Fig. 1 is a structural diagram of a control system of a beverage machine according to an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following embodiments.
As shown in fig. 1, the control system of the beverage machine in the embodiment includes a machine body, and a water tank 1, a water pump 2, an air pump 3, a heater 4, a brewing chamber 5, a beverage output nozzle 6, a first three-way valve 7, a second three-way valve 8, a control circuit board, and a safety valve 9 disposed in the machine body.
Wherein the output of water tank 1 is connected with the input of water pump 2, and first three-way valve 7 is connected with water pump 2, air pump 3, heater 4 respectively, and second three-way valve 8 is connected with heater 4, brewing chamber 5 and relief valve 9 respectively to relief valve 9 still is connected with beverage output mouth 6, and brewing chamber 5's export is connected with beverage output mouth 6.

Whether the check valve 71 is installed or not is selected according to the length of the connection pipe between the air pump 3 and the first three-way valve 7, and when the connection pipe between the air pump 3 and the first three-way valve 7 is long, a one-way valve 71 for guiding the air pump 3 toward the first three-way valve 7 is installed on a connection pipe between the air pump and the first three-way valve 7, and when it is used normally, the water output from the water pump 2 flows into the connection pipe between the first three-way valve 7 and the air pump 3, because the connecting pipeline is longer, the water storage amount in the connecting pipeline is larger, when the air pump 3 works, the stored water in the connecting pipeline needs to be blown out, the working time of the air pump 3 is increased, the one-way valve 71 can be disposed near the first three-way valve 7, so that water output by the water pump 2 can be effectively prevented from entering a connection pipeline between the first three-way valve 7 and the air pump 3, and thus the working time of the air pump 3 can be effectively reduced. When the connecting pipeline between the air pump 3 and the first three-way valve 7 is short, the first three-way valve 7 does not need to be installed, even if water output by the water pump 2 enters the connecting pipeline between the first three-way valve 7 and the air pump 3, the water stored in the connecting pipeline is very limited, and therefore the air pump 3 can blow out the water in the connecting pipeline between the first three-way valve 7 and the air pump 3 in a short time.
In addition, the arrangement position of the air pump 3 in the embodiment is combined, so that the air pump 3 can discharge the liquid in the output end of the water pump 2, the heater 4 and the brewing cavity 5 completely from the beverage output nozzle 6 in a short time, the calcification of the residual water in the heater 4 is prevented, the heating efficiency of the heater 4 is correspondingly improved, and the taste of the output beverage is also improved.
The safety valve 9 can release the excessive pressure input by the air pump 3 or the water pump 2, and avoids the abnormal working phenomena of cup frying, cracking and the like of capsules placed in the brewing cavity 5 due to unstable working pressure of the air pump 3 or the water pump 2 caused by commercial power fluctuation. Meanwhile, the led pressure relief liquid can be conveyed to the position of the beverage output nozzle 6 and then is output to the placed cup body through the beverage output nozzle 6, so that the liquid output by the pressure relief of the beverage machine cannot pollute the table top of a user. And a check valve 81 which is communicated towards the brewing chamber 5 is also connected between the second three-way valve 8 and the brewing chamber 5. The non-return valve 81 prevents the liquid in the brewing chamber 5 from flowing back into the heater 4 and prevents the heater 4 from being contaminated by the liquid in the brewing chamber 5.
In addition, in the working process, if the water pump 2 or the air pump 3 has overlarge output pressure due to power supply voltage fluctuation, the pressure water can enable a passage communicated with the safety valve 9 in the second three-way valve 8 to be communicated, so that the pressure water is discharged from the beverage output nozzle 6 through the safety valve 9, abnormal working phenomena such as cup frying and cracking of capsules placed in the brewing cavity 5 are avoided, and the stability and the safety of a beverage machine control system are ensured.

The temperature of the inlet water detected by the first temperature sensor 41 and the temperature of the outlet of the heater 4 detected by the second temperature sensor 42 can effectively control the heating parameters such as the heating frequency and the heating time of the heater 4 and the PWM value of the work of the water pump 2, so that the temperature of the water output from the heater 4 to the brewing cavity 5 can more accurately reach the set water temperature. The first temperature sensor 41 and the second temperature sensor 42 in this embodiment can adopt NTC high-precision temperature control devices, and the temperature monitoring operation of the first temperature sensor 41 and the second temperature sensor 42 can ensure that the heating temperature of the heater 4 does not reach the liquid vaporization temperature and the temperature of the beverage at the end of the beverage output nozzle 6 is not lower than the set value.
In addition, in order to ensure the safe operation of the heater 4 and avoid the damage of the heater 4 caused by dry burning, a temperature controller or a temperature fuse electrically connected with the control circuit board is arranged on the heater 4. When the temperature of the heater 4 exceeds the set temperature, the temperature controller or the temperature fuse is turned off, and the operating circuit of the heater 4 is cut off, so that the heater 4 stops heating.
In order to prevent the heater 4 from being burnt dry and the vaporization phenomenon after the user adjusts the water tank 1, a water level switch 11 for detecting the low water level in the water tank 1 can be arranged in the water tank 1, the water level switch 11 is electrically connected with a control circuit board, when the water in the water tank 1 is too little or has no water, the control circuit board can cut off the work of the heater 4 according to the signal of the water level switch 11, and the condition that the heater 4 is burnt dry is avoided.
In addition, in order to further prevent the heater 4 from being burnt dry and the phenomenon of vaporization after the user adjusts the water tank 1, a detection switch 12 for detecting whether the water tank 1 is installed in place is arranged in the machine body corresponding to the position where the water tank 1 is installed, and the detection switch 12 is electrically connected with the control circuit board. When the detection switch 12 detects that the water tank 1 is not placed in place, the control circuit board controls the heater 4 to be switched off, so that the situation that the water tank 1 is dry-boiled due to the fact that the water tank 1 cannot normally output water to the heater 4 is avoided.
