During the Brewing time creates a concentrated brew. After the selectable drawing time a second amount of hot water is poured over the resulting brew. This hot water runs into the drawing and filter insert. Here the brew vigorously mixed together with the brewed product so that the  Ingredients such as caffeine, complexion, aroma and tannins from the brewed goods are very good be washed out. This is parallel or slightly delayed Exhaust valve electrically controlled and opened. The hot water supply is designed so that it corresponds to the outflowing amount of the infusion beverage or at least approximately. This ensures that during the total pouring time of the liquid level in the drawing and filter insert remains about constant. This measure supports intensive mixing of the brewed goods and the complete washing out of the ingredients. That done processed infusion drink then flows into a receptacle in the Usually a thermos flask. The outlet valve is expedient timed. The time control can be directly or indirectly dependent be poured with the pouring of the second hot amount of water.

A spring-loaded outlet valve is arranged below the outlet valve. In a preferred embodiment, this is a so-called Drip-stop valve, which is set by adjusting the receptacle from the Closing position is shifted to the open position.

The pull and filter insert is funnel-shaped, the Outlet valve at the bottom of a cup-shaped substructure of the drawing and filter insert is arranged. The base part is expedient removable from the pulling and filter insert. This measure facilitates the Cleaning.

The device used in the context of the invention stands out first of all through its technically and structurally simple structure and Handling off. Furthermore, the compact design with less Stand out height, since only a subset of the Water is added to the drawing and filter insert. The brew preparation and the infusion beverage is filtered in just one container. This can the overall height can be reduced compared to the prior art.  

According to the invention, the brewed product is first used in a drawing and filter insert poured a first amount of hot water. This mixture can then through so that a concentrated brew is produced. The brewing time is can be predetermined and is made using conventional, in particular electronic Automatic timer controlled. The resulting brew is then after a predetermined time mixed with a second amount of hot water, in front of the infusion drink from the drawing and filter insert into one Receiving container is transferred.

In this way, a high-quality infusion drink is produced. Both when applying the first amount of water and when supplying the second quantity of water is mixed vigorously. The content and aromas are washed out intensively. The aroma and the quality the resulting infusion drink is intense and substantial.

The invention is based on one in the accompanying drawing Described embodiment described in detail, which invented In accordance with the electrically operated household appliance for preparing hot infusion drinks, especially tea or coffee, in the front view shows.  

The household appliance is generally designated 1. The illustration is part technically simplified. Taxes and rules are not shown directions including automatic timer and also the electrical supply.

The household appliance 1 has a device housing 2 , in which the aforementioned switching and control devices are housed. The device housing 2 can be made of plastic, but also of stainless steel. Affixed to the device housing 2 is a foot part 3 on which a collecting container in the form of a thermos 4 can be placed. A warming heater 5 can be accommodated in the foot part 3 .

Fresh water is in a water tank 6 of the device housing 2 before guessing. From this, the water can be drawn off via a bottom outlet 7 by means of a pump 8 . It then passes through a curved pipe section 9 to a heating device 10 . Hot water of the desired temperature is generated in the heating device 10 and is fed from there to a brewing system 12 via a feed line 11 . In the supply line 11 , a valve is incorporated, which only opens the supply line 11 for the flow when the water is heated to the desired hot temperature.

The brewing system 12 comprises a drawing and filter insert 13 with an outlet valve 14 on the bottom. The outlet valve 14 can be controlled electrically or electronically. For this purpose, a, with the control and switching device of the device in electrically conductive connection, contact unit 15 is provided between the outlet valve 14 and the switching and control device. In practice, an electrical outlet valve 14 comes in the operating position of the household appliance 1 with the contact unit 15 in electrically conductive contact when adjusting the pulling and filtering insert 13 . In the case of an electromechanical outlet valve 14 , this is controlled electrically and the sealing body of the outlet valve 14 is opened mechanically, for example by a lever or slide.

The pull and filter insert 13 is funnel-shaped. At its bottom 16 , a cup-shaped substructure 17 is arranged. This is detachably coupled to the drawing and filter insert 13 and comprises with its edge 18 a pot-like depression 19 on the bottom 16 of the drawing and filter insert 13th

An outlet valve 20 is arranged in the bottom 19 of the base component 17 below the outlet valve 14 . The outlet valve 20 is a conventional spring-loaded drip-stop valve. The spring of the drip-stop valve 20 is designated 21. By adjusting the thermos 4 , the valve body 22 of the drip-stop valve 20 with its sealing ring 23 is raised and the passage 24 is released in the base part 17 .

For the preparation of tea or coffee, the brewed material is filled into a paper filter bag and placed in the drawing and filter insert 13 . The brewed product is then poured with a first predeterminable amount of hot water and draws a correspondingly selectable time, so that a concentrated brew is formed. After the desired brewing time has elapsed, a second amount of hot water is poured over the resulting brew. Here, the brew, together with the brewed goods, is mixed vigorously. As a result, the ingredients are washed out of the brewing material very intensively. The outlet valve 14 is opened electrically in parallel or with a slight delay.

It clears the passage 29 , so that the ready-made hot infusion can flow into the thermos 4 via the outlet valve 20 . The passage 29 or its opening cross section are designed such that the amount of finished infusion beverage that flows out corresponds to that of the incoming amount of hot water. The liquid level in the drawing and filter insert 13 remains approximately constant. This measure supports the brewing process or the mixing of the brewed goods. You get a very aromatic, tasty infusion drink.

In practice, it may be appropriate that the brewing process is made dependent on the fact that the thermos 4 is set in the device 1 . This can be done by means of suitable contact or optical sensors.
