Technical Field

The present disclosure relates to a cleaning base, a side cleaning assembly, and a cleaning head.

Background

Existing floor cleaners perform cleaning of floors with a high flow of cleaning liquid in a manner that is capable of completely wetting the floor to be cleaned. The cleaning head transfers dust from the floor to the cleaning liquid by wetting the hard floor surface, after which the cleaning liquid is removed from the hard floor surface and held as contaminated cleaning liquid in the recovery storage.

Wet surface cleaners generally have: a cleaning liquid storage section for containing a cleaning liquid; a recovery storage unit for recovering contaminants recovered from the floor to be cleaned; a motor-driven vacuum source for forming a vacuum-pumping flow path from the cleaned floor to the recovery storage part; a rechargeable battery to provide energy to each component; a base station for charging and post-cleaning maintenance of the wet surface cleaner.

However, in use of the wet surface cleaner, since the cleaning portion is located in front of the entire wet surface cleaner, in some use situations, such as cleaning corners, there is no way to clean a partial area regardless of the direction from which the wet surface cleaning apparatus is approaching the wall.

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.

As shown in fig. 1, the wet surface cleaning apparatus of the present disclosure is used for cleaning a floor surface to be cleaned, and preferably, is capable of wet cleaning the floor surface to be cleaned and recovering liquid after cleaning the floor surface to be cleaned to the wet surface cleaning apparatus.

As shown in fig. 1, the wet surface cleaning apparatus may include a handle portion 100, a frame portion 200, a cleaning liquid storage portion 300, a recovery storage portion 400, a connection portion 500, a cleaning head 600, and the like in terms of structure.

In use, the wet surface cleaning apparatus of the present disclosure, the cleaning head 600 is configured to be movable over a floor surface to be cleaned to wet clean the floor surface to be cleaned by the cleaning head 600.

The handle portion 100 is used for operating the wet surface cleaning apparatus, more specifically, on the one hand, an operator can realize control of the posture of the wet surface cleaning apparatus by operating the handle portion 100, for example, by controlling the handle portion 100, the wet surface cleaning apparatus can be in an inclined state (i.e., an angle of approximately 60 ° with the surface to be cleaned) or in a substantially lying state (i.e., substantially parallel with the surface to be cleaned); accordingly, when the frame part 200 of the wet surface cleaning apparatus is in an inclined state (i.e., an angle of about 60 ° with the surface to be cleaned) or a substantially lying state (i.e., substantially parallel with the surface to be cleaned), the wet surface cleaning apparatus is in a cleaning mode and is capable of cleaning the surface to be cleaned. Accordingly, when the handle part 100 is operated such that the frame part 200 of the wet surface cleaning apparatus is in a vertical state, the wet surface cleaning apparatus is in a stopped state at this time, or when the wet surface cleaning apparatus is in a base station, the frame part 200 of the wet surface cleaning apparatus is also in a substantially vertical state.

On the other hand, physical buttons may be provided on the handle part 100, so that the wet surface cleaning apparatus is controlled by the physical buttons, for example, the start and stop of the wet surface cleaning apparatus is controlled, the liquid supply speed and the suction power of the wet surface cleaning apparatus are controlled, and the user of the wet surface cleaning apparatus has better use experience.

The handle part 100 can be provided at an upper end of the frame part 200, so that the wet surface cleaning apparatus can be operated by operating the handle part 100. In the present disclosure, the frame part 200 is formed as a main force structure of the wet surface cleaning apparatus, and both the cleaning liquid storage part 300 and the recovery storage part 400 of the wet surface cleaning apparatus can be directly or indirectly fixed to the frame part 200.

The cleaning liquid storage part 300 is formed in the shape of a tank to store the cleaning liquid in the cleaning liquid storage part 300. In one embodiment, the cleaning liquid may be clean water. Of course, those skilled in the art will recognize that the cleaning liquid storage portion 300 may store a mixture of clean water and cleaning agent.

The frame part 200 is formed with a receiving space thereon, and the cleaning liquid storage part 300 can be disposed in the receiving space such that a portion of the outer surface of the cleaning liquid storage part 300 is formed as a portion of the outer surface of the wet surface cleaning apparatus.

In the present disclosure, the cleaning liquid storage part 300 is detachable from the frame part 200 and is manually filled with cleaning liquid by a user; of course, the cleaning liquid storage portion 300 of the present disclosure may also be filled with the cleaning liquid of the cleaning liquid storage portion 300 through the cleaning liquid interface provided on the frame portion 200.

Still further, when the cleaning liquid interface is provided on the frame part 200, the cleaning liquid storage part 300 may be provided inside the frame part 200, in which case the cleaning liquid storage part 300 is not formed as at least part of the outer surface of the wet surface cleaning apparatus.

In the present disclosure, in order to achieve cleaning of a surface to be cleaned, the cleaning liquid storage part 300 is connected to the cleaning head 600 at least through a cleaning liquid line, thereby supplying a cleaning liquid to the cleaning head 600 and thus achieving wet cleaning of the surface to be cleaned.

As shown in fig. 1, the frame part 200 is formed with a receiving space, and the recovery storage part 400 is detachably provided to the frame part 200 and is positioned in the receiving space, so that when the liquid stored in the recovery storage part 400 is more, a user can remove the recovery storage part 400, pour out the sewage inside and clean up the solid garbage, and at this time, a part of the outer surface of the recovery storage part 400 is formed as a part of the outer surface of the wet surface cleaning apparatus.

In order to recover the liquid after cleaning the surface to be cleaned, the recovery storage 400 can be connected to the cleaning head 600 through a recovery pipe 401, and accordingly, a mixture of sewage and gas (dirt) can be recovered to the recovery storage 400 through the recovery pipe 401.

Accordingly, the wet surface cleaning apparatus further comprises a suction device (not shown in the drawings), wherein the suction device is capable of generating a negative pressure and providing the negative pressure to the recovery storage 400, thereby realizing a forced flow of gas and sewage within the recovery line 401. In the present disclosure, the gas discharged from the suction device can flow to the outside of the wet surface cleaning apparatus through a slit on a part of the outer surface of the wet surface cleaning apparatus.

The frame part 200 is connected to the cleaning head 600 through the connection part 500 such that the frame part 200 is pivotably connected to the cleaning head 600, and in the present disclosure, the frame part 200 has at least two degrees of rotational freedom with respect to the cleaning head 600, thereby enabling a user to more conveniently operate the wet surface cleaning apparatus.

The structure of the cleaning head 600 is described in detail below with reference to the accompanying drawings.

Fig. 2 is a schematic structural view of a cleaning head of a wet surface cleaning apparatus according to one embodiment of the present disclosure. Fig. 3 is a schematic view of another angle of a cleaning head of a wet surface cleaning apparatus according to one embodiment of the present disclosure. Fig. 4 to 6 are schematic structural views of a partial structure of a cleaning head of a wet surface cleaning apparatus according to one embodiment of the present disclosure.

In the present disclosure, as shown in fig. 2 to 6, the cleaning head 600 may include a housing 610, a suction nozzle 620, a first stirring member 630, a cover 640, a side cleaning assembly 660, and the like.

The housing 610 is configured to be connected to the frame portion 200 by a connection portion 500, and the housing 610 is adapted to be moved over a floor surface to be cleaned. For example, the housing 610 may include two scroll wheels and the housing 610 is moved over the surface to be cleaned by movement of the scroll wheels over the surface to be cleaned.

The housing 610 can define a receiving cavity for the cleaning head, the receiving cavity being located in a front half of the cleaning head (forward of the direction of movement of the wet surface cleaning apparatus when cleaning a surface to be cleaned) so as to receive the first stirring member 630 therein, the first stirring member 630 correspondingly being located in the front half of the cleaning head.

As shown in fig. 4, the housing 610 has a suction nozzle 620 formed thereon, and in this disclosure, the suction nozzle 620 is disposed adjacent to the first stirring member 630 and is located behind the first stirring member 630. In the present disclosure, the suction nozzle 620 is connected to the recovery line 401 and is formed as a start point of a recovery path.

The first agitator 630 is configured to agitate the floor surface to be cleaned; that is, when the wet surface cleaning apparatus is performing a cleaning operation or a self-cleaning operation, the first stirring member 630 can be driven to rotate by the first motor 650, whereby the first stirring member 630 can be in frictional contact with the floor surface to be cleaned and cleaning of the floor surface to be cleaned is achieved. During frictional contact of the first stirring member 630 with the floor surface to be cleaned, the cleaning liquid can be supplied to the first stirring member 630, thereby achieving wet cleaning of the floor surface to be cleaned.

In one embodiment, the first motor 650 may be disposed on the housing 610 and drive the first stirring member 630 to rotate by means of a synchronous belt transmission (i.e., operatively connected to the first motor 650); in another embodiment, the first motor 650 may be provided in the first stirring member 630 and can drive the first stirring member 630 to rotate; in the present disclosure, the first stirring member 630 is rotatable along a first axis; more preferably, the first axis may be a horizontal straight line of a lateral direction, i.e., a direction perpendicular to the front-rear direction; the front-rear direction is a moving direction of the surface cleaning apparatus when cleaning a surface to be cleaned.

The cover 640 is disposed on the housing 610 and configured to partially enclose the first stirring member 630; in one embodiment, the cover 640 is also formed as part of the receiving cavity. In other words, the cover 640 and the housing 610 together form the accommodating chamber.

The side cleaning assembly 660 is removably coupled to the housing 610 and is at least partially positioned below the housing 610; that is, at least part of the components of the side cleaning assembly 660 are located below the housing 610 and can contact the surface to be cleaned so that the side cleaning assembly 660 can also clean the surface to be cleaned.

Fig. 7 is an independent structural schematic diagram of a side cleaning assembly according to one embodiment of the present disclosure. Fig. 8 is a schematic structural view of a second motor according to one embodiment of the present disclosure.

More specifically, the side cleaning assembly 660 may include: the second motor 661, the second stirring member 662, the opening 666B, the scraper 666C, and the like.

In the present disclosure, the second motor 661 is provided to the housing 610 and is used for providing the second driving force; in a preferred embodiment, the second motor 661 may be formed inside the housing 610, thereby effectively preventing the damage of the second motor 661 by the liquid, and improving the cleaning efficiency of the wet surface cleaning apparatus.

More preferably, the second motor 661 may be connected with a decelerator 665 and connected with the second pulsator 662 through the decelerator 665 such that the second pulsator 662 has a proper rotation speed and facilitates the cleaning of the surface to be cleaned.

The second pulsator 662 is operatively connected to the second motor 661, and more particularly, the second pulsator 662 is operatively connected to an output shaft of the decelerator 665, whereby the second motor 661 can drive the second pulsator 662 to rotate.

More specifically, the output shaft of the reducer 665, i.e., the rotating component of the present disclosure, in one embodiment, the second motor 661 and reducer 665 can be disposed inside the housing 610; of course, the second motor 661 and the decelerator 665 may be provided outside the housing 610. In the present disclosure, the second motor 661 and the reduction gear 665 are disposed inside the housing 610.

At this time, the lower surface of the housing 610 is formed as a recessed area in which at least portions of the cleaning base 666 and the second stirring section 662 are located. Moreover, the rotating member, i.e., the output shaft of the reduction gear 665, can pass through the housing 610, at least partially below the housing 610.

More preferably, the cleaning base 666 is configured to be substantially parallel to the surface to be cleaned; accordingly, the second agitating part 662 is obliquely disposed.

Accordingly, the second pulsator 662 can be detachably coupled to the rotating member by a connector 667 and rotated by the rotating member.

Also, at least a portion of the outer edge of the second pulsator 662 protrudes from the sidewall of the housing 610 to be located outside the housing 610 of the cleaning head, that is, at least a portion of the second pulsator 662 protrudes to the outside of the housing 610 in the lateral direction, so that the parts such as corners of the wall, which cannot be cleaned by the wet surface cleaning apparatus of the related art, can be cleaned by the second pulsator 662.

In other words, even if the housing 610 is operated close to the wall or not, the second stirring member 662 can clean the corner portion, solving the technical problems set forth in the background art. At this time, the second agitator 662 may also be referred to as a side brush plate.

In the present disclosure, the second agitator 662 is provided to be rotatable along a second axis; wherein the second shaft is obliquely arranged; in this disclosure, the second shaft is angled from the vertical axis by 5-20 ° (e.g., the cleaning head of the wet surface cleaning apparatus is disposed on a generally horizontal surface to be cleaned) and such that the portion of the second agitator 662 that protrudes to the side wall of the housing 610 contacts the surface to be cleaned. In other words, the second stirring member is configured to be inclined inwardly by 5-20 ° with respect to the transverse direction of the cleaning head of the wet surface cleaning apparatus.

That is, the second shaft is not vertically disposed, and thus the second pulsator 662, which is located outside the housing 610 of the cleaning head of the wet surface cleaning apparatus, can be brought into contact with the surface to be cleaned, and accordingly, the cleaning base 666 or the like is not brought into contact with the surface to be cleaned, or the cleaning base 666 is spaced apart from the surface to be cleaned by a predetermined distance.

Considering that the first axis is a horizontal axis, the first axis and the second axis are formed at a non-right angle therebetween, that is, the first axis is not perpendicular to the second axis.

FIG. 9 is a schematic structural view of a second agitator and a cleaning base according to one embodiment of the present disclosure; fig. 10 is a schematic structural view of a cleaning base according to one embodiment of the present disclosure. Fig. 11 is a schematic view of another angled structure of a cleaning base according to one embodiment of the present disclosure.

The second pulsator 662 may include a hub 662A, a cleaner base 662B, and a side cleaner 662C.

The boss 662A may be made of engineering plastic or the like and has a certain hardness, so that the boss 662A is not easily deformed; in one embodiment, the hub 662A includes a disc and a rod member disposed at the center of the disc, wherein the rod member is removably insertable into the output shaft of the reduction gear 665, whereby the hub 662A is removable from the reduction gear 665 and, correspondingly, the second agitator 662 is also removable from the reduction gear 665.

The cleaning member base 662B is provided outside the boss 662A, and the cleaning member base 662B has a certain radial dimension, and the cleaning member base 662B has a hardness smaller than that of the boss 662A, and accordingly, the cleaning member base 662B is more easily deformed than the boss 662A; in a preferred embodiment, the cleaner base 662B may be made of rubber or silicone, etc., thereby enabling the cleaner base 662B and the side cleaner 662C to collectively apply a positive pressure to the surface to be cleaned.

The side cleaning piece 662C may be formed in the form of a lint, and it can be disposed at the outer side of the cleaning piece base 662B; in the present disclosure, the side cleaning member 662C can be sleeved on the outside of the cleaning member base 662B and at least partially positioned at the lower portion of the cleaning member base 662B, so that a surface to be cleaned, for example, a corner or the like, can be cleaned by the side cleaning member 662C.

In the present disclosure, the side cleaning assembly 660 includes a cleaning base 666, and in one embodiment, the cleaning base 666 can be detachably secured to the housing 610, for example, the cleaning base 666 can be secured to the housing 610 by screws, which are removed when the cleaning base 666 needs to be removed, i.e., removal of the cleaning base 666 is achieved.

The cleaning base 666 includes a semi-enclosed cleaning chamber within which at least a portion of the outer edge of the side cleaning elements 662C are located; also, since the cleaning base 666 can be detached from the housing 610, the second stirring section 662 can be detached; that is, the cleaning base 666 and the second agitator 662 can be independently removable from the cleaning head as a complete unit.

As shown in fig. 10 and 11, the cleaning base 666 may include a housing 666A, an opening 666B, a scraper 666C, a water outlet 666D, and the like.

In the present disclosure, although the cleaning base 666 is split into a plurality of parts, it should be understood by those skilled in the art that the cleaning base 666 can be integrally formed; for example, the cleaning base 666 may be made of a plastic material and integrally formed by injection molding or compression molding.

The housing 666A at least partially defines a semi-enclosed clean room for housing at least a portion of the second agitator 662; specifically, the housing 666A may include an upper member 6A1, a lower member 6A2, and a connection member 6A3; wherein the upper member 6A1 is disposed immediately adjacent to the lower surface of the housing 610 and can be fixed to the housing 610; in one embodiment, the upper member 6A1 forms a part of a positional flat plate shape, and may be of a fan shape as a whole.

The lower member 6A2 and the upper member 6A1 are arranged at an interval; accordingly, the lower member 6A2 is also provided as a plate-like structure, and may also be formed in a fan-like shape as a whole; the connecting member 6A3 is used to connect the upper member 6A1 and the lower member 6A2, and the upper member 6A1, the lower member 6A2, and the connecting member 6A3 together enclose the semi-enclosed clean room. At this time, the connection member 6A3 is circular arc-shaped as a whole and has a substantially uniform thickness, whereby the inner surface of the connection member 6A3 may also be arc-shaped so that there is a gap between the peripheral surface of the second agitator 662 and the inner surface of the connection member 6A3, that is, the connection member 6A3 does not affect the rotation of the second agitator 662.

The opening 666B is defined by at least a portion of the housing 666A; preferably, the opening 666B is provided in the connecting member 6A3 at a substantially middle position in the circumferential direction of the connecting member 6 A3. Those skilled in the art will appreciate that although not shown in the drawings, the opening 666B may also be provided in the lower member 6A2.

The lower edge of the opening 666B is flush with the inner surface of the lower member 6A2 or lower than the inner surface of the lower member 6A2, thereby facilitating the dirt such as liquid and solid trash on the inner surface of the lower member 6A2 to be sucked to the opening 666B and further to the recovery storage portion 400 via the opening 666B and stored in the recovery storage portion 400.

At least a portion of the scraper 666C is located within the semi-enclosed cleaning chamber and disposed adjacent the opening 666B; wherein said scraper 666C is arranged to interfere with said second stirring mill 662, whereby dirt (including sewage and solid waste) of the lower surface of the second stirring mill 662 can be scraped off by said scraper 666C, which accordingly also facilitates the entry of dirt into said opening 666B, since the scraper 666C is closer to the opening 666B.

In a specific embodiment, the scraper 666C is provided on the inner surface of the lower member 6A2 and extends to the inside of the semi-closed cleaning chamber by a predetermined height, that is, the scraper 666C extends to a direction approaching the upper member 6A1 by a predetermined distance so as to be able to protrude from the inner surface of the lower member 6A2, whereby the lower surface of the second stirring member 662 does not contact the lower member 6A2 but only contacts the scraper 666C when rotated.

More specifically, the scraper 666C includes an elongated blade provided in the radial direction of the second stirring member 662, thereby enabling the blade to have a short length.

As shown in fig. 11, at least part of one end of the scraper 666C is connected to the inner surface of the connecting member 6A3, so that the scraper 666C has high strength without being easily damaged; in addition, the scraper 666C includes a recess 6C1, and an inner wall surface of the recess 6C1, the connecting member 6A3, and the lower member 6A2 define a fluid flow through hole, that is, through which cleaning liquid on the other side of the scraper 666C (the opening 666B is located on the one side of the scraper 666C) can enter the opening 666B and be collected by the opening 666B.

In the present disclosure, the scraper 666C is located at a downstream side of the opening 666B in a rotation direction of the second pulsator 662, so that the opening 666B easily collects the dirt scraped by the scraper 666C.

The water outlet 666D is formed above the housing 666A for supplying the cleaning liquid to the second agitating member 662 in the semi-closed cleaning chamber, and further, the cleaning liquid can be supplied to the side cleaning member 662C of the second agitating member 662 so as to be thrown through the side cleaning member 662C to clean dirt on the surface to be cleaned.

In this disclosure, the opening 666B is in fluid communication with a suction device of the wet surface cleaning apparatus; more specifically, the opening 666B is connected to the recovery line 401 by a suction line 663, and thereby a negative pressure in the recovery line 401 is introduced into the semi-closed cleaning chamber, whereby suction of dirt within the semi-closed cleaning chamber is achieved, and accordingly fluid communication between the opening 666B and the suction nozzle 620 of the cleaning head is also achieved, wherein the suction line 663 is configured to form a gas passage between the opening 666B and the suction means of the wet surface cleaning apparatus.

In one embodiment, the side cleaning assembly 660 further includes a side fluid dispenser 664, the side fluid dispenser 664 configured to deliver cleaning liquid to the second agitator 662; in one embodiment, the side fluid dispenser 664 may be the water outlet 666D described above, in which case it is contemplated that the side fluid dispenser 664 is located on the side cleaning assembly; in another embodiment, the side fluid distributor 664 may be formed in a water outlet pipe or nozzle structure, the side fluid distributor 664 may be provided to the housing 610 and at least partially penetrate the housing 610 to be located below the housing 610, and the water outlet of the side fluid distributor 664 may be located above the second stirring part 662, whereby the side fluid distributor 664 may provide the cleaning liquid to the second stirring part 662.

More preferably, the water outlet of the side fluid distributor 664 is located at the downstream side of the scraper 666C in the rotation direction of the second pulsator 662, and accordingly, the cleaning liquid is supplied to the second pulsator 662 after the dirt on the second pulsator 662 is cleaned. For example, a portion of the outer edge of the side cleaning member 662C located within the semi-closed cleaning chamber interferes with the scraper 666C, whereby the side cleaning member 662C can be cleaned by the scraper 666C.

In one embodiment, the cleaning head of the wet surface cleaning apparatus may include a cleaning liquid pump 690, the side fluid dispenser 662 communicating with the cleaning liquid storage portion 300 of the wet surface cleaning apparatus such that the cleaning liquid within the cleaning liquid storage portion 300 can be provided to the second agitator 662 through the side fluid dispenser 662; more preferably, the side fluid dispenser 662 is connected to the cleaning liquid storage unit 300 through the cleaning liquid pump 690 described above, whereby the cleaning liquid is supplied to the second pulsator 662 after being pressurized by the cleaning liquid pump 690.

In the present disclosure, the cleaning liquid pump 690 may be a peristaltic pump, so that it is possible to control whether the cleaning liquid is supplied to the second pulsator 662 and, when the cleaning liquid is supplied to the second pulsator 662, to control the amount of the cleaning liquid supplied to the second pulsator 662 by controlling the start and stop of the cleaning liquid pump 690 and the rotation speed.

In one implementation, the cleaning liquid pump 690 may be one, i.e., the cleaning liquid pump 690 is capable of providing cleaning liquid to both the first agitator 630 and the second agitator 662; in another implementation, the cleaning liquid pump 690 is provided in two, i.e., includes a first cleaning liquid pump and a second cleaning liquid pump, wherein the first cleaning liquid pump and the second cleaning liquid pump are both connected to the cleaning liquid storage portion, and the first cleaning liquid pump is configured to provide cleaning liquid to the first stirring member 630, and the second cleaning liquid pump is configured to provide cleaning liquid to the second stirring member 662.

In the present disclosure, as shown in fig. 9, the hub 662A of the second agitator 662 includes a space therein through which the cleaning liquid is dispensed onto the side cleaner 662C. In a specific embodiment, the hub 662A includes a plurality of arms (extending radially) extending outwardly from the shaft, wherein the plurality of arms define the gap therebetween, whereby when cleaning liquid is provided to the hub 662A, the cleaning liquid can flow through the gap of the hub 662A onto the side cleaning members 662C located at the lower portion of the hub 662A.

Of course, the side fluid dispenser is also capable of supplying the cleaning liquid directly to the portion of the side cleaning member 662C located above the cleaning member base 662B and adsorbing the cleaning liquid to the lower portion of the side cleaning member 662C, i.e., to the side cleaning member 662C located outside and below the cleaning member base 662B, by the water absorption of the side cleaning member 662C.
