Description

Technical Field

[0001] This invention relates to the field of household appliance technology, specifically to a frost-free refrigerator, a control method for the frost-free refrigerator, and a computer device. Background Technology

[0002] Currently, frost-free refrigerators are becoming increasingly popular. Generally, frost-free refrigerators use forced convection cooling, meaning that cold air from the freezer compartment is directly blown into the refrigerator or variable-temperature compartment. This results in rapid cooling of the refrigerator or variable-temperature compartment. However, due to the high convection speed, food stored in the refrigerator or variable-temperature compartment can easily dry out, causing a rapid decline in its freshness. Furthermore, because there is air circulation between the freezer and refrigerator / variable-temperature compartments, it can also lead to the problem of odor transfer.

[0003] With consumers placing increasing emphasis on food preservation, the problems of food drying out too quickly and odors mixing between compartments in frost-free refrigerators are issues that urgently need to be addressed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an air-cooled refrigerator, a control method for the air-cooled refrigerator, and a computer device.

[0024] Secondly, in one embodiment, the present invention provides a control method for a frost-free refrigerator, applied to the frost-free refrigerator in any of the above embodiments; the control method for the frost-free refrigerator includes:

[0025] Obtain the target temperature of the target chamber;

[0026] If the target temperature in the target chamber does not meet the target cooling requirements, turn on the refrigeration fan and blow the cold air in the refrigeration chamber into the target air cavity through the air outlet.

[0027] In one embodiment, the air-cooled refrigerator further includes an air cavity partition disposed in the target air cavity, the air cavity partition dividing the target air cavity into a communicating target air inlet cavity and a target air return cavity, the air outlet including a target air inlet communicating with the freezer compartment and the target air inlet cavity and a target air return outlet communicating with the freezer compartment and the target air return cavity, and a first target air damper disposed at the connection between the target air inlet cavity and the target air inlet cavity; if the target temperature of the target compartment does not reach the target cooling requirement, the refrigeration fan is turned on, and the cold air in the freezer compartment is blown into the target air cavity through the air outlet by the refrigeration fan, including:

[0028] If the target temperature in the target chamber does not meet the target cooling requirements, the refrigeration fan and the first target damper are turned on. The refrigeration fan blows the cold air in the freezer chamber through the first target damper and the target air inlet into the target air inlet cavity, so that the cold air returns to the freezer chamber through the target air inlet cavity and the target return air cavity.

[0029] In one embodiment, the air-cooled refrigerator further includes a freezing evaporator disposed in the freezer compartment and a compressor connected to the freezing evaporator; the control method for the air-cooled refrigerator further includes:

The convection speed is slow, which prevents the food in the refrigerator compartment and / or variable temperature compartment from drying out quickly. It also solves the problem of "odor transfer" between the freezer compartment and the refrigerator compartment and / or variable temperature compartment, ultimately improving the preservation capacity of the refrigerator compartment and / or variable temperature compartment.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] In the description of this invention, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified. In this application, the term "exemplary" is used to mean "used as an example, illustration, or description." Any embodiment described as "exemplary" in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is provided to enable any person skilled in the art to make and use the invention. In the following description, details are set forth for illustrative purposes. It should be understood that those skilled in the art will recognize that the invention can be made without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid unnecessarily obscuring the description of the invention. Therefore, the invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0053] Firstly, such as Figure 1 As shown, in one embodiment, the present invention provides a frost-free refrigerator, comprising:

[0054] Freezer compartment and target compartment; the target compartment includes refrigerator compartment and / or variable temperature compartment;

[0055] It should be noted that, in order to make the description of the technical solution clearer, the following description will use a cold storage room as an example;

[0056] A refrigeration fan 7 is installed in the freezer compartment, and a target air cavity (including a refrigeration air cavity 1 installed in the refrigerator compartment) is installed in the target compartment.

[0057] Air vent 6 connects the freezer compartment and the refrigeration air chamber 1;

[0058] The refrigeration fan 7 is used to blow cold air from the freezer compartment into the refrigeration air chamber 1 through the air outlet 6 when refrigerating the refrigerator compartment;

[0059] Normally, the temperature of the freezer compartment is lower than that of the refrigerator compartment. Therefore, when the refrigerator compartment needs to be cooled, simply turn on the freezer fan 7. The freezer fan 7 blows the cold air from the freezer compartment into the refrigerator air chamber 1 through the air outlet 6, so that the refrigerator air chamber 1 is at a lower temperature, thereby exchanging heat with the food in the refrigerator compartment through natural convection, and completing the cooling of the food in the refrigerator compartment.

[0060] Among them, Figure 1As can be seen, the refrigeration air cavity 1 has only one opening and is connected to the air outlet 6. However, since the refrigeration fan 7 and the air outlet 6 are not completely fitted, it will not affect the cold air blown by the refrigeration fan 7 into the refrigeration air cavity 1 through the air outlet 6 and then back into the freezer compartment through the air outlet 6. Thus, it can also refresh the cold air in the refrigeration air cavity 1 to a certain extent, ensuring that the refrigeration air cavity 1 has a continuous and stable cooling capacity for the freezer compartment.

[0061] When the cold storage room is replaced by the variable temperature room, the specific structure and principle involved are the same as those of the cold storage room, and will not be repeated here. If the cold storage room and the variable temperature room exist at the same time, since the temperature requirements of the cold storage room and the variable temperature room are different, it is necessary to set up corresponding cold storage air cavity 1 and variable temperature air cavity in the cold storage room and the variable temperature room respectively. In this case, the cold storage air cavity 1 needs to pass through the variable temperature room.

[0062] By adding a corresponding refrigeration air cavity to the refrigerator compartment, the air circulation in the refrigeration air cavity is realized for cooling. Since the refrigeration air cavity is isolated from the refrigerator compartment, the convection mode in the refrigerator compartment is changed from strong convection to natural convection. The convection speed is slow, which avoids the food in the refrigerator compartment from drying out quickly. It also solves the problem of "odor crossing" between the freezer and refrigerator compartments, and ultimately improves the preservation ability of the refrigerator compartment.

[0063] like Figure 2 and Figure 3 As shown, in one embodiment, the above-mentioned air-cooled refrigerator further includes:

[0064] Air cavity partition 3 is installed in the refrigeration air cavity 1;

[0065] The air cavity partition 3 divides the target air cavity into a connected target air inlet cavity and a target air return cavity (specifically, the air cavity partition 3 divides the refrigerated air cavity 1 into a connected refrigerated air inlet cavity 11 and a refrigerated air return cavity 12).

[0066] The air vents include a target air inlet that connects the freezer compartment and the target air inlet cavity, and a target air return vent that connects the freezer compartment and the target air return cavity (specifically, the air vents include a refrigeration air inlet 61 that connects the freezer compartment and the refrigeration air inlet cavity 11, and a refrigeration air return vent 62 that connects the freezer compartment and the refrigeration air return cavity).

[0067] The refrigeration fan 7 is specifically used to blow cold air from the freezer compartment into the refrigeration air inlet 61 through the refrigeration air inlet 61, and the cold air returns to the freezer compartment through the refrigeration air inlet 11 and the refrigeration return airlet 12.

[0068] As mentioned in the above embodiments, since the refrigeration fan 7 and the air outlet 6 are not completely fitted, it does not affect the cold air blown by the refrigeration fan 7 into the refrigeration air cavity 1 through the air outlet 6 and then back into the freezer compartment through the air outlet 6. However, this method results in the temperature of the cold air blown into the refrigeration air cavity 1 not being equal to the temperature of the cold air in the freezer compartment (the refrigeration air cavity 1 contains two types of cold air: one is cold air that has completed heat exchange with the food in the refrigeration compartment, and the other is cold air that has just entered from the freezer compartment. The temperature of the first type of cold air is obviously lower than that of the second type of cold air, resulting in the temperature of the mixed cold air being higher than that of the pure second type of cold air), thereby reducing the refrigeration efficiency of the food in the refrigeration compartment, requiring more refrigeration time, and also increasing the power consumption of the refrigeration fan 7. Therefore, in view of this situation, this embodiment adds an air cavity partition 3 to the refrigeration air cavity 1, thereby... The refrigeration air chamber 1 is divided into a connected refrigeration air inlet chamber 11 and a refrigeration air return chamber 12. The refrigeration air inlet chamber 11 is close to the food in the refrigeration compartment. The position of the refrigeration fan 7 corresponds to the refrigeration air inlet 61, and the refrigeration air inlet 61 is only connected to the refrigeration air inlet chamber 11. Therefore, the cold air blown by the refrigeration fan 7 into the refrigeration compartment will only enter the refrigeration air inlet chamber 11 through the refrigeration air inlet 61. After the cold air in the refrigeration air inlet chamber 11 exchanges heat with the food in the refrigeration compartment, it directly enters the refrigeration air return chamber 12 connected to the refrigeration air inlet chamber 11, and then returns to the freezer compartment from the refrigeration air return port 62 connected to the refrigeration air return chamber 12, completing the one-way circulation of cold air. Compared with the method in the previous embodiment, it can ensure that the temperature of the cold air used for heat exchange is the same as the temperature of the cold air in the freezer compartment, thereby improving the refrigeration efficiency of the refrigeration compartment and reducing the power consumption of the refrigeration fan 7.

[0069] like Figure 2 and Figure 3 As shown, in one embodiment, the above-mentioned air-cooled refrigerator further includes:

[0070] A first target air damper (including a first refrigerated air damper 4 located at the connection between the target air inlet cavity and the target air inlet) is provided at the connection between the refrigerated air inlet cavity 11 and the refrigerated air inlet 61.

[0071] The first refrigeration air door 4 is used to open the refrigeration air inlet 11 and the refrigeration air inlet 61 or to block the refrigeration air inlet 11 and the refrigeration air inlet 61.

[0072] While the refrigeration of the refrigerator compartment is achieved through active air supply from the refrigeration fan 7, this active air supply only improves efficiency and achieves refrigeration in a short time. Conversely, if the refrigeration time requirement is not considered, the refrigeration fan 7 can be left running, allowing the cold air in the freezer compartment to flow naturally into the refrigeration air chamber 1. This analysis shows that if the freezer compartment and the refrigeration air chamber 1 remain continuously connected, the refrigerator compartment will still refrigerate even without the refrigeration fan 7, leading to an increased degree of refrigeration and potential damage to the food inside. Therefore, to address this issue, this embodiment adds a first refrigeration air damper 4 at the connection between the refrigeration air inlet chamber 11 and the refrigeration air inlet 61. This controls the first refrigeration air damper 4 to open only when the refrigerator compartment is being refrigerated, thereby preventing an increase in the degree of refrigeration in the refrigerator compartment.

[0073] In the scenario where air dampers are set, in the above embodiment, for the case where there are both a refrigerator compartment and a variable temperature compartment, only one air cavity can be set. This air cavity is distributed in both the refrigerator compartment and the variable temperature compartment. In order to achieve differentiated cooling between the refrigerator compartment and the variable temperature compartment, it is only necessary to set corresponding air dampers in the refrigerator compartment and the variable temperature compartment respectively, thereby saving the hardware cost of the air cavity.

[0074] In addition, the freezer compartment is also equipped with a freezer evaporator 8, a freezer air inlet 9, and a freezer air return vent 10. When the freezer compartment needs to be cooled, the freezer fan 7 and the compressor connected to the freezer evaporator 8 need to be started. Under the operation of the compressor, the temperature of the freezer evaporator 8 is very low, thereby reducing the temperature of the surrounding air. The freezer fan 7 blows the air cooled by the freezer evaporator 8 through the freezer air inlet 9 to various areas of the freezer compartment, thereby exchanging heat with the food in the freezer compartment and completing the cooling of the food in the freezer compartment.

[0075] As can be seen from the refrigeration processes of the refrigerator and freezer compartments, the refrigeration of the refrigerator compartment does not directly rely on the compressor and the evaporator 8. It only requires the refrigeration fan 7 to blow the cold air from the freezer compartment into the refrigerator air chamber 1. It should be noted that since the refrigeration of the refrigerator compartment requires heat exchange with the cold air in the freezer compartment, the temperature of the freezer compartment will rise as the temperature of the refrigerator compartment decreases. If this process causes the temperature of the freezer compartment to rise to a level that does not meet the refrigeration requirements of the freezer compartment, the compressor will be activated and the evaporator 8 will be used. That is, the refrigeration of the refrigerator compartment and the refrigeration of the freezer compartment are independent of each other, but can be carried out simultaneously.

[0076] like Figure 2 and Figure 3 As shown, in one embodiment, the above-mentioned air-cooled refrigerator further includes:

[0077] A second target air damper (including a second refrigerated air damper 5 located at the connection between the target return air cavity and the target return air inlet) is provided at the connection between the refrigerated return air cavity 12 and the refrigerated return air inlet 62;

[0078] The second refrigeration air damper 5 is used to open the refrigeration return air chamber 12 and the refrigeration return air outlet 62 or to block the refrigeration return air chamber 12 and the refrigeration return air outlet 62.

[0079] The specific function and background of the second refrigerated air door 5 are basically the same as those of the first refrigerated air door 4 in the above embodiment. The difference is that the first refrigerated air door 4 is set on the air inlet side, and the continuous conduction on the air inlet side has the greatest impact. The second refrigerated air door 5 is set on the air return side, and the continuous conduction on the air return side has the second greatest impact.

[0080] like Figure 2 As shown, in one embodiment, the above-mentioned air-cooled refrigerator further includes:

[0081] The target evaporator plate (including the refrigeration evaporator plate 2 installed on the refrigeration air cavity 1) is installed on the target air cavity;

[0082] The refrigeration evaporator plate 2 is used to promote heat exchange between the air in the refrigeration compartment and the refrigeration air cavity 1;

[0083] Among them, the refrigerated evaporator plate 2 is a metal plate, thereby improving the heat exchange capacity; specifically, the refrigerated evaporator plate 2 can be an aluminum plate, etc.

[0084] The refrigerated evaporator plate 2 includes a first side and a second side. The first side of the refrigerated evaporator plate 2 is close to the food in the refrigerated compartment, and the second side of the refrigerated evaporator plate 2 is close to the refrigerated air cavity 1. More specifically, the second side of the refrigerated evaporator plate 2 can be attached to the outer surface of the refrigerated air cavity 1 near the food in the refrigerated compartment, or the second side of the refrigerated evaporator plate 2 can be embedded into the interior of the refrigerated air cavity 1, so that the second side of the refrigerated evaporator plate 2 can directly contact the cold air in the refrigerated air cavity 1, thereby further improving the heat exchange capacity.

[0085] The control method for the air-cooled refrigerator in this embodiment of the invention is applied to the control device of the air-cooled refrigerator, which is set in a computer device; the computer device can be a terminal, such as a mobile phone or a tablet computer, or it can be a server or a service cluster composed of multiple servers.

[0086] like Figure 4 As shown, Figure 4This is a schematic diagram of an application scenario of the control method for an air-cooled refrigerator in an embodiment of the present invention. The application scenario of the control method for an air-cooled refrigerator in an embodiment of the present invention includes a computer device 100 (the computer device 100 integrates a control device for an air-cooled refrigerator), and a computer-readable storage medium corresponding to the control method for an air-cooled refrigerator is run in the computer device 100 to execute the steps of the control method for an air-cooled refrigerator.

[0087] Understandable Figure 4 The computer equipment in the application scenario of the control method for the air-cooled refrigerator shown, or the devices contained in the computer equipment, do not constitute a limitation on the embodiments of the present invention. That is, the number or type of equipment in the application scenario of the control method for the air-cooled refrigerator, or the number or type of devices contained in each equipment, do not affect the overall implementation of the technical solution in the embodiments of the present invention, and can all be considered as equivalent substitutions or derivatives of the technical solutions claimed in the embodiments of the present invention.

[0088] In this embodiment of the invention, the computer device 100 can be an independent device, or a network of devices or a cluster of devices. For example, the computer device 100 described in this embodiment of the invention includes, but is not limited to, a computer, a network host, a single network device, a set of multiple network devices, or a cloud device composed of multiple devices. The cloud device consists of a large number of computers or network devices based on cloud computing.

[0089] Those skilled in the art will understand that Figure 4 The application scenarios shown are merely one example corresponding to the technical solution of this invention and do not constitute a limitation on the application scenarios of the technical solution of this invention. Other application scenarios may include more than one example. Figure 4 The more or fewer computer devices shown, or the network connections of the computer devices, for example Figure 4 Only one computer device is shown in the diagram. It is understood that the scenario of the control method for the air-cooled refrigerator may also include one or more other computer devices, which are not specifically limited here. The computer device 100 may also include a memory for storing information related to the control method for the air-cooled refrigerator.

[0090] Furthermore, in the application scenario of the air-cooled refrigerator control method in this embodiment of the invention, the computer device 100 may be equipped with a display device, or the computer device 100 may not have a display device but may be communicatively connected to an external display device 200. The display device 200 is used to output the results of the execution of the air-cooled refrigerator control method in the computer device. The computer device 100 may access a background database 300 (the background database 300 may be the local storage of the computer device 100, or it may be located in the cloud), and the background database 300 stores information related to the air-cooled refrigerator control method.

[0091] It should be noted that, Figure 4 The application scenario of the control method for the air-cooled refrigerator shown is merely an example. The application scenario of the control method for the air-cooled refrigerator described in this embodiment of the invention is intended to more clearly illustrate the technical solution of this embodiment of the invention and does not constitute a limitation on the technical solution provided in this embodiment of the invention.

[0092] Based on the application scenarios of the control method for air-cooled refrigerators described above, an embodiment of the control method for air-cooled refrigerators is proposed.

[0093] Secondly, such as Figure 5 As shown, in one embodiment, the present invention provides a control method for a frost-free refrigerator, applied to the frost-free refrigerator in any of the above embodiments; the control method for the frost-free refrigerator includes:

[0094] Obtain the target temperature of the target room (including the refrigeration temperature of the cold storage room);

[0095] If the refrigeration temperature of the refrigerator compartment does not meet the refrigeration requirements, turn on the refrigeration fan and blow the cold air in the freezer compartment through the air outlet into the target air cavity (including the refrigeration air cavity);

[0096] It should be noted that the execution subject of the control method of the air-cooled refrigerator in this embodiment is the processor of the air-cooled refrigerator, and the processor is electrically connected to each device or apparatus that needs to be controlled (such as the refrigeration fan in this embodiment).

[0097] The specific refrigeration process and principle of the refrigerator compartment involved in this embodiment can be referred to the air-cooled refrigerator in the above embodiment, and will not be repeated here.

[0098] By using the control method of the above-mentioned air-cooled refrigerator, a corresponding target air cavity is added to the refrigerator compartment and / or variable temperature compartment. The target air cavity is used to achieve air circulation and cooling. Since the target air cavity is isolated from the refrigerator compartment and / or variable temperature compartment, the convection mode in the refrigerator compartment and / or variable temperature compartment is changed from strong convection to natural convection. The convection speed is slow, which avoids the food in the refrigerator compartment and / or variable temperature compartment from drying out quickly. It also solves the problem of "odor crossing" between the freezer compartment and the refrigerator compartment and / or variable temperature compartment, and ultimately improves the preservation capacity of the refrigerator compartment and / or variable temperature compartment.

[0099] like Figure 2As shown, in one embodiment, the air-cooled refrigerator further includes an air cavity partition (including an air cavity partition in the refrigerator air cavity) disposed in the target air cavity. The air cavity partition divides the target air cavity into a connected target air inlet cavity and a target air return cavity (specifically, the air cavity partition divides the refrigerator air cavity into a connected refrigerator air inlet cavity and a refrigerator air return cavity). The air outlet includes a target air inlet connecting the freezer compartment and the target air inlet cavity, and a target air return outlet connecting the freezer compartment and the target air return cavity (specifically, the air outlet includes a refrigerator air inlet connecting the freezer compartment and the refrigerator air inlet cavity, and a refrigerator air return outlet connecting the freezer compartment and the refrigerator air return cavity). A first target air damper (including a first refrigerator air damper disposed at the connection between the refrigerator air inlet cavity and the refrigerator air inlet cavity, i.e.) is disposed at the connection between the target air inlet cavity and the target air inlet. Figure 5 (Refrigeration air damper in the refrigerator compartment); if the refrigeration temperature of the refrigerator compartment does not meet the refrigeration requirements, the refrigeration fan is turned on, and the cold air in the freezer compartment is blown into the refrigeration air cavity through the air vents by the refrigeration fan, including:

[0100] If the target temperature of the refrigerator compartment does not meet the refrigeration requirements, turn on the refrigeration fan and the refrigeration damper. The refrigeration fan will blow the cold air in the freezer compartment through the refrigeration damper and the refrigeration air inlet into the refrigeration air inlet cavity, so that the cold air can return to the freezer compartment through the refrigeration air inlet cavity and the refrigeration return air cavity.

[0101] In this embodiment, the specific structure and corresponding principle can be referred to the air-cooled refrigerator in the above embodiment, and will not be repeated here.

[0102] like Figure 5 As shown, in one embodiment, the air-cooled refrigerator further includes a freezing evaporator disposed in the freezer compartment and a compressor connected to the freezing evaporator; the control method for the air-cooled refrigerator further includes:

[0103] Obtain the freezing temperature of the freezer compartment;

[0104] If the freezing temperature of the freezer compartment does not meet the freezing requirements, turn on the compressor and the refrigeration fan;

[0105] The compressor outputs liquid refrigerant to the evaporator, so that the liquid refrigerant in the evaporator is vaporized into gaseous refrigerant to absorb heat and cool the cold air. The refrigeration fan also controls the refrigeration fan to blow the cooled air from the evaporator to various areas of the freezer compartment.

[0106] After turning on the compressor, if the freezing temperature of the freezer compartment reaches the freezing and refrigeration requirements, then turn off the compressor.

[0107] After turning on the refrigeration fan, if the target temperature of the target compartment reaches the target refrigeration requirement (including the refrigeration temperature of the refrigerator compartment reaching the refrigeration requirement) and the freezing temperature of the freezer compartment reaches the freezing refrigeration requirement, then the refrigeration fan is turned off.

[0108] like Figure 5 As shown, in one embodiment, the air-cooled refrigerator also includes a heating device (i.e., Figure 5 The control method for an air-cooled refrigerator also includes: heating wires, defrost temperature sensors, and target evaporators (including refrigeration evaporators on the refrigeration air chamber) mounted on the target air chamber;

[0109] After turning on the compressor, refrigeration fan, and refrigerator damper, turn off the compressor, refrigeration fan, and refrigerator damper according to the defrost signal, and turn on the heating wire;

[0110] The defrost signal is generated by the processor, for example, based on a timer. If defrosting is set to occur every eight hours, the processor will determine to generate a defrost signal when it detects that eight hours have passed since the last defrost. In other embodiments, the defrost signal can also be generated in other ways, such as directly based on user input instructions. That is, when the user needs to actively defrost, the user inputs the corresponding defrost instruction, and the corresponding defrost signal is generated based on the defrost instruction.

[0111] Obtain the temperature from the defrost temperature sensor;

[0112] If the temperature of the defrost temperature sensor reaches the defrost execution temperature, the refrigeration fan and the refrigerator air damper will be turned on so that the refrigeration fan blows the hot air heated by the heating wire through the refrigerator air damper into the refrigerator air inlet cavity.

[0113] Among them, the defrosting execution temperature refers to the temperature index that can produce a positive effect on defrosting. For example, in this embodiment, the defrosting execution temperature can be set to above 0 degrees Celsius.

[0114] After turning on the refrigeration fan and the refrigerator damper, if the defrost temperature sensor reaches the defrost exit temperature, then turn off the refrigeration fan and the refrigerator damper to complete the defrosting of the refrigerator evaporator plate.

[0115] The defrost exit temperature can be set based on empirical values. For example, if this defrost method is used, the temperature of the defrost temperature sensor when the refrigerated evaporator plate completes defrosting is statistically analyzed under a large number of samples. The defrost exit temperature can be slightly higher than the average or maximum value of the temperature obtained based on all samples.

[0116] Thirdly, such as Figure 6 As shown, in one embodiment, the present invention provides a control device for a frost-free refrigerator, applied to the frost-free refrigerator in any of the above embodiments; the control device for the frost-free refrigerator includes:

[0117] The refrigerator temperature acquisition module is used to acquire the refrigerator temperature of the refrigerator compartment.

[0118] The refrigeration fan control module is used to turn on the refrigeration fan if the refrigeration temperature of the refrigerator compartment does not meet the refrigeration requirements, and blow the cold air in the freezer compartment into the refrigeration air cavity through the air outlet.

[0119] By using the control device of the aforementioned air-cooled refrigerator, a corresponding refrigeration air cavity is added to the refrigerator compartment. The refrigeration air cavity is used to achieve air circulation and refrigeration. Since the refrigeration air cavity is isolated from the refrigerator compartment, the convection mode in the refrigerator compartment is changed from strong convection to natural convection. The convection speed is slow, which prevents the food in the refrigerator compartment from drying out quickly. It also solves the problem of "odor crossing" between the freezer and refrigerator compartments, and ultimately improves the freshness preservation capacity of the refrigerator compartment.

[0120] In one embodiment, the air-cooled refrigerator further includes an air cavity partition disposed in the refrigeration air cavity, the air cavity partition dividing the refrigeration air cavity into a connected refrigeration air inlet cavity and a refrigeration air return cavity, the air outlets including a refrigeration air inlet connecting the freezer compartment and the refrigeration air inlet cavity and a refrigeration air return cavity connecting the freezer compartment and the refrigeration air return cavity, and a refrigeration air damper disposed at the connection between the refrigeration air inlet cavity and the refrigeration air inlet cavity; the control device of the air-cooled refrigerator further includes:

[0122] In one embodiment, the air-cooled refrigerator further includes a freezing evaporator disposed in the freezer compartment and a compressor connected to the freezing evaporator; the control device of the air-cooled refrigerator further includes:

[0123] The freezing temperature acquisition module is used to acquire the freezing temperature of the freezer compartment;

[0124] The compressor control module is used to turn on the compressor if the freezing temperature of the freezer compartment does not meet the refrigeration requirements, and control the compressor to output liquid refrigerant to the freezer evaporator, so that the liquid refrigerant in the freezer evaporator is vaporized into gaseous refrigerant to absorb heat and cool the cold air. The freezer fan control module is also used to turn on the freezer fan if the freezing temperature of the freezer compartment does not meet the refrigeration requirements, so that the freezer fan blows the cooled air from the freezer evaporator to various areas of the freezer compartment.

[0125] The compressor control module is also used to shut down the compressor if the freezing temperature of the freezer compartment reaches the freezing and refrigeration requirements after the compressor is turned on.

[0126] The refrigeration fan control module is also used to shut down the refrigeration fan if the refrigeration temperature of the refrigerator compartment reaches the refrigeration cooling requirement and the freezing temperature of the freezer compartment reaches the freezing cooling requirement after the refrigeration fan is turned on.

[0127] In one embodiment, the air-cooled refrigerator further includes a heating wire, a defrost temperature sensor, and a refrigerator evaporator plate disposed on the refrigerator air cavity; the control device of the air-cooled refrigerator further includes:

[0128] The heating wire control module is used to turn on the heating device according to the defrost signal after the compressor, refrigeration fan, and refrigerator damper are turned on; the compressor control module is also used to turn off the compressor according to the defrost signal after the compressor, refrigeration fan, and refrigerator damper are turned on; the refrigeration fan control module is also used to turn off the refrigeration fan according to the defrost signal after the compressor, refrigeration fan, and refrigerator damper are turned on; the refrigerator damper control module is used to close the refrigerator damper according to the defrost signal after the compressor, refrigeration fan, and refrigerator damper are turned on.

[0129] The defrost temperature acquisition module is used to acquire the temperature from the defrost temperature sensor.

[0130] The refrigeration fan control module is also used to turn on the refrigeration fan if the temperature of the defrost temperature sensor reaches the defrost execution temperature; the refrigerator air damper control module is also used to open the refrigerator air damper if the temperature of the defrost temperature sensor reaches the defrost execution temperature, so that the refrigeration fan blows the hot air heated by the heating device through the refrigerator air damper to the refrigerator air inlet cavity.

[0131] The refrigeration fan control module is also used to shut down the refrigeration fan if the defrost temperature sensor reaches the defrost exit temperature after the refrigeration fan and the refrigerator damper are turned on; the refrigerator damper control module is also used to close the refrigerator damper if the defrost temperature sensor reaches the defrost exit temperature after the refrigeration fan and the refrigerator damper are turned on, so as to complete the defrosting of the refrigerator evaporator plate.

[0132] Fourthly, in one embodiment, the present invention provides a computer device, such as... Figure 7 As shown, it illustrates the structure of the computer device involved in this invention, specifically:

[0133] The computer device may include components such as a processor 401 with one or more processing cores, a memory 402 with one or more computer-readable storage media, a power supply 403, and an input unit 404. Those skilled in the art will understand that... Figure 7 The structure of the computer device shown does not constitute a limitation on the computer device and may include more or fewer components than shown, or combine certain components, or have different component arrangements. Wherein:

[0134] The processor 401 is the control center of the computer device. It connects various parts of the computer device via various interfaces and lines, and performs various functions and processes data by running or executing software programs and / or modules stored in the memory 402, and by calling data stored in the memory 402, thereby providing overall monitoring of the computer device. Optionally, the processor 401 may include one or more processing cores; preferably, the processor 401 may integrate an application processor and a modem processor, wherein the application processor mainly handles the operating system, user interface, and computer programs, and the modem processor mainly handles wireless communication. It is understood that the modem processor may not be integrated into the processor 401.

[0135] The memory 402 can be used to store software programs and modules. The processor 401 executes various functional applications and data processing by running the software programs and modules stored in the memory 402. The memory 402 may mainly include a program storage area and a data storage area. The program storage area may store the operating system, computer programs required for at least one function (such as sound playback function, image playback function, etc.), etc.; the data storage area may store data created according to the use of the server, etc. In addition, the memory 402 may include high-speed random access memory, and may also include non-volatile memory, such as at least one disk storage device, flash memory device, or other volatile solid-state storage device. Accordingly, the memory 402 may also include a memory controller to provide the processor 401 with access to the memory 402.

[0136] The computer device also includes a power supply 403 that supplies power to the various components. Preferably, the power supply 403 can be logically connected to the processor 401 through a power management system, thereby enabling functions such as charging, discharging, and power consumption management through the power management system. The power supply 403 may also include one or more DC or AC power supplies, recharging systems, power fault detection circuits, power converters or inverters, power status indicators, and other arbitrary components.

[0138] Although not shown, the computer device may also include a display unit, etc., which will not be described in detail here. Specifically, in this embodiment, the processor 401 in the computer device loads the executable files corresponding to the processes of one or more computer programs into the memory 402 according to the following instructions, and the processor 401 runs the computer programs stored in the memory 402 to perform the following steps:

[0139] Obtain the target temperature of the target chamber;

[0140] If the target temperature in the target chamber does not meet the target cooling requirements, turn on the refrigeration fan and blow the cold air in the refrigeration chamber into the target air cavity through the air outlet.

[0141] By using the aforementioned computer equipment, corresponding target air cavities are added to the refrigerator compartment and / or variable temperature compartment, thereby utilizing the target air cavities to achieve air circulation and refrigeration. Since the target air cavities are isolated from the refrigerator compartment and / or variable temperature compartment, the convection mode in the refrigerator compartment and / or variable temperature compartment is changed from strong convection to natural convection. The convection wind speed is slow, which avoids the food in the refrigerator compartment and / or variable temperature compartment from drying out quickly. It also solves the problem of "odor transfer" between the freezer compartment and the refrigerator compartment and / or variable temperature compartment, ultimately improving the preservation capacity of the refrigerator compartment and / or variable temperature compartment.

[0142] Those skilled in the art will understand that all or part of the steps in any of the methods in the above embodiments can be performed by a computer program or by a computer program controlling related hardware.

[0144] Obtain the target temperature of the target chamber;

[0145] If the target temperature in the target chamber does not meet the target cooling requirements, turn on the refrigeration fan and blow the cold air in the refrigeration chamber into the target air cavity through the air outlet.

[0146] By using the aforementioned storage medium, corresponding target air cavities are added to the refrigerator compartment and / or variable temperature compartment, thereby utilizing the target air cavities to achieve air circulation and refrigeration. Since the target air cavities are isolated from the refrigerator compartment and / or variable temperature compartment, the convection mode in the refrigerator compartment and / or variable temperature compartment is changed from strong convection to natural convection. The convection wind speed is slow, which avoids the food in the refrigerator compartment and / or variable temperature compartment from drying out quickly. It also solves the problem of "odor transfer" between the freezer compartment and the refrigerator compartment and / or variable temperature compartment, ultimately improving the preservation capacity of the refrigerator compartment and / or variable temperature compartment.
