Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator structures, in particular to an air outlet component of a vertical refrigerator. Background Art

[0002] In modern refrigeration technology, vertical freezers are widely used in retail, catering and home industries due to their small footprint and high volume utilization. Vertical freezers are usually used to store food, beverages and other items that need to be refrigerated or frozen to extend their shelf life and maintain the freshness of food. However, traditional vertical freezers have some defects in air circulation and cold air distribution, which in turn affects the refrigeration efficiency of the freezer and the preservation effect of food.

[0003] Generally speaking, the cold air distribution of traditional upright freezers relies on the cold air generated by one or more refrigeration devices inside the freezer. These refrigeration devices are usually located at the top or bottom of the freezer, and spread the cold air inside the freezer through natural convection or auxiliary fans. However, this cold air distribution method often leads to temperature stratification or cold air dead corners inside the freezer, that is, the temperature in some areas of the freezer is higher or lower, so that the food stored in these areas cannot be properly refrigerated.

[0004] For example, in some refrigerator designs, due to the fixed position of the refrigeration components, the cold air may be mainly concentrated on one side of the refrigerator. This causes the food on that side to be at a lower temperature, while the food on the other side may be at a higher temperature due to insufficient cold air. In addition, the placement of items inside the refrigerator will also affect the circulation of cold air. For example, if there are too many items inside the refrigerator, or the items are stacked too loosely, the circulation of cold air may be blocked, resulting in uneven distribution of cold air in certain areas inside the refrigerator.

[0005] In response to the above problems, the industry has been exploring more effective solutions for cold air distribution. For example, some refrigerators use multiple fans to enhance internal air convection, or set up special air guides inside the refrigerator to guide the flow of cold air. Although these solutions have improved the cold air distribution problem to a certain extent, there are still some shortcomings, such as increased energy consumption, equipment costs or operational complexity.

[0015] A positioning strip is fixedly connected to the side wall of the inner container, and a positioning groove which is nested and combined with the positioning portion is formed on the positioning strip.

[0016] In some of the implementations, in order to ensure that the air distribution hood can be stably installed at the bottom of the sealed partition and prevent the cold air input into the air distribution hood from leaking from the connection position between the air distribution hood and the sealed partition, thereby affecting the cooling effect of the goods below, the following technical solution is provided.

[0017] An outward-turned fitting strip is arranged on the top of the air distribution hood, a sealing strip is arranged between the fitting strip and the sealing partition, and the fitting strip is fixed to the sealing partition by a bolt assembly.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figure 1-7 The air outlet assembly of the vertical refrigerator includes an air supply port 2 mounted on the refrigerator inner tank 1 and an air distribution cover arranged in the inner tank 1 and connected to the air supply port 2. A storage rack 4 is also set up in the inner tank 1.

[0036] The top of the air distribution hood is set as an opening structure 31, and a horizontally arranged sealing partition 41 is fixedly connected to the bottom of the shelf 4. The sealing partition 41 is nested and matched with the opening structure 31. The air distribution hood is fixedly installed on the lower surface of the sealing partition 41, and a plurality of evenly distributed air outlet holes 32 are opened at the bottom of the air distribution hood.

[0037] Lower wing strips 21 arranged in the inner liner 1 are fixedly connected to both sides of the inner side end of the air supply port 2, and a splicing notch 22 is opened at the top of the inner side end of the air supply port 2.

[0038] The wind distribution hood is connected to a connecting pipe that docks with the inner end of the air supply port 2. The end of the connecting pipe is fixedly connected to a connecting cover 331 arranged above the connecting pipe. The splicing notch 22 is nested and matched with the connecting cover 331. Upper wing strips 332 that are kept in contact with the lower wing strips 21 are fixedly connected on both sides of the connecting cover 331.

[0039] A plurality of shelves 4 are usually arranged in the inner tank 1 of a vertical refrigerator. When refrigerated goods are placed in the shelves 4 at each layer, the space of the inner tank 1 is blocked and clogged, affecting the downward flow of cold air, resulting in a significant reduction in the refrigeration effect of the shelves 4 at the lower layer.

[0040] The air outlet assembly provided in the present application is installed at the bottom of each layer of the storage rack 4, and can evenly supply cold air to the area below the layer of the storage rack 4, thereby ensuring the refrigeration effect of the goods stored on each layer of the storage rack 4, and improving the storage and refrigeration effect of the goods.

[0041] The air distribution hood is made of bent and welded metal plates (aluminum alloy, iron) to form an open structure 31 on the top, and the connecting pipe 33 is welded to one side of the air distribution hood with the same material to achieve communication between the air distribution hood and the air supply port 2 installed on the inner tank 1.

[0042] The top of the air distribution hood is designed as an open structure, which not only facilitates the processing of the air distribution hood, but also facilitates the maintenance and cleaning of the internal passage of the air distribution hood after the air distribution hood is removed from the sealing partition 41. The multiple groups of air outlet holes 32 evenly arranged on the bottom of the air distribution hood can ensure that the cold air delivered from the air supply port 2 is evenly blown downward into the lower area from each air outlet hole 32.

[0043] The storage rack 4 is usually assembled by embedding downward into the inner liner 1, which is convenient for disassembly and assembly of each layer of the storage rack 4, and the combination of the air supply port 2 and the connecting pipe also follows the downward embedding method. After the air distribution cover and the connecting pipe are assembled into the inner liner 1 together with the storage rack 4, the connecting cover 331 is just above the splicing notch 22 and blocks it. At the same time, the upper wing strip 332 and the lower wing strip 21 are kept in a close arrangement, which can quickly realize the connection between the air supply port 2 and the air distribution cover, and can guide the cold air delivered from the air supply port 2 into the air distribution cover, and then evenly distribute it to the lower area through the air outlet 32 ​​to cool the goods on the lower storage rack 4.

[0044] In order to ensure that the cold air generated by the refrigeration system of the vertical freezer can be evenly distributed in the inner tank 1 and to ensure that the goods on each layer of the shelves 4 are effectively cooled and refrigerated, the following technical solution is provided.

[0045] Multiple layers of air supply ports 2 and storage racks 4 are arranged in the inner tank 1. The outer ends of each group of air supply ports 2 are connected to the air supply duct 23. The air supply duct 23 is arranged between the outer shell of the refrigerator and the inner tank 1, and the air supply duct 23 is connected to the refrigerator refrigeration system.

[0046] The outer end of the air supply port 2 is between the inner tank 1 and the outer shell of the refrigerator (not shown in the accompanying drawings), and each layer of air supply port 2 assembled on the inner tank 1 is connected to the air supply pipe 23, and the air supply pipe 23 is connected to the evaporator, fan, and air supply duct in the refrigeration system of the refrigerator. After the evaporator absorbs heat to evaporate the refrigerant therein, it can increase the temperature of the surrounding air, and the fan blows the surrounding cold air into the air supply duct, and finally transports it to the corresponding connected air distribution hood through the air supply pipe 23 and the air supply port 2.

[0047] In order to ensure that the storage rack 4 can be stably assembled in the inner container 1, to ensure that the storage rack 4 can effectively carry the goods thereon, and to ensure that the sealing partition 41 can be stably installed at the bottom of the storage rack 4, the following technical solution is provided.

[0048] The storage rack 4 includes a hollow main grid plate 42 and a secondary grid plate 43. The secondary grid plate 43 is fixed to the bottom of the main grid plate 42, and the sealing partition 41 is fixed to the bottom of the secondary grid plate 43. The two sides of the main grid plate 42 are provided with downward-turned positioning parts 421, and the front side of the main grid plate 42 is provided with an upward-turned anti-drop part 422.

[0049] A positioning strip 11 is fixedly connected to the side wall of the inner container 1 , and a positioning groove 12 is formed on the positioning strip 11 to be nested and combined with the positioning portion 421 .

[0050] The main grid plate 42 and the auxiliary grid plate 43 are both welded by pasting strips. The main grid plate 42 and the auxiliary grid plate 43 are also assembled by welding. The sealing partition 41 is fixed to the auxiliary grid plate 43 by welding. The main grid plate 42 mainly serves to carry the goods thereon and ensure the stable placement of the goods. At the same time, it is assembled on the positioning strip 11 in the inner liner 1 with the help of the positioning parts 421 on both sides thereof, and the anti-drop part 422 on the front side is flipped upward to prevent the goods placed thereon from falling from here.

[0051] The auxiliary grid plate 43 can be matched with the sealing partition 41 to ensure that the sealing partition 41 can be stably installed on the shelf 4, and then ensure that the air distribution hood is stably installed on the sealing partition 41. The height of the sealing partition 41 is usually designed to be in the range of 20 to 30 mm. While ensuring efficient refrigeration of each layer of goods, it will not cause a significant impact on the refrigerator space.

[0052] In order to ensure that the air distribution hood can be stably installed at the bottom of the sealing partition 41 and prevent the cold air input into the air distribution hood from leaking from the connection position between the air distribution hood and the sealing partition 41, thereby affecting the cooling effect of the goods below, the following technical solution is provided.

[0053] An outward-turned fitting strip 34 is provided on the top of the air distribution hood, a sealing strip 35 is provided between the fitting strip 34 and the sealing partition 41, and the fitting strip 34 is fixed to the sealing partition 41 by a bolt assembly.

[0054] The fitting strip 34 is also formed by bending the air distribution hood, and the setting of the fitting strip 34 and the sealing strip 35 can ensure the air distribution hood and the sealing partition 41 are sealed and connected to each other, so as to prevent the cold air from leaking from the gap at the connection between the two. The fitting strip 34 and the sealing strip 35 are fixed to the sealing partition 41 by a bolt assembly (not shown in the accompanying drawings) provided through the bolt assembly, so as to facilitate the disassembly and assembly thereof, so as to maintain and clean the internal passage of the air distribution hood.

[0055] At the same time, sealing strips are also installed on the upper wing strip 332 , the lower wing strip 21 and the connecting cover 331 to ensure the sealing effect of the connection between the connecting pipe 33 and the air supply port 2 .

[0056] In order to prevent the air distribution hood from evenly distributing the cold air therein to the space below and ensure uniform and efficient cooling of the goods below, the following technical solution is provided.

[0057] The air distribution hood includes a plurality of sections of a transverse air distribution hood 301 and a longitudinal air distribution hood 302 , and the air outlet holes 32 are arranged at the connection nodes of the transverse air distribution hood 301 and the longitudinal air distribution hood 302 .

[0058] The horizontally and vertically distributed air distribution hoods can ensure that they are evenly distributed at the bottom of the rack 4, ensuring that cold air can flow freely in each section of the air distribution hood, and finally output through the air outlet holes 32 at the horizontal and vertical nodes to efficiently cool the goods on the rack 4 below.

[0059] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
