Background
Refrigerators are a type of household appliances that are currently more common. The refrigerator can form a low temperature environment in its own storage chamber, thereby extending the preservation time of foods placed in the storage chamber. The freezing storage mode is mainly used for storing low-temperature articles and completely freezing the articles, so that the storage time of articles and foods is greatly prolonged.
In the prior art, an air duct of an existing refrigerator is arranged at the back of the refrigerator, and cold air is directly blown against articles in the refrigerating process of the refrigerator. Often, the food is frozen due to too low a wind temperature and the supercooled state of the food disappears as a result of direct blowing of the food, resulting in ice crystal formation and supercooled storage of the product. When the air-cooled refrigerator is used for defrosting, the temperature of the freezing chamber is rapidly increased, and the temperature between the freezing chamber and the defrosting is greatly floated due to supercooling and temperature rise, so that the long-time storage of articles is very unfavorable.

Detailed Description
Other advantages and effects of the present invention will become apparent to those skilled in the art from the following disclosure, which describes the embodiments of the present invention with reference to specific examples. The invention may be practiced or carried out in other embodiments that depart from the specific details, and the details of the present description may be modified or varied from the spirit and scope of the present invention.
Please refer to fig. 1 to 4. It should be understood that the structures, proportions, sizes, etc. shown in the drawings are for illustration purposes only and should not be construed as limiting the invention to the extent that it can be practiced, since modifications, changes in the proportions, or adjustments of the sizes, which are otherwise, used in the practice of the invention, are included in the spirit and scope of the invention which is otherwise, without departing from the spirit or scope thereof.
Referring to fig. 1, the present invention discloses a refrigerator 10, which includes a refrigerator body 11 and an air duct assembly of the refrigerator 10. The air duct component can be used for solving the problems that when the existing air-cooled refrigerator 10 is used for defrosting, the temperature of a freezing chamber is rapidly increased, and the temperature between the freezing chamber and the defrosting chamber is greatly floated due to supercooling and temperature rise, so that long-time storage of articles is not facilitated.
The air duct assembly of the refrigerator 10 is connected to the box 11, and a refrigerating room is further arranged in the box 11. It will be appreciated that the cooling room is used to generate cool air, and the cool air generated by the cooling room flows into the refrigerator 10 through the air duct assembly.
Referring to fig. 2-4, in one embodiment, the duct assembly may include a top duct assembly 100, a back duct assembly 200, and a cold storage module 300. Wherein the top air duct assembly 100 is located at a top position of the refrigerator 10, and a first air duct 110 is provided in the top air duct assembly 100. A first air outlet 111 is provided at one end of the top duct assembly 100, and a first air inlet 112 is provided at the other end. The first air outlet 111 is connected in the box 11, and the air flow can be discharged from the first air outlet 111 after being allowed to enter the first air duct 110 from the first air inlet 112.
The back air duct assembly 200 is located at a back position of the refrigerator 10, and a second air duct 210 is opened therein. Wherein, a second air outlet 211 is provided at one end of the back air duct assembly 200, and a second air inlet 212 is provided at the other end. Therefore, the air flow may be allowed to enter the second air outlet 211 from the second air inlet 212, but is not limited thereto. When the reverse airflow exists in the second air duct 210, the airflow is allowed to flow from the second air outlet 211 to the second air inlet 212.
It should be noted that the second air outlet 211 and the first air inlet 112 are disposed in communication, and an L-shaped air path is formed between the first air duct 110 and the second air duct 210. Accordingly, the airflow may be allowed to circulate within the first and second air ducts 110, 210. The cold accumulation module 300 is located in a flow path of the air flow, and when the air flow passes through the cold accumulation module 300, the air flow can allow heat exchange with the cold accumulation module 300. For example, when the temperature of the air flow is lower than the cool storage module 300, the air flow may be used to lower the temperature of the cool storage module 300 to absorb the cool energy in the air flow passing through the first air duct 110 or the second air duct 210 through the cool storage module 300. And, when the temperature of the air flow is higher than the cool storage module 300, the cool storage module 300 may serve to reduce the temperature of the air flow flowing therethrough. Therefore, the temperature difference of the air flow entering the case 11 can be effectively reduced by the cold storage module 300 to improve the problem of large temperature floating.
Referring to fig. 2 to 4, in an embodiment, a cooling fan 400 is further allowed to be disposed between the first air duct 110 and the second air duct 210, and the air flow generated by the cooling fan 400 is exhausted through the first air outlet 111 and the second air outlet 211. The air circulation of the air flow in the refrigerator 10 can be effectively improved by the cooling fan 400.
It will be appreciated that, in order to enhance the practical use effect of the present device, a cool storage air outlet 213 may be allowed to be provided on the second air duct 210. The cold accumulation air outlet 213 is located on the shell assembly of the back air duct, and a cold accumulation module 300 is further provided on one side of the cold accumulation air outlet 213. The problem of excessive temperature difference of the air flow discharged from the cool storage air outlet 213 can be effectively improved through the cool storage module 300.
Referring to fig. 2 to 4, in an embodiment, the cold storage module 300 includes a first cold storage unit 310 and a second cold storage unit 320. Wherein the first cold storage die is located on the wind path of the top duct assembly 100 and the second cold storage unit 320 is located on the wind path of the back duct assembly 200. Wherein, the cold accumulation module 300 is provided therein with a cold accumulation agent through which the cold is absorbed. The coolant may be permitted to take freon, but is not limited thereto, and the coolant may be permitted to be determined according to actual needs.
It should be noted that, the first cold storage unit 310 is covered at the top position of the top air duct assembly 100, so as to improve the heat exchange effect of the first cold storage unit 310 during actual use through large-area coverage.
Referring to fig. 2 to 4, in order to improve the heat insulation effect between the air duct assembly of the refrigerator 10 and the cabinet 11. It is permissible that insulation be provided between the top duct assembly 100 and the cabinet 11, and between the back duct assembly 200 and the cabinet 11, respectively. The heat insulating material may be a sealing sponge, but is not limited thereto, and may be allowed to be determined according to actual needs.
It should be noted that during the installation of the air duct assembly of the refrigerator 10, the cold storage module 300 and the back air duct may be assembled first, and the top cold storage module 300 and the top air duct assembly 100 may be installed second.
In summary, the present invention discloses an air duct assembly of a refrigerator 10 and the refrigerator 10 using the same. During normal operation of the refrigerator 10, the cold storage agent in the cold storage module 300 is cooled. When the refrigerator 10 stops refrigerating or the refrigerator 10 is in a defrosting state, the cold accumulation module 300 refrigerates the refrigerator body 11 for the original refrigeration, improves the absorption efficiency of cold air cooling capacity, ensures that the refrigerating effect of cold air on compartments is more uniform, and has a simple structure and strong operability. The direct blowing of cold air to articles can be effectively avoided through the air outlets, and supercooling and air drying phenomena are avoided. And, by arranging the first cold accumulation unit 310 and the second cold accumulation unit 320 at different positions of the air duct assembly, the air sent by the cooling fan 400 passes through the cold accumulation module 300, so that the cooling effect of the compartment is more uniform.
Therefore, the problems that the temperature of the freezing chamber is rapidly increased, and the temperature between the freezing chamber and the defrosting chamber is greatly floated due to supercooling and temperature rise of defrosting in defrosting of the conventional air-cooled refrigerator 10, which are unfavorable for long-time storage of articles, can be effectively solved.
Therefore, the invention effectively overcomes some practical problems in the prior art, thereby having high utilization value and use significance.
The above embodiments are merely illustrative of the principles of the present invention and its effectiveness, and are not intended to limit the invention. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the invention. Accordingly, it is intended that all equivalent modifications and variations of the invention be covered by the claims, which are within the ordinary skill of the art, be within the spirit and scope of the present disclosure.
