Description

Espresso coffee machine {Espresso coffee machine}

The present invention relates to an espresso coffee machine, and more particularly, to an espresso coffee machine capable of extracting espresso coffee in commercial and home.

According to the background art of the coffee extracting apparatus of Korean Patent No. 10-0920237, a coffee beverage made using a coffee bean is divided into an instant coffee and a coffee bean largely. The coffee beans are divided into drip coffee and espresso coffee depending on the extraction method.

In particular, espresso refers to a method of extracting coffee in a short time by providing high-pressure hot water to ground coffee beans, and coffee extracted through such a method. The apparatus for extracting espresso coffee comprises a porta filter for containing coffee ground beans and a boiler and a pump for supplying hot water to coffee beans. Conventional espresso coffee extracting apparatuses are known in various forms depending on the purpose and size of use, such as a coffee shop, an industrial office, a meeting room, or a home.

On the other hand, factors that determine the flavor of espresso coffee include kinds of coffee beans, roasted coffee beans, and the size of the ground coffee beans. In addition to the above factors, hot water temperature and pressure when extracting espresso coffee from an espresso coffee extracting apparatus is also a factor that greatly influences. For example, a conventional espresso coffee extractor extracts espresso coffee under hot water at a temperature of about 90 DEG C and pressure of 8 to 10 atmospheres.

However, the conventional espresso coffee extracted using hot water has a problem in that the temperature and pressure of the hot water supplied to extract the coffee are constant, and the taste of the coffee extracted according to the taste of the user can not be changed.

In addition, since the head portion of the coupling portion of the potter filter for extracting coffee by receiving hot water is exposed to the atmosphere, the coffee extracting time is delayed because the coffee is lowered at the temperature set by the machine user and the coffee can not be extracted.

In addition, the user can not confirm the shape of the extracted coffee and the amount of the discharged coffee, so that there is a problem that an abnormal symptom of the extracting part from which the coffee is extracted can not be confirmed in advance.

The present invention is characterized in that a group head for extracting coffee is provided with a variable pressure controller in the main body and a heating body for varying the pressure of hot water supplied to the potato filter so that the group head can be maintained at a temperature desired by the user, The user can check the shape of the extracted coffee and the coffee extract by attaching a mirror to the bottom of the cradle at the bottom. The user can check the temperature of the water supplied to the group head and the porta filter, the amount of water supplied, The present invention provides an espresso coffee machine capable of storing the same information.

The present invention relates to a display device, A water tank provided inside the main body and storing water for making coffee; A boiler unit provided in the main body and heating water supplied from the water tank using a heater; A pump for supplying water stored in the water tank to the boiler section; A pota filter accommodating the ground coffee powder and having an extraction port at the bottom for discharging the extracted coffee; A group head connected to the porta filter and supplied with water from the boiler portion to an upper portion of the porta filter and having an outlet for discharging the water supplied to the porta filter to the lower portion; The group head is provided inside the group head to prevent the group head exposed to the outside of the main body from being cooled to prevent the hot water supplied from the boiler part from being cooled while passing through the group head due to cooling of the group head And a heating body for holding the heating body; And a variable pressure controller which is provided in the main body and varies the pressure of water supplied to the group head, wherein the variable pressure controller varies the pressure of the hot water supplied to the porter filter and the group head, And the taste of the coffee extracted with the filter is controlled.

In the espresso coffee machine according to the present invention, a lower portion of one side of the main body is provided with a cradle for supporting a coffee container for receiving coffee discharged through the extraction port from the bottom, And a mirror capable of confirming the shape of the coffee to be extracted and the coffee extract to be discharged can be attached to one side of the cradle.

The espresso coffee machine according to the present invention may further include a steam nozzle for heating the milk or the like using the hot water stored in the boiler unit and a steam control valve for controlling the heat of the hot water stored in the boiler unit supplied to the steam nozzle A boiler unit temperature gauge for informing the user of the temperature of the boiler unit at a side of the main body, a pressure gauge for informing a user of the pressure of water supplied to the group head, And a memory unit connected to the pump and storing information such as the temperature of the water supplied to the group head, the amount of water to be supplied, the pressure of the supplied water, and the coffee extraction time, , Hot water stored in the boiler portion is discharged to the outside of the main body at one side of the main body A hot water nozzle and a hot water control valve for regulating the amount of hot water discharged to the outside through the hot water nozzle, and an extraction control lever for controlling the extraction of coffee may be provided at one side of the group head.
