PURPOSE: To obtain improvement in housing capacity and performance of a system kitchen while retaining regularity in appearance and workability on a work top of a sink stand.

CONSTITUTION: A sterilizing cabinet 1 of elevation type which is equipped with a sterilizing lamp and a cooking tool housing part is connected and fixed to a lower part of a cutout 18 of a work top 17 on a sink stand 11 in the vicinity of a sink part. The elevatable sterilizing cabinet 1 has a door of such a shape and a size as can pass through the cutout 18. Thus, cleaned wares can be housed in the sterilizing cabinet 1 so quickly that water drops after cleaning can be prevented from being scattered, and in addition, sterilization by a sterilizing lamp and drying by heat generation can be done at the same time. When it is not used, it can be housed in a lower part below the work top 17 surface of the sink stand 11, whereby appearance of a system kitchen can be improved. Further, when it is used, the strilizing cabinet 1 is made to go up only by operation of a switch. Thus, the housing capacity and performance as a system kitchen can be much improved, and further, workability on the work top of the sink stand can be retained.
