Abstract

An apparatus of making a soft ice-drink comprises an ice mechanism, disposed on an apparatus bed, including a shaver casing having a slit to which a shaving blade is exposed and a shaved ice discharge chute, rotatable blades, provided within the shaver casing, for cooperating with the shaving blade to shave ice blocks charged into the shaver casing, and a first drive motor for rotating the rotatable blades, a mixing mechanism, disposed on the apparatus bed and under the ice shaving mechanism, including rotary blades, rotatably supported within a container disposed beneath the shaved ice discharge chute, for mixing together a liquid material such as a syrup present within the container and shaved ice pieces discharged into the container and smashing the shaved ice pieces into granules of ice, and a second drive motor for rotating the rotary blades at high speeds, and a control circuit for controlling operations of the first and second drive motors.

Claims

1. In an apparatus of making a soft ice-drink comprising:

an ice shaving mechanism, disposed on an apparatus bed, including a shaver casing having a slit to which a shaving blade is exposed and a shaved ice discharge chute, rotatable blades, provided within said shaver casing, for cooperating with said shaving blade to shave ice blocks charged into said shaver casing, and a first drive motor for rotating said rotating blades; and

a mixing mechanism, disposed on said apparatus bed and under said ice shaving mechanism, including rotary blades, rotatably supported within a container disposed beneath said shaved ice discharge chute, for mixing together a liquid material such as syrup present within said container and shaved ice pieces discharged into said container and smashing the shaved ice pieces into granules of ice, and a second drive motor for rotating said rotary blades at high speeds;

the improvement which comprises a control circuit for controlling operations of said first and second drive motors such that after said first drive motor has been started to operate and after said first drive motor has been stopped, said second drive motor is stopped,

said control circuit comprises switch input means respectively provided corresponding to drinks for different helpings and producing signals representative of the different helpings, a counter connected to the outputs of said switch input means, a controller connected to the output of said counter, first and third timers each having one end connected in common to the output of said controller, a second timer connected to the output of said first timer and a flip-flop connected to the output of said third timer, said first and second drive motors being respectively connected to said first timer and flip-flop and driven by high level signals delivered out of said first timer and flip-flop, whereby said counter is set with "count" signals by said switch input means to deliver a high level signal to said controller, said controller receiving the high level signal delivers a high level signal to said first and third timers which in turn produce high level signals during intervals of time respectively present for said first and third timers, and said second timer produces, at the expiration of the interval of time preset for said first timer, a high level signal during an interval of time preset for said second timer and resets said counter and triggers said controller at the expiration of the interval of time preset for said second timer so that said counter produces a low level signal and said controller responds to the low level signal to deliver to said flip-flop a low level signal which resets said flip-flop and causes it to deliver a low level signal.
