The following symbols are used so that the present invention is understood better:
L. Measured level
Llim. Limit level value predetermined by the producer
The coffee machine (1) comprises a body (2), a brewing chamber (3) disposed inside the body (2), a heater (4) providing the heating of the brewing chamber (3), a level sensor (5) providing the measurement of the water-coffee mixture in the brewing chamber (3) during brewing.
In the coffee machine (1), coffee is delivered to the brewing chamber (3) automatically or by the user filling manually. As the user gives the start brewing command, water is delivered to the brewing chamber (3) from the water tank ( not shown in the figures) by a pump (not shown in the figures) and the water conduit (not shown in the figures) and the heater (4) provides the brewing of the coffee by heating the brewing chamber (3). The level sensor (5) helps in deciding whether or not the brewing process is completed by measuring the level of the water–coffee mixture in the brewing chamber (3). The coffee that is ready in the brewing chamber (3) is poured into a glass or a pot.
The level sensor (5) is preferably an infrared sensor and measures the height of the water–coffee mixture from the base of the brewing chamber (3). When the coffee is brewed and ready, the level rises with the foam formed thereon and the level sensor (5) provides the decision of whether or not the brewing process is completed to be made.
The coffee machine (1) of the present invention comprises a control unit (6) that enables the level to be measured by means of the level sensor (5) when the brewing chamber (3) is empty at the beginning of the brewing process, in other words before transferring coffee or water into the brewing chamber (3) and that compares the measured level (L) with a predetermined limit level value (Llim) to determine the dirtiness status of the brewing chamber (3).
When coffee residues accumulate in the brewing chamber (3), accumulating residues form a layer on the base and side walls of the brewing chamber (3). In this situation, the level (L) obtained in the measurement performed by the level sensor (5) is greater than the value obtained in the measurement performed when there is no coffee residue or any other thing in the brewing chamber, in other words when the brewing chamber (3) is clean. The producer saves the value measured by the level sensor (5) when the brewing chamber (3) is clean as zero into the memory of the control unit (6). By accepting the measurement performed when the brewing chamber (3) as zero, the need for a reference value to be used during the comparison of the measurement values and thus, when a layer is formed in the brewing chamber (3) due to coffee residues, the height of the layer can be directly measured by the level sensor (5). The producer determines a limit level value (Llim) within certain tolerances as a result of conducted experiments and this limit level value (Llim) is saved in the memory of the control unit (6).
In another embodiment of the present invention, the level sensor (5) measures the distance between the same and the brewing chamber (3). In this case, the measurement values received from the level sensor (5) are calibrated so that the value measured when the brewing chamber (3) is zero and processed by the control unit (6).
The control unit (6) enables the level to be measured by the level sensor (5) at the beginning of the brewing process and compares the measured level (L) with the limit level value (Llim). If the measured level (L) is greater than the limit level value (Llim), in other words if more coffee residue than the limit amount projected by the producer accumulates in the brewing chamber (3), it is decided that the brewing chamber (3) is dirty. It is decided that the brewing chamber (3) is clean if the measured level (L) is equal to or smaller than the limit level value (Llim).
In an embodiment of the present invention, the control unit (6) enables the user to be warned if the measured level (L) is greater than a predetermined limit level value (Llim), in other words when it is decided that the brewing chamber (3) is dirty. In this embodiment, the user is warned by audio and/or visual warnings that the brewing chamber (3) is dirty. Then, by, if available, starting the automatic cleaning mechanism or by the brewing chamber (3) being manually cleaned by the user, the brewing chamber (3) can be cleaned.
In another embodiment of the present invention, the control unit (6) does not start the brewing process if the measured level (L) is greater than a predetermined limit level value (Llim), in other words when it is decided that the brewing chamber (3) is dirty. In this embodiment, the control unit (6) enables the level to be measured by the level sensor (5) at certain intervals and prevents the start of the brewing process until the measured level (L) is equal to or smaller than the limit level value (Llim).
In another embodiment of the present invention, the coffee machine (1) comprises a cover (7) that is disposed on the body (2) and that enables the user to access the brewing chamber (3) and the control unit (6) enables the cover (7) to be opened if the measured level (L) is greater than a predetermined limit level value (Llim), in other words when it is decided that the brewing chamber (3) is dirty. Thus, by enabling the cover (7) to open automatically in the coffee machines (1) wherein the brewing chamber (3) is cleaned by the user, the user can more easily access the brewing chamber (3).
In another embodiment of the present invention, the control unit (6) starts the brewing process by operating the heater (4) if the measured level (L) is equal to or smaller than a predetermined limit level value (Llim), in other words when it is decided that the brewing chamber (3) is clean.
In another embodiment of the present invention, the coffee machine (1) is suitable to prepare Turkish coffee.
The control method of the present invention used in the above-disclosed coffee machine (1) and executed by the control unit (6), comprises the following steps for determining the dirtiness status of the brewing chamber (3),
- measuring the level in the empty brewing chamber (3) by the level sensor (5) (101),
