[0001] The present invention relates to the field of bathroom equipment, in particular to a washing machine drainage floor drain core and a floor drain structure comprising the washing machine drainage floor drain core. Background Art

[0002] The floor drain is a crucial interface between the drainage system and the indoor floor, and the floor drain core is installed within it. As a crucial component of a residential drainage system, the floor drain core not only ensures normal drainage but also prevents odors and insects from entering the bathroom through the drain. Washing machines typically discharge large volumes of wastewater in a short period of time, making it difficult for ordinary floor drains to quickly remove large amounts. This is especially true when there is already wastewater on the ground that has not yet been drained through the drain. This wastewater can easily accumulate and spread on the floor, significantly impacting the user experience. Summary of the Invention

[0003] In view of the problem existing in the prior art: ordinary floor drains are difficult to discharge a large amount of sewage in a short time when draining a washing machine, which causes sewage to accumulate and spread on the ground. The purpose of the present invention is to provide a floor drain core for washing machine drainage. By optimizing the structure of the floor drain core, the floor drain core has two independent drainage channels for washing machine drainage and ground drainage, and both drainage channels have normal insect and odor prevention functions. It has the advantages of simple and durable structure, low failure rate and strong applicability, which is convenient for large-scale promotion and application.

[0004] To achieve the above object, the technical solution of the present invention is: A washing machine drainage floor drain core comprises a core body and a flap, the core body being provided with a water inlet and a second drain outlet, the flap being hinged to the core body and covering and shielding the second drain outlet, the water inlet being connected with the second drain outlet inside the core body to form a second drainage channel, the core body being further provided with a guide pipe, an isolation plate and a first drain outlet, the isolation plate being arranged between the guide pipe and the inner wall of the core, the guide pipe being fixed to the inside of the core body through the isolation plate and the outer wall of the guide pipe not contacting the inner wall of the core, the bottom of the guide pipe being connected with the first drain outlet to form a first drainage channel, the first drainage channel and the second drainage channel each draining water independently.

[0005] The present invention is further configured such that: the isolation plate is arranged around the connection between the guide pipe and the first drain outlet.

[0006] The present invention is further configured as follows: the core body and the guide tube are both arranged vertically, the axis of the guide tube coincides with the axis of the core body, and the water inlet is an annular gap between the outer wall of the guide tube and the inner wall of the core body.

[0007] The present invention is further configured such that: the first drain outlet is located above the second drain outlet on the core.

[0008] The present invention is further configured such that: the first drain outlet and the second drain outlet are located on the same side of the core.

[0009] The present invention is further configured to include: a seal, which is used to strengthen the sealing of the flap to the second drain outlet, and the seal includes a movable magnetic block and a fixed magnetic block corresponding to each other, the movable magnetic block is fixed to the bottom of the flap and is located on the side of the flap away from the second drain outlet, the fixed magnetic block is arranged at the bottom of the core body near the second drain outlet, and the fixed magnetic block and the movable magnetic block are arranged opposite to each other and have opposite magnetic properties.

[0010] The present invention also provides a floor drain structure, including a floor drain body, a mounting seat and a floor drain cover, wherein the mounting seat is located inside the floor drain body, and the floor drain cover is arranged on the floor drain body. It also includes the above-mentioned washing machine drainage floor drain core, wherein the core is installed in the floor drain body through the mounting seat, and the guide pipe is connected to the drainage pipe of the washing machine.

[0011] The present invention is further configured as follows: an installation block is further provided on the outer wall of the core body, an installation groove is provided on the inner wall of the mounting seat, and the core body and the mounting seat are connected and installed through the installation block and the installation groove.

[0012] The present invention is further configured to include a transfer pipe, wherein a through hole is provided on the floor drain cover, one end of the transfer pipe passes through the through hole and is connected to the guide pipe, and the other end of the transfer pipe is connected to the drain pipe of the washing machine.

[0013] The present invention is further configured as follows: the adapter tube includes a connecting head, a fixing clamp and a fixing ring, the connecting head is located at one end where the adapter tube is connected to the guide tube, the fixing clamp is located above the connecting head, the diameter of the connecting head is smaller than the diameter of the through hole and the diameter of the fixing clamp is larger than the diameter of the through hole, the fixing ring is located below the funnel cover and the fixing ring is threadedly engaged with the connecting head.

[0014] In summary, the beneficial effects achieved by the present invention are as follows: (1) The annular water inlet between the outer wall of the guide pipe and the inner wall of the core is connected to the second drain port of the core, forming a second drainage channel; the guide pipe located inside the core is connected to the first drain port of the core, forming a first drainage channel; due to the presence of the isolation plate, the first drainage channel and the second drainage channel are not connected to each other and are independent of each other. The ground drainage enters the water inlet and is discharged from the second drain port, while the washing machine drainage enters the guide pipe and is directly discharged from the first drain port. On the one hand, the washing machine drains directly through the pipe, which greatly improves the flow rate and flow rate of drainage compared to the conventional ground drainage method of natural flow through the floor drain; on the other hand, it allows the ground drainage and washing machine drainage to proceed simultaneously, thus completely solving the problem of water accumulation on the ground caused by large amounts of water discharged from the washing machine in a short period of time; (2) Due to the presence of hair and other dirt on the ground, the dirt carried in the sewage discharged from the second drain outlet is easily attached to the second drain outlet, resulting in a decrease in the sealing performance of the flap to the second drain outlet. However, the washing machine sewage discharged from the first drain outlet contains less solid dirt and has a faster flow rate. Therefore, the first drain outlet located on the same side of the core and higher than the second drain outlet can use the washing machine sewage to impact and flush the area around the second drain outlet, which has the effect of removing solid dirt and strengthening the sealing performance; (3) The adapter pipe connected to the washing machine drain pipe passes through the floor drain cover and is directly connected to the guide pipe. This not only facilitates the connection between the washing machine drain pipe and the guide pipe, but also prevents odor flies in the sewer from entering the indoor environment through the washing machine drainage channel due to loose connection or poor sealing between the washing machine drain pipe and the guide pipe.

DETAILED DESCRIPTION

[0018] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. For ease of explanation, the terms "vertical", "horizontal", "left", "right", "up", "down", "inside", "outside", "bottom", etc. used in this specification to indicate the orientation or position relationship are based on the orientation or position relationship shown in the drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, they should not be understood as limiting this application.

[0019] It should be noted that the embodiments of the present invention and the features involved in the embodiments can be combined with each other without conflict. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] Example 1

[0021] As attached Figure 1-8 As shown, a washing machine drainage floor drain core includes a core body 1, a flap 2 and a sealing member 3.

[0022] The core 1 is a vertically arranged tubular structure with a water inlet 13 at its upper end. The interior of the core 1 serves as a sewage flow channel. The core 1 gradually converges from its upper end to its lower end, and a first drain outlet 14 and a second drain outlet 15 are provided on the same side of the core 1.

[0023] The second drain port 15 is semicircular and located at the bottom of the core 1. The water inlet 13 is connected to the second drain port 15 to form a second drainage channel inside the core 1. Sewage flowing into the core 1 from the water inlet 13 flows out from the second drain port 15 and into the sewage pipe.

[0024] The flap 2 is a flat plate structure, and its shape and size are adapted to the second drain outlet 15 , so that the flap 2 can completely cover and seal the drain outlet, preventing odor or flying insects in the sewage pipe from entering the room through the second drain outlet 15 .

[0025] The top of the flap 2 is provided with a hinge shaft that cooperates with the core 1, thereby realizing the hinge connection between the flap 2 and the core 1. When sewage in the second drainage channel flows out of the second drainage port 15, the flap 2 is impacted by the sewage and rotates toward the side away from the second drainage port 15.

[0026] In particular, please refer to the attached Figure 2 The second drain opening 15 of the core 1 is not vertically arranged but is inclined and extended toward the direction of the flap 2. That is, the second drain opening 15 is arranged slightly upward. Therefore, in a natural state, the flap 2 can cover the second drain opening 15 under the action of its own weight and exert a certain pressure on the second drain opening 15.

[0027] The sealing member 3 is used to enhance the sealing performance of the flap 2 to the second drain port 15 . In this embodiment, the sealing member 3 includes a movable magnetic block 31 and a fixed magnetic block 32 corresponding to each other.

[0028] The movable magnet 31 is fixed to the center of the bottom of the flap 2, located on the side of the flap 2 facing away from the second drain outlet 15. When the flap 2 is impacted by sewage and rotates, the movable magnet 31 acts as a counterweight on the flap 2, relying on gravity to force it to close the second drain outlet 15. Furthermore, because the movable magnet 31 is farthest from the hinge axis between the flap 2 and the core 1, it functions most effectively as a counterweight.

[0029] The fixed magnet 32 ​​is located at the bottom of the core 1, near the second drain outlet 15. Specifically, the core 1 has a recessed slot at the center of the bottom of the second drain outlet 15, with the slot's opening facing away from the opening of the second drain outlet 15. The fixed magnet 32 ​​is embedded in this slot and positioned near the flap 2. As a result, the fixed magnet 32 ​​and the movable magnet 31 are located on opposite sides of the flap 2, corresponding in position and possessing opposite magnetic properties, enabling mutual attraction.

[0030] When the flap 2 is placed on the second drain outlet 15 , the distance between the fixed magnet 32 ​​and the movable magnet 31 is minimum, and the attraction between the two is maximum, thereby maintaining a high sealing performance of the flap 2 to the second drain outlet 15 .

[0031] In some other embodiments, the seal 3 also includes a sealing soft rubber layer arranged on the flap 2 or at the edge of the second drain outlet 15. The sealing soft rubber layer can reduce the gap between the flap 2 and the second drain outlet 15, thereby improving the sealing performance.

[0032] The core 1 is further provided with a flow guide tube 11 and an isolation plate 12 .

[0033] As attached Figure 4-8 As shown, the drainage pipe 11 is a cylindrical straight pipe structure vertically arranged inside the core 1. The outer wall of the drainage pipe 11 does not contact the inner wall of the core 1. The axis of the drainage pipe 11 coincides with the axis of the core 1, and the top of the drainage pipe 11 is higher than the core 1, so that the annular gap between the outer wall of the drainage pipe 11 and the inner wall of the core 1 becomes the water inlet 13. The drainage pipe 11 is located in the center of the core 1, which can prevent the outer wall of the drainage pipe 11 from contacting the inner wall of the core 1 at the water inlet 13, ensuring that ground drainage can flow into the water inlet 13 from all directions of the core 1.

[0034] The isolation plate 12 is disposed between the guide tube 11 and the inner wall of the core 1, and the guide tube 11 is fixed inside the core 1 through the isolation plate 12. In addition, the bottom of the guide tube 11 is connected to the first drain port 14 through the isolation plate 12 to form a first drainage channel.

[0035] The isolation plate 12 is used to secure the drainage tube 11 within the core 1 and serves as a connecting plate between the drainage tube 11 and the first drain outlet 14. Therefore, the isolation plate 12 is typically positioned around the junction of the drainage tube 11 and the first drain outlet 14, thereby separating the interior of the drainage tube 11 from the interior of the core 1. Therefore, the isolation plate 12 can be configured as one or more flat or curved plates, depending on the shape of the opening at the bottom of the drainage tube 11. In this embodiment, the bottom of the drainage tube 11 is sealed and does not communicate with the interior of the core 1, but the side surfaces of the bottom of the drainage tube 11 communicate with the first drain outlet 14. Therefore, the isolation plate 12 is configured to include a horizontally arranged flat plate and two vertically arranged curved plates. This creates a first drainage channel within the core 1, but independent of the core 1's interior. Sewage entering the drainage tube 11 flows directly along the drainage tube 11 and into the sewage pipeline at the first drain outlet 14. The first and second drainage channels are each independently drained.

[0036] In this embodiment, the first drain outlet 14 and the second drain outlet 15 on the core body 1 are located on the same side of the core body 1, and the first drain outlet 14 is located directly above the second drain outlet 15, so that the sewage flowing out of the first drain outlet 14 at a high speed can be used to impact and flush the second drain outlet 15 during the downward flow, thereby removing solid dirt at the second drain outlet 15, and further enhancing the sealing performance of the flap 2 to the second drain outlet 15.

[0037] In some other embodiments, the first drain outlet 14 and the second drain outlet 15 can be arranged on different sides of the core 1, for example, they are arranged opposite to each other, and the first drain outlet 14 can also be lower than or equal to the height of the second drain outlet 15. At this time, the flow directions of sewage in the first drain outlet 14 and the second drain outlet 15 are opposite, and the first drain outlet 14 and the second drain outlet 15 do not interfere with each other when draining water.

[0038] The core 1 is also equipped with a sealing ring 16 and a mounting block 17 for mounting the core 1 in the floor drain structure. The sealing ring 16 is used to install and fix the sealing ring, thereby strengthening the sealing effect between the core 1 and the floor drain structure. The mounting block 17 is provided on the outer wall of the core 1, which enables the core 1 to form a snap fit with the floor drain structure.

[0039] The implementation principle of the above embodiment is: When the washing machine drainage floor drain core of the present invention is installed in the floor drain structure, the drain pipe of the washing machine needs to be connected and sealed with the guide pipe 11, so that the floor drain has both the functions of floor drainage and washing machine drainage. Specifically, when the floor drain works in a conventional floor drainage mode, the ground sewage naturally flows into the annular water inlet 13 of the core 1 under the action of gravity, and opens the flap 2 along the second drainage channel and flows into the sewage pipe from the second drainage port 15; when the floor drain works in a washing machine drainage mode, the sewage in the washing machine directly enters the guide pipe 11 along the drain pipe of the washing machine and flows into the sewage channel from the first drainage port 14 along the first drainage channel. In addition, the floor drain core of the present invention supports the simultaneous drainage of the ground and the drainage of the washing machine, thereby completely solving the problem of the spread of water on the ground caused by the large amount of water discharged from the washing machine in a short time.

[0040] Example 2

[0041] As attached Figure 9-12 As shown, a floor drain structure disclosed in the present invention includes a floor drain body 4, a mounting base 5, a floor drain cover 6, a switching pipe 7 and the washing machine drainage floor drain core in embodiment 1.

[0042] The floor drain body 4, mounting base 5, and floor drain cover 6 are all conventional. The floor drain body 4 is installed on the ground and connected to the sewage pipe. The mounting base 5 is equipped with a floor drain core, which is then installed into the floor drain body 4 so that the floor drain core extends into the sewage pipe. The mounting base 5 is screwed to the floor drain body 4 to achieve a fixed connection. The floor drain cover 6 is a circular sheet structure that covers the floor drain body 4. It is equipped with a filter to reduce the frequency of solid waste from the ground flowing into the floor drain and causing blockage.

[0043] The inner wall of the mounting base 5 is provided with two L-shaped mounting grooves 51, and the outer wall of the core 1 is provided with two mounting blocks 17 corresponding to the mounting grooves 51. The mounting blocks 17 are elongated protrusions, and their length direction is tilted in the horizontal direction. To facilitate the installation of the core 1 in the mounting base 5, the core 1 is also provided with two indicator arrows corresponding to the positions of the mounting blocks 17. During actual installation, after aligning the indicator arrows on the core 1 with the vertical openings of the mounting grooves 51 on the mounting base 5, the core 1 is pressed downward, and the two mounting blocks 17 immediately enter their corresponding mounting grooves 51. Then, the core 1 is rotated along its axis, causing the mounting blocks 17 to slide within the mounting grooves 51, ultimately securing the core 1 in the mounting base 5. To enhance the sealing effect between the core 1 and the mounting base 5, a rubber sealing ring can be fitted over the sealing ring 16 on the core 1.

[0044] One end of the adapter tube 7 is equipped with a stepped plug, which is fitted with a rubber seal to securely connect to the washing machine's drain pipe and provide a sealed connection. The other end of the adapter tube 7 is equipped with a connector 71 with a threaded outer wall. A circular retaining ring 72 is horizontally mounted on the outer wall of the adapter tube 7, directly above the connector 71.

[0045] A circular through hole 61 is provided at the center of the floor drain cover 6. The diameter of the connecting head 71 is smaller than the diameter of the through hole 61 and the diameter of the fixing clamp 72 is larger than the diameter of the through hole 61, so that the connecting head 71 on the transfer tube 7 can pass through the through hole 61 and only the connecting head 71 can pass through the through hole 61.

[0046] The adapter tube 7 also includes a fixing ring 73. This ring is located below the floor drain cover 6 and has a diameter greater than that of the through hole 61. The inner wall of the fixing ring 73 is threaded. After the connector 71 passes through the through hole 61, the fixing ring 73 engages with the connector 71 and is tightened, thereby securing the connector 71 to the floor drain cover 6.

[0047] The inner diameter of connector 71 is larger than the outer diameter of drainage tube 11. When drain cover 6 is installed on drain body 4, drainage tube 11 fits snugly into connector 71 of adapter tube 7. To enhance the seal between adapter tube 7 and drainage tube 11, a cylindrical sealing sleeve 74 is sleeved within connector 71 of adapter tube 7. Sealing sleeve 74 can be made of a flexible rubber material, with an outer diameter slightly larger than the inner diameter of connector 71 and slightly smaller than the outer diameter of drainage tube 11. This seals the connection between drainage tube 11 and connector 71, preventing odor-causing flies from the sewage pipe from entering the room through this connection.

[0048] The adapter pipe 7 is connected to the drain pipe of the washing machine. Those skilled in the art will appreciate that the drain pipe of the washing machine is only opened and connected to the washing machine when the washing machine is draining water, so odors in the sewage pipe cannot enter the room through the drain pipe of the washing machine. The floor drain structure in this embodiment includes two independent drainage channels. The first drainage channel is dedicated to washing machine drainage and is isolated and sealed from the indoor environment by the drain pipe of the washing machine; the second drainage channel is dedicated to ground drainage and is isolated and sealed from the indoor environment by the flap 2. The two drainage channels can drain water separately or simultaneously while being isolated from the indoor environment, and the drainage functions do not affect each other.

[0049] Although preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they are aware of the basic inventive concepts. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the invention. Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the invention. Thus, the present invention is intended to include such changes and modifications as fall within the scope of the claims and their equivalents.
