The working principle is as follows:
after the air conditioner is installed, the fan 3 is started to work, and in the working process, the fan continuously conveys outside air to the room after passing through the air inlet end filtering device and the air outlet end filtering device;
in the using process, a lot of dirt is adhered to the air inlet end filtering device and the air outlet end filtering device the longer the time is, firstly, the dirty air is filtered by the coarse filtering net layers in the air inlet end filtering device in sequence to remove larger dirt, then the air passes through the immobilized microorganism plate and enters the granular soil layer, the air is further adsorbed by the particle soil layer, the density of the particle soil layer cannot be too high, otherwise the air circulation speed is influenced, finally, the air enters between the air inlet end filtering device and the air outlet end filtering device after passing through the fine filtering net layer, then the air passes through the air outlet end filtering device, the single breathable film and the filtering net layer under the action of air pressure and enters the room; the filter screen layer has the function of preventing indoor air from entering the heating ventilation air conditioner body, and the single air-permeable film can further prevent the indoor air from entering the heating ventilation air conditioner body; as for the indoor air flowing out of the room, other modes are adopted, and the invention only describes the treatment mode when the outdoor air enters the room in the heating ventilation air conditioner;
in the using process, dirt can be attached to the air inlet end filtering device and the air outlet end filtering device, cleaning devices are arranged on the surfaces of the air inlet end filtering device and the air outlet end filtering device, when people feel that the wind power of the air conditioner is weakened, or a flowmeter is arranged at one end, far away from a fan, of the air inlet end filtering device, when the wind power is reduced to a certain degree, information is transmitted to a controller, the controller starts a motor to work, so that the cleaning brushes clean the surfaces of the air inlet end filtering device and the air outlet end filtering device, the controller controls the motor to work, and the cleaning brushes on the crawler belts can be driven to rotate for one circle or several circles and then stop automatically; for example, the hvac has 5 gears, which can control the fan to reach five wind levels, for example, 10, 20, 30, 40 and 50, respectively, and the flow rates detected by the flow meters of the inlet end filter device and the outlet end filter device under the effect of no dirt obstruction should be 9, 18, 27, 36 and 45, however, when the flow rates detected by the flow meters are 7, 14, 21, 28 and 35, respectively, the controller controls the motor to work;
when dirt is attached to the surface of the air inlet end filtering device, the dirt can be seen artificially, so that the air inlet end filtering device can be cleaned, the cleaning times are more, however, when the dirt is attached to the surface of the air outlet end filtering device, people cannot see the dirt, and in addition, the flow meter can also have the condition of inaccurate detection result in the long-time use process, so that a wind pressure switch is added for control, as shown in fig. 5, when the dirt is attached to the surface of the air outlet end filtering device, the pressure of wind pressure on a rubber plug is increased, and further, the first electrode block and the second electrode block can be contacted, so that the controller is triggered to work;
as described above, the wind power of the fan can be adjusted, when the wind power is large, even if the air outlet end filtering device does not have dirt attached, the pressure of the wind power on the rubber plug can be increased, in order to avoid the contact between the first electrode block and the second electrode block caused by the situation, the side surface of the rubber plug close to the connecting column is provided with the magnet, the switch slot is internally provided with the electromagnet, the larger the gear of the fan is, the larger the repulsive force of the electromagnet on the magnet is, the cleaning devices corresponding to the air inlet end filtering device and the air outlet end filtering device are respectively controlled by the controller, and the times that the air inlet end filtering device needs to remove the dirt are much more than the times that the air outlet end filtering device needs to remove the;
as shown in fig. 6, 8 and 9, as mentioned above, the number of times that the air inlet end filter device needs to remove the dirt is much greater than the number of times that the air outlet end filter device needs to remove the dirt, which results in that the service life of the air inlet end filter device may be shorter, which results in that the number of times of replacement thereof may be greater, and the specific situation depends on different places of use, such as yellow mountain Anhui, the air is fresh, the dirt is less, the air inlet end filter device may not need to be replaced, and if in a region with serious environmental pollution, the number of times of replacement may be greater, based on which, the invention adopts an air inlet end filter device which is convenient to install;
as shown in fig. 6, when the air conditioner is installed, the air inlet end filtering device is put into the heating ventilation air conditioner body from the air inlet end, and at the moment, the right-angle trapezoidal block is compressed inwards under the extrusion of the inner wall of the heating ventilation air conditioner body;
as shown in fig. 8, after the top end of the right-angled trapezoid block starts to enter the installation groove, the right-angled trapezoid block instantly rises under the action of the second spring, so as to enter the installation groove, and the air inlet end filtering device can be well fastened under the action of the fastening cone and the cone groove;
if to the air inlet end filter equipment that needs often to change, be connected with magnet in right angle trapezoidal piece bottom surface, the bottom is provided with the electro-magnet in the spread groove, is provided with electro-magnet switch and small-size power on the connected frame surface, also can set up the jack, realizes the electricity through external power supply's mode and connects to make the electro-magnet circular telegram produce magnetic force through electro-magnet switch and attract magnet, and then make in the indentation spread groove of right angle trapezoidal piece, thereby realize following the warm internal dismantlement of logical air conditioner with air inlet end filter equipment.
The above; but are merely preferred embodiments of the invention; the scope of the invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; the technical scheme and the improved concept of the invention are equally replaced or changed; are intended to be covered by the scope of the present invention.
