Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of refrigeration equipment, in particular to a humidity adjusting and fresh-keeping module, a drawer assembly and a refrigeration equipment. BACKGROUND
[0002] When fruits and vegetables are stored in refrigeration equipment, most of them need a high humidity environment. In the prior art, most refrigerators obtain a high humidity environment through sealing, humidifying and the like. However, ultrasonic humidification is prone to condensation, causing fruits and vegetables to rot and deteriorate, which is not conducive to fresh-keeping; sealing is prone to cause water vapor produced by fruits and vegetables through transpiration and respiration to be enriched, and when temperature fluctuation occurs, water vapor condensation will occur on the cold surface, forming condensation, which will promote the rotting of fruits and vegetables, which is not conducive to fresh-keeping. Therefore, the sealed fruit and vegetable drawer needs to be designed to be moisture permeable.
[0003] At present, the industry moisture permeable design is mostly a high-molecular polyethylene moisture permeable film assembly, the moisture permeable aperture and the moisture permeable amount of which are fixed and cannot be changed according to the change of the humidity in the fruit and vegetable storage space. This may lead to condensation when the humidity in the fruit and vegetable storage space is too high and the moisture permeable amount is not enough, and to continuous permeation of water vapor when the humidity in the fruit and vegetable storage space is too low, which makes it difficult to play a moisturizing role. On the other hand, the industry moisture permeable scheme only focuses on the humidity dimension and ignores the physiological metabolism of fruits and vegetables. The physiological metabolism of fruits and vegetables produces ethylene, a ripening component, which is difficult to discharge in a sealed drawer, further promoting the aging of fruits and vegetables, leading to problems such as lignification, yellowing and rotting of fruits and vegetables. SUMMARY
[0004] The purpose of the present application is to provide a humidity adjusting and fresh-keeping module, a drawer assembly and a refrigeration equipment to solve the problem of poor storage and fresh-keeping effect of fruits and vegetables in the related art.
[0005] To this end, in a first aspect, the present application provides a humidity adjusting and fresh-keeping module, comprising a mounting box and an active humidity control film and a catalytic ethylene remover contained in the mounting box.
[0006] The active humidity control film comprises a high-molecular fiber layer and a water-absorbing material layer.
[0007] The humidity adjusting and fresh-keeping module has the functions of adjusting humidity and fresh-keeping. The humidity adjusting function is mainly provided by the active humidity control film. The high molecular fiber has crystalline regions and amorphous regions, and the high molecular fiber (for example, carbon nanofiber) belongs to a partially crystalline high molecular material. When the amorphous regions absorb water vapor molecules, swelling occurs, and a large number of micropores are formed on the surface of the high molecular fiber, which allows water vapor molecules to permeate, achieving the purpose of moisture permeability. The water absorbing material layer contains water absorbing material. When the relative humidity in the space is low, the hydrophilic groups of the water absorbing material combine with water vapor molecules in the form of hydrogen bonds to form a stable water film on the surface of the water absorbing material, blocking the pores on the surface of the water absorbing material. At the same time, the high molecular fiber layer has a low water content, and the surface micropores are closed to prevent water vapor molecules in the space from permeating, thereby achieving the purpose of moisture retention. When the relative humidity in the space is high, the hydrophilic groups in the water absorbing material layer are saturated with water, and water vapor enters the high molecular fiber layer under the action of pressure difference. The crystalline regions of the high molecular fiber layer absorb water and swell to form micropores for moisture permeability. Thus, the active humidity control film achieves the function of adjusting the humidity in the space.

[0043] To solve the technical problem that the preservation effect of the refrigerator drawer in the prior art is not ideal, an embodiment of the present application provides a humidity regulating and preservation module for a drawer of a refrigeration device.
[0044] In some embodiments of the present application, a humidity-controlling and fresh-keeping module is provided, which comprises a mounting box, and an active humidity-controlling film and a catalytic ethylene remover accommodated in the mounting box.
[0045] The active humidity-controlling film comprises a high-molecular fiber layer and a water-absorbing material layer.
[0046] The humidity-controlling and fresh-keeping module has the functions of humidity adjustment and fresh-keeping. The humidity-controlling function is mainly provided by the active humidity-controlling film. The high-molecular fiber is composed of thousands of linear long-chain macromolecules, some of which are arranged in order, i.e. crystalline regions, and some of which are arranged in disorder, i.e. amorphous regions. The high-molecular fiber (e.g. carbon nanofiber) belongs to a partially crystalline high-molecular material. When the amorphous regions absorb water vapor molecules, swelling occurs, and a large number of micropores are formed on the surface of the high-molecular fiber, which allows water vapor molecules to permeate, achieving the purpose of moisture permeation. The water-absorbing material layer contains water-absorbing materials. When the relative humidity in the space is low, the hydrophilic groups of the water-absorbing materials combine with water vapor molecules in the form of hydrogen bonds, forming a stable water film on the surface of the water-absorbing materials, blocking the pores on the surface of the water-absorbing materials. At the same time, the high-molecular fiber layer has a low water content, and the surface micropores are closed, avoiding the penetration of water vapor molecules in the space, achieving the purpose of moisture retention. When the relative humidity in the space is high, the hydrophilic groups in the water-absorbing material layer are saturated with water, and water vapor quickly enters the high-molecular fiber layer under the push of the pressure difference. The amorphous regions of the high-molecular fiber layer swell and form micropores for moisture permeation. Thus, the active humidity-controlling film achieves the function of adjusting the humidity in the space.
[0047] The appropriate humidity is conducive to fresh-keeping, and the catalytic ethylene remover can catalytically decompose ethylene, thereby avoiding the phenomenon that the high concentration of ethylene causes the fruits and vegetables to be over-ripened.
[0048] In some embodiments, the high-molecular fiber can comprise at least one selected from the group consisting of inorganic high-molecular fiber and organic polymer fiber. In some embodiments, the high-molecular fiber can be selected from carbon nanofiber. Carbon nanofiber (CNF) is a fibrous nanocarbon material curled from multiple layers of graphite sheets, with a diameter of generally 10 nm to 500 nm and a length distribution of 0.5 μm to 100 μm.
[0049] In some embodiments, the water-absorbing material layer comprises a water-absorbing material; and the water-absorbing material comprises at least one selected from the group consisting of carboxymethyl cellulose (CMC), hydroxyethyl cellulose, carboxymethyl cellulose, and cellulose xanthate.
[0050] In some embodiments, the active humidity-controlling film further comprises a base layer, and the base layer is a paper base layer.
[0051] When the base layer is included in the active humidity control film, the high polymer fiber layer and the water absorbing material layer can be arranged on the base layer. The base layer can improve the mechanical strength of the active humidity control film and prolong the service life of the product. When a paper base layer is used, the paper base layer itself has certain water absorption and water retention properties, which can further improve the humidity control effect.
[0052] In some embodiments, the paper base layer can be prepared by adding wood pulp cotton to the raw paper pulp. The addition of wood pulp cotton can further improve the water retention properties.
[0053] In some embodiments, the paper base layer contains at least one of a wet strength agent, a dry strength agent, and an antibacterial agent as an additive. In some embodiments, the wet strength agent includes at least one selected from polyethyleneimine (PEI), urea-formaldehyde resin (UF), melamine-formaldehyde resin (MF), polyamide-epichlorohydrin resin (PAE), and dialdehyde starch (DAS); the dry strength agent includes at least one selected from modified starch, polyacrylamide, and chitosan; and the antibacterial agent includes at least one selected from 5-chloro-2-methyl-4-isothiazolin-3-one, 2-methyl-4-isothiazolin-3-one, 1,2-benzisothiazolin-3-one, 2-bromo-2-nitro-1,3-propanediol, pentachlorophenol, and 8-hydroxyquinolinone.
[0054] By adding the above additives to the paper base layer, the corresponding properties can be improved. For example, the addition of a wet strength agent and / or a dry strength agent can improve the tensile strength of the active humidity control film and prolong the service life of the product. The addition of an antibacterial agent can endow the active humidity control film with antibacterial properties. The amount of the above additives can be adjusted according to actual needs.
[0055] In some embodiments, the paper base layer contains both polyethyleneimine and an antibacterial agent; for example, both polyethyleneimine and 8-hydroxyquinolinone.
[0056] Polyethyleneimine is a cationic aliphatic polymer containing a large number of primary, secondary, and tertiary amines. The polycations contained therein can negatively attract bacteria and microorganisms, and when used in combination with an antibacterial agent, the antibacterial properties can be synergistically improved.
[0057] In some embodiments, the active humidity control film further includes a protective layer, and the material of the protective layer includes non-woven fabric. For example, the protective layer can be arranged on the outermost side of the active humidity control film. In some embodiments, the active humidity control film includes a base layer, a high polymer fiber layer, a water absorbing material layer, and non-woven fabric arranged in sequence.
[0058] In some embodiments, the catalytic ethylene removal agent includes a metal catalyst and a porous carrier.
[0059] When the porous carrier and the metal catalyst are combined, the porous carrier can adsorb ethylene molecules, and then the ethylene molecules are catalytically degraded into small molecules such as carbon dioxide under the action of the metal catalyst. Therefore, the combination of the two can improve the efficiency of removing ethylene.
[0060] In some embodiments, the metal catalyst comprises at least one selected from the group consisting of Pt, Pd, Au, Ag, Cu, Ag, Mn and oxides thereof. For example, it can be selected from an Ag / Mn catalyst.
[0061] In some embodiments, the porous carrier comprises at least one selected from the group consisting of silicon oxide, silicate, activated carbon, aluminum silicate, aluminosilicate, aluminum oxide and the like. In some embodiments, the porous carrier is selected from a 13X type molecular sieve, which belongs to an alkali metal aluminosilicate, has a pore size of 10A, and is suitable for adsorbing molecules larger than 3.64A and smaller than 10A. In some embodiments, a 13X type molecular sieve with a particle size of 1.5-2.5mm is used.
[0062] Reference Figure 1 In some embodiments, the mounting box 100 comprises a shell 101, a cover 102 and an end cap 103; the cover 102 and the end cap 103 are both provided with a plurality of through holes;

[0065] The end cap 103 is provided on the opening of the second recess; a second accommodating cavity is formed between the end cap 103 and the second recess; and the active humidity control film is accommodated in the second accommodating cavity.
[0066] When the above structure is used, the active humidity control film and the catalytic ethylene remover can be in full contact with water vapor, ethylene molecules and the like in the space (for example, a vegetable drawer), and can play the functions of humidity control and ethylene removal.
[0067] In some embodiments, the side surface of the first recess is provided with at least one through hole.
[0068] By providing a through hole on the side surface of the first recess, the contact area of the catalytic ethylene remover with the gas in the space (for example, a vegetable drawer) can be increased, thereby facilitating the improvement of the ethylene removal efficiency.
[0069] In the embodiments of the second aspect of the present application, a preparation method of the humidity control and preservation module is provided, comprising providing a mounting box, and arranging an active humidity control film and a catalytic ethylene remover.
[0070] In some embodiments, the method for preparing the active moisture-controlling membrane includes: providing a paper base layer, for example, a paper base layer prepared by a wet papermaking process; spraying polymer fibers onto the paper base layer to form polymer fibers, and spraying an absorbent material to form an absorbent material layer; and laminating a nonwoven fabric, thereby obtaining the active moisture-controlling membrane. In some embodiments, the paper base layer contains wood pulp cotton and / or other additives, which are added to the base wood pulp during the wet papermaking process.
