Description

UHT Umwelt- und Hygienetechnik GmbH., Vogelruth 15, H800 Bielefeld Electric coffee maker The invention relates to an electric coffee f

machine with an electric% that can be filled with fresh water

heated cooking chamber with hot water running ", arranged under the \ cooking chamber and a filter cup under this
intended receptacle »preferably jug *

Such coffee machines are available in a wide variety of

tours become known. With these coffee machines, |

the heated water continuously in the form of drops or as J

r a thin stream of ground coffee so that the \

constant water supply, the coffee grounds are heavily washed out ' _:

(leached out) and thereby not only the aromas but also ■

other substances, such as acid and bitter substances, from the coffee {

flour be given what the flavor taste of fil- \ th coffee impaired *

The object of the invention is therefore to avoid the
the aforementioned shortcomings to create a coffee machine that has a special hot water supply to the coffee grounds, whereby
while improving the taste of the filtered coffee
from the ground coffee mainly the aromas and not "so much
taste-changing substances are released.

This "task" is "solved according to the invention" by the hot water outflow from at least one setting and controllable in at least two stages one after the other, »first a small amount of hot water to swell of the ground coffee and then the remaining amount of hot water for brewing the coffee with a time interval is formed continuously or taktweiae dispensing nozzle.

O are advantageous further training courses for this task solution from the subclaims * The subject matter of the invention extends not only to the features of individual claims »but also on their combination ·

The coffee machine according to the invention works in an advantageous manner In two stages, namely in a first infusion stage, in which a small amount of hot water is added to the coffee grounds is added to swell, and in a second infusion stage »which starts automatically after the swelling time» and in which the remaining hot water is poured in one continuous infusion or in a few successive infusions / pour the finished brewing of the coffee into the filter. | Furthermore, the fresh water in the cooking space is up to Boiling heated so that at least in the first infusion stage boiling water is added to the coffee grounds Swelling process favorably influenced »

Through this two-stage process, the ground coffee gives off the aromatic substances and only a small amount of acid and bitter substances » thereby a substantial Gesohmaoks improvement is achieved with filter coffee.

This automatically operating coffee provides a filter coffee forth "like him would prepare the housewife manually _t namely Que ^ llaufguß and then remaining Endaufguß" can be brewed whereby the rich taste of coffee first, "

/ λ This type of coffee production means better utilization of the coffee aroma guaranteed.

The coffee machine is easy and cost-saving to set up

builds and demonstrates trouble-free, automatic work

Based on the drawing, the following details are given in the following: "· games according to the invention explained in more detail. It shows?

Fig, 1 is a schematic representation of a coffee * » machine with a hot water spout nozzle and Spray filter j

q Fig. 2 is a schematic representation of a coffee scheme

machine with two hot water nozzles and Inclined filter.

With 1 is an electrically heated one that can be filled with fresh water Cooking space of the electric according to the invention Coffee machine denotes »which is arranged in the upper area of a base body 2 that can be set up or hung up is »Below this room 1 there is a Removable filter cup (pot) 3, which can be inserted or attached to the floor of the cooking space in general or on the basic body 2 held detachably or on a receptacle 1, preferably jug, is detachably attached.

Since "cold fresh water in the cooking chamber 1 is formed by electrical heating elements 5, preferably above the cooking chamber floor la are provided to boiling (100 ⁰ C) for" Further, the cooking chamber 1 can be constructed as a water heater, internally also the cold fresh water to the boil is brought *

...
The cooking space 1 is at the bottom with at least one hot

^WM * water outlet »which is formed by an adjustable and controllable nozzle 6 that works in at least two stages one after the other» This nozzle 6 is first one

a small amount of hot water with which the ground coffee in the filter holder 7 of the filter cup 3 is calibrated 8 is swollen »so that this coffee grounds 8, as in FIGS. 1 and 2 in dash-dotted lines Lines 8a shown, pulls up on the filter side wall (swells up) and thus an enlarged infusion surface a offers

After a certain, set swelling time there is then the outlet nozzle 6 in its second stage the remaining amount of hot water for brewing the coffee from »what in a continuous or in a cycle Can be run out

If, for example, with the coffee according to the invention » machine ten cups of coffee should be brewed » so the first spout for swelling the ground coffee z. B. about the amount of water in a cup and the second spout then correspond to the remaining amount of water (nine cups)

During the first outlet to swell the ground coffee 8, the water must flow out of the outlet nozzle 6 ^{at a boiling point (at a temperature of 100 0 C)} Outflow temperature »which is slightly below the boiling point ·

As the embodiment of FIG. 1 shows, the Outlet nozzle 6 in the center (in the middle) of the Koohraumboden la arranged and this nozzle 6 is controlled so "that ei" which carries out two flood stages one after the other

According to the further exemplary embodiment according to FIG. 2, two outlet nozzles 6 are provided in the side areas of the Koahraumboden lie »Here one serves DUse 6 for the first outlet and the wide nozzle 6 for the second hot water outlet, while the first nozzle the amount of hot water to swell the ground coffee · releases » the second nozzle 6 remains closed · Only after the end of the up-jet offset does the white nozzle move 6 automatically to dispense the second hot water outlet and then the first nozzle 6 is closed

The arrangement of two outlet nozzles 6 results in another Improved spreading of the ground coffee when swelling, since the hot water feeds alternately (each single) ι is also the one-sided hot water supply clocks the second lateral nozzle 6 contributes to perfect coffee brewing

It goes without saying that it is within the scope of the invention of two nozzles 6 auto use several nozzles 6 and their arrangement in the center and also off-center in the cooking space floor la *

The filter collector 3 can be used as an inclined filter (see Fig. 2} » the a cheap pulling up of the coffee grounds on the long one inclined side results in »or designed as a cone filter (see Fig. 1) and two types of filter is the arrangement of one» two or more nozzles possible·

It is preferred »in the kitchen room 1 a water softener 9» preferably to arrange an ion exchanger (see Fig. 2) which converts the kitchen space 1 into an upper hairdressing water

holder and in the actual Koiahram, the one below of the softener 9 is divided! here fresh water flows down through the food hardener 9 through

Any jug (glass or ceramic jug) or a warm jug can be used as the coffee receptacle H provide. The base body 2 can also be provided with a (") Hot plate 2a be provided, which is fixed or removable
