Description

[0002] With the upgrading of consumption and the improvement of user's life quality, more and more household appliances are needed in a family. A washing machine is an indispensable household appliance in a contemporary family, and a drum washing machine is more and more popular in families. Generally, the position of a door body assembly of the drum washing machine is relatively low, so the user needs to bend down to take out clothes from an inner drum after washing. However, the inner drum of the current drum washing machine is relatively deep, and after washing, many clothes often accumulate in the deep inner drum. In this case, the clothes cannot be easily reached by hand due to the too deep inner drum, so the user needs to bend down more to take out the clothes, which results in that it is very laborious to take out the clothes. In order to improve this situation, some drum washing machines are designed to be relatively narrow and not so deep. This method indeed can improve the problem of laborious taking out of clothes, but this method results in that the overall capacity of the washing machine is small, and the washing performance is also affected.

DETAILED DESCRIPTION

[0054] In the description of the present application, it should be noted that the positions or location relationships indicated by the terms "inner", "outer" and the like are based on the positions or location relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0055] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "contact", "communication" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0056] To solve the problem that it is difficult to take clothes due to the deep inner cylinder of the existing drum washing machine. The first aspect of the embodiment provides a clothes processing equipment, which combines Figure 1 The clothes processing equipment includes an inner cylinder 2 and an outer cylinder 3, and further includes:

[0057] A metal piece 4 is fixed to the outer wall of the inner cylinder 2 on the side away from the cylinder opening;

[0058] An electromagnet 5 is fixed to the inner wall of the outer cylinder 3;

[0059] When the position of the inner cylinder corresponds to the position of the metal piece 4, the electromagnet 5 generates an electromagnetic force on the metal piece 4 under the action of current, and the electromagnetic force makes the metal piece 4 drive the inner cylinder to produce eccentric motion.

[0060] The embodiment can artificially introduce an eccentricity at the rear end of the inner drum by electromagnetic force. By introducing an additional eccentricity, a force with a certain angle with the horizontal central axis exists, so that the clothes close to the inner drum wall can be loosened or part of the clothes load is moved to the front end of the inner drum first. According to the principle of compensating eccentricity, the front end of the inner drum must have a certain weight load to compensate for the eccentricity at the rear end of the inner drum to achieve an eccentricity balance effect, so that the load deep in the inner drum will move from the rear end of the inner drum to the front end of the inner drum under the action of the compensating eccentricity. This method is beneficial to peeling off the clothes load close to the wall, and prepares for moving all the clothes to the front end of the inner drum in the shaking stage, effectively improving the problem of laborious clothes taking caused by the over-deep inner drum.

[0061] Further optionally, the clothes treatment apparatus further comprises:

[0062] a detection device arranged on the inner drum wall, the detection device being configured to monitor a distribution state of the clothes load in the drum;

[0063] Optionally, a plurality of contact-type pressure sensors are arranged on the inner drum wall of the drum washing machine. The distribution state of the load on the inner drum wall is monitored by the plurality of contact-type pressure sensors in the last dehydration stage and the last shaking stage of washing, so as to determine the amount of load in the middle or rear end of the inner drum, and to prepare for the subsequent artificial introduction of eccentric force.

[0064] Optionally, a camera device is arranged in the inner drum of the drum washing machine, and the camera device is used to obtain the distribution state of the clothes in the drum.

[0065] Preferably, the detection device comprises a plurality of pressure sensors 1, which are uniformly distributed on the inner wall of the inner drum 2.

[0066] Specifically, the sensors 1 are distributed on the front end, the middle and the rear end of the inner drum, and can determine the distribution state of the load in the entire inner drum according to the pressure caused by the clothes load. The clothes treatment apparatus controls the electromagnetic force of the electromagnet 5 according to the distribution state of the load, so as to achieve a suitable eccentric force.

[0067] Further optionally, the electromagnet 5 is connected to a power supply, and the current of the electromagnet 5 can be controlled to generate different electromagnetic forces according to the distribution state of the clothes load in the drum, and the metal part 4 is attracted by different electromagnetic forces, so that the inner drum generates different eccentricities.

[0068] Specifically, different electromagnetic forces are generated in the electromagnet 5 by different current sizes, so as to generate different attractive forces on the metal part (preferably a metal ring) installed at the rear end of the inner drum, so as to achieve different eccentric values.

[0069] Preferably, the metal part 4 is a metal ring, which is sleeved on the outer wall of the inner cylinder 2; the electromagnet 5 is fixed at a position corresponding to the upper half of the outer cylinder 3 and the inner cylinder 2. Further optionally, there is one electromagnet 5, which is set at a position on the inner circumferential wall of the outer cylinder corresponding to the central axis of the inner cylinder, so that the load of clothes at the rear end of the inner cylinder can move from the rear end of the inner cylinder to the front end of the inner cylinder under the action of eccentric motion;

[0070] Alternatively, two electromagnets 5 can be symmetrically arranged on the upper inner circumference of the outer drum relative to the center face of the inner drum, so that the load of clothes at the rear end of the drum can move from the rear end of the inner drum to the front end of the inner drum under the action of eccentric motion.

[0071] Further optionally, multiple sets of electromagnets 5 are arranged circumferentially along the inner wall of the outer cylinder, each set having two electromagnets symmetrically distributed relative to the center of the cylinder, and at least one set can cause the inner cylinder to generate eccentric movement in the Y direction, so that the load of clothes at the rear end of the cylinder can move from the rear end of the inner cylinder to the front end of the inner cylinder under the action of eccentric movement.

[0072] Specifically, the central axis of the inner drum is taken as the X-axis, the direction perpendicular to the X-axis and vertically upward is taken as the Y-axis, and the direction perpendicular to the X-axis and horizontal is taken as the Z-axis. That is, during the washing and spin-drying process, an electromagnet positioned directly above the central axis of the inner wall of the outer drum is energized, generating an electromagnetic force. This electromagnetic force acts on a metal ring, attracting the ring and causing an eccentricity at the rear end of the inner drum. This eccentric movement allows the load of clothes at the rear end of the inner drum to move from the rear end to the front end.

[0073] It should be noted that when multiple sets of electromagnets are spaced apart along the inner circumference of the outer drum, with each set containing two electromagnets symmetrically distributed relative to the center of the drum, these sets of electromagnets can cause the inner drum to produce eccentric motion in the Y-direction, as well as eccentric motion in the left-right direction (Z-axis). They can also cause eccentric motion at the rear end of the inner drum in other directions between the Y and Z directions. This directional effect facilitates the shedding of clothing clinging to the drum walls, preparing for the shaking and loosening stage. It effectively improves the problem of difficulty in retrieving clothing caused by an excessively deep inner drum without changing the size and capacity of the inner drum, while also effectively loosening the clothing.

[0074] Specifically, the metal part is a metal part easily attracted by magnetic force, and its material can be iron, cobalt, nickel, etc. Optionally, a metal ring easily attracted by magnetic force is added to the rear end of the outer wall of the inner drum of the drum washing machine. The metal ring is very light and will not affect the normal operation of the washing machine. At the same time, an electromagnet device is added to the inner wall of the outer drum directly above the metal ring. By generating different current magnitudes based on the load distribution of clothes determined by the pressure sensor, different electromagnetic forces are generated, which in turn exert different attraction forces on the ring at the rear end of the inner drum. The two do not stick together and have a certain gap between them, thus achieving different eccentric values. In the final spin-drying stage, this eccentricity is introduced at the rear end of the inner drum using electromagnetic force. According to the principle of compensating for eccentricity, the front end of the inner drum must have a certain weight load to compensate for the eccentricity at the rear end of the inner drum, so as to achieve an eccentric balance effect. Therefore, the load at the rear end of the inner drum will move from the rear end to the front end of the inner drum under the force of compensating for eccentricity.

[0075] The second aspect of this embodiment provides a control method for the garment processing equipment of any of the first aspects, combined with Figure 3 The control method includes step S1:

[0076] S1, during the final spin-drying and / or shaking stage of the washing machine, controls the current supplied to the electromagnet to generate different electromagnetic forces according to the distribution of the clothes load inside the drum. Under the attraction of different electromagnetic forces, the metal parts cause the inner drum to produce different degrees of eccentricity.

[0077] This embodiment introduces an eccentricity at the rear end of the inner drum using electromagnetic force. This additional eccentricity creates a force at a certain angle to the horizontal central axis, allowing clothing tightly adhering to the inner drum wall to loosen or partially loosen and move to the front end of the inner drum. Simultaneously, based on the principle of eccentricity compensation, the front end of the inner drum must have a certain weight load to compensate for the eccentricity at the rear end, achieving an eccentric balance. Therefore, under the force of the eccentricity compensation, the load deep within the inner drum will move from the rear end to the front end. This method facilitates the shedding of clothing adhering to the wall, preparing for the shaking stage to move all clothing to the front end of the inner drum, effectively improving the problem of difficulty in retrieving clothing due to an excessively deep inner drum.

[0078] Alternatively, based on the metal part being a metal ring, the electromagnet is disposed on the inner wall of the outer cylinder, and located directly above the central axis of the outer cylinder, corresponding to the position of the metal ring, in combination with... Figure 3 The control method further includes S2:

[0079] S2 utilizes the eccentric motion of the inner drum combined with the rotation of the inner drum to allow the load of clothing at the rear end of the inner drum to move from the rear end to the front end of the inner drum under the action of the eccentric motion.

[0080] Specifically, when the metal part is a metal ring, the metal ring is fitted on the outer wall of the rear end of the inner drum, and the electromagnet is set on the inner wall of the outer drum, and is located directly above the central axis of the outer drum and corresponding to the metal ring. In the final dehydration braking stage and the final shaking stage, an eccentricity is artificially introduced at the rear end of the inner drum using electromagnetic force. According to the principle of compensating for eccentricity, the front end of the inner drum must have a certain weight load to compensate for the eccentricity at the rear end of the inner drum, so as to achieve an eccentric balance effect. Therefore, the load deep inside the inner drum will move from the rear end of the inner drum to the front end of the inner drum under the force of compensating for eccentricity. This method effectively improves the problem of difficulty in taking out clothes caused by the inner drum being too deep.

[0081] Further, optionally, combined Figure 4 The final dehydration stage includes a braking and deceleration stage and a shaking and dispersing stage. S2 includes:

[0082] S21, during the braking and deceleration phase, controls the dehydration motor to drop from the preset speed to zero speed, and uses the eccentricity generated by electromagnetic force to loosen the load or partially drop it to the front end of the inner cylinder.

[0083] S22, during the shaking stage, controls the forward and reverse rotation of the spin-drying motor to shake the clothes, and uses the eccentricity generated by electromagnetic force to move all the clothes to the front of the inner drum.

[0084] Specifically, this electromagnet-induced eccentricity device only operates during the final dehydration braking and deceleration stage and the final shaking stage. It does not operate in other stages and does not affect the operation of other stages. First, in the first stage, the final dehydration braking and deceleration stage, which is the last stage before shaking, the electromagnet device introduces eccentricity during the time interval between V1 and 0 rpm, with V1 not exceeding 110 rpm. During the braking and deceleration process, the introduced eccentricity creates a force at a certain angle to the horizontal axis, allowing clothes that are tightly attached to the inner drum wall to loosen or partially fall to the front of the inner drum, preparing for the shaking stage to move all the clothes to the front of the inner drum. The second stage is the final shaking stage. During the shaking stage, the inner drum rotates alternately in both directions to shake or scatter the clothes. Again, the introduced eccentricity allows clothes that were still located at the rear or middle of the inner drum after the braking and deceleration stage to be completely moved to the front of the inner drum under the compensating force of the eccentricity. Furthermore, during the final dehydration braking and speed-down stages and the final shaking stage, the load distribution within the inner drum is determined based on the pressure sensor readings. If most of the load is at the rear of the inner drum, a larger eccentricity is required, meaning a larger electromagnetic force is needed. Conversely, if most of the load is in the middle of the inner drum or only a small portion is at the rear, a smaller eccentricity is sufficient, requiring less electromagnetic force. Additionally, the load on the inner drum is more tightly packed against the drum wall in the first stage compared to the second, resulting in greater stress. Therefore, the electromagnetic force in the first stage is generally greater than that in the second stage. In these two stages, the magnitude of the electromagnetic force is selected based on the load distribution determined by the pressure sensor, creating different eccentricities so that the clothes can move to the front of the inner drum after the final dehydration braking and speed-down stages and after shaking, making them easy to retrieve.

[0085] Further, optionally, combined Figure 5 During the braking and deceleration phase, step S1 controls the electromagnet to generate different electromagnetic forces based on the distribution of the clothing load within the drum, including S11 to S13, wherein:

[0086] S11, determine if most of the load is at the rear end of the inner cylinder; if yes, execute S12; if no, execute S13.

[0087] S12 controls the electromagnet to generate the first electromagnetic force F1;

[0088] S13 controls the electromagnet to generate a second electromagnetic force F2;

[0089] Among them, F1 > F2.

[0090] Specifically, in the first stage, two electromagnetic forces, F1 and F2, are set according to the distribution of the load in the inner cylinder. F1 is used for the rear end of the inner cylinder with a large load, and F2 is used for the rear end of the inner cylinder with a small load. F1 > F2.

[0091] Further, optionally, combined Figure 5 During the shaking stage, the electromagnet is controlled to generate different electromagnetic forces according to the distribution of the clothing load inside the drum, including the following steps:

[0092] A1, determine if most of the load is at the rear of the inner cylinder; if yes, execute A2; if no, execute A3.

[0093] A2 controls the electromagnet to generate a third electromagnetic force F3;

[0094] A3 controls the electromagnet to generate the fourth electromagnetic force F4;

[0095] Among them, F2 > F3 > F4.

[0096] Further optionally, during the shaking stage, the control method further includes steps A4 to A5, wherein:

[0097] A4. Determine if the entire load is at the front end of the inner cylinder; if yes, proceed to A5; if no, repeat steps A1 to A3.

[0098] A5, dehydration complete.

[0099] Specifically, in the second stage, two electromagnetic forces, F3 and F4, are set according to the distribution of the load in the inner drum. F3 is used for a heavier load at the rear of the inner drum, and F4 is used for a lighter load at the rear of the inner drum. F3 > F4, and the overall order is F1 > F2 > F3 > F4. At the end, the pressure sensor determines whether all the clothing load has moved to the front of the inner drum. If so, the entire process ends and the machine is turned off. If there are still some clothes remaining at the rear and middle of the inner drum, the shaking process is repeated until all the clothes have moved to the front of the inner drum. At this point, the entire process ends and the machine is turned off.

[0100] Further optionally, the control method further includes monitoring the distribution of the clothing load within the drum, wherein monitoring the distribution of the clothing load within the drum includes S01 to S02, wherein:

[0101] S01, monitors the pressure of the clothing load on various areas of the inner wall of the inner drum;

[0102] S02, compare the pressure of the clothes load on different areas of the inner wall of the inner drum to determine whether most of the load is at the rear end of the inner drum or whether all the load is at the front end of the inner drum.

[0103] This device utilizes the principle of eccentric compensation. The principle is that when an object moves in a circle, a force is applied at one end. To balance this force, a corresponding force must also be applied at the opposite diagonal position to cancel it out, achieving eccentric balance. In this embodiment, an eccentric force is applied to the rear end of the inner drum. To balance this force, the load of clothes in the inner drum needs to move to the front end, creating a centrifugal force that cancels out the eccentric force at the rear end, achieving balance. A lightweight metal ring, easily attracted by magnetism, is added to the rear end of the inner drum of the washing machine, ensuring it does not affect the normal operation of the machine. Simultaneously, an electromagnet is installed on the inner wall of the outer drum directly above the metal ring. This electromagnet generates different currents based on the load distribution of the clothing as determined by the pressure sensor, thus producing different electromagnetic forces. These forces exert varying attraction on the ring at the rear of the inner drum, preventing them from adhering together and maintaining a certain gap. This achieves different eccentricity values. During the final spin-drying and shaking stages, this eccentricity is artificially introduced at the rear of the inner drum using electromagnetic force. According to the principle of eccentricity compensation, the front of the inner drum must have a certain weight load to compensate for the eccentricity at the rear, achieving a balance. Therefore, the load at the rear of the inner drum moves from the rear to the front under the force of eccentricity compensation. Furthermore, due to the additional electromagnetic force, a force is generated at an angle to the central axis of the inner drum. This helps to peel off the load of clothing adhering to the inner drum wall, further enhancing the beneficial effect described in this paper—that is, the movement of clothing 6 to clothing 7 in the diagram.

[0104] A third aspect of the present invention provides a control device for a garment processing apparatus, comprising one or more processors and a non-transitory computer-readable storage medium storing program instructions, wherein when the one or more processors execute the program instructions, the one or more processors are configured to implement the control method according to any one of the second aspects.
