Description

Technical Field

[0001] This application relates to the field of refrigeration equipment technology, such as a storage basket and a freezer. Background Technology

[0002] When discussing refrigeration preservation technology, for direct-cooling refrigeration units, placing a sealed container inside containing ingredients like tender beef can maintain high humidity, which is beneficial for keeping the beef moist. However, this often presents a challenge: beef, being rich in moisture, experiences rapid moisture condensation on its surface when exposed to dry, low-temperature environments due to the low partial pressure of water vapor in the external cold air. This moisture quickly condenses into frost or ice crystals below zero degrees Celsius, not only damaging the beef's original tender texture but also making it difficult to achieve the desired preservation effect.

[0003] In contrast, air-cooled freezers are characterized by continuous internal air circulation. However, when a sealed container containing fresh beef is placed inside, the result is similar to that of a direct-cooling freezer—moisture seepage and frost formation still occur on the surface of the beef. Furthermore, attempting to create holes in the sealed container to promote air circulation, while reducing internal frost formation, accelerates the evaporation of moisture from the beef's surface, causing the beef to dry out prematurely and significantly diminishing its flavor.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] Freezers have limited space and function, and most can only cool the space.

[0006] 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.

[0070] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0076] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0077] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0078] Combination Figures 1 to 28 As shown in the illustration, this embodiment of the present disclosure provides a freezer, including a cabinet body 50 and a storage basket. The storage basket is placed inside the cabinet body 50, helping users to store different types of food separately, facilitating management and retrieval, and preventing cross-contamination between foods. Using the storage basket allows for more efficient use of the freezer's vertical space, increasing storage capacity. The storage basket is typically easy to disassemble and clean, helping to maintain hygiene inside the freezer. Furthermore, the storage basket prevents food from directly contacting the bottom of the freezer, thus avoiding moisture absorption due to condensation.

[0079] The cabinet 50 has an air outlet 501 on its inner wall. A storage basket is located within the cabinet 50 and has a first airflow path structure and a second airflow path structure with different airflow directions. The airflow direction of the first airflow path structure matches the airflow direction of the air outlet 501. The design of the first and second airflow path structures helps the cold air blown from the air outlet 501 of the cabinet 50 to flow into the storage basket, ensuring the freezing effect on the food inside the basket.

[0080] The different airflow directions of the first and second airflow structures help disperse and circulate the cold air flowing into the storage basket, ensuring uniform freezing of food, preventing localized overcooling, and improving the overall freezing effect. Because of the different airflow directions of the first and second airflow structures, the airflow direction of the second airflow structure is at least intersecting with that of the first airflow structure. The airflow direction of the first airflow structure matches the airflow direction of the outlet 501, meaning that the airflow from the outlet 501 flows directly into the first airflow structure.

[0081] The freezer provided in this embodiment of the present disclosure has airflow blowing out from the air outlet 501 into the first air path structure. The airflow direction of the first air path structure and the second air path structure are different, which helps to disperse and circulate the cold air flowing into the storage basket, thereby ensuring that the food is frozen evenly, avoiding local overcooling, and improving the overall freezing effect.

[0082] Optionally, the storage basket includes a humidifying box 10 for storage, and the first air duct structure includes a first ventilation section 101, which is constructed on the side wall of the humidifying box 10 and arranged around it; wherein a portion of the first ventilation section 101 is arranged corresponding to the air outlet 501 of the cabinet 50.

[0083] The first ventilation section 101 is arranged around the humidification box 10. The airflow blown out from the air outlet 501 flows into the humidification box 10 through the first ventilation section 101 and then flows out. This not only freezes the food in the humidification box 10, but also blows away the moisture in the humidification box 10 quickly to prevent frost from forming.

[0084] A portion of the first ventilation section 101 is configured to correspond to the air outlet 501 of the cabinet 50, which helps the airflow from the air outlet 501 to flow into the humidifying box 10 and facilitates the airflow inside the humidifying box 10 to flow out through other areas of the first ventilation section 101.

[0085] Optionally, the first ventilation section 101 is located at the upper part of the humidification box 10. This avoids the first ventilation section 101 being too low and blocked by the food inside the humidification box 10, thereby affecting the inflow and outflow of air.

[0086] Optionally, the first ventilation section 101 includes a plurality of first ventilation holes 1011, which are evenly spaced to facilitate uniform air delivery and uniform stress distribution on the humidification box 10.

[0087] Optionally, the first ventilation hole 1011 can be a hole-shaped structure or a polygonal structure, but is not limited to the above two structures. Any conventional structure that can achieve ventilation can be considered as the first ventilation hole 1011.

[0088] Optionally, the second air duct structure includes: a third ventilation section 102, constructed on the side wall of the humidification box 10, with opposite ventilation arrangement; wherein the third ventilation section 102 is arranged to avoid the side wall where the air outlet 501 of the cabinet 50 is located.

[0089] The third ventilation section 102 is arranged for ventilation on opposite sides and avoids the side wall where the air outlet 501 of the cabinet 50 is located. In this way, the airflow from the air outlet 501 of the cabinet 50 flows directly from the first ventilation section 101 into the humidifying box 10, while the circulating airflow inside the cabinet 50 flows into the humidifying box 10 through the third ventilation section 102. The two airflows have different directions and are arranged vertically.

[0090] The third ventilation section 102 includes multiple third ventilation holes 1021. The multiple third ventilation holes 1021 are evenly spaced, which is conducive to uniform air supply and uniform stress on the entire humidification box 10.

[0091] Optionally, the third ventilation hole 1021 can be a hole-shaped structure or a polygonal structure, but is not limited to the above two structures. Any conventional structure that can achieve ventilation can be considered as the third ventilation hole 1021.

[0092] For example, the humidifying box 10 has a cuboid structure, with its four side walls being a first side wall, a second side wall, a third side wall, and a fourth side wall, respectively. The first and third side walls are width side walls, while the second and fourth side walls are length side walls. The first side wall corresponds to the air outlet 501 of the cabinet 50. At this time, the third ventilation section 102 is located on the second and fourth side walls.

[0093] The table below shows the humidity inside the humidification box 10 when the third ventilation section 102 is located on the length sidewall and the width sidewall.

[0094]

[0095] The experimental data above shows that when the third ventilation section 102 is located on the long side wall, the humidity inside the humidification box 10 is higher than when the third ventilation section 102 is located on the wide side wall. Therefore, when the third ventilation section 102 is located on the long side wall, avoiding the air outlet 501 of the cabinet 50 (i.e., not directly connected to the air outlet 501), a better humidification effect can be achieved.

[0096] Optionally, the storage basket further includes: a moisture-permeable cover 20, disposed in the humidification box 10 and located between the first ventilation section 101 and the third ventilation section 102; wherein the first ventilation section 101 is located above the third ventilation section 102 and parallel to the third ventilation section 102.

[0097] The humidifying box 10 with a moisture-permeable cover 20 can control the humidity of the stored food and has a moisturizing function.

[0098] The moisture-permeable cover 20 is located between the first ventilation section 101 and the third ventilation section 102, with the first ventilation section 101 located above the third ventilation section 102. Through the first ventilation section 101 corresponding to the air outlet 501, the airflow from the air outlet 501 quickly flows into the humidifying box 10 and passes above the moisture-permeable cover 20, which can blow away the water vapor that permeates from the moisture-permeable cover 20, thereby preventing water vapor from frostling on the moisture-permeable cover 20.

[0099] When the permeable cover 20 is placed over the top opening of the humidifying box 10, ventilation inside the humidifying box 10 is maintained through the third ventilation section 102. Furthermore, the third ventilation section 102 is positioned to avoid the air outlet 501, thereby preventing the third ventilation section 102 from rapidly blowing away moisture inside the humidifying box 10 and affecting its moisturizing effect. In addition, the third ventilation section 102, located below the permeable cover 20, also helps prevent frost from condensing below the permeable cover 20.

[0100] The first ventilation section 101 and the third ventilation section 102 are arranged in parallel. Although the airflow directions are different, the airflow layers are parallel, which helps the humidification box 10 to be subjected to uniform force and reduces vibration caused by uneven airflow.

[0101] If the third ventilation section 102 is set vertically, it is impossible to ensure that the airflow inside the humidification box 10 is uniform. Especially after placing fresh food at room temperature inside the humidification box 10, the hot and humid air rises and is prone to localized frost formation on the top surface.

[0102] Optionally, the moisture-permeable cover plate 20 includes: a first clamping plate 201 having a plurality of first moisture-permeable holes 2011; a second clamping plate 202 having a plurality of second moisture-permeable holes 2021 and being detachably connected to the first clamping plate 201; and a moisture-permeable membrane 203 located between the first moisture-permeable holes 2011 and the second moisture-permeable holes 2021; wherein the first moisture-permeable holes 2011 and the second moisture-permeable holes 2021 are correspondingly arranged.

[0103] The moisture-permeable membrane 203 is fixed by the first clamp 201 and the second clamp 202, and in conjunction with the moisture-permeable membrane 203, the humidity of the internal environment of the humidification box 10 is regulated more effectively.

[0104] The second clamp 202 faces the moisturizing space inside the moisturizing box 10, and the first clamp 201 is located above the second clamp 202. Moisture inside the moisturizing box 10 passes through the second moisture-permeable hole 2021 to the moisture-permeable membrane 203. Some moisture passes over the moisture-permeable membrane 203 and moves through the first moisture-permeable hole 2011 to the top of the moisture-permeable cover 20.

[0105] Optionally, the second clamping plate 202 is provided with a clamping groove, and the moisture-permeable membrane 203 passes through the clamping groove. This helps to further improve the stability of the installation and fixation of the moisture-permeable membrane 203.

[0106] Working principle of the moisture-permeable membrane 203: The moisture-permeable membrane 203 has a humidity threshold. When the humidity inside the moisturizing box 10 is greater than the humidity threshold, the moisture-permeable membrane 203 will permeate excess water vapor molecules to the outside of the moisturizing box 10, i.e., to the side of the moisture-permeable membrane 203 with lower humidity. When the humidity inside the moisturizing box 10 is less than or equal to the humidity threshold, the moisture-permeable structure of the moisture-permeable membrane 203 remains closed, the permeation mode is not activated, and the humidity on both sides of the moisture-permeable membrane 203 will not affect each other.

[0107] For example, the moisture-permeable membrane can be a moisture-sensing and moisturizing membrane, which achieves the effects of moisturizing and permeability by adjusting the intensity of the moisture permeability.

[0108] When the internal humidity is high and the external humidity is low, the internal adsorption is strong, the external dissipation is strong, and the conduction is strong, resulting in a moisture-permeable film. When the internal humidity is low, the adsorption and conduction are weak, resulting in a moisturizing effect. High humidity leads to strong adsorption, while low humidity leads to weak adsorption. A large concentration difference or high humidity enhances conduction, while a small concentration difference or low humidity weakens conduction. Low humidity leads to strong dissipation, while high humidity leads to weak dissipation.

[0109] Optionally, the ratio of the distance from the center of the third ventilation hole of the third ventilation section to the bottom wall of the humidification box 10 to the depth of the humidification box 10 is 0.7 to 0.95. This not only prevents the third ventilation hole from being blocked by food in the humidification space when it is too low, thus affecting the internal ventilation effect and causing frost to easily form on the permeable cover 20; but also prevents the ventilation band between the third ventilation hole and the permeable cover 20 from being too narrow when it is too high, creating a wall-hugging effect. This would cause the rising water vapor to be carried away by the airflow due to excessively high airflow velocity, thus affecting the humidity control effect.

[0110] Using the permeable membrane 203 as the top reference, the current depth of the humidifying box 10 is 125mm. The distance from the center of the third ventilation hole to the bottom wall of the humidifying box 10 is approximately 112mm, accounting for 90% of the overall depth. If this distance is too low, the food inside the humidifying space will easily block the airflow, resulting in poor internal ventilation, maintaining a high humidity level, and even making it easier for frost to form on the permeable cover 20. If the distance is too high, the ventilation band between the third ventilation hole and the permeable cover will be narrow, easily forming a wall-adhering effect, increasing the airflow velocity, and making it easier for rising water vapor to be carried out of the humidifying box 10 by the airflow, thus preventing the permeable membrane 203 from achieving its intended effect. Therefore, the distance from the center of the third ventilation hole to the bottom wall of the humidifying box 10 should generally be maintained at 70-95% of the depth of the humidifying box 10, that is, the ratio of the distance from the center of the third ventilation hole to the bottom wall of the humidifying box 10 to the depth of the humidifying box 10 is 0.7-0.95. Experimental data are shown in the table below.

[0111] ratio 10％ 20％ 30％ 40％ 50％ 60％ 70％ 80％ 90％ 100％ humidity 90％ 90％ 90％ 90％ 87％ 85％ 83％ 82％ 82％ 80％

[0112] Optionally, the ventilation area of ​​the first ventilation hole 1011 corresponding to the air outlet 501 of the cabinet 50 partially overlaps with the ventilation area of ​​the air outlet 501. This increases airflow efficiency and makes the distribution of cold air more uniform while ensuring that frost does not condense above the permeable cover 20. Additionally, it prevents excessive cooling caused by excessive airflow above the permeable cover 20; the partial overlap of the ventilation areas reduces the amount of cooling required.

[0113] Optionally, the ratio of the distance from the midpoint of the storage basket to the top of the cabinet 50 to the depth of the cabinet 50 is 0.1 to 0.3. In this way, the storage basket is located in the upper area of ​​the cabinet 50, which can ensure sufficient airflow and wind speed across the humidification box 10 and the moisture-permeable cover 20, thereby controlling the humidity inside the humidification box 10 to meet the user's needs.

[0114] For ease of description, the distance from the midpoint of the storage basket's vertical depth to the top of the cabinet 50 is defined as H0, and the depth of the cabinet 50 is defined as H1. According to the experiment, the lower the storage basket is within the cabinet 50, the worse the moisture retention effect. Experimental data are shown in the table below.

[0115] H_0 / H_1 (%) Air volume (L / min) humidity(%) 10 18 83 30 15 78 50 13 73 70 16 71 90 17 67

[0116] Optionally, the ratio of the distance from the midpoint of the storage basket's horizontal width to the side wall of the cabinet 50 to the horizontal width of the cabinet 50 is 0.1–0.3 or 0.7–0.9. This can be understood as dividing the cabinet 50 into three equally spaced areas along its length: a left-side area, a middle area, and a right-side area. Installing the storage basket in the left-side and right-side areas not only ensures the humidity requirements of the storage basket but also facilitates user access to food within the cabinet 50, avoiding obstruction by the storage basket.

[0117] For ease of description, we define the distance from the midpoint of the storage basket's horizontal width to the side wall of the cabinet 50 as W0, and the length of the inner liner's side wall in the same direction as W1. According to the experiment, the humidity of the storage basket is higher at the left and right ends of the cabinet 50, and lower in the middle. The experimental data are shown in the table below.

[0118] W0 / W_1(%) Air volume (L / min) humidity(%) 20 13 83 40 21 75 60 16 79 80 12 86

[0119] Optionally, the storage basket has an overlapping section that overlaps the edge of the top opening of the cabinet 50 for fixation. By overlapping the storage basket with the top opening edge of the cabinet 50, it not only allows for separate storage from other food items inside the cabinet 50, facilitating management and retrieval, but also makes full use of the upper space, more effectively utilizing the vertical space of the freezer and increasing storage capacity. Furthermore, the storage basket also fully utilizes the airflow from the air outlet 501 inside the cabinet 50, working in conjunction with the humidification box 10 and the moisture-permeable cover 20 to prevent frost and ice buildup on the surface of the moisture-permeable cover 20.

[0120] This disclosure also provides a freezer, including: a cabinet body 50 and a storage basket. The cabinet body 50 has an opening at the top; the storage basket is disposed on the upper part of the cabinet body 50, and the edge of the storage basket overlaps the edge of the opening of the cabinet body 50; wherein, the storage basket includes at least a humidifying box 10, a quick-freezing box 30 and an expansion box 40, the humidifying box 10 and the quick-freezing box 30 are stacked longitudinally, the expansion box 40 is partially surrounded by the humidifying box 10 laterally, and the expansion box 40 and the humidifying box 10 are movable relative to each other.

[0121] The freezer provided in this embodiment enhances the functionality of storage baskets by incorporating a humidifying box 10, a quick-freezing box 30, and an extension box 40. This optimizes the space utilization of traditional single-function storage baskets, improving efficiency. During use, the quick-freezing box 30 can be easily moved vertically, and the extension box 40 can be pulled horizontally, making it convenient to use. Furthermore, the storage baskets overlap the top opening edge of the cabinet body 50 via an overlapping section. This not only allows for separate storage from other food items within the cabinet body 50, facilitating management and retrieval, but also fully utilizes the upper space, making more efficient use of the freezer's vertical space and increasing storage capacity.

[0122] The inner circumference of the humidifying box 10 is limited to a humidifying space, the inner circumference of the quick-freezing box 30 is limited to a quick-freezing space, and the outer circumference of the expansion box 40 is limited to an expansion space with the side wall of the humidifying box 10 after being pulled out a preset distance from the humidifying box 10.

[0123] Optionally, the quick-freezing box 30 is partially or entirely embedded in the humidifying box 10, and the extension box 40 has a semi-open structure and is partially enclosed outside the humidifying box 10.

[0124] The quick-freezing box 30 is partially or completely embedded in the humidifying box 10, which not only helps to improve the stability of the connection between the quick-freezing box 30 and the humidifying box 10, but also reduces part of the airflow passing over the moisture-permeable cover 20 in the humidifying box 10, thereby ensuring the moisture control effect of the moisture-permeable cover 20.

[0125] With the quick-freezing box 30 fully embedded inside the humidifying box 10, the closure of the freezer door and the cabinet body 50 can be avoided due to the quick-freezing box 30.

[0126] The semi-open structure of the expansion box 40 can be understood as having an opening at the top and an opening on one side wall. The expansion box 40 is fitted onto the outside of the humidifying box 10 through the opening in the side wall, thereby achieving the purpose of the expansion box 40 partially enclosing the outside of the humidifying box 10. For example, one side wall of the expansion box 40 in the longitudinal direction is open. That is, the expansion box 40 has only one side wall in the longitudinal direction.

[0127] Optionally, it also includes: a moisture-permeable cover 20, which is disposed at the bottom of the quick-freezing box 30 and located inside the humidity box 10.

[0128] The quick-freezing box 30 is placed on the moisturizing box 10 from top to bottom, and the moisture-permeable cover 20 is placed at the bottom of the quick-freezing box 30. When the quick-freezing box 30 is lifted from the moisturizing box 10, the moisture-permeable cover 20 can also be removed from the moisturizing box 10, making it convenient for users to directly put and take out food in the moisturizing box 10.

[0129] Optionally, the side wall of the humidifying box 10 is provided with a first ventilation section 101, the side wall of the quick-freezing box 30 is provided with a second ventilation section 301 that matches the first ventilation section 101, and the side wall of the expansion box 40 is provided with a fourth ventilation section 401 that matches the first ventilation section 101; when the humidifying box 10, the quick-freezing box 30 and the expansion box 40 are stacked and stored, the first ventilation section 101, the second ventilation section 301 and the fourth ventilation section 401 are connected to each other.

[0130] When the first ventilation section 101, the second ventilation section 301 and the fourth ventilation section 401 are stacked, they directly correspond to the air outlet 501 of the cabinet 50, and the airflow flows through the fourth ventilation section 401, the first ventilation section 101 and the second ventilation section 301 in sequence.

[0131] Optionally, the second ventilation section 301 is located at the bottom of the quick-freezing box 30. The second ventilation section 301 includes a plurality of second ventilation holes 3011, which are evenly spaced to facilitate uniform stress distribution on the quick-freezing box 30. Optionally, the second ventilation holes 3011 can be perforated or polygonal, but are not limited to these two structures. Any conventional structure that enables ventilation can be considered a second ventilation hole 3011. Optionally, the second ventilation holes 3011 match the first ventilation holes 1011. Optionally, the second ventilation section 301 is arranged around the circumferential sidewall of the quick-freezing box 30 and corresponds to the first ventilation section 101.

[0132] Optionally, the fourth ventilation section 401 includes a plurality of fourth ventilation holes 4011, which are evenly spaced to facilitate uniform stress distribution on the expansion box 40. Optionally, the fourth ventilation holes 4011 can be perforated or polygonal, but are not limited to these two structures. Any conventional structure that enables ventilation can be considered a fourth ventilation hole 4011. Optionally, the fourth ventilation holes 4011 match the first ventilation holes 1011 to reduce wind resistance and ensure airflow. Optionally, the fourth ventilation section 401 is arranged around the circumferential sidewall of the expansion box 40 and corresponds to the first ventilation section 101.

[0133] Optionally, the overlap rate between the height of the first ventilation section 101 and the corresponding air outlet 501 is 10% to 50%. This ensures that the interlayer space is frost-free.

[0134] Optionally, the side wall of the humidifying box 10 has a third ventilation section 102, and the side wall of the expansion box 40 has a fifth ventilation section 402 that matches the third ventilation section 102; when the humidifying box 10 and the expansion box 40 are stacked and stored together, the third ventilation section 102 and the fifth ventilation section 402 are connected accordingly. In this way, by connecting the third ventilation section 102 and the fifth ventilation section 402 accordingly, the side wall of the expansion box 40 can be prevented from obstructing the third ventilation section 102 and affecting airflow.

[0135] Optionally, the fifth ventilation section 402 includes a plurality of fifth ventilation holes 4021.

[0136] Optionally, the height difference between the center of the third ventilation section 102 and the center of the air outlet 501 of the cabinet 50 is 20-40mm. This avoids frost formation and ensures effective humidity control.

[0137] Optionally, the side wall of the humidifying box 10 has a first ventilation groove 103, the side wall of the quick-freezing box 30 has a second ventilation groove 302 that matches the first ventilation groove 103, and the side wall of the expansion box 40 has a third ventilation groove 403 that matches the first ventilation groove 103; when the humidifying box 10, the quick-freezing box 30 and the expansion box 40 are stacked and stored, the first ventilation groove 103, the second ventilation groove 302 and the third ventilation groove 403 are connected accordingly.

[0138] The airflow from the air outlet 501 flows into the quick-freezing box 30 and the humidifying box 10 through the first ventilation slot 103 and the second ventilation slot 302, cooling the quick-freezing space of the quick-freezing box 30 and freezing the food inside. The first ventilation slot 103 and the second ventilation slot 302 are designed to ensure smooth airflow and reduce air resistance.

[0139] The expansion box 40 is provided with a third ventilation slot 403, which enables the first ventilation slot 103, the second ventilation slot 302 and the third ventilation slot 403 to be connected when the humidification box 10, the quick-freezing box 30 and the expansion box 40 are stacked and stored together, thereby ensuring the airflow of the quick-freezing space.

[0140] Optionally, the first ventilation slot 103, the second ventilation slot 302, and the third ventilation slot 403 have the same structure. Optionally, the first ventilation slot 103 has a polygonal or circular structure. For example, the first ventilation slot 103 is rectangular. Optionally, the plurality of first ventilation slots 103 are inclined and evenly spaced. Similarly, the plurality of second ventilation slots 302 are inclined and evenly spaced. The plurality of third ventilation slots 403 are inclined and evenly spaced.

[0141] Optionally, the height of the area corresponding to the second ventilation slot 302 of the quick-freezing box 30 and the air outlet 501 of the cabinet 50 is 30% to 80% of the height of the air outlet 501. In simpler terms, the overlap rate between the ventilation areas of the second ventilation slot 302 and the corresponding air outlet 501 is 30% to 80%.

[0142] For example, with an overlap rate of 50%, a 3kg load stored in the quick-freezing space can be cooled from 25℃ to -18℃ in just 2.8 hours, which translates to 13kg / 12h. In contrast, the average freezing capacity of the insulated box 10 is 11kg / 12h, representing an 18% improvement. For detailed comparative testing, see [link to test]. Figure 28.

[0143] The improvement in freezing capacity of more than 10% mentioned in this article is considered effective, indicating that the lower limit of the overlap rate is 30%. Subsequently, as the overlap rate increases, although the freezing capacity increases consistently, an excessively high overlap rate will occupy space for other functions, such as the humidification box 10. Therefore, an overlap rate of 30% to 80% between the second ventilation slot 302 and the corresponding air outlet 501 is preferable.

[0144] Optionally, the top edge of the humidifying box 10 is bent outward to form a first overlapping portion 104, the top edge of the quick-freezing box 30 is bent outward to form a second overlapping portion 303, and the top edge of the expansion box 40 is bent outward to form a third overlapping portion 404; wherein, the second overlapping portion 303 overlaps above the first overlapping portion 104, and the first overlapping portion 104 overlaps above the third overlapping portion 404; the first overlapping portion 104, the second overlapping portion 303, and the third overlapping portion 404 form a hanging ear structure to overlap and install on the opening edge of the cabinet 50.

[0145] From top to bottom, the second overlapping part 303, the first overlapping part 104, and the third overlapping part 404 are sequentially overlapped to form a hanging ear structure, which overlaps the edge of the opening of the cabinet 50. In this way, not only can the installation stability between the storage basket and the cabinet 50 be guaranteed, but also the assembly stability between the humidification box 10, the quick-freezing box 30, and the expansion box 40 can be guaranteed.

[0146] Optionally, a first overlap 104 is formed on the width sidewalls of the humidifying box 10, namely the first sidewall and the third sidewall. The first sidewall and the third sidewall of the humidifying box 10 are respectively mounted to the opening edge of the cabinet 50 via the first overlap 104. Similarly, a second overlap 303 is formed on the width sidewall of the quick-freezing box 30, and a third overlap 404 is formed on the width sidewall of the expansion box 40.

[0147] Optionally, the opening edge of the cabinet 50 is constructed with a stepped structure, and the hanging ear structure is positioned and installed on the stepped structure; wherein, the length of the stepped structure is greater than the length of the hanging ear structure, so that the expansion box 40 can move along the length direction. By positioning and installing the hanging ear structure through the stepped structure, the installation position of the storage basket inside the cabinet 50 is ensured, the stability of the connection between the storage basket and the cabinet 50 is improved, and the humidity box 10 is placed in a suitable position to ensure the humidity control effect of the humidity-retaining space.

[0148] Optionally, the depth of the step structure is greater than or equal to the thickness of the lug structure. In this way, when the lug structure overlaps with the step structure, the cabinet door covers the top opening edge of the cabinet body 50, ensuring the airtightness between the cabinet door and the cabinet body 50.

[0149] This disclosure provides a storage basket, including a moisture-retaining box 10, a quick-freezing box 30, and a moisture-permeable cover 20.

[0150] The humidifying box 10 has an opening at the top and a first ventilation section 101 on its side wall; the quick-freezing box 30 is located at the top of the humidifying box 10 and has a second ventilation section 301 on its side wall; the moisture-permeable cover 20 is located at the bottom of the quick-freezing box 30 and inside the humidifying box 10; wherein the quick-freezing box 30 is embedded inside the humidifying box 10, and the second ventilation section 301 is connected to the first ventilation section 101, and the airflow passing through the first ventilation section 101 and the second ventilation section 301 flows above the moisture-permeable cover 20.

[0151] The storage basket provided in this embodiment enhances the functionality of the storage basket by incorporating the humidifying box 10, the quick-freezing box 30, and the moisture-permeable cover 20 located between them. This optimizes the space utilization of the original single-function storage basket and improves its efficiency. The airflow passing through the first ventilation section 101 and the second ventilation section 301 flows above the moisture-permeable cover 20, which can promptly blow away the water vapor that has passed through the moisture-permeable cover 20, preventing frost from forming on the upper surface of the moisture-permeable cover 20, thereby ensuring the humidity control effect of the humidifying space inside the humidifying box 10.

[0152] Optionally, the moisture-permeable cover 20 is detachably connected to the bottom of the quick-freezing box 30 for easy replacement and maintenance. A space is defined between the moisture-permeable cover 20 and the quick-freezing box 30. The space can be understood as a ventilation zone. Moisture in the humidifying space permeates from the moisture-permeable cover 20 to the space. The space is connected to the first ventilation section 101 and the second ventilation section 301. Airflow flows into the space through the first ventilation section 101 and the second ventilation section 301, blowing the moisture away from the top of the moisture-permeable cover 20, thereby preventing frost from forming on the upper surface of the moisture-permeable cover 20 and thus affecting the subsequent humidity control effect.

[0153] Optionally, a first ventilation section 101 is arranged around the circumferential sidewall of the humidification box 10. Airflow flows in and out through the first ventilation section 101, quickly blowing moisture away from above the moisture-permeable cover 20. A second ventilation section 301 is arranged around the circumferential sidewall of the quick-freezing box 30. The second ventilation section 301 matches the first ventilation section 101 to avoid affecting the airflow and air velocity of the first ventilation section 101.

[0154] Optionally, the side wall of the humidifying box 10 is also constructed with a third ventilation section 102, through which airflow flows below the permeable cover plate 20. The airflow flows into the humidifying space of the humidifying box 10 from the third ventilation section 102 and flows below the permeable cover plate 20, which not only delivers cool air into the humidifying box 10, but also blows away droplets or water vapor accumulated below the permeable cover plate 20, preventing frost and ice formation, thus affecting the subsequent humidity control effect.

[0155] Optionally, the first ventilation slot 103 and the third ventilation section 102 are respectively located on different side walls of the humidification box 10. The third ventilation section 102 is positioned to avoid the air outlet 501 of the cabinet 50, so as to prevent the air volume and air speed from being too fast, thereby blowing away the water vapor in the humidification space and affecting the humidification effect; while the first ventilation slot 103 is positioned corresponding to the air outlet 501 to ensure the air volume and air speed, thereby ensuring the quick-freezing effect on the food in the quick-freezing box 30.

[0156] Optionally, the bottom wall of the quick-freezing box 30 is higher than the second ventilation section 301 to avoid obstructing the second ventilation section 301. The bottom wall of the quick-freezing box 30 has protruding ribs 306. In this way, the ribs 306 separate the bottom wall of the quick-freezing box 30 from the stored food, preventing the food inside the quick-freezing box 30 from sticking to the bottom wall of the quick-freezing box 30, affecting the airflow at the bottom, and thus affecting the quick-freezing effect.

[0157] Optionally, the bottom wall of the quick-freezing box 30 has a bottom ventilation groove, which is connected to the interlayer space defined between the moisture-permeable cover plate 20 and the quick-freezing box 30.

[0158] Moisture that permeates from the moisture-permeable cover 20 into the interlayer space can continue to move upwards and through the bottom ventilation slots to the quick-freezing space, thereby increasing the humidity of the food in the quick-freezing space. In addition, when the cold air flows through the interlayer space, some of the cold air diffuses to the bottom ventilation slots, which can cool and quick-freeze the food at the bottom of the quick-freezing box 30, thereby improving the overall quick-freezing efficiency of the quick-freezing box 30.

[0159] Optionally, the moisture-permeable cover 20 includes: a first clamping plate 201 with a positioning part 2012; a second clamping plate 202 with a snap-fit ​​part 2022 and detachably connected to the first clamping plate 201; and a moisture-permeable membrane 203 disposed between the first clamping plate 201 and the second clamping plate 202; wherein, the bottom of the quick-freezing box 30 is provided with a positioning mating part 304 and a snap-fit ​​mating part 305, the positioning part 2012 of the first clamping plate 201 is connected to the positioning mating part 304, and the snap-fit ​​part 2022 of the second clamping plate 202 is connected to the snap-fit ​​mating part 305.

[0160] The first clamping plate 201 and the second clamping plate 202 are detachably connected. Then, the first clamping plate 201 is connected to the positioning mating part 304 of the quick-freezing box 30 through the positioning part 2012, so as to realize the positioning and installation of the first clamping plate 201 and the quick-freezing box 30. After the position of the first clamping plate 201 is determined, it is connected to the quick-freezing box 30 through the snap-fit ​​part 2022 of the second clamping plate 202 and the snap-fit ​​mating part 305 of the quick-freezing box 30, so as to realize the detachable connection between the moisture-permeable cover plate 20 and the quick-freezing box 30.

[0161] The moisture-permeable cover 20 is doubly positioned by the positioning part 2012 and the snap-fit ​​part 2022 to ensure its positioning and installation with the quick-freezing box 30. In addition, it can also avoid reverse assembly of the moisture-permeable cover 20, which would affect the moisture permeation efficiency. Among them, the first clamping plate 201 faces the bottom wall of the quick-freezing box 30.

[0162] The positioning part 2012 can be a groove structure, and the positioning mating part 304 can be a protrusion structure. Alternatively, the positioning part 2012 can be a protrusion structure, and the positioning mating part 304 can be a groove structure.

[0163] Optionally, the humidifying box 10 has a first overlapping portion 104, and the quick-freezing box 30 has a second overlapping portion 303; wherein the second overlapping portion 303 overlaps with and matches the first overlapping portion 104. The humidifying box 10 and the quick-freezing box 30 are assembled through the first overlapping portion 104 and the second overlapping portion 303, and the second overlapping portion 303 overlapping with the first overlapping portion 104 not only facilitates the handling of the quick-freezing box 30, but also allows the quick-freezing box 30 to be transported together with the humidifying box 10.

[0164] This disclosure also provides a moisturizing component, including a moisturizing box 10 and a moisture-permeable cover 20. The moisturizing box 10 with the moisture-permeable cover 20 has a moisture control function.

[0165] The humidifying box 10 has an opening at the top and at least one first ventilation section 101 and a third ventilation section 102 arranged side by side along the depth direction of the humidifying box 10 on the sidewalls; a moisture-permeable cover plate 20 is provided on the opening of the humidifying box 10 and is located between the first ventilation section 101 and the third ventilation section 102.

[0166] Using the moisturizing component provided in this embodiment, the food is placed in the moisturizing space inside the moisturizing box 10, and the moisture-permeable cover 20 is placed over the opening of the moisturizing box 10 to regulate the humidity of the moisturizing space; through the first ventilation part 101 and the second ventilation part 301, the airflow passes over the top and bottom of the moisture-permeable cover 20, and the permeable water vapor and the accumulated water vapor are quickly blown away from the moisture-permeable cover 20 to prevent the moisture-permeable cover 20 from frosting and affecting the subsequent humidity control effect.

[0167] Optionally, the third ventilation section 102 is located on two opposite side walls of the humidification box 10 for side ventilation. This controls the airflow into the humidification box 10, preventing excessive airflow that could blow away most of the moisture, thus reducing humidity and affecting the food's moisture retention. Simultaneously, the incoming cold airflow cools the food, ensuring its freezing effect.

[0168] Optionally, the moisture-permeable cover 20 is located inside the humidification box 10 and divides the internal space of the humidification box 10 into an upper cavity and a lower cavity; wherein, the first ventilation part 101 is connected to the upper cavity and the third ventilation part 102 is connected to the lower cavity.

[0169] The internal space of the humidification box 10 is divided by a moisture-permeable cover 20, allowing moisture in the lower cavity to overflow into the upper cavity through the cover 20. Airflow passing through the first ventilation section 101 blows away moisture from the upper cavity, preventing frost formation. Airflow passing through the third ventilation section 102 flows into the lower cavity, cooling the food inside. This not only ensures the freezing effect but also blows away moisture below the moisture-permeable cover 20, preventing condensation on its lower surface and thus affecting subsequent moisture penetration and humidity control.

[0170] Optionally, the side wall of the humidifying box 10 is also provided with a first ventilation groove 103, which is located above the first ventilation section 101, and the ventilation area of ​​the first ventilation groove 103 is larger than the ventilation area of ​​the first ventilation section 101.

[0171] The first ventilation slot 103 is located above the first ventilation section 101, and the ventilation area of ​​the first ventilation slot 103 is larger than that of the first ventilation section 101. This helps to enable the cold air from the first ventilation slot 103 to quickly cool the upper cavity, i.e., to quickly freeze the food. It also ensures that the cold air from the first ventilation section 101 quickly blows away the moisture on the upper surface of the moisture-permeable cover 20, preventing frost from forming on the upper surface of the moisture-permeable cover 20.

[0172] Optionally, the first ventilation slots 103 are located on two opposite side walls of the humidifying box 10 for cross-ventilation. Cross-ventilation is also known as through-flow ventilation, where air flows in from one side and out from the opposite side. This helps ensure that the airflow passes through the entire upper cavity, preventing it from flowing out in all directions, thereby ensuring the quick-freezing effect on the food inside the upper cavity.

[0173] Optionally, the first ventilation section 101 includes a plurality of first ventilation holes 1011, and the third ventilation section 102 includes a plurality of third ventilation holes 1021; wherein the first ventilation holes 1011 and the third ventilation holes 1021 located on the same side wall of the humidifying box 10 are offset or correspondingly arranged.

[0174] When the first ventilation hole 1011 and the third ventilation hole 1021 on the same side wall of the humidifying box 10 are staggered, it helps to ensure the structural strength of the side wall and improve its service life. When the first ventilation hole 1011 and the third ventilation hole 1021 on the same side wall of the humidifying box 10 are correspondingly arranged, it can make the same position of the side wall evenly stressed.

[0175] This disclosure also provides a storage basket comprising a humidifying box 10 and an expansion box 40. By pulling out the expansion box 40, the expansion box 40 can be moved relative to the humidifying box 10, thereby releasing expanded space to store more food.

[0176] The humidifying box 10 has an open top; the expansion box 40 has a semi-open structure and can partially enclose the outside of the humidifying box 10; the expansion box 40 and the humidifying box 10 can enclose a storage cavity, the volume of which is controlled by the distance between the expansion box 40 and the humidifying box 10 in the lateral movement direction.

[0177] The storage basket provided in this embodiment allows for the horizontal pulling of the extension box 40, which moves relative to the humidifying box 10, thereby adjusting the volume of the storage cavity and expanding the storage space of the basket. This not only allows for the storage of more food items but also enables the separate storage of different types of food. When expansion is not needed, the humidifying box 10 and the extension box 40 can be stacked, reducing space occupation and providing convenience to meet various user needs.

[0178] Optionally, the expansion box 40 partially encloses the outside of the moisturizing box 10 from the bottom and sides. In this way, not only is the purpose of pulling out the expansion box 40 achieved, but also when the expansion box 40 is pulled out laterally, one side wall of the moisturizing box 10 can be used as the missing side wall of the expansion box 40, that is, one side wall of the moisturizing box 10 and the expansion box 40 together enclose and form a storage cavity.

[0179] Optionally, the depth of the expansion box 40 is greater than or equal to the depth of the humidification box 10. This increases the storage capacity of the expansion box 40 when expanding the storage space, further improving the space utilization of the storage basket within the cabinet 50 and enhancing the user experience.

[0180] Optionally, the humidifying box 10 has a first overlapping portion 104, and the expansion box 40 has a third overlapping portion 404; wherein the first overlapping portion 104 and the third overlapping portion 404 are arranged in abutment. The humidifying box 10 and the expansion box 40 are assembled through the first overlapping portion 104 and the third overlapping portion 404. The humidifying box 10 and the expansion box 40 can be transported and installed as a single unit, which is convenient and quick.

[0181] Optionally, the first overlapping portion 104 is provided with a positioning groove 1041, and the third overlapping portion 404 is provided with a positioning protrusion 4041. The positioning protrusion 4041 is embedded in the positioning groove 1041 and can slide along the positioning groove 1041 to limit the movement trajectory of the extension box 40.

[0182] The first overlapping portion 104 and the third overlapping portion 404 are precisely positioned by the positioning groove 1041 and the positioning protrusion 4041, and also serve as a limiting mechanism. In particular, when the expansion box 40 is pulled out laterally to expand the space, the positioning groove 1041 and the positioning protrusion 4041 can limit the movement trajectory of the expansion box 40.

[0183] Optionally, the side wall of the extension box 40 is configured with a fifth ventilation section 402, which is correspondingly provided with the third ventilation section 102 of the humidification box 10, and the ventilation area of ​​the fifth ventilation section 402 is less than or equal to the ventilation area of ​​the third ventilation section 102.

[0184] When the expansion box 40 and the humidifying box 10 are stacked, the airflow outside the storage basket flows sequentially through the fifth ventilation section 402 and the third ventilation section 102 and flows into the humidifying box 10. When the ventilation area of ​​the fifth ventilation section 402 is smaller than that of the third ventilation section 102, the airflow into the humidifying box 10 is adjusted by the overlap between the fifth ventilation section 402 and the third ventilation section 102, thereby adjusting the humidity and cooling rate inside the humidifying box 10 to meet the storage requirements of specific food items.

[0185] With the expansion box 40 pulled out horizontally to form an expanded space, the cold air outside the storage basket flows into the expanded space through the fifth ventilation section 402, which can cool the food in the expanded space and ensure the freezing effect of the food.

[0186] Optionally, the fifth ventilation section 402 is located on the side wall of the expansion box 40 that overlaps with the humidification box 10. The fifth ventilation section 402 is provided correspondingly to the third ventilation section 102 and is located on the side wall of the expansion box 40 that overlaps with the humidification box 10, ensuring communication with the third ventilation section 102, that is, avoiding affecting the humidity control inside the humidification box 10.

[0187] This disclosure also provides a freezer, including a cabinet body 50 and a humidification box 10.

[0188] The inner side wall of the cabinet 50 has an air outlet; the humidifying box 10 is located inside the cabinet 50, the humidifying box 10 defines a humidifying space, and the side wall has a humidifying air outlet connected to the humidifying space; wherein the humidifying air outlet and the air outlet are arranged to avoid each other, and / or the plane where the humidifying air outlet is located intersects with the plane where the air outlet is located.

[0189] The refrigerator provided in this embodiment has a humidification box 10 located inside the cabinet 50 to humidify the stored food and achieve a preservation effect. By designing the humidification air vent and the air outlet to avoid each other and to have the plane of the humidification air vent intersect with the plane of the air outlet, the airflow from the air outlet can be prevented from blowing directly into the humidification space through the humidification air vent, causing water to be drawn out from the surface of the food, reducing the humidity of the food, and thus affecting the taste of the food.

[0190] Optionally, the freezer also includes a moisture-permeable cover, located on top of the humidification box 10 and above the humidification vent. This humidification vent may be equivalent to the third ventilation section 102 described herein.

[0191] Optionally, the humidifying air vent is positioned away from the air outlet to prevent the airflow from the air outlet from blowing directly onto the humidifying air vent. For example, the humidifying air vent is not positioned directly opposite the air outlet, or the edge of the humidifying air vent avoids the edge of the air outlet and the air outlet area defined therein.

[0192] Optionally, the cabinet 50 side wall is provided with an upward air supply duct, which includes multiple air outlets; wherein, the vertical distance between the air outlet adjacent to the humidifying air outlet and the humidifying air outlet is 30-40mm.

[0193] The return air vent of cabinet 50 is located at the bottom. The airflow from the air outlet on the side corresponding to the return air vent blows forward and then flows into the return air vent; while the airflow from the other air outlets flows forward and to one side before flowing into the return air vent.

[0194] In this embodiment, the humidification box 10 can be located on the side where the return air vent is located, and the humidification air vent is positioned to avoid the air outlet. The air outlet here can be the first air outlet 5011 mentioned in this document.

[0195] The humidification box 10 is located in the upper space of the cabinet 50, which facilitates assembly and improves the space utilization rate inside the cabinet 50.

[0196] The vertical distance between the air outlet and the humidifying air vent is 30-40mm. This not only ensures that the air outlet and the humidifying air vent in the humidifying space do not blow directly on each other, preventing the airflow from the outlet from directly entering the humidifying space and causing excessively low humidity; it also maintains the relative humidity in the humidifying space between 80% and 85%; and prevents frost from forming on the cooler areas such as the side wall (front side wall) of the humidifying box 10 near the upper air duct. See the figure below for relevant experimental data.

[0197]

[0198] The test data above shows that when the distance between the humidifying air vent and the adjacent air outlet is small, more dry and cold air enters the humidifying box 10 through the humidifying air vent. The humidifying space and the front wall of the humidifying box 10 are affected by this dry and cold air, resulting in lower humidity on both the front wall and the center of the humidifying space, with the front wall being more significantly affected. When the distance between the humidifying air vent and the adjacent air outlet is large, less dry and cold air enters the humidifying box 10 through the humidifying air vent. The front wall is less affected by the dry and cold air outside the humidifying box 10, resulting in a humidity close to 100%. Furthermore, the front wall is affected by the direct cold airflow, leading to a low temperature and frost formation. The center of the humidifying space can still maintain approximately 90% humidity due to the influence of the moisture-permeable membrane 203.

[0199] Therefore, the distance between the humidifying air vent and the adjacent air outlet should be maintained between 30 and 40 mm, which can maintain the humidity inside the box between 80% and 85% relative humidity, and prevent frost from forming on the cooler areas such as the front side wall.

[0200] It should be noted that the distance between the air outlet and the humidifying air outlet can be measured from the nearest edge of the two air outlets or from the center of the two air outlets.

[0201] Optionally, the edge of the air outlet is provided with guide ribs 5012 to guide the airflow; and / or, the edge of the air outlet is provided with guide ribs 5012 that are inclined upward along the airflow direction. The guide ribs ensure the flow direction of the airflow blown out of the air outlet.

[0202] Optionally, the air circulation volume of the humidification space is M = Q1 / V, and 1 ≤ M ≤ 2.5; where Q1 is the air volume inside the humidification box 10, and V is the volume of the humidification space formed inside the humidification box 10.

[0203] For example, the volume of the humidification space inside the humidification box 10 is approximately 10L. Its internal humidity is affected by two factors: first, the amount of moisture evaporated from the food itself; second, the amount of moisture removed by the combined effect of the airflow entering the humidification space and the moisture-permeable membrane 203. The amount of moisture removed by the moisture-permeable membrane 203 is considered separately. Here, we only increase the area of ​​the humidification vents to verify the effect of airflow, which is 5 / 10 / 15 / 20 / 25 / 30L / min respectively. The amount of moisture evaporated from the food itself is represented by the percentage of the volume containing ice cubes, which is 5%, 25%, 50%, 75%, and 100% respectively. The humidity at the center of the humidification space is tested.

[0204]

[0205] The test data above shows that when the air circulation volume (i.e., air volume / volume) of the moisturizing space is low, the humidity inside the moisturizing box 10 cannot be discharged in time. Due to the effect of the moisture-permeable membrane 203, the center still maintains 90%, but frost has appeared on the front side wall. When the air circulation volume of the moisturizing space is large, the humidity inside the moisturizing box 10 is low, especially when there is less food in the box.

[0206] Therefore, the air circulation rate of the moisturizing space (i.e., the ratio of airflow within the moisturizing box 10 to the volume of the moisturizing space) is ideally between 1 and 2.5. This not only maintains the moisturizing effect but also prevents frost buildup.

[0207] Optionally, the air volume Q1 in the humidification box 10 is S*F, where S is half of the total ventilation area of ​​the humidification air vents, F is the wind speed of the circulating air in the cabinet 50, and the value of F ranges from 0.05 to 0.2 m / s.

[0208] The airflow within cabinet 50 includes direct airflow and circulating airflow. Direct airflow, blown directly from the air outlet and guided by the air guide ribs 5012 and door sills, experiences minimal velocity reduction due to distance, with a velocity ranging from 0.5 to 3 m / s, and is the primary source of cooling capacity. Circulating airflow is partly dissipated by the direct airflow and partly generated by the airflow movement within the cabinet driven by the direct airflow, with a velocity ranging from 0.05 to 0.2 m / s, assisting in cooling the cabinet. The average velocity of the circulating airflow is 0.05 to 0.2 m / s. Since the velocity of the circulating airflow varies little across different locations within the cabinet, the ventilation area of ​​the vents in the humidification space largely determines the airflow entering the humidification space.

[0209] Optionally, the freezer also includes a quick-freeze box 30, positioned above the humidification box 10. The quick-freeze box 30 defines a quick-freeze space, and a quick-freeze vent connected to the quick-freeze space is provided on the side wall of the quick-freeze box 30. This quick-freeze vent can be equivalent to the second ventilation slot 302 in this document.

[0210] Optionally, some quick-freezing air vents are set to correspond to the air outlets of the cabinet 50, with a spacing of 8 to 15 mm.

[0211] To ensure effective cooling in the quick-freezing space, the distance between the quick-freezing vent and the air outlet should be as small as possible. This is because the airflow from the outlet experiences dissipation within a large space, causing its velocity to decrease. The following test results illustrate this:

[0212]

[0213] To ensure the air velocity at the quick-freezing air outlet, the maximum distance between the quick-freezing air outlet and the corresponding air outlet should be ≤15mm.

[0214] For example, the actual air outlet has an outward 5mm air guide rib 5012. In addition, considering the assembly gap, a 3mm gap is reserved. Therefore, the minimum distance between the quick-freezing air outlet and the corresponding air outlet is ≥8mm.

[0215] Optionally, the quick-freezing box 30 is located above the moisture-permeable cover, and a space is defined between the quick-freezing box 30 and the moisture-permeable cover. The side walls of the quick-freezing box 30 and / or the moisturizing box 10 are constructed with anti-frost vents communicating with the space, so that airflow flows into the space and prevents frost from forming above the moisture-permeable cover. Here, the anti-frost vents can be equivalent to the first ventilation section 101 in this document. Optionally, the anti-frost vents are correspondingly provided with the air outlet.

[0216] Optionally, the number of air circulations per minute in the quick-freezing space should be greater than 5 times, corresponding to an air volume of >12.15L / min.

[0217] This disclosure also provides a freezer, which includes a cabinet body 50 and a door body 60; a humidification box 10 is disposed inside the cabinet body 50, the humidification box 10 defines a humidification space, and the side wall is constructed with a humidification air vent communicating with the humidification space; wherein, along the depth direction of the cabinet body 50, the humidification air vent is spaced apart from the inner side wall of the door body 60 by a first preset distance.

[0218] The refrigerator provided in this embodiment has a humidification box 10 located inside the cabinet 50 to humidify the stored food and achieve a preservation effect. Along the depth direction of the cabinet 50, the humidification vent is spaced a first preset distance from the inner wall of the door 60. This prevents cold air flowing through the inner wall of the door 60 from directly entering the humidification space through the humidification vent, which would cause moisture to evaporate from the surface of the food, reducing its humidity and affecting its taste. The refrigerator not only has a freezing function but also a humidification and preservation function.

[0219] Optionally, the first preset distance between the humidifying air vent and the inner wall of the door 60 is greater than 60mm.

[0220] In practical applications, a portion of the direct airflow from the air outlet flows along the guide groove 601 on the inner wall of the door 60 towards the other side of the cabinet 50. This can be understood as the direct airflow from the air outlet flowing along the inner wall of the door 60. The air velocity varies at different distances from the inner wall of the door 60. Relevant data is shown in the table below.

[0221]

[0222] As can be seen, when the distance to the inner wall of the door 60 is greater than 55mm, the airflow velocity decreases significantly, indicating that this location is less affected by direct airflow. Therefore, designing the first preset distance between the humidifying air vent and the inner wall of the door 60 to be greater than 60mm can better ensure that the humidifying air vent avoids the influence of direct airflow from the outlet, thus ensuring the humidifying effect within the humidifying space.

[0223] It should be noted that the measurement point of the first preset distance between the humidifying air vent and the inner wall of the door 60 can be the lower edge of the humidifying air vent or the center point of the humidifying air vent.

[0224] Optionally, the inner wall of the cabinet 50 is constructed with multiple air outlets, with the humidifying air outlets and the air outlets arranged to avoid each other. This prevents cold air blown from the air outlets from directly blowing onto the humidifying air outlets and entering the humidifying space, thus avoiding affecting the humidification effect on the food inside the humidifying space.

[0225] Optionally, the freezer also includes: a quick-freezing box 30, located above the humidifying box 10, the quick-freezing box 30 defining a quick-freezing space; wherein the quick-freezing box 30 is spaced from the inner wall of the door 60 by a second preset distance.

[0226] The quick-freezing box 30 is positioned above the humidifying box 10, closer to the inner wall of the door 60. It utilizes the direct airflow passing through the inner wall of the door 60 to rapidly cool the food within the quick-freezing space, achieving the purpose of quick-freezing. To ensure smooth airflow between the cabinet 50 and the door 60, and to guarantee air circulation within the cabinet 50, the quick-freezing box 30 and the inner wall of the door 60 need to be spaced at a second preset distance. This distance ensures smooth air circulation within the cabinet 50 and also fully utilizes the cooling effect of the direct airflow passing through the inner side of the door 60, achieving rapid freezing of the food within the quick-freezing box 30.

[0227] Optionally, the second preset distance between the quick-freezing box 30 and the inner sidewall of the door 60 is less than 55mm.

[0228] Based on the experimental data above showing different wind speeds at different locations from the inner wall of the door 60, a second preset distance of less than 55mm was set between the quick-freezing box 30 and the inner wall of the door 60. This ensures smooth air circulation within the cabinet 50 and also fully utilizes the cooling effect of the direct airflow passing through the inner side of the door 60, enabling rapid freezing of the food inside the quick-freezing box 30.

[0229] It should be noted that the measurement point of the second preset distance between the quick-freezing box 30 and the inner wall of the door 60 can be the bottom wall of the quick-freezing box 30 or the center point of the quick-freezing space defined by the quick-freezing box 30.

[0230] Optionally, the side wall of the quick-freezing box 30 is provided with a quick-freezing air vent that communicates with the quick-freezing space, and the quick-freezing air vent is set corresponding to the air outlet of the cabinet 50. The cold air blown directly from the air outlet of the cabinet 50 flows into the quick-freezing space through the quick-freezing air vent, cooling the food in the quick-freezing space and achieving the purpose of quick-freezing.

[0231] Optionally, the quick-freezing box 30 is embedded in the top of the humidifying box 10, and the side wall of the humidifying box 10 is constructed with ventilation slots that match the quick-freezing air vents. In this way, the airflow blown out of the air outlet passes through the ventilation slots and flows into the quick-freezing space through the quick-freezing air vents to cool and freeze the food in the quick-freezing space.

[0232] This disclosure also provides a moisturizing component, including: a moisturizing box 10 and a moisture-permeable module.

[0233] The moisturizing box 10 has a storage space; a moisture-permeable module is provided in the moisturizing box 10 and divides the storage space into multiple moisturizing spaces; wherein, the side wall of the moisturizing box 10 is constructed with moisturizing vents that match the moisturizing spaces.

[0234] Using the moisturizing component provided in this embodiment, the storage space inside the moisturizing box 10 is divided into multiple moisturizing spaces by a moisture-permeable module. Each moisturizing space is matched with a moisturizing air vent to achieve zoned humidity control, meet diverse storage needs, and ensure the freezing and moisturizing effect in each moisturizing space.

[0235] Optionally, the moisture-permeable module includes multiple moisture-permeable covers that divide the storage space into multiple moisture-retaining spaces. These multiple moisture-retaining spaces allow for different humidity levels, thus achieving zoned humidity control.

[0236] Optionally, multiple breathable covers can be arranged side by side. This facilitates installation and allows for better determination of the volume of the moisture-retaining space, making it easier to store food.

[0237] Optionally, multiple permeable covers are arranged in parallel laterally, and / or multiple permeable covers are arranged in parallel longitudinally.

[0238] For example, in the case of three moisture-permeable covers, the three moisture-permeable covers are arranged in an upper, middle, and lower structure, and the three moisture-permeable covers and the humidification box 10 define three humidification spaces. Optionally, the performance parameters of the moisture-permeable membranes 203 of the three moisture-permeable covers are not consistent.

[0239] For example, the humidity in the lowest level moisturizing space is controlled to 85% through the cooperation of the moisturizing vents and the moisture-permeable membrane 203. Excess moisture will be conducted to the upper (middle) level moisturizing space. The volume of the middle level moisturizing space 200 is the same as that of the lowest level moisturizing space. The difference is that the moisture permeability of the moisture-permeable membrane 203 on the moisture-permeable cover above the middle level moisturizing space 200 is higher than that of the moisture-permeable membrane 203 above the lowest level moisturizing space 300. At the same time, the ventilation area of ​​the moisturizing vents corresponding to the middle level moisturizing space 200 is larger than that of the moisturizing vents corresponding to the lowest level moisturizing space 300. This is to further reduce the original humidity in the middle level moisturizing space 200, assuming the humidity in the middle level moisturizing space 200 reaches 60%; excess moisture will be conducted to the upper (top) level moisturizing space.

[0240] The uppermost moisturizing space 100 has the same volume as the lowermost moisturizing space 300 and the middle moisturizing space 200. The difference is that the moisture permeability of the moisture-permeable membrane 203 above the uppermost moisturizing space 100 is higher than that above the moisture-permeable membrane 203 in the middle moisturizing space 200. Simultaneously, the ventilation area of ​​the moisturizing vent corresponding to the uppermost moisturizing space 100 is larger than that of the moisturizing vent corresponding to the middle moisturizing space 200. This is done to further reduce the existing humidity in the uppermost moisturizing space 100, assuming the humidity in the uppermost moisturizing space 100 reaches 45%.

[0241] When dynamic equilibrium is reached, the humidity in each humidified space tends to stabilize. This does not mean that water vapor conduction does not occur, but rather that a dynamic equilibrium process is being reached.

[0242] It should be noted that the position of the three-layer moisture-retaining space is not limited to an upper, middle, and lower structure; it can also be a left, middle, and right structure, or a front, middle, and rear structure. Regardless of whether it is a left, middle, and right structure or a front, middle, and rear structure, the principle of multiple breathable covers to achieve zoned humidity control is the same as that of an upper, middle, and lower structure.

[0243] When the three humidification spaces have the same volume but use different moisture-permeable membranes 203, the area of ​​the ventilation holes will vary. The higher the relative position of the humidification space, the larger the area of ​​the corresponding humidification vent needs to be to ensure that the humidity within the humidification space is maintained within a stable range. This ensures a stepped transfer of humidity among the three humidification spaces.

[0244] Optionally, the moisture permeability of multiple breathable covers may be partially or completely the same. In this way, the humidity conditions of the humidification space corresponding to different breathable covers are different, thereby allowing the storage of ingredients with different humidity requirements, meeting different user needs, and improving the user experience.

[0245] Optionally, when multiple moisture-permeable covers are arranged horizontally in parallel, the moisture permeability of the multiple moisture-permeable covers gradually increases from bottom to top.

[0246] In this way, with multiple layers of moisture-permeable covers having different permeability rates, the bottom layer of moisture-permeable membrane 203 can conduct moisture upwards to the moisture-permeable space above, thereby humidifying the moisture-permeable space above. In this way, by using multiple layers of moisture-permeable membranes 203, the purpose of zoned humidity control can be achieved within the moisture-permeable box 10.

[0247] Optionally, the ventilation areas of multiple sets of humidifying vents that match multiple humidifying spaces may be partially or entirely the same. Humidifying vents with different ventilation areas, in conjunction with moisture-permeable covers, enable humidity control in different humidifying spaces, thereby storing ingredients with different humidity requirements, meeting diverse user needs, and enhancing the user experience.

[0248] Optionally, when multiple moisture-permeable covers are arranged horizontally in parallel, the ventilation area of ​​multiple sets of moisture-retaining air vents gradually increases from bottom to top.

[0249] In this way, even though the three moisturizing spaces have the same volume, the breathable membranes 203 used are not the same, resulting in different ventilation hole areas. The higher the relative position of the moisturizing space, the larger the area of ​​the corresponding moisturizing air vent needs to be, in order to ensure that the humidity within the moisturizing space is maintained within a stable range. This ensures a stepped transfer of humidity among the three moisturizing spaces.

[0250] This disclosure also provides a storage basket, including: a moisture-retaining box 10, a first moisture-permeable cover 20, a second moisture-permeable cover 70, and an extension box 40.

[0251] A humidifying box 10; a first moisture-permeable cover 20 disposed on the humidifying box 10 and defining a first humidifying space with the humidifying box 10; a second moisture-permeable cover 70 inserted into the humidifying box 10 and slidable; an extension box 40 that can partially enclose the outside of the humidifying box 10 and can move laterally relative to the humidifying box 10; wherein, the second moisture-permeable cover 70 is connected to the extension box 40 and can move laterally relative to the humidifying box 10 with the extension box 40; when the second moisture-permeable cover 70 and the extension box 40 are pulled out relative to the humidifying box 10, the second moisture-permeable cover 70, the extension box 40 and the humidifying box 10 define a second humidifying space.

[0252] The storage basket provided in this embodiment, with the expansion box 40 and the second moisture-permeable cover 70 combined, not only simply expands the storage space of the storage basket, but also makes the expanded storage space have a moisturizing function. When the expansion box 40 and the moisturizing box 10 are stacked, the first moisture-permeable cover 20 and the second moisture-permeable cover 70 are stacked, allowing for further adjustment based on the original target humidity of the moisturizing box 10, so as to further meet the different storage needs of users and improve the applicability and practicality of the storage basket.

[0253] When combined, the humidification box 10 and the extension box 40 are compact and do not affect the storage capacity of the freezer. When pulled apart, they form two independent humidification compartments, which can be used to store different types of food, such as different meats or fruits and vegetables. Furthermore, the humidity of the first humidification compartment can be adjusted within a certain range to meet different needs.

[0254] Optionally, the side wall of the humidification box 10 is constructed with a groove 105, and the second moisture-permeable cover 70 is slidably connected in the groove 105. This facilitates the movement of the second moisture-permeable cover 70 as the extension box 40 is pulled out. Furthermore, it improves the installation stability of the second moisture-permeable cover 70 when it is inside the humidification box 10.

[0255] Optionally, the thickness of the edge of the second moisture-permeable cover 70 that contacts the moisturizing box 10 is reduced to avoid the groove 105 opening being too large and affecting the overall structural strength of the moisturizing box 10.

[0256] Optionally, the second breathable cover 70 can be integrated with the expansion box 40. Optionally, the second breathable cover 70 and the expansion box 40 can be detachably connected.

[0257] Optionally, the first permeable cover plate 20 and the second permeable cover plate 70 are arranged in parallel. This facilitates assembly and ensures uniform airflow between the first and second permeable cover plates 20 and 70, thereby guaranteeing uniform temperature and humidity in the space between them and thus ensuring effective temperature and humidity control.

[0258] For example, the first permeable cover 20 may be located above or below the second permeable cover 70.

[0259] When the humidifying box 10 and the expansion box 40 are in the combined state, only the first humidifying space can store items. Because there are two layers of permeable membrane 203 above the first humidifying space, the resistance to water permeation is increased, resulting in a better humidifying effect, manifested in a higher relative humidity value, denoted as φ1. When the expansion box 40 and the second permeable cover 70 are pulled out from the side, a second humidifying space is formed. At this time, there is only one layer of permeable membrane 203 above the first humidifying space, reducing the resistance to water permeation. Therefore, the humidifying effect is weakened, manifested in a lower relative humidity value, denoted as φ2. Therefore, φ2 < φ1. During the process of the expansion box 40 and the second moisture-permeable cover 70 being pulled outward relative to the moisturizing box 10, a portion of the top surface of the first moisturizing space has two layers of moisture-permeable membrane 203 and a portion has one layer of moisture-permeable membrane 203. The ratio of the area occupied by the two layers of moisture-permeable membrane 203 and the area occupied by the one layer of moisture-permeable membrane 203 can be adjusted by the distance the expansion box 40 and the second moisture-permeable cover 70 are pulled out. This ratio will affect the moisturizing effect, thereby adjusting the target humidity of the first moisturizing space to a certain extent.

[0260] Optionally, the first moisture-permeable cover plate 20 and the second moisture-permeable cover plate 70 constitute a moisture-permeable assembly, and the side wall of the humidifying box 10 is provided with a first ventilation section 101 above the moisture-permeable assembly; wherein, the side wall of the extension box 40 is provided with a fourth ventilation section 401 that matches the first ventilation section 101.

[0261] The storage basket, through the first ventilation section 101 and the fourth ventilation section 401, allows the cold air of the freezer to flow over the moisture permeation component, quickly blowing away the moisture on the moisture permeation component, thereby preventing frost from forming on the moisture permeation component and thus avoiding affecting the moisture permeation effect of the moisture permeation component.

[0262] Optionally, the first moisture-permeable cover plate 20 and the second moisture-permeable cover plate 70 constitute a moisture-permeable assembly, and the side wall of the humidification box 10 is provided with a third ventilation section 102 below the moisture-permeable assembly; wherein, the side wall of the extension box 40 is provided with a fifth ventilation section 402 that matches the third ventilation section 102.

[0263] The storage basket allows cold air from the freezer to flow into the humidification box 10 and the expansion box 40 through the third ventilation section 102 and the fifth ventilation section 402, freezing the food inside the humidification box 10 and the expansion box 40. At the same time, it blows away the moisture below the moisture permeation component to prevent moisture from accumulating and freezing below the moisture permeation component, thus affecting the moisture permeation effect.

[0264] Optionally, the storage basket also includes: a quick-freezing box 30, which is located on top of the moisture-proof box 10 and defines a quick-freezing space; wherein, a sandwich space is formed between the quick-freezing box 30 and the first moisture-permeable cover plate 20 or the second moisture-permeable cover plate 70, and the sandwich space is connected to the first ventilation section 101.

[0265] When the first moisture-permeable cover 20 is located above the second moisture-permeable cover 70, a sandwich space is formed between the quick-freezing box 30 and the first moisture-permeable cover 20. The sandwich space is connected to the first ventilation section 101, so that cold air flows over the first moisture-permeable cover 20 and blows away the water vapor that permeates from the first moisture-permeable cover 20 quickly, preventing frost from forming on the top of the first moisture-permeable cover 20, thereby avoiding affecting the moisture permeability of the first moisture-permeable cover 20.

[0266] When the first moisture-permeable cover 20 is located below the second moisture-permeable cover 70, a sandwich space is formed between the quick-freezing box 30 and the second moisture-permeable cover 70. The sandwich space is connected to the first ventilation section 101, so that cold air flows over the second moisture-permeable cover 70 and blows away the water vapor that permeates from the second moisture-permeable cover 70 quickly, preventing frost from forming on the top of the second moisture-permeable cover 70, thereby avoiding affecting the moisture permeability of the second moisture-permeable cover 70.

[0267] Optionally, when the first moisture-permeable cover 20 is located above the second moisture-permeable cover 70, the first moisture-permeable cover 20 and the quick-freezing box 30 can be detachably connected or integrated. In this way, when the quick-freezing box 30 is removed from the top of the humidifying box 10, the first moisture-permeable cover 20 can be removed together, thus making it convenient for the user to put in and take out the food in the humidifying box 10.

[0268] Optionally, the side wall of the quick-freezing box 30 is constructed with a quick-freezing vent, which can be connected to the first ventilation section 101. In this way, the quick-freezing vent not only quickly freezes the food inside the quick-freezing box 30, but also, by connecting with the first ventilation section 101, increases the airflow above the moisture-permeable component, thereby accelerating the removal of moisture from above the moisture-permeable component and preventing frost from forming on the moisture-permeable component, which would affect the moisture-permeable effect.

[0269] Optionally, the first moisture-permeable cover 20 and the second moisture-permeable cover 70 each include: a first clamping plate 201 with multiple first moisture-permeable holes 2011; a second clamping plate 202 with multiple second moisture-permeable holes 2021, and detachably connected to the first clamping plate 201; and a moisture-permeable membrane 203 located between the first and second moisture-permeable holes 2011 and 2021; wherein the first and second moisture-permeable holes 2011 and 2021 are correspondingly arranged. The overall structural design of the first moisture-permeable cover 20 and the second moisture-permeable cover 70 is the same. However, the moisture permeability of the moisture-permeable membrane 203 of the first moisture-permeable cover 20 and the moisture permeability of the moisture-permeable membrane 203 of the second moisture-permeable cover 70 may be the same or different. When the two are different and the moisturizing box 10 and the extension box 40 are pulled out relative to each other, the humidity control of the first moisturizing space and the second moisturizing space is different, thus achieving zoned humidity control and improving storage versatility.

[0270] This disclosure also provides a moisturizing component, including: a moisturizing box 10 and a moisture-permeable cover.

[0271] A moisture-permeable cover is disposed on the moisturizing box 10, defining a moisturizing space with the moisturizing box 10; wherein, the moisture-permeable cover includes a clamping plate and a moisture-permeable membrane 203 connected to each other, the area of ​​the moisture-permeable membrane 203 and the volume of the moisturizing space satisfy a first condition, and / or, the area of ​​the moisture-permeable membrane 203 and the area of ​​the clamping plate satisfy a second condition.

[0272] Using the humidification component provided in this embodiment, the humidity in the humidification space is adjusted by the moisture-permeable cover, and the first condition is met by adjusting the area of ​​the moisture-permeable membrane 203 and the volume of the humidification space, and / or the second condition is met by adjusting the area of ​​the moisture-permeable membrane 203 and the area of ​​the clamping plate, so as to ensure that the humidity in the humidification box 10 meets the requirements and improve the preservation effect of food.

[0273] Optionally, the area Sm of the moisture-permeable membrane 203 and the volume V of the moisture-retaining space satisfy the first condition: Sm = V * C; where C is the moisture-permeable area coefficient, and the value of C ranges from 1.90% to 3.00%.

[0274] The relevant experimental data regarding the area of ​​the moisture-permeable membrane 203, the volume of the moisture-retaining space, and the moisture permeability of the moisture-permeable membrane 203 are as follows:

[0275] <![CDATA[Moisture Permeable Membrane Area / cm 2 > <![CDATA[Moisture retention space volume / cm 3 > Moisture permeability / % humidity / % 245 10000 95％ 87.01％ 240 10000 95％ 84.67％ 280 14400 95％ 83.70％ 235 10000 95％ 83.23％ 250 10000 95％ 82.99％ 275 14400 95％ 82.36％ 260 10000 95％ 81.19％ 255 10000 95％ 80.67％ 270 14400 95％ 79.94％ 255 14400 95％ 79.58％ 260 14400 95％ 74.31％

[0276] The range of the moisture permeability area coefficient C is 1.90% to 3.00%, at which point the humidity inside the humidification box 10 is greater than or equal to 80%.

[0277] When the moisture permeability area coefficient is less than 1.90%, the humidity inside the humidification box 10 cannot reach 80%. This data indicates that there is a certain quantitative relationship between the area of ​​the moisture permeability membrane 203 and the volume of the humidification space. For example, when the volume of the humidification space is 10000cm3, the area of ​​the moisture permeability membrane 203 should be between 235-260cm2 to meet the humidity requirements.

[0278] Optionally, the area Sm of the moisture-permeable membrane 203 and the area Sg of the clamping plate satisfy the second condition: 0.30Sg≤Sm≤0.57Sg. This ensures that the humidity inside the humidification box 10 meets the requirements while preventing frost formation. It should be noted that the area of ​​the clamping plate here refers to the area of ​​one side only.

[0279] When the area of ​​the moisture-permeable membrane 203 and the area of ​​the clamping plate meet the second condition, it helps to improve the utilization rate of the moisture-permeable membrane 203 and reduce production costs.

[0280] The results regarding the effect of the area of ​​the moisture-permeable membrane 203 and the area of ​​the plywood on the humidity of the moisturizing space are detailed in the table below.

[0281] <![CDATA[Moisture permeable membrane area S m > 20000 23000 26000 29000 32000 35000 <![CDATA[Splint area S g > 66946 66946 66946 66946 66946 66946 <![CDATA[S m / S g ]]> 30％ 34％ 39％ 43％ 48％ 52％ humidity 85% - Cream 84％ 84％ 83％ 83％ 82％ <![CDATA[Moisture Permeable Membrane Area S m > 38000 41000 44000 47000 50000 53000 <![CDATA[The area S of the splint g > 66946 66946 66946 66946 66946 66946 <![CDATA[S m / S g ]]> 57％ 61％ 66％ 70％ 75％ 79％ humidity 81％ 80％ 79％ 75％ 70％ 69％ <![CDATA[Moisture Permeable Membrane Area S m > 56000 59000 62000 66946 <![CDATA[The splint area S g > 66946 66946 66946 66946 <![CDATA[S m / S g ]]> 84％ 88％ 93％ 100％ humidity 68％ 68％ 67％ 65％

[0282] As shown in the table above, the relationship between Sm and Sg is 0.30Sg≤Sm≤0.57Sg. At this point, the humidity inside the humidifying box 10 meets the requirements, and no frost formation is observed. When the proportion of Sm to Sg is less than 0.30, although the humidity inside the humidifying box 10 exceeds 80%, the area of ​​the permeable membrane 203 is too small. As water vapor permeates through the permeable membrane 203 to the top of the humidifying cover, it easily accumulates, leading to condensation and eventually frost formation over time. When the proportion of Sm to Sg is greater than 0.57, the humidity inside the humidifying box 10 does not reach 80%. This is mainly because the permeable area is too large, resulting in too much water vapor permeating through the permeable membrane 203 to the top of the humidifying cover.

[0283] Optionally, the clamping plate includes: a first clamping plate 201 having a plurality of first moisture-permeable holes 2011; and a second clamping plate 202 having a plurality of second moisture-permeable holes 2021 and detachably connected to the first clamping plate 201; wherein the first moisture-permeable holes 2011 and the second moisture-permeable holes 2021 are correspondingly arranged, and the moisture-permeable membrane 203 is located between the first moisture-permeable holes 2011 and the second moisture-permeable holes 2021. The clamping plate here is composed of the first clamping plate 201 and the second clamping plate 202. When calculating the area of ​​the clamping plate, only the area of ​​the first clamping plate 201 or the second clamping plate 202 needs to be calculated (i.e., a single-sided clamping plate is calculated).

[0284] Optionally, the ratio of the air volume of the quick-freezing space to the air volume of the humidifying space is in the range of 10 to 20.

[0285] The storage basket is placed at the opening of the cabinet 50. The cold air blown out of the freezer's air outlet enters the quick-freeze space through the quick-freeze air vent, and flows into the interlayer space above the moisture-permeable cover through the anti-frost air vent (first ventilation section 101). The circulating airflow inside the cabinet flows into the moisturizing space through the moisturizing air vent (third ventilation section 102).

[0286] The cold air entering the quick-freezing compartment must ensure the rapid freezing of the food. In principle, the greater the airflow into the quick-freezing compartment, the better the freezing effect. The function of the airflow above the moisture-permeable cover is as follows: Moisture in the humidification compartment permeates through the moisture-permeable membrane 203 into the interlayer space above the moisture-permeable cover. If this moisture is not removed in time, it will frost above the moisture-permeable cover due to the temperature being below the dew point, reducing the effectiveness of the moisture-permeable membrane 203. The cold air inside the humidification box 10 serves two purposes: first, it carries the moisture inside the humidification box 10 out, preventing prolonged contact between moisture and the inner wall of the humidification box 10, which can lead to condensation and frost formation; second, it provides a driving force for the moisture-permeable membrane 203, allowing moisture to continuously permeate through it through the airflow circulation, thus ensuring the stability of the humidity inside the humidification box 10.

[0287] The airflow distribution between the quick-freezing space and the space above the permeable cover is interconnected. Once the airflow in the quick-freezing space is determined, the airflow in the interlayer space above the permeable cover can be confirmed.

[0288] This embodiment presents six experimental schemes for the air volume of the quick-freezing space and the air volume of the humidifying space. The relevant experimental data and results are shown in the table below.

[0289] Option 1: The air volume of the quick-freezing space is 110L / min, the air volume of the humidifying space is 13.4L / min, the humidifying box is 10, and the moisture-permeable cover has a uniform flow line that can cover the entire area inside the box.

[0290] Option 2: The airflow in the quick-freezing space is 76.5L / min, and the airflow in the humidifying space is 9.4L / min. The flow lines in the humidifying box 10 are uneven, and the airflow cannot cover the entire area inside the box, which poses a risk of frost formation. The flow field of the moisture permeable plate is uniform.

[0291] Option 3: The airflow in the quick-freezing compartment is 42.1L / min, and the airflow in the moisturizing compartment is 18.9L / min. The airflow of the moisturizing box 10 and the moisture-permeable cover is uneven, and the airflow cannot cover the entire area, which poses a great risk of frost formation.

[0292] Option 4: The airflow in the quick-freezing space is 189.9 L / min, and the airflow in the humidifying space is 8.8 L / min. The flow lines in the humidifying box are uneven, and the airflow cannot fully cover the entire area inside the box, which poses a risk of frost formation. The permeable cover has a uniform flow field.

[0293] Option 5: The airflow in the quick-freezing space is 42.4L / min, and the airflow in the humidifying space is 11.7L / min. The flow lines in the humidifying box 10 are uneven, and the airflow cannot fully cover the entire area inside the box, posing a risk of frost formation. The flow field of the moisture-permeable cover is also uneven.

[0294] Option 6: The airflow in the quick-freezing space is 42.4L / min, and the airflow in the humidifying space is 16.6L / min. The flow lines in the humidifying box 10 are uneven, and the airflow cannot fully cover the entire area inside the box, posing a risk of frost formation. The flow field of the moisture-permeable cover is extremely uneven.

[0295]

[0296] According to the measured data, the temperature of the quick-freezing chamber is closely related to the air volume supplied to it. A larger air volume results in a lower measured temperature, better meeting the requirements of the quick-freezing chamber. Conversely, a smaller air volume in the quick-freezing chamber results in a lower measured temperature compared to a larger air volume. When the air volume of the humidifying chamber (i.e., air circulation / humidifying chamber volume) is less than 1, moisture inside the humidifying chamber cannot be expelled in time. Due to the effect of the moisture-permeable membrane, the humidity remains below 90%, but frost has already formed on the inner wall of the humidifying chamber and under the humidifying cover. When the air volume of the humidifying chamber (i.e., air circulation / humidifying chamber volume) is greater than 1, moisture inside the humidifying chamber can be effectively expelled, and the effect of the moisture-permeable membrane is also enhanced. In this case, no frost forms on the inner wall of the humidifying chamber.

[0297] Therefore, a ratio of 10 to 20 between the air volume of the quick-freezing compartment and the air volume of the humidifying compartment is preferable.

[0298] This disclosure also provides a storage basket, including: a humidifying box 10 and an expansion box 40.

[0299] The humidifying box 10 has an opening at the top and is equipped with a first ventilation section 101; the expansion box 40 has a semi-open structure and is equipped with a fourth ventilation section 401; wherein, when the expansion box 40 is partially enclosed outside the humidifying box 10, the first ventilation section 101 and the fourth ventilation section 401 are correspondingly arranged and connected, and the ventilation areas of the first ventilation section 101 and the fourth ventilation section 401 partially or completely overlap.

[0300] Using the storage basket provided in this embodiment, the expansion box 40 can move laterally relative to the moisturizing box 10. When the expansion box 40 is partially enclosed outside the moisturizing box 10, the ventilation areas of the first ventilation section 101 and the fourth ventilation section 401 partially or completely overlap, making the airflow flow rate through the first ventilation section 101 variable. This allows the moisturizing box 10 to form different storage conditions, thereby increasing the diversity of storage in the storage basket, especially the moisturizing box 10, meeting different user needs, and improving the user experience.

[0301] For example, the first storage condition is when the expansion box 40 partially encloses the outside of the humidifying box 10, and the ventilation areas of the first ventilation section 101 and the fourth ventilation section 401 completely overlap. The second storage condition is when the expansion box 40 partially encloses the outside of the humidifying box 10, and the ventilation areas of the first ventilation section 101 and the fourth ventilation section 401 partially overlap, resulting in reduced airflow in the first ventilation section 101. The third storage condition is when the expansion box 40 is pulled laterally relative to the humidifying box 10, and the ventilation areas of the first ventilation section 101 and the fourth ventilation section 401 completely overlap. In this case, the airflow into the humidifying box 10 is at its maximum. The fourth storage condition is when the expansion box 40 is pulled laterally relative to the humidifying box 10, and the ventilation areas of the first ventilation section 101 and the fourth ventilation section 401 partially overlap. Under the fourth storage condition, the airflow into the humidifying box 10 is greater than that under the second storage condition.

[0302] Optionally, the first ventilation section 101 is arranged around the circumferential sidewall of the humidification box 10, and the fourth ventilation section 401 is arranged around the circumferential sidewall of the expansion box 40. This helps to ensure the consistency between the fourth ventilation section 401 and the first ventilation section 101, thereby ensuring the air intake of the humidification box 10.

[0303] Optionally, when the ventilation area of ​​the fourth ventilation section 401 partially overlaps with the ventilation area of ​​the first ventilation section 101, the ventilation area of ​​the fourth ventilation hole 4011 of the fourth ventilation section 401 may be smaller than the ventilation area of ​​the first ventilation hole 1011 of the first ventilation section 101. Alternatively, the number of fourth ventilation holes 4011 in the fourth ventilation section 401 may be less than the number of first ventilation holes 1011 in the first ventilation section 101.

[0304] This disclosure also provides a storage basket, including a humidifying box 10 and an expansion box 40.

[0305] The humidifying box 10 has a third ventilation section 102; the extension box 40 can be fitted onto the outside of the humidifying box 10 and has a fifth ventilation section 402 on its side wall; wherein the ventilation area of ​​the third ventilation section 102 and the ventilation area of ​​the fifth ventilation section 402 are partially or completely corresponding.

[0306] The storage basket provided in this embodiment achieves the purpose of moisture control and preservation of food through the humidification box 10 and the third ventilation section. Furthermore, the expansion box 40 not only expands the storage space but also connects the ventilation areas of the fifth ventilation section 402 and the third ventilation section 102, thereby further realizing the humidity regulation function within the humidification box 10 and meeting diverse storage needs. When food is stored in the humidification box, external airflow flows into the humidification box through the third ventilation section, which not only removes excess moisture from the humidification box but also reduces or prevents frost formation inside, ensuring that the humidity within the humidification box remains within a certain range, thus achieving the purpose of moisture control and preservation of food.

[0307] Optionally, when the humidification box 10 and the expansion box 40 are stacked in the same direction, the ventilation area of ​​the third ventilation section 102 corresponds to the ventilation area of ​​the fifth ventilation section 402. That is, it can be understood that the ventilation area of ​​the third ventilation section 102 is the same as the ventilation area of ​​the fifth ventilation section 402 and they are completely connected.

[0308] Optionally, when the humidifying box 10 and the expansion box 40 are stacked in opposite directions, the ventilation area of ​​the third ventilation section 102 corresponds to the ventilation area of ​​the fifth ventilation section 402. That is, the ventilation area of ​​the third ventilation section 102 is connected to the ventilation area of ​​the fifth ventilation section 402, the third ventilation section 102 is blocked by the side wall of the expansion box 40, and the actual ventilation area of ​​the third ventilation section 102 is smaller than its total ventilation area.

[0309] Cool air inside the cabinet 50 flows into the humidification box 10 through the third ventilation section 102, preventing high-humidity air from freezing and frostling on the walls of the humidification box 10. The ventilation area of ​​the third ventilation section 102 affects the humidity inside the humidification box 10; different ventilation areas result in different humidity levels inside the humidification box 10.

[0310] When the expansion box 40 is in use, the humidifying box 10 is separate from the expansion box 40, and the third ventilation section 102 of the humidifying box 10 is fully ventilated, resulting in a large ventilation area and low humidity inside the humidifying box 10. When the expansion box 40 is not in use, and is stacked with the humidifying box 10 in opposite directions, the area of ​​the third ventilation section 102 is different, leading to different humidity levels inside the humidifying box 10. This allows for the storage of at least two types of food with different humidity levels. Therefore, the storage basket provided in this embodiment can maintain at least three different humidity levels, thereby storing three different types of food to meet the different needs of users.

[0311] Optionally, the opening edge of the cabinet 50 is constructed with a stepped structure 502, and the first overlapping part 104 of the humidifying box 10 and the third overlapping part 404 of the extension box 40 form a hanging ear structure to be overlapped and fixed to the stepped structure 502.
