Description

Technical Field

[0001] This utility model relates to the field of balcony drainage pipe technology, and in particular to an integrated balcony drain device. Background Technology

[0002] To make full use of home space, people often place drainage equipment such as washing machines (large and small), laundry basins, and dryers on balconies. These drainage devices usually share a common drain pipe (a pipe pre-buried in the ground). Although existing drainers are equipped with multiple drain pipe joints, they only drain through a single drain chamber, resulting in a single drain outlet. Furthermore, water from the balcony floor flows directly into the drain chamber, causing the outlet of the drainage device to connect with the floor drain outlet on the drainer. When the drainage volume is large, water from the drainage device may overflow onto the balcony floor through the floor drain outlet.

[0003] Therefore, there is an urgent need for an integrated balcony drain system that prevents water from backing up onto the ground. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated balcony drain, which solves the technical problem in the prior art where water from the drainage device overflows onto the balcony floor through the ground drain outlet when the drainage volume is large.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] refer to Figure 1-6 A specific embodiment of this utility model provides an integrated drain for balconies, installed between the drainage device and the floor drain seat 25 on the balcony. It includes an integrated drain body 1, the top of which is connected to the drain pipe of the drainage device. It also includes: The first anti-reverse component is detachably connected at the top to the bottom of the drain integrated body 1. The first anti-reverse component passes through the drain seat 25 and is sealed between the drain seat 25 and the drain seat 25. The floor drain unit is installed at the bottom of the integrated drainage body 1 and on the first anti-backflow component. The floor drain unit is provided with a first inlet and a second inlet. The first inlet is located above the floor drain seat 25, and the second inlet is located on the side wall of the first anti-backflow component and inside the floor drain cavity 26 of the floor drain seat 25. A second anti-backflow component is provided between the second inlet and the first anti-backflow component.

[0021] Although existing drainers have multiple drain pipe joints, they only drain through a single drain chamber, resulting in a single drain outlet. Water from the balcony floor also flows directly into the drain chamber, creating a connection between the drain outlet and the floor drain outlet on the drainer. When the drain volume is large, water from the drainer overflows onto the balcony floor through the floor drain outlet. In this application, the first anti-backflow component primarily functions unidirectionally, preventing water from flowing back into the drain pipe (not shown in the figure) or odors from escaping from the drain pipe. The main function of the floor drain unit is to facilitate the flow of accumulated water from the floor into the first anti-backflow component and then drain it into the drain pipe. The main function of the first inlet is to facilitate the flow of accumulated water from the floor into the floor drain chamber 26 of the floor drain seat 25. The main function of the second inlet is to facilitate the flow of water from the floor drain chamber 26 into the first anti-backflow component and then into the drain pipe. The main function of the second anti-backflow component is to prevent water flowing into the first anti-backflow component through the second inlet from flowing back into the floor drain chamber 26, and also to prevent water discharged from the drainer into the first anti-backflow component from flowing back into the floor drain chamber 26 and onto the floor. Overall, the balcony integrated drainer of this application can satisfy both drainage equipment drainage and ground drainage, and can also prevent backflow of water from the drain pipe to the drainage equipment and the ground, and prevent water from the drainage equipment from flowing to the ground, thus effectively avoiding backflow.

[0022] Further optimization of the scheme: the first anti-reverse component includes a conduit 13 and a drain core 7. The top end of the conduit 13 is detachably connected to the bottom of the drain integrated body 1, and the drain core 7 is detachably connected to the bottom end of the conduit 13. The drain core 7 passes through the drain seat 25.

[0023] refer to Figure 3 Water discharged from the drainage equipment on the balcony enters the integrated drainage unit 1 through the drain pipe, then flows through the conduit 13 and the floor drain core 7 in sequence, and finally flows into the drain pipe. The floor drain core 7 prevents water in the drain pipe from flowing back up. Water flowing back up in the drain pipe is usually caused by pipe blockage, or by excessive drainage volume.

[0024] Further optimization of the scheme: the floor drain unit includes a drain cover 2 and a floor drain channel 16. The drain cover 2 is fitted onto the bottom of the integrated drainage body 1 and abuts against the bottom of the integrated drainage body 1 through a conduit 13. The drain cover 2 is positioned in contact with the edge of the floor drain seat 25 and forms a first inlet between the drain cover 25 and the edge of the floor drain seat 25. The outer wall of the conduit 13 is recessed inward to form the floor drain channel 16, and a main channel 14 is formed inside the conduit 13. The floor drain channel 16 is located inside the floor drain cavity 26 and connects between the first inlet and the top of the floor drain core 7.

[0025] refer to Figure 1-3Normally, the drain seat 25 is installed on the ground and flush with the ground. The hair catcher 2 is located above the drain seat 25 and placed on the edge of the drain seat 25. The main function of the hair catcher 2 is to filter hair and larger impurities in the water. Water on the ground passes through the hair catcher 2 and enters the drain cavity 26. It then flows through the drain channel 16 to the drain core 7 and the drain pipe. The drain core 7 adopts a common magnetic sealing drain structure.

[0026] To further optimize the scheme, the floor drain unit also includes a water-blocking component 4. Several gaps are provided on the side wall of the water-blocking component 4. The water-blocking component 4 is fitted onto the conduit 13 and abuts against the conduit 13 and the floor drain core 7. Water from the balcony floor flows sequentially through the first inlet, the floor drain cavity 26, the gaps on the water-blocking component 4, the floor drain channel 16, and the floor drain core 7.

[0027] refer to Figure 2-3 The water baffle 4 is a hollow cylindrical structure with several gaps on its side wall (not marked in the figure). First, the water baffle 4 is put on the conduit 13 with a gap between it and the conduit 13. After the drain core 7 is tightened to the bottom end of the conduit 13, the water baffle 4 is placed between the conduit 13 and the drain core 7. Water on the ground enters the drain cavity 26 and passes through the gaps on the water baffle 4. It enters the drain channel 16 through the gap between the water baffle 4 and the conduit 13 or directly enters the drain channel 16, and then flows to the drain core 7 and the drain pipe.

[0028] Further optimizing the scheme, the second anti-backflow component includes a water inlet 17 and an anti-backflow valve 15. The water inlet 17 is located at the bottom of the conduit 13 and connects between the floor drain channel 16 and the floor drain core 7. The water inlet 17 and the floor drain channel 16 form a second inlet. The middle end of the anti-backflow valve 15 is rotatably connected to the bottom of the conduit 13. When the first end of the anti-backflow valve 15 covers the water inlet 17 from below, the second end of the anti-backflow valve 15 is located below the conduit 13. When the first end of the anti-backflow valve 15 is removed from the water inlet 17, the second end of the anti-backflow valve 15 extends into the bottom of the conduit 13, i.e., into the main channel 14.

[0029] refer to Figure 3-4 The height of the water inlet 17 is lower than that of the baffle 4. The water in the floor drain cavity 26 first flows into the floor drain channel 16 and then flows into the water outlet 17. Figure 3The anti-backflow valve 15 is in a free state. When the drainage equipment drains water into the drain pipe, the water enters the main body 1 and the main channel 14. After the water comes into contact with the second end of the anti-backflow valve 15, it impacts the second end of the anti-backflow valve 15, pushing the anti-backflow valve 15 to rotate. This causes the first end of the anti-backflow valve 15 to cover the water outlet 17, and the water outlet 17 is blocked by the first end of the anti-backflow valve 15. Even if the water flow in the main channel 14 is too large, it cannot flow into the ground drain channel 16 through the water outlet 17, and thus cannot backflow to the ground. When there is water accumulation on the ground, the drainage equipment is stopped, and the anti-backflow valve 15 automatically returns to the free state. Water on the ground is prioritized to be discharged into the floor drain core 7 and the drain pipe through the ground drain channel 16 and the water outlet 17.

[0030] To further optimize the design, the bottom surface of the hair-blocking cover 2 is provided with several hair-blocking teeth 3, and the first entrance is located between adjacent hair-blocking teeth 3.

[0031] refer to Figure 1-6 Several hair-blocking teeth 3 are arranged circumferentially, and outer and inner layers are arranged radially. The axial length of the hair-blocking teeth 3 of the inner layer is greater than that of the hair-blocking teeth 3 of the outer layer. The hair-blocking teeth 3 of the outer layer contact the top edge of the drain seat 25, and the hair-blocking teeth 3 of the inner layer contact the inner sidewall of the drain cavity 26 radially. By setting two layers of hair-blocking teeth 3, hair and impurities in the water are effectively intercepted.

[0032] Further optimization of the scheme: the first anti-reverse component also includes a drain extension section 6 and a first sealing ring 5. The drain extension section 6 is detachably connected between the conduit 13 and the drain core 7. The first sealing ring 5 is sleeved on the drain extension section 6 and abuts against the outlet of the drain extension section 6 and the drain seat 25.

[0033] refer to Figure 1-3 The main function of setting the drain extension section 6 is to lower the bottom outlet of the drain core 7 below the cement layer under the floor to prevent water from draining into the gap. The first sealing ring 5 is used to adapt to the 40 drain pipe (pipe with an outer diameter of 40mm). When encountering the 50 drain pipe (pipe with an outer diameter of 50mm), the first sealing ring 5 is replaced with the second sealing ring 18. The outer diameter of the second sealing ring 18 is larger than that of the first sealing ring 5, so it can adapt to the 50 drain pipe.

[0034] Further optimization of the scheme also includes T-junction 8, which is connected to one side of the integrated drainage body 1.

[0035] refer to Figure 1-3 The main function of 6 and 8 is to add a drainage joint to the main body of the drainage system 1, so that the main body of the drainage system 1 can connect to more drainage equipment.

[0036] Further optimization of the scheme also includes a first connector 9, a second connector 10, a third connector 11 and a fourth connector 12. The first connector 9 and the second connector 10 are respectively threaded onto the tee 8, and the third connector 11 and the fourth connector 12 are respectively threaded onto the drainage integrated body 1.

[0037] refer to Figure 1-3 6. The first connector 9, the second connector 10, the third connector 11 and the fourth connector 12 can be plastic connectors; the drain pipe of the drainage equipment can be installed on the first connector 9, the second connector 10, the third connector 11 and the fourth connector 12; when the drainage equipment is small, the tee 8 can be removed from the drainage integrated body 1, and the plug 24 can be installed at the position of the tee connection. The plug 24 is threaded onto the drainage integrated body 1.

[0038] Further optimization of the scheme also includes a fourth sealing ring 21, a second sealing cap 22, a third sealing ring 19, and a first sealing cap 20. The fourth sealing ring 21 is fitted onto the second connector 10, the second sealing cap 22 is fitted onto the first connector 9, the third sealing ring 19 is fitted onto the third connector 11, and the first sealing cap 20 is fitted onto the fourth connector 12.

[0039] refer to Figure 5-6 For larger drain pipes, transition rubber rings (including fourth sealing rubber ring 21 and third sealing rubber ring 19) can be installed on the first connector 9, second connector 10, third connector 11 and fourth connector 12. For example, the fourth sealing rubber ring 21 is fitted onto the second connector 10 and the third sealing rubber ring 19 is fitted onto the third connector 11, thereby adapting to the larger drain pipe and achieving a stable and good sealing effect. When the drain pipe size is smaller than the plastic connector, the second sealing cap 22 is fitted onto the first connector 9 and the first sealing cap 20 is fitted onto the fourth connector 12, and through holes 23 are opened on the first sealing cap 20 and the second sealing cap 22 respectively, so that smaller drain pipes can be inserted into the first sealing cap 20 and the second sealing cap 22, and a stable sealing effect can be ensured.
