Automatic water adding method of full-automatic water adding kungfu tea machine and tea machine

Abstract

The invention discloses an automatic water adding method of a full-automatic water adding kungfu tea machine and the tea machine. The tea machine comprises a computer controller, a display, a controlkeyboard, a kettle with a dry-burning-resistant low-water-level sensor and a temperature sensor, and a boiling-overflow-resistant high-water-level sensor. The tea machine is automatically controlled according to the following steps of a, presetting the longest control time T for adding water each time in a computer memory; b, manually selecting water temperature control parameters for boiling water on the keyboard; c, entering an automatic water adding / boiling one-key instruction; d, controlling a water nozzle to turn on a water pump or an electromagnetic valve to feed water at the water adding position of the kettle and starting accumulative timing t by the computer; e, judging whether the water adding accumulative time t reaches the longest control time T or not in real time by the computer, and if yes, going to the step g, otherwise, going to the step f; f, detecting whether the water level in the kettle reaches the highest limited water level H or not by the computer, and if yes, going to the step g, otherwise, going to the step e; and g, controlling the water pump or the electromagnetic valve to stop adding water by the computer. The tea machine adopting the method can automatically control the kettle to add the water when no water exists or heat the water through a one-key instruction, so that the water pump does not perform no-water pumping, the kettle does not perform no-water heating, the water does not overflow, and the tea machine is reliable, practical, labor-saving and intelligent.

Description

technical field [0001] The invention relates to a civil tea set, in particular to an automatic watering method for a fully automatic watering kung fu tea machine and a tea machine using the method. Background technique [0002] The kung fu tea machines of the prior art, including the kettle (or kettle) due to the special structure of the kettle, generally only have an anti-dry temperature relay located at the bottom of the kettle or an electrode-type low water level sensor detected based on the principle of water conduction. The high water level of water is generally controlled by software timing through the time of adding water, instead of using a high water level sensor. This is because the small space is rich in steam and the water is tumbling or full of conductive steam when adding water and boiling water, which is not easy to detect accurately. Non-contact sensors such as float balls cannot be used at all. The steam is not easy to detect accurately, and because the ele...

AI Technical Summary

Problems solved by technology

Since the full and high water level cannot be measured reliably, when the water source is cut off or the waterway is blocked and the water cannot be added or the water cannot be filled, the so-called water shortage automatic water heating device that relies on time to quantitatively add water is actually not automatic at all. The function of filling up the water is a sick product, which is criticized by the market
