Description

Technical Field

[0001] This invention belongs to the field of washing machine technology, and specifically relates to a pollution-proof washing machine. Background Technology

[0002] Existing washing machines typically have an inner tub and an outer tub. During washing, water is distributed between the inner and outer tubs, and the inner tub has several dewatering holes on its perimeter. For example, the pulsator washing machine and its lid described in patent publication number CN105297324A use a large amount of water during washing, resulting in water waste. Furthermore, because water is distributed between the inner and outer tubs, a larger amount of detergent is used, leading to detergent waste and hindering cost savings. Moreover, dirt easily accumulates between the inner and outer tubs, causing bacterial growth and requiring frequent disassembly and cleaning by the user, which is very inconvenient.

[0003] To address the aforementioned technical issues, a stain-free washing machine has been introduced to the market, such as the washing machine with patent publication number CN208121412U. This type of washing machine adopts a single-tub structure, that is, it only has a rotating tub and no water tank. In this way, the water is in the rotating tub during washing, which saves more water. A water guide is set on the inner peripheral wall of the rotating tub, with an inlet on the water guide and an outlet on the peripheral wall and / or bottom wall of the rotating tub. During spin-drying, the water in the rotating tub rises under the action of centrifugal force and enters the water guide through the inlet. Under the guidance of the water guide, it flows to the outlet and is discharged to the drip tray. Thus, while eliminating the water tank to simplify the structure, increase capacity, reduce dirt and bacteria growth, and save water, it can also improve the spin-drying effect.

[0004] However, the aforementioned patent document sets up a tub drainage channel and a tray drainage channel on the water receiving tray to achieve drainage through different channels for washing and spin-drying. However, there is no tight sealing structure between the tub drainage channel and the tray drainage channel in the aforementioned patent document, resulting in poor water sealing. This makes it difficult to achieve independent washing and spin-drying drainage. Furthermore, due to the poor sealing, it is also impossible to expand the functions of the stain-free washing machine, such as drying and boiling. Summary of the Invention

[0005] The purpose of this invention is to provide a pollution-proof washing machine. A water sealing plate and a sealing element are installed in the fixed base to separate the water receiving chamber and the water storage chamber, which enhances the water sealing performance of the drum and improves the air sealing performance of the drum. This achieves the independence of spin-drying drainage and washing drainage, and also facilitates the subsequent expansion of washing machine functions.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: a pollution-proof washing machine is proposed, comprising: an outer casing, which is provided with a drain pipe;

[0007] A rotating tank is rotatably disposed within the outer casing. The rotating tank includes a cylindrical body and a water guide cover. The upper part of the peripheral wall of the cylindrical body is provided with a plurality of water outlets along the circumferential direction. The water guide cover is coaxially sleeved on the outside of the cylindrical body. The upper end of the water guide cover is higher than the water outlets. A water guide cavity is formed between the cylindrical body and the water guide cover. Liquid rising in the cylindrical body due to centrifugal force enters the water guide cavity through the water outlets.

[0008] A rotating chassis is rotatably disposed within the outer casing. The lower end of the cylinder is sealed to the rotating chassis. The water guide cover is connected to the rotating chassis or the outer peripheral wall of the cylinder. The rotating chassis is provided with a first through hole that extends axially.

[0009] A barrel-shaped fixed base is provided, with the lower part of the rotating base and the lower end of the water guiding cavity both located within the fixed base. A water sealing plate is provided within the fixed base, dividing it into an upper and lower non-communicating water receiving cavity and a water storage cavity. The rotating base is located within the water receiving cavity. A tubular sealing element is provided between the first through hole and the water receiving cavity. The upper end of the sealing element is sealed to the rotating base, and the lower end of the sealing element is rotatably sealed to the water sealing plate. A second through hole is provided on the water sealing plate, and the first through hole and the second through hole are connected. The fixed base is provided with a first drainage channel and a second drainage channel. The first drainage channel is connected to the water receiving cavity, and the second drainage channel is connected to the water storage cavity. The second drainage channel is provided with a control valve for opening and closing the second drainage channel. Both the first drainage channel and the second drainage channel are connected to the drain pipe.

[0010] Compared with the prior art, the advantages of the present invention are as follows: In use, the second drain channel is closed, water is injected into the drum, and the water entering the drum enters the water storage chamber through the first and second through holes. Then, the water enters the second drain channel through the water storage chamber and fills the second drain channel. Then, the water level slowly rises and fills the drum. Then, the clothes are washed. After washing, the washing drain is performed first. During washing drain, the second drain channel is opened by the control valve, and the water is discharged from the drain pipe through the second drain channel. After washing drain, the spin-dry drain is performed. During spin-dry drain, the rotating base drives the rotating drum to rotate. The water on the clothes in the drum rises due to centrifugal force and enters the water guiding chamber through the water outlet. Then, it flows into the first drain channel through the water receiving chamber and is discharged from the drain pipe, completing the spin-drying.

[0011] This invention's anti-pollution washing machine achieves the goals of eliminating the water tank, simplifying the structure, increasing capacity, reducing dirt and bacterial growth, saving water, and improving spin-drying effect. Furthermore, the invention incorporates a water-sealing plate and sealing components within the fixed base, separating the water receiving chamber and the water storage chamber. This not only prevents pollution but also enhances the drum's sealing performance, achieving independent spin-drying and washing drainage. It also ensures that during washing, water will not enter the water receiving chamber from the storage chamber and then drain through the first drainage channel and drain pipe, guaranteeing the normal operation of the washing machine. The drum of this invention is connected to the second drainage channel only through a first and second through-hole, enhancing both the water-sealing and air-sealing performance of the drum. This type of sealing structure facilitates the subsequent expansion of the washing machine's functions, such as enabling boiling and drying.

[0012] In the aforementioned anti-pollution washing machine, a tubular connecting ring is connected to the lower end of the rotating chassis. The connecting ring is coaxially arranged with the first through hole. The water sealing plate is sleeved on the outside of the connecting ring through the second through hole. The sealing element is sealed between the water sealing plate and the connecting ring, and between the connecting ring and the rotating chassis. The side of the connecting ring that abuts against the water sealing plate is coated with sealant. The portion of the sealing element that seals between the connecting ring and the rotating chassis achieves a sealed connection between the connecting ring and the rotating chassis, and the portion of the sealing element that seals between the connecting ring and the water sealing plate achieves a sealed connection between the connecting ring and the water sealing plate, ensuring that the water storage chamber and the water receiving chamber are separated.

[0013] In the aforementioned anti-pollution washing machine, the tubular sealing element includes an integrally connected first sealing part, a vertical second sealing part, and a horizontal third sealing part. The lower end of the rotating chassis has downwardly extending guide blocks around the first through hole. The connecting pressure ring is sleeved on the outside of the guide blocks and connected to them. The upper end of the connecting pressure ring forms a "U"-shaped sealing groove with the guide blocks and the lower end of the rotating chassis. The vertical second sealing part is sleeved on the outside of the connecting pressure ring, and the first sealing part is sealed to the sealing groove. The lower end of the horizontal third sealing part is rotatably sealed to the water sealing plate. The sealing element, through the second sealing part sleeved on the outside of the connecting pressure ring, and the first connecting part of the sealing element connected to the "U"-shaped sealing groove, achieves a sealed connection between the rotating chassis, the guide hole, and the connecting pressure ring. The lower end of the third connecting part of the sealing element rotatably seals to the water sealing plate, achieving separation between the water storage chamber and the water receiving chamber.

[0014] In the above anti-pollution washing machine, the first sealing portion is in an inverted U shape, including a connected first sealing vertical block, a sealing horizontal block, and a second sealing vertical block. The first sealing vertical block is sealingly connected between the connecting pressure ring and the guiding block. The sealing horizontal block is sealingly connected between the rotating chassis and the connecting pressure ring. The rotating chassis is coaxially provided with a downwardly extending abutting vertical plate outside the guiding block. The second sealing vertical block is sealingly connected between the abutting vertical plate and the connecting pressure ring. The sealing horizontal block is pressed tightly between the rotating chassis and the connecting pressure ring. The sealing member is pressed tightly between the rotating chassis and the connecting pressure ring through the sealing horizontal block, connecting the sealing member to the lower end of the rotating chassis, so that the sealing member rotates together with the rotation of the rotating chassis, and the third sealing portion of the sealing member rotates and seals with the water sealing plate.

[0015] In the above anti-pollution washing machine, several coaxially arranged abutting blocks are provided at intervals at the lower end of the third sealing portion. The lower end surface of the abutting block abuts against the water sealing plate, and the abutting block realizes the sealing between the sealing member and the water sealing plate.

[0016] In the above anti-pollution washing machine, the lower end of the connecting pressure ring is provided with an inwardly extending connecting edge, and the connecting edge and the lower end of the rotating chassis are connected by bolts. During installation, the connecting pressure ring is sleeved outside the guiding block, and the connecting edge at the lower end of the connecting pressure ring is abutted against the lower end of the guiding block, and then the connecting edge and the lower end of the rotating chassis are connected by bolts. Thereby, the first connecting portion of the sealing member is pressed tightly between the connecting pressure ring and the rotating chassis.

[0017] In the above anti-pollution washing machine, the fixed seat is provided with connecting blocks along the circumferential direction. The lower end of the water sealing plate is provided with connecting grooves along the circumferential direction. The connecting grooves are connected to the connecting blocks, and a sealing ring is provided between the connecting grooves and the connecting blocks. The water sealing plate is sealingly connected to the connecting blocks of the rotating fixed seat, realizing the separation of the water storage cavity and the water receiving cavity.

[0018] In the above anti-pollution washing machine, a balance ring is connected to the upper end of the cylinder body, and an inner cover is connected to the balance ring. The inner cover is used to seal the upper opening of the cylinder body. The balance ring is used to ensure the balance during the rotation of the cylinder body. The inner cover provided on the cylinder body further improves the airtightness of the cylinder body, and ensures that water will not be thrown out from the upper opening of the cylinder body during dehydration, so as to ensure that all the water during dehydration enters the water guiding cavity through the water outlet, improving the water tightness during the dehydration of the cylinder body. And by providing an inner cover on the cylinder body, it can also reduce heat dissipation when realizing the functions of boiling and drying, and play a role in protecting the control components on the outer box body, avoiding damage to the controller by hot air, and the setting of the inner cover also plays a role in protecting the user.

[0019] In the aforementioned anti-pollution washing machine, the outer casing is provided with an outer cover, and several hanging rods are evenly distributed around the upper surface of the fixed base. One end of each hanging rod is connected to the top of the outer casing, and an elastic element is connected to the side of the hanging rod near the fixed base to provide shock absorption. Specifically, the elastic element is a spring, but other elastic components may also be used.

[0020] The aforementioned anti-pollution washing machine also includes a drive mechanism, which comprises a drive assembly, a drive shaft, and a pulsator. The fixed base has an axially penetrating third through hole. The third, second, and first through holes are all coaxially arranged. The drive assembly is connected to the drive shaft. One end of the drive shaft passes sequentially through the third, second, and first through holes and connects to the rotating base and the pulsator, respectively. The drive assembly, via the drive shaft, drives at least one of the rotating base and the pulsator to rotate. During washing, the drive assembly drives the pulsator to rotate via the drive shaft, washing the clothes inside the drum. During spin-drying, the drive assembly drives the rotating base to rotate via the drive shaft, thereby rotating the drum and spin-drying the clothes inside the drum. Attached Figure Description

[0033] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0034] like Figures 1-11 As shown, the present invention provides a pollution-proof washing machine, comprising: an outer casing 1, which includes an outer tub 40 with an opening at the upper end, a control seat 41 connected to the upper end of the outer tub 40, the control seat 41 having an opening, an outer cover 42 connected to the opening, a control panel 43 on the mounting base, a water inlet 44 and a water inlet channel on the control seat, and a water inlet pipe connected to the water inlet 44.

[0035] The rotating tank 3 is rotatably disposed inside the outer casing 1. The rotating tank 3 includes a cylinder 4 and a water guide 5. The upper end of the cylinder 4 is connected to the water injection channel. Several water outlets 6 are provided on the upper part of the circumferential wall of the cylinder 4. The water guide 5 is coaxially sleeved on the outside of the cylinder 4. The upper end of the water guide 5 is higher than the water outlets 6. A water guide cavity 7 is formed between the cylinder 4 and the water guide 5. The liquid rising in the cylinder 4 due to centrifugal force enters the water guide cavity 7 through the water outlets 6.

[0036] The rotating chassis 8 is rotatably disposed inside the outer casing 1. The lower end of the cylinder 4 is sealed to the rotating chassis 8. The water guide 5 is connected to the outer peripheral wall of the rotating chassis 8 or the cylinder 4. The rotating chassis 8 is provided with an axially penetrating first through hole 9, which communicates with the cylinder 4.

[0037] The lower part of the rotating base 8 and the lower end of the water guiding cavity 7 are both located inside the barrel-shaped fixed base 10. A water sealing plate 11 is provided inside the fixed base 10, which divides the fixed base 10 into an upper and lower non-connected water receiving cavity 12 and a water storage cavity 13. The rotating base 8 is located inside the water receiving cavity 12. A tubular sealing element 14 is provided between the first through hole 9 and the water receiving cavity 12. The upper end of the sealing element 14 is sealed to the rotating base 8, and the lower end of the sealing element 14 is rotatably sealed to the water sealing plate 11. A second through hole 15 is provided on the water sealing plate 11, and the first through hole 9 and the second through hole 15 are connected. The fixed base 10 is provided with a first drainage channel 16 and a second drainage channel 17. The first drainage channel 16 is connected to the water receiving cavity 12, and the second drainage channel 17 is connected to the water storage cavity 13. The second drainage channel 17 is provided with a control valve for opening and closing the second drainage channel 17. The control valve is electrically connected to the controller. Both the first drainage channel 16 and the second drainage channel 17 are connected to the drain pipe 2.

[0038] The drive mechanism includes a drive assembly 37, a drive shaft, and an impeller 39. A third through hole 48 is axially through the fixed base 10. The third through hole 48, the second through hole 15, and the first through hole 9 are all coaxially arranged. The drive assembly 37 is connected to the drive shaft 38. One end of the drive shaft 38 passes sequentially through the third through hole 48, the second through hole 15, and the first through hole 9, and is connected to the rotating base 8 and the impeller 39 respectively. The drive assembly 37 drives the rotation of at least one of the rotating base 8 and the impeller 39 via the drive shaft 38. The drive assembly 37 is electrically connected to the controller. During washing, the drive assembly 37 drives the impeller 39 to rotate via the drive shaft 38, washing the clothes inside the drum 4. During spin-drying, the drive assembly 37 drives the rotating base 8 to rotate via the drive shaft 38, thereby rotating the drum 4 and spin-drying the clothes inside the drum 4.

[0039] In use, the controller closes the second drain channel 17 via the control valve, and water is injected into the drum 4 through the water inlet 44 and the water inlet channel via the water inlet pipe. The water entering the drum 4 enters the water storage chamber 13 through the first through hole 9 and the second through hole 15, and then enters the second drain channel 17 through the water storage chamber 13 and fills the second drain channel 17. The water level then slowly rises and fills the drum 4. When the water level reaches the preset water level, the controller closes the water inlet 44 to stop water injection. Then the controller starts the drive assembly 37, which drives the impeller 39 to rotate via the drive shaft for washing. After washing, the drive assembly 37 stops the rotation of the impeller 39. Then, the washing and draining process begins. During washing and draining, the controller controls the control valve to open the second drain channel 17, and the water is discharged from the drain pipe 2 through the second drain channel 17 (e.g., Figure 4 (As indicated by the arrow) After washing and draining, spin-drying and draining are performed. During spin-drying and draining, the controller controls the drive assembly 37 to drive the rotating base 8 to rotate via the drive shaft. Simultaneously, the rotating base 8 drives the rotating drum 3 to rotate. Water on the clothes inside the drum 4 rises due to centrifugal force and enters the water guide chamber 7 through the water outlet 6. Then, it flows into the first drain channel 16 through the water receiving chamber 12 and is discharged from the drain pipe 2 (as shown by the arrow). Figure 3 (As shown by the arrow), dehydration is complete.

[0040] The anti-pollution washing machine of the present invention achieves the goals of eliminating the water tank, simplifying the structure, increasing capacity, reducing dirt and bacterial growth, saving water, and improving the dehydration effect. Furthermore, the present invention incorporates a water-sealing plate 11 and a sealing element 14 within the fixed base 10, separating the water receiving chamber 12 and the water storage chamber 13. This not only prevents pollution but also enhances the sealing performance of the drum 4, achieving independence between dehydration drainage and washing drainage. It also ensures that during washing, water will not enter the water receiving chamber 12 from the water storage chamber 13 and then be discharged through the first drainage channel 16 and the drain pipe 2, guaranteeing the normal operation of the washing machine. The drum 4 of the present invention is connected to the second drainage channel 17 only through the connecting first through hole 9 and second through hole 15, which not only enhances the water sealing performance of the drum 4 but also improves its air sealing performance. This type of sealing structure facilitates the subsequent expansion of the washing machine's functions, such as enabling boiling and drying.

[0041] In the present invention, a tubular connecting pressing ring 18 is connected to the lower end of the rotating chassis 8. The connecting pressing ring 18 is coaxially arranged with the first through hole 9. The water sealing plate 11 is sleeved outside the connecting pressing ring 18 through the second through hole 15. The sealing member 14 is hermetically arranged between the water sealing plate 11 and the connecting pressing ring 18 and between the connecting pressing ring 18 and the rotating chassis 8. A sealing glue is coated on one side of the connecting pressing ring 18 that abuts against the water sealing plate 11. The part where the sealing member 14 is hermetically connected between the connecting pressing ring 18 and the rotating chassis 8 realizes the sealing connection between the connecting pressing ring 18 and the rotating chassis 8. The part where the sealing member 14 is connected between the connecting pressing ring 18 and the water sealing plate 11 realizes the sealing connection between the connecting pressing ring 18 and the water sealing plate 11, ensuring the separation of the water storage cavity 13 and the water receiving cavity 12.

[0042] As some embodiments of the present invention, the tubular sealing member 14 includes an integrally connected first sealing portion 19, a vertical second sealing portion 20 and a horizontal third sealing portion 21. Guide blocks 22 extending downward are provided around the first through hole 9 at the lower end of the rotating chassis 8. The connecting pressing ring 18 is sleeved outside the guide blocks 22 and connected to the guide blocks 22. A "冂"-shaped sealing groove 23 is formed between the upper end of the connecting pressing ring 18, the guide blocks 22 and the lower end of the rotating chassis 8. The vertical second sealing portion 20 is sleeved outside the connecting pressing ring 18. The first sealing portion 19 is hermetically connected at the sealing groove 23. The lower end of the horizontal third sealing portion 21 is rotationally sealed with the water sealing plate 11. The sealing member 14 is sleeved outside the connecting pressing ring 18 through the second sealing portion 20. The first connecting portion of the sealing member 14 is connected in the "冂"-shaped sealing groove 23, realizing the sealing connection between the rotating chassis 8, the guide hole and the connecting pressing ring 18. The lower end of the third connecting portion of the sealing member 14 is rotationally sealed with the water sealing plate 11, realizing the separation of the water storage cavity 13 and the water receiving cavity 12.

[0043] Furthermore, the first sealing portion 19 is "冂"-shaped and includes connected first sealing vertical blocks 24, a sealing horizontal block 25 and second sealing vertical blocks 26. The first sealing vertical blocks 24 are hermetically connected between the connecting pressing ring 18 and the guide blocks 22. The sealing horizontal block 25 is hermetically connected between the rotating chassis 8 and the connecting pressing ring 18. An abutting vertical plate 27 extending downward is coaxially arranged outside the guide blocks 22 on the rotating chassis 8. The second sealing vertical blocks 26 are hermetically connected between the abutting vertical plate 27 and the connecting pressing ring 18. The sealing horizontal block 25 is pressed tightly between the rotating chassis 8 and the connecting pressing ring 18. The sealing member 14 is pressed tightly between the rotating chassis 8 and the connecting pressing ring 18 through the sealing horizontal block 25, connecting the sealing member 14 to the lower end of the rotating chassis 8, so that the sealing member 14 will rotate together with the rotation of the rotating chassis 8. The third sealing portion 21 of the sealing member 14 is rotationally sealed with the water sealing plate 11.

[0044] Furthermore, the lower end of the third sealing part 21 is provided with a plurality of coaxially arranged abutment blocks 28 at intervals. The lower end face of the abutment block 28 abuts against the water sealing plate 11, and the abutment block 28 achieves the sealing between the sealing member 14 and the water sealing plate 11.

[0045] Furthermore, the lower end of the connecting pressure ring 18 is provided with an inwardly extending connecting edge 29, which is bolted to the lower end of the rotating base 8. During installation, the connecting pressure ring 18 is sleeved on the outside of the guide block 22, and the connecting edge 29 at the lower end of the connecting pressure ring 18 abuts against the lower end of the guide block 22. Then, the connecting edge 29 is bolted to the lower end of the rotating base 8. This presses the first connecting part of the seal 14 between the connecting pressure ring 18 and the rotating base 8. In this invention, a water leakage plate 45 is coaxially provided at the lower end of the first through hole 9. The water leakage plate 45 is connected to the rotating base 8 around its perimeter. A plurality of water leakage holes 46 are evenly distributed along the circumferential direction on the water leakage plate 45. The water leakage plate 45 is also provided with a fourth through hole 47, through which one end of the drive shaft can pass.

The connecting groove 31 is connected to the connecting block 30, and a sealing ring 32 is provided between the connecting groove 31 and the connecting block 30. The water sealing plate 11 is sealed to the connecting block 30 of the rotating fixed base 10, thereby separating the water storage chamber 13 and the water receiving chamber 12.

[0047] In some embodiments of the present invention, a balance ring 33 is connected to the upper end of the cylinder 4, and an inner cover 34 is connected to the balance ring 33. The inner cover 34 is used to seal the upper opening of the cylinder 4. The balance ring 33 is used to ensure the balance of the cylinder 4 during rotation. The inner cover 34 on the cylinder 4 further improves the airtightness of the cylinder 4, and ensures that water will not be thrown out from the upper opening of the cylinder 4 during dehydration, thereby ensuring that all water enters the water guiding chamber 7 through the water outlet 6 during dehydration, improving the water tightness of the cylinder 4 during dehydration. Furthermore, the inner cover 34 on the cylinder 4 can also reduce heat loss when performing boiling and drying functions, and protects the control components on the outer casing 1, preventing damage to the controller from hot air. The inner cover 34 also protects the user.

[0048] In some embodiments of the present invention, a plurality of suspension rods 35 are evenly distributed around the upper surface of the fixed base 10. One end of each suspension rod 35 is connected to the top of the outer casing 1, and an elastic element 36 is connected to the side of the suspension rod 35 near the fixed base 10 to provide shock absorption. Specifically, the elastic element 36 is a spring, but other elastic elements may also be used.
