Technical Field

[0001] The present invention relates to the technical field of washing machines, in particular to a double-layer condenser, and also to a washer-dryer comprising the double-layer condenser. Background Art

[0002] Existing washer-dryers mainly use water-cooling for drying. How to quickly exchange the hot steam in the inner drum will directly affect the performance of the washer-dryer.

[0003] In order to improve the condensation effect, two methods are usually adopted: increasing the heat exchange surface and increasing the cooling water. Increasing the heat exchange surface will increase the volume of the device, and increasing the cooling water will increase the water consumption.

[0004] The condensers of existing washer-dryers are generally injection molded or blow molded. The dryer absorbs hot steam from the barrel into the condensing cylinder and injects cooling water from the water inlet. The cooling water flows directly along the side wall of the condenser. The heat exchange between the cooling water and the hot steam depends entirely on the amount of water injected and the residence time on a single side wall of the condensing cylinder. Most of the cooling water is wasted.

[0005] Therefore, how to improve the heat exchange effect of the condenser is a technical problem that technicians in this field currently need to solve. Summary of the invention

The height of the first water diversion rib is flush with the heat exchange plate. After the cooling water passes through the water diversion cavity, a part of it flows into the first cooling channel, and the other part flows into the second cooling channel under the blocking effect of the first water diversion rib.

[0014] Preferably, a plurality of second water-dividing ribs arranged at intervals are provided on the second side of the water-dividing cavity, and the first side and the second side of the water-dividing cavity are adjacent to each other.
