[0046] In order to make the technical problems to be solved, technical solutions and beneficial technical effects of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the protection scope of the present invention. And each embodiment may share the same view or multiple views for description, but the features appearing in the same view cannot be interpreted as the features that must be possessed by an embodiment.

[0047] Before starting the description, it should be noted that, for convenience, the present text may use azimuth terms or direction terms for description. These azimuth terms or direction terms are relative to the normal use state of the refrigeration appliance (especially a refrigerator) or the article storage container (especially a drawer) for the refrigeration appliance. Those skilled in the art can clearly understand this from the description of the present utility model without any confusion. In this case, the azimuth terms and direction terms should not be simply interpreted as the azimuth or direction in any state. That is to say, the azimuth or position relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "longitudinal", "transverse", "high", "front", "back", etc. in the description of the present utility model is based on the azimuth or position relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific azimuth, be constructed and operated in a specific azimuth, and therefore should not be construed as a limitation to the present utility model.

[0048] For the convenience of understanding, the description made in the background art part of the present utility model can be recalled or remembered here. One of the purposes of the present utility model is to provide an improved refrigeration appliance, which includes: a storage compartment for accommodating an article storage container; a guide rail assembly disposed on the side wall of the storage compartment for pulling out and pushing in the article storage container from the storage compartment; and a support member disposed on the side of the guide rail assembly away from the side wall. The support member is configured with an upper surface, and a mating portion connected to the article storage container is disposed on the upper surface; wherein, a mating surface opposite to the upper surface is configured on the article storage container, and a first gap is provided between the upper surface and the mating surface along the height direction z of the refrigeration appliance. Thus, the formation of this gap is beneficial to the circulation of the air in the storage compartment through the gap, and is beneficial to reducing the condensation or even icing phenomenon caused by the blockage of the air path between the guide rail assembly, the guide rail assembly and the article storage container.

[0049] The exemplary embodiments of the present utility model will be described below with reference to the drawings.

[0050] Figure 1 A front view of a refrigeration appliance 1000 according to an exemplary embodiment of the present utility model is shown. Figure 2A partial stereoscopic diagram of a refrigeration appliance including an article storage container is shown, wherein the xyz coordinate system of the refrigeration appliance 1000 is schematically shown. As shown in the figure, x represents the width direction of the refrigeration appliance 1000, y represents the depth direction of the refrigeration appliance 1000, and z represents the height direction of the refrigeration appliance 1000. It should be understood here that the xyz coordinate system does not limit the specific direction, that is, it can be either left or right; but the height direction z limits the specific direction against the direction of gravity, and the depth direction y also limits the specific direction from the outside to the inside. For the sake of clarity, the following figures are basically referred to. Figure 1 The xyz coordinate system shown is displayed and described.

[0051] Figure 1 The refrigeration appliance 1000 shown includes a housing 900 and a door body 800 (not shown here), and the door body 800 is used to close the opening 901 of the housing 900. The refrigeration appliance 1000 is preferably configured as a household refrigerator and includes three storage chambers 1001 in the upper, middle and lower parts. Figure 1 The schematically shown lower storage chamber 1001 is described as an example, but it should be understood that the refrigeration appliance 1000 according to an exemplary embodiment of the present utility model may also have only one or another number of storage chambers 1001 .

[0052] Generally, the housing of the refrigeration appliance includes an outer shell, an inner shell, and a heat insulating material located between the inner and outer shells (in the Figure 2 The housing and the insulation material are not shown in the figure), for the storage room 1001, as Figure 2 As shown, the refrigeration appliance 1000 includes two side walls 101 that bound the storage chamber 1001 in the width direction x. An article storage container 200 is arranged in the storage chamber 1001, and the article storage container 200 can be pushed into and pulled out of the storage chamber 1001 through the guide rail assembly 300 arranged on the two side walls 101 of the storage chamber 1001.

[0053] Figure 3 A perspective view showing an integrated assembly of an article storage container and a guide rail assembly according to an exemplary embodiment of the present utility model is shown; Figure 4 A partial stereoscopic view showing a guide rail assembly and a support member provided on a refrigeration appliance according to an exemplary embodiment of the present utility model is shown; Figure 5 An exploded perspective view of an article storage container and a guide rail assembly according to an exemplary embodiment of the present utility model is shown; Figure 6 A side view showing an integrated assembly of an article storage container and a guide rail assembly according to an exemplary embodiment of the present utility model is shown; Figure 7 The figure shows the flow path of wind in a refrigeration appliance according to an embodiment of the present utility model; Figure 8 Shown along Figure 6Sectional view; Figure 9 A perspective view showing the assembly of one side guide rail assembly and the support member according to an exemplary embodiment of the present invention; Figure 10 A perspective view showing the assembly of the other side guide rail assembly and the support member according to an exemplary embodiment of the present invention; Figure 11 A perspective view showing an article storage container according to an exemplary embodiment of the present invention.

[0054] As Figures 3 - 5 shown, the refrigeration appliance 1000 further includes a support member 400, and the support member 400 is disposed on a side of the guide rail assembly 300 away from the side wall 101, so as to provide support for the article storage container 200.

[0055] The support member 400 is configured with an upper surface 401, and a mating portion 500 connected to the article storage container 200 is disposed on the upper surface 401. The mating portion 500 is used to cooperate with the mating structure 205 on the article storage container 200 to form stable support for the article storage container 200.

[0056] The article storage container 200 includes a peripheral wall forming a storage space with an upward opening. Among them, mating structures 205 are disposed on two outer side walls 202 for cooperation with the support member 400.

[0057] As Figure 3 shown, in one embodiment, the mating structure 205 of the article storage container 200 includes a mating surface 201 disposed opposite to the upper surface 401 of the support member 400. Along the height direction z of the refrigeration appliance, a first gap 600 is provided between the upper surface 401 of the support member 400 and the mating surface 201. Thus, the formation of this gap 600 is beneficial to the circulation of the air in the storage chamber 1001 through this gap 600, and is beneficial to reducing the condensation or even icing phenomenon caused by the blockage of the air path between the guide rail assembly, the guide rail assembly 300 and the article storage container 200.

[0058] As Figure 4 shown, in a preferred embodiment, a recessed portion 402 is formed on the upper surface 401 of the support member 400. The recessed portion 402 causes a first gap 600 to be formed between the upper surface 401 and the mating surface 201. In this way, the first gap 600 is large enough so that when the air in the refrigeration appliance passes through the first gap 600, it can have a certain air volume and air speed, which is beneficial to taking away the water vapor accumulated near the guide rail assembly 300 to reduce the possibility of condensation or icing.

[0059] Among them, advantageously, the mating surface 201 can be supported above the upper surface 401 substantially parallel to the upper surface 401. In this way, the size of the first gap 600 is uniform, which is beneficial to the relatively small air resistance for the air to pass through.

[0060] In the present utility model, the guide rail assembly 300 may be a metal guide rail, which includes a fixed rail and a sliding rail, and the support member 400 is disposed on the sliding rail. The guide rail assembly 300 is preferably a C-shaped rail that can withstand heavy loads. The support member 400 is preferably configured as a metal part riveted to the side surface of the sliding rail to provide sufficient supporting force to support the article storage container 200 with a large capacity and capable of carrying a lot of articles.

[0061] In one embodiment, as Figure 5 and Figure 6 shown, a plurality of fitting members are provided between the upper surface 401 and the mating surface 201, such as a first fitting member 510 and a second fitting member 520, to limit the article storage container 200 to the support member 400. Among them, the fitting member may include support portions 511, 521 supported on the upper surface 401 of the support member 400 and a protruding portion. Among them, the first gap 600 is larger than the wall thickness a of the support portions 511, 521. In this way, the first gap 600 is at least larger than the thickness of the fitting members 510, 520 so that when the air in the refrigerating appliance passes through the first gap 600, it can have a certain wind speed and air volume, which is beneficial to taking away the water vapor accumulated near the guide rail assembly to reduce the possibility of condensation or icing.

[0062] Figure 7 Schematically shows the air flow path between the article storage container in the storage chamber and the guide rail assembly. It can be seen that the first gap 600 provides the air flow path of the air in the refrigerating appliance 1000. Preferably, the wind speed of the air flowing through the first gap is not less than 0.1 m / s. Adjusting the gap size can adjust the wind speed passing through the gap. When the wind speed is not less than 0.1 m / s, it is beneficial for the wind to quickly take away the water vapor and reduce the possibility of condensation or icing.

[0063] As Figure 5 shown, the fitting structure 205 of the article storage container 200 is formed at the lower part of the outer side wall 202. Preferably, a step 220 facing the storage space is formed in the middle of the outer side wall 202, and the fitting structure 205 is formed below the step 220. In this way, it is beneficial to maximize the volume of the article storage container 200 and also beneficial to the invisibility of the fitting structure at the front side of the refrigerating appliance 1000.

[0064] The fitting structure 205 may extend along the depth direction z of the article storage container. In a specific embodiment, the fitting structure 205 is formed with a guide rail rib 210 protruding from the corresponding outer side wall 202, and the lower surface of the guide rail rib 210 forms a mating surface 201 facing the upper surface 401 of the support member 400.

[0065] Specifically, as Figures 9 - 10As shown, the first fitting 510 is fixed to the front part of the support 400. The first fitting 510 includes a first support portion 511 and a protruding engaging portion 512. The engaging portion 512 protrudes vertically upward from the upper surface of the support portion 511. A locking hole 211 is formed on the mating surface 201. By mating the engaging portion 512 of the first fitting 510 fixed to the upper surface 401 with the locking hole 211, the article storage container 200 is installed on the support 400 with its movement restricted, which is beneficial to reducing the noise generated during the use of the article storage container 200 and improving the user experience.

[0066] Further, the engaging portion 512 includes elastic arms 512a and fixed arms 512b distributed front and rear along the length direction of the first fitting 510. The elastic arms 512a and the fixed arms 512b are respectively in contact with the locking hole 211, which can restrict the movement of the article storage container 200 relative to the guide rail assembly 300 in the height direction and the depth direction of the storage room 1001. Thus, when being pulled out or pushed into the storage room 1001, it is not easy to shake, which is beneficial to improving the stability and reliability of the connection between the article storage container 200 and the storage room 1001.

[0067] Specifically, the second fitting 520 is fixed to the rear part of the support 400. The second fitting 520 includes a second support portion 521 and a protruding slot portion 522. The slot portion 522 extends from the upper surface of the second support portion 521. By restricting a part of the guide rail rib 210 of the article storage container 200 within the slot portion 522, it is beneficial to reducing the noise generated during the use of the article storage container 200 and improving the user experience.

[0068] Further, the slot portion 522 has a first side wall 522a facing the side wall 101 of the storage room 1001. The first side wall 522a extends backward from the front end of the second support portion 521. In this way, the first side wall 522a of the slot portion 522 can be used to define the movement of the article storage container 200 relative to the guide rail assembly in the width direction of the storage room 1001. In addition, the first side wall 522a of the slot portion 522 also has a guiding function, which can guide the protruding rib 212 at the rear end of the guide rail rib 210 into the slot portion 522, improving the convenience of installation.

[0069] In addition, the slot portion 522 further includes an upper wall 522b that is substantially V-shaped with the second support portion 521. The opening angle of the slot portion 522 is less than 90°. Correspondingly, the shape of the protruding rib 212 is V-shaped, and the inclination angle of the protruding rib is less than the opening angle of the slot portion. In this way, under the guiding action of the inclined upper wall 522b of the slot portion 522, the protruding rib 212 is easily inserted into the slot portion 522.

[0070] In this specific implementation, in order to improve the strength of the guide rail rib 210 and the second fitting 520 to ensure the reliability of the connection, several first reinforcing ribs 213 may also be provided on the guide rail rib 210; or multiple second reinforcing ribs 526 may also be provided on the rear side of the slot portion 522.

[0071] In some specific embodiments, the first fitting 510 is snap-fitted onto the support member 400 from top to bottom to provide forward and lateral displacement limitations of the first fitting 510 to the article storage container 200. The second fitting 520 is snap-fitted onto the support member 400 from front to back to provide backward and lateral displacement limitations of the second fitting 510 to the article storage container 200. Thus, when being pulled out or pushed into the storage room 1001, it is not likely to shake, which is beneficial to improving the stability and reliability of the connection between the article storage container 200 and the storage room 1001.

[0072] As Figure 6 shown, the first gap 600 may be provided in the middle of the relatively arranged area of the upper surface 401 and the mating surface 201, and its length is not less than half of the length of the support member 400. In this way, it is beneficial to maximize the extension length of the gap in the depth direction z of the storage room as much as possible, and it is beneficial to provide flowing air along the length direction of the guide rail assembly as much as possible to take away the accumulated water vapor, which is beneficial to preventing condensation or icing.

[0073] In particular, specifically, the recessed portion 402 may be provided on the first fitting 510 and the second fitting 520, which is beneficial to continuously form the gap to provide a relatively low-resistance air flow path.

[0074] From Figure 7 it can be seen that in order to facilitate the air to flow out of the article storage container 200 to provide sufficient air volume flowing towards the guide rail assembly 300, it is preferably provided with an air outlet 203 on the outer side wall 202 of the article storage container 200 that is at least higher than the mating surface 201. In this way, it is beneficial that at least part of the air in the article storage container 200 flows through the air outlet 203 and the first gap 600 under the attraction of the fan and returns to the air return opening 103 in the storage room 1001. In particular, the air outlet can be configured in a grid shape. In order to ensure the air volume, along the depth direction y of the refrigeration appliance, the extended length of the grid-shaped air outlet 203 is not less than one-third of the depth of the article storage container 200.

[0075] In some specific embodiments, along the height direction z of the refrigeration appliance, an air supply opening not lower than the rear wall of the article storage container 200 is provided on the inner wall of the storage room 1001. That is to say, when there are stacked article storage containers 200 in the storage room, an air supply opening 102 may be provided behind the rear wall of the uppermost article storage container 200, or an air supply opening 102 may be provided above the rear wall of each article storage container 200.

[0076] Preferably, the air return opening 103 is disposed below the storage chamber 1001.

[0077] As Figure 8 shown, in the width direction x of the refrigerating appliance, a second gap 700 is formed between the outer surface of the support member 400 away from the side wall 101 and the outer side wall 202 of the opposing article storage container 200. Thus, the air flowing out of the article storage container 200 at least partially flows through the air outlet 203, the first gap 600, and the second gap 700 to return to the air return opening 103 in the storage chamber 1001.

[0078] The second gap 700 provides a flow path for the air within the refrigerating appliance, providing flowing air to carry away the water vapor accumulated between the article storage container and the support member, which is conducive to preventing condensation or icing.

[0079] Preferably, the wind speed of the air flowing through the second gap is not less than 0.1 m / s. Thus, the air with a certain wind speed and air volume can carry away the water vapor between the article storage container 200 and the support member 400 to reduce the possibility of condensation and icing.

[0080] Figure 11 shows an exploded perspective view of the storage container and the guide rail assembly in another exemplary embodiment of the present utility model. Figure 12 shows Figure 11 the air flow path within the refrigerating appliance in another embodiment.

[0081] As Figures 11 - 12 shown, a mating surface 201 is formed on the article storage container 200 opposite to the upper surface 401 of the support member 400. A plurality of vertically downwardly protruding bosses 206 are provided on the mating surface 201, and a plurality of groove portions 406 mating with the bosses are provided on the upper surface 401. Along the height direction z of the refrigerating appliance, some of the bosses 206 fall into the groove portions 406 and are thus limited within the groove portions 406 to form the first gap 600 between the upper surface 401 and the mating surface 201.

[0082] In a preferred embodiment, the groove portion 406 is preferably a groove, and its bottom surface is in the same plane to ensure that the article storage container 200 can be stably supported and the size of the first gap 600 is almost uniform.

[0083] In order to stably hold the article storage container 200 on the support member 400, mating structures 205 are respectively provided on the mating surface 201 and its rear wall 204, such as a first limiting protrusion 208 provided on the mating surface 201 and a second limiting protrusion 207 provided on the rear wall 204, to limit and mate with the mating portion 500 on the support member 400.

[0084] In this embodiment, the first limiting bump 208 cooperates with the limiting hole 408 on the upper surface 401, and the second limiting bump 207 cooperates with the clamp formed by the upper surface 401. The two work together to limit the displacement of the article storage container 200 in the front-back, left-right, up-down directions.

[0085] Of course, in this embodiment, there is a second gap similar to that in the previous embodiment, and the same requirements for the size of the gap are also applicable, so no further elaboration will be made here.

[0086] In some specific embodiments, especially when the guide rail assembly is a heavy-duty guide rail, it has a more obvious effect on the problems of condensation and icing. The connecting rail between the heavy-duty guide rail and the side wall 101 is wider to provide a greater moment, so using a support member can provide a larger support surface. However, in some refrigeration systems, condensation or icing is also likely to occur.

[0087] In some specific embodiments, when the storage compartment 1001 is provided with a pull-out article storage container in the freezer compartment, it also has a relatively more significant effect on the problems of condensation and icing of the guide rail assembly.

[0088] In the present utility model, the support member 400 is preferably constructed as a sheet metal part, including a bent portion forming the upper surface 401 and a main body portion forming the outer surface 403 and fixedly connected to the guide rail assembly 300 to provide sufficient support force for the heavy-duty container.

[0089] Preferably, the support member 400 extends along the length direction of the guide rail assembly 300 to provide a continuous upper surface 401. In particular, the length of the support member 400 is substantially the same as the length of the guide rail assembly 300, which is beneficial to the strength of the support member to provide stable support for the heavy-duty container.

[0090] In order to form a recess 402 on the upper surface 401 of the support member 400 to provide a sufficiently large first gap 600, a cut 404 is provided in the region where the upper surface 401 and the outer surface 403 of the support member 400 intersect to facilitate the formation of the recess 402, and the cut 404 also additionally provides a flow path for air.

[0091] Furthermore, a bent portion 405 is provided below the mating portion 500 on the support member 400 and bent in the direction of the article storage container 200. The bent portion 405 is beneficial to providing a space between the support member and the guide rail assembly to accommodate the connecting portion of the mating member passing through the support member 400. Of course, the bent portion 405 is also beneficial to enhancing the strength of the support member 400.

[0092] It can be understood that in the present application, the guide rail assemblies 300 are provided in a pair on the opposed side walls 101. Therefore, a support member 400 is provided on each guide rail assembly 300, and there is a first gap 600 between the upper surface 401 of each support member 400 and the mating surface 201 of the article storage container 200. Although the foregoing does not separately describe the left and right sides, it can be understood that in order to maintain the balance and stability of the support forces on both sides of the article storage container 200, the guide rail assemblies, support members, and connection structures on both sides are generally designed in pairs and symmetrically. The above description is not limited to a certain side.

[0093] Although the specific embodiments have been described above, these embodiments are not intended to limit the scope of the disclosure of the present utility model, even in the case where only a single embodiment is described with respect to a specific feature. The feature examples provided in the disclosure of the present utility model are intended for illustrative purposes only and not for limitation, unless otherwise expressly stated. In specific implementations, multiple features may be combined with each other according to actual needs and where technically feasible. Various substitutions, changes, and modifications can also be conceived without departing from the spirit and scope of the present utility model.
