Description

Technical Field

[0001] The invention belongs to the technical field of floor drains, and in particular relates to an anti-overflow dual-purpose floor drain structure for a washing machine. Background Art

[0002] The washing machine floor drain is a floor drain that is connected to the washing machine drain pipe joint to drain the water discharged from the washing machine into the sewer.

[0003] At present, washing machine floor drains are mainly divided into two categories. One is the enclosed washing machine floor drain, which is sealed and connected to the washing machine joint. The first problem is that there is no fixed position, and the vibration of the washing machine easily causes the floor drain cover to jump out of the floor drain seat. The second problem is that the floor drain cover is also closed. Although it avoids the problem of water overflowing on the ground when the washing machine is draining, it completely loses the floor drainage function of the floor drain, and the user cannot drain water when mopping the floor or pouring water. The second type is the dual-purpose washing machine floor drain. Although the washing machine can take into account the ground drainage when in use, when the washing machine is draining, once the drainage volume increases instantly, the water and foam in the drain pipe will overflow to the ground through the drainage hole of the floor drain cover, thereby wetting and dirtying the ground, causing great trouble to the user, so it is necessary to improve it. Summary of the invention

[0004] To solve the problems raised in the above background technology, the present invention provides a dual-purpose washing machine floor drain structure with anti-overflow function, which has the characteristics of washing machine drain pipe and floor drainage, drainage odor prevention and anti-overflow, floor drain cover clamping installation, good shockproof performance and high applicability.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a backflow-proof dual-purpose washing machine floor drain structure, comprising a floor drain seat, a floor drain cover and a laundry drainage pipe joint, wherein the floor drain cover is mounted on the floor drain seat, the floor drain cover is provided with a floor drainage hole, the center of the floor drain cover is provided with a through hole, the floor drain seat is provided with a mounting groove, a connecting mesh is installed in the mounting groove, a boss is provided on the top of the connecting mesh, a connecting thread is provided in the boss, the laundry drainage pipe joint is installed in a screw connection manner with the connecting thread, a water flow channel is formed between the connecting mesh and the floor drain cover, the connecting mesh is provided with a discharge port communicating with the water flow channel, the connecting mesh is provided with a discharge port communicating with the water flow channel, and the connecting An embedding groove I is provided on the outer side of the mesh, an outer sealing ring is embedded in the embedding groove I, and the outer sealing ring is sealed and abutted with the outer peripheral surface of the mounting groove, an inner embedding groove II of the connecting mesh, a silicone inner sealing ring is installed in the embedding groove II, a sealing lip I is provided on the inner side of the silicone inner sealing ring, and the sealing lip I is opened and closed in the downstream direction of the discharge port, an odor-proof floor drain core is installed in the inner thread of the floor drain seat, a step portion is provided on the floor drain seat, a step surface corresponding to the step portion is provided on the floor drain cover, the top surface of the boss is flush with the step portion, the floor drain cover is abutted with the top surface of the boss, and the laundry drainage pipe joint is pressed against the floor drain cover.

[0006] As a further improvement of the present invention, the discharge port is in a cyclone shape.

[0007] As a further improvement of the present invention, a sealing lip II is provided on the outer sealing ring.

[0008] As a further improvement of the present invention, the sealing lip I is inclined to one side.

[0009] As a further improvement of the present invention, the odor-proof floor drain core includes a floor drain core body and a hinge structure. An outlet is provided at the lower part of the floor drain core body. An opening groove is provided on the floor drain core body. The hinge structure includes a hinge part and a hinge shaft. The hinge part is rotationally matched with the hinge shaft. The hinge shaft is press-fitted into the opening groove. A mounting seat is integrally provided on the hinge shaft. A valve-type sealing plate is connected to the side of the hinge part. A magnetic gravity block is embedded in the mounting seat. A side cover is inserted into the floor drain core body. A placement cavity is provided on the inner side of the side cover. A magnet is provided in the placement cavity. The magnet and the magnetic gravity block generate a restoring force by the principle of magnetic attraction to seal the outlet with the valve-type sealing plate.

[0010] After adopting the above structure, the advantages of the present invention compared with the prior art are as follows: The structure of the present invention is scientific and reasonable. Through the design of the connecting mesh, the use effect of the washing machine floor drain is greatly improved, with high applicability, convenient maintenance, and low cost; the sealing lip I is arranged to open and close in the downstream direction of the discharge port, and the silicone inner sealing ring is fixed on the outside, and its sealing lip I opens inward. Compared with the traditional prior art, this structure is relatively unique and has better usability; when not in the drainage state, the silicone inner sealing ring utilizes its own self-elastic toughness, and its sealing lip I abuts against the inner bottom of the connecting mesh, which can achieve a good sealing effect on the discharge port; when the washing machine is draining, it is installed in a threaded manner by using the connection thread between the laundry drain pipe joint and the connecting mesh. This structure enables the washing machine drainage to directly reach the anti-odor floor drain core, thus achieving a better direct drainage effect. Since the sealing lip I of the silicone inner sealing ring closes the discharge port, even if the drainage volume increases instantaneously, the water and foam in the underground drain pipe will not overflow back to the ground through the discharge port, having a good anti-overflow effect and avoiding causing trouble to users; when draining the ground, the water on the ground enters through the ground drain hole and reaches the flowing water channel. Once the gravity of the water in the flowing water channel exceeds the bearing capacity of the sealing lip I, the sealing lip I will deviate downward to open the discharge port, and then the water in the flowing water channel is discharged into the anti-odor floor drain core through the discharge port and then discharged into the sewer, thus achieving a better flowing-down effect. This structure has a good anti-odor effect and, when combined with the anti-odor floor drain core, forms two anti-odor measures; adopting this structure, the laundry drain pipe joint, the floor drain cover, the connecting mesh and the floor drain seat are tightly installed, and the mutual limiting installation effect is better. The connecting mesh is installed in a threaded manner with the laundry drain pipe joint, and the laundry drain pipe joint presses against the floor drain cover, making the floor drain cover installed in a clamped manner, and having better shock-proof performance.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment

[0019] Please refer to Figures 1-4 , the present invention provides a technical solution: an anti-backflow dual-purpose washing machine floor drain structure, including a floor drain base 10, a floor drain cover 11 and a washing machine drain pipe joint 12. The floor drain cover 11 is installed on the floor drain base 10. A floor drain hole 13 on the ground is provided on the floor drain cover 11. A through hole 14 is provided at the center of the floor drain cover 11. A mounting groove 15 is provided on the floor drain base 10. A connecting mesh 16 is installed in the mounting groove 15. A boss 17 is provided at the top of the connecting mesh 16. A connecting thread 18 is provided in the boss 17. The washing machine drain pipe joint 12 is installed in a screwed manner with the connecting thread 18. A water flow channel 19 is formed between the connecting mesh 16 and the floor drain cover 11. The connecting mesh 16 is provided with a discharge port 20 communicating with the water flow channel 19. An outer sealing ring 22 is embedded in a mounting groove I 21 on the outer side of the connecting mesh 16. The outer sealing ring 22 is in sealing contact with the outer peripheral surface of the mounting groove 15. A mounting groove II 23 is embedded on the inner side of the connecting mesh 16. A silica gel inner sealing ring 24 is installed in the mounting groove II 23. A sealing lip I 25 is provided on the inner side of the silica gel inner sealing ring 24. The sealing lip I 25 is arranged to open and close in the downstream direction of the discharge port 20. An anti-odor floor drain core 26 is installed in the floor drain base 10 by internal threading. A step portion 27 is provided on the floor drain base 10. A step surface 28 corresponding to the step portion 27 is provided on the floor drain cover 11. The top end surface of the boss 17 is flush with the step portion 27. The floor drain cover 11 abuts against the top end surface of the boss 17. The washing machine drain pipe joint 12 abuts against the floor drain cover 11.

[0020] In this implementation scheme, the structure is scientifically reasonable. Through the design of the connecting mesh 16, the use effect of the washing machine floor drain is greatly improved, with high applicability, convenient maintenance, and low cost; the sealing lip I25 is arranged to open and close in the downstream direction of the discharge port 20, and the silica gel inner sealing ring 24 is fixed on the outside, and its sealing lip I25 opens and closes inward. Compared with the traditional prior art, this structure is relatively unique and has better usability; when not in the drainage state, the silica gel inner sealing ring 24 utilizes its own self-elastic toughness, and its sealing lip I25 abuts against the inner bottom of the connecting mesh 16, which can achieve a better sealing effect on the discharge port 20; when the washing machine is draining water, it is installed in a threaded manner by using the connecting thread 18 between the laundry drain pipe joint 12 and the connecting mesh 16. This structure enables the washing machine to drain water directly to the anti-odor floor drain core 26, thus achieving a better direct drainage effect. Since the sealing lip I25 of the silica gel inner sealing ring 24 closes the discharge port 20, even if the drainage volume increases instantaneously, the water and foam in the underground drain pipe will not overflow to the ground through the discharge port 20, having a better anti-overflow effect and avoiding causing trouble to users; when draining water on the ground, the water on the ground enters through the ground drain hole 13 and reaches the flowing water channel 19. Once the gravity of the water in the flowing water channel 19 exceeds the bearing capacity of the sealing lip I25, the sealing lip I25 will deviate downward to open the discharge port 20, and then the water in the flowing water channel 19 will be discharged into the anti-odor floor drain core 26 through the discharge port 20 and then discharged into the sewer, thus achieving a better flowing-down effect. This structure has a good anti-odor effect and, when combined with the anti-odor floor drain core 26, forms a two-way anti-odor; adopting this structure, the laundry drain pipe joint 12, the floor drain cover 11, the connecting mesh 16, and the floor drain seat 10 are tightly installed, and the limiting installation effect between them is better, enabling the floor drain cover to be installed in a clamped manner and having better shockproof performance.

[0021] Specifically, the laundry drain pipe joint 12 passes through the through hole and is threadedly installed with the connecting mesh 16. The fitting groove I21 and the outer sealing ring 22 are installed by interference press-fitting, and the fitting groove II23 and the silica gel inner sealing ring 24 are also installed by interference press-fitting. This method makes the installation of the outer sealing ring 22 and the silica gel inner sealing ring 24 stable. Of course, there are many structural forms of the fitting groove I21 and the fitting groove II23, and they can all achieve the same effect.

[0022] Further, the discharge port 20 is in a cyclone shape.

[0023] In this embodiment, since the discharge port 20 is in a cyclone shape, the drainage speed will be accelerated, making the ground drainage smoother.

[0024] Further, a sealing lip II29 is provided on the outer sealing ring 22.

[0025] In this embodiment, through the sealing lip II29, it can be installed on the circumferential surface of the mounting groove 18 of the floor drain seat 10 to form a better sealing effect.

[0026] Further, the sealing lip I25 is inclined to one side.

[0027] In this embodiment, the sealing lip I25 is inclined to one side, so that the sealing lip I25 tightly abuts against the inner bottom of the connecting mesh 16.

[0028] Further, the odor-proof floor drain core 26 includes a floor drain core body 30 and a hinge structure. An outlet 31 is provided at the lower part of the floor drain core body 30. An opening groove 32 is provided on the floor drain core body 30. The hinge structure includes a hinge portion 33 and a hinge shaft 34. The hinge portion 33 is rotationally matched with the hinge shaft 34. The hinge shaft 34 is squeezed into the opening groove 32. A mounting seat 35 is integrally provided on the hinge shaft 34. A valve-type sealing plate 36 is connected to the side of the hinge portion 33. A magnetic gravity block 37 is embedded in the mounting seat 35. A side cover 38 is inserted into the floor drain core body 30. A mounting cavity 39 is provided on the inner side of the side cover 38. A magnet 40 is provided in the mounting cavity 39. The magnet 40 and the magnetic gravity block 37 generate a restoring force by the principle of magnetic attraction to seal the outlet 31 with the valve-type sealing plate 36.

[0029] In this embodiment, the odor-proof floor drain core 26 generates a restoring force that makes the valve-type sealing plate 36 reset to the outlet 31 by the gravity of the magnetic gravity block 37 using the lever principle, and a restoring force is generated by the principle of magnetic attraction between the magnet 40 and the magnetic gravity block 37. Furthermore, the valve-type sealing plate 36 tightly seals the outlet 31, improving the sealing performance of the outlet of the odor-proof floor drain core 26, and greatly improving the odor-proof and insect-proof effects. Of course, this odor-proof floor drain core 26 belongs to one of them. Of course, other odor-proof floor drain cores 26 can also be used, and the same effect can be achieved.

[0030] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
