The air-out face frame 3 comprises a frame top 331 positioned at the top, two guide faces are formed on the upper surface of the frame top 331, the two guide faces are a first guide face 3312 and a second guide face 3313 respectively, the first guide face 3312 is connected to the front side of the second guide face 3313, the first guide face 3312 extends downwards obliquely in the rear-to-front direction, and the second guide face 3313 extends downwards obliquely in the front-to-rear direction.

For example, the foreign matters falling on the front side of the frame top 331 may slide down along the first guide surface 3312 toward the front side of the frame top 331, the foreign matters falling on the rear side of the frame top 331 may slide down along the second guide surface 3313 toward the rear side of the frame top 331, and the possibility that the foreign matters accumulate on the frame top 331 and block the air outlet of the frame top 331 may be reduced.
For example, in rainy and snowy weather, by the first guide surface 3312 extending obliquely downward in the back-to-front direction and the second guide surface 3313 extending obliquely downward in the front-to-back direction, it is possible to disperse rainy and snowy relatively quickly to the front side and the rear side of the frame top 331, the rainy and snowy near the front side of the frame top 331 can slide down along the first guide surface 3312 to the front side of the frame top 331, the rainy and snowy near the rear side of the frame top 331 can slide down along the second guide surface 3313 to the rear side of the frame top 331, and can be discharged from both the front side and the rear side of the frame top 331 at the same time, and the possibility of accumulation of rainy and snowy on the frame top 331 to shield the air outlet of the frame top 331 can be reduced as compared to a single side of the front side or the rear side of the frame top 331.
According to the heat pump outdoor unit 100 of the embodiment of the invention, the air outlet face frame 3 is arranged on the front side of the casing body 1, the casing body 1 and the front partition plate 2 jointly define the installation cavity, the air outlet face frame 3 and the front partition plate 2 jointly define the air outlet cavity 31, the air outlet cavity 31 is positioned on the front side of the casing body 1, the air outlet cavity 31 and the installation cavity are separated by the front partition plate 2, the heat exchange exhaust assembly is arranged in the installation cavity, when the heat pump outdoor unit 100 works, air flow discharged by the heat exchange exhaust assembly in the installation cavity is not directly discharged to the outside, but is discharged into the air outlet cavity 31 through the air flow outlet 21, the flow speed and impact force of the air outlet flow can be reduced through the buffer effect of the air outlet cavity 31, and the air outlet flow buffered by the air outlet cavity 31 is discharged to the outside through the air outlet, so that discomfort caused by the impact of the air outlet flow to a human body can be reduced. In addition, by the first guide surface 3312 of the frame top 331 extending obliquely downward in the back-to-front direction and the second guide surface 3313 extending obliquely downward in the front-to-back direction, the two guide surfaces can more effectively and uniformly guide the foreign matters outside the frame top 331 to move toward the front side or the back side of the frame top 331 under the action of self gravity, thereby reducing the possibility of the foreign matters accumulating in the frame top 331.
Referring to fig. 5-9, according to some embodiments of the invention, the included angle α1 between the first guide surface 3312 and the horizontal plane ranges from 15 ° to 25 °. For example, the included angle α1 between the first guide surface 3312 and the horizontal plane may be 15 °, 17 °,20 °, 22 °, 25 °, or the like. By making the included angle alpha 1 between the first diversion surface 3312 and the horizontal plane not smaller than 15 degrees, the first diversion surface 3312 can effectively conduct the external sundries on the frame top 331 so as to reduce or avoid the possibility that the external sundries accumulate on the frame top 331 and shade the air outlet of the frame top 331, and by making the included angle alpha 1 between the first diversion surface 3312 and the horizontal plane not larger than 25 degrees, the air flow can smoothly flow out from the air outlet of the frame top 331, and the flow resistance of the air flow flowing out from the air outlet of the frame top 331 is reduced.
For example, if the included angle α1 between the first diversion surface 3312 and the horizontal plane is too large, the included angle between the air outlet of the top 331 of the frame and the horizontal plane may be too large, which may cause the flow cross section of the air flow to be suddenly changed and increase the flow resistance of the air flow, and by making the included angle α1 between the first diversion surface 3312 and the horizontal plane not larger than 25 °, the air flow may more smoothly flow out from the air outlet of the top 331 of the frame. The included angle α1 between the first guide surface 3312 and the horizontal plane ranges from 15 degrees to 25 degrees, so that the guide effect of the guide surface 3312 on the external sundries at the top 331 of the frame and the smoothness of the airflow can be better achieved.
Referring to fig. 5-9, according to some embodiments of the invention, the included angle α2 between the second guide surface 3313 and the horizontal plane ranges from 15 ° to 25 °. For example, the included angle α2 between the second guide surface 3313 and the horizontal plane may be 15 °, 17 °,20 °, 22 °, 25 °, or the like. By making the included angle alpha 2 between the second diversion surface 3313 and the horizontal plane not smaller than 15 degrees, the second diversion surface 3313 can effectively diversion the external sundries on the frame top 331 so as to reduce or avoid the possibility that the external sundries accumulate on the frame top 331 and shade the air outlet of the frame top 331, and by making the included angle alpha 2 between the second diversion surface 3313 and the horizontal plane not larger than 25 degrees, the air flow can smoothly flow out from the air outlet of the frame top 331, and the flow resistance of the air flow flowing out from the air outlet of the frame top 331 is reduced.
For example, if the included angle α2 between the second guiding surface 3313 and the horizontal plane is too large, the included angle between the air outlet of the frame top 331 and the horizontal plane may be too large, which may cause the flow cross section of the air flow to be suddenly changed and increase the flow resistance of the air flow, and by making the included angle α2 between the second guiding surface 3313 and the horizontal plane not larger than 25 °, the air flow may more smoothly flow out from the air outlet of the frame top 331. The included angle alpha 2 between the second guide surface 3313 and the horizontal plane ranges from 15 degrees to 25 degrees, so that the guide effect of the second guide surface 3313 on external impurities at the top 331 of the frame and the smoothness of airflow flow can be well balanced.
Referring to fig. 5-9, according to some embodiments of the invention, the flow-directing surface extends obliquely downward in a fore-aft direction. By forming the guide surface to extend obliquely downward in the front-rear direction, foreign matters falling on the guide surface can be made to slide down in the front-rear direction, and the possibility that external foreign matters accumulate at the frame top 331 and shield the first air outlet 311 of the frame top 331 can be reduced.

For another example, the cross section of the first sub-air outlet 3111 is polygonal, the cross section of the first sub-air outlet 3111 may be quadrilateral, pentagonal, hexagonal, heptagonal or octagonal, the number of sides of the polygon is equal to or greater than 4 through the polygonal cross section of the first sub-air outlet 3111, the first sub-air outlets 3111 with polygonal cross sections may be more closely arranged, and under the condition that the area of the top 331 of the frame is fixed, the number of the first sub-air outlets 3111 may be more, so that the total air outlet area of the first sub-air outlets 3111 of the top 331 of the frame is larger, which is favorable for increasing the air outlet area of the top 331 of the frame.

In addition, when the heating element starts to defrost or snow the frame top 331, the heating power of the heating element may be adjusted according to the air output of the first air outlet 311 of the frame top 331 detected by the air volume sensor, for example, the lower the air output of the first air outlet 311 of the frame top 331 detected by the air volume sensor is, the larger the heating power may be adjusted.
