1, U-type: short operation route and high operation efficiency, which are more common in early house types. Most of them are rectangular kitchens with doors and windows facing each other. Washing, cutting and frying (right-handed habit) can easily realize the triangular workspace and greatly reduce the operation streamline;

2. Island type: It is difficult to realize in China, and it is characterized in that some or all functions of washing, cutting and frying are formed into a guide shape. It can satisfy the cooperation of many people, but it will not affect each other. It can be realized by using Nakajima cart (with locking) and bar;

3. Type G: After the door is opened, it is located in the corner of the kitchen, with more storage areas than the U-type, which makes full use of the space;

4. Parallel type: the kitchen with sliding door (one side may be a doorway or idle) is common and popular this year, which has the advantage of good lighting and ventilation, but the disadvantage is that the storage function is reduced and the triangular workspace cannot be formed.
