Dishwashing machine

Abstract

A dish washing machine includes the following elements: a main body; a washing tank; a tableware basket for holding target objects to be washed; a washing device for spraying washing water onto the target objects; an atomizer for atomizing the washing water; a door; a detergent automatic insertion device; and a controller for performing at least a pre-washing step, an atomizing step, and a washing step. After the pre-washing step, the controller causes the detergent automatic insertion device to supply detergent to the atomizer, and controls and performs the atomizing step and the washing step. Thus, after the pre-washing step, the step of atomizing a detergent solution can be performed. This enables the dish washing machine to reduce the amount of detergent to be used and to exert high washing performance through the step of atomizing the detergent solution at the same time.

1 . A dish washing machine comprising:
 a main body;   a washing tank;   a tableware basket for holding a target object to be washed;   a washing device for spraying washing water onto the target object to be washed;   an atomizer, provided in a bottom portion of the washing tank, for atomizing the washing water;   a door for opening and closing a front face of the main body;   a detergent automatic insertion device provided above the atomizer and inside the door; and   a controller for performing at least a pre-washing step, an atomizing step, and a washing step,   wherein, after performing the pre-washing step, the controller causes the detergent automatic insertion device to supply detergent to the atomizer.   
     
     
         2 . The dish washing machine of  claim 1 , further comprising a detergent guiding path, provided on the door, for guiding the detergent supplied from the detergent automatic insertion device to the atomizer. 
     
     
         3 . The dish washing machine of  claim 1 , further comprising a detergent guiding path, provided on the tableware basket, for guiding the detergent supplied from the detergent automatic insertion device to the atomizer. 
     
     
         4 . The dish washing machine of  claim 1 , wherein the door includes an upper door openable upward and a lower door openable downward, and the detergent automatic insertion device is provided on the lower door. 
     
     
         5 . The dish washing machine of  claim 2 , wherein the detergent guiding path is provided detachably. 
     
     
         6 . The dish washing machine of  claim 3 , wherein the detergent guiding path is configured to be washable in a rinsing step. 
     
     
         7 . The dish washing machine of  claim 3 , wherein the detergent guiding path is provided detachably.
