Definitions

  • the present invention relates to an airflow control method and airflow controller for an air conditioner indoor unit to execute indoor air conditioning.
  • an air conditioner indoor unit that includes a cross-fin heat exchanger and a cross-flow fan provided inside a roughly rectangle-shaped casing mounted on a wall surface and blows conditioning air from an outlet port provided in the lower portion of the casing.
  • the blowoff wind direction of the conditioning air of an indoor unit 80 mounted on the wall surface is almost limited to one direction. Therefore, the human being tends to feel a sense of airflow in a living space S1 during heating operation or particularly at the time of starting the heating operation. Furthermore, a uniform temperature distribution cannot be obtained unless a flap for controlling the blowoff wind direction is operated to swing, and this leads to a problem of comfort.
  • the object of the present invention is to provide an airflow control method and airflow controller for an air conditioner indoor unit capable of executing air conditioning so that the indoor temperature distribution becomes uniform with no flap swing function without causing a sense of airflow during heating operation.
  • the present invention provides an airflow control method for an air conditioner indoor unit including a casing, a turbofan that has an axis extending in an anteroposterior direction and blows air taken in from a front surface side radially outwardly with respect to an axis inside the casing, a heat exchanger disposed on the front surface side of the turbofan inside the casing, outlet ports that are provided for the casing and blow air from the turbofan in a vertical direction and a horizontal direction and flaps for controlling wind directions of the blowoff air from the respective outlet ports, wherein, openings of upper, right-hand and left-hand flaps are narrowed and opening of a lower flap is made wider than the openings of the upper, right-hand and left-hand flaps during heating operation.
  • the blowoff air flows and circulates so as to cover the indoor living space along the wall surface, ceiling surface and floor surface by virtue of the four-direction blowoff. Then, by narrowing the openings of the upper flap, right-hand flap and left-hand flap and making the opening of lower flap wider than the openings of the above flaps during heating operation, the blowoff air volume from the outlet ports located on the upper side, right-hand side and left-hand side is reduced to consequently increase the air volume from the outlet port located on the lower side. This allows the indoor air to circulate and further allows warm air to reach the level of feet.
  • air conditioning can be achieved so that the indoor temperature distribution becomes uniform with no flap swing function without causing a sense of airflow during the heating operation.
  • the total volume of blowoff air from the upper, lower, right-hand and left-hand outlet ports at the time of starting the heating operation at a low temperature in the living space scarcely changes, and therefore, the indoor heating can be immediately achieved without reducing the heating capacity.
  • the present invention also provides an airflow controller for an air conditioner indoor unit including a casing, a turbofan that has an axis extending in an anteroposterior direction and blows air taken in from a front surface side radially outwardly with respect to an axis inside the casing, a heat exchanger disposed on the front surface side of the turbofan inside the casing, outlet ports that are provided for the casing and blow air from the turbofan in a vertical direction and a horizontal direction and flaps for controlling wind directions of the blowoff air from the respective outlet ports, the controller comprising:
  • the blowoff air flows and circulates so as to cover the indoor living space along the wall surface, ceiling surface and floor surface by virtue of the four-direction blowoff. Then, by narrowing the openings of the upper flap, right-hand flap and left-hand flap and making the opening of lower flap wider than the openings of the above flaps with the control signal outputted to the drive section by the flap control section during heating operation, the blowoff air volume from the outlet ports located on the upper side, right-hand side and left-hand side is reduced to consequently increase the air volume from the outlet port located on the lower side. This allows the indoor air to circulate and further allows warm air to reach the level of feet.
  • air conditioning can be achieved so that the indoor temperature distribution becomes uniform with no flap swing function without causing a sense of airflow during the heating operation.
  • the total volume of blowoff air from the upper, lower, right-hand and left-hand outlet ports at the time of starting the heating operation at a low temperature in the living space scarcely changes, and therefore, the indoor heating can be immediately achieved without reducing the heating capacity.
  • Fig. 1 is an exploded perspective view of the essential part of an indoor unit that uses the airflow control method for the air conditioner indoor unit according to one embodiment of the present invention and includes a roughly square-shaped bottom frame 1 fastened to an indoor wall surface on its rear surface side, a motor 2 fastened via a motor clamping plate 12 to a mounting section 11 provided roughly at the center of the bottom frame 1, a turbofan 3 whose axis is arranged in the anteroposterior direction with respect to the bottom frame 1 and driven by the motor 2 to blow air taken in from the front surface side radially outwardly with respect to the axis, a bellmouth 4 fastened to the bottom frame 1 on the front surface side of the turbofan 3, a heat exchanger 5 fastened on the front surface side of the bellmouth 4, a front panel 6 that is fastened to the bottom frame 1 on the front surface side of the heat exchanger 5 and has a roughly square-shaped inlet port 6a and an inlet grill 7 that is fastened to the inlet port 6a of the front panel 6 and is

  • the controller 10 is constructed of a microcomputer, an input/output circuit and so on and includes a flap control section 10a for controlling the openings of the upper flap 31, lower flap 32, right-hand flap 33 and left-hand flap 34 by outputting a control signal to the stepping motors 41 through 44 according to the state of operation.
  • the stepping motors 41 through 44 and the flap control section 10a of the controller 10 constitute an airflow controller.
  • Figs. 5 and 6 are sectional views of the essential part of the outlet port located on the upper side of the air conditioner indoor unit and the essential part of the outlet ports located on the lower side, right-hand side and left-hand side of the air conditioner indoor unit. It is to be noted that Figs. 5 and 6 are provided for explaining the detail of the air conditioner outlet port structure and are different from the outlet port structure of the indoor unit shown in Fig. 3.
  • a guide section 51 having a curved surface 51a that is gradually curved forwardly diagonally from the turbofan 3 side is arranged on the rear surface side of an outlet port 53 located on the upper side of a casing 50.
  • a guide section 52 having a curved surface 52a that is gradually curved forwardly diagonally from the turbofan 3 side is arranged on the front surface side of the outlet port 53.
  • the upper flap 54 has its front edge side curved toward the turbofan 3 side so that air smoothly flows along the blowoff path in a state in which the flap is opened with a specified opening.
  • a plurality of vertical plates 56 (only one is shown in Fig. 5) extending roughly perpendicularly at regular intervals are provided on the front surface side of the wing surface of the upper flap 54. Airflow control of air blown from the turbofan 3 is executed so that the wind direction comes to have an angle of approximately 60 degrees with respect to the plane perpendicular to the axis of the turbofan 3 forwardly diagonally upward by the guide sections 51 and 52 and the upper flap 54 when the upper flap 54 is opened with a specified opening. In order to narrow the opening of the upper flap 54, the upper flap 54 is pivoted in the direction of the arrow R3.
  • a guide section 61 having a curved surface 61a that is gradually curved forwardly diagonally from the turbofan 3 side is arranged on the rear surface side of the outlet ports 63 located on the lower side, right-hand side and left-hand side of the casing 50.
  • a guide section 62 having a curved surface 62a that is gradually curved forwardly diagonally from the turbofan 3 side is arranged on the front surface side of the outlet ports 63.
