Definitions

  • the present invention relates to an air-conditioning indoor machine, and particularly relates to a wall-mounted air-conditioning indoor machine.
  • an air-conditioning indoor machines of air conditioners that are installed not in the ceiling but in the side wall of a room, that draw in air from the front surface or top surface, and that blow conditioned air out from a blow-out port in the bottom, have been quite common in the past.
  • the interior of an indoor machine accommodates a heat exchanger for conducting heat exchange between a refrigerant and air, and/or a cross-flow fan.
  • an air-conditioning indoor machine has a stabilizer and a rear guider as members configuring an air distribution passage, as is disclosed in Patent Literature 1 (Japanese Laid-open Patent Application No. 2008-8500 ).
  • EP 1 243 864 A2 discloses a wall-mounted air-conditioning indoor machine according to the preamble of claim 1, and US 2002/172588 A1 discloses an air conditioner.
  • An object of the present invention is to provide an air-conditioning indoor machine having both surging proof stress and the property of energy conservation.
  • An air-conditioning indoor machine is a wall-mounted air-conditioning indoor machine, comprising a cross-flow fan, a casing, and a heat exchanger.
  • the cross-flow fan has a plurality of blades aligned along the circumference, and generates an air flow.
  • the casing includes a stabilizer on the front-surface side, and a rear guider on the back-surface side.
  • a blown air channel for air flowing in a scroll-like manner from the cross-flow fan to a blow-out port is formed in the casing by the stabilizer and the rear guider.
  • the stabilizer is divided into a top part and a bottom part with a tongue part in between.
  • the heat exchanger includes a front-surface-side heat exchange section and a back-surface-side heat exchange section, and the heat exchanger is arranged on the airflow-upstream side of the cross-flow fan.
  • a horizontal line through a fan center point which is the rotational center of the cross-flow fan, is a fan-referencing horizontal line.
  • a line designated as a scroll-referencing line is a straight line that, of any straight line tangent to a circle connecting the outer ends of the fan blades of the cross-flow fan and adjoining the bottom part of the stabilizer, forms the smallest angle with the fan-referencing horizontal line.
  • an angle designated as a first angle ⁇ a is the angle formed by the fan-referencing horizontal line and a first straight line, which is a straight line connecting the fan center point and a front-surface-side closest point which is the point on the top part of the stabilizer that is closest to the cross-flow fan.
  • an angle designated as a second angle ⁇ b is the angle formed by the fan-referencing horizontal line and a second straight line, which is a straight line connecting the fan center point and a back-surface-side closest point which is the point on the rear guider that is closest to the cross-flow fan.

  • the height position of the front-surface-side closest point of the stabilizer is thereby kept low, whereby the air flow from the lower part of the front-surface-side heat exchange section to the cross-flow fan is not so greatly inhibited, and the so-called fan intake angle can be increased within a range of no more than 180°. Therefore, an air flow with little loss is produced, and less of the air flow from the cross-flow fan to the blow-out port flows backward to the intake port.

  • the lower part of the front-surface-side heat exchange section is arranged in a low position so that the fourth angle relational expression is satisfied
  • the lower part of the back-surface-side heat exchange section is arranged in a low position so that the fifth angle relational expression is satisfied, and the capacity of the heat exchanger can be increased.
  • the flow of air from the lower part(s) of the front-surface-side heat exchange section and/or the back-surface-side heat exchange section to the cross-flow fan is not readily inhibited even if either lower part is arranged in a low position, air flows in large quantities to the lower parts of both heat exchange sections, and the property of energy conservation is improved.
  • the capacity of the heat exchanger is increased, but more air flows to the lower parts of the heat-exchanging parts, and energy conservation is further improved.

  • the "fan intake angle" (the angle on the intake port 10a side formed by the first straight line SL1 and the second straight line SL2) can be increased within a range of no more than 180°.
  • the flow of air from the cross-flow fan 30 toward the blow-out port 10b is hindered from flowing back to the intake port 10a.
  • surging proof stress is improved in the air-conditioning indoor machine 92.
  • Past air-conditioning indoor machines often have a fan intake angle of about 170°.
  • the height position of the back-surface-side closest point P8 of the rear guider 18 is kept to an appropriate range, thereby suppressing the increase in fan power caused by the rear guider 18 being too low, and improving the property of energy conservation.
  • FIG. 5 shows data to be a base of the second angle relational expression.
  • the horizontal axis represents the angle difference ( ⁇ b - ⁇ 0), and the vertical axis represents the same efficiency improvement amount as FIG. 4 .
  • the efficiency improvement amount is small when the angle difference ( ⁇ b - ⁇ 0) is less than 17° or greater than 26°, and the efficiency improvement amount is large when the angle difference is within a range of 17° to 26°.
  • the angle difference ( ⁇ b - ⁇ 0) is either 18°, 22°, or 25°, the efficiency improvement amount is large and the increase in fan power is suppressed.
  • the lower part 21a of the front-surface-side heat exchange section 21 is arranged in a low position so that the fourth angle relational expression is satisfied, and the lower part 22a of the back-surface-side heat exchange section 22 is arranged in a low position so that the fifth angle relational expression is satisfied; therefore, the capacity of the heat exchanger 20 increases.
  • a greater capacity of the heat exchanger 20 than those in the past is ensured because the third angle ⁇ c is at least 45° and the air-conditioning indoor machine 92 employs a structure in which the lower part 21a of the front-surface-side heat exchange section 21 is extended downward.
  • the air-conditioning indoor machine 92 When the air-conditioning indoor machine is equipped with this large heat exchanger 20, the distribution of the air flow through the heat exchanger is partially imbalanced, the air flow is inhibited, and fan power tends to be high, but because the air-conditioning indoor machine 92 employs a component arrangement that satisfies the first angle relational expression, the second angle relational expression, and the third angle relational expression all together as described above, the air flow from the lower parts 21a, 22a of the heat exchanger 20 to the cross-flow fan 30 is not readily inhibited, and air flows in large quantities to the lower parts 21a, 22a of the heat exchange sections 21, 22 as well. In other words, the property of energy conservation of the air-conditioning indoor machine 92 is improved.
  • the air-conditioning indoor machine 92 employs a structure in which indoor air is drawn in through the intake port 10a formed in the ceiling of the casing 10, which is in a higher position than the fan center point O, and also employs a structure in which the lower part 21a of the front-surface-side heat exchange section 21 and the lower part 40a of the filter 40 are both positioned lower than the fan center point O. Therefore, when past design methods are followed, less air passes through the lower part 21a of the front-surface-side heat exchange section 21, and the entire heat exchanger 20 can no longer be effectively utilized.
  • the lower part 40a of the filter 40 is first extended downward to a lower position than in the past so as to satisfy the first expression described above, and a channel is ensured for air to flow through the lower part 40a of the filter 40 toward the lower part 21a of the front-surface-side heat exchange section 21.
  • the cross-flow fan 30, the heat exchanger 20, the filter 40, and the front surface panel 15 are arranged so that the three gap distances D1, D2, and D3 satisfy the second expression described above, and while the depth dimension of the air-conditioning indoor machine 92 is kept small, there is little pressure loss in the channel for air flowing through the gap between the filter 40 and the front surface panel 15 (of which the gap distance is the third distance D3), from the intake port 10a to the lower part 40a of the filter 40 and the lower part 21a of the front-surface-side heat exchange section 21. A sufficient quantity of air passing through the lower part 21a of the front-surface-side heat exchange section 21 is thereby ensured, and a structure is achieved in which the entire heat exchanger 20 is effectively utilized.
  • the air-conditioning indoor machine 92 employs a component arrangement that satisfies the second expression in order to keep the depth dimension (the dimension in the left-right direction in FIG. 2 ) small, but when the first distance D1 is too small, the front-surface-side heat exchange section 21 and the cross-flow fan 30 are too close together, and there may be sounds when air passes through the front-surface-side heat exchange section 21.
  • the air-conditioning indoor machine 92 employs a component arrangement that satisfies the third expression described above.
  • the first distance D1 which is the gap distance between the cross-flow fan 30 and the front-surface-side heat exchange section 21 at the same height position as the fan center point O, is made to be greater than 30% of the fan radius R, whereby the sounds are kept to an allowable range. If this size is ensured for the first distance D1 of the air-conditioning indoor machine 92, the air flow that has passed through the heat exchanger 20 can be changed to a non-periodic wide-range turbulent flow structure and then made to collide with the fan blades 31, and the periodic sounds caused by the interaction with the fan blades 31 can be reduced.
  • the front surface panel 15 is arranged so as to satisfy the fourth expression described above, and the distance from the fan center point O to the front surface panel 15 (the fourth distance D4) is comparatively small.
  • a thin air-conditioning indoor machine 92 with a minimized depth dimension is thereby achieved, but because a structure is employed which simultaneously satisfies the first through third expressions, the entire heat exchanger 20 can be effectively utilized even if the machine has a thin profile.
