Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a refrigerator. Background Technology

[0002] In the current technology, air-cooled refrigerators are widely used due to their frost-free characteristics. Air-cooled refrigerators have continuously circulating cold air, so unlike direct-cooling refrigerators, the inside of an air-cooled refrigerator is not always damp, food does not stick together, and the interior odor remains fresh for a long time.

[0003] However, because the cold air in the frost-free refrigerator is constantly circulating and blowing towards every corner of the refrigerator, as the storage time of fruits, vegetables and other foods in the refrigerator is extended, the food is constantly being blown by the cold air, causing the food to lose moisture or even dry out, making the food no longer fresh. Current humidifiers have removable water tanks for easy refilling, but the humidifying components and other parts cannot be disassembled, making repairs inconvenient if damaged. Summary of the Invention

[0004] This application provides a refrigerator in which the humidifying element and water storage box of the humidifying device can be disassembled and installed, which facilitates the maintenance and installation of the humidifying device.

[0005] In a first aspect, a refrigerator is provided, comprising: The container defines the storage compartment; A drawer unit located within the storage compartment; the drawer unit includes: The drawer body has a receiving cavity with a receiving opening; A cover plate is provided at the receiving opening of the receiving cavity; A humidifying device is used to humidify the accommodating cavity; the humidifying device includes: The mounting base is disposed on the cover plate and located on the side of the cover plate near the receiving cavity; A water storage box, which is detachably connected to the mounting base, is used to hold humidification water; A humidifier is located on the side of the mounting base away from the cover plate and is detachably connected to the mounting base.

[0006] The above technical solution has two advantages. First, the humidifier and the mounting base are detachably connected, which facilitates repair when the humidifier is damaged. Second, the humidifier is located on the side of the mounting base away from the cover plate, so that the humidifier is located on the lower side of the mounting base, providing a large enough operating space for maintenance. It can be directly disassembled or installed from the side of the mounting base away from the cover plate without operating the mounting base. The disassembly and installation operations are simple and convenient for maintenance.

[0007] The water storage box and the mounting base are detachably connected, which facilitates repair when the water storage box is damaged, and also makes it easy to refill the water storage box after it is removed.

[0008] In some embodiments, the mounting base is provided with a humidification chamber; the humidification chamber has a first communicating hole on its cavity wall opposite to the cover plate; The humidifying element is located on the side of the first connecting hole away from the cover plate; When the water storage box is installed on the mounting base, the water storage box is connected to the humidification chamber, and the water in the water storage box enters the humidification chamber and comes into contact with the humidification component through the first connecting hole.

[0009] In the above technical solutions, since the humidifier humidifies the accommodating cavity of the drawer body located below it through the humidifying element, the water supply component of the humidifier is usually located above it. If the humidifier is directly connected to the water storage box so that the water in the water storage box directly supplies water to the humidifier, then the humidifier and the water storage box are fixedly connected. However, to reduce the size of the humidifier, atomization humidification is used; however, the humidifier of the atomization humidification method is connected to the wire, and the humidifier should not be repeatedly disassembled and reassembled, so it needs to be fixedly connected to the cover. Therefore, the water storage box needs to be fixedly connected to the cover. Since the water storage box is located on the lower side of the cover, water cannot be added from the top of the water storage box, or the cover needs to be modified accordingly to add water from the top of the water storage box; adding water from the side or bottom of the water storage box increases the difficulty and complexity of adding water. In the technical solution of this application, the water in the water storage box supplies water to the humidifier through the humidification chamber, making the water storage box detachable and increasing the flexibility and ease of water replenishment.

[0010] In some embodiments, the mounting base is provided with a fixing member, which is detachably connected to the cavity wall of the humidification chamber; the humidification component is sandwiched between the fixing member and the mounting base.

[0011] The above technical solution uses a fastener to clamp the humidifier between the fastener and the wall of the humidification chamber to fix the humidifier. On the one hand, this ensures the integrity of the humidifier, as it can be fixed without physical damage. On the other hand, the fastener and the wall of the humidification chamber are detachably connected, allowing the humidifier to be disassembled and reassembled by removing and installing the fastener, which is convenient for replacing parts during maintenance.

[0012] In some embodiments, the humidification chamber has a first receiving cavity with a first mounting opening on the side of its cavity wall away from the cover plate, the first mounting opening facing the side away from the cover plate; The humidifier is installed in the first receiving cavity, and the fixing member cooperates with the cavity wall of the first receiving cavity to fix the humidifier on the mounting base.

[0013] In the above technical solution, the fixing component cooperates with the cavity wall of the humidification chamber to hold the humidification component flat between the two, thereby limiting the position of the humidification component in the direction perpendicular to the cover plate; the first mounting opening of the first receiving cavity faces the side away from the cover plate, and the first receiving cavity limits and defines the position of the humidification component in a plane parallel to the cover plate; the fixing component cooperates with the cavity wall of the first receiving cavity to fix the humidification component on the mounting base, ensuring the accuracy of the installation position and avoiding insufficient contact between the water in the humidification chamber and the humidification component, thus reducing the humidification effect.

[0014] In some embodiments, the mounting base is provided with a second receiving cavity having a second mounting opening; the second mounting opening faces the side opposite to the cover plate; The humidification device includes a control board electrically connected to the humidification element, the control board being detachably installed in the second receiving cavity.

[0015] In the above technical solution, the control board connected to the humidifier is detachably installed on the mounting base, so that it is convenient to disassemble and repair or install a new control board when the control board is damaged.

[0016] In some embodiments, the storage compartment has an access opening disposed opposite its rear wall; The humidification chamber has a docking channel on its wall near the inlet / outlet; The water storage box includes a docking joint at one end near the rear wall of the storage chamber; the docking joint is provided with a first sealing element; When the water storage box is installed on the mounting base, the docking joint is installed in the docking channel, and the first sealing element is sealed and fitted with the docking channel.

[0017] In the above technical solution, when the water storage box is installed on the mounting base, the mating joint is installed inside the mating channel, and the first sealing element is sealed and fitted with the mating channel. This technical solution, on the one hand, prevents water leakage when water from the water storage box enters the humidification chamber through the mating joint; on the other hand, the sealed fit between the first sealing element and the mating channel increases the connection strength between the mating joint and the mating channel, thus forming a fixed position for securing the water storage box and the mounting base at the connection point.

[0018] In some embodiments, the mounting base has two mounting slots; each of the mounting slots extends along a direction from the access port toward the rear wall of the storage compartment; The two opposite ends of the water storage box are detachably installed in the mounting slots.

[0019] The above technical solution allows for the detachable connection between the mounting slots on the mounting base and the opposite ends of the water storage box to secure the water storage box. Combined with the sealing fit between the docking joint located at the end of the water storage box near the rear wall of the storage chamber and the docking channel, the water storage box is firmly installed on the mounting base, improving the overall integrity and stability of the humidification device.

[0020] In some embodiments, in the projection of the cover plate on the side surface near the drawer body, the minimum distance between any one of the mounting slots and the central axis of the mating joint is denoted as the first distance D1, and the minimum distance between the other mounting slot and the central axis of the mating joint is denoted as the second distance D2. Wherein, the first distance D1 = the second distance D2.

[0021] The above technical solution, where the first distance D1 equals the second distance D2, ensures that the connection points between the two mounting slots and the water storage box form locking points symmetrical to the connection points between the docking joint and the docking channel. The three connection points form the distribution of the three vertices of an isosceles triangle, enhancing the connection strength between the water storage box and the mounting base and improving the overall integrity and stability of the humidification device. In addition, it allows the water storage box to be pulled out by applying force only along the central axis of the docking joint, thus completing the disassembly of the water storage box.

[0022] In some embodiments, the mounting base is provided with a third receiving cavity having a third mounting opening; the third mounting opening faces the side opposite to the cover plate; The refrigerator includes a preservation light, which is detachably installed in the third accommodating cavity; The third mounting port is provided with a cover, which is detachably connected to the cavity wall of the third receiving cavity.

[0023] In the above technical solution, the preservation lamp is located in the third accommodating cavity on the mounting base, which facilitates the centralized routing of the wiring harness connected to the power supply. In addition, the preservation lamp is detachably installed in the third accommodating cavity, which makes it convenient to disassemble and repair or install a new preservation lamp when the preservation lamp is damaged.

[0024] Secondly, a refrigerator is provided, comprising: The container defines the storage compartment; A drawer unit located within the storage compartment; the drawer unit includes: The drawer body has a receiving cavity with a receiving opening; A cover plate is provided at the receiving opening of the receiving cavity; A humidifying device is used to humidify the accommodating cavity; the humidifying device includes: The mounting base is disposed on the cover plate and located on the side of the cover plate near the receiving cavity; A humidifying element is disposed on the side of the mounting base away from the cover plate and is detachably connected to the mounting base; A humidification chamber, formed on the mounting base, is used to supply water to the humidification element; A water storage box has a water outlet that communicates with the humidification chamber; the water storage box is detachably connected to the cavity wall of the humidification chamber, so that water in the water storage box can enter the humidification chamber through the water outlet; The bottom of the water storage box protrudes away from the cover plate; wherein the point at which the bottom of the water storage box is furthest from the cover plate is adjacent to the water outlet of the water storage box.

[0025] The above technical solution has two advantages. First, the humidifier and the mounting base are detachably connected, which facilitates repair when the humidifier is damaged. Second, the humidifier is located on the side of the mounting base away from the cover plate, so that the humidifier is located on the lower side of the mounting base, providing a large enough operating space for maintenance. It can be directly disassembled or installed from the side of the mounting base away from the cover plate without operating the mounting base. The disassembly and installation operations are simple and convenient for maintenance.

[0026] The water storage box is detachably connected to the humidification chamber wall on the mounting base. This facilitates repairs when the water storage box is damaged and allows for water replenishment after the water storage box is removed.

[0027] The point at which the bottom of the water storage box is furthest from the cover is adjacent to the water outlet of the water storage box, so that the water in the water storage box flows into the humidification chamber through the water outlet of the water storage box as much as possible, thereby reducing the amount of water stored in the water storage box and improving the utilization rate of the water in the water storage box.

Detailed Implementation

[0030] To make the objectives and implementation methods of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the exemplary embodiments described are only some embodiments of this application, and not all embodiments.

[0031] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0032] The terms "first," "second," "third," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar or related objects or entities, and do not necessarily imply a specific order or sequence, unless otherwise specified. It should be understood that such terms are interchangeable where appropriate.

[0033] The terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclude inclusion, for example, a product or device that includes a range of components is not necessarily limited to all of the components that are clearly listed, but may include other components that are not clearly listed or that are inherent to such product or device.

[0034] Please refer to Figures 1-5 The refrigerator 100 includes a cabinet 101, which defines a storage compartment 102. The front end of the storage compartment 102 has a loading / unloading opening 103 for placing stored items into or retrieving stored items from the storage compartment 102 through the loading / unloading opening 103.

[0035] The refrigerator 100 includes a door that is connected to the cabinet 101 to open and close the storage compartment 102. The door is rotatably connected to the cabinet 101 to open or close the access port 103.

[0036] The refrigerator 100 includes a refrigeration unit that supplies cold air to the storage compartment 102 to regulate the temperature inside the storage compartment 102 and create a low-temperature storage environment suitable for food preservation.

[0037] In some embodiments of this application, the refrigerator 100 includes a drawer unit 1 disposed in the storage compartment. The drawer unit 1 includes a drawer body 11 defining a receiving cavity 12a having a storage opening 12 for a user to place retrievable storage items when the drawer body 11 is pulled out.

[0038] In some embodiments of this application, the drawer unit 1 includes a cover 13. When the drawer body 11 is installed in the storage compartment, the cover 13 is located at the storage opening 12 of the receiving cavity 12a to close the storage opening 12. In the above technical solutions, the cover 13 and the drawer body 11 together define a smaller storage space that is relatively independent of the storage compartment, allowing for targeted control of this smaller storage space to form a relatively independent storage environment.

[0039] In some embodiments of this application, the cover plate 13 is connected to the wall of the storage compartment to fix the cover plate 13. When the drawer body 11 is pulled out of the storage compartment, the cover plate 13 remains stationary relative to the storage compartment. In the above technical solution, the cover plate 13 is fixed to the wall of the storage compartment and does not move as the drawer body 11 is pulled out, allowing the drawer body 11 to directly open its storage opening 12 when pulled out, facilitating the retrieval and placement of stored items. Furthermore, the cover plate 13 remains located within the storage compartment, and the upper layer of the cover plate 13 can be used to place stored items within the storage compartment, thereby improving space utilization.

[0040] In some embodiments of this application, the refrigerator 100 includes a humidifying device 2. The humidifying device 2 is used to humidify the accommodating cavity 12a to replenish the moisture of food placed in the drawer body 11 and prevent the food from drying out.

[0041] In some embodiments of this application, the humidifying device 2 includes a mounting base 21. The mounting base 21 is disposed on the cover plate 13 and located on the side of the cover plate 13 near the receiving cavity 12a. The mounting base 21 is used to mount other components of the humidifying device 2 besides the mounting base 21. This technical solution allows the humidifying device 2 to be mounted on the side of the cover plate 13 near the receiving cavity 12a, thereby specifically humidifying the receiving cavity 12a and creating a humidity environment independent of the storage room, thus improving the preservation effect of the stored items located in the drawer body 11.

[0042] Please refer to Figures 6-8 In some embodiments of this application, the humidifying device 2 includes a humidifying element 22 mounted on a mounting base 21. The humidifying element 22 is located on the side of the mounting base 21 away from the cover plate 13 and is used to replenish water into the accommodating cavity 12a. The humidifying element 22 is detachably connected to the mounting base 21. This technical solution, on the one hand, facilitates repair when the humidifying element 22 is damaged; on the other hand, the location of the humidifying element 22 on the side of the mounting base 21 away from the cover plate 13 provides sufficient operational space for repair, allowing for direct removal or installation from the side of the mounting base 21 away from the cover plate 13 without requiring operation of the mounting base 21. This simplifies the removal and installation process and facilitates maintenance.

[0043] In some embodiments of this application, the humidifying device 2 includes a water storage box 23, which is used to supply water to the humidifying element 22. The water storage box 23 is detachably connected to the mounting base 21 and is used to hold the humidifying water. In this technical solution, the detachable connection between the water storage box 23 and the mounting base 21 facilitates repair in case of damage to the water storage box 23, and also facilitates refilling the water storage box 23 after disassembly.

[0044] In some embodiments of this application, the humidifier 22 is configured as an atomizing humidifier 22. The humidification device 2 utilizes ultrasound for atomization. Specifically, ultrasonic atomization technology is a technique that uses the high-frequency vibration energy of ultrasound to break down liquids into tiny particles, forming a mist. Its basic principle is that the ultrasonic transducer generates high-frequency vibrations under the drive of an electrical signal, transferring vibrational energy to the liquid, causing tiny bubbles to form on or inside the liquid surface. These bubbles rapidly grow under the action of ultrasound and eventually burst, releasing mist-like droplets. With the above technical solution, on the one hand, the humidifier 22 occupies little space, and the atomized humidification results in more uniform humidification, reducing condensation and preventing mold growth on stored goods. On the other hand, although the humidification source area is small, the atomized humidification area is large, resulting in high humidification efficiency.

[0045] Please refer to some embodiments of this application. Figures 9-11 The bottom of the water storage box 23 protrudes away from the cover plate 13; the point where the distance between the bottom of the water storage box 23 and the cover plate 13 is the greatest is adjacent to the water outlet 231a of the water storage box 23.

[0046] In the above technical solution, the point where the distance between the bottom of the water storage box 23 and the cover plate 13 is the greatest is adjacent to the water outlet 231a of the water storage box 23, so that the water in the water storage box 23 flows into the humidification chamber 211 through the water outlet 231a of the water storage box 23 as much as possible, thereby reducing the amount of water stored in the water storage box 23 and improving the utilization rate of the water in the water storage box 23.

[0047] Please refer to some embodiments of this application. Figure 12 The humidifying device 2 includes a humidifying chamber 211; a first communicating hole is provided on the chamber wall of the humidifying chamber 211 opposite to the cover plate 13; the humidifying element 22 is located on the side away from the cover plate 13 from the first communicating hole. When the water storage box 23 is installed on the mounting base 21, the water storage box 23 is connected to the humidifying chamber 211, and the water in the water storage box 23 enters the humidifying chamber 211 and comes into contact with the humidifying element 22 through the first communicating hole.

[0048] In the above technical solutions, since the humidifier 2 humidifies the accommodating cavity 12a of the drawer body 11 located below it through the humidifier 22, the water supply component of the humidifier 22 is usually located above it. If the humidifier 22 is directly connected to the water storage box 23 so that the water in the water storage box 23 can directly supply water to the humidifier 22, then the humidifier 22 and the water storage box 23 are fixedly connected. However, in order to reduce the size of the humidifier 2, atomization humidification is adopted; and the humidifier 22 of the atomization humidification method is connected to the wire, and the humidifier 22 should not be repeatedly disassembled and reassembled, so it needs to be fixedly connected to the cover plate 13. Therefore, the water storage box 23 needs to be fixedly connected to the cover plate 13. Since the water storage box 23 is located on the lower side of the cover plate 13, the water storage box 23 cannot be filled with water from the top or the cover plate 13 needs to be modified accordingly to fill water from the top of the water storage box 23; if water is filled from the side or bottom of the water storage box 23, the difficulty and complexity of filling water are increased. In the above technical solution of this application, the water in the water storage box 23 is supplied to the humidifying component 22 through the humidifying chamber 211, which makes the water storage box 23 detachable and increases the flexibility and ease of water replenishment.

[0049] Please refer to some embodiments of this application. Figures 6-8 The mounting base 21 is provided with a fixing member 4, which is detachably connected to the cavity wall of the humidification chamber 211; the humidifying component 22 is sandwiched between the fixing member 4 and the mounting base 21.

[0050] The above technical solution uses the fastener 4 to clamp the humidifier 22 between the two walls of the humidifier chamber 211 to fix the humidifier 22. On the one hand, it ensures the integrity of the humidifier 22 and can be fixed without physical damage to the humidifier 22. On the other hand, the fastener 4 is detachably connected to the wall of the humidifier chamber 211, so that the humidifier 22 can be disassembled and assembled by removing and assembling the fastener 4, which is convenient for replacing parts during maintenance.

[0051] Please refer to some embodiments of this application. Figure 14 The humidifying chamber 211 has a first receiving chamber 21a with a first mounting opening on the side of the chamber wall away from the cover plate 13. The first mounting opening faces the side away from the cover plate 13. The humidifying component 22 is installed in the first receiving chamber 21a. The fixing component 4 cooperates with the chamber wall of the first receiving chamber 21a to fix the humidifying component 22 on the mounting base 21.

[0052] In the above technical solution, the fixing member 4 cooperates with the cavity wall of the humidification chamber 211 to hold the humidifying member 22 flat between them, thereby limiting the position of the humidifying member 22 in the direction perpendicular to the cover plate 13; the first mounting opening of the first receiving cavity 21a faces away from the cover plate 13, and the first receiving cavity 21a restricts and limits the position of the humidifying member 22 in the plane parallel to the cover plate 13; the fixing member 4 cooperates with the cavity wall of the first receiving cavity 21a to fix the humidifying member 22 on the mounting base 21, ensuring the accuracy of the installation position and avoiding insufficient contact between the water in the humidification chamber 211 and the humidifying member 22, thus reducing the humidification effect.

[0053] Please refer to some embodiments of this application. Figure 6 A second sealing element 32 is provided between the humidifying element 22 and the cavity wall of the humidifying chamber 211. A second connecting hole is formed on the second sealing element 32, which communicates with the first connecting hole. The humidifying element 22 is located on the side of the second connecting hole away from the cover plate 13. The fixing element 4 cooperates with the cavity wall of the humidifying chamber 211 to fix the second sealing element 32 and the humidifying element 22 to the mounting base 21.

[0054] The above technical solution includes a second sealing element 32 between the humidifying element 22 and the cavity wall of the humidifying chamber 211. The second sealing element 32 is an elastic element. On the one hand, it enables the humidifying element 22 to be installed in a sealed manner to prevent water leakage from the humidifying chamber 211. On the other hand, the second sealing element 32 has elastic deformation capability to prevent the humidifying element 22 from being fixed too tightly to the cavity wall of the humidifying chamber 211, which would cause poor vibration of the humidifying element 22, reduce the spraying effect, or cause the spraying to fail.

[0055] In some embodiments of this application, the compression dimension of the second seal 32 is denoted as the compression amount Y, where 3mm < Y ≤ 7mm.

[0056] In the above technical solutions, when Y < 3mm, the compression of the second seal 32 is too small, the sealing effect of the second seal 32 is poor, and the humidification chamber 211 is prone to leakage.

[0057] When Y > 7mm, the compression of the second seal 32 is too large. The second seal 32 in this state has poor deformability, resulting in poor vibration effect of the humidifier 22, reducing the spraying effect or causing it to fail to spray.

[0058] When 3mm < Y ≤ 7mm, on the one hand, the humidifier 22 can be installed in a sealed manner to prevent water leakage from the humidifier chamber 211; on the other hand, the second sealing element 32 in this state still has elastic deformation ability, so as to prevent the humidifier 22 from being fixed too tightly to the cavity wall of the humidifier chamber 211, which would cause poor vibration of the humidifier 22, reduce the spraying effect or cause it to fail to spray.

[0059] Please refer to some embodiments of this application. Figure 14The mounting base 21 has a second receiving cavity 21b with a second mounting opening; the second mounting opening faces away from the cover plate 13; the humidifying device 2 includes a control board 5 electrically connected to the humidifying element 22, and the control board 5 is detachably installed in the second receiving cavity 21b. In this technical solution, the control board 5 connected to the humidifying element 22 is detachably installed on the mounting base 21, so that it is convenient to disassemble and repair or install a new control board 5 if it is damaged.

[0060] Please refer to some embodiments of this application. Figure 14 The first receiving cavity 21a and the second receiving cavity 21b are arranged adjacent to each other. A first limiting groove 218 is provided on the side of the first receiving cavity 21a closest to the second receiving cavity 21b, and the first limiting groove 218 connects the first receiving cavity 21a and the second receiving cavity 21b. The control board 5 is connected to the humidifying element 22 via a first wire 91, which is installed within the first limiting groove 218. This technical solution connects the first receiving cavity 21a and the second receiving cavity 21b via the first limiting groove 218, allowing the installation of the first wire 91 connecting the control board 5 and the humidifying element 22. This reduces the length of the first wire 91 and fixes it in place, preventing displacement that could lead to poor contact and prevent the control board 5 from controlling the humidifying element 22 to work properly.

[0061] Please refer to some embodiments of this application. Figure 6 , Figures 12-13 The humidification chamber 211 has a docking channel 212 on its wall near the inlet / outlet 103; the water storage box 23 includes a docking connector 231 at one end near the rear wall of the storage chamber; the docking connector 231 is provided with a first sealing element 31; when the water storage box 23 is installed on the mounting base 21, the docking connector 231 is installed in the docking channel 212, and the first sealing element 31 is sealed and fitted with the docking channel 212. In the above technical solution, when the water storage box 23 is installed on the mounting base 21, the docking connector 231 is installed in the docking channel 212, and the first sealing element 31 is sealed and fitted with the docking channel 212.

[0072] Please refer to some embodiments of this application. Figure 14 The first receiving cavity 21a and the second receiving cavity 21b are arranged along the extension direction of the rear end of the cover plate 13; the third receiving cavity 21c is located on the side of the first receiving cavity 21a and the second receiving cavity 21b away from the rear end wall of the cover plate 13. With the above technical solution, the arrangement of the first receiving cavity 21a, the second receiving cavity 21b, and the third receiving cavity 21c is concentrated, the structure is more compact, the volume of the humidifying device 2 is reduced, thereby reducing the space occupied by the humidifying device 2 and improving space utilization.

[0073] Please refer to some embodiments of this application. Figure 14 The third receiving cavity 21c is arranged adjacent to the second receiving cavity 21b, and a first wiring hole 219 is provided on the cavity wall separating the third receiving cavity 21c and the second receiving cavity 21b. The control board 5 is connected to the preservation lamp 7 through a second wire, which is installed in the first wiring hole 219. In the above technical solution, the adjacent arrangement of the third receiving cavity 21c and the second receiving cavity 21b makes the preservation lamp 7 adjacent to the control board 5, reduces the length of the second wire, and restricts the position of the second wire to avoid poor connection due to large changes in its position, which would prevent the control board 5 from controlling the preservation lamp 7 to work normally.

[0074] In some embodiments of this application, a power supply unit is provided on the rear wall of the storage compartment; a wiring trough 8 is provided on the side of the cover plate 13 near the drawer body 11; the wiring trough 8 extends from the access port 103 toward the rear wall of the storage compartment. The humidification device 2 includes a third wire 92 for connection to the power supply unit, and the third wire 92 is installed in the wiring trough 8.

[0075] The above technical solution involves providing a wiring groove 8 on the cover plate 13 to fix the third wire 92 of the humidifier 2, which is used to connect to the power supply. On one hand, this hides the third wire 92, preventing it from interfering with stored items and being damaged when retrieving them, thus ensuring the effective operation of the humidifier 22. On the other hand, it protects the third wire 92, reducing the impact of temperature and humidity within the accommodating cavity 12a defined by the drawer body 11 on the lifespan of the third wire 92 and improving product safety. Furthermore, the wiring groove 8 allows for… The humidifier 2 can be positioned near the access port 103 relative to the rear wall of the storage compartment. This increases the drawer's extension range without reducing the height of the rear wall of the drawer body 11, making it easier to access stored items. In addition, the wiring trough 8 allows the humidifier 2 to be positioned in the middle area along the direction from the access port 103 toward the rear wall of the storage compartment. This allows the humidifier to humidify the accommodating cavity 12a defined by the drawer body 11 from the middle area at its top, improving the uniformity of humidification and preventing uneven humidification from causing excessive moisture and condensation that could lead to mold growth on stored items.

[0076] Please refer to some embodiments of this application. Figures 6-8 A retaining strip 6 is provided at one end of the cover plate 13 near the rear wall of the storage compartment. The retaining strip 6 includes a first retaining groove 61, which engages with the end of the cover plate 13 near the rear wall of the storage compartment. The retaining strip 6 also includes a second retaining groove 62, located on the side of the first retaining groove 61 near the drawer body 11. A third guide wire 92 is installed within the second retaining groove 62.

[0077] The above technical solution involves providing a second slot 62 for installing the third wire 92 on the retaining strip 6 at the rear end of the cover plate 13. The third wire 92, connected to the humidifier 22, passes through the humidifier 2 and is first installed in the wiring groove 8 on the cover plate 13, and then installed in the second slot 62. This guides the third wire 92 of the humidifier 2, which is used to connect to the power supply unit, to the rear wall of the storage chamber and installs it along the end of the cover plate 13 near the rear wall of the storage chamber. On the one hand, this facilitates the connection of the third wire 92 to the power supply unit; on the other hand, the second slot 62 conceals the third wire 92 and avoids the third wire from being easily connected to the power supply unit. Interference between the wire 92 and the stored items causes the third wire 92 to be damaged when the stored items are retrieved, thus ensuring that the humidifier 22 can work effectively. Furthermore, protecting the third wire 92 reduces the impact of temperature and humidity within the accommodating cavity 12a defined by the drawer body 11 on the lifespan of the third wire 92, thereby improving product safety. In addition, the second slot 62, in conjunction with the wiring groove 8, is set at an angle to the extension trend of the second slot 62 and the trend of the wiring groove 8, causing the guide path to change direction, which can effectively prevent the third wire 92 from falling off and improve the stability of the third wire 92.

[0078] In some embodiments of this application, the second slot 62 is located on the side of the wiring trough 8 near the rear wall of the storage chamber, and the angle between the extending trend of the second slot 62 and the extending trend of the wiring trough 8 is denoted as ∠A, where ∠A ≠ 0°. In the above technical solution, the third wire 92, after exiting from the wiring clip, is redirected and installed in the second slot 62, which effectively prevents the third wire 92 from falling off and improves the stability of the third wire 92's fixation.

[0079] In some embodiments of this application, the power supply unit is connected to the power supply of the refrigerator 100; one end of the third wire 92 that passes through the second slot 62 is connected to the power supply unit.

[0080] The above technical solution places the power supply unit connected to the power supply of the refrigerator 100 on the rear wall of the storage compartment, and connects it to the humidifier 22 through the third wire 92, so that the humidifier 22 can be powered by the power supply of the refrigerator 100 without the need for an additional power supply.

[0081] Please refer to some embodiments of this application. Figure 15 The second slot 62 includes a first slot wall 621, which is located on the side of the cover plate 13 near the drawer body 11; the second slot 62 includes a second slot wall 622, which is connected to the end of the first slot wall 621 near the rear wall of the storage compartment; the second slot 62 includes a third slot wall 623, which is connected to the second slot wall 622 and is disposed opposite to the first slot wall 621; the second slot 62 includes a fourth slot wall 624, which is connected to the end of the first slot wall 621 away from the rear wall of the storage compartment; there is an installation gap 620 between the fourth slot wall 624 and the third slot wall 623.

[0082] In the above technical solution, the second slot 62 is used to install the third wire 92. The installation gap 620 is located on the lower side, so that the third wire 92 is installed in the second slot 62 from bottom to top, avoiding the space restriction of the cover plate 13 and facilitating the installation of the third wire 92.

[0083] In some embodiments of this application, when the drawer body 11 is installed under the cover plate 13, the rear wall of the drawer body 11 cooperates with the fourth groove wall 624.

[0084] In the above technical solution, the fourth groove wall 624 is connected to the end of the first groove wall 621 away from the rear wall of the storage chamber. It extends from top to bottom and can cooperate with the rear wall of the drawer body 11 when it is closed. This prevents the cold air blown out from one side of the rear wall of the storage chamber from directly entering the receiving cavity 12a defined by the drawer body 11, effectively preventing secondary air from directly entering the receiving cavity 12a and blowing on the food, causing it to dry out and wilt. Instead, the cold air blown out from one side of the rear wall of the storage chamber carries cold energy and slowly enters the receiving cavity 12a defined by the drawer body 11 through the gap between the side wall of the drawer body 11 and the cover plate 13. The speed at which the cold energy enters the receiving cavity 12a is even smaller, effectively preventing the food from drying out.
