Definitions

  • the present invention relates to airconditioner decorative panels, to airconditioner vent units, and to airconditioners. More specifically, the invention relates to structures for a horizontal vane, mounted at an air vent, for controlling the direction in which conditioned air is emitted, and to configurations for an air vent at which such a horizontal vane is mounted.
  • horizontal vanes capable of vertically changing the direction in which conditioned air is emitted, are mounted at air vents.
  • the emission direction of conditioned air is oriented relatively downward by the horizontal vanes and, on the other hand, during cooling mode of operation, the emission direction is oriented relatively upward so as to be as parallel as possible to a ceiling surface (so-called a "horizontal emission” operation), with a view to achieving a uniform distribution of room temperature during each mode of operation for the purpose of increasing the efficiency of air-conditioning.
  • a flow of air emitted from an air vent (a) in a state of "horizontal emission” forms a shape approximately similar to a V-shape along the flow, when viewing the airconditioner from a horizontal direction (see Figure 10 ).
  • the velocity of a flow of air emitted at a lengthwise middle portion of the air vent (a) is rapid, so that negative pressure grows stronger, thereby preventing emitted air from reaching a ceiling surface (b) in the vicinity of the air vent.
  • ceiling surface fouling is normally found in regions (D) in close proximity to both sides of the air vent (a) and in approximately a V shape, being directed toward the middle portion from the both ends of the air vent (a) as it leaves away from the air vent (a) (see Figure 2 ).
  • Japanese Patent Application Kokai Gazette No. H03-160266 proposed a technique in which an auxiliary fin operable to change the emission direction to orient in the direction of a ceiling surface is mounted detachably on a horizontal vane. And, the auxiliary fin is installed and removed, depending on the tendency that ceiling fouling occurs.
  • the auxiliary fin is removed and the horizontal vane is oriented downward, for example in an environment likely to cause ceiling fouling because of indoor air that contains dust in large amounts or in a place such as a hospital that requires high levels of contamination prevention.
  • the auxiliary fin is installed so that a horizontal emission operation can be performed, for example in an environment unlikely to cause ceiling fouling or in a place that does not require high levels of contamination prevention.
  • auxiliary fin Even when an auxiliary fin is provided as in the aforementioned prior art example, the auxiliary fin must be removed in an environment likely to cause ceiling fouling. After all, conditioned air is continuously emitted downward from the air vent. This causes a drop in air-conditioning efficiency during cooling mode of operation in which horizontal emission operation should basically be carried out. Besides, there is another problem that cold air falls directly on a person present in a room. This may cause uncomfortable feeling (so-called "draft feeling”) to the person.
  • extension portions (c) are defined at the ends of the air vent (a) as described above
  • a horizontal vane (d) is set in a state of "horizontal emission”
  • this causes air to flow laterally from the lengthwise middle portion toward the ends of the horizontal vane (d) , as indicated by arrows of Figures 11 .
  • the velocity of air emitted from the ends of the air vent (a) is slow, as a result of which the air emitted from the ends of the air vent (a) is likely to reach a ceiling (b) by negative pressure at the middle portion of the air vent (a) . This causes the ceiling surface (b) to become easily dirty.
  • JP-A-8 285 303 discloses a decorative panel for an airconditioner comprising the features of the preamble part of claim 1.
  • the object of the invention is to make it possible to set an adequate emission direction according to the operating status of an airconditioner while, in cases where extension portions are provided at lengthwise ends of ain air vent, preventing ceiling fouling by making improvements in the shape of a horizontal vane mounted at the air vent.
  • the invention provides improvements to horizontal vanes so that conditioned air is guided, in the inside of an extension portion of an air vent, in a direction substantially orthogonal to the lengthwise direction of the air vent. As a result, the conditioned air is unlikely to flow into the extension portion.
  • the invention provides problem-solving means which are premised on a decorative panel for an airconditioner comprising an air vent (16) through which conditioned air is emitted from the direction of a ceiling surface (70) into an indoor space and a horizontal vane (18) , mounted at the air vent (16) , for adjusting the direction in which conditioned air is emitted, on a vent unit for an airconditioner comprising an air vent (16) through which conditioned air is emitted from the direction of a ceiling surface (70) into an indoor space and a horizontal vane (18), mounted at the air vent (16) , for adjusting the direction in which conditioned air is emitted, on an airconditioner comprising the decorative panel (14) which is mounted along a ceiling surface, and on an airconditioner in which the vent unit (51) is mounted on a ceiling surface and is connected, through a fan duct (52) , to an airconditioner main body (53) .
  • the air vent (16) has, in the vicinity of an end thereof, an extension portion (16L) so that the lengthwise opening length of the air vent (16) extends at an area facing an indoor space, and the horizontal vane (18) is so formed that, at a position substantially corresponding to an inside end of the extension portion (16L) of the air vent (16) , conditioned air is guided in a direction substantially orthogonal to the lengthwise direction of the air vent (16) .
  • the inside end of the extension portion (16L) of the air vent (16) is a lengthwise central side end of the extension portion in the air vent (16) and, preferably the position substantially corresponding to the inside end of the extension portion (16L) is a position located slightly more inwardly than the inside end of the extension portion (16L) .
  • conditioned air may be guided in any direction other than the direction in which it (the conditioned air) flows into the extension portion (16L) (the same can be applied to the following).
  • the horizontal vane (18) is provided, at a position substantially corresponding to an inside end of the extension portion (16L) of the air vent (16) , with a guide means (18g) for guiding conditioned air in a direction substantially orthogonal to the lengthwise direction of the air vent (16) .
  • the guide means (18g) may be composed of a guide plate mounted on an upper surface (18f) of the horizontal vane (18) in a state of horizontal emission.
  • the guide plate (18g) is disposed along a direction substantially orthogonal to the lengthwise direction of the horizontal vane (18) ; however, the guide plate (18g) may assume such an inclined position that conditioned air is guided toward the lengthwise center of the air vent (16) .
  • the conditioned air when conditioned air is emitted indoors through the air vent (16) , the conditioned air is guided in an approximately horizontal direction at the middle portion of the air vent (16) at which the emission flow velocity is relatively high, during cooling mode of operation. Further, most of conditioned air, which has struck the horizontal vane (18) , will not flow into the extension portion (16L) because of the guide means (18g) , such as a guide plate, mounted on the upper surface (18f) of the horizontal vane (18) , but it flows along the guide plate (18g) and is emitted in an approximately horizontal direction, still at a high flow velocity.
  • the guide means (18g) such as a guide plate
  • conditioned air striking the horizontal vane (18) flows into the extension portion (16L) ; however, its volume is slight and the volume of air flowing out of the end of the air vent (16) is slight. Because of this, the flow rate of conditioned air, emitted at a slow initial emission velocity and flowing along a ceiling surface, will decrease at the end of the horizontal vane (18) . Further, conditioned air is emitted indoors in downward direction from the entire air vent (16) by adjusting the horizontal vane (18) in downward direction, during heating mode of operation.
  • an airflow upstream side end edge in the vicinity of a lengthwise end of the horizontal vane (18) is so formed that conditioned air is allowed to pass in a region substantially corresponding to the extension portion (16L) of the air vent (16) .
  • an opening portion (18c) may be defined by notching a part of the horizontal vane (18) .
  • conditioned air is guided in an approximately horizontal direction at the middle portion of the air vent (16) at which the emission flow velocity is relatively high.
  • a part of conditioned air after passing through the opening portion (18c) in the vicinity of the end of the horizontal vane (18) , is emitted in a more downward direction at the lengthwise end of the air vent (16) at which the emission flow velocity is relatively slow than at the middle portion. Accordingly, the flow rate of conditioned air, emitted at a slow initial velocity at the end of the air vent (16) and flowing along a ceiling surface, decreases.
  • the air vent (16) is so formed that conditioned air is emitted in a more downward direction at a sidewall (16b-s) of a lengthwise end region of the air vent (16) substantially corresponding to the extension portion (16L) than at a sidewall (16b-c) of a lengthwise middle portion of the air vent (16) .
  • it may be arranged such that the angle of each sidewall of the air vent (16) with respect to the ceiling surface at the lengthwise middle portion differs from that at the lengthwise end.
  • conditioned air is emitted definitely in a more downward direction at the lengthwise ends of the air vent (16) at which the emission flow velocity is relatively slow than at the lengthwise middle portion.
  • the flow rate of conditioned air, emitted at a slow initial velocity and flowing along a ceiling surface decreases.
  • the occurrence of ceiling fouling is prevented while making it possible to allow the emission direction of conditioned air to come closer to a horizontal direction than conventional, particularly during cooling mode of operation which requires horizontal emission of conditioned air.
  • This prevents a resident present in the room from having uncomfortable feeling (draft feeling) while securing air-conditioning efficiency.

  • the notches (18c) as opening portions are formed in the vicinity of the both ends (18e) of the horizontal vane (18) .
  • the opening portions (18c) are not necessarily provided. Even in cases where such opening portions are provided, through holes may be formed in the horizontal vane (18) in place of the notches (18c) .
  • the airflow upstream side end edges may employ any construction as long as conditioned air is emitted in a downward direction at the both ends of the air vent (16) during "horizontal emission" mode of operation.
  • the shape and the dimensions of the horizontal vane (18) and the shape and the dimensions of the notch (18c) (the opening portion) shown above are only examples and therefore can of course be altered properly according to the shape and the dimensions of a product embodied according to the invention.
  • Figures 9A-9C show horizontal vanes (18) having different ends.
  • Figure 9A illustrates an example of the notch (18c) in which airflow upstream side end edges of areas in the vicinity of both lengthwise ends of a horizontal vane (18) are shaped into a circular arc.
  • Figure 9B illustrates another example of the notch (18c) in which airflow upstream side end edges of areas in the vicinity of both lengthwise ends of a horizontal vane (18) are obliquely linearly shaped.
  • Figure 9C illustrates still another example of the notch (18c) in which airflow upstream side end edges of areas in the vicinity of both lengthwise ends of a horizontal vane (18) are formed into a reversed circular arc with respect to the one shown in Figure 9A .
  • Figure 9D shows a substitute for the opening portion (18c) . More specifically, each end of the horizontal vane (18) is formed into a three-dimensionally twisted shape so that the airflow upstream side end edges rise from the lengthwise middle portion toward the both ends of the horizontal vane (18) . In this case, since air is unlikely to separate at the ends of the horizontal vane (18) , the ends of the horizontal vane (18) are unlikely to involve surrounding warm air. This provides an advantage that condensation is unlikely to occur.
  • the inclination of the second outside guide surface (16b) of the air vent (16) is set in such a way that the both ends (16b-s) are inclined at an angle nearer to a vertical than the middle portion (16b-c) .
  • the second outside guide surface (16b) may be inclined, for example throughout the air vent (16) , correspondingly to the inclination of the middle portion (16b-c) of the above-described embodiment.

Abstract

La direction correcte d'une entrée d'air en fonction de l'état de fonctionnement d'un système de climatisation peut être fixée grâce à l'amélioration de la forme d'une grille d'aération horizontale (18) située dans une sortie d'air (16) du système de climatisation. Parallèlement, afin d'éviter le salissement du plafond lorsqu'une partie élargie (16L) est formée au niveau de la partie longitudinale terminale de la sortie d'air (16), une plaque de guidage (18g), destinée à guider le flux d'air conditionné dans une direction globalement perpendiculaire à la direction longitudinale de la sortie d'air (16), est fixée à la grille horizontale (18) dans une position qui correspond sensiblement à l'extrémité intérieure de la partie élargie (16L) du port de sortie d'air (16).
