Description

Technical Field

[0001] This invention relates to the field of waterproof bathroom technology, and more specifically, to a secondary drainage chassis, a secondary floor drain, and an integrated bathroom system. Background Technology

[0002] Currently, as people's living standards improve, their demands for quality of life also increase, leading to a desire for more user-friendly products. Bathroom fixtures are widely used in daily life, and since they frequently come into contact with water, they are equipped with waterproof structures and drainage drains.

[0003] Current bathroom fixtures typically have floor drains on the bottom wall for drainage and multi-layered waterproof structures on the side walls. Chinese Patent Publication No. CN207959447U, published on October 12, 2018, discloses a waterproof bathroom base and an integrated bathroom system. The waterproof base includes a main body with drainage holes housing a floor drain and a sewage pipe. The perimeter of the main body is bent upwards to form a flange. During assembly, the waterproof base is processed according to the bathroom's structure and dimensions, placed on the bathroom floor, and reliably connected to the bathroom fixtures. Floor tiles or other decorative materials are then laid on top, and a wall covering is installed. The bottom of the wall covering is located inside the flange. The waterproof base must be made of waterproof material. However, bathrooms have high water flow rates. If water seeps through the wall panels and penetrates the waterproof layer, it is difficult to drain from the wall, causing it to stagnate and breed bacteria and produce odors. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing bathroom fixtures that lack drainage structures designed to prevent water seepage into walls, and to provide a secondary drainage base, a secondary floor drain, and a complete bathroom system. This invention improves the drainage structure of the bathroom, allowing water that seeps into the wall to drain out, preventing water from stagnating inside the wall and breeding bacteria and producing odors.

[0005] The present invention also provides a secondary drainage floor drain and an integrated bathroom.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a secondary drainage chassis, which includes a first component and a second component. One end of the first component is vertically disposed at one end of the second component. The first component is provided with a water collection trough. The top and bottom of the water collection trough are respectively provided with water collection holes and drainage holes. The drainage holes are provided with drainage embedded parts.

[0007] In this technical solution, the second component is vertically connected to the first component, and its cross-section is "L". The second component is located inside the wall at the bottom of the bathroom side wall, and the first component wraps around the end face of the side wall. Water that seeps into the wall will enter the second frame due to its own gravity, enter the water collection tank through the water collection hole on the first component, and then enter the drainage embedded part through the drain hole on the water collection tank for discharge.

[0008] Furthermore, a reinforcing member is provided at the end of the second component away from the first component. The reinforcing member enhances the overall stability of the secondary drainage chassis.

[0009] Furthermore, the reinforcing member is a hollow frame, and the end of the hollow frame away from the first component has a beveled edge on the side facing the first component for guiding water flow. The hollow frame can improve the structural stability of the secondary drainage chassis, and the hollow structural design can reduce the overall weight. The beveled edge on the hollow frame guides the water flow, allowing water that has seeped into the wall to flow along the bevel to the first component, then enter the water collection tank through the water collection hole, and finally be discharged from the drainage embedded part on the drainage hole of the water collection tank.

[0010] Furthermore, the water collection trough is located at the end of the first component closer to the second component. Since the second component guides the water that seeps into the wall to the first component, and then into the water collection trough through the water collection hole, the water collection trough is located at the end of the first component closer to the second component, which can collect the water diverted by the second component in a timely manner and improve the collection efficiency of water seepage in the wall.

[0011] A secondary drainage floor drain includes an inner core, a drain body, and a secondary drainage base. The inner core is embedded in the drain body, which has an inlet pipe and a outlet pipe. The inlet pipe is connected to the pre-embedded drainage component via a pipe. The secondary drainage floor drain has two drainage modes: one is for household wastewater from the bathroom, which flows from the floor into the inner core, then into the drain body and out through the outlet pipe; the other is for water that has seeped into the wall, which enters the pipe through the drain hole in the secondary drainage base, then flows into the drain body via the pipe and the inlet pipe, and finally exits through the outlet pipe. This technical solution allows water seepage from the wall to be drained through the secondary drainage floor drain, preventing bacterial growth and odors caused by long-term water accumulation inside the wall, thus improving the user experience.

[0012] Furthermore, the drain body has a cavity, with the inner core embedded within it. The water inlet pipe is connected to the outer circumferential wall of the cavity and communicates with it. The drain outlet pipe communicates with the top opening of the cavity. The inner core, embedded within the cavity, is not directly connected to the drain outlet pipe. Domestic wastewater from the floor enters the drain body through the inner core, filling the cavity and overflowing from the top opening before draining through the drain outlet pipe. This design creates a water trap between the drain outlet pipe and the inner core, preventing direct communication between the drain outlet pipe and the inner core, thus preventing sewer odors from escaping from the inner core. Seepage collected from the secondary drainage chassis also enters the drain body's cavity through the water inlet pipe, overflows from the top opening of the cavity, and drains through the drain outlet pipe.

[0013] Furthermore, the inner core has a panel on top, and the panel has a removable filter screen. The panel fixes the drain body to the pre-drain hole in the ground. The filter screen can filter impurities or hair in the domestic water, preventing them from entering the inner core and clogging the secondary drainage drain and its connected sewer pipes. The filter screen can be removed from the top of the inner core for easy cleaning.

[0014] Furthermore, the inner core is fixed to the drain body by bolts.

[0015] An integrated bathroom unit includes a bottom wall, side walls, and a secondary drainage floor drain. The floor drain body is fixed to the bottom wall, and the secondary drainage base is located inside the side walls. This integrated bathroom unit can not only drain domestic wastewater from the bathroom space but also drain water that seeps into the side walls, preventing water accumulation on the side walls from causing bacterial growth and odors.

[0016] Furthermore, the sidewall includes a wall body, a wall panel, and a waterproof layer. The waterproof layer is located between the wall body and the wall panel. The second component is located between the waterproof layer and the wall body. The first component covers the bottom end face of the waterproof layer and the wall panel. In this technical solution, the second component guides water that has seeped through the waterproof layer between the wall body and the waterproof layer into the water collection tank of the first component. The water then flows from the water collection tank through a pipe into the drain body for discharge. This allows the water that has seeped through the waterproof layer on the sidewall to be discharged a second time, preventing it from accumulating inside the sidewall for a long time, which could lead to bacterial growth and odor.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention features a secondary drainage tray inside the side wall, which collects and drains water that seeps into the side wall, preventing water from accumulating and causing bacteria growth and odors. The invention also improves the structure of the drain body, allowing water collected by the secondary drainage tray to enter the drain body through the inlet pipe and then drain into the sewer through the drain outlet pipe. Furthermore, the drain body has an internal cavity, with a water trap forming between the sewer and the inner core to prevent sewer odors from escaping into the bathroom. Attached Figure Description

[0025] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0026] In the accompanying drawings of the embodiments of the present invention, the same or similar reference numerals correspond to the same or similar components. In the description of the present invention, it should be understood that if terms such as "upper," "lower," "left," "right," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0027] Example 1

[0028] like Figure 1 The illustration shows an embodiment of a secondary drainage chassis according to the present invention. The secondary drainage chassis has an overall elongated structure, including a first component 1 and a second component 2. One end of the first component 1 is vertically disposed at one end of the second component 2. The entire secondary drainage chassis has an "L"-shaped cross-section, which is used to interlock with the vertical angle of the side and bottom walls of the bathroom fixture. The first component 1 has a water collection trough 101 inside, a water collection hole 102 at the top of the water collection trough 101, and a drainage hole at the bottom of the water collection trough 101. A drainage embedded part 3 is interlocked within the drainage hole.

[0029] The second component 2 is provided with a reinforcing member 201 at the end away from the first component 1. The reinforcing member 201 consists of two parallel hollow frames. While improving the overall strength and stability of this embodiment, the hollow structure reduces the overall weight of the embodiment. The hollow frame is provided with a bevel 202 on the side facing the first component 1. The bevel 202 can guide the water that seeps into the side wall to flow towards the first component 1 and enter the water collection tank 101 from the water collection hole 102 on the first component 1.

[0030] In addition, the water collection tank 101 is located at the end of the first component 1 near the second component 2, so that the water flowing down from the second component 2 can flow directly into the water collection tank 101 from the water collection hole 102 on the first component 1, thus avoiding accumulation on the first component 1.

[0031] Example 2

[0032] like Figure 2 The illustration shows an embodiment of a secondary drainage floor drain according to the present invention. The secondary drainage floor drain includes a drain body 5, an inner core 6, and a secondary drainage chassis mentioned in Embodiment 1. The inner core 6 is embedded inside the drain body 5. An inlet pipe 501 and a drain outlet pipe 503 are connected. A drainage embedded component 3 is connected to the inlet pipe 501 via a pipe 4. The water collection tank 101 of the secondary drainage chassis collects water, which enters the drain body 5 through the pipe 4 and the inlet pipe 501, and then drains into the sewer pipe from the drain outlet pipe 503.

[0033] The drain body 5 has an internal cavity 502, with an inner core 6 embedded within it. A water inlet pipe 501 connects to the circumferential wall of the cavity 502, and a drain outlet pipe 503 connects to the opening at the top of the cavity 502. The inner core 6, embedded within the cavity 502, is not directly connected to the drain outlet pipe 503. Domestic wastewater enters the drain body 5 through the inner core 6, filling the cavity 502 and overflowing from the opening at the top before draining through the drain outlet pipe 503. This design creates a water trap between the drain outlet pipe 503 and the inner core 6, preventing direct connection between the drain outlet pipe 503 and the inner core 6, thus preventing sewer odors from escaping from the inner core 6. Water collected from the secondary drainage chassis also enters the cavity 502 of the drain body 5 through the water inlet pipe 501, overflows from the opening at the top of the cavity 502, and drains through the drain outlet pipe 503.

[0034] In addition, the inner core 6 has a panel 504 on its top, and the panel 504 has a removable filter screen. The filter screen can be set with two layers, which can filter the debris in the domestic water in two layers to prevent it from flowing into the drain body 5 and clogging the entire drainage system. The inner core 6 is fixed to the drain body 5 with bolts.

[0035] The working principle of this embodiment is as follows: This embodiment drains accumulated water from two locations, such as... Figure 4 As shown, one method involves wastewater from the bathroom draining from the floor into the inner core 6, then flowing from the inner core 6 into the drain body 5 and out through the drain outlet pipe 503. The other method involves water seeping into the side wall entering the pipe 4 through the drain hole of the secondary drainage base, then entering the drain body 5 through the inlet pipe 501, and finally being discharged from the drain outlet pipe 503 of the drain body 5. This completes the process of draining water that has seeped into the side wall from the drain body 5, preventing bacteria from growing and causing odors due to long-term water accumulation inside the side wall, which would affect the user experience.

[0036] Example 3

[0037] like Figure 3 The illustration shows an embodiment of a prefabricated bathroom according to the present invention. The prefabricated bathroom includes a bottom wall, side walls, and a secondary drainage floor drain as shown in Embodiment 2. The bottom surface of the prefabricated bathroom is covered with floor tiles 9, with a floor drain hole at one corner. The secondary drainage floor drain is installed in the floor drain hole. The secondary drainage base is located inside the side wall, which includes a wall body 10, a wall panel 7, and a waterproof layer 8. The waterproof layer 8 is located between the wall body 10 and the wall panel 7. A second component 2 is located between the waterproof layer 8 and the wall body 10. A first component 1 wraps around the bottom end faces of the waterproof layer 8 and the wall panel 7. The elongated structure of the secondary drainage base can completely wrap around the side wall of the bathroom.

[0038] like Figure 4 As shown, when water seeps through the waterproof layer 8 from the bathroom side wall, the seeping water is guided by the second component 2 into the water collection tank 101 of the first component 1, and then flows from the pipe 4 into the drain body 5, and from the drain body 5 into the sewer. This embodiment can not only drain domestic water in the bathroom space, but also drain water that seeps into the side wall, avoiding long-term water accumulation in the bathroom side wall, which can breed bacteria and produce odors. Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the claims of the present invention.
