Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning, in particular to a self-cleaning fresh air fan with high ventilation efficiency. Background Art

[0002] The fresh air fan is an effective air purification equipment that can circulate indoor air. On the one hand, it discharges the polluted indoor air to the outside, and on the other hand, it inputs the fresh outdoor air into the room after sterilization, disinfection, filtration and other measures, so that the room is filled with fresh and clean air at all times. The fresh air fan is mainly divided into two types: exhaust-type fresh air fan and supply-type fresh air fan. It can be installed in most indoor environments and is easy to install and comfortable to use.

[0003] During the use of existing fresh air fans, since it is necessary to discharge the dirty indoor air to the outdoors through the exhaust duct, impurities contained in the air will be adsorbed on the inner wall of the exhaust duct over a long period of time. However, the existing exhaust fans do not have the function of cleaning the exhaust outlet, which reduces the efficiency of the fresh air fan. Secondly, the operation of the existing exhaust duct during installation on the back of the fresh air fan is relatively complicated, which leads to a waste of time and reduces work efficiency. For this reason, we propose a self-cleaning fresh air fan with outdoor exhaust outlet.

[0004] The prior art discloses a patent with a publication number of CN217154431U, which includes a fresh air machine body, a mounting hole is provided on the back of the fresh air machine body, a rotating groove is provided on the inner side of the mounting hole, an exhaust duct is movably mounted on the back of the fresh air machine body, a mounting ear is fixed on the exhaust duct, and the exhaust duct is movably mounted on the back of the fresh air machine body through the mounting ear. The outdoor exhaust outlet self-cleaning fresh air machine is provided with a mounting hole, a rotating groove and a mounting ear. When the exhaust duct needs to be installed on the back of the fresh air machine body, the mounting ear is aligned with the mounting hole and inserted into the inner cavity of the side wall of the fresh air machine body, and then the exhaust duct is rotated so that the position of the mounting ear and the mounting hole are staggered, so that the exhaust duct is installed on the back of the fresh air machine body. When the exhaust duct needs to be disassembled, it only needs to be performed in reverse, thereby simplifying the installation steps of the exhaust duct and improving the work efficiency when installing the fresh air machine.

[0005] As the existing devices including the above patents are used, the shortcomings of the technology are gradually exposed, which are mainly manifested in the following aspects:

[0006] First, when the existing fresh air fan is in use, when the filter is clogged with large particles, the box needs to be disassembled, and the large particles inside need to be cleaned and discharged, which increases the labor intensity.

[0007] Secondly, when the existing fresh air fan discharges the indoor air to the outside for ventilation, it needs to pass through the filter component, which affects the air flow and reduces the ventilation efficiency.

[0008] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0010] In order to solve the above problems, the utility model provides the following technical solutions:

[0011] A self-cleaning fresh air blower with high ventilation efficiency comprises a box body, wherein an air inlet cylinder connected to the outside is fixedly connected to the box body, and a filter hole area is opened on the inner wall of the box body.

[0012] A support shell is fixedly connected horizontally inside the box body, a partition is fixedly connected horizontally inside the support shell, and the inner cavity of the support shell is divided into an air inlet channel and an air outlet channel from top to bottom by the partition, and a plurality of filter core plates are detachably installed in the air inlet channel, the opposite end walls of the support shell are opened, the inner port is connected to the inner cavity of the box body, and the outer port is connected to the room, and an axial flow fan is arranged between the inner port of the support shell and the filter hole area,

[0013] A valve plate for alternately opening and closing the air inlet passage and the air outlet passage is swingably disposed in the box.

[0014] As an optimized solution, the filter hole area is opened in the area where the air intake cylinder is above the axis, and a cleaning plate is provided on the inner wall of the air intake cylinder to rotate along the circumferential direction and to be in frictional contact with the filter hole area.

[0015] As an optimized solution, a knob is horizontally rotatable on the outer wall of the box, the inner end of the air intake cylinder is fixedly connected to the inner wall of the box, the end of the knob extends into the air intake cylinder and is vertically fixedly connected to a connecting rod, and one end of the cleaning plate is fixedly connected to the connecting rod.

[0016] As an optimized solution, the hinged end of the valve plate is hinged to the inner end of the partition by a rotating shaft, the upper and lower end walls of the inner end of the support shell are respectively fixed with a first magnetic block, and the opposite end wall of the swing end of the valve plate is fixed with a second magnetic block matching the first magnetic block.

[0017] As an optimized solution, the upper and lower end walls of the inner end of the support shell are respectively provided with grooves, and the first magnetic block is fixedly connected in the grooves.

[0018] As an optimized solution, one end of the rotating shaft passes through the supporting shell, extends to the outside and is fixedly connected with a conversion knob.

[0019] As an optimized solution, an air outlet guide plate is fixedly connected obliquely to the area of ​​the inner end of the air inlet cylinder below the filter hole area.

[0020] As an optimized solution, the box body is located above the axial flow fan and is fixedly connected with an air inlet guide plate obliquely between the lower edge of the inner end of the support shell.

[0021] As an optimized solution, an air inlet through hole area and an air outlet through hole area for connecting the air inlet channel with the air outlet channel in the room are provided on the side wall of the box body.

When fresh air needs to be introduced, the valve plate is swung downward to close the air outlet channel, and the axial flow fan rotates forward to allow air to pass through the filter hole area and the filter element plate into the room. When ventilation is required, the valve plate is swung upward to close the air inlet channel, and the axial flow fan rotates reversely to discharge the air along the air outlet channel and the air inlet to the outside. Since there is no filter element plate, the air flow can be accelerated and the ventilation efficiency can be improved.

[0026] As fresh air is introduced, when a large number of particles adhere to the inner wall of the filter hole area, the axial flow fan is reversed to start the ventilation mode. At the same time, the knob is turned to drive the cleaning plate to clean the filter hole area. The scraped particles are discharged to the outside along the air inlet pipe through the ventilation wind, realizing automatic cleaning and export of particulate matter and reducing labor intensity.
