ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention concerns an electrically operable automatic tea-making machine comprising a stand, a cold water container and a tea-preparation chamber.
A simple tea-making machine is known in which tea water is heated, evaporates, condenses, and the condensed water is guided through a tea filter from above to below. Due to the long condensing period, this machine operated tea jar has, however, not succeeded.
SUMMARY OF THE INVENTION
The invention has the object to provide a tea-making machine by which tea can be prepared repeatedly in an automatic way in a very short time and according to any formulation desired. Furthermore, it should be able to be used for any hot beverage where in the course of its preparation a flavor is extracted. This object is achieved by the electrically operable automatic tea-making machine which comprises a stand, a cold water container and a tea-preparation chamber, a sucking tube communicating with said cold water container and a pump and further with a heating chamber and the end of an outflow tube, which leads from said heating chamber, being arranged above said tea preparation chamber which is subdivided in a circular segmental shape by a removable tea strainer and into which a removable propeller of an agitator is inserted, an electronic control unit for controlling all tea-making operations being arranged behind a control panel.
