Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a cleaning device and a leveling control system. Background Technology

[0002] Currently, various devices, including but not limited to household appliances, should be installed in specific orientations. For example, household appliances such as washing machines and dryers should be installed horizontally; otherwise, the center of gravity of the drum will shift during rotation, resulting in vibration, noise, and even accelerated wear of components.

[0003] In existing equipment, bottom leveling is done manually, with different feet adjusted separately. This is difficult due to limited space at the bottom of the equipment, and also results in low adjustment efficiency, often requiring multiple adjustments for different feet. Especially for the rear feet, in some cases, the equipment needs to be placed in the installation location, such as inside a cabinet, before leveling, further compressing the operating space.

This ultimately achieves the lifting of the base plate relative to the lifting component. This allows the operator to adjust the height of the rear of the housing from the front of the housing. This operation is not limited by the space at the bottom of the housing, nor by the space behind the housing and the surrounding space, reducing the difficulty of adjusting the height of the rear of the housing and improving the adjustment efficiency.

As another example, at least one of a, b, or c can represent: a, b, c, a+b, a+c, b+c, a+b+c, where a, b, and c can be single or multiple.

[0051] To illustrate the technical solutions described in this application, the following detailed description is provided in conjunction with specific drawings and embodiments.

[0052] Please see Figure 1 , Figure 2 and Figure 3 As shown, this application embodiment first provides a cleaning device 100, which includes a housing 101 and a foot assembly 5. As... Figure 2 As shown, the housing 101 includes a base plate 102 and a front panel 103, with the front panel 103 connected to the front end of the base plate 102. Figure 4 , Figure 6 and Figure 10 As shown, the base assembly 5 includes a lifting member 51, a first rotating member 52, a transmission assembly 54, and a connecting member 55. The lifting member 51 is slidably connected to the base plate 102 along the height direction Z. The first rotating member 52 engages with the lifting member 51 and is rotatably connected to the base plate 102. The front end of the connecting member 55 is rotatably mounted and passes through the front panel 103, and the rear end of the connecting member 55 is connected to the transmission assembly 54. The transmission assembly 54 also engages with the lifting member 51. The transmission assembly 54 is used to convert the rotation of the connecting member 55 into the rotation of the first rotating member 52, so that the first rotating member 52 drives the lifting member 51 to move vertically relative to the base plate 102. The cleaning device 100 has a specific orientation during use. For ease of understanding and description, the length direction X, depth direction, and height direction Z of the cleaning device 100 are defined here. The height direction Z is the vertical direction. In some embodiments, the depth direction is the front-to-back direction, and the length direction X is the left-to-right direction.

[0053] Thus, the front end of the connector 55 is rotatably mounted and passes through the front panel 103. The front end face of the connector 55 can be exposed from the front of the front panel 103. On the front side of the front panel 103, that is, on the front side of the housing 101, the front end of the rotating connector 55 can drive the first rotating member 52 to rotate relative to the lifting member 51 through the transmission assembly 54. Consequently, the first rotating member 52 can move relative to the lifting member 51 in the height direction Z. The first rotating member 52 further drives the base plate 102 to move relative to the lifting member 51 in the height direction Z, which manifests as the housing 101 moving relative to the lifting member 51 in the height direction Z. Therefore, the housing 101 of the cleaning device 100 can be adjusted in the height direction Z.

[0054] The cleaning device 100 provided in this application embodiment has a base assembly 5 in which a connecting member 55 extending in the front-rear direction and penetrating the front panel 103 drives the transmission assembly 54 and the lifting member 51 to rotate, ultimately achieving the lifting and lowering of the base plate 102 relative to the lifting member 51. This allows the operator to adjust the height of the rear side of the housing 101 from the front side of the housing 101. This operation is not limited by the bottom space of the housing 101, nor by the space behind and around the housing 101, reducing the difficulty of adjusting the height of the rear side of the housing 101 and improving the adjustment efficiency.

[0055] The cleaning equipment 100 has an installation surface during installation and use. The installation surface can be a floor, countertop, desktop, cabinet surface, bracket surface, etc. When the lower end of the lifting component 51 abuts against the installation surface, the lifting component 51 remains stationary relative to the installation surface. The lifting and lowering of the first rotating component 52 and the base plate 102 relative to the lifting component 51 allows the cleaning equipment 100 to be adjusted to the required height and level.

[0056] It should be noted that in this cleaning device 100, multiple foot assemblies 5 can be installed on the base plate 102. For example, multiple foot assemblies 5 can be installed on the left and right sides of the rear end of the base plate 102, or foot assemblies 5 can be installed in the middle of the rear end of the base plate 102.

[0057] In some embodiments of this application, the cleaning device 100 can be any device with height adjustment and leveling requirements on the rear side of the housing 101, including but not limited to washing machines, dryers, washer-dryer combos, shoe washers, dishwashers, and even refrigerators and freezers.

[0058] Next, we will introduce the base assembly 5 in detail.

[0059] like Figure 6 , Figure 7 As shown, in some embodiments of this application, the foot assembly 5 further includes a transmission base 53, which is fixedly connected to the base plate 102, specifically to the upper surface of the base plate 102. A first rotating member 52 is rotatably mounted on the transmission base 53. That is, the transmission base 53 provides a mounting position for the first rotating member 52 to facilitate connection between the first rotating member 52 and the lifting member 51 and the transmission assembly 54.

[0060] In some embodiments of this application, the first rotating member 52 has an internal thread, and the lifting member 51 has an external thread. The first rotating member 52 is sleeved on the lifting member 51 and engages with the lifting member 51 by threads. The transmission assembly 54 is used to drive the first rotating member 52 to rotate around the lifting member 51 and to move along the height direction Z.

[0061] like Figure 6 , Figure 7 , Figure 8 and Figure 10 As shown, in some embodiments of this application, the lifting member 51 includes a support portion 511 and a threaded connection portion 512. The support portion 511 is disposed at one end of the threaded connection portion 512, and the threaded connection portion 512 is slidably connected to the base plate 102 along the height direction Z.

[0062] The threaded connection 512 has an external thread and is used to engage with the internal thread of the first rotating member 52.

[0063] The support portion 511 is used to be mounted on the mounting plane and remains relatively stationary with respect to the mounting plane. In some embodiments, the outer dimensions of the support portion 511 are larger than the outer dimensions of the threaded connection portion 512. The support portion 511 has a large contact area with the mounting plane, which helps to ensure the stability of the lifting member 51 on the mounting plane.

[0064] The front end of connector 55 refers to the forward section of connector 55. The rear end of connector 55 refers to the rearward section of connector 55.

[0065] like Figure 6 , Figure 7 and Figure 10 As shown, in some embodiments of this application, the transmission assembly 54 includes a second rotating member 541 connected to the rear end of the connecting member 55, and a third rotating member 543 meshing with the second rotating member 541. The rotation center axes of the second rotating member 541 and the third rotating member 543 are perpendicular to each other, and the third rotating member 543 is coaxial with and fixedly connected to the first rotating member 52. In this way, the torque of the connecting member 55 can be converted by 90 degrees and transmitted to the first rotating member 52, driving the first rotating member 52 to rotate around the vertically arranged lifting member 51.

[0066] As described above, the first rotating member 52 has an internal thread and is sleeved on and meshes with the lifting member 51. When the connecting member 55 rotates, the second rotating member 541 rotates, which in turn drives the third rotating member 543 to rotate. The third rotating member 543 then drives the first rotating member 52 to rotate. Consequently, while rotating around the lifting member 51, the first rotating member 52 can also move along the axial direction of the lifting member 51, that is, along the height direction Z. Thus, through the cooperation of the second rotating member 541 and the third rotating member 543, the torque of the connecting member 55 is converted 90 degrees in space and transmitted to the first rotating member 52.

[0067] like Figure 6 and Figure 10As shown, in some embodiments of this application, the transmission assembly 54 further includes a first gear 542 and a second gear 544 that are meshed together, a third rotating member 543 that is coaxial with and fixedly connected to the second gear 544, and a first gear 542 that is coaxial with and fixedly connected to the first rotating member 52.

[0068] The purpose of this design is that the transmission ratio between the second rotating member 541 and the third rotating member 543 is limited. If the third rotating member 543 were directly meshed with the first rotating member 52, the transmission ratio between the second rotating member 541 and the first rotating member 52 would also be limited. By designing the number of teeth between the second gear 544 and the first gear 542, the transmission ratio between the second rotating member 541 and the first rotating member 52 can be increased. Thus, within the limited length of the second rotating member 541, the first rotating member 52 can achieve a large displacement along the height direction Z, meeting the height adjustment requirements of the cleaning device 100.

[0069] The third rotating component 543 and the second gear 544 can be a single-piece structure, such as... Figure 10 As shown. In other alternative embodiments, the third rotating member 543 and the second gear 544 can be two structures that are manufactured independently and coaxially connected together.

[0070] The second rotating member 541 and the third rotating member 543 can take various forms. In some optional embodiments, the second rotating member 541 and the third rotating member 543 are worm gear assemblies, for example, the second rotating member 541 is a worm and the third rotating member 543 is a worm wheel. In some optional embodiments, the second rotating member 541 and the third rotating member 543 are bevel gear assemblies, where the second rotating member 541 and the third rotating member 543 are two meshing bevel gears. Optionally, the second rotating member 541 and the third rotating member 543 are spiral bevel gear assemblies, where the second rotating member 541 and the third rotating member 543 are two meshing spiral bevel gears. In many other optional embodiments, the second rotating member 541 and the third rotating member 543 can have more transmission combination forms.

[0071] In some alternative embodiments, the first gear 542 and the first rotating member 52 can be two independently manufactured and fixedly connected components. The purpose of this arrangement is that only external teeth need to be machined on the first gear 542, and only internal threads need to be machined on the first rotating member 52, which can simplify the machining difficulty and cost of the first gear 542 and the first rotating member 52, respectively.

[0072] The first gear 542 and the first rotating member 52 can be fixedly connected together by welding, locking with locking components, or other methods. In some optional embodiments, such as... Figure 6 and Figure 10As shown, at least a portion of the first rotating member 52 is located within the first gear 542, and the first rotating member 52 and the first gear 542 are fixedly connected together by a plurality of locking members. Other methods for fixing the first rotating member 52 and the first gear 542 are also possible. In other alternative embodiments, the first gear 542 and the first rotating member 52 may be an integral structure.

[0073] like Figure 6 , Figure 7 and Figure 10 As shown, in some embodiments of this application, the transmission base 53 includes a first housing 531 and a second housing 532 connected opposite to each other, defining a housing space between the first housing 531 and the second housing 532. The aforementioned transmission assembly 54 and lifting member 51 are both disposed within this housing space. The first housing 531 and the second housing 532 can be arranged opposite each other in any direction. Figure 10 As shown, the first housing 531 and the second housing 532 are joined together along the height direction Z. The threaded connection portion 512 of the lifting member 51 passes through the first housing 531 and the second housing 532. In other alternative embodiments, the first housing 531 and the second housing 532 may be joined together in the depth direction or the width direction Y. The transmission base 53 protects the transmission assembly 54 and the first rotating member 52 within it.

[0074] like Figure 6 and Figure 10 As shown, in some embodiments of this application, the transmission assembly 54 further includes at least one bearing 545. The inner ring of the bearing 545 is fixedly connected to the outer peripheral surface of the first rotating member 52, and the outer ring of the bearing 545 is fixedly connected to the inner wall of the transmission base 53. The inner ring of the bearing 545 rotates and moves up and down synchronously with the first rotating member 52, and the outer ring of the bearing 545 and the transmission base 53 move up and down synchronously with the first rotating member 52. Specifically, the inner ring of the bearing 545 is fixedly connected to the outer peripheral surface of the first gear 542.

[0075] Optionally, the inner ring of bearing 545 is interference-fitted with the outer circumferential surface of the first gear 542.

[0076] Optionally, the outer ring of the bearing 545 is interference-fitted with the inner wall of the transmission base 53.

[0077] like Figure 6 and Figure 10As shown, in some embodiments of this application, the transmission assembly 54 may include at least two bearings 545, which are defined here as a first bearing 5451 and a second bearing 5452, respectively. The first bearing 5451 and the second bearing 5452 are arranged at intervals along the height direction Z to provide rotational support for the first rotating member 52 and the first gear 542 at multiple positions along the height direction Z. The purpose of this arrangement is to provide more balanced and stable rotational support for the first rotating member 52 and the first gear 542, ensuring that the first rotating member 52 and the first gear 542 can always move along the height direction Z without any deviation or other problems.

[0078] In some alternative embodiments, the first bearing 5451 is located above the second bearing 5452. The outer ring of the first bearing 5451 can be interference-fitted with the inner wall of the second housing 532, and the outer ring of the second bearing 5452 can be interference-fitted with the inner wall of the first housing 531.

[0079] like Figure 2 and Figure 8 As shown, in some embodiments of this application, the front panel 103 includes a first plate 1031 and a second plate 1032 spaced apart from front to back. The front end of the connector 55 is rotatably mounted and passes through the first plate 1031 and the second plate 1032. The first plate 1031 and the second plate 1032 are spaced apart by a certain distance. The purpose of this arrangement is that, along the depth direction, that is, the axial direction of the connector 55, the front panel 103 can provide multi-point support for the connector 55, which helps to ensure that the axial direction of the connector 55 coincides with the depth direction, and at the same time, it can also reduce the torsion of the connector 55.

[0080] like Figure 2 and Figure 8 As shown, in some embodiments of this application, the housing 101 further includes a third bushing 105, which passes through and is fixedly connected to the second plate 1032. The front end of the connector 55 passes through the third bushing 105. The purpose of this arrangement is that the third bushing 105 has a certain dimension in the depth direction, which can provide rotational support for a section of the connector 55 and further reduce the torsion of the connector 55.

[0081] like Figure 3 As shown, in some embodiments of this application, the cleaning device 100 further includes a leveling control system 200. The leveling control system 200 is used to control the leveling of the various foot assembly 5. Specifically, the leveling control system 200 is used to control the rotation of the first rotating member 52 in each foot assembly 5.

[0082] like Figure 3 , Figure 5 and Figure 8As shown, the leveling control system 200 includes a leveling drive assembly 6, which is disposed outside the housing 101 and connected to the front end of the connector 55 to drive the connector 55 to rotate. Driving the connector 55 to rotate via the leveling drive assembly 6 saves manual operation and improves operational efficiency.

[0083] In the cleaning equipment 100 and the leveling control system 200, the number of leveling drive components 6 can be one or more. When there is only one leveling drive component 6, each foot component 5 can be adjusted sequentially. To ensure that the height adjustment amount of each foot component 5 is consistent, the action information of each adjustment by the leveling drive component 6 can be recorded. That is, as long as the action information of each adjustment process of the leveling drive component 6 is consistent, the height adjustment amount of each foot component 5 can be kept consistent. When there are multiple leveling drive components 6, at least two leveling drive components 6 can operate simultaneously. As long as the action information of the leveling drive components 6 is consistent, the height adjustment amount of the corresponding foot components 5 can be kept consistent.

[0084] Optionally, the number of leveling drive components 6 is the same as the number of foot components 5, and the leveling drive components 6 and foot components 5 are connected in a one-to-one correspondence. This further improves the leveling efficiency of the foot leveling components and avoids multiple and repeated adjustments of multiple foot components 5.

[0085] In some embodiments of this application, such as Figure 3 As shown, the leveling control system 200 also includes a controller 9 and a level detector 8. The level detector 8 is connected to the housing 101 and is used to detect the horizontal tilt angle of the base plate 102. The controller 9 is communicatively connected to the level detector 8 and the leveling drive assembly 6, respectively. The controller 9 can receive the horizontal tilt angle information detected by the level detector 8, and the controller 9 is used to control the operation of the leveling drive assembly 6 according to the horizontal tilt angle information of the base plate 102. When the horizontal tilt angle of the base plate 102 is not 0, the controller 9 sends control information to the leveling drive assembly 6 to control the operation of the leveling drive assembly 6, thereby controlling the base plate 102 to move upward until the horizontal tilt angle of the base plate 102 is 0, at which point the controller 9 controls the leveling drive assembly 6 to stop operating.

[0086] Understandably, after the leveling assembly 5 is adjusted, it remains on the base plate 102 of the cleaning device 100, and the leveling drive assembly 6 needs to be disengaged from the front end of the connector 55. During the use of the cleaning device 100, the leveling drive assembly 6 is separated from the housing 101 and the leveling assembly 5.

[0087] like Figure 8 and Figure 9As shown, in some embodiments of this application, the leveling drive assembly 6 includes a support base 61 and a power component 62. The power component 62 is disposed on the support base 61, and the output shaft of the power component 62 is used to connect with the front end of the connector 55 to drive the front end of the connector 55 to rotate.

[0088] In some alternative embodiments of this application, such as Figure 8 and Figure 9 As shown, the leveling drive assembly 6 also includes a drive head 63, which is mounted on the support base 61 and connected to the output shaft of the power component 62. The drive head 63 protrudes relative to the power component 62. The drive head 63 is used for detachable connection to the front end of the aforementioned connector 55. Furthermore, the power component 62 drives the connector 55 to rotate via the drive head 63.

[0089] Based on this, such as Figure 2 and Figure 10 As shown, the front end of the connector 55 is provided with a rearwardly recessed drive groove 550 that is adapted to the drive head 63. When the drive head 63 is located in the drive groove 550, the drive head 63 and the inner wall of the drive groove 550 can form a circumferential fixed connection through a convex-concave fit. Therefore, the power component 62 can drive the drive head 63 to rotate, and the drive head 63 further drives the connector 55 to rotate.

[0090] like Figure 8 and Figure 9 As shown, in some embodiments of this application, the drive head 63 has an outer peripheral surface that tapers toward the connector 55, such as... Figure 2 As shown, the drive slot 550 has a rearwardly tapering inner circumferential surface. The purpose of this design is to create a positioning guide surface between the outer circumferential surface of the drive head 63 and the inner circumferential surface of the drive slot 550, which facilitates rapid alignment between the drive head 63 and the drive slot 550 and improves alignment efficiency.

[0091] In some alternative embodiments, the inner dimensions of the drive head 63 are configured to be slightly smaller than the inner dimensions of the drive slot 550, so as to form a second gap between the drive head 63 and the drive slot 550. This arrangement aims to provide adaptive adjustment space along the height direction Z between the drive head 63 and the drive slot 550. That is, if a height difference exists between the central axis of the drive head 63 and the central axis of the drive slot 550 in the height direction Z, a connection can be formed through the shape and size difference between the outer peripheral surface of the drive head 63 and the inner peripheral surface of the drive slot 550.

[0092] like Figure 2 and Figure 9As shown, in some embodiments of this application, the support base 61 has a first abutting surface 611, which abuts against the front surface of the front panel 103. Thus, through the mutual abutment between the first abutting surface 611 and the front panel 103, the position of the support base 61 in the front-rear direction can be positioned. Simultaneously, this also helps to prevent the generation of interaction forces in the front-rear direction when the drive head 63 connects and engages with the drive slot 550, avoiding deformation of the connecting member 55 and preventing forces from acting on the transmission assembly 54 and affecting the torque transmission to the first rotating member 52. Furthermore, when the drive head 63 rotates the connecting member 55 through the drive slot 550, the second abutting surface 612 provides a reaction force to the second support assembly and the power member 62, ensuring that the power member 62 and the drive head 63 are stably held in place.

[0093] like Figure 2 and Figure 9 As shown, in some embodiments of this application, the support base 61 has a second abutment surface 612, which abuts against the lower surface of the base plate 102. Thus, through the mutual abutment between the second abutment surface 612 and the lower surface of the base plate 102, the position of the support base 61 in the vertical direction can be positioned. This facilitates the alignment and connection between the drive head 63 and the drive slot 550 in the vertical direction, further improving the alignment efficiency of the drive head 63 and the drive slot 550. Simultaneously, the second abutment surface 612 can also provide a reaction force to the second support assembly and the power component 62, ensuring that the power component 62 and the drive head 63 are stably held in place.

[0094] like Figure 2 As shown, in some embodiments of this application, the housing 101 further includes a side plate 104 that connects the front panel 103 and one side of the bottom plate 102 along the width direction Y. Figure 9 As shown, the support base 61 has a third abutment surface 613, and a second abutment surface 612 for abutting against the outer surface of the side plate 104. The purpose of this arrangement is that the mutual contact between the third abutment surface 613 and the side plate 104 allows the support base 61 to be positioned in the left-right direction. This facilitates the alignment and connection between the drive head 63 and the drive slot 550 in the left-right direction, further improving the alignment efficiency between the drive head 63 and the drive slot 550. The third abutment surface 613 can also provide a reaction force to the second support assembly and the power component 62, ensuring that the power component 62 and the drive head 63 are stably held in place.

[0095] Side panel 104 may include a left side panel and / or a right side panel. When the leveling drive assembly 6 located on the left side drives the left rear side foot assembly 5, its third abutment surface 613 may abut against the outer surface of the left side panel. When the leveling drive assembly 6 located on the right side drives the right rear side foot assembly 5, its third abutment surface 613 may abut against the outer surface of the right side panel.

The support base 61 has a third abutting surface 613 and a second abutting surface 612 for abutting the outer surface of the side plate 104.

The support base 61 has a third abutment surface 613, and the second abutment surface 612 for abutting against the outer surface of the side plate 104.

[0106] In some embodiments of this application, the support base 61 has a first abutting surface 611 for abutting the front surface of the front panel 103; the support base 61 has a second abutting surface 612 for abutting the lower surface of the base plate 102; and the housing 101 further includes a side plate 104 connecting the front panel 103 and the base plate 102 along the width direction Y. The support base 61 has a third abutting surface 613, and the second abutting surface 612 for abutting the outer surface of the side plate 104.

[0107] like Figure 8 and Figure 9 As shown, in some embodiments of this application, the support base 61 includes a third base 614 and a fourth base 615 connected to each other; the third base 614 is disposed on the front side of the front panel 103, the first portion 6151 of the fourth base 615 is disposed on the lower side of the base plate 102, and the second portion 6152 of the fourth base 615 is disposed on the outer side of the side plate 104. At least the aforementioned second abutment surface 612 and the aforementioned third abutment surface 613 are formed on the second portion 6152.

[0108] For the first contact surface 611, please refer to Figure 2 and Figure 8 As shown, in some embodiments of this application, the front surface of the front panel 103 includes a first front surface 1033 and a second front surface 1034, the second front surface 1034 being located below and behind the first front surface 1033; the front end of the connector 55 passes through the first front surface 1033; the first abutting surface 611 is provided on the fourth seat 615 and is used to abut against the second front surface 1034.

[0109] like Figure 4 and Figure 9 As shown, in some embodiments of this application, the fourth seat 615 is provided with a clearance groove 616 for avoiding the lifting member 51. When the first abutment surface 611 of the support seat 61 abuts against the second front surface 1034, the second abutment surface 612 abuts against the lower surface of the base plate 102, and the third abutment surface 613 abuts against the outer surface of the side plate 104, the inner wall of the clearance groove 616 is spaced apart from and does not contact the outer peripheral surface of the lifting member 51.
