Description

The invention relates to a device for preparing mocha coffee, with a cooking vessel, and an electric heater and a temperature sensor electrically isolated from it, but thermally connected to the vessel, i.e. such that it can be thermally connected to it.

Mocha-coffee is prepared by boiling water in a cooking vessel to which ground mocha is added. According to the Elektronik Sanayi S.A. catalog, an electric mocha coffee machine is known for preparing Turkish mocha coffee, which prepares Turkish mocha coffee from water, ground mocha and sugar. This well-known device for preparing mocha coffee has the disadvantage that the vessel for cooking Turkish mocha coffee is under electrical voltage, which is why when handling this well-known device for preparing mocha coffee, due to the possibility of electric shock, there is a significant risk to life and health .

The task of this invention is the further development of devices of the above-mentioned type, but of such a kind, that with safe use in operation and mainly automatically enables the preparation of Turkish mocha coffee.

The invention solves this task by means of the features specified in claims 1 and 10.

The invention shows advantages over known devices, because with a compact design, the device is safe to handle and prepare Turkish mocha coffee and does not require any attention until the coffee is ready, because coffee preparation is mainly automated.

Other advantages of the embodiment of the present invention will be apparent from the subclaims and description that follows.

The first example of the embodiment (Fig. 1) of the invention refers to the device 1, which actually includes a container 2 for boiling water or mocha-coffee, and with respect to the container for cooking 2, an electrically isolated, but thermally connected, electric heater 5 and in the container for cooking immersed temperature sensor 11.

Also immersed in the cooking vessel 2 is a stirring rod 3 with a stirring paddle 4, whereby, when the stirring rod is engaged, the paddle 4 rotates just above the heater 5 in the cooking vessel 2. Placing the paddle 4 very close to the heater 5 promotes is the formation of foam. The motor 17 is used to drive the mixing rod 3.

Furthermore, in the upper part of the cooking vessel 2, the pipe for filling 8 with water also ends, from which, together with the ground mocha and sugar, which are also added to the cooking vessel 2, Turkish mocha-coffee is produced by heating.

The water filling pipe 8 that ends in the cooking vessel 2 is firmly connected to the cooking vessel 2 in this embodiment of the invention.

The control unit 10, which takes electricity from the electrical network 12, supplies electricity through lines 13, 14 to the electric heater 5 until the Turkish mocha coffee is ready. The control unit 10 also turns on and off the motor 17 for the mixing rod 3, which is accomplished through electrical lines 18 and 19.

On the housing 15 of the device 1, the cooking vessel 2 with the lid 16 and the water filling pipe 8 are placed so that they can be tilted.

The tilting mechanism 9, which is controlled by the control unit 10 and is supplied with electricity via lines 20, 21, is used to tilt the brewing vessel 2 so that the finished mocha coffee can be poured through the funnel 6 of the brewing vessel 2 into another vessel, eg into a cup.

The pouring funnel 6 closes with the tilting axis 7 of the cooking vessel 2 approximately at a right angle.

In the case of another embodiment of the invention (which is not shown in the drawings), the cooking vessel 2 and the heater 5 are separate parts.

In a similar embodiment of the invention (which is not shown in the drawings), the cooking pot 2 can be removed, on the lid 16 of which the heater 5 can be inserted.

In a similar embodiment of the invention (which is not shown in the drawings), the cooking vessel 2 - after removing the heater 5 - can be moved downwards from the device 1 and placed at an angle for pouring.

In a similar embodiment of the invention (which is not shown in the drawings), the cooking vessel 2 - after removing the heater 5 - is positioned so that it can be moved downwards from the device 1 and removed. This makes it easier to clean the cooking pot 2.

In a different embodiment of the invention (Figure 2, 3, 4), in which the side and upper protective parts have been removed for the sake of clarity, the device 201 includes a frame stand consisting of a left side part 222 and a right side part 223, which pass from the bottom side respectively, in the outward-facing base parts 224, 225, and above, with the help of the lower cover sheet 226 and the upper cover sheet 227, a distance is kept between them and they are connected to each other. On the lower side, both side parts 222, 223 are connected with a gap by means of a floor plate 228.

On the lower cover sheet 226 is a drive motor 256 (Figure 5, 6, 8) for driving the mixing rod 203 with its mixing blade 204.

The electric switch 257 (figure 2, 3, 4, 5, 6) serves the device 201, especially the control unit 210, to turn it on and off.

For the sake of clarity, electrical lines and water hoses are not shown in the drawings.

Mode of operation

If you need to prepare a mocha-coffee with different components, according to the embodiment of the invention described in Figures 2 to 9, i.e. the device 201, it is necessary to turn on the power switch 257 (Figure 2, 3, 4) so that the control unit 210 (Figure 2, 3 , 6) of the electrical network (which is not drawn in the drawing) receives electricity.

The control unit 210 drives the elevator 239 so that the electric motor 250 receives electric current. This drives the gear 248 (figure 4) directly or by means of further gear transmission in the corresponding direction of rotation, whereby the gear 248 moves along the tooth rack 246 upwards. Together with the gear, the shaft 243 is driven, which is guided by the slots 244, 245. The gear 249 on the lower side of the device 201 (Fig. 3, 6), which is in engagement with the rack 247, is also used for guidance. Together with the shaft 243, it moves the base plate 240, which also raises the cooking vessel 202 upwards until the temperature sensor 211 and the stirring rod 203 with its spatula 204 are immersed deep into the cooking vessel 202.

Now water from the water tank 233 is programmed to be poured into the cooking vessel 202, and ground flour and sugar are added manually through the receiving vessels 231, 232 through the opening 238 into the cooking vessel. The control unit turns on the heater, and the mocha coffee is prepared, whereby the temperature of the mocha coffee is measured by the temperature sensor 211 and reported to the control unit 210, and the mocha coffee is mixed with the stirring rod 203.

After the prescribed time, the heater is turned off by the control unit 210 and the mixing rod 203 stops. The control unit turns on the electric motor 250 in the reverse direction, whereby the elevator 239 with the cooking vessel 202 descends. When the container is lowered, the shaft 243 abuts on the ends of the slots 244, 245, whereby the worm gear which is in engagement with the gear 248 is still driven by the electric motor 250 and climbs the gear 248. This causes the base plate 240 to tilt, in an embodiment of the invention by 95°, so that the ready-made mocha coffee can flow into the beverage container 230. After the brewing container 202 is empty, the base plate 240 is controlled by the program and returns to its initial position, so that a new working cycle of preparing mocha can begin of coffee.

According to another embodiment of the invention (which is not shown in the drawing), the cooking vessel in the device stands below the heater, while the objects placed on the elevator, namely the stirring rod with a spatula, the motor for the stirring rod and the temperature sensor for the purpose of preparing mocha- the coffees are lowered down into the cooking vessel, and when the mocha-coffee is finished, they are raised again.

The supports 251, 252 (Fig. 3, 4), which are primarily designed as U-rails, serve to hold the cup screen 258 (Fig. 10). The latter has a lower, rounded guide 259 for positioning the beverage container 230 on the perforated plate 229 (Fig. 3, 4) and above that a transparent plate 260, through which the pouring of mocha coffee into the beverage container 230 can be observed.
