coffee grinder

Coffee grinders are already known which have an input hopper, a grinding chamber connected to this input hopper, a motor that has an in
the hollow chamber arranged knife drives, a
have a collecting room for the ground coffee that is in communication with the clearing chamber and a sieve which is arranged between the grinding chamber and the collecting chamber and at least partially forms a wall of the grinding chamber. It is also known to provide the possibility in such coffee grinders that the sieve can be exchanged for other sieves that are supplied as accessories when the coffee grinder is purchased.

From / Pe

The aim of the innovation is to create a coffee grinder that offers the same possibilities, ■ 'e ^ .och k «? Lpsn sentence possesses accessories that are only annoying for the user, can be damaged or at the time cannot be found during use. The innovation is characterized in that the sieve has several parts, the size of which is approximately equal to the connection cross-section between the grinding chamber and the collecting space is, and that this sieve slides in a guide track that the connecting cross-section between the grinding chamber and traverses the collecting space.

Further details of the innovation emerge from the following description of an exemplary embodiment »where reference is made to the accompanying drawing. Show it:

Fig. 1 and 2 two vertical sections through a coffee grinder according to the innovation and

3 shows a modification of a detail.

Figures 1 and 2 show in section a cuboid Housing, in the upper part of which an input funnel 1, which is accessible through an upper opening 2, is provided is. Under this input hopper 1 there is a chamber for a motor 3, the * .7elle 4 of which is arranged horizontally is. The shaft 4 traverses a socket 5 provided in the bottom of the input hopper 1 and enters a Milling chamber 6 off. At the end of the shaft 4, a knife 7 is provided, which is arranged in the grinding chamber 6. the

Mahlkaramer 6 is connected to a collecting space in which a container, for example an insert 8, is arranged.

The walls of the grinding chamber consist of a cylindrical screen 9 cut along two surface lines, in the upper part and from a sieve 10 in the lower part. The sieve 10 has the shape of a circular cylindrical surface and surrounds the screen 9. This screen is attached to a disc 11, which has an operating button is provided. The disc 11 forms one of the vertical walls of the grinding chamber, the other being vertical Wall of the grinding chamber consists of a wall IA- delimiting the input hopper 1. This wall 14 has a circular opening 15 »in which a blade rotates, which regulates the flow rate of the Entrance hopper 1 allowed coffee beans entering the grinding chamber 6.

In the embodiment shown, the screen 10 consists of three separate parts 17, 18 and 19, which are connected to one another by clamping rails 20.

Each part 17, 18 and 19 consists, for example, of a metal fabric with a certain mesh size, with one a coarse powder, the other a medium powder, and the third a fine powder. the Disc 11 which is attached to one of the lateral ends of the parts 17, 18 and 19 of the screen 10, and the opposite lateral ends of the parts 17, 18 and 19 can slide in guide tracks 21 and 22, respectively.

The user can thus by turning the control button 12 the appropriate part 17, 18 or 19 of the sieve 10 choose between the grinding chamber 6 and the collecting chamber is to be used.

In the embodiment shown, a screen is used which is concentric to the shaft k , but is arranged eccentrically to the axis of the disk 11. The advantage of this screen 9 is that it prevents the coffee powder from backing up behind the unused parts of the sieve 10, in the present case behind the parts 10 and 10, because it is: -r coffee powder residue on the D.'uirr r ^; üi; · i ■■ we ·· ¹ u; id dirty the fresh powder- if mt t p. r. ■ <!:. · rh a thorough cleaning νοιτ. <· π "π: Γ / <· η \ ■ ι>'.

A slide 24 can move along the wall 14, with which the supply of non-ground coffee beans interrupted in the kahlkammer 6 v / can ground. This slide 24 closes the opening in the wall 14. It can also operate an electrical breaker in the fully closed position to be used. This interrupter can be provided, for example, at the point 25 that the slide after the circular opening in the wall 14 has been completely closed.

The shaft 4 can also be arranged in another way, for example vertically, instead of horizontally, at the same time making the other changes that this entails.
