[0047] Existing clothing processing equipment has an unreasonable door structure design, which not only poses a risk of door glass being easily broken, but also makes it very easy for water to accumulate and mold to form at the sealing ring.
[0048] Different from the prior art, an embodiment of the present invention provides a linkage device and a clothes processing device including the same.
[0049] The linkage device provided in an embodiment of the present invention is used for a double-door device, which includes an inner door and an outer door. The linkage device includes: a linkage mechanism, including a shell connected to the outer door, a cam pivotally connected to the shell, and a first latch movably mounted on the shell; a baffle assembly pivotally connected to the shell and transmission connected to the cam; a connecting rod connected to the inner door; wherein the baffle assembly is suitable for rotating along a first rotation direction when pushed inward and driving the cam to rotate along a second rotation direction opposite to the first rotation direction, the cam is suitable for abutting against the first latch when rotating along the second rotation direction and driving it to move toward the connecting rod, and the first latch is suitable for connecting with the connecting rod when moving to connect the inner door with the outer door.
[0050] In the technical solution provided in the embodiment of the present invention, the outer door and the inner door can be connected only by pushing the baffle inward, and when the outer door and the inner door are connected, the two can be opened at the same time only by pulling the outer door outward or the two can be closed at the same time only by pushing the outer door inward. The operation is simple, convenient, and saves time and effort.
[0051] Furthermore, when the outer door is disconnected from the inner door, a certain distance can be maintained between the outer door and the inner door, thereby preventing the movement of the inner drum during operation of the clothing processing device from affecting the stability of the outer door and the front panel of the box.
[0052] Furthermore, the door glass can be installed on the inner door, and the inner door can be hinged to the outer barrel, so that the door glass has a smaller thickness and a simpler shape and can be coated with an explosion-proof film on its surface to reduce the risk of the door glass being broken.
[0053] Furthermore, the first door glass can be installed on the inner door, and the first sealing ring can be installed on the inner side of the inner door and engaged with the outer periphery of the first door glass, so that when the inner door is closed, the sealing ring is squeezed by the outer barrel in the normal direction and is not easy to accumulate water or mold.
[0054] To facilitate description of the linkage device and clothing processing apparatus provided by embodiments of the present invention, some of the accompanying drawings illustrate front and rear directions, as well as exterior and interior directions. The front and rear directions are defined based on the perspective of the linkage device and clothing processing apparatus facing the user during normal use. "Front" refers to the direction in which the linkage device and clothing processing apparatus face the user, and "rear" represents the direction opposite to "front." Exterior corresponds to the "front" direction, and interior corresponds to the "rear" direction. The front and rear directions, as well as exterior and interior directions, are provided solely to facilitate description of the technical solutions of the embodiments of the present invention and do not constitute a restrictive interpretation of these technical solutions.
[0055] In order to make the purpose, features and beneficial effects of the embodiments of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0056] Reference Figures 1 to 9 An embodiment of the present invention provides a linkage device 10 for a double-door device. The double-door device includes an inner door 100 and an outer door 200. The linkage device 10 is used to connect or disconnect the inner door 100 and the outer door 200. The linkage device 10 includes a linkage mechanism 300 connected to the outer door 200, a baffle assembly 400, and a connecting rod 500 connected to the inner door 100.
[0057] Specifically, the linkage mechanism 300 includes a housing 310 connected to the outer door 200, a cam 320 pivotally coupled to the housing 310, and a first latch 331 movably mounted within the housing 310. The baffle assembly 400 is pivotally coupled to the housing 310 and drivingly coupled to the cam 320. When pushed inward, the baffle assembly 400 rotates in a first rotational direction (e.g., clockwise), driving the cam 320 to rotate in a second rotational direction (e.g., counterclockwise) opposite the first rotational direction. When rotating in the second rotational direction, the cam 320 abuts against the first latch 331 and drives the first latch 331 toward the connecting rod 500. The first latch 331 connects with the connecting rod 500 when it moves toward the connecting rod 500, thereby coupling the inner door 100 with the outer door 200.
[0058] In a specific implementation, the outer door 200 may include a front cover 210 and a rear cover 220 connected front to back. The front cover 210 and the rear cover 220 are respectively provided with a first opening 211 and a second opening 221 suitable for the baffle assembly 400 to pass through.
[0059] The baffle assembly 400 includes a baffle 410 and a transmission member 420 connected to each other. The transmission member 420 sequentially passes through the first opening 211 and the second opening 221 and is pivotally connected to the housing 310 of the linkage mechanism 300. The baffle 410 is adapted to cover the first opening 211 and, when pushed inward, drives the transmission member 320 to rotate relative to the housing 310 of the linkage mechanism 300 in a first rotational direction (e.g., clockwise).
[0060] The outer door front cover 210 further includes a handle 212 disposed adjacent to the first opening 211. The handle 212 is adapted to be pushed inward to close the inner door 100 and the outer door 200, and to be pulled outward to open the inner door 100 and the outer door 200.
[0061] The housing 310 of the linkage mechanism 300 includes a bottom wall 312 adapted to mount a transmission member 420 and a cam 320. Specifically, the transmission member 420 and the cam 320 can each be connected to the bottom wall 312 via a pivot axis. For example, the transmission member 420 is connected to the bottom wall 312 of the housing 310 via a first pivot axis 301 and can rotate relative to the housing 310 about the first pivot axis 301; the cam 320 is connected to the bottom wall 312 of the housing 310 via a second pivot axis 302 and can rotate relative to the housing 310 about the second pivot axis 302.
[0062] The linkage mechanism 300 includes a gear 350 fixedly connected to the cam 320. The transmission member 420 is provided with teeth 421. The teeth 421 engage with the gear 350 to achieve a transmission connection between the baffle assembly 400 and the cam 320. Thus, when the baffle assembly 400 is pushed inward and rotated about the first pivot axis 301 in a first rotational direction (e.g., clockwise), it is adapted to drive the cam 320 to rotate about the second pivot axis 302 in a second rotational direction (e.g., counterclockwise).
[0063] The housing 310 of the linkage mechanism 300 further includes a side wall 313 connected to the bottom wall 312. The side wall 313 is provided with a slot 314. The first locking pin 331 passes through the slot 314 and is adapted to be abutted by the cam 320 when the cam 320 rotates in the second rotational direction (e.g., counterclockwise) about the second pivot axis 302 to move toward the connecting rod 500. When moving toward the connecting rod 500, the first locking pin 331 is connected to the connecting rod 500 to connect the inner door 100 with the outer door 200.
[0064] The housing 310 of the linkage mechanism 300 further includes a connecting member 311 fixedly connected to the bottom wall 312 and / or the side wall 313. The linkage mechanism 300 can be pivotally connected to the outer door 200 via the connecting member 311. For example, the connecting member 311 can be connected to the inner side of the outer door front cover 210 via the third pivot axis 303. This allows the linkage mechanism 300 to be pivotally connected to the outer door 200, i.e., the linkage mechanism 300 can rotate relative to the outer door 200 about the third pivot axis 303.
[0065] Accordingly, the connecting rod 500 is pivotally connected to the inner door 100. For example, the connecting rod 500 can be connected to the inner door rear cover 120 via a fourth pivot axis 501. Thus, when the inner door 100 and the outer door 200 are connected and the outer door 200 is pulled outward, the connecting rod 500 is adapted to rotate with the outer door 200 through the linkage mechanism 300 and open the inner door 100.
[0066] The connecting rod 500 includes a socket 510 for connecting with the first latch 331. The first latch 331 is adapted to be inserted into the socket 510 when moving toward the connecting rod 500 to connect with the connecting rod 500.
[0067] In some preferred specific examples, the socket 510 of the connecting rod 500 can have a size and shape that matches the first pin 331, so that the first pin 331 can be tightly inserted into the socket 510, thereby increasing the stability of the connection between the first pin 331 and the connecting rod 500.
[0068] A torsion spring 700 is further provided between the connecting rod 500 and the inner door 100. The torsion spring 700 is adapted to maintain the stability of the connecting rod 500 when the first latch 331 moves toward the connecting rod 500 to be inserted into the insertion hole 510.
[0069] By adopting the technical solution provided by the embodiment of the present invention, the outer door 200 and the inner door 100 can be connected simply by pushing the baffle 410 inward. Specifically, when the baffle 410 is pushed inward, the transmission member 420 connected to the baffle 410 rotates about the first pivot axis 301 in a first rotation direction (e.g., clockwise) and drives the cam 320 to rotate about the second pivot axis 302 in a second rotation direction (e.g., counterclockwise). When the cam 320 rotates about the second pivot axis 302 in the second rotation direction (e.g., counterclockwise), it abuts against the first lock pin 331 in the housing 310 and drives the first lock pin 331 to move toward the connecting rod 500. When the first lock pin 331 moves toward the connecting rod 500, it can be inserted into the insertion hole 510 to connect with the connecting rod 500. Since the connecting rod 500 is connected to the inner door 100 and the housing 310 of the linkage mechanism 300 is connected to the outer door 200 , the outer door 200 and the inner door 100 can be connected when the first lock pin 331 is connected to the connecting rod 500 .
[0070] In this embodiment of the present invention, the linkage mechanism 300 may further include an elastic pin 340 fixed to the cam 320 and rotatable with the cam 320. The housing 310 may further include a retaining slot 315 disposed on the side wall 313. The elastic pin 340 is adapted to abut against the side wall 313 and be compressed as the cam 320 rotates, and to at least partially release the compression when the cam 320 rotates into the retaining slot 315 of the side wall 313 and extend into the retaining slot 315, thereby restricting the rotation of the cam 320.
[0071] In this way, when the first lock pin 331 is inserted into the socket 510 to connect the connecting rod 500 to connect the outer door 200 with the inner door 100, the elastic pin 340 can be extended into the slot 315 of the shell 310 to limit the rotation of the cam 320 to ensure the stability of the connection between the inner door 100 and the outer door 200.
[0072] The linkage device 10 may further include a resetter 600 extending from the outside of the housing 310 to the slot 315. The resetter 600 is adapted to abut against the elastic pin 340 when the elastic pin 340 rotates to the slot 315 to keep the elastic pin 340 compressed, to be offset from the slot 315 when the outer door 200 is pulled outward so that the elastic pin 340 is at least partially released and extends into the slot 315, and to abut against the elastic pin 340 when the outer door 200 is pushed inward so that the elastic pin 340 is compressed and withdraws from the slot 315.
[0073] In this way, when the outer door 200 is pushed inward, the elastic pin 340 can be compressed by the resetter 600 and withdrawn from the locking groove 315, thereby releasing the restriction on the rotation of the cam 320.
[0074] The linkage mechanism 300 further includes a first spring 332 connected between the housing 310 and the first latch 331. The first spring 332 is adapted to be compressed when the cam 320 drives the first latch 331 to move, and at least partially release the compression when the elastic pin 340 exits the slot 315, causing the first latch 331 to move away from the connecting rod 500, thereby disengaging from the connecting rod 500 and driving the cam 320 to rotate in the opposite direction, thereby restoring the baffle assembly 400.
[0075] In this way, when the restriction on the rotation of the cam 320 is released, the first spring 332 can at least partially release the compression so that the first lock pin 331 moves away from the connecting rod 500 and disengages from the connecting rod 500, thereby disconnecting the outer door 200 and the inner door 100.
[0076] In a specific embodiment, the first spring 332 is fixed to the bottom wall 312 or the side wall 313 of the housing 210. The first locking pin 331 can be located above the first spring 332 relative to the bottom wall 312 and fixedly connected to the first spring 332. The first locking pin 331 is adapted to be abutted by the cam 320 when the cam 320 rotates in the second rotational direction (e.g., counterclockwise), thereby moving toward the connecting rod 500 and compressing the first spring 332. The first spring 332 is adapted to be driven by the first locking pin 331 to rotate about the second pivot axis 302 in the first rotational direction (e.g., clockwise) when the elastic pin 340 exits the retaining slot 315 to release the rotation restriction on the cam 340. The compression is at least partially released, causing the first locking pin 331 to move away from the connecting rod 500 and disengage from the connecting rod 500.
[0077] When the cam 320 rotates around the second pivot axis 302 in a first rotation direction (for example, clockwise), the transmission member 420 connected to the cam 320 is suitable for being driven by the cam 320 to drive the baffle 410 to rotate in a second rotation direction (for example, counterclockwise), thereby restoring the baffle 410 to the first opening 211 of the outer door front cover 210.
[0078] In the embodiment of the present invention, when the baffle 410 is located at the first opening 211 of the outer door front cover 210 , the first spring 332 is just fully released from compression and restored to its original length.
[0079] In a specific embodiment, the elastic pin 340 may include a second locking pin 341 and a second spring 342. The second spring 342 is configured to elastically connect the cam 320 to the second locking pin 341. For example, the two ends of the second spring 342 may be connected to the cam 320 and the second locking pin 341, respectively. The second spring 342 is adapted to be compressed by the second locking pin 341 as the cam 320 rotates, causing the second locking pin 341 to abut against the sidewall 313 of the housing 310. When the second locking pin 341 rotates into the slot 315 in the sidewall 313, the second spring 342 at least partially releases the compression, allowing the second locking pin 341 to extend into the slot 315.
[0080] Reference Figure 7 The linkage mechanism 300 may further include a cam cover 360 and a housing cover 370 . The cam cover 360 covers the cam 320 . The housing cover 370 covers the space enclosed by the bottom wall 312 and the side wall 313 of the housing 310 .
[0081] Reference Figure 10 When the linkage device and the double-door device are in the initial state of opening the door, the baffle 410 covers the first opening 211 of the outer door front cover 210, the second lock pin 331 abuts against the side wall 313 of the shell 310, the resetter 600 extends from the outside of the shell 310 to the slot 315, the first lock pin 331 disengages from the connecting rod 500, and the inner door 100 disengages from the outer door 200.
[0082] Reference Figure 11 When the baffle 410 is pushed inward, the transmission member 420 connected to the baffle 410 rotates around the first pivot shaft 301 in a first rotation direction (for example, clockwise) and drives the cam 320 connected thereto to rotate around the second pivot shaft 302 in a second rotation direction (for example, counterclockwise). When the cam 320 rotates around the second pivot shaft 302 in the second rotation direction (for example, counterclockwise), it abuts against the first lock pin 331 and drives the first lock pin 331 to move toward the connecting rod 500. When the first lock pin 331 moves toward the connecting rod 500, it is inserted into the socket 510 of the connecting rod 500 to connect the connecting rod 500, thereby connecting the outer door 200 and the inner door 100.
[0083] At the same time, the second lock pin 341 is adapted to abut against the side wall 313 of the housing 310 when rotating along with the cam 320 in the second rotational direction (e.g., counterclockwise), and abut against the resetter 600 located outside the housing 310 when rotating to the locking slot 315 of the side wall 313. The second spring 342 is adapted to be compressed by the second lock pin 341 when rotating along with the cam 320 in the second rotational direction (e.g., counterclockwise), and remain compressed when the second lock pin 341 abuts against the resetter 600.
[0084] Reference Figure 12 and 13 The second locking pin 341 and the resetter 600 respectively have a first inclined surface 341a and a second inclined surface 600a adapted to abut against each other. The first inclined surface 341a is adapted to tilt inward, i.e., tilted toward the resetter 600, and the second inclined surface 600a is adapted to tilt outward, i.e., tilted toward the second locking pin 341.
[0085] When the second locking pin 341 abuts the resetter 600, the projections of the first inclined surface 341a and the second inclined surface 600a in a plane parallel to the extension and contraction direction of the second locking pin 341 (the second locking pin 341 can extend and contract relative to the locking slot 315 of the side wall 313) at least partially overlap. This ensures that the second locking pin 341 is subjected to a force f applied by the resetter 600 when abutting the resetter 600.
[0086] Reference Figure 12 When the second lock pin 341 abuts the resetter 600, the resetter 600 applies a force f to the second lock pin 341. This force f can be decomposed into a first force component f1 parallel to the extension and retraction direction of the second lock pin 341 and a second force component f2 perpendicular to the first force component f1. The first force component f1 is adapted to prevent the second lock pin 341 from extending into the retaining groove 315 of the side wall 313 and to maintain compression of the second spring 342 connected to the second lock pin 341. The second force component f2 is adapted to prevent the second lock pin 341 from continuing to rotate in the second rotational direction.
[0087] Reference Figure 14 When the outer door 200 is pulled outward, the housing 310 moves relative to the resetter 600 toward the outer door 200, causing the resetter 600 to be offset from the retaining slot 315 in the sidewall 313. When the resetter 600 is offset from the retaining slot 315, the force f exerted by the resetter 600 on the second lock pin 341 disappears. At this point, the second spring 342 can at least partially release its compression, allowing the second lock pin 341 to extend into the retaining slot 315, restricting the rotation of the cam 320 and thus ensuring the stability of the connection between the outer door 200 and the inner door 100.
[0088] Reference Figure 15When the outer door 200 and the inner door 100 are stably connected, the outer door 200 can be continuously pulled outward so that both the outer door 200 and the inner door 100 are opened at the same time.
[0089] In some preferred specific examples, the opening angles of the outer door 200 and the inner door 100 may be within a range of 0 degrees to 90 degrees, wherein 90 degrees is included and 0 degrees is not included.
[0090] Reference Figure 16 When the linkage device and the double-door device are in the initial state of closing the door, the baffle 410 is located on the inner side of the outer door front cover 210, the second lock pin 331 extends into the slot 315 of the side wall 313, the resetter 600 is staggered with the slot 315, the first lock pin 331 is connected to the connecting rod 500, and the inner door 100 is connected to the outer door 200.
[0091] Reference Figure 17 When the outer door 200 is pushed inward, the housing 310 moves inward along with the outer door 200, and the slot 315 of the side wall 313 of the housing 310 contacts the resetter 600. When the resetter 600 contacts the slot 315, the resetter 600 contacts the second lock pin 341 and compresses the second spring 342 connected to the second lock pin 341, causing the second lock pin 341 to exit the slot 315.
[0092] When the second lock pin 341 exits the slot 315, the first spring 332 can at least partially release its compression, causing the first latch 331 to move away from the connecting rod 500 and disengage from the connecting rod 500. This in turn causes the driving cam 320 to rotate in a first rotational direction (e.g., clockwise) to return the blocking plate 410 to the first opening 211. When the first lock pin 331 disengages from the connecting rod 500, the outer door 200 is disconnected from the inner door 100.
[0093] Reference Figure 18 When the linkage device and the double-door device are in the closed state, the baffle 410 covers the first opening 211 of the outer door front cover 210, the second lock pin 331 abuts against the side wall 313 of the shell 310, the resetter 600 extends from the outside of the shell 310 to the slot 315, the first lock pin 331 disengages from the connecting rod 500, and the inner door 100 disengages from the outer door 200.
[0094] Reference Figures 19 to 22 The embodiment of the present invention further provides a clothes processing device 1. The clothes processing device 1 includes a housing 20, an outer tub 30, an inner drum 40, an inner door 100, an outer door 200, and a linkage device 10 provided in the embodiment of the present invention.
[0095] In the embodiment of the present invention, the clothing processing device 1 may be a drum washing machine, a washer-dryer, a clothes dryer, or other equipment suitable for washing and drying clothing.
[0096] Specifically, the outer barrel 30 is fixedly arranged in the box body 20, and the inner barrel 40 is rotatably arranged in the outer barrel 30. The inner barrel 40, the outer barrel 30 and the box body 20 are respectively provided with storage openings suitable for taking and placing clothes (not shown in the figure). The inner door 100 is hinged to the outer barrel 30 to open or close the storage opening of the outer barrel 30, and the outer door 200 is hinged to the front panel 21 of the box body 20 to open or close the storage opening of the box body 20.
[0097] In a specific implementation, the inner door 100 and the outer door 200 are adapted to simultaneously open or close corresponding storage openings. The linkage device 10 is used to connect the inner door 100 and the outer door 200 when they are simultaneously opened, and to disconnect the inner door 100 and the outer door 200 when they are simultaneously closed.
[0098] In an embodiment of the present invention, the linkage mechanism 300 and the baffle assembly 400 of the linkage device 10 are installed on the outer door 200, the connecting rod 500 is installed on the inner door 100, and the resetter 600 is fixed on the back side 22 of the front panel 21 of the box body 20, that is, the side of the front panel 21 facing the inner door 100.
[0099] In some preferred specific examples, when the outer door 200 is disconnected from the inner door 100, a certain distance is maintained between the outer door 200 and the inner door 100 to avoid the movement of the inner drum 40 during operation of the clothing processing device 1 affecting the stability of the outer door 200 and the front panel 21 of the box body 20.
[0100] Reference Figure 21 and Figure 22 The laundry processing apparatus 1 further includes a sealing ring 50 fixed to the inner side of the inner door 100. The sealing ring 50 is adapted to be squeezed along a normal direction F to seal the outer tub 30 when the inner door 100 and the outer door 200 are closed. The normal direction F is a direction perpendicular to the plane in which the diameter of the sealing ring 50 lies.
[0101] In order to distinguish the technical solutions of the embodiments of the present invention from those of the prior art, in the following description, the sealing ring in the embodiments of the present invention is collectively referred to as the first sealing ring 50, the sealing ring in the prior art is collectively referred to as the second sealing ring 50', the door glass in the embodiments of the present invention is collectively referred to as the first door glass 60, and the door glass in the prior art is collectively referred to as the second door glass 60'.
[0102] In the prior art, the door of a laundry processing appliance is typically a single door mounted on the front panel of the appliance housing. This single door is fitted with a second door glass 60' that is recessed deeply toward the outer tub. A second sealing ring 50' is mounted on the outer tub. When the single door is closed, the second door glass 60' presses against the second sealing ring 50' in a radial direction F', sealing the outer tub.
[0103] In the prior art, due to the large distance between the front panel of the cabinet and the outer tub, the second door glass 60' needs to be deeply recessed toward the outer tub to close the outer tub's storage opening. Consequently, the second door glass 60' is typically very thick and has a complex shape, making it difficult to apply explosion-proof film to its surface. This poses a risk of shattering.
[0104] In addition, the second sealing ring 50 ′ usually has a groove 51 ′. When the second sealing ring 50 ′ is squeezed along the radial direction F′, the accumulated water in the groove 51 ′ cannot be discharged, thereby causing the second sealing ring 50 ′ to be prone to mold.
[0105] In this embodiment of the present invention, the first door glass 60 is mounted on the inner door 100, and the first sealing ring 50 is mounted on the inner side of the inner door 100 and engages with the outer periphery of the first door glass 60. When the inner door 100 is closed, the first sealing ring 50 is squeezed by the outer tub 30 along the normal direction F, thereby sealing the outer tub 30.
[0106] In an embodiment of the present invention, since the first door glass 60 is installed on the inner door 100 and the inner door 100 is hinged to the outer barrel 30, the first door glass 60 can have a smaller thickness and a simpler shape, and can be engaged with the outer barrel 30 when the inner door 100 is closed.
[0107] Since the first door glass 60 has a relatively small thickness and a simple shape, an explosion-proof film can be coated on its surface to reduce the risk of the first door glass 60 being broken.
[0108] In addition, when the inner door 100 is closed, the first sealing ring 50 will be squeezed by the outer tub 30 along the normal direction F and will not easily accumulate water or mold.
[0109] Although specific embodiments have been described above, these embodiments are not intended to limit the scope of the present disclosure, even when only a single embodiment is described with respect to specific features. The feature examples provided in the present disclosure are intended to be illustrative, not limiting, unless otherwise stated. In specific implementations, the technical features of one or more dependent claims may be combined with the technical features of the independent claims, depending on actual needs and where technically feasible, and the technical features from the corresponding independent claims may be combined in any appropriate manner rather than solely through the specific combinations listed in the claims.
[0110] Although the present invention is disclosed above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
