With the improvement of the living standard and quality of people, air conditioners have become indispensable electrical equipment for home offices. The air conditioner panel is generally provided with a temperature sensor for detecting the ambient temperature, and when the detected temperature reaches the preset temperature of the air conditioner, the air conditioner slows down the air outlet or stops the air outlet.

In the related art, because a preset gap is arranged between the upper edge of the air deflector in the air conditioner and the upper edge of the air duct outlet so as to ensure that the air deflector smoothly stretches out and withdraws, hot air emitted from the air duct outlet of the air conditioner can upwards along an air conditioner panel when the air deflector heats and sinks, and is sucked into the air conditioner from the gap between the upper edge of the air deflector and the upper edge of the air duct outlet, the air conditioner can cause the higher ambient temperature detected by a temperature sensor, and the air conditioner can be misjudged, so that the air conditioner can slow down or stop working.

The embodiment of the disclosure provides an air conditioner for preventing return air of an air conditioner, through limiting a first outlet line and an included angle between connecting lines, hot air cannot be sucked back into the air conditioner from a gap between the upper edge of an air deflector and the upper edge of an air duct outlet in the air outlet process, and further the air conditioner caused by misjudgment of a temperature sensor can be prevented from slowing down or stopping.

The embodiment of the disclosure provides an air conditioner for preventing return air of the air conditioner, as shown in fig. 1.

Referring to fig. 1, the air conditioner includes: an air conditioning panel 60 and an air deflector 50.

Optionally, the air conditioning panel 60 is provided with an air outlet, and an upper side of the air outlet includes an upper outlet molded line 61, where the upper outlet molded line includes a first outlet line 611, a connecting line 612, and a second outlet line 613 sequentially connected from outside to inside, and the first outlet line 611 intersects the connecting line 612 at a first connection point.

Among them, the air conditioner panel 60 is used to indirectly control an air conditioner operating mechanism to realize various functions of an air conditioner.

Optionally, an air deflector 50 is disposed at the air outlet, and the air deflector 50 includes an upper edge and a lower edge.

The air deflector 50 is an important part of the air conditioner, and can play a guiding role of different distances and different angles for the air discharged by the air conditioner, thereby improving the operation efficiency of the air conditioner.

Optionally, when the air deflector 50 is opened downward, a first distance a is provided between the upper edge and the first connection point, and an included angle C between the first outlet line 611 and the connection line 612 is greater than or equal to a first preset angle.

By limiting the included angle C between the first outlet line 611 and the connecting line 612, in the air outlet process, hot air cannot be sucked back into the air conditioner from the gap between the upper edge of the air deflector 50 and the upper edge of the air duct outlet, so that the air conditioner can be prevented from slowing down or stopping due to misjudgment of the temperature sensor.

Alternatively, the first preset angle is greater than or equal to 50.4 °, for example, the first preset angle may be 60 °, 70 °, 80 °, 90 °, or the like.

According to simulation calculation, when the first preset angle is larger than or equal to 50.4 degrees, air-conditioner air leakage cannot be sucked back into the air conditioner from a gap between the upper edge of the air deflector 50 and the upper edge of the air duct outlet, and when the first preset angle is smaller than 50.3 degrees, air-conditioner air leakage is sucked back into the air conditioner from a gap between the upper edge of the air deflector 50 and the upper edge of the air duct outlet, so that the detection result of the temperature sensor is affected.

In one possible embodiment, not shown in the figures, the first outlet line 611 is arc-shaped and the connecting line 612 is straight.

Wherein, the included angle between the tangent line of the first outlet line 611 and the connecting line 612 is greater than or equal to the first preset angle.

It is understood that the tangent of the first outlet line 612 is the tangent of the first outlet line 611 at the first connection point.

Optionally, the first outlet line 611 is concavely curved.

In another possible embodiment, not shown in the figure, the connection line 612 is arc-shaped and the first outlet line 611 is straight.

Wherein, the included angle C between the first outlet line 611 and the tangent line of the connecting line 612 is greater than or equal to the first preset angle.

It is understood that the tangent line of the connecting line 612 is the tangent line of the connecting line 612 at the first connecting point.

Optionally, the connecting line 612 is concavely curved.

In yet another possible embodiment, referring to fig. 1, the connection line 612 is linear and the first outlet line 611 is linear.

Wherein, the included angle C between the first outlet line 611 and the connecting line 612 is greater than or equal to the first preset angle.

Alternatively, when the air deflector 50 is opened downward, an extension line of the second outlet line 612 intersects the air deflector 50 at a second connection point.

The second connecting point is located at a second distance D from the first connecting point, and the second distance D is greater than or equal to the first distance a.

When the thickness B of the air deflector 50 and the first distance a remain unchanged, a second distance D is provided between the second connection point and the first connection point, and the second distance D is greater than or equal to the first distance a, so that the problem of back-sucking hot air of the air conditioner can be fundamentally avoided.

Fig. 4 and fig. 5 are a flow field diagram of an air conditioning indoor unit with an upper outlet line angle not defined according to an embodiment of the present disclosure and a flow field diagram of an air conditioning indoor unit with an upper outlet line angle defined according to an embodiment of the present disclosure, respectively.

As can be seen from fig. 4 and 5, in the air conditioning heating mode, when the angle of the upper outlet molded line 61 is not defined, the air flows vertically upward from the gap between the upper edge of the air deflector 50 and the upper edge of the air duct outlet, and then the hot air falls back into the air conditioner again from the gap between the upper edge of the air deflector 50 and the upper edge of the air duct outlet, causing erroneous judgment of the temperature sensor.

Conversely, when the angle between the connecting line 612 defining the upper outlet line 61 and the first outlet line 611 is greater than the preset angle, the air flows obliquely upward from the gap between the upper edge of the air deflector 50 and the upper edge of the air duct outlet, and then the hot air falls back to the outside of the air conditioner, so that erroneous judgment of the temperature sensor can be avoided.

The air deflector 50 provided in the embodiment of the present disclosure includes an outer air deflector 51 and an inner air deflector 52. Referring to fig. 2 to 3, the outer air guide plate 51 includes a first end mounting section 501, a second end mounting section 502, and an air guide section 503 disposed between the first end mounting section 501 and the second end mounting section 502. The outer air deflector 51 includes an upper edge 512 that abuts against an upper frame of an air outlet of the air conditioning indoor unit, and a lower edge 511 that abuts against a lower frame of the air outlet. The inner air deflector 52 is disposed on an inner side surface of the air guiding section 503, and the inner air deflector 52 includes a first arc 521 having a concave air guiding surface and a second arc 522 having a convex air guiding surface. The first curved plate 521 extends from the lower edge 511 of the outer air deflector 51 toward the upper edge 512, the second curved plate 522 extends from the upper edge 512 of the outer air deflector 51 toward the lower edge 511, and the second curved plate 522 is connected to the first curved plate 512.

The upper edge 512 of the outer air deflector 51 is abutted against the upper frame of the air outlet of the indoor unit of the air conditioner, and it is understood that the upper edge 512 of the outer air deflector 51 is abutted against the inner side wall of the upper frame, and it is also understood that the upper edge 512 of the outer air deflector 51 is abutted against the frame body portion of the upper frame. Similarly, the lower edge 511 of the outer air deflector 51 abuts against the lower frame of the air outlet of the indoor unit of the air conditioner, which means that the lower edge 511 of the outer air deflector 51 abuts against the inner side wall of the lower frame, and also means that the lower edge 511 of the outer air deflector 51 abuts against the frame portion of the lower frame. Of course, it is also understood that the upper edge 512 of the outer air deflector 51 is substantially abutted against the upper frame, and the lower edge 511 of the outer air deflector 51 is substantially abutted against the lower frame, so that the air deflector 50 may seal the air outlet of the indoor unit of the air conditioner.

As shown in fig. 2 and 3, the first curved plate 521 of the inner air deflector 52 is connected to the lower edge 511 of the outer air deflector 51, and the first curved plate 521 extends from the lower edge 511 of the outer air deflector 51 toward the upper edge 512, so that the first curved plate 521 forms an inner concave air guiding surface. Alternatively, the distance between the first curved plate 521 and the inner side surface of the outer air deflector 51 increases gradually from the lower edge 511 of the outer air deflector 51 toward the upper edge 512.

The inner deflector 52 also includes a second arcuate plate 522 having a convex air deflection surface. The second arcuate plate 522 is connected to the upper edge 512 of the outer air deflector 51 and extends from the upper edge 512 of the outer air deflector 51 toward the lower edge 511. Meanwhile, the inner air deflector 52 with the convex air deflector surface and the concave air deflector surface enables the outer air deflector 51 and the inner air deflector 52 to form a structure similar to a dolphin type air deflector 50, improves the guiding effect on air outlet at the air outlet, reduces air quantity loss of the air deflector 50 in the air guiding process, and improves the air outlet speed at the air outlet. Optionally, the curvature of the first curved plate 521 is smaller than the curvature of the second curved plate 522. The second curved plate 522 having the convex air guiding surface is curved more than the first curved plate 521 having the concave air guiding surface.

Alternatively, the ratio of the length of the inner air deflector 52 to the length of the outer air deflector 51 is greater than or equal to 2/3 and less than 1. In this way, a first end mounting section 501 for providing the first mount 551 and a second end mounting section 502 for providing the second mount 552 may be reserved. And the length of the inner air deflector 52 can be longer, the air guiding effect of the air deflector is improved, and the air quantity loss in the air guiding process is reduced. It will be appreciated that the length of the outer deflector 51 is the distance from the first wind deflector flap to the second wind deflector flap.

Optionally, the air deflector further includes a first mount 551 and a second mount 552. The first mount pad 551 sets up in the medial surface of first end installation section 501, and first mount pad 551 is used for the installation to drive the first actuating mechanism of aviation baffle switching-over pivoted, and the second mount pad 552 sets up in the medial surface of second end installation section 502, and second mount pad 552 is used for the installation to drive the second actuating mechanism of aviation baffle switching-over pivoted. Optionally, the first driving mechanism and the second driving mechanism have the same structure, and the driving mechanisms comprise structures such as a rocker, a driving sliding block, a driven sliding block, a track plate and the like, as follows.

The embodiment of the disclosure also provides a driving mechanism of the air deflector of the air conditioner, as shown in fig. 6 to 16.

Fig. 7 and 9 show the position of the first drive shaft of the rocker in the chute when the air deflector closes the air outlet, which can also be referred to as the centered position of the first drive shaft of the rocker.

In some embodiments, the driving mechanism for the air deflector 50 includes a rocker 10, a driving slider 20, a driven slider 30 and a track plate 40, the rocker 10 being provided with a first transmission shaft 121; the driving sliding block 20 is provided with a sliding groove 21, one end of the driving sliding block 20 is rotationally connected with the air deflector 50, and the first transmission shaft 121 is arranged in the sliding groove 21 in a sliding way; one end of the driven sliding block 30 is rotationally connected with the air deflector 50; a track plate 40 provided with a track portion for defining a movement locus of the driving slider 20 and the driven slider 30; the rocker 10 drives the driving slider 20 and the driven slider 30 to move under the limitation of the track portion through the sliding of the first transmission shaft 121 in the chute 21, so that the air deflector 50 extends out of the air outlet to a first preset position and then rotates.

The following embodiments describe structures such as a rocker, a driving slider, a driven slider, a track plate and the like in a driving mechanism of an air conditioner air deflector, and a rotating process of the driving mechanism driving the air deflector.

Alternatively, the driving force for the movement of the driving slider 20 comes from the rocker 10. The sliding of the rocker 10 in the chute 21 through the first transmission shaft 121 provides a driving force for the movement of the driving slider 20. One end of the driving slide block 20 and one end of the driven slide block 30 are connected with the air deflector 50, and driving force is transmitted to the driven slide block 30 through the connecting point of the air deflector 50 and the driven slide block 30, so that the driven slide block 30 is driven to move. The driving slide block 20 and the driven slide block 30 drive the air deflector 50 to extend out of the air outlet to a first preset position under the limitation of the track plate 40, and then drive the air deflector 50 to rotate. Thus, the slider assembly can be driven to move by the rocker 10, and the air deflector 50 is driven to extend out of the air outlet and then rotate to guide air. The driving mechanism has compact matching relation and simple structure. Meanwhile, the air deflector 50 extends out of the air conditioner to deflect air at a large angle, and the air supply range of the air conditioner is enlarged.

Alternatively, both the driving slider 20 and the driven slider 30 are rotatably connected to the wind deflector 50. Optionally, a first connection hole 27 is provided at one end of the driving slider 20, and a second connection hole 34 is provided at one end of the driven slider 30.

Optionally, the active slider 20 is further provided with at least two sliding posts moving along the track portion, including a first sliding post 25 at the top end and a second sliding post 26 in the middle.

Optionally, a second plate surface of the driven slider 30 opposite to the first plate surface thereof is provided with three sliding columns, which are arranged in a triangle shape, as shown in fig. 12, and are a third sliding column 31, a fourth sliding column 32 and a fifth sliding column 33. In this way, the limit effect of the track plate 40 on the movement track of the driven slider 30 is improved.

Optionally, the driven slider 30 is provided with a through slideway 35 penetrating through the plate surface thereof, the plate surface of the driving slider 20 opposite to the driven slider 30 is provided with a sliding column, and the sliding column moves along the track portion through the through slideway 35.

Optionally, the track portion includes a first track and a second track, the first track being herringbone, the first track being configured to define the active slider 20 for movement redirection; the second rail is linear and is arranged at the lower side of the first rail along the extending direction of the air deflector 50, and the second rail is used for limiting the driven sliding block 30 to perform linear motion; under the constraint of the first track and the second track, the driving slider 20 and the driven slider 30 move in a synchronous linear manner to drive the air deflector 50 to move to the first preset position, and then the driving slider 20 moves to generate relative movement with the driven slider 30, so as to drive the air deflector 50 to rotate.

In the embodiment of the disclosure, the first preset position is a position where the air deflector 50 horizontally extends out of the air conditioner and is about to start rotating, as shown in fig. 14, at this time, a certain distance is provided between the air deflector 50 and the air outlet, and the air deflector 50 can be opened upwards or downwards at the first preset position. In the embodiment of the present disclosure, the rotational position of the air deflector 50 is not limited to the first preset position, which is the initial position of the air deflector 50 rotating, and the rotation of the air deflector 50 can be understood as rotating while extending.

Optionally, the first track includes a first straight track 41, a first branch track 42, and a second branch track 43; the first branch rail 42 communicates with the first straight rail 41, the second branch rail 43 communicates with the first straight rail 41, and the extending directions of the first branch rail 42 and the second branch rail 43 are different.

In the disclosed embodiment, the first sliding post 25 of the active slider 20 moves in a first track and the second sliding post 26 of the active slider 20 moves in a second track. When the first sliding column 25 moves from the first straight track 41 to the first branch track 42 or the second branch track 43, the driving sliding block 20 and the driven sliding block 30 move relatively, and the movement of the driving sliding block 20 is redirected.

Alternatively, the second rail includes three linear rails, namely, a second linear rail 44, a third linear rail 45, and a fourth linear rail 46, along which the driven slider 30 is linearly moved all the time during the extension and rotation of the wind deflector 50. Wherein the third sliding column 31 moves in the second linear rail 44, the fourth sliding column 32 moves in the third linear rail 45, and the fifth sliding column 33 moves in the fourth linear rail 46. That is, the driven slider 30 moves linearly under the constraint of three rails.

It will be appreciated that the direction of the first linear rail 41 and the direction of the second rail are the same as the direction in which the deflector 50 protrudes from the closed condition to the first preset position.

Alternatively, the sliding groove 21 is linear, and the first transmission shaft 121 slides in the sliding groove 21 to drive the driving slider 20 to move. It will be appreciated that the direction of the chute 21 may be perpendicular to the direction in which the air deflector 50 extends from the closed state to the first preset position, or may have a preset included angle, and the direction of the chute 21 is not specifically limited in this application.

The manner in which the driving mechanism for the air deflector 50 drives the air deflector 50 to move is as follows:

the initial state of the moving assembly of the deflector 50 in the closed state is shown in fig. 7. When the rocker 10 rotates in the first direction or the second direction from the initial position shown in fig. 7, the first transmission shaft 121 slides in the sliding groove 21 of the driving slider 20 to drive the driving slider 20 and the driven slider 30 to move. The driving slider 20 moves linearly along the linear section of the first linear track 41, and the driven slider 30 moves linearly along the second track, so as to drive the air deflector 50 to move linearly to the first preset position. The first preset position may be understood as a position of the wind deflector 50 corresponding to when the first sliding column 25 of the driving slider 20 moves to the end of the straight line segment. In the embodiment of the disclosure, the first direction is clockwise, and the second direction is counterclockwise.

When the rocker 10 rotates in the first direction and the air deflector 50 reaches the first preset position, the second transmission shaft 122 of the rocker 10 moves to the first limit point, and the second transmission shaft 122 and the first limit point have an abutting force, so that a driving force for selecting a track is provided for the first sliding column 25 of the driving slider 20, so that the first sliding column 25 of the driving slider 20 enters the first branch track 42 from the first linear track 41, the second sliding column 26 of the driving slider 20 continues to move in the second linear track 44 through the penetrating slide way 35 of the driven slider 30, and the movement of the driving slider 20 is redirected. At the same time, the driven slider 30 continues to move linearly along the second track, so that the air deflector 50 is opened upward under the combined drive of the driving slider 20 and the driven slider 30, as shown in fig. 15.

When the rocker 10 rotates along the second direction, and the air deflector 50 reaches the first preset position, the second transmission shaft 122 of the rocker 10 moves to the second limit point, and as an abutment force exists between the second transmission shaft 122 and the second limit point, a driving force for selecting a track is further provided for the first sliding column 25 of the driving slider 20, so that the first sliding column 25 of the driving slider 20 enters the second branch track 43 from the first linear track 41, the second sliding column 26 of the driving slider 20 continues to move in the second linear track 44 through the penetrating slide way 35 of the driven slider 30, and the movement of the driving slider 20 is redirected. At the same time, the driven slider 30 continues to move linearly along the second track, so that the air deflector 50 is opened downward under the combined drive of the driving slider 20 and the driven slider 30, as shown in fig. 16.

It will be appreciated that fig. 5 and 14-16 are for illustrating the movement of the driving mechanism in different opening states of the air deflector, wherein the arc-shaped wind shielding flange of the air deflector is not shown.
