DETAILED DESCRIPTION

[0024] For reference Figures 1 to 7 ​​As shown, according to the embodiment of the present application, an air outlet assembly is provided, which comprises an air guide frame 1 and an air guide cover 2, the air guide cover 2 is in a semi-hemispherical circular truncated cone shape, and the top surface of the semi-hemispherical circular truncated cone shape is provided with an air outlet 21, the air guide frame 1 is provided with an annular body 11, which is used to surround the axial flow fan 100 provided in the air conditioner indoor unit, the air guide cover 2 is provided with a flat state in which the axis of the annular body 11 coincides with the axis of the air guide cover 2, and a deflection state in which the air guide cover 2 is at a target angle with the axial direction of the air guide cover 2, the first end of the annular body 11 towards the air guide cover 2 is provided with a convex ring 12 extending to the outside of the annular body 11, and the free end edge of the convex ring 12 is connected with the inner wall of the air guide cover 2 in the flat state and the deflection state of the air guide cover 2. The semi-hemispherical circular truncated cone shape is different from the conventional circular truncated cone shape in that the side surface of the semi-hemispherical circular truncated cone shape is a spherical surface. In this technical solution, the air guide frame 1 is arranged in the space between the air guide cover 2 and the axial flow fan 100 to realize the nearly seamless connection between the air guide cover 2 and the air guide frame 1, which can not interfere with the deflection movement of the semi-hemispherical circular truncated cone-shaped air guide cover 2, so that the airflow blown out by the axial flow fan 100 can be smoothly guided to the air guide cover 2 to be blown out from the air outlet 21, which can significantly improve the air supply distance, and the annular body 11 arranged around the axial flow fan 100 can rectify the air outlet to reduce the noise during the operation of the fan. The aforementioned nearly seamless refers to the necessary gap between the state change of the air guide cover 2 and the edge of the convex ring 12 of the air guide frame 1.

[0025] In some embodiments, the first end of the air guide frame 1 is located in the air guide cover 2, the air guide cover 2 is rotatably connected between the outer wall of the annular body 11 and the two rotating structures arranged on the symmetrical two sides of the air guide cover 2, and the rotating axes of the two rotating structures are coaxial and pass through the spherical center of the hemispherical side surface of the semi-hemispherical circular truncated cone shape, so as to maximize the swing angle of the state switching of the air guide cover 2, and in one embodiment, in order to limit the maximum swing range of the air guide cover 2, the end edge of the air guide cover 2 towards the air guide frame 1 is provided with an inwardly extending protrusion (not shown in the figure), which can be matched with the aforementioned convex ring 12 to stop the further swing of the air guide cover 2 when it swings to the preset maximum position, thereby preventing the air guide gap between the air guide frame 1 and the air guide cover 2 from leaking air.

[0026] As shown in Figure 1 and Figure 2 the second end of the annular body 11 is provided with a plurality of fixed connection feet 13, which are arranged at intervals along the circumferential direction of the annular body 11, so as to be connected as a whole with the corresponding fixed components through the fixed connection feet 13, and in a specific embodiment, the aforementioned fixed components are, for example, a motor support 101, which is also a fixed mounting structure of the driving motor provided in the axial flow fan 100.

[0027] Continuing to refer toFigure 1 As shown, the rotating structure is configured by a receiving cavity 31 on the outer wall of the annular main body 11, a shaft sleeve 32 received in the receiving cavity 31, and a rotating cover plate 33 rotatably connected with the shaft sleeve 32, and the rotating cover plate 33 is also fixedly connected with the air deflector 2. In this technical solution, the rotating structure formed by the receiving cavity 31, the shaft sleeve 32, and the rotating cover plate 33 forms a rotatable connection between the air deflector 2 and the air deflector frame 1, which is simple and reliable. In a specific embodiment, the rotating cover plate 33 includes a plate body 331 and a rotating shaft 332 connected to one side of the plate body 331, the rotating shaft 332 is inserted into the central through hole of the shaft sleeve 32, and the plate body 331 is connected with the mounting portion of the air deflector 2. As a preferred solution, the plate body 331 is detachably connected to the outer side wall of the air deflector 2, so as to block the shaft sleeve 32 in the receiving cavity 31. The rotating cover plate 33 not only has a rotating connection function, but also has a dustproof function, and the structure is further simplified.

[0028] One of the two rotating structures further includes a rotating motor 34 fixedly connected and received in the corresponding receiving cavity 31, and the output shaft of the rotating motor 34 is sleeved with the rotating shaft 332. The setting of the rotating motor 34 can make the state switching of the air deflector 2 automatic, and improve the user experience comfort. Specifically, the rotating motor 34 can be controlled by the main control component of the air conditioner, which adjusts the rotation direction and rotation angle of the rotating motor 34 according to the specific operation mode of the air conditioner.

[0029] A corresponding air guiding component can also be arranged in the air outlet 21, for example, an air guiding grille 4 is arranged in the air outlet 21 to guide the air flow of the air outlet 21 at a necessary air supply angle. Preferably, the air guiding grille 4 is integrally formed with the air deflector 2, which can be assembled without, thereby reducing the manufacturing cost and the failure probability (without setting a swing driving motor). The air outlet 21 is a circular air outlet. When the air deflector 2 is in a flat state, the air guiding direction of the air guiding grille 4 is parallel to the axis of the annular main body 11, that is, the grille entity of the air guiding grille 4 is always perpendicular to the air outlet 21, which can ensure that the air supply direction is changed with little loss of wind speed and air volume, and the scientific air guiding effect is achieved.

[0030] According to the embodiment of the present application, a cabinet type air conditioner is also provided, which includes an air outlet assembly 400, that is, the above-mentioned air outlet assembly. Specifically, see Figure 3 and Figure 4As shown, the cabinet air conditioner further comprises a cabinet shell, at least two axial flow fans 100 are arranged in the cabinet shell in a height direction of the cabinet shell, and each axial flow fan 100 is correspondingly provided with a set of air outlet assemblies. It can be understood that the at least two axial flow fans 100 are arranged on the air outlet side of the heat exchanger 301, and the axial flow fan 100 is used to drive the airflow, and the air inlet and the air outlet are relatively short, so that the air supply efficiency is higher. In the technical solution, the at least two axial flow fans 100 arranged in the height direction can realize the layered distribution of the air outlet airflow in the height direction and a larger air supply range. Specifically, as shown in Figure 4 As shown, the cabinet shell comprises a rear plate assembly 201 and a panel 202 buckled with the rear plate assembly 201, the panel 202 is provided with an air outlet through hole 203 capable of accommodating the air guide cover 2, and the at least two axial flow fans 100 are fixedly assembled on the motor support 101. The second end of the air guide frame 1 is fixed on the motor support 101. In this way, the air guide cover 2 in the present application is not assembled and connected with the panel 202, and the panel 202 only exists as a clearance fit component of the air guide cover 2, facilitating the disassembly and assembly of the panel 202. At the same time, since the air guide cover 2 is a hemispherical circular truncated cone, the gap between the air guide cover 2 and the hole wall of the air outlet through hole 203 will not change with the state of the air guide cover 2, thereby ensuring the appearance aesthetics of the air conditioner.

[0031] Figure 5 As shown in the middle, the air guide cover 2 in the upper and lower air outlet assemblies is in a flat state; Figure 6 As shown in the middle, the air guide cover 2 in the upper and lower air outlet assemblies is in a flat state; Figure 7 As shown in the middle, the air guide cover 2 in the upper and lower air outlet assemblies is in a flat state; Specifically, the air conditioner of the present application can realize various air supply modes through function control. When directional air supply is realized, in combination with the air outlet assembly 400 and the rotation speed of the double axial flow fans, the orientation of the upper and lower air guide covers 2 is controlled to realize various air guide modes. For example, in the heating mode, the upper and lower air outlets are both downward ( Figure 6 ), so that the hot air is scientifically heated from bottom to top; for example, in the cooling mode, the upper air outlet is directed to air guide, the lower air outlet is directed downward, and the lower fan is at low speed ( Figure 7 ), so as to avoid blowing cold air and deliver cold air from top to bottom, so as to quickly adjust the indoor air temperature, reduce the indoor temperature difference, and improve the comfort of the user.

[0032] It is easy for those skilled in the art to understand that the advantageous technical features of the above-mentioned modes can be freely combined and superimposed without conflict.

[0033] The above merely describes the preferred embodiments of the present application, but should not be used to limit the present application, and any modification, equivalent replacement, and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
