[0039] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0040] During the operation of the refrigerator, due to the circulation of refrigerant and the influence of the external environment, condensation may occur in certain parts inside and outside the refrigerator, especially near the freezer door. Condensation in the refrigerator may cause the following hazards:

[0041] 1. Impact on refrigerator performance:

[0042] Condensation will lower the temperature around the refrigerator door, increase the heat load of the refrigerator, cause the refrigeration system to start frequently, increase power consumption, and reduce refrigeration efficiency. It will also affect the uniformity of the temperature inside the refrigerator, which is not conducive to the preservation of food.

[0043] 2. Damage to refrigerator parts:

[0044] Long-term condensation will make the refrigerator door, cabinet and other parts damp, causing the surface paint to fall off and rust, shortening the service life of the refrigerator. In addition, condensation may also penetrate into the interior of the refrigerator, causing short circuits and damage to electrical components, affecting the normal operation of the refrigerator.

[0045] 3. Breeding of bacteria:

[0046] The water droplets formed by condensation will provide a suitable living environment for bacteria, which is easy to breed bacteria and mold. Not only will it produce odor, it may also contaminate the food in the refrigerator and pose a threat to human health.

[0047] 4. Potential safety hazards:

[0048] If condensation is severe, water droplets may drip onto the ground, making the ground slippery and easily causing people to slip and fall.

[0049] The present application provides a novel anti-condensation air duct assembly for refrigerators. The air duct assembly reasonably distributes the arrangement of the air ducts so that the wind in the compressor compartment can blow to the parts near the door body that are prone to condensation, thereby preventing the increase in power consumption due to the increase in the heat load of the refrigerator and reducing the cost of the refrigerator product.

[0050] The specific structure of the refrigerator anti-condensation air duct assembly and the refrigerator provided in the present application is described in detail below in conjunction with the accompanying drawings.

[0051] Reference Figure 1-Figure 3 As shown, the embodiment of the present application provides a refrigerator anti-condensation air duct assembly, including a machine compartment 11, which can be a rectangular box, a refrigeration device is arranged in the machine compartment 11, and a condensation air inlet 111 and a condensation air outlet 112 are respectively arranged on both sides of the machine compartment 11. The refrigeration device releases heat to generate hot air flow when working, and the hot air flow is discharged from the machine compartment 11 through the condensation air outlet 112, and the external air enters the machine compartment 11 through the condensation air inlet 111;

[0052] The anti-condensation air duct 2 communicated with the machine compartment 11, the anti-condensation air duct 2 includes an air duct body 201, one end of the air duct body 201 is provided with an air inlet 202, and the other side is provided with a plurality of air outlets 203, the air inlet 202 is connected to the condensation air outlet 112, and the air outlet 203 is located at the lower part of the refrigerator door body and corresponds to the vertical gap of the refrigerator door body;

[0053] The hot air flow flows through the condensation air outlet 112, the air inlet 202 and the air outlet 203 in sequence, and blows toward the gap between the door body and the cabinet, thereby increasing the temperature near the refrigerator door body and avoiding condensation.

[0054] An anti-condensation air duct assembly for a refrigerator provided in an embodiment of the present application reasonably distributes the arrangement of the air ducts so that the wind in the compressor compartment can blow to the parts near the door body that are prone to condensation, thereby preventing an increase in power consumption due to an increase in the heat load of the refrigerator and reducing the cost of the refrigerator product.

[0055] Reference Figure 3 As shown, in some embodiments, the machine compartment 11 is a compressor compartment, and a condenser 101, a condensing fan 102 and a compressor 103 are provided in the machine compartment 11;

[0056] The condenser 101, the condensing fan 102 and the compressor 103 all release heat during operation. The specific process is as follows:

[0057] The compressor is the core component of the refrigeration system. It compresses the refrigerant to increase its pressure and temperature. During the compression process, the compressor motor generates heat, and the refrigerant also increases its internal energy when it is compressed, causing the temperature to rise. This heat will be dissipated into the surrounding environment through the compressor casing.

[0058] The high-temperature and high-pressure refrigerant gas discharged from the compressor enters the condenser. In the condenser, the refrigerant exchanges heat with the surrounding environment, transferring heat to the outside air or cooling water, and gradually cools itself and condenses into liquid. In this process, the heat released by the refrigerant is dissipated to the surrounding environment through the tube wall and heat sink of the condenser.

[0059] The function of the condensing fan is to accelerate the air flow around the condenser and improve the heat dissipation effect of the condenser. When the condensing fan is running, the motor itself will generate a certain amount of heat. At the same time, it pushes the air to flow quickly through the condenser, taking away the heat emitted by the condenser, and then releasing the heat into the surrounding environment.

[0060] The condenser 101 and the compressor 103 release heat when working, and the condensing fan 102 blows air toward the condensing air outlet 112 to generate a hot air flow, and the hot air flow is discharged from the nacelle 11 through the condensing air outlet 112 .

[0061] When the cabinet is running, the heat from the condenser and compressor is blown to the gap between the door and the cabinet through the anti-condensation air duct due to the action of the condensing fan, avoiding the risk of condensation, reducing the leakage of anti-condensation heat into the refrigerator, and reducing the energy consumption of the refrigerator.

[0062] Reference Figure 3 As shown, in some embodiments, the condensing fan 102 is fitted around the inner wall of the compressor compartment to separate the compressor compartment into a first compartment and a second compartment, and the condensing air inlet 111 and the condensing air outlet 112 are respectively connected to the first compartment and the second compartment.

[0063] In some embodiments, the condenser 101 and the compressor 103 are respectively located on both sides of the condensing fan 102, that is, the condenser 101 and the compressor 103 are respectively arranged in the first compartment and the second compartment;

[0064] The condensation air inlet 111 and the condensation air outlet 112 are respectively connected to the first cabin and the second cabin, and the condenser 101 and the compressor 103 are respectively arranged in the first cabin and the second cabin;

[0065] The heat released by the condenser 101 and the compressor 103 heats the air in the first compartment and the second compartment respectively. When the condensing fan 102 is working, it blows air toward the condensation air outlet 112, so that the hot air in the first compartment enters the second compartment, or the hot air in the second compartment enters the first compartment, and is discharged from the machine compartment 11 through the condensation air outlet 112 and blown toward the parts near the door body that are prone to condensation, thereby preventing the increase in power consumption caused by the increase in the heat load of the refrigerator and reducing the cost of the refrigerator product.

[0066] Reference Figure 1 As shown, in some embodiments, the air duct body 201 includes a connecting portion and an exhaust portion, and the specific structures of the connecting portion and the exhaust portion are not limited;

[0067] One end of the connecting portion is provided with an air inlet 202, and the other end of the connecting portion is connected to the exhaust portion;

[0068] The exhaust part can be a strip-shaped air duct, which cooperates with the bottom gap between the door body and the refrigerator body. The upper surface of the exhaust part is provided with a plurality of the air outlets 203, and the plurality of the air outlets 203 are evenly distributed along the length direction of the exhaust part.

[0069] In some embodiments, the anti-condensation air duct 2 is an integrated structure;

[0070] The anti-condensation air duct 2 is detachably connected to the cabin 11 .

[0071] Reference Figure 2 As shown, in some embodiments, the condensation air inlet 111 of the cabin 11 faces the exhaust part;

[0072] In the present application, the condensation air inlet 111 of the cabin 11 is designed to be oriented toward the exhaust portion and arranged close to the air outlet 203 of the anti-condensation air duct 2, which has the following advantages:

[0073] 1. During operation, the hot air in the machine compartment 11 is discharged from the condensation air outlet 112 and blown toward the parts near the door body that are prone to condensation, specifically toward the bottom gap between the door body and the refrigerator body. At this time, the air pressure at the lower part of the door body increases, and the condensation air inlet 111 is arranged close to the air outlet 203 and the lower part of the door body, so that the external air can enter the machine compartment 11 through the condensation air inlet 111;

[0074] 2. It facilitates the entry of external air into the machine compartment 11 while reducing the amount of excessive air blown forward from the bottom of the refrigerator to avoid affecting user use.

[0075] 3. The exhausted hot air flows back into the machine compartment 11 to realize air circulation, increase the temperature of the air entering the machine compartment 11, increase the temperature of the air discharged from the machine compartment 11, and thus improve the anti-condensation effect.

[0076] The present application proposes a novel anti-condensation air duct assembly for refrigerators. The air duct assembly reasonably distributes the arrangement of the air ducts so that the wind in the compressor compartment can blow to the parts near the door body that are prone to condensation, thereby preventing the increase in power consumption due to the increase in the heat load of the refrigerator and reducing the cost of the refrigerator product.

[0077] Reference Figure 4 As shown, the present application provides a refrigerator, comprising: a box body 1 and a refrigerator anti-condensation air duct assembly as described above, which is arranged on the box body 1.

[0078] The refrigerator body is mainly composed of two parts: the outer shell and the inner tank:

[0079] The outer shell is usually made of cold-rolled steel plate or galvanized steel plate, and the surface is sprayed or coated. It has good strength and corrosion resistance, can protect the internal structure of the refrigerator, and also play a certain decorative role.

[0080] The inner tank is generally made of engineering plastics (such as ABS, HIPS, etc.) or stainless steel. It has a smooth surface, is easy to clean, has good low-temperature resistance, can withstand the low-temperature environment inside the refrigerator, and will not react chemically with food, ensuring the safety and freshness of food. Insulation materials such as polyurethane foam are also filled between the inner tank and the outer shell to reduce heat transfer and improve the insulation effect of the refrigerator.

[0081] In some embodiments, a relief position is provided at the lower rear portion of the inner tank, and the relief position may be a rectangular parallelepiped. The engine compartment 11 is disposed in the relief position, and the inner tank and the engine compartment 11 are encapsulated in an outer shell.

[0082] The open end of the box body 1 is provided with a door body, the anti-condensation air duct 2 is located at the lower part of the box body 1, and the air outlet 203 faces the gap between the box body 1 and the door body.

[0083] The refrigerator provided in the present application avoids the risk of condensation by drawing air from the compressor compartment to blow directly to the areas near the freezer door that are prone to condensation. By reasonably distributing the air ducts, the wind in the compressor compartment can blow to the parts near the door that are prone to condensation, thereby preventing the increase in power consumption due to the increase in the heat load of the refrigerator and reducing the cost of the refrigerator product.
