Milk and milk foam switching system for coffee maker

Abstract

The invention discloses a milk and milk foam switching system for a coffee maker, and the system provided by the invention comprises a control unit, a milk foam generator, a steam delivering pipeline for providing steam for the milk foam generator, a milk delivering pipeline for providing milk for the milk foam generator, and an air delivering pipeline for providing air for the milk foam generator, wherein a switching device for controlling the switching on and off of the pipelines is arranged on the air delivering pipeline and is electrically connected with the control unit, the switching device is controlled by the control unit to be switched on and off, when milk foams are made, the switching device is controlled by the control unit to be switched on and deliver air to the milk foam generator; and when hot milk is made, the switching device is controlled by the control unit to be switched off so as not to deliver air to the milk foam generator. In the invention, the control system is adopted to synchronously control the switching on and off of the pipelines so as to eliminate the original situation that the chosen making procedure and the finally finished product are inconsistent as a manual mechanical valve is not in correct position.

Description

technical field [0001] The invention discloses a control system, in particular to an automatic switching system between milk and milk foam for a coffee machine. Background technique [0002] Now the development of coffee machines is developing in the direction of multi-functional and fully automatic. In addition to brewing coffee, it is also connected with a milk frother, which has the function of making fresh milk foam. The production of milk foam must have enough air to be successful. By controlling the input of air, the milk frother can be switched between making milk foam and heating milk. In the prior art, the input of control air is mainly controlled by manual machinery. The opening and closing of the valve is controlled by the rotation of the knob. When the knob is rotated to the hot milk position, the air input pipe is closed, and only milk and steam are input into the milk frother. The two are mixed together to make hot milk; when the knob is rotated to the milk fo...

AI Technical Summary

Problems solved by technology

Due to the asynchrony of the mechanical control and the entire circuit control system, if you forget to turn the knob to the correct position, the correct production process cannot be performed

For example, if you turn the knob to the hot milk position, even if the system selects the milk frothing program, because the air input pipe is closed at this time, there is no air input in the milk frother, so the produced is hot milk and cannot be produced. milk foam
