Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, and in particular to a refrigerator anti-condensation air duct assembly and a refrigerator. Background Technology

[0002] During the operation of a refrigerator, condensation may occur on certain parts inside and outside the refrigerator due to the circulation of refrigerant and the influence of the external environment, especially near the freezer door. Condensation near the refrigerator door can affect the appearance and lifespan of the refrigerator, increase energy consumption and cooling burden, breed bacteria and produce odors, and also pose safety hazards.

[0003] Existing refrigerators have anti-condensation pipes installed around the door frame. These pipes use hot refrigerant fluid as a heat source to heat the refrigerator door frame, thus preventing condensation. However, the heat from the anti-condensation pipes is also transferred to the refrigerator interior, increasing the refrigerator's heat load and consequently increasing power consumption. Summary of the Invention

[0004] This application provides a refrigerator anti-condensation air duct assembly and a refrigerator. The air duct assembly, through the reasonable distribution of the air duct arrangement, ensures that the air in the compressor compartment can blow to the components near the door that are prone to condensation, preventing the increase in power consumption caused by the increased heat load of the refrigerator, reducing the cost of the refrigerator product, and solving the problem that existing anti-condensation methods will lead to increased power consumption and increased refrigerator costs.

[0005] In a first aspect, embodiments of this application provide a refrigerator anti-condensation air duct assembly, comprising:

[0006] The machine compartment is equipped with refrigeration equipment. Condensation air inlets and condensation air outlets are respectively provided on both sides of the machine compartment. When the refrigeration equipment is working, it releases heat to generate hot airflow. The hot airflow is discharged from the machine compartment through the condensation air outlets, and outside air enters the machine compartment through the condensation air inlets.

[0007] The anti-condensation air duct includes an air duct body, an air inlet at one end of the air duct body, and several air outlets on the other side. The air inlet is connected to the condensation air outlet, and the air outlets are located at the bottom of the refrigerator door and correspond to the vertical gap of the refrigerator door.

[0008] The hot airflow flows sequentially through the condenser outlet, the air inlet, and the air outlet, and blows towards the gap between the door and the cabinet, thereby increasing the temperature near the refrigerator door and preventing condensation.

[0009] This application provides a refrigerator anti-condensation air duct assembly, which, through the reasonable distribution of the air duct layout, ensures that the air in the compressor compartment can blow to the components near the door that are prone to condensation, thereby preventing increased power consumption due to increased refrigerator heat load and reducing the cost of refrigerator products.

[0010] In one feasible implementation, the housing is a compressor housing, which contains a condenser, a condensing fan, and a compressor.

[0011] The condenser and compressor release heat during operation. Specifically, the compressor motor generates heat, and the refrigerant's internal energy increases as it is compressed, causing its temperature to rise. This heat is dissipated into the surrounding environment through the compressor's casing. The refrigerant exchanges heat with the surrounding environment, transferring heat to the outside air or cooling water, while gradually cooling and condensing into a liquid. During this process, the heat released by the refrigerant is dissipated into the surrounding environment through the condenser's tube walls and heat sink fins.

[0012] The condenser fan blows air toward the condenser outlet to generate a hot airflow, and the hot airflow is discharged from the condenser outlet into the machine compartment.

[0013] In one feasible implementation, the condenser fan is fitted to the inner wall of the compressor compartment to divide the compressor compartment into a first compartment and a second compartment, and the condenser air inlet and the condenser air outlet are respectively connected to the first compartment and the second compartment.

[0014] The condenser fan is fitted against the inner wall of the compressor compartment to divide the compressor compartment into a first compartment and a second compartment, facilitating the rapid exhaust of hot air from the compartment.

[0015] In one feasible implementation, the condenser and the compressor are located on opposite sides of the condenser fan, that is, the condenser and the compressor are respectively installed in the first compartment and the second compartment;

[0016] When the condenser fan is working, it blows air into the condenser outlet, causing hot air from the first compartment to enter the second compartment, or vice versa, and then exhausts the air from the condenser outlet into the machine compartment. The air is then blown towards components near the door that are prone to condensation, preventing increased power consumption due to increased heat load on the refrigerator and reducing the cost of the refrigerator product.

[0017] In one feasible implementation, the duct body includes a connecting part and an exhaust part;

[0018] One end of the connecting part is provided with an air inlet, and the other end of the connecting part is connected to the exhaust part;

[0019] The exhaust section is a strip-shaped air duct, and the upper surface of the exhaust section is provided with multiple air outlets, which are evenly distributed along the length of the exhaust section.

[0020] In one feasible implementation, the anti-condensation duct is an integral structure.

[0021] In one feasible implementation, the anti-condensation air duct is detachably connected to the nacelle.

[0022] In one feasible implementation, the condenser air inlet of the nacelle faces the exhaust section;

[0023] The hot air discharged from the air outlet enters the machine compartment through the condenser air inlet, thereby achieving air circulation.

[0024] Secondly, embodiments of this application provide a refrigerator, including a cabinet and a refrigerator anti-condensation air duct assembly as described above disposed on the cabinet.

[0025] The refrigerator provided in this application avoids the risk of condensation by drawing air directly from the compressor compartment to the area near the freezer door that is prone to condensation. By rationally distributing the air ducts, the air in the compressor compartment can reach the components near the door that are prone to condensation, preventing increased power consumption due to increased refrigerator heat load and reducing the cost of the refrigerator product.

[0026] In one feasible implementation, a clearance space is provided on the lower rear side of the housing, and the nacelle is located within the clearance space.

[0027] In one feasible implementation, the open end of the housing is provided with a door, the anti-condensation air duct is located at the lower part of the housing, and the air outlet faces the gap between the housing and the door.

[0028] This application provides a refrigerator anti-condensation air duct assembly and a refrigerator. The refrigerator is equipped with a refrigeration device in the compartment. A condensation air inlet and a condensation air outlet are respectively provided on both sides of the compartment. The anti-condensation air duct includes an air duct body. An air inlet is provided at one end of the air duct body, and a plurality of air outlets are provided on the other side. The air inlet is connected to the condensation air outlet. The air outlets are located at the lower part of the refrigerator door and correspond to the vertical gap of the refrigerator door. When the refrigeration device is working, it releases heat to generate a hot airflow. The hot airflow flows through the condensation air outlet, the air inlet and the air outlet in sequence and blows towards the gap between the door and the refrigerator body to avoid the risk of condensation.

[0029] The novel refrigerator anti-condensation air duct assembly provided in this application, through the reasonable distribution of the air duct arrangement, ensures that the air in the compressor compartment can blow to the parts near the door that are prone to condensation, thereby preventing the increase in power consumption caused by the increased heat load of the refrigerator and reducing the cost of the refrigerator product.

[0030] The refrigerator provided in this application avoids the risk of condensation by drawing air directly from the compressor compartment to the area near the freezer door that is prone to condensation. By rationally distributing the air ducts, the air in the compressor compartment can reach the components near the door that are prone to condensation, preventing increased power consumption due to increased refrigerator heat load and reducing the cost of the refrigerator product.

[0039] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

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

[0041] 1. Affects refrigerator performance:

[0042] Condensation lowers the temperature around the refrigerator door, increasing the refrigerator's heat load, causing the refrigeration system to start frequently, increasing power consumption, and reducing refrigeration efficiency. It also affects the uniformity of the internal temperature of the refrigerator, which is not conducive to food preservation.

[0043] 2. Damaged refrigerator parts:

[0044] Prolonged condensation can cause moisture buildup on the refrigerator door and body, leading to paint peeling, rust, and a shortened lifespan. Furthermore, condensation can seep into the refrigerator's interior, causing short circuits and damage to electrical components, thus affecting the refrigerator's normal operation.

[0045] 3. Bacterial growth:

[0046] The water droplets formed by condensation provide a suitable living environment for bacteria, making it easy for bacteria and mold to grow. This not only produces odors but may also contaminate the food in the refrigerator, posing a threat to human health.

[0047] 4. Creates safety hazards:

[0048] If condensation is severe, water droplets may drip onto the ground, making it slippery and increasing the risk of people slipping and falling.

[0049] This application provides a novel anti-condensation air duct assembly for refrigerators. By rationally distributing the air ducts, this assembly ensures that the air in the compressor compartment can reach components near the door that are prone to condensation, preventing increased power consumption due to increased refrigerator heat load and reducing the cost of refrigerator products.

[0050] The following detailed description, in conjunction with the accompanying drawings, illustrates the refrigerator anti-condensation air duct assembly and the specific structure of the refrigerator provided in this application.

[0051] Reference Figures 1-3 As shown in the figure, this application embodiment provides a refrigerator anti-condensation air duct assembly, including a compartment 11, which may be a rectangular box. The compartment 11 is equipped with a refrigeration device. The two sides of the compartment 11 are respectively provided with a condensation air inlet 111 and a condensation air outlet 112. When the refrigeration device works, it releases heat to generate a hot airflow. The hot airflow is discharged from the compartment 11 through the condensation air outlet 112, and external air enters the compartment 11 through the condensation air inlet 111.

[0052] The anti-condensation air duct 2 is connected to 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. The air outlets 203 are located at the lower part of the refrigerator door and correspond to the vertical gap of the refrigerator door.

[0053] The hot airflow flows sequentially through the condenser outlet 112, the air inlet 202, and the air outlet 203, and blows towards the gap between the door and the cabinet, thereby increasing the temperature near the refrigerator door and preventing condensation.

[0054] This application provides a refrigerator anti-condensation air duct assembly. By rationally distributing the air ducts, it ensures that the air in the compressor compartment can reach the components near the door that are prone to condensation, preventing increased power consumption due to increased refrigerator heat load 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 the machine compartment 11 is provided with a condenser 101, a condensing fan 102 and a compressor 103;

[0056] The condenser 101, condenser fan 102, and compressor 103 all release heat during operation, as detailed below:

[0057] The compressor is the core component of a refrigeration system. It increases the pressure and temperature of the refrigerant by compressing it. During the compression process, the compressor motor generates heat, and the refrigerant also gains internal energy as it is compressed, causing its temperature to rise. This heat is dissipated into the surrounding environment through the compressor's casing.

[0058] The high-temperature, 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, while gradually cooling and condensing into a liquid. During this process, the heat released by the refrigerant is dissipated into the surrounding environment through the condenser's pipe walls and heat sinks.

[0059] The function of a condenser fan is to accelerate the airflow around the condenser, thereby improving the condenser's heat dissipation effect. When the condenser fan is running, the motor itself generates a certain amount of heat, and at the same time, it pushes air to flow quickly through the condenser, carrying away the heat dissipated by the condenser and releasing the heat into the surrounding environment.

[0060] The condenser 101 and the compressor 103 release heat during operation, and the condenser fan 102 blows air toward the condenser outlet 112 to generate hot airflow, and the hot airflow is discharged from the condenser outlet 112 into the hopper 11.

[0061] When the refrigerator is running, the heat from the condenser and compressor is blown towards the gap between the door and the refrigerator body through the anti-condensation air duct by the condenser fan, avoiding the risk of condensation, reducing the leakage of anti-condensation heat into the refrigerator, and reducing the refrigerator's energy consumption.

[0062] Reference Figure 3 As shown, in some embodiments, the condenser fan 102 is fitted around the inner wall of the compressor compartment to divide the compressor compartment into a first compartment and a second compartment, and the condenser air inlet 111 and the condenser 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 located on both sides of the condenser fan 102, that is, the condenser 101 and the compressor 103 are respectively disposed in the first compartment and the second compartment;

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

[0065] The heat released by the condenser 101 and the compressor 103 during operation heats the air in the first compartment and the second compartment, respectively. When the condenser fan 102 is working, it blows air into the condenser outlet 112, so that the hot air in the first compartment enters the second compartment, or so that the hot air in the second compartment enters the first compartment, and is discharged from the condenser outlet 112 into the hopper 11, and blown towards the components near the door that are prone to condensation, so as to prevent the increase in power consumption caused by the increase in the heat load of the refrigerator and reduce the cost of the refrigerator product.

[0066] Reference Figure 1 As shown, in some embodiments, the air duct body 201 includes a connecting part and an exhaust part, and the specific structure of the connecting part and the exhaust part is not limited.

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

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

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

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

[0071] Reference Figure 2 As shown, in some embodiments, the condenser air inlet 111 of the nacelle 11 faces the exhaust section;

[0072] This application designs the condenser air inlet 111 of the nacelle 11 to face the exhaust section and is located near the air outlet 203 of the anti-condensation air duct 2, which has the following advantages:

[0073] 1. During operation, hot air inside the compartment 11 is discharged through the condenser outlet 112 and blown towards the components near the door that are prone to condensation, specifically towards the bottom gap between the door and the refrigerator body. At this time, the air pressure at the bottom of the door increases. The condenser inlet 111 is located close to the outlet 203 and close to the bottom of the door, so that external air can enter the compartment 11 through the condenser inlet 111.

[0074] 2. While facilitating the entry of external air into the compartment 11, it reduces excessive air blowing forward from the bottom of the refrigerator, thus avoiding affecting user operation.

[0075] 3. The exhausted hot air flows back into the hopper 11 to achieve air circulation, increase the temperature of the air entering the hopper 11, increase the temperature of the air exiting the hopper 11, and thus improve the anti-condensation effect.

[0076] This application proposes a novel anti-condensation air duct assembly for refrigerators. This air duct assembly, through the reasonable distribution of the air duct layout, ensures that the air in the compressor compartment can blow to the components near the door that are prone to condensation, thereby preventing increased power consumption due to increased refrigerator heat load and reducing the cost of refrigerator products.

[0077] Reference Figure 4 As shown, this application provides a refrigerator, including: a cabinet 1 and a refrigerator anti-condensation air duct assembly as described above disposed on the cabinet 1.

[0078] The refrigerator body mainly consists of two parts: the outer shell and the inner liner.

[0079] The outer shell is usually made of cold-rolled steel sheet or galvanized steel sheet, and the surface is treated with spraying or coating. It has good strength and corrosion resistance, protects the internal structure of the refrigerator, and also plays a certain decorative role.

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

[0081] In some embodiments, a clearance space is provided at the lower rear side of the inner liner. The clearance space may be a cuboid. The engine compartment 11 is disposed within the clearance space, and the inner liner and the engine compartment 11 are encapsulated within the outer shell.

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

[0083] The refrigerator provided in this application avoids the risk of condensation by drawing air directly from the compressor compartment to the area near the freezer door that is prone to condensation. By rationally distributing the air ducts, the air in the compressor compartment can reach the components near the door that are prone to condensation, preventing increased power consumption due to increased refrigerator heat load and reducing the cost of the refrigerator product.
