Description

Technical Field

[0001] This invention relates to the field of washing machine technology, and in particular to a squeeze adsorption washing device and its control method. Background Technology

[0002] Currently, washing machines are mainly divided into drum washing machines and top-loading washing machines. Drum washing machines mainly rely on lifting and tumbling action to wash clothes, while top-loading washing machines rely on the agitator blades to stir the clothes or water flow to make the clothes rub against the drum wall. Some squeeze washing devices only have single-sided squeeze washing, and the clothes are not tumbled or stirred during the washing process. These washing methods not only easily cause clothes to deform or wear and tear, but also consume relatively more water.

[0003] In common squeeze-washing devices, stains that have been removed during the squeeze-washing process are not drained in time. Some stains remaining in the wash water are then re-attached to the clothes, affecting the washing and rinsing results. When using a conventional squeeze-washing method for dehydration, water can only be drained through the drain outlet. This means that water that is not drained in time can easily be drawn back onto the clothes, reducing dehydration efficiency.

[0004] Patent publication number CN104975461A discloses a control method, a control method for a reciprocating piston washing machine, and a washing machine. The method controls the piston to move upward and squeeze to perform washing. It detects whether the piston has reached the limit position by current detection or limit switch. However, this detection method requires the piston to press against the clothes and generate force before the current changes and can be detected, which cannot reduce the wear and tear on the clothes. Moreover, it can only move back and forth between two limit positions, the movement distance is relatively long, and each round trip takes a relatively long time, resulting in simple control. In addition, its circulating water is sprayed from top to bottom instead of from bottom to top, so it does not have an agitation effect. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this invention is to provide a squeezing adsorption washing device and its control method, which solves the problems of some washing control methods that can only move back and forth between two extreme positions, the large squeezing washing stroke leading to long time consumption and reduced effective squeezing time, single control, uneven washing and excessive local wear caused by the clothes not moving during the squeezing washing process, and low dehydration efficiency due to the failure to drain water in time when using squeezing dehydration method.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a squeeze adsorption washing device, including an outer cylinder and an inner cylinder, wherein an adsorption device and a rotating lifting mechanism are provided above the inner cylinder, and a spraying device is provided at the bottom of the inner cylinder;

[0007] The bottom of the adsorption device is equipped with an adsorption element for adsorbing stains from washed clothes;

[0008] The rotating lifting mechanism is used to control the adsorption device to be in a set position, drive it to perform up and down squeezing motion in the vertical direction at a set frequency to wash clothes, and rotate to spin water after reaching a specified height to remove stains from the inner drum.

[0009] The spraying device is used to spray and agitate the clothes in the inner drum during the washing process. It includes a water inlet pipe, a circulation pump and several spray holes. The water outlet of the water inlet pipe is located above the inner drum for water to enter the inner drum. A branch pipe is connected to the water inlet pipe and is connected to the circulation pump through the branch pipe. The several spray holes are inclined at the bottom of the inner drum and the circulation pump is located on the branch pipe.

[0010] As a further improvement of the present invention: the rotating lifting mechanism includes a main shaft, a sleeve component, a rotating rod, a driving device, and a conversion component. The sleeve component is movably sleeved on the outer periphery of the main shaft. The sleeve component is fixedly connected to the adsorption device. A matching rod is provided on the upper end of one side of the outer periphery of the sleeve component. The rotating rod is installed near the upper end of the upper side of the outer periphery of the sleeve component.

[0011] As a further improvement of the present invention: the conversion component is installed between the drive device and the main shaft, the conversion component is connected to a first rotating wheel, and the upper end of the rotating rod is provided with a second rotating wheel. When the adsorption device moves up and down, the conversion component is connected to the first rotating wheel, the first rotating wheel and the second rotating wheel are connected by a belt, and the conversion component is disconnected from the main shaft.

[0012] As a further improvement of the present invention: when the adsorption device rotates, the driving device is connected to the main shaft through a conversion component, and the conversion component is disconnected from the first rotating wheel.

[0018] S1035: Control the adsorption device to press and adsorb for a preset time T1 at a set frequency within a preset distance range L, then proceed to S1036, where the set frequency is the ratio of the lifting time to the pressing time of the adsorption device.

[0023] S10310: Perform a logical judgment on whether the execution distance L3 and the preset distance Li3 satisfy L3≥Li3. If L3≥Li3, proceed to S10312. The preset distance Li3 is when the upper end face of the adsorption device is lower than the upper end face of the inner cylinder.

[0024] S10312: Control the adsorption device to stop moving for a preset time T3, then proceed to S10313;

[0025] S10313: Detect the water level in the inner cylinder and determine whether the current water level W and the low water level value W1 satisfy W≥W1. If W≥W1, proceed to S10315.

[0026] S10315: Turn on the circulation pump to spray water onto the clothes from the spray hole at the bottom of the inner drum for a preset time T4, so that the clothes are turned over.

[0027] S10316: Perform a squeezing and washing cycle and determine whether the cycle number n and the preset value K satisfy n≥K; if n≥K, the main washing process ends; if n<K, steps S1032~S10316 are executed again. Each execution increments the corresponding cycle number n by 1 until n≥K is satisfied, and the cycle ends.

[0028] As a further improvement of the present invention, the spray rinsing process specifically includes:

[0029] S1052: Controls the rising distance L4 of the adsorption device;

[0030] S1053: Determine whether the preset distance L4 and the preset distance Li4 satisfy L4≥Li4. If L4≥Li4, go to S1055.

[0031] S1055: Stop the movement of the adsorption device for a preset time T5, then proceed to S1056;

[0032] S1056: Controls the opening of the inlet valve and drain valve of the water inlet pipe, allowing water to enter from the top of the inner cylinder while spraying and draining simultaneously for a preset time T6.

[0033] As a further improvement of the present invention, the final dehydration process specifically includes:

[0034] S1062: Driving adsorption device to descend distance L1;

[0035] S1063: Determine whether the distance L1 and the preset distance Li1 satisfy L1≥Li1. If L1≥Li1, go to S1065.

[0036] S1065: Control the adsorption device to squeeze and adsorb for a preset time T7, then switch to S1066 to squeeze out the residual moisture on the clothes. Some of the water is discharged through the drain outlet, and some of the water is absorbed into the adsorption element.

[0037] S1066: Controls the adsorption device to rise a preset distance L2;

[0038] S1067: Determine whether the distance L2 and the preset distance Li2 satisfy L2≥Li2. If L2≥Li2, go to S1069.

[0040] S10610: Determine the number of cycles for extrusion adsorption dehydration. Determine if the number of cycles m satisfies the preset value K1: m≥K1; if m≥K1, proceed to S10611; if m<K1, repeat S1062~S10610, increasing the value of m by 1 for each execution.

[0041] S10611: Drain the water between the inner and outer cylinders.

[0042] As a further improvement of the present invention: the preset distance Li1 is determined according to the inner diameter of the inner cylinder and the amount of clothing.

[0043] As a further improvement of the present invention: the distance of the adsorption device is determined by a sensor on the guide rod.

[0044] Compared with the prior art, the beneficial effects of the present invention are:

[0045] 1. In the apparatus and method of the present invention, on the one hand, after the adsorption device descends to meet the set distance, it performs squeezing adsorption washing at a certain rhythmic frequency within a limited short distance area. The movement amplitude is small, which can shorten the up-and-down movement of the adsorption device, reduce the washing control time, and increase the effective squeezing washing time. On the other hand, after the adsorption device rises to meet the set distance, it controls the adsorption device to stop moving up and down, and then rotates to throw off the dirt or sewage on the adsorption device, which helps with washing and rinsing.

[0046] 2. After the adsorption device detects that it has descended to the set distance, the present invention then performs water level detection. Based on the detected water level information, it controls the circulation pump to perform a water spraying and agitation action or controls the water inlet valve to perform a water replenishment operation. Specifically, when the water level meets the pump's working water level, the circulation pump is controlled to spray water onto the clothes above, agitating them, which helps to wash the clothes evenly and reduce local wear.

[0047] 3. After the adsorption device descends to a set distance, it squeezes out the residual water on the clothes and absorbs the water onto the adsorption element. Then, after the adsorption device rises to a set distance, it rotates at high speed to throw off the water on the adsorption element. This way, the squeezed-out water is carried away in time, avoiding back absorption and improving the dehydration efficiency. Attached Figure Description

[0058] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0059] In order to solve the technical problems in the prior art, the present invention will now be further described in conjunction with the accompanying drawings and embodiments: Example

[0060] like Figures 1-4 As shown, this embodiment discloses a squeeze adsorption washing device, including an outer cylinder 1 and an inner cylinder 2. The inner cylinder 2 is located inside the outer cylinder 1, and the upper end face of the inner cylinder 2 is lower than the upper end face of the outer cylinder 1. The inner cylinder 2 is used to hold laundry 12. An adsorption device 42 and a rotating lifting mechanism are provided above the inner cylinder 2. The adsorption device 42 is used to adsorb the stains on the laundry 12. After the adsorption device 42 is controlled to be in a set position by the rotating lifting mechanism, it is driven to perform up and down squeezing motion in the vertical direction at a set frequency to wash the laundry 12. After reaching a specified height, it rotates and spins water to throw the stains away from the inner cylinder 2, thus solving the problem of low dehydration efficiency caused by the failure to discharge water in time when using the squeeze dehydration method.

[0061] It is also equipped with a spray device to spray the clothes 12 in the inner drum 2 during the washing process, so as to avoid uneven washing and excessive local wear caused by squeezing the clothes 12 without moving during the washing process.

[0062] The spraying device includes an inlet pipe 15, a circulation pump, and several spray holes 14. The outlet of the inlet pipe 15 is located above the inner cylinder 2 for water to enter the inner cylinder 2. The inlet pipe 15 is used to enter the inner cylinder 2. A branch pipe 16 is connected to the inlet pipe 15 and is connected to the circulation pump through the branch pipe 16. The several spray holes 14 are inclined at the bottom of the inner cylinder 2, and the circulation pump is located on the branch pipe 16.

[0063] The outlet of the water inlet pipe 15 is connected to a spray unit 11.

[0064] Preferably, both the outer cylinder 1 and the inner cylinder 2 are circular containers.

[0065] Preferably, the rotating lifting mechanism includes a main shaft 5, a sleeve component 4, a rotating rod 6, a driving device 7, and a conversion component 8. The sleeve component 4 is movably sleeved on the outer periphery of the main shaft 5 and is fixedly connected to the adsorption device 42. A matching rod 45 is provided on the upper end of one side of the outer periphery of the sleeve component 4. The rotating rod 6 is installed near the upper end of one side of the outer periphery of the sleeve component 4. A spiral recessed sliding track 61 is provided on the outer periphery of the rotating rod 6 in the vertical direction. The matching rod 45 is embedded in the recessed sliding track 61 for cooperation. The matching rod 45 moves in the recessed sliding track 61 to realize the vertical up and down movement of the adsorption device 42.

[0066] More preferably, the conversion component 8 is installed between the drive device 7 and the main shaft 5 to switch between the up-and-down movement state and the circumferential rotation state of the adsorption device 42. The conversion component 8 is connected to a first rotating wheel 81, and a second rotating wheel 62 is provided at the upper end of the rotating rod 6.

[0067] More preferably, when the adsorption device 42 needs to move up and down, the conversion component 8 is connected to the first rotating wheel 81, and the first rotating wheel 81 is connected to the second rotating wheel 62 via a belt 9. At this time, the conversion component 8 is disconnected from the main shaft 5. The main shaft 5 and the sleeve component 4 cooperate to form a sliding and telescopic mechanism. Through the cooperation of the drive device 7, the first rotating wheel 81, the belt 9, and the second rotating wheel 62, the rotating rod 6 is driven to rotate, thereby causing the sleeve component 4 to move up and down along the axial direction of the main shaft 5.

[0068] More preferably, when the adsorption device 42 / main shaft 5 needs to rotate, the drive device 7 is connected to the main shaft 5 through the conversion component 8. At this time, the conversion component 8 is disconnected from the first rotating wheel 81.

[0069] In other words, when the main shaft 5 rotates, the first rotating wheel 81 does not rotate, and when the main shaft 5 does not rotate, the first rotating wheel 81 rotates. The main shaft 5 and the first rotating wheel 81 cannot be connected to the conversion component 8 at the same time. Therefore, the main shaft 5 and the first rotating wheel 81 will not rotate at the same time, ensuring that the adsorption device 42 can stop at a certain position to perform dehydration operation.

[0070] More preferably, a protruding limiting block 51 is provided at one end of the main shaft 5 near the adsorption device 42, and a limiting groove 47 that cooperates with the limiting block 51 is provided on the inner cavity of the sleeve component 4. This is used to ensure that the sleeve component 4 moves along the axial direction of the main shaft 5, and also to enable the main shaft 5 to drive the sleeve component 4 to rotate. It also has a limiting function to prevent the sleeve component 4 from coming off the main shaft 5.

[0071] More preferably, a bearing 44 is connected to the upper outer periphery of the sleeve component 4. One end of the bearing 44 is connected to the mating rod, and the other end of the bearing 44 is connected to the positioning wheel 46. A guide rod 10 is provided near the other side of the sleeve component 4. The guide rod 10 is provided with a positioning sliding track in the vertical direction, and the positioning wheel 46 is embedded in the positioning sliding track for mating.

[0072] When the rotating rod 6 rotates, the mating rod 45 moves up and down along the recessed sliding track 61. The axial movement is limited by the mating balance between the positioning wheel 46 and the positioning sliding track of the guide rod 10, thereby driving the sleeve component 4 to move up or down.

[0073] Preferably, the bearing 44 is connected to the mating rod 45. When the motor of the drive device 7 drives the main shaft 5 to rotate the sleeve component 4, the mating rod 45 and the positioning wheel 46 can be prevented from rotating together with the sleeve component 4 through the transition of the bearing 44.

[0074] Preferably, the adsorption device 42 is provided with a disc, and the bottom of the disc is provided with an adsorption element 43. The adsorption element 43 is made of soft water-absorbing material. When the adsorption device 42 is in the process of up and down squeezing, it is not easy to damage the clothes 12 when it acts on the clothes 12. After the washing time reaches the set time, it adsorbs stains or sewage and carries them out of the washing area of ​​the inner drum 2.

[0075] The absorbent material is characterized by its ability to absorb a certain amount of water and to expel the water through force or mechanical action. It can be made of water-absorbing cotton or plush fabric, and no specific restrictions are made in this invention.

[0076] More preferably, the guide rod 10 is provided with a sensor 13 for detecting the position signal of the adsorption device 42. Example

[0077] like Figures 5-8 As shown, this embodiment discloses a squeeze adsorption washing control method, using a squeeze adsorption washing device as described in Embodiment 1, including the following steps:

[0078] S101: Receives a start signal and controls the squeezing adsorption washing device to start;

[0079] S102: After the washing device is started, the main wash water intake stage is performed;

[0080] S103: Enter the main wash cycle;

[0081] Step S103 specifically includes:

[0082] S1031: The main wash begins, and water enters from the top of the inner drum through the water inlet pipe;

[0083] S1032: Controls the adsorption device to descend a distance L1 from its initial position;

[0084] S1033: Determine whether the distance L1 and the preset distance Li1 satisfy L1≥Li1. If L1<Li1, go to S1034. If L1≥Li1, go to S1035.

[0085] The preset distance Li1 is the set distance from the initial position of the adsorption device to the clothing; the initial position of the adsorption device is at least 15 cm higher than the upper end of the inner cylinder, so as not to block the water from entering the spraying component of the spraying device.

[0086] In this embodiment, the upward or downward movement is based on the initial position of the adsorption device. For example, when the inner diameter of the inner cylinder 2 is 30 cm and the height of the inner cylinder is 40 cm, it is preferable to use the position where the adsorption device is 15 cm above the upper end of the inner cylinder as the reference position. At this time, the distance between the adsorption device and the bottom of the inner cylinder 2 is 55 cm.

[0087] The preset distance Li1 can be determined based on the inner diameter of the inner tube 2 and the number of clothes. Specifically, it can be selected from 25 to 60 centimeters. For example, when there are 1-2 pieces of clothing, the preset distance Li1 is preferably 50 centimeters; when there are 3-4 pieces of clothing, the preset distance Li1 is preferably 45 centimeters. The preset distance Li1 can be automatically selected according to the actual number of clothes set by the user.

[0088] Alternatively, the clothing detection system can automatically select a preset distance Li1 based on the height of the detected clothing in the inner drum. When there are fewer clothes, the height of the clothes in the inner drum is relatively low, and the adsorption device descends a greater distance L1. Conversely, when there are more clothes, the height of the clothes in the inner drum is relatively high, and the adsorption device descends a lesser distance L1. The clothing detection system can be a photosensitive detection system or a system that reflects light, which are publicly available technologies and will not be described in detail.

[0089] S1034: Continue to control the adsorption device to continue descending until L1≥Li1 is satisfied;

[0090] S1035: Control the adsorption device to press and adsorb up and down within a preset distance range L at a set frequency for a preset time T1, then switch to S1036.

[0091] The preset distance range L is between Li1-L0 and Li1+L0, satisfying the condition L1≥Li1, where the adsorption device exerts pressure on the clothing. The value of L0 can be selected from 0-5 cm, preferably 2 cm. That is, the preset distance range L is between Li1-2 cm and Li1+2 cm.

[0092] The set frequency is the ratio of the lifting time to the squeezing time of the adsorption device, and can be selected as 1 / 1, 1 / 2, 1 / 5, etc., for example, lifting for 1 second and then squeezing for 2 seconds. At the set frequency, the adsorption device will not make large movements, so the time for each squeezing adsorption is shorter, the effective washing time will be increased, which is beneficial to cleaning.

[0093] The preset time T1 can be selected from 0 to 60 seconds, with 20 to 30 seconds being preferred.

[0094] S1036: Control the rising distance L2 of the adsorption device; the preset distance Li2 is the position where the adsorption device returns from the position Li1 to the initial position. At this time, the initial rising position is selected as the position when the adsorption device descends from the initial position to the set distance Li1, that is, after the process of S1035 is completed, the adsorption device is at the position when it descends from the initial position to the set distance Li1.

[0095] S1037: Determine whether the distance L2 and the preset distance Li2 satisfy L2≥Li2; the preset distance Li2 is a set distance above the upper end face of the inner cylinder;

[0096] If L2 < Li2, the adsorption device continues to rise until L2 ≥ Li2 is satisfied; if L2 ≥ Li2, proceed to S1038.

[0097] S1038: Control the adsorption device to stop moving up and down, control the adsorption device to rotate for a preset time T2, and throw the stains and water on the adsorption element 43 into the space between the inner cylinder and the outer cylinder.

[0098] The rotational speed of the adsorption device can be selected from 200-600 rpm, preferably 300-400 rpm. The preset time T2 can be selected from 5-60 seconds, preferably 5-10 seconds.

[0099] Preferably, the preset distance Li2 is equal to Li1, that is, Li2 = Li1, and preferably 50 cm (at which point the water returns to the initial position). This distance setting ensures normal water ejection without blocking the water inlet of the nozzle.

[0100] S1039: After shaking off the stains and water on the adsorption component 43, control the adsorption device to descend a distance L3; the preset distance Li3 is the set distance from the reference position to the Li3 position of the adsorption device.

[0101] S10310: Perform a logical judgment on whether the distance L3 and the preset distance Li3 satisfy L3≥Li3; if L3<Li3, go to S10311; if L3≥Li3, go to S10312.

[0102] When the descent distance L3 is greater than or equal to the preset distance Li3, the upper surface of the adsorption device is lower than the upper surface of the inner cylinder to prevent water from splashing out.

[0103] Preferably, the preset distance Li3 is 3 / 8 to 5 / 8 of the height of the inner cylinder. For example, if the height of the inner cylinder is 40 cm, Li3 is 15-25 cm, preferably 20 cm.

[0104] S10311: Control the adsorption device to continue descending until L3≥Li3 is satisfied;

[0105] S10312: Control the adsorption device to stop moving for a preset time T3, then proceed to S10313;

[0106] S10313: Detect the water level in the inner cylinder and determine whether the current water level W and the low water level W1 satisfy W≥W1. If W<W1, proceed to S10314; if W≥W1, proceed to S10315.

[0107] The water level can be detected by a water level sensor or by setting a high / low level control switch, which is existing technology. The low water level value W1 is the lowest water level to prevent the circulating pump from evacuating. It can be selected as a position 10-15 cm above the bottom of the inner cylinder, preferably 10 cm.

[0108] For example, when the inner diameter of the inner cylinder is 30 cm, the corresponding water volume is about 7 L; the water level value W2 is higher than the low water level value W1, and W2 can be 5-10 cm higher than W1, that is, when the inner diameter of the inner cylinder is 30 cm, the corresponding water volume increases by about 4-7 L.

[0109] S10314: Open the water inlet valve, and replenish water into the cylinder through the water outlet of the water inlet pipe of the spray device until the water level reaches W2. Then, perform water level detection and judgment again until W≥W1 is satisfied.

[0110] The water replenishment in step S10314 is to prevent the water level from being too low, which would cause the circulating pump to produce dry suction, and also to prevent the water volume from being too low, which would increase the friction between the clothes and the bottom of the drum.

[0111] S10315: Turn on the circulation pump to spray water onto the clothes from the spray hole at the bottom of the inner drum for a preset time T4, so that the clothes are turned over.

[0112] The spray nozzles are angled, which agitates the clothes. This prevents the clothes from remaining still, as prolonged pressure from the disc of the adsorption device can lead to uneven washing or localized damage to the clothes. Furthermore, the spray force helps stains on the clothes enter the washing water.

[0113] S10316: After the spraying and agitation in step S10315, a squeezing and washing cycle is performed to determine whether the cycle number n and the preset value K satisfy n≥K. If n≥K, the main washing process ends and the main washing and draining process S104 is executed. If n<K, steps S1032~S10316 are executed again. Each execution increments the corresponding cycle number n by 1 until n≥K is satisfied, at which point the cycle ends.

[0114] The preset value K can be selected from 4 to 120, preferably 20 to 40. The times T3 and T4 satisfy: T3 ≥ T4, preferably T3 = T4, and the time T3 can be selected from 2 to 30 seconds, preferably 3 to 5 seconds.

[0115] S104: After the main wash cycle is completed, the main wash drainage stage is performed;

[0116] Preferably, the main wash and spin-drying process is not performed, which simplifies the overall washing process and reduces the total time consumption.

[0117] S105: Spray rinsing;
