Referring to fig. 1, a display screen 19 for displaying water level and water temperature is further arranged at the front end of the intelligent kettle, an input device 20 and a cover 21 for covering the hot water storage container 5 are arranged at the top of the intelligent kettle, and a plurality of control keys are arranged on the input device 20 and comprise a heating key, a target water quantity preset key, a target water temperature preset key and a starting key. Wherein, the user can input the desired target water amount, such as 1/3 cups, half cups, 2/3 cups and full cups, by using the target water amount preset key; the user can input any water temperature between the hot water temperature of 100 deg.c and the cold water temperature of 25 deg.c, for example, 50 deg.c, using the target water temperature preset key.
The intelligent kettle is provided with a controller (not shown in the figure), and the controller is electrically connected with the first flow valve 8, the first flow sensor 9, the second flow valve 11, the second flow sensor 12, the refrigeration module 13, the electromagnetic valve 14, the heating wire 15, the water level monitor 17, the temperature sensor 18, the display screen 19, the input device 20, the camera 22 and the illuminating lamp 23. When the intelligent kettle works, the first flow valve 8, the first flow sensor 9, the second flow valve 11, the second flow sensor 12, the refrigeration module 13, the electromagnetic valve 14, the heating wire 15, the water level monitor 17, the temperature sensor 18, the display screen 19, the input device 20, the camera 22 and the illuminating lamp 23 are controlled by the controller to realize the working process described below. It should be noted that, in this embodiment, only the working process of the relevant components is described, and the control process of the controller is not described again.
In the initial state, the first flow valve 8, the second flow valve 11 and the electromagnetic valve 14 of the intelligent kettle are closed. Before the intelligent kettle works, a user firstly opens the cover 21 to fill the hot water storage container 5 with water, and then presses a heating key of the input device 20 to enable the intelligent kettle to perform heating work. When the intelligent kettle is used for heating, the heating wire 15 is started to heat the water in the hot water storage container 5, so that the water is changed into hot water at 100 ℃. After heating is completed, the electromagnetic valve 14 is opened, so that hot water at the top of the hot water storage container 5 flows into the cold water storage container 6 through the electromagnetic valve 14, hot water at the bottom of the hot water storage container 5 is remained in the hot water storage container 5, and then the refrigeration module 13 starts to cool the hot water in the cold water storage container 6 to form cold water at 25 ℃.
Then all the water level monitors 17 in the hot water storage container 5 are activated. As can be seen from fig. 5, the water level monitor 17 located at the lowest position in the water storage container 5 is attached to the inner bottom surface of the water storage container 5, and therefore, the water levels measured by the six water level monitors 17 in the water storage container 5 are 0L, 1L, 2L, 3L, 4L and 5L in sequence from the top right to the bottom right. In this embodiment, after the hot water at the top of the hot water storage container 5 flows into the cold water storage container 6, 2.5L of hot water is left in the hot water storage container 5, so the water level in the hot water storage container 5 is located between the third water level monitor 17 and the fourth water level monitor 17 from bottom to top, therefore, the three water level monitors 17 disposed at the top of the hot water storage container 5 cannot measure the water level, the three water level monitors 17 disposed at the bottom of the hot water storage container 5 can measure the water level, at this time, the water level 2L measured by the third water level monitor 17 from bottom to top is used as the initial water level, and the measured initial water level in the hot water storage container 5 is displayed on the display screen 19. At the same time the temperature sensor 18 in the hot water reservoir 5 is activated to measure the temperature of the water in the hot water reservoir 5 and the measured temperature of the water in the hot water reservoir 5 is displayed on the display 19. Meanwhile, the initial water level and the water temperature in the cold-storage water container 6 are measured in the same manner, and the measured initial water level and the measured water temperature in the cold-storage water container 6 are displayed on the display screen 19, which will not be described in detail.
When a user needs to take water, a desired target water amount, for example, a half cup, is input by using a target water amount preset key of the input device 20, a desired target water temperature, for example, 50 ℃, is input by using a target water temperature preset key of the input device 20, and the ratio of the water outlet of the hot water at 100 ℃ to the water outlet of the cold water at 25 ℃ is required to be 1:2 by the controller according to the target water temperature (50 ℃). Then, a user presses a start key of the input device 20 to start the camera 22 to take a picture of the cup placing position 3 in real time, and the water cup 2 is placed on the cup placing position 3 and is positioned right below the water outlet 4, so that the water cup 2 exists in the picture of the cup placing position 3 taken by the camera 22 in real time, the controller controls the first flow valve 8 and the second flow valve 11 to open the water outlet 4 accordingly, specifically, the controller controls the opening degree of the first flow valve 8 and the second flow valve 11 to be 1:2 according to the water outlet proportion of 1:2, so that hot water and cold water with the proportion of 1:2 are discharged from the hot water storage container 5 and the cold water storage container 6, and the hot water and the cold water are mixed at the junction of the water outlet hoses 7 and 10 to form mixed water at 50 ℃, and the mixed water is discharged into the water cup 2 through the water outlet 4. It should be noted that, the user can input any target water temperature between the hot water temperature (100 ℃) and the cold water temperature (25 ℃) by using the target water temperature preset key of the input device 20, and the controller can control the hot water discharge amount and the cold water discharge amount by controlling the first flow valve 8 and the second flow valve 11, so as to control the water temperature of the mixed water to be changed between the hot water temperature (100 ℃) and the cold water temperature (25 ℃) at will, and realize stepless temperature adjustment to obtain the target water temperature input by the user.
When the cup 2 exists in the picture of the cup holding position 3 shot by the camera 22 in real time, the camera 22 shoots an initial cup cavity image of the cup 2 on the cup holding position 3, and the camera 22 shoots an initial cup cavity image of the cup 2 when shooting the initial cup cavity image of the cup 2. In the water outlet process, the illuminating lamp 23 is started to illuminate the water cup 2 on the cup placing position 3, the camera 22 absorbs the cup cavity picture of the water cup 2 on the cup placing position 3 in real time, and the controller analyzes the water amount added into the water cup 2 in real time according to the cup cavity picture of the water cup 2, specifically: when the camera 22 takes the picture of the cavity of the cup 2, it takes the picture of the inner wall of the cup 2, when the water cup 2 is filled with water, the light rays between the inner wall of the cup which is submerged by the water and the inner wall of the cup which is not submerged by the water are different, therefore, two different pictures of the inner wall of the cup exist in the pictures of the cup cavity taken by the camera 22, the controller can calculate the proportion of the picture of the inner wall of the cup submerged by water in the pictures of the cup cavity to the initial picture of the inner wall of the cup reversely according to the proportion of the picture of the inner wall of the cup not submerged by water in the pictures of the cup cavity to the initial picture of the inner wall of the cup, namely, the controller can reversely deduce the proportion of the part of the cup cavity filled with water in the cup cavity picture in the initial image of the cup cavity according to the proportion of the part of the cup cavity not filled with water in the cup cavity picture in the initial image of the cup cavity, therefore, the proportion of the water amount in the cup to the capacity of the cup 2 can be obtained, and the water amount in the cup 2 can be obtained. When the water amount in the water cup 2 reaches half of the water amount, the cup cavity with water in the cup cavity picture accounts for half of the initial image of the cup cavity, the controller analyzes that the water amount in the water cup 2 reaches the preset target water amount according to the half of the initial image, at the moment, the first flow valve 8 and the second flow valve 11 are closed, and the water outlet 4 is closed, so that the water supply to the water cup 2 is stopped. Therefore, the final water quantity of the intelligent kettle from the water outlet to the water cup 2 is not a specific water quantity, but is obtained by analyzing the cup cavity picture of the water cup 2 in real time, so that for the water cups 2 with different capacities, the controller can also control the water outlet quantity according to the capacity of the water cup 2 and the real-time water quantity in the water cup 2, the final water quantity of the intelligent kettle from the water outlet to the water cup 2 is in accordance with the preset target water quantity, the water can be added into the water cups 2 with different capacities, and the intelligent kettle can be suitable for the water cups 2 with different capacities.
More simply, the side wall of the cup 2 is vertical, so that during the water outlet process, after the camera 22 takes the picture of the cup cavity of the cup 2, the water quantity in the cup 2 can be obtained by reverse estimation directly according to the height of the inner wall of the cup which is not submerged by water in the cup cavity and the height of the inner wall of the whole cup.
In the present embodiment, after the hot water at the top of the hot-water storage container 5 flows into the cold-water storage container 6, 2.5L of hot water remains in the hot-water storage container 5, but the measured initial water level in the hot-water storage container 5 is 2L, so the measured initial water level deviates from the actual water level. When the hot water storage container 5 starts to discharge water, the water level in the hot water storage container does not immediately drop below the third water level monitor 17 from bottom to top, and the first flow sensor 9 is not started. When the hot water container 5 continues to discharge water until the water level therein drops to just below 2L, the real-time water level in the hot water container 5 can be considered to be equal to the initial water level 2L, and at this time the first flow sensor 9 is activated to measure the subsequent water discharge. After the water outlet is finished, 1.9L of hot water in the hot water storage container 5 is remained, so that the water outlet amount measured by the first sensor 9 is 0.1L, and thus, the controller can accurately calculate the real-time water level 1.9L of the hot water storage container 5 by directly subtracting the subsequent water outlet amount 0.1L from the measured initial water level 2L, and display the real-time water level 1.9L of the hot water storage container 5 on the display screen 19. Likewise, the real-time water level in the cold water storage tank 6 can be measured and displayed on the display screen 19 in the same manner, which will not be described in detail herein.
