On the other hand, among the dishwashers there is a dishwasher configured to hide the display in the interior of the door when the display is provided on the inner top of the door to close the door.

As such, since the dishwasher provided with the display on the top of the door is configured to not know the operation state through the display while the door is closed and operated, unnecessary power is consumed for the operation of the display.

The present invention has been made to solve the problems of the prior art, to provide a display power saving method of the dishwasher to reduce the power consumption of the dishwasher to reduce the power consumption of the dishwasher.

The configuration of the display power saving method of the dishwasher according to the present invention comprises the steps of recognizing the closing of the door to cut off the power supply to the display; And recognizing the opening of the door to supply power to the display.

Here, the display is installed to be concealed when the door is closed.

In addition, a limit switch is installed in the door, and power supply to the display side is cut off by the limit switch.

In addition, the door may be equipped with an infrared sensor that operates in the closed state, the power supply to the display can be resumed by the detection of the human body by the infrared sensor.

In addition, the door is rotatably installed at the bottom of the cabinet, the door is rotated downward to supply power to the display.

On the other hand, the door is rotatably installed in the lower portion of the cabinet, the power supply to the display can be cut off as the door is rotated upwards.

In the display power saving method of the dishwasher according to the present invention as described above, when the door is closed for the display of the dishwasher with the display hidden structure, the power consumption of the display by blocking the power supply to the display side that cannot be seen from the outside By reducing the power consumption of the dishwasher can be reduced.

Hereinafter, a preferred embodiment of the display power saving method of the dishwasher according to the present invention will be described with reference to the accompanying drawings. In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout the specification.

In addition, the following examples are not intended to limit the scope of the invention, but merely illustrative of the components set forth in the claims of the present invention, which are included in the technical spirit throughout the specification of the present invention and components of the claims Embodiments including substitutable components as equivalents in may be included in the scope of the present invention.

Example

1 is a flowchart illustrating a display power saving method of the dishwasher according to an embodiment of the present invention, Figure 2 is a display of the dishwasher equipped with a display power saving method of the dishwasher according to an embodiment of the present invention. Perspective view.

1 and 2, the display power saving method of the dishwasher according to an embodiment of the present invention step (S1) of recognizing the closing of the door 110, the display 120 by recognizing the closing of the door Step (S2) of shutting off the power supply to the step (S2), recognizing the opening of the door 110 (S3), and recognizing the opening of the door 110 to supply power to the display 120 (S4). It includes.

The dishwasher displays the operating state through the display 120 while the power is supplied. Display 120 is a panel that displays letters or pictures in LED (LED) or LED (LED), when the button corresponding to each function is pressed, the cleaning mode (Strong, Medium, Soft), the detergent input (Rinse Aid) Displays the operating nozzles (upper, lower) and operating time of the spray nozzle.

Here, the display 120 is installed to be concealed so that it is not visible from the outside when the door 110 is closed.

When the user closes the door 110, the display 120 is hidden from the outside and the power is cut off. In addition, when the door 110 is opened, the display 120 is exposed to the outside and the power is supplied, and the user presses a function button and checks the setting state through the display 120.

In addition, the limit switch 122 is installed in the door 110, and the power supply to the display 120 can be cut off by the limit switch 122. When the door 110 is closed, the limit switch 122 is operated to be in an on state, and the closing of the door 110 may be detected by the controller 125 being in the on state of the limit switch 122. In this case, the controller 125 cuts off power to the display 120 to prevent power consumption from the display 120. In addition, the control unit 125, when the door 110 is opened, the limit switch 122 is turned off, detects the opening of the door 110 to supply power to the display 120 side through the display 120 Display the setting status of the dishwasher.

On the other hand, when the display 120 is exposed to the outside while the door 110 is closed, the user can know the remaining operating time of the dishwasher and the operation stage of the dishwasher through the display 120.
