Description

Technical Field

[0001] This invention relates to the field of washing machine technology, specifically to a vertical washing machine and its cleaning method. Background Technology

[0002] A washing machine is a household machine used for washing clothes. It typically consists of a washing tub, a motor, and laundry detergent or powder. The clothes are washed by placing them in the washing tub, adding an appropriate amount of detergent or powder, and then the motor drives the washing tub to rotate.

[0003] Chinese patent CN113631769B discloses a vertical washing machine, including an outer tub, a washing tub, and a pulsator. In at least one of the washing and rinsing processes, a stirring process, a spreading process, and a tub rotation process are performed in sequence. In the stirring process, the rotating blades rotate while water is stored in the washing tub, and the laundry in the washing tub is washed by stirring.

[0004] The vertical washing machine described in the above patent rubs the clothes by the flow of liquid during the washing process. However, the liquid flow is limited, and washing clothes by liquid means that too many clothes cannot be put in at one time. This results in a lower rubbing effect and lower washing efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a vertical washing machine and its cleaning method. By extending and retracting the hydraulic telescopic rod and outputting the output motor, the upper scrubbing plate can move laterally back and forth simultaneously, thereby improving the scrubbing effect and the cleaning effect of clothes, and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vertical washing machine, including a lower outer shell, an upper outer shell, an upper rubbing plate, a second connecting plate, a first connecting plate, and transverse guide strips on both sides of the first connecting plate. A hydraulic telescopic rod is located at the middle of one side of one of the transverse guide strips. Clamping blocks fixed by bolts are located on both sides of the middle of the upper part of the first connecting plate. A connecting rod is longitudinally arranged between the two clamping blocks.

[0007] Preferably, a fixing block is welded to the telescopic end of the hydraulic telescopic rod, and a longitudinal guide strip is provided at the front end of the outer side of the fixing block, and the outer side of the longitudinal guide strip is connected to the inner sliding groove of the fixing block.

[0008] Preferably, bolts are used to fix the first connecting plate, the second connecting plate and the upper rubbing plate. The four corners of the outer side of the first connecting plate are provided with limiting blocks for fixing. There are two transverse guide strips. The two ends of the two transverse guide strips are welded with limiting rings. One side of the limiting block is slidably connected to the inside of the limiting ring.

[0009] Preferably, one end of the connecting rod is provided with an output motor for output, and the connecting rod is located on one side of the center position of the output shaft of the output motor.

[0010] Preferably, the lower end of the longitudinal guide bar is connected to the outer sliding groove of the transverse guide bar through a first limiting bar, and a second limiting bar is provided at each of the four corners of the outer side of the clamping block. The second limiting bar groove is connected to the transverse guide bar, and the inside of the second limiting bar is connected to the outer sliding groove of the transverse guide bar.

[0011] Preferably, a lower scrubbing plate is provided at the upper end of the interior of the lower outer casing of the washing machine. The lower scrubbing plate is made of expandable soft rubber. A dividing plate for dividing the area is provided at the lower end of the lower scrubbing plate. A liquid retention cavity is provided between the lower end of the dividing plate and the upper end of the lower outer casing of the washing machine. A drain outlet is provided in a ring shape on the outside of the lower scrubbing plate.

[0012] Preferably, a gas filling cavity is provided between the upper end of the dividing plate and the lower end of the lower kneading plate, and a gas flushing and releasing pump is provided in the middle position on the other side of the lower outer shell of the washing machine. The outlet of the gas flushing and releasing pump is sealed to the inside of the gas filling cavity through a gas transmission pipe.

[0013] Preferably, the interior of the second connecting plate and the upper kneading plate are both provided with through holes arranged in an array. The upper end of the first connecting plate is provided with a pipe connection end for transmitting and connecting liquid. A water inlet valve is provided on one side of the lower end of the interior of the washing machine. The water outlet end of the water inlet valve is sealed to the pipe connection end through a first liquid transmission pipe. The first liquid transmission pipe passes through the connecting shaft position of the upper and lower outer shells of the washing machine and enters the interior of the upper outer shell of the washing machine.

[0014] Preferably, a fixing frame is provided to seal one end of the first liquid transfer pipe.

[0015] The cleaning method for a top-loading washing machine includes the following steps:

[0016] Step 1: Unfold the upper outer shell of the washing machine to the upper part of the lower outer shell of the washing machine. After unfolding to expose the lower washboard, lay the clothes flat on the upper part of the lower washboard.

[0017] Step 2: Place the laundry detergent and powder for washing clothes in the fixed frame beforehand. The water inlet valve draws in the external liquid and transmits it through the first liquid transmission pipe. After the first liquid transmission pipe transmits the liquid to the fixed frame, it comes into contact with the pre-placed laundry detergent and powder, so that the liquid and laundry detergent and powder flow into the lower end of the first connecting plate.

[0018] Step 3: The through holes in the second connecting plate at the lower end of the first connecting plate and the upper scrubbing plate itself will allow the transmitted liquid, as well as laundry detergent and washing powder, to flow between the upper scrubbing plate and the lower scrubbing plate.

[0019] Step 4: The output shaft of the output motor drives the connecting rod to rotate around the output shaft of the output motor. The rotation can push the clamping blocks on both sides in turn. After the clamping blocks are restricted by the connecting rod, they will drive the upper kneading plate connected to the lower end to move back and forth laterally, so that the movement can be stable during the lateral back and forth movement.

[0020] Step 5: The hydraulic telescopic rod extends and retracts at the same frequency at regular intervals. The extension and retraction position of the hydraulic telescopic rod will drive the fixed block to move back and forth laterally. The inclination position inside the fixed block restricts the inclination position of the longitudinal guide bar, which can drive the upper kneading board, which moves back and forth laterally, to move back and forth longitudinally.

[0021] Step 6: The gas flushing and releasing pump starts on a timer and fills the gas filling chamber with gas through the gas transmission pipe. The gas flushing and releasing pump starts on a timer and extracts gas from the gas filling chamber through the gas transmission pipe. The lower rubbing board will adjust the position of the clothes as the gas volume decreases.

[0022] Step 7: The liquid between the upper and lower kneading boards will flow through the drain outlet into the liquid retention chamber. The liquid inside the liquid retention chamber will flow through the second liquid transmission pipe due to its weight and pass through the drain valve to complete the timed drainage.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. The washing machine of the present invention uses the extension and retraction of the hydraulic telescopic rod and the start of the output motor to drive the fixed block to move back and forth laterally, and drive the connecting rod to rotate around the output motor. Then, through the restriction of the horizontal guide bar and the limiting block, the upper rubbing plate can move back and forth longitudinally and laterally at the same time during rubbing. The rubbing of the upper rubbing plate, combined with the lower rubbing plate that expands due to gas, actively contacts the clothes and completes the rubbing of the clothes, improving the rubbing efficiency and rubbing effect.

[0025] 2. In this invention, when liquid is used and transported into the device, the extension of the first liquid transmission pipe and the restriction and connection of the pipe connection end allow the external liquid drawn by the water inlet valve to flow from the upper end of the washing machine to the lower end of the washing machine. Combined with the liquid retention chamber between the dividing plate and the lower outer shell of the washing machine, the liquid that has been in contact with the clothes being rubbed will carry the foreign matter generated by rubbing into the liquid retention chamber. Because of the reserved liquid retention chamber, the liquid at the upper part of the lower rubbing plate will preferentially contact the new liquid flowing in from the pipe connection end, preventing foreign matter generated by rubbing from continuing to soak around the clothes, avoiding repeated rubbing, reducing the damage rate of clothes, and improving rubbing efficiency and washing efficiency of clothes.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] To address the problems of existing technologies that rely on liquid flow for washing clothes, which suffer from limited liquid flow and low washing efficiency due to the limited amount of clothes that can be washed at once and the relatively low washing effect, this embodiment provides the following technical solution:

[0037] A vertical washing machine includes a lower outer casing 2, and an upper outer casing 1 is disposed at the upper end of the lower outer casing 2, such as... Figure 1 and Figure 2 As shown, the lower outer casing 2 and the upper outer casing 1 of the washing machine are rotatably connected on one side by a connecting shaft. The rotatable connection allows the upper outer casing 1 of the washing machine to be opened due to rotation, and clothes can be taken out and put into the device.

[0038] In this embodiment, as Figure 2 and Figure 3 As shown, a lower rubbing plate 6 is provided at the upper end of the interior of the lower outer shell 2 of the washing machine. During the placement and rubbing of clothes, the lower end of the clothes contacts the lower rubbing plate 6. An upper rubbing plate 5 is provided at the lower end of the interior of the upper outer shell 1 of the washing machine. During the placement and rubbing of clothes, the upper end of the clothes contacts the upper rubbing plate 5. The clamping of the upper rubbing plate 5 and the lower rubbing plate 6 can complete the washing of clothes.

[0039] In this embodiment, a second connecting plate 21 is provided at the upper end of the upper kneading board 5, and a first connecting plate 20 is provided at the upper end of the second connecting plate 21. A limiting block 30 for fixing is provided at each of the four corners of the outer surface of the first connecting plate 20, such as... Figure 3 and Figure 5 Bolts are used to fix the first connecting plate 20, the second connecting plate 21 and the upper kneading plate 5 through the bolts, while the other side of the limiting block 30 is fixed to the inner wall of the upper outer shell 1 of the washing machine by bolts.

[0040] In this embodiment, as Figure 5 and Figure 6 As shown, both sides of the first connecting plate 20 are provided with transverse guide bars 18. A hydraulic telescopic rod 24 is provided at the middle position of one side of one of the transverse guide bars 18. The hydraulic telescopic rod 24 performs transverse reciprocating movement at a predetermined time and speed. A fixing block 16 is welded to the telescopic end of the hydraulic telescopic rod 24. A longitudinal guide bar 17 is provided at the front end of the fixing block 16. The exterior of the longitudinal guide bar 17 is connected to the interior sliding groove of the fixing block 16. The cross-section of one side of the fixing block 16 is inclined at 45 degrees. The 45-degree inclined fixing block 16 can push the longitudinal guide bar 17. The lower end of the longitudinal guide bar 17 is connected to the outer sliding groove of the transverse guide bar 18 through the first limiting bar 23. The first limiting bar 23 continuously slides outside the transverse guide bar 18, so that when the fixing block 16 restricts the longitudinal guide bar 17 and causes longitudinal reciprocating movement, the fixing block 16 will pull the transverse guide bar 18 connected to the first connecting plate 20 to move longitudinally reciprocatingly through the first limiting bar 23. Due to the extension and retraction of the hydraulic telescopic rod 24, the fixing block 16, together with the restriction of the fixing block 16 and the first limiting bar 23, can drive the first connecting plate 20 to move longitudinally reciprocatingly.

[0041] In this embodiment, as Figure 3 and Figure 8 As shown, there are two transverse guide bars 18. Each end of the two transverse guide bars 18 is welded with a limiting ring 29. There are four limiting rings 29. The limiting rings 29 are located on one side outside the limiting block 30. The inside side of the limiting block 30 is slidably connected to the inside of the limiting ring 29. The upper kneading board 5 can move back and forth smoothly in the longitudinal direction by the limitation of the limiting block 30.

[0042] In this embodiment, clamping blocks 28, fixed by bolts, are provided on both sides of the upper middle of the first connecting plate 20. A connecting rod 26 is longitudinally arranged between the two clamping blocks 28. One end of the connecting rod 26 is provided with an output motor 25 for output. The connecting rod 26 is located on one side of the center position of the output shaft of the output motor 25. Figure 8As shown, the output shaft of the output motor 25 is welded and fixed to one end of the connecting rod 26. The output motor 25 is located in the middle position on one side of another horizontal guide bar 18. After the output of the output motor 25 drives the connecting rod 26 to rotate, the rotation of the connecting rod 26 will push the clamping block 28 and the horizontal line of the upper kneading plate 5 connected at the lower end to move back and forth.

[0043] In this embodiment, as Figure 5 and Figure 6 As shown, a second limiting strip 32 is provided at each of the four corners of the clamping block 28. The slot connection position of the second limiting strip 32 faces the horizontal guide strip 18. The inside of the second limiting strip 32 is connected to the external sliding slot of the horizontal guide strip 18. The lower end of the second limiting strip 32 is fixedly connected to the upper end of the first connecting plate 20 by bolts.

[0044] In this embodiment, wrapping strips 19 are provided at both the front and rear ends of the upper end of the first connecting plate 20. One end of the wrapping strip 19 is fixedly connected to the front and rear ends of the upper end of the first connecting plate 20 by bolts, such as... Figure 3 , Figure 5 and Figure 8 As shown, the other end of the wrapping strip 19 is fixedly connected to the inner wall of the upper outer shell 1 of the washing machine by bolts. The connection on both sides of the wrapping strip 19 can prevent the liquid inside the upper scrubbing plate 5 and the lower scrubbing plate 6 from flowing into the interior of the upper outer shell 1 of the washing machine.

[0045] In this embodiment, as Figure 3 , Figure 5 and Figure 8 As shown, the interior of the second connecting plate 21 and the upper kneading plate 5 are both provided with through holes in an array, and the upper end of the first connecting plate 20 is provided with a pipe connection end 27 for transmitting and connecting liquid.

[0046] In this embodiment, a water inlet valve 4 is provided on one side of the lower end of the inner casing 2 of the washing machine. The water inlet end of the water inlet valve 4 contacts the externally connected pipe, and the water outlet end of the water inlet valve 4 is sealed to the pipe connection end 27 through a first liquid transmission pipe 13. The first liquid transmission pipe 13 passes through the connecting shaft between the upper casing 1 and the lower casing 2 of the washing machine and enters the interior of the upper casing 1 of the washing machine. Figure 3 As shown, a fixed frame 14 is provided at one end of the first liquid transmission pipe 13. The liquid transmitted by the first liquid transmission pipe 13 will flow into the fixed frame 14. Laundry detergent and laundry powder can be placed in the fixed frame 14 in advance. The liquid will drive the laundry detergent and laundry powder to flow, flow and pass through the through holes of the array inside the second connecting plate 21, and flow from the upper end of the washing machine to the lower end of the washing machine to flow with liquid mixed with laundry detergent.

[0047] In this embodiment, as Figure 3 , Figure 4 and Figure 5As shown, the lower rubbing plate 6 is made of expandable soft rubber. The lower end of the lower rubbing plate 6 is provided with a dividing plate 10 for dividing the area. A liquid retention chamber 11 is provided between the lower end of the dividing plate 10 and the upper end of the lower outer shell 2 of the washing machine. A drain outlet 7 is provided in a ring shape on the outside of the lower rubbing plate 6. The drain outlet 7 penetrates the lower outer shell 2 of the washing machine and extends to the liquid retention chamber 11. The liquid between the upper rubbing plate 5 and the lower rubbing plate 6 will flow into the liquid retention chamber 11 through the drain outlet 7. Clothes in contact with the rubbing process will be directly discharged into the liquid retention chamber 11 through the drain outlet 7.

[0048] In this embodiment, a drain valve 3 is provided at the front end of the inlet valve 4, such as... Figure 5 and Figure 7 The interior of the liquid retention chamber 11 is sealed to the water drain valve 3 through the second liquid transmission pipe 22, which can directly draw out and discharge the liquid in the washing machine.

[0049] In this embodiment, as Figure 3 and Figure 7 As shown, a gas filling chamber 12 is provided between the upper end of the dividing plate 10 and the lower end of the lower rubbing plate 6. A gas flushing and releasing dual-purpose pump 8 is provided in the middle of the other side of the lower outer shell 2 of the washing machine. The gas outlet of the gas flushing and releasing dual-purpose pump 8 is sealed to the inside of the gas filling chamber 12 through a gas transmission pipe 9. When the gas transmission pipe 9 is sealed, it will pass through the liquid retention chamber 11. The gas conveyed and discharged by the gas flushing and releasing dual-purpose pump 8 will cause the lower rubbing plate 6 to expand periodically, actively pushing the clothes on the upper end of the lower rubbing plate 6 to rub.

[0050] In this embodiment, an internal bracket 31 is provided on one side of the output shaft of the output motor 25. The internal bracket 31 is used to support the output motor 25. The two sides of the output motor 25 are fixedly connected to the upper end of the inner casing 1 of the washing machine by bolts. Figure 8 As shown, the upper end of one side of the internal support 31 is supported by the first liquid transfer pipe 13.

[0051] The working principle of this invention is as follows:

[0052] The upper outer casing 1 of the washing machine rotates clockwise, unfolding at the upper end of the lower outer casing 2. After unfolding, the lower washboard 6 is exposed. Clothes are then laid flat on the upper end of the lower washboard 6. The upper outer casing 1 rotates counter-clockwise, resetting and covering the upper end of the lower outer casing 2. The water inlet valve 4 is activated, and laundry detergent and powder are pre-placed in the fixed frame 14. The water inlet valve 4 draws in external liquid and transmits it through the first liquid transmission pipe 13. Upon reaching the fixed frame 14, the first liquid transmission pipe 13 contacts the pre-placed laundry detergent and powder. Driven by the water flow, the liquid, detergent, and powder are agitated. The liquid flows into the lower end of the first connecting plate 20; the through holes of the second connecting plate 21 at the lower end of the first connecting plate 20 and the upper scrubbing plate 5 itself allow the transmitted liquid, as well as laundry detergent and washing powder, to flow between the upper scrubbing plate 5 and the lower scrubbing plate 6, flowing into and contacting the liquid placed inside; the output motor 25 is started, and the output shaft of the output motor 25 drives the connecting rod 26 to rotate around the output shaft of the output motor 25. The rotation can push the clamping blocks 28 on both sides in sequence. After the clamping blocks 28 are restricted by the connecting rod 26, they will drive the upper scrubbing plate 5 connected at the lower end to move laterally back and forth. During the lateral back and forth movement, the sliding groove of the first limiting strip 23 and the lateral guide strip 18 connects to... The second limiting strip 32 and the transverse guide strip 18 are connected by sliding slots to restrict movement, ensuring stable movement during transverse reciprocating motion. The hydraulic telescopic rod 24 is activated, extending and retracting at the same frequency. The extension and retraction of the hydraulic telescopic rod 24 drives the fixed block 16 to move laterally. The inclination of the fixed block 16 restricts the inclination of the longitudinal guide strip 17, causing the upper kneading plate 5 to move longitudinally. During longitudinal reciprocating motion, the limiting ring 29 slides within the limiting block 30 to restrict movement, ensuring stable movement. The gas flushing pump 8 is activated periodically. Gas is pumped into the gas filling chamber 12 through the gas transmission pipe 9. The gas volume in the gas filling chamber 12 increases, causing the lower rubbing plate 6 to expand. The expansion of the lower rubbing plate 6 forces the clothes to contact the upper rubbing plate 5. The gas flushing pump 8 is started at regular intervals and gas is extracted from the gas filling chamber 12 through the gas transmission pipe 9. The lower rubbing plate 6 will adjust the position of the clothes due to the decrease in gas volume. The drain valve 3 is opened at regular intervals. The liquid between the upper rubbing plate 5 and the lower rubbing plate 6 will flow into the liquid retention chamber 11 through the drain outlet 7. The liquid in the liquid retention chamber 11 will flow through the second liquid transmission pipe 22 due to its weight and pass through the drain valve 3 to complete the timed drainage.
