Description

Technical Field

[0001] This application relates to the field of refrigerator technology, for example to a sealing device and a refrigerator. Background Technology

[0002] Currently, with the improvement of people's living standards, the requirements for refined food storage are increasing, and the demand for subdivided spaces inside refrigerators is becoming more and more significant, especially for storing foods and items with odors. However, the existing storage boxes and fruit and vegetable drawers in refrigerators often lead to odor mixing problems due to poor sealing.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] Ensure good sealing when storing food in the refrigerator. Summary of the Invention

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0006] This disclosure provides a sealing device and a refrigerator to solve the problem of how to ensure good sealing when storing food in a refrigerator.

[0007] In some embodiments, the sealing device includes a housing, and further includes: a lid, a pressure cap, an exhaust module, and an intake module; the lid and the housing define a sealed storage space, the lid including a recess and an elastic member disposed within the recess; the pressure cap and the recess of the lid define a sealed cavity and are connected to the lid via the elastic member, the pressure cap being movable axially along the elastic member; the exhaust module is disposed on the pressure cap and can exhaust gas from the cavity when the pressure cap is pressurized; the intake module is disposed on the recess and opposite to the exhaust module, and can allow gas from the storage space to enter the cavity when there is a pressure difference between the storage space and the cavity.

[0008] In some embodiments, the refrigerator includes the sealing device described above.

[0009] The refrigerator for sealing provided in this disclosure can achieve the following technical effects:

[0010] When the pressure cap is pressed, the gas inside the sealed cavity defined by the pressure cap and the lid cannot escape, causing the gas pressure inside the cavity to rise. This leads to an increase in the pressure difference between the inside and outside of the exhaust module. When the gas pressure inside the cavity exceeds the elasticity of the internal structure of the exhaust module, the exhaust module begins to exhaust gas, causing the pressure cap to move axially. When the pressure cap stops moving, the gas pressure inside the cavity is less than atmospheric pressure, and the exhaust module stops exhausting gas. Under the action of the elastic component, the pressure cap continues to move and returns to its original position. At this time, the gas pressure inside the cavity gradually decreases, causing the pressure difference between the inside and outside of the intake module to increase. When the gas pressure in the sealed storage space defined by the lid and the box body exceeds the elasticity of the internal structure of the intake module, the intake module begins to intake gas, allowing the gas in the storage space to enter the cavity. Because the lid and body are sealed together, the air pressure inside the box decreases. Under the action of external atmospheric pressure, the lid and body are pressed together to form a seal. Therefore, good airtightness is ensured when storing food in the refrigerator, meeting users' requirements for refined food storage and fulfilling the need for subdivided spaces inside the refrigerator. This is especially true for storing odorous foods and other items in the refrigerator, solving the problem of odor mixing caused by poor sealing in existing refrigerator storage boxes and fruit and vegetable boxes.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0025] Combination Figure 1 As shown, this embodiment of the present disclosure provides a sealing device, including a housing 01, a lid 02, a pressure cap 03, an exhaust module 04, and an intake module 05. The lid 02 and the housing 01 define a sealed storage space 21. The lid 02 includes a recess and an elastic member 06 disposed within the recess. The pressure cap 03 and the recess of the lid 02 define a sealed cavity 32 and are connected to the lid 02 via the elastic member 06. The pressure cap 03 is movable along the axial direction of the elastic member 06. The exhaust module 04 is disposed on the pressure cap 03 and can exhaust gas from the cavity 32 when the pressure cap 03 is under pressure. The intake module 05 is disposed on the recess and opposite to the exhaust module 04, and can allow gas from the storage space 21 to enter the cavity 32 when there is a pressure difference between the storage space 21 and the cavity 32.

[0026] Using the sealing device provided in this embodiment, when the pressure cap 03 is pressed, the gas in the sealed cavity 32 defined by the recesses of the pressure cap 03 and the cover 02 cannot be discharged, causing the gas pressure in the cavity 32 to increase. This leads to an increase in the pressure difference between the inside and outside of the exhaust module 04. When the gas pressure in the cavity 32 is greater than the elasticity of the internal structure of the exhaust module 04, the exhaust module 04 begins to exhaust gas, allowing the gas in the cavity 32 to be discharged, and the pressure cap 03 moves axially. When the pressure cap 03 stops moving, the gas pressure in the cavity 32 is less than atmospheric pressure, and the exhaust module 04 stops exhausting gas. Under the action of the elastic member 06, the pressure cap 03 continues to move and returns to its original position. At this time, the gas pressure in the cavity 32 gradually decreases, causing an increase in the pressure difference between the inside and outside of the air intake module 05. When the gas pressure in the sealed storage space 21 defined by the cover 02 and the box body 01 is greater than the elasticity of the internal structure of the air intake module 05, the air intake module 05 begins to intake gas, allowing the gas in the storage space 21 to enter the cavity. Because the lid 02 and the body 01 are sealed, the air pressure inside the storage space 21 is reduced. Under the action of external atmospheric pressure, the lid 02 and the body 01 are pressed together to form a seal. Therefore, good sealing performance can be guaranteed when storing food in the refrigerator, meeting users' requirements for refined food storage and realizing the need for subdivided spaces inside the refrigerator. In particular, it solves the problem of odor transfer caused by poor sealing of existing refrigerator storage boxes, fruit and vegetable boxes, etc.

[0027] Optionally, such as Figure 2 As shown, the exhaust module 04 can be a one-way valve. This one-way valve includes an exhaust valve spring 41, an exhaust valve core 42, and an exhaust valve plug 43. When the air pressure inside the cavity 32 defined by the recessed portion of the cover and the housing increases, the pressure difference between the inside and outside of the exhaust valve core 42 increases. When the air pressure inside the cavity 32 exceeds the elastic force of the exhaust valve spring 41, the exhaust valve core 42 moves axially, opening the exhaust passage and allowing the gas inside the cavity 32 to escape. The cover 03 then moves axially. When the cover stops moving, the air pressure inside the cavity 32 is lower than atmospheric pressure. Under the action of the external gas and the exhaust valve spring 41, the exhaust valve core 42 returns to its original position, and the exhaust passage is closed.

[0028] Optionally, the intake module 05 can be a one-way valve. This one-way valve includes an intake valve spring 51, an intake valve core 52, and an intake valve plug 53. As the air pressure within the cavity 32 defined by the recessed portion of the cover and the housing gradually decreases, the pressure difference between the inner and outer sides of the intake valve core 52 continuously increases. When the air pressure within the storage space 21 defined by the cover and the housing exceeds the elastic force of the intake valve spring 51, the intake valve core 52 moves axially, the intake passage is opened, and the gas in the storage space 21 enters the cavity 32.

[0029] Optionally, the lid 02 also includes a first sealing structure 22, which defines a sealed storage space 21 between the lid 02 and the box body 01. The first sealing structure 22 ensures good airtightness of the storage space 21 defined between the lid 02 and the box body 01. When the air pressure inside the sealed storage space 21 decreases, the lid 02 and the box body 01 are pressed together under the action of external atmospheric pressure.

[0030] Optionally, the first sealing structure 22 can be a sealing ring. Using a sealing ring to achieve sealing is simple in structure and convenient in use and maintenance.

[0031] Optionally, the pressure cap 03 includes a second sealing structure 31, which defines a sealed cavity 32 between the pressure cap 03 and the recess of the lid 02. The second sealing structure 31 ensures good airtightness of the cavity 32 defined between the pressure cap 03 and the lid 02. When the pressure cap 03 is pressed, the gas inside the cavity 32 cannot escape, thereby increasing the air pressure inside the cavity 32.

[0032] Optionally, the second sealing structure 31 can be a sealing ring. Using a sealing ring to achieve sealing is simple in structure and convenient in use and maintenance.

[0033] Optionally, both the cover 02 and the pressure cap 03 further include a limiting member 07. This limiting member 07 is positioned around the intake module 05 and the exhaust module 04, defining a positioning space between the limiting member 07 and the intake module 05 and the exhaust module 04. The positioning space defined between the limiting member 07 and the intake module 05 and the exhaust module 04 provides an installation position for the elastic component 06, allowing the intake module 05 and the exhaust module 04 to be connected via the elastic component 06.

[0034] Optionally, the elastic component 06 extends into the positioning space and connects to the intake module 05 and the exhaust module 04.

[0035] Alternatively, the elastic component 06 may be a spring.

[0036] This disclosure provides a sealing device, combined with Figure 3 and Figure 4 As shown, it also includes a cover plate 08. One end of the cover plate 08 is fixed to the lid 02, and the other end extends into the recess, and is configured to restrict the pressure cap 03 from sliding out of the lid 02 axially. By extending the other end of the cover plate 08 into the recess, the movable position of the pressure cap 03 can be restricted, preventing the pressure cap 03 from sliding out of the lid 02 axially.

[0037] Optionally, the cover plate 08 includes an electronic tag 81 and an RF isolation plate 82. The electronic tag includes an identification pattern, and the electronic tag 81 is disposed in the groove enclosed by the cover plate 08 and the box cover 02; the RF isolation plate 82 is rotatably disposed on the cover plate 08, and an opening 83 is provided on the RF isolation plate 82. When the RF isolation plate 82 is rotated to the first position, the opening exposes the identification pattern and the RF signal.

[0038] Optionally, the electronic tag 81 can be written to and read from by an RFID (Radio Frequency Identification) reader, and the identification pattern is an icon of the food ingredient.

[0039] RFID technology is a type of automatic identification technology that uses radio frequency (RF) for non-contact, two-way data communication. It reads and writes data to a recording medium (electronic tag or RFID card) using RF to identify targets and exchange data. An RFID system is a non-contact automatic identification system that automatically identifies target objects and acquires relevant data via radio frequency signals. It consists of electronic tags, readers, and a computer network. The RFID system uses electronic tags to identify objects. These tags exchange data with the reader via radio waves. The reader transmits read / write commands from the host computer to the electronic tag and then sends the data returned by the tag back to the host computer. The host computer's data exchange and management system is responsible for storing, managing, and controlling the data information from the electronic tags.

[0040] In practical applications, when a user places food into the sealing device and presses the pressure cap 03, the gas inside the sealed cavity 32, defined by the pressure cap 03 and the recessed portion of the lid 02, cannot escape, causing the air pressure inside the cavity 32 to rise. This leads to an increase in the pressure difference between the inside and outside of the exhaust module 04. When the air pressure inside the cavity 32 exceeds the elasticity of the internal structure of the exhaust module 04, the exhaust module 04 begins to exhaust gas, causing the pressure cap 03 to move axially. When the pressure cap 03 stops moving, the air pressure inside the cavity 32 is less than atmospheric pressure, and the exhaust module 04 stops exhausting gas. Under the action of the elastic component 06, the pressure cap 03 continues to move and returns to its original position. At this time, the air pressure inside the cavity 32 gradually decreases, causing an increase in the pressure difference between the inside and outside of the air intake module 05. When the air pressure inside the sealed storage space 21 defined by the lid 02 and the box body 01 exceeds the elasticity of the internal structure of the air intake module 05, the air intake module 05 begins to intake gas, allowing the gas in the storage space 21 to enter the cavity. Because the lid 02 and the body 01 are sealed together, the air pressure inside the storage space 21 decreases. Under the action of external atmospheric pressure, the lid 02 and the body 01 are pressed together, thus sealing the food. Then, by rotating the RFID isolation plate 82, the user can see icons for various food items at the opening. The user selects the corresponding food item icon based on the item they placed inside. Since the RFID isolation plate only allows radio frequency transmission through its opening, it can shield the radio frequency of other electronic tags. The RFID reader can then identify the type of food item the user has placed in the sealed device, enabling categorized and zoned storage and management of the food.

[0041] This disclosure provides an apparatus for sealing, such as... Figure 4 As shown, it also includes a pressure relief valve 09. This pressure relief valve 09 is located on the cover 02. The sealing device can be easily opened by using the pressure relief valve 09. When the pressure relief valve 09 is pulled, external gas can enter the sealed storage space defined by the cover 02 and the box body. At this time, the internal and external gas pressures are the same, and the cover 02 can be opened.

[0042] Optionally, the pressure relief valve 09 includes a fixing part 91 and a sealing part 92. The fixing part 91 is disposed on the cover 02; the sealing part 92 is disposed on the fixing part 91 in an openable manner.

[0043] Alternatively, the pressure relief valve 09 can be made of soft rubber. This allows for easy opening of the seal 92, facilitating pressure relief in the storage space.

[0044] Combination Figure 5 As shown, this disclosure provides a refrigerator that includes the above-described sealing device.

[0045] Optionally, the refrigerator also includes a refrigeration compartment 10. This refrigeration compartment includes an air duct back panel 11, the aforementioned sealing device, and an RFID system. The air duct back panel 11 integrates an RFID reader, which can read information about the food placed inside; the RFID system can read and write information about the food. Therefore, based on RFID technology, food can be identified, stored, and managed. Each time the user operates the aforementioned sealing device, the information is updated in the electronic tag.
