First, the principle of ergonomics. Pay attention to ergonomics when using. When cooking in the kitchen, you must bend over for a long time. Only by proper design can you avoid the problem of backache. For example, when the height of the countertop of kitchen utensils is15cm from the wrist when working on the countertop, it is most suitable for people to engage in easier cooking. The height of the closet and shelf is 170 to 180 cm, which is suitable for people to reach out and get. The cabinet space beyond this height can store uncommon items. The distance between the upper and lower cabinets is 55 cm. Except for the I-shaped kitchen, in other forms of kitchens, a triangular workspace will be formed between the refrigerator, the workbench and the stove, and the distance between the three sides must be more than 60 to 90 cm, so that users will not be too close or too far when taking and placing food, and will not be too embarrassed when turning around.

Second, space determines the form. Depending on the size of the space, the kitchen can be divided into straight type, L type, concave type and island type.

The linear structure of a straight-line kitchen is simple and clear, and usually requires a space of 7 square meters and a length of 2 meters. As long as the cooking equipment is placed from left to right or from right to left according to the user's habits. If space conditions permit, part of the wall of the space adjacent to the kitchen can also be knocked out and changed into a low cabinet in the form of a bar, so that a semi-open space can be formed and the use area can be increased.

The two sides of the L-shaped kitchen should be at least 1.5 meters long, which is characterized by placing all the equipment on the two axes of the L-shaped kitchen according to the cooking order. However, in order to avoid the inconvenience caused by too close fire and water, it is best to put the refrigerator and sink side by side in a straight line, while the stove is placed on the other axis. If you want to be more convenient in cooking, you can install a locker on the side of the L-shaped corner against the wall, which can not only increase the capacity of collecting items, but also occupy no plane space; You can also continue to extend on the axis of the L-shape, and design a foldable or pull-out table top, which can be put away when not in use at ordinary times and opened for use after cooking for a long time.

If you add another cupboard in the L-shaped kitchen, it will become a concave font. Concave kitchen can plan more advanced cabinets at the corner and left and right sides to increase the storage function. The concave shape has two corner spaces, which is often overlooked by people. In fact, it can be equipped with a corner rotating cabinet that can rotate 180 or 360 degrees. When the door is opened, the items placed inside will rotate out.

Nakajima kitchen is to add an independent table in the center of the kitchen, which can be used as a pre-meal preparation area and also serve as a dining table, but it needs at least 16 square meters of space.
