Hereinafter, with reference to the accompanying drawings, the operation and effect of the movement control apparatus of the refrigerator having a basket lift function according to the present invention.

3 is a perspective view of a refrigerator provided with a basket lift function to which the present invention is applied.

As shown in Fig. 3, a main body 11 having a lower cooling chamber 31 having a front surface opened therein; A lower door 41 that opens and closes the front opening of the lower cooling chamber 31 while sliding along the front and rear directions of the main body 11; A basket 45 which is integrally slid with the lower door 41 on the rear side of the lower door 41 and is arranged to be liftable with respect to the lower door 41; a basket ascending mode or basket descending by a user's selection And a basket movement control means (not shown) for selecting a mode and controlling the basket 45 to be raised or lowered automatically according to the selection result.

As shown in Fig. 4, the basket movement control means includes: a mode selection switch SW6 selected by the user to select the basket up mode or the basket down mode; A relay RY which is electrically switched by the switching operation of the mode selection switch SW6 to provide an electrical circuit for the basket up mode or the basket down mode; A basket low point detection switch SW5 for detecting a low point position of the basket 45 in the basket lowering mode; A basket high point detection switch SW1 for detecting a high point position of the basket 45 in the basket raising mode; A freezer compartment upper right basket open detection switch (SW3) for detecting the opening of the upper right basket of the freezer compartment in the basket raising mode; A freezer compartment upper left basket open detection switch (SW2) for detecting an opening of the upper left basket of the freezer compartment in the basket raising mode; Refrigerating chamber door opening detection switch (SW4) for detecting the opening of the freezer door.

The relay RY includes first and second relays interlocked with each other, and the mode selection switch SW6 also includes first and second switches interlocked with each other.

The basket low point detection switch SW5 is turned on when the basket lowering mode is connected to electrically connect the basket lowering loop circuit, and when the basket 45 is detected, the basket lower point detecting switch SW5 is electrically disconnected to block the basket lowering loop circuit to lower the basket 45. To stop.

The basket high point detection switch (SW1), in the basket rising mode, is turned on and electrically connected to the basket rising loop circuit, when the basket 45 is detected, it is off to electrically cut off the basket rising loop circuit of the basket 45 Stop the ascent.

The freezer upper right basket open detection switch SW3 is turned off when the freezer upper right basket is opened to block the switching of the basket lift mode, that is, the basket lift loop circuit is blocked to lift the basket 45. Stop it.

The upper left basket open detection switch SW2 of the freezer compartment is turned off when an open of the upper left basket is detected to block the switching to the basket ascending mode, that is, to block the basket rising loop circuit, thereby raising the basket 45. To stop.

The freezer compartment door open detection switch SW4 is turned off when the refrigerating compartment door is closed and turned on when the refrigerating compartment door is opened to electrically connect the basket ascent loop circuit in the basket ascending mode.

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 SW4 is turned on and waits to electrically connect the basket up loop circuit, and when the user selects the basket up mode with the mode selection switch SW6, The power is supplied to the relay RY by the mode selection switch SW6 to electrically connect the basket rising loop circuit.

That is, the basket high point detection switch (SW1), the freezer compartment upper right basket open detection switch (SW3), the freezer compartment upper left basket open detection switch (SW2) and the refrigerator compartment door open detection switch (SW4) is electrically connected.

Accordingly, when the basket 45 is automatically raised, and the basket high point detection switch SW1 detects the basket 45, the basket high point detection switch SW1 is turned off to stop the basket 45 from rising. Thus, the basket 45 is stopped at a predetermined position.

At this time, the upper right basket open detection switch (SW3) and the upper left basket open detection switch (SW2) and the freezer door open detection switch (SW4) of the freezer compartment should be operated at the same time, if the freezer upper right basket open detection switch (SW3) And when any one of the freezer compartment upper left basket open detection switch SW2 and the refrigerator compartment door open detection switch SW4 is turned off.

In this state, when the user selects the basket lowering mode by pressing the mode selection switch SW6, the current flowing through the relay RY is cut off by the mode selection switch SW6 so that the basket up loop circuit is electrically connected.

That is, the mode selection switch SW6, the basket low point detection switch SW5, and the relay RY are electrically connected to each other.

Accordingly, the basket 45 is lowered, and when the basket low point detection switch SW5 detects the basket 45, the basket 45 is turned off to stop the lowering operation of the basket 45, thereby reducing the original operation of the basket 45. Return to 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 It is to lower automatically.
