Description

  The present invention relates to an air blower such as a fan or a ceiling fan that is installed on a ceiling, wall, or floor surface in a living room and is used for reducing the temperature of sensation caused by direct airflow or circulating the air in the room.

  Conventionally, this type of air blower includes an impeller and a motor in a base serving as a pedestal, and air is circulated so as to blow out horizontally from an annular air blower provided at the top of the base. In addition, a home blower that generates a flow of air is known (for example, see Patent Document 1).

  Hereinafter, the blower will be described with reference to FIGS. 4 and 5.

  4 is a projection view of the blower assembly 100 as viewed from the front, and FIG. 5 is a cross-sectional projection view of the blower assembly 100. The blower assembly 100 has an annular nozzle 101 that defines a central opening 102. A motor 122 that creates an air flow through the annular nozzle 101 is disposed within the base 116 along with the motor housing 126. Further, the impeller (impeller) 130 is connected to a rotating shaft extending outward from the motor 122, and the motor 122 in which the diffuser 132 is positioned downstream of the impeller 130 is connected to an electrical connection unit and a power source. A plurality of selection buttons 120 allow the user to operate the blower assembly 100.

  With the above configuration, the above-described blower assembly 100 operates as follows.

  The motor 122 is driven by the user appropriately selecting from a plurality of selection buttons 120. Thus, the motor 122 is activated and air is drawn into the blower assembly 100 through the air inlet 124. Air flows through the outer casing 118 to the inlet 134 of the impeller 130. The air flow that exits the outlet 136 of the diffuser 132 and the exhaust portion of the impeller 130 is divided into two air flows that travel in opposite directions through the internal passage 110.

  The air flow is throttled as it enters the mouth 112 and is further throttled at the outlet 144 of the mouth 112. This throttling creates pressure in the system.

  The air flow thus created overcomes the pressure produced by the restriction and the air flow exits through the outlet 144 as the primary air flow. The primary air flow is concentrated or focused toward the user depending on the arrangement of the guide portion 148. The secondary air flow is generated by entrainment of air from the outside environment, particularly from the area around the outlet 144 and around the outer edge of the annular nozzle 101. This secondary air flow passes through the central opening 102 where there is a total air flow that mixes with the primary air flow and is discharged forward from the blower assembly 100.

And a second air passage 24 communicating with the induction air outlet 23. Is, those with a LED light unit 26 as an illuminating means to attract air mixing portion 22 of the second air passage 24. Here, high-pressure air refers to air at atmospheric pressure or higher.

  The second air passage 24 is provided so as to penetrate the first air passage 20 through the through wall 25, and the first air passage 20 includes the outer wall 13, the inner wall 14, and the through wall 25. It is comprised by the inner wall 14 and the penetration wall 25, and the attraction air blower outlet 23 is enclosed by the inner wall 14 which comprises the inner ring of the blower outlet 19, and is comprised.

  Here, the plurality of attraction air inlets 21 are provided radially from the axial center of the air outlet 19, and coaxially passing through the spherical center of the housing 12 at a position where the air inlet 15 and the air outlet 19 face each other. It has a built-in configuration. Moreover, although the housing | casing 12 was represented by spherical shape in this embodiment, as a shape of the housing | casing 12, it is not limited to this in particular, Polyhedron shape (a regular polyhedron and a truncated polyhedron), a column shape, a polygonal column The shape and organic form can be selected freely.

  Moreover, the ring shape of the blower outlet 19 is not limited to a circle, and may be a shape constituted by a polygon or a curve as long as it is a ring. In addition, there is no problem even if the ring shape is partly interrupted by ribs or the like as long as the performance is not affected.

  According to such a configuration, since the impeller 16 is included in the housing 12 so that it cannot be contacted from the outside of the air blower 11, it can be used without worrying about being injured by touching the impeller 16. The operation / stop of the blower 11 can be easily determined even from a remote location. Further, since air is blown out from the second air passage 24 through the attraction air outlet 23, it is easily determined in which direction the airflow is flowing from the attraction air outlet 23 by the light emitted from the LED light unit 26. It is something that can be done.

  Moreover, the LED light unit 26 is provided in the attraction air mixing part 22, The air attracted from the some attraction air inlet 21 is provided with the some attraction air inlet 21 from the axial center substantially radially. Therefore, the air is efficiently mixed at the center of the attraction air mixing unit 22 and is efficiently cooled by the air mixed at the attraction air mixing unit 22.

  Thereby, it can prevent that the LED light unit 26 deteriorates with a heat | fever, and can use an apparatus stably for a long period of time.

  In addition, since there are a plurality of attracting air suction ports 21, performance can be exhibited because air can be attracted from the other attracting air suction ports 21 even in a use state where one attracting air suction port 21 is blocked. Moreover, if the LED light unit 26 that emits light at a wide angle is used, light leaks also from the attraction air suction port 21, so that the blower 11 can be used as indirect lighting in the room.

  In addition, since the suction port 15 and the air outlet 19 are coaxially provided at positions facing each other, the distance between the air inlet 15 and the air outlet 19 is increased, so that the warm air that has cooled the LED light unit 26 is sucked into the air inlet. 15 can be prevented from being sucked again, and the illumination means can be efficiently cooled.

  In addition, although the case of the several attraction air inlet 21 was shown in this embodiment, even if there is one attraction air inlet 21, it is the same effect except the above-mentioned "there is more than one attraction air inlet 21" effect. Is obtained.

As an illuminating means in the induction air mixing section 44 Those with an ED light unit 47. Here, high-pressure air refers to air at atmospheric pressure or higher.

  The LED light unit 47 provided in the blower 31 is directional lighting. Here, as an example, the illumination direction 48 and the blowing direction 49 are set in the same direction.

  According to such a configuration, since the illumination of the LED light unit 47 has directivity, the airflow blown out from the blower 31 is straight forward because the blown air forms a core region in the center. The direction of the airflow is excellent because it is a directional airflow that reaches far away with little attenuation of the wind speed. The air blower 31 can be installed so that the airflow can be easily applied to an arbitrary place by adjusting the direction of illumination.

  In addition, here, as an example, the case where the illumination direction 48 and the air blowing direction 49 are the same direction is shown, but the installation direction of the LED light unit 47 is shifted or inclined to arbitrarily shift the illumination direction 48 and the air blowing direction 49. Therefore, for example, when the air blower 31 is used in a kitchen, it is also possible to apply illumination to the user and air current to the user.

  The air blower according to the present invention can provide an air blower that can be easily discriminated to be operated / stopped from a remote location while eliminating anxiety due to contact by including the impeller. It is useful for various blower devices and lighting devices that are installed on ceilings and walls and used to reduce the temperature of sensation due to direct airflow and to circulate indoor air.
