[0034] (2) When the inclination angles of the plurality of air guide plates are within a first preset range, the air guide plates are in a first working state; when the inclination angles of the plurality of air guide plates are within a second preset range, the air guide plates are in a second working state; the air outlet resistance is reduced, the air outlet is smooth, and vortexes are avoided at the air outlet, thereby improving the air outlet effect; and the problems of large air outlet resistance, unsmooth air outlet, and high noise are solved;

[0052] In existing cabinet-type air conditioner indoor units, an air duct is formed inside the housing, and an air outlet connected to the air duct is formed on the upper side of the housing side wall, which can realize upward air discharge. However, due to the position of the air outlet, the air outlet can only realize oblique upward air discharge, and cannot realize horizontal air discharge or oblique downward air discharge. As a result, the air outlet direction adjustment range is narrow, the temperature adjustment in the vicinity is not timely, and the adjustment accuracy is low.

[0053] The present invention creatively provides a cabinet-type air-conditioning indoor unit, comprising a shell and an air outlet mechanism, wherein a main air duct is formed inside the shell, an air outlet is formed on the side wall of the shell, and the air outlet is located at the top of the main air duct; the air outlet mechanism is arranged in the main air duct and close to the air outlet, and the air outlet mechanism comprises a first air outlet shell, a second air outlet shell, an air guide plate and a first wind shield plate: the first air outlet shell is arranged to form a first air outlet duct, the second air outlet shell is arranged on the top of the first air outlet shell and the second air outlet shell is arranged to form a second air outlet duct, the main air duct, the first air outlet shell and the second air outlet shell are arranged to form a second air outlet duct, The air outlet duct and the second air outlet duct are connected in sequence; the air guide plate is rotatably arranged in the first air outlet duct, and the first air shield plate is arranged in the second air outlet duct and away from the air outlet; when the air guide plate is in a first working state, the air in the first air outlet duct enters the second air outlet duct through the air guide plate, flows toward the air outlet, and is then discharged obliquely upward through the air outlet; when the air guide plate is in a second working state, the air in the first air outlet duct enters the second air outlet duct through the air guide plate, flows toward the first air shield plate, and is then discharged obliquely downward through the second air outlet duct and the air outlet;

[0054] The adjustment range of the air outlet direction has been expanded, so that the air outlet can discharge air obliquely upward to achieve long-distance air supply, or obliquely downward to achieve close-range and soft air supply, so that users can feel the breeze and can adjust the temperature nearby in time with high adjustment accuracy; it prevents the problem of strong cold air blowing directly on users, which may make users feel uncomfortable.

[0055] Example 1

[0056] like Figure 1 As shown, this embodiment provides a cabinet-type air-conditioning indoor unit, including a housing and an air outlet mechanism. A main air duct is formed inside the housing, and an air outlet 23 is formed on the side wall of the housing. The air outlet 23 is located at the top of the main air duct, which improves the appearance. The housing includes a front housing 21 and a rear housing 22. The front housing 21 and the rear housing 22 are buckled together to form the main air duct. The front housing 21 forms the air outlet 23, and the rear housing 22 forms a through hole.

[0057] The air outlet mechanism is arranged in the main air duct and close to the air outlet 23. The air outlet mechanism includes:

[0058] A first air outlet housing 11 is provided, which encloses a first air outlet duct 111. The first air outlet duct 111 extends in a vertical direction, and an air inlet end of the first air outlet duct 111 is connected to the main air duct;

[0059] The second air outlet housing 12 is disposed on top of the first air outlet housing 11 and is configured to form a second air outlet duct 121. The second air outlet duct 121 extends horizontally, with an air inlet end of the second air outlet duct 121 communicating with the air outlet end of the first air outlet duct 111, and an air outlet end of the second air outlet duct 121 communicating with the air outlet 23. Specifically, the second air outlet housing 12 has an air inlet end formed on a side wall thereof adjacent to the first air outlet housing 11, and an air outlet end of the second air outlet duct 121 formed at one end thereof. The top of the side wall of the second air outlet duct 121 is tilted downward, and an angle θ is formed between the top of the side wall of the second air outlet duct 121 and the horizontal direction.

[0060] The wind deflector 13 is rotatably disposed in the first air outlet 111, so that the wind deflector 13 can be rotated to different angles to achieve air outlet in different directions; the wind deflector 13 has a first working state and a second working state; specifically, Figure 3a and Figure 3b As shown, the air guide plate 13 is arranged at the air outlet end of the first air outlet 111, and the air guide plate 13 can open or close the first air outlet 111; the air guide plate 13 includes a plurality of air guide plates 13, and the plurality of air guide plates 13 are sequentially spaced apart along the width direction of the first air outlet 111; the plurality of air guide plates 13 can be controlled to rotate independently or synchronously; specifically, when the housing is a rectangular parallelepiped structure, the plurality of air guide plates 13 are sequentially spaced apart along the thickness direction of the housing;

[0061] The first wind shield 14 is disposed within the second air outlet 121 and away from the air outlet 23. On the one hand, the first wind shield 14 can block the end of the second air outlet 121 away from the air outlet 23. On the other hand, the first wind shield 14 can serve as a wind guide. Specifically, the end of the second air outlet 121 away from the air outlet 23 is disposed at the through hole. The first wind shield 14 can block the end of the second air outlet 121 away from the air outlet 23 and the through hole.

[0062] like Figure 2a As shown, when the air guide plate 13 is in the first working state, the air in the first air outlet 111 enters the second air outlet 121 through the air guide plate 13 and flows directly to the air outlet 23, and is then discharged obliquely upward through the air outlet 23, thereby achieving long-distance air supply. When the cabinet air conditioner is operating in the cooling mode, the air guide plate 13 can be placed in the first working state;

[0063] like Figure 2b As shown, when the air guide plate 13 is in the second working state, the air in the first air outlet 111 enters the second air outlet 121 through the air guide plate 13, and flows directly to the first wind shield 14, and then is discharged obliquely downward through the second air outlet 121 and the air outlet 23, realizing close-range and soft air supply, so that the user can feel the breeze, and can adjust the nearby temperature in time with high adjustment accuracy; the adjustment range of the air outlet direction is expanded to meet different air supply needs.

[0064] Further, if Figure 2a As shown, when the air guide plate 13 is in the first working state, the air guide plate 13 directs the air outflow of the first air outlet 111 toward the air outlet 23, and then the air in the first air outlet 111 is discharged obliquely upward through the second air outlet 121 and the air outlet 23;

[0065] like Figure 2b As shown, when the wind guide plate 13 is in the second working state, the wind guide plate 13 makes the air outlet direction of the first air outlet 111 toward the first wind shield 14, and then the air in the second air outlet 121 is discharged obliquely downward through the first wind shield 14, the second air outlet 121 and the air outlet 23.

[0066] To address the problem of low air flow direction adjustment accuracy caused by an inappropriate inclination angle of the air guide plates 13, this embodiment proposes that when the inclination angles of the multiple air guide plates 13 are within a first preset range, the air guide plates 13 are in a first working state; when the inclination angles of the multiple air guide plates 13 are within a second preset range, the air guide plates 13 are in a second working state; thereby reducing air flow resistance, ensuring smooth air flow, avoiding the formation of vortices at the air outlet 23, and improving the air flow effect; and solving the problems of large air flow resistance, uneven air flow, and high noise.

[0067] The first preset interval is [α1, α2], where α1 is the angle between the line connecting the rotation center of the first preset air guide plate and the lowest point of the lower edge of the air outlet 23 and the horizontal plane, and α2 is the angle between the line connecting the rotation center of the second preset air guide plate and the highest point of the upper edge of the air outlet 23 and the horizontal plane; the second preset interval is [β1, β2], where β1 is the angle between the line connecting the rotation center of the first preset air guide plate and the highest point of the upper edge of the first wind shield and the horizontal plane, and β2 is the angle between the line connecting the rotation center of the second preset air guide plate and the lowest point of the lower edge of the first wind shield and the horizontal plane;

[0068] The first preset wind guide plate is close to the air outlet 23 , and the second preset wind guide plate is close to the first wind shield 14 .

[0069] Specifically, when it is necessary to discharge air obliquely upward, the air guide plate 13 is rotated from the closed state to one side of the rear housing 22 toward the air outlet 23, and the air guide plate 13 is rotated within a first preset range to achieve air discharge within the oblique upward range; the air flows directly to the air outlet 23 through the air guide plate 13;

[0070] When it is necessary to discharge air obliquely downward, the air guide plate 13 is rotated toward one side of the front shell 21 toward the first wind shield 14, and the air guide plate 13 is rotated within the second preset range to achieve air discharge within the oblique downward range; the air flows directly to the first wind shield 14 through the air guide plate 13, and flows to the top of the side wall of the second air outlet shell 12 through the action of the first wind shield 14, and flows to the air outlet 23 through the top of the side wall of the second air outlet shell 12 and is discharged obliquely downward.

[0071] Furthermore, the rotation centers of the plurality of air guide plates 13 are on the same reference line, the reference line is tilted, and an end of the reference line close to the first air shield 14 is higher than an end of the reference line close to the air outlet 23 .

[0072] To address the problem of a narrow air guide range of the first air shield 14, this embodiment proposes that the first air shield 14 is rotatably disposed within the second air outlet duct 121 and extends from the bottom of the side wall of the second air outlet housing 12 toward the top of the side wall of the second air outlet housing 12; the first air shield 14 is sealed to the side wall of the second air outlet housing 12;

[0073] When the wind guide plate 13 is in the second working state, the inclination angle of the first wind shield plate 14 is adjusted to adjust the air outlet direction of the air outlet 23;

[0074] Specifically, the bottom of the first wind shield 14 is rotatably arranged on the bottom of the side wall of the second air outlet shell 12 through a rotating shaft, and the side of the first wind shield 14 and the top of the first wind shield 14 are sealed with the side wall of the second air outlet shell 12 through a bellows to prevent the wind from flowing out through the gap between the first wind shield 14 and the side wall of the second air outlet shell 12 when the first wind shield 14 rotates, resulting in a reduction in air output.

[0075] Example 2

[0076] like Figure 4 As shown, based on Example 1, to address the problem that the outgoing air easily forms vortices in the second air outlet duct 121, resulting in a loss of air volume, this embodiment proposes that the air outlet mechanism further includes a second air shield 15, which is rotatably disposed in the second air outlet duct 121 and extends from the first air shield 14 toward the air outlet 23; the second air shield 15 is sealed to the side wall of the second air outlet housing 12;

[0077] When the wind guide plate 13 is in the second working state, the inclination angle of the second wind shield plate 15 can be adjusted to adjust the air outlet direction of the air outlet 23;

[0078] Specifically, one end of the second wind shield 15 is rotatably arranged on the top of the side wall of the second air outlet shell 12 through a rotating shaft, and the other end of the second wind shield 15 and the side of the second wind shield 15 are sealed with the side wall of the second air outlet shell 12 through a bellows to prevent the wind from flowing out through the gap between the second wind shield 15 and the side wall of the second air outlet shell 12 when the second wind shield 15 rotates, resulting in a reduction in the air output.

[0079] At the same time, the inclination angles of the first wind shield 14 and the second wind shield 15 can be flexibly adjusted to adjust the air outlet direction of the air outlet 23 to achieve large-scale and multi-directional air supply to meet the different needs of users and avoid the formation of vortex wind in the second air outlet duct 121, which leads to a reduction in air output.

[0080] Example 3

[0081] Based on Example 1, to address the problem that a portion of the air is discharged upward through the air outlet 23 when the air guide plate 13 is in the second working state, this embodiment proposes that the air outlet mechanism further includes a third air shield plate, which is telescopically or slidably disposed on the top of the second air outlet housing 12 and extends from the first air shield plate 14 toward the air outlet 23.

[0082] The third wind shield is extended. Since a part of the third wind shield exceeds the air outlet 23, the air discharged from the fan through the air outlet 23 can flow downward or horizontally under the action of the third wind shield, thereby achieving the purpose of adjusting the air outlet direction of the air outlet 23.

[0083] To address the problem that part of the wind flowing through the third wind shield will flow to the left and right sides of the housing, resulting in a loss of air flow, this embodiment proposes that the air outlet mechanism further includes a fourth wind shield and a fifth wind shield. The fourth wind shield is telescopically or slidably disposed on an outer side of the second air outlet housing 12; the fifth wind shield is telescopically or slidably disposed on the other outer side of the second air outlet housing 12.

[0084] The third wind shield, the fourth wind shield and the fifth wind shield are extended, and the third wind shield, the fourth wind shield and the fifth wind shield can be surrounded to form an air guide cavity, which is connected to the second air outlet duct 121, and the wind in the second air outlet duct 121 can be discharged through the air guide cavity.

[0085] Furthermore, the third windshield is made of a flexible material; a first sliding groove is formed on a side of the fourth windshield close to the fifth windshield, and a second sliding groove is formed on a side of the fifth windshield close to the fourth windshield;

[0086] When the third wind shield, the fourth wind shield, and the fifth wind shield are extended, the two sides of the third wind shield are respectively embedded in the first chute and the second chute, and the first chute and the second chute meet the requirements of the wind in the second air outlet duct 121 being discharged obliquely downward through the air guide cavity;

[0087] In this way, the wind guide plate 13, the first wind shield plate 14 and the wind guide cavity guide the air flow throughout the entire process, so that more wind is discharged horizontally or obliquely downward, thereby increasing the air output.

[0088] Example 4

[0089] Based on Example 1, to address the problem that a portion of the air is discharged upward through the air outlet 23 when the air guide plate 13 is in the second working state, this embodiment proposes that the air outlet mechanism further includes an air guide housing, which is telescopically or slidably mounted on the outer side of the second air outlet housing 12 and extends in the same direction as the second air outlet housing 12.

[0090] The air guide shell has a third working state and a fourth working state. When the air guide shell is in the third working state, the air guide shell is located between the air outlet 23 and the first wind shield 14, and the air guide shell is hidden, which does not affect the oblique upward air outlet of the air outlet 23; when the air guide shell is in the fourth working state, the air guide shell is formed with an air guide duct, which is located at the air outlet end of the second air outlet duct 121 and is connected to the second air outlet duct 121. The wind of the second air outlet duct 121 can be discharged through the air guide duct, and the air guide duct can play an obvious air guiding role.

[0091] Furthermore, the structure of the air guide housing is adapted to the structure of the second air outlet housing 12, and the cross-sectional structure of the air guide housing is adapted to the structure of the air outlet 23. When the air guide plate 13 is in the first working state, the air guide housing is in the third working state. When the air guide plate 13 is in the second working state, the air guide housing is in the fourth working state. Specifically, the air guide housing is a U-shaped structure, with the open end of the air guide housing facing the first air outlet housing 11. When the air guide housing is located between the air outlet 23 and the first wind shield 14, the air in the first air outlet duct 111 can enter the second air outlet duct 121.

[0092] In this way, the wind guide plate 13, the first wind shield plate 14 and the air guide duct guide the air flow throughout the entire process, so that more wind is discharged horizontally or obliquely downward, thereby increasing the air output.

[0093] While the exemplary embodiments of the present disclosure have been specifically illustrated and described above, it should be understood that the present disclosure is not limited to the detailed structures, configurations, or implementations described herein; rather, the present disclosure is intended to encompass various modifications and equivalent configurations within the spirit and scope of the appended claims.
