Technical Field

[0001] The present invention relates to the technical field of floor cleaning machines, particularly to a base station and a floor cleaning machine. Background Art

[0002] A floor cleaning machine includes a base station and a robot main body. The robot main body is used for cleaning the ground to be cleaned, and the base station is used for maintaining the robot main body. The specific maintenance items include but are not limited to cleaning the mopping member on the robot main body. The mopping member on the robot main body needs to be dried after cleaning to avoid bacteria breeding. Generally, the drying efficiency of the base station for the robot main body is relatively low. Summary of the Invention

[0003] Aiming at the problem of relatively low drying efficiency, the present invention provides a base station and a floor cleaning machine. By using a first air outlet and a second air outlet which are opposite and spaced apart to blow drying air, the air volume distribution in the drying groove is made more uniform, the mopping member is heated evenly, and thus the drying efficiency is improved.

[0004] A base station includes: a base station body. The base station body is provided with a receiving space for accommodating the robot main body. The bottom wall of the receiving space is provided with a drying groove. The opening of the drying groove faces the mopping member of the robot main body located in the receiving space. The groove wall of the drying groove is provided with a first air outlet and a second air outlet. Both the first air outlet and the second air outlet are used for blowing out drying air. The first air outlet and the second air outlet are opposite and spaced apart.

[0005] In one embodiment, the receiving space has an inlet and outlet for the robot main body to enter. The direction in which the robot main body enters the receiving space is the entering direction. The spacing direction of the first air outlet and the second air outlet is the first direction, and the first direction is perpendicular to the entering direction.

[0006] In one embodiment, a drying air duct is provided in the base station body. The drying air duct is communicated with both the first air outlet and the second air outlet. Among the multiple planes perpendicular to the first direction, the one equidistant from the first air outlet and the second air outlet is taken as a reference datum plane, and the drying air duct is a symmetric structure with the reference datum plane as the symmetry plane.

[0007] In one embodiment, a flow guide plate is provided at the first air outlet and / or the second air outlet.

[0008] In one embodiment, the included angle between the flow guiding direction of the flow guide plate and the entering direction is an acute angle, and the included angle between the flow guiding direction of the flow guide plate and the air outlet direction of the corresponding air outlet is an acute angle.

[0009] In one embodiment, a drying air duct is provided in the base station body. The drying air duct is communicated with both the first air outlet and the second air outlet. The portions of the drying air duct close to the first air outlet and the second air outlet are both end air duct segments. The end air duct segments are arranged in a direction parallel to the entering direction. The guide vane divides the corresponding air outlet into two sub-air outlets arranged in sequence along the entering direction, and the two sub-air outlets belonging to the same air outlet are both communicated with the corresponding end air duct segment.

[0010] In one embodiment, the flow direction of the air flow in the end air duct segment is opposite to the entering direction. Among the two sub-air outlets belonging to the same air outlet, the one located downstream along the air flow direction in the end air duct segment is the downstream sub-air outlet. The portion of the air duct wall of the end air duct segment facing the downstream sub-air outlet is the diversion wall. The diversion wall gradually inclines towards the downstream sub-air outlet in the air flow direction in the end air duct segment.

[0011] In one embodiment, the base station body includes a base assembly for carrying the robot main body. The base assembly includes a base body and a base cover plate. The base body is provided with a plurality of air guide partitions. Some of the air guide partitions are arranged along the layout path of the drying air duct, and some of the air guide partitions form the side walls of the drying groove.

[0012] The base cover plate covers each of the air guide partitions. The base cover plate, the base body, and some of the air guide partitions enclose the drying air duct. The base cover plate, the base body, and the remaining air guide partitions enclose the drying groove. The base cover plate is provided with an opening for forming the opening of the drying groove.

[0013] A floor sweeper includes a robot main body and the base station according to any one of the above. The robot main body can enter the accommodation space.

[0014] In one embodiment, the opening of the drying groove is a rectangular opening. The interval direction between the two short sides of the rectangular opening is the length direction of the rectangular opening, and the interval direction between the two long sides of the rectangular opening is the width direction of the rectangular opening. All the mopping parts of the robot main body form a mopping assembly.

[0015] The distance between the two farthest points on the mopping assembly in the length direction of the rectangular opening is the first distance, and the length of the rectangular opening is less than the first distance; and / or the distance between the two farthest points on the mopping assembly in the width direction of the rectangular opening is the second distance, and the width of the rectangular opening is less than the second distance.

[0016] In one embodiment, the lengths of the two ends of the wiping assembly protruding outside the rectangular opening are the same in the length direction of the rectangular opening;

[0017] In the length direction of the rectangular opening, the lengths of the two ends of the wiping assembly protruding outside the rectangular opening are both not greater than 20 mm.

[0018] In one embodiment, the lengths of the two ends of the wiping assembly protruding outside the rectangular opening are the same in the width direction of the rectangular opening;

[0019] In the width direction of the rectangular opening, the lengths of the two ends of the wiping assembly protruding outside the rectangular opening are both not greater than 20 mm.

[0020] The above solution provides a base station and a floor sweeper. By arranging the first air outlet and the second air outlet opposite to each other and at intervals, the air for drying can enter the drying groove from two opposite positions in a counter-flow manner, so that the drying air can be evenly distributed in the drying groove as much as possible. The air in the drying groove can then blow towards the wiping member, making the wiping member evenly heated and improving the drying efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0036] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0037] As Figure 1 and Figure 2 shown, the floor sweeper 10 includes a base station 20 and a robot host 11. After the robot host 11 finishes cleaning the ground, it can return to the base station 20 for cleaning. There will be water stains or other cleaning liquid residues on the mopping member 12 of the robot host 11 after being cleaned, and drying treatment is required.

[0038] To improve the drying efficiency, as Figure 3 and Figure 4As shown, in some embodiments, a base station 20 is provided, including a base station body 21, and an accommodation space for accommodating a robot host 11 is provided in the base station body 21.

[0039] Moreover, a drying groove 214 is provided on the bottom wall of the accommodation space, and the opening of the drying groove 214 faces the wiping member 12 of the robot host 11 located in the accommodation space. First air outlets 22 and second air outlets 23 are provided on the groove wall of the drying groove 214. Both the first air outlets 22 and the second air outlets 23 are used for blowing out drying air, and the first air outlets 22 and the second air outlets 23 are opposite and arranged at intervals.

[0040] As Figure 3 shown, the air blown out from the first air outlets 22 and the second air outlets 23 flows into the drying groove 214 in opposite directions, so that the drying air in the drying groove 214 is evenly distributed, and thus each part of the wiping member 12 is evenly heated, improving the drying efficiency.

[0041] In particular, as Figure 2 、 Figures 8 to 10 shown, in some embodiments, the wiping member 12 is a roller. The air outlet direction of the first air outlets 22 is along the axial direction of the roller, and the air outlet direction of the second air outlets 23 is also along the axial direction of the roller. The air blown out from the first air outlets 22 and the second air outlets 23 can both flow along the axial direction of the roller, quickly filling the entire drying groove 214, so that each part of the roller is evenly heated and the drying efficiency is relatively high.

[0042] The interval direction between the first air outlets 22 and the second air outlets 23 is parallel to the axial direction of the roller.

[0043] Furthermore, as Figures 1 to 4 shown, in some embodiments, the accommodation space has an inlet and outlet for the robot host 11 to enter, and the direction in which the robot host 11 enters the accommodation space is the entering direction. As Figure 3 shown by the arrow F1 in

[0044] is the entering direction. The interval direction between the first air outlets 22 and the second air outlets 23 is the first direction, and the first direction is perpendicular to the entering direction. Figure 2 、 Figures 8 to 10 shown, in some embodiments, the axial direction of the roller is parallel to the first direction. The robot host 11 includes two rollers, the axial directions of the two rollers are parallel, and the two rollers are arranged at intervals in the entering direction. During actual use, the roller that first enters the accommodation space along the entering direction is the front roller, and the other roller is the rear roller. After cleaning, the humidity of the front roller is greater than that of the rear roller. To make the front roller and the rear roller be dried as simultaneously as possible.

[0045] As Figure 6As shown, a flow guide plate 24 is further provided at the first air outlet 22 and / or the second air outlet 23. The function of the flow guide plate 24 is to guide the flow direction of the air, which can make the air field distribution in the drying groove 214 uniform or make the air volume in some areas of the drying groove 213 larger than that in other areas. For example, when the front drum is relatively wet and the rear drum is slightly dry, the air field distribution should focus on drying the front drum. The air volume in the area where the front drum is located can be increased through the flow guide ribs, and the air volume in the area where the rear drum is located is relatively small.

[0046] Further, the included angle between the flow guiding direction of the flow guide plate 24 and the entering direction is an acute angle, and the included angle between the flow guiding direction of the flow guide plate 24 and the air outlet direction of the corresponding air outlet is an acute angle.

[0047] As described above, generally, the humidity of the front drum in the accommodation space is relatively high when it first enters. Therefore, the flow guide plate 24 is arranged at the above-mentioned angle, so that the flow guide plate 24 guides the air flow to the side close to the front drum, and the air volume received by the front drum is larger, ensuring that the front drum and the rear drum can be dried as much as possible at the same time.

[0048] Specifically, in one embodiment, as Figure 6 and Figure 7 shown, the flow guide plate 24 divides the corresponding air outlet into two sub-air outlets 221 arranged in sequence along the entering direction.

[0049] In some embodiments, as Figures 5 to 9 shown, a drying air duct 215 is provided in the base station body 21, and the drying air duct 215 is communicated with both the first air outlet 22 and the second air outlet 23. The drying air duct 215 is used to guide the drying air sent by the air supply unit 25 to the first air outlet 22 and the second air outlet 23. In some embodiments, as Figure 11 shown, the air supply unit 25 includes a fan 251, a heating element 252, and an air supply pipe 253. The outlet of the air supply pipe 253 is communicated with the inlet of the drying air duct 215. The fan 251 is communicated with the air supply pipe 253 and is used to provide power for the air flow to form air that can be blown out from the two air outlets. The heating element 252 is arranged at the connection between the fan 251 and the air supply pipe 253 and is used to provide heat for the air flow.

[0050] The parts of the drying air duct 215 close to the first air outlet 22 and the second air outlet 23 are both end air duct sections, and the end air duct sections are arranged in a direction parallel to the entering direction. The two sub-air outlets 221 belonging to the same air outlet are both communicated with the corresponding end air duct section.

[0051] The flow guide plate 24 divides the air outlet into two sub-air outlets 221. The air blown out from one of the sub-air outlets 221 is significantly affected by the guiding action of the flow guide plate 24, and the guiding action on the air blown out from the other sub-air outlet 221 is relatively small.

[0052] In one embodiment, as Figures 5 to 7 shown, the flow direction of the air flow in the end air duct section is opposite to the entering direction. Two sub-air outlets 221 belonging to the same air outlet are arranged in sequence along the air flow direction in the end air duct section, and the one located more downstream is the downstream sub-air outlet 222.

[0053] The part of the air duct wall of the end air duct section facing the downstream sub-air outlet 222 is the diversion wall 2151. In the air flow direction of the end air duct section, the diversion wall 2151 gradually inclines towards the direction close to the downstream sub-air outlet 222. The diversion wall 2151 can guide the air flow that originally flows in the direction opposite to the entering direction in the end air duct section towards the downstream sub-air outlet 222, so that the air flow can flow out smoothly from the downstream sub-air outlet 222 and fill the drying groove 214.

[0054] More specifically, as Figures 5 to 7 shown, in one embodiment, the base station body 21 includes a base assembly for carrying the robot host 11. The base assembly includes a base body 211 and a base cover 213. The base body 211 is provided with a plurality of air guide partitions 212, and a part of the air guide partitions 212 are arranged along the layout path of the drying air duct 215, and another part of the air guide partitions 212 form the side walls of the drying groove 214;

[0055] The base cover 213 covers each of the air guide partitions 212. The base cover 213, the base body 211 and a part of the air guide partitions 212 enclose the drying air duct 215, and the base cover 213, the base body 211 and the remaining part of the air guide partitions 212 enclose the drying groove 214. The base cover 213 is provided with an opening for forming the opening of the drying groove 214.

[0056] The first air outlet 22 and the second air outlet 23 are formed on a part of the air guide partitions 212. The diversion wall 2151 belongs to a part of the air guide partitions 212 for enclosing the drying air duct 215.

[0057] Furthermore, in some embodiments, among the multiple planes perpendicular to the first direction, the one equidistant from the first air outlet 22 and the second air outlet 23 is used as a reference datum plane, and the drying air duct 215 is a symmetric structure with the reference datum plane as the symmetry plane. Thus, the air blown out from the first air outlet 22 and the second air outlet 23 is the same in both air volume and air speed, making the air flow distribution in the drying groove 214 more balanced.

[0058] In some other embodiments, a floor sweeper 10 is provided, which includes a robot main body 11 and the above-mentioned base station 20, and the robot main body 11 can enter the accommodation space. By arranging the first air outlet 22 and the second air outlet 23 opposite to each other and at intervals, the air for drying can enter the drying groove 214 from two opposite positions in a counter-flow manner, so that the drying air can be distributed as evenly as possible in the drying groove 214, and the air in the drying groove 214 can blow towards the mopping member 12, making the mopping member 12 evenly heated and improving the drying efficiency.

[0059] Specifically, as Figures 6 to 10 shown, in one embodiment, the opening of the drying groove 214 is a rectangular opening, the interval direction between the two short sides of the rectangular opening is the length direction of the rectangular opening, and the interval direction between the two long sides of the rectangular opening is the width direction of the rectangular opening.

[0060] All the mopping members 12 of the robot main body 11 form a mopping assembly. As Figure 9 shown, the distance between the two farthest points on the mopping assembly in the length direction of the rectangular opening is the first distance L1, and the distance between the two farthest points on the mopping assembly in the width direction of the rectangular opening is the second distance L2. In some embodiments, the mopping assembly includes two rollers, the axial directions of both rollers are parallel to the length direction of the rectangular opening, and the interval direction between the two rollers is parallel to the width direction of the rectangular opening. The axial length of the roller is the first distance, and the distance between the two farthest points on the two rollers in the interval direction is the second distance.

[0061] Considering the limited space in the base station 20, in some embodiments, the length of the rectangular opening is less than the first distance; and / or the width of the rectangular opening is less than the second distance. In other words, the edge area of the mopping assembly may not be directly opposite to the drying groove 214.

[0062] However, even if not all parts of the mopping assembly are directly opposite to the drying groove 214, in order to ensure the drying effect, the length of the edge of the mopping assembly exceeding the drying groove 214 should not be excessive.

[0063] Specifically, as Figures 8 to 10 shown, the length of the rectangular opening is less than the first distance, and the lengths of the two ends of the mopping assembly hanging outside the rectangular opening in the length direction of the rectangular opening are the same.

[0064] For example, in one embodiment, the lengths H1 of the two ends of the mopping assembly hanging outside the rectangular opening in the length direction of the rectangular opening are both not greater than 20 mm.

[0065] The width of the rectangular opening is less than the second spacing, and the lengths of both ends of the wiping assembly protruding outside the rectangular opening are the same in the width direction of the rectangular opening.

[0066] In one embodiment, the lengths of both ends of the wiping assembly protruding outside the rectangular opening are not greater than 20 mm in the width direction of the rectangular opening.

[0067] Of course, in other embodiments, the length of the rectangular opening may also be greater than or equal to the first spacing, and the width of the rectangular opening may also be greater than or equal to the second spacing.

[0068] Specifically, in one embodiment, the length of the rectangular opening is greater than the first spacing, and the two farthest points on the wiping assembly are both located between the two short sides of the rectangular opening in the length direction of the rectangular opening. The rectangular opening completely covers the wiping assembly in the length direction of the rectangular opening.

[0069] The width of the rectangular opening is greater than the second spacing, and the two farthest points on the wiping assembly are both located between the two long sides of the rectangular opening in the width direction of the rectangular opening. The rectangular opening completely covers the wiping assembly in the width direction of the rectangular opening.
