    SYSTEM AND AUTOMATIC METHOD FOR CLEANING CRYSTALS IN WINDOWS AND GLASSED FAÇADES
    DESCRIPTION
    The present invention is related to a system and an automatic method for cleaning windows and glass facades, and more specifically, to a system and method of the type that can be used in the cleaning of any type of glazing, window and / or windows. The present invention is especially suitable for use on the outside of any type of building due to the inherent difficulty in cleaning.
    State of the art
    At present, the cleaning of the glazing of skyscrapers and similar buildings is done through specially qualified employees, with a previous training of 18 months, who work as a couple on a mobile scaffold, and are practically hanging by a thread. Keep in mind that there are skyscrapers that reach more than 400 meters, such as the Burj Khalifa in Dubai of 828 meters, the Makkah Royal Clock Tower Hotel in Mecca of 601 meters, the One World Trade Center in New York City of 541 meters, the Shanghai Word Financial Center in Shanghai, of 492 meters, or the International Commerce Center, in Hong Kong of 484 meters
    The windshield wiper mechanisms of vehicles, trains, boats, trams or airplanes are also well known in the state of the art. It is a widely extended mechanism, which allows the vehicle's windows to be cleaned of water and dirt, considerably improving driving vision. However, its configuration consisting of an arm that can rotate in volume to one of its ends, and that has a long rubber edge attached to one of its sides, implies a pendular sweep on the glass, cleaning only the central part of the glass and leaving the upper and lateral edges uncleaned.
    Attempts have been made to develop some automatic glass cleaners for building glazing, but they incorporate rotary brushes or rollers with cleaning mechanisms.

    drive with lateral or perpendicular motors to the glazing, which prevent adaptation to recessed glazed holes, or involve controls and movement mechanisms in two dimensions, height and width, which increases their costs and limits their functionality.
    To solve the above problems, the document ES2529940 describes a configuration applicable to any glazing and comprising a carriage provided with sweeping motion on the plane of the glazing, and in which at least one brush in contact with the glazing is mounted , contact that is maintained during its sweeping movement, and that therefore effects the cleaning of said glazing. This document also incorporates a scrubber comprising cleaning liquid sprayers directed towards the glazing. However, this system cannot efficiently clean windows in tall buildings or houses with large windows, which are the type of buildings that most need an automatic cleaning system to avoid safety problems for cleaning workers when These work at height.
    Another document known in the state of the art is the international patent application number WO0101840 which describes an apparatus for cleaning a window comprising a windshield wiper and a belt and a zipper mechanism for moving the windshield wiper through the surface of window. This document also describes a hose that extends through the window frame and provides a means to transport a cleaning liquid from the inside of the window to its outer face. The windshield wiper can be activated without a motor, for example, by means of a horizontal bar through its inner face and by means of a belt and a cogwheel mechanism, the windshield wiper moves on the outer face of the window, cleaning it. Other similar documents describing similar systems are US2007044259 and EP0538521.
    On the other hand, WO2010019037 describes a window assembly comprising a frame and a window pane and at least one cleaning device for cleaning a face of the glass that includes means for moving the cleaning device in a direction of movement on the surface of the glass, in which the cleaning device has a dimension that corresponds at least substantially to the size of the window glass in a transverse direction

    Detailed exposition of the embodiments of the invention
    In the state of the art, a wide variety of windows are known according to their opening (sliding, practicable, swinging, pivoting, tilt-parallel, tilt-and-turn, fixed) in addition to the glazed facades, whether curtain wall or panel facade. Therefore, in the present invention the different configurations of a window have been taken into account so that the present invention can cover any type of window as well as it can be used in glazed facades.
    Practical realization for sliding and tilt-parallel windows
    In Figs. 1 to 7 shows the system object of the invention implemented in a sliding and tilt-parallel type window. More specifically, the system of the invention is composed of the following elements: a driving system (10), as shown in FIGS. 1, 2, 3, a cleaning element (20), as shown in FIG. 4, a hydraulic system (30), as shown in FIG. 5, a drying system (40), as shown in FIG. 6 and a protective cover (50), such and as shown in FIG. 7.
    As shown in FIGS 1-2, the drive system (10) is formed by the following elements: two electric motors (11) that rotate the sinfm screws (12) that are configured to transform the rotational movement of the motors (12) in an upward or downward movement of the assembly formed by the cleaning (20) and drying elements (40); a rectangular bar (13) to stiffen the assembly and accommodate the bearings configured to allow the rotation of the screw screws (12) and the assembly formed by the cleaning element (20) and the drying system (40).
    Thus, the drive system (10), when the electric motors (11) are operated, the sinfm screws (12) begin to rotate, which allows the assembly formed by the cleaning element (20) and the drying system (up and down) to be raised or lowered. 40) depending on the direction of rotation. The sinfm screws (12) are joined at the top by a bar (13) to give
    5
    10
    fifteen
    twenty
    25
    30
    35
    rigidity to the structure, which has two bearings installed to allow the rotation of the sinfm screws (12).
    On the other hand, and due to the difference in dimensions (ie they are not level) between the glass surface of a window leaf and the inner surface of the roof drawer (50) a solution has been devised by means of springs (15 ) which allows to obtain the two necessary positions:
    (i) that the cleaning element (20) is inside the drawer of the cover (50) so that the spring is compressed, as shown in FIG. 2 (a) and
    (ii) that the cleaning element (20) is in contact with the glass surface whereby the springs (15) will be extended, as shown in FIG. 2 (b).
    More specifically, the springs (15) are necessary as a suspension to allow total cleaning of the glass surface, as can be seen better in Figure 3. Thus, the problem solved by said springs (15) is that when the cleaning element (20) is rising, (and before a roller (21) that forms the cleaning element (20) finishes cleaning the entire surface of the glass, as will be explained later), the drying element (40 ) collides with the bottom of the bar (13) that joins the sinfm screws (12). This is due to the fact that the supports of the drying element (40) have had to be elevated (ie, raised) to be able to accommodate the cleaning element (20) when it is inside the drawer of the cover (50). Therefore, and thanks to the springs (15) when the drying element (40) comes into contact with the upper bar (13) of the structure, the springs (15) are compressed allowing to continue with the upward movement of the element of cleaning (20), solving the indicated technical problem.
    The cleaning element (20) is shown in detail in Figure 4 and as indicated above, it is formed by a rotating brush (21) that is responsible for the cleaning action and through which a glass cleaner product will circulate towards the glass surface. The rotating brush (21) also includes a nozzle to allow the glass cleaner product to enter; a first
    5
    10
    fifteen
    twenty
    25
    30
    35
    internal cylinder to fix the cleaning element (20) to the structure of the drive system (10); a second internal and perforated cylinder to allow the product to pass from the nozzle towards the outside of the rotating roller (21); a plurality of bristles or the like that will form the structure of the rotating brush (21) to clean the surface of the glass; and a cylindrical joint to allow rotation of the rotating brush (21).
    The hydraulic system (30) is shown in Figure 5. The hydraulic system (30) is composed of: a tank (31) for storing the glass cleaner product and / or water; a hydraulic pump to boost the flow of cleaning product; two hollow pieces (32) of cubic form to allow the flow of the flow to the nozzle of the cleaning element (20); a plurality of cylindrical ducts for connecting the system through which the glass cleaner flow circulates; and two gma channels (33) through which the water from the tank (31) circulates, from the upper end of the ducts to the hollow pieces (32) of cubic shape that rise and descend inside.
    Thus, the operation of the hydraulic system (30) is as follows: once the tank (31) inside the drawer of the cover (50) of glass cleaner product has been filled, the device is started and the pump starts to boost product flow through the ducts. This ascends to the highest part of the duct to be poured into the hollow part (32) of a cubic shape that moves through the guide channels (33). Said hollow parts (32) are attached to the nozzle of the cleaning element (20), so it is responsible for providing a constant flow of glass cleaner product to the rotating brush (21) that forms the cleaning element (20).
    The drying system (40), as shown in Figure 6, consists of:
    a) a main part that is attached to the drive system (10) by means of the springs. This piece is responsible for housing inside the piece that holds the tires as well as where both the limiting parts and the spring assembly are installed;
    b) six pieces for the suspension where the ends of the main piece are installed as well as the springs of the suspension;
    c) three springs to allow a slight vertical movement (suspension) of the main part when touching the bottom of the stiffening bar of the drive system (10);
    d) a piece where the tires are installed, together with the springs that the
    5
    10

    they expel and that has some grooves where the teeth of the limiting pieces fit when it is in a retracted position;
    e) two glass cleaner gums to remove excess product from the glass surface;
    f) eight springs to eject the piece that holds the tires;
    g) six limiting pieces whose teeth allow the horizontal movement of the piece that holds the rubber when it is being retracted but that fit into the grooves of the piece at the end of said movement; Y
    h) six springs for the limiting parts.
    The drying system (40), as shown in Figure 6, becomes operational when the upward movement of the drive system (10) is to end. At the moment in which this element touches the lower part of the stiffening bar of the drive system (10), a chain movement occurs that follows this order (see figure 6):
    i. The limiting parts compress the springs that keep them in their resting position, releasing the piece that holds the rubber bands (fig6a).
    ii. The springs of the piece that holds the rubbers extend by expelling it until the rubber touches the surface of the glass (fig6b).
    iii. The lateral ends of the piece that holds the rubber bands are introduced in the grooves present in the side bars of the roof that serve as gma during the downward movement (fig6c)
    iv. When the entire surface of the glass has been dried, the piece that holds the tires begins to retract and compress the springs because an inclination in the grooves transforms the downward movement of the drive system into a horizontal movement of the piece that holds the tires until its retracted position (fig6d)
    The protective cover (50) as shown in Figure 7 has the mission of protecting the system from corrosion caused by environmental dust and oxidation caused by rain or water used in the device itself. It has also been designed with the purpose of obtaining an aesthetic finish of the device so that
    5
    10
    fifteen
    twenty
    25
    30
    35
    this fits the window where it was to be installed. For this, said cover (50) consists of the following elements: an upper bar to protect the ball bearings at the upper end of the screw screws (12); a drawer at the bottom to store the cleaning element assembly (20) and the drying system (40) when it is not in operation. Said set enters and leaves the drawer thanks to a flip top. In addition, the electric motors are installed inside as well as the sealed tank (31) of the hydraulic system (30); and two side bars, one on each side, to protect the sinfm screws (12) and to serve as a gma channel to the part where the tires are installed.
    Realization for practicable, swinging, pivoting, tilt-and-turn and fixed windows.
    The design made for the case of practicable, swinging, pivoting, tilt-and-turn fixed windows, resembles the aforementioned case for sliding and tilt-parallel windows, although some modifications have been made regarding the drive system (10) and in the drying system (40).
    Unlike in the case of sliding and tilt-parallel windows in which the leaves move horizontally over each other, in the types of windows of this configuration there is no difference in dimensions (ie they are level) between the surface of the leaf glasses. This reason makes it unnecessary to introduce the system of springs present in the previous provision that allowed to achieve the two necessary positions of the drying system (40). Therefore, the drying system (40) will remain in an aligned position as shown in Figure 8.
    The above modification allows the suspension system to be removed as a suspension present in the drying system (40) of the previous practical embodiment. That is, only the springs that contribute to the suspension of the drying system (40) are eliminated but not the springs that have another function. This is because the drying system (40) is kept in a fixed position so it is not necessary to raise the level of the drying system supports (40) since they will not collide with the bottom of the bar (13 ) that joins the sinfm screws (12). For this reason, the components that make up the drying system (40) in this second embodiment are: a main body that is attached to the drive system (10) and inside which the part that holds the tires is housed as well as where they are installed both the limiting parts and the set of
    5
    10
    fifteen
    twenty
    25

    35
    springs that eject the gums; a piece where the tires are installed, together with the springs that eject it; some grooves where the teeth of the limiter pieces fit when in the retracted position; two glass cleaner gums to remove excess product from the glass surface; eight springs to eject the piece that holds the rubber bands; six limiting pieces whose teeth allow horizontal movement of the piece that holds the rubber when it is being retracted but that fit into the grooves of the piece at the end of said movement; and six springs for the limiting parts. Therefore, with respect to the previous embodiment, only the three springs have been removed to allow the suspension of the drying system (40).
    Realization for glazed facades
    The configuration designed for the case of glazed facades is composed of the elements that are detailed below. In this configuration, the drive system (10) is installed inversely to the two configurations described above, that is, the electric motors in the upper part and the bearings in the lower part of said system. This is because in this case the drawer of the cover that protects the assembly formed by the cleaning element and the drying system is located at the top of the facade.
    The quantity of components that make up this system is determined by the following conditions:
    - Number of motors, sinfm screws or bearings per facade = number of columns of windows + 1;
    - Number of rectangular bars or set (cleaning element (20) and drying system (40)) per facade = number of glass columns.
    Therefore, the drive system (10) in this third practical embodiment consists of: electric motors that rotate the sinfm screws; a rectangular bars to stiffen the assembly and accommodate the bearings; an assembly formed by the cleaning element and the drying system; ball bearings to allow rotation of the sinfm screws; Sinfm screws to transform the rotating movement of the motors into an upward or downward movement of the assembly formed by the cleaning (20) and drying (40) elements.

    35
    The cleaning element (20) in the three configurations is similar, the only difference in this embodiment for facades is the presence of two nozzles, one at each end, which are connected to the ducts, where the glass cleaner product circulates, through holes on the sides. The components that form it are the following: two nozzles to allow the glass cleaner product to enter; a rotating brush to clean the glass surface; an inner cylinder to fix the cleaning element to the structure of the drive system; and a perforated outer cylinder to allow the product to pass from the nozzle to the brush.
    In this embodiment the hydraulic system (30) comprises the installation of a tank on the roof of the building where the device is to be installed. This makes it possible to eliminate the pump that drives the glass cleaner product from the tank to the cleaning element, since the flow will circulate by gravity through a series of ducts and gma channels to the hollow cubic shaped parts that are connected to the nozzles of the cleaning element .
    The amount of gma channels or hollow cubic shaped pieces that make up the system is equal to the amount of glass columns + 1. Therefore, the hydraulic system (30) is composed of: a tank for storing the glass cleaner product; a plurality of hollow cubic shaped pieces to allow the flow of the flow to the nozzle; a series of conduits to connect the system through which the glass cleaner flow circulates; gma channels through which water flows from the ducts to the hollow cubic deformation pieces that rise and fall inside.
    The drying system (40) is the same as that used in the second configuration or embodiment (for fixed windows) discussed above but is now installed in the lower part of the assembly formed by the cleaning element and the drying system itself. Therefore, the system comes into operation when the downward movement of the drive system (10) will end. For this reason, the components that make up the drying system are: the main body that is attached to the drive system (10) and inside which the piece that holds the rubber is housed as well as where both the limiting parts and the assembly are installed of springs; four springs to eject the piece that holds the rubber bands; a piece where
    installed the rubber, together with the springs that eject it; some grooves where the teeth of the limiter pieces fit when in the retracted position; four limiting pieces whose teeth allow the horizontal movement of the piece that holds the rubber when it is being retracted but that fit into the grooves of the piece at the end of said movement; a glass cleaner rubber to remove excess product from the glass surface; Four springs for the limiting parts.
    The cover design (50) is different from the other configurations although it has the same functionality. The difference is that the aesthetic finish 10 is given greater importance since the installed device will have a great visual impact on the glazed facade. The quantity of components that form the cover is determined by:
    - Number of front bars per facade = number of glass columns
    15 + 1;
    - Number of drawers or lower bars per facade = number of columns of windows
    Said cover (50) consists of the following elements: drawers in the upper part 20 for storing the assembly of the cleaning element and the drying system when it is not in operation; a flip cover to allow the entry and exit of the assembly as well as supports where the electric motors are installed; a lower bar to protect the ball bearings at the lower end of the sinfm screws; and a plurality of front bars to protect the sinfm screws and to serve as a guide channel to the part where the tires are installed.
