[0024] Figure 1 The figure is a schematic diagram of a water circuit of a water heater according to an embodiment of the utility model. Figure 2 for Figure 1 Schematic diagram of the electrical structure of the medium-sized hot water device. Figure 1 and 2 As shown, an embodiment of the utility model relates to a hot water device 10, which includes: a first water circuit 12, suitable for outputting first water, and an extraction device 14 for extracting the first water is arranged on the first water circuit 12, and the first water is hot water; a second water circuit 16, suitable for outputting second water, and the second water is a mixture of the first water and the third water, and the second water is warm water; a first temperature sensor 18, suitable for measuring the actual temperature of the second water; a receiver 20, suitable for receiving a target temperature of the target water input by a user; and a controller 22, suitable for judging whether to adjust the flow of the extraction device 14 according to the comparison result of the actual temperature of the second water and the target temperature.

[0025] In this way, the water heater 10 can provide hot water with accurate and adjustable temperature.

[0026] The water heater 10 may be any device suitable for outputting hot water and may have any possible structure as long as it is suitable for the present invention.

[0027] The extraction device 14 can be any device suitable for extracting the first water, and can have any possible structure, as long as it is suitable for the novel invention. For example, the extraction device 14 can be a high temperature resistant, flow-adjustable pump.

[0028] The first temperature sensor 18, the receiver 20 and the controller 22 may each have any applicable structure as long as they are applicable to the present invention. For example, the receiver 20 may be a display and / or operation module, such as a touch panel.

[0029] When the water heater 10 is working, the receiver 20 receives the target temperature of the target water input by the user and sends it to the controller 22. The controller 22 controls the first water path 12 to output the first water, or controls the second water path 16 to output the second water according to the target temperature of the target water. If the target water input by the user is warm water, the controller 22 can compare the actual temperature of the second water measured by the first temperature sensor 18 with the target temperature, and determine whether to adjust the flow rate of the extraction device 14 according to the comparison result, that is, determine whether to adjust the flow rate of the first water extracted by the extraction device 14, so that the actual temperature of the second water mixed by the first water and the third water is consistent with the target temperature, so that the temperature of the warm water provided by the water heater 10 is accurate.

[0030] When the receiver 20 receives the change in the target temperature of the warm water input by the user, the controller 22 re-compares the actual temperature of the second water measured by the first temperature sensor 18 with the changed target temperature, and determines whether to adjust the flow rate of the extraction device 14 based on the comparison result, that is, determines whether to adjust the flow rate of the first water extracted by the extraction device 14, so that the actual temperature of the second water mixed by the first water and the third water is consistent with the target temperature, so that the hot water device 10 can provide warm water with precise temperature.

[0031] Thus, the water heater 10 can provide warm water with precise and adjustable temperature.

[0032] In some embodiments, if the actual temperature of the second water is consistent with the target temperature, the controller 22 controls the flow rate of the extraction device 14 to remain unchanged.

[0033] When the actual temperature of the second water is consistent with the target temperature, there is no need to adjust the flow rate of the first water to adjust the actual temperature of the second water mixed by the first water and the third water, that is, the flow rate of the first water extracted by the extraction device 14 does not need to be changed, so the controller 22 controls the flow rate of the extraction device 14 to remain unchanged. Then, the extraction device 14 still extracts the first water at the current flow rate into the second waterway 16 to mix with the third water entering the second waterway into the second waterway and directly output it.

[0034] In some embodiments, the hot water device 10 also includes: a second temperature sensor 24, suitable for measuring the temperature of the third water entering the second water circuit 16, and sending the measured temperature of the third water to the controller 22; and a third temperature sensor 34, suitable for measuring the temperature of the first water, and sending the measured temperature of the first water to the controller 22. The second water circuit 16 also includes: a flow sensor 26, suitable for measuring the flow of the third water entering the second water circuit 16, and sending the measured flow of the third water to the controller 22. If the actual temperature of the second water is inconsistent with the target temperature, the controller 22 obtains the flow of the extraction device 14 based on the temperature of the third water, the flow of the third water, the target temperature, and the temperature of the first water.

[0035] The second temperature sensor 24 , the third temperature sensor 34 , and the flow sensor 26 may each have any possible configuration as long as it is suitable for the present invention.

[0036] The controller 22 receives the measurement results of the second temperature sensor 24, the flow sensor 26 and the third temperature sensor 34, thereby knowing the temperature and flow rate of the third water entering the second waterway 16 and the temperature of the first water, and when it is determined that the actual temperature of the second water is inconsistent with the target temperature and it is determined that the flow rate of the extraction device 14 needs to be adjusted, the flow rate of the extraction device 14 is obtained according to the temperature and flow rate of the third water entering the second waterway 16 and the temperature of the first water measured by the second temperature sensor 24, the flow sensor 26 and the third temperature sensor 34, and the target temperature. Thus, the flow rate of the first water entering the second waterway 16 is adjusted so that the actual temperature of the second water mixed by the first water and the third water is consistent with the target temperature.

[0037] In some embodiments, the controller 22 obtains the flow of the extraction device 14 according to the temperature of the third water, the flow of the third water, the target temperature, and the actual temperature of the second water according to the following formula (1): f1=(f2t2-f3t3) / t1(1), wherein f1 is the flow of the extraction device 14; t1 is the temperature of the first water; f2 is the flow of the second water, f2=f1+f3; t2 is the target temperature; f3 is the flow of the third water entering the second waterway 16; and t3 is the temperature of the third water entering the second waterway 16.

[0038] The controller 22 receives the measurement results of the second temperature sensor 24, the flow sensor 26 and the third temperature sensor 34 and obtains the temperature t3 and flow f3 of the third water entering the second water path 16, the temperature t1 of the first water, and combines the target temperature t2 to calculate the flow f1 of the extraction device 14 by formula (1). The controller 22 controls the extraction device 14 to extract the first water into the second water path 16 at the flow f1 of the extraction device 14 calculated according to formula (1) to mix with the third water entering the second water path 16, so as to obtain warm water with a temperature of the target temperature t2.

[0039] Reference Figure 1 In some embodiments, the second water channel 16 further includes: a mixing component 28, adapted to receive and mix the first water and the third water.

[0040] The mixing component 28 can be any component suitable for receiving and mixing the first water and the third water, as long as it is suitable for the present invention. For example, the mixing component 28 can be a tee.

[0041] The extraction device 14 extracts the first water output from the first water channel 12 and delivers it to the mixing component 28 of the second water channel 16. The third water entering the second water channel 16 reaches the mixing component 28 through the flow sensor 26. After reaching the mixing component 28, the first water and the third water are mixed into the second water and output from the second water channel 16 through the first temperature sensor 18.

[0042] In some embodiments, the second water path 16 further includes a flow restrictor 30 adapted to limit the flow rate of the third water entering the second water path 16 to match the rated flow rate of the extraction device 14 .

[0043] The flow restrictor 30 may have any suitable structure as long as it is suitable for the present invention.

[0044] The flow limiter 30 can limit the flow of the third water entering the second waterway 16 to a constant value that matches the rated flow of the extraction device 14, so as to accurately control the temperature of the second water output from the second waterway 16, which can be beneficial to stabilizing the flow of the second water output from the second waterway 16 and help prevent the water delivery function of the second waterway 16 from failing.

[0045] Figure 3 for Figure 1 In some embodiments, referring to Figure 1 and 3 The first water path 12 includes: a heater 32, which is suitable for heating water therein, and a third temperature sensor 34 is also suitable for measuring the temperature of the water in the heater 32 and sending the measured result to the controller 22.

[0046] The heater 32 can have any possible structure, as long as it is suitable for the present invention. For example, the heater 32 can be a water tank with a heating function.

[0047] The third temperature sensor 34 can measure the temperature of the water in the heater 32 and send the measured result to the controller 22, and the controller 22 controls the heater 32 to heat the water therein until the preset first water temperature is reached.

[0048] The extraction device 14 can extract the first water reaching the set temperature from the heater 32 and discharge it, thereby achieving the first water output through the first water path.

[0049] Reference Figure 1-3 In some embodiments, the first water circuit 12 further includes: a water level monitoring device 36, adapted to monitor water level changes in the heater 32 and send the measured results to the controller 22; and a first switch 38, adapted to control the third water to enter the heater 32 according to instructions of the controller 22.

[0050] The water level monitoring device 36 and the first switch 38 may each have any possible configuration as long as they are suitable for the present invention. For example, the first switch 38 may be a solenoid valve.

[0051] When the water level monitoring device 36 detects that the water level in the heater 32 drops, the result can be sent to the controller 22, and the controller 22 controls the first switch 38 to open, so that the third water enters the heater 32. After the third water enters the heater 32, the third temperature sensor 34 can send the temperature of the water in the heater 32 to the controller 22. If the temperature of the water in the heater 32 is lower than the set temperature at this time, the controller 22 controls the heater 32 to heat the water therein to the set temperature.

[0052] When the receiver 20 receives the target water input by the user as hot water, the controller 22 can control the extraction device 14 to extract the first water heated to the set temperature in the heater 32 and directly output it to the outside of the first water channel 14 after receiving the signal from the receiver 20 .

[0053] In some embodiments, the volume of the heater 32 is 1.5 liters to 5 liters, and the rated flow rate of the extraction device 14 is 1 liter / minute to 5 liters / minute.

[0054] This can help the water heater 10 to have a strong water production capacity and wide adaptability.

[0055] In the embodiment of the present application, the flow rate of the first water output by the first water channel 12 can be above 1.8 liters / minute, the flow rate of the second water output by the second water channel 16 can be above 3 liters / minute, and the allowable flow rate of the third water is 1 liter / minute to 7 liters / minute, with wide adaptability.

[0056] Reference Figure 1and 2 In some embodiments, the second water circuit 16 further includes: a second switch 40, adapted to control the third water to enter the second water circuit 16, and the controller 22 is further configured to control the opening and closing of the second switch 40 according to the target temperature of the target water input by the user.

[0057] The second switch 40 may have any possible structure as long as it is applicable to the present invention. For example, the second switch 40 may be a solenoid valve.

[0058] When the receiver 20 receives the user input that the target water is warm water, the controller 22 can control the extraction device 14 to extract the first water heated to the set temperature in the heater 32 and deliver it to the mixing component 28 of the second water path 16 after receiving the signal from the receiver 20. In addition, when the receiver 20 receives the user input that the target water is warm water, the controller 22 also controls the second switch 40 to open, so that the third water enters the second water path 16, passes through the flow sensor 26 and the flow limiter 30, reaches the mixing component 28, mixes with the first water therein to form the second water and outputs it.

[0059] Reference Figure 1 and 2 In some embodiments, the hot water device 10 also includes: a third water circuit 42, suitable for outputting third water, the third water circuit 42 also includes: a third switch 44, suitable for controlling the third water to enter the third water circuit 42, and the controller 22 is also configured to control the opening and closing of the third switch 44 according to the target temperature of the target water input by the user.

[0060] The third switch 44 may have any possible structure as long as it is applicable to the present invention. For example, the third switch 44 may be a solenoid valve.

[0061] When the receiver 20 receives the target water input by the user as room temperature water, the controller 22 can control the third switch 44 to open after receiving the signal from the receiver 20, so that the third water enters the second water path 42 and flows out directly.

[0062] In some embodiments, the temperature of the first water is any temperature between 60°C and 100°C.

[0063] In some embodiments, the temperature of the third water is any temperature between 5°C and 38°C.

[0064] When using the hot water device 10, the user only needs to input the target water and / or target temperature into the receiver 20, and the receiver 20 will send the information input by the user to the controller 22, and the controller 22 will judge and control the first water channel 12, the second water channel 16, and the third water channel 42 according to the target temperature of the target water input by the user, and automatically output the target water and / or water at the target temperature input by the user as described above.
