Dish washing machine

A dish washing machine for spraying water on dishes contained in a cavity having a washing process for washing the dishes in the cavity and a rinsing process for rinsing the dishes in the cavity, each washing process and rinsing process having a drainage process for draining wash water in the cavity, comprising:

• storing means storing a first sequence having a first drainage operation and a second sequence having a second drainage operation, the first drainage operation being different from the second drainage operation;
• means for outputting a signal representing a degree of dirt on the dishes;
• and
• control means for controlling the drainage processes in the washing process and the rinsing process on the basis of the first sequence stored in the storing means in response to the application of a signal indicating that the degree of dirt on the dishes is relatively high from the outputting means, while controlling drainage processes in the washing process and the rinsing process on the basis of the second sequence stored in the storing means in response to the application of a signal indicating that the degree of dirt on the dishes is relatively low from the outputting means.

A dish washing machine, comprising:

• a cavity for containing the dishes;
• water supplying means for supplying wash water to said cavity;
• a nozzle for spraying the wash water on the dishes;
• water feeding means for feeding into said nozzle the wash water supplied to said cavity to spray the wash water from said nozzle;
• water draining means for draining the wash water outward from said cavity;
• storing means storing a first sequence in which particular operations are included corresponding to a case where a degree of dirt on the dishes is relatively high and a second sequence in which the particular operations are omitted corresponding to a case where the degree of dirt on the dishes is relatively low;
• means for outputting a signal representing the degree of dirt on the dishes;
• and
• control means for controlling the driving of said water supplying means and said water draining means on the basis of the first sequence, in which particular operations are included stored, in said storing means in response to the application of a signal indicating that the degree of dirt on the dishes is relatively high from said outputting means, while controlling the driving of said water supplying means and said water draining means on the basis of the second sequence, in which particular operations are omitted, stored in said storing means in response to the application of a signal indicating that the degree of dirt on the dishes is relatively low from said signal outputting means.
