An air handler 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.
As shown in fig. 2, 4 and 5, an air handler 100 according to an embodiment of the present invention includes: a housing 1, a fan assembly 2 and an electrical heater 3. The air inlet 12 is formed in the casing 1, the air outlet duct 13 is further defined in the casing 1, the air outlet duct 13 is provided with an air outlet 131 formed in the casing 1, the cross-sectional area of the air outlet duct 13 is gradually reduced along the airflow flowing direction, the fan assembly 2 is arranged in the casing 1 to drive airflow to flow from the air inlet 12 to the air outlet 131, and the electric heating element 3 is arranged in the casing 1 to heat the airflow flowing in from the air inlet 12.
It can be understood that the housing 1 defines an accommodating space 11, the fan assembly 2 and the electric heating element 3 are located in the accommodating space 11, air in the space where the air treatment machine 100 is located enters the accommodating space 11 through the air inlet 12 and is heated by the electric heating element 3 under the driving action of the fan assembly 2, the electric heating element 3 heats the air flow and reduces the humidity of the air flow, and the heated air flow flows out of the air outlet 131 through the air outlet duct 13 under the driving action of the fan assembly 2, so that the indoor humidity is reduced. Meanwhile, compared with the air outlet duct in the prior art, the cross-sectional area of the air outlet duct 13 is unchanged, and because the cross-sectional area of the air outlet duct 13 is gradually reduced along the airflow flowing direction, the airflow speed flowing out through the air outlet duct 13 is increased under the same driving force of the fan assembly 2, so that the air supply distance of high-temperature dry airflow flowing out of the air outlet 131 is improved, and the indoor humidity is reduced, and meanwhile, the ground which is wet is dried quickly is realized. Particularly, when the air treatment machine 100 is applied to a bathroom environment, the air outlet 131 can flow out high-temperature dry air with high flow rate through the structure, so that rapid dehumidification and dry ground are realized, falling injury caused by foot slip on wet ground of a user is avoided, bacterial breeding is reduced, and use experience of the user is improved.
Further, as shown in fig. 4, the fan assembly 2 includes a driving motor 21, a centrifugal wind wheel 22 and a volute 23, the driving motor 21 is connected with the centrifugal wind wheel 22 and is used for driving the centrifugal wind wheel 22 to rotate, the centrifugal wind wheel 22 is disposed in the volute 23, and the centrifugal wind wheel 22 is driven to rotate by the driving motor 21, so that air in a space where the air treatment machine 100 is located enters the centrifugal wind wheel 22, is pressurized by the centrifugal wind wheel 22, and is discharged from the air outlet 131 through the air outlet duct 13.
Further, as shown in fig. 5, the electric heating element 3 may be disposed around the outer peripheral wall of the centrifugal wind wheel 22, so that the electric heating element 3 heats the air flow flowing into the air inlet 12 more sufficiently, and further increases the temperature of the air flow flowing out through the air outlet 131.
According to the air processor 100 of the embodiment of the invention, the air inlet 12 is arranged on the shell 1, the air outlet air duct 13 is also defined in the shell 1, the air outlet air duct 13 is provided with the air outlet 131 positioned on the shell 1, the fan assembly 2 is arranged in the shell 1 to drive air flow from the air inlet 12 to the air outlet 131, the electric heating element 3 is arranged in the shell 1 to heat the air flow flowing in from the air inlet 12, and the cross-sectional area of the air outlet air duct 13 is gradually reduced along the air flow direction, so that the air flow speed flowing out through the air outlet air duct 13 is increased under the same driving force of the fan assembly 2, the air supply distance of high-temperature dry air flow flowing out from the air outlet 131 is improved, and the indoor humidity is reduced, and the ground with moisture is quickly blown dry.
In some embodiments of the present invention, as shown in fig. 4, the case 1 includes an upper duct plate 132 and a lower duct plate 133 for defining the air outlet duct 13, the lower duct plate 133 extending in a horizontal direction, the upper duct plate 132 being inclined downward in a direction toward the air outlet 131. Through such arrangement of the upper air duct plate 132 and the lower air duct plate 133, the cross-sectional area of the air duct 13 is gradually reduced along the airflow flowing direction, and the airflow flowing out of the air outlet 131 obliquely flows downwards, so that the high temperature and dry airflow flowing out of the air outlet 131 can be blown to the ground more, and the wet ground can be dried more quickly.
In some embodiments of the present invention, as shown in fig. 2, the air inlet 12 includes a first air inlet 121, the first air inlet 121 and the air outlet 131 are both disposed on the front side of the housing 1, and the first air inlet 121 is located above the air outlet 131. It will be appreciated that the fan assembly 2 drives air to flow into the air inlet 121 at the front side of the housing 1, and flows out of the air outlet 131 at the front side of the housing 1 after being heated by the electric heating element 3, and by this arrangement, the air handler 100 can be placed against a wall, so that the space occupied by the air handler 100 is reduced, particularly when the air handler 100 is placed under the bathroom cabinet 200. Because the air outlet 131 is located below the first air inlet 121, the air outlet 131 is closer to the ground, and the high-temperature dry air flow flowing out of the air outlet 131 can quickly dry the ground.
