[0002] In the related art, a porous air guiding plate is used to replace the traditional non-porous air guiding plate. In the normal air supply mode, the porous air guiding plate opens the air outlet to achieve normal air supply. In the low draft air supply mode, the porous air guiding plate closes the air outlet, and air is supplied through the through holes on the porous air guiding plate, which can well reduce the blowing feeling of people and achieve low draft indoor air supply. However, due to the large air resistance of the porous air guiding plate, the air volume of the indoor unit of the air conditioner is small in the low draft air supply mode, and the low draft cooling capacity is poor in the low draft cooling mode, resulting in poor comfort of the human body. Summary of the Invention

[0020] In one embodiment, at least two adjacent air deflectors are spaced apart in the first direction.

[0021] Alternatively, any two adjacent air deflectors are directly connected in the first direction.

[0022] In one embodiment, multiple through holes are provided on at least one air deflector.

[0064] The present invention provides an air conditioner indoor unit.

[0065] In an embodiment of the present invention, as Figures 1 - 6 shown, the air conditioner indoor unit 10 includes a housing 200, a heat exchanger 300, a blower wheel 400, and a wind guiding device 500.

[0066] The housing 200 is provided with an air inlet 202 and an air outlet 204.

[0067] Both the heat exchanger 300 and the blower wheel 400 are disposed inside the housing 200. Under the action of the blower wheel 400, indoor air can enter the housing 200 from the air inlet 202, exchange heat with the heat exchanger 300, and then be discharged into the room through the air outlet 204, thereby realizing the adjustment of the indoor temperature (cooling or heating).

[0068] The wind guiding device 500 is disposed at the air outlet 204 and can guide the airflow flowing out from the air outlet 204.

[0069] In this embodiment, the wind guiding device 500 includes a plurality of wind guiding plates 510. The plurality of wind guiding plates 510 are sequentially connected in a first direction (in this embodiment, the first direction is the left-right direction), and the wind guiding directions of at least two wind guiding plates 510 are different.

[0070] In the above-mentioned air conditioner indoor unit 10, the air flow flowing out from the air outlet 204 can be guided by multiple air deflector plates 510 to at least two different orientations, so that the air flow flowing out from the air outlet 204 can be guided to at least two different areas in the room. When the air flow rate at the air outlet 204 is constant, compared with the traditional way of guiding the air flow in a single direction, guiding the air flow at the air outlet 204 from at least two different orientations can reduce the wind feeling of the air flow in each orientation, thereby improving the comfort of people in different orientations at the same time. And the air flow blowing into the room is the sum of the air flows in different orientations, so that the total air output of the air conditioner indoor unit 10 can be relatively large. Therefore, the above-mentioned air conditioner indoor unit 10 has a relatively low wind feeling and a relatively high air output at the same time.

[0071] In this embodiment, as Figures 7 - 12 shown, the air guiding device 500 has an air guiding position. When the air guiding device 500 is in the air guiding position, the air guiding device 500 is spaced from the air outlet 204 in the air outlet direction of the air outlet 204. In this way, it is very convenient for the air flow to be respectively guided from at least two different orientations through multiple air deflector plates 510, and it can be avoided that the air guiding device 500 is too close to the air outlet 204, resulting in too much attenuation of the air volume and affecting the noise value.

[0072] In this embodiment, as Figures 13 - 18 shown, the air guiding device 500 also has a storage position. When the air guiding device 500 is in the storage position, the air guiding device 500 is located inside the air outlet 204. In this way, when the air guiding device 500 is not needed to guide the air, the air guiding device 500 can be stored, so that the occupied space of the air conditioner indoor unit 10 is relatively small. Among them, when the air conditioner indoor unit 10 does not need to work, at this time, the air guiding device 500 is not needed to guide the air.

[0073] In this embodiment, as Figures 1 - 6 shown, the air conditioner indoor unit 10 further includes a first driving mechanism 600. The first driving mechanism 600 is arranged on the housing 200 and is connected to the air guiding device 500. The first driving mechanism 600 is used to drive the air guiding device 500 to switch between the storage position and the air guiding position.

[0074] In this embodiment, the first driving mechanism 600 includes a motor 610, a gear 620 and a push rod 630. The motor 610 is arranged on the housing 200. The gear 620 is arranged on the motor 610. A rack 632 is arranged on the push rod 630. The rack 632 meshes with the gear 620. The push rod 630 is connected to the air guiding device 500. In this way, the first driving mechanism 600 can drive the air guiding device 500 to switch between the storage position and the air guiding position.

[0075] In this embodiment, there are two first driving mechanisms 600, and the two first driving mechanisms 600 are arranged at intervals along the first direction. The push rods 630 of the two first driving mechanisms 600 are respectively connected to both ends of the air guiding device 500. In this way, the switching of the air guiding device 500 between the storage position and the air guiding position can be made more stable.

[0076] In this embodiment, the air guiding device 500 can also rotate around a rotating shaft parallel to the first direction. In this way, it can prevent each air guiding plate 510 from only guiding a fixed area, resulting in either some areas being too cold or some areas being too hot. When the air guiding device 500 rotates, the air guiding plates 510 can disperse the air, making the air more disordered and gentle, and further reducing the sense of wind.

[0077] In this embodiment, the air guiding device 500 can rotate periodically around a rotating shaft parallel to the first direction. In this way, the air flow can be sent to the required area periodically, further improving the comfort. Specifically, in some embodiments, the periodic rotation of the air guiding device 500 means that within a certain period of time, the air guiding device 500 rotates for a first preset time, stops rotating for a second preset time, rotates for the first preset time again, and then stops rotating for the second preset time again, and so on. In some embodiments, the periodic rotation of the air guiding device 500 means that within a certain period of time, the air guiding device 500 rotates clockwise by a first preset angle, rotates counterclockwise by a second preset angle, rotates clockwise by the first preset angle again, and then rotates counterclockwise by the second preset angle again, and so on.

[0078] In this embodiment, the air conditioner indoor unit 10 further includes a second driving mechanism 700. The second driving mechanism 700 is arranged on the push rod 630 and is connected to the air guiding device 500. The second driving mechanism 700 is used to drive the air guiding device 500 to rotate. Specifically, in this embodiment, the second driving mechanism 700 includes a motor arranged at the end of the push rod 630.

[0079] In this embodiment, the air conditioner indoor unit 10 further includes an outer air guiding plate 800. The outer air guiding plate 800 is arranged at the air outlet 204 and can open or close the air outlet 204.

[0080] In this embodiment, as Figures 1 - 6 shown, when the outer air guiding plate 800 closes the air outlet 204, the air guiding device 500 is in the storage position and is located in the space formed by the enclosure of the outer air guiding plate 800 and the housing 100. In this way, the inside of the air conditioner indoor unit 10 can be prevented from being affected by the external environment.

[0081] In this embodiment, as Figures 7 - 12 shown, when the outer air guiding plate 800 opens the air outlet 204 and the air guiding device 500 is in the air guiding position, the air guiding device 500 can extend out of the panel of the housing 100 with the air outlet 204.

[0082] In this embodiment, the above-mentioned air conditioner indoor unit 10 is a wall-mounted air conditioner indoor unit. After the wall-mounted air conditioner indoor unit is hung on the wall, when the user faces the wall-mounted air conditioner indoor unit 10, the above-mentioned first direction is the left-right direction of the air conditioner indoor unit 10. The air outlet 204 is located at the lower part of the front panel of the housing 100, and the lower edge of the outer air deflector 800 is rotatably connected to the inner wall below the air outlet 204. When the outer air deflector 800 opens the air outlet 204, the upper edge of the outer air deflector 800 moves downward.

[0083] In this embodiment, the outer air deflector 800 is arc-shaped.

[0084] In this embodiment, any two adjacent air deflectors 510 are directly connected in the first direction. In this way, it is very conducive to forming the air guiding device 500. Specifically, in this embodiment, multiple air deflectors 510 are integrally formed.

[0085] In other embodiments, at least two adjacent air deflectors 510 are spaced in the first direction. At this time, multiple air deflectors 510 can be arranged on the same support frame, and the multiple air deflectors 510 are indirectly connected in sequence in the first direction through the support frame. The gap between two adjacent air deflectors 510 can let out air and guide the air, so as to be more conducive to dispersing the air outlet and reducing the wind feeling.

[0086] In this embodiment, the air guiding directions of at least 10 air deflectors 510 are different. That is, the number of air deflectors 510 is greater than or equal to 10. At this time, the air flow flowing out of the air outlet 204 can be guided to 10 different directions by 10 air deflectors 510, and 3D stereo air outlet can also be realized.

[0087] Specifically, in this embodiment, the number of air deflectors 510 is less than or equal to 30. Specifically, in this embodiment, the number of air deflectors 510 is 13.

[0088] In this embodiment, the air guiding directions of multiple air deflectors 510 are all different. The air wheel 400 is a cross-flow air wheel. The air wheel 400 extends along the first direction. The number of air deflectors 510 is greater than or equal to the number of sections of the impeller of the air wheel 400, and at least one air deflector 510 corresponds to each section of the impeller of the air wheel 400.

[0089] Among them, the cross-flow air wheel is composed of one section of impeller after another. At least one air deflector 510 corresponds to each section of the impeller of the cross-flow air wheel, so that the air outlet of each section of the impeller of the cross-flow air wheel will be guided to different areas in the room. And the total air output of the cross-flow air wheel is limited, which is equal to the sum of the air outputs of multiple impellers, so that the wind feeling can be weakened.

[0090] In this embodiment, at least one air deflector 510 is arc-shaped. The arc-shaped air deflector 510 can guide air using the Coanda effect, which is very beneficial for air guiding.

[0091] In this embodiment, multiple air deflectors 510 are all arc-shaped. In this way, by setting parameters such as the radius corresponding to the air deflector 510, the central angle corresponding to the air deflector 510, and the tilt angle of the air deflector 510, the air outlet directions of the multiple arc-shaped air deflectors 510 can be made different.

[0092] It can be understood that in other embodiments, multiple air deflectors 510 can also be all flat plates, and the tilt angles of the multiple flat-plate air deflectors 510 with respect to a certain reference plane are all different, so that the air outlet directions of the multiple flat-plate air deflectors 510 are all different. It can be understood that in other embodiments, several of the multiple air deflectors 510 are arc-shaped and several are flat plates.

[0093] In this embodiment, the centers of the multiple air deflectors 510 are all located on the same straight line, and this straight line is parallel to the first direction. In this way, when the air guiding device 500 can also rotate around a rotating shaft parallel to the first direction, it is very beneficial for the air guiding device 500 to disperse the air, making the air more disordered and gentle, and further reducing the wind feeling.

[0094] In this embodiment, the radii corresponding to the multiple air deflectors 510 are all the same. In this way, after the multiple air deflectors 510 are connected in sequence in the first direction, the air guiding device 500 can be made to be approximately cylindrical, which is very convenient for manufacturing the corresponding diameter of the air guiding device 500.

[0095] The diameter corresponding to the air guiding device 500 is adapted to the opening width of the air outlet 204 in the second direction. If the diameter corresponding to the air guiding device 500 is too large or too small relative to the opening width of the air outlet 204 in the second direction, it is not conducive to both weakening the wind feeling and increasing the air output. The second direction intersects with the first direction. For this reason, in this embodiment, the diameter corresponding to the air deflector 510 is set to be 0.5 - 1.0 times the opening width of the air outlet 204 in the second direction, that is, the diameter corresponding to the air guiding device 500 is set to be 0.5 - 1.0 times the opening width of the air outlet 204 in the second direction, so as to balance weakening the wind feeling and increasing the air output. Specifically, in this embodiment, the second direction is perpendicular to the first direction. The above second direction is the front-back direction of the air conditioner indoor unit 10.

[0096] In this embodiment, the central angles corresponding to the multiple air deflectors 510 are all the same. In this way, the air guiding lengths of the multiple air deflectors 510 are all the same, which is more conducive to controlling the air guiding direction and is also more convenient for manufacturing the air guiding device 500.

[0097] In this embodiment, the central angle corresponding to the air deflector 510 is 30° - 150°. When the radius corresponding to the air deflector 510 remains unchanged, if the central angle corresponding to the air deflector 510 is too large, it will cause excessive occlusion of the air outlet 204 by the air deflector 510. In particular, the larger the number of the air deflectors 510, the greater the occlusion of the air outlet 204 by the air guiding device, which is not conducive to improving the air volume of the air conditioner indoor unit 10. If the central angle corresponding to the air deflector 510 is too small, it is not conducive to guiding the air flow to the preset direction. Considering the above factors, the central angle corresponding to the air deflector 510 is set to 30° - 150°. Specifically, in this embodiment, the central angle corresponding to the air deflector 510 is 90° - 120°. More specifically, in this embodiment, the central angle corresponding to the air deflector 510 is 112°.

[0098] In this embodiment, as Figure 7 shown, among two adjacent air deflectors 510, each air deflector 510 has a protruding portion 512 relative to the other air deflector 510. The protruding portion 512 of each air deflector 510 protrudes beyond the end face of the other air deflector 510.

[0099] Among three adjacent air deflectors 510, the three air deflectors 510 are respectively a first air deflector 510a, a second air deflector 510b, and a third air deflector 510c that are sequentially connected. The protruding portion 512 that the second air deflector 510b has relative to the first air deflector 510a is a first protruding portion 512a, and the protruding portion 512 that the third air deflector 510c has relative to the second air deflector 510b is a second protruding portion 512b. The second protruding portion 512b protrudes beyond the first protruding portion 512a.

[0100] In this way, a stepped structure can be formed at both side edges of the air guiding device 500 in the first direction, where each protruding portion 512 is a step. The stepped structure can form an air outlet gap with the edge of the air outlet 204, further reducing the occlusion of the air outlet 204 by the air guiding device 500 and improving the air volume of the air conditioner indoor unit 10. Moreover, in this way, even if the central angles corresponding to multiple air deflectors 510 are the same and the radii corresponding to multiple air deflectors 510 are the same, the air outlet directions of multiple air deflectors 510 can be different. And

[0101] In this embodiment, the central angles corresponding to the protruding portions 512 of multiple air deflectors 510 are the same. In this way, the air outlet can be more regular.

[0102] In this embodiment, the central angle corresponding to the protruding portion 512 is 0.2 - 0.6 times the central angle corresponding to the air deflector 510. If the central angle corresponding to the protruding portion 512 is too large, the air outlet gap formed between the stepped structure and the edge of the air outlet 204 will be too large, while if the central angle corresponding to the protruding portion 512 is too small, the air outlet gap formed between the stepped structure and the edge of the air outlet 204 will be too small. Either an overly large or overly small air outlet gap is not conducive to balancing the reduction of the wind feeling and the increase of the air volume. To balance the reduction of the wind feeling and the increase of the air volume, the central angle corresponding to the protruding portion 512 is set to be 0.2 - 0.6 times the central angle corresponding to the air deflector 510. Specifically, in this embodiment, the central angle corresponding to the protruding portion 512 is 0.3 - 0.4 times the central angle corresponding to the air deflector 510.

[0103] In this embodiment, the air guiding device 500 further includes two connecting plates 520. Multiple air deflectors 510 are all located between the two connecting plates 520, and the air deflectors 510 adjacent to the connecting plates 520 are connected to the connecting plates 520. Among them, at least one of the two connecting plates 520 is provided with ventilation holes 522. In this way, the two ends of the air guiding device 500 can also discharge air, and the discharged air can be scattered to reduce the wind feeling. Specifically, in this embodiment, the two connecting plates 520 are both grille plates.

[0104] In this embodiment, the two connecting plates 520 are both circular. The radius corresponding to the air deflector 510 is the same as the radius of the connecting plates 520, and the center of the circle corresponding to the air deflector 510 and the center of the circle of the connecting plates 520 are located on the same straight line. In this way, the integrity of the air guiding device 500 can be made better.

[0105] In this embodiment, at least one air deflector 510 is provided with through holes. In this way, air can be discharged through the through holes on the air deflector 510, thereby further reducing the blockage of the air outlet 204 by the air guiding device 500, increasing the air volume of the air conditioner indoor unit 10, and the through holes can reduce the wind feeling of the air discharged through the air deflector 510.

[0106] In this embodiment, multiple air deflectors 510 are all provided with through holes. In this embodiment, the aperture of the through holes is 2 - 10 millimeters.

[0107] In this embodiment, an air conditioner is further provided. The air conditioner includes the above-mentioned air conditioner indoor unit 10 and an air conditioner outdoor unit, and the air conditioner outdoor unit is connected to the air conditioner indoor unit through a refrigerant pipe.

[0108] The above-mentioned air conditioner indoor unit 10 is a wall-mounted air conditioner indoor unit. When the wall-mounted air conditioner indoor unit is hung on the wall and a user is facing the hanging air conditioner indoor unit 10, the above-mentioned first direction is the left-right direction of the air conditioner indoor unit 10, and the above-mentioned second direction is the front-back direction of the air conditioner indoor unit 10.

[0109] In this embodiment, the above-mentioned air conditioner indoor unit 10 blows a limited amount of air to a sufficient space and area in the room, so that the total amount of air in each range is limited, and then the wind speed at each position is limited. Taking the above-mentioned wall-mounted air conditioner indoor unit with an air volume of 600 m3 / h as an example, the effect of a wind speed less than 0.3 m / s can be achieved. After the wind speed is small enough, the discomfort caused by the impact on the human body will be weakened, achieving the effect of no wind feeling in the whole room. Specifically, in this embodiment, at 3.0 m (the distance from the air outlet 204 of the air conditioner indoor unit 10 is 3.0 m), the wind speed is less than 0.3 m / s, and at 2.5 m, the wind speed is less than 0.1 m / s.

[0110] The above are only the optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
