BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention concerns an automatic ground matter dispenser having a reservoir comprising a bottom and a lateral wall, containing a quantity of ground matter and positioned in a seat of complementary shape produced in the top part of a casing, and at least one rotating blade positioned in the bottom of the reservoir, rotated by a motor unit housed in the casing, and suitable, when it turns, for transferring through an outflow opening formed in the reservoir a given quantity of ground matter to an outlet produced in the seat of the casing and communicating with the opening in the reservoir.
BACKGROUND OF THE INVENTION
In known dispensers of this type, notably but not exclusively mounted on automatic coffee machines, the reservoir containing the ground matter is positioned non-removably in the seat of the casing, which forms an integral part of the machine. Such a dispenser with a non-removable reservoir is able to be used with different types of ground matter, that is to say ground matter with different particle sizes, of the same product in powder form, but without it being possible for the user to change the type of ground matter as he pleases whilst the reservoir is not empty, which makes it a dispenser the use of which is particularly limiting for any user wishing to change the type of ground matter.
The invention aims notably to overcome this drawback and to produce an automatic ground matter dispenser which enables the user to change when desired the type of ground matter of the same product in powder form even before the reservoir is empty, and this in a simple and efficacious manner.
SUMMARY OF THE INVENTION
According to the invention, an automatic ground matter dispenser of the type disclosed above is more particularly characterised in that the reservoir is removably mounted in the seat of the casing by means of at least two separable rotating mutual coupling devices which are arranged respectively in the bottom of the reservoir and in the bottom of the seat of the casing, and which are coupled in rotation respectively to the blade and to the motor unit, the reservoir also comprising means adapted, on the one hand, to close off the opening in the reservoir when the motor unit is stopped, and on the other hand to free this opening when the motor unit is started up.
By means of this embodiment, it will be understood that the user can, at any time, remove the reservoir already in place which does not contain the type of ground matter required, and fit another identical reservoir in its place which contains the type of ground matter required. Furthermore, the fitting and removal of the reservoir are particularly easy, which helps to produce a dispenser which is convenient to use for the user.
BRIEF DESCRIPTION OF THE DRAWINGS
The characteristics and advantages of the invention will, moreover, emerge from the description that follows of a particular embodiment taken by way of non-limitative example and illustrated in the accompanying drawings, in which:
FIG. 1 is a view in vertical cross section of an automatic ground matter dispenser according to the invention, showing a ground matter reservoir in the fitting position;
FIG. 2 is a view in cross section along the line II--II in FIG. 1;
FIG. 3 is a view in cross section along the line III--III in FIG. 1;
FIG. 4 is a view identical to FIG. 1, showing the ground matter reservoir in the removal position; and
FIG. 5 is a view identical to FIG. 4, to a smaller scale, illustrating three chosen reservoirs each containing a given type of ground matter.
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the automatic ground matter dispenser in accordance with the invention will be described in terms of the dispensing of ground coffee, it being understood that such a dispenser can also be used to dispense ground matter of any other kind, for example flour, without falling outside the scope of the invention.
In the example embodiment illustrated in FIG. 1, the ground matter dispenser 1 includes a reservoir 2 of cylindrica
