    Laundry detergents, cleaning methods and their use
    FIELD OF THE INVENTION
    The present invention relates to a gutter washer for cleaning trenches, such as drainage gutters in floors, in particular drain gutters covered with one or more grate elements.
    The invention also relates to a method for cleaning troughs, especially gutter-shaped floor drains.
    Finally, the invention relates to the use of a gutter washer for cleaning troughs, in particular drain gutters in floors, e.g. drainage gutters which are covered with one or more grate elements.
    BACKGROUND OF THE INVENTION
    It is known to use machines or hand-held tools for floor cleaning, especially in industrial cleaning.
    It is not uncommon for these machines or hand-held industrial cleaning tools to apply liquids and / or pressurized cleaning agents, e.g. up to 25 bar.
    Such tools usually employ water-based detergents. The detergents and / or rinse fluids, often water, are applied with machines or hand-held tools using nozzles to apply the water and / or detergents to the surface to be cleaned. Depending on their design, the nozzles may apply a layer of detergent to a surface, and / or they may generate a concentrated beam which, due to the working pressure, also causes mechanical influence on the surface, which contributes to an increased effect of the cleaning process.
    However, these machines are designed to efficiently clean large surfaces in a short period of time and are not suitable for cleaning trenches, including gutter-shaped floor drains, and especially drainage gutters covered with one or more grate elements.
    DK 2016 70643 A1
    The object of the invention
    It is the object of the invention to provide a gutter washer, method and use of the gutter washer that easily and efficiently cleans gutters, including in particular gutter floor drains.
    It is also an object of the invention to provide a gutter washer, a method and a use of the gutter washer which enables cleaning of gutters, especially gutter-shaped floor drains which are covered with one or more grate elements.
    It is also an object of the invention to provide a gutter washer, a method and a use of the gutter washer, which enables cleaning of gutter-shaped floor drains which are covered with one or more grate elements and at the same time have the underside of the grate elements cleaned without removing the grate elements.
    Description of the Invention
    These objects are achieved by a gutter washer according to the invention for cleaning trenches, such as drainage gutters in floors, in particular drain gutters covered with one or more grate elements. The gutter washer comprises an elongated handle in the form of a pipe element, which at the upper end is provided with connecting means for connection with a hose, for conveying cleaning fluids to the gutter washer, and which at its lower end is connected to a nozzle boom on which a , two or more nozzles, and wherein the nozzle boom is surrounded by a screen arranged for abutment against the top of the gutter and / or the upper side of the grating elements.
    This ensures that the cleaning fluid and / or the subsequent rinse liquid is directed down into the gutter and effectively cleans the gutter.
    The gutter washer is intended to be connected to a hose connected to a pumping station. The pumping station puts the cleaning fluids under pressure. In addition, the pump station may contain an injector system which mixes water, compressed air and detergent and generates a foam mixture which is applied to the interior surface of the troughs via the nozzles. Ordinary water or foam mixture is typically pressurized to 10-25 bar, preferably to 15-20 bar, if used for flushing in connection with flushing of the cleaning agent, e.g. the foam layer. In one variant, it is possible that the pump station
    DK 2016 70643 A1 can dispense a disinfectant, e.g. by mixing a concentrated disinfectant with water before laying.
    The gutter was provided at the upper end with connecting means for connection with a hose for conveying cleaning fluids to the gutter.
    Connecting means for coupling the gutter washer to the hose may be traditional hose couplings such as straps, studs and the like if a fixed connection is required between the gutter washer and the hose. However, it is preferred that the gutter washer and the hose be connected to a quick coupling / snap coupling. This means that the gutter was removable and thus easily replaceable, allowing the pump station to be used for other cleaning tools.
    The gutter washer comprises an elongated handle in the form of a pipe element. In the interior of the pipe, cleaning fluids are conducted from the hose down to the nozzle boom to perform the cleaning of the trenches.
    It is preferred that the tube is formed with a bend at a distance from the upper end. The buckle is made so that a blunt angle is formed between the upper and lower parts of the pipe. This allows the upper part of the pipe or a valve element coupled to this part of the pipe, e.g. on the coupling element, can serve as a handle for the person operating the gutter washer. This makes the washer ergonomic to use. Thus, the person operating the gutter was able to use it for a long time without experiencing any nuisance.
    The length of the pipe is adjusted so that the person operating the gutter washer can go upright while the screen is in contact with the grate and / or the upper edge of the gutter in the floor. Therefore, the length of the tubular handle is preferably 900-1400 mm and especially 1100-1300 mm between the nozzle boom and the bend above the handle. This further contributes to increased comfort for the user during the operation of the operator of the gutter washer.
    The gutter washer is connected at its lower end to a nozzle boom on which one, two, three or more nozzles are mounted. For example, be placed four, five, six, seven, eight or more nozzles on the nozzle boom, depending on the width of the nozzle boom. Dysebommens
    DK 2016 70643 A1 width is adapted to the width of the drainage gutter which is cleaned and is usually within the range 50-500 mm.
    The nozzle boom is also tubular, and the interior of the nozzle boom is in communication with the interior of the tubular handle for conveying the cleaning fluids through the interior of the gutter washer to the nozzles mounted in the nozzle boom.
    The nozzle boom is transverse to the tubular handle, preferably perpendicular to the tubular handle. The tubular handle is preferably mounted in the middle of the nozzle boom, in T configuration. Alternatively, the tubular handle is mounted at one end of the nozzle boom, in L configuration.
    The nozzles are positioned on the nozzle boom so that the nozzles are downward when the tubular handle is in its use position for a person of average height, thereby directing the nozzles into the gutter to be cleaned.
    The nozzles are preferably flat jet nozzles as they allow efficient dispersion of the cleaning fluids on the interior surface of the troughs. The flat jet nozzles are preferably rotated slightly relative to the longitudinal axis of the nozzle boom, preferably at an angle of 5-15 ° including 8-12 ° to avoid the scattering of the jets intersecting, as this may otherwise reduce the effect and thus the mechanical impact of the jets impact. against the inner surface of the gutter.
    The nozzle boom is surrounded by a screen arranged for abutment against the top of the gutter and / or the top of the grate elements. The screen helps to direct the cleaning fluid down into the gutter being cleaned and prevents splashes from spreading to the surroundings during the cleaning process itself, the prior and / or subsequent flushing / rinsing, which are described in more detail below.
    The shield is attached to the nozzle boom and / or to the tubular handle. It is preferred that the screen is pivotally mounted around the nozzle boom. Thereby, the handle and nozzle boom can be tilted relative to the screen as the lower edge of the screen rests against the edge of the gutter and / or the grate elements on the gutter. This automatically adjusts the angle between the screen and the handle to the height of the user, as users do not
    DK 2016 70643 A1 is so high can have a more pointed angle between the surface of the gutter and the tubular handle than a tall user. The screen is attached to the nozzle boom with traditional fasteners, e.g. screw connections that allow screen rotation relative to the nozzle boom. The screen is preferably attached to the ends of the nozzle boom and preferably through the end faces of the screen, see below.
    When the tubular handle and nozzle boom have T-configuration or L-configuration, as described above, the top of the screen includes an opening where the tubular handle passes through the screen. The opening is preferably elongated so that the tubular handle can be tilted relative to the screen and allow adjustment of the use position to the height of the user. In the T configuration, the opening will be located approximately in the center of the screen, and in the L configuration, the opening will be located near one side wall of the screen. If the tubular handle and nozzle boom are in L configuration, as described above, the opening may instead be located in one side wall of the screen for passage of the nozzle boom through the opening.
    The screen encloses the nozzle boom, and the lower edge is preferably located in the same plane, so that the bottom edge of the screen can abut the upper edge of the gutter and / or the upper side of the grating elements.
    The shape of the screen is not essential as long as it surrounds the nozzle boom. Thus, the screen may be formed with approximately vertical or inclined front wall and rear wall and with a caged surface therebetween. Alternatively, the screen has two or more sloping surfaces between the front wall and the rear wall covering the nozzle boom. To shut off the screen at the ends of the nozzle boom, the screen is designed with side walls at the ends.
    It is preferred that at least a portion of the lower edges of the screen be equipped with a flexible edge strip, which provides a good abutment against the edges of the gutter and / or the surface of the grating element. Thereby, a better abutment is achieved between the lower edges of the screen and the edges of the gutter and / or the surface of the grating element, and the risk of spraying the cleaning fluid from the gutter and / or spreading the cleaning fluid from the nozzles to the surroundings is reduced. The flexible edge molding is preferably formed of a suitable soft rubber type, e.g. ABS rubber (acrylonitrile butadiene styrene).
    DK 2016 70643 A1
    A valve may preferably be mounted at the upper end of the handle. The valve serves to interrupt the flow of cleaning fluids to the gutter washer and can at the same time serve as a handle for the user. The valve may be mounted on the gutter itself. In the preferred embodiment, the valve forms a separate part mounted on the hose at the pump station. This allows the gutter to disconnect the hose without the user having to interrupt the fluid supply at the pump station.
    Fasteners for mounting a handle are mounted on the upper portion of the tubular handle. The handle is preferably mounted perpendicular or approximately perpendicular to the tubular handle and preferably perpendicular or approximately perpendicular to the direction of feed. This provides the user with an effective grip on the gutter, making it easy to maneuver.
    The fastening means are, for example, a screw connection, a quick-release coupling, a snap-lock or the like, which cooperate with corresponding elements on or in the handle.
    The gutter was preferably provided with fasteners which allow mounting of the handle in both the right and left positions, allowing both right-handed and left-handed users to operate the gutter.
    It is preferred that the screen is equipped with at least two wheels, preferably four or more wheels at the lower edge of the screen, which ensures that the gutter washer can be easily and unobstructed across the gutter in the longitudinal direction.
    The gutter was preferably made of stainless steel and is therefore easy to clean. The wheels are preferably of a suitable plastic type, preferably a hard plastic type, e.g. polyester / PET, PE, PP or the like.
    The invention further relates to a method for cleaning troughs using a gutter washer as described above. The gutter washer is used for efficient cleaning of gutters, including preferably drainage gutters in floors, in particular drain gutters covered with one or more grate elements. The method comprises moving the gutter washer one or more times in a longitudinal direction of a gutter and on top of the gutter and / or on top of the gutter element (s) for laying a foam-shaped cleaning agent on the inner surfaces of the gutter, followed by one or more rinsing steps in which the gutter washer. is moved one or more times in the longitudinal direction of the gutter and on top of the gutter and / or on top of the gutter element (s).
    As mentioned above, the gutter washer is intended to be connected to a hose connected to a pumping station which pressurizes the fluids and generates a foam mixture which is applied to the inner surface of the gutter via the nozzles in the gutter washer.
    Preferably, conventional foaming industrial cleaning agents are used to generate the foam mixture which is laid out in the gutter. An example of a suitable foaming cleaner is Foam 42 from ITW Novadan.
    The foam is applied by advancing the gutter washer one or more times along the upper edge of the gutter, e.g. on top of the grate elements. For example, a layer of foam having a thickness of 5-25 mm, e.g. 10-15 mm, which will ensure that the foam layer does not disappear before the end of the impact time. The impact time is variable and depends on the foam layer and the degree of soiling of the gutter. The impact time is typically 5-20 minutes, such as 10-15 minutes.
    When the gutter is covered with grate elements, these are preferably not removed during cleaning. This causes the underside of the groove elements to be cleaned by backlash of cleaning, disinfection and / or rinsing fluid from the bottom and / or sides of the groove.
    The shape of the groove, combined with the supply of pressurized cleaning fluids from the nozzles, provides back spraying and deposition of foam-shaped cleaning agent or disinfectant on the underside of the grate elements. This effective dispersion of cleaning fluids to the underside of the grate elements is particularly pronounced and particularly smooth in U-shaped cross-sections, where the side walls are approximately vertical and the bottom is round and curved downwards. This means that the cleaning agents can be applied at a lower pressure to such renderings, which reduces the risk of accidental spreading of the cleaning fluids to the surroundings.
    DK 2016 70643 A1
    Also, some backlash of cleaning fluids will be observed to the underside of the grate elements in renderings of a different shape, e.g. rectangular cross-section or grooves with V-shape, V-shaped bottom or the like, but it may be necessary to increase the pressure to which the cleaning fluids are applied by ensuring a uniform spreading of the cleaning agents on the underside of the bottom of the grating elements in such grooves.
    It is preferred that the method comprises one or more prior rinse steps and / or prior or subsequent disinfection steps wherein the gutter washer is moved one or more lengthwise of the gutter and on top of the gutter and / or on top of the gutter element (s) during rinsing of the gutter with rinse liquid or spreading the gutter. a disinfectant in the gutter.
    Thus, in one variant, it is possible for the pump station to dispense a disinfectant, e.g. by mixing a concentrated disinfectant with water before placing in the gutter with the gutter washer. In disinfection, conventional disinfectants are used. An example of a suitable disinfectant is Oxivit active plus from ITW Novadan.
    The invention also relates to the use of a gutter washer according to the invention, which comprises an elongated handle in the form of a pipe element, which is provided at the upper end with connecting means for connecting a hose for conveying cleaning fluids and which at its lower end is connected to a nozzle boom on which one or more nozzles are mounted and wherein the nozzle boom is surrounded by a screen arranged for abutment against the top of the gutter and / or grate elements for cleaning troughs, such as drainage gutters in floors, in particular drain gutters covered with one or more grate elements.
    In this application, troughs are in particular drainage trenches in floors or other horizontal or approximately horizontal surfaces, in particular floor drains with drainage troughs covered with one or more grate elements arranged in the upper opening of the trough and in extension of one another.
