Description

Technical Field

[0001] The present invention belongs to the technical field of clothing processing, and in particular relates to a barrel structure, and also relates to a clothing processing device equipped with the barrel structure. 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 barrel structure that can avoid separation of the connection structure between the barrel bottom and the shell has become a technical problem that needs to be solved urgently by those skilled in the art.

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

[0007] The present invention provides a barrel structure. By arranging the barrel structure including a first positioning portion and a second positioning portion, the axial length of the barrel wall can be kept unchanged during use. During the negative pressure dehydration process, the contraction mode of the barrel wall is limited to radial contraction, which solves the problem that the connection structure between the barrel bottom and the shell body is easily separated during the negative pressure dehydration in the existing clothing processing equipment with replaceable barrels and capable of negative pressure dehydration.

[0048] Embodiment 1

[0049] like Figures 1 to 3 As shown, in an embodiment of the present invention, a barrel structure 3 is introduced, and the barrel structure 3 is applied to a clothing processing device with a replaceable barrel and capable of performing negative pressure dehydration.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] When the existing clothing processing equipment is performing negative pressure dehydration, the upper end 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 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.

The axial length of the barrel wall can be kept unchanged during use. During the negative pressure dehydration process, the barrel bottom is pressed tightly into the shell 1, and the contraction mode of the barrel wall is limited to radial contraction, which prevents 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.

A driving shaft 13 is provided at the bottom of the housing 1, and the driving shaft 13 and the pulsator shaft of the pulsator 34 are splined and plugged together, so that when the tub structure 3 is installed, the driving shaft 13 and the pulsator shaft are connected to each other for transmission connection, and when the tub structure 3 is disassembled, the connection structure between the driving shaft 13 and the pulsator shaft is quickly separated.

[0087] In this embodiment, a driving motor connected to the driving shaft 13 is further provided at the bottom of the shell 1, and the driving motor is used to drive the driving shaft 13 to rotate, thereby driving the impeller 34 to rotate.

The valve core has a first position for closing the valve body water channel and a second position for opening the valve body water channel.

[0089] In this embodiment, the drain valve 35 is arranged at one end of the drain port 33 away from the inner side of the barrel structure 3. The upper end of the valve body water channel of the drain valve 35 is connected with the interior of the barrel structure 3 through the drain port 33. A return spring is provided between the valve core and the drain port 33 to push the valve core to move downward to block the lower end of the valve body water channel.

[0090] A drainage opening assembly for driving the drainage valve 35 to open is disposed at the bottom of the housing 1 .

[0092] Specifically, the bottom of the valve core of the drain valve 35 is provided with support blocks protruding downward and arranged circumferentially. Preferably, the support blocks are provided with at least three blocks arranged circumferentially. The push rod 12 is coaxial with the valve core, and the push rod 12 abuts against the bottom of the support block to push the valve core upward as a whole, and the washing water enters the water outlet of the push rod 12 from the gap between adjacent support blocks.

[0093] Preferably, in this embodiment, the push rod 12 can also be configured to be axially telescopic. The stepper motor is installed below the accommodating cavity and is transmission-connected to the push rod 12. Specifically, the working end of the stepper electrode is arranged perpendicular to the push rod 12, and a crank block is installed on the working end of the stepper motor, and an eccentric shaft is arranged on the crank block, and the eccentric shaft is rotationally connected to the end of the push rod 12.

[0094] The crank block is a cylindrical structure, and the eccentric shaft is set at a position on the crank block that deviates from the central axis. When the stepper motor drives the crank block to rotate, the eccentric shaft performs eccentric rotational motion, and at the same time, the eccentric shaft and the push rod 12 rotate in coordination, thereby converting the eccentric motion of the eccentric shaft into linear motion of the push rod 12. The push rod 12 drives the valve core to move in the valve body to realize the opening and closing of the drain valve 35.

[0095] In this embodiment, the lower end of the push rod 12 is connected to the drainage pipeline. Specifically, the lower end of the water outlet of the push rod 12 is connected to the drainage pipeline through a telescopic tube, and the telescopic tube provides a margin for the axial reciprocating movement of the push rod 12.

[0096] A drainage pump or a negative pressure component is provided between the push rod 12 and the drainage pipeline, and the water and air in the barrel structure 3 are sucked by the drainage pump or the negative pressure component, so that the barrel wall of the barrel structure 3 shrinks, and the clothes in the barrel structure 3 are squeezed to achieve squeezing and dehydration. The pleated portion 31 provides a deformation margin for the shrinkage of the barrel wall.

[0097] In this embodiment, the negative pressure component includes a temporary storage chamber and an air pump. The temporary storage chamber is connected to the drain port 33. The input end of the air pump is connected to the temporary storage chamber from the top of the temporary storage chamber, and the output end of the air pump is connected to the external atmosphere. 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.

[0098] 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.
