[0013] Preferably, one end of the transition chamber communicating with the inlet flow channel is an inlet end, and a cross-sectional area of the inlet end is larger than a cross-sectional area of an outlet of the inlet flow channel.

[0014] Preferably, the end of the transition chamber communicating with the inlet flow channel is an inlet end, and the lowest point of the inlet end is lower than the lowest point of the outlet of the inlet flow channel.

[0015] The toilet comprises a barrel body and the above-mentioned washing pipeline, wherein the water outlet is connected to the washing groove of the barrel body.

[0016] Preferably, it further includes a water inlet pipe, one end of which is connected to the water inlet, and the highest point of the inlet flow channel is not higher than the lowest point of the outlet flow channel, and is not higher than the lowest point of at least one section of the water inlet pipe.

Therefore, when water is taken in, water flows from the water inlet into the washing pipe, pushing the accumulated water in the water storage space to flow forward, so that the water level in the transition chamber gradually rises. When the water level rises above the lowest point of the inlet of the outlet channel, it flows out from the water outlet through the outlet channel. During the water inlet process, the water flowing in from the water inlet is first delayed by the accumulated water in the water storage space, reducing the flow rate, and then is blocked by the first guide slope in the transition chamber and rebounds toward the upper part of the transition chamber. The water flow is softer, and the air in the upper part of the transition chamber and the outlet channel is slowly and sequentially squeezed out to avoid air accumulation in the upper part of the transition chamber, effectively reducing the noise of breaking air during water discharge.

[0042] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0043] like Figures 1 to 11 As shown, the present invention provides a washing pipeline, comprising an inlet flow channel 10, a transition chamber 30, and an outlet flow channel 20, which are connected in sequence. The inlet of the inlet flow channel 10 is a water inlet 11, and the outlet of the outlet flow channel 20 is a water outlet 21. The lowest point of the outlet of the inlet flow channel 10 is lower than the lowest point of the inlet of the outlet flow channel 20. The outlet of the inlet flow channel 10 and the inlet of the outlet flow channel 20 are respectively connected to the transition chamber 30. The bottom of the transition chamber 30 is provided with a first guide slope 31, which gradually rises in a direction away from the outlet of the inlet flow channel 10.

[0044] In the present invention, an inlet flow channel 10 and a transition chamber 30 are provided on the basis of the outlet flow channel 20, and the lowest point of the outlet of the inlet flow channel 10 is lower than the lowest point of the inlet of the outlet flow channel 20, so that a water storage space is formed at the bottom of the inlet flow channel 10 and the transition chamber 30, and water can be stored in the water storage space. When water is inletted, water flows from the water inlet 11 into the washing pipeline, pushing the accumulated water in the water storage space to flow forward, so that the water level in the transition chamber 30 gradually rises. When the water level rises above the outlet flow channel 20, the water level in the transition chamber 30 rises. When the inlet of the water chamber 20 reaches the lowest point, it flows out from the water outlet 21 through the outlet flow channel 20. During the water inlet process, the water flowing in from the water inlet 11 is first delayed by the accumulated water in the water storage space, reducing the flow rate, and then blocked by the first guide slope 31 in the transition chamber 30 and rebounded toward the upper part of the transition chamber 30. The water flow is softer, and the air in the upper part of the transition chamber 30 and the outlet flow channel 20 is slowly and sequentially squeezed out, avoiding the accumulation of air in the upper part of the transition chamber 30, and effectively reducing the noise of breaking air during the water outlet process.

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

[0046] More specifically, a second guide slope 32 is provided at the top of the transition chamber 30, gradually descending as it moves away from the inlet of the outlet flow channel 20. This arrangement allows water flowing into the upper portion of the transition chamber 30 to be rebounded by the second guide slope 32 toward the inlet of the outlet flow channel 20, resulting in smoother water flow, less turbulence, and further reduced noise.

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

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

[0049] In this embodiment, the inlet channel 10 and the outlet channel 20 both extend in a straight line or in a curved manner in the horizontal direction. In the horizontal direction, the transition chamber 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 chamber 30. The first guide slope 31 is arranged at the bottom wall of the transition chamber 30, with an angle of 30° to the horizontal plane. The second guide slope 32 is arranged at the top wall of the transition chamber 30, with an angle of 20° to the horizontal plane. Water flowing in from the water inlet 11, after passing through the inlet channel 10, is first rebounded by the first guide slope 31 to the second guide slope 32, and then rebounded by the second guide slope 32 to the outlet channel 20, and finally flows out from the water outlet 21.

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

[0051] Specifically, the highest point of the inlet flow channel 10 is no higher than the lowest point of the outlet flow channel 20. This arrangement ensures that the water storage space encompasses the entire inlet flow channel 10, preventing the water introduced from the water inlet 11 from coming into direct contact with air. Exhaust is performed by pushing the accumulated water, further reducing noise.

[0052] More specifically, the end of the transition chamber 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 the water to lag after flowing out of the outlet of the inlet channel 10 due to the increased flow cross-section, thereby reducing the air-breaking sound.

[0053] In this embodiment, the lowest point of the introduction end is lower than the lowest point of the outlet of the introduction channel 10. The above arrangement allows the water to sink toward the bottom of the introduction end after flowing out of the outlet of the introduction channel 10, further producing a hysteresis effect and thereby reducing the air breaking sound.

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

[0055] The present invention further provides a toilet, comprising a barrel body 100 and the above-mentioned washing pipeline, wherein the water outlet 21 is connected to the washing groove 101 of the barrel body 100 .

[0056] In the toilet of the present invention, an inlet flow channel 10 and a transition chamber 30 are provided on the basis of the outlet flow channel 20, and the lowest point of the outlet of the inlet flow channel 10 is lower than the lowest point of the inlet of the outlet flow channel 20, so that a water storage space is formed at the bottom of the inlet flow channel 10 and the transition chamber 30. Water can be accumulated in the water storage space, so that when water is inletted, water flows from the water inlet 11 into the washing pipe, pushing the accumulated water in the water storage space to flow forward, so that the water level in the transition chamber 30 gradually rises. When the water level rises above the outlet flow channel 20, the water level rises to the bottom of the inlet flow channel 10. When the inlet of the flow channel 20 reaches the lowest point, it flows out from the water outlet 21 through the outlet flow channel 20. During the water inlet process, the water flowing in from the water inlet 11 is first delayed by the accumulated water in the water storage space, reducing the flow rate, and then blocked by the first guide slope 31 in the transition chamber 30 and rebounded toward the upper part of the transition chamber 30. The water flow is softer, and the air in the upper part of the transition chamber 30 and the outlet flow channel 20 is slowly and sequentially squeezed out, avoiding the accumulation of air in the upper part of the transition chamber 30, effectively reducing the noise of breaking air during the water outlet 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 flow channel 10 is no higher than the lowest point of the outlet flow channel 20, and no 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 through the water inlet pipe 200, can fill the inlet flow channel 10, achieving optimal noise reduction.

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

[0059] In another embodiment, the water inlet 11 is located on one side of the washing trough 101 in the width direction, and the transition chamber 30 and the outlet flow channel 20 are located on the other side of the washing trough 101 in the width direction. At this time, water enters the right side / or left side of the toilet, the inlet flow channel 10 is lower than the outlet flow channel 20, and the inlet flow channel 10 sinks as a whole. After going around the back circle of the toilet to the other side, it is connected to the outlet flow channel 20 through the transition chamber 30. When not in use, some water is stored in the drop space. After starting the flushing, the water flow first fills the sinking space, and then overflows and discharges silently. The water then passes through the transition chamber 30 and the outlet flow channel 20 on different sides for secondary silencing and diversion, ultimately achieving a silent water discharge effect.

[0060] In another embodiment, the water inlet 11 is located at the rear side of the barrel 100, facing the middle position of the washing trough 101 in the width direction. The transition chamber 30 and the outlet flow channel 20 are located on one side of the washing trough 101 in the width direction. The inlet flow channel 10 bends and extends from the middle position of the washing trough 101 to one side. At this time, water enters the middle of the toilet, the inlet flow channel 10 is lower than the outlet flow channel 20, and the inlet flow channel 10 sinks as a whole. After going around the back of the toilet to the left and / or right sides, it is connected to the outlet flow channel 20 through the transition chamber 30. When not in use, some water is stored in the drop space. After starting the flush, the water first fills the sinking space, and then overflows and discharges silently. The water then passes through the transition chamber 30 and the outlet flow channel 20 on the left and / or right sides for secondary silencing and diversion, ultimately achieving a silent water discharge effect.

[0061] In this embodiment, the washing pipeline is made of ceramic material, bonded to the barrel body 100, and is located on the left or right side of the width direction of the washing tank 101. The water inlet pipe 200 is bent with an inclination, and the lowest point of the bend is higher than the highest point of the water inlet 11, and the highest point of the water inlet 11 is lower than the lowest point of the outlet flow channel 20, so that the lower part of the water inlet pipe 200, the entire inlet flow channel 10 and the lower part of the transition chamber 30 form a water storage space, such as Figure 6 As shown in the cross-section area in the washing pipeline, water is accumulated in the water storage space. The first guide slope 31 and the second guide slope 32 are arranged obliquely to guide the water in the water storage space to rebound and rush out of the outlet flow channel 20.

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

[0063] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
