Description

Technical Field

[0001] This application relates to the field of water purification system technology, and in particular to water purifiers. Background Technology

[0002] With the development of water purification system technology, water purifiers are being used more and more widely in people's lives, and people's requirements for the convenience of water use are also increasing.

[0003] In related technologies, water purifiers can only obtain water from tap water or from a water storage tank, resulting in a limited water source and scope of application. Furthermore, these water purifiers can only produce room temperature or warm water, limiting their functionality. Utility Model Content

[0004] Therefore, it is necessary to provide a water purifier to address the problems of limited water source availability, limited applicability, and limited functionality.

[0005] The water purifier includes:

[0006] The first water supply line includes a water inlet;

[0007] The second water supply line includes a raw water tank, which is configured to store raw water.

[0008] A water intake component, which is connected to the outside world, is configured to selectively draw water from the first water supply line or the second water supply line;

[0009] The instant hot water circuit has one end connected to the first water supply circuit and the second water supply circuit, and the other end connected to the water intake component. The instant hot water circuit is configured to provide room temperature water and warm water to the water intake component.

[0010] A cold water circuit, one end of which is connected to the first water supply circuit and the second water supply circuit, and the other end of which is connected to the water intake component, wherein the cold water circuit is configured to provide cold water to the water intake component;

[0011] The water intake component can be selectively connected to at least one of the instant hot water circuit and the cold water circuit.

[0012] Users can choose to use either the raw water tank or the water from the inlet as their water source, allowing them to select from different sources and thus expanding the applicability of the water purifier. Furthermore, the water purifier supplies three different types of water: room temperature water, warm water, and ice water, further catering to diverse user needs.

[0013] In one embodiment, the first water supply path further includes:

[0014] A water storage tank is connected between the water supply end and the water inlet of the instant hot water circuit via a pipeline. The water storage tank is configured to store the water supplied by the water inlet so that the user can draw water from the water storage tank. This helps to ensure the stability of the water supply flow and allows the instant hot water circuit to stably control the water temperature when the user draws warm water, thereby improving the user experience.

[0015] In one embodiment, the water tank is fixed inside the water purifier, which helps reduce the overall size of the water purifier. At the same time, fixing the water tank inside the water purifier helps protect the water tank from the outer casing, and also simplifies the structure and reduces costs.

[0016] And / or, the raw water tank is detachable and is configured to be filled with raw water in a detached state, so that the user can remove it and replenish the raw water tank with raw water.

[0017] In one embodiment, the second water supply path further includes:

[0018] A filter element is disposed in the raw water tank, and the filter element is configured to filter liquid from the raw water tank.

[0019] In this design, the filter cartridge does not occupy separate space, which helps to reduce the size of the water purifier. Since the filter cartridge is located in the raw water tank, the water purifier does not need to be equipped with an additional booster pump to supply water, which helps to further reduce the size of the water purifier and also helps to reduce costs.

[0020] In one embodiment, the water purifier further includes:

[0021] The first connecting valve has a first interface, a second interface, and a third interface. The first interface is connected to the first water supply circuit, the second interface is connected to the second water supply circuit, and the water intake component is connected to the third interface.

[0022] The first connecting valve can combine the water flow from the first water supply circuit and the second water supply circuit into a single outlet water circuit, which helps to simplify the water circuit structure.

[0023] In one embodiment, the water purifier further includes:

[0024] The pump motor has one end connected to the third interface and the other end connected to the inlet of both the instant hot water circuit and the cold water circuit. The voltage and flow rate of the pump motor are adjustable, which allows for reasonable control of the water supply flow to the instant hot water circuit based on the user-set water temperature at the water intake component, thus ensuring the accuracy of the instant hot water outlet temperature and improving the user experience. Furthermore, since both the storage tank and the raw water tank contain water, the water intake component only needs to draw water directly from the storage tank using the pump motor, eliminating the need for a booster pump and saving energy.

[0025] In one embodiment, the instant hot water circuit includes:

[0026] The instant heating component is connected to the outlet of the pump motor; and

[0027] The water-air separation box is connected at both ends to the instant heating component and the water intake component, respectively.

[0028] This instant hot water circuit uses an instant heating component to heat the water flow, so that warm water of the corresponding temperature can be supplied to the water intake component. The water-gas separator is used to remove the gas generated by the instant heating component when heating water, thereby protecting the safety of the instant heating component.

[0029] In one embodiment, the water purifier further includes:

[0030] A sparkling water path, which is configured to provide sparkling water.

[0031] In addition to producing room temperature water, warm water, and ice water, this water purifier can also provide sparkling water, which helps to further meet the different water needs of users.

[0032] In one embodiment, the cold water circuit has a cold water tank, which is connected to the water intake component and the inlet of the sparkling water circuit, respectively. This allows the sparkling water circuit and the cold water circuit to share the same cold water tank, which helps to simplify the water circuit structure of the water purifier, reduce its size, and save costs.

[0033] In one embodiment, the water purifier further includes:

[0034] The second connecting valve has a fourth interface, a fifth interface, and a sixth interface. The fourth interface is connected to the third interface, the fifth interface is connected to the instant hot water circuit, and the sixth interface is connected to the cold water circuit.

[0035] The second connecting valve diverts the water from the first connecting valve to different water paths, which helps to simplify the water path structure, reduce volume, and save costs. Attached Figure Description

[0051] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0052] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0053] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0057] Figure 1 A schematic diagram of the water circuit principle of a water purifier provided in one embodiment of this application is shown; Figure 2 A schematic diagram of the water flow direction of a water purifier provided in one embodiment of this application is shown.

[0058] like Figure 1 and Figure 2 As shown, the water purifier includes a first water supply circuit 100, a second water supply circuit 200, and a water intake component 400.

[0059] The first water supply line 100 includes an inlet 110, which can be connected to the municipal water supply network, a user's faucet, etc., through a pipe to obtain tap water. In some embodiments, the inlet 110 can also be connected to a household water purification system to obtain purified water that has been treated by the system, so that users can drink it directly and improve user safety.

[0060] The first water supply circuit 100 also includes a water storage tank 120, which is configured to store the water supplied by the inlet 110 so that users can directly access the water when they need it. When users take water, they are supplied from the water storage tank 120, which helps to ensure the stability of the water supply flow.

[0061] The water tank 120 is fixed inside the water purifier, which helps to reduce the overall size of the water purifier. At the same time, fixing the water tank 120 inside the water purifier helps to protect the water tank 120 from the outer shell, and also helps to simplify the structure and reduce costs.

[0062] The first water supply circuit 100 also includes a three-way valve 140 and a third connecting valve 150 connected sequentially between the water inlet 110 and the water storage tank 120 via pipelines. The third connecting valve 150 is a solenoid valve.

[0063] In one embodiment, such as Figure 1 and Figure 2 As shown, the second water supply circuit 200 includes a raw water tank 210, which is configured to store raw water. Normally, the raw water in the raw water tank 210 is tap water, bottled water, or well water that the user manually draws. The user can inject the corresponding amount of raw water into the raw water tank 210 as needed.

[0064] The raw water tank 210 can be detachable, and is configured to be filled with raw water in a detached state, so that users can remove it and replenish the raw water tank 210 with raw water. In order to facilitate users to fill the raw water tank 210 with raw water, users can also be provided with a water inlet, through which users can fill the raw water tank 210 with water.

[0065] In addition, the second water supply circuit 200 also includes a filter element 220, which is installed in the raw water tank 210 and is used to filter the liquid from the raw water tank 210. In this design, the filter element 220 does not occupy separate space, which helps to reduce the size of the water purifier. Since the filter element 220 is located in the raw water tank 210, the water purifier does not need to be equipped with an additional booster pump to supply water, which helps to further reduce the size of the water purifier and also helps to reduce costs.

[0066] The filter element 220 can be a filter element 220 such as activated carbon filter element 220, PP filter element 220, ceramic filter element 220, resin filter element 220, etc., as well as a composite filter element 220 composed of one or more of these filter elements 220.

[0067] The water purifier also includes a first connecting valve 300, which has a first interface 310, a second interface 320, and a third interface 330. The first interface 310 is connected to the first water supply circuit 100, the second interface 320 is connected to the second water supply circuit 200, and the water intake component 400 is connected to the third interface 330. The water intake component 400 is connected to the outside environment and is configured to selectively connect to either the first water supply circuit 100 or the second water supply circuit 200. Users can choose to use the raw water tank 210 or the water from the inlet 110 as a water source according to their water needs, which helps to meet the needs of users to choose different water sources and expands the applicability of the water purifier.

[0068] For example, when the user's installation environment has both a tap water supply system or a water purification system (first water supply line 100) and a raw water tank 210 (second water supply line 200), the user can connect to both water sources simultaneously and choose which to use. When the user's installation environment cannot connect to a tap water supply system or a water purification system, the user can only use the raw water tank 210. Conversely, when the user's installation environment can connect to a tap water supply system or a water purification system, the user can choose not to use the raw water tank 210.

[0069] In one embodiment, such as Figure 1 and Figure 2 As shown, the first connecting valve 300 is a two-position three-way valve, which is an electrically controlled switch and also a type of solenoid valve. The two-position three-way valve can quickly switch the flow direction or on / off state of liquid between the three ports based on an electrical signal.

[0070] In addition, the water purifier connects the two water sources, the first water supply path 100 and the second water supply path 200, through the first connecting valve 300 to the downstream, which helps to simplify the water path connection structure in the water purifier.

[0071] In addition, such as Figures 1 to 3 As shown, the water purifier also includes a control component 600, which is electrically connected to the first connecting valve 300. The control component 600 controls the first connecting valve 300 to connect with either the first water supply circuit 100 or the second water supply circuit 200, thereby controlling the water dispensing component 400 to obtain water supplied by either the first water supply circuit 100 or the second water supply circuit 200. When the user's installation environment allows connection to both tap water and a water purification system, and also allows access to the raw water tank 210, the user can use the control component 600 to select whether to draw water from the first water supply circuit 100 or the second water supply circuit 200 to meet different water usage needs. This water purifier helps to further improve the user experience.

[0072] In one embodiment, such as Figure 3 As shown, a control panel 1100 is installed at the water outlet of the water purifier. The control panel 1100 is electrically connected to the control component 600. The control panel 1100 has two modes that can be selected to connect to the first water supply circuit 100 or the second water supply circuit 200. Users can make the appropriate selection according to their needs.

[0073] The water purifier also includes a water pump motor 500. One end of the water pump motor 500 is connected to the third interface 330, and the other end is connected to the inlet of the instant hot water circuit 700. The voltage and flow rate of the water pump motor 500 are adjustable, which helps to reasonably control the water supply flow to the instant hot water circuit 700 according to the water temperature set by the user at the water dispensing component 400, thereby ensuring the accuracy of the water temperature output from the instant hot water circuit 700 and improving the user experience. At the same time, since both the storage tank 120 and the raw water tank 210 contain water, the water dispensing component 400 only needs to draw water directly from the storage tank through the water pump motor 500 for use, eliminating the need for a booster pump and saving energy.

[0074] The water purifier also includes an instant hot water circuit 700. One end of the instant hot water circuit 700 is connected to the first water supply circuit 100 and the second water supply circuit 200, and the other end is connected to the water dispensing component 400. The instant hot water circuit 700 is used to provide room temperature water and warm water to the water dispensing component 400 to meet the user's different water needs. A water storage tank 120 is connected between the water supply end and the water inlet 110 of the instant hot water circuit 700 via a pipe, so that when the user dispenses warm water, the instant hot water circuit 700 can stably control the water flow and thus the water temperature, improving the user experience.

[0075] Furthermore, the instant hot water circuit 700 includes an instant heating element 710 and a water vapor separator 720. The instant heating element 710 is connected to the outlet of the water pump 500, and the two ends of the water vapor separator 720 are connected to the instant heating element 710 and the water intake element 400, respectively. This instant hot water circuit 700 uses the instant heating element 710 to heat the water flow, so as to supply warm water of the corresponding temperature to the water intake element 400. The water vapor separator 720 is used to discharge the gas generated by the instant heating element 710 when heating water, thereby protecting the safety of the instant heating element 710.

[0076] When in operation, the instant heating component 710 operates when the water intake component 400 is connected to the instant hot water circuit 700, allowing the user to obtain room temperature or hot water from the water intake component 400. The instant heating component 710 can be an instant heating element, etc.

[0077] When the user selects room temperature water, the instant heating element 710 does not work. When the user selects hot water, the instant heating element 710 works.

[0078] The water purifier also includes a cold water circuit 800. One end of the cold water circuit 800 is connected to the first water supply circuit 100 and the second water supply circuit 200, and the other end is connected to the water intake component 400. The cold water circuit 800 is used to provide cold water to the water intake component 400. Based on room temperature water and warm water, the water purifier can meet the user's various water needs for room temperature water, warm water and cold water.

[0079] Furthermore, the water intake component 400 can be connected to at least one of the instant hot water circuit 700 and the cold water circuit 800, so that the user can choose to take one type of water, or take room temperature water and ice water at the same time, or take warm water and ice water at the same time.

[0080] like Figure 1 and Figure 2 As shown, in one embodiment, the water purifier also includes a sparkling water path 900 for providing sparkling water. In addition to producing room temperature water, warm water, and ice water, this water purifier can also provide sparkling water, further meeting the diverse water needs of users.

[0081] The cold water circuit 800 has a cold water tank 831, which is connected to the water intake component 400 and the inlet 910 of the sparkling water circuit 900. This allows the sparkling water circuit 900 and the cold water circuit 800 to share the cold water tank 831, which simplifies the water circuit structure of the water purifier, reduces its size, and saves costs.

[0082] Specifically, between the cold water tank 831 and the water intake component 400, the cold water circuit 800 is provided with a first outlet 810, which has two outlet branches. One branch is connected to the water intake component 400 so that the water intake component 400 can take ice water. The other branch is connected to the inlet 910 of the sparkling water circuit 900 so that the sparkling water circuit 900 can use the cold water from the cold water circuit 800 to produce sparkling water, which helps to simplify the water circuit structure of the water purifier.

[0083] The water purifier also includes a second connecting valve 1000, which has a fourth port 1001, a fifth port 1002, and a sixth port 1003. The fourth port 1001 is connected to the third port 330, the fifth port 1002 is connected to the instant hot water circuit 700, and the sixth port 1003 is connected to the cold water circuit 800. The second connecting valve 1000 diverts water from the first connecting valve 300 to different water circuits, which helps to simplify the water circuit structure, reduce size, and save costs.

[0084] In one embodiment, such as Figure 1 and Figure 2 As shown, the second connecting valve 1000 can be a two-position three-way valve. A two-position three-way valve is an electrically controlled switch, and also a type of solenoid valve. The two-position three-way valve can quickly switch the flow direction or on / off state of liquid between the three ports based on an electrical signal.

[0085] The second connecting valve 1000 is electrically connected to the control component 600 to control the energization or de-energization of the solenoid valve coil in the second connecting valve 1000.

[0086] The chilled water circuit 800 includes a refrigeration assembly 830, which is used to cool the water supplied from the pump motor 500. The refrigeration assembly 830 includes a chilled water tank 831, a condenser 832, a compressor 833, and an evaporator 834. The condenser 832 and the compressor 833 cool the water in the chilled water tank 831 by heating and pressurizing the refrigerant at the chilled water tank 831.

[0087] The cold water circuit 800 also includes a booster pump 840, a first check valve 850, a cold water solenoid valve 860, and a second check valve 870, which are connected in sequence to the outlet of the cold water tank 831 via pipelines. The second check valve 870 is connected to the water intake assembly 400. When the water intake assembly 400 is connected to the cold water circuit 800, the user can obtain cold water at the water intake assembly 400.

[0088] The first outlet 810 mentioned above is located between the first check valve 850 and the cold water solenoid valve 860.

[0089] The sparkling water circuit 900 includes a third one-way valve 920, a carbonation tank 930, a flow restrictor 940, and a sparkling water solenoid valve 950, which are sequentially connected to the second outlet 820, and then connected to the water intake assembly 400. Additionally, the sparkling water gas circuit includes a carbon dioxide cylinder 960, a high-pressure switch 970, a fourth one-way valve 980, and a pressure relief valve 990, arranged sequentially.

[0090] When a user wants sparkling water, they can get it directly from the water dispensing component 400.

[0091] To facilitate users in obtaining different types of water, the water dispensing assembly 400 has a third outlet 410 and a fourth outlet 420. The third outlet 410 can be used to dispense room temperature water or hot water, and the fourth outlet 420 can be used to dispense cold water or sparkling water.

[0092] It is worth noting that the "connection" in this embodiment can be a direct connection or an indirect connection, and this embodiment does not limit it.

[0093] All valve structures in this embodiment can be electrically connected to the control module to precisely control the water circuit connection status and improve the user experience.

[0094] In summary, the water purifier in this embodiment has a first water supply path 100 and a second water supply path 200 at the water supply end, and an instant hot water path 700, a cold water path 800 and a sparkling water path 900 at the water outlet end.

[0095] In the first water supply circuit 100, water flows from the inlet 110 through the three-way valve 140, the third connecting valve 150, the water storage tank 120, the first connecting valve 300, and the pumping motor 500. In the second water supply circuit 200, water flows through the raw water tank 210, the filter element 220, the first connecting valve 300, and the pumping motor 500.

[0096] When drawing room temperature or hot water, the water is drawn by the pump motor 500 and then flows sequentially through the second connecting valve 1000, the instant heating component 710, the water-air separator 720, and the third outlet 410. The third outlet 410 can dispense room temperature or hot water according to the user's needs. When the water intake component 400 is connected to the instant hot water circuit 700, the instant heating component 710 is operational, and the user can obtain room temperature or hot water from the water intake component 400. When the user selects room temperature water, the instant heating component 710 is not operational. When the user selects hot water, the instant heating component 710 is operational.

[0097] When cold water is drawn, the water is drawn by the pumping motor 500, and then flows sequentially through the second connecting valve 1000, the cold water tank 831, the booster pump 840, the first check valve 850, the cold water solenoid valve 860, the second check valve 870, and the fourth outlet 420, and then the cold water is discharged from the fourth outlet 420.

[0098] When taking out sparkling water, the water in the cold water tank 831 passes through the booster pump 840, the first one-way valve 850, the third one-way valve 920, and enters the carbonation tank 930. The sparkling water's gas path passes sequentially through the carbon dioxide cylinder 960, the high-pressure switch 970, the fourth one-way valve 980, the pressure relief valve 990, and the carbonation tank 930. That is, both cold water and bubbles are injected into the carbonation tank 930. Then, the pressure in the carbonation tank 930 increases, causing the sparkling water to flow sequentially through the flow-limiting connector 940, the sparkling water solenoid valve 950, and the fourth outlet 420, and then exit from the fourth outlet 420.

[0099] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0100] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application.
