Description

SPECIFICATION

A BEVERAGE PREPARATION MACHINE TECHNICAL FIELD

The present invention relates to a cooking setting method in order to determine the temperature degree where the heat applied to the beverage mixture is interrupted, in case a beverage preparation machine is used at an altitude which is different from the sea level, where said beverage preparation machine comprises a cooking system which functions with boiling-control and wherein the beverage mixture is cooked, and a heater provided in a connected manner to the cooking chamber, and a temperature sensor positioned in a connected manner to the heater, and a control unit functioning in an integrated manner to the cooking system.

PRIOR ART

The control unit provided in beverage preparation machines which function with boiling- control detects that the beverage mixture, which includes beverage material, water and sugar when desired, has reached boiling point, and it stops heating prior to a certain temperature degree. Depending on the altitude, in case the boiling point of water is lower than the set temperature degree, the heating applied to the beverage mixture is never interrupted since water does not reach the set boiling point degree. Therefore, the beverage mixture can be deteriorated. In the models of the beverage preparation machines which interrupt heating, the beverage mixture can never be serviced. This problem particularly occurs in Turkish coffee machines which function with boiling-control and which service Turkish coffee mixture to the beverage cup.

In order to overcome said problem, setting buttons are added to beverage preparation machines. Depending on the altitude of the user, the user can use the setting buttons, and he/she can make setting by trying the setting buttons a few times in order to detect the boiling point degree in an accurate manner. This leads to difficulties for the user, and besides the user cannot use the machine until he/she makes the accurate setting. As a result, because of all of the abovementioned problems, an improvement is required in the related technical field. BRIEF DESCRIPTION OF THE INVENTION

THE DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, the subject matter beverage preparation machine is explained with references to examples without forming any restrictive effect in order to make the subject more understandable. The subject matter beverage preparation machine (1) is a device which functions with boiling-control, and comprises at least one cooking system (10) and at least one control unit (30). Inside the cooking system (10), there is at least one cooking chamber (111), a heater (1 12) providing heat to the cooking chamber (111), and a temperature sensor (113) which detects the temperature of the water or beverage mixture inside the cooking chamber (111). The control unit (30) has a processor (31) which functions in a connected manner to the cooking system (10), a memory unit (32) which functions in a correlated manner to the processor (31), and at least one circuit element (33). Moreover, there is at least one control button (34) in the control unit (30). Inside the memory unit (32), there is software which calculates the servicing degree in a correlated manner to the boiling point. The servicing degree is the power interruption degree where the energy of the heater (112) is interrupted. The beverage preparation machine (1) moreover comprises a water transfer system (20), and a drive mechanism (115) providing servicing of the beverage mixture inside the cooking system (10). The water transfer system (20) comprises a water depot (21), a water pipe (22) which transfers water to the cooking chamber (111), and water pump (23) which applies water from the water depot (21) to the water pipe (22). In alternative applications, water can be manually added to the cooking chamber (111).

The drive mechanism (115) comprises a drive motor (116) providing movement of the beverage mixture inside at least one cooking chamber (111), and at least one movement transferring element (117). In alternative applications, the drive mechanism (115) is not used, and the user pours the manually cooked beverage mixture to the beverage cup.

Before the beverage preparation machine (1) is transferred to the user, the highest temperature, reached by the water at the sea level with respect to the boiling point, is saved in the memory unit (32) by the processor (31) as the boiling degree. According to the boiling degree, the software in the memory unit (32) calculates the energy interrupting degree where the energy of the heater (112) is interrupted by means of an algorithm, and thus it calculates the servicing degree where the beverage mixture is serviced to the beverage cup, and the processor (31) saves the servicing degree in the memory unit (32). The servicing degree is calculated by subtracting a predetermined temperature degree from the maximum value measured by the temperature sensor (113).

When the beverage preparation machine (1) is to be used at an altitude which is different from the sea level, the boiling degree shall be entered to the memory unit (32) as the boiling point of the water at that altitude. For this reason, a certain amount of water is added to the water depot (21) provided in the beverage preparation machine (1), and the beverage preparation machine (1) is operated by using the control buttons (34). The processor (31) provides operation of the water pump (23), and the predetermined amount of water is transferred from the water depot (21) to the cooking chamber (11) by means of the water pipe (22). In this process, no beverage material is added to the cooking chamber (111). The processor (31) operates the heater (112) by means of the circuit element (33). Preferably triac or relay is used as the circuit element (33). The water in the cooking chamber (111) begins heating by means of the heater (112), and after the maximum temperature value, in other words, after the boiling value is reached, it is continued to be heated for certain duration, and the temperature value of the water is detected by the temperature sensor (113). After water is boiled for predetermined duration, the processor (31) reads the value sensed by the temperature sensor (113), and saves it in the memory unit (32) as the boiling degree. At the same time, the boiling degree is the highest temperature value sensed by the temperature sensor (113). Thanks to the algorithm provided therein, the software calculates the energy interruption degree where heat applied to the beverage mixture is to be interrupted and where the energy of the heater ( 12) is interrupted, and moreover it calculates the servicing degree where the beverage mixture is to be serviced into the beverage cup, and the processor (31) saves the servicing degree in the memory unit (32). The servicing degree describes how many degrees before the boiling process the beverage mixture is to be serviced.

When the beverage mixture is cooked in the altitude where boiling degree and the calculated servicing degree are recorded, the beverage mixture is serviced to the beverage cup according to the servicing degree by means of the drive mechanism (115). When the temperature sensor (113) measures the servicing degree at that altitude which is saved in the memory unit (32), the processor (31) interrupts the power of the heater (112), and according to the information received from the processor (31), the drive motor ( 16) provides the vertical movement of the movement transfer elements (117) and it provides vertical movement of the beverage mixture in the cooking chamber (111), and provides the beverage mixture to be discharged into the beverage cup. In alternative applications, when the beverage mixture reaches the servicing degree, the processor (31) interrupts the energy of the heater (112) by means of the circuit element (33), and the user manually discharges the cooked beverage mixture into the beverage cup. The beverage preparation machine (1) which functions in this manner prevents over-heating or under-heating of the beverage mixture at each altitude used inside the cooking chamber without needing any intervention. When the beverage preparation machine (1) is desired to be used in a different altitude, the same processes can be repeated. In the preferred application, the beverage preparation machine (1) is a Turkish coffee machine which functions with boiling-control.

In an exemplary application, the Turkish coffee machine comprises a sugar dosing system (40) wherein sugar is stored in order to be transferred into the cooking chamber (1 11) and where sugar is prepared for being transferred according to a predetermined amount; a coffee dosing system (50) wherein Turkish coffee is stored in order to be transferred into the cooking chamber (111) and wherein Turkish coffee is prepared for being transferred according to a predetermined amount; a transfer system (60) providing transfer of the sugar and of the Turkish coffee into the cooking chamber (111); water transfer system (20) where the water is provided to be added to the cooking chamber (111); and cooking system (10) wherein the Turkish coffee mixture is cooked and from where the Turkish coffee mixture is transferred into a beverage cup. The cooking system (10) comprises a main chamber (11) positioned at the front side of the sugar dosing system (40) and of the coffee dosing system (50). Inside the main chamber (11), there is the cooking chamber (111) at the top, a drive mechanism chamber (114) having a drive mechanism (115) providing movement of the Turkish coffee mixture provided inside the cooking chamber (1 ), and a pushing head (118) having a movement in a manner changing the volume of the cooking chamber (111) and the volume of the drive mechanism chamber (114). The pushing head (118) defines the base of the cooking chamber (111), and it is connected to the heater (112). The pushing head (118) comprises an upper cover (119) which is in a thermally conductive structure and whereon the heater (112) is positioned. The heater (112) has a temperature sensor (113) positioned in a manner extending to the cooking chamber (111) on the upper cover (119). The drive mechanism (1 15) has a drive motor (116) driving the pushing head (118). A movement transfer element (117) is provided which is in contact with the pushing head (118).

The operation of the Turkish coffee machine is as follows. After the desired amount of Turkish coffee and sugar is transferred from the sugar dosing system (40) and from the coffee dosing system (50) into the cooking chamber (111) by means of the transfer system (60), required amount of water is transferred to the cooking chamber (111) by means of the water transfer system (20). After the Turkish coffee machine is operated by means of the control buttons (34), the processor (31) gives command to the heater ( 12) for the cooking process, and it provides operation of the heater (112). The temperature of the Turkish coffee mixture which is begun to be cooked by the heater (112) is measured by the temperature sensor ( 13). The measured temperature information is sent to the processor (31), and when the predetermined temperature which is required for cooking the Turkish coffee mixture, the processor (31) interrupts the energy of the heater (112). In order to transfer the Turkish coffee mixture, which has been cooked, into the beverage cup, first of all, when the temperature of the Turkish coffee mixture reaches the predetermined level, the drive motor (116) provides the upward movement of the movement transfer element (117) and of the pushing head (118) according to the energy received from the processor (31). The upward movement of the pushing head (118) also moves the Turkish coffee mixture in the cooking chamber (111) upwardly, and the Turkish coffee mixture is discharged into the beverage cup by means of a discharge outlet (120). When the Turkish coffee machine is to be used in an altitude which is different from the sea level, a certain amount of water is added to the water depot (21) provided in the Turkish coffee machine, and the Turkish coffee machine is operated by using control buttons (34). The processor (31) provides operation of the water pump (23), and predetermined amount of water is transferred by means of the water pipe (22) from the water depot (21) to the cooking chamber (111). In this process, Turkish coffee is not added to the cooking chamber (111). The processor (31) operates the heater (112) by means of the circuit element (33). The water provided in the cooking chamber ( 1) is begun to be heated by means of the heater ( 2), and after the highest temperature value is reached, it is continued to be heated for certain duration, the temperature sensor (113) also senses the temperature value of water. After water is heated for a predetermined duration, the processor (31) reads the highest temperature value sensed by the temperature sensor (113) at the end of this duration, and it saves this value in the memory unit (32) as the boiling degree. By means of the algorithm provided therein, the software calculates the servicing degree at which the Turkish coffee mixture is serviced to the beverage cup and the processor (31) saves the servicing degree to the memory unit (32). At the altitude where the boiling degree and the calculated servicing degree are saved, when the Turkish coffee mixture is cooked; when the temperature sensor (113) measures the desired servicing degree, the processor (31) interrupts the energy of the heater ( 2) by means of the circuit element (33), and the Turkish coffee mixture is serviced to the beverage cup by means of the drive mechanism (115). The drive motor (116) provides the upward movement of the movement transfer element (117) and the pushing head (118) according to the energy received from the processor (31). The upward movement of the pushing head (118) moves the Turkish coffee mixture in the cooking chamber (11 1), and the Turkish coffee mixture is discharged to the beverage cup by means of the discharge outlet (120).

The protection scope of the present invention is set forth in the annexed Claims and cannot be restricted to the illustrative disclosures given above, under the detailed description. It is because a person skilled in the relevant art can obviously produce similar embodiments under the light of the foregoing disclosures, without departing from the main principles of the present invention.
