Referring to fig. 7, the control unit 30 of the surface cleaning system of the present application comprises two parts, one part being located within the surface cleaning apparatus 10, namely a first controller 301 located within the surface cleaning apparatus 10; a second controller 302, a part of which is located in the base station apparatus 20, that is, in the base station apparatus 20; the two controllers will effect control of the operation of the various controllable components on the surface cleaning system; in this example, the first controller 301 in the surface cleaning apparatus 10 can control whether the suction motor 42, the pump 33, and the brushroll motor 16 are engaged; the second controller 302 in the base station apparatus 20 can control whether the heat generating core 82 participates in the operation, and control the operation of the temperature indicating module (if any) and the status display lamp (if any). In other embodiments, the control unit of the surface cleaning system may be integrated into the surface cleaning apparatus, and according to this scheme, the heating core in the base station apparatus also controls the control unit in the surface cleaning apparatus; for this reason, the surface cleaning apparatus and the base station apparatus construct a path for instruction transmission after docking.

The brush rolls 14 are positioned at the recesses 6 during parking of the surface cleaning apparatus 10 in the base station apparatus 20. At this time, the surface cleaning system can perform a self-cleaning, sterilizing and drying process for the surface cleaning apparatus under the control of the control unit 30, specifically: during the time when the surface cleaning device 10 is parked in the base station device 20, the brush roller is subjected to a self-cleaning process of cleaning with water, a sterilization process of sterilizing the brush roller with steam, and a drying process of drying the brush roller with hot air; of course, the self-cleaning process, the sterilization process, and the drying process are also directed to the recovery flow path of the surface cleaning apparatus.

As shown in fig. 8, the self-cleaning process, the sterilization process, and the drying process of this example are configured to be sequentially performed in this order; thus, the user only needs to interact with the surface cleaning system once, and the program comprising the processes is triggered, so that the self-cleaning process, the sterilization process and the drying process are sequentially carried out; user interaction with the surface cleaning system may be achieved by activating a program switch disposed on the surface cleaning apparatus or on the base station apparatus; in other embodiments, the user interaction with the surface cleaning system may be omitted by monitoring whether the surface cleaning device is parked at the base station by a monitoring device, and automatically performing the self-cleaning process, the sterilization process, and the drying process when the surface cleaning device is parked at the base station.

In other possible embodiments, the sterilization process or the drying process may be set as a program for the user to individually select execution.

As shown in fig. 9, the self-cleaning process of this example includes the following stages in sequence:

an immersion cleaning stage: first, water is continuously supplied to brushroll 14 via water tank 31 for a period of time, at which time suction motor 42 is not activated; in the step, water which is not absorbed by the brush roller 14 falls into the groove 6, water is supplied continuously until a sufficient amount of water is collected in the groove 6, and the water in the groove 6 is heated continuously by the heating wall 8 in the groove 6 to become hot water with temperature; secondly, stopping supplying water, and continuously rotating the brush roller 14 for a period of time, wherein the brush roller 14 is at least partially immersed in the hot water in the groove 6, and the continuous rotation of the brush roller 14 can realize immersion cleaning of the brush roller 14; again, the suction motor 42 is turned on and the brush roller 14 is kept rotating to effect transfer of the immersion-cleaned water from the trough 6 to the dirty liquid recovery tank 41 via the recovery flow path 43.

A spraying type cleaning stage: supplying water to the brush roller 14 again through the water tank 31, turning on the suction motor 42 and driving the brush roller 14 to rotate, and transferring the liquid falling from the brush roller 14 to the dirty liquid recovery tank 41 through the recovery flow path 43; in this step, "new" water is continuously distributed to the brush roller 14, and at the same time, "old" water falling from the brush roller 14 is transferred to the dirty liquid recovery tank 41 via the recovery flow path 43; continued rotation of brush roll 14 may enable spray cleaning of brush roll 14.

A spin-drying stage: the water supply is stopped, suction motor 42 is turned on and brushroll 14 is driven to rotate for a period of time to spin dry the water on brushroll 14 as much as possible.

And after the above stages are sequentially finished, the whole self-cleaning treatment process is finished.

In the embodiment, in the self-cleaning treatment, the immersion type cleaning stage and the spraying type cleaning stage of the brush roller can be alternatively performed, such as only one spraying type cleaning stage is performed; in other embodiments, the heating body in the groove can be used for immersion cleaning or spray cleaning of the brush roller by using normal-temperature water instead of heating; in addition, in some possible embodiments, the water used in the self-cleaning process may also come from outside the tank, such as from a water reservoir on the base unit, or even from a water supply line interfaced with the base unit. The purpose of the self-cleaning process is to clean the brush roll, and any solution that facilitates cleaning of the brush roll may be used herein.

The sterilization treatment of this embodiment is performed after the self-cleaning treatment is completed, and the purpose of the sterilization treatment is to sterilize the brush roller after cleaning with steam. In the sterilization process, the steam used is generated by the heating wall 8 heating the water flowing into the recess 6, which may be the water supplied to the brush roller 14 via the water tank 31 or from elsewhere. In the sterilization process, in order to instantaneously generate a large amount of steam and increase the temperature of the steam, the amount of water supplied to the brush roller during this process should be reduced relative to the amount of water for the self-cleaning process.

In embodiments thereof, the sterilization process may also be eliminated or incorporated into the self-cleaning process.

The drying process of this example, which is performed after the self-cleaning process or the sterilization process (if any) is finished, is intended to further dry the brush roller to prevent generation of an offensive odor or mildew at a later stage. In the drying process, the suction motor 42 is started, the heating wall 8 works to generate heat, and the brush roller 14 rotates at a constant speed; under the action of the heat-generating wall 8 and the suction motor 42, the air flowing through the groove 6 is heated into hot air by the heat-generating wall 8, and the hot air flowing towards the recovery flow path 43 quickly takes away the moisture on the brush roller 14 when passing through the brush roller 14, so that the effect of quickly drying the brush roller is achieved, and meanwhile, the hot air also quickly takes away the moisture remaining in the heat recovery flow path 43 when flowing through the recovery flow path 43.

In the drying process of the present application, the hot air used for drying is generated by the heating wall 8 heating the air flowing through the groove 6, the flowing power of the hot air coming from the suction motor 42. Compared with the traditional method that the hot air generated by the fan or the fan combined heating assembly is used for drying the brush roller, the hot air temperature can be higher, the flowing speed of the hot air can be higher, so that the heat exchange at the groove is more violent, more heat can be transferred to the brush roller through the heat convection between the flowing hot air and the brush roller 14, and the brush roller can be dried more quickly through the radiation heat exchange between the heating wall 8 and the brush roller 14.

The above embodiments are merely illustrative of the technical concepts and features of the present application, and the purpose of the present invention is to enable those skilled in the art to understand the content of the present application and implement the present application, and not to limit the protection scope of the present application. All equivalent changes or modifications made according to the spirit of the present application should be covered within the protection scope of the present application.
