  However, since the conventional beverage extractor does not have a backup power source, there is a problem that extraction cannot be performed in a place where there is no commercial power source even if it is attempted to extract a beverage by moving to a table or the like after boiling.

  The present invention solves the above-described conventional problems, and an object of the present invention is to provide a beverage extractor that can extract a beverage such as coffee or tea even in a place without a commercial power source.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiment.

(Embodiment 1)
FIG. 1 is a diagram showing a schematic configuration of a beverage extractor according to the first embodiment of the present invention, and FIG. 2 is a configuration diagram of a control circuit unit of the beverage extractor. In addition, about the same part as the said conventional drink extractor (FIG. 3), the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  In FIG. 1, a container 1 contains a liquid such as water, and a heating means 2 boils the liquid in the container 1 and then keeps the temperature. The temperature detection means 3 includes a temperature detection element such as a thermistor and detects the temperature of the liquid in the container 1. The water discharge path 4 is a path for discharging the liquid in the container 1 to the outside, and the electric pump 5 is installed in the middle of the water discharge path 4 and discharges the liquid in the container 1.

  The beverage fixing part 6 is a place where the beverage pack 12 or the beverage powder is installed. A backup power source 7 supplies power to the electric pump 5 and each electric component described later when commercial power is not supplied through the power cord 16.

  The pump drive unit 9 drives the electric pump 5 by a signal input from the control unit 11. The power supply detection means 10 detects the voltage of the backup power supply 7. The notification unit 13 is configured by an LED, an LCD, a buzzer, or the like, and performs notification using a signal from the control unit 11. The extraction switch 14 is operated to send a signal to the control means 11.

  About the drink extractor in this Embodiment comprised as mentioned above, operation | movement and an effect | action are demonstrated below.

  First, when commercial power is input through the power cord 16, the controller 11 determines that the temperature of the liquid in the container 1 is lower than the second predetermined temperature by the temperature detector 3. A signal is sent to 2 to start heating. Thereafter, the control means 11 performs control so that the hot water heating operation is terminated and the heating means 2 performs the heat retaining operation when a detection of a temperature equal to or higher than the third predetermined temperature or a predetermined temperature gradient is detected.

  Next, when the extraction switch 14 is operated when there is no outlet or the like and no commercial power is input, the signal is input to the control means 11. The control means 11 supplies the voltage of the backup power supply 7 to the electric pump 5 and outputs an operation signal to the pump drive means 9. When the electric pump 5 is driven, a predetermined amount of liquid in the container 1 is discharged and supplied to the beverage pack 12 or beverage powder in the beverage fixing unit 6 for extraction.

  The voltage detection means 10 detects the voltage of the backup power source 7 as needed, and when it becomes equal to or lower than the first predetermined voltage, the control means 11 stops driving the electric pump.

  In FIG. 2, reference numeral 23 denotes a commercial power supply that is supplied to the control circuit through the power cord 16, and is input to the microcomputer 11 a in the control means 11 through the rectifier circuit 17, the transformer circuit 18, the backflow prevention diode 19, and the regulator 21. The output of the diode 19 (hereinafter referred to as Vu power supply) is also connected to the extraction switch 14 and the electric pump 5. Reference numeral 8 denotes a backup power supply switching unit, which includes a transistor 8a, a resistor 8b, and a diode 8c.

  The control means 11 includes a microcomputer 11a, a central control room 11b, an AD converter 11c, and a power supply recognition device 11d. The current limiting resistor 22 is that the commercial power supply 23 is supplied through the power cord 16. The central control chamber 11b is heated based on the divided voltage signals of the thermistor 3a and the resistor 3b which are components of the temperature detecting means 3 when the power is recognized by the power source recognition device 11d configured in the microcomputer 11a. (The control circuit configuration of the heating means 2 is not shown in FIG. 2). Upon receiving a signal input from the extraction switch 14, the central control chamber 11b drives the electric pump driving transistor 9a through the resistor 9b, operates the electric pump 5, and discharges the liquid in the container 1.

  Next, when the power recognizing device 11d recognizes that the commercial power source 23 is not supplied, the microcomputer 11a enters a signal input waiting state (hereinafter referred to as a backup mode) from the extraction switch 14. At this time, the central control room 11b outputs a signal to the backup power source switching unit 8, turns on the transistor 8a, and supplies power from the backup power source 7.

  When a signal is input from the extraction switch 14 when the main body is in the backup mode, the central control chamber 11b drives the electric pump driving transistor 9a via the resistor 9b, and a predetermined amount of liquid in the container 1 is obtained. Is discharged.

  The voltage level of the backup power supply 7 (remaining energy of the backup power supply) detected by the resistors 10a and 10b of the voltage detection means 10 is recognized by the AD converter 11c in the microcomputer 11a, and is determined in advance. The central control chamber 11b stops driving the transistor 9a via the resistor 9b, and stops the operation of the electric pump 5.

  As described above, the beverage extractor according to the present embodiment includes the backup power source 7 that supplies power to the main body, and supplies the voltage of the backup power source 7 to the electric pump 5 when the commercial power source 23 is not input. By providing the control means 11 that drives and discharges a predetermined amount of liquid and performs an extraction operation, it becomes possible to extract a beverage even when there is no commercial power supply 23, and the user's range of use is widened and user-friendly.

  Further, the control means 11 does not stop the electric pump 5 during the extraction, but postpones until the predetermined amount of drainage is completed and the extraction operation is completed, so that the user dissatisfaction due to the sudden stop during the extraction. Can be prevented.

  Further, when a voltage higher than the first predetermined voltage is set in advance as the second predetermined voltage, and the second predetermined voltage is detected by the AD converter 11c, the central control room 11b causes the resistor 24 to be connected. Through the flashing of the notification means 13 (here, the LED), the user can be notified that the remaining energy of the backup power supply 7 is low, and the user can be backed up before the extraction operation becomes impossible. Since the power supply 7 can be urged to be charged or the backup power supply 7 replaced, the chance that the backup power supply 7 cannot be suddenly extracted when the power cord 16 is not connected to the commercial power supply 23 is reduced. be able to.

  The backup power source 7 in this embodiment can obtain the same effect as this embodiment regardless of whether it is a primary battery such as a manganese dry battery or an alkaline dry battery, or a secondary battery such as a nickel cadmium storage battery.

  When the electric pump 5 is stopped in the central control chamber 11b when the AD converter 11c detects a temperature lower than a predetermined temperature through the temperature detection means 3, the user is out of the proper temperature. The provision of a beverage can be prevented, and the dissatisfaction of the user due to the extraction of the beverage deviating from the appropriate temperature can be eliminated.

  As described above, the beverage extractor according to the present invention can extract a beverage even in a place where there is no commercial power source, and can provide a user-friendly beverage extractor with a wide range of use by the user.
