[0002] At present, air-conditioning products with the function of introducing fresh air from the outside have air outlets in the front, rear, and side modes. The same model can only realize a certain air outlet mode, and the position of the air outlet cannot be switched. Although the effective air supply area of ​​the air outlet can be adjusted or the air sweeping can be realized at the same time, the air supply form is relatively simple. For air-conditioning products with multiple air outlets, if some air outlets are closed by using swing blades or door panels without turning off the fan, the internal channels corresponding to the air outlets cannot be effectively cut off. The matching gaps near the closed air outlets and in the air duct will cause air leakage, and may also produce abnormal noises, affecting the user experience. The air supply effect of the remaining normally opened air outlets will also be affected by the air outlets that are not completely cut off, thereby reducing the use effect. Summary of the invention

DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown, the first subject of the present invention, the air outlet structure of the air conditioner, is used for switching the air supply channel of the air conditioner, and includes a centrifugal air supply component 1 and an air duct structure 2. The centrifugal air supply component 1 supplies air to the air duct structure 2. The centrifugal air supply component 1 is provided with an air inlet and an air outlet 11. Figure 3 The duct structure 2 forms an air duct, and the side wall of the duct structure 2 is provided with an air duct inlet 21, which is connected to the air outlet 11 of the centrifugal air supply component 1. The airflow from the centrifugal air supply component 1 enters the air duct through the air duct inlet 21. The duct structure 2 is provided with a switching member 3 at the air duct inlet 21, and the switching member 3 can swing back and forth relative to the duct structure 2. Figure 6 , a rotating shaft 31 is respectively arranged on both sides of the switching member 3, and a group of shaft holes 22 are arranged on the air duct structure 2, and the rotating shaft 31 is installed in the shaft holes 22. The rotating shaft 31 of the switching member 3 is also equipped with a motor 4 for controlling the swing position of the switching member 3. The motor 4 is a stepping motor, which controls the switching member 3 to swing to the extreme position and relatively fix it. The switching member 3 divides the air duct formed by the air duct structure 2 into a first air outlet channel 23 and a second air outlet channel 24, see Figure 7 to Figure 9 When the switching member 3 swings around the rotating shaft 31 to the extreme position, the air duct inlet 21 is connected to the first air outlet channel 23 or the second air outlet channel 24. The switching member 3 swings to two extreme positions, corresponding to the first air outlet channel 23 and the second air outlet channel 24 respectively.

[0032] The air duct structure 2 can be a single part or assembled from multiple parts. Figure 1 , Figure 2 , Figure 4 and Figure 5 The air duct structure 2 includes an air duct lower structure 25 and an air duct upper structure 26, which are combined to form an air duct. The air duct air inlet 21 is provided on the air duct lower structure 25, and the shaft hole 22 is provided on the air duct upper structure 26. The shapes of the air duct upper structure 26 and the air duct lower structure 25 are flexibly set according to factors such as the arrangement of the air duct and the allowable space inside the product.

[0033] In order to avoid air leakage in the gap between the switching member 3 and the duct structure 2, the duct air inlet 21 is rectangular, and the duct is rectangular in the cross section perpendicular to the center line of the duct. The duct air inlet 21 is preferably set at the bottom of the duct structure 2, so that the airflow direction of the duct air inlet 21 is vertically upward, and then enters the first air outlet channel 23 or the second air outlet channel 24 after a 90° turn. The switching member 3 includes two side surfaces, which correspond to the first air outlet channel 23 and the second air outlet channel 24 respectively. When the switching member 3 swings to the extreme position, the lower edge of the switching member 3 cooperates with the edge of the duct air inlet 21, see Figure 8 , Fig. 9 , Fig.10 and Fig.11 A web is provided between the two sides of the switching member 3 to separate them and form a cavity structure. Figure 6 , Figure 8 and Fig. 9 Or, the upper and lower ends of the two sides of the switching member 3 are closed, see Figures 10-12 . When there is a temperature difference between the introduced air and the indoor air, there will also be a temperature difference on the two sides of the switching member 3. The two sides of the switching member 3 are a cavity structure, which can significantly reduce the risk of condensation on the two side surfaces. The two sides of the switching member 3 are preferably curved structures. When the angle between the two switching channels is large, that is, when the angle between the airflow direction of the air duct inlet 21 and the airflow direction of the first air outlet channel 23 is large, when the angle between the airflow direction of the air duct inlet 21 and the airflow direction of the second air outlet channel 24 is large, the airflow can pass more smoothly. Both sides of the switching member 3 are curved structures, the strength of the switching member 3 is better, and the risk of deformation of the switching member 3 under long-term stress can be reduced, thereby improving reliability.

[0034] In order to facilitate the installation of the switching member 3, the air duct inlet 21 is preferably arranged at the bottom of the air duct structure 2, and a mounting hole 28 penetrating the top of the air duct structure 2 is arranged just above the air duct inlet 21, and the mounting hole 28 is used to install the switching member 3. Shaft holes 22 are respectively arranged on opposite sides of the mounting hole 28, and the upper part of the switching member 3 is located outside the mounting hole 28, and the lower part of the switching member 3 cooperates with the edge of the air duct inlet 21, see Figure 7 to Figure 11 In order to limit the swing amplitude of the switching member 3, a swing limiting structure is provided between the upper sides of the switching member 3 and the two side edges of the assembly hole 28. For example, see Figure 6 to Figure 12 The swing limit structure is as follows: a step 32 is provided on the upper part of the switching member 3, and a hanging platform 27 adapted to the step 32 of the switching member 3 is provided on the edge of the assembly hole 28 of the air duct structure member 2. An adapted magnet can also be provided between the step 32 and the hanging platform 27.

[0035] like Figure 8 and Fig.10As shown, when the motor 4 drives the lower part of the switching member 3 to swing to the left to the extreme position, the lower edge of the right side of the switching member 3 cooperates with the left edge of the air duct inlet 21, and the upper edge of the right side of the switching member 3 cooperates with the right edge of the assembly hole 28 to form a complete air duct to the right, the first air outlet channel 23 is closed, and the second air outlet channel 24 is opened. Fig. 9 and Fig.11 As shown, when the motor 4 drives the lower part of the switching member 3 to swing to the right to the extreme position, the lower edge of the left side of the switching member 3 cooperates with the right edge of the air duct inlet 21, and the upper edge of the left side of the switching member 3 cooperates with the left edge of the assembly hole 28 to form a complete air duct to the left, the first air outlet channel 23 is opened, and the second air outlet channel 24 is closed.

[0036] The second subject of the present invention is an indoor unit of an air conditioner, which aims to enable the air conditioner to switch the air supply channel and avoid abnormal problems caused by airflow running around inside the air conditioner. Figure 13 to Figure 16 The air-conditioning indoor unit includes a shell 5 and any of the above-mentioned air-conditioning outlet structures installed inside the shell 5. The shell 5 includes a front panel and a back panel. A front air outlet 51 is arranged on the front of the shell 5, and the front air outlet 51 is connected to the first air outlet channel 23. A back air outlet 52 is arranged on the back of the shell 5, and the back air outlet 52 is connected to the second air outlet channel 24.

[0037] The air-conditioning outlet structure can switch the air duct of fresh air or circulating air. For example, a fresh air inlet 53 is provided on the back of the housing 5, and the air inlet of the centrifugal air supply assembly 1 is connected to the fresh air inlet 53. The air-conditioning outlet structure switches the air duct of fresh air to achieve completely different air supply effects before and after. An air-conditioning outlet 54 is also provided on the front of the housing 5, and an air-conditioning inlet 55 is also provided on the back of the housing 5. The air-conditioning outlet 54 and the air-conditioning inlet 55 are the inlets and outlets of circulating air.
