Bean grinder

Abstract

The embodiment of the invention provides a bean grinder. The bean grinder comprises a grinding mechanism, an operating component and a controller connected with the grinding mechanism and the operating component, the bean grinder provides a first mode and a second mode for a user to select, and the controller is used for responding to selection operation of the user on the second mode and enablingthe user to modify preset first parameters through the operating component; and on the basis of the modified first parameter, the powder discharging speed of the current grinding mechanism under thefineness gear selected by the user is adjusted, wherein the preset first parameter is used for representing the powder discharging speed having a historical association relationship with the finenessgear of the grinding mechanism. According to the bean grinder provided by the embodiment of the invention, in the second mode, the preset powder discharging speed of the grinding mechanism at the corresponding fineness gear can be corrected, so that the actual powder discharging amount is matched with the preset powder discharging amount, the technical problem of inaccurate powder discharging amount caused by abrasion of the grinding mechanism can be solved, and the bean grinder is beneficial to improving the user experience.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of household appliances, and in particular to a bean grinder. Background technique [0002] The grinder is used to grind coffee beans and other food ingredients. When in use, its controller can determine the grinding time according to the powder fineness and powder output selected by the user, and control the grinder to grind the food based on the grinding time, so that the actual output The powder quantity corresponds to the selected powder output. For example, the Chinese invention patent with application publication number CN109106216A discloses a coffee cooking device for office use, which includes a housing, a display screen, and control buttons. There is a grinder, a grinder is arranged in the grinder, a laser sensor is arranged above the grinder, a powder outlet pipe is arranged at the lower end of the grinder, and a cooking box is arranged below the powder outlet pipe. The cof...

Problems solved by technology

However, with the prolongation of the use time, the cutter head of the grinder will wear out, which will cause the gap between the cutter heads to become larger and the powder output speed to become faster. When the grinding time remains the same, the actual powder output will be greater than the selected powder output.
