Description

Technical Field

[0001] The present application relates to the technical field of refrigerators, and in particular, to a refrigerator. Background Art

[0002] Currently, food is typically thawed naturally, which involves placing frozen food at room temperature and letting the surrounding temperature thaw it. However, this method is slow and incomplete. Because food is exposed to air, it is susceptible to bacterial contamination, leading to spoilage.

[0003] To improve thawing speed and quality, various thawing methods have emerged in the prior art, including electric heating, hot water, running water, air thawing, and refrigeration. However, these methods all have drawbacks and negative consequences, such as uneven heating leading to localized ripening and reduced taste, water immersion leading to juice loss and microbial contamination, and long thawing times resulting in a poor user experience.

[0004] Furthermore, existing technologies fail to fully recognize the importance of refrigerator doors. Beyond adding traditional sealing strips, the door structure has not been specifically modified to meet the specific functional requirements of the refrigerator. The refrigerator door is one of the main components of a refrigerator, and a good door body must possess a certain strength and good thermal insulation performance. Traditional wired glass typically uses a two-layer sandwich structure. While it has certain fire and shatter resistance properties, it is relatively heavy, adding to the burden of the refrigerator door. Furthermore, the back glass layer of traditional wired glass not only increases the overall weight but also increases the manufacturing cost. Summary of the Invention

[0044] In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and are not an exhaustive list of all the embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless they conflict.

[0045] The present application embodiment provides a refrigerator. Figure 1 and Figure 2 The refrigerator comprises a door 4, a freezer compartment 2, a refrigerator compartment 1, and an air duct. An evaporator 13 is located within the duct. The refrigerator compartment 1 is divided into a refrigerated area 11 and a functional area 12. The refrigerated area 11 is used to refrigerate items such as food and beverages. The functional area 12 has at least a defrosting function and a micro-freezing function. Food in the functional area 12 can be stored in a micro-freezing state or defrosted. The micro-freezing function uses precise temperature control (approximately -3°C to 0°C) to slightly freeze the surface of ingredients such as meat and fish, while keeping the interior soft. This allows for short-term storage (approximately one week) without thawing, preserving the freshness and tenderness. Compared to freezing (-18°C), this reduces cell damage and extends the shelf life compared to refrigeration. This is suitable for frequently used food, offering a compromise between freshness and freezing. The evaporator 13 connects to the refrigerated area 11 and the functional area 12 via the air duct, providing cooling for both areas.

[0046] Specifically, functional area 12 is equipped with fans 14, including a first fan 141. First fan 141 is used for defrosting. Its primary function is to blow air directly onto the frozen food placed in functional area 12, accelerating the flow of refrigerated air within functional area 12 and thawing the frozen food through high-speed wind pressure. This high-speed airflow quickly transfers heat from the refrigerator to the surface of the food and removes any cold air from the surface, significantly shortening the thawing time. The fan's circulating airflow reduces thawing dead zones, preventing localized overheating or unthawed areas. This is particularly suitable for large items, such as whole meats. Compared to microwave thawing, it provides more uniform thawing, avoiding edge-cooking issues.

[0047] Please refer to Figure 2-5The refrigerator also includes a refrigeration air duct, in which an evaporator 13 is installed. The evaporator 13 is spaced apart from the refrigeration zone 11, forming a gap between the evaporator 13 and the refrigeration compartment 1. The evaporator 13 is at least partially located within the gap. When the evaporator 13 is in operation, it generates cooling, forming cold air within the gap. A second fan 142 is located within the gap. The second fan 142 is used for cooling. The air blown by the second fan 142 forms an airflow, which brings the cold air within the gap into the refrigeration compartment 1, thereby cooling the refrigeration compartment 1. The two ends of the gap respectively connect the refrigeration zone 11 and the functional zone 12. One side of the evaporator 13 is a supply air path. The second fan 142 delivers the cold air within the gap into the refrigeration compartment 1 through the supply air path. The other side of the evaporator 13 is a return air vent 18, which is connected to both the refrigeration zone 11 and the functional zone 12.

[0048] The second fan 142 is arranged on the side of the evaporator 13 away from the return air port 18. The air supply path includes a first air path 131 and a second air path 132. The first air path 131 is connected to the refrigerated area 11, and the second air path 132 is connected to the functional area 12. A portion of the cold air blown out from the gap enters the refrigerated area 11 to cool the refrigerator and provide a low-temperature environment for the frozen food normally stored in the refrigerator. The first air path 131 is formed in the refrigerated area 11. The circulating air in the refrigerated area 11 returns to the evaporator 13 from the return air port 18, repeating the heat exchange. This cycle continuously provides a low-temperature environment for the refrigerated area 11. Another portion of the cold air blown out from the gap enters the functional area 12, forming the second air path 132 in the functional area 12. The air exchanges heat with the food to be thawed in the functional area 12 and is then discharged. The air discharged from the functional area 12 returns to the evaporator 13 through the return air port 18, exchanges heat with the evaporator 13 again, and the cycle continues.

[0049] The advantage of this refrigerator over the prior art is that, since the first fan 141 continuously blows air on the food to be thawed, this process will take away a lot of moisture, causing the food to lose moisture and affecting the taste. To solve this problem, the refrigerator of the present invention relies on the work of the evaporator 13 itself to humidify the food to be thawed, humidifying the surface of the food while thawing, providing moisture, and preventing the food from losing moisture. In addition, the refrigerator has a simple structure and can achieve the moisturizing function of the food without the need for additional devices. Specifically, when the refrigerator functional area 12 is in a slightly frozen state, the evaporator 13 is in a normal working state and continues to cool. During this process, its surface temperature is lower than the dew point temperature of the air, causing the water vapor in the air flowing through it to condense into liquid water when it is cold, and quickly freeze into frost below 0°C. The frost layer gradually thickens and accumulates on the surface of the evaporator 13. When the refrigerator functional area 12 is in the defrosting state, after the defrosting starts, the evaporator 13 is first controlled to stop. For example, the evaporation of the refrigerant in the evaporator 13 can be stopped by regulating the solenoid valve or other means. Then, the second fan 142 is used to bring the high-temperature air in the refrigerated compartment 1 to the evaporator 13. At this time, the frost on the surface of the evaporator 13 begins to melt, and the air humidity increases rapidly. The second fan 142 then plays a humidifying role, and the moist air in the evaporator 13 is sent into the refrigerated compartment 1 by means of the wind flow to humidify the food to be thawed. In this way, the humidity inside the refrigerated compartment 1 can be increased to prevent moisture loss in the food.

[0050] In one embodiment, when the surface temperature of the evaporator 13 reaches between 0-8° C., the relative humidity in the refrigerated compartment 1 can be increased to above 90%.

[0051] Therefore, the humidity in the thawing area can be stabilized by relying only on the evaporator 13 and other related components of the refrigerator itself, so that the food to be thawed can continue to maintain humidity during the thawing process, avoiding water loss and affecting the taste.

[0052] Taking into account that the refrigerator in the embodiment of the present application is affected by the external environment, which will increase the difficulty of controlling and implementing the functional effects of the refrigerator's refrigeration compartment, especially increasing the difficulty of controlling and implementing the micro-freezing and thawing programs in the functional area, in the embodiment of the present application, an improved design is also proposed for the door body of the refrigerator, thereby providing a better enclosed space for the refrigerator's refrigeration compartment 1, preventing the cold air inside the refrigeration compartment 1 from leaking out, and reducing the heat exchange between the outside of the refrigerator and the refrigeration compartment 1, thereby ensuring the refrigeration effect inside the refrigeration compartment 1; at the same time, reducing the impact of the outside world on the micro-freezing, thawing and other programs in the functional area of ​​the refrigeration compartment; in addition, the better enclosed space can also prevent the leakage of internal moisture, which helps to maintain the humidity control inside the refrigeration compartment 1.

[0053] Specifically, see Figure 2 、 Figure 6 and Figure 7The refrigerator provided in the present application includes a refrigeration compartment 1, a refrigeration air duct and a refrigerator door; wherein, the refrigerator door has a door body 4, the door body 4 is used to close the refrigeration compartment 1, the door body 4 includes a door panel, and the door panel is sequentially provided with a three-dimensional embossed layer 410, a glass layer 420, a first adhesive layer 430, a wire layer 440, a second adhesive layer 450 and a back protective layer 460 from the outside to the inside; the first adhesive layer 430 is used to bond the glass layer 420 and the wire layer 440, and the back protective layer 460 is used to protect the wire layer 440, and the back protective layer 460 is made of PET material.

[0054] The embossed layer 410, located at the outermost layer along the thickness of the door panel, provides special tactile or visual effects, such as texture or pattern. The glass layer 420 provides transparency and a modern feel, while also increasing the overall strength and durability of the door. The first adhesive layer 430 securely bonds the glass layer 420 to the wire layer 440. The wire layer 440, which includes a metal mesh or other reinforcing material, enhances the door's safety and explosion-proof properties and also serves as an electromagnetic shield. The second adhesive layer 450 connects the wire layer 440 to the back protective layer 460, ensuring a tight bond between the layers. The back protective layer 460 protects the inner wire layer 440 and is made of PET (polyethylene terephthalate), a thermoplastic polymer with excellent mechanical properties and chemical stability, commonly used in the manufacture of films and fibers.

[0055] The 3D embossed layer 410 provides an additional design element, making the product more attractive. It also offers a certain anti-slip effect, making it easier for users to grip the door when opening it. Specifically, the 3D embossed layer 410 is formed on the outer surface of the glass layer 420 using a UMI embossing process to create a unique tactile or visual effect, such as a texture or pattern. The glass layer 420 is typically tempered glass, such as soda-lime silicate glass or tempered float glass. The 2-3 mm thick tempered glass layer 420 enhances the overall strength and durability of the door.

[0056] Specifically, the first adhesive layer 430 and the second adhesive layer 450 are made of the same material to ensure strong and consistent bonding between the glass layer 420 and the wire layer 440, as well as between the wire layer 440 and the back protective layer 460. In one embodiment, both the first adhesive layer 430 and the second adhesive layer 450 are made of PVB, a thermoplastic resin commonly used in the manufacture of safety glass interlayers due to its excellent transparency, light resistance, and adhesion to inorganic glass. Using PVB as an adhesive layer can enhance the overall structural strength and safety of the refrigerator door, particularly reducing the risk of breakage during impact, and also provide a certain degree of sound insulation. In another embodiment, both the first adhesive layer 430 and the second adhesive layer 450 are made of EVA film, which has excellent flexibility, transparency, and adhesion. Compared to PVB, EVA may offer a cost advantage, and the choice of adhesive layer can be determined based on the needs.

[0057] In an optional embodiment, the wire layer 440 is woven from metal wire or colored nylon wire; the metal wire can enhance the safety performance of the door body and provide a certain electromagnetic shielding effect, such as stainless steel wire; in another embodiment, considering aesthetics and personalized needs, the wire layer 440 can be woven from colored nylon wire to provide a certain degree of reinforcement, making the appearance more diverse and meeting the aesthetic preferences of different users.

[0058] Based on the aforementioned embodiments, the back protective layer 460 has a thickness of 0.05mm to 2mm. Made of PET, its primary function is to protect the inner wire layer 440 from scratches and abrasion during daily use. Its high light transmittance and light weight effectively reduce overall weight and manufacturing costs. Even at its thinnest thickness (0.05mm), the back protective layer 460 still provides the necessary protection for the wire layer 440, preventing damage from direct contact.

[0059] In addition to providing a better enclosed space for the refrigerator's cold storage compartment as mentioned above, effectively ensuring and improving the refrigerator's refrigeration, thawing and moisturizing effects, the newly designed door body of the refrigerator in the embodiment of the present application can also reduce the overall weight, which is conducive to the lightweight design of the refrigerator door and reduces the burden on the refrigerator door; at the same time, it reduces manufacturing costs, adds an aesthetic effect to the refrigerator door through the three-dimensional embossed layer, improves the product's visual appeal, and retains the fireproof and shatterproof properties of the wired glass to ensure the safety performance of the refrigerator.

[0075] 5) Place the assembled multilayer structure in a heated press and cure it at a temperature of 120°C-150°C and a pressure of 0.5MPa-1MPa for 2 hours.

[0076] Please continue reading Figure 8-10 In some embodiments, the refrigerator further includes a partition 20 , which is disposed in the refrigerating compartment 1 to construct a refrigerating area 11 and a functional area 12 that are separated from each other in the refrigerating compartment 1 .

[0077] In one embodiment, multiple partitions 20 may be provided, and the multiple partitions 20 collectively enclose a functional area 12 in the refrigerated compartment 1, and the remaining area in the refrigerated compartment 1 is the refrigerated area 11. The functional area 12 can be used to defrost and / or store food 3, and the refrigerated area 11 can be used to refrigerate and store food 3.

[0078] In one embodiment, the partition 20 includes an insulating layer. Because the partition 20 includes an insulating layer, heat exchange between the interior of the functional area 12 enclosed by the partition 20 and the environment outside the functional area 12 is less likely to occur. This allows the functional area 12 to defrost the food 3 placed therein without affecting the environment outside the functional area 12, such as the refrigeration and preservation of the food 3 in the refrigerated area 11.

[0079] See also Figure 8-10 In some embodiments, the refrigerator further includes a partition plate 19, which is detachably mounted on the functional area 12 to selectively divide the functional area 12 into a plurality of sub-functional areas.

[0080] In one embodiment, the partition plate 19 can be single, and the single partition plate 19 is arranged in the functional area 12, dividing the functional area 12 into two sub-functional areas. The first fan 141 is installed in one of the two sub-functional areas. The functional area 12 can be used to defrost the food 3. The other of the two sub-functional areas is not installed with the first fan 141 and can be used to slightly freeze the food 3 without defrosting it.

[0081] It can be understood that by dividing the larger functional area 12 into two smaller sub-functional areas and placing the first fan 141 in one of the sub-functional areas, the food 3 placed in the sub-functional area can be closer to the first fan 141, thereby improving the thawing effect. In this way, by dividing the functional area 12 into multiple sub-functional areas through the partition plate 19, the internal space of the functional area 12 can be fully utilized, and the functional areas 12 can have different functions while improving the thawing effect.

[0082] In one embodiment, when there is a single partition plate 19, the single partition plate 19 can be horizontally arranged in the functional area 12 to separate the functional area 12 into two upper and lower sub-functional areas;

[0083] In one embodiment, when there is a single partition plate 19, the single partition plate 19 can be vertically arranged in the functional area 12 to separate the functional area 12 into two left and right sub-functional areas.

[0084] In some embodiments, the functional area 12 includes a first functional area 121 and a second functional area 122, and the second air passage 132 is sequentially connected to the first functional area 121 and the second functional area 122. The second air passage 132 is connected to the first functional area 121, and the first functional area 121 is connected to the second functional area 122. The air blown out of the second air passage 132 enters the first functional area 121, undergoes heat exchange, and then enters the second functional area 122 from the first functional area 121.

[0085] Specifically, the first functional zone 121 is the thawing zone, and the second functional zone 122 is the partial freezing zone. The thawing zone is used to thaw frozen food, while the partial freezing zone is used to keep frozen food partially frozen. The partial freezing function (also known as "partial freezing preservation" or "soft freezing") is a preservation technology between refrigeration (0-4°C) and freezing (below -18°C). Its core principle is to precisely control the temperature to form a very thin layer of ice crystals on the surface of the food, while maintaining a partial freezing state within, preventing complete freezing. Compared to traditional refrigeration, the partial freezing function is more effective in inhibiting bacterial growth. Compared to traditional freezing, it reduces cell rupture, preserving the texture and nutrients of the food. Regarding thawing, the partial freezing function avoids the hardening of food caused by traditional freezing, allowing for immediate use. Furthermore, partial freezing consumes less energy than deep freezing, maintaining a temperature between -3°C and -7°C.

[0086] On the one hand, this design does not require an additional humidifying device, which can solve the problem of how to maintain the humidity of food during thawing and simplify the refrigerator structure; on the other hand, it is also beneficial to the defrosting of the evaporator 13, killing two birds with one stone.

[0087] In one embodiment, the first functional area 121 has a first wall 1211 with a through hole, and the second functional area 122 is connected to the first functional area 121 through the through hole. As a result, the airflow in the first functional area 121 can enter the second functional area 122 through the through hole, achieving air circulation between the two areas.

[0088] Specifically, the first fan 141 defrosts the food in the functional zone 12 by blowing air, primarily targeting the food in the first functional zone 121. During thawing, the first functional zone 121 is in a thawing state, while the second functional zone 122 is in a partially frozen state. During this process, a high-speed airflow is formed in the first functional zone 121, continuously removing cold air from the surface of the food. The cold air then flows out of the first functional zone 121 and into the second functional zone 122 through the through-holes, thereby maintaining the partially frozen state of the food in the second functional zone 122. The high-speed airflow first exchanges heat with the food to be thawed in the first functional zone 121, then enters the second functional zone 122 through the through-holes. After exchanging heat with the partially frozen food in the second functional zone 122, it exits the functional zone 12 and returns to the return air outlet 18.

[0089] In one embodiment, the second functional area 122 has a lower wall surface, and a functional area exhaust port 123 is opened on the lower wall surface. The airflow in the functional area 12 is discharged from the functional area 12 through the functional area exhaust port 123 and enters the return air port 18 for return air.

[0090] In one embodiment, the functional zone exhaust vents 123 are located on the side of the lower wall away from the through-hole. This arrangement has the advantage that when airflow from the first functional zone 121 enters the second functional zone 122 through the through-hole, it flows through the food and is discharged through the functional zone exhaust vents 123. Since the air flowing from the through-hole into the second functional zone 122 cannot completely exchange heat within the first functional zone 121, it still retains some cooling capacity. Therefore, by arranging the through-hole and the functional zone exhaust vents 123 on opposite sides, the airflow can pass over the food surface as much as possible, increasing the contact area with the food, maintaining a low temperature environment in the second functional zone 122, and improving cooling efficiency.

[0091] In one embodiment, the first functional area 121 and the second functional area 122 are arranged vertically spaced apart, the first functional area 121 has side walls and a bottom wall, and the first wall surface 1211 is the side wall of the first functional area 121. As a result, the airflow in the first functional area 121 is more easily discharged from the through hole to the second functional area 122.

[0092] In one embodiment, the first functional area 121 has a second wall 1212. Specifically, the second wall 1212 is the sidewall of the first functional area 121 away from the through-hole. The second wall 1212 can be configured as an inclined surface, and the angle between the second wall 1212 and the bottom wall of the first functional area 121 is an acute angle. The first fan 141 can be positioned above the side near the second wall 1212. As a result, the wind blown by the first fan 141 forms a wind flow. When passing through the second wall 1212, the second wall 1212 can act as a wind guide, facilitating the flow of wind through the food to be thawed. Furthermore, the inclined second wall 1212 forms an acute angle with the bottom wall of the first functional area 121. When the wind flows through the second wall 1212 to the bottom wall, the backflow force is smaller than that generated by a right angle, thereby increasing the wind flow rate and, therefore, the thawing efficiency.

[0093] In one embodiment, the bottom wall of the first functional area 121 is used to place food to be thawed, and the bottom wall can be provided with a groove 2211, and the groove 2211 extends along the direction of the wind flow, for example Figure 12The grooves 2211 extend in a longitudinal direction, and are spaced perpendicular to the direction of airflow. Specifically, the grooves 2211 are located below the food to be thawed, forming multiple channels beneath the food, thereby partially hollowing out the food. As a result, when airflow passes over the food, some of the airflow can flow through the bottom of the food, thawing the bottom of the food, preventing uneven thawing and avoiding partial thawing.

[0094] In one embodiment, the side walls of the first functional area 121 (i.e., the thawing area) are made of plastic, while the bottom wall is made of metal. The advantage of using plastic for the side walls is that plastic has low thermal conductivity, which reduces heat exchange between the side walls and the outside world, preventing condensation from forming on the inner walls of the first functional area 121. It also reduces overall weight and allows for smoother pushing and pulling. The advantage of using metal for the bottom wall is that metal has strong support, can support heavier food 3 (such as frozen meat), prevents plastic from being deformed under long-term pressure, and a metal (such as aluminum alloy) bottom wall accelerates cold transfer, ensuring even thawing of the food 3 at the bottom. It also facilitates the transfer of cold from the first functional area 121 to the second functional area 122.

[0095] In some embodiments, the refrigerator further includes a first drawer 21 and a second drawer 22, each open at the top. The first drawer 21 and the second drawer 22 are slidably mounted in the functional area 12, and the first drawer 21 and the second drawer 22 are vertically spaced apart. The refrigerator further includes a drawer cover 23, which is disposed at one end of the second drawer 22 in the front-to-back direction. The projected area of ​​the drawer cover 23 in the front-to-back direction is greater than the sum of the projected areas of the first drawer 21 and the second drawer 22 in the front-to-back direction.

[0096] It will be appreciated that the first drawer 21 and the second drawer 22 can be used to hold ingredients 3. The first drawer 21 and the second drawer 22 are slidably mounted in the functional area 12. A user can push and pull the drawer cover 23, causing the first drawer 21 and the second drawer 22 to slide, allowing the user to access and place ingredients 3. This drawer structure facilitates the user's access to and placement of ingredients 3. Furthermore, because the first drawer 21 and the second drawer 22 are arranged vertically spaced apart, they form two independent storage spaces. Therefore, different ingredients 3 can be stored separately in the first drawer 21 and the second drawer 22, facilitating isolated storage of the ingredients 3.

[0097] The drawer cover 23 is arranged at one end of the second drawer 22 along the front-to-back direction. The projected area of ​​the drawer cover 23 in the front-to-back direction is larger than the sum of the projected areas of the first drawer 21 and the second drawer 22 in the front-to-back direction. It not only has a certain shielding effect on the food 3 inside the drawer, improves the overall aesthetics of the refrigerator, but also makes it convenient for users to operate the drawer.

[0098] In some embodiments, the functional area 12 may also be provided with a sealing strip (not shown in the figure), which is installed at the edge of the functional area 12 and is distributed in a circumferential shape. When the first drawer 21 and the second drawer 22 are completely contained in the functional area 12, the drawer cover 23 close to the side of the functional area 12 will tightly stop the sealing strip, which can improve the sealing effect of the functional area 12 and prevent the external ambient temperature from affecting the freshness of the food 3 in the functional area 12. The sealing strip is generally made of a rubber material with good elasticity and low-temperature resistance. It can still remain soft and elastic in a low-temperature environment, ensuring the sealing of the functional area 12, thereby maintaining a stable low-temperature environment in the functional area 12. In specific implementation, the drawer cover 23 can be made of a layer structure with the same structural form as the door body 4 in the embodiment of the present application, further maintaining a stable low-temperature environment in the functional area 12.

[0099] In one embodiment, the sealing structure of the refrigerator includes a fully sealed structure and a semi-sealed structure. The fully sealed structure is provided with a sealing strip. When the drawer is closed, the drawer cover 23 close to the functional area 12 will tightly stop the sealing strip, strictly isolating the functional area 12 from the other compartments of the refrigerator. The advantage is that it is conducive to precise temperature control, isolates external cold and heat interference, maintains a stable thawing temperature (such as 0~4℃), and is suitable for temperature-sensitive food 3. The semi-sealed structure is partially closed (such as without a sealing strip design). When the drawer is closed, it relies only on the sealing ability of the drawer cover 23. At this time, there is limited air exchange between the drawer and other areas of the refrigerator. The advantage is that it has a simple structure, is easy to push and pull, does not need to be deliberately closed tightly, is commonly used in popular refrigerators, and the sealing is less affected by frequent opening and closing.

[0100] In some of these examples, see Figure 11-12 The side wall of the functional area 12 is provided with a first track 211 extending in the horizontal direction, the upper edge of the second drawer 22 is provided with a second track 221 extending in the horizontal direction, and the first drawer 21 has a first sliding portion 212 matched with the first track 211 and a second sliding portion 222 matched with the second track 221. Figure 11 and Figure 12 As shown, the side wall of the functional area 12 is provided with a horizontal direction (such as Figure 12 The first track 211 extends in the front-to-back direction (as shown in FIG. Figure 11 The left and right directions shown in FIG. 1 protrude from the side wall of the functional area 12.

[0101] One of the embodiments, such as the present application Figure 11 As shown, there are two first rails 211, which are located on both sides of the first drawer 21 in the left and right directions. The first rails 211 can be installed on the side wall of the functional area 12 or can be integrally formed with the side wall of the functional area 12. Figure 12As shown, the upper edge of the second drawer 22 is provided with a second rail 221 extending in the horizontal direction. There are two second rails 221, which are respectively arranged on the left and right side edges of the second drawer 22. The second rails 221 can be integrally formed with the second drawer 22, or can be installed on the second drawer 22 by fasteners.

[0102] One of the embodiments, such as the present application Figure 11 and Figure 12 As shown, the first drawer 21 is provided with a first sliding portion 212 and a second sliding portion 222 at both ends along the front-back direction, wherein the first sliding portion 212 and the second sliding portion 222 are arranged in the height direction (as shown in FIG. Figure 12 The first drawer 21 is provided with two first sliding parts 212, one on each side of the first drawer 21 along the width direction, and the second drawer 21 is provided with two second sliding parts 222, one on each side of the first drawer 21 along the width direction. The two first sliding parts 212 are respectively engaged with the two first rails 211, and the two second sliding parts 222 are respectively engaged with the two second rails 221.

[0103] It can be understood that since the first track 211 is Figure 11 The first drawer 21 protrudes from the side wall of the functional area 12 (in the left and right directions shown), so the first drawer 21 can be overlapped on the first rail 211 via the first sliding portion 212, facilitating the installation and removal of the first drawer 21 and subsequent maintenance. For example, when it is necessary to place a larger food material 3 in the functional area 12, the first drawer 21 can be removed. At this time, the second drawer 22 forms a larger space, and the overall height of the space is increased to accommodate the larger food material 3. When the larger food material 3 needs to be thawed, since the larger food material 3 can be close to the output end of the thawing device, a better thawing effect can be achieved. When it is necessary to thaw smaller food material 3, the smaller food material 3 can be directly placed in a drawer close to the thawing device, so that the smaller food material 3 can receive the heat, airflow, etc. transmitted by the thawing device at a closer distance, and can be thawed better and faster.

[0104] In one embodiment, the first sliding portion 212 may be in sliding engagement or rolling engagement with the first track 211 , and the second sliding portion 222 may be in sliding engagement or rolling engagement with the second track 221 .

[0105] In one embodiment, the first sliding portion 212 slides with the first rail 211 and the second sliding portion 222 slides with the second rail 221. At this time, the first sliding portion 212 and the second sliding portion 222 can be integrally formed with the first drawer 21, which can reduce the device structure, simplify the production process, and facilitate installation and maintenance.

[0106] In one embodiment, the first sliding portion 212 is in rolling engagement with the first rail 211, and the second sliding portion 222 is in rolling engagement with the second rail 221. Since the rolling friction of the rolling engagement is less than the sliding friction of the sliding engagement, the first drawer 21 can be pushed and pulled more smoothly, making it easier for users to operate.

[0107] In one embodiment, the first sliding portion 212 is in sliding engagement with the first rail 211 , and the second sliding portion 222 is in rolling engagement with the second rail 221 , or the first sliding portion 212 is in rolling engagement with the first rail 211 , and the second sliding portion 222 is in sliding engagement with the second rail 221 .

[0108] In one embodiment, the bottom wall of the functional area 12 may be provided with a third track (not shown in the figure), and the bottom wall of the second drawer 22 may also be provided with a third sliding portion (not shown in the figure) that cooperates with the third track.

[0109] One of the embodiments, refer to this application Figure 12 As shown, the second rail 221 is provided with two downwardly recessed grooves 2211 spaced apart along the front-to-back direction, and the grooves 2211 are adapted to the shape of the second sliding portion 222 .

[0110] It is understood that when the second sliding portion 222 falls into the groove 2211, the sliding resistance increases, thereby limiting the relative sliding of the second sliding portion 222 and the second track 221. For example, when the second sliding portion 222 falls into the groove 2211, when the second drawer 22 is driven to slide by pushing and pulling the drawer cover 23, the second sliding portion 222 of the first drawer 21 falls into the groove 2211 of the second track 221 on the second drawer 22, thereby limiting the displacement of the first drawer 21 relative to the second drawer 22. In this way, the first drawer 21 and the second drawer 22 can be pushed and pulled synchronously.

[0111] In one embodiment, functional area 12 includes a double-layer drawer 120 or a double-layer drawer structure. The first functional area 121 is an upper drawer for thawing frozen foods, while the second functional area 122 is a lower drawer for storing partially frozen foods that do not require thawing. The upper drawer is removably attached to the lower drawer. When the upper drawer is attached, the upper layer serves as the thawing area, while the lower layer serves as the partially frozen area. This clear division of labor allows the refrigerator to perform both thawing and partially frozen functions simultaneously. When the upper drawer is removed, the lower drawer functions as the thawing area, suitable for thawing larger foods.

[0112] In some embodiments, the refrigerator further includes an air duct assembly, a first air duct 131 and a second air duct 132 are formed in the air duct assembly, the refrigerated compartment 1 and the evaporator 13 are spaced apart in the horizontal direction, and the air duct assembly is located between the evaporator 13 and the refrigerated compartment 1.

[0113] Specifically, the air duct assembly is a specific structure of a gap, and the air duct assembly is connected to the refrigeration area 11, the functional area 12, and the return air outlet 18. The evaporator 13 and the refrigeration compartment 1 are respectively arranged on both sides of the air duct assembly. The evaporator 13 is at least partially located in the air duct assembly. When the evaporator 13 is working normally, it will have a cooling effect in the air duct assembly. The second fan 142 blows part of the cold air in the air duct assembly into the refrigeration area 11. The refrigeration area 11 is provided with a refrigeration area air supply port 135. The cold air enters the refrigeration area 11 from the refrigeration area air supply port 135, refrigerating the refrigeration area 11 of the refrigerator, providing a low-temperature environment for the frozen food normally stored in the refrigeration area 11, and forming a first air path 131 in the refrigeration area 11. The circulating air in the refrigeration area 11 returns to the evaporator from the return air outlet 18. 13, repeat the heat exchange, and the cycle continues to provide a low-temperature environment for the refrigerated area 11; another part of the cold air blown out of the air duct assembly enters the functional area 12, forming a second air path 132 in the functional area 12, and the functional area 12 is provided with a functional area air supply port 136. The air in the second air path 132 enters the functional area 12 from the functional area air supply port 136, and is discharged after exchanging heat with the to-be-thawed food in the functional area 12. The functional area 12 is also provided with a functional area exhaust port 123 for discharging the air after heat exchange. The air discharged from the functional area exhaust port 123 returns to the evaporator 13 through the return air port 18, and exchanges heat with the evaporator 13 again, and the cycle continues.

[0114] In one embodiment, the air duct assembly further includes a first damper 133 and a second damper 134. The first damper 133 is mounted on the first air passage 131, and the second damper 134 is mounted on the second air passage 132. The first damper 133 is adapted to close or open the first air passage 131, while the second damper 134 is adapted to close or open the second air passage 132. The arrangement of the first damper 133 and the second damper 134 allows the first and second air passages 131, 132 to be opened or closed independently of each other. In other words, the refrigerated area 11 and the functional area 12 can operate independently of each other.

[0115] See also Figure 13 In one embodiment, the first damper 133 and the second damper 134 can be either single dampers or double dampers. The first air passage 131 is provided with a first branch 1311 and a second branch 1312. The first damper 133 is a single damper for blocking the first branch 1311; the second damper 134 is a double damper for blocking the second branch 1312 and the second air passage 132. Similarly, the second air passage 132 can also be provided with branches.

[0116] In some embodiments, the functional area 12 has a connecting hole connecting it to the refrigeration area 11. The air inlet side of the first fan 141 is connected to the connecting hole, and the air outlet side of the first fan 141 is directed toward the functional area 12. Thus, the connecting hole connects the spaces of the refrigeration area 11 and the thawing area, and the air circulation is not limited to the functional area 12, but forms a comprehensive circulating air path throughout the entire refrigeration compartment 1.

[0117] Specifically, at this time, there are two air paths in the functional area 12. One is starting from the evaporator 13, entering the refrigerated area 11 through the first air path 131 in the air duct assembly, and then entering the functional area 12 from the connecting hole; the other is starting from the evaporator 13, directly entering the functional area 12 through the second air path 132 in the air duct assembly, and then merging with the air path entering the functional area 12 from the connecting hole, and together returning to the evaporator 13 from the return air port 18, forming an air path circulation.

[0118] The advantages of this design lie in cooling capacity recycling and energy conservation. Specifically, connecting the two zones eliminates the energy consumption of a separate thawing zone, preventing excessive heating of food 3 and the resulting microbial risks. Furthermore, it reduces compressor load, allowing the two zones to share a cooling source, reducing energy consumption from frequent system starts and stops, and avoiding wasteful overcooling. Excess cooling capacity in the thawing zone can be returned to the refrigerated zone 11, minimizing cooling losses.

[0119] In one embodiment, the functional area 12 and the refrigerated area 11 are not connected by a connecting hole. The two areas are independently designed and do not interfere with each other. Air circulation in the functional area 12 occurs only within the functional area 12, starting from the evaporator 13, passing through the second air path 132 within the air duct assembly and directly entering the functional area 12. The air then returns to the evaporator 13 through the return air vent 18, completing the air circulation. This design completely isolates the refrigerated area 11 from the thawing area and is particularly suitable for applications where food safety, energy efficiency, and functional independence are crucial. The advantages of this design include physical isolation of bacteria and odors, preventing blood, fishy odors, or potential bacteria (such as Listeria) generated by thawing fresh produce (such as meat and seafood) from being transmitted through the air or contact to the ready-to-eat food in the refrigerated area 11. Furthermore, it allows for precise temperature control and optimized thawing performance, preventing cold air interference. When the thawing area heats up rapidly, the temperature of the refrigerated area 11 will not fluctuate due to cold air backflow.

[0120] In one embodiment, the first fan 141 is rotatably installed in the functional area 12, and the first fan 141 is used for defrosting.

[0121] Specifically, the food to be thawed is placed in the functional area 12, and the first fan 141 is blowing air to thaw the food to be thawed. Due to the different volumes and placement of the food, if it is necessary to ensure that the first fan 141 can face the thawed food, the direction of the first fan 141 needs to be adjustable to ensure that the first fan 141 is always blowing air towards the food to be thawed, thereby improving the thawing efficiency.

[0122] In one embodiment, the functional area 12 has an upper wall surface, the communication hole is provided on the upper wall surface, and the first functional area 121 and the second functional area 122 are arranged vertically spaced apart. The relative positions of the first functional area 121 and the second functional area 122 can have various structures, such as left-right arrangement, front-back arrangement, and top-bottom arrangement. Preferably, the first functional area 121 and the second functional area 122 are arranged vertically spaced apart, and can be arranged in the top-bottom direction.

[0123] In some embodiments, the refrigerator also includes a door body 4, which is used to enclose the refrigeration compartment. The functional area 12 includes a front side wall close to the door body 4 and a rear side wall close to the air duct assembly. The air outlet of the second air path 132 passes through the rear side wall and is connected to the functional area 12; the first fan 141 is arranged on a side of the top wall of the functional area 12 close to the rear side wall, and the angle between the blowing direction of the first fan 141 and the horizontal direction is an acute angle.

[0124] Specifically, first wall 1211 is the front sidewall, on which a drawer cover 23 is provided. First fan 141 is disposed on the side of the top wall of functional area 12 near the rear sidewall. Second wall 1212 is the rear sidewall, and second wall 1212 is the sidewall of first functional area 121 away from the through-hole. Second wall 1212 can be configured as an inclined surface, with the angle between second wall 1212 and the bottom wall of first functional area 121 forming an acute angle. First fan 141 can be disposed above the side near second wall 1212. Because the blowing direction of first fan 141 forms an acute angle with the horizontal direction, the air blown by first fan 141 forms a wind flow. When passing through second wall 1212, second wall 1212 can act as a wind guide, facilitating the flow of air through the food to be thawed. Moreover, the inclined second wall 1212 forms an acute angle with the bottom wall of the first functional area 121. When the wind flows through the second wall 1212 to the bottom wall, the backflow wind force generated is smaller than that generated at a right angle, which facilitates increasing the wind flow rate, that is, improving the thawing efficiency.

[0125] In some embodiments, the refrigerator further comprises a sensing device and a control device. The sensor comprises at least a humidity sensor and a temperature sensor.

[0126] In one embodiment, the sensing device is arranged inside the cold storage compartment 1, and the sensing device can be a temperature sensor or an infrared sensor. When the sensing device is a temperature sensor, the evaporator 13 is provided with an evaporator temperature sensor 17 for detecting the temperature of the evaporator 13, so as to facilitate temperature control of the evaporator 13; the cold storage area 11 is provided with a cold storage area temperature sensor 15 for detecting the temperature of the cold storage area 11; the functional area 12 is provided with a functional area temperature sensor 16 for detecting the temperature of the functional area 12. Specifically, the sensing device can be arranged in the cold storage compartment 1 and located below the food to be thawed. When the sensing device is an infrared sensor, the sensing device can be arranged in the cold storage compartment 1 and located around the food to be thawed. The control device is connected to the sensing device, and the control device is connected to the refrigeration system of the refrigerator.

[0127] In one embodiment, the refrigerator further includes a humidity sensor adapted to detect the humidity within the refrigerating compartment 1, and to enable or disable the first air path 131, the second air path 132, and the first fan 141 via a controller based on the detected humidity within the refrigerating compartment 1. For example, the humidity sensor may be installed within the refrigerating compartment 1 to detect the humidity within the refrigerating compartment 1.

[0128] In one embodiment, the humidity sensor includes a first humidity sensor and a second humidity sensor. The first humidity sensor is installed in the functional area 12 and is suitable for detecting the humidity in the functional area 12; the second humidity sensor is installed in the refrigerated area 11 and is suitable for detecting the humidity in the refrigerated area 11.

[0129] As described above, the refrigerator proposed according to an embodiment of the present invention is capable of implementing a defrosting and humidification control function. Its operating principle or process is as follows: when the refrigerator's evaporator 13 is turned on and in the cooling state, a certain amount of frost will accumulate on the surface. When the evaporator 13 is turned off and the cooling stops, the second fan 142 remains on, driving the air circulation in the refrigeration duct and promoting the melting of the frost on the surface of the evaporator 13. At this time, the water content in the air increases, and the air humidity is rapidly increased. The high-humidity air is then delivered to the functional area 12 by the first fan 141, so that the food to be thawed in the functional area 12 can be thawed in a low-temperature, high-humidity environment. The residual cooling of the evaporator 13 prevents the temperature of the refrigeration area 11 from increasing significantly. Moreover, after adding a humidity sensor, high-humidity air can be accurately and regularly delivered to the functional area 12, so that the humidity in the functional area 12 fluctuates steadily at a high level. The humidity increase in functional area 12 is controlled by a humidity sensor, which is more intelligent and accurate. It ensures that the humidity in functional area 12 is maintained between 90% and 98% during the thawing process, preventing the surface of the thawed food 3 from drying out and condensation from forming in functional area 12. Furthermore, the thawing and humidification control method of the present invention not only increases the humidity in functional area 12, but also in refrigerated area 11, thereby improving the freshness of refrigerated compartment 1.
