[0001] The present application relates to the technical field of air-cooled refrigerators, for example, to a control method and device for an air-cooled refrigerator, and an air-cooled refrigerator. Background Art

[0002] At present, air-cooled refrigerators are widely used in daily life and supermarket sales because of their ability to refrigerate and preserve food and other items. At present, air-cooled refrigerators usually set air outlets and return air outlets inside the refrigeration room, and set an evaporator in the air duct connecting the air outlet and the return air outlet to exchange heat with the return air flow, so that the cold air flow after heat exchange is blown from the air outlet into the refrigeration room to refrigerate and preserve food. When the humidity in the refrigeration room is high, the humid air flows to the evaporator through the return air outlet, which can easily cause frost on the evaporator and reduce the overall energy efficiency level of the air-cooled refrigerator.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] While the waterproof and breathable membrane intercepts moisture in the air flowing through the return air duct, it will cause a sharp drop in the humidity in the cold storage room. Although it can reduce the risk of frost on the evaporator, it will affect the preservation effect in the cold storage room and reduce the user experience.

[0038] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings.

[0042] In the embodiments of the present disclosure, smart home appliances refer to home appliances that are formed by introducing microprocessors, sensor technology, and network communication technology into home appliances. They have the characteristics of intelligent control, intelligent perception, and intelligent application. The operation process of smart home appliances often relies on the application and processing of modern technologies such as the Internet of Things, the Internet, and electronic chips. For example, smart home appliances can be connected to electronic devices to enable users to remotely control and manage the smart home appliances.

[0043] In the disclosed embodiments, the terminal device refers to an electronic device with a wireless connection function. The terminal device can communicate with the above-mentioned smart home appliances by connecting to the Internet, or can communicate with the above-mentioned smart home appliances directly through Bluetooth, WiFi, etc. In some embodiments, the terminal device is, for example, a mobile device, a computer, or a vehicle-mounted device built into a hover car, or any combination thereof. Mobile devices may include, for example, mobile phones, smart home devices, wearable devices, smart mobile devices, virtual reality devices, etc., or any combination thereof, wherein wearable devices include, for example: smart watches, smart bracelets, pedometers, etc.

[0044] Combination Figure 1-Figure 3As shown, in some embodiments, the air-cooled refrigerator includes: a refrigerating compartment 310, a return air vent 320 is arranged on the side wall of the refrigerating compartment 310, a waterproof and breathable module 330 is arranged at the return air vent 320, and the waterproof and breathable module 330 is movably arranged at the return air vent 320, and can partially or completely block the return air vent 320. In this way, the refrigerating compartment 310 is used to place food for refrigeration and preservation. By arranging a movable waterproof and breathable module 330 at the return air vent 320 in the refrigerating compartment 310, the return air vent 320 can be partially or completely blocked, and the area of ​​the return air vent 320 blocked by the waterproof and breathable module 330 can intercept moisture in the return air flow. In the case where the ambient humidity inside the refrigerating compartment 310 is relatively high, the return air vent 320 is partially or completely blocked by driving the waterproof and breathable membrane to move, intercepting moisture in the return air flow flowing through the return air vent 320, and reducing the risk of frost on the evaporator 350.

[0045] Optionally, the air-cooled refrigerator further includes: a housing 300. The refrigerating chamber 310 is defined by the housing 300, and a heat exchange channel 340 is further defined inside the housing 300. The air outlet of the refrigerating chamber 310 is connected to one end of the heat exchange channel 340, and the return air outlet 320 is connected to the other end of the heat exchange channel 340. The evaporator 350 is disposed in the heat exchange channel 340. In this way, the airflow in the refrigerating chamber 310 flows into the heat exchange channel 340 through the return air outlet 320 to exchange heat with the evaporator 350, and the airflow after heat exchange is blown out from the air outlet, thereby maintaining a refrigerated and fresh-keeping environment in the refrigerating chamber 310.

[0046] Optionally, the return air outlet 320 is a rectangular opening, and guide rails 321 are provided at the opposite edges of the return air outlet 320. The waterproof and breathable module 330 is movably clamped between the two guide rails 321. A driving motor 360 is provided on one side of the guide rail 321. The output end of the driving motor 360 is engaged with the side of the waterproof and breathable module 330 to drive the waterproof and breathable module 330 to move along the guide rail 321. In this way, the movement of the waterproof and breathable module 330 is guided by the guide rail 321, so that the waterproof and breathable module 330 can accurately block part or all of the area of ​​the return air outlet 320, and the waterproof and breathable module 330 is driven to move by the driving motor 360, thereby improving the activity adjustment efficiency of the waterproof and breathable module 330.

[0047] Optionally, the waterproof breathable module 330 includes: a mounting frame and a waterproof breathable membrane. The shape of the mounting frame is adapted to the shape of the return air outlet 320, the waterproof breathable membrane is arranged on the inner side of the mounting frame, the two opposite sides of the mounting frame are respectively clamped in the corresponding guide rails 321, and a rack is arranged on the side of the mounting frame located in the guide rail 321 on the side where the drive motor 360 is located, and the rack is meshed with the output end of the drive motor 360. In this way, the waterproof breathable membrane is supported by the mounting frame, and the waterproof breathable membrane is used to intercept moisture in the return air flow.

[0048] Optionally, a water receiving pan 370 is provided below the waterproof and breathable module 330 to receive the water intercepted by the waterproof and breathable module 330. The lower end of the water receiving pan 370 is connected to a drain pipe 371, and the water outlet of the drain pipe 371 is located above the condenser 390 of the air-cooled refrigerator. In this way, the water intercepted by the waterproof and breathable module 330 can be received by the water receiving pan 370, and the water received by the water receiving pan 370 can be discharged to the condenser 390 through the drain pipe 371 to assist in cooling, or to clean and remove dust from the condenser 390.

[0049] Optionally, a water pump 372 is connected to the drain pipe 371. In this way, the water pump 372 provides drainage pressure to extract water in the water receiving pan 370 and discharge it to the condenser 390.

[0050] Optionally, the air-cooled refrigerator further includes: an atomizer 380. The atomizer 380 is disposed at the air outlet of the refrigerating compartment 310, and the water inlet of the atomizer 380 is connected to the water receiving tray 370 through a water supply pipe. In this way, when the food in the refrigerating compartment 310 needs to be stored in an environment with a certain humidity, the water collected in the water receiving tray 370 can be extracted by the atomizer 380 for atomization, and then the atomized water vapor is carried by the outlet air flow and diffused into the refrigerating compartment 310. At this time, the water in the return air flow can be intercepted by the waterproof and breathable module 330 to reduce the risk of frosting of the evaporator 350, and the humidity level in the refrigerating compartment 310 can be guaranteed to ensure the preservation effect of the food.

[0051] Combination Figure 4 As shown, in one embodiment, a control method for an air-cooled refrigerator includes:

[0052] S01, the processor obtains the ambient humidity in the cold storage room;

[0053] S02, the processor determines the target activity position of the waterproof and breathable module according to the humidity range of the ambient humidity of the refrigerated compartment;

[0054] S03, the processor controls the waterproof and breathable module to move to the target active position to adjust the area of ​​the return air outlet water permeable region.

[0055] By adopting the control method for air-cooled refrigerators provided by the embodiment of the present disclosure, by setting an active waterproof and breathable module at the return air outlet in the refrigerator room, the return air outlet can be partially or completely blocked, and the area of ​​the return air outlet blocked by the waterproof and breathable module can intercept the moisture in the return air flow, and the area not blocked by the waterproof and breathable module can allow the moisture in the return air flow to pass normally, which is regarded as a permeable area. The target active position of the waterproof and breathable module is controlled according to the humidity level in the refrigerator room, so that the permeable area of ​​the return air outlet matches the current humidity level in the refrigerator room, which can not only intercept the moisture in the return air flow appropriately, but also avoid a sharp drop in the humidity level in the refrigerator room, thereby reducing the risk of frost on the evaporator while ensuring the preservation effect of the food in the refrigerator room.

[0056] It can be understood that the ambient humidity of the refrigerated compartment obtained by the processor is relative humidity.

[0057] Optionally, the processor obtains the ambient humidity in the cold storage room, including: the processor obtains the ambient humidity sent by a humidity sensor arranged inside the condensing room. In this way, a humidity sensor is arranged inside the cold storage room to detect the ambient humidity in the cold storage room, and the processor obtains the ambient humidity sent by the humidity sensor, which simplifies the process of obtaining the ambient humidity and improves the accuracy of obtaining.

[0058] Optionally, a plurality of humidity sensors are arranged inside the cold storage compartment, and the plurality of humidity sensors are evenly distributed on the inner wall of the cold storage compartment. The processor obtains the ambient humidity sent by the humidity sensors arranged inside the condensing compartment, including: the processor obtains a plurality of ambient humidity values ​​sent by the plurality of humidity sensors, and determines the average value of the plurality of ambient humidity values ​​as the ambient humidity of the cold storage compartment. In this way, the processor can further improve the accuracy of the obtained ambient humidity by obtaining a plurality of ambient humidity values ​​sent by humidity sensors arranged at a plurality of positions inside the cold storage compartment, and determining the average value as the current ambient humidity of the cold storage compartment, so that the obtained ambient humidity can better reflect the current humidity condition of the cold storage compartment, and more accurately control the position of the waterproof and breathable module.

[0059] Optionally, the processor determines the target active position of the waterproof and breathable module according to the humidity interval of the ambient humidity of the cold storage compartment, including: the processor determines the target active position of the waterproof and breathable module to be the first position when the ambient humidity of the cold storage compartment is in the first humidity interval; the processor determines the target active position of the waterproof and breathable module to be the second position when the ambient humidity of the cold storage compartment is in the second humidity interval; wherein the maximum value in the first humidity interval is less than the minimum value in the second humidity interval, and the area of ​​the water permeable area of ​​the return air outlet when the waterproof and breathable module is in the first position is greater than the area of ​​the water permeable area of ​​the return air outlet when the waterproof and breathable module is in the second position. In this way, when the ambient humidity of the cold storage compartment is in the relatively low first humidity interval, the moisture content of the return air flow is relatively low at this time, and the risk of frosting of the evaporator is relatively low. Therefore, the processor controls the waterproof and breathable module to move to the first position, at which time the area of ​​the water permeable area of ​​the return air outlet is relatively large, and the moisture in the return air flow can circulate through the return air outlet to maintain the humidity level inside the cold storage compartment. When the ambient humidity of the cold storage compartment is in the relatively high second humidity interval, the moisture content of the return air flow is relatively large at this time, and the risk of frosting of the evaporator is relatively high. Therefore, the processor controls the waterproof and breathable module to move to the second position. At this time, the area of ​​the water permeable region of the return air outlet is relatively small. The waterproof and breathable module is used to intercept most of the moisture in the return air flow to reduce the risk of frosting of the evaporator.

[0060] Exemplarily, the first humidity interval is greater than 30% and less than or equal to 50%; the second humidity interval is greater than 50% and less than or equal to 75%; when the waterproof and breathable module moves to the first position, one quarter of the return air outlet is blocked; when the waterproof and breathable module moves to the second position, three quarters of the return air outlet is blocked.

[0061] Optionally, the processor determines the target active position of the waterproof and breathable module according to the humidity interval of the ambient humidity of the refrigerated compartment, and further includes: when the ambient humidity of the refrigerated compartment is in the third humidity interval, the processor determines the target active position of the waterproof and breathable module to be the third position; when the ambient humidity of the refrigerated compartment is in the fourth humidity interval, the processor determines the target active position of the waterproof and breathable module to be the fourth position; wherein the maximum value in the third humidity interval is less than the minimum value in the first humidity interval, and the minimum value in the fourth humidity interval is greater than the maximum value in the second humidity interval; when the waterproof and breathable module is in the third position, the area of ​​the water permeable area of ​​the return air outlet is greater than the area of ​​the water permeable area of ​​the return air outlet when the waterproof and breathable module is in the first position; when the waterproof and breathable module is in the fourth position, the area of ​​the water permeable area of ​​the return air outlet is less than the area of ​​the water permeable area of ​​the return air outlet when the waterproof and breathable module is in the second position. In this way, when the ambient humidity inside the refrigerated compartment is in the relatively lower third humidity interval, the risk of frosting of the evaporator is further reduced, so the waterproof and breathable module is controlled to move to the third position to further increase the area of ​​the water permeable area of ​​the return air outlet. When the ambient grayscale inside the cold storage room is in the relatively higher fourth humidity range, the risk of frosting on the evaporator is further increased. Therefore, the waterproof and breathable module is controlled to move to the fourth position to further reduce the area of ​​the water permeable region of the return air outlet and further intercept the moisture in the return air flow.

[0062] Exemplarily, the third humidity interval is an interval less than or equal to 30%, and the fourth humidity interval is an interval greater than 75% and less than or equal to 100%. When the waterproof and breathable module moves to the third position, the return air outlet is in a fully open state; when the waterproof and breathable module moves to the fourth position, the entire area of ​​the return air outlet is blocked.

[0063] It can be understood that different humidity intervals correspond to different target activity positions of the waterproof and breathable module, and the binding relationship between the humidity interval and the target activity position is pre-stored in the database of the processor. When the processor determines the humidity interval in which the current ambient humidity of the refrigerated compartment is located, the target activity position of the waterproof and breathable module can be determined based on the corresponding relationship. There can also be a variety of corresponding relationships between the humidity interval and the target activity position, which will not be elaborated here.

[0064] Optionally, the processor controls the waterproof breathable module to move to the target active position, including: the processor controls the drive motor to drive the waterproof breathable module to move to the target active position. In this way, since the waterproof breathable module is driven by the drive motor, the processor controls the waterproof breathable module to move to the target active position, that is, controls the drive motor to drive the waterproof breathable module to move to the target active position.

[0065] Exemplarily, different target active positions of the waterproof and breathable module correspond to different driving strokes of the driving motor. The processor determines the corresponding driving stroke according to the determined target active position, and then controls the driving motor to run the determined driving stroke to drive the waterproof and breathable module to the target active position.

[0066] Combination Figure 5 As shown, in another embodiment, a control method for an air-cooled refrigerator includes:

[0067] S01, the processor obtains the ambient humidity in the cold storage room;

[0068] S02, the processor determines a target activity position of the waterproof and breathable module according to the humidity range of the ambient humidity of the refrigerated compartment;

[0069] S03, the processor controls the waterproof and breathable module to move to the target active position to adjust the area of ​​the return air outlet water permeable area;

[0070] S04, the processor obtains the type of food stored in the cold storage room;

[0071] S05, the processor determines the ambient humidity in the cold storage room suitable for storage according to the type of food;

[0072] S06: The processor further controls the area of ​​the water permeable region of the return air outlet according to the ambient humidity suitable for storage in the cold storage room.

[0073] With the control method for an air-cooled refrigerator provided by the embodiment of the present disclosure, after the processor adjusts the area of ​​the water permeable area of ​​the return air outlet according to the ambient humidity of the refrigerated compartment, it is necessary to take into account the storage and preservation effect of the food in the refrigerated compartment. Since different food ingredients have different suitable storage humidity environments, the processor obtains the type of food in the refrigerated compartment, determines the suitable storage ambient humidity according to the type of food ingredient, and then further controls the area of ​​the water permeable area of ​​the return air outlet, thereby reducing the risk of frost on the evaporator while taking into account the storage and preservation effect of the food ingredients in the refrigerated compartment.

[0074] Optionally, the processor further controls the area of ​​the water permeable region of the return air outlet according to the ambient humidity suitable for storage in the cold storage room, including: when the ambient humidity suitable for storage in the cold storage room is greater than the current ambient humidity in the cold storage room, the processor controls the area of ​​the water permeable region of the return air outlet to increase or remain unchanged; when the ambient humidity suitable for storage in the cold storage room is less than or equal to the current ambient humidity in the cold storage room, the processor controls the area of ​​the water permeable region of the return air outlet to decrease. In this way, when the ambient humidity suitable for storage in the cold storage room is greater than the current ambient humidity, in order to avoid further reduction of the current ambient humidity, the processor controls the area of ​​the water permeable region of the return air outlet to increase or remain unchanged. When the ambient humidity suitable for storage in the cold storage room is less than or equal to the current ambient humidity, in order to further reduce the ambient humidity in the cold storage room and make it closer to the ambient humidity suitable for storage, the processor controls the area of ​​the water permeable region of the return air outlet to decrease.

[0075] Taking the waterproof and breathable module as an example, when the waterproof and breathable module moves upward, the area blocked by the return air outlet gradually increases, and when the waterproof and breathable module moves downward, the area blocked by the return air outlet gradually decreases. The processor controls the increase of the area of ​​the water-permeable area of ​​the return air outlet, including: the processor controls the drive motor to drive the waterproof and breathable module to move downward, so that the area of ​​the water-permeable area of ​​the return air outlet increases. The processor controls the decrease of the area of ​​the water-permeable area of ​​the return air outlet, including: the processor controls the drive motor to drive the waterproof and breathable module to move upward, so that the area of ​​the water-permeable area of ​​the return air outlet decreases.

[0076] Optionally, the processor controls the driving motor to drive the waterproof breathable module to move downward, including: the processor determines the target moving distance of the waterproof breathable module according to the humidity difference between the ambient humidity suitable for storage in the refrigerated compartment and the current ambient humidity; the processor controls the driving motor to drive the waterproof breathable module to move downward by the target moving distance. In this way, the adjustment distance of the waterproof breathable module is associated with the humidity difference, and the area of ​​the water permeable area of ​​the return air outlet is adjusted more accurately, so that the ambient humidity in the refrigerated compartment is closer to the ambient humidity suitable for storage.

[0077] Optionally, the processor controls the drive motor to drive the waterproof and breathable module to move upward, including: the processor determines a target moving distance of the waterproof and breathable module based on a humidity difference between a current ambient humidity of the refrigerated compartment and an ambient humidity suitable for storage; the processor determines a target moving distance of the waterproof and breathable module based on the humidity difference; the processor controls the drive motor to drive the waterproof and breathable module to move upward a target moving distance.

[0078] Optionally, the processor determines the suitable storage environment humidity in the cold storage room according to the type of food, including: when there are multiple types of food stored in the cold storage room, the processor determines the suitable storage environment humidity for each food according to the type of food, and determines the average of multiple suitable storage environment humidity values ​​as the suitable storage environment humidity in the cold storage room. In this way, since multiple types of food may be stored in the cold storage room at the same time, in order to take into account the storage and preservation effects of multiple types of food, the processor determines the corresponding suitable storage environment humidity according to the type of each food, and then determines the average of multiple suitable storage environment humidity values ​​as the suitable storage environment humidity in the cold storage room.

[0079] Exemplarily, different types of ingredients have different suitable storage humidity. For example, the suitable storage humidity for meat ingredients is 45%, the suitable storage humidity for vegetable ingredients is 60%, and the suitable storage humidity for pastry ingredients is 30%. When the types of ingredients stored in the cold storage room are "meat", "vegetables" and "pastry", the processor obtains suitable storage humidity values ​​of 45%, 60% and 30% respectively, and then determines the average value of the three, 45%, as the suitable storage humidity in the cold storage room.

[0080] It is understandable that a camera can be installed in the cold storage room, and the processor uses the camera to obtain the type of stored food, which will not be elaborated here.

The processor obtains the coil temperature of the condenser of the air-cooled refrigerator, and uses the water intercepted by the waterproof and breathable module to spray and cool the condenser when the coil temperature is high, so as to make full use of the intercepted water.

[0088] Optionally, the processor controls the water intercepted by the waterproof and breathable module to be sprayed above the condenser, including: the processor controls a water pump connected to the drain pipe to start, and the water in the water receiving tray is pumped by the water pump to be sprayed above the condenser.

[0089] Optionally, a temperature sensor is provided at the coil of the condenser, and the processor obtains the coil temperature of the condenser of the air-cooled refrigerator, including: the processor obtains the coil temperature of the condenser sent by the temperature sensor.

[0090] It is understandable that the threshold value can be set at the factory according to the type of the air-cooled refrigerator, which will not be elaborated here.

[0091] Combination Figure 7 As shown, in another embodiment, a control method for an air-cooled refrigerator includes:

[0092] S01, the processor obtains the ambient humidity in the cold storage room;

[0093] S02, the processor determines a target activity position of the waterproof and breathable module according to the humidity range of the ambient humidity of the refrigerated compartment;

[0097] By adopting the control method for an air-cooled refrigerator provided by the embodiment of the present disclosure, the waterproof and breathable module can intercept moisture in the return airflow, and the intercepted moisture can flow into the water receiving tray for storage.

[0099] It will be appreciated that the set zone value may be factory set according to the type of condenser.

[0100] Combination Figure 8 As shown, in another embodiment, a control method for an air-cooled refrigerator includes:

[0101] S01, the processor obtains the ambient humidity in the cold storage room;

[0102] S02, the processor determines the target activity position of the waterproof and breathable module according to the humidity range of the ambient humidity of the refrigerated compartment;

[0103] S03, the processor controls the waterproof and breathable module to move to the target active position to adjust the area of ​​the return air outlet water permeable area;

[0104] S04, the processor obtains the type of food stored in the cold storage room;

[0105] S05, the processor determines the ambient humidity in the cold storage room suitable for storage according to the type of food;

[0106] S11, the processor controls the opening and closing of the atomizer according to the ambient humidity suitable for storage in the cold storage room and the current ambient humidity.

[0107] By adopting the control method for an air-cooled refrigerator provided by the embodiment of the present disclosure, the processor controls the opening and closing of the atomizer according to the relationship between the ambient humidity suitable for storing food and the current ambient humidity, and no longer further controls the active position of the waterproof and breathable module. The intervention of the atomizer makes the ambient humidity in the cold storage room close to the ambient humidity suitable for storage, and at the same time the risk of frosting of the evaporator is further reduced.

[0108] Optionally, the processor controls the opening and closing of the atomizer according to the size of the ambient humidity suitable for storage in the cold storage room and the current ambient humidity, including: when the ambient humidity suitable for storage in the cold storage room is greater than the current ambient humidity, the processor controls the atomizer to open and extracts water from the water receiving tray for atomization. In this way, when the ambient humidity suitable for storage in the cold storage room is greater than the current ambient humidity, the current ambient humidity in the cold storage room is relatively low and not suitable for the storage and preservation of food. Therefore, the atomizer is controlled to open and the water in the water receiving tray is extracted for atomization. The atomized water vapor is carried by the outlet air flow to circulate in the cold storage room, thereby increasing the humidity level in the cold storage room. At the same time, as the ambient humidity in the cold storage room increases, the area of ​​the water permeable area of ​​the return air outlet is further reduced, thereby further reducing the risk of frosting of the evaporator.
