[0002] At present, in order to improve the siphon effect of the closestool, the injection hole is usually configured to be directed to the sewage outlet at the bottom of the bowl, and the injection hole is communicated with the water tank through an injection waterway. The common injection waterway extends from the rear end of the bowl to the front end of the outer lateral surface of the bowl, so that the injection waterway is relatively long, and a large amount of air is stored in the injection waterway. When flushing, the air can only be discharged together with the injection hole, and the air bubbles formed by the air move obliquely upward after being discharged from the injection hole. The air bubbles cannot flush the accumulated sewage in the sewage outlet into the sewage pipeline, resulting in a decrease in flushing performance and making the closestool unable to be used normally. SUMMARY

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme.

[0005] A closestool comprises a ceramic body, the ceramic body is provided with a bowl and a siphon pipeline connected to a sewage outlet at the bottom of the bowl, and the closestool is characterized in that it further comprises an injection waterway, a water outlet end of the injection waterway constitutes an injection water outlet, the injection water outlet is communicated with a rising section of the siphon pipeline, the water outlet direction of the injection water outlet tends to be the same as the sewage discharge direction of the rising section, and the injection water outlet is arranged above the rising section of the siphon pipeline.

[0008] Further, the included angle between the water outlet direction of the injection water outlet and the sewage discharge direction of the rising section of the siphon pipeline ranges from 15 degrees to 45 degrees.

[0009] Further, the water passing cross-sectional area of the injection waterway gradually decreases along the water outlet direction.

[0010] Further, the rising section of the siphon pipeline is provided with an accumulation point, and the accumulation point is lower than the sewage outlet.

[0011] Further, the closestool further comprises a flushing ring waterway, the bowl is provided with a flushing ring water outlet at the top, the flushing ring waterway is communicated with the water tank and the flushing ring water outlet, and the flushing ring waterway is further communicated with the injection waterway.

[0012] Furthermore, the toilet bowl is equipped with a brush ring water channel at the top, with the brush ring outlet facing the brush ring water channel, and there is a step difference between the lower end of the brush ring water channel and the upper end of the toilet bowl.

[0013] Furthermore, the jet water path and the brush ring water path are connected to the water tank.

[0014] Furthermore, the front surface of the toilet bowl is provided with an outwardly recessed buffer zone, which extends from the front of the toilet bowl along the left and right sides of the toilet bowl to the rear of the toilet bowl, and the degree of recess of the buffer zone gradually decreases during the extension process.

[0018] 3. The toilet proposed in this utility model has a jet outlet located below the water seal, which reduces the air content in the jet water path. When water is discharged, it can also drive the water source below the water seal to have upward kinetic energy, and form a flowing water slope in the latter half of the rising section of the siphon pipe, thereby improving the siphon effect.

Detailed Implementation

[0031] The following is combined Figures 1-6 This utility model will be described in detail.

[0032] A toilet includes a ceramic body, a bowl 10 and a siphon pipe 20 connected to a drain outlet 101 at the bottom of the bowl 10, and a jet water path 30. The outlet end of the jet water path 30 forms a jet outlet 301, which is connected to the rising section of the siphon pipe 20. The water outlet direction of the outlet end of the jet water path 30 is similar to the drain direction of the rising section, and the jet outlet 301 is located above the rising section of the siphon pipe 20.

[0033] Therefore, in this embodiment, the jet water path 30 is set at the angle between the toilet bowl 10 and the siphon pipe 20 to maximize the use of space, shorten the length of the jet water path 30, reduce the space for air accumulation, and reduce the content of air bubbles when the jet water is flushed. This solves the problem in the prior art that the jet water path 30 extends along the outer surface of the toilet bowl 10, resulting in a long travel distance and a large amount of air accumulation. At the same time, the water outlet direction of the jet water path 30 tends to be the same as the sewage discharge direction of the rising section of the siphon pipe 20, which helps to generate a siphon effect in the siphon pipe 20.

[0034] In this embodiment, as Figure 3 As shown, the water jet channel 30 is located within the ceramic body and at the rear of the drain outlet 101. During the production process, once the ceramic body is formed, the water jet channel 30 is naturally formed within the ceramic body, avoiding the need for additional external connecting pipes and reducing production costs.

[0035] In this embodiment, as Figure 3 As shown, the jet outlet 301 is located below the water seal 80, thereby reducing the air content in the jet water path 30. When the water is discharged, it can also drive the water source below the water seal 80 to have the kinetic energy to flow upward, and form a flowing water slope in the latter half of the rising section of the siphon pipe 20, thereby improving the siphon effect.

[0036] In this embodiment, the angle α between the water outlet direction of the jet outlet 301 and the sewage discharge direction of the rising section of the siphon pipe 20 ranges from 15 degrees to 45 degrees. An angle that is too large or too small will affect the flushing effect. If the angle is too large, the jet water will hit the inner wall of the rising section of the siphon pipe 20, causing the water flow to bounce and spin. If the angle is too small, the sewage outlet 101 of the toilet 10 will be too small, affecting the entry of waste into the sewage outlet 101 and making it more prone to blockage. Specifically, the value of the angle α is 26 degrees. Figure 6 As shown.

[0037] In this embodiment, the cross-sectional area of ​​the jet water path 30 gradually decreases along the outlet direction, causing the flow velocity of the jet water to gradually increase during flow, further increasing the flushing water pressure and helping to drive the water source below the water seal 80. At the same time, the cross-sectional area of ​​the water passing from the jet outlet 301 to the siphon pipe 20 gradually widens, thereby generating negative pressure around the outlet end, which facilitates the generation of a siphon effect within the siphon pipe 20.

[0038] In this embodiment, as Figure 2 As shown, the rising section of the siphon pipe 20 is provided with a gathering point 201, which is lower than the drain outlet 101, so that the sewage automatically slides into the siphon pipe 20, avoiding the accumulation of sewage in the drain outlet 101.

[0039] In this embodiment, a brush ring water channel 40 is also included. A brush ring water outlet 401 is provided on the top of the toilet bowl 10. The brush ring water channel 40 is connected to the water tank 70 and the brush ring water outlet 401. The brush ring water channel 40 is also connected to the jet water channel 30, so that the air in the jet water channel 30 can overflow from the brush ring water outlet 401, thereby reducing the air content in the jet water.

[0040] In this embodiment, the top of the toilet bowl 10 is provided with a brush ring water channel 50, the brush ring water outlet 401 faces the brush ring water channel 50, and there is a step difference 60 between the lower end of the brush ring water channel 50 and the upper end of the toilet bowl 10, so that the brush ring water can flow along the step difference 60, and prevent the brush ring water from flowing to the bottom of the toilet bowl 10 too early.

[0041] In this embodiment, a water tank 70 is also included, with a jet water path 30 and a brush ring water path 40 connected to the water tank 70. Furthermore, the jet water path 30 and the brush ring water path 40 share a portion of the water path, allowing water from the water tank 70 to flow into the shared water path before flowing to the jet outlet 301 and the brush ring outlet 401 respectively. Figure 4 As shown. During rinsing, the water jet outlet 301 releases water preferentially over the brush ring outlet 401, allowing air in the water jet path 30 to move upward quickly and be discharged from the brush ring outlet 401, thereby suppressing the generation of air bubbles in the water jet path 30 and optimizing its rinsing effect.

[0042] In this embodiment, as Figure 4 As shown, the front surface of the toilet bowl 10 is provided with an outwardly recessed buffer zone 102. The buffer zone 102 extends from the front of the toilet bowl 10 along the left and right sides of the toilet bowl 10 to the rear of the toilet bowl 10. The degree of recess of the buffer zone 102 gradually decreases during the extension process, so that when the brushing water flows through the front of the toilet bowl 10, it continues to flow forward along its surface, preventing the brushing water from flowing to the bottom of the toilet bowl 10 too early.

[0043] The toilet proposed in this embodiment works as follows:

[0044] Since the jet outlet 301 is closer to the water tank 70 than the brush ring outlet 401, when flushing, the jet outlet 301 will first perform a 1-2 second pre-flushing to reduce the pressure at the rear end of the rising section of the siphon pipe 20, creating negative pressure, which makes the outside air tend to be forced in. At the same time, the jet outlet 301 drives the water source below the water seal 80 to have the kinetic energy to flow upward, and forms a flowing water flow in the internal area of ​​the pipe. Meanwhile, the brush ring water washes the dirt on the surface of the toilet bowl 10 into the bottom of the toilet bowl 10, and the dirt is discharged from the toilet bowl 10 with the flowing water.

[0045] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
