[0027] The embodiments of the present application will be described in detail below with reference to the drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.

[0028] The embodiments of the present application will be described in detail below with reference to the drawings. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application. Figures 1 to 3 The housing assembly according to an embodiment of the present application and the air conditioner having the same will be described below.

[0029] As shown in Figures 1 to 3 , the housing assembly according to an embodiment of the present application includes a housing 1 and an air outlet duct 2. The bottom wall surface of the housing 1 is provided with an air inlet 11, the front wall surface of the housing 1 is provided with an air outlet 12, and the air outlet duct 2 is provided in the housing 1.

[0030] One end of the air outlet duct 2 is used to communicate with the impeller 3, and the other end of the air outlet duct 2 communicates with the air outlet 12. The air outlet duct 2 includes a first duct surface 21, which is provided on the top surface of the air outlet duct 2 and is connected to the upper edge of the air outlet 12. In the projection plane orthogonal to the left-right direction of the housing 1, a vertical downward extending perpendicular line L1 is drawn from the front end of the first duct surface 21 as a starting point. The angle between the vertical downward extending perpendicular line L1 and the first duct surface 21 is α, wherein 70°≤α≤110°.

[0031] As shown in Figure 2 , the direction of the perpendicular line L1 is the vertical downward direction. It can be understood that the angle α between the perpendicular line L1 and the first duct surface 21 is the angle between the vertical downward direction and the extension direction of the first duct surface 21 from front to back.

[0032] It should be noted that the up-down, front-back and left-right directions of the shell 1 are consistent with the up-down, front-back and left-right directions of the air conditioner after installation.

[0033] According to the shell assembly of the embodiment of the present application, the air outlet 12 is arranged on the front wall surface of the shell 1, so that the airflow after heat exchange is blown out towards the front side of the shell 1. Since the included angle between the first air duct surface 21 and the vertical line extending vertically downward is in the range of 70°-110°, the problem of rapid sinking of the blown-out airflow can be solved, which is conducive to the uniform flow of the airflow towards a large range of space in the room, thereby ensuring the consistency of the temperature in each area in the room and improving the use experience of the user.

[0034] In some examples, in the direction from back to front of the shell 1, the first air duct surface 21 can extend obliquely upward (i.e., the first air duct surface 21 gradually inclines upward), and the maximum angle of upward inclination is 20°.

[0035] In other examples, in the direction from back to front of the shell 1, the first air duct surface 21 can extend obliquely downward (i.e., the first air duct surface 21 gradually inclines downward), and the maximum angle of downward inclination is 20°.

[0036] For example, α can be 70°, 75°, 85°, 90°, 95°, 100°, 105°, 110°. The inventors of the present application have found through experiments that when the included angle α between the vertical line and the first air duct surface 21 is in the above range, the blowing distance of the air conditioner can be greatly improved, the blown-out airflow can be prevented from sinking rapidly, and the airflow can uniformly cover the entire room, thereby improving the uniformity of the temperature in the room.

[0037] Preferably, 90<α≤105°. When the air conditioner of the embodiment of the present application is installed on the ceiling, in order to prevent the airflow guided by the air outlet 12 from flowing upward, i.e., to prevent the air outlet 12 from blowing out on the ceiling, the first air duct surface 21 can gradually extend downward along the direction from back to front (i.e., α>90°), so as to guide the airflow downward, thereby improving the problem of airflow flowing on the ceiling. In order to prevent the blown-out airflow from sinking rapidly, α needs to be designed to be less than or equal to 105°, thereby further improving the blowing effect of the air conditioner.

[0038] It can be understood that when the air conditioner of the embodiment of the present application is working, in the cooling mode, the cold air can flow uniformly and slowly towards a large range, so as to achieve the purpose of rapid cooling and improve the comfort of the human body. In the heating mode, the hot air can fully fill each area of the room, the airflow uniformly covers the entire room, the uniformity of the temperature in the entire room area is ensured, and the overall comfort of the user is ensured.

[0039] In the examples of the present application, the air outlet 12 is arranged adjacent to the top of the shell 1 to increase the height of the air outlet 12 as much as possible, to avoid the problem of the blown air flow quickly sinking, and to reduce the discomfort caused by the straight blowing of the air flow to the user. In addition, the air conditioner of the embodiments of the present application can be installed on the top. It can be understood that, since the air in the environment does not need to enter the inside of the air conditioner indoor unit from directly above the shell 1, the distance between the air conditioner indoor unit and the top wall (ceiling) of the room can be greatly reduced or eliminated, thereby improving the space utilization of the room, especially for a room with a low height, the cramped feeling of the indoor space can be effectively reduced or eliminated.

[0040] Optionally, as shown in Figure 2 and Figure 3 , the air outlet air duct 2 includes a second air duct surface 22, which is arranged on the bottom surface of the air outlet air duct 2 and is connected to the lower edge of the air outlet 12, and the second air duct surface 22 extends downwardly in the rear-to-front direction. Since the second air duct surface 22 extends downwardly in the rear-to-front direction, a part of the blown air flow can flow downwardly, so that the temperature of the upper and lower regions in the room is more uniform. And the shell assembly of the embodiments of the present application can increase the blowing distance on the basis of large-angle blowing by arranging the first air duct surface 21 and the second air duct surface 22 as the above structure, to ensure that the air conditioner has a good air supply effect.

[0041] In an example, as shown in Figure 3 , the height difference between the first air duct surface 21 and the second air duct surface 22 is H, which gradually increases in the rear-to-front direction of the shell 1. It can be understood that the air outlet flow passage defined by the first air duct surface 21 and the second air duct surface 22 gradually widens in the rear-to-front direction of the shell 1, thereby increasing the blowing angle of the air outlet 12, which on the one hand can make the blown cold air or hot air more gentle, and on the other hand, the cold air and the hot air can quickly spread to each region in the room, which is beneficial to improve the comfort of the user.

[0042] Optionally, as shown in Figure 2 , the angle between the second air duct surface 22 and the up-down direction of the shell 1 is β1, wherein 15°≤β1≤75°. For example, β1 can be 15°, 25°, 35°, 45°, 55°, 65° or 75°. The inventors of the present application have found through experiments that when the angle β1 between the second air duct surface 22 and the up-down direction of the shell 1 is within the above range, the distance of the air supply of the air conditioner can be greatly increased, the blown air flow can be prevented from quickly sinking, and the air flow can uniformly cover the entire room, thereby improving the uniformity of the temperature in the room.

[0043] In some embodiments, as shown in Figure 2 and Figure 3As shown, the air outlet air duct 2 includes a third air duct surface 23 arranged at the bottom surface of the air outlet air duct 2, the front end of the third air duct surface 23 is connected with the rear end of the second air duct surface 22, the third air duct surface 23 extends downwardly along the rear-to-front direction, the angle between the second air duct surface 22 and the up-down direction of the shell 1 is β1, and the angle between the third air duct surface 23 and the up-down direction of the shell 1 is β2, wherein β2>β1.

[0044] It can be understood that the third air duct surface 23 is arranged at the lower side of the inner wall of the air outlet air duct 2, and the third air duct surface 23 is located at the rear side of the second air duct surface 22, that is, the airflow in the air outlet air duct 2 first passes through the third air duct surface 23, then passes through the second air duct surface 22, and finally is discharged through the air outlet 12.

[0045] The shell assembly of the embodiment of the utility model satisfies β2>β1, so that the second air duct surface 22 is inclined downwardly to a greater extent than the third air duct surface 23, thereby reducing the resistance of the airflow when being discharged from the air outlet air duct 2 and reducing the energy consumption of the air conditioner.

[0046] Optionally, the angle between the second air duct surface 22 and the third air duct surface 23 is θ, wherein 110°≤θ≤170°. For example, θ can be 110°, 130°, 140°, 160° or 170°. The inventors of the present application have found through experiments that when the angle θ between the second air duct surface 22 and the third air duct surface 23 is within the above range, the air supply distance of the air conditioner can be extended, the air supply angle of the air conditioner is increased, the airflow blown out is affected by the wall effect and flows close to the lower edge of the air outlet 12, the resistance of the airflow is reduced, the energy consumption is reduced, the airflow is blown into the room normally, and the comfort of the user when blowing air is ensured.

[0047] In an example, as shown in Figure 3 The connecting position of the first air duct surface 21 and the second air duct surface 22 has a transition curved surface 25. For example, the first air duct surface 21 and the second air duct surface 22 have a transition round corner, so that the airflow is blown out more smoothly, the resistance of the airflow is reduced, the energy consumption is reduced, the noise when the airflow is blown out is reduced, and the user experience is improved.

[0048] Optionally, the front end of the first air duct surface 21 is closer to the front side of the shell 1 than the front end of the second air duct surface 22. In other words, the front end of the first air duct surface 21 is located at the front side of the front end of the second air duct surface 22, so that the air guide path of the first air duct surface 21 is extended, the air blowing distance of the air conditioner is longer, the blown cold air or hot air flows uniformly and slowly towards a larger range, and the purpose of rapid cooling (heating) is achieved.

[0049] In the example of the present application, in order to adapt to the structure of the air outlet end of the air outlet air duct 2, the upper edge of the air outlet 12 is located in front of the lower edge of the air outlet 12. Thus, when the air conditioner is working, the airflow after heat exchange flows along the air outlet air duct 2 and is discharged through the air outlet 12, which can reduce the resistance of the airflow flow and has a better air supply effect.

[0050] Specifically, as shown in Figure 2 and Figure 3 , the shell 1 has a front panel 13, the air outlet 12 is arranged on the front panel 13, and the front panel 13 is gradually inclined backward along the upward direction, so that the upper edge of the air outlet 12 is located in front of the lower edge of the air outlet 12, thereby improving the air supply effect of the air conditioner.

[0051] Wherein, the included angle between the second air duct surface 22 and the front panel 13 is γ, wherein 110°≤γ≤160°. For example, γ can be 110°, 120°, 140°, 160°. The inventors of the present application have found through experiments that when the included angle γ between the second air duct surface 22 and the front panel 13 is within the above range, the airflow can be affected by the wall effect and flow closely along the lower edge of the air outlet 12 and the front panel 13, thereby reducing the resistance of the airflow flow and making the temperature in the entire room more balanced and improving the temperature consistency in each area of the room.

[0052] Optionally, as shown in Figure 2 and Figure 3 , the air outlet air duct 2 comprises a volute tongue 24, the volute tongue 24 comprises a windward surface 241 adjacent to one side of the fan wheel 3, the upper end of the windward surface 241 is connected with the bottom surface (the third air duct surface 23) of the air outlet air duct 2, and the lower end of the windward surface 241 extends along the circumferential direction of the fan wheel 3. Thus, the stability of the airflow flow when the air outlet air duct 2 is blowing can be improved, and the noise generated by the airflow impacting the air outlet air duct 2 can be reduced, thereby improving the user's use comfort.

[0053] As shown in Figure 2 Figure 3 Figure 2 , another embodiment of the air conditioner of the present application comprises: a heat exchanger 4, a fan wheel 3 and a shell assembly, the shell assembly is the shell assembly of the present application, and the heat exchanger 4 and the fan wheel 3 are arranged in the shell 1. Specifically, the heat exchanger 4 is generally in a V-shaped structure, the fan wheel 3 is arranged on the upper side of the heat exchanger 4, and the air inlet 11 is arranged opposite to the lower wall surface of the heat exchanger 4 to heat the airflow entering the shell 1.

[0054] According to the air conditioner of the embodiment of the utility model, the air outlet 12 is arranged on the front wall surface of the shell 1, so that the airflow after heat exchange is blown towards the front side of the shell 1, the included angle between the first air duct surface 21 and the vertical line extending vertically downwards is within the above range, the problem of the blown airflow sinking quickly can be solved, the airflow is beneficial to flow uniformly towards the space of a larger range in the room, so that the consistency of the temperature of each area in the room can be ensured, and the use experience of the user is improved.
