Description

Technical Field

[0001] The utility model belongs to the drainage field and relates to an embedded floor drain. Background Art

[0002] The embedded floor drain is different from the traditional floor drain and has the advantages of being more concealed and more beautiful. For example, the utility model patent with the application number 2021211103331 and the name of "utility model with an extended floor drain" applied by the applicant on May 23, 2021, discloses a floor drain with an extension, which includes a housing with a cavity inside and an opening at the top, a sewage outlet at the bottom of the housing, a filter panel on the housing, and a filter structure inside the housing. The filter structure includes a number of sewage discharge holes that communicate with the sewage outlet. There is an outwardly extending extension at the side of the top of the housing, and the floor covering material is laid above the extension and at least one edge of the floor covering material is flush with the inner edge of the extension. The housing is a cuboid as a whole, and extensions extend outward from all four sides of the top of the housing, and the four extensions form a square shape as a whole. Combining with the accompanying drawings of its specification, tiles are pasted on the extension. Since there is no positioning structure on the above floor drain, a locator is needed during specific installation. The locator is installed on the floor drain, and then the tiles can be pasted. After the tiles are pasted, the locator is removed. The operation is rather troublesome, and the installation accuracy of the locator needs to be considered. If the locator is not installed in place, it will lead to problems with the tiling accuracy. Generally speaking, there are many drawbacks in the current method.

[0003] To solve the above problems, this application is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide an embedded floor drain for the above problems existing in the prior art. This floor drain has the advantages of convenient positioning and accurate laying of auxiliary materials, and solves the problems of troublesome positioning and many uncertain factors of the existing embedded floor drains.

[0005] The purpose of the utility model can be achieved by the following technical solutions: The embedded floor drain includes a housing and a drain core. The top of the housing is an opening, and the bottom has a sewage outlet. The drain core is installed at the sewage outlet. The characteristic is that both opposite sides of the top of the housing have outwardly extending fitting parts, the top surface of the fitting part is a fitting surface, both the other two opposite sides of the top of the housing have upwardly extending positioning platforms, the surface of the positioning platform corresponding to the fitting surface is a positioning surface, and the top surface of the positioning platform is higher than the fitting surface.

[0006] The bonding surface of the bonding part is used to bond the ceramic tiles. There are two positioning surfaces on each positioning platform, corresponding to the bonding surfaces on one side respectively. The functions of the positioning platform are at least three. First, it forms a positioning surface for positioning the laying of ceramic tiles. Second, it forms a height to fill the height defects on both sides caused by laying ceramic tiles in the shell. Third, it increases the filtering depth of the shell and improves the filtering efficiency. Specifically, first, after the shell is buried in the preset position, the ceramic tile can be pushed against the corresponding positioning surface along the bonding part, and the two sides of the ceramic tile can be aligned through the length of the bonding part. The existence of the positioning platform can realize the rapid covering of the ceramic tile, which is convenient to operate and does not require the installation of a positioner. Second, in the technical solution in the background art, since its outer extensions are on all four sides, ceramic tiles need to be laid on all four outer extensions, which also involves the positioning problem and is very inconvenient to operate. In this solution, the bonding part is only on both sides, and the other two sides are protruding positioning platforms. After the ceramic tile at the bonding part is bonded, it is flush with the top surface of the positioning platform. When pasted against the wall, ceramic tiles do not need to be pasted on the two sides with positioning platforms, and the height here can be compensated by the positioning platforms. The area is small and is easily acceptable to consumers. When not against the wall, when laying ceramic tiles in the area outside the positioning platform, only the outer side surface of the positioning platform needs to be used for positioning and pasting, and the positioning function is realized again. Third, since the ceramic tile is flush with the positioning platform after laying, the filtering depth of the shell is increased indirectly, realizing the rapid drainage of sewage and improving the sewage discharge efficiency. The positioning platform of this pre-buried floor drain is ingeniously designed and has multiple advantages.

[0007] In the above-mentioned pre-buried floor drain, both the bonding part and the positioning platform are cuboids, and both the bonding surface and the positioning surface are rectangles.

[0008] This floor drain is a strip-shaped floor drain.

[0009] In the above-mentioned pre-buried floor drain, it further includes a panel assembly. The panel assembly includes a filter strip and a filter cover. The filter cover is a hollow structure and is located on the inner bottom wall of the shell and communicates with the sewage discharge port. The filter strip is placed in the shell and divides the inner cavity of the shell. The top of the filter strip is flush with the top surface of the positioning platform.

[0010] The traditional filtering mode relies on the panel. Filter holes are set on the panel, and filtering is realized through the filter holes. The technical solution in the background art is like this. The background solution has the following problems. One is that the filter holes are located in the relatively top area of the shell, the filtering depth is small, the filtering efficiency is low, and the space at the bottom of the shell is wasted seriously. In this technical solution, the separating function and the filtering function of the panel are separated into two parts, namely the filter strip and the filter cover. The filter strip plays a role in separating the inner cavity of the shell to prevent the gap from being too large, and the filter cover plays a filtering role. The filter cover is located on the inner bottom wall of the shell, maximizing the filtering space. And the split design reduces the requirements for the filter strip, making it only need to bear the separating function.

[0011] In the above-mentioned embedded floor drain, the filter cover is flared from top to bottom, and there are several sewage discharge holes on the outer wall of the filter cover.

[0012] The flared shape makes the height of the filter cover higher, thereby reducing the width of the filter strip. Secondly, the outer wall of the filter cover is in an inclined shape. A straight barrel structure is likely to cause sewage to splash out during sewage discharge, and the inclined structure can achieve buffering.

[0013] In the above-mentioned embedded floor drain, the length of the filter cover is less than the length of the filter strip.

[0014] The length of the filter cover can deliberately be one-half, one-fourth or even less of the length of the filter strip. Reducing the size of the filter cover can reduce costs.

[0015] In the above-mentioned embedded floor drain, there is a positioning port on the inner bottom wall of the housing, and the bottom of the filter cover is placed in the positioning port.

[0016] The shape of the positioning port is the same as the shape of the bottom of the filter cover, and is used for positioning the filter cover.

[0017] In the above-mentioned embedded floor drain, the top of the filter cover has a positioning groove, and the bottom of the filter strip is placed in the positioning groove.

[0018] Both ends of the positioning groove are open, and the bottom of the filter strip is positioned through the positioning groove.

[0019] In the above-mentioned embedded floor drain, a through top row hole is opened at the bottom of the positioning groove.

[0020] The top row hole is used for sewage discharge to prevent sewage from accumulating at the positioning groove.

[0021] In the above-mentioned embedded floor drain, on both sides of the housing where the positioning platform is located, there are also limiting steps. Limiting grooves are opened on the limiting steps, and both ends of the filter strip are placed in the limiting grooves.

[0022] The limiting steps are used for positioning both ends of the filter strip to prevent shaking.

[0023] In the above-mentioned embedded floor drain, the filter strip is a cuboid.

[0024] In this solution, the filter strip is a simple cuboid structure and only needs to play a role in partitioning.

[0025] Compared with the prior art, the present embedded floor drain has the following advantages:

[0026] 1. The present embedded floor drain realizes the rapid laying of paving materials through the mutual cooperation of the fitting part and the positioning platform, without the need to install a positioner, and the positioning platform also has a positioning effect on the laying of tiles outside the positioning platform.

[0027] 2. This embedded floor drain divides the filter panel into filter strips and a filter cover. The two separately perform the functions of division and filtration, and through the division structure, their shape structures and installation positions are more flexible.

[0051] like Figures 1 to 7 As shown, the embedded floor drain comprises a shell 1 and a drain core 1a. The top of the shell 1 is open and the bottom has a drain outlet 1b. The drain core 1a is installed at the drain outlet 1b. The two opposite sides of the top of the shell 1 have a fitting portion 1c extending outward. The top surface of the fitting portion 1c is a fitting surface 1c1. The other two opposite sides of the top of the shell 1 have a positioning platform 1d extending upward. The surface corresponding to the fitting surface 1c1 on the positioning platform 1d is a positioning surface 1d1. The top surface of the positioning platform 1d is higher than the fitting surface 1c1. The fitting surface 1c1 of the fitting portion 1c is used to fit tiles. There are two positioning surfaces 1d1 on each positioning platform 1d, which correspond to the fitting surface 1c1 on one side. The positioning platform 1d has at least three functions. One is to form the positioning surface 1d1 for positioning the laying of tiles. The second is to form a height to fill the height defects on both sides of the shell 1 caused by laying tiles. The third is to increase the filtering depth of the shell 1 and improve the filtering efficiency. Specifically, firstly, after the shell 1 is buried in the preset position, the tile can be placed on the corresponding positioning surface 1d1 along the fitting portion 1c, and the two sides of the tile can be aligned by the length of the fitting portion 1c. The existence of the positioning platform 1d can realize the rapid laying of the tile, which is convenient to operate and does not require the installation of a positioner; secondly, the technical solution in the background technology has an extension on all sides, so tiles need to be laid on all the extensions on all sides, which also involves positioning problems and is very inconvenient to operate. In this solution, the fitting portion 1c is only on both sides, and the other two sides are convex The positioning platform 1d is exposed, and the tiles at the fitting part 1c are flush with the top surface of the positioning platform 1d after being fitted. When pasting against the wall, there is no need to paste tiles on both sides of the positioning platform 1d. The positioning platform 1d can make up for the height here, and the area is small and easy for consumers to accept. When not against the wall, when pasting tiles in the area outside the positioning platform 1d, it only needs to be positioned and pasted through the outer side of the positioning platform 1d, and the positioning function is realized again; thirdly, because the tiles are flush with the positioning platform 1d after being laid, the filtering depth of the shell 1 is increased in disguise, and the sewage is quickly discharged, which improves the sewage discharge efficiency. The positioning platform 1d of this embedded floor drain is cleverly designed and has multiple advantages.

[0052] The fitting part 1c and the positioning table 1d are both cuboids, and the fitting surface 1c1 and the positioning surface 1d1 are both rectangles. The local drain is a strip-shaped floor drain. It further includes a panel assembly, which includes a filter strip 2 and a filter cover 3. The filter cover 3 is a hollow structure and is located on the inner bottom wall of the housing 1 and communicates with the sewage outlet 1b. The filter strip 2 is placed inside the housing 1 and divides the inner cavity of the housing 1. The top of the filter strip 2 is flush with the top surface of the positioning table 1d. The traditional filtering mode relies on the panel, and filtering holes are set on the panel, and filtering is achieved through the filtering holes. The technical solution in the background art is like this. There are the following several problems with the background solution. One is that the filtering holes are located in the relatively top area of the housing 1, the filtering depth is small, and the filtering efficiency is low. The space at the bottom of the housing 1 is seriously wasted. In this technical solution, the separating function and the filtering function of the panel are separated into two parts, namely the filter strip 2 and the filter cover 3. The filter strip 2 plays a role in dividing the inner cavity of the housing 1 to prevent the gap from being too large, and the filter cover 3 plays a filtering role. The filter cover 3 is located on the inner bottom wall of the housing 1, maximizing the filtering space. And the split design reduces the requirements for the filter strip 2, making it only need to bear the dividing function. The filter cover 3 is flared from top to bottom, and there are several sewage discharge holes 3a on the outer wall of the filter cover 3. The flared shape makes the height of the filter cover 3 higher, thereby reducing the width of the filter strip 2. Second, the outer wall of the filter cover 3 is in an inclined shape. A straight cylinder structure is likely to cause sewage to splash out when discharging sewage, and a buffer can be achieved through the inclined structure. The length of the filter cover 3 is less than the length of the filter strip 2.

[0053] The length of the filter cover 3 is deliberately one-half, one-fourth or even less of the length of the filter strip 2. Reducing the size of the filter cover 3 can reduce costs. There is a positioning opening 1e on the inner bottom wall of the housing 1, and the bottom of the filter cover 3 is placed in the positioning opening 1e. The shape of the positioning opening 1e is the same as the shape of the bottom of the filter cover 3, which is used for positioning the filter cover 3. The top of the filter cover 3 has a positioning groove 3b, and the bottom of the filter strip 2 is placed in the positioning groove 3b. Both ends of the positioning groove 3b are open, and the bottom of the filter strip 2 is positioned through the positioning groove 3b. A through top row hole 3b1 is opened at the bottom of the positioning groove 3b. The top row hole 3b1 is used for sewage discharge to prevent sewage from accumulating at the positioning groove 3b. There are also limit steps 1f on both sides of the housing 1 where the positioning table 1d is located, and limit grooves 1f1 are opened on the limit steps 1f. Both ends of the filter strip 2 are placed in the limit grooves 1f1. The limit steps 1f are used for positioning both ends of the filter strip 2 to prevent shaking. The filter strip 2 is a cuboid. In this solution, the filter strip 2 is a simple cuboid structure and only needs to play a dividing role.
