DE3300287A1 - Automatic tea and coffee-brewing apparatus - Google Patents

Abstract

In order to automate the manual tea and coffee-brewing operation, the simplest solution seems to be three vessels mounted one above the other. However, this fails by the introduction of the tea or coffee into the central vessel. By our invention, the brewing container is accessible from above and can nevertheless easily be flooded with the aid of the principle of communicating pipes. In this case, the position of the upper vessels relative to one another in the horizontal plane is irrelevant. The brewing vessel can even be incorporated in the water-heating vessel. The beverage is made as follows: tea or coffee is introduced into the filter system and the latter is suspended in the brewing vessel, the water-heating vessel is filled with water, the brewing time preselected and the apparatus switched on. The following operation then proceeds automatically inside the apparatus: water is heated up to boiling, the water-heating vessel is connected to the brewing vessel, water flows into the brewing vessel, the brewing-time limiter runs from this point in time; when the brewing time has elapsed, the water-heating and brewing vessel is opened at the bottom, and hot residual water and concentrated tea or coffee drain into the serving container.

description

Tea and coffee maker

The invention is used for the automatic brewing of coffee or tea, in particular for private households.

The tea or coffee is to be matched automatically with boiling water and after a selected time of be separated from this again.

We are not aware of anything else from a fully automatic system that fulfills the stated purpose.

The invention is based on the object of making the important infusion time freely selectable, particularly when preparing tea.

The object is achieved according to the invention in that the machine is divided into three vessels. Two of them are above of the third and arranged by a pipe or hose underlay interconnected to form a system of communicating tubes.

An embodiment of the invention is shown in the drawing and is described in more detail below. she shows the two upper vessels, which are designed in a volume ratio of 4: 1 and are connected by a joist. There are two valves in this beam. Valve # 1 opens and closes the girder with respect to those above it Vessels. Valve no. 2 is at the lowest point of the beam and opens / closes it to the outside. Below Valve no. 2 is * the third vessel. The coffee or tea is poured into the smaller vessel within a filter system. Water is poured into the large upper vessel and brought to the boil. At this stage, both valves are still closed. When the water boils, valve no. 1 is activated and opens the beam. The small vessel is flooded by it, until the level of the water level has equalized. With

the control signal for valve # 1 becomes a variable timer set in motion, which forwards the signal to valve no. 2, shifted by a preselected time. This opens the girder to the outside and both upper vessel contents flow into the vessel below.

The advantages achieved with our invention are particular in the automation of the individual tea brewing process.
