Description

Technical Field

[0001] The present invention relates to the technical field of household refrigerators, and in particular to a fresh air refrigerator. Background Art

[0002] In today's home appliance market, air-cooled refrigerators have been widely recognized and used for their efficient refrigeration and frost-free characteristics. The core working principle of air-cooled refrigerators mainly relies on their built-in fans and air duct systems. These components work together to evenly distribute cold air throughout the refrigerator compartment, effectively solving the frost problem that is prone to occur in traditional direct-cooling refrigerators. This technological innovation not only improves the refrigeration efficiency of refrigerators, but also greatly facilitates users' daily use and maintenance.

[0003] However, despite the remarkable success of air-cooled refrigerators in the market, there are still some problems to be solved in the existing air duct structure design. At present, most air-cooled refrigerators adopt a fixed air duct structure, which usually sets air inlets and outlets on the back wall of the refrigerator compartment. The fan blows the cold air generated by the evaporator into the refrigerator compartment, and forms a circulating airflow through a specific air duct to achieve a uniform cooling effect. However, in actual applications, this fixed air duct design is often difficult to ensure the perfect distribution of cold air in the refrigerator compartment. Especially in some special areas, such as inside the drawer and near the door body, due to the limitation of the air flow path and the influence of obstacles, uneven temperature distribution often occurs. These temperature dead spots not only affect the preservation effect of food, but may also cause users to question the overall refrigeration performance of the refrigerator.

[0004] In addition, the existing air duct systems are often complex in design, which not only increases the difficulty and cost of production, but may also have an adverse effect on the energy consumption of the refrigerator. Due to the obstruction of the flow of cold air in the air duct, the compressor needs to be started and operated more frequently to maintain the set temperature in the refrigerator. This frequent start-up not only increases the energy consumption of the refrigerator, but may also damage the service life of the compressor. At the same time, although air-cooled refrigerators are sold with a frost-free function, in actual use, due to the unevenness of the cold air circulation, some areas may still be partially frosted, which not only affects the aesthetics of the refrigerator, but may also have a certain negative impact on the refrigeration effect.

[0049] The fresh air refrigerator also includes:

The fresh air components in conventional fresh air refrigerators can only perform air purification, but in the present embodiment, it is necessary to consider the coordination with the air duct component 300, so it is necessary to add the refrigeration function to the fresh air component 400. Through such a structural design, the return air, refrigeration and air supply can be carried out in the same pipeline passage, so that the structure of the air duct component 300 can be simplified and the complex design of multiple pipelines can be avoided.

[0056] Among them, see Figure 2 It can be seen that the air supply assembly 310 and the return air assembly 320 are arranged on a side of the refrigeration compartment away from the door body 200, and the specific positions should be two angle areas formed by the three side walls of the refrigeration compartment, and only the air outlets of the air supply assembly 310 and the return air assembly 320 are located in the refrigeration compartment, which can further reduce the required space for the air duct.

[0057] Further, in some embodiments, the fresh air component 400 is connected to the air supply component 310 and the return air component 320 respectively;

[0058] The fresh air component 400 is configured as follows:

[0059] Purifying the air recovered by the return air assembly 320;

[0060] The recovered air is purified and cooled in sequence, and the treated air is delivered to the refrigeration room through the air supply assembly 310 .

[0061] Specifically, in this embodiment, the fresh air component 400 completes air supply and return through the air supply component 310 and the return air component 320 respectively; when the return air enters the fresh air component 400 through the return air component 320, the fresh air component 400 purifies and cools the return air, and transports the treated air along the inner wall of the refrigeration compartment to the refrigeration compartment through the air supply component 310.

[0065] A plurality of side wall air supply ports 313 are evenly arranged on the side of the air supply component 310 .

[0066] Specifically, in the present embodiment, considering that the size and position of the air outlet will also affect the cooling effect, in the present embodiment, the top air outlet 311 is arranged at the top of the air supply assembly 310, the bottom air outlet 312 is arranged at the bottom of the air supply assembly 310, and a plurality of side wall air outlets 313 are arranged on the side of the air supply assembly 310; the top area, the bottom area, the dead corner of the top area and the dead corner of the bottom area of ​​the refrigeration chamber are uniformly cooled through the top air outlet 311 and the bottom air outlet 312; the low-temperature air is uniformly and accurately transported from the inner wall of the refrigeration chamber to the refrigeration chamber from multiple air supply points through a plurality of side wall air outlets 313, so that the distribution of the low-temperature air in the refrigeration chamber is always in a uniform and full state, and the problem of reduced refrigeration utilization rate due to excessively large air outlets can be avoided.

[0070] A plurality of side wall return air vents 323 are evenly arranged on the side of the air supply assembly 310 .

[0071] Specifically, in the present embodiment, although the air supply assembly 310 is provided with air supply outlets at the top, bottom and side walls, there is still a certain problem of uneven cooling for the dead corners on the return air side. Therefore, the top return air outlet 321, the bottom return air outlet 322 and the side wall return air outlet 323 corresponding to the air supply outlet in the air supply assembly 310 need to be provided in the return air assembly 320, so that any position in the refrigeration room can be effectively and evenly cooled.

[0072] Furthermore, in some embodiments, the air duct assembly 300 further includes:

[0073] The air outlet inner guide grille 330 is arranged on a side of the refrigeration compartment outside and away from the door body 200. The air outlet inner guide grille 330 has a plurality of air inlets and a plurality of air outlets. All the air inlets of the air outlet inner guide grille 330 are connected to the fresh air assembly 400. The air outlets of the air outlet inner guide grille 330 are respectively connected to the top air supply port 311, the bottom air supply port 312 and the side wall air supply port 313.

[0075] Specifically, in the present embodiment, the low-temperature air produced by the fresh air component 400 is independently delivered to the refrigeration compartment through the top air supply port 311, the bottom air supply port 312 and the side wall air supply port 313 through the air outlet inner guide grille 330, thereby not only realizing independent air supply but also improving the utilization rate of refrigeration, avoiding the problem that the refrigeration function is set in the fresh air component 400 and the fresh air component 400 is generally small in size, making it impossible to set a high-power refrigeration equipment; similarly, setting the return air inner guide grille 340 can also play a role in improving the refrigeration effect.

[0076] Figure 3 This is an enlarged schematic diagram of a fresh air component in a fresh air refrigerator according to the present application.

[0081] The evaporator module 420 needs to be arranged after the purification module 410, that is, the purification process must be performed before the cooling process, so as to avoid the impurities in the refrigeration compartment from contaminating the evaporator module 420 to a certain extent.

[0082] Furthermore, in some embodiments, the purification module 410 includes:

[0083] An ultraviolet germicidal lamp 411, wherein the ultraviolet germicidal lamp 411 is configured to sterilize the air recovered by the return air assembly 320;

[0084] The deodorizer 412 is configured to purify the air that has completed the sterilization treatment.

[0085] Specifically, in this embodiment, considering that food and other substances with a certain odor are often stored in the refrigerator, it is necessary to perform sterilization and odor removal processes at the same time to achieve the fresh air effect.

[0086] Furthermore, in some embodiments, the fresh air component 400 further includes:

[0087] The fan 430 and the evaporator module 420 are disposed between the fan 430 and the deodorizer 412 . The fan 430 is configured to transport the air processed by the evaporator module 420 to the refrigeration compartment.

[0089] This embodiment has the following advantages:

[0090] By changing the air duct structure, the heat exchange efficiency of the air-cooled refrigerator is higher during the operation of the refrigeration program.
