Description

Technical Field

[0001] The utility model relates to the technical field of air curtain refrigerators, in particular to a refrigerator with an anti-condensation air curtain structure. Background Art

[0002] Air curtain freezer is a special refrigeration equipment, which is characterized by the built-in circulating air refrigeration technology to blow out cold air evenly, forming a cold air curtain, thereby effectively isolating the outside hot air from entering the interior of the freezer and maintaining a stable and uniform temperature inside the cabinet. This equipment is widely used in supermarkets, convenience stores and other commercial places, mainly for refrigerating beverages, yogurt, milk, vacuum-packed meat, cooked food, fruits and other commodities. At present, the anti-condensation air curtain structure of the air curtain freezer generally adopts an electrically heated window to automatically prevent condensation during use.

[0003] In the existing air curtain freezer, the air outlet plate at the rear end of the shelf is generally fixed. When the height of the shelf is adjusted, the distance between the air outlet position at the upper end of the rear air outlet plate and the shelf will change, and it is inconvenient to ensure the air cooling effect after the shelf in the air curtain freezer is adjusted. Therefore, we propose a freezer with an anti-condensation air curtain structure. Utility Model Content

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] Embodiment 1:

[0026] like Figure 1-5 As shown, the present embodiment provides a refrigerator with an anti-condensation air curtain structure, including a refrigerator body 100, a blocking component 200 and an adjusting component 300, the refrigerator body 100 includes a cabinet door 101 movably installed at its front end, and an electric heating window 102 installed in the cabinet door 101, the blocking component 200 includes a rear air outlet plate 201 arranged at the rear end of the refrigerator body 100, and a plurality of groups of air outlets 202 arranged and opened in the rear air outlet plate 201, a plurality of groups of racks 203 are also movably arranged and installed in the refrigerator body 100 at the front end of the rear air outlet plate 201, and a plurality of groups of ventilation holes 203 are also arranged and opened in the rear side of the racks 203. The vents 204 on the rack 203 are aligned with the air outlet 202 on the rear air outlet plate 201. The sealing assembly 200 further comprises a binding hole 208 which is penetrated through the sealing plate 206 at the bottom of the spring 207, and a binding column 209 which is fixedly installed on the rack 203 above the binding hole 208, and the binding column 209 is movably installed in the binding hole 208.

[0027] Specifically, the air curtain freezer is a special refrigeration equipment, which is characterized by using the built-in circulating air refrigeration technology to evenly blow out cold air to form a cold air curtain, thereby effectively isolating the outside hot air from entering the refrigerator and maintaining the temperature inside the cabinet stable and uniform. At present, the anti-condensation air curtain structure of the air curtain freezer generally adopts the installation of an electric heating window 102 to automatically prevent condensation during use. The blocking plate 206 at the rear end of the shelf 203 in the refrigerator body 100 is movably installed by a spring 207, and the outlet 202 on the rear air outlet plate 201 after the rear end is adjusted can be automatically blocked when the height of the shelf 203 is freely adjusted, so that when the height of the shelf 203 is adjusted, the air outlet 202 on the rear air outlet plate 201 is automatically blocked. The vent 204 at the bottom is always aligned with the air outlet 202 at the rear end and the opening size is uniform, thereby ensuring the air cooling effect on the items on the upper end of the shelf 203 after the shelf 203 is adjusted. In addition, the multiple sets of shelves 203 with flexible height adjustments in the refrigerator body 100 can also improve the convenience and applicability of placing items during use. The blocking plate 206 fixedly connected to the rear end of the shelf 203 by a spring 207 is mainly used for automatically blocking the bottom under the elastic force of the spring 207 after the bottom shelf 203 moves downward. The restraining column 209 restrained and installed in the blocking plate 206 is mainly used for restraining the position of the blocking plate 206 during movement and adjustment.

[0028] Embodiment 2:

[0029] Based on the first embodiment, Figure 3-4 As shown, the adjustment component 300 includes notches 301 arranged on both sides of the storage rack 203, and fixing strips 302 fixedly installed on both sides of the inner wall of the refrigerator body 100, and multiple groups of sockets 303 are arranged in the fixing strips 302. The adjustment component 300 also includes fixing ears 304 fixedly installed on both sides of the side walls of the storage rack 203, and threaded holes 305 opened in the fixing ears 304. Screws 306 are also movably installed in the threaded holes 305 on one side of the fixing ears 304 and the sockets 303.

[0030] Specifically, the fixing bars 302 fixedly installed on both sides of the side walls of the refrigerator body 100 can also ensure that the rack 203 is subjected to balanced force during use after being installed through the fixing ears 304, thereby ensuring its stability during use and preventing it from being damaged easily during vibration and shaking.

[0031] The working principle and use process of this utility model:

[0032] When adjusting the height of the storage rack 203 at the top of the refrigerator body 100, the screws 306 of the fixing ears 304 at the bottom of the top shelf 203 are first loosened in sequence so that the screws 306 are moved out of the insertion holes 303 in the fixing strips 302. After both ends of the top shelf 203 are freed from the constraints, the top shelf 203 can be moved up and down to compress or rebound the blocking plate 206 at the bottom of the top shelf 203, so that the bottom space of the top shelf 203 after the top shelf 203 moves up and down is automatically blocked by the blocking plate 206. After the position adjustment of the top shelf 203 is completed, the screws 306 in the fixing ears 304 are screwed into the corresponding insertion holes 303 in the fixing strips 302 again to complete the fixation of the adjusted top shelf 203. After the top shelf 203 is adjusted, the vent 204 at its upper end will remain aligned with the rear end air outlet 202 and the size before and after adjustment will be the same.

[0033] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
