Abstract
The utility model discloses a dynamic and negative-light slow stewpot, which provides a slow stewpot which utilizes a backlight lamp with various colors to express the working state. The utility model comprises a pot body and is also provided with an LCD backlight lamp with two colors, a transistor switching circuit and an SCM, wherein one end of the LCD backlight lamp is connected with a power supply, and the other end is connected with an output end of the transistor switching circuit; an input end of the transistor switching circuit is connected with the SCM.
Description
Technical field
The utility model relates to a kind of slow cooker, is meant the dynamic backlight slow cooker especially.
Background technology
At present, the slow cooker that popular on the market band LCD shows is backlight mainly to be no backlight or monochromatic backlight, and its shortcoming is that the duty of slow cooker is clear inadequately, makes troubles to the user.
The utility model content
Technical problem to be solved in the utility model is to propose the slow cooker that a kind of backlight that utilizes different colours is represented duty.
Technical scheme provided by the utility model is: it comprises a pot body, it is characterized in that: it also is provided with LCD backlight, transistor switching circuit, the single-chip microcomputer of two kinds of colors, wherein, one end of LCD backlight is connected with power supply, the other end is connected with the transistor switching circuit output, and the transistor switching circuit input is connected with single-chip microcomputer.
Described single-chip microcomputer adopts the single-chip microcomputer of HT46R47 model.
The utility model has following advantage: the user comes into plain view to duties such as the standby of slow cooker, heating, insulations.
