The invention provides a portable air conditioner suitable for various occasions, which comprises an indoor unit and an outdoor unit, wherein the indoor unit and the outdoor unit are connected with each other via an indoor and outdoor connecting
assembly;
fast switching of the indoor and outdoor connecting
assembly is realized via a fast connecting component; the indoor unit comprises an automatic drainage
system which is characterized in that a
water level induction passage is formed on the inner side surface of a clamping groove formed in one end of an indoor unit water-containing plate; an
electromagnetic induction switch is in
interference fit with an
electromagnetic induction switch clamping groove; a floating ball is limited in the
water level induction passage; an indoor unit drainage
pipe is connected to the water-containing plate; an outdoor unit drainage
pipe is connected to an outdoor unit water pump; after the indoor unit drainage
pipe and an outdoor unit connecting
water pipe are butted via the fast connecting component, an automatic drainage passage is formed; both the
electromagnetic induction switch and the water pump communicate with a controller; and the controller controls the on / off of the water pump according to
water level information of the electromagnetic induction switch. Due to the automatic drainage
system, the portable air conditioner can run continuously to ensure the comfort of a user; and moreover, as manual drainage is avoided, the portable air conditioner is convenient and practical for the user.
