Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to an electric double-air door installation structure for a refrigerator and a refrigerator. Background Art

[0002] A refrigerator's electric damper is a motor-controlled variable vent designed based on thermal principles. When the temperature inside the refrigerator rises, the damper automatically opens, allowing cool air to flow through, maintaining a low temperature. When the temperature drops to the set point, the damper automatically closes, preventing cool air from escaping and maintaining a constant temperature inside the refrigerator. Similarly, an electric dual damper, with a single motor controlling the opening and closing of two dampers, can independently control the temperature of two compartments.

[0003] During refrigerator use, the defect of the electric double damper causing cold air leakage can easily cause the temperature of the two compartments to interfere with each other. That is, when only one compartment is hot and needs to be cooled, this cold air leaks through the assembly gap of the damper into the other compartment, causing the temperature of the other compartment to drop uncontrollably.

DETAILED DESCRIPTION

[0033] A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] In order to achieve the above purpose, the embodiment of the present utility model adopts the following technical solutions: Figure 1 、 Figure 2 、 Figure 6 A refrigerator electric double damper installation structure includes a double damper assembly 10, which includes a motor housing 110 and damper ducts 120 arranged on both sides of the motor housing 110. A motor is arranged in the motor housing 110. In order to facilitate the assembly of the motor housing 110, an assembly fillet 111 is provided on the side edge of the motor housing 110. At the same time, in order to facilitate the control of the opening and closing of the damper duct 120 by the motor in the motor housing 110, an air outlet 121 is provided in the damper duct 120, and a damper 122 driven by the motor in the motor housing 110 is provided at the air outlet 121. When in use, the opening and closing and the size of the opening and closing of the damper 122 can be controlled by the motor. The electric double damper mounting structure of the refrigerator of the present invention also includes a partition member 20, which is arranged between the motor housing 110 of the double damper assembly 10 and the assembly surface of the refrigerator air duct. The partition member 20 can fill the assembly gap between the motor housing 110 and the assembly surface of the refrigerator air duct, so as to realize the independent circulation of cold air along each damper air duct 120, so as to prevent the cold air from flowing through the aforementioned assembly gap to form a cold air leakage path, thereby avoiding adverse effects on the compartment temperature in the refrigerator.

[0035] It should be noted that the partition member 20 can be set on the assembly surface of the motor housing 110 and the outer periphery of the refrigerator air duct. In this way, the motor housing 110 and the damper air duct 120 can be sealed from the outside, thereby reducing the possibility of an assembly gap forming on the periphery of the double damper assembly 10.

[0036] Reference Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 Furthermore, the partition member 20 includes a mounting cover 210 arranged on the outside of the double air door assembly 10, and a chamber corresponding to the air door duct 120 is provided in the inner cavity of the mounting cover 210, and the mounting cover 210 includes a bottom wall 2101 and a side wall connected to the peripheral side of the bottom wall 2101, and a vent is opened on the bottom wall 2101, which is connected to the chamber and corresponds to the air outlet 121 of the double air door assembly 10, so that cold air can smoothly enter the refrigerator air duct through the air outlet 121 and the vent corresponding to the air outlet 121.

[0037] In addition, a mounting fillet 212 is provided on the bottom wall 2101 of the mounting cover 210 for fitting with the mounting fillet 111 on the motor housing 110. In some embodiments, such as Figure 6 As shown, the side surface of the motor housing 110 that fits with the bottom wall 2101 of the mounting cover 210 includes two long side ridges and two wide side ridges. The two wide side ridges may have assembly fillets 111. The bottom wall 2101 is respectively provided with two installation fillets 212 that fit with the assembly fillets 111. Specifically, as Figure 7 As shown, the installation fillet 212 has an arc-shaped fillet surface, and both sides of the arc-shaped fillet surface extend to the two adjacent side surfaces of the installation cover 210 respectively. When the installation cover 210 is connected to the double damper assembly 10, the arc-shaped fillet surface of the installation fillet 212 fits with the assembly fillet 111 of the motor housing 110, and the two side surfaces connected to the arc-shaped fillet surface fit with the two side surfaces of the wide side ridges of the motor housing 110 respectively, so that the installation cover 210 wraps the assembly fillet 111 through the installation fillet 212, thereby avoiding the generation of a cold air leakage path between the installation cover 210 and the motor housing 110.

[0038] In some embodiments, at least one first rib 2102 is provided on the bottom wall 2101 of the mounting cover 210, protruding toward the air outlet 121. The first rib 2102 extends along the width of the inner cavity of the mounting cover 210 and is aligned with the outer wall of the motor housing 110. Specifically, in this embodiment, there can be two first ribs 2102, one located on either side of the motor housing 110. When in use, the two first ribs 2102 are aligned with two opposing outer walls of the motor housing 110. The first ribs 2102 are positioned between the wide side of the damper 122 and the sidewall of the motor housing 110, filling the gap between the wide side of the damper 122 and the motor housing 110, further preventing cold air leakage from the dual damper assembly 10. In this manner, the combined action of the mounting fillet 212 and the first ribs 2102 allows for effective assembly of the mounting cover 210 with the motor housing 110, further preventing the formation of an assembly gap on the outside of the motor housing 110.

[0039] In some other embodiments, a mounting fillet 212 is provided at the connection between the first rib 2102 and the bottom wall 2101 .

[0040] Specifically, the two long side ridges of the motor housing 110 can have assembly fillets 111, and the mounting cover 210 is respectively provided with mounting fillets 212 matching the assembly fillets 111. At this time, the mounting fillets 212 are arranged at the connection between the first rib 2102 and the bottom wall 2101, that is, the arc-shaped fillet surface of the mounting fillet 212 is respectively connected to the first rib 2102 and the bottom wall 2101 on both sides. When the mounting cover 210 is connected to the double damper assembly 10, the arc-shaped fillet surface is fitted with the assembly fillet 111 of the motor housing 110, and the first rib 2102 and the bottom wall 2101 are respectively fitted with the side surfaces on both sides of the long side ridges of the motor housing 110, so that the mounting cover 210 wraps the assembly fillet 111 through the first rib 2102 and the mounting fillet 212, further avoiding the formation of a cold air leakage path between the mounting cover 210 and the motor housing 110.

[0041] Furthermore, at least one second rib 2103 protruding toward the air outlet 121 is provided on the bottom wall 2101. The second rib 2103 extends along the length direction of the inner cavity of the mounting cover 210. The second rib 2103 is placed between the long side of the air outlet 121 and the side wall of the mounting cover 210. Furthermore, the second rib 2103 is located between the long side of the air outlet 121 and the side wall of the damper duct 120 corresponding to the air outlet 121, and is used to fill the gap between the long side of the air outlet 121 and the side wall of the damper duct 120, further preventing the double damper assembly 10 from leaking cold air. In some embodiments, such as Figure 7 As shown, the two long sides of each air outlet 121 may be respectively provided with second ribs 2103 .

[0042] Specifically in this embodiment, the second rib 2103 can be located on both sides of the first rib 2102, and the second rib 2103 on each side is formed in a form symmetrically distributed along the length direction of the inner cavity of the installation cover 210, and the second rib 2103 is in contact with the outer wall of the damper duct 120. In this way, when the installation cover 210 is assembled with the dual damper assembly 10, the first rib 2102 and the second rib 2103 form a receiving cavity in the inner cavity of the installation cover 210 that respectively cooperates with the motor housing 110 and the damper duct 120. The receiving cavity is divided into a first cavity that cooperates with the motor housing 110 and a second cavity that cooperates with the damper duct 120, and the second cavity is located on both sides of the first cavity. In this way, when the installation cover 210 is covered on the outside of the dual damper assembly 10, the motor housing 110 and the damper duct 120 are respectively placed in the corresponding first cavity and second cavity to obtain a better installation effect; it should be noted that the aforementioned installation fillet 212 is arranged inside the first cavity.

[0043] Furthermore, in order to achieve effective installation of the mounting cover 210 and the dual damper assembly 10, a buckle 220 is provided on the side wall of the mounting cover 210 to engage with the dual damper assembly 10. When in use, the mounting cover 210 is placed on the periphery of the dual damper assembly 10 and can be engaged with the dual damper assembly 10 using the buckle 220 to achieve fixed installation of the two.

[0044] Specifically in this embodiment, the buckle 220 is arranged on two opposite outer side walls in the length direction of the mounting cover body 210, and the buckle 220 includes an extension portion extending outward from the mounting cover body 210 and a buckle portion arranged at one end of the extension portion away from the mounting cover body 210. It should be noted that the extension portion has a certain elasticity, so that when the mounting cover body 210 contacts the damper duct 120, it can be opened in a small range under the action of the damper duct 120, and finally the buckle portion is located at the bottom of the damper duct 120, so as to realize the buckle of the mounting cover body 210 with the double damper assembly 10.

[0045] Furthermore, the outer wall of the mounting cover 210 is further provided with a wiring assembly, which includes at least one first wiring member 231 and a second wiring member 232 alternately arranged in the length direction of the outer wall of the mounting cover 210. When the number of the first wiring member 231 and the second wiring member 232 is both multiple, such as Figure 8 As shown, multiple first wiring members 231 and multiple second wiring members 232 are arranged in rows on the outer wall of the mounting cover 210, and there is a certain height difference between the row formed by the multiple first wiring members 231 and the row formed by the second wiring members 232, that is, there is a certain gap between the rows formed by the first wiring members 231 and the second wiring members 232, and the gap can be used to install and position the motor wires.

[0046] Further, such as Figure 8 As shown, the outer side of the first wiring member 231 can be bent toward the second wiring member 232, that is, bent downward to form a wire blocking plate. When the motor wire is led out, it is placed in the wire blocking plate to achieve further positioning of the motor wire.

[0047] Reference Figure 2As the preferred technical solution of this embodiment, the refrigerator electric double air door mounting structure also includes a partition 30. Furthermore, the partition 30 includes a partition upper cover 310, a partition lower cover 320 and a partition foam 330. The partition lower cover 320 is matched with the partition upper cover 310, that is, the two can be buckled together to form a complete shell structure. A cavity is formed inside the shell structure, and the partition foam 330 is arranged in the cavity formed by the partition upper cover 310 and the partition lower cover 320, wherein the partition foam 330 is used to install the aforementioned double air door assembly 10 and the partition member 20. Specifically, the partition member 20 includes a mounting cover body 210 provided with a plurality of mounting protrusions, and the plurality of mounting protrusions are provided with fastening holes. The partition member 20 and the partition foam 330 are positioned and installed by connecting fasteners such as screws with the fastening holes and the partition foam 330. It should be noted that in order to facilitate the cold air transmitted through the electric double damper mounting structure of the refrigerator to be transported into the refrigerating chamber 40 through the partition 30, an exhaust outlet corresponding to the ventilation outlet is also opened on the top of the partition upper cover 310. In this way, when in use, after the double damper assembly 10 and the partition member 20 are assembled, they can be set as a whole in the partition foam 330, and the partition foam 330 can then be set between the partition lower cover 320 and the partition upper cover 310, thereby realizing the assembly of the electric double damper mounting structure of the refrigerator.

[0048] The utility model also provides a refrigerator, including a refrigerator duct and the aforementioned refrigerator electric double air door mounting structure, wherein the electric double air door mounting structure includes a partition 30 arranged between the refrigerator compartment 40 and the freezer compartment 50 of the refrigerator, further, the refrigerator duct includes a freezing air duct 60 arranged in the freezer compartment 50 and a refrigeration air duct 80 arranged in the refrigerator compartment 40, the freezing air duct 60 is communicated with the air inlet side of the double air door assembly 10, a temperature-changing drawer 70 is provided at the bottom of the refrigerator compartment 40, the refrigeration air duct 80 is communicated with the air outlet 121 of the double air door assembly 10, a partition member 20 is arranged between the motor housing 110 and the assembly surface of the refrigeration air duct 80, and the refrigeration air duct 80 includes air inlets 60 and 80 respectively connected to the refrigerator compartment 40 and the temperature-changing drawer The sub-air ducts 70 are connected. When in use, the cold air is transported to the double air door assembly 10 through the freezing air duct 60, and the cold air is transported to each sub-air duct along the refrigeration air duct 80 through the air outlet 121 on the double air door assembly 10, and can be transported to the refrigerator compartment 40 and the temperature-changing drawer 70 respectively. Since the refrigeration air duct 80 is assembled above the partition 30, and the aforementioned partition member 20 is provided on the partition 30, the installation fillet 212, the first rib 2102 and the second rib 2103 in the partition member 20 can be closely matched with the shape of the double air door assembly 10 to avoid the formation of an assembly gap, thereby solving the problem of easy cold leakage of the double air door assembly 10, thereby ensuring that the temperature of each compartment of the refrigerator is under accurate and reliable control.
