[0040] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the embodiments of the present invention will be more comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, many specific details are provided to provide a full understanding of the implementation of the embodiments of the present invention.

[0041] The fresh-keeping area provides a more stable and suitable storage environment for food by controlling the temperature and humidity fluctuations in the storage space, thereby maximizing the taste and flavor of the food. In terms of the sealing structure of the fresh-keeping area, the existing technology usually achieves sealing by fixing the sealing cover relative to the drawer. This design can ensure that the sealing cover fits tightly against the edge of the drawer when the drawer is closed, effectively preventing cold air leakage and maintaining stable temperature and humidity in the fresh-keeping area. However, when the drawer needs to be pulled out to take out the food, the user needs to further open the sealing cover, which is inconvenient to take out the food.

[0042] In order to solve the above problems, the first aspect of the embodiment of the present application provides a sealing structure for a fresh-keeping area, referring to Figure 1 and Figure 2 As shown, it includes: an air duct cover 20, a fruit and vegetable box cover 30 and a fresh-keeping area; the fresh-keeping area in this embodiment is mainly composed of a drawer mask 51 and a drawer bucket 52, wherein the drawer mask 51 is designed as a double-layer structure to enhance its heat preservation performance, and the drawer bucket 52 is placed in the inner layer of the drawer mask 51 for storing food.

[0043] The fruit and vegetable box cover 30 is divided into two parts: a fruit and vegetable cover 31 and a sealing cover 32. The sealing cover 32 is located below the fruit and vegetable cover 31, and a sliding connection between the two is achieved through a specific track structure. This design allows the fruit and vegetable cover 31 to slide freely on the sealing cover 32 without having to completely open the sealing cover 32 as in the traditional structure.

[0044] The side of the sealing cover plate 32 close to the fresh-keeping area is designed as an inclined surface, and the inclined surface structure can closely fit the top edge of the drawer 52 to form an effective sealing effect. At the same time, the inclined surface design also allows the sealing cover plate 32 to slide smoothly when the drawer 52 is opened, reducing friction and resistance.

[0045] As the part that the user directly contacts, the fruit and vegetable cover 31 not only provides a convenient passage for taking and placing ingredients, but also allows the user to easily access the ingredients without fully opening the sealing cover 32 through its sliding connection design. The main function of the sealing cover 32 is to maintain the temperature and humidity stability in the fresh-keeping area. Its inclined design fits tightly with the top edge of the drawer 52, effectively preventing cold air leakage, thereby ensuring the freshness and taste of the ingredients. At the same time, the track structure allows the sealing cover 32 to move flexibly with the sliding of the fruit and vegetable cover 31, maintaining the sealing effect while improving the convenience of use.

[0046] The drawer cover 51 and the drawer compartment 52 are the main structures of the fresh-keeping area. The double-layer design of the drawer cover 51 enhances the heat preservation performance, while the drawer compartment 52 provides sufficient storage space. The two work together to provide a stable and suitable storage environment for food.

[0047] In actual application, the user only needs to pull out the fresh-keeping area, and the drawer 52 and the sealing cover 32 are matched with each other in an inclined plane. When the fresh-keeping area is pulled out, the gap between the sealing cover 32 and the drawer 52 gradually expands and the seal is released; when the fresh-keeping area is pushed back, the gap between the sealing cover 32 and the drawer 52 gradually decreases until it is sealed. The whole process is simple and fast, and there is no need to open and close the sealing cover 32 cumbersomely, which greatly improves the convenience and efficiency of use. At the same time, the inclined design of the sealing cover 32 and the close fit of the drawer 52 also ensure the stability of temperature and humidity in the fresh-keeping area, providing the best storage environment for food.

[0048] The air duct cover plate 20 includes an air nozzle 22, which is connected to the drawer cover 51. Cold air is blown in by the air nozzle 22, which can be used to efficiently cool the sealed fresh-keeping area to achieve a fresh-keeping effect in the fresh-keeping area.

[0049] The present application effectively solves the problem of inconvenience in taking and placing food in the traditional fresh-keeping area sealing structure by designing the fruit and vegetable box cover 30 as a sliding structure and combining it with the inclined surface design of the sealing cover 32. The user only needs to pull out the fresh-keeping area without completely opening the sealing cover 32, thereby greatly improving the convenience and efficiency of use.

[0050] In some embodiments of the present application, the drawer cover 51 is provided with an air inlet 511 and a first air outlet 512, a second air outlet 521 is provided at the bottom of the drawer 52, and the air nozzle 22 is aligned with the air inlet 511 to ensure effective input of cold air.

[0051] The air inlet 511 provided on the drawer cover 51 is used to receive the cold air input from the air nozzle 22 of the air duct cover 20, and the first air outlet 512 is located at an appropriate position of the drawer cover 51 to send the cold air to the area around the drawer cover 51 to maintain the temperature balance in the fresh-keeping area. The second air outlet 521 is provided at the bottom of the drawer 52. It ensures that the cold air forms a complete air path around the drawer cover 51, and the cold air can evenly cover the food in the drawer 52 to maintain the freshness and taste of the food.

[0052] Specifically, the air duct cover 20, the fruit and vegetable box cover 3, and the fresh-keeping area cooperate with each other to form an air path. Cold air enters the fresh-keeping area from the air nozzle 22, passes through the drawer mask 51 along the air inlet 511 and the first air outlet 512 set on the drawer mask 51 in sequence, and leaves the fresh-keeping area from the second air outlet 521 set at the bottom of the drawer bucket 52.

[0053] Cold air is blown in by the air nozzle 22 provided on the air duct cover 20, and leaves by the second air outlet 521 provided on the drawer 52, so as to form an air path, which can not only efficiently cool the sealed fresh-keeping area, but also effectively avoid gas exchange between the sealed fresh-keeping area and the refrigerated space, thereby increasing the humidity of the fresh-keeping area and improving the fresh-keeping effect.

[0054] In this embodiment, the design of the air duct cover 20 and its air nozzle 22 enables the cold air to be accurately delivered to the fresh-keeping area, avoiding waste and ineffective circulation of the cold air. The air inlet 511, the first air outlet 512 of the drawer cover 51 and the second air outlet 521 of the drawer 52 work together to ensure a more uniform temperature distribution in the fresh-keeping area, avoiding adverse effects of temperature fluctuations on the food. By accurately controlling the input and output of the cold air, this solution ensures that the food can obtain the best storage environment in the fresh-keeping area.

[0055] In some embodiments of the present application, the fresh-keeping area also includes: a uniform cold plate 53, which is located at the bottom of the inner cavity of the drawer 52; the uniform cold plate 53 and the bottom surface of the inner cavity of the drawer 52 have a certain distance, and the distance forms an interlayer channel, which is connected to the second air outlet 521.

[0056] As one of the core components in the fresh-keeping area, the main function of the cold plate 53 is to evenly distribute cold air to ensure that the food in the drawer 52 can be evenly cooled. Taking into account the natural diffusion characteristics of cold air during the flow process, through a reasonable structural layout, the cold air can flow evenly along the surface of the cold plate 53.

[0057] In this embodiment, the interlayer channel formed by the distance between the cold plate 53 and the bottom of the inner cavity of the drawer 52 is the main flow path of the cold air after entering the drawer 52 from the second air outlet 521, so that the cold air is evenly distributed inside the drawer 52. Guided by the interlayer channel, the cold air can be evenly diffused along the surface of the cold plate 53 to cover the food in the entire drawer 52.

[0058] This solution effectively solves the technical problems of uneven cold air distribution in the fresh-keeping area and poor food preservation effect by introducing the design of the cold plate 53 and the interlayer channel. The introduction of the cold plate 53 allows the cold air to flow evenly along its surface, while the interlayer channel ensures that the cold air can quickly and evenly cover the entire food area after entering the drawer 52, thereby improving the utilization efficiency of the cold air.

[0059] In some embodiments of the present application, the fruit and vegetable box cover 30 further includes a sealing strip; the sealing strip is disposed on the bevel edge of the sealing cover 32, and the sealing strip fits against the top edge of the drawer 52 when the fruit and vegetable box cover 30 is closed.

[0060] The main function of the sealing strip is to prevent cold air leakage and ensure the temperature in the fresh-keeping area is stable. The material is usually selected from rubber or silicone materials with high elasticity and aging resistance to ensure long-term reliability and durability. The design of the sealing strip fully considers the shape and size of the top edge of the drawer 52 to ensure tight fit and sealing effectiveness.

[0061] The sealing strip in this embodiment effectively solves the problems of cold air leakage and temperature fluctuation in the fresh-keeping area. The sealing strip fits tightly with the top edge of the drawer 52, forming an effective sealing barrier to prevent cold air from leaking out from the gap between the fruit and vegetable box cover 30 and the drawer 52. The utilization efficiency of cold air is improved, and the temperature in the fresh-keeping area is ensured to be stable.

[0062] In some embodiments of the present application, the cooling plate 53 is made of metal or ceramic material.

[0063] Specifically, when the cold plate 53 is made of metal material, such as stainless steel, aluminum alloy, etc., it has good thermal conductivity and strength, can quickly respond to the temperature change of the cold air, and evenly transfer the cold air to the food in the drawer 52. In addition, the metal material also has high corrosion resistance and wear resistance, which can ensure that the cold plate 53 maintains stable performance during long-term use.

[0064] When the cold plate 53 is made of ceramic material, such as alumina ceramic, silicon nitride ceramic, etc., its surface is smooth and not easy to absorb impurities, which can effectively prevent the problem of adhesion between the food and the cold plate 53. At the same time, the ceramic material also has high thermal stability and chemical stability, and can maintain stable performance at extreme temperatures, ensuring uniform distribution of cold air on the cold plate 53.

[0065] It is understandable that in actual applications, the material of the cold plate 53 can be selected according to functional requirements.

[0066] In some embodiments of the present application, the fresh-keeping area further includes an ultraviolet germicidal lamp; the ultraviolet germicidal lamp is arranged on the inner wall or the top of the drawer 52, and a contact sensor is arranged on the drawer cover 51, and the contact sensor is electrically connected to the ultraviolet germicidal lamp. The contact sensor is configured to: when it is detected that the drawer cover 51 is opened, the ultraviolet germicidal lamp is controlled to be extinguished, and when it is detected that the drawer cover 51 is closed, the ultraviolet germicidal lamp is controlled to be turned on.

[0067] The ultraviolet sterilization lamp is used to kill bacteria, viruses and other microorganisms that may exist in the drawer 52 to ensure the hygiene and safety of the food. The ultraviolet light it emits can destroy the DNA structure of microorganisms, thereby achieving the purpose of sterilization. The location of the ultraviolet sterilization lamp ensures that it can fully cover the space in the drawer 52 and perform sterilization without dead corners.

[0068] The contact sensor is used to detect the switch state of the drawer cover 51, and control the switch of the ultraviolet germicidal lamp according to the detection result. When the drawer cover 51 is detected to be open, the contact sensor will immediately control the ultraviolet germicidal lamp to turn off to avoid ultraviolet rays from causing harm to the human body; when the drawer cover 51 is detected to be closed, the contact sensor will control the ultraviolet germicidal lamp to turn on for sterilization.

[0069] In this embodiment, the ultraviolet sterilization lamp and the contact sensor effectively solve the problem of food hygiene and safety in the fresh-keeping area. The ultraviolet sterilization lamp can fully cover the space in the drawer 52, kill possible microorganisms, and ensure the hygiene and safety of the food. At the same time, the design of the contact sensor enables the ultraviolet sterilization lamp to automatically switch on and off when the drawer cover 51 is opened or closed, avoiding the harm of ultraviolet rays to the human body and improving the safety of use.

[0070] In actual application, when it is necessary to take or put food, the drawer mask 51 is opened. At this time, the contact sensor will detect the open state of the drawer mask 51 and immediately control the ultraviolet sterilization lamp to turn off to avoid ultraviolet rays from causing harm to the human body. After taking or putting food, close the drawer mask 51. At this time, the contact sensor will detect the closed state of the drawer mask 51 and control the ultraviolet sterilization lamp to turn on for sterilization. It is understandable that the user can set the sterilization time and frequency of the ultraviolet sterilization lamp as needed to meet the freshness requirements of different food ingredients.

[0071] Another aspect of the present application provides a refrigerator, comprising a sealing structure of a fresh-keeping area as in any one of the above embodiments, Figure 3 As shown, it also includes a refrigerated inner container 10, and the air duct cover 20 also includes: a cover 21; the fresh-keeping area is arranged in the refrigerated inner container 10, and the cover 21 is arranged between the fresh-keeping area and the refrigerated inner container 10.

[0072] The refrigerated inner tank 10 provides a stable refrigerated environment for the fresh-keeping area. Its internal space is carefully planned to ensure that the fresh-keeping area can fully utilize the refrigeration capacity of the refrigerated inner tank 10 while maintaining relative independence from other refrigerated areas.

[0073] The air duct cover plate 20 not only serves to connect the fresh-keeping area with the refrigerated inner tank 10, but also further protects the sealing structure of the fresh-keeping area through the cover plate 21 thereon. The design of the cover plate 21 fully considers the characteristics of the sealing structure of the fresh-keeping area, ensuring that key components such as the sealing strip will not be disturbed or damaged by the external environment during long-term use. At the same time, the cover plate 21 also has a certain heat insulation performance, which can effectively reduce the heat exchange between the fresh-keeping area and the refrigerated inner tank 10 and improve the refrigeration efficiency.

[0074] On the other hand, the refrigerator provided in the embodiment of the present application effectively solves the technical problems of insufficient utilization of the internal space of the refrigerator, poor preservation effect and low refrigeration efficiency by integrating the sealing structure of the fresh-keeping area, the refrigerated inner tank 10 and the air duct cover 20. The fresh-keeping area is set in the internal space of the refrigerated inner tank 10, forming an independent fresh-keeping area, so that the food can be preserved more accurately. At the same time, the design of the air duct cover 20 and the cover 21 not only protects the sealing structure of the fresh-keeping area, but also improves the refrigeration efficiency and ensures the stability of the temperature inside the refrigerator.

[0075] In some embodiments of the present application, continue to refer to Figure 3 As shown, there are two fresh-keeping areas, including a left fresh-keeping area 40 and a right fresh-keeping area 50, and the left fresh-keeping area 40 and the right fresh-keeping area 50 are arranged side by side.

[0076] It is understandable that the two fresh-keeping areas are arranged side by side in the internal space of the refrigerated inner container 10, and are independent and fully functional. The left fresh-keeping area 40 and the right fresh-keeping area 50 are separated by the side wall of the refrigerated inner container 10, ensuring the independence between the two. At the same time, each fresh-keeping area is equipped with the sealing structure, the cold plate 53, the ultraviolet sterilization lamp, and the air duct cover 20 as described in the above embodiments to ensure its normal fresh-keeping function.

[0077] The left fresh-keeping area 40 and the right fresh-keeping area 50 provide users with more flexible and diverse food storage options. Users can store food in the left fresh-keeping area 40 and the right fresh-keeping area 50 according to the type, size and fresh-keeping requirements of the food, so as to achieve more accurate fresh-keeping processing. The left fresh-keeping area 40 and the right fresh-keeping area 50 are separated by the side wall of the refrigerated inner container 10 to ensure the independence between the two.

[0078] The parallel arrangement of the left fresh-keeping area 40 and the right fresh-keeping area 50 effectively solves the problems of insufficient utilization of the internal space of the refrigerator, diversified food preservation requirements, and mutual influence of food. The parallel arrangement of the two fresh-keeping areas not only improves the utilization rate of the internal space of the refrigerator, but also provides users with more flexible and diverse food storage options.

[0079] In some embodiments of the present application, it also includes: a first temperature sensor, a second temperature sensor and a refrigerator wind control system; the first temperature sensor and the second temperature sensor are respectively arranged in the inner cavity of the drawer bucket 52 of the left part 40 of the fresh-keeping area and the right part 50 of the fresh-keeping area, and are both electrically connected to the refrigerator wind control system.

[0080] The first temperature sensor is configured to: detect the real-time temperature in the left part 40 of the fresh-keeping area, obtain first temperature data, and send the first temperature data to the refrigerator wind control system; the second temperature sensor is configured to: detect the real-time temperature in the right part 50 of the fresh-keeping area, obtain second temperature data, and send the second temperature data to the refrigerator wind control system.

[0081] The first temperature sensor and the second temperature sensor are used to detect the temperature in the left portion 40 and the right portion 50 of the fresh-keeping area in real time. In this way, the refrigerator wind control system can grasp the temperature conditions of the fresh-keeping area in real time, thereby performing precise temperature control.

[0082] The refrigerator wind control system is configured to receive first temperature data and second temperature data, and when the first temperature data and the second temperature data are higher than a preset temperature, start the fan to blow air from the air nozzles 22 of the left part 40 and the right part 50 of the fresh-keeping area respectively.

[0083] The main function of the refrigerator wind control system is to receive temperature data from the first temperature sensor and the second temperature sensor, and determine whether to start the fan for cooling based on these data and the preset temperature. When it is detected that the temperature in the fresh-keeping area is higher than the preset temperature, the refrigerator wind control system will immediately start the fan and blow air through the air nozzle 22 to the left part 40 of the fresh-keeping area and the right part 50 of the fresh-keeping area, respectively, to achieve rapid cooling and uniform cooling.

[0084] In this embodiment, the preservation effect of food is improved and the preservation period of food is extended through precise temperature control and uniform cooling. Because the temperature of the fresh-keeping zone is precisely controlled, unnecessary refrigeration energy consumption is avoided, thereby reducing the overall energy consumption of the refrigerator. Users can flexibly set the preset temperature according to the preservation requirements of food, so as to manage food more conveniently.

[0085] In some embodiments of the present application, the air duct cover 20 also includes a wind direction adjusting device; the wind direction adjusting device is arranged at the air nozzle 22, and the wind direction adjusting device is electrically connected to the refrigerator wind control system; the refrigerator wind control system is also configured to: according to the difference between the first temperature data and the second temperature data and the preset temperature, control the direction of the wind blown out from the air nozzle 22 of the left part 40 of the fresh-keeping area and the right part 50 of the fresh-keeping area by the wind direction adjusting device respectively.

[0086] The wind direction adjusting device is used to adjust the direction of the wind blown out from the wind nozzle 22. By changing the wind direction, the cold wind can be more effectively delivered to every corner of the fresh-keeping area to ensure uniform temperature distribution. The wind direction adjusting device may adopt a shutter type, a rotary type or other adjustable structure to meet different temperature control requirements.

[0087] The wind direction adjustment device combined with the precise control of the refrigerator wind control system effectively solves the problems of uneven temperature distribution inside the refrigerator, poor preservation effect and excessive energy consumption. Specifically, the refrigerator wind control system accurately controls the start-up of the fan, the air volume and the angle of the wind direction adjustment device according to the difference between the temperature data and the preset temperature, thereby achieving precise control of the temperature of the fresh-keeping area and uniform cooling. This precise temperature and wind direction control further reduces the energy consumption of the refrigerator.

[0088] As can be seen from the above content, the present application provides a sealing structure and refrigerator for a fresh-keeping area, including: a fruit and vegetable box cover and a fresh-keeping area; the fresh-keeping area includes: a drawer mask and a drawer bucket, and the side of the sealing cover close to the fresh-keeping area is a slope, and the slope fits the top edge of the drawer bucket. The slope structure can fit the top edge of the drawer bucket tightly to form an effective sealing effect. The sealing cover can slide smoothly when the drawer bucket is opened, reducing friction and resistance. The sealing enables the fresh-keeping area to effectively lock the moisture of fruits and vegetables and avoid the gas flow in the refrigerator with moisture. The air duct structure of the air inlet, the first air outlet and the second air outlet ensures the air inlet and outlet of the sealed space, avoiding the reduction of the refrigeration rate due to the sealing. It can also reduce the molecular movement and exchange between the food inside the drawer and the food in other areas, prevent the food from odor mixing, and improve the taste of the food. It effectively improves the refrigeration uniformity of food storage, avoids local deterioration of food due to uneven cooling, and improves the fresh-keeping effect of food.
