Description

Technical Field

[0001] The present invention relates to the field of floor drain fittings, and particularly to a floor drain connection pre-embedded part for an integrated waterproof bottom box of ceramic tiles. Background Art

[0002] With the popularization of prefabricated interior decoration, prefabricated integrated bathrooms are increasingly favored by the market. As an integrated waterproof bottom box of ceramic tiles used in prefabricated integrated bathrooms, it has the advantages of controlling the slope of the bathroom floor and facilitating installation.

[0003] Bathroom drainage facilities are essential. Drainage equipment is a very important component used in bathroom decoration. Generally, the drainage is carried out by installing a drainage pipe and a floor drain. Since the floor drain is a fully metal component, it forms an obvious contrast with high-grade decorative stones, which brings certain obstacles to the overall beauty, effective drainage, hair blocking, daily cleaning and maintenance of the shower room. Therefore, hidden floor drains are usually set in prefabricated bathrooms.

[0004] Currently, the general method of installing a hidden floor drain in an integrated waterproof bottom box of ceramic tiles is to install it in a reserved hole. However, the reserved hole is easily damaged during the installation and construction process. In order to facilitate the installation of the hidden floor drain and meet the use environment of prefabricated bathrooms without using mortar and cement for backfilling, those skilled in the art have proposed to realize the connection between the floor drain and the waterproof bottom box through a floor drain pre-embedded part.

[0005] For example, Chinese Patent with the publication number CN212200689U discloses a floor drain pre-embedded part and an overall bathroom side drainage system. The floor drain pre-embedded part includes a floor drain main body, a through pipe and a connection head. The floor drain main body includes a floor drain bottom box. A drainage port is provided on the side wall of the floor drain bottom box. One end of the connection head is communicated with the drainage port, and the other end is communicated with the through pipe. The connection head is fixedly connected to the side wall of the floor drain bottom box. The floor drain pre-embedded part is pressed together with the chassis and is completely buried in the bathroom chassis. During construction, there is no need to install the floor drain pre-embedded part separately, and the drainage pipe on the outer side of the side wall can be directly installed, realizing the connection function between the floor drain and the waterproof bottom box in prefabricated bathrooms.

[0006] However, since this solution is only applicable to floor drains of fixed sizes, and although the connection between the floor drain and the waterproof bottom box is realized through the pre-embedded part, due to the direct connection between the floor drain and the pipeline, phenomena such as back-seepage are likely to occur when the use time is too long or the water flow rate is too slow, and leakage is also likely to occur at the connection between the floor drain and the pipeline after a long time of use. Summary of the Invention

[0007] To solve the above problems, the present invention provides a floor drain connection pre-embedded part for an integrated waterproof bottom box of ceramic tiles to avoid back-seepage and leakage.

[0008] The technical solution of the present invention is a floor drain connection pre-embedded part for an integrated waterproof bottom box of ceramic tiles, which includes a hollow cylindrical support member, a square-ring-shaped connecting member arranged above the cylindrical support member, and a transition member for connecting the hollow cylindrical support member and the square-ring-shaped connecting member. The cylindrical support member includes an annular support plate for connecting the floor drain and an annular docking member for connecting the pipeline. The annular docking member vertically extends downward and is formed on the annular support plate. The transition member vertically extends upward and is formed on the annular support plate. The inner wall of the square-ring-shaped connecting member is sleeved on the middle part of the transition member and is communicated with the drainage pipeline through the annular docking member. The annular support plate is inlaid and supports the floor drain. By using the diameter difference between the inner ring and the outer ring of the annular support plate, the floor drain and the drainage pipeline are not directly connected, forming a buffer space to avoid the problems of floor drain water overflow and back-seepage and water leakage at the pipeline connection. Then, the square-ring-shaped connecting member and the polyurethane waterproof bottom box are adhesively bonded by foaming, and finally the connection between the floor drain and the polyurethane waterproof bottom box is realized.

[0009] Preferably, the transition member includes 4 vertical plates that are sequentially connected end to end, and the vertical plates enclose a rectangular accommodating cavity.

[0010] Preferably, an annular cushion layer is provided in the rectangular accommodating space. The annular cushion layer is arranged above the annular support plate, and the diameter of the annular cushion layer is larger than the inner diameter of the annular support plate.

[0011] Preferably, bumps are provided at the intersections of adjacent vertical plates.

[0012] Preferably, the bump includes an L-shaped cushion block and an L-shaped blocking block stacked above the L-shaped cushion block, and the L-shaped blocking block partially covers the L-shaped cushion block.

[0013] Preferably, a positioning cushion block is arranged above the square-ring-shaped connecting member, and the positioning cushion block is connected to the outer wall of the transition member.

[0014] Preferably, a washer for fastening the floor drain is sleeved on the annular support plate.

[0015] Preferably, the washer is detachably connected to the inner ring of the annular support plate.

[0016] Preferably, the top surface of the transition member is higher than the top surface of the bump.

[0017] Preferably, the square-ring-shaped connecting member protrudes horizontally from the annular support plate.

[0018] The beneficial effects of the present invention are as follows: The embedded part of this solution can be used for the connection of the floor drain and the integrated waterproof bottom box of the ceramic tile in the assembled overall bathroom, without back-seepage or water leakage. The floor drain is detachable and replaceable, suitable for the hidden floor drain integrated with the ceramic tile, and has a variety of applicable floor drain sizes, which can effectively drain water and block hair; the connection between the embedded part and the integrated waterproof bottom box of the ceramic tile is tight and stable.

Detailed Embodiment

[0023] The present invention will be further described in detail below in conjunction with the embodiments.

[0024] In the embodiments of the present invention, the descriptions such as "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0025] At the same time, the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention.

[0026] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", "abutment", "insertion connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] For a clearer understanding of the technical features, objectives, and effects of the present invention, the specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings. However, the embodiments of the present invention are not limited thereto.

[0028] The inventors found that in the prior art, in prefabricated integral bathrooms, since mortar cement is not used for backfilling, the floor drain is often directly connected to the drainage pipe, and then the floor drain and the waterproof bottom box are connected using embedded parts. The reasons for easy leakage or back-seepage are as follows: the connection between the floor drain and the pipe has poor sealing; the aperture of the floor drain is small, and when the drainage speed is too fast, the drainage speed of sewage is limited. In the prior art, the common methods used to solve the above problems are to directly enlarge the aperture of the floor drain or the pipe, or to reinforce the connection between the floor drain and the pipe by means of enhanced adhesion, etc. However, the above methods do not fundamentally solve the problem.

[0029] Therefore, based on the above problems, as Figure 1As shown in the figure, the present application provides a floor drain connection pre-embedded part for an integrated waterproof bottom box of tiles, including a hollow cylindrical support member 1, a square-ring-shaped connecting member 2 arranged above the cylindrical support member, and a transition member 3 for connecting the hollow cylindrical support member 1 and the square-ring-shaped connecting member 2. The cylindrical support member includes an annular support plate 11 for connecting the floor drain and an annular docking member 12 for connecting the pipeline. The annular docking member 12 extends vertically downward and is formed on the annular support plate 11. The transition member 3 extends vertically upward and is formed on the annular support plate 11. The inner wall of the square-ring-shaped connecting member 2 is sleeved on the middle part of the transition member 3. Among them, the annular support plate 11 is parallel to the square-ring-shaped connecting member. The term "pipeline" refers to a drainage pipeline. The term "annular support plate 11" refers to a disc with through holes. The term "square-ring-shaped connecting member 2" refers to a square piece with a rectangular cavity. The diameter of the through hole is smaller than the shorter side length of the rectangular cavity so that the annular support plate 11 has the condition to carry the floor drain, and the diameter of the through hole matches the diameter of the floor drain. The square-ring-shaped connecting member 2 is used to connect with the integrated waterproof bottom box of tiles, and the connection method between the two is polyurethane foam connection. Compared with the connection method only through the transition member 3 and the integrated waterproof bottom box of tiles, the square-ring-shaped connecting member 2 increases the bonding area of the waterproof bottom box pre-embedded part, making the connection more firm and stable. In addition to connecting the hollow cylindrical support member 1 and the square-ring-shaped connecting member 2, the transition member 3 also plays a role in preventing the polyurethane foam from overflowing into the hollow cylindrical support member 1. Based on the above structure, it is communicated with the drainage pipeline through the annular docking member 12, and the communication method can be integrally formed communication or fixed connection communication methods such as bonding and threaded connection. The annular support plate 11 can be inlaid and support the floor drain. By using the diameter difference between the inner ring and the outer ring of the annular support plate 11, the floor drain and the drainage pipeline are not directly connected, forming a buffer space. The connection part between the drainage pipeline and the pre-embedded part does not directly contact the sewage, and at the same time, the problems of floor drain water overflow and back-seepage and pipeline connection leakage are solved.

[0030] In this solution, the transition member 3 includes 4 vertical plates 31 connected end to end in sequence. The vertical plates 31 enclose a rectangular accommodating cavity 32. The rectangular accommodating cavity 32 can be a square accommodating cavity. The side length of the square accommodating cavity is greater than the inner diameter of the annular support plate 11. The end of the vertical plate 31 is connected to the annular support plate 11, and the side part of the vertical plate 31 is connected to the inner wall of the square-ring-shaped connecting member 2. Therefore, the vertical plate 31 realizes the function of connecting the annular support plate 11 and the square-ring-shaped connecting member 2.

[0031] After connecting the floor drain to the embedded part, the inner core of the floor drain passes through the through-hole formed by the annular supporting plate 11 and the end of the floor drain is supported by the platform formed by the annular supporting plate 11. Since the end of the floor drain protrudes from the annular supporting plate 11, a sanitary dead angle will be formed between the floor drain and the annular supporting plate 11. Therefore, an annular cushion layer 4 is provided in the rectangular accommodating space. The annular cushion layer 4 is arranged above the annular supporting plate 11. The diameter of the annular cushion layer 4 is larger than the inner diameter of the annular supporting plate 11. The height of the annular cushion layer 4 is equal to the height of the end of the floor drain to be matched, forming the same horizontal plane, thus solving the problem of the existence of sanitary dead angles.

[0032] In order to install the floor drain cover of the concealed floor drain, bumps 5 are provided at the intersections of adjacent vertical plates 31. Since the vertical plates 31 enclose a rectangle and there are 4 intersections, there are 4 bumps 5. The bumps 5 are used to carry the floor drain cover for drainage and blocking hair.

[0033] In this solution, the bump 5 includes an L-shaped cushion block 51 and an L-shaped blocking block 52 stacked above the L-shaped cushion block 51. The L-shaped blocking block 52 partially covers the L-shaped cushion block 51. In one embodiment, the side surfaces of the L-shaped blocking block 52 and the L-shaped cushion block 51 are in close contact with the corresponding vertical plates 31. The floor drain cover is carried by the L-shaped cushion block 51 and is fitted by 4 L-shaped blocking blocks 52 to achieve the functions of drainage and blocking hair. In another embodiment, there is a certain distance between the side surface of the L-shaped blocking block 52 and the corresponding vertical plate 31, and they are in a separated state. Only the side surface of the L-shaped cushion block 51 is in close contact with the corresponding vertical plate 31. At this time, when the floor drain cover is installed, it is carried by the L-shaped blocking block 52 and can also achieve the functions of drainage and blocking hair. The above two different setting methods can meet the requirements of installing floor drain covers with different thicknesses.

[0034] A positioning cushion block 6 is arranged above the loop-shaped connecting piece 2, and the positioning cushion block 6 is connected to the outer wall of the transition piece 3, that is, the positioning cushion block 6 is arranged at the included angle formed by the loop-shaped connecting piece 2 and the transition piece 3. The function of the positioning cushion block 6 is that when the embedded part and the integrated waterproof bottom box of the ceramic tile are connected by polyurethane foaming, the bonding area is increased, and at the same time, it acts like a reinforcing rib to strengthen the connection strength between the loop-shaped connecting piece 2 and the transition piece 3.

[0035] In order to match floor drains with different inner diameters and achieve seamless connection between the floor drain and the embedded part, a washer 7 for fastening the floor drain is sleeved on the annular supporting plate 11. The washer 7 can be a rubber washer 7, a non-rigid material, and is installed and removed by compression. The washer 7 is detachably connected to the inner ring of the annular supporting plate 11.

[0036] The top surface of the transition piece 3 is higher than the top surface of the bump 5, and the drop is the thickness of the floor drain cover, so that after the floor drain cover is placed on the bump 5, the floor drain cover and the ground are on the same horizontal plane, keeping the ground flat.

[0037] The square-ring-shaped connecting piece 2 protrudes horizontally from the annular supporting plate 11, so that on the basis of the adhesive connection between the square-ring-shaped connecting piece 2 and the integrated waterproof bottom box of the ceramic tile, the plug-in connection function is also provided, making the connection between the two tighter and closer.

[0038] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
