DETAILED DESCRIPTION

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] First embodiment

[0026] Please refer to Figure 1 and Figure 2 The embodiment of the present invention provides an air duct housing 100 for assembling to form an air conditioner. It can make the airflow blown out of the air duct 121 blow to the extension wall 110 to prevent the extension wall 110 from generating condensation, thereby improving the user experience. In this embodiment, the air duct housing 100 is applied to an air conditioner cabinet, and the air conditioner cabinet can blow hot air or cold air into the room through the air duct 121 of the air duct housing 100 to adjust the indoor temperature.

[0027] The air duct housing 100 includes an extension wall 110, a shell body 120, an air guide bracket 130, a blade mounting frame 140, a protective net 150 and a vertical air sweeping blade 160. The extension wall 110 and the blade mounting frame 140 are fixedly connected to the shell body 120, the air guide bracket 130 and the protective net 150 are detachably mounted on the shell body 120, the vertical air sweeping blade 160 is mounted on the blade mounting frame 140, the air guide bracket 130 is used to guide the airflow, the protective net 150 is used to prevent foreign objects from extending into the air duct 121 to cause safety accidents, and the vertical air sweeping blade 160 is used to adjust the blowing direction of the airflow. The blade mounting frame 140 is fixedly connected to the inner side of the extension wall 110, that is, the vertical air sweeping blade 160 is arranged on the inner side of the extension wall 110, and the extension wall 110 can protect and shield the vertical air sweeping blade 160 installed on the blade mounting frame 140.

[0028] It is worth noting that the shell body 120 has an air duct 121, and the air conditioner cabinet can blow out hot air or cold air through the air duct 121. The air duct 121 is relatively provided with a first side wall 122 and a second side wall 123, and the first side wall 122 and the second side wall 123 are both provided on the shell body 120, and the air flow can be blown out to the room through the first side wall 122 and the second side wall 123. In this embodiment, the extension wall 110 is integrally formed with the first side wall 122 to improve the connection strength, but it is not limited to this. In other embodiments, the extension wall 110 can also be separated from the first side wall 122 and can be detachably connected. The extension wall 110 is provided at the end of the first side wall 122, and the extension wall 110 is inclined to the first side wall 122 and extends in a direction away from the second side wall 123, that is, the extension direction of the extension wall 110 is inclined to the air outlet direction of the air duct 121. A through groove 124 is formed at one end of the first side wall 122 close to the extension wall 110, and the through groove 124 is connected to the air duct 121. The through groove 124 enables the airflow blown out from the air duct 121 to blow to the extension wall 110 to prevent condensation on the extension wall 110, and the airflow can be blown into the room along the extension wall 110, thereby increasing the air outlet range and improving the temperature control efficiency.

[0029] It should be noted that the second side wall 123 is spaced apart from the first side wall 122, and the air duct 121 is disposed between the first side wall 122 and the second side wall 123. The air guide bracket 130 is fixedly connected to the second side wall 123, and the air guide bracket 130 is spaced apart from the extension wall 110. An air outlet cavity 170 is formed between the air guide bracket 130 and the extension wall 110, and the air outlet cavity 170 is connected to the air duct 121, and the air flow blown out from the air duct 121 is blown out into the room through the air outlet cavity 170. In this embodiment, the side of the air guide bracket 130 close to the air outlet cavity 170 is on the same plane as the second side wall 123, that is, the side of the air guide bracket 130 close to the air outlet cavity 170 is an extension surface of the second side wall 123. Since the extension wall 110 is inclined to the first side wall 122 and extends in a direction away from the air duct 121, the air outlet area of ​​the air outlet cavity 170 is larger than the air outlet area of ​​the air duct 121. The airflow is blown into the room through the air outlet cavity 170, thereby increasing the air outlet range.

[0030] It is worth noting that one end of the blade mounting frame 140 is fixedly connected to the extension wall 110, and the other end is fixedly connected to the second side wall 123. In this embodiment, the extension wall 110 is integrally formed with the second side wall 123 through the blade mounting frame 140 to improve the connection strength. The blade mounting frame 140 is arranged between the extension wall 110 and the air guide bracket 130, that is, the blade mounting frame 140 is arranged in the air outlet cavity 170 between the extension wall 110 and the air guide bracket 130. The vertical air sweeping blade 160 installed on the blade mounting frame 140 can sweep air in the air outlet cavity 170 to adjust the air outlet direction.

[0031] In this embodiment, one end of the protective net 150 is fixedly connected to the first side wall 122 and is disposed at one end of the first side wall 122 close to the extension wall 110. The protective net 150 is disposed at the end of the first side wall 122, and the position of the connection between the protective net 150 and the first side wall 122 corresponds to the position of the through slot 124. The other end of the protective net 150 is fixedly connected to the air guide bracket 130. The protective net 150 is disposed between the air outlet cavity 170 and the air duct 121. The airflow blown out from the air duct 121 enters the air outlet cavity 170 through the protective net 150 and is then blown out into the room. The protective net 150 can prevent foreign objects from extending into the air duct 121, thereby preventing the occurrence of safety accidents.

[0032] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6It should be noted that the through slot 124 has a bottom wall 125, and the bottom wall 125 is arranged at a preset angle with the extension direction of the first side wall 122. The extension direction of the first side wall 122 is the air outlet direction of the air duct 121, and the airflow can be blown outward along the first side wall 122 and blown to the extension wall 110 through the through slot 124. Specifically, the through slot 124 is an oblique slot, and the extension direction of the through slot 124 is inclined to the first side wall 122, that is, the bottom wall 125 is inclined to the first side wall 122, and the preset angle ranges from 45 degrees to 75 degrees. In this embodiment, the preset angle is 60 degrees, but it is not limited to this. In other embodiments, the preset angle can be 45 degrees or 75 degrees. The size of the preset angle is not specifically limited and needs to be determined according to the specific product structure. For ease of understanding, the preset angle is represented as a.

[0033] Furthermore, the through slot 124 is further provided with a first end wall 126 and a second end wall 127, the first end wall 126 is provided above the bottom wall 125, the second end wall 127 is provided below the bottom wall 125, the bottom wall 125 is provided between the first end wall 126 and the second end wall 127, and the first end wall 126, the bottom wall 125 and the second end wall 127 together enclose the through slot 124. In this embodiment, the first end wall 126 and the second end wall 127 are both triangular, that is, the through slot 124 is obliquely penetrated on two adjacent surfaces of the first side wall 122, so as to guide the airflow in the air duct 121 into the through slot 124, so that the airflow is blown to the extension wall 110.

[0034] In this embodiment, the cross section of the extension wall 110 is arc-shaped, and the vertical wind sweeping blade 160 installed on the blade mounting frame 140 is arranged on the concave side of the extension wall 110. The extension wall 110 can give way to the vertical wind sweeping blade 160 to avoid interference with the rotation of the vertical wind sweeping blade 160. However, it is not limited to this. In other embodiments, the cross section of the extension wall 110 can also be in a broken line shape or a straight line shape, and the shape of the extension wall 110 is not specifically limited.

[0035] Specifically, the extension wall 110 is relatively provided with a first end 111 and a second end 112, and the first end 111 is fixedly connected to the shell body 120. The airflow blown out from the air duct 121 is blown to the first end 111 through the through groove 124, and then flows along the extension wall 110 to the second end 112, and finally leaves the second end 112 and blows into the room. In this process, the airflow takes away and eliminates the ambient air in the recessed side of the extension wall 110 to avoid condensation on the extension wall 110.

[0036] In this embodiment, the extension direction of the through groove 124 is the same as the direction of the line connecting the first end 111 and the second end 112. The line connecting the first end 111 and the second end 112 is the chord between the two ends of the arc of the extension wall 110. The airflow is blown to the extension wall 110 through the through groove 124, that is, it is blown to the extension wall 110 from the chord length direction of the extension wall 110, which can make the airflow flow outward along the extension wall 110, enhance the guide effect, and prevent condensation from forming on the extension wall 110.

[0037] It should be noted that a diffusion groove 113 is provided on the extension wall 110, and one end of the through groove 124 away from the air duct 121 is connected to the diffusion groove 113. The diffusion groove 113 is used to diffuse and guide the airflow passing through the through groove 124, so that this part of the airflow can be evenly blown to various positions on the extension wall 110. The airflow is evenly diffused and the guiding effect is good, thereby preventing condensation from occurring at local positions of the extension wall 110.

[0038] In this embodiment, the diffusion slot 113 is trumpet-shaped, and the diffusion slot 113 is relatively provided with a large end 114 and a small end 115, the large end 114 is connected with the small end 115, the small end 115 is connected with the through slot 124, and the large end 114 extends to the end of the extension wall 110 away from the first side wall 122. The airflow blown out from the air duct 121 enters the small end 115 through the through slot 124, and then diffuses outward uniformly under the action of the diffusion slot 113, wherein a part of the airflow leaves the extension wall 110 through the large end 114 and blows into the room, and another part of the airflow leaves the diffusion slot 113 and blows to various positions on the extension wall 110, so as to prevent condensation from forming on the extension wall 110.

[0039] In the air duct housing 100 described in the embodiment of the present invention, the air duct 121 is relatively provided with a first side wall 122 and a second side wall 123, the extension wall 110 is arranged obliquely to the first side wall 122 and extends in a direction away from the second side wall 123, and a through slot 124 is provided at one end of the first side wall 122 close to the extension wall 110, and the through slot 124 is connected to the air duct 121, and the through slot 124 can make the airflow blown out of the air duct 121 blow to the extension wall 110 to prevent the extension wall 110 from generating condensation. Compared with the prior art, the air duct housing 100 provided by the present invention adopts the extension wall 110 arranged obliquely to the first side wall 122 and the through slot 124 opened on the first side wall 122, so that the airflow blown out of the air duct 121 can blow to the extension wall 110 to prevent the extension wall 110 from generating condensation, thereby improving the user experience.
