The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0045] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0046] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0047] Existing multi-drum washing machines have a small airflow area at the drum outlet during multi-drum washing and drying. After the drying airflow inside the drum exchanges heat with the clothes, it cannot be discharged in time, resulting in untimely replenishment of the drying airflow inside the drum, long drying time, and low drying efficiency.

[0048] like Figures 1 to 3 As shown, the present invention creatively provides a clothing processing device with a drying function, comprising:

[0049] The roller includes an upper roller 11 and a lower roller 12 arranged opposite each other. The upper roller 11 has M upper air inlets and N upper air outlets, and the lower roller 12 has M lower air inlets and N lower air outlets.

[0050] An air intake device includes M air intake and distribution components and 2M air intake ducts; each air intake and distribution component forms an air intake and distribution cavity, a main air intake and distribution cavity inlet communicating with the air intake and distribution cavity, an upper air intake and distribution cavity branch inlet, and a lower air intake and distribution cavity branch inlet; the upper air intake and distribution cavity branch inlet and the lower air intake and distribution cavity branch inlet can be controlled to open or close; the M upper air intakes and the M upper air intake and distribution cavity branch inlets are arranged one-to-one and connected by the M air intake ducts; the M lower air intakes and the M lower air intake and distribution cavity branch inlets are arranged one-to-one and connected by the other M air intake ducts;

[0051] An air outlet device includes N air outlet and distribution components and 2N air outlet ducts; each air outlet and distribution component forms an air outlet and distribution cavity, an upper branch port of the air outlet and distribution cavity, a lower branch port of the air outlet and distribution cavity, and a main outlet port of the air outlet and distribution cavity, which are connected to the air outlet and distribution cavity. The upper branch port and the lower branch port of the air outlet and distribution cavity can be controlled to open or close; the N upper air outlets and the N upper branch ports of the air outlet and distribution cavity are arranged one-to-one and connected to the N air outlet ducts; the N lower air outlets and the N lower branch ports of the air outlet and distribution cavity are arranged one-to-one and connected to the other N air outlet ducts.

[0053] Where M and N are both positive integers and M≥1, N≥1;

[0054] The drying airflow in the upper drum 11 can enter the fan chamber through multiple upper air outlets and corresponding air distribution chambers. The drying airflow in the fan chamber flows sequentially through the two chambers, the air distribution chamber, and the air inlet duct before re-entering the upper drum 11, thus timely refreshing the drying airflow in the upper drum 11. Similarly, the drying airflow in the lower drum 12 can enter the fan chamber through multiple lower air outlets and corresponding air distribution chambers. The drying airflow in the fan chamber flows sequentially through the two chambers, the air distribution chamber, and the air inlet duct before re-entering the lower drum 12, thus timely refreshing the drying airflow in the lower drum 12. This improves the refresh rate of the drying airflow, enhances the heat exchange between the drying airflow and the clothes inside the drum, shortens the drying time, and improves drying efficiency.

[0055] Based on the moisture content of the clothes in the upper drum 11, the moisture content of the clothes in the lower drum 12, the temperature of the drying airflow, and the temperature of the drying airflow, the opening or closing of the M upper inlet and lower outlet ports of the air inlet and outlet can be coordinated to make the drying airflow flow in the upper drum 11, the lower drum 12, the two-component assembly 62, and the fan 61, thereby improving the drying efficiency.

[0056] Furthermore, M = 1 and N = 2; or, M = 2 and N = 1; or, M = 2 and N = 2.

The inlet air distribution component includes an inlet air housing, an inlet air frame 23, and an inlet air baffle 216. The inlet air housing forms an inlet air cavity, a main inlet air cavity, an upper support inlet air cavity, and a lower support inlet air cavity.

[0058] The air outlet assembly includes an air outlet housing, an air outlet frame, and an air outlet baffle. The air outlet housing forms an air outlet cavity, a main outlet of the air outlet cavity, an upper outlet of the air outlet cavity, and a lower outlet of the air outlet cavity. The air outlet cavity is cylindrical, with the main outlet of the air outlet cavity located at one axial end of the air outlet cavity. The upper outlet and lower outlet of the air outlet cavity are spaced apart along the circumference of the air outlet cavity. The air outlet frame is rotatably mounted inside the air outlet cavity around its centerline. An air outlet baffle is mounted on the side of the air outlet frame away from the centerline of the air outlet cavity. The air outlet baffle is rotatably mounted inside the air outlet cavity. When the air outlet baffle is controlled to rotate, the upper outlet and lower outlet of the air outlet cavity can be opened or closed. A sealing element 63 is provided on the side of the air outlet baffle away from the air outlet frame to seal the upper outlet and lower outlet of the air outlet cavity.

[0059] The following further describes the two-phase assembly 62 and the fan. The two-phase assembly 62 and the fan 61 are disposed between the upper roller 11 and the lower roller 12, and are arranged sequentially from front to back along the axial direction of the upper roller 11. The two-phase assembly 62 includes a two-phase box 621 and two phases. The two-phase box 621 forms two-phase chambers, two-phase chamber inlets, and two-phase chamber outlets. The two phases are disposed in the two-phase chambers and include an evaporator 622 and a condenser 623. The evaporator 622 is used to dehumidify the drying airflow, and the condenser 623 is used to heat the drying airflow. The fan 61 includes a fan housing and fan blades. The fan housing also forms a fan chamber, a fan chamber inlet, and a fan chamber outlet. The fan blades are rotatably disposed in the fan chamber.

[0060] The two-component assembly 62 is positioned at the center between the upper and lower rollers. The center plane of the two-component assembly 62 in the vertical direction is coplanar with the center plane of the fan 61 in the vertical direction, and the center plane of the two-component assembly 62 in the vertical direction passes through the axis of the upper roller 11 and the axis of the lower roller 12; this can increase the size of the two components or the heat exchange area, and improve the drying efficiency.
