Abstract:
1. A window air conditioner for mounting at an existing window frame, comprising: an indoor housing; an outdoor housing; an air conditioning unit comprising a first means for removing heat from indoors at said indoor housing, a second means for releasing said heat to outdoors at said outdoor housing, and a power control panel provided at said indoor housing to control said first and second means, wherein said first means comprises an evaporator coil, an evaporator fan, and a condensate remover pump, wherein said second means comprises a condenser coil, a condenser fan, and a compressor; a single connecting rod having a hollow structure extended between said indoor housing and said outdoor housing, wherein said connecting rod has a predetermined size substantially smaller than a width of each of said indoor housing and outdoor housing; wherein said connecting rod serves as a bridge for suspendedly hanging said air conditioning unit at said window frame at a position that said indoor housing is supported at an interior side of said window frame while said outdoor housing is supported at an exterior side of said window frame, wherein said hollow structure forms a channel that said first means is operatively connected to said second means through said channel of said connecting rod, wherein two ends of said connecting rod are secured to metal sides of said indoor and outdoor housings respectively at a point to keep the balance between that said indoor and outdoor housings, wherein said connecting rod also forms means for carrying said indoor and outdoor housings; a capillary tube, a power line, a suction line, and a condensate line running through said connecting rod to operatively couple said first means in said outdoor housing with said second means at said indoor housing; and an insulation wrapping around said suction line and said capillary tube within said connecting rod to prevent absorption of heat, wherein said first means further comprises a water pump controlled by a water level controlling switch and arranged in such a manner that when water reaches a certain level, said water pump is activated to pump said water in said indoor housing to said outdoor housing through said condensate line; wherein said window air conditioner is adapted for being installed into said existing window frame with either horizontal sliding window or vertical sliding window to minimize a gap with respect to the size of said connecting rod, wherein said gap formed by sliding said horizontal sliding window to close said existing window frame is about the same as said gap formed by sliding said vertical sliding window to close said existing window frame; whereby a user is capable of mounting said air conditioning unit through the use of said connecting rod without substantially and structurally modifying said existing window frame; whereby, said window air conditioner is adapted for being installed into said existing window frame with horizontal sliding window by positioning said connecting rod at the furthest end of end of said horizontal sliding window such that there is a gap about the width of said connecting rod when said horizontal sliding window is slid to close, so as to minimize the gap with respect to the size of said connecting rod; whereby, said window air conditioner is adapted for being installed into said existing window frame with vertical sliding window by positioning said connecting rod at a sill of said window frame, such that there is a gap about the height of said connecting rod when said vertical sliding window is slid to close, so as to minimize the gap with respect to the size of said connecting rod.
