DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0050] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] like Figure 1 In a first aspect of the present invention, a built-in washing machine is provided, comprising: an upper cover assembly 20, an external frame 30 and a washing machine body 40.

[0052] In this embodiment, the washing machine body 40 is provided with an opening at the top, namely, the clothing loading port, and is a combination of various components that can complete various washing tasks, wherein the various components include: a barrel assembly, the barrel assembly includes an inner barrel for placing laundry, and an outer barrel involved in the work; a motor, driving the rotation of the inner and outer barrels to complete various washing tasks; a drainage assembly and a shock-absorbing component.

[0053] Furthermore, the upper cover assembly 20 is installed in the external frame 30, and a telescopic device 10 is provided on the top wall of the external frame 30, one end of which is connected to the top of the upper cover assembly 20, and the other end is connected to the external frame 30, so as to realize the lifting and lowering of the upper cover assembly 20; the washing machine body 40 is arranged in the external frame 30 so as to be able to enter and exit, and the position of the washing machine body 40 in the external frame 30 is located below the upper cover assembly 20.

[0054] Specifically, the washing machine body 40 and the upper cover assembly 20 are separately arranged, and the upper cover assembly 20 is connected to the external frame 30 through the telescopic device 10. When the upper cover assembly 20 needs to work with the washing machine body 40, the washing machine body 40 is moved into the external frame 30 and its position is located below the upper cover assembly 20. The telescopic device 10 pushes the upper cover assembly 20 down and buckles it on the washing machine body 40; when the washing machine body 40 needs to be moved out of the external frame 30, the telescopic device 10 drives the upper cover assembly 20 to rise and leave the washing machine body 40.

[0055] Further, a monitoring device 31 is provided on the rear wall of the external frame 30 for monitoring the distance that the washing machine body 40 moves into or out of the external frame 30;

[0056] A parking device 32 is provided at the bottom of the external frame 30 for parking the washing machine body 40 ; the monitoring device 31 and the parking device 32 are used to ensure that the washing machine body 40 is positioned below the upper cover assembly 20 in the external frame 30 .

[0057] In this embodiment, the monitoring device 31 is an infrared monitoring device.

[0058] Specifically, the washing machine body 40 moves in and out of the external frame 30. When the washing machine body 40 moves out of the external frame 30, the infrared monitoring device monitors the distance between the side of the washing machine body 40 near the infrared monitoring device and the infrared monitoring device, that is, the distance from the rear wall of the washing machine body 40 to the monitoring device 31; if the first preset distance is reached, the parking device 32 pops up to park the washing machine body 40; when the washing machine body 40 moves into the external frame 30, the infrared monitoring device monitors the distance between the side of the washing machine body 40 near the infrared monitoring device and the infrared monitoring device, that is, the distance from the rear wall of the washing machine body 40 to the monitoring device 31; if the second preset distance is reached, the parking device 32 pops up to park the washing machine body 40.

[0059] It should be noted that the parking device 32 is retracted when the washing machine body 40 is moved into or out of the external frame 30, and will pop up from the retracted position only when the washing machine body 40 needs to be parked.

[0060] In this embodiment, the distance that the washing machine body 40 moves out of or into the external frame 30 is monitored by the monitoring device 31, and the washing machine body 40 is parked by the parking device 32, so as to ensure that the distance when the washing machine body 40 moves out of the external frame 30 is not too far, or that the washing machine body 40 does not collide when moving into the external frame 30, and ensure that the position where the washing machine body 40 moves into the external frame 30 and parks is located below the upper cover assembly 20.

[0061] Furthermore, casters 41 are provided at the bottom of the washing machine body 40 , and the washing machine body 40 can be moved into or out of the external frame 30 by rotating the casters 41 .

[0062] Specifically, casters 41 are provided at the bottom of the washing machine body 40, and the washing machine body 40 is driven to move inside and outside the external frame 30 by the rotation of the casters 41. When the washing machine body 40 needs to be moved out of the external frame 30, the casters 41 rotate to drive the washing machine body 40 to move outside the external frame 30; when the washing machine needs to be returned to the external frame 30, the casters 41 rotate to drive the washing machine body 40 to move inside the external frame 30.

[0063] In this embodiment, the parking of the washing machine is achieved by preventing the movement of the caster 41 by the parking device 32 .

[0064] Furthermore, the telescopic device 10 includes: a cam 12, a tension spring assembly 11 and a driving assembly 13. One end of the tension spring assembly 11 is connected to the external frame 30, and the other end is connected to the upper cover assembly 20; the driving assembly 13 drives the cam 12 to rotate, and the cam 12 rotates to apply force to push the upper cover assembly 20 down to the upper 40 of the washing machine body, and at the same time, the tension spring assembly 11 is stretched to store force; the cam 12 rotates to release force, and the upper cover assembly 20 rises and leaves the washing machine body 40 under the action of the restoring force of the tension spring assembly 11.

[0065] It should be noted that the maximum distance from the connection between the rotating shaft of the driving assembly 13 and the cam 12 to the edge of the cam 12 at least ensures that the lowest position of the upper cover assembly 20 can be buckled on the washing machine body 40. At the same time, the shortest distance from the connection between the rotating shaft of the driving assembly 13 and the cam 12 to the edge of the cam 12 ensures that the highest position of the upper cover assembly 20 will not hinder the washing machine body 40 from moving out of or into the external frame 30.

[0066] Specifically, when the upper cover assembly 20 needs to descend and cooperate with the washing machine body 40, the driving assembly 13 drives the cam 12 to rotate. As the cam 12 rotates, the cam 12 applies a downward force to the upper cover assembly 20, and the upper cover assembly 20 descends under the action of the force until it descends onto the washing machine body 40. At the same time, the tension spring assembly 11 is stretched and stores force due to the descent of the upper cover assembly 20; when the upper cover assembly 20 needs to be separated from the washing machine body 40, the driving assembly 13 drives the cam 12 to rotate. As the cam 12 rotates, the pressure applied to the upper cover assembly 20 decreases. At this time, the tension spring assembly 11 begins to contract under the action of the restoring force, and the upper cover assembly 20 rises under the action of the restoring force of the tension spring assembly 11.

[0067] Furthermore, the washing machine body 40 is provided with a clothing loading port, and the clothing loading port is set in a shape that is low inside and high outside, forming a concave area;

[0068] The upper cover assembly 20 is provided with a boss on one side facing the washing machine body 40 , and the size of the boss is the same as the size of the recessed area, so as to enable the upper cover assembly 20 to descend to the upper part of the washing machine body 40 and cover the clothing loading port of the washing machine body 40 .

[0069] Specifically, the clothing loading port of the washing machine body 40 is low inside and high outside, that is, the height of the washing tub is lower than the height of the shell, forming a recessed area, and the upper cover assembly 20 has a boss. When the upper cover assembly 20 cooperates with the washing machine body 40 to work, the upper cover assembly 20 is pushed by the cam 12 to descend to the washing machine body 40, and the boss of the upper cover assembly 20 coincides with the recessed area and seals, ensuring that no water will splash out at the connection between the upper cover assembly 20 and the washing machine body 40 during the operation of the washing machine body 40.

[0070] Furthermore, the upper cover assembly 20 is also provided with a water inlet mechanism, which includes a water channel 21 and a water valve 22 . The water valve 22 is used to control the on-off of the water channel of the water inlet mechanism; the water channel 21 is used to pass water into the washing machine body 40 .

[0071] Specifically, the upper cover assembly 20 is provided with a water inlet mechanism, which includes a water channel 21 and a water valve 22. The water channel 21 includes at least a horizontal section and a bent section. The water valve 22 is arranged at the edge of the upper cover assembly 20. The water channel 21 extends from the water valve 22 to the inner side of the upper cover assembly 20. The horizontal section extends to the middle position of the upper cover assembly 20, and then bends in the direction of the washing machine body 40 to form a bent section. The end of the bent section is at least in the same horizontal plane as the lower end surface of the boss of the upper cover assembly 20.

[0072] Specifically, when the washing machine needs to wash clothes, the water valve 22 on the water inlet mechanism provided in the upper cover assembly 20 is opened, and the water in the tap water pipe enters the water channel 21 through the water inlet pipe 23, and then enters the washing machine body 40. When the water volume reaches the water volume set in the washing program, the water valve 22 on the water inlet mechanism provided in the upper cover assembly 20 is closed, the water supply is stopped, and the washing machine starts to execute the washing program.

[0073] Furthermore, the built-in washing machine also includes: a control unit, which controls the pop-up or retraction of the parking device 32 and the lifting and lowering of the upper cover assembly 20, and is respectively connected to the monitoring device 31, the parking device 32 and the driving assembly 13.

[0074] Specifically, when the washing machine body 40 needs to be moved out of the external frame 30, the control unit sends the acquired signal to the driving component 13, and the driving component 13 drives the cam 12 to rotate. While the cam 12 rotates, the pressure on the upper cover component 20 is reduced, and the upper cover component 20 rises under the action of the restoring force of the tension spring component 11, driving the upper cover component 20 to separate from the washing machine body 40; the control unit controls the parking device 32 provided on the external frame 30 to be retracted to the inside, and the washing machine body 40 is moved out of the external frame 30 driven by the casters 41. During the moving out process, the monitoring component monitors the distance moved by the washing machine body 40 and sends the monitoring result to the control unit. When the monitored distance reaches the preset threshold, the control unit controls the parking device 32 to pop out, so that the casters 41 of the washing machine body 40 stop due to the obstruction of the parking device 32, thereby realizing the parking of the washing machine body 40.

[0075] Specifically, when the washing machine body 40 needs to be moved into the external frame 30, the control unit controls the parking device 32 to be retracted into the interior. During the process of the washing machine body 40 moving into the external frame 30, the monitoring device 31 monitors the distance of the washing machine body 40 moving into the external frame 30, and sends the monitoring result to the control unit. When the monitored distance reaches a preset threshold, the control unit controls the parking device 32 to pop up, so that the casters 41 of the washing machine body 40 stop due to the obstruction of the parking device 32, thereby realizing the parking of the washing machine body 40; then the control unit sends a signal to the driving component 13. After receiving the signal, the driving component 13 drives the cam 12 to rotate. While rotating, the cam 12 applies force to the upper cover component 20. The upper cover component 20 descends under the action of the force. At the same time, the tension spring component 11 extends and accumulates force. The upper cover component 20 descends to the upper part of the washing machine body 40 under the action of the pressure of the cam 12 and fits tightly with the washing machine body 40.

[0076] A second aspect of the present invention provides a control method for an embedded washing machine. Figure 2 and Figure 3 As shown, it includes steps S1 to S4.

[0077] In step S1, an instruction is obtained to control the telescopic device to drive the upper cover assembly to rise;

[0078] In step S2, monitoring the washing machine body to move out of the external frame;

[0079] In step S3, monitoring the washing machine body moving into the external frame;

[0080] In step S4, an instruction is obtained to control the telescopic device to push the upper cover assembly down to cover the upper opening of the washing machine body.

[0081] Optionally, in step S2, the washing machine body is moved out of the external frame, including steps S21 to S22.

[0082] In step S21, the monitoring device monitors the distance L that the washing machine body moves out of the external frame;

[0083] In step S22, if L is greater than or equal to a first preset threshold value L0, the control unit controls the parking device to pop up and the washing machine stops; wherein L0 is the distance that the washing machine body as a whole moves out of the external frame.

[0084] Optionally, in step S3, after the user puts in or takes out the laundry, the washing machine body moves into the external frame, including steps S31 to S32.

[0085] In step S31, the monitoring device monitors the distance L1 that the washing machine body moves into the external frame;

[0086] In step S32, if L1 is less than or equal to a second preset threshold value L2, the control unit controls the parking device to pop up and the washing machine body stops; wherein L2 is the distance between the washing machine body and the rear wall of the external frame when the washing machine body is located below the upper cover assembly.

[0087] Specifically, the user turns on the washing machine through the human-machine interaction interface, the washing machine is powered on and started, the control unit obtains the signal of the washing machine starting, and sends a command to the driving assembly 13. After the driving assembly 13 obtains the command, it drives the cam 12 to rotate. While the cam 12 rotates, the pressure applied to the upper cover assembly 20 decreases, and the upper cover assembly 20 rises under the driving force of the tension spring assembly 11 and separates from the washing machine body 40. The control unit controls the parking device 32 set on the external frame 30 to be retracted to the inside, and the washing machine body 40 moves out of the external frame 30 under the driving of the casters 41; during the process of the washing machine body 40 moving out of the external frame 30, the monitoring assembly monitors the distance L of the washing machine body 40 moving out of the external frame 30. If the distance L is greater than or equal to the first preset threshold value L0, the control unit controls the parking device 32 to pop out, prevent the casters 41 from moving, and realize the parking of the washing machine body 40.

[0088] It should be noted that the distance L that the washing machine body 40 moves out of the external frame 30 is the distance between the side of the washing machine body 40 facing the monitoring device 31 and the monitoring device 31; the first preset threshold value L0 is the distance between the side of the washing machine body 40 facing the monitoring device 31 and the monitoring device 31 after the washing machine body 40 as a whole comes out of the external frame 30; wherein, the monitoring device 31 is arranged on the rear wall of the external frame 30, and the side of the washing machine body 40 facing the monitoring device 31 is the rear wall of the washing machine.

[0089] Specifically, after the user places the laundry, the control unit controls the parking device 32 to retract, and the washing machine body 40 moves into the external frame 30 driven by the casters 41. When the washing machine body 40 returns to the external frame 30, the monitoring device 31 monitors the distance L1 of the washing machine body 40 entering the external frame 30. If the distance L1 is less than or equal to the second preset threshold value L2, the control unit controls the parking device 32 to pop out, prevents the casters 41 from moving, and realizes the parking of the washing machine body 40. At this time, the washing machine body 40 is just below the upper cover assembly 20 in the external frame 30; then the control unit sends an instruction value to the driving component 13. After receiving the instruction, the driving component 13 drives the cam 12 to rotate. During the rotation, the cam 12 applies force to the upper cover assembly 20, and the upper cover assembly 20 descends under the action of the cam 12. At the same time, the tension spring assembly 11 is stretched and stored as the upper cover assembly 20 descends, and the upper cover assembly 20 descends to the washing machine body 40 and fits tightly with the washing machine body 40, and the washing machine enters the working state.

[0090] It should be noted that the distance L1 that the washing machine body 40 moves into the external frame 30 is the distance between the side of the washing machine body 40 facing the monitoring device 31 and the monitoring device 31; the second preset threshold value L2 is the distance between the side of the washing machine body 40 facing the monitoring device 31 and the monitoring device 31 after the washing machine body 40 enters the external frame 30 as a whole.

[0091] Similarly, in this embodiment, the monitoring device 31 is disposed on the rear wall of the external frame 30, and the side of the washing machine body 40 facing the monitoring device 31 is the rear wall of the washing machine.

[0092] Specifically, after the washing machine enters the working state, the water valve 22 provided in the water inlet mechanism of the upper cover assembly 20 is opened, and the tap water enters the water channel 21 of the upper cover assembly 20 through the water inlet pipe 23, and then enters the washing tub of the washing machine body 40. When the water volume reaches the water volume set by the program, the water valve 22 is closed, the water supply is stopped, and the washing machine executes the set program.

[0093] In another embodiment, after the washing machine completes the washing work, the control unit receives a completion signal and transmits a control command to the driving assembly 13. After receiving the command, the driving assembly 13 drives the cam 12 to rotate. While the cam 12 rotates, the force applied to the upper cover assembly 20 decreases, and the upper cover assembly 20 rises under the action of the restoring force of the dynamic tension spring assembly 11 and separates from the washing machine body 40; the control assembly controls the parking device 32 to be retracted, and then the washing machine body 40 is driven by the casters 41 to move out of the external frame 30. In the process of the washing machine body 40 moving out of the external frame 30, the monitoring device 31 monitors the distance L' of the washing machine body 40 out of the external frame 30. When the distance is greater than or equal to the first preset threshold value L0', the control unit controls the parking device 32 to pop out to prevent the casters 41 from moving, thereby achieving the parking of the washing machine body 40. After the washing machine body 40 is parked, the user takes out the laundry from the washing machine body 40.

[0094] It should be noted that the distance L' that the washing machine body 40 moves out of the external frame 30 and the first preset threshold L0' are the same as the distance L that the washing machine body 40 moves out of the external frame 30 and the first preset threshold L0 when the user puts laundry in the washing machine before the washing machine starts working.

[0095] Specifically, after the user takes out the laundry, the control unit controls the parking device 32 to retract, and the washing machine body 40 returns to the external frame 30 driven by the casters 41; in the process of the washing machine body 40 returning to the external frame 30, the monitoring device 31 monitors the distance L1' of the washing machine body 40 entering the external frame 30. If the distance L1' is less than or equal to the second preset threshold value L2', the control unit controls the parking device 32 to pop up to prevent the movement of the casters 41, thereby achieving the parking of the washing machine body 40. At this time, the washing machine body 40 is located below the upper cover assembly 20; then the control unit controls the driving assembly 13 to drive the cam 12 to rotate, and the cam 12 applies force to the upper cover assembly 20 while rotating. The upper cover assembly 20 descends under the action of the force applied by the cam 12, and at the same time, the tension spring assembly 11 is stretched and charged due to the descent of the upper cover assembly 20, and the upper cover assembly 20 descends to the top of the washing machine body 40 and fits tightly on the washing machine body 40.

[0096] It should be noted that after the user takes out the laundry, the distance L1' and the second preset threshold L2' that the washing machine body 40 moves into the external frame 30 are the same as the distance L1 and the second preset threshold L2 when the user places the laundry.

[0097] In this embodiment, a telescopic device 10 is arranged between the upper cover assembly 20 and the external frame 30, which not only ensures the function of the upper cover assembly 20 but also enables the upper cover assembly 20 to realize the lifting function; a monitoring device 31 is arranged to monitor the distance that the washing machine body 40 moves out of or into the external frame 30, and a parking device 32 is arranged to prevent the rotation of the casters 41 arranged on the washing machine body 40, thereby realizing the parking of the washing machine body 40, which not only ensures that the washing machine body 40 does not move too far out of the external frame 30, but also ensures that the washing machine collides during the moving process and is located below the upper cover assembly 20 in the external frame 30.
