Description

Technical Field

[0001] This invention belongs to the field of household washing and cleaning, and specifically relates to a cleaning machine and cleaning system. Background Technology

[0002] Currently, cleaning machines are floor scrubbers, vacuum cleaners, or sweepers. Vacuum cleaners or sweepers suck up a mixture of dust and moisture from the ground into their storage chamber. In order to separate the mixture of dust particles and moisture, cleaning machines usually use a separation device, which typically contains a separation component. The separated airflow is then discharged through the air outlet of the storage chamber.

[0003] Existing separation devices, such as the applicant's earlier Chinese utility model patent application "A Separation Module and Cleaning Machine for a Cleaning Machine," patent number ZL202120901488.0 (authorization announcement number CN216293938U), disclose a cleaning machine including a housing with a storage cavity for holding waste inside. The housing has a drain outlet communicating with the storage cavity. A drain pipe is disposed on the housing and is vertically arranged. The lower end of the drain pipe has an opening communicating with the storage cavity, and the top opening of the drain pipe is the drain outlet. At least a portion of the bottom surface of the storage cavity is an inclined surface that gradually slopes downwards towards the opening of the drain pipe. Another example is patent number ZL202120889349.0 (authorization announcement number CN215534086U), which also discloses a partially inclined bottom surface of the storage cavity, with a filter and a fan installed downstream of the air outlet.

[0004] In the aforementioned patent, the bottom surface of the storage chamber is inclined, allowing the waste inside to move towards the opening under its own gravity. A drain pipe connects to the storage chamber, allowing waste located at the opening to be discharged along the drain pipe. However, the bottom space of the storage chamber is uneven, with one side larger than the other. This uneven bottom space can easily lead to uneven airflow, resulting in uneven wind speeds entering the outlet through the inner flow channels of the annular wall. If there is wastewater in the storage chamber, a higher maximum wind speed makes it easier for wastewater to be carried into the inner flow channels of the annular wall and into the inlet of the outlet channel, thus affecting the service life of subsequent filters and the fan.

[0005] Therefore, further improvements are needed to the existing cleaning machines. Summary of the Invention

[0006] The first technical problem to be solved by the present invention is to provide a cleaning machine that reduces the probability of sewage flowing upward while ensuring uniform airflow at the bottom of the storage chamber, in light of the current state of the prior art.

[0007] The second technical problem to be solved by the present invention is to provide a cleaning system that can more thoroughly clean up the waste in the storage chamber.

[0008] The third technical problem to be solved by the present invention is to provide a cleaning system that automatically opens the drain outlet and automatically discharges sewage.

[0009] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a cleaning machine, comprising:

[0010] A housing having an internal storage chamber for containing waste, the housing having a drain outlet communicating with the storage chamber;

[0011] A drain pipe is installed on the housing and arranged vertically. The lower end of the drain pipe has an opening that communicates with the storage chamber, and the top opening of the drain pipe is the drain outlet.

[0012] The feature is that the bottom surface of the storage chamber has a downwardly recessed groove near the opening, and the area of ​​the bottom surface of the storage chamber other than the groove is horizontally arranged.

[0013] To facilitate the entry of wastewater from the bottom of the storage chamber into the recess, at least a portion of the inner sidewall of the recess is an inclined surface that gradually slopes downwards towards the area away from the storage chamber. The presence of the inclined surface improves the drainage of wastewater.

[0014] In order to allow the sewage in the groove to flow out through the opening in a timely manner, the opening is at least partially located above the groove, and the orthographic projection of the opening along the vertical direction is located inside the groove.

[0015] To guide airflow, the top of the storage chamber has an air outlet, and the storage chamber has an annular component whose annular wall surrounds the air outlet and forms a flow channel communicating with the air outlet.

[0016] To improve separation capability, the flow channel has a separator for separating at least dust and liquid, and a gap is left between the separator and the annular wall of the annular member to allow airflow.

[0017] To allow the drain outlet to be opened or closed as needed, a cover plate is included, which is arranged to move relative to the drain outlet to open or close it. Thus, when the cover plate closes the drain outlet, it prevents odors from flowing out and also prevents wastewater from flowing out after the cleaning machine is tilted; when drainage is required, the drain outlet can be opened via the cover plate.

[0018] The cover plate can be opened by moving up and down or by rotating, and the cover plate is rotatably installed at the drain outlet of the drain pipe.

[0019] The groove and the opening can be staggered. By setting a guide strip, the sewage in the groove is guided to the opening. Alternatively, the groove can be arranged to correspond with the opening, so that the sewage in the groove can be directly sucked into the opening. The groove is arranged to correspond with the opening.

[0020] The opening can be located on the bottom wall or the side wall of the sewage pipe, but preferably, the opening is located on the side wall of the sewage pipe, and the lower part of the sewage pipe has an inclined section that gradually slopes upwards away from the opening at a position opposite to the opening. Furthermore, the presence of the inclined section helps to guide the sewage entering the sewage pipe.

[0021] The drain pipe may be located inside or outside the storage chamber, but preferably, at least from the perspective of reducing the space occupied inside the storage chamber, the drain pipe is located outside the storage chamber and is formed on the side wall of the storage chamber, and a portion of the side wall of the drain pipe is part of the side wall of the storage chamber and has the opening described above.

[0022] To facilitate the flow of wastewater from the groove into the drain pipe, the bottom edge of the opening, the inner bottom surface of the drain pipe, and the bottom surface of the groove are flush.

[0023] More preferably, the lower part of the sewage pipe has an inclined section that gradually slopes upwards away from the opening at a position opposite to the opening, and the bottom edge of the inclined section is flush with the bottom surface of the groove. In this case, the sewage entering the sewage pipe flows out through the sewage outlet more effectively under the guidance of the inclined section.

[0024] Preferably, the lower part of the drain pipe has an inclined section that gradually slopes upwards away from the opening at a position opposite to the opening, and the top edge of the inclined section is located above the top edge of the opening. The top edge of the inclined section being located above the top edge of the opening prevents sewage guided by the inclined section from flowing into the storage chamber through the opening.

[0025] The cleaning machine can be a floor scrubber or a sweeper, but preferably, the cleaning machine is a sweeper.

[0026] There are several ways to achieve the rotation of the cover plate. It can be driven by a transmission mechanism or manually. However, from the perspective of operational reliability, it is preferable to also include a transmission mechanism to achieve the rotation of the cover plate, and the power output end of the transmission mechanism is connected to the cover plate drive.

[0027] There are various structural forms of transmission mechanisms, but preferably, the transmission mechanism includes:

[0028] The guide is arranged vertically on the periphery of the sewage pipe and has a guide channel extending in the vertical direction inside.

[0029] A connecting pipe, arranged vertically and connected to the cover plate, is inserted into the guide channel. Its sidewall has a guide groove that gradually extends downwards along the circumference of the connecting pipe.

[0030] The movable rod is inserted into the inner cavity of the connecting pipe. Its sidewall extends laterally to form a sliding part that slides with the guide groove. It is arranged to move in the up and down direction to drive the cover plate to rotate along the surface where the drain outlet is located, thereby opening or closing the drain outlet.

[0031] The movable lever can open the drain outlet when it is in a downward movement state or when it is in an upward movement state. However, preferably, when the movable lever is in a downward movement state, the cover plate rotates to the side of the drain outlet to open the drain outlet.

[0032] To increase the reliability of the drain opening, a connecting groove is provided below the guide groove and extends in the vertical direction. When the drain is open, the sliding part is located in the connecting groove. When the drain is closed, the sliding part is located near the top of the guide groove.

[0033] In order for the movable rod to automatically return to its original position, the transmission mechanism also includes an elastic element that acts on the movable rod and causes the movable rod to always have an upward tendency.

[0034] The movable rod can be manually driven downwards, or it can be automatically driven downwards by a drive mechanism. However, from the perspective of operational reliability and ease of use, it is preferable to include a drive mechanism for driving the movable rod downwards, and the power output end of the drive mechanism can be in contact with or connected to the movable rod.

[0035] The technical solution adopted by the present invention to solve the second technical problem mentioned above is: a cleaning system having the cleaning machine, characterized in that it includes a base, the base having a rear opening for the cleaning machine to enter forward into a receiving chamber, wherein the cleaning machine is located in the receiving chamber, the groove is located on the front side of the housing, and the area of ​​the bottom surface of the storage chamber gradually slopes from top to bottom toward the groove.

[0036] The storage chamber is tilted, which causes the waste inside to converge into the groove on the front side. During sewage discharge, the waste is more easily discharged through the opening, preventing waste from remaining at the bottom of the storage chamber and reducing the generation of moldy odors.

[0037] To discharge waste from the storage chamber, the base is equipped with a guide pipe that can move vertically. When the cleaning machine is located within the accommodating chamber, the guide pipe is positioned corresponding to the drain outlet, and the guide pipe can move downwards to communicate with the drain outlet. Thus, the waste in the storage chamber is discharged through the drain pipe and the guide pipe.

[0038] The technical solution adopted by the present invention to solve the third technical problem mentioned above is: a cleaning system having the cleaning machine described above, characterized in that: it includes a base, the base having a accommodating chamber with a rear opening for the cleaning machine to enter, the base being provided with a drive mechanism for driving the movable rod to move downward, the drive mechanism being at least partially located above the accommodating chamber, and the power output end of the drive mechanism being able to contact or connect with the movable rod.

[0039] In order to automatically achieve the purpose of sewage discharge while opening the cover, the base is provided with a sewage guide pipe that moves in the vertical direction under the drive of the drive mechanism. When the cleaning machine is located in the accommodating cavity, the sewage guide pipe is arranged corresponding to the sewage outlet, and the sewage guide pipe can move downward to be in a state of communication with the sewage outlet.

[0040] With the cleaning machine located in the accommodating chamber, the groove is located on the front side of the housing, and the area of ​​the bottom surface of the storage chamber gradually slopes downwards towards the groove.

[0041] Thus, after the cleaning machine enters the accommodating chamber of the base, the drive mechanism simultaneously moves the guide pipe and the movable rod downwards. During this process, the cover rotates, opening the drain outlet of the drain pipe. The guide pipe then aligns with the drain outlet of the drain pipe, allowing sewage and waste in the storage chamber to flow into and accumulate in the groove. The sewage and waste in the groove are then discharged through the drain pipe and guide pipe. After the discharge is complete, the drive mechanism moves the guide pipe and the movable rod upwards. During this process, the guide pipe disengages from the drain outlet, and the drive mechanism drives the cover to rotate and close the drain outlet. Throughout the entire process, the same drive mechanism is used to achieve the vertical movement of the guide pipe and the rotation of the cover, eliminating the need for a separate drive mechanism to rotate the cover, reducing the number of components and lowering costs.

[0042] Compared with the prior art, the advantages of the present invention are as follows: the bottom surface of the storage chamber has a downwardly recessed groove at the position corresponding to the opening, and the area of ​​the bottom surface of the storage chamber other than the groove is horizontally arranged. In this way, on the one hand, the fluid entering the storage chamber is evenly distributed at the bottom of the storage chamber, avoiding the problem of uneven airflow distribution caused by the existence of the slope at the bottom of the storage chamber, thereby making the subsequent air velocity uniform and making it less likely for sewage and other substances in the storage chamber to move upward, thereby improving the service life of the subsequent filter and fan; on the other hand, sewage and garbage in the storage chamber can easily enter the groove, and the groove is arranged near the opening, making it easier to discharge garbage along the drain pipe after passing through the opening.

[0052] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0053] like Figure 1 As shown, the cleaning system of this embodiment includes a cleaning machine and a base station. The aforementioned cleaning machine is a sweeper 01. The base station of this embodiment includes a base 7, a drive mechanism 6, and a dirt guide pipe 8. The base 7 has a accommodating chamber 70 with a rear opening for the sweeper 01 to enter forward. The drive mechanism 6 is disposed on the base 7 and is at least partially located above the accommodating chamber 70.

[0054] like Figures 2 to 6 As shown, the sweeper 01 includes a housing 1, a drain pipe 11, a transmission mechanism, and a cover plate 2. The housing 1 has a storage chamber 10 for holding wastewater and / or garbage. The drain pipe 11 is vertically mounted on the housing 1, located outside the storage chamber 10, and formed on the side wall of the storage chamber 10. A portion of the side wall of the drain pipe 11 is part of the side wall of the storage chamber 10, and an opening 110 communicating with the storage chamber 10 is provided on the side wall shared by the drain pipe 11 and the storage chamber. The opening 110 is located at the lower end of the drain pipe 11.

[0055] like Figure 2 and Figure 6 As shown, the top opening of the aforementioned sewage pipe 11 is the sewage outlet 111. The cover plate 2 is arranged to move relative to the sewage outlet 111 to open or close the sewage outlet 111. The cover plate can be rotated or moved up and down, but in this embodiment, the cover plate 2 is rotatably disposed at the sewage outlet 111 of the sewage pipe 11 under the transmission drive of the transmission mechanism. Figures 3 to 7 As shown, the transmission mechanism includes a guide member 3, a connecting pipe 4, a movable rod 5, and an elastic element. The guide member 3 is vertically arranged around the drain pipe 11 and is fixedly connected to the drain pipe 11. The guide member 3 has a guide channel 31 extending in the vertical direction inside. The cover plate 2 can rotate along the surface where the drain outlet 111 is located, thereby opening or closing the drain outlet 111. Specifically, the cover plate 2 is provided with a vertically arranged connecting pipe 4, which is inserted into the guide channel 31. The side wall of the guide pipe 4 has a guide groove 41 that gradually extends from top to bottom along the circumference of the connecting pipe 4. Below the guide groove 41, there is a connecting groove 42 that communicates with the guide groove 41 and extends in the vertical direction. See details below. Figure 9 As shown. In this embodiment, there are two sets of guide grooves 41 and connecting seats 42, which are arranged at intervals along the circumference of the connecting pipe 4. The movable rod 5 is inserted into the inner cavity of the connecting pipe 4. The outer peripheral wall of the movable rod 5 has a laterally extending step 52 near the top. In this embodiment, the step 52 is annular and extends circumferentially along the movable rod 5. The guide channel 31 has a limiting part 311 near the bottom, which is located above the step 52 and restricts the downward movement of the step 52. The outer peripheral wall of the aforementioned step 52 extends laterally to form a sliding part 51, which slides in cooperation with each set of guide grooves 41 and connecting grooves 42. There are two sliding parts 51, which are arranged at intervals along the circumference of the movable rod 5. Each sliding part 51 corresponds to a set of guide grooves 41 and connecting grooves 42. Figure 3 , Figure 4 and Figure 6 and Figure 7As shown, the elastic element acts on the movable rod 5, causing the movable rod 5 to always have an upward tendency. Specifically, the elastic element is a spring 9 sleeved on the movable rod 5 and located between the step 52 and the limiting part 311.

[0056] like Figures 5 to 7 As shown, the aforementioned movable rod 5 can move vertically under the drive of the drive mechanism 6, so that the guide groove 41 and the connecting groove 42 slide in cooperation with the sliding part 51, thereby causing the connecting pipe 4 to rotate around its own axis and then causing the cover plate 2 to rotate along the surface where the drain outlet is located to open or close the drain outlet 111. Specifically, the power output end of the drive mechanism 6 can contact the movable rod 5, and can also be connected to the movable rod 5. When the movable rod 5 is in the downward movement state, the sliding part 51 is located in the connecting groove 42, and the cover plate 2 rotates to the side of the drain outlet 111 to open the drain outlet 111; when the drain outlet 111 is in the closed state, the sliding part 51 is located near the top of the guide groove 41.

[0057] like Figure 4 and Figure 6 As shown, the bottom wall of the storage chamber 10 has a downwardly recessed groove 101 near the opening 110. The groove 101 is arranged correspondingly to the opening 110. Specifically, the opening 110 is at least partially located above the groove 101, and the orthographic projection of the opening 110 along the vertical direction lies within the groove 101. The bottom surface of the storage chamber 10, excluding the groove 101, is horizontally arranged in the region 102. The inner sidewall of the groove 101 is an inclined surface 1011 that gradually slopes downwards away from the region 102. In addition, the lower part of the above-mentioned sewage pipe 11 has an inclined section 112 that gradually slopes away from the opening 110 from bottom to top at a position opposite to the opening 110. The inner bottom surface of the sewage pipe 11 is flush with the bottom edge of the inclined section 112, and the bottom edge of the inclined section 112, the bottom edge of the opening 110, and the bottom surface of the groove 101 are flush. The top edge of the inclined section 112 is located above the top edge of the opening 110. In this embodiment, the bottom surface of the groove 101 is arranged horizontally.

[0058] like Figure 4As shown, the aforementioned drain pipe 8 moves up and down under the drive of the aforementioned drive mechanism 6. Therefore, both the drain pipe 8 and the movable rod 5 are driven and connected to the power output end of the drive mechanism 6. The aforementioned drive mechanism 6 includes a motor 61, a screw 62, a nut 63, and a push rod 64. The screw 62 is arranged vertically and is driven and connected to the output shaft of the motor 61. The nut 63 is threaded onto the screw 62, and the drain pipe 8 is connected to the nut 63. The push rod 64 is arranged vertically and is correspondingly arranged to the movable rod 5, and is connected to the drain pipe 8. In this way, the drain pipe 8 moves up and down, and the push rod 64 also moves up and down. In this embodiment, the push rod 64 is located above the movable rod 5 and is correspondingly arranged to the movable rod 5. Therefore, when the push rod moves downward, it will push the movable rod 5 downward. With the sweeper 01 positioned within the accommodating chamber 70, the groove 101 is located on the front side of the housing 1. The bottom area 102 of the storage chamber 10 gradually slopes downwards towards the groove 101. The guide pipe 8 is arranged correspondingly to the drain port 111, and the guide pipe 8 can move downwards to communicate with the drain port 111. Furthermore, in this embodiment, when the push rod 64 moves upwards, the movable rod 5 and the guide pipe 8 move upwards together under the action of the spring 9. Alternatively, when the motor reverses, the movable rod and the guide pipe can be actively driven upwards by the cooperation of the screw and nut.

[0059] After the sweeper enters the accommodating chamber 70 of the base 7, the drive mechanism 6 simultaneously drives the guide pipe 8 and the movable rod downwards. During this process, the cover plate 2 rotates, opening the drain port 111 of the drain pipe 11. The guide pipe 8 then connects with and is linked to the drain port 111 of the drain pipe 11. Sewage and garbage in the storage chamber 70 flow into the groove 101 and accumulate there. The sewage and garbage in the groove 101 are then discharged through the drain pipe 11 and the guide pipe 8. After the sewage discharge is completed, the drive mechanism 6 drives the guide pipe 8 upwards. At this time, the movable rod 5 also moves upwards under the action of the spring. During this process, the guide pipe 8 disengages from the drain port 111, and the cover plate 2 rotates to close the drain port 111. Throughout the entire process, the same drive mechanism is used to achieve the up-and-down movement of the guide pipe 8 and the rotation of the cover plate 2, eliminating the need for a separate drive mechanism to achieve the rotation of the cover plate 2, thus reducing the number of parts and lowering costs.

[0060] like Figure 4 and Figure 6As shown, the storage chamber 10 has an air outlet 103 at its top. A filter (not shown) and a fan 9 are mounted on the housing. The air outlet 103, the filter, and the fan 9 are arranged sequentially along the fluid flow path. The aforementioned storage chamber 10 has an annular member 104. The annular wall of the annular member 104 surrounds the air outlet 103 and forms a flow channel 30 communicating with the air outlet 103. The flow channel 30 has a separator for at least separating dust and liquid. A gap is left between the separator and the annular wall of the annular member 104 for airflow. In this embodiment, the separator is a horizontally arranged separator plate 4.

[0061] Taking the direction of travel of the sweeper as forward, the orientation reference in this embodiment is... Figure 1 The direction indicated by the middle arrow.

[0062] The specification and claims of this invention use terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," to describe various exemplary structural parts and elements of the invention. However, these terms are used herein merely for ease of explanation and are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this invention can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be considered as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.
