Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1-16, the double-sealing floor drain of the present invention comprises a casing 1, an upper cover 2 and a lower cover 3. The housing 1 has an integral structure, and includes a lower housing portion 12 (a portion below the bottom surface 115 in fig. 16) and an upper housing portion 11 (a portion above the bottom surface 115 in fig. 16), the lower housing portion 12 is provided with a lower water storage tank 102 along an inner wall, and the upper housing portion 11 is provided with an upper water storage tank 101 along an inner wall. Outer diameter D of lower housing portion 12 12 Smaller than the inner diameter D of the drain pipe 5 02 Outer diameter D of upper part 11 of housing 11 Is larger than the inner diameter D of the drain pipe 5 02 (see fig. 1, 6). When the housing 1 is installed at the water inlet of the water discharge pipe 5, the lower housing part 12 is inserted into the water discharge pipe 5, the lower water reservoir 102 is positioned in the water discharge pipe 5, the outer bottom surface 115 of the upper housing part 11 abuts against the pipe opening of the water discharge pipe 5, and the upper water reservoir 101 is positioned outside the pipe opening of the water discharge pipe 5 (see fig. 1 to 15). The upper water storage tank 101 is provided with an upper water outlet 116, the lower water storage tank 102 is provided with a lower water outlet 124, the upper sealing cover 2 is cup-shaped and is used for being reversely buckled at the upper water outlet 116 of the upper water storage tank 101 and forming a pipe external water seal (the upper water storage tank 101 is positioned outside the pipe orifice of the drain pipe 5, and the pipe external water seal is called as the pipe external water seal in the invention); the lower sealing cover 3 is cup-shaped and is used for being reversely buckled at a lower water outlet 124 of the lower water storage tank 102 to form a water seal in the pipe in cooperation with the lower water storage tank 102 (the water seal in the pipe is called as the water seal in the pipe because the lower water storage tank 102 is positioned in the water drainage pipe 5). The water seal outside the pipe cuts off the air flow with the ground, and the water seal inside the pipe cuts off the air flow with the drain pipe, so that the space R between the upper sealing cover 2 and the lower sealing cover 3 becomes a closed space. In the space R between the upper cover 2 and the lower cover 3, a multifunction lever 4 is provided. The double-seal floor drain provided by the invention has the advantages that the lower water storage tank 102 is arranged at a deeper part in the drain pipe 5 by utilizing the structure of the shell 1, the water storage depth and the water storage quantity of the lower water storage tank 102 are increased by utilizing the length of the drain pipe 5, the distance between the upper water storage tank 101 and the lower water storage tank 102 is increased, the limitation of the thickness of a building floor slab is avoided, and the multiple floor drains in the prior art are overcomeThe water seals are all arranged outside the pipe and adopt large plane size to influence the ground structure of the water outlet. In addition, the double water seal mode of upper and lower depth of the invention can prolong the distance of the water seal, and the upper sealing cover 2 and the lower sealing cover 3 have enough distance to form a space R to generate negative pressure, thus having better sealing effect compared with the prior art that multiple water seals are arranged at the position of the water outlet. Because lower water storage tank 102 sets up in drain pipe 5, the deposit water in lower water storage tank 102 can not receive the indoor environment influence, has avoided the interior water deposit of current water seal floor drain water storage tank to receive the ground air to flow the volatile defect of influence, can remain the water seal state throughout, guarantees lasting deodorant effect. The multifunctional rod 4 provided in the space R between the upper and lower sealing caps 2 and 3 may have various functions, and the upper end of the multifunctional rod 4 may be used to support the upper sealing cap 2 such that the upper sealing cap 2 is mounted at the upper water outlet 116 of the upper water storage tank 101 to be engaged with the upper water storage tank 101; the lower end of the multifunctional rod 4 can also be connected with the lower sealing cover 3 for installing, positioning and taking out the lower sealing cover 3 in the lower water storage tank 102; the multifunctional rod 4 can also be hung on the upper water storage tank 101 together with the lower cover 3, so that the lower cover 3 is positioned and installed at the lower water outlet 124 of the lower water storage tank 102 to be matched with the lower water storage tank 102. The multifunctional rod 4 is convenient to install and match the upper sealing cover 2 and the lower sealing cover 3 with the upper water storage tank 101 and the lower water storage tank 102 in a positioning manner, and particularly solves the problem that the lower sealing cover 3 cannot be installed, positioned and taken out when the lower water storage tank 102 is inserted into the drain pipe 5 deeply, so that the lower water storage tank 102 can be inserted into the drain pipe 5 deeply.
Referring to FIGS. 1 to 16, in the structure of the embodiment of the present invention, the distance H between the upper water outlet 116 of the upper water storage tank 101 and the lower water outlet 124 of the lower water storage tank 102 is the depth H of the upper water storage tank 101 11 2 to 6 times of the total weight of the composition. When the water flow is static, only air and no water exist in the space R. When the water overflows from the upper water outlet 116 of the upper water storage tank 101 and flows into the lower water storage tank 102, the water flows into the lower water storage tank 102 through the space R and then flows toward the drain pipe 5 from the lower water outlet 124 of the lower water storage tank 102. During the flow of the water stream, the space R is occupied by the water stream. When the flow of the water from the upper reservoir 101 to the lower reservoir 102 is completed, the flow of the water from the lower reservoir 102 to the drain pipe 5 is continued until the flow is completedThe lower reservoir 102 stops draining until the water level drops to the level of the lower outlet 124. From the end of the water flow from the upper water storage tank 101 to the lower water storage tank 102, the water level of the lower water storage tank 102 drops to the level of the lower water outlet 124, the water amount in the space R is gradually reduced in the period of time, and the space capable of containing air is gradually enlarged. The greater the distance H, the greater the negative pressure that occurs in the space R. When the value of H is the depth H of the upper water storage tank 101 11 2-6 times of the discharge pipe 5, the negative pressure internal absorption blocking effect is good for the odor in the discharge pipe 5 to leak to the ground, and the air in the space R cannot escape to the outside of the ground. However, the negative pressure is too high and the water seal outside the pipe or inside the pipe is easy to break through. Therefore, in combination with the practical applicability such as the requirement of spatial arrangement of the multifunction lever 4 and the installation length of the upright section of the drain pipe 5, the empirical value H = (2 to 6) H of the present invention 11 。
Referring to FIG. 16, the depth h of the lower sump 102 12 Depth h of upper water storage tank 101 11 . This allows the inline water seal of the lower water trap 102 to have a greater water depth and a greater amount of trapped water than the inline water seal of the upper water trap 101, with the resistance to gas flow through the inline water seal being greater than the resistance to gas flow through the inline water seal. When the negative pressure of the space R is overlarge, even if the water seal outside the pipe is broken down, the water seal inside the pipe cannot be broken down, and odor in the drain pipe 5 cannot be discharged upwards.
Referring to fig. 5, 11, 12, 15, 21, 24 and 25, the multifunctional lever 4 is provided with a multifunctional member. The multifunctional component can be an insect prevention plate or/and a slag blocking plate or/and a slag cleaning plate or/and a positioner or/and a gas mixing plate and the like, and can be used for preventing insects from passing through and crawling; the slag or mud can be prevented from falling downwards to block the lower water storage tank 102 and the drain pipe 5; can be used for removing deposited sludge; can be used for positioning the upper sealing cover 2 and the lower sealing cover 3 to prevent the left and right deviation under the impact of water flow; the water flow flowing downwards from the upper water outlet 116 of the upper water storage tank 101 collides and rubs with the air mixing plate to generate bubbles, so that the contact time and the contact area of the water flow and the air in the space R are increased, the air in the space R is mixed into the water flow more and is taken away by the water flow, and the negative pressure effect of the space R is enhanced.
Specifically, the insect-proof plate or/and the slag trap plate or/and the slag removal plate is a porous plate 41 or a mesh (not shown) mounted on the multifunctional rod 4 shown in fig. 5, 11, 15, 21 and 24, and the aperture of the porous plate 41 or the mesh can be determined according to the size of an insect-proof or slag trap object, and is generally less than or equal to 5mm; the positioner can be a support plate or bracket (not shown) with a diameter slightly smaller than the inner wall diameter of the lower housing portion 12 mounted on the multifunctional rod 4; the gas mixing plate can be a perforated plate 41, a mesh sheet or a spiral plate 43 as shown in fig. 12 and 25 mounted on the multifunctional rod 4.
Referring to fig. 1-27, the lower water reservoir 102 is an upwardly open annular groove formed along the lower portion 12 of the housing and formed by the bottom of the second inner ring 122 and the bottom of the second outer ring 121 sealingly engaging the second bottom plate 123. The outer diameter of the second outer ring 121 (also the outer diameter D of the lower housing portion 12) 12 ) Is smaller than the inner diameter D of the drain pipe 5 02 . The upper water storage tank 101 is an annular groove which is arranged along the upper part 11 of the shell and is provided with an upward opening and is formed by the sealing connection of the bottom of the first inner ring 112 and the bottom of the first outer ring 111 with the first bottom plate 113. The outer diameter of the first outer ring 111 (also the outer diameter D of the housing upper part 11) 11 ) Is larger than the inner diameter D of the drain pipe 5 02 . The upper water storage tank 101 and the lower water storage tank 102 are disposed vertically, and the centers of the upper water storage tank 101 and the lower water storage tank 102 are on the same axis. The distance H between the lower water outlet 124 of the lower water storage tank 102 (the top surface 1221 of the second inner ring 122) and the upper water outlet 116 of the upper water storage tank 101 (the top surface 1121 of the first inner ring 111) is the depth H of the upper water storage tank 101 11 2 to 6 times of the total weight of the composition. The distance between the lower water outlet 124 of the lower water storage tank 102 and the pipe orifice of the water drainage pipe 5 is H- (H) 11 + the thickness of the first bottom plate 113), the depth of the second bottom plate 123 of the lower water reservoir 102 in the drain pipe 5 is H- (H) 11 + the thickness of the first base plate 113) + h 12 . The lower cover 3 has a second cover plate 31 and a second side enclosing plate 32, and the second side enclosing plate 32 is connected with the second cover plate 31 in a sealing way to form a cup shape. The upper cover 2 has a first cover plate 21 and a first side enclosing plate 22, and the first side enclosing plate 22 is connected with the first cover plate 21 in a sealing manner to form a cup shape. The top of the first outer ring 111 of the upper water trap 101 is outwardA flange 114 is provided for location on the floor when the housing 1 is installed. The flange 114 is provided with a groove 1141 for placing the water inlet plate 6. The water inlet plate 6 is provided with a plurality of water inlet holes 61 (see fig. 28), and ground water flows into the upper water storage tank 101 through the water inlet holes 61.
Referring to fig. 1-5, the multifunction bar 4 of the present invention can be suspended from an upper holding tank 101, as follows.
Referring to fig. 1, the upper end of the multifunctional rod 4 is provided with a support frame 42, the support frame 42 can be a straight frame, a herringbone frame, a cross frame or a Chinese character mi frame, and the support frame 42 shown in fig. 1, 4-5, 17 and 20-21 is a cross frame. The support frame 42 is placed on the top surface 1121 (at the upper water outlet 116) of the first inner ring 112 of the upper sump 101, and the multipurpose lever 4 is hung on the upper sump 101 through the support frame 42. The first cover plate 21 of the upper cover 2 is placed on the support frame 42 so that the upper cover 2 is reversely fastened to the upper water outlet 116 of the upper water storage tank 101 through the support frame 42. The supporting frame 42 is disposed at such a height that the first side wall 22 of the upper cover 2 is inserted into the upper water storage tank 101 between the first inner ring 112 and the first outer ring 111, and the first side wall 22 vertically overlaps the first inner ring 112 by a predetermined depth h 1 Thus realizing water sealing and preventing gas from passing through. On the other hand, the support frame 42 is disposed at such a height that a space is provided between the bottom end of the first side wall 22 and the first bottom plate 113 of the upper water reservoir 101, and the water stream a can bypass the space. Since the notches 421 (see fig. 17, 20 and 21) are formed between the rack bars of the support frame 42, when the support frame 42 is placed on the top surface 1121 of the first inner ring 112, each notch 421 of the support frame 42 also provides a gap between the bottom surface of the first cover 21 and the top surface 1121 of the first inner ring 112 of the upper water storage tank 101, through which the water flow a can flow out from the upper water outlet 116 into the lower water storage tank 2 by bypassing the top surface 1121 of the first inner ring 112.
