[0026] Reference below Figure 1 The drinking water device 100 according to an embodiment of the present invention is described.

[0027] According to the drinking water device 100 of the first embodiment of the utility model, for example, the drinking water device 100 can be a water purifier, a drinking water purifier, or a water-using device with a heating function or a cooling function.

[0028] The drinking water device 100 includes a purification module 1, a hot water tank 8 and a faucet 9. The drinking water device 100 is integrated with the purification module 1. The purification module 1 can purify the water source, remove impurities, microorganisms and other harmful substances in the water, and ensure the safety of drinking water. For example, the purification module 1 can be a filter element. The purified water flows to the hot water tank 8, which can heat the water and store the heated water. When the user needs to drink hot water, he can get water through the faucet 9; the storage-type drinking water device can have lower power than the instant hot drinking water device, which can save energy. The drinking water device 100 can realize an integrated process from source purification to heating by filtering the water source and heating and storing the filtered water, thereby improving the convenience of use.

[0029] The drinking water device 100 further includes an inlet flow path 2, an outlet flow path 3 and a warm water flow path 4. The inlet flow path 2 is connected to the water inlet end of the purification module 1, and the water source can flow to the purification module 1 through the inlet flow path 2. For example, an inlet valve 21 is provided on the inlet flow path 2, and the inlet valve 21 is used to connect or close the inlet flow path 2. A three-way valve 22 can be provided at one end of the inlet flow path 2 away from the purification module 1. One flow path of the three-way valve 22 is connected to the purification module 1, and the other two flow paths can be used to provide unpurified water sources, such as taps or water heaters. A filter can be provided in the three-way valve 22, and the filter is used to filter out large particles or other impurities.

[0030] The water outlet flow path 3 includes a first flow path 31 and a second flow path 32 in parallel. The first flow path 31 is connected between the purification module 1 and the hot water tank 8. The water filtered by the purification module 1 can flow to the hot water tank 8 through the first flow path 31, and the hot water tank 8 can heat the water. The water heated by the hot water tank 8 can flow to the warm water flow path 4, and the warm water flow path 4 can be connected with the second flow path 32. The water flowing in the second flow path 32 is the water filtered by the purification module 1. The water filtered by the purification module 1 can be mixed with hot water in the warm water flow path 4. The mixed warm water can reach the temperature of direct drinking by the user. The other end of the warm water flow path 4 is connected to the warm water inlet end of the faucet 9, and the warm water flows out through the faucet 9. The warm water flow path 4 has a certain length. The water filtered by the purification module 1 and the hot water can be fully mixed in the warm water flow path 4 to avoid not being fully mixed directly at the faucet 9, which affects the user's experience.

[0031] For example, when the user only needs to drink water at room temperature, the hot water in the hot water tank 8 does not need to flow to the warm water flow path 4, and only the room temperature water in the second flow path 32 flows to the warm water flow path 4; or, when warm water of a specific temperature is required, the flow rate of the hot water tank 8 to the warm water flow path 4 and the flow rate of the room temperature water in the second flow path 32 to the warm water flow path 4 can be adjusted, and they can be fully mixed in the warm water flow path 4 to achieve the temperature value required by the user.

[0032] For example, a water replenishment valve 311 is provided on the first flow path 31. The water replenishment valve 311 automatically monitors and maintains the pressure inside the hot water tank 8 to be no less than a preset value. When the pressure of the hot water in the hot water tank 8 drops below a set threshold, the water replenishment valve 311 will automatically open, allowing the water in the first flow path 31 to be replenished into the hot water tank 8; once the pressure of the hot water tank 8 returns to the set value, the water replenishment valve 311 will automatically close and stop replenishing water.

[0033] A first one-way valve 323 is disposed on the second flow path 32 , and the first one-way valve 323 is used to control the second flow path 32 to be connected or closed.

[0034] According to the drinking water device 100 of the embodiment of the utility model, one end of the warm water flow path 4 is connected to the hot water tank 8 and the second flow path 32 respectively. The normal temperature water in the second flow path 32 and the hot water in the hot water tank 8 can be fully mixed in the warm water flow path 4, avoiding the inability to fully mix directly at the faucet 9, thereby improving the user experience.

[0035] According to some embodiments of the present invention, referring to Figure 1 The drinking water equipment 100 also includes a first temperature detection component 81, a water pump 51 and a first flow meter 52. The first temperature detection component 81 is used to obtain the water temperature in the hot water tank 8. The water pump 51 is used to pump out the hot water in the hot water tank 8. The water pump 51 can adjust the flow rate of the hot water in the hot water tank 8 pumped into the hot water flow path 4. The first flow meter 52 is used to obtain the water outlet flow rate of the hot water tank 8.

[0036] The drinking water device 100 further includes a second temperature detection member 13, a solenoid valve 322 and a second flow meter 321. The second temperature detection member 13 is used to obtain the water temperature in the second flow path 32. The solenoid valve 322 is used to control the flow in the second flow path 32. The solenoid valve 322 can be used to control the opening or closing of the second flow path 32 and can also adjust the flow in the second flow path 32. The solenoid valve 322 responds to an electrical signal (usually a signal from a controller) to operate and can be quickly opened or closed without manual intervention. It is very suitable for systems that require automatic adjustment, and improves the intelligence level of the drinking water device 100. The second flow meter 321 is used to obtain the flow in the second flow path 32.

[0037] The drinking water device 100 further includes a third temperature detection component, which is used to obtain the water temperature in the warm water flow path 4 .

[0038] By setting the required temperature of warm water, the user can transmit an electrical signal to the control system. The control system can detect the water temperature of the normal temperature water in the second flow path 32 and the water temperature of the hot water in the hot water tank 8 respectively through the first temperature detection component 81 and the second temperature detection component 13, and adjust the water pump 51 and the solenoid valve 322 according to the detected water temperature to control the normal temperature water flow rate and the hot water flow rate flowing into the warm water flow path 4. The normal temperature water flow rate and the hot water flow rate can be obtained through the first flow meter 52 and the second flow meter 321, and the normal temperature water flow rate and the hot water flow rate flowing into the warm water flow path 4 can be detected. By fully mixing the normal temperature water and hot water in the warm water flow path 4, the third temperature detection component can detect the temperature of the warm water in the warm water flow path 4 to achieve the warm water temperature required by the user.

[0039] According to some embodiments of the present invention, referring to Figure 1The drinking water device 100 also includes a hot water flow path 5, which is used to connect the warm water flow path 4 and the hot water tank 8. The hot water in the hot water tank 8 is transported to the warm water flow path 4 through the hot water flow path 5, so that the hot water can be effectively and quickly transported from the hot water tank 8 to the warm water mixing point.

[0040] The hot water tank 8 is provided with a first temperature detection element 81, which can directly detect the temperature of the hot water in the hot water tank 8, thereby improving the accuracy of the first temperature detection element 81 in detecting the temperature of the hot water in the hot water tank 8. The hot water flow path 5 is provided with a water pump 51 and a first flow meter 52, and the water pump 51 is located between the first flow meter 52 and the hot water tank 8. After the water pump 51 pumps the hot water in the hot water tank 8 into the hot water flow path 5, the first flow meter 52 is used to detect the content of the hot water pumped into the hot water flow path 5, thereby improving the accuracy of the first flow meter 52 in detecting the content of the hot water in the hot water flow path 5.

[0041] A second temperature detection member 13 is provided in the purification module 1, and the second temperature detection member 13 is used to detect the temperature of the normal temperature water flowing through the purification module 1. The second flow path 32 is provided with an electromagnetic valve 322 and a second flow meter 321, which can directly control the flow in the second flow path 32. The electromagnetic valve 322 on the second flow path 32 can adjust the flow to the second flow path 32 according to demand, and the second flow meter 321 provides accurate flow data. The two work together to achieve accurate control of the normal temperature water flow.

[0042] The warm water flow path 4 is provided with a third temperature detection element for directly detecting the water temperature of the warm water in the warm water flow path 4 , which can improve the accuracy of the third temperature detection element in detecting the water temperature of the warm water in the warm water flow path 4 .

[0043] According to some embodiments of the present invention, referring to Figure 1 The water outlet flow path 3 also includes a third flow path 33, which is connected to the second flow path 32, and the third flow path 33 is connected to the normal temperature water inlet end of the faucet 9, which enriches the diversity of water temperature selection and allows users to directly obtain unheated purified normal temperature water, satisfying users' different preferences for water temperature in different seasons.

[0044] For example, the third flow path 33 is provided with a second one-way valve 331, which is used to control the opening or closing of the third flow path 33. A water outlet valve 332 is also provided downstream of the second one-way valve 331, which mainly controls the outflow of pure water after the entire purification process. The water outlet valve 332 has a flow regulation function, allowing the user to adjust the outflow speed of pure water according to needs, which can not only meet daily water needs but also save water resources.

[0045] The second flowmeter 321 is located between the solenoid valve 322 and the purification module 1, the water inlet end of the third flow path 33 is located between the second flowmeter 321 and the solenoid valve 322, the second flowmeter 321 is located upstream of the solenoid valve 322, and the second flowmeter 321 can not only obtain the flow rate of normal temperature water in the second flow path 32, but also obtain the flow rate of normal temperature water in the third flow path 33.

[0046] According to some embodiments of the present invention, referring to Figure 1 , the water outlet flow path 3 further includes a fourth flow path 34, the fourth flow path 34 is connected to the third flow path 33, and the fourth flow path 34 is connected to an external drinking water device. For example, the external drinking water device can be a pipeline machine, and the external drinking water device can be placed on a dining table or a wall in a living room. The water purified by the purification module 1 can be introduced into the external drinking water device through the fourth flow path 34. The external drinking water device can also heat the water. The user can obtain water through the external drinking water device, which can save the user the time of going to the drinking water device 100 to get water, and provide convenience for the user.

[0047] The fourth flow path 34 is provided with a switch 341, which can control the opening or closing of the fourth flow path 34. When the external drinking water device is not used for a long time, the fourth flow path 34 can be closed.

[0048] According to some embodiments of the present invention, referring to Figure 1 The purification module 1 includes a first filter element 11 and a second filter element 12. The first filter element 11 includes a first sub-filter element 111 and a second sub-filter element 112. The purification module 1 adopts a multi-stage filtration design, which can remove impurities of different types and sizes in the water layer by layer, including but not limited to suspended matter, bacteria, viruses, organic matter, inorganic salts, etc., thereby providing a deeper purification effect. Integrating the first sub-filter element 111 and the second sub-filter element 112 into one unit not only saves space, but also simplifies the maintenance and replacement process. For example, the first sub-filter element 111 can be a polypropylene filter membrane, the second sub-filter element 112 can be an activated carbon filter membrane, and the second filter element 12 can be a reverse osmosis membrane.

[0049] The first sub-filter element 111 has a first filter flow path 1111, the second sub-filter element 112 has a second filter flow path 1121, the second filter element 12 has a third filter flow path 121, and the third filter flow path 121 is connected between the first filter flow path 1111 and the second filter flow path 1121. The first sub-filter element 111 and the second sub-filter element 112 each have an independent filter flow path, and filter materials of different materials or technologies can be used to remove specific types of pollutants in a targeted manner.

[0050] The first sub-filter element 111 can be a pre-filter layer, which is used to remove large particles of impurities in the water, such as sand, rust, suspended matter, etc., to protect the subsequent precision filter layer from being blocked by large particles, and to extend the service life of the entire filtration system. The second filter element 12 is used to remove almost all impurities such as dissolved solids, organic matter, bacteria, viruses, etc. in the water, and produce high-quality drinking water close to pure water. The main function of the second sub-filter element 112 is to remove organic compounds, residual chlorine, odor, color and organic matter in the water.

[0051] For example, a wastewater flow path 6 is connected to one end of the second filter element 12. After the water is filtered by the second filter element 12, most of the dissolved solids and impurities are blocked to obtain pure water. In order to balance the pressure difference on both sides of the second filter element 12, a part of the water flow needs to be discharged as "rinsing water" or "concentrated water", which becomes wastewater. The generated wastewater is discharged through the wastewater flow path 6. A wastewater valve 61 is provided on the wastewater flow path 6, and the wastewater valve 61 is used to connect or close the wastewater flow path 6.

[0052] According to some embodiments of the present invention, referring to Figure 1 The purification module 1 also includes a booster pump 14, which is located between the first sub-filter element 111 and the second filter element 12. After the normal temperature water is initially processed by the first sub-filter element 111, the pressure will be increased by the booster pump 14, and then enter the second filter element 12 for deeper purification. By setting up the booster pump 14, it helps to overcome the problem of water flow slowing down caused by the resistance of the filter material, ensuring that a good water flow rate can be maintained even in the case of high-density filter materials.

[0053] The second temperature detection element 13 is located between the first sub-filter element 111 and the booster pump 14. The second temperature detection element 13 is used to detect the temperature of the water in the purification module 1. The water temperature may affect the filtering effect and equipment performance. Placing the second temperature detection element 13 before the booster pump 14 can ensure that the original state of the water before the booster treatment is monitored, which is particularly important for maintaining system efficiency and protecting subsequent filter components. For example, some filter materials may be sensitive to water temperature, and too high water temperature may affect their filtering performance or life.

[0054] For example, a second solid detection element is further provided between the first sub-filter element 111 and the booster pump 14 , and the second solid detection element is used to detect the value of solid particles after being filtered by the first sub-filter element 111 .

[0055] According to some embodiments of the present invention, referring to Figure 1 A first solid detection element 35 is provided on the water outlet flow path 3 for obtaining the solid particle value on the water outlet flow path 3. When the solid particle value is greater than a preset value, the control system can light up a prompt light on the purification module 1 to remind the user to replace the purification module 1.

[0056] A reflux flow path 7 is provided at the downstream of the first solid detection element 35 of the water outlet flow path 3. One end of the reflux flow path 7 is connected to the water outlet flow path 3, and the other end is connected between the booster pump 14 and the first filter element 11. The reflux flow path 7 is used for flushing the purification module 1 through the reflux flow path 7 after the purification module 1 is not used for a long time and is used again, so as to improve the safety of the purification module 1. A reflux valve 71 and a second one-way valve 72 are provided on the reflux flow path 7. The reflux valve 71 is used to control the return water flow rate, and the second one-way valve 72 is used to control the water flow in one direction and prevent the water from flowing in the opposite direction.

[0057] According to some embodiments of the present invention, referring to Figure 1 The water dispenser also includes an exhaust flow path 73, which is connected between the hot water tank 8 and the exhaust port of the faucet 9. When normal temperature water is filled into the hot water tank 8, the air in the hot water tank 8 can flow to the exhaust port of the faucet 9 through the exhaust flow path 73; when the hot water tank 8 flows water into the hot water flow path 5, the air can flow from the exhaust port of the faucet 9 into the hot water tank 8 through the exhaust flow path 73.

[0058] According to some embodiments of the present invention, the drinking water device 100 is a water purifier, a drinking water purifier, or a water-using device with a heating function or a cooling function.

[0059] The water purifier can be a household water purifier or a commercial water purifier. The water purifier has filtering and heating functions and can provide users with filtered room temperature water or warm water mixed with hot water and room temperature water.

[0060] A water purifier is a multifunctional drinking water device that integrates water purification and drinking functions. It can not only purify water, but also heat or cool room temperature water, providing a variety of options such as cold water, room temperature water or warm water. It is suitable for use in homes, offices and business places.

[0061] The water-using device with heating or cooling function can be a water heater. As users have an increasing demand for water used for bathing, a purification module 1 is added to the water heater to purify tap water. According to the temperature control method of the drinking water device 100 in the second embodiment of the utility model, the drinking water device 100 is the drinking water device 100 in the first embodiment of the utility model. First, the target water temperature of the drinking water device 100 is obtained, and then the normal temperature water inlet temperature and the hot water inlet temperature of the drinking water device 100 are obtained. According to the target water temperature, the normal temperature water inlet temperature and the hot water inlet temperature, the water inlet parameters of the drinking water device 100 are adjusted to make the drinking water device 100 output water at a constant temperature.

[0062] Specifically, in this embodiment of the utility model, after the drinking water device 100 stably discharges water, the target water temperature set by the user is obtained through the control panel of the drinking water device 100 by communication or cloud, and the normal temperature water inlet temperature and the hot water inlet temperature are also obtained through the temperature detection component, and the numerical values ​​obtained above are used for calculation to adjust the water inlet parameters of the drinking water device 100, and the water inlet parameters of the drinking water device 100 are obtained through the flow meter.

[0063] According to the temperature control method of the drinking water device 100 of the embodiment of the utility model, the purpose of precise temperature control is achieved by adjusting the water inlet parameters of the drinking water device 100, thereby ensuring that the water dispenser outputs water at a constant temperature.

[0064] According to some embodiments of the present invention, referring to Figure 1 The water inlet parameters include the normal temperature water inlet flow rate and the hot water inlet flow rate. The normal temperature water inlet flow rate is L1, the normal temperature water inlet temperature is T1, the hot water inlet flow rate is L2, the hot water inlet temperature is T2, and the constant temperature water outlet temperature of the drinking water equipment 100 is T, satisfying: T = (T1*L1+T2*L2) / (L1+L2).

[0065] For example, the normal temperature water inlet flow rate L1 and the hot water inlet flow rate L2 are less than 1.5 L / min. Under a fixed condition, the normal temperature water inlet temperature T1 and the hot water inlet temperature T2 are not adjustable. The normal temperature water inlet temperature T1 can be 25°C, and the hot water inlet temperature T2 can be 60°C. The target water temperature of the required drinking water device 100 is 45°C. The normal temperature water inlet flow rate L1 can be 1.0 L / min, and the hot water inlet flow rate L2 can be 1.35 L / min. The above formula is used to calculate:

[0066] (25℃*1.0L / min+60℃*1.35L / min) / (1.0L / min+1.35L / min)=45.1℃.

[0067] For another example, the normal temperature water inlet temperature T1 may be 25°C, the hot water inlet temperature T2 may be 70°C, the required target water temperature of the drinking water device 100 is 50°C, the normal temperature water inlet flow rate L1 may be 1.2L / min, and the hot water inlet flow rate L2 may be 1.5L / min, calculated by the above formula:

[0068] (25℃*1.2L / min+70℃*1.5L / min) / (1.2L / min+1.5L / min)=50℃.
