Description

Technical Field

[0001] This invention relates to the field of refrigerator technology, and in particular to a drawer assembly and a refrigerator. Background Art

[0002] To enhance the preservation of fruits and vegetables, refrigerators typically include active humidification devices in addition to moisture-retaining structures. These devices spray water mist onto the fruits and vegetables, forming a water film on their surface and slowing down transpiration. However, existing humidification solutions are generally single-point and unidirectional, resulting in uneven humidification and a tendency for condensation. Some multi-point humidification solutions are structurally complex, making assembly and maintenance difficult. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a drawer assembly with a simple structure that enables uniform diffusion of water mist and provides good atomization humidification effect.

[0004] The present invention also provides a refrigerator having the above-described drawer assembly.

[0005] According to a first aspect of the present invention, a drawer assembly includes: a drawer body having a receiving cavity; a cover having an opening in the receiving cavity; and an atomizing module including an atomizing component and a mist guide tube. The atomizing component has a spray nozzle for providing water mist to the receiving cavity. The mist guide tube is disposed in the receiving cavity and located on one side of the atomizing component. One end of the mist guide tube facing the atomizing component has a mist guide opening corresponding to the position of the spray nozzle. The mist guide opening and the spray nozzle are arranged at intervals. The mist guide tube also has a plurality of mist outlet holes communicating with the receiving cavity.

[0006] According to the first aspect of the present invention, the drawer assembly has at least the following beneficial effects: by aligning the mist guide port of the mist guide tube with the spray port of the atomizing component and arranging them at intervals, the atomizing component delivers water mist into the mist guide tube. During the process of the water mist entering the mist guide tube from the spray port through the mist guide port, a local negative pressure is formed in the space between the mist guide port and the spray port, causing the surrounding air to be drawn into the water mist. The airflow makes the water mist diffuse a greater distance and a wider range in the mist guide tube, thereby making the water mist evenly output into the receiving cavity through multiple mist outlets, achieving uniform diffusion of water mist into the receiving cavity, which is beneficial to improving the atomization humidification effect, eliminating the need for a fan, and simplifying the structure.

[0007] According to an embodiment of the first aspect of the present invention, the minimum distance between the mist guide orifice and the spray orifice is a, which satisfies 5mm≤a≤50mm.

[0008] According to an embodiment of the first aspect of the present invention, a plurality of mist outlets are arranged at intervals along the length direction of the mist guide tube, the distance between two adjacent mist outlets is b, which satisfies 5mm≤b≤50mm; and / or, the inner diameter of the mist outlet is d, which satisfies 1mm≤d≤10mm.

[0009] According to an embodiment of the first aspect of the present invention, the drawer body includes a panel located at the front end, the panel being transparent, and the mist guide tube being located at one end of the receiving cavity near the panel.

[0010] According to an embodiment of the first aspect of the present invention, the atomizing module further includes a lamp source, the lamp source being disposed within the receiving cavity and illuminating at least the mist outlet side of the mist outlet.

[0011] According to an embodiment of the first aspect of the present invention, the drawer assembly further includes an inner drawer disposed within the receiving cavity, the inner drawer being slidably mounted on the cover in a front-rear direction, and the mist guide tube being located at the bottom of the inner drawer and embedded in the inner drawer.

[0012] According to an embodiment of the first aspect of the present invention, the mist guide tube is detachably connected to the inner drawer, or the mist guide tube is formed in the inner drawer and is an integral structural component of the inner drawer.

[0013] According to an embodiment of the first aspect of the present invention, the inner drawer includes a handle located at the front end, the handle having a downward-facing groove, and the mist guide tube being located within the groove.

[0014] According to an embodiment of the first aspect of the present invention, the atomizing component is disposed within the receiving cavity; and / or, the atomizing component is arranged at a distance from the mist guide tube.

[0015] According to an embodiment of the first aspect of the present invention, the atomizing assembly includes a liquid storage box and an atomizing element, the atomizing element being disposed on one side of the liquid storage box, the liquid storage box having a liquid outlet corresponding to the position of the atomizing element, and the atomizing element having the spray nozzle.

[0016] According to an embodiment of the first aspect of the present invention, the cover is in a sealing fit with the drawer body.

[0017] A refrigerator according to a second aspect of the present invention includes a cabinet, a door connected to the cabinet, and a drawer assembly according to a first aspect of the present invention, the drawer assembly being disposed within the cabinet.

[0018] According to a second aspect embodiment of the present invention, the refrigerator has at least the following beneficial effects: Because the refrigerator uses the aforementioned drawer assembly, by aligning the mist guide port of the mist guide tube with the spray port of the atomizing component and arranging them at intervals, the atomizing component delivers water mist into the mist guide tube. During the process of the water mist entering the mist guide tube from the spray port through the mist guide port, a local negative pressure is formed in the space between the mist guide port and the spray port, causing the surrounding air to be drawn into the water mist. The airflow makes the water mist diffuse a greater distance and a wider range within the mist guide tube, thereby allowing the water mist to be evenly output into the receiving cavity through multiple mist outlets, achieving uniform diffusion of the water mist into the receiving cavity, which is beneficial for improving the atomization humidification effect. It eliminates the need for a fan and has a simple structure.

[0019] According to an embodiment of a second aspect of the present invention, the cabinet has a refrigerated compartment and includes a shelf disposed in the refrigerated compartment, the drawer assembly is disposed in the refrigerated compartment and located below the shelf, and the cover is detachably mounted on the shelf.

[0038] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0039] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0040] In the description of the present invention, "several" means one or more, "many" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0041] In the description of this invention, unless otherwise explicitly defined, terms such as setting, installing, connecting, assembling, and cooperating should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0042] Currently, to improve the preservation of fruits and vegetables, refrigerators typically include active humidification devices in addition to internal moisture-retaining structures. These devices spray water mist onto the fruits and vegetables, forming a water film on their surface and slowing down transpiration. However, existing humidification solutions are generally single-point and unidirectional, resulting in uneven humidification and a tendency for condensation. Some multi-point humidification solutions are structurally complex, making assembly and maintenance difficult.

[0043] To solve the above problems, refer to Figure 1 A first aspect of the present invention provides a drawer assembly installed inside a refrigerator. (See also...) Figure 12 It is understood that the refrigerator includes a cabinet 100, which has a refrigerator compartment 101 and a freezer compartment 104, and drawer assemblies are located in the refrigerator compartment 101. Shelves 102 are provided in the refrigerator compartment 101, and drawer assemblies are located in the refrigerator compartment 101 and below the shelves 102.

[0044] It is understood that the drawer assembly includes a drawer body 110, a lid 103, and a misting module 130. The drawer body 110 is slidably connected to the refrigerator body 100 in the front-to-back direction, and the width direction of the drawer body 110 is parallel to the left-to-right direction of the refrigerator. The drawer body 110 has a cavity 111 for storing fruits, vegetables, and other items. The lid 103 is detachably installed inside the refrigerator body 100 and covers the opening of the cavity 111 to seal it, which helps to ensure the moisture retention effect inside the cavity 111, thereby effectively improving the preservation effect of fruits and vegetables placed in the cavity 111.

[0045] Of course, in other embodiments, in applications where the requirement for moisturizing effect is not high, there may also be a gap between the cover 103 and the drawer body 110.

[0046] Specifically, refer to Figure 4 , Figure 7 and Figure 9The cover 103 is detachably mounted on the shelf 102. The shelf 102 has multiple mounting seats 105 located on the outer periphery of the cover 103. The cover 103 has connecting ears 116 that insert into the inner cavity 121 of the mounting seats 105, extending from the outer peripheral wall of the cover 103 towards the mounting seats 105. Furthermore, the mounting seats 105 have insertion ports 106 communicating with the inner cavity 121, located at the end of the mounting seats 105 near the shelf 102. Thus, during installation, the connecting ears 116 of the cover 103 enter the inner cavity 121 through the insertion ports 106. Under the influence of gravity, the cover 103 falls, causing the connecting ears 116 to press against the bottom wall of the inner cavity 121, thereby securing the cover 103 to the shelf 102. At this time, the connecting ear 116 and the socket 106 are staggered in the vertical direction, which can prevent the connecting ear 116 from coming out of the mounting base 105 and improve the stability of the installation.

[0047] It is understood that the atomizing module 130 includes an atomizing component and a mist guide tube 133, wherein the atomizing component is used to generate water mist and supply water mist to the receiving cavity 111. Specifically, the atomizing component is located within the receiving cavity 111 and includes a liquid storage box 131 and an atomizing element 132. The liquid storage box 131 is mounted on the cover 103, and the atomizing element 132 is mounted on the left side of the liquid storage box 131. The mist guide tube 133 is located within the receiving cavity 111 and is disposed on the left side of the liquid storage box 131, and the length direction of the mist guide tube 133 is parallel to the width direction of the drawer body 110. It is understood that the atomizing component and the mist guide tube 133 are both disposed within the receiving cavity 111, which can prevent water leakage to other areas of the cabinet 100 other than the receiving cavity 111.

[0048] Of course, in some other embodiments, the mist guide tube 133 is disposed inside the receiving cavity 111, and the atomizing component can be disposed outside the receiving cavity 111. For example, the liquid storage box 131 of the atomizing component is installed on the outer side wall of the drawer body 110, and the liquid storage box 131 and the drawer body 110 are sealed at the spray nozzle.

[0049] Reference Figure 6 and Figure 8It is understood that the liquid storage box 131 is provided with a liquid outlet 134 corresponding to the position of the atomizing element 132. The liquid outlet 134 is used to allow the water in the liquid storage box 131 to contact the atomizing element 132. The atomizing element 132 is provided with a spray nozzle. At the same time, the end of the mist guide tube 133 facing the atomizing element 132 is provided with a mist guide port 136 corresponding to the position of the spray nozzle. The mist guide tube 133 is also provided with multiple mist outlets 135 communicating with the receiving cavity 111. The multiple mist outlets 135 are arranged at intervals along the length direction of the mist guide tube 133. It is understood that the atomizing element 132 adopts an ultrasonic atomizing plate. The atomizing element 132 is provided with multiple fine spray nozzles. When the atomizing element 132 is energized, the atomizing element 132 generates high-frequency vibration, thereby dispersing the water in the liquid storage box 131 into water mist. The water mist can pass through the spray nozzle and be transported into the mist guide tube 133 through the mist guide port 136.

[0050] Understandably, the mist guide 136 and the spray nozzle are arranged alternately. Specifically, the mist guide tube 133 is located on the left side of the liquid storage box 131 and is arranged alternately with the liquid storage box 131 and the atomizing element 132. During the process of water mist entering the mist guide tube 133 from the spray nozzle through the mist guide 136, a local negative pressure is formed between the mist guide 136 and the spray nozzle, causing the surrounding air to be drawn into the water mist. This airflow allows the water mist to diffuse a greater distance and a wider range within the mist guide tube 133, resulting in the water mist being evenly output into the receiving cavity 111 through multiple mist outlets 135. This achieves uniform diffusion of the water mist into the receiving cavity 111, which is beneficial for improving the atomization and humidification effect. No fan is required, and the structure is simple. Furthermore, increasing the diffusion range of the water mist through airflow eliminates the need for a fan, simplifying the structure and saving costs.

[0051] Meanwhile, since the mist guide tube 133 is located on the left side of the liquid storage box 131 and is arranged at intervals with the liquid storage box 131 and the atomizing element 132, the mist guide tube 133 is not connected to the liquid storage box 131 or to the atomizing element 132. The structure is simple, and the liquid storage box 131 can be disassembled and installed independently, which is convenient for installation and later maintenance.

[0052] Of course, in other embodiments, the mist guide tube 133 and the liquid storage box 131 can be in contact or connected, as long as the mist guide port 136 of the mist guide tube 133 is positioned to correspond to the spray port and arranged at intervals.

[0053] It is understood that the drawer body 110 includes a front panel 112, which is transparent and made of materials such as plastic or glass, allowing users to easily observe the arrangement of items inside the drawer. It is understood that the transparent panel can be 100% transparent or have a transparency of 30%, 50%, 80%, etc., as long as the transparency of the panel 112 is sufficient for the user to observe the interior of the receiving cavity 111. It is understood that the mist guide tube 133 is located at the end of the receiving cavity 111 near the panel 112. When the atomizing module 130 is working, the user can easily observe the water mist sprayed from the mist outlet 135 through the panel 112, thus providing a clear view of the atomization effect. It is understood that the liquid storage box 131 is also located at the end of the receiving cavity 111 near the panel 112, allowing the user to easily install and remove the liquid storage box 131 for convenient water addition or cleaning.

[0054] Reference Figure 2 and Figure 4 It is understandable that the liquid storage box 131 is provided with a top cover 138. The liquid storage box 131 can be slidably installed on the cover body 103 in the front-back direction. When the liquid storage box 131 is pulled out from the cover body 103, the top cover 138 can be opened to add water or clean it, which helps to improve the convenience of daily maintenance.

[0055] Understandably, the liquid storage box 131 has first flanges 117 on both sides along the width direction of the drawer body 110, and the first flanges 117 extend outward from the outer peripheral wall of the liquid storage box 131. At the same time, the cover 103 has two first sliding grooves 118, and the two first sliding grooves 118 are arranged on both sides of the liquid storage box 131 along the width direction of the drawer body 110. The first flanges 117 are inserted into the first sliding grooves 118, and the bottom wall of the first flanges 117 presses against the inner bottom wall of the first sliding grooves 118. The first flanges 117 can slide within the first sliding grooves 118, so that the liquid storage box 131 is slidably connected to the cover 103.

[0056] Understandably, the drawer assembly also includes an inner drawer 113, which is located in the receiving cavity 111 and to the left of the liquid storage box 131. The inner drawer 113 is slidably mounted on the cover 103 in the front-to-back direction. Specifically, the inner drawer 113 has second flanges 119 on both sides along the width direction of the drawer body 110, and the second flanges 119 extend outward from the outer peripheral wall of the inner drawer 113. At the same time, the cover 103 has two second sliding grooves 120, and the two second sliding grooves 120 are arranged on both sides of the inner drawer 113 along the width direction of the drawer body 110. The second flanges 119 are inserted into the second sliding grooves 120, and the bottom wall of the second flanges 119 presses against the inner bottom wall of the second sliding grooves 120. The second flanges 119 can slide within the second sliding grooves 120, thereby realizing the slidable connection of the inner drawer 113 to the cover 103.

[0057] Understandably, the thickness of the inner drawer 113 is equal to the thickness of the liquid storage box 131 in the vertical direction. This allows the outer bottom wall of the inner drawer 113 and the liquid storage box 131 to occupy the same height space in the receiving cavity 111, thus making the space inside the receiving cavity 111 more regular and convenient for users to place fruits and vegetables. At the same time, the inner drawer 113 and the liquid storage box 131 are set separately, and both can move in the front and back direction, thereby achieving independent assembly and disassembly of the two without interference. This simplifies the structure and facilitates daily maintenance.

[0058] Reference Figure 3 It is understandable that, since the mist guide tube 133 is located in the receiving cavity 111 and installed at the front end of the cover 103 near the panel 112, the mist guide tube 133 will occupy a certain height space of the receiving cavity 111. When the drawer body 110 is opened and closed, it will move relative to the mist guide tube 133. If the fruits and vegetables in the receiving cavity 111 occupy the space behind the mist guide tube 133, the fruits and vegetables will interfere with the mist guide tube 133 during the opening and closing of the drawer body 110. Therefore, the space behind the mist guide tube 133 in the receiving cavity 111 is often not utilized, and the space utilization rate of the receiving cavity 111 is insufficient.

[0059] Therefore, the mist guide tube 133 is installed in the inner drawer 113 and is located at the bottom of the inner drawer 113 and embedded in the inner drawer 113, so that the mist guide tube 133 will not protrude from the bottom of the inner drawer 113 into the receiving cavity 111. This helps to avoid interference between the fruits and vegetables in the receiving cavity 111 and the mist guide tube 133, while making full use of the space at the rear end of the mist guide tube 133, thereby improving the space utilization rate of the receiving cavity 111.

[0060] Reference Figure 10 and Figure 11 It is understood that the inner drawer 113 includes a handle 114 located at the front end. The handle 114 is used to pull the inner drawer 113 to open and close. The handle 114 has a groove 115 with the opening facing downward. The mist guide tube 133 is located in the groove 115. On the one hand, this facilitates the embedded installation of the mist guide tube 133, which can save space in the receiving cavity 111. On the other hand, since the handle 114 is located at the front end of the inner drawer 113, the installation of the mist guide tube 133 in the groove 115 can ensure that the mist guide tube 133 is located at the front end of the receiving cavity 111 near the panel 112, which makes it easy for the user to observe the water mist sprayed by the mist guide tube 133 and realize a direct display of the humidification process.

[0061] It is understandable that the mist guide tube 133 is detachably connected to the inner drawer 113. For example, the mist guide tube 133 can be detachably installed in the groove 115 by means of a snap-fit; or the mist guide tube 133 can be installed and fixed by means of bolt connection, adhesive connection, etc., which is convenient for daily maintenance.

[0062] In other embodiments, the mist guide tube 133 is formed on the inner drawer 113 and forms an integral structural component with the inner drawer 113. The mist guide tube 133 and the inner drawer 113 can be integrally injection molded, which helps to simplify the structure, reduce installation steps, and thus improve production efficiency.

[0063] Reference Figure 3 and Figure 11 The atomizing module 130 also includes a light source 137, which can be an LED lamp. The light source 137 is located within the receiving cavity 111 and illuminates at least the mist outlet side of the mist outlet 135. It is understood that the mist outlet 135 is located on the bottom wall of the mist guide tube 133, and the axis of the mist outlet 135 extends vertically. Therefore, water mist is sprayed out from the bottom of the mist guide tube 133. The mist outlet side of the mist outlet 135 is the space within the receiving cavity 111 located below the mist guide tube 133. The light from the light source 137 illuminates the mist outlet side. Simultaneously, with the aid of a fully transparent or semi-transparent panel 112, the light source 137 illuminates the water mist output from the mist outlet 135, thereby showcasing the atomization and humidification process and enhancing the user experience.

[0064] It is understood that the light source 137 is installed on either side of the mist guide pipe 133 in the front-to-back direction. In this embodiment, the light source 137 is installed on the rear side of the mist guide pipe 133. Furthermore, the rear side of the mist guide pipe 133 has a rearwardly extending mounting portion 140, and the light source 137 is installed on the mounting portion 140.

[0065] In other embodiments, the light source 137 is embedded in the groove 115 so that the light source 137 does not protrude from the receiving cavity 111, which helps to avoid interference between the light source 137 and the fruits and vegetables in the receiving cavity 111.

[0066] Understandably, when the user opens the door, or in demonstration mode, the atomizing element 132 activates, and the light source 137 turns on, illuminating the mist-emitting side, making it easy for the user to observe the water mist discharged from the mist guide tube 133, providing a good display effect. During normal refrigerator operation at the user's end, when the user closes the door, the atomizing element 132 activates periodically, and the light source 137 turns off, which helps to achieve energy savings while ensuring humidification. Specifically, the atomizing element 132 can activate periodically based on the humidity value detected by the humidity sensor located in the receiving cavity 111. For example, the atomizing element 132 activates when the humidity sensor detects a low humidity value and stops working when the humidity value is high. Alternatively, the atomizing element 132 can be activated periodically through a timed activation mechanism.

[0067] Reference Figure 3 and Figure 5The mist guide tube 133 has multiple spaced mist outlet holes 135 along its length, and the distance between two adjacent mist outlet holes 135 is b, which satisfies 5mm≤b≤50mm. It can be understood that the distance b between two adjacent mist outlet holes 135 is the center distance between two adjacent mist outlet holes 135.

[0068] Understandably, with multiple mist outlets 135 evenly arranged in the mist guide tube 133, and given a fixed length of the mist guide tube 133, when b is less than 5mm, the distance between two adjacent mist outlets 135 is too small, resulting in a large number of mist outlets 135. The arrangement of the mist outlets 135 in the mist guide tube 133 is too dense, causing most of the water mist to be discharged from the mist outlets 135 closer to the atomizing element 132, with only a small portion being discharged from the mist outlets 135 farther from the atomizing element 132. This leads to uneven mist output from the mist guide tube 133, resulting in inconsistent humidification of fruits and vegetables in different locations, thus affecting the humidification effect. When b is greater than 50mm, the distance between two adjacent mist outlets 135 is too large, resulting in an insufficient number of mist outlets 135 and an overly sparse arrangement of mist outlets 135 in the mist guide tube 133. This causes some water mist to accumulate in the mist guide tube 133 instead of being discharged in time, resulting in poor atomization and affecting the humidification effect. It may even cause water to accumulate in the mist guide tube 133 and be discharged through the mist outlets 135, leading to water accumulation in the inner drawer 113. Therefore, when the distance b between two adjacent mist outlets 135 satisfies 5mm≤b≤50mm, it can ensure uniform mist output from the mist guide tube 133 and achieve a good atomization effect, thereby ensuring a good humidification effect and avoiding dripping and water accumulation.

[0069] It is understood that in this embodiment, the mist outlet 135 can be configured as a circle, rectangle, or polygon. Simultaneously, the inner diameter of the mist outlet 135 is d, satisfying 1mm ≤ d ≤ 10mm. It is also understood that the inner diameter d of the mist outlet 135 is the minimum inner diameter of the mist outlet 135, which is twice the minimum distance from the inner circumferential wall of the mist outlet 135 to its axis.

[0070] Understandably, when the inner diameter d of the mist outlet 135 is less than 1mm, the size of the mist outlet 135 is too small. This will cause some water mist to not be discharged through the mist outlet 135 in time and instead accumulate into water droplets in the mist guide tube 133, resulting in poor atomization and affecting the humidification effect. It may even cause water to accumulate in the mist guide tube 133 and drip down through the mist outlet 135, leading to water accumulation in the inner drawer 113. When the inner diameter d of the mist outlet 135 is greater than 10mm, the size of the mist outlet 135 is too large. This causes most of the water mist to be discharged from the mist outlet 135 closer to the atomizing element 132, with only a small portion discharged from the mist outlet 135 farther from the atomizing element 132. This results in uneven mist output from the mist guide tube 133, leading to inconsistent humidification of fruits and vegetables in different locations and affecting the humidification effect. Therefore, when the inner diameter d of the mist outlet 135 satisfies 1mm≤d≤10mm, it can ensure that the mist guide tube 133 can produce mist evenly and achieve a good atomization effect, thereby ensuring a good humidification effect and avoiding dripping and water accumulation.

[0071] It is understood that in this embodiment, the distance b between two adjacent mist outlets 135 satisfies 5mm≤b≤50mm, and the inner diameter d of the mist outlet 135 satisfies 1mm≤d≤10mm.

[0072] Understandably, when b < 5mm and d < 1mm, on the one hand, the distance between two adjacent mist outlets 135 is too small, resulting in a large number of mist outlets 135. The arrangement of the mist outlets 135 in the mist guide tube 133 is too dense, causing most of the water mist to be discharged from the mist outlets 135 closer to the atomizing element 132, with only a small portion discharged from the mist outlets 135 farther from the atomizing element 132. This leads to uneven mist output from the mist guide tube 133, resulting in inconsistent humidification of fruits and vegetables in different locations and affecting the humidification effect. On the other hand, if the size of the mist outlets 135 is too small, some water mist cannot be discharged through the mist outlets 135 in time and will accumulate into water droplets in the mist guide tube 133, resulting in poor atomization and affecting the humidification effect. It may even cause water to accumulate in the mist guide tube 133 and drip down through the mist outlets 135, leading to water accumulation in the inner drawer 113. In summary, when both the aperture and the aperture spacing are too small, it is easy to result in poor atomization, uneven mist distribution, and poor humidification.

[0073] When b > 50 mm and d > 10 mm, on the one hand, the distance between two adjacent mist outlets 135 is too large, resulting in an insufficient number of mist outlets 135. The arrangement of the mist outlets 135 in the mist guide tube 133 is too sparse, causing some water mist to not be discharged through the mist outlets 135 in time and instead accumulate into water droplets in the mist guide tube 133, resulting in poor atomization and affecting the humidification effect. It may even cause water to accumulate in the mist guide tube 133 and be discharged through the mist outlets 135, leading to water accumulation in the inner drawer 113. On the other hand, the size of the mist outlets 135 is too large, causing most of the water mist to be discharged from the mist outlets 135 closer to the atomizing element 132, with only a small portion discharged from the mist outlets 135 farther from the atomizing element 132. This results in uneven mist output from the mist guide tube 133, leading to inconsistent humidification of fruits and vegetables in different positions and affecting the humidification effect. In summary, when both the aperture and the aperture spacing are too large, most of the water mist is likely to be discharged from the mist outlet 135 near the atomizing element 132, meaning that only a small portion of the mist outlet 135 can discharge water mist, resulting in uneven mist output and poor humidification effect.

[0074] When b < 5 mm and d > 10 mm, that is, the distance between two adjacent mist outlets 135 is less than the radius of the mist outlet 135, the multiple mist outlets 135 arranged along the axial direction of the mist guide tube 133 will overlap sequentially, forming a through groove extending along the axial direction of the mist guide tube 133. The through groove connects the mist guide tube 133 and the receiving cavity 111, which will cause water mist to be mainly discharged from the end of the through groove near the atomizing element 132, resulting in uneven mist output from the mist guide tube 133 and poor humidification effect.

[0075] When b > 50 mm and d < 1 mm, that is, the distance between two adjacent mist outlets 135 is too large and the inner diameter of the mist outlet 135 is too small, the total area of ​​the mist outlets 135 on the mist guide tube 133 is too small, which causes some water mist to be unable to be discharged in time and to accumulate into water droplets in the mist guide tube 133, resulting in poor atomization effect, affecting the humidification effect, and may even cause water to accumulate in the mist guide tube 133 and be discharged through the mist outlet 135, thus causing water to accumulate in the inner drawer 113.

[0076] Therefore, when the distance b between two adjacent mist outlets 135 satisfies 5mm≤b≤50mm, and the inner diameter d of the mist outlet 135 satisfies 1mm≤d≤10mm, it can ensure that the mist guide tube 133 produces mist evenly and achieves a good atomization effect, thereby ensuring a good humidification effect and avoiding dripping and water accumulation.

[0077] Reference Figure 6 The minimum distance between the mist guide tube 133 and the atomizing element 132 is 'a', which satisfies 5mm ≤ a ≤ 50mm. It can be understood that the minimum distance 'a' between the mist guide tube 133 and the atomizing element 132 is the shortest distance between the end wall of the mist guide tube 133 and the atomizing element 132 along the axial direction of the mist guide tube 133.

[0078] Understandably, when a < 5 mm, the distance between the mist guide tube 133 and the atomizing element 132 is too small, making it impossible to entrain enough air. This results in the water mist failing to diffuse sufficiently within the mist guide tube 133, leading to poor atomization and affecting the humidification effect. When a > 50 mm, the distance between the mist guide tube 133 and the atomizing element 132 is too large, causing some water mist to drift directly into the receiving cavity 111 instead of entering the mist guide tube 133. This results in the water mist mainly concentrating at the end of the mist guide tube 133 closest to the atomizing element 132, leading to uneven spraying and poor humidification. Therefore, when the minimum distance a between the mist guide tube 133 and the atomizing element 132 satisfies 5 mm ≤ a ≤ 50 mm, sufficient air is entrained in the water mist, allowing it to diffuse fully within the mist guide tube 133 and exit through the mist outlet 135 into the receiving cavity 111, achieving a uniform atomization and humidification effect.

The refrigerator also includes a cabinet 100, within which the drawer assembly is disposed. It is understood that the cabinet 100 has a refrigerator compartment 101 and a freezer compartment 104.
