Description

Technical Field

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

[0002] In existing toilets with outflow channels, during washing, water typically flows from the inlet fitting into the outflow channel and then from the outflow channel into the bowl of the toilet bowl. During this process, air is pushed out of the channel, producing a loud whistling sound, which affects the user experience. Utility Model Content

[0003] The purpose of this invention is to provide a washing pipe and toilet that can reduce the noise of water flowing through the outlet channel.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] Cleaning the pipes, including:

[0006] The inlet of the inlet channel is a water inlet;

[0007] The outlet of the outflow channel is a water outlet, and the lowest point of the outlet of the inflow channel is lower than the lowest point of the inflow of the outflow channel.

[0008] The transition cavity is connected to the outlet of the inlet channel and the inlet of the outlet channel. The bottom of the transition cavity is provided with a first guide slope, which gradually rises in the direction away from the outlet of the inlet channel.

[0009] Preferably, the projection of the outlet of the inlet channel along the axial direction within the transition cavity is at least partially located on the first guide slope.

[0010] Preferably, the top of the transition cavity is provided with a second guide slope, which gradually descends in a direction away from the outlet flow channel inlet.

[0011] Preferably, the projection of the inlet of the outlet channel along the axial direction within the transition cavity is at least partially located on the second guide slope.

[0012] Preferably, the highest point of the inlet channel is not higher than the lowest point of the outlet channel.

[0013] Preferably, the end of the transition cavity that connects to the inlet channel is the inlet end, and the cross-sectional area of ​​the inlet end is larger than the cross-sectional area of ​​the outlet of the inlet channel.

[0014] Preferably, the end of the transition cavity that connects to the inlet channel is the inlet end, and the lowest point of the inlet end is lower than the lowest point of the outlet of the inlet channel.

[0015] A toilet, including a tub and the aforementioned washing pipe, wherein the water outlet is connected to the washing trough of the tub.

[0016] Preferably, the system also includes an inlet pipe, one end of which is connected to the inlet. The highest point of the inlet channel is not higher than the lowest point of the outlet channel, and is not higher than the lowest point of at least one cross-section of the inlet pipe.

[0017] Preferably, the water inlet, the transition cavity, and the outlet channel are located on the same side of the width direction of the washing tank.

[0018] Preferably, the water inlet is located on one side of the width direction of the washing tank, and the transition cavity and the outlet channel are located on the other side of the width direction of the washing tank.

[0019] Preferably, the water inlet is located on the rear side of the barrel, directly opposite the middle position of the washing tank in the width direction, and the transition cavity and the outlet channel are located on one side of the washing tank in the width direction.

[0020] The beneficial effects of this utility model are:

[0021] An inlet channel and a transition cavity are set up on the basis of the outlet channel, and the lowest point of the outlet channel outlet is lower than the lowest point of the outlet channel inlet, so that a water storage space is formed at the bottom of the inlet channel and the transition cavity. Water can be stored in the water storage space. When water is introduced, the water flows from the inlet into the washing pipe, pushing the water stored in the water storage space forward, causing the water level in the transition cavity to gradually rise. When the water level rises above the lowest point of the outlet channel inlet, it flows out from the outlet through the outlet channel. During the water introduction process, the water flowing in from the inlet is first delayed by the water stored in the water storage space, reducing the flow rate. Then it is blocked by the first guide slope in the transition cavity and bounces towards the upper part of the transition cavity. The water flow is more gentle, slowly and sequentially squeezing out the air in the upper part of the transition cavity and the outlet channel, avoiding the accumulation of air in the upper part of the transition cavity, and effectively reducing the noise of air breaking during the water outlet process.

[0042] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] like Figures 1 to 11 As shown, this utility model provides a washing pipeline, including an inlet channel 10, a transition cavity 30, and an outlet channel 20 connected in sequence. The inlet of the inlet channel 10 is an inlet 11, and the outlet of the outlet channel 20 is an outlet 21. The lowest point of the outlet of the inlet channel 10 is lower than the lowest point of the inlet of the outlet channel 20. The outlet of the inlet channel 10 and the inlet of the outlet channel 20 are respectively connected to the transition cavity 30. A first guide slope 31 is provided at the bottom of the transition cavity 30, and the first guide slope 31 gradually rises in the direction away from the outlet of the inlet channel 10.

[0044] In this invention, an inlet channel 10 and a transition cavity 30 are provided on the basis of the outlet channel 20. The lowest point of the outlet of the inlet channel 10 is lower than the lowest point of the inlet of the outlet channel 20, thereby forming a water storage space at the bottom of the inlet channel 10 and the transition cavity 30. Water can accumulate in the water storage space. When water is introduced, the water flows from the inlet 11 into the washing pipe, pushing the accumulated water in the water storage space forward, causing the water level in the transition cavity 30 to gradually rise. When the water level rises above the outlet channel 20, the water level gradually increases. When the water reaches the lowest point of the inlet of channel 20, it flows out from the outlet 21 through the outlet channel 20. During the water intake process, the water flowing in from the inlet 11 is first delayed by the water in the water storage space, which reduces the flow rate. Then, it is blocked by the first guide slope 31 in the transition cavity 30 and bounces towards the upper part of the transition cavity 30, making the water flow more gentle. This slowly and sequentially squeezes out the air in the upper part of the transition cavity 30 and the outlet channel 20, preventing the air from accumulating in the upper part of the transition cavity 30 and effectively reducing the noise of air breaking during the water output process.

[0045] Specifically, the projection of the outlet of the inlet channel 10 along the axial direction within the transition cavity 30 is at least partially located on the first guide slope 31. This arrangement allows the water flow entering the transition cavity 30 from the outlet of the inlet channel 10 to be more directly and efficiently blocked and bounced off by the first guide slope 31.

[0046] More specifically, a second guide slope 32 is provided at the top of the transition cavity 30, and the second guide slope 32 gradually descends in the direction away from the inlet of the outlet channel 20. The above arrangement allows the water flowing into the upper part of the transition cavity 30 to be bounced back towards the inlet of the outlet channel 20 by the second guide slope 32, making the water flow smoother, avoiding turbulence, and further reducing noise.

[0047] More specifically, the axial projection of the inlet of the outlet channel 20 within the transition cavity 30 is at least partially located on the second guide ramp 32. This arrangement allows the water flowing into the upper part of the transition cavity 30 to be more directly and efficiently bounced back into the inlet of the outlet channel 20 by the second guide ramp 32.

[0048] More specifically, the angle between the first guide slope 31 and the horizontal plane is in the range of 20°-40°, and the angle between the second guide slope 32 and the horizontal plane is in the range of 10°-30°.

[0049] In this embodiment, both the inlet channel 10 and the outlet channel 20 extend in a straight line or bend along the horizontal direction. In the horizontal direction, the transition cavity 30 is located between the outlet of the inlet channel 10 and the inlet of the outlet channel 20. The outlet of the inlet channel 10 and the inlet of the outlet channel 20 are respectively connected to the opposite sides of the transition cavity 30. The first guide slope 31 is disposed at the bottom wall of the transition cavity 30, with an angle of 30° with the horizontal plane. The second guide slope 32 is disposed at the top wall of the transition cavity 30, with an angle of 20° with the horizontal plane. The water flowing in from the inlet 11, after passing through the inlet channel 10, is first bounced by the first guide slope 31 to the second guide slope 32, and then bounced by the second guide slope 32 to the outlet channel 20, and finally flows out from the outlet 21.

[0050] In other embodiments, the extension directions of the inlet channel 10 and the outlet channel 20 can also be set slightly inclined, for example, the angle between their extension directions and the horizontal direction is 1° or 2°, etc. There are no process restrictions here, as long as the water storage space can accumulate water.

[0051] Specifically, the highest point of the inlet channel 10 is not higher than the lowest point of the outlet channel 20. This arrangement ensures that the water storage space includes the entire inlet channel 10, so that the water introduced from the inlet 11 does not come into direct contact with the air. By pushing the accumulated water to perform air venting, noise is further reduced.

[0052] More specifically, the end of the transition cavity 30 that connects to the inlet channel 10 is the inlet end, and the cross-sectional area of ​​the inlet end is larger than the cross-sectional area of ​​the outlet of the inlet channel 10. This arrangement causes a delay effect in the water flow after it exits the outlet of the inlet channel 10 due to the increased flow cross-section, thereby reducing the whistling sound.

[0053] In this embodiment, the lowest point of the inlet end is lower than the lowest point of the outlet of the inlet channel 10. This arrangement causes the water to flow downwards towards the bottom of the inlet end after flowing out of the outlet of the inlet channel 10, further creating a lag effect and reducing the whistling sound.

[0054] In this embodiment, the inlet 11 has a diameter of 27mm, the lowest point of the outlet channel 20 is 30mm-50mm higher than the lowest point inside the water storage space, the overall length of the outlet channel 20 and the transition cavity 30 ranges from 70mm to 130mm, preferably 100mm, the length of the outlet channel 20 ranges from 80mm to 100mm, the length of the transition cavity 30 ranges from 50mm to 60mm, and the length of the outlet channel 20 is greater than 1.5 times the length of the transition cavity 30; for example Figure 7 and Figure 8 As shown, along the direction away from the inlet channel 10, the width of the transition cavity 30 gradually decreases, and along the direction away from the transition cavity 30, the width of the outlet channel 20 gradually decreases. From the transition cavity 30 to the outlet channel 20, the overall width gradually transitions from 100mm to 50mm; Figures 9-11 As shown, the inlet channel 10 has a circular cross-section, and the outlet channel 20's cross-section gradually decreases in width from bottom to top. The transition cavity 30's cross-section also gradually decreases in width from bottom to top. From the transition cavity 30 to the outlet channel 20, the overall cross-sectional area gradually decreases, and the cross-sectional area of ​​the end of the transition cavity 30 facing away from the outlet channel 20 is 4700 mm². 2 The cross-sectional area at the connection between the transition cavity 30 and the outlet flow channel 20 is 1000 mm². 2 The cross-sectional area at the final outlet 21 is 600 mm². 2 This helps ensure the water pressure required for flushing.

[0055] This utility model also provides a toilet, including a bucket body 100 and the above-mentioned washing pipe, with the water outlet 21 connected to the washing trough 101 of the bucket body 100.

[0056] In this toilet, an inlet channel 10 and a transition cavity 30 are provided on the basis of the outlet channel 20. The lowest point of the outlet of the inlet channel 10 is lower than the lowest point of the inlet of the outlet channel 20, so that a water storage space is formed at the bottom of the inlet channel 10 and the transition cavity 30. Water can be stored in the water storage space. When water is introduced, the water flows from the inlet 11 into the flushing pipe, pushing the stored water in the water storage space forward, causing the water level in the transition cavity 30 to gradually rise. When the water level rises above the outlet channel 20, the water level in the transition cavity 30 increases. When the water reaches the lowest point of the outlet channel 20, it flows out from the outlet 21 through the outlet channel 20. During the water intake process, the water flowing in from the inlet 11 is first delayed by the accumulated water in the water storage space, reducing the flow rate. Then, it is blocked by the first guide slope 31 in the transition cavity 30 and bounces towards the upper part of the transition cavity 30, making the water flow more gentle. This slowly and sequentially squeezes out the air in the upper part of the transition cavity 30 and the outlet channel 20, preventing air from accumulating in the upper part of the transition cavity 30 and effectively reducing the noise of air breaking during the water output process.

[0057] Specifically, the toilet also includes a water inlet pipe 200, one end of which is connected to the water inlet 11. The highest point of the inlet channel 10 is not higher than the lowest point of the outlet channel 20, and not higher than the lowest point of at least one cross-section of the water inlet pipe 200. This arrangement ensures that external water, after being introduced into the water inlet 11 via the water inlet pipe 200, can fill the inlet channel 10, achieving optimal noise reduction.

[0058] In this embodiment, the highest point of the bottom wall of the inlet pipe 200 is 15mm-30mm higher than the lowest point of the outlet channel 20, such as... Figures 1-4As shown, the inlet 11, the transition cavity 30, and the outlet channel 20 are located on the same side of the width direction of the washing tank 101. The axis of the inlet channel 10 and the axis of the outlet channel 20 are parallel to each other and are spaced apart in the vertical direction, so that the flow path of the water in the washing pipeline is shorter and the washing of the surface of the washing tank 101 is more timely and efficient.

[0059] In another embodiment, the water inlet 11 is located on one side of the width direction of the wash basin 101, and the transition cavity 30 and the outlet channel 20 are located on the other side of the width direction of the wash basin 101. At this time, water enters from the right side / or left side of the toilet, the inlet channel 10 is lower than the outlet channel 20, the inlet channel 10 sinks as a whole, and after going around the back of the toilet to the other side, it connects to the outlet channel 20 through the transition cavity 30. In the unused state, some water is stored in the drop space. After the flush is started, the water flow first fills the sink space, overflows and then flows out silently. The water then passes through the transition cavity 30 and the outlet channel 20 on different sides for secondary noise reduction and diversion, and finally achieves the effect of silent water flow.

[0060] In another embodiment, the water inlet 11 is located on the rear side of the tub 100, directly opposite the middle of the width direction of the wash basin 101. The transition cavity 30 and the outlet channel 20 are located on one side of the width direction of the wash basin 101. The inlet channel 10 bends and extends from the middle of the wash basin 101 to one side. At this time, water enters from the middle of the toilet, the inlet channel 10 is lower than the outlet channel 20, and the inlet channel 10 sinks as a whole. It goes around the back of the toilet to the left / or right side and then connects to the outlet channel 20 through the transition cavity 30. In the unused state, some water is stored in the drop space. After the flush is started, the water flow first fills the sink space, overflows and then flows out silently. The water then passes through the transition cavity 30 and the outlet channel 20 on the left / or right side for secondary noise reduction and diversion, ultimately achieving a silent water flow effect.

[0061] In this embodiment, the washing pipe is made of ceramic and is bonded to the barrel 100. It is located on the left or right side of the washing tank 101 in the width direction. The inlet pipe 200 is bent at an angle, with the lowest point of the bend higher than the highest point of the inlet 11. The highest point of the inlet 11 is lower than the lowest point of the outlet channel 20, creating a water storage space in the lower part of the inlet pipe 200, the entire inlet channel 10, and the lower part of the transition cavity 30. Figure 6 As shown in the cross-sectional area of ​​the washing pipeline, water accumulates in the water storage space. The first guide slope 31 and the second guide slope 32 are inclined to guide the water in the water storage space to bounce out of the outlet channel 20.

[0062] When the toilet in this embodiment is flushed, water flows from the inlet pipe 200 into the inlet 11, pushing the water in the water storage space to flow. The water overflows and is first guided from below by the first guide slope 31, and then guided from above by the second guide slope 32. The water gradually overflows, flows through the outlet channel 20, and exits from the outlet 21 into the washing tank 101. During the entire process, when the water in the water storage space overflows, it squeezes out the air in the upper part of the transition chamber 30 and the outlet channel 20. This process is gentler than the existing conventional solution, and the sound of water breaking through the air is reduced.

[0063] 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.
