Description

200902805 IX. Description of the invention: [Technical field to which the invention pertains] The present invention relates to #; a closed floor drain hole, and a type used for a bathroom, a temple, a toilet, a kitchen, or the like, or a floor drain. Water private, ^ water seal or set; trap ) 〇 [Prior Art] A problem with floor drains, which is even considered to be satisfactory, is the cleanliness of the floor drain itself. If the ground is kept clean, the risk is that the organic matter in the floor drain will decompose and stink. Blockage may also occur in the floor channel. The possibility of frequent cleaning and sweeping using chemical methods becomes difficult due to the water collector, and therefore the accumulation of aids. The use of a water collector in the floor drain is to avoid the escape from the air and taste into the living space. In the water collecting device), the outflowing water is forced to flow under a first mask, and the second mask flows above the 'the upper edge of the second mask is set to the lower edge of the cover' so that the remaining water will Avoid air passing. The two shrouds or shutters of the sump are also cleaned together with the water pipe, for example from the floor drain, which is more difficult to solve. It is known to provide a seal with an opening 'after the move, one can be The cleaning spiral brush is pushed in through it. But or the floor drain floor drain hole K (water to the unsatisfactory board drain is not accumulated, and is in the sediment, but the fouling. However, the Qing long organic pollution sewage system (after the scent seal is higher than the first one) Covering and staining. These openings are known for removing the seals.

200902805 Small and clean can be difficult and it can often be difficult to remove the seal. SUMMARY OF THE INVENTION It is an object of the present invention to provide an improved floor drain that reduces the sedimentation and stagnation of floating objects in the drain and thus remains cleaner and sanitary. The above object can be solved according to the first item of the patent application scope. Because the cross-section of the inlet stream is small, the water will flow at a considerable rate when it flows in, which causes light organic pollutants (that is, the problem) to be washed under the mask or lip that protrudes from top to bottom, and then The dammed up part of the rear water collector rises to the surface. In the water-blocking portion, which preferably has a large volume, the speed is lower than the inlet and the lighter organic material can rise to the surface, and then the organic material can flow along with the water extending from below. Two barriers or bounds, and crossed over to enter the exit. Preferably, the interior of the entire drain or drain hole, in addition to the inlet and outlet, is used as a water trap between the inlet and the outlet. On the whole, it is desirable to have a large amount of retained water in the floor drain so that the water does not evaporate and cause the sewer air to flow upward. The present invention thus produces a sanitary floor drain and is less susceptible to blockage than known floor drains and fully utilizes the available space of the sump. In a further development of the inventive concept, water is supplied from, for example, a bathtub or washbasin through a separate conduit, the lower end of which extends downward into the water. The large flow rate and flow rate of water from the bathtub can effectively flush the water collection 6 200902805. A further object of the present invention is to substantially promote the cleaning of the outlet pipe of the floor drain. This purpose is solved according to item 5 of the scope of the patent application. By setting the effluent barrier to the shape of the insert, it is easier to clean the outlet. It is also possible to manufacture floor drains in a practical manner. By arranging the outlet as a funnel-shaped member inside the floor drain, the outlet side wall constituting the water outlet barrier can be pulled up, even above the height of the outlet pipe, without reducing the flow profile, and from the floor drain Lightly floating material throughout the area (except the entrance) will still be transported to the exit where there is no barrier. This is because the current law specifies the minimum height between the lower entrance barrier or the lip and the higher exit barrier. The present invention allows for an elevated lower barrier, so the height of the bottom of the floor drain is also higher and the floor thickness is reduced. This in turn means that the floor drain according to the present invention can be applied to a thinner ceiling (floor). By further widening the outlet funnel, it can be used as an effective termination to prevent the insert from being pushed out of the outlet and to provide good grip when the insert is to be removed for cleaning. [Embodiment] As is apparent from the drawings, the main component 1 to which the floor drain is fixed includes an upper opening 2 and an annular flange 3 which projects radially outward from the upper opening 2. A step or shoulder 4 extending inwardly is provided directly below the opening 2, and a short cylindrical side wall 5 is disposed between the shoulder 4 and the opening 2. The fixing member 1 of the floor drain is gradually narrowed toward the flat bottom 7 of 7 200902805 by the lower member 6. Laterally, a horizontal line 8 is extended to connect to the sewage system. Above the shoulder 4, as shown in Figs. 4 and 5, staggered grooves 9 and portions 10 are provided in the rounded side wall 5. Figure 5 shows how a flooring material 11 (e.g., in the form of a plastic floor or some sealing layer) is disposed on the floor drain and 'the closure is folded or formed down into the floor drain' to make it The ridges 10 are in contact. The plastic floor 11 is pressed against the ridge 10 by a rubber clamp ring 12 which is pushed down into the floor sill and supported on the inside by a metal or plastic ring 13 and has a cross section. The clamp ring 12 is provided with a downwardly extending full-circle running bead 14 which is pressed down against a floor drain insert 15 and pressed against the jaw type disposed in the shoulder 4. ring. The floor drain is resting on the clamp ring or its support ring. The above-mentioned connection to the floor material 11 ensures that the outer rubber ring seal of the clamp ring 12 is tightly attached to the floor material ij surface, and is also connected to the floor drain channel disposed above the shoulder portion 4. 1 5, thus preventing water from entering between the floor material and the inside of the floor drain. 'The bead 14 and the floor material are pressed against the surrounding ridge 1 to prevent water from entering the floor and the floor material and the floor drain. In other words 'complete the two-stage seal. If desired, the cylindrical shape 5 can be manufactured to be slightly inwardly and upwardly inclined to ensure that the rear ring will be pressed down at any time. Alternatively, the rubber clamp ring, the crucible 2 may be shaped such that its upper edge is higher on the outer side. Therefore, when it is moved upward, it is attempted to become an extension of the other side of the ridge and the material channel L-shaped material. f. The beginning of the table into the object. This can be confirmed. Side wall, the clip makes it wider 8

200902805 is large to ensure stable installation and requirements for going out and down. The support ring 13 includes on its upper side a horizontal outwardly directed flange which acts as a contact member when the clamp ring 12 is depressed. The clamp ring is then mounted very tightly and the support ring 13 must first be pulled up to remove it. If the support ring _3 and the clamp ring 12 are vulcanized together, the clamp ring may have to be broken to release it. The rubber central ring 12 and the support ring 13 may be glued or vulcanized together, but preferably the two are separated. When the clamp ring (sealing rubber ring) is installed, it is preferably completed in such a manner that the support ring is inside thereof. In this way, the clamp ring presses against the floor covering during the downward movement and pulls it down against the floor drain cover. On the other hand, when the clamp ring is to be removed, the support ring is first removed, and the support ring is easier to grip and can withstand a larger pulling force than the clamp ring. Once the support ring is removed, the radial pressure on the clamp ring is reduced and the resilient clamp ring can then be removed to allow removal of the floor drain insert. The removal of the clamp ring therefore does not necessarily result in an undesired pull-up of the flooring material within the floor drain inlet. If the frictional force alone does not provide sufficient retention between the support ring and the clamp ring, it can be provided by matching grooves and ridges. The clamping ring, together with its clamping ring, resists upward thrust, and the clamping efficiency or latching force is quite large and exceeds the force of a person standing on the grid. Figure 18 shows another cross-sectional view of the upper portion of the floor drain main body. In Fig. 10, an inlet insert 15 for a floor drain is shown, which includes a funnel-shaped upper member 16. The upper end of the upper member 16 extends into a flat circular flange 17 which is intended, for example. Placed in the above clamp ring 1 2 9

Below the 200902805, a seal ring 18 is provided between the flange 17 of the insert 15 and the shoulder 4 (Fig. 5). The lower end of the funnel-shaped member 16 of the insert 15 extends into a vertical tube 19 in which a displaceable inner tube 20 is disposed, and a mounting seat 21 is disposed at the upper end of the tube 20, and A ball 22 is placed below the mount 21. The ball 22 and the mount 21 together form a non return valve by pressing the ball 22 with air and pressing it against the mount 21 by water in the sump. The tube of the ball mount is displaceable in the height direction for adjustment so that the ball can be pressed into the floor drain by the weight of the water in the funnel 16 without the water remaining beyond the edge of the floor drain. Road, but otherwise the ball 2 2 remains lifted by the water in the floor drain. The inner tube 20 is provided at its end with an outwardly facing flange 23 and is prevented from being pushed out of the outer tube 19 when it is overpressured in the effluent or in the sump. However, the tube 20 can be pulled down to ensure that the ball floats on the water (if, for example, a supplemental ring is used to raise the top of the drain channel). In this case, a distance member is provided between the outward flange 2 3 of the inner portion 20 and the lower end of the outer tube 19 to form a short tubular member 24 to prevent the inner tube from being raised. The tube is advantageously contoured to the supplemental ring of the floor drain. A seal ring is disposed between the vertical tube 19 and the inner tube 20 that provides the mount. In another embodiment, the mount may be an elastomeric material, such as rubber, and may in fact be responsible for the seal between the mount and the vertical tube 19. In the inner widening 25 of the flange 17 having the corresponding groove in the funnel-shaped member, an annular groove 26 is provided, and the inner portion is in. δ and the valve is borrowed from 21 22 pieces. In the department, the area is added to the Anga in 10

200902805 Its externally set one sleeve down 2 7 . The material inside the groove can be broken to provide a piercing opening through which the tubing 28 from the washbasin, shower, sink or bath can pass and push down with an intermediate seal. The tube is pushed down so that its lower end terminates below the horizontal plane 29, so that the connection (line 28) also constitutes an upper sump mask or lip. The water flows directly down into the floor drain, which is the exit side of the check valve formed by the ball and the mount. In this way, there is no risk of flooding the floor (when, for example, the bathtub water is missing). In addition, this fast flowing water supply effectively cleans the floor drain. It is of course also possible to integrate the check valve into an additional inlet from the bathtub or sink. In Fig. 6, a component 30 is shown which constitutes an exit limit (t h r e s h ο I d ) in the sump. This boundary member 30 is intended to be pushed into the outlet pipe 8 of the floor drain. The delimiting member 30 is substantially tubular and has a pair of outer sealing rings (or beads) 31 and the member is made of rubber or other resilient material. At its end facing the interior of the floor drain, the water tube extends into a terminal circular wall 32 which extends upwardly to an opening 33. The water thus flows over the edge of the opening 3 3 and exits into the outlet, and this portion, together with the portion of the water tube that extends downwardly from the funnel-like member, forms a sump that retains water in the floor drain. In Figures 12 and 13, another version of the bounding member is shown. The form of Figure 13 includes a rubber tube 35 provided with a sealing flange 34 and is semi-closed with a terminal 36 in its end facing the floor drain to form an outlet boundary for water. By manufacturing the delimiting member 11 200902805 3 0 or 35 with rubber or having a seal, and having an appropriate size, it can be easily removed when the outlet of the floor drain must be cleaned, and the cleaning work is It is particularly easy to make the entire profile of the outlet pipe easy to access. Figures 14a-f illustrate another outlet insert pattern having a generally flat funnel-like member disposed in the wide mouth of the floor drain and a conduit member providing a seal. The funnel member is wider than the outlet pipe profile to prevent the insert from being pushed out of the outlet and provides a good grip f to remove the insert for cleaning. By rotating the output sump parts, the level of the floor drain (if needed) can be adjusted to achieve the proper functioning of the check valve. In particular, the forms shown in Figures 12 and 13 provide substantial height adjustment. It is desirable to have a large amount of water in the floor drain to ensure that the sump does not dry out, and a check valve with a ball and mount type also contributes to this because there is no evaporation of water to the environment above the drain. Open water surface. Instead of placing the outer flange of the inlet funnel and the sump mask and check valve below the clamp ring, it may be considered to be placed on the clamp ring and held by a second clamp ring. This has the benefit of performing cleaning without the need to interfere with the clamping of the flooring material or the seal therebetween. In order to be able to clean without disassembling the clamping ring, it is conceivable to provide an opening which is in the upper collector part 15 and has a removable upper opening 3 3 of the limiting part 30 Rubber closure. The main advantage of the above-described sump parts is that they can be installed separately in many of the existing floor drains and drain holes, thereby improving their function and, in particular, greatly reducing the risk of water damage. 12 200902805 A conventional floor drain is shown in Fig. 1 having an upper lip 50, a lower boundary 51, and a dammed up volume 52 in the main floor drain member 53. Water can flow from the floor through the grid 5 4 or from the bathtub through the water pipe 5 5 into the floor drain. For example, light contaminants such as skin deposits and grease rise to the surface ' within the water holding volume 5 2 and remain on the top layer, and water can flow out of the upper lip 50 without interfering with the layer, after which the Limits 51. 〇 However, in the floor drain of the present invention, the light pollutants may be transported through the first lip into the waterblock due to the water velocity, and the flow rate in the water interception zone is slow, so the light pollutants may have time. The rise to the surface' is then washed away past the exit barrier and into the exit, maintaining the absence of organic matter inside the floor drain, otherwise the organic matter can cause odors and unhealthy decomposition of the inside. At the bottom 60 of the floor drain (figure 15 and 16), three (may be more) neotubes or adapters 61 are placed vertically downwards, or perhaps slightly offset from each other (these short tubes are cut to size) Therefore, the plastics of the type used for the installation of the conductive wires 62 can be embedded or can be embedded in the concrete pins. 'The installation of these short camps allows the height and angle of the floor drain to pass through the cut and can also be adjusted. The insertion depth of the short tube or the combined nail is adjusted. For this reason, some short longitudinal tubes integrated with the bottom may be provided as another type of selection, and the short tube may be disposed on the side of the floor drainage channel to be In this way, the adjustment span can be increased and there will be no need to cut off the short tube integrated with the bottom of the floor drain (if there is no space below). 13 200902805

l: Today's floor drains are usually held by wooden blocks that are placed just below the floor drain before the concrete. The concrete flow can be forceful and can easily wash away these blocks or other loose distance elements. Initially mentioned that the floor drain must meet some of the objectives, but with good functionality, not only need to add these features in any configuration, It should be associated with each other to provide optimal performance. The primary purpose of the floor drain is of course to drain without odor or bacteria, preferably even if the drain is not used for a long period of time. In addition, it is also hoped that the floor drains will be as smooth as possible, but if necessary, the least amount of trouble and damage can be done. The hope of one step is of course that no water will leak into the building. Recently, it has been turned to hope that the floor drain can resist high back pressure, so that the gas is not harmful to the sewage system. The check valve, together with the very attractive clamping ring, prevents the backflow of sewage into the floor drain and contaminates the floor and the floor above the floor drain. The floor drain of the present invention meets all of these requirements.
