[0024] This embodiment provides a washing machine, such as Figure 1-Figure 3 As shown, the washing machine comprises an outer drum 11 and an inner drum 12 rotatably mounted in the outer drum 11, and the outer drum 11 is arranged in a housing 13. The outer drum 11 and the inner drum 12 are respectively composed of a cylindrical outer drum side wall and an inner drum side wall, and the corresponding ends on the same side of the outer drum 11 and the inner drum 12 are provided with openings opened opposite to each other to form an inner drum opening and an outer drum opening respectively, and the corresponding ends on the other side are both sealed to form an inner drum bottom and an outer drum bottom respectively. At the same time, a door cover 14 that can be opened outward is installed at the front end of the washing machine housing, so as to close the inner drum opening after the door cover 14 is closed, and to put clothes into the inner drum 12 from the inner drum opening after the door cover 14 is opened. The center of the inner drum bottom is coaxially arranged with the motor shaft of the washing machine driving motor to drive the inner drum 12 to rotate, and the inner drum 12 and the driving motor are both fixedly mounted on the outer drum 11.

[0025] Preferably, the bottom of the inner drum and the driving motor are respectively arranged on both sides of the bottom of the outer drum, the driving motor is fixedly connected to the outer drum 11, the motor shaft of the driving motor passes through the bottom of the outer drum via a bearing, and is coaxially fixedly connected to the bottom of the inner drum, and the motor shaft of the driving motor can rotate relative to the outer drum 11, so as to achieve the purpose of installing the inner drum 12 and the driving motor on the outer drum, and allowing the inner drum 12 to rotate independently under the action of the driving motor to wash the clothes inside. Preferably, the motor shaft of the driving motor directly constitutes the inner drum shaft, and the inner drum shaft is coaxially fixedly connected to the inner drum bottom of the inner drum 12.

[0026] There is a certain gap between the bottom of the inner cylinder and the bottom of the outer cylinder to ensure that the inner cylinder 12 will not be blocked by the friction of the outer cylinder 11 during the rotation process.

[0027] The washing machine of this embodiment further includes an outer drum cleaning device 16, which includes a cleaning portion 161 and a driving mechanism 162. The driving mechanism 162 is disposed on the inner drum 12, and the driving mechanism 162 is at least used to drive the cleaning portion 161 to move between a first position and a second position. When the cleaning portion 161 is in the first position, the cleaning portion 161 contacts the inner wall of the outer drum, and when it is in the second position, the cleaning portion 161 is separated from the inner wall of the outer drum.

[0028] When the cleaning part 161 is in the first position, that is, when the cleaning part 161 contacts the inner wall of the outer cylinder, by controlling the rotation of the inner cylinder 12, the inner cylinder 12 can drive the cleaning part 161 to rotate together, and the cleaning part 161 performs 360° cleaning on the inner wall of the outer cylinder. In particular, for dirt attached to the inner wall surface that is not easily washed away by water flow, the cleaning part 161 directly contacts the inner wall of the outer cylinder and generates friction, so that the cleaning is more thorough.

[0029] The outer cylinder cleaning device 16 can be arranged on the side wall of the inner cylinder, or on the bottom of the inner cylinder. When the outer cylinder cleaning device 16 is arranged on the side wall of the inner cylinder, it can clean the inner side wall of the outer cylinder as the inner cylinder 12 rotates. When the outer cylinder cleaning device 16 is arranged on the bottom of the inner cylinder, it can clean the inner side of the bottom of the outer cylinder as the inner cylinder 12 rotates.

[0030] Of course, the outer cylinder cleaning device 16 may also be provided on the inner cylinder side wall and the inner cylinder bottom respectively, so as to clean the inner surface of the outer cylinder at the same time.

[0031] The driving rod 1621 has a first end and a second end that are opposite to each other.

[0032] In some embodiments, the driving mechanism 162 includes a driving rod 1621, a through portion (not shown in the figure due to angle reasons) is provided on the inner cylinder 12 to guide and cooperate with the driving rod 1621, the cleaning portion 161 is located between the outer cylinder 11 and the inner cylinder 12, and the first end of the driving rod 1621 passes through the through portion and is connected to the cleaning portion 161. The driving mechanism 162 drives the driving rod 1621 to move, and then drives the cleaning portion 161 to move through the driving rod 1621.

[0033] The driving rod 1621 can perform telescopic movement to push the cleaning portion 161 to move to the first position, or return to the second position.

[0034] In some embodiments, the driving mechanism 162 further includes an armature 1622, an electromagnet 1623, an elastic mechanism 1624, and a power module, wherein the armature 1622 is fixed to the second end of the driving rod 1621. The armature 1622 can be attracted by magnetic force, and when the magnetic attraction force is large enough, it can move under the action of the magnetic attraction force.

[0035] The electromagnet 1623 is arranged opposite to the armature 1622. When the electromagnet 1623 is energized, it generates a magnetic attraction force on the armature 1622, and the armature 1622 can move toward the electromagnet. Since the armature 1622 is fixedly connected to the driving rod 1621, the armature 1622 drives the cleaning part 161 to move to the first position through the driving rod 1621, and the cleaning part 161 contacts the inner wall of the outer tube.

[0036] There are only two relationships between the electromagnet 1623 and the armature 1622: magnetic attraction and no magnetic attraction. In order to enable the cleaning part 161 to retreat to the second position and be separated from the inner wall of the outer cylinder when the inner wall of the outer cylinder does not need to be cleaned, an elastic mechanism 1624 is provided, which is connected between the inner wall of the inner cylinder 12 and the armature 1622. When the armature 1622 is not attracted by the magnetic attraction, the elastic mechanism 1624 is used to support the armature 1622, so that the cleaning part 161 remains in the second position. When the electromagnet 1623 is energized, it generates a magnetic attraction on the armature 1622, and the armature 1622 compresses the elastic mechanism 1624 to move toward the electromagnet.

[0037] When the electromagnet 1623 is powered off, the magnetic attraction force on the armature 1622 disappears, the elastic mechanism 1624 is reset, the armature 1622 moves in a direction away from the electromagnet 1623 , and drives the cleaning portion 161 to move to the second position through the driving rod 1621 .

[0038] The power module is controlled by the control module to supply power to the electromagnet 1623 or cut off the power supply.

[0039] In some embodiments, the armature 1622 can also be replaced by a permanent magnet. By controlling the polarity of the surface opposite to the permanent magnet when the electromagnet 1623 is energized, a magnetic attraction force can be generated to attract the permanent magnet, thereby driving the cleaning portion 161 to the first position.

[0040] In addition, when a permanent magnet is used, when the cleaning part 161 needs to be reset to the second position, the electromagnet 1623 can also be controlled to have the same surface polarity as that of the permanent magnet when energized, thereby generating a magnetic repulsive force on the permanent magnet to repel it and assist in resetting the cleaning part 161 to the first position.

[0041] In some embodiments, the elastic mechanism 1624 can be implemented by a spring, or by an object with an elastic structure, such as sponge, memory foam, etc.

[0042] When the elastic mechanism 1624 is a spring, it is sleeved on the outside of the driving rod 1621 .

[0043] In some embodiments, the driving mechanism 162 also includes a shell 1625, and the armature 1622, the electromagnet 1623, the elastic mechanism 1624 and the power module are sealed in the shell 1625. A through hole for accommodating the driving rod 1621 to pass through is opened on the bottom wall of the shell 1625, and a sealing rubber ring is provided in the through hole. The driving rod 1621 fits tightly with the sealing rubber ring, which can prevent water in the outer cylinder from entering the shell 1625, so as to protect the internal structure from being corroded by water.

[0044] In some embodiments, lifting ribs 121 are formed on the inner wall of the inner drum 12, which are used to utilize friction to lift the clothes to a certain height and then beat them when the inner drum 12 rotates, so as to achieve the effect of washing the clothes. An accommodating cavity 122 is formed in the lifting ribs 121, and the driving mechanism 162 is arranged in the accommodating cavity 122. The through portion is opened on the wall of the inner drum and is connected to the accommodating cavity.

[0045] In some embodiments, since the outer cylinder cleaning device 16 needs to rotate with the inner cylinder 12 and is not conveniently connected to an external circuit via wires, the outer cylinder cleaning device 16 also includes a wireless communication module to communicate with an external control module via wireless signals.

[0046] The washing machine further comprises a turbidity detection element, which is arranged in the outer tub 11 and is used to detect the turbidity of water and send it to the main control module.

[0047] The wireless communication module is used to receive control signals from the main control module or the mobile communication module; When the wireless communication module is used to receive the control signal from the mobile communication module, the general control module sends the control signal to the mobile communication module through the cloud server.

[0048] The turbidity of the water detected by the turbidity detection element is used to judge the dirtiness in the barrel, and the working state of the outer barrel cleaning device 16 is controlled accordingly.

[0049] In some embodiments, the cleaning portion 161 is a brush extending along the length direction of the inner drum 12, and the bristles of the brush are arranged toward the inner wall direction of the outer drum 11. Under normal circumstances, when the inner drum 11 of the washing machine rotates, the clothes in the inner drum 11 rotate in the inner drum 11 driven by the water flow, and the bristles of the brush collide and rub against the inner wall of the outer drum 11, which can scrub the dirt on the inner wall of the outer drum 11 and carry it away by the water flow, which can effectively improve the cleaning effect of the washing machine. Example

[0050] This embodiment provides a method for controlling a washing machine. Figure 1-Figure 3 As shown, the housing 13 includes an outer cylinder 11 and an inner cylinder 12 rotatably installed in the outer cylinder 11 , and the outer cylinder 11 is disposed in a housing 13 .

[0051] There is a certain gap between the bottom of the inner cylinder and the bottom of the outer cylinder to ensure that the inner cylinder 12 will not be blocked by the friction of the outer cylinder 11 during the rotation process.

[0052] The washing machine of this embodiment further includes an outer drum cleaning device 16, which includes a cleaning portion 161 and a driving mechanism 162. The driving mechanism 162 is disposed on the inner drum 12, and the driving mechanism 162 is at least used to drive the cleaning portion 161 to move between a first position and a second position. When the cleaning portion 161 is in the first position, the cleaning portion 161 contacts the inner wall of the outer drum, and when it is in the second position, the cleaning portion 161 is separated from the inner wall of the outer drum.

[0053] When the cleaning part 161 is in the first position, that is, when the cleaning part 161 contacts the inner wall of the outer cylinder, by controlling the rotation of the inner cylinder 12, the inner cylinder 12 can drive the cleaning part 161 to rotate together, and the cleaning part 161 performs 360° cleaning on the inner wall of the outer cylinder. In particular, for dirt attached to the inner wall surface that is not easily washed away by water flow, the cleaning part 161 directly contacts the inner wall of the outer cylinder and generates friction, so that the cleaning is more thorough.

[0054] The outer cylinder cleaning device 16 can be arranged on the inner cylinder side wall 103 or on the inner cylinder bottom. When the outer cylinder cleaning device 16 is arranged on the inner cylinder side wall 103, it can clean the inner side wall of the outer cylinder as the inner cylinder 12 rotates. When the outer cylinder cleaning device 16 is arranged on the inner cylinder bottom, it can clean the inner side of the outer cylinder bottom as the inner cylinder 12 rotates.

[0055] Of course, the outer cylinder cleaning device 16 may also be respectively provided on the inner cylinder side wall 103 and the inner cylinder bottom, so as to clean the inner surface of the outer cylinder at the same time.

[0056] The driving rod 1621 has a first end and a second end that are opposite to each other.

[0057] In some embodiments, the driving mechanism 162 includes a driving rod 1621, a through portion (not shown in the figure due to angle reasons) is provided on the inner cylinder 12 to guide and cooperate with the driving rod 1621, the cleaning portion 161 is located between the outer cylinder 11 and the inner cylinder 12, and the first end of the driving rod 1621 passes through the through portion and is connected to the cleaning portion 161. The driving mechanism 162 drives the driving rod 1621 to move, and then drives the cleaning portion 161 to move through the driving rod 1621.

[0058] The driving rod 1621 can perform telescopic movement to push the cleaning portion 161 to move to the first position, or return to the second position.

[0059] In some embodiments, the driving mechanism 162 further includes an armature 1622, an electromagnet 1623, an elastic mechanism 1624, and a power module, wherein the armature 1622 is fixed to the second end of the driving rod 1621. The armature 1622 can be attracted by magnetic force, and when the magnetic attraction force is large enough, it can move under the action of the magnetic attraction force.

[0060] The electromagnet 1623 is arranged opposite to the armature 1622. When the electromagnet 1623 is energized, it generates a magnetic attraction force on the armature 1622, and the armature 1622 can move toward the electromagnet. Since the armature 1622 is fixedly connected to the driving rod 1621, the armature 1622 drives the cleaning part 161 to move to the first position through the driving rod 1621, and the cleaning part 161 contacts the inner wall of the outer tube.

[0061] There are only two relationships between the electromagnet 1623 and the armature 1622: magnetic attraction and no magnetic attraction. In order to enable the cleaning part 161 to retreat to the second position and be separated from the inner wall of the outer cylinder when the inner wall of the outer cylinder does not need to be cleaned, an elastic mechanism 1624 is provided, which is connected between the inner wall of the inner cylinder 12 and the armature 1622. When the armature 1622 is not attracted by the magnetic attraction, the elastic mechanism 1624 is used to support the armature 1622, so that the cleaning part 161 remains in the second position. When the electromagnet 1623 is energized, it generates a magnetic attraction on the armature 1622, and the armature 1622 compresses the elastic mechanism 1624 to move toward the electromagnet.

[0062] When the electromagnet 1623 is powered off, the magnetic attraction force on the armature 1622 disappears, the elastic mechanism 1624 is reset, the armature 1622 moves in a direction away from the electromagnet 1623 , and drives the cleaning portion 161 to move to the second position through the driving rod 1621 .

[0063] The washing machine control method includes: receiving a drum cleaning signal to initiate a drum cleaning procedure; Turn on the water inlet and heat the water; Sending a control command to the driving mechanism to drive the cleaning part to move to the first position; Control the inner cylinder to rotate according to the set speed and direction; After cleaning is completed, a control command is sent to the driving mechanism to drive the cleaning part to move to the second position.

[0064] In some embodiments, the washing machine control method further includes a step of detecting turbidity of water, and when the turbidity of water reaches a set limit, the control generates a drum cleaning signal.

[0065] The power module is controlled by the control module to supply power to the electromagnet 1623 or cut off the power supply.

[0066] In some embodiments, the armature 1622 can also be replaced by a permanent magnet. By controlling the polarity of the surface opposite to the permanent magnet when the electromagnet 1623 is energized, a magnetic attraction force can be generated to attract the permanent magnet, thereby driving the cleaning portion 161 to the first position.

[0067] In addition, when a permanent magnet is used, when the cleaning part 161 needs to be reset to the second position, the electromagnet 1623 can also be controlled to have the same surface polarity as that of the permanent magnet when energized, thereby generating a magnetic repulsive force on the permanent magnet to repel it and assist in resetting the cleaning part 161 to the first position.

[0068] In some embodiments, the elastic mechanism 1624 can be implemented by a spring, or by an object with an elastic structure, such as sponge, memory foam, etc.

[0069] When the elastic mechanism 1624 is a spring, it is sleeved on the outside of the driving rod 1621 .

[0070] In some embodiments, the driving mechanism 162 also includes a shell 1625, and the armature 1622, the electromagnet 1623, the elastic mechanism 1624 and the power module are sealed in the shell 1625. A through hole for accommodating the driving rod 1621 to pass through is opened on the bottom wall of the shell 1625, and a sealing rubber ring is provided in the through hole. The driving rod 1621 fits tightly with the sealing rubber ring, which can prevent water in the outer cylinder from entering the shell 1625, so as to protect the internal structure from being corroded by water.

[0071] The washing machine further comprises a turbidity detection element, which is arranged in the outer tub 11 and is used to detect the turbidity of water and send it to the main control module.

[0072] The wireless communication module is used to receive control signals from the main control module or the mobile communication module; When the wireless communication module is used to receive the control signal from the mobile communication module, the general control module sends the control signal to the mobile communication module through the cloud server.

[0073] The turbidity of the water detected by the turbidity detection element is used to judge the dirtiness in the barrel, and the working state of the outer barrel cleaning device 16 is controlled accordingly.

[0074] The program setting presets the turbidity value when the outer drum of the washing machine is clean as the initial turbidity value.

[0075] In some embodiments, the outer cylinder cleaning method includes: Get the turbidity of water, which is the measured turbidity value; The measured turbidity value is compared with the initial turbidity value. If the measured turbidity value is greater than the initial turbidity value, the main control module will feedback to the server through the whole machine communication module that the outer cylinder needs to be cleaned, and the server will feedback this information to the user's mobile terminal; The user receives the information and issues a simple cleaning program through the mobile terminal, and the whole machine starts the simple cleaning program; The washing machine is filled with water, and after the water filling is completed, washing and heating are performed. The main control module sends a control start signal to the wireless communication module of the inner cleaning device through the whole machine communication module; The inner cylinder cleaning device receives the control signal, energizes the electromagnet through the power module, attracts the armature, and pushes the driving rod to push the brush out to contact the inner wall of the outer cylinder; The motor drives the inner cylinder to rotate, and the cleaning unit 161 starts to clean the outer cylinder; After high temperature soaking and washing in the cleaning section 161, the washing machine performs the first and second rinses by draining the sewage, and the cleaning section 161 continues to clean the outer drum; After the last rinse, the turbidity sensor detects the turbidity value of the outer drum, and sends a signal to the main control module by controlling the wireless communication module, and compares it with the initial turbidity sensor again. If the detected turbidity value is not greater than the initial turbidity value, the outer drum cleaning is completed; When the cylinder cleaning program is finished, the whole machine communication module transmits the end instruction to the external cylinder cleaning device, and the external cylinder cleaning device controls the power module to cut off the power to the electromagnet, and the armature is reset under the elastic force of the spring.

[0076] If the detected turbidity value is greater than the initial turbidity value, continue to run the rinsing program until the detected turbidity value is no greater than the initial turbidity value.
