The term "upper" in the present embodiment generally refers to a direction away from the ground surface, for example, in the case where the air outlet device is installed on an indoor roof in a ceiling-mounted manner, the air guide structure 30 is configured to guide air upward, which means that air blown by the air guide structure 30 can be blown toward the roof.
The air outlet direction of the air outlet device does not point to the user, and the air sent out by the air outlet device cannot blow the user directly, so that the use experience of the user is improved. For example, when the air outlet device is arranged on an indoor unit of the air conditioner and the air conditioner is in a cooling mode, the air outlet device blows cold air upwards, the cold air naturally descends, and the effect of cooling without wind sensation can be achieved.
The air guiding structure 30 refers to a structure capable of guiding a wind direction, one end of the air guiding structure 30 is connected to the inside of the air outlet device, the other end of the air guiding structure 30 is connected to the outside of the air outlet device, and air can flow from the inside of the air outlet device to the outside through the air guiding structure 30.
As shown in fig. 3 and 4, optionally, the top wall 34 and the bottom wall 37 of the air outlet channel of the air guiding structure 30 are disposed to coincide with the projection of the two on the horizontal plane, for example, the portion C in fig. 3 and 4.
The top wall 34 of the air outlet channel refers to the inner wall of the air outlet channel at the side farther from the ground level, and the bottom wall 37 of the air outlet channel refers to the inner wall of the air outlet channel at the side closer to the ground level.
For example, when the air outlet channel is disposed obliquely, the projection of the edge of the top wall 36 of the air inlet end of the air outlet channel on the horizontal plane is located in the middle of the projection of the bottom wall 37 of the air outlet channel on the horizontal plane; or, the projection of the edge of the bottom wall 38 of the air outlet end of the air outlet channel on the horizontal plane is located in the middle of the projection of the top wall 34 of the air outlet channel on the horizontal plane.
The air outlet channel is communicated with the air outlet device, and the air outlet channel is communicated with the air outlet device.
When the air current inside the air outlet device flows into the air outlet channel, the air current firstly contacts the bottom wall 37 of the air outlet channel, under the guiding action of the bottom wall 37 of the air outlet channel, the air current contacts the top wall 34 of the air outlet channel, and under the guiding action of the top wall 34 and the bottom wall 37 of the air outlet channel, the air current is guided upwards. The top wall 34 and the bottom wall 37 of the air outlet channel of the air guide structure 30 are set to be partially overlapped by the projection of the top wall 36 edge of the air inlet end of the air outlet channel on the horizontal plane and are positioned in the middle of the projection of the bottom wall 37 of the air outlet channel on the horizontal plane, so that the top wall of the air inlet end of the air outlet channel has small obstruction effect on air flow, the air inlet smoothness of the air inlet end of the air outlet channel is increased, and the air outlet smoothness of the air outlet device is increased; or, the projection of the bottom wall 38 edge of the air outlet end of the air outlet channel on the horizontal plane is located in the middle of the top wall 34 of the air outlet channel in the projection of the horizontal plane, and then the air flow after the guiding action of the bottom wall 37 of the air outlet channel can be guided by the top wall 34 of the air outlet channel again, so that the air guide structure 30 has a better guiding action, in addition, under the guiding action of the top wall 35 of the air outlet end of the air outlet channel, the air blown out through the air outlet channel is blown upwards in a dispersed form, and the mixing process of the air flow sent out by the air outlet device and the indoor air is accelerated.

That is, the cross-sectional area of the outlet air passage is large, the outlet air flow rate is large, and the air in the target space can be adjusted in a short time. For example, in the case where the air outlet device is used in an air conditioning indoor unit, the air conditioning indoor unit can blow out a large amount of cold air/hot air in a short time, that is, can achieve an effect of adjusting the indoor temperature in a short time.
Optionally, the cross-sectional area of the bottom end 21 of the outlet casing is equal to or larger than the cross-sectional area of the top end.

In this air outlet device, the outlet 23 is provided in the radial direction of the axial flow fan 40, and the axial flow fan 40 has the air blowing direction in the axial direction, so that the air blown by the axial flow fan 40 is not directly blown out at the outlet 23, and the air with a high wind speed is prevented from being directly blown out from the outlet 23. The wind blown out by the axial fan 40 firstly blows towards the inner wall of the air outlet casing 20, so that the wind speed direction of the wind and the parameters of the air in the air outlet casing 20 are fully mixed in the air outlet casing 20, and the wind with lower speed and more uniform air parameters is blown out from the air outlet 23 under the action of the air pressure in the air outlet casing 20.
The air parameter is related to an application scene of the air outlet device, for example, when the air outlet device is used on an air conditioner indoor unit, the air parameter refers to air temperature; when the air outlet device is used in an oxygen generator, the air parameter refers to the oxygen content in the air; when the air outlet device is used on the air purifier, the air parameter indicates the content of pollutants in the air.
The air outlet 23 is disposed in the radial direction of the axial flow fan 40, and is distinguishable from the technical scheme that the air outlet 23 is disposed in the axial direction of the axial flow fan 40, so that the air outlet 23 disposed in the radial direction of the axial flow fan 40 includes: the air outlet 23 is directed in the radial direction of the axial flow fan 40, or the air outlet 23 side is directed in the radial direction of the axial flow fan 40. The axial flow fan 40 is circular, all radial positions of the axial flow fan 40 form a plane, and the condition that the air outlet 23 is intersected with the plane belongs to the condition that the air outlet 23 is directly opposite to the radial direction of the axial flow fan 40; the case where the outlet 23 does not intersect the plane is a case where the outlet 23 side is in the radial direction of the axial fan 40.
Alternatively, the diameter of the axial fan 40 is positively correlated with the cross-sectional area of the local outlet casing 20 at the radial direction of the axial fan 40. Under the condition that the cross-sectional area of the local air outlet shell 20 at the radial position of the axial flow fan 40 is large, the axial flow fan 40 with the large diameter is arranged, the distance between the axial flow fan 40 and the inner wall of the air outlet shell 20 is reduced, and the risk of air outlet and return air of an air inlet is reduced.
Alternatively, the outlet 23 may be opened to the outlet housing 20 so as to surround the axial flow fan 40. This embodiment can be implemented as: the air outlet 23 is disposed to surround along a circumference of the air outlet housing 20, and includes: the outlet 23 is provided around the entire circumference of the outlet housing 20, or the outlet 23 is provided around a partial region of the circumference of the outlet housing 20, for example, the outlet 23 is provided around 1/3 of the circumference of the outlet housing 20, or the outlet 23 is provided around 1/2 of the circumference of the outlet housing 20.
Under the condition that the air outlet 23 surrounds the air outlet casing 20 along a circle, the air outlet device can realize 360-degree air supply without dead angles.
Alternatively, the number of the axial flow fans 40 is two or more. Two or more than two axial fans 40 increase the mixing effect of the air outlet device on the air flow, and increase the total air outlet amount of the air outlet device. Correspondingly, the opening scheme of the air outlet 23 may adopt a scheme of increasing an air outlet surface, for example: air-out casing 20 comprises bottom skeleton 24 and air-out support 25, and bottom skeleton 24 and air-out support 25 are air outlet 23 around the breach that forms, and this air outlet 23 extends to the top 22 of air-out casing along air-out support 25 from the bottom skeleton 24 of air-out casing 20 bottom. The total air outlet amount of the axial flow fan 40 corresponds to the air outlet area of the air outlet 23, and the air outlet uniformity of the air outlet 23 is improved.
In the case that the number of the axial fans 40 is two or more, the radial positions of two or more axial fans 40 correspond to two or more positions of the outlet casing 20, and optionally, the air outlet 23 on the outlet casing 20 is arranged in the radial direction of one axial fan 40, and the axial fan 40 is one axial fan 40 on the leeward side of the two or more axial fans 40; optionally, the air outlet casing 20 is provided with two or more air outlets 23, and each air outlet 23 is disposed in a radial direction of one axial flow fan 40; optionally, the air outlet 23 of the air outlet housing 20 is disposed in a radial direction of the two or more axial fans 40, that is, the air outlet area of the air outlet 23 is large, and the air outlet 23 is located in the radial direction of the two or more axial fans 40 at the same time, for example, the air outlet housing 20 is composed of a bottom end frame 24 and an air outlet support 25, and a gap formed by the bottom end frame 24 and the air outlet support 25 in a surrounding manner is the air outlet 23; optionally, when the number of the axial fans 40 is three or more, two or more air outlets 23 are formed in the air outlet casing 20, and one or more air outlets 23 may be located in the radial direction of two or more axial fans 40 at the same time. It should be noted that, the "air outlet 23" mentioned in this paragraph is different from the "air outlet 23" in other contents in the embodiments of the present disclosure, and the air outlet 23 in this paragraph refers to the air outlet 23 with independent air outlet capability, including the air outlet 23 which is independently opened, and the plurality of small air outlets 23 which are formed by dividing one large air outlet 23 by the plurality of air guiding structures 30.
In the case where the number of the axial flow fans 40 is two or more, the diameter of each axial flow fan 40 is positively correlated with the cross-sectional area of the local outlet casing 20 in the radial direction of the axial flow fan 40. For example, if the cross-sectional area of the top end of the outlet casing 20 is smaller than or equal to the cross-sectional area of the bottom end of the outlet casing 20, that is, if there is a change in the cross-sectional area of the outlet casing 20, the diameters of two or more axial fans 40 are not completely the same. For example, the outlet casing 20 is conical, pyramid-shaped, circular truncated cone-shaped, or truncated pyramid-shaped, and the diameters of two or more axial fans 40 decrease progressively along the blowing direction of the axial fans 40.
As shown in fig. 16, the fan blades 41 of different axial fans 40 are alternatively distributed in a staggered manner. The axial projections of the fan blades 41 of the different axial fans 40 do not completely overlap. Along the blowing direction of the axial flow fan 40, after the fan blade 41 of one axial flow fan 40 accelerates the air, the air flows forward, and the fan blade 41 of the next axial flow fan 40 accelerates the air again, so that the multistage acceleration of the air is realized, and the air pressure inside the air outlet device is increased.
The blades 41 of the fans 40 with different axial flows are staggered with each other, and include: the blades 41 of adjacent axial fans 40 are distributed in a staggered manner, or the blades 41 of any two axial fans 40 are distributed in a staggered manner. In the case that there are many blades 41 of the axial flow fan 40, for example, in the case that 9 blades 41 are disposed on one axial flow fan 40, the distance between every two blades 41 on the axial flow fan 40 is small, and two or more axial flow fans 40 may be disposed such that the blades 41 of adjacent axial flow fans 40 are mutually staggered; in the case that one axial flow fan 40 is provided with 3 fan blades 41, the distance between every two fan blades 41 on the axial flow fan 40 is large, and two or more axial flow fans 40 may be arranged such that the fan blades 41 of any two axial flow fans 40 are distributed in a staggered manner.
Alternatively, two or more axial flow fans 40 are provided in series on one rotary shaft 42. Two or more axial fans 40 can be driven by one rotating shaft 42, which simplifies the complexity of manufacturing the air outlet device.
Alternatively, the distance between two adjacent axial fans 40 is equal to or greater than the height of either one of them. The distance between two adjacent axial fans 40 reduces the interference effect between the two fans.
Alternatively, the number of the fan blades 41 of the axial flow fan 40 is two or more. For example, the number of blades 41 of the axial flow fan 40 is 2, 3, 5, or 7.
Alternatively, as shown in fig. 6, 10 and 15, the partial outlet casing 20 at the blowing direction of the axial flow fan 40 is a convex structure 26. For example, the convex structure 26 may be a spherical structure. The axial fan 40 blows air to the convex structure 26, and the air blows to the air outlet 23 of the air outlet casing 20 under the guiding action of the convex structure 26. Through setting up this convex surface structure 26, improved the air-out effect of air-out device.

The bottom end 21 of the air outlet casing is a bottom end framework 24, and the heat exchanger 61 is arranged in the bottom end framework 24 in a shape-following manner, for example, when the air outlet casing 20 is conical, the bottom end framework 24 is circular, and the edge of the heat exchanger 61 is circular and is arranged in the circular bottom end framework 24; when the outlet casing 20 is in a pyramid shape, the bottom end frame 24 is polygonal, and the edge of the heat exchanger 61 is polygonal, and is disposed in the polygonal bottom end frame 24. In the process of entering the indoor unit, the air passes through the heat exchanger 61 and exchanges heat with the heat exchanger 61, and after entering the heat exchanger 61, the air flows out of the indoor unit from the air outlet 23 under the action of the fan, so that the effect of adjusting the temperature of the indoor air is realized.
