TECHNICAL FIELD
[0001] The present disclosure belongs to the technical field of energy saving and environmental protection, and particularly relates to a window washer.BACKGROUND
[0002] Glass doors and windows have been widely used in the construction industry for over a century, with enormous consumption. While offering excellent natural light and aesthetic appeal, they also bring a persistent headache: the daily chore of cleaning windows. Buildings proliferate and rise ever higher, and windows grow larger and more numerous. The attachment of dust and the accumulation of insect and bird droppings not only detracts from the aesthetic appeal of the environment, but also obstructs natural light and views, and even affects people's physical and mental health, making window cleaning a nuisance in daily life, work and study.
[0003] Conventionally, window cleaning has relied on manual wiping. Even for professional cleaning companies, the window cleaning tools are still rags, buckets, squeegees and safety accessories working in tandem. Without adequate safety protection measures, accidents involving window cleaners falling from heights occur from time to time, leaving psychological scars on people. The doors and windows can only be partially cleaned, leaving people with no choice but to clean only the interior side. With technological advancements and growing awareness of window cleaning, new tools like magnetic double-sided window cleaners and robotic window cleaners have emerged. However, none of these solutions can truly address people's practical needs. Window wiping requires constant cleaning and replacement of rags and pads, necessitating direct contact with dirty water. The dirty water on the glass surface is uncontrolled and simply flows downward. Repeated washing of rags, pads, cleaning tools and hands indirectly wastes significant amounts of water. Additionally, protection measures for windowsills and floors are required. Therefore, the conventional window cleaning is time-consuming, labor-intensive and water-consuming, and in some special operations, for the sake of safety, the glass may not be cleaned thoroughly.
[0004] In conclusion, the primary challenges in using existing window cleaning tools for door / window glass are as follows: there are potential safety hazards; contact with dirty water is unavoidable, and dirty water on the glass is uncontrollable; a large amount of water is consumed during the cleaning process; the cleaning process is time-consuming and labor-intensive; and the glass may not be cleaned thoroughly.SUMMARY
[0005] The present disclosure provides a window washer, including a water storage portion, a water pumping portion, and cleaning portions. The water storage portion includes a clean water storage portion and a dirty water storage portion. The water pumping portion includes a clean water pump-in portion and a dirty water suck-out portion. The cleaning portions each include a water-controlling and resistance-reducing structure and a magnet portion. With the window washer, water on the glass surface becomes controllable, and there is no need for rags or pads, revolutionizing the conventional window cleaning method. The cleaning operation for high-rise buildings can be completed indoors, making the door / window glass cleaning safe, environmentally friendly, water-saving, time-saving, labor-saving and thorough.
[0006] The present disclosure is implemented by the following solution: A window washer includes a water storage portion, a water pumping portion, and cleaning portions. The water storage portion includes a clean water storage portion and a dirty water storage portion. The water pumping portion includes a clean water pump-in portion and a dirty water suck-out portion. The clean water pump-in portion is in communication with the clean water storage portion through a water tube and a check valve and branches into two water injection tubes. The dirty water suck-out portion is in communication with the dirty water storage portion through a water tube and a check valve and branches into two water suction tubes. There are two cleaning portions having symmetrical and identical structures, and each cleaning portion includes a water-controlling and resistance-reducing structure and a magnet portion. The water-controlling and resistance-reducing structure is provided with a water sealing rubber ring, and the water sealing rubber ring is provided with a water scraping lip. The magnet portion is arranged in a bowl rim of the water-controlling and resistance-reducing structure. A plane of the magnet portion is provided with three ball rollers. Apexes of spherical surfaces of the three ball rollers are in a same plane. The plane of the apexes of the three ball rollers is parallel to the plane of the magnet portion and slightly higher than the plane of the magnet portion. A plane of the water scraping lip of the water sealing rubber ring is parallel to the plane of the apexes of the three ball rollers and slightly higher than the plane of the apexes of the three ball rollers. The water-controlling and resistance-reducing structure is provided with an air hole at a center position of a bowl rim and provided with a water injection tube perforation and a water suction tube perforation in a middle of an arc edge thereof. A water injection tube and water suction tube quick coupler is further arranged in the water-controlling and resistance-reducing structure. The water injection tube and water suction tube quick coupler is provided with a water suction port, a water injection tube quick coupling port and a water suction tube quick coupling port. The water-controlling and resistance-reducing structure is further provided with a handle and a water scraping strip. The water scraping strip is inserted into the water scraping strip fixing slot. A plane of a water scraping lip of the water scraping strip and the plane of the water scraping lip of the water sealing rubber ring are in a same plane. A back side of the water-controlling and resistance-reducing structure is provided with the handle and also provided with a water suction port position mark at a corresponding corner. The water injection tube and the water suction tube are respectively inserted into the water injection tube perforation and the water suction tube perforation of one of the water-controlling and resistance-reducing structures, enter the bowl rim of the water-controlling and resistance-reducing structure and are inserted into the water injection tube and water suction tube quick coupler.
[0007] When the window washer is used to clean door / window glass, the user may fill the clean water storage portion of the window washer with clean water and a proper amount of detergent. Then, the user may hold the handles of the water-controlling and resistance-reducing structures of the two cleaning portions and position the bowl rims of the water-controlling and resistance-reducing structures of the cleaning portions respectively to the two sides of the door / window glass to be cleaned such that the two cleaning portions can firmly attract each other through the magnet portions. At this time, the apexes of the spherical surfaces of the ball rollers on the magnet portion in each of the water-controlling and resistance-reducing structures are pressed against the glass surface, and the water scraping lip of the water sealing rubber ring and the water scraping lip of the water scraping strip are also pressed against and in contact with the glass surface. Next, the user may operate the clean water pump-in portion once such that 60 mL of clean water with detergent added is pumped from the clean water storage portion equally and respectively into the bowl rims of the water-controlling and resistance-reducing structures of the cleaning portions on the two sides of the glass. The water scraping lips of the water sealing rubber rings can prevent the water from overflow. The amount of water pumped is set such that the water can meet the use requirements but does not flow out through the air holes in the water-controlling and resistance-reducing structures. By pulling the handle of the water-controlling and resistance-reducing structure at the indoor side, the cleaning portions at the indoor side and the outdoor side can work synchronously with the aid of the magnetic attraction of the magnet portions, so that the indoor side and the outdoor side of the door / window glass can be cleaned synchronously. Because the ball rollers are in rolling friction with the glass surface and the water scraping lips of the water sealing rubber rings and the water scraping lips of the water scraping strips are chamfered, the resistance in the cleaning process is very small, thereby effectively preventing distortion of the water scraping lips due to large operating resistance and thus water leakage between the water scraping lips of the water sealing rubber rings and the glass surface. Moreover, the water scraping strips can remove water stains left by the water scraping lips of the water sealing rubber rings during operation. Upon the completion of cleaning, the user may operate the water-controlling and resistance-reducing structures of the cleaning portions such that the corners with the water suction port position marks are at the lower side. Then, the user may operate the dirty water suck-out portion once such that the dirty water is sucked out of the bowl rims of the water-controlling and resistance-reducing structures of the cleaning portions on the indoor and outdoor sides through the water suction ports on the water injection tube and water suction tube quick couplers and pumped into the dirty water storage portion.
[0008] When the window washer is used to clean the door / window glass in a closed environment, the cleaning portions of the window washer may be used separately to clean one side of the door / window glass. The specific operations are as follows. The water injection tube and the water suction tube of one of the cleaning portions may be blocked. The user may hold the handle on the water-controlling and resistance-reducing structure of the cleaning portion to be used and position the surface of the bowl rim of the water-controlling and resistance-reducing structure of the cleaning portion on the surface of the door / window glass to be cleaned. Then, the user may exert an appropriate pressure, such that the apexes of the spherical surfaces of the ball rollers on the magnet portion are in contact with and pressed against the glass surface and the water scraping lip of the water sealing rubber ring and the water scraping lip of the water scraping strip are also in contact with and pressed against the glass surface. Next, the user may operate the clean water pump-in portion once such that 30 mL of clean water is pumped into the bowl rim of the water-controlling and resistance-reducing structure of the cleaning portion, thereby meeting the use requirements. The water scraping lip of the water sealing rubber ring can prevent water from overflow and also prevent water from flowing out through the air hole of the water-controlling and resistance-reducing structure of the cleaning portion. By operating the handle of the water-controlling and resistance-reducing structure of the cleaning portion, the user can clean the glass surface under the action of the water scraping lip of the water sealing rubber ring. Moreover, the water scraping strip can remove water stains left by the water scraping lip of the water sealing rubber ring during operation. Upon the completion of cleaning, the user may operate the water-controlling and resistance-reducing structure of the cleaning portion such that the corner with the water suction port position mark is at the lower side. Then, the user may operate the dirty water suck-out portion once such that the dirty water is sucked out of the bowl rim of the water-controlling and resistance-reducing structure of the cleaning portion through the water suction port on the water injection tube and water suction tube quick coupler and pumped into the dirty water storage portion.
[0009] When the window washer is used to clean the door / window glass, for each piece of glass, 60 mL of water is consumed on average for both sides, 30 mL of water is consumed on average for one side, and the time consumed is 30 seconds on average. The cleaning operation for high-rise buildings can be completed indoors, making the operation process safe. Moreover, the window washer is environmentally friendly and water-saving, and can thoroughly clean the glass. Even if the window is equipped with a window barrier, as long as the gap between the window and the window barrier is not less than 7 cm, the window washer is available, thus thoroughly solving the problem of difficult window cleaning.BRIEF DESCRIPTION OF THE DRAWINGS
