Description

Technical Field

[0001] This disclosure relates to a surface cleaning system and a control method for the surface cleaning system. Background Technology

[0002] Existing floor scrubbers can clean surfaces by using hot water and have excellent cleaning results.

[0003] After cleaning the surface, the roller brush of this floor scrubber will have dirt on it. Therefore, it is necessary to clean the roller brush in time to prevent it from producing odors and affecting the user experience.

[0004] Moreover, existing floor scrubbers, such as the Chinese invention patent publication document CN114376484A, disclose a roller brush drying method, device and cleaning equipment, which dries the roller brush after the roller brush has self-cleaned.

[0005] However, existing floor scrubbers require the power of the cleaning equipment's battery for both self-cleaning and drying. This causes battery wear and tear and also prolongs the charging time of the floor scrubber. In other words, if the floor scrubber is not charged in time after self-cleaning and drying, it will also affect the running time of the floor scrubber. Summary of the Invention

Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0074] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0075] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0076] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0077] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well.

It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0078] Figure 1 This is a schematic diagram of the structure of a surface cleaning device 100 according to one embodiment of the present disclosure.

[0079] The surface cleaning system may include a surface cleaning device 100 and a base station 200 for docking the surface cleaning device 100.

[0080] The surface cleaning device 100 is used to clean the surface to be cleaned. Preferably, the surface cleaning device 100 is capable of wet cleaning the surface to be cleaned and recovering the liquid after cleaning the surface to be cleaned back to the surface cleaning device 100.

[0081] In one embodiment, the surface cleaning device 100 can clean the surface to be cleaned by frictional contact between the agitator 150 and the surface to be cleaned, and during the frictional contact between the agitator 150 and the surface to be cleaned, cleaning liquid can be provided to the agitator 150 or the surface to be cleaned near the agitator 150, thereby achieving wet cleaning of the surface to be cleaned.

[0082] In this disclosure, the surface cleaning device may include components such as a fluid distribution system 110 and a fluid recovery system 120.

[0083] Specifically, the fluid distribution system 110 is used to store cleaning liquid and is capable of distributing the stored cleaning liquid to the agitator 150 or a surface to be cleaned in the vicinity of the agitator 150. For example, the fluid distribution system 110 includes a distribution channel 111, a nozzle 112, and a supply tank 113, the supply tank 113 and the nozzle 112 at least partially defining the distribution channel 111.

[0084] In this disclosure, the supply tank 113 is formed in the shape of a box to store cleaning liquid within the supply tank 113. In one embodiment, the cleaning liquid may be a liquid such as purified water or a mixture of water and cleaning agent.

[0085] The dispensing channel 111 is connected to the supply tank 113 and the nozzle 112 to provide cleaning liquid in the supply tank 113 to the nozzle 112. In one embodiment, a pump may be provided on the dispensing channel 111 so that the cleaning liquid in the supply tank 113 is provided to the nozzle 112 after being pressurized. Further, the nozzle 112 provides the cleaning liquid to the agitator 150 or to the surface to be cleaned near the agitator 150.

[0086] In one embodiment, the surface cleaning device 100 may further include a frame portion 130 and a cleaning portion 140, the cleaning portion 140 being pivotally connected to the frame portion 130, wherein the agitator 150 is formed as part of the cleaning portion 140, and correspondingly, the cleaning portion 140 may further include a drive component for driving the agitator 150 to rotate, etc., which will not be described in detail here.

[0087] The cleaning section 140 includes a removable cover 141, the cleaning section 140 having a receiving cavity, the inner surface of the cover 141 being formed as a substantially smooth surface, and the inner surface of the cover 141 forming at least a portion of the sidewall of the receiving cavity.

[0088] The supply tank 113 can be disposed inside the frame portion 130, and the cleaning liquid of the supply tank 113 can be injected through the interface provided on the frame portion 130.

[0089] Accordingly, the nozzle 112 is disposed in the cleaning section 140 and close to the stirrer 150. At this time, a portion of the dispensing channel 111 is located in the frame section 130 and another portion is located in the cleaning section 140.

[0090] The fluid recovery system 120 includes a recovery channel 121, a suction nozzle 122, and a recovery tank 123, the recovery tank 123 and the suction nozzle 122 at least partially defining the recovery channel 121.

[0091] In one embodiment, the suction nozzle 122 may be disposed in the cleaning section 140 and located behind the agitator 150 to facilitate the collection of wastewater after the agitator 150 has cleaned the surface to be cleaned.

[0092] The recycling channel 121 is partially located in the cleaning section 140 and partially in the frame section 130, and the recycling tank 123 is located in the frame section 130. For example, the frame section 130 forms a receiving space, and the recycling tank 123 is detachably disposed in the frame section 130 so that when the recycling tank 123 contains a large amount of liquid, the user can remove the recycling tank 123, pour out the wastewater, and clean up the solid waste inside.

[0093] In this disclosure, the surface cleaning device 100 further includes a first airflow accelerator 160, which is in fluid communication with the fluid recovery system 120 to force the flow of gas within the recovery channel 121. In one embodiment, the first airflow accelerator 160 can be a suction device capable of generating a negative pressure that can be applied to the recovery tank 123, thereby allowing gas to flow from the suction nozzle 122 to the recovery tank 123, and consequently causing wastewater to flow in the same direction. More preferably, the first airflow accelerator 160 is in fluid communication with the suction nozzle 122 to generate working gas flowing through the recovery path in the self-cleaning cycle.

[0094] In this disclosure, the agitator 150 is disposed in the receiving cavity of the cleaning section and is located in the fluid distribution system 110 and the fluid recovery system 120, and the rotation axis of the agitator 150 is arranged laterally close to the suction nozzle 122; thereby, the surface to be cleaned can be cleaned by the agitator 150 and the cleaning liquid after cleaning the surface to be cleaned can be recovered.

[0095] In this disclosure, the base station 200 may include a heating system 210, which includes a heating channel 211, a channel inlet 212, a channel outlet 213, and a heater 214. The channel inlet 212 and the channel outlet 213 at least partially define the heating channel 211, and the heater 214 is provided in the heating channel 211. Thus, the fluid in the heating channel 211 can be heated by the heater 214.

[0096] In one embodiment, the base station 200 further includes a second airflow accelerator 220, which is in fluid communication with the heating system 210 and forces fluid flow within the heating channel 211. In one embodiment, the second airflow accelerator 220 may be a component such as a fan.

[0097] In one embodiment, when the surface cleaning device 100 is disposed on the base station 200, the stirrer 150 is disposed on the heating system 210, thereby enabling the stirrer 150 to be dried by the heating system 210.

[0098] The surface cleaning system includes a controller 170, which can be a component of the surface cleaning device 100 or a component of the base station 200. In the embodiments of this disclosure, the controller 170 is a component of the surface cleaning device 100. Furthermore, when the surface cleaning device 100 is docked at the base station 200, a communication connection can be established between the surface cleaning device 100 and the base station 200. Therefore, the controller 170 can control not only the first airflow accelerator 160, but also the second airflow accelerator 220 and the stirrer 150. In one embodiment, the controller 170 can be an embedded controller, such as a microcontroller or a DSP.

[0099] The surface cleaning device 100 may also include a rechargeable battery 180, which is used to selectively power the surface cleaning system; for example, the rechargeable battery 180 can power components of the surface cleaning device 100 that require electrical energy, such as the controller 170, the first airflow accelerator 160, the agitator 150, and the pump.

[0100] In this disclosure, the controller 170 is configured to perform a heat drying cycle after performing at least one self-cleaning cycle. During the self-cleaning cycle, cleaning liquid stored in the supply tank 113 is supplied to the stirrer 150 through the nozzle 112. The stirrer 150 rotates about its axis in a first direction. After the self-cleaning cycle ends, the cleaning liquid near the stirrer 150 is recovered to the recovery tank 123 through the suction nozzle 122. During the heat drying cycle, the stirrer 150 rotates about its axis in at least a second direction, the first direction being opposite to the direction of rotation of the second direction. During the self-cleaning cycle and / or the heat drying cycle, the charging circuit of the rechargeable battery 180 remains at least active.

[0101] When the stirrer 150 rotates in the second direction, the stirrer 150 maintains an interference fit with the substantially smooth inner surface of the cover 141 so that the inner surface of the cover 141 forms a reverse interference with the fuzz on the outer peripheral surface of the stirrer 150, changing the orientation of the fuzz on the outer peripheral surface of the stirrer 150, thereby enabling the fuzz of the stirrer 150 (brush) to be dried more thoroughly.

[0102] Therefore, the surface cleaning device 100 of this disclosure can remain in a charging state for a long time, or even charge continuously, when docked at a base station for maintenance. Thus, when the user has not finished cleaning the surface to be cleaned, and the agitator 150 is dirty and needs cleaning, the surface cleaning device 100 can be used again with a longer battery life.

[0103] Specifically, when the self-cleaning cycle switches to the hot drying cycle, the charging circuit of the rechargeable battery 180 is activated, thereby continuously charging the rechargeable battery during the heat treatment process of the stirrer 150 by the surface cleaning device 100.

[0104] In one implementation, the controller 170 is configured to: initiate the rotation of the stirrer 150 about its rotation axis in a second direction at the start of the hot drying cycle; initiate the rotation of the stirrer 150 about its rotation axis in the second direction before the end of the hot drying cycle; and initiate the rotation of the stirrer 150 in a first direction and a second direction respectively during the end of the hot drying cycle.

[0105] More preferably, during the end of the hot drying cycle, the stirrer 150 rotates in the second direction for a longer time than it rotates in the first direction, thereby making the fluff of the stirrer 150 of this disclosure softer.

[0106] In this disclosure, during the hot drying cycle, the power of the first airflow accelerator 160 is reduced to 0; that is, the first airflow accelerator 160 is controlled to stop working, so that hot air will not enter the recovery channel 121 and the recovery tank 123 after the drying agitator 150, thereby not affecting components such as the recovery tank 123.

[0107] In one implementation, the charging circuit of the rechargeable battery 180 remains disabled during the heat drying cycle.

[0108] In another implementation, during the hot drying cycle, the heating system 210 is powered by mains electricity, and the charging circuit of the rechargeable battery 180 is activated.

[0109] According to another aspect of this disclosure, a control method for a surface cleaning system is provided, wherein the surface cleaning system can be the surface cleaning system described above, and the structure of the surface cleaning system will not be described in detail here.

[0110] The control method of the surface cleaning system includes: the surface cleaning device 100 receiving a heat treatment signal to heat-treat the agitator 150 of the surface cleaning device 100; and based on the heat treatment signal, the controller 170 of the surface cleaning device 100 executes at least one self-cleaning cycle and one heat drying cycle; wherein, in the execution of the self-cleaning cycle, the cleaning liquid stored in the supply tank 113 is supplied to the agitator 150 through the nozzle 112, the agitator 150 rotates about its rotation axis in a first direction, and after the self-cleaning cycle ends, the cleaning liquid near the agitator 150 is recovered to the recovery tank 123 through the suction nozzle 122; in the execution of one heat drying cycle, the agitator 150 rotates about its rotation axis in at least a second direction, the first direction being opposite to the rotation direction of the second direction; and in the self-cleaning cycle and / or the heat drying cycle, the charging circuit of the rechargeable battery 180 remains at least active.

[0111] When the stirrer 150 rotates in the second direction, the stirrer 150 maintains an interference fit with the substantially smooth inner surface of the cover 141 so that the inner surface of the cover 141 forms a reverse interference with the fuzz on the outer peripheral surface of the stirrer 150, changing the orientation of the fuzz on the outer peripheral surface of the stirrer 150, thereby enabling the fuzz of the stirrer 150 (brush) to be dried more thoroughly.

[0112] In this disclosure, a heat treatment signal can be generated by triggering the self-cleaning button of the surface cleaning device 100. Alternatively, a heat treatment signal can be generated by triggering the virtual button of an APP installed on a mobile phone or other smart device. After receiving the heat treatment signal, the surface cleaning device 100 determines that the state of the surface cleaning device and the base station meets the requirements for heat treatment, that is, the stirrer 150 of the surface cleaning device 100 can be heat treated.

[0113] When heat-treating the agitator 150 of the surface cleaning device 100, the controller 170 of the surface cleaning device 100 executes at least one self-cleaning cycle and one hot drying cycle; in one embodiment, during the heat treatment of the agitator 150, only one self-cleaning cycle and one hot drying cycle may be executed. Of course, the self-cleaning cycle may be executed multiple times, but the hot drying cycle only needs to be executed once.

[0114] In one implementation, the controller 170 is configured to: initiate the rotation of the stirrer 150 about its rotation axis in a second direction at the start of the hot drying cycle; initiate the rotation of the stirrer 150 about its rotation axis in the second direction before the end of the hot drying cycle; and initiate the rotation of the stirrer 150 in a first direction and a second direction respectively during the end of the hot drying cycle.

[0115] More preferably, during the end of the hot drying cycle, the stirrer 150 rotates in the second direction for a longer period than it rotates in the first direction.

[0116] In this disclosure, during the hot drying cycle, the power of the first airflow accelerator 160 is reduced to 0; that is, the first airflow accelerator 160 is controlled to stop working, so that hot air will not enter the recovery channel 121 and the recovery tank 123 after the drying agitator 150, thereby not affecting components such as the recovery tank 123.

[0117] In one implementation, the charging circuit of the rechargeable battery 180 remains disabled during the heat drying cycle.

[0118] In another implementation, during the hot drying cycle, the heating system 210 is powered by mains electricity, and the charging circuit of the rechargeable battery 180 is activated.
