Description

Technical Field

[0001] The present application relates to a building sewage drainage system, in particular to a drainage member for connecting to a sanitary ware, a bottle trap with such a drainage member, and a drainage pipe system with such a drainage member or a bottle trap. Background Art

[0002] A trap (also known as a water collector or air trap) is a fitting installed inside a sanitary appliance or on the drainage pipe section of the appliance. Under normal circumstances, a certain height of water is stored in the trap, which is called a water seal. The static water pressure of the water seal resists the change of air pressure in the drainage pipe, which can isolate the rancid and harmful gases in the drainage pipe system from the indoor air and prevent the gas, insects, etc. in the pipe from entering the room.

[0003] The loss of water seal in the trap is the main cause of odor in the kitchen and bathroom. One of the main reasons for the failure of the water seal is the siphon effect of the fluid. When the sanitary ware drains a large amount of water instantly, the trap itself is filled and forms a siphon effect. After the drainage is completed, the water seal leaves the trap due to the siphon effect. The occurrence of the siphon effect is related to the combination of sanitary ware and the trap, the diameter and length of the drainage pipe, etc.

[0004] When sewage from multi-story buildings is discharged in large quantities, two types of air pressure are formed in the public drainage pipe (i.e., the main drainage pipe), with negative pressure airflow above the sewage and pressurized airflow below the sewage. The negative pressure airflow produces a siphon effect, which draws out the water stored in the trap, causing the water seal to fail. At the same time, the pressurized airflow below produces a back pressure effect due to the need to reduce pressure, pushing the water stored in the trap of the sanitary ware of the lower-floor residents into the room.

[0005] There is a plastic anti-siphon bottle trap, which is provided with a valve. When the negative pressure in the public sewer pipe caused by the flow of sewage causes a siphon effect, the valve can automatically open to balance the negative pressure in the public sewer pipe, prevent the water seal in the trap from being drawn away by the siphon effect, and maintain a sufficient water seal. However, if the production technology does not meet the standards or the installation is incorrect, the valve may overflow. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The disclosure of the present application is described with reference to the accompanying drawings. It should be understood that the drawings are for illustrative purposes only and are not intended to limit the scope of protection of the present application. In the drawings, unless otherwise specified, the same reference numerals are used to refer to the same components. Among them:

[0023] Figure 1 A cross-sectional view schematically shows a drainage member according to an embodiment of the present application; and

[0024] Figure 2 A cross-sectional view of a bottle-type water trap according to an embodiment of the present application is schematically shown. DETAILED DESCRIPTION

[0025] It is easy to understand that according to the technical solution of the present application, without changing the essential spirit of the present application, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present application, and should not be regarded as the entirety of the present application or as a limitation or restriction on the technical solution of the present application.

[0026] The directional terms such as up, down, left, right, front, and back mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to different positions and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0027] According to one embodiment of the present application, the drainage component is combined Figure 1 , it can be seen that the drainage member 100 includes: a housing 1, a water inlet channel 2 provided in the housing 1, a drainage channel 3 provided at the periphery of the housing 1, and an exhaust channel 4 provided in the housing 1. The exhaust channel 4 is provided to connect the water inlet channel 2 and the drainage channel 3. The water inlet channel 2 is configured to be cylindrical, for example, and the drainage channel 3 is configured to be cylindrical, for example.

[0028] The drainage component is located below the sanitary ware. The sewage discharged from the sanitary ware flows into the drainage component through the water inlet channel 2 and flows out of the drainage component through the drainage channel 3. The gas flowing into the drainage component with the sewage or the gas flow caused by the negative pressure generated in the public drainage pipe can be discharged through the exhaust channel 4.

[0029] In the drainage component according to this embodiment, the exhaust channel 4 connected to the water inlet channel 2 and the drainage channel 3 is provided in the housing 1, so that the negative pressure caused by the flow of sewage in the public drainage pipe can be balanced; because the gas flow quickly passes through the exhaust channel 4, only a small amount of retained sewage is carried out, and when the siphon effect ends, the water will fall back to achieve a water seal effect again. In this way, the water seal in the water trap is minimized from being drawn away by the siphon effect, so as to maintain a sufficient water seal in a simple and reliable manner.

[0030] It should be noted that the expression "a component is disposed in the housing..." means that the component is at least partially located inside the housing or at least partially surrounded by the housing. In addition, the "water inlet channel", "drainage channel" and "exhaust channel" are named according to their iconic functions and should not be interpreted restrictively. In fact, the "water inlet channel" can also be used for air intake, the "drainage channel" can also be used for exhaust, and the "exhaust channel" can also be used for drainage.

[0031] Further in this embodiment, the exhaust channel 4 is adjacent to the water inlet channel 2, and the exhaust channel 4 is parallel to the water inlet channel 2. In this way, a more compact arrangement of the drainage components is achieved.

[0032] In the drainage member according to this embodiment, an air inlet 41 is provided at the lower end of the exhaust passage 4, and the air inlet 41 is communicated with the water inlet passage 2. The air inlet 41 is, for example, arranged at the lowermost end of the exhaust passage 4. In addition, an exhaust port 42 is provided at the upper end of the exhaust passage 4, and the exhaust port 42 is communicated with the drainage passage 3. The exhaust port 42 is, for example, arranged at the uppermost end of the exhaust passage 4.

[0033] In the embodiment shown in the figure, the air inlet 41 is directly connected to the water inlet channel 2, and the air outlet 42 is directly connected to the drainage channel 3. Thus, the gas flow caused by the negative pressure generated in the public drainage pipe carries a small amount of sewage remaining in the water inlet channel 2 directly into the exhaust channel 4 from the water inlet channel 2 through the air inlet 41, and after passing through the exhaust channel 4, directly enters the drainage channel 3 through the air outlet 42.

[0034] In an embodiment not shown in the figure, the air inlet of the exhaust channel can be indirectly connected to the water inlet channel, for example, indirectly connected through another pipeline; and the exhaust port of the exhaust channel can be indirectly connected to the drainage channel, for example, indirectly connected through another pipeline. In addition, the exhaust port of the exhaust channel can be directly or indirectly connected to the public drainage pipe.

[0035] according to Figure 1In the embodiment shown, the exhaust channel 4 includes an inner wall 43 near the water inlet channel 2 and an outer wall 44 near the drainage channel 3, and the lower end of the inner wall 43 is higher than the lower end of the outer wall 44. The inner wall 43 is shared by the exhaust channel 4 and the water inlet channel 2, that is, the inner wall 43 at least partially defines the exhaust channel 4 and the inner wall 43 at least partially defines the water inlet channel 2. The lower end of the inner wall 43 is higher than the lower end of the outer wall 44, so that the gas flow caused by the negative pressure generated in the common drainage pipe is quickly discharged, and the liquid is taken away as little as possible to affect the water seal.

[0036] In the drainage member according to this embodiment, the exhaust passage 4 is spaced apart from the shell 1 in the radial direction, and the exhaust passage 4 is completely located inside the shell 1. That is, the exhaust passage 4 is spaced apart from the shell 1 in the radial direction, and is completely located inside the shell 1. In addition, any part of the exhaust passage 4 in the radial direction does not constitute the whole or part of the shell 1. Figure 1 As used herein, “radial direction” refers to a direction pointing outward from the center of the drainage member in a horizontal direction.

[0037] In this embodiment, a water storage channel 5 is further provided between the exhaust channel 4 and the housing 1, and the water storage channel 5 at least partially surrounds the exhaust channel 4. The water storage channel 5 is connected to the water inlet channel 2 on one hand, and is connected to the drainage channel 3 on the other hand. In radial direction, the water storage channel 5 is located between the water inlet channel 2 and the drainage channel 3.

[0038] When the sanitary ware is draining, the sewage discharged from the sanitary ware flows into the drainage member through the water inlet channel 2, and at least partially flows out of the drainage member through the water storage channel 5 and the drainage channel 3. After the sanitary ware completes draining, part of the liquid remains in the water storage channel 5, thereby forming a water seal.

[0039] Furthermore, in this embodiment, the exhaust port 42 at the upper end of the exhaust channel 4 is located inside the water storage channel 5 in the radial direction. That is to say, the exhaust port 42 of the exhaust channel 4 at least does not exceed the water storage channel 5 in the radial direction, and especially does not exceed the radial outermost side of the water storage channel 5. In this way, after the gas flow caused by the negative pressure generated in the public drainage pipe carries a small amount of sewage remaining in the water inlet channel 2 and is discharged through the exhaust port 42, the water seal liquid level in the water storage channel 5 drops; at this time, the sewage carried and discharged falls into the water storage channel 5, and is not discharged from the drainage component through the drainage channel 3 along with the gas flow, thereby reducing the loss of the water seal.

[0040] The present application also includes a bottle-type water trap having a drainage component of any one or more of the aforementioned embodiments. The technical features and technical effects thereof correspond to the previous description, so they will not be repeated here.

[0041] According to one embodiment of the present application, the bottle-type water trap is combined Figure 2 As shown, the bottle trap 200 includes a closed shell 201 located below the housing of the drainage member, the closed shell is connected to the housing of the drainage member, for example, by a threaded manner, and a seal is also provided at the connection between the closed shell and the housing of the drainage member. The lower end of the bottle trap is thus sealed and a water seal can be accommodated in the closed space formed thereby. The bottle trap also includes a connecting pipe 202 inserted into the water inlet channel of the drainage member for connecting to a sanitary ware. A seal is also provided at the connection between the water inlet channel of the drainage member and the connecting pipe. The closed shell 201 is, for example, configured in a cylindrical shape, and the connecting pipe 202 is, for example, configured in a cylindrical shape.
