[0038] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0039] In related technologies, clothing processing equipment such as dryers use impellers to drive airflow circulation to dry clothes. However, the noise generated by the impeller rotation is relatively large, which affects the user experience. Therefore, how to optimize the impeller structure and reduce noise has become an urgent problem to be solved in this field.

[0040] The following is for reference. Figures 1-8 This invention describes a base assembly for a garment processing device according to an embodiment of the present invention.

[0041] The base assembly 1 for a garment processing device according to the present invention includes: a base 10, the base 10 having an installation cavity 103 communicating with the inner cylinder of the garment processing device; and an impeller 11, the impeller 11 being rotatably disposed on the base 10, the impeller 11 having a first impeller portion 111 and a second impeller portion 112 coaxially disposed, the first impeller portion 111 and the second impeller portion 112 having blades arranged in the circumferential direction respectively, the blades of the first impeller portion 111 and the blades of the second impeller portion 112 being alternately disposed.

[0042] Specifically, a mounting cavity 103 for accommodating the impeller 11 is formed on the base 10. The mounting cavity 103 communicates with the inner drum. The impeller 11 is rotatably disposed within the mounting cavity 103. The rotation of the impeller 11 guides the airflow within the mounting cavity 103 into the inner drum and acts on the clothes to perform a drying or blow-drying operation. The impeller 11 has a first impeller portion 111 and a second impeller portion 112 disposed in a common configuration. Figure 3 and Figure 4 As shown, the blades on the first impeller section 111 and the blades on the second impeller section 112 are staggered in the circumferential direction. During the rotation of the impeller 11, the first impeller section 111 and the second impeller section 112 rotate synchronously. The blades of the first impeller section 111 and the blades of the second impeller section 112 rotate together on both sides of the axial direction and guide the airflow, improving the airflow guiding effect. The staggered arrangement of the blades on both sides of the impeller 11 means that when the impeller 11 rotates, the staggered blades on both sides of the impeller 11 simultaneously agitate the airflow, optimizing the airflow and reducing the rotation and eddies of the airflow in the impeller, thereby reducing the noise caused by the unstable airflow. At the same time, the staggered arrangement of the blades balances the pressure distribution on both sides of the impeller 11 and reduces the force-bearing area of ​​the blades, thereby enhancing the stability of the impeller 11. The stable operating state helps to reduce the noise caused by vibration and unstable airflow.

[0043] According to the present invention, the base assembly 1 for a clothing processing device has a mounting cavity 103 formed on the base 10 that communicates with the inner drum. The impeller 11 is rotatably disposed in the mounting cavity 103. By rotating the impeller 11, airflow can be guided from the mounting cavity 103 into the inner drum to dry or blow dry the clothes. The impeller 11 has a first impeller portion 111 and a second impeller portion 112 coaxially arranged. The blades of the first impeller portion 111 and the blades of the second impeller portion 112 are staggered in the circumferential direction. When the impeller 11 rotates, the staggered blades balance the pressure distribution on both sides of the impeller 11 in the axial direction, reduce the force-bearing area of ​​the blades, and thus enhance the stability of the impeller 11. The stable operating state helps to reduce noise caused by vibration and unstable airflow.

[0044] According to some embodiments of the present invention, the base assembly 1 further includes: a volute 12, which is sleeved on the outer periphery of the impeller 11 and rotatably connected to the impeller 11. The volute 12 has a first airflow inlet 161 and a second airflow inlet 162 that are open on both sides of the axial direction. The first airflow inlet 161 is directly opposite to the first impeller portion 111, and the second airflow inlet 162 is directly opposite to the second impeller portion 112. The volute 12 is also provided with an airflow outlet 163 that communicates with the inner cylinder.

[0045] Specifically, a first airflow inlet 161 and a second airflow inlet 162 are formed on both sides of the volute 12. The airflow in the mounting cavity 103 can flow into the volute 12 through the first airflow inlet 161 and the second airflow inlet 162 under the guidance of the impeller 11, thereby improving the air intake effect of the volute 12. The airflow in the volute 12 flows out through the airflow outlet 163 under the guidance of the impeller 11 and enters the inner cylinder. Since the blades of the first impeller part 111 and the second impeller part 112 are staggered, as the impeller 11 rotates, when the fluid enters through the airflow inlet of the volute 12, the airflow will be accelerated and guided by the staggered blades, thereby generating a more uniform and efficient fluid flow, making the clothes in the inner cylinder more evenly stressed, and improving the performance and efficiency of the clothes handling equipment.

[0046] According to some embodiments of the present invention, the volute 12 includes: an arc-shaped plate 121, one end of the arc-shaped plate 121 extending in the direction of the other end being bent toward each other and spaced apart to define an airflow outlet 163; a first side plate 122 and a second side plate 123, the first side plate 122 and the second side plate 123 being respectively disposed on both sides of the arc-shaped plate 121 in the axial direction, a first airflow inlet 161 being formed on the first side plate 122, and a second airflow inlet 162 being formed on the second side plate 123; wherein, the arc-shaped plate 121, the first side plate 122 and the second side plate 123 together define a first air duct 171 communicating with the airflow outlet 163, the first airflow inlet 161 and the second airflow inlet 162, and the impeller 11 being rotatably disposed within the first air duct 171.

[0047] like Figure 1 and Figure 2As shown, an arc-shaped plate 121 is arranged around the radial outer periphery of the impeller 11, forming an annular structure surrounding the impeller 11. The arc-shaped plate 121 is spaced apart at one end and the other end in the extending direction, thereby defining the airflow outlet 163. The rotation of the impeller 11 drives the airflow to flow out from the inside of the volute 12 through the airflow outlet 163 and into the inner cylinder. The first side plate 122 and the second side plate 123 are located on both sides of the arc-shaped plate 121 in the axial direction and are connected to the edge of the arc-shaped plate 121. A first airflow inlet 161 is formed on the first side plate 122, and a second airflow inlet 162 is formed on the second side plate 123. The first side plate 122 and the second side plate 123, together with the arc-shaped plate 121, jointly define the first airflow channel 171 inside the volute 12. The first airflow channel 171 defines the flow direction of the airflow inside the volute 12, making the airflow more concentrated and improving the flow intensity. By combining the arc plate 121, the first side plate 122, and the second side plate 123, the volute 12 forms a closed or semi-closed structure to guide and control the flow of air, ensuring that the airflow is fully guided inside the volute 12, reducing the flow resistance of the airflow to ensure the flow intensity of the airflow, and reducing the noise generated by the rotation of the impeller 11, thus improving the noise reduction effect.

[0048] According to some embodiments of the present invention, the volute 12 is constructed in multiple ways, with the multiple volutes 12 arranged at axial intervals, and each volute 12 has an impeller 11 rotatably disposed inside.

[0049] Specifically, the volute 12 is constructed as multiple volutes spaced axially, each containing an impeller 11. By increasing the number of volutes 12 and impellers 11, the airflow can be increased, allowing clothes to be subjected to stronger airflow, thus improving the efficiency and quality of clothes handling. The volute 12 also seals the impellers 11, reducing noise generated by their operation. The multiple volutes 12 are axially spaced, and the impellers 11 installed inside each volute 12 are axially aligned. The rotation axes of the multiple impellers 11 extend in the same direction, facilitating simultaneous motor operation with multiple impellers 11 and motor rotation. This increases airflow while reducing the space occupied by the impeller and motor, improving space utilization. The airflow outlets 163 of the multiple volutes 12 all open in the same direction towards the inner drum, further increasing airflow and improving clothes handling efficiency.

[0050] According to some embodiments of the present invention, the base assembly 1 further includes: a first motor 131, wherein the first motor 131 is configured as at least one and disposed between two adjacent volutes 12, and the first motor shaft 1311 forms a first motor shaft 1311 and a second motor shaft 1312 extending away from each other on both sides, and the first motor shaft 1311 and the second motor shaft 1312 are respectively adapted to drive the impeller 11 to rotate.

[0051] Specifically, a first motor 131 is provided between two adjacent volutes 12. The first motor shaft 1311 forms a first motor shaft 1311 and a second motor shaft 1312 on both sides. The first motor shaft 1311 and the second motor shaft 1312 extend toward the volute 12, so that the first motor 131 can cooperate with the impeller 11 in the volute 12 and drive the impeller 11 to rotate. By driving the two impellers 11 to rotate simultaneously by the first motor 131, the rotation speed of the two impellers 11 can be guaranteed to be the same, thereby optimizing the airflow and ensuring that the airflow can act more evenly on the clothes in the inner drum, thus ensuring drying efficiency. Furthermore, by driving the two impellers 11 to rotate by a single motor, not only is the space utilization of the installation cavity 103 saved, but the overall cost of the clothes processing equipment is also reduced.

[0052] According to some embodiments of the present invention, the base 10 includes: a housing 101, in which an installation cavity 103 is formed that opens toward the top; and a cover plate 102, which is disposed on the top of the housing 101 and forms a cavity outlet 164 that is directly opposite to the airflow outlet 163, and the cavity outlet 164 is connected to the inner cylinder.

[0053] Specifically, the base 10 includes a housing 101 and a cover plate 102. An installation cavity 103 that opens to the top is formed inside the housing 101. Structures such as impellers and motors can be placed inside the installation cavity 103. The cover plate 102 covers the opening of the installation cavity 103. At this time, the cover plate 102 and the housing 101 can serve as a sound insulation structure for the impeller 11, which helps to reduce the noise generated by the impeller 11 during operation and improve the noise reduction performance of the clothing processing equipment. A cavity outlet 164 is formed on the cover plate 102, which connects the mounting cavity 103 and the inner drum. The rotation of the impeller 11 can drive the airflow in the mounting cavity 103 to flow through the cavity outlet 164 into the impeller 11, thereby drying the clothes inside the inner drum. By providing a cavity outlet 164 on the cover plate 102 to connect the mounting cavity 103 and the inner drum, the airflow path can be reduced and the drying efficiency can be improved. The cavity outlet 164 is open towards the inner drum, so that the airflow can flow directly into the inner drum. The impeller 11 is located near the cavity outlet 164, which can improve the airflow efficiency and further improve the clothes handling efficiency.

[0054] According to some embodiments of the present invention, the base 10 has a cavity inlet 165 communicating with the mounting cavity 103. A heat exchanger 14 for heat exchange of the airflow in the mounting cavity 103 is provided in the mounting cavity 103. The heat exchanger 14 is disposed between the cavity inlet 165 and the airflow inlet.

[0055] Specifically, the heat exchanger 14 can be configured as a condenser or an evaporator. After the external airflow enters the mounting cavity 103 through the cavity inlet 165, it first passes through the heat exchanger 14. After being heated by the heat exchanger 14, the airflow flows through the volute 12 and the impeller. Under the guidance of the impeller, it flows into the inner cylinder to dry or blow dry the clothes. By setting the heat exchanger 14 between the impeller 11 and the airflow inlet, it is convenient for the heat exchanger 14 to heat the airflow and flow into the first air duct 171, making the airflow in the entire mounting cavity 103 simpler, without unnecessary bends, and reducing airflow resistance.

[0056] The following is a brief description of a clothing processing device according to another embodiment of the present invention.

[0057] The garment processing device according to the present invention includes: a housing 15, wherein an installation space suitable for accommodating an inner tube is formed inside the housing 15; a base 10, wherein the base 10 is constructed as described in any of the above embodiments, the base 10 is disposed at the bottom of the housing 15 to enclose the installation space, and an installation cavity 103 and a cavity outlet 164 communicating the installation cavity 103 with the inner tube are formed on the base 10.

[0058] Specifically, the outer shell 15, as the main structure of the garment processing equipment, provides installation space for the inner drum, can seal and protect the inner drum, and can reduce the noise generated by the inner drum during operation. The outer shell 15 is located on the top of the base 10 to seal and protect the inner drum and other components such as the air supply component. Since the base 10 is constructed as described in any of the above embodiments, an installation cavity 103 is formed on the base 10 for accommodating the impeller 11 and the air supply component, heat exchange component 14, etc., and airflow inlets are formed on both sides of the air supply component along the axial direction, thereby increasing the airflow guided by the impeller 11 and thus improving the garment processing effect of the garment processing equipment.

[0059] According to some embodiments of the present invention, the garment processing device further includes: a back cover 151, which extends in the height direction and whose bottom is adapted to be connected with the base 10. The back cover 151 is provided with a first air vent 1511 and a second air vent 1512 at intervals in the height direction, and a second air duct 172 connecting the first air vent 1511 and the second air vent 1512. The first air vent 1511 is located at the bottom end of the back cover 151 and is directly opposite to the cavity outlet 164. The second air vent 1512 is located above the first air vent 1511 and is connected to the inner cylinder.

[0060] Specifically, a rear cover 151 is provided above the base 10. The rear cover 151 extends along the height direction. A first air vent 1511 and a second air vent 1512 are provided at intervals along the extension direction of the rear cover 151. The first air vent 1511 is directly opposite the cavity outlet 164, and the second air vent 1512 is connected to the inner cylinder. During the operation of the impeller 11, the impeller 11 rotates and guides the airflow. The airflow flows through the air outlet 163 to the cavity outlet 164 and into the first air vent 1511. Then, the airflow flows through the second air duct 172 and into the inner cylinder through the second air vent 1512. The rear cover 151 guides the airflow, making it easier to control the airflow between the mounting cavity 103 and the inner cylinder. The rear cover 151 and the base 10 can isolate the impeller 11 from the external space of the clothing processing equipment, reduce the noise generated by the impeller 11, reduce the operating noise of the clothing processing equipment, and improve the user experience.

[0061] According to some embodiments of the present invention, a guide plate 152 is provided in the second air duct 172, and the guide plate 152 is directly opposite to the first air outlet 1511 and is inclined toward the second air outlet 1512.

[0062] Specifically, an air guide plate 152 is inclinedly arranged inside the second air duct 172. The air guide plate 152 is directly opposite the first air outlet 1511 and inclined towards the second air outlet 1512. This allows the airflow to be guided by the air guide plate 152 and flow towards the second air outlet 1512 when it enters the second air duct 172 from the first air outlet 1511. This facilitates the control of the concentrated airflow to the second air outlet 1512 and then to the inner cylinder. This helps to optimize the airflow path and reduce the eddies and turbulence generated by the airflow, thereby reducing noise and energy consumption. By setting the air guide plate 152 inside the second air duct 172, the garment processing equipment can more effectively control the direction and speed of the airflow, which helps to improve the processing efficiency of the garment processing equipment.

[0063] According to some embodiments of the present invention, the garment processing device further includes: a second motor, which is disposed on the base 10 and / or the outer casing 15 and is adapted to drive the inner drum to rotate.

[0064] Specifically, the second motor can be mounted on the base 10, or on the housing 15, or the second motor can be fixed to both the housing 15 and the base 10 to ensure the stability of the second motor. Figure 1 and Figure 2 As shown, a second motor mounting position 18 can be provided on the base 10 to fix the second motor. The second motor drives the cylinder to rotate, and the first motor 131 drives the impeller 11 to rotate. The first motor 131 and the second motor work independently to avoid mutual interference and help reduce the noise of the whole machine.
