Any implementation described as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations. The following description is presented to enable any person skilled in the art to make and use the application. Details are set forth in the following description for purpose of explanation. It should be appreciated that one of ordinary skill in the art will readily recognize that the application can be practiced without the use of these specific details. In other instances, well-known structures and processes have not been described in detail in order to avoid obscuring the description of the application. Thus, the present application is not intended to be limited by the embodiments shown, but is to be accorded with the widest scope consistent with the principles and features disclosed.

[0029] As shown in Figures 1 to 5 , in one aspect, the embodiments of the present application provide an air outlet 11 structure which can guide the cold air upward when the air conditioner is in cooling operation, so as to avoid the cold air directly blowing on the user and improve the user's experience.

[0030] The air outlet 11 structure includes a shell 10, and the shell 10 is provided with an air outlet 11. The shell 10 can be, for example, a shell of an indoor unit of a split air conditioner such as a wall-mounted air conditioner or a cabinet air conditioner, or a shell of an integrated air conditioner such as a window air conditioner, and the embodiments of the present application do not limit this. The air outlet 11 has oppositely arranged upper and lower side walls 111 and 112, the upper side wall 111 extends obliquely upward and is provided with a flow guide groove 113. In this way, the surface of the upper side wall 111 is a surface with concave and convex fluctuations, which can form a Coanda effect on the airflow flowing through the surface of the upper side wall 111, so as to make the airflow flow along the surface of the upper side wall 111.

[0031] When the air conditioner is in cooling operation, the cold air output by the air conditioner passes through the air outlet 11, and the upper side wall 111 can produce a Coanda effect on the cold air, so as to make the cold air obliquely upwardly blow outward along the surface of the upper side wall 111, and then slowly descend based on the action of gravity after leaving the air outlet 11, forming a windless or less wind blowing effect, avoiding the cold air directly blowing on the user, and thus improving the user's experience.

[0032] The number and shape of the flow guide grooves 113 can be determined according to actual needs, and the embodiments of the present application do not limit this. As shown in Figure 2 and Figure 3 , in some embodiments, the upper side wall 111 can be provided with a plurality of flow guide grooves 113, and the plurality of flow guide grooves 113 are sequentially and spaced apart along the air outlet direction of the air outlet 11. In this way, the outlet airflow can tightly blow outward along the surface of the flow guide groove 113 in the extension direction of the flow guide groove 113, so that the upper side wall 111 can achieve a better wall-attached flow guiding effect.

[0033] In some examples, the width of the guide groove 113 can gradually increase along the air outlet direction of the air outlet 11; in other words, the width of the guide groove 113 at the air inlet side is smaller, and the width of the guide groove 113 at the air outlet side is larger. In this way, when the air outlet airflow is blown outward along the guide groove 113, the flow rate of the air outlet airflow decreases accordingly as the width of the guide groove 113 gradually increases, thereby increasing the wall-attached flow effect of the air outlet airflow and reducing the air outlet impact of the air outlet airflow, further reducing the air outlet feeling and improving the user experience.

[0034] As shown in FIGS. 1, 2 and 3, in some embodiments, the upper side wall 111 can be provided with a guide groove 113. The guide groove 113 is arranged in the width direction of the air outlet 11 and extends along the air outlet direction of the air outlet 11. In this way, the guide groove 113 can guide the air outlet airflow to flow along the surface of the upper side wall 111, thereby increasing the wall-attached flow effect of the air outlet airflow and reducing the air outlet impact of the air outlet airflow, further reducing the air outlet feeling and improving the user experience. Figure 4 and Figure 5 As shown in FIGS. 1, 2 and 3, in some embodiments, the upper side wall 111 can be provided with a guide groove 113. The guide groove 113 is arranged in the width direction of the air outlet 11 and extends along the air outlet direction of the air outlet 11. In this way, the guide groove 113 can guide the air outlet airflow to flow along the surface of the upper side wall 111, thereby increasing the wall-attached flow effect of the air outlet airflow and reducing the air outlet impact of the air outlet airflow, further reducing the air outlet feeling and improving the user experience.

[0035] The shape of the upper side wall 111 can be determined according to actual needs, which is not limited in the embodiments of the present application. In some embodiments, at least part of the area of the upper side wall 111 can be provided as an arc wall segment; the arc wall segment extends along the air outlet direction of the air outlet 11, and the center of the arc wall segment is located above the upper side wall 111. By providing the arc wall segment on the upper side wall 111, the upper side wall 111 can be smoothly inclined and extend upward, so that the air outlet airflow can be better blown upward along the surface of the upper side wall 111.

[0036] In some examples, the upper side wall 111 can have a planar wall segment and an arc wall segment. The planar wall segment and the arc wall segment are connected in sequence along the air outlet direction of the air outlet 11, and the guide groove 113 is arranged on the planar wall segment and the arc wall segment, respectively. The specific value of the radius of the arc wall segment can be determined according to actual needs, which is not limited in the embodiments of the present application. For example, the radius of the arc wall segment can be set to be not less than 80 mm. In this way, the arc wall segment can have a larger extension length, thereby ensuring the upward guiding effect of the arc wall segment on the air outlet airflow. In other examples, all areas of the upper side wall 111 can be provided as arc wall segments.

[0037] The specific value of the extension length of the upper side wall 111 can be determined according to actual needs, which is not limited in the embodiments of the present application. In some embodiments, the extension length of the upper side wall 111 can be set to be not less than 25 mm. In this way, the upper side wall 111 can have a larger extension length, thereby ensuring the upward guiding effect of the upper side wall 111 on the air outlet airflow.

[0038] As shown in FIGS. 1, 2 and 3, in some embodiments, the upper side wall 111 can be provided with a guide groove 113. The guide groove 113 is arranged in the width direction of the air outlet 11 and extends along the air outlet direction of the air outlet 11. In this way, the guide groove 113 can guide the air outlet airflow to flow along the surface of the upper side wall 111, thereby increasing the wall-attached flow effect of the air outlet airflow and reducing the air outlet impact of the air outlet airflow, further reducing the air outlet feeling and improving the user experience. Figures 1 to 6As shown, in another aspect, the embodiments of the present application provide an air conditioner, which comprises the air outlet 11 structure of any of the above embodiments. The type of air conditioner can be determined according to actual needs, and types such as wall-mounted air conditioners, cabinet air conditioners, window air conditioners, etc. can be used, and the embodiments of the present application do not limit this. The air conditioner provided by the embodiments of the present application has the air outlet 11 structure described above, which can guide the cold air to blow upward during cooling operation, avoid direct blowing of cold air to the user, and improve the user's experience.

[0039] In some embodiments, the air conditioner can comprise a deflector 20 movably arranged at the air outlet 11. The shell 10 can be provided with an inner air duct 12 communicating with the air outlet 11, the inner air duct 12 having a first side wall 121 and a second side wall 122 arranged opposite to each other; the first side wall 121 is connected with the upper side wall 111, and the second side wall 122 is connected with the lower side wall 112. When the air conditioner is in a heating mode, one end of the deflector 20 can abut against the first side wall 121, and the deflector 20 and the lower side wall 112 are spaced apart to form a hot air outlet channel, so that the hot air can be blown downward along the hot air outlet channel, quickly raising the indoor environment temperature, so that the indoor environment is relatively warm.

[0040] The air outlet structure and air conditioner provided by the embodiments of the present application are described in detail above, and specific examples are applied in this paper to explain the principles and implementation modes of the present application. The above embodiment description is only used to help understand the method and core idea of the present application; at the same time, for those skilled in the art, according to the idea of the present application, the specific implementation mode and application range will be changed, and the above description should not be understood as limiting the present application.
