  • Patent number: 7930897
    Abstract: A window type air conditioner comprises: a case of which one side is positioned indoors and another side is positioned outdoors; an axial fan mounted in the case for blowing the air in the radius direction thereof; a shroud having the axial fan therein and for guiding the air blown by the axial fan; and an orifice formed at the entrance of the shroud and covering the axial fan not to expose the axial fan to outside in order to prevent sucked air from colliding with the blade of the axial fan in the radius direction. According to this, the entire size of the air conditioner is minimized, noise is reduced, and the air volume passing through the outdoor heat exchanger is increased.

  • Patent number: 7454921
    Abstract: A window type air conditioner comprises: a case having an indoor air suction port for sucking indoor air and an indoor air discharge port for discharging heat-exchanged air indoors; an indoor unit mounted inside the case positioned at an indoor side thus to be heat-exchanged with indoor air, and an outdoor unit mounted inside the case positioned at an outdoor side thus to be heat-exchanged with outdoor air, in which the indoor air suction port is formed at a front surface of the case and the indoor air discharge port is formed at an inclination front surface between the front surface and an upper surface of the case. According to this, indoor air smoothly flows thus to increase an air discharge amount, and a flow resistance is decreased thus to reduce noise.

  • Publication number: 20070056305
    Abstract: A window type air conditioner comprises: an indoor unit mounted inside a case positioned at the indoor side thus to be heat-exchanged with the indoor air; an outdoor heat exchanger mounted inside a case positioned at the outdoor side thus to be heat-exchanged with the outdoor air; and an outdoor cross flow fan for generating a blowing force so that the out-door air can pass through the outdoor heat exchanger and for sucking the outdoor air in a circumferential direction thereof and thereby discharging the outdoor air in the circumferential direction thereof. According to this, noise is lowered, the air volume lowering due to a channel resistance is prevented, and the entire size of the air conditioner is minimized.
