It should be noted that the description manner of the water inlet chamber 101 and the deposition chamber 105 is only for the convenience of distinguishing functions of each area in the closed space formed by enclosing the upper housing 11 and the lower housing 12. In fact, in some implementation modes of the present application, the water inlet chamber 101 and the deposition chamber 105 are completely an integrated structure, namely the water inlet chamber 101 and the deposition chamber 105 are a same overall interconnected space.
The garbage filtering and collecting mechanism 5 includes a garbage basket 51 and a first fixed block 52, the first fixed block 52 is fixedly arranged on the housing 1, the garbage basket 51 covers the periphery of the third opening 106 and is detachably connected with the first fixed block 52, and a second filter screen 53 is arranged at a grid gap of the garbage basket 51.
The garbage basket 51 is a grid structure and serves as a mounting framework of the second filter screen 53, and the second filter screen 53 is filled and arranged at the grid gap of the garbage basket 51, and used to intercept the dirt in the garbage basket 51.
In this implementation mode, the garbage basket 51 is detachably connected with the first fixed block 52 by using a buckle structure, so that the garbage basket 51 may be conveniently cleaned and replaced.
The robot swimming pool cleaner 100 further includes a control mechanism (unshown), the control mechanism is electrically connected with the water pump 4, the first opening 103 is provided with a first one-way valve 6 that may be opened towards an inner side of the housing 1, the third opening 106 is provided with a second one-way valve 7 that may be opened towards an outer side of the housing 1, and the rotation direction of the water pump 4 is controlled by the control mechanism, to form a water flow from the first opening 103 to the second opening 104 inside the housing 1, or form a water flow from the second opening 104 to the third opening 106 inside the housing 1.
The second one-way valve 7 includes a movable door 71, a second fixed block 72, and a torsion spring 73, the movable door 71 is connected with the second fixed block 72 by a rotating shaft 74, so that the movable door 71 may be rotated towards the outer side of the housing 1, to open the third opening 106, and the torsion spring 73 is arranged between the movable door 71 and the second fixed block 72, so that the movable door 71 is rotated towards the inner side of the housing 1 without an external force, to shield the third opening 106.
In this implementation mode, the second fixed block 72 is fixed on the first fixed block 52, namely the second one-way valve 7 is arranged on the garbage filtering and collecting mechanism 5.
In other implementation modes, the second fixed block 72 may also be set to be fixed on the upper housing 11, namely the second one-way valve 7 is arranged on the housing 1.
In this implementation mode, the first one-way valve 6 also adopts a structure similar to the second one-way valve 7, and the difference is that the first one-way valve 6 may be rotated towards the inner side of the housing 1, to open the first opening 103.
While the robot swimming pool cleaner 100 performs the cleaning work of the swimming pool, the control mechanism controls the forward rotation of the water pump 4, and the water flow from the first opening 103 to the second opening 104 is formed in the housing 1. Specifically, the first one-way valve 6 is opened under the thrust of the water flow, water with the dirt enters the housing 1 from the first opening 103, and after being filtered by the first filter screen 32 on the filtering basket 31, the dirt is intercepted in the water inlet chamber 101, and the filtered water is discharged from the housing 1 by a water pump flow channel 8 at the second opening 104. In this process, the second one-way valve 7 keeps the third opening 106 to be in a closed state.
After the robot swimming pool cleaner 100 is operated for a period of time, the dirt may block the first filter screen 32. At this time, the control mechanism controls the water pump 4 to be reversely rotated for self-cleaning, and the water flow from the second opening 104 to the third opening 106 is formed in the housing 1. Specifically, the water flow enters the housing 1 from the water pump flow channel 8 at the second opening 104, the first filter screen 32 on the filtering basket 31 is reversely flushed, the second one-way valve 7 is opened under the thrust of the water flow, and the water flow pushes the dirt towards the deposition chamber 105 and the garbage basket 51, so that the smoothness of the first filter screen 32 is recovered. In this process, the first one-way valve 6 keeps the first opening 103 to be in the closed state.
By regularly performing the self-cleaning, the robot swimming pool cleaner 100 may maintain the higher cleaning efficiency for a longer time.
In this implementation mode, the third opening 106 is preferably arranged on an upper side of the deposition chamber 105. During the self-cleaning, under the action of gravity, the larger dirt (it is not easy to cause blockage of the first filter screen 32) may remain in the deposition chamber 105, while the smaller dirt (it is easy to cause the blockage of the first filter screen 32) may be washed into the garbage basket 51 with the water flow. By setting a relative position between the third opening 106 and the deposition chamber 105, the classification and storage of the dirt in the self-cleaning process are achieved, and the blockage process of the second filter screen 53 on the garbage basket 51 may be delayed, thereby the service time of the robot swimming pool cleaner 100 is prolonged.
In this implementation mode, the filtering mechanism 3 includes a first filter screen 32, the garbage filtering and collecting mechanism 5 includes a second filter screen 53, and the mesh aperture of the first filter screen 32 is smaller than that of the second filter screen 53. Some small dirt that may block the first filter screen 32 may pass through meshes of the second filter screen 53, thereby the blockage process of the second filter screen 53 is delayed. The robot swimming pool cleaner 100 adopting this implementation mode focuses on prolonging the service life.
In other implementation modes, the filtering mechanism 3 includes a first filter screen 32, the garbage filtering and collecting mechanism 5 includes a second filter screen 53, and the mesh aperture of the first filter screen 32 is larger than that of the second filter screen 53. The second filter screen 53 may intercept the small dirt in the garbage basket 51, and the robot swimming pool cleaner 100 adopting this implementation mode focuses on enhancing the water quality cleaning effect.
In this implementation mode, the water pump 4 includes a motor 41 and an impeller 42, an outer case of the motor 41 is provided with a threading gasket 43, the outer case and the threading gasket 43 of the motor 41 are provided with a through hole 44 for wiring, and the through hole 44 is internally provided with a waterproof sealing member. An electric connection cable of the motor 41 penetrates the through hole 44 and is sealed by the waterproof sealing member, to prevent the water from entering the interior of the motor 41.
Furthermore, the second opening 104 is provided with the water pump flow channel 8, the water pump flow channel 8 is fixedly connected with the housing 1, the impeller 42 of the water pump 4 is arranged in the water pump flow channel 8, and an outer port of the water pump flow channel 8 is provided with a guide vane 9. The water pump flow channel 8 is arranged in order to improve the working efficiency of the water pump 4.
The robot swimming pool cleaner 100 has a self-cleaning function and is convenient for use. By arranging the deposition chamber 105, the garbage filtering and collecting mechanism 5, the first one-way valve 6 and the second one-way valve 7, the water pump 4 forms a reverse water flow while being rotated reversely, the filtering mechanism 3 is flushed, dirt is flushed to the deposition chamber 105 and the garbage filtering and collecting mechanism 5 for temporary storage, the filtering mechanism 3 is avoided from being blocked, and it may be guaranteed that the robot swimming pool cleaner 100 has the higher cleaning efficiency for a longer time.
