In this specification, schematic representations of the above terms do not necessarily refer to the same embodiments or examples. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

The present invention provides an air conditioning indoor unit 10. The form of the air conditioning indoor unit 10 is not limited in any way, and the air conditioning indoor unit 10 may be a wall-mounted indoor unit, a vertical indoor unit, a window-type indoor unit, or other indoor units of various forms. Fig. 1 to 6 show an embodiment of a wall-mounted indoor unit.

Fig. 1 is a schematic front view of an air conditioning indoor unit 10 according to one embodiment of the present invention, fig. 2 is a schematic rear view of the air conditioning indoor unit 10 according to one embodiment of the present invention, and fig. 3 is a schematic cross-sectional view of the air conditioning indoor unit 10 according to one embodiment of the present invention, as shown in fig. 1 and 2, the air conditioning indoor unit 10 may generally include a cabinet 100 and an air deflector 210.

An air outlet duct 110 is formed in the casing 100, an air outlet 120 is formed on the surface of the casing 100, and the air outlet duct 110 is communicated with the air outlet 120. The wind deflector 210 is rotatably installed at the air outlet 120 for opening and closing the air outlet 120. When the air deflector 210 is fully closed, its inner side surface faces the air outlet 120, and its outer side surface faces away from the air outlet 120, where the inner side surface of the air deflector 210 is defined as the windward side and the outer side surface is defined as the leeward side. The air outlet duct 110 has a plurality of air outlet holes 112, and the air outlet holes 112 are configured to controllably outlet air toward the leeward side of the air deflector 210 after the air deflector 210 is opened.

With the structure, after the air deflector 210 is opened, each air outlet 112 can be controlled to outlet air towards the leeward side of the air deflector 210, so that the temperature difference between the leeward side and the windward side of the air deflector 210 is reduced, the condensation problem of the air deflector 210 is effectively prevented, the air pressure of the air outlet 112 is large, the air outlet 112 has a long air supply distance, the air supply range of the air conditioner is enlarged, the rapid adjustment of the indoor temperature is facilitated, and the use experience of a user is improved.

In one example, the air outlet 112 may be formed at a bottom wall of the air outlet duct 110 adjacent to the air outlet 120, and the plurality of air outlet 112 are arranged at intervals along the lateral direction of the casing 100. Thus, the air outlets 112 can blow air more uniformly toward the leeward side of the air deflector 210, so that the temperatures of the areas of the leeward side of the air deflector 210 tend to be uniform.

Further, since the air outlet 112 is formed on the bottom wall of the air outlet duct 110 adjacent to the air outlet 120, i.e. behind the air outlet 120, when the air deflector 210 completely closes the air outlet 120, the air outlet 112 is not exposed from the air outlet 120, so as to hide the air outlet 112, which is beneficial to improving the aesthetic appearance of the indoor unit 10.

Of course, in other examples, the air outlet 112 may be formed at or below the bottom of the enclosure 100 and controlled to outlet air toward the leeward side of the air deflector 210 after the air deflector 210 is opened.

In an alternative embodiment, an air inlet grille is formed at the top of the casing 100, an air inlet 130 is formed on the air inlet grille, an air outlet 120 is formed at the front side of the bottom of the casing 100, an air outlet duct 110 communicates with the air inlet 130 and the air outlet 120, a through-flow fan (not shown in the figure) is disposed in the air outlet duct 110, and an evaporator 300 is disposed at the rear side of the through-flow fan. Under normal conditions, after the cross-flow fan is started, indoor air enters the casing 100 through the air inlet 130 to exchange heat with the evaporator 300, and then is blown out from the air outlet 120 along the air outlet duct 110.

Further, a plurality of air inlet holes 111 may be formed in the air outlet duct 110 adjacent to the air duct bottom wall of the cross-flow fan, and the air inlet holes 111 and the air outlet holes 112 are in one-to-one correspondence and are communicated with each other through a connecting pipe 140.

Thus, after the cross-flow fan is started, the wind speed of the surrounding area is high, and part of the airflow in the air outlet duct 110 can be easily blown into the air inlet 111 and then blown out from the air outlet 112 under the guiding effect of the connecting pipe 140.

The invention ensures that the air quantity of the air outlet 112 is still provided by the cross-flow fan through the ingenious design of the air inlet 111 and the connecting pipe 140, and other independent flow-promoting devices are not needed to be additionally arranged to provide the air quantity for the air outlet 112.

The connecting pipe 140 can be designed with a small pipe diameter structure, so that a narrow pipe effect is generated, and the air speed of the air flow blown out from the air outlet 112 is larger, and the air supply distance is longer.

In one example, the connection tube 140 may be located below the duct bottom wall of the outlet duct 110. In this way, the connecting pipe 140 can be prevented from occupying the inner space of the air outlet duct 110 and blocking the smooth air outlet of the air outlet.

In other examples, the connection pipe 140 may be located inside the air outlet duct 110, in which case the air inlet 111 is not required to be disposed on the bottom wall of the duct, and part of the air flow generated by the through-flow fan may directly enter the connection pipe 140 through the inlet end of the connection pipe 140, and the outlet end of the connection pipe 140 is connected to the air outlet 112.

Referring to fig. 1 and 3, the air inlet hole 111 and the air outlet hole 112 are both opened on the air duct bottom wall of the air outlet duct 110, and the air inlet hole 111 is adjacent to the cross-flow fan, the air outlet hole 112 is adjacent to the air outlet 120, and the air outlet hole 112 is located at the front lower side of the air inlet hole 111.

The connection pipe 140 may include first, second and third pipe sections 141, 142 and 143 from rear to front, and slopes of the first, second and third pipe sections 141, 142 and 143 gradually decrease. The design has the advantages that the air flow can smoothly flow from the air inlet 111 to the air outlet 112, which is beneficial to reducing the air outlet resistance of the air flow and realizing the long-distance air outlet of the air outlet 112.

In an alternative embodiment, the air conditioning indoor unit 10 may further include an adjustment assembly 400, the adjustment assembly 400 including at least an adjustment plate 410, the adjustment plate 410 being configured to be controllably moved having a first use position in which the air inlet aperture 111 is blocked and a second use position in which the air inlet aperture 111 is exposed.

With the above structure, when the air outlet 112 needs to be closed, the adjusting plate 410 can be moved to the second use position, so as to cover the air inlet 111, and the air flow generated by the cross-flow fan is blown out from the air outlet 120. When the air outlet 112 needs to be opened, the adjusting plate 410 can be moved to the first use position, so that the air inlet 111 is exposed, and part of the air flow generated by the cross-flow fan can be blown out through the air outlet 112. Thus, the opening or closing of the air outlet 112 can be flexibly controlled, so that the air outlet mode of the indoor unit 10 of the air conditioner is more diversified.

Referring to fig. 4 and 5, an adjusting plate 410 may be disposed in the air outlet duct 110, the adjusting plate 410 is elongated extending along a lateral direction of the casing 100, and a lower surface of the adjusting plate 410 is attached to an upper surface of a duct bottom wall of the air outlet duct 110. In this way, the bottom wall of the air duct can be used to support the adjusting plate 410, so that the adjusting plate 410 can be moved more safely and reliably.

It will be appreciated that the above embodiment is to indirectly close or open the air outlet 112 by shielding or exposing the air inlet 111 with the adjusting plate 410. In other examples, the adjusting plate 410 may be disposed at the air outlet 120, and the air outlet 112 may be directly closed or opened by shielding or exposing the air hole 112 by the adjusting plate 410, but this design may obstruct the normal air outlet of the air outlet duct 110, and the adjusting plate 410 may be exposed after the air deflector 210 is opened, so as to affect the aesthetic appearance of the indoor unit 10.

In one example, the adjusting plate 410 may be provided with a plurality of relief holes 411, where the relief holes 411 are staggered with the air inlet holes 111 one by one when the adjusting plate 410 is in the first use position, and the relief holes 411 are coincident with the air inlet holes 111 one by one when the adjusting plate 410 is in the second use position. In this way, the adjusting plate 410 may be disposed on top of the yielding hole 411, and by moving the adjusting plate 410 laterally, the yielding hole 411 on the adjusting plate 410 may be staggered or overlapped with the air inlet 111, which is beneficial to reducing the moving distance of the adjusting plate 410.

In other embodiments, the adjusting plate 410 may not have the plurality of relief holes 411, and the adjusting plate 410 may cover the air inlet 111 or expose the air inlet 111 by moving the adjusting plate 410 back and forth.

In an alternative embodiment, the adjusting assembly 400 further includes a stepper motor 420 and a connecting rod 430, wherein one end of the connecting rod 430 is fixedly connected with the stepper motor 420, the other end is rotatably connected with the adjusting plate 410, and the stepper motor 420 is configured to drive the adjusting plate 410 to move laterally through the connecting rod 430, so that the abdication hole 411 is staggered or overlapped with the air inlet 111. Therefore, the transverse reciprocating movement of the adjusting plate 410 can be controlled by controlling the forward and backward movement of the motor, so that the air inlet 111 can be opened or closed more conveniently.

In the embodiment of the present invention shown in the drawings, the stepping motor 420 is disposed in front of the left end of the adjustment plate 410, and controls the lateral movement of the adjustment plate 410 by driving the connection rod 430 to swing left and right. In this way, the occupation of the lateral space of the air conditioning indoor unit 10 can be saved, and the increase of the lateral distance of the air conditioning indoor unit 10 due to the arrangement of the stepping motor 420 can be avoided.

It will be appreciated that, in the above description, the stepper motor 420 is a rotating motor, in order to ensure the reliability and stability of the movement of the adjusting plate 410, a connecting rod 430 (not shown) may be disposed at the other end of the adjusting plate 410, one end of the connecting rod 430 is rotatably connected to the adjusting plate 410, and the other end is rotatably connected to the air duct bottom wall of the air outlet duct 110.

In another example, the stepper motor 420 may be a linear motor, for example, the stepper motor 420 is disposed at the left end of the adjusting plate 410, and the output shaft thereof extends along the lateral direction of the casing 100 and is directly connected to the left end of the adjusting plate 410, so as to drive the adjusting plate 410 to move laterally through the expansion and contraction of the output shaft.

Of course, the above examples are merely illustrative, and those skilled in the art should easily design a connection structure for the adjusting plate 410 of the present embodiment to enable smooth movement thereof, and these expansions should fall within the scope of the present invention.

In an alternative embodiment, the angle between the air outlet direction of the air outlet 112 and the horizontal plane may be-30 ° to 30 °, such as-30 °, -15 °, 0 °, 15 °, 30 °, etc., in order to ensure that the air flow blown out from the air outlet 112 can be effectively blown to the lee side of the air deflector 210.

In the embodiment shown in the drawings of the present invention, the included angle between the air outlet direction of the air outlet 112 and the horizontal plane is 10 °, that is, the air outlet 112 is horizontally and forwardly discharged, and the third pipe section 143 of the connection pipe 140 horizontally extends from the rear to the front, and has a slope of 0. The angle between the opened air deflector 210 and the horizontal plane is usually about 45 degrees, so that the air outlet 112 can directly blow the middle area of the air deflector 210, which is beneficial to keeping the temperature of the windward side and the leeward side of the air deflector 210 uniform. Since the air outlet holes 112 have a large air outlet velocity, the air flowing to the leeward side of the air guide plate 210 can flow along the leeward side of the air guide plate 210 in a long distance, thereby increasing the air supply distance and the air supply range.

In an alternative embodiment, the diameter of the air outlet holes 112 may be 5mm to 20mm, such as 5mm, 10mm, 15mm, 20mm, etc., and the distance between adjacent air outlet holes 112 may be 2cm to 20cm, such as 2cm, 5cm, 10cm, 15cm, 20cm, etc. Specifically, the diameters of the air outlet holes 112 and the distances between the adjacent air outlet holes 112 may be set in a targeted manner according to actual conditions.

In an alternative embodiment, a plurality of swing blades 220 are disposed on the inner side of the air outlet 120, and the plurality of swing blades 220 are arranged at intervals along the transverse direction of the casing 100, each swing blade 220 has a plurality of through holes passing through transversely, and each swing blade 220 can swing left and right around a vertical axis. Therefore, the swing blades 220 can be utilized to swing to break up the air flow in the air outlet air duct 110, so that the air flow blown out from the air outlet 120 is softer, and direct blowing to a human body is avoided.

Referring to fig. 6, it should be noted that the swing blade 220 is located on a side of the air inlet 111 near the air outlet 120, so as to prevent the swing blade 220 from swinging to block the air flow from entering the air inlet 111 normally.

According to any one of the optional embodiments or the combination of multiple optional embodiments, the following beneficial effects can be achieved according to the embodiment of the invention:

according to the indoor unit 10 of the air conditioner, the air outlet channel 110 is provided with the plurality of air outlet holes 112, and after the air guide plate 210 is opened, each air outlet hole 112 can be controlled to outlet air towards the leeward side of the air guide plate 210, so that the temperature difference between the leeward side and the windward side of the air guide plate 210 is reduced, the condensation problem of the air guide plate 210 is effectively prevented, the air pressure of the air outlet holes 112 is large, the air outlet holes have a longer air supply distance, the air supply range of the air conditioner is enlarged, the indoor temperature can be quickly adjusted, and the use experience of a user is improved.

Further, the indoor unit 10 of the present embodiment of the invention, the adjusting assembly 400 includes an adjusting plate 410, and the adjusting plate 410 can be controllably moved, and has a first use position for shielding the air inlet 111 and a second use position for exposing the air inlet 111. In this way, the opening or closing of the air outlet 112 can be flexibly controlled by moving the position of the adjusting plate 410, so that the air outlet mode of the indoor unit 10 of the air conditioner is more diversified.

Further, in the indoor unit 10 of the present embodiment, the connection pipe 140 includes the first, second and third pipe sections 141, 142 and 143 from the rear to the front, and the slopes of the first, second and third pipe sections 141, 142 and 143 are gradually decreased. After the cross-flow fan is started, the air flow can easily enter the air inlet 111, and smoothly flow out of the air outlet 112 after passing through the first pipe section 141, the second pipe section 142 and the third pipe section 143, which is beneficial to reducing the flow resistance of the air flow.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention.
