Intelligent cleaning system, autonomous robot and base station

Technical Field

The utility model relates to a burnisher field specifically relates to an intelligence cleaning system, autonomous robot and basic station with rubbish is retrieved function.

Background

Existing sweeping robots are equipped with a dust box that stores trash. After the dust box is filled with the garbage, the user needs to manually take out the dust box, clean the garbage therein, and then load the dust box into the sweeping robot. If the dust box is filled with garbage and is not cleaned in time, the cleaning effect of the sweeping robot can be influenced. The sweeping robot is small in size, accordingly, the dust box is small in volume, and the capacity of accommodated garbage is limited and the garbage can be filled easily. Therefore, the user is required to frequently and manually clean the dust box filled with the garbage in the daily use process, and the use experience of the user is seriously influenced. For example, when cleaning a large area of space, the cleaning may not be completed and the dust box may be filled. At this point, if there is no user intervention (cleaning the dust box), the sweeping robot either does not continue to sweep or continues to sweep but the sweeping effect is degraded.

Therefore, it is desirable to provide an intelligent cleaning system with garbage collection function, an autonomous robot and a base station to at least partially solve the above problems.

Detailed Description

In the following discussion, details are given to provide a more thorough understanding of the present invention. One skilled in the relevant art will recognize, however, that the invention may be practiced without one or more of the specific details. In certain instances, some features that are known in the art have not been described in detail in order to avoid obscuring the present invention.

Fig. 1 shows an intelligent cleaning system 1 according to the invention comprising an autonomous robot 10 and a base station 20. The autonomous robot 10 is designed to be autonomously movable on the ground to perform a cleaning function. The autonomous robot 10 is also designed to be able to autonomously move to the position of the base station 20 to dock with the base station 20 (the state shown in fig. 1) to evacuate the targets it collects during the performance of the cleaning function. The target may be waste such as paper dust, dirt, hair, or the like.

It is understood that the sweeping function of the autonomous robot 10 may include at least one of sweeping and mopping the floor. In the present embodiment, the autonomous robot 10 is a cleaning robot integrating sweeping and mopping. The autonomous robot 10 mainly includes a cleaning unit, a sensing unit, a control unit, a driving unit, an energy unit, a human-computer interaction unit, and the like. The units cooperate with each other to enable the autonomous robot 10 to move autonomously to perform a cleaning function.

Fig. 2 and 3 exemplarily show a perspective view of an autonomous robot 10 according to the present invention. The autonomous robot 10 has an approximately circular shape (circular front and rear) viewed from the outside, and includes an upper cover 11, a chassis 12, and a center frame 13 provided between the upper cover 11 and the chassis 12. The middle frame 13 serves as a base frame for arranging various functional elements. The upper cover 11 and the chassis 12 cover upper and lower surfaces of the middle frame 13, respectively, to protect internal components and improve the aesthetic property of the autonomous robot 10. Of course, in other embodiments, the device body may have other shapes as well, including but not limited to an approximate D-shape of a front-rear circle, and the like.

The driving unit is used to provide driving force for autonomous movement of the autonomous robot 10 and cleaning unit implementation of the sweeping function. The sensing unit is used for the autonomous robot 10 to sense an external environment such as a terrain, and provides various position information and motion state information of the machine to the control unit. The control unit comprehensively determines which working state the autonomous robot 10 is currently in (e.g., crossing a threshold, putting a carpet on, being located at, above or below a cliff, being stuck, being full of dust boxes, being picked up, etc.) according to the information, and gives specific next action strategies according to different situations. Further, the control unit can plan the most efficient and reasonable cleaning path and cleaning mode based on the instant map information, and the working efficiency of the autonomous robot 10 is greatly improved. The man-machine interaction unit is used for the user to select functions and/or showing the current state or function selection items of the machine to the user. The energy source unit is used for supplying electric energy for the operation of the functional elements of each unit.

The cleaning unit is the most important core unit of the autonomous robot 10, and is used to implement a sweeping function, and includes a dry cleaning part and a wet cleaning part. Among them, the dry type cleaning part is mainly used for sweeping and collecting an object such as solid particle contaminants on a surface to be cleaned, and the wet type cleaning part is mainly used for wiping the surface to be cleaned (such as a floor).

Specifically, the dry cleaning portion mainly includes a cleaning brush for picking up an object from a surface to be cleaned, and a first containing portion for collecting and containing the object and a suction device. As shown in fig. 3, the sweeper brush includes a main brush 14 and an edge brush 15. Wherein the main brush 14 has an axis of rotation substantially parallel to the plane of the chassis 12 and projects outwardly from the chassis 12. Thus, the bristles or blades of the main brush 14 create some interference with the surface being cleaned beneath the chassis 12. The side brushes 15 are arranged at a bottom edge position with their rotation axes at an angle relative to the ground for moving an object into the sweeping area of the main brush 14.

The first accommodation portion and the suction device are provided inside the autonomous robot 10. Fig. 4 schematically shows the structure of the first container 16 and the suction device 17. The suction device 17 can communicate with the first container 16 through the first air duct 18, and is configured to generate an air flow having a suction effect through the first container 16. The first receiving portion 16 has an inlet (not shown). When the main brush 14 rotates, the object of the surface to be cleaned is taken up by the main brush 14 to a position close to the inlet of the first containing portion 16, and then collected and contained in the first containing portion 16 by the air flow generated by the suction device 17. Among them, the first accommodating part 16 may be configured as a dust box detachably or fixedly provided inside the autonomous robot 10, and the suction device 17 may be configured as a fan. Further, the first housing portion 16 may also be configured as a housing chamber or the like provided inside the autonomous robot 10, and the suction device 17 may also be configured as a fan or the like with a drive motor.

Preferably, a first filter device 161 may be disposed in the first air duct 18, so that when the autonomous robot 10 performs a sweeping function, the target objects entering the first receiving portion 16 along with the air flow remain in the first receiving portion 16, and only clean air is allowed to flow along the first air duct 18 to the suction device 17, so as to prevent the suction device 17 from being damaged by particles and the like. The first Filter device 161 may be configured as a High efficiency particulate air Filter (HEPA) or the like. Further preferably, a vibration device (not shown) attached to the first filter device 161 may also be provided. When the autonomous robot 10 performs the cleaning function, the vibration device drives the first filter device 161 to vibrate continuously, so that dust and the like attached to the first filter device 161 are removed by the vibration, and the first filter device 161 maintains a small air resistance and increases the acting force of the suction device 17.

The wet cleaning part mainly comprises a liquid storage tank and cleaning cloth. The liquid storage tank is internally provided with cleaning liquid, and the cleaning cloth is detachably arranged on the liquid storage tank. After the dry cleaning part finishes cleaning, the liquid in the liquid storage tank of the wet cleaning cloth flows to the cleaning cloth, and the cleaning cloth wipes the surface to be cleaned after the cleaning device cleans the surface.

Generally, the autonomous robot 10 is small in volume, which results in a very limited volume of the first accommodation portion 16 inside thereof. The first container 16 is easily filled with the collected object during daily use. In this state, the autonomous robot 10 is often configured to stop the cleaning work. The autonomous robot 10 is forcibly instructed to continue to perform the cleaning work in time, and the cleaning effect is deteriorated because the target object such as the solid particle contaminant cannot be continuously collected.

Therefore, the autonomous robot 10 according to the present invention is also designed to be able to autonomously move to a position of the base station 20 to dock with the base station 20 (the state shown in fig. 1) to evacuate the target object it collects during the execution of the cleaning function, so as not to affect the cleaning function. For example, when the first container 16 is filled with the target object, the detection device for detecting the filling state of the first container 16 within the autonomous robot 10 may transmit a signal indicating that the first container 16 is filled to the control unit. After receiving the signals, the control unit searches for the base station 20 according to a navigation algorithm stored in the control unit, and controls the autonomous robot 10 to autonomously move to the base station 20 to be in butt joint with the base station 20 according to a map constructed by the autonomous robot, the position of the autonomous robot in the map, indication signals sent by sensing devices arranged on the autonomous robot 10 and the base station 20, and the like, so as to execute an emptying function.

Fig. 5 and 6 schematically show a preferred embodiment of a base station 20 according to the invention. The base station 20 is provided with a second housing portion 22 therein. The volume of the second receiving portion 22 may be designed to be much larger than the volume of the first receiving portion 16. Further, a second air duct 21 and a third air duct 23, which communicate with the second housing portion 22, respectively, are provided in the base station 20. As shown in fig. 5, the second air duct 21 forms an opening 211 of the second air duct 21 on the outer surface of the base station 20, and the third air duct 23 forms an opening 231 of the third air duct 23 on the outer surface of the base station 20.

Accordingly, as shown in fig. 4, the autonomous robot 10 is also provided with an evacuation port 162 and a return air port 172, which are not directly connected. The evacuation port 162 is communicated with the first accommodating portion 16, and the return air port 172 is communicated with the suction device 17. When the autonomous robot 10 is docked with the base station 20 in the manner shown in fig. 1, as shown in fig. 7, the evacuation port 162 of the autonomous robot 10 communicates with the opening 211 of the second air duct 21 of the base station 20, and the return air port 172 of the autonomous robot 10 communicates with the opening 231 of the third air duct 23 of the base station 20. At this time, the first air passage 18 may be cut off so that the suction device 17 can communicate with the first container 16 only through the third air passage 23, the second container 22, and the second air passage 21. In this state, the air flow having the suction function generated by the suction device 17 flows to the suction device 17 along the first accommodating portion 16, the evacuation port 162, the opening 211 of the second air duct 21, the second accommodating portion 22, the third air duct 23, the opening 231 of the third air duct 23, and the air return port 172 in sequence, so as to drive the target object accommodated in the first accommodating portion 16 to be transferred into the second accommodating portion 22.

Although not shown in the drawings, a sealing member such as a sealing ring may be provided between the evacuation port 162 and the opening 211 of the second air duct 21, and between the return air port 172 and the opening 231 of the second air duct 21, to enhance the sealing performance and prevent leakage.

It is understood that when the autonomous robot 10 performs the cleaning function, the evacuation port 162 needs to be kept closed to prevent the object in the first receiving portion 16 from leaking through the evacuation port 162 and causing recontamination of the surface to be cleaned. While the return air opening 172 needs to be kept closed, the first air duct 18 is kept open to ensure that the suction force generated by the suction device 17 is fully applied to the first accommodating portion 16.

Further, the flow path of the air flow generated by the suction device 17 when the autonomous robot 10 performs the cleaning function is smaller than the flow path of the air flow when the autonomous robot 10 performs the evacuation function. Therefore, to ensure sufficient suction force, the autonomous robot 10 is configured such that the operating power of the suction device 17 when performing the evacuation function is greater than that when performing the cleaning function.

As shown in fig. 6, a dust bag 27 may be provided in the base station 20. The dust bag 27 is detachably provided in the second receiving portion 22 to facilitate a user to clean and replace the full dust bag 27. The dust bag 27 communicates with the second air duct 21 to accommodate the object evacuated from the first accommodating portion 16. The dust bag 27 itself may have a filtering function to maintain the interior space of the dust bag 27 in fluid communication with the third air duct 23. In this manner, the air carrying the object flows through the dust bag 27, and the object remains in the dust bag 27. The clean air flows along the third air duct 23 to the suction device 17.

In other embodiments, the dust bag 27 may not be provided, and the second accommodating portion 22 may be provided as an accommodating chamber or a dust box. A second filter device 26 is provided at a position where the second receiving portion 22 communicates with the third air duct 23 to retain the object in the second receiving portion 22, allowing only clean air to pass therethrough. The second filter device 26 may have the same configuration as the first filter device 161.

Preferably, although not shown in the drawings, a check valve may be further provided in the second air duct 21 or between the second air duct 21 and the second receiving portion 22. The check valve is configured to be openable only toward the air flow direction in the second duct 21 shown in fig. 7 (i.e., toward the second receiving portion 22) and not to be openable reversely. The one-way valve has a substantially horizontally extending axis of rotation, which may be configured to open in response to the suction action of the suction device 17 and to close in response to the action of gravity after the suction device 17 has ceased to operate. As such, when the evacuation function is performed, the check valve opens to allow a mixed flow of the target and air to pass therethrough. In other states, the check valve is closed to prevent the target in the second container 22 from leaking through the second air duct 21.

After the first container 16 has been emptied, the detection device sends a signal to the control unit that the emptying is complete. If the control unit stores the command of the cleaning task which is not completed, the control unit controls the autonomous robot 10 to autonomously move to the position indicated by the cleaning task command to execute the corresponding cleaning function after receiving the emptying-completed signal. And if a command for a cleaning task that has not been completed is not stored in the control unit at this time, the control unit may control the autonomous robot 10 to stand by for receiving the command for the cleaning task, for example, may stand by on the spot, or may stand by autonomously moving to a specified location. Or may control the autonomous robot 10 to directly shut down at a designated location in place or autonomously moved.

Of course, the autonomous robot 10 may also be configured to periodically perform the evacuation function at predetermined intervals, i.e., autonomously moving to interface with the base station 20 at the base station 20. In one embodiment, the base station 20 may be a charging pile for charging the autonomous robot 10. As such, the autonomous robot 10 may also be configured to perform an evacuation function once per charge.

From the foregoing, according to the utility model discloses a clean system of intelligence can be through switching over suction device 17 and first portion 16 of holding through the wind channel intercommunication of difference in order to carry out respectively and clean function and evacuation function. Thus, only one suction device 17 is required to be arranged on the autonomous robot 10, and an additional suction device is not required to be arranged on the base station 20, so that the cost is saved, the installation space of the base station 20 is saved, and the structure is compact.

The switching between the different air paths for communicating the suction device 17 with the first container 16 can be realized by electronic components such as solenoid valves controlled by the control unit according to a control program stored in the control unit, or by linkage between simple mechanical devices. In the present embodiment, the opening and closing of each air duct is realized by the opening and closing of a valve.

As shown in fig. 4, a substantially vertical wall 164 is provided between the suction device 17 and the first container 16, and a vent 165 is provided on the wall 164. The vent 165 is configured as part of the first air chute 18. The side of the wall 164 facing the suction device 17 is also provided with a first valve 171. The first valve 171 is rotatable about a first axis AX 1. Wherein the first axis AX1 is located above the vent opening 165 and extends in a generally horizontal direction. The arrangement is such that when the suction device 17 ceases to operate, the first valve 171 automatically abuts against the wall 164 to cover the vent 165 in response to the action of gravity, thereby shutting off the first air duct 18. When the air flow having a suction effect is generated by the suction device 17, the first valve 171 is pushed by the air flow to rotate upward around the first axis AX1 (the state shown in fig. 4), and the suction device 17 can communicate with the first container 16 through the ventilation opening 165, and the first air duct 18 can be regarded as being in an open state.

With continued reference to fig. 4, the autonomous robot 10 is provided with a second valve 163 at the evacuation port 162 to control the evacuation port 162 to open or close, and a third valve 173 at the return air port 172 to control the return air port 172 to open or close. Specifically, the second valve 163 is mounted inside the drain 162, and is rotatable about the second axis AX 2. The plane of the drain 162 is substantially horizontal, and therefore the second valve 163 covers the drain 162 to close the drain 162 when only gravity is applied. Also, it is necessary for the second valve 163 to overcome its weight to rotate about the second axis AX2 to open the drain 162. In performing the cleaning function, although the suction force generated by the suction device 17 in the first container 16 acts on the second valve 163, it is not sufficient to overcome the gravity thereof, and thus it is possible to ensure that the evacuation port 162 remains closed during the performance of the cleaning function by the autonomous robot 10 without being opened by the suction device 17.

It will be appreciated that the plane in which the evacuation port 162 is located may also be inclined to the horizontal within a predetermined range of angles, but the angle should not be so great as to reduce the effect of gravity and allow the second valve 163 to open in response to the action of the suction device 17. The return air opening 172 and the third valve 173 have the same configuration as the drain opening 162 and the second valve 163, and are not described in detail herein.

As shown in fig. 5, the base station 20 is provided with a platform part 25 for receiving the autonomous robot 10 to perform docking. The platform part 25 has an upper surface inclined downward in a direction away from the base station 20, which may facilitate guiding the autonomous robot 10 to smoothly move onto the platform part 25. The opening 211 of the second air duct 21 and the opening 231 of the third air duct 23 are both provided on the upper surface of the platform portion 25.

Preferably, the upper surface of the platform 25 is provided with protrusions 24 at positions close to the opening 211 of the second air duct 21 and the opening 231 of the third air duct 23, respectively. When the autonomous robot 10 moves to the upper surface of the platform portion 25 to complete the docking, the protrusion 24 can push the second valve 163 to rotate inward in response to a state in which the autonomous robot 10 is docked in place to open the evacuation port 162 and align with the opening 211 of the second air duct 21 (a state shown in fig. 7), enabling the first accommodation portion 16 to communicate with the second air duct 21. The third valve 173 is also opened in the same manner.

Of course, the second valve 163 and the third valve 173 may be configured to be opened and closed integrally by providing only the protrusion 24 corresponding to one of the second valve 163 and the third valve 173. For example, both are constructed as an integrally formed unitary structure, or both are separately formed and connected using an additional connecting member to achieve integral opening and closing. This can avoid providing excessive parts on the surface of the platform portion 25.

Preferably, as shown in fig. 7, an extension 174 extending downward is provided below the first valve 171. The positions of the first valve 171 and the third valve 173 are suitably designed such that when the third valve 173 is opened, it abuts against the extension 174, restraining the first valve 171 in the closed position, enabling linkage. Therefore, the limiting function of the third valve 173 on the first valve 171 ensures that the first air duct 18 is cut off when the air return opening 172 is opened, thereby ensuring that the emptying function is performed smoothly. It will be appreciated that during docking of the autonomous robot 10 with the base station 20, the suction device 17 is in a deactivated state, in which the first valve 171 is in a closed state in response to the action of gravity. Therefore, the third valve 173 can be smoothly opened and the first valve 171 can be stopped, and the situation that the third valve 173 cannot act on the extension portion 174 to stop the first valve 171 when the third valve 173 is opened and the first valve 171 is in an opened state is avoided.

In addition, in other embodiments, the first valve and the third valve may be configured to be opened and closed integrally, such that the third valve is necessarily closed when the first valve is in the open state, and the third valve is necessarily opened when the first valve is in the closed state.

As shown in fig. 8 to 10, the first valve 271 and the third valve 273 are constructed as an integrally molded unitary structure. In performing the purge function, as shown in fig. 9, the third valve 273 closes the air return opening 272, and the first valve 271 is far away from the air vent 265, so that the first air channel is kept open. While performing the evacuation function, as shown in fig. 10, the third valve 273 is rotated about the axis of rotation AX4 to an open position by action of a protrusion or other component such as those described above. At the same time, the first valve 271 rotates integrally with the third valve 273 from the open position to the closed position covering the vent 265. Therefore, the number of parts can be reduced, and the processing efficiency during equipment assembly is improved. However, it should be noted that in this embodiment, the first valve 271 cannot be opened or closed in response to the suction action of the suction device, and cannot be closed in response to the action of gravity, and can be opened or closed only integrally with the third valve 273. In other words, the third valve 273 remains normally closed while the first valve 271 remains normally open during functions other than performing an evacuation function.

In addition, combine the setting of the integrative switching of second valve and third valve above, not violating the utility model discloses a under the prerequisite of utility model thought, can also be with first valve, second valve and third valve overall structure as integrated into one piece's structure.
