Patent number: 11982462Abstract: 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.Type: GrantFiled: October 8, 2019Date of Patent: May 14, 2024Assignee: SAMSUNG ELECTRONICS CO., LTD.Inventors: Chang-Woo Jung, Sung Jae Kim, Jin-Gyun Kim, Young Tae Song, Hae Gyun Shin, Chang Sik Lee, Seo Young Cho, Sung Hyun Chun
