The present disclosure relates to the technical field of tea sets, and in particular to an automatic tea cooking and brewing device (an automatic tea brewing and making device).
There is a long history for tea culture, and accordingly, there are various types of tea brewing appliances, for example, a tea cup, a tea bowl, a teapot with a drinking nozzle such as a teapot made of purple clay, etc. Regarding such common tea brewing appliances, the use method is usually to add tea leaves into the tea brewing appliances, and then to add boiling water or hot water to soak them to get tea water, where tea water is drunk with a cup mouth, a bowl mouth or a drinking nozzle provided above the appliance. As the society develops and as people's living standard has been continuously improved, tea sets are constantly introduced with new ones. In recent years, various automatic or semi-automatic tea brewing devices have been widely studied. For example, Chinese patent documents with the Patent Nos.

The use method and working principle of the automatic tea cooking and brewing device of the embodiment are briefly described as follows:
regarding the automatic tea cooking and brewing device of the embodiment in use, a user turns on the power to the device, and first chooses tea cooking or tea brewing through the human-machine interacting module of the controller 95 as needed.
If the user chooses tea cooking, the user first puts the selected tea leaves into the tea leaf filtering piece 22 of the tea cooking and brewing container 2, and then inputs as needed, through the human-machine interacting module of the controller 95, parameters such as water amount for cooking tea, the highest water temperature for cooking tea, and time for cooking tea to the CPU module, correspondingly; and the parameters are sent to the CPU module for storage; the second weighing sensor 94 detects in real time whether the tea holding container 7 has been placed on the second transversal frame 14, and if the tea holding container 7 has been placed on the second transversal frame, after receiving a signal of the second weighing sensor 94, the CPU module activates, through the relay group, the water injection controlling device 6 to inject cold water into the tea cooking and brewing container 2 with tea leaves through the water inlet pipe 3; the first water amount detecting device detects in real time water amount in the tea cooking and brewing container 2, and when the water amount in the tea cooking and brewing container 2 reaches a set value, the controller 95 turns off the power of the water injection controlling device 6 to stop injecting water, and the CPU module of the controller 95 controls, through the relay group, the first electric heating element 5 to power on, so as to heat the water in the tea cooking and brewing container 2; the CPU module of the controller 95 starts timing the time for cooking tea since the power of the first electric heating element 5 is turned on, and the temperature detecting device 91 detects in real time water temperature in the tea cooking and brewing container 2; when the water in the tea cooking and brewing container 2 is heated to a set maximum temperature, the controller 95 maintains the set temperature for continuing the tea cooking through a cooperation control of the temperature detecting device 91 and the first electric heating element 5; when the timing reaches the set time for tea cooking, the sound and light reminder module of the controller 95 sends out sound and light reminders to remind that the tea water is ready for drinking. The controller 95 controls the first electric heating element 5 to power off. At the same time, the CPU module of the controller 95 controls, through the relay group, the electrically controlled valve 4 to power on, so as to start injecting tea water into the tea holding container 7 until the tea water in the tea cooking and brewing container 2 is basically emptied. The second weighing sensor 94 monitors in real time the tea water amount added into the tea holding container 7 and feeds back a signal to the CPU module in real time. After the tea water in the tea holding container 7 reaches a set amount, the CPU module closes the electrically controlled valve 4 through the relay group to stop discharging tea water, and the user drinks tea through the tea holding container 7.
If the user chooses tea brewing, the difference from the foregoing tea cooking lies in that water is first added to the tea cooking and brewing container 2, and then water is heated to a set temperature and then power of the first electric heating element 5 is automatically turned off; then the selected tea leaves are put into the tea leaf filtering piece 22 of the tea cooking and brewing container 2 to brew tea, and time for tea brewing is timed, and tea water is automatically discharged when the set time is reached.
During use, if the tea water in the tea holding container 7 gets cold and needs to be heated, the tea holding container 7 may be placed on the second transversal frame 14, and through operating the human-machine interaction module of the controller 95, the second electric heating element 8 controlled by the controller 95 is started to power on, so as to heat the tea holding container 7, avoiding waste.
