.

[0461 Next, the rotation mechanism that rotates the second base part 11 around the vertical

shaft relative to the first base part 10 will be described. As previously described, a tilting

'7 mechanism is disposed, but it rotate the blower 2 in a tilted state. This makes it possible evenly to blow indoors.

[047] Fig. 10 is a sectional view of C-C in Fig. 3. The rotation mechanism is composed

of a large-diameter gear 60 that is fastened to the first base part 10 side and a small-diameter gear

61 that is disposed on the second base part 11 side. The small-diameter gear 61 is rotated and driven

by a rotary motor (not illustrated). This rotary motor is mounted on the second base part 11. When

the small-diameter gear 61 is driven, the small-diameter gear 61 moves to revolve around the large

diameter gear 60 because the large-diameter gear 60 is fastened. For that reason, the second base

part 11 is rotated and driven relative to the first base part 10, and the blower 2 and the blower

supporting part 3 that are disposed at the second base part 11 are rotated and driven together.

[0481 A central shaft 62 for rotational driving is disposed in the vertical direction. Power

is supplied from the power source part, which is disposed on the first base part 10 to the second

base part 11 via the central shaft 62. A known slip ring mechanism (not illustrated) is also disposed

smoothly to supply power via the rotating part(s). The power that is supplied to the second base

part 11 is supplied to the blower 2 and the illuminating part 4, and supplied to the tilting drive

motor and the rotary motor.

Alternative Embodiment

[049] Although the first base part 10 in this embodiment is composed of two cylindrical

parts, namely a large-diameter part 10a and a small-diameter part 10b, there are no limitations to

the shape of the first base part 10. For example, it is also acceptable to constitute the first base part

10 using a backward-facing frustum shape. The shape of the second base part 11 is also not limited

only to a cylindrical shape. It is also acceptable to constitute the second base part 11 using other

shapes such as a frustum shape, or the like.
