Description

Technical Field

[0001] This invention relates to the field of water purification equipment technology, specifically providing a control method and water purification equipment for water purification. Background Technology

[0002] As people's living standards improve, their demand for drinking water is also increasing. Water purifiers, water dispensers, and other drinking water equipment are gradually becoming essential drinking water facilities in people's daily lives.

[0003] Taking water dispensers as an example, most existing water dispensers use instant heating elements to heat water to meet users' needs for hot drinking water. In order to improve heating efficiency and reduce users' waiting time, the hot water in the insulated tank is usually transferred to the instant heating element for heating.

[0004] However, when the water dispenser is used in summer, the water temperature inside the insulation tank is relatively high, resulting in higher hot water temperature and flow rate from the outlet. In winter, the water temperature inside the insulation tank is relatively low, resulting in lower hot water temperature and flow rate from the outlet. This leads to a significant difference between the water temperature and flow rate of the water dispenser, which seriously affects the user experience. Summary of the Invention

[0005] The present invention aims to solve the above-mentioned technical problems to at least a certain extent, that is, to solve the problem that the user experience of existing water purifiers is poor due to the large difference in water output data in different seasons.

[0006] In a first aspect, the present invention provides a control method for a water purification device, the water purification device comprising a water tank, a water pump, a heating component, a detection component, and a water outlet component. The heating component has a heating chamber, the water pump is used to pump water from the water tank into the heating chamber, the heating component is capable of heating the water in the heating chamber, the detection component is used to detect water outlet data at the water outlet end of the heating chamber, and the water outlet end of the heating chamber is selectively connected to the water outlet component or the water tank. The control method includes the following steps: acquiring water outlet data at the water outlet end of the heating chamber; acquiring target data corresponding to the water outlet data; and selectively connecting the water outlet end of the heating chamber to the water outlet component or the water tank based on the water outlet data and the target data; wherein the water outlet data is water temperature and / or water flow rate.

[0007] In the preferred embodiment of the control method for the above-mentioned drinking water purification equipment, the water output data is the water temperature and water flow rate. The step of "acquiring the water output data of the water outlet of the heating chamber" specifically includes: acquiring the water temperature and water flow rate of the water outlet of the heating chamber; the step of "acquiring target data corresponding to the water output data" specifically includes: acquiring the target water temperature corresponding to the water temperature and acquiring the target flow rate corresponding to the water flow rate; the step of "selectively connecting the water outlet of the heating chamber to the water outlet component or the water tank according to the water output data and the target data" specifically includes: selectively connecting the water outlet of the heating chamber to the water outlet component or the water tank according to the water temperature, the target water temperature, the water flow rate, and the target flow rate.

[0008] In the preferred technical solution of the control method for the above-mentioned drinking water purification equipment, the step of "selectively connecting the outlet end of the heating chamber to the outlet component or the water tank according to the outlet water temperature and the target water temperature, as well as the outlet flow rate and the target flow rate" specifically includes: calculating a first difference △1 = |T-T0|; calculating a second difference △2 = |Q-Q0|; comparing the first difference △1 with a first preset value A1; comparing the second difference △2 with a second preset value A2; and selectively connecting the outlet end of the heating chamber to the outlet component or the water tank according to the comparison result; wherein, T is the outlet water temperature of the outlet end of the heating chamber, T0 is the target water temperature corresponding to the outlet water temperature T, Q is the outlet flow rate of the outlet end of the heating chamber, Q0 is the target flow rate corresponding to the outlet flow rate Q, A1≥0, A2≥0.

[0009] In the preferred embodiment of the control method for the above-mentioned water purification equipment, the step of "selectively connecting the water outlet of the heating chamber to the water outlet component or the water tank according to the comparison result" specifically includes: if △1≤A1 and △2≤A2, then connecting the water outlet of the heating chamber to the water outlet component.

[0010] In the preferred embodiment of the control method for the above-mentioned water purification equipment, the step of "selectively connecting the water outlet of the heating chamber to the water outlet component or the water tank according to the comparison result" specifically includes: if △1>A1 and / or △2>A2, then connecting the water outlet of the heating chamber to the water tank.

[0011] In the preferred embodiment of the control method for the above-mentioned drinking water purification equipment, when the water outlet of the heating chamber is connected to the water tank, the control method further includes: selectively adjusting the water pump and / or the heating component according to the comparison result so that the water outlet temperature reaches the target water temperature and / or the water outlet flow rate reaches the target flow rate.

[0012] In the preferred embodiment of the control method for the above-mentioned water purification equipment, the step of "selectively adjusting the water pump and / or the heating component according to the comparison results to make the outlet water temperature reach the target water temperature and / or make the outlet water flow rate reach the target flow rate" specifically includes: if Δ1 > A1 and Δ2 > A2, then adjusting the water pump and the heating component to make the outlet water temperature reach the target water temperature and make the outlet water flow rate reach the target flow rate.

[0013] In the preferred embodiment of the control method for the above-mentioned drinking water purification equipment, the step of "selectively adjusting the water pump and / or the heating element according to the comparison results to make the outlet water temperature reach the target water temperature and / or make the outlet water flow rate reach the target flow rate" specifically includes: if Δ1>A1 and Δ2≤A2, then adjust the heating element to make the outlet water temperature reach the target water temperature, and do not adjust the water pump.

[0014] In the preferred embodiment of the control method for the above-mentioned water purification equipment, the step of "selectively adjusting the water pump and / or the heating element according to the comparison results to make the outlet water temperature reach the target water temperature and / or make the outlet water flow rate reach the target flow rate" specifically includes: if Δ1≤A1 and Δ2>A2, then first adjust the water pump to make the outlet water flow rate reach the target flow rate; then further obtain the current water temperature at the outlet of the heating chamber; and selectively adjust the heating element according to the current water temperature and the target water temperature.

[0015] In a second aspect, the present invention provides a water purification device, the water purification device including a controller configured to perform the control method for the water purification device described above.

[0016] When the above technical solution is adopted, the present invention can selectively adjust the water temperature or flow rate according to the water outlet data of the heating chamber and the target data. When the water outlet data is not much different from the target data, the water outlet of the heating chamber is connected to the water outlet component to facilitate normal water intake by the user. When the water outlet data is much different from the target data, the water outlet of the heating chamber is connected to the water tank to facilitate the adjustment of water temperature and / or flow rate, preventing water with a large difference from the target data from flowing out of the water outlet component. This avoids excessive deviation between the water outlet data and the target data of the water purifier, greatly improving the user experience.

[0017] Furthermore, compared to setting the water output data only to the water temperature or only to the water flow rate, setting the water output data to both the water temperature and the water flow rate results in a smaller difference between the water flow rate and the target flow rate, as well as between the water temperature and the target temperature, thus further improving the user experience.

[0018] Furthermore, compared to directly comparing the outlet water temperature with the target water temperature and the outlet water flow rate with the target flow rate, and then selectively connecting the outlet of the heating chamber to the outlet component or water tank based on the comparison results, this method first calculates the difference between the outlet water temperature and the target water temperature, as well as the difference between the outlet water flow rate and the target flow rate. Then, it compares these differences with preset values ​​and selectively connects the outlet of the heating chamber to the outlet component or water tank based on the comparison results. This allows for selective connection of the outlet of the heating chamber to the outlet component or water tank based on the magnitude of the deviation between the outlet water temperature and the target water temperature, and the magnitude of the deviation between the outlet water flow rate and the target flow rate. On the one hand, when the deviation between the outlet water data and the target data is small, connecting the outlet of the heating chamber to the outlet component avoids frequent adjustments that could affect the user's normal water intake. On the other hand, when the deviation between the outlet water data and the target data is large, connecting the outlet of the heating chamber to the water tank prevents the difference between the outlet water data and the target data from being too large, further improving the user experience.

[0019] Furthermore, when △1≤A1 and △2≤A2, it indicates that the difference between the outlet water temperature and the target water temperature is small, and the difference between the outlet flow rate and the target flow rate is also small. In this case, directly connecting the outlet end of the heating chamber to the outlet component can avoid affecting the user's normal water intake.

[0020] Furthermore, if △1 > A1 and / or △2 > A2, it indicates that one of the differences between the outlet water temperature and the target water temperature and the differences between the outlet water flow rate and the target flow rate is large, or both the differences between the outlet water temperature and the target water temperature and the differences between the outlet water flow rate and the target flow rate are large. In this case, the outlet end of the heating chamber is connected to the water tank, thereby avoiding an excessive difference between the outlet water data and the target data of the water flowing out from the outlet component.

[0021] Furthermore, when the outlet of the heating chamber is connected to the water tank, indicating a significant difference between the outlet water data and the target data, the heating element can be adjusted to bring the outlet water temperature to the target temperature, and / or the water pump can be adjusted to bring the outlet water flow rate of the heating chamber to the target flow rate. This allows for timely adjustment of the outlet water temperature and flow rate, resulting in an outlet water temperature and flow rate closer to the target temperature and flow rate, thus further improving the user experience.

[0022] Furthermore, when △1 > A1 and △2 > A2, it indicates that the difference between the outlet water temperature and the target water temperature, as well as the difference between the outlet water flow rate and the target flow rate, are both large. In this case, by adjusting the heating component to reduce the difference between the outlet water temperature and the target water temperature, and by adjusting the water pump to reduce the difference between the outlet water flow rate and the target flow rate, the outlet water temperature and the outlet water flow rate can be made to reach the target water temperature and the target flow rate, thereby reducing the difference between the outlet water data and the target data.

[0023] Furthermore, when △1>A1 and △2≤A2, it indicates that the difference between the outlet water temperature and the target water temperature at the outlet of the heating chamber is large, while the difference between the outlet flow rate and the target flow rate is small. In this case, by adjusting the heating component to reduce the difference between the outlet water temperature and the target water temperature, the outlet water temperature of the water flowing out of the outlet component can reach the target water temperature. Without adjusting the water pump, the adjustment frequency of the water pump can be reduced, saving adjustment time, thereby reducing the user's waiting time and further improving the user experience.

[0024] Furthermore, in the case where △1≤A1 and △2>A2, it indicates that the difference between the outlet water temperature and the target water temperature at the outlet of the heating chamber is small, while the difference between the outlet flow rate and the target flow rate is large. By adjusting the water pump to reduce the difference between the outlet flow rate and the target flow rate, the outlet flow rate of the water flowing from the outlet component reaches the target flow rate. Since the outlet flow rate at the outlet of the heating chamber changes after adjusting the water pump, and the change in outlet flow rate may affect the outlet water temperature, after adjusting the water pump, by further obtaining the current water temperature at the outlet of the heating chamber, and selectively adjusting the heating component according to the current water temperature and the target water temperature, when the difference between the current water temperature and the target water temperature is small, the adjustment frequency of the heating component can be reduced by not adjusting the heating component, thus reducing the user's waiting time. When the difference between the current water temperature and the target water temperature is large, timely adjustment of the heating component can prevent the difference between the outlet water temperature and the target water temperature from becoming too large after adjusting the water pump.

[0025] Furthermore, the water purification device provided by the present invention, based on the above technical solution, includes the control method for water purification devices described above, and thus possesses the beneficial effects of the control method for water purification devices described above. Compared with the water purification device before the improvement, the water temperature and flow rate of the water purification device of the present invention are more consistent with the target water temperature and the target flow rate, the difference in water output data is smaller, the water output effect is better, the user's waiting time is shorter, and the user's user experience is better.

[0035] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0036] It should be noted that in the description of this invention, terms such as "upper" and "lower," which indicate direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly, for example, referring to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] Please see Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of a water circuit system for a drinking water purification device according to Embodiment 1 of the present invention. Figure 1 The diagram shows the water flow direction between the outlet of the heating chamber and the outlet component. Figure 2 This is a schematic diagram of the structure of a water circuit system for a drinking water purification device according to Embodiment 1 of the present invention. Figure 2 The diagram shows the water flow path connecting the outlet of the heating chamber to the water tank. Figure 3 This is a schematic diagram of the structure of a second embodiment of the water circuit system for a drinking water purification device according to the present invention. Figure 1 The diagram shows the water flow direction between the water outlet of the heating chamber and the water outlet component. Figure 4 This is a schematic diagram of the structure of a second embodiment of the water circuit system for a drinking water purification device according to the present invention. Figure 2 The diagram shows the water flow path connecting the outlet of the heating chamber to the water tank.

[0039] like Figures 1 to 4 As shown, the water system of the present invention includes a water tank 1, a water pump 2, a heating component 3, a detection component 4, and a water outlet component 5. The heating component 3 has a heating chamber (not shown in the figure). The water pump 2 is used to pump water from the water tank 1 into the heating chamber through the water inlet 31 of the heating chamber. The heating component 3 can heat the water in the heating chamber. The water outlet 32 ​​of the heating chamber can selectively communicate with the water outlet component 5 or the water tank 1.

[0040] With this setup, when the water output data at the outlet 32 ​​of the heating chamber differs significantly from the target data, the outlet 32 ​​of the heating chamber is connected to the water tank 1. This prevents hot water with significantly different output data (outlet water temperature and / or flow rate) from flowing out of the outlet component 5. Furthermore, by adjusting the operating parameters of the water pump 2 and / or the heating component 3, the water output data (outlet water temperature and / or flow rate) at the outlet 32 ​​of the heating chamber is regulated. When the water output data (outlet water temperature and / or flow rate) at the outlet 32 ​​of the heating chamber is close to the target data (target water temperature and / or flow rate), the outlet 32 ​​of the heating chamber is connected to the outlet component 5. This ensures that the water output data from the outlet component 5 is more consistent, greatly improving the user experience.

[0041] It should be noted that, in practical applications, those skilled in the art can configure the heating component 3 as an instant heating tube, wherein a heating chamber is formed inside the instant heating tube, and the instant heating tube can heat the water inside the tube. Alternatively, the heating component 3 can be configured as a box and a heating element, wherein a heating chamber is formed inside the box, the heating element is located inside the box, and the heating component 3 can heat the water inside the box, etc. Such adjustments and changes to the specific configuration type of the heating component 3 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0042] Preferably, the heating element 3 is an instant heating tube, wherein a heating chamber is formed inside the instant heating tube, and the instant heating tube can heat the water inside the tube.

[0043] It should be noted that, in practical applications, those skilled in the art can configure the water pump 2 as a booster pump, or as a self-priming pump, etc. Such adjustments and changes to the specific configuration of the water pump 2 do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0044] Preferably, the water pump 2 of the present invention is a self-priming pump.

[0045] It should be noted that, in practical applications, those skilled in the art can configure the water tank 1 as just a tank body, wherein the water in the water tank 1 is room temperature water, or the water tank 1 can be configured to include a tank body and a heating element, wherein the heating element can preheat the water in the water tank 1, and the water in the water tank 1 is warm water, etc. Such adjustments and changes to the specific configuration of the water tank 1 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0046] Preferably, the water tank 1 includes a tank body and a heating element (not shown in the figure) disposed inside the water tank 1, the heating element being capable of heating the water inside the water tank 1.

[0047] With this setup, the water in the water tank 1 can be preheated by the heating element, and then the preheated water can be pumped into the heating chamber by the water pump 2. The water in the heating chamber can then be heated by the heating element 3, thereby improving heating efficiency and reducing user waiting time.

[0048] Preferably, such as Figures 1 to 4 As shown, a temperature sensor 11 is also installed in the water tank 1 to detect the water temperature inside the water tank 1.

[0049] It should be noted that the present invention does not impose any restrictions on the specific water connection method in which the water outlet 32 ​​of the heating chamber is selectively connected to the water outlet component 5 or the water tank 1. As long as the water outlet 32 ​​of the heating chamber can be selectively connected to the water outlet component 5 or the water tank 1, it does not deviate from the principle and scope of the present invention and should be included within the protection scope of the present invention.

[0050] In one specific embodiment, such as Figure 3 and Figure 4 As shown, the water system also includes a first outlet pipe 61, a return pipe 7, a first control valve 611, and a second control valve 71. One end of the first outlet pipe 61 is connected to the outlet end 32 of the heating chamber, and the other end of the first outlet pipe 61 is connected to the outlet component 5. One end of the return pipe 7 is connected to the outlet end 32 of the heating chamber, and the other end of the return pipe 7 is connected to the water tank 1. The first control valve 611 is installed on the first outlet pipe 61, and the second control valve 71 is installed on the return pipe 7.

[0051] When the water outlet 32 ​​of the heating chamber is connected to the water tank 1 (e.g.) Figure 4 As shown), the first control valve 611 is closed and the second control valve 71 is opened, allowing water from the heating chamber to flow into the water tank 1 to prevent water with significantly different output data from flowing out of the water outlet component 5; when the water outlet end 32 of the heating chamber is connected to the water outlet component 5 (as shown), the first control valve 611 is closed and the second control valve 71 is opened, allowing water from the heating chamber to flow into the water tank 1 to prevent water with significantly different output data from flowing out of the water outlet component 5; Figure 3As shown, the first control valve 611 is opened and the second control valve 71 is closed, so that water in the heating chamber flows out from the water outlet component 5 for use.

[0052] In another specific embodiment, such as Figure 1 and Figure 2 As shown, the water system also includes a first outlet pipe 61, a return pipe 7, and a first three-way valve 8. The first end 81 of the first three-way valve is connected to the outlet end 32 of the heating chamber, the second end 82 of the first three-way valve is connected to the outlet component 5 through the first outlet pipe 61, and the third end 83 of the first three-way valve is connected to the water tank 1 through the return pipe 7. The first end 81 of the first three-way valve can selectively connect to the second end 82 or the third end 83 of the first three-way valve.

[0053] When the water outlet 32 ​​of the heating chamber is connected to the water tank 1 (e.g.) Figure 2 As shown), the first end 81 of the first three-way valve is connected to the third end 83 of the first three-way valve, and the water in the heating chamber flows into the water tank 1 to prevent water with a large difference between the output water data and the target water data from flowing out of the water outlet component 5; when the water outlet end 32 of the heating chamber is connected to the water outlet component 5 (as shown), the water in the heating chamber flows into the water tank 1 to prevent water with a large difference between the output water data and the target water data from flowing out of the water outlet component 5. Figure 1 As shown, the first end 81 of the first three-way valve is connected to the second end 82 of the first three-way valve, and the water in the heating chamber flows out from the water outlet component 5 for use.

[0054] It should be noted that although both of the above embodiments can selectively connect the water outlet 32 ​​of the heating chamber to the water outlet component 5 or the water tank 1, setting the water system to include the first water outlet pipe 61, the return pipe 7, the first control valve 611 and the second control valve 71 can improve the convenience of water circuit switching compared to setting the water system to include the first water outlet pipe 61, the return pipe 7 and the first three-way valve 8. At the same time, it can also simplify the pipe connection of the water system and further improve the user experience.

[0055] The following describes a specific embodiment of the present invention in detail, taking as an example how the water outlet of the heating element is selectively connected to the water outlet component 5 or the water tank 1 by setting a first water outlet pipe 61, a return pipe 7 and a first three-way valve 8.

[0056] like Figure 1 and Figure 2 As shown, the water system of the present invention also includes a one-way valve 72, which is installed on the return pipe 7 to prevent water in the water tank 1 from flowing back to the first three-way valve 8 through the return pipe 7.

[0057] By setting a one-way valve 72, when the water outlet 32 ​​of the heating chamber is connected to the water tank 1, the water in the water tank 1 can be prevented from flowing back to the first three-way valve 8 through the return pipe 7, thereby further improving the user experience.

[0058] It should be noted that in practical applications, the outlet of the water pump 2 can be connected only to the inlet 31 of the heating chamber, or the outlet of the water pump 2 can be configured to selectively connect to the inlet 31 of the heating chamber or the outlet component 5, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0059] Preferably, such as Figures 1 to 4 As shown, the outlet end of the water pump 2 can be selectively connected to the inlet end 31 of the heating chamber or the outlet component 5.

[0060] With this configuration, when the outlet of the water pump 2 is connected to the inlet 31 of the heating chamber, the water in the water tank 1 can be pumped into the heating chamber. After being heated by the heating element 3, the water is delivered to the outlet element 5 and flows out for the user to use hot water. When the outlet of the water pump 2 is connected to the outlet element 5, the water pump 2 can directly pump the water in the water tank 1 into the outlet element 5 for the user to use warm water. This enables the water purifier to have two water temperature output modes, further enhancing the user experience.

[0061] In one specific embodiment, the water system includes a connecting pipe 9, a second outlet pipe 62, and a second three-way valve 10 (e.g., Figures 1 to 4 As shown, the first end 101 of the second three-way valve is connected to the outlet end of the water pump 2, the second end 102 of the second three-way valve is connected to the outlet component 5 through the second outlet pipe 62, and the third end 103 of the second three-way valve is connected to the inlet end 31 of the heating chamber through the connecting pipe 9. The first end 101 of the second three-way valve can selectively connect to the second end 102 or the third end 103 of the second three-way valve.

[0062] When a user takes hot water, the first end 101 of the second three-way valve is connected to the third end 103 of the second three-way valve. The water pump 2 pumps the water in the water tank 1 into the heating chamber. After being heated by the heating component 3, the water is delivered to the water outlet component 5 and flows out.

[0063] When the user takes warm water, the first end 101 of the second three-way valve is connected to the second end 102 of the second three-way valve, and the water pump 2 pumps the water in the water tank 1 directly into the water outlet component 5 and out of the water outlet component 5.

[0064] In another specific embodiment, the water system includes a connecting pipe 9, a second outlet pipe 62, a third control valve, and a fourth control valve (not shown in the figure). The first end of the connecting pipe 9 and the first end of the second outlet pipe 62 are both connected to the outlet end of the water pump 2. The second end of the connecting pipe 9 is connected to the inlet end 31 of the heating chamber. The second end of the second outlet pipe 62 is connected to the outlet component 5. The third control valve and the fourth control valve are respectively installed on the connecting pipe 9 and the second outlet pipe 62.

[0065] Although both of the above embodiments allow the outlet of the water pump 2 to selectively connect with the inlet 31 and outlet component 5 of the heating chamber, setting the water system to include the connecting pipe 9, the second outlet pipe 62 and the second three-way valve 10 makes the switching of the water outlet mode more convenient and simplifies the pipe connection of the water system compared to setting the water system to include the connecting pipe 9, the second outlet pipe 62, the third control valve and the fourth control valve.

[0066] Preferably, the water system includes a connecting pipe 9, a second outlet pipe 62, and a second three-way valve 10.

[0067] It should be noted that, in practical applications, those skilled in the art can configure the water outlet component as a water spout, or as a faucet, etc. Such adjustments and changes to the specific configuration type of the water outlet component do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0068] Preferably, such as Figures 1 to 4 As shown, the water outlet component 5 of the present invention includes a body 51 and a water outlet 52. The body 51 has a water outlet 511, and the water outlet 52 is connected to the water outlet 511.

[0069] See next Figure 5 , Figure 5 This is a flowchart of the control method for a water purification device according to the present invention.

[0070] like Figure 5 As shown, the control method for a water purification device of the present invention includes the following steps:

[0071] S1: Obtain the water outlet data of the water outlet 32 ​​of the heating chamber;

[0072] S2: Obtain the target data corresponding to the effluent data;

[0073] S3: Based on the water output data and target data, selectively connect the water outlet 32 ​​of the heating chamber to the water outlet component or water tank.

[0074] With this setup, the water temperature or flow rate can be selectively adjusted based on the water output data from the outlet 32 ​​of the heating chamber and the target data. When the water output data is close to the target data, connecting the outlet 32 ​​of the heating chamber to the outlet component 5 facilitates normal water intake for the user. When the water output data differs significantly from the target data, connecting the outlet 32 ​​of the heating chamber to the water tank 1 facilitates adjustment of the water temperature and / or flow rate, preventing water with a large discrepancy from flowing out of the outlet component 5. This avoids excessive deviation between the water output data and the target data of the water purifier, greatly improving the user experience.

[0075] It should be noted that selectively connecting the water outlet 32 ​​of the heating chamber to the water outlet component 5 or the water tank 1 means selectively connecting the water outlet 32 ​​of the heating chamber to the water outlet component 5 or connecting the water outlet 32 ​​of the heating chamber to the water tank 1.

[0076] It should be noted that, in practical applications, those skilled in the art can obtain target data corresponding to the water output data based on the information entered by the user on the touch panel of the water purifier, or they can obtain target data corresponding to the water output data based on the information entered by the user on a mobile device that is connected to the water purifier, etc. Such adjustments and changes to the specific method of obtaining the target data do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0077] Preferably, the step of "acquiring target data corresponding to the effluent data" specifically includes:

[0078] The system obtains target data corresponding to the water output data based on the information entered by the user on the touch panel of the water purifier.

[0079] It should be noted that, in practical applications, the water output data of the water outlet 32 ​​of the heating chamber can be obtained by the detection value of the detection component 4 set at the water outlet of the heating chamber, or the water output data of the water outlet 32 ​​of the heating chamber can be obtained by the detection value of the detection component 4 set at the downstream end of the heating component 3, etc. Such adjustments and changes to the specific method of obtaining the water output data of the heating chamber do not deviate from the principle and scope of the present invention, and should all be included within the protection scope of the present invention.

[0080] Preferably, the water outlet data of the heating chamber is obtained by the detection value of the detection component 4 located at the downstream end of the heating component 3.

[0081] With this arrangement, compared to placing the detection component 4 at the outlet 511 of the heating chamber, placing the detection component 4 at the downstream end of the heating element 3 facilitates the installation of the detection component 4 and reduces the processing difficulty of the water purification equipment.

[0082] It should be noted that, in practical applications, those skilled in the art can set the outlet water data to outlet water temperature, and correspondingly, the target data to target water temperature; or, the outlet water data can be set to outlet water flow rate, and correspondingly, the target data to target flow rate; or, the outlet water data can be set to outlet water temperature and outlet water flow rate, and correspondingly, the target data to target water temperature and target flow rate, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0083] See next Figure 6 , Figure 6 This is a flowchart of an embodiment of the control method for a water purification device according to the present invention.

[0084] Preferably, such as Figure 6 As shown, the effluent data includes effluent water temperature and flow rate, while the target data includes target water temperature and target flow rate.

[0085] The steps for “obtaining the water outlet data at the outlet 32 ​​of the heating chamber” include:

[0086] S11: Obtain the outlet water temperature and flow rate of the outlet water end 32 of the heating chamber;

[0087] The steps for "obtaining target data corresponding to effluent data" include:

[0088] S21: Obtain the target water temperature corresponding to the outlet water temperature and obtain the target flow rate corresponding to the outlet water flow rate;

[0089] The step of "selectively connecting the water outlet 32 ​​of the heating chamber to the water outlet component 5 or the water tank 1 based on the water outlet data and target data" specifically includes:

[0090] Based on the outlet water temperature and target water temperature, as well as the outlet water flow rate and target flow rate, the outlet end 32 of the heating chamber is selectively connected to the outlet component 5 or the water tank 1.

[0091] By setting the water output data to both water temperature and flow rate, compared to setting only the water temperature or only the water flow rate, setting the water output data to both water temperature and flow rate results in a smaller difference between the water flow rate and the target flow rate, as well as between the water temperature and the target temperature, thus further improving the user experience.

[0092] It should be noted that, in practical applications, those skilled in the art can configure the detection component 4 as an integrated sensor, wherein the integrated sensor can detect the water flow rate and water temperature at the outlet 32 ​​of the heating chamber. Alternatively, the detection component 4 can be configured as a flow detection component 42 and a water temperature detection component 41, wherein the flow detection component 42 is used to detect the water flow rate at the outlet 32 ​​of the heating chamber, and the water temperature detection component 41 is used to detect the water temperature at the outlet 32 ​​of the heating chamber, etc. Such adjustments and changes to the specific configuration of the detection component 4 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0093] Preferably, such as Figures 1 to 4 As shown, the detection component 4 includes a water temperature detection component 41 and a flow rate detection component 42. The water temperature detection component 41 is used to detect the water temperature at the outlet end 32 of the heating chamber, and the flow rate detection component 42 is used to detect the water flow rate at the outlet end 32 of the heating chamber.

[0094] With this configuration, compared to setting the detection component 4 as an integrated sensor, setting the detection component 4 as a water temperature detection component 41 and a flow rate detection component 42 can make the detection of water temperature and flow rate at the outlet 32 ​​of the heating chamber more accurate. At the same time, when the water temperature detection component 41 or the flow rate detection component 42 fails, the replacement cost can be reduced, thereby reducing the user's maintenance cost.

[0095] It should be noted that, in practical applications, those skilled in the art can place the water temperature detection component 41 upstream of the flow detection component 42, or they can place the water temperature detection component 41 downstream of the flow detection component 42, etc. Such adjustments and changes to the specific placement of the water temperature detection component 41 and the flow detection component 42 do not deviate from the principles and scope of the present invention, and should all be included within the protection scope of the present invention.

[0096] Preferably, the water temperature detection component 41 is located at the upstream end of the flow detection component 42.

[0097] With this setup, compared to placing the water temperature detection component 41 downstream of the flow detection component 42, placing the water temperature detection component 41 upstream of the flow detection component 42 allows for the detection of the outlet water temperature at the outlet 32 ​​of the heating chamber before detecting the outlet water flow rate at the outlet 32 ​​of the heating chamber, thereby improving the accuracy of the outlet water temperature detection.

[0098] It should be noted that, in practical applications, those skilled in the art can set the water temperature detection component 41 as an NTC sensor, or as a thermometer, etc. Such adjustments and changes to the specific setting type of the water temperature detection component 41 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0099] Preferably, the water temperature detection component 41 is an NTC sensor.

[0100] It should be noted that, in practical applications, those skilled in the art can configure the flow detection component 42 as a flow sensor, or as a flow meter, etc. Such adjustments and changes to the specific configuration of the flow detection component 42 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0101] Preferably, the flow detection component 42 is a flow meter.

[0102] It should be noted that, in practical applications, those skilled in the art can compare the outlet water temperature with the target water temperature, and compare the outlet water flow rate with the target flow rate. Based on the comparison results, they can selectively connect the outlet end 32 of the heating chamber to the outlet component 5 or the water tank 1. Alternatively, they can first calculate the difference between the outlet water temperature and the target water temperature, and the difference between the outlet water flow rate and the target flow rate, and then compare this difference with a preset value. Based on the comparison results, they can selectively connect the outlet end 32 of the heating chamber to the outlet component 5 or the water tank 1. Or, they can first calculate the ratio of the outlet water temperature to the target water temperature, and the ratio of the outlet water flow rate to the target flow rate, and then compare this ratio with a preset value. Based on the comparison results, they can selectively connect the outlet end 32 of the heating chamber to the outlet component 5 or the water tank 1, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0103] Preferably, such as Figure 6 As shown, the step of "selectively connecting the outlet end 32 of the heating chamber to the outlet component 5 or the water tank 1 according to the outlet water temperature, target water temperature, outlet flow rate, and target flow rate" specifically includes:

[0104] S31: Calculate the first difference △1 = |T-T0|;

[0105] S32: Calculate the second difference △2 = |Q - Q0|;

[0106] S33: Compare the first difference △1 with the first preset value A1;

[0107] S34: Compare the second difference △2 with the second preset value A2;

[0108] S35: Based on the comparison results, selectively connect the water outlet 32 ​​of the heating chamber to the water outlet component 5 or the water tank 1;

[0109] Where T is the outlet water temperature of the heating chamber outlet 32, T0 is the target water temperature corresponding to the outlet water temperature T, Q is the outlet water flow rate of the heating chamber outlet 32, Q0 is the target flow rate corresponding to the outlet water flow rate Q, A1≥0, A2≥0.

[0110] This setup, compared to directly comparing the outlet water temperature with the target water temperature and the outlet water flow rate with the target flow rate, and selectively connecting the outlet end 32 of the heating chamber to the outlet component 5 or the water tank 1 based on the comparison results, first calculates the difference between the outlet water temperature and the target water temperature, as well as the difference between the outlet water flow rate and the target flow rate, then compares these differences with preset values, and selectively connects the outlet end 32 of the heating chamber to the outlet component 5 or the water tank 1 based on the comparison results. This allows for adjustments based on the magnitude of the deviation between the outlet water temperature and the target water temperature, as well as the flow rate. The deviation between the water flow rate and the target flow rate selectively connects the water outlet 32 ​​of the heating chamber to the water outlet component 5 or the water tank 1. On the one hand, when the deviation between the water flow rate and the target flow rate is small, the water outlet 32 ​​of the heating chamber is connected to the water outlet component 5, thereby avoiding frequent adjustments that would affect the user's normal water intake. On the other hand, when the deviation between the water flow rate and the target flow rate is large, the water outlet 32 ​​of the heating chamber is connected to the water tank 1, thereby preventing the difference between the water flow rate from the water outlet component 5 and the target flow rate from being too large, further improving the user experience.

[0111] It should be noted that, in practical applications, those skilled in the art can adjust the specific values ​​of the first preset value A1 and the second preset value A2 based on experience or experimentation.

[0112] For example, the first preset value A1 = 2℃ and the second preset value A2 = 5ml / min.

[0113] Preferably, such as Figure 6 As shown, the step of "selectively connecting the water outlet 32 ​​of the heating chamber to the water outlet component 5 or the water tank 1 according to the comparison results" specifically includes:

[0114] S351: If △1≤A1 and △2≤A2, then make the water outlet 32 ​​of the heating chamber connected to the water outlet component 5.

[0115] With this setting, under the condition that △1≤A1 and △2≤A2, it indicates that the difference between the outlet water temperature and the target water temperature is small, and the difference between the outlet flow rate and the target flow rate is also small. At this time, there is no need to adjust the outlet water temperature and the outlet flow rate, so that the outlet end 32 of the heating chamber is directly connected to the outlet component 5, which can avoid affecting the user's normal water intake.

[0116] Preferably, such as Figure 6 As shown, the step of "selectively connecting the water outlet 32 ​​of the heating chamber to the water outlet component 5 or the water tank 1 according to the comparison results" specifically includes:

[0117] S352: If △1>A1 and / or △2>A2, then connect the water outlet 32 ​​of the heating chamber to the water tank 1.

[0118] With this setting, when △1 > A1 and / or △2 > A2, it indicates that one of the differences between the outlet water temperature and the target water temperature and the difference between the outlet water flow rate and the target flow rate is large, or both the differences between the outlet water temperature and the target water temperature and the difference between the outlet water flow rate and the target flow rate are large. In this case, connecting the outlet end 32 of the heating chamber to the water tank 1 facilitates the adjustment of the outlet water temperature and / or the outlet water flow rate, thereby preventing the difference between the outlet water data and the target data of the water flowing out from the outlet component 5 from being too large.

[0119] Preferably, when the water outlet 32 ​​of the heating chamber is connected to the water tank 1, the control method of the present invention further includes:

[0120] S36: Based on the comparison results, selectively adjust the water pump 2 and / or the heating element 3 to make the outlet water temperature reach the target water temperature and / or make the outlet water flow rate reach the target flow rate.

[0121] With this setup, when the outlet 32 ​​of the heating chamber is connected to the water tank 1, indicating a large difference between the outlet water data and the target data, the heating component 3 is adjusted to bring the outlet water temperature to the target water temperature, and / or the water pump 2 is adjusted to bring the outlet water flow rate of the heating chamber outlet 32 ​​to the target flow rate. This allows for timely adjustment of the outlet water temperature and flow rate, resulting in an outlet water temperature and flow rate closer to the target water temperature and flow rate, further enhancing the user experience.

[0122] Preferably, such as Figure 6 As shown, the step of "selectively adjusting the water pump 2 and / or the heating element 3 according to the comparison results to make the outlet water temperature reach the target water temperature and / or make the outlet water flow rate reach the target flow rate" specifically includes:

[0123] S361: If △1>A1 and △2>A2, then adjust the water pump 2 and the heating component 3 to make the outlet water temperature reach the target water temperature and the outlet water flow rate reach the target flow rate.

[0124] With this setup, when △1>A1 and △2>A2, it indicates that the difference between the outlet water temperature and the target water temperature at the outlet 32 ​​of the heating chamber, as well as the difference between the outlet water flow rate and the target flow rate, are both large. In this case, by adjusting the heating component 3 to reduce the difference between the outlet water temperature and the target water temperature, and by adjusting the water pump 2 to reduce the difference between the outlet water flow rate and the target flow rate, the outlet water temperature and the outlet water flow rate of the water flowing out from the outlet component 5 can reach the target water temperature and the target flow rate, thus reducing the difference in the outlet water data.

[0125] It should be noted that, in practical applications, those skilled in the art can adjust the water pump 2 first and then the heating component 3, or adjust the heating component 3 first and then the water pump 2, or adjust the water pump 2 and the heating component 3 simultaneously, etc. Such adjustments and changes to the specific adjustment methods of the water pump 2 and the heating component 3 do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0126] Preferably, the water pump 2 is first adjusted to make the water flow rate reach the target flow rate, and then the heating component 3 is adjusted to make the water temperature reach the target water temperature.

[0127] With this setup, compared to adjusting the heating element 3 first and then the water pump 2, adjusting the water pump 2 first and then the heating element 3 can avoid the influence of adjusting the water flow rate on the water temperature, thus making the adjustment of the water temperature and water flow rate more accurate.

[0128] Preferably, such as Figure 6 As shown, the step of "selectively adjusting the water pump 2 and / or the heating element 3 according to the comparison results to make the outlet water temperature reach the target water temperature and / or make the outlet water flow rate reach the target flow rate" specifically includes:

[0129] S362: If △1>A1 and △2≤A2, then adjust the heating element 3 to make the outlet water temperature reach the target water temperature, and do not adjust the water pump 2.

[0130] With this setting, when △1>A1 and △2≤A2, it indicates that the difference between the outlet water temperature and the target water temperature at the outlet 32 ​​of the heating chamber is large, while the difference between the outlet flow rate and the target flow rate is small. In this case, by adjusting the heating component 3 to reduce the difference between the outlet water temperature and the target water temperature, the outlet water temperature of the water flowing out from the outlet component 5 can reach the target water temperature. Without adjusting the water pump 2, the adjustment frequency of the water pump 2 can be reduced, saving adjustment time, thereby reducing the user's waiting time and further improving the user experience.

[0131] Preferably, such as Figure 6As shown, the step of "selectively adjusting the water pump 2 and / or the heating element 3 according to the comparison results to make the outlet water temperature reach the target water temperature and / or make the outlet water flow rate reach the target flow rate" specifically includes:

[0132] S363: If △1≤A1 and △2>A2, then first adjust water pump 2 to make the water flow rate reach the target flow rate;

[0133] S364: Further obtain the current water temperature at the outlet 32 ​​of the heating chamber;

[0134] The heating element 3 is selectively adjusted according to the current water temperature and the target water temperature.

[0135] With this setup, under the condition that △1≤A1 and △2>A2, it indicates that the difference between the outlet water temperature and the target water temperature at the outlet 32 ​​of the heating chamber is small, while the difference between the outlet flow rate and the target flow rate is large. By adjusting the water pump 3 to reduce the difference between the outlet flow rate and the target flow rate, the outlet flow rate of the water flowing from the outlet component 5 reaches the target flow rate. Since the outlet flow rate at the outlet 32 ​​of the heating chamber changes after adjusting the water pump 2, and the change in outlet flow rate may affect the outlet water temperature, after adjusting the water pump 2... By further obtaining the current water temperature at the outlet 32 ​​of the heating chamber, and selectively adjusting the heating element 3 according to the current water temperature and the target water temperature, when the difference between the current water temperature and the target water temperature is small, the adjustment frequency of the heating element 3 can be reduced by not adjusting the heating element 3, thus reducing the user's waiting time; when the difference between the current water temperature and the target water temperature is large, timely adjustment of the heating element 3 can prevent the difference between the outlet water temperature of the water flowing out of the outlet element 5 and the target water temperature from being too large after adjusting the water pump 2.

[0136] It should be noted that, in practical applications, those skilled in the art can directly compare the current water temperature with the target water temperature and selectively adjust the heating element 3 based on the comparison result. Alternatively, they can first calculate the difference between the current water temperature and the target water temperature, then compare the difference with a preset value, and selectively adjust the heating element 3 based on the comparison result. Or, they can first calculate the ratio between the current water temperature and the target water temperature, then compare the ratio with a preset value, and selectively adjust the heating element 3 based on the comparison result, and so on. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should all be included within the protection scope of the present invention.

[0137] Preferably, such as Figure 6 As shown, the step of "selectively adjusting heating element 3 according to the current water temperature and the target water temperature" specifically includes:

[0138] S365: Calculate the third difference △3 = |Td - T0|;

[0139] S366: Compare the third difference △3 with the third preset value A3;

[0140] Based on the comparison results, the heating element 3 is selectively adjusted;

[0141] Where Td is the current water temperature, T0 is the target water temperature, and A3≥0.

[0142] Compared to directly comparing the current water temperature with the target water temperature and selectively adjusting the heating element 3 based on the comparison result, this setting allows for a more intuitive and selective adjustment of the heating element 3 based on the magnitude of the difference between the current and target water temperatures. On one hand, when the difference between the current and target water temperatures is small, the heating element 3 is not adjusted, reducing the adjustment frequency and thus decreasing user waiting time. On the other hand, when the difference between the current and target water temperatures is large, timely adjustment of the heating element 3 can prevent an excessive difference between the outlet water temperature and the target water temperature.

[0143] It should be noted that in practical applications, the third preset value A3 can be set to be equal to the first preset value A1, or the third preset value A3 can be set to be unequal to the first preset value A1, etc. Such flexible adjustments and changes do not deviate from the principles and scope of the present invention and should be included within the protection scope of the present invention.

[0144] Preferably, the third preset value A3 is equal to the first preset value A1.

[0145] Preferably, such as Figure 6 As shown, the specific steps of "selectively adjusting the heating element based on the comparison results" include:

[0146] S367: If △3≤A3, then heating element 3 is not adjusted.

[0147] With this setting, when △3≤A3, it means that after adjusting the water pump 2, the difference between the current water temperature and the target water temperature at the outlet 32 ​​of the heating chamber is relatively small. In other words, the adjustment of the water pump 2 does not cause a significant change in the water temperature at the outlet 32 ​​of the heating chamber. At this time, not adjusting the heating component 3 can reduce the adjustment frequency of the heating component 3, thereby reducing the user's waiting time and further improving the user experience.

[0148] For example, if △1≤A1 and T≥T0, △2>A2 and Q<Q0, then first adjust the water pump 2 to increase the water flow rate at the outlet 32 ​​of the heating chamber. Without adjusting the heating component, the water temperature at the outlet 32 ​​of the heating chamber will inevitably decrease. If the water temperature at this time decreases but still satisfies △1≤A1, then the heating component 3 is not adjusted.

[0149] Preferably, such as Figure 6 As shown, the specific steps of "selectively adjusting the heating element 3 based on the comparison results" include:

[0150] S368: If △3>A3, then adjust heating element 3.

[0151] With this setting, when △3>A3, it indicates that the difference between the current water temperature and the target water temperature is relatively large. By adjusting the heating component 3 in a timely manner to reduce the difference between the current water temperature and the target water temperature, the water temperature flowing out of the water outlet component 5 can be made close to the target water temperature, thus avoiding the excessive difference between the water temperature and the target water temperature caused by adjusting the water pump 2.

[0152] It should be noted that in practical applications, the heating power of the heating element 3 can be adjusted to make the outlet water temperature reach the target water temperature, or the input voltage of the heating element 3 can be adjusted to make the outlet water temperature reach the target water temperature, etc. Such adjustments and changes to the specific adjustment parameters of the heating element 3 do not deviate from the principle and scope of the present invention and should be included within the protection scope of the present invention.

[0153] Preferably, the step of "adjusting the heating element 3 to make the outlet water temperature reach the target water temperature" specifically includes:

[0154] Adjust the heating power of heating component 3 to make the outlet water temperature reach the target water temperature.

[0155] Specifically, when △1 > A1, the control method of the present invention further includes the following steps:

[0156] Determine if the outlet water temperature is higher than the target water temperature;

[0157] Based on the judgment result, adjust the heating power of heating component 3.

[0158] With this setting, when △1 > A1, it means that there is a large difference between the outlet water temperature and the target water temperature. At this time, by judging the difference between the outlet water temperature and the target water temperature, the heating power of the heating component 3 can be accurately adjusted, so that the outlet water temperature can be quickly adjusted to the target water temperature, further improving the user experience.

[0159] Preferably, the specific steps of "adjusting the heating power of the heating element 3 according to the judgment result" include:

[0160] If the judgment result is "yes", then reduce the heating power of heating component 3;

[0161] If the judgment result is "no", then the heating power of heating component 3 will be increased.

[0162] With this setting, if the judgment result is "yes", it means that the current outlet water temperature is higher than the target water temperature, that is, the outlet water temperature is too high. By reducing the heating power of the heating element 3, the outlet water temperature can be lowered, thereby quickly adjusting the outlet water temperature to the target water temperature. If the judgment result is "no", it means that the current outlet water temperature is lower than the target water temperature, that is, the outlet water temperature is too low. By increasing the heating power of the heating element 3, the outlet water temperature can be raised, thereby quickly adjusting the outlet water temperature to the target water temperature.

[0163] It should be noted that in practical applications, the water flow rate can be adjusted by adjusting the power of the water pump 2 to achieve the target flow rate, or by adjusting the input voltage of the water pump 2 to achieve the target flow rate, or by adjusting the rotation speed of the water pump 2 to achieve the target flow rate, and so on. Such adjustments and changes to the specific adjustment parameters of the water pump 2 do not deviate from the principles and scope of this invention and should be included within the protection scope of this invention.

[0164] Preferably, the step of "adjusting water pump 2 to make the outlet water temperature reach the target water temperature" specifically includes:

[0165] Adjust the input voltage of water pump 2 to make the outlet water temperature reach the target water temperature.

[0166] Specifically, when △2 > A2, the control method of the present invention further includes the following steps:

[0167] Determine if the outflow rate is greater than the target flow rate;

[0168] Based on the judgment result, adjust the input voltage of water pump 2.

[0169] With this setting, when △2 > A2, it means that there is a large difference between the outflow rate and the target flow rate. At this time, by judging the magnitude of the outflow rate and the target flow rate, the input voltage of water pump 2 can be accurately adjusted, thereby quickly adjusting the outflow water temperature to the target water temperature and further improving the user experience.

[0170] Preferably, the specific steps of "adjusting the input voltage of water pump 2 according to the judgment result" include:

[0171] If the judgment result is "yes", then reduce the input voltage of water pump 2;

[0172] If the judgment result is "no", then increase the input voltage of water pump 2.

[0173] With this setting, if the judgment result is "yes", it means that the current water flow rate is greater than the target flow rate, that is, the water flow rate is too high. By lowering the input voltage of water pump 2, the water flow rate can be reduced, thereby quickly adjusting the water flow rate to the target flow rate. If the judgment result is "no", it means that the current water flow rate is less than the target flow rate, that is, the water flow rate is too low. By raising the input voltage of water pump 2, the water flow rate can be increased, thereby quickly adjusting the water flow rate to the target flow rate.

[0174] The following describes in detail specific embodiments of the control method for water purification equipment of the present invention in conjunction with the following situations.

[0175] The target water temperature is set to 40℃, the target flow rate is 400ml / min, the first preset value A1 = 2℃, the second preset value A2 = 5ml / min, and the third preset value A3 = 2℃.

[0176] Scenario 1:

[0177] Outlet water temperature T = 41℃, Q = 403ml / min

[0178] Then △1=|T-T0|=|41℃-40℃|=1℃<A1;

[0179] △2=|Q-Q0|=|403-400|=3ml / min<A2;

[0180] At this time, the water outlet 32 ​​of the heating chamber is connected to the water outlet component 5.

[0181] Scenario 2:

[0182] Outlet water temperature T = 45℃, Q = 403 ml / min

[0183] Then △1=|T-T0|=|45℃-40℃|=5℃>A1;
