Description

FIELD OF THE INVENTION

The present invention relates to washing devices for sweeping and washing a floor concurrently or for washing window glass in an electrically driven manner, and more particularly, to an electric sweeping washing device for sweeping the floor or a rug, scrubbing the floor and the rug, and washing windows concurrently.

BACKGROUND OF THE INVENTION

Due to technological advancement, there is wide use of the existing art pertaining to cleaning, an indoor environment, such as the floor, with an automated cleaning machine, wherein control logic of a mobile robot enables the cleaning machine capable of vacuum cleaning or floor washing to roam within a space to be swept and cleaned and clean the floor in an automated manner.
The aforesaid conventional automated cleaning machines fall into two categories, namely floor sweeping machines and floor washing machines. The floor sweeping machines remove dirt and dust from the floor by sweeping and vacuum cleaning the floor, but fail to remove dirt, dust, and smear from the floor or rug. Hence, it is necessary to remove dirt, dust, and smear with the floor washing machines.
However, according to the existing art, before its operation begins, automated floor washing machines require spraying a cleaning solution or clean water on the floor in an automated manner, scrubbing the floor with a roller brush, and collecting dirty water from the floor with a scraper installed behind the roller brush to thereby finalize floor washing. However, during the aforesaid cleaning process, as long as dirty water which results from scrubbing the floor remains on the floor, the floor will still look dirty after the dirty water has dried up, whereas a portion of the floor is likely to absorb water or has a crack, and in consequence dirty water will be kept inside the crack. Moreover, all the existing robotic floor washing machines assertedly have the capability of recycling 50% of the dirty water on the floor but leaving behind the other 50% of the dirty water on the floor. Hence, it is impossible to wash and clean the floor thoroughly. Since the rug absorbs water, water must not be sprayed on the rug; hence, it is impossible for the robotic floor washing machine to remove a smear from the rug.
Accordingly, it is imperative to provide a sweeping washing device whereby a user sweeps and washes the floor or rug simultaneously easily and quickly. The sweeping washing device is time-saving, labor-saving, cost-saving, and space-saving. Furthermore, with its brush being changed, the sweeping washing device functions as an electric window washer. The sweeping washing device not only precludes dirty water from landing on the floor but also leaves no dirty water on the floor and the rug.
The closest prior art is seen in US 2005/246853 . This document discloses:

An electric sweeping washing device, for washing a surface-to-wash, the electric sweeping washing device comprising:
- a sweeping washing brush, having:

  - a sprinkler head disposed on a side of the water absorbing scrubbing roller brush inside the sweeping washing brush casing and adapted to spray water on the water absorbing scrubbing roller brush;
  - a water absorbing part disposed on another side of the water absorbing scrubbing roller brush inside the sweeping washing brush casing and facing the water absorbing scrubbing roller brush to absorb water therefrom; and
  - a water collecting scraper disposed above the opening; and
- a water collection treatment structure, having:
  - a tank;
  - a clean water chamber disposed inside the tank and adapted to contain unused clean water; and
  - an air intake motor disposed at the dirty water chamber to reduce an internal pressure of the dirty water chamber to vacuum pressure, such that the used dirty water is raked by the water absorbing scraper and delivered to the dirty water chamber via the water absorbing tube.

SUMMARY OF THE INVENTION

From a user's perspective, conventional tools for use in washing windows, floors, and rugs are difficult to operate, time-consuming, and laborious, not to mention that they have to work in conjunction with various single-function machines.
It is an objective of the present invention to provide an electric sweeping washing device whereby a user sweeps and washes the floor and the rug easily and quickly, and in a cost-saving, labor-saving, and space-saving manner. Furthermore, the electric sweeping washing device removes smears, dirt, and dust from the floor and the rug while sweeping the floor and the rug, and may has its brush changed to thereby function as an electric window washer. The electric sweeping washing device precludes dirty water from landing on the floor.
In order to achieve the above and other objectives, the present invention provides an electric sweeping washing device for use in sweeping and washing a floor or rug. The electric sweeping washing device comprises a sweeping washing brush and a water collection treatment structure.
The sweeping washing brush comprises: a body having a separating board for demarcating and separating a sweeping washing brush front from a sweeping washing brush rear, wherein an opening of the sweeping washing brush front faces the floor or rug or is aimed at the dust collecting box, wherein an opening of the sweeping washing brush rear faces the floor or rug; a sweeping roller brush disposed inside the sweeping washing brush front, wherein both the sweeping roller brush and a water absorbing scrubbing roller brush are driven by a sweeping washing brush motor to rotate; an auxiliary wheel disposed at the body and between the sweeping washing brush front and the sweeping washing brush rear; the water absorbing scrubbing roller brush disposed inside the sweeping washing brush rear and driven by the sweeping washing brush motor to rotate; a sprinkler head disposed on a side of the water absorbing scrubbing roller brush inside the sweeping washing brush rear and facing the water absorbing scrubbing roller brush; and an water absorbing scraper abutting against another side of the water absorbing scrubbing roller brush inside the sweeping washing brush rear and abutting against the water absorbing scrubbing roller brush to absorb water therefrom.

The sprinkler head 130 is disposed on an inner side of the sweeping washing brush rear 111b. The sprinkler head 130 sprays water on the water absorbing scrubbing roller brush 120 to wash off dirt and dust otherwise adhered to the water absorbing scrubbing roller brush 120 as a result of scrubbing the floor and the rug, thereby keeping the water absorbing scrubbing roller brush 120 clean and wet enough to remove dirt, dust, and smears from the floor and the rug repeatedly.
The water absorbing scraper 140 is disposed on another inner side of the sweeping washing brush rear 111b to press against the water absorbing scrubbing roller brush 120 so as for the water absorbing scraper 140 to rake dirty water and dust on the water absorbing scrubbing roller brush 120. At the two ends of the water absorbing scraper 140 are buffer devices (not shown) which come in the form of springs or any other equivalent structures. The buffer devices are not regarded as an essential technical feature of the present invention and thus are not described in detail hereunder for the sake of brevity. While the water absorbing scrubbing roller brush 120 is rotating, the buffer devices adjust the degree of tight contact between the water absorbing scraper 140 and the water absorbing scrubbing roller brush 120, such that the water absorbing scrubbing roller brush 120 not only rotates smoothly but also functions well.
The water collection treatment structure 200 comprises a tank 210, a clean water chamber 220, a dirty water chamber 230, a pipe 240, a spray motor 250, and an air intake motor 260.
The clean water chamber 220 is disposed inside the tank 210 and contains clean water available for use.
The dirty water chamber 230 is disposed inside the tank 210 and contains dirty water which results from clean water usage.
The pipe 240 comprises therein a spray tube 241, a water absorbing tube 242, and a dust sucking tube 243. The spray tube 241 connects the sprinkler head 130 to the spray motor 250 and the clean water chamber 220.
The water absorbing tube 242 connects the water absorbing scraper 140 and the dirty water chamber 230. The dust sucking tube 243 connects the sweeping washing brush front 111a and the water absorbing tube 242 to the dirty water chamber 230.
The spray motor 250 is disposed in the tank 210 to withdraw unused clean water from the clean water chamber 220 with the spray tube 241. Then, the unused clean water thus withdrawn is driven and delivered to the sprinkler head 130 by means of the spray motor 250.
The air intake motor 260 is disposed at the tank 210 to reduce the internal pressure of the dirty water chamber 230 to vacuum pressure, such that the used dirty water is raked by the water absorbing scraper 140 and delivered to the dirty water chamber 230 by means of the water absorbing tube 242; meanwhile, dirt and dust is raked by the sweeping washing brush front 111a and delivered to the dirty water chamber 230 by means of the dust sucking tube 243 and the water absorbing tube 242.
The electric sweeping washing device 1000 sweeps and washes the floor 2 by following the steps described hereunder. The sweeping roller brush 160 is driven by the sweeping washing brush motor 121 to rotate and start sweeping the floor 2 and the rug; meanwhile, the water absorbing scrubbing roller brush 120 is also driven by the sweeping washing brush motor 121 to scrub the floor 2 or rug. Furthermore, the sprinkler head 130 sprays unused clean water on the water absorbing scrubbing roller brush 120 continuously to thereby rinse the water absorbing scrubbing roller brush 120. Furthermore, the water absorbing scraper 140 collects dust-containing and dirt-containing dirty water from the water absorbing scrubbing roller brush 120 and conveys the dirty water to the dirty water chamber 230 continuously. In so doing, the water absorbing scrubbing roller brush 120 is kept clean and wet all the time and therefore fit to clean the floor 2 or rug repeatedly.
Referring to FIG. 1 through FIG. 4, the user cleans the floor 2 or rug with the sweeping washing brush 100a by following the steps described hereunder.
First, the sweeping roller brush 160 sweeps most of the dust, dirt, and hair into the sweeping washing brush front 111a. Then, the dust, dirt, and hair ends up in the dust sucking tube 243 by suction, because the air intake motor 260 reduces the internal pressure of the dirty water chamber 230 to vacuum pressure. Afterward, the dust, dirt, and hair enters the water absorbing tube 242 and be mixed with the dirty water before being collected and stored in the dirty water chamber 230.
The water absorbing scrubbing roller brush 120 scrubs the floor 2 or rug to rake the dust and smears spared by the sweeping roller brush 160.
The clean water stored in the clean water chamber 220 is withdrawn by the spray motor 250 and delivered via the spray tube 241 to the sprinkler head 130, such that the sprinkler head 130 sprays the clean water on the water absorbing scrubbing roller brush 120 to thereby wash off the dust or dirt otherwise attached to the water absorbing scrubbing roller brush 120 as a result of its scrubbing the floor.
Due to the vacuum pressure generated by the air intake motor 260, dust-containing and dirt-containing dirty water on the water absorbing scrubbing roller brush 120 is raked by the water absorbing scraper 140 and delivered via the water absorbing tube 242 to the dirty water chamber 230.
Before starting to sweep and wash the floor and the rug with the electric sweeping washing device 1000, the user takes out the clean water chamber 220 and fills it with clean water.
When the clean water is going to run out and the dirty water chamber 230 is going to be full of dirty water, the user may take out the dirty water chamber 230 and empty it. In doing so, the sweeping roller brush 160 is capable of sweeping the floor and the rug continuously, and the water absorbing scrubbing roller brush 120 is kept clean all the time. A plurality of mobile rollers 270 is disposed at the bottom of the tank 210. The mobile rollers 270 enable the user to move the water collection treatment structure 200 of the electric sweeping washing device 1000 easily.

Hence, not only is the water absorbing scrubbing roller brush 120 cleaned efficiently, but the water absorbing scraper 140 can also remove and rake the dirty water on the water absorbing scrubbing roller brush 120 efficiently.
Referring to FIG. 6, there is shown a schematic view of the electric sweeping washing device 1000, wherein the brush is changed. The electric sweeping washing device 1000 is advantageously characterized in that the user can connect the sweeping washing brush 100 or the sweeping washing brush 100a to the pipe 240 and the water collection treatment structure 200 as needed.
In conclusion, the electric sweeping washing device of the present invention sweeps, vacuum-cleans, and scrubs the floor concurrently and thus speeds up the aforesaid cleaning process efficiently.
Furthermore, with the water absorbing scrubbing roller brush being clean and wet all the time, the user can sweep and wash the floor or rug easily, quickly, and in a labor-saving manner. Furthermore, with the electric sweeping washing device, the user performs floor sweeping and floor washing concurrently, thereby dispensing the hassle of operating various single-function floor sweeping devices, floor washing devices, vacuum cleaning devices, and rug cleaning devices; hence, the electric sweeping washing device is time-saving, labor-saving, and cost-saving. Furthermore, the electric sweeping washing device in operation prevents dirty water from landing on the floor; hence, not only does the floor thus swept and washed display no trace of residue, but the rug thus swept and washed also dries quickly to thereby extend its service life.

The spray motor 250 is disposed in the tank 210 to withdraw unused clean water from the clean water chamber 220 with the spray tube 241. Then, the unused clean water thus withdrawn is driven and delivered to the sprinkler head 130 by means of the spray motor 250.
The air intake motor 260 is disposed at the tank 210 to reduce the internal pressure of the dirty water chamber 230 to vacuum pressure, such that the used dirty water is raked by the water absorbing scraper 140 and delivered to the dirty water chamber 230 by means of the water absorbing tube 242. A plurality of mobile rollers 270 is disposed at the bottom of the tank 210. The mobile rollers 270 enable the user to move the water collection treatment structure 200 of the electric sweeping washing device 1000 easily.
The process of cleaning the window 1 with the electric washing device 2000 entails following the steps described hereunder. The water absorbing scrubbing roller brush 120 of the sweeping washing brush 100 is driven by the sweeping washing brushed motor 121 to scrub the window 1. The sprinkler head 130 faces the water absorbing scrubbing roller brush 120 and washes off dirt, dust, and dirty water otherwise adhered to the water absorbing scrubbing roller brush 120 as a result of scrubbing the window 1, thereby keeping the water absorbing scrubbing roller brush 120 clean and wet enough to remove dirt, dust, and smears from the window 1 repeatedly. The water absorbing scraper 140 presses against the water absorbing scrubbing roller brush 120 in order to rake dirty water, dirt, and dust and delivers to the dirty water chamber 230 the dirt and dirty water adhered to the water absorbing scrubbing roller brush 120 as a result of scrubbing the window 1. Hence, the water absorbing scrubbing roller brush 120 is kept clean all the time and thus fit to clean the window 1 repeatedly.
Referring to FIG. 7 through FIG. 11, there are shown schematic views of operation of the electric sweeping washing device according to the third embodiment of the present invention, wherein the sweeping washing brush 100 and the window 1 are shown.
