[0001] Related Applications

[0002] This application claims the priority of the Chinese invention patent application with patent application number 202310906390.8, application date July 24, 2023, and invention name “Self-moving cleaning machine”. Technical Field

[0003] The present invention relates to the technical field of cleaning equipment, and in particular to a window cleaning machine used for traveling on a non-horizontal plate surface. Background Art

[0004] At present, the cleaning methods for doors and windows at home are to open the windows for cleaning or remove the windows for cleaning. For doors and windows of buildings, cleaning companies use a suspension machine installed outside the building, and use a motor to control the lifting of the suspension frame, and use a brush or water column to clean the doors and windows outside the building. However, the suspension frame is often easily swung by the wind due to the unstable center of gravity. In order to avoid excessive force on the doors and windows, which may cause people to slip or the cleaning equipment to fall and hit people, etc., the doors and windows are only slightly flushed with water, so that the doors and windows cannot be completely cleaned.

[0005] The Chinese invention patent application with publication number CN113928434A discloses a window cleaning machine, which includes a main body, a walking module, an air extraction module and an air pressure sensor. The main body defines a main adsorption space and a second space connected to the main adsorption space. The volume of the second space is smaller than the volume of the main adsorption space, and the second space is closer to the side of the main body than the main adsorption space. The walking module is adjacent to the main body. The air extraction module is arranged on the main body and is connected to the main adsorption space. The air pressure sensor is arranged on the main body and is respectively arranged at one end of the second space. The window cleaning machine is used to walk on the surface of the board. According to the existing technology, when the window cleaning machine is moving and exceeds the edge of the door and window, it can be judged that the suction cup is leaking, and it is judged that it is about to fall due to exceeding the edge of the door and window, so as to stop moving further toward the outer side of the edge of the door and window.

[0006] However, the door and window cleaning robots disclosed in the prior art can only detect the impact of the edge of the door and window by sensing the resistance through the walking module, and the impact of the edge of the door and window may cause the suction cup to lift and leak, making it impossible for the cleaning robot to stably adhere to the surface of the door and window. Therefore, it is necessary to improve the existing cleaning robots so that the cleaning robots can determine whether they have impacted the edge of the door and window or obstacles, and stop moving toward the outer side of the edge of the door and window. Summary of the invention

[0007] The embodiment of the present invention relates to a window cleaning machine, which can clean non-horizontal plate surfaces more cleanly than the door and window cleaning robots in the prior art. In one embodiment, the cleaning robot can solve the technical problem that the cleaning robot cannot stably adhere to the door and window surfaces while cleaning the non-horizontal plate surfaces through the reciprocating motion of the cleaning device.

[0091] [First embodiment]

[0092] Figure 1 A structural exploded view of a window cleaning machine according to an embodiment of the present invention is shown. Figure 2 An exploded view of the bottom plate and carrier plate combination structure of the main body of a window cleaning machine according to an embodiment is shown. Figure 1 and Figure 2 As shown, in one embodiment, the window cleaning machine 10 includes at least one collision structure 17 , a body 11 , a walking module 12 and an exhaust module 13 . Figure 1 In the embodiment, the window cleaning machine 10 includes a plurality of collision structures 17. In addition, the walking modules 12 are arranged on the corresponding two sides of the body 11, and the exhaust modules 13 are all arranged on the body 11. The collision structure 17 is configured so that when the window cleaning machine 10 collides with an obstacle, the collision structure 17 senses the collision from the obstacle, thereby notifying the window cleaning machine 10 to stop moving forward. The window cleaning machine 10 also includes a driving device 16, a first cleaning device 81 and a second cleaning device 82. The window cleaning machine 10 can be a self-propelled cleaning machine.

[0093] Figure 8A cross-sectional view showing a state of a window cleaning machine on a board according to an embodiment. In one embodiment, the window cleaning machine 10 is suitable for being attached to a board 40 (such as Figure 8 As shown in FIG. 1 , the panel 40 is moved on the panel surface 40A by the walking module 12 to clean the dust or stains on the panel surface 40A. In one embodiment, the panel 40 may be a vertical window, a tilted window or a non-horizontal panel. Figure 1 As shown, the walking module 12 may include a walking component 12a and a walking component 12b, which may be a component capable of generating movement such as a pulley or a roller, so as to drive the window cleaning machine to move forward, backward or turn on the plate surface 40A. In the embodiment shown, the walking component 12a and the walking component 12b are pulleys, including a track and two driving wheels driving the track.

[0094] In order to enable the window cleaning machine to move on a non-horizontally placed board 40 without falling, the present invention utilizes the combination of the main body 11 and the exhaust module 13 to achieve the purpose of adsorbing the board surface 40A. Specifically, in one embodiment, the main body 11 includes a carrier plate 120 and a bottom plate 130, and the main body 11 can be formed by stacking the bottom plate 130 and the carrier plate 120 up and down, so that the bottom plate 130 is close to the upper part of the main body 11, and the carrier plate 120 is close to the lower part of the main body 11. In one embodiment, the walking module 12 can be connected to the main body 11, and more specifically, the walking module 12 can be arranged inside the main body 11 or directly against the main body 11. In one embodiment, the collision structure 17 is arranged on the side of the carrier plate 120, and the walking module 12 can be adjacent to both sides of the carrier plate 120. The exhaust module 13 is disposed on the bottom plate 130, and exhausts air from the bottom plate 130 toward the exhaust module 13, so that the air near the board surface 40A is extracted from the board surface 40A, through the first cleaning device 81, the second cleaning device 82, the carrier plate 120 and the bottom plate 130, and then through the exhaust module 13, so that there is a negative pressure between the window cleaning machine 10 and the board surface 40A, so that the atmospheric pressure can generate a force on the window cleaning machine 10, so that the window cleaning machine 10 can be adsorbed on the board surface 40A. In one embodiment, the exhaust module 13 includes a pump.

[0095] In detail, the present invention can realize a negative pressure space between the plate surface 40A, the body 11 and the exhaust module 13, so that the window cleaning machine 10 can move on a non-horizontally placed plate without falling. In one embodiment, the space forming the negative pressure can be further divided into a main adsorption space 550 defined by the body 11, a first subspace 551 and a second subspace 552, and the main adsorption space 550 is connected to the first subspace 551 and the second subspace 552. Specifically, the main adsorption space 550 is formed by the structure of the carrier plate 120 and the bottom plate 130. The first subspace 551 and the second subspace 552 are formed by the structure of the first cleaning device 81 and the second cleaning device 82 and the carrier plate 120.

[0096] In one embodiment, the window cleaning machine 10 also includes an air pressure sensor (not shown) for measuring the air pressure inside the window cleaning machine 10. In one embodiment, the air pressure of the aforementioned main adsorption space 550 is measured. It can measure the state of the negative pressure generated by the aforementioned air extraction through the exhaust module 13. Therefore, when the negative pressure state changes, it can be determined whether the sealing of the aforementioned main adsorption space has changed.

[0097] In one embodiment, the window cleaning machine 10 includes a housing 15, which has a housing space therein for accommodating a collision structure 17, a body 11, a walking module 12, an air extraction module 13, and an air pressure sensor. In one embodiment, the window cleaning machine 10 includes a spraying module 19 that can be embedded in the housing 15, or can be adsorbed or adhered to the housing 15, and the spraying module 19 is used to spray a cleaning liquid such as clean water or a detergent.

[0098] In one embodiment, the carrier 120 is located between the first cleaning device 81 and the bottom plate 130 and between the second cleaning device 82 and the bottom plate 130. The carrier 120 has a first surface 20A (i.e., the upper surface of the carrier 120) and a corresponding second surface 20B (i.e., the lower surface of the carrier 120), and the carrier 120 includes a sealing structure on the first surface 20A for forming a side wall of the main adsorption space 550. In one embodiment, the carrier 120 includes a carrier wall portion 121 on the first surface 20A that protrudes from the first surface 20A and surrounds the main adsorption space 550 (carrier through hole 550b). Preferably, the carrier wall portion 121 is close to the central portion of the carrier 120, and the interior thereof serves as a part of the main adsorption space 550. In one embodiment, the appearance of the carrier 120 has an H-shaped structure similar to the English letter, so the travel component 12a and the travel component 12b are respectively located in the space defined by the H-shaped structure of the carrier 120. Furthermore, in one embodiment, the carrier wall portion 121 may not protrude from the first surface 20A.

[0099] Please refer to Figure 1 In one embodiment, the bottom plate 130 disposed above the carrier 120 has a bottom plate wall portion 131 surrounding the main adsorption space 550 (the first bottom plate through hole 550a), the bottom plate wall portion 131 is close to the central portion of the bottom plate 130, and the bottom plate wall portion 131 is used to engage with the carrier wall portion 121 to form a closed structure, and the bottom plate wall portion 131 can still move relative to the carrier wall portion 121. For example, the bottom plate wall portion 131 can be convex to the side facing away from the carrier 120, and has a corresponding groove 132 (such as Figure 2), allowing the carrier wall 121 to be inserted into the groove 132. The carrier through hole 550b and the first bottom plate through hole 550a form the main adsorption space 550. In one embodiment, the area defined by the carrier wall 121 is the carrier through hole 550b before being sealed, and is the main adsorption space 550 or at least a part thereof after being sealed.

[0100] In one embodiment, the first surface 20A includes a plurality of sensing space walls 122 protruding from the first surface 20A. The sensing space walls 122 are respectively close to the edges of the carrier 120, and the interior thereof is used as a space for sensing air pressure leakage. The window cleaning machine 10 also includes a plurality of air pressure sensors 14. The sensing space walls 122 pass through the second bottom plate through holes 133 (such as the bottom plate 130) of the bottom plate 130. Figure 2 As shown in FIG. 1 , the air pressure sensor 14 is fixed to the sensing space wall 122 to limit the vertical movement of the bottom plate 130 and the carrier plate 120 after they are joined, so that the window cleaning machine 10 can maintain a certain degree of thickness change in the vertical direction without separating the bottom plate 130 and the carrier plate 120. More specifically, as Figure 1 As shown, the bottom plate 130 has a first bottom plate through hole 550a and a plurality of second bottom plate through holes 133 (see Figure 2 ). In one embodiment, the first bottom plate through hole 550a is defined by the bottom plate wall portion 131, for example, the bottom plate wall portion 131 surrounds the first bottom plate through hole 550a. The second bottom plate through hole 133 is opened on the bottom plate 130. In one embodiment, the second bottom plate through hole 133 is close to the edge of the bottom plate 130 and is vertically aligned with the sensing space wall portion 122 of the carrier 120 located below the bottom plate 130. In one embodiment, the inner edge shape of the second bottom plate through hole 133 corresponds to the outer edge shape of the sensing space wall portion 122, for example, the inner edge shape of the second bottom plate through hole 133 is slightly larger than the outer edge shape of the sensing space wall portion 122, so that the sensing space wall portion 122 passes through the second bottom plate through hole 133, and the carrier 120 and the bottom plate 130 can therefore move in the vertical direction along the structure of the sensing space wall portion 122 through the combination of the sensing space wall portion 122 passing through the second bottom plate through hole 133.

[0101] In other modified embodiments, the body 11 may also include at least one pivot shaft (not shown in the figure) to limit the vertical movement of the bottom plate 130 and the carrier plate 120 after they are joined, so that the window cleaning machine can maintain a certain degree of thickness change in the vertical direction without separating the bottom plate 130 and the carrier plate 120. For example, the pivot shaft may be located near a corner of the carrier plate 120, fixed on the suction cup and extending toward the bottom plate 130. The bottom plate 130 is movably connected to the carrier plate 120 through the pivot shaft. During the above-mentioned thickness increase or decrease process of the window cleaning machine, the volume of the main adsorption space 550 is also increased or decreased accordingly. More specifically, in one embodiment, a plurality of through holes are provided on the bottom plate 130, and the pivot shaft passes through the through holes. The length of the pivot shaft is greater than the length of the corresponding through hole, so that the carrier plate 120 can be pivotally connected to the bottom plate 130 through the pivot shaft, and the carrier plate 120 can move along the axis direction of the pivot shaft. Thus, the carrier 120 can move relative to the bottom plate 130 through the pivot axis and can be driven by the bottom plate 130. Preferably, the axis of the pivot axis is substantially parallel to the normal direction of the bottom surface of the carrier 120, so that the carrier 120 can move along the normal direction.

[0102] Figure 3 An exploded view of a carrier plate, a first cleaning device and a second cleaning device of a window cleaning machine according to an embodiment is shown. Figure 3 As shown, in one embodiment, the carrier 120 defines a first through hole 251 and a second through hole 252 that penetrate the carrier 120. Preferably, the first through hole 251 and the second through hole 252 are both located in the area defined by the carrier wall 121; or in the main adsorption space 550.

[0103] The first cleaning device 81 includes a first suction cup 811 and a first cleaning cloth 812. The first suction cup 811 defines a first subspace 551 and is connected to the driving device 16. The first cleaning cloth 812 is disposed on the first suction cup 811, and more specifically, the first cleaning cloth 812 is disposed on the lower surface of the first suction cup 811. A first suction cup wall portion 813 is disposed on the upper surface of the first suction cup 811, and the first suction cup wall portion 813 protrudes toward the carrier 120. Preferably, the first suction cup wall portion 813 protrudes toward the first through hole 251 of the carrier 120 to define the first subspace 551. In one embodiment, the first suction cup wall portion 813 is inserted into the first through hole 251 and can reciprocate in the first through hole 251. In one embodiment, the first suction cup 811 includes a plurality of suction cup openings penetrating the first suction cup 811 and distributed within the range surrounded and defined by the first suction cup wall portion 813. The suction cup openings may be arc-shaped openings, circular openings, slit-shaped openings, long strip-shaped openings, or elliptical openings (e.g., Figure 3 suction cup opening).

[0104] The second cleaning device 82 includes a second suction cup 821 and a second cleaning cloth 822. The second suction cup 821 defines a second subspace 552 and is connected to the driving device 16. The second cleaning cloth 822 is disposed on the second suction cup 821, and more specifically, the second cleaning cloth 822 is disposed on the lower surface of the second suction cup 821. A second suction cup wall portion 823 is disposed on the upper surface of the second suction cup 821, and the second suction cup wall portion 823 protrudes toward the carrier 120. Preferably, the second suction cup wall portion 823 protrudes toward the second through hole 252 of the carrier 120 to define the second subspace 552. In one embodiment, the second suction cup wall portion 823 is inserted into the second through hole 252 and can reciprocate in the second through hole 252. In one embodiment, the second suction cup 821 includes a plurality of suction cup openings penetrating the second suction cup 821 and distributed within the range defined by the second suction cup wall portion 823. The suction cup openings may be arc-shaped openings, circular openings, slit-shaped openings, long strip-shaped openings, or elliptical openings (e.g., Figure 3 suction cup opening).

[0105] Figure 4 A bottom view of a window cleaning machine according to an embodiment is shown. Figure 4 As shown, in one embodiment, the first cleaning cloth 812 and the second cleaning cloth 822 are respectively bonded to the lower surface of the first cleaning device 81 and the second cleaning device 82, and are used to contact the plate surface 40A. In one embodiment, the first cleaning cloth 812 and the second cleaning cloth 822 define a first cloth opening 851 and a second cloth opening 852 respectively to expose the first subspace 551 and the second subspace 552 respectively. In one embodiment, the outer surface of the cleaning cloth has wool fibers for cleaning, and an elastic plastic sheet body is provided inside as its lining structure, so that in addition to the first cloth opening 851 and the second cloth opening 852, the cleaning cloth has a shielding effect that blocks air from passing through. In addition, in one embodiment, the first cleaning cloth 812 and the second cleaning cloth 822 can also cover the first subspace 551 and the second subspace 552 (not shown), respectively, and the first cleaning cloth 812 and the second cleaning cloth 822 are breathable materials.

[0106] In one embodiment, the body 11 defines a main adsorption space 550. The exhaust module 13 is disposed on the body 11, and the exhaust module 13 is connected to the main adsorption space 550. The first cleaning device 81 contacts the plate surface 40A during the cleaning operation, and the second cleaning device 82 contacts the plate surface 40A during the cleaning operation. The driving device 16 is connected to the first cleaning device 81 and the second cleaning device 82, so as to make the first cleaning device 81 and the second cleaning device 82 produce a reciprocating motion, thereby wiping the plate surface 40A back and forth. The first cleaning device 81 defines a first subspace 551. When the first cleaning device 81 contacts the plate surface 40A, the first subspace 551 is connected to the main adsorption space 550, and the main adsorption space 550 is formed into a closed space. The second cleaning device 82 defines a second subspace 552. When the second cleaning device 82 contacts the plate surface 40A, the second subspace 552 is connected to the main adsorption space 550, and the main adsorption space 550 is formed into a closed space.

[0107] In one embodiment, the walking module 12 is located outside the first subspace 551 and the second subspace 552. More specifically, the walking module 12 is located outside the first cleaning device 81 and the second cleaning device 82, and when the first cleaning device 81 and the second cleaning device 82 reciprocate relative to the carrier 120, the walking module 12 does not contact the first cleaning device 81 and the second cleaning device 82. In one embodiment, the first subspace 551 and the second subspace 552 connected to the main adsorption space 550 reciprocate with the reciprocating motion of the first cleaning device 81 and the second cleaning device 82, while maintaining the state of forming the main adsorption space 550 into a closed space. In this embodiment, since the first cleaning device 81 and the second cleaning device 82 reciprocate on the plate surface 40A, the plate 40 can be wiped clean. In addition, due to the reciprocating motion of the first cleaning device 81 and the second cleaning device 82, dynamic friction is formed between the first cleaning device 81 and the second cleaning device 82 and the plate body 40. Since the dynamic friction is less than the static friction, compared with the prior art in which the cleaning device is stationary, the friction of the window cleaning machine 10 moving on the plate body 40 is reduced, and the window cleaning machine 10 can move upward on the plate body 40 more smoothly against gravity. In one embodiment, the window cleaning machine 10 preferably does not include any static cleaning device that contacts and cleans the plate body surface 40A during the cleaning operation and does not move relative to the body 11. Static friction is formed between the static cleaning device and the plate body 40, so that the walking resistance of the window cleaning machine 10 is large, which is not conducive to the window cleaning machine 10 walking on the vertical plate body surface 40A. In another embodiment, the window cleaning machine 10 does not include a static cleaning device, which can further reduce the generation of static friction, and can make the window cleaning machine 10 move upward on the plate body 40 more smoothly against gravity.

[0108] In one embodiment, the driving device 16 causes the first cleaning device 81 to reciprocate in a first direction, and causes the second cleaning device 82 to reciprocate in a second direction, and the first direction is opposite to the second direction. By causing the first cleaning device 81 and the second cleaning device 82 to move in opposite directions at the same time point, the window cleaning machine 10 as a whole can offset the reaction forces of both parties and can move more smoothly on the plate surface 40A.

[0109] In one embodiment, the body 11 further includes a first elastic body 141 and a second elastic body 142. The first elastic body 141 is located between the first suction cup 811 of the first cleaning device 81 and the carrier 120. The first elastic body 141 defines a first through hole 451, and the first suction cup wall portion 813 is inserted into the first through hole 451. In one embodiment, when the first cleaning device 81 is engaged with the carrier 120, the first elastic body 141 is partially compressed, thereby reducing the flow of external air from between the first cleaning device 81 and the carrier 120 into the first sub-space 551 and the main adsorption space 550.

[0110] The second elastic body 142 is located between the second suction cup 821 of the second cleaning device 82 and the carrier 120. The second elastic body 142 defines a second through hole 452, and the second suction cup wall 823 is located in the second through hole 452. In one embodiment, when the second cleaning device 82 is engaged with the carrier 120, the second elastic body 142 is partially compressed to reduce the flow of external air from between the second cleaning device 82 and the carrier 120 into the second sub-space 552 and the main adsorption space 550. In one embodiment, the first elastic body 141 and the second elastic body 142 can be foam respectively.

[0111] As described above, when the present invention is in operation, the air extraction module 13 will draw the air near the plate surface 40A through the first cleaning device 81, the second cleaning device 82, the carrier plate 120 and the bottom plate 130, and then draw it out through the air extraction module 13. In conjunction with the structure disclosed above, in the path of air flowing in the window cleaning machine 10, part of the air actually passes through the first subspace 551 and the second subspace 552 defined by the first cleaning device 81 and the second cleaning device 82, enters the carrier plate opening penetrating the carrier plate 120, and enters the space surrounded by the carrier plate wall portion 121 (e.g., the carrier plate through hole 550b), and then enters the space defined by the bottom plate wall portion 131 (e.g., the first bottom plate through hole 550a) through the bottom plate opening penetrating the bottom plate 130, and then is drawn out by the air extraction module 13 located on the bottom plate 130. In other words, the main adsorption space 550 defined by the main body 11 of one embodiment of the present invention substantially includes a space surrounded and defined by the plate body 40, the carrier wall 121 and the bottom wall 131, and one end of the main adsorption space 550 is covered by the exhaust module 13. The main adsorption space 550 is a first subspace 551 and a second subspace 552 defined by the first cleaning device 81 and the second cleaning device 82 and is closed by the plate body 40. Figure 8 As shown, in one embodiment, the plate surface 40A can serve as one end of a closed main adsorption space 550, and the main adsorption space 550 can have a negative pressure by utilizing the air suction of the air suction module 13 covering the other end of the main adsorption space 550, thereby enabling the window cleaning machine to move on a non-horizontally placed plate 40 without falling.

[0112] like Figure 1 As shown, in one embodiment, the collision structure 17 is configured to be relatively movable on the body 11 or the carrier 120 along the moving direction (F1 or F2) of the window cleaning machine 10. The walking assembly 12b and the walking assembly 12a are track wheels, the long axis of the track wheels extends along the moving direction (F1 or F2), and the collision structure 17 is configured to be relatively movable along the long axis of the walking assembly 12b and the walking assembly 12a. In one embodiment, the window cleaning machine 10 can also solve the problem that the door and window cleaning robot may cause the suction cup to lift and leak due to collision with the edge of the door and window.

[0113] [Second embodiment]

[0114] like Figure 1 and Figure 3As shown, a window cleaning machine 10 provided according to the second embodiment of the present invention has a three-layer structure including a first cleaning device 81, a bottom plate 130 and a carrier plate 120, and the carrier plate 120 is configured to be able to move axially relative to the bottom plate 130. The first cleaning device 81 is configured to perform a planar reciprocating motion relative to the carrier plate 120, and due to this structure, the first cleaning device 81, in addition to the axial movement (up and down movement) in the axial direction D, also includes a planar reciprocating motion (left and right movement) in the first direction F1 or the second direction F2 extending toward both ends of the direction F.

[0115] The window cleaning machine 10 of this embodiment is used to travel on a non-horizontal plate surface 40A. The window cleaning machine 10 can be a self-propelled cleaning machine, which includes a body 11, a walking module 12, an exhaust module 13, a first cleaning device 81 and a driving device 16. The body 11 defines a main adsorption space 550. The walking module 12 is arranged adjacent to the body 11. The exhaust module 13 is arranged on the body 11, and the exhaust module 13 is connected to the main adsorption space 550, so as to make the body 11 adsorb on the plate surface 40A. The first cleaning device 81 contacts the plate surface 40A when performing a cleaning operation. The driving device 16 is connected to the first cleaning device 81 to make the first cleaning device 81 generate a reciprocating motion, thereby wiping the plate surface 40A reciprocatingly. The body 11 also includes a bottom plate 130 and a carrier plate 120. The bottom plate 130 includes a bottom plate wall portion 131 surrounding the first bottom plate through hole 550a. The carrier plate 120 is located between the first cleaning device 81 and the bottom plate 130. The carrier plate 120 and the bottom plate 130 are connected and define the main adsorption space 550 together. The carrier plate 120 is configured to be able to move axially relative to the bottom plate 130. The first cleaning device 81 is configured to perform a planar reciprocating motion relative to the carrier plate 120. (In addition to the up and down movement, it also includes left and right movement.)
