Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the present invention. One skilled in the art, however, will understand that the following description illustrates only a preferred embodiment of the invention and that the invention may be practiced without one or more of these details. In addition, some technical features that are well known in the art are not described in detail in order to avoid obscuring the present invention.

According to an aspect of the present invention, there is provided a waste valve device 100 for a water purifier, as shown in fig. 1 to 4, wherein fig. 1 shows a position of the waste valve device 100 in a water path, and fig. 2 to 4 show a specific structure of the waste valve device 100. The arrows shown in figures 1 and 4 schematically illustrate the direction of flow of water within the water purifier and waste valve assembly 100, respectively.

Referring to fig. 1, the booster pump 410 presses raw water into the reverse osmosis filter element 400 at a high pressure to filter out pure water, and the resulting concentrated water is discharged from the concentrated water outlet of the reverse osmosis filter element 400. The reverse osmosis filter element 400 may include a filter element formed of a single reverse osmosis membrane and a composite filter element formed by combining a reverse osmosis membrane with other filter materials. The water inlet of the waste valve device 100 may be communicated to the concentrate outlet of the reverse osmosis cartridge 400. As shown in fig. 2 to 4, the waste water valve device 100 includes a waste water ratio valve 110 for generating a high pressure inside the reverse osmosis cartridge 400 of the water purifier while discharging the rich water generated from the reverse osmosis cartridge 400.

According to another aspect of the present invention, there is provided a water purifier, which may include any one of the following waste water valve devices 100. The waste valve apparatus 100 may be applied to any suitable water purification machine, including but not limited to direct drinking machines, central water purification machines, and the like.

The waste valve assembly 100 will be described in detail below with reference to fig. 2-4.

The waste valve apparatus 100 may include a waste ratio valve 110 and a water stop assembly 200. The waste ratio valve 110 may comprise various types of waste ratio valves known in the art or that may occur in the future. The waste ratio valve 110 is actually a throttling device that can control the discharge of concentrated water in a certain proportion by throttling the water through the throttling hole 170. The waste water ratio valve 110 is normally open, and the concentrated water generated by the reverse osmosis filter element 400 can be discharged through the restricted hole 170 of the waste water ratio valve 110. It is also the throttling of the waste water ratio valve 110 that creates high pressure within the reverse osmosis cartridge 400 so that water molecules can pass through the reverse osmosis membrane. The pure water generated from the reverse osmosis filter cartridge 400 is discharged through the pure water port of the reverse osmosis filter cartridge 400, and the concentrated water that does not permeate through the reverse osmosis membrane is discharged through the concentrated water outlet of the reverse osmosis filter cartridge 400 and the waste water valve device 100 in sequence. The ratio of pure water to concentrate output of the reverse osmosis cartridge 400 can also be adjusted by varying the size of the restrictor orifice 170 of the waste ratio valve 110. Thus, by selecting an appropriate waste water ratio valve 110, the reverse osmosis cartridge 400 can be optimally used. The water production process of the water purifier and the operation principle of the reverse osmosis filter element 400 are well known to those skilled in the art and will not be described in detail.

The water stopping assembly 200 may include an elastic member 210. The elastic member 210 may be provided on a water flow path of the waste water ratio valve 110. The water flow path may include the inlet flow path 120 and/or the outlet flow path 130 of the waste ratio valve 110. The water stopping assembly 200 may be provided on the water inlet passage 120 of the waste water ratio valve 110; or on the water outlet channel 130 of the waste water ratio valve 110; the water stopping assembly 200 may be disposed on both the inlet flow path 120 and the outlet flow path 130. Influent channel 120 refers to the flow of wastewater in valve 110 upstream of flow restriction orifice 170. The outlet flow path 130 refers to the flow of waste water through the valve 110 downstream of the flow restriction orifice 170.

At least a portion of the elastic member 210 may be made of an elastic material. That is, the elastic member 210 may be entirely made of an elastic material; or one portion of the elastic member 210 may be elastic and the other portion may be rigid. Preferably, the elastic member 210 may be made of rubber or silicon rubber. The rubber and the silica gel have the advantages of low cost, high elasticity, good wear resistance and the like. The elastic member 210 may also be a spring. The elastic member 210 may have a first deformation amount and a second deformation amount. The first amount of deformation may be less than the second amount of deformation. The first and second deformation amounts may be a compression amount or a tension amount. That is, when water impacts the damping device 100, in some embodiments, the resilient member 210 may be compressed; in other embodiments, the elastic member 210 may also be stretched. In the embodiment where the first and second deformation amounts are compression amounts, the first deformation amount may be zero, or an arbitrary number. Alternatively, the elastic member 210 may be said to be in a naturally stretched state or compressed by a small amount when it has a first amount of deformation. In embodiments where the first and second deformation amounts are amounts of stretch, the first deformation amount may be zero, or any number of values. Alternatively, the elastic member 210 may be said to be in a naturally stretched state, or stretched by a small amount, when it has a first amount of deformation. When the elastic member 210 has the first deformation amount, the elastic member 210 may block the water flow passage. At this time, the metering orifice 170 has no water flowing therethrough. The elastic member 210 may conduct the water flow path when it has the second variation. At this time, the restricted orifice 170 has water flowing therethrough. The difference in the first deformation amount less than the second deformation amount may be selected according to the actual structure. The elastic member 210 is stretched or compressed depending on the installation position thereof when water flows through the waste valve device 100. One skilled in the art can select the location of the resilient member 210 and the manner in which the resilient member 210 deforms when water flows through the waste valve assembly 100 as desired.

Generally, in some water purifiers, the reverse osmosis filter element 400 is installed with its concentrate outlet facing downward, i.e., the concentrate outlet is located at the bottom of the reverse osmosis filter element 400, and the waste water ratio valve 110 is located below the reverse osmosis filter element 400. Its advantage is that it is more convenient to install and dismantle the reverse osmosis filter element 400.

However, a phenomenon occurs, when the water is produced in the water purifier and enters a standby state, the water in the reverse osmosis filter element 400 gradually flows out from the concentrated water outlet and the wastewater ratio valve 110 in sequence due to gravity, so that a cavity is formed in the reverse osmosis filter element 400. When the water purifier produces water for the next time, the booster pump 410 needs to fill the pump in the cavity with water first, so as to establish a higher water pressure in the reverse osmosis filter element 400. This can cause a water discharge pause.

The utility model provides an among the waste water valve device 100, through set up elastic component 210 on the inlet channel 120 and/or the outlet channel 130 of waste water ratio valve 110, when can preventing the purifier standby, the water in the reverse osmosis filter core 400 is influenced by the dead weight and is flowed from dense water outlet. During water production, the concentrated water can push the elastic member 210 open (at this time, the elastic member 210 has the second form variable), so that the concentrated water can be normally discharged from the metering hole 170 of the waste water valve 110. When the water purifier is in standby, the water pressure of the concentrated water outlet is from the gravity of the water in the reverse osmosis filter element 400 because the booster pump 410 does not work. Therefore, the elastic member 210 is restored from the second deformation amount to the first deformation amount, and at this time, the water pressure generated by the water in the reverse osmosis filter element 400 is not enough to push the elastic member 210. Therefore, when the water purifier is in standby, the waste water valve device 100 can keep the water pressure in the reverse osmosis filter element 400, and the pressure maintaining effect is achieved. One skilled in the art can adapt the proper elastic member 210 depending on the operating pressure of the reverse osmosis cartridge 400 and the amount of water contained inside during standby.

Thus, when the water purifier is in standby, the water at the concentrated water outlet of the reverse osmosis filter element 400 can be blocked at the waste water valve device 100, and the pressure in the reverse osmosis filter element 400 can be kept enough. When the water purifier is used for producing water, a user can rapidly take water from the water outlet end of the water purifier, so that the phenomenon of water outlet pause can not occur, and the user experience is better.

The elastic member 210 may be fixed to the waste ratio valve 110 in any suitable manner. Preferably, as shown in fig. 2-4, the water stop assembly 200 may further include a sleeve 220. The sleeve 220 may be connected to a drain port of the waste ratio valve 110. The water outlet may include the water inlet 121 and/or the water outlet 131 of the waste water ratio valve 110. That is, the sleeve 220 may be connected to the inlet 121 of the waste water ratio valve 110, and may also be connected to the outlet 131 of the waste water ratio valve 110. The sleeve 220 may be connected to the waste water ratio valve 110 at the water discharge port by any means, such as welding, screwing, etc. The resilient member 210 may be disposed within the sleeve 220 and/or a water passage to which the sleeve 220 is coupled. Thus, the reconstruction of the existing waste water valve device 100 can be reduced, and the waste water valve device 100 has the advantages of few parts, simple structure, easy processing, low cost and the like.

Further, as shown in fig. 2-4, the sleeve 220 may have a central bore. The central hole may have a large-sized section 221, a small-sized section 222, and a step 223 between the large-sized section 221 and the small-sized section 222. The large-size section 221 can be sleeved on the water passing port. In the illustrated embodiment, the sleeve 220 is sleeved over the inlet 121 of the waste water ratio valve 110. Preferably, the inner diameter of the large-sized section 221 may match the outer diameter of the water passing opening. A stopper 140 may be provided in the water passage opening. The elastic member 210 may be caught between the stopper 140 and the step 223. The position-limiting part 140 may be a protrusion with any shape, and the position-limiting part 140 may be located at any suitable position in the water passing opening, as long as it can clamp the elastic member 210 and allow water to pass through. Therefore, the original waste water ratio valve 110 does not need to be changed too much, the design difficulty and the change of processing tools are reduced, and the cost is reduced.

Further, as shown in fig. 3-4, the sleeve 220 may be sleeved over the inlet 121 of the waste water ratio valve 110. The stopper 140 may be provided on an inner circumferential wall of the water inlet 121. The stopper 140 may have a notch 150 along a circumferential direction of an inner circumferential wall of the water inlet 121, see fig. 3. The shape and location of the indentations 150 may be arbitrary. In the embodiment shown in the drawings, four stopper portions 140 are discretely provided along the circumferential direction on the inner circumferential wall of the water inlet 121, and a gap 150 is formed between adjacent two stopper portions 140. In an embodiment not shown, the indentation may also be of any other shape, which may be located at any position inside the water inlet 121. One end of the elastic member 210 is held by the four stoppers 140. Preferably, the elastic member 210 may have a cylindrical shape. The outer diameter of the elastic member 210 is smaller than the inner diameter of the water inlet 121 and larger than the inner diameter of the small-sized section 222 of the central hole. Thus, when the elastic member 210 has the first deformation amount, the elastic member 210 abuts against the step 223 of the center hole, thereby blocking the small-sized section 222 of the center hole. When water is produced, the elastic member 210 is compressed to a second shape variable under the action of water pressure, the elastic member 210 is spaced apart from the step 223, and water entering from the small-sized section 222 of the central hole can flow into the waste water ratio valve 110 through the gap between the elastic member 210 and the step 223, the gap between the side surface of the elastic member 210 and the inner wall of the water inlet 121, and the notch 150, and then flow out of the water outlet 131 after passing through the restricted hole 170.

By sleeving the sleeve 220 on the water inlet 121 of the wastewater ratio valve 110, when the water purifier is in standby, water in the wastewater valve device 100 can be prevented from being stored, other components in the wastewater valve device 100 are prevented from being soaked by water for a long time, the phenomenon of structure aging is prevented, and the service life of the wastewater valve device 100 is effectively prolonged.

Still further, as shown in fig. 3-4, the elastic member 210 may be provided with a plurality of annular protrusions 211 on the outer circumferential surface thereof. The plurality of annular projected ridges 211 may be arranged at intervals along the axial direction of the elastic member 210. The plurality of annular ridges 211 may be the same or different sizes and may be spaced apart by the same or different distances. Thus, at the annular ribs 211, the elastic member 210 has a larger outer diameter, and between the adjacent annular ribs 211, the elastic member 210 has a smaller outer diameter. Thus, the elastic member 210 can maintain its shape by the annular protrusion 211, and the elasticity of the elastic member 210 is increased by the smaller outer diameter, so that the elastic member 210 not only has a greater elasticity and is easy to precisely control the water pressure in the reverse osmosis filter cartridge 400; and after the water pressure is removed, the elastic member 210 can well recover the shape thereof, so that the phenomenon that the water flow channel is conducted when the elastic member 210 has the first deformation amount is avoided.

Preferably, as shown in fig. 2-4, the waste valve assembly 100 may further include a flush solenoid valve 300. The flush solenoid valve 300 may be integrated into the waste ratio valve 110. The flush solenoid valve 300 may be connected in parallel with the waste ratio valve. The flush solenoid valve 300 may include various types of solenoid valves known in the art or that may occur in the future. The flush solenoid valve 300 may be disposed at any position within the waste valve apparatus 100 as long as it can be connected in parallel with the waste valve. The flush solenoid valve 300 may have two states, open and closed. When the water is produced by the water purifier, the flushing solenoid valve 300 is in a closed state. When the water purifier is flushed, the flushing solenoid valve 300 is in an open state. At this time, the water for flushing the reverse osmosis filter cartridge 400 may flow out through the flushing solenoid valve 300. The flush solenoid valve is well known to those skilled in the art, and its specific structure and operation are the same as and similar to those of the prior art, and will not be described in detail. Through the arrangement, the number of parts of the water purifier can be reduced, and the internal structure of the water purifier is simpler.

Further, as shown in fig. 3-4, an internal conduit 160 is provided within the housing of the waste ratio valve 110. The upper end of the built-in pipe 160 may be communicated to one of the water inlet 121 and the water outlet 131 of the waste water ratio valve 110. The lower end of the built-in pipe 160 may be communicated to the other one of the water inlet 121 and the water outlet 131 of the waste water ratio valve 110. In the illustrated embodiment, the upper end of the inner conduit 160 is connected to the water inlet 121, and the lower end of the inner conduit 160 is connected to the water outlet 131. A flush solenoid valve 300 may be connected to the top of the housing. The spool 310 of the flush solenoid valve 300 may be located above the built-in conduit 160. The valve cartridge 310 may have a closed position and an open position. The spool 310 may close the upper end of the inner conduit 160 when in the closed position. The spool 310 may be spaced from the upper end of the inner conduit 160 when in the open position. The structure of the inner pipe 160 may be arbitrary. The restricted orifice 170 of the waste ratio valve 110 is disposed on the side wall of the built-in pipe. With this arrangement, the waste valve device 100 is simple in structure and small in external size.

Still further, as shown in fig. 3-4, the inlet 121 and the outlet 131 of the waste water ratio valve 110 may be disposed at the side of the housing. In this way, the size of the external form of the waste valve device 100 can be further reduced.
