An air conditioner 1 according to an embodiment of the present invention is described below with reference to fig. 1 and 2.

As shown in fig. 1 and 2, an air conditioner 1 according to an embodiment of the present invention includes: the air duct 10 is a passage through which air enters and exits, the air duct 10 can enter the air duct 10, and then the air is discharged to the indoor space after heat exchange of the heat exchanger, so that the effects of refrigeration and heating are achieved. The oscillator 20 can realize self-oscillation air outlet, can improve indoor air mixing efficiency, can change an indoor stable airflow organization form, avoids airflow direct blowing, and achieves a natural and comfortable air supply effect.

As shown in fig. 1 and 2, a fan 11 is disposed in the air duct 10, the fan 11 can rotate, so that the air outside the air conditioner 1 can be sucked into the air duct 10, the air duct 10 is provided with an air duct outlet 12, the air after heat exchange can be discharged into a room through the air duct outlet 12, and in addition, the air duct outlet 12 is in a contracted shape, so that the air passing through the air duct outlet 12 can be processed by beam current.

As shown in fig. 1 and 2, the oscillator 20 includes: casing 21 and at least one baffle 22, casing 21 constitutes oscillator 20's holistic appearance structure, and can play sealed effect, prevent that the air current from appearing leaking when passing through oscillator 20, be formed with cavity 25 in the casing 21, the air current can enter into in the cavity 25, and at least one baffle 22 sets up in cavity 25, the air current is behind at least one baffle 22, can make the air current production deflection in the cavity 25, and can form the vortex in baffle 22 department, realize oscillator 20's self-oscillation air-out, so, can improve indoor air mixing efficiency, and can change indoor steady state air current tissue form, avoid the air current to blow directly, reach natural comfortable air supply effect.

As shown in fig. 1 and 2, the housing 21 includes: the air inlet 23 is communicated with the air duct outlet 12, the cavity 25 is communicated with the air inlet 23 and the air outlet 24, therefore, air flow can enter the cavity 25 through the air duct outlet 12 and the air inlet 23, then air can be discharged from the air outlet 24, and self-oscillating transient vortex air can be formed indoors after deflection.

As shown in fig. 1, after the at least one partition 22 is disposed in the cavity 25, the cavity 25 may be divided into a main flow channel 26 and at least one return flow channel 27, two ends of the main flow channel 26 are respectively disposed opposite to the air inlet 23 and the air outlet 24, an inlet 28 of the return flow channel 27 is defined between one end of the partition 22 adjacent to the air outlet 24 and the housing 21, and an outlet 29 of the return flow channel 27 is defined between one end of the partition 22 adjacent to the air inlet 23 and the housing 21. That is, when the air flow enters the main flow channel 26 through the air inlet 23, the air flow will flow toward the air outlet 24, and when the air flow flows to the air outlet 24, a part of the air flow enters the return flow channel 27 from the inlet 28 of the return flow channel 27 due to the blocking of the housing 21, and then returns to the main flow channel 26 from the outlet 29 of the return flow channel 27.

As shown in fig. 1, the partition 22 is provided with a first arc-shaped flow guiding section 30, and the first arc-shaped flow guiding section 30 is expanded in a direction toward the air outlet 24 so as to deflect a part of the air flow in the main flow passage 26 and then generate a scroll for another part of the air flow. That is, after the air flow in the return channel 27 returns to the main flow channel 26, a part of the air flow in the main flow channel 26 may be deflected, meanwhile, the first arc-shaped flow guiding section 30 may perform a flow guiding function, another part of the air flow may generate a reverse flow at the partition 22 along the direction of the air inlet 23, so as to generate a scroll effect, and the first arc-shaped flow guiding section 30 is configured to expand in a direction towards the air outlet 24, and the air flow may expand outward along the first arc-shaped flow guiding section 30, so as to generate a scroll effect high pressure region along the first arc-shaped flow guiding section 30.

The following is an example of the flow principle of the air flow when the partition plate 22 is two. Two partition plates 22 are arranged in the cavity 25 at intervals up and down.

Main air flow deflection effect: as shown in fig. 2, when the air flow reaches the vicinity of the air outlet 24 from the air inlet 23 along the central axis of the cavity 25, due to the structure of the housing 21 on the upper and lower sides of the air outlet 24, part of the air flow will flow along the structure surface of the housing 21 and enter the inlet 28 of the return channel 27, and due to the non-uniformity of the flow, the flow rate of the inlet 28 of the return channel 27 is different, for example: the flow rate of the air flow passing through the upper return duct 27 is greater than the flow rate of the air flow passing through the lower return duct 27, so that the flow rate at the outlet 29 of the return duct 27 is also different, and the main air flow entering from the air inlet 23 is deflected at the outlet 29 of the return duct 27 by the pushing action of the air flows of different flow rates at the upper and lower ends.

Deflection airflow swirl effect: as shown in fig. 2, after the deflected airflow approaches the lower partition 22, due to the "coanda" effect, part of the airflow will move along the lower partition 22, and the main airflow will move near the surface of the lower partition 22, and at the same time, the airflow in the return channel 27 will flow in the opposite direction at the upper partition 22 along the air inlet 23, creating a scroll effect, which will further push the main airflow to one side of the lower partition 22, and at the same time, create a downward deflection speed at the air outlet 24.

The main air flow is pushed to one side of the lower partition 22, the air flow rate of the inlet 28 of the return channel 27 at the side is larger than that of the inlet 28 of the return channel 27 at the upper end, so that the 'main air flow deflection effect' and the 'deflected air flow scroll effect' occur at the opposite side, and thus, upward and downward periodic flows are generated at the air outlet 24, so that the self-oscillation effect is generated.

From this, through being provided with oscillator 20, oscillator 20 can replace traditional horizontal aviation baffle structure, realizes the self-oscillation air-out from top to bottom in air outlet 24 department when no motion aviation baffle to can improve indoor mixed wind efficiency, can change indoor steady state air current tissue form moreover, avoid the air current to blow directly, reach natural comfortable air supply effect.

Further, as shown in fig. 1 and 2, the at least one partition 22 further includes: first wind guiding section 31 and second wind guiding section 32, first wind guiding section 31 extends to the direction of keeping away from air outlet 24, and first wind guiding section 31 sets up to the slope of mainstream passageway 26's direction, and second wind guiding section 32 extends to the direction of keeping away from air intake 23, and second wind guiding section 32 sets up to the slope of mainstream passageway 26's direction, defines the export 29 of return passage 27 between first wind guiding section 31 and casing 21, defines the import 28 of return passage 27 between second wind guiding section 32 and casing 21, first arc-shaped wind guiding section 30 connects between first wind guiding section 31 and second wind guiding section 32.

First wind guiding section 31 extends to the direction of keeping away from air outlet 24, and first wind guiding section 31 sets up to the direction slope of mainstream passageway 26, can guarantee like this that the air current deflects along first wind guiding section 31 after getting into cavity 25, second wind guiding section 32 extends to the direction of keeping away from air intake 23, and second wind guiding section 32 sets up to the direction slope of mainstream passageway 26, the air current can be led to air outlet 24 along second wind guiding section 32 more conveniently like this, thereby derive from air outlet 24. The first air guiding section 31 and the casing 21 define an outlet 29 of the return channel 27 therebetween, the second air guiding section 32 and the casing 21 define an inlet 28 of the return channel 27 therebetween, and part of the air flow can enter the return channel 27 from between the second air guiding section 32 and the casing 21 and then return to the main flow channel 26 from between the first air guiding section 31 and the casing 21. The first arc-shaped flow guide section 30 is connected between the first air guide section 31 and the second air guide section 32, and the first arc-shaped flow guide section 30 is not tangent to the first air guide section 31, that is, the air flow can expand outward along the first arc-shaped flow guide section 30 after moving along the first air guide section 31, so that the air flow generates a scroll effect high pressure area along the first arc-shaped flow guide section 30, and pushes the main air flow to the opposite side partition plate 22, so that the main air flow generates bending and turning.

As shown in fig. 1, in a longitudinal section of the oscillator 20, an included angle between the first air guiding section 31 and a central axis of the cavity 25 is α, an included angle between the second air guiding section 32 and the central axis of the cavity 25 is β, and a value range of α and β is: alpha is more than 0 degree and less than 90 degrees, beta is more than or equal to 0 degree and less than 90 degrees. The included angle range between the first air guiding section 31 and the central axis of the cavity 25 is as follows: alpha is more than 0 degree and less than 90 degrees, that is to say, first wind guiding section 31 needs to incline to the direction of mainstream passageway 26 and sets up, can guarantee like this that the air current deflects along first wind guiding section 31 after getting into cavity 25, and the contained angle scope of second wind guiding section 32 and cavity 25 axis is: beta is more than or equal to 0 degree and less than 90 degrees, the second air guide section 32 can be obliquely arranged towards the main flow channel 26 and can also be arranged in parallel with the central axis of the cavity 25, and thus, air flow can be guided to the air outlet 24 when passing through the second air guide section 32.

For example, as shown in fig. 1, there are two partitions 22, and the two partitions 22 are symmetrically disposed about a central axis of the cavity 25. When there are two partition boards 22, preferably, the two partition boards 22 are symmetrically disposed with respect to the central axis of the cavity 25, so that the amplitude difference between the upper and lower outlet air can be small after the airflow passes through the two partition boards 22 and is deflected, and of course, according to the actual structure and arrangement of the cavity 25, the two partition boards 22 may not be symmetrically disposed with respect to the central axis of the cavity 25.

According to an alternative embodiment of the present invention, as shown in fig. 1 and 2, the air duct member 10 includes: an upper air duct wall 13 and a lower air duct wall 14, the upper air duct wall 13 and the lower air duct wall 14 defining an air duct outlet 12, the cross-sectional area of each of the upper air duct wall 13 and the lower air duct wall 14 decreasing in a direction towards the air duct outlet 12. The upper air duct wall 13 and the lower air duct wall 14 define an air duct outlet 12, so that the air flow in the air duct member 10 can pass between the upper air duct wall 13 and the lower air duct wall 14 and can pass into the oscillator 20 through the air duct outlet 12, the cross-sectional areas of the upper air duct wall 13 and the lower air duct wall 14 are gradually reduced in the direction towards the air duct outlet 12, and thus the air flow can generate a jet effect after entering the cavity 25 through the air duct outlet 12 and the air inlet 23, so that the air flow can be prevented from diverging.

As shown in fig. 1 and fig. 2, one end of the upper air duct wall 13 away from the air duct outlet 12 is a first end 130, one end of the lower air duct wall 14 away from the air duct outlet 12 is a second end 140, an involute of the fan 11 is located at a front end of the second end 140, and a connection line between the first end 130 and the second end 140 is perpendicular to the upper air duct wall 13. The involute of the fan 11 is located at the front end of the second end 140, so that the influence of the fan 11 on the air flow between the upper air duct wall 13 and the lower air duct wall 14 can be reduced, and the connecting line of the first end 130 and the second end 140 is perpendicular to the upper air duct wall 13, that is, the second end 140 is the socket tongue arc tangent point of the air duct member 10, so that the arrangement is convenient, and the air flow can better enter between the upper air duct wall 13 and the lower air duct wall 14.

As shown in fig. 1 and 2, the end of the upper duct wall 13 connected to the oscillator 20 is a third end 131, the end of the lower duct wall 14 connected to the oscillator 20 is a fourth end 141, and in the longitudinal cross section of the duct member 10, the distance between the first end 130 and the second end 140 is a, the distance between the third end 131 and the fourth end 141 is b, and the relationship between a and b is: a is more than b. That is, the distance between the first end 130 and the second end 140 is greater than the distance between the third end 131 and the fourth end 141, so that the cross-sectional areas of the upper air duct wall 13 and the lower air duct wall 14 are gradually reduced in the direction toward the air duct outlet 12, so that the air flow enters the cavity 25 through the air duct outlet 12 and the air inlet 23 to generate a jet effect, and the air flow is prevented from diverging.

In addition, as shown in fig. 1 and fig. 2, an end of the first air guiding section 31 away from the air outlet 24 is a fifth end portion 33, an end of the first arc-shaped air guiding section 30 connected to the first air guiding section 31 is a sixth end portion 34, a distance between the fifth end portions 33 of the two partition plates 22 is c, and a distance between the sixth end portions 34 of the two partition plates 22 is d, and a relationship between b, c, and d is: d > c > b. The distance between the fifth ends 33 of the two partition plates 22 is greater than the distance between the third end 131 and the fourth end 141, so that the air flow entering the cavity 25 can be deflected toward the first air guiding section 31, thereby ensuring the deflection space after the air flow enters the main flow channel 26, and the distance between the sixth ends 34 of the two partition plates 22 is greater than the distance between the fifth ends 33 of the two partition plates 22, and as such, the deflection space of the air flow can be sufficiently large when the air flow flows along the main flow channel 26.

In addition, as shown in fig. 1 and 2, the housing 21 includes: the contraction section 35 is disposed at the air outlet 24, and the cross-sectional area of the contraction section 35 gradually decreases in a direction toward the air outlet 24. The cross-sectional area of the contracting section 35 is gradually decreased in the direction toward the air outlet 24, and the end of the contracting section 35 away from the air outlet 24 can be configured into an arc shape, so that the air flow can smoothly flow out along different angles during self-oscillation, and the resistance at the air outlet 24 is reduced.

Of course, as shown in fig. 1 and 2, the housing 21 further includes: and the second arc-shaped flow guide section 36 is connected to the contraction section 35, and the transverse sectional area of the second arc-shaped flow guide section 36 is gradually reduced in the direction towards the air outlet 24. By connecting the second curved flow guiding section 36 to the converging section 35, part of the air flow can flow along the surface of the second curved flow guiding section 36 and be guided to the inlet 28 of the return channel 27, thus entering the return channel 27. The cross-sectional area of the second arc-shaped flow guiding section 36 is gradually reduced in the direction toward the air outlet 24, so that a part of the air flow can be ensured to flow back to the inlet 28 of the corresponding return channel 27 when meeting the second arc-shaped flow guiding section 36. It should be noted that, on the premise of ensuring the flow guiding function of the second arc-shaped flow guiding section 36, the structure of the second arc-shaped flow guiding section 36 may not be arc-shaped.

Optionally, in a longitudinal section of the oscillator 20, a connecting line between two ends of a connection of the second arc-shaped flow guiding section 36 and the contraction section 35 is a first line section, and an extension line of the second air guiding section 32 and the first line section are in a non-intersecting relationship. That is, the extension line of the second wind guiding section 32 does not intersect with the connection line of the two ends of the connection between the second arc-shaped wind guiding section 36 and the contraction section 35, so that the influence of the second wind guiding section 32 on the wind outlet at the connection between the second arc-shaped wind guiding section 36 and the contraction section 35 can be avoided, and in addition, when the oscillator 20 is applied to the air conditioner 1, the setting needs to be performed in consideration of the space of the air duct of the air conditioner 1.

In addition, the oscillator 20 includes: and a dust-proof door movably disposed at the air outlet 24. The air outlet 24 can be provided with a dustproof door, and the dustproof door can rotate or slide at the air outlet 24, so that the air outlet 24 can be opened and closed, and dust in the air conditioner 1 in a shutdown state can enter the cavity 25 through the air outlet 24.
