The intelligent water shortage monitoring and soft protecting method of the coffee machine described in fig. 1 can be applied to an intelligent water shortage monitoring and soft protecting system and device of the coffee machine, the method can also be applied to an intelligent coffee machine, a water tank of the coffee machine is provided with a photoelectric sensor for detecting water shortage, and the photoelectric sensor is not in direct contact with water in the water tank. Specifically, a light-permeable rhombic equilateral triangle is arranged at the vertical wall of the water tank, a photoelectric sensor is arranged at the rhombic equilateral triangle, and the emitting end of the photoelectric sensor is positioned in the rhombic triangle. Through the rhombic triangle structure capable of transmitting light and isolating water, the photoelectric sensor can accurately detect the water storage state in the water tank without barriers, and therefore the non-contact design of the photoelectric sensor and the water storage is realized. The non-contact design solves the problem of difficulty in cleaning the photoelectric sensor, and simultaneously ensures the complete water level detection function. In addition, as shown in fig. 1, the intelligent water shortage monitoring and soft protecting method of the coffee machine may include the following operations:

In the embodiment of the invention, specifically, the water level in the water tank is intelligently detected through the photoelectric sensor transmitting end, wherein when the water level detection information corresponding to the transmitting end indicates that the water level is lower than the photoelectric sensor transmitting end, the water tank is judged to be free of water or the residual water amount is extremely small (for example, only 1% of the total water storage amount of the water tank is left), and the water tank corresponds to the first water level state; when the water level detection information corresponding to the transmitting end indicates that the water level is higher than or equal to the transmitting end of the photoelectric sensor, the water tank is judged to have water, and the water tank corresponds to the non-first water level state.

Further, when the current water level of the water tank is judged to be in a first water level state or a non-first water level state, the first water level state can correspond to a first height of the transmitting end of the photoelectric sensor; the non-first water level state may correspond to the second height of the emitting end of the photoelectric sensor, that is, two different water level height values are set as more accurate determination states of the remaining water volume of the water tank. Further, the first height and the second height can be respectively divided into a plurality of small height division sections, so that the residual water quantity in the water tank can be determined more precisely.

102. When the water level state of the water tank is determined to be the first water level state, according to a preset water shortage soft protection program, water shortage control operation is executed on the coffee machine so as to prompt a user that the coffee machine needs to be added with water, and the water shortage control operation comprises water shortage prompt and/or water discharge forbidden control.

In the process of controlling the photoelectric sensor according to the first sensing control parameter, the detection of the water replenishment by the photoelectric sensor may be performed continuously, preferably, once every 5s, which is not limited in the embodiment of the present invention.

switching the water shortage indicator lamp of the coffee machine to be in a continuous flashing state according to the second lamp control parameter; meanwhile, all functions of the coffee machine which need water are forbidden forcedly according to the water outlet control parameters;

and then controlling the photoelectric sensor to carry out water supplementing detection according to the second sensing control parameter until the water level of the water tank is determined to be in a state other than the first water level, switching the water shortage indicator lamp of the coffee machine to be in a normally dark state, and simultaneously recovering all functions of the coffee machine which need water.

In this alternative embodiment, when the water level state of the water tank is in the second sub-state (the water tank of the coffee machine is already close to being unable to discharge water), if the operation of the coffee machine is not interrupted in time by the user at this time, all water using functions of the terminal coffee machine are forced by the water discharge control parameter, so that dry burning prevention and water pump air pumping prevention functions are realized. Meanwhile, the water shortage prompting lamp is switched to a state of continuous flashing so as to strongly remind a user of water shortage of the water tank, and further, the buzzer can be controlled to output a water shortage prompting sound while the water shortage prompting lamp is controlled to strongly remind through the built-in buzzer. In addition, the second sensing control parameter needs to be set to timely detect the water replenishment of the coffee machine, and for the control flow of the water replenishment detection, please refer to the control flow of the above embodiment, and the embodiments of the present invention are not described herein.

In the optional embodiment, the water level state of the water tank is in the second sub-state, the water level of the water tank is close to 0, and the user still continues to operate the coffee machine, and a forced control program is set at the moment, so that on one hand, the continuous flashing lamp is used for strongly reminding that the coffee machine is in the water shortage state, and the reminding intensity of the user for definitely determining that the water tank is in the water shortage state is improved; the water outlet forced disabling program can force to disable all water using functions of the coffee machine, timely start the functions of preventing idle burning and preventing idle pumping of the water pump of the coffee machine, and is beneficial to improving the use safety of the coffee machine and prolonging the service life; further, after the completion of water supplementing of the water tank is detected, the water-lack prompting lamp can be timely adjusted to be dark, the water-using function of the coffee machine is recovered, and the display accuracy and timeliness of the water-lack prompting lamp and the recovery and forbidden accuracy of the water-using function of the coffee machine are improved.
