COFFEE MACHINE WITH TEMPERATURE ADJUSTMENT AND CONTROL UNIT

Abstract

The coffee machine consists of a pump (1) which is connected to the coffee group (6) via a heat exchanger (2) installed in the boiler (3). A volumetric sensor (9) is mounted on the pump (1) and a volumetric sensor (11) and a valve (12) for filling the boiler (3) are installed between the pump (1) and the heat exchanger (2). An adjustable valve (13) for the water flow is installed between the heat exchanger (2) and the coffee group (6). A permanent magnet (16) is fixed to the handle (7), as well as an identification sensor (17) and a temperature sensor (18) are installed in the coffee assembly (6). The coffee machine also includes a unit for temperature regulation and control (19), which receives and / or sends signals from / to the temperature sensor (18), the identification sensor (17), the solenoid valve (15), the pump (1) and the volumetric sensors (9) and (11).The temperature regulation and control unit (19) is also connected to a server (25), the water level sensor (20) and the water pressure sensor (21) in the boiler (3), the adjustable valve (13), the heating elements (4) in the boiler (3), the temperature sensor.
