The application discloses a middle partition plate of an air conditioner, the air conditioner comprising an
evaporator and a condenser, the middle partition plate being used for receiving
condensed water generated by the
evaporator, the middle partition plate being arranged above the condenser, and the middle partition plate comprising: a disc body, the disc body being provided with a water receiving area for receiving the
condensed water generated by the
evaporator, a plurality of water outlets being further arranged on the disc body, the
condensed water flowing to the condenser through the water outlets, a ring-shaped surrounding plate being further arranged on the disc body to define an overflow channel, and an overflow hole being arranged on the disc body and being in communication with the overflow channel; and an opening and closing member, the opening and closing member being movably arranged on the disc body, and the opening and closing member being configured to open the overflow hole when the amount of the condensed water in the overflow channel meets a set condition. Thus, the problem of
mutual influence of the upper and lower air fans can be solved by the conditional opening of the overflow hole by the opening and closing member, the risks of stall, surge, abnormal sound and the like of the air fan can be avoided, and the user experience can be improved.
