The work triangle
The work triangle is a tool used in determining the
appropriateness of a particular kitchen design. It is constructed by
connecting up the central points of the sink, the hob, and the refrigerator
so they form a triangle. Then we determine the circumference of that
triangle, which gives us the total work distance in the kitchen. As a rule
of thumb, the total distance between sink, hob and refrigerator should be
somewhere within 3600-6600 mm. The distance between sink and hob should be
1200-2000 mm. And the work triangle as such should not be crossed by any
line of traffic.
Linear kitchen
Linear kitchen design is unsuitable for wheelchair users, as
the distances between workstations are too great. This kitchen model is not
practical when several persons need to work there at the same time. The
linear kitchen is often chosen where the available space is small, and when
the kitchen does not have a very high priority - for example in sheltered
housing where food is delivered or where food is eaten in a communal dining
room.
Double linear (parallel) kitchen
This design is not suitable for wheelchair users and the
walking-impaired because food and cooking utensils must be moved from one
working top to the other. The double linear kitchen is often used where the
kitchen has a door at both ends, and is not recommended for anyone with a
physical disability. Kitchen designs with islands should also be avoided.
The L-shape
The L-shaped kitchen is suitable for both wheelchair users
and for those who have difficulty walking, because the triangular
arrangement provides continuity between the individual workstations. Food
and cooking utensils can be moved across the countertop, thus avoiding
lifting. The L-shaped design is used, for example, in large kitchens where
more than one person may be working in the kitchen at once.
The U-shape
The U-shaped kitchen provides good connectivity where there
is a need for extra workstations. This arrangement shortens distances and
concentrates workstations. The food and cooking utensils can be drawn across
the counter to avoid lifting. The U-shaped installation is used, for
example, in large kitchens where more than one person may be working in the
kitchen at once.
