Description

Technical Field

[0001] The present invention relates to the field of household appliances, and particularly to a method for drying a cleaning part for a self - moving robot. On this basis, it also relates to a self - moving robot system for performing the method for drying a cleaning part for a self - moving robot. Background Art

[0002] With the popularization of smart home products, automated cleaning devices, especially floor - sweeping robots, have become part of modern family life. Floor - sweeping robots, with their autonomous navigation, cleaning path planning, and efficient cleaning functions, have greatly facilitated household cleaning work and reduced people's labor intensity.

[0003] However, despite the continuous improvement of the cleaning ability of floor - sweeping robots, the management of their cleaning parts remains an urgent problem to be solved. Especially for floor - sweeping robots integrated with a wet - mopping function, cleaning parts such as mops and rollers need to be cleaned and dried in a timely manner after use. Otherwise, bacteria will breed inside the cleaning parts themselves, which will greatly affect the cleaning effect of the floor - sweeping robot. At the same time, problems such as mildew of the cleaning parts will occur, resulting in frequent replacement of the cleaning parts. Most floor - sweeping robots do not have a drying function, and the cleaning and drying of cleaning parts usually require manual operation, which is time - consuming and laborious. Therefore, there is a need for a floor - sweeping robot that can automatically dry, so that the cleaning parts can be put into use again after being dried, without the need for manual disassembly, cleaning, and airing, thus saving manpower and improving the user experience.

[0004] To solve the inconvenience brought by manual cleaning of cleaning parts, the prior art uses an air duct structure capable of blowing out airflows to dry the cleaning parts. In the prior art, these air duct systems usually adopt a simple air outlet design, and the airflows directly blow from the air outlets towards the cleaning parts. Although this design can dry the cleaning parts to a certain extent, due to uneven air - flow distribution, the hot air cannot evenly cover the surface of the cleaning parts, resulting in poor drying effect. Therefore, in the prior art, the air duct is usually placed outside the air - supply device so that the air outlet of the external air duct can be directly aligned with the cleaning parts, and multiple air outlets are used to ensure that the hot air can directly and evenly blow on the cleaning parts. This makes it necessary to set the air duct outside in the prior art and then use an air - guiding part to guide the airflows to the cleaning parts.

[0005] The Chinese utility model patent CN221711816U discloses a cleaning base for accommodating a cleaning host. A cleaning groove corresponding to a cleaning part in the cleaning host is arranged on the upper surface of the cleaning base. A plurality of upward air outlets are arranged in the cleaning groove to blow air to the cleaning part when the cleaning part is located in the cleaning groove, so that the air flow can cover the cleaning part and dry the cleaning part evenly. The prior art ensures that all parts of the cleaning part can be blown by hot air by adding a plurality of air outlets for the straight surface cleaning part. However, the problem is that the external air duct arranged outside needs to occupy a certain space so that the air outlet can be as close to the cleaning part as possible, and the space occupied by the external air duct will make the air supply device with the external air duct take up too much floor space. For household appliances, the floor area occupied when they are placed largely determines their market competitiveness. Therefore, the problem that the base station takes up too much floor space due to the external air duct used for drying in the base station has become an urgent problem to be solved.

[0006] Therefore, a cleaning part drying method for a self - moving robot that can save external space is needed. Summary of the Invention

[0007] The object of the present invention is to solve the technical problem of how to provide a cleaning part drying method for a self - moving robot that can save external space.

[0008] To solve the above - mentioned technical problem, the first aspect of the present invention provides a cleaning part drying method for a self - moving robot, which includes the following steps: S1. The self - moving robot docks to the base station; S2. The base station generates a drying air flow, and makes the drying air flow be transported to the cleaning part of the self - moving robot through the air duct structure formed inside the self - moving robot to dry the cleaning part.

[0009] In some embodiments, the drying method provided by the present invention further includes: cleaning the cleaning part by using the base station after step S1 and before step S2.

[0010] In some embodiments, in step S2, the air duct structure divides the drying air flow generated by the base station into multiple strands distributed along the length direction of the cleaning part and guides the drying air flow to blow onto the surface of the cleaning part 1.

[0011] In some embodiments, a flow - guiding member is formed in the air duct structure to guide the drying air flow to blow onto the surface of the cleaning part in step S2.

[0012] In some embodiments, the flow - guiding member is arranged at the end of the air duct structure along the flow - through direction.

[0013] In some embodiments, the air duct structure is detachably connected with a flow - guiding member to guide the drying air flow to blow onto the surface of the cleaning part in step S2.

[0014] In some embodiments, the flow guide is arranged as a flow guide grille, and the grille vanes in the flow guide grille are arranged to extend along the flow-through direction, and an air flow channel allowing the drying air flow to pass through is formed between adjacent grille vanes.

[0015] In some embodiments, the drying air flow enters the flow guide through the air inlet cross-section of the flow guide, and along the direction of the air inlet cross-section, the interval between adjacent grille vanes gradually increases.

[0016] In some embodiments, along the flow-through direction, the grille vanes are radially distributed and extend towards the air outlet of the air duct structure.

[0017] In some embodiments, in the length direction of the air outlet, the grille vanes are radially distributed with the center point of the air inlet cross-section as the origin, so as to evenly guide the drying air flow to the surface of the cleaning member.

[0018] In some embodiments, the drying air flow enters the flow guide through the air inlet cross-section of the flow guide. The grille vanes are divided into proximal grille vanes close to the center point of the air inlet cross-section and distal grille vanes far from the center point of the air inlet cross-section. In the length direction of the air outlet, the proximal grille vanes are radially distributed with the center point of the air inlet cross-section as the origin, and there are respectively inclined angles between the plurality of distal grille vanes and the air outlet cross-section of the air outlet, and the inclined angle gradually decreases in the direction away from the air inlet cross-section, so as to evenly guide the drying air flow to the surface of the cleaning member.

[0019] In some embodiments, the grille vanes include proximal first grille vanes, distal first grille vanes and proximal second grille vanes, wherein the length of the proximal second grille vanes is less than the lengths of the proximal first grille vanes and the distal first grille vanes, and the proximal second grille vanes are arranged between the proximal first grille vanes and / or between the proximal first grille vanes and the distal first grille vanes.

[0020] In some embodiments, the distal grille vanes further include distal second grille vanes with lengths less than those of the distal first grille vanes, and the distal second grille vanes are arranged between the distal first grille vanes.

[0021] In some embodiments, the grille vanes have a first end close to the air inlet cross-section and a second end close to the air outlet cross-section. The distances between the first ends of the proximal first grille vanes and the distal first grille vanes and the air outlet cross-section are longer than the distances between the first ends of the proximal second grille vanes and the distal second grille vanes and the air outlet cross-section, so as to perform two-stage diversion on the drying air flow in step S2 and guide it to the cleaning member.

[0022] In some embodiments, each grille vane is arranged such that the distance between the second end and the air outlet cross-section is the same.

[0023] In a second aspect of the present invention, a self - moving robot system is provided, and the self - moving robot system is capable of performing the above - mentioned cleaning member drying method.

[0024] A blowing device is provided on the base station. The blowing device includes any device capable of heating and conveying air to generate a drying air flow. At the same time, the blowing device further includes a connection structure. When the self - moving robot docks to the base station, the connection structure can be connected to the air duct structure formed inside the self - moving robot to convey the drying air flow through the air duct structure to the cleaning member and dry the cleaning member.

[0025] In this drying method, by using the air duct structure formed inside the self - moving robot, it is possible to make it so that in the base station, only by setting a blowing device capable of being connected to the air duct structure of the self - moving robot, the drying air flow can be guided to blow on the cleaning member and dry the cleaning member. Compared with the prior art method of using an external air duct structure provided in the base station for drying, the drying method provided by the present invention can, while ensuring the drying effect, avoid setting a drying air duct that occupies extra space in the base station, thereby reducing the floor space occupied by the base station of the self - moving robot implementing this drying method. Therefore, the cleaning member drying method for the self - moving robot provided by the present invention can, while achieving the drying effect, save the external space occupied by the self - moving robot system, especially the base station therein.

[0034] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but in appropriate cases, the technologies, methods, and devices should be regarded as part of the specification.

[0035] To solve the above technical problems, a first aspect of the present invention provides a method for drying a cleaning part of a self - moving robot, which includes the following steps: S1. The self - moving robot docks to a base station; S2. The base station generates a drying air flow, and makes the drying air flow be transported to the cleaning part 1 of the self - moving robot through an air duct structure formed inside the self - moving robot to dry the cleaning part 1.

[0036] A blowing device is provided on the base station. The blowing device includes any device capable of heating and transporting air to generate a drying air flow. At the same time, the blowing device also includes a connection structure. When the self - moving robot docks to the base station, the connection structure can be connected to the air duct structure formed inside the self - moving robot to transport the drying air flow through the air duct structure to the cleaning part 1 and dry the cleaning part 1.

[0037] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the air duct structure has an air inlet 2 and an air outlet 3 provided on the self - moving robot. The air inlet 2 is provided on the outer surface of the self - moving robot, and the air outlet 3 points to the cleaning member 1 to blow the drying air flow towards the cleaning member 1 and dry it. The air inlet 2 and the air outlet 3 can be set in any shape according to needs. For example, the shape of the air outlet 3 is set according to the area of the projection of the cleaning member 1 in the flow direction, so that the drying air flow blown out from the air outlet 3 can cover the cleaning member 1 in the length direction of the cleaning member 1, ensuring that all parts of the cleaning member 1 can be dried.

[0038] The cleaning member 1 can be any cleaning component that needs to be blown by the air flow. For example, as Figure 1 shown, a rag in the shape of a roller.

[0039] In this drying method, by using the air duct structure formed inside the self - moving robot, it is possible to guide the drying air flow to blow on the cleaning member 1 and dry the cleaning member 1 only by setting a blowing device in the base station that can be connected to the air duct structure of the self - moving robot. Compared with the prior art method of using an external air duct structure provided in the base station for drying, the drying method provided by the present invention can ensure the drying effect while not requiring an additional - space - occupying drying air duct in the base station, thereby reducing the floor space occupied by the self - moving robot base station for implementing this drying method. Therefore, the cleaning member 1 drying method for the self - moving robot provided by the present invention can save the external space occupied by the self - moving robot system, especially the base station thereof, while achieving the drying effect.

[0040] In some embodiments, the cleaning member 1 can be set to rotate freely or be driven by a motor to rotate when being blown, so that the drying air flow can blow on all parts of the cleaning member 1, preventing the situation where part of the cleaning member 1 is dried while part is still wet, and improving the drying efficiency.

[0041] In some embodiments, the drying method provided by the present invention further includes: cleaning the cleaning member 1 using the base station after step S1 and before step S2.

[0042] A cleaning device capable of cleaning the cleaning member 1 can be set in the base station. After passing through step S1, the cleaning member 1 docks in the base station, is cleaned and wetted by the cleaning device in the base station, and is blown by the drying air flow generated in the base station to be dried in step S2.

[0043] Compared with other cleaning methods, drying during the execution of the present drying method can prevent bacteria and mold from growing on the cleaning part 1 due to being wet for a long time after being cleaned, and even prevent damage. At the same time, cleaning the cleaning part 1 before blowing the drying air flow to the cleaning part 1 in step S2 can prevent the dirt on the cleaning part 1 from being blown up by the drying air flow and falling to the ground.

[0044] In some embodiments, in step S2, the air duct structure divides the drying air flow generated by the base station into multiple strands distributed along the length direction of the cleaning part 1 and guides the drying air flow to blow onto the surface of the cleaning part 1.

[0045] The air duct structure can be set to any shape capable of dividing the drying air flow. For example, it is set to be divided into multiple branch air ducts along the flow direction, and multiple air outlets 3 distributed along the length direction of the cleaning part 1 are respectively provided on the multiple branch air ducts to divide the drying air flow into multiple strands and blow it out from the multiple air outlets 3.

[0046] Through the multiple strands of blown drying air flow, multiple parts on the cleaning part 1 can be blown and dried by the drying air flow, so that the cleaning part 1 can be evenly dried, avoiding the situation that the drying air flow concentrates on drying a part of the cleaning part 1, resulting in part of the cleaning part 1 being heated and part not being dried. While improving the cleaning efficiency, it also avoids the situation that the cleaning part 1 is damaged due to local overheating.

[0047] In some embodiments, as Figure 1 , Figure 2 and Figure 3 shown, a flow guiding member 4 is formed in the air duct structure to guide the drying air flow to blow onto the surface of the cleaning part 1 in step S2.

[0048] The flow guiding member 4 can be any component provided in the air duct structure and capable of guiding the drying air flow to blow onto the surface of the cleaning part 1, so as to be able to direct the drying air flow to blow towards the cleaning part 1.

[0049] Furthermore, the flow guiding member 4 can be any component capable of guiding the drying air flow and dividing the drying air flow into multiple strands distributed along the length direction of the cleaning part 1, such as a flow guiding plate, so as to be able to evenly blow the drying air flow onto the cleaning part 1, thereby evenly drying the cleaning part 1.

[0050] In some embodiments, as Figure 1 and Figure 3 shown, the flow guiding member 4 is provided at the end of the air duct structure along the flow direction.

[0051] By arranging the flow guide member 4 at the end of the air duct structure, it is possible to make the drying air flow directly blow onto the outer surface of the cleaning member 1 after being guided and split by the flow guide member 4, avoiding the mutual influence between multiple drying air flows after splitting and guiding, and between the dried air flow after guiding and the inner wall of the air duct, resulting in the weakening of the guiding and splitting effects, thereby affecting the uniformity of the drying air flow.

[0052] In some embodiments, the air duct structure is detachably connected with a flow guide member 4 to guide the drying air flow to blow towards the surface of the cleaning member 1 in step S2.

[0053] By providing the detachable flow guide member 4, it can be ensured that the drying air flow blown out from the air outlet 3 of the air duct structure can be guided to evenly blow onto the cleaning member 1, thereby improving the drying uniformity and drying efficiency of the present drying method.

[0054] Meanwhile, the detachable flow guide member 4 with a detachable design can be installed on various air duct structures implementing the present drying method as needed. On the premise that the flow guide member 4 can guide the drying air flow, it can be designed into any shape according to the environment and can be removed at any time according to the use of the air duct structure.

[0055] In some embodiments, the flow guide member 4 can be provided with an upwardly convex arc-shaped housing so that when the flow guide member 4 is installed on the self-moving robot, a channel for the drying air flow to pass through can be formed with the outer surface of the self-moving robot.

[0056] By utilizing the surface of the self-moving robot, the flow guide member 4 does not need to have a closed housing to form a channel for the drying air flow to pass through, but forms a channel by cooperating with the outer surface of the self-moving robot, thereby reducing the space occupied by the flow guide member 4 and facilitating the design of the self-moving robot.

[0057] In some embodiments, a sealing strip can be provided at the part of the detachable flow guide member 4 that fits with the self-moving robot. The sealing strip is squeezed when the flow guide member 4 is installed on the self-moving robot, so that when a channel is formed by the cooperation of the flow guide member 4 and the outer surface of the self-moving robot, it can be ensured that the fitting part between the flow guide member 4 and the outer surface of the self-moving robot is in a sealed state, preventing the drying air flow in the formed channel from leaking from the fitting part, and further avoiding the problem that the drying air flow blowing onto the cleaning member 1 is uneven.

[0058] In some embodiments, the flow guide member 4 can be formed into a cavity with two corresponding openings. The first opening can be connected to the air outlet 3 of the air duct structure, and the second opening is directly opposite to the cleaning member 1, so that when the flow guide member 4 is connected to the air duct structure through the first opening, a channel for the air flow to pass through can be formed inside the flow guide member 4, and the drying air flow in the air duct structure can be guided to blow onto the cleaning member 1.

[0059] The cavity formed by the flow guide member 4 can form a channel for the drying air flow inside the detachable flow guide member 4 without using the outer surface of the self - moving robot, so that the flow guide member 4 can adapt to the outer surfaces of various self - moving robots.

[0060] In some embodiments, such as Figure 1 and Figure 3 shown, the flow guide member 4 is arranged as a flow guide grille, and the grille pieces 41 in the flow guide grille are arranged to extend along the flow - through direction, and an air flow channel allowing the drying air flow to pass through is formed between adjacent grille pieces 41.

[0061] When the drying air flow passes through the flow guide grille, the drying air flow enters the above - mentioned multiple air flow channels respectively and blows out from the air flow channels respectively, so as to be split into multiple strands. The flow direction of the drying air flow in the air flow channel is restricted by the grille piece 41 forming the channel to point to the cleaning member 1. The multiple grille pieces 41 are arranged adjacent to each other, so as to form the air flow channels adjacent to each other and with the outlets arranged along the length direction of the cleaning member 1, and further can divert the air flow into multiple strands of air flow distributed along the length direction of the cleaning member 1 and evenly blow to the cleaning member 1 to evenly dry the cleaning member 1.

[0062] In some embodiments, the drying air flow enters the flow guide member 4 through the air inlet cross - section of the flow guide member 4. As Figure 5 shown, along the direction away from the air inlet cross - section, the interval between adjacent grille pieces 41 gradually becomes larger.

[0063] The air inlet cross - section refers to the cross - section of the air duct structure that is arranged in front of the flow guide member 4 along the flow - through direction. When the drying air flow passes through the air inlet cross - section, the drying air flow contacts the flow guide member 4.

[0064] In some cases, to save the internal space of the self - moving robot while ensuring the cleaning efficiency of the cleaning member 1, the length of the air inlet 2 and the cross - section of the air duct structure is set to be less than the length of the cleaning member 1. When using the arrangement method in the prior art where adjacent grille pieces 41 are arranged in parallel, the action range of the drying air flow is consistent with the cross - sectional area of the internal air duct structure of the self - moving robot, resulting in more drying air flow diverted in the air flow channels formed between some grille pieces 41 close to the air inlet cross - section and less drying air flow in the air flow channels formed between some grille pieces 41 far from the air inlet cross - section. As a result, the drying air flow blown to the cleaning member 1 is uneven, causing the part of the cleaning member 1 close to the air inlet 2 to be dried while the part far from the air inlet 2 remains undried. When the situation of local uneven drying occurs, continuing to dry may cause the already dried part of the cleaning member 1 to be heated to overheat, and for some types of cleaning members 1, this part will be damaged, thereby leading to a decline in cleaning performance; if not continuing to dry, the drying efficiency will be too low.

[0065] Therefore, a flow guide member 4 is required that can evenly divide the air flow and blow it onto the cleaning member 1 so that each part of the cleaning member 1 can be dried simultaneously.

[0066] When the drying air flow contacts the grille piece 41, the grille piece 41 arranged in the flowing direction of the drying air flow collides with and blocks the drying air flow, thereby causing the drying air flow to decelerate and blow towards the cleaning member 1 along both sides of the grille piece 41. With the above arrangement in the present application, the closer the grille piece 41 is to the air inlet 2, the denser the arrangement is, and the farther away from the air inlet 2, the sparser the arrangement is. When the drying air flow blows from the air inlet 2 to the flow guide grille in the present application, the densely arranged grille pieces 41 close to the air inlet 2 will cause the drying air flow blowing onto these grille pieces 41 to decelerate due to collision with the grille pieces 41 and be deflected to blow towards both sides of this part of the grille pieces 41, that is, in the direction away from the air inlet 2. At the same time, the grille pieces 41 farther away from the air inlet 2 are relatively sparser, so that the drying air flow blowing onto this part collides less with the grille pieces 41 and is decelerated less by the grille pieces 41.

[0067] Therefore, as described above, the air volume and wind speed of the drying air flow in the air flow channels formed between the grille pieces 41 close to the air inlet 2 and the air volume and wind speed of the drying air flow in the air flow channels formed between the grille pieces 41 far away from the air inlet 2 can be balanced, so that the drying air flow can be evenly divided into multiple strands by each grille piece 41 and the cleaning member 1 can be evenly dried.

[0068] In some embodiments, as Figure 1 、 Figure 3 and Figure 5 shown, the grille pieces 41 are radially distributed and extend along the flowing direction.

[0069] By arranging the grille pieces 41 to be radially distributed, a plurality of air flow channels formed by adjacent grille pieces 41 with a relatively dense arrangement at the entrance and a relatively loose arrangement at the exit can be formed. When the drying air flow enters the flow guide member 4, even if the area of the air inlet cross-section is small, the densely arranged air flow channel entrances can ensure that the drying air flow enters each air flow channel, so that the drying air flow can be guided into multiple strands distributed along the length direction of the cleaning member 1 to be evenly deflected onto the cleaning member 1.

[0070] In some embodiments, as Figure 1 、 Figure 3 and Figure 5 shown, in the length direction of the air outlet 3, the grille pieces 41 are radially distributed with the center point of the air inlet cross-section as the origin to evenly deflect the drying air flow onto the surface of the cleaning member 1.

[0071] When the grille pieces 41 are radially distributed with the center point of the air inlet section as the origin, when the drying air flow passes through the air inlet section and meets the grille pieces 41, one end of each grille piece 41 close to the air inlet section collides with the drying air flow, causing the drying air flow to be diverted and blown to the cleaning member 1 from the air flow channels formed between adjacent grille pieces 41. The cross-sectional area of the air flow channel entrance formed by the radially arranged grille pieces 41 is small, while the cross-sectional area of the outlet is large. Thus, when the cross-sectional area of the air inlet section is smaller than that of the air outlet, the drying air flow entering the diversion member 4 from the air inlet section can be diverted to cover the larger cross-sectional area of the air outlet 3, so that it can be evenly blown to various parts of the cleaning member 1 to achieve uniform drying.

[0072] In some embodiments, as Figure 3 and Figure 5 shown, the grille pieces 41 are divided into proximal grille pieces 411 close to the center point of the air inlet section and distal grille pieces 412 far from the center point of the air inlet section. In the length direction of the air outlet 3, the proximal grille pieces 411 are radially distributed with the center point of the air inlet section as the origin, and there are inclined angles between each of the multiple distal grille pieces 412 and the air outlet cross-section of the air outlet 3. The inclined angle gradually decreases in the direction away from the air inlet section to evenly guide the drying air flow to the surface of the cleaning member 1.

[0073] The air outlet cross-section refers to the through-flow cross-section of the air outlet 3 in the air duct structure. When the drying air flow passing through the diversion member 4 passes through the air outlet cross-section, it blows out from the air duct structure.

[0074] When the air inlet section deviates from the center point in the length direction of the diversion member 4, the two distal grille pieces 412 farthest from the air inlet section are relatively far from the air inlet section. If all the grille pieces 41 are radially distributed with the center point of the air inlet section as the origin, the air flow channels formed by the above two distal grille pieces 412 will be partially blocked by other distal grille pieces 412, thus being affected, resulting in a reduction in the air volume of the drying air flow received therein. When all the distal grille pieces 412 point to the center point of the air inlet section, only by adjusting the length of the distal grille pieces 412 can the air volume of the drying air flow in each air flow channel be balanced. However, the distal grille pieces 412 arranged as above can adjust the angle of their inclined angles within a certain range, enabling those skilled in the art to ensure that the air volume and speed of the drying air flow in the air flow channels formed by all adjacent distal grille pieces 412 are basically the same by adjusting the inclined angle, and further ensuring that the drying air flow can be evenly blown to the cleaning member 1.

[0075] Although the flow guide member 4 set in the above manner can preferably guide the drying air flow uniformly onto the cleaning member 1, in some cases, for example, when the ratio of the cross-sectional area of the air outlet to that of the air inlet is relatively large, in order to achieve a uniform effect, a large number of grid sheets 41 need to be provided to form a large number of air flow channels. When the drying air flow moves in the air flow channels, it will be subject to the frictional resistance in the air flow channels, thus reducing the speed, and further slowing down the speed of the drying air flow guided onto the cleaning member 1, resulting in a reduction in drying efficiency.

[0076] To solve the above problems, in some embodiments, as Figure 5 shown, the grid sheet 41 includes a proximal first grid sheet 4111, a distal first grid sheet 4121, and a proximal second grid sheet 4112. The length of the proximal second grid sheet 4112 is less than that of the proximal first grid sheet 4111 and the distal first grid sheet 4121. The proximal second grid sheet 4112 is disposed between the proximal first grid sheets 4111 and / or between the proximal first grid sheet 4111 and the distal first grid sheet 4121.

[0077] The air flow channels formed between adjacent proximal first grid sheets 4111, between adjacent distal first grid sheets 4121, and between adjacent proximal first grid sheets 4111 and distal first grid sheets 4121 are first air flow channels. The proximal second grid sheet 4112 is disposed between the above-mentioned first air flow channels to form a second air flow channel with the adjacent grid sheets 41. Since the second air flow channel includes the proximal second grid sheet 4112 which is shorter in length than the proximal first grid sheet 4111 and the distal first grid sheet 4121, the second air flow channel formed by the proximal second grid sheet 4112 and the adjacent grid sheets 41 is shorter in length in the air flow direction than the first air flow channel formed by the proximal first grid sheet 4111 and the distal first grid sheet 4121.

[0078] One or more proximal second grid sheets 4112 can be provided in a first air flow channel to form one or more second air flow channels with the adjacent grid sheets 41 within the first air flow channel. In the first air flow channel, the proximal second grid sheet 4112 can also not be provided to form a first air flow channel that does not include a second air flow channel.

[0079] When the drying air flow enters the flow guide member 4 and contacts the grid sheet 41, the drying air flow enters the first air flow channel and the second air flow channel. By adjusting the number and positions of the proximal second grid sheets 4112 in each first air flow channel, the drying air flow in the first air flow channel can be finely divided and guided, so that the flow guide member 4 can uniformly guide the drying air flow onto the cleaning member 1.

[0080] With respect to the grid pieces 41 of the same set length, an air flow channel of the same length in the air flow direction is formed. In the setting mode of the first air flow channel and the second air flow channel in the present application, by setting the second air flow channel with a shorter length in the air flow direction, the time of the drying air flow in the air flow channel formed by the grid pieces 41 can be reduced while ensuring the diversion effect, thereby reducing the frictional resistance along the air flow channel, and further increasing the speed of the drying air flow blown out from the flow guiding member 4 to improve the drying effect.

[0081] In some embodiments, the distal grid piece 412 further includes a distal second grid piece with a length less than that of the distal first grid piece 4121, and the distal second grid piece is arranged between the distal first grid pieces 4121.

[0082] When the air volume and air speed of the drying air flow flowing into the first air flow channel formed between the distal first grid pieces 4121 are high enough, one or more distal second grid pieces can be set to form one or more second air flow channels between the first air flow channels.

[0083] Through the second air flow channel, the drying air flow can be diverted and split again in the first air flow channel formed by the distal first grid pieces 4121, so as to evenly blow the drying air flow to the cleaning member 1.

[0084] In the first air flow channel, one or more proximal second grid pieces 4112 or distal second grid pieces can be set to slow down the air speed in the first air flow channel by arranging a plurality of second air flow channels therein.

[0085] In the first air flow channel with a relatively low air speed, the proximal second grid piece 4112 or the distal second grid piece may not be set to prevent the increased proximal second grid piece 4112 or distal second grid piece from forming a second air flow channel and reducing the air speed in the first air flow channel.

[0086] Through the above settings, by setting fewer first air flow channels, the drying air flow can be first split, and then the air speed and direction of the drying air flow in the first air flow channel can be adjusted by arranging a plurality of second air flow channels.

[0087] Compared with the air flow channel that can cover the whole process from the air inlet section to the air outlet 3 along the air flow direction, the above setting mode reduces the frictional resistance of the air flow channel formed by the grid pieces 41 to the drying air flow by setting the second air flow channel with a shorter length, so that the speed of the drying air flow when blowing on the cleaning member 1 is higher, and the drying efficiency is improved.

[0088] The way of simultaneously setting the first air flow channel and the second air flow channel also provides more adjustment space for the design of the diversion grille. By adjusting the number and position of the second air flow channels, the wind speed and air volume of the drying air flow blown out from each air flow channel can be adjusted, so that the drying air flow can blow onto the cleaning member 1 more evenly.

[0089] In some embodiments, as Figure 5 shown, the grille piece 41 has a first end close to the air inlet section and a second end close to the air outlet section. The distance between the first end of the proximal first grille piece 4111 and the distal first grille piece 4121 and the air outlet section is longer than the distance between the first end of the proximal second grille piece 4112 and the distal second grille piece and the air outlet section, so as to perform two-stage diversion on the drying air flow in step S2 and guide it onto the cleaning member 1.

[0090] Through the above settings, the inlet of the first air flow channel is formed by the first ends of the adjacent proximal first grille piece 4111 and the distal first grille piece 4121. The first ends of the proximal second grille piece 4112 and the distal second grille piece and the adjacent grille piece 41 form the inlet of the second air flow channel. Since the first ends of the proximal first grille piece 4111 and the distal first grille piece 4121 are closer to the air inlet section than the first ends of the proximal second grille piece 4112 and the distal second grille piece, this first air flow channel has a first air flow channel inlet closer to the air inlet section.

[0091] During use, the drying air flow enters the first air flow channel and the second air flow channel formed in the diversion grille through the air inlet section and is diverted to blow onto the cleaning member 1. Since the first air flow channel has a first air flow channel inlet closer to the air inlet section, it can first receive the drying air flow in the air inlet section and perform the first-stage diversion on the drying air flow. The drying air flow continues to move in the original direction in the first air flow channel and enters the second air flow channel for secondary diversion, and finally is blown out from the outlet of the second air flow channel onto the cleaning member 1.

[0092] The first-stage diversion of the first air flow channel can divert the gas when the air flow blows out from the air inlet section, so that the drying air flow can be evenly diverted to multiple first air flow channels, while ensuring that the number of grille pieces 41 is small, so that the drying air flow will not lose too much speed when being first-stage diverted. The second-stage diversion of the second air flow channel can perform secondary diversion on the drying air flow diverted into the first air flow channel to divert the drying air flow into drying air flows with the same air volume and wind speed in each second air flow channel. By adjusting the interval size between the proximal first grille piece 4111 and the proximal second grille piece 4112 forming the second air flow channel, the proportion of the drying air flow in the first air flow channel entering each second air flow channel and the speed of the drying air flow in the second air flow channel can be adjusted, so as to ensure that the air flow blows evenly onto the cleaning member 1.

[0093] In some embodiments, as Figure 5 shown, the distance between the second end of each grille piece 41 and the air outlet section is set to be the same.

[0094] The second ends of the grille pieces 41 with equal distances from the air outlet section will form the outlets of multiple first air flow channels and second air flow channels, so that the distances between the outlets of each first air flow channel and second air flow channel and the air outlet section are equal, so that the air flows blown out from the first air flow channel and the second air flow channel are blown out at positions with the same distance relative to the cleaning member 1.

[0095] By unifying the positions where the drying air flow is blown out from the above-mentioned first air flow channel and second air flow channel, the interference between the drying air flows blown out from each air flow channel can be reduced, thereby preventing the interference between multiple drying air flows, resulting in a decrease in the wind speed of the drying air flow or even uneven distribution.

[0096] In some embodiments, as Figure 5 shown, the second end of each grille piece 41 is set to extend to the air outlet section.

[0097] By setting as above, the outlets of the first air flow channel and the second air flow channel can coincide with the air outlet section, that is, the drying air flow passing through the flow guiding member 4 can directly blow onto the cleaning member 1. By shortening the distance between the outlets of the first air flow channel and the second air flow channel and the cleaning member 1, after the drying air flow is diverted into multiple strands distributed along the length direction of the cleaning member 1, it can immediately blow onto the cleaning member 1. When the distance between the outlets of the first air flow channel and the second air flow channel and the cleaning member 1 is too far, some of the drying air flow that has been diverted and guided will blow from both sides of the air outlet 3 to both sides of the cleaning member 1 instead of onto the cleaning member 1, resulting in waste, and the above-mentioned setting method can avoid this problem, thereby improving the utilization rate of the drying air flow and further improving the drying efficiency.

[0098] The cleaning member drying method provided by the present application for the self - moving robot can dry the cleaning member 1 on the self - moving robot without setting an external air duct in the base station compared with the prior art using an external air duct in the base station, so that the self - moving robot base station implementing this drying method can not set an external air duct, thereby having a smaller floor area.

[0099] The second aspect of the present invention provides a self - moving robot system, which can execute the above - mentioned cleaning member drying method.

[0100] The self - moving robot system includes a base station and a self - moving robot. An air duct structure is formed inside the self - moving robot. The base station includes a blowing device that can be connected to the air duct structure therein when the self - moving robot docks at the base station. The blowing device is provided with a heating device and an air driving device, so as to be able to generate a drying air flow.

[0101] The above - mentioned self - moving robot system can execute the cleaning part drying method for the self - moving robot in this application to dry the cleaning part 1 provided on the self - moving robot. Specifically, when drying, first perform step S1 until the self - moving robot docks at the base station and is in a docked state, and then perform step S2. The blowing device in the base station is connected to the air duct structure in the self - moving robot, and conveys the drying air flow to the cleaning part 1 to dry the cleaning part 1.

[0102] This self - moving robot system can execute the above - mentioned cleaning part drying method for the self - moving robot. Therefore, without setting an external pipeline and air guiding device, the generated drying air flow can be blown onto the cleaning part 1 on the self - moving robot. Compared with the existing self - moving robot systems, especially the base stations therein, it has the advantage of smaller floor area.

[0103] In some embodiments, a flow guiding member 4 is provided in the air duct structure inside the self - moving robot, and the flow guiding member 4 is set as a flow guiding grille. Through the above setting, after the drying air flow enters the flow guiding member 4, it can be guided by the grille vanes 41 into multiple air flows distributed along the length of the cleaning part 1.

[0104] Preferably, the flow guiding grille is set such that in the direction away from the air inlet 2 of the air duct structure, the interval between adjacent grille vanes 41 becomes larger. The closer the grille vanes 41 are arranged, the stronger the deceleration effect on the drying air flow; the looser the arrangement, the weaker the deceleration effect on the drying air flow. The closer to the air inlet 2, the higher the wind speed of the drying air flow, and the farther from the air inlet, the lower the wind speed of the drying air flow. Through the above - set grille vanes 41, the wind speeds of the drying air flows at various positions in the flow guiding member 4 can be balanced, so that the wind speeds of the multiple drying air flows blowing onto the cleaning part 1 are basically the same, thereby being able to dry the cleaning part 1 evenly and improve the drying efficiency.

[0105] In summary, this self - moving robot system can execute the above - mentioned drying method for the sweeping robot and can use the structure arranged in the above - mentioned drying method. The base station without an external air duct can evenly guide the drying air flow onto the cleaning part 1 and dry the cleaning part 1. The base station therein occupies less space because it does not need to set an external air duct.
