Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and particularly to refrigeration equipment, control methods, control devices, and storage media. Background Technology

[0002] Currently, most refrigeration equipment uses air cooling to achieve its cooling effect. Cold air flows into the refrigeration space through air ducts to preserve the food inside. In these technologies, the amount of cold air entering the refrigeration space is fixed. If the air volume is too small, the temperature of the food in the refrigeration space will remain too high, thus shortening its shelf life. If the air volume is too large, the food in the refrigeration space will overfreeze, affecting its quality. Therefore, it is difficult to balance the air volume. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a refrigeration device that can control the ventilation area of ​​the damper mechanism according to the temperature value of a first temperature sensor, thereby adjusting the air volume supplied by the air supply channel to the refrigerated space.

[0004] A refrigeration device according to a first aspect of the present invention includes: a housing having a refrigeration space; a first storage container disposed within the refrigeration space; an air duct assembly disposed in the housing, the air duct assembly including a damper mechanism and an air supply channel communicating with the refrigeration space, the damper mechanism being used to control the opening or closing of the air supply channel; a first temperature sensor disposed at the bottom of the first storage container; and a controller controlling the operation of the damper mechanism according to a transmission signal from the first temperature sensor; wherein the damper mechanism has a first state and a second state, in the first state the ventilation area of ​​the damper mechanism is S1, and in the second state the ventilation area of ​​the damper mechanism is S2, satisfying 0 < S1 < S2.

[0005] The refrigeration device according to embodiments of the present invention has at least the following beneficial effects: when the refrigeration device is refrigerating, cold air enters the refrigeration space through the air supply channel, thereby preserving the food in the first storage container. The first temperature sensor can detect the temperature of the first storage container in real time. The controller can adjust the air intake area of ​​the damper mechanism according to the temperature detected by the first temperature sensor, thereby adjusting the air intake volume of the damper mechanism. Specifically, the damper mechanism has a first state and a second state. The ventilation area of ​​the damper mechanism in the first state is smaller than that in the second state. That is, in the first state, the air supply volume of the air supply channel is smaller, and in the second state, the air supply volume of the air supply channel is larger. Thus, the damper mechanism can be switched between the first state and the second state according to the temperature detected by the first temperature sensor, thereby achieving a ratio between the temperature of the first storage container and the air supply volume, which can improve the preservation effect of the food.

[0034] Reference Figure 1As shown, the refrigeration device 1000 provided by the present invention includes a housing 100, a first storage container 200, an air duct assembly 400, a first temperature sensor 210, and a controller. The refrigeration device 1000 can be configured as a refrigerator or freezer. The interior of the cabinet 100 includes a refrigeration space 110. A first storage container 200 is disposed within the refrigeration space 110. An air duct assembly 400 is disposed within the cabinet 100. The air duct assembly 400 is primarily used to circulate air within the refrigeration space 110. The air duct assembly 400 includes a damper mechanism 410 and an air supply channel 420. The air supply channel 420 is connected to the refrigeration space 110. The damper mechanism 410 can control the opening and closing of the air supply channel 420. A first temperature sensor 210 is disposed at the bottom of the first storage container 200. The first temperature sensor 210 can detect the temperature of the first storage container 200. Since the first temperature sensor 210 is relatively close to the food inside the first storage container 200, the temperature detected by the first temperature sensor 210 can be understood as the temperature of the bottom of the food inside the first storage container 200, resulting in a relatively accurate detection result. The controller is configured to control the action of the damper mechanism 410 based on the transmission signal from the first temperature sensor 210.

[0035] The refrigeration device 1000 in this embodiment uses air cooling to achieve refrigeration. The refrigeration device 1000 also includes a first evaporator 130 and a fan 140. The first evaporator 130 and the fan 140 are arranged within the air duct assembly 400. When the fan 140 rotates, it generates airflow. This airflow transfers the cooling energy generated by the first evaporator 130 to the refrigeration space 110 through the air supply channel 420, thereby achieving a refrigeration effect and preserving the food within the refrigeration space 110. The airflow direction can be referenced... Figures 1 to 15 The direction of the dashed arrow in the image.

[0036] Specifically, the damper mechanism 410 has a first state and a second state. When the refrigeration equipment 1000 is operating in the first mode, the damper mechanism 410 is in the second state; when the refrigeration equipment 1000 is operating in the second mode, the damper mechanism 410 is in the first state. When the damper mechanism 410 is in the first state, the ventilation area of ​​the damper mechanism 410 is S1, where S1 is greater than 0. That is, the damper mechanism 410 is in the open state, thereby opening the air supply channel 420 and delivering cold air to the refrigeration space 110. When the damper mechanism 410 is in the second state, the ventilation area of ​​the damper mechanism 410 is S2, which is greater than 0. At this time, the damper mechanism 410 is in the open state, thereby opening the air supply channel 420 and delivering cold air to the cooling space 110. Here, S2 is greater than S1, that is, the ventilation area of ​​the damper mechanism 410 in the second state is greater than the ventilation area of ​​the damper mechanism 410 in the first state. When the damper mechanism 410 is in the second state, the air supply channel 420 delivers a larger amount of air to the cooling space 110. When the damper mechanism 410 is in the first state, the air supply channel 420 delivers a smaller amount of air to the cooling space 110.

[0037] When the refrigeration equipment 1000 is refrigerating, cold air enters the refrigeration space 110 through the air supply channel 420, thereby preserving the food in the first storage container 200. The first temperature sensor 210 can detect the temperature of the first storage container 200 in real time. The controller can adjust the ventilation area of ​​the damper mechanism 410 according to the temperature detected by the first temperature sensor 210, thereby adjusting the air intake of the air supply channel 420. Specifically, the controller can control the damper mechanism 410 to switch between the first state and the second state to achieve the ratio of temperature and air supply of the first storage container 200, which can improve the preservation effect of the food.

[0038] Specifically, when the temperature detected by the first temperature sensor 210 is low, it indicates that the food in the first storage container 200 has frozen. At this time, the damper mechanism 410 can be controlled to switch to the first state, reducing the airflow from the air supply channel 420 to the cooling space 110 to prevent the food in the first storage container 200 from overfreezing. When the temperature detected by the first temperature sensor 210 is high, it indicates that the user has just placed the food in the first storage container 200 or the food load is large. At this time, the damper mechanism 410 can be controlled to switch to the second state, thereby increasing the airflow from the air supply channel 420 to the cooling space 110, ensuring that the temperature in the cooling space 110 is low and the food preservation effect is better.

[0039] To accurately control the ventilation volume of the damper mechanism based on the temperature of the food ingredients, refer to Figure 16 As shown, this embodiment also provides a control method for a refrigeration device, wherein the control method includes steps S100 and S200, as detailed below.

[0040] Step S100: Obtain a first signal and control the refrigeration equipment to work in a first mode. The first signal is characterized by the first temperature sensor detecting a value that is continuously less than or equal to a preset temperature value within a preset time period. In the first mode, the ventilation area of ​​the damper mechanism is S1, which satisfies 0 < S1.

[0041] In this step, when the temperature value detected by the first temperature sensor 210 is less than or equal to the preset temperature value and the duration exceeds the preset duration, the first temperature sensor 210 sends a first signal to the controller, indicating that the temperature of the food in the first storage container 200 is too low or the food load in the first storage container 200 is too small. In order to avoid overfreezing, the refrigeration equipment 1000 can be controlled to work in the first mode, thereby controlling the damper mechanism 410 to switch to the first state, reducing the air volume of the air supply channel 420, and less cold air is sent into the refrigeration space 110, which can prevent the food in the first storage container 200 from overfreezing, thereby improving the preservation effect.

[0042] Step S200: Obtain a second signal and control the refrigeration equipment to work in a second mode. The second signal is characterized by the first temperature sensor detecting a value that is continuously greater than a preset temperature value within a preset time period. In the second mode, the ventilation area of ​​the damper mechanism is S2, which satisfies S1 < S2.

[0043] In this step, when the temperature value detected by the first temperature sensor 210 is less than or equal to the preset temperature value and the duration exceeds the preset duration, the first temperature sensor 210 sends a first signal to the controller, indicating that the temperature of the food in the first storage container 200 is too low or the food load in the first storage container 200 is too small. In order to avoid overfreezing, the refrigeration equipment 1000 can be controlled to work in the first mode, thereby controlling the damper mechanism 410 to switch to the first state, reducing the air volume of the air supply channel 420, and less cold air is sent into the refrigeration space 110, which can prevent the food in the first storage container 200 from overfreezing, thereby improving the preservation effect.

[0044] In the above embodiments, the preset duration can be set to any time value within the range of 0.5 hours to 1 hour, and the preset temperature value is -0.5℃. For example, if the preset duration is set to 0.5 hours, when the temperature value detected by the first temperature sensor 210 is less than or equal to -0.5℃ and remains so for 0.5 hours, the first temperature sensor 210 sends a first signal to the controller. In other embodiments, the preset duration and preset temperature value can also be set to other values.

[0045] Reference Figure 1As shown, 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. The cabinet 100 also includes a refrigerator compartment 120, located above the variable temperature compartment. The refrigerator compartment 120 is equipped with shelves 600 for placing items. (Ref.) Figure 2 As shown, the air duct assembly 400 also includes a refrigerated damper 430 and a refrigerated passage 440. The refrigerated passage 440 is connected to the refrigerator compartment 120 and is also connected to the air supply passage 420. The airflow generated by the fan 140 is diverted to the refrigerated passage 440 and the air supply passage 420. The refrigerated damper 430 is used to control the opening or closing of the refrigerated passage 440, thereby controlling whether the refrigerated passage 440 supplies air to the refrigerator compartment 120.

[0046] In this embodiment, by arranging the damper mechanism 410 and the refrigeration damper 430 to form two damper structures, the air supply volume of the variable temperature compartment and the refrigeration compartment 120 can be controlled separately. The refrigeration equipment 1000 can automatically adjust the closing of the two dampers according to the food load and freezing status, thereby adjusting the air volume ratio of the refrigeration compartment 120 and the ice-temperature preservation drawer. Specifically, when the first temperature sensor 210 detects a high temperature in the ice-temperature preservation drawer, it indicates that the food load is large, or that the user has just placed food into the ice-temperature preservation drawer. At this time, the cooling demand of the ice-temperature preservation drawer is greater than the cooling demand of the refrigerator compartment 120. The refrigerator damper 430 can be closed, allowing all the airflow generated by the fan 140 to flow into the air supply channel 420, thereby increasing the airflow volume of the air supply channel 420 to the ice-temperature preservation drawer and ensuring the preservation effect of the ice-temperature preservation drawer. When the first temperature sensor 210 detects a low temperature in the ice-temperature preservation drawer, it indicates that the food load is small. At this time, the cooling demand of the ice-temperature preservation drawer is less than the cooling demand of the refrigerator compartment 120. The refrigerator damper 430 can be opened, allowing a portion of the airflow generated by the fan 140 to flow into the refrigerator channel 440, thereby supplying air to the refrigerator compartment 120 and improving the cooling effect of the refrigerator compartment 120.

[0047] It should be noted that the refrigerator compartment 120 and the variable temperature compartment are two independent chambers. The refrigerator compartment 120 is not directly connected to the variable temperature compartment, which reduces the temperature influence between the two. (Ref.) Figure 2 As shown, the bottom of the air duct assembly 400 is provided with multiple return air vents 450. Some of the return air vents 450 are used to allow air in the refrigerator compartment 120 to flow back into the air duct assembly 400, while the other part of the return air vents 450 are used to allow air in the refrigeration space 110 to flow back into the air duct assembly 400.

[0048] In some other embodiments, the refrigeration space 110 described above can also be configured as a refrigerator compartment 120 or a freezer compartment. 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 120 is generally above 2°C.

[0049] Reference Figure 3 As shown, in some embodiments, the damper mechanism 410 is a single damper structure. The single damper structure is rotatable, and the rotation angle of the single damper structure is related to the air supply volume of the air supply channel 420. When the single damper structure is in the initial position, the single damper structure fully opens the air supply channel 420. When the single damper structure starts to rotate from the initial position, as the rotation angle of the single damper structure increases, the air supply volume of the air supply channel 420 gradually decreases, that is, the damper structure gradually closes the air supply channel 420. The rotation angle of the single damper structure can also be understood as the closing angle. The controller can control the air volume of the air supply channel 420 by controlling the closing angle of the single damper structure.

[0050] In this embodiment, the damper mechanism 410 is provided with a single damper structure. When the damper mechanism 410 is in the first state, the damper mechanism 410 rotates 30° to 60° relative to the initial position, and the air supply volume is small. When the damper mechanism 410 is in the second state, the damper mechanism 410 rotates 90° relative to the initial position, that is, the damper mechanism 410 is in the fully open state, and the air supply volume is the maximum.

[0051] When the damper mechanism 410 is configured as a single damper structure, the above control method can be refined. Specifically, in step S100, the refrigeration equipment 1000 is controlled to operate in the first mode, which specifically includes step S110. In step S200, the refrigeration equipment 1000 is controlled to operate in the second mode, which specifically includes step S210.

[0052] Step S110: Control the damper mechanism to open to the first angle.

[0053] Step S210: Control the damper mechanism to open to a second angle, which is greater than the first angle.

[0054] In this embodiment, the damper mechanism 410 is a single damper structure. The opening and closing angle of the damper mechanism 410 is controlled to control the air supply channel 420 to output different air volumes to the variable temperature chamber.

[0055] Reference Figure 4As shown, in some embodiments, the damper mechanism 410 includes a first damper 411 and a second damper 412, that is, the damper mechanism 410 is configured as a double damper structure, and the air supply channel 420 is a single air duct structure. When the damper mechanism 410 is in the first state, the first damper 411 is open and the second damper 412 is closed; when the damper mechanism 410 is in the second state, both the first damper 411 and the second damper 412 are open. In this embodiment, by configuring the damper mechanism 410 as a double damper structure, the controller can control the opening and closing of the first damper 411 and the second damper 412, thereby enabling the air supply channel 420 to deliver different air volumes to the first storage container 200.

[0056] When the damper mechanism 410 is configured as a double damper structure, that is, the damper mechanism 410 includes a first damper 411 and a second damper 412, the above control method can be refined. Specifically, in step S100, the refrigeration device 1000 is controlled to operate in the first mode, which specifically includes step S120. In step S200, the refrigeration device 1000 is controlled to operate in the second mode, which specifically includes step S220.

[0057] Step S120: Control the first damper to open and control the second damper to close.

[0058] Step S220: Control both the first and second air dampers to open.

[0059] In this embodiment, the damper mechanism 410 is a double damper structure. The two dampers of the damper mechanism 410 are controlled to open and close, thereby achieving different air supply volumes for the variable temperature chamber.

[0060] In some embodiments, refer to Figure 4 As shown, a second temperature sensor 111 is provided at the top of the cooling space 110. The second temperature sensor 111 is located above the first storage container 200. The second temperature sensor 111 is used to monitor the air temperature inside the cooling space 110. The cold air flowing out from the air supply channel 420 passes directly through the second temperature sensor 111. The second temperature sensor 111 can be used to quickly control the temperature of the cooling space 110. For example, when the first storage container 200 has a cooling demand, the air supply volume of the damper structure is increased. By monitoring the temperature through the second temperature sensor 111, the temperature of the cooling space 110 is kept at a low level, which can quickly cool the food in the first storage container 200.

[0061] Therefore, such as Figure 17 As shown, this embodiment also provides a control method for a refrigeration device. The control method specifically includes steps S300 and S400, as detailed below.

[0062] Step S300: Obtain a second signal, which indicates that the value detected by the first temperature sensor is continuously greater than or equal to a preset temperature value within a preset time period. When the value detected by the second temperature sensor is greater than the maximum value of the first target temperature range, control the damper mechanism to open. When the value detected by the second temperature sensor is less than the minimum value of the first target temperature range, control the damper mechanism to close.

[0063] In this step, when the temperature value detected by the first temperature sensor 210 is continuously greater than the preset temperature value within a preset time period, the first temperature sensor 210 will send a second signal to the controller. This indicates that the temperature inside the first storage container 200 is high, and it can be determined that the food load inside the first storage container 200 is large or that the user has just put the food into the first storage container 200, and the first storage container 200 has a strong cooling demand. If the temperature value detected by the second temperature sensor 111 is greater than the maximum value of the first target temperature range, it indicates that the temperature inside the cooling space 110 is high and the cooling rate is slow. In this case, the damper mechanism 410 can be fully opened to deliver cold air to the cooling space 110 at maximum capacity, allowing the cooling space 110 to cool down quickly. If the temperature value detected by the second temperature sensor 111 is less than the minimum value of the first target temperature range, it indicates that the temperature inside the cooling space 110 is already at a low level. In this case, the damper mechanism 410 can be closed to stop delivering cold air to the cooling space 110, preventing the food from overfreezing. In addition, the airflow from the refrigeration duct to the refrigerator compartment 120 can be increased. This can be understood as follows: when the first storage container 200 has a strong cooling demand, the temperature of the cooling space 110 is controlled within the first target temperature range. Since the temperature in the first target temperature range is relatively low, the temperature of the cooling space 110 can be quickly lowered, increasing the cooling rate.

[0064] Step S400: Obtain a first signal, which is characterized by the first temperature sensor detecting a value that is continuously less than or equal to a preset temperature value within a preset time period. When the second temperature sensor detects a value that is greater than the maximum value of the second target temperature range, control the damper mechanism to open. When the second temperature sensor detects a value that is less than the minimum value of the second target temperature range, control the damper mechanism to close. The maximum value of the first target temperature range is less than the minimum value of the second target temperature range.

[0065] In this step, when the temperature value detected by the first temperature sensor 210 remains below or equal to the preset temperature value for a preset duration, the first temperature sensor 210 sends a first signal to the controller, indicating that the temperature inside the first storage container 200 is low. This indicates that the food inside the first storage container 200 is frozen or that the food load inside the first storage container 200 is low, and the first storage container 200 has a weak cooling demand. If the temperature value detected by the second temperature sensor 111 is less than the maximum value of the second target temperature range, it indicates that the temperature inside the cooling space 110 is low. To prevent the food from overfreezing, the damper mechanism 410 can be closed to stop supplying cold air to the cooling space 110. If the temperature value detected by the second temperature sensor 111 is greater than the maximum value of the second target temperature range, it indicates that the temperature inside the cooling space 110 is high and does not meet the maximum temperature limit of the cooling space 110. In this case, the damper mechanism 410 can be opened to supply cold air to the cooling space 110 to cool it down. This can be understood as follows: when the first storage container 200 has a weak cooling demand, the temperature of the cooling space 110 is controlled within the range of the second target temperature range. Since the temperature of the second target temperature range is relatively higher than that of the first target temperature range, the temperature of the first storage container 200 can be quickly raised to avoid the food in the first storage container 200 from overfreezing.

[0066] In the above embodiments, for example, the minimum value of the first target temperature range is -6℃, the maximum value of the first target temperature range is -4℃, and the length of the first target temperature range is 2℃. The minimum value of the second target temperature range is -3℃, the maximum value of the second target temperature range is -1℃, and the length of the second target temperature range is 2℃. In other embodiments, the maximum and minimum values ​​of the above-mentioned target temperature ranges can also be set to other temperature values.

[0067] Reference Figure 19 The diagram shows the flow of the control method provided in this embodiment. This control flow is mainly aimed at controlling... Figure 3The refrigeration equipment in the middle is 1000. Initially, the system checks whether the refrigeration damper 430 is closed to determine if the refrigerator compartment 120 requires cooling. When the damper 430 is open, it indicates that the refrigerator compartment 120 is requesting cooling; when it is closed, it indicates that the refrigerator compartment 120 is not currently requesting cooling. The cooling process for the variable temperature compartment proceeds only after the damper 430 closes. This can be understood as separating the cooling processes for the refrigerator compartment 120 and the variable temperature compartment to ensure sufficient airflow to the variable temperature compartment. Next, the damper mechanism 410 is opened 30-60°. At this point, the ventilation area of ​​the damper mechanism 410 is relatively small, resulting in a smaller airflow to the variable temperature compartment through the air supply channel 420. Then, temperature control is achieved using the temperature detected by the second temperature sensor 111. When the temperature value of the second temperature sensor 111 is below -3°C, the damper mechanism 410 is closed; when the temperature value of the second temperature sensor 111 is above -1°C, the damper mechanism 410 is opened. This is primarily to maintain the temperature of the variable temperature compartment. The temperature is maintained at -3°C to -1°C for temperature control, which can be understood as step S300 in the above embodiment. Then, it is determined whether the temperature value detected by the first temperature sensor 210 is higher than -0.5°C and lasts for 0.5h to 1h. If so, the damper mechanism 410 is fully opened to 90°, and the air supply channel 420 supplies air to the variable temperature compartment at the maximum air volume, which can quickly reduce the temperature of the variable temperature compartment. The variable temperature compartment cools the food in the first storage container 200 at a lower ambient temperature, achieving a rapid cooling effect. This step can be understood as step S400 in the above embodiment. The damper mechanism 410 is fully opened to 90° until the temperature value detected by the first temperature sensor 210 is lower than or equal to -0.5°C and lasts for 0.5h to 1h. Then it is determined that the food in the first storage container 200 has frozen or the food load is small. At this time, the process returns to the step of controlling the damper mechanism 410 to open to 30 to 60°, and the temperature of the variable temperature compartment is controlled at -3°C to -1°C to avoid overfreezing of the food. This process is repeated in a loop. Figure 3 These steps form a cyclic refrigeration process.

[0068] Reference Figure 20 The diagram shows the flow of the control method provided in this embodiment. This control flow is mainly aimed at controlling... Figure 4 The refrigeration equipment 1000 is located within this system. This control process primarily targets the control of... Figure 4 The refrigeration equipment in the middle is 1000. Figure 20 The control process in the main body is related to Figure 19 The control flow is similar to that in other systems, so it will not be described in detail here. Figure 20 The control process is mainly aimed at controlling refrigeration equipment 1000 with a single drawer and double damper structure. Figure 19 The control process mainly targets the control of refrigeration equipment 1000 with a single drawer and single damper structure. Figure 19Based on the control process, Figure 19 The step of "opening damper mechanism 410 30-60°" should be changed to "closing the first damper 411 or the second damper 412", and the step of "fully opening damper mechanism 410 90°" should be changed to "opening the first damper 411 and the second damper 412". Figure 20 The control process will not be elaborated here.

[0069] Reference Figure 5 As shown, in some embodiments, the damper mechanism 410 includes a first damper 411 and a second damper 412, and the air supply channel 420 includes a first air duct 421 and a second air duct 422 that are independent of each other. The first air duct 421 and the second air duct 422 can divert the airflow in the air supply channel 420. The first damper 411 is disposed in the first air duct 421 and is used to control the opening or closing of the first air duct 421. The second damper 412 is disposed in the second air duct 422 and is used to control the opening or closing of the second air duct 422. The refrigeration equipment 1000 also includes a second storage container 300, which is arranged in the refrigeration space 110. In this embodiment, the damper mechanism 410 is set as a double damper structure and the air supply channel 420 is set as a double air duct structure. The first air duct 421 and the second air duct 422 have multiple configuration methods, thereby realizing flexible adjustment of the air volume ratio of the first storage container 200 and the second storage container 300 to achieve different refrigeration effects. The following embodiments will illustrate each one.

[0070] Reference Figure 5 and Figure 6As shown, in some embodiments, the second storage container 300 is located below the first storage container 200, and the first storage container 200 is located inside the second storage container 300. Both the first and second storage containers are configured as drawers, thus forming a layered drawer structure. When taking out food from or placing food into the first storage container 200, the second storage container 300 must be pulled out first to reveal the first storage container 200, and then the first storage container 200 can be pulled out. Furthermore, the first and second storage containers 200 are open drawer structures, and the inner cavities of the first and second storage containers 300 are connected, allowing cold air to flow between the inner cavities of the first and second storage containers 300. The first air duct 421 and the second air duct 422 are located at the rear of the cooling space 110. The first air duct 421 only supplies air to the first storage container 200. The cold air in the first air duct 421 flows into the interior of the first storage container 200 from the rear to the front. Part of the structure of the second air duct 422 extends to the bottom of the first air duct 421. The second air duct 422 only supplies air to the second storage container 300. The cold air in the second air duct 422 flows into the interior of the second storage container 300 from the rear to the front.

[0071] In this embodiment, by arranging the first air duct 421 to supply air only to the first storage container 200 and the second air duct 422 to supply air only to the second storage container 300, the air supply volume to the first storage container 200 and the second storage container 300 can be accurately controlled by controlling the opening and closing of the first air damper 411 or the second air damper 412. This allows for the matching of air volume between the first storage container 200 and the second storage container 300. The first air duct 421 and the second air duct 422 supply air to the first storage container 200 and the second storage container 300 separately, making the air volume matching control relatively simple.

[0072] In some other embodiments, the first storage container 200 and the second storage container 300 may be located at the same height, or the first storage container 200 may be located below the second storage container 300, and the second storage container 300 may be located inside the first storage container 200. When taking out food from the second storage container 300 or putting food into the second storage container 300, the first storage container 200 must be pulled out first before the second storage container 300 can be exposed, and then the second storage container 300 can be pulled out.

[0073] Reference Figures 7 to 9As shown, in some embodiments, the first storage container 200 is located above the second storage container 300. Both the first air duct 421 and the second air duct 422 are located above the first storage container 200. The first air duct 421 has a first air outlet 4211, which faces downwards and is directed towards the first storage container 200, supplying air only to the first storage container 200. The second air duct 422 has a second air outlet 4212, which is located at the front end of the second air duct 422, faces downwards, and is directed towards the second storage container 300, supplying air only to the second storage container 300. The first storage container 200 is provided with an air guide section, which is specifically configured as an air guide channel 500. The air guide channel 500 connects the second air outlet 4212 and the second storage container 300. The air guide channel 500 can guide the cold air flow from the second air outlet 4212 into the interior of the second storage container 300, thereby playing the role of air guide.

[0074] In this embodiment, both the first air duct 421 and the second air duct 422 are arranged above the first storage container 200. The first air duct 421 and the second air duct 422 are located at the same horizontal position, compared to Figure 6 In this embodiment, the height occupied by the first air duct 421 and the second air duct 422 is reduced, which can reduce the space occupied and increase the storage capacity of the first storage container 200 and the second storage container 300. In addition, the second temperature sensor 111 is arranged above the first storage container 200. The cold air flow in the first air duct 421 and the second air duct 422 will pass through the second temperature sensor 111, which is conducive to the second temperature sensor 111 quickly detecting the temperature and making the temperature control response more sensitive.

[0075] In some other embodiments, the air guide may be formed on the second storage container 300, or both the first storage container 200 and the second storage container 300 may be provided with air guides, or the air guide may be defined between the first storage container 200 and the second storage container 300.

[0076] Reference Figure 8 and Figure 9 As shown, there are multiple first air outlets 4211, which are arranged at intervals along the front-to-back direction of the refrigeration device 1000. During the refrigeration process, this allows cold air to be evenly blown onto the food in the first storage container 200, preventing localized overfreezing and ensuring a more uniform refrigeration effect. The second air outlet 4212 is located above and in front of the first storage container 200, preventing the first storage container 200 from obstructing the second air outlet 4212. The first and second air outlets 4211 and 4212 can be shaped like squares, circles, ovals, or oblong shapes.

[0077] Reference Figure 9 As shown, Figure 9 The second air duct 422 is viewed from a top-down angle. The second air duct 422 is L-shaped, that is, the second air duct 422 includes a first air duct and a second air duct. The first air duct extends in the front-back direction, and the second air duct is perpendicular to the first air duct. The second air duct is located at the front end of the second air duct. The second air outlet 4212 is arranged in the position of the second air duct, so that the second air outlet 4212 can extend fully along the length of the second air duct to expand the air outlet area of ​​the second air outlet 4212 and increase the air volume supplied by the second air duct 422 to the second storage container 300.

[0078] In some embodiments, a control method is also provided, the control method including step S500. The control method can be used to control... Figure 6 or Figure 8 The refrigeration equipment in the middle is 1000, of which, Figure 6 Implementation examples and Figure 8 The embodiments all have a common feature: the first air duct 421 of both only supplies air to the first storage container 200, and the second air duct 422 of both only supplies air to the second storage container 300.

[0079] Step S500: Acquire the second signal and the third signal, control the first damper to remain open, and control the second damper to open for a second time at a first time interval. The second signal indicates that the value detected by the first temperature sensor is continuously greater than the preset temperature value within the preset time interval, and the third signal indicates that the value detected by the third temperature sensor is continuously less than or equal to the preset temperature value within the preset time interval.

[0080] In this step, when the controller receives the second and third signals, it indicates that the first storage container 200 has a strong cooling demand, while the second storage container 300 has a weak cooling demand. At this time, the first damper 411 is kept open, and the first damper 411 can supply air to the first storage container 200 at maximum capacity to quickly cool the food in the first storage container 200 and improve the cooling rate. At the same time, in order to maintain the temperature of the second storage container 300, the second damper 412 is opened for a second time at a first time interval, that is, the second air duct 422 intermittently supplies air to the second storage container 300. This ensures that the temperature of the food in the second storage container 300 is neither too high nor too low. In addition, when the second damper 412 is closed, the air supply volume of the first air duct 421 will increase accordingly, which is beneficial to cooling the first storage container 200. In this embodiment, the positions of the first storage container 200 and the second storage container 300 are not limited. The first storage container 200 can be located above or below the first storage container 300.

[0081] In some other embodiments, when the first signal and the fourth signal are acquired, the first signal indicates that the value detected by the first temperature sensor 210 is continuously less than or equal to the preset temperature value within a preset time period, and the fourth signal indicates that the value detected by the third temperature sensor 310 is continuously higher than the preset temperature value within a preset time period. This indicates that the second storage container 300 has a strong cooling demand, while the cooling demand of the first storage container 200 is weak. At this time, the second damper 412 can be controlled to remain open. The second damper 412 can deliver air to the second storage container 300 at maximum capacity to quickly cool down the food in the second storage container 300 and improve the cooling rate. At the same time, in order to maintain the temperature of the first storage container 200, the first damper 411 is controlled to open for a second time period every first time period, that is, the first air duct 421 intermittently delivers air to the second storage container 300. In addition, during the process of closing the first damper 411, the air volume delivered by the second air duct 422 will increase accordingly, which is beneficial to cooling the first storage container 200.

[0082] In some embodiments, any time value within a time interval of 10 min to 20 min can be selected as the first duration described above, and any time value within a time interval of 5 min to 10 min can be selected as the second duration described above. The first duration can be longer than the second duration, that is, during the intermittent opening and closing of the damper, the closing time of the damper is longer than the opening time of the damper. This is beneficial for maintaining the temperature of the corresponding storage container and also for increasing the air volume of the air duct corresponding to the other damper for a longer period of time, thereby improving the cooling effect on the other storage container.

[0083] In some embodiments, refer to Figures 10 to 12 As shown, the first air duct 421 is provided with a first air outlet 4211 and a second air outlet 4212, and the second air duct 422 is also provided with a first air outlet 4211 and a second air outlet 4212. The first air outlet 4211 supplies air to the first storage container 200, and the second air outlet 4212 supplies air to the second storage container 300. There can be multiple first air outlets 4211, and multiple first air outlets 4211 are arranged at intervals along the front and rear direction of the refrigeration equipment 1000. There can also be multiple second air outlets 4212, and multiple second air outlets 4212 are arranged at intervals along the front and rear direction of the refrigeration equipment 1000. The second temperature sensor 111 is located between the first air duct 421 and the second air duct 422.

[0084] This embodiment can be understood as being in Figure 9 Based on the previous embodiment, improvements were made to the arrangement of the first air duct 421 and the second air duct 422, as well as the arrangement positions of the first air outlet 4211 and the second air outlet 4212, compared to... Figure 9In this embodiment, both the first air duct 421 and the second air duct 422 can supply air to the first storage container 200 and the second storage container 300, thereby increasing the air volume and improving the cooling effect. The first air outlet 4211 evenly covers the first storage container 200, resulting in a more uniform air supply and preventing localized overfreezing of the first storage container 200. The first air duct 421 can be understood as the main air path, and the second air duct 422 can be understood as the auxiliary air path.

[0085] Reference Figure 6 , Figure 8 and Figure 11 As shown, in some embodiments, a third temperature sensor 310 is provided at the bottom of the second storage container 300. The third temperature sensor 310 is used to detect the temperature at the bottom of the second storage container 300, thereby determining the temperature of the food inside the second storage container 300. The controller can control the opening or closing of the first damper 411 and the second damper 412 according to the temperature values ​​detected by the first temperature sensor 210 and the third temperature sensor 310, thereby automatically and adaptively adjusting the airflow of the first air duct 421 and the airflow of the second air duct 422 according to the freezing status or load of the food in the first storage container 200 and the second storage container 300.

[0086] Reference Figure 18 As shown, in some embodiments, a control method for a refrigeration device is also provided. The control method includes steps S600 and S700, as detailed below.

[0087] S600: Acquire a first signal and a third signal, control the first damper to open intermittently, and control the second damper to remain closed. The first signal is characterized by the first temperature sensor detecting a value that is continuously lower than or equal to a preset temperature value within a preset time period, and the third signal is characterized by the third temperature sensor detecting a value that is continuously lower than or equal to a preset temperature value within a preset time period.

[0088] In this step, when the controller receives the first signal and the third signal, it indicates that the cooling demand of the first storage container 200 and the second storage container 300 is weak. At this time, the first damper 411 is controlled to open intermittently. For example, the first damper 411 is continuously closed for a first time and then continuously opened for a second time. At the same time, the second damper 412 needs to be kept closed. Keeping the second damper 412 closed can reduce the air volume supplied by the air supply channel 420 to the cooling space 110. The intermittent opening of the first damper 411 can realize the intermittent air supply from the first air duct 421 to the first storage container 200 and the second storage container 300, thereby maintaining the temperature of the first storage container 200 and the second storage container 300.

[0089] S700: Acquire a second signal or a fourth signal, and control the first damper and the second damper to remain open. The second signal is characterized by the first temperature sensor detecting a value that is continuously greater than a preset temperature value within a preset time period, and the fourth signal is characterized by the third temperature sensor detecting a value that is continuously greater than a preset temperature value within a preset time period.

[0090] In this step, when the controller receives the second or fourth signal, it indicates that the first storage container 200 or the second storage container 300 has a strong cooling demand. In order to quickly reduce the temperature of the cooling space 110, the first air damper 411 and the second air damper 412 are kept open, so that the first air duct 421 and the second air duct 422 deliver air to the cooling space 110 at maximum capacity, thereby quickly reducing the temperature of the cooling space 110 and cooling and preserving the food in the first storage container 200 or the second storage container 300 at a lower temperature, resulting in a faster cooling rate.

[0091] Reference Figure 21 As shown, this embodiment also provides a control method for controlling... Figure 6 or Figure 8 The refrigeration equipment in the middle is 1000.

[0092] Initially, similar to Figure 19 The control process first determines whether the refrigeration damper 430 is closed, and waits for the refrigeration damper 430 to close before proceeding to the next step; then, the temperature of the variable temperature compartment is controlled according to the temperature value of the second temperature sensor 111. When the temperature value of the second temperature sensor 111 is higher than -1℃, the first damper 411 and the second damper 412 open simultaneously to increase the air supply. When the temperature value of the second temperature sensor 111 is lower than -3℃, the first damper 411 and the second damper 412 close simultaneously to reduce the air supply and control the temperature of the variable temperature compartment between -3℃ and -1℃. Initially, the food is cooled in a normal low temperature environment.

[0093] Then, it is determined whether condition S3 is met. Condition S3 is that the temperature value of the first temperature sensor 210 is higher than -0.5℃ for 0.5h to 1h and the temperature value of the third temperature sensor 310 is higher than -0.5℃ for 0.5h to 1h. If condition S3 is met, it means that both the first storage container 200 and the second storage container 300 have strong refrigeration requirements. At this time, the temperature of the variable temperature compartment can be controlled between -6℃ and -4℃ according to the temperature value of the second temperature sensor 111, so that the variable temperature compartment freezes the food at a lower ambient temperature, which can improve the refrigeration rate.

[0094] Specifically, when the temperature value of the second temperature sensor 111 is below -6℃, the first damper 411 and the second damper 412 are closed simultaneously to reduce the air supply. When the temperature value of the second temperature sensor 111 is above -4℃, the first damper 411 and the second damper 412 are opened simultaneously to increase the air supply. This controls the temperature of the variable temperature chamber. Then, it is determined whether condition S6 is met. Condition S6 is that the temperature value of the first temperature sensor 210 is below or equal to -0.5℃ for 0.5h to 1h and the temperature value of the third temperature sensor 310 is below or equal to -0.5℃ for 0.5h to 1h. If condition S6 is met, it is determined that the food has been frozen or the food load is small, and the control process returns to the beginning of the entire process. If condition S6 is not met, the control process returns to before the judgment condition S3, and then the judgment condition S3 is re-judged.

[0095] If condition S3 is not met, then proceed to determine if condition S4 is met. Condition S4 is that the temperature value of the first temperature sensor 210 is higher than -0.5℃ for 0.5h to 1h and the temperature value of the third temperature sensor 310 is lower than or equal to -0.5℃ for 0.5h to 1h. If condition S4 is met, it indicates that the first storage container 200 has a strong cooling demand, while the second storage container 300 has a weak cooling demand. At this time, based on the temperature value of the second temperature sensor 111, the temperature of the variable temperature compartment can be controlled between -6℃ and -4℃, allowing the variable temperature compartment to freeze the food at a lower ambient temperature, which can improve the cooling rate. This is different from the temperature control steps under condition S3. Specifically, the first damper 411 remains open, and the second damper 412 is opened for 5-10 minutes and then closed for 10-20 minutes, repeating this cycle. That is, the second damper 412 is opened intermittently, so that the temperature of the variable temperature chamber is maintained between -6℃ and -4℃. Since the cooling demand of the second storage container 300 is relatively weak, the second damper 412 is opened intermittently to maintain the temperature of the second storage container 300. After the temperature of the variable temperature chamber is maintained between -6℃ and -4℃, it is then determined whether condition S6 is met. If condition S6 is met, the control process returns to the beginning of the entire process. If condition S6 is not met, it returns to before the judgment of condition S3 and re-judges condition S3.

[0096] If condition S4 is not met, then it is determined whether condition S5 is met. Condition S5 is that the temperature value of the first temperature sensor 210 is lower than or equal to -0.5℃ for 0.5h to 1h and the temperature value of the third temperature sensor 310 is higher than -0.5℃ for 0.5h to 1h. If condition S5 is met, it indicates that the second storage container 300 has a strong cooling demand, while the first storage container 200 has a weak cooling demand. At this time, the temperature of the variable temperature compartment can be controlled between -6℃ and -4℃ based on the temperature value of the second temperature sensor 111. The variable temperature chamber freezes food at a lower ambient temperature, which can improve the cooling rate. Similar to the temperature control steps under condition S4, the second damper 412 is kept open, and the first damper 411 is opened for 5 to 10 minutes and closed for 10 to 20 minutes. This will not be elaborated here. After the temperature of the variable temperature chamber is controlled between -6℃ and -4℃, it is then judged whether condition S6 is met. If condition S6 is met, the control process returns to the beginning of the entire process. If condition S6 is not met, it returns to the judgment before condition S3 and re-judges condition S3.

[0097] In the control flow of this embodiment, conditions S3, S4, and S5 are judged sequentially. Since condition S3 indicates that both storage containers have a strong cooling demand, it has a higher priority. Therefore, condition S3 is judged first. When conditions S3, S4, and S5 are not met, it can be directly concluded that the food has been frozen or the food load is large. There is no need to proceed to the step of judging condition S6. This embodiment can save the time spent in the judgment process and improve the cooling response speed by optimizing the order of judging the above conditions.

[0098] when Figure 21 Control methods applied to control Figure 12 In the embodiment, conditions S4 and S5 respectively indicate that only the first storage container 200 has a cooling requirement and only the second storage container 300 has a cooling requirement. Since the cold air in the first air duct 421 and the second air duct 422 preferentially flows into the first storage container 200 through the first air outlet 4211, the cooling rate of the first storage container 200 is faster, and food can be preferentially put into the first storage container 200. The cooling requirement of the first storage container 200 has a higher priority than the cooling requirement of the second storage container 300. Therefore, condition S4 is placed before condition S5 for judgment.

[0099] In some embodiments, refer to Figures 13 to 15As shown, the first air duct 421 is provided with a first air outlet 4211 and a second air outlet 4212. The second temperature sensor 111 is located inside the first air duct 421. The first air outlet 4211 supplies air to the first storage container 200, and the second air outlet 4212 supplies air to the second storage container 300. An air guide channel 500 is formed between the first storage container 200 and the second storage container 300. The air guide channel 500 connects the second air outlet 4212 and the second storage container 300. The air guide channel 500 can guide the cold air flow from the second air outlet 4212 from top to bottom into the second storage container 300. The second air duct 422 includes a first branch 4221 and a second branch 4222. The cold air flow in the second air duct 422 is diverted to the first branch 4221 and the second branch 4222. The first branch 4221 is provided with a third air outlet 4223, which is located on the rear side of the first storage container 200 and supplies air to the first storage container 200. The second branch 4222 is provided with a fourth air outlet 4224, which is located on the rear side of the second storage container 300 and supplies air to the second storage container 300.

[0100] Figure 13 The embodiments can be understood as being in Figure 10 Based on the previous embodiment, the second air duct 422 is further provided with a first branch 4221 and a second branch 4222 that respectively supply air to the first storage container 200 and the second storage container 300. This can increase the air supply volume and improve the cooling effect. The first branch 4221 and the second branch 4222 supply air from the rear side of each storage container, and the second air outlet 4212 of the first air duct 421 supplies air from the front side of the second storage container 300, resulting in a more uniform cooling effect.

[0101] Specifically, the first storage container 200 is located above the second storage container 300. Therefore, the first branch 4221 is located above the second branch 4222. The main direction of the cold air flow in the second air duct 422 is from top to bottom. Therefore, the cold air flow in the second air duct 422 will preferentially enter the higher-positioned first branch 4221 and preferentially supply air to the first storage container 200, resulting in a better cooling effect on the first storage container 200. Foods with high freezing requirements can be preferentially placed in the first storage container 200.

[0102] Reference Figure 22 The diagram shows the control method provided in this embodiment. This control flow is mainly aimed at controlling... Figure 11 or Figure 14The refrigeration equipment 1000 is used in the refrigerator compartment. First, it checks whether the refrigeration damper 430 is closed to determine if the refrigerator compartment 120 requires cooling. When the refrigeration damper 430 is open, it indicates that the refrigerator compartment 120 is requesting cooling; when the refrigeration damper 430 is closed, it indicates that the refrigerator compartment 120 does not currently require cooling. The cooling process for the variable temperature compartment proceeds only after the refrigeration damper 430 closes. This can be understood as separating the cooling processes for the refrigerator compartment 120 and the variable temperature compartment to ensure sufficient airflow. Then, the first damper 411 is opened and the second damper 412 is closed. At this time, the second air duct 422 is closed, and air is supplied to the first storage container 200 and the second storage container 300 only through the first air outlet 4211 and the second air outlet 4212 of the first air duct 421, respectively. The temperature is controlled according to the temperature value of the second temperature sensor 111. When the temperature value of the second temperature sensor 111 is lower than -3℃, the first air damper 411 is closed to reduce the air supply. When the temperature value of the second temperature sensor 111 is higher than -1℃, the first air damper 411 is opened until the temperature of the variable temperature chamber is maintained at -3℃ to -1℃.

[0103] Then, it is determined whether the following conditions are met: the temperature value of the first temperature sensor 210 remains below or equal to -0.5℃ for 0.5h to 1h, and the temperature value of the third temperature sensor 310 remains below or equal to -0.5℃ for 0.5h to 1h. If these conditions are not met, it indicates that both the first storage container 200 and the second storage container 300 have strong cooling requirements. The first air damper 411 and the second air damper 412 can be opened to supply air to the first storage container 200 and the second storage container 300 at maximum capacity, which can quickly reduce the temperature of the variable temperature compartment. Temperature control is then performed based on the temperature value of the second temperature sensor 111. When the temperature value of the second temperature sensor 111 is below -6℃, the first... When damper 411 and damper 412 are closed, the air supply is reduced. When the temperature value of the second temperature sensor 111 is higher than -4℃, damper 411 and damper 412 are opened to increase the air supply, so that the temperature value of the second temperature sensor 111 is maintained between -6℃ and 4℃. The food in the first storage container 200 and the second storage container 300 is cooled at a lower temperature, which can quickly reduce the temperature of the food and improve the cooling efficiency. If the above conditions are met, it is determined that the food in the first storage container 200 and the second storage container 300 has been frozen or the food load is small and the cooling demand is weak. The control process returns to the temperature control step of -3℃ to -1℃ to avoid overfreezing of the food.

[0104] 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 130 is the refrigeration element in the first refrigeration system, providing cooling to the refrigerator compartment 120 and the variable temperature compartment via the first evaporator 130. The second refrigeration system includes a second evaporator, providing 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 130 is the refrigeration element in this system, providing cooling to the refrigerator compartment 120, the variable temperature compartment, and the freezer compartment via the first evaporator 130.
