Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, and in particular to an automatic detection device for leveling a washing machine. Background Technology

[0002] When installing household front-loading and top-loading washing machines, if the four base feet are not leveled, one or two base feet will not be properly grounded, causing instability during operation. This is especially true during the spin-drying process, where the high-speed rotation of the drum will generate significant forces due to the imbalance, leading to severe vibrations. This not only affects washing performance but may also damage the internal structure or cause the washing machine to shift, disrupting normal use.

[0003] Some existing technologies use multiple sensors, such as accelerometers and tilt sensors, to detect the tilt angle of the washing machine. The controller then calculates and analyzes the collected data. Applying this technology to various types of washing machines would result in higher costs.

[0004] Therefore, there is a need for an automatic leveling detection device that can be integrated inside the washing machine base, automatically detect whether the washing machine base is level, and is low in cost. Utility Model Content

[0005] To overcome the problems existing in related technologies, the purpose of this utility model is to provide an automatic detection device for leveling a washing machine, wherein the device can be integrated inside the washing machine base to automatically detect whether the washing machine base is level, and the cost is low.

[0006] An automatic leveling detection device for a washing machine includes a contact switch device disposed within the cavity of a washing machine base, the washing machine base being elastic; the contact switch device includes a first contact and a second contact distributed along the height direction, the second contact being disposed near the bottom of the washing machine base; the first contact and the second contact are used to approach each other and connect when the washing machine base deforms, in order to detect the leveling state of the washing machine base.

[0007] After installing the contact switch device inside the washing machine's base cavity, place the washing machine's base on the mounting surface, such as the ground. Under the combined action of the washing machine's own weight and the pressure of the ground, the washing machine's base will undergo a compressive deformation towards the center, meaning the two ends of the washing machine's base will compress towards the middle. The first contact moves towards the second contact, and the second contact moves towards the first contact, until the first and second contacts come into contact. At this point, the first and second contacts are connected, forming a detection circuit loop. If the detection circuit detects an electrical signal, it indicates that the first and second contacts are connected, and the washing machine's base has been leveled. If the detection circuit does not detect an electrical signal, it indicates that the first and second contacts are not connected, and the washing machine's base is not leveled. This invention utilizes the washing machine's own weight to compress the washing machine's base. The first and second contacts are located inside the washing machine's base. When the washing machine is leveled, the first and second contacts will come into contact with each other and form a circuit, achieving automatic detection of the base's stress state, thereby simplifying the leveling process and improving the accuracy and convenience of leveling. Meanwhile, the automatic leveling detection device for washing machines of this invention has a low design cost and improves the user experience.

[0008] In a preferred embodiment of this invention, the contact switch device further includes a first bracket and a second bracket. The first bracket is disposed on the side of the first contact away from the second contact, and the second bracket is disposed on the side of the second contact away from the first contact. The first contact is fixedly connected to the first bracket, and the second contact is fixedly connected to the second bracket.

[0009] The first bracket is used to fix the first contact, and the second bracket is used to fix the second contact. The first bracket is installed on one side wall of the cavity of the washing machine base, and the second bracket is installed on the other side wall of the cavity of the washing machine base. The first and second brackets can be parallel plate structures or bracket structures with connectors. The connectors are connected to the support part that connects the first and second contacts, and the connectors are used to strengthen the structural strength of the support part.

[0010] In a preferred embodiment of this invention, the first contact is connected to a first control line, the second contact is connected to a second control line, and the first control line and the second control line are respectively connected to different ports of the controller.

[0011] The first control line is connected to the first detection port of the controller, and the second control line is connected to the second detection port of the controller, so as to connect the first contact and the second contact to the controller respectively.

[0012] In a preferred embodiment of this invention, the first control line is connected to the first bracket, and the second control line is connected to the second bracket.

[0013] The first control line is connected to the first bracket, and the second control line is connected to the second bracket. The two control lines, the two brackets, the two contacts, and the controller together form the loop of the detection circuit. The current flows out from the first detection port of the controller, flows sequentially through the first control line, the first bracket, the first contact, the second contact, the second bracket, and the second control line, and flows to the second detection port of the controller.

[0014] In a preferred embodiment of this invention, the contact switch device further includes a fixing block, which is disposed on the side of the first bracket away from the first contact, and is used to fix the first bracket in the cavity of the washing machine base.

[0015] The fixing block is positioned between the first bracket and the bolt, with its two sides abutting against the first bracket and the bolt, respectively.

[0016] In a preferred embodiment of this invention, the automatic leveling detection device for the washing machine further includes a bolt, which is inserted into the cavity of the washing machine base and connected to the fixing block. The bolt is used to adjust the height of the washing machine base.

[0017] The bolts are used to secure the washing machine's base to the four bottom corners of the washing machine. Inserting the bolts into the base and rotating them clockwise or counterclockwise adjusts the height of the base. The bolts, inserted into the base and abutting against the fixing blocks, provide support for the first bracket.

[0018] In a preferred embodiment of this invention, a locking nut is connected to the side of the bolt near the cavity of the washing machine base, and the locking nut is used to fix the height of the washing machine base.

[0019] Insert the locking nut into the bolt from the side and screw it in until it abuts against the bolt, restricting its vertical movement. This fixes the bolt's height and prevents changes in the washing machine's base height during operation. Unscrew the locking nut to separate it from the bolt, allowing the bolt to move vertically and adjust the washing machine's base height.

[0020] In a preferred embodiment of this invention, there is a gap between the first contact and the second contact, and the width of the gap is adjustable.

[0021] When the washing machine base does not deform, the gap between the first contact and the second contact is at its maximum. As the washing machine base deforms, the first contact and the second contact move closer to each other, and the gap between the first contact and the second contact gradually decreases until the first contact and the second contact make contact and connect the circuit, at which point the gap between the first contact and the second contact is at its minimum.

[0022] In a preferred embodiment of this invention, the second bracket abuts against the side of the cavity of the washing machine base away from the fixing block.

[0023] The second contact is fixed on the second bracket. When the washing machine base deforms, the cavity of the washing machine base is compressed, and the second bracket is squeezed by the side of the washing machine base cavity away from the fixed block. The second bracket moves upward in the height direction.

[0024] In a preferred embodiment of this invention, a rubber pad is wrapped around the outside of the washing machine base. The rubber pad is used to reduce the external force on the washing machine base when the washing machine is placed.

[0025] Rubber pads offer excellent shock absorption and anti-slip properties. They also possess sufficient elasticity and wear resistance to adapt to various floor conditions. Utilizing these properties, rubber pads not only dampen the washing machine during high-speed operation but also reduce its impact on the floor, preventing long-term vibration from causing the washing machine's feet to loosen or the machine itself to shift.

[0026] The beneficial effects of this utility model are as follows:

[0027] This invention provides an automatic detection device for leveling a washing machine, including a contact switch device disposed within the cavity of the washing machine's base. The washing machine base is elastic. The contact switch device includes a first contact and a second contact distributed along the height direction, with the second contact positioned near the bottom of the washing machine base. The first and second contacts are used to approach and connect with each other when the washing machine base deforms, thereby detecting the leveling state of the washing machine base. After installing the contact switch device within the cavity of the washing machine base, the washing machine base is placed on a mounting surface, such as the ground. Under the combined action of the washing machine's own weight and the pressure of the ground, the washing machine base undergoes a compressive deformation towards the center, i.e., the two ends of the washing machine base compress towards the middle. The first contact moves towards the second contact, and the second contact moves towards the first contact, until the first and second contacts abut against each other. At this point, the first and second contacts are connected, forming a detection circuit loop. If the detection circuit detects an electrical signal, it indicates that the first and second contacts have connected, and the washing machine base has been leveled. If the detection circuit does not detect an electrical signal, it indicates that the first and second contacts are not connected, and the washing machine's feet are not leveled. This invention utilizes the washing machine's own weight to compress its feet. First and second contacts are installed inside the feet. When the washing machine is leveled, these contacts abut against each other, forming a circuit, automatically detecting the force applied to the feet. This simplifies the leveling process and improves accuracy and convenience. Furthermore, the automatic leveling detection device of this invention has a low design cost, enhancing the user experience. Attached Figure Description

[0031] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0032] Example 1

[0033] like Figure 1 As shown, this embodiment provides an automatic detection device for leveling a washing machine, including a contact switch device disposed within the cavity 2 of a washing machine base 1, the washing machine base 1 being elastic; the contact switch device includes a first contact 3 and a second contact 4 distributed along the height direction, the second contact 4 being disposed near the bottom of the washing machine base 1; the first contact 3 and the second contact 4 are used to approach each other and connect when the washing machine base 1 is deformed, so as to detect the leveling state of the washing machine base 1.

[0034] The washing machine base 1 has 2 or 4 feet, and is made of a deformable material. In this embodiment, the washing machine base 1 has 4 feet, and the material of the washing machine base 1 is rubber. When the washing machine base 1 is subjected to force, it will deform, and the first contact 3 and the second contact 4 in the cavity 2 will move relative to each other. The leveling state includes two states, one of which is leveled and the other of which is not leveled.

[0035] First, install the contact switch device in each washing machine base 1. Then, place the washing machine base 1 on the mounting position, such as the ground. Under the combined action of the washing machine's own weight and the reaction force applied by the mounting position, the washing machine base 1 deforms, and the two ends of the washing machine base 1 are compressed towards the middle.

[0036] The first contact 3 is located above the second contact 4. The second contact 4 is located on the side closer to the contact surface between the washing machine base 1 and the mounting position, while the first contact 3 is located on the side farther away from the contact surface between the washing machine base 1 and the mounting position. Under the action of gravity, the first contact 3 moves downward, the washing machine base 1 presses against the mounting position, and the mounting position applies a counterforce to the washing machine base 1, causing the second contact 4 to move upward.

[0037] During the compression process of the washing machine base 1, the first contact 3 moves towards the second contact 4, and the second contact 4 moves towards the first contact 3, that is, the first contact 3 and the second contact 4 move towards each other until they come into contact. Since both the first contact 3 and the second contact 4 are made of conductive material, when the first contact 3 and the second contact 4 come into contact, a detection circuit loop is formed. If the detection circuit detects an electrical signal at the contact switch formed by the first contact 3 and the second contact 4, it indicates that the first contact 3 and the second contact 4 have come into contact, and the corresponding washing machine base 1 has been leveled, that is, the corresponding washing machine base 1 is placed horizontally in the installation position.

[0038] When the first contact 3 and the second contact 4 of each washing machine base 1 are connected, it is determined that all washing machine base 1s are leveled. When the first contact 3 and the second contact 4 of one or more washing machine base 1s are not connected, it is determined that the corresponding washing machine base 1 is not leveled.

[0039] This invention only requires integrating a contact switch device inside the washing machine base 1 to automatically detect whether the washing machine base 1 is level. This invention opens a cavity 2 inside the washing machine base 1, making full use of the internal space of the washing machine base 1. In this embodiment, the first contact 3 and the second contact 4 are both made of metal sheets, which has the advantage of low cost.

[0040] This embodiment provides an automatic leveling detection device for a washing machine, including a contact switch device disposed within the cavity 2 of a washing machine base 1, which is elastic. The contact switch device includes a first contact 3 and a second contact 4 distributed along the height direction, with the second contact 4 positioned near the bottom of the washing machine base 1. The first contact 3 and the second contact 4 are used to approach and connect with each other when the washing machine base 1 deforms, thereby detecting the leveling state of the washing machine base 1. After installing the contact switch device within the cavity 2 of the washing machine base 1, the washing machine base 1 is placed on a mounting surface, such as the ground. Under the combined action of the washing machine's own weight and the pressure of the ground, the washing machine base 1 undergoes a compressive deformation towards the center, i.e., both ends of the washing machine base 1 compress towards the center. The first contact 3 moves towards the second contact 4, and the second contact 4 moves towards the first contact 3, until the first contact 3 and the second contact 4 come into contact, at which point the first contact 3 and the second contact 4 are connected, forming a detection circuit loop. If the detection circuit detects an electrical signal, it indicates that the first contact 3 and the second contact 4 are connected, and the washing machine base 1 has been leveled. If the detection circuit does not detect an electrical signal, it indicates that the first contact 3 and the second contact 4 are not connected, and the washing machine base 1 is not leveled. This invention utilizes the washing machine's own weight to compress the washing machine base 1. The first contact 3 and the second contact 4 are located inside the washing machine base 1. When the washing machine is leveled, the first contact 3 and the second contact 4 will abut against each other and form a circuit, automatically detecting the force state of the base, thus simplifying the leveling process and improving the accuracy and convenience of leveling. At the same time, the automatic leveling detection device of this invention has a low design cost and improves the user experience.

[0041] Example 2

[0042] like Figure 1 As shown, this embodiment provides an automatic leveling detection device for a washing machine, including a contact switch device disposed within the cavity 2 of a washing machine base 1, the washing machine base 1 being elastic; the contact switch device includes a first contact 3 and a second contact 4 distributed along the height direction, the second contact 4 being disposed near the bottom of the washing machine base 1; the first contact 3 and the second contact 4 are used to approach each other and connect when the washing machine base 1 deforms, to detect the leveling state of the washing machine base 1.

[0043] The contact switch device further includes a first bracket 5 and a second bracket 6. The first bracket 5 is disposed on the side of the first contact 3 away from the second contact 4, and the second bracket 6 is disposed on the side of the second contact 4 away from the first contact 3. The first contact 3 is fixedly connected to the first bracket 5, and the second contact 4 is fixedly connected to the second bracket 6.

[0044] The first bracket 5 is used to fix the first contact 3, and the second bracket 6 is used to fix the second contact 4. The first bracket 5 is installed on the side wall of the cavity 2 of the washing machine base 1 on one side, and the second bracket 6 is installed on the side wall of the cavity 2 of the washing machine base 1 on the other side.

[0045] The first bracket 5 and the second bracket 6 can be parallel plate structures or bracket structures with connectors. The connectors are connected to the support part with the first contact point 3 and the second contact point 4 connected. The connectors are used to strengthen the structural strength of the support part.

[0046] The first control line 7 is connected to the first bracket 5, and the second control line 8 is connected to the second bracket 6. The first control line 7 is connected to the first detection port of the controller 9, and the second control line 8 is connected to the second detection port of the controller 9. The first control line 7 is connected to the first bracket 5, and the second control line 8 is connected to the second bracket 6. The two control lines, the two brackets, the two contacts, and the controller 9 together form a detection circuit loop. Current flows out from the first detection port of the controller 9, flows sequentially through the first control line 7, the first bracket 5, the first contact 3, the second contact 4, the second bracket 6, and the second control line 8, and flows to the second detection port of the controller 9.

[0047] The washing machine base 1 has a first lead wire channel and a second lead wire channel, both of which are connected to the cavity 2 inside the washing machine base 1. The first control wire 7 passes through the first lead wire channel and is connected to the first bracket 5, and the second control wire 8 passes through the second lead wire channel and is connected to the second bracket 6.

[0048] The contact switch device in this embodiment further includes a first bracket 5 and a second bracket 6. The first bracket 5 is disposed on the side of the first contact 3 away from the second contact 4, and the second bracket 6 is disposed on the side of the second contact 4 away from the first contact 3. The first contact 3 is fixedly connected to the first bracket 5, and the second contact 4 is fixedly connected to the second bracket 6. The first contact 3 is connected to a first control line 7, and the second contact 4 is connected to a second control line 8. The first control line 7 and the second control line 8 are respectively connected to different ports of the controller 9. Current flows out from the first detection port of the controller 9, flows sequentially through the first control line 7, the first bracket 5, the first contact 3, the second contact 4, the second bracket 6, and the second control line 8, and flows to the second detection port of the controller 9.

[0049] Example 3

[0050] like Figure 1As shown, this embodiment provides an automatic detection device for leveling a washing machine, including a contact switch device disposed within the cavity 2 of a washing machine base 1, the washing machine base 1 being elastic; the contact switch device includes a first contact 3 and a second contact 4 distributed along the height direction, the second contact 4 being disposed near the bottom of the washing machine base 1; the first contact 3 and the second contact 4 are used to approach each other and connect when the washing machine base 1 is deformed, so as to detect the leveling state of the washing machine base 1.

[0051] The contact switch device further includes a first bracket 5 and a second bracket 6. The first bracket 5 is disposed on the side of the first contact 3 away from the second contact 4, and the second bracket 6 is disposed on the side of the second contact 4 away from the first contact 3. The first contact 3 is fixedly connected to the first bracket 5, and the second contact 4 is fixedly connected to the second bracket 6.

[0052] The contact switch device further includes a fixing block 10, which is disposed on the side of the first bracket 5 away from the first contact 3. The fixing block 10 is used to fix the first bracket 5 inside the cavity 2 of the washing machine base 1.

[0053] The automatic leveling detection device for the washing machine also includes a bolt 11, which is inserted into the cavity 2 of the washing machine base 1 and connected to the fixing block 10. The bolt 11 is used to adjust the height of the washing machine base 1.

[0054] A fixing block 10 is positioned between the first bracket 5 and the bolts 11, with both sides of the fixing block 10 abutting against the first bracket 5 and the bolts 11, respectively. The bolts 11 secure the washing machine base 1 to the four bottom corners of the washing machine. Inserting the bolts 11 into the washing machine base 1 and rotating them clockwise or counterclockwise adjusts the height of the washing machine base 1. The bolts 11, inserted into the washing machine base 1 and abutting against the fixing block 10, thus providing support for the first bracket 5.

[0055] A locking nut 12 is connected to the side of the bolt 11 near the cavity 2 of the washing machine base 1. The locking nut 12 is used to fix the height of the washing machine base 1.

[0056] The locking nut 12 is inserted into the bolt 11 from the side. Screwing the locking nut 12 into place causes it to abut against the bolt 11, restricting the bolt 11 from moving vertically. At this point, the height of the bolt 11 is fixed, preventing changes in the height of the washing machine base 1 during operation. Unscrewing the locking nut 12 separates it from the bolt 11, allowing the bolt 11 to move vertically and thus adjust the height of the washing machine base 1.

[0057] The washing machine base 1 in this embodiment is made of rubber material. The rubber base has good shock absorption and anti-slip performance. The rubber material has sufficient elasticity and wear resistance to adapt to different ground conditions.

[0058] The automatic leveling detection device for the washing machine described in this embodiment also includes a bolt 11. The bolt 11 is inserted into the cavity 2 of the washing machine base 1 and connected to the fixing block 10. The bolt 11 is used to adjust the height of the washing machine base 1. A locking nut 12 is connected to the side of the bolt 11 near the cavity 2 of the washing machine base 1. The locking nut 12 is used to fix the height of the washing machine base 1. Insert the bolt 11 into the washing machine base 1, and then rotate the bolt 11 clockwise or counterclockwise to adjust the height of the washing machine base 1. After the height of the washing machine base 1 is adjusted, screw in the locking nut 12 so that the locking nut 12 abuts against the bolt 11, thereby fixing the height of the washing machine base 1. When one or more of the washing machine base 1s are not leveled or are not in contact with the ground, unscrew the locking nut 12 of the corresponding washing machine base 1 so that the locking nut 12 separates from the bolt 11, thereby adjusting the height of the washing machine base 1 until the washing machine base 1 is in contact with the ground.

[0059] Example 4

[0060] like Figure 1 As shown, this embodiment provides an automatic detection device for leveling a washing machine, including a contact switch device disposed within the cavity 2 of a washing machine base 1, the washing machine base 1 being elastic; the contact switch device includes a first contact 3 and a second contact 4 distributed along the height direction, the second contact 4 being disposed near the bottom of the washing machine base 1; the first contact 3 and the second contact 4 are used to approach each other and connect when the washing machine base 1 is deformed, so as to detect the leveling state of the washing machine base 1.

[0061] There is a gap between the first contact 3 and the second contact 4, and the width of the gap is adjustable.

[0062] When the washing machine base 1 is not deformed, the gap between the first contact 3 and the second contact 4 is at its maximum. During the deformation of the washing machine base 1, the first contact 3 and the second contact 4 move closer to each other, and the gap between the first contact 3 and the second contact 4 gradually decreases until the first contact 3 and the second contact 4 contact and connect the circuit, at which point the gap between the first contact 3 and the second contact 4 is at its minimum.

[0063] The second bracket 6 abuts against the side of the cavity 2 of the washing machine base 1 away from the fixing block 10.

[0064] The second contact 4 is fixed to the second bracket 6. When the washing machine base 1 deforms, the cavity 2 of the washing machine base 1 is compressed, and the second bracket 6 is squeezed by the side of the cavity 2 of the washing machine base 1 away from the fixing block 10. The second bracket 6 moves upward in the height direction. Since the second bracket 6 and the second contact 4 are fixedly connected, the second bracket 6 pushes the second contact 4 upward. The second contact 4 is subjected to the upward force of the second bracket 6 until the second contact 4 contacts the first contact 3. Then, the second contact 4 is subjected to the downward force of the first contact 3. At this time, the second contact 4 is subjected to both upward and downward forces, and the upward and downward forces are equal. The forces on the second contact 4 reach equilibrium, and the second contact 4 stops moving.

[0065] The outer side of the washing machine base 1 is covered with a rubber pad 13, which is used to reduce the external force on the washing machine base 1 when the washing machine is placed.

[0066] Rubber pad 13 has excellent shock absorption and anti-slip properties. It also possesses sufficient elasticity and wear resistance to adapt to different floor conditions. Utilizing the excellent properties of rubber pad 13, when the washing machine is running at high speed, it not only provides shock absorption but also reduces the impact of the washing machine on the floor, preventing long-term vibration from causing the washing machine's feet to loosen or the machine body to shift.

[0067] In this embodiment, there is a gap between the first contact 3 and the second contact 4, and the width of the gap is adjustable. The second bracket 6 abuts against the side of the cavity 2 of the washing machine base 1 away from the fixing block 10. A rubber pad 13 is wrapped around the outside of the washing machine base 1, which is used to reduce the external force on the washing machine base 1 when the washing machine is placed. During the deformation of the washing machine base 1, the gap width between the first contact 3 and the second contact 4 gradually decreases until the first contact 3 and the second contact 4 come into contact, at which point the gap width is at its minimum. During the recovery of the deformation of the washing machine base 1, the gap width between the first contact 3 and the second contact 4 gradually increases until the washing machine base 1 returns to its undeformed state, at which point the gap width is at its maximum. As the first contact 3 and the second contact 4 approach each other, the second support 6 experiences an upward force, pushing the second contact 4 upwards until the first contact 3 and the second contact 4 make contact. At this point, the second support 6 experiences a downward force, and the forces on the second support 6 reach equilibrium, causing it to stop pushing the second contact 4 upwards. By wrapping the washing machine's base with rubber pads 13, the washing machine can absorb shock and cushion impacts during high-speed operation or movement, reducing external forces from the ground and significantly extending its lifespan.

[0068] Example 5

[0069] like Figure 2 As shown, this embodiment provides an automatic detection method for washing machine leveling, based on the automatic detection device for washing machine leveling described in any one of embodiments 1-4. The method includes:

[0070] S1: Connect the contact switch device to the controller via the first control line and the second control line.

[0071] S2: Place the washing machine base on the mounting position, which is a horizontal plane.

[0072] S3: Detect whether the controller receives an electrical signal. If so, determine that the washing machine base has been leveled.

[0073] S4: If the controller does not receive an electrical signal, it is determined that the washing machine base is not level.

[0074] During testing, the contact switch device of the washing machine's base 1 is first connected to the controller 9 via the first control line 7 and the second control line 8. Both the first control line 7 and the second control line 8 are wires, and when the contact switch device is in the closed state, the circuit can be made conductive. The controller 9 monitors the state of the contact switch device of the washing machine's base 1 to determine which washing machine base 1 needs adjustment. If insufficient pressure is detected in a certain washing machine base 1, the controller 9 will issue an alarm or prompt the user to make adjustments. For example, the user can be informed which washing machine base 1 needs adjustment by flashing an LED light or displaying a prompt message on the screen.

[0075] Next, place the washing machine's base 1 on the mounting position, which should be a level surface, such as a flat ground. Then, the controller 9 will begin monitoring its operation. When the washing machine is placed on the ground, the controller 9 will detect the status of the contact switches on the base 1. If the contact switches on the base 1 are closed, the controller 9 will receive an electrical signal from the base 1, indicating that the base 1 is under sufficient pressure, and thus the base 1 is considered level. If the contact switches on the base 1 are open, the controller 9 will not receive an electrical signal from the base 1, indicating that the base 1 is not under sufficient pressure, and thus the base 1 is considered unlevel. The user can manually level each base 1 according to the prompts from the controller 9 until the controller 9 receives electrical signals from all bases 1. This indicates that all bases 1 are under balanced pressure, and the controller 9 will then enter normal operating mode, allowing the washing machine to start.

[0076] An automatic detection method for leveling a washing machine according to this embodiment includes connecting the contact switch device to a controller 9 via a first control line 7 and a second control line 8; placing the washing machine base 1 on a mounting position, which is a horizontal plane; detecting whether the controller 9 receives an electrical signal; if so, determining that the washing machine base 1 is leveled; if the controller 9 does not receive an electrical signal, determining that the washing machine base 1 is not leveled. During detection, firstly, the contact switch device of the washing machine base 1 is connected to the controller 9 via the first control line 7 and the second control line 8. The controller 9 has the ability to monitor and adjust the state of the contact switch device and can issue corresponding prompts. Next, the washing machine base 1 is placed on a horizontal surface, and the controller 9 begins to detect the state of the contact switch device of the washing machine base 1. When the controller 9 receives an electrical signal from the washing machine base 1, it can determine that the washing machine base 1 is leveled. When the controller 9 does not receive an electrical signal from the washing machine base 1, it can determine that the washing machine base 1 is not leveled. Users can determine whether the washing machine base 1 is level by checking whether the controller 9 receives an electrical signal. If the washing machine base 1 is not level, the user can manually level it.
