[0001] This application relates to the field of refrigeration equipment technology, and in particular to a refrigeration air duct assembly and a refrigerator. Background Technology

[0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a household appliance that keeps food or other items at a constant low temperature. The refrigerator's freezer air duct assembly consists of a freezer air duct, a freezer cover, and a fan motor. The freezer air duct and the freezer cover are two large plastic parts. The freezer air duct includes streamlined and non-streamlined areas. The streamlined area mainly provides the path for delivering airflow, and the freezer cover works in conjunction with the freezer air duct to form a complete path.

[0003] Because freezer air ducts occupy a large volume, their material costs are very high, especially for large refrigerators. Material costs can be reduced by shrinking the freezer air ducts, and the structure also facilitates component installation. Summary of the Invention

[0004] This application provides a refrigeration duct assembly and a refrigerator to solve the problem of large refrigeration duct volume and inconvenient installation.

[0005] The first aspect of this application provides a refrigeration air duct assembly, including: a refrigeration air duct, a refrigeration mask, and a fan motor;

[0007] By connecting the mask profile with the air duct profile, the mask streamline area and the air duct streamline area form a complete refrigeration air duct path, which not only reduces the volume of the refrigeration air duct, but also facilitates assembly, thus solving the problem of large volume and inconvenient installation of refrigeration air ducts.

[0013] The return air vents are used to draw air from the freezer compartment back into the evaporator compartment, forming a return air circulation path. There are four return air vents, and they are parallel to each other. This not only increases the return air volume and reduces the possibility of malfunctions causing the system to stop operating, but also ensures that the parallel arrangement of the return air vents prevents them from obstructing each other, facilitating air return.

[0014] Optionally, it also includes several air outlets, which are respectively opened on the first mask streamline area, the second mask streamline area, the third mask streamline area, the fourth mask streamline area and the fifth mask streamline area.

[0015] The air outlet is used to deliver the cooled air from the evaporator into the freezer compartment, thereby lowering the temperature inside the freezer compartment. Several air outlets are evenly distributed in the streamlined area of ​​the faceplate, which allows the cooled air entering the freezer compartment to be more dispersed, resulting in a more uniform temperature inside the freezer compartment.

Detailed Implementation

[0032] The embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described below do not represent all embodiments consistent with this application. They are merely examples of systems and methods consistent with some aspects of this application as detailed in the claims.

[0033] The freezer air duct assembly of a refrigerator consists of a freezer air duct, a freezer cover, and a fan motor. The freezer air duct and freezer cover are two large plastic components. The freezer air duct includes streamlined and non-streamlined areas. The streamlined area primarily provides the path for airflow, while the freezer cover works in conjunction with the freezer air duct to form a complete path. Because the freezer air duct occupies a large volume, its material cost is high, especially for large refrigerators. Reducing the size of the freezer air duct can lower material costs and also make the structure easier to install.

[0034] To address the issue of large refrigeration duct volume and inconvenient installation, see [reference needed]. Figures 1-5 ,in, Figure 1 This is a schematic diagram of the structure of a refrigeration air duct assembly; Figure 2 A schematic diagram of the structure of a refrigeration duct assembly, including a refrigeration mask and a fan motor; Figure 3 This is a schematic diagram of the structure of a refrigeration duct assembly; Figure 4 A schematic diagram of the structure of a refrigeration air duct assembly after it is assembled into the refrigerator body; Figure 5This is a cross-sectional view of a refrigeration air duct assembly assembled into a refrigerator body. This application provides a refrigeration air duct assembly and a refrigerator.

[0035] like Figures 1-3 As shown, some embodiments of this application provide a refrigeration air duct assembly, including: a refrigeration air duct 22, a refrigeration mask 21, and a fan motor 13;

[0036] The edge of the freezing air duct 22 is embedded inside the freezing mask 21; the freezing mask 21 includes a streamlined area 212 and a non-streamlined area 213; both the freezing air duct 22 and the streamlined area 212 are butterfly-shaped structures; the streamlined area 212 and the non-streamlined area 213 are separated by a mask profile 211; the freezing air duct 22 includes a streamlined area 222, and the edge of the streamlined area 222 is provided with a duct profile 221; the mask profile 211 is sleeved with the duct profile 221; the fan motor 13 is disposed inside the streamlined area 212.

[0037] It should be understood that the air duct streamline area 222 refers to the area used to provide a path for delivering air volume; the mask streamline area 212 refers to the area used to cooperate with the air duct streamline area 222 to form a complete path for delivering air volume; the freezing mask 21 can separate the evaporator compartment 02 and the freezing compartment 01 through the mask non-streamline area 213.

[0038] By connecting the mask profile 211 with the air duct profile 221, the mask streamline area 212 and the air duct streamline area 222 form a complete refrigeration air duct path, which not only reduces the volume of the refrigeration air duct 22, but also facilitates assembly, thus solving the problem that the refrigeration air duct 22 has a large volume and is inconvenient to install.

[0039] In some embodiments, the area of ​​the inner wall of the air duct profile 221 is greater than or equal to the area of ​​the outer wall of the mask profile 211; the inner wall of the air duct profile 221 is provided with a plurality of buckles; the outer wall of the mask profile 211 is provided with a plurality of grooves; when the mask profile 211 is sleeved with the air duct profile 221, the buckles engage with the grooves.

[0040] It should be understood that the number of the buckles and the grooves is the same, and when the mask profile 211 is fitted with the air duct profile 221, the positions of each buckle and groove correspond to each other. By engaging the buckles and the grooves, the inner wall of the air duct profile 221 can be more securely fixed to the outer wall of the mask profile 211 and is easier to disassemble.

[0041] In some other embodiments, a plurality of screw holes are provided on the inner wall of the air duct profile 221 and the outer wall of the mask profile 211. The inner wall of the air duct profile 221 and the outer wall of the mask profile 211 are further connected by screws, which also makes the inner wall of the air duct profile 221 and the outer wall of the mask profile 211 more secure and easier to disassemble.

[0042] The side of the air duct profile 221 closest to the mask profile 211 is on a plane; the side of the mask profile 211 closest to the air duct profile 221 is also on a plane; when the mask profile 211 is fitted with the air duct profile 221, the air duct profile 221 and the mask profile 211 can be more tightly joined, reducing the probability of air flowing out from the gap between the air duct profile 221 and the mask profile 211.

[0043] like Figure 2 and Figure 3 As shown, in some embodiments, the fan motor 13 is disposed in the middle of the mask streamlined area 212; the mask streamlined area 212 includes a first mask streamlined area 2121, a second mask streamlined area 2122, a third mask streamlined area 2123, a fourth mask streamlined area 2124, and a fifth mask streamlined area 2125; the first mask streamlined area 2121, the second mask streamlined area 2122, the third mask streamlined area 2123, the fourth mask streamlined area 2124, and the fifth mask streamlined area 2125; The first ends of streamlined region 2124 and the fifth mask streamlined region 2125 are connected to each other; the second ends of the first mask streamlined region 2121 and the second mask streamlined region 2122 are located at the top of the mask streamlined region 212; the second ends of the third mask streamlined region 2123 and the fourth mask streamlined region 2124 are located at the bottom of the mask streamlined region 212; and the second end of the fifth mask streamlined region 2125 is located in the middle of the mask streamlined region 212.

[0044] like Figure 2 As shown, the first mask streamlined area 2121 and the second mask streamlined area 2122 gradually narrow from the top of the mask streamlined area 212 to the position near the fan motor 13; the third mask streamlined area 2123 gradually widens from the bottom of the mask streamlined area 212 to the position near the fan motor 13; the fifth mask streamlined area 2125 is located between the first mask streamlined area 2121 and the fourth mask streamlined area 2124; and a section of the mask profile 211 on the side of the fifth mask streamlined area near the fourth mask streamlined area 2124 forms a straight line in the horizontal direction. The mask streamlined area 212 and the air duct streamlined area 222 facilitate uniform airflow from the fan motor 13 and reduce airflow convection.

[0045] It should be understood that the first mask streamline area 2121, the second mask streamline area 2122, the third mask streamline area 2123, the fourth mask streamline area 2124, and the fifth mask streamline area 2125 are integrally formed structures. The integrally formed structure makes the mask streamline areas 212 without connecting seams, tight and uniform, increasing the stress strength, making them less prone to cracking and reducing gas leakage.

[0046] like Figure 2 As shown, in some embodiments, a return air vent is also included; the return air vent is located at the bottom of the mask streamline area 212; the return air vent includes a first return air vent 31, a second return air vent 32, a third return air vent 33, and a fourth return air vent 34; the first return air vent 31, the second return air vent 32, the third return air vent 33, and the fourth return air vent 34 are parallel to each other; the first return air vent 31 and the second return air vent 32 are respectively connected to the third mask streamline area 2123; the third return air vent 33 and the fourth return air vent 34 are respectively connected to the fourth mask streamline area 2124.

[0047] like Figure 2 As shown, the return air vent is a curved structure with a rectangular cross-section; one side of the first return air vent 31 is close to the side of the refrigeration hood 21, and the first return air vent 31 and the second return air vent 32 are separated by three return air baffles; one side of the fourth return air vent 34 is close to the other side of the refrigeration hood 21. The third return air vent 33 and the fourth return air vent 34 are also separated by three return air baffles. The return air vents are used to draw air from the refrigeration chamber 01 back to the evaporator chamber 02, forming a return air circulation path. The four return air vents are parallel to each other, which not only increases the return air volume and reduces the possibility of malfunction due to one of the return air vents failing, but also ensures that the parallel arrangement of the return air vents does not obstruct each other, facilitating return air.

[0048] In some embodiments, the device further includes an air outlet 4; a plurality of the air outlets 4 are respectively provided on the first mask streamline area 2121, the second mask streamline area 2122, the third mask streamline area 2123, the fourth mask streamline area 2124 and the fifth mask streamline area 2125.

[0049] like Figure 2As shown, there are six air outlets 4, symmetrically arranged in pairs on the cooling mask 21. Each air outlet 4 includes a first air outlet, a second air outlet, a third air outlet, a fourth air outlet, a fifth air outlet, and a sixth air outlet. Specifically, the first air outlet is located in the first mask streamlined area 2121 near the top of the mask streamlined area 212; the second air outlet is located in the second mask streamlined area 2122 near the top of the mask streamlined area 212; the third air outlet is located in the third mask streamlined area 2123 near the bottom of the mask streamlined area 212; the fourth air outlet is located in the fourth mask streamlined area 2124 near the bottom of the mask streamlined area 212; and the fifth air outlet is located in the fifth mask streamlined area 2125. It should be understood that the size of the fifth mask streamlined area 2125 is larger than the size of the fifth air outlet, and the fifth air outlet is located away from the fan motor 13. The fifth mask streamlined area 2125 is used to open the fifth air outlet while minimizing obstruction to gas flow. The sixth air outlet is located at the position of the third mask streamlined area 2123 and is aligned with the fifth air outlet. It should be understood that the dimension of the third mask streamlined area 2123 near the center of the freezing mask 21 is larger than the dimension of the sixth air outlet, and the sixth air outlet is located away from the fan motor 13. The third mask streamlined area 2123 is used to open the fifth air outlet while facilitating gas flow.

[0050] The air outlet 4 is used to send the cold air cooled by the evaporator into the freezer compartment 01, thereby lowering the temperature inside the freezer compartment 01. Several air outlets 4 are evenly arranged on the streamlined area 212 of the mask, which can make the cold air entering the freezer compartment 01 more dispersed and the temperature inside the freezer compartment 01 more uniform.

[0051] In some embodiments, the edge of the non-streamlined area 213 of the mask is provided with a plurality of mounting holes; the mounting holes are threadedly connected to the refrigerator body 00 by screws.

[0052] Two mounting holes are optionally provided, symmetrically arranged on both sides of the non-streamlined area 213 of the faceplate. These mounting holes are used to fix the refrigeration air duct assembly 2 inside the refrigerator body 00, facilitating installation and removal.

[0053] like Figure 4 As shown, some embodiments of this application provide a refrigerator, including: a refrigerator body 00 and a refrigeration air duct assembly 2 having the refrigeration air duct assembly 2 described in the above embodiments of this application; the refrigeration air duct assembly 2 is disposed inside the refrigerator body 00.

[0054] Since the refrigerator has all the beneficial effects of the refrigeration air duct assembly 2 described in the above embodiments, it will not be repeated here.

[0055] like Figure 5 As shown, in some embodiments, a freezer compartment 01 and an evaporator compartment 02 are also included; the freezer duct assembly 2 is disposed in the middle of the freezer compartment 01 and the evaporator compartment 02.

[0056] By placing the refrigeration air duct assembly 2 in the middle of the refrigeration chamber 01 and the evaporator chamber 02, the refrigeration chamber 01 and the evaporator chamber 02 can be separated without the need for additional partition plates, thus saving materials.

[0057] As can be seen from the above technical solutions, this application provides a freezer air duct assembly and a refrigerator. The freezer air duct assembly includes: a freezer air duct 22, a freezer face shield 21, and a fan motor 13; the edge of the freezer air duct 22 is embedded inside the freezer face shield 21; the freezer face shield 21 includes a streamlined area 212 and a non-streamlined area 213; both the freezer air duct 22 and the streamlined area 212 are butterfly-shaped structures; the streamlined area 212 and the non-streamlined area 213 are separated by a face shield profile 211; The refrigeration air duct 22 includes an air duct streamline area 222, the edge of which is provided with an air duct profile 221; the mask profile 211 is sleeved with the air duct profile 221; the fan motor 13 is located inside the mask streamline area 212, forming a complete refrigeration air duct path through the mask streamline area 212 and the air duct streamline area 222, reducing the volume of the refrigeration air duct 22, and separating the evaporator chamber 02 and the refrigeration chamber 01 through the refrigeration mask 21, thereby solving the problem of the large volume of the refrigeration air duct 22 and its inconvenience in installation.

[0058] Similar parts between the embodiments provided in this application can be referred to mutually. The specific implementation methods provided above are only a few examples under the overall concept of this application and do not constitute a limitation on the scope of protection of this application. For those skilled in the art, any other implementation methods extended from the solution of this application without creative effort shall fall within the scope of protection of this application.
