Description

  The present invention generally relates to floorboard protection, more particularly horizontally adjacent to form a continuous floorboard system for receiving waste in various applications and industries such as but not limited to laundry and cooking facilities. The present invention relates to a self-cleaning type floorboard system including modules that can be connected to each other. The floorboard system of the present invention can also be formed as a permanent installation formed in a concrete floor by using a detachable male insert that repeatedly forms the shape of a drain pan. In addition, a floor grid covering the drain pan may be installed to support staff standing on it.

  The floorboard system of the present invention is suitable for use in dairy factories, meat processing factories, stables, poultry farms, machine factories, clean assembly rooms, printing facilities and food processing factories. Moreover, the floorboard system of the present invention can be used in transition areas for application of animal treatment. For example, the floorboard system of the present invention can also be used between a feed station and a dairy milking station, and the undesired residue (eg, fertilizer) can be removed from the hoof of livestock for later recovery as fertilizer. As it passes through the floorboard system, it is sprayed on the hoof of the livestock before it is passed into the dairy milking station.

  In many industries, it is important to keep certain facilities and rooms clean. For example, in the cooking industry, kitchen hygiene and cleanliness are important issues. In general, unnecessary items are often spilled on the floorboards of kitchens in restaurants, hotels, public facilities and commercial food sales facilities. Such unwanted items are in the form of spilled liquids, semi-solids or small solids and include grease, oil, water and various foods. Hot kitchens are a natural breeding ground for harmful bacteria, and these bacteria are easy to propagate in tile grout, pipes, drainage and other kitchen equipment, so spilled waste can cause hygiene problems There is also. Such kitchen fixtures are stationary and are difficult to keep clean if they cannot be maintained. Strict hygiene standards in most states require that kitchens in commercial food sales facilities be cleaned daily.

  Daily cleaning of walls, counter decks, appliances and floors involves time-consuming and labor-intensive hand work. In addition, waste can pose a health problem in that the spilled food is often moist or viscous and therefore has a high risk of kitchen personnel falling and injured. In addition, spilled grease or oil creates fire protection problems that require all work in the kitchen to be interrupted until removed from the floor. Predictably, interrupting all kitchen work in a restaurant or hotel results in significant revenue loss. In addition, current methods of cleaning facilities such as commercial kitchens may involve the temporary removal and / or disassembly of certain instruments and floorboard systems, followed by prolonged water cleaning. Of course, such cleaning methods use large amounts of water, which may increase water saving problems in certain regions.

  At present, there are well known floorboard systems in the prior art that are configured to address hygiene and safety concerns. One device in the prior art comprises a washable floor for collecting waste. This device is provided with a grid or mesh that a person stands on, which is mounted on a ground floor on which the waste falls. The ground floor is inclined downward toward the drain outlet. Flushing means are provided for washing away the waste liquid from the base floor to the drain outlet. The grid can be pivoted between a horizontal position and a vertical position and can be removed for easier maintenance. This device addresses some of the safety and hygiene issues mentioned above in that it provides a means of disposal for waste liquids, but the device must be specially ordered for a particular floor configuration. Lack of installation flexibility. Furthermore, the grid and ground floor are too heavy or too large for their parts to be individually cleaned by manual or mechanical means such as commercial dishwashers.

  Furthermore, another prior art device provides a support surface on which an employee can stand. This device allows water or fluid to flow through the support surface and under the modular floorboard member. The apparatus includes a series of transverse channels that form a fluid pad gridwork so that water flows under the modular floorboard. However, a significant disadvantage of this device is that the majority of the floorboard member's subsurface is in direct contact with the wet support floor. While this device addresses some safety issues in that it provides a non-slip surface on which personnel can stand, it has the problem of mold and deterioration of the underlying floor resulting from trapped water. Moreover, this device is not configured to be easily cleaned by manual or mechanical means. Finally, the device described above requires a large amount of water in order to thoroughly clean the device.

  Thus, there is a need in the field of floorboard systems for capturing waste that non-slip surfaces that reduce the risk of slipping and injury when an employee stands on top. There is also a need in the art for a self-cleaning floorboard system that can wash waste toward the drain so that it can be disposed of continuously. Further, there is a need in the art for a lightweight and small floorboard system that can be removed to facilitate cleaning with a cleaning device, such as a manual dishwasher or a commercial dishwasher installed in a commercial kitchen. .

  In addition, in this field, individual modules can be connected to each other for a desired area in the industry including, but not limited to, laundry facilities and cooking facilities such as cooking lines in commercial kitchens. There is a need for a modular floorboard system. Furthermore, in the field, there is a need for a floorboard system that is permanently formed in a concrete floor by using a removable male insert that repeatedly forms the shape of the drain pan, above the drain pan. A floor grate will be installed to support the staff standing on it. Such floorboard systems can be used in dairy factories, stables and meat processing plants, but are not limited to these applications.

  The present invention has been made in view of the above-mentioned concerns.

  The present invention specifically addresses the above deficiencies associated with floorboard systems and mitigates such deficiencies. More particularly, the present invention relates to an improved self-cleaning floorboard system for capturing waste. In one embodiment, the floorboard system is a modular assembly and is configured to be cleaned using typical cleaning equipment in the industry in which the floorboard system is installed. For example, if a floorboard system is installed in a commercial kitchen, such floorboard system is configured to be cleaned using a commercial dishwashing facility. In another embodiment, the floorboard system is cast in-situ into the concrete substrate using foam inserts, so that by hardening concrete, removing foam inserts, installing piping systems and laying floor grids, A durable floorboard system is provided.

  In accordance with an embodiment of the present invention, an automatic cleaning floorboard system for capturing waste is provided. The floorboard system comprises at least one module consisting of a drain pan and a floor grid. The drain pan includes a pair of inclined portions and a drainage channel centrally installed between the inclined portions. The drain pan has a pair of side walls and a pair of end walls. The inclined portions are disposed on both sides of the drainage channel and are inclined downward toward the drainage channel. The drainage channel extends between the end walls and inclines downward from one end of the drainage pan to the opposite end of the drainage pan toward the drainage port. The side wall and the end wall collectively form a peripheral edge of the drain pan, and extend upward from the inclined portion and the drain channel to surround the drain pan. The side walls and / or ramps are preferably at least one, such as discharge ports and / or injection nozzles, which discharge flushing liquid on the ramps, so that waste falling on the ramps is washed away towards the drainage channel A plurality of release mechanisms.

  The floor grid is configured to support personnel and / or animals that stand or move across it, and the waste is configured to pass through the floor grid. The side wall can also comprise a hollow passage having an inlet. Thereby, the flushing liquid is carried to the discharge port. Also, flushing liquid flows between them by the inlets of adjacent modules. The module located at the extreme end may be connected to a flushing liquid supply source. The inlet is connected to a fluid supply and flushing liquid is sent to the hollow passage. An overflow passage may be formed near the drainage channel to allow flushing liquid and / or liquid waste to flow between adjacent modules. The floor grid is composed of a plurality of adjacent floor grids arranged in parallel to each other. The floor grid is sized so that the overall length of the module matches the combined length of adjacent floor grids. The module may include a plurality of dowels, and the sidewalls include complementary openings dimensioned to receive dowels to interconnect the modules.

  The desired number of drain pans are assembled and joined in a horizontal direction using dowels or other suitable means. The inlet is connected to a flushing liquid supply source. During use, the flushing liquid flows from the inlet into the drain pan. It is also possible to supply the flushing liquid periodically using a time control valve. Further, the flushing liquid may be manually supplied as necessary when the waste has accumulated to the limit on the inclined portion. Furthermore, it is possible to operate the heat sensor and supply the flushing liquid to the inlet in the event of a fire. The flushing liquid may be water supplied from a tap water source and is discharged from the discharge port. The flushing liquid may be pressurized, and the flushing liquid may contain an additive such as an oil-based cleaning agent in order to easily decompose a specific food material.

  Waste that falls on the floor grid is washed away from the inclined portion toward the discharge path by the flushing liquid. When it reaches the discharge path, the flushing liquid then flushes the waste towards the outlet. A removable strainer tray may be used above the discharge path to prevent waste from entering the discharge path. It is also possible to install a discharge basket above the discharge port so that waste is not washed away into the discharge port. The floor grate is installed above the drain pan to support the staff standing on or working on the drain pan. The floor grid is preferably sized and shaped to prevent waste of a predetermined size from entering the drain pan.

  The features and advantages of the various embodiments disclosed herein will be better understood with regard to the following description and drawings. In the drawings, like numerals refer to like parts throughout the drawings.

  The present invention will be described with particular reference to the accompanying drawings. 1 and 2 show a module 12 of a floorboard system 10 in a first preferred embodiment for capturing waste. FIG. 1 is a perspective view illustrating a floor board system 10 according to the first embodiment, and illustrates a connection relationship of modules 12 that are adjacent to each other in the horizontal direction and that constitute the floor board system 10. The relationship between the drain pan 14 and the floor grid 24 constituting the module 12 is shown.

  1 and 2 show the module 12 with three floor grids 24 disposed on the drain pan 14, the module 12 may have at least one or any number of floor grids 24. . It is desirable that such floor grids 24 collectively cover the drain pan 14. Although the drain pan 14 is illustrated as having a substantially rectangular shape, it may be formed in any shape and size. Preferably, the drain pan 14 is configured such that the modules 12 are horizontally aligned and connected to each other. Each drain pan 14 is dimensioned and formed to be complementary to its shape.

  1 and 2, the drain pan 14 includes a drainage channel 40, a pair of inclined portions 16, a pair of side walls 26, and a pair of end walls 42. The inclined portions 16 are arranged on both sides of the drainage channel 40. As shown in FIG. 2, the inclined portion 16 is oriented so as to be inclined downward in the direction indicated by the arrow (ie, toward the drainage channel 40). The drainage channel 40 is disposed between the side walls 26 and extends therebetween.

  The drainage channel 40 may be configured to be inclined downward from the one end of the drainage pan 14 toward the opposite end of the drainage pan 14 toward the drainage port 18. The drain port 18 can also be connected to the drainage or sewage system of the facility where the floorboard system 10 is installed. A detachable drainage basket 78 can also be provided in the floorboard system 10 and installed above the drainage port 18 to prevent solid or semi-solid waste of a predetermined size from entering the drainage port 18. Also good. Alternatively, or in conjunction with a drain basket 78, another means for filtering waste by providing an elongated flat filtration mesh 62 along the drain 40 (shown only in FIG. 2). It is also possible to configure.

  As shown in FIG. 2, the drainage channel 40 may be inclined downward toward the central drainage port 18 in the middle along the drainage channel 40. In this regard, the drainage channel 40 may have two separate inclined surfaces that are inclined toward each other toward the drainage channel 40 installed in the center. However, a configuration of the drainage pan 14 in which the drainage channel 40 has only a single inclined surface is desirable. In this configuration, the drainage channel 40 is inclined downward from one end wall 42 of the drain pan 14 toward the other end wall 42.

  The drain port 18 is preferably disposed adjacent to one of the end walls 42. The end wall 42 and the side wall 26 extend upward from the inclined portion 16 and surround the drain pan 14. Similarly, the end wall 42 also extends upward from the drainage channel 40 and surrounds the drainage pan 14. In particular, each inclined portion 16 is formed with a plurality of discharge ports 22 configured to discharge or inject flushing liquid, so that waste is washed away from the inclined portion 16 to the drainage channel 40.

  As already mentioned, it is also possible to attach a floor grid 24 to each drain pan 14. In order to improve the detachability of the floor grid 24 and to facilitate cleaning and cleaning, the size (that is, the width) of the floor grid 24 is reduced so that a plurality of floor grids 24 arranged adjacent to each other can be drained. One of the pans 14 needs to be covered. For example, as shown in FIG. 2, three floor grids 24 are required to completely cover the drain pan 14.

  The floor grid 24 is preferably sized and configured to allow waste to pass therethrough and to support personnel, animals or other loads placed thereon. The floor grid 24 is supported at the peripheral edge of the drain pan 14 and may be attached to the wall 26 along a grid support notch 82 that extends along each side wall 26 in particular. In this regard, the floor grid 24 extends to the ramp 16 and the drainage channel 40 and is supported by the side walls 26. Optionally, the grid support notches 82 may be formed along each end wall 42 such that the furthest floor grid 24 is supported by the grid support notches 82 along the end walls 42.

  In the drawing, a drain pan 14 having a side wall 26 is shown, but the module 12 can also include a drain pan 14 that extends along the drain pan 14, ie, has a single ramp 16 that surrounds the drain pan 14. It is. In such a configuration, the inclined portion 16 defines a drain pan peripheral portion 20 that is inclined downward toward the drain channel 40. Further, the drain pan 14 may be configured such that the inclined portion 16 is inclined downward toward the drain port 18. The drain pan rim 20 can also include a plurality of discharge ports 22 spaced along the drain pan rim 20 to inject flushing liquid onto the ramp 16.

  In one embodiment, each sidewall 26 includes a hollow passage 28 formed therethrough through which flushing liquid flows. The inflow port 30 is formed in at least one end wall 42 and the side wall 26, and is configured to supply flushing liquid to the inclined portion 16 through the hollow passage 28. Further, in the embodiment in which the hollow passage 28 is omitted, the flushing liquid can flow into the inflow port 30 and be directly supplied to the inclined portion 16. However, the inlet 30 can also provide a conduit through which the manifold 94 passes and that delivers flushing liquid to the discharge port 22 or the injection nozzle 32.

  As shown in FIG. 1, the self-cleaning floorboard system 10 of the present invention includes a plurality of modules 12, and each module 12 is configured to be horizontally aligned and connectable to each other. The interconnections of the modules 12 are made using, for example, mechanical fixtures such as dowels 36 and an aperture 38 system, the dowels 36 being provided in one of the modules 12 to form openings formed in adjacent modules 12. Part 38 is received.

  However, the modules 12 can be connected to each other by various types of attachment mechanisms and are not limited by the specific embodiments and configurations shown herein. As shown in FIG. 2, the module 12 can include at least one strainer tray 74 that extends along the drainage channel 40, which can be mounted on the drainage channel 40. The strainer tray 74 is preferably configured to fit within the drainage channel 40 and acts to prevent waste of a predetermined size from entering the drainage channel 40.

  As shown in FIG. 2, the strainer tray 74 extends along the drainage channel 40, and is particularly configured to complement the two-stage inclined surface of the drainage channel 40. In this regard, the central thickness of the strainer tray 74 is greater than the thickness of the free end of the strainer tray 74. The strainer tray 74 may further include a lattice 76 that functions as a filtration mechanism so that waste does not enter the drainage channel 40. In the configuration in which the drainage channel 40 is formed as a single inclined surface inclined downward toward the drainage port 18 at one end of the drainage pan 14, the strainer passage is preferably configured to be complementary to the drainage pan 14. More particularly, when installed in the drainage channel 40, the strainer tray 74 is thicker at one end than at the opposite end so that the grid 76 mounted on the strainer tray 74 is positioned substantially horizontally. It is desirable to be formed.

  9-12, the self-cleaning floorboard system 10 of the present invention in an embodiment that can be installed on a substrate 88, such as a concrete substrate 88, is shown. As shown in FIG. 10, the drain pan 14 can be installed on a substrate 88 made of any composition, but it can also be installed on a setting bed of dry pack concrete. The peripheral edge of the drain pan 14 may include a peripheral flange 80 extending around it. This peripheral flange acts as a ledge that supports the drain pan 14. The peripheral flange 80 extends laterally outward from the side wall 26 of the drain pan 14. Preferably, the peripheral flange 80 is installed so as to be equivalent to the floor surface height 86. More specifically, the peripheral flange 80 of the drain pan 14 may be installed so that it is flush with the top surface of the floor finish 84 at a floor height 86, such as a floor tile or other floor finish 84. desirable.

  As shown in FIG. 10, the inclined portion 16 of the drain pan 14 may be formed on a substrate 88 such as a concrete substrate 88 that can be sequentially installed on a base surface such as soil or soil leveling 90. Next, the installation base can be sequentially stacked on the concrete substrate 88 and may be made of dry pack type concrete. Thereafter, the floor finishing material 84 such as a floor tile is sequentially installed on the installation base. The peripheral flange 80 can be installed on the installation base, and is preferably the same height as the floor height 86.

  The embodiment of the floorboard system 10 shown in FIGS. 9-12 is similar in configuration to that shown in FIGS. 1-2 and described above. More specifically, the drain pan 14 shown in FIGS. 9 to 12 may include a pair of opposing inclined portions 16 that incline downward toward the drain channel 40. However, each module 12 may consist of a drain pan 14 having a single ramp 16 with a drain port 18 disposed at the corner of the drain pan 14. The inclined portion 16 can be inclined downward toward the drain port 18. However, the structure shown in FIG. 1, FIG. 2, and FIGS. 9-12 which the drain pan 14 consists of a pair of inclination part 16 arrange | positioned at the both sides of the drainage channel 40 is suitable. As described above, the drainage channel 40 is inclined downward toward the drainage port 18 installed adjacent to the end wall 42.

  Still referring to FIG. 10, the size of the opening formed in the substrate 88 and the installation base is set to be slightly larger than the drain pan 14. More specifically, the opening includes an area where a piping system (such as a manifold 94 for flowing flushing liquid) can be installed after the concrete has hardened. When the piping system is installed, the drain pan 14 can be provided with a portion of the inclined portion 16 on the substrate 88.

  The drain pan 14 is then supported at its periphery by installation of dry pack concrete that forms the final installation base. In this regard, the dry pack type concrete fills the gap between the side wall 26 and the peripheral flange 80. The drain pan 14 can also be checked for levelness during operation of the floorboard system 10 to ensure proper functionality and fluidity of the flushing liquid. In order to level the drain pan 14 prior to installation of the installation base, it is also possible to provide a reinforcing bar.

  It is also possible to install the drain pan 14 in a building consisting of a plurality of floors, and a steel deck material can be used as the substrate 88. In this regard, the drain pan 14 may be provided with suitable notches so that the drain pan 14 can be mounted and supported on a steel deck material. The floorboard system 10 of the present invention can be installed by a method similar to the method of installing a floor sink or trough. The fixture can also be secured to the deck material prior to concrete pouring prior to installation of the drain pan 14. As stated above, it is desirable that the drain pan 14 be checked for levelness before pouring or hardening the concrete.

  After installation of the manifold 94 and the drain pan 14, an appropriate number of discharge ports 94, such as the injection nozzle 32, is located relative to the manifold 94 so that flushing liquid passing through the manifold 94 is discharged out of the injection nozzle 32. May be communicated. As shown in FIG. 11, the three injection nozzles 32 are provided on both sides of the drain pan 14 and extend through the inclined portion 16. The injection nozzle 32 may be screwed to the manifold 94. Three spray nozzles 32 are shown on each side of the drain pan 14, although any number can be formed.

  Further, as shown in FIG. 10, the injection nozzle 32 extends through the crease in the inclined portion 16, that is, the inclination changing portion, but can be installed along the inclined portion 16. Moreover, although the inclined portion 16 shown in FIG. 10 includes a two-stage inclined surface, the inclined portion 16 may be formed with a single inclined surface extending from the side wall 26 to the drainage channel 40. Furthermore, the inclined portion 16 may be curved, or is intended to include a surface that forms multiple angles or is inclined. However, in order to make it easy to wash away waste from the inclined portion 16 toward the drainage channel 40, a single or two-stage inclined surface is preferable.

  3, the longitudinal cross-sectional view of the module 12 in the 3-3 line of FIG. 1 is shown, and the inclination part 19 which inclines below toward the drainage channel 40 is illustrated. As shown, the inlet 30 allows flushing fluid to flow between adjacent modules 12 and the endmost module 12 in the floorboard system 10 is connected to a flushing fluid source. It is also possible to connect the inlet 30 to a fluid source, where fluid is conveyed to the hollow passage 28 or drain pan 14 via a manifold 94 or other similar piping system 96.

  The flushing liquid may contain an additive such as an injectable oil-based cleaning agent. The flushing liquid may consist of an aqueous or other liquid. For example, an oil-based cleaning agent may be supplied or injected into the flushing liquid in order to decompose grease adhering to the inclined portion 16. As shown in FIG. 3, the inlet 30 may be disposed on the side wall 26 and / or the end wall 42 and may be concentric with the hollow passage 28 so that fluid flows therebetween. If the hollow passage 28 is not included, the inlet 30 may be connected to a manifold 94 or other piping connection, and the discharge port 22 and / or the injection nozzle 32 receive flushing liquid therefrom.

  Next, in FIG. 4, an enlarged partial cross-sectional view of the module 12 of FIG. 3 is shown, and the connection state of the injection nozzle 32 in the side wall 26 is illustrated. As mentioned above, the injection nozzle 32 or the discharge port 22 may be disposed on or adjacent to the inclined portion 16. The discharge port 22 may be internally threaded to receive the injection nozzle 32 contained within the module 12. The injection nozzle 32 can also release flushing liquid at a high pressure level in order to enhance the effect of washing away waste from the inclined portion 16 toward the drainage channel 40. The injection nozzle 32 may be a conventional injection nozzle 32 or may be a water jet that is incorporated into the manifold 94 without any other injection nozzle 32.

  With respect to the operation of the discharge port 22 and / or the injection nozzle 32, the flushing liquid can be discharged therefrom manually or automatically. In the automatic operation type, the floorboard system 10 may be provided with a timer 70 in order to release the flushing liquid to the ramp 16 at regular or scheduled intervals. The injection nozzle 32 and / or the discharge port 22 can also be operated by a thermal sensor so that the flushing liquid is discharged in the event of a fire in a facility where the floorboard system 10 is installed. Still referring to FIG. 3, the drain pan 14 may include at least one overflow passage 48 proximate the drain passage 40 so that flushing liquid and / or liquid waste flows between adjacent modules 12. The overflow passage 48 is formed in the end wall 42 of the drain pan 14 and may be arranged so that a passage is formed through the overflow passage 48 when the modules 12 are connected to each other.

  As shown in FIG. 4, the drain pan 14 supports the floor grid 24 via a grid support notch 82 formed in the side wall 26. As shown, the grid support notches 82 are formed by defining a hollow passage 28 that extends along the side wall 26. Also, as shown in the preferred embodiment of FIGS. 9-12, the grid support notches 82 are formed in the sidewalls 26 by the edges of the floor grid 24 disposed along the grid support notches 82. At the lower peripheral edge of each floor grid 24, the side walls 26 and the floor grid 24 (i.e., grid grid 24) (ie, grid grid 24) so that the floor grid 24 is not located at an acute angle with respect to the radiused corners of the grid support notches 82. It is desirable to chamfer or round to form a gap with the support notch 82). Furthermore, the lower peripheral edge may be chamfered or rounded to form a gap so that waste can pass through.

  With reference to FIGS. 3-5, each drain pan 14 may include parallel spaced rib members 46 disposed along the drain pan 14 between the end walls 42. The parallel rib members 46 are laterally below the ramps 16 and drainage channels 40 to support the module 12 evenly on floors such as tiles and grout floors often found in commercial kitchens and other sales facilities. It may be arranged in the direction. Similarly, as described above, the floorboard system 10 that uniformly supports the drain pan 14 and the drainage channel 40 by utilizing the rib member 46 can be used in various applications and, although not limited to, a dairy factory. It can be installed at meat processing factories, poultry farms and stables.

  The drain pan 14 can be formed from any suitable material including metallic and non-metallic materials. With respect to metallic materials, drain pan 14 may be formed from stainless steel or other suitable metallic material that is resistant to corrosion and / or degradation due to environmental effects. For non-metallic materials, polymeric materials such as polyvinyl chloride (PBC) and / or polypropylene can be used.

  Furthermore, it is also possible to use glass fibers. In this regard, the drain pan 14 can be formed from any material that is suitable and compatible with the high temperatures that can be encountered when washing with a commercial dishwasher or the like. The drain pan 14 may be formed as a single structure by any method such as injection molding. More specifically, the side wall 26, the end wall 42, the drainage channel 40, the inclined portion 16 and the rib member 46, and the lattice support notch 82 and other elements of the drainage pan 14 are formed as a single structure. It is also possible to form by an injection molding process.

  When assembling, all corners can be rounded to prevent stress cracking caused by local stresses in the corners. Furthermore, since the drain pan 14 is easily cleaned by the rounded corners, waste accumulated in the corners that are difficult to reach can be more easily washed away and cleaned. The lower floor grid 24 can be rounded to complement any radial structure formed in the grid support notches 82 of the side walls 26a. In this way, the lower surface of the floor grid 24 contacts substantially adjacent to the sidewalls 26 and / or grid support notches 82.

  Next, in FIG. 5, the longitudinal cross-sectional view of the module 12 of 1st Embodiment in the 5-5 line of FIG. 1 is shown, and the drainage channel 40 which inclines below toward the drain port 18 is illustrated. In FIG. 5, the rib member 46 extends vertically downward from the inclined portion 16 to the lower surface. The discharge port 22 is disposed within and extends along the side wall 26. The discharge ports 22 are spaced evenly between the end walls 42, but can be spaced at any interval.

  The strainer tray 74 is disposed on the drainage channel 40 extending from one end wall 42 and reaching the other end wall 42, that is, installed in the drainage channel 40. As previously mentioned, the strainer tray 74 has a grid 76 that prevents solid or semi-solid waste from entering the drain 40. When waste enters the drainage channel 40, it may fall into the drainage port 18 and become clogged. As a final preventive measure, a detachable drainage basket 78 is arranged at the drainage port 18 so that solid waste does not fall into the drainage port 18 and does not clog downstream components such as grease traps. It is also possible to do so.

  1 to 5, 10, and 13, the floor lattice 24 includes lattice members 34 that are spaced apart and arranged in parallel, and these lattice members 34 are separated from each other in the lateral direction. Combined with. The interval between the lattice members 34 is desirably set so that semi-solid and liquid waste can pass but waste of a predetermined size cannot pass. As previously mentioned, the floor grid 24 is sized and configured to extend between the side walls 26 of the drain pan 14. Similar to the material used to form the drain pan 14, the floor grid 24 may be formed from a high strength material.

  For example, it is possible to assemble the floor grid 24 from glass fiber, and such material is lightweight so that it can be easily removed for cleaning of the floorboard system and cleaning of the floorboard grid 24, and further work and It is extremely strong structurally to support standing staff. The floor grid 24 can be formed of any material and any configuration that can sufficiently prevent the passage of waste of a predetermined size. Moreover, since the material used for the assembly of the floor grid 24 is compatible with commercial cleaning equipment such as a commercial dishwasher, it is also intended to withstand high temperatures. Embodiments of the floorboard system 10 may be of any size and shape. However, to facilitate the cleaning of the module 12, it is also intended that the width of the drain pan 14 and the floor grid 24 correspond to the cleaning equipment.

  Next, in FIGS. 6 and 7, a second embodiment of the self-cleaning floorboard system 10 is shown, which comprises at least one module 12 as described above, but with end-to-end It is desirable to have a series of modules coupled together. Each module 12 includes a drain pan portion 66 composed of a pair of first and second inclined portions 50 and 52, and a flow path portion 54 disposed between the first and second inclined portions 50 and 52. .

Similarly, the second inclined portion 52 is intended to be set to a size that facilitates cleaning. Accordingly, the floor grid 24 is dimensioned to be compatible with commercial cleaning equipment. In this regard, depending on the cleaning method, drain pan portion 66 and drain pan assembly 68 may be formed in any size and in any shape.

  As shown in FIG. 7, a vertically extending grid support 60 may be formed on the first and second inclined portions 50, 52 to support the floor grid 24. In an industry where a person is standing on the floor grid 24 for a long time, such a grid may be used to increase the comfort of a person standing on the floor grid 24 for a long time and to allow some flexibility in the floor grid 24. Support 60 may be restricted or removed at the same time. As shown, one of the drain pan portions 66 omits the use of a grid support 60, but the other one of the drain pan portions 66 to which the ends are coupled is illustratively shown. A floor grid support 60 is provided.

  Next, in FIG. 13, a floorboard system 10 in another embodiment is shown, and a drain pan 14 is formed or molded into a substrate 88 such as a concrete substrate 88. More specifically, the floorboard system 10 shown in FIG. 13 includes a drain pan 14 having features that are the same as or similar to the features described for the floorboard systems 10 of FIGS. 1-5 and 9-12. More specifically, the shape of the drain pan 14 is formed by the substrate 88, and the substrate 88 includes a pair of inclined portions 16 that are inclined downward toward the drain channel 40, and the drain channel 40 faces the drain port 18. And tilt down. In order to support the floor grid 24 on the upper surface of the substrate 88, the drain pan 14 forms a peripheral portion of the drain pan by a peripheral flange 80 formed around the drain pan 14.

  As shown in FIG. 13, the floorboard system 10 further includes a manifold 94 that extends along a portion of the drain pan 14 and is formed at one corner of the ramp 16. The manifold 94 extends along a part of the inclined portion 16, is disposed on the inclined portion 16, supplies flushing liquid to the inclined portion 16, and flushes waste to the drainage channel 40. The floorboard system 10 further includes an injection nozzle 32 that can communicate with the manifold 94 and that is operable to inject flushing liquid from the ramp 16 toward the drain 40. However, the injection nozzle 32 can be omitted. Instead, the opening 38 is formed in the manifold 94 to form a port for discharging the flushing liquid, and the flushing liquid is injected downward from the inclined portion 16. It is also possible to do.

  The shaped concrete system forming the floorboard system 10 of the present invention can be developed for use in any of the applications and industries described above. For example, molded concrete systems can be used in dairy factories, meat processing factories, stables and other facilities, and in applications that typically withstand severe wear to contact large animals. Other uses of the molded concrete system used in the floorboard system 10 shown in FIG. 13 include poultry farms, first aid rooms, machine factories, sterilization rooms, printing facilities, cooking factories and other industrial facilities. Furthermore, the floorboard system 10 of the present invention can also be used in transition areas for animal treatment applications.

  For example, the floorboard system 10 of the present invention may be used between a feed workshop and a dairy milking station. In this regard, the floorboard system 10 can be installed in a particular transition area and can also include a ground injection element that can be actuated by a hoof of livestock passing through the floorboard system 10. When the injection element is activated, as the livestock enters the dairy milking station, fluid is sprayed onto the livestock hoof and undesired residues (eg, fertilizer) are washed away from the livestock hoof to the floorboard system 10. An actuation mechanism may be included in the floorboard system 10 to actuate the injection element. Such an actuation mechanism may be configured as infrared that is actuated by a hoof of livestock.

  For the first application described above for the molded concrete system of the floorboard system 10, the manifold 94 and / or the injection nozzle 32 and / or the discharge port 22 that are typically used to flush the flushing fluid from the ramp 16 may be used by livestock. It can also be used to inject the hoof of livestock when crossing. In this way, by washing away the extra deposits and fertilizer that have adhered to the livestock yard from the hoof of the livestock, the sanitary condition and cleanliness of the facility where the floorboard system 10 is installed are improved.

  As already mentioned, in the dairy factory, the floorboard system 10 can also be configured to inject the cow's hooves when guiding the cow to a milking facility such as a rotary milking system. Advantageously, the floorboard system 10 as shown in FIG. 13 is installed as an on-site casting system in which the drain pan 14 is formed directly on a substrate 88 such as a concrete substrate 88. Ideally, the drain pan 14 is disposed in an area to be installed via a drainage channel 40 extending toward the drain port 18. Furthermore, the floor grid 24 for such applications can be appropriately sized and configured to withstand the weight of large livestock such as cattle. In this regard, the floor grid 24 can be as thick as 5.08 cm (2 inches) to increase load bearing capacity. As shown in FIG. 13, it is also possible to provide a floor grid support 60 in order to further constitute a support material for heavy loads.

  As shown in FIG. 13, the drain pan 14 may be formed on the substrate 88 by using a detachable insert configured as a male type that repeatedly forms the shape of the drain pan 14. FIG. 13 shows the installation state of one of the halved drain pans, the other being symmetrically formed along the vertical center line. However, the drain pan may be installed asymmetrically. As already mentioned, the male shape ideally includes the features described above with respect to the drain pans such as the side walls 26, the grid support notches 82, the ramp 16 and the drainage channel 40.

  The removable insert may consist of foam material, preferably molded as an integral foam member. Alternatively, the detachable insert is molded as a series of foam inserts 92, which are individual members that collectively shape the shape of the drain pan 14 when installed prior to flooring the substrate 88, such as the concrete substrate 88. It may consist of foam material. Installation of the floorboard system 10 is first performed by arranging and installing the drain pan 14 with reference to the drain port 18, and the drain port 18 is positioned approximately at the center of the drain pan 14.

  The foam is placed in the shape of a drain pan 14, after which concrete is poured around its insert. The foam insert 92 is removed immediately before or after the concrete is cured. Thereafter, the concrete is finally cured. As shown in FIG. 13, a recess is formed in the inclined portion 16 and receives a manifold 94 extending in the longitudinal direction along the inclined portion 16. The manifold 94 is connected to a flushing liquid supply source and injects the flushing liquid downward from the inclined portion 16. The grid support notches 82 are formed in the sidewalls 26 and are configured to be complementary to the thickness of the floor grid 24, particularly to support the floor grid 24.

FIG. 14 shows a piping system 96 connected to each other for a series of discharge ports 22 and / or injection nozzles 32 installed in a single part of the floorboard system 10. In FIG. 14, the floorboard system 10 includes two modules 12 that are end-to-end coupled, each module 12 having six discharge ports 22 and / or injection nozzles 32. The injection nozzles 32 on one side of the floorboard system 10 are connected in series. The schematic diagram of FIG. 14 illustrates a suitable assembly for a floorboard system 10 with 4 to 16 injection nozzles 32.

  FIG. 15 is a schematic diagram showing a piping system 96 according to another embodiment, and a pair of floorboard systems 10 are connected to each other with respect to the piping system 96 in parallel. More specifically, the piping system 96 supplies flushing liquid to the first floor board system 10 and the second floor board system 10 shown in FIG. The floorboard system 10 shown in FIG. 14 is similar to one of the floorboard system 10 pair of FIG. The flushing liquid may be supplied through the water supply pipe 100. Such water supply may be performed by the cold water supply pipe 100 having a diameter of about 1/27 cm in the standard supply pipe 100. However, the piping system 96 may include a water supply piping 100 having a diameter of 1.90 cm (3/4 inch).

  Although the water supply is performed at an arbitrary pressure level, it is desirable that the minimum static pressure of the water supply pipe 100 is about 2.84 mHg (55 PSI). However, it is desirable that a constant water pressure be applied to the floorboard system 10, and depending on the number of injection nozzles 32 and / or discharge ports 22 included in the floorboard system 10, the diameter and pressure level of the complementary water supply pipe 100. Should be provided. In order to apply an appropriate amount of pressure to the floor board system 10 and the piping system 96 along these pipes, the piping system 96 may be provided with a pressure supply source such as a pressure tank 72. In addition, the piping system 96 can include a pump to increase the pressure level of the flushing liquid supply.

  As shown in FIG. 14, the flushing liquid is supplied through a supply pipe 100 that leads to the shut-off valve 102 so that the flushing liquid can operate in a specific environment such as power loss. Further, in the same figure, a check valve 104 interposed between the pressure tank 72 and the shutoff valve 102 is shown to prevent the backflow of the flushing liquid. A solenoid valve 106 may be provided downstream of the pressure tank 72.

  This valve can be controlled by a timer 70 or a manual switch. The supply pipe 100 leading to the floor board system 10 is desirably a supply pipe 100 having a diameter of 1.90 cm (3/4 inch) in order to supply the flushing liquid having an appropriate flow rate to the floor board system 10. Each floorboard system 10 may have a header 98 disposed at one end thereof for connection to the piping system 96. As shown in FIG. 14, the spray nozzles 32 on one of the both side surfaces of the floorboard system 10 are desirably connected in series. It is also possible to provide a cap at the end of each of the series of discharge ports 22 and / or injection nozzles 32.

  FIG. 15 is a schematic diagram showing a pair of floorboard systems 10 installed in parallel. The piping system 96 supplies flushing liquid such as water to each floor board system 10. The components shown in FIG. 15 are similar to the components shown in FIG. However, the pair of solenoid valves 106 is provided at the branch point of the supply pipe 100. In particular, instead of connecting the discharge port 22 and / or the injection nozzle 32 in series, FIG. 15 shows another configuration in which three injection nozzles 32 are connected in parallel with another three injection nozzles 32. A cap may be formed at the end of each of the series of three injection nozzles 32.

  For drainage from drain 18, a 7.62 cm (3 inch) diameter coupling may be used to connect at least a 7.62 cm (3 inch) diameter waste conduit to each floorboard system 10. It is. As already mentioned, the drain 18 may lead to a grease trap. The timer 70 and the solenoid can be optionally provided in the floorboard system 10 and can be operated manually or autonomously. The timer 70 system may also have a manual control function so that the operator can further control the flushing liquid spray frequency.

  With respect to the pressure tanks 72, each pressure tank 72 produces about 11.36-15.14 l (3-4 gallons) of flushing liquid that can be pressurized to about 1.551-1.810 mHg (30-35 PSI). Thus, it is possible to provide a volume containing about 22.71 liters (6 gallons) of flushing liquid. Furthermore, another valve can be formed in the pressure tank 72 to control the operating pressure at which the pressure tank 72 operates. As already described, commercial degreasing agents and other additives can be injected into the piping system 96 supply piping 100 as shown in FIGS. 14 and 15 as necessary.

  Next, operation | movement of the floor board system 10 is demonstrated with reference to FIGS. The floorboard system 10 in FIGS. 1 to 2 is first installed with a drain pan 14 disposed on the surface to which the floorboard system 10 is attached. As already mentioned, such a surface may include a configuration of a concrete floorboard substrate 88 or steel deck material, although other configurations in which the floorboard system 10 is installed are contemplated. 14-15, after coupling the piping system 96, the piping system 96 is actuated to supply flushing liquid to the pressure tank 72 and then to a series of discharge ports 22 and / or injection nozzles 32. .

  Such an operation may be performed spontaneously by the timer 70 or manually by an appropriate staff member. During use, the waste falls onto the floor grid 24, passes through the floor grid and falls onto the ramp 16. At appropriate intervals or during manual operation, flushing liquid is discharged to the ramp 16 and, if a strainer tray 74 is installed, the waste is flushed to the strainer tray 74. The grid of the strainer tray 74 prevents waste of a predetermined size from entering the drain 40. The flushing liquid accumulates waste toward the drain port 18. The addition of drainage basket 78 further prevents such waste from entering drain 18 and clogging the grease trap.

  In the drain pan assembly 68 module 12 in FIGS. 3 to 7, the flow path portion 54 is coupled to the first and second inclined portions 50 and 52, and the end plate 64 is connected to the adjacent joint of the drain pan portion 66. After fixing, the piping systems are connected to each other. Operation and maintenance of the floorboard system 10 is similar to that described below with reference to FIGS. In the floorboard system 10 illustrated in FIG. 13, the drain pan 14 is installed using a foam insert 92 prepared on site. Next, the concrete substrate 88 is poured into the periphery. By removing the foam insert 92 and forming the concrete substrate 88, a drain pan 14 is formed having features similar to those described above with respect to FIGS. When the floor grid 24 is installed on the side wall 26, the waste falls onto the floor grid 24 and is washed away to the drain 18 in a manner similar to that described above.

  It is also possible to remove the floor grid 24 and manually water it with a hose, or clean it using a cleaning tool available in the facility, and perform maintenance management of the floor board system 10. For example, in a commercial kitchen, the floor grid 24 is cleaned daily with a commercial dishwasher so that it can be re-installed at any time. A commercial oily cleaning agent may be included in the flushing liquid and may be manually sprayed onto the grid 76 prior to cleaning to remove accumulated grease. In order to prevent the accumulation of grease in the inclined portion 16 and the drainage channel 40, other chemicals and additives may be injected into the supply pipe 100. Similarly, the strainer tray 74 and drain basket 78 may be cleaned and inspected.

  Various colored floor grids 24 may be utilized to facilitate monitoring of the wash cycle and replacement. For example, it is possible to use one color floor grid 24 for even numbered partitions and another color floor grid 24 for odd numbered partitions. When removing the floor grid 24, the discharge port 22 and / or the injection nozzle 32 can also be adjusted by checking the alignment to ensure that the injection nozzle 32 injects downward uniformly from the ramp 16. is there. In addition, various components of the piping system 96 such as the pressure tank 72, the shutoff valve 102, the solenoid valve 106, and the supply piping 100 are inspected.
