CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a U.S. National Stage Application which claims the benefit under 35 U.S.C. § 371 of International Patent Application No. PCT/KR2017/012072 filed on Oct. 30, 2017, which claims foreign priority benefit under 35 U.S.C. § 119 of Korean Patent Application No. 10-2017-0000918 filed on Jan. 3, 2017 in the Korean Intellectual Property Office, the contents of both of which are incorporated herein by reference.

TECHNICAL FIELD

Embodiments of the disclosure relate to a dish washing machine capable of shortening the time for washing by selectively cleaning an area in which dishes are placed, and a method of controlling the same.

BACKGROUND ART

A dish washing machine includes a main body provided with a washing tub therein, a basket for accommodating dishes, a sump for storing washing water, a nozzle for spraying the washing water, and a circulation pump for supplying the washing water in the sump to the nozzle. The dish washing machine is a household appliance that washes dishes by spraying high pressure washing water to the dishes.

In order to quickly perform processes such as washing and rinsing, an area in which dishes are accommodated and an area in which dishes are not accommodated need to be distinguished such that the processes such as the washing and the rinsing are performed in the area in which the dishes are accommodated. However, in the conventional dish washing machines, washing, rinsing, and the like are performed even on an area in which dishes are not accommodated, and are also performed without sensing the position in which dishes are accommodated by only sensing the accommodation of the dishes, which increases the washing time and decreases the washing power. Accordingly, it is required to perform an appropriate operation to solve the problem.

DISCLOSURE

Technical Problem

Therefore, it is an aspect of the disclosure to provide a dish washing machine for sensing an area in which dishes are accommodated and supplying washing water to the area in which the dishes are accommodated, and a method of controlling the same.

Technical Solution

In accordance with an aspect of the disclosure, a dish washing machine may include a door configured to being attached to a door identifier; a main body in which a washing tub for opening and closing a front opening of the door is provided; a basket configured to be installed in the washing tub to be able to be inserted into or drawn out of the washing tub and contain dishes and have a basket identifier; a sensing unit configured to sense the basket identifier and the door identifier; a plurality of nozzles for spraying washing water; a vane configured to reflect the sprayed washing water in the washing tub; a driving unit configured to drive the vane; and a controller configured to control the driving unit such that cleaning is performed for each dish storage area of the basket based on the sensed result of the sensing unit, wherein the controller may determine the area where the dishes are laid, and controls the driving unit to clean the dish storage area where the dishes were laid.

Further, the basket identifier and the door identifier each may include a color or a pattern distinguished by the controller.

Further, the basket identifier may be provided in front of the basket, and the door identifier may be provided on an inner side surface of the door.

Further, the sensing unit may include a camera provided at an upper end of the main body to take pictures of the front of the main body, and the controller may generate position information of the basket identifier and a portion of the door identifier that are overlapped with each other based on the detected result of the sensing unit, the position information of the portion of the door identifier that is overlapped may include an x-coordinate from one end of the door to the portion of the door identifier that is overlapped, the position information of the basket identifier may include a y-coordinate indicating a distance from the front opening of the washing tub to the basket identifier, and the position information of the door identifier may include width information of the overlapped portion of the door identifier.

Further, the controller may determine a plurality of the dish storage areas where the dishes are laid.

Further, the dish washing machine may further include a sump configured to store the washing water; and a dispensing device configured to supply the washing water stored in the sump to the plurality of nozzles, and the driving unit may activate the dispensing device according to a control signal of the controller, and the controller may control the driving unit such that the nozzle corresponding to the dish storage area where the dishes are laid among the plurality of nozzles sprays the washing water to the dish storage area where the dishes are laid.

Further, the plurality of nozzles may be fixed to a lower side of the washing tub, and the vane may perform a linear reciprocating motion along the spraying direction of the plurality of nozzles by driving the driving unit.

In accordance with an aspect of the disclosure, a method for controlling a dish washing machine comprising a plurality of nozzles, a vane for reflecting washing water sprayed from the plurality of nozzles, and a driving unit for driving the vane, the method may include detecting a basket identifier attached to a basket for storing dishes; detecting a door identifier attached to a door; and controlling the driving unit to perform cleaning for each dish storage area of the basket based on the detection result of the detecting step, and the step of controlling the driving unit may include the steps of determining the dish storage area in which the dishes are stored and controlling the driving unit to clean the dish storage area in which the dishes are stored.

Further, the step of determining the dish storage area in which the dishes are stored may include generating position information of the basket identifier and a portion of the door identifier that are overlapped with each other based on the detected result, and the position information of the portion of the door identifier that is overlapped may include an x-coordinate from one end of the door to the portion of the door identifier that is overlapped, the position information of the basket identifier may include a y-coordinate indicating a distance from the front opening of the washing tub to the basket identifier, and the position information of the door identifier may include width information of the overlapped portion of the door identifier.

Further, the basket may include an upper basket and a lower basket, and before the step of detecting the door identifier, the method may determine whether the upper basket is taken out or pushed in based on the detection result of the basket identifier of the upper basket, and may determine whether the lower basket is carried out or carried in based on the result of detection of the basket identifier of the lower basket.

Further, before the step of detecting the door identifier, the method may further determine that the basket is carried in, and the basket identifier and the door identifier each may include a color or a pattern distinguished from each other.

Further, the dish washing machine may further include a dispensing device configured to supply the washing water stored to the plurality of nozzles, and controlling the driving unit to perform cleaning for each of the dish storage areas of the basket based on the detection result of the detecting step may include controlling the driving unit to activate the dispensing device such that the nozzle corresponding to the dish storage area where the dishes are laid among the plurality of nozzles sprays the washing water to the dish storage area where the dishes are laid and supplying the washing water by driving the dispensing device to the dish storage area where the dishes are laid by the driving unit.

Further, the dish washing machine may further include a camera provided at an upper end of the main body to take pictures of the front of the main body, and detecting the basket identifier may include detecting the basket identifier by the camera; and detecting the door identifier may include detecting the door identifier by the camera.

Advantageous Effects

As is apparent from the above description, as the washing water is supplied intensively to the area in which the dishes are placed, the washing power of the dishes can be increased.

Also, as is apparent from the above description, as the washing water is selectively supplied to the area in which the dishes are stored, the execution time of the process such as washing or rinsing can be shortened.
