FIELD: beverage making.
SUBSTANCE: invention relates to an automatic machine for making hot beverages. The automatic machine for making hot beverages contains a water source, a hot water boiler for heating water, a unit for hot beverage dosing, and a hydraulic water supply circuit. The hydraulic water supply circuit contains the first outlet pipe for connecting the water source and the hot water boiler, the second outlet pipe for connecting the hot water boiler and the unit for hot beverage dosing, at least the first electronically controlled valve device for selective supplying water to the second outlet pipe, and a water temperature sensor for measuring the water temperature at an outlet of the hot water boiler. The hydraulic water supply circuit additionally contains the fourth outlet pipe for connecting the first outlet pipe and the second outlet pipe. The hydraulic water supply circuit additionally contains the second electronically controlled valve device for selective supplying water to the fourth outlet pipe. The second outlet pipe contains a collector for water supply located between the hot water boiler and the first and the second valve devices, wherein the first and the second valve devices have corresponding water outlets connected to the collector for water supply. The dosing unit contains a set of dosing devices for dosing corresponding types of hot beverages. The hydraulic water supply circuit also contains a set of the first mentioned valve devices, one for each dosing device. The first valve devices are located next to each other to form a compact valve assembly, and they have corresponding inlets connected in parallel to the collector for water supply, and corresponding outlets connected to corresponding dosing devices. The first valve devices are physically connected together in such a way that corresponding internal channels form, in general, the collector for water supply. The second valve device is located downstream from the first valve devices in the direction, along which hot water passes into the collector for water supply. The automatic machine for making hot beverages additionally contains an electronic control unit electrically connected to the water temperature sensor and to the first and the second valve devices, and made with the possibility of controlling the first and the second valve devices based on the water temperature at the outlet of the hot water boiler to forcibly prevent the supply of hot water to the unit for hot beverage dosing through the second outlet pipe and the first valve device until the first and the second valve devices reach a predetermined thermal mode, to supply it to the third outlet pipe through the second valve device for heating the first and the second valve devices and bringing them into the mentioned thermal mode.
EFFECT: maintaining the temperature necessary for dosing the corresponding hot beverage.
