Description

Wet surface cleaning system

Technical Field

The present disclosure relates to a multi-purpose wet surface cleaning apparatus and, more particularly, to a wet surface cleaning apparatus having a portable subassembly that is removably mounted on a support assembly.

Background

Wet surface cleaning apparatus are generally known in the art to be generally upright and are typically vacuum + water-cleaning wet surface cleaning apparatus. Upright wet surface cleaning apparatus generally comprise a cleaning base having a main body pivotally mounted thereto. Various components of the main body of the wet surface cleaning apparatus, namely the vacuum motor, supply tank, recovery tank, rechargeable battery, etc., may be mounted on the main body, which is pivotally mounted on the cleaning base, the back and forth movement of the cleaning base over the floor causing cleaning to be completed.

In recent years, a multi-purpose wet surface cleaning apparatus has emerged that combines a wet surface cleaning apparatus in a vertical orientation with a portable vacuum cleaner. Such a multipurpose wet surface cleaning apparatus may be used as a wet surface cleaning apparatus for wet cleaning floors, or a detachable portable vacuum cleaner may be used for cleaning surfaces above the floor, such as desktops, counter tops, curtains, etc. The multi-purpose wet surface cleaning apparatus includes a wet surface cleaning apparatus assembly and a dry vacuum cleaner assembly. The wet surface cleaning apparatus assembly and the dry vacuum cleaner are combined to form a generally upright wet surface cleaning apparatus, the wet surface cleaning apparatus assembly and the dry vacuum cleaner assembly being separable, the dry vacuum cleaner assembly including a suction power source and a rechargeable battery for use with a dirt cup or other cleaning accessory to form a single portable hand-held vacuum cleaner.

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. 1-3, the wet surface cleaning system 10 of the present disclosure may include a cleaning base 100 for contacting a floor, a support assembly 200 mounted on the cleaning base 100, and a subassembly 300 selectively mounted on the support assembly 200, the subassembly 300 being capable of being used independently when the subassembly 300 is removed from the support assembly, for example, as part of a self-contained wet surface cleaning apparatus, wherein the subassembly 300 is capable of being attached to an accessory such that the subassembly 300 and accessory form a wet surface cleaning apparatus; the cleaning base 100 when the subassembly 300 is mounted to the support assembly 200.

Fig. 4 and 5 are schematic structural views of a cleaning base according to one embodiment of the present disclosure. Fig. 6 to 9 are schematic structural views of a cleaning base according to another embodiment of the present disclosure. Fig. 10 and 11 are schematic structural views of a cleaning base according to a third embodiment of the present disclosure.

As shown in fig. 4 and 5, the cleaning base 100 is used for cleaning a surface to be cleaned, and the cleaning base 100 may include a cleaning module 110, and the cleaning module 110 may be driven to rotate so as to clean the surface to be cleaned by frictional contact between the surface of the cleaning module 110 and the floor to be cleaned.

In one embodiment, as shown in fig. 10 and 11, the cleaning module 110 may be formed in the form of a roll brush, for example, the cleaning module 110 includes a first power part 111 and a cleaning member 112; the cleaning member 112 is disposed outside the first power portion 111, for example, the cleaning member 112 is wrapped around the first power portion 111 and is rotatable together with the first power portion 111. The first power part 111 can be driven to rotate by the cleaning driving device 115, so that the cleaning member 112 rotates, and the cleaning of the surface to be cleaned is realized by the relative movement of the cleaning member 112 and the surface to be cleaned.

On the other hand, as shown in fig. 4 to 9, the cleaning module 110 may also be formed in a caterpillar structure, and in particular, the cleaning module 110 includes a first power part 111, a second power part 113, and a cleaning member 112, wherein the cleaning member 112 is formed as a ring member and disposed around the first power part 111 and the second power part 113.

In the present disclosure, as shown in fig. 6, 9 and 11, the first power part 111 and/or the second power part 113 can be driven to rotate by the cleaning driving device 115. Preferably, the first power part 111 is driven to rotate by the cleaning driving device 115, the second power part 113 is driven to rotate by the first power part 111 through a ring member, that is, the first power part 111 is formed as a driving roller, the second power part 113 is formed as a driven roller, and the cleaning member 112.

In the present disclosure, the second power unit 113 is located in front of the first power unit 111 with the moving direction of the wet surface cleaning system 10 when cleaning the surface to be cleaned as the front, and the outer diameter of the second power unit 113 is smaller than that of the first power unit 111, so that the wet surface cleaning system 10 can clean the corner and other components as much as possible.

The cleaning drive 115 may be a motor, such as a dc motor, preferably a dc brushless motor, a stepper motor, etc.

Further, the cleaning driving device 115 may drive the first power unit 111 to rotate through a speed change device 114, and the speed change device 114 may be located inside the first power unit 111 or may be located outside the first power unit 111. When the speed change device 114 is provided inside the first power part 111, the cleaning base part 100 can be made to have a small volume, and thus the wet surface cleaning system 10 can be adapted to clean a surface to be cleaned in a small space.

The cleaning drive 115 may drive the transmission 114 via a transmission assembly, which may be a belt transmission assembly, preferably a synchronous belt transmission assembly, a chain transmission assembly, a gear transmission assembly, or the like.

As shown in fig. 5, the cleaning base 100 may further include a fluid distribution module for supplying a predetermined amount of cleaning liquid to the cleaning module 110 or to a surface to be cleaned in the vicinity of the cleaning module 110 to supply the cleaning liquid to the surface to be cleaned by rotation of the cleaning module 110 so that the cleaning base 100 wet-cleans the surface to be cleaned.

In the present disclosure, as shown in fig. 4 and 5, the fluid dispensing module includes a liquid dispensing module 121 and a vapor dispensing module 122, wherein the liquid dispensing module 121 is connected to a second fluid connection interface 250, such as a liquid dispensing connection connected to the second fluid connection interface 250. In this way, the liquid dispensing module 121 is capable of receiving the cleaning liquid provided by the second fluid connection interface 250 and providing the cleaning liquid to the cleaning module 110 of the cleaning base 100 or to the surface to be cleaned in the vicinity of the cleaning module 110 of the cleaning base 100.

In terms of location, the liquid dispensing module 121 may be located inside the cleaning module or outside the cleaning module 110, for example, behind the cleaning module 110. And the outlet of the liquid dispensing module is located on or adjacent to the outer surface of the cleaning module.

The vapor dispensing module 122 is connected to the second fluid connection interface 250 or to the second thick film heater 125 of the cleaning base 100, for example, the vapor dispensing module 122 can be connected to the vapor dispensing connection of the second fluid connection interface 250, at which time the first thick film heater 480 can receive the cleaning liquid stored in the cleaning liquid storage 320 and heat the cleaning liquid and generate vapor that is provided to the first fluid connection interface, further, through the connection of the first fluid connection interface and the second fluid connection interface, to the vapor dispensing module 122, further, the vapor is provided by the vapor dispensing module 122 to the surface to be cleaned near the cleaning module 110 of the cleaning base 100.

On the other hand, the steam distribution module 122 may also be connected to the second thick film heater 125 and be capable of receiving steam generated by the second thick film heater 125, at this time, the second thick film heater 125 may be connected to the second fluid connection interface 250, for example, a liquid distribution connection portion connected to the second fluid connection interface 250, the cleaning liquid stored in the cleaning liquid storage portion 320 may be supplied to the first fluid connection interface 420, for example, the cleaning liquid may be supplied to the liquid distribution connection portion of the first fluid connection interface 420, and further supplied to the second thick film heater 125 through connection of the first fluid connection interface 420 and the second fluid connection interface 250, and of course, the cleaning liquid may also be supplied to the liquid distribution module 121.

As one implementation, the liquid dispensing module 121 may be a spray head or the like, whereby cleaning liquid can be sprayed onto the cleaning member 112 or the surface to be cleaned in the vicinity of the cleaning member 112. The steam distribution module 122 may include a plurality of spray holes positioned in front of the cleaning member 112, so that steam can be sprayed to the surface to be cleaned in front of the cleaning member 112 through the plurality of spray holes to soften stains on the surface to be cleaned by the steam, thereby improving cleaning effect of the cleaning member 112 on the surface to be cleaned.

In the present disclosure, as shown in fig. 5, the fluid dispensing module may further include a dispensing pump 124, the dispensing pump 124 may be a peristaltic pump or the like, whereby the pressure of the cleaning liquid transferred to the liquid dispensing module 121 may be increased by the peristaltic pump so that the cleaning liquid may be uniformly sprayed on the cleaning member 112 or the surface to be cleaned, and the cleaning liquid in the pipe line transferring the cleaning liquid may be prevented from flowing backward by the peristaltic pump so that the wet surface cleaning system 10 is safer to use. That is, at this point, the dispensing pump 124 can be connected to a second fluid connection interface, such as a liquid dispensing connection to the second fluid connection interface.

More preferably, as shown in fig. 5, the fluid dispensing module may further include a second thick film heater 125 to heat the cleaning liquid to steam by the second thick film heater 125 and provide the steam to the steam dispensing module 122; of course, the second thick film heater 125 may be replaced by other heaters. In the present disclosure, the second thick film heater 125 may also be connected to a second fluid connection interface, such as a liquid dispensing connection to the second fluid connection interface, by a dispensing pump 124. The dispensing pump 124 may be the same dispensing pump 124 as the dispensing pump 124 described above, or a separate dispensing pump 124 may be used; more preferably, when the same dispensing pump 124 is used, the piping between the dispensing pump 124 and the liquid dispensing module 121 is provided with a first switching valve, and the piping connecting the dispensing pump 124 and the second thick film heater 125 is also provided with a second switching valve, so that the cleaning liquid is controlled to be supplied to the liquid dispensing module 121 and/or the second thick film heater 125 by controlling the first switching valve and the second switching valve.

In the present disclosure, the pipeline between the vapor distribution module 122 and the vapor distribution connection part of the second fluid connection interface 250 may be provided with a third switch valve, and correspondingly, the pipeline between the second thick film heater and the vapor distribution module 122 is also provided with a fourth switch valve, so that different vapor supply modes can be selected by controlling the third switch valve and the fourth switch valve.

The first switch valve, the second switch valve, the third switch valve and the fourth switch valve can be electromagnetic valves or can be electrically operated to control the switch valves conveniently by a user.

When the fluid dispensing module includes a second thick film heater 125, cleaning liquid may be provided only to the cleaning base, in which case the dispensing pump 124 and the second thick film heater 125 may each be connected to a second fluid connection interface 250, wherein the second fluid connection interface 250 may include only a liquid dispensing connection.

Accordingly, when the fluid dispensing module does not include the second thick film heater 125, it is desirable to provide a cleaning liquid to the liquid dispensing module 121 and a vapor to the vapor dispensing module 122, at which point the second fluid connection interface 250 includes a liquid dispensing connection and a vapor dispensing connection, and accordingly, the liquid dispensing module 121 may be connected to the liquid dispensing connection and the vapor dispensing module may be connected to the vapor dispensing connection.

That is, the cleaning base 100 generates a recovery liquid, i.e., a cleaning liquid after use when the cleaning base 100 cleans a surface to be cleaned, and dirt, i.e., solid trash (e.g., dust, hair, etc.) on the surface to be cleaned, when the dirt suction module 130 is formed as a recovery inlet for the recovery liquid and dirt.

In one embodiment, as shown in fig. 7, the fluid dispensing module and the dirty suction module 130 are provided independently of each other, i.e. the fluid dispensing module is not integrated in the dirty suction module 130. Of course, the wet surface cleaning system 10 is also capable of dry cleaning a surface to be cleaned when the fluid dispensing module is not providing cleaning liquid to the cleaning module 110.

Preferably, the dirt suction module 130 is disposed behind the cleaning module 110 to facilitate recovery of liquid and dirt.

The cleaning base 100 of the present disclosure may further include a housing module 140, the housing module 140 forming at least a portion of an outer surface of the cleaning base 100. The front end of the housing module 140 is formed with the spray holes such that the front end of the housing module 140 is formed as a steam distribution module, but of course, the steam distribution module 122 may be formed as a separate component and mounted to the front end of the housing module 140.

The housing module 140 forms a receiving space, which may also be referred to as a brush chamber, in which the cleaning module 110 is located. When the suction source 330 is operated, the accommodating space communicates with the dirt suction module to form a vacuumized state, and the dirt on the surface to be cleaned and the cleaning module 110 is sucked to the recovery storage part 340.

The housing module 140 of the present disclosure can also provide support for the cleaning module 110, the fluid dispensing module, and the dirt suction module 130 described above, as well as for the cleaning drive 115, the transmission assembly, and the like.

The shunt valve 460 can be controlled by an actuator to switch among different fluid passages, in other words, the actuator can selectively block a line that supplies cleaning liquid, a line that supplies steam, or a line that supplies negative pressure to the cleaning base. For example, when the sub-assembly 300 is removed from the support assembly 200, the actuator is driven to block the line providing cleaning liquid, the line providing steam, and the line providing negative pressure to the cleaning base.

More preferably, the actuator is selectively engageable with the on-site signal of the subassembly 300 to block the line providing cleaning liquid, the line providing steam, or the line providing negative pressure to the cleaning base and direct fluid to the interface portion 390 after the subassembly 300 is disengaged from the support assembly 200.

Accordingly, the actuator is also able to selectively block the line supplying cleaning liquid to the accessory, the line supplying steam or the line supplying negative pressure, i.e. to block the respective sub-interfaces. For example, when the sub-assembly 300 is mounted to the support assembly 200, the actuator is driven to block the line providing cleaning liquid, the line providing steam, or the line providing negative pressure to the accessory.

In one case, the actuator can be engaged with an actuating portion of the connection end of the flexible hose, at which time, when the connection end of the flexible hose is connected to the interface portion 390, a line supplying cleaning liquid, a line supplying steam, or a line supplying negative pressure to the cleaning base is blocked, and fluid is guided to the interface portion 390.

In another case, the wet surface cleaning system 10 may include an in-place detecting device, which may be a hall sensor or a travel switch, etc., that is triggered when the sub-assembly 300 is mounted to the support assembly 200, at which time the actuator is driven to block a line supplying cleaning liquid, a line supplying steam, or a line supplying negative pressure to the accessory, and to open a line supplying cleaning liquid, a line supplying steam, or a line supplying negative pressure to the cleaning base 100; conversely, when the in-situ detection device is not triggered, the actuator is driven to block the line supplying cleaning liquid, the line supplying steam, or the line supplying negative pressure to the cleaning base, and to open the line supplying cleaning liquid, the line supplying steam, or the line supplying negative pressure to the accessory.

In the present disclosure, the bottom surface of the sub-assembly is formed in a substantially square or circular shape, and the first recovery connection part 410, the first electrical component 440, the first circuit interface 470, the second fluid connection interface 250, and the like may be disposed on the bottom surface of the sub-assembly 300.

Accordingly, the support platform 210 of the support assembly 200 is formed as an inverted cone-shaped body having a substantially square or circular cross section, and a lower end surface of the inverted cone-shaped body (i.e., a lower surface of the support platform 210) and an upper surface of the cleaning base 100 have a longitudinal interval therebetween, and accordingly, the second recovery connection part, the second electric element, the second electric circuit interface, the first fluid connection interface, and the like may be disposed at an upper wall surface position of the support platform 210.

The wet surface cleaning system 10 of the present disclosure, prior to operation, the subassembly 300 is operably mounted into the support assembly 200 or is separable from the support assembly 200 for use as a stand alone wet surface cleaning apparatus. When subassembly 300 is mounted to support assembly 200, various connections between component systems may be made simultaneously, including but not limited to fluid delivery interconnections, recovery interconnections, interconnections of electrical systems.

More specifically, when the subassembly 300 is operatively mounted to the support assembly 200, the cleaning liquid storage 320 is connected with the fluid dispensing module of the cleaning base 100 such that cleaning fluid (liquid and/or gas-liquid mixture) can be dispensed to the cleaning module 110 and/or the floor surface. The recovery storage 340 is connected to the dirty suction module 130 of the cleaning base 100 such that the vacuumized airflow generated by the suction source 330 is sucked into the recovery storage 340 through the dirty suction module 130. Moreover, the first circuit interface 470 and the second circuit interface 270 of the subassembly 300 are connected to transfer electrical energy to the cleaning drive, fluid dispensing module, or second thick film heater 125, etc. of the cleaning base 100.

In case that the commercial AC power is directly connected with the rechargeable battery module of the sub-assembly 300 through the power line and the AC/DC converter, so that the commercial power can simultaneously supply power to the cleaning base 100 and the sub-assembly 300, the AC/DC converter may be provided to the supporting assembly 200 to perform various cleaning functions.

The user fills the cleaning liquid storage part 320 by filling with at least one cleaning liquid. In order for the cleaning liquid storage part 320 to store the cleaning liquid, the cleaning liquid storage part 320 may be configured to be connectable with the first fluid by taking the cleaning liquid storage part 320 out of the sub-assembly 300, then filling the cleaning liquid storage part 320 with the cleaning liquid, and then mounting the cleaning liquid storage part 320 filled with the cleaning liquid to the side of the sub-assembly 300.

To operate wet surface cleaning system 10 in a floor cleaning mode, with sub-assembly 300 mounted to support assembly 200, a user actuates a main power switch on the handle or on the sub-assembly to power from a power source (such as a rechargeable battery module or a room electrical outlet of the sub-assembly) to power suction source 330 such that the negative pressure generated by suction source 330 generates a working air flow through recovery storage 340. Further, when the sub-assembly 300 is mounted on the support assembly 200, power is supplied to the cleaning base 100 through the sub-assembly 300. As described above, the circuit connection of the subassembly 300 and the cleaning base 100 is achieved by the mating first circuit interface and second circuit interface.

The power supplied from subassembly 300 can energize electrical components including first thick film heater 480, brush motor, brushless motor, PCB board, pump, illumination lamp, LED/LCD display screen, speakers, sensors.

In the on state with subassembly 300 on support assembly 200, the user grasps the handle and moves wet surface cleaning system 10 along the surface to be cleaned. By dispensing a cleaning fluid at normal or high temperature to the floor or cleaning base 100, the cleaning module rolls against the surface to be cleaned.

Cleaning fluid and suction power may be selectively dispensed by way of sensors interacting with the floor barrier, floor material, by way of, for example, visual sensors, ultrasonic sensors, TOF sensors, infrared sensors, etc. The used cleaning fluid and dirt on the floor surface to be cleaned are brought into the working air stream and removed by the dirt suction module on the cleaning base and pass through the fluid flow path into the recovery storage section 340, where the used cleaning fluid and dirt are separated from the working air, and the solid dirt and liquid dirt are separated by the solid-liquid separator in the recovery tank. The working air continues to flow out of the recovery storage 340 along the working air exhaust channel and to the suction source 330, and exhaust from the suction source 330 continues to flow out of the airflow outlet of the subassembly 300.

The user empties the recovery tank at the appropriate location by removing the recovery storage 340 from the side of the subassembly 300 to discard the used cleaning fluid and dirt into the appropriate container and drain.

To operate wet surface cleaning system 10 in a portable assisted cleaning mode, a user removes subassembly 300 from support assembly 200 by depressing a latch button on either subassembly 300 or support assembly 200.

The cleaning liquid reservoir 320, suction source 330, recovery reservoir 340, first thick film heater 480, etc. may all be in communication with the interface portion 390 of the subassembly 300 when used to remove the subassembly 300 from the support assembly 200. The first and second circuit interfaces of the sub-assembly 300 and the support assembly 200 are separated, thereby disconnecting the power to the cleaning base 100.

To prevent user mishandling, the suction source 330 is deactivated after the latch button is activated. And there is no fluid interaction between the second fluid connection interface 250 and the interface portion until the user installs the flexible hose on the accessory and presses the activation switch again.

When the sub-assembly 300 is required to operate alone, the user installs the flexible hose of the accessory to the interface portion 390 of the sub-assembly 300 and activates the switch, the interface portion 390 having fluid interaction therein and being capable of providing cleaning liquid and/or vapor, etc. to the accessory and drawing used reclaimed liquid and dirt from the accessory and to the reclaimed storage portion 340.

Thus, the wet surface cleaning system 10 of the present disclosure can be formed as a versatile wet surface cleaning system 10, providing unlimited potential for use with conventional upright wet surface cleaning apparatus. The subassembly is compact and lightweight, thereby simplifying use of the subassembly.
