DETAILED DESCRIPTION

[0023] Embodiments of the present invention are described in detail below, examples of which 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 only used to explain the present invention, and cannot be understood as limiting the present invention.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0026] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, assembling, and matching should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0027] At present, in order to improve the preservation effect of fruits and vegetables, in addition to setting up a moisturizing structure in the refrigerator, refrigerators are usually equipped with active humidification devices, that is, spraying water mist on the fruits and vegetables to form a layer of water film on the surface of the fruits and vegetables to slow down the transpiration of the fruits and vegetables themselves. However, in the related technology, the existing humidification schemes are generally single-point, one-way humidification, which has the problem of uneven humidification and is prone to condensation. Some multi-point humidification schemes have complex structures and are not conducive to assembly and maintenance.

[0028] To solve the above problems, refer to Figure 1 A first aspect of the present invention provides a drawer assembly, which is installed in a refrigerator. Fig.12 It can be understood that the refrigerator includes a box body 100, the box body 100 is provided with a refrigerating compartment 101 and a freezing compartment 104, and the drawer assembly is arranged in the refrigerating compartment 101. A shelf 102 is arranged in the refrigerating compartment 101, and the drawer assembly is arranged in the refrigerating compartment 101 and is located below the shelf 102.

[0029] It can be understood that the drawer assembly includes a drawer body 110, a cover 103 and an atomization module 130, wherein the drawer body 110 is slidably connected to the box body 100 along the front-to-back direction, and the width direction of the drawer body 110 is parallel to the left-right direction of the refrigerator. The drawer body 110 is provided with a receiving cavity 111 for storing fruits and vegetables and other items, and the cover 103 is detachably installed in the box body 100, and the cover 103 is covered at the opening of the receiving cavity 111 and is used to seal the receiving cavity 111, which is conducive to ensuring the moisturizing effect in the receiving cavity 111, thereby effectively improving the preservation effect of the fruits and vegetables placed in the receiving cavity 111.

[0030] Of course, in other embodiments, in application environments where the requirement for moisturizing effect is not high, there may also be a gap between the cover 103 and the drawer body 110 .

[0031] Specifically, refer to Figure 4 , Figure 7 and Fig. 9The cover 103 is detachably mounted on the shelf 102. The shelf 102 is provided with a plurality of mounting seats 105 located on the outer periphery of the cover 103. The cover 103 is provided with connecting ears 116 plugged into the inner cavity 121 of the mounting seats 105. The connecting ears 116 extend from the outer peripheral wall of the cover 103 to the mounting seats 105. Furthermore, the mounting seats 105 are provided with a socket 106 connected to the inner cavity 121. The socket 106 is located at one end of the mounting seats 105 close to the shelf 102. Therefore, during installation, the connecting ears 116 of the cover 103 enter the inner cavity 121 from the socket 106. Under the action of gravity, the cover 103 falls, so that the connecting ears 116 press against the bottom wall of the inner cavity 121, thereby realizing the installation and fixation of the cover 103 on the shelf 102. At this time, the connecting ear 116 and the socket 106 are staggered in the up-down direction, which can prevent the connecting ear 116 from falling off the mounting seat 105, and is beneficial to improving the stability of the installation.

[0032] It is understandable that the atomization module 130 includes an atomization component and a mist guide pipe 133, wherein the atomization component is used to generate water mist and provide water mist to the accommodating chamber 111. Specifically, the atomization component is located in the accommodating chamber 111 and includes a liquid storage box 131 and an atomization element 132, the liquid storage box 131 is installed on the cover 103, and the atomization element 132 is installed on the left side of the liquid storage box 131. The mist guide pipe 133 is located in the accommodating chamber 111 and is arranged on the left side of the liquid storage box 131, and the length direction of the mist guide pipe 133 is parallel to the width direction of the drawer body 110. It is understandable that the atomization component and the mist guide pipe 133 are both arranged in the accommodating chamber 111, which can prevent water from leaking to other areas in the box 100 except the accommodating chamber 111.

[0033] Of course, in other embodiments, the mist guide pipe 133 is disposed in the accommodating cavity 111, and the atomization component can be disposed outside the accommodating cavity 111. For example, the liquid storage box 131 of the atomization component is installed on the outer wall of the drawer body 110, and the liquid storage box 131 and the drawer body 110 can be sealed at the spray port.

[0034] Reference Figure 6 and Figure 8It can be understood that the liquid storage box 131 is provided with a liquid outlet 134 corresponding to the position of the atomizing element 132, and the liquid outlet 134 is used to make the water in the liquid storage box 131 contact the atomizing element 132. The atomizing element 132 is provided with a spray port, and at the same time, the end of the mist guide pipe 133 facing the atomizing element 132 is provided with a mist guide port 136 corresponding to the position of the spray port. The mist guide pipe 133 is also provided with a plurality of mist outlet holes 135 connected to the accommodating cavity 111, and the plurality of mist outlet holes 135 are arranged at intervals along the length direction of the mist guide pipe 133. It can be understood that the atomizing element 132 adopts an ultrasonic atomizing sheet, and the atomizing element 132 is provided with a plurality of fine spray ports. When the atomizing element 132 is energized, the atomizing element 132 generates high-frequency vibrations, thereby breaking up the water in the liquid storage box 131 into water mist, and the water mist can pass through the spray port and be transported to the mist guide pipe 133 through the mist guide port 136.

[0035] It is understandable that the mist guide port 136 is arranged at intervals from the spray port. Specifically, the mist guide pipe 133 is located on the left side of the liquid storage box 131 and is arranged at intervals from the liquid storage box 131 and the atomizing element 132. In the process of the water mist entering the mist guide pipe 133 from the spray port through the mist guide port 136, a local negative pressure is formed in the space between the mist guide port 136 and the spray port, so that the surrounding air is drawn into the water mist. The air flow makes the water mist diffuse in the mist guide pipe 133 over a larger distance and a wider range, so that the water mist is evenly output to the accommodating chamber 111 through multiple mist outlet holes 135, so that the water mist is evenly diffused to the accommodating chamber 111, which is conducive to improving the atomization and humidification effect, without the need for a fan, and has a simple structure. In addition, the diffusion range of the water mist is increased by the flow of air, and a fan is not required, which is conducive to simplifying the structure and saving costs.

[0036] At the same time, since the mist guide pipe 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, there is no connection between the mist guide pipe 133 and the liquid storage box 131, and between the mist guide pipe 133 and the atomizing element 132, the structure is simple, and the liquid storage box 131 can be independently disassembled and assembled, which is convenient for installation and later maintenance.

[0037] Of course, in other embodiments, the mist guide tube 133 and the liquid storage box 131 may be in contact with or connected to each other, and it is only necessary to make the mist guide port 136 of the mist guide tube 133 correspond to the spray port and be arranged at intervals.

[0038] It is understood that the drawer body 110 includes a panel 112 located at the front end, and the panel 112 is a transparent part. The panel 112 is made of materials including plastic or glass, which can facilitate users to observe the placement of objects in the drawer. It is understood that the transparent part can be a fully transparent part with a transparency of 100% or a transparent part with a transparency of 30%, 50%, 80%, etc. The transparency of the panel 112 can be satisfied as long as the user can observe the inside of the accommodating cavity 111. It is understood that the mist guide pipe 133 is located at one end of the accommodating cavity 111 close to the panel 112. When the atomization module 130 is working, the user can easily observe the mist sprayed from the mist outlet 135 by the mist guide pipe 133 through the panel 112, so as to show the user an intuitive atomization effect. It is understood that the liquid storage box 131 is also arranged at one end of the accommodating cavity 111 close to the panel 112, so that the user can easily disassemble and assemble the liquid storage box 131, thereby realizing convenient water addition or cleaning operations.

[0039] Reference Figure 2 and Figure 4 It can be understood that the liquid storage box 131 is provided with an upper cover 138, and the liquid storage box 131 can be slidably installed on the cover body 103 along the front and rear directions. When the liquid storage box 131 is pulled out from the cover body 103, the upper cover 138 can be opened to add water or clean it, which is conducive to improving the convenience of daily maintenance.

[0040] It can be understood that the liquid storage box 131 is provided with 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 body 103 is provided with 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 flange 117 is inserted into the first sliding groove 118 and the bottom wall of the first flange 117 presses against the inner bottom wall of the first sliding groove 118, and the first flange 117 can slide in the first sliding groove 118, so that the liquid storage box 131 is slidably connected to the cover body 103.

[0041] It is understandable that the drawer assembly further includes an inner drawer 113, which is disposed in the accommodating cavity 111 and is located on the left side of the liquid storage box 131. The inner drawer 113 is slidably mounted on the cover body 103 along the front-rear direction. Specifically, the inner drawer 113 is provided with 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 body 103 is provided with 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 flange 119 is inserted into the second sliding groove 120, and the bottom wall of the second flange 119 is pressed against the inner bottom wall of the second sliding groove 120, and the second flange 119 can slide in the second sliding groove 120, so that the inner drawer 113 is slidably connected to the cover body 103.

[0042] It is understandable that, in the vertical direction, the thickness of the inner drawer 113 is equal to the thickness of the liquid storage box 131, so that the outer bottom wall of the inner drawer 113 and the liquid storage box 131 occupy the same height space of the accommodating cavity 111, thereby making the space in the accommodating cavity 111 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 separately provided, and the inner drawer 113 and the liquid storage box 131 can also move in the front-to-back direction, so that the two can be independently disassembled and assembled to avoid interference, which is conducive to simplifying the structure and facilitating daily maintenance.

[0043] Reference Figure 3 It can be understood that since the mist guide pipe 133 is arranged in the accommodating cavity 111 and installed at the front end of the cover body 103 close to the panel 112, the mist guide pipe 133 will occupy a certain height space of the accommodating cavity 111, and the drawer body 110 will move relative to the mist guide pipe 133 when opening and closing. If the fruits and vegetables in the accommodating cavity 111 occupy the space at the rear end of the mist guide pipe 133, the fruits and vegetables will interfere with the mist guide pipe 133 during the process of opening and closing the drawer body 110. Therefore, the space in the accommodating cavity 111 at the rear end of the mist guide pipe 133 is often not utilized, and the space utilization rate of the accommodating cavity 111 is insufficient.

[0044] Therefore, the mist guide pipe 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 pipe 133 will not protrude from the bottom of the inner drawer 113 to the accommodating cavity 111, which is beneficial for avoiding interference between the fruits and vegetables in the accommodating cavity 111 and the mist guide pipe 133 while making full use of the space at the rear end of the mist guide pipe 133, thereby improving the space utilization rate of the accommodating cavity 111.

[0045] Reference Fig.10 and Fig.11 It can be understood that the inner drawer 113 includes a handle 114 at the front end, and the handle 114 is used to pull the inner drawer 113 to open and close. The handle 114 is provided with a groove 115 with an opening facing downward, and the mist guide pipe 133 is located in the groove 115. On the one hand, it is conducive to the embedded installation of the mist guide pipe 133, which can save the space of the accommodating cavity 111; on the other hand, since the handle 114 is provided at the front end of the inner drawer 113, the mist guide pipe 133 is installed in the groove 115 to ensure that the mist guide pipe 133 is located at the front end of the accommodating cavity 111 close to the panel 112, so that the user can observe the water mist sprayed by the mist guide pipe 133 and realize the intuitive display of the humidification process.

[0046] It is understandable that the mist guide pipe 133 is detachably connected to the inner drawer 113. For example, the mist guide pipe 133 is detachably installed in the groove 115 by snapping; or the mist guide pipe 133 can be installed and fixed by bolt connection, adhesive connection, etc., to facilitate daily maintenance.

[0047] In other embodiments, the mist guide tube 133 is formed in the inner drawer 113 and forms an integral structure with the inner drawer 113. The mist guide tube 133 and the inner drawer 113 can be integrally injection molded, which is beneficial to simplify the structure, reduce the installation steps, and thus improve production efficiency.

[0048] Reference Figure 3 and Fig.11 , the atomization module 130 also includes a light source 137, which can be an LED lamp. The light source 137 is arranged in the accommodating chamber 111 and at least illuminates the mist outlet side of the mist outlet hole 135. It can be understood that the mist outlet hole 135 is arranged on the bottom wall of the mist guide pipe 133, and the axis of the mist outlet hole 135 extends in the vertical direction, so the water mist is sprayed from the bottom of the mist guide pipe 133, and the mist outlet side of the mist outlet hole 135 is the space below the mist guide pipe 133 in the accommodating chamber 111. The light of the light source 137 is irradiated on the mist outlet side. At the same time, with the help of the fully transparent or translucent panel 112, the light source 137 is irradiated on the water mist output from the mist outlet hole 135, so that the process of atomization and humidification can be displayed, which is conducive to improving the user experience.

[0049] It is understandable that the light source 137 is installed on any side of the mist guide tube 133 along the front-to-back direction. In this embodiment, the light source 137 is installed on the rear side of the mist guide tube 133. Further, the rear side of the mist guide tube 133 has a mounting portion 140 extending backwards, and the light source 137 is installed on the mounting portion 140.

[0050] In other embodiments, the light source 137 is embedded in the groove 115 so that the light source 137 does not protrude from the accommodating cavity 111 , which helps to avoid interference between the light source 137 and the fruits and vegetables in the accommodating cavity 111 .

[0051] It is understandable that when the user opens the door, or in demonstration mode, the atomizing element 132 is started, and the light source 137 is turned on and illuminates the mist outlet side, so that the user can easily observe the water mist discharged from the mist guide pipe 133, with a good display effect. During the normal operation of the refrigerator at the user end, when the user closes the door, the atomizing element 132 is periodically started, and the light source 137 is turned off, which is conducive to achieving energy saving while ensuring the humidification effect. Among them, the atomizing element 132 can be periodically started according to the humidity value in the accommodating cavity 111 detected by the humidity sensor arranged in the accommodating cavity 111. For example, the atomizing element 132 is started when the humidity sensor detects that the humidity value in the accommodating cavity 111 is low, and the atomizing element 132 stops working when the humidity value is high. Or the atomizing element 132 is started regularly to achieve periodic startup.

[0052] Reference Figure 3 and Figure 5The mist guide pipe 133 has a plurality of mist outlet holes 135 arranged at intervals along its length direction, and the spacing between two adjacent mist outlet holes 135 is b, which satisfies 5mm≤b≤50mm. It can be understood that the spacing b between two adjacent mist outlet holes 135 is the center distance between two adjacent mist outlet holes 135.

[0053] It can be understood that multiple mist outlet holes 135 are evenly arranged in the mist guide pipe 133. Under the premise that the length of the mist guide pipe 133 is certain, when b is less than 5 mm, the distance between two adjacent mist outlet holes 135 is too small, resulting in a large number of mist outlet holes 135. The mist outlet holes 135 are arranged too densely in the mist guide pipe 133, so that most of the water mist is discharged from the mist outlet holes 135 close to the atomizing element 132, and only a small part is discharged from the mist outlet holes 135 far away from the atomizing element 132, which leads to uneven mist discharge from the mist guide pipe 133, and inconsistent humidification of fruits and vegetables located at different positions, affecting the humidification effect. When b is greater than 50mm, the distance between two adjacent mist outlet holes 135 is too large, resulting in an insufficient number of mist outlet holes 135, and the arrangement of the mist outlet holes 135 in the mist guide pipe 133 is too sparse, which will cause part of the water mist to fail to be discharged through the mist outlet holes 135 in time and gather into water droplets in the mist guide pipe 133, resulting in poor atomization effect, affecting the humidification effect, and even causing water to accumulate in the mist guide pipe 133 and be discharged through the mist outlet holes 135, thereby causing water to accumulate in the inner drawer 113. Therefore, when the spacing b between two adjacent mist outlet holes 135 satisfies 5mm≤b≤50mm, it can ensure uniform mist discharge from the mist guide pipe 133 and achieve good atomization effect, thereby ensuring a good humidification effect and avoiding dripping and water accumulation.

[0054] It is understood that in this embodiment, the mist outlet hole 135 can be set to a circular, rectangular or polygonal shape. At the same time, the inner diameter of the mist outlet hole 135 is d, which satisfies 1mm≤d≤10mm. It is understood that the inner diameter d of the mist outlet hole 135 is the minimum inner diameter of the mist outlet hole 135, and the minimum inner diameter is twice the minimum distance between the inner circumferential wall of the mist outlet hole 135 and its axis.

[0055] It is understandable that when the inner diameter d of the mist outlet hole 135 is less than 1 mm, the size of the mist outlet hole 135 is too small, which will cause part of the water mist to fail to be discharged through the mist outlet hole 135 in time and gather into water droplets in the mist guide tube 133, resulting in poor atomization effect, affecting the humidification effect, and even causing water to accumulate in the mist guide tube 133 and drip through the mist outlet hole 135, thereby causing water to accumulate in the inner drawer 113. When the inner diameter d of the mist outlet hole 135 is greater than 10 mm, the size of the mist outlet hole 135 is too large, causing most of the water mist to be discharged from the mist outlet hole 135 close to the atomizing element 132, and only a small part of it to be discharged from the mist outlet hole 135 far away from the atomizing element 132, resulting in uneven mist discharge from the mist guide tube 133, inconsistent humidification of fruits and vegetables located at different positions, and affecting the humidification effect. Therefore, when the inner diameter d of the mist outlet hole 135 satisfies 1mm≤d≤10mm, it can ensure that the mist guide pipe 133 can emit mist evenly and achieve a good atomization effect, thereby ensuring a good humidification effect and avoiding dripping and water accumulation.

[0056] It can be understood that, in this embodiment, the distance b between two adjacent mist outlet holes 135 satisfies 5 mm ≤ b ≤ 50 mm, and the inner diameter d of the mist outlet hole 135 satisfies 1 mm ≤ d ≤ 10 mm.

[0057] It is understandable that when b is less than 5 mm and d is less than 1 mm, on the one hand, the distance between two adjacent mist outlet holes 135 is too small, resulting in a large number of mist outlet holes 135, and the mist outlet holes 135 are arranged too densely in the mist guide pipe 133, so that most of the water mist is discharged from the mist outlet holes 135 close to the atomizing element 132, and only a small part is discharged from the mist outlet holes 135 far away from the atomizing element 132, thereby causing the mist outlet of the mist guide pipe 133 to be uneven, and the humidification of fruits and vegetables located at different positions is inconsistent, affecting the humidification effect. On the other hand, if the size of the mist outlet hole 135 is too small, part of the water mist will not be discharged through the mist outlet hole 135 in time, but will gather into water droplets in the mist guide pipe 133, resulting in poor atomization effect, affecting the humidification effect, and even causing water to accumulate in the mist guide pipe 133 and drip through the mist outlet hole 135, thereby causing water to accumulate in the inner drawer 113. In general, when the aperture and hole spacing are too small, it is easy to lead to poor atomization effect, uneven mist distribution and poor humidification effect.

[0058] When b>50mm and d>10mm, on the one hand, the distance between two adjacent mist outlet holes 135 is too large, resulting in an insufficient number of mist outlet holes 135, and the arrangement of the mist outlet holes 135 in the mist guide pipe 133 is too sparse, which will cause part of the water mist to fail to be discharged through the mist outlet holes 135 in time and gather into water droplets in the mist guide pipe 133, resulting in poor atomization effect, affecting the humidification effect, and even causing water accumulation in the mist guide pipe 133 and being discharged through the mist outlet holes 135, thereby causing water accumulation in the inner drawer 113. On the other hand, the size of the mist outlet holes 135 is too large, so that most of the water mist is discharged from the mist outlet holes 135 close to the atomizing element 132, and only a small part is discharged from the mist outlet holes 135 far away from the atomizing element 132, resulting in uneven mist discharge from the mist guide pipe 133, inconsistent humidification of fruits and vegetables located at different positions, affecting the humidification effect. In summary, when the aperture and the hole spacing are too large, most of the water mist is easily discharged from the mist outlet holes 135 close to the atomizing element 132, that is, only a small part of the mist outlet holes 135 can discharge the water mist, resulting in uneven mist discharge and poor humidification effect.

[0059] When b is less than 5 mm and d is greater than 10 mm, that is, the distance between two adjacent mist outlet holes 135 is less than the radius of the mist outlet hole 135, the multiple mist outlet holes 135 arranged along the axial direction of the mist guide pipe 133 overlap in sequence, forming a through groove extending along the axial direction of the mist guide pipe 133, and the through groove connects the mist guide pipe 133 and the accommodating chamber 111, which will cause the water mist to be mainly discharged from one end of the through groove close to the atomizing element 132, resulting in uneven mist discharge from the mist guide pipe 133 and poor humidification effect.

[0060] When b>50mm and d<1mm, that is, the distance between two adjacent mist outlet holes 135 is too large and the inner diameter of the mist outlet hole 135 is too small, so that the total area of ​​the mist outlet holes 135 on the mist guide pipe 133 is too small, resulting in that part of the water mist cannot be discharged in time and gathers into water droplets in the mist guide pipe 133, the atomization effect is poor, and the humidification effect is affected, and even water accumulation is generated in the mist guide pipe 133 and discharged through the mist outlet hole 135, thereby causing water accumulation in the inner drawer 113.

[0061] Therefore, when the spacing b between two adjacent mist outlet holes 135 satisfies 5mm≤b≤50mm, and the inner diameter d of the mist outlet hole 135 satisfies 1mm≤d≤10mm, it can ensure that the mist guide pipe 133 emits mist evenly and achieves a good atomization effect, thereby ensuring a good humidification effect and avoiding dripping and water accumulation.

[0062] Reference Figure 6 The minimum distance a between the mist guide tube 133 and the atomizing element 132 is 5 mm ≤ a ≤ 50 mm. 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 axis of the mist guide tube 133 .

[0063] It is understandable that when a is less than 5 mm, the distance between the mist guide tube 133 and the atomizing element 132 is too small, and sufficient air cannot be drawn in, resulting in difficulty in fully diffusing the water mist in the mist guide tube 133, thereby resulting in poor atomization effect and affecting the humidification effect. When a is greater than 50 mm, the distance between the mist guide tube 133 and the atomizing element 132 is too large, resulting in a portion of the water mist not entering the mist guide tube 133 but directly floating into the accommodating chamber 111, so that the water mist is mainly concentrated in the part of the mist guide tube 133 close to one end of the atomizing element 132, resulting in uneven spraying and poor humidification effect. Therefore, when the minimum distance a between the mist guide tube 133 and the atomizing element 132 satisfies 5 mm ≤ a ≤ 50 mm, the water mist is drawn in with sufficient air and fully diffused in the mist guide tube 133, and is discharged into the accommodating chamber 111 through the mist outlet hole 135, achieving a uniform atomization and humidification effect.
