Description

Embodiment of the invention. The coffee machine has a lower part 1 and an upper part 2 which are detachably connected to one another. The upper part 2 is designed as a unit consisting of a filter 3, a water tank 4, a riser upper part 5, a brewing water outlet 6 and a water tank outlet 7. The lower part 1 consists of a base 8 and a handle part 9 arranged thereon. In a recess in the base 8, a holding plate 10 for a coffee pot 11 is provided. A water heater 12 is arranged within the base 8 in direct thermal contact with the hotplate 10. The flow heater 12 is connected to the water tank 4 via a cold water fall line 13 and to the brewing water outlet 6 via a riser pipe lower part 14 and a riser pipe upper part S. The brewing water outlet 6 is arranged above the filter 3. The riser pipe lower part 14 and the cold water pipe 13 run inside the handle film 9 and end in the upper end of the handle part, the riser pipe lower part 14 reaching into an overflow channel 15, the opening 16 of which is arranged above the coffee pot 11. An insertion opening 17 for the upper riser part 5 is provided in the upper part of the handle, concentric with the lower riser pipe part 14. The plug-in opening 17 is automatically closed by a closing device 18 when the upper part 2 is lifted off, so that after the brewing process has ended, water vapor still escaping from the lower riser pipe part 14 or any residual water in the cold water fall line 13 is passed through the overflow channel 15 and the coffee pot 11. The water tank outlet 7 is automatically opened and closed by a valve, not shown. To initiate a brewing process, the upper part 2 is filled with the water tank 4 and the coffee menu

ίο placed in the filter 3 on the coffee pot 11. With this one Operation is the closing device 18 through the riser upper part 5 against the force of a Spring 19 is pivoted about a bolt 20 and the insertion opening 17 is released. The swivel movement

The movement of the locking device 18 is initiated by a bevel 21 on the locking device 18 and a centering device 22 on the handle part. When the upper part λ is placed on the coffee pot 11, the upper ascending pipe part 5 with the lower ascending pipe

ao part 14 and the Kaltwasserfalieitung 13 with demι water tank outlet 7 releasably connected. For sealing between the riser lower part 14 and the riser upper part 5 a seal 23 is provided.

Fig. 7 shows a further embodiment of the

Invention, wherein the coffee pot base 24 is formed by the water heater 12 and the Coffee pot jacket 25 is interchangeable.

1 2 can be closed by a closing device, claims: that in the separated state the lower part of the riser pipe and the coffee pot are connected to one another through an overflow channel 1. Hiterkoffeemaker, primarily for the connected and that the water heater with Domestic use, consisting of a filter and water 5 connected to the bottom of the coffee pot, is expedient container, riser pipe, cold water downpipe, coffee is the closing device by means of a can and at the same time arranged as a tub holding plate upper end of the riser pipe lower part trained electric water heater, there- actuated centering device. After another characterized in that the riser embodiment of the invention is the Steigronrim upper coffee pot area is divided that ίο lower part together with the cold water fall line in the insertion opening (17) arranged for the upper riser handle part of the lower part. (S) and the water tank outlet (7) through a. This achieves that the inventive Closing device (18) can be closed, household coffee machine after the end of the brewing process in the separated state riser pipe lower part (14) process can be used as a warming device and coffee pot (11) through an overflow channel 15. To fill the water tank, the (15) are interconnected and that the coffee machine parts, filters, which form a unit The water heater (12) with the coffee pot and water container, removed and the water base (24) is connected. container with the required amount of water 2. Filtei coffee machine according to claim 1, that the water pipe is filled. After filling with the coffee through in that the Verschließvorrich- ao flour in the filter the coffee machine upper direction (18) is set by means of a part on the upper end back on the bottom part. In the process, the lower part (14) of the ascending pipe opens automatically the water tank outlet and the leveling device (22) which can be actuated. early the insertion opening for the upper part of the riser pipe. 3. Filter coffee machine according to claim 1 After completion of the brewing process can or 2, characterized in that the riser »5 upper part can be removed again, with the the lower pipe part (14) automatically closes again together with the cold water tank outlet downpipe (13) in the handle part (9) of the lower part (1) and at the same time the insertion opening for the riser is. The upper part of the pipe is closed. Occurring water steam or in the cold water downpipe ; io Residual water and possible condensate cannot enter the The invention relates to a filter coffee machine, get free atmosphere, but it is about the primarily for household use, the filter, overflow according to the invention into the coffee pot geWater container, Riser pipe, cold water downpipe, Kaf pipe, which scalds or the like of the Befeekanne and one at the same time as a hot plate 35 users are excluded. In disassembled electric water heater. In this state, the water heater is only used Electrically heated filter coffee machines are used as hot plates for the coffee pot. Through the known in the most varied of embodiments. The hotplate is used to cool the coffee can prevent this known filter coffee machine. It is particularly advantageous if the Two different basic designs under the * o coffee pot base at the same time by dividing them through. In one embodiment, water heaters are formed. This is the direct The container and the coffee pot are arranged side by side. Contact between the hotplate and the one in the net. With this type of machine, the continuous jug ensures that there is coffee in the machine. About it heater at the same time as a hot plate for the addition, z. B. the jug jacket slightly out of the coffee pot serve. The heated water will change in the 45. It appears to be a particularly advantageous riser pipe raised and flows over a filter in stick when a glass jug jacket is used. As the coffee pot. To serve the coffee, the glass jug jacket and the water heater must be included The jug can be removed from the hotplate and can be connected to another part of the stand will. In the other embodiment, water technology is used and does not need to be explained in more detail here containers, filters, water heaters and coffee;> o to become. can arranged one above the other.
