Description

Technical Field

[0001] The invention relates to the technical field of water purifiers, in particular to an embedded water purifier. Background Art

[0002] A water purifier, also called a water purifier or water filter, is a water treatment device that deeply filters and purifies water according to the requirements for water use. Its technical core is the filter membrane in the filter element device. Currently, the main technologies come from ultrafiltration membrane and reverse osmosis membrane. Through various filtration and adsorption units, it can effectively filter out rust, bacteria, sand, heavy metals, colloids in water, and adsorb residual chlorine, odor, discoloration, pesticides and other chemical agents in water. The application of water purification technology in the field of drinking water will make the phenomenon of "water and soil incompatibility" a thing of the past soon, and effectively solve the endemic diseases caused by excessive harmful minerals in groundwater in many places.

[0003] A stand-alone water purifier takes up space, while an embedded water dispenser is reasonably and cleverly designed to be embedded in a wall, kitchen countertop or cabinet, which can effectively save space and has a beautiful appearance, in line with the design concept of modern architecture and home. An embedded water dispenser usually has functions such as automatic water supply, purification and filtration, which can meet people's usage needs.

[0004] For example, an embedded water purifier disclosed in Chinese patent document CN202831069U includes a water purifier body, which is provided with a total water inlet and a total water outlet.

A main water pipe and a purified water supply pipe are preset in the water purifier installation groove. The total water inlet is connected to the main water pipe through an inlet pipe, and the total water outlet is connected to the purified water supply pipe through an outlet pipe. The purified water supply pipe is connected to each water end. Figures 1 to 3 It can be seen that the patent solution has a total water inlet, a total water outlet and a total sewage outlet. Such a setting will make the use scenario of the embedded water purifier relatively single and cannot meet the use needs of contemporary people.

[0034] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 15 An embedded water purifier shown includes an outer shell 1, wherein the outer shell 1 is provided with an installation cavity 2, a filter assembly 3 located on the installation cavity 2, an interactive assembly 4, a drinking water outlet 5 connected to the pure water end of the filter assembly 3, a raw water inlet 6 connected to the raw water end of the filter assembly 3, a domestic water outlet 7 connected to the pure water end of the filter assembly 3, and a waste water outlet 8 connected to the waste water end of the filter assembly 3 are provided at the back or side of the outer shell 1, and the drinking water outlet 5 includes a normal temperature water outlet 51 connected to the outlet end of the filter assembly 3, and a warm water outlet 52. The present invention can improve the intelligence, convenience of use, and energy-saving and environmental protection performance of the product, and bring a more comfortable and healthy life experience to users. The present invention can have more diverse usage scenarios, not only allowing users to perform convenient operations through interactive components, but also enabling users to obtain normal temperature drinking water or warm drinking water through the drinking water outlet, and obtain kitchen water through the domestic water outlet. The raw water inlet, domestic water outlet and waste water outlet are arranged at the back or side of the outer shell, which can ensure that the use function of the embedded water purifier can meet the needs of users without affecting the appearance of the embedded water purifier.

[0036] Furthermore, as a preferred embodiment of the present invention but not a limitation, the provision of the installation cavity not only makes the structure of the water purifier more compact, but also can better protect the filter assembly and other components of the water purifier, and can better accommodate and fix interfaces such as the raw water inlet, domestic water outlet, and wastewater outlet, thereby improving the stability and reliability of the equipment.

[0037] Furthermore, as a preferred embodiment of the present invention but not a limitation, the filter component located on the installation cavity may include core components of water purification technology such as ultrafiltration membranes and reverse osmosis membranes, which can effectively remove impurities, heavy metals, bacteria, viruses and other harmful substances in the water through filtration and adsorption to provide pure drinking water.

[0038] Furthermore, as a preferred embodiment of the present invention but not a limitation, the wastewater outlet connected to the wastewater end of the filter assembly can be used to discharge wastewater to avoid wasting water resources and polluting the environment.

[0039] Furthermore, as a preferred embodiment of the present invention but not a limitation, the domestic water outlet connected to the pure water end of the filter component can be used to provide kitchen water, such as washing dishes, washing vegetables, etc., which is convenient for users to use when cooking, and can also provide domestic purified water for washing face, cleaning, etc.

[0040] Furthermore, as a preferred embodiment of the present invention but not a limitation, the interactive component may provide a more convenient operating interface, and the user can control, monitor and maintain the equipment through the interactive component. The user can understand the working status of the embedded water purifier and set various usage scenarios from the interactive component, thereby meeting the needs of use and further improving the user experience and convenience.

[0041] Optionally, in some embodiments, the interactive component 4 includes a display screen 41, a water temperature display light, and a water collection light. Further, as a preferred embodiment of the present invention but not a limitation, this design can display the operating status, water quality information, working status, parameter adjustment, water temperature and other information of the water purifier through the display screen, so that users can view and understand the real-time situation of the water purifier. The water temperature display light can intuitively display the temperature of the drinking water, so that users can more conveniently obtain water temperature information when collecting water. The water collection light can light up when water is needed to prompt the user to perform the water collection operation.

[0042] Through the design of these interactive components, users can interact with the water purifier more conveniently, obtain relevant information and control the operation of the water purifier. This not only improves the user's convenience, but also enhances the interactivity between the user and the water purifier.

[0043] like Fig.15In the embedded water purifier shown, a mounting groove 11 is provided on the back or side of the outer shell 1, and the mounting groove 11 is located on the lower side of the outer shell 1, and the raw water inlet 6, the domestic water outlet 7, and the waste water outlet 8 are fixed on the mounting groove 11. Further, as a preferred embodiment of the present invention but not a limitation, the mounting groove is located on the lower side of the outer shell, which can make full use of the space and make the water purifier more compact. The design of this configuration may help to facilitate the installation and fixation of the water inlet, outlet and waste water outlet of the water purifier. By setting the mounting groove, these important connecting parts can be fixed at specific positions of the outer shell to ensure their stability and safety. This structural configuration helps to simplify the installation steps, improve the efficiency of the installation work, and facilitate the user to perform maintenance operations.

[0044] Preferably, the mounting groove is located at the rear of the outer shell, and the raw water inlet 6, the domestic water outlet 7, and the waste water outlet 8 are arranged along a straight line. This helps to make the water purifier neat and beautiful.

[0045] like Figure 3 to Figure 4 In the embedded water purifier shown, the installation cavity 2 is provided with a first area 21 and a second area 22 adjacent to the first area 21, the filter assembly 3 at least includes a composite filter element 31 located in the first area 21, and a reverse osmosis filter element 32 located in the second area 22, a booster assembly 33 is arranged between the composite filter element 31 and the reverse osmosis filter element 32, and the composite filter element 31 and the reverse osmosis filter element 32 are arranged symmetrically. By arranging different filter elements in different areas, multi-level water purification can be achieved, various impurities and pollutants in the water can be effectively filtered out, and the water purification effect can be improved. Optionally, in some embodiments, the composite filter element can be used to remove large particles of impurities, suspended matter, etc. in the raw water; the reverse osmosis filter element can be used to further remove harmful substances such as tiny particles, bacteria, viruses, etc. in the raw water. At the same time, the setting of the booster assembly can increase the water flow rate, ensure that the water flows smoothly through each filter assembly, thereby purifying the water more thoroughly and making the filtering process more efficient. Placing different filter elements and booster assemblies in different areas makes the structure of the entire water purifier more compact, and is convenient for maintenance and replacement of filter elements.

[0046] Furthermore, as a preferred embodiment of the present invention but not limiting, the composite filter element in the composite filter element can be used for preliminary filtration and removal of larger particles of impurities, while the composite filter element or the reverse osmosis filter element in the reverse osmosis filter element can further improve the water purification effect. It can provide a more refined and efficient filtering effect for different water needs, so as to meet the water purification requirements of different users.

[0047] The composite filter element and the reverse osmosis filter element are symmetrically arranged, which is conducive to balancing the water flow pressure on both sides, making the operation of the water purifier more stable and efficient, and ensuring that the water quality is fully purified after being processed at different stages. At the same time, the use of composite filter elements or reverse osmosis filter elements can provide more refined and efficient filtering effects for different water needs.

[0048] like Figures 4 to 9 An embedded water purifier is shown, wherein a boiled water module 321 is connected between the water outlet end of the reverse osmosis filter element 32 and the warm water outlet end 52, the boiled water module 321 comprises a heating element 3211, and a cooling component 3212 connected to the water outlet end of the heating element 3111, the cooling component 3212 is arranged on the outside of the heating element 3211 and arranged in a spiral manner.

[0049] Furthermore, as a preferred embodiment of the present invention but not limiting, a boiled water module is connected between the water outlet of the reverse osmosis filter element and the warm and hot water outlet, and the boiled water module can heat part of the hot water to a set temperature through a heating element, and cool the other part of the hot water to a set temperature through a cooling element. In this way, users can choose to drink normal temperature water, warm and hot water, or boiled water according to their needs.

[0050] Further, as a preferred embodiment of the present invention but not a limitation, this design can enable the cooling component to quickly cool the hot water output by the heating element. The cooling component arranged in a spiral shape can increase the contact area between the water flow and the air, thereby accelerating the heat dissipation, so that the hot water can be quickly cooled.

[0051] This design not only improves cooling efficiency, but also ensures the freshness and taste of drinking water. In addition, the cooling component is arranged on the outside of the heating element in a spiral shape. This compact structure facilitates the installation and use of the boiled water module and saves space. It can avoid affecting the heating element and ensure the stability and safety of the water purifier.

[0052] like Figures 4 to 9An embedded water purifier is shown, the mixing valve 3215 is provided with a hot water pipe 32151 and a warm water pipe 32152, the cooling component 3212 includes a spirally arranged outer pipe 32121, an inner pipe 32122 located on the inner side of the outer pipe 32121, and a three-way connector 32123 respectively connected to the water outlet end of the heating element 3211, the inner pipe 32122, and the hot water pipe 32151, a first water channel 32124 is provided between the outer pipe 32121 and the inner pipe 32122, the water inlet end of the first water channel 32124 is connected to the water outlet end of the flow control pump 3214, and the water outlet end of the first water channel 32124 is connected to the water inlet end of the heating element 3211, the water inlet end of the inner pipe 32122 is communicated with the three-way connector 32123, and the water outlet end of the inner pipe 32122 is communicated with the warm water pipe 32152.

[0053] Specifically, when water is released from the water outlet of the reverse osmosis filter element and is sucked into the outer tube by the flow control pump, driven by the negative pressure, the room temperature pure water moves along the first water channel between the spiral outer tube and the inner tube toward the water inlet end of the heater. Driven by the negative pressure and assisted by the heater, the boiling water formed will directly enter the three-way connector from the water outlet of the heater. At this time, the boiling water will form two branches. A part of the boiling water will directly enter the hot water pipe from the three-way connector and flow into the mixing valve. When the user needs boiling water, the boiling water will directly enter the water inlet end of the heater. The two-outlet solenoid valve releases to the warm water outlet. At the same time, another part of the boiling water will enter the inner tube from the three-way connector. At this time, the flow direction of the boiling water is opposite to that of the normal temperature pure water. During the flow, the boiling water will take away the heat through the flow of normal temperature pure water until the boiling water becomes warm boiled water. The boiled water moves through the inner tube to the warm water pipe and enters the mixing valve under the push of negative pressure. When the user needs to drink warm boiled water, the boiled water is directly released from the one-inlet and two-outlet solenoid valve to the warm water outlet.

[0054] Furthermore, when the user needs to drink warm water of a certain temperature, the boiling water in the hot water pipe flows into the mixing valve, and the heated boiled water in the warm water pipe flows into the mixing valve. The ratio of boiling water to boiled water is adjusted by the mixing valve to obtain warm water of the temperature required by the user.

[0055] like Figures 4 to 9In the embedded water purifier shown, the mixing valve 3215 further includes a return pipe 32153 , the water inlet end of the return pipe 32153 is connected to the hot water pipe 32151 and the other end is connected to the water inlet end of the flow control pump 3214 . Optionally, in some embodiments, the reflux pipe can allow the boiling water filled in the mixing valve to flow back to the water inlet end of the flow control pump, and the heated boiling water can be mixed with the pure water at room temperature for circulation and heating again. Since the water in the first water channel is boiling water plus room temperature water at the beginning, it continuously absorbs the temperature of the boiling water moving toward the warm water pipe in the process of continuously moving toward the three-way connector. Therefore, the temperature of the water in the first water channel close to the three-way connector will be significantly hotter than the water just entering the first water channel, and the water from the water outlet end of the heater will be significantly higher than the water close to the warm water pipe. Through the reverse movement of room temperature water and boiling water and the heat exchange between the first water channel and the inner pipe, the heat loss can be better reduced, so that the water that needs to be heated can be preheated during the movement, and the water that needs to be cooled can dissipate heat during the movement, thereby ensuring the accuracy of the heat transfer direction in the process of forming a cycle.

[0056] Furthermore, a three-way component 3210 is provided on the cold boiled water module 321, the water inlet end of the three-way component 3210 is connected to the water outlet end of the flow control pump, and the other two ends of the three-way component are respectively connected to the outer pipe and the warm water pipe. Since the inner pipe is connected to the warm water pipe, the normal temperature water or the mixture of boiling water and normal temperature in the three-way component enters the outer pipe and starts to move along the first water channel between the inner pipe and the outer pipe, and the normal temperature water will not enter the warm water pipe. In this way, it is ensured that the water in the mixing valve is heated by the heating element, and the water that has not been heated by the heating element will not be mixed with the water that has been heated by the heating element, thereby ensuring the hygiene and safety of drinking water.

[0057] like Figures 4 to 9 In the embedded water purifier shown, the boiled water module 321 further includes a supporting shell 3217, the outer tube 32121 is arranged from top to bottom along the direction of the water flow of the inner tube 32122, the water inlet end of the inner tube 32122 is located at the lower side of the three-way connector 32123, an anti-backflow pipe 32125 is arranged between the water outlet end of the first water channel 32124 and the heating element 3211, and a guide 3218 is arranged on the supporting shell 3217, and a guide groove 3219 is arranged on the guide 3218 to support the outer tube 32121 to spiral. Furthermore, a check valve is arranged between the outer tube and the three-way connecting pipe to prevent the water of the first water channel or the water of the inner tube from directly moving from the outer tube to the three-way connecting pipe and entering the mixing valve.

[0058] Optionally, in some embodiments, the heating element is arranged from top to bottom, the water inlet end of the heating element is located at the lower side of the heating element, the water outlet end of the heating element is located at the upper side of the heating element, the outer tube is coiled on the outside of the heating element from top to bottom, and the inner tube is arranged inside the outer tube from top to bottom. When the normal temperature water moves toward the three-way connector, the normal temperature water moves from bottom to top along the outer tube, and the backflow prevention pipe is U-shaped and connected to the bottom of the heating element from top to bottom.

[0059] Furthermore, the height of the connection end between the three-way component and the outer pipe is higher than the height between the three-way component and the warm water pipe, so that the cold boiled water can move from top to bottom, while the normal temperature water moves upward under the push of the flow control pump.

[0060] Furthermore, the support shell can be used to install the heating element and support various pipelines. At the same time, the guide member can better fix the outer tube to prevent the outer tube from loosening. The guide groove is arranged along the winding direction of the outer tube, which can further limit the movement of the outer tube. Furthermore, the guide member is provided with two groups, one group is used to fix the upper side of the outer tube, and the other group is used to fix the lower side of the outer tube. The two groups of guide members are arranged relative to each other, which can save space and limit the deviation of the outer tube.

[0061] like Fig.10 An embedded water purifier is shown, wherein the reverse osmosis filter element 32 is provided with a waterway plate assembly 9, the waterway plate assembly 9 includes a waterway plate water inlet end 91 connected to the water outlet end of the composite filter element 31, a waterway plate water inlet solenoid valve connection end 92 connected to the reverse osmosis filter element water inlet end 110, a waterway plate pure water end 93 connected to the reverse osmosis filter element pure water end 120, a waterway plate waste water end 94 connected to the reverse osmosis filter element waste water end 130, a waterway plate waste water solenoid valve connection end 95 respectively connected to the waterway plate waste water end 94 and the reverse osmosis filter element waste water end 130, and a waterway plate boosting end 96 connected to the boosting assembly 33, and the waterway plate pure water end 93 is connected to a U-shaped one-way valve 931. Furthermore, as a preferred embodiment of the present invention but not a limitation, by optimizing the piping layout, adopting precise control components and reasonably setting the positions of various components, the piping layout of the waterway plate assembly is simple and compact, with high space utilization, which is easier to install and maintain, and can further improve the performance of the water purifier and user experience.

[0062] Furthermore, as a preferred embodiment of the present invention but not a limitation, the waterway board assembly assumes the function of water supply and diversion. The waterway board assembly includes key interfaces such as the waterway board water inlet end, the waterway board water inlet solenoid valve connection end, the waterway board boost end, the waterway board pure water end, the waterway board waste water solenoid valve connection end, and the waterway board waste water end, which are used to connect different components and divert the treated water.

[0063] The waterway assembly is also connected to the water inlet solenoid valve, booster pump, reverse osmosis filter element, wastewater solenoid valve and other equipment components, which can ensure the close connection between the various components and the smooth transfer of fluids. By optimizing the layout and structure of the waterway assembly, the pipeline can be simplified, the space utilization rate can be improved, and the user can use and maintain it more conveniently.

[0064] By setting the boosting end of the water circuit board between the water inlet end of the reverse osmosis filter element and the connection end of the water inlet solenoid valve, it can be ensured that the boosting pump can provide sufficient pressure to allow tap water to smoothly enter the reverse osmosis filter element for filtration. At the same time, due to the proper location of the boosting end of the water circuit board, unnecessary interference or influence on other components can be avoided. The water inlet solenoid valve, wastewater solenoid valve and other components used can achieve precise control of water flow and effective discharge of wastewater. This design improves the performance of the water purifier and user experience. The one-way valve connected to the pure water end of the water circuit board can ensure that the pure water treated by the filter element will not flow back, thereby ensuring the cleanliness and safety of the outlet water.

[0065] like Figures 1 to 15 In the embedded water purifier shown, the composite filter element 31 and the reverse osmosis filter element 32 are arranged in the vertical direction, the boiled water module 321 is arranged in the vertical direction and is located between the composite filter element 31 and the reverse osmosis filter element 32, the waterway plate assembly 9 is arranged in the horizontal direction and is located between the composite filter element 31 and the reverse osmosis filter element 32, and the boiled water module 321 is arranged on the lower side of the waterway plate assembly 9. Further, as a preferred embodiment of the present invention but not limited thereto, this layout helps to optimize the space utilization between the components of the water purifier, and is convenient for pipe connection and operation and maintenance. By vertically arranging the composite filter element, the reverse osmosis filter element, and the boiled water module and horizontally arranging the waterway plate assembly, the overall volume can be effectively reduced, and it is also conducive to the coordination and arrangement between the components. In addition, the boiled water module is arranged in the vertical direction and is located between the composite filter element and the reverse osmosis filter element, and the boiled water module is arranged on the lower side of the waterway plate assembly, which is conducive to the transfer and distribution of heat, thereby better realizing the functions of heating and cooling. This design can make the structure of the water purifier more compact and efficient. The arrangement of the boiled water module and the water board assembly allows them to maintain a certain distance in space to avoid mutual interference.

[0066] like Figures 13 to 15In the embedded water purifier shown, a wastewater receiving box 53 is provided at the lower side of the drinking water outlet 5, a two-way check pump 10 is connected between the wastewater receiving box 53 and the wastewater end 94 of the waterway plate, and the wastewater receiving box 53 is provided with a wastewater level monitoring component 531, which is used to drive the two-way check pump 10 to start, so that the wastewater in the wastewater receiving box 53 is discharged to the wastewater outlet 8. Further, as a preferred embodiment of the present invention but not a limitation, this design can effectively collect and discharge wastewater. The setting of the two-way check pump can prevent the wastewater from flowing back into the water purifier, so the user does not need to manually clean the wastewater receiving box, and it can also prevent the wastewater from being retained in the water purifier or the wastewater receiving box for a long time, thereby ensuring the cleanliness and sanitation of the water purifier. The wastewater level monitoring component can monitor the wastewater level in the wastewater receiving box in real time. When the water level reaches a certain height, the monitoring component will start the two-way check pump to discharge the wastewater. This design is not only conducive to protecting the sanitation and safety of drinking water or domestic water in the water purifier, but also can effectively save water resources and reduce the discharge of wastewater. Optionally, in some embodiments, the water at the wastewater end of the waterway plate flows from the two-way check pump to the wastewater receiving box, the height of the two-way check pump is higher than the height of the wastewater receiving box, and the bottom of the two-way check pump and the bottom of the wastewater receiving box are connected with a U-shaped pipe, which can prevent water from flowing back from the wastewater receiving box to the wastewater end of the waterway plate.

[0067] like Figures 1 to 15 An embedded water purifier is shown, the boiled water module 321 also includes a zero-pressure valve 3213 connected to the downstream end of the water outlet of the reverse osmosis filter element 32, a flow control pump 3214 located at the downstream end of the zero-pressure valve 3213, a mixing valve 3215 connected to the upstream end of the warm and hot water outlet 52, and a one-inlet and two-outlet solenoid valve 3216 connected to the downstream end of the mixing valve 3215, and the water outlet ends of the one-inlet and two-outlet solenoid valve 3216 are respectively connected to the waste water receiving box 53 and the warm and hot water outlet 52.

[0068] The boiled water module is used to heat and cool pure water to a certain temperature. The flow control pump can be used to control the flow of warm water. The mixing valve can be used to mix warm water with normal temperature pure water. The temperature and flow of warm water can be accurately controlled by the flow control pump and the mixing valve to provide the temperature and water volume required by the user. The present invention has the advantages of high intelligence and simple operation, and can meet the needs of different users.

[0069] Furthermore, as a preferred embodiment of the present invention but not a limitation, the zero-pressure valve can effectively prevent the water system pressure from being too high or too low, and ensure the normal operation of the water system. Specifically, when the flow control pump extracts pure water from the pure water end and sends it to the boiled water module for heating treatment, if the water system pressure is too high or too low, it will affect the normal operation of the equipment.

[0070] When the pressure in the warm water pipe is too high, the zero pressure valve will automatically close to keep the pressure of the water pipe stable, thereby improving the service life and stability of the equipment. In some embodiments, when the water pressure drops below a certain threshold, the zero pressure valve will close to prevent backflow under negative pressure.

[0071] Furthermore, as a preferred embodiment of the present invention but not a limitation, a one-inlet and two-outlet solenoid valve is between the mixing valve and the warm and hot water outlet, which can control the flow of warm and hot water. The mixing valve can control the water inlet flow of the one-inlet and two-outlet solenoid valve, so that a part of the warm and hot water enters the warm and hot water outlet from the mixing valve to be supplied to the user. If the user does not need warm water or needs warm water of a different temperature, the other part of the unused warm and hot water will flow to the wastewater receiving box, which can avoid wasting resources and wastewater discharge. This structure can make the boiled water system more flexible and efficient. By controlling the degree of opening of the mixing valve and the one-inlet and two-outlet solenoid valve, the requirements of different temperatures and flows can be met, providing users with a more convenient and comfortable drinking experience.

[0072] Further, as a preferred embodiment of the present invention but not limited thereto, the wastewater and sewage discharge functions of the water system of the water purifier simultaneously realize the function of a two-way check pump to prevent wastewater from flowing back into the water system. The water receiving box can collect wastewater, and the two-way check pump can be used to pump wastewater out of the water receiving box and discharge it into a sewer or sewage treatment system.

[0073] like Figures 1 to 15 In the embedded water purifier shown, the water inlet direction of the waterway plate water inlet end 91 is parallel to the water outlet direction of the waterway plate wastewater end 94, the water outlet direction of the waterway plate pure water end 93 is perpendicular to the water inlet direction of the waterway plate water inlet end 91, the waterway plate water inlet solenoid valve connection end 92 is located on the left side of the waterway plate assembly 9, the waterway plate wastewater solenoid valve connection end 95 is located on the right side of the waterway plate assembly 9, and the booster assembly 33 is connected to the lower side of the waterway plate assembly 9. Further, as a preferred embodiment of the present invention but not limited to, the waterway plate booster water inlet end and the waterway plate booster water outlet end are arranged in the vertical direction, so that the booster pump can be more easily installed and fixed in a suitable position of the water purifier. At the same time, the booster pump is located on the lower side of the waterway plate body, which can effectively save the space of the water purifier and improve the space compactness of the water purifier, which can facilitate users to carry out daily maintenance and overhaul, and also make the booster pump more stable and reliable when working.

[0074] The water inlet direction of the waterway plate water inlet end 91 is parallel to the water outlet direction of the waterway plate wastewater end 94, and the water outlet direction of the waterway plate pure water end 93 is perpendicular to the water inlet direction of the waterway plate water inlet end 91. In addition, the water outlet of the waterway plate pure water end 93 is located between the water inlet end of the waterway plate water inlet end 91 and the water outlet end of the waterway plate wastewater end 94. Further, as a preferred embodiment of the present invention but not a limitation, this design can effectively distinguish the flow direction of the incoming water, wastewater and pure water, thereby ensuring that the water is correctly diverted and treated during the purification process. At the same time, the vertical pure water outlet direction helps to avoid the mixing of pure water and untreated water, thereby ensuring the quality of the purified water.

[0075] Further, as a preferred embodiment of the present invention but not limitation, since the waterway plate water inlet solenoid valve connection end and the waterway plate wastewater solenoid valve connection end are respectively located on different sides of the waterway plate body, the water inlet solenoid valve and the wastewater solenoid valve of the water purifier can be arranged together more compactly, thereby saving space for the water purifier. This makes it easier to install the water inlet solenoid valve and the wastewater solenoid valve on the waterway plate, which is convenient for users to maintain. This setting provides a clear separation for the flow direction of water inlet and wastewater, and no matter which layout method is used, it is conducive to the layout of the pipeline and the control of the water flow. This design also helps to reduce pipeline crossing and confusion, thereby improving the overall maintainability and operability of the system. At the same time, it also makes the flow of water inlet and wastewater smoother.

[0076] like Figures 11 to 13An embedded water purifier is shown, the warm and hot water outlet end 52 is provided with a warm and hot water outlet shell 521, the warm and hot water outlet shell 521 is provided with a warm and hot water inlet 522 connected to the one-inlet and two-outlet solenoid valve 3216, a warm and hot water outlet 523 for releasing warm hot water, and a warm and hot water outlet shell inner cavity 524 located between the warm and hot water inlet 522 and the warm and hot water outlet 523, and a warm and hot water outlet shell opening 525 is also provided on the lower side of the warm and hot water outlet shell 521, the outer diameter of the warm and hot water outlet shell opening 525 is larger than the outer diameter of the warm and hot water outlet 523, and a separation channel 526 connected to the warm and hot water outlet shell inner cavity 524 and for steam to escape is provided between the warm and hot water outlet opening 525 and the warm and hot water outlet 523. Furthermore, the warm and hot water outlet and the opening of the warm and hot water outlet shell are both concentric circles, and the separation channel is arranged in a ring shape between the inner wall of the inner cavity of the warm and hot water outlet shell and the outer wall of the warm and hot water outlet. Optionally, in some embodiments, when the water temperature is high, the warm and hot water outlet speed is slow and there is more steam, and when the water temperature is low, the warm and hot water outlet speed is fast and there is less steam. The warm and hot water outlet end releases warm water from top to bottom, and the warm water passes through the mixing valve and enters the one-inlet and two-outlet solenoid valve, and then enters the warm and hot water inlet, and flows out of the warm and hot water outlet on the lower side from the inner cavity of the warm and hot water outlet shell, and the steam of the warm water escapes from the inner cavity of the warm and hot water outlet shell through the separation channel, thereby avoiding poor water outlet of the warm and hot water outlet, or the water contains a large amount of steam, which causes abnormal noise and intermittent water outlet from the warm and hot water outlet.

[0077] like Figures 11 to 13 In the embedded water purifier shown, a baffle 5241 extending from top to bottom is provided at the center of the inner cavity 524 of the warm and hot water outlet housing, the water inlet direction of the warm and hot water inlet 522 moves in the horizontal direction, the lower end surface of the baffle 5241 is equal to or lower than the lower end surface of the warm and hot water inlet 522, and the upper end surface of the separation channel 526 is equal to or higher than the upper end surface of the warm and hot water inlet 522. The separation channel is located on the side of the baffle. In some embodiments, the baffle can block the warm water of the warm and hot water inlet, the warm water moves downward, and the steam escapes outward from the separation channel on the side. When the upper end surface of the separation channel is higher than the warm and hot water inlet, when the water temperature is high, the warm and hot water outlet speed is slow, the steam is more, and the steam moves upward to the upper end surface of the separation channel. When the water temperature is low, the warm and hot water outlet speed is fast, the steam is less, a large amount of water fills the inner cavity of the warm and hot water outlet housing, and part of the hot water that cannot be discharged from the warm and hot water outlet will be discharged outward from the separation channel.

By optimizing the layout and structure of the waterway plate assembly 9, the pipeline can be simplified, the space utilization rate can be improved, and the user can use and maintain it more conveniently.

[0086] A wastewater receiving box 53 is provided at the lower side of the drinking water outlet 5, and a two-way check water pump 10 is connected between the wastewater receiving box 53 and the wastewater end 94 of the waterway plate.

[0090] like Figures 1 to 15 As shown, the implementation method of Example 2 is as follows:

[0091] Embodiment 2 is based on Embodiment 1 and further has the following implementation modes:

[0092] The mixing valve 3215 is provided with a hot water pipe 32151 and a warm water pipe 32152. The cooling component 3212 includes a spirally arranged outer pipe 32121, an inner pipe 32122 located inside the outer pipe 32121, and a three-way connector 32123 respectively connected to the water outlet end of the heating element 3211, the inner pipe 32122, and the hot water pipe 32151. A first water channel 32124 is provided between the outer pipe 32121 and the inner pipe 32122. The water inlet end of the first water channel 32124 is connected to the water outlet end of the flow control pump 3214, and the water outlet end of the first water channel 32124 is connected to the water inlet end of the heating element 3211. The water inlet end of the inner pipe 32122 is connected to the three-way connector 32123, and the water outlet end of the inner pipe 32122 is connected to the warm water pipe 32152.

[0093] Specifically, when water is released from the water outlet end of the reverse osmosis filter element 32 and is sucked into the outer tube 32121 by the flow control pump 3214, driven by the negative pressure, the room temperature pure water moves along the first water channel 32124 between the spiral outer tube 32121 and the inner tube 32122 toward the water inlet end of the heating element 3211. Driven by the negative pressure and assisted by the heating element 3211, the boiling water formed will directly enter the three-way connector 32123 from the water outlet end of the heating element 3211. At this time, the boiling water will form two branches. A part of the boiling water will directly enter the hot water pipe 32151 from the three-way connector 32123 and flow into the mixing valve 3215. When the user needs When boiling water, the boiling water is directly released from the one-inlet and two-outlet solenoid valve 3216 to the warm water outlet 52. At the same time, another part of the boiling water will enter the inner tube 32122 from the three-way connector 32123. At this time, the flow direction of the boiling water is opposite to the flow direction of the normal temperature pure water. During the flow process, the boiling water will take away the heat through the flow of the normal temperature pure water until the boiling water becomes warm boiled water. The boiled water moves to the warm water pipe 32152 through the inner tube 32122 and enters the mixing valve 3215 under the push of negative pressure. When the user needs to drink warm boiled water, the boiled water is directly released from the one-inlet and two-outlet solenoid valve 3216 to the warm water outlet 52.

[0094] Furthermore, when the user needs to drink warm water of a certain temperature, the boiling water in the hot water pipe 32151 flows into the mixing valve 3215, and the heated boiled water in the warm water pipe 32152 flows into the mixing valve 3215. The ratio of boiling water and boiled water is adjusted by the mixing valve 3215 to obtain warm water of the temperature required by the user.

[0095] The mixing valve 3215 also includes a return pipe 32153, the water inlet end of the return pipe 32153 is connected to the hot water pipe 32151 and the other end is connected to the water inlet end of the flow control pump 3214. The return pipe 32153 can make the boiling water filled in the mixing valve 3215 return to the water inlet end of the flow control pump 3214, and the boiling water with temperature can be mixed with the pure water at room temperature for circulation and heating again. Since the water in the first water channel 32124 is boiling water and room temperature water at the beginning, it continuously absorbs the temperature of the boiling water moving toward the warm water pipe 32152 during the process of continuously moving toward the three-way connector 32123. Therefore, when the temperature of the water in the first water channel 32124 close to the three-way connector 32123 is higher than that of the water in the first water channel 32124, the water in the first water channel 32124 is higher than that of the water in the first water channel 32124. The temperature of the water will be significantly higher than the water just entering the first water channel 32124, and the water from the water outlet of the heating element 3211 will be significantly higher than the water near the warm water pipe 32152. Through the reverse movement of normal temperature water and boiling water and the heat exchange between the first water channel 32124 and the inner tube 32122, the heat loss can be better reduced, so that the water that needs to be heated can be preheated during the movement, and the water that needs to be cooled can dissipate the heat during the movement, thereby ensuring the accuracy of the heat transfer direction in the circulation process.

[0096] Furthermore, a three-way component 3210 is provided on the cold boiled water module 321, the water inlet end of the three-way component 3210 is connected to the water outlet end of the flow control pump 3214, and the other two ends of the three-way component 3210 are respectively connected to the outer pipe 32121 and the warm water pipe 32152. Since the inner pipe 32122 is connected to the warm water pipe 32152, the normal temperature water or the mixed liquid of boiling water and normal temperature in the three-way component 3210 enters the outer pipe 32121 and starts to move along the first water channel 32124 between the inner pipe 32122 and the outer pipe 32121, and the normal temperature water will not enter the warm water pipe 32152. In this way, it is ensured that the water in the mixing valve 3215 is heated by the heating element 3211, and the water that has not been treated by the heating element 3211 will not be mixed with the water that has been treated by the heating element 3211, thereby ensuring the hygiene and safety of drinking water.

[0097] The boiled water module 321 further includes a supporting shell 3217, the outer tube 32121 is arranged from top to bottom along the direction of the water flow of the inner tube 32122, the water inlet end of the inner tube 32122 is located at the lower side of the three-way connector 32123, a backflow prevention pipe 32125 is arranged between the water outlet end of the first water channel 32124 and the heating element 3211, and a guide member 3218 is arranged on the supporting shell 3217, and a guide groove 3219 is arranged on the guide member 3218 to support the outer tube 32121 to spiral. Further, a check valve 32120 is arranged between the outer tube 32121 and the three-way connector 32123 to prevent the water of the first water channel 32124 or the water of the inner tube 32122 from directly moving from the outer tube 32121 to the three-way connector 32123 and entering the water mixing valve 3215.

[0098] The heating element 3211 is arranged from top to bottom, the water inlet end of the heating element 3211 is located at the lower side of the heating element 3211, the water outlet end of the heating element 3211 is located at the upper side of the heating element 3211, the outer tube 32121 is coiled on the outside of the heating element 3211 from top to bottom, and the inner tube 32122 is arranged inside the outer tube 32121 from top to bottom. When the normal temperature water moves toward the three-way connector 32123, the normal temperature water moves from bottom to top along the outer tube 32121, and the backflow prevention pipe 32125 is U-shaped and connected to the bottom of the heating element 3211 from top to bottom.

[0099] Furthermore, the height of the connection end between the three-way component 3210 and the outer tube 32121 is higher than the height between the three-way component 3210 and the warm water pipe 32152, so that the cold boiled water can move from top to bottom. The normal temperature water moves upward under the push of the flow control pump 3214.

[0100] Furthermore, the support shell 3217 can be used to install the heating element 3211 and support various pipelines. At the same time, the guide member 3218 can better fix the outer tube 32121 to prevent the outer tube 32121 from loosening. The guide groove 3219 is arranged along the winding direction of the outer tube 32121, which can further limit the movement of the outer tube 32121. Furthermore, the guide member 3218 is provided with two groups, one group is used to fix the upper side of the outer tube 32121, and the other group is used to fix the lower side of the outer tube 32121. The two groups of guide members 3218 are arranged relative to each other, which can save space and limit the deviation of the outer tube 32121.

[0101] The warm and hot water outlet end 52 is provided with a warm and hot water outlet shell 521, on which a warm and hot water inlet 522 connected to the one-inlet-two-outlet solenoid valve 3216, a warm and hot water outlet 523 for releasing warm hot water, and a warm and hot water outlet shell inner cavity 524 located between the warm and hot water inlet 522 and the warm and hot water outlet 523 are provided. A warm and hot water outlet shell opening 525 is also provided on the lower side of the warm and hot water outlet shell 521. The outer diameter of the warm and hot water outlet shell opening 525 is larger than the outer diameter of the warm and hot water outlet 523. A separation channel 526 that is connected to the warm and hot water outlet shell inner cavity 524 and allows steam to escape is provided between the warm and hot water outlet opening 525 and the warm and hot water outlet 523. Furthermore, the warm water outlet 523 and the warm water outlet shell opening 525 are both concentric circles, and the separation channel 526 is arranged in a ring shape between the inner wall of the warm water outlet shell cavity 524 and the outer wall of the warm water outlet 523. When the water temperature is high, the warm water outlet speed is slow and there is more steam. When the water temperature is low, the warm water outlet speed is fast and there is less steam. The warm water outlet end 52 releases warm water from top to bottom. The warm water passes through the mixing valve 3215 and enters the one-inlet and two-outlet solenoid valve 3216, and then enters the warm water inlet 522, and flows out of the warm water from the warm water outlet shell cavity 524 to the warm water outlet 523 on the lower side. The steam of the warm water escapes from the warm water outlet shell cavity 524 through the separation channel 526, thereby avoiding the situation where the warm water outlet 523 does not have smooth water outlet, or the water contains a large amount of steam from the warm water outlet 523, causing abnormal noise and intermittent water outlet process.

[0102] A baffle 5241 extending from top to bottom is provided at the center of the inner cavity 524 of the warm and hot water outlet shell, and the water inlet direction of the warm and hot water inlet 522 moves in the horizontal direction. The lower end surface of the baffle 5241 is equal to or lower than the lower end surface of the warm and hot water inlet 522, and the upper end surface of the separation channel 526 is equal to or higher than the upper end surface of the water inlet 522. The separation channel 526 is located on the side of the baffle 5241, and the baffle 5241 can block the warm water in the warm and hot water inlet 522. The warm water moves downward, and the steam escapes outward from the side separation channel 526. When the upper end surface of the separation channel 526 is higher than the warm and hot water inlet 522, when the water temperature is high, the warm and hot water outflow speed is slow, and there is more steam. The steam moves upward to the upper end surface of the separation channel 526. When the water temperature is low, the warm and hot water outflow speed is fast, and there is less steam. A large amount of water fills the inner cavity 524 of the warm and hot water outlet shell, and some of the hot water that cannot be discharged from the warm and hot water outlet 523 will be discharged outward from the separation channel 526, further increasing the water outflow speed.
