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.
  • Horizontal vanes capable of vertically changing the direction in which conditioned air is emitted, are conventionally mounted at an air vent of an airconditioner of the ceiling flush mounting type or the duct type.
  • 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 no air reaches 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 toward 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 fouling 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 an 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.
  • an object of the invention is to make it possible to set an adequate emission direction according to the operating status of an airconditioner while preventing ceiling fouling by making improvements in the shape of a horizontal vane mounted at an air vent.
  • the shape of a horizontal vane is improved in such a way that the emission direction of conditioned air from both lengthwise side portions of an air vent is more downwardly oriented than that at a lengthwise middle portion of the air vent.
  • 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 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 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 horizontal vane (18) has, at airflow upstream side end edges of both lengthwise ends thereof, opening portions (18c) through which conditioned air is allowed to pass.
  • the opening portions (18c) may be notches formed at the airflow upstream side end edges of the both lengthwise ends of the horizontal vane (18) .
  • portions equivalent to the opening portions (18c) may be provided at the both ends of the horizontal vane (18) by forming the horizontal vane (18) into a three-dimensionally twisted shape so that the airflow upstream side end edges gradually rise from the lengthwise middle portion toward the both ends.
  • portions equivalent to the opening portions (18c) may be provided by forming the airflow upstream side end edges of the horizontal vane (18) in such a way that the flow rate of air flowing on the side of a negative pressure surface of the horizontal vane (18) is greater at the both ends than at the lengthwise middle portion of the horizontal vane (18) .
  • 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) of a relatively high emission velocity during cooling mode of operation whereas, at the both lengthwise ends of the air vent (16) of a relatively low emission velocity, a part of the conditioned air, after passing through the opening portions (18c) and so on, of the both ends of the horizontal vane (18) , is emitted in a more downward direction than at the middle portion.
  • the horizontal vane (18) is formed into a shape (i.e., a downwardly projecting shape) which bends, from an upstream side to a downstream side of a flow of air emitted, toward a wall surface of the air vent (16) on one of crosswise sides thereof and the one crosswise side wall surface of the air vent (16) bends in the same direction that the horizontal vane (18) does.
  • the shape of the one crosswise side wall surface is not necessarily limited to a bent shape. Any shape may be used as long as it is formed along the horizontal vane (18) .
  • the other crosswise side wall surface may be formed into a more gently bent shape than the one crosswise side wall surface or may be formed into a straight shape.
  • the air vent (16) in cases where the air vent (16) has extension portions (16L) (see Figure 9) so that the lengthwise opening length of the air vent (16) extends at areas facing an indoor space, it may be arranged such that the opening portions (18c) of the horizontal vane (18) are formed in regions corresponding to the extension portions (16L) of the air vent (16) .
  • This can be applied to cases where the airflow upstream side end edges gradually rise from the lengthwise middle portion side toward the both ends of the horizontal vane (18) as well as to cases where the airflow upstream side end edges of the horizontal vane (18) are so formed that the flow rate of air flowing on the negative pressure surface side of the horizontal vane (18) increases.
  • it may be arranged such that these portions are formed in regions corresponding to the extension portions (16L) of the air vent (16) .
  • the opening portions (18c) at the both lengthwise ends of the horizontal vane (18) are notches or if the horizontal vane (18) is so formed that its airflow upstream end edges gradually rise from the lengthwise middle portion toward the both ends, this makes it possible to prevent ceiling fouling with a simple structure. Furthermore, if the dimensions of the opening portions (18c) and so on are set to adequate values, this makes it possible to allow conditioned air to be emitted at the both ends of the air vent (16) at an adequate ratio in a downward direction. This easily realizes a construction capable of providing "horizontal emission" as a whole while preventing ceiling fouling without fail.
  • FIG. 1 is a vertical section showing an arrangement of the ceiling flush type airconditioner (1) according to an embodiment of the invention.
  • the airconditioner (1) comprises a casing (10) in which are housed a fan (20) and a heat exchanger (30) .

  • the main body casing (11) is fixedly suspended from an overlying beam or the like by the use of a hanging ring, which is not shown in the Figure. More specifically, the main body casing (11) is made up of an octagonally shaped top plate (12) formed by notching, in a chamfering manner, four corners of a square plate (not shown) and side plates (13) extending downward from the outer edges of the top plate (12) .
  • the decorative panel (14) has a plate having a substantially square shape and is attached to the lower ends of the side plates (13) of the main body casing (11) .
  • the decorative panel (14) is attached along the ceiling board (70) so that its periphery is brought into abutment with a lower surface of the ceiling board (70) .
  • an air inlet (15) is formed in a substantially central part of the decorative panel (14) so as to open squarely. Formed immediately outside the four sides of the air inlet (15) and in parallel therewith are four rectangular air vents (16). And, the air inlet (15) is provided, all over its surface, with an air filter (17) for removal of suspended substances such as particulate dust contained in indoor air. The entire lower surface of the air filter (17) is supported by a lattice filter cover.
  • an outside guide surface of the decorative panel (14) which is a side wall on the panel outer peripheral side (on the right-hand side in the Figures) of an air passageway in communication with the air vent (16) , is made up of a first outside guide surface (16a) extending substantially vertically downward and a second outside guide surface (16b) inclining, from the lower end of the first outside guide surface (16a) to the lower surface of the decorative panel (14), obliquely in a downward direction toward the panel outer periphery.
  • These outside guide surfaces (16a, 16b) are joined together smoothly.
  • the second outside guide surface (16b) comprises a middle portion (16b-c) located longitudinally centrally in the air vent (16) and both ends (16b-s) located at both lengthwise ends of the air vent (16).
  • the inclination of the middle portion (16b-c) is set at relatively large values (an angle of about 60 degrees), whereas the inclination of the both ends (16b-s) is set at relatively small values (an angle of about 30 degrees).
  • the inclination of the second outside guide surface (16b) varies gradually from the middle portion (16b-c) toward the both ends (16b-s).
  • Figure 5 which is a perspective view of the air vent (16) when viewed from below, the second outside guide surface (16b) further comprises a lower end edge (16b-e) shaped like a circular arc.
  • an inside guide surface of the decorative panel (14) which is a side wall on the panel inner peripheral side (on the lefthand side in the Figures) of an air passageway in communication with the air vent (16) , is made up of a first inside guide surface (16c) extending substantially vertically downward and a second inside guide surface (16d) gently inclining obliquely downward toward the panel outer periphery from the lower end of the first inside guide surface (16c) .
  • These inside guide surfaces (16c, 16d) are joined together smoothly.
  • outside guide surfaces (16a, 16b) are formed in an outside member (14a) of the decorative panel (14)
  • inside guide surfaces (16c, 16d) are formed in an inside member (14b) of the decorative panel (14)
  • outside guide surfaces (16a, 16b) of the outside member (14a) located on the airflow downstream side of the horizontal vane (18) bend substantially conformingly to the cross-sectional shape of the horizontal vane (18 ) (the shape is not limited to such a bent one and any shape may be used as long as it substantially conforms to that of the horizontal vane (18) ).
  • the inside guide surfaces (16c, 16d) of the inside member (14b) located on the airflow upstream side of the horizontal vane (18) are so formed as to extend more vertically downward than the outside guide surfaces (16a, 16b) of the outside member (14a).

  • the shape of the inside guide surfaces (16c, 16d) is a matter of choice.
  • these two wall surfaces (the outside guide surfaces (16a, 16b) and the inside guide surfaces (16c, 16d)) having the aforesaid shapes and lying face to face with each other), are formed so as to stretch the lengthwise length of the air vent (16) (i.e., in a direction normal to the paper surface of the Figure).
  • the air passageway defined between the wall surface (16a, 16b) and the wall surface (16c, 16d) has a function of serving as an "approach way" for adjusting a conditioned air flow while changing the direction of the conditioned air flow.

  • the horizontal vane (18) is so set as to be oriented upward, as shown in Figure 3.
  • the present embodiment is characterized in that notches (18c) as opening portions through which conditioned air is allowed to pass are defined at airflow upstream side end edges of both lengthwise ends of the horizontal vane (18) .
  • the length of each notch (18c) is approximately a quarter of the lengthwise length of the horizontal vane (18) .
  • These notches (18c) are formed at the airflow upstream side end edges of the both lengthwise ends of the horizontal vane (18) , respectively. Because of the provision of the notches (18c) , the horizontal vane (18) has such a shape that the both ends (18e) have a narrowed width about two thirds of that of the middle portion (18d) .
  • the horizontal vane (18) may have for example the following specific dimensions.

  • a drive shaft (26) of the fan motor (25) mounted on the top plate (12) of the main body casing (11) is fixedly inserted in the hub (22) of the fan (20).
  • the fan (20) is rotationally driven by driving force of the fan motor (25), whereby air withdrawn from below the fan (20) is delivered radially laterally.
  • a bell-mouth (27) for guiding, to the fan (20) , air that has flowed into the inside of the casing (10) through the air inlet (15), is provided underneath the fan (20).
  • the heat exchanger (30) is a so-called cross fin heat exchanger made up of a large number of plate-like fins (31) which are arranged in parallel with each other and a heat transfer pipe (32) so arranged as to pass through the fins (31).
  • the heat exchanger (30) is constructed into a rectangular cylinder, when viewed from top, so as to surround the periphery of the fan (20).
  • the heat exchanger (30) is connected, through a refrigerant pipe (not shown), to an outdoor unit.
  • the heat exchanger (30) functions as an evaporator during cooling mode of operation and as a condenser during heating mode of operation, for controlling the temperature state of air delivered from the fan (20).
  • a drain pan (33) for receiving drain water is disposed under the heat exchanger (30) .
  • an air circulation passageway (W) extending from the air inlet (15) of the decorative panel (14) to the air vent (16) by way of the air filter (17) , the bell-mouth (27) , the fan (20), and the heat exchanger (30) , is defined in the inside of the main body casing (11) of the airconditioner (1) .
  • indoor air taken into the inside of the casing (10) from the air inlet (15) through the air filter (17) flows in the bell-mouth (27) , in the fan (20) , and in the heat exchanger (30) in that order in the air circulation passageway (W) .
  • the indoor air exchanges heat with refrigerant in the heat exchanger (30) and is temperature controlled (cooled during cooling mode of operation and heated during heating mode of operation). Thereafter, the air is emitted, as conditioned air, into an indoor space. In this way, the indoor space is air-conditioned.
  • the horizontal vane (18) is oriented substantially vertically downward (see Figure 4 ) so that conditioned air is made to flow along the horizontal vane (18) between the panel outer peripheral side sidewall (16a, 16b) and the panel inner peripheral side sidewall (16c, 16d) of the air vent (16) and is discharged in a downward direction as indicted by Arrow S of the Figure.
  • the horizontal vane (18) is turned in an upward direction (see Figure 3 ) so that the inside surface (18f) of the horizontal vane (18) becomes substantially parallel with the middle portion (16b-c) of the second outside guide surface (16b) of the air vent (16) .
  • conditioned air flows curvedly along the middle portion (18d) of the horizontal vane (18) at the middle portion of the air vent (16) and the direction of its line of flow varies greatly and smoothly.
  • Arrow S1 of the Figure the conditioned air passes between the second outside guide surface (16b) on the panel outer peripheral side of the air vent (16) and the horizontal vane (18) .
  • the conditioned air is emitted through the air vent (16) at such an emission angle as parallel as possible to the lower surface of the ceiling board (70) (for example, at angles of from 30 to 35 degrees with respect to the ceiling board's (70) lower surface).
  • both ends (16b-s) of the second outside guide surface (16b) have a more raised shape (i.e., a less inclined shape) than the middle portion (16b-c), air emitted at the both ends of the air vent (16) is more unlikely to flow in the S 1 direction.
  • air emitted at the both ends of the air vent (16) is unlikely to flow along the lower surface of the ceiling board (70) during cooling mode of operation that especially requires a "horizontal emission” of conditioned air. Therefore, even when the emission direction of conditioned air emitted through the air vent (16) is varied by the horizontal vane (18) so that the angle formed between the conditioned air emission direction and the lower surface of the ceiling board (70) is made to come near to, for example, about 30 to about 35 degrees at the middle portion of the air vent, the occurrence of ceiling fouling can be prevented.
  • each notch (18c) of the horizontal vane (18) is formed only in a region of each end (18d) of the horizontal vane (18) whose length is about a quarter of that of the horizontal vane (18) , which makes it possible to achieve, in totality, a satisfactory "horizontal emission” operation while at the same time preventing the occurrence of ceiling fouling.
  • 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 invention is not limited to the above-mentioned embodiment.
  • the invention includes other various embodiments.
  • the notches (18c) as opening portions are formed at the both ends (18e) of the horizontal vane (18) .
  • through holes may be formed in the horizontal vane (18) in place of the notches (18c) .
  • any construction capable of causing air to be emitted in a downward direction at the both ends of the air vent (16) during "horizontal emission” mode of operation, can be employed.
  • the shape and the dimensions of the horizontal vane (18) and the shape and the dimensions of the notch (18c) 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 7A-7C shows one ends of different horizontal vanes (18)).
  • Figure 7A illustrates an example of the notch (18c) in which airflow upstream side end edges of both lengthwise ends of a horizontal vane (18) are shaped into a circular arc.
  • Figure 7B illustrates another example of the notch (18c) in which airflow upstream side end edges of both lengthwise ends of a horizontal vane (18) are obliquely linearly shaped.
  • Figure 7C illustrates still another example of the notch (18c) in which airflow upstream side end edges of both lengthwise ends of a horizontal vane (18) are formed into a reversed circular arc with respect to the one shown in Figure 7A.
  • Figure 7D shows a substitute for the opening portion (18c) . More specifically, each end of a 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 horizontal vane (18) has airflow upstream side end edges which are formed into such a shape that the flow rate of air flowing on a negative pressure side of the horizontal vane (18) (a downward airflow (see S2 of Figure 3) on the backside of the horizontal vane (18) (on the side of the inside guide surfaces (16c, 16d) of the air vent (16) , i.e., on the emission direction inside)) is greater at the both ends than at the lengthwise middle portion.
  • the invention is applied to the airconditioner (1) of a so-called ceiling flush four-direction emission type which is provided with a turbofan and which emits conditioned air in four directions.
  • the invention is not limited to such an application.
  • the invention is applicable to an airconditioner of a so-called ceiling flush two-direction emission type which emits conditioned air in two directions.
  • the invention is applicable not only to ceiling flush type airconditioners but also to duct type airconditioners.
  • the duct type airconditioner (50) is an airconditioner in which a vent unit (51) mounted on the ceiling board (70) is connected, through a fan duct (52) , to an airconditioner main body (53) mounted on a building roof or the like.
  • the vent unit (51) of the airconditioner (50) the same effects as obtained in the above-described embodiment can be obtained by provision of any one of the opening portions (18c) shown in Figures 7A-7D at each lengthwise end of the horizontal vane (18) .
  • opening portions (18c) such as notches formed at airflow upstream side end edges of both lengthwise ends of a horizontal vane (18) or portions equivalent to the opening portions (18c) have a length corresponding to that of the extension portions (16L) of the air vent (16).
  • opening portions (18c) or the like or when the length of the opening portions (18c) is short air emitted is likely to stay at the both ends of the horizontal vane (18).
  • 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.
