[0038] like Figures 1 to 8 As shown, according to an embodiment of the present utility model, a clothes processing device is proposed, which can be used to dry washed clothes so that the clothes can be dried faster.

[0039] The clothes processing device of this embodiment includes a clothes processing chamber 110, a drying assembly, a first drying air passage 200, and a second drying air passage 300. The first drying air passage 200 is adapted to guide airflow to flow out of the clothes processing chamber 110 and flow through the drying assembly before returning to the clothes processing chamber 110. The second drying air passage 300 includes an auxiliary air duct structure 310, adapted to guide airflow to flow out of the clothes processing chamber 110 and flow through the auxiliary air duct structure 310 before returning to the clothes processing chamber 110.

[0040] The clothes processing device may include a drum 100 , and a clothes processing chamber 110 is formed inside the drum 100 , that is, clothes may be placed in the drum 100 for drying.

[0041] The first drying air path 200 is an air path that can both dry the airflow and form a circulating airflow, and can include a main air duct arranged outside the clothing processing chamber 110, and has an air inlet and an air outlet, and the air inlet and the air outlet are respectively connected to the clothing processing chamber 110, and the first drying air path 200 can provide a relatively high temperature airflow to the drum 100 to dry the clothes in the drum 100. Specifically, the clothing processing chamber 110 can be provided with an airflow inlet and an airflow outlet, the air inlet in the first drying air path 200 is connected to the airflow outlet, and the air outlet in the first drying air path 200 is connected to the airflow inlet, and the first drying air path 200 guides the airflow in the clothing processing chamber 110 to flow out from the airflow outlet, and after flowing through the drying component, it flows back to the clothing processing chamber 110 through the airflow inlet.

[0042] The clothing processing device may specifically be a heat pump dryer, in which case the drying component may include an evaporator and a condenser, etc. The clothing processing device may also be a washing and drying all-in-one machine, in which case the drying component may include a condenser and a heating tube, etc. Regardless of the form of the drying component, the drying component may be arranged in the first drying air path, and may specifically be arranged in the main air duct. This embodiment takes the example of a drying component including a condenser and an evaporator to briefly introduce the working principle of the first drying air path. The evaporator and the condenser may be arranged in sequence along the direction of air flow in the main air duct. A main fan component is also arranged in the first drying air path. The main fan component is used to provide air flow power in the main air duct. When the main fan component is activated, the air flow in the cylinder 100 may flow into the main air duct along the air flow inlet, and the air flow passes through the evaporator and the condenser in the main air duct in sequence and flows to the air flow outlet, and then flows back into the cylinder 100. Among them, the humid air flow after drying the clothes, after entering the main air duct from the drum 100, is first cooled by the evaporator to form condensed water, effectively removing moisture in the air flow to become a relatively dry air flow; then the dry air flow passing through the evaporator is heated by the condenser to form a dry air flow with a higher temperature, and this dry air flow with a higher temperature enters the drum 100 again, thereby forming a cycle to dry the clothes.

[0043] It should be noted that the airflow inlet and the airflow outlet of the laundry processing chamber 110 can be arranged as needed. In order to make the airflow in the laundry processing chamber 110 flow over a large range to improve the drying effect of the laundry, the airflow outlet and the airflow inlet can be arranged at opposite ends of the axial direction of the drum 100. Specifically, in some embodiments, such as Figure 1As shown, the first drying air passage 200 is provided with a front connecting support structure 201 at the front end of the cylinder 100, and an air duct connected with the main air duct is provided in the front connecting support structure 201. The air flow inlet can be provided at the front connecting support structure 201, that is, located at the front end of the cylinder 100, and can be circumferentially arranged around the front end of the cylinder 100. The air flow outlet in the first drying air passage 200 is provided at the rear end of the cylinder 100. That is to say, the air flow in the cylinder 100 flows from the rear end to the front end, and then flows into the main air duct of the first drying air passage 200 through the front end.

[0044] It should also be noted that the present embodiment only briefly introduces the main components of the first drying air duct 200 and the main components of the clothing processing device. The first drying air duct 200 may also include other components that assist in completing the drying function of the first drying air duct 200, and the clothing processing device may also include other functional components, which will not be described in detail here.

[0045] The second drying air path 300 is mainly used to promote the circulation of airflow in the clothing processing chamber 110, and no drying component may be provided therein. A connecting channel is formed inside the auxiliary air duct structure 310 so that the airflow can flow inside. An airflow drive component 320 may be provided in the second drying air path 300. The airflow drive component 320 may be provided in the channel of the auxiliary air duct structure 310, or may be provided at the air inlet or air outlet of the auxiliary air duct structure 310. The airflow drive component 320 is used to form an airflow driving power to circulate the airflow. The airflow drive component 320 may be a fan structure, specifically a suction fan or a blowing fan, or a bidirectional airflow drive fan. Among them, the bidirectional airflow driven fan is a fan that can switch the airflow driving direction. Usually, the fan can change the airflow driving direction by switching the rotation direction. For example, when the fan structure rotates forward, the fan drives the airflow from the first connecting port 301 to the second connecting port 302. When the fan structure rotates reversely, the fan structure drives the airflow from the second connecting port 302 to the first connecting port 301.

[0046] According to the clothes processing device of the utility model, when in use, clothes and other articles to be dried are placed in the clothes processing chamber 110, and the airflow is guided to flow through the first drying air path 200 and the second drying air path 300 to dry the clothes and the like. Among them, the first drying air path 200 can guide the wet airflow after drying the clothes and the like to the drying component, and the drying component forms a dry airflow after drying the wet airflow, and the dry airflow flows back to the clothes processing chamber 110 to dry the clothes again to form a cycle; the second drying air path 300 can guide the airflow in the clothes processing chamber 110 to flow out, and flow back to the clothes processing chamber 110 after passing through the auxiliary air duct structure. In this way, through the cooperation of the first drying air path 200 and the second drying air path 300, the circulation speed of the airflow in the clothes processing chamber 110 can be increased, so that the airflow flowing through the clothes processing chamber per unit time is increased, thereby improving the drying speed of the clothes by the clothes processing device, shortening the drying time, and improving the user experience.

[0047] The second drying air passage 300 of the clothing processing device of this embodiment can be connected to the clothing processing chamber 110 through the same air flow inlet and air flow outlet as the first drying air passage 200, and the clothing processing chamber 110 can also be provided with a separate connecting port corresponding to the second drying air passage 300 so that the second drying air passage 300 is connected to the clothing processing chamber 110.

[0048] In some embodiments, the second drying air duct 300 has a first communication port 301 and a second communication port 302. The first communication port 301 can be arranged at an interval relative to the second communication port 302, and the first communication port 301 and the second communication port 302 are connected through an auxiliary air duct structure 310. The first communication port 301 can be arranged on the outside of the side wall of the clothing processing chamber 110 (i.e., the outside of the drum 100), and communicate with the clothing processing chamber 110 through an opening on the clothing processing chamber 110, for example, it can communicate with the clothing processing chamber 110 through an air flow outlet. The first communication port 301 can also be arranged on the side wall of the clothing processing chamber 110, so that the first communication port 301 can be directly connected to the clothing processing chamber 110. Similarly, the second connecting port 302 can be arranged on the outside of the side wall of the clothing processing chamber 110 (i.e., the outside of the drum 100), and be connected with the clothing processing chamber 110 through an opening on the clothing processing chamber 110. For example, it can be connected with the clothing processing chamber 110 through an air flow inlet. The second connecting port 302 can also be arranged on the side wall of the clothing processing chamber 110, so that the second connecting port 302 can be directly connected with the clothing processing chamber 110.

[0049] When the clothing processing device is in use, the airflow driving component 320 can drive the airflow to flow, and any one of the second connecting port 302 and the first connecting port 301 serves as an air inlet connected to the auxiliary air duct structure 310, and the other serves as an air outlet connected to the auxiliary air duct structure 310. Specifically, when the airflow driving component 320 is operated and the airflow in the auxiliary air duct structure 310 flows from the first connecting port 301 to the second connecting port 302, the first connecting port 301 serves as an air inlet to guide the airflow in the cylinder 100 to the auxiliary air duct structure 310, and the second connecting port 302 serves as an air outlet to discharge the airflow in the auxiliary air duct structure 310 into the cylinder 100; when the airflow driving component 320 is operated and the airflow of the auxiliary air duct structure 310 flows from the second connecting port 302 to the first connecting port 301, the second connecting port 302 serves as an air inlet to guide the airflow in the cylinder 100 to the auxiliary air duct structure 310, and the first connecting port 301 serves as an air outlet to discharge the airflow in the auxiliary air duct structure 310 into the cylinder 100.

[0050] According to the clothing processing device of the present embodiment, the first connecting port 301 and the second connecting port 302 are arranged at intervals, so that the air inlet and the air outlet of the second drying air path 300 are connected with different areas of the drum 100. In this way, the second drying air path 300 can make the airflow flow from the position of the air outlet to the position of the air inlet in the drum 100, thereby better promoting the circulation of the airflow in the drum 100, strengthening the convection of the airflow, and increasing the circulation speed of the airflow inside the drum 100, so that the amount of air flowing through the inside of the drum 100 per unit time is increased, thereby improving the drying speed of the clothes by the clothing processing device, shortening the drying time, and improving the user experience.

[0051] In some technologies, in order to obtain a better drying speed, the temperature of the airflow cannot be increased due to the influence of the material of the clothes, and the contact area between the clothes and the airflow is also difficult to increase due to the size of the clothes processing equipment. Therefore, the basic means is usually to increase the operating power of the main fan assembly, which will cause the problem of excessive noise from the main fan assembly. The clothes processing equipment of this embodiment strengthens the internal self-circulation function of the airflow in the clothes processing chamber 110 through the second drying air duct 300, which only increases the airflow inside the drum 100 (i.e., in a local area), and does not change the airflow in the air duct of the whole machine, so it does not increase wind noise.

[0052] The clothing processing device may further include a housing 400, and the drum 100 may be disposed in the housing 400 and may be configured to be rotatable relative to the housing 400. Specifically, a motor and a transmission assembly connected to the motor may be disposed in the housing 400, and the motor drives the drum 100 to rotate through the transmission assembly. The first drying air duct 200 is mainly disposed between the drum 100 and the housing 400, and the first drying air duct 200 may be arranged to be relatively fixed to the housing 400, so that when the drum 100 rotates, the first drying air duct 200 may not rotate, so that the first drying air duct 200 is not affected by the rotation and has higher operating stability. The auxiliary drying system may be disposed in the drum 100, or may be disposed between the drum 100 and the housing 400.

[0053] Optionally, in some embodiments, the auxiliary air duct structure 310 includes a first air duct portion 311 , and the first air duct portion 311 extends along the axial direction of the cylinder 100 .

[0054] The first air channel portion 311 can extend from one axial end to the other end of the cylinder 100. The first air channel portion 311 is a part of the auxiliary air channel structure 310. Along the flow direction of the airflow, the first air channel portion 311 is located between the first connecting port 301 and the second connecting port 302, that is, the airflow entering the auxiliary air channel structure 310 will flow through the first air channel portion 311. It can be understood that the first air channel portion 311 can reasonably utilize the axial space of the cylinder 100, which is conducive to increasing the distance between the first connecting port 301 and the second connecting port 302 as needed, so that under the action of the second drying air duct 300, the airflow in the cylinder 100 has a larger flow range between the first connecting port 301 and the second connecting port 302, which can improve the convection effect of the airflow in the cylinder 100. The first air channel portion 311 may be disposed on the outer surface of the clothing processing chamber 110 or outside the outer surface, that is, outside the drum 100 , or may be disposed inside the side wall of the drum 100 , or may be disposed on the inner surface of the clothing processing chamber 110 .

[0055] In some embodiments, the first communication port 301 and the second communication port 302 are disposed on the circumferential side wall of the laundry processing chamber so that the second drying air passage 300 is directly connected to the laundry processing chamber 110. The first communication port 301 and the second communication port 302 may be spaced apart in the axial direction of the laundry processing chamber 110, or may be spaced apart in the circumferential direction of the laundry processing chamber 110.

[0056] Specifically, in some embodiments, referring to Figures 2 to 5As shown, optionally, the first air channel portion 311 is disposed on the inner surface of the laundry processing chamber 110 and connected thereto. Specifically, the first air channel portion 311 may be an integrally formed structure with the barrel 100, or connected thereto as an integral structure. In one implementation, the first air channel portion 311 may be used as a reinforcing rib of the barrel 100 to improve the strength of the barrel 100. In other words, the reinforcing rib of the barrel 100 may be modified to form a connecting port and an air channel to be used as the first air channel portion 311.

[0057] The first communication port 301 and the second communication port 302 may both be arranged on the first air channel portion 311. Specifically, in one implementation, the first communication port 301 and the second communication port 302 may be arranged on the same first air channel portion 311, and may be arranged on the side walls of the first air channel portion 311 at both ends along the axial direction of the cylinder 100, respectively, so as to increase the spacing between the second communication port 302 and the first communication port 301, so that the airflow in the cylinder 100 can flow from one axial end of the cylinder 100 to the other axial end under the action of the second drying air duct 300, thereby increasing the circulation speed of the airflow. It should be noted that, in this implementation, usually, the air inlet and the air outlet in the second drying air passage 300 are determined, that is, when the clothing processing equipment is running, one of the first connecting port 301 and the second connecting port 302 that serves as the air inlet always serves as the air inlet, and the other that serves as the air outlet always serves as the air outlet, and the air inlet in the second drying air passage 300 and the air inlet in the first drying air passage 200 are located at the same end of the cylinder 100 (one end of the cylinder 100 in the axial direction), and the air outlet in the second drying air passage 300 and the air outlet in the first drying air passage 200 are located at the same end of the cylinder 100 (the other end of the cylinder 100 in the axial direction). In this way, the second drying air passage 300 and the first drying air passage 200 can form an airflow driving force in the same direction in the cylinder 100, thereby improving the convection capacity of the airflow in the cylinder 100. It should also be noted that, in the present embodiment, a plurality of first air duct portions 311 may be provided, the airflow directions in the plurality of first air duct portions 311 may be the same, and the plurality of first air duct portions 311 may be respectively provided with airflow driving components 320 to drive the airflow; the plurality of first air duct portions 311 may also be interconnected and share the airflow driving component 320.

[0058] In another implementation, combining Figures 2 to 5 As shown, the first air duct portion 311 includes a plurality of sub-air duct portions 3111, any one of the sub-air duct portions 3111 extends in the axial direction of the clothing processing chamber 110, the plurality of sub-air duct portions 3111 are arranged in sequence and spaced apart along the circumference of the barrel 100, and the plurality of sub-air duct portions 3111 are connected to each other, and the first connecting port 301 and the second connecting port 302 are arranged on different sub-air duct portions 3111 among the plurality of sub-air duct portions 3111.

[0059] The first communication port 301 is provided on at least one of the plurality of sub-air duct portions 3111, and the second communication port 302 is provided on at least another of the plurality of sub-air duct portions 3111, that is, at least one of the sub-air duct portions 3111 is provided with the first communication port 301, and at least one of the sub-air duct portions 3111 is provided with the second communication port 302. Meanwhile, the sub-air duct portion 3111 provided with the first communication port 301 is not provided with the second communication port 302, and the sub-air duct portion 3111 provided with the second communication port 302 is not provided with the first communication port 301. In this way, by setting the first connecting port 301 and the second connecting port 302 on different sub-air duct portions 3111, the first connecting port 301 and the second connecting port 302 can be spaced apart in the circumferential direction of the cylinder 100 to increase the distance between the second connecting port 302 and the first connecting port 301, thereby improving the strengthening effect of the second drying air duct 300 on airflow convection.

[0060] In a specific embodiment, the first air duct portion 311 includes two sub-air duct portions 3111, and the two sub-air duct portions 3111 can be arranged on two opposite sides of the cylinder 100 in the radial direction. A first connecting port 301 is arranged on one of the sub-air duct portions 3111, and a second connecting port 302 is arranged on the other sub-air duct portion 3111. In this way, the radial distance between the first connecting port 301 and the second connecting port 302 in the cylinder 100 can be maximized, which is beneficial to improving the strengthening effect of the second drying air duct 300 on air flow convection.

[0061] The sub-air duct portion 3111 can be arranged in the lifting rib of the barrel 100, the first connecting port 301 can be arranged on the side of the sub-air duct portion 3111 facing the central axis of the barrel 100, and the second connecting port 302 can also be arranged on the side of the corresponding sub-air duct portion 3111 facing the central axis of the barrel 100. In this way, the first connecting port 301 and the second connecting port 302, as one of the air inlets, can positively absorb the airflow of the barrel 100, and the first connecting port 301 and the second connecting port 302, as one of the air outlets, can also make the airflow blow positively toward the clothes in the barrel 100, which is beneficial to enhance the airflow convection effect in the area where the clothes are located, thereby improving the drying effect on the clothes.

[0062] Optionally, in order to make the multiple sub-air duct parts 3111 better connected, continue to refer to Figures 2 to 5 As shown, in some embodiments, the auxiliary air duct structure 310 includes a second air duct portion 312 , which extends along the circumference of the cylinder 100 and is connected to a plurality of sub-air duct portions 3111 .

[0063] Among them, the second air duct portion 312 can be a closed ring structure extending in the circumferential direction of the cylinder 100 and connected end to end. The second air duct portion 312 can also be a local annular structure connecting multiple sub-air duct portions 3111. For example, when the first air duct portion 311 includes two sub-air duct portions 3111 arranged opposite to each other in the radial direction of the cylinder 100, the second air duct portion 312 can be set only as a semi-ring structure. The second air duct portion 312 can be arranged on the inner side of the barrel 100, and can also be arranged on the outer side of the barrel 100. Since the second air duct portion 312 and the first air duct portion 311 can be arranged to rotate with the barrel 100 in the present embodiment, in order to reduce the influence of the second air duct portion 312 and other components outside the barrel 100, the second air duct portion 312 can be arranged on the inner side of the barrel 100. Specifically, the second air duct portion 312 can be arranged on the inner wall of the barrel 100 close to the axial end, for example, it can be on the inner wall of the barrel 100 close to the rear end, so as to reduce the influence of the second air duct portion 312 on the clothing taking-in and putting-out port 101 of the barrel 100.

[0064] In the auxiliary air duct structure 310 provided with the second air duct portion 312, the airflow drive assembly 320 can be arranged in the second air duct portion 312, or in the first air duct portion 311. The number of airflow drive assemblies 320 can be one or two or more. In a specific embodiment, the airflow drive assembly 320 is arranged in the second air duct portion 312, and two airflow drive assemblies 320 are arranged at intervals. In the case where the airflow drive assembly 320 is a fan structure, the power cord of the fan structure can be connected to an external power source through a rotating wire connector, so that the fan structure can operate normally when rotating with the cylinder 100. In some embodiments, the fan structure can be arranged in a space near the rear end of the cylinder 100, and the rotating wire connector is arranged in the space between the cylinder 100 and the housing 400.

[0065] It should be noted that the front-to-back direction of the drum 100 is consistent with the axial direction of the drum 100, and the front end of the drum 100 refers to the end of the drum 100 where the clothing access port 101 is located, and the rear end of the drum 100 refers to the end of the drum 100 opposite to the clothing access port 101.

[0066] It should also be noted that, in the scheme where the first connecting port 301 and the second connecting port 302 are arranged in different sub-air duct portions 3111 among multiple sub-air duct portions 3111, a bidirectional airflow drive fan that can rotate both forward and reverse can be used as the airflow drive component 320. In this way, the airflow flow direction of the second drying air duct 300 can be switched according to the rotation of the drum 100 to enhance the convection effect of the airflow. Specifically, the barrel 100 may be a drum-type structure, which rotates along a substantially horizontal axis, and during the rotation of the barrel 100, when the sub-air duct portion 3111 is within the range capable of contacting clothes, the connecting port on the sub-air duct portion 3111 can exhaust air into the barrel 100, and when the sub-air duct portion 3111 is within the range not in contact with clothes, the connecting port on the sub-air duct portion 3111 can inhale air from the barrel 100. That is to say, during the rotation of the barrel 100, the sub-air duct portion 3111 rotates with the barrel 100, so the position of the sub-air duct portion 3111 in the circumferential wind direction is dynamic, and the connecting port of the sub-air duct portion 3111 that rotates to contact with clothes in the barrel 100 serves as an air outlet, and the connecting port of the sub-air duct portion 3111 that rotates not in contact with clothes in the barrel 100 can serve as an air inlet.

[0067] like Figure 6 As shown, taking the case where the drum 100 of the clothing processing device rotates clockwise B from the front as an example, the clothing is lifted by the corresponding sub-air duct portion 3111 on the left side of the dotted line A, and the sub-air duct portion 3111 on this side is in contact with the clothing; when the sub-air duct portion 3111 is located on the right side of the dotted line A, the sub-air duct portion 3111 does not contact the clothing. The angle α of the dotted line A is generally 30 to 80 degrees, and the specific degree is related to the rotation speed of the drum 100 and the material of the clothing. The greater the rotation speed or the greater the friction coefficient between the clothing and the sub-air duct portion 3111, the smaller the α value. The wind of the second drying air path 300 needs to be always sucked in from the sub-air duct portion 3111 on the right side of the dotted line A, and then blown out from the sub-air duct portion 3111 on the left side of the dotted line A. In this way, it can be ensured that the air inlet of the second drying air path 300 will not suck the clothing. In addition, the air outlet can blow air from the bottom of the clothing, which is conducive to the shaking and ventilation of the clothing, and has the effect of promoting evaporation. It should be noted that in order to achieve the above-mentioned reversing control of the airflow in the second drying air duct 300, the wind direction switching of the airflow driving assembly 320 can be controlled in conjunction with the rotation of the drum. In the case of two sub-air duct portions 3111 arranged radially opposite to each other, the drum body 100 can change the wind direction every half a circle, and the timing for changing the wind direction is when the two sub-air duct portions 3111 turn to the dotted line A position.

[0068] Optionally, in some embodiments, Figure 7 and Figure 8As shown, the first air channel portion 311 can also be connected to air channel portions at both ends of the axial direction, and a communication port is provided through the air channel portion at the end, so as to communicate with the inside of the cylinder 100. For the convenience of description, the air channel portion at one axial end of the first air channel portion 311 is defined as the third air channel portion 313, and the air channel portion at the other axial end of the first air channel portion 311 is defined as the fourth air channel portion 314. The third air channel portion 313 is provided with a first communication port 301, and the second air channel portion 312 is provided with a second communication port 302. Among them, the third air channel portion 313 and the fourth air channel portion 314 are respectively located at the two ends of the axial direction of the cylinder 100, and can extend in the radial direction of the cylinder 100 respectively. Along the radial direction of the cylinder 100, the third air channel portion 313 and the fourth air channel portion 314 can extend into the inner side of the inner wall of the cylinder 100 respectively, so that the first connecting port 301 on the third air channel portion 313 and the second connecting port 302 on the fourth air channel portion 314 can be connected to the cylinder 100 in the axial direction, thereby improving the air flow efficiency. In this embodiment, the airflow drive assembly 320 can be arranged in the first air channel portion 311, the third air channel portion 313 or the fourth air channel portion 314. In order to reasonably use the space, the airflow drive assembly 320 can be arranged in the first air channel portion 311.

[0069] The third air channel portion 313 and the fourth air channel portion 314 may be disposed on the inner surface of the laundry processing chamber 110 together with the first air channel portion 311, or may be disposed on the outer surface or the outer side of the outer surface of the laundry processing chamber 110. This embodiment is described by taking the third air channel portion 313 and the fourth air channel portion 314 disposed on the outer side of the outer surface of the laundry processing chamber 110 as an example.

[0070] In some embodiments, the first connecting port 301 is an air inlet, the second connecting port 302 is an air outlet, the first connecting port 301 and the air flow outlet are located at the first axial end of the cylinder 100, and the second connecting port 302 and the air flow inlet are located at the second axial end of the cylinder 100.

[0071] The first end and the second end are two opposite ends of the cylinder 100 in the axial direction.

[0072] Specifically, the first connecting port 301 serving as the air inlet and the air inlet in the first drying air passage 200 can both be located at the front end of the cylinder 100, and the second connecting port 302 serving as the air outlet and the air outlet of the first drying air passage 200 can both be located at the rear end of the cylinder 100, so that the airflow in the cylinder 100 flows from the rear end to the front end.

[0073] The air flow outlet of the clothing processing chamber 110 is arranged at the same end as the air inlet of the two drying air paths, and the air flow inlet of the clothing processing chamber 110 is arranged at the same end as the air inlet of the two drying air paths. In this way, the second drying air path 300 and the first drying air path 200 can form an air flow driving force in the same direction in the drum 100, thereby improving the convection capacity of the air flow in the drum 100.

[0074] In the scheme where the first air channel portion 311, the third air channel portion 313 and the fourth air channel portion 314 cooperate, the first air channel portion 311 can be arranged outside the barrel 100, the third air channel portion 313 is arranged outside the first end of the barrel 100, the fourth air channel portion 314 is arranged outside the second end of the barrel 100, and the first communication port 301 and the second communication port 302 are respectively connected to the laundry processing chamber 110 through the openings at the corresponding ends of the barrel 100. Among them, the openings at the corresponding ends of the barrel 100 can be the airflow inlet and airflow outlet of the laundry processing chamber 110.

[0075] In one implementation, the third air channel portion 313 is disposed on the outside of the front end of the barrel 100, and extends from the outside of the circumferential side wall of the barrel 100, along the radial direction of the front end surface of the barrel 100 to the axis of the barrel 100, and the first communication port 301 is connected to the inside of the laundry processing chamber 110 through the clothing access port 101 (corresponding to the formation of the air flow outlet). The fourth air channel portion 314 is disposed on the outside of the rear end of the barrel 100, and extends from the outside of the circumferential side wall of the barrel 100, along the radial direction of the rear end surface of the barrel 100 to the axis direction of the barrel 100, and the second communication port 302 is connected to the inside of the laundry processing chamber 110 through the opening (i.e., the air flow inlet) at the rear end of the barrel 100.

[0076] It can be understood that the first air duct portion 311, the third air duct portion 313 and the fourth air duct portion 314 are arranged on the outside of the cylinder 100, the vacant position outside the cylinder 100 can be utilized, and the impact of the setting of the second drying air duct 300 on the internal space of the cylinder 100 can be reduced.

[0077] In some technical solutions, viewed from the front of the drum 100, the drum 100 is set to rotate clockwise B, and the clothes are mainly concentrated on the left side of the dotted line A of the drum 100. The first drying air path 200 of the drum 100 will focus on occupying the left space between the drum 100 and the shell 400. There is a vacant position in the local area of ​​the upper right corner of the drum 100, and the first air duct portion 311 can be installed there.

[0078] In the case where the first air duct portion 311 is arranged on the outside of the barrel 100, if the first air duct portion 311 rotates with the barrel 100, it will occupy more space, which is not conducive to the space utilization of the whole machine. In view of this, the first air duct portion 311 can be relatively fixed to the shell 400. Specifically, the first air duct portion 311 can be connected to the shell 400 directly or through a connector, so that the first air duct portion 311 can only occupy the space of the shell 400 and the barrel 100 in a local area, so that the idle position is reasonably utilized, which is conducive to improving the space utilization of the whole machine. It should be noted that the third air duct portion 313 and the fourth air duct portion 314 can be fixedly connected to the two ends of the first air duct portion 311, so that the third air duct portion 313 and the fourth air duct portion 314 can be fixedly supported by the first air duct portion 311 and remain relatively fixed with the shell 400.

[0079] In some embodiments, a porous structure 102 is provided at the rear end of the cylinder 100, and the through holes of the porous structure 102 form an airflow inlet at the rear of the cylinder 100, and the airflow flowing out of the air outlet of the first drying air duct 200 flows into the cylinder 100 through the porous structure 102. In the case where a fourth air channel portion 314 is provided on the outside of the cylinder 100, the airflow flowing out of the second connecting port 302 of the fourth air channel portion 314 can also flow into the cylinder 100 through the porous structure 102.

[0080] In order to reduce the impact of hair debris generated during the clothes drying process on the fan, a filter structure 330 is also provided in the auxiliary air duct structure 310. The filter structure 330 can be a filter net. The filter structure 330 is suitable for airflow to pass through and can block hair debris. Specifically, the first connecting port 301 and the second connecting port 302 can be respectively provided with a filter structure 330, so that hair debris in the airflow entering the auxiliary air duct structure 310 is filtered and hair debris is not easy to enter the airflow driving component 320; the filter structure 330 can also be provided on the inlet of the airflow driving component 320 to reduce the possibility of hair debris entering the airflow driving component 320.

[0081] The filter structure 330 can be detachably mounted on the auxiliary air duct structure 310 to facilitate cleaning of the filter structure 330 .

[0082] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
