Referring to fig. 3 and 4, in the example of the present invention, in order to prevent wash water in the outer tub 10 from entering the circulation fan 50 during the washing process and causing damage to the circulation fan 50 due to water immersion, a non-return valve 90 is disposed on a pipe (i.e., on the first extension air duct 31) where the circulation fan 50 communicates with the mounting portion 11, such that in the washing state, the non-return valve 90 is in a closed state to block a passage between the mounting portion 11 and the circulation fan 50, and in the drying state, the non-return valve 90 is in an open state under the action of wind force of the circulation fan 50, thereby achieving communication between the circulation fan 50 and the mounting portion 11.

Referring to fig. 4, in the present example, the check valve 90 includes a rotating shaft 91, a sealing member 92 and a limiting member 93, the sealing member 92 is pivotable about the rotating shaft 91, the sealing member 92 and the limiting member 93 cooperate to close the passage when in the washing state, and the sealing member 91 is blown up by the circulating fan 50 to achieve the circulation wind conduction when in the drying state.

As shown in fig. 2, in order to facilitate the arrangement of the air duct and reduce the influence of the arrangement of the extended air duct on the assembly between the annular air duct 30 and the outer tub 10, the air outlet 35 may be disposed on the inner peripheral side wall of the annular air duct 30, and the air inlet 34 may be disposed on the outer peripheral side wall of the annular air duct 30.

As shown in fig. 1 and 2, according to a further example of the present invention, a third extending air channel 33 is provided at the air outlet 35, and the third extending air channel 33 extends obliquely toward the direction of the clothes inlet, so that the wet air in the inner tub 20 can be sucked into the annular air channel 30 more quickly through the third extending air channel 33, thereby promoting the formation of negative pressure in the inner tub 20, ensuring air circulation and improving drying efficiency.

According to an embodiment of the present invention, in order to improve the heat exchange efficiency and accelerate the condensation and dehumidification of the gas in the annular air duct 30, the annular air duct 30 and the condenser 40 are in surface contact with each other, so that the heat exchange between the two can be performed through a direct contact surface.

In one example of the present invention, the condenser 40 is formed as an annular condensing channel, and the annular condensing channel is attached to the front side of the annular discharge port, and a condensing medium (for example, cooling water) enters through the inlet end 41 of the annular condensing channel, and exchanges heat with the damp-heat gas in the annular air duct 30 in the condensing channel, so that the damp-heat gas is dehumidified after being condensed, and then flows out through the outlet end 42 of the annular condensing channel, and the heat exchange is realized by continuously feeding the cooling medium. In another example of the present invention, an annular installation groove adapted to accommodate the annular condenser 40 is formed in the front side of the annular air duct 30, and the annular condenser 40 is installed in the annular installation groove to contact with a plurality of surfaces of the annular air duct 30, so that the heat exchange effect is further enhanced, and the installation of the annular condenser 40 in the annular installation groove can simplify the assembly therebetween, and further save space.
