Description

Technical Field

[0001] The utility model relates to a hidden water supply device for flushing a wall-mounted toilet. Background Art

[0002] There are two main types of wall-mounted sewage toilets, one is a wall-mounted flush toilet, and the other is a wall-mounted siphon toilet. Both are installed on a bracket embedded in the wall.

[0003] The high-position water tank installed on the bracket and hidden in the wall provides a high potential energy water flow for flushing and draining the toilet. Since the water tank is in the wall, if the water tank fails, the damaged wall needs to be repaired and replaced, which is very time-consuming and labor-intensive, and the repair cost is high. For this reason, toilet flushing devices are hidden and installed in the space between the inner side of the ceramic toilet wall and the outer side of the toilet bowl and the sewage siphon on the market; for example, the toilet disclosed in the Chinese utility model patent (CN219825498U) has the following problems:

[0004] (1) The plastic water tank 100 is U-shaped as a whole, and the front U-shaped part is the water flow path of the inner cavity on both sides of the water tank. The front U-shaped part occupies the space in front of the bottom of the ceramic toilet, so that the electronic function design cannot be installed in the space in front of the bottom of the ceramic toilet, which is not conducive to the function upgrade of the toilet, such as installing a night light or a foot-operated sensor. In addition, the front U-shaped part of the water tank occupies the installation space of the toilet bottom flush nozzle, and the bottom flush nozzle cannot be installed;

[0005] (2) When a pump and a switching valve are placed outside the water tank, many pipes need to be connected outside the water tank. During assembly, due to the insertion of pipes outside the water tank, it is necessary to add positioning parts to fix the pipes, which occupies a large amount of installation space inside the ceramic toilet, affects the assembly efficiency, and is not conducive to improving the competitiveness of the product.

[0031] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0032] like Figure 1 to Figure 5 As shown, a concealed water supply device for flushing a wall-mounted toilet comprises a water tank 21, a flow path integrator 22 inserted on the top surface of the water tank 21, a brush ring water supply pump 23 responsible for supplying water to a brush ring water nozzle 25, and a bottom flushing water supply pump 24 responsible for supplying water to a bottom flushing nozzle 26; the water supply device 20 is installed in a removable manner in the bottom space 11 of the wall-mounted toilet 10 from bottom to top, the front ends of the cavities 214 on both sides of the water tank 21 are connected, and a water connecting portion 213 connected to the cavities 214 on both sides is provided in the middle position of the water tank 21, a front avoidance portion 211 is formed at the front end of the water tank 21 for giving way to the jet pipe 12 and the bottom flushing nozzle 26, and a rear avoidance portion 212 is formed at the rear end for giving way to the sewage elbow 13 of the wall-mounted toilet 10.

[0033] It is worth noting that Figure 1 , Figure 3 to Figure 5As shown, compared with the water storage method in the prior art in which only the front ends of the cavities 214 on both sides of the water tank 21 are connected, the "A"-shaped water tank 21 structure adopted in the present application not only expands the volume of the entire water tank 21, but also because the water connecting part 213 connects the cavities 214 on the left and right sides, it plays a role in stabilizing the connection, so that the water tank 21 has higher structural strength and better anti-twisting and deformation performance; when the water volume in the water tank 21 increases instantaneously, the water flows through the water connecting part 213 between the middle parts of the cavities 214 on both sides, which stabilizes the water pressure and improves the overall shaking of the water tank 21 due to the impact of the water flow.

[0034] The structures of the various components of the utility model are described below.

[0035] like Figure 1 to Figure 3 As shown, the water tank 21 includes an upper shell 201 and a lower shell 202 that are snap-fitted in position. The upper shell 201 and the lower shell 202 enclose two side cavities 214 and a middle water connecting portion 213. The brush ring water supply pump 23 and the bottom flush water supply pump 24 are installed in one of the cavities 214. The brush ring water supply pump 23 is connected to the flow path manifold 22 through the brush ring water supply port 222 on the flow path manifold 22 to supply water to the brush ring water nozzle 25. The bottom flush water supply pump 24 is connected to the flow path manifold 22 through the bottom flush water supply port 223 on the flow path manifold 22 to supply water to the bottom flush nozzle 26. It should be noted here that the two pumps are installed inside the water tank 21, and only two pipes are required outside the water tank 21, which are used to connect the bottom flush nozzle 26 and the brush ring water nozzle 25, respectively, so that the pipes outside the water tank 21 are few and simple, thereby improving the installation efficiency of the water tank 21 on the wall-mounted toilet 10.

[0036] like Figure 1 and Figure 2 As shown, a vacuum breaker 224 is provided at the upper end of the flow path integrator 22, and a water tank inlet 221 connected to the tap water inlet end by a pipe is provided at the lower end; perforated lugs A are provided on both sides of the lower end of the flow path integrator 22, and a perforated lug 2B is provided on the upper shell 201 of the water tank 21 to be aligned with the perforated lug 1A. The perforated lug 1A and the perforated lug 2B are screwed and fixed to quickly fix the flow path integrator 22 on the top surface of the water tank 21.

[0037] like Figure 1 , Figure 3 to Figure 5 As shown, wing plates 27 that touch the bottom edge of the wall-mounted toilet 10 are fixedly installed on both sides of the lower shell 202 of the water tank 21, and a plurality of anchor holes 271 that are aligned with the screw holes 15 on the bottom edge of the wall-mounted toilet 10 are spaced apart along the length direction of the wing plate 27; the screws are passed through the anchor holes 271 on the wing plate 27 and tightened into the screw holes 15 on the bottom edge of the toilet, so that the water tank 21 can be installed as a whole in the bottom space 11 of the wall-mounted toilet 10.

[0038] Combination Figure 1 to Figure 5, the assembly of the utility model is described below.

[0039] Insert the flow channel manifold 22 into the water tank 21, and tighten the aligned perforated lugs A and B with screws, and fix the flow channel manifold 22 on the top surface of the water tank 21; then connect the brush ring water nozzle 25 to the brush ring water supply port 222 on the flow channel manifold 22, and connect the jet pipe 12 connected to the bottom flushing nozzle 26 from bottom to top around the water tank 21 and connect it to the bottom flushing water supply port 223 on the flow channel manifold 22; then put the water tank 21 as a whole from bottom to top into the bottom space of the wall-mounted toilet 10 11 until the upper wing plate 27 of the water tank 21 is pressed against the bottom edge of the wall-mounted toilet 10. At this time, the jet pipe 12 and the bottom flushing nozzle 26 are located in the front avoidance portion 211 at the front end of the water tank 21, the sewage elbow 13 of the wall-mounted toilet 10 is located in the rear avoidance portion 212 at the rear end of the water tank 21, and the water connecting portion 213 of the water tank 21 is located in the partition portion 14 of the wall-mounted toilet 10. Finally, a screw is passed through the anchor port 271 and tightened in the screw hole 15, so that the water supply device 20 can be installed in the wall-mounted toilet 10 as a whole.
