  • Patent number: 4998302
    Abstract: A highly stable and self-contained mobile hygiene cabinet comprises a housing assembly mounted on a plurality of wheels and a wash basin mounted on a top of the cabinet. First and second tanks are mounted centrally within the cabinet for retaining cold and hot water therein, respectively. A third tank is also mounted in the cabinet, below the other tanks, and communicates with the basin to receive waste waters therefrom. Water dispensing apparatus, including a manually actuated handle knob and a sprayer attachment, are mounted on the cabinet adjacent to the basin for receiving and dispensing water. A water supply control system selectively communicates cold, hot or a mixture of cold and hot water from one or both of the first and second tanks to the water dispensing means. An electrical control system is provided for selectively driving pumps to effect such communication and to also purge the third tank of waste water.
