The door body 200 is provided with a lock tongue 210, and a lock 300 is provided on the box body 100, located on one side of the clothing inlet. There are four states between the lock tongue 210 and the lock 300, namely, a detachable positioning state, a locked state, an unlocked state, and a disengaged state. The lock tongue 210 can be detachably positioned on the lock 300 so that the door body 200 closes the clothing loading port. At this time, the user can pull the door body 200 to open the door body 200, and the lock tongue 210 and the lock 300 are in a detachable positioning state; the lock tongue 210 can also be locked to the lock 300 so that the door body 200 is locked to the clothing loading port, and the lock tongue 210 and the lock 300 are in a locked state; the lock tongue 210 can be in contact with the lock 300 but not connected, and it is an unlocked state; when the lock tongue 210 is opened with the door body 200, the lock tongue 210 can also be completely separated from the lock 300, and the lock tongue 210 and the lock 300 are in a disengaged state.

[0070] More specifically, Figure 8 A schematic diagram showing the structure of a door opener and closer provided by an embodiment of the present invention is shown; Fig. 9 A cross-sectional view of a door opening and closing device according to an embodiment of the present invention is shown. Figure 3 , Figure 4 , Figure 8 and Fig. 9 The door opener and closer 400 is arranged at the rotation connection between the door body 200 and the box body 100, and can drive the door body 200 to rotate from the first preset angle to close to the third preset angle, or rotate from the third preset angle to open to the second preset angle. When the door body 200 rotates from the first preset angle to the third preset angle, the lock 300 can connect the lock tongue 210 and drive the door body 200 to rotate through the lock tongue 210 to close the clothing delivery port. When the lock tongue 210 and the lock 300 are converted from the separable positioning state to the unlocked state, the door opener and closer 400 can drive the door body 200 to rotate and open to the second preset angle, and the second preset angle is greater than the third preset angle. The first preset angle, the second preset angle and the third preset angle are all the angles between the door body 200 and the clothing delivery port.

[0071] More specifically, the door opener and closer 400 includes a cam 410 and an energy storage assembly 420. The cam 410 and the energy storage assembly 420 are connected between the door body 200 and the box body 100. During the opening process of the door body 200, after the lock tongue 210 and the lock 300 are converted from the locked state to the separable positioning state, the energy storage assembly 420 and the cam 410 rotate relative to each other so that the door body 200 is opened to a second preset angle. During the closing process of the door body 200, after the door body 200 is closed to the first preset angle, the energy storage assembly 420 and the cam 410 rotate relative to each other so that the door body 200 continues to close to a third preset angle.

[0072] As an option, in the present embodiment, the energy storage assembly 420 is movably disposed on the door body 200 , and the cam 410 is coaxially fixedly connected to the hinge shaft 220 of the door body 200 .

[0073] In another embodiment, the cam 410 can rotate together with the door body 200, and the energy storage assembly 420 is disposed on the box body 100, and the energy storage assembly 420 and the cam 410 can rotate relative to each other. Fig.11 shown.

[0074] During the closing process of the door body 200, when the door body 200 is closed to the first preset angle, the lock tongue 210 and the lock 300 are still in a disengaged state. After the door body 200 is closed to the first preset angle, the energy storage assembly 420 can automatically operate, and the energy storage assembly 420 and the cam 410 rotate relative to each other, so that the door body 200 continues to close to the third preset angle to close the clothing loading port. When the door body 200 is at the third preset angle, the lock tongue 210 is in contact with the lock 300 but not connected, and the two are in a separable positioning state. When the lock tongue 210 and the lock 300 are in a separable positioning state, if the clothing processing device sends a locking start signal, the lock 300 can operate to lock the lock tongue 210, so that the two are converted into a locked state.

[0075] In this embodiment, the first preset angle may be 30°-50°, and the third preset angle may be 2°-5°. The first preset angle is preferably 45°, and the third preset angle is preferably 3°. Through the above settings, the degree of automation of the door closing process of the clothing processing device can be improved to enhance the user experience.

[0076] During the opening process of the door body 200, after the lock tongue 210 and the lock 300 are converted from the locked state to the unlocked state, the energy storage component 420 can automatically operate, and the energy storage component 420 and the cam 410 rotate relative to each other so that the door body 200 is opened to the second preset angle. At this time, the water vapor in the box 100 can be released to prevent bacteria and odor from growing. In this embodiment, the second preset angle can be specifically 30°-50°, and the second preset angle and the first preset angle can be equal or unequal. The second preset angle is preferably 45°.

[0077] Continue to refer to Figure 5-Figure 7 The lock 300 includes a fixed housing 310, a pre-tightening member 320 and a pre-tightening elastic element 330. The fixed housing 310 is mounted on the box 100, the pre-tightening member 320 is swingably disposed in the fixed housing 310, and the pre-tightening elastic element 330 is connected between the pre-tightening member 320 and the fixed housing 310, so that the pre-tightening member 320 is in a pre-tightening position. The lock tongue 210 is provided with a card slot 211, and the lock tongue 210 can extend into the fixed housing 310. When the lock tongue 210 and the lock 300 are in a separable positioning state, the pre-tightening member 320 swings to the pre-tightening position and is card-fitted in the card slot 211. At this time, the lock tongue 210 is connected to the lock 300 but is not locked. Before the washing process of the clothing processing device starts, the user can pull the door body 200 to disengage the lock tongue 210 from the pre-tightening member 320, and pull the lock tongue 210 out of the fixed shell 310 to open the door body 200.

[0078] Specifically, refer to Figure 6 The pre-tightening member 320 is provided with a pre-tightening protrusion 321, and the pre-tightening protrusion 321 can be clamped in the clamping groove 211. The groove wall of the clamping groove 211 is sloped, and the pre-tightening protrusion 321 is provided with a sloped guide surface. In the process of the lock tongue 210 and the lock 300 being converted from the unlocked state to the separable positioning state, the sloped guide surface can slide relative to the groove wall of the clamping groove 211, so that the pre-tightening protrusion 321 enters the clamping groove 211. In the process of the lock tongue 210 and the lock 300 being converted from the separable positioning state to the separated state, the sloped guide surface can slide relative to the groove wall of the clamping groove 211, so that the pre-tightening protrusion 321 moves out of the clamping groove 211.

[0079] To be more specific, the above-mentioned sloped guide surface is divided into an entry slope and an exit slope. The slope angle of the entry slope is smaller, which is beneficial to reducing the resistance when the pre-tightening protrusion 321 enters the clamping groove 211; the slope angle of the exit slope is larger, which is beneficial to achieving the set positioning force value of the detachable positioning state.

[0080] Specifically, the lock 300 further includes a swing housing 340 and a locking member. The swing housing 340 is swingably disposed in the fixed housing 310, and the swing housing 340 can swing and switch between a locked position and an unlocked position, and a swing shaft 341 of the swing housing 340 is located at a vertex of the swing housing 340. The locking member is disposed in the swing housing 340 and is spaced apart from the preload member 320, and the lock tongue 210 can extend into the space between the preload member 320 and the locking member. When the swing housing 340 swings to the locked position, the locking member can be connected to the lock tongue 210, and the subsequent locking member can further lock with the lock tongue 210 under its own action. When the swing housing 340 swings to the unlocked position, the locking member can be separated from the lock tongue 210, and at this time, the lock tongue 210 and the lock 300 are in a separable positioning state.

[0081] More specifically, in this embodiment, the locking member is a locking screw 350, and an involute spiral structure is provided on the circumference of the locking screw 350. The locking screw 350 is rotatably provided around its own axis in the swing housing 340. A toothed locking portion 212 is provided on the side of the locking tongue 210 away from the clamping groove 211. The locking screw 350 can be rotated so that the toothed locking portion 212 is meshed and locked with the locking screw 350. The locking screw 350 can also be rotated in the opposite direction to drive the locking tongue 210 to withdraw from between the preload member 320 and the locking screw 350.

[0082] More specifically, the lock 300 further includes a first drive device 360 ​​and a second drive device 370. The first drive device 360 ​​is disposed on the swing housing 340 and is transmission-connected to the fixed housing 310, and can drive the swing housing 340 to swing relative to the fixed housing 310 to switch between the locked position and the unlocked position. The second drive device 370 is disposed on the swing housing 340 and is transmission-connected to the locking screw 350, and can drive the locking screw 350 to move, so as to lock with the lock tongue 210 or drive the lock tongue 210 to withdraw from between the preload 320 and the locking screw 350 to form an unlocked state, and can also drive the lock tongue 210 to extend into the space between the preload 320 and the locking screw 350. In this embodiment, the first drive device 360 ​​and the second drive device 370 can both be drive motors in the prior art.

[0083] More specifically, the lock 300 also includes a lock tongue proximity sensor, a lock tongue in-position sensor, and a swing position sensor. The lock tongue proximity sensor can send a lock tongue proximity signal when the lock tongue 210 approaches the lock 300, and at this time, the first drive device 360 ​​starts to drive the swing housing 340 to swing from the unlocked position to the locked position. It should be noted that when the user is in a hurry, the door body 200 can be directly closed at the clothing inlet by pushing the door body 200, that is, the lock tongue 210 is quickly inserted into the space between the pre-tightening member 320 and the locking screw 350. At this time, since the swing housing 340 is still in the unlocked position, it will not cause collisions and other problems.

[0084] When the lock tongue 210 moves to be connected to the preload member 320, the lock tongue in place sensor sends a lock tongue in place signal. At this time, the first drive device 360 ​​drives the swing housing 340 to swing from the locked position to the unlocked position, so that the lock tongue 210 is positioned only by the preload member 320. At this time, the lock tongue 210 and the lock 300 are in a detachable positioning state. At this time, the user can pull the door body 200 to open the clothing inlet and perform operations such as adding clothes.

[0085] The swing position sensor can detect the swing position of the swing housing 340 and determine whether the swing housing 340 is in the unlocked position or the locked position. When the swing housing 340 detects that the swing housing 340 is in the unlocked position and the laundry processing device sends a locking start signal, the first driving device 360 ​​can drive the swing housing 340 to swing from the unlocked position to the locked position, and the second driving device 370 can drive the locking screw 350 to lock with the lock tongue 210. After the above process is completed, the door body 200 is locked at the laundry inlet, thereby ensuring the safety of the subsequent laundry process.

[0086] More specifically, refer to Figure 5 and Figure 7 The lock 300 further includes a transmission rack 381 and a transmission gear set 390. The first driving device 360 ​​and the transmission gear set 390 are in transmission connection and are both connected to the swing housing 340. The fixed housing 310 is provided with a slide groove 311. The transmission rack 381 is provided in the slide groove 311 and meshes with the transmission gear set 390. The first driving device 360 ​​can drive the transmission gear set 390 to rotate, so as to drive the swing housing 340 to swing relative to the fixed housing 310 along the extension direction of the slide groove 311, so as to switch between the unlocking position and the locking position.

[0087] Preferably, the lock 300 further includes a swing elastic element 382. The transmission rack 381 is movably disposed in the slide groove 311, and the swing elastic element 382 is connected between one end of the transmission rack 381 and the abutting boss 313 in the fixed housing 310. In the process of the swing housing 340 swinging from the unlocking position to the locking position, the transmission rack 381 can move in the slide groove 311, and the swing elastic element 382 can be compressed to store energy. When the toothed locking portion 212 is opposite to the spiral teeth of the locking screw 350 and cannot mesh, the swing housing 340 is temporarily unable to swing to the locking position. At this time, the first driving device 360 ​​drives the transmission gear set 390 to rotate, thereby driving the transmission rack 381 to move in the direction where the swing elastic element 382 is located, and the swing elastic element 382 is compressed to store energy. At the same time, the second drive device 370 drives the locking screw 350 to rotate, and the spiral teeth of the rotating locking screw 350 move relative to the tooth portion of the toothed locking portion 212. When the two move to the point where the tooth tops are staggered with each other and the tooth tops are opposite to the tooth grooves, under the elastic action of the swinging elastic element 382, ​​the two can quickly engage with each other to allow the swinging housing 340 to swing to the locking position.

[0088] Preferably, a through opening 312 is provided on the side of the fixed housing 310, and a pull cord (not shown) is connected to the swing housing 340, which can be extended from the through opening 312. The pull cord can drive the swing housing 340 to swing relative to the fixed housing 310, so that the swing housing 340 swings from the locked position to the unlocked position. In other words, in an emergency, the user can pull the swing housing 340 to swing by the pull cord, and the transmission rack 381 and the transmission gear set 390 swing together with the swing housing 340 in the direction of being pulled. During this process, the swing elastic element 382 is compressed, which can disengage the lock tongue 210 from the locking screw 350 and unlock the door, thereby realizing manual door opening, avoiding damage to the entire clothing processing device and the door opener and closer 400, and ensuring the safety and reliability of the product. It should be noted that the pull cord can be a soft plastic rope or a flexible strip of other materials.

[0089] Fig.10 FIG. 2 is a schematic diagram showing the structure of a cam provided by an embodiment of the present invention. Figure 8-Figure 10 The cam 410 is provided with an automatic door opening track 411, a manual door opening energy storage track 412, a manual door opening and closing track 413 and an automatic door closing track 414, and the energy storage component 420 can move relatively along the automatic door opening track 411, the manual door opening energy storage track 412, the manual door opening and closing track 413 or the automatic door closing track 414.

[0090] Specifically, during the opening process of the door body 200, the energy storage assembly 420 moves relatively along the automatic door opening track 411 and the manual door opening energy storage track 412. During the closing process of the door body 200, the energy storage assembly 420 moves relatively along the manual door opening track 413 and the automatic door closing track 414.

[0091] Specifically, the door opening and closing device 400 further includes a bracket 430, and the energy storage assembly 420 includes a first sleeve 421, a second sleeve 422, a ball 423, an opening and closing door elastic element 424, and a rotating shaft 425. The ball 423, the second sleeve 422, and the opening and closing door elastic element 424 are coaxially arranged and are all arranged in the first sleeve 421. The ball 423 is movably arranged at the front end of the second sleeve 422, and the opening and closing door elastic element 424 is sandwiched between the rear end of the second sleeve 422 and the inside of the rear end of the first sleeve 421. The rotating shaft 425 is inserted into the hole at the rear end of the first sleeve 421 and the hole at the rear end of the bracket 430. The first sleeve 421 can swing relative to the bracket 430 around the rotating shaft 425. The bracket 430 is installed on the door body 200, and the front end of the bracket 430 is rotatably sleeved on the hinge shaft 220.

[0092] Reference Fig.11 In another embodiment, the bracket 430 is fixedly disposed on the inner wall of the box body 100, the energy storage assembly 420 is disposed in the bracket 430, and the cam 410 is relatively fixedly disposed on the door body 200 and can rotate together with the door body 200, thereby realizing the relative movement of the energy storage assembly 420 and the cam 410.

[0093] When the door of the laundry processing device needs to be opened, the second driving device 370 drives the locking screw 350 to rotate, so that the locking screw 350 and the toothed locking portion 212 are disengaged from the unlocking, and the elastic force of the door opening and closing elastic element 424 causes the ball 423 to roll and move on the automatic door opening track 411 on the cam 410, thereby generating a force to open the door outward, so that the door is opened to a second preset angle, and the automatic door opening action of the laundry processing device is completed. When the door is subsequently opened manually to a larger opening angle, the ball 423 rolls and moves on the manual door opening energy storage track 412 on the cam 410, so that the door opening and closing elastic element 424 is compressed to store energy.

[0094] When the washing machine door is closed, the door body 200 rotates to drive the hinge shaft 220 to rotate, so that the ball 423 rolls and moves along the manual door opening and closing track 413 on the cam 410, and when it moves to the automatic door closing track 414, the door body 200 is closed to the first preset angle, and the door opener and closer 400 generates a force to close the door inward. When the door body 200 continues to automatically rotate a certain distance to the third preset angle, the lock tongue 210 contacts the locking screw 350, and then under the action of the locking screw 350, it is clamped with the pre-tightening member 320 to form pre-tightening, so that the door body 200 is closed at the clothing loading port.

[0095] By setting an automatic door opening track 411 and an automatic door closing track 414 on the cam 410, and cooperating with the elastic force of the door opening and closing elastic element 424 and the rolling of the ball 423, when washing clothes, it is only necessary to manually close the door to the first preset angle, and then the door can be automatically closed, thereby improving the degree of automation of the door closing process and enhancing the user experience. When the clothes are washed, the lock 300 is automatically unlocked until the locking screw rod 350 and the lock tongue 210 are unlocked, and the door opener 400 can generate a force to open the door outward, so that the door body 200 is automatically opened to the second preset angle, releasing the water vapor in the box 100, avoiding the growth of bacteria and odor, and improving the user experience.
