Description

Base station, surface cleaning system and cleaning, drying and disinfecting method of surface cleaning equipment

Technical Field

The present disclosure relates to a base station, a surface cleaning system, and a cleaning, drying, and disinfecting method for a surface cleaning apparatus.

Background

Current surface cleaning devices can typically be used to wet scrub clean hard floors or short hair carpets. Such devices typically have one or more roller brushes or cleaning plates made of wool material. The tough soil on the floor can be scrubbed by adding water or a water/detergent mixture. As the machine moves over the dirt, the dirt which has been wiped off by the roller brush and dissolved by the water or water/detergent mixture is sucked up by the cleaning heads arranged in the direction of movement of the roller brush, in the technique of providing the cleaning disc, the cleaning heads may not be provided and the dirt is directly sucked up by the cleaning material on the cleaning disc.

However, tough soils are often difficult to clean and, after the soil has been scattered on the floor surface, evaporation of water can form tough soils on the surface that are difficult to remove. Typically, not all of these tough soils are removed by the cleaning operation during scrubbing, and therefore some of the soil remains on the floor, reducing the quality of the cleaning.

In order to improve the cleaning quality, cleaning is usually performed by mixing a cleaning agent and water, mixing the cleaning agent and water in a cleaning water tank of a surface cleaning device according to a certain proportion to form a cleaning fluid, and then applying the cleaning fluid to a rolling brush or a cleaning disc to achieve a good cleaning effect of stubborn dirt. This means, however, that the control of the proportion of the cleaning agent also has to be carried out exclusively for the cleaning process of the cleaning agent and that it is not necessary to apply this cleaning agent everywhere on the cleaning surface, in such a way that this leads to an increase in time and costs.

Another way is to implement steam treatment, in which a hot steam generating device is arranged in the surface cleaning device, when cleaning specific stubborn dirt, the atomization heating device of the surface cleaning device carries out steam treatment on water in the clean water tank by inputting control signals, and the water is sprayed to a rolling brush or a cleaning disc, especially to clean the surface, so as to soften the stubborn dirt and lead the stubborn dirt to be separated from the surface, thereby achieving the cleaning purpose. However, the steam of the surface cleaning apparatus is not easy to control, often greatly consumes the cruising ability of the surface cleaning apparatus, and during the steam implementation process, extra steam which is not desired by the user is often generated, and the user experience is poor.

The existing surface cleaning device, whether it is an autonomous mobile cleaning device or a handheld cleaning device, has a limited volume of a cleaning tank carried by itself due to natural limitations of its structure and volume, and requires frequent replacement of cleaning water in a large-area situation, especially when the cleaning device is stained as described above, and has a short duration, which brings about a decline in experience, so a technology capable of solving the above-described problems is needed.

Detailed Description

The present disclosure is described in further detail below with reference to the drawings and the embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant content and not limiting of the present disclosure. It should be further noted that, for convenience of description, only a portion relevant to the present disclosure is shown in the drawings.

In addition, embodiments of the present disclosure and features of the embodiments may be combined with each other without conflict. The technical aspects of the present disclosure will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.

Unless otherwise indicated, the exemplary implementations/embodiments shown are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure may be practiced. Thus, unless otherwise indicated, features of the various implementations/embodiments may be additionally combined, separated, interchanged, and/or rearranged without departing from the technical concepts of the present disclosure.

The use of cross-hatching and/or shading in the drawings is typically used to clarify the boundaries between adjacent components. As such, the presence or absence of cross-hatching or shading does not convey or represent any preference or requirement for a particular material, material property, dimension, proportion, commonality between illustrated components, and/or any other characteristic, attribute, property, etc. of a component, unless indicated. In addition, in the drawings, the size and relative sizes of elements may be exaggerated for clarity and/or descriptive purposes. While the exemplary embodiments may be variously implemented, the specific process sequences may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in reverse order from that described. Moreover, like reference numerals designate like parts.

When an element is referred to as being "on" or "over", "connected to" or "coupled to" another element, it can be directly on, connected or coupled to the other element or intervening elements may be present. However, when an element is referred to as being "directly on," "directly connected to," or "directly coupled to" another element, there are no intervening elements present. For this reason, the term "connected" may refer to physical connections, electrical connections, and the like, with or without intermediate components.

For descriptive purposes, the present disclosure may use spatially relative terms such as "under … …," under … …, "" under … …, "" lower, "" above … …, "" upper, "" above … …, "" higher "and" side (e.g., as in "sidewall"), etc., to describe one component's relationship to another (other) component as illustrated in the figures. In addition to the orientations depicted in the drawings, the spatially relative terms are intended to encompass different orientations of the device in use, operation, and/or manufacture. For example, if the device in the figures is turned over, elements described as "under" or "beneath" other elements or features would then be oriented "over" the other elements or features. Thus, the exemplary term "below" … … can encompass both an orientation of "above" and "below". Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, when the terms "comprises" and/or "comprising," and variations thereof, are used in the present specification, the presence of stated features, integers, steps, operations, elements, components, and/or groups thereof is described, but the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof is not precluded. It is also noted that, as used herein, the terms "substantially," "about," and other similar terms are used as approximation terms and not as degree terms, and as such, are used to explain the inherent deviations of measured, calculated, and/or provided values that would be recognized by one of ordinary skill in the art.

According to one embodiment of the present disclosure, a surface cleaning system is provided. Fig. 1 and 2 show schematic views of a surface cleaning system according to this embodiment.

As shown in fig. 1 and 2, surface cleaning system 10 may include a surface cleaning apparatus 100, and a base station 200. In which fig. 1 shows a case where the surface cleaning apparatus 100 and the base station 200 are combined (the surface cleaning apparatus 100 is docked to the base station 200), and fig. 2 shows a case where the surface cleaning apparatus 100 and the base station 200 are separated. As shown in fig. 1, after the surface cleaning apparatus 100 is docked to the base station 200, the surface cleaning apparatus 100 may be charged by the base station 200, and the surface cleaning apparatus 100 may also be supplied with cleaning liquid or circulated with the surface cleaning apparatus 100.

In the present disclosure, the surface cleaning apparatus 100 may be an upright surface cleaning apparatus or a horizontal surface cleaning apparatus, may be an autonomous mobile surface cleaning apparatus or a handheld surface cleaning apparatus, and may be a wired surface cleaning apparatus or a wireless surface cleaning apparatus. The type of surface cleaning apparatus is not limited in this disclosure, but will be described in this disclosure as a wireless handheld upright surface cleaning apparatus. While applicable to other types of surface cleaning apparatus, those skilled in the art will appreciate that corresponding modifications may be made based on the type of surface cleaning apparatus specifically described in the present disclosure and will not be described in detail herein.

In addition, the surface cleaning apparatus 100 may be used for cleaning floors or floor carpets, and may also be used for cleaning other objects, such as glass, etc.

As shown in fig. 1 and 2, the surface cleaning apparatus 100 may include a cleaning portion 110 and a cleaning liquid storage portion 120. The cleaning part 110 may include a cleaning brush or a cleaning tray. When the cleaning brush is included, the cleaning can be performed by rolling, and when the cleaning tray is included, the cleaning can be performed by rotating. The cleaning liquid storage part 120 may be in the form of a water tank for storing the cleaning liquid, and may transfer the cleaning liquid to the cleaning part 110 or the vicinity of the cleaning part 110, for example, the cleaning liquid stored in the cleaning liquid storage part 120 may be sprayed to the cleaning part 110 or the vicinity of the cleaning part 110 through the cleaning liquid transfer line 121.

In the present disclosure, the cleaning liquid is preferably cleaning hot water, the temperature of which is greater than or equal to the first temperature threshold. In the entire process of cleaning the surface cleaning apparatus 100, the cleaning liquid may be sprayed to the cleaning portion 110 or the vicinity of the cleaning portion 110 through the cleaning liquid delivery line 121, thereby achieving the effect of cleaning by the cleaning liquid. In addition, it is also possible that when it is necessary to clean some stubborn dirt (e.g., juice, milk stain, sauce, or other dirt adhering to the cleaning object) during cleaning by the surface cleaning apparatus 100, the cleaning liquid is sprayed to the cleaning part 110 or the vicinity of the cleaning part 110 through the cleaning liquid delivery line 121, thereby achieving the effect of cleaning by the cleaning liquid. For example, the spraying of the cleaning liquid may be initiated automatically or manually upon instruction from the user. In the case of automatic activation, the presence of dirt may be automatically detected, for example a detection sensor may be provided on or near the cleaning portion 110, and when the presence of dirt is detected, spraying of cleaning liquid is automatically activated. In the case of manual actuation, when the user realizes that the dirt needs to be cleaned, the user activates the spray of cleaning liquid, thereby removing the dirt by the action of the cleaning liquid.

In addition, a water level detection device 123 and/or a water temperature detection device 122 may be provided in the cleaning liquid storage section 120 or in the vicinity of the outside. The water level detecting means 123 may also function as in-place detecting means for detecting whether the cleaning liquid storage part 120 is in place.

The water temperature detection device 122 may also be provided to the liquid delivery pipe 121. The water level detection means may detect the volume amount of the cleaning liquid stored in the cleaning liquid storage part 120, and may alert the user to fill the cleaning liquid in case the volume amount is less than a predetermined threshold value. The water temperature detecting means may be used to detect the temperature of the cleaning liquid stored in the cleaning liquid storage section 120 so as to alert the user when the liquid temperature is less than a predetermined temperature.

The surface cleaning apparatus 100 may further include a fluid dispensing device, which may include a nozzle that may be disposed to or near the cleaning portion 110 and connected to the cleaning liquid delivery line 121, and a water pump 124 that may be disposed upstream of the nozzle and in fluid communication with the cleaning liquid delivery line 121. This allows the cleaning liquid to be sprayed to the cleaning part 110 through the nozzle by the water pump 124.

According to further embodiments of the present disclosure, the surface cleaning apparatus 100 may further include a recovery storage 130, and the recovery storage 130 may be in the form of a water tank and may be used to store recovered dirty water. After the cleaning liquid is sprayed to the cleaning part 110 and dirt is cleaned by the cleaning liquid, the used cleaning liquid may be recovered into the recovery storage part 130. Recovery of the cleaning liquid may be accomplished, for example, through recovery channel 131.

Specifically, the used cleaning liquid and dirt can be recovered in the recovery storage section 130 by a recovery system. The recovery system may include a suction power source and a suction nozzle (not shown in fig. 1 and 2). The suction power source, the suction nozzle, and the recovery passage communicate, wherein the suction nozzle may be provided on or near the cleaning portion 110, alternatively may be provided near the rear of the cleaning portion 110 (right side of the cleaning portion 110 shown in fig. 1). Thus, when liquid recovery is performed, the suction power source starts to operate, and the used cleaning liquid and dirt are sucked up by the suction nozzle and transferred to the recovery storage 130 through the recovery passage.

The recovery storage 130 may include a bottom and a top that contain liquid and dirt, with a filter device 132 disposed at the top. Thus, when the used cleaning liquid and dirt are sucked by the suction power source, the situation that the air is mixed can occur, the sucked air can be filtered through the filtering device 132 by arranging the filtering device 132 at the top, the filtered air is discharged into the atmosphere, thereby effectively realizing the gas-liquid separation, and the liquid and the dirt remain in the recovery storage part 130.

The surface cleaning apparatus 100 may further include a housing 140, wherein the housing 140 forms an accommodating space accommodating the cleaning liquid storage part 120 and the recovery storage part 130. And the case 140 may be opened to take out the detachable recovery storage 130. Thus, when the recovery storage 130 needs to be cleaned, it can be taken out and cleaned. Further, the cleaning liquid storage section 120 may be provided in a detachable form so that it can be taken out. The cleaning liquid storage section 120 may be provided in a fixed manner.

In the present disclosure, the surface cleaning apparatus is preferably an upright cleaning apparatus, and in the upright cleaning apparatus, cleaning is performed by the cleaning liquid by ejecting the cleaning liquid to the cleaning portion or the vicinity thereof, and the used cleaning liquid is sucked back into the recovery storage portion.

The surface cleaning apparatus may include a first housing for accommodating at least the cleaning liquid storage portion and a second housing for accommodating the cleaning portion, and the recovery storage portion may be provided in the first housing. Although the terms of the first housing and the second housing are described in the present disclosure, they may be integrally formed, and the terms of the first housing and the second housing are used herein only for distinguishing the arrangement positions.

The base station 200 will be described with reference to fig. 1 and 2. As shown, the base station 200 may include a cleaning liquid supply 210 and a base 220. The cleaning liquid supply part 210 may be in the form of a water tank and serves to store the cleaning liquid, and the stored cleaning liquid may be supplied to the cleaning liquid storage part 120 of the surface cleaning apparatus 100. For example, the base station 200 may include a base station water pump 230 and a water supply line 240. When the surface cleaning apparatus 100 is cooperatively connected with the base station 200, the water supply line 240 of the base station 200 is in fluid communication with the water supply line 150 of the surface cleaning apparatus 100, and the base station water pump 230 may be provided to the water supply line 240 so as to pump the cleaning liquid in the cleaning liquid supply 210 into the cleaning liquid storage 120 of the surface cleaning apparatus 100. When the water supply line 240 of the base station 200 is in fluid communication with the water supply line 150 of the surface cleaning apparatus 100, communication may be made through a connection tube therebetween (which may be provided to the surface cleaning apparatus 100 or to the base station 200, and is shown in fig. 2 as being provided to the surface cleaning apparatus 100) and a corresponding connection interface (which may be provided to the surface cleaning apparatus 100 or to the base station 200, and is shown in fig. 2 as being provided to the base station 200).

Further, a heating device 250 may be provided on the water supply line 240, wherein the heating device 250 may be used to heat the cleaning liquid supplied to the cleaning liquid storage section 120 on the water supply line.

When the surface cleaning apparatus 100 is cooperatively connected with the base station 200, the base station 200 may also charge the surface cleaning apparatus 100 by means of a charging device, for example, the base station 200 may be provided with a charging port 260 and the surface cleaning apparatus 100 may be provided with a charging plug 160, and the charging of the surface cleaning apparatus 100 is achieved by the cooperation of the two. In addition, the communication function between the surface cleaning apparatus 100 and the base station 200 can be realized through the charging port 260 and the charging plug 160, for example, data transmission can be performed. Further, both the charging function and the communication function may be controlled, for example, by the control circuit 270 provided by the base station 200 and the control circuit 170 provided by the surface cleaning apparatus 100. Wherein the control circuit 270 may be connected to the charging port 260 and the control circuit 170 may be connected to the charging plug 160. Although it is described above that the base station 200 is provided with the charging port 260 and the surface cleaning apparatus 100 is provided with the charging plug 160, it is also possible to provide the charging port to the surface cleaning apparatus 100 and the charging plug to the base station 200 accordingly.

In addition, a rechargeable battery 180 may be provided in the surface cleaning apparatus 100, and the rechargeable battery 180 may be charged by a charging device. Although described in the present disclosure as an example of a rechargeable surface cleaning apparatus, those skilled in the art will appreciate that it may also be provided in a wired manner.

In the present disclosure, it is preferable that the cleaning be performed with hot water, for example, with stubborn dirt. In the prior art, cleaning agents are commonly used to clean tough soils, as well as steam to treat tough soils. However, in the case of the detergent, the ratio of the detergent needs to be controlled, and the cleaning process of the detergent must be specially performed, which results in an increase in time and cost. In the case of steam, it is necessary for the rechargeable surface cleaning apparatus to be powered by a rechargeable battery carried by the surface cleaning apparatus when generating steam, which greatly reduces the time of use of the surface cleaning apparatus after each charge. In addition, in other ways of cleaning by heating, rechargeable batteries of the surface cleaning apparatus itself are required to supply energy, and these ways increase the energy consumption of the surface cleaning apparatus itself.

Accordingly, in the present disclosure, in order to reduce the energy loss of the surface cleaning apparatus itself, considering the problem of the cruising and water-supplying of the surface cleaning apparatus, the energy loss may be transferred to the base station. Therefore, in the present disclosure, the base station is provided with the above-described cleaning liquid supply part 210, and can be heated by the heating device 250, and the heated water is supplied to the cleaning liquid storage part 120 of the surface cleaning apparatus, and the temperature of the water stored in the cleaning liquid storage part 120 is a temperature suitable for cleaning stubborn dirt, and the water temperature stored in the cleaning liquid storage part 120 can be maintained.

After the surface cleaning apparatus 100 is returned to the base station 200, the water supply line 240 and the water supply line 150 are in fluid communication through the connection interface for water addition, so that the water in the cleaning liquid supply part 210 can be supplied to the cleaning liquid storage part 120, and the supplied water can be heated by the heating device 250, thereby supplying water of a predetermined temperature to the cleaning liquid storage part 120. Wherein each of the parts of the base station 200 is connected to an external power source through a plug as shown in the drawing to supply power.

When the surface cleaning apparatus 100 is connected to the base station 200, automatic water addition of the surface cleaning apparatus 100 can be achieved. A schematic of automatic water addition is shown in fig. 3. The automatic water adding mode can be suitable for a vertical floor washing machine and a floor mopping robot. By the automatic water feeding method of the present disclosure, the cleaning liquid supply part 210 of the base station 200 is connected to a tap water pipe or the like, and automatic water replenishment, heating, and heat preservation can be achieved by the method of the present disclosure.

The automatic water adding process of the present disclosure will be described with reference to fig. 3.

The cleaning liquid supply part 210 receives water from an external water source such as a tap water pipe and stores the water. The cleaning liquid supply part 210 communicates with the water supply line 240 through the interface 213, and pumps water by the action of the base station water pump 230. In which a vent hole 211 may be opened at the top of the cleaning liquid supply part 210 (for example, in the form of a water tank) so as to exhaust air therein, and a water amount sensor 212 may be further provided for measuring the amount of water in the cleaning liquid supply part 210. For example, when the amount of water is too small, the user may be notified of the addition of water or the addition of water from an external water source may be automatically performed, and the addition of water may be stopped when the amount of water reaches a predetermined value during the addition of water.

The water pumped by the base station water pump 230 passes through the water supply line 240 and is heated to a predetermined temperature by the heating device 250. In addition, a water temperature sensor 251 may be provided downstream of the heating device 250, the temperature of the water heated by the heating device 250 may be detected by the water temperature sensor 251, and the heating device 250 may be feedback-controlled according to the detection value of the water temperature sensor 251 so as to adjust the heating amount of the heating device 250, thereby achieving the purpose of adjusting the water temperature.

The water supply line 240 is connected to the water supply line 150 through a connection port 280. The water supply line 150 may communicate with the connection port 280 through the water supply joint 151, and water in the water supply line 240 may flow into the water supply line 150.

The water in the water supply line 150 may be transferred to the cleaning liquid storage section 120 through the distribution device 152 (three-way joint). Wherein a water temperature detecting means 122 may be provided in or near the cleaning liquid storage section 120 in order to detect the temperature of the water in the cleaning liquid storage section 120. The top of the cleaning liquid storage section 120 may also be provided with a waterproof and breathable membrane 125

When the cleaning water is supplied to the cleaning portion 110 or the vicinity thereof, the water may be supplied from the cleaning liquid storage portion 120 to the nozzle 190 by the pumping action of the water pump 124. The number of the nozzles 190 may be plural and may be set according to the form of the cleaning portion. For example, in fig. 3, a plurality of side-by-side nozzles are shown, which can be used for a washing brush.

The automatic water adding process will be described in detail with reference to fig. 4 to 7.

After the surface cleaning apparatus 100 is docked to the base station 200, the water addition connector 151 is inserted into the connection interface 280, and the charging plug 160 is inserted into the charging port 260. In order to accurately determine whether the water adding joint 151 is correctly inserted into the connection interface 280, in the present disclosure, the determination may be made by a state between the charging plug 160 and the charging port 260. For example, in the present disclosure, the water feed connection 151 is arranged in a fixed manner relative to the charging plug 160, and the connection interface 280 is arranged in a fixed manner relative to the charging port 260. The connection state of the water charging connector 151 and the charging plug 160 can be determined by the connection state of the connection interface 280 and the charging port 260 by the relative fixed distance therebetween. If it is judged that the plugging has been correct, a water adding switch (which may be provided at the position of the connection interface 280) is turned on or the base station water pump 230 is turned on, so that a water adding operation will be realized. If the connection is not correctly judged, the re-plugging is prompted until the connection is correctly plugged.

The water temperature detecting means 122 will detect the water temperature in the cleaning liquid storage section 120 and the in-place detecting means detects whether the cleaning liquid storage section 120 is in place. If in place and the water temperature detected by the water temperature detecting means 122 is greater than or equal to a first temperature threshold (e.g., 40 ℃), the base station water pump 230 is activated and the heating means 250 heats the flowing water to a predetermined water temperature, so that water can be supplied to the cleaning liquid storage section 120.

Further, in an alternative embodiment, when the water temperature is less than the first temperature threshold value, the water in the cleaning liquid storage part 120 may be pumped back into the cleaning liquid supply part 210 by the base station water pump 230, and then water may be added and simultaneously heated by the heating device 250.

Although in the above description, the water temperature in the cleaning liquid storage section 120 is detected by the water temperature detecting device 122, the water adding operation is performed only when it is greater than or equal to the first temperature threshold value. It is also possible in the present disclosure that, in the case where the temperature is less than the first temperature threshold value, the water is not drawn back to the cleaning liquid supply part 210, but the water flowing therethrough is heated to a higher temperature by adjusting the heating energy of the heating device 250, and the temperature of the water finally in the cleaning liquid storage part 120 is made greater than or equal to the first temperature threshold value.

Fig. 5 shows a schematic of a base station adding water to a surface cleaning apparatus. Wherein the arrows shown in fig. 5 indicate the water flow direction. The base station water pump 230 may pump out the water in the cleaning liquid supply part 210 and supply the water to the heating device 250 through the water supply line 240, which heats the water to a predetermined temperature, and supply the water to the water supply line 150 through the connection interface 280, and then may inject the water into the cleaning liquid storage part 120 through the dispensing device 152.

Furthermore, in order to avoid spraying hot water through the nozzle 190 during the water addition, the cleaning liquid delivery line 121 may be shut off in the inactive state of the surface cleaning apparatus 100. The shut-off may be a peristaltic pump provided on the cleaning liquid delivery line 121. A shut-off valve may also be provided on the cleaning liquid delivery line 121, which shut-off valve may be triggered to shut off the cleaning liquid delivery line 121 after the surface cleaning apparatus 100 has been docked to the base station 200.

Fig. 6 illustrates a schematic diagram of stopping water supply when the cleaning liquid storage part 120 is filled with water according to one embodiment of the present disclosure.

After the water level detection device 123 detects that the amount of water in the cleaning liquid storage part 120 reaches a predetermined value (for example, has been topped up), the control circuit 170 transmits a signal to stop water addition to the control circuit 270 according to the detection signal of the water level detection device 123, and after the control circuit 270 receives the signal, the operation of the base station water pump 230 and the heating device 250 is controlled, and the completion of water addition may be prompted. For example, the prompting means may send a signal to the control circuit 170 through the control circuit 27, and the control circuit 170 controls the broadcasting device of the surface cleaning apparatus 100 to broadcast or the warning through the warning device, etc.

As an alternative embodiment, after the surface cleaning apparatus 100 is docked at the base station 200, water is pumped from the cleaning liquid storage 120 back to the cleaning liquid supply 210 entirely by the base station water pump 230. After the suction is completed, the water is added by the base station water pump 230, and at this time, whether the cleaning liquid storage section 120 is filled up can be judged based on the storage capacity of the cleaning liquid storage section 120, the flow rate of water in the water supply line 240, and the water addition time, for example, in the case where the storage capacity of the cleaning liquid storage section 120 and the flow rate of water in the water supply line 240 are known, the filling operation of the cleaning liquid storage section 120 is completed by controlling the water addition time. After the top up, the base station water pump 230 stops working.

In addition, in a further embodiment of the present disclosure, as shown in fig. 7, water of the cleaning liquid storage part 120 may also be recovered. For example, after the water addition is completed, the user does not use the surface cleaning apparatus 100 for a predetermined time, and when the water temperature detecting device 122 detects that the water temperature in the cleaning liquid storage section 120 is too low, the water in the cleaning liquid storage section 120 may be pumped back into the cleaning liquid supply section 210 by the base station water pump 230. Further, before the base station water pump 230 performs the back pumping operation, the water pump 124 may first pump the water in the cleaning liquid delivery pipe 121 back into the cleaning liquid storage section 120, and then perform the recovery operation of the base station water pump 230. When the user needs to use the surface cleaning apparatus 100, water is supplied from the cleaning liquid supply part 210 to the cleaning liquid storage part 120 through the base station water pump 230 and heated by the heating device 250. So that the user can use hot water of a predetermined temperature while cleaning. Of course, no pumpback operation may be selected.

In addition, the reclamation operations with respect to fig. 4 to 7 may also be implemented according to an input instruction of the user.

Corresponding to fig. 4-6, the present disclosure also provides a water addition control method 800. Fig. 8 shows a flow chart of the method. The descriptions with respect to fig. 4 to 6 are also applicable to the control method, and a detailed description will be omitted for some portions.

In step 802, after the surface cleaning apparatus is docked to the base station, the water charging line is connected and the charging communication line is also connected, in order to accurately determine whether the water charging line is properly connected, in this disclosure, the determination may be made by the connection state of the charging communication line. If the plugging is judged to be correct, water adding operation is carried out. If the connection is not correctly judged, the re-plugging is prompted until the connection is correctly plugged.

Further, the water temperature in the cleaning liquid storage section 120 is detected, and whether the cleaning liquid storage section 120 is in place is detected. If in place and the water temperature detected by the cleaning liquid storage portion 120 is greater than or equal to a first temperature threshold (e.g., 40 ℃), a water adding operation is started and the added water is heated to a predetermined water temperature, so that water can be supplied to the cleaning liquid storage portion 120.

Further, in an alternative embodiment, when the water temperature is less than the first temperature threshold, the water in the cleaning liquid storage part 120 may be pumped back into the cleaning liquid supply part 210, and then water may be added and simultaneously heated.

In step 804, the base station adds water to the surface cleaning apparatus, and the base station may pump out the water in the cleaning liquid supply part 210 and then supply water and simultaneously heat the water, and supply the water to the cleaning liquid storage part 120 after heating to a predetermined temperature.

In step 806, the addition of water is stopped. After detecting that the amount of water in the cleaning liquid storage section 120 reaches a predetermined value (e.g., has been topped up), the control base station stops adding water, and may prompt that the water addition is completed. As an alternative embodiment, after the surface cleaning apparatus 100 is docked at the base station 200, water is drawn from the cleaning liquid storage 120 all the way back to the cleaning liquid supply 210. After the suction is completed, the water addition is performed, and at this time, whether the cleaning liquid storage section 120 is filled up or not may be judged based on the storage capacity of the cleaning liquid storage section 120, the flow rate of water, and the water addition time, and for example, the filling operation of the cleaning liquid storage section 120 is completed by controlling the water addition time in the case where the storage capacity of the cleaning liquid storage section 120 and the flow rate of water are known. After the base station is topped up, the base station stops adding water.

Corresponding to fig. 4-7, the present disclosure also provides a water addition control method 900. Fig. 9 shows a flow chart of the method. The description with respect to fig. 4 to 7 is also applicable to the control method, and a detailed description will be omitted for some portions.

In step 902, after the surface cleaning apparatus is docked to the base station, the water charging line is connected and the charging communication line is also connected, in order to accurately determine whether the water charging line is properly connected, in this disclosure, the determination may be made by the connection state of the charging communication line. If the plugging is judged to be correct, water adding operation is carried out. If the connection is not correctly judged, the re-plugging is prompted until the connection is correctly plugged.

In step 904, water for cleaning the liquid storage section 120 is recovered. For example, after the water addition is completed, the user does not use the surface cleaning apparatus 100 for a predetermined time, and when the water temperature in the cleaning liquid storage section 120 is too low, the water in the cleaning liquid storage section 120 may be drawn back into the cleaning liquid supply section 210. Further, before the back-pumping operation, the water in the cleaning liquid conveying line 121 may be first pumped back into the cleaning liquid storage section 120, and then the recovery operation may be performed. When the user needs to use the surface cleaning apparatus 100, water is supplied from the cleaning liquid supply part 210 to the cleaning liquid storage part 120 and heating is performed. So that the user can use hot water of a predetermined temperature while cleaning. Of course, no pumpback operation may be selected.

In step 906, the base station adds water to the surface cleaning apparatus, and the base station may pump out the water in the cleaning liquid supply part 210 and then supply water and simultaneously heat the water, and supply the water to the cleaning liquid storage part 120 after heating to a predetermined temperature.

In step 908, the addition of water is stopped. After detecting that the amount of water in the cleaning liquid storage section 120 reaches a predetermined value (e.g., has been topped up), the control base station stops adding water, and may prompt that the water addition is completed. As an alternative embodiment, after the surface cleaning apparatus 100 is docked at the base station 200, water is drawn from the cleaning liquid storage 120 all the way back to the cleaning liquid supply 210. After the suction is completed, the water addition is performed, and at this time, whether the cleaning liquid storage section 120 is filled up or not may be judged based on the storage capacity of the cleaning liquid storage section 120, the flow rate of water, and the water addition time, and for example, the filling operation of the cleaning liquid storage section 120 is completed by controlling the water addition time in the case where the storage capacity of the cleaning liquid storage section 120 and the flow rate of water are known. After the base station is topped up, the base station stops adding water.

In the above embodiments of the present disclosure, the cleaning liquid storage section 120 is provided in the surface cleaning apparatus 100, and when the surface cleaning apparatus 100 is docked at the base station 200, mode selection (charging mode, water adding mode, charging water adding mode) can be automatically performed. After the sensor of the base station 200 senses that the surface cleaning apparatus 100 is stopped, it is judged by the water level detecting means 123 whether the water level of the cleaning liquid storage section 120 is greater than the first water level threshold, and if so, it is indicated that water is not required to be added at this time, and a charging mode is selected. If the water level of the cleaning liquid storage section 120 is less than or equal to the first water level threshold value and greater than the second water level threshold value, the mode selection is not determined at this time, and the user may be prompted to select the mode. If the water level is less than or equal to the second water level threshold, a water adding mode is selected, and a charging mode can be started. Further, whether or not to perform the charging mode may also be determined by judging the amount of electricity of the battery of the surface cleaning apparatus 100, the principle of which is the same as that described above.

A flow chart of a mode selection method 1000 is presented in fig. 10. In step 1002, it is determined that the surface cleaning apparatus 100 is reliably connected to the base station 200, and if the connection is reliable, mode selection (charging mode, water-adding mode, charging water-adding mode) can be automatically performed. In step 1004, it is determined whether the water level of the cleaning liquid storage section 120 is greater than a first water level threshold, and if so, step 1006 is entered, indicating that no water addition is required at this time, and the charging mode is selected. Otherwise, step 1008 is entered, if the water level is less than or equal to the first water level threshold and greater than the second water level threshold, step 1010 is entered, and the user may be prompted to select a mode without determining a mode selection. Otherwise, step 10012 is entered, and if the water level is less than or equal to the second water level threshold, the water adding mode is selected, and the charging mode may be also turned on.

According to the embodiment of the disclosure, the effect of cleaning by hot water is achieved, stubborn dirt can be cleaned more effectively, energy consumption is reduced, an automatic water adding mode can be adopted, the use of a user is facilitated, the disassembly times of the water tank are reduced, and the operation of the user is simplified.

Further, in the embodiments of the present disclosure, the effect of removing stubborn dirt is achieved by supplying hot water of more than a predetermined temperature, and thus in order to secure the temperature of the supplied hot water, an insulation layer may be provided in the present disclosure.

A first heat-retaining layer 1201 may be provided at the outer side of the cleaning liquid storage part 120, and the first heat-retaining layer 1201 may wrap the outer side of the cleaning liquid storage part 120. A second insulation layer 1211 may be provided at the outer side of the cleaning liquid delivery line 121, and the second insulation layer 1211 may wrap the outer surface of the cleaning liquid delivery line 121. A third heat insulating layer 1501 may be disposed on the water supply line 150, and the third heat insulating layer 1501 may wrap the outer surface of the water supply line 150.

By providing the heat insulating layer on the outer surfaces of the cleaning liquid storage part 120, the cleaning liquid delivery pipe 121 and the water supply pipe 150, the water outlet efficiency of the hot water can be remarkably improved, thereby achieving a better cleaning effect and an energy saving effect. Although the heat insulating layer is provided at the outside in the above description, the heat insulating layer may be provided to the cleaning liquid storage section 120, the cleaning liquid delivery line 121, and/or the water supply line 150 by way of an interlayer, which is not limited in the present disclosure.

The base station 200 of the embodiment of the present disclosure will be described in detail below. The cleaning liquid supply part 210 may be connected to an external tap water pipe so as to supply water to the cleaning liquid supply part 210 through the external tap water pipe. And the base station water pump 230 may pump the cleaning liquid supply part 210 to the heating device 250, and the heating device 250 heats the water in the water supply line 240 and then supplies the water to the surface cleaning apparatus 100 through the connection interface 280. So that water in the cleaning liquid supply part 210 is supplied to the cleaning liquid storage part 120 through the pipe by the connection of the connection interface 280 with the water-adding joint 151.

In the present disclosure, the heating device 250 may be an instant heating assembly, and by instant heating of water flowing therethrough, it is possible to prevent the problem of energy waste due to a reduction in water temperature due to long-term standing of water in the case of heating in the cleaning liquid supply part 210.

The heating device 250 can be provided with more than two heating modes, and the heating power of each mode is different, so that the water temperature can be increased to different temperatures through the heating device 250, thereby meeting the requirements of different situations. For example, in the case of ordinary maintenance cleaning, the water temperature may be heated to a first temperature by the heating device 250, and in the case of deep cleaning, the water temperature may be heated to a second temperature, wherein the second temperature is greater than the first temperature. Of course, those skilled in the art will appreciate that a variety of other temperatures may be provided to meet different needs.

Further, when there is no water in the cleaning liquid supply portion 210, the heating device 250 is not activated. At this time, it is necessary to consider the activation of the heating device 250 after the cleaning liquid supply portion 210 is filled with water.

Further, as mentioned above, the water temperature is raised to different temperatures by the heating device 250, and according to an embodiment of the present disclosure, control may also be performed by a detection value of the water temperature sensor 251, for example, when the water temperature sensor 251 detects that the water supplied from the heating device 250 is higher than a predetermined temperature, the heating power of the heating device 250 is lowered, whereas if it is lower than the predetermined temperature, the heating power of the heating device 250 is raised.

The predetermined water temperature may also be obtained by the cooperation of the water temperature sensor 251 and the base station water pump 230. For example, when the water temperature sensor 251 detects that the water supplied from the heating device 250 is higher than a predetermined temperature, the flow rate of the base station water pump 230 is increased, and if it is lower than the predetermined temperature, the flow rate of the base station water pump 230 is decreased. In addition, according to the same principle, the water temperature can be adjusted by the water temperature sensor 251 in cooperation with the heating device 250 and the base station water pump 230 at the same time. For example, when the water temperature sensor 251 detects that the water supplied from the heating device 250 is higher than a predetermined temperature, the flow rate of the base station water pump 230 is increased and/or the heating power of the heating device 250 is decreased, whereas if the water temperature is lower than the predetermined temperature, the flow rate of the base station water pump 230 is decreased and/or the heating power of the heating device 250 is increased.

The base station 200 may include a base station housing 290, and the base station housing 290 may include a first housing 291, a second housing 292, and a third housing 293. Wherein the first housing 291 may constitute the base 220 for accommodating the cleaning portion 110 of the surface cleaning apparatus 100, the first housing 291 may have a length greater than a height, and the base station 200 may be supported on the bottom surface by the first housing 291. The second housing 292 may be in the form of a side housing and may extend vertically with respect to the first housing 291, the first housing 291 being disposed on a first side of the second housing 292. The third housing 293 may be disposed on a second side of the second housing 292, wherein the first side is opposite the second side. The third housing 293 is for supporting the cleaning liquid supply portion 210. The third housing 293 may not be provided, but the cleaning liquid supply portion 210 may be fixed to the second side of the second housing 292. Although the cleaning liquid supply portion 210/third housing 293 is shown spaced apart from the floor surface by a certain distance in the drawing, it may be provided on the floor surface, that is, the bottom surface of the cleaning liquid supply portion 210/third housing 293 is flush with the bottom surface of the first housing 291.

The first housing 291 and the second housing 292 may be in spatial communication and serve to house components of the base station 200. For example, the water supply line 240, the base station water pump 230, the heating device 250, the control circuit 270, the water temperature sensor 251, and the like may be accommodated in the second housing 292. An external power cord may be connected through the base station housing 290 to an external power source to power the base station. Further, the first housing 291 may be used to support the surface cleaning apparatus 100, so that a groove 294 matching the surface cleaning apparatus 100 may be provided at an upper side of the first housing 291, for example, when an upright surface cleaning apparatus is used, the surface cleaning apparatus may be stably supported on the base 220. Further, the second housing 292 is detachable with respect to the first housing 291, which can facilitate maintenance.

Further, the base station 200 may be provided with a drying and sterilizing apparatus to dry and sterilize the cleaning part 110 such as a cleaning head.

As shown in fig. 12, the drying and sterilizing apparatus may include an air supply unit 221, a heating unit 222, and an air duct 223. Wherein the air duct 223 may be integrally formed with at least the first housing 291. The air duct 223 includes an air inlet and an air outlet, wherein the air inlet is disposed near the air supply assembly 221 such that the air supplied from the air supply assembly 221 is received through the air inlet. The heating component 222 is disposed at or near the air inlet, and the air supplied from the air supply component 221 is heated by the heating component 222, and then flows into the air duct 223 and is sent out from the air outlet. The air outlet may be provided at or near the groove 294 accommodating the cleaning part 110 so that the heated wind dries the cleaning part 110. A sterilizing unit 224 may be provided, and the cleaning portion 110 may be sterilized by the sterilizing unit 224. For example, the sterilizing unit 224 may be an ozone generator, and the sterilizing unit 224 may be provided in the air duct 223, generate ozone through the ozone generator, and send out to the cleaning part 110 through an air outlet of the air duct 223 to sterilize the same.

In fig. 12, the number of air channels 223 is shown as one, but in the present application, the number of air channels is preferably two. Wherein the first air duct may provide a drying function and the second air duct may provide a sterilizing function. And both air ducts provide a source of air for the air supply assembly 221. The heating assembly 222 may be disposed at or near the air inlet of the first air duct, the sterilizing assembly 224 is disposed in the second air duct, and the air outlets of both air ducts may be disposed at or near the recess 294. In addition, the heating assembly 222 may also be disposed at or near the air inlets of the first and second air ducts simultaneously to provide hot air to both air ducts.

When the surface cleaning apparatus 100 is docked to the base station 200, a prompt message may be issued by the surface cleaning apparatus 100 or the base station 200 to prompt the user whether to perform the self-cleaning disinfecting mode. The self-cleaning sterilization mode may also be automatically performed.

If the self-cleaning sterilization mode is performed, the cleaning portion 110 of the surface cleaning apparatus 100 is cleaned and sterilized.

When the surface cleaning apparatus 100 is docked to the base station 200, the grooves 294 form a space with the cleaning portion 110, such as a cleaning head, for water to flow along the cleaning portion 110 (e.g., the cleaning portion 110 is suspended in the grooves 294) so that water can flow over the outer side of the cleaning portion 110. The water flow may now be provided through the nozzle 190 of the surface cleaning apparatus 100. The cleaning part 110 rotates while the water flow is supplied, the cleaning part 110 is cleaned by the water as the cleaning part 110 rotates, and the water in the groove 294 increases as time goes by, so that the cleaning part 110 can sufficiently contact with the water in the groove 294, and thus the cleaning part 110 can be deeply cleaned.

After the washing is completed, the waste water may be pumped into the recovery storage 130 by the surface cleaning apparatus 100. Then can disinfect, at this time can export hot-blast and ozone ion through the wind channel. For example, in the case of two air ducts, the hot air may be guided out through the first air duct and the low concentration ozone ions may be guided out through the second air duct, thereby achieving the drying and sterilizing operation of the cleaning part 110.

The used gas may be sucked into the recovery storage 130 while the drying sterilization is performed, and the gas is filtered by the filtering device 132, and the filtered clean gas is discharged into the general. This also achieves sterilization and disinfection of the recovery storage 130 and its piping, and disinfection of the upper surface of the base 220 at the same time.

Accordingly, the present disclosure also provides a method 1300 of cleaning, drying, and disinfecting a surface cleaning apparatus.

In step 1302, the cleaning portion is washed by water to remove dirt and the like adhering to the surface.

In step 1304, the clean used water is drained. After the washing is completed, the waste water may be pumped into the recovery storage 130 by the surface cleaning apparatus 100

In step 1306, the cleaning portion is dried and sterilized. At this time, hot air and ozone ions can be led out through the air duct. For example, in the case of two air ducts, the hot air may be guided out through the first air duct and the low concentration ozone ions may be guided out through the second air duct, thereby achieving the drying and sterilizing operation of the cleaning part 110.

In step 1308, the gas for drying and sterilization is sucked, filtered, and discharged to the atmosphere. The used gas may be sucked into the recovery storage 130 while the drying sterilization is performed, and the gas is filtered by the filtering device 132, and the filtered clean gas is discharged into the general. This also achieves sterilization and disinfection of the recovery storage 130 and its piping, and disinfection of the upper surface of the base 220 at the same time.

In addition, in order to prevent clogging of a pipe caused by scale generated from the heating device 250, a water softening device 241 may be provided between the cleaning liquid supply part 210 and the heating device 250. As shown in fig. 12, the water softening device 241 may be provided at the water outlet of the cleaning liquid supply part 210.

As a modification, the water softening device may be provided between the water inlet of the cleaning liquid supply portion 210 and the tap water pipe.

Further, a drain pipe of the cleaning liquid supply portion 210 may be connected to a drain pipe of a washing machine, a drain pipe of a kitchen, or the like, so as to drain water of the cleaning liquid supply portion 210.

In the previous figures, the charging port 260 is located at a level with the connection interface 280, but preferably, both may be located at a stepped arrangement, for example, the connection interface 280 may be located at a lower level than the charging port 260. This may firmly support the surface cleaning apparatus 100 by the base station 200. But also the length of the water supply line 240 can be shortened, so that heat loss can be reduced.

For the water temperature sensor 251 and the water temperature detecting device 122, the water temperature sensor 251 is preferably disposed at a position close to the connection interface 280, and the water temperature detecting device 122 may be disposed at the bottom of the cleaning liquid storage part 120. This can better improve the use effect. Further, only the water temperature detecting means 122 may be provided to realize the functions of both the water temperature sensor 251 and the water temperature detecting means 122.

In the above embodiments, the heating device is provided in the base station 200.
