Technical Field

[0001] The present invention relates to the technical field of washing equipment, and specifically provides a control method for a washing equipment combination and a washing equipment combination. Background Art

[0002] With the development of technology and the continuous improvement of user needs, the functions and uses of washing equipment are becoming more and more abundant, making the originally heavy laundry work simpler and easier.

[0003] For example, the combination of multiple washing machines is becoming more and more popular among users. It is composed of multiple washing machines with different functions, which can realize the classified washing, drying and care of different clothes, improving the efficiency of clothing washing and care. At the same time, the stacking method can save space and improve the indoor space utilization.

[0004] However, when multiple washing machines in an existing washing machine combination are simultaneously executing a dehydration mode, resonance is easily generated, resulting in excessive amplitude of the washing machine combination, which affects stability and safety during operation.

[0005] Therefore, this field needs a new technical solution to solve the above problems. Summary of the Invention

[0006] The present invention aims to solve the above technical problem, namely, the technical problem that multiple washing machines in the existing washing machine combination are prone to resonance when executing the dehydration mode at the same time, resulting in excessive amplitude of the washing machine combination, affecting the stability and safety during operation.

[0007] In a first aspect, the present invention provides a control method for a washing device combination, the washing device combination comprising: a first washing device and a second washing device, the first washing device having a first inner drum, the second washing device having a second inner drum, the first washing device being located on top of the second washing device, the control method comprising: when both the first washing device and the second washing device are performing a dehydration mode, controlling the speed difference or phase difference between the first inner drum and the second inner drum to avoid resonance between the first washing device and the second washing device.

[0008] In a preferred technical solution of the above-mentioned control method, one of the first inner drum and the second inner drum rotates around a horizontal axis, and the other of the first inner drum and the second inner drum rotates around a vertical axis. The specific step of "controlling the speed difference or phase difference between the first inner drum and the second inner drum to avoid resonance between the first washing device and the second washing device" includes: maintaining a certain speed difference between the first inner drum and the second inner drum.

[0009] In a preferred technical solution of the above control method, the specific step of "maintaining a certain rotational speed difference between the first inner tube and the second inner tube" includes: maintaining the rotation of one of the first inner tube and the second inner tube, and stopping the rotation of the other of the first inner tube and the second inner tube.

[0010] In a preferred technical solution of the above-mentioned control method, the first inner drum and the second inner drum both rotate around a horizontal axis or a vertical axis, and the specific steps of "controlling the speed difference or phase difference between the first inner drum and the second inner drum to avoid resonance between the first washing device and the second washing device" include: obtaining the direction of the centrifugal force acting on the first inner drum, recorded as the first direction; obtaining the direction of the centrifugal force acting on the second inner drum, recorded as the second direction; making the speeds of the first inner drum and the second inner drum equal, and maintaining a certain phase difference between the first direction and the second direction.

[0011] In a preferred technical solution of the above control method, the phase difference is set to 180 degrees.

[0012] In a preferred technical solution of the above-mentioned control method, before executing the dehydration mode, the control method further includes: obtaining the weight of the clothes in the first inner drum, recorded as a first weight; based on the first weight, selectively rotating the first inner drum intermittently to beat and shake the clothes; and / or obtaining the weight of the clothes in the second inner drum, recorded as a second weight; based on the second weight, selectively rotating the second inner drum intermittently to beat and shake the clothes.

[0013] In the preferred technical solution of the above-mentioned control method, the specific steps of "selectively rotating the first inner drum intermittently to beat and shake the clothes according to the first weight" include: comparing the first weight with a first preset weight; and selectively rotating the first inner drum intermittently to beat and shake the clothes according to the comparison result; and / or the specific steps of "selectively rotating the second inner drum intermittently to beat and shake the clothes according to the second weight" include: comparing the second weight with a second preset weight; and selectively rotating the second inner drum intermittently to beat and shake the clothes according to the comparison result.

[0014] In the preferred technical solution of the above-mentioned control method, the specific steps of "selectively rotating the first inner drum intermittently to beat and shake the clothes according to the comparison result" include: if the first weight is greater than the first preset weight, rotating the first inner drum intermittently; if the first weight is not greater than the first preset weight, not rotating the first inner drum intermittently; and / or the specific steps of "selectively rotating the second inner drum intermittently to beat and shake the clothes according to the comparison result" include: if the second weight is greater than the second preset weight, rotating the second inner drum intermittently; if the second weight is not greater than the second preset weight, not rotating the second inner drum intermittently.

[0015] In a second aspect, the present invention further provides a washing device combination, comprising a controller configured to execute the above-mentioned control method.

[0016] In a preferred technical solution of the above-mentioned washing device combination, the first washing device is configured as a washing machine, and the second washing device is configured as a shoe washing machine.

[0017] In the case of adopting the above technical solution, the washing machine combination of the present invention includes: a first washing machine and a second washing machine, the first washing machine having a first inner drum, the second washing machine having a second inner drum, the first washing machine being located on top of the second washing machine, and the control method of the present invention comprising: when both the first washing machine and the second washing machine are in a dehydration mode, controlling the rotation speed difference or phase difference between the first inner drum and the second inner drum to avoid resonance between the first washing machine and the second washing machine. This arrangement, on the one hand, enriches the functions and uses of the washing machine and saves storage space; on the other hand, it prevents resonance when the two machines are simultaneously dehydrating, effectively suppresses the vibration intensity and operating noise of the washing machine combination, improves the stability of the washing machine combination during operation, and is conducive to extending the service life. It also prevents the washing machine combination from shaking, shifting, or even tipping over due to the superposition of vibrations from the two machines, thereby improving the safety of the operation of the equipment; and further, improves the dehydration efficiency of the clothes.

[0018] Furthermore, in the present invention, one of the first and second inner drums rotates about a horizontal axis, while the other rotates about a vertical axis. The control method of the present invention also includes maintaining a certain rotational speed difference between the first and second inner drums. This arrangement increases the flexibility of combining different types of washing machines. Furthermore, for two washing machines with different rotation axis orientations, the first and second inner drums can be prevented from rotating at the same frequency, thus preventing resonance between the two and increasing the amplitude of vibration. This effectively controls the vibration intensity and operating noise of the washing machine combination.

[0019] Furthermore, the control method of the present invention further includes: maintaining rotation of one of the first and second inner drums while stopping rotation of the other. This arrangement allows only one of the devices to remain in operation when the vibration amplitudes of both devices are relatively large. This prevents the vibration amplitude of the washing machine assembly from being amplified by the combined vibrations of the two devices, thereby controlling the overall vibration amplitude of the washing machine assembly within a relatively small range, further controlling the vibration intensity and operating noise of the washing machine assembly, and ensuring the overall stability of the washing machine assembly.

[0020] Furthermore, the first inner drum and the second inner drum of the present invention both rotate about a horizontal axis or a vertical axis, and the control method of the present invention further includes: obtaining the direction of the centrifugal force acting on the first inner drum, recorded as the first direction; obtaining the direction of the centrifugal force acting on the second inner drum, recorded as the second direction; and making the rotational speeds of the first inner drum and the second inner drum equal, and maintaining a certain phase difference between the first direction and the second direction. This arrangement improves the flexibility of combining different types of washing equipment. For two washing equipment with the same rotation axis direction, the centrifugal force acting on the first inner drum and the centrifugal force acting on the second inner drum are prevented from superimposing on each other and significantly increasing the vibration amplitude of the washing equipment combination, thereby controlling the vibration intensity and operating noise of the washing equipment combination and ensuring the overall stability of the washing equipment combination.

[0021] Furthermore, the phase difference of the present invention is set to 180 degrees. This setting not only prevents the centrifugal force on the first inner drum from being superimposed on the centrifugal force on the second inner drum, but also makes them cancel each other out, further reducing the vibration amplitude and operating noise of the entire washing equipment assembly, and ensuring the overall stability of the washing equipment assembly.

[0022] Furthermore, before executing the dehydration mode, the control method of the present invention also includes: obtaining the weight of the clothes in the first inner drum, recorded as the first weight; based on the first weight, selectively rotating the first inner drum intermittently to beat and shake the clothes; and / or obtaining the weight of the clothes in the second inner drum, recorded as the second weight; based on the second weight, selectively rotating the second inner drum intermittently to beat and shake the clothes. Through such a setting, on the one hand, the clothes can be dehydrated to a certain extent by beating and shaking, reducing the water content and total weight of the clothes, thereby reducing the eccentricity of the inner drum during the rotation process, and effectively controlling the centrifugal force applied to the inner drum; on the other hand, it can prevent the clothes from gathering on one side of the inner drum and increasing the eccentricity of the inner drum during the rotation process, control the centrifugal force applied to the inner drum, and improve the dehydration efficiency of the clothes.

[0023] Furthermore, the control method of the present invention further includes: comparing the first weight with a first preset weight; and based on the comparison result, selectively causing the first inner drum to intermittently rotate to tumble and shake the clothes; and / or the control method of the present invention further includes: comparing the second weight with a second preset weight; and based on the comparison result, selectively causing the second inner drum to intermittently rotate to tumble and shake the clothes. Through such an arrangement, the first preset weight and the second preset weight can accurately assess the weight of the clothes to predict the centrifugal force and amplitude generated by clothes of different weights, and then determine whether it is necessary to control the inner drum to rotate intermittently before the dehydration mode based on the comparison result of the actual weight of the clothes and the preset weight.

[0024] Furthermore, the control method of the present invention further includes: if the first weight is greater than a first preset weight, causing the first inner drum to rotate intermittently; if the first weight is not greater than the first preset weight, preventing the first inner drum from intermittently rotating; and / or the control method of the present invention further includes: if the second weight is greater than a second preset weight, causing the second inner drum to rotate intermittently; if the second weight is not greater than the second preset weight, preventing the second inner drum from intermittently rotating. Through such an arrangement, the amount of water removed from the laundry can be increased when the laundry weight is heavy, reducing the eccentricity and centrifugal force of the inner drum rotation; and the ability to directly enter spin mode when the laundry weight is light, thereby improving dehydration efficiency and reducing device power consumption.

[0025] In addition, the washing equipment combination further provided by the present invention on the basis of the above-mentioned technical solution adopts the above-mentioned control method, and thus has the technical effects possessed by the above-mentioned control method. Compared with the washing equipment combination before the improvement, the washing equipment combination of the present invention can avoid resonance between multiple washing equipment during the spin dehydration process, and thus can effectively control the vibration intensity and noise level of the washing equipment combination, thereby improving the stability and safety of the washing equipment combination.

[0026] Furthermore, the first washing device of the present invention is configured as a washing machine, and the second washing device is configured as a shoe washer. This configuration improves the flexibility of the washing device combination, enriches the functions and uses of the washing device combination, and enables the classified drying and washing of different clothes to meet the different needs of users.

[0036] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0038] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "disposed," "connected," and "installed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] Based on the technical problem pointed out in the background art that multiple washing machines in an existing washing machine combination are prone to resonance when simultaneously executing a dehydration mode, resulting in excessive amplitude of the washing machine combination, which affects the stability and safety during operation. To this end, the present invention provides a control method and a washing machine combination, wherein the washing machine combination includes a first washing machine and a second washing machine, and the control method includes: when the first washing machine and the second washing machine are both executing a dehydration mode, controlling the speed difference or phase difference between the first inner drum and the second inner drum to avoid resonance between the first washing machine and the second washing machine.

[0040] Specifically, if Figures 1 to 4 As shown, the washing equipment combination of the present invention includes: a first washing equipment 1 and a second washing equipment 2, the first washing equipment 1 has a first inner drum 11, the second washing equipment 2 has a second inner drum 21, and the first washing equipment 1 is located on top of the second washing equipment 2. The control method of the present invention includes:

[0041] S100: When the first washing device and the second washing device both perform a dehydration mode, controlling a rotation speed difference or a phase difference between the first inner drum and the second inner drum to avoid resonance between the first washing device and the second washing device.

[0042] Exemplarily, the second washing device 2 is placed on the ground, and the first washing device 1 is stacked on top of the second washing device 2, thereby reducing the floor space of the washing device combination and improving space utilization. The first washing device 1 has a first motor driven by the first inner drum 11, and the second washing device 2 has a second motor driven by the second inner drum 21. The first inner drum 11 and the second inner drum 21 rotate at high speed respectively driven by the first motor and the second motor to drive out the moisture in the clothes, thereby realizing the dehydration operation of the clothes.

[0043] The traditional washing equipment combination simply stacks multiple washing equipment to save space, while the control and operation of each equipment remain relatively independent and do not affect each other. Through actual application, it is found that when both washing equipment are executing the dehydration mode, the first inner drum 11 and the second inner drum 21 are respectively driven by the first motor and the second motor to rotate at high speed. Due to the uneven weight distribution of the clothes in the inner drum and the outward centrifugal force during the high-speed rotation, the first inner drum 11 and the second inner drum 21 have a certain eccentricity. The eccentric rotation of the first inner drum 11 and the second inner drum 21 will produce violent vibration, and the vibration intensity will increase with the increase of the rotation speed.

[0044] If the rotational speeds of the first inner drum 11 and the second inner drum 21 are equal, the directions of the centrifugal forces acting on them may be the same, which will cause the centrifugal forces to be superimposed on each other in the same direction, greatly increasing the vibration amplitude of the entire washing equipment assembly. Especially when the weight of the clothes is heavy, it will cause the washing equipment assembly to shake, shift, or even tip over, increasing the instability and safety risks of the washing equipment assembly.

[0045] Based on this, the washing equipment combination of the present invention has a central control unit and various sensing devices, which can monitor the operating status of each washing equipment and comprehensively manage and control each washing equipment based on the monitoring results to optimize the operating status of the washing equipment combination and improve operating efficiency.

[0046] Exemplarily, the control method of the present invention controls the rotational speed difference or phase difference (wherein the phase difference specifically refers to the phase difference between the direction of the centrifugal force exerted on the first inner drum 11 and the direction of the centrifugal force exerted on the second inner drum 21 during the rotation process) between the first inner drum 11 and the second inner drum 21, so that the direction of the centrifugal force exerted on the first inner drum 11 and the direction of the centrifugal force exerted on the second inner drum 21 will not always be consistent, thereby avoiding the two centrifugal forces generating a resultant force in the same direction and significantly increasing the vibration amplitude and noise of the washing equipment combination.

[0047] Therefore, the washing equipment combination of the present invention not only enriches the functions and uses of the equipment and saves placement space; it can also prevent resonance when the two equipment are rotating and dehydrating at the same time, effectively suppress the vibration intensity and operating noise of the washing equipment combination, improve the stability of the washing equipment combination during operation, and is conducive to extending the service life. At the same time, it can prevent the washing equipment combination from shaking, shifting or even tipping over due to the superposition of vibrations of the two equipment, thereby improving the safety of equipment operation and dehydration efficiency.

[0048] Preferably, if Figure 1 As shown, one of the first inner drum 11 and the second inner drum 21 of the present invention rotates about a horizontal axis, and the other of the first inner drum 11 and the second inner drum 21 rotates about a vertical axis. The specific steps of "controlling the speed difference or phase difference between the first inner drum and the second inner drum to avoid resonance between the first washing device and the second washing device" include:

[0049] S110: Maintaining a certain rotation speed difference between the first inner drum and the second inner drum.

[0050] The inner drum of a drum washing machine usually rotates around a horizontal axis, and the inner drum of a pulsator washing machine usually rotates around a vertical axis. Therefore, when a pulsator washing machine and a drum washing machine are combined, although the directions of the rotation axes of the two are different, the centrifugal force exerted on the first inner drum 11 and the centrifugal force exerted on the second inner drum 21 may still form a resultant force in the same direction. For example, Figure 1As shown, the first inner drum 11 rotates around the horizontal axis and the second inner drum 21 rotates around the vertical axis. When the rotation speeds of the first inner drum 11 and the second inner drum 21 are equal, if the clothes in the first inner drum 11 rotate to the position closest to the first side plate 12, and the clothes in the second inner drum 21 just rotate to the position closest to the second side plate 22, then the centrifugal force exerted on the first inner drum 11 and the centrifugal force exerted on the second inner drum 21 are both in the horizontal direction and in the same direction. Since the rotation speeds of the first inner drum 11 and the second inner drum 21 are equal, the clothes in the first inner drum 11 and the clothes in the second inner drum 21 will form a resultant force in opposite directions after they are respectively rotated 180 degrees, thereby causing the two centrifugal forces to be superimposed in the horizontal direction, thereby increasing the vibration amplitude of the washing device combination.

[0051] Based on this, in order to avoid the occurrence of the above situation, the control method of the present invention adopts a solution of maintaining a certain speed difference between the first inner drum 11 and the second inner drum 21. This not only prevents the first inner drum 11 and the second inner drum 21 from rotating at the same frequency, but also prevents the centrifugal forces acting on the two from forming a resultant force in the same direction, prevents the vibration from being aggravated due to resonance between the two, and effectively controls the vibration amplitude and operating noise of the washing equipment combination.

[0052] It should be noted that, with regard to how to determine the direction of the centrifugal force of the first inner drum 11 and the second inner drum 21, the present invention provides two preferred implementation modes. In the first preferred implementation mode, a circle of pressure sensors are circumferentially arranged on the outer sides of the inner drums of the first washing device 1 and the second washing device 2. Since the centrifugal force generated at the position where the clothes pass through is the largest during the rotation of the inner drum, the pressure signal sensed at this position is also the strongest. By obtaining the pressure signal, the change in the direction of the centrifugal force can be accurately obtained.

[0053] In a second embodiment of the present invention, distance measuring sensors are provided circumferentially between the inner drum and the washing machine body of the first washing device 1 and the second washing device 2, respectively, so as to detect the distance between the outer wall of the inner drum and the washing machine body in real time. Since the centrifugal force generated at the position where the clothes pass is the largest, the distance between this position and the washing machine body becomes smaller, and the direction change of the centrifugal force is determined according to the change of the distance signal.

[0054] Such flexible adjustment and change do not deviate from the principle and scope of the present invention and should be limited within the scope of protection of the present invention. In this case, the pressure sensor solution is preferably adopted.

[0055] Preferably, if Figure 1 and Figure 5 As shown, the specific steps of "maintaining a certain rotation speed difference between the first inner cylinder and the second inner cylinder" include:

[0056] S111: Keep rotating one of the first inner cylinder and the second inner cylinder, and stop rotating the other one of the first inner cylinder and the second inner cylinder.

[0057] By maintaining a certain speed difference between the first inner drum 11 and the second inner drum 21, resonance between the two can be avoided and the vibration intensity of the washing device combination can be reduced to a certain extent. However, the effect of reducing high-frequency vibration is limited. In particular, when the weight of the clothes in the first inner drum 11 and the second inner drum 21 is large, the vibration amplitude will also increase accordingly.

[0058] In this case, the control method of the present invention preferably adopts a method of keeping only one device in operation, that is, first one of the washing devices executes the dehydration program, and the other washing device waits. After one washing device completes the dehydration program, the other washing device executes the dehydration program. This can avoid the amplitude of the washing device combination being aggravated due to the superposition of vibrations between the two, thereby controlling the overall vibration amplitude of the washing device combination within a smaller range, further controlling the vibration amplitude and operating noise of the washing device combination, and ensuring the overall stability of the washing device combination.

[0059] Preferably, if Figure 2 and Figure 6 As shown, the first inner drum 11 and the second inner drum 21 of the present invention both rotate around a horizontal axis or a vertical axis, and the specific steps of "controlling the speed difference or phase difference between the first inner drum and the second inner drum to avoid resonance between the first washing device and the second washing device" include:

[0060] S110: Obtain the direction of the centrifugal force acting on the first inner cylinder, recorded as a first direction;

[0061] S120: Obtain the direction of the centrifugal force on the second inner cylinder, recorded as the second direction;

[0062] S130: The rotational speeds of the first inner cylinder and the second inner cylinder are made equal, and a certain phase difference is maintained between the first direction and the second direction.

[0063] For example, in daily use, there may also be a combination of two drum washing machines or a combination of two pulsator washing machines, such as Figure 2As shown, this case takes a combination of two drum washing machines as an example. When the rotation axes of the first inner drum 11 and the second inner drum 21 are consistent, the control method of the present invention controls the rotation speeds of the first inner drum 11 and the second inner drum 21 by respectively detecting the directions of the centrifugal forces acting on the first inner drum 11 and the second inner drum 21 in real time, so as to make the rotation speeds of the first inner drum 11 and the second inner drum 21 equal and maintain a certain phase difference between the first direction and the second direction, thereby preventing the centrifugal forces acting on the first inner drum 11 and the second inner drum 21 from being superimposed on each other and significantly increasing the vibration amplitude of the washing equipment combination, thereby controlling the vibration intensity and operating noise of the washing equipment combination and ensuring the overall stability of the washing equipment combination.

[0064] Preferably, the phase difference of the present invention is set to 180 degrees.

[0065] The first direction and the second direction always maintain a phase difference of 180 degrees, that is, the position of the clothes in the first inner drum 11 and the position of the clothes in the second inner drum 21 are always located on opposite sides of the inner barrel. This arrangement can not only prevent the centrifugal force exerted on the first inner drum 11 and the centrifugal force exerted on the second inner drum 21 from being superimposed on each other, but also can make the two cancel each other out, further reducing the vibration amplitude and operating noise of the entire washing equipment combination, and ensuring the overall stability of the washing equipment combination.

[0066] Preferably, before executing the dehydration mode, the control method of the present invention further includes:

[0067] Obtain the weight of the clothes in the first inner drum, recorded as the first weight;

[0068] selectively rotating the first inner drum intermittently according to the first weight to beat and shake the clothes; and / or

[0069] Obtain the weight of the clothes in the second inner drum, which is recorded as the second weight;

[0070] According to the second weight, the second inner drum is selectively rotated intermittently to beat and shake the clothes.

[0071] Illustratively, the first washing device 1 and the second washing device 2 of the present invention can both control the motor to drive the inner drum to rotate intermittently, that is, control the inner drum to rotate to a certain speed and then stop suddenly, and can first rotate the clothes to a certain height, and then make the clothes fall to the bottom of the inner drum, and repeat multiple times, thereby achieving a certain degree of dehydration of the clothes, reducing the water content and total weight of the clothes, and then reducing the eccentricity of the inner drum during the rotation process, so that the centrifugal force exerted on the inner drum is effectively controlled; in addition, it can also break up and shake out the clothes that are gathered together to avoid the clothes gathering on one side of the inner drum and increasing the eccentricity of the inner drum during the rotation process, control the centrifugal force exerted on the inner drum, and improve the dehydration efficiency of the clothes.

[0072] Preferably, the specific step of “selectively rotating the first inner drum intermittently according to the first weight to beat and shake the clothes” includes:

[0073] comparing the first weight with a first preset weight;

[0074] According to the comparison result, selectively rotating the first inner drum intermittently to beat and shake the clothes; and / or

[0075] The specific steps of “selectively rotating the second inner drum intermittently according to the second weight to beat and shake the clothes” include:

[0076] comparing the second weight with a second predetermined weight;

[0077] According to the comparison result, the second inner drum is selectively rotated intermittently to beat and shake the clothes.

[0078] The first preset weight and the second preset weight can accurately evaluate the weight of the clothes to predict the centrifugal force and amplitude generated by clothes of different weights. Then, based on the comparison result between the actual weight of the clothes and the preset weight, it can be determined whether it is necessary to control the intermittent rotation of the inner drum before the dehydration mode to beat and shake the clothes.

[0079] It should be noted that, in actual applications, according to the capacity of the equipment, those skilled in the art can flexibly set the values ​​of the first preset weight and the second preset weight. In this case, it is preferred to set the values ​​of the first preset weight and the second preset weight to between 4kg and 6kg.

[0080] Preferably, the specific step of “selectively rotating the first inner drum intermittently according to the comparison result to beat and shake the clothes” includes:

[0081] If the first weight is greater than a first preset weight, causing the first inner drum to rotate intermittently;

[0082] If the first weight is not greater than the first preset weight, not intermittently rotating the first inner drum; and / or

[0083] The specific steps of “selectively rotating the second inner drum intermittently based on the comparison result to beat and shake the clothes” include:

[0084] If the second weight is greater than the second preset weight, the second inner drum is caused to rotate intermittently;

[0085] If the second weight is not greater than the second preset weight, the second inner drum is not intermittently rotated.

[0086] For example, when the actual weight of the clothes in the inner drum is greater than the preset weight, it means that the centrifugal force exerted on the inner drum during high-speed rotation will affect the stable operation of the washing device, and the clothes need to be thrown and shaken before the dehydration mode.

[0087] When the actual weight of the clothes in the inner drum is not greater than the preset weight, it means that the centrifugal force exerted on the inner drum during high-speed rotation has limited impact on the stable operation of the washing equipment, and will not cause obvious shaking, so the washing machine can directly enter the dehydration mode.

[0088] Through such a setting, the dehydration amount of clothes can be increased when the weight of clothes is heavy, and the eccentricity and centrifugal force of the inner drum rotation can be reduced; and the dehydration mode can be directly entered when the weight of clothes is light, thereby improving the dehydration efficiency and reducing the power consumption of the equipment.

[0089] In addition, the washing equipment combination further provided by the present invention on the basis of the above-mentioned technical solution adopts the above-mentioned control method, and thus has the technical effects possessed by the above-mentioned control method. Compared with the washing equipment combination before the improvement, the washing equipment combination of the present invention can avoid resonance between multiple washing equipment during the spin dehydration process, and thus can effectively control the vibration intensity and noise level of the washing equipment combination, thereby improving the stability and safety of the washing equipment combination.

[0090] Preferably, the first washing device 1 of the present invention is configured as a washing machine, and the second washing device 2 is configured as a shoe washing machine. This improves the flexibility of the washing device combination, enriches the functions and uses of the washing device combination, realizes the classified drying and washing of different clothes, and meets the different needs of users.

[0091] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
