  • Patent number: 11982462
    Abstract: An air conditioner includes a cabinet including an inlet port and a frame including an outlet port and coupled to the cabinet. A heat exchanger is disposed between the cabinet and the frame to exchange heat with air introduced into the inlet port and discharged to the outlet port. A blocking member is configured to connect the frame and the heat exchanger to prevent air heat-exchanged with the heat exchanger from leaking into the cabinet. This structure inhibits dew from being generated on the cabinet.
