One complete freezer drawer is constituted by the first drawer mechanism and the second drawer mechanism.When the first drawer mechanism and Second drawer mechanism it is fully mated at a freezer drawer that do not pull open when, the first drawer-bottom board of the first drawer shell is located at second Between drawer-bottom board and the first support plate；There is second drawer-bottom board the one end on top to be in contact with the first drawer riser, at this time Second guide block is located at the top of the second guide groove, and the second guide block spring is in tensional state, the top of the second drawer-bottom board top end Inclined-plane is bonded by top end by top inclined-plane with slide damper, the top cambered surface and slide damper of the second drawer-bottom board top end One complete smooth cambered surface is constituted by top cambered surface by top end；The lower surface of second drawer-bottom board and the first bottom of drawer The upper surface of plate fits；The upper surface of first support plate and the lower surface of the first drawer-bottom board fit；Second friction pulley with Corresponding fricting strip phase frictional fit on first drawer-bottom board.

When the freezer drawer of the present invention needs to place the drawer slot in refrigerator, freezer drawer of the invention is in and does not pull open Freezer drawer state.First, traditional freezer drawer in conventional refrigerator is taken out from drawer slot, then by the cold of the present invention Freeze drawer to need to place in the drawer slot in refrigerator.

When refrigerated item inside the freezer drawer of the present invention need not be taken out, refrigerator doors are in closed state；At this time Hand is with bottom mounting plate at parastate, and the line and bottom mounting plate at two oval ends of elliptic wheel are at plumbness；First guide block Spring is uncompressed, and the one end of positive stop strip far from elliptic wheel is not inserted into the gap of two neighboring banking stop.First friction pulley with The kerve face phase frictional fit of drawer slot in refrigerator.

When refrigerated item inside the freezer drawer of the present invention needs to take out, user opens refrigerator, then pull handle It is moved to the direction far from square type shell, drives square type shell to be moved to the direction far from the first drawer shell hand channel first rotating shaft, bottom The structure installed on mounting plate and bottom mounting plate follows square type shell to move, and side shield and the second drawer-bottom board follow square type shell to transport It is dynamic.During there is the second drawer-bottom board the one end on top to be moved to separate first drawer riser, the second drawer-bottom board top The top inclined-plane at end no longer squeezes slide damper by top by top inclined-plane, then in the reset response of the second guide block spring Under, the second guide block drives slide damper to move reset to the direction of the second drawer-bottom board, until the second guide block spring is restored to certainly Right state, slide damper are in contact by top with the first drawer-bottom board.Line due to two oval ends of elliptic wheel and bottom For mounting plate at plumbness, the first guide block spring is uncompressed, and the one end of positive stop strip far from elliptic wheel is not inserted into two neighboring limit In the gap of bit slice；So positive stop strip can not be to the rotary stopper of ring set, and then the first friction pulley can drive the second friction pulley Rotation.When the pull-out of bottom mounting plate and into the direction moving process far from the first drawer shell, the first friction pulley and drawer in refrigerator The kerve face of slot, which mutually rubs, generates rolling, and the first friction pulley rotates clockwise, and the first friction pulley drives the second friction pulley counterclockwise Rotation, the second friction pulley drive the first drawer shell to the direction far from square type shell by the frictional fit with fricting strip, fricting strip It is mobile.

Square type shell drive the second drawer-bottom board, side shield, on bottom mounting plate and bottom mounting plate institute's mounting structure to separate When the direction movement of the first drawer shell, installed on square type shell, the second drawer-bottom board, side shield, bottom mounting plate and bottom mounting plate Structure drawer slot from refrigerator pulls out；Since the first friction pulley drives the first drawer shell to separate through the second friction pulley and fricting strip The direction of square type shell is moved, so will appear the first drawer shell and square type shell moves opposite situation；Due to square type shell and first The movement speed of drawer shell is determined by the first friction pulley, so the movement speed of square type shell and the first drawer shell is identical；Also It is to say, institute's mounting structure drawer slot from refrigerator on square type shell, the second drawer-bottom board, side shield, bottom mounting plate and bottom mounting plate When to pull out speed be V, the first drawer-bottom board of the first drawer shell is between the second drawer-bottom board and the first support plate to far from square The direction of shell is moved, and the relative velocity of the first drawer-bottom board relative moment shell is also V, and such first drawer shell phase is for square type Shell moves, and the first drawer shell phase is static for drawer slot in refrigerator.

User by the second drawer-bottom board refrigerated item pull-out take when, close to the second drawer-bottom board cold air and The cold air carried between refrigerated item can be drawn out, and the cold sky of the cold air and the second drawer-bottom board high level at slide damper Gas is not easy to be pulled out；That is, the freezer drawer of the present invention is when needing to take refrigerated item, it is only necessary to by the second drawer Bottom plate pulls out just, and all cold airs in such freezer drawer will not be entirely due to the second drawer-bottom board be pulled out and emerged to ice Outside case, after the second drawer-bottom board places original position, maintaining the temperature in freezer drawer as possible will not rise too high.It is compared to The freezer drawer of traditional refrigerator, traditional freezer drawer are generally required freezer drawer substantially completely when taking refrigerated item It pulls out the refrigerated item placed in freezer drawer could be taken out, but after freezer drawer is substantially completely pulled out, quilt The most cold airs substantially completely pulled out in the freezer drawer come are easy to be brought out；When freezer drawer promotes again After going, most of cold air in freezer drawer is emerged, and the temperature in freezer drawer can be higher than the minimum temperature of refrigerator setting； In order to maintain the low temperature in refrigerator, so needing to start refrigeration system to cool down；When freezer drawer needs frequently repeatedly pull out Come when taking refrigerated item, it is excessively high that the temperature rises in jelly drawer, then refrigerator will continually freeze, this adds increased the work(of refrigerator Consumption.And the freezer drawer of the present invention only has part cold air that can emerge when taking refrigerated item, in freezer drawer, relatively reduces The cold air to come up in freezer drawer, especially when frequently repeatedly pulling out to take refrigerated item, the temperature in freezer drawer It is excessively high to make in freezer drawer that the temperature rises because of refrigerated item is frequently taken, and such refrigerator would not continually freeze, and It is only just run when needing refrigeration, so as to shorten the operating time of refrigerator refrigeration system, reduces ice to a certain extent The power consumption of case plays certain energy-saving effect.

When the second drawer-bottom board needs to place playback, user pushes handle to square type shell side to movement, hand channel the One shaft drives square type shell to be moved to the direction of the first drawer shell, and the structure installed on bottom mounting plate and bottom mounting plate follows square Shell moves, and side shield and the second drawer-bottom board follow square type shell to move.Have the one end on top to the in the second drawer-bottom board During one drawer riser moves, the top inclined-plane extruding slide damper on the second drawer-bottom board top is oblique by top by top Face, slide damper move upwards, and the second guide block follows slide damper to move, and the second guide block spring is stretched, the second fixed plate phase It is moved downward in the fixed plate sliding groove of slide damper over the ground.When the second drawer-bottom board has one end and first drawer on top When riser is in contact, when the second guide block is located at the top of the second guide groove, top inclined-plane and the sliding of the second drawer-bottom board top end Baffle is bonded by top end by top inclined-plane, and the top cambered surface of the second drawer-bottom board top end is again with slide damper by top Place is constituted a complete smooth cambered surface by top cambered surface.During bottom mounting plate is promoted to the first drawer shell, First friction pulley rotates counterclockwise with drawer slot phase friction rolling in refrigerator, the first friction pulley, and the first friction pulley drives second to rub It wipes wheel to rotate clockwise, the second friction pulley drives the first drawer shell to square type shell by the frictional fit with fricting strip, fricting strip Direction movement；Until the first drawer mechanism and the second drawer mechanism constitute the state of a complete freezer drawer again.

During movement to the direction far from slide damper in the second drawer-bottom board, due to the top of the second drawer-bottom board The effect that place upwarps, the refrigerated item that the top upwarped can place bottom on the second drawer-bottom board play certain interception function, The refrigerated item that bottom is placed does not allow to be also easy to produce shaking, is located at the refrigerated item on the middle and senior level above bottom refrigerated item in this way and is not easy It falls.If the refrigerated item for occurring placing on the second drawer-bottom board is fallen into slide damper by top and the second drawer-bottom board top Behind gap between end, the second drawer-bottom board is moved to slide damper direction, and the top inclined-plane on the second drawer-bottom board top passes through With slide damper by the cooperation by top inclined-plane on top so that the top inclined-plane on the second drawer-bottom board top is by top and second The refrigerated item of gap is ejected between drawer-bottom board top.If under special circumstances, there is the second drawer-bottom board top Top inclined-plane can not be by the refrigerated item of gap between top and the second drawer-bottom board top to be ejected the case where, this when Time just needs artificial mode to take out the refrigerated item of gap.

When the complete freezer drawer that the first drawer mechanism and the second drawer mechanism form needs whole take out, first, make When user needs to rotate handle to bottom mounting plate at plumbness, hand channel first rotating shaft, first gear, second gear and Third gear drives the rotation of the second shaft, the second shaft that elliptic wheel is driven to rotate to the line at two oval ends of elliptic wheel and bottom Mounting plate is at parallel state；When the line at two of elliptic wheel oval ends be gradually varied at plumbness with bottom mounting plate it is ellipse During the line at two oval ends of circle wheel and bottom mounting plate are at parallel state, elliptic wheel makes positive stop strip to separate ellipse The direction movement of circle wheel, the first guide block follow positive stop strip to move, and the first guide block spring is compressed, and positive stop strip has one end of fillet It is inserted into two adjacent banking stops；So positive stop strip can not rotate the rotary stopper of ring set, the second friction pulley, Jin Er One friction pulley can not drive the second friction wheel from rotation, the first friction pulley also can not itself rotation.Then, user's pull handle to Direction movement far from square type shell, drives square type shell to be moved to the direction far from the first drawer shell hand channel first rotating shaft, bottom peace The structure installed in loading board and bottom mounting plate follows square type shell to move, and side shield and the second drawer-bottom board follow square type shell to transport It is dynamic.When freezer drawer needs whole take out, since the first friction pulley can not rotate, so the first friction pulley and drawer in refrigerator The kerve face of slot, which mutually rubs, no longer generates rolling, but becomes sliding between the kerve face of drawer slot in the first friction pulley and refrigerator Friction；Since the second friction pulley can not rotate, so become static friction between the second friction pulley and fricting strip, such second friction Wheel, fricting strip and the first drawer shell are opposing stationary；Square type shell through bottom mounting plate, supporting block, third shaft drive the second friction pulley, Fricting strip and the first drawer shell shell follow square type shell to move, and the first drawer shell and second is taken out between freezer drawer inside complete in this way Relative motion is not will produce between drawer bottom plate.Final complete freezer drawer can be integrally drawn out.

After complete freezer drawer integrally pulls out placement steadily, user rotates handle as the parallel shape of bottom mounting plate State, the line at two of elliptic wheel oval ends is with bottom mounting plate at the company at two ellipse ends that parallel state change is elliptic wheel Line is with bottom mounting plate at plumbness；Under the reset response of the first guide block spring, the first guide block drives positive stop strip to elliptic wheel Direction movement, positive stop strip have fillet one end be detached from from two adjacent banking stops, positive stop strip is no longer to the rotation of ring set Turn limit.

Relative to traditional refrigerator drawer technology, the first drawer mechanism and the second drawer mechanism in the present invention pass through mutual Cooperation can be formed with a complete freezer drawer, have the function of placing article in traditional freezer drawer.By executing machine The action of structure, the first drawer mechanism and the effect of the second drawer organizational separation, which had both may be implemented, in complete freezer drawer to realize The effect that entirety is pulled out out.When complete freezer drawer needs pull out to take refrigerated item, it is only necessary to by the second drawer Bottom plate pulls out just, and all cold airs in such freezer drawer will not be entirely due to the second drawer-bottom board be pulled out and emerged to ice Outside case, after the second drawer-bottom board places original position, maintaining the temperature in freezer drawer as possible will not rise too high；It contracts indirectly The short operating time of refrigerator refrigeration system, reduces the power consumption of refrigerator, plays certain energy-saving effect to a certain extent.This Inventive structure is simple, has preferable using effect.
