Example one

As shown in fig. 1 to 2, the embodiment provides a low-noise waste water valve for a water purifier, including a driving device 100 and a valve body 200, where the driving device 100 includes a coil 110, an iron core 120, a spring 130 and a valve plate 140, the valve body 200 is provided with an inner cavity 210, a water inlet channel 220 and a water outlet channel 230, the inner cavity 210 is provided with a buffer chamber 300, the buffer chamber 300 includes a main channel 310 and a plurality of arc branch channels 320, the water inlets of the arc branch channels 320 are all communicated with the water inlet of the main channel 310, and the water outlets of the arc branch channels 320 are all communicated with the water outlet of the main channel 310. An annular wall 240 is arranged in the inner cavity 210, the inner cavity 210 is divided into a water inlet cavity 250 and a water outlet cavity 260 by the annular wall 240, the water inlet flow passage 220 is communicated with the water inlet cavity 250, the water outlet flow passage 230 is communicated with the water outlet cavity 260, and the buffer cavity 300 is arranged in the water outlet cavity 260. Annular wall 240 is provided with orifice 241 and outlet opening 242 such that inlet chamber 250 communicates with the inlet of primary channel 310 through orifice 241 and the outlet of primary channel 310 communicates with outlet channel 230 through outlet opening 242.

Further, an opening 243 is formed above the annular wall 240 to communicate the inlet chamber 250 with the outlet chamber 260. The driving device 100 is a mechanism that generates a driving force by using an electromagnetic driving principle, and the driving force may be in a linear type or a rotary type. The control coil 110 is powered on or off to generate a magnetic field for driving the iron core 120 to move, the magnetic field and the spring 130 generate acting force on the iron core 120, and the iron core 120 drives the valve plate 140 to move, so that the valve plate 140 moves between two positions, namely, the position abutting against the opening 243 above the annular wall 240 and the position far away from the opening 243 above the annular wall 240, to close or open the opening 243 above the water outlet cavity 260 and communicated with the water inlet cavity 250. When the valve plate 140 abuts against the opening 243 on the annular wall 240, the opening 243 is closed, and the water flow (the flow direction is shown as m in fig. 1) flows from the water inlet chamber 250 into the water outlet chamber 260 along the throttle hole 241 on the annular wall 240 and is divided into the main flow passage 310 and the arc-shaped branch flow passage 320; when the valve plate 140 moves away from the opening 243 on the annular wall 240, the opening 243 is opened, and the water flows from the inlet chamber 250 directly into the outlet chamber 260 along the opening 243 and flows directly into the outlet flow passage 230 by bypassing the buffer chamber 300.

The annular wall 240 is arranged in the inner cavity 210, the inner cavity 210 is divided by the annular wall 240 to form the water inlet cavity 250 and the water outlet cavity 260, the water inlet flow passage 220 is communicated with the water inlet cavity 250, the water outlet flow passage 230 is communicated with the water outlet cavity 260, and the buffer cavity 300 is arranged in the water outlet cavity 260, so that water flows into the water inlet cavity 250 from the water inlet flow passage 220, is dispersed to reduce the flow rate, and then enters the buffer cavity 300 in the water outlet cavity 260, and the noise reduction effect of the buffer cavity 300 is improved. The annular wall 240 is provided with the throttle hole 241 and the water outlet hole 242, so that the water inlet chamber 250 is communicated with the water inlet of the main flow channel 310 through the throttle hole 241, and the water outlet of the main flow channel 310 is communicated with the water outlet flow channel 230 through the water outlet hole 242, so that water flows into the water inlet chamber 250 and is dispersed in the water inlet chamber 250, and then flows into the main flow channel 310 in the buffer chamber 300 along the throttle hole 241 on the annular wall 240, and thus, the flow control effect is achieved.

It can be understood that, when the valve plate 140 in this embodiment abuts against the opening 243 above the annular wall 240 to be in the closed state, because the cross-sectional area of the throttle 241 is small, when the water flow enters the water outlet cavity 260 along the throttle 241, a high-pressure high-speed water flow is generated in the water outlet cavity 260, and the high-pressure high-speed water flow collides with the inner wall of the water outlet cavity 260 and the air in the water outlet cavity 260, so as to generate a large high-frequency impact noise. Meanwhile, air is dissolved in the water flow, the solubility of the air is increased along with the increase of the pressure, and if the pressure is reduced, the air dissolved in the water is separated out. If the internal space of the water outlet cavity 260 is large, a large pressure difference is generated between the water inlet side and the water outlet side of the throttle hole 241, and further more gas is separated from the water flow in the water outlet cavity 260, and the separated gas collides with the water flow, which also generates noise.

Therefore, by providing the buffer chamber 300 in the inner chamber 210, the buffer chamber 300 includes the main flow channel 310 and the plurality of arc branch flow channels 320, the water inlets of the arc branch flow channels 320 are all communicated with the water inlet of the main flow channel 310, and the water outlets of the arc branch flow channels 320 are all communicated with the water outlet of the main flow channel 310, so that after the water flows into the inner chamber 210 from the water inlet flow channel 220, the water flows towards the water outlet flow channel 230 along the main flow channel 310 and the plurality of arc branch flow channels 320 of the buffer chamber 300 for splitting. The flow of each runner reduces after the reposition of redundant personnel to can play the effect of speed reduction step-down to rivers, with the impulsive noise that reduces rivers and runner wall impact and cause, arc runner 320 can play certain buffering water conservancy diversion effect to rivers simultaneously, further reduces the produced impulsive noise of rivers impact runner wall. In addition, utilize many runners to shunt the rivers that flow into inner chamber 210, can prevent that rivers from intake runner 220 when flowing into inner chamber 210, the sudden grow in space that is located leads to the pressure that rivers received to reduce suddenly, avoids the air that dissolves in the rivers after pressure reduces suddenly to separate out fast and with rivers collision production noise, improves user's use greatly and experiences.

In a preferred implementation manner of this embodiment, a plurality of flow restricting pillars 330 are disposed in the buffer chamber 300, gaps between sidewalls of the flow restricting pillars 330 form the main flow passage 310, and gaps between sidewalls of the flow restricting pillars 330 and an inner wall of the buffer chamber 300 form a plurality of arc-shaped branch flow passages 320.

It is understood that the flow restricting post 330 is connected to the bottom wall of the outlet chamber 260, and a plurality of flow restricting posts 330 are spaced apart. Furthermore, a cover plate 340 is disposed on the top ends of the plurality of flow-limiting pillars 330 to separate the top ends of the flow-limiting pillars 330 from the opening 243 above the water outlet chamber 260, so as to prevent the water flow from flowing into the main channel 310 and the channel along the top ends of the flow-limiting pillars 330 from the opening 243 and from being curved when the valve plate 140 is away from the opening 243 and is in the open state, so that the water flow can directly flow into the water outlet channel 230 along the upper surface of the cover plate 340.

Thus, the plurality of flow limiting columns 330 are arranged in the buffer cavity 300, the main flow channel 310 is formed by the gaps between the side walls of the plurality of flow limiting columns 330, the plurality of arc branch flow channels 320 are formed by the gaps between the side walls of the flow limiting columns 330 and the inner wall of the buffer cavity 300, the buffer cavity 300 is divided into the main flow channel 310 and the arc branch flow channels 320 by using a simple flow limiting column 330 structure, and the reliability of the whole structure is improved.

In a preferred implementation manner of this embodiment, the sidewall of the flow-limiting column 330 is provided with a flow-guiding arc surface 331, so that an arc-shaped bypass channel 320 is formed between the flow-guiding arc surface 331 and the inner wall surface of the buffer cavity 300.

Therefore, the flow guide arc surface 331 is arranged on the side wall of the flow limiting column 330, so that the arc branch flow passage 320 is formed between the flow guide arc surface 331 and the inner wall surface of the buffer cavity 300, and when water flows in the arc branch flow passage 320 formed between the flow guide arc surface 331 and the inner wall surface of the buffer cavity 300, the water can flow along the flow guide arc surface 331 to realize buffering, and the water is prevented from directly impacting the wall surface of the flow passage to generate large impact noise.

In a preferred implementation manner of this embodiment, the plurality of arc-shaped branch runners 320 are symmetrically disposed on two sides of the main runner 310, and the water outlets of the plurality of arc-shaped branch runners 320 are disposed opposite to each other, so as to form opposite-flushing water flows at the water outlet of the main runner 310.

For convenience of understanding and illustration, the present embodiment takes two arc-shaped branch flow channels 320 as an example, and the two arc-shaped branch flow channels 320 are symmetrically disposed on two sides of the main flow channel 310. Two flow restricting columns 330 are also symmetrically arranged on two sides of the main flow passage 310, and opposite side wall surfaces of the two flow restricting columns 330 are straight surfaces to clamp the linear main flow passage 310. The side wall surfaces of the two flow restricting pillars 330 facing the buffer chamber 300 are flow guiding arc surfaces 331, so that an arc-shaped branch flow passage 320 is formed between the flow restricting pillars 330 and the inner wall surface of the buffer chamber 300.

Further, the flow guiding arc surface 331 bends toward the water inlet of the main flow channel 310 at a position of the flow limiting column 330 near the water outlet of the main flow channel 310, so that the water outlet of the arc-shaped branch flow channels 320 presents a posture slightly facing the water inlet of the main flow channel 310, and the water flow of the two arc-shaped branch flow channels 320 can form an opposite impact with the water flow in the main flow channel 310 while the water flow at the water outlet of the main flow channel 310 is opposite.

So, through setting up many arc branch flow channel 320 at sprue 310 bilateral symmetry, many arc branch flow channel 320's delivery port sets up relatively for rivers along sprue 310 and many arc branch flow channel 320 reposition of redundant personnel back, many rivers form the counterpulsation rivers at sprue 310's delivery port department, with the rivers velocity of flow that reduces sprue 310 delivery port department, prevent that the velocity of flow is too big rivers and air collision production high frequency noise.

In a preferred implementation manner of the present embodiment, the cross-sectional area of the main flow passage 310 gradually increases from the water inlet to the water outlet. The cross-sectional area of the orifice 241 is larger than the cross-sectional area of the inlet of the primary flow passage 310 and smaller than the cross-sectional area of the outlet of the inlet flow passage 220.

So, the sectional area through setting up the main flow passage 310 is crescent from the water inlet to the delivery port for rivers can realize certain pressure release and discharge to outlet flow passage 230 along the in-process that main flow passage 310 flows. Through setting up the cross-sectional area that orifice 241 sectional area is greater than the main flow passage 310 water inlet, and be less than the cross-sectional area of inlet channel 220 delivery port for orifice 241 has certain throttle function simultaneously, avoids orifice 241 sectional area undersize to lead to rivers to be thin, prevents that thin rivers from directly flowing into main flow passage 310 and can not flow into arc runner 320 and shunt.

The second embodiment:

as shown in fig. 3, the present embodiment is different from the first embodiment in that: the plurality of arc-shaped branch runners 320 are respectively located at two sides of the main runner 310, and a water outlet of the arc-shaped branch runner 320 at one side is opposite to a water inlet of the arc-shaped branch runner 320 at the other side, so as to form opposite-flushing water flow in the middle section of the main runner 310.

It should be understood that, in the present embodiment, two arc-shaped branch flow passages 320 are taken as an example for description, and the two arc-shaped branch flow passages 320 are respectively disposed at two sides of the main flow passage 310, wherein one of the two arc-shaped branch flow passages is connected to a front section of the main flow passage 310 close to the throttle hole 241, and the other arc-shaped branch flow passage is connected to a rear section of the main flow passage 310 away from the throttle hole 241. And the water inlet of one of the arc-shaped branch flow channels 320 is connected to the water inlet of the main flow channel 310, and the water outlet is connected to the middle of the main flow channel 310; the other arc-shaped branch flow passage 320 is positioned at the other side, the water inlet is connected to the middle part of the main flow passage 310, and the water outlet is connected to the water outlet of the main flow passage 310.

When water flows into the buffer chamber 300 from the throttle 241 (the flow direction is shown as n in fig. 3), the water is divided into two paths, one path flows along the main flow channel 310, the other path flows along the arc-shaped branch flow channel 320 close to the throttle 241, and finally the two paths are converged at the middle part of the main flow channel 310, and meanwhile, the water flowing along the arc-shaped branch flow channel 320 can generate a certain hedging deceleration effect on the water flowing along the main flow channel 310; and then, the water flow is divided into two paths at the junction again, one path of water flow continuously flows along the main flow channel 310, the other path of water flow flows along the arc branch flow channel 320 relatively far away from the throttling hole 241, and finally the water flow is converged at the water outlet of the main flow channel 310 and is subjected to opposite-impact deceleration again, so that secondary opposite-impact deceleration of the water flow is realized.

In addition, the inventor finds that when the water purifier uses the waste water valve in the prior art, that is, the water outlet cavity 260 is not provided with a plurality of flow channels for flow distribution, the overall noise of the water purifier is 59.5dB, and after the waste water valve in the embodiment is installed in the water purifier, the overall noise of the water purifier is 58.4dB, which is reduced by 1.1dB compared with the prior art.

So, through being located many arc branch runner 320 respectively the main flow passage 310 both sides, and wherein the arc branch runner 320 of one side's delivery port sets up with the arc branch runner 320's of opposite side water inlet relatively for rivers form the offset rivers in the middle section of main flow passage 310 along main flow passage 310 and many arc branch runner 320 reposition of redundant personnel back, many rivers, in order to reduce the velocity of flow of main flow passage 310, prevent that the velocity of flow is too big rivers and air collision from producing high frequency noise.

Example three:

as shown in fig. 4 to 5, the present embodiment is different from the first embodiment in that: the water outlet hole 242 is provided with a flow guiding wall 400 extending outwards from the side wall of the water outlet of the main flow channel 310, and the flow guiding wall 400 and the side wall of the water outlet of the main flow channel 310 form a right angle or an obtuse angle.

It will be appreciated that the guide wall 400 extends outwardly from the outlet sidewall of the main flow passage 310 to form a burst chamber 410 at the outlet. The guide wall 400 causes a water flow (the flow direction is indicated by q in fig. 5) to flow to the outlet of the main channel 310, and a tendency of flowing along the guide wall 400 is generated. Because the guide wall 400 and the side wall of the water outlet of the main channel 310 form a right angle or an obtuse angle, the water flow does not flow away quickly along the guide wall 400, but accumulates at the water outlet of the main channel 310 and gradually expands due to the existence of the surface tension of the liquid, and when the accumulated amount reaches a certain degree, the pressure of the liquid at the position reaches a certain bursting pressure, the water flow can continuously flow through the water outlet of the main channel 310 and flow into the water outlet channel 230. Therefore, the flow rate of the water at the water outlet of the main flow passage 310 is greatly reduced, so as to avoid the high-frequency noise caused by the collision of the excessive flow rate with the air.

The calculation formula of the burst pressure is as follows:

where σ is the surface tension of the liquid, θ _A The advancing contact angle of the liquid front with the channel wall. The divergence angle formed by the flow guide wall 400 and the outlet side wall of the main flow channel 310 is beta. To continue the liquid to travel through the blasting chamber 410, the contact angle θ of the liquid front end with the channel wall _I From theta to theta _A Increase to theta _A+β . The width of the sudden divergence part of the water outlet channel of the main channel 310 is w, and the height of the channel is h.

The divergence angle β formed by the guide wall 400 and the side wall of the water outlet of the main channel 310 is 90 ° or an obtuse angle, and when the divergence angle β is an obtuse angle, the preferable value range is 110 ° to 150 °. For example, as shown in fig. 6, when the divergence angle β is 120 °, the three-phase contact line is longer when the front end of the liquid passes through the divergence angle of 120 ° as compared with when the divergence angle β is 90 °, and the fluid needs to overcome a larger explosion pressure to pass through the explosion chamber 410 at the water outlet of the main flow passage 310, which is more effective in decelerating the fluid.

In addition, the inventor finds that when the water purifier uses the waste water valve in the prior art, namely the water outlet cavity 260 is not provided with a plurality of flow channel branches, the whole noise of the water purifier is 59.5dB, and after the waste water valve with the divergence angle beta of 90 degrees in the embodiment is installed in the water purifier, the whole noise of the water purifier is 56.7dB, which is reduced by 2.8dB.

So, through the water conservancy diversion wall 400 that is equipped with the delivery port lateral wall of autonomic runner 310 and outwards extends at apopore 242, water conservancy diversion wall 400 and the delivery port lateral wall of mainstream canal 310 are the right angle or the obtuse angle sets up, can outwards flow along water conservancy diversion wall 400 when making rivers flow to apopore 242, because the fluid has surface tension, the structure that the sudden widening that water conservancy diversion wall 400 formed can make rivers produce the detention at apopore 242, until the fluid piles up behind the produced pressure surpassing certain threshold value, rivers just can flow into outlet channel 230 from apopore 242, with further reduce the velocity of flow of rivers at apopore 242, avoid the too big and air collision of velocity of flow of rivers to produce high frequency noise.
