Description

Technical Field

[0001] This utility model relates to a water system and water purifier with adjustable mineral content. Background Technology

[0002] As people's living standards improve, they are paying more and more attention to health. Minerals, like vitamins, are essential elements for the human body. Since minerals cannot be synthesized by the body itself, they must be obtained from external sources. With increasing concern about drinking water safety, water purification equipment such as reverse osmosis, nanofiltration, and ultrafiltration water purifiers are becoming increasingly popular. These types of water purifiers have high filtration precision and can effectively remove harmful substances from drinking water, but they also remove trace minerals from the water source. Therefore, there is a need for a water purifier with adjustable mineral content. Although existing water purifiers add minerals to the post-filter or subsequent water path to adjust the mineral content at the outlet, this method has a relatively small range for adjusting mineral content, making it difficult to meet the mineral needs of people of different ages. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defect that the range of mineral content adjustment in existing water purifiers is relatively small, and to provide a water system and water purifier with adjustable mineral content.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] A water system with adjustable mineral content, comprising:

[0006] The ambient temperature water circuit has one end for connecting to the tap water end and the other end for connecting to the ambient temperature water end. A pre-filter and a post-filter are installed sequentially along the water flow direction on the ambient temperature water circuit.

[0007] The mineral water circuit has one end connected to the pipeline between the pre-filter and the post-filter, and the other end connected to the ambient temperature water circuit and located close to the ambient temperature water end. A water storage tank and a flow regulation unit are installed on the mineral water circuit along the water flow direction.

[0008] In this design, the pre-filter comprises a pre-filter section and a post-filter section. At room temperature, water flows sequentially through the pre-filter section, the post-filter section, and the post-filter section. The pre-filter consists of PP cotton, pre-activated carbon, post-activated carbon, and an ultrafiltration filter. The pre-filter section removes large particles such as sediment and rust, as well as residual chlorine. The post-filter section adsorbs odors, improves taste, and traps bacteria. The post-filter consists of a nanofiltration filter and a membrane chromatography filter, used to remove heavy metals, microorganisms, bacteria, and other harmful substances, selectively removing heavy metals while retaining minerals.

[0009] This water system filters tap water from the mains through a pre-filter. A portion of this water then passes through a mineral water path and is stored in a tank. This portion of water is not filtered by a post-filter, resulting in water rich in minerals. The remaining water passes through both the pre-filter and post-filter in the ambient temperature water path, resulting in purified water with very low mineral content. Users can adjust the mineral content of the ambient temperature water by regulating the flow rate in the mineral water path and mixing it with the purified water in the ambient temperature water path to obtain purified water with varying mineral content, thus meeting diverse user needs.

[0010] Preferably, the flow regulation unit includes a first drive pump, a first check valve, a controller, a first TDS (Total Dissolved Solids) sensor, and a second TDS sensor. The first drive pump, the first check valve, and the first TDS sensor are all installed in the mineral water circuit and located downstream of the water storage tank. The first drive pump is located upstream of the first check valve. The second TDS sensor is installed in the ambient temperature water circuit and close to the ambient temperature water end. The first drive pump, the first TDS sensor, and the second TDS sensor are all electrically connected to the controller.

[0011] In this solution, the TDS sensor is used to detect mineral content. A first check valve prevents backflow of water from the ambient temperature water path into the storage tank. A first TDS sensor detects the mineral content of the water in the mineral water path, and a second TDS sensor detects the mineral content of the water in the ambient temperature water path. The controller, based on the data from the first and second TDS sensors, controls the flow rate of the first drive pump, ensuring that the ambient temperature water path provides the user with the desired concentration of mineral water.

[0012] Of course, in other solutions, the flow regulation unit can also use a flow regulation valve to regulate the flow rate of mineral water.

[0013] Preferably, a first solenoid valve is installed on the mineral water line, and the first solenoid valve is located upstream of the water storage tank.

[0014] In this design, the first solenoid valve is used to open or close the mineral water circuit. When the first solenoid valve is opened, tap water from the tap water supply is filtered through the pre-filter and then stored in the water tank through the mineral water circuit. This water is not filtered by the post-filter, resulting in water in the water tank being rich in minerals. When the water tank is full or reaches the set level, the first solenoid valve can be closed.

[0015] Preferably, the water system further includes a level gauge and a controller. The level gauge is installed in the inner cavity of the water storage tank, and the level gauge is electrically connected to the controller. The controller is electrically connected to the first solenoid valve.

[0016] In this solution, the level gauge is used to detect the liquid level in the water storage tank. When the water in the storage tank is full or reaches the set liquid level value, the level gauge sends a signal to the controller. The controller closes the first solenoid valve according to the signal from the level gauge, cutting off the water supply to the storage tank.

[0017] Preferably, a second solenoid valve is also installed on the ambient temperature water line and is located near the ambient temperature water end.

[0018] In this design, the second solenoid valve is used to open or close the ambient temperature water circuit. When the second solenoid valve is open, the user receives the required purified water at the ambient temperature end. When the user does not need purified water, the second solenoid valve can be closed.

[0019] Preferably, the water system further includes a hot water circuit, one end of which is connected to and close to the ambient temperature water circuit, and the connection point between the hot water circuit and the ambient temperature water circuit is located upstream of the second solenoid valve. The other end of the hot water circuit is used to connect to the hot water circuit. A negative pressure valve, a second drive pump, and a heating element are installed on the hot water circuit along the water flow direction.

[0020] In this solution, the hot water circuit is used to obtain the required hot water. A second drive pump, in conjunction with a negative pressure valve, replaces the traditional heating and storage tank for hot water, achieving instant filtration, instant heating, and instant drinking water functionality while saving energy. When the second drive pump is working, the negative pressure valve opens, allowing purified water from the ambient temperature circuit to flow through the hot water circuit to the heating element for heating, obtaining the user's required hot water at the hot water end—heating only the amount of hot water needed.

[0021] When using hot water, the flow rate is relatively small (normal temperature water has a larger flow rate, reaching over 2L / min, while hot water flow rate is smaller, ranging from 0.4 to 1L / min, otherwise the pressure before the filter membrane would increase). In this case, some water can be recycled and stored in the water tank. This reduces water waste and allows for the reserve of adjustable mineral water. At the same time, the opening of the mineral water circuit reduces the pressure before the filter membrane, protecting the filter and extending its service life.

[0022] Preferably, a first temperature sensor and a second temperature sensor are respectively installed at both ends of the heating element, and the first temperature sensor, the second temperature sensor, the heating element and the second drive pump are all electrically connected to the controller.

[0023] In this solution, the first temperature sensor and the second temperature sensor are used to detect the inlet water temperature and the outlet water temperature of the heating element, respectively. The controller adjusts the power of the heating element according to the inlet water temperature and the outlet water temperature, so that the user can obtain hot water at the required temperature at the water outlet.

[0024] Preferably, the wastewater outlet of the post-filter is connected to a wastewater pipeline, and an adjustable wastewater flow valve is installed on the wastewater pipeline.

[0025] In this design, the wastewater flow rate adjustable valve is used to regulate the wastewater flow rate through the wastewater inlet. During water production, the opening of the wastewater flow rate adjustable valve can be reduced to decrease the flow rate at the wastewater inlet, maintaining a certain pre-membrane pressure for the post-filter cartridge and increasing the flow rate of the purified water produced. During rinsing, the opening of the wastewater flow rate adjustable valve is increased to increase the flow rate at the wastewater inlet, rinsing the post-filter cartridge.

[0026] Preferably, the bottom of the water storage tank is provided with a drain outlet, and the drain outlet is equipped with a drain valve;

[0027] Alternatively, the bottom of the water storage tank is connected to a drain pipe, and the end of the drain pipe away from the water storage tank is connected to the wastewater pipe. A third drive pump and a second check valve are installed on the drain pipe, with the second check valve located downstream of the third drive pump.

[0028] In this solution, when the water system is not used for a long time, the water in the storage tank can be drained by opening the drain valve, and mineral water can be stored again to improve the cleanliness.

[0029] Preferably, the inner cavity of the water storage tank is equipped with a germicidal lamp for sterilizing the mineral water.

[0030] Preferably, a fourth drive pump is also installed on the pipeline between the pre-filter and the post-filter.

[0031] In this scheme, the fourth drive pump is used to pressurize the water circuit so as to maintain a certain pre-membrane pressure for the post-filter cartridge, which facilitates the production of a large flow of purified water.

[0032] A water purifier comprising a water circuit system with adjustable mineral content as described above.

[0033] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.

[0034] The positive and progressive effects of this utility model are as follows: After the tap water at the tap water end is filtered by the pre-filter, a portion of the water is stored in the storage tank through the mineral water path. This portion of water is not filtered by the post-filter, making the water stored in the storage tank rich in minerals. The other portion of water passes through the pre-filter and post-filter of the room temperature water path to obtain purified water at the room temperature water end, which has a very low mineral content. When the user needs to adjust the mineral content of the water at the room temperature water end, the flow rate of the mineral water path can be adjusted by the flow regulating unit, and the purified water on the room temperature water path can be mixed with the purified water at the room temperature water end to obtain purified water with different mineral contents to meet the diverse needs of users.

[0067] The present invention will be described more clearly and completely below by way of embodiments and in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments described herein.

[0068] like Figure 1 As shown, this embodiment discloses a water system with adjustable mineral content. The water system includes a room temperature water channel 10 and a mineral water channel 20. One end of the room temperature water channel 10 is connected to a tap water terminal 30, and the other end is connected to a room temperature water terminal 40. A pre-filter 101 and a post-filter 102 are installed sequentially on the room temperature water channel 10 along the water flow direction. One end of the mineral water channel 20 is connected to the pipeline between the pre-filter 101 and the post-filter 102, and the other end of the mineral water channel 20 is connected to the room temperature water channel 10 and is located close to the room temperature water terminal 40. A water storage tank 201 and a flow regulating unit 202 are installed on the mineral water channel 20 along the water flow direction.

[0069] like Figure 1 As shown, in this embodiment, the pre-filter 101 includes a pre-filter section and a post-filter section. Water in the ambient temperature water path 10 sequentially passes through the pre-filter section of the pre-filter 101, the post-filter 102, and the post-filter section of the pre-filter 101. The pre-filter 101 comprises PP cotton, pre-activated carbon, post-activated carbon filters, and an ultrafiltration filter. The pre-filter section of the pre-filter 101 removes large particles of impurities such as sediment and rust, as well as residual chlorine. The post-filter section of the pre-filter 101 adsorbs odors, improves taste, and intercepts bacteria. The post-filter 102 comprises a nanofiltration filter and a membrane chromatography filter, used to remove heavy metals, microorganisms, bacteria, and other harmful substances, selectively removing heavy metals while retaining minerals.

[0070] like Figure 1 As shown, this water system filters tap water from tap water terminal 30 through pre-filter 101. A portion of the water passes through mineral water channel 20 and is stored in water tank 201. This portion of water is not filtered by post-filter 102, resulting in water in water tank 201 rich in minerals. The other portion of water passes through pre-filter 101 and post-filter 102 on ambient temperature water channel 10 to obtain purified water at ambient temperature water terminal 40, which has very low mineral content. When users need to adjust the mineral content of the water at ambient temperature water terminal 40, they can adjust the flow rate on mineral water channel 20 through flow adjustment unit 202 and mix it with the purified water on ambient temperature water channel 10 at ambient temperature water terminal 40 to obtain purified water with different mineral contents to meet the diverse needs of users.

[0071] like Figure 1 As shown, the flow regulation unit 202 includes a first drive pump 2021, a first check valve 2022, a controller (not shown), a first TDS (Total Dissolved Solids) sensor 2023, and a second TDS sensor 2024. The first drive pump 2021, the first check valve 2022, and the first TDS sensor 2023 are all installed in the mineral water path 20 and located downstream of the storage tank 201. The first drive pump 2021 is located upstream of the first check valve 2022. The second TDS sensor 2024 is installed in the ambient temperature water path 10 and near the ambient temperature water end 40. The first drive pump 2021, the first TDS sensor 2023, and the second TDS sensor 2024 are all electrically connected to the controller. The TDS sensor is used to detect mineral content. The first check valve 2022 is used to prevent water from the ambient temperature water path 10 from flowing back into the storage tank 201. The first TDS sensor 2023 is used to detect the mineral content of the water in the mineral water channel 20, and the second TDS sensor 2024 is used to detect the mineral content of the water in the room temperature water terminal 40. The controller controls the flow rate of the first drive pump 2021 based on the detection data of the first TDS sensor 2023 and the second TDS sensor 2024, so that the mineral water with the concentration required by the user is obtained in the room temperature water terminal 40.

[0072] When the first drive pump 2021 is working, the first check valve 2022 is opened, and the water in the water storage tank 201 flows to the room temperature water end 40 through the mineral water passage 20. When the first drive pump 2021 is turned off, the first check valve 2022 closes the outlet of the water storage tank 201.

[0073] Of course, in other embodiments, the flow regulating unit may also employ a flow regulating valve to regulate the flow rate of mineral water.

[0074] like Figure 1As shown, a first solenoid valve 203 is installed on the mineral water circuit 20, located upstream of the water storage tank 201. The first solenoid valve 203 is used to open or close the mineral water circuit 20. When the first solenoid valve 203 is opened, the tap water from the tap water terminal 30 is filtered through the pre-filter 101 and then stored in the water storage tank 201 through the mineral water circuit 20. This water is not filtered by the post-filter 102, making the water stored in the water storage tank 201 rich in minerals. When the water in the water storage tank 201 is full or reaches the set liquid level, the first solenoid valve 203 can be closed.

[0075] like Figure 1 As shown, the water system also includes a level gauge 2012 and a controller. The level gauge 2012 is installed inside the water storage tank 201 and is electrically connected to the controller, which is in turn electrically connected to the first solenoid valve 203. The level gauge 2012 is used to detect the water level in the water storage tank 201. When the water in the water storage tank 201 is full or reaches a set level, the level gauge 2012 sends a signal to the controller. Based on the signal from the level gauge 2012, the controller closes the first solenoid valve 203, cutting off the water supply to the water storage tank 201.

[0076] like Figure 1 As shown, a second solenoid valve 103 is also installed on the ambient temperature water circuit 10 and is located near the ambient temperature water end 40. The second solenoid valve 103 is used to open or close the ambient temperature water circuit 10. When the second solenoid valve 103 is opened, the user obtains the required purified water at the ambient temperature water end 40. When the user does not need purified water, the second solenoid valve 103 can be closed.

[0077] like Figure 1 As shown, in this embodiment, a fourth drive pump 104 is also installed on the pipeline between the pre-filter 101 and the post-filter 102. The fourth drive pump 104 is used to pressurize the water circuit so as to maintain a certain pre-membrane pressure for the post-filter 102, which facilitates the production of a large flow of purified water.

[0078] like Figure 1As shown, the water system also includes a hot water circuit 50. One end of the hot water circuit 50 is connected to the ambient temperature water circuit 10 and is close to the ambient temperature water end 40. The connection point between the hot water circuit 50 and the ambient temperature water circuit 10 is located upstream of the second solenoid valve 103. The other end of the hot water circuit 50 is used to connect to the hot water end 60. A negative pressure valve 501, a second drive pump 502, and a heating element 503 are installed on the hot water circuit 50 along the water flow direction. The hot water circuit 50 is used to obtain the required hot water at the hot water end 60. Through the cooperation of the second drive pump 502 and the negative pressure valve 501, the traditional heating and storage tank for hot water is replaced, realizing the functions of instant filtration, instant heating, and instant drinking, saving energy. When the second drive pump 502 is working, the negative pressure valve 501 is opened, and the purified water from the ambient temperature water circuit 10 flows through the hot water circuit 50 to the heating element 503 for heating, obtaining the user's required hot water at the hot water end 60. The amount of hot water needed is heated.

[0079] When using hot water, the flow rate is relatively small (normal temperature water has a larger flow rate, reaching over 2L / min, while hot water flow rate is smaller, ranging from 0.4 to 1L / min, otherwise the pressure before the filter membrane would increase). In this case, some water can be recycled and stored in the water storage tank 201. This reduces water waste and allows for the reserve of adjustable mineral water. At the same time, the opening of the mineral water circuit 20 reduces the pressure before the filter membrane, protecting the filter and extending its service life.

[0080] like Figure 1 As shown, a first temperature sensor 504 and a second temperature sensor 505 are respectively installed at both ends of the heating element 503. The first temperature sensor 504, the second temperature sensor 505, the heating element 503, and the second drive pump 502 are all electrically connected to the controller. The first temperature sensor 504 and the second temperature sensor 505 are used to detect the inlet water temperature and the outlet water temperature of the heating element 503, respectively. The controller adjusts the power of the heating element 503 according to the inlet water temperature and the outlet water temperature, so that the user can obtain hot water at the hot water end 60 with the required water temperature.

[0081] like Figure 1 As shown, the wastewater inlet of the post-filter 102 is connected to a wastewater pipeline 70, and a wastewater flow rate adjustable valve 701 is installed on the wastewater pipeline 70. The wastewater flow rate adjustable valve 701 is used to regulate the wastewater flow rate through the wastewater inlet. During water production, the opening of the wastewater flow rate adjustable valve 701 can be reduced to decrease the flow rate at the wastewater inlet, thereby maintaining a certain pre-membrane pressure in the post-filter 102 and increasing the flow rate of the purified water produced. During rinsing, the opening of the wastewater flow rate adjustable valve 701 is increased to increase the flow rate at the wastewater inlet, thus rinsing the post-filter 102.

[0082] In this embodiment, a wastewater solenoid valve 702 for switching on and off is installed on the wastewater pipeline 70. The wastewater solenoid valve 702 is controlled by a controller to open or close the wastewater outlet of the post-filter 102.

[0083] like Figure 1 As shown, in this embodiment, a drain pipe 80 is connected to the bottom of the water storage tank 201. The end of the drain pipe 80 furthest from the water storage tank 201 is connected to a wastewater pipe 70. A third drive pump 801 and a second check valve 802 are installed on the drain pipe 80, with the second check valve 802 located downstream of the third drive pump 801. When the water system is not used for an extended period, the water in the water storage tank 201 can be drained by turning on the third drive pump 801 and opening the second check valve 802, allowing for the re-storage of mineral water and improving its cleanliness. When the third drive pump 801 is turned off, the second check valve 802 closes the drain pipe 80 to prevent backflow of water.

[0084] Preferably, the inner cavity of the water storage tank 201 is equipped with a germicidal lamp for sterilizing the mineral water.

[0085] In another alternative embodiment, a drain outlet is provided at the bottom of the water storage tank, and a drain valve is installed at the drain outlet.

[0086] In this embodiment, the water flow direction of each waterway in the water system is as follows: Figure 1 As shown by the arrow in the image.

[0087] This embodiment also discloses a water purifier, which includes a water system with adjustable mineral content as described above.

[0088] In the description herein, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model 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.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
