[0024] If the steaming teapot is placed within the heat preservation time T3, the temperature of the steaming teapot is determined after the steaming teapot is placed. If the temperature inside the steaming teapot is above 80 degrees Celsius, the process re-enters the tea-making and heat preservation stage. If the temperature inside the steaming teapot is below 80 degrees Celsius, steps S221 and S222 are repeated.

[0025] If the steaming teapot is not placed or picked up within the heat preservation time T3, the tea-making step is exited.

[0026] Preferably, the tea steaming step comprises:

[0027] Step S231: before steaming tea, add water into the steaming teapot, heat the water in the steaming teapot to 100° C., and heat the water according to the mapping relationship between the temperature and power of the steaming teapot during the heating process;

[0059] To make the technical problems solved, the technical solutions adopted, and the technical effects achieved by the present invention more clearly understood, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It is apparent that the described embodiments are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0060] The embodiment of the present invention provides a method for controlling water heating, steaming and brewing tea. Figure 5As shown, the hardware device required to implement the control method includes at least a workbench 1, on which a control module 2 and a display screen 3 are provided. The control module 2 includes a switch module 21, a double-click water adding module 25, a water boiling temperature adjustment module 22, a tea boiling time setting module 23, and a steaming tea time setting module 24; a first coupler 5 is provided on the workbench 1; a second coupler 6 is provided on the workbench 1; a kettle can be placed on the first coupler 5, and a millimeter wave probe and an NTC probe are provided at the bottom of the kettle; a steaming teapot can be placed on the second coupler 6, and an NTC probe is provided at the bottom of the steaming teapot; and a water adding component 4 is provided on the workbench 1. The switch module 21 is used to turn the entire hardware device on and off. The double-click water-adding module 25 is used to issue a water-adding mode command. When the double-click water-adding module 25 is activated, the water-adding component 4 will add water to the kettle and / or steaming teapot. The water-adding component 4 primarily comprises a water pump and a water-adding pipe. The water pump draws water from an external source and delivers it to the kettle and / or steaming teapot through the water-adding pipe. The water-boiling temperature control module 22 is used to issue a water-boiling mode command. The tea-steaming timing module 24 is used to issue a tea-steaming mode command. The tea-brewing timing module 23 is used to issue a tea-brewing mode command. In this embodiment of the present invention, the steaming and boiling tea operations share the same steaming teapot and the same second coupler 6, so the steaming and boiling operations need to be separate. It should be noted that the steaming and boiling operations can also be performed using separate kettles and different couplers. In this embodiment, the millimeter-wave probe is used to detect the water level in the kettle, and the NTC probe is used to detect the temperature.

[0061] like Figure 1 As shown, an embodiment of the present invention provides a method for controlling water boiling, steaming and brewing tea, comprising:

[0062] Step S1: receiving a mode instruction issued by a user; it should be noted that the mode instruction is issued by the control module 2;

[0063] Step S2: The mode instruction includes a water boiling mode instruction, a tea brewing mode instruction, or a tea steaming mode instruction. When the water boiling and temperature control module 22 is triggered, the water boiling mode instruction is issued. When the tea brewing setting module 23 is triggered, the tea brewing mode instruction is issued. When the tea steaming setting module 24 is triggered, the tea steaming mode instruction is issued. If the received mode instruction is the water boiling mode instruction, the water boiling step is executed. If the received mode instruction is the tea steaming mode instruction, the tea steaming step is executed. If the received mode instruction is the tea brewing mode instruction, the tea brewing step is executed.

[0064] Among them, such as Figure 2 As shown, the water boiling step includes:

[0065] Step S211: Detect the water level in the kettle through the millimeter wave probe. If the water level is lower than the preset threshold N, add water first. The preset threshold N refers to the height of the water level, preferably 16 mm. After adding water until the water level exceeds the preset threshold N or reaches the preset target water level, boil the water. Before boiling the water, judge the water level in the kettle. Only when it exceeds the lowest threshold water level will the water boiling step be performed to prevent dry boiling. Setting the preset target water level can be achieved by controlling the double-clicking water adding module 25; boil water to the set temperature. The set temperature defaults to 100°C. The set temperature is adjustable. By long pressing the water boiling temperature adjustment module 22 for 2 to 4 seconds, preferably 3 seconds, you can enter the set temperature mode, and then cyclically press the water boiling temperature adjustment module 22 to adjust the temperature. The temperature that can be set is 100℃, 95℃, 90℃, 85℃, 80℃, 75℃, 70℃, 65℃, 60℃, 55℃, 50℃, 45℃, and 40℃. During the boiling process, the water is boiled according to the mapping relationship between the temperature and power in the kettle. The mapping relationship between the temperature and power in the kettle is: the boiling power from room temperature to 92℃ is 1500W, the boiling power from 93℃ to 96℃ is 800W, the boiling power from 97℃ to 98℃ is 500W, and the boiling power from 99℃ to 100℃ is 300W. When boiling water, the water is boiled according to the mapping relationship between the temperature and power in the kettle, and variable power heating is performed to ensure that the water is quickly heated to the set temperature without exceeding it too much. For example, if the boiling point is set to 100℃, it can be boiled for 3 to 5 seconds after reaching 100℃.

[0066] Step S212: While detecting the water level in the kettle by the millimeter wave probe, the temperature in the kettle is detected by the NTC probe; if the temperature in the kettle is ≤50°C, the time for the millimeter wave probe to detect the water level in the kettle is t1, and t1 is 4 to 6 seconds, preferably 5 seconds; if the temperature in the kettle is greater than 50°C but less than 95°C, the time for the millimeter wave probe to detect the water level in the kettle is t2, and t2 is 20 to 30 seconds, preferably 25 seconds; if the temperature in the kettle is ≥95°C but ≤100°C, the time for the millimeter wave probe to detect the water level in the kettle is t3, and t3 is 8 to 12 seconds, preferably 10 seconds. The millimeter wave probe is set at the bottom of the kettle. It calculates the water level based on the time it takes for the wave to be emitted to the water surface and then reflected back. If there are bubbles in the water, the water level cannot be detected or the detected water level is inaccurate. When boiling water, the bubbles in the water are different at different temperatures. Specifically, below 50℃, there are basically no bubbles in the water, so the water detection time is the shortest; when the temperature is 50℃ to 95℃, there are more bubbles in the water, and the millimeter wave has poor penetration of bubbles. Many of the waves emitted are absorbed by the bubbles and cannot return, resulting in poor detection stability and a longer detection time. The test time is repeated to ensure the accuracy and stability of the detection; when the temperature is above 95°C, the influence of bubbles on the millimeter wave is also less, so above 95°C, the water detection time is shorter than that between 50°C and 95°C, but longer than that below 50°C; preferably, under different water detection times, the millimeter wave probe will obtain different test data, and the test data with the highest number of repetitions is taken as the water level height; in the embodiment of the present invention, the NTC probe is used to detect the temperature in the kettle in coordination with the millimeter wave probe, and different water detection times are used according to different temperatures to obtain an accurate water level height.

[0067] In some embodiments, as Figure 2 As shown, the water boiling step further includes:

[0068] Step S213: After the water is boiled to the set temperature, the constant temperature stage is entered. The time for maintaining the constant temperature stage is T1, which can be set, preferably 15 minutes, and the constant temperature power is F1, which is 200W;

[0069] Step S214: After the constant temperature stage T1, exit the water boiling step and enter the standby state;

[0070] If the water boiling mode instruction, tea brewing mode instruction or tea steaming mode instruction is received during the constant temperature stage T1, or the kettle is lifted or placed, the water boiling step is repeated.

[0071] In the embodiment of the present invention, by setting a constant temperature stage, when the water is boiled, even if the user does not use it in time, it can still be maintained at the temperature required by the user; however, after a period of constant temperature, if the user does not operate, it will enter a standby state, and when the hot water is not used, it will avoid the water being kept warm and working all the time, which wastes electricity; at the same time, during the constant temperature stage, if the user lifts the kettle or other instructions indicate that it is necessary to continue boiling water, the water boiling steps will be repeated and the water will continue to be provided for the user to use. Furthermore, if the kettle is lifted and then placed back within 3 seconds, and the millimeter wave probe can detect the water level, heating is performed based on the current water level, unless the current water level is below a preset threshold N. If the millimeter wave probe cannot detect the water level, the water adding component 4 adds water to the kettle, and the added water level is the memorized water level before the kettle was lifted. If the kettle is lifted and then placed back more than 3 seconds later, step S212 is repeated. If the temperature in the kettle is ≤50°C and the water level is not detected within the corresponding water detection time, water is added. If the temperature in the kettle is greater than 50°C but less than 95°C and the water level is not detected within the corresponding water detection time, water is added. If the temperature in the kettle is ≥95°C but ≤100°C and the water level is not detected within the corresponding water detection time, water is added. Because the bubbles in the water in the kettle vary at different temperatures, if the water level is still not detected within the corresponding water detection time, it means that there is no water in the kettle and water needs to be added. It should be noted that if the water heating and temperature adjustment module 22 is touched during the water heating process, the water heating will stop and the system will enter the standby state.

[0072] In some embodiments, Figure 3 As shown, by touching the tea-making time setting module 23, a tea-making mode instruction can be triggered. After receiving the tea-making mode instruction, the tea-making steps are started, and the tea-making steps include:

[0073] Step S221: Before brewing tea, add water to the steaming teapot. Water can be added to the steaming teapot through the water adding component 4 or manually. The water in the steaming teapot is heated to 100°C. During the heating process, the water is heated according to the mapping relationship between the temperature and power of the steaming teapot. The mapping relationship between the temperature and power of the steaming teapot is as follows: the heating power is 650W from room temperature to 92°C, and the heating power is 300W from 93°C to 100°C. Since the focus of brewing tea is to place the tea leaves in the steaming teapot, it is not necessary to quickly make the temperature in the steaming teapot reach 100°C. At the same time, the variable power heating method is adopted in this embodiment, so that after the water temperature in the steaming teapot approaches or reaches 100°C, it is continuously heated at 100°C, that is, it is heated at low power to avoid water spraying.

[0074] Step S222: After the water in the steaming teapot is heated to 100° C., the tea-making process begins. The heating is continued, and the tea-making time T2 is set. T2 can be 5 minutes, 10 minutes, 20 minutes, 30 minutes, 45 minutes, 60 minutes, etc. The tea-making time T2 is adjustable. The tea-making time T2 can be adjusted by long pressing the tea-making time setting module 23 for 2 to 4 seconds. The adjustment method is to continue to press the tea-making time setting module 23 cyclically to select different tea-making times T2. The tea-making process is cyclically heated at a specific tea-making time and a specific tea-making power until the tea-making time T2 is reached, and then the tea-making heat preservation stage is entered.

[0075] The cyclic heating at a specific tea-brewing time and a specific tea-brewing power includes:

[0076] Step S2221: heating at power F4 for a time period of t4. Preferably, power F4 is 200W and t4 is 10 seconds.

[0077] Step S2222: heating at power F5 for a time period of t5. Preferably, power F5 is 100W and t5 is 10 seconds.

[0078] Loop steps S2221 and S2222.

[0079] The loop of steps S2221 and S2222 ensures that the total length of the multiple times t4 and t5 is exactly the set T2.

[0080] In the embodiment of the present invention, the teapot can be effectively prevented from spraying during tea brewing by circulating the tea at different powers for different times.

[0081] In some embodiments, if the steaming teapot is lifted within the set tea-brewing time T2, the water temperature in the steaming teapot is determined after the steaming teapot is put down. If the water temperature is lower than 80°C, a new round of tea-brewing steps is repeated. If the water temperature in the steaming teapot is higher than 80°C after the steaming teapot is put down, the tea-brewing and heat-keeping stage is entered. In the tea-brewing and heat-keeping stage, the heat-keeping temperature is 90°C and the heat-keeping time is T3, preferably 30 minutes.

[0082] If the steaming teapot is placed within the heat preservation time T3, the temperature of the steaming teapot is determined after the steaming teapot is placed. If the temperature inside the steaming teapot is above 80 degrees Celsius, the process re-enters the tea-making and heat preservation stage. If the temperature inside the steaming teapot is below 80 degrees Celsius, steps S221 and S222 are repeated.

[0083] If the steaming teapot is not placed or picked up within the heat preservation time T3, the tea-making step is exited.

[0084] In an embodiment of the present invention, by setting a tea-making and keeping-warm stage and combining it with the user's teapot-lifting action, if the user does not lift the teapot, it indicates that the user does not need to use the steaming teapot. After the keeping-warm stage, the tea-making step is automatically exited, and then the machine is shut down after 30 minutes, which can effectively prevent the steaming teapot from being dry-burned. At the same time, during the tea-making and keeping-warm stage, if the user lifts the teapot, it means that the steaming teapot is being used all the time. Then, the temperature after lifting and putting it down is used to judge whether the current water temperature in the steaming teapot meets the requirements for tea-making, and then automatically decide whether to continue the tea-making and keeping-warm stage or start a new round of tea-making, automatically matching to meet the user's usage needs. It should be noted that if the tea-making setting module 23 is touched during the tea-making process, the tea-making will stop and enter the standby state.

[0085] In some embodiments, as Figure 4 As shown, by touching the tea steaming time setting module 24, a tea steaming mode instruction can be triggered. After receiving the tea steaming mode instruction, the tea steaming step is started, and the tea steaming step includes:

[0086] Step S231: Before steaming tea, water is added to the steaming teapot and heated to 100°C. During the heating process, the water is heated according to the mapping relationship between the temperature and power of the steaming teapot. The mapping relationship between the temperature and power of the steaming teapot is as follows: the heating power is 650W from room temperature to 92°C, and the heating power is 300W from 93°C to 100°C. Since the focus of steaming tea is to place the tea leaves in the steaming teapot, it is not necessary to quickly bring the temperature in the steaming teapot to 100°C. At the same time, the present embodiment adopts a variable power heating method so that the water temperature in the steaming teapot remains at 100°C after approaching or reaching 100°C, that is, it is kept at a low power to avoid water spraying.

[0087] Step S232: After the water in the steaming teapot is heated to 100° C., the tea steaming process begins. The heating is continued, and the tea steaming time is set to T4. T4 can be 7 minutes, 10 minutes, 15 minutes, 20 minutes, etc. The tea steaming time T4 is adjustable. The tea steaming time T4 can be adjusted by long pressing the tea steaming time setting module 24 for 2 to 4 seconds. The adjustment method is to continue to press the tea steaming time setting module 24 cyclically to select different tea steaming times T4. The tea steaming is cyclically heated at a specific tea steaming time and a specific tea steaming power until the tea steaming time T4 is reached, and then the tea steaming and keeping warm phase begins.

[0088] The cyclic heating at a specific tea steaming time and a specific tea steaming power includes:

[0089] Step S2321: heating at power F6 for a time period of t6, preferably, F6 is 0W and t6 is 5 seconds;

[0090] Step S2322: heating at power F7 for a time period of t7, preferably, F7 is 300W and t7 is 10 seconds;

[0091] Loop steps S2321 and S2322.

[0092] The loop of steps S2321 and S2322 ensures that the total length of the multiple times t6 and t7 is exactly the set T4.

[0093] In the embodiment of the present invention, the steaming of tea is circulated at different powers for different times during the steaming process, which can effectively prevent the teapot from spraying during the steaming process.

[0094] In some embodiments, if the steaming teapot is lifted during the set steaming time T4, the water temperature in the steaming teapot is checked after the steaming teapot is put down. If the water temperature is below 80°C, a new round of steaming tea is repeated. If the water temperature in the steaming teapot is above 80°C after the steaming teapot is put down, the steaming tea heat preservation stage is entered. In the steaming tea heat preservation stage, the heat preservation temperature is 90°C and the heat preservation time is T5. Preferably, T5 is 30 minutes.

[0095] If the steaming teapot is lifted or lowered within the heat preservation time T5, the temperature is judged after the steaming teapot is put down; if the temperature inside the steaming teapot is above 80 degrees Celsius, the steaming tea heat preservation stage is re-entered; if the temperature inside the steaming teapot is below 80 degrees Celsius, steps S231 and S232 are repeated.

[0096] In an embodiment of the present invention, by setting a tea steaming and keeping warm stage, and combining it with the user's action of lifting the pot, if the user does not lift the pot, it indicates that the user does not need to use the steaming teapot. After the heat preservation stage, the tea steaming step is automatically exited, and then the machine is shut down after 30 minutes, which can effectively prevent the steaming teapot from being dry-burned. At the same time, during the tea steaming and keeping warm stage, if the user lifts the pot, it means that the steaming teapot is being used all the time. Then, the temperature after lifting and putting it down is used to judge whether the current water temperature in the steaming teapot meets the requirements for steaming tea, and then automatically decide whether to continue the tea steaming and keeping warm stage or start a new round of tea steaming, and automatically match to meet the user's usage needs. It should be noted that if the tea steaming setting module 24 is touched during the tea steaming process, the tea steaming is stopped and the machine enters the standby state.

[0097] In some embodiments, if the temperature detected by the NTC probe in the kettle or the steaming teapot exceeds 110°C, the heating power is cut off and heating is resumed until the kettle or steaming teapot is lifted or placed. When the NTC probe detects that the temperature in the kettle or steaming teapot exceeds 110°C, it indicates that the water is dry-boiling, and the power is automatically cut off to prevent dry-boiling. Furthermore, the system automatically returns to normal operation after the user lifts or places the kettle or steaming teapot, making operation convenient.

[0098] In some embodiments, the mode instruction further includes a water adding mode instruction, and the water adding mode instruction is issued by triggering the double-click water adding module 25. If the received mode instruction is a water adding mode instruction, the water adding step is executed, and the water adding step includes:

[0099] S241: Set the amount of water to be added, and determine whether the water level in the kettle is higher than the set amount of water to be added. If the water level in the kettle is lower than the set amount of water to be added, add water to the kettle until the set amount of water to be added is reached; if the water level in the kettle is higher than the set amount of water to be added, do not add water.

[0100] In an embodiment of the present invention, a millimeter wave probe is used to detect the water level in the kettle, and then a judgment is made based on the set water addition amount to determine whether water needs to be added, and if water is added, whether the set amount can be added exactly. It should be noted that after the water addition step is completed, if there is no other operation, the system automatically enters the standby state. If the water addition module 25 is double-clicked during the water addition process, water addition is stopped. Regarding adjusting the set water addition amount, long press and double-click the water addition module 25 for 2 to 4 seconds to enter the water addition adjustment mode. The water addition amount can be set to 0.3L, 0.4L, 0.5L, 0.6L, 0.7L, 0.8L, 0.9L, 1L, etc. Different water addition amounts can be selected by cyclically triggering and double-clicking the water addition module 25.

[0101] In some embodiments, in shutdown mode, if you long press the water temperature adjustment module 22 for 4 to 6 seconds, you can adjust the boiling point temperature. At this time, continuously clicking the water temperature adjustment module 22 can adjust the boiling point. The boiling point adjustment range is 80°C to 100°C. The user can select the boiling point to adapt to the actual boiling point of different altitudes. Because the boiling point of different altitudes is different, the higher the altitude, the lower the boiling point. For example, in the plateau area, the actual boiling point is 89 degrees. When the water is boiled to 89 degrees, it is still heated at high power. If the boiling point of the water is not adjusted at this time, the heating will not stop, but the water temperature will not rise again at this time, which will eventually cause dry boiling. After the boiling point is adjusted, the embodiment of the present invention can set the target temperature to 89°C, and then the actual 89°C is mapped to 100°C on the display module through an internal algorithm. This can solve the pain point of boiling water in the plateau area. After confirming the selected boiling point, click the switch module 21 to complete the boiling point change.
