Technical Field

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

Background

Today's surface cleaning devices are used for wet cleaning hard floors or short-hair carpets. The device typically has one or more rolling brushes or cleaning discs made of a wool material which can scrub tough soils on the floor by adding water or a water/cleaner mixture.

As the machine moves over the dirt, the dirt that has been wiped off by the roller brush and dissolved by the water or water/detergent mixture is picked up with the cleaning head aligned in the direction of movement of the roller brush and stored in the dirty water tank of the surface cleaning apparatus.

When sewage or other solid dirt exists in the sewage tank, the sewage tank needs to be disassembled and manually cleaned, so that time and labor are wasted; furthermore, when the manual cleaning of the sewage tank is not thorough, the inside of the sewage tank may get moldy and smelly, which affects the user experience.

Fig. 1 is a schematic structural view of a surface cleaning system according to one embodiment of the present disclosure. Fig. 2 is an exploded schematic view of a surface cleaning system according to one embodiment of the present disclosure.

As shown in fig. 1 and 2, the present disclosure provides a surface cleaning system that may include a surface cleaning apparatus 100 and a base station 200.

In the case shown in fig. 1, that is, after the surface cleaning apparatus 100 and the base station 200 are combined, when the surface cleaning apparatus 100 is parked at the base station 200, the surface cleaning apparatus 100 may be charged by the base station 200, the cleaning liquid, or the water circulation with the surface cleaning apparatus may be supplied to the cleaning liquid storage unit 120 of the surface cleaning apparatus 100, or the cleaning liquid may be supplied to the recovery storage unit 130 of the surface cleaning apparatus 100, so that the recovery storage unit of the surface cleaning apparatus 100 is cleaned.

In the present disclosure, 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, 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 cordless hand-held upright surface cleaning apparatus. While applicable to other types of surface cleaning apparatuses, those skilled in the art will appreciate that corresponding modifications can be made to the types of surface cleaning apparatuses specifically described in this disclosure and will not be described in detail herein.

Furthermore, the surface cleaning apparatus 100 may be used for cleaning floors or short-hair carpets, but also for cleaning other objects, such as glass, etc.

As shown in fig. 1, the surface cleaning apparatus 100 may include a cleaning portion 110 and a cleaning liquid storage portion 120.

The cleaning part 110 may be bristles provided on an outer circumferential surface of the roll brush. And cleaning of the surface to be cleaned is achieved by the rolling movement of the bristles.

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 delivery pipe 121.

In the present disclosure, the cleaning liquid is preferably cleaning hot water having a temperature greater than or equal to a first temperature threshold. During the whole cleaning process of the surface cleaning apparatus 100, the cleaning liquid can be sprayed to the cleaning part 110 or the vicinity of the cleaning part 110 through the cleaning liquid delivery pipe 121, so that the cleaning effect by the cleaning liquid is achieved. Furthermore, when some stubborn dirt (for example, juice, milk stain, sauce, or other dirt adhered to a cleaning object) needs to be cleaned during cleaning by the surface cleaning apparatus 100, cleaning liquid is sprayed to the cleaning portion 110 or the vicinity of the cleaning portion 110 through the cleaning liquid delivery pipe 121, so that the cleaning by the cleaning liquid is achieved. 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, the spraying of the cleaning liquid is automatically activated. In the case of manual activation, when the user recognizes that the dirt needs to be cleaned, the user activates the spraying of the cleaning liquid so that the dirt is removed by the action of the cleaning liquid.

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

A water temperature detection device 122 may also be provided to the cleaning 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 the case where 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 part 120 so as to alert the user when the liquid temperature is less than a predetermined temperature.

Surface cleaning apparatus 100 may further include a fluid distribution device that may include a cleaning nozzle (not shown) that may be disposed to or near cleaning portion 110 and connected to cleaning liquid delivery line 121, and a cleaning water pump 124 that may be disposed upstream of the cleaning nozzle and in fluid communication with cleaning liquid delivery line 121. This may spray the cleaning liquid to the cleaning part 110 through the cleaning nozzle by the cleaning water pump 124.

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

Specifically, the used cleaning liquid and dirt can be recovered to the recovery storage unit 130 by the main unit suction unit 160. The host suction assembly 160 is used for generating negative pressure, wherein the negative pressure generated by the host suction assembly 160 is applied to a suction nozzle via the recovery storage part 130, wherein the suction nozzle may be arranged on or near the cleaning part 110, optionally in the rear vicinity of the cleaning part 110. Thus, when the fluid is recovered, the main suction unit 160 starts to operate, and sucks the used cleaning fluid and dirt through the suction nozzle, and conveys the cleaning fluid and dirt to the recovery storage unit 130 through the recovery channel, and at this time, the recovery storage unit 130 is connected to the suction nozzle through the recovery channel.

In the present disclosure, a part of an outer sidewall of the recovery storage part 130 and a part of an inner sidewall of the housing 140 enclose a part of the recovery passage 131.

The surface cleaning apparatus 100 further includes a cleaning part 170 to clean the recovery storage part 130 by the high-pressure cleaning liquid output from the cleaning part 170 when the cleaning liquid is supplied to the cleaning part 170, that is, the cleaning part 170 sprays the high-pressure cleaning liquid to the recovery storage part 130 to clean the recovery storage part 130; in the present disclosure, the cleaning part 170 may include a cleaning head, at least a portion of which is located inside the recovery storage part 130 to spray cleaning liquid to an inner wall surface of the recovery storage part 130 through the cleaning head to clean the recovery storage part 130.

As another implementation form, the cleaning part 170 may further include a flushing port formed on a side wall of the recovery storage part 130, and when cleaning liquid is supplied to the flushing port, the cleaning liquid is delivered to an inner wall surface of the recovery storage part 130, thereby cleaning the recovery storage part 130.

In an alternative embodiment of the present disclosure, the housing 140 forms an accommodation space that accommodates the cleaning liquid storage part 120 and the recovery storage part 130. And the case 140 may be opened to take out the detachably accommodating cleaning liquid storage part 120 and the recovery storage part 130 and replace the accommodating cleaning liquid storage part 120 and the recovery storage part 130.

Of course, the storage unit 120 for containing the cleaning liquid and the recovery storage unit 130 may be provided in a non-replaceable mode, that is, both the storage unit 120 for containing the cleaning liquid and the recovery storage unit 130 may be provided in a fixed manner.

The base station 200 is described below in conjunction with fig. 1. As shown, the base station 200 may include a cleaning liquid supply 210 and a base 220. The cleaning liquid supply 210 may be in the form of a tank and is used to store cleaning liquid and may provide the stored cleaning liquid to the cleaning liquid storage 120 of the surface cleaning apparatus 100.

For example, the base station 200 can include a base station water supply line 240, and when the surface cleaning apparatus 100 is mated with the base station 200, the base station water supply line 240 of the base station 200 is in fluid communication with the main water supply line 150 of the surface cleaning apparatus to provide cleaning liquid in the cleaning liquid supply 210 of the base station 200 to the cleaning liquid storage 110 of the surface cleaning apparatus 100.

As one implementation form, the main water supply line 150 may be independently connected to the cleaning liquid storage part 110, thereby implementing the supply of the cleaning liquid into the cleaning liquid storage part 110; as another implementation form, the main water supply line 150 may also be connected to the cleaning liquid delivery line 121 to supply the cleaning liquid into the cleaning liquid storage part 120 through the cleaning liquid delivery line 121.

Accordingly, the base station 200 can also enable the recovery of cleaning liquid through the main water supply line 150, i.e., the cleaning liquid in the cleaning liquid storage 120 of the surface cleaning apparatus 100 to be recovered to the base station.

In the present disclosure, a heating device 250 is provided on the base station water supply line 240 to heat the cleaning liquid flowing in the base station water supply line 240 by the heating device 250, so that the temperature of the cleaning liquid added to the cleaning liquid storage part of the surface cleaning apparatus 100 is controlled to a preset value.

When surface cleaning apparatus 100 is mated with base station 200, base station 200 may also charge surface cleaning apparatus 100 via a charging device, e.g., base station 200 may be provided with a charging port and surface cleaning apparatus 100 may be provided with a charging plug, with mating of both to effect charging of surface cleaning apparatus 100.

In addition, the communication between the surface cleaning apparatus 100 and the base station 200 may be performed via a charging port and a charging plug, for example, to allow data transmission. Furthermore, both the charging function and the communication function may be controlled, such as by a control circuit provided with the base station 200 and a control circuit provided with the surface cleaning apparatus 100.

Additionally, a rechargeable battery may be provided in the surface cleaning apparatus 100, which is charged by the charging device. Although the rechargeable surface cleaning apparatus is described in the present disclosure by way of example, it will be understood by those skilled in the art that it may also be provided in a wired manner.

In the present disclosure, it is preferable that the cleaning is performed by hot water, for example, cleaning stubborn dirt. In the prior art, detergents are generally used to clean stubborn dirt, and there are also ways to treat stubborn dirt with steam. However, when the cleaning agent is used, the ratio of the cleaning agent needs to be controlled, and the cleaning process of the cleaning agent must be specially performed, which results in an increase in time and cost. With steam, rechargeable surface cleaning devices require a rechargeable battery carried by the surface cleaning device to provide energy during the generation of steam, which greatly reduces the amount of time the surface cleaning device is used after each charge. In addition, in other heating methods, a rechargeable battery of the surface cleaning device is required to provide energy, which increases the energy consumption of the surface cleaning device.

Thus, in the present disclosure, to reduce the energy loss of the surface cleaning apparatus itself, the energy loss may be transferred to a base station, taking into account the problems of cruising and water-holding of the surface cleaning apparatus. Therefore, in the present disclosure, the base station is provided with the above-described cleaning liquid supply part 210, and can supply heated water to the cleaning liquid storage part 120 of the surface cleaning apparatus by heating with the heating device 250, and the temperature of the water stored in the cleaning liquid storage part 120 is a temperature suitable for cleaning stubborn dirt, and the temperature of the water 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 base station water supply line 240 and the main water supply line 150 are fluidly connected, so that the cleaning liquid in the cleaning liquid supply part 210 can be supplied to the cleaning liquid storage part 120, and the supplied cleaning liquid can be heated by the heating device 250, thereby supplying the cleaning liquid at a predetermined temperature to the cleaning liquid storage part 120.

On the other hand, after the surface cleaning apparatus 100 returns to the base station 200, the base station is also used to clean the recycling storage 130 of the surface cleaning apparatus 100.

For example, the host recovery pipe 132 of the recovery storage unit 130 is connected to the base station recovery pipe 261 of the base station 200, so that the dirt in the recovery storage unit 130 is recovered to the base station 200 through the host recovery pipe 132 and the base station recovery pipe 261.

In the present disclosure, the host recovery pipe 132 is connected to the recovery storage unit 130.

In this case, the base station 200 includes a contaminated liquid storage unit 260, the base station recovery pipeline 261 is connected to the contaminated liquid storage unit 260, and for example, one end of the base station recovery pipeline 261 is connected to an upper half portion of a side wall of the contaminated liquid storage unit 260 or a top wall of the contaminated liquid storage unit 260.

In the present disclosure, a filtering member 262 is disposed inside the dirty liquid storage 260, wherein the filtering member 262 is disposed below a liquid inlet of the dirty liquid storage 260 through the base station recycling line 261, so that the dirty liquid recycled through the base station recycling line 261 is filtered by the filtering member 262.

In one implementation, the base station 200 includes a dirty water pump (not shown) disposed in the base station recycling pipeline 261 to recycle the dirty water in the recycling storage unit to the dirty liquid storage unit 260 when the dirty water pump is operated.

As another implementation form, the base station 200 may further include a base station suction assembly 270, and the base station suction assembly 270 is connected to the dirty liquid storage 260 and is used for generating negative pressure. When the base station suction module 270 generates negative pressure, the contaminants in the recovery storage unit 130 are recovered to the contaminated liquid storage unit 260 by the negative pressure suction effect.

Preferably, the connection of the base station suction assembly 270 to the dirty liquid storage 260 is at the top wall of the dirty liquid storage 260.

In the present disclosure, the surface cleaning apparatus 100 includes a first cleaning conduit 171, the base station 200 includes a second cleaning conduit 280, and when the surface cleaning apparatus 100 is docked at the base station 200 and is in mating connection with the base station 200, the first cleaning conduit 171 of the surface cleaning apparatus 100 is in fluid communication with the second cleaning conduit 280 of the base station 200 to provide cleaning liquid in the cleaning liquid supply 210 of the base station to the recovery reservoir 130 of the surface cleaning apparatus 100; wherein the first cleaning pipe 171 is connected to the cleaning part 170.
