Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to an air duct structure and a refrigerator using the same. Background Art

[0002] Currently, single-system refrigerators typically consist of a compressor, a freezing duct, a freezing fan, a refrigerator damper, and a refrigerator duct. When the freezer compartment needs to be cooled independently, the refrigerator damper is closed, the compressor begins cooling, and the cold air is transported through the freezing duct to the freezer compartment. The freezing fan then blows cold air into the freezer compartment, providing cooling for the freezer compartment. When the refrigerator compartment needs to be cooled, the refrigerator damper is opened, and the freezing fan blows air into the freezer compartment, while also transferring some of the cold air to the refrigerator duct. This cold air is then transported through the refrigerator duct to the refrigerator compartment, where it is then supplied to the refrigerator compartment.

[0003] Therefore, traditional single-system refrigerators cannot cool the refrigerator compartment independently. Cold air must be supplied to the refrigerator compartment through the freezer duct. This can easily lead to the freezer compartment temperature being too low while the refrigerator compartment has not yet reached the shutdown point, resulting in increased energy consumption and difficulty achieving the desired cooling effect. To achieve independent cooling of the refrigerator compartment, a dual-cooling system is usually used, with a separate compressor installed in the refrigerator compartment to cool the refrigerator compartment independently, significantly increasing the cost of the refrigerator.

[0060] See also Figure 1 The working principle of the air duct structure and the refrigerator using the same provided by the present invention is as follows:

[0061] When the refrigeration damper 5 is opened and the freezing damper 6 is closed, the movable fan 7 is driven by the driving device to move along the freezing air duct to the refrigeration air supply position opposite the refrigeration air inlet 211. At this time, the movable fan 7 is used to deliver cold air to the refrigerator chamber 2 alone, and the refrigerator is in the refrigerator chamber 2 alone cooling mode.

[0062] When the refrigeration damper 5 is closed and the freezing damper 6 is opened, the movable fan 7 is driven by the driving device to move along the freezing air duct to the freezing air supply position facing the freezing air inlet 311. At this time, the movable fan 7 is used to deliver cold air to the freezer chamber 3 alone, and the refrigerator is in the freezer chamber 3 alone cooling mode.

[0063] When both the refrigeration damper 5 and the freezing damper 6 are opened, the movable fan 7 is driven by the driving device to move along the freezing air duct to the intermediate air supply position between the refrigeration air inlet 211 and the freezing air inlet 311. At this time, the movable fan 7 is used to simultaneously deliver cold air to the refrigerator compartment 2 and the freezer compartment 3 respectively, and the refrigerator is in a simultaneous cooling mode for the refrigerator compartment 2 and the freezer compartment 3.

[0064] See also Figure 1 The air duct structure provided by the present invention and the corresponding control method of the refrigerator using the same are as follows:

[0065] First, set the various fixed positions of the active fan 7 along the cold air supply duct 4. For example, the above-mentioned refrigerated air supply position facing the refrigerated air inlet 211 is the upward operation point, the above-mentioned refrigerated air supply position facing the frozen air inlet 311 is the downward operation point, and the intermediate air supply position between the refrigerated air inlet 211 and the frozen air inlet 311 is the intermediate operation point. Based on the different operating positions of the active fan 7, the following three control methods can be provided:

[0066] Control method 1: When the temperature detection device of the refrigerator detects that the temperatures inside the refrigerating chamber 2 and the freezing chamber 3 have risen to the point where cooling is required, the linear drive mechanism of the drive device drives the movable fan 7 to move along the guide support structure 10 to the intermediate operating point, so that the movable fan 7 reaches the intermediate air supply position between the refrigerating air inlet 211 and the freezing air inlet 311, and the control device of the refrigerator controls the refrigerating air door 5 and the freezing air door 6 to remain open. The control device of the refrigerator starts timing and calculates the cooling rate of the refrigerating chamber 2 and the freezing chamber 3 within ten minutes. If the cooling rate of the refrigerating chamber 2 is measured to be approximately equal to the cooling rate of the freezing chamber 3, the position of the movable fan 7 remains unchanged at the intermediate air supply position.

[0067] If the cooling rate of the refrigerator compartment 2 is measured to be lower than the cooling rate of the freezer compartment 3, the control device controls the driving device to drive the movable fan 7 to move upward until it reaches or approaches the upward movement point, so that the movable fan 7 reaches or approaches the refrigerated air supply position directly opposite the refrigerated air inlet 211; if the cooling rate of the refrigerator compartment 2 is measured to be higher than the cooling rate of the freezer compartment 3, the control device controls the driving device to drive the movable fan 7 to move downward until it reaches or approaches the downward movement point, so that the movable fan 7 reaches or approaches the refrigerated air supply position directly opposite the refrigerated air inlet 311.

[0068] If it is measured that the temperature in the freezer compartment 3 reaches the set temperature first, the control device controls the driving device to drive the movable fan 7 to move upward until it reaches or approaches the upward movement point, so that the movable fan 7 reaches or approaches the refrigerated air supply position facing the refrigerated air inlet 211, and the control device of the refrigerator controls the freezing air door 6 to close. At this time, no cold air is supplied to the freezer compartment 3, and the refrigeration system of the refrigerator concentrates on supplying cold air to the refrigerating compartment 2 for cooling.

[0069] If it is measured that the temperature in the refrigerating chamber 2 reaches the set temperature first, the control device controls the driving device to drive the movable fan 7 to move downward until it reaches or approaches the downward movement point, so that the movable fan 7 reaches or approaches the refrigerated air supply position facing the refrigerated air inlet 311, and the control device of the refrigerator controls the refrigerating air door 5 to close. At this time, no cold air is supplied to the refrigerating chamber 2, and the refrigeration system of the refrigerator concentrates on supplying cold air to the freezer chamber 3 for cooling.

[0070] Control method two: When the temperature detection device of the refrigerator detects that the temperature inside the freezer compartment 3 reaches the refrigeration standard, and the temperature inside the refrigerator compartment 2 rises to the point where separate refrigeration is required, the control device controls the driving device to drive the movable fan 7 to move upward until it reaches or approaches the upward movement point, so that the movable fan 7 reaches or approaches the refrigerated air supply position facing the refrigerated air inlet 211, and the control device of the refrigerator controls the freezing damper 6 to close. At this time, no cold air is supplied to the freezer compartment 3, and the refrigeration system of the refrigerator concentrates on supplying cold air to the refrigerated compartment 2 for cooling.

[0071] Control method three: When the temperature detection device of the refrigerator detects that the temperature inside the refrigerating chamber 2 reaches the refrigeration standard, and the temperature inside the freezer chamber 3 rises to the point where separate refrigeration is required, the control device controls the driving device to drive the movable fan 7 to move downward until it reaches or approaches the downward movement point, so that the movable fan 7 reaches or approaches the refrigerated air supply position facing the refrigerated air inlet 311, and the control device of the refrigerator controls the refrigeration damper 5 to close. At this time, no cold air is supplied to the refrigerating chamber 2, and the refrigeration system of the refrigerator concentrates on supplying cold air to the freezer chamber 3 for cooling.

[0072] By utilizing the above-described air supply ducts and the structural layout and control logic of the refrigerator employing them, it is possible to achieve independent or simultaneous cooling of the refrigerator compartment 2 and the freezer compartment 3 at a low cost, without adding a refrigeration system or compressor 8, by modifying the air duct layout and adding software control logic to the existing refrigerator structure, thereby reducing operating energy consumption. Furthermore, this reduces odor transfer between the refrigerator compartment 2 and the freezer compartment 3, improving the user experience.

[0073] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the utility model.
