[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0029] Reference below Figure 1 The drinking water device 100 according to an embodiment of the present invention is described.

[0030] like Figure 1 As shown, the drinking water equipment 100 according to the embodiment of the utility model includes: a faucet 10, a water purification module 20, a first pipeline 30, a hot water tank 40, a second pipeline 50 and a third pipeline 60.

[0031] Specifically, the water inlet end of the water purification module 20 is connected to the external water circuit, the first pipeline 30 is connected between the water outlet end of the water purification module 20 and the faucet 10, the first pipeline 30 is connected in series with a first flow meter 31, and a first temperature sensor 21 is provided in the water purification module 20. The second pipeline 50 is connected between the water outlet end of the water purification module 20 and the water inlet end of the hot water tank 40, the third pipeline 60 is connected between the water outlet end of the hot water tank 40 and the faucet 10, the third pipeline 60 is connected in series with a second flow meter 61, and a second temperature sensor 41 is provided in the hot water tank 40.

[0032] Among them, the first flowmeter 31 can detect the flow on the first pipeline 30, that is, the water outlet flow of the water purification module 20, the first temperature sensor 21 can detect the water temperature in the water purification module 20, the second flowmeter 61 can detect the flow on the third pipeline 60, that is, the water outlet flow of the hot water tank 40, the second temperature sensor 41 can detect the water temperature in the hot water tank 40, the drinking water equipment 100 has a control module, the control module is electrically connected to the water purification module 20 and the hot water tank 40, the control module can receive the data collected by the first flowmeter 31, the first temperature sensor 21, the second flowmeter 61 and the second temperature sensor 41, and a heating device is provided in the hot water tank 40, and the heating device can heat the water in the hot water tank 40.

[0033] During the operation of the drinking water device 100, water from the external waterway enters the water purification module 20 from the water inlet end of the water inlet module, and the water purification module 20 purifies the water. The water purified by the water purification module 20 can flow directly to the faucet 10 from the first pipeline 30. The water purified by the water purification module 20 can also enter the hot water tank 40 from the second pipeline 50. The hot water tank 40 heats the water, and the heated water can flow into the faucet 10 from the third pipeline 60. In this way, during use, the user can connect the first pipeline 30 with the faucet 10 to release purified water at room temperature from the faucet 10, or connect the third pipeline 60 with the faucet 10 to release heated purified water from the faucet 10. It is also possible that both the first pipeline 30 and the third pipeline 60 are connected to the faucet 10, the purified water at room temperature is mixed with the heated purified water, and warm water with a temperature between room temperature and hot water temperature is released from the faucet 10.

[0034] During the operation of the drinking water device 100, the first temperature sensor 21 detects the water temperature in the water purification module 20, and sets the temperature of the normal temperature water in the water purification module 20 to T1. The first flow meter 31 detects the water flow in the first pipeline 30, and sets the flow of the normal temperature water in the first pipeline 30 to L1. The second temperature sensor 41 detects the water temperature in the hot water tank 40, and sets the water temperature in the hot water tank 40 to T2. The second flow meter 61 detects the water flow in the third pipeline 60, and sets the hot water flow in the third pipeline 60 to L2. For those skilled in the art, It can be understood that when the first pipeline 30 and the third pipeline 60 are both connected to the faucet 10, when the purified water at room temperature and the heated purified water are mixed in the faucet 10, the water outlet temperature T of the faucet 10 is (T1*L1+T2*L2) / (L1+L2). Therefore, when the user wants to release purified water of a specific temperature from the drinking water equipment 100, the control module can calculate the water outlet temperature of the faucet 10 by controlling the water flow in the first pipeline 30 and the third pipeline 60 according to the above calculation formula, and the control of the water outlet temperature of the faucet 10 is more precise.

[0035] According to the drinking water device 100 of the embodiment of the present invention, the water outlet temperature of the faucet 10 can be more accurately controlled, thereby improving the user experience.

[0036] In some embodiments of the present invention, Figure 1 As shown, the water purification module 20 includes: a first water pump 22, and the first water pump 22 is configured to have an adjustable water outlet flow rate. During the operation of the water purification module 20, the first water pump 22 drives water to flow in the water purification module 20. It can be understood that when the water outlet flow rate of the first water pump 22 changes, the water outlet flow rate of the water purification module 20 will also change. In this way, the water outlet end of the water purification module 20, the second pipeline 50 and the hot water tank 40 are in a closed state, and the water outlet end of the water purification module 20 and the first pipeline 30 are in an open state. By changing the water outlet flow rate of the first water pump 22, the flow rate of the normal temperature purified water in the first pipeline 30 can be changed, thereby realizing the regulation of the normal temperature purified water flow rate in the first pipeline 30, and the first water pump 22 is easy to arrange in the water purification module 20, which can reduce the difficulty of production and product design.

[0037] Among them, it is understandable to those skilled in the art that the water flow rate of the first water pump 22 can be regulated by adjusting parameters such as the voltage of the first water pump 22, the operating frequency of the first water pump 22, or the duty cycle of the first water pump 22.

[0038] In some embodiments of the present invention, Figure 1 As shown, a water outlet valve 32 is also connected in series to the first pipeline 30 . By setting the water outlet valve 32 , the water outlet valve 32 can open and close the first pipeline 30 , so that the drinking water equipment 100 can adjust the water supply state of the first pipeline 30 to the faucet 10 .

[0039] In some embodiments of the present invention, Figure 1 As shown, the water purification module 20 further includes: a first filter element 23 and a reverse osmosis membrane filter element 24, the first filter element 23 is arranged upstream of the waterway of the reverse osmosis membrane filter element 24, and the first water pump 22 is arranged between the first filter element 23 and the reverse osmosis membrane filter element 24. During the operation of the water purification module 20, the water flow entering the water purification module 20 from the water inlet end of the water purification module 20 first passes through the first filter element 23, the first filter element 23 filters the water flow, and then the first water pump 22 pressurizes the water flow filtered by the first filter element 23, and the pressurized water flow passes through the reverse osmosis membrane filter element 24, and the reverse osmosis membrane filter element 24 filters the water flow again.

[0040] Among them, the filtering size of the first filter element 23 is larger than the filtering size of the reverse osmosis membrane filter element 24. The first filter element 23 can filter out larger impurities in the water flow. The reverse osmosis membrane filter element 24 further filters the water flow and can improve the purification effect of the water purification device on the water flow. It can be understood by those skilled in the art that the reverse osmosis membrane filter element 24 has a large resistance to the water flow. By pressurizing the water flow entering the reverse osmosis membrane filter element 24 through the first water pump 22, the filtering efficiency of the reverse osmosis membrane filter element 24 on the water flow can be improved.

[0041] In some embodiments of the present invention, Figure 1 As shown, the water purification module 20 also includes: a second filter element 25, the second filter element 25 is arranged downstream of the water path of the reverse osmosis membrane filter element 24, and the first filter element 23 and the second filter element 25 are integrated into one. The water flow filtered by the reverse osmosis membrane filter element 24 flows out of the reverse osmosis membrane filter element 24 and passes through the second filter element 25, and the second filter element 25 filters the water flow again, thereby further improving the purification effect of the water purification device on the water flow. Among them, the first filter element 23 and the second filter element 25 are integrated into one, which can make the first filter element 23 and the second filter element 25 easier to arrange, thereby reducing the difficulty of design and assembly during the production process.

[0042] In some embodiments of the present invention, Figure 1 As shown, the water purification module 20 also includes: a first TDS detection element 26 and a second TDS detection element 27. The first TDS detection element 26 is arranged between the first filter element 23 and the reverse osmosis membrane filter element 24, and the second TDS detection element 27 is arranged between the second filter element 25 and the water outlet end of the water purification module 20.

[0043] Among them, the TDS value can reflect the effect of water purification. The first TDS detection element 26 can detect the TDS value of the water flow flowing out of the first filter element 23, and the first TDS detection element 26 can transmit the detection result to the control module. The second TDS detection element 27 can detect the TDS value of the water flow flowing out of the second filter element 25, and the second TDS detection element 27 can also transmit the detection result to the control module. In this way, the control module can make a judgment based on the detection results transmitted by the first TDS detection element 26 and the second TDS detection element 27. When the TDS value detected by the first TDS detection element 26 is abnormal, the filtering function of the first filter element 23 is abnormal. At this time, the drinking water equipment 100 can prompt the user to check whether the first filter element 23 needs to be processed. When the TDS value detected by the second TDS detection element 27 is abnormal, the filtering function of the reverse osmosis membrane filter element 24 and / or the second filter element 25 is abnormal. At this time, the drinking water equipment 100 can prompt the user to check whether the reverse osmosis membrane filter element 24 and the second filter element 25 need to be processed. In this way, the filtering function of the drinking water equipment 100 can be monitored, so that the user can know in time whether the filtering function of the drinking water equipment 100 is normal, thereby further improving the user's use experience.

[0044] In some embodiments of the present invention, Figure 1 As shown, the water purification module 20 also includes: a wastewater pipeline 28, which is connected to the reverse osmosis membrane filter element 24 and is used to discharge the wastewater generated by the reverse osmosis membrane filter element 24. The wastewater generated during the filtration process of the reverse osmosis membrane filter element 24 is discharged from the water purification module 20 through the wastewater pipeline 28, which can prevent the wastewater from accumulating in the water purification module 20. The wastewater pipeline 28 can provide a channel for the wastewater to be discharged to a designated place.

[0045] A wastewater valve 281 is serially connected to the wastewater pipeline 28 , and the wastewater valve 281 can open and close the wastewater pipeline 28 , thereby realizing the switching of the flow state of the wastewater pipeline 28 .

[0046] In some embodiments of the present invention, Figure 1 As shown, the drinking water equipment 100 also includes: a first one-way valve 33 and a return pipe 70, the first one-way valve 33 is connected in series to the first pipe 30, one end of the return pipe 70 is connected to the first pipe 30 between the first one-way valve 33 and the water purification module 20, the other end of the return pipe 70 is connected to the water purification module 20, and a reflux valve 71 is connected in series to the return pipe 70.

[0047] It is understandable that the faucet 10 is in direct contact with the external environment, and the faucet 10 is easily contaminated. When the water in the faucet 10 flows back to the water purification module 20 through the first pipeline 30, the pollutants at the faucet 10 may contaminate the water purification module 20, and even the impurities at the faucet 10 enter the water purification module 20 and affect the normal operation of the water purification module 20. By setting the first one-way valve 33, the first one-way valve 33 can prevent the water at the faucet 10 from flowing back to the water purification module 20 from the first pipeline 30.

[0048] When the water pressure in the first pipeline 30 is relatively high, the water pressure may react to the water outlet end of the water purification module 20 and may damage the water purification module 20. By setting the return water pipeline 70, when the water pressure in the first pipeline 30 is relatively high, the water pressure in the return water pipeline 70 is also relatively high. When the water pressure in the return water pipeline 70 is greater than the opening water pressure of the return valve 71, the return valve 71 opens the return water pipeline 70, and the water in the first pipeline 30 flows back to the water purification module 20 through the return water pipeline 70, thereby reducing the water pressure in the first pipeline 30. As a result, the probability of the water purification module 20 being damaged during the operation of the drinking water equipment 100 can be reduced, thereby improving the reliability of the drinking water equipment 100 during operation.

[0049] Among them, preferably, a second one-way valve 72 is connected in series between the return valve 71 and the water purification module 20, so that the water in the water purification module 20 can be prevented from directly entering the return valve 71, thereby preventing unpurified or unpurified water from entering the faucet 10 through the return pipe 70.

[0050] In some embodiments of the present invention, Figure 1 As shown, the drinking water device 100 further includes: a pipeline machine 81 and a fourth pipeline 80, and the fourth pipeline 80 is connected between the pipeline machine 81 and the water outlet of the water purification module 20. During the use of the user, the water purified by the water purification module 20 can flow into the pipeline machine 81 from the fourth pipeline 80, and the user can release the water purified by the water purification module 20 through the pipeline machine 81. During the product design process, the direction of the fourth pipeline 80 and the position of the pipeline machine 81 can be adjusted to meet more user needs.

[0051] The fourth pipeline 80 is serially connected with a pipeline switch 82 , and the pipeline switch 82 can open and close the fourth pipeline 80 , thereby adjusting the water supply state of the pipeline machine 81 .

[0052] In some embodiments of the present invention, Figure 1As shown, the water outlet of the hot water tank 40 is connected in series with a second water pump 42, and the second water pump 42 is configured to have an adjustable water outlet flow rate. During the operation of the drinking water device 100, the second water pump 42 drives the hot water flowing out of the hot water tank 40 to flow in the third pipeline 60. When the water outlet flow rate of the second water pump 42 changes, the hot water flow rate in the third pipeline 60 will also change. Thus, the hot water flow rate in the third pipeline 60 can be adjusted, and the second water pump 42 is easy to arrange, which can reduce the difficulty of production and product design.

[0053] Among them, it is understandable to those skilled in the art that the water flow rate of the second water pump 42 can be regulated by adjusting parameters such as the voltage of the second water pump 42, the operating frequency of the second water pump 42, or the duty cycle of the second water pump 42.

[0054] In some embodiments of the present invention, Figure 1 As shown, the drinking water device 100 further includes: an exhaust pipe 43, the exhaust pipe 43 is connected to the hot water tank 40, and the exhaust pipe 43 is suitable for connecting the hot water tank 40 with the external environment. It can be understood that when the heating device in the hot water tank 40 heats the water, the pressure in the hot water tank 40 will increase. By setting the exhaust pipe 43, when the pressure in the hot water tank 40 is greater than the set threshold, the exhaust pipe 43 is opened to discharge the high-pressure gas in the hot water tank 40, thereby reducing the pressure in the hot water tank 40 and improving the reliability of the drinking water device 100 during operation.

[0055] In some embodiments of the present invention, Figure 1 As shown, a water replenishment valve 51 is also connected in series to the second pipeline 50. During the operation of the drinking water device 100, when the water storage amount in the hot water tank 40 is small, the water replenishment valve 51 opens the second pipeline 50, and the water purified by the water purification module 20 flows from the second pipeline 50 into the hot water tank 40, thereby replenishing the water storage in the hot water tank 40. After the water storage in the hot water tank 40 is replenished, the water replenishment valve 51 closes the second pipeline 50.

[0056] In some embodiments of the present invention, Figure 1 As shown, the water inlet end of the water purification module 20 is connected to the external water circuit through the water inlet pipe 29, and a water inlet valve 291 is connected in series to the water inlet pipe 29. A filter is provided in the water inlet pipe 29, wherein the water inlet valve 291 can open and close the water inlet pipe 29, thereby realizing the change of the water inlet state of the water purification module 20, and the filter can perform preliminary filtering on the water flow entering the water purification module 20.

[0057] In 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.

[0058] 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.

[0059] The water purifier is a multifunctional drinking water device 100 that integrates water purification and drinking functions. It can not only purify water, but also heat or cool normal temperature water, providing a variety of options such as cold water, normal temperature water or warm water, and is suitable for use in homes, offices and business places.

[0060] The water-using device with a heating function or a cooling function may be a water heater. As users have an increasing demand for water used for bathing, a purification module is added to the water heater to purify tap water.
