Description

Technical Field

[0001] The utility model relates to a siphon flush toilet with smooth drainage. Background Art

[0002] The floor-standing siphonic toilet is installed on the floor, and the sewage outlet of the toilet is connected to the sewage outlet on the floor through a sealing flange.

[0003] For example, a toilet disclosed in a Chinese utility model patent (CN2108060620U) has a toilet body 10 in which the wall surface of the toilet bowl 1 decreases in volume from the upper front to the lower rear to form two step surfaces. The bottom of the toilet bowl 1 is a sewage collecting trough. The upper sewage inlet of the sewage pipe 2 of the toilet is connected to the rear of the sewage collecting trough. A jet flushing port is provided on the front wall of the sewage collecting trough to push the sewage into the sewage pipe 2 in a sewage flushing and pressure-gathering manner, thereby enhancing the pumping force of the siphon sewage discharge of the sewage pipe 2 so as to discharge the water mixed with sewage through the sewage pipe 2 out of the toilet.

[0004] But there are some problems with this toilet:

[0005] (1) The waste excreted by the human body is blocked by the step surface. Once the waste is sticky, it takes a long time for the waste to slide from the toilet wall to the sewage collection tank. Some of the waste may not even fall into the sewage collection tank. After the low-pressure flushing siphon sewage discharge of the toilet is completed, there is a possibility that the waste will stick to the toilet wall;

[0006] (2) The sewage inlet connecting the sewage pipe and the sewage collection tank is basically square. This square sewage inlet sometimes blocks the entry of sewage, causing the sewage to be blocked;

[0007] (3) The flushing jet port for auxiliary siphon drainage is outside the sewage inlet of the sewage pipe 2, and is separated from the sewage inlet of the sewage pipe 2 by a sewage collection tank. This method of first pressing the sewage into the sewage inlet and then pressing the sewage inlet of the sewage pipe 2 through the accumulated water in the sewage collection tank will cause a large pressure loss, and more water flow is needed to press, resulting in a longer time spent on auxiliary triggering of the siphon, a greater waste of water resources, and the water efficiency of the toilet flushing water cannot meet the national standards;

[0008] (4) The jet port in the sewage collection tank is higher than the bottom of the tank. The jet of water may even press the paper that has sunk to the bottom under the jet, causing the sewage to be incompletely cleaned. Utility Model Content

[0009] The utility model provides a siphon flush toilet with smooth drainage, which can effectively solve the above problems.

[0010] The utility model is achieved in this way:

[0011] A siphon flush toilet with smooth drainage, comprising a toilet bowl, a sewage pipe connected to the toilet bowl, and a bottom flushing nozzle for flushing sewage and triggering siphon;

[0012] The arc-shaped drainage wall surface in the toilet bowl is smoothly connected with the sewage inlet of the sewage pipe, so that the sewage in the toilet bowl can slide directly into the sewage pipe located at the lowest point of the toilet bowl without being blocked.

[0013] As a further improvement, the bottom flushing nozzle is installed inside the bottom wall of the sewage inlet of the sewage pipe, and the jet port of the bottom flushing nozzle is located inside the sewage inlet of the sewage pipe.

[0014] As a further improvement, the sewage inlet of the sewage discharge pipe is in the shape of an arc with a wide upper opening and a narrow lower opening.

[0015] As a further improvement, the toilet bowl tapers from top to bottom and smoothly extends into the sewage outlet of the sewage pipe.

[0016] As a further improvement, the relationship among the diameter D1 of the sewage inlet of the sewage discharge pipe, the diameter D2 of the ascending section pipe and the diameter D3 of the descending section pipe is: D1>D2>D3.

[0017] The beneficial effects of the utility model are:

[0018] (1) The present application solves the problem that toilet flushing waste and flushing water can quickly slide down into the sewage inlet of the sewage pipe.

[0019] (2) This application solves the problem that the shape of the sewage inlet may block or delay the entry of sewage into the sewage pipe;

[0020] (3) The present application uses a relatively small amount of water to quickly trigger the siphon of the sewage pipe, thereby quickly pumping dirt and sewage out of the toilet, so that the water consumption for flushing the toilet does not exceed the national standards.

[0031] like Figure 1 to Figure 3 and Figure 6 As shown, a siphon flush toilet with smooth drainage comprises a toilet bowl 12, a sewage pipe 11 connected to the toilet bowl 12, and a bottom flushing nozzle 30 for flushing sewage and triggering siphoning; the arc-shaped drainage wall 101 in the toilet bowl 12 is smoothly connected with the sewage inlet 111 of the sewage pipe 11, so that the sewage in the toilet bowl 12 can slide directly into the sewage pipe 11 located at the lowest point of the toilet bowl 12 without being blocked.

[0032] like Figure 1 , Figure 3 and Figure 5 As shown, the bottom flushing nozzle 30 is built-in and installed at the bottom wall of the sewage inlet 111 of the sewage pipe 11, and the jet port 20 of the bottom flushing nozzle 30 is located in the sewage inlet 111 of the sewage pipe 11; when flushing sewage, the sewage and water flow smoothly slide into the water inlet of the sewage pipe 11 from the drainage wall 101, and the bottom flushing nozzle 30 located on the bottom wall of the sewage inlet 111 emits a high-speed water flow from the jet port 20, which quickly triggers the sewage pipe 11 to produce a strong siphon effect, so that the sewage pipe 11 is pumped to suck the sewage and sewage accumulated in the sewage inlet 111 out of the toilet.

[0033] It is worth noting that Figure 1 , Figure 3 and Figure 5 As shown, since the jet port 20 of the bottom flushing nozzle 30 is arranged opposite to the sewage inlet 111 of the sewage pipe 11, the high-speed water flow ejected by the bottom flushing nozzle 30 will only be ejected toward the sewage pipe 11, which can effectively push all the dirt accumulated at the lowest point of the toilet bowl 12 into the sewage pipe 11, and also avoid the phenomenon of dirt or sewage splashing on the water seal surface of the toilet bowl 12 due to the instantaneous release of high-speed water flow by the bottom flushing nozzle 30.

[0034] In the process of flushing and triggering siphoning, the bottom flushing nozzle 30 of the related art may cause some residual dirt to be stranded and retained on the liquid surface of the toilet bowl 12 due to insufficient water, resulting in incomplete flushing and cleaning of the toilet.

[0035] To solve the above problems, Figure 2 to Figure 4As shown, the present application sets the mouth shape of the sewage inlet 111 of the sewage pipe 11 to an arc-shaped mouth with a wide upper mouth and a narrow lower mouth. With such a design, after the sewage reaches the sewage collecting tank of the toilet bowl 12, since the sewage flushing jet port for auxiliary siphon sewage discharge is in the sewage inlet 111, the bottom flushing nozzle 30 only needs a small amount of water, that is, it can quickly trigger the siphon of the sewage pipe. In this process, the pressure loss of the flushing water flow is small and the time taken to trigger the siphon is short.

[0036] like Figure 1 , Figure 3 and Figure 5 , Figure 6 As shown, the toilet bowl 12 gradually shrinks from top to bottom and smoothly extends into the sewage outlet of the sewage pipe 11. The relationship between the diameter D1 of the sewage inlet 111 of the sewage pipe 11, the diameter D2 of the ascending section pipe 112 and the diameter D3 of the descending section pipe 113 is: D1>D2>D3. With such a design, when water flows through the sewage pipe 11, the Venturi effect is triggered due to the gradual decrease in the flow diameter, thereby increasing the flow rate of the water flow to flush the sewage, so as to achieve the effect of quickly triggering the siphon of the sewage pipe 11 with less water, and quickly discharging the sewage and sewage from the toilet, so that the water efficiency of the toilet meets the national standards when flushing, and also has the performance of easy siphoning and sewage flushing.

[0037] Combination Figure 1 to Figure 6 , the working principle of the utility model is described in detail below.

[0038] During flushing, the flushing water and waste from the toilet bowl flow smoothly into the sewage inlet 111 along the drainage wall 101. Due to the shape of the sewage inlet 111 and the water column ejected from the jet port 20, the sewage pipe 11 is quickly triggered to produce a strong siphon effect, so that the waste accumulated in the sewage inlet 111 is quickly siphoned out of the toilet.

[0039] The above embodiments are only used to illustrate the present invention, not to limit the present invention. A person skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and be defined by the claims.
