[0076] By adopting the above technical solution, when it is necessary to use the washing machine to wash clothes, first start the power member 300, and the power member 300 drives the movable bracket 200 to move vertically upward, thereby driving the washing machine to move upward until the loading and unloading opening of the washing machine reaches the height required by the user. The user puts the clothes into the washing machine through the loading and unloading opening, and then starts the power member 300 to drive the movable bracket 200 to move downward until the washing machine contacts the horizontal surface through the grounding member 400.

[0077] Start the washing machine. After the washing machine finishes washing, start the power member 300 to drive the movable bracket 200 to move vertically upward until the loading and unloading opening of the washing machine reaches the height required by the user. The user takes the clothes out of the washing machine through the loading and unloading opening, and then start the power member 300 to drive the movable bracket 200 to move downward until the washing machine contacts the horizontal surface through the grounding member 400.

[0078] When the user uses the washing machine, the power member 300 can be used to raise and lower the access opening of the washing machine, so that the height of the access opening can be adjusted to a height that meets the needs of the user, making it convenient for the user to take clothes in and out. In addition, when the washing machine is washing, the washing machine is in contact with the horizontal surface through the grounding member 400, which improves the stability of the washing machine during washing.

[0079] In some embodiments provided in the present application, illustratively, the fixed bracket 100 includes a horizontal frame 110 and a vertical frame 120, the horizontal frame 110 is vertically connected to the vertical frame 120, the horizontal frame 110 is installed on a horizontal plane, and the vertical frame 120 is installed on a vertical plane.

[0080] Exemplarily, both the horizontal frame 110 and the vertical frame 120 are square frames, and the horizontal frame 110 is vertically welded to one side of the vertical frame 120 .

[0081] By adopting the above technical solution, the horizontal frame 110 and the vertical frame 120 form the fixed bracket 100, which improves the stability of the fixed bracket 100 installed on the horizontal plane and the vertical plane, thereby improving the stability of the movable bracket 200 installed on the fixed bracket 100.

[0082] In some embodiments provided in this application, for example, reference Figure 1 and Figure 2 The vertical frame 120 has at least four mounting holes, each of which is evenly distributed on the vertical frame 120 . Bolts 130 are arranged in the mounting holes, and the vertical frame 120 is connected to the vertical surface through the bolts 130 .

[0083] Exemplarily, the vertical frame 120 has four mounting holes, and the four mounting holes are arranged in pairs on both sides of the vertical frame 120 .

[0084] Illustratively, the horizontal frame 110 is placed on a horizontal surface.

[0085] By adopting the above technical solution, the vertical frame 120 is installed on the vertical surface by passing the bolts 130 through the installation holes, thereby ensuring the connection strength between the vertical frame 120 and the vertical surface.

[0086] The horizontal frame 110 is placed on a horizontal plane, ensuring the overall stability of the fixed bracket 100. In the subsequent use process, even if the bolt 130 becomes loose, the horizontal frame 110 will also limit the vertical frame 120, so the fixed bracket 100 will still be stably installed on the vertical plane, ensuring that the fixed bracket 100 still has good stability after long-term use.

[0087] In some embodiments provided in this application, reference is made to Figure 3 and Figure 4 , illustratively, two ends of the movable frame 210 have sliding grooves 211 , and two sides of the vertical frame 120 are at least partially slidably embedded in the sliding grooves 211 .

[0088] By adopting the above technical solution, the movable frame 210 is slidably connected to the vertical frame 120 through the sliding groove 211, thereby improving the stability of the movable frame 210 in the vertical direction.

[0089] In some embodiments provided in this application, for example, reference Figure 1 At least one guide rod 500 is connected to the vertical frame 120 , and the guide rod 500 is arranged along the vertical direction. The movable frame 210 has at least one guide hole, and the guide rod 500 slides through the guide hole.

[0090] Exemplarily, two guide rods 500 are provided, the two guide rods 500 are respectively located on two sides of the movable frame 210 , and the power member 300 is located between the two guide rods 500 .

[0091] By adopting the above technical solution and providing the guide rod 500 , the stability of the movable frame 210 in the vertical direction is improved.

[0092] In some embodiments provided in the present application, illustratively, the power member 300 is a cylinder.

[0093] By adopting the above technical solution, firstly, the principle and structure of the cylinder are simple, easy to install and maintain, and have low requirements for users; secondly, the output force of the cylinder is large, and a fully loaded washing machine can be lifted and lowered; thirdly, the cylinder can be used in high and low temperature environments, and has the ability to be dustproof and waterproof, and can adapt to various harsh environments.

[0094] In some embodiments provided in this application, for example, reference Figure 4 The grounding member 400 includes a grounding rod 410, and the grounding rod 410 is threadedly connected to the through hole 222a.

[0095] The first end 440 and the second end 450 of the grounding member 400 are equivalent to two opposite ends of the grounding rod 410 .

[0096] By adopting the above technical solution, the grounding rod 410 is connected with the horizontal plate 222 through threads, so that the grounding rod 410 can be easily installed on the horizontal plate 222.

[0097] In some embodiments provided in this application, for example, reference Figure 4 The grounding member 400 further includes a nut 420 , which is threadedly connected to the grounding rod 410 , and the nut 420 abuts against the lower end surface of the horizontal plate 222 .

[0098] By adopting the above technical solution, the nut 420 abuts against the lower end surface of the cross plate 222 , so that the nut 420 can provide a supporting force to the cross plate 222 , thereby improving the connection strength between the cross plate 222 and the grounding rod 410 .

[0099] In some embodiments provided in this application, for example, reference Figure 4 The grounding member 400 further includes a pressure relief plate 430 , which is connected to the second end 450 of the grounding rod 410 , and an area of ​​the pressure relief plate 430 is larger than an area of ​​the second end 450 .

[0100] Exemplarily, the pressure relief plate 430 is a disk, wherein the diameter of the disk is greater than the diameter of the ground rod 410 .

[0101] By adopting the above technical solution and providing the pressure relief plate 430, the contact area between the grounding rod 410 and the horizontal plane is increased, thereby reducing the pressure of the grounding rod 410 on the ground, thereby ensuring that the grounding member 400 can well support the washing machine.

[0102] In some embodiments provided in this application, for example, reference Figure 5-Figure 8 The lifting device also includes a detection unit 700 , a controller 800 and an alarm unit 900 , and both the detection unit 700 and the alarm unit 900 are communicatively connected to the controller 800 .

[0103] The detection unit 700 is configured to detect a first offset of the washing machine relative to the mounting frame 220 , and to detect a second offset of the movable bracket 200 relative to the fixed bracket 100 .

[0104] The controller 800 is configured to control the alarm unit 900 to sound an alarm when the first offset is greater than or equal to a first preset value or the second offset is greater than or equal to a second preset value.

[0105] Exemplarily, the detection unit 700 may be a touch switch or an infrared sensor, as long as the detection unit 700 can detect the first offset and the second offset.

[0106] The alarm unit 900 can notify the user through sound, light, app or cloud.

[0107] The first preset value and the second preset value are preferably 2-3 mm.

[0108] By adopting the above technical solution, when the lifting device is started and drives the washing machine to lift in the vertical direction, the detection unit 700 will always detect the first offset. If the first offset is less than the first preset value, it means that the washing machine has no offset during the lifting process or the offset is not enough to affect the normal use of the washing machine, thereby avoiding the subsequent impact on the normal use of the washing machine. If the first offset is greater than or equal to the first preset value, it means that the offset of the washing machine during the lifting process is too large, which will affect the normal use of the washing machine. Therefore, the controller 800 controls the alarm unit 900 to alarm, and the user can repair the lifting device after receiving the alarm information.

[0109] After the lifting device is started, when the washing machine returns to the initial position, the detection unit 700 detects the second offset. If the second offset is less than the second preset value, it means that the washing machine has no offset when it returns to the initial position after lifting or the offset is not enough to affect the normal use of the washing machine, thereby avoiding the subsequent impact on the normal use of the washing machine. If the second offset is greater than or equal to the second preset value, it means that the offset of the washing machine during the lifting process is too large, which will affect the normal use of the washing machine, so the controller 800 controls the alarm unit 900 to alarm, and the user can repair the lifting device after receiving the alarm information.

[0110] In some embodiments provided in this application, for example, reference Figure 6-Figure 8 , the detection unit 700 includes a first detection module 710 and a second detection module 720, the first detection module 710 is installed on at least one of the mounting frame 220 and the washing machine, and the second detection module 720 is installed on the fixing bracket 100;

[0111] The first detection module 710 is configured to detect a first offset;

[0112] The second detection module 720 is configured to detect a second offset.

[0113] Exemplarily, the first detection module 710 includes at least two touch switches or infrared sensors, which are installed on the bottom of the washing machine and one of the mounting racks 220 through a mounting plate, and the touch switches or infrared sensors are located between the mounting rack 220 and the bottom of the washing machine.

[0114] Exemplarily, each touch switch or infrared sensor faces the four corners of the washing machine to improve the accuracy of the detection data of the first detection module.

[0115] The second detection module 720 includes at least two touch switches or infrared sensors. The touch switches or infrared sensors are installed at the bottom of the fixed bracket 100 through a mounting plate and are located at the bottom of the movable bracket 200 .

[0116] Exemplarily, each touch switch or infrared sensor is directly facing the end of the mounting bracket 220 to improve the accuracy of the detection data of the second detection module.

[0117] By adopting the above technical solution, the first detection module 710 is used to detect the first offset, and the second detection module 720 is used to detect the second offset, so that the detection unit 700 can detect the offset of the washing machine during the lifting process or after returning to the initial position.
