DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application.

It should be understood that the data used in this way can be interchanged where appropriate, so that the implementation of the utility model described here can be implemented in an order other than those illustrated or described here, for example.

[0033] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0034] As mentioned in the above background technology: for the integrated front plate type dryers currently on the market, when they are operated in winter or high-latitude environments, there is a problem that water vapor condenses and flows out along the side wall of the dryer cabinet.

[0035] Because the entire drying air duct cannot be completely sealed, at the beginning of drying, the high-temperature and high-humidity gas overflows along the fittings of the drying air duct, causing the inside of the dryer cabinet to be filled with high-temperature and high-humidity gas. A rapidly increasing temperature difference will appear between the air and the side walls of the dryer cabinet, causing the hot air to encounter the cold side walls of the dryer cabinet, condense into water droplets, and eventually flow to the outside of the dryer cabinet, affecting the user experience.

[0036] Currently, some dryers are equipped with a cooling fan in front of the compressor. Due to limited space on the base, the cooling fan in front of the compressor cannot use a large fan blade structure. As long as the compressor can be cooled, the fan speed does not need to be set too high. Under this prerequisite, the fan air volume is small and can only drive the air flow near the compressor. It cannot form an air path in the entire box, and the improvement of water vapor condensation is limited.

[0037] Therefore, in order to improve or solve the above-mentioned technical problems, the embodiments of the present application provide a fan blade structure of a clothing processing device and a dryer, wherein the fan blade structure of the clothing processing device is provided by setting a drum body and a plurality of fan blades, the drum body is used to be connected to the body of the dryer, and the fan blades are circumferentially spaced on the outer wall of the drum body to form a fan with the axis of the drum body as the rotation axis, and the fan blades are configured to rotate with the drum body to form an air path for heating the side walls of the body between the drum body and the body, so that the gas in the body flows, the side walls of the body are quickly heated up, and the temperature difference between the side walls of the body and the hot air leaked into the body is reduced, thereby reducing water vapor condensation.

[0038] The technical solutions shown in the present application are described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other, and the same or similar contents will not be described repeatedly in different embodiments.

[0039] Please refer to Figure 1An embodiment of the present application provides a fan blade structure of a clothing processing device, including a drum body 100 and a plurality of fan blades 200. The drum body 100 is used to be connected to a housing of a clothes dryer. The fan blades 200 are circumferentially spaced on the outer wall of the drum body 100 to form a fan with the axis of the drum body 100 as the rotation axis. The fan blades 200 are configured to rotate with the drum body 100 to form an air path for heating the side panels of the housing between the drum body 100 and the housing.

[0040] The drum body 100 is rotatably installed in a box, and a driving member for driving the drum body 100 to rotate is provided in the box.

[0041] Exemplarily, a plurality of fan blades 200 are evenly spaced circumferentially arranged on the outer peripheral wall of the drum body 100 , so that when the drum body 100 drives the fan blades 200 to rotate, a stable wind source is formed.

[0042] For example, the height of the fan blade 200 can be adjusted according to the gap between the box and the drum body 100 and the required air volume. Generally, the gap between the box and the drum body 100 is between 5mm-5cm. When the height of the fan blade 200 is greater than the gap between the box and the drum body 100, the volume of the box can be enlarged or the circumference of the drum body 100 can be reduced so that when the drum body 100 rotates, the air volume generated by the fan blade 200 meets the demand.

[0043] By adopting the above technical solution, when the drum body 100 rotates, the drum body 100 drives the fan blades 200 to rotate together, thereby forming an air path between the drum body 100 and a box connected to the drum body 100. The air path can make the gas in the box flow, quickly heat up the side wall of the box, reduce the temperature difference between the side wall of the box and the hot air leaked into the box, and thus reduce water vapor condensation.

[0044] In some embodiments provided in this application, for example, reference Figure 1 and Figure 2 The fan blade 200 is arranged in a long strip shape, and the drum body 100 has connecting parts 110 on two opposite sides along the axial direction thereof, and the opposite ends of the fan blade 200 are respectively connected to the connecting parts 110.

[0045] The drum body 100 has flanges on two opposite sides, and the flanges are extended along the radial direction to form a connecting portion 110 for connecting the fan blades 200 .

[0046] Exemplarily, the two ends of the fan blade 200 can be glued to the connecting part 110, or fixed to the connecting part 110 by fasteners. For example, the two ends of the fan blade 200 have connecting plates, the connecting plates are abutted against the connecting part 110, and the fasteners are screws, and the connecting plates are fixed to the connecting part 110 by screws.

[0047] By adopting the above technical solution, by setting the fan blade 200 as a long strip and the connecting part 110, the opposite ends of the fan blade 200 can be connected to the connecting part 110, so as to facilitate the installation of the fan blade 200 on the drum body 100.

[0048] In some embodiments provided in this application, for example, reference Figure 1 and Figure 2 The connecting portion 110 has a slot 111 , and the end of the fan blade 200 is inserted into the slot 111 .

[0049] Exemplarily, the slot 111 is an embedding slot with one end open. When the fan blade 200 is inserted into the slot 111 , the end of the fan blade 200 abuts against the inner bottom wall of the slot 111 .

[0050] Exemplarily, the slot 111 is a through slot, and the end of the fan blade 200 has a protrusion, which is inserted into the slot 111 , and the end of the fan blade 200 is in contact with the connecting portion 110 .

[0051] By adopting the above technical solution and providing the slot 111 , it is convenient to install the fan blade 200 on the connecting portion 110 .

[0052] In some embodiments provided in this application, for example, reference Figure 1 and Figure 2 The end of the fan blade 200 has a clamping portion 210 , which passes through the slot 111 , and is bent relative to the fan blade 200 and abuts against the connecting portion 110 to fasten the fan blade 200 to the connecting portion 110 .

[0053] The slot 111 is a through slot, and the end of the fan blade 200 passes through the slot 111 .

[0054] Exemplarily, the pressing portion 210 is a pressing plate, which is integrally formed with the fan blade 200 , and the pressing plate can be bent relative to the end of the fan blade 200 .

[0055] By adopting the above technical solution, when the fan blade 200 is installed on the connecting part 110, the end of the fan blade 200 is first inserted into the slot 111. At this time, the clamping part 210 passes through the slot 111, and then the clamping part 210 is bent so that the clamping part 210 abuts against the connecting part 110, so that the fan blade 200 can be stably installed on the connecting part 110, thereby ensuring the stability of the fan blade 200 installed on the connecting part 110.

[0056] In some embodiments provided in this application, for example, reference Figure 1 and Figure 2 The end of the connecting portion 110 away from the drum body 100 has an extension portion 120, and the outer peripheral wall of the drum body 100, the connecting portion 110 and the extension portion 120 form a U-shaped groove 121. The opening of the U-shaped groove 121 is arranged along the axial direction of the drum body 100, and the fan blade 200 is embedded in the U-shaped groove.

[0057] Exemplarily, the openings of the two U-shaped grooves 121 located at opposite ends of the drum body 100 are arranged opposite to each other.

[0058] Exemplarily, the extension portion 120 and the connection portion 110 are integrally bent and formed.

[0059] Exemplarily, the extension portion 120 is parallel to the outer peripheral wall of the drum body 100 , and the distance between the extension portion 120 and the outer peripheral wall of the drum body 100 is greater than the height of the fan blade 200 .

[0060] By adopting the above technical solution and providing the extension portion 120 , the end of the blade 200 can be hidden, thereby preventing the end of the blade 200 from protruding, thereby preventing the flatness of the outer peripheral wall of the drum body 100 from being affected.

[0061] In some embodiments provided in this application, for example, reference Figure 3 The fan blade 200 is arranged in a triangular rhombus shape, the width of the top of the fan blade 200 is smaller than the width of the bottom of the fan blade 200, and the bottom of the fan blade 200 is connected to the outer peripheral wall of the drum body 100.

[0062] Exemplarily, the cross-section of the fan blade 200 along its height direction is triangular.

[0063] Exemplarily, the bottom of the fan blade 200 is connected to the outer peripheral wall of the drum body 100 by adhesive.

[0064] By adopting the above technical solution, by setting the fan blade 200 to a triangular rhombus shape, the contact area between the bottom of the fan blade 200 and the drum body 100 is increased, thereby facilitating the installation of the fan blade 200 on the drum body 100.

[0065] In some embodiments provided in this application, for example, reference Figure 3The outer peripheral wall of the drum body 100 has an embedding groove 130 , and the bottom of the fan blade 200 is embedded in the embedding groove 130 .

[0066] Exemplarily, the embedding groove 130 is integrally formed on the outer peripheral wall of the drum body 100 .

[0067] By adopting the above technical solution and providing the embedding groove 130 , the bottom of the fan blade 200 is embedded in the embedding groove 130 , which facilitates determining the position of the fan blade 200 , thereby facilitating installation of the fan blade 200 on the outer peripheral wall of the drum body 100 .

[0068] In some embodiments provided in this application, for example, reference Figure 3 A connecting piece is provided between the drum body 100 and the fan blade 200, and the fan blade 200 is connected to the drum body 100 through the connecting piece.

[0069] Exemplarily, the connecting member is a screw, which passes through the inner wall of the drum body 100, out of the outer peripheral wall of the drum body 100 and is connected to the bottom of the fan blade 200, so as to install the fan blade 200 on the drum body 100. A sealing ring is provided between the screw and the inner wall of the drum body 100 to ensure the sealing after the screw is installed on the drum body 100.

[0070] By adopting the above technical solution and providing a connecting piece, it is not only convenient to install the fan blade 200 on the outer peripheral wall of the drum body 100, but also improves the stability of the fan blade 200 installed on the outer peripheral wall of the drum body 100.

[0071] In some embodiments provided in the present application, exemplarily, the fan blade 200 is arranged in an arc shape along the direction of its height, and the bending direction of the fan blade 200 is consistent with the rotation direction of the drum body 100.

[0072] By adopting the above technical solution and setting the fan blade 200 to be arc-shaped, not only the air volume of the fan blade 200 can be increased, but also the noise generated by the fan blade 200 during rotation can be reduced.

[0073] An embodiment of the present application further provides a clothes dryer, comprising a housing and a fan blade structure of a clothes processing device according to any one of the above embodiments installed on the housing.
