Description

  The present invention belongs to the field of architectural structures, and specifically relates to a deep-sealed deep-sealed floor drain with complete deodorization.

  Floor drains are an important connection between the drainage pipe system and the indoor ground, and as an important part of a residential drainage system, its performance directly affects indoor air quality. Different floor drains are selected in different application scenes, and at present, general residential floor drains are mainly classified into two categories: eccentric block type downward flipboard floor drains and deep sealed floor drains. The eccentric block type downward flipboard floor drain is also called a T-type floor drain and has a large cross section of water and a high drainage speed. The eccentric block type downward flipboard floor drain is mainly used in balconies, kitchens, etc. where there is less hair, the drainage speed is high, and the drainage volume is large. The deep sealed floor drain is also called the U-shaped floor drain The drainage channel is U-shaped and the drainage speed is slow, but due to the sealing effect of its structural shape, it is possible to realize good sealing deodorization, and it is easy to disassemble and wash, and it is difficult for the hair to be clogged, Generally, it is used in bathrooms that require a drainage speed and have a lot of dirty hair. However, conventional deep sealed floor drains cannot be said to be completely deodorized, and when the water stored in the U-shaped conduit is completely volatilized (for example, when the bathroom is not used for a long time, or when the weather is poor). If it is hot), the deep sealing floor drain will lose its water sealing effect, increasing the odor of the sewer and adversely affecting the air quality of the entire bathroom.

  In order to solve this problem, Chinese Utility Model CN206956968U discloses an improved reinforced sealed floor drain that reduces the volatilization rate of sealing water by providing a floating seal in a water sealing cylinder. If the speed is slowed down, the sealing effect is prolonged, the bathroom is not used for a long time, and the weather is very hot, the water for sealing is also completely volatilized. The new floating seal sinks to the bottom and the sewage line still communicates with the indoor air above the floor drain, failing to achieve a complete deodorizing effect.

  In addition, there is a technique of using a permanent magnet to control the opening and closing of a sewer pipe port to achieve complete sealing and deodorization.For example, in Chinese Patent CN10174784B, when the weight of water is larger than the magnetic force, the sealing plate is A self-sealing deep-sealed floor drain is disclosed that opens downward, drains until the weight of water is less than the magnetic force, and the sealing plate is suctioned upward and closed. There are at least three improvements to the floor drain structure disclosed in the patent. First, when the guide post sleeve for setting two permanent magnets has a sealed structure, when the permanent magnet and the sealing plate connected to it move up and down, one end is sealed like a syringe and the other end is closed. The actual use of the patent is not very good because the air pressure is very difficult to move so that it is very difficult to pull out and push it, while the guide post sleeve for setting two permanent magnets is In the case of an unsealed structure, water and other dirt easily enter the guide post sleeve, which also has a bad effect on the magnetic attraction effect. Secondly, the method of controlling the opening and closing of the sealing plate by overcoming the magnetic force by the weight of the water requires the magnetic force and the volume of the cylinder to be accurately designed, thus increasing the difficulty of the design. Different calculations and designs are required for different floor drains. Third, since the hermetic deodorization can be achieved by controlling the opening and closing of the sealing plate by the weight and magnetic force of the water, the water sealing structure at the lower end is actually a redundant design, and there is no further practicality.

  In view of the above, an object of the present invention is to provide a completely deodorized deep sealed floor drain and optimize and improve the conventional deep sealed floor drain structure so that the water for sealing the floor drain is reduced. Even when completely volatilized, ensure that complete deodorization is achieved, and at the same time, the amount of modification to the existing deep sealed floor drain structure is small, the application range is wide, the operation principle is reasonable, and the existing Make full use of the water sealing technology and avoid redundant design.

  To achieve the above object, the present invention provides the following technical solutions.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
Example 1
As shown in FIGS. 1 to 3, the completely deodorized deep sealed floor drain includes a pre-buried box 1, a watertight canister 2, a lining pipe 3, and a filtration system. The preliminary buried box 1 is fixedly attached to a floor surface at an upper end of a drain pipe (not shown in the figure), an upper surface thereof is below the ground of the house, and an intermediate portion is opened downward to form a drain passage. The water bottle 2 is suspended from the lower opening of the preliminary buried box 1, the bottom end thereof is sealed, and a water outlet 4 communicating with a drain pipe is opened on both side walls. 2 are coaxially hung and arranged inside, and are spaced apart from the inner wall of the water sealing tube 2 by a certain distance in a radial direction for normal drainage water passage, and openings are provided at both upper and lower ends of the lining pipe 3. Is lower than the horizontal height of the water outlet 4 and at a certain distance from the bottom of the watertight canister 2 so as to form a watertight area, the filtration system is arranged to form a slag filter for the water flow. Upper part of buried box 1 A floating sealing ring 5 installed in a region between the mouth and the upper opening of the lining tube 3 and having an intermediate opening on the inner wall surface at the lower end of the lining tube 3 is connected by welding or integral molding. A floating sealing plate 6 is connected to the upper side, and the maximum horizontal cross-sectional diameter of the floating sealing plate 6 is set to the inner diameter of the lining tube 3 so that the water flow can flow into the watertight canister 2 without clogging the lining tube 3. Smaller, and even if the floating sealing plate 6 moves horizontally to any extreme position in the lining tube 3, its vertical projection completely covers the intermediate opening of the floating sealing ring 5, 6 is floating sea Be attached to the upper surface of the ring the ring 5, covering the openings of the floating sealing ring 5, it is possible to secure the sealing the lining tube 3.

  Furthermore, the filtration system used in this embodiment comprises a panel 7, a filter cover 8 and a lower filter disc 9 which are installed at different heights of the pre-buried box 1 at successively spaced intervals from top to bottom. Including. The upper surface of the panel 7 and the upper surface of the preliminary burying box 1 are flush with each other, and drain holes are respectively formed on the panel 7, the filter cover 8 and the lower filter disk 9, and the drain holes are gradually reduced. The system adopts a triple filtration system in which the filtration capacity is gradually improved, the water flow flowing into the lining pipe 3 is cleaner, the dirt is smaller, and the solid dirt on the floating sealing plate 6 and the floating sealing ring 5 is used. Avoid clogging and finally ensure normal use of the deep sealed floor drain.

  Further, the floating sealing plate 6 used in the present embodiment has a solid structure made of a lightweight material having a lower density than water, for example, a plastic material made of polyethylene, and the floating sealing plate 6 of the present embodiment is flat. It has a simple circular block shape.

  As for the principle of operation, as shown in FIG. 1, when the floor drain normally operates, the discharged water stream is sequentially slug-removed from the pre-buried box 1 through the panel 7, the filter cover 8 and the lower filter disk 9. After being filtered and filtered, the water flows into the lining pipe 3 and accumulates in the watertight casing 2. When the water level in the watertight casing 2 becomes higher than the edge of the lower opening of the water outlet 4, the water flow overflows from the water outlet 4 and the water flows out. It flows into the drain pipe communicating with the outlet 4, and moves to the next discharge procedure. At this time, when the sewage drained from the floor drain is exhausted, the water level in the water sealing tube 2 and the lining pipe 3 of the floor drain reaches an equilibrium state, and normal water sealing is formed.

  As shown in FIG. 2, when the bathroom is not used for a long time and the weather is very hot, the water for water sealing in the floor drain gradually evaporates, and the water sealing tube 2 communicates with the lining pipe 3. Therefore, the water level for sealing the water therein gradually decreases, and at this time, the height of the floating sealing plate 6 at the lining pipe 3 also gradually decreases, and the water flows between the lower surface of the floating sealing plate 6 and the floating sealing ring 5. When the upper surface is volatilized until it coincides with the upper surface, that is, when the closed critical state is reached, the floating sealing plate 6 cooperates with the floating sealing ring 5 to seal the lower end opening of the lining tube 3, that is, isolates the lining tube 3 from the watertight tube 2. Even if the water in the lining pipe 3 is completely volatilized and dried, or the water in the water bottle 2 is completely volatilized and dried, the water is discharged from the drainage pipe. Odor pending in sealing water bottles 2 without spreading indoors through the lining pipe 3, it is possible to realize a complete deodorization.

  When it is desired to recover the floor drain from the state of FIG. 2 to the normal operation state of FIG. 1, it is sufficient to use the floor drain and allow the water that needs to be drained to flow into the floor drain. The lining pipe 3 is gradually raised by the buoyancy of the water therein, and the water level in the lining pipe 3 reaches a critical state for floating as shown in FIG. 3, and the floating sealing plate 6 is moved in the direction a in FIG. The water flow that moves along and flows through the gap between the floating sealing plate 6, the lining pipe 3, and the floating sealing ring 5, that is, flows in the direction b in FIG. The state recovers from the state shown in FIG. 3 to the state shown in FIG. 1 and achieves an equilibrium state between normal drainage and sealing.

  As described above, according to the completely deodorized deep sealed floor drain described in the present embodiment, two structures of the floating sealing ring 5 and the floating sealing plate 6 can be added to the existing deep sealed floor drain structure. Since the amount of remodeling is small, the principle of operation is simpler than that of the method of controlling the opening and closing of the drainage channel by overcoming magnetic force by the weight of water, there is no complicated calculation and design, and the scope of application is It is wide, easy to spread and takes full advantage of existing sealing technology, avoids redundant design, is very economical and practical.

Example 2
As shown in FIGS. 4 and 5, unlike the first embodiment, in the present embodiment, a magnetic ring 10 that can be magnetically coupled to each other is embedded in the upper surface of the floating sealing ring 5 and the lower surface of the floating sealing plate 6. The ring 10 increases the coupling effect between the floating sealing ring 5 and the floating sealing plate 6 and the sealing robustness. During the design, the magnetic ring 10 with an excessive magnetic force is not used here, and the floating sealing plate 6 completely fills the lining tube 3 with water, and then the generated buoyancy is reduced by the weight of the floating sealing plate 6 and the magnetic ring 10. The floating sealing plate 6 ensures that the floor drain smoothly recovers from a dry state to a normal use state.

Example 3
As shown in FIGS. 6 and 7, unlike the second embodiment, in the present embodiment, the region of the intermediate opening of the floating sealing ring 5 has an inverted conical frustoconical structure, and the circumferential direction of the floating sealing plate 6 is different from that of the second embodiment. Has a sealing step 61 for coupling to the surface of the truncated cone structure. Since the floating sealing plate 6 and the floating sealing ring 5 are connected by an inclined surface having a truncated conical structure and have the same horizontal distance, the floating sealing plate 6 and the floating sealing ring 5 have a connection surface larger than that of the first and second embodiments, so that the sealing performance after the connection is improved. In addition, due to the inverted-cone-shaped truncated conical structure, the floating sealing plate 6 has a certain guiding property during the descending process, and the sealing property after the connection can be similarly secured.

  As shown in FIGS. 6 and 7, the top of the floating sealing plate 6 used in this embodiment has a spherical arch structure, and the floating sealing plate 6 is integrally formed with a hollow structure. The design of the spherical arch structure at the top of the floating sealing plate 6 prevents the water flow from accumulating on the upper surface of the floating sealing plate 6 as compared with the flat circular block-shaped structural design of the floating sealing plate 6 of the first and second embodiments. Increases the discharge speed of the water flow and has good dischargeability.

  As shown in FIGS. 6 and 7, the floating sealing plate 6 further includes an auxiliary structure which is depressed inward between the circumferential sealing step 61 of the floating sealing plate 6 used in the present embodiment and the spherical arch structure at the top thereof. Each auxiliary structure includes one straight step 62 and one inclined step. When the water level in the lining pipe 3 reaches a critical state of floating due to the special structure of the floating sealing plate 6 in the present embodiment, such as a truncated conical shape in the circumferential direction and a spherical arch at the top, the floating sealing plate 6 receives buoyancy. Due to the lack of a supporting surface, an auxiliary structure including the straight step 62 is designed, and the buoyancy acts on the straight step 62 to generate a vertically upward buoyancy, for example, a buoyancy in the c-direction as shown in FIGS. By the buoyancy received by the floating sealing plate 6, the weight of the floating sealing plate 6 and the magnetic force of the magnetic ring 10 can be smoothly overcome, and the floor drain can be smoothly recovered from the closed state to the normal operation state.

Example 4
As shown in FIGS. 8 to 12, unlike the third embodiment, the present embodiment further includes a backflow prevention structure. The above-mentioned backflow prevention structure has a lower cover 12 connected to the bottom surface of the floating sealing plate 6 via a rod 11, and even if the floating sealing plate 6 moves horizontally to any extreme position in the lining pipe 3. The vertical projection of the lower cover 12 completely covers the intermediate opening of the floating sealing ring 5, and the principle of the dimensional design is the same as that of the floating sealing plate 6. Can be secured to cover the opening of the floating sealing ring 5 to seal the lining pipe 3 and prevent backflow. The height of the rod 11 and the lower cover 12 in the vertical direction is as follows. When the floor drain is normally sealed, the lower cover 12 and the floating seal There is a certain distance from the lower surface of the ring 5, and as shown in FIG. 8, the water flow is discharged smoothly, the floating sealing plate 6 is brought into a closed critical state, and the intermediate opening of the floating sealing ring 5 is closed. In this case, there is a certain distance between the lower cover 12 and the bottom of the water bottle 2, and as shown in FIG. 9, it is possible to prevent the sealing action from being weakened by pushing up the floating sealing plate 6.

  When the drainage pipe starts to flow backward due to a problem such as clogging, the backflowed sewage continuously returns to the watertight canister 2 and the lining pipe 3 via the water outlet 4 and finally the water level rises. When the water level rises to the backflow prevention critical state in FIG. 10, the lower cover 12 covers the opening of the floating sealing ring 5 from the lower end and closes, and the lining pipe 3 and the water sealing canister 2 are closed. Even if the water level in the watertight envelope 2 continues to rise to the extreme backflow state as shown in FIG. 11, the water level in the lining pipe 3 does not continue to rise, so that the sewage flows back from the preliminary buried box 1 to the room. In addition, indoor environmental hygiene can be guaranteed in the case of a drainage pipe failure.

  When the troubles such as clogging of the drainage pipe are resolved and, for example, the sewerage pipe system is dredged, the water level in the water seal tube 2 naturally drops to the level of the lower edge of the water outlet 4, and at this time, the lining pipe 3 Is higher than the water level in the watertight casing 2 and the lower cover 12 keeps the floating sealing ring 5, the watertight casing 2 and the lining pipe 3 isolated. In this case, the panel 7, the filter cover 8 and the lower filter disc 9 When the floating sealing plate 6 is pushed downward in the direction d in FIG. 12 with a stick-shaped hard object (such as chopsticks), water collected in the lining tube 3 is dispensed along the direction e in FIG. 2 and can be restored to the state of normal use and normal sealing of FIG. Of course, without removing the panel 7, the filter cover 8, and the lower filter disc 9, several thin wires may be pulled down from the drain hole and the floating sealing plate 6 may be pushed downward in the direction d in FIG.

  In order to ensure the convenience of improvement of the existing deep-sealed floor drain structure, both ends of the rod 11 are designed in a screw shape, and are screwed into screw holes on the floating sealing plate 6 and the lower cover 12, respectively. Connection. Also, the lower cover 12 may be designed to have the same structure as the floating sealing plate 6, and may be arranged symmetrically with the floating sealing plate 6 in the horizontal direction. For example, the lower surface of the floating sealing ring 5 is designed to have a truncated cone shape, The upper surface of the lower cover 12 may be designed in a corresponding truncated cone shape, and a magnetic ring may be embedded between the lower cover 12 and the coupling surface of the floating sealing ring 5 to improve the sealing performance. In a similar design, the number of parts and the number of openings in the mold are reduced, and the design and manufacturing costs are reduced. When the shapes of the floating sealing plate 6 and the lower cover 12 are unified, both members are actually one member, the number of parts is reduced, and productivity is improved.

  Finally, the above preferred embodiments are not limiting and are merely illustrative of the technical solution of the present invention, and the present invention has been described in detail by the above preferred embodiments. It is to be understood that various changes may be made in the form and details described above without departing from the scope.
