Description

Technical Field

[0001] The present invention relates to the technical field of water purifiers, and in particular to a water supply system and an electromagnetic direction-changing valve for a water purifier. Background Art

[0002] In the prior art, water purifiers are usually equipped with a pressure barrel to store purified water after being purified by the filter assembly. However, the water in the pressure barrel is prone to bacterial growth after long-term storage, and the commonly used ultraviolet sterilization lamp cannot kill bacteria that exceed the threshold, resulting in excessive bacterial content in the outlet water, which is harmful to human health. In addition, there are many pipes in the water purifier, and if the water in the pipes does not flow for a long time, it will cause excessive bacterial growth, which will also cause excessive bacterial content in the outlet water.

[0003] The purification component of a water purifier is prone to water flow attenuation after long-term use. The common solution is to replace the filter element of the purification component, but the cost is relatively high. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the defect in the prior art that bacteria are easily bred in the pressure barrel of the water purifier, resulting in excessive bacteria content in the effluent water, and to provide a water supply system for the water purifier and an electromagnetic reversing valve.

[0005] The present invention solves the above technical problems through the following technical solutions:

[0006] The present invention provides a water supply system for a water purifier, the water supply system for the water purifier comprising a pressure barrel, a purification component, a hot water tank, a normal temperature water outlet and a hot water outlet, the water purified by the purification component is stored in the pressure barrel, the water in the pressure barrel is used to be input into the hot water tank, the hot water tank is used to heat the water input into the pressure barrel, the hot water tank is connected to the hot water outlet, and the hot water outlet is used to output the hot water heated by the hot water tank;

[0007] The normal temperature water outlet is directly connected to the purification component, and the normal temperature water outlet is used to directly output the normal temperature water purified by the filter component. A change-of-direction pipeline is provided between the pressure barrel and the normal temperature water outlet, and the change-of-direction pipeline can change the water delivery direction.

[0008] In this solution, the water purified by the purification component is stored in the pressure barrel, and then input into the hot water tank for heating, and the heated water is output from the hot water outlet. The normal temperature water purified by the purification component is directly output through the normal temperature outlet, avoiding the problem of excessive bacteria caused by long-term storage of water in the pressure barrel. In other words, the water stored in the pressure barrel only supplies water to the hot water tank, which is heated and sterilized by the hot water tank and then outputs hot water. The normal temperature water purified by the purification component directly supplies normal temperature water, thereby avoiding the problem of bacterial growth in the pressure barrel. In addition, when the flow rate of the normal temperature outlet is insufficient, the reversing pipeline can change the water outlet direction, so that the water in the pressure barrel can be used to supplement the flow rate of the normal temperature outlet.

[0009] Preferably, the direction-changing pipeline includes a first pipeline and a second pipeline, the first pipeline connects the pressure barrel and the purification component, and a one-way valve and a high-pressure switch are provided on the first pipeline for the flow from the purification component to the pressure barrel;

[0010] The second pipeline is connected with the pressure tank and the normal temperature water outlet, and a manual ball valve is arranged on the second pipeline.

[0011] In this solution, the direction-changing pipeline includes a first pipeline, in which a one-way valve is provided for the flow from the purification component to the pressure barrel, so that the water purified by the purification component can be input into the pressure barrel, but the water in the pressure barrel cannot flow into the normal temperature water outlet through the first pipeline, so that the water in the pressure barrel can only supply water to the hot water tank. The direction-changing pipeline is also provided with a second pipeline, and a manual ball valve is provided on the second pipeline. Opening the manual ball valve can restore the water supply from the pressure barrel to the normal temperature water outlet.

[0012] Preferably, when the flow rate of the normal temperature water outlet is insufficient, the manual ball valve is opened to allow the pressure barrel to supply water to the normal temperature water outlet.

[0013] In this solution, when the flow attenuation of the purification component is relatively large or the purification component is blocked, the water supply from the pressure barrel to the normal temperature water outlet can be restored by opening the manual ball valve, thereby ensuring the water flow rate of the normal temperature water outlet without replacing the filter element, thereby reducing costs.

[0014] Preferably, an electromagnetic direction-changing valve is provided on the direction-changing pipeline.

[0015] In this solution, in addition to setting up the first pipeline and the second pipeline, only one pipeline can be set, that is, an electromagnetic reversing valve can be set on the reversing pipeline, which can also achieve the effect of two pipelines, simplify the pipelines, reduce water storage and dead water areas in the pipelines, reduce bacterial growth, and make it easier for users to operate.

[0016] Preferably, when the flow rate of the normal temperature water outlet is insufficient, the electromagnetic reversing valve changes the water delivery direction so that the pressure barrel supplies water to the normal temperature water outlet.

[0017] In this solution, when the flow attenuation of the purification component is relatively large or the purification component is blocked, the water supply direction is changed by the electromagnetic reversing valve, thereby restoring the water supply from the pressure barrel to the normal temperature water outlet, ensuring the water flow rate of the normal temperature water outlet.

[0018] Preferably, the water supply system of the water purifier further comprises an ultraviolet sterilization lamp, and the ultraviolet sterilization lamp is arranged between the purification component and the normal temperature water outlet.

[0019] In this solution, the ultraviolet sterilization lamp can further sterilize the water purified by the purification component. The water sterilized by the ultraviolet sterilization lamp is input into the pressure barrel for storage or directly output through the normal temperature water outlet, reducing the bacterial content in the outlet water.

[0020] Preferably, the internal components of the water supply system of the water purifier can be connected by quick-connect connectors.

[0021] In this solution, quick-connect connectors are used to connect the internal components of the water supply system of the water purifier. Since the quick-connect connectors are very short, dead water between pipes can be reduced to avoid bacterial growth.

[0022] Preferably, the water supply system of the water purifier is provided with a plurality of solenoid valves, and the plurality of solenoid valves are closed to form a closed pipeline, and a flushing solenoid valve is provided in the closed pipeline.

[0023] In this solution, the water supply system of the water purifier also has an internal pipeline self-cleaning function. Multiple solenoid valves are closed to form a closed pipeline, and the flushing solenoid valve is opened to allow the water in the pressure barrel to circulate and flush, thereby removing bacteria that grow in the pipeline.

[0024] Preferably, the water purifier water supply system also includes an electronic control device. When the electronic control device detects that the water purifier water supply system has not been working within a preset time, the plurality of solenoid valves are closed to form the closed pipeline, and the flushing solenoid valve is opened to circulate the water in the pressure barrel for flushing.

[0025] In this solution, the electronic control device is used to control the self-cleaning function of the internal pipeline. When the electronic control device detects that the water supply system of the water purifier has not been working within the preset time, a large number of bacteria have grown in the pipeline. By closing multiple solenoid valves to form a closed pipeline, the flushing solenoid valve is opened to allow the water in the pressure barrel to circulate and flush. The electronic control device is set to make flushing smarter.

[0026] The present invention further provides an electromagnetic directional control valve, the electromagnetic directional control valve comprising a first outlet, a second outlet and a one-way channel, the one-way channel connecting the first outlet and the second outlet, and an opening and closing member being arranged in the one-way channel;

[0027] When the water flow in the electromagnetic directional control valve flows from the first outlet to the second outlet, the opening and closing member opens to open the one-way passage;

[0028] When the water in the electromagnetic directional control valve flows from the second outlet to the first outlet, the opening and closing member is closed to close the one-way passage.

[0029] In the present embodiment, a one-way channel is provided in the electromagnetic reversing valve, and an opening and closing member is provided in the one-way channel. When water in the electromagnetic reversing valve flows from the first outlet to the second outlet, the opening and closing member opens to open the one-way channel, and water can flow through. When water in the electromagnetic reversing valve flows in the opposite direction, that is, from the second outlet to the first outlet, the opening and closing member closes to close the one-way channel, and water cannot flow through, so that the water in the one-way channel can only flow in one direction.

[0030] Preferably, the opening and closing member is a sealing ball, and the sealing ball can slide along the one-way channel;

[0031] When the water flow in the electromagnetic reversing valve flows from the first outlet to the second outlet, the water flow pushes the sealing ball to open the one-way channel;

[0032] When the water in the electromagnetic reversing valve flows from the second outlet to the first outlet, the sealing ball seals the first outlet to close the one-way passage.

[0033] In this solution, the opening and closing part is a sealing ball, which slides in the one-way channel to open and close the one-way channel. When the water flow in the electromagnetic reversing valve flows from the first outlet to the second outlet, the sealing ball can open the one-way channel, and when the water flow flows in the opposite direction, the sealing ball can close the one-way channel, thereby realizing the one-way flow of water in the one-way channel.

[0034] Preferably, the one-way channel extends in a vertical direction, and the sealing ball can slide in the vertical direction.

[0035] In this solution, the one-way channel extends in the vertical direction, and the sealing ball can slide in the vertical direction, so that gravity can be better utilized to make the sealing ball close the one-way channel.

[0036] Preferably, the electromagnetic directional control valve further includes a bidirectional channel, wherein the bidirectional channel connects the first outlet and the second outlet;

[0037] An electromagnetic component is provided on the bidirectional channel, and the electromagnetic component controls the opening and closing of the bidirectional channel.

[0038] In this solution, the electromagnetic reversing valve is provided with a two-way channel in addition to a one-way channel. An electromagnetic component is provided on the two-way channel, and the opening and closing of the two-way channel is controlled by the electromagnetic component. Therefore, when water needs to flow in both directions, the two-way channel can be opened to enable water to flow in both directions.

[0039] Preferably, the bidirectional channel includes a communicating hole, and the electromagnetic component includes a blocking component, and the blocking component can close the communicating hole.

[0040] In this solution, the opening and closing of the two-way channel is achieved through the connecting hole and the blocking piece. The blocking piece can block the connecting hole. The blocking piece blocks the connecting hole to close the two-way channel, and the blocking piece is opened to connect the two-way channel.

[0041] Preferably, the electromagnetic component further comprises a moving component, the moving component is capable of sliding, and the blocking component is arranged at one end of the moving component close to the communicating hole.

[0042] In this solution, the opening and closing of the blocking member is achieved by the sliding of the moving member, and the moving member slides to move the blocking member to the communicating hole, thereby closing the communicating hole and closing the two-way channel.

The normal temperature water purified by the purification component is directly output through the normal temperature water outlet, avoiding the problem of excessive bacteria caused by long-term storage of water in the pressure barrel. In other words, the water stored in the pressure barrel only supplies water to the hot water tank, which is heated and sterilized by the hot water tank and then outputs hot water. The normal temperature water purified by the purification component directly supplies normal temperature water, thereby avoiding the problem of bacterial growth in the pressure barrel. In addition, when the flow rate of the normal temperature water outlet is insufficient, the reversing pipeline can change the water outlet direction, so that the water in the pressure barrel can be used to supplement the flow rate of the normal temperature water outlet.

[0083] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the following examples.

[0084] Example 1

[0085] like Figure 1 As shown, this embodiment provides a water purifier water supply system, which includes a pressure barrel 100, a purification component, a hot water tank 300, a normal temperature water outlet 410 and a hot water outlet 420, and the purification component includes a pre-filter element 210, a post-filter element 220, a filter membrane 230 and a water pump 240.

[0086] The water purified by the purification component is stored in the pressure barrel 100. The water in the pressure barrel 100 is used to be input into the hot water tank 300. The hot water tank 300 is used to heat the water input into the pressure barrel 100. The hot water tank 300 is connected to the hot water outlet 420. The hot water outlet 420 is used to output the hot water heated by the hot water tank 300. The normal temperature water outlet 410 is directly connected to the purification component. The normal temperature water outlet 410 is used to directly output the normal temperature water purified by the filter component. A change-direction pipeline 500 is provided between the pressure barrel 100 and the normal temperature water outlet 410. The change-direction pipeline 500 can change the water delivery direction.

[0087] The water purified by the purification component is stored in the pressure barrel 100, and then input into the hot water tank 300 for heating, and the heated water is output from the hot water outlet 420. The normal temperature water purified by the purification component is directly output through the normal temperature outlet 410, avoiding the problem of excessive bacteria caused by long-term storage of water in the pressure barrel 100. In other words, the water stored in the pressure barrel 100 only supplies water to the hot water tank 300, and is heated and sterilized by the hot water tank 300 before outputting hot water. The normal temperature water purified by the purification component directly supplies normal temperature water, thereby avoiding the problem of bacterial growth in the pressure barrel 100. In addition, when the flow rate of the normal temperature outlet 410 is insufficient, the direction-changing pipeline 500 can change the water outlet direction, so that the water in the pressure barrel 100 can be used to supplement the flow rate of the normal temperature outlet 410.

[0088] In this embodiment, the direction-changing pipeline 500 includes a first pipeline 510 and a second pipeline 520. The first pipeline 510 connects the pressure barrel 100 with the purification component. The first pipeline 510 is provided with a one-way valve 511 and a high-pressure switch 512 for flowing from the purification component to the pressure barrel 100, so that the water purified by the purification component can be input into the pressure barrel 100, but the water in the pressure barrel 100 cannot flow into the normal temperature water outlet 410 through the first pipeline 510, so that the water in the pressure barrel 100 can only supply water to the hot water tank 300. The second pipeline 520 connects the pressure barrel 100 with the normal temperature water outlet 410. The second pipeline 520 is provided with a manual ball valve 521. Opening the manual ball valve 521 can restore the water supply from the pressure barrel 100 to the normal temperature water outlet 410.

[0089] When the flow rate of the normal temperature water outlet 410 is insufficient, that is, when the flow rate of the purification component is greatly attenuated or the purification component is blocked, the manual ball valve 521 is opened to allow the pressure barrel 100 to supply water to the normal temperature water outlet 410, thereby ensuring the water flow rate of the normal temperature water outlet 410, and making it unnecessary to replace the filter element of the water purifier, thereby reducing costs.

[0090] The water supply system of the water purifier also includes an ultraviolet sterilization lamp 600, which is arranged between the purification component and the normal temperature water outlet 410. The ultraviolet sterilization lamp 600 can further sterilize the water purified by the purification component. The water sterilized by the ultraviolet sterilization lamp 600 is input into the pressure barrel 100 for storage or directly output through the normal temperature water outlet 410, reducing the bacterial content in the outlet water.

[0091] The internal components of the water supply system of the water purifier can be connected by quick-connect fittings. Since the quick-connect fittings are very short, the dead water between the pipes can be reduced to prevent bacteria from growing. For example, the ultraviolet sterilization lamp 600 and the normal temperature water solenoid valve ensure that there is no dead water at the normal temperature water outlet solenoid valve 740. The hot water tank inlet solenoid valve 720 is connected to the one-way valve 511 and the pressure barrel 100 pipeline, and quick-connect fittings are also used to prevent the dead water at the hot water tank inlet solenoid valve 720.

[0092] The water supply system of the water purifier is provided with a plurality of solenoid valves, which are closed to form a closed pipeline, and a flushing solenoid valve 750 is provided in the closed pipeline. The water supply system of the water purifier also has an internal pipeline self-cleaning function, and a plurality of solenoid valves are closed to form a closed pipeline, and the flushing solenoid valve 750 is opened so that the water in the pressure barrel 100 can be circulated and flushed, and purified by the filter membrane 230 to remove bacteria growing in the pipeline. The plurality of solenoid valves include a total water inlet solenoid valve 710, a hot water tank inlet solenoid valve 720, a hot water tank outlet solenoid valve 730, a normal temperature water outlet solenoid valve 740, a flushing solenoid valve 750, a waste water solenoid valve 760, a drainage solenoid valve 770, etc.

[0093] The water supply system of the water purifier also includes an electronic control device. When the electronic control device detects that the water supply system of the water purifier has not been working within a preset time, multiple solenoid valves are closed to form a closed pipeline, and the flushing solenoid valve 750 is opened to circulate the water in the pressure barrel 100 for flushing.

[0094] The electronic control device is used to control the self-cleaning function of the internal pipeline. When the electronic control device detects that the water supply system of the water purifier has not been working within the preset time, a large number of bacteria have grown in the pipeline. By closing multiple solenoid valves to form a closed pipeline, the flushing solenoid valve 750 is opened to allow the water in the pressure barrel 100 to circulate and flush. The electronic control device is set to make flushing more intelligent.

[0095] Example 2

[0096] The structure of this embodiment is basically the same as that of Embodiment 1, and the same structure will not be described in detail. The difference is that:

[0097] like Figure 2 As shown, in this embodiment, a pipeline is provided to replace the first pipeline 510 and the second pipeline 520, and an electromagnetic reversing valve 800 is provided on the reversing pipeline 500. The water flow direction is changed by opening and closing the electromagnetic reversing valve 800, thereby streamlining the pipeline, reducing water storage and dead water areas in the pipeline, reducing bacterial growth, and making it easier for users to operate.

[0098] When the flow rate of the normal temperature water outlet 410 is insufficient, the electromagnetic reversing valve 800 changes the water delivery direction so that the pressure barrel 100 supplies water to the normal temperature water outlet 410. In other words, when the flow rate of the purification component is greatly attenuated or the purification component is blocked, the electromagnetic reversing valve 800 changes the water delivery direction, thereby restoring the water supply of the pressure barrel 100 to the normal temperature water outlet 410, and ensuring the water flow rate of the normal temperature water outlet 410.

[0099] like Figure 3 and Figure 4 As shown, this embodiment provides a specific structure of an electromagnetic direction-changing valve 800, wherein the electromagnetic direction-changing valve 800 includes a first outlet 810, a second outlet 820, and a one-way channel 830, wherein the one-way channel 830 connects the first outlet 810 and the second outlet 820, and an opening and closing member 840 is provided in the one-way channel 830. When the water flow in the electromagnetic direction-changing valve 800 flows from the first outlet 810 to the second outlet 820, the opening and closing member 840 opens to open the one-way channel 830. When the water flow in the electromagnetic direction-changing valve 800 flows from the second outlet 820 to the first outlet 810, the opening and closing member 840 closes to close the one-way channel 830.

[0100] A one-way channel 830 is provided in the electromagnetic reversing valve 800, and an opening and closing member 840 is provided in the one-way channel 830. When water in the electromagnetic reversing valve 800 flows from the first outlet 810 to the second outlet 820, the opening and closing member 840 opens to open the one-way channel 830, and water can flow through. When water in the electromagnetic reversing valve 800 flows in the opposite direction, that is, from the second outlet 820 to the first outlet 810, the opening and closing member 840 closes to close the one-way channel 830, and water cannot flow through, so that the water in the one-way channel 830 can only flow in one direction.

[0101] In this embodiment, the opening and closing member 840 is a sealing ball 841, and the sealing ball 841 can slide along the one-way channel 830. When the water flow in the electromagnetic reversing valve 800 flows from the first outlet 810 to the second outlet 820, the water flow pushes the sealing ball 841 to open the one-way channel 830. When the water flow in the electromagnetic reversing valve 800 flows from the second outlet 820 to the first outlet 810, the sealing ball 841 closes the first outlet 810 to close the one-way channel 830. The sliding of the sealing ball 841 in the one-way channel 830 can achieve the effect of opening and closing the one-way channel 830. When the water flow in the electromagnetic reversing valve 800 flows from the first outlet 810 to the second outlet 820, the sealing ball 841 can open the one-way channel 830, and when the water flow flows in the reverse direction, the sealing ball 841 can close the one-way channel 830, thereby realizing the one-way flow of the water flow in the one-way channel 830. In other embodiments, the opening and closing member 840 may also have other structures that are considered appropriate by those skilled in the art.

[0102] In this embodiment, the one-way channel 830 extends in the vertical direction, and the sealing ball 841 can slide in the vertical direction, so that gravity can be better used to make the sealing ball 841 close the one-way channel 830. In other embodiments, other extension directions of the one-way channel 830 that are considered appropriate by those skilled in the art can also be selected.

[0103] The electromagnetic reversing valve 800 further includes a two-way channel 850, which communicates with the first outlet 810 and the second outlet 820. The two-way channel 850 is provided with an electromagnetic component 860, which controls the opening and closing of the two-way channel 850, so that when the water flow needs to flow in both directions, the two-way channel 850 can be opened to enable the water flow to flow in both directions.

[0104] The two-way channel 850 includes a connecting hole 851, and the electromagnetic component 860 includes a blocking component 861. The opening and closing of the two-way channel 850 is achieved through the connecting hole 851 and the blocking component 861. The blocking component 861 can close the connecting hole 851. The blocking component 861 closes the connecting hole 851 to close the two-way channel 850, and the blocking component 861 is opened to connect the two-way channel 850.

[0105] In this embodiment, the blocking member 861 is a sealing gasket. In other embodiments, other specific structures of the blocking member 861 that are considered appropriate by those skilled in the art may also be selected.

[0106] The electromagnetic member 860 further includes a moving member 862, which is capable of sliding, and a blocking member 861 is disposed at one end of the moving member 862 close to the connecting hole 851. The opening and closing of the blocking member 861 is achieved by the sliding of the moving member 862, and the moving member 862 slides to move the blocking member 861 onto the connecting hole 851, thereby closing the connecting hole 851 and closing the two-way channel 850.

[0107] In the present embodiment, the moving member 862 is an armature, and the armature is moved by the control of a spring and an electromagnetic coil. In other embodiments, other specific structures of the moving member 862 that are considered suitable by those skilled in the art may also be selected.

[0108] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
