A refrigerator is a device for keeping food stored in a storage compartment fresh at a low temperature by supplying low-temperature air to the storage compartment. The existing refrigerator includes a freezing chamber and a refrigerating chamber, and the temperature of the freezing chamber is lower than that of the refrigerating chamber.

In recent years, refrigerators with an ice making function have been more and more popular with consumers. An ice-making unit, which is generally provided in a freezer compartment of a refrigerator, includes an ice-making tray to receive water to make ice cubes; the ice storage box is arranged below the ice making tray and used for containing ice blocks; and the ice maker main body is fixed in the inner container of the freezing chamber.

In the above-described ice-making unit, the ice bank is configured to be pushed in or pulled out of the freezing chamber, and the pushing in and pulling out of the ice bank is performed in synchronization with the pushing in and pulling out of the drawer of the freezing chamber. The disadvantage of this type of design is that when the user only accesses frozen food without the need for ice, the ice bank is pulled out simultaneously each time the freezer drawer is pulled open, and the food in the freezer drawer easily contaminates the ice in the ice bank. In addition, the ice bank is pulled out to accelerate the melting of ice cubes to cause ice adhesion, so that the quality of ice for a user is degraded.

In addition, most of the existing ice banks are of an open structure, and when the ice making unit makes ice in the freezing chamber, the ice banks of the open structure and the storage objects of the freezing chamber are easily interfered with each other, so that ice blocks are polluted.

As shown in fig. 2 and 3, when the drawer 100 is pulled out to the first position, the ice bank 22 remains closed and is not opened. That is, in the first stroke stage of the drawer 100, the drawer 100 is pulled open, the ice bank 22 is closed on the support 21, and the user can take and put the stored objects in the drawer 100. Since the ice bank 22 is closed on the support 21, the taking and placing operations of the stored objects do not affect the ice cubes in the ice bank 22.

As shown in fig. 2 and 7, when the drawer 100 is pulled out to the second position (or, pulled out beyond the first position), the ice bank 22 is pulled out from the cradle 21 as the drawer 100 moves. That is, during the second stroke of the drawer 100, the drawer 100 is continuously pulled, and the ice bank 22 is pulled out of the support 21 along with the movement of the drawer 100, at which time, the user can access the ice cubes in the ice bank. After ice fetching is completed and the ice bank 22 needs to be closed, the ice bank 22 can be manually pushed into the bracket 21, the drawer 100 can also be pushed into the liner of the refrigerator, when the drawer 100 is pushed to the first position, the front side wall 112 of the drawer 100 pushes against the front side wall 222 of the ice bank 22, the drawer 100 is continuously pushed, and the drawer drives the ice bank 22 to be pushed into the bracket 21. Wherein, the mode that ice storage box 22 was driven and was opened by drawer 100 has saved the user and after pulling open drawer 100, still need open the operation of ice storage box 22 alone, has strengthened the convenience of getting ice, promotes user experience.

In this embodiment, the second position is closer to the user than the first position.

In order to realize asynchronous pulling of the drawer 100 and the ice storage box 22, a first stop 1110 is arranged on the drawer bottom 111 of the drawer 100, a second stop 50 is arranged at the bottom of the ice storage box 22, and when the drawer 100 is pulled out to be at a first position, the front side 1111 of the first stop 1110 abuts against the second stop 50; the drawer 100 is continuously pulled out beyond the first position toward the second position, and the front side 1111 of the first stopper 1110 pushes against the second stopper 50, so that the ice bank 22 is pulled out from the cradle 21.

As shown in fig. 5, 6, 10 and 11, the first stopper 1110 is, for example, a projection protruding upward from the drawer bottom 111. The first stop 1110 has an uppermost position 1113 between the front side 1111 and the rear side 1112. Thus, the front side 1111 includes a first slope that gradually slopes upward toward the uppermost position 1113, and the back side 1112 includes a second slope that gradually slopes downward toward the uppermost position 1113. That is, the first slope and the second slope incline in opposite directions. When the drawer 100 is pulled to the first position and the second position, the second stopper 50 abuts against the first slope of the front side 1111 of the first stopper 1110.

In order to ensure that the user can smoothly access the stored articles in the right compartment of the drawer 100 when in the first position, a first stopper 1110 is provided along the longitudinal side (short side) of the bottom plate 111 at a position 1/2-2/3. Wherein, when the first stopper 1110 is located at the length 1/2 of the longitudinal side edge, the distance from the first stopper 1110 to the front side wall and the rear side wall of the drawer 100 is substantially equal; when the first stopper 1110 is located at the length of 2/3 from the longitudinal side, the distance from the first stopper 1110 to the front side wall of the drawer 100 is 2/3 of the length of the longitudinal side, and the distance from the first stopper 1110 to the rear side wall of the drawer 100 is 1/3 of the length of the longitudinal side. In summary, the first stopper 1110 may be disposed in a rear half area of the longitudinal side (short side) of the bottom plate 111 near the rear wall of the inner container of the refrigerator, so that it is ensured that the drawer 100 is pulled out as far as possible without the ice bank 22 to provide a sufficient taking space.

The second stopper 50 is disposed at the bottom of the ice bank 22, and a lower portion of the second stopper 50 protrudes from an ice bank floor 223 of the ice bank 22. Preferably, the lower portion of the second stopper 50 also protrudes from the bracket bottom plate 213 of the bracket 21. The bank floor 213 is located below the ice bank floor 223. In addition, the second stopper 50 is located at the front end of the ice bank floor 223.

An extending portion 224 extends from the front sidewall 222 of the ice bank 22, a space between the extending portion 224 and the front sidewall 222 of the ice bank 22 forms a engaging slot 225, and an upper portion of the second stopper 50 is engaged in the engaging slot 225. The extension 224 is substantially T-shaped or L-shaped. The extension 224 is located inside the front sidewall 222 of the ice bank 22, but not limited thereto.

The bottom of the engaging groove 225 has an open end through which the lower portion of the second stopper 50 protrudes from the ice bank bottom 223. In addition, the second stopper 50 further includes a hook 53, the hook 53 is adapted to the engaging hole in the engaging groove 225, and the hook 53 is engaged in the engaging hole, so that the second stopper 50 is engaged in the engaging groove 225.

As shown in fig. 6 and 11, the first elastic member 60 is disposed between the upper portion 52 of the second stopper 50 and the extending portion 224, opposite ends of the first elastic member 60 elastically abut against the extending portion 224 and the upper portion 52 of the second stopper 50, respectively, and the lower portion of the second stopper 50 is always in contact with the drawer bottom 111. In other words, the first elastic member 60 provides an elastic force to elastically press the lower portion of the second stopper 50 against the drawer bottom 111. The second stopper 50 is elastically pressed against the drawer bottom 111, so that the device damage caused by the hard interference between the drawer bottom 111 and the ice bank bottom 223 during the process of pulling out or pushing in the drawer 100 can be effectively prevented, and the tolerance capability of the error caused by the manufacture and assembly of the drawer 100 and the ice-making unit 20 can be increased.

In the present embodiment, the first elastic member 60 is, for example, a spring. In addition, the upper portion 52 and the extending portion 224 of the second stopping member 50 can be respectively provided with a positioning post, and two ends of the first elastic member 60 are respectively sleeved on the positioning posts, so as to facilitate the assembly of the first elastic member 60.

With continued reference to fig. 6 and 11, in order to reduce noise caused by interference between the second stopper 50 and the drawer bottom 111 during the process of pulling and pushing the drawer 100, rollers 51 are further disposed at the bottom of the second stopper 50, and preferably, the rollers 51 are disposed at the left and right sides of the bottom of the second stopper 50. When the drawer 100 is pulled and pushed, the roller 51 rolls against the front side 1111 of the first stopper 1110 of the drawer bottom 111, thereby reducing the abrasion and noise caused by the interference contact between the lower portion of the second stopper 50 and the drawer bottom 111. Preferably, the roller 51 is a silicone rubber roller.

In addition, the second stopper 50 adopts the design of combining the first elastic member 60 and the roller 51, so that the friction between the second stopper 50 and the drawer bottom 111 can be significantly reduced in the process of pulling the drawer 100 to the first position and continuously pulling the drawer 100 to pass through the first position to drive the ice bank 22 to be pulled out of the bracket 21, therefore, the lower part of the second stopper 50 can be always stopped by the front side 1111 of the first stopper 1110, and cannot pass through the highest position 1113 of the first stopper 1110, and the ice bank 22 cannot be driven by the drawer 100 to be pulled out.

As shown in fig. 3, 4, 8 and 9, a pulley and a slide rail are provided between the ice bank 22 and the support 21, to further reduce sliding frictional resistance when the ice bank 22 is pulled out and pushed in the support 21, so that the pulling out and pushing in processes are smoother.

As shown in fig. 3 and 4, the bracket 21 includes a bracket bottom plate 213 and a first vertical wall extending upward from the periphery of the bracket bottom plate 213, the first vertical wall includes a bracket rear side wall 212 and an opposite first side wall 211, a first guide rail is disposed inside the first side wall 211, and the first guide rail includes an upper rail 31 and a lower rail 32, and a slide groove 33 between the upper and lower rails.

The ice bank 22 includes an ice bank floor 223 and a second vertical wall extending upward from a periphery of the ice bank floor 223, the second vertical wall including an ice bank rear, a front side wall 222, and an opposite second side wall 221, an outer side of the second side wall 221 being provided with the first pulley 41, and the first pulley 41 being located at a rear end of the second side wall 221 corresponding to a rear end of the first rail.

As shown in fig. 6 and 11, the ice bank 22 is closed on the support 21, and the first pulley 41 is received in the rear end of the chute 33; the ice bank 22 is pulled out of the cradle 21 and the first pulley 41 slides along the chute 33 to the front end. In order to prevent the ice bank 22 from falling out of the bracket 21 due to an external force when the ice bank 22 is closed on the bracket 21, a slope 321 is provided at a rear section of the lower rail 32, and the slope 321 is inclined downward toward a rear end of the lower rail 32.

In addition, when the ice bank 22 is pushed into the support 21, the slope 321 guides the first pulley 41 to move toward the rear end of the chute 33, and the gravity self-locking after the ice bank 22 is pushed in is realized by using the self weight of the ice bank 22, thereby improving the user experience.

Further, a second pulley 34 is arranged at the front end of the lower guide rail 32, and the second pulley 34 is pivoted on the inner side of the first side wall 211; a second guide rail 42 is provided outside the second sidewall 221 of the ice bank 22 corresponding to the second pulley 34; the second guide rail 42 is located in the slide groove 32, and the first pulley 41 is located at the rear end of the second guide rail 42.

During the sliding of the first pulley 41 in the chute 33 on the second sidewall 221 of the ice bank 22, the second pulley 34 simultaneously slides along the second rail 42 to better lift the smoothness of the sliding of the ice bank 22 pulled out or pushed into the cradle 21.

As shown in fig. 9, a slope 421 extending obliquely upward is disposed at the front end of the second rail 42, the ice bank 22 is pushed into and closed on the support 21, the slope 421 is used to maintain the level of the ice bank 22, and the second roller 34 will not lift the front end of the second rail 42 because the first pulley 41 falls onto the slope 321 at the rear end of the lower rail 32.

In this embodiment, the pair of first sidewalls 211 corresponds to the pair of second sidewalls 221 one by one, and the inner side of the first sidewalls 211 is adjacent to the outer side of the second sidewalls 221. The upper rail 31 and the lower rail 32 extend from the inner side of the first sidewall 211 toward the outer side of the second sidewall 221; the second guide rail 42 extends from the outside of the second side wall 221 toward the inside of the first side wall 211, and is located in the slide groove 33 between the upper rail 31 and the lower rail 32.

In other embodiments of the present invention, the second roller may also be disposed at the front end of the upper rail or at other positions.

As can be seen from the above description, in the drawer 100 of the refrigerator according to the first embodiment of the present invention, the ice-making unit 20 is accommodated in at least one of the compartments of the drawer 100, the bracket 21 of the ice-making unit 20 provides a relatively sealed space, and the ice storage box 22 is accommodated in the relatively sealed space, so that contamination of ice cubes in the ice storage box 22 by other compartments of the drawer 100 is avoided. In addition, the drawer 100 is pulled or pushed into the refrigerator within a certain range of travel without being synchronized with the pulling or pushing of the ice bank 22 into the bracket 21, so that the problem of ice block adhesion in the ice bank due to the fact that the existing drawer and the ice bank are pulled or pushed synchronously while the user can freely store and take the stored objects in the drawer is solved.

Specifically, when the drawer 100 of the refrigerator according to the first embodiment of the present invention is pulled to the first position (the position shown in fig. 2), the first stopper 1110 protruding from the drawer bottom 111 and the second stopper 50 protruding from the bottom of the ice bank 22 abut against each other; the drawer 100 is further pulled out to pass through the first position to the second position (the position shown in fig. 7), the second position is the maximum opening position, the first stopper 1110 pushes against the second stopper 50, the drawer 100 drives the first pulley 41 on the ice bank 22 to slide along the chute 33 in the support 21, and the ice bank 22 is pulled out.

When closing the ice bank 22, a user may manually push the ice bank 22 against the front sidewall 222 of the ice bank 22 to individually push the ice bank 22 into the cradle 21; alternatively, the user may push the ice bank 22 into the cradle 21 by pushing the drawer 100 into the refrigerator, and the drawer side wall 112 of the front side of the drawer 100.
