Description

Technical Field

[0001] This utility model relates to the field of sanitary ware technology, and in particular to a toilet. Background Technology

[0002] In a jet siphon toilet, the water in the tank is split into flushing water and jet water through a ceramic channel, ultimately creating a siphon inside the toilet to flush the waste into the drain pipe.

[0003] In existing toilets, the flush bowl is funnel-shaped. The flushing water washes away dirt along the wall of the flush bowl and then drains into the sewer through a siphon channel connected to the bottom of the flush bowl. During the flushing process, when the inflow of flushing water is greater than the outflow of the siphon channel, the water level inside the flush bowl rises. This causes the dirt in the water to spread in the flush bowl with the rising water level, resulting in the dirt not being concentrated during siphoning and thus not being easily discharged from the siphon channel. Furthermore, due to the splitting of the water jet, the flow rate of flushing water is relatively small, only used for washing the flush bowl, and its cleaning ability for the flush bowl wall is insufficient. The flushing time is also short, and it cannot effectively wash away the dirt attached to the flush bowl wall, resulting in a large area of ​​dirt residue. Utility Model Content

[0004] The purpose of this invention is to provide a toilet that can improve the ability to discharge dirt and reduce dirt residue.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] Toilet, including:

[0007] A pot surface tank, comprising a washing chamber and a dirt collection chamber, wherein the inlet of the dirt collection chamber is connected to the bottom of the washing chamber, and the inner wall of the dirt collection chamber is recessed relative to the inner wall of the washing chamber to form an expansion area.

[0008] A siphon channel, the inlet of which is connected to the bottom of the sludge collection chamber, and the highest point of the sludge collection chamber is higher than the highest point of the siphon channel.

[0009] Preferably, the inlet of the dirt-collecting chamber is connected to the rear end of the bottom of the washing chamber, and the front end of the inlet of the dirt-collecting chamber is lower than the rear end.

[0010] Preferably, the bottom of the washing chamber is connected to the front side of the dirt-collecting chamber via a first inclined surface. The first inclined surface gradually decreases in the direction close to the dirt-collecting chamber, and the angle A between the first inclined surface and the horizontal plane ranges from 8° to 20°.

[0011] Preferably, the rear end of the washing chamber is recessed to form a flow-limiting groove.

[0012] Preferably, the inlet of the siphon channel is connected to the rear end of the bottom of the sludge collection bin, and the front end of the inlet of the siphon channel is lower than the rear end.

[0013] Preferably, the bottom of the sludge collection bin is connected to the front side of the siphon channel via a second inclined surface. The second inclined surface gradually decreases in the direction close to the siphon channel, and the angle B between the second inclined surface and the horizontal plane ranges from 12° to 20°.

[0014] Preferably, the height H of the front end of the sludge collection bin is not less than 55mm.

[0015] Preferably, the difference E between the highest point of the sludge collection chamber and the highest point of the siphon channel is in the range of 10mm-40mm.

[0016] Preferably, the pipe diameter at the inlet of the siphon channel is D1, the pipe diameter at the highest point is D2, and the pipe diameter at the outlet is D3, with D1, D2, and D3 decreasing sequentially.

[0018] The beneficial effects of this utility model are:

[0019] The pot surface tank includes a washing chamber and a dirt collection chamber connected from top to bottom. The inner wall of the dirt collection chamber at the bottom is recessed relative to the inner wall of the washing chamber to form an expansion zone. By setting the expansion zone, the lower part of the pot surface tank has a larger capacity than the existing structure, thereby reducing the rise height of the water level in the pot surface tank during rinsing and reducing the area where dirt in the water spreads with the water surface. By setting the dirt collection chamber and setting the highest point of the dirt collection chamber to be higher than the highest point of the siphon channel, the dirt is more concentrated during siphoning, ensuring that the water level rises within the dirt collection chamber. The water surface is located in the dirt collection chamber, making it easier for dirt to be discharged by the siphon channel and reducing dirt residue. Attached Figure Description

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1 to 4As shown, this utility model provides a toilet, including a bowl-shaped sink 1 and a siphon channel 2. The bowl-shaped sink 1 includes a washing chamber 11 and a sludge collection chamber 12. The inlet of the sludge collection chamber 12 is connected to the bottom of the washing chamber 11. The inner wall of the sludge collection chamber 12 is recessed relative to the inner wall of the washing chamber 11 to form an expansion area 121. The inlet of the siphon channel 2 is connected to the bottom of the sludge collection chamber 12, and the highest point of the sludge collection chamber 12 is higher than the highest point of the siphon channel 2.

[0034] In this invention, the pot surface tank 1 includes a washing chamber 11 and a dirt collection chamber 12 connected from top to bottom. The inner wall of the dirt collection chamber 12 at the bottom is recessed relative to the inner wall of the washing chamber 11 to form an expansion area 121. By setting the expansion area 121, the lower part of the pot surface tank 1 has a larger capacity than the existing structure, thereby reducing the rise height of the water level in the pot surface tank 1 during rinsing and reducing the area of ​​dirt spreading with the water surface. By setting the dirt collection chamber 12 and setting the highest point of the dirt collection chamber 12 to be higher than the highest point of the siphon channel 2, the dirt is more concentrated during siphoning, ensuring that the water level rise does not exceed the dirt collection chamber 12. The water surface is located in the dirt collection chamber 12, thereby making it easier for the dirt to be discharged by the siphon channel 2 and reducing dirt residue.

[0035] In this embodiment, the toilet is only provided with a swiping inlet and not a jet inlet, thereby avoiding the diversion of the jet water, increasing the flow rate of the swiping water, enhancing the flushing ability on the wall of the pot sink 1, effectively flushing away dirt attached to the wall of the pot sink 1, and further reducing dirt residue.

[0036] In other embodiments, the toilet may also be provided with a washbasin nozzle and a jet nozzle.

[0037] Figure 3 The Chinese characters indicate the four directions of the toilet: front, back, top, and bottom. In this embodiment, for example... Figure 4 As shown, the inner front wall of the sludge collection chamber 12 is recessed relative to the inner front wall of the washing chamber 11 to form an expansion area 121.

[0038] In other embodiments, the expansion area 121 may also be located on the rear, left, or right side of the sludge collection bin 12.

[0039] In other embodiments, the expansion area 121 may also be located at at least two of the front, rear, left and right sides of the sludge collection bin 12.

[0040] Specifically, the inlet of the sludge collection chamber 12 is connected to the rear end of the bottom of the washing chamber 11, and the front end of the inlet of the sludge collection chamber 12 is lower than the rear end. The connection between the sludge collection chamber 12 and the rear end of the bottom of the washing chamber 11 allows water to flow from front to back into the sludge collection chamber 12. Under the action of inertia, the water flowing into the sludge collection chamber 12 impacts and converges backward. The water surface is higher at the rear end and lower at the front end. The structure of the sludge collection chamber 12 is adapted to this, ensuring the sludge collection effect.

[0041] More specifically, the bottom of the washing chamber 11 is connected to the front side of the dirt collection chamber 12 via a first inclined surface. The first inclined surface gradually decreases in the direction close to the dirt collection chamber 12, and the angle A between the first inclined surface and the horizontal plane ranges from 8° to 20°. This arrangement allows water in the washing chamber 11 to flow smoothly into the dirt collection chamber 12.

[0042] More specifically, a flow-limiting groove 111 is recessed at the rear end of the washing chamber 11. Under the action of inertia, when the water flowing into the dirt collection chamber 12 splashes backward, it can be buffered and limited by the flow-limiting groove 111 to prevent it from splashing out from the opening of the pot surface groove 1.

[0043] In this embodiment, from the front end to the rear end, the first inclined surface gradually descends, and the top surface of the sludge collection bin 12 gradually rises. The angle A between the first inclined surface and the horizontal plane is 13°. The connection between the first inclined surface and the front side wall of the sludge collection bin 12 is rounded to create a smooth transition. The washing ring water outlet is located on the upper side of the flow restriction groove 111, and the washing ring water can flush through the flow restriction groove 111.

[0044] Specifically, the inlet of siphon channel 2 is connected to the rear end of the bottom of the sludge collection bin 12, and the front end of the inlet of siphon channel 2 is lower than the rear end. The connection between the inlet of siphon channel 2 and the rear end of the bottom of the sludge collection bin 12 allows water to flow from front to back into siphon channel 2. Due to inertia, the water flowing into siphon channel 2 impacts and converges backward. The structure of the inlet of siphon channel 2 is adapted to this, ensuring a guiding effect, allowing the water flowing into siphon channel 2 to be guided backward and then discharged into the sewer pipe.

[0045] More specifically, the bottom of the sludge collection tank 12 is connected to the front side of the siphon channel 2 via a second inclined surface. The second inclined surface gradually decreases in the direction close to the siphon channel 2, and the angle B between the second inclined surface and the horizontal plane ranges from 12° to 20°. This arrangement allows the water in the sludge collection tank 12 to flow more smoothly into the siphon channel 2.

[0046] In this embodiment, from the front end to the rear end, the second inclined plane gradually descends, and the inlet end face of the siphon channel 2 gradually rises. The angle B between the second inclined plane and the horizontal plane is 16°. The connection between the second inclined plane and the front end side wall of the siphon channel 2 is rounded to achieve a smooth transition.

[0047] Specifically, the height H of the front end of the sludge collection chamber 12 is not less than 55mm. This setting ensures the depth of the sludge collection chamber 12 and improves the sludge collection effect.

[0048] More specifically, the difference E between the highest point of the sludge collection chamber 12 and the highest point of the siphon channel 2 ranges from 10mm to 40mm. This configuration further ensures that the water level rise does not exceed the sludge collection chamber 12, and the water cover is located in the lower middle part of the sludge collection chamber 12.

[0049] More specifically, the length L of the sludge collection bin 12 ranges from 150mm to 200mm, and / or the width W of the sludge collection bin 12 ranges from 120mm to 150mm. The above settings ensure the volume of the sludge collection bin 12.

[0050] In this embodiment, the length L of the sludge collection bin 12 ranges from 150mm to 200mm, and the width W of the sludge collection bin 12 ranges from 120mm to 150mm.

[0051] Specifically, the inlet of the siphon channel 2 is connected to the rear end of the bottom of the sludge collection bin 12, and the outlet is connected to the sewer pipe. The pipe diameter at the inlet of the siphon channel 2 is D1, the pipe diameter at the highest point is D2, and the pipe diameter at the outlet is D3, with D1, D2, and D3 decreasing sequentially. This configuration ensures that the siphon channel 2 has a narrowing diameter, allowing it to quickly fill the pipe and form a siphon during flushing.

[0052] In this embodiment, the pipe diameter D1 at the inlet of the siphon channel 2 is 70mm, the pipe diameter D2 at the highest point is 55mm, and the pipe diameter D3 at the outlet is 45mm.

[0053] In this embodiment of the toilet, the lower spray nozzle is eliminated, and all water flows out through the wash ring nozzle, thereby enhancing the washing effect on the toilet wall. The siphon channel 2 of the toilet can perform siphoning. The water flow causes the water level in the sink 1 to rise, forming a full pipe of water inside the siphon channel 2 and creating a height difference, thereby forming a siphon to carry away the dirt.

[0054] To ensure that the siphon channel 2 is full, the inflow of the washing ring water must be greater than the outflow of the siphon channel 2, creating a flow difference between the two ends, which ultimately makes the siphon channel 2 full.

[0055] If the inlet water flow of the washing ring is greater than the outlet water flow of the siphon channel 2, the water level inside the pot surface tank 1 will rise, and the dirt in the water will also rise and spread. If the traditional funnel-shaped pot surface is still used, the water level will rise and the surface area of ​​the water will spread more, so the dirt will also spread at the same time. During siphoning, the dirt will not be concentrated and will not be easily discharged.

[0056] In this embodiment, the water flows out from the washing ring water outlet, and the water flow has sufficient scrubbing force on the wall of the pot surface 1. The slope of the pot surface of the washing chamber 11 can be reduced. The pot surface of the washing chamber 11 is raised, the slope is reduced, and a dirt collection chamber 12 is set between the washing chamber 11 and the siphon channel 2. The bottom surface of the washing chamber 11 is connected to the dirt collection chamber 12 through the first inclined surface. After the dirt falls on the first inclined surface, it can smoothly slide into the dirt collection chamber 12. During the flushing process, the water level rises but does not exceed the dirt collection chamber 12, thereby controlling the dirt in the dirt collection chamber 12. When a siphon is generated, the dirt can be quickly carried into the pipe. The top of the sludge collection chamber 12 is more than 10mm higher than the highest point inside the siphon channel 2, thus ensuring that the water level rises without exceeding the sludge collection chamber 12. The water surface is located in the lower part of the sludge collection chamber 12 and has the same shape as the sludge collection chamber 12, which is egg-shaped. The bottom surface of the sludge collection chamber 12 is connected to the siphon channel 2 through the second inclined surface, forming a constricted structure. After the dirt falls on the second inclined surface, it can slide smoothly into the interior of the siphon channel 2.

[0057] The siphon channel 2 has an overall S-shaped bend structure. The inlet of the siphon channel 2 is funnel-shaped, and the diameter narrows from the inlet to the outlet. During flushing, it can quickly fill the pipe and form a siphon. During flushing, the water flows through the surface of the washing chamber 11 into the dirt collection chamber 12. The water flow converges in the dirt collection chamber 12, causing the water level in the dirt collection chamber 12 to rise. Since the highest point of the dirt collection chamber 12 is higher than the highest point of the siphon channel 2, the rise in the water level in the dirt collection chamber 12 also creates pressure on the water flow in the siphon channel 2, increasing the discharge speed. When the water flow in the dirt collection chamber 12 rises to the top of the dirt collection chamber 12 (about 3-4 seconds after flushing), the water flow speed at the front end of the siphon channel 2 and the discharge speed at the rear end reach equilibrium, creating a siphon phenomenon inside the siphon channel 2 (4-5 seconds after flushing). The water flow quickly discharges, carrying away the dirt. Because the dirt is concentrated in the dirt collection chamber 12, and the water level in the dirt collection chamber 12 drops rapidly when the siphon occurs, the dirt can be effectively discharged from the siphon channel 2.

[0058] In terms of final rinsing effect, it improves the rinsing effect of small particles by 70%, leaving less than 5 particles, improves the rinsing effect of PP balls by 60%, and improves the rinsing effect of large floating particles by 50%.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
