Abstract
An improved dishwashing machine is proposed which has a dish-cleaning compartment, a dish-rack rotating mechanism, a re-circulating fluid spraying system, a non re-circulating fluid spraying system, a drainage mechanism, a waste filter tank and a controlling means. The dish-cleaning compartment includes a cover and a casing, which includes a re-circulating fluid spray arm and a non re-circulating fluid spray arm. Automatic chemical dispenser, hot air dish-drying system and ultraviolet light sterilizer are included as optional features. Dish-cleaning operation starts with a flush cycle and then follows by a wash cycle and a rinse cycle. A dish-drying operation is introduced at the end of the rinse cycle, to dry as well as to sanitize dishes.
Claims18
A single chamber dishwashing machine comprising:
- a dish-cleaning compartment having a cover and a casing;
- a re-circulating fluid spraying system wherein a re-circulating fluid is delivered to a re-circulating fluid spray arm;
- a non re-circulating fluid spraying system wherein a non re-circulating fluid is delivered to a non re-circulating fluid spray arm;
- a dish-rack rotating mechanism and drive for rotating a dish-rack holder and a dish-rack;
- a drainage mechanism for chanelling a used flush fluid, a used wash fluid or a used rinse fluid from the dish-cleaning compartment to a designated drain location;
- and
- a controlling means for controlling a dishwashing machine operation.
A method for cleaning a dish comprising the steps of:
- (i) providing a single chamber dishwashing machine having a dish-cleaning compartment having a cover and a casing;
- a re-circulating fluid spraying system wherein a re-circulating fluid is delivered to a re-circulating fluid spray arm;
- a non re-circulating fluid spraying system wherein a non re-circulating fluid is delivered to a non re-circulating fluid spray arm;
- a dish-rack rotating mechanism and drive for rotating a dish-rack holder and a dish-rack;
- a drainage mechanism for chanelling a used flush fluid, a used wash fluid or a used rinse fluid from the dish-cleaning compartment to a designated drain location;
- and a controlling means for controlling a dishwashing machine operation;
- (ii) transferring a loaded dish-rack to the rotating dish-rack holder at the dish-cleaning compartment;
- (iii) rotating the loaded dish-rack together with the dish-rack holder by the dish-rack rotating mechanism and drive;
- (iv) flushing the loaded dish-rack in the dish-cleaning compartment using the non re-circulating fluid spray arm;
- (v) washing the loaded dish-rack in the dish-cleaning compartment using the re-circulating fluid spray arm;
- and
- (vi) rinsing the loaded dish-rack in the dish-cleaning compartment using the non re-circulating fluid spray arm.
