Description

Technical Field

[0001] This invention belongs to the field of clothing processing technology, and particularly relates to a clothes drying device and control method. Background Art

[0002] In the prior art, a clothes dryer includes a drum and a drying air duct, and a drying flow path is formed between the drum and the drying air duct. The drying air duct is equipped with fan blades, which provide the power for the drying airflow to circulate in the drying flow path. When the drying airflow flows through the drum, it exchanges heat with the clothes, causing the moisture in the clothes to evaporate. However, the fan blades and the drum share a drive device. When the drive device reverses, the high-temperature drying airflow cannot enter the drum, resulting in unstable and low flow rate of the drying airflow, poor drying effect and low drying efficiency.

Detailed Implementation

[0056] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0057] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” used in the embodiments of this invention and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise. “Multiple” generally includes at least two, but does not exclude the inclusion of at least one.

[0058] It should be understood that the term "and / or" as used herein is merely a description of the relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " in this document generally indicates that the associated objects are in an "or" relationship.

[0059] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.

[0060] In existing dryers, the fan blades and drum share a single drive unit. When the drive unit reverses, the high-temperature drying airflow cannot enter the drum, resulting in unstable and low flow rate of the drying airflow, poor drying effect, and low drying efficiency.

[0061] This invention creatively provides a clothes drying device in which a drying air duct and a drum are connected to form a drying flow path. The drying air duct includes an air inlet, an air inlet outlet and a drying air inlet. Each air inlet has a fan blade cavity, and each fan blade cavity contains a drying fan blade. A movable windbreak component is provided at the first air inlet.

[0062] When the first drive device drives M first drying fan blades and drums to rotate forward simultaneously, the wind deflector component opens the corresponding first air inlet; the second drive device drives N second drying fan blades to rotate forward, and the drying airflow can enter the air inlet through all the air inlets and then enter the drum, resulting in a large flow rate.

[0063] When the first drive device drives M first drying fan blades and drums to rotate in reverse simultaneously, or when the first drive device drives M first drying fan blades and drums to stop rotating, the wind baffle assembly closes the corresponding first air inlet; the second drive device drives N second drying fan blades to rotate in the forward direction, and the drying airflow can enter the air inlet through the air inlet other than the first air inlet, and then enter the drum, thereby improving the stability of the drying airflow and ensuring the drying effect.

[0064] Example 1

[0065] like Figures 1 to 7 As shown, this embodiment provides a clothes drying device, which can be a clothes dryer with a standalone drying function, or a clothes processing device with both drying and washing functions; the clothes drying device includes:

[0066] Base 6,

[0067] A roller 11 is rotatably mounted on and above a base 6. A drying air outlet 111 is provided at the opening of the roller 11, and a drying air inlet is provided on the rear wall of the roller 11. Specifically, a front support is provided at the front of the roller 11, and a pick-up / placement opening is formed on the front support. The pick-up / placement opening is connected to the opening of the roller 11 and is used for picking up and placing clothes. A drying air outlet 111 is formed on the side wall of the pick-up / placement opening, and the drying air outlet 111 is connected to the pick-up / placement opening. That is, the drying airflow enters through the rear wall of the roller 11 and exits through the opening of the roller 11.

[0068] A drying air duct connects the drying air inlet and the drying air outlet 111. The drying air duct and the drum 11 are connected to form a drying flow path. The drying air duct includes an air inlet duct 14, a box channel, and an air outlet duct connected in sequence. The air inlet duct 14 is located behind the drum 11 and has an air inlet outlet 123 and multiple air inlets. The air inlet outlet 123 is connected to the drying air inlet. The air inlet outlet 123 is used to deliver drying airflow to the drum 11, and the air inlets are used to deliver drying airflow to the air inlet duct 14. Each air inlet has a fan blade cavity. The air inlet is located at the lower end of the air inlet duct 14, and the air inlet outlet 123 is located at the upper end of the air inlet duct 14. The drying airflow can flow from bottom to top along the air inlet duct 14.

[0069] The unit has multiple drying fan blades, each corresponding to and rotatably mounted within a specific fan blade cavity. The rotation of these blades circulates the drying airflow within the drying path, allowing heat exchange between the airflow and the clothes inside the drum 11, evaporating moisture and achieving drying. The multiple drying fan blades include M first drying fan blades 151 and N second drying fan blades 152. The air inlet corresponding to the first drying fan blade 151 is designated as the first air inlet 121, and the air inlet corresponding to the second drying fan blade 152 is designated as the second air inlet 122. Each first air inlet 121 is equipped with a movable baffle assembly, which can be controlled to open or close the corresponding first air inlet 121. The second air inlet 122 is always open and does not have a baffle assembly.

[0070] The first driving device 3 and the second driving device 4 are respectively. The first driving device 3 can drive M first drying fan blades 151 and drum 11 to rotate forward or reverse simultaneously. That is, the M first drying fan blades 151 and drum 11 have a common driving device. When the drum 11 rotates forward and reverse alternately, the first drying fan blades 151 also rotate forward and reverse alternately. The second driving device 4 can drive N second drying fan blades 152 to rotate simultaneously or independently.

[0071] When the first drive device 3 drives M first drying fan blades 151 and drum 11 to rotate simultaneously, the wind baffle component opens the corresponding first air inlet 121; at this time, the second drive device 4 can drive N second drying fan blades 152 to rotate, and the drying airflow can enter the air inlet 14 through all the air inlets, and then enter the drum 11. The flow rate is large, the drying time is short, the drying airflow and the clothes in the drum 11 are fully in contact, and the drying effect is good.

[0072] When the first drive device 3 drives M first drying fan blades 151 and drum 11 to rotate in reverse simultaneously, or when the first drive device 3 drives M first drying fan blades 151 and drum 11 to stop rotating, the wind baffle assembly closes the corresponding first air inlet 121 to prevent the first drying fan blades 151 from rotating in reverse, thus reducing the drying airflow entering the drum 11. At this time, the second drive device 4 can drive N second drying fan blades 152 to rotate in the forward direction, and the drying airflow can enter the air inlet 14 through the second air inlet 122 and then enter the drum 11, improving the stability of the drying airflow, maintaining the balance of the drying airflow in the drying circuit, ensuring the drying effect, and improving the drying efficiency. It also reduces the mutual interference of multiple drying airflows in the air inlet 14, effectively preventing the "wind grabbing" problem when the first drying fan blades 151 rotate in reverse, and significantly improving the efficiency and energy efficiency of the dryer.

[0073] Where M and N are both positive integers, and M≥1, N≥1; preferably, M=1, N=1.

[0074] There are two ways to drive the movement of the windshield assembly:

[0075] The first configuration involves a drive connection between the first drive device 3 and the wind deflector assembly. The wind deflector assembly is configured such that: when the first drive device 3 drives the drum 11 to rotate forward, the first drive device 3 can drive the wind deflector assembly to open the corresponding first air inlet 121; when the first drive device 3 drives the drum 11 to rotate in reverse or stop rotating, the first drive device 3 can drive the wind deflector assembly to close the corresponding first air inlet 121; that is, when the first drive device 3 drives the drum 11 and N first drying fan blades 151 to rotate forward, it also drives the wind deflector assembly to move, causing the wind deflector assembly to open the corresponding first air inlet 121; when the first drive device 3 drives the drum 11 and N first drying fan blades 151 to rotate in reverse, or when the first drive device 3 drives the drum 11 and N first drying fan blades 151 to stop rotating, the first drive device 3 also drives the wind deflector assembly to move, causing the wind deflector assembly to close the corresponding first air inlet 121.

[0076] The second type: The drying equipment also includes a third drive device, which is connected to the wind deflector assembly. The wind deflector assembly is configured such that: when the first drive device 3 drives the drum 11 to rotate forward, the third drive device can drive the wind deflector assembly to move and open the corresponding first air inlet 121; when the first drive device 3 drives the drum 11 to rotate in reverse or stop rotating, the third drive device can drive the wind deflector assembly to move and close the corresponding first air inlet 121; that is, according to the state of the drum 11 and the N first drying fan blades 151, the third drive device can be controlled to drive the wind deflector assembly to move, so that the first air inlet 121 is opened or closed; wherein, the state of the drum 11 and the N first drying fan blades 151 includes forward rotation, reverse rotation, or stop rotation;

[0077] Preferably, the windshield assembly is driven by the first method.

[0078] The structure and movement of the wind deflector assembly determine whether the wind deflector assembly can smoothly open or close the first air inlet 121. This will be further explained below. The wind deflector assembly includes multiple wind deflector plates 2, which are sequentially arranged along the circumference of the corresponding first air inlet 121. The surface of each wind deflector plate 2 is perpendicular to the centerline of the corresponding first air inlet 121, and each wind deflector plate 2 is slidably disposed at the corresponding first air inlet 121. Preferably, each wind deflector assembly includes 5 to 10 wind deflector plates 2.

[0079] When the first driving device 3 drives multiple baffles 2 to move away from the center line of the corresponding first air inlet 121, the multiple baffles 2 open the corresponding first air inlet 121; the multiple baffles 2 can move simultaneously in a direction away from the center line of the corresponding first air inlet 121, or the multiple baffles 2 can move sequentially in a direction away from the center line of the corresponding first air inlet 121.

[0080] When the first driving device 3 drives multiple baffles 2 to approach the center line of the corresponding first air inlet 121, the multiple baffles 2 close the corresponding first air inlet 121; the multiple baffles 2 can move simultaneously toward the center line of the corresponding first air inlet 121, or the multiple baffles 2 can move sequentially toward the center line of the corresponding first air inlet 121.

[0081] The following example, using M=1 and N=1, further illustrates the driving method of the windshield assembly movement;

[0082] The first driving device 3 is mounted on the base 6 and includes a first driving motor 31, a drum transmission mechanism, and a baffle transmission mechanism. The first driving motor 31 includes a first output shaft 311 and a second output shaft 312. The first output shaft 311 is located at one axial end of the first driving motor 31, and the second output shaft 312 is located at the other axial end of the first driving motor 31. The first output shaft 311 and the drum 11 are connected by the drum transmission mechanism. Specifically, the drum transmission mechanism includes a pulley 32 and a belt 32. The pulley 32 is driven to the first output shaft 311, and the pulley 32 and the drum 11 are connected by the belt 32. When the first output shaft 311 rotates, the pulley 32 drives the drum 11 to rotate through the belt 32. The rotation speed of the drum 11 and the rotation speed of the first drying fan blade 151 can be adjusted according to the actual drying needs. The alternating forward and reverse rotation of the drum 11 can prevent clothes from getting tangled due to the unidirectional rotation of the drum 11.

[0083] Among them, "forward rotation" refers to either clockwise or counterclockwise rotation of the roller 11 when observed from the opening of the roller 11; "reverse rotation" refers to either clockwise or counterclockwise rotation of the roller 11 when observed from the opening of the roller 11.

[0084] The second output shaft 312 has a first output section and a second output section that are spaced apart along the axial direction of the second output shaft 312; the first output section and the first drying fan blade 151 are driven to rotate, and the first drying fan blade 151 can rotate when the first output section rotates; the second output section and the wind deflector assembly are driven to rotate through the wind deflector transmission mechanism, and when the second output section rotates, the wind deflector assembly moves under the action of the wind deflector transmission mechanism, thereby opening or closing the first air inlet duct inlet 121;

[0085] The wind deflector transmission mechanism includes a first state, a second state, and a third state between the first state and the second state; the wind deflector transmission mechanism can switch from the first state to the second state via the third state, or switch from the second state to the first state;

[0086] When the wind deflector transmission mechanism is in the first state, the first drive motor 31 drives the drum 11 and the first drying fan blade 151 to rotate forward, and the wind deflector assembly fully opens the corresponding first air inlet 121.

[0087] When the wind deflector transmission mechanism is in the second state, the first drive motor 31 drives the drum 11 and the first drying fan blade 151 to reverse or stop rotating, and the wind deflector assembly completely seals the corresponding first air inlet 121.

[0088] When the baffle transmission mechanism is in the third state, the first drive motor 31 drives the drum 11 and the first drying fan blade 151 to rotate forward or in reverse, and the baffle assembly partially opens the corresponding first air inlet 121; when the first drive motor 31 drives the drum 11 and the first drying fan blade 151 to rotate forward, the baffle assembly moves away from the center line of the first air inlet 121, and the baffle assembly gradually opens the corresponding first air inlet 121; when the first drive motor 31 drives the drum 11 and the first drying fan blade 151 to rotate in reverse, the baffle assembly moves towards the center line of the first air inlet 121, and the baffle assembly gradually closes the corresponding first air inlet 121.

[0089] Furthermore, the windshield transmission mechanism includes a gear set and a turntable 75. The gear set includes a first gear 71, a second gear 72, and a third gear 73. The first gear 71 is driven to the second output unit, and the second gear 72 and the third gear 73 are connected through a connecting shaft 74. The first gear 71 and the second gear 72 are externally meshed. When the second output unit rotates, the first gear 71 rotates, and the second gear 72 and the third gear 73 rotate synchronously.
