[0040] The switch door 51 of the refrigerator 5 will be opened when people take out items. When it is opened, the cold air in the refrigerator 5 will intersect with the hot air outside the refrigerator 5, which will cause the temperature inside the refrigerator 5 to drop, which will not only increase the energy consumption of the refrigerator 5 itself, but also cause the preservation effect to decrease and accelerate the spoilage of food inside the refrigerator 5. In the prior art, an air curtain is usually arranged on one side of the refrigeration door of the refrigerator 5. When the switch door 51 is opened, an air curtain is formed at the opening of the refrigeration door, thereby isolating the refrigerator 5 from the cold and hot interaction between the outside world, which can better avoid the temperature inside the refrigerator 5. degree loss; as shown in the attached drawings, an air duct is arranged inside the refrigerator 5, and a fan is arranged at the bottom of the air duct. The fan pumps the cold air at the bottom to the nozzle position, and then forms an air curtain through the action of the nozzle; however, it can be seen from the attached drawings and the patent document that the air duct is arranged inside the refrigerator 5, and extends from the inner side of the refrigerator 5 compartment to the top, which not only occupies the space inside the refrigerator 5 compartment, but also causes additional energy consumption; generally, the air outlet of the refrigerator 5 compartment is arranged on the inner wall of the refrigerator 5 compartment, and the arrangement of the above-mentioned air duct will also affect the air output of the air outlet, thereby affecting the temperature inside the refrigerator 5 compartment.

[0041] In view of the shortcomings of the prior art, this embodiment provides a refrigerator with an air curtain structure and a control method thereof, which can be specifically referred to as follows:

[0042] As attached Figure 1 , Attachment Figure 2 and attached Figure 3As shown, a refrigerator with an air curtain structure includes a steering body 1, a first opening 2, a second opening 3 and a steering assembly 4, the refrigerator 5 includes an inner shell, an outer shell and a switch door 51, a gap is provided between the inner shell and the outer shell for arranging foam glue or electronic components, etc., a refrigeration door or a freezing door is provided on one side of the outer shell and the inner shell, and the switch door 51 is rotatably provided on the outer shell and is used to close the refrigeration door or the freezing door; the steering body 1 is provided on the top of the inner shell of the refrigerator 5, that is, the steering body 1 is located between the inner shell and the outer shell of the refrigerator 5, a channel is provided inside the steering body 1, and one end of the channel is connected to the air duct of the refrigerator 5, and the cold air in the air duct of the refrigerator 5 will flow to the inside of the steering body 1; the first opening 2 and the second opening 3 are provided at the bottom of the steering body 1, and the first opening 2 is located at the refrigerator 5. In the middle of the compartment, the second opening 3 is located at one end close to the switch door 51 of the refrigerator 5, and two slots are provided on the top of the inner shell of the refrigerator 5, the two slots are respectively located in the middle of the compartment of the refrigerator 5 and close to the switch door 51, and the two slots correspond to the first opening 2 and the second opening 3, respectively, so as to facilitate the cold air in the steering body 1 to enter the compartment of the refrigerator 5 through the first opening 2 and the second opening 3; a steering assembly 4 is also provided inside the steering body 1, the steering assembly 4 cooperates with the channel in the steering body 1 and the first opening 2, the steering assembly 4 is located between the first opening 2 and the second opening 3, and the first opening 2 and the second opening 3 can be shielded by the steering assembly 4, so that the first opening 2 and the second opening 3 can be opened alternately, so as to realize the control of the temperature in the compartment of the refrigerator 5;

[0043] By arranging a steering body 1 on the top of the inner shell of the refrigerator 5 and connecting it with the air duct in the refrigerator 5, not only does it not occupy the space in the refrigerator 5 room, but also can reduce energy consumption by utilizing the effect of the cold air in the air duct; at the same time, a first opening 2 and a second opening 3 are opened at the bottom of the steering body 1, and in conjunction with a steering assembly 4, the first opening 2 and the second opening 3 can be opened alternately, thereby realizing the temperature control inside the refrigerator 5 room.

[0044] In the initial state, if attached Figure 5As shown, the switch door 51 of the refrigerator 5 is in a closed state, at this time, the steering assembly 4 cooperates with the second opening 3 and blocks the second opening 3, while the first opening 2 is in an open state, and under the action of the internal air duct of the refrigerator 5, cold air is sprayed from the first opening 2 to the interior of the refrigerator 5 through the channel in the steering body 1, and the food in the interior of the refrigerator 5 is kept fresh and refrigerated; when it is necessary to take food out of the interior of the refrigerator 5, the switch door 51 can be opened, and at this time, the internal equipment of the refrigerator 5 will detect that the switch door 51 of the refrigerator 5 is opened, and at the same time send a signal to the steering assembly 4, start the steering assembly 4 and make the steering The component 4 cooperates with the first opening 2 to block the first opening 2 and open the second opening 3. At this time, the cold air in the channel of the main body 1 will flow along the main body channel to the second opening 3 and be ejected at the second opening 3. The second opening 3 is vertically downward, so that the ejected cold air forms an air curtain, and the air curtain is located at the opening of the compartment of the refrigerator 5. The air curtain can effectively prevent the cold air in the refrigerator 5 from interacting with the hot air outside the refrigerator 5, thereby preventing the cold air in the refrigerator 5 from being lost. Due to the closure of the first opening 2, a certain pressure is also provided for the cold air ejected from the second opening 3, so that a wind curtain can be formed (as shown in the attached Figure 1 shown);

[0045] When the food in the refrigerator 5 room is taken away, the switch door 51 will be closed manually to close the refrigerator 5 room. When the switch door 51 of the refrigerator 5 is closed, the detection device in the refrigerator 5 will detect that the switch door 51 is closed and send a signal to the controller. The controller sends a signal to the steering component 4, the steering component 4 starts and cooperates with the second opening 3. At this time, the first opening 2 is opened and the second opening 3 is blocked. The cold air in the channel of the steering body 1 will flow into the refrigerator 5 room through the second opening 3. Since the second opening 3 is located in the middle of the refrigerator 5 room, the temperature in the refrigerator 5 room can be better controlled, and the temperature at various positions in the refrigerator 5 room can be quickly reduced.

[0046] As attached Figure 2 and attached Figure 3 As shown, the positions of the first opening 2 and the second opening 3 are different. The first opening 2 is set in the middle of the compartment of the refrigerator 5. Cold air is sprayed through the first opening 2 and can quickly reach various positions in the compartment of the refrigerator 5, so that the temperature in the refrigerator 5 is quickly reduced to achieve the effect of preserving food. The second opening 3 is set on a side close to the switch door 51 of the refrigerator 5, which can be used to form an air curtain to avoid temperature loss in the refrigerator 5. The first opening 2 and the second opening 3 are opened alternately with the opening and closing of the switch door 51, so that the temperature in the refrigerator 5 can be better controlled to ensure the freshness of food in the refrigerator 5.

[0047] In one embodiment of the present application, the steering assembly 4 includes a steering flap 41 and a driving assembly. The steering flap 41 is rotatably arranged inside the steering body 1, and the steering flap 41 is located between the first opening 2 and the second opening 3 to facilitate the steering flap 41 to cooperate with the first opening 2 and the second opening 3. The steering flap 41 is in the shape of an elongated strip, and the two ends of the steering flap 41 are abutted against the two sides of the channel of the steering body 1, and are slidingly sealed. The width of the steering flap 41 (the distance from the rotating end of the steering flap 41 to the other end) is the same as the height of the channel of the steering body 1; a driving assembly is arranged on the outside of the steering body 1, and the driving assembly is located between the inner shell of the refrigerator 5 and the outer shell of the refrigerator 5, and the driving assembly is connected to the rotating shaft of the steering flap 41, and the first opening 2 or the second opening 3 can be blocked or opened by driving the steering flap 41.

[0048] Specifically, in the initial state, the steering flap 41 cooperates with the channel in the steering body 1 to block the second opening 3, that is, the steering flap 41 is arranged perpendicularly to the length direction of the channel in the steering body 1, and the steering body 1 is horizontally arranged on the top of the inner shell of the refrigerator 5, the bottom wall of the steering flap 41 abuts against the bottom wall of the channel of the steering body 1, and the top wall of the steering flap 41 abuts against the top wall of the channel of the steering body 1, thereby cutting off the channel of the steering body 1, so that the cold air in the channel of the steering body 1 will not flow to the second opening 3, and under the action of the steering flap 41, the cold air flows into the compartment of the refrigerator 5 through the first opening 2, and is used for fresh-keeping and refrigeration in the compartment of the refrigerator 5;

[0049] When the switch door 51 of the refrigerator 5 is opened, the driving assembly is started, driving the steering flap 41 to rotate 90 degrees, so that the steering flap 41 is in a horizontal state and is arranged parallel to the channel in the steering body 1 to block the first opening 2, and open the channel of the steering body 1, so that the cold air in the air duct of the refrigerator 5 can flow to the second opening 3 through the channel of the steering body 1, and be ejected at the second opening 3 to form a wind curtain.

[0050] In this embodiment, the steering body 1 is a rectangular parallelepiped, and the channel inside it is also a rectangular parallelepiped. The width of the steering body 1 is smaller than the width of the top of the inner shell of the refrigerator 5, so that a driving assembly can be set on one side of the steering body 1, and the position where the second opening 3 is set on the steering body 1 is conical, and the width of the second opening 3 is the same as the width of the inner shell of the refrigerator 5, so that when the air curtain is sprayed out from the second opening 3, it can achieve the purpose of matching with the inner wall of the refrigerator 5 compartment, so as to avoid the temperature in the refrigerator 5 compartment from being lost between the air curtain and the inner wall of the refrigerator 5 compartment.

[0051] In this embodiment, the driving assembly includes a driving motor, which is arranged on the outer wall of the steering body 1. The driving motor is electrically connected to the controller in the refrigerator 5. The output shaft of the driving motor is coaxially connected to the rotating shaft of the steering flap 41. The steering flap 41 can be driven to rotate by the rotation of the driving motor; specifically, when the switch door 51 is opened, the driving motor is started and rotated forward, and the driving motor drives the steering flap 41 to rotate 90 degrees and is parallel to the bottom wall of the channel in the steering body 1, and the first opening 2 is blocked; when the switch door 51 is closed, the driving motor is started and reversed, and the driving motor drives the steering flap 41 to rotate in the opposite direction, that is, to restore the initial state, the steering flap 41 is vertical to the bottom wall of the channel of the steering body 1, and the channel of the steering body 1 is blocked and cut off. At this time, the first opening 2 is opened and the second opening 3 is blocked.

[0052] In this embodiment, the driving component can also be a pull rope and a torsion spring. The switch door 51 is rotatably set on the outer shell of the refrigerator 5, and a rotating shaft is set on the switch door 51. One end of the pull rope is wound and connected with the rotating shaft of the switch door 51 of the refrigerator 5, and the other end is wound and connected with the rotating shaft of the steering flap 41. Although the rotating shaft of the switch door 51 is in a vertical state and the rotating shaft of the steering flap 41 is in a horizontal state, the pull rope can connect the two through its own characteristics; a torsion spring is also set on the rotating shaft of the steering flap 41, one end of the torsion spring is supported by the inner wall of the outer shell of the refrigerator 5, and the other end is supported by the outer wall of the inner shell of the refrigerator 5.

[0053] In the initial state, one end of the torsion spring is supported against the inner wall of the outer shell of the refrigerator 5, and the other end is supported against the outer wall of the inner shell of the refrigerator 5. At this time, the steering flap 41 blocks the second opening 3. When the switch door 51 is opened, the rotating shaft of the switch door 51 is wound around the pull rope, and the pull rope on the rotating shaft of the steering flap 41 is pulled to rotate, thereby driving the steering flap 41 to rotate, blocking the first opening 2 and opening the second opening 3. At this time, the torsion spring is in a compressed state; when the switch door 51 is closed, the rotating shaft of the switch door 51 relaxes the pull rope, and the steering flap 41 rotates in the opposite direction under the action of the torsion spring, and while rotating, the pull rope is wound, so that the torsion spring, the steering flap 41 and the pull rope are restored to the initial state.

[0054] In this embodiment, the driving assembly includes not only the above two modes, but also other driving modes, such as gear matching transmission, chain transmission or cylinder drive.

[0055] In one embodiment of the present application, as shown in the attached Figure 4As shown, one end of the steering body 1 close to the switch door 51 of the refrigerator 5 is arc-shaped, and the second opening 3 is arranged at the bottom of the arc position of the rotating flap; the steering body 1 includes a horizontal portion and a turning portion, the horizontal portion is arranged at one end close to the air duct of the refrigerator 5, and the turning portion is arranged at one end close to the switch door 51 of the refrigerator 5, and one side of the turning portion is arc-shaped, thereby forming an arc-shaped channel at one end inside the channel of the steering body 1, and the bottom of the arc-shaped channel is the second opening 3. Through the setting of the arc-shaped channel, the cold air in the steering body 1 can flow to the second opening 3 better, avoiding the formation of damping at the turning point, resulting in the height and width of the formed wind curtain being insufficient to cover the opening of the refrigerator 5 compartment.

[0056] In this embodiment, rounded corners are provided at both ends of the steering flip, and the upper and lower ends of the steering flap 41 are respectively abutted against the upper and lower side walls of the channel in the steering body 1 and slide together. By providing rounded corners at both ends of the steering flap 41, the steering flap 41 can be better rotated to avoid the steering flap 41 being unable to rotate due to the side wall of the steering flap 41 abutting against the inner wall of the channel of the steering body 1.

[0057] In this embodiment, the steering flap 41 is made of rubber material. The rubber material has a certain degree of softness and can undergo elastic deformation, and can better seal the contact position between the steering flap 41 and the inner wall of the inner channel of the steering body 1.

[0058] In one embodiment of the present application, as shown in the attached Figure 2 and attached Figure 4 As shown, the interior of the steering body 1 is provided with a first air outlet 11 and a second air outlet 12, the first air outlet 11 and the second air outlet 12 are in a connected state, the height of the second air outlet 12 is greater than the height of the first air outlet 11, and the steering flap 41 is rotatably arranged in the second air outlet 12, the first opening 2 and the second opening 3 are both arranged in the second air outlet 12, the first opening 2 is located on a side of the second air outlet 12 close to the first air outlet 11, and the steering flap 41 is located on one side of the first opening 2, and through the action of the driving component, the steering flap 41 can cover the first opening 2 or cooperate with the inner wall of the second air outlet 12 to cover the second opening 3;

[0059] By making the height of the first air outlet 11 smaller than that of the second air outlet 12, and the top walls of the first air outlet 11 and the second air outlet 12 are in the same plane, and the bottom wall of the second air outlet 12 is lower than the bottom wall of the first air outlet 11, when the turning flap 41 blocks the first opening 2, the side wall of the turning flap 41 abuts against the bottom wall of the second air outlet 12, and the turning flap 41 is located at the bottom of the bottom wall of the first air outlet 11. When the first air outlet 11 supplies air to the second air outlet 12, the turning flap 41 will not block the first air outlet 11 from supplying air due to protruding from the bottom wall of the first air outlet 11, thereby effectively improving the efficiency of forming the wind curtain.

[0060] In this embodiment, the turning flap 41 cooperates with the first opening 2, and the side wall of the turning flap 41 and the inner bottom wall of the first air outlet 11 are in the same horizontal plane; that is, after the turning flap 41 is flipped over, the top wall of the turning flap 41 and the bottom wall of the first air outlet 11 are in the same horizontal plane, which not only avoids blocking the wind in the first air outlet 11, but also provides a certain guiding effect.

[0061] As attached Figure 6 As shown, the present application also provides a refrigerator control method, based on the above-mentioned refrigerator with an air curtain structure, further comprising the following steps:

[0062] S100, when the refrigerator door is opened, the steering assembly is synchronously started to cover the first opening through the steering assembly and open the second opening;

[0063] A sensing component is generally provided at the opening of the inner shell of the refrigerator 5 for sensing whether the switch door 51 is in an open or closed state. By detecting the state of the switch door 51 through the sensing component, the controller in the refrigerator 5 can control the steering component 4 and cover or open the first opening 2 and the second opening 3.

[0064] S200, when the refrigerator door is closed, the steering assembly is synchronously started to open the first opening and cover the second opening through the steering assembly.

[0065] When the switch door 51 of the refrigerator 5 is closed, the sensor component in the refrigerator 5 detects the door closing action and sends a signal to the controller. The controller sends a signal to the steering component 4, and the steering component 4 starts to open the first opening 2 and cover the second opening 3.
