As the utility model there are also a kind of improvement, the first straight line actuator is cylinder or hydraulic cylinder or straight-line electric Machine, by the improvement, it can be cylinder that first straight line actuator, which is the actuator that filter screen linear movement may be implemented, Or hydraulic cylinder or linear motor or any one linear drives part.

As the utility model there are also a kind of improvement, the driving mechanism includes the first rotating electric machine, the filter screen It is rotated using the axis of the first rotating electric machine as rotation axis, multiple filtration zones are sequentially set along the circumferential direction of filter screen It sets, by the improvement, the first rotating electric machine driving filter screen is rotated with switch filtering region, to avoid in preceding filtering Residue is by secondary pulse.

As a kind of also improvement of the utility model, the filter device further includes that will clean fluid flow guiding to filter screen Conduit, the driving mechanism includes the second straight line actuator for driving linear movement, and multiple filtration zones are along moving The moving direction of swing arm is set in sequence on filter screen, and by the improvement, second straight line actuator is used to move the position of conduit Set, to switch filtration zone of the cleaning fluid on filter screen, to avoid in the residue of preceding filtering by secondary pulse.

As the utility model there are also a kind of improvement, the second straight line actuator is cylinder or hydraulic cylinder or straight-line electric Machine, by the improvement, second straight line actuator is the actuator that conduit linear movement may be implemented, can for cylinder or Hydraulic cylinder or linear motor or any one linear drives part.

As a kind of also improvement of the utility model, the filter device further includes that will clean fluid flow guiding to filter screen Conduit, it along filter screen axis is the second electric rotating for being rotated of rotation axis that the driving mechanism, which includes for driving conduit, Machine, multiple filtration zones are set in sequence on filter screen along the circumferential of filter screen.

The utility model solves the above problems used another technical solution are as follows: a kind of dish-washing machine, including liner, institute State liner water outlet be equipped with the above-mentioned filter device stated, by the improvement, dish-washing machine be cleaned multiple times after cleaning fluid Filtration zone can switch over, to avoid in the residue of preceding filtering by secondary pulse.

Specific embodiment

The embodiments of the present invention are further described with reference to the accompanying drawing.

As shown in Figures 1 to 3,

A kind of filter device, including filter screen 1, the filter screen 1 include at least two filtration zones 1.1, the filtering Device further includes the driving mechanism that the filtration zone 1.1 of filtering is participated in for switch filtering net 1.

Wherein, lead to common separator and filter screen 1 is divided into multiple filtration zones 1.1.

Wherein, the driving mechanism includes first straight line actuator 2, and the first straight line driving mechanism drives filter screen 1 Mobile, multiple filtration zones 1.1 are set in sequence on filter screen 1 along the moving direction of filter screen 1.
