Description

Technical Field

[0001] This application is a divisional application of the Chinese invention patent application with application number 201911055688.2, application date October 31, 2019, and invention name “Storage device for refrigerator and refrigerator having the same”. Background Art

[0002] Controlled atmosphere preservation technology is a technology that extends the storage life of food by adjusting the ambient gas. In the field of refrigerators, by setting up a deoxygenation component and utilizing its electrochemical reaction to consume internal oxygen, a low-oxygen atmosphere can be created, which can improve the preservation effect. The storage container used in the refrigerator in the prior art has a relatively closed space that can weaken the exchange of internal and external gases. By providing an opening on the storage container and installing the deoxygenation component at the position of the opening, the oxygen content in the storage container can be reduced. However, the deoxygenation component also generates water while consuming internal oxygen. The relatively closed storage container prevents water vapor from being discharged. The presence of excessive water vapor can easily lead to condensation or dripping, affecting the preservation effect and reducing the user experience.

[0035] Figure 1 Refrigerator 10 is a schematic perspective view of a refrigerator 10 according to one embodiment of the present invention. Refrigerator 10 generally includes a housing 100 and a storage device 200. Housing 100 defines a storage compartment; in this embodiment, there may be multiple storage compartments, including a refrigeration compartment 110 and a freezer compartment 120. In other alternative embodiments, there may be only one storage compartment, namely, refrigeration compartment 110.

[0036] Figure 2 yes Figure 1 The schematic diagram of the storage device 200 for the refrigerator 10 is shown. Figure 3 yes Figure 2 Schematic exploded view of a storage device 200 for a refrigerator 10 is shown. The storage device 200 is disposed at the bottom of the refrigerating compartment 110 and includes a storage container 210, an oxygen removal and moisture permeation assembly 300, and a cover 350.

[0037] The storage container 210 has a storage space 213 formed therein. The storage container 210 may be a drawer, which is composed of a container body 211 and a pull-out portion 212. The drawer is pull-outably arranged at the bottom of the refrigerating compartment 110 of the refrigerator 10 to open or close the storage space 213.

[0038] Figure 4 yes Figure 3 The schematic diagram of the container body 211 of the storage container 210 of the storage device 200 for the refrigerator 10 is shown. Figure 5 yes Figure 3 Another schematic diagram of the container body 211 of the storage container 210 of the storage device 200 for the refrigerator 10 is shown. A gas permeable area 221 and a non-gas permeable area 222 are provided on the wall surface of the storage container 210. Preferably, the wall surface can be the top wall surface of the storage container 210, that is, the gas permeable area 221 is located on the top wall surface of the storage container. The top wall surface of the storage container 210 can be rectangular in shape, and the gas permeable area 221 can also be rectangular in shape. The gas permeable area 221 is provided in the middle position of the top wall surface, and the area between the gas permeable area 221 and the outer periphery of the top wall surface is the non-gas permeable area 222. The gas permeable area 221 is provided with through holes 410 arranged in an array, and the gas in the storage container 210 can escape from the through holes 410. The gas permeable area 221 includes a deoxygenation area 420 and a dehydration area 430. The deoxygenation zone 420 is located in the middle of the breathable area 221, and the deoxygenation zone 420 is recessed into the storage space 213 to form a recessed portion 421, and the recessed portion 421 can accommodate external components. The dewatering zone 430 is close to the deoxygenation zone 420 and is located on both sides of the deoxygenation zone 420; a plurality of columns 431 are provided on the side of the dewatering zone 430 facing away from the storage space 213. The non-air-permeable area 222 is not provided with a through hole and is in a closed state. A plurality of screw hole columns 440 are also provided on the top wall of the storage container 210. The plurality of screw hole columns 440 are located on the periphery of the breathable area 221, that is, the portion where the non-air-permeable area 222 and the breathable area 221 meet, and are used to connect and fix with external components.

[0039] Figure 6 yes Figure 3 Schematic diagram of a deoxygenating and moisture permeable assembly 300 for a storage device 200 of a refrigerator 10. The deoxygenating and moisture permeable assembly 300 is disposed on the storage container 210, preferably above the top wall of the storage container 210, and includes a support plate 310, a deoxygenating assembly 320, a fan assembly 330, and a moisture permeable membrane assembly 340.

[0040] The support plate 310 covers the breathable area 221, forming the skeleton of the deoxygenation and moisture permeability component 300, and has a receiving cavity for accommodating the deoxygenation component 320, the fan component 330, and the moisture permeability membrane group 340. The deoxygenation component 320, the fan component 330, and the moisture permeability membrane group 340 can be respectively installed in the receiving cavity and thus integrated with the support plate 310.

[0041] The integrated deoxygenation and moisture permeability assembly 300 includes a deoxygenation assembly 320 with a deoxygenation function and a fan assembly 330 with an air supply function, and also includes a moisture permeability membrane group 340 with a moisture permeability function, and has both deoxygenation and moisture permeability functions; the integrated deoxygenation and moisture permeability assembly 300 can be installed above the breathable area 221 at one time, avoiding step-by-step installation, simplifying the installation steps, and being easy to operate and having low installation difficulty.

[0042] Figure 7 yes Figure 6 The schematic diagram of the support plate 310 of the deoxygenation and moisture permeation assembly 300 is shown. Figure 8 yes Figure 6 Another schematic diagram of the support plate 310 of the deoxygenation and moisture permeation assembly 300 is shown. Figure 9 yes Figure 8 A schematic partial enlarged view of point A is shown. The support plate 310 forms a first accommodating chamber 311 above the side facing away from the deoxidation zone 420. In this embodiment, the support plate 310 may form the first accommodating chamber 311 above the side facing away from the deoxidation zone 420. The bottom wall of the first accommodating chamber 311 is provided with an opening 511. The periphery of the opening 511 extends toward the sidewall of the first accommodating chamber 311 to form a support platform 512. The support platform 512 confines the deoxidation assembly 320 to the bottom of the first accommodating chamber 311. That is to say, the portion of the support plate 310 located above the deoxygenation zone 420 is recessed toward the deoxygenation zone 420 to form a first accommodating cavity 311, and the outer shape of the first accommodating cavity 311 is adapted to the outer shape of the above-mentioned recessed portion 421 so that the first accommodating cavity 311 can be just inserted into the interior of the recessed portion 421; the bottom of the first accommodating cavity 311 includes an opening 511 and a support 512, the opening 511 is configured to allow gas escaping from the deoxygenation zone 420 to pass through, the support 512 is configured to receive the deoxygenation component 320, and a support screw hole 513 is provided on the support 512, and the deoxygenation component 320 can be fixed to the support 512 by screwing.

[0043] A second accommodating chamber 312 is formed in the portion of the support plate 310 facing above the dewatering area 430. Multiple retaining claws 514 are provided on the sidewalls of the second accommodating chamber 312. These retaining claws 514 confine the moisture-permeable membrane assembly 340 within the second accommodating chamber 312. In other words, the moisture-permeable membrane assembly 340 is positioned between the dewatering area 430 and the support plate 310, and the retaining claws 514 secure the moisture-permeable membrane assembly 340 within the second accommodating chamber 312. The bottom wall of the second accommodating chamber 312 also has an array of through-holes 530 arranged therein, configured to allow water vapor that permeates through the moisture-permeable membrane assembly 340 to escape through the through-holes 530.

[0044] The support plate 310 is provided with a first accommodating chamber 311 for accommodating the deaerator assembly 320 and the fan assembly 330, and a second accommodating chamber 312 for accommodating the moisture-permeable membrane assembly 340. The position and shape of the first accommodating chamber 311 correspond to those of the deaerator section 420, while the position and shape of the second accommodating chamber 312 correspond to those of the dewatering section 430. This allows the support plate 310 to be directly placed over the top wall of the storage container 210 for quick installation. The second accommodating chamber 312 of the support plate 310 is located adjacent to the first accommodating chamber 311, allowing the moisture-permeable membrane assembly 340 to be in close proximity to the deaerator assembly 320. This allows water vapor generated by the electrolysis reaction in the deaerator assembly 320 to be quickly discharged through the moisture-permeable membrane assembly 340, preventing excessive water vapor from being retained within the storage device 200 and facilitating the maintenance of humidity within the storage device 200 within an appropriate range.

[0045] Figure 10 yes Figure 6 The schematic diagram of the fan assembly 330 and the deoxidation assembly 320 of the deoxidation and moisture permeation assembly 300 is shown. Figure 11 yes Figure 10 The schematic diagram of the deoxidation assembly 320 is shown. Figure 12 yes Figure 12 The schematic exploded view of the deoxidizer assembly 320 is shown. The deoxidizer assembly 320 is disposed at the bottom of the first accommodating chamber 311 and is configured to consume oxygen within the storage space 213 through an electrolytic reaction under the action of an electrolytic voltage. In other words, the deoxidizer assembly 320 is disposed within the aforementioned recessed portion 421.

[0046] Since the oxygen density is relatively high and concentrated at the bottom of the storage container 210, and the oxygen concentration away from the bottom is relatively low, the deoxidation zone 420 is set to be recessed into the storage space 213, which can promote the deoxidation component 320 to fully contact with the oxygen in the storage space 213 and increase the rate of the electrochemical reaction.

[0047] The deoxidizing assembly 320 includes a mother plate 321 , an anode plate 322 , a cathode plate 323 , and a proton exchange membrane 324 sandwiched between the cathode plate 323 and the anode plate 322 .

[0048] The motherboard 321 forms the base of the deoxidizing assembly 320, and a notch 521 is provided in the middle part thereof, and the notch 521 can be rectangular; internal screw holes 522 are provided around the notch 521 for fixing with other components of the deoxidizing assembly 320 by screw connection, and external screw holes 523 are also provided on the edge of the motherboard 321 for fixing with the support 512 of the first accommodating chamber 311 by screw connection. The side of the cathode plate 323 facing away from the proton exchange membrane 324 is exposed above the deoxidation zone 420 and faces the interior of the storage space 213. It communicates with the storage space 213 via the through-holes 410 in the deoxidation zone 420 and the notch 521 in the mother plate 321. The cathode plate 323 is configured to utilize hydrogen ions and oxygen to react and produce water, thereby consuming oxygen within the storage space 213. The side of the anode plate 322 facing away from the proton exchange membrane 324 faces the interior of the storage space 213 and is configured to electrolyze water vapor outside the storage space 213 to produce hydrogen ions and oxygen. The proton exchange membrane 324 is configured to transport hydrogen ions from the anode plate 322 to the cathode plate 323. In other words, the deoxidation assembly 320 has at least four layers: from outside to inside, the anode plate 322, the proton exchange membrane 324, the cathode plate 323, and the mother plate 321. During the electrolysis process, the cathode plate 323 consumes oxygen in the storage space 213 on the one hand, and on the other hand, the water vapor generated therefrom can also increase the humidity in the storage space 213 , thereby improving the freshness preservation effect of the storage device 200 .

[0049] The chemical reaction formulas of the anode plate 322 and the cathode plate 323 are:

[0050] Anode plate: 2H2O→O2+4H + +4e -

[0051] Cathode plate: O2+4H + +4e - →2H2O

[0052] In this embodiment, the deoxidizer assembly 320 may further include two elastic plates 325 disposed outside the anode plate 322. Each elastic plate 325 is a thin rectangular plate with a hollowed-out center portion. The position and shape of the hollowed-out portion match the position and shape of the notch 521 in the motherboard 321 to allow gas to pass through. Fan screw holes 524 are provided near the vertices of the hollowed-out portions for screwing the fan assembly 330 of the deoxidizer and moisture permeability assembly 300 to the deoxidizer assembly 320. Motherboard screw holes 525 are also provided at the edges of the elastic plates 325. The position and number of the motherboard screw holes 525 match the position and number of the internal screw holes 522 in the motherboard 321, thereby screwing the multi-layer structure of the deoxidizer assembly 320 to the motherboard 321.

[0053] In some optional embodiments, the deoxidizer assembly 320 further includes a diffusion layer and at least one gasket 326. The diffusion layer is located between the anode plate 322 and the proton exchange membrane 324, and between the cathode plate 323 and the proton exchange membrane 324. The diffusion layer is made of a platinum-plated titanium mesh, which facilitates electrical conductivity and allows for water vapor diffusion. The gaskets 326 are located between the mother plate 321 and the cathode plate 323. Each gasket 326 is a thin rectangular ring with an outer ring the same size as the cathode plate 323 and the anode plate 322. Each gasket 326 is made of an elastic material to buffer the compressive forces between adjacent layers.

[0054] Figure 13 yes Figure 10 A schematic exploded view of the fan assembly 330 is shown. The fan assembly 330 is arranged in the first accommodating chamber 311, above the deoxidation assembly 320, that is, on the side of the anode plate 322 facing away from the proton exchange membrane 324, and is configured to promote the formation of an airflow blowing toward the side of the deoxidation assembly 320 facing away from the storage space 213 to provide water vapor to the deoxidation assembly 320. The fan assembly 330 includes a fan 331 and a fan frame 332. In this embodiment, the fan 331 can be a miniature axial flow fan, whose rotating shaft is perpendicular to the anode plate 322, and is used to blow water vapor outside the storage space 213 toward the anode plate 322. Since the reactant of the anode plate 322 is water vapor, the anode plate 322 needs to be continuously replenished with water so that the electrolysis reaction can continue. When deoxidizer assembly 320 is activated, the control circuit supplies power to cathode plate 323 and anode plate 322, simultaneously activating fan 331. Fan 331 blows air toward anode plate 322, simultaneously blowing water vapor from the air toward anode plate 322 to provide reactants. Because the temperature inside refrigerator 10 is generally low, the storage compartment has a relatively humid atmosphere, containing a significant amount of water vapor. Therefore, fan 331 ensures that the air within the storage compartment provides sufficient reactants for anode plate 322, eliminating the need for a separate water source or water delivery device for deoxidizer assembly 320.

[0055] The fan 331 and the deoxidation component 320 are arranged together in the first accommodating chamber 311, which shortens the distance between the fan 331 and the deoxidation component 320 and improves the air supply efficiency of the fan 331. After the fan 331 is turned on, it can quickly provide the deoxidation component 320 with the water vapor required for the electrolysis reaction, which is beneficial to improving the electrolysis efficiency of the deoxidation component 320 and achieving rapid oxygen reduction.

[0056] The fan frame 332 is used to fix and support the fan 331. The fan frame 332 is arranged on the side of the fan 331 facing the anode plate 322. For example, it can be arranged between the fan 331 and the elastic plate 325 of the deoxidation component 320. The fan 331 can be fixed to the fan frame 332 by screwing. The air supply area of ​​the fan 331 faces the circular opening 531 in the middle of the fan frame 332 and can blow the air flow into the interior of the deoxidation component 320 and blow it to the anode plate 322. The fan frame 332 can fix and support the fan 331 to prevent the fan 331 from shaking during operation. At the same time, it can also form a certain distance between the fan 331 and the elastic plate 325 to facilitate gas circulation. The fan frame 332 is further provided with fan frame screw holes 532 , the position and number of which match the position and number of the fan screw holes 524 , so that the fan frame 332 can be fixed above the deoxidizer assembly 320 by screwing.

[0057] The side of the fan rack 332 facing away from the deaerator assembly 320 is used to fix the fan 331, and the side facing the deaerator assembly 320 is screwed and fixed to the deaerator assembly 320. The fan rack 332 has the function of fixing and supporting the fan 331, and also has the function of connecting the deaerator assembly 320. Its dual fixing function integrates the deaerator assembly 320 and the fan 331 into one, and makes the fan 331 close to the deaerator assembly 320, providing a structural basis for shortening the distance between the fan 331 and the deaerator assembly 320.

[0058] Figure 14 yes Figure 3 A schematic exploded view of a moisture permeable membrane assembly 340 for the storage device 200 of the refrigerator 10 is shown. The moisture permeable membrane assembly 340 is disposed between the dewatering area 430 and the support plate 310 and within the second accommodating cavity 312 of the support plate 310. The moisture permeable membrane assembly 340 is configured to allow water vapor within the storage space 213 to permeate and escape. The moisture permeable membrane assembly 340 includes a moisture permeable membrane 341 and a moisture permeable bottom plate 342.

[0059] The moisture-permeable membrane 341 is configured to allow water vapor within the storage space 213 to slowly permeate and be discharged to the outside of the storage space 213, thereby maintaining the humidity within the storage space 213 within an appropriate range and preventing condensation or dripping due to excessive moisture within the space. In this embodiment, the moisture-permeable membrane 341 may be a pervaporation membrane having a hydrophilic layer and a hydrophobic layer. The side of the hydrophilic layer facing away from the hydrophobic layer is exposed above the dewatering area 430, i.e., facing the dewatering area 430, and the side of the hydrophobic layer facing away from the hydrophilic layer faces away from the dewatering area 430. Water vapor within the storage space 213 can permeate through the moisture-permeable membrane 341 and be discharged to the outside of the storage space 213. While the moisture-permeable membrane 341 allows water vapor to pass through, it also blocks the permeation of other gases, preventing gas exchange between the inside and outside of the storage space 213.

[0060] The shape of the moisture-permeable membrane 341 is adapted to the shape of the bottom wall of the second accommodating cavity 312, and can just close the second accommodating cavity 312. The closed space formed by the moisture-permeable membrane 341 and the support plate 310 can block the gas exchange between the dewatering area 430 and the outside of the closed space. Therefore, setting the moisture-permeable membrane 341 between the dewatering area 430 and the support plate 310 can prompt the storage device 200 to maintain a relatively closed state, which is conducive to maintaining a good fresh-keeping atmosphere and improving the fresh-keeping effect.

[0061] The moisture-permeable bottom plate 342 is positioned against the bottom of the moisture-permeable membrane 341 and above the multiple pillars 431. Specifically, the multiple pillars 431 support the moisture-permeable bottom plate 342, which in turn supports the moisture-permeable membrane 341. The dual support structure formed by the multiple pillars 431 and the moisture-permeable bottom plate 342 prevents the moisture-permeable membrane 341 from deforming due to gravity. If the moisture-permeable membrane 341 deforms, a gap will appear between it and the sidewalls of the second accommodating chamber 312, preventing the moisture-permeable membrane 341 and the support plate 310 from forming a closed space, thereby reducing the freshness preservation effect of the storage device 200. The moisture-permeable bottom plate 342 is also provided with an array of through-holes 540. The position and size of these through-holes 540 match those of the through-holes 530 in the bottom wall of the second accommodating chamber 312, allowing gas escaping from the dewatering area 430 to pass through.
