Alternatively, the positioning member 31 extends into the limit groove 20 when the cleaning mechanism 3 is placed on the surface of the rail assembly 2. Thus, when the filter screen needs to be cleaned, under the condition that the cleaning mechanism 3 is placed on the surface of the track assembly 2, the positioning piece 31 stretches into the limiting groove 20, so that the movement track of the cleaning mechanism 3 is limited in the movement process of the cleaning mechanism 3.
In some embodiments, as shown in fig. 6, the track assembly 2 further comprises: the guide rails 21 are symmetrically disposed on both sides of the limit groove 20 and are configured to contact with the rollers 32 of the cleaning mechanism 3.

Alternatively, the cleaning brushes 4 are symmetrically arranged on both sides of the main body. Thus, when the cleaning mechanism 3 moves along the track assembly 2, the cleaning brush 4 rotates to clean the net surfaces 1 on both sides of the track assembly 2.
In some embodiments, as shown in fig. 7-9, the body is further provided with rollers 32 that contact the track assembly 2. The roller 32 contacts the guide rail 21 and rolls along the guide rail 21, so that the cleaning mechanism 3 can move smoothly. Optionally, the main body is further provided with a driving motor (not shown in the drawings) for driving the roller to rotate.

The conductive sheet transmits electric energy from the guide rail 21 to the driving mechanism 5, so that the driving mechanism 5 works to drive the cleaning brush 4 to rotate. As the cleaning mechanism 3 moves along the track assembly 2, the conductive sheet remains in contact with the track 21 to effect power to the cleaning mechanism 3. Optionally, the conductive sheet and the cleaning brush 4 are both disposed at the front of the main body.

After the electromagnet is electrified, a magnetic field can be generated, so that the cleaning mechanism is adsorbed on the surface of the filter screen.
Fig. 1 is a schematic flow chart for controlling a filter screen cleaning mechanism according to an embodiment of the disclosure. As shown in fig. 1, an embodiment of the present disclosure provides a method for controlling a filter screen cleaning mechanism including a cleaning brush that is movable along a filter screen under the drive of a drive motor, the method for controlling the filter screen cleaning mechanism including:
s01, determining fan current of a fan corresponding to the filter screen;
s02, adjusting the operation parameters of the cleaning brush according to the fan current.
The filter screen is used for filtering impurities such as dust in the air, and can be a filter screen arranged in the air conditioner, so that the dirty air can be prevented from entering the air conditioner. When the air conditioner is used for a long time, dirt is easy to adhere to the filter screen, the filter screen is arranged at the air inlet of the air conditioner, and dirt in the air is blocked outside the air conditioner. The filter screen can be arranged at the air inlet of the air conditioner indoor unit or at the air inlet of the air conditioner outdoor unit. When the filter screen is arranged in the air conditioner indoor unit, the fan corresponding to the filter screen is a fan arranged in the air conditioner indoor unit; when the filter screen is arranged on the air conditioner outdoor unit, the fan corresponding to the filter screen is a fan arranged on the air conditioner outdoor unit. As the level of fouling increases, the current through the fan increases. Therefore, the fan current can reflect the dirt condition of the filter screen to a certain extent, and the dirt degree of the filter screen can be judged by detecting the fan current.
According to the magnitude of the detected fan current, the operation parameters of the cleaning brush are adjusted, so that the cleaning mechanism can adjust the operation condition of the cleaning brush based on the magnitude of the fan current, the cleaning strength of the cleaning mechanism to the filter screen is intelligently adjusted according to the dirt blocking condition in a targeted manner, and the self-cleaning effect of the air conditioner filter screen is improved.
In some embodiments, the operational parameters of the brush include a brush speed and/or a brush travel speed.
The driving motor is used for driving the cleaning mechanism to walk, so as to drive the cleaning brush to walk along the filter screen. The driving motor can directly drive the cleaning brush to rotate, and the cleaning brush can clean the filter screen and drive the cleaning mechanism to move when rotating. The driving motor can also drive the roller wheels arranged on the cleaning mechanism to realize walking, and the roller wheels rotate to drive the cleaning mechanism to move along the filter screen. The travel speed of the cleaning mechanism can be controlled by adjusting the drive current of the drive motor, and when the drive current of the drive motor is larger, the travel speed of the cleaning mechanism is faster, and conversely, the travel speed of the cleaning mechanism is slower. When the cleaning mechanism walks faster, the residence time of the cleaning brush on the surface of the filter screen is shorter, so that the cleaning process can be accelerated; when the cleaning mechanism walks slowly, the residence time of the cleaning brush on the surface of the filter screen is longer, and the cleaning can be carefully realized.
The cleaning brush can rotate and clean dirt on the surface of the filter screen through scratch generated between the cleaning brush and the filter screen during rotation. The cleaning frequency of the cleaning brush on the same area is different under different rotating speeds. When the cleaning brush rotates faster, the cleaning frequency of the same area is higher, and when the cleaning brush rotates slower, the cleaning frequency of the same area is lower. The rotating speed of the cleaning brush cannot be set too fast, so that the cleaning effect is improved, and the cleaning brush is quickly worn; the rotational speed of the cleaning brush cannot be set too slow, and too slow will directly cause the cleaning effect to be reduced.
The operation parameters of the cleaning brush comprise the rotating speed of the cleaning brush and/or the advancing speed of the cleaning brush, the operation parameters are adjusted, the cleaning frequency and/or the residence time of the cleaning brush to the same area can be influenced, and further different cleaning intensities are generated, and the dirt conditions of different degrees of the filter screen can be corresponding. Optionally, the filter screen surface is provided with a guide rail, and the cleaning mechanism is configured to move along the guide rail. The guide rail can limit the moving track of the cleaning mechanism on the surface of the filter screen.
In some embodiments, adjusting the operational parameters of the sweeper brush based on the fan current includes:
when the fan current is in a first current range, adjusting the rotating speed of the cleaning brush to be a first rotating speed;
When the fan current is in a second current range, adjusting the rotating speed of the cleaning brush to be a second rotating speed;
the first current range is smaller than the second current range, and the first rotating speed is smaller than the second rotating speed.
The first current range corresponds to the first dirt degree, the second current range corresponds to the second dirt degree, and different gears are adjusted on the rotating speed of the cleaning brush according to whether the fan current is in the first current range or the second current range. The first current range is smaller than the second current range, so that the first dirt degree corresponding to the first current range is lighter than the second dirt degree corresponding to the second current range, at the moment, the cleaning brush is made to be a first rotating speed under the first dirt degree and is smaller than a second rotating speed under the second dirt degree, namely, when the pollution of the filter screen is lighter, the cleaning brush cleans the filter screen at a smaller rotating speed, the cleaning of the filter screen can be realized, and the abrasion of the filter screen to the cleaning brush can be reduced; when the pollution is heavy, the dust is cleaned at a larger rotating speed, and the pollutant is cleaned from the filter screen as soon as possible. Through this embodiment, make clean mechanism can be according to the gear size of fan electric current, adjust the rotational speed of brush cleaner to realize clean mechanism's intelligence and clean.
In practical application, as shown in fig. 2, the method for controlling the filter screen cleaning mechanism includes:
s01, determining fan current of a fan corresponding to the filter screen;
S11, judging whether the fan current is in a first current range or a second current range;
s12, when the fan current is in a first current range, adjusting the rotating speed of the cleaning brush to be a first rotating speed;
and S13, when the fan current is in a second current range, adjusting the rotating speed of the cleaning brush to be a second rotating speed.
According to the fan current of the fan corresponding to the filter screen, whether the fan current is in a first current range or in a second current range is judged, so that the rotating speed of the cleaning brush is adjusted to adapt to cleaning of the filter screens with different dirt degrees.
Optionally, the first current range is defined according to a rated current of the blower. Optionally, the first current range is 1.01 to 1.05 times the rated current of the fan. When the dirt level of the filter screen is light, the fan current is 1.01-1.05 times of the rated current of the fan, and the range can be used for limiting the dirt level of the filter screen to be light. Optionally, the second current range is defined according to a rated current of the blower. Optionally, the second current range is 1.06-1.10 times of rated current of the fan. When the dirt level of the filter screen is heavy, the fan current is 1.06-1.10 times of the rated current of the fan, and the range can be used for limiting the dirt level of the filter screen. The rated current of the fan is obtained through calculation of the rated power and the voltage of the fan, and the rated power of the fan is the rated power of the fan at a high rotating speed. The high rotation speed ranges from 975r/min to 1150r/min. When the filter screen is dirty, the fan current is increased relative to the rated current. Through this embodiment, set up first electric current scope and second electric current scope according to the rated current of fan, can realize carrying out comparatively accurate judgement to the dirty stifled condition of filter screen through the fan electric current, and then can carry out more reasonable regulation to the brush cleaner.
In some embodiments, adjusting the operational parameters of the sweeper brush based on the fan current includes:
when the fan current is in a first current range, adjusting the travelling speed of the cleaning brush to be a first speed;
