In the water supply alarm device of the refrigerator beverage supply device having the configuration as described above, the operation of detecting the remaining amount of water and performing the water supply alarm will be described with reference to the accompanying drawings.

First, when the beverage container 20 is full of drinks, the level of the beverage container 20 is increased, so that the first floating member 51 and the second floating member 52 also rise along the space formed in the case 53. In this case, the first floating member 51 is raised to a height corresponding to the installation position of the first switch 61, the second floating member 52 is limited by the rising limiting projection (52a), so the lift is limited. Only the position of the projection 52a is raised. Therefore, since the first switch 61 is turned on by the magnetic force of the magnet of the first floating member 51, and the second switch 62 is turned on by the magnetic force of the magnet formed on the second floating member 52, The low signal is input to the input terminals IP1 and IP2 of the microcomputer 80. At this time, the microcomputer 80 outputs a control signal to the display means 70 and turns on all of the light emitting diodes LED1, LED2, and LED3 included in the display means 70. The amount will be displayed externally.

As the number of times of intake increases, the water level of the beverage container 20 is lowered, so that the first floating member 51 is gradually lowered according to the water level. Since it does not reach 61, the first switch 61 is turned off. However, since the position of the second floating member 52 does not change, the second switch 62 keeps on. Therefore, a high signal is input to one input terminal IP1 of the microcomputer 80 and a low signal is input to the type force terminal IP2 to determine that the water level of the beverage container 20 is in a medium state. The display unit 70 is controlled by turning off the diode LED3 and turning on the light emitting diode LED1 and the light emitting diode LED2.

In addition, when the beverage level of the beverage container 20 continues to be lowered, the position of the second floating member 52 is lowered according to the fluctuation of the water level. The second floating member 52 is located at the bottom of the beverage container 20. When positioned, the second switch 62 is turned off. Therefore, in the microcomputer 80, a high signal is input to both of the introduction force terminals IP1 and IP2, so that a small amount of beverage in the beverage container 20 remains, so that the light emitting diode LED1 of the output terminal is turned on and the other light is emitted. The diodes LED2 and LED3 are turned off.

The floating member and the reed switch of the water supply alarm device described above are not limited to the number applied to the present invention, and by using a plurality of the floating member and the reed switch to narrow the judgment range of the water level, it is possible to perform more precise residual amount detection of the beverage.
