The embodiments of the present application will be described in detail below with reference to the accompanying drawings. Features in the embodiments described below may be combined with each other without conflict.

As shown in fig. 1 and 2, the present application discloses an air conditioning unit 10. The air conditioning unit 10 includes an outer frame 100 and a blower 200, and the blower 200 is provided inside the outer frame 100.

The air conditioning unit 10 includes an outer frame 100, and the outer frame 100 includes two first walls 110, a second wall 120, and top and bottom walls 130. The two first walls 110 are disposed opposite to each other along the first direction X, and each of the two first walls 110 is adjacent to the second wall 120. The top wall is disposed above the first wall 110 and the second wall 120, and the bottom wall 130 is disposed below the first wall 110 and the second wall 120. Of course, in other embodiments, the outer frame 100 may not be provided with the top wall and/or the bottom wall 130 separately, the number of the first wall 110 may be only one, and other structures of the air conditioning unit 10 may be used as the top wall, the bottom wall 130 and/or the first wall 110. The first wall 110, the second wall 120, the top wall and the bottom wall 130 enclose an accommodation space 140 configured to accommodate the blower 200. During use, the fan 200 may be placed in the accommodating space 140 to protect the fan 200.

It should be noted that, in order to make the accommodating space 140, the fan 200 located in the accommodating space 140, and the like more clearly visible, the top wall is not shown in the drawings.

The second wall 120 is provided with an air outlet 121. When the air conditioning unit 10 is in a use state, the fan 200 rotates to generate an air flow, and the air flow flows out of the outer frame 100 through the air outlet 121. In the process, during the process that the airflow generated by the fan 200 flows towards the second wall surface 120, at least part of the airflow flows towards the first wall surface 110 and the intersection position of the first wall surface 110 and the second wall surface 120.

In the present embodiment, the axis of the fan 200 coincides with the axis of the air outlet 121. Through the arrangement, the airflow generated by the fan 200 can smoothly flow to the air outlet 121, and the noise is avoided.

In one design, as shown in fig. 3, the first wall surface 1 and the second wall surface 2 are directly connected, and when the airflow generated by the fan 3 reaches the intersection position of the first wall surface 1 and the second wall surface 2, the airflow may generate a turbulent flow at the intersection position of the first wall surface 1 and the second wall surface 2 because the first wall surface 1 and the second wall surface 2 intersect to form a small included angle. The direction of flow of the gas generated by the rotation of the fan 3 is shown by the dotted arrows in the figure. Because the air flow generates turbulence in the outer frame, the air unit generates larger noise, thereby influencing the experience of users.

In this embodiment, as shown in fig. 1 and 2, the outer frame 100 further includes a baffle 150, two ends of the baffle 150 are respectively connected to the first wall 110 and the second wall 120, and the first wall 110 and the second wall 120 are smoothly connected by the baffle 150. In other words, one end of the air guiding plate 150 is smoothly connected to the first wall 110, that is, the included angle between the first wall 110 and the air guiding plate 150 is larger, and the other end of the air guiding plate 150 is smoothly connected to the second wall 120, that is, the included angle between the second wall 120 and the air guiding plate 150 is larger, so that the first wall 110 and the second wall 120 are smoothly connected.

It should be noted that in the present embodiment, the baffle 150 may have a plate-like structure. The baffle 150 is adhesively secured to the first wall 110 and the second wall 120. Of course, in other embodiments, the baffle 150 can be fixed to the first wall 110 and the second wall 120 by other methods, such as: riveting, welding, screwing or integral molding. Also, in other embodiments, the baffle 150 may take other shapes, such as: a columnar structure.

As shown in fig. 4, the flow guiding plate 150 can guide the airflow, and when the airflow generated by the fan 200 reaches the first wall 110 and the connection position between the first wall 110 and the second wall 120, the air can flow along the surface of the flow guiding plate 150 facing the accommodating space 140 to reach the second wall 120, and particularly smoothly reaches the air outlet 121 on the second wall 120, so that the airflow generated by the fan 200 can smoothly flow out of the outer frame 100 through the air outlet 121, and the turbulent flow phenomenon is avoided. The trajectory of the gas flow is shown in the direction of the dashed arrow in the figure. Through the arrangement, the baffle 150 connecting the first wall surface 110 and the second wall surface 120 is additionally arranged, so that the phenomenon of turbulent flow of the airflow at the position close to the air outlet 121 can be reduced, and the noise caused by the turbulent flow can be reduced.

In the present embodiment, the number of the air deflectors 150 corresponds to the number of the first wall surfaces 110, that is, the number of the air deflectors 150 is also two. Two ends of one of the flow guiding plates 150 are respectively connected with the second wall surface 120 and one of the first wall surfaces 110, and two ends of the other flow guiding plate 150 are respectively connected with the second wall surface 120 and the other first wall surface 110. The air outlet 121 is located between the two air deflectors 150. In the above arrangement, the flow guiding plate 150 is disposed at the position of the first wall 110 connecting the two first walls 110, so that the outer frame 100 reduces turbulence as much as possible and reduces noise of the air conditioning unit 10. Of course, in other embodiments, the number of the flow guiding plates 150 may also be one, and one flow guiding plate 150 is connected to the second wall surface 120 and any one of the first wall surfaces 110, so that the turbulence phenomenon can be reduced to some extent, and the noise can be reduced.

As shown in fig. 2, in one implementation, the baffle 150 intersects the second wall 120 to form a connecting end 160, and at least a portion of the connecting end 160 coincides with the boundary 122 of the outlet 121. Through the above arrangement, the gas flowing through the flow guide plate 150 can directly enter the air outlet 121, so that the gas can smoothly flow through the outlet outer frame 100. In the actual manufacturing process, it is difficult to achieve seamless connection between the baffle 150 and the second wall 120, and there is a certain step difference at the connection position between the baffle 150 and the second wall 120. Due to the existence of the step difference, the flow of the gas is disturbed to a certain degree, and problems such as turbulence, noise and the like occur. The connection end 160 coincides with the boundary 122 of the air outlet 121, so that the air flowing through the air guide plate 150 can directly enter the air outlet 121, and the influence of the step difference generated between the air guide plate 150 and the second wall surface 120 on the air flowing track is avoided. Meanwhile, in the process of flowing the air to the air outlet 121 along the flow guide plate 150, according to the pythagorean theorem, if the end of the flow guide plate 150 connected to the second wall 120 extends to the boundary 122 of the air outlet 121, the flow path of the air is shortest, and the flow speed of the air flowing out of the outer frame 100 through the air outlet 121 is faster, so as to avoid the problem of turbulent flow and loud noise caused by the accumulation of the air in the outer frame 100.

Of course, in other embodiments, as shown in fig. 5, the connecting end 160 may be spaced from the boundary 122 of the air outlet 121. The minimum distance from the connecting end 160 to the boundary 122 of the air outlet 121 is a first value d1, the length of the air outlet 121 is a second value d2, and the ratio of the first value d1 to the second value d2 is smaller than or equal to 1/2. With the above arrangement, the flow path of the gas can be also shortened, so that the gas can flow out of the outer frame 100 through the outlet port 121 at a high speed.

Further, as shown in fig. 1 and 2, the outer frame 100 includes a top end 101 and a bottom end 102 along the height direction H, and the baffle 150 extends from the top end 101 to the bottom end 102. Through the arrangement, the air flowing to the first wall surface 110 and the connection position of the first wall surface 110 and the second wall surface 120 can flow to the second wall surface 120 and/or the air outlet 121 along the flow guide plate 150, so that the phenomenon of turbulent flow of the air at the connection position of the first wall surface 110 and the second wall surface 120 is avoided, and the noise is reduced.

The height direction H is perpendicular to the first direction X.

As shown in fig. 6, in an embodiment, a surface 151 of the baffle 150 facing the accommodating space 140 is curved. As shown in fig. 7, in another embodiment, the outer frame 100 is provided with a receiving space 140 configured to receive the blower fan 200, and a surface 151 of the baffle 150 facing the receiving space 140 is flat, that is, a connecting line of any two points on the surface 151 of the baffle 150 facing the receiving space 140 falls on the surface 151. With the above arrangement, smooth connection between the first wall surface 110 and the second wall surface 120 is achieved, and at the same time, the gas can smoothly flow along the flow guide plate 150. Of course, in other embodiments, the surface 151 of the baffle 150 proximate the receiving space 140 may take on other shapes as well.

Further, as shown in fig. 1 and 2, the outer frame 100 further includes a first flow-guiding plate (not shown), the top wall is disposed above the first wall 110 and the second wall 120, two ends of the first flow-guiding plate are respectively connected to the second wall 120 and the top wall, the second wall 120 and the top wall are smoothly connected through the first flow-guiding plate, and the air outlet 121 is located below the first flow-guiding plate.

The outer frame 100 further comprises a second flow-guiding plate (not shown), the bottom wall 130 is disposed below the first wall 110 and the second wall 120, two ends of the second flow-guiding plate are respectively connected to the second wall 120 and the bottom wall 130, the second wall 120 and the bottom wall 130 are smoothly connected through the second flow-guiding plate, and the air outlet 121 is located above the second flow-guiding plate.

Through setting up first drainage plate and second drainage plate can make the gaseous flow to roof and diapire 130 that fan 200 produced can be along the smooth flow direction air outlet 121 of first drainage plate and second drainage plate, avoid gaseous piling up in outer frame 100, avoid appearing turbulent phenomenon, the production of noise abatement.

Further, the outer frame 100 further includes a noise reduction layer (not shown) disposed on a surface 151 of the baffle 150 facing the accommodating space 140. In this embodiment, the noise reduction layer is made of a flexible foam sponge product made of nitrile rubber and PVC, and has a thickness of 3 mm or more and 5 mm or less, so as to absorb noise generated by gas in the outer frame 100. Of course, in other embodiments, the noise reduction layer may not be separately disposed on the baffle 150, and the outer frame 100 may have a thickness of 15 mm to perform a certain noise reduction function.
