Description

Technical Field

[0001] The present invention belongs to the technical field of air treatment, and particularly relates to a cabinet-type air conditioner indoor unit. Background Art

[0002] In the existing cabinet-type air conditioner indoor unit, an air duct is formed inside the housing, and an air outlet communicating with the air duct is formed on the upper side of the side wall of the housing. The air outlet is located above the air duct. A wind deflector is arranged in the air duct. By adjusting the inclination angle of the wind deflector, the air in the air duct can pass through the wind deflector and the air outlet to achieve air outlet in different directions. When the indoor unit is in the closed state, there is no component that can close the air outlet. On the one hand, the components inside the housing can be seen through the air outlet, which affects the appearance of the indoor unit. On the other hand, the dust in the room can enter the air duct through the air outlet and then deposit on the wind deflector. When the indoor unit is in the open state, the dust on the wind deflector will enter the room along with the air in the air duct, affecting the indoor air quality and reducing the user experience. Summary of the Invention

[0003] In view of this, the present invention provides a cabinet-type air conditioner indoor unit to solve the problems in the prior art that the open air outlet affects the appearance of the indoor unit, and the dust deposited on the wind deflector when the indoor unit is in the closed state causes low air quality discharged from the air outlet when the indoor unit is in the open state.

[0004] The present invention provides a cabinet-type air conditioner indoor unit, including a housing and an air outlet mechanism. A main air duct is formed inside the housing, and an air outlet is formed on the side wall of the housing. The air outlet is located above the main air duct.

[0048] In the existing cabinet-type air conditioner indoor unit, when the indoor unit is in the closed state, there is a lack of a component that can close the air outlet. On the one hand, the components inside the housing can be seen through the air outlet, affecting the appearance of the indoor unit; on the other hand, indoor dust can enter the air duct through the air outlet and then deposit on the air deflector; when the indoor unit is in the open state, the dust on the air deflector will enter the room with the air in the air duct, affecting the indoor air quality and reducing the user experience;

[0049] The present invention creatively provides a cabinet-type air conditioner indoor unit, which includes a housing and an air outlet mechanism. A main air duct is formed inside the housing, and an air outlet is formed on the side wall of the housing. The air outlet is located above the main air duct. The air outlet mechanism is arranged in the main air duct and close to the air outlet. The air outlet mechanism includes an air outlet housing and a wind guiding housing. The air outlet housing encloses an air outlet duct. The main air duct, the air outlet duct and the air outlet are connected in sequence. The structure of the wind guiding housing is adapted to the structure of the air outlet duct, and the wind guiding housing is rotatably arranged on the air outlet housing. The wind guiding housing includes a wind guiding wall. When the wind guiding housing is in the closed working position, the wind guiding wall closes the air outlet end of the air outlet duct, so that the air outlet end of the air outlet duct is not communicated with the air outlet, ensuring the aesthetics and integrity of the appearance of the indoor unit, and preventing indoor dust from entering the air outlet duct through the air outlet, solving the problems that the air quality discharged from the air outlet is low due to dust deposition on the air guiding plate when the indoor unit is in the closed state. When the wind guiding housing is in the open working position, the wind guiding wall partially or completely opens the air outlet end of the air outlet duct, so that the air outlet end of the air outlet duct is communicated with the air outlet, and the air in the air outlet duct can be discharged through the wind guiding wall and the air outlet. The rotation angle of the wind guiding housing can be adjusted according to the air outlet requirement to realize air outlet in different directions.

[0050] Embodiment 1

[0051] As Figure 1 and Figure 2 shown, this embodiment provides a cabinet-type air conditioner indoor unit. The cabinet-type air conditioner indoor unit includes a housing and an air outlet mechanism. A main air duct is formed inside the housing, and an air outlet is formed on the side wall of the housing. The air outlet is located above the main air duct. The air outlet mechanism is arranged in the main air duct and close to the air outlet. The air outlet mechanism includes:

[0052] An air outlet housing that encloses an air outlet duct. The air inlet end of the air outlet duct is communicated with the main air duct, and the air outlet end of the air outlet duct is communicated with the air outlet.

[0053] A wind guiding housing 14, whose structure is adapted to the structure of the air outlet duct, and the wind guiding housing 14 is rotatably arranged on the air outlet housing. The wind guiding housing 14 has a closed working position and an open working position, and the wind guiding housing 14 includes a wind guiding wall 141.

[0054] As Figure 3a shown, when the wind guiding housing 14 is in the closed working position, the wind guiding wall 141 closes the air outlet end of the air outlet duct, so that the air outlet end of the air outlet duct is not communicated with the air outlet, blocking the air outlet end of the air outlet duct, ensuring the aesthetics and integrity of the appearance of the indoor unit; preventing indoor dust or rodents from entering the air outlet duct and the main air duct through the air outlet, and avoiding the problem that the air quality discharged from the air outlet is low due to dust deposition on the air guiding plate 13 when the indoor unit is in the closed state. As Figure 3b and Figure 3cAs shown, when the air guide housing 14 is in the open working position, the air guide wall 141 partially or completely opens the air outlet end of the air outlet duct, connecting the air outlet end of the air outlet duct to the air outlet. The air in the air outlet duct can be discharged through the air guide wall 141 and the air outlet. By adjusting the rotation angle of the air guide housing 14, air can be discharged in different directions.

[0055] To address the problem that the air outlet cannot achieve downward air discharge, in this embodiment, it is proposed that the open working position includes a downward air discharge working position and an upward air discharge working position;

[0056] As Figure 3b shown, when the air guide housing 14 is in the downward air discharge working position, the lower edge of the air guide wall 141 away from the air outlet end of the air outlet duct causes the air guide wall 141 to partially open the air outlet end of the air outlet duct, and the air in the air outlet duct can be discharged downward through the air outlet;

[0057] As Figure 3c shown, when the air guide housing 14 is in the upward air discharge working position, the air guide wall 141 is away from the air outlet end of the air outlet duct, causing the air guide wall 141 to completely open the air outlet end of the air outlet duct, and the air in the air outlet duct can be discharged upward through the air outlet;

[0058] When the air guide housing 14 rotates between the upward air discharge working position and the downward air discharge working position, the air in the air outlet duct can sweep up and down through the air outlet;

[0059] The guiding effect of the air guide wall 141 is obvious, with little loss of air volume and a large adjustable range of air outlet direction. When the air guide housing 14 is in the downward air discharge working position, the air in the air outlet duct can be discharged downward through the air outlet, achieving short-distance air supply and gentle air supply, enabling users to feel the breeze. When the air guide housing 14 is in the upward air discharge working position, the air in the air outlet duct can be discharged upward through the air outlet, achieving long-distance air supply. It solves the problem that downward air guiding cannot be achieved when the air outlet is above the main air duct, and solves the problem of a narrow adjustable range of air outlet direction; it can timely adjust the temperature nearby with high adjustment accuracy; it prevents the problem that users will feel uncomfortable when strong cold air blows directly at them.

[0060] To address the problem of a narrow adjustable range of the air outlet direction of the air outlet, in this embodiment, it is proposed that the air outlet housing includes a first air outlet housing 11 and a second air outlet housing 12. The cross-section of the first air outlet housing 11 is square, and the first air outlet housing 11 encloses a first air outlet duct 111, which extends in the vertical direction; the second air outlet housing 12 is arranged on the top of the first air outlet housing 11, and the cross-section of the second air outlet housing 12 is U-shaped. The second air outlet housing 12 encloses a second air outlet duct 121, and the opening of the second air outlet housing 12 faces the air outlet end of the first air outlet duct 111. The second air outlet duct 121 extends in the horizontal direction; the main air duct, the first air outlet duct 111, the second air outlet duct 121, and the air outlet are connected in sequence;

[0061] The air outlet end of the first air duct 111 is rotatably provided with a wind deflector 13. When the wind deflector 13 rotates, it can open or close the air outlet end of the first air duct 111. The second air duct 121 is rotatably provided with a wind guiding shell 14. When the wind guiding shell 14 rotates, the wind guiding wall 141 can open or close the air outlet end of the second air duct 121.

[0062] As Figure 3a shown, when the cabinet-type air conditioner indoor unit needs to be closed, the wind deflector 13 is used to close the air outlet end of the first air duct 111 and the wind guiding shell 14 is in the closed working position.

[0063] As Figure 3b shown, when the cabinet-type air conditioner indoor unit needs to blow air downward, the wind deflector 13 is used to open the air outlet end of the first air duct 111 and face the air outlet, and the wind guiding shell 14 is in the downward air blowing working position.

[0064] As Figure 3c shown, when the cabinet-type air conditioner indoor unit needs to blow air upward, the wind deflector 13 is used to open the air outlet end of the first air duct 111 and rotate reciprocally, and the wind guiding shell 14 is in the upward air blowing working position, and the wind guiding wall 141 does not block the air blown out from the second air duct 121.

[0065] When the cabinet-type air conditioner indoor unit needs to sweep the air up and down, the wind deflector 13 is used to open the air outlet end of the first air duct 111 and face the air outlet, and the wind guiding shell 14 reciprocates between the upward working position and the downward air blowing working position.

[0066] In summary, according to actual needs, the wind deflector 13 and the wind guiding shell 14 can be in different positions to realize large-range and multi-directional air supply, meet different needs of users, and the structure and control process are simple.

[0067] Specifically, there are multiple wind deflectors 13, and the multiple wind deflectors 13 are sequentially arranged at the air outlet end of the first air duct 111 along the width direction of the first air duct 111. The multiple wind deflectors 13 can be rotated independently or synchronously. The multiple wind deflectors 13 rotate reciprocally to achieve the function of sweeping the air up and down.

[0068] Aiming at the problems of the complex structure, large occupied space and unclear air guiding effect of the wind guiding shell 14, this embodiment proposes that the wind guiding shell 14 further includes a support wall 142. One end of the support wall 142 is connected to the wind guiding wall 141, and the other end of the support wall 142 is rotatably arranged on the side wall of the second air duct 121, and the rotation axis of the support wall 142 is perpendicular to the side wall of the second air duct 121.

[0069] When the support wall 142 rotates, it can drive the wind guiding wall 141 to rotate, and then the wind guiding shell 14 is in the closed working position or the downward air blowing working position or the upward air blowing working position.

[0070] Specifically, the support wall 142 rotates to make the air guiding wall 141 rotate towards the direction close to the air outlet end of the second air outlet duct 121. When the air guiding wall 141 contacts the lower edge of the air outlet, the air guiding housing 14 is in the closed working position, and the air guiding wall 141 can close the air outlet end of the second air outlet duct 121; the support wall 142 rotates to make the air guiding wall 141 rotate away from the air outlet end of the second air outlet duct 121. When the air guiding wall 141 separates from the lower edge of the air outlet and a part of the air guiding wall 141 closes the air outlet end of the second air outlet duct 121, the air guiding housing 14 is in the downward air outlet working position, and the air guiding wall 141 can partially open the air outlet end of the second air outlet duct 121; the support wall 142 rotates to make the air guiding wall 141 rotate away from the air outlet end of the second air outlet duct 121. When the air guiding housing 14 is completely inside the second air outlet duct 121, the air guiding housing 14 is in the upward air outlet working position.

[0071] Furthermore, the support wall 142 includes a first support wall and a second support wall. The first support wall and the second support wall are respectively located on both sides of the air guiding wall 141, and the first support wall, the second support wall and the air guiding wall 141 form a U-shaped structure;

[0072] The second air outlet duct 121 includes an air outlet duct top wall, a first side wall of the air outlet duct and a second side wall of the air outlet duct; the first support wall is arranged in parallel with the first side wall of the air outlet duct and the first support wall is rotatably arranged on the first side wall of the air outlet duct; the second support wall is arranged in parallel with the second side wall of the air outlet duct and the second support wall is rotatably arranged on the second side wall of the air outlet duct;

[0073] When the air guiding housing 14 is in the downward air outlet working position, a part of the air guiding wall 141 closes the air outlet end of the second air outlet duct 121, and another part of the air guiding wall 141 is located below the air outlet duct top wall;

[0074] When the air guiding housing 14 is in the upward air outlet working position, the air guiding wall 141 is located below the air outlet duct top wall.

[0075] Embodiment 2

[0076] Different from Embodiment 1, this embodiment proposes that there are multiple air guiding housings 14. Each air guiding housing 14 can rotate independently and each air guiding housing 14 can rotate relative to the same intermediate axis; each air guiding housing 14 is a U-shaped structure and each air guiding housing 14 includes an air guiding wall and two support walls; along the radial direction of the intermediate axis of the air guiding housing 14, the multiple air guiding housings 14 have different sizes and the multiple air guiding housings 14 are arranged in sequence; specifically, the multiple air guiding housings 14 are rotatably arranged on the second air outlet housing 12, the support walls are parallel to the side walls of the second air outlet housing 12, and the intermediate axis is perpendicular to the side walls of the second air outlet housing 12;

[0077] When the cabinet-type air conditioner indoor unit needs to blow air, along the air outlet direction of the air outlet duct, multiple air guide shells 14 are rotated by different angles in sequence. The multiple air guide shells 14 enclose an air guide cavity, and the air in the air outlet duct can be discharged through the air guide cavity and the air outlet. Specifically, when the multiple air guide shells 14 are sleeved together, the length of the air guide cavity is the smallest along the air outlet direction of the second air outlet duct 121; among the multiple air guide shells 14, when the rotation distance between the air guide shell 14 close to the air outlet and the air guide shell 14 close to the air inlet end of the second air duct 121 is the largest, the length of the air guide cavity is the largest along the air outlet direction of the second air outlet duct 121.

[0078] Preferably, among the multiple air guide shells 14, the radial dimension of the air guide shell 14 close to the air outlet is the smallest, which can guide the air in the second air outlet duct 121, and the air outlet volume is large; the radial dimension of the air guide shell 14 close to the air inlet end of the second air outlet duct 121 is the largest, which plays a certain role in gathering the air; the air in the first air outlet duct 111 can directly enter the air guide cavity, and under the action of the air guide cavity, the air can be discharged; by adjusting the rotation angles of the multiple air guide cavities, different air guide paths can be formed to achieve different air guide effects and meet different air outlet requirements.

[0079] Aiming at the problem of poor air guide effect of the multiple air guide cavities, in this embodiment, along the air outlet direction of the air outlet duct, the air guide cavity is in an arc-shaped structure; the air inlet end of the air guide cavity is close to the air inlet end of the air outlet duct, and the air outlet end of the air guide cavity is close to the air outlet end of the air outlet duct.

[0080] Furthermore, two adjacent air guide shells 14 are in sliding fit in the circumferential direction of the middle shaft and are hermetically connected by a flexible member, so that the two adjacent air guide shells 14 can rotate relative to each other stably.

[0081] Aiming at the problem that the fixed position of the air guide shell 14 results in a small adjustable range of the air outlet volume, in this embodiment, the air outlet mechanism further includes a positioning member, which is slidably arranged on the side wall of the air outlet duct and the positioning member forms a card slot;

[0082] The side wall of the air outlet duct is formed with a shaft hole, a middle shaft is arranged in the shaft hole and the shaft hole is a long strip-shaped hole, and the extending direction of the shaft hole is different from the sliding direction of the positioning member;

[0083] When the positioning member slides to make the card slot cooperate with the shaft hole, the middle shaft can be fixed at any position in the shaft hole; according to the actual air outlet needs, the position of the middle shaft can be adjusted to expand the air guide range of the air guide shell 14, ensure the air outlet volume, and can realize a large-range adjustment of the air outlet direction to meet different air outlet needs.

[0084] Furthermore, the shaft hole extends along the circumferential direction of the middle shaft, and the positioning member slides along the radial direction of the middle shaft.

[0085] Specifically, the positioning member is slidably arranged on the side wall of the second air outlet duct, and the side wall of the second air outlet duct is formed with a shaft hole;

[0086] The air guide housing 14 is rotatably arranged on the air outlet housing. When the indoor unit needs to be closed, the air guide housing 14 is in the closed working position, and the air guide wall closes the air outlet end of the air outlet duct, ensuring the aesthetics and integrity of the appearance of the indoor unit; dust in the room cannot enter the air outlet duct through the air outlet, solving the problems such as dust deposition on the air deflector when the indoor unit is in the closed state, resulting in low air quality discharged from the air outlet; when the indoor unit needs to discharge air, the air guide housing 12 is in the open working position, so that the air outlet end of the air outlet duct is communicated with the air outlet, and the air in the air outlet duct can be discharged through the air guide wall and the air outlet.

[0087] When the air guide housing 14 is in the downward air discharge working position, the air guide wall partially opens the air outlet end of the air outlet duct, and the air in the air outlet duct can be discharged downward through the air outlet; when the air guide housing 14 is in the upward air discharge working position, the air guide wall completely opens the air outlet end of the air outlet duct, and the air in the air outlet duct can be discharged upward through the air outlet.

[0088] Specifically, a plurality of air guide housings 14 are rotatably arranged on the second air outlet housing 12. When the indoor unit needs to be closed, the air guide housing 14 close to the air outlet is in the closed working position, and the air guide wall 141 of the air guide housing 14 closes the air outlet end of the second air outlet duct 121, ensuring the aesthetics and integrity of the appearance of the indoor unit; dust in the room cannot enter the second air outlet duct 121 through the air outlet, solving the problems such as dust deposition on the air deflector when the indoor unit is in the closed state, resulting in low air quality discharged from the air outlet.

[0089] When the indoor unit needs to exhaust air downward, the air guide housing 14 close to the air outlet is in the downward air discharge working position, and the air guide wall 141 of the air guide housing 14 partially opens the air outlet end of the second air outlet duct 121. Other air guide housings 14 rotate at different angles to form an air guide cavity, and the air in the second air outlet duct 121 can be discharged downward through the air guide cavity and the air outlet; by adjusting the rotation angles of these air guide housings, the air in the second air outlet duct 121 can be guided in different directions; when the indoor unit needs to exhaust air upward, when a plurality of air guide housings 14 are all in the upward air discharge working position, the air guide wall 141 completely opens the air outlet end of the second air outlet duct 121, and the air in the second air outlet duct 121 can be discharged upward through the air outlet.

[0090] In this application, the cabinet-type air conditioner indoor unit includes a housing and an air outlet mechanism. A main air duct is formed inside the housing, and an air outlet is formed on the side wall of the housing. The air outlet is located above the main air duct, and the air in the main air duct can be discharged upward or forward through the air outlet. The air outlet mechanism is arranged in the main air duct and close to the air outlet, and the air outlet mechanism includes an air outlet housing and a wind guiding housing. An air outlet duct is formed in the air outlet housing, and the main air duct, the air outlet duct, and the air outlet are connected in sequence. The wind guiding housing is rotatably arranged on the air outlet housing, and the wind guiding housing includes a wind guiding wall. When the wind guiding housing is in the closed working position, the wind guiding wall closes the air outlet end of the air outlet duct, so that the air outlet end of the air outlet duct is not communicated with the air outlet, ensuring the beauty and integrity of the appearance of the indoor unit, and preventing indoor dust from entering the air outlet duct through the air outlet, solving the problems that the air deflector will deposit dust when the indoor unit is in the closed state, resulting in low air quality discharged from the air outlet, etc. When the wind guiding housing is in the open working position, the wind guiding wall partially or completely opens the air outlet end of the air outlet duct, so that the air outlet end of the air outlet duct is communicated with the air outlet, and the air in the air outlet duct can be discharged through the wind guiding wall and the air outlet. According to the air outlet needs, the rotation angle of the wind guiding housing can be adjusted to realize air outlet in different directions. The guiding effect of the wind guiding wall is obvious, the air volume loss is small, and the adjustable range of the air outlet direction is large;

[0091] Specifically, the open working position includes a downward air outlet working position and an upward air outlet working position. When the wind guiding housing is in the downward air outlet working position, the lower edge of the wind guiding wall far away from the air outlet end of the air outlet duct makes the wind guiding wall partially open the air outlet end of the air outlet duct, and the air in the air outlet duct can be discharged downward through the air outlet, realizing short-distance air supply and gentle air supply, enabling users to feel the feeling of gentle breeze blowing, solving the problem that downward air guiding cannot be realized when the air outlet is located above the main air duct, and can timely adjust the temperature nearby with high adjustment accuracy; preventing the problem that users will feel uncomfortable when strong cold air blows directly at them. When the wind guiding housing is in the upward air outlet working position, the wind guiding wall is far away from the air outlet end of the air outlet duct, making the wind guiding wall completely open the air outlet end of the air outlet duct, and the air in the air outlet duct can be discharged upward through the air outlet, realizing long-distance air supply. When the wind guiding housing rotates between the upward air outlet working position and the downward air outlet working position, the air in the air outlet duct can sweep up and down through the air outlet; solving the problem of narrow adjustable range of the air outlet direction.

[0092] The above embodiments are applied to the cabinet-type air conditioner indoor unit. This application can also be applied to the wall-mounted indoor unit and other ventilation equipment. Through the wind guiding housing, the air outlet end of the air outlet duct can be closed, and the air in the air outlet duct can also be guided to different areas and different directions.

[0093] The above specifically shows and describes the exemplary embodiments of the present disclosure. It should be understood that the present disclosure is not limited to the detailed structures, setting methods or implementation methods described here; on the contrary, the present disclosure intends to cover various modifications and equivalent settings included in the spirit and scope of the appended claims.
