[0029] In addition, the heating assembly 3 comprises a heating disc 31 fixedly connected inside the cabinet 1, a coffee boiler 32 and a steam boiler 33, the steam boiler 33 is fixedly arranged with the steam rod 12, the coffee boiler 32 is fixedly arranged with the variable-temperature brewing head 21 and the constant-temperature brewing head 22 respectively, the heating disc 31 is arranged between the variable-temperature brewing head 21 and the coffee boiler 32, and the temperature control member 23 adjusts the heating power ratio between the heating disc 31, the coffee boiler 32 and the steam boiler 33 by detecting the water flow temperature entering the variable-temperature brewing head 21 and the constant-temperature brewing head 22.

[0030] The power of the heating disc 31 is not more than 1700W, and the power of the coffee boiler 32 and the steam boiler 33 is 1700W.

[0031] In the embodiment, the coffee boiler 32 is used for heating coffee liquid, the steam boiler 33 is used for heating internal water to provide steam for the steam rod 12, the working principle of the temperature control member 23 is to detect the water flow temperature entering the variable-temperature brewing head 21 and the constant-temperature brewing head 22, compare with the preset temperature, and control the on-off state of the heating disc 31, the coffee boiler 32 and the steam boiler 33, the temperature control member 23 is electrically connected with the intelligent control system in the control screen, the temperature control member 23 comprises a temperature sensor, when the temperature control member 23 detects that the water temperature does not reach the preset value, the heating assembly 3 is controlled to increase the power, so as to realize accurate control of the water temperature, and then high-quality coffee is extracted;

[0032] When the temperature control member 23 adjusts the power of the heating disc 31, the coffee boiler 32 and the steam boiler 33 in the heating assembly 3, the following control logic is followed:

[0033] When making drinks, the coffee boiler 32 and the steam boiler 33 can heat at the same time, at this time, the overall power of the device is 3400W, and the conventional power supply can support the normal operation of the device; when the variable-temperature brewing head 21 and the constant-temperature brewing head 22 work at the same time, the heating disc 31 and the coffee boiler 32 can heat at the same time, according to the power ratio of the heating disc 31 and the coffee boiler 32, the overall power of the device is not more than 3600W; when the variable-temperature brewing head 21 and the constant-temperature brewing head 22 work at the same time, and the steam rod 12 is used to whip milk, the temperature control member 23 preferentially ensures the heating of the heating disc 31 and the coffee boiler 32, ensures the stability of the water temperature of the two groups of brewing heads, and the steam boiler 33 adopts a cooling priority and polling heating work algorithm to ensure the stability of the steam and the extraction water temperature, so as to realize the ability and stability of continuous coffee production under the condition of conventional power supply;

[0034] The core idea of the above algorithm is that when the power is limited, the temperature stability of the key components is preferentially guaranteed, and the cooling or delay heating strategy is adopted for other non-key components to avoid overload. The states of the heating disc 31, the coffee boiler 32 and the steam boiler 33 are periodically detected, and the heating priority is dynamically adjusted according to the real-time demand. For example, when the steam rod 12 is started, the algorithm polls the priority of the steam boiler 33, and reduces the power of the heating disc 31 and the coffee boiler 32.

[0035] Further, the inside of the cabinet 1 is provided with a water supply assembly 4 for adjusting the extraction water pressure when making coffee.

The drip tray 8 is used to receive the liquid flowing down from the cups above the warm cup plate 7 to avoid flowing into the heating assembly 3.

[0040] The working principle of the device is as follows:

[0041] In the process of making coffee, when the temperature control piece 23 detects that the coffee temperature in the brewing assembly 2 does not reach the preset value, the coffee boiler 32 is started to heat the output coffee, and when only the constant temperature brewing head 22 is used, the coffee boiler 32 and the steam boiler 33 can be heated at the same time; When the variable temperature brewing head 21 and the constant temperature brewing head 22 work at the same time, the temperature control piece 23 controls the heating disc 31 and the coffee boiler 32 to heat at the same time, if the steam rod 12 is not used at this time, the temperature control piece 23 controls the power of the steam boiler 33 to reduce, to ensure that the heating disc 31 and the coffee boiler 32 can normally heat; When the variable temperature brewing head 21 and the constant temperature brewing head 22 work at the same time, and the steam rod 12 needs to be used, the temperature control piece 23 preferentially ensures the heating of the heating disc 31 and the coffee boiler 32, ensures the stability of the water temperature of the two groups of brewing heads coffee extraction, and the steam boiler 33 adopts the cooling priority and polling heating work algorithm, ensures the stability of the steam and the extraction water temperature, so as to realize the ability and stability of continuous coffee production under the condition of conventional power supply.
