The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] First, a washing machine (not shown) according to an embodiment of the second aspect of the present invention is briefly described. The washing machine includes a housing (not shown) and a foot assembly 100 according to an embodiment of the first aspect of the present invention.

[0037] The washing machine according to the embodiment of the present invention comprises: a housing and a foot assembly 100, wherein the housing comprises a bottom plate, a side plate, a front plate, a rear plate and a top plate, wherein a pair of side plates are fastened to two opposite edges of the bottom plate.

The top plate is fastened to the top edges of the side plate, the front plate and the rear plate. A control panel (not shown) is mounted on the housing for operating the washing machine.

[0038] Although the control panel is mounted on the top plate, the mounting position of the control panel can be changed if necessary. Therefore, the cabinet forms a space for accommodating the main components of the home appliance and protecting them.

[0039] The housing has a washing tub (not shown) for washing clothes and a driving device (not shown) for rotating the washing tub.

Clothes are put into the washing tub through the door body and are washed or dried as the inner drum rotates. At the same time, according to the arrangement of internal components, especially the arrangement of the washing tub, the door body can be installed on the front plate or the top plate. That is, if the washing tub is installed in a horizontal position, the door body is installed on the front plate; if the washing tub is installed in a vertical position, the door body is installed on the top plate.

[0040] According to the washing machine of the embodiment of the present invention, by setting the base assembly 100 of the first embodiment, the overall performance of the washing machine is improved, the movement of the washing machine due to eccentric dehydration is avoided, thereby avoiding the risk of damaging the faucet, and the structure is simple and the production cost is low.

[0041] Reference below Figure 1-Figure 7 A foot assembly 100 according to an embodiment of a first aspect of the present invention is described.

[0042] like Figure 1-Figure 7 As shown, the foot assembly 100 according to the first embodiment of the present invention includes: an anti-slip component 1 and a sealing component 2.

[0043] Specifically, the anti-slip part 1 has an adsorption chamber 11 and a sealing channel 12. The adsorption chamber 11 is formed at the bottom of the anti-slip part 1. A sealing port 111 is formed on the top wall of the adsorption chamber 11. One end of the sealing channel 12 is connected to the sealing port 111 and the other end is connected to the atmosphere. The seal 2 is switchably arranged at the sealing port 111 between a sealed state and a relaxed state. When the seal 2 is in the sealed state, the seal 2 seals the sealing port 111. When the seal 2 is in the relaxed state, there is a gap between the outer peripheral wall of the seal 2 and the inner peripheral wall of the sealing port 111.

[0044] That is, the foot assembly 100 has an anti-slip member 1 and a sealing member 2, the adsorption chamber 11 and the sealing channel 12 are both formed on the anti-slip member 1, the adsorption chamber 11 is formed at the bottom of the anti-slip member 1, the adsorption chamber 11 is formed with a sealing opening 111, the sealing opening 111 is formed at the top of the upper wall of the adsorption chamber 11, and one end of the sealing channel 12 (such as Figure 4 The lower end of the sealing channel 12 shown in FIG. 1 is connected to the sealing port 111, and the other end of the sealing channel 12 (as shown in FIG. Figure 4 The upper end of the sealing channel 12 is connected to the atmosphere, and the sealing opening 111 is also connected to the atmosphere. Thus, the structural design of the anti-slip member 1 is ingenious.

[0045] The seal 2 has two states: a sealing state and a relaxed state, and the seal 2 can switch between the sealing state and the relaxed state. The seal 2 is arranged at the sealing opening 111. When the seal 2 switches from the relaxed state to the sealing state, the seal 2 can seal the sealing opening 111. When the seal 2 switches from the sealing state to the relaxed state, the seal 2 does not seal the sealing opening 111, and there is a gap between the outer peripheral wall of the seal 2 and the inner peripheral wall of the sealing opening 111. Therefore, the design of the seal 2 is ingenious and easy to use.

[0046] Reference Figure 1-Figure 4 As shown, the anti-slip part 1 is formed in a cylindrical shape, an adsorption chamber 11 is formed at the bottom of the anti-slip part 1, and a mounting groove is formed at the top of the anti-slip part 1. The adsorption chamber 11 is formed in a dome shape with the middle of the top wall arched upward and the peripheral wall extending downward, that is, the cross section of the top wall of the adsorption chamber 11 is arc-shaped. A sealing port 111 is formed at the highest point of the arch of the top wall of the adsorption chamber 11. The sealing port 111 is connected to the lower end of the sealing channel 12. The sealing channel 12 extends up and down in the vertical direction, and the sealing channel 12 passes through the anti-slip part 1 in the up and down direction. The upper end of the sealing channel 12 is connected to the atmosphere. A sealing member 2 is arranged at the position of the sealing port 111. The sealing member 2 has two states: sealing and relaxing. When the sealing member 2 reaches the sealing state, the sealing member 2 is squeezed and the sealing port 111 is completely closed by the sealing member 2. When the sealing member 2 switches from the sealing state to the relaxing state, there is a gap between the sealing port 111 and the sealing member 2.

[0047] When the user uses the foot assembly 100 according to the embodiment of the present invention, the foot assembly 100 is first installed on the washing machine according to the second embodiment of the present invention, and the lower part of the anti-slip member 1 contacts the ground. When the washing machine is placed, one end of the foot assembly 100 is connected to the washing machine, and the end surface of the other end of the foot assembly 100 contacts the ground, that is, Figure 1 The upper end of the foot assembly 100 is connected to the washing machine, and the end surface of the lower end of the foot assembly 100 contacts the ground.

[0048] Before placement, the seal 2 is in a relaxed state, and gas can pass through the sealing port 111. When placed, the seal 2 switches from a relaxed state to a sealed state, and the sealing port 111 is gradually sealed. The amount of gas passing through gradually decreases, and the air in the adsorption chamber 11 is gradually discharged. After placement, the seal 2 is completely switched to a sealed state, and the sealing port 111 is completely blocked by the seal 2, and gas cannot pass through the sealing port 111. At this time, a vacuum chamber is formed in the adsorption chamber 11, and a vacuum is formed between the anti-slip part 1 and the ground, generating adsorption force on the ground. Even if the vibration is too large, the washing machine can be placed stably on the ground, avoiding damage to the water pipes and faucets of the washing machine, and reducing the risk of flooding the floor in the user's home.

[0049] When the washing machine is lifted again, the seal 2 switches from the sealed state to the relaxed state, and the gas gradually enters the adsorption chamber 11 from the sealing port 111, and the adsorption chamber 11 is gradually filled with gas. When the washing machine is fully lifted, the seal 2 is in the relaxed state again, and the adsorption chamber 11 is filled with air and loses its adsorption force on the ground, making it easier to move the washing machine.

[0050] According to the foot assembly 100 of the embodiment of the present invention, an anti-slip part 1 and a seal 2 which can be switched between a sealed state and a relaxed state are provided. When the seal 2 is in a sealed state, the adsorption chamber 11 is in a vacuum state, generating an adsorption force, and can be firmly adsorbed to the ground. When the dehydration eccentricity of the washing machine is large, the movement of the washing machine is prevented, and the movement of the washing machine is prevented from damaging the water inlet pipe and the faucet, thereby reducing the risk of indoor flooding of the user. The overall structure is simple, which is convenient for users to use, and the production difficulty is low, thereby reducing the production cost of the washing machine.

[0051] It should be noted here that when the seal 2 is in a relaxed state, the gap between the outer wall of the seal 2 and the inner wall of the sealing port 111 can be continuous, or the gap between the outer wall of the seal 2 and the inner wall of the sealing port 111 can be discontinuous.

[0052] In some embodiments of the present invention, the seal 2 is a deformable member, and the seal 2 is configured to switch from a relaxed state to a sealed state under the gravity of the object supported above the foot assembly 100. That is, the seal 2 is selected to be a deformable member, and the seal 2 can be deformed. Under pressure, the seal 2 switches from a relaxed state to a sealed state, thereby generating an adsorption force, and can be firmly adsorbed to the ground. When the washing machine has a large dehydration eccentricity, the movement of the washing machine is prevented, and the movement of the washing machine is prevented from damaging the water inlet pipe and the faucet.

[0053] When a user uses the foot assembly 100 of the embodiment of the present invention, taking a washing machine as an example, the foot assembly 100 is first installed on the washing machine, and the lower part of the anti-slip member 1 contacts the ground. When the washing machine is placed, one end of the foot assembly 100 is connected to the washing machine, and the end surface of the other end of the foot assembly 100 contacts the ground. Figure 1 The upper end of the foot assembly 100 is connected to the washing machine, and the end surface of the lower end of the foot assembly 100 contacts the ground.

[0054] Before placement, the seal 2 is in a relaxed state, and gas can pass through the sealing port 111. When placed, the seal 2 switches from a relaxed state to a sealed state, the seal 2 gradually deforms, the sealing port 111 is gradually sealed, the amount of gas passing through is gradually reduced, and the air in the adsorption chamber 11 is gradually discharged. After placement, the seal 2 is completely switched to a sealed state, and the sealing port 111 is completely blocked by the seal 2, and gas cannot pass through the sealing port 111. At this time, a vacuum chamber is formed in the adsorption chamber 11, and a vacuum is formed between the anti-slip part 1 and the ground, generating adsorption force on the ground. Even if the eccentricity is too large, the washing machine can be placed stably on the ground, avoiding damage to the water pipes and faucets of the washing machine, and reducing the risk of flooding the floor in the user's home.

[0055] When the washing machine is lifted again, the seal 2 switches from the sealed state to the relaxed state, the seal 2 gradually deforms, the gas gradually enters the adsorption chamber 11 from the sealing port 111, and the adsorption chamber 11 is gradually filled with gas. When the washing machine is fully lifted, the seal 2 is in the relaxed state again, the adsorption chamber 11 is filled with air, and loses its adsorption force on the ground, making it easier to move the washing machine.

[0056] In some embodiments of the present invention, in the direction from one end of the sealing channel 12 toward the other end, the cross-sectional dimension of the sealing member 2 toward one end of the sealing channel 12 gradually decreases. That is to say, the cross-sectional dimension of the sealing member 2 is not completely the same, and in the direction from the lower end toward the upper end of the sealing channel 12, the cross-sectional dimension of the sealing member 2 toward the upper end of the sealing channel 12 gradually decreases. It can also be understood that the cross-sectional dimension of the sealing member 2 is not completely the same in the direction from the upper end of the sealing member 2 toward the lower end of the sealing member 2, and the cross-sectional dimension of the sealing member 2 gradually increases in the direction from the upper end of the sealing member 2 toward the lower end of the sealing channel 12. As a result, the installation of the sealing member 2 is facilitated, and the assembly difficulty of the foot assembly 100 is reduced.

[0057] Reference Figure 4 As shown, in the direction from the lower end of the sealing channel 12 toward the upper end of the sealing channel 12, the size of the cross section of at least part of the seal 2 is the same, and the size of the cross section of another part of the seal 2 gradually decreases. It can also be understood that the size of the cross section of the seal 2 is the smallest at the end face of the upper end of the seal 2, the size of the cross section of the seal 2 gradually increases downward from the end face of the upper end, stops increasing at the middle of the seal 2, and the size of the cross section of the seal 2 remains unchanged from the middle of the seal 2 toward the lower end of the seal 2 until the end face of the lower end of the seal 2. In this way, the seal 2 has a simple structure, is easy to manufacture, and is easy to assemble.

[0058] Furthermore, the sealing channel 12 extends vertically, that is, Figure 4 As shown, the sealing passage 12 extends vertically in the up-down direction.

[0059] Preferably, the sealing member 2 is formed into a column extending vertically. Figure 6 As shown, the seal 2 is columnar, and the size of the cross section of the seal 2 is not exactly the same in the direction from the upper end of the seal 2 to the lower end of the seal 2 , and the seal 2 gradually increases in the direction toward the lower end of the sealing channel 12 .

[0060] In some embodiments of the present invention, a mounting boss 3 located in the adsorption chamber 11 is formed on the anti-slip member 1, a mounting hole 31 penetrating the mounting boss 3 in the vertical direction is formed in the mounting boss 3, the upper end of the mounting hole 31 is connected to the sealing port 111, the sealing member 2 is arranged in the mounting hole 31, and at least part of the sealing member 2 passes through the sealing port 111 and extends into the sealing channel 12. In other words, a mounting boss 3 is formed on the anti-slip member 1, the mounting boss 3 is formed inside the adsorption chamber 11, a mounting hole 31 is formed in the mounting boss 3, the mounting hole 31 penetrating the mounting boss 3 in the vertical direction, the sealing port 111 is connected to the upper end of the mounting hole 31, and the sealing member 2 can be arranged in the mounting hole 31, the sealing member 2 is arranged inside the mounting hole 31, the sealing member 2 is not completely located in the sealing port 111, part of the sealing member 2 passes through the sealing port 111, and part of the sealing member 2 extends into the sealing channel 12. Therefore, the idea of ​​arranging the mounting boss 3 in the adsorption chamber 11 is ingenious. The mounting boss 3 prevents the adsorption chamber 11 from losing its adsorption force due to excessive vacuum times. The structure is simple and easy to manufacture.

[0061] Reference Figure 4 As shown, the mounting boss 3 is located in the adsorption chamber 11, and the mounting hole 31 is formed inside the mounting boss 3, extending in the vertical direction of the mounting boss 3, and the mounting hole 31 passes through the mounting boss 3, a part of the seal 2 is located in the mounting hole 31, and another part of the seal 2 passes through the sealing port 111 and is located in the sealing channel 12, and the seal 2 is formed into a column extending vertically, and the size of the cross section of the seal 2 is the smallest at the end face of the upper end of the seal 2, which has a guiding effect, and is convenient for the seal 2 to be installed into the sealing channel 12 and the sealing port 111.

[0062] During use, taking a washing machine as an example, when the weight of the washing machine is large, it is placed on the ground, and the seal 2 changes from a relaxed state to a sealed state, the seal 2 is compressed and deformed, the sealing port 111 is gradually sealed, the amount of gas passing through is gradually reduced, and the air in the adsorption chamber 11 is gradually discharged. After being placed, the seal 2 is completely switched to a sealed state, the sealing port 111 is completely blocked by the seal 2, and the gas cannot pass through the sealing port 111. At this time, a vacuum chamber is formed in the adsorption chamber 11, and a vacuum is formed between the anti-slip member 1 and the ground. After multiple adsorptions, the top wall of the adsorption chamber 11 is easily fatigued or damaged. The mounting boss 3 is located in the middle of the adsorption chamber 11, and the mounting boss 3 plays a role in supporting the anti-slip member 1, avoiding the anti-slip member 1 from being damaged or fatigued after multiple uses, and the anti-slip member 1 cannot be used normally, thereby extending the service life of the anti-slip member 1 and improving the product quality of the foot assembly 100.

[0063] Preferably, the mounting boss 3 can be formed by a plurality of mounting pieces 32, and the plurality of mounting pieces 32 are arranged around the central axis of the anti-slip member 1 at intervals. Figure 3 As shown, the mounting boss 3 is formed into a dispersed structure consisting of eight mounting plates 32 evenly spaced around the central axis of the anti-slip member 1. This reduces the weight of the anti-slip member 1, improves the supporting hardness of the mounting boss 3, and has a simple structure and is easy to manufacture.

[0064] In some embodiments of the present invention, the anti-skid member 1 comprises an anti-skid body 13 and an embedded plate 14, wherein the embedded plate 14 is embedded in the anti-skid body 13, and the embedded plate 14 has a plurality of connection holes 142, which are arranged at intervals around the central axis of the anti-skid member 1. That is, the anti-skid member 1 comprises an anti-skid body 13 and an embedded plate 14, wherein the anti-skid body 13 wraps the embedded plate 14 in the anti-skid body 13, and the embedded plate 14 is provided with a plurality of connection holes 142, each of which penetrates the embedded plate 14 in the vertical direction, wherein the thickness of the embedded plate 14 in the vertical direction is less than the thickness of the anti-skid body 13 in the vertical direction, and the plurality of connection holes 142 are arranged at intervals around the axis of the anti-skid member 1. Thus, the structure of the anti-skid member 1 is ingenious, the connection holes 142 reduce the weight of the embedded plate 14, further reduce the weight of the foot assembly 100, and the connection holes 142 enhance the connection strength between the embedded plate 14 and the anti-skid body 13.

[0065] Reference Figure 4As shown, the embedded plate 14 is disposed in the anti-slip body 13, and a connecting hole 142 is formed on the embedded plate 14. There are a plurality of connecting holes 142, and the plurality of connecting holes 142 are evenly spaced around the central main line of the anti-slip body 13. The plurality of connecting holes 142 both increase the connection strength between the anti-slip body 13 and the embedded plate 14 and reduce the weight of the base assembly 100. Taking a washing machine as an example, when the weight of the washing machine is large and it is placed on the ground, the air in the adsorption chamber 11 is gradually discharged. After placement, the seal 2 is completely switched to a sealed state, and the sealing port 111 is completely blocked by the seal 2. Gas cannot pass through the sealing port 111. At this time, a vacuum chamber is formed in the adsorption chamber 11, and a vacuum is formed between the anti-slip part 1 and the ground. After multiple adsorptions, the top wall of the adsorption chamber 11 is prone to fatigue or damage. The mounting boss 3 is located in the middle of the adsorption chamber 11. The mounting boss 3 plays a role in supporting the anti-slip part 1. An embedded plate 14 is arranged in the anti-slip body 13, which can evenly transfer the gravity generated during placement to the anti-slip body 13, so that the anti-slip body 13 is evenly stressed, thereby extending the service life of the anti-slip part 1 and improving the product quality of the base assembly 100.

[0066] Preferably, the anti-skid body 13 is a rubber piece, which has a good anti-skid effect. The embedded plate 14 is a metal piece, which has a high support hardness and is not easily deformed or damaged.

[0067] In some embodiments, the embedded plate 14 is further formed with a vent hole 141, which is connected to the sealing channel 12. Figure 4 As shown, the vent hole 141 is formed at the center of the embedded plate 14, and the diameter of the vent hole 141 is smaller than the diameter of the connecting hole 142. Specifically, the diameter of the vent hole 141 is consistent with the diameter of the sealing channel 12. Therefore, the embedded plate 14 is cleverly designed and simple in structure.

[0068] Combine the following Figure 1-Figure 4 The foot assembly 100 according to a specific embodiment of the present invention is described in detail.

[0069] The base assembly 100 has an anti-slip part 1 and a sealing part 2. The adsorption chamber 11 and the sealing channel 12 are both formed on the anti-slip part 1. The adsorption chamber 11 is formed at the bottom of the anti-slip part 1. The adsorption chamber 11 is formed with a sealing port 111. The sealing port 111 is formed at the top of the upper wall of the adsorption chamber 11. The lower end of the sealing channel 12 is connected to the sealing port 111, and the upper end of the sealing channel 12 is connected to the atmosphere.

[0070] The anti-skid member 1 is provided with a mounting boss 3, which is formed inside the adsorption chamber 11, and a mounting hole 31 is formed inside the mounting boss 3, which penetrates the mounting boss 3 in the vertical direction, and a sealing port 111 is connected to the upper end of the mounting hole 31, and a sealing member 2 can be arranged inside the mounting hole 31, and the sealing member 2 is arranged inside the mounting hole 31, and the sealing member 2 is not completely located inside the sealing port 111, and a part of the sealing member 2 passes through the sealing port 111, and a part of the sealing member 2 extends into the sealing channel 12. The mounting boss 3 is a dispersed structure with eight mounting pieces 32 evenly spaced around the central axis of the anti-skid member 1, so that the weight of the anti-skid member 1 is reduced and the support hardness of the mounting boss 3 is improved.

[0071] The anti-slip part 1 has an anti-slip body 13 and an embedded plate 14. The embedded plate 14 is arranged in the anti-slip body 13. A connecting hole 142 is formed on the embedded plate 14. There are multiple connecting holes 142. The multiple connecting holes 142 are evenly spaced around the central main line of the anti-slip body 13. The multiple connecting holes 142 not only increase the connection strength between the anti-slip body 13 and the embedded plate 14, but also reduce the weight of the base assembly 100.

[0072] The anti-slip part 1 is formed in a cylindrical shape, and an adsorption chamber 11 is formed at the bottom of the anti-slip part 1, and an installation groove is formed at the top of the anti-slip part 1. The adsorption chamber 11 is formed in a dome shape with the middle of the top wall arched upward and the surrounding wall extending downward. A sealing port 111 is formed at the highest point of the arched top wall of the adsorption chamber 11, and the sealing port 111 is connected to the lower end of the sealing channel 12. The sealing channel 12 extends up and down in the vertical direction, and the sealing channel 12 passes through the anti-slip part 1 in the up and down direction. The upper end of the sealing channel 12 is connected to the atmosphere, and a sealing part 2 is arranged at the position of the sealing port 111.

[0073] The seal 2 has two states: a sealing state and a relaxed state, and the seal 2 can switch between the sealing state and the relaxed state. The seal 2 is arranged at the sealing opening 111. When the seal 2 switches from the relaxed state to the sealing state, the seal 2 can seal the sealing opening 111. When the seal 2 switches from the sealing state to the relaxed state, the seal 2 does not seal the sealing opening 111, and there is a gap between the outer peripheral wall of the seal 2 and the inner peripheral wall of the sealing opening 111. Therefore, the design of the seal 2 is ingenious and easy to use.

[0074] When using the base assembly 100 of this embodiment, taking the illustrated washing machine as an example, the seal 2 is in a relaxed state before the washing machine is placed, and gas can pass through the sealing port 111. When placed, the seal 2 switches from a relaxed state to a sealed state, and the seal 2 is deformed, and the sealing port 111 is gradually sealed, and the air in the adsorption chamber 11 is gradually discharged. After placement, the seal 2 is in a sealed state, and the sealing port 111 is completely blocked by the seal 2, and gas cannot pass through the sealing port 111. At this time, a vacuum chamber is formed in the adsorption chamber 11, which generates adsorption force on the ground. Even if the eccentricity is too large, the washing machine can be placed stably on the ground, avoiding the water pipes and faucets of the washing machine from being damaged, and reducing the risk of flooding the floor in the user's home.

[0075] When the washing machine is lifted again, the seal 2 switches from the sealed state to the relaxed state, the seal 2 gradually deforms, the gas gradually enters the adsorption chamber 11 from the sealing port 111, and the adsorption chamber 11 is gradually filled with gas. When the washing machine is fully lifted, the seal 2 is in the relaxed state again, the adsorption chamber 11 is filled with air, and loses its adsorption force on the ground, making it easier to move the washing machine.

[0076] The mounting boss 3 prevents the anti-slip member 1 from failing in adsorption and plays a supporting role; the embedded plate 14 makes the anti-slip member 1 evenly stressed and reduces the damage to the anti-slip member 1.

[0077] Combine the following Figure 1-Figure 7 A foot assembly 100 according to another embodiment of the first aspect of the present invention is described.

[0078] According to the present embodiment, the foot assembly 100 includes: an anti-slip member 1 and a sealing member 2. The adsorption chamber 11 and the sealing channel 12 are both formed on the anti-slip member 1. The adsorption chamber 11 is formed at the bottom of the anti-slip member 1. The adsorption chamber 11 is formed with a sealing port 111. The sealing port 111 is formed at the top of the upper wall of the adsorption chamber 11. The lower end of the sealing channel 12 is connected to the sealing port 111, and the upper end of the sealing channel 12 is connected to the atmosphere. The sealing member 2 has two states: a sealing state and a relaxed state, and the sealing member 2 can switch between the sealing state and the relaxed state. The sealing member 2 is arranged at the sealing port 111. When the sealing member 2 switches from the relaxed state to the sealing state, the sealing member 2 can seal the sealing port 111. When the sealing member 2 switches from the sealed state to the relaxed state, the sealing member 2 does not seal the sealing port 111. There is a gap between the outer peripheral wall of the sealing member 2 and the inner peripheral wall of the sealing port 111.

[0079] Reference Figure 5-Figure 7As shown, the anti-slip part 1 is formed in a cylindrical shape, an adsorption chamber 11 is formed at the bottom of the anti-slip part 1, and a mounting groove is formed at the top of the anti-slip part 1. The adsorption chamber 11 is formed in a dome shape with the middle of the top wall arched upward and the peripheral wall extending downward, that is, the cross section of the top wall of the adsorption chamber 11 is arc-shaped. A sealing port 111 is formed at the highest point of the arch of the top wall of the adsorption chamber 11. The sealing port 111 is connected to the lower end of the sealing channel 12. The sealing channel 12 passes through the anti-slip part 1 in the vertical direction. The upper end of the sealing channel 12 is connected to the atmosphere. A sealing member 2 is arranged at the position of the sealing port 111. The sealing member 2 has two states: sealing and relaxing. When the sealing member 2 reaches the sealing state, the sealing member 2 is squeezed and the sealing port 111 is completely closed by the sealing member 2. When the sealing member 2 switches from the sealing state to the relaxing state, there is a gap between the sealing port 111 and the sealing member 2.

[0080] Furthermore, the foot assembly 100 further includes: a support column 4, the support column 4 is arranged on the anti-slip member 1 and extends upward, and a ventilation channel 41 is formed in the support column 4 and vertically penetrates the support column 4, and the lower end of the ventilation channel 41 is connected to the sealing channel 12. That is, the foot assembly 100 includes the anti-slip member 1, the sealing member 2 and the support column 4, and the lower end of the support column 4 (for example Figure 6 The lower end of the support column 4 shown in the figure is connected to the upper end of the anti-slip member 1, the support column 4 extends upward in the vertical direction, and the ventilation channel 41 is formed in the support column 4, and the ventilation channel 41 passes through the support column 4 up and down in the vertical direction. The lower end of the ventilation channel 41 (for example Figure 6 The lower end of the ventilation channel 41 shown in the figure) and the upper end of the sealing channel 12 (for example Figure 6 The upper end of the sealing channel 12 shown in the figure is connected and communicated, the support column 4 has a simple structure and is easy to install, which reduces the difficulty of assembling the base assembly 100.

[0081] Reference Figure 6 As shown, the support column 4 extends in the vertical direction, and a limiting flange 42 is formed at the lower part of the support column 4, the limiting flange 42 is formed around the support column 4, the lower end of the support column 4 is connected to the upper end of the anti-slip member 1, and a ventilation channel 41 is formed in the support column 4, the ventilation channel 41 penetrates the support column 4 in the up and down directions, the ventilation channel 41 is connected to the sealing channel 12, an air outlet is formed at the lower end of the ventilation channel 41, the ventilation channel 41 is connected to the sealing channel 12 through the air outlet, the diameter of the ventilation channel 41 is consistent with the diameter of the sealing channel 12, which is convenient for gas to pass through, so that the gas flows smoothly.

[0082] Furthermore, the foot assembly 100 further includes: a locking member (not shown in the figure), the locking member cooperates with the support column 4 to lock the support column 4, specifically, an external thread is formed on the outer peripheral wall of the support column 4, a threaded connection hole 142 is formed on the locking member, the locking member is sleeved on the support column 4 and threadedly connected with the support column 4. In other words, the foot assembly 100 includes an anti-slip member 1, a sealing member 2, a support column 4 and a locking member, the locking member can be used to lock the support column 4, the external thread of the outer peripheral wall of the support column 4 can be used to connect the support column 4 with the supported object, and the threaded connection with the supported object can be used to level the supported object with the ground, so that the supported object is placed horizontally, a threaded connection hole 142 is formed on the locking member along the central axis of the locking member, and an internal thread is formed on the inner peripheral wall of the threaded connection hole 142, and when the locking member is sleeved on the support column 4, the locking member and the support column 4 are threadedly connected. Therefore, the locking member is cleverly designed to prevent the foot assembly 100 from being accidentally lost during transportation.

[0083] Take washing machine as an example, refer to Figure 6 As shown, an assembly hole is formed on the housing of the washing machine, the assembly hole is adapted to the upper end of the support column 4, the inner peripheral wall of the assembly hole is formed with an internal thread adapted to the outer peripheral wall of the support column 4, and the inner peripheral wall of the threaded connection hole 142 of the locking member is formed with an internal thread. When the foot assembly 100 is installed on the washing machine, the horizontal position of the washing machine is adjusted, and then the locking member is rotated, and the support column 4 and the assembly hole of the housing cannot produce relative rotation. Therefore, the washing machine is placed stably during use.

[0084] Furthermore, the locking member is also formed with a locking boss, which is formed around the locking body, so as to facilitate the rotation of the locking member when the foot assembly 100 is disassembled and assembled. The locking member has a simple structure and an ingenious design.

[0085] In some embodiments of the present invention, a plurality of protrusions 15 are formed on the outer peripheral wall of the anti-slip member 1, and the plurality of protrusions 15 are arranged at intervals around the central axis of the anti-slip member 1. Figure 7 As shown, protrusions 15 are formed on the outer peripheral wall of the anti-slip part 1, and multiple protrusions 15 are used to facilitate rotation when installing the base assembly 100. In addition, when the anti-slip part 1 is installed, multiple protrusions 15 increase the friction between the installed anti-slip part 1 and the anti-slip part 1 to prevent slipping from the base assembly 100.

[0086] Combine the following Figure 5-Figure 7 Another specific embodiment of the foot assembly 100 will be described in detail.

[0087] The foot assembly 100 includes an anti-slip part 1, a sealing part 2, a support column 4 and a locking part. The adsorption chamber 11 and the sealing channel 12 are both formed on the anti-slip part 1. The adsorption chamber 11 is formed at the bottom of the anti-slip part 1. The adsorption chamber 11 is formed with a sealing port 111. The sealing port 111 is formed at the top of the upper wall of the adsorption chamber 11. The lower end of the sealing channel 12 is connected to the sealing port 111, and the upper end of the sealing channel 12 is connected to the atmosphere. A mounting boss 3 is formed on the anti-slip part 1. The mounting boss 3 is formed inside the adsorption chamber 11. A mounting hole 31 is formed inside the mounting boss 3. The sealing part 2 is arranged inside the mounting hole 31. The sealing part 2 is not completely located in the sealing port 111. Part of the sealing part 2 passes through the sealing port 111, and part of the sealing part 2 extends into the sealing channel 12. The mounting boss 3 is a dispersed structure composed of eight mounting pieces 32 evenly spaced around the central axis of the anti-slip part 1.

[0088] The anti-slip part 1 has an anti-slip body 13 and an embedded plate 14. The embedded plate 14 is arranged in the anti-slip body 13. A connecting hole 142 is formed on the embedded plate 14. There are multiple connecting holes 142. The multiple connecting holes 142 are evenly spaced around the central main line of the anti-slip body 13. The anti-slip part 1 is formed into a cylindrical shape. An adsorption chamber 11 is formed at the bottom of the anti-slip part 1. The cross-section of the top wall of the adsorption chamber 11 is arc-shaped. A sealing port 111 is formed at the highest point of the arch of the top wall of the adsorption chamber 11. The sealing port 111 is connected to the lower end of the sealing channel 12. The sealing channel 12 passes through the anti-slip part 1 in the up and down directions. The upper end of the sealing channel 12 is connected to the atmosphere. A sealing part 2 is arranged at the position of the sealing port 111.

[0089] The seal 2 has two states: a sealed state and a relaxed state, and the seal 2 can switch between the sealed state and the relaxed state. The seal 2 is arranged at the sealing port 111. When the seal 2 switches from the relaxed state to the sealed state, the seal 2 can seal the sealing port 111. When the seal 2 switches from the sealed state to the relaxed state, the seal 2 does not seal the sealing port 111, and there is a gap between the outer peripheral wall of the seal 2 and the inner peripheral wall of the sealing port 111.

[0090] The locking piece is used to lock the support column 4. The external thread on the outer peripheral wall of the support column 4 can be used to connect the support column 4 to the washing machine, and the threaded connection with the supported object can adjust the washing machine to be placed horizontally. The locking piece is formed with a threaded connection hole 142 that passes through the locking piece along the central axis of the locking piece, and the inner peripheral wall of the threaded connection hole 142 is formed with an internal thread. When the locking piece is sleeved on the support column 4, the locking piece and the support column 4 are threadedly connected.

[0091] Taking a washing machine as an example, the washing machine needs to be provided with at least four foot assemblies 100. Before the washing machine is placed, the seal 2 is in a relaxed state, and the gas can pass through the sealing port 111. When placed, the seal 2 switches from a relaxed state to a sealed state, the seal 2 is deformed, the sealing port 111 is gradually sealed, and the air in the adsorption chamber 11 is gradually discharged. After placement, the seal 2 is in a sealed state, and the sealing port 111 is completely blocked by the seal 2, and the gas cannot pass through the sealing port 111. At this time, a vacuum chamber is formed in the adsorption chamber 11. After adjusting the washing machine to a horizontal state, rotate the locking parts on each foot assembly 100 to lock each foot assembly 100 at a height that makes the washing machine in a horizontal state.

[0092] When the washing machine is lifted again, the seal 2 switches from the sealed state to the relaxed state, the seal 2 gradually deforms, and the gas gradually enters the adsorption chamber 11 from the sealing opening 111, and the adsorption chamber 11 is gradually filled with gas. When the washing machine is fully lifted, the seal 2 is in the relaxed state again, and the adsorption chamber 11 is filled with air, losing the adsorption force on the ground, making it easier to move the washing machine. The mounting boss 3 avoids the adsorption failure of the anti-slip member 1 and plays a supporting role; the embedded plate 14 makes the force on the anti-slip member 1 uniform, reducing the damage to the anti-slip member 1.

[0093] When the washing machine is moved or needs to be adjusted in level, the locking member is rotated to allow the foot assembly 100 and the housing to rotate relative to each other. After the level of the washing machine is adjusted, each locking member is tightened again to adjust the washing machine to a horizontal state.
