The basket low point detection switch SW2 is turned on in the basket lowering mode to electrically connect the basket lowering loop circuit, and when the lower basket 45 is detected, the basket lower point detecting switch SW2 is electrically disconnected to cut off the basket lowering loop circuit. Stop descent of).

The basket high point detection switch SW5 is turned on when the basket rising mode is connected, and electrically connects the basket rising loop circuit, and when the lower basket 45 is detected, the basket high point detecting switch SW5 electrically cuts off the basket rising loop circuit to lower the basket. Stop the rise of).

The freezer upper right basket open detection switch SW4 is turned off when the freezer upper right basket 38 is detected to block the switching to the basket up mode or the basket down mode, that is, the basket up loop circuit or the basket down loop. The circuit is interrupted to stop the rising or lowering operation of the lower basket 45.

The freezer compartment upper left basket open detection switch SW3 is turned off when the freezer upper left basket 38 is detected to block the switching to the basket ascending mode or the basket descending mode, that is, the basket ascending loop circuit or the basket descending. The loop circuit is cut off to stop the rising or lowering operation of the lower basket 45.

The freezer compartment door open detection switch SW7 is turned off when the refrigerating compartment door is closed, and is turned on when the refrigerating compartment door is opened to electrically connect the basket ascending loop circuit or the basket descending loop circuit in the basket ascending mode.

Each of the first and second relays RY1 and RY2 includes two relays interlocked with each other to electrically connect the basket lowering loop circuit or the basket upper loop circuit.

The operation of the embodiment of the movement control apparatus of the refrigerator having the basket lift function of the present invention configured as described above will be described.

First, when the user opens the refrigerator door, the refrigerator door open detection switch SW7 is turned on and waits to electrically connect the basket up loop circuit. In this case, when the user selects the basket up mode with the mode selection switch SW6, The power is supplied to the relay RY1 by the mode selection switch SW6 to electrically connect the basket rising loop circuit.

That is, through the first relay RY1 and the second relay RY2, the upper right basket open detection switch SW4 and the freezer upper left basket open detection switch SW3, the basket high point detection switch SW5, and the emergency switch. (SW1) is electrically connected.

Accordingly, the lower basket 45 is automatically raised, and when the basket high point detection switch SW5 detects the lower basket 45, the basket high point detection switch SW5 is turned off to lower the basket 45. Stops the rise, thereby stopping the lower basket 45 at a predetermined position.

In addition, when the user selects the emergency switch SW1 in an emergency, the emergency switch SW1 electrically interrupts the rising loop circuit to stop the lifting operation of the lower basket 45.

If the lower basket 45 rises to a high point, when the refrigerating compartment door open detection switch SW7 detects the closing operation of the refrigerating compartment door, the refrigerator is turned off, and the first and second relays RY1 and RY2 are turned off. By cutting the current flowing in the), thereby automatically switching the current mode to the basket lowering mode to lower the lower basket (45).

In this state, when the user selects the basket lowering mode with the mode selector switch SW6, the current flowing through the first and second relays RY1 and RY2 is blocked by the mode selector switch SW6, and the basket lowering loop circuit Is electrically connected.

That is, through the first relay RY1 and the second relay RY2, the upper right basket open detection switch SW4 and the freezer upper left basket open detection switch SW3, the basket low point detection switch SW2, and the emergency switch. (SW1) is electrically connected.

Accordingly, the lower basket 45 descends, and when the basket low point detection switch SW5 detects the lower basket 45, the lower basket 45 is turned off to stop the lowering operation of the basket 45, thereby lowering the basket 45. ) Back to its original position.

In other words, the present invention, when the food is to be stored and / or withdrawn inside the basket provided on the back of the lower door of the refrigerator, the basket is automatically raised or lowered by a simple switch-pressing operation of the user to the desired position When the lower basket is raised to a high point, the refrigerator door open detection switch is turned off when the refrigerator door is closed, and cuts off the current flowing to the first and second relays. As a result, the current mode is automatically switched to the basket lowering mode to lower the lower basket.

The specific embodiments or examples made in the detailed description of the present invention are intended to clarify the technical contents of the present invention to the extent that they should not be construed as limited to these specific embodiments and should not be construed in consultation. Various changes can be made within the scope of.

As described in detail above, in the present invention, when the food is to be stored and / or withdrawn from the inside of the basket provided on the rear door of the refrigerator, the basket is automatically lifted or lifted by a simple switch-pressing operation of the user. By automatically descending to a desired position, there is an effect of improving the convenience of the user.

In addition, when the lower basket is raised to the high point, the refrigerating compartment door open detection switch is turned off when detecting the closing of the refrigerating compartment door, to cut off the current flowing to the first and second relay, thereby automatically the current mode By lowering the lower basket by switching to the basket lowering mode, there is an effect of improving the convenience of the user.

In addition, by providing an emergency switch, by stopping the lifting or lowering operation of the lower basket in the emergency, there is an effect of improving the stability of the system.
