Description

Technical Field

[0001] The present invention belongs to the technical field of clothing processing, and in particular relates to a clothing processing device. Background Art

[0002] Washing machines and other clothing processing equipment are common household appliances used to wash clothes. The washing tub module of the washing machine is arranged in the body, and a pulsator is provided at the bottom of the washing tub module. During washing, the rotation of the pulsator agitates the clothes and water in the washing tub module, thereby achieving the cleaning of the clothes, which provides a lot of convenience for people's daily life. However, cross-infection between different clothes still makes many users have concerns about the safety of washing machines. In addition, in the dehydration scheme of existing washing machines, it is usually adopted to let the inner barrel and the pulsator rotate synchronously and at high speed, so that the water on the washing is separated from the washing under the action of centrifugal force and discharged from the gap between the inner barrel and the outer barrel. This dehydration method is prone to produce large vibration and noise, and is easy to cause large damage to the washing.

[0003] In order to avoid cross infection between different clothes and reduce the vibration and noise generated when the washing machine is dehydrating, the manufacturer has launched a washing machine with a replaceable barrel and negative pressure dehydration. Specifically, the barrel structure is detachably installed in the shell of the washing machine, the barrel wall of the barrel structure is deformable and has a certain deformation margin, and the washing machine is provided with a negative pressure component connected to the barrel structure, which sucks water and air in the barrel structure, causing the barrel wall to contract and squeeze the clothes to achieve dehydration.

[0004] However, in the existing washing machines with replaceable barrels and capable of negative pressure dehydration, the upper end of the barrel wall of the barrel structure is clamped between the door and the shell, the barrel bottom is generally magnetically connected to the accommodating cavity in the shell, and the impeller shaft and the drive shaft are connected by a spline quick-plug. Under this installation method, the washing machine has poor locking force on the barrel bottom of the barrel structure. During use, if the negative pressure increases, the barrel wall is easily shortened in height during the contraction process due to the barrel structure being sucked up and down, causing the connection structure between the barrel bottom and the shell to separate, making the washing machine unable to work normally, affecting the user experience.

[0005] Therefore, designing a clothing processing device that can avoid the separation of the connection structure between the bottom of the barrel structure and the shell has become a technical problem that needs to be solved urgently by technical personnel in this field.

[0006] In view of this, the present invention is proposed. Summary of the invention

By arranging a limiting device linked with a door body, when the door body is closed, not only the upper end of a barrel wall of a barrel structure can be pressed by the door body, but also the barrel bottom of the barrel structure can be pressed by the limiting device, thereby solving the problem that in the existing clothing processing device with a replaceable barrel and capable of negative pressure dehydration, the connection structure between the barrel bottom and the shell body is easily separated during negative pressure dehydration.

[0054] Embodiment 1

[0055] like Figures 1 to 5As shown, in an embodiment of the present invention, a clothes processing device is introduced, which includes a shell 1, a door body 4 installed on the top of the shell 1, and a barrel structure 3 arranged inside the shell 1.

[0056] Specifically, the clothes processing device is a clothes processing device with a replaceable barrel structure 3, and the barrel structure 3 is detachably installed in the housing 1 of the clothes processing device.

[0057] The barrel structure 3 is replaceably installed in the housing 1 of the clothing processing device, so that one clothing processing device can be equipped with multiple barrel structures 3, which is convenient for replacing the barrel structure 3. During use, one person can use one barrel or multiple barrels, and the number of barrel structures 3 can be configured according to the use requirements to achieve classified washing, which can prevent cross infection when the clothing processing device washes different clothes. At the same time, there is no need to configure multiple clothing processing devices, which saves costs.

[0058] In this embodiment, the barrel structure 3 includes a barrel wall and a barrel bottom arranged at the bottom of the barrel wall. Specifically, the barrel wall extends in a vertical direction, and openings are arranged at the upper and lower ends respectively. The barrel bottom is arranged at the lower end of the barrel wall, and the barrel bottom blocks the lower end of the barrel wall, and the upper end of the barrel wall constitutes the barrel opening.

[0059] The barrel wall is made of soft material and is provided with a pleated portion 31, which is used to provide a margin for the deformation of the barrel structure 3. During use, the negative pressure component of the clothing treatment device sucks water and air in the barrel structure 3 to shrink the barrel structure 3, and the inner wall of the barrel structure 3 squeezes the clothes in the barrel structure 3 to achieve dehydration.

[0060] When the existing clothing processing equipment is performing negative pressure dehydration, the upper end of the barrel wall of the barrel structure 3 is clamped between the door body 4 and the shell 1, and the upper end of the barrel structure 3 is sealed by the door body 4. The barrel bottom of the barrel structure 3 is generally magnetically connected to the bottom wall of the accommodating cavity in the shell 1, and the impeller shaft and the drive shaft 13 are connected by a spline quick-plug connection. Under this installation method, the clothing processing equipment has a poor locking force on the bottom of the barrel structure 3. During use, if the negative pressure increases, the barrel structure 3 is easily sucked up and down during the contraction process, resulting in its height being shortened, causing the connection structure between the barrel structure 3 and the shell 1 to separate, making the clothing processing equipment unable to work normally, affecting the user experience.

[0061] like Figures 3 to 5 As shown, the clothing processing device provided in the embodiment of the present invention further includes a limiting device 7, which is arranged in the shell 1, including a first position for limiting the bottom of the barrel structure 3 as the door body 4 is closed, and a second position for releasing the limit on the bottom of the barrel structure 3 as the door body 4 is opened.

[0062] By setting a limiting device 7 and setting the limiting device 7 to be linked with the door body 4 of the clothing processing equipment, it switches between the first position and the second position as the door body 4 is closed and opened, so that when the door body 4 is closed, not only the upper end of the barrel wall of the barrel structure 3 can be pressed by the door body 4, but also the barrel bottom of the barrel structure 3 can be pressed by the limiting device 7. During use, the axial length of the barrel wall can be kept unchanged. During the negative pressure dehydration process, the barrel bottom is pressed in the shell 1 to prevent the connection structure between the barrel bottom and the shell 1 from being separated, thereby ensuring the dehydration performance and improving the working stability of the clothing processing equipment. At the same time, it can ensure that the barrel structure 3 is easy to disassemble and assemble.

[0063] In this embodiment, the limiting device 7 includes a clamping part 71 for clamping the bottom of the barrel, and a transmission part 72 for driving the clamping part 71 to move. Specifically, the clamping part 71 is arranged on the inner wall of the shell 1, including a first position for limiting the installation position of the bottom of the barrel, and a second position for releasing the limit of the bottom of the barrel; the transmission part 72 has an upper end that is transmission-connected with the door body 4, and a lower end that is used to drive the clamping part 71 to move to the first position. The transmission part 72 drives the clamping part 71 to move to the second position or the first position as the door body 4 is opened and closed.

[0064] Preferably, in this embodiment, the position limiting device 7 further includes an elastic member 73 for driving the clamping portion 71 to move to the second position. In the process of closing the door body 4, the door body 4 drives the clamping portion 71 to move to the first position through the transmission portion 72 to overcome the elastic force of the elastic member 73. After the door body 4 is closed, the clamping portion 71 moves to the first position. At this time, the locking force of the closing of the door body 4 keeps the clamping portion 71 in the first position, and the barrel bottom of the barrel structure 3 is continuously locked; when the door body 4 is opened, the door body 4 releases the locking of the clamping portion 71, and the clamping portion 71 moves to the second position under the action of the elastic member 73, releasing the locking of the barrel bottom of the barrel structure 3, and the transmission portion 72 is reset accordingly.

[0065] Preferably, the clamping part 71 is connected to the inner wall of the shell 1 through an elastic member 73, and slides along the radial direction of the shell 1; the transmission part 72 is arranged between the shell 1 and the barrel wall of the barrel structure 3, slides along the axial direction of the shell 1, and the lower end abuts against the clamping part 71. Specifically, the transmission part 72 abuts against the end of the clamping part 71 away from the barrel structure 3, preferably, the transmission part 72 abuts against the clamping part 71 through an inclined surface inclined upward in a direction close to the axis of the shell 1, and / or the clamping part 71 abuts against the transmission part 72 through an inclined surface inclined upward in a direction close to the axis of the shell 1.

[0066] Thus, when the door body 4 is closed, the driving transmission part 72 squeezes the clamping part 71. Specifically, the lower end of the transmission part 72 squeezes the clamping part 71 away from one end of the barrel structure 3 through the inclined surface that is inclined upward in the direction close to the axis of the shell 1, and / or the lower end of the transmission part 72 squeezes the inclined surface on the clamping part 71 that is inclined upward in the direction close to the axis of the shell 1, thereby driving the clamping part 71 to slide in the direction close to the barrel structure 3, thereby limiting the barrel bottom of the barrel structure 3.

[0067] In this embodiment, the limiting device 7 corresponds to the barrel bottom of the barrel structure 3; a clamping plate 37 extending radially along the barrel structure 3 and cooperating with the limiting device 7 is provided on the barrel bottom. When the limiting device 7 moves to the first position, it is clamped with the clamping plate 37.

[0068] Specifically, the clamping portion 71 is configured as a slider extending radially of the housing 1 ; a first guide groove extending radially of the housing 1 for guiding the clamping portion 71 is provided in the housing 1 , and the slider is disposed in the first guide groove.

[0069] The housing 1 is provided with a receiving cavity for receiving the barrel structure 3 .

[0070] In some possible embodiments, the barrel structure 3 is installed in the accommodating cavity. When it is installed in place, the barrel bottom of the barrel structure 3 is spaced apart from the bottom wall of the accommodating cavity. When the door body 4 is closed, the clamping portion 71 extends out to limit the barrel bottom of the barrel structure 3, thereby preventing the barrel bottom of the barrel structure 3 from moving upward during the negative pressure dehydration process.

[0071] Preferably, in some other possible embodiments, when the barrel structure 3 is installed in place, the barrel bottom of the barrel structure 3 fits with the bottom wall of the accommodating cavity, and the slider is arranged on the bottom wall of the accommodating cavity and slides along the radial direction of the accommodating cavity. When the door body 4 is closed, the slider slides toward the barrel structure 3 to clamp the barrel bottom of the barrel structure 3 between the slider and the bottom wall of the accommodating cavity.

[0072] Preferably, in this embodiment, the first guide groove is arranged on the bottom wall of the accommodating cavity, and the first guide groove includes a left side wall and a right side wall extending along the sliding direction of the slider, and the left side wall and the right side wall of the first guide groove extend from the inner circumferential wall of the shell 1 toward the direction close to the axis of the shell 1.

[0073] Further preferably, in order to limit the movement of the slider to only sliding along the radial direction of the shell 1, a guide structure can be provided between the left and right side walls of the first guide groove and the left and right sides of the slider; the first guide groove can also be provided to include a top wall, and the top wall is provided at one end of the first guide groove close to the barrel structure 3 and is spaced apart from the inner circumferential wall of the shell 1, so that the lower end of the transmission rod 721 is inserted into the first guide groove from between the bottom wall of the first guide groove and the inner circumferential wall of the shell 1, and abuts against the slider. By providing the first guide groove to include a top wall, on the basis of the end of the slider away from the barrel structure 3 being abutted and limited by the transmission rod 721, the end of the slider close to the barrel structure 3 can be limited by the top wall of the first guide groove, thereby further enhancing the pressing effect on the barrel bottom of the barrel structure 3.

[0074] In this embodiment, the first guide groove and the barrel structure 3 are spaced apart.

[0075] In this embodiment, the bottom of the clamping plate 37 is in contact with the bottom wall of the accommodating cavity.

[0076] In this embodiment, the bottom of the clamping plate 37 is in contact with the bottom wall of the accommodating cavity, and the slider is provided with an avoidance gap for avoiding the thickness of the clamping plate 37. When the slider moves to the first position, the end of the clamping plate 37 is clamped in the avoidance gap.

[0077] Preferably, in the present embodiment, the distance between part of the slider at the avoidance notch and the bottom wall of the accommodating chamber gradually decreases in the direction away from the barrel structure 3, the distance between one end of the avoidance notch close to the barrel structure 3 and the bottom wall of the accommodating chamber is slightly larger than the thickness of the clamping plate 37, and the distance between one end of the avoidance notch away from the barrel structure 3 and the bottom wall of the accommodating chamber is slightly smaller than the thickness of the clamping plate 37, thereby ensuring both the smoothness of the movement of the slider to the first position and the pressing effect of the slider on the bottom of the barrel structure 3.

[0078] Preferably, in this embodiment, an engaging groove adapted to the shape of the snap plate 37 is further provided on the bottom wall of the accommodating cavity. When the barrel structure 3 is installed in place, the snap plate 37 is engaged in the engaging groove, and at this time, the slider can smoothly move to the first position. If the installation position of the barrel structure 3 is offset, the snap plate 37 cannot be embedded in the engaging groove. During the movement of the slider to the first position, the end of the slider abuts against the end of the snap plate 37, and it cannot be successfully moved to the first position, and the door body 4 cannot be closed smoothly. The user can judge whether the barrel structure 3 is installed in place based on this, so as to adjust the installation position of the barrel structure 3 in time to improve the user experience.

[0079] Preferably, in this embodiment, the barrel bottom of the barrel structure 3 is at least partially made of hard material, and the clamping plate 37 is arranged on the barrel bottom, on the portion made of hard material.

[0080] Specifically, in this embodiment, a folded edge 36 extending in the radial direction of the barrel wall toward the axis of the barrel wall is provided at the lower end of the barrel wall. The barrel structure 3 further includes a barrel bottom connector 32, which is made of a hard material and includes a first connector 321 and a second connector 322 clamped on both sides of the folded edge 36, the first connector 321 and the second connector 322 are connected by screws, and the first connector 321 and the second connector 322 are respectively sealed to the inner side and the outer side of the folded edge 36 on the sides close to each other, and specifically, the inner side and the outer side of the folded edge 36 are respectively provided with sealing edges for elastically abutting against the first connector 321 and the second connector 322.

[0081] Preferably, the outer periphery of the first connecting member 321 abuts against the inner wall of the barrel structure 3 , so that the folded edge 36 and the barrel bottom connecting member 32 constitute the barrel bottom of the barrel structure 3 , and the lower end of the barrel wall is supported by the barrel bottom connecting member 32 .

[0082] Preferably, in this embodiment, the clamping plate 37 is connected to the second connecting member 322 .

[0083] In this embodiment, the transmission part 72 includes a transmission rod 721 extending axially along the shell 1, and a transmission block 722 arranged at the lower end of the transmission rod 721 and abutting against the end of the slider away from the barrel structure 3. The transmission part 72 drives the clamping part 71 through the transmission block 722.

[0084] Preferably, an inclined surface inclined upward in a direction close to the axis of the shell 1 is arranged at the bottom of the transmission block 722 and / or at an end of the sliding block away from the barrel structure 3.

[0085] Preferably, in this embodiment, the bottom of the transmission block 722 and the end of the slider away from the barrel structure 3 are both provided with an inclined surface inclined upward in the direction close to the axis of the shell 1, and the inclined surface at the bottom of the transmission block 722 fits with the inclined surface at the end of the slider, thereby improving the transmission effect between the transmission part 72 and the clamping part 71 and the clamping effect of the transmission part 72 on the clamping part 71.

[0086] Preferably, in this embodiment, a second guide groove 74 is further provided between the inner wall of the shell 1 and the outer peripheral wall of the barrel structure 3, and the second guide groove 74 extends along the axial direction of the shell 1 and is used to guide the transmission part 72. The transmission rod 721 of the transmission part 72 is embedded in the second guide groove 74 and slides along the second guide groove 74.

[0087] An extension portion 11 extending radially toward the axis of the shell 1 is provided at the top of the shell 1 , and the inner circumference of the extension portion 11 is adapted to the shape of the upper end of the barrel structure 3 .

[0088] In this embodiment, the second guide groove 74 is arranged between the inner wall of the shell 1 and the outer peripheral wall of the barrel structure 3. Specifically, the second guide groove 74 is arranged on the extension portion 11 and extends downward from the bottom of the extension portion 11 along the axial direction of the shell 1.

[0089] Preferably, in this embodiment, the inner wall of the second guide groove 74 is in contact with the outer circumference of the transmission rod 721, and the second guide groove 74 is circumferentially limited with the transmission rod 721. The lower end of the second guide groove 74 is spaced apart from the slider.

[0090] In this embodiment, a driving opening 112 is provided on the extension portion 11 at a position corresponding to the upper end of the limiting device 7, and the driving opening 112 corresponds to the upper end of the second guide groove 74. A driving portion 75 corresponding to the driving opening 112 is provided on the door body 4; when the door body 4 is closed, the driving portion 75 is inserted into the driving opening 112 and abuts against the upper end of the limiting device 7, thereby driving the limiting device 7 to move to the first position.

[0091] like Figures 1 to 3 As shown, in this embodiment, one end of the door body 4 is hinged to the top of the housing 1, and a door lock 6 is arranged between the other end and the housing 1. In this embodiment, the door lock 6 includes a lock hook 61 extending downward from the periphery of the door body 4, and a lock port 62 arranged on the periphery of the top of the housing 1 and adapted to the lock hook 61. When the door body 4 is buckled, the lock hook 61 is inserted into the lock port 62 for locking.

[0092] The driving portion 75 protrudes from the bottom of the door body 4, and the shape of the driving portion 75 is adapted to the shape of the driving opening 112. Preferably, the side of the driving portion 75 away from the rotation center of the door body 4 extends obliquely in the direction away from the rotation center of the door body 4 along the closing direction of the door body 4, so that when the door body 4 rotates, the driving portion 75 and the extension portion 11 are prevented from interfering with each other, thereby improving the smoothness of opening and closing of the door body 4.

[0093] In this embodiment, the limiting devices 7 are provided in plurality and are arranged at intervals along the circumferential direction of the shell 1 . The door body 4 is provided with a plurality of driving parts 75 , and the driving parts 75 correspond to the limiting devices 7 one by one.

[0094] Preferably, in the present embodiment, the limiting device 7 is arranged in the housing 1 on a side close to the door lock 6 , so as to further avoid mutual interference between the driving portion 75 and the extending portion 11 .

The drainage pipeline of the washing machine is connected to the temporary storage chamber from the bottom of the temporary storage chamber, and a one-way valve is arranged on the drainage pipeline of the washing machine.

[0126] Thus, when the air pump is running, the air in the temporary storage chamber can be pumped out, so that negative pressure is formed in the temporary storage chamber, thereby pumping out the water and air in the barrel structure 3. After the water and air in the barrel structure 3 enter the temporary storage chamber, the water and air are separated, the water is temporarily stored at the bottom of the temporary storage chamber, and the air rises to the top of the temporary storage chamber and is pumped out by the air pump. When the air pump stops running, the water in the temporary storage chamber is discharged from the drainage pipeline.
