Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, and in particular to a refrigerator. Background Technology

[0002] As living standards improve, people's demand for automated refrigerator doors is increasing. Refrigerators are equipped with automatic door opening and closing devices to enhance their intelligence and improve the user experience.

[0003] In the process of conceiving and implementing this utility model, the applicant discovered at least the following problems: the refrigerator compartment of existing refrigerators has a relatively large usable space, and existing users prefer to use the refrigerator compartment for short-term storage as the main way to preserve food. However, due to the frequent opening of the refrigerator door, the food preservation effect in the refrigerator compartment is poor.

[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 invention is to provide a refrigerator that extends the freshness and shelf life of food, while also achieving the required backflow prevention and sealing functions.

[0006] To achieve the above objectives, in a first aspect, the present invention provides a refrigerator, comprising:

[0007] The container has a refrigerated compartment;

[0008] The door is movably connected to the box body;

[0009] A food storage box, located inside the refrigerator compartment, includes:

[0010] Food storage container;

[0011] The lid is located on the body of the food storage box;

[0012] The atomizing component, located on the lid, includes:

[0013] A liquid storage box is used to store preservative solution;

[0014] The atomizing component is configured to atomize the preservative liquid in the liquid storage box to form a preservative water mist sprayed into the preservation box;

[0015] An anti-backflow component, located between the liquid reservoir and the atomizing element, includes:

[0016] The first anti-backflow component is provided in the liquid storage box, and the first anti-backflow component has a switchable open state and a closed state;

[0017] When the liquid storage box is installed onto the cover, the first anti-backflow component is configured to be in the open state to allow the liquid storage box and the atomizing component to communicate.

[0018] When the reservoir is removed from the cover, the first anti-backflow device is configured to be closed, thereby shutting down the reservoir and the atomizer.

[0019] The beneficial effects of this utility model are as follows: By setting up a liquid storage box and an atomizing component, the atomizing component transforms the preservative liquid in the liquid storage box into fine mist particles, which are evenly sprayed into the food preservation box. This effectively covers the surface of the food, slows down the evaporation and oxidation process, thereby extending the freshness and shelf life of the food, and increases the humidity of the food preservation box, thus improving the preservation capacity of the food preservation box, reducing food waste, and extending the storage time of the food, meeting users' high standards for food preservation. In addition, the anti-backflow component can effectively ensure the seal when the liquid storage box is removed and after the preservative liquid is added, preventing leakage. After the liquid storage box is installed, it can meet the atomization requirements of the atomizing component. The entire design is simple, easy to install, and saves time.

[0020] Based on the above technical solution, the present invention can be further improved as follows.

[0021] In some embodiments, the first anti-backflow element is an elastic membrane;

[0022] The first anti-backflow device includes multiple valves, which are in a closed state. When the multiple valves are subjected to external force, the multiple valves are configured to separate from each other, so that the first anti-backflow device is in an open state.

[0023] The above technical solution has the following advantages or beneficial effects: the first anti-backflow component is made of a soft elastic material, the flexibility of which allows it to deform under external force, thereby realizing the opening and closing function.

[0024] In some embodiments, when the multiple valves are in a closed state, the first anti-backflow element is hemispherical.

[0025] The above-mentioned technical solution has the following advantages or beneficial effects: the hemispherical valve provides a better sealing effect when closed; this shape ensures close contact between the valve edge and adjacent structures, reducing the possibility of leakage; and it generally has good mechanical properties, enabling uniform distribution of external pressure. This shape can improve the stability and durability of the anti-backflow component under high pressure conditions.

[0026] In some embodiments, the atomizing component further includes:

[0027] The liquid passage is connected to the atomizing element, and the anti-backflow component is located between the liquid storage box and the liquid passage.

[0028] The backflow prevention components also include:

[0029] The second anti-backflow component is located at the end of the liquid flow line. When the liquid storage box is installed on the cover, the second anti-backflow component provides external force to multiple valves so that the first anti-backflow component is in the open state.

[0030] The above technical solution offers the following advantages or beneficial effects: When the liquid storage box is installed onto the cover, the second anti-backflow component abuts against and passes through the gap of the first anti-backflow component, thereby opening it. This design allows liquid to flow into the liquid passage when needed, achieving atomization, while automatically closing when the liquid storage box is removed to prevent liquid leakage. Users can automatically control liquid flow simply by installing or removing the liquid storage box, without the need for manual operation of valves or other control devices. This improves the ease of use of the equipment and the user experience.

[0031] In some embodiments, the second anti-backflow component includes:

[0032] A push rod is located at the end of the liquid-conducting pipeline;

[0033] The abutment is located on the push rod and faces the first anti-backflow component.

[0034] The above technical solution has the following advantages or beneficial effects: when the liquid storage box is installed or removed, the relative position change of the push rod and the abutment automatically controls the opening and closing state of the first anti-backflow component. This reduces the user's operating steps and improves the convenience of the equipment and the user experience.

[0035] In some embodiments, the size of the abutment is larger than the size of the push rod.

[0036] The above technical solution has the following advantages or beneficial effects: Since the size of the abutment is larger than that of the push rod, it can provide a larger contact area when it contacts the first anti-backflow component, which can help the push rod to open the first anti-backflow component to a greater extent, so that the water storage box and the atomizing component can be better connected, and there will be no problem of poor flow of the preservation liquid.

[0037] In some embodiments, the abutment includes:

[0038] The abutment part is connected to the end of the push rod;

[0039] A connecting part is connected to the abutting part and surrounds the outer periphery of the abutting part.

[0040] The above technical solution has the following advantages or beneficial effects: by connecting the abutment part to the end of the push rod, a stable connection point is provided, ensuring that the push rod can effectively transmit force during operation.

[0041] In some embodiments, the second anti-backflow component further includes a mounting bracket, which is mounted on the end of the liquid passage, and the push rod is mounted on the mounting bracket.

[0042] The above technical solution has the following advantages or beneficial effects: the mounting bracket is installed at the end of the liquid-conducting pipeline, providing a stable support structure for the push rod. This design ensures that the push rod maintains correct axial alignment during operation, reducing operational instability caused by shaking or offset.

[0043] In some embodiments, the atomizing component further includes:

[0044] The junction box is located inside the box cover. The side wall of the junction box forms a liquid passage. The atomizing element is located at the rear end of the junction box facing the box body, and the liquid storage box is located at the front end of the junction box facing the box body.

[0045] The circuit board is located inside the junction box, on the side facing the liquid storage box, and the atomizing element is electrically connected to the circuit board.

[0046] The above technical solution has the following advantages or beneficial effects: the side wall of the junction box forms a liquid passage, integrating the atomizing element and the liquid storage box into one structure, reducing the use of external pipelines, making the entire atomizing assembly more compact, saving space, and improving the reliability and stability of the atomizing assembly.

[0047] Secondly, this utility model also provides a refrigerator, comprising:

[0048] Box;

[0049] The door is movably connected to the box body;

[0050] The food storage box is located inside the container;

[0051] The atomizing component, located inside the food storage box, includes:

[0052] A liquid storage box is used to store preservative solution;

[0053] The atomizing component is configured to atomize the preservative liquid in the liquid storage box to form a preservative water mist sprayed into the preservation box;

[0054] An anti-backflow component is located between the liquid reservoir and the atomizing element to allow the liquid reservoir and the atomizing element to be closed or connected.

[0055] The refrigerator provided by this utility model includes: a cabinet having a refrigerator compartment; a door movably connected to the cabinet; a preservation compartment disposed in the refrigerator compartment, the preservation compartment including: a preservation compartment body; a lid disposed on the preservation compartment body; an atomizing assembly disposed on the lid, the atomizing assembly including: a liquid storage box for storing preservation liquid; an atomizing element configured to atomize the preservation liquid in the liquid storage box to form a preservation mist sprayed into the preservation compartment; and an anti-backflow component located between the liquid storage box and the atomizing element, the anti-backflow component including: a first anti-backflow component disposed in the liquid storage box, and the first anti-backflow component having a switchable open state and a closed state; when the liquid storage box is installed on the lid, the first anti-backflow component is configured to be in the open state, so that the liquid storage box and the atomizing element are connected; when the liquid storage box is removed from the lid, the first anti-backflow component is configured to be in the closed state, so that the liquid storage box and the atomizing element are closed.

[0056] By incorporating a storage box and an atomizing component, the atomizing component transforms the preservative liquid in the storage box into fine mist particles, which are then evenly sprayed into the food storage compartment. This effectively covers the food surface, slowing down moisture evaporation and oxidation, thereby extending the freshness and shelf life of the food. It also increases the humidity within the storage compartment, enhancing its preservation capabilities, reducing food waste, and extending storage time, thus meeting users' high standards for food preservation. Furthermore, the anti-backflow component effectively ensures a tight seal when the storage box is removed and after adding preservative liquid, preventing leakage. After the storage box is installed, it meets the atomization requirements of the atomizing component. The entire design is simple, easy to install, and saves time. Attached Figure Description

[0085] like Figures 1 to 8 As shown, this embodiment of the utility model provides a refrigerator 100, comprising:

[0086] The cabinet 110 has a refrigerator compartment 111;

[0087] Door 120 is movably connected to box 110;

[0088] The food storage box 130 is located inside the refrigerator compartment 111. The food storage box 130 includes:

[0089] Refrigerated container 131;

[0090] The lid 132 is located on the refrigerated container body 131;

[0091] Atomizing component 140 is disposed on the cover 132. Atomizing component 140 includes:

[0092] Storage box 141 is used to store preservative solution;

[0093] The atomizing element 142 is configured to atomize the preservative liquid in the liquid storage box 141 to form a preservative water mist sprayed into the preservation box 131;

[0094] Backflow prevention component 149 is located between liquid storage box 141 and atomizing element 142. Backflow prevention component 149 includes:

[0095] The first anti-backflow component 1491 is provided in the liquid storage box 141, and the first anti-backflow component 1491 has a switchable open state and a closed state.

[0096] When the liquid storage box 141 is installed onto the cover 132, the first anti-backflow component 1491 is configured to be in the open state so that the liquid storage box 141 and the atomizing component 142 are connected.

[0097] When the liquid reservoir 141 is removed from the cover 132, the first anti-backflow component 1491 is configured to be closed, thereby closing the liquid reservoir 141 and the atomizer 142.

[0098] With the above-described configuration, the refrigerator 100 of this embodiment of the present invention, through the configuration of the liquid storage box 141 and the atomizing component 142, converts the preservative liquid in the liquid storage box 141 into fine mist particles, which are evenly sprayed into the preservation box 131. This effectively covers the surface of food, slows down the evaporation and oxidation process, thereby extending the freshness and shelf life of food, and increases the humidity of the preservation box 131, thereby improving the preservation capacity of the preservation box 131, reducing food waste, extending the storage time of food, and meeting users' high standards for food preservation. In addition, the anti-backflow component 149 can effectively ensure the seal when the liquid storage box 141 is removed and after the preservative liquid is added, preventing leakage. After the liquid storage box 141 is installed, it can meet the atomization requirements of the atomizing component 142. The entire design is simple, easy to install, and saves time.

[0099] It should be noted that the following provides a detailed explanation of each structure.

[0100] [Box 110]

[0101] refer to Figures 1 to 3The refrigerator 100 of this 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, they may be divided into a refrigerator compartment 111, a freezer compartment, or a variable temperature compartment, etc.

[0102] 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.

[0103] [Gate 120]

[0104] It should be noted that the door 120 can be connected to the cabinet 110 and is used to open or close the refrigeration compartment. One door 120 can be installed for each refrigeration compartment. Alternatively, two doors 120 can be installed for the same refrigeration compartment.

[0105] In some possible implementations of this utility model, the door 120 can be rotatably connected to the housing 110 about the height 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.

[0106] [Refrigerated Box 130]

[0107] It should be noted that the refrigerator 100 also includes a crisper compartment 130, which is pull-out and installed inside the refrigerator compartment 111. The crisper compartment 130 includes a crisper compartment body 131 and a lid 132 installed on the crisper compartment body 131. Specifically, the crisper compartment body 131 is pull-out and is used to hold food for easy access and storage by the user.

[0108] In some embodiments, the lid 132 can be detachably installed on the food storage box body 131 for easy maintenance and disassembly.

[0109] It should be noted that the food storage box 130 can be detachably installed inside the refrigerator compartment 111. In some embodiments, the detachable method can be, for example, snap-on installation or bolt installation, etc., which are not limited here.

[0110] In some embodiments of the present invention, the preservation box 130 is in a closed state relative to the refrigerator compartment 111. This does not limit the preservation box 130 to a sealed structure. The purpose is to prevent the preservative in the form of mist particles from spreading to other spaces in the refrigerator compartment 111, thereby effectively improving the spraying efficiency and effect on the food inside the preservation box 130.

[0111] [Atomizing Component 140]

[0112] It should be noted that the refrigerator 100 also includes an atomizing component 140, which is located on the lid 132. Specifically, the lid 132 has a hollow structure that can accommodate the atomizing component 140. The atomizing component 140 atomizes and preserves the food inside the preservation compartment 131.

[0113] Specifically, the atomizing component 140 includes a liquid storage box 141 for storing preservative liquid. When the preservative liquid inside is used up, or when the user wants to add preservative liquid, the liquid storage box 141 needs to be removed from the lid 132 for replenishment. After replenishment, the liquid storage box 141 can be installed back onto the lid 132, meaning that the liquid storage box 141 can be detached from the lid 132.

[0114] 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 142 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.

[0115] 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.

[0116] Specifically, the refrigerator 130 is humidified. This maintains a high humidity level inside the refrigerator 130, which is beneficial for the preservation and storage of items placed inside, especially vegetables and fruits.

[0117] In addition, the atomizing component 140 may also include an atomizing element 142, which 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.

[0118] Specifically, the atomized preservation liquid helps maintain the humidity level inside the preservation box 130, 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 preservation liquid can absorb and neutralize odor molecules, maintaining a fresh smell inside the preservation box 130 and preventing cross-contamination of flavors between different foods.

[0119] Furthermore, users only need to add preservative solution periodically, eliminating the need for frequent manual adjustments. The atomizing component 140 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.

[0120] In some embodiments, the atomizing component 140 is detachably installed inside the food storage box 130 to atomize and preserve the food inside the food storage box 130 through the atomizing element 142.

[0121] The removable liquid storage box 141 and atomizing component 142 facilitate regular cleaning and maintenance by users, ensuring the hygiene and long-term use of the atomizing component 140.

[0122] Figure 9 This is a schematic diagram showing the anti-backflow component in a refrigerator in a closed state, as provided in an embodiment of this utility model. Figure 10 This is a first-view structural diagram of the anti-backflow component in a refrigerator in the open state, as provided in an embodiment of this utility model. Figure 11 This is a second-view structural diagram of the anti-backflow component in a refrigerator provided in an embodiment of the present invention, with the component in the open state. Figure 12 This is a third-view structural diagram of the anti-backflow component in a refrigerator provided in an embodiment of the present invention, with the component in the open state.

[0123] like Figures 9 to 12 As shown, the atomizing assembly 140 may also include an anti-backflow member 149, which is disposed between the liquid storage box 141 and the atomizing element 142, and is used to keep the liquid storage box 141 and the atomizing element 142 in a connected state or a closed state.

[0124] When the liquid storage box 141 and the atomizing element 142 are in a connected state, it means that the preservative liquid in the liquid storage box 141 can enter the atomizing element 142, and the atomizing element 142 can atomize the preservative liquid and spray it onto the food in the preservation box 131.

[0125] When the liquid storage box 141 and the atomizing element 142 are in a closed state, it means that the liquid storage box 141 and the atomizing element 142 are not connected at this time. The liquid storage box 141 is in a closed state, which can prevent the preservation liquid inside from leaking out. The user can add preservation liquid to the liquid storage box 141. After the addition is completed, it is installed on the box cover 132.

[0126] Specifically, the anti-backflow component 149 includes a first anti-backflow element 1491, which has an open state and a closed state that can be switched between each other, thereby satisfying the connection between the liquid storage box 141 and the atomizing element 142, or the connection between the liquid storage box 141 and the atomizing element 142.

[0127] like Figures 9 to 12 As shown, in some embodiments, the first anti-backflow element 1491 is an elastic membrane;

[0128] The first anti-backflow component 1491 includes multiple valves, which are in a closed state. When the multiple valves are subjected to external force, the multiple valves are configured to separate from each other so that the first anti-backflow component 1491 is in an open state.

[0129] The above technical solution has the following advantages or beneficial effects: the first anti-backflow component 1491 is made of a soft elastic material. The flexibility of this material allows it to deform under external force, thereby realizing the opening and closing function.

[0130] Specifically, when no external force is applied, the valve remains closed, effectively preventing fluid from flowing backward. The design of the elastic membrane and valve provides good sealing performance and prevents leakage.

[0131] like Figure 9 As shown, in some embodiments, when multiple valves are in a closed state, the first anti-backflow element 1491 is hemispherical.

[0132] The above-mentioned technical solution has the following advantages or beneficial effects: the hemispherical valve provides a better sealing effect when closed; this shape ensures close contact between the valve edge and adjacent structures, reducing the possibility of leakage; and it generally has good mechanical properties, enabling uniform distribution of external pressure. This shape can improve the stability and durability of the anti-backflow component under high pressure conditions.

[0133] Furthermore, the hemispherical shape helps reduce turbulence and drag when the valve is closed, thereby improving the overall efficiency of the system. This streamlined design reduces energy loss, especially at high fluid flow velocities.

[0134] like Figures 1 to 12 As shown, in some embodiments, the atomizing component 140 further includes:

[0135] Liquid passage 143 is connected to atomizing element 142, and anti-backflow component 149 is located between liquid storage box 141 and liquid passage 143;

[0136] The backflow prevention component 149 also includes:

[0137] The second anti-backflow component 1492 is located at the end of the liquid passage 143. When the liquid storage box 141 is installed on the cover 132, the second anti-backflow component 1492 provides external force to multiple valves so that the first anti-backflow component 1491 is in the open state.

[0138] The above technical solution has the following advantages or beneficial effects: When the liquid storage box 141 is installed onto the cover 132, the second anti-backflow component 1492 abuts against and passes through the gap of the first anti-backflow component 1491, thereby opening it. This design allows liquid to flow into the liquid passage 143 when needed to achieve atomization, and automatically closes when the liquid storage box 141 is removed to prevent liquid leakage. Users can automatically control the liquid flow simply by installing or removing the liquid storage box 141, without the need for manual operation of valves or other control devices. This improves the ease of use of the equipment and the user experience.

[0139] Specifically, the design of the second anti-backflow component 1492 allows for precise control of the opening and closing of liquid flow. Through this effective anti-backflow design, liquid flows only when needed, reducing unnecessary waste. This not only saves resources but also lowers operating costs.

[0140] In some embodiments, the liquid passage 143 is provided to facilitate the connection between the liquid storage box 141 and the atomizing element 142. Considering that the liquid storage box 141 and the atomizing element 142 are located at different positions on the lid 132, the liquid passage 143 can be bent. This ensures that the preservative liquid can enter the atomizing element 142 while also reducing the flow path of the preservative liquid, thereby improving the compactness of the entire structure.

[0141] Continue to refer to Figures 9 to 12 In some embodiments, the second anti-backflow component 1492 includes:

[0142] Push rod 14921 is located at the end of liquid passage 143;

[0143] The abutment 14922 is located on the push rod 14921 and faces the first anti-backflow member 1491.

[0144] The above technical solution has the following advantages or beneficial effects: when the liquid storage box 141 is installed or removed, the relative position change of the push rod 14921 and the abutment 14922 automatically controls the opening and closing state of the first anti-backflow component 1491. This reduces the user's operating steps and improves the convenience of the equipment and the user experience.

[0145] Specifically, the push rod 14921 is located at the end of the liquid passage 143 and works in conjunction with the abutment 14922. When the liquid storage box 141 is installed in place, the push rod 14921 pushes the abutment 14922 into the gap of the first anti-backflow member 1491 through mechanical movement, precisely triggering its opening and ensuring the reliability and controllability of liquid flow.

[0146] When the liquid storage box 141 is not installed or is not in operation, the push rod 14921 and the abutment 14922 do not apply pressure to the first anti-backflow member 1491, ensuring that it remains in the closed state, thereby enhancing the system's sealing performance and preventing liquid leakage.

[0147] In some embodiments, the push rod 14921 and the abutment 14922 are typically made of durable materials capable of withstanding multiple operations without failure. This design improves the overall durability and stability of the system.

[0148] In some embodiments, the size of the abutment 14922 is larger than the size of the push rod 14921.

[0149] The above technical solution has the following advantages or beneficial effects: Since the size of the abutment 14922 is larger than that of the push rod 14921, it can provide a larger contact area when it contacts the first anti-backflow member 1491, which can help the push rod 14921 to open the first anti-backflow member 1491 to a greater extent, so that the water storage box and the atomizing member 142 can be better connected, and there will be no problem of poor flow of the preservation liquid.

[0150] In some embodiments, both the abutment 14922 and the push rod 14921 may be circular, with the diameter of the abutment 14922 being larger than the diameter of the push rod 14921.

[0151] Continue to refer to Figures 9 to 12 In some embodiments, the abutment member 14922 includes:

[0152] The abutment part is connected to the end of the push rod 14921;

[0153] A connecting part is connected to the abutting part and surrounds the outer periphery of the abutting part.

[0154] The above technical solution has the following advantages or beneficial effects: by connecting the abutment part to the end of the push rod 14921, a stable connection point is provided, ensuring that the push rod 14921 can effectively transmit force during operation.

[0155] In addition, the connecting portion surrounding the abutment portion may provide additional support and reinforcement, thereby improving the structural strength and durability of the entire component.

[0156] In some embodiments, the abutment 14922 has a wheel-shaped structure, which can provide a smoother movement path and assist the push rod 14921 in opening the first anti-backflow member 1491 to a greater extent.

[0157] In some embodiments, the mounting bracket 14923 may also be wheel-shaped, which can help to stably fix the push rod 14921 to the liquid inlet position of the junction box 144, ensuring that when the push rod 14921 is pushed to the first anti-backflow component 1491, the push rod 14921 will not break, and the first anti-backflow component 1491 can be stably pushed to the open state.

[0158] Continue to refer to Figures 9 to 12 In some embodiments, the second anti-backflow component 1492 further includes a mounting bracket 14923, which is mounted on the end of the liquid passage 143, and the push rod 14921 is mounted on the mounting bracket 14923.

[0159] The above technical solution has the following advantages or beneficial effects: the mounting bracket 14923 is installed at the end of the liquid-conducting pipeline 143, providing a stable support structure for the push rod 14921. This design ensures that the push rod 14921 maintains correct axial alignment during operation, reducing operational instability caused by shaking or offset.

[0160] In addition, the mounting bracket 14923 provides additional mechanical support for the push rod 14921, reducing deformation or damage to the push rod 14921 due to external forces, thereby improving the durability and service life of the system.

[0161] Continue to refer to Figures 1 to 12 In some embodiments, the atomizing component 140 further includes:

[0162] Junction box 144 is located inside box cover 132. Liquid passage 143 is formed on the side wall of junction box 144. Atomizing element 142 is located at the rear end of junction box 144 facing box 110. Liquid storage box 141 is located at the front end of junction box 144 facing box 110.

[0163] Circuit board 145 is located inside junction box 144. Circuit board 145 is located on the side facing liquid storage box 141. Atomizing element 142 is electrically connected to circuit board 145.

[0164] The above technical solution has the following advantages or beneficial effects: the side wall of the junction box 144 forms a liquid passage 143, which integrates the atomizing element 142 and the liquid storage box 141 into one structure, reduces the use of external pipelines, makes the entire atomizing assembly 140 more compact, saves space, and improves the reliability and stability of the atomizing assembly 140.

[0165] It should be noted that the liquid-conducting pipe 143 inside the junction box 144 ensures that the preservative liquid can be smoothly delivered from the storage box 141 to the atomizing element 142, which improves the atomization efficiency and preservation effect, provides better sealing performance, prevents leakage of the preservative liquid, and ensures the high efficiency and consistency of the atomization process.

[0166] In some embodiments, the second anti-backflow component 1492 is disposed at the liquid inlet of the junction box 144, and the first anti-backflow component 1491 is disposed at the liquid outlet of the storage box 141.

[0167] In addition, the electrical connections within the junction box 144 are separated from the liquid passage, reducing the risk of electrical short circuits or malfunctions and improving the safety of the atomizing assembly 140.

[0168] In some embodiments, the atomizing assembly 140 further includes a controller that provides a high-frequency oscillation signal to the atomizing element 142. The controller is installed in the junction box 144 of the atomizing assembly 140 and is electrically connected to the circuit board 145.

[0169] In some embodiments, the atomizing assembly 140 further includes a preservation lamp 147, which is obliquely disposed on the lid 132.

[0170] The Freshness Preservation Lamp 147 can emit light of a specific wavelength, which helps to inhibit the growth of microorganisms and slow down the oxidation process of food. The Freshness Preservation Lamp 147 with a specific spectrum can promote the biochemical reactions inside certain foods (such as vegetables and fruits), help maintain or enhance their nutritional value, and thus extend the shelf life of the food.

[0171] In some embodiments, the preservation lamp 147 is mounted on the junction box 144, which facilitates integration with other electrical components, simplifies circuit design and installation, and improves the overall reliability of the system.

[0172] In other embodiments, the freshness-preserving lamp 147 can be combined with an intelligent control system to automatically adjust the light intensity and time according to the type of food or user needs, thereby improving the intelligence level of the refrigerator 100.

[0173] In some embodiments, the preservation light 147 is installed on the side of the preservation box 131 near the door 120 to avoid the light source being too far ahead. This allows users to see the light source more intuitively and provides more comprehensive illumination of fruits and vegetables, resulting in better preservation.

[0174] In some embodiments, the atomizing element 142 is an ultrasonic atomizing sheet.

[0175] The above technical solution has the following advantages or beneficial effects: the ultrasonic atomizing plate can rapidly convert liquid into tiny droplets, forming a uniform atomization effect, which improves the uniformity of the distribution of the preservative liquid within the preservation box 130. It also improves the utilization efficiency of the preservative liquid, extends the preservation time of food, and maintains the freshness and nutrition of the food.

[0176] 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.

[0177] 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.

[0178] In some embodiments, the atomizing assembly 140 may further include an ultrasonic generator (not shown).

[0179] The ultrasonic generator is electrically connected to the atomizing element 142. The atomizing element 142 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 142. The atomizing element 142 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 141 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.

[0180] In some embodiments, the type of atomizing element 142 is not unique. For example, the atomizing element 142 can be a stainless steel atomizing plate, or it can be a ceramic atomizing plate.

[0181] 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 141 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 140.

[0182] The refrigerator provided in this embodiment of the present invention includes: a cabinet having a refrigerator compartment; a door movably connected to the cabinet; a preservation compartment disposed in the refrigerator compartment, the preservation compartment including: a preservation compartment body; a lid disposed on the preservation compartment body; an atomizing assembly disposed on the lid, the atomizing assembly including: a liquid storage box for storing preservation liquid; an atomizing element configured to atomize the preservation liquid in the liquid storage box to form a preservation mist sprayed into the preservation compartment body; and an anti-backflow component located between the liquid storage box and the atomizing element, the anti-backflow component including: a first anti-backflow component disposed in the liquid storage box, and the first anti-backflow component having a switchable open state and a closed state; when the liquid storage box is installed on the lid, the first anti-backflow component is configured to be in the open state, so that the liquid storage box and the atomizing element are connected; when the liquid storage box is removed from the lid, the first anti-backflow component is configured to be in the closed state, so that the liquid storage box and the atomizing element are closed.

[0183] By incorporating a storage box and an atomizing component, the atomizing component transforms the preservative liquid in the storage box into fine mist particles, which are then evenly sprayed into the food storage compartment. This effectively covers the food surface, slowing down moisture evaporation and oxidation, thereby extending the freshness and shelf life of the food. It also increases the humidity within the storage compartment, enhancing its preservation capabilities, reducing food waste, and extending storage time, thus meeting users' high standards for food preservation. Furthermore, the anti-backflow component effectively ensures a tight seal when the storage box is removed and after adding preservative liquid, preventing leakage. After the storage box is installed, it meets the atomization requirements of the atomizing component. The entire design is simple, easy to install, and saves time.

[0184] In addition, such as Figures 1 to 12 As shown, this utility model embodiment also provides a refrigerator 100, including: a cabinet 110; a door 120 movably connected to the cabinet 110; a fresh-keeping compartment 130 disposed inside the cabinet 110; and an atomizing assembly 140 disposed inside the fresh-keeping compartment 130. The atomizing assembly 140 includes: a liquid storage box 141 for storing fresh-keeping liquid; an atomizing element 142 configured to atomize the fresh-keeping liquid in the liquid storage box 141 to form a fresh-keeping water mist sprayed into the fresh-keeping compartment 130; and an anti-backflow member 149 located between the liquid storage box 141 and the atomizing element 142 to close or connect the liquid storage box 141 and the atomizing element 142.

[0185] The refrigerator provided in this embodiment of the utility model, through the setting of a liquid storage box and an atomizing component, transforms the preservative liquid in the liquid storage box into fine mist particles, which are evenly sprayed into the preservation box. This effectively covers the surface of food, slows down the evaporation and oxidation process, thereby extending the freshness and shelf life of food, and increases the humidity of the preservation box, improving the preservation capacity of the preservation box, reducing food waste, and extending the storage time of food, thus meeting users' high standards for food preservation. In addition, the anti-backflow component can effectively ensure the seal when the liquid storage box is removed and after the preservative liquid is added, preventing leakage. After the liquid storage box is installed, it can meet the atomization requirements of the atomizing component. The entire design is simple, easy to install, and saves time.
