A unit-type air conditioner has an out-door portion which has an out-door heat-exchanger, an out-door fan opposing the out-door heat exchanger and an air guider having an orifice defining the passage of air from the out-door fan and the out-door heat exchanger. The center of the circle of a slinger ring attached to the out-door fan is slightly offset from the center of the circle of the orifice such that the circle of the slinger ring is offset from the center of the orifice in the direction in which the slinger ring scoops condensate water generated in the air conditioner. Part of the condensate water scooped by the slinger ring is sprayed to the out-door heat exchanger so as to be evaporated by the heat generated in the heat-exchanger, while the remaining part of the condensate water collides with the wall of the orifice so as to be returned to a drain pan. Consequently, undesirable springing of condensate wall from out-door air suction openings is avoided.

Condensate water disposal arrangement for unit-type air conditioner

A control box 6 of an air conditioner at the front part of the body has two compartments 6A, 6B parted by a partition plate 7. One compartment 6A is for receiving lead wires 2 which connect electric components with a compressor motor and a fan motor, and the other compartment 6B is for containing electric parts. The lead wires 2 are folded once in the compartment 6A. and again folded at the rear end of the partition plate 7. By such twice folding of the lead wires and cramping them at the rear end of the partition plate 7, damaging of electric components by the lead wires is prevented.

Integral type air conditioner

An L-shaped one-package type air conditioner comprising an air circuit unit which extends horizontally to be positioned indoors, and an outdoor unit which extends downwardly from the rear end portion of the air circuit unit is provided with an elongate member protruding downwardly from the lower surface of the air circuit unit, and with two projections. A bracket for installing the air conditioner is also disclosed. The bracket comprises: a fixing portion which engages with a window frame; an upper guiding portion extending horizontally; and a lower guiding portion extending vertically. The projections are guided by the upper and lower guiding portions.

A wind direction deflection blade mounting apparatus for use in a unitary air conditioner having an outer box, a substrate removably housed in the outer box, and a partition board which partitions said unitary air conditioner into an outdoor side and an internal side in which the outdoor side is provided with a compressor, a fan motor, an outdoor heat exchanger, and an indoor fan and said indoor side is provided with an indoor heat exchanger, an inlet port, and outlet port, and a foam including an indoor fan, which comprises a plurality of wind deflection blades, a coupling means for being rotatably coupled with said interlocking shafts of said blades, a motor housing chamber, a removable drive unit having a motor for reciprocating said coupling means housed in said motor housing chamber, a crankshaft extending from the shaft of said motor and a shaft inserting groove provided on the bottom face of said outlet port and opening in the front face thereof and extending toward the rear face of said outlet port thereby to render to easily assemble wind direction deflection blades mounted on an outlet port to make a pivotal motion.

Wind direction deflection blade mounting apparatus

A self-contained air-conditioning unit which includes an outer box, a base plate slidably removably inserted in the outer box, and a bulkhead on the base plate partitioning the interior of the outer box into an indoor portion and an outdoor portion. A compressor and a condenser are provided adjacent a rear face of the outer box. In the outdoor portion are provided a compresser, and a condenser adjacent the rear face of the outer box. The condenser includes a central portion and left and right curved ends. An evaporator and an indoor fan are provided in the indoor portion. A fan motor drives the indoor fan and an outdoor fan which faces the central portion of the condenser. Air inlets having louvers are provided in the outer box adjacent the curved ends of the condenser. Blow-off ports are provided in the outer box between the outdoor fan and the bulkhead. A slinger ring is disposed on the outdoor fan to scatter condensed water on the base plate. Air inlet ports are also provided on the rear face of the outer box so as to oppose the central portion of the condenser. The outdoor fan is located so as to draw air through the inlet and the condenser to the blow-off ports such that some of the condensed water scattered by the slinger ring directly hits the condenser so as to be evaporated by the air drawn therethrough and some of the scattered water is directly carried by the air drawn through the condenser to the blow-off ports.
