Description

Technical Field

[0001] The present invention belongs to the technical field of household washing and cleaning, and particularly relates to a cleaning machine and a cleaning system having the cleaning machine. Background Art

[0002] The cleaning machine is a floor washer, a vacuum cleaner or a sweeper. The cleaning machine sucks a mixture of dust and the like with moisture on the ground into its inner cavity. In order to separate the mixture of dust particles and moisture, a separation structure is usually adopted in the current cleaning machine for separation.

[0003] The current cleaning system, such as the Chinese utility model patent "A Cleaning System" previously applied by the applicant, with the patent number ZL202222268862.5 (the authorized publication number is CN218279490U), discloses a cleaning system, including: a cleaning machine, including a housing, a sewage discharge pipe and a cover plate rotatably arranged at the sewage discharge port of the sewage discharge pipe; a base station, including a base and a sewage guiding pipe. When the cleaning machine is in the accommodation chamber, the sewage guiding pipe is located above the sewage discharge port and is arranged corresponding to the sewage discharge port; a driving mechanism, arranged on the base, with the power output end connected to the sewage guiding pipe, at least used to drive the sewage guiding pipe to move downward to be connected with the sewage discharge port in communication, or move upward to be separated from the sewage discharge port; a transmission mechanism, with the power input end drivingly connected to the driving mechanism and the power output end drivingly connected to the cover plate, used to drive the cover plate to rotate to open the sewage discharge port when the sewage guiding pipe and the sewage discharge port are in a communicating state or close the sewage discharge port when the sewage guiding pipe is separated from the sewage discharge port.

[0004] In the above cleaning system, the opening and closing of the sewage discharge port are usually realized by the rotation of the cover plate. When there are sand or other particles on the bottom surface of the cover plate, the friction between the cover plate and the surface where the sewage discharge port is located is increased. During the rotation of the cover plate, it may hinder the sealing of the entire sewage discharge port; and for fluff (light substances such as cat hair and hair), it will accumulate on the separation structure. In a humid environment such as moisture, it is easy to emit an odor and affect the suction force, etc.

[0005] Therefore, it is necessary to further improve the existing cleaning system. Summary of the Invention

[0006] The first technical problem to be solved by the present invention is, in view of the above-mentioned current situation of the prior art, to provide a cleaning machine that can reliably block the sewage discharge pipe while improving the cleaning ability of the separation structure.

[0007] The second technical problem to be solved by the present invention is to provide a cleaning system having the above cleaning machine.

[0008] The technical solution adopted by the present invention to solve the above first technical problem is: A cleaning machine, including:

[0009] A housing with a storage chamber inside. The storage chamber has an air inlet and an air outlet, and a fixed pipe vertically arranged and communicating with the storage chamber is provided in the storage chamber. The bottom of the fixed pipe has an opening.

[0010] A separation structure is provided in the storage chamber and is at least used to separate dust and liquid.

[0011] It is characterized in that there is a gap between the bottom edge of the fixed pipe and the bottom wall of the storage chamber. The cleaning machine further includes:

[0012] A sewage pipe is located inside the fixed pipe. A baffle is provided at the bottom of the sewage pipe and is located below the fixed pipe. And sewage outlets are provided on the peripheral wall of the sewage pipe above the baffle. The sewage pipe is fixedly connected to the separation structure relatively and is arranged together with the separation structure to be able to move up and down relative to the fixed pipe. Thus, the sewage pipe has the following two states: In the first state, the baffle of the sewage pipe blocks the opening of the fixed pipe, and the sewage outlets are located in the space enclosed by the baffle and the fixed pipe; In the second state, the sewage pipe moves downward until its baffle opens the opening of the fixed pipe, and the sewage outlets communicate with the storage chamber.

[0013] There are various ways to realize the up and down movement of the sewage pipe. It can adopt the form of being actively driven by a driving mechanism, or other ways. Preferably, an activity pipe for pushing the sewage pipe downward is further included. The activity pipe is vertically arranged and located above the sewage pipe and is communicated with the sewage pipe. In this way, the activity pipe is a part of the pipeline, and the garbage flowing out through the sewage pipe continues to be discharged outward through the activity pipe.

[0014] In order to enable the sewage pipe to automatically reset upward, an elastic member that always makes the sewage pipe have an upward movement tendency is further included. The elastic member acts on the sewage pipe.

[0015] There are various structural forms of the elastic member. It can adopt the form of a spring or the form of a reed piece. However, preferably, the elastic member is a spring located inside the fixed pipe and sleeved outside the sewage pipe. The top peripheral edge of the sewage pipe has a flange extending outward. The opening is opened on the bottom wall plate of the fixed pipe. The spring is located between the flange and the bottom wall plate of the fixed pipe.

[0016] In order to facilitate the activity pipe to push the sewage pipe downward, the flange gradually slopes upward from the inside to the outside. When the activity pipe is in the state of pushing the sewage pipe to move downward, the bottom edge of the activity pipe abuts against the flange.

[0017] To achieve the connection between the baffle and the separation structure, the fixed pipe is located on the peripheral side of the separation structure, and the baffle is connected to the separation structure through a connecting rod.

[0018] There are various structural forms of the separation structure. However, preferably, the air outlet is located on the top wall plate of the storage chamber. The separation structure includes an inner ring wall in the shape of a vertical annular wall surrounding the periphery of the air outlet. The inner ring wall forms an air passage communicating with the air outlet, and the first filter holes are distributed on the inner ring wall.

[0019] Specifically, the separation structure further includes an outer ring wall in the shape of a vertical annular wall surrounding the periphery of the inner ring wall and a connecting plate connecting the top edge of the inner ring wall and the top edge of the outer ring wall. The second filter holes are distributed on the outer ring wall, and the connecting rod is connected to the bottom edge of the outer ring wall.

[0020] To scrape the inner ring wall, a horizontally arranged fixing plate is provided in the storage chamber. The fixing plate is located in the air passage, and the outer peripheral edge of the fixing plate is in contact with the inner peripheral wall of the inner ring wall.

[0021] Preferably, the sewage pipe includes a vertically arranged vertical pipe body and an extension wall provided on the bottom wall of the vertical pipe body and extending downward. There are two extension walls arranged at intervals, and the bottom edges of the two extension walls are connected by a flexible connecting wall. The sewage outlet is formed by enclosing the connecting wall, the bottom wall of the vertical pipe body and the two extension walls. The baffle is installed on the connecting wall. In this way, the flexible connecting wall can be compressed. Since there is a large water passing area before compression, when the sewage pipe is continuously pressed down to the bottom wall of the storage chamber, the water passing area will be reduced a lot. When the purified water enters the storage chamber through the sewage pipe, under the combined action of the water pressure and the downward pressure of the vertical pipe body (similar to pressing the water pipe opening by hand for spraying), the water sprays towards the side wall of the storage chamber, and at the same time can clean the separation structure, achieving a good self-cleaning effect of flushing the side wall of the storage chamber and the separation structure.

[0022] Preferably, the connecting wall includes two inclined walls and a transverse wall located between the two inclined walls and connected to both of them. The transverse wall extends along the arrangement direction of the two extension walls in sequence. Each of the two inclined walls gradually inclines away from each other from bottom to top, and the upper end of each inclined wall is connected to the lower end of the corresponding side extension wall.

[0023] To detect the liquid level height in the storage chamber, a detection member for sensing the liquid level height in the storage chamber is provided on the bottom wall of the vertical pipe body in the area other than the extension wall.

[0024] Preferably, the detection member is an electrode contact, and there are two which are arranged at intervals relatively, and the extension wall is located between the two detection members.

[0025] Specifically, the two extension walls are arranged oppositely. In addition, they can also be arranged in a staggered manner.

[0026] In order to realize the installation of the shielding plate, a convex part extending upward is provided at a position adjacent to the center on the upper wall surface of the shielding plate, and a jack for the convex part to be inserted upward is provided at a position adjacent to the center of the connecting wall. In addition, the form that the shielding plate is directly formed on the connecting wall can also be adopted.

[0027] The technical solution adopted by the present invention to solve the above second technical problem is: a cleaning system, including a base and a cleaning machine, the cleaning machine is a floor sweeping robot, with the traveling direction of the cleaning machine as the front, the base has a receiving chamber with an open rear side for the cleaning machine to enter, and is characterized in that: the cleaning machine is the above-mentioned cleaning machine, the movable pipe is a sewage guiding pipe arranged on the base and capable of moving up and down, and in the state where the cleaning machine is located in the receiving chamber, the sewage guiding pipe and the sewage discharge pipe are arranged corresponding to each other. In this way, relying on the sewage guiding pipe of the base itself to push the sewage discharge pipe, there is no need to additionally set a driving mechanism, reducing components, saving space and reducing costs.

[0028] Compared with the prior art, the advantages of the present invention are: in this cleaning machine, the sewage discharge port is located on the peripheral side wall of the sewage discharge pipe, the sewage discharge pipe is fixedly connected to the separation structure relatively, and a shielding plate located below the fixed pipe is arranged at the bottom of the sewage discharge pipe, and the sewage discharge pipe can move up and down relative to the fixed pipe. Then, the shielding plate of the sewage discharge pipe moves upward to block the bottom opening of the fixed pipe. At this time, the sewage discharge port is located in the space enclosed by the shielding plate and the fixed pipe, that is, the sewage discharge pipe is blocked by the upward movement of the sewage discharge pipe, with high reliability and good blocking effect of the shielding plate on the opening of the fixed pipe; when it is necessary to realize the outdoor discharge of garbage in the storage chamber or self-cleaning, by moving the sewage discharge pipe downward, the shielding plate of the sewage discharge pipe opens the opening of the fixed pipe. At this time, the sewage discharge port is communicated with the storage chamber. The whole opening and closing process is simple and reliable, and the problem of affecting the rotation of the cover plate caused by the particles on the shielding plate in the background technology is avoided. And in the process of the separation structure moving downward along with the sewage discharge pipe, the liquid in the storage cavity flushes the separation structure, reducing the accumulation of fluff on the separation structure and realizing the cleaning of the separation structure.

[0035] The present invention will be further described in detail below in conjunction with the embodiments with reference to the drawings.

[0036] As Figure 1 shown, the cleaning system of this embodiment includes a base 7 and a cleaning machine. Among them, the cleaning machine is a floor sweeping robot 8, and the forward direction of the floor sweeping robot is defined as the front. The aforementioned base 7 has a receiving chamber 70 with an open rear side for the floor sweeping robot 8 to enter. A sewage guiding pipe 71 that can move up and down is provided on the above-mentioned base 7, and the sewage guiding pipe 71 is arranged vertically.

[0037] As Figures 1 to 6 shown, the floor sweeping robot of this embodiment includes a housing 1, a separation structure 2, a sewage pipe 3, a movable pipe and an elastic member. Among them, the interior of the housing 1 has a storage chamber 10, the storage chamber 10 has an air inlet 101 and an air outlet 102. Specifically, the air outlet 102 is located on the top wall plate of the storage chamber 10. A fixed pipe 11 that is arranged vertically and communicates with the storage chamber 10 is provided in the aforementioned storage chamber 10, and there is a gap between the bottom edge of the fixed pipe 11 and the bottom wall of the storage chamber 10. The bottom of the fixed pipe 11 has an opening 111.

[0038] As Figures 3 to 6 shown, the separation structure 2 is arranged in the storage chamber 10 and is at least used to separate dust and liquid. The above-mentioned fixed pipe 11 is located on the periphery of the separation structure 2. The aforementioned separation structure 2 includes an inner ring wall 21 and an outer ring wall 22 that are both in the shape of a vertical ring wall and a connecting plate 23 that connects the top edge of the inner ring wall 21 and the top edge of the outer ring wall 22. Among them, the inner ring wall 21 surrounds the periphery of the air outlet 102 and forms an air passage 210 that communicates with the air outlet 102. The first filter holes 211 are distributed on the inner ring wall 21, and the second filter holes 221 are distributed on the outer ring wall 22. In addition, a transverse fixed plate 12 is provided in the storage chamber 10, the fixed plate 12 is located in the air passage 210, and the outer peripheral edge of the fixed plate 12 is in contact with the inner peripheral wall of the inner ring wall 21.

[0039] As Figures 3 to 6As shown, the sewage discharge pipe 3 is located within the fixed pipe 11. A baffle plate 4 is provided at the bottom of the sewage discharge pipe 3 and is positioned below the fixed pipe 11. Moreover, a sewage discharge port 30 is formed on the peripheral wall of the sewage discharge pipe 3 and is above the baffle plate 4. Specifically, the sewage discharge pipe 3 includes a vertically arranged vertical pipe body 31 and an extension wall 32 provided on the bottom wall of the vertical pipe body 31 and extending downward. There are two extension walls 32 and they are arranged at intervals. In this embodiment, the two extension walls 32 are arranged opposite to each other. The bottom edges of the two extension walls 32 are connected by a flexible connection wall 33. The connection wall 33, the bottom wall of the vertical pipe body 31, and the two extension walls 32 enclose the above-mentioned sewage discharge port 30. The connection wall 33 includes two inclined walls 331 and a transverse wall 332 located between the two inclined walls 331 and connected to both of them. The transverse wall 332 extends along the sequential arrangement direction of the two extension walls 32. The two inclined walls 331 are inclined upward and gradually away from each other. The upper end of each inclined wall 331 is connected to the lower end of the corresponding extension wall 32. The above-mentioned flexible connection wall 33 can be compressed. Since there is a relatively large water passing area before compression, when the sewage discharge pipe is continuously pressed down until it reaches the bottom wall of the storage chamber, the water passing area will be reduced a lot. The transverse wall moves upward. When the purified water enters the storage chamber through the sewage discharge pipe, under the combined action of the water pressure and the downward pressure of the vertical pipe body (similar to pressing the water pipe opening by hand for spraying), the water sprays towards the side wall of the storage chamber, and at the same time, it can clean the separation structure, achieving a good self-cleaning effect of flushing the side wall of the storage chamber and the separation structure.

[0040] The baffle plate 4 is installed on the transverse wall 332 of the connection wall 33. In this embodiment, a convex portion 41 extending upward is provided at a position near the center of the upper wall surface of the baffle plate 4. A jack 330 is formed at a position near the center of the connection wall 33 for the convex portion 41 to be inserted upward therein. In order to detect the liquid level height in the storage chamber, a detection member for sensing the liquid level height in the storage chamber 10 is provided on the bottom wall of the vertical pipe body 31 in the area other than the extension wall 32. The detection member is an electrode contact 312, and there are two of them and they are arranged opposite to each other at intervals. The extension wall 32 is located between the two detection members. In this way, according to the contact between the electrode contact 312 and the liquid surface in the storage chamber, the remaining situation of the internal liquid in the storage chamber is judged. If it has been in the triggered state all the time, then continue to control the sewage guiding pipe to press down the sewage discharge pipe until the contact is not triggered, which indicates that the recovery in the storage chamber has been completed.

[0041] The above-mentioned sewage discharge pipe 3 is fixedly connected to the separation structure 2 relatively. In this embodiment, the baffle plate 4 is connected to the separation structure 2 through a connecting rod 5. Specifically, the connecting rod 5 is connected to the bottom edge of the outer ring wall 22. The above-mentioned sewage discharge pipe 3 is arranged to be able to move up and down relative to the fixed pipe 11, so the sewage discharge pipe 3 and the separation structure 2 move up and down together. The above-mentioned sewage discharge pipe 3 has the following two states during the up and down movement: such as Figure 3 and Figure 4As shown, in the first state, the baffle plate 4 of the sewage discharge pipe 3 blocks the opening 111 of the fixed pipe 11, and the sewage discharge port 30 is located in the space enclosed by the baffle plate 4 and the fixed pipe 11. As Figure 5 and Figure 6 shown, in the second state, the sewage discharge pipe 3 moves downward until its baffle plate 4 opens the opening 111 of the fixed pipe 11, and the sewage discharge port 30 is communicated with the storage chamber 10.

[0042] In this embodiment, the above-mentioned sewage discharge pipe 3 can move downward under the push of the movable pipe. The aforementioned movable pipe is the sewage guiding pipe 71. When the cleaning machine is in the accommodating chamber 70, the sewage guiding pipe 71 is located above the sewage discharge pipe 3, is arranged corresponding to the sewage discharge pipe 3, and can be communicated with the sewage discharge pipe 3. When docking and recycling are required, the sewage guiding pipe 71 descends, pressing down the sewage discharge pipe 3 until the sewage discharge port 30 on it is in an open state. At this time, the sewage and garbage in the storage chamber 10 are introduced into the sewage collection tank of the base or the sewer through the sewage discharge port, the sewage discharge pipe, and the sewage guiding pipe 71. The structure for realizing the up and down movement of the sewage guiding pipe 71 adopts the structure in the prior art and will not be described in detail in this embodiment.

[0043] The elastic member acts on the sewage discharge pipe 3 and makes the sewage discharge pipe 3 always have a tendency to move upward. Under the action of the aforementioned elastic member, the sewage discharge pipe moves upward, and the baffle plate 4 on the sewage discharge pipe 3 blocks the opening 111 of the fixed pipe 11. The aforementioned elastic member is a spring 9 located in the fixed pipe 11 and sleeved outside the sewage discharge pipe 3. The top circumference of the sewage discharge pipe 3 has a flange 311 extending outward. The opening 111 is opened on the bottom wall plate of the fixed pipe 11. The spring 9 is located between the flange 311 and the bottom wall plate of the fixed pipe 11. In this embodiment, the flange 311 gradually slopes upward from the inside to the outside. When the movable pipe is in a state of pushing the sewage discharge pipe 3 to move downward, the bottom edge of the movable pipe abuts against the flange 311.

[0044] After a round of cleaning, some fluff will accumulate on the separation structure 2. Under the downward pressure of the sewage guiding pipe on the sewage discharge pipe 3, the sewage discharge pipe 3 drives the separation structure to descend together. After descending to a certain height, water is added to the storage chamber (the clean water can be input into the storage chamber through the clean water tank of the base through the sewage guiding pipe and the sewage discharge pipe). After adding to a certain capacity, the fan drives the clear water in the storage chamber to wash the fluff accumulated on the separation structure, and then negative pressure recovery is carried out through the sewage discharge pipe. After the entire process is completed, the sewage discharge pipe rises to the first state.
