Description

Technical Field

[0001] The utility model relates to the technical field of floor drains, in particular to a linear floor drain, a balcony drainage system and a shower room drainage system. Background Art

[0002] Currently, barrier-free threshold-less designs are popular for balcony sliding doors and shower doors. Specifically, users often use linear floor drains flush with the ground. These drains effectively remove water and act as a barrier, replacing traditional threshold structures. However, bathroom and balcony floor drains often present a problem: hair, leaves, and other debris accumulate in the drain outlet, clogging it and requiring regular cleaning. If this accumulation isn't promptly removed, the drain won't drain quickly, significantly reducing its water-blocking effectiveness. This can lead to water accumulation in balconies and showers, which can then spill and soak furniture. Utility Model Content

[0043] Reference below Figures 1 to 8 The invention describes a linear floor drain, a balcony drainage system, and a bathroom drainage system provided according to embodiments of the invention.

[0044] like Figures 1 to 8 As shown, the first embodiment of the present invention provides a linear floor drain 100. The linear floor drain 100 of this embodiment has a first direction, a second direction, and a vertical direction, wherein the first direction, the second direction, and the vertical direction are perpendicular to each other. For a clearer illustration, in this embodiment, it is assumed that the first direction is the left-right direction and the second direction is the front-back direction.

[0045] The linear floor drain 100 of this embodiment includes a bottom trough 110, a floor drain cover 120, a cover-type water immersion sensor 130, and a floor drain filter 140. The bottom trough 110, the floor drain cover 120, and the floor drain filter 140 can be made of stainless steel or aluminum alloy.

[0046] The length of the bottom trough 110 extends along the first direction, the width of the bottom trough 110 extends along the second direction, the bottom trough 110 is hollow inside to form a cavity with an opening, the opening of the cavity is open upward, the length of the cavity extends along the first direction, the width of the cavity extends along the second direction, the bottom wall of the cavity is provided with a drain outlet, and the drain outlet is connected to the sewer. In this embodiment, Figure 1 and Figure 4 As shown in FIG, the cavity is rectangular when viewed along the first direction. Figure 2 As shown, viewed from the top and bottom directions, the bottom trough 110 and the floor drain cover 120 are both rectangular.

[0047] It is understood that the dimensions of the bottom trough 110 can be adjusted based on actual needs and are not specifically limited herein. The number of drain outlets is not limited to one; the drain outlets can be fixedly connected to a drain pipe, through which water within the linear floor drain 100 is drained. The bottom wall of the bottom trough 110 cavity can be provided with multiple drain outlets spaced along the first direction to improve drainage efficiency. The specific number of drain outlets can be determined based on actual usage.

[0048] The floor drain cover 120 is disposed above the bottom trough 110 and covers the opening of the cavity, so that the floor drain cover 120 and the bottom trough 110 together form a floor drain body. The length of the floor drain cover 120 extends along the first direction, and the width of the floor drain cover 120 extends along the second direction. The dimensions of the floor drain cover 120 in the first and second directions are equal to or smaller than the dimensions of the bottom trough 110 in the first and second directions.

[0049] The upper surface of the floor drain cover 120 has drainage holes. The number and shape of the drainage holes are not limited and can be set according to actual needs. Viewed from the top and bottom, the drainage holes can be in the shape of an elongated strip, a circle, a square, or a grid. In this embodiment, the drainage holes are elongated holes, the length of the drainage holes extending along the first direction, and multiple drainage holes are provided and spaced apart along the second direction to form a group of drainage holes. Moreover, the floor drain cover 120 is provided with multiple groups of drainage holes spaced apart along the first direction. This design can increase the drainage area while effectively filtering debris such as hair, ensuring smooth drainage.

[0050] In some embodiments, a plurality of supporting structures 121 are provided at the bottom of the floor drain cover 120, and the plurality of supporting structures 121 are arranged at intervals along a first direction. When viewed along the first direction, the floor drain cover 120 and the supporting structure 121 together form a concave structure that is reversed up and down, and the supporting structure 121 is fixedly connected to the bottom of the floor drain cover 120.

[0051] It is understood that the support structure 121 can be made of a metal material such as stainless steel or aluminum alloy, and the connection between the support structure 121 and the floor drain cover 120 can be screw connection, welding connection, or adhesive connection. The support structure 121 and the floor drain cover 120 can also be an integrally formed structure. In this embodiment, the support structure 121 is a U-shaped structure.

[0052] In some embodiments, both inner sidewalls of the bottom trough 110 extending in the first direction are provided with first support plates 111. The first support plates 111 are fixedly connected to the inner sidewalls, and the upper surfaces of the first support plates 111 contact the lower portion of the support structure 121. The first support plates 111 support the support structure 121, ensuring that the upper surface of the floor drain cover 120 is level with the floor, while also leaving a certain space between the lower surface of the floor drain cover 120 and the bottom of the bottom trough 110. This space is used to buffer water flow and prevent it from overflowing.

[0053] It is understood that the connection between the first support plate 111 and the inner sidewall of the bottom trough 110 can be achieved by welding, screwing, or adhesive connection, etc., which is not limited here. The floor drain cover 120 can directly use gravity to make the support structure 121 directly contact the first support plate 111, thereby supporting the floor drain cover 120. In this embodiment, the first support plate 111 is produced on the inner sidewall of the bottom trough 110 through a bending process, and the first support plate 111 is arranged horizontally.

[0054] The cover-type water immersion sensor 130 is arranged on the floor drain cover 120, and the cover-type water immersion sensor 130 is located on the side of the floor drain cover 120 close to the cavity in the up and down directions. The detection end of the cover-type water immersion sensor 130 is set downward. The cover-type water immersion sensor 130 is configured to generate a detection signal when the water level of the floor drain main body rises to a preset water level.

[0055] In some embodiments, the cover-type water immersion sensor 130 includes a cover 131, a signal transmission line 132, a first metal probe 133 and a second metal probe 134. The cover 131 has a cavity, and the first metal probe 133 and the second metal probe 134 both extend in the up and down directions. Moreover, the first metal probe 133 and the second metal probe 134 are arranged at intervals in the horizontal direction.

[0056] The upper end of the first metal probe 133 and the upper end of the second metal probe 134 are both connected to the cover plate 131, so that the first metal probe 133 and the second metal probe 134 are fixed relative to the cover plate 131. Moreover, the upper end of the first metal probe 133 and the upper end of the second metal probe 134 are both located in the cavity, one end of the signal transmission line 132 is located in the cavity and is electrically connected to the first metal probe 133 and the second metal probe 134, and the other end of the signal transmission line 132 extends horizontally outward from the cavity.

[0057] It can be understood that the first metal probe 133 and the second metal probe 134 are fixed to the lower end of the cover plate 131 by insulating material, the upper part of the first metal probe 133 and the upper part of the second metal probe 134 are embedded in the insulating material, and the space between the first metal probe 133 and the second metal probe 134 is filled with insulating material, so that the first metal probe 133 and the second metal probe 134 will not accidentally touch each other to form a loop when they are not soaked in water, thereby avoiding the generation of false alarm signals and misleading users to clean the unblocked linear floor drain 100.

[0058] It is understandable that the insulating material may be resin glue, rubber, polyethylene and other materials, and the insulating material is fixed to the lower surface of the cover plate 131 by gluing.

[0059] It is understandable that when water simultaneously immerses the first metal probe 133 and the second metal probe 134 , the first metal probe 133 and the second metal probe 134 are connected to form an electrical circuit through the water, and a signal indicating successful connection is transmitted through the signal transmission line 132 .

[0060] In this embodiment, the end of the signal transmission line 132 is connected to a sensor electronic control board 400. The sensor electronic control board 400 converts the connected electrical signal into a control signal and outputs it to a system bus 500 connected to the other end of the sensor electronic control board 400. The other end of the system bus 500 is connected to a smart home system. The smart home system receives the control signal and controls an integrated alarm to issue an alarm signal, thereby reminding the user to clear the clogged linear floor drain 100.

[0061] In some embodiments, second support plates 1211 are provided on opposite surfaces of at least two adjacent support structures 121 along the first direction, and the upper surface of the second support plate 1211 contacts the lower surface of the cover plate 131 .

[0062] It is understood that the second support plate 1211 can be formed by cutting a groove from the surface of the support structure 121, and the cover-type water immersion sensor 130 can be slid along the second support plate 1211 to complete installation, with the lower surface of the cover plate 131 slidingly contacting the upper surface of the second support plate 1211. When the drain cover 120 is provided with two cover-type water immersion sensors 130 along the first direction, two adjacent support structures 121 can be selected to be provided with the second support plates 1211 to install one of the cover-type water immersion sensors 130, and two other adjacent support structures 121 can be selected to be provided with the second support plates 1211 to install the other cover-type water immersion sensor 130.

[0063] It is understood that the second support plate 1211 may not be integral with the support structure 121, but rather a separate component. The second support plate 1211 is fixedly connected to the support structure 121. The connection between the second support plate 1211 and the support structure 121 may be welded or adhesively bonded, which is not limited here. The cover-type water sensor 130 is placed on the second support plate 1211 by gravity, with the lower surface of the cover plate 131 in contact with the upper surface of the second support plate 1211.

[0064] In this embodiment, the second support plate 1211 is L-shaped, and the second support plate 1211 and the floor drain cover 120 located on both sides of the cover-type water immersion sensor 130 jointly form a receiving groove, and the opening of the receiving groove is set to be open to one side in the second direction so that the cover-type water immersion sensor 130 can slide in or out of the receiving groove.

[0065] The floor drain filter 140 covers the drain outlet. The shape of the floor drain filter 140 matches the shape of the drain outlet. If the drain outlet is circular, the floor drain filter 140 is circular when viewed from top to bottom. The floor drain filter 140 is used to filter hair, leaves and other debris from the water flow in the floor drain body to prevent the debris from entering the sewer and causing blockage of the sewer. When the debris on the floor drain filter 140 increases, it will cause blockage of the linear floor drain 100, and the water flow cannot be discharged through the sewer in time, causing the water level in the floor drain body to rise and reach a preset water level. At this time, the cover-type water immersion sensor 130 will send a detection signal and transmit it to an external device such as an alarm system. The external device will then use sound and light signals to remind the user to clean up the debris in the floor drain filter 140 in time, keep the drainage smooth, and prevent the water flow in the floor drain body from overflowing the floor drain cover 120.

[0066] The linear floor drain 100 of this embodiment has the following advantages: a cover-type water immersion sensor 130 is provided in the floor drain body, which is composed of a bottom groove 110 and a floor drain cover 120, to detect whether the floor drain body is clogged. When hair, leaves, or other debris accumulates on the floor drain screen 140 at the drain outlet, the water level rises to a preset level. At this time, the cover-type water immersion sensor 130 generates a detection signal. Upon receiving the signal, an external device issues an alarm, reminding the user to promptly clear the blockage in the linear floor drain 100, ensuring smooth drainage and preventing water accumulation. The linear floor drain 100 can be installed on a balcony or in a shower room, replacing a traditional threshold structure. The linear floor drain 100 can be embedded in the balcony floor or shower room floor, with the upper surface of the linear floor drain 100 being on the same level as the ground, allowing users to enter and exit the balcony or shower room without any obstructions.

[0067] In addition, if Figures 1 to 6 As shown, the first embodiment of the present invention further provides a balcony drainage system 200 , the structure of which includes a balcony sliding door, a balcony floor 210 and the linear floor drain 100 of the above embodiment.

[0068] The balcony sliding door is movable in a first direction, with one side of the balcony sliding door in a second direction facing outdoors, and the other side of the balcony sliding door in the second direction facing indoors. A first mounting groove is provided on the balcony floor 210, located on the side of the balcony sliding door in the second direction. The first mounting groove is open and faces upward. A linear floor drain 100 is located on the outdoor side of the balcony sliding door and is disposed within the first mounting groove. The upper surface of the floor drain cover 120 is flush with the balcony floor 210. The linear floor drain 100 replaces the traditional threshold structure, allowing users to enter and exit the balcony without obstacles. It also simplifies the balcony structure, giving the overall balcony decoration a modern, minimalist style.

[0069] The balcony drainage system 200 also includes a first sliding door frame 240, and balcony doors are respectively provided on both sides of the first sliding door frame 240 along the second direction. At least one balcony door is a balcony sliding door. It can be understood that multiple balcony sliding doors can be provided, and the remaining balcony doors can be fixed doors and fixed on the first sliding door frame 240.

[0070] In some embodiments, the balcony door close to the linear floor drain 100 along the second direction is set as the first balcony door 220, and the balcony door away from the linear floor drain 100 along the second direction is set as the second balcony door 230. The bottom of the first sliding door frame 240 is provided with a first door frame drainage gap 260 and a second door frame drainage gap 270. The first door frame drainage gap 260 and the second door frame drainage gap 270 are connected to each other. The first door frame drainage gap 260 is located between the linear floor drain 100 and the first balcony door 220, and the second door frame drainage gap 270 is located between the first balcony door 220 and the second balcony door 230. A water inlet hole 280 is provided on the side of the linear floor drain 100 close to the balcony door along the second direction, and the first door frame drainage gap 260 is connected to the water inlet hole 280.

[0071] It is understood that the height of the first door frame drainage notch 260 is lower than the height of the second door frame drainage notch 270, and the height of the water inlet 280 is lower than the height of the first door frame drainage notch 260. This arrangement facilitates water flow from the first sliding door frame 240 into the water inlet 280, preventing water from stagnating in the first sliding door frame 240 and causing water accumulation, which could cause a user to slip when passing through the first sliding door frame 240.

[0072] In some embodiments, the first balcony door 220 is a fixed door leaf, and the second balcony door 230 is a movable door leaf. In other embodiments, both the first balcony door 220 and the second balcony door 230 are movable door leaves. Of course, in other embodiments, the first balcony door 220 is a movable door leaf, and the second balcony door 230 is a fixed door leaf.

[0073] It is understandable that the shapes of the first door frame drainage gap 260 and the second door frame drainage gap 270 can be circular or polygonal, and the cross-sectional size of the first door frame drainage gap 260 and the second door frame drainage gap 270 is determined according to the actual water volume and is not limited here.

[0074] In some embodiments, the first sliding door frame 240 is provided with a first wiring area 250 , and the cover-type water immersion sensor 130 is routed in the first wiring area 250 .

[0075] It will be appreciated that the bottom and sides of the first sliding door frame 240 are hollow structures. The interior space of the hollow structure forms a first wiring area 250. The bottom surface is provided with wiring holes. The signal transmission line 132 of the cover-type water immersion sensor 130 extends horizontally from the cavity, then extends upward into the wiring holes, and finally enters the first wiring area 250 for routing. The signal transmission line 132 extends upward along the first wiring area 250. The end of the signal transmission line 132 is connected to the sensor electronic control board 400. The signal generated by the cover-type water immersion sensor 130 reaches the sensor electronic control board 400 through the signal transmission line 132.

[0076] The balcony drainage system 200 includes a linear floor drain 100, which can autonomously detect blockages within the drain body. If debris such as hair or leaves is trapped on the drain filter 140, the drain efficiency of the linear floor drain 100 decreases. High balcony water flow can lead to delayed drainage. When the water level within the drain body rises to a preset level, the cover-type water sensor 130 emits a signal, which is then transmitted via the signal transmission line 132 to the sensor control board 400. The control signal is then converted into a control signal, which is then transmitted via the system bus 500 to the smart home system. This triggers an alarm in the smart home system, prompting the user to promptly clear the blockage in the linear floor drain 100, preventing water from overflowing into the living room and soaking furniture, causing financial losses.

[0077] In addition, if Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 and Figure 8 As shown, the first embodiment of the present invention further provides a shower room drainage system 300 , which includes a shower door 310 , a shower room floor 320 and the linear floor drain 100 of the above embodiment.

[0078] The shower door 310 is configured to move in a first direction. One side of the shower door 310 in the second direction faces the outside, while the other side faces the inside. A second mounting slot is provided on the shower floor 320, with its opening facing upward and located below the shower door 310. The linear floor drain 100 is positioned within the second mounting slot, ensuring that the upper surface of the drain cover 120 is flush with the shower floor 320. This arrangement visually integrates the linear floor drain 100 with the shower floor 320, enhancing the aesthetics of the interior while ensuring unimpeded entry and exit for users, preventing tripping hazards.

[0079] When the linear floor drain 100 in the bathroom drainage system 300 is clogged, the linear floor drain 100 can send a signal to the smart home system, and the smart home system will issue an alarm to remind the user to clean the blockage in the linear floor drain 100 in time to prevent water from overflowing from the bathroom and destroying the dry and wet separation environment of the bathroom.

[0080] In some embodiments, the shower room drainage system 300 also includes a second sliding door frame 330, the shower door 310 is arranged on the second sliding door frame 330, the shower door 310 can move relative to the second sliding door frame 330, the second sliding door frame 330 is provided with a second wiring area 340, and the cover-type water immersion sensor 130 is arranged in the second wiring area 340.

[0081] In some embodiments, a wiring hole is provided at the bottom of the second sliding door frame 330, and the side frames of the second sliding door frame 330 are hollow structures. The space within the hollow structure forms a second wiring area 340. The signal transmission line 132 extends horizontally outward from the cavity of the cover-type water sensor 130, enters the wiring hole at the bottom of the second sliding door frame 330 above, and extends to the second wiring area 340. The signal transmission line 132 then extends upward, allowing the other end of the signal transmission line 132 to be connected to the sensor electronic control board 400. Routing the signal transmission line 132 within the second sliding door frame 330 fully utilizes space, protects the signal transmission line 132, reduces the risk of it being chewed by mice, and is isolated from the water flow in the shower room, preventing short circuits caused by damage to the insulation sleeve of the signal transmission line 132 and water contact with exposed wires.
