Detailed Implementation

[0021] 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.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a freezer door assembly, including a freezer door body 100, the freezer door body 100 including a main door 101, a sealing magnetic strip 102 provided at the inner surface edge of the main door 101, and a protruding plate 103 provided at the inner middle position of the main door 101. When closing the main door 101, the freezer door body 100 is directly sealed and closed by the magnet on the edge of the freezer door frame attracted by the sealing magnetic strip 102, thus protecting the surface of the freezer. The freezer door body 100 is also provided with:

[0023] The buffer protection mechanism includes a limiting buffer assembly disposed on the inner surface of the protruding plate 103 and inside the main cabinet door 101. Sliding control components are equidistantly disposed at both ends of the limiting buffer assembly. A sealing assembly is disposed at the connection between the edge of the protruding plate 103 and the surface of the main cabinet door 101. When the freezer door body 100 is installed in the freezer and is closed, it is protected by the buffer protection mechanism when it is subjected to hard frozen items in the protruding part inside. This prevents the protruding plate 103 from being deformed and damaged by impact, thus improving the buffer protection effect of the freezer door body 100 when it is installed in the freezer.

[0024] In order to facilitate the cushioning protection of the protruding plate 103 when it is impacted by the limiting buffer assembly, in this embodiment, preferably, the limiting buffer assembly includes a limiting buffer groove 1012 opened in the middle position inside the main cabinet door 101. The lower surface of the protruding plate 103 is embedded in the limiting buffer groove 1012. Several buffer springs 1013 are provided at the connection between the lower surface of the protruding plate 103 and the interior of the limiting buffer groove 1012. When the buffer springs 1013 are deformed under force, they can provide elastic cushioning protection for the protruding plate 103. Both sides of the protruding plate 103 are integrally formed with limiting side plates 1014. When the protruding plate 103 is elastically cushioned, the limiting side plates 1014 limit the protruding plate 103 inside the limiting buffer groove 1012 for cushioning protection.

[0025] In order to facilitate the stable buffering of the protruding plate 103 by means of the sliding control component, in this embodiment, preferably, the sliding control component includes control grooves 1016 formed on both sides of the protruding plate 103, and a control rod 1015 sliding inside the control groove 1016. The bottom end of the control rod 1015 is fixed to the bottom end of the limiting buffer groove 1012 by screws. When the protruding plate 103 is buffered, it drives the control rod 1015 to slide inside the control groove 1016, so that the protruding plate 103 is stably buffered and protected.

[0026] In order to facilitate the sealing connection between the edge of the protruding plate 103 and the interior of the limiting buffer groove 1012 through the sealing assembly, and to prevent dirty water from entering the interior, in this embodiment, preferably, the sealing assembly includes a flexible sealing strip 1011 that is snapped onto the connection between the edge of the protruding plate 103 and the surface of the main cabinet door 101, and the cross-section of the flexible sealing strip 1011 is arc-shaped. When the protruding plate 103 is buffered inside the limiting buffer groove 1012, the edge of the limiting buffer groove 1012 is sealed by the flexible sealing strip 1011.

[0027] The cleaning mechanism includes a cleaning component disposed on the surface of the raised plate 103. A sliding component is provided at the connection between the end of the cleaning component and the side of the raised plate 103. When the freezer door body 100 is installed in the freezer, the cleaning mechanism slides and cleans the surface of the raised plate 103 when dirty water and dirt are generated on the surface of the raised plate 103. The sliding cleaning process is convenient and improves the convenience of cleaning the inner surface of the raised plate 103 when the freezer door body 100 is installed in the freezer.

[0028] In order to facilitate the sliding cleaning of dirt adhering to the surface of the raised plate 103 by the cleaning component, and to make the cleaning process convenient, in this embodiment, preferably, the cleaning component includes a movable frame 1031 disposed at the bottom end of the front surface of the raised plate 103. The inner surface of the movable frame 1031 is provided with a rubber scraper 1032. The inner surface of the rubber scraper 1032 contacts the surface of the raised plate 103, so that the movable frame 1031 and the rubber scraper 1032 can slide on the surface of the raised plate 103 to clean the dirt. The cleaning process is convenient, and it is not easy to scratch when using matching cleaning tools.

[0029] In order to facilitate the sliding cleaning of the movable frame 1031 and the rubber scraper 1032 by means of the sliding assembly, in this embodiment, preferably, the sliding assembly includes sliding grooves 1033 formed on both sides of the protruding plate 103, and a sliding block 1034 sliding inside the sliding groove 1033. The end of the sliding block 1034 is fixed to the end of the movable frame 1031 by screws. The sliding block 1034 is slid inside the sliding groove 1033 to drive the movable frame 1031 and the rubber scraper 1032 to slide and clean on the surface of the protruding plate 103.

[0030] The working principle and usage process of this utility model: When using this type of freezer door assembly, the freezer door body 100 is directly installed on the surface of the freezer through the hinge. After the freezer door body 100 is installed, when closing the main door 101, it is directly attracted and closed by the magnet on the edge of the freezer door frame through the sealing magnetic strip 102, so that the freezer door body 100 can be sealed and closed on the surface of the freezer for protection.

[0031] Then, when the freezer door body 100 is closed on the surface of the freezer and subjected to a large force, and at the same time, a relatively hard frozen item protrudes from the surface of the freezer, the inner surface of the protruding plate 103 touches the surface of the hard item and is subjected to an impact force when the main door 101 is closed. The impact of the protruding plate 103 causes the buffer spring 1013 to be stressed. The buffer spring 1013 deforms under the stress and limits the protruding plate 103 inside the limiting buffer groove 1012 through the limiting side plate 1014 for buffering. During buffering, the control slide rod 1015 slides inside the control slide groove 1016 to control the movement. This makes it easy to provide stable buffering protection when the protruding plate 103 is impacted, and it is not easy for the protruding plate 103 to be deformed and damaged by impact. This improves the buffering protection effect of the freezer door body 100 when it is installed in the freezer.

[0032] Finally, when the freezer door body 100 is closed and the freezer is in use, if the inner surface of the raised plate 103 comes into contact with items and produces dirty water, or if the main door 101 is opened and the surface of the raised plate 103 is exposed to the outside and dirt falls in, the movable frame 1031 can be directly held and slid inside the sliding groove 1033 via the sliding block 1034. The movable frame 1031 drives the rubber scraper 1032 to slide on the surface of the raised plate 103, so that the rubber scraper 1032 slides on the surface of the raised plate 103 to clean the surface of the raised plate 103 until the dirt after sliding and cleaning falls to the bottom of the raised plate 103 into the trash can placed at the bottom. The cleaning process is convenient and does not require the use of external cleaning tools, making it less likely that the matching cleaning tools will scratch or damage the raised plate 103, thus improving the convenience of cleaning the inner surface of the raised plate 103 when the freezer door body 100 is installed on the freezer.

[0033] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
