With reference to fig. 1, the air inlet and the air outlet of the embedded air conditioner are arranged at the lower side of the panel, the air inlet is arranged at the center, and the air outlet is arranged at the periphery of the panel. Without the air deflector 20, the air conditioner is discharged downward. In order to ensure that the air-conditioning wind is not directly blown, the wind deflector 20 is provided to adjust the wind outlet angle of the air-conditioning wind.

Referring to fig. 2-3, an embodiment of the present disclosure provides an embedded air conditioner, including an air outlet duct 10, wherein: the outer side wall 11 of the air outlet duct 10 comprises a bending section 111 and an extension section 112, wherein the bending section 111 gradually expands towards the air outlet outer end of the air outlet duct 10 and is connected with the extension section 112, and the extension section 112 gradually inwards concave towards the air outlet inner end of the air outlet duct 10 to form one or more concave parts.

The outer end of the air outlet duct 10 is close to one side of the air outlet duct 10; the air outlet inner end of the air outlet duct 10 is close to one side of the air inlet of the air outlet duct 10.

Alternatively, when the extension section 112 gradually concave inward toward the air outlet inner end of the air outlet duct 10 to form a plurality of concave portions, the curvature of the plurality of concave portions gradually increases from the air outlet outer end of the air outlet duct 10 toward the air outlet inner end of the air outlet duct 10. Thus, the conduction path of the air outlet conducted to the extension section 112 is prolonged, the action time of the extension section 112 on the air outlet is prolonged, the air outlet direction of the air outlet is changed for a plurality of times in different degrees, the air outlet can be effectively prevented from being directly sent out along the outer side wall 11 and blown onto the ceiling or the wall surface outside the panel, meanwhile, the air outlet can be prevented from directly blowing to a user, a windless air outlet is created for the user, and the user experience is improved.

The bending section 111 gradually expands towards the outer end of the air outlet duct 10 and is connected with the extension section 112, so that the air outlet of the air outlet duct is gradually dispersed along the bending section 111, one part of the air outlet is redirected to the air deflector 20, and the other part of the air outlet is transmitted to the extension section 112; the extension section 112 gradually concave inwards towards the air outlet inner end of the air outlet duct 10 to form a concave part, so that the air outlet direction of the air outlet conducted to the extension section 112 is further changed, and the embedded air conditioner is enabled to downwards along the air outlet direction of the outer side wall 11.

By adopting the embedded air conditioner provided by the embodiment of the disclosure, the outer side wall 11 of the embedded air conditioner is designed, the air outlet of the embedded air conditioner is sequentially commutated through the bending section 111 and the extension section 112, and a part of the air outlet is redirected to the direction of the air deflector 20, so that the air outlet can be prevented from being directly sent out along the outer side wall 11 and blown onto the ceiling or the wall surface outside the panel, the ceiling or the wall surface is exposed, and the ceiling is moldy or dirty after long-term use, and the indoor attractiveness is influenced.

Optionally, as shown in fig. 3, one or more protrusions 1121 are provided within the recess. The protrusion 1121 has a conical protrusion 1121. In this way, the concave portion of the extension section 112 gradually concave commutates the flowing air outlet along the extending direction of the extension section 112, and the protrusion 1121 commutates the flowing air outlet along the vertical direction of the extension section 112, so that the flow direction of the air outlet can be disturbed better, and the windless sense of the air outlet of the embedded air conditioner can be enhanced.

In some embodiments, as shown in fig. 3, the outer side wall 11 of the outlet wind tunnel 10 further includes a vertical section 113 connected to the curved section 111, the vertical section 113 including a telescoping portion configured to adjust the length of the vertical section 113.

In practical application, the telescopic part can be a threaded structure, and comprises an external threaded structure and an internal threaded structure matched with the external threaded structure. The vertical section 113 is provided with a first vertical section 113 and a second vertical section 113 which are connected with each other, an external thread structure is arranged at the end part of the first vertical section 113, an internal thread structure is arranged at the end part of the second vertical section 113, and the length of the vertical section 113 is adjusted through the mutual matching of the internal thread structure and the external thread structure.

In this alternative embodiment, the outer side wall 11 of the air outlet duct 10 is designed, and a vertical section 113 with adjustable length is added. When the length of the vertical section 113 is increased, the vertical section 113 guides more air out of the air outlet duct 10 to the air deflector 20 to flow out; when the length of the vertical section 113 is shortened, more air out of the air outlet duct 10 flows out along the outer side wall 11 of the air outlet duct 10. Thus, by changing the length of the vertical section 113, the effect of changing the air outlet distribution of the air outlet duct 10 can be achieved, and a person skilled in the art can adjust the length of the vertical section 113 by adjusting the telescopic part according to the actual air outlet requirement of the embedded air conditioner.

In some embodiments, as shown in fig. 3, the inner side wall 12 of the air outlet duct 10 is disposed opposite to the outer side wall 11, and the inner side wall 12 gradually expands toward the air outlet outer end of the air outlet duct 10. In this way, through the guiding function of the inner side wall 12 gradually expanding towards the outer end of the air outlet duct 10, the air outlet of the air outlet duct 10 can more flow out through the air deflector 20 and the outer side wall 11 of the air outlet duct 10, so that the air outlet direction is adjustable and controllable.

In some embodiments, as shown in connection with fig. 4, the embedded air conditioner further includes an air deflector 20 disposed at an air outlet of the air outlet duct 10, wherein: the wind deflector 20 comprises a wind guiding section 21 and a bending section 22, wherein the bending section 22 is connected with the end part of the wind guiding section 21.

Optionally, bending section 22 comprises a first bending section 221 and a second bending section 222, wherein: the first bending section 221 is configured as a plane plate gradually extending from the first end of the air guiding section 21 to the air outlet inner end of the air outlet duct 10; the second bending section 222 is configured as a curved plate that gradually extends from the second end of the air deflector 20 toward the air outlet outer end of the air outlet duct 10.

The first bending structure of the air deflector 20 can ensure that when the air deflector 20 is opened, the air on the back side of the air deflector 20 flows along the outer side of the air deflector 20 based on the adherence effect, so that on one hand, the air is prevented from directly entering the air inlet after being blown out from the back side of the air deflector 20, and the air loop is caused; on the other hand, the temperature difference at two sides of the air deflector 20 can be balanced, and the condensation phenomenon of the air deflector 20 caused by the temperature difference is reduced. The second bending structure of the air deflector 20 can ensure that the air outlet angle is raised when the air blows through the air deflector 20, so that the larger opening angle of the air deflector 20 can be ensured, the smaller air outlet angle can be realized, the larger opening angle can effectively reduce the air guide wind resistance, and the whole air outlet quantity is ensured.

Optionally, the first included angle between the first bending section 221 and the air guiding section 21 ranges from 20 ° to 30 ° (degrees), for example, 20 °, 25 °, 28 °, 30 °; the second included angle between the second bending section 222 and the air guiding section 21 ranges from 20 ° to 30 °, for example, 20 °, 25 °, 28 °, 30 °.

When the traditional embedded air conditioner operates, in a refrigeration state, the air outlet of the embedded air conditioner needs to prevent direct blowing, the included angle between the air flow direction and the horizontal plane needs to be controlled not to be too large, and the included angle between the air flow direction and the horizontal plane is ensured to be 5-20 degrees. The horizontal included angle of the air deflector is too small, the opening rate of the air duct is too small, and the air output of the air conditioner is directly affected. Along with the increase of the horizontal included angle of the air deflector, when the included angle reaches 35 degrees all the time, the air output of the air conditioner is gradually increased, and the normal use requirement is met. When the air deflector is arranged at a horizontal included angle of 10-35 degrees, the air current always blows against the ceiling, so that the ceiling is blown dirty after long-term use, and the indoor attractiveness is affected; when the horizontal included angle of the air deflector is 40-55 degrees, the air output of the air conditioner is stable, but the specified air flow angle cannot be achieved.

After the included angles among the first bending section 221, the second bending section 222 and the air guiding section 21 are respectively set to the above angles, the air supply performance of the embedded air conditioner is obviously improved. The optimization principle of the novel embedded air conditioner will be described below for two states of cooling and heating.

In the cold state:

the included angle between the first bending section 221 and the air guiding section 21 is set to be an angle within 20-30 degrees, the extended air guiding plate 20 increases the effective height between the highest point of the air guiding plate and the lowest point of the inner side wall 12 of the air outlet duct 10, and the air flow at the inner side wall 12 is enhanced. The air flow on the two sides of the air deflector 20 simultaneously acts to strengthen the stability of the air flow, meanwhile, as the upper side of the air deflector 20 is cold air, the lower side of the air deflector 20 is hot air, the air deflector 20 is a cold and hot air junction, condensation can not be easily formed due to heat insulation of the air deflector 20, after the air flow intensity of the inner side wall 12 is increased, the hot air on the rear side of the air deflector 20 is blown away, the temperature difference between the air on the upper side and the air lower side of the air deflector 20 is reduced, and the condensation phenomenon of the air deflector 20 is eliminated.

The included angle between the second bending section 222 and the air guiding section 21 is set to be an angle (for example, 30 degrees) within 20-30 degrees, when the air flow angle of the extended air guiding plate 20 is 10 degrees, the opening angle of the air guiding plate 20 is changed to be 40 degrees, the opening rate of the air guiding plate 20 is increased, the integral air outlet quantity of the embedded air conditioner under the refrigerating condition is increased, the sufficient refrigerating capacity is ensured, and meanwhile, the purpose that people are not directly blown by the refrigerating of the embedded air conditioner is achieved.

In the heating state:

the included angle between the first bending section 221 and the air guiding section 21 is set to be an angle within 20-30 degrees, the extended air guiding plate 20 increases the effective height between the highest point of the air guiding plate and the lowest point of the inner side wall 12 of the air outlet duct 10, and the air flow at the inner side wall 12 is enhanced. Through the combined action of the air quantity at two sides of the air deflector 20, the angle of the air flow is more stable, the air speed is larger, and the effect of hot air landing can be better achieved.

The included angle between the second bending section 222 and the air guiding section 21 is set to be an angle (for example, 30 degrees) within 20-30 degrees, and in order to achieve a heating air flow angle of 30 degrees, the opening angle of the air guiding plate 20 is changed to be 60 degrees, the opening amplitude of the air guiding plate 20 is larger, and the air outlet volume of the embedded air conditioner is improved greatly.

Taking 5-piece embedded air conditioner as an example, a direct air deflector (without the first bending section 221 and the second bending section 222) and a broken line air deflector (a first included angle between the first bending section 221 and the air guiding section 21 is 30 degrees, and a second included angle between the second bending section 222 and the air guiding section 21 is 30 degrees) were respectively installed in the center of a room with 8m x 8m, and the movement direction of the air flow of the embedded air conditioner was analyzed by adopting CFD simulation, and the results are shown in the following table 1:

TABLE 1

From table 1 above, it is clear that under the same air flow angle of the air deflector, the air output of the fold line air deflector is obviously improved relative to the air output of the straight air deflector, and under different angles, the air output of the fold line air deflector is averagely improved by 6% relative to the air output of the straight air deflector, so that the method has obvious progress.

Alternatively, the free end of the second bending section 222 is flush with the free end of the outer extension 112 when the opening angle of the air deflector 20 is maximized. When the opening angle of the air deflector 20 is maximum, the component of the air deflector 20 in the horizontal direction is minimum, and at this time, the free end of the second bending section 222 is flush with the free end of the extension section 112, so that the air guiding function of the air deflector 20 can be fully exerted, and the air outlet is prevented from directly blowing downwards after passing through the extension section 112.

In some embodiments, the free ends of the wind guiding segments 21 or the bending segments 22 are provided with notches 24. When the bending section 22 is a first bending section 221 (as shown in fig. 5) extending gradually from the first end of the air guiding section 21 to the air outlet inner end of the air outlet duct 10, the free end of the bending section 22 is provided with a notch 24; when the bending section 22 is a second bending section 222 gradually extending from the second end of the air deflector 20 to the air outlet outer end of the air outlet duct 10, the free end of the air guiding section 21 is provided with a notch 24. In this way, on the premise of realizing the air guiding function of the air guiding plate 20, the air guiding plate 20 can be prevented from interfering with other structures in the air outlet duct 10 when the air guiding plate 20 is opened, so that the normal operation of the air conditioner is affected.

In some embodiments, the embedded air conditioner further includes a motor shaft 25 configured to be coupled to the air deflector 20, and a distance between the motor shaft 25 and the inner sidewall 12 of the outlet duct 10 is greater than a distance between the motor shaft 25 and a free end edge of the bent end. Wherein, the motor shaft 25 is a connecting part between the motor and the air deflector 20, and the motor shaft 25 drives the air deflector 20 to rotate under the driving action of the motor. Because the panel of the embedded air conditioner is generally disposed along the inner side wall 12 of the air outlet duct 10, the distance between the motor shaft 25 and the inner side wall 12 of the air outlet duct 10 is greater than the distance between the motor shaft 25 and the free end edge of the bending end, so that the panel of the embedded air conditioner can be prevented from interfering when the air deflector 20 rotates.

In some embodiments, the free end of the epitaxial section 112 is provided with one or more first tail grooves. The air flow is blown out along the air outlet duct 10, the speed is increased continuously, the speed reaches the maximum at the air outlet, and noise is easy to be caused. Therefore, the first tail groove is designed at the free end of the extension section 112, so that the high-speed air flow at the extension section 112 is separated, and the air flow is diffused to the upper side and the lower side, so that the high-speed slender air flow is changed into the low-speed wide and thick air flow, and the noise reduction effect can be realized.

In some embodiments, as shown in connection with fig. 6-7, the free end of the second bending section 222 is provided with one or more tail grooves (second tail groove 2221). The main function of the second bending section 222 is to increase the opening angle of the air deflector 20 in the refrigeration state, and to increase the overall air output at a low angle while ensuring low-angle air output in the refrigeration state. However, through CFD (Computational Fluid Dynamics ) simulation analysis, the velocity of the air flow at the second bending section 222 is maximized, which is an important factor in the formation of aerodynamic noise. Therefore, the second tail groove 2221 is designed at the free end of the second bending section 222 to separate the high-speed air flow at the second bending section 222, diffuse the air flow to the upper side and the lower side, change the high-speed slender air flow into low-speed wide and thick air flow, increase the heat exchange area of the air flow, and reduce the high-speed aerodynamic noise.

In some embodiments, as shown in connection with fig. 8, one or more sub-air deflectors 26 are provided on the air guiding section 21, and the sub-air deflectors 26 are rotatable between a first position in which they are attached to the air guiding section 21 and a second position in which they are perpendicular to the air guiding section 21. Through CFD simulation analysis and experimental tests, the air flow of each air deflector 20 of the embedded air conditioner is strong in the middle and weak in the two sides, so that the air flow does not exist at the four corners of the air conditioner during embedding, and the heat exchange of the air flow is not sensed. In order to increase the heat exchange range of the embedded air conditioner, one or more sub air deflectors 26 are arranged on the air guide section 21, so that the air flow of the embedded air conditioner can be ensured to diffuse not only to the middle area of the air conditioner, but also to the corner areas of the air conditioner.

Alternatively, as shown in connection with fig. 10-11, the sub-air deflection 26 is provided with a microporous structure 23. The sub-air deflectors 26 diffuse the middle high-speed air flow to two sides, so that the pneumatic noise of the embedded air conditioner is increased, and in order to further optimize the type air deflector 20, the micro-pore structure 23 is arranged on the sub-air deflectors 26, and the micro-pore type sub-air deflectors 26 diffuse the high-speed air flow and simultaneously unload the high-speed air flow through the micro-pore structure 23, so that the speed concentration of the air flow is reduced, and the pneumatic noise of the air conditioner can be effectively reduced.

In some embodiments, as shown in connection with fig. 11-12, the second bending section 222 is provided with a microporous structure 23. The second bending section 222 increases the resistance to air flow when the air deflection 20 is fully opened during the heating process of the air conditioner. Thus, in order to reduce the resistance to wind guiding, a microporous structure 23 is provided on the second bending section 222.

In some embodiments, as shown in connection with fig. 9 and 11-12, a microporous structure 23 is provided on the air guiding section 21. In order to increase the comfort of the air deflector 20 in the cooling state, a microporous structure 23 is provided on the air guiding section 21. In this way, the air deflector 20 adopts the micropore structure 23 to discharge air in the fully closed state, so that the embedded air conditioner is ensured to radiate cold air downwards at the air speed of less than 1m/s, a user can obtain cold air without air feeling, and comfortable refrigeration can be achieved.

It will be understood that the "free end" in the embodiments of the present disclosure is the end of each component that is not connected to the other components.
