Description

Technical Field

[0001] This utility model relates to the field of air-cooled cabinet technology, specifically an energy-saving and consumption-reducing air-cooled cabinet. Background Technology

[0002] Currently, refrigeration equipment (refrigerators, freezers, etc.) are common household appliances. Freezers are divided into horizontal freezers and vertical freezers, with horizontal freezers being widely used due to their large storage capacity. Conventional horizontal freezers typically use direct cooling, but frost easily forms inside the freezer during use. To reduce frost buildup inside the freezer, air-cooled horizontal freezers have become increasingly popular.

[0003] Chinese Patent No. CN208920697U discloses an inner liner assembly for a freezer and a horizontal air-cooled freezer, including an inner liner and an air duct assembly. The air duct assembly includes an end cover and two side air ducts. The end cover is located in the inner liner and fixed to its end face, forming an installation cavity between the end cover and the inner liner. A partition is provided in the installation cavity, dividing it into an evaporation cavity and an air supply cavity. The inner air duct cover is located on the inner side of the inner liner, and the outer air duct cover is located on the outer side of the inner liner, forming an air supply channel. A through hole connecting the inner air duct and the air supply channel is opened on the side wall of the inner liner. A second air outlet is opened on the inner air duct cover. The side air ducts are connected to the air supply cavity. This design achieves uniform cold air distribution and improves the cooling effect.

[0004] The aforementioned patent also has some defects. The air outlet of the air-cooled cabinet is close to the cabinet door at the top. After a certain amount of material is placed in the cabinet, the cold air is difficult to flow to the bottom of the cabinet. After testing, it was found that the cabinet has uneven internal temperature and slow cooling. Therefore, we need to propose an energy-saving and consumption-reducing air-cooled cabinet. Utility Model Content

[0005] The purpose of this utility model is to provide an energy-saving and consumption-reducing air-cooled cabinet, which has the advantages of enhancing air-cooling efficiency and making the temperature drop inside the entire cabinet more even, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving and consumption-reducing air-cooled cabinet, comprising a cabinet body, a cabinet door installed on the top of the cabinet body, an inner liner provided inside the cabinet body, and a ventilation component installed at the bottom of the inner liner cavity to achieve ventilation at the bottom of the inner liner;

[0007] An exhaust assembly for discharging cold air is installed on the upper side of one side of the inner liner.

[0008] The cabinet is equipped with a conveying assembly for connecting the ventilation assembly and the exhaust assembly, located inside the inner liner.

[0009] The bottom of the conveying assembly is connected to a conveying pipe.

[0010] Preferably, the ventilation assembly includes a housing, which is installed at the bottom of the inner cavity of the liner, and a support grid is installed on the top of the housing. The inner liner communicates with the interior of the housing through the support grid.

[0011] Preferably, the ventilation assembly includes a ventilation hood disposed above one side of the inner liner, and a ventilation port is provided at the top of one side of the ventilation hood.

[0012] Preferably, the conveying assembly includes a conveying cover, which is L-shaped and installed outside the inner liner and inside the cabinet.

[0013] Preferably, the two ends of the conveying cover are respectively set as an air inlet area and an air outlet area, and one side of the inner liner has an air groove that communicates with the interior of the shell. One end of the conveying cover is connected to the air groove through the air inlet area.

[0014] Preferably, the other end of the conveying hood is connected to the bottom of the exhaust hood through the exhaust area.

[0015] Preferably, the top of the conveying pipe is connected to the bottom of the conveying cover.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In this invention, the cold air inside the shell re-enters the conveying hood through the air duct, and then re-enters the exhaust hood through the conveying hood, thereby achieving cold air circulation and cooling. This fills the entire inner liner with cold air. Because cold air is denser, it descends, creating air convection with the room temperature air inside. The room temperature air rises under the descending force of the cold air, thus creating circulation inside the cabinet. By changing the air duct, the cooling efficiency can be enhanced and energy loss reduced. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 This utility model provides a technical solution: an energy-saving and consumption-reducing air-cooled cabinet, including a cabinet body 1, a cabinet door 2 installed on the top of the cabinet body 1, an inner liner 3 inside the cabinet body 1, and a ventilation component installed at the bottom of the inner liner 3 to achieve bottom ventilation; the ventilation component includes a housing 5, which is installed at the bottom of the inner liner 3, and a support grid 6 is installed on the top of the housing 5. The inner liner 3 is connected to the interior of the housing 5 through the support grid 6. The openings at the top of the support grid 6 facilitate the flow of cold air and also provide support for the materials.

[0027] Furthermore, an exhaust assembly for discharging cold air is installed on the upper side of one side of the inner liner 3; the exhaust assembly includes an exhaust hood 7 located on the upper side of one side of the inner liner 3, and an exhaust port 8 is provided on the top of one side of the exhaust hood 7. By providing the exhaust port 8, cold air can be discharged from the upper side of one side of the inner liner 3 through the exhaust port 8.

[0028] Furthermore, a conveying assembly for connecting the ventilation and exhaust components is installed inside the cabinet 1 and outside the inner liner 3. The bottom of the conveying assembly is connected to a conveying pipe 4. The conveying assembly includes a conveying cover 9, which is L-shaped and installed outside the inner liner 3 but inside the cabinet 1. The two ends of the conveying cover 9 are respectively designated as an air inlet and an air outlet. One side of the inner liner 3 has an air duct 10 that communicates with the interior of the shell 5. One end of the conveying cover 9 is connected to the air duct 10 through the air inlet area. The other end of the conveying cover 9 is connected to the bottom of the exhaust hood 7 through the exhaust area. The top of the conveying pipe 4 is connected to the bottom of the conveying cover 9.

[0029] It is worth noting that after the refrigeration system inside the cabinet 1 generates cold air, the cold air enters the conveying hood 9 through the conveying pipe 4, and then enters the exhaust hood 7 through the conveying hood 9, and is discharged to the upper side of the inner liner 3 through the exhaust port 8.

[0030] The cold air cools one side and the top of the material, then flows through the top of the material into the inner liner 3 away from the exhaust port 8, and then moves downwards through the holes on the support grid 6 into the interior of the shell 5, thus completing the purpose of multi-directional cooling of the material.

[0031] Furthermore, the cold air inside the shell 5 re-enters the conveying hood 9 through the air duct 10, and then re-enters the exhaust hood 7 through the conveying hood 9, thereby achieving the circulation and cooling of the cold air. This fills the entire upper part of the inner liner 3 with cold air. Because the cold air has a high density, it will descend, thus creating air convection with the room temperature gas inside. The room temperature gas will float upward under the descending effect of the cold air. At this time, circulation is generated inside the cabinet 1. By changing the air duct, the cooling efficiency can be enhanced and energy loss can be reduced.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
