[0048] In this embodiment, a method for controlling a washing machine is provided. Figure 2 FIG. 1 is a flow chart of a method for controlling a washing machine according to an embodiment of the present invention. Figure 2 As shown, the process includes the following steps:
[0049] Step S202: Detecting the spatial position of a target washing compartment in a washing machine, wherein the washing machine includes an inner drum and a plurality of washing compartments assembled inside the inner drum, wherein the inner drum is connected to each washing compartment via an openable and closable isolation door;
[0050] The washing machine of this embodiment is a washing machine with a separate washing function. The washing machine includes multiple washing compartments including an inner drum. In addition to the inner drum (which can be the main washing compartment), it also includes several separate washing compartments assembled inside the inner drum, forming a drum-in-drum structure. Figure 3 1 is a structural diagram of the inner drum of a washing machine according to an embodiment of the present invention, illustrating the following structures: inner drum 1; drain outlet 2; separate washing compartment 3 and separate washing compartment door 4 (isolation compartment door). Figure 4 This is the structure of the washing machine washing compartment in the embodiment of the present invention Figure 1The diagram illustrates the following structure: inner drum 1, separate wash compartment 3, separate wash compartment door 4 (isolation compartment door), water inlet 5, and door switch 6. Separate wash compartment 3 is one of the separate wash compartments shown, connected to the inner drum via the isolation compartment door. The door switch controls the opening and closing of the isolation compartment door. This embodiment uses the inner drum as an example, with three separate wash compartments evenly spaced at 120° intervals. The washing machine includes four wash compartments: the inner drum and separate wash compartments 1, 2, and 3.
[0051] Step S204: controlling the washing state of the target washing compartment according to the spatial position.
[0052] Optionally, according to the washing mode set by the user, the washing state can be one or more of the water filling state, drainage state, dehydration state, drying state, etc.
[0053] Through the above steps, the spatial position of the target washing compartment in the washing machine is detected, wherein the washing machine includes an inner drum and several washing compartments assembled inside the inner drum, the inner drum is connected to each washing compartment through an openable and closable isolation compartment door, and the washing state of the target washing compartment is controlled according to the spatial position. By assembling the washing compartment in the inner drum, the effect of washing clothes separately is achieved, which can effectively avoid cross-infection of bacteria. By controlling the washing state of each washing compartment by spatial position, orderly automatic washing of the inner drum and the washing compartment inside the inner drum is achieved, which solves the technical problem of low efficiency of washing clothes in washing machines in related technologies, and achieves the effect of energy saving, convenience and effective prevention of cross-infection of bacteria.
[0054] In one implementation of this embodiment, detecting the spatial position of the target washing compartment in the washing machine includes:
[0055] S11, controlling the target separation tank to rotate one circle in the polar coordinate system at a preset speed from the initial position;
[0056] Optionally, this embodiment uses the inner cylinder center and inner cylinder radius (corresponding to the ray from the inner cylinder center to the target separation tank) to create a polar coordinate system. Before controlling the target separation tank to rotate one revolution in the polar coordinate system from an initial position at a preset rotation speed, the method further includes: determining the first center coordinate of the inner cylinder and the second center coordinate of the target separation tank in the world coordinate system; creating a polar coordinate system with the first center coordinate as the pole and the line connecting the first and second center coordinates as the polar axis; and configuring the coordinates of the initial position of the target separation tank in the polar coordinate system as (R, 0), where R is the length of the line connecting the first and second center coordinates.
[0057] By creating a polar coordinate system, the real-time polar coordinates of the target washing tank are (R, θ), where θ represents the counterclockwise angle from Ox to the polar axis, O is the pole, and x is the current position of the target washing tank in the world coordinate system.
[0058] By rotating one circle, the target washing compartment can be returned to its initial position without changing its initial position so as to facilitate subsequent adjustments, and at the same time complete the detection of its spatial position.
[0059] S12, detecting the rotation time of the target washing compartment from the initial position to the calibration position;
[0060] Optionally, the calibration position may be a pre-set reference position such as the top of the inner cylinder or the bottom of the inner cylinder.
[0061] S13, calculating the rotation angle of the target separation tank from the initial position to the calibration position using the rotation time and the preset rotation speed;
[0062] Among them, the rotation angle depends on the rotation direction. If it rotates clockwise, the rotation angle is the clockwise angle of the target separation tank from the initial position to the calibrated position. If it rotates counterclockwise, the rotation angle is the counterclockwise angle of the target separation tank from the initial position to the calibrated position. The clockwise angle and the counterclockwise angle can be converted to each other.
[0063] S14, determining the rotation angle as the spatial position of the target washing compartment at the initial position.
[0064] In an example of this embodiment, after detecting the spatial position of the target washing compartment in the washing machine, it also includes: determining whether the spatial position of the target washing compartment is at the target position of the inner drum; if the spatial position of the target washing compartment is not at the target position of the inner drum, controlling the inner drum to rotate in a preset direction until the target washing compartment is at the target position.
[0065] In one example, the position of the separation tank can be detected by measuring the counterclockwise angle θ1 = W * T1 between the target separation tank and the calibration position, where W is the clockwise angular velocity and T1 is the rotation time from the calibration position to the initial position. The inner drum can then be controlled to rotate counterclockwise by θ1. This counterclockwise rotation can prevent the controller from misjudging whether water filling is complete. Alternatively, the inner drum can continue to rotate clockwise by 360° - θ1.
[0066] In one example, the top of the inner barrel is used as the calibration position, and an infrared transceiver (infrared transmitter and receiver) is set on the top of the inner barrel. The rotation time is calculated by the emission time and reflection time of the infrared ray. First, the center of the inner barrel is used as the center of the polar coordinate axis, and the line connecting the center of the inner barrel and the center of the target washing tank is used as the polar axis to locate the initial position of the target washing tank (R, 0), where R is the radius of the inner barrel. In the process of detecting the position of each washing tank, the controller controls the infrared transmitter and receiver to turn on, and the motor rotates one circle at a speed W. When the target washing tank rotates from the initial position to the top, the water inlet The reflective sheet on the door 10 of the target separation cabin reflects the infrared rays back, and the time T0 for the target separation cabin to move from the initial position to the top and the time T1 for the target separation cabin to move from the top to the initial position are recorded. Then, the clockwise angle θ0 = W*T0 and the counterclockwise angle θ1 = W*T1 formed by the initial position of the target separation cabin and the ideal position can be determined, thereby determining the initial position of the target separation cabin. If there are other separation cabins, they are arranged in a predetermined interval pattern with the target separation cabin in the inner cylinder, and the initial positions of the other separation cabins can also be determined by calculating the fixed angles between the two separation cabins.
[0067] In this embodiment, according to the program setting of the washing mode, the washing machine needs to execute multiple washing processes in sequence, and the inner drum and the washing compartment will enter multiple washing states in sequence, such as the water filling stage, the drainage stage, the dehydration stage, etc.
[0068] In an implementation scenario of this embodiment, during the water filling stage, controlling the washing state of the target washing tank according to the spatial position includes: determining whether the spatial position of the target washing tank is at the top of the inner drum; if the spatial position of the target washing tank is at the top of the inner drum, controlling the target washing tank to enter the water filling state, and opening the water inlet of the target washing tank until the water level of the target washing tank reaches the set value, wherein the target washing tank is equipped with a separate water inlet.
[0069] Figure 5This is a control flow chart for filling a washing machine with water according to an embodiment of the present invention. The inner drum includes three separate wash compartments, namely, compartments 1, 2, and 3, evenly spaced at 120° intervals. The water inlets of the three separate wash compartments are located at the very top of the inner drum. When a separate wash compartment is at the very top of the inner drum, an electromagnetic rod controls the opening and closing of the water inlet door, allowing water to flow in. Therefore, water can only be filled when the target separate wash compartment is spatially located at the top of the inner drum. When filling water, the inner drum and the separate washing compartment are filled with water at the same time. When filling separate washing compartments 1, 2, and 3 with water, the position of each separate washing compartment must be detected first. When one of the separate washing compartments is located at the top of the inner drum (ideal position), the controller controls the electromagnetic rod on the top of the water inlet to be energized, so that it has a magnetism different from that of the magnet on the water inlet door. The door of the water inlet is opened by the principle of magnetism, and the separate washing compartment at the top of the inner drum begins to be filled with water. The gravity sensor inside the separate washing compartment is used to determine whether the total weight of the water and the weight of the clothes reaches the set value. When the set value is reached, the controller controls the electromagnetic rod to be de-energized, the water inlet door is closed, the water filling is completed, and the separate washing compartment is switched to fill with water. If, at this time, the inner barrel only needs to rotate 120° clockwise to achieve the purpose of changing the area of water supply, and the controller records the number of times the inner barrel rotates 120°, and judges whether the water filling of all the sub-wash tanks is completed by the number of times the inner barrel rotates 120° clockwise, that is, if the number of times the inner barrel rotates 120° clockwise is greater than 2, the water filling of all the sub-wash tanks has been completed.
[0070] If the washing compartments are not in the ideal position, that is, there is no washing compartment at the top of the inner drum initially, the controller controls the inner drum to rotate counterclockwise to place the washing compartment in the ideal position. After the water filling is completed, the washing compartment and the inner drum operate simultaneously for washing. Taking the washing compartment 1 as an example, the counterclockwise angle θ1=W*T1 (W is the motor speed, and in the position detection stage of the washing compartment, the time for the washing area 1 to move from the top to the initial position is T1) formed by the washing compartment 1 and the ideal position can be detected by detecting the position of each washing compartment. At this time, the counterclockwise angle formed by other washing compartments and the ideal position can also be determined, so that the motor can be controlled to select the corresponding angle to return it to the ideal position. For example, if the motor is controlled to rotate counterclockwise and the washing compartment 1 is adjusted to the ideal position, it can prevent the main controller from making a wrong judgment when judging whether the water filling is completed.
[0071] In this implementation scenario, during the water filling stage, water is added to the separate washing compartments by judging their positions, and whether all the separate washing compartments have been filled with water is checked by rotating the inner drum 120° clockwise. The water filling amount is adjusted by detecting the weight of each separate washing compartment, thereby achieving separate water filling for each separate washing compartment and preventing the washing machine from hitting the drum due to unstable center of gravity during operation.
[0072] In an implementation scenario of this embodiment, during the drainage stage, controlling the washing status of the target washing compartment according to the spatial position includes: determining whether the spatial position of the target washing compartment is at the bottom of the inner drum; if the spatial position of the target washing compartment is at the bottom of the inner drum, controlling the target washing compartment to enter the drainage state, and opening the drain port of the target washing compartment until the drainage of the target washing compartment is completed, wherein the target washing compartment is equipped with a separate drain port.
[0073] By draining the wash tank at the bottom of the inner drum, the drain port can be located at the bottom of the wash tank when the wash tank rotates to the bottom of the inner tub. This allows the wash tank to drain faster due to gravity and effectively prevents wash water from flowing into the inner tub when the wash tank is draining. If the wash tank is drained at other locations, wash water may flow down the back wall of the inner tub and then into the inner tub, causing cross-contamination.
[0074] Figure 6 This is a control flow chart for draining water from a washing machine according to an embodiment of the present invention. The water is drained before dehydration. To prevent the wash water in the separate wash compartments from mixing with the wash water in the inner tub and causing cross contamination, drainage from each area is performed sequentially. First, the controller opens the drain valve in the inner tub, draining the inner tub first. When the water level sensor detects that the water in the inner and outer tubs has separated, meaning the water level in the outer tub is lower than that in the inner tub, the separate wash compartments are drained. To prevent cross-infection, each separate compartment is drained at a specific point. This involves first checking the position of each compartment. If a compartment is at the very bottom of the inner drum, the controller controls the electromagnetic rods on the outer drum (on either side of the drain outlet) to conduct electricity, causing the left electromagnetic rod to have the same magnetic field as the magnet on the drain door, while the right electromagnetic rod has the opposite magnetic field. This magnetic force opens the drain door, allowing the water to drain. A gravity sensor inside the separate compartment determines whether the water has been drained. Once the water has been drained, the drainage area is switched. The controller then controls the inner drum to rotate 120° clockwise, placing another separate compartment in the ideal position for drainage. The controller also records the number of 120° clockwise rotations, and uses this number to determine whether all separate compartments have been drained. If the inner drum has rotated 120° clockwise more than twice, all separate compartments are drained.
[0075] If the washing tank is not in the ideal position for drainage at the beginning, the position is adjusted by rotating the inner drum counterclockwise. The polar coordinates of each washing tank can be obtained by detecting the position of each washing tank, so that the clockwise and counterclockwise angles formed by the initial position of each washing tank and the top of the inner drum can be determined. Taking washing tank 1 as an example, the counterclockwise angle θ1 = W*T1 formed by washing tank 1 and the ideal position (such as the bottom of the inner drum) can be detected by detecting the position of each washing tank (W is the motor speed, and the time it takes for washing zone 1 to move from the top to the initial position during the position detection phase is T1). Then, the clockwise angle formed by the initial position of the washing tank and the bottom of the inner drum can be obtained by adding it to the clockwise angle, so that the motor can be controlled to return it to the bottom (ideal position).
[0076] In this implementation scenario, during the drainage phase, the drain outlets of each washing compartment are opened based on the results of the outer barrel water level detection to prevent the washing water in the inner barrel and the washing water in the divided washing compartments from mixing and causing bacterial cross-infection.
[0077] In an implementation scenario of this embodiment, during the dehydration stage, controlling the laundry status of the target washing compartment according to the spatial position includes: controlling the inner drum and all the washing compartments to dehydrate; after the dehydration is completed, determining whether the spatial position of the target washing compartment is at the top of the inner drum; if the spatial position of the target washing compartment is at the top of the inner drum, controlling the target washing compartment to stay at the top of the inner drum for a preset time; after the preset time, opening the isolation door between the target washing compartment and the inner drum to allow the clothes in the target washing compartment to be mixed into the inner drum.
[0078] Figure 7This is a control flow chart for the dehydration of a washing machine according to an embodiment of the present invention. First, it determines whether the speed-up conditions are met. If so, the dehydration process begins. When the dehydration time reaches the set value, dehydration is considered complete. During the dehydration phase, the drain outlets of each washing compartment are always open. After dehydration is complete, the position of each washing compartment needs to be rechecked. If a washing compartment is located at the very top of the inner tub (the ideal position for mixing clothes), the compartment will pause for 30 seconds to allow the remaining water in the compartment to drain. The controller then controls the electromagnetic rod that opens the washing compartment door to conduct electricity. Using the principle of magnetism, the door switch is pressed, the door opens, and the clothes fall from the washing compartment back into the inner tub using the principle of gravity. The inner tub's gravity sensor detects whether the clothes have completely fallen out. If they have, the controller controls the electromagnetic rod to energize again, and using the principle of magnetism, the door switch is pressed again, closing the washing compartment door. If the clothes have not completely fallen out, the controller controls the inner tub to rotate one circle clockwise, using the principles of inertia and gravity to force the clothes out. After the clothes at the top have completely fallen out, the controller controls the inner tub to rotate 120° clockwise, and the clothes in the other washing compartment are also dropped into the inner tub. The controller determines whether the clothes in all washing compartments have been dropped out by counting the number of times the inner tub rotates 120° clockwise. That is, if the number of times the inner tub rotates 120° clockwise is greater than 2, the clothes in each washing compartment have completely fallen out, the separate washing is completed, and mixed washing is performed in the inner tub.
[0079] If there is no washing compartment at the top of the inner barrel at the beginning, the inner barrel is rotated counterclockwise to adjust the position so that it is in the ideal position. The polar coordinates of each washing compartment can be obtained by detecting the position of each washing compartment. Taking washing compartment 1 as an example, the counterclockwise angle θ1=W*T1 (W is the motor speed, and the time it takes for washing area 1 to move from the top to the initial position during the position detection phase is T1) formed by the washing compartment 1 and the ideal position (such as the top of the inner barrel) can be detected by detecting the position of each washing compartment. In this way, the counterclockwise angle formed by the initial position of each washing compartment and the top of the inner barrel can be determined, and the motor can be controlled to rotate by the corresponding angle to return it to the top (ideal position).
[0080] This implementation scenario can be that at the end of the separate washing stage and before the start of the mixed washing stage, the position of the separate washing compartment is judged to ensure that all the residual water inside the separate washing compartment is drained, and the principle of inertia is used through rotation to ensure that all the clothes in the separate washing compartment fall into the inner drum. The number of times the inner drum rotates 120° clockwise is used to judge whether the residual water in each separate washing compartment is drained and the clothes fall into the inner drum.
[0081] Using the solution of this embodiment, a control method for washing clothes in a drum-in-drum structure has been developed. This control method can achieve fully automatic washing, effectively solving the cumbersome and time-consuming problem of traditional laundry washing, greatly improving washing efficiency, and effectively heating and washing each type of laundry in the separate washing compartments separately. After washing, the laundry in each separate washing compartment falls back into the inner drum, allowing users to access the laundry by simply opening a door, thereby achieving energy conservation, convenience, and effective prevention of cross-infection of bacteria.
[0082] Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus the necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present invention is essentially or the part that contributes to the prior art can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present invention.

[0090] Optionally, during the water filling stage, the control module includes: a first judgment unit, used to judge whether the spatial position of the target separation tank is at the top of the inner tube; a first control unit, used to control the target separation tank to enter the water filling state if the spatial position of the target separation tank is at the top of the inner tube, and open the water inlet of the target separation tank until the water level of the target separation tank reaches a set value, wherein the target separation tank is equipped with a separate water inlet.
[0091] Optionally, in the drainage stage, the control module includes: a second judgment unit, used to judge whether the spatial position of the target separation tank is at the bottom of the inner tube; a second control unit, used to control the target separation tank to enter the drainage state if the spatial position of the target separation tank is at the bottom of the inner tube, and open the drain port of the target separation tank until the drainage of the target separation tank is completed, wherein the target separation tank is equipped with a separate drain port.
[0092] Optionally, during the dehydration stage, the control module includes: a third control unit for controlling the inner drum and all the separate washing compartments to dehydrate; a third judgment unit for judging whether the spatial position of the target separate washing compartment is at the top of the inner drum after the dehydration is completed; a fourth control unit for controlling the target separate washing compartment to stay at the top of the inner drum for a preset period of time if the spatial position of the target separate washing compartment is at the top of the inner drum; and a fifth control unit for opening the isolation door between the target separate washing compartment and the inner drum after the preset period of time has expired, so that the clothes in the target separate washing compartment are mixed into the inner drum.
[0093] Optionally, the device also includes: a judgment module, which is used to judge whether the spatial position of the target washing compartment in the washing machine is at the target position of the inner drum after the detection module detects the spatial position of the target washing compartment in the washing machine; and an adjustment module, which is used to control the inner drum to rotate in a preset direction until the target washing compartment is located at the target position if the spatial position of the target washing compartment is not at the target position of the inner drum.
[0094] Figure 9 : is a structural block diagram of a washing machine according to an embodiment of the present invention. Figure 9 As shown, the washing machine includes: an inner drum 90, a plurality of washing compartments 92 assembled inside the inner drum, and a controller 94. The inner drum is connected to each washing compartment through an openable and closable isolation door. The controller is used to perform the functions of any one of the above embodiments.
[0095] In one example, the multiple washing tanks have the same cabin structure and are evenly distributed in an annular shape on the inner wall of the inner cylinder.
[0096] The structure in this example is that three small washing compartments (washing compartments 1, 2, and 3) can be divided in the inner drum for washing different types of clothes. The three washing compartments are 120° apart. The purpose is to enable the washing machine to maintain its center of gravity during operation and prevent it from hitting the drum. The structure of the three washing compartments is the same, that is, the shape, volume, and material are the same.
[0097] In one example, the compartment of the separate washing tank extends from low to high inside the inner tube from the inner side to the outer side of the inner tube, the inner side is connected to the drain port of the inner tube, and the outer side is connected to the hatch of the inner tube.
[0098] In one example, the inner barrel has an extended length greater than the extended length of the separation tank.
[0099] Figure 10 This is the structure of the washing machine washing compartment in the embodiment of the present invention Figure 2 , illustrating the following partial structure: drain outlet 2, washing compartment 3, sliding door spring 14, washing compartment door 15, and sliding door spring 16. The drain outlet is mounted on the inside of the inner drum, while the washing compartment door 15 is mounted on the outside of the inner drum. The sliding door spring 14 and sliding door spring 16 cooperate to open and close the door. The entire washing compartment is inclined from the inside to the outside (i.e., the height of the rear of the washing compartment is less than that of the front of the washing compartment). Therefore, when washing is complete, gravity inertia can be used to drop clothes back into the inner drum. The washing compartment is completely contained within the inner drum, that is, the length of each washing compartment is less than the length of the inner drum.
[0100] Optionally, one or more washing compartments of the washing machine are equipped with a heating device, which is used to heat the washing compartment separately. The inner drum is also equipped with a heating device to achieve separate heating during the washing process. The heating device can be a heating rod.
[0101] In one example, the washing compartment is also equipped with a door control device, which controls the opening and closing of the washing compartment water inlet, drain outlet and isolation compartment door through electromagnetic rods. Multiple electromagnetic rods are set, one on the front and back sides of the washing machine outer tub, one for controlling the water inlet door and one for controlling the washing compartment door. An infrared transmitter and receiver are attached to the electromagnetic rod on the rear side of the outer tub. Figure 11 1 is a front view of a washing machine according to an embodiment of the present invention, Figure 12 This is a rear view of a washing machine according to an embodiment of the present invention. A magnet with opposite magnetic properties to the electromagnetic rod 8 (first electromagnetic rod) is attached to the water inlet door 10. A controller controls the charge of the electromagnetic rod, thereby utilizing magnetism to control the state of the water inlet door 10. Similarly, the drain outlet door 17 also utilizes magnetism to control the charge of the electromagnetic rods 18 (second electromagnetic rod) and 20 (third electromagnetic rod). The difference is that when drain outlet door 17 is to be opened, the electromagnetic rod 18 and the magnets on drain outlet door 17 are magnetically aligned, pushing the door to the right to open it. To close the door, the electromagnetic rod 20 and the magnets on drain outlet door 17 are magnetically aligned, pushing the door back to close it. The heating device placement area 19 is used to house the heating device, which provides independent heating for each washing compartment. When washing and dehydration are completed, the controller controls the charge of the electromagnetic rod 8, and further controls whether it is magnetized. The door switch 6 has a magnet with the same magnetic properties as the electromagnetic rod 8. When the electromagnetic rod is charged, the door switch 6 is pressed down by the principle of magnetic repulsion, and the door is opened. When the electromagnetic rod is energized again, the door switch 6 is pressed down again, and the door is closed.
[0102] It should be noted that the above modules can be implemented through software or hardware. For the latter, it can be implemented in the following ways, but not limited to: the above modules are all located in the same processor; or the above modules are located in different processors in any combination.
