Diswasher and controlling method of the same

Abstract

Dishwashers and methods of control for operation of dishwashers are disclosed. The dishwasher can include one or more racks in a washing compartment for placing used dishes having foreign matter, such as food and drink, and unused dishes having relatively little or no foreign matter and varying washing loads. Operation of the dishwasher can include wash, water drain and supply, and rinse cycles. During the cycles, preheating of a steam generator, water draining and supplying, steam supplying, and water spraying can occur and partially or fully overlap. The dishwasher can reduce excessive washing of dishes having small washing loads and improve power and water consumption.

AI Technical Summary

Benefits of technology

[0008]The present disclosure is generally directed to a dishwasher that improves washing efficiency and methods of control and operation of the dishwasher. In some embodiments, used and unused dishes having varying washing loads can be washed in a single washing compartment of the dishwasher.

[0018]According to embodiments of the present disclosure, washing efficiency of the dishwasher may be improved when dishes with different washing loads, such as used and unused dishes, are washed in a single washing compartment. Advantageously, the time taken to wash the dishes can be reduced. In addition, the energy and water consumption of the dishwasher can be reduced.

Problems solved by technology

Unfortunately, the conventional dishwasher is not well-suited for washing unused dishes with used dishes.

For example, it may be an inefficient use of time and energy to wash used dishes, which have a large washing load, with unused dishes, which have a small washing load in the same dishwasher (and in particular, the same washing compartment).
