Problems solved by technology
The current coffee machine has not been equipped with a device that can detect the remaining water storage in the water tank. Therefore, the control part of the coffee machine cannot adjust the amount of coffee grinding according to the remaining water storage, resulting in inaccurate grinding of coffee, which in turn leads to coffee The volume and concentration of the product are not accurate

Embodiment
[0020] Such as figure 1 As shown, the water quantity detection device includes: a column of electrodes 6 and a PCB board 8 arranged on the left side wall of the water tank part 7, the electrodes 6 are connected to the PCB board 8, and when the water level rises to touch a certain electrode 6, the PCB8 feeds back to the control device 3. The control device 3 automatically calculates the amount of water added, and then determines the working time of the bean grinding device.
[0021] The electrodes 6 are conductive self-tapping screws.
[0022] A plurality of conductive self-tapping screws of the water quantity detection device are arranged equidistantly from bottom to top, and are installed on the left side wall of the water tank part 7, and a waterproof seal is arranged between the left side wall of the water tank part 7, the PCB board and the conductive self-tapping screws. In the sealing part, the tail end of the self-tapping screw protrudes out of the cavity of the water t...

The present invention provides a coffee machine, including a water tank component comprising a water level detection apparatus for detecting the level of stored water remaining; and a control apparatus comprising a module for calculating the level of stored water remaining, wherein the water level detection apparatus sends detected information to the module for calculating the level of stored water remaining to calculate a value for the level of stored water remaining. At the same time, the control apparatus comprises a coarse-fine adjustment feedback apparatus, calculating a matching amount of ground coffee powder according to the value for the level of stored water remaining and controlling the operation of a bean-grinding apparatus. The water level detection apparatus comprises a set of electrodes arranged on the side wall of the water tank in the direction of the water level from high to low. The electrodes are used to convert position information about the water level into an electrical signal transmitted to the module for calculating the level of stored water. Using the conductivity of water, the set of conductor electrodes completely or partially conducts and feeds back the information to the control apparatus. The amount of water to be added is calculated by the control apparatus, and according to the amount of water to be added, the control apparatus determines the amount of coffee powder ground by the bean-grinding apparatus to match the amount of water to be added, making the coffee brewing process more accurate and stabilizing the taste produced.
Description
technical field [0001] The invention relates to the technical field of brewing equipment for coffee and similar beverages, in particular to a coffee machine. Background technique [0002] Users have put forward higher requirements for the intelligent features of coffee machine products. The current coffee machine has not been equipped with a device that can detect the remaining water storage in the water tank. Therefore, the control part of the coffee machine cannot adjust the amount of coffee grinding according to the remaining water storage, resulting in inaccurate grinding of coffee, which in turn leads to coffee The volume and concentration produced are not accurate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a coffee machine, which can accurately detect the remaining water storage in the water tank, and then brew coffee and similar beverages with appropriate concentration and good taste. [0004] The ...
