LIQUID SENSING DEVICE, DETERGENT FEEDING DEVICE AND WASHING MACHINE HAVING THE SAME

摘要

The present invention relates to a detergent feeding device and a washing machine having the same and, more specifically, to a device to input detergent by supplying power to the detergent feeding device. One aspect of the present invention provides a washing machine characterized by including a cabinet, a tub arranged inside the cabinet, and a detergent feeding device feeding detergent to the tub. The detergent feeding device includes: a detergent box receiving housing unit installed inside the cabinet and includes an opening on the front of the cabinet; a detergent box which receives the detergent and is mounted to be separated from the detergent box receiving housing unit through the opening formed on the detergent box receiving housing unit; a pump unit installed on the outer side of the detergent box and pumps the detergent to the detergent box receiving housing unit; a first body which supplies power to the pump unit and is mounted on the outer side of the pump unit; a second body mounted on the detergent box receiving housing unit; and a connector unit electrically connected to the first and second bodies by attaching and detaching the first and second bodies. The present invention can prevent a bad electrical connection of the detergent box by preventing the detergent box from being shaken with the connector unit of a detergent inputting device and can sense that the detergent box is received in the detergent box receiving housing unit. Furthermore, the present invention can prevent the intake of moisture to the connector unit through the structure of the connector unit.
