A sealed structure for a food preservation area and a refrigerator

Abstract

This application provides a sealing structure for a fresh-keeping area and a refrigerator, including: a fruit and vegetable drawer cover and a fresh-keeping area; the fresh-keeping area includes: a drawer front cover and a drawer drawer. The side of the sealing cover closest to the fresh-keeping area is beveled, and the beveled surface fits the top edge of the drawer drawer. The beveled structure can tightly fit the top edge of the drawer drawer, forming an effective seal. This allows the sealing cover to slide smoothly when the drawer drawer is opened, reducing friction and resistance. The seal allows the fresh-keeping area to effectively lock in the moisture of fruits and vegetables, preventing moisture from being carried by airflow inside the refrigerator. The air duct structure of the air inlet, first air outlet, and second air outlet ensures air intake and exhaust within the sealed space, preventing a decrease in cooling rate due to the seal. It also reduces molecular movement and exchange between food inside the drawer and food in other areas, effectively improving the uniformity of cooling during food storage, preventing localized spoilage due to uneven cooling, and improving the freshness of the food.

[0040] Example implementations will now be described with reference to the drawings; however, example implementations can be implemented in many different forms and should not be construed as limited to the examples set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the inventive concept of example implementations to those skilled in the art. The described features, structures, or characteristics can be combined in any suitable manner in one or more implementations. In the following description, numerous specific details are provided to give a thorough understanding of implementations of the present application.

[0041] The fresh-keeping special area provides a more stable and suitable storage environment for food materials by controlling temperature and humidity fluctuations in the storage space, thereby maximizing the retention of the taste and flavor of food materials. In terms of the sealing structure of the fresh-keeping special area, existing technologies generally use a method of fixing the sealing cover plate relative to the drawer to achieve sealing. This design can ensure that the sealing cover plate closely fits the edge of the drawer when the drawer is closed, effectively preventing cold air leakage and maintaining the stability of the temperature and humidity in the fresh-keeping special area. However, when the drawer needs to be pulled out to place or take food materials, the user needs to further open the sealing cover plate, which is inconvenient for taking food.

[0042] To solve the above problems, the first aspect of the embodiment of the application provides a sealing structure of a fresh-keeping special area, referring to Figure 1 and Figure 2 As shown, it comprises an air duct cover plate 20, a fruit and vegetable box cover plate 30 and a fresh-keeping special area. The fresh-keeping special area in the embodiment is mainly composed of a drawer face cover 51 and a drawer bucket 52. The drawer face cover 51 is designed as a double-layer structure, which enhances its heat preservation performance, and the drawer bucket 52 is placed in the inner layer of the drawer face cover 51 for storing food materials.

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

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

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

[0046] The drawer face cover 51 and the drawer bucket 52 are the main structure of the fresh-keeping special area. The double-layer design of the drawer face cover 51 enhances the heat preservation performance, and the drawer bucket 52 provides sufficient storage space. Together, they provide a stable and suitable storage environment for food materials.

[0047] In practical applications, the user only needs to pull out the fresh-keeping area, and the drawer 52 and the sealing cover plate 32 are matched with inclined surfaces. When the fresh-keeping area is pulled out, the gap between the sealing cover plate 32 and the drawer 52 gradually expands, and the sealing is released. When the fresh-keeping area is pushed back, the gap between the sealing cover plate 32 and the drawer 52 gradually decreases until the sealing. The whole process is simple and fast, and there is no need to open and close the sealing cover plate 32 complicatedly, which greatly improves the convenience and efficiency of use. At the same time, the inclined surface design of the sealing cover plate 32 and the close fit of the drawer 52 also ensure the stability of the temperature and humidity in the fresh-keeping area, and provide the best storage environment for the food materials.

[0048] The air duct cover plate 20 comprises an air nozzle 22 which is communicated with the drawer face cover 51. Cold air is blown into by the air nozzle 22, which can be used for efficient cooling of the sealed fresh-keeping area, and realizes the fresh-keeping effect of the fresh-keeping area.

[0049] The fruit and vegetable box cover plate 30 is designed as a sliding structure, and the inclined surface design of the sealing cover plate 32 effectively solves the problem of inconvenient taking and placing of food materials in the traditional sealing structure of the fresh-keeping area. The user only needs to pull out the fresh-keeping area, without the need to completely open the sealing cover plate 32, thereby greatly improving the convenience and efficiency of use.

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

[0051] The air inlet 511 provided on the drawer face cover 51 is used to receive the cold air input from the air nozzle 22 of the air duct cover plate 20, and the first air outlet 512 is located at a proper position of the drawer face cover 51 to send the cold air to the surroundings of the drawer face cover 51, thereby maintaining the temperature balance in the fresh-keeping area. The second air outlet 521 is provided at the bottom of the drawer 52. The cold air forms a complete air path around the drawer face cover 51, and the cold air can uniformly cover the food materials in the drawer 52, thereby maintaining the freshness and taste of the food materials.

[0052] Specifically, the air duct cover plate 20, the fruit and vegetable box cover plate 30 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 face cover 51 along the air inlet 511 and the first air outlet 512 provided on the drawer face cover 51, and leaves the fresh-keeping area from the second air outlet 521 provided at the bottom of the drawer 52.

[0053] Cold air is blown into by the air nozzle 22 provided on the air duct cover plate 20 and leaves from the second air outlet 521 provided on the drawer 52, thereby forming an air path. Not only can the sealed fresh-keeping area be efficiently cooled, but also the gas exchange between the sealed fresh-keeping area and the refrigerated space can be effectively avoided, the humidity of the fresh-keeping area is improved, and the fresh-keeping effect is improved.

[0054] In this embodiment, the design of the air duct cover plate 20 and its air nozzle 22 allows the cold air to be precisely delivered into the fresh-keeping zone, avoiding waste and ineffective circulation of the cold air. The air inlet 511, the first air outlet 512 of the drawer face cover 51, and the second air outlet 521 of the drawer bin 52 work together to ensure that the temperature distribution in the fresh-keeping zone is more uniform, avoiding the adverse effects of temperature fluctuations on food materials. By precisely controlling the input and output of cold air, this scheme ensures that food materials can be stored in the best environment in the fresh-keeping zone.

[0055] In some embodiments of the present application, the fresh-keeping zone further comprises: a uniform cooling plate 53, which is located at the bottom of the inner cavity of the drawer bin 52; the uniform cooling plate 53 has a certain distance from the surface of the bottom of the inner cavity of the drawer bin 52, and the distance forms a sandwich channel, which is in communication with the second air outlet 521.

[0056] As one of the core components in the fresh-keeping zone, the main function of the uniform cooling plate 53 is to uniformly distribute the cold air to ensure that the food materials in the drawer bin 52 are evenly cooled. Considering the natural diffusion characteristics of the cold air during the flow process, the cold air can flow uniformly along the surface of the uniform cooling plate 53 through reasonable structural layout.

[0057] In this embodiment, the sandwich channel formed by the distance between the uniform cooling plate 53 and the bottom of the inner cavity of the drawer bin 52 is the main flow path for the cold air after entering the drawer bin 52 from the second air outlet 521, which allows the cold air to be evenly distributed inside the drawer bin 52. Guided by the sandwich channel, the cold air can uniformly diffuse along the surface of the uniform cooling plate 53, covering all the food materials in the drawer bin 52.

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

[0059] In some embodiments of the present application, the fruit and vegetable box cover plate 30 further comprises a sealing strip; the sealing strip is arranged on the inclined edge of the sealing cover plate 32, and the sealing strip is in close contact with the top edge of the drawer bin 52 when the fruit and vegetable box cover plate 30 is closed.

[0060] The main function of the sealing strip is to prevent the leakage of cold air and ensure the stability of the temperature in the fresh-keeping zone. Its material is usually rubber or silicone material with high elasticity and aging resistance to ensure the reliability and durability of long-term use. The design of the sealing strip fully considers the shape and size of the top edge of the drawer bin 52 to ensure the tightness of the fit and the effectiveness of the seal.

[0061] The sealing strip in the embodiment effectively solves the problems of cold air leakage and temperature fluctuation in the fresh-keeping area. The sealing strip closely fits the top edge of the drawer compartment 52, forming an effective sealing barrier that prevents cold air from leaking out of the gap between the fruit and vegetable box cover plate 30 and the drawer compartment 52. This improves the utilization efficiency of cold air and ensures the stability of the temperature in the fresh-keeping area.

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

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

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

[0065] It can be understood that in actual application, the material of the uniform cooling plate 53 can be selected according to functional needs.

[0066] In some embodiments of the present application, the fresh-keeping area also includes an ultraviolet sterilization lamp; the ultraviolet sterilization lamp is arranged on the inner wall or top of the drawer compartment 52, and a contact sensor is arranged on the drawer cover 51, and the contact sensor is electrically connected with the ultraviolet sterilization lamp. The contact sensor is configured to: when detecting that the drawer cover 51 is opened, control the ultraviolet sterilization lamp to be turned off; and when detecting that the drawer cover 51 is closed, control the ultraviolet sterilization lamp to be turned on.

[0067] The ultraviolet sterilization lamp is used to kill bacteria, viruses and other microorganisms that may exist in the drawer compartment 52, to ensure the hygiene and safety of food materials. The ultraviolet light emitted by the ultraviolet sterilization lamp can damage the DNA structure of microorganisms, thereby achieving the purpose of sterilization. The setting position of the ultraviolet sterilization lamp ensures that it can fully cover the space in the drawer compartment 52, and sterilize without dead angles.

[0068] The contact sensor is used to detect the opening and closing state of the drawer cover 51, and control the opening and closing of the ultraviolet sterilization lamp according to the detection result. When the drawer cover 51 is detected to be opened, the contact sensor will immediately control the ultraviolet sterilization lamp to be turned off, to avoid harm to the human body caused by ultraviolet rays; when the drawer cover 51 is detected to be closed, the contact sensor will control the ultraviolet sterilization lamp to be turned on for sterilization.

[0069] In this embodiment, the health and safety of food materials in the fresh-keeping area are effectively addressed by the ultraviolet sterilization lamp and the contact sensor. The ultraviolet sterilization lamp can comprehensively cover the space in the drawer compartment 52, killing possible microorganisms and ensuring the health and safety of food materials. At the same time, the design of the contact sensor enables the ultraviolet sterilization lamp to automatically turn on and off when the drawer cover 51 is opened or closed, avoiding harm to the human body and improving the safety of use.

[0070] In actual application, when it is necessary to take or place food materials, the drawer cover 51 is opened. At this time, the contact sensor detects the opening state of the drawer cover 51 and immediately controls the ultraviolet sterilization lamp to be turned off, so as to avoid harm to the human body caused by ultraviolet rays. After the food materials are taken or placed, the drawer cover 51 is closed. At this time, the contact sensor detects the closing state of the drawer cover 51 and controls the ultraviolet sterilization lamp to be turned on for sterilization treatment. It can be understood that the user can set the sterilization time and frequency of the ultraviolet sterilization lamp according to needs to meet the fresh-keeping needs of different food materials.

[0071] Another aspect of the application provides a refrigerator, which includes the sealing structure of any one of the fresh-keeping areas in the above embodiments, and refers to Figure 3 The refrigerator further includes a refrigeration inner container 10, and the air duct cover plate 20 further includes a cover plate 21. The fresh-keeping area is arranged in the refrigeration inner container 10, and the cover plate 21 is arranged between the fresh-keeping area and the refrigeration inner container 10.

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

[0073] The air duct cover plate 20 not only serves as a connection between the fresh-keeping area and the refrigeration inner container 10, but also realizes further protection of 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 certain heat insulation performance, which can effectively reduce the heat exchange between the fresh-keeping area and the refrigeration inner container 10 and improve the refrigeration efficiency.

[0074] The refrigerator provided by another aspect of the embodiments 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 preservation area, the refrigeration liner 10, and the air duct cover plate 20. The preservation area is arranged in the internal space of the refrigeration liner 10, forming an independent preservation area, so that the food materials can be subjected to more accurate preservation treatment. At the same time, the design of the air duct cover plate 20 and the cover plate 21 not only protects the sealing structure of the preservation area, but also improves the refrigeration efficiency and ensures the stability of the internal temperature of the refrigerator.

[0075] In some embodiments of the present application, continuing to refer to Figure 3 As shown in the figure, the preservation area has two parts, including: the left part 40 of the preservation area and the right part 50 of the preservation area, and the left part 40 of the preservation area and the right part 50 of the preservation area are arranged side by side.

[0076] It can be understood that the two preservation areas are arranged side by side in the internal space of the refrigeration liner 10, and are independent and complete in function. The left part 40 of the preservation area and the right part 50 of the preservation area are separated by the side wall of the refrigeration liner 10, ensuring the independence between the two. At the same time, each preservation area is equipped with components such as the sealing structure, the uniform cooling disc 53, the ultraviolet sterilization lamp, and the air duct cover plate 20 as described in the foregoing embodiments, to ensure its normal preservation function.

[0077] The left part 40 of the preservation area and the right part 50 of the preservation area provide users with more flexible and diverse food material storage options. Users can store food materials in the left part 40 of the preservation area and the right part 50 of the preservation area according to the types, sizes, and preservation needs of the food materials, to achieve more accurate preservation treatment. The left part 40 of the preservation area and the right part 50 of the preservation area are separated by the side wall of the refrigeration liner 10, ensuring the independence between the two.

[0078] Through the side-by-side left part 40 of the preservation area and the right part 50 of the preservation area, the problems of insufficient utilization of the internal space of the refrigerator, diverse preservation needs of food materials, and mutual influence of food materials are effectively solved. The side-by-side arrangement of the two preservation areas not only improves the utilization rate of the internal space of the refrigerator, but also provides users with more flexible and diverse food material storage options.

[0079] In some embodiments of the present application, further comprising: a first temperature sensor, a second temperature sensor, and a refrigerator control system; the first temperature sensor and the second temperature sensor are respectively arranged in the inner cavity of the drawer 52 of the left part 40 of the preservation area and the right part 50 of the preservation area, and are electrically connected with the refrigerator control system.

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

[0081] The first temperature sensor and the second temperature sensor are used to detect the temperature in the left part 40 and the right part 50 of the fresh-keeping zone in real time. In this way, the refrigerator control system can real-time grasp the temperature condition of the fresh-keeping zone, so as to perform accurate temperature control.

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

[0083] The main function of the refrigerator 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 refrigeration according to these data and the preset temperature. When it is detected that the temperature in the fresh-keeping zone is higher than the preset temperature, the refrigerator control system will immediately start the fan, and the fan blows air from the air outlets 22 to the left part 40 and the right part 50 of the fresh-keeping zone, respectively, to achieve rapid cooling and uniform refrigeration.

[0084] In this embodiment, accurate temperature control and uniform refrigeration are achieved, which improves the fresh-keeping effect of food materials and prolongs the fresh-keeping period of food materials. Since accurate control of the temperature of the fresh-keeping zone is achieved, unnecessary refrigeration energy consumption is avoided, thereby reducing the overall energy consumption of the refrigerator. The user can flexibly set the preset temperature according to the fresh-keeping requirement of the food materials, thereby more conveniently managing the food materials.

[0085] In some embodiments of the present application, the air duct cover plate 20 further comprises an air direction adjusting device; the air direction adjusting device is arranged at the air outlet 22, and the air direction adjusting device is electrically connected with the refrigerator control system; the refrigerator control system is further configured to control the direction of the air blown from the air outlets 22 of the left part 40 and the right part 50 of the fresh-keeping zone by the air direction adjusting device according to the difference between the first temperature data and the second temperature data and the preset temperature.

[0086] The air direction adjusting device is used to adjust the direction of the air blown from the air outlet 22. By changing the air direction, the cold air can be more effectively sent to every corner of the fresh-keeping zone, ensuring uniform distribution of temperature. The air direction adjusting device can adopt a louvered, rotary or other adjustable structure to adapt to different temperature control requirements.

[0087] The air direction adjusting device effectively solves the problems of uneven temperature distribution in the refrigerator, poor preservation effect and excessive energy consumption in combination with the precise control of the refrigerator air control system. Specifically, the refrigerator air control system accurately controls the start of the fan, the air outlet volume and the angle of the air direction adjusting device according to the difference between the temperature data and the preset temperature, thereby realizing accurate control and uniform refrigeration of the temperature of the preservation area. This precise temperature and air direction control further reduces the energy consumption of the refrigerator.

[0088] From the above, the application provides a sealing structure of a preservation area and a refrigerator, which comprises a fruit and vegetable box cover plate and a preservation area. The preservation area comprises a drawer face cover and a drawer bucket. One side of the sealing cover plate close to the preservation area is a slope, and the slope is attached to the top edge of the drawer bucket. The slope structure can tightly fit the top edge of the drawer bucket to form an effective sealing effect. The sealing cover plate can smoothly slide when the drawer bucket is opened, reducing friction and resistance. The sealing allows the preservation area to effectively lock the moisture of fruits and vegetables, avoiding the flow of water in the refrigerator. The air inlet, the first air outlet and the second air outlet ensure the air inlet and outlet of the sealed space, avoiding the reduction of refrigeration rate caused by sealing. It can also reduce the molecular movement and exchange between the food in the drawer and the food in other areas, prevent food from being mixed, and improve the taste of food. It effectively improves the refrigeration uniformity of food storage, avoids local deterioration of food due to uneven cooling, and improves the preservation effect of food.
