Title: Sink for kitchen
Inventor: UDO KIMIO
IPC: E03C1/042
Filed: 2001-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a faucet, which is excellent in antifouling properties and cleanability, and a sink for a kitchen, which has great depth. SOLUTION: The sink for the kitchen is composed of a faucet mounting surface which is mounted with a faucet fitting, a bowl part in which water is stored, and a drain inlet for draining. Characteristically, the faucet mounting surface is partially inclined, and a lower end of an inclined plane is made to face the bowl part, so that the depth of the sink can be made greater to an adequate dimension while a surface required for mounting of the faucet fitting is secured. Because the lower end of the inclined plane is made to face the bowl part, e.g. water droplets, which adhere to the inclined plane and into which a detergent is mixed, flow down rapidly onto a bowl surface in order to enhance the cleanability. In addition, verticality relative to the inclined plane enables use of the normal faucet fitting and a fixing part thereof.
