Detailed Implementation

[0054] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0055] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0056] In the description of this invention, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0057] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0058] The main cooling method used in refrigerators today is frost-free cooling, which utilizes air for cooling. When hot air flows through the built-in evaporator (separate from the refrigerator's inner walls), heat exchange occurs directly between the high-temperature air and the low-temperature evaporator, causing the air temperature to drop. This cooled air is then blown into the refrigerator, and through this continuous circulation, the refrigerator's temperature is lowered. Frost-free refrigerators are widely used due to their advantages, such as being frost-free and maintaining a fresh odor inside the refrigerator through air circulation.

[0059] However, because frost-free refrigerators blow cold air directly, the humidity in the freezer compartment can easily become too low. This is especially true when the cold air blows directly onto the food in the freezer, causing the food to lose moisture more quickly, particularly on the surface. This leads to severe dehydration and accelerated oxidation. For frozen meat, this can easily result in DFD (dry, coarse, and dark-colored meat) or PSE (white, soft, and exudative meat). For pasta, it can cause cracking. For seafood, it can accelerate oxidation. For fruits, it can cause them to dry out and turn brown. This severely affects the taste of the food and causes significant nutrient loss.

[0060] To address the problem of nutrient loss caused by rapid moisture loss, some methods aim to maintain humidity and reduce moisture loss by changing the direction of cold air outlets or adding covers. However, these methods do not increase the humidity of the food and are therefore ineffective. Other methods involve coating the food surface with an ice layer, which involves spraying water onto the food in the freezer compartment. To ensure sufficient water on the food surface for ice layer formation, a large amount of water is typically sprayed, resulting in excess water that needs to be drained. This requires a complex drainage system, and to prevent water accumulation and freezing, sensors and heating devices are also needed, leading to relatively high costs and hindering the widespread application of this technology.

[0061] The following reference Figures 1 to 12 This explains how the refrigerator of the present invention solves the above-mentioned technical problems.

[0062] Reference Figure 1 As shown, the refrigerator of this embodiment includes a drawer 101 and a humidifier 102. The humidifier 102 is located above the drawer 101, and the water mist generated by the humidifier 102 enters the storage space of the drawer 101 to humidify the food inside. Furthermore, a shelf 103 is provided between the drawer 101 and the humidifier 102, and the humidifier 102 is mounted on the shelf 103 so that the humidifier 102 does not interfere with the pulling out and putting in of the drawer 101.

[0063] It should be noted that the refrigerator also includes other components such as the cabinet 601 and the refrigeration system. These components are well known to those skilled in the art. In order to more clearly show the inventive points of the embodiments of the present invention, therefore... Figure 1 The aforementioned components will be hidden.

[0064] Reference Figures 2 to 4As shown, the humidification device 102 of this embodiment includes a base box 201, a blower 202, a humidifying element 203, and a liquid filling assembly 204. The humidifying element 203 can be a humidifying membrane or a component made of humidifying materials such as plant fibers, glass fibers, and polymer fibers. The humidifying element 203 can absorb liquid and accumulate it for a period of time, while also washing and filtering the air. The liquid filling assembly 204 can be positioned above or to the side of the humidifying element 203. Liquid is controlled to flow from the liquid filling assembly 204 to replenish the humidifying element 203, keeping it humidified. The blower 202 is a mechanical device, such as a fan, that forces convection of the gas medium inside the chamber. The airflow generated by the blower 202 blows towards the humidifying element 203, and after passing through the humidifying element 203, the airflow carries away the moisture on the humidifying element 203, forming a water mist. The base box 201 is provided with a first air inlet 301 and a first air outlet 302. Under the action of the blower 202, air enters from the first air inlet 301, forming an airflow that blows towards the humidifier 203. After passing through the humidifier 203, the air is blown out from the first air outlet 302, forming a water mist that enters the drawer 101, increasing the humidity inside the drawer 101. The blower 202, the humidifier 203, and the liquid filling assembly 204 are all mounted on the base box 201, forming a whole, which facilitates overall assembly and disassembly.

[0065] It should be noted that in some other embodiments, the bottom box 201, the blower 202, the humidifier 203 and the liquid filling assembly 204 can also be installed on the shelf 103 respectively, becoming independent modules, and no specific limitation is made here.

[0066] Reference Figure 2 and Figure 4As shown, the bottom box 201 forms an installation space, and the blower 202, humidifier 203, and liquid filling assembly 204 are all installed inside the bottom box 201. The first air inlet 301 and the first air outlet 302 are located at the bottom of the bottom box 201. That is, the bottom box 201 is provided with a first mounting position 205, a second mounting position 206, and a third mounting position 207. The humidifier 203 is installed at the first mounting position 205, the blower 202 is installed at the second mounting position 206, and the liquid filling assembly 204 is installed at the third mounting position 207. The first mounting position 205 is located near the first air outlet 302 so that the airflow passes through the humidifier 203 and flows directly into the drawer 101 through the first air outlet 302. The second mounting position 206 is located near the first mounting position 205 so that the airflow generated by the blower 202 can be directly blown onto the humidifier 203, avoiding airflow loss caused by an excessively long path. The third mounting position 207 is located on the side of the second mounting position 206 away from the first mounting position 205, thereby preventing the liquid filling assembly 204 from blocking the airflow blown out by the blower 202. Of course, the third mounting position 207 can also be located adjacent to the first mounting position 205. The first mounting position 205, the second mounting position 206, and the third mounting position 207 are arranged in one direction, which makes the overall shape of the humidification device 102 more regular and easier to manufacture.

[0067] Understandably, the bottom box 201 is also provided with a water storage section 401, and the third mounting position 207 is located above the water storage section 401, so that the liquid flowing out of the liquid adding component 204 enters the water storage section 401. The water storage section 401 is connected to the first mounting position 205, and the liquid in the water storage section 401 flows to the first mounting position 205 and is absorbed by the humidifying element 203, thus completing the replenishment of the humidifying element 203 by the liquid adding component 204.

[0068] Reference Figure 3 As shown, it can be understood that since the blower 202 is located between the humidifier 203 and the liquid filling assembly 204, in order to connect the water storage part 401 with the first mounting position 205, a connecting channel (not shown in the figure) can be opened below or to the side of the second mounting position 206, so that the liquid in the water storage part 401 can flow to the first mounting position 205 along the connecting channel.

[0069] Reference Figure 3As shown, it can be understood that the blower 202 is located in the middle of the base box 201 in the front-rear direction, the humidifier 203 is located behind the blower 202, and the first air outlet 302 is located behind the humidifier 203. The humidifier 203 and the three side walls and bottom wall of the base box 201 define a mist storage chamber 303, and the first air outlet 302 is located at the bottom of the mist storage chamber 303. The liquid filling assembly 204 is located in front of the blower 202, and the first air inlet 301 is located on the left side of the blower 202. The blower 202 is provided with a second air inlet 304 and a second air outlet 305. The second air inlet 304 faces the first air inlet 301, and the second air outlet 305 faces the humidifier 203.

[0070] Understandably, after the blower 202 is started, the air in the drawer 101 enters the blower 202 sequentially from the first air inlet 301 and the second air inlet 304, and then is blown out from the second air outlet 305. After passing through the humidifier 203, it enters the mist storage chamber 303 and then flows out from the first air outlet 302, and the water mist enters the drawer 101.

[0071] Reference Figure 2 and Figure 4 As shown, it can be understood that the first mounting position 205 is a slot, and the humidifier 203 can be inserted into the slot in the vertical direction. Furthermore, compared to the humidifier 203 covering the first air outlet 302, Figure 2 The humidifier 203 shown is positioned directly opposite the second air outlet 305 of the blower 202. Its advantage lies in its orientation: the humidifier 203 is positioned perpendicular to the air outlet direction of the blower 202, making it easier for the airflow from the blower 202 to produce water mist, thus improving the humidification effect. In contrast, if the humidifier 203 were positioned covering the first air outlet 302, i.e., parallel to the air outlet direction of the blower 202, a higher gas pressure would be required for the airflow to pass through it.

[0072] Reference Figure 2 and Figure 3 As shown, the humidifier 102 also includes a mounting bracket 208, on which the blower 202 is mounted. The mounting bracket 208 is installed in the base box 201. The mounting bracket 208 includes a clearance portion 209 and a guide portion 210. The clearance portion 209 is a recess on the left side of the mounting bracket 208, which avoids the first air inlet 301. The left and right sides of the guide portion 210 abut against the two side walls of the base box 201, and the sides of the guide portion 210 separate the first air inlet 301 and the humidifier 203, preventing the airflow blown by the blower 202 from flowing back to the first air inlet 301 and forming a closed loop.

[0073] Reference Figure 1 and Figure 2As shown, the humidifier 102 also includes a cover plate that closes onto the base box 201 to reduce airflow leakage. More specifically, the cover plate includes a lid 104 and a flip cover 105. The lid 104 closes onto the base box 201 and remains closed. The lid 104 is located above the blower 202, the humidifier 203, the first air outlet 302, and the first air inlet 301. The flip cover 105 is located above the liquid filling assembly 204. The rear side of the flip cover 105 is rotatably connected to the lid 104, allowing the flip cover 105 to be opened separately to remove or insert the liquid filling assembly 204 without having to open the entire cover, making it more convenient to use.

[0074] Reference Figure 1 and Figure 2 As shown, it can be understood that a liquid level window 106 is also provided on the side of the bottom box 201. The position of the liquid level window 106 corresponds to the position of the box body 601. The liquid level window 106 makes it easy for users to observe the remaining liquid level. When the liquid level is insufficient, the liquid filling component 204 can be taken out in time to replenish the liquid.

[0075] Reference Figure 4 As shown, the shelf 103 includes a foam layer 402, within which an air inlet channel 403 and an air outlet channel 404 are provided. One end of the air inlet channel 403 connects to a first air inlet 301, and the other end connects to the interior of the drawer 101. One end of the air outlet channel 404 connects to a first air outlet 302, and the other end connects to the interior of the drawer 101. The foam layer 402 serves as insulation, reducing heat exchange between the interior of the drawer 101 and the external environment where the humidifier 102 is located. For example, when the drawer 101 is located in a variable temperature compartment where the temperature can reach 0 degrees Celsius, and the humidifier 102 is placed in a refrigerator compartment, the foam layer 402 can reduce heat transfer, preventing the liquid in the humidifier 102 from freezing and causing the humidifier 102 to malfunction.

[0076] It should be noted that the material of foam layer 402 can also be replaced by other insulation materials to form an insulation layer and achieve the function of insulation.

[0077] Reference Figure 4 As shown, it can be understood that multiple baffles 405 are provided in both the air inlet channel 403 and the air outlet channel 404. The baffles 405 divide the air inlet channel 403 and the air outlet channel 404 into multiple small channels. On the one hand, they can form a grid structure to block falling foreign objects; on the other hand, they reduce the connected area and reduce the impact of heat.

[0078] Reference Figure 4As shown, it can be understood that the partition 405 is arranged along the gas flow direction, that is, the gas flows in the vertical direction, and the partition 405 is also arranged in the vertical direction. Furthermore, the gas flow is not necessarily strictly vertical; it can follow a certain slope or curve. Therefore, the partition 405 being arranged along the gas flow direction also includes the partition 405 being inclined or curved, as long as it can achieve gas flow at both ends of the foam layer 402, thus realizing air circulation between the humidifier 102 and the drawer 101.

[0079] It should be noted that in some other embodiments, only one partition 405 may be provided in the air inlet channel 403, and no partition 405 may be provided in the air outlet channel 404; or no partition 405 may be provided in the air inlet channel 403, and a partition 405 may be provided in the air outlet channel 404.

[0080] Reference Figures 4 to 6 As shown, the liquid filling assembly 204 includes a housing 601. The bottom of the housing 601 is equipped with a drain valve and a water outlet 501. The drain valve is a normally closed valve body. When the housing 601 is separated from the base box 201, the drain valve closes, and the water outlet 501 is in a closed state, allowing the user to pre-fill water into the housing 601 before placing the housing 601 onto the base box 201. When the housing 601 is connected to the base box 201, the drain valve is triggered to open. At this time, the water outlet 501 is in a conductive state, allowing water from the housing 601 to flow to the drain valve and be discharged into the water storage section 401 of the base box 201. This eliminates the need for manual operation and makes it more convenient to use.

[0081] Reference Figure 5 and Figure 6As shown, the drain valve includes a valve seat, a valve core 503, a sealing ring 504, and a reset elastic element 505. The valve seat is located at the lower end of the outlet 501. The valve core 503 is slidably disposed within the valve seat. The sealing ring 504 is sleeved on the valve core 503 and used to seal the outlet 501. The reset elastic element 505 is sleeved on the valve core 503. A mounting boss 507 is provided at one end of the valve core 503 away from the outlet 501. One end of the reset elastic element 505 abuts against the mounting boss 507, and the other end abuts against the valve seat. The water storage part 401 is provided with a protrusion 509, which abuts against the valve core 503 so that the valve core 503 moves upward to open the outlet 501. When the housing 601 is placed on the base box 201, the lower end of the valve core 503 abuts against the protrusion 509, restricting the valve core 503 from moving further downward, while the housing 601 can continue to move downward. This causes the valve core 503 to move upward relative to the outlet 501, and drives the sealing ring 504 to disengage from the outlet 501, thereby opening the outlet 501. When the housing 601 is removed, the housing 601 can move upward, while the valve core 503, under the action of the reset elastic element 505, initially still abuts against the protrusion 509, thus moving downward relative to the outlet 501, closing the outlet 501, and preventing liquid from flowing out when the housing 601 is removed.

[0082] It is understood that in some other embodiments, the drain valve may also be configured to include a valve core 503, a sealing ring 504, and a reset elastic element 505. The sealing ring 504 is sleeved on the valve core 503 and is used to seal the outlet 501. The reset elastic element 505 generates a downward force, pushing the valve core 503 to close the outlet 501. When the housing 601 is placed on the base box 201, the lower end of the valve core 503 is touched and pushed upward, causing the valve core 503 to open the outlet 501, thereby achieving rapid opening.

[0083] Reference Figure 5 and Figure 6 As shown, the valve seat includes a threaded seat 502 and a cap 506. The threaded seat 502 is fixed to the housing 601 and has a threaded portion on its outer periphery. The cap 506 is threadedly connected to the threaded portion. The threaded seat 502 has an outlet hole communicating with the outlet 501. The cap 506 has a mounting portion 508 located in the outlet hole. The mounting portion 508 has a guide hole that mates with the valve core 503. The valve core 503 is slidably disposed in the guide hole. One end of the reset elastic member 505 abuts against the mounting boss 507, and the other end abuts against the mounting portion 508. Therefore, the valve core 503, the sealing ring 504, and the reset elastic member 505 are connected together with the cap 506 to form a detachable component. When the cap 506 is removed, the valve core 503, the sealing ring 504, and the reset elastic member 505 can be removed together for easy replacement and cleaning.

[0084] Understandably, the housing 601 is configured as a sealed structure, meaning that when the drain valve is closed, the housing 601 does not allow air circulation to the outside, thus ensuring that the air pressure in the housing 601 is not equal to atmospheric pressure. When the housing 601 is placed on the base box 201, the bottom surface of the drain valve is located inside the water storage section 401, allowing the liquid level in the water storage section 401 to be higher than the bottom surface of the drain valve. When the drain valve opens, the liquid inside the housing 601 flows out, increasing the internal space of the housing 601 and thus reducing the internal air pressure. When the liquid level in the water storage section 401 is higher than the bottom surface of the drain valve, meaning the internal air pressure of the housing 601 is less than atmospheric pressure, the gas pressure overcomes the gravity of the liquid, preventing further outflow of liquid from the housing 601, thus forming a liquid seal.

[0085] Reference Figure 6 As shown, it can be understood that a handle 602 is also connected to the box body 601. The box body 601 is provided with a stepped receiving groove. When the handle 602 is placed in the receiving groove, it will not protrude from the side of the box body 601, reducing the overall space occupied. When needed, the handle 602 will be rotated from the outside to the top of the box body 601, so that the box body 601 can be lifted.

[0086] Reference Figures 7 to 9 As shown, it can be understood that the upper end of the bottom box 201 has an opening, and the liquid filling component 204 is fitted as a whole over the opening of the bottom box 201, with the liquid flowing directly from the liquid filling component 204 onto the humidifier 203. To increase the contact area, the humidifier 203 is placed horizontally and covers the first air outlet 302.

[0087] It should be noted that in some other embodiments, the humidifying element 203 can also be positioned at the upper end of the bottom box 201, that is, the humidifying element 203 is close to the liquid filling component 204. The airflow blown by the blower 202 passes over the lower surface of the humidifying element 203, accelerating the evaporation of liquid on the lower surface of the humidifying element 203 and carrying away a certain amount of moisture to form a water mist. The humidifying element 203 can also be positioned at the upper end of the bottom box 201, which also facilitates disassembly and cleaning. That is, after removing the liquid filling component 204, the humidifying element 203 can be disassembled separately, providing ample operating space and a simple and convenient disassembly and assembly process. In some other embodiments, the humidifying device 102 may include two humidifying elements 203, which are respectively positioned at the upper end and the bottom of the bottom box 201. That is, the two humidifying elements 203 are arranged in layers along the vertical direction, which can increase the evaporation area and increase the humidification capacity.

[0088] Reference Figure 10 and Figure 11As shown, the liquid filling assembly 204 includes a housing 601, which has a third air inlet 1201 and multiple micro-holes 1202 located above the humidifying element 203. The third air inlet 1201 is used to communicate with the outside air. The liquid filling assembly 204 also includes a control switch 1203, which is used to control the opening and closing of the third air inlet 1201. The housing 601 is configured as a sealed structure, that is, when the control switch 1203 is closed, the housing 601 does not allow air circulation with the outside air, so that the air pressure in the housing 601 is not equal to atmospheric pressure. When the control switch 1203 is turned on, the third air inlet 1201 is in the open state, and the housing 601 is connected to the outside atmosphere. This allows the liquid inside the housing 601 to flow out naturally from the micropores 1202 due to gravity. When the control switch 1203 is turned off, the third air inlet 1201 is in the closed state, and the housing 601 is isolated from the outside atmosphere. That is, the air pressure inside the housing 601 is lower than the atmospheric pressure, and the surface tension of the micropores 1202 is greater than the air pressure inside the housing 601. This prevents the liquid inside the housing 601 from continuing to flow out, forming a liquid seal.

[0089] It is understandable that the control switch 1203 can be a miniature solenoid valve or a miniature vacuum pump. The miniature solenoid valve or miniature vacuum pump controls the airtightness of the housing 601, allowing the liquid in the housing 601 to flow out through the micro-holes 1202 at the bottom of the housing 601 and drip onto the humidifying element 203, where it is absorbed. For example, when the miniature solenoid valve is open, the external atmosphere is connected to the housing 601. When the atmospheric pressure is greater than the surface tension of the micro-holes 1202, the water in the housing 601 flows out through the micro-holes 1202. When the miniature solenoid valve is closed, the external atmosphere is isolated from the housing 601, and the surface tension of the micro-holes 1202 is greater than the air pressure inside the housing 601 (forming a liquid seal), and the liquid in the housing 601 stops flowing out.

[0090] Reference Figure 12As shown, the housing 601 contains a liquid storage chamber 1204 and a mounting chamber 1205. The liquid is stored in the liquid storage chamber 1204, and micropores 1202 are located at the bottom of the liquid storage chamber 1204. The liquid filling assembly 204 also includes a sealing strip 1206 and a cover 1207. The cover 1207 is fitted onto the housing 601 to cover the liquid storage chamber 1204 and the mounting chamber 1205. The sealing strip 1206 is arranged around the outer periphery of the liquid storage chamber 1204 to achieve a seal. It is understood that the housing 601 is configured as a sealed structure, meaning that when the control switch 1203 is closed, the liquid storage chamber 1204 does not allow air circulation to the outside, ensuring that the air pressure in the liquid storage chamber 1204 is not equal to atmospheric pressure. The control switch 1203 is located in the mounting cavity 1205. A fourth air inlet 1208 is also provided on the side wall of the mounting cavity 1205. The third air inlet 1201 connects the liquid storage cavity 1204 and the mounting cavity 1205, while the fourth air inlet 1208 connects to the outside air and the mounting cavity 1205. One end of the control switch 1203 is connected to the third air inlet 1201 via a connecting air pipe 1212, and the other end is connected to the fourth air inlet 1208. By placing the control switch 1203 in the mounting cavity 1205 and connecting it to the outside air via the fourth air inlet 1208, the housing 601 can protect the control switch 1203, preventing liquid from entering and damaging it when adding liquid. Meanwhile, the control switch 1203 can be removed and placed together with the housing 601. Therefore, when changing or replenishing the liquid in the liquid storage chamber 1204, it is not necessary to repeatedly disconnect and reconnect the third air inlet 1201 and the control switch 1203, which makes it more convenient for users and improves the user experience.

[0091] Reference Figure 12 As shown, the cover 1207 has a liquid inlet 1209, and a sealing plug 1210 is installed on the liquid inlet 1209. The sealing plug 1210 seals the liquid inlet 1209, ensuring that the liquid storage chamber 1204 is in a closed state and not connected to the outside air. The user can directly pull out the sealing plug 1210 to add liquid, and after adding liquid, insert the sealing plug 1210 back into the liquid inlet 1209 to complete the seal.

[0092] Reference Figure 12 As shown, it can be understood that the box body 601 and the bottom box 201 can also be set as one piece, that is, the sides of the box body 601 and the bottom box 201 are integrated, and the top and bottom ends are respectively provided with the box cover 1207 and the bottom cover 1211, which facilitates the installation of components such as the blower 202 and the humidifier 203.

[0093] Reference Figure 8 and Figure 9As shown, it can be understood that the humidification device 102 of this embodiment also includes a control board 801, which is electrically connected to a control switch 1203. The control board 801 is used to control the opening or closing of the control switch 1203. For example, the control board 801 is located at the bottom box 201, and a power supply electrode 1001 is connected to the upper end of the control board 801. A metal contact 1002 is provided at the bottom of the liquid filling assembly 204, and the metal contact 1002 is connected to the control switch 1203. When the liquid filling assembly 204 is placed at the bottom box 201, the power supply electrode 1001 contacts the metal contact 1002 to achieve a conductive effect, and the control board 801 can control the control switch 1203 to open or close.

[0094] It is understandable that by cooperating with the power supply electrode 1001 and the metal contact 1002, the liquid filling component 204 can be de-energized when the liquid filling component 204 is removed for liquid replenishment, thus enabling non-energized operation and facilitating user use.

[0095] It should be noted that the control board 801 can also be installed separately inside the refrigerator, and the humidifier 102 can be used as a detachable modular unit.

[0096] It is understood that in the refrigerator of this embodiment of the invention, drawer 101 can be placed in the refrigerator compartment or the variable temperature compartment.

[0097] When drawer 101 is placed in the refrigerator compartment, a regular shelf 103 is placed above drawer 101. A humidifying device 102, as described in this embodiment, is installed on shelf 103. The blower 202 built into the humidifying device 102 blows out the moisture adsorbed on the humidifying element 203, forming a water mist. This water mist enters the drawer 101, increasing the humidity inside. Because the water mist is formed by airflow carrying moisture, compared to directly spraying water from a nozzle, the diameter of the mist droplets can be refined, reducing the amount of water falling on the drawer 101 wall, thereby reducing frost or ice formation on the drawer 101 wall and lowering the possibility of food sticking together.

[0098] When drawer 101 is placed in the variable temperature compartment, a shelf 103 with a foam layer 402 is placed above drawer 101. A humidification device 102 according to this embodiment is mounted on shelf 103, and the humidification device 102 is located in the refrigerator compartment. Since the temperature range of the variable temperature compartment is around 0 degrees Celsius, there is a risk that the liquid in the humidification device 102 will freeze. By placing the humidification device 102 in the refrigerator compartment, where the temperature range is greater than 0 degrees Celsius, the risk of the humidification device 102 being affected by freezing or frost can be reduced. Furthermore, the foam layer 402 on shelf 103 can isolate the variable temperature compartment from the refrigerator compartment, reducing heat exchange between them.

[0099] The following describes an embodiment in which drawer 101 is placed in a variable temperature compartment.

[0100] Understandably, when drawer 101 is in the off-peak warm-up phase, the food's temperature rises much slower than the temperature rise of the drawer's inner wall and the air inside. At this time, humidification is applied to the air. When this relatively warm and humid air comes into contact with the cool food surface, the water molecules in the air, due to the decrease in saturated vapor pressure, condense from a gaseous state into a liquid state and adhere to the food surface. When the machine enters the on-peak cooling phase, the liquid water molecules on the food surface condense into a solid ice film, which inhibits the drying of moisture inside the food and isolates microorganisms and oxygen, achieving color preservation and oxidation inhibition.

[0101] It is understandable that since the humidifier 102 is located in the refrigerator compartment, and the temperature of the refrigerator compartment is always higher than that of the drawer 101, the blower 202 draws in the cool air with lower humidity from the drawer 101 into the humidifier 102, and blows it toward the humidifier 203, where it becomes hot air with higher humidity. The heated air can hold more water vapor, and the hot air then flows back to the drawer 101 through the first air outlet 302 of the bottom box 201 to achieve humidification.

[0102] It is understood that, due to the use of the humidification device 102 of the present invention to produce mist, the liquid falling on the surface of the food is more uniform, the flow rate adhering to the food is easier to control, and the liquid flowing outside the food is reduced, thereby achieving the purpose of avoiding the use of a drainage structure.

[0103] This invention provides a method for controlling a refrigerator. The structure or components of the refrigerator have been described in detail in the above embodiments and will not be repeated here. Furthermore, the control method of this invention is not limited to the solutions described in the above embodiments. (Refer to...) Figure 13 As shown, the ice coating control method of this embodiment includes, but is not limited to, step S1310.

[0104] In step S1310, when the temperature of the variable temperature chamber continues to decrease and the humidity value of the variable temperature chamber is less than the set value, the humidification device is turned on and the blower is running at the first speed.

[0105] When the user activates the ice coating function, the temperature and humidity sensors in the variable temperature compartment drawer monitor the temperature and humidity levels in real time. When the temperature continuously decreases and the humidity drops to a specific threshold within a given time period (determining the drawer to be in a cooling, low-humidity state), the refrigerator automatically activates the humidification device to continuously humidify the drawer and suppress dehydration caused by the cooling process of food. When the temperature in the variable temperature compartment falls below freezing, the sprayed mist quickly forms a thin layer of ice on the surface of the food, encapsulating it and preventing moisture loss. This significantly reduces food dehydration and avoids the problems of ice crystal sublimation, dehydration, and oxidation that can occur when frozen foods are stored in the refrigerator. Simultaneously, the ice coating prevents air from contacting the food, preventing adverse oxidation reactions, avoiding spoilage, and preserving the nutritional value of the food.

[0106] The ice coating mode activation signal can be issued by the user through the control panel, buttons, remote control, or other refrigerator control components as needed. The refrigerator controller (not shown in the figure) can then receive the ice coating mode activation signal issued by the user. Alternatively, the ice coating mode activation signal can also be issued by a detection element that detects the presence of food in the freezer compartment. For example, a weighing device (not shown in the figure) can be installed at the bottom of the freezer compartment to detect the weight of the stored food. The weighing device is electrically connected to the controller. If the detected weight is greater than zero, it indicates that there is food in the freezer compartment, and the signal is fed back to the controller, thus issuing the ice coating mode activation signal. Alternatively, an infrared detector can be used to detect the presence of food in the freezer compartment. The infrared detector is electrically connected to the controller. If the infrared detector detects the presence of food in the freezer compartment, it feeds back a signal to the controller, allowing the controller to receive the ice coating mode activation signal issued by the detection element.

[0107] Alternatively, the ice coating mode activation signal can be issued through a combination of the two methods mentioned above. That is, when the user issues the first ice coating mode activation signal via the control panel, buttons, remote control, or other refrigerator control components, and simultaneously the detection element detects food in the freezer compartment and issues a second ice coating mode activation signal, the controller can then truly receive the ice coating mode activation signal, thus avoiding accidental operation. The specific method of issuing the ice coating signal is not limited here.

[0108] Another embodiment of the present invention also provides a method for controlling the icing coating, such as... Figure 14 As shown, the ice coating control method of this embodiment includes, but is not limited to, step S1410.

[0109] Step S1410: When the temperature of the variable temperature chamber continues to rise, the humidification device is turned on, and the blower operates at a second speed, which is greater than the first speed.

[0110] When the refrigerator detects a continuous rise in temperature in the drawer over a given time, it automatically switches the humidifier's blower to a high-speed operation mode. Since the air inside the drawer heats up faster than the food surface, increasing the blower's speed allows the humid air to condense onto the food surface more quickly, forming an ice coating and further inhibiting oxidation and dehydration.

[0111] See Figure 15 As shown, a specific example illustrates the ice-coating mode, in which the humidification device used is... Figure 2 In the embodiment shown, the blower is selected as a fan. Figure 15 The flowchart shown illustrates the ice coating mode. Upon activation, the drawer temperature is monitored. If there is no continuous cooling, it indicates the drawer temperature is rising or remaining constant, which is unfavorable for ice coating formation. In this case, the fan is turned on and operates at high speed to condense the humid air onto the food surface more quickly, forming the ice coating. When the drawer temperature continues to cool, the humidity level is checked to see if it reaches the set humidity threshold. If it does, surface humidification is unnecessary, the fan stops, and the process returns to monitoring the drawer temperature. If the humidity level does not reach the set threshold, the fan is turned on and maintains normal speed. In this state, the drawer is simultaneously cooling and humidifying, resulting in a cooling, low-humidity state. The humidifier fan is activated and operates at normal speed to humidify and suppress dehydration during food cooling.

[0112] See Figure 16 As shown, a specific example illustrates the ice-coating mode, in which the humidification device used is... Figure 8 In the embodiment shown, the blower is selected as a fan. Figure 16The flowchart shown illustrates the ice coating mode. Upon activation, the drawer temperature is monitored. If there's no continuous cooling, the drawer temperature is either rising or remaining constant, hindering ice coating formation. In this case, the fan is turned on and operates at high speed, while the micro-solenoid valve activates, allowing the humidifier to deliver high-humidity air into the drawer. Under high-speed fan operation, this air condenses more quickly onto the food surface, forming an ice coating. While the drawer temperature continues to cool, the humidity level is checked to ensure it reaches the set humidity threshold. If it does, surface humidification is unnecessary, and the fan and micro-solenoid valve stop working, returning to the temperature monitoring step. If the humidity level doesn't reach the set threshold, the fan and micro-solenoid valve are activated, maintaining normal fan speed. In this state, the drawer is simultaneously cooling and humidifying, resulting in a cooling, low-humidity state. The humidifier fan operates at normal speed, achieving humidification and suppressing moisture loss during food cooling.
