The water inlet is provided with a flow dividing device, but condensed water cannot be prevented from splashing into the rear wall of the inner cylinder to wet clothes under the condition that the water inlet pressure is unstable.

3. The novel baffle is provided with the profiling part to ensure that the baffle is fully distributed with the largest area of condensed water to realize the condensation of the largest area, thereby better realizing the heat exchange between the hot air at the air outlet position and the baffle. The novel baffle not only serves as a second condensing part which exchanges heat with hot and humid air, but also serves as a baffle at the position of a condensed water inlet to ensure the stability of the condensed water inlet position. The condensed water passing through the baffle stably flows into a second condensing part (smooth transition of the tail end of the baffle) formed by the guide ribs. And the splash can not be generated due to unstable water inflow under the condition of unstable water pressure. Therefore, the splash defect of the guide rib in the prior art caused by unstable water pressure is overcome.
