Definitions

  • the present invention relates to an air conditioner having an air wing that is movable to a position facing an outlet so that draft perception caused by an air-conditioning air flow directly blowing onto someone can be avoided.
  • An air conditioner that is installed at an indoor ceiling has a panel called a ceiling panel or a decorative panel under a unit body, an inlet for sucking indoor air is provided in a central region of a panel body, and multiple outlets for blowing out air-conditioning air flows are open in the downward direction around the inlet. In most cases, the multiple outlets are provided in one direction, two directions, or four directions around the inlet. Furthermore, air-flow direction louvers for adjusting the outlet directions of the air-conditioning air flows are pivotally provided via motors at the individual outlets to allow adjustment of the air-flow directions in arbitrary directions.
  • outlet directions of the air-conditioning air flows are adjustable by means of the air-flow direction louvers provided at the outlets, as described above, depending on the louver angles, etc.
  • An example of a measure for avoiding draft perception in such cases is to additionally install on the panel body, as an optional part, a wing part (hereinafter referred to as an air wing) for interrupting an air-conditioning air flow at a position facing an outlet to change the air-flow direction.
  • a wing part hereinafter referred to as an air wing
  • Patent Literature 1 since an ordinary air-flow-direction control plate is too narrow to sufficiently suppress draft perception by a person under an outlet, a first arm one end of which is pivotally attached to a panel body, a second arm rotatably provided via a link member at the other end of the first arm, a wide air-flow-direction control louver fixed at the distal end of the second arm, and a stopper for regulating rotation with respect to the first arm are provided.
  • pivoting is enabled between a position at which the wide air-flow-direction control louver and the first and second arms are elevated to close the outlet and withdrawn at the panel surface and a position at which the first and second arms are extended downward so that the air-flow-direction control louver faces the outlet to control the air-flow direction.
  • the air wing is additionally installed as an option. For example, it is necessary to separately purchase the air wing. Moreover, once the air wing is installed on the panel body, since the air wing is fixed at a high position near the ceiling, it is not possible to readily change the direction thereof. Furthermore, since the installed air wing remains constantly hoisted (or oriented) downward from the surface of the panel body, the visual impression of the panel body and the ceiling is compromised.
  • the present invention has been made in view of the situation described above, and it is an object thereof to provide an air conditioner having an air wing that allows both air-flow direction control by means of a dedicated louver and suppression of draft perception at the louver position and that has a simple configuration such that smooth operation is ensured and the visual impression of the external design is maintained.
  • a first aspect of the present invention is an air conditioner including an outlet for an air-conditioning air flow, the outlet being provided on a panel body and being open in the downward direction; a louver that is pivotally provided at the outlet in order to adjust an outlet direction of the air-conditioning air flow; an air wing that is provided outside the outlet on the panel body and that is pivotable between a withdrawn position, at which the air wing constitutes a common plane with the panel body, and a louver-direction position, at which the air wing faces the air-conditioning air flow blown out from the outlet; and a pivot mechanism for pivoting the air wing between the withdrawn position and the louver-direction position, wherein the air wing is selectively pivotable between the withdrawn position and the louver-direction position at which draft perception caused by the air-conditioning air flow will be avoided.
  • the air wing that is pivotable between the withdrawn position, at which the air wing constitutes a common plane with the panel body, and the louver-direction position, at which the air wing faces the air-conditioning air flow blown out from the outlet, is provided outside the outlet that is open in the downward direction from the panel body.
  • the air wing is pivotable by the pivot mechanism selectively between the withdrawn position and the louver-direction position.
  • the air wing it is possible to arbitrarily choose to use or not to use the air wing, which makes it possible to readily eliminate discomfort due to draft perception, thereby improving the feeling of air conditioning.
  • the air wing is withdrawn in such a manner as to be integrated with the panel body, so that the impression of the design can be maintained.
  • the air wing may have a wing portion that faces the air-conditioning air flow blown out in the louver direction to interrupt the air flow in the louver direction and may also have arm portions that are provided integrally on either end of the wing portion and whose proximal ends are pivotally supported on the panel body.
  • the air wing has the wing portion that faces the air-conditioning air flow blown out in the louver direction to interrupt the air flow in the louver direction and also has the arm portions that are provided integrally on either end of the wing portion and whose proximal ends are pivotally supported on the panel body, it is possible to interrupt and change the air-conditioning air flow in the louver direction by pivoting the wing portion to the louver-direction position via the arm portions pivotally supported on the panel body so that the wing portion faces the air-conditioning air flow blown out from the outlet.
  • This makes it possible to selectively alleviate or eliminate draft perception by pivoting the air wing to the louver-direction position as needed while maintaining the air-flow-direction control function of the louver provided at the outlet.
  • the wing portion may have a subwing that comes to a position along the wing portion when the air wing is pivoted to the withdrawn position and that stands at a position facing the air-conditioning air flow when the air wing is pivoted to the louver-direction position facing the air-conditioning air flow.
  • the wing portion has a subwing that comes to a position along the wing portion when the air wing is pivoted to the withdrawn position and that stands at a position facing the air-conditioning air flow when the air wing is pivoted to the louver-direction position facing the air-conditioning air flow, irrespective of the pivot angle of the air wing itself, the subwing stands at the position facing the air-conditioning air flow when the wing portion is pivoted to the louver-direction position, so that the air-conditioning air flow is interrupted reliably. Furthermore, since the subwing comes to the position along the wing portion when the wing portion is pivoted to the withdrawn position, the subwing does not hinder withdrawal. Accordingly, it is possible to reliably attain the effect of reducing draft perception by means of the air wing.
  • the panel body may be provided with multiple outlets of the type described above, and air wings of the type described above may be provided in association with the individual outlets.
  • the multiple outlets are provided on the panel body and the air wings are provided in association with the individual outlets, it is possible to alleviate draft perception by individually causing the air wings to function with the air-conditioning air flows blown out from any of the multiple outlets provided, for example, in two directions or four directions. Accordingly, it is possible to selectively alleviate or eliminate draft perception irrespective of which one of the multiple outlets a person is under.
  • the air wings may be individually pivotable by pivot mechanisms of the type described above, the pivot mechanisms being provided independently of each other.
  • the air wings are pivotable individually by the pivot mechanisms that are provided independently of each other, even in the case where a person perceives a draft due to the air-conditioning air flow blown out from one of the outlets because the louver positions at the multiple outlets vary, it is possible to individually pivot the air wing provided in association with the relevant outlet to the predetermined louver-direction position by using the associated independent pivot mechanism.
  • the air conditioner in which the louvers provided at the multiple outlets are individually pivotable it is possible to alleviate or eliminate draft perception as needed by individually pivoting the air wings in association with the individual louver positions.
  • the air wing may be configured to be pivotable to a position corresponding to the position of the louver via the pivot mechanism when an instruction to pivot to the louver-direction position facing the air-conditioning air flow is issued.
  • the air wing is configured to be pivotable to a position corresponding to the position of the louver via the pivot mechanism when an instruction to pivot to the louver-direction position facing the air-conditioning air flow is issued, when alleviating draft perception by pivoting the air wing, it is possible to reliably pivot the air wing to a position corresponding to the pivot position of the louver, thereby placing the air wing at the position facing the air-conditioning air flow blown out in the louver direction. Accordingly, it is possible to reliably attain the effect of alleviating or eliminating draft perception by pivoting the air wing to the position corresponding to the louver position irrespective of the pivot position of the louver.
  • the pivot mechanism may be a wire-based pivot mechanism including an actuator that is provided in the proximity of a pivot point at one end of the air wing on the panel body and that can be rotated forward and backward, a reel that is provided on an output shaft of the actuator, and a wire one end of which is connected to the reel so that it can be wound and unwound and the other end of which is connected to the proximity of a pivot point at the other end of the air wing via wire guides individually provided at a position on the panel body corresponding to one end of the air wing, a position at the one end of the air wing, a position at the other end of the air wing, and a position on the panel body corresponding to the other end of the air wing.

  • the pivot mechanism may be a gear-based pivot mechanism including a rotary shaft that extends in a lengthwise direction of the air wing and whose ends are pivotally supported individually on the panel body, an actuator that can be rotated forward and backward, and a gear mechanism that transmits the rotation of the actuator to the rotary shaft.
  • the pivot mechanism is a gear-based pivot mechanism including a rotary shaft that extends in a lengthwise direction of the air wing and whose ends are pivotally supported individually on the panel body, an actuator that can be rotated forward and backward, and a gear mechanism that transmits the rotation of the actuator to the rotary shaft.
  • a gear-based pivot mechanism including a rotary shaft that extends in a lengthwise direction of the air wing and whose ends are pivotally supported individually on the panel body, an actuator that can be rotated forward and backward, and a gear mechanism that transmits the rotation of the actuator to the rotary shaft.
  • the present invention in the case where an air-conditioning air flow blown out from an outlet directly blows on someone under the outlet depending on a louver position, whereby the person perceives a draft, it is possible to alleviate draft perception by pivoting the air wing provided outside the outlet to the louver-direction position facing the air-conditioning air flow blown out from the outlet and interrupting and changing the air-conditioning air flow in the louver direction.

Furthermore, the rotary shaft 42 is linked via link arms close to the proximal ends of the arm portions 19 on either end pivotally supported via the support shafts 20.
  • the reduction gear mechanism 45 transmits the rotation of the actuator 41 to the rotary shaft 42.
  • the four gear-based pivot mechanisms 40 configured as described above are provided individually in association with the air wings 17 provided for the outlet 14.
  • the four pivot mechanisms 40 make it possible to individually and independently pivot the air wings 17 selectively between the withdrawn positions and the louver-direction positions.
  • the rotary shaft 42 extends in the lengthwise direction of the air wing 17 and pivotally supports either end of the air wing 17 with respect to the panel body 3, allowing simultaneous pivoting of the arm portions 19 on either end.
  • the subwing 21 provided on the wing portion 18 of each of the air wings 17 has the support shafts 22 on either end pivotally supported by the bearings 23 provided on the wing portion 18. Furthermore, the subwing 21 is installed so as to be constantly urged to pivot in a standing direction via coil springs 24 provided between the wing portion 18 and the subwing 21, for example, at three points along the lengthwise direction of the subwing 21.
  • the pivot mechanism 40 is a gear-based pivot mechanism constituted of the rotary shaft 42 that extends along the lengthwise direction of the air wing 17 and whose ends are pivotally supported individually on the panel body 3, the actuator 41 that can be rotated forward and backward, and the gear mechanism 45 that transmits the rotation of the actuator 41 to the rotary shaft 42 and this configuration, the actuator 41 is rotated forward or backward to rotate the rotary shaft 42 via the reduction gear mechanism 45.
  • This makes it possible to simultaneously pivot the arm portions 19 on either end of the air wing 17 via the single rotary shaft 42 to either the withdrawn position or the louver-direction position.
  • the air wings 17 are provided in the air outlet path and are cooled by cool air during cooling operation, the occurrence of condensation due to contact with indoor air is anticipated.
  • insulators for preventing condensation may be attached as needed.
  • actuators 16 for the louvers 15 and the actuators 27 and 41 for the air wings 17 may be implemented commonly so that the louvers 15 and the air wings 17 can be pivoted by common actuators via link mechanisms.
