Machine For Brewing Tea

#In general, a tea bag or tea powder placed in a sieve container is immersed in hot water or hot water is poured over the tea bag or tea powder for the preparation of a cup of tea and after a certain brewing time the tea as a beverage is ready for serving and drinking. During this preparation an unnecessary amount of electrical energy is consumed, as often more water than the required amount for a cup of tea is heated and the preparation of tea is often associated with sophisticated handling operation: firstly, water has to be poured into a container in which it is heated, thereafter the heated water has to be added to the tea which is contained in a tea bag, which is contained in a cooking vessel and subsequently, after the tea preparation is completed, the tea bag has to be removed from the cooking vessel. Only then, the tea can be consumed as a beverage.

#Machines for brewing tea also exist. These heat the water until the boiling point in a container and the generated vapor passes into a steeping vessel, in which the tea is contained in a permeable capsule. This mode of tea preparation differs from the classical mode of preparation because the brewing time of the tea is limited and the tea is discharged directly into a beverage container.

#This automatic preparation often doesn't correspond to the “classical mode of tea preparation” as the tea is left only a limited amount of time for brewing or steeping. Thereby a loss of taste results. Too much electrical energy is consumed unnecessarily due to the fact that all machines which contain a heater or are disposed to heat a predetermined amount of water in the shortest possible time contain a heating element which is continuously maintained at an elevated temperature to minimize the temperature difference between the initial temperature and the required final temperature of the water. The permanent tempering of the heating element results in the consumption of an unnecessarily high standby current. The known tea brewing devices are configured such that the user has to be physically present to operate the device directly.

#The machine is shown in an advantageous configuration in the drawings and is described and explained in detail in the subsequent description.

#It is shown in:

#FIG. 1: a sectional view through the interior of the machine showing all required components;

#The machine is shown in FIG. 1 in a sectional view. The housing 14 of the machine can have variable design or material depending on the production series. The housing 14 comprises a control panel 7, consisting of a touch screen or conventional rotary switches or knobs, by which the user can choose the desired preparation routine. The control panel 7 shows the user the required parameters for the infusing process, the process for the preparation of tea, also referred to as the preparation routine. Default values are registered for any parameters which the user can set or program according to his taste. These include: the required amount of water, the infusion temperature of the water and the infusion time or preparation time or brewing time. The machine includes a programmable and storable control unit 11 containing a microchip, which controls and supervises all processes. The user has the following possibilities to choose his settings:

#1. directly on the machine by means of the control panel 7,

#2. by means of his smart phone or a suitable application software or by means of a computer, which connects via a radio connection with the machine or by means of the antenna 9 belonging to the machine.
