6 is a cross-sectional view showing a state of use of the coffee production apparatus according to an embodiment of the present invention.

As shown in FIG. 6, the process of cooling the lead wire 16 around the socket housing 18 of the heating device 12 while the heating device 12 is operated for coffee extraction is shown.

To this end, when the water in the lower flask 11 of the extraction mechanism 24 is boiled using heat of light irradiated from the general lighting halogen lamp 15 of the heating device 12, the halogen lamp for general lighting A large amount of heat is generated around the lamp housing 22 in which the lamp socket 17 belongs to the feed back row of 15, and the lead wire 16 receives the influence of the heat generated.

At this time, when the blower fan 19 installed inside the heating table assembly 13 is operated, external air is introduced into the cooling induction pipe 20, and the air thus introduced is guided upward while the socket housing is operated. Since the bottom part of 18 and the lead wire 16 hanging underneath can be cooled, the lead wire 16 can be protected from heat.

In addition, the air that cools the lamp socket 17 and becomes hot is a lamp housing cover 27 mounted to the vent 21b of the cooling induction pipe 20, the inside of the lamp housing 22, and the lamp housing 22. It can be discharged to the outside while passing through the vent (21a) of the, and the hot air is discharged from the lower flask 11 because it forms an air curtain around the lower flask 11 while proceeding upwards The heat can be trapped and eventually increase the thermal efficiency.

For example, the lower flask 11 as well as the upper flask 10 are not influenced by the outside temperature, i.e., the outside temperature in summer or winter, the temperature by other heat sources in the surroundings, etc. by the air curtain. ) Can be accurately controlled without deviation.

On the other hand, the present invention by providing a time to stir coffee, waiting time, coffee down time, and the like, it provides an operating method that anyone can drop delicious coffee regularly even if you are not skilled.

To this end, a control unit 14 is provided which compares the temperature value of the water input from the water temperature sensor 26 with a predetermined temperature value, and informs a predetermined working time point and method.

At this time, the control unit 14 is fixed at a time when the temperature of the water, which is the time when the upper flask is erected, reaches a predetermined temperature, when the water starts to boil and the water rises to a certain level by the upper flask, when the water is all raised to the upper flask. By calculating the time of staying, etc., the control is performed to inform the operator of the exact time and method of operation by text, alarm, and voice.

This will be described in more detail with reference to FIG. 7 as follows.

7 is a flow chart according to the control method for producing coffee in the coffee production apparatus using the siphon principle of the present invention.

As shown in FIG. 7, the present invention may be controlled in the following order as a control method for coffee production performed by the control unit.

First, when the main switch of the input unit is turned on (on), the operation for overall control of the device is started after the power is increased (S100).

 Next, when the temperature of the water in the lower flask reaches a constant temperature, for example, about 97 ~ 98 ℃ about to erect the upper flask is erected and guided to cover the lid.

Second, when the water in the upper flask rises to a certain level, for example 1/2 or 1/3, the lid is opened and guided to stir the coffee powder to mix well.

Third, guide the time to stay for a certain time from the time when all the water rises to the upper flask.

That is, when the temperature (T1) of the water in the lower flask is measured by the water temperature sensor (S110), and the temperature button of the control unit on the front of the lower case is pressed (S120), the water temperature measured by the water temperature sensor ( T1) is automatically input to the control unit, and at the same time, the halogen lamp is turned on and heating starts (S130).

Here, in order to boil the water in a short time, it is preferable to preheat the vessel (bottom flask) and then add the hot water as possible to the flask first, since the temperature of the original water determines the boiling point arrival time.

In other words, the heating time of the halogen lamp starts to boil, and the upper flask will calculate the scheduled time for the water to rise in the main chip of the control unit, and the text message or "beep" will be notified before the scheduled time is reached. .

Next, after the text guide, about half of the water in the upper flask to stir the coffee powder to the water well mixed with the bar, so at this point, stir the text message or "beep", or voice " Stir well. " (S160-S170)

Then, after all of the water in the lower flask has risen to the upper flask, if the lower flask continues to be heated, the coffee will remain in the upper flask without falling down and can remain on the top for only a few seconds after the coffee is completely diluted with water. Since it is an important point to change the taste of coffee, it is entered into the program of the control unit, and when this time is reached, the halogen lamp is automatically turned off and the extracted coffee is lowered back into the lower flask (S180 ~ S190).

Subsequently, after the coffee comes down, it can be switched to the warming mode, and this point also informs that the coffee is completed by a "beep" sound or a text message. (S210 ~ S220)

After removing the lower flask from the upper flask, the lower flask is removed from the heating apparatus and the power of the warming mode is cut off, thereby completing the coffee extraction process.

On the other hand, in order to operate the control unit as described above, the control unit includes a main computer CPU, a graphic LCD window for text or picture messages, and a means for adjusting the heat amount by controlling current or voltage.

8. Automatic heating can be started after the heating is complete and the coffee is lowered into the lower flask (current control).

9. All power can be switched off by removing the lower flask from the heater.

10. The water boiled by the water temperature sensor before the start of operation measures the temperature of the bottom flask containing it, inputs it to the selected heater, and when it is placed in the heater, assumes that the current water temperature reaches the boiling point. Set it.

In this case, the home time may calculate the compensation time by measuring the ambient temperature.

11. When the flask is to be preheated, it can be preheated to the preheat temperature and time set on the indicator by placing the flask in the correct position and turning on the main switch.

12. Temperature and time can be set during operation as well as the setting can be saved with the main switch ON.
