Definitions
- the present invention relates to the field of the coffee machines, both for domestic use and professional use and in particular the field of the automatic or semiautomatic coffee machines.
- a coffee machine For producing coffee-based drinks semi-automatic or automatic machines are used with a high number of functions and controls. A high level of automation is applied also to the machines for domestic use and not only professional use.
- a coffee machine has a brewing unit, a water reservoir , a boiler for the production of hot water to supply to the brewing unit, a coffee container, an electronic control unit and a user interface.
- the user can set a series of functions, parameters for producing the drink and other, depending upon the machine model and the performances thereof. In some cases the machine produces exclusively coffee, whereas in others it can produce even other drinks, for example hot water, cappuccino, hot milk or the like. All these functions can be selected, if present, by means of the user interface.
- a reservoir of coffee beans and a grinder to grind the coffee beans and to produce a coffee powder which is supplied to the brewing unit.
- the reservoir receives directly the coffee powder and this is supplied in doses predetermined and set by the user to the brewing unit.
- the machine stops by providing an alarm signal to the user, which has to see to fill up again the coffee container.
- a volumetric system for measuring the powder produced by the grinder is provided. If the quantity of coffee powder required for one dose of drink is not reached in a pre-set grinding time, this is interpreted by the central unit of the machine as absence of coffee beans in the container. The machine stops and the user has to fill up the container with new coffee beans, starting again the machine. As the central unit knows the volume of ground coffee, in this case it is possible performing a second grinding operation to reach the volume of ground coffee necessary to obtain the cup of coffee.
- This system has two drawbacks. First of all it is necessary to adopt a system for measuring the quantity of ground coffee, which increases considerably the costs and the size of the machine. Secondly, the volumetric measurer is subjected to failures and thus it represents a critical element in the operation of the machine. Furthermore, when the coffee beans exhaust during the grinding phase, the machine stops and the user has to fill up again the container , when, on the contrary, one would expect to be able to obtain quickly a cup of drink. This makes not very comfortable the use of the machine. In order to avoid the stop of the machine during the grinding and brewing cycle, the user should control the level of the coffee beans in the container each time before starting the machine.
- the coffee volumetric measuring has been eliminated and a measured is performed, based upon the revolutions which the grinder has to make to produce the wished quantity of ground coffee, assuming that between the revolutions and the quantity of ground coffee there is a biunivocal relation, a sufficiently precise assumption for the requested goals.
- the grinder continues to rotate without coffee therefore without producing powder and the machine is stopped after a certain period of time.
- the stop is performed as a function of a signal indicative of the fact that the grinder is running unloaded.
- the central unit cannot recognize the already ground quantity of coffee and therefore it cannot know how much coffee should still be ground after the user has filled up again the container with beans.
- the control unit makes it necessary to unload completely the coffee powder produced in the cycle of partial grinding, which has remained incomplete in the phase preceding the stop, and the whole cycle has to be started again. This involves the clear drawback of wasting a partial coffee dose for each interruption due to the exhaustion of the beans in the container.
- the device does not operate and it does not send the signal of lack of coffee, even when the quantity of coffee in the container is insufficient for preparing one dose of drink.
- WO-A-2007/000195 describes an automatic coffee machine comprising a reservoir of water and a reservoir of coffee beans.
- the coffee beans are supplied to an underlying coffee grinder which produces the coffee powder with which the drink is produced.
- Predetermined doses of coffee powder are loaded into the brewing chamber for each brewing cycle.
- a capacitive sensor is associated to the reservoir of coffee beans, which sensor should be useful to signal to the user the presence of coffee beans and consequently the lack of beans, but it is not able to provide information useful for handling more correctly the content of the reservoir of coffee beans.
- the invention proposes to implement a coffee machine of the type mentioned above, which overcomes wholly or partially one or more drawbacks of the known machines.
- the machine according to the invention provides the use of a different type of detector or sensor for signalling, through the user interface, the need for restoring the quantity of coffee in the container.
- the senor is a sensor of capacitive type which allows sending a signal as a function of the quantity of coffee in the container.
- the sensor and the control unit of the machine are implemented, arranged and programmed to supply to the user information about the shortage of coffee in the container, to warn the user so that he/she takes action to restore an adequate level of coffee in the container.
- This piece of information is supplied advantageously when in the container there is still a quantity of coffee sufficient for preparing at least a predetermined quantity of drink, for example to supply one cup or two cups or even more cups of coffee.
- the sensor does not limit to warn the user that the container is empty , a circumstance that he/she can verify in any other suitable way and therefore it is not necessary adopting a proper sensor.
- the capacitive sensor is implemented and used in an innovative way: it allows the user to know that it is necessary to restore the right level of coffee (in beans or in powder) in the container, but such piece of information is supplied before exhausting the coffee in the container, so that the user can however perform at least one supply cycle. In this way the drawbacks described above of the most modern machines are avoided. In particular it is avoided that the user notices the lack of coffee in the container only when the container is wholly empty and in case one coffee supply cycle fails due to the lack of product.
- a coffee machine will be normally referred to wherein the coffee is inserted in beans and ground by a grinder, as this type of machines is more widespread than others wherein directly the ground powder is inserted , and as in these machines the need is more felt for detecting in a well-timed and reliable way the exhaustion of the coffee beans in order to intervene in the right moment and to provide for restoring the required quantity of coffee in the container.
- the invention advantages can be exploited even when the machine requests to be loaded with powder of ground coffee.
- At least a capacitive sensor can be associated to the container of coffee beans in a position so that this sensor can supply at least a signal of presence/absence of coffee in that position which corresponds to a threshold, therebelow there still is an adequate quantity of coffee to produce for example one, two or even more cups of coffee, but once reached this threshold it is necessary to signal to the user the possibility or need to fill up again the container with beans to avoid that in one of the subsequent cycles the machine stops.
- the interface can supply information about the quantity of coffee beans in the container in function of the sensor signal.
- This signal can be of optical type, for example a message on a display or a light signalling through one or more light-emitting diodes (LED) can be provided.
- LED light-emitting diodes
- the possibility of supplying a signal of acoustic type is not excluded, for example with sounding device or even with a speech synthesizer which communicates to the user the need for loading the coffee container.
- the senor can provide at least an electrically conductive strip placed onto the outer surface of the container, which develops for an adequate length in a direction corresponding to the direction along thereof the level of coffee beans inside the container lowers.
- an analog or digital signal which provides not only an alarm when the coffee goes below a minimum threshold or minimum level beyond thereof it is necessary to restore the quantity of coffee in the container, but even an indication about the really present level of coffee.
- Analogous results can be obtained by using a plurality of sensors arranged in sequence, each one thereof has a strip with smaller sizes, for a local or punctual detection of the coffee level by means of local measuring of the strip capacity. Each one of these sensors, then, will generally supply a signal of presence/absence of coffee. The combination of several signals provides discretized information about the real level of coffee in the container and not only an alarm signal when this level goes below a limit value.
- the measuring and therefore the signal generated by the sensor is based upon the fact that the capacity of the strip(s) or other measuring elements varies depending upon the presence or absence of coffee immediately near the measuring element. Therefore, by using measuring elements with proper shape and/or in variable number and position it is possible supplying to the user several types of information.
- a graph or a bar diagram is represented onto the interface, wherein each bar corresponds to one of the sensors arranged in sequence.
- the turning on/off of each light bar on the display or other interface allows the user to have an immediate and intuitive idea of the quantity of coffee existing in the container.
- a bar diagram on a display it is possible using a series of LED or other light indicators.
- the senor or the sensors can be of differential type, that is they can have two strips or other more or less extended measuring elements, manufactured with electrically conductive material, for example copper or the like, and arranged so as to generate two signals, the difference thereof allows obtaining a rejection of the common mode signals, caused by spurious factors.
- This is particularly useful to avoid, for example, that the signal is influenced by a humidity variation, or by a thermal shift or by the aging of the sensor circuit components or by other factors.
- figure 1 shows a schematic representation of the main components of an automatic coffee machine thereto a capacitive sensor is applied, for the detection of the quantity of coffee beans
- figure 2 shows a schematic representation of a sensor with an extended strip to provide an analog signal representative of the level of coffee beans in the container
- figure 3 shows a partial local section of a container thereto the sensor of figure 2 is applied
- figure 4 shows an enlargement of the detail designated with IV in figure 3
- figures 5 and 6 show schematic representations of other embodiments of the sensor.
- FIG 1 the main components of an automatic coffee machine, thereto the present invention can be applied, are represented under the form of functional blocks.
- the representation of the several blocks is schematic, as they are known to the person skilled in the art.
- the representation of figure 1 is to be meant exclusively as an example, as the invention can be implemented in machines of various type, even for example without the grinder unit, as indicated above.
- the machine designated as a whole with 1, includes a brewing unit 3, thereto, by means of a line 5, hot water under pressure is supplied.
- the water is picked up from a reservoir 7 through a pump 9 which makes the water picked up from the reservoir 7 to flow through a boiler 11.
- This is represented as boiler with instantaneous heating, that is wherein the cold water pumped from the pump 9 is heated during the boiler crossing. Therefore the boiler 11 can also be of other type, for example an accumulation boiler.
- more than one boiler and/or more than one brewing unit can be provided, for example for preparing coffee of different types, or even for the preparation of drinks different from the coffee.
- reservoirs of lyophilized or concentrated substances can be provided to supply to one or more mixers associated or combined to a brewing unit 3 for the production of coffee, the whole as known to the persons skilled in the art.
- a coffee container is designated with 13 which, in this embodiment example, is apt to receive coffee beans.
- the reservoir 13 has a lower output 15 therethrough the coffee beans are supplied to a grinder 17.
- the grinder can include, in a way known on itself, two grinding machines here schematically designated with 19A and 19B, at least one thereof can be controlled in the rotation for example by means of an engine 21.
- the coffee beans which are supplied from the reservoir 13 to the grinder 17 is ground and the coffee powder is supplied through a duct 23 towards the (not shown) brewing chamber contained in the brewing unit 3.
- the latter can be a brewing unit of any type and here schematically represented with a generic block, which has an outlet 25 therethrough the coffee-based drink is supplied, obtained by making the brewing chamber, wherein the ground coffee has been compressed, to be crossed by the hot water under pressure supplied through the line 5.
- the water pressure can be controlled and modified according to the type of drink which the user can obtain.
- control unit 27 can comprise a microprocessor or other programmable logic.
- control central unit 27 is connected to the brewing unit 3, to the boiler 11, to the pump 9, to the grinder 17 and to the engine thereof, in case to the water reservoir 7 an to a capacitive sensor 31 associated to the container 13 of coffee.
- the central unit 27 communicates towards outside through an interface schematically and generally designated with 33.
- This can have a display 33 A and one or more elements, components or devices, schematically designated with 33B such as for example LED, knobs, switches or other elements therewith the user can set functions or controls, that is therewith information about the machine operating conditions or other can be provided.
- the nature and the configuration of the interface 33 can be anyone and it is not particularly important. The important thing is that the central unit 27 through the interface 33 or other suitable component or communication element can provide the user at least a signal indicative of the quantity of coffee inside the container 13.
- This communication element can be inserted into the interface 33 or it could be also constituted by an additional interface separated by the main interface of the machine, wherein under interface any device, system, component or element is meant, which can provide intelligible information to the user under the form of light, acoustic, speech signal or other.
- the capacitive sensor 3 can be constituted by a punctual or local sensor, that is comprising a single strip or other electrically conductive measuring element, even if with small surface size, positioned at a height of the container 13 corresponding to the level below thereof it is considered to be necessary to fill up again the coffee container 13 to avoid that the machine and in particular the grinder 17 runs unloaded.
- the level thereat such type of simplified sensor can be positioned will be so that the volume of coffee beans below the level signalled by this sensor is still so as to allow preparing, for example, at least a small cup of coffee.
- the capacitive sensor(s) associated to the container 13 allow supplying a more processed signal which, apart from indicating the need for filling up again the container 13 when the coffee goes below a minimum level, can also provide an indication about the real quantity of coffee contained in the container itself.
- Figures 2, 3 and 4 show a possible shape of an analog sensor able to provide a piece of information of this type.
- the reservoir 13 is shown partially sectioned with a wall 13A outside thereof a sensor, wholly designated with 31, is applied.
- the wall 13A of the container 13 in this case is made of an electrically non-conductive material to allow the capacitive detection of the quantity of coffee inside thereof by arranging the sensor outside.
- the application of the sensor 31 outside the container is preferred, although the possibility of inserting the sensor inside the container itself is not excluded. Moreover, the last solution makes the sensor subjected to get dirty or to damage due to the continuous passage of coffee beans on the surface thereof. In other embodiments the sensor can be incorporated in the material forming the wall of the container 13.
- the sensor 31 has a supporting laminar element 31A for example made of vetronite, or other insulating material, onto the two opposed faces thereof two electrically conductive strips 3 IB and 31C are applied. These can be implemented by means of a usual technique for producing the printed circuits. As it can be seen in figure 2, each strip (in figure
- each strip 3 IB, 31C has an elongated shape in a direction corresponding to the direction F (figure 3), along thereof the mass of coffee beans moves gradually as they are supplied to the underlying grinder 17.
- each strip 3 IB, 31C has a longitudinal development in the direction of lowering of the level of beans inside the container 13.
- the electric capacity of each strip and in particular of the strip 3 IB faced towards the wall 13A of the container 13 varies gradually as the level L (figure 3) of the coffee beans in the container 13 lowers, circumstance which allows by means of the sensor 31 to generate an analog signal function of the height thereat the level L of coffee is and therefore of the quantity really present in the container 13.
- a circuit 3 ID is mounted upon the strip 3 IA, electrically connected to the conductive strips 3 IB and 31C.
- the circuit 3 ID is of the kind known on itself and it constitutes, together with the strips 3 IB and 31C (forming the sensible elements) the real capacitive sensor.
- the circuit 3 ID is connected to the control unit 27 which, based upon the differential signal obtained by the circuit 3 ID, properly digitalized, supplies the user an indication about the real level of coffee in the reservoir 13 and in case an alarm when this level goes below a threshold, for example the one represented with a dash-dot line S in f ⁇ gure3.
- Figure 5 shows schematically a sensor analog to that of figure 4, wherein however two pairs of strips equal therebetween are provided, only two thereof are visible in figure.
- Each pair of strips designated with 3 IX and 3 IY, is connected to the detection circuit 3 ID and it has an elongated triangular shape.
- the two triangles are arranged in inverted positions to cover a substantially rectangular surface. In this way the effect of the coffee level upon the capacity of the two pairs of strips varies in different way for one pair and for the other one, so that the sensor can supply a stronger signal.
- FIG 5 an additional embodiment is shown, wherein instead of a single sensor 31 N sensors designated with 31(1), 31(2), 31(3), ... 31(n) are used.
- Each one of the sensors comprises a pair of strips 31B/31C and a circuit 3 ID electrically connected to the two strips. These can have, as shown in figure 6, a much smaller development than that of the strips 3 IB and 31C of figure 2.
- These sensors are arranged in sequence along the direction F of lowering of the level of coffee in the container 13, so that each one can supply a signal of presence/absence of coffee and the combination of these signals supplies an indication of the real level of coffee in the container.
- it is a digital solution to obtain information similar to the one obtained in analog way with the arrangement of figure 5, that is of figures 2, 3 and 4.
- the sensors of figure 6 and the sensors of figure 5 can be applied on the container 13 in a configuration analogous to the one represented in figure 3.
