Description

Technical Field

[0001] The present disclosure relates to the technical field of drinking water equipment, and in particular to a drinking water equipment and a control method thereof. Background Art

[0002] The all-in-one water purifier and heat machine, also known as the all-in-one RO (Reverse Osmosis) machine, refers to a new type of water purifier that integrates water purification and heating functions. It eliminates the steps of collecting purified water and then boiling water. Pure hot water can be drunk immediately after it is opened, making drinking hot water safer, healthier and more convenient. It is a water purifier that integrates an electric kettle, a water dispenser and a water purifier. It can set the water outlet temperature or the insulation temperature according to user needs, so that the user can drink at the desired temperature in real time.

[0003] At present, there are two main heating methods for all-in-one water heaters: instant heating and hot tank heating. Since instant heating can adjust the water outlet temperature at any time, the experience effect and application range of instant heating are wider. However, there are also some shortcomings in the use of instant heating, mainly because the hot water flow rate is relatively small. According to the power of 2200W of general household electrical appliances, the water flow rate is only 430ml / min when setting 95℃ hot water. The waiting time for water is relatively long. It takes 50 seconds to receive a cup of 300ml water. The power of hot tank heating is the same as that of instant heating, but due to the existence of the storage tank, hot water can be stored in advance, and hot water can be discharged quickly and at a large flow rate when used. However, hot tank heating also has shortcomings in use. It can only produce hot water at one temperature, which cannot meet the needs of hot water at multiple temperatures, and the water output capacity of hot water is limited, which will be limited by the volume of the storage tank.

[0031] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0032] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products, or devices.

[0033] The drinking water equipment provided by the embodiment of the present disclosure includes a first water tank, a second water tank, a first booster pump, and a second booster pump, wherein a heating device is provided in the second water tank for heating the water in the second water tank to a certain temperature; the first booster pump is provided at the water outlet of the first water tank, the second booster pump is provided at the water outlet of the second water tank, and the water outlets of the first booster pump and the second booster pump are both connected to the water outlet. In a specific implementation, the heating device in the second water tank is used to heat the water in the second water tank, and when the water temperature in the second water tank reaches a certain temperature, the heating device is controlled to stop working. Among them, the above-mentioned certain temperature can be set according to actual needs, for example, it can be set to 95°C. Due to the heat diffusion of the heating water tank, once it is not heated, the water in the second water tank will gradually and slowly cool down, so it is necessary to set a temperature compensation point, for example, 93°C. Once the water temperature in the second water tank drops below the temperature compensation point, the heating device is controlled to work again until the water temperature in the second water tank reaches the set temperature.

[0034] The drinking water equipment provided in the embodiment of the present disclosure includes two water tanks and two corresponding booster pumps, wherein the booster pump is used to increase the water pressure to ensure that the water can be smoothly pumped out of the water tank. Specifically, the booster pump drives the impeller to rotate through the motor to generate centrifugal force, so that the water in the water tank is sucked into the pump body and obtains additional pressure, thereby pushing the water through the pipeline to the rear end. Therefore, the flow rate of water reaching the rear end can be adjusted by adjusting the voltage of the motor in the booster pump. It should be noted that the adjustment of the voltage of the booster pump involved in the embodiment of the present disclosure specifically refers to adjusting the voltage of the motor in the booster pump.

[0035] In the control method of the drinking water equipment provided in the embodiment of the present disclosure, according to the correspondence between the voltage of the first booster pump and the second booster pump and the calibrated flow ratio, the voltage of the first booster pump and the second booster pump is adjusted with reference to the calibrated flow ratio, so that the actual flow ratio of the two booster pumps can be controlled, so that the outlet water temperature after mixing the first water tank and the second water tank can quickly reach the set temperature, improving the user's experience of using the drinking water equipment. Compared with instant hot water drinking equipment, users can quickly obtain water with a large flow rate and set temperature through the drinking water equipment provided by the present disclosure; compared with hot tank hot water drinking equipment, users can obtain water with different set temperatures through the drinking water equipment provided by the embodiment of the present disclosure.

[0036] The drinking water device in the embodiment of the present disclosure may be a drinking water device with a heating function, and may also have other functions, such as a water purification function, on the basis of the heating function. In practical applications, the drinking water device may be a water purification and heating integrated machine.

[0037] Figure 1 A schematic diagram for illustrating a heat and air conditioning machine. Figure 1In the example shown, the heat and water heater comprises a processor ( Figure 1 The invention also includes a water pump 20, a first booster pump 21, a second booster pump 22 and a return water pump 23, a composite filter element 31, a membrane chromatographic filter element 32, a first water tank 33, a second water tank 34, a heating device 35 and a water mixing chamber 36, wherein the composite filter element 31 includes a pre-filter element and a post-filter element. The water in the waterway is activated by the water inlet valve 10 and the water pump 20, and the water in the waterway passes through the water inlet end and is filtered in turn by the pre-filter element, the membrane chromatographic filter element 32 and the post-filter element to form purified water. The processor can discharge the wastewater produced by purification by activating the wastewater valve 11, and can replenish water to the first water tank 33 and the second water tank 34 by activating the hot water valve 14 and the water tank valve 15. The first water level sensor 331 provided in the first water tank 33 can detect whether the water in the first water tank 33 is in place, and the second water level sensor 341 provided in the second water tank 34 can detect whether the water in the second water tank 34 is in place. After the water replenishment is completed, the processor is used to control the heating device 35 provided in the second water tank 34 to heat the water in the second water tank 34. The water in the first water tank 33 is usually room temperature water. In order to avoid the growth of bacteria, a sterilizer 332, such as an ultraviolet lamp, can also be provided in the first water tank 33. In addition, in order to further prevent the water in the first water tank from growing bacteria, the processor can start by controlling the drain valve 12 so that the water in the first water tank 33 is filtered again through the membrane chromatography filter element 32 and the post-filter element, so as to be reused.

[0038] like Figure 1 As shown, the air conditioner and heat unit further includes a first temperature sensor 41, a second temperature sensor 42 and a third temperature sensor 43. The first temperature sensor 41 is used to measure the water temperature of the first water tank 33, the second temperature sensor 42 is used to measure the water temperature of the second water tank 34, and the third temperature sensor 43 is used to measure the outlet water temperature of the water outlet.

[0039] The water flowing out of the first water tank 33 and the second water tank 34 is mixed in the water mixing chamber 36 and reaches the water outlet. The processor can adjust the voltage of the first booster pump 21 and the second booster pump 22 to make the water of different temperatures flow out of the water outlet. After the water outlet stops discharging water, the processor can also control the return pump 23 to run so that the residual water in the water outlet pipeline is discharged. When the user needs to drink water at room temperature, the first booster pump 21 can be controlled to run and the second booster pump 22 can be stopped to provide the user with water in the first water tank 33. When the water in the first water tank 33 is emptied, the processor can start the water outlet valve 13 to make a small flow of normal temperature water flow directly out of the water outlet.

[0040] Example 1

[0041] Figure 2 This is a flow chart of a control method for a drinking water device provided in this embodiment. The control method for the drinking water device can be executed by a control device for the drinking water device. The control device for the drinking water device can be implemented by software and / or hardware. The control device for the drinking water device can be part or all of the drinking water device. The control method for the drinking water device provided in this embodiment is introduced below with the drinking water device as the execution subject.

[0042] like Figure 2 As shown, the control method of the drinking water equipment provided in this embodiment may include the following steps S101 to S103:

[0043] Step S101: In response to a drinking water demand, the actual flow ratio between the first booster pump and the second booster pump is controlled according to the temperature difference between a set temperature and an actual water outlet temperature, so that the actual water outlet temperature reaches the set temperature.

[0044] In actual applications, the demand for drinking water is usually triggered by the user. For example, the user can trigger the demand for drinking water by pressing a button on the drinking water device, or by voice or other means. The drinking water demand carries information about the set temperature. In a specific example, the drinking water device includes four buttons corresponding to room temperature, 45°C, 75°C, and 100°C, respectively. The user can trigger the drinking water demand with a set temperature of 45°C by pressing the button corresponding to 45°C.

[0045] In a specific implementation, the algorithm for controlling the actual flow ratio may be a PID algorithm or a fuzzy control algorithm, and the specific algorithm is not limited. In the example of performing PID control on the actual flow ratio, the actual flow ratio P(t) at time t can be determined according to the following formula:

[0046] P(t)=Kp1×e(t)+Ki1×Σe(t)+Kd1×(e(t)-e(t-1));

[0047] Among them, e(t) is the temperature difference at time t, specifically, e(t) = Tset-Tout_real; Tset is the set temperature, Tout_real is the actual water outlet temperature at the water outlet of the drinking water equipment at time t, e(t-1) is the temperature difference at time t-1, Kp1, Ki1 and Kd1 are the proportional coefficient, integral coefficient and differential coefficient of PID control respectively.

[0048] Step S102: searching for a calibrated flow ratio corresponding to the actual flow ratio from at least two calibrated flow ratios corresponding to different outlet water temperatures.

[0049] Among them, the calibrated flow ratio is determined in advance. Specifically, the corresponding calibrated flow ratio is determined for different water outlet temperatures of the drinking water equipment. In the specific implementation of step S102, in order to improve the accuracy of the water outlet temperature, the calibrated flow ratio that is the same as the actual flow ratio can be preferentially searched among the multiple calibrated flow ratios determined in advance. If there is no calibrated flow ratio that is the same as the actual flow ratio, the calibrated flow ratio that is closest to the actual flow ratio can be searched. If there are two calibrated flow ratios that are the same as the actual flow ratio, any one of them can be selected.

[0050] In a specific example, the pre-determined calibrated flow ratios corresponding to different water outlet temperatures include 1.135, 1.45, 1.166, 1.172, 1.191, 1.213, 1.244, 1.258, ...; the actual flow ratio determined at time t is 1.233, then the calibrated flow ratio closest to 1.233 is 1.244 from the above multiple calibrated flow ratios.

[0051] Step S103, adjusting the current voltage of the first boost pump according to the first calibration voltage, and adjusting the current voltage of the second boost pump according to the second calibration voltage. The first calibration voltage is the voltage of the first boost pump corresponding to the calibration flow ratio, and the second calibration voltage is the voltage of the second boost pump corresponding to the calibration flow ratio.

[0052] After determining the calibrated flow ratio corresponding to the actual flow ratio, the current voltage of the first booster pump is adjusted according to the voltage of the first booster pump corresponding to the calibrated flow ratio, and the current voltage of the second booster pump is adjusted according to the voltage of the second booster pump corresponding to the calibrated flow ratio. After adjusting the current voltages of the first booster pump and the second booster pump, the amount of water flowing out of the first water tank and the second water tank will also change accordingly, and after mixing, it reaches the water outlet. At this time, the actual water outlet temperature will also change accordingly. According to the temperature difference between the set temperature and the actual water outlet temperature and the corresponding control algorithm, a new actual flow ratio can be obtained, and then a new calibrated flow ratio corresponding to the new actual flow ratio is searched from multiple calibrated flow ratios. Finally, the current voltages of the two booster pumps are adjusted according to the voltages of the two booster pumps corresponding to the new calibrated flow ratio. This cycle is repeated until the actual water outlet temperature of the drinking water equipment reaches the set temperature.

[0053] In an optional embodiment, Figure 3 As shown, the corresponding relationship between the calibrated flow ratio and the voltage of the first boost pump and the voltage of the second boost pump is determined according to the following steps 201 to 203:

[0054] Step 201: Record the outlet water temperatures of the first booster pump and the second booster pump at different voltages.

[0055] In a specific implementation, the voltage of the first boost pump, the voltage of the second boost pump, and the corresponding water outlet temperature are recorded respectively. In a specific example, the voltage of the second boost pump is adjusted to the maximum, and then the voltage of the first boost pump is gradually increased from 0V until the voltage of the first boost pump is adjusted to the maximum, wherein each time the voltage of the first boost pump is adjusted, the corresponding water outlet temperature is recorded once, so that the water outlet temperature of the second boost pump at the maximum voltage and the first boost pump at different voltages is obtained. After that, the voltage of the second boost pump is gradually reduced until the voltage of the second boost pump is adjusted to 0V, wherein each time the voltage of the second boost pump is adjusted, the corresponding water outlet temperature is recorded once, so that the water outlet temperature of the first boost pump at the maximum voltage and the second boost pump at different voltages is obtained. Combining the above two situations, the water outlet temperatures of the first boost pump and the second boost pump at different voltages can be obtained.

[0056] It should be noted that the voltage of the first boost pump adjusted each time can be set according to the maximum voltage U1 of the first boost pump, for example, 1 / 10 U1 is adjusted each time. The voltage of the second boost pump adjusted each time can be set according to the maximum voltage U2 of the second boost pump, for example, 1 / 10 U2 is adjusted each time. In practical applications, the voltage adjusted each time can also be fixed, for example, 2V is increased or 2V is decreased each time, etc.

[0057] Step 202: for different outlet water temperatures, calculate a calibration flow ratio according to the water temperature of the first water tank, the water temperature of the second water tank and the outlet water temperature.

[0058] In a specific implementation, the calibration flow ratio Kflow can be calculated according to the following formula:

[0059] Kflow=(Ttop-Tout) / (Tout-Tlow);

[0060] Wherein, Tout is the outlet water temperature, Tlow is the water temperature of the first water tank, and Ttop is the water temperature of the second water tank. In a specific example, the water temperature Tlow of the first water tank is 30°C, the water temperature Ttop of the second water tank is 95°C, and the outlet water temperature Tout is 60°C. The corresponding calibrated flow ratio Kflow = (95-60) / (60-30) = 1.167.

[0061] Step 203: Determine the corresponding relationship between the calibrated flow ratio and the voltage of the first boost pump and the voltage of the second boost pump according to the corresponding relationship between the calibrated flow ratio and the outlet water temperature, and the corresponding relationship between the outlet water temperature and the voltage of the first boost pump and the second boost pump.

[0062] In a specific implementation, there is a corresponding relationship between the outlet water temperature and the calibrated flow ratio, and there is also a corresponding relationship between the outlet water temperature and the voltages of the two booster pumps. Based on these two corresponding relationships, the corresponding relationship between the calibrated flow ratio and the two booster pumps can be derived.

[0063] In an optional embodiment, the drinking water equipment further includes a return water pump, and the water inlet of the return water pump is connected to the water outlets of the first booster pump and the second booster pump, respectively. In this embodiment, the control method further includes: in response to the water outlet stopping the water outlet, controlling the return water pump to operate so that the water in the water outlet pipeline is discharged. In a specific implementation, the return water pump can be controlled to operate for a period of time T, and then the return water pump is controlled to stop operating. Among them, T can be set according to the actual situation of the water outlet pipeline.

[0064] In this embodiment, after the water outlet stops discharging water each time, the residual water in the water outlet pipe is discharged by controlling the operation of the return water pump, which not only avoids the problem of inaccurate water outlet temperature due to residual water, but also avoids the situation where the user is scalded by the residual water at a higher temperature.
