Description

Technical Field

[0001] The invention belongs to the technical field of floor drains, and in particular relates to a floor drain assembly for a washing machine. Background Art

[0002] Floor drains are essential components that connect sewer pipes to indoor floors. As a crucial component of the drainage system, their performance directly impacts the quality of the indoor environment and air. They centrally discharge domestic wastewater into the sewer pipe, ensuring a clean and comfortable life.

[0003] In daily life, the water discharged from the washing machine also needs to flow out through the floor drain; however, there are the following problems: 1. The current washing machine drain pipe cannot be tightly connected to the floor drain. The size does not match, or the gap is too large, making the washing machine drain pipe unable to be installed, or there is a large gap that allows odor to return. As a result, odors and even bacteria from the sewer cannot enter the washing machine, resulting in the generation of odors and bacteria inside the washing machine, and preventing sewer odors and bacteria from entering the living room through the gap between the drain pipe and the sewer. 2. Because the water flows too quickly when the washing machine drains, it cannot be drained out of the floor drain in time, causing the washing machine to easily overflow and wet the floor when draining, causing inconvenience to people. 3. Because the washing machine drain pipe is a hose, the bend is irregular and unsightly when it is inserted into the sewer or floor drain. Summary of the Invention

[0004] In view of the above problems existing in the prior art, the present invention provides a floor drain assembly for a washing machine, which improves the sealing performance of the water flow path when the washing machine is draining water and avoids the occurrence of assembly gaps.

[0038] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0039] In the description of the present invention, it should be noted that the terms "inner," "upper," "lower," "left," and "right," etc., indicating directions or positional relationships, are based on the positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] See Figures 1-9 , is an embodiment of the floor drain assembly for a washing machine proposed by the present invention, a floor drain assembly for a washing machine includes a floor drain base groove 1 and a surface cover 2 arranged on the top of the floor drain base groove 1, the surface cover 2 is provided with a filter hole 21 and a through hole connected to the washing machine drain pipe 10; it also includes a first connecting pipe 3 matching the through hole, the first connecting pipe 3 is sealed and fixed at the through hole. The washing machine drain pipe 10 is connected to the through hole by the first connecting pipe 3 being sealed and fixed at the through hole; in this way, the drain pipe 10 does not need to be inserted into the surface cover 2, and the drain pipe 10 is sealed and connected to the first connecting pipe 3, avoiding the assembly gap of the washing machine drain flow path, which is beneficial to improving the sealing of the washing machine drain flow path and avoiding the gap from returning odor or water; and the surface cover 2 is provided with a filter hole 21, and water on the ground can flow into the floor drain assembly through the filter hole, that is, the floor drain assembly can simultaneously drain the washing machine and the ground.

[0041] In the present embodiment, the floor drain assembly further comprises an elbow 4 sealedly connected to the upper end of the first connecting pipe 3, the other end of the elbow 4 being detachably sealed and connected to the drain pipe 10; by providing the elbow 4, firstly, the sealing assembly operation of the drain pipe 10 and the elbow 4 is simple, which is conducive to improving the assembly efficiency of the drain pipe 10; secondly, the drainage water flow is limited to a fixed flow direction by the elbow 4, which is conducive to the smooth flow of the drainage water flow; thirdly, the elbow 4 is a regular right-angle structure, which is conducive to the aesthetic appearance of the floor drain assembly. Preferably, the elbow 4 is detachably connected to the first connecting pipe 3, and after the drain pipe 10 is disassembled, the elbow 4 can also be disassembled without occupying the indoor space on the upper part of the face cover 2.

[0042] In this embodiment, see Figure 4 As shown, the floor drain assembly further includes a submersible pipe 5, which is disposed on the bottom surface of the floor drain trench 1 and extends downward. An axial partition 51 is disposed within the submersible pipe 5, i.e., the partition 51 is parallel to the axis of the submersible pipe 5. The partition 51 divides the space within the submersible pipe 5 into a first drainage channel 52 for washing machine drainage and a second drainage channel 53 for ground drainage. By disposing the submersible pipe 5 on the bottom surface of the floor drain trench 1 and extending downward, the submersible pipe 5 takes up almost no space within the floor drain trench 1, leaving a larger space within the floor drain trench 1 for accommodating water flowing from the ground, effectively preventing untimely ground drainage.

[0043] By dividing the submersible pipe 5 into a first drainage passage 52 and a second drainage passage 53, the washing machine drainage and the floor drainage are respectively passed through different spaces in the submersible pipe 5, thereby avoiding the situation where water flows back through the filter holes 21 on the face cover 2 or the assembly gap when the washing machine is drained with a large water flow; that is, the first drainage passage 52 is connected to the washing machine drain pipe 10, that is, it must be connected to the first connecting pipe 3, so that the washing machine drainage is transported to the submersible pipe 5 and flows downward along the first drainage passage 52. The water flows out from the lower end of the submersible pipe 5, and there will be no water flowing back at the face cover 2; the second drainage passage 53 is directly connected to the outside through the filter holes 21 on the face cover 2.

[0044] In this embodiment, a second connecting pipe 7 is sealed between the first drainage channel 52 and the first connecting pipe 3. The second connecting pipe 7 is a hose. The first drainage channel 52 is connected to the first connecting pipe 3 through the sealed second connecting pipe 7, so that all the drainage from the washing machine drain pipe 10 flows into the first drainage channel 52. Figure 8As shown, a cover 55 for closing the first sewer passage 52 is provided at the upper end of the submersible tube 5, and a nozzle 551 matching the second connecting pipe 7 is provided on the cover 55, and the lower end of the second connecting pipe 7 is sealed and fixed on the nozzle 551; by providing the cover 55 and the nozzle 551, it is beneficial to the sealed connection between the second connecting pipe 7 and the first sewer passage 52, which is beneficial to improving the efficiency of assembling the second connecting pipe 7 and the first sewer passage 52 and increasing the sealing after fixation.

[0045] In this embodiment, see Figure 4 As shown, the floor drain assembly also includes a floor drain core 6 that is sleeved onto the outside of the immersion pipe 5. The lower end of the floor drain core 6 is sealed, and drainage holes 61 are spaced circumferentially in the upper and middle portion of the floor drain core 6. The lower end of the immersion pipe 5 is lower than the location of the drainage holes 61, and there is a certain distance between the lower end of the immersion pipe 5 and the bottom surface 62 of the floor drain core 6. After the floor drain assembly completes drainage, a water seal is formed between the floor drain core 6 and the immersion pipe 5, preventing odors in the sewer pipe 20 from passing through the floor drain assembly. Thus, the washing machine drainage flow path consists of the drain pipe 10, the elbow 4, the first connecting pipe 3, the second connecting pipe 7, the first drainage passage 52 of the immersion pipe 5, and the floor drain core 6. Specifically, the water first flows out of the drain pipe 10, flows through the elbow 4, the first connecting pipe 3, the second connecting pipe 7, and then reaches the first drainage passage 52 of the immersion pipe 5. It then flows out of the lower end of the immersion pipe 5 and into the floor drain core 6. It then flows upward along the space between the floor drain core 6 and the immersion pipe 5, reaches the drainage hole 61, and flows out of the floor drain core 6.

[0046] In this embodiment, a drain outlet connected to the sewer pipe 20 is opened at the bottom of the floor drain base trench 1, and the suitably arranged floor drain core 6 and the diving pipe 5 are sealed and fixed at the drain outlet; in this way, the floor drain core 6 and the diving pipe 5 are both accommodated downwardly in the sewer pipe 20, so that the length design of the floor drain core 6 and the diving pipe 5 is almost unlimited. Increasing the length of the floor drain core 6 and the diving pipe 5 is beneficial to increasing the height of the water seal, and avoiding the situation where the water level in the water seal drops below the lower end of the diving pipe 5 as much as possible, and the optimal length can be selected.

[0047] In this embodiment, see Figure 9 As shown, the upper end of the floor drain core 6 is provided with a first flange portion 63 that is bent outward and extends radially. The first flange portion 63 is sealed on the bottom surface of the floor drain base groove 1, that is, the floor drain core 6 and the floor drain base groove 1 are sealed. The provision of the first flange portion 63 is conducive to the sealing and fixation of the floor drain core 6. Specifically, a first annular seal is provided between the first flange portion 63 and the floor drain base groove 1 to prevent the odor in the sewer pipe 20 from emitting into the room through the gap between the first flange portion 63 and the floor drain base groove 1.

[0048] In this embodiment, see Figure 8As shown, the upper end of the diving pipe 5 is provided with a second flange portion 57 that is bent outward and extends radially. The second flange portion 57 is sealed and superimposed on the top of the first flange portion 63. The provision of the second flange portion 57 is beneficial to the sealing and fixation of the diving pipe 5; and there is no gap between the second flange portion 57 and the first flange portion 63. The odor in the sewer pipe 20 enters the floor drain core 6 through the sewer hole 61, preventing the odor from passing through the gap between the first flange portion 63 and the floor drain base groove 1 and dissipating into the room; at the same time, it prevents foam from overflowing from between the floor drain core 6 and the diving pipe 5 to reach the floor drain base groove 1.

[0049] Regarding the sealing arrangement between the first flange portion 63 and the second flange portion 57, in this embodiment, a second annular seal is provided between the first flange portion 63 and the second flange portion 57. In other embodiments, the first flange portion 63 and the second flange portion 57 may also be sealed by extrusion deformation.

[0050] In this embodiment, see Figure 5 As shown, a one-way valve 54 is provided at the lower end of the submersible tube 5 to seal the second drainage passage 53. This prevents water from rushing out of the first drainage passage 52 of the submersible tube 5 when the washing machine is draining, particularly preventing foam from entering the first drainage passage 52 and preventing overflow. Preferably, the one-way valve 54 is an elastic diaphragm. A downwardly extending fixing portion 56 is provided at the lower end of the submersible tube 5. The fixing portion 56 has a radial fixing hole. The one-way valve 54 is provided with an elastic post 541 that matches the fixing hole. The elastic post 541 is located within the fixing hole, and a plug 542 is provided at the outer end of the elastic post 541 to block the outside of the fixing hole. The opening and closing of the one-way valve 54 is achieved by the elastic deformation of the elastic post 541. During surface drainage, water impacts the one-way valve 54, causing it to open, and the elastic post 541 to elastically deform. This elastic deformation of the elastic post 541 provides a reset force.

[0051] In the present embodiment, after the washing machine drainage or ground drainage flows through the immersion pipe 5, the water flows into the floor drain core 6 and the space between the floor drain core 6 and the immersion pipe 5, then flows through the downhole 61 to the space between the immersion pipe 5 and the sewer pipe 20, and finally flows along the sewer pipe 20; therefore, the radial distance between the sewer pipe 20 and the lower portion of the floor drain core 6 is less than the radial distance between the lower portion of the floor drain core 6 and the lower portion of the immersion pipe 5, preferably, the radial annular area between the sewer pipe 20 and the lower portion of the floor drain core 6 is equal to the radial annular area between the lower portion of the floor drain core 6 and the lower portion of the immersion pipe 5, which is conducive to improving the drainage capacity of the floor drain assembly and avoiding the situation where the water flow is not timely. The circumferential interval between the floor drain core 6 and the immersion pipe 5 is provided with vertical support ribs, which is conducive to increasing the fixation between the floor drain core 6 and the immersion pipe 5 and increasing the structural strength.

[0052] In this embodiment, see Figure 9As shown, the floor drain core 6 includes a core body portion 69 with a bottom seal, a first conical cylinder portion 68 extending upward and outward along the upper end of the core body portion 69, and a first flange portion 63 provided at the upper end of the first conical cylinder portion 68, and the drain hole 61 is opened at the intersection of the core body portion 69 and the first conical cylinder portion 68; by arranging the first conical cylinder portion 68, the upper end of the floor drain core 6 is close to the edge of the bottom drain outlet of the floor drain base trench 1, and the upper end size of the first conical cylinder portion 68 is preferably matched with the drain outlet, and the first flange portion 63 is sealed and fixed on the bottom surface of the floor drain base trench 1 at the edge of the drain outlet; by arranging the drain hole 61 at the intersection of the core body portion 69 and the first conical cylinder portion 68, a water seal can be formed in the area below the drain hole 61 in the floor drain core 6, which is beneficial to increase the height of the water seal and ensure the water seal effect.

[0053] In this embodiment, the submersible pipe 5 also includes a lower submersible body portion 59, a second conical portion 58 extending upward and outward along the upper end of the submersible body portion 59, and a second flange portion 57 provided at the upper end of the second conical portion 58; by providing the second conical portion 58, the upper end of the submersible pipe 5 is close to the edge of the bottom drain outlet of the floor drain base trench 1, and it is preferably provided that the angle between the second conical portion 58 and the axis is smaller than the angle between the first conical portion 68 and the axis, so that there is a certain buffer space between the second conical portion 58 and the first conical portion 68 for water flow buffering.

[0054] As for the sealed connection between the first connecting tube 3 and the through port, in this embodiment, the first connecting tube 3 and the through port are threadedly connected, and a radially extending rib 31 is provided at the lower end of the first connecting tube 3. The rib 31 is stopped below the face cover 2, that is, the connecting tube 3 is installed at the through port from below the face cover 2.

Any person skilled in the art may utilize the technical content disclosed above to make changes or modifications to equivalent embodiments with equivalent variations. However, any simple modifications, equivalent variations, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
