Samsung patents window AC with stretchy hose to fit any frame

Samsung has been granted a patent for a window air conditioner that uses a spiral-shaped coolant pipe and a bellows-style cover to connect the indoor and outdoor units. This design allows the distance between the two parts to expand or compress, enabling the unit to fit window frames of varying thicknesses without needing custom parts.

Why it mattersThis design simplifies installation by allowing a single unit size to accommodate different window depths, which is a practical improvement for homeowners installing window ACs.

In the filing’s own words

A window-type air-conditioner installable on a window frame, and including an outdoor module including a compressor to compress a coolant, an outdoor heat exchanger to generate heat exchange between outdoor air and the coolant, and an outdoor housing accommodating the compressor and the outdoor heat exchanger; an indoor module including an indoor heat exchanger to generate heat exchange between indoor air and the coolant, and an indoor housing spaced apart from the outdoor housing, and accommodating the indoor heat exchanger; a coolant pipe along which the coolant moves between the outdoor and indoor modules; and a pipe cover accommodating the coolant pipe, and connecting the indoor and outdoor modules. The coolant pipe has a spiral shape that is expandable and compressible, and the pipe cover structure is expandable and compressible, to adjust an interval between the outdoor and indoor modules to correspond to a thickness of the window frame.

What exactly they claim (claim 1)

1. A window-type air-conditioner installable on a window frame, the window-type air-conditioner comprising: an outdoor module including: a compressor configured to compress a coolant, an outdoor heat exchanger configured to generate heat exchange between outdoor air and the coolant, and an outdoor housing accommodating the compressor and the outdoor heat exchanger; an indoor module including: an indoor heat exchanger configured to generate heat exchange between indoor air and the coolant, and an indoor housing spaced apart from the outdoor housing, and accommodating the indoor heat exchanger; a coolant pipe providing a flow path along which the coolant moves between the outdoor module and the indoor module; a pipe cover accommodating the coolant pipe, and connecting the indoor module and the outdoor module; a sealing member coupled to the pipe cover, and configured to provide a seal between an outer circumferential surface of the pipe cover and the window frame on a plane perpendicular to a direction in which the pipe cover extends, wherein the coolant pipe has a spiral shape that is expandable and compressible, and the pipe cover has a structure that is expandable and compressible, to adjust an interval between the outdoor module and the indoor module so that the interval corresponds to a thickness of the window frame, the structure of the pipe cover is a bellows structure including a plurality of corrugations, and the sealing member includes a coupling surface in contact with the outer circumferential surface of the pipe cover, the coupling surface including an uneven portion corresponding to the plurality of corrugations of the pipe cover.
