Description

Technical Field

[0001] This utility model relates to the field of water purification equipment technology, and in particular to a heat storage type integrated water purification and heating machine. Background Technology

[0002] A thermal storage-type water purifier and heat exchanger is a water purification device that pre-stores purified water prepared by an RO filter in a heating tank and then heats it to boiling, conveniently meeting users' needs for both hot and warm water. If hot water is needed, it is supplied directly from the heating tank; if warm water is needed, it is generally obtained by mixing boiled water and raw water. Different temperatures of warm water can be obtained by changing the mixing ratio of boiled water and raw water. The advantages of a thermal storage-type water purifier and heat exchanger are its large output of both hot and warm water, and the hot water it produces undergoes a genuine boiling process.

[0003] However, due to the characteristics of RO filters, the raw water flow rate varies under different temperatures and inlet water pressures. Lower temperatures and inlet pressures result in a smaller flow rate at room temperature; conversely, higher temperatures and inlet pressures lead to a larger flow rate. Under different seasons and tap water pressures, both the room temperature and flow rate of the raw water vary. Since the warm water in a storage-type integrated water purifier is obtained by mixing boiling water and raw water, the resulting warm water temperature fluctuates significantly, leading to a large error and a poor user experience. Furthermore, external factors such as the duration of RO filter use can also cause significant errors in the mixed warm water temperature, sometimes exceeding 10℃, further contributing to a poor user experience.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] like Figure 1 As shown, this utility model provides a thermal storage-type integrated water purifier and heat purifier. This unit not only has a purification function but can also provide users with boiling water (approximately 100℃), warm water, and room temperature water according to their needs. It should be noted that the room temperature water temperature is determined by the working environment of the unit, while the warm water temperature is between room temperature and boiling water. While existing thermal storage-type integrated water purifiers can also provide warm water, the temperature difference between the provided water and the user's desired temperature is significant, sometimes reaching as high as 10℃. The thermal storage-type integrated water purifier and heat purifier provided by this utility model effectively reduces the error in the warm water outlet temperature.

[0034] Specifically, the storage-type integrated water purifier and heat purifier disclosed in this utility model includes a water purification mechanism 100, a heating mechanism 200, and a water outlet mechanism 300. The water purification mechanism 100 is a key component of the storage-type integrated water purifier and heat purifier that performs the water purification function. It can reduce harmful substances in the raw water. The water purification mechanism 100 includes a pre-filter 110 and an RO filter 120 connected in sequence. The first water outlet 101 of the pre-filter 110 is used to connect to an external water source that can provide raw water. The raw water is filtered by the pre-filter 110 to form purified water. The purified water outlet 104 of the pre-filter 110 and the water inlet of the RO filter 120 are connected through a first water passage 130. A variable frequency booster pump 140 is provided on the first water passage 130. The purified water is turned into pure water by passing through the RO filter 120. The heating mechanism 200 is a component of the heat storage type water purifier that performs the heating function. It can heat the pure water filtered by the water purification mechanism 100 to meet the user's demand for hot water. The water inlet of the heating mechanism 200 is connected to the pure water outlet 102 of the water purification mechanism 100. The heating mechanism 200 is equipped with a first temperature detection mechanism 210. The first temperature detection mechanism 210 can obtain the real-time temperature of the hot water in the heating mechanism 200. The temperature obtained by the first temperature detection mechanism 210 is defined as T1. The first inlet 301 of the water outlet mechanism 300 is connected to the outlet of the heating mechanism 200 through the second water passage 410. The second water passage 410 is equipped with a hot water pump 500 with PWM duty cycle adjustment function. Hot water with a first temperature (i.e., T1) in the heating mechanism 200 can be supplied to the water outlet mechanism 300 through the second water passage 410. The second inlet 302 of the water outlet mechanism 300 is connected to the pure water outlet 102 of the water purification mechanism 100 through the third water passage 420. The third water passage 420 is equipped with a second temperature detection mechanism 600. The temperature that can be obtained by the second temperature detection mechanism 600 is T2. The second temperature (i.e., T2) pure water that has been filtered by the water purification mechanism 100 and has not been heated can be supplied to the water outlet mechanism 300 through the third water passage 420. The second temperature is lower than the first temperature. The water outlet mechanism 300 is equipped with a mixing chamber for mixing hot water at the first temperature and pure water at the second temperature. In the mixing chamber, hot water at the first temperature and pure water at room temperature at the second temperature are mixed to obtain warm water. The temperature of this warm water (i.e., the mixing temperature) is defined as T3. T3 is also the expected temperature of the warm water that the user wants.

[0035] It should be noted that a hot water pump 500 with PWM duty cycle adjustment function, installed on the second water channel 410, provides power for drawing hot water from the heating mechanism 200. Since the hot water pump 500 has PWM duty cycle adjustment, the output hot water flow rate can be controlled by inputting different duty cycles to the hot water pump 500. Specifically, after the user determines the desired mixing water temperature, the duty cycle of the hot water pump 500 can be determined according to the corresponding "Mixing Water Temperature T3 - Duty Cycle - Flow Rate Table". Therefore, the hot water flow rate that the heating mechanism 200 can provide to the water supply mechanism 300 is determined, and the hot water flow rate is defined as V1.

[0036] Since the temperature T3 of the warm water satisfies the following formula: In this formula, T3 is a set value, T1 can be obtained through the first temperature detection mechanism 210, V1 is determined by consulting the "Mixed Water Temperature T3 - Duty Cycle - Flow Rate Table" of the hot water pump 500, and T2 can be obtained through the second temperature detection mechanism 600. Therefore, by calculating both sides of the equation, the specific value of V2 (i.e., the flow rate of ambient temperature pure water) can be obtained. According to the "Flow Rate and Speed ​​Relationship Table" corresponding to the variable frequency booster pump 140, the speed corresponding to the V2 flow rate can be obtained. By controlling the variable frequency booster pump 140 to adjust to the corresponding speed, the mixed water temperature flowing out of the water outlet mechanism 300 can be T3 or a very small error of warm water. This storage-type integrated water purifier provides warm water with a small temperature error, better meeting user expectations and providing a superior user experience.

[0037] It should be noted that once the type of hot water pump 500 is determined, its "mixing temperature T3-duty cycle-flow table" can be obtained; once the variable frequency booster pump 140 is determined, its "flow rate and speed relationship table" can be obtained.

[0038] In a specific embodiment, assuming a 1200G water purifier is used and the user requires a water temperature of 45°C, the required hot water flow rate is defined as approximately V1 = 1.2 L / min based on basic calculations. If the hot water temperature inside the heating unit 200 is T1 = 95°C and the ambient pure water temperature is T2 = 20°C, these data are substituted into the formula: Then we can get: Calculations show that the required flow rate of pure water at room temperature is V2 = 2.4 L / min. By referring to Table 1 below, we can find that the speed of the variable frequency booster pump 140 is approximately 680 r / min. By directly inputting this value into the electronic control of the variable frequency booster pump 140, a precisely temperature-controlled 45℃ warm water can be produced.

[0039] Table 1

[0040]

[0041] In one specific embodiment, the "Mixing Temperature T3 - Duty Cycle - Flow Rate Table" of the hot water pump 500 is shown in Table 2 below:

[0042] Table 2

[0043]

[0044] In some embodiments, the hot water flow rate of the hot water pump 500 with PWM duty cycle regulation function is adjustable within the range of 1.5L / min to 3.5L / min under normal operating conditions. Optionally, the hot water pump 500 is a three-phase DC brushless water pump with PWM regulation and signal feedback functions. The specific structure, PWM regulation principle, and signal feedback principle of the hot water pump 500 with PWM duty cycle regulation function are existing technologies and will not be described in detail here.

[0045] In some embodiments, the rotational speed of the variable frequency booster pump 140 is adjustable within the range of 300 r / min to 1450 r / min. Optionally, the variable frequency booster pump 140 adopts a 310V booster pump + drive board configuration. Different power inputs to the 310V booster pump can be achieved through the drive board to change the booster pump speed, thereby enabling the output of different ambient temperature pure water flow rates. The specific structure of the variable frequency booster pump 140 is prior art and will not be detailed here. In a specific embodiment, the technical parameters of the 310V variable frequency booster pump 140 are shown in Table 3 below.

[0046] Table 3

[0047]

[0048] In some embodiments, both the first temperature detection mechanism 210 and the second temperature detection mechanism 600 are NTC temperature sensors. NTC temperature sensors have advantages such as high sensitivity, high accuracy, good stability, and low cost. Of course, in other embodiments, the first temperature detection mechanism 210 and the second temperature detection mechanism 600 may also use other types of temperature sensors, such as thermocouple temperature sensors, PTC temperature sensors, etc.

[0049] In some embodiments, the pre-filter 110 is a PCB filter element, which is a two-in-one pre-filter composite element integrating PP cotton and carbon rod. It can perform physical filtration and chemical adsorption on raw water. Physical filtration can remove visible particulate matter from the raw water, while chemical adsorption can remove residual chlorine, improving the taste and odor of the water. Using a PCB filter element as the pre-filter 110 results in better purification of raw water. Of course, in other embodiments, other filter elements can be used as the pre-filter 110, and it is not limited to a PCB filter element.

[0050] In some embodiments, the pre-filter 110 and the RO filter 120 are integrated together, and the pure water outlet 102 is formed on the pre-filter 110. The water purification mechanism 100 has a primary filtration mode and a secondary filtration mode. In the primary filtration mode, the first inlet 101 of the pre-filter 110 is directly connected to the pure water outlet 102, and the raw water, after being filtered by the pre-filter 110, flows directly to the water outlet mechanism 300 through the pure water outlet 102. In the secondary filtration mode, the raw water passes through the pre-filter 110 and the RO filter 120 sequentially and is then discharged through the pure water outlet 102. (Continuing to refer to...) Figure 1 As shown, the pre-filter 110 is provided with a second water inlet 103, the outlet of the RO filter 120 is connected to the pure water outlet 102 formed on the pre-filter 110, and the outlet of the RO filter 120 and the second water inlet 103 are connected through a fourth water passage 430.

[0051] Users can choose between a primary filtration mode or a secondary filtration mode according to their water needs. If the primary filtration mode is selected, the inlet of the pre-filter 110 is directly connected to the pure water outlet 102 on it. If the secondary filtration mode is selected, the first water inlet 101 of the pre-filter 110 is connected to its purified water outlet 104, and the second water inlet 103 is connected to its pure water outlet 102.

[0052] The RO filter element 120 also has a wastewater outlet, which discharges wastewater through a wastewater discharge passage 460. A wastewater valve 860 is installed on the wastewater discharge passage 460. The wastewater valve 860 can control the opening and closing of the wastewater discharge passage 460. Optionally, the wastewater valve 860 is a solenoid valve.

[0053] The water inlet of the heating mechanism 200 is connected to the pure water outlet 102 of the water purification mechanism 100 via a fifth water passage 440, and a water supply valve 810 is provided on the fifth water passage 440. Optionally, the water supply valve 810 is a solenoid valve.

[0054] Optionally, the heating mechanism 200 is a hot tank. In addition to having a water inlet and a water outlet, the hot tank is also provided with an exhaust port, which is connected to the air inlet of the water outlet mechanism 300 through an exhaust pipe 470.

[0055] Continue to refer to Figure 1 As shown, the heat storage type integrated water purifier also includes a pure water main outlet 480. One end of the pure water main outlet 480 is connected to the pure water outlet 102 of the water purification unit 100, and the other end is connected to both the third water channel 420 and the fifth water channel 440. By using the pure water main outlet 480, the water circuit can be simplified, avoiding the need to open too many pure water outlets on the water purification unit 100, thereby avoiding the additional costs incurred in modifying the water purification unit 100.

[0056] Optionally, a first TDS meter 910 is installed on the pure water main outlet 480. The first TDS meter 910 is an electronic device that indirectly measures the TDS value using the principle of conductivity. The TDS value of the pure water in the pure water main outlet 480 can be obtained through the first TDS meter 910. The TDS value can be used to determine whether the water purification unit 100 is working properly. For example, the TDS value of pure water after filtration by the RO filter 120 is generally between 1 and 50. If the TDS value obtained by the first TDS meter 910 exceeds this range, it can be determined that the RO filter 120 may have too long a service life and needs to be replaced or has malfunctioned. At this time, the alarm mechanism of the heat storage type water purifier can issue an alarm to remind the user to deal with it in time.

[0057] In some embodiments, a first check valve 820 is provided on the pure water main outlet 480. The first check valve 820 ensures that the pure water in the pure water main outlet 480 can only flow from the pure water outlet 102 to the heating mechanism 200 or the water outlet mechanism 300, thus preventing pure water backflow.

[0058] Continue to refer to Figure 1 As shown, the heat storage type integrated water purifier also includes a pure water flushing channel 450. One end of the pure water flushing channel 450 is connected to the main pure water outlet channel 480, and the other end is connected to the first water channel 130. The connection point is located upstream of the variable frequency booster pump 140. A return valve 840 is provided on the pure water flushing channel 450. By setting up the pure water flushing channel 450, the pure water in the pure water flushing channel 450 can be used to flush the RO filter element 120, resulting in a better flushing effect on the RO filter element 120.

[0059] In some embodiments, a second check valve 830 is provided on the pure water rinsing water path 450. The second check valve 830 ensures that the pure water in the pure water main outlet path 480 can only flow from the pure water outlet 102 to the pure water rinsing water path 450, thus preventing pure water backflow.

[0060] In some embodiments, the connection point between the pure water flushing water path 450 and the pure water main outlet path 480 is located upstream of the first TDS meter 910 and the first one-way valve 820.

[0061] Continue to refer to Figure 1 As shown, a second TDS meter 920 is installed on the first water channel 130. The second TDS meter 920 is also an electronic device that indirectly measures the TDS value using the principle of conductivity. The TDS value of the purified water in the first water channel 130 can be obtained through the second TDS meter 920. By comparing this TDS value with the TDS value obtained by the first TDS meter 910, the water purification effect of the RO filter 120 can be determined.

[0062] Continue to refer to Figure 1As shown, a first flow detection mechanism 710 is provided on the second water channel 410. The first flow detection mechanism 710 is used to monitor the real-time flow rate V0 of the hot water output from the heating mechanism 200. By comparing the real-time flow rate V0 with the V1 (also the expected flow rate) determined by the hot water pump 500, it can be determined whether the hot water pump 500 is working normally. If the difference between the real-time flow rate V0 and the expected flow rate V1 is within the error range, it can be determined that the hot water pump 500 is working normally. If the difference between the real-time flow rate V0 and the expected flow rate V1 is outside the error range, it can be determined that the hot water pump 500 has malfunctioned or that the control of the hot water pump 500 has malfunctioned.

[0063] Optionally, the first flow detection unit 710 is a hot water flow meter.

[0064] Continue to refer to Figure 1 As shown, a second flow detection mechanism 720 is provided on the fourth water channel 430. The second flow detection mechanism 720 is used to monitor the real-time flow rate V4 of the room temperature pure water flowing from the RO filter element 120 to the pre-filter element 110. By comparing the real-time flow rate V4 with the V3 (also the expected flow rate) determined by the variable frequency booster pump 140, it can be determined whether the variable frequency booster pump 140 is working normally. If the difference between the real-time flow rate V4 and the expected flow rate V3 is within the error range, it can be determined that the variable frequency booster pump 140 is working normally. If the difference between the real-time flow rate V4 and the expected flow rate V3 is outside the error range, it can be determined that the variable frequency booster pump 140 has malfunctioned or that the control of the variable frequency booster pump 140 has malfunctioned.

[0065] Continue to refer to Figure 1 The first water inlet 101 of the pre-filter element 110 is connected to the water source through a water inlet passage. A water inlet valve 870 is provided on the water inlet passage, which can control the opening and closing of the water inlet passage. Optionally, the water inlet valve 870 is a solenoid valve.

[0066] A normal temperature water valve 850 is provided on the third water passage 420. The normal temperature water valve 850 can control the opening and closing of the third water passage 420, thereby meeting the user's need for hot water supplied by the heating mechanism 200. Optionally, the normal temperature water valve 850 is a solenoid valve.

[0067] Optionally, the water outlet mechanism 300 is a touchscreen faucet. Users can input the mixing water temperature T3 to the control mechanism via the touchscreen faucet as needed.

[0068] The integrated heat storage and purification unit also includes a control mechanism, which can be a centralized or distributed controller. For example, the controller can be a single microcontroller or a combination of multiple distributed microcontrollers. The microcontroller can run a control program to control the inlet valve 870, the ambient temperature water valve 850, the water purification mechanism 100, the heating mechanism 200, the hot water pump 500, the variable frequency booster pump 140, the return valve 840, the water supply valve 810, the wastewater valve 860, etc., to achieve their respective functions.

[0069] This integrated heat storage and purification unit has the following advantages:

[0070] 1. The 500 hot water pump has a large flow rate and a wide adjustable PWM flow range, which can mix more levels of warm water;

[0071] 2. The variable frequency booster pump 140 can achieve different speeds through the variable frequency control of the driver, thereby outputting room temperature water at different flow rates. It has a wide speed range and can be used for short-term overclocking.

[0072] 3. By monitoring the actual hot water flow rate through a hot water flow meter, the variable frequency booster pump 140 can be automatically adjusted in real time using program logic to ensure the accuracy of the warm water temperature.

[0073] 4. The flow formula derived by combining theory and practice can adapt to different inlet water pressures and tap water temperatures, truly achieving accurate temperature control regardless of the situation.

[0074] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
