The invention provides an indoor unit of an air conditioner.

In the embodiment of the present invention, as shown in fig. 1 to 6, the indoor unit 10 of an air conditioner includes a casing 200, a heat exchanger 300, a wind wheel 400, and a wind guide device 500.

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

The heat exchanger 300 and the wind wheel 400 are both disposed in the housing 200. Under the action of the wind wheel 400, indoor air can enter the housing 200 from the air inlet 202, exchanges heat with the heat exchanger 300, and is discharged to the indoor through the air outlet 204, so that the indoor temperature can be adjusted (cooled or heated).

The air guiding device 500 is disposed at the air outlet 204 and can guide the air flow flowing out from the air outlet 204.

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

In the air conditioning indoor unit 10, the airflow flowing out of the outlet 204 can be guided by the plurality of air deflectors 510 to at least two different directions, so that the airflow flowing out of the outlet 204 can be guided to at least two different areas in the room. When the airflow at the air outlet 204 is fixed, compared with the traditional mode of leading the airflow out from a single direction, the airflow at the air outlet 204 is led out from at least two different directions, so that the wind sensation of the airflow in each direction can be reduced, and the comfort level of a human body in different directions can be improved at the same time. The total air output of the indoor unit 10 of the air conditioner is relatively large because the air flow blown into the room is the sum of the air flows in different directions. Therefore, the air conditioning indoor unit 10 has a lower wind sensation and a higher air output.

In the present embodiment, as shown in fig. 7 to 12, the air guiding device 500 has an air guiding position. When the air guiding device 500 is at the air guiding position, the air guiding device 500 and the air outlet 204 are spaced in the air outlet direction of the air outlet 204. Therefore, the air flow can be guided out from at least two different directions through the plurality of air deflectors 510 conveniently, and the air guiding device 500 can be prevented from being too close to the air outlet 204, so that the air flow is greatly attenuated, and the noise value is not influenced.

In the present embodiment, as shown in fig. 13 to 18, the air guide device 500 further has a storage position. When the air guiding device 500 is at the storage position, the air guiding device 500 is located in the air outlet 204. In this way, when the air guide device 500 is not required to guide air, the air guide device 500 can be housed, so that the occupied space of the air-conditioning indoor unit 10 is small. When the operation of the air-conditioning indoor unit 10 is not required, the air guide device 500 is not required.

In this embodiment, as shown in fig. 1 to 6, the indoor air conditioner unit 10 further includes a first driving mechanism 600. The first driving mechanism 600 is provided on the housing 200 and connected to the air guide device 500. The first driving mechanism 600 is used to drive the air guide device 500 to switch between the storage position and the air guide position.

In the present embodiment, the first driving mechanism 600 includes a motor 610, a gear 620, and a push rod 630. The motor 610 is provided on the housing 200. The gear 620 is provided on the motor 610. The push rod 630 is provided with a rack 632. The rack 632 is engaged with the gear 620. The push rod 630 is connected to the air guide device 500. In this way, the first driving mechanism 600 can drive the air guide device 500 to switch between the storage position and the air guide position.

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 two ends of the air guiding device 500. In this way, the air guide device 500 can be switched between the storage position and the air guide position more stably.

In this embodiment, the wind guiding device 500 can also rotate around a rotating shaft parallel to the first direction. In this manner, each air deflection 510 is prevented from being directed only to a fixed area, resulting in either some areas being too cold or some areas being too hot. When the air guide device 500 rotates, the air guide plate 510 can disperse air, so that the air can be more disordered and soft, and the wind sensation is further reduced.

In the present embodiment, the wind guide device 500 can periodically rotate around a rotation axis parallel to the first direction. Therefore, the airflow can be periodically sent to the required area, and the comfort is further improved. Specifically, in some embodiments, the periodic rotation of the wind guiding device 500 means that, within a certain period of time, the wind guiding device 500 rotates for a first preset time, stops rotating for a second preset time, rotates for the first preset time again, stops rotating for the second preset time, and so on. In some embodiments, the periodic rotation of the wind guiding device 500 means that, within a certain period of time, the wind guiding device 500 rotates clockwise by a first preset angle, rotates counterclockwise by a second preset angle, rotates clockwise by the first preset angle, rotates counterclockwise by the second preset angle, and so on.

In this embodiment, the indoor unit 10 further includes a second driving mechanism 700. The second driving mechanism 700 is disposed on the push rod 630 and 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 the present embodiment, the second driving mechanism 700 includes a motor provided at an end of the push rod 630.

In this embodiment, the indoor unit 10 further includes an external air deflector 800. The outer air deflector 800 is disposed at the air outlet 204 and can open or close the air outlet 204.

In the present embodiment, as shown in fig. 1 to fig. 6, when the outer wind deflector 800 closes the wind outlet 204, the wind guiding device 500 is located at the storage position and is located in a space enclosed by the outer wind deflector 800 and the casing 100. In this way, the inside of the indoor air conditioning unit 10 can be prevented from being affected by the external environment.

In the present embodiment, as shown in fig. 7 to 12, when the external air deflector 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 having the air outlet 204.

In this embodiment, the air-conditioning indoor unit 10 is a wall-mounted air-conditioning indoor unit. When the user is facing the wall-mounted indoor unit 10 after the wall-mounted indoor unit is mounted on the wall, the first direction is a left-right direction of the indoor unit 10. The air outlet 204 is located at the lower portion of the front panel of the casing 100, and the lower edge of the outer air guiding plate 800 is rotatably connected to the inner wall below the air outlet 204. When the outer wind deflector 800 opens the wind outlet 204, the upper edge of the outer wind deflector 800 moves downward.

In the present embodiment, the outer air guiding plate 800 has an arc shape.

In this embodiment, any two adjacent air deflectors 510 are directly connected in the first direction. Thus, the air guide device 500 is very advantageously formed. Specifically, in the present embodiment, the air deflectors 510 are integrally formed.

In other embodiments, at least two adjacent air deflectors 510 are spaced apart in the first direction. At this time, the plurality of air deflectors 510 can be arranged on the same support frame, and the plurality of air deflectors 510 are indirectly connected in sequence in the first direction through the support frame. And the gap between two adjacent air deflectors 510 can exhaust air and guide the air, thereby being more beneficial to scattering the exhaust air and reducing the wind sensation.

In this embodiment, the wind guiding directions of at least 10 wind deflectors 510 are different. I.e., the number of the air deflectors 510 is equal to or greater than 10. At this time, the airflow flowing out of the air outlet 204 can be guided to 10 different directions by the 10 air deflectors 510, and 3D stereoscopic air outlet can also be realized.

Specifically, in the present embodiment, the number of the air deflectors 510 is less than or equal to 30. Specifically, in the present embodiment, the number of the air deflectors 510 is 13.

In this embodiment, the wind guiding directions of the plurality of wind guiding plates 510 are different. The wind wheel 400 is a cross flow wind wheel. The wind rotor 400 extends in a first direction. The number of the air deflectors 510 is greater than or equal to the number of the sections of the impeller of the wind wheel 400, and each section of the impeller of the wind wheel 400 corresponds to at least one air deflector 510.

Wherein, the cross-flow wind wheel is composed of a section of impeller. Each section of impeller of the cross-flow wind wheel at least corresponds to one air deflector 510, so that the air outlet of each section of impeller of the cross-flow wind wheel can be guided to different areas in a room, the total air outlet quantity of the cross-flow wind wheel is limited and is equal to the sum of the air outlet quantities of a plurality of impellers, and the wind sensation can be weakened.

In the present embodiment, at least one wind deflector 510 has a circular arc shape. The arc-shaped air deflector 510 can guide air by utilizing the coanda effect, and is very favorable for guiding air.

In the present embodiment, each of the air deflectors 510 has an arc shape. In this way, the air outlet directions of the plurality of arc-shaped air deflectors 510 are different by setting parameters such as the radius corresponding to the air deflector 510, the central angle corresponding to the air deflector 510, and the inclination angle of the air deflector 510.

It can be understood that, in other embodiments, the plurality of flat air deflectors 510 may be all shaped like a flat plate, and the inclination angles of the plurality of flat air deflectors 510 with respect to a certain reference plane are different, so that the air outlet directions of the plurality of flat air deflectors 510 are different. It is understood that in other embodiments, the plurality of air deflectors 510 have a circular arc shape, and the plurality of air deflectors 510 have a flat plate shape.

In this embodiment, the centers of the plurality of wind deflectors 510 are all located on the same straight line, and the straight line is parallel to the first direction. So, when air ducting 500 can also be around the pivot rotation parallel with the first direction, do benefit to air ducting 500 very much and beat the wind, let wind can add unordered and soft more, further reduce the wind sense.

In this embodiment, the radii corresponding to the plurality of wind deflectors 510 are all the same. As described above, the plurality of air guide plates 510 are sequentially connected in the first direction, so that the air guide device 500 is substantially cylindrical, which is very convenient for manufacturing a diameter corresponding to the air guide device 500.

And the diameter corresponding to the air guiding device 500 is adapted to the opening width of the air outlet 204 in the second direction. The diameter of the air guiding device 500 corresponding to the opening width of the air outlet 204 in the second direction is too large or too small, which is not favorable for reducing the wind sensation and increasing the air output, and the second direction intersects with the first direction. Therefore, in the present embodiment, the diameter corresponding to the air deflector 510 is set to be 0.5 to 1.0 times of 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 to 1.0 times of the opening width of the air outlet 204 in the second direction, so as to both reduce the wind sensation and increase the air output. Specifically, in the present embodiment, the second direction is perpendicular to the first direction. The second direction is a front-rear direction of the air conditioning indoor unit 10.

In this embodiment, the central angles of the plurality of air deflectors 510 are all the same. Therefore, the air guide lengths of the air guide plates 510 are the same, so that the air guide direction can be controlled more conveniently, and the air guide device 500 can be manufactured more conveniently.

In the embodiment, the central angle of the wind deflector 510 is 30-150 °. Under the condition that the radius corresponding to the air deflector 510 is not changed, the too large central angle corresponding to the air deflector 510 may cause the too large shielding of the air deflector 510 to the air outlet 204, and particularly, the larger the number of the air deflectors 510 is, the larger the shielding of the air guiding device to the air outlet 204 is, which is unfavorable for increasing the air output of the indoor unit 10 of the air conditioner, while the too small central angle corresponding to the air deflector 510 is unfavorable for guiding the air outlet to the preset direction. Combining the above factors, the central angle of the wind deflector 510 is set to be 30-150 °. Specifically, in the present embodiment, the central angle of the wind deflector 510 is 90 ° to 120 °. More specifically, in the present embodiment, the central angle of the wind deflector 510 is 112 °.

In the present embodiment, as shown in fig. 7, in two adjacent air deflectors 510, each air deflector 510 has a protrusion 512 opposite to the other air deflector 510. The protrusion 512 of each air deflector 510 protrudes out of the end surface of the other air deflector 510.

Among the 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 which are sequentially connected. The protrusion 512 of the second air guiding plate 510b relative to the first air guiding plate 510a is a first protrusion 512a, the protrusion 512 of the third air guiding plate 510c relative to the second air guiding plate 510b is a second protrusion 512b, and the second protrusion 512b protrudes out of the first protrusion 512 a.

Thus, the two side edges of the air guiding device 500 in the first direction form a step-by-step structure, wherein each protruding portion 512 is a step. The step structure can form an air outlet gap with the edge of the air outlet 204, so that the shielding of the air guiding device 500 on the air outlet 204 is further reduced, and the air output of the indoor unit 10 of the air conditioner is increased. In addition, even if the central angles corresponding to the plurality of air deflectors 510 are the same, and the radii corresponding to the plurality of air deflectors 510 are the same, the air outlet directions of the plurality of air deflectors 510 are different. While

In the present embodiment, the central angles of the protrusions 512 of the plurality of wind deflectors 510 are the same. So, can make the air-out more regular.

In the embodiment, the central angle of the protrusion 512 is 0.2-0.6 times of the central angle of the air deflector 510. The central angle corresponding to the protrusion 512 is too large, the step structure may form too large air outlet gap with the edge of the air outlet 204, and the central angle corresponding to the protrusion 512 is too small, the step structure may form too small air outlet gap with the edge of the air outlet 204. The too large or too small air outlet gap is not favorable for reducing the wind feeling and improving the air outlet quantity, and in order to reduce the wind feeling and improve the air outlet quantity, the central angle corresponding to the protrusion part 512 is 0.2-0.6 times of the central angle corresponding to the air deflector 510. Specifically, in the present embodiment, the central angle of the protrusion 512 is 0.3-0.4 times the central angle of the air deflector 510.

In this embodiment, the wind guiding device 500 further includes two connecting plates 520. The plurality of air deflectors 510 are located between the two connecting plates 520, and the air deflectors 510 adjacent to the connecting plates 520 are connected with the connecting plates 520. At least one of the two connecting plates 520 is provided with a vent hole 522. Thus, the two ends of the air guiding device 500 can also be used for air outlet, and the air outlet can be scattered, so that the wind sensation is reduced. Specifically, in the present embodiment, the two connecting plates 520 are both grating plates.

In this embodiment, the two connection plates 520 are both circular. The radius corresponding to the air deflector 510 is the same as the radius of the connecting plate 520, and the center of the circle corresponding to the air deflector 510 and the center of the circle of the connecting plate 520 are located on the same straight line. In this way, the integrity of the air guide device 500 can be improved.

In the present embodiment, at least one air guiding plate 510 is provided with a through hole. Thus, the air can be discharged through the through holes of the air deflector 510, so that the shielding of the air guiding device 500 on the air outlet 204 is further reduced, the air output of the indoor unit 10 of the air conditioner is increased, and the through holes can reduce the wind sensation of the discharged air passing through the air deflector 510.

In the present embodiment, a plurality of air deflectors 510 are all provided with through holes. In this embodiment, the aperture of the through-hole is 2-10 mm.

In this embodiment, an air conditioner is further provided, where the air conditioner includes the air conditioning indoor unit 10 and an air conditioning outdoor unit, and the air conditioning outdoor unit is connected to the air conditioning indoor unit through a refrigerant pipe.

The indoor air conditioner 10 is a wall-mounted indoor air conditioner. When the wall-mounted indoor unit of an air conditioner is hung on a wall and a user faces the wall-mounted indoor unit of an air conditioner 10, the first direction is a left-right direction of the indoor unit of an air conditioner 10, and the second direction is a front-back direction of the indoor unit of an air conditioner 10.

In this embodiment, the air-conditioning indoor unit 10 allows the limited air volume to be blown to a sufficient space and area of the room, so that the total air volume in each range is limited, and the air speed at each position is limited. Taking the wall-mounted air conditioner indoor unit with the air volume of 600m3/h as an example, the effect that the air speed is less than 0.3m/s can be realized. After the wind speed is small enough, the uncomfortable feeling of flapping on the human body is weakened, and the effect that the whole room has no wind feeling is realized. Specifically, in the embodiment, the wind speed is less than 0.3m/s at 3.0m (the distance from the air outlet 204 of the indoor unit 10 of the air conditioner is 3.0m), and the wind speed is less than 0.1m/s at 2.5 m.
