DESCRIPTION

Individual coffee maker with integrated cup.

Object of the invention

The present invention relates to an individual coffee maker with integrated cup, which optimizes the use of energy and allows the brewing of coffee in the same cup, as well as the visualization of the process, thanks to the transparency of the cup itself.

Background of the invention

A wide variety of coffee makers are known for the preparation of coffee. Among the most popular are Italian type coffee makers. These coffee makers are economical, easy to manufacture and easy to use.

The Italian or Moca coffee machines generally comprise a lower tank with a threaded upper mouth, a coffee-holder filter attachable inside said mouth and a upper body with a threaded lower extension of coupling to the tank mouth and a central duct of coffee passage made up to a superior reception reception of the coffee made.

The main problem presented by these coffee makers is that the inside of the tank and the upper body is difficult to access, especially the deposit, since it usually has the mouthpiece narrower than the bottom and the hand cannot be reached comfortably to clean it . In addition, being the diameter of the base of reduced size, there is a waste of energy when applying the coffee maker in the non-induction hobs.

Description of the invention

The coffee maker object of this invention has as its purpose both to solve the problems existing in the current Italian coffee maker, and to improve certain common aspects of the coffee machines on the market and to add certain innovations that make the product more attractive. All this, of course, to increase the quality of life of consumers, at the scale that the aforementioned product can do.

The present invention solves the problem of waste of heat and facilitates the cleaning of the base. In addition to the aforementioned optimization of energy, which gives the coffee maker both the ecological advantage and time savings, it provides it with other significant characteristics that distinguish it from existing coffee makers.

Said coffee maker allows the visualization of the coffee brewing process through a transparent cup, which is an active part of the process and that acts as both a container and a mechanism, lightening and simplifying the process. On the one hand, it reduces the number of necessary parts, since the cup is a direct container of the coffee, avoiding an intermediate part to house the freshly brewed coffee, which makes it more comfortable and eliminates a part at the time of cleaning. And on the other hand, it makes the design of the coffee maker much more attractive, both for the forms and for the interest that the user raises the possibility of observing the brewing of the coffee through the duct that throws it into the cup.

An individual coffee maker, small and manageable, is proposed for ceramic, induction, gas or electric cooking, which allows producing a good quality coffee in the minimum possible time and respecting the environment as much as possible. These last two characteristics are achieved by making a larger diameter base to take full advantage of the heat energy emitted by the ceramic hob and thus avoiding! the waste of energy due to a too small base, which can even give problems when the sensor, in the case of the induction cooker, recognizes it because of its small weight and dimensions. In addition, prolonged contact of the coffee with hot water dilutes the flavor and extracts unwanted oils and other bad substances from the coffee, so, by carrying out the process faster, this is avoided.

On the other hand, the fact that the coffee is made directly in the cup for individual use, does not make excess coffee, but that fresh coffee is prepared every time it is consumed, which favors the quality of the coffee, which should not be heated because heat and air quickly cause unpleasant flavors and aromas.

It is also pursued, taking into account the market sector to which it is addressed and the situations of use, a minimization of the price, which is achieved using a simple design, without many components and a traditional but very valid mechanism.

This mechanism is used in the traditional mocha or Italian coffee maker, whose effectiveness has been corroborated for years.

Another feature of great importance in the design is the transparency of the cup, which allows the user to see when the coffee is finished, without forgetting the great aesthetic appeal that this implies, together with the spherical and rounded shapes, the simplicity of the product and the combination of textures that form steel and Pyrex.

It should not be forgotten either, the fact of the excess capacity of the cup with respect to the water cavity, this is necessary since it is desired that the user can drink the coffee directly from the container that contains and brews it and that means that he can put the supplements you want in it, that is, you can put milk, ice, etc. in the cup. This coffee maker has some marks in the base that correspond to those arranged in the cup and allow the user to know, in an intuitive way, the amount of coffee that will be obtained depending on the amount of water that is poured into the base.

Preferred Embodiment of the Invention

Below is a preferred embodiment of the invention that is not limiting in scope.

As can be seen in the referenced figures, the coffee maker is made up of seven basic parts and some optional additional parts (lid-coasters and lid-portable).

The fundamental parts are: Base (1), Base-filter (2), Cup (3), Flat filter (4), Pressure relief valve (5), Rubber ring (6) and Filter (7).

Next, the elements that make up the projected coffee maker will be briefly described and detailed.

Base (1):

It is used to contain water, it is made of 2 mm thick stainless steel and is the one that maintains direct contact with the heat source. It is a cylindrical piece with an external diameter of 116 mm and height 42 mm, open at the top to facilitate filling and cleaning.

In addition, it has an external thread at the top that allows its union with the second part of the coffee maker: the base-filter, whose inner diameter is also approximately 116 mm, since it has an internal thread for perfect coupling with the base .

Inside this element are distinguished punched marks, which serve as gluttony for the preparation of the different types of coffee (according to the quantity), corresponding the number of brands with those made in the cup, to know intuitively how far It will be filled. This piece will withstand the highest pressures, which will be relieved by the valve located in the base-filter.

The contact with the hob or other energy source will be 110 mm, subtracting from the outside diameter the 3 mm rounding radius made and this contact being even higher than that of any coffee maker, and optimizing, therefore, the use of energy .

The weight of the base is 0.39 kg and its internal capacity is 393 cm3 or 393 ml, although the ideal volume of water to be used to make a good coffee is 225 ml.

The stainless steel chosen is the AISI 304.

Base-filter (2):

It is called asl because it is the part that incorporates the funnel-shaped filter that houses the coffee and through which the water that evaporates, raises and passes the ground coffee taking its properties, such as aroma, flavor and color. As we have indicated previously, this piece is threaded to the base by means of an internal thread.

The base-filter is also carried out in stainless steel (2 mm thick), for a correct union of the parts and for the technical requirements of the process, such as withstanding high temperatures and corrosion due to contact with water.

It should be added that it has a general cylindrical shape, but it also has a protrusion on the upper face for hooking and correct fastening of the cup during brew preparation. The general dimensions in which the piece is cubed are: diameter 120 mm and height 52 mm (of which 9 mm correspond to the height of the projection that covers half of the piece and whose dimensions coincide with the groove made in the cup for its attachment to this piece during the preparation of coffee, also serves as a stop to center the cup with the funnel containing coffee powder).

The filter, contained in the cylinder, has a height of 15 mm, its diameter being 60 mm greater (coinciding with the hole in the base of the cup, for coupling) and its diameter smaller 8 mm. The thickness of the filter is 1 mm in the lower tube and 2 mm in the rest.

This element will be made with the process of casting molding and the subsequent internal threading for coupling with the base.

This piece has a weight of 0.57 kg. In addition, an M5 thread hole is made for the pressure relief valve.

The base filter needs an operation during assembly to fix the flat filter, which will be explained below. This operation is none other than pressing with a manual eccentric press, the part of the funnel to permanently fit the flat filter into it.

The material in which this piece is manufactured is the same stainless steel as the base, the AISI 304.

Flat filter (4):

It is coupled to the base-filter fitted by the indicated pressing operation.

It has a diameter of 60mm and a thickness of 1mm. Due to the impossibility of buying in the market separately from the standard funnel and it is also made of stainless steel AISI 304.

This filter weighs 19 gr.

Cup (3):

It is the most innovative part of the product, since it allows the visualization of the coffee brewing process thanks to its transparency. The material used is borosilicate glass, better known as Pyrex, whose resistance to high temperatures is very high, so it is commonly used in kitchen products.

The cup performs the function of passage of gaseous state to liquid of the coffee vapor, through the tube that leads it directly into the container from which it is drunk.

It is only necessary to extract or unhook the cup from the base-filter and add sugar, milk, cinnamon or the desired complement.

Also add a handle for your grip, whose material is the same as the rest of the cup and does not cause burns from heat transmission, since it does not reach high temperatures. The corresponding ergonomic studies have been made to the handle for the best manipulation and use of the cup.

As a safety measure, the upper part of the cup is not completely symmetrical as far as the circumference is concerned, but it has a projection in the area immediately above the outlet hole of the coffee, to avoid splashes that can be caused by the Pressure.

As already mentioned, the cup has some marks that indicate the level of coffee that can be obtained depending on the filling of the base and also, a top mark of filling the cup so that it does not overflow or have spillage problems through the hole through which the coffee comes out.

The cup has a slot that fits the base-filter, as mentioned above. This slot extends around the entire cup to facilitate its coupling in the base without limiting it to a specific area.

The coffee outlet hole is strategically placed in the handle line, to avoid the spillage of coffee through it, since the inclination of the liquid that occurs when drinking does not cause its spillage, being the natural position to drink, of the side or front edge of the cup. To this is added that it is of reduced dimensions and is placed on the top of the cup and above the top line of filling of the same, which also avoids the pouring of the waves produced by moving the cup from a place to other.

The general dimensions of the cup are: 120 mm high, minimum thickness 3 mm and 108 mm the largest diameter, the smallest being the one corresponding to the base and 66 mm.

The weight of the cup is 0.75 gr.

The commercial parts are described below:

The coffee maker needs two pieces that are attached to the bottom hole of the cup. These parts are a filter (7) and a rubber ring (6) that serves to attach the filter to the cup without the need for any adhesive or other joining method that makes it difficult to assemble in the production and clean it during the use of the product.

The metal filter has an upper diameter of 60mm and a lower diameter of 50mm coinciding with those of the rubber ring, for perfect coupling. However, the inside diameter of the rubber is slightly less than 50, since it is fitted by stretching the rubber, which will return to its place and will be fixed to the filter when released. The larger diameter, slightly greater than 60, is also equal to that of the bottom hole of the cup, to allow both parts to be embedded in the same made thanks to the elastic characteristics of the rubber. These parts can be disassembled when required for washing.

The height is 5 mm in the case of the filter and 4 mm in that of the rubber, since the filter has the upper diameter of 60 that has a height of 1 mm and places the rubber so that it does not exceed it.

The function of the filter is to prevent coffee grounds from passing through, only passing the liquid coffee that rises from the base-filter (whose solid funnel container is also 60 mm in diameter, as already mentioned).

The materials of these pieces are rubber for the ring and aluminum for the filter.

Pressure and temperature relief valve (5):

Its mission is to release the fluid when the pressure / temperature exceeds an established limit or threshold, to avoid an explosion. It is a safety measure in case the filter is clogged.

Its height is equal to the thickness of the base-filter where it is threaded, that is, 3 mm and is an M5 thread.

This piece is made of brass.
