Description

Technical Field

[0001] The present invention relates to the technical field of water purifiers, and particularly to a water purification machine water circuit system and a water purification machine using a diaphragm pump. Background Art

[0002] At present, most of the water purifiers on the market only filter raw water such as tap water to obtain pure water; if consumers want to obtain hot water, they need to be equipped with accessories such as kettles and pipeline machines to heat the pure water, and then obtain hot water. As time goes by, products that integrate the heating function into the water purifier appear on the market, which is simply called a combined water purifier with heating function. The main heating methods are instant heating (instant heat) and storing pure water (filtered water) in a hot water tank for heating.

[0003] For the hot water tank solution on the market, that is, the combined water purifier with heating function mainly uses a centrifugal pump to discharge the water in the hot water tank for users to use. This system has the following problems:

[0004] 1. Since the centrifugal pump has no self-priming ability, the centrifugal pump must be placed below the hot water tank, so that there is a height difference between the centrifugal pump and the hot water tank, so as to ensure that the water entering the centrifugal pump from the hot water tank has a certain pressure to avoid dry running. The centrifugal pump can only be set below the hot water tank, which greatly limits the layout of the entire system, is not conducive to the flexibility of the entire system, and will also increase the height of the water purifier.

[0005] 2. The centrifugal pump has a high rotation speed, so the centrifugal pump is sensitive to pressure, which will result in poor flow accuracy of the centrifugal pump in the combined water purifier with heating function system. In order to control the flow rate, a heat-resistant flow meter needs to be added to the system to feedback the flow information and adjust the rotation speed of the centrifugal pump in real time to ensure the flow accuracy. The heat-resistant flow meter needs to work normally in a high-temperature environment for a long time, so it has high requirements for its performance and its cost is high. The heat-resistant flow meter greatly increases the cost of the system, reduces the competitiveness of the product, and increases the complexity of the system.

[0006] 3. The hot water tank in the system using a centrifugal pump must have a large exhaust port to ensure that the hot water tank is connected to the atmosphere, so as to avoid the formation of a vacuum in the hot water tank after the hot water is discharged, which will lead to a decrease in the water pressure entering the water pump and exacerbate the dry running phenomenon of the water pump; the large exhaust port is also used to discharge the water vapor generated during the heating process of the hot water tank to avoid the occurrence of cavitation phenomenon caused by the water vapor entering the water pump. After the cavitation phenomenon occurs, the system noise will become larger and the flow rate will decrease, which will seriously affect the user experience. The larger the exhaust port, the lower the heat preservation performance of the hot water tank will be.

[0007] Therefore, it is urgent to solve the problems of low flexibility, high cost, and low heat preservation performance of the combined water purifier with heating function system in this field. Summary of the Invention

[0008] The main object of the present invention is to provide a water purification machine water circuit system and a water purification machine using a diaphragm pump, aiming to solve the problems of low flexibility, high cost, and low heat preservation performance of the pure heat system.

[0009] To achieve the above object, the water purification machine water circuit system using a diaphragm pump proposed by the present invention includes an inlet water circuit, a filtration module, an outlet water circuit, a heating water circuit, a hot water tank, and at least one diaphragm pump: the inlet end of the filtration module is connected to the outlet of the inlet water circuit; the inlet of the outlet water circuit is connected to the outlet end of the filtration module for supplying water to the outside; the inlet of the heating water circuit is connected to the upstream of the outlet water circuit; the hot water tank is arranged on the heating water circuit; the at least one diaphragm pump is arranged on the heating water circuit, and the diaphragm pump is arranged at the rear end of the hot water tank.

[0010] In an embodiment, the water purification machine water circuit system further includes a first return water circuit, one end of the first return water circuit is connected to the heating water circuit and is located at the rear end of the diaphragm pump, and the other end is connected to the hot water tank.

[0011] In an embodiment, the water purification machine water circuit system further includes an exhaust pipe circuit, one end of the exhaust pipe circuit is connected to the hot water tank, and the other end is used to communicate with the outside.

[0012] In an embodiment, the diaphragm pump is arranged at the bottom of the hot water tank; or, the diaphragm pump is arranged on one side of the hot water tank.

[0013] In an embodiment, a water level probe is arranged on the hot water tank; the water level probe extends into the hot water tank.

[0014] In an embodiment, the top of the hot water tank has an exhaust port connected to the exhaust pipe circuit, and the diameter of the exhaust port is in the range of 3 mm - 4.5 mm.

[0015] In an embodiment, a temperature detection module is installed on the top of the hot water tank; and / or, a temperature detection module is installed on the bottom wall of the hot water tank.

[0016] In an embodiment, the filtration module includes a composite filter element, a booster pump, and a reverse osmosis filter element; the composite filter element includes a pre-filter element and a post-filter element, the inlet of the pre-filter element is connected to the outlet of the inlet water circuit; the booster pump is respectively connected to the outlet of the pre-filter element and the inlet of the reverse osmosis filter element; the outlet of the reverse osmosis filter element is connected to the inlet of the post-filter element; the outlet of the post-filter element is connected to the outlet water circuit.

[0018] The present invention also provides a water purifier, which includes the above-mentioned water purifier water circuit system.

[0019] In the technical solution of the present invention, by replacing the centrifugal pump with a diaphragm pump, the self-priming ability of the water pump can be greatly improved. Therefore, the position of the diaphragm pump can be set arbitrarily, not limited to being set below the hot water tank, and can be set at other positions, which improves the flexibility of system design, can greatly reduce the layout difficulty of the system, and can reduce the height of the water purifier, thereby improving the competitiveness of the water purifier. The diaphragm pump is a positive displacement pump, and its flow accuracy can reach within 10%. Compared with the centrifugal pump with an accuracy of within 20%, this application can cancel the flow meter to greatly reduce the system cost, reduce the complexity of the system, and improve the competitiveness of the product. Due to the improvement of the self-priming ability of the diaphragm pump, its exhaust hole can be reduced by more than 20% without worrying about cavitation problems. The reduction of the exhaust hole can greatly improve the heat preservation performance of the hot water tank. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0030] At present, the integrated net heat machine on the market uses a hot water tank and a centrifugal pump for heating and water supply. The following problems exist in this system:

[0031] Since the centrifugal pump does not have self-priming ability, the centrifugal pump must be placed below the hot water tank, so that there is a height difference between the centrifugal pump and the hot water tank, so as to ensure that the water entering the centrifugal pump from the hot water tank has a certain pressure to avoid air extraction. The centrifugal pump can only be set below the hot water tank, which greatly limits the layout of the entire system, is not conducive to the flexibility of the entire system, and will also increase the height of the water purifier.

[0032] The rotational speed of a centrifugal pump is relatively high. Therefore, the centrifugal pump is sensitive to pressure, which results in poor flow accuracy of the centrifugal pump in the net heat system. To control the flow rate, it is necessary to add a heat-resistant flowmeter in the system to feedback the flow information and adjust the rotational speed of the centrifugal pump in real time to ensure the flow accuracy. The heat-resistant flowmeter needs to be used normally in a high-temperature environment for a long time. Therefore, it has high requirements for its performance and its cost is relatively high. The heat-resistant flowmeter greatly increases the cost of the system, reduces the competitiveness of the product, and increases the complexity of the system.

[0033] The hot water tank in the system using a centrifugal pump must have a large exhaust port to ensure the connection between the hot water tank and the atmosphere, thereby avoiding the formation of a vacuum in the hot water tank after the hot water is discharged, which leads to a decrease in the water pressure entering the water pump and exacerbates the phenomenon of the water pump running dry; the large exhaust port is also used to discharge the water vapor generated during the heating process of the hot water tank to avoid the occurrence of cavitation caused by the water vapor entering the water pump. After the cavitation phenomenon occurs, the system noise will increase and the flow rate will decrease, which will seriously affect the user experience. The larger the exhaust port, the lower the heat preservation performance of the hot water tank will be correspondingly.

[0034] Therefore, it is necessary to design a new water purification machine water circuit system to solve the problems of low flexibility, high cost, and low heat preservation performance of the water purification machine water circuit system.

[0035] The present invention proposes a water purification machine water circuit system using a diaphragm pump.

[0036] Please refer to Figure 1 As shown in the figure, in an embodiment of the present invention, the water purification machine water circuit system using a diaphragm pump includes an inlet water circuit 10, a filtration module 20, an outlet water circuit 30, a heating water circuit 40, a hot water tank 50, and at least one diaphragm pump 60. The inlet end of the filtration module 20 is connected to the outlet of the inlet water circuit 10. The inlet of the outlet water circuit 30 is connected to the outlet end of the filtration module 20 and is used for delivering water to the outside. The inlet of the heating water circuit 40 is connected to the upstream of the outlet water circuit 30. Both the hot water tank 50 and at least one diaphragm pump 60 are arranged on the heating water circuit 40, and the diaphragm pump 60 is arranged at the rear end of the hot water tank 50.

[0037] Specifically, the water purification machine waterway system of the present application is used in a water purification machine to provide hot water for users; it includes an inlet waterway 10, a filtration module 20, an outlet waterway 30, a heating waterway 40, a hot water tank 50, and a diaphragm pump 60. The inlet waterway 10 is used to introduce an external water source into the system, and the external water source can be a water source such as tap water. The water purification machine waterway system of the present application can process raw water through filtration, heating and other processes to provide clean hot water and normal temperature water. The filtration module 20 is used to filter the raw water to obtain a clean and potable water source. The inlet end of the filtration module 20, that is, the front end of the filtration module 20, is connected to the outlet of the inlet waterway 10, and the outlet end of the filtration module 20 is connected to the inlet of the outlet waterway 30. The outlet waterway 30 is used to transport the filtered clean normal temperature water to the user and to the heating waterway 40, and is heated through the heating waterway 40 to provide hot water for the user. Both the hot water tank 50 and the diaphragm pump 60 are arranged on the heating waterway 40. The bottom or other positions of the hot water tank 50 have a heating component. The hot water tank 50 is used to store the hot water heated by the heating component so as to quickly provide a large amount of hot water when needed, avoiding the need to reheat every time hot water is used, thereby improving the speed and efficiency of hot water supply. The number of diaphragm pumps 60 is set to at least one. The diaphragm pump 60 is arranged at the rear end of the hot water tank 50 and is used to pump out the water in the hot water tank 50 and send it to the outside for the user to pick up and use. The diaphragm pump 60 is a positive displacement pump, and its working principle is to realize the suction and discharge of fluid through the reciprocating movement of the diaphragm. It should be noted that since the diaphragm pump 60 is a positive displacement pump, the flow rate of the positive displacement pump is positively correlated with the volume of the pump. In some scenarios, a larger flow rate may be required. At this time, multiple diaphragm pumps 60 can be connected in parallel to achieve a larger flow rate.

[0038] The technical solution of the present invention is to provide a hot water tank 50 on the heating water circuit 40 and a diaphragm pump 60 at the rear end of the hot water tank 50. By replacing the centrifugal pump with the diaphragm pump 60, the self-priming ability of the water pump can be greatly improved. Therefore, the position of the diaphragm pump 60 can be set arbitrarily, not limited to being installed below the hot water tank 50, and can be set at other positions, which improves the flexibility of the system design, greatly reduces the layout difficulty of the system, and can reduce the height of the water purifier, thereby enhancing the competitiveness of the water purifier. The diaphragm pump 60 is a positive displacement pump, and its flow accuracy can reach within 10%, compared with the accuracy of the centrifugal pump within 20%. In this application, the flow meter 31 can be cancelled to greatly reduce the system cost, reduce the complexity of the system, and enhance the competitiveness of the product. The diaphragm pump 60 can change the flow pressure through simple adjustment to adapt to different scenarios and needs. For example, in a water purifier, users can adjust the flow rate of hot water according to their needs, and the diaphragm pump 60 can easily achieve this function, improving the flexibility of the system and the user experience. The working principle of the diaphragm pump 60 results in less noise and vibration during operation, which is particularly important for household or commercial water purifiers. Due to the improvement of the self-priming ability of the diaphragm pump 60, its exhaust hole can be reduced by more than 20% without worrying about cavitation problems. The reduction of the exhaust hole can greatly improve the heat preservation performance of the hot water tank 50.

[0039] Please refer to Figure 2 As shown, in an alternative embodiment, the water circuit system of the water purifier further includes a first return water circuit 70. One end of the first return water circuit 70 is connected to the heating water circuit 40, the other end is connected to the hot water tank 50, and the first return water circuit 70 is located at the rear end of the diaphragm pump 60.

[0040] Specifically, the end of the heating water circuit 40 of the water circuit system of the present application has a faucet, and users can turn on the faucet to receive hot water for use. Due to the certain check function of the rubber check valve 32 of the diaphragm pump 60, after the user finishes taking water from the faucet, there will be residual water in the pipeline between the faucet and the diaphragm pump 60. When the user turns on the faucet next time, the residual water is taken by the user. Since the residual water is not insulated, it will affect the user experience. In this application, a first return water circuit 70 is further provided at the rear end of the diaphragm pump 60. One end of the first return water circuit 70 is connected to the hot water tank 50, the other end is connected to the heating water circuit 40, and the first return water circuit 70 is between the diaphragm pump 60 and the faucet. The first return water circuit 70 is used to send the residual water at the rear end of the diaphragm pump 60 into the hot water tank 50 for heat preservation and for the next use.

[0041] Please refer to again Figure 2 As shown, in an alternative embodiment, the water circuit system of the water purifier further includes a second return water circuit 90. One end of the second return water circuit 90 is connected to the water outlet circuit 30, and the other end is connected to the filtration module 20.

[0042] Specifically, the end of the water outlet waterway 30 also has a faucet for receiving water. There will be residual water in the water outlet waterway 30 before the faucet, and this section of residual water may be stored for a long time, such as overnight water. At this time, the second return waterway 90 can be used to recycle the water in this section and filter it again through the filtration module 20 to filter it into fresh pure water for users to drink. A return valve and a one-way valve 32 are provided on the second return waterway 90 to recycle the residual water on the water outlet waterway 30 and filter it again.

[0043] In an optional embodiment, the water purification machine waterway system further includes an exhaust pipeline 80. One end of the exhaust pipeline 80 is connected to the hot water tank 50, and the other end is used to communicate with the outside. The top of the hot water tank 50 has an exhaust port for connecting the exhaust pipeline 80, and the diameter of the exhaust port is between 3 mm and 4.5 mm.

[0044] Specifically, the water purification machine waterway system in this embodiment further includes an exhaust pipeline 80 connected to the hot water tank 50. The exhaust pipeline 80 is connected to the top of the hot water tank 50 to communicate the inside of the hot water tank 50 with the atmosphere, avoiding the formation of a vacuum after the hot water in the hot water tank 50 is discharged, which causes the water pressure entering the diaphragm pump 60 to decrease and exacerbates the dry running phenomenon of the diaphragm pump 60; the exhaust pipeline 80 can also discharge the water vapor generated during the heating process of the hot water tank 50 to avoid cavitation caused by it entering the diaphragm pump 60. In some embodiments, the exhaust pipeline 80 is made of transparent food-grade silicone hose. One end of the exhaust pipeline 80 is installed on the top of the hot water tank 50 by threaded connection, and the other end is connected to the outside through a small one-way valve 32.

[0045] The top of the hot water tank 50 has an exhaust port for connecting the exhaust pipeline 80. In this embodiment, the diameter of the exhaust port is set between 3 mm and 4.5 mm. In this application, by setting the exhaust port, a vacuum is prevented from forming in the hot water tank 50, thereby ensuring the stable water inlet pressure of the diaphragm pump 60 and avoiding the dry running phenomenon. By setting the diameter of the exhaust port within this range, it can ensure that the gas passes through at an appropriate speed, neither too fast resulting in excessive pressure nor too slow resulting in gas accumulation; nor will it affect the heat preservation performance of the hot water tank 50. In this application, the diaphragm pump 60 is used to replace the centrifugal vane pump. Since the self-priming ability of the diaphragm pump 60 is improved, the cross-sectional area of the exhaust hole can be reduced by more than 20% without worrying about cavitation problems, and the heat preservation performance of the hot water tank 50 can be greatly improved. The diameter of the exhaust port can be controlled by precision machining technology to ensure that it is within the specified range. By controlling the diameter range of the exhaust port, the heat preservation performance of the hot water tank 50 is ensured, thereby improving the operating efficiency and reliability of the overall system.

[0046] In an optional embodiment, the diaphragm pump 60 is arranged on one side of the hot water tank 50, or the diaphragm pump 60 is arranged at the bottom of the hot water tank 50.

[0047] Specifically, in this application, the diaphragm pump 60 is arranged on the side of the hot tank 50, or the diaphragm pump 60 is arranged below the hot tank 50. The technical features of these two position arrangements are aimed at optimizing the installation position of the pump to better realize the function of the pump. Arranging the diaphragm pump 60 on the side of the hot tank 50 enables the operator to more easily access the pump body for necessary inspections and maintenance work. Therefore, this design facilitates installation and maintenance. The side-mounted diaphragm pump 60 can also reduce the interference of the pump body on the bottom structure of the hot tank 50, thereby maintaining the structural integrity of the bottom of the hot tank 50. This setting method can make the pump more stable during operation and reduce failures caused by vibration or other factors. Specifically, the diaphragm pump 60 can be fixed to one side of the hot tank 50 through a bracket and connected to the outlet of the hot tank 50 and the outlet of the heating water circuit 40 through pipes. In this way, maintenance and repair can be conveniently carried out without affecting the normal operation of the pump.

[0048] It should be noted that the diaphragm pump 60 can also be arranged at other positions of the hot tank 50 according to requirements. The specific installation position can be set according to the layout of the system to improve the flexibility of the system and ensure the performance of the overall system.

[0049] Please refer to Figure 1 and Figure 2 As shown, in an alternative embodiment, a water level probe 51 is provided on the hot tank 50, and the water level probe 51 extends into the hot tank 50.

[0050] Specifically, the water level probe 51 is a sensor, usually used to monitor the liquid level of the fluid inside the container. Multiple water level probes 51 are installed on the hot tank 50 of this application. For example, three water level probes 51 are used. The three water level probes 51 extend into the hot tank 50 to different depths. One water level probe 51 extends to a position close to the bottom wall of the hot tank 50, another water level probe 51 extends to the middle position of the hot tank 50, and the last water level probe 51 extends to a position close to the top of the hot tank 50. The water volume in the hot tank 50 can be accurately monitored through the three water level probes 51. When it is detected that the water volume in the hot tank 50 is less than the preset value, a water replenishment operation can be triggered. It can send a signal to the control system to trigger the water replenishment operation to maintain the liquid level in the hot tank 50 within the normal range.

[0051] Please refer to Figure 2 As shown, in an alternative embodiment, a temperature detection module 52 is installed on the top of the hot tank 50; and / or, a temperature detection module 52 is installed on the bottom wall of the hot tank 50.

[0052] Specifically, in this embodiment, the top of the hot water tank 50 can be on the lid of the hot water tank 50 or at a position on the side wall of the hot water tank 50 near the lid. A temperature detection module 52 for detecting the internal temperature of the hot water tank 50 is provided at the top of the hot water tank 50. Setting the temperature detection module 52 at the top of the hot water tank 50 can quickly respond to the temperature change at the top of the hot water tank 50. A temperature detection module 52 is also installed on the bottom wall of the hot water tank 50, which can provide temperature information closer to the medium at the bottom of the hot water tank 50. This is very important for understanding the heating state of the bottom wall of the hot water tank 50, monitoring possible thermal stratification, or ensuring that the water also reaches the required temperature at the bottom. Especially in some scenarios that require uniform heating, the bottom temperature detection module 52 can help ensure a uniform temperature distribution throughout the hot water tank 50.

[0053] In terms of implementation, the temperature detection module 52 can adopt a variety of sensor technologies, such as thermocouples, thermistors, or semiconductor temperature sensors. Specifically, thermocouples have the characteristics of fast response and high precision and are suitable for real-time monitoring of water temperature changes; thermistors have lower costs and are suitable for large-scale applications; semiconductor temperature sensors can provide higher integration and stability. Further, the temperature detection module 52 can transmit the detected temperature data to the control system wirelessly or wiredly, and the control system makes corresponding adjustments and controls according to the temperature data. In addition, the installation position of the temperature detection module 52 can be adjusted according to actual needs. For example, multiple temperature detection modules 52 are set at different heights of the hot water tank 50 to achieve more accurate temperature monitoring.

[0054] In an optional embodiment, the filtration module 20 includes a composite filter element 21, a booster pump 22, and a reverse osmosis filter element 23. The composite filter element 21 includes a pre-filter element 211 and a post-filter element 212. The outlet of the water inlet path 10 is connected to the inlet of the pre-filter element 211. The booster pump 22 is respectively connected to the inlet of the reverse osmosis filter element 23 and the outlet of the pre-filter element 211. The outlet of the reverse osmosis filter element 23 is connected to the inlet of the post-filter element 212, and the outlet of the post-filter element 212 is connected to the water outlet path 30.

[0055] Specifically, the filtration module 20 of the present application includes a composite filter element 21, a booster pump 22, and a reverse osmosis filter element 23 that are connected to each other. The composite filter element 21 includes a pre-filter element 211 and a post-filter element 212. The pre-filter element 211 is used to filter raw water, and the post-filter element 212 is used for further filtration and to impart a certain taste. The pre-filter element 211 is mainly responsible for initially filtering large particulate impurities, suspended solids, and some organic substances in the raw water. This step is the basis of the purification process and prepares for subsequent finer filtration. The pre-filter element 211 can be made of various materials such as PP cotton and activated carbon, which have good adsorption and filtration properties. On the basis of the initial filtration by the pre-filter element 211, the post-filter element 212 further removes fine particles, residual organic substances, and possible peculiar smells and abnormal colors in the water. In addition, the post-filter element 212 can also add minerals or substances to improve the taste, giving the purified water a better taste and flavor. The post-filter element 212 can be made of finer activated carbon, ion exchange resin, or special mineralization materials, etc., to ensure that the water quality reaches the best state in terms of taste and safety. The booster pump 22 is located between the composite filter element 21 and the reverse osmosis filter element 23, and its main function is to provide sufficient water pressure to drive the reverse osmosis process. Since the reverse osmosis membrane of the reverse osmosis filter element 23 requires a relatively high pressure to effectively separate salts, heavy metals, and other small molecule impurities in the water, the presence of the booster pump 22 is crucial.

[0056] The specific flow direction of the raw water in the present application is as follows: The raw water is first transported from the inlet water path 10 to the inlet of the pre-filter element 211 of the composite filter element 21 and undergoes the filtration of the pre-filter element 211; then the water flows from the outlet of the pre-filter element 211 to the booster pump 22, undergoes the boosting of the booster pump 22, flows to the inlet of the reverse osmosis filter element 23, undergoes the filtration of the reverse osmosis filter element 23, flows out from the outlet of the reverse osmosis filter element 23, and flows to the post-filter element 212 of the composite filter element 21. After undergoing the fine filtration and taste imparting of the post-filter element 212, it is then sent from the outlet of the post-filter element 212 to the outlet water path 30.

[0057] In an optional embodiment, a water quality detection module 53 and a temperature detection module 52 are also provided between the composite filter element 21 and the reverse osmosis filter element 23. By arranging the water quality detection module 53 and the temperature detection module 52 between the composite filter element 21 and the reverse osmosis filter element 23 in the present application, dual monitoring of water quality and temperature during the filtration process can be achieved, which not only improves the intelligent level of the system but also increases the safety and stability of the system. When the water quality or temperature is abnormal, the system can respond quickly and take appropriate measures to ensure that the output water quality always meets the standards and at the same time extend the service life of the filter element.

[0058] In an optional embodiment, a flow meter 31, a check valve 32, a high-pressure switch 33, and a pipeline machine 34 are sequentially arranged on the water outlet waterway 30; and / or, the water purification machine waterway system further includes a waste water waterway 20a, and the waste water waterway 20a is connected to the waste water outlet of the reverse osmosis filter element 23.

[0059] In this application, by arranging the flow meter 31, the check valve 32, the high-pressure switch 33, and the pipeline machine 34 on the water outlet waterway 30, precise control and management of the water flow are achieved.
