Method and device for detecting material lack of ice cream machine

Abstract

The invention discloses a method for detecting material lack of an ice cream machine. The method comprises: firstly, detecting the rotating speed of a material cylinder of the ice cream machine through a rotating speed sensor; and then emitting a material lack alarm signal and maintaining the alarm state for a period of time when detecting that the rotating speed of the material cylinder is maintained to be less than an alarm threshold for a period of time, if the rotating speed of the material cylinder increases to exceed the alarm threshold after emitting the alarm signal, releasing the alarm state; and if the rotating speed of the material cylinder is maintained to be less than the alarm threshold for a period of time after emitting the alarm signal, forcedly shutting down and emitting the alarm signal again. The invention also discloses the ice cream machine applying the material lack detecting method. The method and the ice cream machine have the following characteristics that: 1, the control principle is simple, automatic detection and alarm functions are realized by setting procedures when the material cylinder is lack of materials, additional hardware is not added, and the cost is not increased; and 2, humanization degree is greatly improved, an alarm lamp continuously shines to remind a user when lacking materials so as to avoid the defect of frequently detecting whether enough materials are in the material cylinder, save manpower and reduce labor intensity.

Description

technical field [0001] The invention relates to a material shortage detection method for an ice cream machine, and an ice cream machine applying the method. Background technique [0002] At present, the whole industry, including the ice cream machine of imported brands, is manually adding ice cream slurry to the machine. Whether the machine is short of material, most products can only be observed by manually entering the material tank, which increases labor costs and cannot make a material shortage alarm immediately and accurately; some high-end products use liquid level sensors to sense, but this On the one hand, this method increases the production cost, and at the same time, it is difficult to guarantee the reliability when the slurry is too viscous. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a convenient and accurate method for automatically detecting the shortage of ingredients in an ice cream machine. [0004] Another objec...
