[0037] In order to enable those skilled in the art to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.
[0038] In the related art, the air inlet end of the air intake duct 3 is connected to the air outlet part 2 of the shell 1, and the angle between the air intake duct 3 and the radial direction of the wheel in the shell 1 is an obtuse angle, which causes the airflow to easily form vortices when entering the air intake duct 3, causing the airflow to accumulate at the connection transition between the shell 1 and the air intake duct 3, affecting the output of the airflow and also affecting the drying efficiency of the objects.
[0039] Based on the above technical problems, the present application provides a drying module and a clothing processing device, which aims to at least to some extent solve the technical problem that the airflow accumulates at the connection transition between the shell 1 and the air inlet channel, affecting the output of the airflow, so as to improve the drying efficiency of clothes.
[0040] Figure 1 shows a schematic structural diagram of a drying module in some embodiments, Figure 2 A cross-sectional view of a drying module and an air intake duct according to an embodiment of the present application is shown. Figure 3 FIG2 shows a cross-sectional view of a drying module and an air intake duct according to another embodiment of the present application. Figure 1-Figure 3The drying module provided in the present application includes a shell 1, a wheel disc 4 and an air intake duct 3. The wheel disc 4 is arranged in the shell 1. The shell 1 is provided with an air outlet 2. The air outlet 2 of the shell 1 is connected to the air intake duct 3 to output the airflow in the shell 1 through the air intake duct 3, wherein: the air outlet 2 is provided with a first guide wall 21 for guiding the airflow. The first guide wall 21 is arranged close to the wheel disc 4. At least a portion of the first guide wall 21 is provided with a buffer portion 211 to lift the airflow entering the air outlet 2 to buffer the airflow to a certain extent, so as to avoid the formation of vortexes when the airflow enters the air intake duct 3, and the phenomenon of airflow accumulation at the connection transition between the shell 1 and the air intake duct 3, so as to improve the output of the airflow and improve the drying efficiency of objects.
[0041] Combine Figure 2 According to one embodiment of the present application, the buffer portion 211 can be parallel to the radial direction of the wheel disc 4, and at least a part of the top of the buffer portion 211 is higher than the bottom of the wheel disc 4. The airflow generated from the wheel disc 4 can be guided and lifted by the buffer portion 211, and then enter the air outlet portion 2 and the air inlet duct 3 to buffer the airflow, improve the output of the airflow, and improve the drying efficiency of the objects.
[0042] Combine Figure 2 The wheel disc 4 is arranged horizontally or nearly horizontally, and the top of the buffer portion 211 can be flat and slightly lower than the top of the wheel disc 4. This ensures that the airflow area entering the air outlet portion 2 is guaranteed, thereby increasing the airflow output and improving the drying efficiency of the objects. In other embodiments, the top of the buffer portion 211 can also be flush with the top of the wheel disc 4, or slightly higher than the top of the wheel disc 4, which is not limited here.
[0043] Combine Figure 3 According to another embodiment of the present application, the direction of the airflow flowing on the buffer portion 211 is arranged at an angle to the radial direction of the wheel disc 2, so as to lift the airflow generated in the shell 1 and buffer the airflow to a certain extent, so as to avoid the formation of vortices when the airflow enters the air intake duct, and the accumulation of airflow at the connection transition between the shell and the air intake duct, so as to improve the output of the airflow and improve the drying efficiency of the objects.
[0044] Combine Figure 3According to one embodiment of the present application, at least a portion of the buffer portion 211 is a bevel 211a, and the angle between the bevel 211a and the radial direction of the wheel disc 4 is between 5-20 degrees, for example, 5 degrees, 10 degrees, or 20 degrees. If the angle between the bevel 211a and the radial direction of the wheel disc 4 is too large, the airflow will be deviated by too large an angle when entering the air outlet portion 2, which may easily cause the airflow to form vortices when entering the air outlet portion 2. If the angle is too small, it will not play the role of buffering the airflow. Therefore, the present application sets the angle between the bevel 211a and the radial direction of the wheel disc 4 to between 5-20 degrees to buffer the airflow, avoid the generation of vortices, and improve the drying efficiency.
[0045] According to another embodiment of the present application, at least a portion of the buffer portion 211 may be a curved surface 211 b to lift the airflow generated in the housing 1 and make the airflow flow smoother. Figure 5 The schematic diagram shows the connection between the air outlet of the drying module and the air inlet pipe when the buffer portion is an arc surface. Figure 5 The angle between the tangent of the midpoint of the arc surface 211b and the radial direction of the wheel disc 4 is between 5-20 degrees. The reasons for the angle setting can be referred to the above description and will not be repeated here.
[0046] Figure 6 as well as Figure 7 The schematic diagram shows the connection between the air outlet of the drying module and the air inlet pipe when the buffer portion is a combination of an arc surface and an inclined surface. Figure 6 as well as Figure 7 In some embodiments, the buffer portion 211 may include an inclined surface 211a and an arc surface 211b, and the inclined surface 211a and the arc surface 211b extend in the direction of the intake duct 3 (eg Figure 6 Alternatively, the arc surface 211b and the inclined surface 211a extend in the direction of the air intake duct 3 in sequence (as Figure 7 In practice, the angle between the inclined surface 211a and the radial direction of the wheel disc 4 is between 5-20 degrees, and the angle between the tangent line at the midpoint of the arc surface 211b and the radial direction of the wheel disc 4 is between 5-20 degrees. The reasons for setting these angles can be found in the above description and will not be elaborated here.

[0048] According to another embodiment of the present application, the buffer portion 211 may also be directly connected to the air intake duct 3 without being transitionally connected through the transition portion 212 .
[0049] Combine Figure 3-Figure 7 In some embodiments, the air outlet 2 is provided with a second guide wall 22 for guiding airflow. The second guide wall 22 is disposed away from the wheel disc 4 and opposite to the first guide wall 21. The second guide wall 22 is disposed parallel or nearly parallel to the radial direction of the wheel disc 4. The second guide wall 22 can restrict the flow direction of the airflow to guide the airflow from the air outlet 2 of the housing 1 to the air inlet duct 3.

The first housing 11 is disposed above the second housing 12. The second housing 12 is provided with a receiving cavity 13 for accommodating the moisture absorption and dehumidification wheel 4. The air outlet 2 of the housing 1 is disposed within the first housing 11, and the edge of the second housing 12 is disposed at the entrance of the air outlet 2 of the housing 1. In order to realize the provision of the above-mentioned buffer portion 211, the present application also improves the structure of the housing 1.

The transition portion 212 of the first guide wall 21 can be connected to the bottom of the outlet cavity 14. That is, the transition portion 212 and the buffer portion 211 are provided separately. When the first housing 11 and the second housing 12 are assembled together, the transition portion 212 and the buffer portion 211 abut against each other to form the first guide wall 21.
