Technical Field

[0001] The utility model relates to the technical field of laundry equipment, in particular to a pulsator washing machine. Background Art

[0002] There are two types of pulsator washing machines on the market now: one is a semi-automatic pulsator washing machine. When dehydrating, it requires manual operation to add a dehydration basket into the laundry tub and move the clothes to the dehydration basket, or this semi-automatic pulsator washing machine is additionally provided with a dehydration tub, and the clothes are moved to the dehydration tub during dehydration. Such a washing machine has low automation and cumbersome operation; the other is a fully automatic pulsator washing machine. The laundry tub of this fully automatic pulsator washing machine includes an inner tub and an outer tub. The inner tub is fixedly installed in the inner cavity of the outer tub, so that a dehydration gap is formed between the inner tub and the outer tub. Dehydration holes are formed on the wall surface of the inner tub. During cleaning, the outer tub is used for storing water, and the inner tub is used for holding clothes. During dehydration, the water body in the inner tub enters the dehydration gap through the dehydration holes under the action of centrifugal force, so as to realize the fully automatic cleaning and dehydration operations of the washing machine. However, with the increase of the use time, it is easy to hide dirt and scale in the dehydration gap. And the inner tub of the existing fully automatic pulsator washing machine is an integrated structure, and the installation structure of the washing machine is relatively complex, resulting in difficulty for users to disassemble the inner tub by themselves. It is necessary for professional maintenance personnel to come to the door to disassemble the inner tub to clean the dehydration gap, and the daily maintenance cost is relatively high.

Detailed Description of the Embodiment

[0020] In order to have a clearer understanding of the technical features, objectives and effects of the present utility model, the specific embodiments of the present utility model will now be described in detail with reference to the accompanying drawings.

[0021] As Figures 1 to 3 A pulsator washing machine according to an embodiment includes a tub 1, a partition plate 2, a valve 4, and four dehydration baffles 3. The tub 1 is a cylindrical structure with an open upper end. The inner cavity of the tub 1 is divided into an upper water storage cavity and a lower water storage cavity 12 by the partition plate 2. The upper water storage cavity is communicated with the open upper end of the tub 1, and the lower water storage cavity 12 is communicated with an external drainage pipe through the valve 4. Each dehydration baffle 3 is an arc-shaped plate body, and a plurality of dehydration holes 31 are formed on each dehydration baffle 3. All the dehydration baffles 3 are detachably installed and fixed in the upper water storage cavity of the tub 1. All the dehydration baffles 3 are sequentially spliced end to end to form an inner tub with a cylindrical structure. The central axis of the inner tub is collinear with the central axis of the upper water storage cavity of the tub 1. A clothing storage space is formed by enclosing the inner side wall of the inner tub and the dehydration baffle 3. A dehydration gap 11 is formed between the outer side wall of the inner tub and the inner side wall of the tub 1. The dehydration gap 11 is communicated with the lower water storage cavity 12.

[0022] The working principle of this embodiment:

[0023] When it is necessary to clean the dehydration gap 11, after removing the connection structure between each dehydration baffle 3 and the tub 1, each dehydration baffle 3 can be separately withdrawn from the upper water storage cavity of the tub 1, and then the parts forming the dehydration gap 11 can be cleaned. Through the split structure of the inner tub formed by splicing a plurality of dehydration baffles 3, and the design that each dehydration baffle 3 can be separately detachably installed, the disassembly and installation of the inner tub of this pulsator washing machine are convenient, enabling the user to disassemble it by themselves for cleaning, and reducing the user's daily maintenance cost.

[0024] As Figure 2 And Figure 3As shown in the figure, a number of water pressing plate parts 32 are formed on the side of the dehydration baffle 3 facing the inner wall of the barrel body 1. The number of water pressing plate parts 32 are arranged in sequence along the arc center axis of the dehydration baffle 3. Each water pressing plate part 32 is a spiral plate body arranged around the arc center axis of the dehydration baffle 3. The side of each water pressing plate part 32 facing away from the dehydration baffle 3 is attached to the inner wall of the barrel body 1, and the spiral directions of each water pressing plate part 32 are the same; between every two adjacent dehydration baffles 3: the ends of the number of water pressing plate parts 32 of the two dehydration baffles 3 are butt-joined correspondingly, so that the dehydration gap 11 is divided into 4 dehydration channels 111 by the water pressing plate parts 32 of all the dehydration baffles 3. The 4 dehydration channels 111 are arranged in sequence around the central axis of the barrel body 1. The dehydration channel 111 is a spiral structure arranged around the central axis of the barrel body 1, and the bottom end of the dehydration channel 111 communicates with the lower water storage cavity 12. During dehydration, the valve 4 is switched to a state of communicating with the external drainage pipe, and the barrel body 1 rotates around its own axis. The water body in the clothes storage space enters the dehydration channel 111 through the dehydration holes 31 under the action of centrifugal force. The water pressing plate part 32 forming the upper side of the dehydration channel 111 is driven by the barrel body 1 to press down and convey the water body in the dehydration channel 111 to the lower water storage cavity 12, thereby improving the drainage efficiency of the dehydration gap 11 and the dehydration effect.

[0025] As Figures 1 to 3 shown, mounting holes are respectively formed at the four corner positions of each dehydration baffle 3. There are also a number of fixing screws 30. One fixing screw 30 corresponds to one mounting hole of all the dehydration baffles 3. One end of the fixing screw 30 passes through the mounting hole of the corresponding dehydration baffle 3 and is detachably connected and fixed to the barrel body 1. With such a structure, each dehydration baffle 3 is detachably connected to the barrel body 1 through 4 fixing screws 30. While ensuring a stable connection structure between the dehydration baffle 3 and the barrel body 1, it also makes the disassembly of the dehydration baffle 3 relatively convenient.

[0026] As Figure 2As shown, this embodiment further includes a base 20, a transmission wheel 5, a clutch 6, a wave wheel disc 7, a hollow rotating shaft 8, and a drive assembly 9; a central hole is formed at the center position of the partition plate 2; the wave wheel disc 7 is rotatably arranged in the central hole of the partition plate 2, the hollow rotating shaft 8 is rotatably arranged on the barrel 1, the upper end of the hollow rotating shaft 8 is fixedly connected and communicated with the wave wheel disc 7 from the lower water storage chamber 12, the lower end of the hollow rotating shaft 8 is communicated with an external drainage pipe, a sealing ring 40 is arranged between the hollow rotating shaft 8 and the barrel 1, a drainage hole 81 communicating with its inner cavity is formed on the outer peripheral surface of the hollow rotating shaft 8, and the drainage hole 81 is in the lower water storage chamber 12; the valve 4 is arranged in the inner cavity of the hollow rotating shaft 8, and the valve 4 is below the drainage hole 81. The transmission wheel 5 is rotatably arranged on the base 20, and the transmission wheel 5 is coaxially and fixedly connected with the hollow rotating shaft 8; the drive assembly 9 is used to drive the transmission wheel 5 to rotate; the barrel 1 is rotatably arranged on the base 20, the rotation axis of the barrel 1 is collinear with the rotation axis of the transmission wheel 5, and the barrel 1 and the transmission wheel 5 are connected by the clutch 6, so that the barrel 1 can be switched between a state of being fixedly connected with the transmission wheel 5 and a state of being separated from the transmission wheel 5 through the state switching of the clutch 6. The drive assembly 9 includes a drive motor 91, a drive wheel 92, and a belt 93. The drive wheel 92 is coaxially and fixedly connected to the output shaft of the drive motor 91, and the drive wheel 92 and the transmission wheel 5 are connected by the belt 93 for transmission. The valve 4 includes a fixed valve body 41, a movable valve body 42, a connecting rod 43, and a driver 44; the fixed valve body 41 is fixedly installed on the inner side wall of the hollow rotating shaft 8, and the fixed valve body 41 is below the drainage hole 81; one end of the connecting rod 43 is slidably inserted into the inner cavity of the hollow rotating shaft 8, and the other end of one end of the connecting rod 43 is connected to the driver 44; the driver 44 is used to drive the connecting rod 43 to perform telescopic actions; the movable valve body 42 is fixedly installed on the connecting rod 43, and the movable valve body 42 can be driven by the connecting rod 43 to cooperate with the fixed valve body 41 to block the inner cavity of the hollow rotating shaft 8.

[0027] During the laundry process, the driver 44 drives the movable valve body 42 to move through the connecting rod 43, so that the movable valve body 42 cooperates with the fixed valve body 41 to block the inner cavity of the hollow rotating shaft 8. The clutch 6 is in a separated state, so that the barrel 1 is separated from the transmission wheel 5. At this time, the drive motor 91 drives the transmission wheel 5 to rotate, which can only drive the hollow rotating shaft 8 to rotate and drive the wave wheel disc 7 to rotate, so as to clean the clothes in the clothes storage space.

[0028] When the laundry process is completed, the driver 44 drives the movable valve body 42 to move through the connecting rod 43, so that the movable valve body 42 is separated from the fixed valve body 41 to open the inner cavity of the hollow rotating shaft 8, and the water in the barrel 1 is discharged to the external drainage pipe under the action of gravity through the hollow rotating shaft 8; the clutch 6 is switched to the closed state, so that the barrel 1 is fixedly connected to the transmission wheel 5. At this time, the drive motor 91 drives the transmission wheel 5 to rotate to drive the barrel 1 to rotate, so that the water on the clothes is thrown into one of the dehydration channels 111 of the dehydration gap 11 under the action of centrifugal force. Driven by the barrel 1, the water pressing plate part 32 on the upper side of the dehydration channel 111 presses down and conveys the water in the dehydration channel 111 to the lower water storage chamber 12, and the water in the lower water storage chamber 12 is discharged to the external drainage pipe through the hollow rotating shaft 8.

[0029] As Figure 1 and Figure 2 shown, this embodiment further includes a balance ring 10. The balance ring 10 is installed on the upper end surface of the barrel 1. The balance ring 10 is a hollow ring structure, and the inner diameter of the balance ring 10 is larger than the diameter of the inner barrel. In actual use, the dehydration baffle 3 has a certain deformation ability, or there is a gap between every two adjacent dehydration baffles 3 instead of being closely joined together; when disassembling the dehydration baffle 3, first disassemble the fixing screws 30 on the dehydration baffle 3, then draw the dehydration baffle 3 horizontally towards the center position of the barrel 1, and then draw the dehydration baffle 3 vertically and pass it through the inner ring of the balance ring 10, so as to disassemble the dehydration baffle 3 for cleaning. In addition, the partition plate 2 is detachably installed on the inner wall of the barrel 1. When cleaning, after all the dehydration baffles 3 are disassembled, disassemble the partition plate 2, so that the entire inner cavity of the barrel 1 can be conveniently cleaned.
