Description

Technical Field

[0001] This utility model relates to the field of refrigerators, and more specifically, to a multi-functional door for refrigerators. Background Technology

[0002] With the improvement of living standards, users have increasingly diversified requirements for refrigerators. Refrigerators not only need to meet customers' cooling needs but also require functions such as sterilization, disinfection, and preservation. Existing refrigerator deodorizers, such as those equipped with ozone generators, use ozone molecules produced by the generator to react with odor molecules inside the refrigerator to eliminate odors. However, simply adsorbing odor molecules with adsorbents has the disadvantage of a short deodorization lifespan; secondly, these generator devices generally produce ozone molecules by generating high voltage to decompose water molecules, resulting in complex structures and poor safety performance. Through long-term research, the inventors of this application have proposed a refrigerator door with a deodorizing function. Utility Model Content

[0003] To overcome the aforementioned shortcomings in the prior art, the purpose of this utility model is to provide a multi-functional door for refrigerators. This multi-functional door has a refrigerator deodorization function and the deodorizing catalyst can be replaced, ensuring that the refrigerator deodorization can be effectively used for a long time.

[0004] This utility model provides a multi-functional door for a refrigerator. The multi-functional door includes a door outer shell, a door inner shell, a knob assembly, and a refrigerator deodorizer. The door inner shell is fixed to the inner liner of the refrigerator door via the knob assembly. The refrigerator deodorizer is installed on the door inner shell. The door outer shell and the door inner shell are detachably connected and used to fix the refrigerator deodorizer. The door inner shell has a vent hole that communicates with the refrigerator deodorizer and is used to communicate with the refrigerator's refrigerator compartment or freezer compartment, so that the refrigerator deodorizer can deodorize the gas inside the refrigerator's refrigerator compartment or freezer compartment.

[0005] Furthermore, in an optional embodiment, the refrigerator deodorizer includes a deodorizer body and a deodorizer catalyst. The deodorizer body is provided with a plurality of vent holes, which are connected to the ventilation holes. The deodorizer catalyst is disposed inside the deodorizer body.

[0006] Furthermore, in an optional embodiment, the vent includes an air inlet and an air outlet, and the plurality of vents are respectively connected to the air inlet and the air outlet, so that the gas in the refrigerator compartment or freezer compartment enters the deodorizer body through the air inlet and is treated by the deodorizer catalyst, and then is discharged to the refrigerator compartment or freezer compartment through the air outlet.

[0007] Furthermore, in an optional embodiment, the inner shell of the door is provided with a mounting portion, the refrigerator deodorizer is mounted on the mounting portion, and both the air inlet and the air outlet are adjacent to the mounting portion.

[0008] Furthermore, in an optional embodiment, the air inlet includes two sets, and the two sets of air inlets are respectively located on both sides of the mounting portion; the air outlet is opposite to the mounting portion.

[0009] Furthermore, in an optional embodiment, the mounting portion is located in the middle of the inner shell of the door and is opposite to the knob assembly.

[0010] Furthermore, in an optional embodiment, the mounting portion snaps into the deodorizer body.

[0025] It should be noted that existing refrigerator deodorizers 140 are typically equipped with ozone generators. The ozone molecules generated by the generator react with odor molecules inside the refrigerator to remove odors. However, ozone generators generally produce ozone molecules by generating high voltage to decompose water molecules, resulting in complex structures and relatively poor safety performance. The inventors of this application, through long-term experience in refrigerator design and manufacturing, especially in extensive and in-depth research on refrigerator deodorization, have proposed the multi-functional refrigerator door 100 of this application, aiming to provide a deodorization device with a simple structure and high safety.

The door inner shell 120 is fixed to the inner liner of the refrigerator door via the knob assembly 130. The refrigerator deodorizer 140 is installed on the door inner shell 120. The door outer shell 110 and the door inner shell 120 are detachably connected and used to fix the refrigerator deodorizer 140. The door inner shell 120 is provided with a vent hole 121, which communicates with the refrigerator deodorizer 140 and is used to communicate with the refrigerator compartment or freezer compartment of the refrigerator, so that the refrigerator deodorizer 140 deodorizes the gas in the refrigerator compartment or freezer compartment of the refrigerator.

[0027] It should be noted that, in this embodiment of the invention, the inner shell 120 of the door is fixed to the inner liner of the refrigerator door, and the outer shell 110 of the door is detachably connected to the inner shell 120 via a knob assembly 130, so that the outer shell 110 can be removed from the inner shell 120. The refrigerator deodorizer 140 is installed in the inner shell 120 of the door, and when the inner shell 120 of the door is connected to the outer shell 110 of the door, the outer shell 110 of the door can fix the refrigerator deodorizer 140. At the same time, in order to facilitate the airflow inside the refrigerator, that is, the airflow deodorization in the freezer or refrigerator compartment, the inner shell 120 of the door is provided with a vent 121 in this embodiment of the invention. The air in the freezer or refrigerator compartment can enter the refrigerator deodorizer 140 through the vent 121, and after being purified and deodorized by the refrigerator deodorizer 140, it returns to the freezer or refrigerator compartment through the vent 121. This process can be achieved by utilizing the air circulation inside the refrigerator. The outer shell 110 of the door serves two purposes: firstly, it secures the refrigerator deodorizer 140; secondly, it conceals the deodorizer, thus enhancing the refrigerator's appearance. The multi-functional refrigerator door 100 provided in this embodiment features a simple structure, attractive appearance, and flexible installation. It occupies little space and fully utilizes the circulation of gas within the refrigerator to achieve deodorization. Furthermore, the deodorizing catalyst can be replaced, ensuring long-term effective deodorization.
