Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0025] like Figures 1-6 As shown, this utility model provides a glass door decondensation mechanism, which is applied in refrigeration equipment such as freezers and display cases. The refrigeration equipment includes a cabinet body 1 and a glass door 2. The cabinet body 1 has an internal chamber, and the glass door 2 is hinged to one side of the cabinet body 1 for opening or closing the internal chamber. The glass door decondensation mechanism includes a compressor chamber 3. A compressor 8 and a condenser 9 are arranged at the rear of the compressor chamber 3. An air inlet is arranged at the rear end of the compressor chamber 3. A cross-flow fan 4 is arranged at the front end of the compressor chamber 3. A front cover 34 located at the bottom of the glass door 2 is arranged at the front end of the compressor chamber 3. A guide air duct is arranged in the front cover 34. An air outlet 341 is arranged at the upper end of the front cover 34. The air blown by the cross-flow fan 4 is blown onto the surface of the glass door 2 through the guide air duct.

[0026] For details, please refer to Figure 2The press chamber 3 is located at the bottom of the cabinet 1 and consists of an upper chamber plate 31, a lower chamber plate 32, a side chamber plate 33, a front cover 34, and a rear cover 35, which are fixedly connected by bolts. The upper chamber plate 31 is located at the top of the press chamber 3, the lower chamber plate 32 is located at the bottom of the press chamber 3, the side chamber plates 33 are located on both sides of the press chamber 3, and the rear cover 35 is located at the rear end of the press chamber 3. The rear cover 35 has a grille structure and serves as the air inlet of the press chamber 3. The front cover 34 is located at the front end of the press chamber 3, and the glass door 2 is located above the front cover 34. An air outlet 341 is located on the top of the front cover 34. The compressor compartment 3 is equipped with a compressor 8 and a condenser 9 at the rear. As part of the refrigeration system, the compressor 8 and the condenser 9 release a large amount of heat through the compression of the compressor 8 and the condensation of the condenser 9, which heats the temperature of the air flowing through the compressor 8 and the condenser 9. A condenser fan 91 is provided on one side of the condenser 9 to improve the heat exchange rate between the compressor 8 and the condenser 9.

[0027] refer to Figure 2 Air drawn into the compressor chamber 3 flows sequentially through the compressor 8, condenser 9, and cross-flow fan 4, and is blown onto the glass door surface from the air outlet 341. The cross-flow fan 4 is located at the front of the compressor chamber 3 and is fixedly installed in the fan mounting bracket 5. The fan mounting bracket 5 includes a front plate 51, a rear plate 52, and a base plate 53. (See reference...) Figure 4 In the shaded area, the left and right sides of the rear panel 52 are respectively spaced from the side compartment panels 33 on both sides. The rear panel 52, together with the side compartment panels 33, the lower compartment panel 32 and the upper compartment panel 31, form the first air inlet 54 and the second air inlet 55.

[0028] The cross-flow fan 4 is fixedly installed on the base plate 53 by bolts. The upper part of the cross-flow fan 4 is the air inlet side, and the front part is the air outlet side. The front plate 51 is provided with an air outlet 56 that matches the air outlet side of the cross-flow fan 4. The air in the compressor chamber 3 is drawn into the cross-flow fan 4 from the air inlet side of the upper part of the cross-flow fan 4 through the first air inlet 54 and the second air inlet 55. After being accelerated by the fan blades of the cross-flow fan 4, it is ejected from the air outlet side.

[0029] The fan mounting bracket 5 is fixedly installed in the compressor chamber 3 using a top and side fixing structure. An upper fixing bracket 6, L-shaped, is located at the bottom of the upper chamber plate 31. One side of the upper fixing bracket 6 is bolted to the upper chamber plate 31, and the other side is bolted to the rear plate 52. A side fixing bracket 7, also L-shaped, is located on the inner side of one side chamber plate 33. One side of the side fixing bracket 7 is bolted to the side chamber plate 33, and the other side is bolted to the front plate 51. The fan mounting bracket 5 and the compressor chamber 3 are thus fixedly connected via the upper fixing bracket 6 and the side fixing bracket 7.

[0030] A front cover 34 is provided at the air outlet of the front panel 51. A cavity is provided inside the front cover 34, and an air outlet 341 is provided at the top of the front cover 34 to guide the airflow. An upper guide plate 343 and a lower guide plate 342 are respectively provided on the upper and lower sides of the cavity. The upper guide plate 343 is positioned above the air outlet 56 and is fixed to the front side of the front panel 51 with bolts. The lower guide plate 342 faces the air outlet 56 and is located at the corner of the front cover 34, and is fixedly connected to the front cover 34 with bolts. The upper guide plate 343 and the lower guide plate 342 form a guiding air duct. The horizontal airflow blown by the cross-flow fan 4 is redirected to a vertical direction through the guiding air duct and blown onto the surface of the glass door 2.

[0031] The air drawn into the compressor chamber 3 is first heated by the compressor 8 and condenser 9, and then blown to the surface of the glass door 2 by the cross-flow fan 4. This accelerates the air convection on the surface of the glass door 2, preventing water vapor in the air from condensing on the surface of the glass door 2. At the same time, the hot air accelerates the evaporation of condensation on the surface of the glass door 2, ensuring the decondensation effect on the surface of the glass door 2.

[0032] refer to Figure 3 A cross-flow fan 4 is installed at the front of the compressor chamber 3, reducing the space occupied by the compressor chamber 3. Compared with the prior art, the space at the front of the compressor chamber 3 is only half that at the rear. (Reference) Figure 1 An additional half-layer chamber can be added to the front of cabinet 1, which effectively improves the space utilization of cabinet 1.

[0033] When installing the cross-flow fan 4 and the front cover 34, firstly, fix the cross-flow fan 4 in the fan mounting bracket 5, then fix the assembled fan mounting bracket 5 to the upper mounting bracket 6 and the side mounting bracket 7, then install the upper guide plate 343 on the front side of the front plate 51 and the lower guide plate 342 in the front cover 34, and finally fix the front cover 34 to the front end of the compressor chamber 3 to complete the assembly of the cross-flow fan 4 and the front cover 34. The cross-flow fan 4 is assembled firmly and is easy to install.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
