Description

Technical Field

[0001] This application relates to the field of refrigeration technology, such as a drawer assembly and a refrigeration device. Background Technology

[0002] With the upgrading of the refrigerator consumer market, high-end and large refrigerators are increasingly favored by consumers. However, as refrigerator capacity increases, consumers have raised new demands for food storage and preservation, namely, adding drawers with freezing and humidity control functions in the freezer compartment to meet the high-humidity storage environment for certain meat rolls, ready-to-eat foods, and some pre-prepared dishes. Drawers with freezing and humidity control functions prevent cold air from directly blowing onto food during the refrigeration process and have a moisture-permeable membrane component for humidity control, maintaining food in a high-humidity environment, thus effectively preventing food from drying out and losing nutrients.

[0003] However, the humidifier drawers in related technologies that have a food preservation function can only be applied to the refrigerator compartment. When food is frozen in a refrigerator, its color and flavor often change due to drying and oxidation.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0006] This disclosure provides a drawer assembly and a refrigeration device. The humidity in the storage space is regulated by a moisture-permeable membrane, and negative ions are released by a negative ion layer applied to the moisture-permeable cover. This changes the air conditions in the storage space enclosed by the drawer body, reduces the oxidation characteristics of the air in the storage space, and uses the reducing properties of negative ions to inhibit oxidation reactions while maintaining the humidity in the storage space.

[0024] The humidity in the storage space is regulated by a moisture-permeable membrane, and negative ions are released by a negative ion layer applied to the moisture-permeable cover.

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0045] Combination Figures 1 to 4As shown, this embodiment of the present disclosure provides a drawer assembly, including a drawer body 10 and a moisture-permeable cover 20. The drawer body 10 encloses a storage space 101; the moisture-permeable cover 20 is disposed on the drawer body 10, and the side facing the storage space 101 is coated with a negative ion layer 30. The moisture-permeable cover 20 covers the drawer body 10, making the storage space 101 defined by the drawer body 10 a relatively enclosed space. This prevents the airflow from the vents of the refrigeration equipment from directly entering the drawer and acting on the surface of the food, causing serious moisture loss and affecting the taste and quality of the food. The moisture-permeable cover has a perforated portion, and includes a moisture-permeable membrane disposed in the perforated portion. The moisture-permeable membrane is located above the storage space to regulate the humidity within the storage space.

[0046] In addition, a negative ion layer 30 is coated on the side of the permeable cover 20 facing the storage space 101. Negative ions are released through the negative ion layer 30 to generate negative oxygen ions in a reduced state, as well as other related negative ions generated by their interaction with water. This changes the air conditions in the storage space 101, reduces the oxidation characteristics of the air in the storage space 101, and uses the reducing properties of negative ions to inhibit the oxidation reaction, while maintaining the humidity in the storage space 101.

[0047] By constructing a perforated portion 201 on the permeable cover, it is convenient to install the permeable membrane 40 together with the permeable cover. The permeable cover 20 regulates the humidity within the storage space 101 through the permeable membrane 40.

[0048] The moisture-permeable cover is located above the storage space 101. Water vapor in the storage space 101 moves upward. When the humidity difference on both sides of the moisture-permeable membrane 40 reaches a preset value, some water vapor passes through the moisture-permeable membrane 40 and is discharged outside the storage space 101, thereby achieving the purpose of moisture permeation and humidity regulation.

[0049] The drawer assembly provided in this embodiment regulates the humidity in the storage space through a moisture-permeable membrane and releases negative ions through a negative ion layer applied to the moisture-permeable cover, thereby changing the air conditions in the storage space enclosed by the drawer body, reducing the oxidation characteristics of the air in the storage space, inhibiting oxidation reactions by utilizing the reducing properties of negative ions, and maintaining the humidity in the storage space; thus solving the problem of changes in the color and flavor of food caused by drying and oxidation during frozen food storage.

[0050] Optionally, the negative ion layer 30 includes tourmaline. Tourmaline possesses two important properties: pyroelectricity and piezoelectricity. Based on these two effects, when temperature and pressure fluctuate, the spontaneous polarization of tourmaline causes oppositely polarized charges to accumulate on the two end faces of the crystal axis, thereby generating a large electrostatic voltage along the tourmaline crystal axis. This electrostatic potential difference is sufficient to ionize the air, generating free electrons. In this process, the main components of the air are nitrogen (78.09%) and oxygen (20.95%). Because nitrogen is very stable and has a much lower electron affinity than oxygen, most of the free electrons generated by the ionization of air are captured by oxygen, forming negative oxygen ions. Negative oxygen ions are mainly generated by oxygen in the air acquiring a free electron. Due to their free charge, negative ions exhibit reducing chemical properties. In addition, tourmaline is the only mineral with a permanent electrode, known as a "natural battery." This is due to the natural polarity of tourmaline, thus enabling it to permanently release negative ions.

[0051] Optionally, the moisture-permeable membrane 40 has a three-layer structure: a hydrophobic layer, a hydroconductive layer, and a hydrophilic layer. The pore size of the moisture-permeable membrane 40 is above a certain humidity threshold and can be adjusted automatically according to the humidity level. For example, based on the inherent characteristics of the moisture-permeable membrane 40, it actively permeates moisture to the outside when the humidity is above 85%; when the relative humidity is below 80%, it stops permeating moisture to the outside to prevent the food from becoming too damp.

[0052] For example, the moisture-permeable membrane 40 has a three-layer structure, which is hydrophobic relative to the inner surface of the drawer when the relative humidity is above 80%, the middle layer (i.e., the layer with a nanoporous structure) is hydrophilic, and the layer away from the inner surface of the drawer is hydrophilic.

[0053] To protect the moisture-permeable membrane 40, non-woven fabric can be added to both sides of the membrane and the perimeter can be sealed with plastic to ensure that the moisture-permeable membrane 40 is protected from external damage.

[0054] Optionally, a ventilation section is formed between the moisture-permeable cover 20 and the drawer body 10. Under natural convection conditions, the ventilation section ensures that the temperature inside and outside the drawer is consistent.

[0055] Exemplarily, at least a first ventilation section and a second ventilation section are formed between the breathable cover 20 and the drawer body 10 in the front-to-back direction. Airflow flows into the drawer body 10 through the first ventilation section and exits from the second ventilation section. The first ventilation section is an air inlet, and the second ventilation section is an air outlet. The first ventilation section may be located at the back of the drawer assembly (i.e., the side near the air outlet), but it may also be located at the front of the drawer assembly. When the first ventilation section is located at the back of the drawer assembly, the second ventilation section is located at the front of the drawer assembly; conversely, when the first ventilation section is located at the front of the drawer assembly, the second ventilation section is located at the back of the drawer assembly.

[0056] With the first ventilation section located at the front of the drawer assembly, i.e., air enters at the front of the drawer assembly, the air outlet has a large air volume and high air velocity. The second ventilation section is the air outlet, and the airflow from the air outlet creates a negative pressure zone at the second ventilation section, allowing cold air to flow through the lower surface of the moisture-permeable cover 20 at a faster speed and exit from the second ventilation section. In addition, it can also accelerate the reduction of humidity inside the drawer.

[0057] With the first ventilation section located at the back of the drawer assembly, air enters from the back and exits from the front. The airflow from the vent can flow directly into the drawer through the first ventilation section and then exit from the second ventilation section. Similarly, the airflow from the vent is faster, allowing it to quickly exit from the second ventilation section, preventing cold air from blowing directly onto the surface of the food inside the drawer and affecting its freshness.

[0058] When the first ventilation section is constructed on the top of the moisture-permeable cover 20 or the drawer body 10, the first ventilation section may be multiple ventilation holes or a through ventilation slot. When the first ventilation section is constructed between the moisture-permeable cover 20 and the drawer body 10, the first ventilation section may be a gap, seam, etc. formed between the moisture-permeable cover 20 and the drawer body 10.

[0059] Optionally, the second ventilation section is constructed and formed between the moisture-permeable cover 20, the top of the drawer body 10, or between the moisture-permeable cover 20 and the drawer body 10.

[0060] When the second ventilation section is constructed on the top of the moisture-permeable cover 20 or the drawer body 10, the second ventilation section may be multiple ventilation holes or a through ventilation slot. When the second ventilation section is constructed between the moisture-permeable cover 20 and the drawer body 10, the second ventilation section may be a gap, seam, etc. formed between the moisture-permeable cover 20 and the drawer body 10.

[0061] It should be noted that the specific locations of the first ventilation section and the second ventilation section can be determined according to the actual situation, and are not limited to the same component (i.e., the top of the moisture-permeable cover plate 20 or the drawer body 10), and both are formed between the moisture-permeable cover plate 20 and the drawer body 10.

[0062] Optionally, the moisture-permeable cover 20 further includes: an inner cover 202 facing the storage space 101; and an outer cover 203 facing away from the storage space 101; wherein the perforated portion of the inner cover is correspondingly provided with the perforated portion of the outer cover, and the moisture-permeable membrane is located between the inner cover and the outer cover.

[0063] The inner cover plate 202 and the outer cover plate 203 clamp the moisture-permeable membrane 40 to improve the stability of the moisture-permeable membrane 40. Especially when a large amount of water vapor accumulates on the side of the moisture-permeable membrane 40 facing the storage space 101, the moisture-permeable membrane 40 can be prevented from bending downward under the action of the gravity of water droplets.

[0064] Optionally, the inner cover plate and / or the outer cover plate may have multiple grids at the perforated portion to support the moisture-permeable membrane.

[0065] The inner cover plate 202 and / or the outer cover plate 203 are provided with multiple grid plates 204 at the perforated portion 201. These not only support the moisture-permeable membrane 40 but also guide water vapor. Thus, the guide surface formed on the grid plate 204 increases the flow of water vapor and also guides the condensate formed on the side of the moisture-permeable membrane 40 facing the storage space 101, thereby preventing water vapor and condensate from freezing on the inner cover plate 202 and the inner side of the moisture-permeable membrane 40, effectively reducing frost buildup.

[0066] Optionally, the grid 204 of the inner cover plate 202 and the outer cover plate 203 is inclined, so that the surface of the grid 204 is inclined.

[0067] When the moisture-permeable cover 20 is installed over the drawer body 10, the water vapor inside the drawer body 10 flows upward along the surface of the grid 204 of the inner cover 202. During the flow, the water droplets carried in the water vapor condense into condensate after contacting the surface of the grid 204, and then slide downward along the inclined surface of the grid 204 and drip into the drawer body 10. This not only reduces the discharge of water vapor from the drawer, but also prevents water vapor from frosting on the surface of the grid 204 of the inner cover 202, thus avoiding blockage and affecting the flow of water vapor.

[0068] Since the moisture-permeable cover 20 indirectly cools the food inside the drawer, and the outside air is cooler than the inside, when the humidity inside the drawer exceeds the set level, the moisture released through the moisture-permeable membrane 40 will condense on the surface of the grid plate 204 at the inner cover 202, forming condensate. Because the grid plate 204 is angled, the condensate flows downwards along the slope, preventing condensation and freezing on its surface. Furthermore, the grid plate 204 faces the moisture-permeable membrane 40, allowing moisture to flow along its surface and guiding the condensate away.

[0069] Optionally, the negative ion layer 30 is applied to the surface of the grid plate 204 facing the storage space 101.

[0070] The negative ion layer 30 is applied to the surface of the grille 204 facing the storage space 101. The negative ions released by the negative ion layer 30 act on the storage space 101, inhibiting and sterilizing the food in the storage space 101, thereby changing the air conditions in the storage space 101 enclosed by the drawer body 10, reducing the oxidation characteristics of the air in the storage space 101, using the reducing properties of negative ions to inhibit the oxidation reaction, and maintaining the humidity in the storage space 101.

[0071] Optionally, a negative ion layer 30 is applied to the surface of the inner cover 202 facing the storage space 101. The negative ions released by the ion layer act on the storage space 101, inhibiting and sterilizing the food inside the storage space 101, thereby changing the air conditions within the storage space 101 enclosed by the drawer body 10, reducing the oxidizing properties of the air inside the storage space 101, using the reducing properties of negative ions to inhibit oxidation reactions, and maintaining the humidity inside the storage space 101.

[0072] Optionally, the negative ion layer 30 is applied to the side of the breathable membrane 40 facing the storage space 101.

[0073] Applying the negative ion layer 30 to the side of the breathable membrane 40 facing the storage space 101 not only allows the negative ions released by the negative ion layer 30 to act within the storage space 101, but also purifies the moisture passing through the breathable membrane 40. For example, negative ions can neutralize and adsorb harmful substances such as dust, viruses, and bacteria in the moisture, causing them to settle, thereby purifying the moisture and preventing it from affecting the air quality of the space where the drawer components are located, thus achieving the purpose of preventing odor transfer.

[0074] In addition, negative ions have antibacterial and bactericidal functions, and can continuously induce negative air ions and release far-infrared rays, so as to achieve the effect of sterilizing and inhibiting the water vapor that passes through the moisture-permeable membrane 40 and improving air cleanliness.

[0075] Optionally, a negative ion layer 30 may be applied to part or all of the surface of the grid 204 facing the storage space 101.

[0076] The surface of the grid plate 204 of the storage space 101, i.e., the surface of the grid plate 204 located on the inner cover plate 202, is coated with a negative ion layer 30. Users can selectively control the application area and thickness of the negative ion layer 30 according to their actual needs. For example, if food is stored in sections within the storage space 101, the application range and thickness of the negative ion layer 30 can be selected differently depending on the type of food.

[0077] Optionally, the side of the moisture-permeable membrane 40 facing the storage space 101 is constructed with a protruding structure to increase the coating area of ​​the negative ion layer 30.

[0078] When the negative ion layer 30 is applied to the moisture-permeable membrane 40, the protruding structure constructed on the side of the moisture-permeable membrane 40 facing the storage space 101 can expand the application area of ​​the negative ion layer 30, thereby increasing the contact area between the negative ion layer 30 and water vapor, and thus improving the purification, antibacterial and bactericidal effects on water vapor.

[0079] Optionally, the surface of the grid 204 facing the storage space 101 is constructed with a protruding structure to increase the coating area of ​​the negative ion layer 30.

[0080] When the negative ion layer 30 is applied to the surface of the grid plate 204, the protruding structure constructed on the surface of the grid plate 204 facing the storage space 101 can expand the application area of ​​the negative ion layer 30, thereby increasing the contact area between the negative ion layer 30 and water vapor, and thus improving the purification, antibacterial and bactericidal effects on water vapor. In addition, the protruding structure can also guide the water vapor.

[0081] Optionally, the number of grids 204 in the inner cover plate 202 is less than or equal to the number of grids 204 in the outer cover plate 203.

[0082] Optionally, the end of the grid plate 204 of the inner cover plate 202 is rounded. This facilitates the guidance of water vapor.

[0083] Optionally, the drawer assembly also includes a metal plate 50, disposed at the bottom of the drawer body 10, opposite to the negative ion layer 30, to accelerate the flow of negative ions.

[0084] A metal plate 50 is placed at the bottom of the drawer body 10. The metal plate 50 is connected to a positive power source to attract negative ions to diffuse towards the bottom of the drawer, thereby accelerating the diffusion speed of negative ions and improving the purification, antibacterial, and sterilization effects of negative ions on the air in the storage space 101.

[0085] Alternatively, the metal plate 50 may be located on the inside or outside of the bottom wall of the drawer body 10.

[0086] Alternatively, the metal plate 50 may also be provided on the side of the drawer body 10.

[0087] Combination Figures 1 to 4As shown in the figure, this disclosure provides a refrigeration device, including the drawer assembly provided in the above embodiment. The drawer assembly includes a drawer body 10 and a moisture-permeable cover 20. The drawer body 10 encloses a storage space 101; the moisture-permeable cover 20 is disposed on the drawer body 10, and the side facing the storage space 101 is coated with a negative ion layer 30; wherein, the moisture-permeable cover has a perforated portion, and the moisture-permeable cover includes a moisture-permeable membrane disposed in the perforated portion, the moisture-permeable membrane being located above the storage space for regulating the humidity in the storage space. The moisture-permeable cover 20 covers the drawer body 10, making the storage space 101 defined by the drawer body 10 a relatively closed space. In this way, the airflow blown out of the vent in the refrigeration device can be prevented from directly entering the drawer and acting on the surface of the food, causing serious moisture loss from the food and affecting the taste and quality of the food.

[0088] In addition, a negative ion layer 30 is coated on the side of the permeable cover 20 facing the storage space 101. Negative ions are released through the negative ion layer 30 to generate negative oxygen ions in a reduced state, as well as other related negative ions generated by their interaction with water. This changes the air conditions in the storage space 101, reduces the oxidation characteristics of the air in the storage space 101, and uses the reducing properties of negative ions to inhibit the oxidation reaction, while maintaining the humidity in the storage space 101.

[0089] The refrigeration equipment provided in this embodiment regulates the humidity in the storage space through a moisture-permeable membrane and releases negative ions through a negative ion layer applied to the moisture-permeable cover, thereby changing the air conditions in the storage space enclosed by the drawer body, reducing the oxidation characteristics of the air in the storage space, inhibiting the oxidation reaction by utilizing the reducing properties of negative ions, and maintaining the humidity in the storage space; thus solving the problem of changes in the color and flavor of food caused by drying and oxidation during frozen food storage.

[0090] Refrigeration equipment can be refrigerators, freezers, or wine cabinets, etc.
