The upper, lower, left, right, front and rear directions illustrated in some of the drawings provided in the embodiments of the present invention are only for convenience of describing the technical solutions of the embodiments of the present invention, and do not constitute a limiting explanation of the solutions.

In order to make the objects, features and advantages of the embodiments of the present invention more comprehensible, specific embodiments accompanied with figures are described in detail below.

The embodiment of the invention provides a refrigerating device.

In particular, the refrigeration appliance may be an appliance suitable for storing articles at a relatively low temperature and refreshing the stored articles, such as a refrigerator, a freezer, or the like.

Referring to fig. 1, a refrigerating apparatus 1 includes a storage compartment 20 and a drawer assembly 10 received within the storage compartment 20. The storage compartment 20 has first and second sidewalls 21 and 22 disposed opposite to each other, and the drawer assembly 10 is installed between the first and second sidewalls 21 and 22.

Referring to fig. 2 to 6, the drawer assembly 10 includes a drawer 100, a pair of rails 200 installed with respect to the outer sidewalls 110 of the drawer 100, and guide posts 300 movably coupled to the pair of rails 200, respectively. Wherein the drawer 100 can be moved outwardly with respect to the storage compartment 20 (or forwardly with respect to the storage compartment 20) to be drawn out and moved inwardly (or rearwardly with respect to the storage compartment 20) to be pushed in by the guide rails 200 and the guide posts 300.

Specifically, one of the guide rail 200 and the guide post 300 is mounted to the outer sidewall 110 of the drawer 100, and the other is mounted to the first and second sidewalls 21 and 22 of the storage compartment 20. The guide posts 300 are adapted to move along the rails 200 such that the drawer 100 is adapted to move outwardly to at least partially pull out of the storage compartment 20 and inwardly to at least partially push into the storage compartment 20.

In the example shown in fig. 2 to 6, the guide rail 200 is fixed to the first and second sidewalls 21 and 22 of the storage compartment 20, and the guide post 300 is rotatably installed to the outer sidewall 110 of the drawer 100.

In a specific implementation, a rolling bearing may be used to rotatably mount the guide post 300 to the outer sidewall 110 of the drawer 100, and such that the guide post 300 is rotatable relative to the outer sidewall 110 about a central axis i of the rolling bearing.

Specifically, the guide post 300 includes a first guide post 310 and a second guide post 320. The first guide post 310 and the second guide post 320 are rotatably mounted to the outer sidewalls 110 of the drawer 100, respectively.

The guide rail 200 includes first and second mounting grooves 210 and 220, and a guide groove 240 communicating with the first and second mounting grooves 210 and 220, respectively. The first mounting groove 210 is disposed corresponding to the first guide pole 310 and adapted to guide the first guide pole 310 to the guide groove 240, and the second mounting groove 220 is disposed corresponding to the second guide pole 320 and adapted to guide the second guide pole 320 to the guide groove 240.

The first guide post 310 and the second guide post 320 are adapted to move along the guide groove 240 to pull or push the drawer 100 between the first moving position and the second moving position.

In some possible specific examples, the drawer 100 is pushed completely into the storage compartment 20 when in the first moving position and is pulled out of the storage compartment 20 to the maximum extent when the drawer 100 is in the second moving position. Wherein the maximally pulled out of the storage compartment 20 represents the limit at which the drawer 100 can be pulled out with respect to the storage compartment 20.

The guide rail 200 further includes a stopper 250 positioned in the guide groove 240. The stopper 250 is adapted to stop the first guide post 310 to prevent the first guide post 310 from sliding out of the rail 200 when the drawer 100 is in the first moving position (i.e., when the drawer 100 is pushed into the storage compartment 20) and to stop the second guide post 320 to prevent the second guide post 320 from sliding out of the rail 200 when the drawer 100 is in the second moving position (i.e., when the drawer 100 is pulled out of the storage compartment 20).

By adopting the technical scheme provided by the embodiment of the invention, the drawer 100 can move outwards relative to the storage chamber 20 under the action of the guide rails 200 and the guide posts 300 to be pulled out and pushed in, and the drawer 100 can be limited by the limiting part 250 when being pulled out or pushed in, so that the stability of the drawer 100 when being pulled out or pushed in is ensured.

Further, the guide post 300 further includes a third guide post 330. The guide rail 200 further includes a third mounting groove 230 adapted to guide the third guide post 330 to the guide groove 240. The third guiding post 330, the second guiding post 320 and the first guiding post 310 are sequentially arranged along the drawing direction of the drawer 100.

The third guide post 330 is adapted to move along the guide groove 240 and to be stopped by the guide groove 240 when the drawer 100 moves to the second movement position (i.e., when the drawer 100 is pulled outward), so as to prevent the drawer 100 from being turned over when being pulled outward.

Specifically, the guide groove 240 has a moving surface 241 adapted to the movement of the first guide post 310, the second guide post 320, and the third guide post 330. Motion surface 241 includes a first location 242, a second location 243, and a third location 244.

When the drawer 100 is in the first moving position, the first guide post 310, the second guide post 320, and the third guide post 330 are in the first position 242, the second position 243, and the third position 244, respectively. When the drawer 100 moves from the first moving position to the second moving position, the first guiding post 310 moves from the first position 242 to the direction of pulling out the drawer 100 beyond the limiting portion 250, the second guiding post 320 moves from the second position 243 to the first position 242, and the third guiding post 330 moves from the third position 244 to the second position 243.

In some possible specific examples, the moving surface 241 of the guide groove 240 is a convex arc surface. The convex arc surface is adapted to allow the drawer 100 to be inclined downward when being pulled out. Therefore, the article can be conveniently taken and placed, and the drawer 100 can be inclined downwards just when being pulled out, so that the drawer 100 is prevented from being inclined downwards to generate a sharp feeling when being pulled out quickly.

Further, the moving surface 241 includes a first moving section 245 between one end thereof to the first position 242, a second moving section 246 between the first position 242 to the second position 243, and a third moving section 247 between the second position 243 to the other end thereof. Wherein the first moving section 245 is adapted for the first guiding stud 310 to move, the second moving section 246 is adapted for the second guiding stud 320 to move, and the third moving section 247 is adapted for the third guiding stud 330 to move.

In a specific implementation, the height h of the guide slot 240 at the second motion segment 246 is set to be less than the diameter d of the third guide post 330. In this manner, the third guide post 330 is restricted from moving from the second position 243 toward the second motion section 246 as the drawer 100 is pulled out to the second motion position, thereby preventing the drawer 100 from continuing to pull out from the second motion position.

Referring to fig. 7 to 9, the stopper portion 250 includes a convex portion 251 extending upward along the moving surface 241. The projection 251 is adapted to limit movement of the first guide post 310 from the first position 242 toward the first motion section 245 when the drawer 100 is in the first motion position and is overcome by the first guide post 310 when a force to pull or push the drawer 100 is greater than a threshold.

In the embodiment of the present invention, since the protrusion 251 extends upward relative to the moving surface 241 of the guide groove 240, a certain resistance needs to be overcome when the first guide pole 310 passes through the protrusion 251.

When no force is applied to the drawer 100, the first guide post 310 is stopped by the protrusion 251 because it cannot overcome the resistance required to pass the protrusion 251, thereby preventing the drawer 100 from sliding outward with respect to the storage compartment 20.

When the force for pulling out or pushing in the drawer 100 is greater than the threshold value, the first guiding pillar 310 can overcome the required resistance to the force by the pulling or pushing force to pass the protrusion 251, so that the drawer 100 can move outward to pull out or move inward to push in.

In some possible specific examples, the guide groove 240 is open at an end 248 thereof adjacent to the first mounting groove 210. The first guide post 310 is adapted to move beyond the stopper 250 to the outside of the guide rail 200 through the one end 248 of the first mounting groove 210 when the drawer 100 moves from the first movement position to the second movement position (i.e., when pulled outward). In this way, the pulling-out amplitude of the drawer 100 can be increased, so as to facilitate the taking and placing of the articles.

When the first guide post 310 moves out of the guide rail 200 and the drawer 100 moves to the second movement position, the third guide post 330 can be limited by the guide groove 240, so that the drawer 100 cannot turn around the second guide post 320 when being pulled out, thereby ensuring the stability of the drawer 100 when being pulled out.

In other possible specific examples, the maximum width w of the second mounting groove 220 may be set to be smaller than the diameter d of the third guide post 330. In this way, the third guide post 330 is prevented from moving out of the guide rail 200 from the second mounting groove 220 due to the downward inclination of the drawer 100 when moving along the guide groove 240, thereby ensuring the stability of the drawer 100 during the drawing process.

Referring to fig. 7 to 9, the stopper portion 250 further includes a blocking portion 252. The blocking portion 252 is adapted to limit the movement of the second guide post 320 from the first position 242 to the first movement section 245 when the drawer 100 is in the second movement position.

In a particular implementation, the guide slot 240 includes a stop surface 260 disposed opposite the second motion segment 246. The stop surface 260 cooperates with the second motion segment 246 to limit the motion of the second guide post 320 within the guide slot 240.

Referring to fig. 7 and 8, in some specific examples, the depth h1 of the first motion segment 245 is less than the depth h2 of the second motion segment 246 to form a stop 252 that stops the second guide post 320 when the drawer 100 is in the second motion position.

In a particular implementation, the stop 252 may be an end surface formed by the stop surface 260 extending toward the second motion segment 246. The end surface may extend toward the projection 251 (see fig. 7) or be located on a side of the projection 251 remote from the first motion segment 245 (see fig. 8).

Referring to fig. 9, in other specific examples, the first motion segment 245 and the second motion segment 246 have the same depth. The stop 252 may be a stop disposed between the stop face 260 and the second motion segment 246. When the second guiding post 320 is mounted to the drawer 100, the stopping block is located at a position where the protruding portion 251 is far away from the outer sidewall 110 of the drawer 100 to limit the second guiding post 320 when the drawer 100 is located at the second moving position.

In the embodiment of the present invention, the outward movement of the drawer 100 due to being pulled out can be stopped by the stopping portion 252 stopping the second guiding column 320, and the guiding groove 240 stopping the third guiding column 330 at the second position 243. As long as at least one of the second guiding post 320 and the third guiding post 330 is restrained, the drawer 100 stops moving outward and reaches the maximum pulling amount.

Referring to fig. 10, a horizontal distance from the second position 243 to the blocking part 252 may be denoted as a first horizontal distance l1, and a horizontal distance from the third position 244 to the second position 243 may be denoted as a second horizontal distance l 2. The maximum pulled-out amount of the drawer 100 is the smaller one of the first horizontal distance l1 and the second horizontal distance l 2.

Thus, the maximum pulling amount of the drawer 100 can be controlled by adjusting the first horizontal distance l1 and/or the second horizontal distance l2 of the guide groove 240.

In the embodiment of the present invention, when the drawer 100 is completely pulled out and the first guide post 310 moves out of the guide groove 240, the drawer 100 is supported to the guide groove 240 of the rail 200 by means of the second guide post 320 and the third guide post 330. At this time, the angle at which the drawer 100 can be flipped down with respect to its pushed-in state is determined by the relative positions of both the second guide post 320 and the third guide post 330.

Thus, the angle at which the drawer 100 can be flipped down when fully pulled out can be controlled by adjusting the relative position of the second guide post 320 and/or the third guide post 330.

Specifically, the relative positions of the second guide post 320 and the third guide post 330 may be adjusted by adjusting the horizontal distance and the vertical distance thereof. For example, when the horizontal distance of the second guide post 320 and the vertical distance of the third guide post 330 are closer and the vertical distance is farther, θ is larger, and the angle at which the drawer 100 can be flipped down is also larger. For another example, when the horizontal distance of the second guide post 320 and the vertical distance of the third guide post 330 are relatively long and the vertical distance is relatively short, θ is relatively small, and the angle at which the drawer 100 can be flipped down is also relatively small.

In one embodiment, referring to fig. 11, when the drawer 100 is completely pulled out, the angle between the line connecting the second guiding column 320 and the third guiding column 330 and the horizontal direction can be recorded as θ. The smaller θ, the smaller the angle by which the drawer 100 can be flipped down, and the larger θ, the larger the angle by which the drawer 100 can be flipped down.

In an embodiment of the present invention, the first guide post 310, the second guide post 320 and the third guide post 330 may be provided with different diameters, and the width of the mounting slot corresponding to each guide post is adjusted accordingly, so as to ensure the assembly correctness between each guide post and the corresponding mounting slot and provide a supporting point for the downward inclination of the drawer 100.

While specific embodiments have been described above, these embodiments are not intended to limit the scope of the present disclosure, even where only a single embodiment is described with respect to a particular feature. The characteristic examples provided in the present disclosure are intended to be illustrative, not limiting, unless differently stated. In particular implementations, the features of one or more dependent claims may be combined with those of the independent claims as technically feasible according to the actual requirements, and the features from the respective independent claims may be combined in any appropriate manner and not merely by the specific combinations enumerated in the claims.

Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
