[0017] To illustrate the technical content, structural features, achieved objectives, and effects of the application in detail, the technical solutions of the present invention will be described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. In the following description, for illustrative purposes, numerous specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in one or more equivalent arrangements. Furthermore, the various exemplary embodiments may differ, but are not necessarily exclusive. For example, the specific shape, construction, and characteristics of the exemplary embodiments may be used or implemented in another exemplary embodiment without departing from the inventive concept.

[0018] This utility model embodiment provides an air-cooled freezer, such as Figure 1 , 2 As shown, the air-cooled freezer includes a cabinet body 10 with a refrigerator compartment 1 inside, a cabinet door that is rotatably installed on the top of the cabinet body 10, and a refrigeration module 30 for providing cooling capacity to the refrigerator compartment 1.

[0019] The refrigerator compartment 1 is used for storing refrigerated items. Inside the cabinet 10, there is also a refrigeration compartment 2 located on the right side of the refrigerator compartment 1. The refrigeration module 30 is detachably installed in the refrigeration compartment 2. The refrigeration compartment 2 has an air outlet 21 and an air return outlet 22 that connect to the refrigerator compartment 1. The refrigeration module 30 provides cooling to the refrigerator compartment 1 through the air outlet 21, and the cooling is delivered to the refrigerator compartment 1 in the form of cold air through the air outlet 21.

[0020] The cabinet 10 is equipped with an air duct system 40, which includes an air outlet duct 4 connected to the air outlet 21 and a return air duct 5 connected to the return air inlet 22. The return air duct 5 and the air outlet duct 4 are connected at the left end of the refrigerator compartment 1, and together with the refrigeration module 30, they form a refrigeration cycle system that continuously supplies cold air to the refrigerator compartment 1. The air outlet duct 4 surrounds the upper part of the refrigerator compartment 1 and has several exhaust vents 41 facing the refrigerator compartment 1. Each exhaust vent 41 is used for the cold air output by the refrigeration module 30 to pass through and enter the interior of the refrigerator compartment 1. The cold air is blown into the refrigerator compartment 1 from the upper part, and the cold air is deposited downwards due to density, thereby increasing the uniformity of the cold air in the refrigerator compartment 1. The return air duct 5 is arranged at the bottom of the refrigerator compartment 1. The cold air output from the air outlet 21 of the refrigeration module 30 passes through the air outlet duct 4. Some of the cold air enters the refrigerator compartment 1 through several exhaust vents 41 of the air outlet duct 4, while the other part of the cold air returns to the refrigerator compartment 2 where the refrigeration module 30 is located through the return air duct 5 and the return air outlet 22. After being refrigerated by the refrigeration module 30, it is circulated back into the air duct system 40 through the air outlet 21, thereby realizing the continuous circulation of cold energy in the refrigerator compartment 1.

[0021] like Figure 1-3 As shown, a number of air guide plates 6 are provided in the air outlet duct 4. Each air guide plate 6 corresponds to at least one exhaust port 41. At least part of it forms an inclined angle α with the air outlet direction of the air outlet duct 4 to guide at least part of the cold air to the corresponding exhaust port 41, thereby increasing the air volume of the exhaust port 41 and allowing more cold energy to enter the cold storage 1 from the top, thus improving the uniformity of cold energy distribution in the cold storage 1.

[0022] The air duct system 40 includes a base plate 7 fixed to the inner wall of the cabinet 10 and a cover plate 8 that cooperates with the base plate 7. The cover plate 8 and the base plate 7 define an air outlet duct 4. Several exhaust vents 41 are opened on the cover plate 8, and several air guide plates 6 are fixed on the base plate 7. When the cold air output by the cooling module 30 enters the air outlet duct 4 from the air outlet 21, each air guide plate 6 blocks part of the cold air in the path of cold air delivery and guides the blocked part of the cold air to the corresponding exhaust vent 41, thereby enhancing the air outlet effect of each exhaust vent 41 and achieving uniform distribution of cooling capacity.

[0023] Each air guide plate 6 has a connecting portion 61 connected to the base plate 7 and an inclined guide portion 62. The guide portion 62 has a first end 621 and a second end 622 that are far apart from each other. The first end 621 is connected to the connecting portion 61. In the air outlet direction, the first end 621 is located upstream of the second end 622. The distance between the second end 622 and the cover plate 8 is less than the distance between the first end 621 and the cover plate 8, and the second end 622 is adjacent to at least one exhaust port 41. The included angle between the guide portion 62 and the connecting portion 61 is equal to the inclined angle α. The guide portion 62 blocks part of the cold air in the air outlet duct 4 and guides part of the cold air to the corresponding exhaust port 41. In this embodiment of the invention, the inclined angle is 120°-150°, so that the guide portion 62 can gently block and guide part of the cold air in the air outlet duct 4, avoiding noise caused by the cold air impacting the air guide plate 6. The guide plate 5 is a one-piece molded part and is fixedly installed on the base plate 7 by mechanical fasteners.

[0024] There is a gap between the second end 622 and the cover plate 8. The guide part 62 blocks part of the cold air and guides the blocked cold air to the corresponding exhaust port 41. The remaining cold air is transported downstream through the gap between the second end 622 and the cover plate 8. The arrangement of multiple air guide plates 6 in the air outlet duct 4 increases the air volume of each exhaust port 41, avoids the cold air from being concentrated at the bottom of the refrigerator compartment 1, achieves uniform distribution of cold air, and improves the cooling effect and cooling efficiency.

[0025] The refrigeration module 30 includes an evaporator 91, a refrigeration fan 92, a compressor 93, a condenser 94, and a cooling fan 95. When the refrigeration module 30 is installed inside the cabinet 10, the refrigeration fan 92 faces the air outlet 21 to generate cold air into the air outlet duct 4. The refrigeration module 30 also includes an insulation partition 96 installed inside the refrigeration chamber 2. The insulation partition 96 divides the refrigeration chamber 2 into upper and lower cavities. The evaporator 91 and the refrigeration fan 92 are arranged on the upper side of the insulation partition 96, and the compressor 93, the condenser 94, and the cooling fan 95 are arranged on the lower side of the insulation partition 96.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. The scope of protection of this utility model is defined by the appended claims, specification, and their equivalents.
