[0178] Under the light of the structural details given above, the
usage of the Turkish coffee cooking and serving machine is as
follows. First of all, when desired, cleaning process is realized
by means of the cleaning button (725) in the cooking compartment
(42) prior to the Turkish coffee making process. Water is sent from
the water depot (31) to the cooking compartment (42) and the walls
of the cooking compartment (42) and the cooking compartment (42)
are cleaned as a result of the vertical movement of the pushing
head (43). As a result of the vertical movement of the piston level
arm (448) and as the piston level arm (448) presses on the top
level sensor (449), the cooking compartment (42) arrives at the top
position and can be cleaned manually when desired. The desired
sugar proportion is selected by utilizing the sugar adjustment
button (722). In order to determine the number of cups of Turkish
coffee desired to be prepared, single cup button (723) or double
cup button (724) is utilized. By means of the LCD screen (721)
provided on key pad (72), the number of cups of Turkish coffee to
be made and the amount of sugar in the coffee mixture can be
monitored.
[0179] With reference to FIGS. 4 and 8, the sugar dosing system
(10) is functioning for transferring sugar to the cooking
compartment (42). The drive motor (142) begins functioning for
dosing the amount of sugar determined and selected beforehand
according to the information received from the control unit (71).
The drive motor (142) provides circular movement to the screwed
shaft (143) positioned thereon and the screwed shaft (143) rotates
in a circular manner. Circular movement is transformed into linear
movement by the nut (144). The nut (144) and the movement transfer
piece (145) connected to the nut (144) are moving upwardly. By
means of this, the sugar pushing head (13) is also pushed upwardly
and the upward movement of the sugar pushing head (13) moves the
sugar inside the sugar dosing compartment (12) upwardly and stores
the sugar in the sugar division (262). The piston level arm (149)
is moving in a one piece manner together with the movement transfer
piece (145). When the sugar is stored in the sugar division (262),
the drive motor (142) is stopped by the control unit (71). After
the sugar is stored in the sugar division (262), the drive motor
(142) begins functioning in the opposite direction according to the
movement providing upward movement of the pushing head (13). Thus,
the pushing head (13) returns to the prior position thereof and the
power of the drive motor (142) is interrupted by the control unit
(71). When the piston level arm (149) presses to the top level
sensor (150), this shows that sugar in the sugar dosing compartment
(12) is finished. As the piston level arm (149) presses the bottom
level sensor (151), this shows that the sugar dosing compartment
(12) is ready for putting sugar therein.
[0180] After the sugar is stored in the sugar division (262) at the
desired amount, the transfer drive motor (264) of the transfer
system (26) is moving and the transfer drive shaft (265) begins
rotating in a circular manner. As a result of the circular movement
of the transfer drive shaft (265), the dosing piece (261) begins
rotating in direction A around the assembly axis (a) and when the
sugar division (262) corresponds to the top of the cooking
compartment (42), it stops. In said position, the sugar inside the
sugar division (262) is falling into the cooking compartment (42)
by means of the gravitational force. After the transfer of the
sugar to the cooking compartment (42) is completed, the transfer
drive motor (264) is operated in the opposite direction and the
dosing piece (261) is rotating in direction B which is opposite to
direction A around the assembly axis (a) and it returns to the
previous position thereof and the control unit (71) stops the
transfer drive motor (264) by interrupting the power thereof.
[0181] With reference to FIGS. 5 and 8, after sugar is transferred
to the cooking compartment (42), Turkish coffee is transferred. The
coffee dosing system (20) is functioning for the Turkish coffee to
be transferred to the cooking compartment (42). The drive motor
(242) begins functioning according to the information obtained from
the control unit (71), in order to dose the amount of Turkish
coffee determined and selected beforehand. The drive motor (242)
provides a circular movement to the screwed shaft (243) positioned
thereon and the screwed shaft (243) is rotating in a circular
manner. The circular movement is transformed into linear movement
by the nut (244). The nut (244) and the movement transfer piece
(245) connected to the nut (244) are moving upwardly. By means of
this, the coffee pushing head (23) is also pushed upwardly, and the
upward movement of the coffee pushing head (23) is moving the
Turkish coffee in the coffee dosing compartment (22) upwardly in
order to store the Turkish coffee in the coffee division (263).
Together with the movement transfer piece (245), the piston level
arm (249) is beginning movement in a one-piece form. When the
Turkish coffee is stored in the coffee division (263), the drive
motor (242) is stopped by the control unit (71). After the Turkish
coffee is stored in the coffee division (263), the drive motor
(242) begins functioning in a direction opposite to the movement
providing upward movement of the coffee pushing head (23). Thus,
the coffee pushing head (23) returns to the prior position thereof
again and the power of the drive motor (242) is interrupted by the
control unit (71). When the piston level arm (249) presses on the
upper level sensor (250), this shows that the Turkish coffee in the
coffee dosing compartment (22) is finished. As the piston level arm
(249) presses on the bottom level sensor (251), this shows that the
coffee dosing compartment (22) has become ready for placing Turkish
coffee.
[0182] After the Turkish coffee is stored in the coffee division
(263) at the desired proportion, the transfer drive motor (264) is
moving and the transfer drive shaft (265) begins rotating in a
circular manner. As a result of the circular movement of the
transfer drive shaft (265), the dosing piece (261) is beginning
rotating in direction B around the assembly axis (a) and the coffee
division (263) is stopping when it arrives just above the cooking
compartment (42). In said position, the Turkish coffee in the
coffee division (263) falls into the cooking compartment (42) by
means of the gravitational force. After the Turkish coffee is
transferred to the cooking compartment (42), the transfer drive
motor (264) is operated in the opposite direction, and the dosing
piece (263) returns to the prior position by rotating in direction
A which is opposite to the direction B around the assembly axis (a)
and the control unit (71) stops the transfer drive motor (264) by
interrupting the power thereof.
[0183] With reference to FIG. 6a, after the transfer of the Turkish
coffee to the cooking compartment (42) is completed, water is
transferred into the cooking compartment (42) depending on the
predetermined cup number. The water pump (32) begins functioning as
a result of the information received by the control unit (71). The
water, existing inside the water depot (31), is pumped to the water
pipe (33) by means of the water pump (32) and it is transferred to
the cooking compartment (42) through the water outlet (34) by means
of water pipe (33).
[0184] With reference to FIGS. 6a and 6b, the cooking process is
beginning after the Turkish coffee, sugar and water are transferred
to the cooking compartment (42). For the cooking process, the
control unit (71) gives command to the heater (421) and provides
functioning thereof. The temperature of the coffee mixture started
to be cooked by the heater (421) is measured by the temperature
detector (423). The measured temperature information is sent to the
control unit (71) and the control unit (71) interrupts the power of
the heater (421) when the temperature, required for cooking the
coffee mixture, is reached. The bi-metal thermic unit (422)
provides the heater (421) to be protected against overheating. The
power control is decreasing in the heating step in the cooking
process. Power control is firstly controlled by the relay and
afterwards by the thyristor and finally by the final switching. The
coffee mixture subject to the cooking process is mixed within
predetermined intervals after a certain temperature. The mixing
motor (428) transfers the movement to the motor shaft (4281) in
order to provide movement to the mixing arm (425) positioned on the
pushing head (43) and in order to provide movement to the annular
piece (427) connected to the mixing arm (425) from one end. The
annular piece (427) and the mixing arm (425), connected to the
motor shaft (4281) from one end are beginning rotation. The spring
(426), disposed onto the annular piece (427), increase the
efficiency of the mixing process. Thus, the coffee mixture,
comprising Turkish coffee, sugar and water, become homogeneous
inside the cooking compartment (42). Moreover, the temperature of
the coffee mixture inside the cooking compartment (42) becomes
homogeneous. Said mixing and cooking process is realized in the
cooking position (i). When the cleaning button (725) provided on
the key pad (72) is pressed for certain time duration, the
temperatures adjusted according to predetermined parameters are
displayed on the LCD screen (721). The temperature adjustment is
realized by utilizing single cup button (723) and the double cup
button (724). Resistance is utilized as the heater (421); however,
in the alternative embodiments of the present invention, heater
(421) types like induction heater, gas heater can be used instead
of resistance.
[0185] With reference to FIGS. 6b and 6c, in order to transfer the
cooked coffee mixture into the cup, first of all, when the
temperature of the coffee mixture reaches a predetermined level,
depending on the power received from the control unit (71), the
drive motor (451) begins functioning in order to provide the
pushing head (43) to advance from the cooking position (i) to the
discharge position (ii). The drive motor (451) provides a circular
movement to the screwed shaft (442) positioned thereon and the
screwed shaft (442) is also rotating in a circular manner. As in
the sugar dosing system (10) and in the coffee dosing system (20),
the circular movement is transformed into linear movement by the
nut (443). The nut (443) and the movement transfer piece (444),
connected to the nut (443), are moving upwardly. By means of this,
the pushing head (43) is pushed upwardly and the upward movement of
the pushing head (43) is moving the coffee mixture in the cooking
compartment (42) upwardly. The coffee mixture is rising up to the
discharge spout (429) and flows into the cup positioned on the
service base (60). Since the coffee mixture subject to the cooking
process begins rising, first of all, the foam of the coffee mixture
is poured into the cup through the discharge spout (429). Thus,
foam loss is prevented. Since the pushing head is inclined as a
result of the inclined form of the base plate (80), said process is
facilitated. As the cooking compartment (42) is arriving at the
discharge position (ii), the drive motor (451) is stopped by the
control unit (71). Since the cup and the service base (61) are
positioned under the discharge spout (429) and since the coffee
mixture is arriving at the discharge spout (429) directly from the
cooking compartment (42), the coffee mixture is prevented from
pouring to the outer environment.
[0186] After the coffee mixture is completely discharged to the
cup, the drive motor (451) begins functioning in the opposite
direction with respect to the movement providing the upward
movement of the pushing head (43). Thus, the pushing head (43)
returns to the cooking position (i) back again. In this case, the
power of the drive motor (451) is interrupted by the control unit
(71). The piston level arm (448) presses the bottom level sensor
(450), and this shows that the cooking and serving system (40) is
in a ready position for cooking and serving the coffee mixture.
While the coffee mixture is being discharged to the cup, two
short-duration mixing processes are applied, thus the coffee
mixture is discharged completely from the cooking compartment (42)
and there remains no foam in the cooking compartment (42) and the
walls of the cooking compartment (42) are also cleaned. One of the
members affecting the cleaning process is the vertical movement of
the pushing head (43).
[0187] Since the service base (60) comprises holes, in case of any
overflow from the cup, the overflowing coffee mixture can be held
on the service base (60) and does not flow to the outer
environment. With reference to FIG. 7, if single cup of coffee
mixture is to be served, the cup is placed such that the two
discharge spouts (429) are existing inside the cup, and if a couple
of cups are to be utilized, the two discharge spouts (429)
discharge the coffee mixture into the two cups separately.
[0188] In an alternative embodiment of the present invention, the
Turkish coffee, the sugar and the water can be put manually into
the cooking compartment (42). With reference to FIG. 7, pluralities
of Turkish coffee cooking and serving machines can be placed side
by side, and a Turkish coffee cooking and serving system can be
formed and Turkish coffee can be served to pluralities of cups.
Moreover, instead of the drive mechanism (141) provided in the
sugar dosing system (10), instead of the drive mechanism (241) of
the coffee dosing system (20) and instead of the drive mechanism
(441) provided in the cooking and serving system (40), pneumatic,
hydraulic and electrical pistons can be utilized. The movement can
also be provided manually by man power.
[0189] 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.
