PURPOSE: An espresso coffee machine is provided to enable a group head to maintain the temperature, which is required by a user, by including a band heater inside the group head. CONSTITUTION: An espresso coffee machine includes a main body (110), a water tank, a boiler unit, a pump, a portafilter (120), a group head (130), and a band heater (132). The boiler unit is provided inside the main body, and uses a heater to heat water which is supplied from the water tank. The pump supplies the boiler unit with water which is stored in the water tank. The portafilter accommodates ground coffee, and comprises an extraction port through which extracted coffee is discharged. The group head is connected to the portafilter; supplies the upper part of the portafilter with water which is supplied from the boiler unit; and is equipped with an outlet (136) which discharges the water supplied from the portafilter to the lower side. The band heater is provided inside the group head, and prevents the group head from being cooled. |
