[0002] With the fast pace of life and improved living standards, fresh-cut fruits and vegetables have become increasingly popular. Fruit shops and individuals at home peel and cut various fruits, then wrap them in plastic bags or plastic film and store them in the refrigerator for later consumption.

[0003] Fresh-cut fruits and vegetables are prone to browning during processing due to cell damage; for example, fresh-cut apples, potatoes, and lotus roots turn brown and darken in color. Furthermore, improper storage of fresh-cut fruits and vegetables can lead to spoilage due to microbial growth. Therefore, controlling browning and inhibiting microbial growth are hot topics in research on the storage of fresh-cut fruits and vegetables.

[0004] However, existing refrigerators do not have a dedicated area for storing fresh-cut fruits and vegetables, forcing users to place them in the refrigerator compartment. This makes fresh-cut fruits and vegetables prone to cross-contamination of flavors with other ingredients and fruits and vegetables, thus affecting their freshness. Utility Model Content

Detailed Implementation

[0041] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0042] In the description of this utility model, it should be understood that, in the embodiments shown in the accompanying drawings, the indications of direction or positional relationships (such as up, down, left, right, front, and back, etc.) are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the accompanying drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0044] Freshly cut fruits and vegetables are prone to browning during processing due to cell damage. For example, freshly cut apples, potatoes, and lotus roots turn brown and darken in color.

[0045] Enzymatic browning is the primary cause of browning in fresh-cut fruits and vegetables. Under the catalysis of polyphenol oxidase, phenolic compounds are oxidized into ortho-quinones, which further oxidize and condense to form brown products. Currently, methods to inhibit enzyme activity mainly include heating, chemical methods (controlling acidity, antioxidants, sodium bisulfite), microwave methods, and modified atmosphere packaging (controlling oxygen concentration). Heating and microwave methods can damage the nutritional structure and natural flavor of the ingredients; adding chemicals has a good anti-browning effect, but it has drawbacks such as drug residues and damage to the quality of fruits and vegetables; modified atmosphere packaging is difficult to implement at home.

[0046] Meanwhile, improper storage of fresh-cut fruits and vegetables can lead to spoilage due to microorganisms. Furthermore, existing refrigerators lack a dedicated area for fresh-cut fruits and vegetables, forcing users to place them in the refrigerator compartment. This makes them susceptible to cross-contamination of odors with other foods and vegetables, thus affecting their freshness. Therefore, controlling browning and inhibiting microbial growth are hot topics in fresh-cut fruit and vegetable storage research. This paper proposes a refrigerator to address these issues.

[0047] Figure 1 This is a schematic diagram of the refrigerator door, storage device, and lid according to an embodiment of the present utility model. Figure 2 yes Figure 1 A front view diagram of the refrigerator door, storage compartments, and lid. Figure 3 yes Figure 1 A perspective view of the cabinet door and storage device. In this embodiment, using... Figure 2 The vertical direction in the text refers to the refrigerator's vertical direction.

[0048] The scheme is further illustrated by the following examples:

[0049] Please see Figure 1 , Figure 2 and Figure 3 The refrigerator of this embodiment may include a cabinet, a door 2, a storage device 10, a lid 20, and an ultrasonic component 30.

[0050] The cabinet may include a refrigeration compartment with an opening on one side. A door 2 is mounted on the cabinet for opening and closing the refrigeration compartment. A storage device 10 is mounted on the door 2, located on the side of the door facing the refrigeration compartment. The storage device 10 may include a mounting base 11, a hinge 12, and a storage box 13. The storage box 13 has a receiving cavity 130 with one open side for placing food. A lid 20 can close onto the side opening of the storage box 13, allowing food to be contained within the receiving cavity 130, thus isolating the food. An ultrasonic component 30 is mounted on the storage device 10 to sterilize the food within the receiving cavity 130 using ultrasonic waves, thereby preserving the food.

[0051] In this embodiment, a refrigeration compartment with an opening on one side is formed on the cabinet. The refrigeration compartment can form a low-temperature space. Specifically, the refrigeration compartment can be the refrigerator compartment or the freezer compartment of the refrigerator, so that the refrigeration compartment can be used to store fruits, vegetables, raw meat, and other food or supplies, and to keep the food fresh, prevent the food from spoiling, and extend the storage time of the food.

[0052] The door 2 can be located at the opening of the refrigeration compartment for opening and closing the refrigeration compartment. That is, the door 2 is hinged to the cabinet and located at the opening of the refrigeration compartment, and can rotate relative to the cabinet to open or close the refrigeration compartment.

[0053] The storage device 10 can be installed on the side of the cabinet door 2 facing the refrigeration room, so that after the cabinet door 2 is closed on the cabinet, the storage device 10 can be housed in the refrigeration room, thereby allowing the food placed in the storage box 13 to be located in the refrigeration room.

[0054] like Figure 1 and Figure 3 As shown, the mounting base 11 is detachably connected to the door 2.

[0055] In this embodiment, the mounting base 11 can be configured as a plate-like structure, allowing it to be connected to the door 2. Alternatively, the mounting base 11 can be configured as a strip-like or block-like structure, enabling the storage device 10 to be connected to the door 2 via the mounting base 11.

[0056] In addition, a latching assembly 40 may be provided on the door 2. The latching assembly 40 can be used to latch the mounting base 11, allowing the mounting base 11 to be detachably connected to the door 2, thereby facilitating the connection of the storage device 10 to the door 2 for convenient use. Alternatively, it can facilitate the removal of the storage device 10 from the door 2, preventing the storage device 10 from interfering with or disturbing the refrigeration compartment when not in use, thus improving the refrigerator's user experience.

[0057] The latching assembly 40 may be provided with two latching parts, and the two latching parts are spaced apart on the door 2 to connect to the side of the mounting base 11 facing the door 2, or to the opposite sides of the mounting base 11, so that the mounting base 11 can be stably connected to the door 2 and avoid the mounting base 11 from shaking relative to the door 2.

[0058] Specifically, the fastener may be provided with a snap-fit ​​groove. The snap-fit ​​groove can snap onto the side of the mounting base 11, so that the mounting base 11 is connected to the door 2.

[0059] In some other embodiments, the fastener can be configured as a hook, and the mounting base 11 can be provided with a hook or a hook hole so that the hook can cooperate with the hook or the hook hole so that the mounting base 11 can be detachably connected to the door 2.

[0060] Figure 4 yes Figure 1 A schematic diagram of the storage box of the storage device in the unfolded position. Figure 5 yes Figure 1 This is a diagram showing the storage box of the storage device in its storage position.

[0061] See Figure 3 , Figure 4 and Figure 5 The storage box 13 can be connected to the mounting base 11 via the hinge 12, so that the storage box 13 can rotate relative to the mounting base 11 and switch between the unfolded position and the storage position.

[0062] Specifically, the hinge 12 can be configured as a hinge or a hinge structure, so that the storage box 13 can rotate relative to the mounting base 11 via the hinge 12.

[0063] It should be noted that a limiting structure can also be provided on the hinge 12 so that after the storage box 13 is rotated to the unfolded position, the limiting structure can restrict the rotation of the storage box 13 relative to the mounting base 11, thereby allowing the storage box 13 to be limited to the unfolded position.

[0064] Of course, the limiting structure can also be directly connected between the storage box 13 and the mounting base 11 or the door 2, so that after the storage box 13 is rotated to the unfolded position, the limiting structure can restrict the storage box 13 from rotating relative to the mounting base 11 or the door 2, thereby allowing the storage box 13 to be limited to the unfolded position.

[0065] like Figure 4 As shown, when in the unfolded position, the storage box 13 extends horizontally, allowing it to be used to place food or other items. In other words, the storage box 13 can form a separate storage area in the refrigerator compartment, allowing fresh-cut fruits and vegetables to be placed in this separate area for easy access. This avoids mixing fresh-cut fruits and vegetables with other foods or items in the refrigerator compartment and prevents them from absorbing odors from other ingredients in the refrigerator, thus avoiding unpleasant taste.

[0066] like Figure 5As shown, when in its storage position, the storage box 13 extends vertically and is positioned close to or against the side of the refrigerator door 2 facing the refrigeration compartment. This prevents the storage box 13 from extending too far into the refrigeration compartment when horizontal, thus avoiding interference or damage to items. Therefore, when in its storage position, the storage box 13 minimizes its impact on the user's use of the refrigeration compartment, effectively utilizing the space within the compartment and improving the user's refrigerator experience.

[0067] Figure 6 yes Figure 1 A schematic diagram of the storage box of the storage device. Figure 7 yes Figure 1 A schematic diagram of the internal structure of the storage box of the storage device.

[0068] See Figure 6 and Figure 7 The storage box 13 may include a medium layer 131 and two stainless steel layers 132.

[0069] Two stainless steel layers 132 are located on opposite sides of the medium layer 131 to form the overall plate-like structure of the storage box 13. Specifically, of the two stainless steel layers 132, the stainless steel layer 132 used for placing or contacting fresh-cut fruits and vegetables can be defined as the support layer 133, that is, the stainless steel layer 132 constituting the inner wall of the accommodating cavity 130 is defined as the support layer 133. The other stainless steel layer 132 can be defined as the mounting layer 134, and the mounting layer 134 can be used to mount the ultrasonic component 30. That is, in this embodiment, the ultrasonic component 30 is mounted on the storage box 13, specifically, the ultrasonic component 30 is located at the bottom of the storage box 13, so that the ultrasonic component 30 can sterilize the food in the accommodating cavity 130 through ultrasonic waves, thereby preserving the food.

[0070] In some other embodiments, the stainless steel layer 132 may also be a plate layer of other materials, such as a rigid plastic layer or a glass plate layer, for placing food or mounting the ultrasonic component 30.

[0071] In addition, the medium layer 131 can be set as a material layer that facilitates ultrasonic wave transmission, thereby avoiding the loss of ultrasonic wave power during transmission, which would affect the sterilization and preservation effect.

[0072] In this embodiment, the ultrasonic component 30 may include a plurality of ultrasonic transducers 31. The plurality of ultrasonic transducers 31 are spaced apart on the storage box 13, that is, the plurality of ultrasonic transducers 31 are spaced apart on the stainless steel layer 132, so that the plurality of ultrasonic transducers 31 emit ultrasonic waves simultaneously and transmit them evenly to the food on the support layer 133, thereby sterilizing and preserving the food, and inhibiting browning of fresh-cut fruits and vegetables.

[0073] Specifically, during the generation and transmission of ultrasound, cavitation occurs, forming cavitation bubbles. When these bubbles burst, they generate extremely high temperatures and pressures. The released energy alters the spatial conformation of enzyme molecules, thereby deactivating enzyme activity and inhibiting browning in fresh-cut fruits and vegetables.

[0074] In this embodiment, the power output of the ultrasonic component 30 can be adjusted so that the ultrasonic component 30 can output power of 0-150W as needed to meet the needs of different ingredients or foods for preservation and prevention of browning.

[0075] Figure 8 yes Figure 1 A front view of the refrigerator lid. Figure 9 yes Figure 1 A bottom view of the refrigerator lid. Figure 10 yes Figure 1 Another illustration of the refrigerator lid.

[0076] See Figure 8 The lid 20 may be provided with a snap-fit ​​part 21 so that the lid 20 can be closed on the open side of the storage box 13 through the snap-fit ​​part 21.

[0077] Specifically, after the lid 20 is placed on the storage box 13, it can seal the accommodating cavity 130, so that the food in the accommodating cavity 130 can be isolated from the external environment of the storage box 13 and the lid 20, thereby ensuring that the food is in an independent space and preventing the food on the storage box 13 from absorbing the odors of other foods in the refrigeration room.

[0078] In this embodiment, the shape of the lid 20 can be adapted to the shape of the storage box 13 so that the lid 20 can be closed on the storage box 13.

[0079] Specifically, when in the unfolded position, the storage box 13 can extend horizontally, allowing it to be used to place food. At this time, the lid 20 can also be placed on the storage box 13, and the latching part 21 of the lid 20 engages with the open side of the storage box 13, i.e., the opening of the accommodating cavity 130. This allows the lid 20 to engage with the storage box 13, forming a sealed space in the accommodating cavity 130. This prevents the food in the storage box 13 from absorbing odors from other foods, ensuring the freshness of the food in the storage box 13.

[0080] When in the storage position, the storage box 13 extends vertically. At this time, the latching part 21 of the lid 20 engages with the opening of the accommodating cavity 130, so that the lid 20 is connected to the storage box 13, that is, the lid 20 also extends vertically. That is, during the process of the storage box 13 rotating from the unfolded position to the storage position, the lid 20 remains closed on the storage box 13.

[0081] Of course, in some other embodiments, when the storage box 13 is in the storage position, or during the process of rotating the storage box 13 from the unfolded position to the storage position, it is necessary to remove the lid 20 from the storage box 13 to prevent the lid 20 from falling off during the rotation of the storage box 13.

[0082] In this embodiment, the lid 20 can be set as a transparent lid, so that the user can intuitively observe the food in the accommodating cavity 130, thereby facilitating the user's use and improving the user experience.

[0083] Specifically, the lid 20 can be made of transparent acrylic sheet, other transparent plastic, or transparent glass.

[0084] The lid 20 can also be configured as a soundproof cover to reduce the noise generated by the vibration of the ultrasonic component 30 on the storage box 13, thereby improving the user experience. Simultaneously, a sealing strip can be provided on the side of the lid 20 facing the storage box 13, i.e., a sealing strip can be provided on the snap-fit ​​part 21, allowing the lid 20 to be sealed to the storage box 13 via the sealing strip, ensuring a sealed connection between the lid 20 and the storage box 13, and thus ensuring that the accommodating cavity 130 can form a sealed chamber.

[0085] See Figure 9 and Figure 10 The refrigerator may also include a germicidal lamp 22.

[0086] In this embodiment, the lid 20 may also be provided with a cavity 23, that is, the snap-fit ​​portion 21 is recessed inward to form a cavity 23, so that after the lid 20 is snapped onto the storage box 13, the cavity 23 can connect to the accommodating cavity 130, thereby expanding the storage space.

[0087] The germicidal lamp 22 is installed on the lid 20 and located in the chamber 23, so that the germicidal lamp 22 can emit light for sterilization into the accommodating cavity 130, thereby working together with the ultrasonic component 30 to sterilize, ensuring the sterilization effect in the accommodating cavity 130, and thus improving the preservation and browning prevention of food in the accommodating cavity 130.

[0088] In this embodiment, the germicidal lamp 22 can emit light with a wavelength of 400nm-420nm, that is, the germicidal lamp 22 can emit purple light or blue light for sterilization, thereby achieving the effect of preservation.

[0089] Furthermore, two germicidal lamps 22 can be provided so that the light emitted by the two germicidal lamps 22 can be evenly distributed within the chamber 23, thereby avoiding blind spots and improving the sterilization effect. Specifically, in this embodiment, both germicidal lamps 22 are 1-watt blue light lamps.

[0090] It should be noted that both the ultrasonic component 30 and the germicidal lamp 22 can be electrically connected to the control module of the door 2 to supply power to the ultrasonic component 30 and the germicidal lamp 22, and to allow users to control the operation or shutdown of the ultrasonic component 30 and the germicidal lamp 22 through the control module on the door 2.

[0091] Of course, in some other embodiments, the ultrasonic component 30 and the germicidal lamp 22 may also be powered by separate power modules to ensure that the ultrasonic component 30 and the germicidal lamp 22 can work normally.

[0092] In this embodiment, the output power of the ultrasonic component 30 can be selected according to the type or characteristics of the food. For example, when the food is watermelon, strawberry, or other ingredients that are prone to water loss or breakage, the ultrasonic component 30 adopts a low-power mode with a frequency of 20kHz and a power of 40W. The ultrasonic component 30 operates for 8 seconds each time, cycles once every 50 minutes, and repeats 10 times. When the food is peach, tomato, cherry, banana, or other similar ingredients, the ultrasonic component 30 adopts a power mode with a frequency of 30kHz and a power of 70W. The ultrasonic component 30 operates for 15 seconds each time, cycles once every 40 minutes, and repeats 20 times. When the food is plum, apple, pear, or other hard fruits that are not prone to water loss, or fresh-cut potatoes, lotus root slices, or other ingredients that are prone to browning, the ultrasonic component 30 adopts a power mode with a frequency of 30kHz and a power of 150W. The ultrasonic component 30 operates for 20 seconds each time, cycles once every 40 minutes, and repeats 30 times.

[0093] In addition, when the ultrasonic component 30 is turned on, the germicidal lamp 22 is also turned on simultaneously, and the germicidal lamp 22 is turned on for 5 seconds each time, cycling once every 1 hour. At the same time, the germicidal lamp 22 automatically turns off when the refrigerator door is opened to avoid the light emitted by the germicidal lamp 22 causing harm to the human body.

[0094] In summary, the storage device 10 is detachably connected to the door 2 via the mounting base 11 and is located inside the refrigeration compartment, facilitating its installation and removal and enabling its use in different refrigeration compartments. Simultaneously, the storage box 13 has an open-sided receiving cavity 130 and is connected to the mounting base 11 via a hinge 12, allowing it to rotate relative to the mounting base 11 and switch between an unfolded and a retracted position. In the unfolded position, the storage box 13 extends horizontally, allowing food to be placed in the receiving cavity 130, thus facilitating its use. In the retracted position, the storage box 13 extends vertically and fits against the door 2, preventing it from affecting the space inside the refrigeration compartment and facilitating its storage, thus avoiding interference with the refrigerator's daily operation. Meanwhile, when the storage box 13 is in the unfolded position, the open side of the lid 20 can close onto the storage box 13, allowing food to be contained within the containing cavity 130, thus creating an isolated space and preventing cross-contamination of odors between the food in the refrigeration room and the food in the containing cavity 130. An ultrasonic component 30 is installed on the storage box 13 to sterilize the food in the containing cavity 130 using ultrasonic waves, thereby preserving the food.

[0095] In addition, a germicidal lamp 22 is provided on the lid 20, which can sterilize the cavity 130. The germicidal lamp 22 can work with the ultrasonic component 30 to sterilize the food, thereby preventing browning and ensuring the freshness of the food.

[0096] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
