Description

FIELD OF TECHNOLOGY

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 and scrubbing the floor and/or rug concurrently and washing windows.

BACKGROUND

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 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 dust from the floor by sweeping and vacuum cleaning the floor, but fail to remove tiny dust and smear from the floor or rug. Hence, it is necessary to remove tiny 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 onto 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 claim 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 onto the rug; hence, it is impossible for the robotic floor washing machine to remove a smear from the rug.
The Electronic Sweeping Washing Device is a revolutionized floor, rug, and window washing machine. It can sweep and scrub on flat surface and rug concurrently for faster and cleaner result. The Electronics Sweeping Washing Device is time-saving, labor-saving, cost-saving, and space-saving. The Electronics Sweeping Washing Device offers changeable brush for floor and rug with option brush for window cleaner purpose. The sweep washing device is designed to clean with fresh water or wash fluid that spray over the brush surface and vacuumed out the dirty liquid directly to liquid container without landing dirty water to the washing area. For window cleaner simply uses option window brush to clean the windows or tiles.

Referring to FIG. 1 through FIG. 4, the user cleans the floor or rug 2 with the sweeping washing brush 100 a by following the steps described hereunder.
First, the sweeping roller brush 160 a sweeps most of the dust, dirt, and hair into the sweeping washing brush front 111 a. 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 a scrubs the floor or rug 2 to rake the dust and smears spared by the sweeping roller brush 160 a.
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 sprinkles the clean water onto the water absorbing scrubbing roller brush 120 a to thereby wash off the dust or dirt otherwise attached to the water absorbing scrubbing roller brush 120 a 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 a 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 a is capable of sweeping the floor and the rug continuously, and the water absorbing scrubbing roller brush 120 a is kept clean all the time. A plurality of mobile rollers 270 is disposed at the bottom of the tank 210.
