Detailed Implementation

[0023] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the present invention is described in the context of a clothes dryer, those skilled in the art will recognize that the dryer could also be a washer-dryer combo or a garment care machine, etc., as long as the device can provide the function of drying clothes. Those skilled in the art can choose the appropriate application based on their needs.

[0024] It should be noted that in the description of this invention, terms such as "center," "horizontal," "inner," and "outer," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0026] Reference Figure 1 and Figure 2 To address the problems of existing dryers failing to remove hair embedded in the seams of clothing and causing damage to clothing during hair removal, the dryer of this invention includes a drying drum 1 and a hair collection device 2. The drying drum 1 is provided with lifting ribs 11, and the hair collection device 2 includes a hair collector 21 and a collector groove cover 23. The lifting ribs 11 are provided with a collector groove 22, and the hair collector 21 is disposed in the collector groove 22. The hair collector 21 is provided with an adhesive substance, such as an adhesive layer, which can collect hair from the seams of clothing in an adhesive manner. Those skilled in the art can set the adhesive substance as needed, and all such settings should fall within the protection scope of this invention.

[0027] In addition, although Figure 1 As shown, the collector groove 22 is set on the upper surface of the lifting rib 11. However, this is not intended to limit its setting position. The collector groove 22 can also be set on the lower surface or side of the lifting rib 11, etc. Those skilled in the art can set the setting position of the collector groove 22 as needed, and all of them should fall within the protection scope of the present invention.

[0028] The advantages of the above-described configuration are as follows: The dryer of the present invention uses the hair collector 21 to collect hair that is not easily shed by airflow from the gaps in clothing through an adhesive method, which can also reduce damage to clothing and thus improve the user experience. Specifically, the present invention provides a collector tank cover 23 on the collector tank 22 to open and close the opening of the collector tank 22. When the collector tank cover 23 is open, the adhesive substance of the hair collector 21 is exposed, which can remove hair from the clothes in the drying drum 1. When the collector tank cover 23 is closed, the adhesive substance of the hair collector 21 is not exposed, and the clothes in the drying drum 1 are not removed. The user can open and close the collector tank cover 23 as needed, so that the user can decide the timing and time of hair removal according to their needs. On the basis of reducing damage to clothing through an adhesive method, the contact time between the hair collector 21 and the clothing is controlled by the collector tank cover 23 to further prevent damage to the clothing.

[0029] Continue to refer to Figure 1 and Figure 2 In one possible implementation, the dryer includes a drying drum 1 and a hair collection device 2. The drying drum 1 is provided with lifting ribs 11. The hair collection device 2 includes a hair collector 21 and a collector groove cover 23. The lifting ribs 11 are provided with a collector groove 22. The hair collector 21 includes an adhesive roller 211 and a roller central shaft 212. The adhesive roller 211 is disposed in the collector groove 22 and is rotatably disposed on the roller central shaft 212. The end of the roller central shaft 212 is disposed on the inner wall of the collector groove 22. The outer surface of the adhesive roller 211 is provided with a plurality of rounded protrusions 213. The adhesive substance adheres to the protrusions 213. The protrusions 213 can increase the friction and contact area between the adhesive roller 211 and the clothes, which will not cause damage to the clothes and improve the hair removal effect.

[0030] Preferably, the two ends of the roller central shaft 212 are respectively set on the inner walls of the two opposite sides of the collector groove 22, so that when the clothes rotate with the dryer drum 1, the adhesive roller 211 rolls and contacts the clothes, reducing the friction between the clothes and the clothes, and making the adhesive roller 211 evenly stick to all parts of the clothes, thereby enhancing the lint removal effect.

[0031] Alternatively, unlike the hair collector 21 in the above embodiments, in another embodiment, the adhesive roller 211 and the roller shaft are fixedly connected, and the adhesive roller 211 and the roller shaft rotate together. Specifically, the hair collector 21 includes an adhesive roller 211 and a roller shaft, the adhesive roller 211 being fixedly mounted on the roller shaft, and the roller shaft being rotatably mounted on the inner wall of the collector groove 22. Preferably, the two ends of the roller shaft are rotatably mounted on the two opposite inner walls of the collector groove 22.

[0032] Furthermore, the dryer includes a first elastic element, a first electromagnetic element, and a second electromagnetic element. Preferably, the first elastic element is a torsion spring, and both the first and second electromagnetic elements are electromagnets. The collector tray cover 23 and the lifting rib 11 are connected by the torsion spring. The first electromagnetic element is disposed on the collector tray cover 23, and the second electromagnetic element is disposed on the lifting rib 11. When the collector tray cover 23 closes the collector tray 22, the two electromagnetic elements are energized, and the first and second electromagnetic elements attract each other, tightening the torsion spring. When the collector tray cover 23 needs to be opened, the electromagnetic elements are de-energized, the magnetic force between the first and second electromagnetic elements disappears and they separate, and the collector tray cover 23 is popped open by the elastic force of the torsion spring, thus smoothly opening the collector tray cover 23. After the dryer finishes running, the collector tray cover 23 is manually closed, and the first and second electromagnetic elements are energized and attracted again. The collector tray cover 23 is opened for the next lint removal cycle.

[0033] Alternatively, in another embodiment of the drive collector trough cover 23 opening and closing, refer to Figure 2 The dryer also includes a first tray cover drive device. The drive shaft of the first tray cover drive device is connected to the collector tray cover 23 to drive the collector tray cover 23 to open and close. Specifically, the collector tray cover 23 is provided with a rotating shaft, which is rotatably mounted on the lifting rib 11. Preferably, the first tray cover drive device is a motor, which is connected to the rotating shaft to drive the rotating shaft to rotate. When the motor rotates, it drives the collector tray cover 23 to rotate forward and backward to open and close the collector tray 22, so as to expose or conceal the sticky roller 211. The first tray cover drive device can also be a hydraulic motor or a pneumatic motor, etc. Those skilled in the art can set it themselves, as long as it can make the collector tray cover 23 rotate to open and close.

[0034] In addition to being opened and closed by rotation, the collector tray cover 23 can also be opened and closed by sliding. Specifically, the dryer also includes a transmission component. The first tray cover drive device is connected to the collector tray cover 23 through the transmission component. For example, the transmission component is a gear and a rack. The rack is set on the collector tray cover 23, and the first tray cover drive device is connected to the gear to drive the gear to rotate. When the gear rotates, it meshes with the rack, causing the collector tray cover 23 to move back and forth to open and close. Alternatively, the transmission component can also be a lead screw and a nut that cooperates with the lead screw. The nut is set on the collector tray cover 23, and the first tray cover drive device is rotatably connected to the lead screw. When the lead screw rotates, the nut moves on the lead screw, thereby driving the collector tray cover 23 to move back and forth on the collector tray 22. However, it should be noted that the first tray cover drive device can also be a hydraulic cylinder or a pneumatic cylinder, etc. The piston rod of the hydraulic cylinder or pneumatic cylinder can be directly connected to the collector tray cover 23, so that the piston rod drives the collector tray cover 23 to move back and forth on the collector tray 22 to open and close the collector tray 22. Alternatively, a hydraulic cylinder or pneumatic cylinder or other driving device can be connected to the collector tank cover 23 via a transmission component, and the collector tank cover 23 can be moved to open and close by driving the transmission component. Therefore, the present invention does not impose any restrictions on the specific type of the first tank cover driving device. Those skilled in the art can set the first tank cover driving device as needed, as long as it can drive the collector tank cover 23 to open and close the collector tank 22, and all such settings fall within the protection scope of the present invention.

[0035] However, it should be noted that the opening method of the collector trough cover 23 is not limited to the above-mentioned opening method. It can also be other opening methods. Those skilled in the art can set the opening method of the collector trough cover 23 as needed, as long as it can open and close, and all such methods should fall within the protection scope of this invention. Secondly, the number of hair collecting devices 2 can be one or more. Those skilled in the art can set the number of hair collecting devices 2 as needed. Furthermore, the shape of the hair collector 21 is not limited to a cylindrical roller. It can also be polygonal or semi-circular, etc. It can also omit the central shaft 212 or the rotating shaft. The hair collector 21 is non-rotatably disposed in the collector trough 22. Those skilled in the art can set the structure of the hair collector 21 as needed, and all such methods should fall within the protection scope of this invention. Furthermore, the shape of the collector trough 22 and the collector trough cover 23 that cooperates with the collector trough 22 can be circular, square, triangular, etc. Those skilled in the art can set the shape of the collector trough 22 and the collector trough cover 23 as needed.

[0036] Furthermore, the dryer also includes a hair removal device (not shown in the figure), which includes a soft-bristled roller brush and a roller brush groove cover. A roller brush groove is provided on the lifting rib 11, the soft-bristled roller brush is rotatably disposed in the roller brush groove, and the roller brush groove cover is openable and closable disposed on the roller brush groove. Optionally, the hair removal device can be configured such that, except for the soft-bristled roller brush, which differs from the hair collection device 21, all other components are the same as those of the hair collection device 2.

[0037] The hair removal device also includes a central shaft for a roller brush, on which a soft-bristled roller brush is rotatably mounted, with one end of the central shaft positioned on the inner wall of the roller brush groove. Alternatively, in another embodiment, the hair removal device includes a rotating roller brush shaft, on which a soft-bristled roller brush is mounted, with one end of the rotating roller brush shaft rotatably mounted on the inner wall of the roller brush groove. Preferably, the two ends of the rotating roller brush shaft are rotatably mounted on two opposite inner walls of the roller brush groove.

[0038] Furthermore, the hair removal device includes a second elastic element, a third electromagnetic element, and a fourth electromagnetic element. Preferably, the second elastic element is a torsion spring, and the third and fourth electromagnetic elements are both electromagnets. The brush groove cover and the lifting rib 11 are connected by the torsion spring. The third electromagnetic element is disposed on the brush groove cover, and the fourth electromagnetic element is disposed on the lifting rib 11. When the brush groove cover closes the brush groove, the electromagnetic elements are energized, and the third and fourth electromagnetic elements attract each other, locking the brush groove cover and the lifting rib 11, and the torsion spring tightens. When the brush groove cover needs to be opened, the electromagnetic elements are de-energized, the magnetic attraction between the third and fourth electromagnetic elements disappears and separates, and the brush groove cover is springed open under the elastic force of the torsion spring, thus smoothly opening the brush groove cover. After the dryer finishes running, the brush groove cover is manually closed, and the third and fourth electromagnetic elements are energized again to attract and lock, so that the brush groove cover can be opened for the next hair removal.

[0039] Alternatively, in another embodiment of the drive mechanism for opening and closing the brush slot cover, the dryer further includes a second slot cover drive device. This second drive device is connected to the brush slot cover via a transmission connection to drive the brush slot cover to open and close the brush slot. Specifically, the brush slot cover is provided with a rotating shaft, which is rotatably mounted on the lifting rib 11. Preferably, the second slot cover drive device is a motor, which is connected to the rotating shaft via a transmission connection to drive the rotating shaft to rotate. When the motor rotates, it drives the brush slot cover to rotate in both directions to open and close the brush slot, thus exposing or concealing the soft brush bristles. The first slot cover drive device can also be a hydraulic motor or a pneumatic motor, etc., which can be customized by those skilled in the art, as long as it enables the brush slot cover to rotate and open / close.

[0040] In addition to rotating, the brush tray cover can also be opened and closed by sliding. Furthermore, the dryer includes a transmission component. The second tray cover drive device is connected to the brush tray cover via this transmission component. For example, the transmission component could be a gear and a rack meshing with it. The rack is mounted on the brush tray cover, and the second tray cover drive device is connected to the gear to drive it to rotate. When the gear rotates, it meshes with the rack, causing the brush tray cover to move back and forth to open and close. Alternatively, the transmission component could be a lead screw and a nut meshing with it. The nut is mounted on the brush tray cover, and the second tray cover drive device is connected to the lead screw. When the lead screw rotates, the nut moves on the lead screw, thus driving the brush tray cover to move back and forth. However, it should be noted that the second tray cover drive device could also be a hydraulic cylinder or a pneumatic cylinder. The piston rod of the hydraulic cylinder or pneumatic cylinder can be directly connected to the brush tray cover, causing the piston rod to drive the brush tray cover to move back and forth on the brush tray to open and close. Alternatively, a hydraulic cylinder or pneumatic cylinder can be connected to the brush groove cover via a transmission component, and the brush groove can be moved horizontally to open and close by driving the transmission component. Therefore, this invention does not impose any restrictions on the specific type of the second groove cover driving device. Those skilled in the art can configure the second groove cover driving device as needed, as long as it can drive the brush groove cover to open and close the brush groove, and all such configurations fall within the protection scope of this invention.

[0041] However, it should be noted that the opening method of the roller brush groove cover is not limited to the aforementioned driving method; other opening methods are also possible. Those skilled in the art can set the opening method of the roller brush groove cover as needed, and all such methods should fall within the protection scope of this invention. Furthermore, the number of hair-cleaning devices can be one or more; those skilled in the art can set the number of hair-cleaning devices as needed. Secondly, the shape of the soft-bristled roller brush is not limited to a cylindrical shape; it can also be polygonal or semi-circular, etc. Those skilled in the art can set the structure of the soft-bristled roller brush as needed, and all such methods fall within the protection scope of this invention. Moreover, the shape of the roller brush groove and the roller brush groove cover that cooperates with the roller brush groove can be circular, square, triangular, etc. Those skilled in the art can set the shape of the roller brush groove and the roller brush groove cover as needed.

[0042] Furthermore, the first and second elastic elements can be torsion springs, or other elastic elements such as elastic rubber and compression springs. Those skilled in the art can select and set the type of elastic element as needed, as long as it can spring up the collector trough cover 23 and the roller brush trough cover, and all should fall within the protection scope of this invention. It should also be noted that the first electromagnetic element, second electromagnetic element, third magnetic element, and fourth magnetic element can be electromagnets or other magnetic materials, and those skilled in the art can set them as needed.

[0043] The above-mentioned dryer removes lint in the following way:

[0044] When the roller brush trough cover is opened, the soft-bristled roller brush rolls with the clothes, and the bristles sweep out the hair from the gaps in the clothes, so that the hair floats on the surface of the clothes. Then the roller brush trough cover is closed, the collector trough cover 23 is opened, and the adhesive roller 211 rolls with the clothes to contact them, so as to stick the hair on the clothes to the surface of the adhesive roller 211. After the hair removal is completed, the collector trough cover 23 is closed.

[0045] In summary, this invention uses a rotatable adhesive roller 211 to evenly adhere hair to clothing, removing hair from crevices. Furthermore, by controlling the opening and closing time of the collector cover 23, the duration of the lint removal operation can be controlled, preventing damage to clothing from prolonged lint removal. Even further, before the adhesive roller 211 adheres to the clothing, the brush cover can be opened, allowing a soft-bristled brush to sweep out hair from crevices before the adhesive roller 211 adheres to it, further improving the lint removal effect. Additionally, to protect the adhesive material on the adhesive roller 211 from high temperatures that could cause it to detach or degrade, the lint removal operation can be performed when the air temperature inside the drying drum 1 is lower. This improves lint removal efficiency, protects the adhesive material, and ensures better adhesion and lint removal at slightly lower air temperatures.

[0046] As described in the first paragraph of this section, the above embodiments are merely used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0047] In addition, the present invention also provides a control method for a clothes dryer, wherein the clothes dryer is the clothes dryer described in any of the above embodiments.

[0048] Specifically, a temperature sensor is installed inside the clothes dryer 1. Preferably, the temperature sensor is installed inside the collector trough 22 and is used to detect the air temperature inside the clothes dryer 1.

[0049] Reference Figure 2 The control method for a clothes dryer includes the following steps:

[0050] Step S100: Obtain the air temperature inside the dryer;

[0051] The corresponding steps are executed by measuring the air temperature inside the dryer drum 1 obtained by the temperature sensor. Specifically, when the air temperature inside the dryer drum 1 is lower than a preset threshold, step S200 is executed. Although this embodiment is described by setting a temperature sensor in the collector slot 22, the temperature sensor can also be set at the air outlet of the air duct, and the temperature of the air outlet of the dryer drum 1 can be detected. Alternatively, the temperature sensor can be set on the lifting rib 1 at a position other than the collector slot 22. Therefore, the present invention does not impose any restrictions on the method of obtaining the air temperature inside the dryer drum 1, as long as the detected temperature value can reflect the temperature of the air inside the dryer drum 1. Those skilled in the art can set it as needed.

[0052] Step S200: When the air temperature inside the dryer is lower than the preset threshold, control the collector tank cover 23 to open.

[0053] When the air temperature inside the dryer drum 1 is lower than a preset threshold, the collector tray cover 23 is opened. For example, the collector tray cover 23 can be opened by controlling a first tray cover drive device connected to it, or the first and second electromagnetic components can be de-energized to cause the collector tray cover 23 to pop open. After the dryer finishes running, the collector tray cover 23 is manually closed, and the first and second electromagnetic components are re-energized to attract the hair. The collector tray cover 23 is opened again for the next hair removal cycle. When the air temperature inside the dryer drum 1 is lower than the preset threshold, the adhesive effect of the sticky substance on the hair collector 21 is optimal. Opening the tray cover at this time improves the hair removal effect and efficiency. When the air temperature inside the dryer drum 1 is higher than the preset threshold, the sticky substance on the hair collector 21 may become ineffective or detach due to the high temperature. The hair removal effect and efficiency are relatively low at this time. Therefore, when the air temperature inside the dryer drum 1 is higher than the preset threshold, the collector tray cover 23 remains closed, and no hair removal operation is performed.

[0054] like Figure 3 As shown, a possible implementation of the control method for the dryer of the present invention will be described below.

[0055] Specifically, the control method includes the following steps:

[0056] Step S301: Receive the garment lint removal instruction.

[0057] The lint removal command can be: a command sent by the user through pressing a button on the dryer or through a mobile app or other terminal device; or a command sent after the dryer has completed a certain program, for example, automatically sending a lint removal command when the drying program is finished. Once the lint removal command is sent, the dryer receives it.

[0058] Step S302: Reduce the air outlet temperature of the dryer's air duct.

[0059] Upon receiving the lint removal command, the air outlet temperature of the dryer's air duct is lowered so that the air duct blows cold air into the drying drum 1. This lowers the air temperature inside the drying drum 1 and causes the lint on the clothes to float up from the gaps and be easily caught by the lint collector 21.

[0060] Step S303: Obtain the air temperature inside the dryer drum;

[0061] Step S304: Determine if the air temperature inside the dryer is lower than a preset threshold. If yes, proceed to step S305; otherwise, proceed to step S303.

[0062] Step S305: Control the opening of the roller brush groove cover for a first preset time;

[0063] Step S306: Control the collector tank cover to open for a second preset time.

[0064] When the air temperature inside the dryer drum 1 is low, first control the roller brush trough cover to open, and the soft-bristled roller brush will sweep the hair in the gaps of the clothes, causing the hair to float to the surface of the clothes. Then control the collector trough cover 23 to open, and the sticky substance on the hair collector 21 will collect the hair to remove hair from the clothes.

[0065] It should be noted that the soft-bristled roller brush and the hair collector 21 can work simultaneously or alternately. For example, the roller brush cover can be opened and closed after a first preset time, and the collector cover 23 can be opened and closed after a second preset time. These two steps are performed alternately. Therefore, the present invention does not impose any restrictions on the opening time of the roller brush cover and the opening time of the collector cover 23. Those skilled in the art can set them as needed.

[0066] It should be noted that the above embodiments are merely used to illustrate the principles of the present invention and are not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above structure so that the present invention can be applied to more specific application scenarios.

[0067] Furthermore, although the above embodiments are described in terms of receiving a lint removal command and performing related control according to the lint removal command, this is not intended to limit the scope of protection of the present invention. For example, the present invention may also not send a lint removal command, but automatically open the roller brush groove cover and the collector groove cover 23 when the air temperature inside the dryer drum 1 is detected to drop to a threshold. These alternative embodiments are all within the scope of protection of the present invention. Those skilled in the art will understand that the aforementioned dryer also includes other known structures, such as processors, controllers, and memories. These memories include, but are not limited to, random access memory (RAM), flash memory, read-only memory (ROM), programmable read-only memory (PROM), volatile memory, non-volatile memory, serial memory, parallel memory, or registers. Processors include, but are not limited to, CPLD / FPGA, DSP, ARM processors, and MIPS processors. To avoid unnecessarily obscuring the embodiments of this disclosure, these known structures are not shown in the accompanying drawings.

[0068] Although the steps in the above embodiments are described in the above order, those skilled in the art will understand that in order to achieve the effect of this embodiment, different steps do not need to be executed in such an order, and they can be executed simultaneously (in parallel) or in a reverse order.

[0069] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments.
