Title: Slow cooker with a touch and slide screen

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to the technical field of slow cooker, and more specifically relates to a slow cooker with a touch and slide screen. 
     A slow cooker is a kind of cooking utensil. It is widely used because food stuff can be heated evenly and the cooked food tastes delicious. A slow cooker generally has heating parts inside an insulating shell. Also, it has a cooking pot (usually a ceramic pot) and a glass cover. A basic cooking principle of the slow cooker is heat conduction. Heat energy produced by the heating parts inside the slow cooker will be slowly and evenly conducted to the cooking pot. Therefore, user is not required to monitor the slow cooker during long hours of cooking. The use of indirect heat source allows the food to be heated up evenly, the food will be cooked and stewed slowly to preserve the original tastes and flavors of the food. A conventional slow cooker has the following disadvantages: firstly, a conventional slow cooker is not equipped with any computer display panel, and so a real-time operating condition of the slow cooker cannot be shown; secondly, a conventional slow cooker only has an on/off switch, and so it is not possible to control the cooking time; this limited function of the slow cooker causes inconvenience and waste of energy during use, and also fails to go green because it cannot choose different cooking hours based on different types of food.
