Description

Technical Field

[0001] The utility model relates to the field of water supply and drainage of fixed buildings, in particular to an openable floor drain. Background Art

[0002] As an indispensable drainage component in modern architecture, floor drains' design and manufacturing processes continue to evolve and optimize with technological advancements. The technical background of floor drains spans multiple disciplines, including materials science, fluid dynamics, sealing technology, and building standards. Modern floor drains tend to use materials with excellent corrosion and wear resistance, such as stainless steel and copper alloys, to ensure durability and reliability. In terms of structural design, floor drains must not only ensure efficient drainage and prevent clogging, but also utilize a carefully designed water seal to isolate odors and prevent pests.

[0003] Some odor-proof floor drains currently on the market, such as the "new type of floor drain" disclosed in Publication No. CN211228809U, utilize a shielding plate installed below a rotating buckle. By rotating a toggle lever on the shielding plate, the filter holes on the rotating buckle and the shielding plate are controlled to stagger or overlap. This allows the shielding plate to rotate during drainage, allowing the filter holes on the shielding plate to overlap with those on the rotating buckle to achieve drainage. During daily use, the filter holes on the shielding plate and the rotating buckle can be offset to block odors. However, the shielding plate is connected to the rotating buckle and cannot be disassembled. Floor drains with rotating plates covering the filter holes are prone to debris falling between the rotating plate and the panel, causing the rotating plate to rotate unsmoothly and affecting odor isolation. Therefore, these floor drains need to be disassembled and cleaned regularly. Furthermore, these floor drains only have a single layer of odor barrier. If this barrier fails, the entire drain core must be replaced, which not only affects drainage and odor prevention, but is also very inconvenient. Summary of the Invention

[0004] In response to the shortcomings of the existing technology, the present invention provides an open-and-close floor drain. The floor drain is designed by designing an open-and-close panel into two layers, with a sandwich layer in the middle. The center of the sandwich layer is a column. Two semicircular panels are assembled and installed between the sandwich layers of the open-and-close panel. The open-and-close panel is installed on the panel base. By turning the panel paddles on the panel, the panel is driven to rotate, and the panel drain grooves on the open-and-close panel and the panel drain grooves on the panel are staggered or overlapped, ensuring the needs of drainage and odor prevention. A filter screen is installed below the open-and-close panel. The filter screen is densely covered with small holes, which can filter out some debris and hair. A small handle is installed in the center of the filter screen to facilitate the removal and installation of the filter screen for cleaning. The panel base is installed on the floor drain body. The water seal low-level plate of the panel base is inserted into the water seal high-level plate of the floor drain body, forming a water seal with a high water seal height, ensuring the functions of odor prevention and insect prevention.

[0005] The main body of the floor drain adopts a horizontal design, which makes the installation volume of the floor drain smaller, parallel to the ground, and well concealed. The drainage outlet is divided into a main drainage outlet and an auxiliary drainage outlet through two drainage outlets. The auxiliary drainage outlet can be used to connect to the drainage outlet of another floor drain to achieve centralized discharge of multiple drainage points.

[0006] The utility model achieves the above technical objectives through the following technical means.

[0007] A retractable floor drain, wherein an inlay is installed in the panel interlayer of an retractable panel, the retractable panel is connected to the panel base, the retractable panel is located above the filter screen, and both are installed inside the panel base, a paddle movable groove is provided on the panel base, a panel mounting groove is provided below the paddle movable groove, and the paddle movable groove and the panel mounting groove are distributed in a stepped manner.

[0008] Furthermore, the opening and closing panel is integrally formed, and there is a panel interlayer between the upper and lower layers of the opening and closing panel, and the upper and lower layers are connected by a column in the center of the opening and closing panel. The upper and lower layers of the opening and closing panel are both provided with a number of panel drain grooves, and the panel is also provided with a number of panel drain grooves. The panel drain grooves of the upper and lower layers cooperate with the panel drain grooves of the panel to penetrate each other.

[0009] Furthermore, the panels are semicircular in shape, and are interlocked with each other in pairs. The interlocking surfaces of the panels are provided with interlocking platforms and interlocking grooves, and the positions of the interlocking platforms and interlocking grooves on the panels are symmetrical.

[0010] Furthermore, the panel is engaged with the embedding groove and embedding platform of another panel through the embedding platform and embedding groove respectively, and panel paddles are provided at both ends of the panel.

[0011] Furthermore, the opening and closing panel is installed in the panel installation groove of the panel base, and the diameter of the paddle movable groove is larger than the diameter of the panel installation groove.

[0012] Furthermore, the panel paddle is movably installed in the paddle movable groove.

[0013] Furthermore, a filter cavity is provided below the panel mounting slot of the panel base, a filter screen mounting slot is provided at the bottom of the filter cavity, the filter screen is installed at the filter screen mounting slot, and a base mounting slot is provided outside the filter cavity.

[0014] Furthermore, a sealing contact surface is vertically provided below the base mounting groove, a water seal low-position plate is provided below the sealing contact surface, and a floor drain body is provided below the water seal low-position plate.

[0015] Furthermore, a base mounting platform is provided on the floor drain body, a main body contact surface is provided on the inner side of the base mounting platform, the base mounting platform is installed in cooperation with the base mounting groove, the main body contact surface is in surface contact with the sealing contact surface, and a water seal high-level plate is provided in the center of the floor drain body, and the water seal high-level plate and the water seal low-level plate cooperate with each other to form a water seal for the floor drain.

[0016] Furthermore, a plurality of filter holes are arranged on the filter panel, and a handle is protruding from the center of the filter panel.

[0017] The utility model has the following gain effects:

[0018] By rotating the panel paddle, the panel is driven to rotate, and the opening and closing of the panel drain groove of the opening and closing panel is further controlled to meet the drainage needs. When drainage is not required, the panel drain groove of the opening and closing panel can also be closed to cut off the gas circulation inside the room and the pipe. The interlayer design of the opening and closing panel blocks the gas, which can better prevent the gas in the sewer from entering the room and protect the indoor air. At the same time, the panel adopts a splicing design. Because the opening and closing panel is in direct contact with the sewage, it is easier for debris to get stuck between the opening and closing panel and the panel. Therefore, in order to ensure the air barrier function of the panel, the component needs to be cleaned frequently. The splicing structure does not connect the panel and the opening and closing panel through fixings, which is easier to clean, install and replace. A water seal is provided in the main body of the floor drain to further prevent insects and odor. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

[0024] Example:

[0025] like Figure 1-3 As shown, an openable floor drain comprises an openable panel 1 and a panel 2, which are assembled together and mounted on a panel base 4 together with a filter 3. The panel base 4 is connected to the floor drain body 5. The openable panel 1 is mounted above the filter 3, and the panel base 4 is mounted on the floor drain body 5.

[0026] The opening and closing panel 1 is in the form of a double-layer disc, with the disc consisting of an upper and a lower layer. The upper and lower discs have the same area and thickness, and the centers of the upper and lower discs are located on the same vertical line.

[0027] There is a cavity between the upper and lower circular discs, which serves as a panel interlayer 11. This interlayer 11 is where the opening and closing panel 1 and the inlay 2 meet. The discs on the opening and closing panel are regularly provided with a number of panel drain grooves 12, arranged in a circular pattern. The area between each panel drain groove 12 is larger than the area of ​​the panel drain grooves 12. If the area of ​​the panel drain grooves 12 is larger than the area between the panel drain grooves 12, the opening and closing panel 1 will not remain closed when drainage is not allowed, and the exchange of odors with indoor air will not be effectively blocked.

[0028] The openings of the panel drain grooves 12 on the upper circular disc of the opening and closing panel 1 overlap with the openings of the panel drain grooves 12 on the lower circular disc. This ensures that during normal drainage, the runoff of water through each panel drain groove 12 coincides with the opening of the panel drain groove 12. This ensures that the flow rate of water from the panel drain grooves 12 of the opening and closing panel 1 into the panel base is at its maximum, maximizing drainage efficiency.

[0029] In this embodiment, the panel drain groove 12 on the opening and closing panel 1 is in the shape of a sector. The area on the opening and closing panel 1 where the panel drain groove 12 can be processed can be regarded as a ring. Since the inner diameter of the ring is smaller than the outer diameter, the more reasonable choice of the shape of the panel drain groove 12 on the opening and closing panel 1 is to select the shape of the panel drain groove 12 as a sector of corresponding proportion based on the ratio of the inner diameter to the outer diameter of the ring. Alternatively, the area where the sector of the ring is to be set can be divided in advance, and the shape of the panel drain groove 12 can be designed in the divided area.

[0030] By planning the layout of the panel drain groove 12 on the opening and closing panel 1 in this way, on the one hand, the maximum drainage area can be ensured within the limited area of ​​the opening and closing panel 1, and on the other hand, the opening and closing panel 1 can achieve the deodorization function in conjunction with the inlay panel 2. In order not to affect the deodorization function, the two fan surfaces need to be separated by an area of ​​at least one fan surface.

[0031] The opening and closing panel 1 can be made of corrosion-resistant metals such as stainless steel. To improve production efficiency, increase yield, and reduce production costs, it is manufactured through mold processing and is formed in one piece. The two discs do not require any other connecting parts or support. A column at the center of the two discs connects the upper disc to the lower disc, thus forming a panel sandwich 11 between the upper and lower discs, where the opening and closing panel 1 and the panel 2 are spliced ​​together.

[0032] The panel 2 realizes the function of opening and closing the control panel by combining, splicing and interlocking with the opening and closing panel 1. The panel 2 is a semicircular thin plate. The two panels 2 can be spliced ​​together, and the shape formed by the splicing of the panels 2 is a disc-shaped thin plate. The disc-shaped thin plate formed by the two panels 2 has a small circular notch in the center. The radius of the circular notch in the center of the disc-shaped thin plate formed by the panel 2 is slightly larger than the radius of the central column of the opening and closing panel 1, which is conducive to the circular notch in the center of the disc-shaped thin plate to cooperate with the central column of the opening and closing panel 1. The central column of the opening and closing panel 1 not only serves as the rotation center of the disc-shaped thin plate formed by the panel 2, but also plays a role in limiting the installation of the disc-shaped thin plate and providing movement support.

[0033] A plurality of panel drain grooves 21 are also regularly distributed on the panel 2 . The distribution and design of the panel drain grooves 21 are the same as those of the panel drain grooves 12 on the opening and closing panel 1 .

[0034] The panel drain groove 21 on the panel 2 is also shaped like a sector. The area on the disc-shaped thin plate formed by the panel 2 where the panel drain groove 21 can be processed can be regarded as a ring. Since the inner diameter of the ring is smaller than the outer diameter, the more reasonable choice of the shape of the panel drain groove 21 on the disc-shaped thin plate formed by the panel 2 is to select the shape of the panel drain groove 21 as a sector of corresponding proportion based on the ratio of the inner diameter to the outer diameter of the ring. Alternatively, the area where the sector of the ring is to be set can be divided in advance, and the shape of the panel drain groove 21 can be designed based on the divided area.

[0035] The panel drain groove 21 on the panel 2, which is assembled into a disc-shaped thin plate, can overlap with the panel drain groove 12 on the opening and closing panel 1. The area of ​​the panel drain groove 21 on the panel 2 can be slightly larger than the area of ​​the panel drain groove 12, so that when draining, the runoff of water can reach the maximum drainage area. At the same time, it must be noted that the area of ​​the board separating the two panel drain grooves 21 on the panel 2 must be larger than the area of ​​the panel drain groove 21. This ensures that when the floor drain is not draining, the panel drain groove 12 of the opening and closing panel 1 can be effectively closed, isolating odors and pests in the sewer, protecting the indoor environment and indoor air quality, and protecting the health of users.

[0036] The mating surface of panel 2 is provided with a boss 23 and a groove 24. The boss 23 is a protruding part of the mating surface, while the groove 24 is a missing part of the mating surface. The boss 23 is a semicircular boss, and the groove 24 is a semicircular groove. The two panels 2 are connected by the boss 23 on panel 2 fitting into the groove 24 on the other panel 2, and vice versa. Although there is no fixed connection between the two panels 2, when the panels 2 are joined to the opening and closing panel 1 and the opening and closing panel 1 is installed in the panel base 4, the panels 2 are effectively restrained and fixed. This connection method also simplifies assembly and disassembly of the panels 2 and opening and closing panel 1, and is more convenient for cleaning. If either the opening and closing panel 1 or panel 2 is damaged, only the damaged part needs to be replaced. Compared to the structure of the reference document, which requires replacing the majority of the floor drain core, this is more economical and environmentally friendly.

[0037] Arc-shaped panel paddles 22 are located at both ends of the mating surface of panel 2. When the two panels 2 are joined, the end faces of the panel paddles 22 mate with each other. After panel 2 and opening and closing panel 1 are assembled, the height of the panel paddles 22 on panel 2 is higher than the highest point of the upper circular disc of opening and closing panel 1. This facilitates user-controlled alignment of panel drain grooves 12 of opening and closing panel 1 with panel drain grooves 21 of panel 2, as well as closing panel drain grooves 12 of opening and closing panel 1.

[0038] The filter 3 is designed in a disc shape, featuring a sophisticated structure and high functionality. It not only filters on its surface but also extends downward to form a circular protrusion, known as the filter mounting platform 31. This design allows the filter 3 to be securely mounted on the panel base 4, secured via the filter mounting slot 45 within the panel base 4.

[0039] The filter 3 features numerous carefully designed filter holes 33 in a hexagonal pattern arranged in a circular pattern. This arrangement is not only aesthetically pleasing but also helps improve filtration efficiency, ensuring uniformity and effectiveness during the filtration process. The hexagonal design also helps increase the strength of the filter, making it more durable.

[0040] A curved handle 32 is designed at the center of the filter 3. This handle greatly facilitates cleaning the filter. The user can easily remove the filter 3 from the panel base 4 for cleaning or replacement, and then easily reinstall it.

[0041] The panel base 4 is the main part of the floor drain. The opening and closing panel 1, the panel 2, and the filter 3 of the floor drain all need to be installed on the panel base 4. The upper end of the panel base 4 is provided with a paddle movable groove 41 and a panel mounting groove 42. The paddle movable groove 41 is located above the panel mounting groove 42. The paddle movable groove 41 and the panel mounting groove 42 are arranged in a stepped manner. Below the panel mounting groove 42 is a filter chamber 47, which is used to form a buffer zone between the opening and closing panel 1 and the filter 3. The filtered garbage can be temporarily stored in a small amount in the filter chamber 47 waiting for the user's subsequent cleaning, without affecting the current drainage needs.

[0042] The bottom of the filter chamber 47 is a filter mounting groove 43 for connecting and installing with the filter mounting platform 31 of the filter 3. The annular plate extending downward from the filter mounting groove 43 is the water seal low plate 44. The lowest point of the water seal low plate 44 is the lowest point of the effective water seal. The end of the platform extending outward from the filter mounting groove 43 is the base mounting groove 45 for installing the panel base 4 and the floor drain body 5. The part extending downward from the inner side of the base mounting groove 45 is the sealing contact surface 46. The base mounting groove 45 is connected and installed with the base mounting platform 51 of the floor drain body 5, and the sealing contact surface 46 is in contact and sealed with the body contact surface 53. When the floor drain is installed, the part of the filter mounting groove 43 extending outward will be buried underground or covered with tiles, thereby further fixing the panel base 4.

[0043] Because the bottom of the panel base 4 is in direct contact with sewage, the sealing contact surface 46 and the main body contact surface 53 are in direct contact. The sealing performance here is very high, and glue is generally used to fix and seal them to prevent corrosion between the sealing contact surface 46 and the main body contact surface 53 during long-term use, resulting in the sealing between the sealing contact surface 46 and the main body contact surface 53 being broken, allowing sewage to seep into the room and damage tiles or floor structures.

[0044] The floor drain body 5 is a drainage component that adopts a horizontal row design and has a smaller installation volume. An annular boss is provided on the top to connect to the panel base, and a plate-shaped circular ring is provided at the bottom, which is a water seal high plate 52. The water seal low plate 44 is sleeved in the cavity of the water seal high plate 52. The highest point of the water seal high plate 52 is higher than the lowest point of the water seal low plate 44. The vertical distance difference between the two is more than 50mm and can reach up to 100mm. The highest point of the water seal high plate 52 and the lowest point of the water seal low plate 44 form an effective water seal section. The water seal height cannot exceed the highest point of the water seal high plate 52. The excess water will overflow. When the lowest point of the water seal is lower than the lowest point of the water seal low plate 44, the water seal fails and cannot play the role of preventing odor and insects. There are two drain outlets at both ends of the bottom of the floor drain body 5, one end is the main drain outlet 55, and the other end is the auxiliary drain outlet 54. The auxiliary drain outlet 54 is connected to the drainage pipes of other floor drains. The main drain outlet 55 will gather the water flowing into the auxiliary drain outlet 54 and the water leaking from the floor drain itself to the main drain outlet 55 and discharge them together into the sewer pipe.

[0045] During daily use, the panel drain groove 21 of the panel 2 is completely offset from the panel drain groove 12 of the opening and closing panel 1, so that the opening and closing panel 1 remains closed, isolating odors and blocking pests. At the same time, debris cannot fall into the floor drain through the panel drain groove 12 of the opening and closing panel 1.

[0046] At the beginning of the drainage process, the user moves the panel paddle 22 on the panel 2 to allow the panel drain groove 12 of the opening and closing panel 1 in a completely dislocated state to completely overlap with the panel drain groove 21 of the panel 2. At this time, the water flows through the drain groove of the opening and closing panel 1 into the filter chamber 47, and the runoff of the water reaches the maximum.

[0047] During the drainage process, the water flow is inevitably mixed with some debris. Smaller granular debris will not block the sewer and will not affect the use of the sewer. Therefore, such debris will fall into the floor drain body 5 through the filter holes 33 of the filter mesh 3. However, larger debris, such as paper balls and other large debris with the potential risk of clogging the drainage pipe, and hair and other debris that will adhere to a certain part of the floor drain and are difficult to drain out, will not be able to pass through the filter holes 33 of the filter mesh 3 and will be retained in the filter chamber 47. After the drainage is completed, the user will have to actively clean up such debris.

[0048] The filter holes 33 have small diameters and are densely arranged, and the connection between the filter screen 3 and the floor drain body 4 is sealed, which easily produces a siphon effect during the drainage process, speeds up the drainage speed, and improves the drainage efficiency.

[0049] When the sewage falls into the water seal liquid column formed by the water seal low plate 44 and the water seal high plate 52, the sewage will overflow from the highest point of the liquid level of the water seal high plate 52, enter the main drain outlet 55 of the floor drain body 5, and finally merge with the auxiliary drain outlet 54 and be discharged into the next drainage pipe, completing the complete drainage process.

[0050] The local drain controls the opening and closing of the opening and closing panel 1 by toggling the panel 2, thereby controlling whether the floor drain is in the draining state. The local drain is simple to operate and, after sealing the panel drain channel 12, effectively isolates odors and deters pests. The simple and reliable splicing structure of the opening and closing panel 1 and panel 2 makes it easy to replace damaged parts, requiring fewer replacement components. This saves costs and is more environmentally friendly. The high water seal ensures minimal water seal failure, further blocking odors and deterring pests.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
