Description

Technical Field

[0001] This application relates to the technical field of refrigerators, and specifically, to a refrigerator. Background Art

[0002] Currently, the thawing method of food ingredients is usually natural thawing, which means placing the frozen food ingredients in a room temperature environment and relying on the ambient temperature for thawing. However, this thawing method has problems such as slow thawing speed and incomplete thawing. Since the food ingredients are exposed to the air, they are prone to being contaminated by bacteria and causing spoilage.

[0003] In order to improve the thawing speed and thawing quality, many thawing methods such as electric heating thawing, hot water thawing, running water thawing, air thawing, and refrigerated thawing have emerged in the prior art. However, the above-mentioned thawing methods all have certain drawbacks and thus cause certain adverse consequences. For example, problems such as the decline in the quality and taste of local cooking due to uneven heating, the loss of juice and microbial contamination caused by water immersion, and the poor user experience caused by a long thawing time.

[0004] In addition, the importance of the refrigerator door has not been fully recognized in the prior art. Except for adding traditional sealing strips, the structure of the refrigerator door has not been specifically improved in combination with the specific functional requirements of the refrigerator. The refrigerator door is one of the main components of the refrigerator. A good refrigerator door body needs to have a certain strength and good heat preservation performance. Traditional wired glass usually adopts a double-layer glass layer sandwich structure. Although it has certain fire and anti-break properties, the overall weight is relatively heavy, increasing the burden on the refrigerator door.

[0019] In order to make the technical solutions and advantages in the embodiments of the present application clearer and more understandable, the following further describes the exemplary embodiments of the present application in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0020] The embodiments of the present application provide a refrigerator. Please refer to Figure 1 and Figure 2, the refrigerator includes a door body 4, a freezer compartment 2, a refrigerating compartment 1 and an air duct, and an evaporator 13 is arranged in the air duct. The refrigerating compartment 1 is divided into a refrigerating area 11 and a functional area 12. The refrigerating area 11 is used for refrigerating items such as food and beverages. The functional area 12 includes at least a thawing function and a semi-freezing function. The food in the functional area 12 can be stored normally in semi-freezing or thawed. The semi-freezing function precisely controls the temperature (about -3°C to 0°C), causing the surface of ingredients such as meat and fish to freeze slightly while keeping the inside soft. For short-term storage (about 1 week), no thawing is required, and the tender taste is retained. Compared with freezing (-18°C), cell damage is reduced; compared with refrigeration, the freshness preservation time is extended. It is suitable for ingredients that are frequently taken, and belongs to a compromise solution between freshness preservation and freezing. The evaporator 13 is connected to the refrigerating area 11 and the functional area 12 respectively through the air duct to provide cold air for the refrigerating area 11 and the functional area 12.

[0021] Specifically, a blower 14 is arranged in the functional area 12, including a first blower 141. The first blower 141 is used for thawing. Its main function is to blow air directly at the frozen food placed in the functional area 12 to accelerate the flow rate of the cold air in the functional area 12 and thaw the frozen food through high-speed wind pressure. The high-speed air flow can quickly transfer the heat in the refrigerator to the surface of the food and carry away the cold air on the surface of the food, significantly shortening the thawing time. The blower circulating air flow can reduce the thawing dead corners and avoid local overheating or unfrozen areas, especially suitable for large pieces of ingredients such as whole pieces of meat. It is more uniform than microwave thawing and avoids the problem of edge ripening.

[0022] Please refer to Figure 2-5 , the refrigerator also includes a refrigerating air duct. An evaporator 13 is installed in the refrigerating air duct. The evaporator 13 is arranged at an interval from the refrigerating area 11, and a gap is formed between the evaporator 13 and the refrigerating compartment 1. At least part of the evaporator 13 is arranged in the gap. When the evaporator 13 works, it refrigerates and forms cold air in the gap. A second blower 142 is arranged in the gap. The second blower 142 is used for refrigeration. The air blown by the second blower 142 forms an air flow, which brings the cold air in the gap into the refrigerating compartment 1 to refrigerate the refrigerating compartment 1. Both ends of the gap are respectively connected to the refrigerating area 11 and the functional area 12. One side of the evaporator 13 is a supply air duct, and the second blower 142 sends the cold air in the gap into the refrigerating compartment 1 through the supply air duct; the other side of the evaporator 13 is a return air port 18, and the return air port 18 is connected to both the refrigerating area 11 and the functional area 12.

[0023] The second blower 142 is disposed on the side of the evaporator 13 away from the return air outlet 18. The air supply path includes a first air path 131 and a second air path 132. The first air path 131 communicates with the refrigerating area 11, and the second air path 132 communicates with the functional area 12. A part of the cold air blown out from the gap enters the refrigerating area 11 to refrigerate the refrigerator, providing a low-temperature environment for the frozen foods normally stored in the refrigerator. The first air path 131 is formed in the refrigerating area 11. The circulating air in the refrigerating area 11 returns to the evaporator 13 from the return air outlet 18 for repeated heat exchange. In this way, the cycle continues to provide a low-temperature environment for the refrigerating area 11. Another part 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. After exchanging heat with the food to be thawed in the functional area 12, it is discharged. The air discharged from the functional area 12 returns to the evaporator 13 through the return air outlet 18 for further heat exchange with the evaporator 13. In this way, the cycle continues.

[0024] The advantages of this refrigerator compared with the prior art are as follows: Since the first blower 141 continuously blows air on the food to be thawed, a large amount of moisture will be taken away during this process, resulting in moisture loss of the food and affecting the taste. To solve this problem, the refrigerator of the present invention relies on the operation of the evaporator 13 itself to humidify the food to be thawed, humidifying the surface of the food while thawing to provide moisture and avoid moisture loss of the food. Moreover, the structure of this refrigerator is simple, and the moisturizing function of the food can be realized without adding additional devices. Specifically, when the functional area 12 of the refrigerator is in the semi-frozen working condition, the evaporator 13 is in the normal working state and continuously refrigerates. During this process, its surface temperature is lower than the dew point temperature of the air, causing the water vapor in the flowing air to condense into liquid water and quickly freeze into frost below 0°C. The frost layer gradually thickens and accumulates on the surface of the evaporator 13. When the functional area 12 of the refrigerator is in the thawing working condition, after starting to thaw, first control the evaporator 13 to stop, for example, by means of regulating the solenoid valve to stop the evaporation of the refrigerant in the evaporator 13, and then cooperate with the operation of the second blower 142 to bring the high-temperature air in the refrigerating 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 rapidly increases. The second blower 142 plays a humidifying role at this time, sending the wet air in the evaporator 13 into the refrigerating compartment 1 by means of the air flow to humidify the food to be thawed. Thus, the humidity inside the refrigerating compartment 1 can be increased, and moisture loss of the food can be avoided.

[0025] In one embodiment, when the surface temperature of the evaporator 13 reaches between 0 and 8°C, the relative humidity inside the refrigerating compartment 1 can be increased to more than 90%.

[0026] Thus, only relying on the relevant components such as the evaporator 13 of the refrigerator itself, the humidity in the thawing area can be stabilized, so that the food to be thawed can continuously maintain humidity during the thawing process, avoiding moisture loss and affecting the taste.

[0027] Considering that in the embodiments of the present application, the refrigerator is affected by the external environment, which increases the difficulty of controlling and implementing the functional effects of the refrigerator's refrigerating compartment, especially the difficulty of controlling and implementing the micro-freezing and thawing procedures in the functional area. In the embodiments of the present application, an improved design is also proposed for the door body of the refrigerator, so as to provide a better enclosed space for the refrigerating compartment 1 of the refrigerator, prevent the cold air inside the refrigerating compartment 1 from leaking out, reduce the heat exchange between the outside of the refrigerator and the refrigerating compartment 1, and ensure the refrigeration effect inside the refrigerating compartment 1; at the same time, reduce the influence of the outside world on the micro-freezing, thawing and other procedures in the functional area of the refrigerating compartment; in addition, the better enclosed space can also prevent the internal moisture from leaking out and help maintain the humidity control inside the refrigerating compartment 1.

[0028] Specifically, referring to Figure 2 、 Figure 6 and Figure 7 The refrigerator provided by the present application includes a refrigerating compartment 1, a refrigerating air duct and a refrigerator door; wherein, the refrigerator door has a door body 4, and the door body 4 is used to close the refrigerating compartment 1. The door body 4 includes a door body panel, and the door body panel is sequentially provided with a three-dimensional embossing layer 410, a glass layer 420, a first adhesive layer 430, a wire mesh layer 440, a second adhesive layer 450 and a back protective layer 460 from outside to inside; the first adhesive layer 430 is used to bond the glass layer 420 and the wire mesh layer 440, and the back protective layer 460 is used to protect the wire mesh layer 440, and the back protective layer 460 is made of PET material.

[0029] The three-dimensional embossing layer 410 is located at the outermost layer in the thickness direction of the door body panel, and it is used to provide a special tactile or visual effect, such as texture or pattern. The glass layer 420 provides transparency and a modern sense, and also increases the overall strength and durability of the door body; the first adhesive layer 430 is used to firmly bond the glass layer 420 and the wire mesh layer 440 together. The wire mesh layer 440 has a metal wire mesh or other reinforcing materials, which increases the safety and explosion-proof performance of the door body and can also be used as an electromagnetic shielding layer. The second adhesive layer 450 connects the wire mesh layer 440 and the back protective layer 460 to ensure the tight combination between the layers. The back protective layer 460 protects the internal wire mesh layer 440 and is made of PET (polyethylene terephthalate) material. PET is a thermoplastic polymer with good mechanical properties and chemical stability, and is commonly used in the manufacture of films and fibers.

[0030] The three-dimensional embossing layer 410 provides additional design elements, making the product more attractive. It has a certain anti-slip effect, which is convenient for users to hold when opening the door; specifically, the three-dimensional embossing layer 410 is formed on the outer surface of the glass layer 420 by using the UMI embossing process to provide a special tactile or visual effect, such as texture or pattern. The glass layer 420 is specifically tempered glass, such as soda-lime silicate glass or tempered float glass. The glass layer 420 is 2-3 mm thick tempered glass to increase the overall strength and durability of the door body.

[0031] Specifically, the materials of the first adhesive layer 430 and the second adhesive layer 450 are the same to ensure the bonding strength and consistency between the glass layer 420 and the wire mesh layer 440, as well as between the wire mesh 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 material. PVB is a thermoplastic resin commonly used in the manufacture of the interlayer of safety glass because it has good transparency, light resistance, and good bonding performance to inorganic glass. Using PVB as the adhesive layer can increase the overall structural strength and safety of the refrigerator door, especially reducing the risk of breakage when impacted, and also providing a certain degree of sound insulation effect. In another embodiment, both the first adhesive layer 430 and the second adhesive layer 450 are EVA film; it has excellent flexibility, transparency, and bonding performance. Compared with PVB, EVA may be more cost-effective, and the adhesive layer can be selected according to needs.

[0032] In an alternative embodiment, the wire mesh layer 440 is made of 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, etc. In another embodiment, considering aesthetics and personalized needs, the wire mesh layer 440 can be made of colored nylon wire, providing a certain degree of reinforcement and making the appearance more diverse to meet the aesthetic preferences of different users.

[0033] Based on the above embodiments, the thickness of the back protective layer 460 is 0.05 mm - 2 mm. The back protective layer 460 is made of PET material, and its main function is to protect the internal wire mesh layer 440 from scratches and abrasions during daily use; it has high light transmittance and low weight, which can effectively reduce the overall weight and manufacturing cost. Even when the back protective layer 460 is relatively thin (0.05 mm), it can provide necessary protection for the wire mesh layer 440 to avoid damage caused by direct contact.

[0034] In addition to providing a better sealed space for the refrigerating compartment of the refrigerator as mentioned above, effectively ensuring and improving the refrigeration, defrosting, and moisturizing effects of the refrigerator, the newly designed door body of the refrigerator in the embodiments of the present application can also reduce the overall weight, which is beneficial to the lightweight design of the refrigerator door and reduces the burden on the refrigerator door; at the same time, it reduces the manufacturing cost, adds an aesthetic effect to the refrigerator door through the three-dimensional embossing layer, improves the visual attractiveness of the product, and retains the fire and anti-break properties of the wired glass to ensure the safety performance of the refrigerator.

[0035] Preferred Embodiment 1: The refrigerator provided by the present application, its door body 4 includes a door body panel, and the door body panel is sequentially provided with a three-dimensional embossing layer 410, a glass layer 420, a first adhesive layer 430, a wire mesh layer 440, a second adhesive layer 450, and a back protective layer 460 from outside to inside; the glass layer 420 is made of tempered glass with a thickness of 2 mm - 3 mm; the first adhesive layer 430 is made of PVB film with a thickness of 0.1 mm - 0.3 mm; the wire mesh layer 440 is woven from colored metal wires with a wire diameter of 0.05 mm - 0.2 mm; the second adhesive layer 450 is made of PVB film with a thickness of 0.1 mm - 0.3 mm; the back protective layer 460 is made of wear-resistant and scratch-resistant plastic film with a thickness of 0.05 mm - 0.2 mm.

[0038] Preferred Embodiment 2: The door body 4 provided by the present application includes a door body panel, and the door body panel is sequentially provided with a three-dimensional embossing layer 410, a glass layer 420, a first adhesive layer 430, a wire mesh layer 440, a second adhesive layer 450, and a back protective layer 460 from outside to inside; the thickness of the tempered glass layer 420 is 2 mm - 3 mm; the first adhesive layer 430 is made of EVA film with a thickness of 0.1 mm - 0.3 mm; the wire mesh layer 440 is woven from colored metal wires with a wire diameter of 0.05 mm - 0.2 mm; the second adhesive layer 450 is made of EVA film with a thickness of 0.1 mm - 0.3 mm; the back protective layer 460 is made of wear-resistant and scratch-resistant plastic film with a thickness of 0.05 mm - 0.2 mm.

[0041] Please continue to refer to Figures 8-10 , in some embodiments, the refrigerator further includes a partition 20, and the partition 20 is disposed in the refrigerating compartment 1 to construct a separated refrigerating area 11 and a functional area 12 in the refrigerating compartment 1.

[0042] In one embodiment, a plurality of partitions 20 may be provided, and the plurality of partitions 20 jointly enclose the functional area 12 in the refrigerating compartment 1, and the remaining area in the refrigerating compartment 1 is the refrigerating area 11. Among them, the functional area 12 can be used for thawing and / or storing the food ingredients 3, and the refrigerating area 11 can refrigerate and store the food ingredients 3.

[0043] In one embodiment, the partition 20 has a sandwich layer filled with heat-insulating material. Since the partition 20 has a sandwich layer filled with heat-insulating material, the internal environment of the functional area 12 surrounded by the partition 20 is not easily thermally exchanged with the external environment of the functional area 12. Thus, when the functional area 12 thaws the food ingredients 3 placed therein, it will not affect the environment outside the functional area 12, such as not affecting the refrigerated and fresh-keeping effect of the food ingredients 3 in the refrigerating area 11.

[0044] Please refer to Figures 8-10 , in some of these embodiments, the refrigerator further includes a partition board 19, and the partition board 19 is detachably installed in the functional area 12 to selectively divide the functional area 12 into a plurality of sub-functional areas.

[0045] In one embodiment, the partition plate 19 can be single. The single partition plate 19 is disposed in the functional area 12, dividing the functional area 12 into two sub-functional areas. The first blower 141 is installed in one of the two sub-functional areas. This functional area 12 can be used to thaw the foodstuff 3, and the other of the two sub-functional areas where the first blower 141 is not installed can be used to slightly freeze the foodstuff 3 without thawing it.

[0046] It can be understood that by dividing the relatively large functional area 12 into two relatively small sub-functional areas and placing the first blower 141 in one of the sub-functional areas, the foodstuff 3 placed in this sub-functional area can be closer to the first blower 141, 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 while enabling the functional area 12 to have different functions, the thawing effect can also be improved.

[0047] In one embodiment, when the partition plate 19 is single, the single partition plate 19 can be horizontally disposed in the functional area 12, dividing the functional area 12 into upper and lower two sub-functional areas; In one embodiment, when the partition plate 19 is single, the single partition plate 19 can be vertically disposed in the functional area 12, dividing the functional area 12 into left and right two sub-functional areas.

[0048] In some embodiments, the functional area 12 includes a first functional area 121 and a second functional area 122, and the second air duct 132, the first functional area 121, and the second functional area 122 are connected in sequence. The second air duct 132 is connected to the first functional area 121, the first functional area 121 is connected to the second functional area 122, and the air blown out by the second air duct 132 enters the first functional area 121. After heat exchange, it enters the second functional area 122 from the first functional area 121.

[0049] Specifically, the first functional area 121 is a thawing functional area, and the second functional area 122 is a slightly freezing functional area. The thawing functional area is used to thaw the food to be thawed, and the slightly freezing functional area is used to keep the frozen food in a slightly frozen state. The slightly freezing function (also known as "slightly 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 an extremely thin ice crystal layer on the surface of the food, while the inside remains in a slightly frozen state to avoid complete freezing. The slightly freezing function is better than the traditional refrigeration function in inhibiting bacterial reproduction. At the same time, compared with the traditional freezing function, it can reduce cell rupture and retain the taste and nutrition of the foodstuff 3. In terms of thawing, the slightly freezing function can avoid the hardening of the foodstuff 3 caused by traditional freezing and can be taken and used at any time. In terms of energy saving and power saving, slightly freezing consumes less energy than deep freezing in maintaining -3°C to -7°C.

[0050] In this design, on the one hand, there is no need to additionally set up a humidifying device, which can solve the problem of how to maintain the humidity of food during thawing and simplify the structure of the refrigerator; on the other hand, it is also beneficial to defrost the evaporator 13, killing two birds with one stone.

[0051] In one embodiment, the first functional area 121 has a first wall surface 1211, and through holes are provided on the first wall surface 1211. The second functional area 122 is communicated with the first functional area 121 through the through holes. Thus, the air flow in the first functional area 121 can enter the second functional area 122 through the through holes, realizing the air circulation between the two areas.

[0052] Specifically, the first fan 141 blows air to thaw the food in the functional area 12, mainly for thawing the food in the first functional area 121. During thawing, the first functional area 121 is in the thawing working condition, and the second functional area 122 is in the slightly frozen working condition. During this process, a high-speed air flow will be formed in the first functional area 121. The high-speed air flow continuously takes away the cold air on the surface of the food. The cold air flows out of the first functional area 121 and enters the second functional area 122 through the through holes, which is used to keep the food that does not need to be thawed placed in the second functional area 122 in a slightly frozen state. After the high-speed air flow exchanges heat with the food to be thawed in the first functional area 121, it enters the second functional area 122 through the through holes, exchanges heat with the slightly frozen food in the second functional area 122, and then discharges from the functional area 12 and returns to the air return port 18.

[0053] In one embodiment, the second functional area 122 has a lower wall surface, and a functional area air outlet 123 is opened on the lower wall surface. The air flow in the functional area 12 is discharged from the functional area 12 through the functional area air outlet 123 and enters the air return port 18 for air return.

[0054] In one embodiment, the functional area air outlet 123 is opened on one side of the lower wall surface away from the through holes. The advantage of this setting is that when the air flow in the first functional area 121 enters the second functional area 122 from the through holes, it will flow through the food from the through holes and then be discharged from the functional area air outlet 123. Since the air blown into the second functional area 122 through the through holes cannot be completely heat-exchanged in the first functional area 121 and still has cold energy, setting the through holes and the functional area air outlet 123 on both sides respectively can make the air flow blow over the food surface as much as possible, increase the contact area with the food, maintain the low-temperature environment in the second functional area 122, and improve the cooling efficiency.

[0055] In one embodiment, the first functional area 121 and the second functional area 122 are arranged at intervals in the vertical direction. The first functional area 121 has a side wall and a bottom wall, and the first wall surface 1211 is the side wall of the first functional area 121. Thus, the air flow in the first functional area 121 is more convenient to be discharged from the through holes to the second functional area 122.

[0056] In one embodiment, the first functional area 121 has a second wall surface 1212. Specifically, the second wall surface 1212 is the side wall of the first functional area 121 on the side away from the through hole. The second wall surface 1212 can be configured as an inclined surface, and the angle between the second wall surface 1212 and the bottom wall of the first functional area 121 is an acute angle. The first fan 141 can be arranged above the side close to the second wall surface 1212. Thus, the air blown by the first fan 141 forms an air current. When passing through the second wall surface 1212, the second wall surface 1212 can play a role in guiding the air, facilitating the air current to flow through the food to be thawed. Moreover, the inclined second wall surface 1212 and the bottom wall of the first functional area 121 form an acute angle. When the air current flows through the second wall surface 1212 and reaches the bottom wall, the return air force generated relative to a right angle is smaller, facilitating the increase of the air current velocity, that is, improving the thawing efficiency.

[0057] In one embodiment, the bottom wall of the first functional area 121 is used to place the food to be thawed. The bottom wall can be provided with grooves 2211, and the grooves 2211 extend along the direction of the air current flow, for example Figure 12 extending in the front-back direction, and a plurality of grooves 2211 are arranged at intervals along the direction perpendicular to the air current flow. That is to say, the grooves 2211 are located below the food to be thawed, forming multiple channels below the food to be thawed, so that the food to be thawed is partially hollowed out. Thus, when the air current flows through the food to be thawed, part of the air current can flow through the bottom of the food to be thawed, thawing the bottom of the food to be thawed, preventing uneven thawing and avoiding local thawing.

[0058] In one embodiment, the side wall of the first functional area 121, that is, the thawing functional area, is made of plastic, and the bottom wall is made of metal. The advantage of using plastic for the side wall is that the plastic has a low thermal conductivity, reducing the heat exchange between the side wall and the outside, avoiding the formation of frost on the inner wall of the first functional area 121, and reducing the overall weight, making the push-pull smoother. The advantage of using metal for the bottom wall is that the metal has strong supporting force, can carry heavier food materials 3 (such as frozen meat blocks), avoiding the long-term compression deformation of plastic, and moreover, the metal (such as aluminum alloy) bottom wall can accelerate the cold quantity transfer, ensuring the uniform thawing of the bottom food materials 3, and also facilitating the transfer of the cold quantity of the first functional area 121 to the second functional area 122.

[0059] In some embodiments, the refrigerator further includes a first drawer 21 and a second drawer 22 that are open at the top. The first drawer 21 and the second drawer 22 are slidably installed in the functional area 12, and the first drawer 21 and the second drawer 22 are arranged at intervals in the vertical direction. The refrigerator further includes a drawer mask 23. The drawer mask 23 is arranged at one end of the second drawer 22 in the front-back direction, and the projected area of the drawer mask 23 in the front-back direction is larger than the sum of the projected areas of the first drawer 21 and the second drawer 22 in the front-back direction.

[0060] It is understandable that the first drawer 21 and the second drawer 22 can be used to carry food ingredients 3. The first drawer 21 and the second drawer 22 are slidably installed in the functional area 12. The user can push and pull the drawer face mask 23 to drive the sliding of the first drawer 21 and the second drawer 22 to achieve the taking and placing of the food ingredients 3. By setting the drawer structure, it is convenient for the user to operate the taking and placing of the food ingredients 3. And since the first drawer 21 and the second drawer 22 are arranged at intervals in the vertical direction, in this way, the first drawer 21 and the second drawer 22 form two independent storage spaces. Therefore, different food ingredients 3 can be stored in the first drawer 21 and the second drawer 22 respectively, which is convenient for the isolated storage of the food ingredients 3.

[0061] The drawer face mask 23 is arranged at one end of the second drawer 22 in the front-back direction. The projected area of the drawer face mask 23 in the front-back direction is larger than the sum of the projected areas of the first drawer 21 and the second drawer 22 in the front-back direction. It not only plays a certain role in blocking the food ingredients 3 inside the drawer and improves the overall aesthetics of the refrigerator, but also facilitates the user to operate the drawer.

[0062] In some embodiments, the functional area 12 can also be provided with a sealing strip (not shown in the figure). The sealing strip is installed at the edge position of the functional area 12 and is distributed in a surrounding shape. When the first drawer 21 and the second drawer 22 are completely accommodated in the functional area 12, the side of the drawer face mask 23 close to the functional area 12 will tightly abut against the sealing strip. In this way, the sealing effect of the functional area 12 can be improved, and the influence of the external environmental temperature on the freshness preservation effect of the food ingredients 3 in the functional area 12 can be avoided. 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 performance of the functional area 12, thereby maintaining a stable low-temperature environment in the functional area 12. Specifically, when implemented, the drawer face mask 23 can be made of a layer structure with the same structural form as the door body 4 in the embodiments of the present application, further maintaining a stable low-temperature environment in the functional area 12.

[0063] In one of the embodiments, the sealing structure of the refrigerator includes a fully sealed structure and a semi-sealed structure. The fully sealed structure is to set a sealing strip. When the drawer is closed, the side of the drawer face mask 23 close to the functional area 12 will tightly abut against the sealing strip, strictly isolating the functional area 12 from other compartments of the refrigerator. The advantage is that it is conducive to accurate temperature control, isolates external heat and cold interference, and maintains a stable thawing temperature (such as 0-4°C), which is suitable for food ingredients 3 that are sensitive to temperature. The semi-sealed structure is partially closed (such as no sealing strip design). When the drawer is closed, it only relies on the sealing ability of the drawer face mask 23. At this time, there is a limited air exchange between the drawer and other areas of the refrigerator. The advantage is that the structure is simple, the push-pull is smooth, there is no need to close it tightly deliberately, it is commonly used in popular refrigerators, and the sealing performance is less affected by frequent opening and closing.

[0064] In some of these embodiments, please refer to Figures 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 part 212 cooperating with the first track 211 and a second sliding part 222 cooperating with the second track 221. As in this application Figure 11 and Figure 12 shown, the side wall of the functional area 12 is provided with a first track 211 extending in the horizontal direction (such as the front-back direction shown in Figure 12 ), and the first track 211 protrudes from the side wall of the functional area 12 in the width direction (such as the left-right direction shown in Figure 11 ).

[0065] In one embodiment, as in this application Figure 11 shown, there are two first tracks 211, which are respectively located on both sides of the first drawer 21 in the left-right direction. The first track 211 can be installed on the side wall of the functional area 12 or integrally formed with the side wall of the functional area 12. As in Figure 12 shown, the upper edge of the second drawer 22 is provided with a second track 221 extending in the horizontal direction. There are two second tracks 221, which are respectively arranged on both side edges of the second drawer 22 in the left-right direction. Among them, the second track 221 can be integrally formed with the second drawer 22 or installed on the second drawer 22 through fasteners.

[0066] In one embodiment, as in this application Figure 11 and Figure 12 shown, the two ends of the first drawer 21 in the front-back direction are respectively provided with a first sliding part 212 and a second sliding part 222. Among them, the first sliding part 212 and the second sliding part 222 are spaced apart in the height direction (such as the up-down direction shown in Figure 12 ). There are two first sliding parts 212, which are respectively arranged on both sides of the first drawer 21 in the width direction. There are two second sliding parts 222, which are respectively arranged on both sides of the first drawer 21 in the width direction. The two first sliding parts 212 respectively cooperate with the two first tracks 211, and the two second sliding parts 222 respectively cooperate with the two second tracks 221.

[0067] It can be understood that since the first track 211 is in the width direction (such as Figure 11protrudes from the side wall of the functional area 12 in the left - right direction (as shown), so the first drawer 21 can be lapped on the first track 211 through the first sliding part 212, which is convenient for the installation, disassembly and subsequent maintenance of the first drawer 21. For example, when a relatively large - volume food ingredient 3 needs to be placed in the functional area 12, the first drawer 21 can be disassembled. At this time, the second drawer 22 forms a larger space, and the overall height of the space increases to accommodate the large - volume food ingredient 3. When the large - volume food ingredient 3 needs to be thawed, since the large - volume food ingredient 3 can be close to the output end of the thawing device, a better thawing effect can be achieved. When a small - volume food ingredient 3 needs to be thawed, the small - volume food ingredient 3 can be directly placed in the drawer close to the thawing device, so that the small - volume food ingredient 3 can receive the heat, air flow, etc. transmitted by the thawing device at a closer distance, and the thawing can be achieved better and faster.

[0068] In one embodiment, the first sliding part 212 can be in sliding or rolling cooperation with the first track 211, and the second sliding part 222 and the second track 221 can be in sliding or rolling cooperation.

[0069] In one embodiment, the first sliding part 212 is in sliding cooperation with the first track 211 and the second sliding part 222 is in sliding cooperation with the second track 221. At this time, the first sliding part 212 and the second sliding part 222 can be integrally formed with the first drawer 21. In this way, the device structure can be reduced, the production process can be simplified, and the installation and maintenance are facilitated.

[0070] In one embodiment, the first sliding part 212 is in rolling cooperation with the first track 211, and the second sliding part 222 is in rolling cooperation with the second track 221. Since the rolling friction of the rolling cooperation is less than the sliding friction of the sliding cooperation, the smoothness of the first drawer 21 during pushing and pulling can be improved, which is convenient for user operation.

[0071] In one embodiment, the first sliding part 212 is in sliding cooperation with the first track 211 and the second sliding part 222 is in rolling cooperation with the second track 221, or the first sliding part 212 is in rolling cooperation with the first track 211 and the second sliding part 222 is in sliding cooperation with the second track 221.

[0072] In one embodiment, the bottom wall of the functional area 12 can be provided with a third track (not shown in the figure), and the bottom wall of the second drawer 22 can also be provided with a third sliding part (not shown in the figure) that cooperates with the third track.

[0073] In one embodiment, referring to the present application Figure 12 As shown, the second track 221 is provided with two downward - recessed grooves 2211 at intervals in the front - rear direction, and the shape of the grooves 2211 is adapted to the shape of the second sliding part 222.

[0074] It can be understood that when the second sliding part 222 falls into the groove 2211, the relative sliding between the second sliding part 222 and the second track 221 can be restricted due to the increased sliding resistance. For example, when the second sliding part 222 falls into the groove 2211, when the drawer face mask 23 is pushed or pulled to drive the second drawer 22 to slide, since the second sliding part 222 of the first drawer 21 falls into the groove 2211 of the second track 221 on the second drawer 22, the displacement of the first drawer 21 relative to the second drawer 22 can be restricted. In this way, the first drawer 21 and the second drawer 22 can be pushed and pulled synchronously.

[0075] In one embodiment, the functional area 12 includes a double-layer drawer 120 or the functional area 12 has a double-layer drawer 120 structure. The first functional area 121 drawer is the upper drawer for thawing the food to be thawed, and the second functional area 122 drawer is the lower drawer for storing the slightly frozen food that does not need to be thawed. The upper drawer is detachably installed on the lower drawer. When the upper drawer is not removed, the upper layer is the thawing area and the lower layer is the slightly frozen area, with clear division of labor, enabling the refrigerator to perform thawing and slightly freezing functions simultaneously; when the upper drawer is removed, the lower drawer as a whole forms the thawing area, which is suitable for thawing larger foods.

[0076] In some embodiments, the refrigerator further includes an air duct assembly. The first air duct 131 and the second air duct 132 are formed in the air duct assembly. The refrigerating compartment 1 and the evaporator 13 are arranged at intervals in the horizontal direction, and the air duct assembly is located between the evaporator 13 and the refrigerating compartment 1.

[0077] Specifically, the air duct assembly has a specific structure with gaps, and the air duct assembly is in communication with the refrigerating area 11, the functional area 12, and the air return opening 18. The evaporator 13 and the refrigerating compartment 1 are respectively arranged on both sides of the air duct assembly. At least part of the evaporator 13 is located inside the air duct assembly. When the evaporator 13 is operating normally, it will produce a refrigerating effect inside the air duct assembly. The second blower 142 blows part of the cold air in the air duct assembly into the refrigerating area 11. The refrigerating area 11 is provided with a refrigerating area air supply opening 135, and the cold air enters the refrigerating area 11 from the refrigerating area air supply opening 135 to refrigerate the refrigerating area 11 of the refrigerator, providing a low-temperature environment for the frozen foods normally stored in the refrigerating area 11 and forming a first air path 131 in the refrigerating area 11. The circulating air in the refrigerating area 11 returns to the evaporator 13 from the air return opening 18 for repeated heat exchange, and so on in a cycle, continuously providing a low-temperature environment for the refrigerating area 11; another part of the cold air blown out from the air duct assembly enters the functional area 12, forming a second air path 132 in the functional area 12. The functional area 12 is provided with a functional area air supply opening 136, and the air in the second air path 132 enters the functional area 12 from the functional area air supply opening 136, exchanges heat with the food to be thawed in the functional area 12 and then is discharged. The functional area 12 is also provided with a functional area air exhaust opening 123 for exhausting the air after heat exchange. The air exhausted from the functional area air exhaust opening 123 returns to the evaporator 13 through the air return opening 18 for heat exchange with the evaporator 13 again, and so on in a cycle.

[0078] In one embodiment, the air duct assembly further includes a first air damper 133 and a second air damper 134. The first air damper 133 is installed in the first air path 131, and the second air damper 134 is installed in the second air path 132. The first air damper 133 is adapted to close or open the first air path 131, and the second air damper 134 is adapted to close or open the second air path 132. The settings of the first air damper 133 and the second air damper 134 enable the first air path 131 and the second air path 132 to be separately opened or closed without interference. That is to say, the refrigerating area 11 and the functional area 12 can work independently of each other.

[0079] Please refer to Figure 13 , in one embodiment, the first air damper 133 and the second air damper 134 can be single air dampers or double air dampers. The first air path 131 is provided with a first branch 1311 and a second branch 1312. The first air damper 133 is a single air damper for blocking the first branch 1311; the second air damper 134 is a double air damper for blocking the second branch 1312 and the second air path 132. Similarly, the second air path 132 can also be provided with branches.

[0080] In some embodiments, the functional area 12 has a connecting hole connected to the refrigerating 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 faces the functional area 12. Thus, the space of the refrigerating area 11 and the thawing area are connected through the connecting hole, and the air circulation is not limited to the inside of the functional area 12, but forms an integral circulating air circuit in the entire refrigerating compartment 1.

[0081] 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 returning to the evaporator 13 from the return air port 18 together, forming an air path circulation.

[0082] The advantages of this design are cold recycling and energy saving. Specifically, the connection between the two zones can avoid the energy consumption of the thawing zone alone, and prevent the excessive heating of the food 3, which may lead to microbial risks; at the same time, it reduces the load on the compressor, and the two zones share the cold source, which reduces the energy consumption of the system's frequent start and stop, and also avoids overcooling waste: the excess cold in the thawing zone can flow back to the refrigeration zone 11, reducing the loss of cold.

[0083] In one embodiment, the functional area 12 and the refrigerated area 11 are not provided with a connecting hole, and the two areas are independently arranged and do not interfere with each other. The air circulation of the functional area 12 is only carried out inside the functional area 12, starting from the evaporator 13, directly entering the functional area 12 through the second air path 132 in the air duct assembly, and then returning to the evaporator 13 from the return air port 18 to form an air circulation. This design completely isolates the refrigerated area 11 from the thawing area, and is particularly suitable for scenes with high requirements for food safety, energy efficiency and functional independence. The advantage of this design is that, on the one hand, it can physically isolate bacteria and odors, and the blood, fishy smell or potential bacteria (such as Listeria) generated by thawing fresh food (such as meat and seafood) cannot be transmitted to the ready-to-eat food in the refrigerated area 11 through air or contact; on the other hand, it can accurately control the temperature and optimize the thawing performance to avoid cold interference. When the thawing area heats up quickly, the temperature of the refrigerated area 11 will not fluctuate due to the refrigeration of cold air.

[0084] In one embodiment, the first fan 141 is rotatably installed in the functional area 12, and the first fan 141 is used for defrosting.

[0085] Specifically, the food to be thawed is placed in the functional area 12, and the first blower 141 blows air to thaw the food to be thawed. Due to the different volumes and placement positions of the food, if it is necessary to ensure that the first blower 141 can face the food to be thawed, the orientation of the first blower 141 needs to be adjustable, so as to ensure that the first blower 141 always blows air to the food to be thawed and improve the thawing efficiency.

[0086] In one embodiment, the functional area 12 has an upper wall surface, a communication hole is provided on the upper wall surface, and the first functional area 121 and the second functional area 122 are arranged at intervals in the vertical direction. The relative positions of the first functional area 121 and the second functional area 122 can have various structures, such as arranged left and right, front and back, up and down, etc. Preferably, the first functional area 121 and the second functional area 122 are arranged at intervals in the vertical direction, and can be arranged in the up and down direction.

[0087] In some embodiments, the refrigerator further includes a door body 4. The door body 4 is used to close the refrigerating 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 duct 132 passes through the rear side wall and communicates with the functional area 12; the first blower 141 is arranged on one side of the top wall of the functional area 12 close to the rear side wall, and the blowing direction of the first blower 141 forms an acute angle with the horizontal direction.

[0088] Specifically, the first wall surface 1211 is the front side wall, and a drawer face mask 23 is provided. The first blower 141 is arranged on one side of the top wall of the functional area 12 close to the rear side wall. The second wall surface 1212 is the rear side wall. The second wall surface 1212 is the side wall of the first functional area 121 away from the through hole. The second wall surface 1212 can be configured as an inclined surface. The angle between the second wall surface 1212 and the bottom wall of the first functional area 121 forms an acute angle. The first blower 141 can be arranged above the side close to the second wall surface 1212. Since the blowing direction of the first blower 141 forms an acute angle with the horizontal direction, the air blown out by the first blower 141 forms an air current. When passing through the second wall surface 1212, the second wall surface 1212 can play a role in guiding the air current, facilitating the air current to flow through the food to be thawed. Moreover, the inclined second wall surface 1212 forms an acute angle with the bottom wall of the first functional area 121. When the air current flows through the second wall surface 1212 and reaches the bottom wall, the backflow wind force generated relative to a right angle is smaller, which is convenient for increasing the air current velocity, that is, improving the thawing efficiency.

[0089] In some embodiments, the refrigerator further includes a sensing device and a control device. The sensors at least include a humidity sensor and a temperature sensor.

[0090] In one embodiment, the sensing device is disposed inside the refrigerating 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 to facilitate temperature control of the evaporator 13; the refrigerating area 11 is provided with a refrigerating area temperature sensor 15 for detecting the temperature of the refrigerating area 11; and 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 disposed in the refrigerating compartment 1 and below the food to be thawed. When the sensing device is an infrared sensor, the sensing device can be disposed in the refrigerating compartment 1 and 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.

[0091] In one embodiment, the refrigerator further includes a humidity sensor, and the humidity sensor is adapted to detect the humidity inside the refrigerating compartment 1 so as to turn on or off the first air duct 131, the second air duct 132, and the first blower 141 through the controller according to the detected humidity of the refrigerating compartment 1. Exemplarily, the humidity sensor can be installed inside the refrigerating compartment 1 to detect the humidity inside the refrigerating compartment 1.

[0092] 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 adapted to detect the humidity in the functional area 12; the second humidity sensor is installed in the refrigerating area 11 and is adapted to detect the humidity in the refrigerating area 11.

[0093] As described above, the refrigerator proposed according to the embodiments of the present invention can achieve the thawing and humidification control function. Its working principle or process is as follows: when the evaporator 13 of the refrigerator is turned on and in the refrigeration working state, a certain amount of frost will accumulate on its surface; when the evaporator 13 is turned off and the refrigeration stops, the second blower 142 continues to operate, driving the air flow in the refrigerating air duct to circulate, 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. Then, the high-humidity air is sent into the functional area 12 by the first blower 141, so that the food to be thawed in the functional area 12 can be thawed in a low-temperature and high-humidity environment. The residual cold of the evaporator 13 ensures that the temperature of the refrigerating area 11 does not increase significantly. Moreover, after adding a humidity sensor, the high-humidity air can be accurately sent into the functional area 12 at regular intervals, so that the humidity in the functional area 12 is stabilized within a high-level fluctuation range. Increasing the humidity in the functional area 12 is controlled by the humidity sensor, which is more intelligent and accurate, ensuring that the humidity in the functional area 12 can be maintained between 90% and 98% during the thawing process, the surface of the food ingredient 3 to be thawed will not be air-dried, and there will be no condensation in the functional area 12. In addition, through the thawing and humidification control method of the embodiments of the present invention, not only can the humidity in the functional area 12 be increased, but also the humidity in the refrigerating area 11 can be increased, thereby improving the freshness preservation effect of the refrigerating compartment 1.

[0094] Although the preferred embodiments of the present application have been described, those skilled in the art can make additional changes and modifications once they learn the basic creative concepts. Therefore, the appended claims are intended to be construed to include the preferred embodiments as well as all changes and modifications falling within the scope of the present application.

[0095] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalent technologies, the present application is also intended to include these modifications and variations.
