Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators and provides a wind shielding device for a refrigerator. Background Art

[0002] The air intake of the condenser of the vertical freezer is generally through the front cover of the cabin. After the air passes through the condenser, it diffuses to the surroundings. Some hot air will be attracted by the fan again due to the attraction of the fan to dissipate the heat of the condenser, causing the hot air of the system to be unable to be discharged, and the heat dissipation efficiency of the system is low. For some products, the cabin is an integrated welded structure, and adding a windshield structure on the condenser side will increase the difficulty of the production process; for some products, the cabin is an assembled structure, but due to structural limitations, the windshield structure is difficult to install.

[0021] The following will clearly and completely describe the technical solution of the utility model in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0022] In the prior art, the condenser 2 is usually placed at the edge of the cabin 1, and the high-temperature refrigerant in the condenser 2 exchanges heat with the outside air to reduce the temperature of the refrigerant. Since the hot air generated by the condenser 2 will spread to the surroundings, part of the hot air will be sucked back into the condenser 2 by the suction of the fan, reducing the heat dissipation efficiency of the entire system. In order to improve the heat dissipation efficiency, the utility model provides a refrigerator wind shielding device, which surrounds the air inlet side of the condenser 2, including the cabin 1, the front cover 3 and the air duct assembly 4, one side of the cabin 1 is the air inlet side, and the other side is the air outlet side. Side panels are arranged on the other two sides of the cabin 1, and a bottom plate is arranged at the bottom of the cabin 1. The condenser 2 is arranged at the edge of the air inlet side of the cabin 1, and the condenser 2 is fixedly mounted on the bottom plate of the cabin 1.

[0023] A front cover 3 is provided on the air inlet side of the nacelle 1, and connecting plates are provided on both sides of the front cover 3 and the bottom of the front cover 3. The front cover 3 is fixed to the side wall of the nacelle 1 by bolts. The front cover 3 is provided with an air inlet 31 at a position corresponding to the condenser 2, and a dustproof plate 32 is installed in the air inlet 31.

[0024] An air duct assembly 4 is provided in the front cover 3, and the air duct assembly 4 surrounds the air inlet 31 and the outside of the condenser 2, so that the air outlet side of the condenser 2 forms a chamber with the cabin 1, the front cover 3 and the air duct assembly 4, and the hot air is blocked in the cabin 1. The hot air can only leave from the air outlet side at the rear of the cabin 1, avoiding the hot air from re-entering the cabin 1 from the air inlet side of the condenser 2, thereby solving the problem of heat exchange and return air of the condenser 2.

[0025] Specifically, the windshield assembly can be an integrated structure, with a square channel arranged around the air inlet 31, and installed on the side wall of the cabin 1, or a split structure. To facilitate the assembly of the windshield assembly, it is preferred to use a split structure, including an upper baffle 41 and a U-shaped plate 42, with the top of the U-shaped plate 42 abutting against the bottom of the upper baffle 41. A connecting piece is arranged on the top of the upper baffle 41, which is fixedly installed on the upper side of the cabin 1 by bolts, and a connecting piece is arranged on the bottom of the U-shaped plate 42, which is fixedly installed on the lower side of the cabin 1 by bolts. An adhesive portion is arranged on the top of the U-shaped plate 42, and a sponge adhesive strip is arranged on the adhesive portion, and the relative position of the U-shaped plate 42 and the upper baffle 41 is fixed by the sponge adhesive strip. The side plate of the U-shaped plate 42 abuts against the air inlet 31 of the front cover 3 and the side wall of the condenser 2 to ensure the sealing effect. A connecting piece is provided at the bottom of the U-shaped plate 42 and is fixed to the side wall of the cabin 1 by bolts. A supporting plate 33 is provided on the inner side of the air inlet 31 of the front cover 3 and abuts against the bottom of the upper baffle 41 .

[0026] The above-mentioned wind shielding structure is not only applicable to a single condenser 2, but also applicable to multiple condensers 2. When the above-mentioned structure is used for multiple condensers 2, since there are gaps between the condensers 2, hot air may diffuse from the gaps between the condensers 2 to the air inlet side of the condenser 2. Therefore, when there are multiple condensers 2, an air duct baffle 5 is arranged between the condensers 2. The air duct baffle 5 is U-shaped, and its height matches the height of the condenser 2, and its width matches the spacing distance between the condensers 2. Sealing strips are respectively pasted on both sides of the air duct baffle 5, and it is inserted between the condensers 2 to isolate the diffusion of hot air.

[0027] The present invention adds an additional duct assembly 4 on the air inlet side of the cabin 1. The duct assembly 4 cooperates with the front cover 3 of the cabin 1 to surround the condenser 2 and isolate the hot air in the cabin 1, so as to prevent the hot air from re-entering the cabin 1 from the air inlet side of the condenser 2. During installation, the upper baffle 41 and the U-shaped plate 42 of the duct assembly 4 are first installed on the side wall of the cabin 1 respectively, and the upper baffle 41 and the U-shaped plate 42 are fixed with sponge strips, and then the front cover 3 is fixed to the side wall of the cabin 1 by bolts and installed on the outside of the duct assembly 4. When the refrigerator is provided with multiple sets of condensers 2, the duct baffle 5 with sealing strips is plugged between the condensers 2, which is suitable for refrigerators with different refrigeration systems. The windshield device has a simple structure, effectively solves the problem of heat exchange and return air of the condenser 2, improves the heat exchange efficiency, and the installation process of the duct assembly 4 and the duct baffle 5 is simple and easy to operate.

[0028] The above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the invention of the utility model.
