A waterway structure of the milk powder brewing machine comprising a water storage tank, a plurality of cooling pipes, a thick-film heater and a constant-temperature bin. A water inlet and outlet are formed in the water storage tank, and a spiral pipe is arranged in each cooling pipe. Water flowing from the water outlet is divided and respectively flows into water inlet of each cooling pipe of the plurality of cooling pipes. After the water flowing out from water outlets of the plurality of cooling pipes join together, the water flows into the thick-film heater to be heated to a temperature of 90-100° C. The hot water flows into the spiral pipe to be cooled and flows into the constant-temperature bin after being cooled to a preset temperature. The waterway structure of the present disclosure enhances the cooling effect, realizes instant heating, achieves reuse of energy, and improves the energy-saving effect.

The coffee machine (1) comprises a resting surface (6) for cups (7, 7′) and a hydraulic circuit having in cascade a pump, a boiler, an infusion head (3) and a filter holder cup (4) removably engaged with the infusion head (3), also being provided a mobile support structure (8) for supporting the assembly formed by the infusion head (3) and the filter holder cup (4), and a movement means (17) for moving the support structure (8) between a plurality of positions to which different distances of the filter holder cup (4) from the resting surface (6) correspond.

Beverage supply apparatus 100 has tank 3, heating device 6 for heating pipe L31 in milk supply pipe L3 through which a beverage (milk or foamed milk) flows, and first pump 7. When the beverage supply is completed, apparatus 100 fills pipe L3 with water, and enters into a standby state. When the standby state continues for a predetermined time, apparatus 100 discharges the water inside pipe L3 through drain pipe L4, and then again fills pipe L3 with water. Additionally, when a supply instruction is input during the standby state, the beverage supply apparatus 100 discharges the water through the drain pipe L4, discharges the beverage from the drain pipe L4 by a predetermined amount, and then delivers the beverage from the beverage delivery port 10 through the outlet pipe L33.

A coffee machine including a main body including a circuit for dispensing coffee having an inlet that can be hydraulically connected to a water supply line; a central processing and control unit configured to control at least the circuit for dispensing coffee; a communication interface configured to connect with a telecommunications network; a sensor system for the detection of parameters related to possible operation anomalies or failures of the coffee machine provided inside the main body; a peripheral processing unit at least connected to the sensor system and configured to carry out a first local processing of the data detected by the sensors and to send the locally processed data to one or more remote server by the communication interface.

A water passage structure includes a water heating device and a brewing head. The brewing head includes a drainage inlet, a water passage chamber, a drainage outlet and a water supply channel. The water passage chamber is communicated with the drainage inlet and the drainage outlet. The water supply channel is located adjacent to and isolated from the water passage chamber. The drainage inlet and a water inlet of the water supply channel are each controllable to be communicated with a water outlet of the water heating device. The water heating device can firstly discharge hot water into the water passage chamber to preheat the brewing head, and after the brewing head is preheated, the water heating device supplies hot water through the water supply channel, so as to meet the requirements of stable temperature of the first outlet water.
