The end of the power cord cover 24 on the central side of the main body 22 is inserted between the main body support member 21 and the upper surface of the main body 22. In this state, the height position of the flange portion 21c of the main body support member 21 is the height position of the locking portion 31a1 of the upper plate portion 31a of the support member fitting portion 31. This prevents the main body support member 21 from being pulled out and removed from the support member fitting portion 31.

(constitution of the body portion 22)

Fig. 9(a) is a vertical cross-sectional view showing the structure inside the main body 22 when viewed from the direction shown in fig. 2 (a), and fig. 9 (b) is a vertical cross-sectional view showing the structure inside the main body 22 when viewed from the direction shown in fig. 2 (b). Fig. 10 (a) is a perspective view of the structure shown in fig. 9(a) as viewed from obliquely above, and fig. 10 (b) is a perspective view of the structure shown in fig. 9 (b) as viewed from obliquely below. Fig. 11 is a plan view showing a state where the upper case portion 41 of the main body portion 22 is removed.

As shown in fig. 9(a) and (b), fig. 10 (a) and (b), and fig. 11, the main body 22 includes an upper casing 41, a blower 42, a blower passage 43, a HEPA Filter (High Efficiency Particulate Air Filter)44, an illumination unit 45, an ion generating element 46 (see fig. 11), a pre-Filter 49, a lower cover member 52, and a flap ring 58.

The upper tank 41 is positioned at the uppermost portion of the main body 22 and covers the inside of the main body 22 from above. The upper casing portion 41 has a shape in which the peripheral edge portion is bent downward and inclined. The support member fitting portion 31 is attached to the upper case portion 41.

The blower 42 is disposed at a position directly below the support member fitting portion 31, that is, the ceiling junction box 12, and includes a fan 47 and a motor 48 for rotating the fan 47. The fan 47 and the motor 48 are provided at the center of the main body 22 in the radial direction (direction parallel to the ceiling) so that the centers of the fan 47 and the motor 48 substantially coincide with the center of gravity of the main body 22 in the vertical direction.

The motor 48 is disposed above the HEPA filter 44, and the rotary shaft 48a protrudes upward from the body portion of the motor 48. The fan 47 is a sirocco fan (sirocco fan) and is attached to the rotating shaft 48a of the motor 48 so as to cover the upper portion of the motor 48 and the periphery of the motor 48.

As shown in fig. 11, the fan 47 is provided inside the air blowing passage 43. The air flow path 43 includes two air outlets 43a in opposite directions, and the air is blown out from the air outlets 43a by the rotation of the fan 47. The air outlet 43a is provided with a swing blade 57 extending in the vertical direction.

The ion generating elements 46 are respectively provided in the vicinity of the two air outlets 43a of the air flow path 43, generate ions, and add the generated ions to the air blown out from the air outlets 43a.

The HEPA filter 44 functions as a dust collection filter and is attached to the upper surface of the HEPA filter holding member 50 provided at the lower portion of the main body 22. The HEPA filter holding member 50 has, for example, a thin-plate container shape, and is detachable from the main body 22. The operation of the HEPA filter holding member 50 when the HEPA filter holding member 50 is fitted to the main body 22 (when fixed) may be performed by pressing the HEPA filter holding member 50 against the main body 22 or rotating the HEPA filter holding member 50 with respect to the main body 22. Therefore, in the blower 1, by removing the HEPA filter holding member 50 from the main body 22, the HEPA filter 44 can be removed from the main body 22 at the same time.

A filter suction port 50a (see fig. 10 b) having a lattice-like opening, for example, is formed in the lower surface of the HEPA filter holding member 50, and a pre-filter 49 and a pre-filter holding member 51 are provided below the HEPA filter holding member 50. The pre-filter 49 removes dust and foreign matter before the HEPA filter 44.

The pre-filter holding member 51 holds the pre-filter 49. The prefilter holding member 51 includes downward projecting portions 51a projecting downward on both side portions. The lower protruding portion 51a abuts on the upper surface of the lower cover 52 in the closed state of the lower cover 52. Thus, in the closed state of the lower cover member 52, the pre-filter holding member 51, that is, the pre-filter 49 is not easily detached, and the lower cover member 52 can be reinforced against the load from the lower surface side of the lower cover member 52. The pre-filter 49 and the HEPA filter 44 are provided in an air supply path to the fan 47.

A lower cover member 52 is provided below the HEPA filter holding member 50 (pre-filter holding member 51), and a space is formed between the HEPA filter holding member 50 (pre-filter holding member 51) and the lower cover member 52. An inlet 60 to the main body 22 is formed above the lower cover member 52 around the lower cover member 52.

The lower cover member 52 has one end fixed to the main body 22 (specifically, the HEPA filter holding member 50) by a magnet 53 and the other end fixed to the main body 54 by a V-spring 54. The magnet 53 and the V-spring 54 are attached to the upper surface side of the lower cover member 52. Therefore, the lower cover member 52 can be opened in a state of being connected to the main body 22 by the V-spring 54 by separating the side fixed by the magnet 53 from the main body 22. The lower cover member 52 is detachable from the main body 22 by detaching the side fixed by the magnet 53 and the side fixed by the V-spring 54 from the main body 22. In this case, the V-shaped spring 54 can be easily detached from the main body 22 by a user operating the spring from the state expanded into the V-shape to the closed state as in the conventional art.

The illumination unit 45 includes an illumination substrate 55 and an illumination cover 56 covering the illumination substrate 55. The illumination substrate 55 is provided with a plurality of LEDs and has a hollow circular plate shape. The illumination cover 56 is formed of a light transmitting member, such as a translucent resin material, and includes a cover lower portion 56a and a cover upper portion 56b. The cover lower portion 56a is a state in which an annular side wall portion is bent to protrude obliquely downward. The cover upper portion 56b is in a state where the annular side wall portion is inclined inward of the illumination cover 56 with respect to the vertical direction. Accordingly, a part of the light emitted from the LEDs of the illumination substrate 55 toward the cover lower portion 56a is reflected by the inner surface of the cover lower portion 56a, and further passes through the cover upper portion 56b and a flap ring 58 described later to be emitted to the ceiling around the blower 1.

(construction of the swing blade ring 58)

Fig. 12 is a perspective view showing the structure of the swing blade ring 58 shown in fig. 9(a) and (b). The flap ring 58 is formed in an annular shape and is provided between the outer peripheral portion of the upper case portion 41 and the outer peripheral portion of the illumination cover 56 of the illumination portion 45. The flap ring 58 includes an opening 58a that can face the air outlet 43a of the air flow path 43, and is rotatable by manual operation with respect to the upper case portion 41 and the illumination cover 56. In the present embodiment, the openings 58a are formed at two positions separated by 180 ° in accordance with the number of the blowing ports 43a of the air blowing path 43. The opening 58a is opened from the lower end of the swing ring 58 and has a height H.

The opening height of the opening 58a determines the blowing direction (blowing angle) of the wind, and the lower the height of the opening 58a, the lower the blowing angle of the wind. In the present embodiment, the opening height H1 of the opening 58a is set so as to blow air at an angle of 45 ° obliquely downward with respect to the horizontal direction. This blow-off angle is an angle in which the ions generated by the ion generating element 46 are distributed over the entire room with good efficiency.

The number of the air outlets 43a of the air blowing passage 43 is not limited to two, and when the number of the air outlets 43a is changed, the number of the openings 58a is also changed in accordance with the number of the air outlets 43a.

(operation state informing device 81)

Fig. 13 (a) is an explanatory diagram illustrating a state display operation of the operation state notification device 81 of the blower device 1, and fig. 13 (b) is an explanatory diagram illustrating a configuration of the operation state notification device 81. Fig. 14 is a block diagram showing a configuration of a drive control unit of the operation state notification device 81.

As shown in fig. 13 (a), the blower device 1 includes an operation state notification device 81. The operation state notification device 81 displays some images on the ceiling to notify the user that the blower 1 is in operation and that the detection result of the odor sensor 91 (see fig. 14) is being obtained. Fig. 13 (a) shows a state display 85 performed on the ceiling by the operation state notification device 81.

As shown in fig. 13 (b), the operation state notification device 81 includes, for example, a substrate 82, an LED83 provided on the substrate 82, and a lens 84. The lens 84 diffuses the light emitted by the LED 83.

As shown in fig. 14, the operation state notification device 81 includes a drive control unit for displaying a state 85 by the LED 83. The drive control section includes an odor sensor 91, a control section 92, an LED drive section 93, and an LED 83. The odor sensor 91 is provided, for example, inside the body portion 22 (see fig. 17).

The odor sensor 91 detects an odor, that is, contamination of the air entering the body portion 22. The LED83 is configured to include, for example, a color filter, and is configured by a plurality of LEDs that display light blue (sky blue), yellow, orange, and red colors. Light blue is used to indicate air cleanliness, and red is used to indicate air pollution, and the state of air pollution proceeding is indicated from light blue to yellow, orange, and red. The control unit 92 controls the driving of the LED driving unit 93, that is, the LED83, and lights the LEDs of any of the respective colors in accordance with the detection result of the odor sensor 91. Alternatively, the control unit 92 lights up LEDs of all colors, and lights up LEDs of a color suitable for the air pollution state more than LEDs of other colors according to the detection result of the odor sensor 91.

The upper box portion 41 is provided with a light transmission window 86 through which light emitted from the LED83 is transmitted to display a status 85 on the ceiling 11. Since the light transmission window 86 has an elongated shape, the state display 85 has an elongated shape.

The operation state notification device 81 may also display that the ion generating element is in operation by the state display 85.

(example of specifications of blower 1, etc.)

Here, an example of the weight and size of the blower 1 and the ceiling junction box 12 is shown. The air blowing device 1 weighed 7.5kg (body support member 21: 1.5kg, body portion 22: 6kg), had a diameter of 600mm and a height of 200 mm. The ceiling junction box 12 is compliant with the standard of JIS C8310.

(installation of air blowing device 1 to ceiling)

In the above configuration, a method of attaching the air blowing device 1 to the ceiling will be described.

First, the body support member 21 is attached to the ceiling junction box 12 provided in the ceiling 11 (ceiling) 11. The main body support member 21 is fixed to the ceiling junction box 12 by screws 23.

Next, the main body 22 is attached to the main body support member 21. In this case, the main body 22 is lifted up to the position of the ceiling 11, moved toward the main body support member 21 in parallel with the lower surface of the ceiling 11 (see fig. 5), and the support member fitting portion 31 of the main body 22 is fitted to the main body support member 21 (see fig. 6). In the fitted state, the flange portion 21c of the main body support member 21 is positioned between the opposing upright portions 31b of the support member fitting portion 31, and the upper plate portion 31a of the support member fitting portion 31 is positioned above the flange portion 21c of the main body support member 21. Thereby, the main body 22 is supported by the main body support member 21.

Next, the main body 22 is rotated so that the fitting protrusion 31a2 of the upper plate portion 31a of the support member fitting portion 31 fits into the fitting hole 21c1 of the flange portion 21c of the main body support member 21. Thereby, the main body 22 is fixed so as not to rotate.

Next, the power cord 25 connected to the ceiling junction box 12 and drawn out from below the main body support member 21 toward the upper surface portion of the main body 22 is connected to the power supply connection portion 32 of the main body 22 (see fig. 7).

Next, the power cord cover 24 is attached to the main body 22 so as to cover the power cord 25 (see fig. 8). In this case, the power cord cover 24 is configured such that the end portion of the main body 22 on the central portion side is inserted between the main body support member 21 and the upper surface portion of the main body 22. In this state, the height position of the flange portion 21c of the main body support member 21 is the height position of the locking portion 31a1 of the upper plate portion 31a of the support member fitting portion 31 of the main body 22. This prevents the main body support member 21 from being pulled out and removed from the support member fitting portion 31.

The detachment from the main body 22 of the main body support member 21 can be performed in the reverse order of the above-described attachment to the main body 22 of the main body support member 21.

(rotation of the swing blade ring 58)

As shown in fig. 11, the main body 22 includes an annular space region 59 along the inner surface of the vane ring 58. In this space region 59, corpses and dust of insects entering through the opening 58a are accumulated.

Therefore, the swinging blade ring 58 is rotated so that the position of the opening 58a is the position of the corpse and dust of the insect, whereby the corpse and dust of the insect existing in the space region 59 can be removed by, for example, a vacuum cleaner through the opening 58 a.

(cleaning and replacement of the Pre-Filter 49)

Fig. 15 is a perspective view showing a state in which the lower cover member 52 is opened and the pre-filter holding member 51 is removed from the blower device 1 in the state shown in fig. 2. Fig. 16 is a perspective view showing a state where lower cover member 52 is removed from blower 1 shown in fig. 15.

When cleaning or replacing the pre-filter 49, as shown in fig. 15, the pre-filter 49 can be removed by opening the lower cover member 52 of the main body 22 and removing the pre-filter holding member 51. The state of fig. 15 is a state in which the lower cover member 52 is opened from the side fixed by the magnet 53 and supported by the side fixed by the V-spring 54. The detached prefilter 49 is cleaned by removing dust with a vacuum cleaner or by washing with water.

As shown in fig. 16, the lower cover member 52 can be detached from the main body 22 by detaching the side fixed by the V-spring 54 from the side fixed by the magnet 53.

(cleaning and replacement of HEPA Filter 44)

Fig. 17 is a perspective view showing a state in which the HEPA filter 44 is removed together with the HEPA filter holding member 50 from the blower 1 in the state shown in fig. 16.

As shown in fig. 17, the blower 1 can remove the HEPA filter holding member 50 holding the HEPA filter 44 from the blower 1. Therefore, when the HEPA filter 44 is cleaned, the HEPA filter holding member 50 is removed from the blower 1 to clean the HEPA filter 44. In addition, when the HEPA filter 44 is replaced, the HEPA filter holding member 50 is similarly removed from the blower 1 together with the HEPA filter 44, and the HEPA filter 44 is replaced.

In addition, in the case of simply cleaning the HEPA filter 44, as shown in fig. 15 or 16, the lower cover member 52 may be opened without removing the HEPA filter holding member 50 from the air sending device 1, and the HEPA filter 44 may be cleaned by, for example, sucking air through the cleaner from the filter suction port 50a of the HEPA filter holding member 50.

(advantages of blower 1)

In the blower device 1, the blower 42, i.e., the fan 47 and the motor 48 for rotating the fan 47 are disposed directly below the ceiling junction box 12, and the centers of the fan 47 and the motor 48 are substantially aligned with the center of gravity of the main body 22 in the vertical direction. In this case, the centers of the fan 47 and the motor 48 coincide with the stoppage of the cylindrical portion 21b of the body supporting member 21 in the vertical direction. Therefore, the blower 1 is mounted in a state in which the weight balance is stabilized.

The main body 22 of the blower 1 is attached to the ceiling junction box 12 via the main body support member 21, the main body support member 21 has an upper portion (upper plate portion 21a) fixed to the ceiling junction box 12, and the main body 22 is fitted to a lower portion (flange portion 21c) and includes an intermediate portion (cylindrical portion 21b) extending in the vertical direction between the upper portion and the lower portion.

Therefore, the blower 1 includes a gap through which air flows between the ceiling 11 and the upper surface of the main body 22, except for the portion of the main body support member 21 having substantially the same diameter as the ceiling junction box 12. Accordingly, the air blower 1 is less likely to obstruct the flow of air of the air conditioner along the ceiling surface, and the air conditioner can maintain a smooth flow of air along the ceiling surface.

In the blower 1, since the fan 47 and the motor 48 are located directly below the ceiling junction box 12, the power cord 25 drawn out from the ceiling junction box 12 has to be connected to the main body 22 outside the main body 22. In this case, in the air blowing device 1, as described above, the gap is formed between the ceiling 11 and the upper surface of the main body 22, and the power cord 25 and the main body 22 can be easily connected by the gap.

In the blower 1, the main body 22 is rotatable at a fitting position to the support member fitting portion 31 of the main body support member 21. Thus, the user can easily change the position of the air outlet 43a, that is, the air blowing direction in the horizontal direction by rotating the main body 22.

Specifically, when the user wants to change the blowing direction of the air from the blowing port 43a (the opening 58a), the user removes the power cord cover 24, lifts the main body 22, and releases the fitting between the fitting protrusion 31a2 of the upper plate portion 31a of the support member fitting portion 31 and the fitting hole 21c1 of the flange portion 21c of the main body support member 21. Next, the user rotates the main body 22 so that the blow-out port 43a (the opening 58a) is at a desired position, and then fits the fitting convex portion 31a2 of the upper plate portion 31a of the support member fitting portion 31 into the fitting hole 21c1 of the flange portion 21c of the main body support member 21. After that, the user mounts the power cord cover 24 in the original state.

In the blower 1, the lower cover member 52 is attached to the main body 22 by the magnet 53 on one end side and the V-shaped spring 54 on the opposite side. Therefore, the lower cover member 52 is opened by separating the magnet 53 side from the main body 22, and the pre-filter 49 can be easily removed from the main body 22. The lower cover member 52 can be easily detached from the main body 22 by detaching the V-spring 54 side from the main body 22, in addition to the magnet 53 side. In the mounting structure of the lower cover member 52 to the main body 22, the coupling portion between the main body 22 and the lower cover member 52 is less visible in appearance than the structure in which the lower cover member 52 is coupled to the main body 22 by a hinge, and the appearance can be improved.

The swing ring 58 including the opening 58a can be rotated to move the position of the opening 58 a. Therefore, when the air blower 1 is not used, the swing blade ring 58 is rotated so that the opening 58a is displaced from the air outlet 43a, whereby intrusion of insects and dust into the air blowing passage 43 can be prevented.

When the body of the worm and the dust are accumulated in the space region 59 along the inner surface of the swing blade ring 58, the swing blade ring 58 is rotated to remove the body of the worm and the dust from the opening 58 a.

The lid upper portion 56b (see fig. 9(a) and 9 (b)) of the illumination lid 56 is in a state in which the annular side wall portion is inclined inward of the illumination lid 56 with respect to the vertical direction. Therefore, light emitted from the LEDs of the illumination substrate 55 toward the cover lower portion 56a is reflected by the inner surface of the cover lower portion 56a, and is transmitted through the cover upper portion 56b and the swing ring 58. Thus, a part of the light emitted from the LED of the illumination substrate 55 can illuminate the ceiling around the blower 1.

The operation state notification device 81 displays the state of contamination of the room detected by the odor sensor 91 on the ceiling 11 (ceiling) by the state display 85. Therefore, the user can easily know the state of the air in the room (contamination state) and the operation of the air blower 1 by the state display 85 displayed on the ceiling without being obstructed by the light of the lighting unit 45 being turned on.

Further, since the status display 85 has a long and narrow shape and is formed in a long range, even when the ceiling surface has a pattern such as unevenness or wood stripes, the user can easily confirm the status display 85.

In addition, the light transmission window 86 may have a convex shape. In this case, the periphery of the light transmission window 86 is also bright in the upper case portion 41, and thus the contamination state of the air in the room can be more easily checked.

The operation state notification device 81 may include a filter or the like for displaying the state display 85 as some image.

In the present embodiment, the blower device 1 is configured to include the main body support member 21, the ion generating element 46, the blower 42 (the fan 47 and the motor 48), the HEPA filter 44, the illumination unit 45, the pre-filter 49, the swing blade ring 58, and the operation state notification device 81, but is not limited to this configuration, and may be configured to include at least the main body support member 21 and the main body 22 including the blower 42. This point is also the same in the following embodiments.

Other embodiments of the present invention will be described below with reference to the drawings. For convenience of explanation, members having the same functions as those described in the above embodiments are given the same reference numerals, and explanations thereof are omitted.

(construction of the swinging blade ring 71)

Fig. 18 is a perspective view showing a swing blade ring 71 included in the air blowing device 2 of the present embodiment. The blower 2 (see fig. 1) according to the present embodiment includes a vane ring (side cover member) 71 shown in fig. 18, instead of the vane ring 58. The vane ring 71 includes an opening 71a instead of the opening 58a of the vane ring 58. The openings 71a are formed at two positions of the swing ring 71, similarly to the openings 58 a.

The height of the opening 71a of the swing blade ring 71 changes stepwise. Specifically, the opening 71a has a length substantially twice that of the opening 58a, and includes a first opening region 71a1 and a second opening region 71a2 that are continuous in the circumferential direction of the swing vane ring 71. The opening heights of the first opening region 71a1 and the second opening region 71a2 are different from each other, and the opening height of the second opening region 71a2 is higher than the opening height of the first opening region 71a1.

In the present embodiment, the opening height of the first opening region 71a1 is set to H1 equal to the opening height of the opening 58 a. In this case, when the first opening region 71a1 is disposed at the position of the outlet 43a, air is blown out from the first opening region 71a1 at an angle of 45 ° obliquely downward with respect to the horizontal direction. The opening height of the second opening region 71a2 is H2, and this opening height H2 is set so that air is blown out from the second opening region 71a2 in a substantially horizontal direction when the second opening region 71a2 is disposed at the position of the air outlet 43a. The other configurations of the air blowing device 2 are the same as those of the air blowing device 1 described above.

(advantages including the swinging blade ring 71)

In the air blowing device 2 including the flap ring 71, the user can change the blowing direction of the air in the vertical direction by rotating the flap ring 71 and changing the opening area of the opening 71a arranged with respect to the air outlet 43a between the first opening area 71a1 and the second opening area 71a2.

Therefore, in a state where the first opening region 71a1 is disposed at the outlet 43a, when the user feels uncomfortable with cold or the like due to direct wind blowing, the swing vane ring 71 is rotated to dispose the second opening region 71a2 at the outlet 43a. This makes it possible to change the blowing direction of the wind to a substantially horizontal direction, thereby eliminating the above-described uncomfortable feeling for the user.

In the air blowing device 2 including the flap ring 71, the blowing direction of the air in the vertical direction can be changed by rotating the main body 22 to change the blowing direction of the air in the horizontal direction and rotating the flap ring 71. Other advantages of the air blowing device 2 are the same as those of the air blowing device 1 described above.

(embodiment mode 3)

Another embodiment of the present invention is described below based on the drawings. For convenience of explanation, members having the same functions as those described in the above embodiments are given the same reference numerals, and explanations thereof are omitted.

The swing blade ring 72 includes an opening 72a instead of the opening 58a of the swing blade ring 58. The openings 72a are formed at two positions of the swing ring 72, similarly to the openings 58 a.

The opening height of the opening 72a of the swing blade ring 72 is changed so as to gradually increase from one end portion to the other end portion in the circumferential direction of the swing blade ring 72. Specifically, the opening height H of the opening 72a changes linearly. The opening 72a has a length approximately twice that of the opening 58a, and the opening 72a has a lower opening height on one end side and a higher opening height on the other end side in the circumferential direction of the swing vane ring 72. The opening 72a has an opening height at one end, for example, H1, and an opening height at the other end, for example, H2. The other configurations of the air blowing device 3 are the same as those of the air blowing device 1.

(advantages including the pendulum blade ring 72)

In the air blowing device 3 including the flap ring 72, the user can change the blowing direction of the air in the vertical direction by rotating the flap ring 72 and changing the area of the opening 72a disposed with respect to the blowing port 43a. In this case, since the opening height H of the opening 72a is continuously changed, the direction of blowing the wind can be continuously changed by rotating the vane ring 72.

Therefore, in the blower 3 including the flap ring 72, in a state where the area with the low opening height of the opening 72a is disposed in the air outlet 43a, when the user feels uncomfortable with cold or the like due to direct blowing, the flap ring 72 is rotated and the area with the high opening height is disposed in the air outlet 43a. This makes it possible to change the blowing direction of the wind to a substantially horizontal direction, thereby eliminating the above-described uncomfortable feeling for the user.

In the air blowing device 3 including the flap ring 72, the blowing direction of the air in the horizontal direction can be changed by rotating the main body 22, and the blowing direction of the air in the vertical direction can be changed by rotating the flap ring 72. Other advantages of the air blowing device 3 are the same as those of the air blowing device 1 described above.
