In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any appropriate manner in any one or more embodiments or examples.

[0038] Figure 1 This is a schematic structural diagram of an air outlet assembly according to an embodiment of the present invention, as shown in FIG. Figure 1 As shown, and reference Figures 2 to 4 An embodiment of the present invention provides an air outlet assembly for an air conditioner, comprising an air outlet 11 for air flow to pass through and an air guide device. The air guide device has an air guide plate 20 rotatably mounted at the air outlet 11. The air guide plate 20 has an initial position, that is, the air guide plate 20 has an initial position relative to the air outlet 11, and the initial position is generally the position of the air guide plate 20 when the air conditioner is not working. For example, in some embodiments, when the air guide plate 20 is in the initial position, the air guide plate 20 is preferably configured to block the air outlet 11. In other embodiments, the air guide plate 20 may also be in other positions and is not necessarily used to block the air outlet 11.

[0039] The air deflector device has and / or generates a restoring force to urge the air deflector 20 to rotate toward its initial position when the air deflector 20 moves away from its initial position, thereby urging the air deflector 20 to rotate toward its initial position. The air deflector 20 is configured to overcome the restoring force and move away from its initial position under the influence of airflow passing through the air outlet.

[0040] When the vent assembly of the present embodiment is in operation, when air flows through the vent, the airflow pushes the air deflector 20, overcoming the restoring force, causing the air deflector 20 to move, adjusting the angle of the air deflector 20 and, in turn, adjusting the ventilation level and the direction of airflow. Generally, the greater the force of the airflow, the greater the angle at which the air deflector 20 moves away from its initial position. Therefore, the angle of the air deflector 20 can be adjusted by adjusting the force of the airflow. When the airflow stops, the air deflector 20 returns to its initial position due to the restoring force.

[0041] In the air outlet assembly of the air conditioner according to the embodiment of the utility model, since there is an air guide device, and the air guide device can have or generate a reset force to promote the air guide plate 20, the opening of the air guide plate 20 can be driven by the airflow. The greater the airflow force, the larger the opening angle of the air guide plate 20, and the reset force is used to close it. The opening and closing of the air guide plate 20 does not require a special drive device, and there is no need to set up a special installation space for the drive device, so that the structure is simple. Moreover, the opening and closing of the air guide plate 20 does not require the control of the drive device. The air guide plate 20 works naturally with the wind force, etc., and the control is simple. And using the airflow itself for control can make the air inlet or outlet at the air outlet more natural, giving the user a different air supply experience from the existing one, so that the user has a different perception and increases the user's preference.

[0042] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, in the initial position, the rotation axis of the wind deflector 20 is above the center of mass of the wind deflector 20, so that the gravity of the wind deflector 20 serves as the restoring force. For example, the wind deflector is provided with a rotating shaft 21, which is above the center of mass of the wind deflector 20. In this embodiment of the present invention, the wind deflector 20 is returned to its initial position by its own gravity. The weight of the wind deflector 20 can be adaptively designed according to actual needs.

[0043] In some embodiments of the present invention, Figure 2 As shown, the thickness of the lower end of the air deflector 20 is greater than the thickness of the upper end of the air deflector 20, and the rotation axis of the air deflector 20 is located at the upper end of the air deflector 20. For example, the thickness of the air deflector 20 gradually increases from top to bottom. The two side surfaces of the air deflector 20 are respectively a first side surface and a second side surface, and the first side surface and the second side surface are symmetrically arranged. The first side surface and the second side surface can both be flat, convex, or concave. The symmetrical arrangement of the first side surface and the second side surface allows the air outlet to either take in or out air.

[0044] In some embodiments of the present invention, the air deflector 20 may be configured as a hollow structure, and the mass of the lower end of the air deflector 20 is greater than the mass of the upper end of the air deflector 20 .

[0045] In other embodiments of the present invention, the two side surfaces of the air deflector 20 are respectively a first side surface and a second side surface. The first side surface is convex, and the second side surface is concave. In embodiments of the present invention, the air vent can be used for both air intake and air outlet. When the air vent is used for air intake, the concave surface is located in the airflow path of the air vent, which is more conducive to changing the outlet direction of the airflow and facilitating downward airflow. When the air vent is used for air intake, and the air conditioner is a ceiling air conditioner, the heat exchanger and the air vent are arranged correspondingly. The convex surface facilitates airflow to flow toward the upper side of the heat exchanger, facilitating airflow distribution over the heat exchanger and achieving better heat exchange with the heat exchanger. In other words, in embodiments of the present invention, since one side of the air deflector 20 is concave and the other side is convex, when the air vent is used as an air inlet, the convex surface facilitates heat exchange between the airflow and the heat exchanger inside the housing, improving heat exchange efficiency. When the air vent is used as an air outlet, the concave surface facilitates downward airflow, facilitating rapid cooling or heating of the indoor space and improving the speed of temperature adjustment.

[0046] In some embodiments of the present invention, the air deflector further includes a counterweight to provide a restoring force. The counterweight is mounted on the air deflector 20. In its initial position, the rotation axis of the air deflector 20 is above the counterweight. The counterweight can be mounted on the side of the air deflector 20 that is not used for air deflection, or two counterweights can be mounted at either end of the air deflector 20 to minimize impact on airflow.

[0047] In some alternative embodiments of the present invention, a counterweight is configured to be movable vertically and is in transmission connection with the air deflector 20. With this vertically movable counterweight, when the air deflector 20 moves away from its initial position, the counterweight moves upward, driven by the air deflector 20, and then moves downward, returning the air deflector 20 to its original position. In some embodiments of the present invention, a wire and a pulley may be provided between the counterweight and the air deflector 20. The wire passes over the pulley, with its ends connected to the air deflector 20 and the counterweight, respectively.

[0048] In some embodiments of the present invention, the air deflector further includes an elastic reset device connected to the air deflector 20 to generate a reset force when the air deflector 20 moves away from its initial position. The elastic reset device may be a torsion spring. The torsion spring is mounted on the rotating shaft of the air deflector 20. One end of the torsion spring is fixedly connected to the air deflector 20, and the other end is fixedly connected to the housing forming the air outlet. The torsion spring can return the air deflector 20 to its initial position regardless of whether the air deflector 20 is used for air intake or air discharge.

[0049] In some embodiments of the present invention, the wind guide device includes both an elastic reset device and a counterweight. In other embodiments of the present invention, the wind guide device includes both an elastic reset device and a counterweight, and in the initial position, the rotation axis of the wind guide plate 20 is on the upper side of the center of mass of the wind guide plate 20, so that the gravity of the wind guide plate 20 is the reset force. In still other embodiments of the present invention, the wind guide device includes an elastic reset device, and in the initial position, the rotation axis of the wind guide plate 20 is on the upper side of the center of mass of the wind guide plate 20, so that the gravity of the wind guide plate 20 is the reset force. In still other embodiments of the present invention, the wind guide device includes a counterweight, and in the initial position, the rotation axis of the wind guide plate 20 is on the upper side of the center of mass of the wind guide plate 20, so that the gravity of the wind guide plate 20 is the reset force.

[0050] In some embodiments of the present invention, Figure 1 As shown, there are multiple air guide plates 20, which are arranged in sequence along the vertical direction. In the initial position, the lower surface of the upper air guide plate 20 contacts the upper end of the lower air guide plate 20, or the distance between the lower surface of the upper air guide plate 20 and the upper end of the lower air guide plate 20 is within 5 mm, preferably 2 mm or 3 mm.

[0051] In some embodiments of the present invention, the lower surface of the air deflector 20 is a downwardly arched arc surface 22. The axis of the arc surface 22 can be the rotation axis of the air deflector 20. This facilitates the rotation of the air deflector 20 and prevents interference between the two air deflectors 20, especially when the upper air deflector 20 contacts the lower air deflector 20.

[0052] Figure 3 FIG. 1 is a schematic structural diagram of an indoor unit of an air conditioner according to an embodiment of the present invention. Figure 3 As shown, and reference Figure 4 The embodiment of the present invention further provides an indoor unit of an air conditioner, comprising a housing 10, a fan 40, an evaporator 30 and an air outlet assembly in any of the above embodiments, wherein the air outlet of the air outlet assembly is arranged on the housing 10. The air guide plate 20 is rotatably mounted on the housing 10. A connecting port is also provided on the housing 10. The evaporator 30 and the fan 40 are arranged in the housing 10. When the fan 40 is working, the air flow is prompted to enter the housing 10 through the air outlet, exchange heat with the evaporator 30, and then flow out from the connecting port. In other embodiments of the present invention, when the fan 40 is working, the air flow is prompted to enter the housing 10 through the connecting port, exchange heat with the evaporator 30, and then flow out from the air outlet. The air flow can drive the air guide plate 20 to rotate to adjust the wind direction.

[0053] In some embodiments of the present invention, the fan 40 is configured to controllably change the direction of air flow so that the airflow enters the housing 10 through the air vents, or flows out of the housing 10 through the air vents. In other words, the fan 40 is a bidirectional fan 40 that can adopt different airflow circulation modes at different stages, thereby making the indoor space adjustment more diverse and more in line with actual conditions.

[0054] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, there are multiple air outlet assemblies; the housing 10 includes a peripheral wall 12 and a bottom wall 13. The peripheral wall 12 is provided with multiple air outlets along the circumferential direction of the housing 10. The bottom wall 13 is provided with the above-mentioned communication port. A grille 14 can be provided at the communication port.

[0055] For example, the indoor unit of the air conditioner is a ceiling unit. The peripheral wall 12 includes a first peripheral wall portion, a second peripheral wall portion, a third peripheral wall portion and a fourth peripheral wall portion connected in sequence, and each of the first peripheral wall portion, the second peripheral wall portion, the third peripheral wall portion and the fourth peripheral wall portion has an air outlet assembly.

[0056] In the embodiment of the present invention, by setting the air inlet and outlet on different surfaces, the air inlet and outlet are distributed in different directions, and the heat exchange effect is high, which can solve the problem of low heat exchange efficiency of the air inlet and outlet on the same surface in the existing ceiling machine. In addition, in the ceiling machine of the present invention, there is only one connecting port on the bottom wall, that is, the panel, and there is no need to set the inlet and outlet at the same time, which facilitates the integration of the panel. The air outlet is set on the peripheral wall of the shell 10, and there is no need to set a downward air duct between the inner side of the shell 10 and the heat exchanger, and to set a driving device for driving the air guide plate 20, so that the distance between the shell 10 and the heat exchanger is reduced, so that the panel does not need to be set very large, saving space and cost. That is, the ceiling machine of the present invention can solve the problems of the current ceiling machine with complex structure, large space, high cost and low heat exchange efficiency, can reduce the overall volume of the machine, and thus reduce the cost of processing materials, simple structure, high reliability, low failure rate, and make the ceiling machine easy to install on site, saving manpower and material resources, and improving reliability.
