[0003] This application relates to the field of refrigeration equipment technology, and particularly to refrigeration equipment, control methods, control devices and storage media. Background Technology

[0004] In related technologies, some refrigeration equipment has a temperature sensor installed at the bottom of the storage container to detect the temperature of the food inside. Since the temperature sensor needs to be connected to the circuit control board inside the refrigeration equipment through wires, the temperature sensor will move with the storage container when the user takes it out. This requires a long wire to move with the storage container, resulting in a large amount of wires and increased manufacturing costs. Summary of the Invention

[0005] This application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a refrigeration device, control method, control apparatus, and storage medium. By arranging a first temperature sensor at the rear of a first storage container, and ensuring that the first temperature sensor does not move with the first storage container, the length of the wire is shortened, thereby reducing the amount of wire used and lowering manufacturing costs.

[0018] According to some embodiments of this application, the second storage container includes a front wall, which is inclined and has a front air vent, through which at least a portion of the airflow in the second storage container enters the first storage container.

[0019] According to some embodiments of this application, the first storage container further includes a second insulation layer and an outer cavity. The second insulation layer covers the outer wall of the inner cavity, and the outer cavity covers the outer wall of the second insulation layer. The outer cavity is provided with a first clearance hole to avoid the first temperature sensor, and the second insulation layer is provided with a second clearance hole to avoid the first temperature sensor.

[0020] According to some embodiments of this application, the outer wall of the inner cavity is provided with a positioning part, the second heat-conducting part is embedded between the positioning part and the inner cavity, the positioning part is provided with a third clearance hole to avoid the first temperature sensor, the positioning part passes through the second clearance hole and abuts against the inner wall of the first clearance hole.

[0021] According to a control method for a refrigeration device based on a second aspect of this application, the refrigeration device includes a housing, a door, a first storage container, and a first temperature sensor. The housing has a refrigeration space and an opening communicating with the refrigeration space. The door is used to close or open. The first storage container is movably disposed in the refrigeration space. The first storage container has a heat-conducting component and an inner cavity. The inner cavity has a storage space. The heat-conducting component includes a first heat-conducting part and a second heat-conducting part. The first heat-conducting part is attached to the bottom of the inner cavity, and the second heat-conducting part is disposed on the side of the inner cavity away from the opening. The first temperature sensor is disposed on the side of the refrigeration space away from the opening and is used to abut against the second heat-conducting part. The control method includes:

[0022] A first signal is acquired, and the temperature of the cooling space is controlled according to a first preset temperature, wherein the first signal indicates that the temperature control function is detected to be activated and the cabinet door is closed;

[0023] A second signal is acquired, and the temperature of the cooling space is controlled according to a second preset temperature. The second signal is characterized by the first temperature sensor detecting a value that is continuously greater than the target temperature for a first preset duration, wherein the first preset temperature is less than or equal to the target temperature and greater than the second preset temperature.

[0024] The control method of the refrigeration equipment according to the embodiments of this application has at least the following beneficial effects: In terms of structure, by setting the first temperature sensor on the side of the refrigeration space away from the opening, it can be understood that the first temperature sensor is set on the back of the inner wall of the refrigeration space. Compared with the related technology of setting the temperature sensor at the bottom of the drawer, when the user takes out the first storage container, the first temperature sensor does not move with the first storage container, thereby shortening the length of the wire and achieving the technical effect of reducing costs. At the same time, by arranging the first heat-conducting part and the second heat-conducting part in the inner cavity of the first storage container, when the first storage container slides into the refrigeration space, that is, when the first storage container is in the closed position, the first temperature sensor abuts against the second heat-conducting part, and the food in the inner cavity comes into contact with the first heat-conducting part. The temperature of the food can be sequentially conducted to the first temperature sensor through the first heat-conducting part and the second heat-conducting part, thereby realizing the detection of the temperature of the food.

[0025] Regarding the control method, when the first signal is received, it indicates that the temperature control function has been activated and the door is closed. At this time, the refrigeration equipment controls the temperature of the refrigeration space according to the first preset temperature, so that the temperature of the refrigeration space is maintained at the first preset temperature. When the second signal is received, the detection value of the first temperature sensor is continuously greater than the target temperature for a first preset time period, indicating that the temperature at the bottom of the food cannot reach the target temperature for a long time. This indicates that the user has just put in the food, the food temperature is high, or the amount of food is large. In order to ensure the preservation effect, it is necessary to cool down quickly. At this time, the refrigeration equipment controls the temperature of the refrigeration space according to the second preset temperature. The second preset temperature is lower than the first preset temperature, which can accelerate the cooling rate and improve the preservation effect of the food.

[0026] According to some embodiments of this application, the control method further includes:

[0027] Obtain the cumulative duration of temperature control according to the second preset temperature;

[0028] When the cumulative duration is less than the second preset duration, the temperature is controlled according to the first preset temperature;

[0059] Referring to Figure 1, a refrigeration device 1000 is provided in an embodiment of this application. The refrigeration device 1000 can be a refrigerator or freezer, etc. The following description mainly uses a refrigerator as an example. The refrigeration device 1000 includes a cabinet 100, a first storage container 200 and a first temperature sensor 500. The cabinet 100 is provided with a refrigeration space 110. The cabinet 100 is also provided with an opening 111 communicating with the refrigeration space 110. The refrigeration device 1000 also includes a door 160. After opening the door 160, the refrigeration space 110 is exposed through the opening 111. Food can be put into the refrigeration space 110 through the opening 111. A first storage container 200 is slidably disposed within a cooling space 110. The first storage container 200 includes a heat-conducting element 210 and an inner cavity 220. The inner cavity 220 provides storage space. The heat-conducting element 210 includes a first heat-conducting part 211 and a second heat-conducting part 212. The first heat-conducting part 211 is attached to the bottom of the inner cavity 220 and covers the bottom of the first storage container 200. The second heat-conducting part 212 is located on the side of the inner cavity 220 away from the opening 111, at the rear of the first storage container 200. Food inside the first storage container 200 comes into contact with the first heat-conducting part 211, and the temperature of the food can be transferred to the second heat-conducting part 212 through the first heat-conducting part 211. A first temperature sensor 500 is located on the side of the cooling space 110 away from the opening 111 and detects the temperature of the bottom of the inner cavity 220 by contacting the second heat-conducting part 212.

[0060] In this embodiment, by placing the first temperature sensor 500 on the side of the cooling space 110 away from the opening 111, it can be understood as placing the first temperature sensor 500 on the back of the inner wall of the cooling space 110. Compared with the related technology where the temperature sensor is placed at the bottom of the drawer, the distance between the first temperature sensor 500 and the control board can be shortened. When the user takes out the first storage container 200, the first temperature sensor 500 will not move with the first storage container 200, thereby shortening the length of the wire and achieving the technical effect of reducing costs. At the same time, By arranging a heat-conducting element 210 in the inner cavity 220 of the first storage container 200, the heat-conducting element 210 includes a first heat-conducting part 211 and a second heat-conducting part 212. When the first storage container 200 slides into the cooling space 110, the first temperature sensor 500 comes into contact with the second heat-conducting part 212. When the user places food into the first storage container 200, the food comes into contact with the first heat-conducting part 211. The temperature of the food can be sequentially conducted to the first temperature sensor 500 through the first heat-conducting part 211 and the second heat-conducting part 212, thereby realizing the detection of the temperature of the food.

[0061] In related technologies, the first temperature sensor 500 is located at the bottom of the first storage container 200. Since the first temperature sensor 500 moves with the first storage container 200 during the pulling process, the wire connected to the first temperature sensor 500 is also pulled out when the first storage container 200 is removed. This causes friction between other components and the wire, resulting in significant wear and tear on the wire. Furthermore, the movement resistance of the first storage container 200 increases, making operation inconvenient. In this embodiment, the first temperature sensor 500 is moved to the rear of the first storage container 200. When the first storage container 200 is removed, the first temperature sensor 500 does not move with it, thus the wire is not pulled out, preventing wear on the wire and improving connection stability. The movement resistance of the first storage container 200 is also not increased, making it easier for the user to operate the first storage container 200. Additionally, the wire does not need to be led into the cooling space 110, facilitating the assembly of the first temperature sensor 500 and improving assembly efficiency.

[0062] In some embodiments of this application, the heat-conducting element 210 is configured as a metal heat-conducting plate, on which the food is placed and in direct contact with the metal heat-conducting plate. The metal heat-conducting plate is made of metal material, such as an aluminum plate, which has good thermal conductivity.

[0063] Referring to Figures 1, 2, and 4, in some embodiments, the refrigeration device 1000 uses air cooling to cool the refrigeration space 110. The refrigeration device 1000 includes an air duct structure 400, which is disposed inside the housing 100 and located at the back of the refrigeration space 110. The air duct structure 400 is provided with an air supply channel 410, which supplies air to the refrigeration space 110. A first evaporator and a fan are provided in the air supply channel 410. During the refrigeration process, the fan rotates to generate airflow, thereby transferring the cooling capacity of the first evaporator to the refrigeration space 110. The air duct structure 400 is also provided with a return air inlet 430 connecting the refrigeration space 110 and the air supply channel 410. The air in the refrigeration space 110 flows back to the air supply channel 410 through the return air inlet 430, thus allowing the cold airflow to circulate.

[0064] In some embodiments, the aforementioned refrigeration space 110 is configured as a variable temperature compartment, and the first storage container 200 is configured as an ice-temperature preservation drawer. The ice-temperature preservation drawer can achieve functions such as zero-degree preservation, rapid cooling, and micro-freezing preservation. Ice-temperature storage has advantages such as short-term preservation without thawing. Referring to Figure 1, the cabinet 100 also includes a refrigerator compartment 150, which is located above the variable temperature compartment. Shelves for placing items are arranged inside the refrigerator compartment 150. Referring to Figure 2, the air duct structure 400 also includes a refrigerator channel 420, which is connected to the refrigerator compartment 150, thereby allowing air to be supplied to the refrigerator compartment 150 for cooling.

[0065] In some other embodiments, the refrigeration space 110 described above can also be configured as a freezer compartment or a refrigerator compartment 150. It should be noted that the temperature of the freezer compartment is below 0°C, the temperature of the variable temperature compartment is generally below 0°C, and the temperature of the refrigerator compartment 150 is generally above 2°C.

[0066] It should be noted that during the defrosting process of the refrigeration equipment 1000 or when the user opens the door 160, some hot air will seep into the rear of the first storage container 200.

[0067] Based on this, referring to FIG2, in some embodiments of this application, the housing 100 is provided with a mounting part 120, which is located at the back of the refrigeration space 110. The first temperature sensor 500 is mounted on the mounting part 120. The mounting part 120 can be understood as a plate structure. The mounting part 120 extends in the vertical direction. The first temperature sensor 500 can be mounted on the mounting part 120 by fasteners. The mounting part 120 can also be understood as a part of the structure of the housing 100. The mounting portion 120 is provided with a sealing element 121, which fits against the first storage container 200 and surrounds the outer periphery of the first temperature sensor 500, thereby enclosing the first temperature sensor 500. When the first storage container 200 is in the closed position, the rear side of the first storage container 200 abuts against the sealing element 121, sealing the gap between the first storage container 200 and the mounting portion 120, thus isolating the first temperature sensor 500 from the cooling space 110, achieving a sealing effect. External hot air is less likely to penetrate around the first temperature sensor 500 and affect its detection results. The sealing element 121 has a ring-shaped structure and can be configured as a sealing ring. The sealing element 121 can be made of materials such as rubber or plastic.

[0068] It should also be noted that, compared to the related technologies where the first temperature sensor 500 is located at the bottom of the first storage container 200, this embodiment places the first temperature sensor 500 on the back of the first storage container 200. When the user removes the first storage container 200, the first temperature sensor 500 will not move with the first storage container 200. If the sealing element 121 is arranged according to the related technologies, when the user removes the first storage container 200, the first temperature sensor 500 will move with the first storage container 200, causing the wire of the first temperature sensor 500 to rub back and forth with the sealing element 121, resulting in wear and easy failure of the sealing element 121. Furthermore, it will also cause greater resistance to the movement of the first storage container 200, making it difficult for the user to remove or retract the first storage container 200.

[0069] Referring to FIG1, in some embodiments of this application, the first storage container 200 is configured as a drawer, thereby forming a single drawer structure.

[0070] Referring to FIG4, in some embodiments of this application, the refrigeration device 1000 further includes a second storage container 300, which is located in the refrigeration space 110. Both the first storage container 200 and the second storage container 300 are configured as drawers, thereby forming a double drawer structure. The first storage container 200 and the second storage container 300 can be arranged one above the other. When the user needs to place or take out food, the user can choose to pull out one of the drawers.

[0071] Referring to FIG4, in some embodiments of this application, the first storage container 200 and the second storage container 300 form a layered double-drawer structure. The first storage container 200 is located below the second storage container 300, and the second storage container 300 is located inside the first storage container 200. The first storage container 200 must be removed first to reveal the second storage container 300, and only then can the second storage container 300 be retrieved. In other embodiments, the first storage container 200 may be located above the second storage container 300, and the second storage container 300 must be removed first to reveal the first storage container 200.

[0072] In some embodiments of this application, the rear side of the first storage container 200 and the second storage container 300 is provided with a return air section. The return air section can be understood as a notch or through hole, so that the cold air flow in the first storage container 200 and the second storage container 300 can flow out to the outside through their respective return air sections, and enter the air duct structure 400 from the return air port 430 on the rear side of the cooling space 110 to exchange heat with the first evaporator.

[0073] Referring to Figures 4, 6, 8, and 9, according to some embodiments of this application, the housing 100 includes a shelf 130 and an air duct fixing plate 140. The shelf 130 and air duct fixing plate 140 can be understood as generally flat structures. The shelf 130 is located within the refrigerator compartment 150. The shelf 130 is positioned above the first storage container 200, and the air duct fixing plate 140 is located between the first storage container 200 and the shelf 130. An air supply duct 141 is formed between the shelf 130 and the air duct fixing plate 140. The air supply duct 141 is connected to the air duct structure 400. The air supply channel 410 is connected, and the air duct fixing plate 140 is provided with an air outlet 1411. The air outlet 1411 is connected to the air supply channel 141 and the first storage container 200. The air outlet 1411 can be set downward. During the cooling process, the first evaporator generates cold energy, and the fan rotates to generate cold air flow. The cold air flow transfers the cold energy of the first evaporator to the first storage container 200. The cold air flow passes through the air supply channel 410 and the air supply channel 141 in sequence, and finally flows out from the air outlet 1411 and enters the first storage container 200 to cool and preserve the food in the first storage container 200.

[0074] Referring to Figure 5, in some embodiments of this application, multiple air outlets 1411 can be arranged, and the multiple air outlets 1411 are arranged at intervals along the front and rear direction of the refrigeration equipment 1000, so that the air outlet is relatively uniform.

[0075] Referring to FIG6, in some embodiments of this application, since the air supply duct 141 is located above the second storage container 300, most of the cold air flowing out from the air supply duct 141 preferentially passes through the second storage container 300 and then through the first storage container 200, making the temperature of the second storage container 300 relatively lower. During the cooling process, the temperature of the first storage container 200 is maintained at -1°C to -2°C, and the temperature of the second storage container 300 is maintained at -2°C to -3°C. The second storage container 300 is mainly used to store meat. In order to avoid freezing fish, the temperature of the fish cannot be too low, so the fish can be placed in the first storage container 200.

[0076] Referring to FIG4, in some embodiments of this application, the air duct structure 400 includes an air duct cover 440, which is located on the rear side of the first storage container 200. The air duct cover 440 extends in the vertical direction, and the first temperature sensor 500 can be installed on the air duct cover 440. It can be understood that the above-mentioned mounting part 120 is set as the air duct cover 440.

[0077] It should be noted that, since the duct cover 440 needs to undergo a foaming process to form a foam layer inside the duct structure 400, the actual installation position of the duct cover 440 may be offset from the design after the foaming process. Furthermore, since the duct cover 440 does not directly form an assembly relationship with the first storage container 200, if the position of the duct cover 440 is offset, the first temperature sensor 500 may easily interfere with the first storage container 200, causing the first storage container 200 to fail to be pushed into place. Alternatively, after the first storage container 200 is pushed into the cooling space 110, the first temperature sensor 500 may move away from the first storage container 200 and fail to contact the second heat-conducting part 212, resulting in inaccurate temperature detection.

[0078] Based on this, referring to Figures 3 and 9, in some embodiments of this application, the air duct fixing plate 140 is provided with a mounting plate 142. The mounting plate 142 is located on the side of the first storage container 200 away from the opening 111, that is, the mounting plate 142 is located on the rear side of the first storage container 200. The mounting plate 142 extends in the vertical direction, and the other parts of the air duct fixing plate 140 extend in the horizontal direction. The first temperature sensor 500 is mounted on the mounting plate 142. It can be understood that the aforementioned mounting part 140 is set as the mounting plate 142. In this embodiment, since the air duct fixing plate 140 and the first storage container 200 are in a strong assembly relationship, the displacement tolerance is better controlled. Therefore, mounting the first temperature sensor 500 on the mounting plate 142 can ensure that the displacement of the first temperature sensor 500 in the actual product will not have a large deviation, the first temperature sensor 500 will not move away from the first storage container 200 or interfere with the first storage container 200, and the temperature detection result is more accurate.

[0079] Referring to Figures 8 and 9, according to some embodiments of this application, the air duct fixing plate 140 is provided with a sealing part 143. The sealing part 143 can be understood as a part of the structure of the air duct fixing plate 140. The main structure of the air duct fixing plate 140 extends horizontally, and the sealing part 143 extends downward and in the front-back direction. Since the first storage container 200 is set as a drawer, the top of the first storage container 200 is provided with a first opening 223. The first opening 223 is square, and the user puts food into the first storage container through the first opening 223. Inside container 200, when the first storage container 200 is in the closed position, the sealing part 143 is located on the outer periphery of the first opening 223, and the lower edge of the sealing part 143 is lower than the upper edge of the first opening 223. This can also be understood as the air duct fixing plate 140 covering the top of the first storage container 200, which has a windproof effect. The sealing part 143 and the outer periphery of the first opening 223 form a relatively sealed state, thereby sealing the first opening 223. This can improve the situation where air inside the first storage container 200 leaks from the left and right sides of the first opening 223 during the refrigeration process.

[0080] Specifically, referring to Figures 8 and 9, the sealing part 143 is arranged on both sides of the air duct fixing plate 140 in the left-right direction and located at the lower edge of the air duct fixing plate 140, so that the sealing part 143 blocks the side of the first storage container 200 in the up-down direction to form a sealing fit. After this arrangement, during the cooling process, the cold air in the first storage container 200 is not easy to flow directly out of the first storage container 200 through the first opening 223, that is, the cold air in the first storage container 200 is not easy to leak out, which can keep the first storage container 200 warm, and the cold air is not easy to flow to the position of the first temperature sensor 500 and affect the temperature detected by the first temperature sensor 500. At the same time, it can also guide the cold air in the first storage container 200 to flow out from the return air part at the rear of the first storage container 200 to the outside of the first storage container 200, achieving the effect of directional return air.

[0081] Referring to FIG8, according to some embodiments of this application, the second storage container 300 is provided with rotatable first rollers 310 on both sides along the left and right directions, and the sealing part 143 is provided with a first guide rail 144. The first guide rail 144 is used to support the first rollers 310. The sealing part 143 can be understood as an L-shaped structure, thereby forming the structure of the first guide rail 144. The bottom of the first rollers 310 abuts against the first guide rail 144. When the user takes out the second storage container 300, the first rollers 310 rotate along the first guide rail 144, which can reduce the movement resistance and facilitate the user to take out the second storage container 300.

[0082] In this embodiment, when the first storage container 200 is in the closed position, the sealing part 143 and the outer periphery of the first opening 223 form a relatively sealed state, thereby sealing the first opening 223. This can improve the situation where air inside the first storage container 200 leaks from the left and right sides of the first opening 223 during the cooling process. When the air humidity in the cooling space 110 is high, it can prevent the position of the first guide rail 144 from becoming too cold due to air leakage, and prevent condensation and frost from forming on the position of the first guide rail 144 due to low temperature. This can also prevent the frost on the first guide rail 144 from rubbing against the first roller 310 during the process of pulling out the second storage container 300, thus improving the user experience.

[0083] Referring to Figure 8, in some embodiments, the first roller 310 is located at the rear end of the second storage container 300, and rotatable second rollers 320 are also provided on the left and right sides of the second storage container 300. The second rollers 320 are located at the front end of the second storage container 300. The inner wall of the first storage container 200 is provided with a second guide rail 224, which is used to support the second rollers 320. The bottom of the second rollers 320 abuts against the second guide rail 224. When the user takes out the second storage container 300, the second rollers 320 rotate along the second guide rail 224, which can reduce the movement resistance and make it convenient for the user to take out the second storage container 300.

[0084] According to some embodiments of this application, the first storage container 200 is provided with a drawer front panel 230, which is located at the front end of the first storage container 200 and extends upward to the front side of the second storage container 300. It can be understood that when viewing the drawer front panel 230 from the perspective of detection, the drawer front panel 230 will block the second storage container 300. In addition, in order to prevent condensation on the drawer front panel 230 due to low temperature, a first insulation layer 231 is provided inside the drawer front panel 230. The first insulation layer 231 is located between the outer wall of the inner cavity 220 and the drawer front panel 230, which can play a heat preservation role. The first insulation layer 231 can be made of foam material.

[0085] When the first storage container 200 and the second storage container 300 are in the closed position, that is, when the first storage container 200 and the second storage container 300 are retracted into the cooling space 110, the drawer front panel 230 can close the opening 111 of the cooling space 110. Compared with the scheme of using the front end of the first storage container 200 to close the lower half of the opening 111 of the cooling space 110, and using the front end of the second storage container 300 to close the upper half of the opening 111 of the cooling space 110, the single drawer front panel 230 of the first storage container 200 can close the entire opening 111 of the cooling space 110, which can reduce the gap between the first storage container 200 and the second storage container 300, improve the sealing performance, and reduce cold air leakage.

[0086] Referring to Figures 4 and 6, according to some embodiments of this application, the side walls on the left and right sides of the second storage container 300 are provided with side air vents 330. During the cooling process, part of the airflow in the second storage container 300 can enter the first storage container 200 through the side air vents 330, as shown by the arrow in Figure 4. The airflow can flow from top to bottom into the second storage container 300, thereby achieving the effect of air distribution. It can deliver air to the top position of the first storage container 200, making the air delivery effect more uniform, effectively improving the temperature uniformity of different positions in the upper and lower storage containers, and ensuring the overall freshness preservation effect of the storage containers.

[0087] Referring to Figures 4 and 6, in some embodiments, there are multiple side air vents 330, which are arranged at intervals along the front-rear direction of the second storage container 300. This can be understood as covering the top of the first storage container 200 in the front-rear direction, which can further improve the uniformity of air supply. The shape of the side air vents 330 can be square, elliptical, circular, or racetrack-shaped.

[0088] Referring to Figure 4, according to some embodiments of this application, the second storage container 300 includes a front wall, which is inclined and has a front air vent 340. During the cooling process, part of the airflow inside the second storage container 300 can enter the first storage container 200 through the front air vent 340, thus supplying air to the front end of the first storage container 200 and further improving the uniformity of airflow. Multiple front air vents 340 can be provided, and these vents are spaced apart along the left-right direction of the second storage container 300. The shape of the front air vent 340 can be square, elliptical, circular, or racetrack-shaped.

[0089] Referring to Figures 10 and 12, according to some embodiments of this application, the first storage container 200 further includes a second insulation layer 250 and an inner cavity 220. The second insulation layer 250 covers the outer wall of the inner cavity 220, and the outer cavity 240 covers the outer wall of the second insulation layer 250. That is, the second insulation layer 250 is located between the outer cavity 240 and the inner cavity 220. The outer cavity 240 is provided with a first clearance hole 241 for avoiding the first temperature sensor 500, and the second insulation layer 250 is provided with a second clearance hole 251 for avoiding the first temperature sensor 500. The second clearance hole 251 is correspondingly provided with the first clearance hole 241. The inner cavity 220 can be understood as the inner layer structure of the first storage container 200, and the outer cavity 240 can be understood as the outer layer structure of the first storage container 200. The outer cavity 240 is connected to the second insulation layer 250 by screws or buckles.

[0090] This embodiment can be understood as employing a sandwich insulation method. When the first storage container 200 is in the closed position, the first temperature sensor 500 extends into the first clearance hole 241 and the second clearance hole 251 to abut against the heat-conducting element 210 inside the inner cavity 220, thereby detecting the temperature. At this time, the second insulation layer 250 surrounds the outer periphery of the first temperature sensor 500, which can isolate the interference of external air to the first temperature sensor 500, making its detection result more accurate. It is understood that the second insulation layer 250 can be made of foam material, which has a good insulation effect.

[0091] Referring to Figures 3, 10, and 11, according to some embodiments of this application, the outer wall of the inner cavity 220 is provided with a positioning part 221. The positioning part 221 is located on the rear side of the inner cavity 220. The second heat-conducting part 212 of the heat-conducting component 210 is embedded between the positioning part 221 and the inner cavity 220. The positioning part 221 is provided with a third clearance hole 222 to avoid the first temperature sensor 500. The positioning part 221 passes through the second clearance hole 251 and can position and install the second insulation layer 250. The positioning part 221 also abuts against the inner wall of the first clearance hole 241, thereby forming a fastening force when assembled with the outer cavity 240 to prevent loosening and play a positioning and anti-loosening role.

[0092] Referring to Figures 3, 10, and 11, in some embodiments, the positioning part 221 and the inner cavity 220 are an integral structure. The positioning part 221 and the inner cavity 220 are made of plastic. The heat-conducting component 210 and the inner cavity 220 are integrally formed by injection molding. It can be understood that the positioning part 221 and the inner cavity 220 constitute a two-layer plastic structure. The heat-conducting component 210 is sandwiched between the positioning part 221 and the inner cavity 220. The positioning part 221 blocks part of the structure of the heat-conducting component 210, thereby limiting the heat-conducting component 210. The positioning part 221 is constructed as a ring structure, thereby forming a third clearance hole 222 at the center of the positioning part 221. The heat-conducting component 210 is exposed to the outside through the third clearance hole 222. The positioning part 221 extends and protrudes towards the rear side of the inner cavity 220, so that the positioning part 221 can cooperate with the second clearance hole 251 of the second insulation layer 250 to play a positioning and installation role. In addition, the positioning part 221 can also abut against the inner wall of the first clearance hole 241 of the outer cavity 240.

[0093] Referring to FIG3, in some other embodiments, when the first storage container 200 is in the closed position, the outer cavity 240 abuts against the seal 121, thereby sealing the gap between the outer cavity 240 and the mounting plate 142, making it difficult for outside air to enter the outer periphery of the first temperature sensor 500.

[0094] Referring to Figures 10 and 12, it can be understood that the second insulation layer 250 and the inner cavity 220 have similar structures, both being box-shaped structures. The heat-conducting element 210 has a sheet-like structure and is located between the second insulation layer 250 and the inner cavity 220. The second insulation layer 250 can wrap around the heat-conducting element 210, providing isolation and preventing the outer cavity 240 or other components from contacting the heat-conducting element 210. Alternatively, it can minimize the contact area between the outer cavity 240 or other components and the heat-conducting element 210, thereby reducing the temperature influence of other structures on the heat-conducting element 210. The heat-conducting element 210 can accurately reflect the temperature of the food, thus improving the accuracy of temperature measurement and control by the first temperature sensor 500.

[0095] In some other embodiments, the positioning part 221 and the inner cavity 220 may also be configured as separate structures, with the positioning part 221 connected to the inner cavity 220 by screws or clips.

[0096] Referring to Figure 5, in some embodiments, the refrigeration device 1000 further includes a second temperature sensor 600. The second temperature sensor 600 is disposed on the air duct fixing plate 140, that is, the second temperature sensor 600 is located at the top of the refrigeration space 110, above the first temperature sensor 500. The second temperature sensor 600 is used to detect the temperature of the air in the refrigeration space 110. Compared with the first temperature sensor 500, during the refrigeration process, the cold air will directly pass through the second temperature sensor 600. The first temperature sensor 500 is mainly used to detect the temperature of the food in the first storage container 200. The cold air does not directly pass through the first temperature sensor 500, and the temperature of the food changes more slowly. When the user puts in new food, the temperature of the food is inconsistent with the temperature of the refrigeration space 110. The temperature of the second temperature sensor 600 changes more quickly and is more sensitive, which can be used to achieve temperature control. The air duct structure 400 is equipped with a damper mechanism, which includes a first damper and a second damper. The first damper controls the opening or closing of the air supply duct 410, thereby controlling whether the air supply duct 410 supplies air to the refrigerator compartment 150. The second damper controls the opening or closing of the refrigerator compartment 420, thereby controlling whether the refrigerator compartment 420 supplies air to the refrigeration space 110. The refrigeration equipment 1000 also includes a controller, which can control the operation of the damper mechanism based on the sensing signals from the first temperature sensor 500 and the second temperature sensor 600. Specific control actions can be found in the following embodiment.

[0097] Referring to FIG13, some embodiments of this application also provide a control method for controlling the refrigeration equipment of the above embodiments. The control method includes steps S100 and S200. The control method mainly controls the operation of the damper mechanism based on the temperature detected by the first temperature sensor and the second temperature sensor.

[0098] Step S100: Obtain a first signal and control the temperature of the cooling space according to a first preset temperature, wherein the first signal indicates that the temperature control function has been activated and the cabinet door has been closed.

[0099] Step S200: Obtain a second signal and control the temperature of the cooling space according to a second preset temperature. The second signal is characterized by the first temperature sensor detecting a value that is continuously greater than the target temperature for a first preset time period, the first preset temperature being less than or equal to the target temperature and greater than the second preset temperature.

[0100] In this step, if the value detected by the first temperature sensor remains higher than the target temperature for a first preset time period, it indicates that the temperature at the bottom of the food cannot reach the target temperature for a long time. This suggests that the food was recently added by the user, is hot, or is in large quantities. To ensure preservation, rapid cooling is necessary. At this time, the temperature of the cooling space is controlled according to the second preset temperature. When the temperature value detected by the second temperature sensor is higher than the second preset temperature, the first damper is opened, allowing airflow to the cooling space and increasing the air volume. When the temperature value detected by the second temperature sensor is lower than or equal to the second preset temperature, the first damper is closed, reducing the air volume and maintaining the temperature of the cooling space at the second preset temperature. The second preset temperature is lower than the first preset temperature, and the cooling space cools the food in the first storage container at a lower temperature, which is beneficial for rapid cooling and improving preservation. When the value detected by the first temperature sensor is lower than or equal to the target temperature, it indicates that the food temperature is too low, and it can be determined that the food has frozen. At this time, the temperature of the cooling space can be switched to the first preset temperature. Since the first preset temperature is relatively higher than the second preset temperature, over-freezing of the food can be avoided.

[0101] In some embodiments, when the cooling space is set as a variable temperature compartment, the first preset duration can be any time value within the range of 0.5h to 1h, the target temperature can be set to -0.5℃, and the second preset temperature can be set to -4℃ to -2℃. This can also be understood as the temperature control function maintaining the cooling space within the temperature range of -4℃ to -2℃ by controlling the opening or closing of the first air damper. When the cooling space is set as a freezer or refrigerator compartment, the target temperature and the second preset temperature can be set to other temperature values.

[0102] Referring to FIG14, according to some embodiments of this application, the above-described control method further includes steps S300, S400 and S500.

[0103] Step S300: Obtain the cumulative duration of temperature control according to the second preset temperature;

[0104] Step S400: When the cumulative duration is less than the second preset duration, the temperature is controlled according to the first preset temperature;

[0105] Step S500: When the cumulative duration is greater than or equal to the second preset duration, the temperature is controlled according to the second preset temperature.

[0106] In this embodiment, during the temperature control process according to the second preset temperature, the refrigeration equipment determines the amount of food stored in the first storage container based on the cumulative time it takes for the refrigeration space to reach the second preset temperature. This determines whether to continue temperature control according to the second preset temperature or the first preset temperature. This can be understood as controlling the temperature of the refrigeration space based on the amount of food stored in the first storage container, which is beneficial for food preservation. If there is a large amount of food, maintaining a lower second preset temperature accelerates cooling and prevents localized areas from failing to reach the expected temperature. If there is a small amount of food, using a higher first preset temperature saves energy, improves energy efficiency, and also prevents some types of food from freezing.

[0107] In some embodiments, when the refrigeration space is set as a variable temperature compartment, the second preset duration can be set to 12 hours. When the refrigeration space is set as a freezer or refrigerator compartment, the second preset duration can be set to other time values.

[0108] Referring to Figure 15, which is a flowchart of a control method according to some embodiments of this application, the process begins by determining whether the cabinet door is closed. If the door is closed, the temperature control steps proceed. After the door is closed, a second temperature sensor detects the temperature of the cooling space. The second temperature sensor controls the temperature of the cooling space between -2.5°C and -0.5°C. When the temperature value of the second temperature sensor is below -2.5°C, the first damper is closed to reduce the airflow to the cooling space and prevent the food inside from overfreezing. When the temperature value of the second temperature sensor is higher than or equal to -0.5°C, the first damper is opened to increase the airflow to the cooling space and prevent the food inside from overfreezing. Then, the first temperature sensor starts detecting the temperature and determines whether the temperature value of the first temperature sensor remains above -0.5°C for 0.5 hours to 1 hour. If so, the second temperature sensor controls the temperature of the cooling space between -4°C and -2°C until the temperature value of the first temperature sensor remains below -4°C for 0.5 hours to 1 hour. If the temperature is -0.5℃ or higher, it indicates that the food in the refrigeration space is frozen or the food load is low. Then, the cumulative time for the second temperature sensor to control the temperature of the refrigeration space at -4℃ to -2℃ is recorded, and it is determined whether the cumulative time is greater than or equal to 12 hours. If so, it indicates that the food load exceeds half the capacity of the storage container, meaning the food load is large. In this case, the second temperature sensor is maintained at -4℃ to -2℃ to control the temperature of the refrigeration space, using a lower temperature to accelerate cooling and prevent local areas of food from not reaching the expected temperature. If not, it indicates that the food load is less than half the capacity of the storage container, meaning the food load is low. In this case, the second temperature sensor is maintained at -2.5℃ to -0.5℃ to control the temperature of the refrigeration space, using a higher temperature to control the temperature, which saves more energy, improves energy efficiency, and also prevents some types of food from freezing.

[0109] In some embodiments, the refrigeration device 1000 can be configured as a dual-system refrigerator, having two independent refrigeration systems, specifically a first refrigeration system and a second refrigeration system. A first evaporator is the refrigeration element in the first refrigeration system, which provides cooling to the refrigerator compartment 150 and the variable temperature compartment via the first evaporator. The second refrigeration system includes a second evaporator, which provides cooling to the freezer compartment via the second evaporator. Because the two refrigeration systems are independent, the dual-system refrigerator has better odor prevention and refrigeration / humidification effects. In other embodiments, the refrigeration device 1000 can also be configured as a single-system refrigerator, having only one refrigeration system. The first evaporator is the refrigeration element in this system, which provides cooling to the refrigerator compartment 150, the variable temperature compartment, and the freezer compartment via the first evaporator.
