Description

Technical Field

[0001] The present application relates to the field of household appliances, and in particular to a refrigeration appliance. Background Art

[0002] Refrigeration appliances are one of the essential household appliances in people's daily lives. For example, a refrigerator generally has multiple compartments with open fronts, and a door is provided at the front of each compartment. Since the temperature inside the compartment is much lower than the ambient temperature, condensation often forms at the contact between the door and the door frame, which has an adverse effect on the user experience. To avoid condensation at the contact between the door and the door frame, an anti-condensation tube is generally provided inside the sandwich of the door frame, and the waste heat of the refrigerant cooled by the condenser is used to heat the door frame of the refrigerator to prevent condensation.

[0003] When multiple compartments of a refrigerator are composed of multiple separate inner liners and separate doors, multiple corresponding sets of anti-condensation tubes are usually required for the compartments and the beams between the compartments. Welding is needed between the multiple sets of anti-condensation tubes, which increases the complexity of laying the anti-condensation tubes. On the other hand, the laying of the pipelines includes a relatively long ineffective pipe length, and the different temperatures of the compartments cannot be taken into account to fully utilize the waste heat of the refrigerant. In some other cases, if the anti-condensation tubes of multiple compartments are combined into one piece, it is usually necessary to cut a notch on the inner liner near the position of the beam between two compartments for the anti-condensation tube to bend and transition to another compartment, and this design is likely to cause the problem of foam leakage at the cross beam during the foaming of the box body.

[0047] In order to make the technical problems to be solved, technical solutions and beneficial technical effects of the present application clearer and more understandable, the present application will be further described in detail below with reference to the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the protection scope of the present application. And each embodiment may be described with the same or multiple views, but all the features appearing in the same view cannot be interpreted as the features that a single embodiment must have.

[0048] In addition, in the description of the present application, the expression "A and / or B" represents all possible combinations of A and B, such as only A, only B, or A and B.

[0049] As understood by those skilled in the art, refrigeration appliances may include refrigerators, freezers, wine cabinets, etc. For example, a refrigerator generally has a heat-insulated cabinet and a door. The cabinet includes an outer shell, an inner liner, and an insulating layer located between the two. The refrigeration appliance has an evaporative refrigeration system that forms a closed loop. The refrigeration system at least includes a compressor 90, a condenser 91, a dryer filter, and evaporators 106, 306. Of course, the refrigeration appliance may also use other forms of refrigeration systems (such as absorption refrigeration systems, thermoelectric refrigeration systems) in some compartments.

[0050] For the convenience of description, in this embodiment, the width direction of the refrigeration appliance 100 is denoted as the X direction, the depth direction of the refrigeration appliance 100 is denoted as the Y direction, and the height direction of the refrigeration appliance 100 is denoted as the Z direction.

[0051] As Figures 1-3 shown, in order to simply illustrate the inventive concept of the present application, the outer shell of the refrigeration appliance 100 and the door of the refrigeration appliance are omitted. The refrigeration appliance 100 may include a first storage chamber 10 and a second storage chamber 20 provided on one side of the first storage chamber 10. Further, the first storage chamber 10 may be defined by a first inner liner 101. The peripheral wall of the first inner liner 101 extends outwardly from the outside of the first opening 102 of the first storage chamber 10 to form a first peripheral edge 103. The second storage chamber 20 may be defined by a second inner liner 201. The peripheral wall of the second inner liner 201 extends outwardly from the outside of the second opening 202 of the second storage chamber 20 to form a second peripheral edge 203.

[0052] In some specific embodiments, the first inner liner 101 and the second inner liner 102 are generally formed in a rectangular or square shape. Both have an upper side wall, a lower side wall, left and right side walls, and a rear wall. The first inner liner 101 and the second inner liner 102 are distributed vertically or horizontally, and the first opening 102 and the second opening 202 are located on the same plane.

[0053] Further, the temperature of the first storage chamber 10 is lower than the temperature of the second storage chamber 20 to meet the storage requirements of different items in the refrigeration appliance.

[0054] At this time, the refrigeration appliance 100 includes a first dew prevention pipe 40 for preventing condensation on the outer surfaces of the first storage chamber 10 and the second storage chamber 20. The first dew prevention pipe 40 can be bent from a single metal pipe, reducing the number of solder joints and being beneficial to leak prevention.

[0055] The first anti-condensation pipe 40 may include a first anti-condensation pipe section 41 that bends and extends on the first peripheral edge 103 to surround the first opening 102 clockwise or counterclockwise, and a second anti-condensation pipe section 42 that bends and extends on the second peripheral edge 203 to surround the second opening 202 clockwise or counterclockwise. The refrigerant of the refrigeration appliance 100 flows through the first anti-condensation pipe section 41 and the second anti-condensation pipe section 42 in sequence. On the one hand, since the refrigerant flows out of the condenser 91 and enters the first anti-condensation pipe 40, the temperature of the refrigerant at the inlet of the first anti-condensation pipe 40 is relatively high. It flows into the first anti-condensation pipe section to first heat the periphery of the first opening of the relatively low-temperature first storage chamber and then flows into the second anti-condensation pipe section to heat the periphery of the second opening of the relatively high-temperature second storage chamber, which is beneficial to improving the utilization rate of waste heat and the effect of anti-condensation. On the other hand, since the improvement of energy efficiency is beneficial to reducing the need to repeatedly lay anti-condensation pipes around the first opening of the relatively low-temperature first storage chamber, it is beneficial to simplify the complexity of anti-condensation pipe laying.

[0056] It should be noted here that if there is an independently formed partition wall in the first storage chamber 10 or the second storage chamber 20, the first anti-condensation pipe section 41 or the second anti-condensation pipe 42 can bend back and forth and extend from the peripheral edge and be distributed on the front surface of the partition wall facing the door to form a surrounding of the first peripheral edge 103 or the second peripheral edge 203, so as to facilitate anti-condensation of the partition wall.

[0057] Such as Figure 2 and Figures 4-6 As shown, in order to lay the anti-condensation pipe, grooves 105 and 205 are provided on the surfaces of the first peripheral edge 103 of the first inner container 101 and the second peripheral edge 203 of the second inner container 201 facing the door of the refrigeration appliance. The grooves 105 and 205 are used to accommodate the first anti-condensation pipe 40, which is beneficial to the laying and fixing of the anti-condensation pipe.

[0058] Specifically, a first notch 104 is formed on the first peripheral edge 103. The first notch 104 is used to form a channel for laying the first anti-condensation pipe 40, so as to facilitate the first anti-condensation pipe 40 to extend from the position of the condenser 91 into the groove 105.

[0059] Furthermore, the first anti-condensation pipe includes a first inlet section 41a and a first outlet section 41b. At this time, the refrigerant of the refrigeration appliance 100 flows through the first inlet section 41a, the first anti-condensation pipe section 41, and the first outlet section 41b in sequence. It is beneficial to reduce the requirement for laying repeated pipe sections when forming the first anti-condensation pipe section.

[0060] The first notch 104 is configured as a channel for laying the first inlet section 41a and the first outlet section 41b to facilitate forming a closed loop to improve the anti-condensation effect on the relatively low-temperature first storage chamber.

[0061] Among them, the first inlet section 41a passes through the first notch 104 to extend and form the first dew-proof pipe section 41, and the first dew-proof pipe section 41 extends through the first notch 104 to form the first outlet section 41b. As Figure 1 shown, when there is a problem of inconsistent flow directions between the first inlet section 41a or the first outlet section 41b and the first dew-proof pipe section 41, a bend can be formed between the first inlet section 41a or the first outlet section 41b and the first dew-proof pipe 41 to facilitate the forming of the metal pipe.

[0062] Furthermore, the first dew-proof pipe 40 includes a second inlet section 42a and a second outlet section 42b. At this time, the refrigerant of the refrigeration appliance 100 flows through the first inlet section 41a, the first dew-proof pipe section 41, and the first outlet section 41b, the second inlet section 42a, the second dew-proof pipe section 42, and the second outlet section 42b in sequence. This is beneficial to reducing the design requirements for the folded pipe section when forming the first anti-condensation pipe.

[0063] The first notch 104 is configured as a channel for laying the first inlet section 41a and the first outlet section 41b to facilitate the formation of a closed loop to improve the anti-condensation effect on the relatively low-temperature first storage chamber.

[0064] Among them, the second inlet section 42a passes through the second notch 204 to extend and form the second dew-proof pipe section 42, and the second dew-proof pipe section 42 extends through the second notch 204 to form the second outlet section 42b. As Figure 1 shown, when there is a problem of inconsistent flow directions between the second inlet section 42a or the second outlet section 42b and the second dew-proof pipe section 42, a bend can be formed between the first inlet section 41a or the first outlet section 41b and the first dew-proof pipe 41 to facilitate the forming of the metal pipe.

[0065] Similarly, a second notch 204 is formed on the second periphery 203. The second notch 204 is used to form a channel for laying the first dew-proof pipe 40 to facilitate the first dew-proof pipe 40 to extend from the position of the first outlet section 41b into the groove 205.

[0066] As Figure 2 and 3 shown, the first storage chamber 10 and the second storage chamber 20 are connected by a middle beam 60. Generally, the middle beam includes a cover covering the lower side of the first periphery 103 and the upper side of the second periphery 203 to form a closed foaming space.

[0067] Therefore, the position of the first notch 104 is set to avoid the part corresponding to the position of the middle beam 60 on the first periphery 103. The second notch 204 is set to avoid the part corresponding to the position of the middle beam 60 on the second periphery 203. This is to prevent foaming leakage at the middle beam.

[0068] Preferably, in the height direction Z of the refrigeration appliance, the distance between the first notch 104 and / or the second notch 204 and the middle beam is greater than 15 mm, which is conducive to the installation of the cover of the middle beam while preventing the middle beam from leaking foam.

[0069] The refrigeration appliance includes a condenser. The first notch 104 is designed in the middle of the left and right sides of the first peripheral edge 103, closer to the condenser 91; the second notch 204 is designed in the middle of the left and right sides of the second peripheral edge 203, closer to the condenser 91; to achieve the shortest possible pipeline design between the condenser 91 and the first anti-condensation pipe section 41, which is conducive to saving pipelines, avoiding the laying of ineffective pipelines, and improving the utilization rate of waste heat.

[0070] The first notch 104 and the second notch 204 being designed on the same side of the refrigeration appliance 100 is also conducive to avoiding the laying of ineffective pipelines and improving the utilization rate of waste heat.

[0071] Further, referring to the appendix Figure 3 , a connection section 43 extending along the height direction Z of the refrigeration appliance 100 is provided between the first outlet section 41b and the second inlet section 42a. The connection section 43 is located outside the first peripheral edge 103 and the second peripheral edge 203 to facilitate providing space for the laying of the connection section and the second inlet section.

[0072] Further, the connection section 43 is connected to the second inlet section 42a and the first outlet section 41b through a bent pipe. This is conducive to the forming of the first anti-condensation pipe.

[0073] Combined with Figure 1 and Figures 4-6 , in the shown specific embodiment, along the height direction Z of the refrigeration appliance, the refrigerant in the first anti-condensation pipe section 41 flows through the upper peripheral edge and the lower peripheral edge of the first peripheral edge 103 in sequence to form a downward surround of the first peripheral edge 103. Thus, since the first storage chamber 10 can be a freezer and usually the cold air inside it blows out from the upper part of the first storage chamber, the position of the first storage chamber close to the middle beam is more likely to condensate. Therefore, making the refrigerant pass through the upper peripheral edge parallel to the middle beam first is more conducive to improving the energy efficiency utilization rate of waste heat and the anti-condensation effect.

[0074] On this basis, the first inlet section 41a is located on the left or right side of the first peripheral edge 103 and passes through the first notch 104 to provide the first anti-condensation pipe section 41 with an upward extension trend. The first anti-condensation pipe 41 can include a vertical section extending upward from the notch 104, an upper horizontal pipe section parallel to the middle beam 60, a vertical section on the other side opposite to the vertical section, a lower horizontal pipe section, and a vertical section extending upward toward the first notch 104.

[0075] At this time, if the second storage chamber 20 is as Figure 1Located above the first storage chamber, the first outlet section (41b) needs to guide the refrigerant upward to the second dew prevention pipe section 42. Therefore, along the width direction X of the refrigeration appliance, the first outlet section 41b and the first inlet section 41a are arranged in a staggered manner to prevent interference between the first inlet section 41a and the second inlet section 42a or the connection section.

[0076] Similarly, considering that the second storage chamber 20 can be a variable temperature chamber or a special function chamber with a relatively higher temperature than the freezer chamber. Along the height direction of the refrigeration appliance 100, the refrigerant in the second dew prevention pipe section 42 passes through the lower peripheral edge and the upper peripheral edge of the second peripheral edge 203 in sequence to form a surrounding of the second peripheral edge 103 from bottom to top; which is beneficial to improving the energy efficiency utilization rate of waste heat and the dew prevention effect.

[0077] On this basis, the second inlet section 42a is located on the left or right side of the second peripheral edge 203 and passes through the second notch 204 to provide the second dew prevention pipe section 42 with a downward extension trend. The second dew prevention pipe 42 can include a vertical section extending downward from the notch 204, a lower horizontal pipe section parallel to the middle beam 60, another vertical section opposite to the vertical section, an upper horizontal pipe section, and a vertical section extending downward toward the second notch 204.

[0078] It should be noted that although in a specific embodiment shown in the drawings of the present application, the first storage chamber 10 is a freezer chamber, a freezer evaporator 106 is provided in the freezer chamber, and the second storage chamber 20 is a variable temperature chamber or a special function chamber.

[0079] However, in some other embodiments, the first storage chamber 10 can be a variable temperature chamber or a special function chamber, the second storage chamber 20 can be a refrigerating chamber with a relatively higher temperature than the first storage chamber 10, and. The first storage chamber 10 and the second storage chamber 20 can also be arranged side by side. When arranged side by side, it is preferred that the first notch and the second notch are provided in the middle of the upper or lower peripheral edge of the two inner liners.

[0080] In the specific embodiment shown in Figure 1 the refrigeration appliance 100 may further include a third storage chamber 30, the third storage chamber 30 is located above the second storage chamber 20, and the third storage chamber 30 is a refrigerating chamber. For example, a refrigeration evaporator 306 can be provided inside it.

[0081] The third storage chamber 30 is defined by a third inner liner 301; the third inner liner 301 includes a third peripheral edge 303 formed by the outer side of the peripheral wall extending toward the third opening 302 of the third storage chamber 30.

[0082] The refrigeration appliance 100 includes a second dew prevention pipe 50, and the second dew prevention pipe 50 is communicated with the first dew prevention pipe 40. The second dew prevention pipe 50 can be bent from a single metal pipe together with the first dew prevention pipe 40. It is beneficial to reduce the number of solder joints.

[0083] However, considering that the dew prevention tube is a metal part, in order to ensure the flatness of the dew prevention tubes on the three inner liners and reduce the assembly difficulty, it is preferred that the end of the first dew prevention tube 40 is welded to the starting end of the second dew prevention tube 50.

[0084] Similar to the first inner liner 101 and the second inner liner 201, in order to arrange the second dew prevention tube 50, a second groove 305 is provided on the third peripheral edge 303 of the third inner liner 301 facing the surface of the door of the refrigerating appliance, and the second groove 305 is used to accommodate the second dew prevention tube 50.

[0085] Furthermore, a third notch 304 is formed on the third peripheral edge 303 of the third inner liner 301, and the third notch 304 is used to provide a laying channel for the inlet section 50a and the outlet section 50b of the second dew prevention tube 50.

[0086] As Figure 1 shown, the second storage chamber 20 and the second storage chamber 20 are connected by a second middle beam 70. Similar to the middle beam 60, the third notch 304 is provided to avoid the part on the third peripheral edge 303 corresponding to the position of the second middle beam 70.

[0087] When the third storage chamber 30 is used as a refrigerating chamber, considering the usual double-door design of the refrigerating chamber, the upper part of the turning beam of the double doors is more likely to condensate than the lower part. Therefore, along the height direction Z of the refrigerating appliance 100, the refrigerant flow direction in the second dew prevention tube section 50 is to flow through the upper peripheral edge and the lower peripheral edge of the third peripheral edge 303 in sequence to form a surrounding of the third peripheral edge 303 from top to bottom.

[0088] See Figure 7 , in the schematic embodiment of the present application, the refrigeration system of the refrigerating appliance includes a compressor 90, a condenser 91, a first dew prevention tube 40, a second dew prevention tube 50, a back condenser 80, a drying filter, evaporators 106, 306, and a return air pipe 92. The refrigerant flows through the compressor 90, the condenser 91, the first dew prevention tube section 41, the second dew prevention tube section 42, the second dew prevention tube 50, the back condenser 80, the drying filter, the evaporators 106, 306, and the return air pipe 92 in sequence to return to the compressor 90 to form a complete refrigeration cycle.

[0089] Among them, the end of the second dew prevention tube 50 is welded to the inlet of the back condenser 80; the end of the back condenser 80 is welded to the inlet of the drying filter.

[0090] Preferably, the lowest point of the pipeline connecting the end of the first dew prevention tube 40 and the starting end of the second dew prevention tube is higher than or lower than the lowest point of the pipeline connecting the end of the second dew prevention tube 50 and the inlet of the back condenser 80 to facilitate anti-fooling during the assembly process.

[0091] See attached Figure 8, in another specific embodiment, the connecting section 43 is configured with an elbow section 44, and the opening direction of the elbow section 44 faces the center beam 60; this is beneficial to ensuring the assembly flatness of the first anti-condensation tube 40 on the first inner liner 101 and the second inner liner 201, and reducing the assembly difficulty of the first anti-condensation tube 40.
