Detailed implementation manners

[0028] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with embodiments.

[0029] As Figures 1-6 shown, according to an embodiment of the present invention, a refrigerator is provided, which includes a refrigerator housing 10 and an air outlet part. There is at least one refrigerator compartment 11 inside the refrigerator housing 10. An air outlet 12 is provided on the inner wall of the refrigerator housing 10, and the air outlet 12 corresponds to at least one refrigerator compartment 11; the air outlet part includes an air outlet baffle 21, and the air outlet baffle 21 is rotatably arranged at the air outlet 12 and rotates to a corresponding angle according to the wind speed of the cooling air to control the outflow direction of the cooling air.

[0030] The refrigerator of this embodiment is provided with a corresponding air outlet 12 at the refrigerator compartment 11 to blow cooling air into the refrigerator compartment 11 and reduce the temperature inside the refrigerator compartment 11. Since the air outlet part is provided at the air outlet 12, by controlling the wind speed of the cooling air, the air outlet baffle 21 of the air outlet part can be adjusted to rotate to different angles, thereby adjusting the outflow direction of the cooling air, so as to realize blowing air to the position with a higher temperature inside the refrigerator compartment 11 as needed, thereby quickly reducing the temperature at this position and improving the temperature uniformity and refrigeration speed inside the refrigerator compartment 11.

[0031] In this embodiment, the air outlet baffle 21 is made of a material with ultra-light weight and good cold resistance. This enables the air outlet baffle 21 to rotate driven by the refrigerated air. By controlling the wind speed of the refrigerated air, the air outlet baffle 21 can be rotated to different angles to control the air outlet direction of the air outlet. Since the air outlet baffle 21 rotates by the push of the refrigerated air and the rotation angle corresponds to the flow rate of the cooler, no motor is required as the power source, reducing the production cost.

[0032] In this embodiment, the air outlet baffle 21 is rotatably arranged at the air outlet 12 around the first axis. For example, the first axis is a horizontal axis.

[0033] The air outlet baffle 21 can be a rectangular baffle or a baffle of any other appropriate shape. Its quantity can be determined according to needs.

[0034] Optionally, to facilitate the installation of the air outlet baffle 21 and make the air outlet baffle 21 rotate more smoothly around the air outlet 12, the air outlet part further includes a first rotating shaft assembly 22. The first rotating shaft assembly 22 is rotatably arranged on the refrigerator housing 10 and is located at the air outlet 12, and the air outlet baffle 21 is arranged on the first rotating shaft assembly 22.

[0035] Of course, in other embodiments, the air outlet baffle 21 can be arranged at the air outlet through other structures. For example, it can be directly connected to the inner wall of the refrigerator through structures such as protrusions.

[0036] Optionally, to make the air outlet baffle 21 rotate more easily and thus more accurately control the rotation angle of the air outlet baffle 21, the first rotating shaft assembly 22 includes a first mounting shaft 221 and a stop ball 222. Stop balls 222 are arranged at both ends of the first mounting shaft 221. The air outlet baffle 21 is arranged on the first mounting shaft 221. An installation space 111 is arranged on the inner wall of the refrigerator housing 10. The stop ball 222 is movably arranged in the installation space 111, and there is a gap between the stop ball 222 and the inner wall of the installation space 111.

[0037] As Figure 4 shown, an installation space 111 is arranged on the inner wall of the refrigerator. In this embodiment, the installation space 111 is a spherical space. Of course, in other embodiments, the installation space 111 can be a space of other shapes, such as a cube, etc. The stop ball 222 is arranged in the installation space 111. In this way, when the air outlet baffle 21 is pushed by the refrigerated air, due to the spherical surface fit between the stop ball 222 and the installation space 111, the air outlet baffle 21 rotates.

[0038] In the normal state, the air outlet baffle 21 is in a vertical state, covering at least part of the air outlet 12. When it is necessary to blow air into the refrigerator compartment 11, the refrigerated air is used to push the air outlet baffle 21 to rotate, thereby opening the air outlet and controlling the refrigerated air to blow in the required direction.

[0039] Optionally, to facilitate controlling the rotational resistance as needed, the air outlet portion further includes a stop rod 23 that cooperates with the stop ball 222 to control the rotational resistance of the first mounting shaft 221. The stop rod 23 is movably disposed on the refrigerator housing 10, and the length of the stop rod 23 extending into the mounting space 111 is adjustable.

[0040] In this way, the stop rod 23 extends into the mounting space 111 and presses the stop ball 222 against the wall surface of the mounting space 111. By adjusting the length of the stop rod 23 extending into the mounting space 111, the pressing force between the stop ball 222 and the wall surface of the mounting space 111 can be adjusted, that is, the resistance to the rotation of the air outlet baffle 21.

[0041] Optionally, in a feasible implementation, to facilitate adjusting the stop rod 23, a threaded hole is provided on the refrigerator housing 10. The stop rod 23 is movably disposed on the refrigerator housing 10 through the threaded hole, and a knob 24 connected to the stop rod 23 and driving the stop rod 23 to rotate is provided on the outer wall of the refrigerator housing 10.

[0042] In this way, by providing the knob 24, the user can conveniently rotate the stop rod 23 externally, so that the stop rod 23 screws in or out to adjust the length extending into the mounting space 111, thereby adjusting the resistance to the rotation of the air outlet baffle 21.

[0043] Specifically, by screwing the stop rod 23, the length of the stop rod 23 inserted into the mounting space 111 is increased or decreased. The more the stop rod 23 is screwed, the more it is inserted. Since the spherical space of the inner wall is limited, the movable space of the stop ball 222 becomes smaller, so that the first mounting shaft 221 connected to the stop ball 222 requires a greater torque to rotate. Therefore, under the condition of the same air outlet speed, the rotation angle of the air outlet baffle 21 will decrease.

[0044] The design of this first rotating assembly can meet the working conditions of the refrigerator with a fixed wind speed for a long time, and can also change the flow direction of the cold air flow to improve the uniformity of the temperature distribution in the refrigerator compartment and the cooling speed of the required area.

[0045] Optionally, in another feasible implementation, to improve the automation, a threaded hole is provided on the refrigerator housing 10. The stop rod 23 is movably disposed on the refrigerator housing 10 through the threaded hole, and an electric driving member is further provided in the refrigerator housing 10. The electric driving member is connected to the stop rod and drives the stop rod 23 to rotate.

[0046] In this way, the extending length of the stop rod 23 can be automatically controlled by the electric driving member (such as a motor), thereby controlling the resistance to the rotation of the air outlet baffle 21. In addition, the control by using the electric driving member can be remotely controlled, so that the adaptability and convenience are better.

[0047] Optionally, the air outlet part further includes a wind deflector rotatably arranged at the air outlet 12 around the second axis. The wind deflector is pushed by the cold air to rotate, so as to control the outflow direction of the cold air.

[0048] Wherein, the first axis can be a horizontal axis, and the second axis can be a vertical axis. In this way, the air outlet direction can be adjusted in multiple dimensions through the air outlet baffle 21 and the wind deflector 41, so that the cold air can be more evenly distributed in each space of the refrigerator compartment 11.

[0049] Optionally, in order to enable the wind deflector 41 to rotate smoothly and reduce wear, the air outlet part further includes a second rotating assembly. The second rotating assembly is rotatably arranged on the inner wall of the refrigerator housing 10 around the second axis, and the wind deflector 41 is arranged on the second rotating assembly.

[0050] The second rotating assembly can be any appropriate structure. For example, the second rotating assembly can include a second mounting shaft 42. The wind deflector 41 is rotatably arranged on the inner wall of the refrigerator housing 10 through the second mounting shaft 42, and the rotation axis of the second mounting shaft 42 is the second axis. The second axis is perpendicular to the first axis, and the second axis is located in front of or behind the first axis to prevent interference. Or the second rotating assembly can also adopt other structures.

[0051] In this embodiment, the second mounting shaft 42 is located behind the first mounting shaft, and the wind deflector 41 is divided into two pieces with the first mounting shaft as the center to achieve the purpose of rotation.

[0052] Optionally, in order to more timely and accurately determine the position in the refrigerator compartment 11 that needs to be cooled down, the refrigerator further includes a temperature sensor 30. The temperature sensor 30 is arranged in the refrigerator compartment 11 and detects the temperature at the location where it is located.

[0053] For example, as Figure 5 and Figure 6 shown, temperature sensors 30 can be arranged both in the upper part and the lower part of the refrigerator compartment 11 to respectively detect the temperatures in the upper part and the lower part of the refrigerator compartment 11. In this way, the wind speed of the cold air can be controlled according to the temperature detected at the location where the temperature sensor 30 is located, and the air outlet baffle 21 is rotated to the angle with the opening facing the position that needs to be adjusted, so that the cold air is blown towards the position that needs to be adjusted.

[0054] Optionally, in order to improve the intelligence of the cold air delivery, the refrigerator further includes an air supply member for delivering the cold air. The air supply member is connected to the air outlet 12 through an air duct. The air supply member controls the wind speed of the cold air according to the temperature detected by the temperature sensor 30, so as to control the rotation angle of the air outlet baffle 21 and make the air outlet direction face the position where the temperature sensor is located.

[0055] The air supply component can be a blower, etc., such as a variable-frequency blower. The blower is connected to the controller, and the controller controls the rotational speed of the blower according to the temperature detected by the temperature sensor 30, thereby controlling the wind speed of the refrigerated air output by the blower, so that the refrigerated air can push the air outlet baffle 21 to rotate to a suitable angle and blow air towards the required position.

[0056] As Figure 5 shown, when the temperature sensor 30 detects that the temperature in the upper space of the refrigerator compartment 11 is relatively high and needs to be cooled down, it feeds back the information that the air outlet wind speed needs to be adjusted. At this time, the wind speed is adjusted to the state where the air outlet baffle 21 faces upward. Subsequently, the refrigerated air, as Figure 5 shown, changes its flow direction to blow upward, thereby realizing the temperature adjustment of the required area and improving the cooling speed of this area and the temperature uniformity of the compartment space.

[0057] Figure 6 The process of cooling the middle and lower regions of the refrigerator compartment 11 is similar, so it will not be elaborated here.

[0058] It should be noted that the corresponding relationship between the rotation angle of the air outlet baffle 21 and the wind speed can be determined in advance according to experimental detection.

[0059] A return air outlet 13 is also provided on the inner wall of the refrigerator to ensure the circulation of the gas in the refrigerator compartment 11.

[0060] By setting the air outlet part, the temperature space uniformity in the refrigerator compartment 11 can be improved, and the cooling speed of the required area can be increased. In summary, by setting a lightweight air outlet baffle 21 at the air outlet, a weak refrigerated air can blow the air outlet baffle 21 to rotate 360° around the first installation axis. Different air outlet wind speeds correspond to different opening and closing angles of the air outlet baffle 21. Different opening and closing angles of the air outlet baffle 21 can change the flow direction of the refrigerated air at the air outlet. At different angles of the air outlet baffle 21, temperature sensors 30 are arranged in the areas where the refrigerated air flows to detect the temperature of this area. When the temperature in a certain area of the refrigerator compartment 11 is higher than other areas, the air outlet wind speed is changed, and the air outlet angle of the air outlet baffle 21 is adjusted, so that the cold air flow blows towards this area for cooling, thereby improving the space temperature uniformity in the refrigerator compartment 11 and quickly cooling the required area.

[0061] The refrigerator according to the present invention has the following technical effects:

[0062] By detecting the regional temperature with a temperature sensor, the rotation of the air outlet baffle changes the flow direction of the refrigerated air at the air outlet, actively cools the required area, and improves the uniformity of the space temperature distribution and the regional cooling speed. The air outlet baffle rotates depending on the flow rate of the refrigerated air, without the need to set up a motor, reducing the occupation of the inner wall space of the refrigerator by the motor. Under the same wind speed, when adjusting the tightness of the adjusting rod, the air outlet angle of the air outlet baffle can be controlled, improving the functionality of the air outlet part.

[0063] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, various modifications and variations can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
