The other end of the air duct 22 is located on the top wall 11 of the receiving cavity 10 and extends toward the opening 12. An ion device 30 is located inside the air duct assembly 20. The ion device 30 is configured such that fluid flowing to the receiving cavity 10 through the air duct assembly 20 passes through the ion device 30. The air duct 22 forms an air inlet and an air outlet 23. The fan 21 is located at the air inlet, and the ion device 30 is located at at least one of the fan 21 and the air outlet 23.

[0035] Combination Figures 1-3The box body 100 is a main part of the refrigerator and is used for storing food and other articles. A containing cavity 10 is formed inside the box body 100. The containing cavity 10 has a top wall 11 on the upper side wall along the first direction A of the refrigerator. An opening 12 is formed on the side wall along the second direction B of the refrigerator. A door body is arranged at the opening 12 to facilitate opening or closing of the opening 12. A fan 21 is arranged on the other side wall along the second direction B of the containing cavity 10. At least part of an air duct 22 is arranged on the other side wall along the second direction B of the containing cavity 10. One end of the air duct 22 is communicated with the fan 21. At least part of the air duct 22 is arranged on the top wall 11 along the first direction A of the containing cavity 10. The other end of the air duct 22 extends along the second direction B towards the side where the opening 12 is located. The other end of the air duct 22 is arranged on the top wall 11 along the second direction B adjacent to the side where the opening 12 is located. The air duct 22 can include two air ducts 22. The two air ducts 22 are arranged at intervals along the third direction C of the refrigerator. One end of each of the two air ducts 22 is communicated with the fan 21. The other end of each of the two air ducts 22 is formed with an air outlet 23. The air outlets 23 of the two air ducts 22 are communicated.

[0036] The fan 21 generates airflow when working and the airflow enters the air duct 22. The air duct 22 is provided with an ion device 30. The airflow flows through the ion device 30 when flowing in the air duct 22. The ion device 30 purifies the air and can remove odors or bacteria in the air, thereby improving the quality of the internal environment of the refrigerator.

[0037] According to the refrigerator of the embodiment of the present application, the ion device 30 is arranged in the air duct assembly 20 of the refrigerator. The ion device 30 can purify the airflow flowing in the air duct 22, so that the air in the containing cavity 10 is cleaner. The ion device 30 is arranged at at least one of the fan 21 and the air outlet 23, which can effectively improve the air purification effect of the ion device 30, further improve the quality of the internal air of the refrigerator, and improve the user experience.

[0038] According to some embodiments of the present application, as shown in Figures 1-7 The air outlet 23 is arranged on the top wall 11 of the containing cavity 10 and adjacent to the opening 12. The ion device 30 is arranged at the air outlet 23. The air outlet 23 is configured to flow fluid along the height direction of the box body 100 towards the containing cavity 10 through the air outlet 23.

[0039] The fan 21 generates air flow when working, and sends the air into the air duct 22 and then into the containing cavity 10 for circulation. The air outlet 23 has a certain flow guide effect, and can guide the fluid to flow to the inside of the containing cavity 10. The ion device 30 is installed at the position of the air outlet 23, so that the air flows from the air duct 22 to the ion device 30, increases the air exchange efficiency and the oxygen content, and can improve the generation efficiency of negative ions, drive the diffusion of ions, and form an ion barrier.

[0040] Therefore, the air outlet 23 is arranged on the top wall 11 of the containing cavity 10 and adjacent to the opening 12, so that the clean air treated by the ion device 30 can directly flow to the top area of the containing cavity 10, so as to better cover the entire containing cavity 10. The ion device 30 is suitable for purifying the air flowing through the air duct 22, such as removing odor, killing bacteria, etc., to improve the quality of the internal environment of the refrigerator. The ion device 30 is arranged at the air outlet 23, so as to ensure that the air flowing into the containing cavity 10 is subjected to purification treatment, ensure the air purification effect, help to keep the internal environment of the refrigerator clean and sanitary, and promote air circulation.

[0041] According to some embodiments of the present application, as shown in Figure 4 and Figure 5 The ion device 30 comprises a first control plate 31 and at least one first needle-shaped electrode 32. One end of the first needle-shaped electrode 32 is electrically connected to the first control plate 31, and the other end of the first needle-shaped electrode 32 extends away from the first control plate 31 along a direction perpendicular to the first control plate 31.

[0042] The first control plate 31 is electrically connected to the first needle-shaped electrode 32 and is responsible for controlling the current passing through the first needle-shaped electrode 32. One end of the first needle-shaped electrode 32 is electrically connected to the first control plate 31, and the other end extends away from the control plate along a direction perpendicular to the control plate. The first control plate 31 extends along the third direction C of the refrigerator, and the first needle-shaped electrode 32 can be multiple. The multiple first needle-shaped electrodes 32 are uniformly spaced on the first control plate 31 along the extension direction of the first control plate 31, which can increase the discharge area and improve the generation amount of negative ions.

[0043] The design of the needle-shaped shape is beneficial to the generation of corona discharge phenomenon when high voltage is applied, so as to generate a large amount of positive ions or negative ions. Needle-shaped discharge is a form of corona discharge. When under the action of a strong electric field, the place with large curvature of the surface of an object (such as the top of a sharp and small object), the equipotential surface is dense, and the electric field strength increases sharply, so that the air near it is ionized to produce gas discharge.

[0044] When the first control panel 31 is powered on, a high voltage will be applied to the first needle tip electrode 32. Due to the small radius of curvature of the needle tip, a very strong high-voltage electric field strength is generated in this area, causing the air molecules around the needle tip to ionize, release electrons and form active substances such as a large number of negative ions and ozone. The generated ions are sent into the refrigerator interior space along with the airflow generated by the fan 21, which can adsorb small particulate matter (such as dust, bacteria, etc.) in the air, making it too heavy to settle down, or directly reacting with certain harmful substances, thereby achieving the effect of purifying the air. Active substances have strong oxidizing and reducing properties and can destroy the cell structure of microorganisms such as bacteria and viruses, thereby achieving the effect of degerming and deodorizing.

[0045] Thus, the ion device 30 can quickly destroy the cell wall and cell membrane of microorganisms such as bacteria and viruses by generating negative ions and ozone and other active substances through the application of needle tip discharge principle, so that they lose activity, thereby achieving the effect of high-efficiency degerming, and can also react with odor molecules in the air to decompose them into harmless substances, thereby quickly eliminating odors. The needle tip discharge degerming and deodorizing technology does not require additional chemical agents or energy consumption, but can achieve air purification and sterilization through a high-voltage electric field, has the characteristics of energy saving and environmental protection. The technology uses a physical method for air purification and sterilization, does not produce harmful substance residues, is harmless to the human body and the environment, and is safe and reliable.

[0046] According to some embodiments of the present application, as shown in Figure 4 and Figure 5 Further comprising: an auxiliary electrode 33, the auxiliary electrode 33 is electrically connected with the first control panel 31, the auxiliary electrode 33 is arranged adjacent to the first needle tip electrode 32, and the auxiliary electrode 33 is opposite to the first needle tip electrode 32 along the thickness direction of the first control panel 31.

[0047] The auxiliary electrode 33 is arranged opposite to the first needle tip electrode 32 and is electrically connected with the first control panel 31, and such an arrangement forms a more stable electric field environment. When a high voltage is applied, the needle tip electrode serves as the main discharge point, and the auxiliary electrode 33 helps maintain the electric field strength to ensure that the corona discharge phenomenon is more stable and efficient. The presence of the auxiliary electrode 33 helps optimize the electric field distribution, so that more air molecules can be effectively ionized to generate more negative ions or ozone and other active substances, thereby improving the effect of air purification and sterilization.

[0048] Therefore, by arranging the auxiliary electrode 33, the discharge process of the first needle electrode 32 can be further guided and enhanced, the arrangement of the auxiliary electrode 33 changes the electric field distribution, so that the electric field intensity near the needle tip is more concentrated, so that the discharge is more easily triggered and maintained, and the unstable factors that may occur when the needle tip electrode works alone, such as local overheating or uneven discharge, can be reduced, thereby prolonging the service life of the entire ion device 30. Appropriately increasing the voltage applied between the needle tip and the auxiliary electrode 33 within a safe range can increase the electric field intensity, promote the ionization of air molecules, and in turn increase the amount of negative ions generated.

[0049] According to some embodiments of the present application, as shown in Figure 5 The auxiliary electrode 33 includes a first connecting portion 331 and at least one second connecting portion 332. The first connecting portion 331 is formed with a hollow portion opposite the first needle electrode 32. The second connecting portion 332 is arranged between the first connecting portion 331 and the first control plate 31, and is used to connect the first connecting portion 331 and the first control plate 31.

[0050] The first connecting portion 331 can be annular in structure, and the first connecting portion 331 is formed with a hollow portion in the middle, which is arranged opposite the first needle electrode 32 along the extension direction of the first needle electrode 32. The second connecting portion 332 extends along the extension direction of the first needle electrode 32, one end of the second connecting portion 332 is connected with the first control plate 31, and the other end of the second connecting portion 332 is connected with the first connecting portion 331. The second connecting portion 332 can be multiple, and the multiple second connecting portions 332 are arranged at intervals around the first needle electrode 32.

[0051] Therefore, the arrangement of the first connecting portion 331 helps to form a more uniform and concentrated electric field around the first needle electrode 32, and the second connecting portion 332 is suitable for providing mechanical support for the first connecting portion 331 and also as part of the electrical connection, ensuring that the current can be transmitted from the first control plate 31 to the first connecting portion 331, making the electric field near the needle tip more concentrated and uniform, and improving the discharge efficiency. Through the design of the first connecting portion 331 and the second connecting portion 332, the auxiliary electrode 33 not only optimizes the electric field distribution and improves the efficiency of the corona discharge, but also enhances the stability and durability of the system.

[0052] According to some embodiments of the present application, as shown in Figure 9 The fan 21 is arranged adjacent to the air inlet, and the fan 21 is connected with the box body 100. The fan 21 includes a driving member and a fan blade 211. The fan blade 211 is connected with the driving member. The ion device 30 is arranged on the fan blade 211 and adjacent to the central area of the fan 21.

[0053] The driving member is adapted to provide power for the fan 21, the fan blade 211 is connected with the driving member, and the driving member drives the fan blade 211 to rotate to generate air flow. The ion device 30 is arranged on the fan blade 211 and located near the central region of the fan 21. When the fan blade 211 rotates, the ions can be quickly and uniformly diffused in multiple directions. With the air flow of the fan 21, the ions can be more quickly spread to a larger space range, and the contact opportunity of the ions and the particulate matters in the air is increased.

[0054] Therefore, the integrated design of the fan 21 and the ion device 30 can effectively quickly spread the generated negative ions or other charged particles to the surrounding environment through air flow, and improve the sterilization and deodorization effect on the air in the refrigerator containing cavity 10.

[0055] According to some embodiments of the present application, as shown in Figure 10 The fan blade 211 is provided with a plurality of air deflectors, the plurality of air deflectors extends along the circumference of the fan 21, and adjacent two air deflectors define a flow channel. The ion device 30 is arranged at one end of the flow channel adjacent to the central region of the fan 21.

[0056] The plurality of air deflectors are uniformly and spacedly distributed along the circumference of the fan 21, and a flow channel is formed between adjacent two air deflectors for guiding air flow. The ion device 30 is arranged at one end of the flow channel adjacent to the central region of the fan 21. When the fan blade 211 rotates, the charged particles (such as negative ions) generated by the ion device 30 can be uniformly dispersed into the air through the flow channel. Since the ion device 30 is located at the starting end of the flow channel, the charged particles can be quickly and uniformly blown into the entire containing cavity 10 along with the air flow.

[0057] Therefore, placing the ion device 30 at the front end of the flow channel can reduce the obstruction to the air flow, thereby improving the overall efficiency of the fan 21. The air deflectors help to guide the air flow, reduce turbulence, and improve the working efficiency of the fan 21. Through the design of the air deflectors and the flow channel, the air flow can be more uniform, and the ion distribution can also be more uniform, thereby improving the diffusion efficiency of the ions and improving the air purification and sterilization effect.

[0058] According to some embodiments of the present application, as shown in Figure 10 The ion device 30 comprises at least one second control plate 34, a plurality of second needle-point electrodes 35 and / or a plurality of carbon fiber electrodes 36. The plurality of second needle-point electrodes 35 are electrically connected with the second control plate 34 and are spacedly arranged along the circumference of the fan 21. The plurality of carbon fiber electrodes 36 are electrically connected with the second control plate 34 and are spacedly arranged along the circumference of the fan 21.

[0059] The ion device 30 comprises a plurality of second control plates 34, at least one second needle electrode 35 is arranged on each second control plate 34, and the plurality of second control plates 34 provided with the second needle electrode 35 are arranged along the circumference of the fan 21 at intervals; or some of the second control plates 34 are provided with the second needle electrode 35, some of the second control plates 34 are provided with a carbon fiber electrode 36, and the plurality of second control plates 34 provided with the second needle electrode 35 and the plurality of second control plates 34 provided with the carbon fiber electrode 36 are arranged along the circumference of the fan 21 at intervals; or the second control plate 34 is provided with the carbon fiber electrode 36, and the plurality of second control plates 34 provided with the carbon fiber electrode 36 are arranged along the circumference of the fan 21 at intervals.

[0060] The carbon fiber electrode 36 is electrically connected with the second control plate 34, so as to ensure that the carbon fiber electrode 36 can work when high voltage is applied. The carbon fiber electrode 36 can generate negative ions through corona discharge, and has a certain adsorption capacity to capture fine particulate matters in the air. The application of the carbon fiber electrode 36 can improve the uniformity of the distribution of negative ions to a certain extent, and is helpful to realize balanced improvement of air quality in the entire accommodating cavity 10. Meanwhile, the carbon fiber electrode 36 has a very high strength-weight ratio, so that the carbon fiber electrode 36 can reduce the overall weight while ensuring the strength, which is conducive to reducing the vibration and noise of the fan 21.

[0061] Therefore, by integrating the plurality of second needle electrodes 35 and the carbon fiber electrodes 36 on the fan 21, the uniformity and efficiency of ion generation are optimized, and the air purification and sterilization effect are improved.

[0062] According to some embodiments of the present application, as shown in Figure 10 The plurality of second needle electrodes 35 and the carbon fiber electrodes 36 are staggered along the circumference of the fan 21.

[0063] The plurality of second needle electrodes 35 and the carbon fiber electrodes 36 are staggered along the circumference of the fan 21, and the plurality of electrodes are uniformly and evenly distributed along the circumference of the fan 21. Through the combined use of the second needle electrode 35 and the carbon fiber electrode 36, more negative ions and active substances can be generated, and the air purification and sterilization effect is improved. The plurality of second needle electrodes 35 and the carbon fiber electrodes 36 are staggered along the circumference of the fan 21, so as to ensure the uniformity of ion generation and improve the overall purification effect.

[0064] Specifically, in practical applications, the radius of curvature of the needle tip has a significant impact on the distribution of the electric field. By precisely designing the shape and size of the needle tip, the electric field can be more concentrated, thereby improving the ionization efficiency and generating more negative ions. Introducing or controlling specific gas components, such as increasing the oxygen content, in the discharge region can improve the efficiency of negative ion generation. Because negative ions are mainly formed by the combination of electrons and oxygen molecules. Humidity and temperature have a significant impact on the discharge process. By adjusting the environmental humidity and temperature of the discharge region, the discharge conditions can be optimized to promote the generation of negative ions. Using a pulse power source instead of a traditional direct current power source can achieve precise control of the discharge process. Pulse discharge can generate a high-intensity electric field in a short time, promoting the ionization of air molecules and improving the efficiency of negative ion generation. Using a high-efficiency and stable power supply design can provide stable voltage and current output, ensuring the stability and reliability of the discharge process. At the same time, by optimizing the output characteristics of the power supply, the efficiency of negative ion generation can also be improved. The performance of the rectifier filter circuit has a significant impact on the purity and stability of the high-voltage direct current. By improving the design of the rectifier filter circuit, the impact of stray current and voltage fluctuations on the discharge process can be reduced, and the efficiency of negative ion generation can be improved.
