Description

TECHNICAL FIELD

[0001] The present application relates to the field of household appliances, in particular to a vertical beam assembly for a refrigerator door body and a refrigerator. BACKGROUND

[0002] Large-capacity refrigerators in the prior art usually adopt a split door body assembly, wherein a vertical beam assembly is usually arranged on the split door body assembly to close the gap between the split door body assembly and the cabinet. Due to the large temperature difference between the inside and outside of the refrigerator, condensation is easily formed on the surface of the vertical beam assembly, thereby affecting the user's experience.

[0003] In order to avoid the surface of the vertical beam assembly from producing condensation, the prior art usually arranges a heating wire on the vertical beam assembly to heat the surface of the vertical beam assembly. However, it is found in actual practice that the temperature of part of the surface of the vertical beam assembly is still lower than the condensation temperature, so that the condensation cannot be eliminated, while the temperature of another part of the surface is already much higher than the condensation temperature, causing an additional heat load to the storage compartment, thereby increasing the energy consumption of the refrigerator. SUMMARY

[0004] An object of the present application is to provide a vertical beam assembly for a refrigerator door body and a refrigerator which at least solve any of the above technical problems.

[0005] A further object of the present application is to improve the surface temperature uniformity of the vertical beam assembly for the refrigerator door body.

[0006] Another further object of the present application is to reduce the energy consumption of the refrigerator.

[0007] In particular, the present application provides a vertical beam assembly for a refrigerator door body, comprising: a vertical beam body; a cover plate, which is buckled on the vertical beam body and defines a heating cavity with the vertical beam body; and a heating wire, which is arranged in the heating cavity and is configured to have a higher arrangement density at the sections of both ends of the vertical beam body than at the section of the middle of the vertical beam body.

[0008] Further, the sections of both ends of the vertical beam body are arranged to extend in a meandering manner along the length direction of the vertical beam body, and the section of the middle of the vertical beam body is arranged to extend in a straight line along the length direction of the vertical beam body.

[0009] Further, the arrangement density of the heating wire at the first end of the vertical beam body is higher than that at the second end of the vertical beam body, wherein the first end of the vertical beam body is arranged to be close to one end of the bottom of the refrigerator door body, and the second end of the vertical beam body is arranged to be close to one end of the top of the refrigerator door body.

[0010] Further, the length of the heating wire windingly extending at the first end of the vertical beam body is greater than the length of the heating wire windingly extending at the second end of the vertical beam body; wherein the first end of the vertical beam body is arranged at one end close to the bottom of the refrigerator door body, and the second end of the vertical beam body is arranged at one end close to the top of the refrigerator door body.

[0011] Further, the vertical beam body comprises a bottom shell, a cover shell, the cover shell being buckled on the bottom shell to define a foaming space for filling the thermal insulation layer with the bottom shell, and the cover shell and the cover plate define a heating cavity.

[0012] Further, one end of the vertical beam body is further provided with a pouring hole for injecting a foaming material forming the thermal insulation layer into the foaming space.

[0013] Further, the vertical beam assembly further comprises a heat-conducting plate arranged between the cover plate and the cover shell and fixed to the cover shell by a heat-conducting adhesive, and the heating wire is fixed to one side of the heat-conducting plate facing the cover plate.

[0014] Further, the heating wire is made of a positive temperature coefficient material.

[0015] The application also provides a refrigerator comprising a cabinet defining a storage compartment having a front opening, a pair of door body assemblies comprising a first door body and a second door body respectively pivotably arranged at two sides of the front opening of the storage compartment to open or close the storage compartment, and any one of the vertical beam assemblies as described above, which is integrally pivotably mounted at one side of the first door body away from the pivot center of the first door body and abuts against the second door body when the first door body and the second door body are closed to close the gap between the first door body, the second door body and the cabinet.

[0016] Further, the storage compartment is configured as a freezing compartment; and the cabinet is further configured with a refrigerating compartment, an opening of the refrigerating compartment is provided with a refrigerating door body, and a refrigerating vertical beam assembly is pivotably arranged on the refrigerating door body; wherein the overall arrangement density of the heating wire of the refrigerating vertical beam assembly is less than the overall arrangement density of the heating wire of the vertical beam assembly of the freezing compartment.

[0017] The vertical beam assembly for the refrigerator door body and the refrigerator of the application are particularly suitable for the door body of the freezing compartment. Since the internal temperature of the freezing compartment is relatively low and the temperature difference between the inside and the outside is large, the temperature influence of the gap between the two ends of the vertical beam assembly and the cabinet on the vertical beam assembly is particularly obvious, and the temperature of the two ends of the vertical beam assembly is obviously lower than the temperature of the middle part of the vertical beam assembly. By arranging the heating wire on the vertical beam assembly to have a greater arrangement density at the two ends than at the middle part, the heating wire releases more heat at the two ends of the vertical beam assembly, thereby eliminating the temperature influence of the gap between the two ends of the vertical beam assembly and the cabinet on the two ends of the vertical beam assembly, and further improving the surface temperature uniformity of the vertical beam assembly.

[0033] In Figure 5 In order to better show the structure of the heating wire 130, the cover plate 120 located in front of the heating wire 130 is hidden in the above figure.

[0034] The present embodiment first provides a vertical beam assembly 100 for a refrigerator 20 door body, which can generally include a vertical beam body 110, a cover plate 120, and a heating wire 130.

[0035] The cover plate 120 is buckled on the vertical beam body 110 and defines a heating cavity 121 with the vertical beam body 110; the heating wire 130 is arranged in the heating cavity 121 and is configured to have a higher arrangement density at the sections of the two ends of the vertical beam body 110 than at the section of the middle of the vertical beam body 110.

[0036] In the scheme of the embodiment, the arrangement density of the heating wire 130 at the two ends of the vertical beam body 110 is higher than that at the middle of the vertical beam body 110, that is, the arrangement density of the sections L1 and L2 of the heating wire 130 is higher than that of the section L3. Figures 1-5

[0037] In the scheme of the embodiment, the arrangement density of the heating wire 130 at the two ends of the vertical beam body 110 is higher than that at the middle of the vertical beam body 110, that is, the arrangement density of the sections L1 and L2 of the heating wire 130 is higher than that of the section L3.

[0038] The sections of the heating wire 130 at the two ends of the vertical beam body 110 are arranged to extend in a meandering manner along the length direction of the vertical beam body 110; and the section of the heating wire 130 at the middle of the vertical beam body 110 is arranged to extend in a straight line along the length direction of the vertical beam body 110.

[0039] In the scheme of the embodiment, the arrangement density of the heating wire 130 at the two ends of the vertical beam body 110 is higher than that at the middle of the vertical beam body 110, that is, the arrangement density of the sections L1 and L2 of the heating wire 130 is higher than that of the section L3. Figures 1-5 In the scheme of the embodiment, the arrangement density of the heating wire 130 at the two ends of the vertical beam body 110 is higher than that at the middle of the vertical beam body 110, that is, the arrangement density of the sections L1 and L2 of the heating wire 130 is higher than that of the section L3.

[0040] In other embodiments, the heating wire 130 can also extend in a wave shape along the length direction of the vertical beam body 110 as a whole, wherein the portions of the heating wire 130 at the two ends of the vertical beam body 110 are arranged more densely, that is, the distance between the adjacent two wave shapes of the heating wire 130 at the two ends of the vertical beam body 110 is shorter.

[0041] ​In some embodiments, the heating wire 130 can also extend reciprocally along the length direction of the vertical beam body 110, wherein the arrangement density of the reciprocally extending heating wire 130 at the two ends of the vertical beam body 110 is greater than the arrangement density of the heating wire 130 in the middle of the vertical beam body 110.

[0042] The arrangement density of the heating wire 130 at the first end 111 of the vertical beam body 110 is greater than the arrangement density of the heating wire 130 at the second end 112 of the vertical beam body 110; wherein the first end 111 of the vertical beam body 110 is arranged near one end of the bottom of the door body of the refrigerator 20, and the second end 112 of the vertical beam body 110 is arranged near one end of the top of the door body of the refrigerator 20.

[0043] Referring to Figure 5 In the scheme of the present embodiment, the arrangement density of the heating wire 130 at the first end 111 of the vertical beam body 110 is greater than the arrangement density of the heating wire 130 at the second end 112 of the vertical beam body 110, that is, the arrangement density of the segment L1 of the heating wire 130 is greater than the arrangement density of the segment L2 of the heating wire 130.

[0044] The sinking of cold air in the storage compartment 210 will further exacerbate the temperature difference between the top and bottom of the storage compartment 210, affecting the temperature of the vertical beam assembly 100, so that the temperature at the bottom end is lower than the temperature at the top end. Therefore, in order to avoid the temperature at the bottom end of the vertical beam assembly 100 being too low to produce condensation, more heat needs to be provided to the bottom end of the vertical beam assembly 100.

[0045] In the scheme of the present embodiment, by arranging the arrangement density of the segment L1 of the heating wire 130 to be greater than the arrangement density of the segment L2, the heating wire 130 at the bottom end of the vertical beam assembly 100 can release more heat, thereby eliminating the temperature influence of the sinking of cold air in the storage compartment 210 of the refrigerator 20 on the bottom end of the vertical beam assembly 100, and further improving the surface temperature uniformity of the vertical beam assembly 100.

[0046] The length of the heating wire 130 extending meanderingly at the first end 111 of the vertical beam body 110 is greater than the length of the heating wire 130 extending meanderingly at the second end 112 of the vertical beam body 110; wherein the first end 111 of the vertical beam body 110 is arranged near one end of the bottom of the door body of the refrigerator 20, and the second end 112 of the vertical beam body 110 is arranged near one end of the top of the door body of the refrigerator 20.

[0047] Referring to Figure 5 In the scheme of the present embodiment, the length of the heating wire 130 extending meanderingly at the first end 111 of the vertical beam body 110 is greater than the length of the heating wire 130 extending meanderingly at the second end 112 of the vertical beam body 110, that is, the length of the segment L1 of the heating wire 130 is greater than the length of the segment L2 of the heating wire 130.

[0048] The scheme of the embodiment can also improve the heat generation of the heating wire 130 at the end of the vertical beam assembly 100 close to the bottom of the door body of the refrigerator 20, thereby eliminating the temperature influence of the cold air sinking in the storage compartment 210 of the refrigerator 20 on the bottom end of the vertical beam assembly 100, and further improving the surface temperature uniformity of the vertical beam assembly 100.

[0049] The vertical beam body 110 can generally include a bottom shell 113 and a cover shell 114.

[0050] The cover shell 114 is buckled on the bottom shell 113, and the bottom shell 113 and the cover shell 114 define a foaming space 115 for filling a thermal insulation layer, and define a heating cavity 121 with the cover plate 120.

[0051] In the scheme of the embodiment, the cover shell 114 of the vertical beam body 110 forms the foaming space 115 and the heating cavity 121 with the bottom shell 113 and the cover plate 120, respectively, and the foaming space 115 for filling the thermal insulation layer is arranged in the vertical beam assembly 100, thereby improving the heat preservation and insulation performance of the vertical beam assembly 100.

[0052] In the scheme of the embodiment, the foaming space 115 is arranged between the heating cavity 121 and the storage compartment 210, which on the one hand reduces the temperature influence of the cold air in the storage compartment 210 on the vertical beam assembly 100, so that the vertical beam assembly 100 can be better maintained above the dew point temperature under the heating of the heating wire 130, and the surface of the vertical beam assembly 100 is avoided to produce condensation; on the other hand, the temperature influence of the heating wire 130 on the storage compartment 210 is reduced, the excessive heat load of the heating wire 130 on the storage compartment 210 is avoided, and the energy consumption of the refrigerator 20 is further reduced.

[0053] One end of the vertical beam body 110 is also provided with a pouring hole 116 for pouring the foaming material forming the thermal insulation layer into the foaming space 115.

[0054] In the scheme of the embodiment, the pouring hole 116 is arranged at the bottom end of the vertical beam assembly 100, thereby ensuring the normal filling of the thermal insulation layer in the foaming space 115 while improving the aesthetics of the vertical beam assembly 100.

[0055] The vertical beam assembly 100 can also include a heat-conducting plate 122 arranged between the cover plate 120 and the cover shell 114 and fixed to the cover shell 114 by heat-conducting glue, and the heating wire 130 is fixed to one side of the heat-conducting plate 122 facing the cover plate 120.

[0056] The scheme of the embodiment fixes the heat-conducting plate 122 on the shell 114 by using heat-conducting glue, and fixes the heating wire 130 on the heat-conducting plate 122, so that the heating wire 130 is shaped, and the heat-conducting performance of the heat-conducting plate 122 is used to further improve the overall temperature uniformity of the vertical beam assembly 100. In some preferred embodiments, the heat-conducting plate 122 can be made of aluminum foil material.

[0057] The heating wire 130 is made of positive temperature coefficient material. The positive temperature coefficient material refers to a material whose resistance value changes in direct proportion to temperature, that is, the higher the temperature, the greater the resistance value, and the lower the temperature, the smaller the resistance value. The heating wire 130 can select a material with a temperature coefficient that meets the anti-condensation heating requirements according to actual needs, that is, to ensure that the heat output does not cause the heating temperature of the vertical beam assembly 100 to reach the preset limit.

[0058] When the heating wire 130 is in a low-temperature environment (i.e., the overall temperature of the vertical beam assembly 100 is low), the resistance of the heating wire 130 decreases due to the influence of the ambient temperature. At this time, the input voltage remains unchanged, and the heating power of the heating wire 130 increases, thereby accelerating the temperature rise of the vertical beam assembly 100 and avoiding condensation of the vertical beam assembly 100.

[0059] When the heating wire 130 is in a high-temperature environment (i.e., the overall temperature of the vertical beam assembly 100 is higher than a certain set threshold), the resistance of the heating wire 130 increases due to the influence of the ambient temperature. At this time, the input voltage remains unchanged, and the heating power of the heating wire 130 decreases, thereby avoiding excessive heating of the heating wire 130 that causes the temperature of the vertical beam assembly 100 to be too high, avoiding excessive heat load of the vertical beam assembly 100 on the storage compartment 210, ensuring the refrigeration effect of the refrigerator 20, and further reducing energy consumption.

[0060] The scheme of the embodiment is that the heating wire 130 is made of positive temperature coefficient material, so that the heating efficiency of the heating wire 130 can automatically change with the change of the ambient temperature, and the heating efficiency of the heating wire 130 always matches the ambient temperature, thereby simplifying the working mode of the heating wire 130 and avoiding excessive heating of the heating wire 130, thereby saving energy consumption.

[0061] In addition, in other embodiments, a temperature sensor can also be arranged in the vertical beam assembly 100 to collect the surface temperature of the vertical beam assembly 100. When the surface temperature of the vertical beam assembly 100 is lower than the dew point temperature (i.e., there is a risk of condensation in the vertical beam assembly), the heating wire 130 is controlled to start heating.

[0062] Generally, the temperature of the freezing chamber is much lower than that of the refrigerating chamber, and the temperature difference between the inside and outside of the freezing chamber is much larger than that of the refrigerating chamber. Therefore, the risk of condensation of the vertical beam assembly 100 of the freezing chamber is much larger than that of the refrigerating chamber, and the temperature of the two ends of the vertical beam assembly 100 of the freezing chamber is more likely to be lower than the temperature of the middle part of the vertical beam assembly 100 of the freezing chamber due to the influence of the low-temperature cold air leaking from the two ends of the vertical beam assembly 100 of the freezing chamber. That is, the problem of uneven temperature distribution of the vertical beam assembly 100 of the freezing chamber is more obvious and serious than that of the refrigerating chamber.

[0063] In addition, since the temperature of the freezing chamber is lower, when the refrigeration system of the freezing chamber is temporarily stopped, the sinking of the cold air in the freezing chamber will further increase the temperature difference between the upper and lower parts of the freezing chamber, that is, the temperature of the lower end of the vertical beam assembly 100 will be lower than that of the upper end of the vertical beam assembly 100, thereby further increasing the unevenness of the surface temperature of the vertical beam assembly 100.

[0064] The vertical beam assembly 100 of the present embodiment is particularly suitable for the door body of the freezing chamber. By arranging the heating wire 130 with the above-mentioned arrangement of high density at the two ends and low density in the middle part and the density at the bottom end being greater than that at the top end on the vertical beam assembly 100, the temperature influence of the cold air leaking from the two ends of the vertical beam assembly 100 and the sinking of the cold air in the freezing chamber on the vertical beam assembly 100 is effectively eliminated, thereby improving the surface temperature uniformity of the vertical beam assembly 100 of the freezing chamber.

[0065] Figure 6 FIG. 1 is a structural schematic diagram of a refrigerator 20 according to an embodiment of the present application. Figure 7 FIG. 2 is a structural schematic diagram of the refrigerator 20 when a first door body 310 of the refrigerator 20 is in a closed state according to an embodiment of the present application.

[0066] In Figure 7 In FIG. 3, in order to better show the cooperation relationship between the vertical beam assembly 100 and the first door body 310 of the refrigerator 20, the second door body 320 located on the right side of the refrigerator 20 is hidden.

[0067] The present embodiment also provides a refrigerator 20, which generally can include a cabinet 200, a pair of door body assemblies 300, and any one of the above-mentioned vertical beam assemblies 100.

[0068] The box 200 defines a storage compartment 210 having a front opening; the pair of doors assembly 300 includes a first door 310 and a second door 320 respectively pivotably arranged at two sides of the front opening of the storage compartment 210 to open or close the storage compartment 210; the vertical beam assembly 100 of any one of the above embodiments is integrally rotatably mounted at a side of the first door 310 away from the pivot center of the first door 310 and abuts against the second door 320 when the first door 310 and the second door 320 are closed to close the gap between the first door 310, the second door 320 and the box 200.

[0069] The scheme of the present embodiment avoids the condensation on the surface of the vertical beam assembly 100 and further improves the surface temperature uniformity of the vertical beam assembly 100 and reduces the energy consumption by arranging the vertical beam assembly 100 with the heating wire 130 having the specific arrangement rule on the first door 310 of the refrigerator 20 while ensuring the sealing effect between the pair of doors assembly 300 and the box 200 of the refrigerator 20.

[0070] In the scheme of the present embodiment, the refrigerator 20 is further provided with a power supply (not shown in the figure), and the end of the heating wire 130 extends out of the vertical beam assembly 100 through the cover 114 and is connected to the power supply to obtain the energy required for work.

[0071] The storage compartment 210 is configured as a freezing compartment; and the box 200 is further configured with a refrigerating compartment, and the refrigerating compartment is provided with a refrigerating door at the opening, and the refrigerating door is pivotably provided with a refrigerating vertical beam assembly; wherein the overall arrangement density of the heating wire 130 of the refrigerating vertical beam assembly is less than the overall arrangement density of the heating wire 130 of the vertical beam assembly 100 of the freezing compartment.

[0072] The refrigerator 20 can generally define one or more storage compartments 210, and the storage compartments 210 can be classified into refrigerating compartments, freezing compartments, variable-temperature compartments and the like according to their functions.

[0073] In the scheme of the embodiment, the refrigerator 20 has two storage compartments 210 arranged in an up-down manner, which are a refrigeration compartment and a freezing compartment. The overall arrangement density of the heating wires 130 in the refrigeration vertical beam assembly arranged at the opening of the refrigeration compartment is less than the overall arrangement density of the heating wires 130 in the vertical beam assembly 100 arranged at the opening of the freezing compartment. In the scheme of the embodiment, the overall arrangement density of the heating wires 130 is set to be suitable for the working temperature of the corresponding storage compartment 210, so that the heating wires 130 arranged at the openings of different storage compartments 210 can keep the vertical beam assembly 100 above the dew point temperature without causing heat waste, thereby avoiding condensation of the vertical beam assembly 100 and further reducing energy consumption and improving user experience.

[0074] In the scheme of the embodiment, the arrangement of the heating wires 130 in the vertical beam assembly 100 is specially set, so that the heating amount of the heating wires 130 at both ends is greater than the heating amount of the heating wires 130 in the middle part, thereby eliminating the temperature influence of the gap between the vertical beam assembly 100 and the cabinet 200 on the vertical beam assembly 100, improving the surface temperature uniformity of the vertical beam assembly 100, and further solving the condensation problem at both ends of the vertical beam assembly 100 and the overheating problem in the middle part of the vertical beam assembly 100.

[0075] In the scheme of the embodiment, the arrangement density of the heating wires 130 at the bottom of the vertical beam assembly 100 is greater than the arrangement density of the heating wires 130 at the top, so that the heating amount of the heating wires 130 at the bottom of the vertical beam assembly 100 is greater than the heating amount of the heating wires 130 at the top, thereby eliminating the temperature influence of the cold air sinking in the storage compartment 210 on the bottom of the vertical beam assembly 100, and further improving the surface temperature uniformity of the vertical beam assembly 100.

[0076] In the scheme of the embodiment, the arrangement density of the heating wires 130 corresponding to different storage compartments 210 is set to be different, so that the arrangement density of the heating wires 130 corresponding to the storage compartment with a higher temperature range is greater, and the arrangement density of the heating wires 130 corresponding to the storage compartment 210 with a lower temperature is smaller, so that the heating amount of the heating wires 130 is suitable for the temperature of the storage compartment 210, and under the premise of ensuring that the vertical beam assembly 100 does not produce condensation, the heat loss caused by excessive heating of the heating wires 130 and the increase of the thermal load of the storage compartment 210 are avoided, thereby reducing the energy consumption of the refrigerator 20.

[0077] At this point, those skilled in the art will appreciate that although specific exemplary embodiments of the application have been described herein, the present application also encompasses many other variations or modifications in accordance with the principles of the application as set forth above. Accordingly, the scope of the present application should be understood to include all such variations and modifications.
