[0047] This application proposes a clothing processing device, combined with Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments of the present application, the clothing processing device includes a barrel body (not shown in the figure), an air duct 1000, a first fan 2000, a heating device (not shown in the figure) and a boosting device 3000. The air duct 1000 needs to be connected to the barrel body, and the first fan 2000, the heating device and the boosting device 3000 are respectively arranged in the air duct 1000. The first fan 2000 needs to be connected to the driving device 4000. Driven by the driving device 4000, the first fan 2000 can rotate to drive the airflow along the air duct 1000 and flow toward the barrel body. In the process of the airflow flowing along the air duct 1000, it flows through the heating device and the boosting device 3000. The heating device heats the airflow, and the boosting device 3000 realizes the pressurization of the airflow.

[0048] The first fan 2000 can drive the air flow along the air duct 1000 and input the air flow into the barrel body. The heating device can heat the air flow so that the air flow input into the barrel body has a certain temperature, thereby drying the clothes in the barrel body. On this basis, the boosting device 3000 is set to boost the air flow passing through, so that the air flow finally input into the barrel body has a higher penetration ability on the clothes, which is beneficial for the air flow to reach the center area of ​​the clothes, thereby improving the drying uniformity of the clothes and shortening the drying time, especially for large pieces of clothes. It also has a better drying effect.

[0049] Specifically, the clothing processing equipment can be a dryer (such as a heat pump dryer, a hot air dryer), or a washer-dryer (a washer-dryer that combines washing and drying functions). The following will be explained using a heat pump dryer as an example. The barrel body is a component for accommodating clothes and is generally designed to be placed horizontally. The air duct 1000 is arranged outside the barrel body and needs to be connected to the barrel body. The air duct 1000 is a component for transmitting airflow. The first fan 2000 and the heating device both need to be arranged in the air duct 1000. The heating device is a component for heating airflow. If it is a heat pump dryer, the heating device is the condenser of the heat pump system. If it is a hot air dryer, the heating device is an electric heater. The first fan 2000 needs to be connected to the driving device 4000. The driving device 4000 is a power output component, such as a motor. The connection between the first fan 2000 and the driving device 4000 can be a direct connection or an indirect connection, as long as the driving device 4000 can drive the first fan 2000 to rotate. The first fan 2000 is a component that can form negative pressure and thus draw airflow when rotating. There are many forms, which are not limited here. For example, the first fan 2000 is a multi-blade centrifugal impeller.

[0050] The barrel body, the air duct 1000, the first fan 2000 and the heating device constitute a traditional heat pump dryer structure. When drying clothes, the barrel body rotates (for the rotation of the barrel body, please refer to the relevant technology, which is not an improvement of this application and will not be described in detail), and the clothes are constantly flipped in the barrel body. The driving device 4000 drives the first fan 2000 to rotate. The rotation of the first fan 2000 drives the airflow to be transmitted along the air duct 1000, so that the airflow flows to the barrel body. At the same time, when the airflow flows through the heating device, the heating device can heat the airflow, so that the airflow becomes hot air, that is, the airflow entering the barrel body has a certain temperature, thereby achieving drying of the clothes. It can be understood that the airflow entering the barrel body needs to be discharged after heat exchange with the clothes. It can be discharged directly to the outside world or discharged to the air duct 1000 to form a cycle.

[0051] Generally speaking, if the airflow generated by driving the first fan 2000 only by the driving device 4000 is difficult to penetrate the outside of the clothes to reach the inside of the clothes, which results in poor drying uniformity and a longer drying time. For this reason, in this embodiment, a boosting device 3000 is provided in the air duct 1000, and the boosting device 3000 boosts the airflow passing through it, thereby increasing the wind pressure of the airflow. After the airflow with a higher wind pressure flows into the barrel body, it is more likely to penetrate the outside of the clothes and reach the inside of the clothes, thereby improving the drying uniformity of the clothes and shortening the drying time.

[0052] The supercharging device 3000 can be positioned upstream of the first fan 2000, meaning the airflow flows through the supercharging device 3000 first and then through the first fan 2000. Alternatively, the supercharging device 3000 can be positioned downstream of the first fan 2000, meaning the airflow flows through the first fan 2000 first and then through the supercharging device 3000. If the supercharging device 3000 is positioned upstream of the first fan 2000, the airflow is supercharged as it passes through the supercharging device 3000, and thus already has a high pressure before entering the first fan 2000. Furthermore, the work performed by the first fan 2000 causes the airflow exiting the first fan 2000 to have a higher velocity and pressure. Under these conditions, the airflow can enhance penetration into the clothing, improve drying uniformity, and shorten drying time. Furthermore, after the airflow enters the barrel, moisture on the clothing evaporates and enters the airflow, requiring the airflow to be promptly discharged from the barrel. A higher velocity also facilitates moisture discharge, further shortening drying time. If the boosting device 3000 is arranged downstream of the first fan 2000, when the air flow flows through the first fan 2000, the first fan 2000 works on the air flow, so that the air flow has a certain wind speed and wind pressure, and then the air flow flows through the boosting device 3000 again. The boosting device 3000 further increases the wind pressure of the air flow, so that the air flow reaching the clothes has a higher wind pressure (the wind speed may be lower than the former). The air flow with a higher wind pressure can also improve the penetration into the clothes, thereby improving the drying uniformity and shortening the drying time.

[0053] The following description takes the case where the supercharging device 3000 is disposed upstream of the first fan 2000 as an example.

[0054] Combine Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments of the present application, the boosting device 3000 includes a rectifier fan 3200 and a second fan 3100. The second fan 3100 needs to be connected to the driving device 4000. Under the drive of the driving device 4000, the second fan 3100 can rotate. The rotation of the second fan 3100 can also drive the airflow to flow along the air duct 1000 and flow toward the barrel body. The rectifier fan 3200 is arranged downstream of the second fan 3100. Through the cooperation of the rectifier fan 3200 and the second fan 3100, the airflow is boosted.

[0055] Specifically, the second fan 3100 is a structure that can create a negative pressure when rotating, thereby sucking airflow. The second fan 3100 can be in various forms, which are not limited here. The following description uses the second fan 3100 as an example of a mixed flow impeller. The connection between the second fan 3100 and the driving device 4000 can be a direct connection or an indirect connection, as long as the driving device 4000 can drive the second fan 3100 to rotate. Since the supercharging device 3000 is arranged upstream of the first fan 2000 and the rectifier fan 3200 is arranged downstream of the second fan 3100, that is, the rectifier fan 3200 is located between the second fan 3100 and the first fan 2000 (between the downstream of the second fan 3100 and the upstream of the first fan 2000), when the second fan 3100 rotates, the second fan 3100 sucks airflow and discharges it to the rectifier fan 3200. The rectifier fan 3200 is used to receive the airflow discharged from the second fan 3100 and output it to the first fan 2000.

[0056] When the second fan 3100 rotates, the second fan 3100 rotates to form a negative pressure, thereby sucking in airflow. The second fan 3100 does work on the airflow, thereby accelerating the airflow (the second fan 3100 mainly increases the wind speed of the airflow, and of course it also has a certain effect on the wind pressure of the airflow). The airflow output by the second fan 3100 flows through the rectifying fan 3200. The rectifying fan 3200 can realize the rectification of the airflow. The so-called rectification is to adjust the shape of the airflow, such as adjusting the flow direction of the airflow, thereby achieving the deceleration of the airflow, converting kinetic energy into potential energy, and increasing the wind pressure of the airflow. For example, the rectifying fan 3200 includes a plurality of rectifying blades 3220. When the airflow flows through the rectifying fan 3200, the airflow passes between any two adjacent rectifying blades 3220. During this process, the airflow may encounter obstruction by the rectifying blades 3220 and change direction, thereby decelerating the airflow and converting the kinetic energy of the airflow into potential energy. By such a setting, the airflow is pressurized, so that the airflow leaving the rectifying fan 3200 has a higher wind pressure, and the airflow continues to flow through the first fan 2000. The first fan 2000 does work on the airflow, mainly increasing the wind speed of the airflow (of course, it also has a certain effect on increasing the wind pressure). In this way, the airflow discharged from the first fan 2000 has a higher wind pressure and a higher wind speed. After this part of the airflow is input into the barrel body, it can enhance the penetration of clothes. In particular, the rectifier fan 3200 is designed to be stationary. For example, the rectifier fan 3200 is fixed to a certain structure, and the rectifier fan 3200 is fixed. It can be understood that the stationary here means fixed relative to the second fan 3100. In this way, the rectifier fan 3200 will not rotate under the action of the airflow, which is more conducive to the conversion of kinetic energy into potential energy.

[0057] In some embodiments of the present application, the rectifying fan 3200 has a plurality of rectifying blades 3220, and the second fan 3100 has a plurality of second blades 3120. The rotation direction of the rectifying blades 3220 is designed to be opposite to the rotation direction of the second blades 3120, thereby strengthening the rectification of the airflow flowing through the rectifying fan 3200 and ensuring the boosting effect.

[0058] Specifically, the rotation direction of the second blades 3120 is opposite to that of the rectifying blades 3220. For example, when viewed from the same direction, if the second blades 3120 rotate counterclockwise, the rectifying blades 3220 rotate clockwise. If the second blades 3120 rotate clockwise, the rectifying blades 3220 rotate counterclockwise. Due to the work of the second fan 3100, the airflow forms a certain rotation along the direction of rotation of the second fan 3100 upon leaving the second fan 3100. Therefore, by designing the rotation direction of the rectifying blades 3220 to be opposite to that of the second blades 3120, it is more effective to block and redirect the airflow, thereby ensuring a supercharging effect.

[0059] Combine Figure 2 and Figure 4 As shown, in some embodiments of the present application, the second fan 3100, the rectifying fan 3200, and the first fan 2000 are designed to be coaxially arranged, which can effectively avoid wind loss. Specifically, the airflow flows through the second fan 3100, the rectifying fan 3200, and the first fan 2000 in sequence. By designing the second fan 3100, the rectifying fan 3200, and the first fan 2000 to be coaxial, the airflow does not need to pass through a large distance or make a large turn in the air duct 1000 when passing through the three. This can effectively avoid wind loss of the airflow, so that the airflow input into the barrel still has a high wind pressure and high wind speed. In addition, by designing the second fan 3100, the rectifying fan 3200, and the first fan 2000 to be coaxial, space can be more rationally utilized, and the drive device 4000 can be conveniently placed. For example, the second fan 3100, the rectifying fan 3200, and the first fan 2000 can all be arranged on the base 5100 of the clothing processing device.

[0060] It is understandable that the driving device 4000 connected to the first fan 2000 and the driving device 4000 connected to the second fan 3100 can be two driving devices 4000, that is, one driving device 4000 corresponds to the first fan 2000, and the other driving device 4000 corresponds to the second fan 3100, or a combination of the two. Figure 4 and Figure 5As shown, the driving device 4000 connected to the first fan 2000 and the driving device 4000 connected to the second fan 3100 are implemented by the same driving device 4000, that is, the same driving device 4000 drives the rotation of the first fan 2000 and the second fan 3100. Compared with providing corresponding driving devices 4000 for the first fan 2000 and the second fan 3100 respectively, providing the same driving device 4000 to drive the first fan 2000 and the second fan 3100 can reduce the number of driving devices 4000, save space, and reduce costs.

[0061] The first fan 2000 and the second fan 3100 are connected to the same driving device 4000. The driving device 4000 may have a driving shaft 4100, and the first fan 2000 is installed on the driving shaft 4100 of the driving device 4000 to realize a direct drive connection with the driving device 4000. The driving device 4000 directly drives the first fan 2000 to rotate, and the second fan 3100 is transmission-connected to the first fan 2000. The rotation of the first fan 2000 drives the rotation of the second fan 3100, so that the second fan 3100 and the driving device 4000 realize an indirect drive connection. Alternatively, the second fan 3100 may be installed It is installed on the driving shaft 4100 of the driving device 4000 to achieve a direct drive connection with the driving device 4000. The driving device 4000 directly drives the second fan 3100 to rotate, and the first fan 2000 is transmission-connected to the second fan 3100. The rotation of the second fan 3100 drives the rotation of the first fan 2000, so that the first fan 2000 and the driving device 4000 achieve an indirect drive connection; it is also possible that the first fan 2000 and the second fan 3100 are both installed on the driving shaft 4100, so as to achieve a direct drive connection with the same driving device 4000, and are directly driven to rotate by the driving device 4000.

[0062] The first fan 2000 and the second fan 3100 are driven by the same driving device 4000 as follows: Figure 4 、 Figure 5 、 Figure 7 and Figure 8 As shown, the driving device 4000 has a driving shaft 4100, which passes through the second fan 3100, the rectifier fan 3200 and the first fan 2000. The second fan 3100 and the first fan 2000 need to be fixed to the driving shaft 4100 respectively so that they can be driven to rotate by the driving shaft 4100. In this way, the same driving device 4000 can simultaneously drive the second fan 3100 and the first fan 2000 to rotate, thereby reducing the number of driving devices 4000 and simplifying the structure.

[0063] Specifically, the first fan 2000 has a first central portion 2100 having a first axial hole. For example, the first fan 2000 is a centrifugal impeller, and the centrifugal impeller shown in the figure is a multi-blade centrifugal impeller. The second fan 3100 has a second central portion 3110 having a second axial hole. For example, the second fan 3100 is a mixed flow impeller. A mixed flow impeller can cause the airflow to move both centrifugally and axially. For example, the mixed flow impeller shown in the figure is a turbine. The first fan 2000 is mounted on the drive shaft 4100 through the first axial hole, and the second fan 3100 is mounted on the drive shaft 4100 through the second axial hole. There are many ways to fix the first fan 2000 and the drive shaft 4100, and the second fan 3100 and the drive shaft 4100. For example, the first fan 2000 and the drive shaft 4100 are keyed together by a first metal key 6100, and the second fan 3100 and the drive shaft 4100 are keyed together by a second metal key 6200. In this way, in the direction of rotation, the first fan 2000 and the second fan 3100 are respectively fixed to the drive shaft 4100, so that the drive shaft 4100 can drive the first fan 2000 and the second fan 3100 to rotate.

[0064] It is understood that since the rectifier fan 3200 is disposed between the second fan 3100 and the first fan 2000 and is configured to be stationary, the drive shaft 4100 needs to pass through the rectifier fan 3200. For example, the rectifier fan 3200 has a third central portion 3210 with a third axial hole, through which the drive shaft 4100 passes, and there is a clearance fit between the drive shaft 4100 and the third axial hole. In this case, the rectifier fan 3200 surrounds the drive shaft 4100. When air flows through the rectifier fan 3200, the rectifier fan 3200 can prevent the airflow from rotating around the drive shaft 4100 and generating vortices, thereby reducing wind loss.

[0065] Combine Figure 5As shown, in some embodiments of the present application, the air duct 1000 includes a second air duct 1200, and a pressurizing device 3000 is disposed in the second air duct 1200. Among them, the second air duct 1200 has an upstream flow section 1210 and a downstream flow section 1220. The second fan 3100 is disposed in the upstream flow section 1210, and the rectifying fan 3200 is disposed in the downstream flow section 1220. And the upstream flow section 1210 is designed to be gradually expanding along the air flow direction, and the downstream flow section 1220 is designed to be gradually shrinking along the air flow direction. Thus, a corner is formed between the upstream flow section 1210 and the downstream flow section 1220. The second fan 3100 does work on the air flow, mainly to increase the wind speed of the air flow. After the air flow is discharged, it flows through the corner, and the air flow direction changes under the action of the corner. Thus, it is also beneficial to convert the kinetic energy of the air flow into potential energy. It can be understood that when the air flow leaves the second fan 3100 and enters the first fan 2000, the flow area of the air flow can also be designed to become larger. Thus, it is also beneficial for the air flow to convert kinetic energy into potential energy. After the air flow changes direction when encountering the corner and then continues to flow through the rectifying fan 3200, under the action of the rectifying fan 3200, the kinetic energy is further converted into potential energy. Thus, the air flow is further pressurized to increase the air pressure of the air flow. In particular, when the second fan 3100, the rectifying fan 3200 and the first fan 2000 are coaxially arranged, the gradually shrinking setting of the downstream flow section 1220 easily makes the air outlet end 1221 of the second air duct 1200 align with the air inlet 2200 of the first fan 2000. Thus, it is beneficial to improve the overall efficiency.

[0066] The second fan 3100 is disposed inside the upstream flow section 1210, that is, surrounded by the flow channel wall of the upstream flow section 1210. Therefore, the cooperation between the second fan 3100 and the flow channel wall of the upstream flow section 1210 is particularly important. The minimum distance between the second fan 3100 and the flow channel wall of the upstream flow section 1210 is L, and it needs to satisfy 1.5 mm < L < 2.5 mm. By such setting, the second fan 3100 is made to fit as closely as possible to the flow channel wall of the upstream flow section 1210, ensuring the suction performance of the second fan 3100 for the air flow. It can be understood that since the second fan 3100 needs to rotate, there needs to be a gap between the second fan 3100 and the flow channel wall of the upstream flow section 1210. If the gap is too small, interference is likely to occur between the second fan 3100 and the flow channel wall of the upstream flow section 1210. If the gap is too large, air leakage is likely to occur in this gap, thus affecting the suction performance of the second fan 3100. After a large number of tests by the inventor, the minimum distance L between the second fan 3100 and the flow channel wall of the upstream flow section 1210 is designed to be 1.5 mm to 2.5 mm, for example, L is 1.5 mm, 1.8 mm, 2.0 mm, 2.3 mm or 2.5 mm. By such optimization, the work effect of the second fan 3100 on the air flow is ensured, laying a foundation for subsequent further pressurization.

[0067] The rectifier fan 3200 is configured to remain stationary and can be fixed to the flow passage wall of the downstream flow section 1220. Since the rectifier fan 3200 is disposed within the downstream flow section 1220, it can be fixed to the flow passage wall of the downstream flow section 1220, which reduces the difficulty of installing the rectifier fan 3200. There are various ways to fix the rectifier fan 3200 to the flow passage wall of the downstream flow section 1220, as long as the rectifier fan 3200 can be positioned and installed within the downstream flow section 1220, such as by fastening the rectifier fan 3200 to the flow passage wall of the downstream flow section 1220 with screws.

[0068] Combine Figure 5 As shown, in some embodiments of the present application, the second fan 3100 is a mixed flow rotor. The specific structure of the second fan 3100 includes a second central portion 3110 and second blades 3120 arranged in the second central portion 3110. The number of second blades 3120 is multiple, and the multiple second blades 3120 are arranged along the circumference of the second central portion 3110. Since the second fan 3100 is a mixed flow rotor, the second blades 3120 are radial, and the airflow is accelerated along the second blades 3120 and discharged along the tangential direction, which is conducive to accelerating the airflow and has higher efficiency. In order to adapt to the flow characteristics of the airflow, the second central portion 3110 is designed to be gradually expanded along the airflow direction. The tail of the second blade 3120 (the position away from the second central portion 3110) can be designed to be wavy to reduce noise.

[0069] Combine Figure 5 As shown, in some embodiments of the present application, the rectifying fan 3200 has a third center portion 3210 and rectifying blades 3220 arranged in the third center portion 3210. The number of the rectifying blades 3220 is multiple, and the multiple rectifying blades 3220 are arranged along the circumference of the third center portion 3210. The third center portion 3210 is designed to be gradually tapered along the airflow direction, and cooperates with the downstream flow section 1220 to adapt to the flow characteristics of the airflow.

[0070] In some embodiments of the present application, the air duct 1000 includes a first air duct 1100 and a second air duct 1200, the first air duct 1100 and the second air duct 1200 are connected, the first fan 2000 is arranged in the first air duct 1100, and the boosting device 3000 is arranged in the second air duct 1200. The air flow is transmitted along the air duct 1000 and flows through the second air duct 1200 and the first air duct 1100 in sequence. Since the boosting device 3000 is in the second air duct 1200 to increase the pressure of the air flow, , that is, the airflow flowing out of the second air duct 1200 and entering the first air duct 1100 has a higher wind pressure. In order to avoid wind loss, in this embodiment, the first fan 2000 is designed as a centrifugal wind wheel, and the air outlet end 1221 of the second air duct 1200 extends into the air inlet 2200 of the first fan 2000. If the airflow leaving the second air duct 1200 can quickly enter the first fan 2000 and be worked by the first fan 2000, it will be more conducive to speeding up and pressurizing the airflow.

[0071] Combine Figure 2 and Figure 4As shown, in some embodiments of the present application, the clothing processing device includes a base 5100, a riser 5300, a cover 5400, and a base cover 5200. The base 5100 is the main structural component of the clothing processing device, providing support for the installation of other components of the clothing processing device. When the clothing processing device is installed, the base 5100 is supported on the ground. The base 5100 can be made of metal, plastic, or other materials. For example, the base 5100 can be integrally injection-molded with a plastic material. In order to accommodate different component installation requirements, the base 5100 is generally irregular in shape. The vertical plate 5300 is generally vertical and is a sheet metal component. The vertical plate 5300 is mounted on the base 5100 and fixed relative to the base 5100. The cover 5400 is located on one side (the rear side) of the vertical plate 5300. The cover 5400 and the vertical plate 5300 cooperate to form a first air duct 1100. The first air duct 1100 constitutes a part of the entire air duct 1000. For example, a hole can be opened in the vertical plate 5300, and air can flow out of the hole in the vertical plate 5300 and enter the barrel body. After the base cover 5200 is installed on the base 5100, it cooperates with the base 5100 to enclose a second air duct 1200, which is also part of the entire air duct 1000. For example, the base 5100 has a first area 5110, and the base cover 5200 has a second area 5210. The base cover 5210 covers the base 5100, so that the first area 5110 and the second area 5210 mate, thereby enclosing the second air duct 1200. The drive device 4000 can be mounted to the base 5100. After the booster device 3000 and the first fan 2000 are installed, the booster device 3000 is located in the second air duct 1200, and the first fan 2000 is located in the first air duct 1100. This arrangement facilitates assembly of the various components.

[0072] The first air duct 1100 and the second air duct 1200 are assembled. In order to make the air flow smoothly from the second air duct 1200 to the first air duct 1100, the air duct 1100 is connected to the second air duct 1200. Figure 6 As shown, in some embodiments of the present application, the second air duct 1200 needs to be designed to pass through the vertical plate 5300 from the other side (front side) of the vertical plate 5300 to one side (rear side) of the vertical plate 5300, and the portion of the second air duct 1200 exposed on one side of the vertical plate 5300 is regarded as the air outlet end 1221, that is, a portion of the base 5100 and a portion of the base cover 5200 pass through the vertical plate 5300 and are covered by the cover body 5400, thereby realizing the connection between the first air duct 1100 and the second air duct 1200, ensuring that the airflow flows smoothly from the second air duct 1200 to the first air duct 1100.

[0073] Further, combined with Figure 6As shown, in some embodiments of the present application, since the second air duct 1200 passes through the riser 5300, in order to prevent air leakage between the riser 5300 and the second air duct 1200, a deflector 5500 is provided. The deflector 5500 is connected to one side (the rear side) of the riser 5300. For example, the deflector 5500 surrounds the second air duct 1200 (the air outlet end 1221 thereof) to cover the gap between the second air duct 1200 and the riser 5300, thereby preventing airflow from leaking through the gap. On this basis, the structure of the deflector 5500 can also be optimized so that the deflector 5500 has a guiding effect on the airflow, directing the airflow along the extension direction of the first air duct 1100.

All equivalent structural transformations made based on the contents of the present application specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present application.
