Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a siphon-type beverage maker.

[Technical Background of the Invention] Conventionally, a coffee making machine is well known as a siphon type beverage making machine of this type. FIG. 6 shows the conventional siphon type coffee making machine. In the figure, reference numeral 1 is a base having a handle portion 2, and a holder 3 is provided on the base 1. Further, 4 is a lower container, 5 is an upper container having a water pipe 6 and a filter 7. Coffee powder is put in this upper container 5, while an appropriate amount of water matching the amount of coffee powder is put in the lower container 4. The lower container 4 is held by the holder 3, and then the upper container 5 is joined to the lower container 4 and held in the same manner, and the upper container 5 is connected to the lower container 4 through the water pipe 6 and the filter 7. To communicate with. Then, in this state, the heater 8 is placed below the lower container 4 to generate heat to heat the water in the lower container 4.
Then, the water in the lower container 4 eventually boils and generates steam to gradually increase the steam pressure, so that when the water pressure in the lower container 4 reaches a certain pressure or higher, the hot water in the lower container 4 is caused by the steam pressure. It is fried in the upper container 5 through the filter 7 and mixed with coffee powder to form a coffee liquid. Then, after that, when the heater 8 is de-energized to stop its heat generation, the lower container 4 is cooled and the vapor pressure in the inside is lowered to cause a vacuum action. The coffee liquid in the above is introduced into the lower container 4 through the filter 7 and the water pipe 6. Then, after that, the upper container 5 may be removed from the lower container 4, the handle portion 2 of the base 1 may be held, and the lower container 4 may be tilted together with the base 1 to transfer the coffee liquid to the coffee cup.

[Problems of the Background Art] In the case of the above-mentioned conventional technique, after the hot water is fried, that is, transferred from the inside of the lower container 4 to the inside of the upper container 5, the power to the heater 8 is cut off to stop the heat generation. But I had to do it one by one, which was troublesome. Further, for this reason, the user has to stay close to the coffee making machine after the heating of the lower container 4 by the heater 8 is started, which is inconvenient. Further, the heater 8 described above
The power disconnection operation must be performed at a predetermined timing after the hot water is transferred from the lower container 4 to the upper container 5, but the problem is that the taste of the coffee liquid is not constant because it is left to human hands. There were also points.

[Object of the Invention] The present invention has been made in view of the above circumstances, and therefore an object of the present invention is to manually transfer hot water from the inside of the lower container to the inside of the upper container to stop the heat generation of the rear heater. Therefore, it can be done without leaving the user busy, and the timing can be constant, and in particular, the transferred beverage does not stay in the upper container for an unnecessarily long time. It is an object of the present invention to provide an excellent beverage manufacturing machine capable of further improving the taste of beverage.

Further, as shown in FIG. 4, reference numeral 49 denotes a cylindrical portion projecting at a position corresponding to the upper container 44 in the motor case 23, in which a detection element such as a thermostat 50 is housed and fixed, and a cover 51. Are wearing. In addition, in FIG. 5, reference numeral 52 is a plug which is inserted and connected to a power outlet (not shown). Further, as shown in FIG. 5, the timer 37 has a first time switch 53 and a second time switch 54, and these both time switches 53, 54 are connected via a cam or the like not shown. It has a drive source for opening and closing as will be described later, such as a mainspring (also not shown). Thus, the motor 22 is connected to the plug 52 through the first time switch 53 in series, and the heater wire 14 of the heater 12 is connected in parallel with the series connection circuit to the thermostat 50 and the second. The time switches 54 are connected in pure series. A relay 55 has a coil 56 connected in parallel with the thermostat 50. Reference numeral 57 is an alarm, for example, a buzzer, which is connected in parallel with the motor 16 of the fan 17, and the parallel connection circuit is connected in series with the heater wire 14 via a switch 58 opened and closed by the coil 56 of the relay 55. The thermostat 50 and the second time switch 54 are connected in parallel with the series connection circuit.

Now, in the case of the one configured as described above, in using it, first, the plug 52 is inserted and connected to a power outlet (not shown), then the lid 32 is taken from the crushing case 26 and the coffee beans as the raw material are put therein, and then the Reattach the lid 32. On the other hand, the lower container 43 is pulled out from the holder 40, so that the container 44 is also removed at the same time.
Then, the upper container 44 is removed from the lower container 43, and a necessary amount of water is put into the removed lower container 43. Then, the upper container 44 is attached to the lower container 43 again, the lower container 43 with the upper container 44 attached is attached to the holder 40, and the grip 39 is further held to hold the lower container 43 and the upper container 44. The container support 38 and the container support 38 are moved toward the motor case 23 so that the upper opening of the upper container 44 covers the lid 3.
1, the side surface of the upper container 44 contacts the thermostat 50 via the cover 51, and the lower container 43 is set above the heater 12 and also above the fan 17. Then, the knob 36 is rotated to set the timer 37. Then, the first time switch 53 is first closed, which causes the motor 22 to be energized and activated, so that the cutter 27 in the crushing case 26 is rotated via the coupling 28. By the rotation of the cutter 27, the coffee beans contained therein are crushed into coffee powder in the crushing case 26, and the coffee powder is successively guided through the filter 29 to the coffee powder guide 30 and the upper container. It is put in 44. And after a certain time, the first time switch 5
When 3 is opened, the motor 22 is cut off and stopped, and the cutter 27 also stops its rotation. Further, here, the second time switch 54 is closed instead of the above-mentioned first time switch 53, so that the heater wire 14 is energized through it and the thermostat 50 which is closed at this time. The energized heater wire 14 generates heat. Therefore, the water in the lower container 43 is heated and eventually boils, generating steam and increasing the steam pressure. And when it reaches a certain pressure or more, the lower container 43
The hot water in the hot water flows through the water pipe 46 and the filter 45 due to its vapor pressure
Is fried or transferred into the upper container 44 through the inside of the upper container 44 and mixed with the coffee powder to form a coffee liquid.

On the other hand, when the hot water is transferred from the lower container 43 into the upper container 44 as described above, the temperature of the upper container 44 immediately rises, and the thermostat 50 causes the thermostat 50 to rise with the temperature of the suddenly rising upper container 44. Operate. Thus, the operation of the thermostat 50 refers to opening, so that the heater wire 14 is de-energized and the heat generation is stopped. At this time, the relay 5 is opened by opening the thermostat 50 described above.
The coil 56 of 5 is released from the short circuit so far and is energized,
The switch 58 is closed based on this energization, so that the motor 16 of the fan 17 is energized and activated, thereby rotating the impeller 15. Therefore, the lower container 43 is blown with the wind by the flow of the air blown from the suction port 19 through the suction outlet 18 by the rotation of the impeller 15 and thereby the lower container 43 is quickly cooled and the steam inside the lower container 43 is cooled. Since the pressure is lowered to cause a vacuum action, the coffee liquid in the upper container 44 falls into the lower container 43 through the filter 45 and the water pipe 46 and is stored in the lower container 43. Therefore, after this, holding the handle 39, the lower container 43 is separated from the position above the heater 12, and the upper container 44 is separated from the position in contact with the thermostat 50. Then, the upper container 44 is separated from the position above the lower container 43. It is sufficient to remove it, and hold the handle 39 again to tilt the lower container 43 to transfer the coffee liquid to a coffee cup (not shown).

As described above, according to the present embodiment, the thermostat 50 can automatically stop the heat generation of the heater 12 after the hot water is transferred from the lower container 43 to the upper container 44. Thus, it is possible to save the user from the trouble of its operation, and at the same time, from the troublesomeness of the coffee making machine, which is convenient. Further, in this case, the operation of the thermostat 50 is performed by the lower container 43.
It is performed in response to the fact that hot water is actually transferred from the inside into the upper container 44 and the temperature of the upper container 43 rises.
That is, it is carried out in accordance with the reality, and therefore, the timing of stopping the heat generation of the heater 12 can be made constant, so that the taste of the coffee liquid can be made constant. Further, when the thermostat 50 operates as described above, the fan 17 is simultaneously driven to cool the lower container 43,
This promotes a drop in the vapor pressure in the lower container 43 and thus also prevents the coffee liquid from staying in the upper container 44 for an unnecessarily long period of time, thus making the concentration of the coffee liquid excessive. It can be moderately cooked without rising, and can always be drunk deliciously.

In particular, in the case of the above embodiment, the buzzer 57 sounds at the same time as the fan 17 is driven based on the operation of the thermostat 50, whereby the completion of the coffee liquid is predicted. If it's more convenient, it can be done.

The present invention is not limited to the embodiments described above and shown in the drawings. For example, the present invention is not limited to a coffee making machine as a whole, and may be similarly applied to those making tea, for example. . Further, any of the beverage manufacturing machines does not necessarily have to have a mechanism for crushing the raw material such as coffee beans, and further, the thermostat 50
The detection element illustrated in 1 may be other than the thermostat. In addition, the alarm device exemplified by the buzzer 57 may be a lamp or the like other than the buzzer.

[Effects of the Invention] As is clear from the above description, according to the present invention, in the siphon type beverage manufacturing machine, the heat generation of the heater is stopped after the hot water is transferred from the lower container to the upper container. It can be done by the detection element, so it does not require human labor and therefore does not leave the user alone, it can be greatly convenient and the timing can be made constant and the beverage It has an excellent effect that the taste can be made constant and that the transferred beverage does not remain in the upper container for an unnecessarily long period of time, so that the taste of the beverage is not spoiled and the beverage can be always tasted deliciously.
