Description

Technical Field

[0001] The utility model belongs to the field of sanitary ware, and more specifically relates to a noise-reducing drain. Background Art

[0002] The field of sanitary ware technology covers the design, manufacture and application of bathroom equipment and tools. Among them, bathroom equipment is mainly used to clean the body, excrete waste and maintain hygiene. Bathroom equipment mainly includes: wash basins, toilets, showers, bathtubs, etc. In daily life, wash basins, showers and other bathroom equipment need to be connected to the sewer pipes to discharge wastewater or sewage to a centralized collection area through the sewer pipes to keep the bathroom clean. Usually, a drain is installed at the water inlet of the sewer pipe to prevent larger debris from entering the sewer pipe and causing pipe blockage.

[0003] At present, the drains used in wash basins are divided into flip-top drains and pop-up drains in terms of structure; and into square wash basins and round wash basins in terms of shape. When the above drains are in use, when water flows through the drain chamber and enters the sewer, it often causes a lot of air to be sucked into the pipe, and the airflow generated by the air hits the inner wall of the pipe, causing noise, which affects the user's use and reduces the comfort of the use process. Utility Model Content

[0004] The main purpose of this application is to provide a noise-reducing drain that can reduce the amount of air sucked into the pipe, thereby reducing noise and improving user experience and comfort.

[0005] In order to achieve the above objectives, the present application proposes a noise reduction drain, comprising:

[0006] The shell is hollow and its outer wall can be fixed to the drain port;

[0007] The spoiler assembly includes a plurality of rotating blades, which are suspended clockwise or counterclockwise at the hollow position of the shell along the tangent direction of the water flow to form a flow channel, and the direction of the flow channel is set in the opposite direction to the rotation direction of the water flow;

[0008] The flow distribution network is arranged at one end of the shell body facing the water outlet of the pipeline.

[0009] Generally, when a drainer is installed in a sewer pipe, the water will rotate clockwise or counterclockwise to form a vortex, which will inhale more air at the pipe mouth and cause noise. The flow direction of the spoiler component in this solution is opposite to the direction of rotation of the water vortex, thereby interfering with the formation of the water vortex, reducing the amount of air inhaled, and thus reducing noise. The diversion net can evenly distribute the water flow in the sewer pipe, further reducing the amount of air entering the pipe.

[0010] Furthermore, the rotor blade is tiltedly arranged in the shell, the end of the rotor blade facing the inner wall of the shell is an arc surface, and the end away from the arc surface is a connecting surface, and the connecting surfaces of several rotor blades are cross-arranged to form a flow channel.

[0011] The arc surface can fit the inner surface of the shell, effectively avoiding the formation of gaps between the impeller and the inner wall of the shell. When water flows through the gaps, bubbles may be formed. When the bubbles enter the sewer pipe and collide with the sewer pipe, noise may be caused. Therefore, in order to effectively avoid the generation of bubbles, the side of the impeller facing the inner surface of the shell is designed to be an arc surface structure.

[0012] Furthermore, a clamping groove is provided on the connecting surface, and a plurality of rotating blades are fixedly clamped through the clamping groove, and the arc surface is fixedly connected to the inner wall of the shell.

[0013] The adjacently arranged rotor blades can be connected to each other through the clamping grooves, thereby improving the overall stability of the rotor blades.

[0014] Furthermore, a connecting rib is provided on the arc surface, and an arc groove is provided at a position inside the shell corresponding to the connecting rib, and the connecting rib is placed in the arc groove.

[0015] In this solution, a plurality of rotating blades form a whole, namely, a spoiler assembly. By mutually nesting the connecting ribs and the arc-shaped grooves, the spoiler assembly can be screwed into the shell, which is convenient for installation and disassembly.

[0016] Furthermore, the inclination angle of the rotary blade relative to the interior of the shell is an acute angle.

[0017] The inclination angle between the rotor blade and the inner surface of the shell is designed to be an acute angle, which will increase the contact area between the water flow and the rotor blade relative to the vertical angle, and effectively interfere with the formation of the water flow vortex.

[0018] Furthermore, the end of the rotary blade away from the water outlet is the water inlet end, and the end of the rotary blade close to the water outlet is the water outlet end. The tails of the water inlet end and the water outlet end are both provided with a raised portion, and the raised portion of the water inlet end and the raised portion of the water outlet end are arranged in opposite directions.

[0019] The raised portion can effectively guide the inflow and outflow of water flow, and can effectively alleviate the instantaneous impact force of the water flow on the rotor blades, thereby reducing the noise caused by the water flow impacting the rotor blades.

[0020] Furthermore, a drainage groove is provided on the shell along the water flow inflow direction which is the same as the water flow through the channel.

[0021] The diversion groove can guide a part of the water flow hitting the inner wall of the shell to flow toward the rotary blade. Since its rotation direction is the same as the direction of flowing through the channel, it can further offset the rotation direction of the water flow vortex, thereby further interfering with the formation of the water flow vortex.

[0022] Furthermore, the diversion net is provided with a plurality of evenly arranged diversion holes for passing water flow.

[0023] The evenly arranged diversion holes can evenly distribute the water flow in the sewer pipe and reduce the entry of air into the pipe.

[0024] The noise reduction drainer proposed by the utility model has the following beneficial effects:

[0025] (1) By providing a spoiler assembly in the utility model, the direction of the water flowing through the channel is opposite to the direction of rotation of the water vortex, thereby interfering with the formation of the water vortex, reducing the amount of air inhaled, and thus reducing noise.

[0026] (2) By providing a diversion net in the utility model, the water flow can be evenly distributed in the sewer pipe, further reducing the entry of air into the pipe.

[0027] (3) The utility model provides an arc surface on the impeller, which can fit the inner surface of the shell, effectively avoiding the formation of a gap between the impeller and the inner wall of the shell. When water flows through the gap, bubbles may be formed. When the bubbles enter the sewer pipe and collide with the sewer pipe, noise may be caused. Therefore, in order to effectively avoid the generation of bubbles, the side of the impeller facing the inner surface of the shell is designed to be an arc surface structure.

[0040] Example

[0041] In the prior art, when water flows through the sewer chamber and enters the sewer, it often causes a lot of air to be sucked into the pipe, and the airflow generated by the air hits the inner wall of the pipe to cause noise, which affects the user's use and reduces the comfort of the use process.

[0042] Based on this, in order to solve the technical problem of high noise in the process of water flowing through the drain into the sewer in the prior art, this embodiment proposes a noise reduction drain, referring to Figure 1 and Figure 3 , including: a shell 1, a spoiler assembly and a diversion net 3. In this embodiment, the shell 1 is a hollow design, that is, it presents a pipe structure with two ends connected, and the outer wall of the pipe structure can be placed at the drain outlet of the sewer. The spoiler assembly is fixed inside the shell 1. For details, refer to Figure 1 , Figure 2 and Figure 4 The spoiler assembly includes three mutually cross-arranged rotor blades 2, wherein any rotor blade 2 is suspended clockwise or counterclockwise in the hollow position of the shell 1 along the tangent direction of the water flow to form a flow passage, and the direction of the flow passage is set in the opposite direction of the water flow rotation direction. A fixed connection such as Figure 3 The diverter net 3 shown is oriented toward the drain. When the drain is installed in the drain pipe, the water will rotate clockwise or counterclockwise to form a vortex, which will inhale more air at the pipe mouth and cause noise. Therefore, the direction of the flow passage of the spoiler assembly of this solution is opposite to the direction of rotation of the water vortex, thereby interfering with the formation of the water vortex, reducing the amount of air inhaled, and thus reducing noise. The diverter net 3 can evenly distribute the water flow in the drain pipe, further reducing the amount of air entering the pipe.

[0043] In this embodiment, the rotor blade 2 is tilted relative to the inside of the shell 1, and its tilt angle is an acute angle. The tilt angle between the rotor blade 2 and the inner surface of the shell 1 is designed to be an acute angle, which will increase the contact area between the water flow and the rotor blade 2 relative to the vertical angle, and effectively interfere with the formation of the water flow vortex. In this embodiment, the diversion net 3 is provided with a plurality of evenly arranged diversion holes 31 for passing water. The evenly arranged diversion holes 31 can evenly distribute the water flow in the sewer pipe and reduce the air entering the pipe. Among them, in order to improve the diversion effect, refer to Figure 2 The thickness of the rotor blade 2 along the water entry direction is distributed in a decreasing manner, that is, the rotor blade 2 is thinner at a location close to the diverter net 3 than at a location far from the diverter net 3 .

[0044] It should be noted that in this embodiment, since the water flow will rotate clockwise and fall to form a vortex when the water drainer in the northern hemisphere is discharged, the direction of the water flow through the channel in the water drainer in this embodiment for the northern hemisphere is counterclockwise; conversely, since the water flow will rotate counterclockwise and fall to form a vortex when the water drainer in the southern hemisphere is discharged, the direction of the water flow through the channel in the water drainer in this embodiment for the southern hemisphere is clockwise. During the installation of the noise reduction drainer designed in this scheme, one end with the diverter net 3 needs to be installed with the diverter net 3 aligned with the drain outlet of the sewer pipe, that is, the rotary blade 2 is above the diverter net 3.

[0045] In some embodiments, reference Figure 2 The rotor blade 2 is tilted and arranged in the shell 1. The end of the rotor blade 2 facing the inner wall of the shell 1 is a circular arc surface 22, and the end away from the circular arc surface 22 is a connecting surface 21. The connecting surfaces 21 of several rotor blades 2 are arranged crosswise to form a flow passage. The circular arc surface 22 fits with the inner wall of the shell 1 and is fixed together. The circular arc surface 22 can fit the inner surface of the shell 1, effectively avoiding the formation of gaps between the rotor blade 2 and the inner wall of the shell 1. When water flows through the gap, bubbles may be formed. When the bubbles enter the sewer pipe and collide with the sewer pipe, noise may be caused. Therefore, in order to effectively avoid the generation of bubbles, the side of the rotor blade 2 facing the inner surface of the shell 1 is designed as a circular arc surface 22 structure.

[0046] Based on the above embodiment, a clamping groove 23 is provided in the middle of the connection surface 21, and the three rotor blades 2 are fixedly connected through the clamping groove 23. The clamping groove 23 can clamp the adjacent rotor blades 2 to each other, thereby improving the overall stability of the rotor blades 2.

[0047] In some embodiments, in order to facilitate the removal or installation of the spoiler assembly from the shell 1, a connecting rib is provided on the arc surface 22 of the rotary blade 2 on one side relative to the inner surface of the shell 1, and an arc groove is provided at a position on the inner surface of the shell 1 corresponding to the connecting rib, and the connecting rib is placed in the arc groove. When the spoiler assembly needs to be installed into the shell 1 or removed from the shell 1, the spoiler assembly is directly screwed into the shell 1 through the arc groove, and a limiting platform is provided in the shell 1. When the spoiler assembly is screwed into place, the limiting platform abuts against the rotary blade 2 of the spoiler assembly to prevent the rotary blade 2 from falling. In this solution, a plurality of rotary blades 2 form a whole, that is, a spoiler assembly. By mutually nesting the connecting rib and the arc groove, the spoiler assembly can be screwed into the shell 1, which is convenient for installation and removal.

[0048] In some embodiments, in order to further reduce noise, the end of the impeller 2 away from the water outlet is set as the water inlet end, and the end of the impeller 2 close to the water outlet is set as the water outlet end. The tails of the water inlet end and the water outlet end are both arc-shaped transitions with a raised portion 24, and the raised portion 24 of the water inlet end is set in the opposite direction to the raised portion 24 of the water outlet end. The raised portion 24 can effectively guide the inflow and outflow of water flow, and can effectively alleviate the instantaneous impact force of water flow on the impeller 2, thereby reducing the noise caused by the impact of water flow on the impeller 2.

[0049] In some embodiments, a drainage groove is preset on the housing 1 along the direction of water flow inflow, which is the same as the direction of the water flow through the channel. The drainage groove can guide a part of the water flow that hits the inner wall of the housing 1 to flow toward the rotor 2. Since its rotation direction is the same as the direction of the water flow through the channel, it can further offset the rotation direction of the water flow vortex, thereby further interfering with the formation of the water flow vortex.

[0050] Comparative Example

[0051] In order to illustrate the technical effect improved by the technical solution adopted by the utility model, a common drainer on the market is selected for comparison with the product produced by the utility model, wherein the height of the shell of the product is 30 mm, the diameter is 35 mm, and the direction of the rotating blades is counterclockwise.

[0052] First, we use a common water discharger. We can see that a more obvious vortex is formed when the water is discharged. Figure 5 , tested by decibel, the average decibel value is 58dB.

[0053] Then remove the conventional drainer, use the drainer produced by the utility model, and install the diverter net downward (that is, align the diverter net with the water inlet of the drain pipe). The vortex formed when draining is smaller. Figure 6 , according to the decibel test, the noise decibel when launching into the water is 44dB.

[0054] From the comparison between the two groups, it can be seen that the noise level of the drain produced by the drain device of the utility model is reduced, especially when draining the water at the end, the sound produced is greatly improved.

[0055] The above is only for explaining the implementation mode of the utility model and is not used to limit the utility model. For those skilled in the art, any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the utility model without creative work should be included in the protection scope of the utility model.
