Description

Technical Field

[0001] This application relates to the field of home appliance technology, and more particularly to a refrigerator. Background Technology

[0002] As an indispensable home appliance in modern families, refrigerators have become increasingly sophisticated and functional with the development of technology, in order to meet users' needs for food preservation, storage, and other aspects.

[0003] In the process of conceiving and implementing this application, the applicant discovered at least the following problems: Currently, refrigerator doors are equipped with water storage boxes, and inside the water storage boxes are atomizing plates. The atomizing plates atomize and humidify the food inside the refrigerator. As the water storage box is a relatively closed cavity, when the door is opened or closed, due to the imbalance of air pressure inside and outside the water storage box, water will continuously overflow from the micropores of the atomizing plates, resulting in a poor user experience.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

[0005] The main objective of this application is to provide a refrigerator that improves the spill prevention performance of the atomizing component.

[0006] To achieve the above objectives, this application provides a refrigerator, comprising:

[0007] The enclosure includes a refrigeration compartment;

[0008] The door is movably connected to the cabinet and is configured to open and close the refrigeration compartment;

[0009] Atomizing component, located on the door, includes:

[0010] The liquid storage box has vent holes.

[0011] The cover covers the vent hole and has an airflow channel that communicates with the outside of the liquid storage box. The airflow channel is connected to the vent hole.

[0012] The beneficial effects of this application are: by opening a vent hole on the liquid storage box and connecting the vent hole with the airflow channel, the air pressure inside the liquid storage box and the external environment can be balanced in an instant, eliminating the driving force caused by the air pressure difference, thereby preventing liquid from leaking from the micropores of the atomizing component. Especially in scenarios where air pressure fluctuations are easily caused, such as when the door is opened and closed, the overflow prevention performance and reliability of the atomizing component are improved.

[0013] Based on the above technical solution, the following improvements can be made to this application.

[0014] In some alternative embodiments, the cover has a covering surface facing the vent.

[0015] The mating surface is provided with:

[0016] The groove extends to the edge of the cover to form an airflow channel.

[0017] The above technical solution has the following advantages or beneficial effects: by integrating the airflow channel into the groove of the cover surface of the cover, the modularization and concealment of the air pressure balance function are realized. It is not only compact in structure and simple to assemble, but also achieves multiple effects such as ventilation and leakage prevention.

[0018] In some alternative embodiments, the cover is a plastic part; and / or,

[0019] The vent is a conical hole.

[0020] The above technical solution has the following advantages or beneficial effects: Plastic parts are typically injection molded. This means that the grooves on the mating surface can be injection molded in one step without subsequent machining. This reduces production costs, improves efficiency, and ensures precision and consistency.

[0021] In some alternative embodiments, the reservoir has:

[0022] The vent is located in the injection section;

[0023] The cover assembly includes:

[0025] The above technical solution has the following advantages or beneficial effects: it ensures that when the cover is closed, the grooves on its closing surface can be precisely aligned with the vent holes on the liquid injection part, thereby ensuring that the airflow channel can be reliably established every time and avoiding the risk of functional failure due to misalignment.

[0026] In some optional embodiments, the injection section is provided with an injection port;

[0027] The cover assembly also includes:

[0028] A sealing part is connected to the connecting part. The sealing part protrudes towards the liquid storage box and extends into the liquid injection port.

[0029] The above technical solution has the following advantages or beneficial effects: the sealing part and the connecting part are integrated on the same cover piece. The sealing part is used to seal the injection port to meet the sealing requirements, and the groove is connected to the vent hole to meet the air pressure balance requirements.

[0030] In some alternative implementations, the sealing portion is a ring-shaped structure;

[0031] At least a portion of the outer periphery of the sealing part has protrusions.

[0032] The above technical solution has the following advantages or beneficial effects: the protrusion forms a line contact or narrow surface contact with the inner wall of the injection port, providing the main sealing force and preventing a large amount of liquid leakage under normal conditions; the gap between the protrusion and the inner wall of the injection port forms a return channel, which allows the water overflowing from the vent during the opening and closing of the liquid storage box to flow back, thereby solving the problem of water overflow from the liquid storage box.

[0033] In some alternative embodiments, the injection section further includes an annular groove surrounding the outer periphery of the injection port.

[0034] The injection section has a notch, and the annular groove is connected to the injection port through the notch;

[0035] The annular groove is inclined relative to the injection section, and along the height direction of the tank, the groove wall height of the annular groove located at the notch is lower than the groove wall height of the annular groove located at other positions.

[0036] The above technical solution has the following advantages or beneficial effects: the bottom of the annular groove is an inclined plane, or the entire annular groove is inclined relative to the injection port, and the notch is opened at the lowest position of the annular groove wall. Utilizing gravity, any liquid that may enter the annular groove can be automatically collected and guided back to the injection port through the notch, preventing leakage.

[0043] The box has an opening;

[0044] The lid has an opening, and the lid and the box body form a liquid storage cavity;

[0045] The liquid injection section is located on the box lid.

[0046] The above technical solution has the following advantages or beneficial effects: the lid is placed on the opening of the box body, and together with the box body, they form a liquid storage cavity for storing liquid. The liquid injection part is located on the lid and is used to inject liquid into the liquid storage cavity. The entire structural design is easy to manufacture and easy to assemble.

[0047] In some alternative embodiments, the reservoir also includes:

[0048] The cable groove is located on the outside of the liquid storage cavity;

[0049] The reservoir also includes:

[0050] The top cover covers the box body and is located on the upper side of the box lid;

[0051] Along the height of the box, the projection of the lid is located within the projection of the top cover.

[0052] The above technical solution has the following advantages or beneficial effects: the design of the cable tray facilitates the arrangement of the wiring, and is used to organize the power lines or signal lines of the atomizing components (or other components that may be installed on the liquid storage box, such as water level sensors), preventing the cables from being messy, tangled or accidentally pulled, thus improving the internal cleanliness, safety and reliability of the product.

[0053] The refrigerator provided in this application includes a cabinet with a refrigeration compartment; a door movably connected to the cabinet and configured to open and close the refrigeration compartment; and an atomizing assembly disposed on the door. The atomizing assembly includes: a liquid storage box with a vent hole; and a cover covering the vent hole. The cover has an airflow channel communicating with the outside of the liquid storage box, and the airflow channel is connected to the vent hole.

[0054] By opening vents in the liquid storage box and connecting the vents with the airflow channel, the air pressure inside the liquid storage box and the external environment can be balanced in an instant, eliminating the driving force caused by the air pressure difference, thereby preventing liquid from leaking from the micropores of the atomizing component. Especially in scenarios where air pressure fluctuations are easily caused, such as when the door is opened and closed, the overflow prevention performance and reliability of the atomizing component are improved.

[0076] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of 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, not all embodiments.

[0080] Currently, refrigerators have a water storage box on the door, which contains an atomizing plate. The atomizing plate atomizes and humidifies the food inside the refrigerator. However, since the water storage box is a relatively closed cavity, when the door is opened or closed, water will continuously overflow from the micropores of the atomizing plate due to the pressure imbalance inside and outside the water storage box, resulting in a poor user experience.

[0081] In order to overcome the defects in the prior art, the refrigerator provided in this application can instantly balance the air pressure inside the liquid storage box and the external environment by opening a vent hole on the liquid storage box and connecting the vent hole with the airflow channel, thereby eliminating the driving force caused by the air pressure difference and preventing liquid from leaking from the micropores of the atomizing component. Especially in scenarios where air pressure fluctuations are easily caused, such as when the door is opened and closed, the overflow prevention performance and reliability of the atomizing component are improved.

[0082] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0084] like Figures 1 to 7 As shown, this application embodiment provides a refrigerator 100, including:

[0085] The enclosure 110 has a refrigeration compartment;

[0086] The door 120 is movably connected to the cabinet 110 and is configured to open and close the refrigeration compartment;

[0087] Atomizing component 130 is disposed on door body 120. Atomizing component 130 includes:

[0088] The liquid storage box 131 has a vent hole 1311;

[0089] The cover 132 covers the vent 1311. The cover 132 has an airflow channel that communicates with the outside of the liquid storage box 131. The airflow channel is connected to the vent 1311.

[0090] With the above-mentioned configuration, namely, the refrigerator 100 of this application embodiment, by opening a vent 1311 on the liquid storage box 131 and having the vent 1311 connected to the airflow channel, can instantly balance the air pressure inside the liquid storage box 131 and the external environment, eliminate the driving force caused by the air pressure difference, thereby preventing liquid from leaking from the micropores of the atomizing component 133. Especially in scenarios where air pressure fluctuations are easily caused, such as the opening and closing of the door 120, the overflow prevention performance and reliability of the atomizing component 130 are improved.

[0091] It should be noted that the following provides a detailed explanation of each structure.

[0092] [Box 110]

[0093] The refrigerator 100 of this application embodiment may include a cabinet 110 and a door 120. The cabinet 110 may be configured with a refrigeration compartment. The refrigeration compartment has an opening for storing food and other items. There may be one or more refrigeration compartments. When there are multiple refrigeration compartments, the multiple refrigeration compartments may be divided into a refrigerator compartment, a freezer compartment, or a variable temperature compartment, etc.

[0094] For example, the refrigerator body 110 may include an outer shell and an inner liner, the outer shell defining the external boundary of the refrigerator 100. The inner liner may be disposed within and connected to the outer shell. The inner liner may be recessed inward to form a cooling compartment. An insulation layer may be filled between the outer shell and the inner liner, which can insulate the cooling compartment, thereby reducing the energy consumption of the refrigerator 100.

[0095] The box 110 adopts a hollow cuboid structure. It is understood that in other embodiments, the box 110 may also adopt a hollow shell structure of other shapes.

[0096] In some embodiments, a refrigeration assembly (not shown) is provided inside the cabinet 110 to provide cooling for the interior of the refrigerator 100 in order to maintain a low-temperature environment in each refrigeration compartment.

[0097] Refrigeration components include compressors, condensers, evaporators, and throttling devices. The specific structure and connections of these components can be found in relevant technical documentation on refrigeration components, and will not be elaborated upon here. The evaporator provides different amounts of cooling capacity to different types of storage spaces, resulting in varying temperatures within these spaces. For example, the temperature inside a refrigerator is generally between 2°C and 10°C, preferably between 4°C and 7°C. The temperature range inside a freezer is generally between -22°C and -14°C. Different types of items have different optimal storage temperatures, and consequently, different suitable storage spaces. For example, fruits and vegetables are suitable for storage in refrigerators or crisper compartments, while meat is suitable for storage in freezers.

[0098] It should be noted that X represents the width direction of the box 110, and Z represents the height direction of the box 110.

[0099] [Gate 120]

[0100] It should be noted that the door 120 can be connected to the cabinet 110 to open or close the refrigeration compartment.

[0101] A door 120 is disposed on the front surface of the enclosure 110 to enclose the refrigeration compartment. The door 120 is configured to open and close the refrigeration compartment, meaning it can open and close the front opening of the enclosure 110. Doors 120 can be correspondingly assigned to refrigeration compartments; that is, each refrigeration compartment can have one or more doors 120. The number of refrigeration compartments and doors 120, as well as the function of the refrigeration compartments, can be selected based on specific circumstances. One door 120 can be assigned to the same refrigeration compartment. Alternatively, two doors 120 can be assigned to the same refrigeration compartment.

[0102] In some possible implementations of this application, the door 120 can be rotatably connected to the housing 110 about the height direction Z of the housing 110. The door 120 can be pulled or pushed to rotate relative to the housing 110, thereby opening or closing the refrigeration compartment.

[0103] In some embodiments, the door 120 is a rotating door structure. The door 120 is rotatably disposed on the front side of the housing 110, and in this case, the door 120 can be used as a general door structure, such as a refrigerator door, a variable temperature door, etc.

[0104] Specifically, the door 120 and the cabinet 110 can be connected by a hinge so that the door 120 of the refrigerator 100 can rotate around the axis of the hinge, thereby opening and closing the door 120 and opening and closing the corresponding refrigeration compartment.

[0105] In some embodiments, the door 120 can also be a sliding door structure. The door 120 is slidably disposed on the front side of the cabinet 110, and in this case, the door 120 can be used as a drawer door. Specifically, guide rails (not shown in the figure) are respectively provided on the left and right inner side walls of the cabinet liner, and the door 120 is connected to the guide rails on both sides, thereby realizing the sliding function of the door 120 and realizing the opening and closing of the refrigeration compartment by extending and retracting the guide rails.

[0106] [Atomizing Component 130]

[0107] It should be noted that the refrigerator 100 also includes an atomizing component 130, which is located on the door 120. Specifically, it is located on the inside of the door 120 and faces the refrigeration compartment. The atomizing component 130 atomizes and preserves the food in the refrigeration compartment.

[0108] In some embodiments, the refrigerator 100 further includes a mounting bracket 140, the atomizing assembly 130 is mounted on the mounting bracket 140, and the mounting bracket 140 is mounted on the door 120.

[0109] For example, the door body 120 has a mounting opening 121, and the mounting bracket 140 has a mounting part 141, wherein the mounting part 141 is a hollow structure, and the atomizing component 130 has a hook 135, which extends into and is fixed to the mounting part 141, and the mounting part 141 extends into and engages with the mounting opening 121, thereby completing the assembly of the atomizing component 130 and the door body 120.

[0110] Specifically, the atomizing component 130 includes a liquid storage box 131, which is used to store preservative liquid. When the preservative liquid inside is used up, or when the user wants to add preservative liquid, the liquid storage box 131 needs to be removed from the door 120 for replenishment. After replenishment, the liquid storage box 131 can be installed back onto the door 120, meaning that the liquid storage box 131 can be detached from the door 120.

[0111] In other embodiments, the user can open the liquid storage box 131 to replenish the liquid, and then close the liquid storage box 131 after replenishment. This means that the liquid storage box 131 is fixedly installed on the door 120, and the installation stability is high.

[0112] For example, the preservative liquid can be natural substances such as essential oils, chitosan, and nisin, which meet the requirements for consumption and are green and safe. The atomizing component 133 sprays out the preservative liquid into atomized particles and adheres to the surface of the food. The preservative in the atomized particles forms a preservative film layer on the surface of the food, which can effectively isolate the air and prevent the food from being secondary contaminated by bacteria in the air. At the same time, isolating the air can effectively inhibit the reproduction of bacteria, slow down the cell respiration and moisture loss inside the food, and play a role in preservation and anti-corrosion.

[0113] In other embodiments, the preservative solution can be tap water or a special electrolyte solution with added electrolytes, which is sprayed onto the food to preserve it.

[0114] Specifically, humidification is applied to the refrigeration room. This maintains a higher humidity level inside the refrigeration room, which is beneficial for the preservation and storage of items placed inside, especially vegetables and fruits.

[0115] It should be noted that, as a relatively closed cavity, the liquid storage box 131 can experience pressure differences between its interior and exterior during actual use due to temperature changes, liquid level changes, or external mechanical actions (such as opening and closing the door 120). Under the influence of this pressure difference, liquid will spontaneously seep out through the micropores on the atomizing element 133, causing unexpected overflow, which not only contaminates the equipment and wastes liquid, but also affects the user experience.

[0116] The liquid storage box 131 needs to ensure that the water inside the liquid storage box 131 does not leak out when it is stationary. If the liquid storage box 131 is completely sealed, water will continuously seep out from the micropores of the atomizing element 133 due to the imbalance of internal and external air pressure. Therefore, it is necessary to open a vent hole 1311 on the liquid storage box 131 to ensure the balance of internal and external air pressure through the vent hole 1311 and the airflow channel.

[0117] Figure 8 This is a first-view structural schematic diagram of the refrigerator inner cover assembly provided in an embodiment of this application. Figure 9 This is a structural schematic diagram of the refrigerator inner cover assembly provided in an embodiment of this application from a second perspective.

[0118] like Figures 6 to 9 As shown, in some alternative embodiments, the cover 132 has a cover surface 1321 facing the vent 1311;

[0119] The cover surface 1321 is provided with:

[0120] The groove 1322 extends to the edge of the cover 132 to form an airflow channel.

[0121] The above technical solution has the following advantages or beneficial effects: by integrating the airflow channel into the groove 1322 of the cover surface 1321 of the cover 132, the modularization and concealment of the air pressure balance function are realized. It is not only compact in structure and simple to assemble, but also achieves multiple effects of ventilation and leakage prevention.

[0122] The function is achieved by utilizing the structure of the cover 132 itself, simplifying the assembly process and reducing costs. The channel is cleverly hidden within the structure of the cover surface 1321, without affecting the product's appearance. The structure is simple, with no moving parts, resulting in a low failure rate.

[0123] When the cover 132 is closed on the box body 1315, one end of the groove 1322 is connected to the vent 1311, and the other end extends to the edge of the cover 132 and is connected to the outside atmosphere, thus forming an airflow channel.

[0124] In some embodiments, the groove 1322 has a larger opening size as it faces the edge of the cover 132.

[0125] In some alternative embodiments, the cover 132 is a plastic part; and / or,

[0126] The vent hole 1311 is a tapered hole.

[0127] The above technical solution has the following advantages or beneficial effects: Plastic parts are typically injection molded. This means that the groove 1322 on the mating surface 1321 can be injection molded in one step without subsequent machining. This reduces production costs, improves efficiency, and ensures precision and consistency.

[0128] As an optional embodiment, the cover 132 is injection molded, and one part of it has a cover surface 1321 opposite to the vent 1311. The cover surface 1321 is integrally formed with a groove 1322 by injection molding. When the cover 132 is closed on the box body 1315, one end of the groove 1322 communicates with the vent 1311, and the other end extends to the edge of the cover 132 and communicates with the outside atmosphere, thereby forming an airflow channel.

[0129] Specifically, the larger diameter end of the conical orifice faces the external environment, while the smaller diameter end communicates with the liquid chamber of the liquid storage box 131. This structure effectively utilizes surface tension to prevent liquid overflow, while its spacious external inlet greatly reduces the risk of complete blockage by dust and other contaminants.

[0130] When the liquid reservoir 131 is tilted, shaken, or overfilled, liquid may flow towards the vent 1311. The tapered vent (especially the structure with the smaller opening on the inside) utilizes the surface tension of the liquid. The liquid needs to overcome greater surface tension to seep out to the outside through the gradually narrowing channel (small opening), thus achieving a passive leak-proof function and realizing the ideal state of "ventilation but no liquid flow".

[0131] In addition, in injection molds, tapered cores (used for forming holes) are easier to demold and less prone to damage, which helps to improve mold life and production yield.

[0132] Continue to refer to Figures 6 to 9 In some optional embodiments, the liquid storage box 131 has a liquid injection section 1302, and a vent 1311 is located in the liquid injection section 1302;

[0133] The cover 132 includes a connecting portion 1323, the shape of which matches the shape of the liquid injection portion 1302, and the connecting portion 1323 covers the liquid injection portion 1302 so that the cover 132 is connected to the liquid storage box 131.

[0134] The above technical solution has the following advantages or beneficial effects: it ensures that when the cover 132 is closed, the groove 1322 on its cover surface 1321 can be precisely aligned with the vent hole 1311 on the liquid injection part 1302, thereby ensuring that the airflow channel can be reliably established every time and avoiding the risk of functional failure due to misalignment.

[0135] Since the injection section 1302 is a liquid channel, it is also the area most prone to pressure fluctuations due to changes in liquid level and operation. Directly setting a vent 1311 here allows for the fastest and most direct pressure regulation, providing the best response to instantaneous pressure changes.

[0136] In addition, the interlocking connection method usually has a clear sense of engagement, providing users with tactile feedback of successful operation, while ensuring the tightness of the connection and preventing it from coming loose during normal use.

[0137] In some alternative embodiments, the injection section 1302 is provided with an injection port 1312;

[0138] The cover 132 also includes a sealing part 1324 connected to the connecting part 1323. The sealing part 1324 protrudes toward the liquid storage box 131 and extends into the liquid injection port 1312.

[0139] The above technical solution has the following advantages or beneficial effects: the sealing part 1324 and the connecting part 1323 are integrated together on the same cover part 132. The sealing part 1324 is used to seal the injection port 1312 to meet the sealing requirements. The groove 1322 is connected to the vent hole 1311 to meet the air pressure balance requirements.

[0140] When the preservative in the storage box 131 is used up, or when the user wants to add preservative, the user opens the cover 132, causing the sealing part 1324 to come out from the injection port 1312. The user injects the preservative through the injection port 1312. After the injection is completed, the user closes the cover 132, and the sealing part 1324 seals the injection port 1312 again.

[0141] It should be noted that in some embodiments, the blocking part 1324 and the connecting part 1323 are connected in an integral manner. In other embodiments, the blocking part 1324 and the connecting part 1323 can also be connected in other ways. As long as the connection method can fix the blocking part 1324 and the connecting part 1323, the purpose of this embodiment can be achieved. Here, the connection method of the blocking part 1324 and the connecting part 1323 is not limited.

[0142] In some alternative embodiments, the sealing portion 1324 has a ring-shaped structure;

[0143] At least a portion of the outer periphery of the sealing portion 1324 is provided with a protrusion 1325.

[0144] The above technical solution has the following advantages or beneficial effects: the protrusion 1325 forms a line contact or narrow surface contact with the inner wall of the injection port 1312, providing the main sealing force and preventing a large amount of liquid leakage under normal conditions; the gap between the protrusion 1325 and the inner wall of the injection port 1312 forms a return channel, which allows the water overflowing from the vent hole 1311 during the opening and closing of the liquid storage box 131 to flow back, thereby solving the problem of water overflow from the liquid storage box 131.

[0145] The specific analysis is as follows: The sealing part 1324 is a hollow annular structure with at least one ring of protrusions 1325 (e.g., sealing ribs) on its outer peripheral wall. When the sealing part 1324 is inserted into the injection port 1312, the sealing protrusions 1325 make interference contact with the inner wall of the injection port 1312 to form a main seal; at the same time, a tiny gap channel can be formed between the multiple protrusions 1325 or between the protrusions 1325 and the inner wall of the injection port 1312. This gap channel design allows even a very small amount of liquid to overflow from the vent 1311 due to the opening and closing of the door 120, and can flow back smoothly into the liquid storage box 131 through this gap channel, without accumulating between the injection port 1312 and the cap 132 and causing overflow. In addition, the inner cavity of the annular structure also provides space for backflow.

[0146] Figure 10 This is a schematic diagram of the refrigerator lid provided in an embodiment of this application. Figure 11 for Figure 10 A magnified view of a portion of point I in the middle.

[0147] like Figures 6 to 11 As shown, in some optional embodiments, the injection section 1302 also has an annular groove 1313, which surrounds the outer periphery of the injection port 1312.

[0148] The injection section 1302 is provided with a notch 1314, and the annular groove 1313 is connected to the injection port 1312 through the notch 1314.

[0149] Among them, the annular groove 1313 is inclined relative to the liquid injection section 1302, and along the height direction of the box body 110, the groove wall height of the annular groove 1313 located at the notch 1314 is lower than the groove wall height of the annular groove 1313 located at other positions.

[0150] The above technical solution has the following advantages or beneficial effects: the bottom of the annular groove 1313 is an inclined plane, or the entire annular groove 1313 is inclined relative to the injection part 1302, and the notch 1314 is opened at the lowest position of the groove wall of the annular groove 1313. Utilizing gravity, liquid that may enter the annular groove 1313 can be automatically collected and guided back to the injection port 1312 through the notch 1314, preventing leakage.

[0151] In some embodiments, the tilt angle of the annular groove 1313 is not further limited here.

[0152] In some alternative embodiments, the liquid storage box 131 has an atomizing port 134 facing the refrigeration room;

[0153] The atomizing assembly 130 also includes an atomizing element 133, which is disposed in the liquid storage box 131 and is connected to the atomizing port 134.

[0154] The above technical solution has the following advantages or beneficial effects: after the atomizing component 133 atomizes the preservation liquid, it is sprayed into the refrigeration chamber through the atomizing port 134 to improve the preservation of food.

[0155] Specifically, the atomizing component 133 sprays out the preservative liquid into atomized particles and adheres to the surface of the food. The preservative in the atomized particles forms a preservative film layer on the surface of the food, which can effectively isolate the air and prevent the food from being secondary contaminated by bacteria in the air. At the same time, isolating the air can effectively inhibit the reproduction of bacteria, slow down the cell respiration and moisture loss inside the food, and play a role in preservation and anti-corrosion.

[0156] Specifically, atomized preservative solution helps maintain humidity levels in refrigerated rooms, preventing food from losing moisture due to excessive dryness, and is especially suitable for fruits and vegetables that require a high humidity environment. Furthermore, specific components in the preservative solution can absorb and neutralize odor molecules, maintaining a fresh smell in the refrigerated room and preventing cross-contamination of flavors between different foods.

[0157] Furthermore, users only need to add preservative solution periodically, eliminating the need for frequent manual adjustments. The atomizing component 130 automatically completes the atomization and dispersion process, simplifying the user's operation. By precisely controlling the atomization frequency and the amount of preservative solution, good preservation effects can be achieved while reducing energy consumption and improving the overall energy efficiency of the refrigerator 100.

[0158] In some embodiments, the atomizing element 133 is an ultrasonic atomizing plate. The ultrasonic atomizing plate can rapidly convert liquid into tiny droplets, forming a uniform atomization effect and improving the uniformity of the distribution of the preservative solution within the refrigeration room. It can also improve the utilization efficiency of the preservative solution, extend the shelf life of food, and maintain the freshness and nutrition of the food.

[0159] Specifically, the generated droplets are very fine, which can better cover and penetrate the surface of the food, enhance the effect of the preservative liquid, and improve the food's preservation performance.

[0160] Ultrasonic atomizing plates can be quickly started and stopped, providing instant atomization effects to meet users' dynamic needs for preservation environments. Their simple structure makes them easy to clean and maintain, reducing maintenance costs and time for users.

[0161] In some embodiments, the atomizing assembly 130 may further include an ultrasonic generator (not shown).

[0162] The ultrasonic generator is electrically connected to the atomizing element 133. The atomizing element 133 is used to acquire the electrical energy of the ultrasonic generator and convert it into sound wave energy. The sound wave energy causes the preservative liquid to form mist-like particles. After the ultrasonic generator generates a high-frequency current, it is transmitted to the atomizing element 133. The atomizing element 133 converts the electrical energy of the high-frequency current into sound waves of the same frequency. The sound waves act on the preservative liquid in the liquid storage box 131 and form tension waves on the surface of the preservative liquid. When the tension wave value reaches a predetermined value, the preservative liquid forms mist-like particles under the action of the tension wave. The sprayed mist-like particles adhere to the surface of the food to form a preservative film layer, thereby extending the shelf life of the food.

[0163] In some embodiments, the type of atomizing element 133 is not unique. For example, the atomizing element 133 can be a stainless steel atomizing plate, or it can be a ceramic atomizing plate.

[0164] Specifically, compared to stainless steel atomizing plates, ceramic atomizing plates exhibit a significant increase in capacitive reactance when their surface is lacking water. This causes the circuit to disconnect due to the mismatch between the impedance of the resistor and the capacitive reactance of the ceramic atomizing plate, thereby stopping the ceramic atomizing plate from oscillating. In this way, the ceramic atomizing plate can replace the water level detection device in the liquid storage box 131 to avoid damage caused by the vibration of the ceramic atomizing plate when water is lacking, thus improving the stability and reliability of the atomizing assembly 130.

[0165] Figure 12 This is a schematic diagram of the structure of the refrigerator box provided in an embodiment of this application.

[0166] like Figures 4 to 12 As shown, in some alternative embodiments, the liquid storage box 131 includes a box body 1315 having an opening;

[0167] The liquid storage box 131 also includes a box cover 1316, which covers the opening, and the box cover 1316 and the box body 1315 form a liquid storage cavity;

[0168] The liquid injection section 1302 is located on the box cover 1316.

[0169] The above technical solution has the following advantages or beneficial effects: the cover 1316 is placed on the opening of the box body 1315, and together with the box body 1315, they form a liquid storage cavity for storing liquid. The liquid injection part 1302 is placed on the cover 1316 for injecting liquid into the liquid storage cavity. The entire structural design is easy to manufacture and easy to assemble.

[0170] In some embodiments, the box body 1315 is container-shaped with an opening at the top. The box cover 1316 is placed over the opening and can be connected by means of snaps, threads or hinges, and together with the box body 1315, forms a closed liquid storage chamber (i.e., a liquid storage chamber).

[0171] In addition, the electrical connections within the liquid storage box 131 are separated from the liquid storage chamber, reducing the risk of electrical short circuits or malfunctions and improving the safety of the atomizing assembly 130.

[0172] In some embodiments, the atomizing component 130 further includes a controller that provides a high-frequency oscillation signal to the atomizing element 133.

[0173] In some alternative embodiments, the liquid storage box 131 also has a wire groove 1301 located outside the liquid storage cavity;

[0174] The liquid storage box 131 also includes a top cover 1317, which covers the box body 1315, and the top cover 1317 is located on the upper side of the box cover 1316;

[0175] Along the height direction Z of the box body 110, the projection of the box cover 1316 is located within the projection of the top cover 1317.

[0176] The above technical solution has the following advantages or beneficial effects: the design of the wire trough 1301 facilitates the wiring layout and is used to organize the power or signal lines of the atomizing component 133 (or other components that may be installed on the liquid storage box 131, such as the water level sensor), preventing the cables from being messy, tangled or accidentally pulled, thus improving the internal cleanliness, safety and reliability of the product.

[0177] It should be noted that the top cover 1317 is mainly used to protect the internal casing cover 1316, the liquid filling section 1302, and other structures from dust, impacts, or water splashes. It creates a smooth, aesthetically pleasing outer surface, concealing internal functional structures (such as the liquid filling port 1312), making the product appearance more concise and upscale. Furthermore, it prevents users from directly contacting any potential electrical connections 1323.

[0178] In some embodiments, the upper cover 1317 has an assembly hole 1319, the shape of which matches the liquid injection part 1302. The liquid injection part 1302 passes through the assembly hole 1319, and the cover 132 covers the liquid injection part 1302. The outer surface of the cover 132 is flush with the outer surface of the upper cover 1317, resulting in a high aesthetic appeal.

[0179] In some embodiments, the liquid storage box 131 further includes a top cover 1318, which is disposed on the box body 1315 and covers the top cover 1317 to shield the cover 132.

[0180] The refrigerator provided in this application includes a cabinet with a refrigeration compartment; a door movably connected to the cabinet and configured to open and close the refrigeration compartment; and an atomizing assembly disposed on the door. The atomizing assembly includes: a liquid storage box with a vent hole; and a cover covering the vent hole. The cover has an airflow channel communicating with the outside of the liquid storage box, and the airflow channel is connected to the vent hole.

[0181] By opening vents in the liquid storage box and connecting the vents with the airflow channel, the air pressure inside the liquid storage box and the external environment can be balanced in an instant, eliminating the driving force caused by the air pressure difference, thereby preventing liquid from leaking from the micropores of the atomizing component. Especially in scenarios where air pressure fluctuations are easily caused, such as when the door is opened and closed, the overflow prevention performance and reliability of the atomizing component are improved.
