Description

Technical Field

[0001] This utility model relates to the field of refrigerated compartment technology, specifically a refrigerated compartment with a cold air circulation baffle assembly. Background Technology

[0002] With the rapid development of the cold chain logistics industry, refrigerated containers, as key transportation equipment for ensuring the quality of perishable goods such as fresh food and medicine, have attracted much attention for their refrigeration performance and temperature uniformity.

[0003] A search revealed patent publication number CN208896952U, which discloses a novel lightweight refrigerated and insulated truck body. This design solves the problem of traditional refrigerated and insulated truck bodies struggling to reduce weight while improving insulation performance. The key technical features include: an FRP pultruded frame; a floor assembly fixed to the FRP pultruded frame and supporting the truck body; a top plate and four side plates fixed to the FRP pultruded frame and forming the truck body together with the floor assembly; a supporting frame located at the connection between the truck body and the chassis; and FRP molded corner protectors located at the junctions of the top plate, side plates, and floor assembly; and a door on one of the side plates for opening the truck body. This design maximizes weight reduction while maintaining the required strength, thereby maximizing insulation performance.

[0004] Traditional refrigerated compartments typically use fixed-position exhaust vents for refrigeration circulation. The cold air blown out directly is unevenly distributed within the compartment, resulting in significant temperature differences between different areas. These temperature differences not only affect the storage quality of goods but may also cause some goods to spoil due to excessively high or low temperatures, leading to economic losses. Therefore, a refrigerated compartment with a cold air circulation baffle assembly is designed. Utility Model Content

[0005] In view of the defects or deficiencies of refrigerated compartments with cold air circulation baffle assemblies, the purpose of this utility model is to provide a refrigerated compartment with cold air circulation baffle assemblies, which effectively avoids the situation where the cold air is blown out directly and unevenly distributed in the refrigerated compartment, resulting in a large temperature difference in different areas of the refrigerated compartment.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a refrigerated compartment with a cold air circulation baffle assembly, including a refrigerated compartment body. A partition is provided on one side of the interior of the refrigerated compartment body to divide the internal cavity of the refrigerated compartment body into two chambers, namely a refrigeration chamber and a refrigeration chamber. A refrigeration component for cooling the air is provided inside the refrigeration chamber. An exhaust baffle mechanism is provided above one side of the refrigeration chamber to receive the cold air discharged by the refrigeration component and discharge the cold air into the refrigeration chamber.

[0008] The exhaust guide mechanism is provided with an exhaust guide plate and a drive component for driving one end of the exhaust guide plate to swing up and down.

[0009] The drive assembly is equipped with a turntable, and a cam is arranged in a ring array on one outer wall of the turntable. One corner of the cam is movably connected to the turntable by a movable pin. An arc-shaped slot is opened on the outer wall of the cam. The cam and the turntable are fastened by a tightening screw, and the screw on the tightening screw passes through the arc-shaped slot and is installed in the threaded hole on the turntable.

[0010] Preferably, a second connecting shaft is installed on one side of the front and rear walls of the exhaust guide plate, and the other ends of the two second connecting shafts are respectively installed in sealed bearings on the front and rear walls of the refrigerator body. A first connecting shaft is installed on the other side of the front wall of the exhaust guide plate, and the other end of the first connecting shaft is installed in a bearing at the center of the outer wall of the rotating wheel.

[0011] Preferably, the outer wall of the exhaust guide plate is provided with an air inlet in a rectangular array, the air inlet being connected to the air outlet pipe via a flexible connecting pipe, and the air outlet pipe being arranged in a rectangular array above the outer wall of the partition.

[0012] Preferably, the turntable is located at the front end of the outer circumferential wall of the rotating shaft, and the outer circumferential wall of the turntable is in contact with the outer circumferential wall of the rotating wheel. One end of the rotating shaft is installed in a bearing on the front end wall of the refrigerator body, and the other end of the rotating shaft is connected to the output shaft of the geared motor through a coupling. The geared motor is located inside the heat insulation cover, and the output shaft of the geared motor passes through the front end wall of the heat insulation cover.

[0013] Preferably, the rear end of the heat insulation cover is open, and the heat insulation cover is installed on the rear end wall inside the refrigerator body. The rear end of the heat insulation cover is provided with a rectangular slot, which is connected to the interior of the heat insulation cover. The rectangular slot is opened on the rear end wall of the refrigerator body, and a rainproof louver is provided inside the rectangular slot.

[0014] Preferably, a door is provided on one outer wall of the refrigerator body, and a return air slot is provided between the bottom end of the partition and the bottom end of the refrigerator body, and the return air slot is connected to both the refrigeration chamber and the refrigerator chamber.

[0015] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0016] In this invention, through a series of coordinated structural arrangements, when the refrigerated compartment inside the refrigerated box is used to refrigerate goods, the operator starts the equipment. The refrigeration components cool the air, and the cold air generated by the refrigeration components is delivered through the air outlet pipe to the exhaust guide plate on the exhaust guide mechanism and discharged into the refrigerated compartment. When the geared motor on the drive component starts, it drives the cam on the turntable to rotate. When the cam rotates, it causes one end of the exhaust guide plate on the exhaust guide mechanism to swing up and down to discharge cold air, realizing multi-angle cold air delivery. This effectively avoids the situation where the cold air is blown out directly and unevenly distributed in the refrigerated compartment, resulting in a large temperature difference in different areas of the refrigerated compartment. This ensures improved temperature uniformity in the refrigerated compartment, providing a stable and suitable storage environment for perishable goods such as fresh food and medicine, and significantly reducing the risk of spoilage due to temperature differences.

[0017] In this invention, through the coordination of a series of structures, when the operator needs to adjust the angle of the cold air discharge according to the actual cargo loading situation and the internal space of the refrigerated chamber, the operator rotates the loosening screw fastened between the cam and the turntable. When the cam and the turntable are no longer tightly fastened, the cam can be rotated because one corner of the cam is movably connected to the turntable through a movable pin. After the cam rotates to a certain position, the operator rotates the loosening screw to tighten the cam and the turntable, thus completing the adjustment of the cam. After the cam is adjusted, the distance of the up-and-down swing of one end of the exhaust guide plate will change. The operator can adjust the up-and-down swing distance of one end of the exhaust guide plate by adjusting the cam. The adjustable up-and-down swing distance of one end of the exhaust guide plate can be used to adjust the angle of the cold air discharge according to the actual cargo loading situation and the internal space of the refrigerated chamber, thus enhancing its versatility and practicality.

[0035] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0036] like Figure 1-10 As shown, a refrigerated compartment with a cold air circulation baffle assembly includes a refrigerated compartment body 100. A partition 120 is provided on one side of the interior of the refrigerated compartment body 100 to divide the interior cavity of the refrigerated compartment body 100 into two chambers, namely a refrigeration chamber and a refrigeration chamber. A refrigeration component 300 for cooling the air is provided inside the refrigeration chamber. An exhaust baffle mechanism 200 is provided above one side of the refrigeration chamber to receive the cold air discharged by the refrigeration component 300 and discharge the cold air into the refrigeration chamber.

[0037] The exhaust guide mechanism 200 is provided with an exhaust guide plate 210 and a drive assembly 230 for driving one end of the exhaust guide plate 210 to swing up and down.

[0038] A turntable 232 is provided on the drive assembly 230. A cam 234 arranged in a ring array is provided on one outer wall of the turntable 232. One corner of the cam 234 is movably connected to the turntable 232 by a movable pin. An arc-shaped slot 2341 is provided on the outer wall of the cam 234. The cam 234 and the turntable 232 are fastened by a loosening screw 236. The screw on the loosening screw 236 passes through the arc-shaped slot 2341 and is installed in the threaded hole on the turntable 232. Because one corner of the cam 234 is movably connected to the turntable 232 by a movable pin, and the cam 234 and the turntable 232 are fastened by the loosening screw 236, the operator can adjust the position of the cam 234 by rotating the loosening screw 236.

[0039] A second connecting shaft 213 is installed on one side of the front and rear walls of the exhaust guide plate 210, and the other ends of the two second connecting shafts 213 are respectively installed in the sealed bearings on the front and rear walls of the refrigerator body 100. A first connecting shaft 211 is installed on the other side of the front wall of the exhaust guide plate 210, and the other end of the first connecting shaft 211 is installed in the bearing at the center of the outer wall of the rotor 212.

[0040] The exhaust guide plate 210 has an air inlet arranged in a rectangular array on one side of its outer wall. The air inlet is connected to the air outlet pipe 140 through a flexible connecting pipe 220. The air outlet pipe 140 is arranged in a rectangular array above one side of the outer wall of the partition plate 120.

[0041] The turntable 232 is located at the front end of the outer circumferential wall of the rotating shaft 233, and the outer circumferential wall of the turntable 232 is in contact with the outer circumferential wall of the rotating wheel 212. One end of the rotating shaft 233 is installed in a bearing on the front wall of the refrigerator body 100, and the other end of the rotating shaft 233 is connected to the output shaft of the geared motor 235 through a coupling. The geared motor 235 is located inside the heat insulation cover 231, and the output shaft of the geared motor 235 passes through the front wall of the heat insulation cover 231. When the geared motor 235 starts, it will drive the rotating shaft 233 to rotate. When the rotating shaft 233 rotates, it will drive the turntable 232 to rotate. When the turntable 232 rotates, it will drive the cam 234 to rotate. When the cam 234 rotates, it will exert a reciprocating force on the rotating wheel 212. After the rotating wheel 212 is subjected to the reciprocating force, one end of the exhaust guide plate 210 will swing up and down.

[0042] The rear end of the heat insulation cover 231 is open, and the heat insulation cover 231 is installed on the rear end wall inside the refrigerator body 100. The rear end of the heat insulation cover 231 is provided with a rectangular slot, which is connected to the interior of the heat insulation cover 231. The rectangular slot is opened on the rear end wall of the refrigerator body 100, and a rainproof louver is provided inside the rectangular slot. The heat insulation cover 231 can prevent the temperature inside the refrigerator cavity from affecting the geared motor 235, and also prevent the external temperature from affecting the temperature inside the refrigerator cavity. The rainproof louver and the rectangular slot allow the geared motor 235 to be naturally ventilated and dissipated, and prevent external rainwater from entering the heat insulation cover 231.

[0043] A door 110 is provided on one outer wall of the refrigerator body 100. A return air slot 130 is provided between the bottom end of the partition 120 and the bottom end of the interior of the refrigerator body 100. The return air slot 130 is connected to both the refrigeration chamber and the refrigerator chamber. The setting of the return air slot 130 allows cold air to circulate in the refrigerator chamber and the refrigeration chamber, thus circulating the cold energy.

[0044] Working Principle: When the refrigerated compartment inside the refrigerated container 100 is used to refrigerate goods, the operator starts the equipment. The refrigeration component 300 cools the air. The cold air generated by the refrigeration component 300 is delivered through the air outlet duct 140 to the exhaust guide plate 210 on the exhaust guide mechanism 200 and then discharged into the refrigerated compartment. When the geared motor 235 on the drive component 230 starts, it drives the cam 234 on the turntable 232 to rotate. When the cam 234 rotates, it causes one end of the exhaust guide plate 210 on the exhaust guide mechanism 200 to swing up and down to exhaust cold air. This achieves multi-angle cold air delivery, effectively avoiding uneven distribution of cold air in the refrigerated compartment and the resulting large temperature differences in different areas of the refrigerated compartment. This ensures improved temperature uniformity within the refrigerated compartment, providing a stable and suitable storage environment for perishable goods such as fresh food and medicine, significantly reducing the risk of spoilage due to temperature differences. When the operator needs to adjust the cooling system according to the actual loading situation and refrigeration requirements, the equipment can be adjusted accordingly. When adjusting the angle of the cold air exhaust from the refrigerated compartment, the operator rotates the loosening screw 236 that secures the cam 234 and the turntable 232. This loosens the connection between the cam 234 and the turntable 232. Since a corner of the cam 234 is movably connected to the turntable 232 via a movable pin, the cam 234 can rotate. After the cam 234 rotates to a certain position, the operator rotates the loosening screw 236 to tighten the connection between the cam 234 and the turntable 232, thus completing the adjustment of the cam 234. After adjustment, the distance at which one end of the exhaust guide plate 210 swings up and down changes. The operator adjusts the cam 234 to control the swing distance of one end of the exhaust guide plate 210. This adjustable swing distance allows for adjustment of the angle of the cold air exhaust according to the actual cargo loading and the internal space of the refrigerated compartment, enhancing versatility and practicality.

[0045] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
