Description

Coffee making device having a foaming device [0001] The present invention relates to a coffee making apparatus capable of producing a beverage having a particularly dense and compact foam. [0002] As is known, the conventional coffee brewing device, which has been manufactured by the applicant since the early 1900s and is more commonly known as "mocha," is very common worldwide, and nearly 2 million units are still sold annually despite the success of alternative systems such as single-serve capsule systems. [0003] Users of coffee brewing devices generally like the aroma of the beverage obtained with this type of coffee brewing device (this aroma is very different from that obtainable with the alternative systems mentioned above). [0004] Nevertheless, there is no doubt that users understand any design that allows a beverage with a dense and compact foam to be obtained with a coffee making device, as is the case with some alternative systems. [0005] Evidence of this recognition consists of the efforts that coffee machine manufacturers have made and continue to make today to manufacture coffee machines that provide somewhat complex devices capable of producing a beverage with a dense and compact foam. [0006] Evidence of these efforts is provided by several patent documents disclosing embodiments of such devices, such as EP-A1-1813173, WO2008/087481, WO2016/113621, WO03/056986, WO03/055366, GB2436280. [0007] However, these devices often cannot guarantee that a beverage with a truly dense and compact foam will be obtained; furthermore, these devices are often particularly complex to manufacture and unsuitable for mass production. [0008] To overcome these disadvantages, the applicant has fine-tuned a coffee making device having a foaming device, and these features are the subject of the claims of international application WO-A1-2019/111074. [0009] In an attempt to expand the improvements, the applicant has fine-tuned the alternative foaming device claimed in the present invention to overcome the above disadvantages. [0010] Accordingly, the object of the present invention is to provide a coffee making device that ensures obtaining a beverage having a dense and compact foam while being manageable and easy to assemble, in an alternative way to the already known. [0011] This objective is achieved by the coffee making apparatus according to claim 1. Dependent claims describe additional advantageous embodiments. [0012] The features and advantages of the coffee making apparatus according to the present invention will become apparent from the following description, given as a non-limiting example in accordance with the accompanying drawings. - FIG. 1 illustrates a coffee making apparatus according to an embodiment of the present invention. - FIGS. 2A, 2B, and 2C illustrate a foaming device according to an embodiment of the present invention. - FIGS. 3a and 3b illustrate a valve of a foaming device according to an embodiment of the present invention. - FIGS. 4a to 4e illustrate plan views of the valves of FIGS. 3a and 3b. [0013] Referring to FIG. 1, the coffee making device (1) includes a boiler (2) which is preferably made of a single-piece container, which is generally made of steel or aluminum. [0014] The boiler (2) includes a bottom (4) intended to be placed on a cooking surface, such as a gas ring, hot plate, or induction surface. [0015] According to an embodiment, the boiler bottom (4) includes a plurality of inserts made of a ferromagnetic material, such as steel, if the boiler bottom is typically made of aluminum, allowing the coffee brewing device to be used on an induction surface. [0016] The boiler (2) further includes an annular boiler wall (6) that protrudes from the bottom (4) and terminates at the top with a boiler mouth (8) that is typically provided with a thread (10). [0017] The coffee making device (1) preferably includes a safety valve (12) inserted through the thickness of the boiler wall (6). [0018] For example, a safety valve is manufactured in accordance with the applicant’s document EP-A1-1797360, the contents of which are expressly incorporated herein. [0019] Accordingly, the boiler (2) has an internal boiler chamber (14) that is defined by the boiler bottom (4) and the boiler wall (6). [0020] The coffee making device (1) further includes a dosing device funnel (20) that can be housed in a boiler chamber (14), and the dosing device funnel is typically supported by the edge of a boiler mouth (8). [0021] The injection device funnel (20) includes an injection device conduit (22) for rising water from a boiler chamber (14), leading to an injection device compartment (24) intended to hold coffee powder. [0022] The injection device conduit (22) and the injection device compartment (24) are preferably separated by an injection device filter (26), which is typically composed of a perforated sheet, provided to prevent coffee powder from falling through the injection device conduit (22). [0023] The coffee
