  • the air conditioner according to the present invention is not a "ceiling-recessed" air conditioner, but is an air conditioner in which a back surface of the main body is placed in contact with or close to a wall surface that delimits the air conditioning target space (a wall rather than a ceiling or a floor), and in which a front surface of the main body is oriented toward the air conditioning target space in question.
  • the air conditioner according to the present invention does not have a suction port and an outlet port in a common plane as in ceiling-embedded types, and may be disposed alongside a wall surface that delimits the air conditioning target space, away from a central portion of the air conditioning target space.
  • the main body 1 is an approximately rectangular parallelepiped housing. Specifically, the main body 1 includes: a back surface 1c that faces the wall 11a of the room 11; a front surface 1a that is on an opposite side from the back surface 1c; an upper surface 1b; a lower surface 1d; and a pair of left and right side surfaces 1e.

  • a first suction port 2a for sucking indoor air into the air conditioner 100 has an opening in a central portion in a main body height direction of the front surface grill 6.
  • the suction port 2a extends along the front surface grill 6 in the width direction, and has an opening that has a length that corresponds to a length in a width direction of at least a heat exchanger 7 (described below).

Furthermore, the suction port 2a is disposed within a range H below an upper end of a crossflow fan 8 (described below) and above than an upper end of a stabilizer 9 (described below) in the main body height direction.
  • a grill-shaped second suction port 2b for sucking indoor air into the air conditioner 100 is formed on an upper surface 1b of the main body 1.
  • An outlet port 3 for supplying conditioned air inside a room is formed on the lower surface 1d and the front surface 1a of the main body 1.
  • the outlet port 3 is formed so as to span the lower surface 1d and the front surface 1a of the main body 1. To put it another way, the outlet port 3 is spread continuously so as to occupy a region on a front portion of the lower surface 1d of the main body 1 and a region on a lower portion of the front surface 1a of the main body 1.
  • the outlet port 3 has an opening only on the lower surface 1d and the front surface 1a of the main body 1, and does not have an opening on the upper surface 1b, the back surface 1c, or the left and right side surfaces 1e.
  • a crossflow fan (a blowing portion) 8 that has an impeller 8a, and a guiding wall 10 are installed inside the main body 1.
  • the crossflow fan 8 is disposed between a suction flow channel E1 and an expulsion flow channel E2, and sucks air in through the suction ports 2a and 2b, and expels the air out through the outlet port 3.
  • the guiding wall 10 extends continuously downward from behind the crossflow fan 8, and directs the air that has been expelled from the crossflow fan 8 to the outlet port 3.
  • a filter (a ventilation resisting body) 5 that removes dust from the air that is sucked in through the suction ports 2a and 2b; a heat exchanger (a heat exchanging portion and ventilation resisting body) 7 that generates conditioned air by transmitting warmth or coldness of a refrigerant to the air; and a stabilizer 9 that partitions the suction flow channel E1 and the expulsion flow channel E2.

  • the outlet air channel 3b on a side near the front surface 1a of the main body 1 is delimited by the diffuser 3a
  • the outlet air channel 3b on a side near the back surface 1c of the main body 1 is delimited by the guiding wall 10, the outlet air channel being formed by the facing diffuser 3a and guiding wall 10.
  • the guiding wall 10 forms a spiral surface from the crossflow fan 8 to the outlet port 3.
  • a filter 5 is formed so as to have a mesh shape, for example, and removes dust from the air that is sucked in through the suction ports 2a and 2b.
  • the filter 5 is disposed downstream from the suction ports 2a and 2b and upstream from the heat exchanger 7 within the air channel from the suction port 2a and 2b to the outlet port 3.
  • the filter 5 extends forward from above the heat exchanger 7.
  • the heat exchanger 7 (the indoor heat exchanger) functions as an evaporator to cool the air during cooling operation, and functions as a condenser (a radiator) to warm the air during heating operation.
  • this heat exchanger 7 is disposed downstream from the filter 5 and upstream from the crossflow fan 8.
  • the shape of the heat exchanger 7 is a shape that surrounds a front portion and an upper portion of the crossflow fan 8, but this is merely one example, and is not particularly limited thereto.
  • the heat exchanger 7 is connected to an outdoor unit that may have conventional features such as including a compressor, an outdoor heat exchanger, and a throttling apparatus, etc., to constitute a refrigeration cycle. Furthermore, a cross fin fin-and-tube heat exchanger that is constituted by a heat exchanging tube and a plurality of fins, for example, can be used as the heat exchanger 7.
  • a vertical wind directing vane 4a and lateral wind directing vanes 4b are disposed in the outlet air channel 3b.
  • the lateral wind directing vanes 4b are disposed pivotably between the vertical wind directing vane 4a and the crossflow fan 8.
  • the vertical wind directing vane 4a adjusts a vertical component of the air that is blown out from the crossflow fan 8
  • the lateral wind directing vanes 4b adjust the direction of the air that is blown out from the crossflow fan 8 to the left and right.
  • the vertical wind directing vane 4a and the lateral wind directing vanes 4b are driven so as to be pivoted independently from each other.
  • the vertical wind directing vane 4a has a convex shape in which an upper surface and a lower surface of the vertical wind directing vane 4a both protrude downward relative to attitude during a horizontal blowing operation.
  • the stabilizer 9 partitions the suction flow channel E1 and the expulsion flow channel E2 as described above, and is disposed below the heat exchanger 7 as shown in Figure 2 .
  • the suction flow channel E1 is positioned above the stabilizer 9, and the expulsion flow channel E2 is positioned below the stabilizer 9.
  • the stabilizer 9 has: a tongue portion 9a that separates the suction flow channel E1 and the expulsion flow channel E2 ; a draining pan 9b that temporarily stores water from droplets that drip down from the heat exchanger 7; and the diffuser 3a.
  • the diffuser 3a is formed on the lower surface of the stabilizer 9 as described above, and functions as an upper wall surface (a front surface-side wall surface) of the outlet air channel 3b of the outlet port 3.
  • Figure 3 is a diagram that relates to Embodiment 1, and that shows portions in a vicinity of a diffuser and a downstream portion of a guiding wall enlarged.
  • an upstream portion 3a1 of the diffuser 3a extends in a direction that is similar or identical to the direction that the downstream portion 10a of the guiding wall 10 extends, such that the upstream portion 3a1 of the diffuser 3a lines up approximately parallel to the downstream portion 10a of the guiding wall 10 when viewed from a side.
  • the upstream portion 3a1 of the diffuser 3a has a rectilinear portion in a side view.
  • a direction of extension of the rectilinear portion of the upstream portion 3a1 of the diffuser 3a is an upstream portion imaginary straight line S1
  • a front portion of that upstream portion imaginary straight line S1 extends so as to intersect with an imaginary straight line F that extends from the front surface 1a of the main body 1.
  • a downstream portion 3a2 of the diffuser 3a extends so as to diverge downward from the upstream portion imaginary straight line S1 increasingly toward a downstream end of the downstream portion 3a2.
  • the diffuser 3a has a portion that diverges from the upstream portion imaginary straight line S1 , which constitutes a direction of extension of the upstream portion 3a1 of the diffuser 3a, increasingly toward a downstream end of the diffuser 3a in a side view.
  • the diffuser 3a is configured so as not to have any portions that are positioned above the upstream portion imaginary straight line S1 of the upstream portion 3a1 of the diffuser 3a.
  • the downstream portion 3a2 of the diffuser 3a has a rectilinear portion when viewed from a side. If a direction of extension of the rectilinear portion of the downstream portion 3a2 of the diffuser 3a is a downstream portion imaginary straight line S2, then the downstream portion imaginary straight line S2 is lower than the upstream portion imaginary straight line S1.
  • the diffuser 3a is bent or curved at a portion 3a3 of the diffuser 3a that is positioned between the upstream portion 3a1 and the downstream portion 3a2.
  • a length A of the rectilinear portion of the downstream portion 3a2 of the diffuser 3a that is shown in Figure 3 is a length that is greater than or equal to half of a length B of a chord that joins the upstream end 4a1 and the downstream end 4a2 of the vertical wind directing vane 4a.
  • angle ⁇ that is formed between the upstream portion imaginary straight line S1 and the downstream portion imaginary straight line S2 is 5 degrees through 40 degrees.
  • Figure 4 is a graph that shows a relationship between angle ⁇ that is formed between an upstream portion imaginary straight line S1 and a downstream portion imaginary straight line S2 and ⁇ SPL.
  • ⁇ SPL is a difference in sound level compared to when angle ⁇ that is formed by the upstream portion imaginary straight line S1 and the downstream portion imaginary straight line S2 is zero degrees, i.e., they are connected in a straight line.
  • the angle ⁇ that is formed between the upstream portion imaginary straight line S1 and the downstream portion imaginary straight line S2 is 5 degrees through 40 degrees, whereby noise from the fan that is deflected by the guiding wall is deflected below the unit due to the wall surface at the downstream end of the diffuser, suppressing noise emission toward the front surface side of the air conditioner, and enabling noise reduction to be achieved.
  • a diffuser has a portion that diverges from an upstream portion imaginary straight line that is a direction of extension of an upstream portion of the diffuser increasingly downstream thereon, flow of expelled air along a wall surface in a downstream portion of the diffuser (the downstream portion of the diffuser) can be accelerated. Because of that, reverse flow from an outlet port to a blower fan can be reduced even during relatively heavy expulsion loads such as ventilation resistance increasing due to dust depositing on a filter that is disposed near suction ports, for example.
  • reverse flow from the outlet port to the blower fan can be reduced, and formation of condensation can also be reduced even during relatively heavier expulsion loads than immediately after factory shipment while still being able to expel conditioned air over a wide area of a target space due to the outlet port spanning across a front surface and a lower surface of a main body.
  • an outlet air channel is constituted by a diffuser and a guiding wall that face each other, flow is stabilized by ensuring a flow channel that functions as a duct, enabling air to be blown stably with respect to changes in environment such as changes in ventilation resistance due to upper and lower flaps being movable, and changes in ventilation resistance due to dust blockage on a filter, etc.
  • Another advantage is that noise from the fan that is reflected by the guiding wall is actively reflected below the main body of the air conditioner by the downstream portion of the diffuser, suppressing noise emission toward a front surface of the air conditioner, and enabling noise reduction.
  • a length A of the rectilinear portion of the downstream portion 3a2 of the diffuser 3a a length that is greater than or equal to half of a length B of a chord that joins the upstream end 4a1 and the downstream end 4a2 of the vertical wind directing vane 4a, flow between the diffuser 3a and the vertical wind directing vane 4a is stabilized, enabling controllability of wind direction to be improved.
  • front surface grill 6 so as to be vertically flat, dust is less likely to attach to the surface of the front surface grill 6, enabling it to be kept clean. Furthermore, by forming the front surface grill 6 so as to be laterally flat, air channel depth is identical across a width direction of the main body 1, enabling the crossflow fan 8 and the heat exchanger 7 to be mounted inside the main body 1 at a high density, thereby enabling fan blowing performance and heat exchanging performance to be improved.
  • the airflow guiding wall 6a By making the airflow guiding wall 6a so as to have an L-shaped cross section, only the downward surface 6a2 is visible inside the air intake apertures 2a in a front view, improving decorative design because a flat surface is visible at a deepest position in a depth direction. Because a buffer area for suction flow is formed at a corner portion between the horizontal surface 6a1 and the downward surface 6a2, suction air is not parallel to a wall surface, making dust less likely to attach.
  • noise from the crossflow fan 8, etc., that is generated inside the main body 1 propagates out of the suction ports 2a, because the upper surface (the horizontal surface 6a1) of the airflow guiding wall 6a is formed so as to be horizontal, noise that is reflected outside is reduced, enabling reduced noise to be ensured.
  • an opening of the suction ports 2a a length that corresponds to a length of a width direction of the heat exchanger 7
  • the air that has been sucked in through the suction ports 2a can exchange heat effectively at the heat exchanger 7.
  • suction pressure loss can be reduced due to the aperture area of the suction ports 2a being increased.
  • the front surface grill 6 is a shape that is divided into top and bottom at a central portion in the main body height direction, and because height dimensions are equal on an upper portion side and a lower portion side of the front surface grill 6, and strength is equal on the upper portion side and the lower portion side, making it unlikely to bend, and enabling quality to be maintained.
  • FIG. 5 is a diagram that relates to Embodiment 2 according to the present invention, that has similar features to Figure 2 .
  • Embodiment 2 is similar or identical to Embodiment 1 except for portions that will be explained below.
  • the diffuser 3a was configured so as not to have any portions that are positioned above the upstream portion imaginary straight line S1 of the upstream portion 3a1 of the diffuser 3a, but the present invention is not limited thereto.
  • the diffuser 3a can be formed such that a portion between the upstream portion 3a1 of the diffuser 3a that determines the upstream portion imaginary straight line S1 and the downstream portion 3a2 of the diffuser 3a that determines the downstream portion imaginary straight line S2 has various shapes.
  • Figure 5 is one example thereof.
  • the diffuser 3a has an intermediate portion 3a4 between the upstream portion 3a1 of the diffuser 3a that determines the upstream portion imaginary straight line S1 and the downstream portion 3a2 of the diffuser 3a that determines the downstream portion imaginary straight line S2.
  • This intermediate portion 3a4 is positioned higher than the upstream portion imaginary straight line S1.
  • Embodiment 2 Similar or identical working effects to those in Embodiment 1 can also be achieved using Embodiment 2 or the like, and in particular formation of condensation can be reduced while having an outlet port that occupies a portion of the lower surface and a portion of the front surface of the main body.
  • FIGS 6 and 7 are diagrams that relate to Embodiment 3 according to the present invention, that have similar features to Figure 3 .
  • Embodiment 3 is similar or identical to Embodiments 1 or 2 except for portions that will be explained below.
  • Figures 6 and 7 are examples of cases that are configured in a similar or identical manner to Embodiment 1 except for portions that will be explained below.
  • the upstream portion of the diffuser 3a and the downstream portion of the guiding wall 10 are in an approximately parallel configuration, but the present invention is not limited thereto.
  • the present invention may have a configuration in which a distance between an upstream portion of a diffuser and a downstream portion of a guiding wall widens gradually downstream.
  • Figures 6 and 7 are examples thereof.
  • the direction in which an upstream portion 303a1 of a diffuser extends is set so as to be further away from a downstream portion 10a of a guiding wall 10 toward a downstream end than the direction in which the upstream portion 3a1 of the diffuser in the configuration in Figure 2 of Embodiment 1 that is described above extends.
  • an outlet air channel in Figure 6 is wider than the outlet air channel in Figure 2 on a side near the upstream portion 303a1 of the diffuser.
  • the direction in which a downstream portion 310a of a guiding wall extends is set so as to be further away from an upstream portion 3a1 of a diffuser 3a toward a downstream end than the direction in which the downstream portion 10a of a guiding wall in the configuration in Figure 2 of Embodiment 1 that is described above extends.
  • an outlet air channel in Figure 7 is wider than the outlet air channel in Figure 2 on a side near the downstream portion 310a of the guiding wall.
  • Embodiment 3 Similar or identical working effects to those in Embodiment 1 can also be achieved using Embodiment 3 or the like, and in particular formation of condensation can be reduced while having an outlet port that occupies a portion of the lower surface and a portion of the front surface of the main body. Because the distance between the upstream portion of the diffuser and the downstream portion of the guiding wall widens toward a downstream end, the fan expulsion flow is expanded in a vicinity of the fan expulsion region 8b, and is made uniform in a height direction of the outlet port. As a result thereof, flow is stabilized, and more stable blowing is enabled relative to ventilation resistance increases due to dust blockage of the filter, enabling improvements in quality.
  • FIG. 8 is a diagram that relates to Embodiment 4 according to the present invention, that has similar features to Figure 2 .

  • the present invention can also be applied to an air conditioner in which the outlet port 3 is formed only on the lower surface 1d of the main body 1, and similar or identical working effects can be achieved.
  • Figure 8 is one example thereof.
  • an outlet port 3 for supplying conditioned air inside a room is formed on the lower surface 1d of the main body 1.
  • the outlet port 3 has an opening only on the lower surface 1d of the main body 1, and does not have an opening on the front surface 1a, the upper surface 1b, the back surface 1c, or the left and right side surfaces 1e.
  • a front surface grill 6 that is equal in height to the main body height direction is mounted to the front surface 1a of the main body 1.
  • a vertical wind directing vane 4a is constituted by two members, but it may be constituted by a single member in a similar or identical manner to Embodiment 1.
