Description

Technical Field

[0001] The invention relates to the technical field of floor drain equipment, and in particular to a drainage floor drain and an installation method thereof. Background Art

[0002] The floor drain is a common drainage component used in the drainage system in the construction field. It is an important interface connecting the drainage pipe system and the indoor floor. The same-floor drainage floor drain is a common indoor drainage system component. It is a drainage device installed on the ground to collect and discharge water to prevent water accumulation indoors. The same-floor drainage floor drain achieves indoor drainage and waterproofing functions by directing the water flow directly into the drainage pipe under the floor drain body. They are usually installed in locations such as bathtubs, shower areas, washbasins, kitchen sinks, and washing machines to collect and discharge water generated in these areas. The same-floor drainage floor drain plays an important role in the indoor drainage system and can ensure indoor hygiene and waterproofing effects.

[0003] Although there are many floor drains for same-floor drainage on the market, such as static water seal horizontal floor drain, self-contained water seal anti-overflow side wall floor drain, self-protective water seal anti-overflow multi-channel floor drain, floating cover anti-overflow multi-channel floor drain, etc., although these products meet the use requirements of floor drains to a certain extent, they still have the following problems: (1) Inconvenient installation and maintenance: Since various existing floor drains cannot be completely disassembled or can only be partially disassembled, when the floor drain itself, especially the pipeline, is blocked during use, it cannot be disassembled for maintenance (unblocking) and reinstalled for use, and can only be dismantled destructively, making installation and maintenance very inconvenient; (2) The sealing of the floor drain is poor. After the floor drain is installed, it will be displaced due to the force, and the joints of the floor drain will become loose, resulting in leakage; (3) At present, most of the same-layer drainage floor drains used in polyurethane waterproof bottom boxes are large-diameter floor drains. The diameter of the upper surface of the floor drain is about 160mm, and it is fixed on the polyurethane bottom box with a 200mm side embedded part. As a result, the finished surface area of ​​the floor drain is about 4 times that of the finished surface of the traditional floor drain. In addition to the complete horizontal floor drain, a hidden floor drain cover made of embedded parts structure and finishing materials is also required, which increases the cost of the floor drain connection.

[0004] The patent with application number 201921688231.0 proposes a same-floor drainage floor drain, including a floor drain box, a waterproof chassis, a flow deflector and a floor drain sealing assembly. The waterproof chassis is arranged above the floor drain box and connected to the water inlet; the flow deflector is arranged inside the floor drain box, the flow deflector includes an upper port and a lower port connected to the upper port, a filter is arranged inside the upper port, and the floor drain sealing assembly is arranged inside the lower port, and the floor drain sealing assembly is used to control the conduction and closing of the flow deflector. Since each component of the drainage floor drain is detachable, the floor drain can be easily installed and repaired; by using adjustable support legs to support the floor drain box, the floor drain can be prevented from being misaligned with the drain pipe during use, thereby causing water leakage; by using a magnetic suspension floor drain sealing assembly, the sealing of the floor drain is improved and the service life of the floor drain is extended. However, since the device is provided with supporting legs under the floor drain box, although it can prevent the floor drain from being misaligned with the drain pipe during use, the existence of the supporting legs will lead to actual installation difficulty and limit the applicable scenarios, and generally, as long as the connection is proper, there will be no problem of misalignment with the drain pipe; in addition, the device uses magnets to improve the sealing of the floor drain, but in actual use, the magnets can easily absorb other iron-containing substances, resulting in the failure to achieve the intended sealing effect. Summary of the invention

[0005] Based on the problems and shortcomings existing in the above-mentioned prior art, the present invention provides a drainage floor drain and an installation method thereof, so as to overcome the problems that the same-layer drainage floor drain used for the polyurethane waterproof bottom box in the prior art is inconvenient to install, maintain and clean, and cannot take into account both sealing and easy disassembly.

[0006] To achieve the above object, the present invention is implemented through the following technical solutions:

[0007] In one aspect, the present invention provides a drainage floor drain, comprising a floor drain body, and an embedded part for fixing the floor drain body in a concealed manner in a facing;

[0008] The embedded part includes an embedded part for embedding between the facing surface and the base layer, and a connecting part for connecting the floor drain body;

[0009] The floor drain body includes, from top to bottom, a threaded barrel adapted to the connection portion, a floor drain cavity threadably connected to the threaded barrel, and a water seal for transferring sewage to the floor drain cavity and preventing odor from returning is arranged inside the threaded barrel;

[0010] Wherein, a sealing clamp is provided at the connection between the connecting portion and the threaded tube and the floor drain cavity, and the sealing clamp includes a first protruding portion and a second protruding portion, and the first protruding portion and the second protruding portion are connected via a receiving portion.

[0011] The polyurethane waterproof bottom box currently used is usually composed of a facing layer and a base layer, and the facing layer and the base layer are filled with polyurethane foam material to bond them into one. The problems existing in the prior art in the same-layer drainage floor drain installed in the polyurethane waterproof bottom box are as follows: (1) The present invention achieves the purpose of stabilizing the embedded part and then fixing the floor drain by embedding the embedded part in the embedded part between the facing and the base layer, and also reduces the exposed area of ​​the floor drain and the finished surface area of ​​the floor drain while stabilizing the drainage floor drain because the embedded part at the edge of the embedded part is embedded between the facing and the base layer, thereby reducing the cost of the floor drain connection while achieving aesthetics; (2) The present invention forms a water seal in the floor drain cavity through the water seal to isolate the waste in the drainage pipe. Gas, has the effect of preventing odor; (3) The present invention provides a sealing clip at the connection between the connection part and the threaded tube and the floor drain cavity. Since the first protrusion in the sealing clip is located between the connection part and the threaded tube, and the second protrusion in the sealing clip is located between the connection part and the floor drain cavity, a good sealing effect can be achieved through the extrusion between the connection part and the threaded tube, and between the connection part and the floor drain cavity. Since the first protrusion and the second protrusion are connected as a whole through the receiving part, compared with the sealing ring used in the existing floor drain, it increases the contact area of ​​the connection, the contact surface is tighter, can provide better sealing performance, reduce the risk of leakage, and effectively prevent liquid or gas from leaking from the joint. At the same time, the installation is more convenient and quick, and easy disassembly is achieved while ensuring a high sealing performance of the connection.

[0012] The various structural parts of the drainage floor drain in the present invention are easy to assemble and can be easily disassembled and cleaned, making subsequent maintenance and cleaning work more convenient; the floor drain is combined with the embedded structure to better adapt to the installation of the floor drain in the polyurethane bottom box, and the finished surface of the floor drain is reduced, which can improve the aesthetics of the bottom box finish.

[0013] Preferably, the embedded part also includes an embedded part body for connecting the embedded portion and the connecting portion, the connecting portion is arranged at the lower end of the embedded part body, and the distance from the upper side surface of the embedded part to the upper end of the embedded part body is equal to the thickness of the facing.

[0014] Preferably, the floor drain body further comprises a floor drain filter screen spliced ​​and connected to the threaded barrel, and the upper side surface of the floor drain filter screen is flush with the upper side surface of the threaded barrel.

[0015] Preferably, the floor drain body further comprises a floor drain cover, and the upper surface of the floor drain cover is flush with the upper side surface of the embedded component body.

[0016] Preferably, the threaded barrel comprises a threaded barrel body, and a clamping portion provided at one end of the threaded barrel body and used for engaging with the connecting portion.

[0017] Preferably, a first clamping protrusion is provided on the inner side of the threaded barrel body, and a second clamping protrusion matched with the first clamping protrusion is provided on the water seal.

[0018] Preferably, the floor drain chamber comprises a floor drain chamber body, and a threaded joint arranged on the floor drain chamber for threaded connection with the threaded barrel body.

[0019] Preferably, the outer surface of the threaded barrel body is provided with external threads, and the inner side of the threaded joint is provided with internal threads that match the external threads on the threaded barrel body.

[0020] By setting the external thread on the outer surface of the threaded barrel body and the internal thread on the inner side of the threaded joint, the threaded connection between the threaded barrel body and the threaded joint can further improve the sewage leakage prevention effect of the connection. That is, after the sewage flows into the drainage floor drain, when the sewage flows through the connection, the sewage will not overflow from the threaded connection. If the internal thread is set on the inner side of the threaded barrel body and the external thread is set on the outer side of the threaded joint, sewage leakage will occur at the threaded connection.

[0021] Preferably, the water inlet diameter of the water seal is larger than the water outlet diameter, and the distance from the lower end of the water seal to the bottom of the floor drain cavity is not greater than the height of the residual water in the floor drain cavity.

[0022] If the water inlet is too small, it may cause blockage and affect the smooth discharge of water. Therefore, the diameter of the water inlet of the water seal should be large enough. In order to form a good liquid seal at the lower end of the water seal, the diameter of the water outlet of the water seal should be smaller than the water inlet, so that the liquid seal formed by the water seal during the drainage process is more stable and dense. This can effectively prevent bad odors from entering the indoor space from the sewer and provide better odor control effects.

[0023] In another aspect, the present invention provides a method for installing the drainage floor drain, comprising the following steps:

[0024] S1: Install the embedded parts, place the embedded parts in the reserved positions in the facing, and place the upper side of the embedded part close to the lower side of the facing, overlap the base layer under the facing, and inject foaming material into the cavity between the facing and the base layer, so as to bond the facing, the embedded part and the base layer into one;

[0025] S2: Install the floor drain cavity, connect and fix the floor drain cavity with the drainage pipe on site, and make the position of the floor drain cavity correspond to the position of the embedded parts;

[0026] S3: Install the sealing clip connector, buckle the sealing clip connector onto the connecting portion, and make the bottom of the sealing clip connector contact with the top surface of the floor drain cavity;

[0027] S4: Install the water seal, place the threaded tube in the embedded part and overlap it, connect the threaded tube with the floor drain cavity thread, and place the water seal in the threaded tube;

[0028] S5: Install the floor drain filter and overlap the floor drain filter on the upper end of the threaded tube;

[0029] S6: Install the floor drain cover and close the floor drain cover on the top of the embedded part to complete the installation of the drainage floor drain.

[0030] The present invention has the following beneficial effects:

[0031] (1) The various structural parts of the drainage floor drain in the present invention are easy to assemble and can be easily disassembled and cleaned, making subsequent maintenance and cleaning work more convenient;

[0032] (2) The present invention combines the floor drain with the embedded structure to better adapt to the installation of the floor drain in the polyurethane bottom box, and reduces the finished surface of the floor drain, which can improve the aesthetics of the bottom box surface;

[0033] (3) The present invention provides a sealing clip at the connection between the connection part and the threaded tube and the floor drain cavity. Since the first protrusion and the second protrusion are connected as a whole through the receiving part, compared with the sealing ring used in the existing floor drain, the contact area of ​​the connection is increased, the contact surface is tighter, and better sealing performance can be provided, the risk of leakage is reduced, and liquid or gas can be effectively prevented from leaking from the joint. At the same time, the installation is more convenient and quick, and the high sealing performance of the connection is ensured while achieving easy disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0047] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments of the specification. Those of ordinary skill in the art will be able to implement the present invention based on these descriptions. In addition, the embodiments of the present invention involved in the following description are generally only embodiments of a part of the present invention, rather than all embodiments. Therefore, based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative work should fall within the scope of protection of the present invention.

[0048] The drawings of this specification are schematic diagrams, which assist in explaining the concept of the present invention and schematically show the shapes of various parts and their mutual relationships. Please note that in order to clearly show the structures of various components of the embodiments of the present invention, the drawings are not drawn to the same scale, and the same reference numerals are used to represent the same parts.

[0049] like Figures 1 to 11 As shown, the drainage floor drain in this embodiment includes a floor drain body 1, and an embedded part 2 for fixing the floor drain body 1 in a concealed manner in the finishing surface 3; the embedded part 2 includes an embedded part 21 for being embedded between the finishing surface 3 and the base layer 4, and a connecting part 22 for connecting the floor drain body 1; the floor drain body 1 includes, from top to bottom, a threaded barrel 11 adapted to the connecting part 22, a floor drain cavity 12 threadedly connected to the threaded barrel 11, and a water seal 13 for transferring sewage to the floor drain cavity 12 and preventing odor from returning is provided on the inner side of the threaded barrel 11; wherein, a sealing clip 14 is provided at the connection between the connecting part 22 and the threaded barrel 11 and the floor drain cavity 12, and the sealing clip 14 includes a first protrusion 141 and a second protrusion 142, and the first protrusion 141 and the second protrusion 142 are connected by a receiving part 143.

[0050] By embedding the embedded part 21 in the embedded part 2 between the facing 3 and the base layer 4, the embedded part 21, the facing 3 and the base layer 4 are bonded as a whole, so that the embedded part 2 is stabilized, and the purpose of fixing the floor drain is achieved. In addition, because the embedded part 21 at the edge of the embedded part 2 is embedded between the facing 3 and the base layer 4, the exposed area of ​​the floor drain can be reduced while stabilizing the drainage floor drain, and the finished surface area of ​​the floor drain can be reduced, so that the cost of the floor drain connection can be reduced while achieving aesthetics. The floor drain is combined with the embedded structure to better adapt to the installation of the floor drain in the polyurethane bottom box, and the finished surface of the floor drain is reduced, which can improve the aesthetics of the bottom box facing 3.

[0051] By arranging the water seal 13 in the threaded tube 11 of the floor drain, a water seal can be formed in the floor drain cavity 12 through the water seal 13 to isolate the waste gas in the drainage pipe and prevent odor.

[0052] By setting a sealing clamp 14 at the connection between the connection part 22 and the threaded barrel 11 and the floor drain cavity 12, since the first protrusion 141 in the sealing clamp 14 is located between the connection part 22 and the threaded barrel 11, and the second protrusion 142 in the sealing clamp 14 is located between the connection part 22 and the floor drain cavity 12, a good sealing effect can be achieved through the extrusion between the connection part 22 and the threaded barrel 11, and the extrusion between the connection part 22 and the floor drain cavity 12. Since the first protrusion 141 and the second protrusion 142 are connected as a whole through the receiving part 143, compared with the sealing ring used in the existing floor drain, it increases the contact area of ​​the connection, the contact surface is tighter, can provide better sealing performance, reduce the risk of leakage, effectively prevent liquid or gas from leaking from the joint, and is more convenient and quick to install.

[0053] The embedded part 2 also includes an embedded part body 23 for connecting the embedded part 21 and the connecting part 22. The connecting part 22 is arranged at the lower end of the embedded part body 23. The distance from the upper side of the embedded part 21 to the upper end of the embedded part body 23 is equal to the thickness of the facing 3. The distance from the upper side of the embedded part 21 to the upper end of the embedded part body 23 is designed to be the thickness of the facing 3, so that the floor drain after installation can be flatly embedded in the facing 3, thereby improving the aesthetics of the polyurethane bottom box facing 3.

[0054] The floor drain body 1 also includes a floor drain filter 15 spliced ​​and connected to the threaded barrel 11, and the upper side of the floor drain filter 15 is flush with the upper side of the threaded barrel 11. A first splicing protrusion 115 is provided on the inner side of the threaded barrel 11, and a first splicing groove 151 adapted to the first splicing protrusion 115 is provided on the outer side of the floor drain filter 15. The first splicing groove 151 on the outer side of the floor drain filter 15 is aligned and overlapped to the position of the first splicing protrusion 115 on the inner side of the threaded barrel 11, thereby realizing the connection between the floor drain filter 15 and the threaded barrel 11.

[0055] The floor drain body 1 also includes a floor drain cover 16, the upper surface of which is flush with the upper side surface of the embedded component body 23. The floor drain cover 16 is provided with a second splicing protrusion 161, and the upper inner wall of the embedded component body 23 is correspondingly provided with a third splicing groove 24 adapted to the second splicing protrusion 161, and a third clamping protrusion 25. After the second splicing protrusion 161 on the floor drain cover 16 is aligned with the third splicing groove 24 and overlapped on the third clamping protrusion 25, the floor drain cover 16 is rotated to stagger the positions of the second splicing protrusion 161 and the third splicing groove 24, so that the floor drain cover 16 and the embedded component 2 are mutually clamped and fixed.

[0056] The threaded barrel 11 includes a threaded barrel body 111 and a clamping portion 112 disposed at one end of the threaded barrel body 111 for mating with the connecting portion 22. The inner side of the threaded barrel body 111 is provided with first clamping protrusions 113 distributed along the circumference of the threaded barrel body 111, and the water seal 13 is provided with second clamping protrusions 131 matched with the first clamping protrusions 113. In order to further limit the position of the water seal 13 in the floor drain, a limiting protrusion 114 is further provided on the inner side of the threaded barrel 11, and the limiting protrusion 114 is located between the first splicing protrusion 115 and the first clamping protrusion 113. The second clamping protrusion 131 of the water seal 13 is provided with a second splicing groove 132 corresponding to the first splicing protrusion 115 and the limiting protrusion 114. During installation, when the second splicing groove 132 on the water seal 13 passes through the first splicing protrusion 115 and the limiting protrusion 114 in sequence and is overlapped on the first clamping protrusion 113, the water seal 13 is rotated so that the second splicing groove 132 in the second clamping protrusion 131 is staggered with the limiting protrusion 114, so that the water seal 13 is firmly clamped in the threaded barrel 11.

[0057] The floor drain chamber 12 includes a floor drain chamber body 121, and a threaded joint 122 arranged on the floor drain chamber 12 for threaded connection with the threaded barrel body 111. The outer surface of the threaded barrel body 111 is provided with an external thread, and the inner side of the threaded joint 122 is provided with an internal thread that matches the external thread on the threaded barrel body 111. By providing the external thread on the outer surface of the threaded barrel body 111 and the internal thread on the inner side of the threaded joint 122, the threaded connection between the threaded barrel body 111 and the threaded joint 122 can further improve the anti-sewage leakage effect of the connection, that is, after the sewage flows into the drainage floor drain, when the sewage flows through the connection, the sewage will not overflow from the threaded connection. The upper end of the threaded joint 122 is also provided with an annular belt 123. When the threaded barrel body 111 and the threaded joint 122 are threadedly connected, the annular belt 123 at the upper end of the threaded joint 122 will squeeze the sealing clamp 14, which can further improve the sealing effect of the connection.

[0058] The water inlet diameter of the water seal 13 is larger than the water outlet diameter, and the distance from the lower end of the water seal 13 to the bottom of the floor drain cavity 12 is not greater than the height of the residual water in the floor drain cavity 12. If the water inlet is too small, it may cause blockage problems and affect the smooth discharge of water flow, so the caliber of the water inlet of the water seal 13 should be large enough. In order to form a good liquid seal at the lower end of the water seal 13, the caliber of the water outlet of the water seal 13 should be smaller than the water inlet, so that the liquid seal formed by the water seal 13 during the drainage process is more stable and dense. This can effectively prevent foul odors from entering the indoor space from the sewer, providing a better odor control effect.
