Description

Technical Field

[0001] This invention relates to the field of floor drain technology, specifically to a three-dimensional box-type floor drain. Background Art

[0002] Existing floor drain inlet covers have a flat structure with a grille to trap long, thin debris such as hair or fibers, preventing them from clogging the drain or interfering with the odor-preventing valve. However, this type of flat-cover (flat-structure inlet cover) floor drain has some drawbacks. When wastewater mixes with foam, the foam flows with the water to the inlet cover and forms a water film under the grille's obstruction, causing blockage of the inlet. While the design of this type of drain intended to remove debris blocked by the inlet cover, foam or hair clogging usually occurs during showering, making timely cleaning inconvenient and affecting subsequent drainage speed, resulting in a poor user experience. Summary of the Invention

[0003] The purpose of this invention is to provide a three-dimensional box-type floor drain to solve the problem of foam clogging the inlet and affecting the drainage of the floor drain.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: a three-dimensional box-type floor drain, comprising a body and a cover plate assembly, the cover plate assembly covering the top of the body, the cover plate assembly including a water inlet recess, the water inlet recess being lower than the top edge of the outer frame of the body, thereby forming a sunken water inlet structure; the bottom surface of the water inlet recess is provided with a plurality of spaced-apart lower water inlets, and the side wall of the water inlet recess is provided with a plurality of spaced-apart side water inlets.

[0005] In one embodiment, the bottom surface and / or sidewall of the water inlet recess is a grid structure, the gaps in the grids on the bottom surface of the water inlet recess form the lower water inlet, and the gaps in the grids on the sidewall of the water inlet recess form the side water inlet.

[0006] In one embodiment, the body is provided with a support portion for supporting the cover plate assembly. One side of the support portion is provided with the water inlet recess, and the other side of the support portion is provided with a water outlet for connecting to a drain pipe, thereby forming a drainage channel between the water inlet recess and the water outlet. The drainage channel is provided with a one-way valve, which is used to cut off the fluid communication between the water inlet recess and the water outlet, thereby forming a first odor-proof structure.

[0007] In one embodiment, the support portion is provided with a first drain outlet for connecting the water inlet recess and the water outlet, and the one-way valve is provided on one side of the support portion, and the one-way valve is used to cover the first drain outlet to close the first drain outlet, thereby cutting off the fluid communication between the water inlet recess and the water outlet.

[0008] In one embodiment, the support portion is provided with a first drain outlet, and the support portion is provided with a water-blocking portion on the side near the water inlet recess. The water-blocking portion is provided with a second drain outlet. The water inlet recess is connected to the water outlet through the first drain outlet and the second drain outlet. The one-way valve is provided on one side of the second drain outlet, and the one-way valve is used to cover the second drain outlet to close the second drain outlet, thereby cutting off the fluid communication between the water inlet recess and the water outlet.

[0009] In one embodiment, the water-blocking part includes a water-blocking cover disposed above the one-way valve. The one-way valve includes a rotating shaft. The lower side of the rotating shaft is placed on the arc-shaped groove of the support part, and the upper side of the rotating shaft is pressed against by the connecting part or the water-blocking cover, thereby forming a limit on the rotating shaft.

[0010] In one embodiment, the cover assembly is disposed on the support and covers the water outlet, and the cover assembly cooperates with the support to form a second odor-proof structure.

[0011] In one embodiment, the cover assembly includes a water inlet, the water inlet having a connecting portion, the water inlet recess surrounding the connecting portion, and the connecting portion having a connecting hole for installing a drain pipe.

[0012] In one embodiment, the cover assembly further includes a decorative cover disposed above the water inlet, the decorative cover being disposed above the connection hole, and the water inlet and the decorative cover forming a third odor-proof structure.

[0013] In one embodiment, the bottom of the cover plate assembly is provided with a mating post; the bottom end of the body is provided with a mating flange, the inner wall of the mating flange is used to connect and mate with a small-diameter sewer pipe, and the outer wall of the mating flange is used to connect and mate with a large-diameter sewer pipe.

[0014] The beneficial effects of this invention are:

[0015] 1. The present invention forms a sunken water inlet structure by means of a water inlet recess lower than the top edge of the outer frame of the main body. When sewage carrying a large amount of foam flows into the water inlet recess, since the density of foam is less than that of water, the foam accumulated in the water inlet recess can be lifted by the water and leave the water inlet, so that the sewage can flow smoothly into the water inlet and flow downward. If there are long strip-shaped debris such as hair or fibers in the sewage, the debris will accumulate at the lower water inlet under the action of water flow and gravity, and the sewage will flow in from the side water inlet to achieve smooth drainage.

[0016] 2. The first and second odor-proof structures work together to form a double odor-proof structure, which can prevent the odor from overflowing from the sewer and make the odor prevention more reliable.

[0017] 3. The connection holes provided at the connection point can be used to install drain pipes for the drainage of washing devices such as washing machines and sinks, thereby combining floor drainage with water pipe drainage.

[0018] 4. The third odor-proof structure can close the connection hole when no water pipe is installed, preventing odor and germs from overflowing from the connection hole and ensuring the spread of odor and germs in the ground drainage. Attached Figure Description

Detailed Implementation

[0030] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention, primarily used to illustrate the embodiments and to explain the operating principles of the embodiments in conjunction with the relevant descriptions in the specification. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0031] Example 1

[0032] See Figures 1 to 3 As shown, this invention discloses a three-dimensional box-type floor drain, including a body 1 and a cover assembly 2. The cover assembly 2 covers the top of the body 1 and includes a water inlet recess 21, which is lower than the top of the body 1, thus forming a sunken water inlet structure. The bottom surface of the water inlet recess 21 has multiple spaced-apart lower water inlets 211, and the side walls of the water inlet recess 21 have multiple spaced-apart side water inlets 212. The multiple spaced-apart lower water inlets 211 and side water inlets 212 on the bottom surface and side walls of the water inlet recess 21 respectively enable the structure between adjacent lower water inlets 211 to intercept long, thin debris such as hair or fibers. When the lower water inlet 211 is blocked by the accumulation of long, thin debris, water can enter through the side water inlets 212, which are higher than the lower water inlets 211, preventing blockage and drainage. In addition, when the sewage discharged from the drain contains a large amount of foam, the less dense foam will float to the surface. The foam has a certain degree of viscosity, and the sidewall of the inlet recess 21 can adhere to a certain amount of foam, so that more foam is left in the inlet recess 21, which helps the sewage to drain into the sewer quickly. The foam adhering to the inlet recess 21 can gradually dissipate.

[0033] The biggest difference between the cover plate assembly 2 of the present invention and the planar structure in the prior art is that the cover plate assembly 2 is a three-dimensional structure. The design of the water inlet recess 21 being lower than the top of the main body 1 creates a sunken water inlet. The water inlet recess is provided with a lower water inlet 211 and a side water inlet 212, thus forming a three-dimensional water inlet combining lower and side water inlets. This overcomes the problem that the water inlet of the existing planar water inlet structure is easily blocked by thin debris and foam, improving the water inlet speed of the floor drain and accelerating ground drainage.

[0034] Furthermore, the bottom surface and sidewalls of the water inlet recess 21 are both grid structures. The gaps in the grids on the bottom surface of the water inlet recess 21 form a lower water inlet 211, and the gaps in the grids on the sidewalls of the water inlet recess 21 form a side water inlet 212. The grid structure can effectively divert the water flow into the water inlet recess 21 in the width direction, thereby effectively intercepting slender debris mixed in the water flow. In other embodiments, only the bottom surface or sidewalls of the water inlet recess 21 may be configured as grid structures.

[0035] See Figures 3 to 6 As shown, in this example, the cover assembly 2 includes a water inlet 201, which has a connecting portion 22, and a water inlet recess 21 surrounds the connecting portion 22. The body 1 has a support portion 11 for supporting the cover assembly 2. One side of the support portion 11 has a water inlet recess 21, and the other side of the support portion 11 has a water outlet 12 for connecting to a drain pipe, thereby forming a drainage channel between the water inlet recess 21 and the water outlet 12. The drainage channel is equipped with a one-way valve 3, which is used to cut off the fluid communication between the water inlet recess 21 and the water outlet 12, thereby forming a first odor-proof structure. When the one-way valve 3 is open, the water in the water inlet recess 21 flows along... Figure 3 and Figure 4 The water flows in the direction indicated by the arrow to outlet 12, and is then discharged into the building's sewer system.

[0036] The connecting part 22 of the water inlet 201 has a circular structure, and the supporting part 11 also has a circular structure. The water outlet 12 is located inside and below the supporting part 11, and the water inlet recess 21 is located outside the supporting part 11. The supporting part 11 has a first drain outlet 111, and a water-blocking part 13 is provided on the side of the supporting part 11 near the water inlet recess 21, and the water-blocking part 13 is located below the water inlet recess 21. The water-blocking part 13 has a second drain outlet 131, and the water inlet recess 21 is connected to the water outlet 12 through the first drain outlet 111 and the second drain outlet 131. A one-way valve 3 is provided on one side of the second drain outlet 131, and the one-way valve 3 is used to cover the second drain outlet 131 to close the second drain outlet 131, thereby cutting off the fluid communication between the water inlet recess 21 and the water outlet 12.

[0037] More specifically, the connecting portion 22 of the water inlet 201 is a circular flat plate structure, and the sidewall of the water inlet recess 21 extends downward from the periphery of the connecting portion 22; therefore, the sidewall of the water inlet recess 21 is also a circular structure. The support portion 11 is located inside the sidewall of the water inlet recess 21, supporting the water inlet 201 from below. There is a certain gap between the support portion 11 and the sidewall of the water inlet recess 21 to allow sewage to drain through the gap. The support portion 11 of the body 1 has a bottom wall on its outer side, and the bottom wall is lower than the water inlet recess 21, so that sewage flows downward through the water inlet recess 21 to the first drain outlet 111.

[0038] The support portion 11 is located inside the side wall of the water inlet recess 21, and the support portion 11 has a cylindrical structure. Therefore, the one-way valve 3 is located at the second drain outlet 131, so that the movement of the one-way valve 3 opens or closes the second drain outlet 131, thereby connecting or disconnecting the fluid communication between the water inlet recess 21 and the water outlet 12. In other embodiments, the one-way valve 3 may also be located at the first drain outlet 111, and the fluid communication between the water inlet recess 21 and the water outlet 12 is disconnected by closing the first drain outlet 111.

[0039] Two baffles 112 are provided on the outer side of the support part 11. Each baffle 112 is provided with a second drain outlet 131. Both baffles 112 are flat structures, which are easier to cooperate with the one-way valve 3 to form a first odor-proof structure compared to the arc-shaped side wall of the support part. A baffle cover 101 is also provided above the two baffles 112. The two baffles 112 and the baffle cover 101 cooperate to form a water-blocking part 13. The baffle cover 101 is set at a position lower than the water inlet recess 21, so that the sewage from the water inlet recess 21 flows to both sides of the baffle cover 101 and then enters the internal space of the water-blocking part 13 through the second drain outlet 131. The first drain outlet 111 on the support part 11 is set corresponding to the water-blocking part 13. Therefore, after the sewage enters the water inlet recess 21, it passes through the second drain outlet 131 and the first drain outlet 111 in sequence before being discharged from the outlet 12 into the sewer.

[0040] The one-way valve 3 includes a rotating shaft portion 31 and a valve body portion 32. The lower side of the rotating shaft portion 31 is placed on the arc-shaped groove 1121 of the support portion 11. Specifically, the arc-shaped groove 1121 is set on the top of the baffle plate 112, thus the arc-shaped groove 1121 serves to support the rotating shaft portion 31 of the one-way valve 3. The upper side of the rotating shaft portion 31 is pressed against by the baffle cover 101. In order to facilitate the rotation of the one-way valve 3, the lower side of the baffle cover 101 is also provided with an arc-shaped groove. Thus, the baffle plate 112 of the support portion 11 and the baffle cover 101 cooperate to form a limit on the rotating shaft portion 31, so as to prevent the one-way valve 3 from disengaging from the baffle plate 112 during rotation. The structure of the water baffle cover 101 and the water baffle plate 112 in conjunction with the limiting pivot part 31 facilitates the installation of the one-way valve 3. During installation, the one-way valve is placed in the arc groove 1121 on the water baffle plate 112 and then the water baffle cover 101 is placed on top of the water baffle plate 112. On the other hand, it also facilitates the disassembly and maintenance of the one-way valve 3. The one-way valve 3 can be disassembled and maintained simply by opening the water baffle cover 101.

[0041] The valve body 32 of the one-way valve 3 is used to close or open the second drain port 131, and the valve body 32 is provided with a thickened structure 320 so that the one-way valve 3 can automatically close the second drain port 131 under the action of gravity. When there is water flow in the drainage channel, the water flow can overcome the gravity of the one-way valve 3 and push the one-way valve 3 open, thereby opening the second drain port 131.

[0042] The one-way valve 3 serves as an odor-proof function, preventing sewer odors from flowing back into the space above the floor drain through the outlet 12, drainage channel, and inlet groove 21. Furthermore, the inner wall of the main body 1 and the outer wall of the support 11 are respectively provided with mating parts 113. The mating parts 113 are positioned between the two baffles 112 and abut against the lower surface of the baffle cover 101, thereby forming an odor-proof, airtight structure between the baffle cover 101 and the main body 1 and its support 11.

[0043] See Figure 3As shown, the cover assembly 2 is mounted on the support portion 11 and covers the outlet 12 radially. More specifically, the connecting portion 22 of the cover assembly 2 covers the outlet 12. The inlet component 201 of the cover assembly 2 cooperates with the support portion 11 to form a second odor-proof structure. This prevents sewer odors from overflowing directly upwards from the outlet 12 to the outside of the drain. The second odor-proof structure is formed by the top surface of the support portion 11 abutting against the lower side of the inlet component 201.

[0044] See Figure 7 As shown, in one embodiment, the connecting part 22 is also provided with a connecting hole 221 for installing a drain pipe. Here, the drain pipe refers to the drain pipe of a sink, washing machine, or other washing facilities. The drain pipe can be inserted into the connecting hole 221 to directly discharge sewage to the outlet 12, thereby enabling the floor drain of the present invention to achieve the combined function of floor drainage and water pipe drainage.

[0045] See Figure 7 As shown, the cover assembly 3 also includes a decorative cover 202 disposed above the water inlet 201. The decorative cover 202 covers the connection hole 221, and the water inlet 201 and the decorative cover 202 form a third odor-proof structure. In some applications with only floor drainage, such as bathroom floor drainage, the connection hole is not needed, and sewer odors may overflow above the drain through the outlet 12 and the connection hole 221. The third odor-proof structure between the water inlet 201 and the decorative cover 202 prevents odors from overflowing from the connection hole 221, thus achieving an odor-proof effect. In this example, the decorative cover 202 is disposed around the connection portion 22 of the water inlet 201, and the skirt on the side wall of the decorative cover 202 cooperates with the side wall of the water inlet 201 to form the third odor-proof structure. A step is provided on the outer side of the connection hole 221 of the water inlet component 201, and a groove is provided on the lower surface of the decorative cover 202, thereby reducing the mating surface area between the water inlet component 201 and the decorative cover 202, preventing the formation of a water film between the water inlet component 201 and the decorative cover 202, which would make it difficult to open the decorative cover 202. (See also...) Figure 10 As shown, in other embodiments, the decorative cover 202 can cooperate with the step of the water inlet 201, and the step is provided on the outside of the connection hole 221 of the water inlet 201 to cooperate with the decorative cover 202 to form a third odor-proof structure.

[0046] It should be noted that connection hole 221 is not mandatory; it can be selected for applications with only ground drainage. Figure 3 The drain structure shown does not have a connection hole 221.

[0047] See Figures 1 to 10As shown, the water inlet 201 of the cover assembly 2 is usually made of metal. Therefore, when the cover assembly 2 is picked up or put down, the metal will make noise when it collides with the ground. In order to reduce the noise, the bottom of the cover assembly 2 is provided with a mating post 23. The mating post 23 is located at the bottom of the water inlet 201, or more specifically at the bottom of the water inlet groove 21 and at the outer edge of the water inlet groove 21. The mating post 23 is made of a relatively soft material such as plastic, rubber or silicone, so as to reduce the noise when picking up or putting down the cover assembly 2.

[0048] See Figure 3 and Figure 7 As shown, the bottom end of the main body 1 is provided with a mating flange 14. The inner wall of the mating flange 14 is used to connect and mate with small-diameter sewer pipes, and the outer wall of the mating flange 14 is used to connect and mate with large-diameter sewer pipes. To facilitate insertion, a guide flange 15 is provided on the inner side of the mating flange 14. The space between the mating flange 14 and the guide flange 15 is used for inserting small-diameter sewer pipes, while the outer side of the mating flange 14 is used for inserting large-diameter sewer pipes, so as to adapt to sewer pipes of different specifications.

[0049] The main body 1 is a square box-shaped structure with a water outlet 12 in the middle and a water inlet groove 21 around the water outlet 12, thus forming a structure in which water enters from all sides to the center, making the overall layout more reasonable.

[0050] Example 2

[0051] See Figures 8 to 9 As shown, the difference between this embodiment and Embodiment 1 is that the connecting part 22 of the cover assembly 2 has a square structure, and the supporting part 11 also has a square structure. Therefore, the side wall of the supporting part 11 has a flat plate structure, which makes it easy to cooperate with the one-way valve 3 to form a first odor-proof structure. Specifically, the supporting part 11 is provided with a first drain port 111 for connecting the water inlet recess 21 and the water outlet 12. The one-way valve 3 is located on one side of the supporting part 11, and the one-way valve 3 is used to cover the first drain port 111 to close the first drain port 111, thereby cutting off the fluid communication between the water inlet recess 21 and the water outlet 12. Among them, each of the two opposite side walls of the supporting part 11 is provided with a first drain port 111, and each first drain port 111 is provided with a one-way valve 3 for opening or closing the first drain port 111. The rotating shaft part 31 of the one-way valve 3 is limited by the arc-shaped groove of the supporting part 11 and the water inlet part 201 of the cover assembly 2.

[0052] See Figures 9 and 10 As shown, the structure of the cover assembly 3 is the same as that of Embodiment 1, except that it can be used for ground drainage without a connection hole, or it can have a connection hole 221 for combining ground drainage and water pipe drainage, and a decorative cover 202 is provided to close the connection hole. The decorative cover 202 and the water inlet 201 cooperate to form a third odor-proof structure.
