    DESCRIPTION
    [0001] There are millions of machines to automatically produce espresso, displayed in homes, offices, gyms, schools and industries. The energy consumption of these machines is not optimized and the energy actually used to prepare the coffee is a very small fraction of the total absorbed power. On the one hand, we are witnessing a marked waste of energy, considering the very high number of machines existing worldwide and, on the other hand, we are unable to obtain coffee where the availability of electrical power is limited (for example, in a car or outdoors). The objective of the present invention is to make a coffee machine with high energy efficiency, capable of making coffee even in situations where the electric power supply network is not available, by connecting, alternatively, to a battery built into the utensil or available in media of transport on which it is installed (for example, the car battery). TECHNICAL STATUS
    [0002] Machines for producing espresso coffee in sizes for home or office, as shown in Figure 1, are made of at least one water reservoir (1), a pump (2) to deliver water to the heater (3) and a mixture of coffee located in the container (4), which, through the spout (11), transports the coffee to the cup (5).
    [0003] The water must be heated to approximately 90 ° C before being placed in contact with the coffee mixture, in such a way as to extract a maximum amount of aromas and essences from the mixture. The temperature sensor (12) is used in order to stabilize the heater temperature to the required temperature. The machines may additionally comprise a coffee grinder (6) connected to a coffee dispenser (13). Alternatively, grinding can take place outside the machine or even sachets or capsules, filled with a mixture of coffee and available in a variety of types on the market, can be used. A control unit (9) and a panel with keys (10) allow the administration of the operational functions of the machine, including the quantity and type of coffee to be prepared, checking the operational functions (presence of water, presence of coffee, machine ready to brew coffee, and so on). In addition, a set of auxiliary and safety devices are included, such as the water level sensor (7) and the over temperature thermostat (8).
    [0004] A crucial component in the machines currently available is the heater (3) to heat the water, because it is the component that uses the greatest amount of energy. Figure 2 is a more detailed figure of the heater in typical mode: the tube that carries the water (21) is incorporated, together with the electric heating resistor (22), in a metal block (20), normally made of aluminum . The chilled water (33) enters one end of the tube (21) and leaves heated at the opposite end (34). The current is applied to the electrical resistor (22) to heat the heater. There are two thermostats, one for regulating (12), mounted at 85-90 ° C, which keeps the water at an established temperature, periodically supplying power to the heating resistor (22) and a second safety thermostat (8), mounted at a higher temperature, capable of interfering in order to disable the heating resistor (22) if the thermostat (12) or the control system does not work.
    [0005] The operation of the heater is as follows: the resistor (22) is powered until the entire block (resistor, water pipe and thermostats) reaches a temperature of approximately 90 ° C. At this point, the resistor (22) is disconnected by the control system and is not reconnected until the temperature has dropped, for example, to 85 ° C. The heating element power varies between 1200 and 2200 Watts (1500 W being the most common value), while the supply voltage varies between 110 V and 230 V, depending on the country of operation. The thermal time constants are quite long and the heating time (with the cold machine) varies between 2 and 5 minutes, while the resistance on / off cycle (22) under operational conditions is in the order of several seconds.
    [0006] Energy used to prepare a cup of coffee:
    [0007] A cup of espresso has a typical volume of 25 CC. The water is heated from an ambient temperature of 20 ° C to approximately 90 ° C, in order to yield the coffee at approximately 85 ° C. To raise the temperature of 1cc of water by 1 ° C, 1 calorie is required, corresponding to 4.18 J. The energy used in Joules is, therefore, the product of the amount of water (25 CC) multiplied by the delta temperature (of 20 to 90 ° C), that is, 70 ° C, and multiplied by the specific heat of the water. Therefore, 25 X 70 X 4.18 = 7.315 J are needed to prepare a cup of coffee and, considering the energy also used by the auxiliary control circuits and the pump, an actual amount of approximately 8000 Joules can be calculated.
    [0008] Power absorbed by the coffee machine:
    [0009] We can identify two different operating modes of the machine. The first operating mode is for typical home use, where the machine is turned on each time a cup of coffee is brewed. The second operating mode is for use in a typical office, where the machine remains on continuously for approximately 10 hours a day and dispenses, for example, 30 cups of coffee. If we allow a heater power of 1500W, a heating time of 2 minutes and consumption of 50W with the machine on (the resistor time, when in the on mode, is 1/30 of the total), the result is that:
    [0010] In the first operating mode, the absorbed power is 1500W for 2 minutes, or in J (1 Joule = 1W x 1 second), and we have 1500 W x 120 sec. = 180,000 J. Considering the energy needed for the preparation of a cup of coffee, in relation to the total energy consumed by the machine, the result is (8000 / 180,000) x 100 = 4.44%, that is, only 4.44% of the energy used was used to prepare the coffee.
    [0011] In the second operating mode, the machine operates for 10 hours at 50 W on average, that is, 500 W, corresponding to 1,800,000 J, to which 180,000 J (previous case) for the start of operation must be added. In ten hours of operation, the machine thus consumes approximately 1,980,000 J, which, divided into 30 cups of coffee, corresponds to 66,000 J per cup. In this second operating mode, the ratio between the energy required to prepare a cup of coffee and the total energy consumed approximately by the machine for a cup of coffee proves to be 8000/66000 x 100 - 12.12%. It is therefore clear that the energy production of a coffee machine is extremely low.
    [0012] The objective of the present invention is to take the production of a coffee machine to 90% and beyond, opening the way for possibilities of modality that could not be taken into account in the past due to its high levels of consumption.
    [0013] The characteristics and advantages of the present invention will become more evident from the detailed description here below of a modality of the invention in hand, illustrated by means of a non-limiting example in the attached figures, where:
    [0014] Figure 1 is a schematic view of a coffee machine currently known and available on the market;

    [0019] Figures 5A, 5B, 5C and 5D are the complete electronic circuit diagrams of the machine appearing in Figure 4. CARRYING OUT THE INVENTION
    [0020] To achieve very high energy production, the concept of the heater to heat water needs to be completely changed. As mentioned above, a heater for a coffee machine currently consists of a metal mass ranging from 0.5 to 1 kg in weight, in which the water pipe and the resistor are embedded. This type of construction makes it simple to adjust the water temperature, in the sense that the strong thermal mass of the assembly becomes a temperature stabilizing element, which can be easily controlled by an ON / OFF thermostat operating with a cycle of several seconds. .
    [0021] In the present invention, the heater (fig. 3) is reduced to a tube (30) weighing a few grams, which has virtually no thermal inertia and must therefore be regulated at temperature by a sophisticated electronic system that regulates the temperature proportionally and extremely quickly, based on the flow of water passing through the tube.
    [0022] The advantages of the invention are immediately evident: being extremely low in mass, the heater immediately heats up, avoiding the need to maintain its temperature constantly. In this way, the heater is switched on the instant the coffee is to be prepared and is switched off at the end of the preparation. Consumption with the machine in standby mode is thus zero, while in the previous example, it is approximately 50 W. Energy consumption to heat the tube (30) is also very low, considering that the mass of the heater is only a few grams. As an example, let's consider a heater with a mass of 5 grams that needs to be taken from 20 to 90 ° C:
    [0023] 5 (heater mass in grams) x 70 (temperature range) x 0.4 (average specific heat of the metal) = 140 J. Approximately 8000 J are needed to prepare a cup of coffee and, as a result, energy used to obtain a cup of coffee thus proves to be 98.25% of the total energy used. Considering the energy also needed by the circuits and auxiliary losses, a production of the machine totaling more than 90% thus seems, in any case, to be a concrete consideration.
    [0024] The coffee machine according to the present invention thus comprises a heater (3), comprising a tube (30) predisposed to be heated in order to increase the temperature of a water flow between an inlet (33) and an outlet (34). Different types of heater (3), in several typical, but not exclusive, types of construction appear in Figures 3a, 3b, 3c and 3d. The heater (3) is indicated as rectilinear, however, it can clearly assume curvilinear, spiral, helical or other complex shapes, according to the construction requirements of the complete machine.
    [0025] The machine additionally comprises heating medium (R) which uses an electric current to produce heat and to heat the tube (30). The heating medium (R) is preferably of a resistant type, that is, it produces heat by Joule effect.
    [0026] The machine additionally comprises at least one temperature sensor (S), structured in such a way as to be substantially at the same temperature as the tube (30) and vary in resistance based on its own temperature. Given the extremely limited mass of the tube (3), the temperature sensor's response to temperature changes must be extremely fast and accurate, in order to allow efficient control of the water temperature.
    [0027] In a first mode of the machine (figure 3A), the heating medium (R) comprises the tube (30), made of conductive metal material and arranged to have an electric current passing through it between its two ends (31 ), in order to heat and heat the water flow as well. The temperature sensor (S) also comprises the metal tube (30). The water enters the tube (30) in an inlet section (33) and leaves the tube (30) in an outlet section (34), heating through a very efficient heat exchange with the tube (30), due the high relationship between the length and the diameter of the tube (30). As the variation of the electrical resistance of the tube (30) is based on temperature, by monitoring the value of the referred resistance it is possible to obtain the precise temperature of the tube and, thus, of the water. As the electrical resistance of the tube (30) is low (typically fractions of an Ohm), it is particularly suitable for battery or low voltage applications.
    [0028] In an additional modality, suitable to operate in connection with the electricity supply network, the tube (30) is arranged so as to form the secondary winding of a transformer (T) (figures 3D and 4A). The primary winding of the transformer (T) is otherwise predisposed to connect to the electricity supply network or to a high frequency generator (inverter), which is, in turn, connected to the supply network electricity. In this second case, the transformer (T) will be smaller and lighter in weight. The use of a transformer (T) makes it possible to decrease the voltage at the ends (31) of the pipe (30) to a desired value, maintaining the supply voltage available to the electricity supply network.
    [0029] Another modality suitable for operation with the main voltage is illustrated in Figure 3B. In this embodiment, the tube (30) has thin walls, is made of ceramic or similar material, which is electrically insulating, but conductive of heat or of a metal material covered with a thin layer of electrically insulating material. The heating means (R) for heating the tube (30) comprises an electrical conductor (32) wrapped around the tube or shaped by a deposition process around the tube. By passing the current between the ends (31) of the electrical conductor (32), the conductor (32) is heated and, thus, the tube (30) and the water. In this case too, the resistance of the electrical conductor (32) can vary with temperature and can therefore be used to measure the temperature of the water as in the case of the tube (30). As an alternative, to measure the water temperature, the tube (30) can be used, as in the example modality that appears in Figure 3A. The electrical conductor (32), also due to the fact that it can be rolled or molded, is provided with greater resistance and, therefore, suitable for operation with connection to the electricity supply network (110 - 230 V). The electrical conductor (32) can be deposited on the tube (30) using a silk-screen deposition method (thick film). Deposition can occur using known techniques that are equivalent in terms of operational functionality, such as spraying (sputtering), electrolysis and chemical or electrochemical deposition.
    [0030] An additional modality provides that the heating medium (R) comprises the electrical conductor (32), while the temperature sensor (S) comprises the tube (30).
    [0031] As previously mentioned, in all the modes described above, the temperature sensor (S) is really a proportional temperature measuring device. Examples of proportional temperature measuring devices consist, for example, of thermistors, integrated circuit temperature sensors, diodes, transistors, thermistors and thermocouples or other equivalent devices. The temperature sensor (S) could also take the form of a maximum temperature sensor, which is present on all machines, in order to disconnect the power supply when a maximum safety temperature is exceeded; it is connected to a circuit with two temperature settings, a lower setting for water temperature control and a higher setting for machine safety.
    [0032] In the mode illustrated in Figure 4, the machine is charged by a battery (50). The machine comprises a control or controller block (9). The controller (9) is predisposed to control a first current regulator (47). The first current regulator (47) is predisposed to transmit a precisely controlled current to the heating medium (R). A preferred example of a current regulator (47) provides the regulation of a current in a proportional manner by means of the PWM (pulse width modulation) technique. Precise control of the current transmitted to the heating medium (R) is important to maintain a constant water temperature. In the embodiment illustrated in Figure 4, the heating medium consists of the tube (30), to which the current produced by the first regulator (47) is supplied.
    [0033] The controller (9) is also predisposed to control a current generator (43). The current generator (43) is designed to transmit a measuring current to the temperature sensor (S). In the mode illustrated in Figure 4, the temperature sensor consists of the tube (30), to which the current produced by the second generator (43) is supplied. As mentioned earlier, the resistance of the tube (30) is a function of the temperature of the tube and thus of the water passing through it. The current generator (43) converts the resistance variation into a voltage proportional to the temperature.
    [0034] A processing block (40) is predisposed to measure the voltage present in the limits of the temperature sensor (S), in this case, the tube (30), when only the measurement current produced by the generator (43) is passing through him. The processing block (40) additionally provides amplification and filtration of the measured voltage, which is proportional to the temperature of the tube (30), compared to a known reference voltage (52). The processing block (40) generates an error signal (51), which is sent to the controller (9). The error signal (51) contains information on the instantaneous temperature error in the temperature sensor (S), that is, the tube (30) in Figure 4. Based on the error signal (51) received, the controller (9) controls the first current regulator (47), so that a certain current is sent to the heating medium (R), in order to bring the temperature measured by the temperature sensor (S), that is, the tube (30), to the desired value. The first current regulator (47) translates the command received by the controller (9) into an on / off ratio of a first switch (45) interposed between the battery (50) and the heating medium (R), in this case, the tube (30). The water temperature is thus proportionally regulated many times per second, as necessary in order to maintain a stable temperature under all operating conditions of the machine, from the coffee dispensing to the absence of water in the heater (3).
    [0035] A sampling block (42) is predisposed for synchronized measurement of the resistance of the temperature sensor (S), in this case, the tube (30), in the moments when only the measuring current of the generator (43) is sent to the temperature sensor (S), that is, when the first switch (45) is opened.
    [0036] A second current regulator (46) is predisposed to regulate the power applied to a water supply pump (2), in order to ensure, under all circumstances, an ideal water flow rate to prepare the coffee. The coffee mixture that has been placed in a container (4) is sprayed with water at the appropriate temperature. The coffee can be dispensed into a cup (5) via a spout (11). The use of a heater (3) of extremely small dimensions, substantially limited to the dimensions of the tube (30), allows the machine to perform water temperature control in real time. This means that the water flow does not necessarily need to remain constant as in machines of a known type, but that it can vary over time and particularly during the coffee dispensing process. It is therefore possible, for example, to send a first jet of hot water to the mixture and stop the flow for several seconds, in order to keep the mixture in an infused state. The flow then proceeds to distribute the coffee. Essentially, in the machine according to the present invention, the flow rate of the water that is heated varies over time according to a predetermined pattern as desired.
    [0037] As mentioned earlier, in the mode shown in Figure 4, the machine is charged by a battery (50). The start and end of the coffee distribution are established by the user using a push button start / stop (48). Starting from an initial stopped condition of the machine, in which all circuits are in standby mode and the current absorbed by the battery is zero, pressing the start / stop push button (48) closes the first switch (45) and determines heating the water by means of the current sent by the first regulator (47) to the tube (30). The pump (2) supplies water to the tube (30), extracting it from a reservoir (1). The operation does not change in the case where the heating means comprises the resistor (32) shown in Figure 3B.
    [0038] The current sent to the tube (30) or the resistor (32) is regulated proportionally by means of the PWM technique (pulse width modulation), by the first regulator (47), in order to maintain a water temperature constant. The current generator (43) supplies a current of a predetermined value to the tube (30), whose resistance is a function of the temperature of the tube (30) and, thus, of the water flowing through it. The processing block (40) measures the voltage supplied to the ends (31) of the tube (30) or the resistor (32), when the heating current is not passing through them (switch 45 open), but only the measuring current sent by the generator (43) is passing through them. The processing block (40) provides amplification and filtering of the signal proportional to the temperature, comparing it with a known reference voltage (52) and generating the error signal (51). The error signal (51), which contains the information on the instantaneous temperature error, is sent to the controller (9) and the first regulator (47), which transforms it into an on / off ratio of the first switch (45). The water temperature is, therefore, proportionally regulated many times per second, as necessary, in order to maintain the temperature stable under all operating conditions of the machine, from the coffee dispensing to the absence of water in the heater. The sampling block (42) synchronizes the measurement of the resistance of the tube (30) or of the resistor (32) when the first switch (45) is opened. The second current regulator (46), otherwise, regulates the power applied to the pump (2), in order to ensure, under all circumstances, an ideal flow rate of water to prepare the coffee.
    [0039] When pressing the start button (48) again, the user stops the coffee distribution at the desired level and all the machine circuits are turned off, taking the absorption back to zero again.
    [0040] An LED indicator (49) can be used to inform the user about proper coffee distribution, for example, when it remains on continuously. In the event of a malfunction (lack of water, low battery, etc.), the LED will flash, in order to signal that the coffee is not being dispensed.
    [0041] Note that, since they are known to a person skilled in the field, all auxiliary and safety circuits have been omitted for the purpose of providing a clear exposure.
    [0042] Note also that the operation of the machine is the same in all illustrated modes, that is, considering the resistor (32) in place of the tube (30) as the heating medium and the resistor (32) or other proportional temperature measuring device (8) in place of the tube (30).
    [0043] Figure 3c shows an embodiment of the invention in which the tube (30) is made of ceramic material with PTC (positive temperature coefficient). The material with PTC has a markedly non-linear resistance / temperature response: upon reaching the Curie temperature, the material increases in strength by up to 10 times in a range of 20 to 30 ° C and this makes it possible to regulate the operating temperature . Generally, the said regulation is not precise enough to maintain the water temperature at 90 ° C with a tolerance of a few degrees, but it is useful, in any case, as a measure of pre-regulation and / or safety in the event of malfunction. control circuit (9). By changing the flow rate of the pump (2) via the second regulator (46), the typical PTC temperature control can be improved, taking it within the required precision of a few degrees. The PTC resistor is thus used to regulate the flow rate of the pump (2) by means of the second regulator (46). In this case, the PWM current generator (43) is maintained at the maximum duty cycle.
    [0044] In all the modalities described and illustrated here, one or more maximum temperature sensors connected to the controller (9) are provided, which are not illustrated, since they are within the reach of a person skilled in the field. If the temperature detected by the maximum temperature sensor or sensors exceeds a predetermined threshold, the controller (9) deactivates the heating medium (R).
    [0045] In Figures 5A, 5B, 5C and 5D, the complete and functional realization of the coffee machine, which is the subject of the present invention, is indicated in the parts of electronic power and control circuits and for the realization of the heater ( 3). The construction of the water tank (1), the pump (2) and the container for the coffee mixture (4) are not described in detail, since they are standard components available on the market.
    [0046] On the contrary, the list of components used appears in Figure 6.
