Referring to fig. 1, the air inlet and the air outlet of the embedded air conditioner are located at the lower side of the panel, the air inlet is located at the center, and the air outlet is located at the periphery of the panel. Without the air deflector 20, the air conditioner blows air downward. In order to ensure that the air conditioning wind does not blow directly, the air deflector 20 is arranged to adjust the wind outlet angle of the air conditioning wind.

As shown in fig. 2 to 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 includes a curved section 111 and an extended section 112, wherein the curved section 111 gradually expands towards the outer end of the air outlet duct 10 and is connected with the extended section 112, and the extended section 112 gradually concaves inwards towards the inner end of the air outlet duct 10 to form one or more concave portions.

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

Optionally, when the extension segment 112 is gradually recessed towards the inner air outlet end of the air outlet duct 10 to form a plurality of concave portions, the curvature of the plurality of concave portions is gradually increased from the outer air outlet end of the air outlet duct 10 to the inner air outlet end of the air outlet duct 10. Like this, prolonged the conduction distance of conduction to the air-out of epitaxial section 112, increased epitaxial section 112 to the functioning time of this air-out to carry out the change of many times different degree to the air-out direction of this air-out, can prevent effectively that the air-out from directly seeing off along lateral wall 11, blow to on panel outside ceiling or the wall, simultaneously, also can avoid the air-out to directly blow the user, build a no wind and feel the air-out for the user, promoted user experience.

The curved section 111 gradually expands towards the outer end of the air outlet duct 10 and is connected with the extended section 112, so that the air outlet of the air outlet duct gradually disperses along the curved section 111, and 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 extended section 112; the extension section 112 is gradually concave inwards towards the inner end of the outlet air duct 10 to form a concave part, so that the outlet air direction of the outlet air conducted to the extension section 112 is further changed, and the outlet air of the embedded air conditioner is downward along 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 outlet air of the embedded air conditioner is sequentially reversed through the bending section 111 and the extending section 112, and a part of outlet air is redirected to the direction of the air deflector 20, so that the outlet air 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 prevented from being condensed, 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 disposed within the recess. The protrusion 1121 is configured as a conical protrusion 1121. Thus, the concave portion of the extension section 112 gradually concaved inwards reverses the flowing air outlet along the extension direction of the extension section 112, and the protrusion 1121 reverses the flowing air outlet along the vertical direction of the extension section 112, so that the flowing direction of the air outlet can be disturbed better, and the non-wind feeling of the air outlet of the embedded air conditioner is enhanced.

In some embodiments, as shown in fig. 3, the outer sidewall 11 of the wind outlet duct 10 further includes a vertical section 113 connected to the curved section 111, and the vertical section 113 includes a telescopic portion configured to adjust a length of the vertical section 113.

In practical application, the telescopic part can be a thread structure, including an external thread structure and an internal thread structure matched with the external thread 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, the end of the first vertical section 113 is provided with an external thread structure, the end of the second vertical section 113 is provided with an internal thread structure, 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 optional embodiment, the outer sidewall 11 of the air outlet duct 10 is designed, and the vertical section 113 with adjustable length is added. When the length of the vertical section 113 increases, the vertical section 113 guides more outlet air of the outlet air duct 10 to the air deflector 20 to flow out; when the length of the vertical section 113 is shortened, more outlet air of the outlet air duct 10 flows out along the outer sidewall 11 of the outlet air duct 10. Thus, the length of the vertical section 113 is changed to play a role in changing the distribution of the outlet air duct 10, 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 outlet air requirement of the embedded air conditioner.

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

In some embodiments, as shown in 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 air deflector 20 includes an air guiding section 21 and a bending section 22, wherein the bending section 22 is connected with an end of the air guiding section 21.

Optionally, the bending section 22 comprises a first bending section 221 and a second bending section 222, wherein: the first bending section 221 is a flat plate which gradually extends 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 a curved plate gradually extending from the second end of the air deflector 20 to the outer end of the outlet air duct 10.

The first bending structure of the air deflector 20 can ensure that when the air deflector 20 is opened, the wind on the back side of the air deflector 20 flows along the outer side of the air deflector 20 based on the wall-attached effect, so that on one hand, the wind is prevented from directly entering an air inlet after being directly blown out from the back side of the air deflector 20, and a wind loop is caused; on the other hand, the temperature difference between the 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 a larger opening angle of the air deflector 20 can be ensured, a smaller air outlet angle can be realized, the larger opening angle can effectively reduce the air guiding wind resistance, and the whole air output is ensured.

Optionally, a value range of the first included angle between the first bending section 221 and the air guiding section 21 is 20 ° to 30 ° (degrees), for example, 20 °, 25 °, 28 °, and 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 °, and 30 °.

When the traditional embedded air conditioner operates, in a refrigerating state, the air outlet of the embedded air conditioner needs to prevent direct blowing of people, 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. And the horizontal included angle of the air deflector is too small, and the opening rate of the air duct is too small, so that the air output of the air conditioner is directly influenced. Along with the increase of the horizontal included angle of the air deflector, when reaching 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 forms an included angle of 10-35 degrees horizontally, the air flow is always blown against the ceiling, and the ceiling is blown dirty after long-term use, so that the indoor appearance is influenced; when the horizontal included angle of the air deflector is 40-55 degrees, the air outlet quantity of the air conditioner is stable, but the air outlet quantity cannot reach the specified air flow angle.

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

In the refrigeration 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 of 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 current stability is strengthened in the both sides wind current simultaneous action of aviation baffle 20, simultaneously because the upside of aviation baffle 20 is cold air, the downside is hot-air, aviation baffle 20 is cold and hot air junction, and aviation baffle 20 can't form thermal-insulated very easy formation condensation, increases the wind current intensity of inside wall 12 department after, is favorable to blowing away the hot-air of aviation baffle 20 rear side, reduces the temperature difference of aviation baffle 20 upper and lower both sides air, is favorable to eliminating aviation baffle 20 condensation phenomenon.

The included angle between the second bending section 222 and the air guiding section 21 is set to be an angle within 20-30 degrees (taking 30 degrees as an example), 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 40 degrees, the opening rate of the air guiding plate 20 is increased, the integral air output of the embedded air conditioner under the refrigeration condition is increased, the sufficient refrigeration capacity is ensured, and the purpose that the embedded machine is refrigerated and does not blow people directly 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 of 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 quantities on the two sides of the air deflector 20, the angle of the air flow is more stable, the air speed is higher, and the effect of falling to the ground by hot air can be better achieved.

An included angle between the second bending section 222 and the air guiding section 21 is set to be an angle within 20-30 degrees (taking 30 degrees as an example), in order to achieve the heating air flow angle of 30 degrees, the opening angle of the air guiding plate 20 is changed to be 60 degrees after the air guiding plate 20 is extended, the opening range of the air guiding plate 20 is larger, and the air output of the embedded air conditioner is greatly improved.

Taking 5 octahedral embedded air conditioners as an example, the embedded air conditioners with a straight air deflector (without a first bending section 221 and a 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) are respectively installed in the center of a room of 8m × 8m, the moving direction of the airflow of the embedded air conditioners is analyzed by CFD simulation, and the results are shown in table 1 below:

TABLE 1

From the above table 1, it can be seen that, under the condition that the wind flow angles of the wind deflectors are the same, the air output of the broken line wind deflector is obviously improved relative to the air output of the straight wind deflector, and under different angles, the air output of the broken line wind deflector is averagely improved by 6% relative to the air output of the straight wind deflector, which is a significant progress.

Optionally, when the opening angle of the air deflector 20 is at a maximum, the free end of the second bend section 222 is flush with the free end of the extension section 112. When the opening angle of the air deflector 20 is the largest, the component of the air deflector 20 in the horizontal direction is the smallest, 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 is prevented from directly blowing downwards after passing through the extension section 112.

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

In some embodiments, the built-in air conditioner further includes a motor shaft 25 disposed to be connected to the air guide plate 20, and a distance between the motor shaft 25 and the inner sidewall 12 of the air outlet duct 10 is greater than a distance between the motor shaft 25 and a free end edge of the bent end. 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 usually disposed along the inner sidewall 12 of the air outlet duct 10, the distance between the motor shaft 25 and the inner sidewall 12 of the air outlet duct 10 is greater than the distance between the motor shaft 25 and the edge of the free end of the bent end, so that interference between the air deflector 20 and the panel of the embedded air conditioner can be avoided when the air deflector rotates.

In some embodiments, the free end of the extension segment 112 defines one or more first tail slots. The air flow is blown out along the air outlet duct 10, the speed is continuously increased, the speed reaches the maximum when the air outlet is used, and noise is easily caused. Therefore, the first tail groove is designed at the free end of the extension section 112, the high-speed airflow at the extension section 112 is separated, the airflow is diffused to the upper side and the lower side, the high-speed slender airflow is changed into the low-speed wide and thick airflow, and the noise reduction effect can be achieved.

In some embodiments, as shown in connection with fig. 6-7, the free end of the second bend segment 222 defines one or more tail grooves (second tail groove 2221). The second bending section 222 mainly functions to increase the opening angle of the air deflector 20 in the cooling state, so as to increase the overall air output at a low angle while ensuring the low-angle air output in the cooling state. However, the maximum velocity of the airflow at the second bend 222 is an important factor for the aerodynamic noise through the CFD (Computational Fluid Dynamics) simulation analysis. Therefore, the second tail slot 2221 is designed at the free end of the second bending section 222, so that the high-speed airflow at the second bending section 222 is divided, the airflow is diffused upwards and downwards, the high-speed slender airflow is changed into the low-speed wide and thick airflow, the heat exchange area of the airflow is increased, and the high-speed aerodynamic noise can be reduced.

In some embodiments, as shown in fig. 8, one or more sub-wind deflectors 26 are disposed on the wind guiding section 21, and the sub-wind deflectors 26 can rotate between a first position attached to the wind guiding section 21 and a second position perpendicular to the wind guiding section 21. CFD simulation analysis and experimental tests show that the air flow of each air deflector 20 of the embedded air conditioner is strong in the middle and weak on two sides, so that no air flow exists at four corners of the embedded air conditioner, and the air conditioner cannot feel air flow heat exchange. In order to increase the range of heat exchange 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 be diffused not only to the middle area of the air conditioner, but also to the corner areas of the air conditioner.

Optionally, as shown in fig. 10-11, the sub-air deflectors 26 are provided with micro-porous structures 23. In order to further optimize the type of the air deflector 20, the micropore structure 23 is arranged on the sub air deflector 26, and the micropore type sub air deflector 26 diffuses the high-speed air flow and unloads the high-speed air flow through the micropore 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 conjunction with fig. 11-12, the second bend section 222 is provided with a microporous structure 23. The second bent section 222 increases resistance to airflow when the air deflector 20 is fully opened during heating of the embedded air conditioner. Therefore, in order to reduce the resistance to wind, the microporous structure 23 is formed on the second bend 222.

In some embodiments, as shown in fig. 9 and fig. 11 to 12, the air guiding section 21 is provided with a micro-porous structure 23. 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. Thus, the air deflector 20 adopts the micropore structure 23 to exhaust air in the fully closed state, so that the embedded air conditioner is ensured to radiate cold air downwards at the wind speed of less than 1m/s, a user can obtain cold air without wind induction, and comfortable refrigeration can be achieved.

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