Description

Technical Field

[0001] This utility model relates to the field of toilet technology, specifically to a water tank structure for a wall-mounted toilet. Background Technology

[0002] Most existing wall-mounted toilets use a concealed, recessed cistern structure. While this type of toilet offers advantages in terms of aesthetics and space saving, its drawbacks are also significant: First, installation typically requires pre-construction of a wall before embedding the iron frame and the cistern at the rear of the toilet. This installation process not only causes irreversible damage to the wall but is also extremely cumbersome, demanding a certain level of expertise from installers and resulting in higher installation costs. Second, because the cistern is concealed within the wall, replacing the cistern and various water fittings (such as the inlet valve) is extremely difficult, leading to time-consuming and labor-intensive repairs later. Third, to minimize damage to the wall, the space reserved for the cistern is relatively small, preventing the cistern from being made very large. This small cistern volume can result in insufficient flushing power from the brush and the main flush function, potentially causing clogging.

[0003] In conclusion, existing toilets still need further improvement to meet actual user needs. Utility Model Content

[0004] This utility model provides a water tank structure for a wall-mounted toilet, which is simple in structure, easy to install, easy to implement, and low in cost. It mainly solves the problems of difficult installation and subsequent repair of existing toilet water tanks. The main technical solution adopted is as follows:

[0006] Preferably, the upper casing tube is configured as an upper plastic tube, the lower casing tube is configured as a lower plastic tube, and the upper plastic tube and the lower plastic tube are connected by heat fusion to form a seal.

[0007] Preferably, the free port of the lower casing tube is formed with a sleeve, and the free port of the upper casing tube is formed with a stepped cylinder. The cross-sectional area of ​​the sleeve is larger than the cross-sectional area of ​​the stepped cylinder. The stepped cylinder is inserted into the sleeve to limit the upper casing tube to be installed on the lower casing tube.

[0008] Preferably, the upper plastic tube is injection molded and the lower plastic tube is blow molded.

[0009] Preferably, the limiting component includes a locking assembly and at least one support rod, wherein the support rod is configured as a straight rod or a bent rod; the two free ends of the support rod are respectively connected to the bottom wall of the toilet body, and are fixed to the lower end of the toilet body by the locking assembly, so that the rod surface of the support rod abuts against the lower tank tube to support the lower tank tube.

[0010] Preferably, there are two support rods, which are arranged in parallel with a gap between them, and the rod surfaces of both rods abut against the bottom of the lower box tube.

[0011] Preferably, the locking assembly is configured as a bolt assembly or a snap-fit ​​assembly, and the support rod is fixedly connected to the bottom wall of the toilet body by the bolt assembly or snap-fit ​​assembly.

[0012] Preferably, the limiting component further includes a plurality of sets of interlocking grooves disposed on the bottom wall of the toilet body, wherein each set of interlocking grooves is disposed opposite to each other on the two bottom walls of the toilet body, and the two free ends of the support rod fall into the interlocking grooves and are fixedly connected to the toilet body.

[0014] Preferably, the capacity of the upper and lower casing pipes is not less than 6L.

[0015] As can be seen from the above description of this utility model, compared with the prior art, this utility model has the following beneficial effects:

[0016] (1) This utility model provides a water tank structure for a wall-mounted toilet. Its structure is simple, easy to install, readily achievable, and low in cost. It primarily solves the problems of existing toilet water tanks being difficult to install and requiring subsequent repairs. The technical solution of this utility model involves the water tank structure being directly installed inside the toilet body from bottom to top, eliminating the need for building a wall to reserve installation space. A limiting component securely connects the water tank body to the toilet body, thus preventing the water tank body from detaching due to excessive internal water weight and effectively fixing the water tank body to prevent... The water tank body shakes on the toilet, causing collision noise and impact damage; secondly, the water tank body is designed as a split upper tank pipe and a lower tank pipe, which are distributed vertically. The upper tank pipe is located behind the bowl of the toilet body, while the lower tank pipe adopts a U-shaped design and is laid flat at the lower end of the bowl of the toilet body. This reasonable arrangement of the two not only makes great use of the internal space of the toilet body, but also ensures the water tank's water storage capacity, so as to provide enough water to form a large enough flushing potential energy for a certain period of continuous flushing.

[0017] (2) In this technical solution, the lower box pipe and the upper box pipe are installed by sleeve and stepped cylinder, which can effectively pre-align the lower box pipe and the upper box pipe in advance, so as to ensure that after the lower box pipe and the upper box pipe are heat-fused into one, there will be no misalignment gap between them, which will lead to sealing defects.

[0018] (3) In this technical solution, there are two support rods. The support area of ​​the water tank body can be expanded by the two support rods, which can effectively prevent the water tank body from tilting or shaking at the bottom of the toilet body, so as to avoid impacting the toilet body. The overall structure is more robust.

[0019] (4) In this technical solution, the connection groove can effectively provide a pre-position for the installation of the two free ends of the support rod, and expand the contact area between the support rod and the bottom wall of the toilet body, making the support rod more secure.

[0020] (5) In this technical solution, the side water outlet and the upper tank pipe 21 are set separately, that is, the side water outlet is detachably set on the water inlet of the upper tank pipe 21. Thus, the upper tank pipe 21, the lower tank pipe 22 and the side water outlet are all separate structures of the tank body. In actual assembly, it is easier to install each structure separately inside the toilet body to avoid the difficulty of installation due to the small internal space of the toilet body, and the installation is simpler.

[0033] Please see Figures 1 to 5 .

[0034] This embodiment provides a water tank structure for a wall-mounted toilet. Its structure is simple, easy to install, readily achievable, and low in cost. It primarily addresses the problems of difficult installation and subsequent repairs of existing toilet water tanks. This water tank structure is mainly used in wall-mounted toilets, similar to existing wall-mounted concealed water tanks. The main difference lies in the fact that existing toilets have various structural components such as a main control panel, inlet valve assembly 4, water pump 5, and a drain pipe at the bottom of the toilet. The main control panel and drain pipe, in particular, are quite large. To maximize space, traditional toilet designs often compress the internal space, resulting in very limited utilization of this limited space. Consequently, the toilet tank is typically installed within the wall. This invention, however, improves space utilization through a rational structural layout, allowing the tank to be installed inside the toilet body 1. The tank structure primarily comprises a tank body 2, an inlet valve assembly 4, a water pump 5, and a limiting assembly 3, all mounted on the tank body 2.

[0035] The water tank body 2 is installed inside the toilet body 1 from bottom to top. The water tank body 2 mainly includes a split upper tank pipe 21 and a lower tank pipe 22, which are distributed vertically. The upper tank pipe 21 is installed vertically behind the bowl 11 of the toilet body 1, and the lower tank pipe 22 is U-shaped and is installed horizontally at the lower end of the bowl 11. The U-shaped structure can just avoid the sewage pipe at the lower end of the toilet. With such reasonable structural design and spatial layout design, the water tank body 2 and the internal space of the toilet body 1 are highly compatible.

[0036] In this embodiment, both the upper tank pipe 21 and the lower tank pipe 22 are made of plastic, i.e., the upper and lower plastic pipes are respectively the upper and lower plastic pipes. When connected as a single unit, they have a water storage capacity of no less than 6L. Since the upper tank pipe 21 is installed vertically, it can be formed using injection molding. However, the drain pipe has a U-shaped structure and needs to be laid flat around the perimeter of the toilet's drain pipe, making injection molding difficult. Therefore, it is mainly formed using blow molding. Thus, in this embodiment, using a hot-melt connection between the two plastic materials results in a stronger bond without damaging the original structure. Conversely, using other methods such as bolt connections would require drilling, which could lead to cracks in the upper tank pipe 21 and the lower tank pipe 22. Therefore, a hot-melt connection is the best way to achieve a sealed connection. In other embodiments, the upper plastic pipe can also be formed using blow molding.

[0037] In this utility model, after the upper tank pipe 21 and the lower tank pipe 22 are installed inside the toilet body 1 from bottom to top, in order to prevent the upper tank pipe 21 and the lower tank pipe 22 from falling off on their own due to their heavy weight after water storage, a limiting component 3 is used to fix the water tank body 2 and the toilet body 1 together, thus effectively restricting the water tank body 2 from moving downward.

[0038] In this embodiment, the side wall of the upper tank pipe 21 is provided with a side water outlet 211 facing the pot surface 11. The side water outlet 211 is placed on the overflow groove 12 of the toilet body 1. Thus, if the water inside the upper tank pipe 21 and the lower tank pipe 22 is full, it can be directly discharged to the pot surface 11 through the overflow groove 12.

[0039] In this embodiment, a sleeve 221 is formed at the free port of the lower housing tube 22, and a stepped cylinder 212 is formed at the free port of the upper housing tube 21. The cross-sectional area of ​​the sleeve 221 is larger than that of the stepped cylinder 212. Thus, when the upper housing tube 21 is heat-fused to the lower housing tube 22, the stepped cylinder 212 is first inserted into the sleeve 221 to limit the upper housing tube 21 to be installed on the lower housing tube 22. Thus, after the heat fusion is completed, it is not easy for a sealing leak to occur between the two.

[0040] In this embodiment, the limiting component 3 includes a locking assembly 31 and at least one support rod 32. The two free ends of the support rod 32 are respectively connected to the bottom wall of the toilet body 1 and fixed to the lower end of the toilet body 1 by the locking assembly, so that the rod surface of the support rod 32 abuts against the lower tank tube 22 to support the lower tank tube 22.

[0041] In this embodiment, since the lower casing pipe 22 is U-shaped and laid flat, the area of ​​the entire pipe wall of the lower casing pipe 22 acting on the horizontal plane is relatively large. Although a single support rod 32 can support the entire lower casing pipe 22, the support may be unstable. Therefore, two support rods 32 are provided. The two support rods 32 are set in parallel with a gap, and the rod surfaces of both act to abut against the lower casing pipe 22. In this way, the lower casing pipe 22 wall can be sufficiently supported and will not tilt or shake. In other embodiments, the number of support rods 32 can also be increased, but the structure of double support rods 32 saves more materials and has higher installation efficiency.

[0042] In this embodiment, the two support rods 32 can be configured as straight rods or bent rods with a certain concave angle. For example, in this embodiment, one support rod 32 is a straight rod, which can directly abut against the bottom wall of the U-shaped lower box pipe 22; the other support rod 32 is a bent rod, and the concave bend of the bent rod is just enough to avoid the sewage pipe, while the unbent straight part is in contact with and abuts against the bottom wall of the U-shaped lower box pipe 22; thus, the design of the two support rods 32 provides more stable support for the lower box pipe 22, and the box will not fall due to its own weight, and the bent rod can also effectively avoid the sewage pipe.

[0043] In this embodiment, the locking assembly 31 is configured as either a bolt assembly or a snap-fit ​​assembly. When it is a snap-fit ​​assembly (not shown), a snap-fit ​​is provided on the support rod 32, and a latch is provided on both sides of the bottom wall of the toilet body 1. When the support rod 32 is placed on the bottom wall of the toilet body 1, it is fastened by the snap-fit ​​and the latch, which allows for quick assembly and disassembly. However, this method is costly. In this embodiment, the bolt assembly is mainly used as an example. Threaded holes are opened on both sides of the bottom wall of the toilet body 1, and through holes are opened on the support rod 32. When the support rod 32 is placed on the bottom wall of the toilet body 1, the bolt passes through the through hole of the support rod 32 and is screwed into the threaded hole to fix the support rod 32 to the bottom wall of the toilet body 1.

[0044] In this embodiment, the limiting component 3 also includes several sets of connecting grooves 13 disposed on the bottom wall of the toilet body 1. Each set of connecting grooves 13 is disposed opposite to each other on the two bottom walls of the toilet body 1, that is, each set of connecting grooves 13 has two grooves, and each pair of connecting grooves 13 is disposed opposite to each other. Threaded holes are disposed in the connecting grooves 13. In this embodiment, there are two sets of connecting grooves 13 to accommodate two support rods 32. When the support rods 32 are installed, the two free ends are first pre-positioned in the connecting grooves 13, and then screwed together.

[0045] In this embodiment, the groove depth of the connecting groove 13 is a pre-designed depth. That is, when the support rod 32 is screwed into the connecting groove 13, the support rod 32 acts on the bottom wall of the lower casing pipe 22, causing the top wall of the lower casing pipe 22 to abut against the toilet body 1, thus preventing the lower casing pipe 22 from wobbling. Therefore, by setting the groove depth, the contact area between the support rod 32 and the bottom wall of the lower casing pipe 22 can be increased.

[0046] In this embodiment, the side water outlet 211 and the upper tank pipe 21 are separately configured, and the side water outlet 211 is configured as a water guide channel. The side wall edge of the upper tank pipe 21 extends outward to form a water guide port 14, and the water guide channel is connected to the water guide port 14 through a silicone sleeve (not shown). That is, the side water outlet 211 is detachably set on the water guide port 14 of the upper tank pipe 21. Thus, the upper tank pipe 21, the lower tank pipe 22 and the side water outlet 211 are all separate structures of the tank body. In actual assembly, it is easier to install each structure separately inside the toilet body 1 to avoid the difficulty of installation due to the small internal space of the toilet body 1. Conversely, if the side water outlet 211 and the upper tank pipe 21 are integrated, and the upper tank pipe 21 and the lower tank pipe 22 are heat-fused together, the upper tank pipe 21 is difficult to be directly installed behind the toilet body 1 bowl 11 (or it may be because the side water outlet 211 is too large to be installed directly), and collisions are inevitable during the installation process.

[0047] Working principle and usage process of this utility model:

[0048] During installation,

[0049] First, the stepped cylinder 212 of the upper box tube 21 and the sleeve 221 of the lower box tube 22 are inserted and connected relative to each other, and the hot-melt connection is completed by the existing hot-melt process. At this time, the upper box tube 21 will be located above the lower box tube 22.

[0050] Second, the upper tank pipe 21 and the lower tank pipe 22, which are connected as a whole, are installed inside the toilet body 1. The upper tank pipe 21 is erected behind the pot surface 11 of the toilet body 1, and the water guide 14 on the side wall edge of the upper tank pipe 21 is aligned with the overflow groove 12 of the toilet body 1. The lower tank pipe 22 is laid flat at the lower end of the pot surface 11 and is arranged to avoid the sewage pipe of the toilet body 1.

[0051] Third, the water guide trough is connected to the water guide port 14 through a silicone sleeve (not shown in the figure), so that the upper tank pipe 21 and the lower tank pipe 22 can be easily installed into the toilet body 1.

[0052] Fourth, the inlet valve assembly 4 can be installed in the upper tank pipe 21, and the water pump 5 can be connected to the lower tank pipe 22 via a flexible hose.

[0053] Fifth, the two support rods 32 are pre-fixed by installing them into the two connecting grooves 13 of the toilet body 1, and then the support rods 32 are fixed by bolting them into the threaded holes in the connecting grooves 13. At this time, the upper tank pipe 21 and the lower tank pipe 22 will be supported and limited by the force and will not fall downwards towards the toilet body 1. After that, the control unit (control base and control panel) and the drain component (large single hole drain, water flow through the brush ring to rinse the pot surface) of the toilet can be installed on the toilet body 1. Finally, the entire toilet can be installed on the wall for wall mounting. When disassembly and repair are required later, only the bolts on the two support rods 32 need to be removed, and the water tank body 2 can be completely removed, which is very efficient. Therefore, in this utility model, the water tank structure is directly installed inside the toilet body 1 from bottom to top, eliminating the need to build a wall to reserve space for the water tank installation. The water tank body 2 is fixedly connected to the toilet body 1 by the limiting component 3, which can prevent the water tank body 2 from falling off due to excessive weight of the water stored inside, and effectively fix the water tank body 2 to prevent it from shaking on the toilet and causing collision noise and impact damage. Secondly, the water tank body 2 is designed as an upper tank pipe 21 and a lower tank pipe 22, which are distributed vertically. The upper tank pipe 21 is positioned behind the bowl 11 of the toilet body 1, while the lower tank pipe 22 adopts a U-shaped design and is laid flat at the lower end of the bowl 11 of the toilet. This reasonable arrangement of the two not only makes great use of the internal space of the toilet body 1, but also ensures the water tank's water storage capacity to provide enough water to form a large enough flushing potential energy for continuous flushing for a certain period of time.

[0054] The foregoing description of the specifications and embodiments is intended to explain the scope of protection of this utility model, but does not constitute a limitation on the scope of protection of this utility model. Modifications, equivalent substitutions, or other improvements to the embodiments of this utility model or a portion thereof that can be obtained by those skilled in the art through logical analysis, reasoning, or limited experimentation, based on the teachings of this utility model or the foregoing embodiments, should all be included within the scope of protection of this utility model.
