DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In the following text, only some exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present utility model. Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0027] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0028] As Figures 1 - 4 shown, an embodiment of the present utility model provides an additional air duct for eliminating condensation inside the cabinet, including a defogging assembly 1. The defogging assembly 1 includes a cabinet body 11, a bottom plate 12, a refrigeration chamber 13, an evaporator 14, an evaporation fan 15, a return air port 16, an L-shaped inner lining plate 17, a main air duct 18, a lamp shade 19, a wind guiding plate 20, a first air duct 21, and a second air duct 22.

[0029] On both lower sides of the inner side wall of the cabinet body 11, a bottom plate 12 is fixedly connected. Between the lower surface of the bottom plate 12 and the inner bottom wall of the cabinet body 11, a refrigeration chamber 13 is provided. At the rear of the inner side wall of the refrigeration chamber 13, an evaporator 14 is installed. At the front of the inner side wall of the refrigeration chamber 13 near the evaporator 14, an evaporation fan 15 is provided. At the front of the inner side wall of the refrigeration chamber 13, a return air port 16 is provided. On both rear sides of the inner side wall of the cabinet body 11 near the bottom plate 12, an L-shaped inner lining plate 17 is fixedly connected. Between the outer side wall of the L-shaped inner lining plate 17 and the inner side wall of the cabinet body 11, a main air duct 18 is provided. The air inlet of the main air duct 18 is communicated with the air outlet of the refrigeration chamber 13. At the front of both upper sides of the inner side wall of the cabinet body 11 near the L-shaped inner lining plate 17, a lamp shade 19 is fixedly connected. At the top of the rear surface of the lamp shade 19, a wind guiding plate 20 is fixedly connected. Between the lower surface of the wind guiding plate 20 and the upper surface of the L-shaped inner lining plate 17, a first air duct 21 is provided. Between the upper surface of the wind guiding plate 20 and the inner top wall of the cabinet body 11, a second air duct 22 is provided. The cold air blown out from the air outlet of the main air duct 18 is separated into two parts by the wind guiding plate 20, so that a part of the cold air enters the first air duct 21, and the other part of the cold air enters the second air duct 22.

[0030] In one embodiment, specifically: at the bottom of the rear surface of the lamp shade 19, a honeycomb plate 23 is fixedly connected. The rear surface of the honeycomb plate 23 is fixedly connected to the top of the front surface of the L-shaped inner lining plate 17. The cold air blown out from the first air duct 21 is guided by the honeycomb plate 23, so that the cold air evenly blows towards the goods on the shelf layer board 27.

[0031] In one embodiment, specifically: on the inner side wall of the return air port 16, a baffle 24 is fixedly connected. On the upper surface of the baffle 24, a plurality of return air holes 25 are opened. Through the return air holes 25 on the baffle 24, it is convenient for air to circulate into the refrigeration chamber 13. At the same time, the baffle 24 can also effectively prevent objects from falling into the interior of the refrigeration chamber 13, protecting the integrity and safety of the internal structure of the system.

[0032] In one embodiment, specifically: glass doors 26 are hinged to the front portions on both sides of the inner sidewall of the cabinet body 11. The air outlet of the second air duct 22 is located at the top of the rear surface of the glass door 26. By having the air outlet of the second air duct 22 located at the top of the rear surface of the glass door 26, it is convenient for the cold air blown out by the second air duct 22 to flow downward along the glass door 26, thereby preventing fogging and condensation on the surface of the glass door 26.

[0033] In one embodiment, specifically: a plurality of shelf laminates 27 are fixedly connected to the front portions near the L-shaped inner lining plate 17 in the middle of both sides of the inner sidewall of the cabinet body 11. The shelf laminates 27 facilitate placing goods.

[0034] In one embodiment, specifically: handles 28 are fixedly connected to the middle portions on the side where the front surfaces of the two glass doors 26 are close to each other. The handles 28 facilitate pulling the glass doors 26 to open.

[0035] In one embodiment, specifically: an LED lamp tube 29 is provided on the inner sidewall of the lamp shade 19. The LED lamp tube 29 in the lamp shade 19 facilitates illuminating the interior of the cabinet body 11.

[0036] In one embodiment, specifically: support seats 30 are fixedly connected to both sides and the middle of the lower surface of the cabinet body 11. Support feet 31 are fixedly connected to the front and rear portions of the lower surface of the support seats 30. By supporting the cabinet body 11 with the support feet 31 at the bottom of the support seats 30, the stability of the cabinet body 11 is increased.

[0037] When the utility model is working: when the system starts, the evaporation fan 15 starts to work, generating an air flow. The air is inhaled into the refrigeration chamber 13 through the air return opening 16. The evaporator 14 cools down the inhaled air, reducing its temperature and absorbing the moisture in the air. The cooled cold air enters the main air duct 18 and flows along the main air duct 18. When the cold air reaches the air outlet of the main air duct 18, it is separated into two parts by the air deflector 20. One part of the cold air enters the first air duct 21 and is blown out through the honeycomb panel 23, directly cooling the items on the shelf board 27, which helps to reduce the condensation on the surfaces of these items caused by the temperature difference. The other part of the cold air enters the second air duct 22 and is blown out from the gap between the glass door 26 and the lampshade 19. The cold air flows along the lampshade 19 and the glass door 26, which helps to keep the temperature near the glass door 26 and the lampshade 19 appropriate and reduce the condensation caused by the temperature difference. During the downward flow of the cold air in the first air duct 21 and the second air duct 22, it will gradually heat up and absorb the moisture in the surrounding environment. These air finally returns to the refrigeration chamber 13 through the air return holes 25 on the baffle 24 in the air return opening 16. The air returning to the refrigeration chamber 13 is cooled by the evaporator 14 again, thus completing a closed-loop air circulation system. The setting of the baffle 24 not only helps to optimize the air flow path and improve the cooling efficiency, but also can effectively prevent items from falling into the interior of the refrigeration chamber 13, protecting the integrity and safety of the internal structure of the system.

[0038] The above is only the specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art in the technical field disclosed by the utility model can easily think of various changes or substitutions within the technical scope disclosed by the utility model, and these should all be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claimed rights.
