Definitions

  • the present invention relates to an air conditioner outdoor unit and more specifically to measures to deal with the flow of air emitted from a fan of such an air conditioner outdoor unit.
  • an air conditioner outdoor unit known in the prior art which includes a box-shaped casing, and the casing has an air suction inlet at the front and an air emission outlet at the topside.
  • One such air conditioner outdoor unit is disclosed in Japanese Patent Application Kokai Publication No. (2000)18649.
  • This type of air conditioner outdoor unit includes an air conditioner outdoor unit that contains, in its casing, a heat exchanger at the front thereof and a fan disposed on the rear surface side of the heat exchanger, wherein air drawn in from the front of the casing is blown up to the topside of the casing.
  • the heat exchanger is located interior to the air suction inlet formed at the front of the casing, and the fan is at the back of the heat exchanger.
  • the fan comprises a fan rotor and a drive motor disposed on the rear surface side of the fan, wherein the fan rotor is supported on a motor shaft of the drive motor.
  • the drive motor is secured, via a motor stand, to a back plate of the casing. Formed between the fan and the back plate of the casing is an air flow path along which air emitted from the fan flows from bottom to top.
  • air emitted from the fan flows along the air flow path from bottom to top and is discharged to the outside through the air emission outlet formed in the topside. Since the drive motor lies in the air flow path, this causes air emitted to below the drive motor to pass through the periphery of the drive motor and through the periphery of the motor stand. Consequently, the drive motor and the motor stand contribute to the turbulence of the flow of air. In the air flow path, the drive motor and the motor stand become obstacles to a current of air emitted from the fan. This gives rise to problems, such as an increase in noise and a decrease in air supplying volume.
  • an object of the present invention is to reduce resistance to the flow of air emitted from the fan and moving along an air flow path.
  • the present invention employs an arrangement in which a drive motor (53) is disposed on the front side of a fan rotor (52) .
  • a first problem solving means is directed to an air conditioner outdoor unit that comprises a casing (10) including a front-side part (16) in which is formed an air suction inlet (26) and a topside part (14) in which is formed an air emission outlet (21) , a heat exchanger (30) mounted in the air suction inlet (26) of the casing (10) , and a fan (51) mounted on the side of a rear surface of the heat exchanger (30) and including a drive motor (53) and a fan rotor (52) which is activated by the drive motor (53) , and an emission flow path (27) is formed along which a part of air emitted from the fan (51) flows between the fan (51) and a back plate (11) of the casing (10) toward the air emission outlet (21) on the side of a rear surface of the fan (51) .
  • the fan (51) is mounted in such a way that the drive motor (53) is located nearer to the front-side part (16) than the fan rotor (52) .
  • a tube plate (35) for the securing of a heat transfer tube (32) of the heat exchanger (30) is provided and the drive motor (53) is secured, via a motor stand (54) , to the tube plate (35) .
  • the fan (51) is a mixed flow fan.
  • a guide plate (46) for guiding air emitted downward from the fan (51) in such a way that the emitted air flows upward along the back plate (11) , is mounted in parallel with the back plate (11) in the emission flow path (27) .
  • the fan (51) serves as a first fan and a second fan (55) is disposed above the first fan (51) , and a guide plate (46) , for guiding air emitted downward from the first fan (51) so that the emitted air flows upward along the back plate (11) , is mounted in parallel with the back plate (11) in the emission flow path (27) between the first fan (51) and the back plate (11) of the casing (10) , and a flow path separating plate (48) , for the separation of a first flow path (27a) for air emitted from the first fan (51) and flowing upward and a second flow path (27b) for air emitted from the second fan (55) , is disposed on the side of a rear surface of the second fan (55) .
  • air is drawn into the casing (10) through the air suction inlet (26) formed in the front-side part (16) of the casing (10) , when the fan rotor (52) is activated by the drive motor (53) .
  • the air drawn into the casing (10) passes through the heat exchanger (30) and then passes through the periphery of the drive motor (53) . Thereafter, the air is emitted from the fan (51) and becomes a blowoff.
  • a part of the air flows upward along the emission flow path (27) between the fan (51) and the back plate (11) of the casing (10) and is discharged to the outside through the air emission outlet (21) formed in the topside part (14) of the casing (10) .
  • air drawn into the casing (10) through the air suction inlet (26) passes through the heat exchanger (30) .
  • the air After having passed through the heat exchanger (30) , the air passes through the periphery of the motor stand (54) and through the periphery of the drive motor (53) and is emitted by the fan (51) .
  • the air after having passed through the heat exchanger (30) , passes through the periphery of the drive motor (53) . Thereafter, the direction of flow of the air is changed by the mixed flow fan (51) and, as a result, is so emitted as to expand in a radial pattern. Air emitted downward from the mixed flow fan (51) flows upward along the emission flow path (27) between the mixed flow fan (51) and the back plate (11) of the casing (10) and is discharged to the outside through the air emission outlet (21) .
  • air emitted upward from the fan (51) is discharged to the outside through the air emission outlet (21) without flowing between the back plate (11) and the guide plate (46) .
  • air emitted downward from the fan (51) is so guided by the guide plate (46) as to flow upward through the emission flow path (27) along the back plate (11) and is discharged to the outside through the air emission outlet (21) .
  • air is drawn into the casing (10) through the air suction inlet (26) when both the fans (51, 55) are activated by the drive motors (53) , then passes through the heat exchanger (30) , and thereafter passes through the periphery of the drive motor (53) .
  • Air emitted downward from the first fan (51) is guided by the guide plate (46) and flows upward in the emission flow path (27) along the back plate (11) .
  • the air flows along the first flow path (27a) between the flow path separating plate (48) and the back plate (11) and is discharged to the outside through the air emission outlet (21) .
  • air emitted from the second fan (55) flows along the second flow path (27b) and is discharged to the outside through the air emission outlet (21) .
  • the drive motor (53) is located nearer to the front-side part (16) than the fan rotor (52) , so that there is no obstacle to a current of air emitted from the fan (51) in the emission flow path (27) .
  • This accordingly allows the air emitted from the fan (51) to smoothly flow along the emission flow path (27) between the fan (51) and the back plate (11) because the drive motor (53) is not an obstacle.
  • the drive motor (53) is fixed by the tube plate (35) , thereby ensuring that the drive motor (53) is fixed firmly even when the heat exchanger (30) is disposed at the front.
  • the fan (51) is implemented by a mixed flow fan, so that the width of the emission flow path (27) between the back plate (11) and the mixed flow fan (51) can be made narrower in comparison with the case where the fan (51) is implemented by an axial flow fan. This makes it possible to provide an outdoor unit of smaller depth. Furthermore, it is possible to increase the volume of air drawn into the casing (10) in comparison with the case where the fan (51) is implemented by a centrifugal fan.
  • the guide plate (46) for the guiding of air emitted downward from the fan (51) is provided.
  • the emitted air is allowed to smoothly flow into between the guide plate (46) and the back plate (11) of the casing (10) as well as to smoothly flow upward.
  • the volume of air emission from the fan (51) is increased.
  • the fifth problem solving means it is arranged such that the two fans (51, 55) are disposed one above the other. As the result of such arrangement, it becomes possible to increase the volume of air emission without having to increase the area required for installing an air conditioner outdoor unit. Additionally, the provision of the guide plate (46) makes it possible to allow air emitted downward from the first fan (51) to smoothly flow into between the guide plate (46) and the back plate (11) of the casing (10) and to smoothly flow upward. As the result of this, the volume of air emission from the first fan (51) is increased.
  • the first flow path (27a) along which air emitted from the first fan (51) flows upward and the second flow path (27b) along which air emitted from the second fan (55) flows are separated from each other.
  • these flows of air emitted respectively from the fans (51, 55) will not interfere with each other and therefore advance smoothly. Accordingly, the volume of air emission from each fan (51, 55) is increased.

The position of the lower end of the separator plate (46) is adjusted such that air emitted downward from the fan (51) smoothly flows into between the separator plate (46) and the back plate (11) . Stated another way, if the lower end position of the separator plate (46) is situated too low, then the separator plate (46) becomes resistance against air flowing into between the separator plate (46) and the back plate (11) .
  • the separator plate (46) fails to guide air to flow between itself and the back plate (11) . Accordingly, the separator plate (46) is mounted such that its lower end is situated at a predetermined position.

  • the air After having passed through the heat exchanger (30) , the air passes through the periphery of the motor stands (54) and through the periphery of the fan motors (53) , is drawn by the fans (51, 55) , and is blown into the downstream chamber (43) .
  • Air emitted upward from the first fan (51) flows along the first flow path (27a) defined between the back plate (11) of the casing (10) and the flow path separating plate (48) and is discharged, through the emission outlets (21, 23, 25) to outside the casing (10) .
  • air emitted downward from the first fan (51) reverses its course and flows upward, is guided by the separator plate (46) , and flows along the emission flow path (27) .
  • the air flows upward between the back plate (11) of the casing (10) and the separator plate (46) , flows along the first flow path (27a) together with the air emitted upward from the first fan (51) , and is discharged to outside the casing (10) through the emission outlets (21, 23, 25) .
  • Air emitted upward from the second fan (55) flows along the second flow path (27b) defined between the flow path separating plate (48) and the partitioning plate (41) and is discharged, through the emission outlets (21, 23, 25) , to outside the casing (10) .
  • Air emitted downward from the second fan (55) is guided by the guide plate (49) , flows along the second flow path (27b) defined between the flow path separating plate (48) and the partitioning plate (41) , and is discharged, through the emission outlets (21, 23, 25) , to outside the casing (10) .
  • air blown out of the first fan (51) and air blown out of the second fan (55) flow along different flow paths (i.e., the flow paths (27a, 27b)) without interfering with each other and are exhausted to outside the casing (10) .
  • the two fans (51, 55) are disposed vertically one above the other, thereby making it possible to increase the volume of emission of air without expanding the area required for installing an air conditioner outdoor unit.
  • the provision of the separator plate (46) allows air emitted downward from the first fan (51) to smoothly flow between the separator plate (46) and the back plate (11) of the casing (10) and to smoothly flow upward. This increases the volume of emission of air from the first fan (51) .
  • the first flow path (27a) along which air blown out of the first fan (51) flows upward and the second flow path (27b) along which air blown out of the second fan (55) flows are separated by the flow path separating plate (48) , whereby the air blown out of the first fan (51) and the air blown out of the second fan (55) flow smoothly without interfering with each other.
  • This increases the volume of air that is emitted from each fan (51, 55) .
  • the provision of the side emission outlet (23) of the side part (15) may be omitted.
  • the provision of the first and second side emission outlets (23, 25) of the side parts (15) may be omitted.
  • the fan motor (53) is not necessarily required to be secured, via the motor stand (54) , to the tube plates (34, 35) of the heat exchanger (30) .
  • it may be arranged such that a supporting column is standingly provided on a bottom plate on the rear surface side of the heat exchanger (30) and the fan motor (53) is secured to the supporting column.
  • the fan (51) is implemented by a mixed flow fan.
  • the fan (51) may be implemented by for example an axial fan.
  • the provision of the separator plate (46) may be omitted.
  • the present invention provides air conditioner outdoor units useful for so-called separate type air conditioners, particularly suitable for the case where the volume of emission of air from an outdoor unit is increased.
