The driving assembly 30 is disposed on the support base 10 and includes a moving member 31 capable of moving between a first position and a second position, where the first position and the second position may be fixed point positions or fixed areas, respectively.

The filter element 20 is mounted in place when the moving member 31 is in the first position, and the filter element 20 is not mounted in place when the moving member 31 is in the second position and/or when the moving member 31 is between the first position and the second position (as shown in fig. 1 where the moving member 31 is). The switch control assembly 40 is switchable between an energized state and a de-energized state, and the switch control assembly 40 is configured to be in the energized state when the filter element 20 is in place and in the de-energized state when the filter element 20 is not in place.

The power-on state and the power-off state refer to two states after the clothes treatment device is electrically connected with the external power supply, for example, a power plug of the clothes treatment device is plugged in a jack of the external power supply, and a main switch of the clothes treatment device is started; and when the laundry treating apparatus is not connected to the external power source, it is apparent that the switching control assembly is in the power-off state even when the filter member 20 is mounted in place, as will be understood by those skilled in the art.

According to the filtering device 100 for the clothes treating device of the embodiment of the invention, by arranging the driving assembly 30 and the switch control assembly 40, the installation state of the filtering element 20 and the on-off state of the switch control assembly 40 can be associated, namely, when the filtering element 20 is installed in place, the switch control assembly 40 is in the power-on state, the clothes treating device can normally work at the moment, when the filtering element 20 is not installed in place, the switch control assembly 40 is in the power-off state, the clothes treating device can not normally work at the moment, so that a user can judge whether the filtering element 20 is installed in place or not according to the running state of the clothes treating device, so as to remind the user to check whether the filtering element 20 is installed in place or not and whether cleaning is carried out or not before starting the clothes treating device to work, and the problem that the filtering element 20 is not installed.

According to an embodiment of the present invention, the laundry treating apparatus includes a drum (not shown), and the drum is configured to be rotatable when the switching control assembly 40 is in the power-on state and not rotatable when the switching control assembly 40 is in the power-off state.

Specifically, when the moving member 31 is located at the first position, the filter element 20 is mounted in place, and the switch control assembly 40 is in the power-on state, the drum body can rotate as required or according to the program setting, that is, the laundry treating apparatus can work normally; when the moving member 31 is located at the second position, or the moving member 31 is located at a position between the first position and the second position, the filter element 20 is not installed in place, and at this time, the switch control assembly 40 is in the power-off state, and the drum body cannot normally rotate, that is, the laundry treating apparatus cannot normally operate.

Like this, force the user to require before the operation at every turn and inspect filtering piece 20 to remind the user whether the check filtering piece 20 installed in place and whether clear up before the operation at every turn, ensure not to produce because filtering piece 20 neglected loading and the potential safety hazard that in time clear up and bring.

In some examples, the support seat 10 is provided at the open end of the barrel, and the opening 12 is disposed toward the inner cavity side of the barrel. That is, the user can insert the filter element 20 into the receiving cavity 11 of the support base 10 from one side in the cartridge body, thereby facilitating the assembly, disassembly, cleaning, and replacement of the filter element 20.

According to one embodiment of the present invention, the drive assembly 30 further comprises: a movable push rod 32 and an electromagnetic drive 33. The push rod 32 is used for locking the moving member 31 at the first position and/or the second position, and the electromagnetic driving member 33 is connected with the push rod 32 and used for driving the push rod 32 to move.

Specifically, as shown in fig. 3, the moving member 31 is movable in the up-down direction, the push rod 32 is movable in the left-right direction, and when the moving member 31 moves down to the first position, the push rod 32 stops at the top end of the head 312 of the moving member 31, so as to block the moving member 31 from moving up, that is, the push rod 32 locks the moving member 31 at the first position; when the moving member 31 moves upward to the second position, the push rod 32 stops at the bottom end of the head 312 of the moving member 31, so as to block the moving member 31 from moving downward, i.e. the push rod 32 locks the moving member 31 at the second position.

In some examples, the switch control assembly 40 is disposed adjacent the drive assembly 30, and the push rod 32, when moved, toggles the switch control assembly 40 between the energized state and the de-energized state. Therefore, by arranging the push rod 32 and the electromagnetic driving part 33, the push rod 32 can drive the switch control assembly 40 to switch between the power-on state and the power-off state while moving, so that the installation state of the filter element 20 is associated with the on-off state of the switch control assembly 40, and the potential safety hazard caused by the missed installation and the untimely cleaning of the filter element 20 is avoided.

In some examples, the push rod 32 has a first end 321 (left end as shown in fig. 3) and a second end 322 (right end as shown in fig. 3), the first end 321 is connected to the electromagnetic driving element 33, and the second end 322 has a pushing surface extending from the first end 321 to the second end 322 along the moving direction (left-right direction as shown in fig. 3) of the push rod 32 and gradually away from the switch control assembly 40, and the pushing surface is used for driving the switch control assembly 40 to switch between the power-on state and the power-off state.

In some specific examples, the switch control assembly 40 has a switch button, and the side of the second end 322 of the push rod 32 facing the switch button has a push surface, which may be beveled or curved. The push surface presses the switch button when the push rod 32 moves rightward, and releases the switch button when the push rod 32 moves leftward, thereby controlling the switch control assembly 40 to switch between the power-on state and the power-off state.

In some examples, the mover 31 includes: a stem portion 311 and a head portion 312, the stem portion 311 extending in the up-down direction, one end (an upper end as viewed in fig. 3) of the stem portion 311 being disposed adjacent to the filter member 20, the head portion 312 being connected to the other end (a lower end as viewed in fig. 3) of the stem portion 311, and the cross-sectional area of the head portion 312 being larger than that of the stem portion 311.

When the push rod 32 moves to the side of the head 312 facing the rod 311 (the top end of the head 312 shown in fig. 3), the push rod 32 locks the moving member 31 at the first position, and when the push rod 32 moves to the side of the head 312 facing away from the rod 311 (the bottom end of the head 312 shown in fig. 3), the push rod 32 locks the moving member 31 at the second position. Through setting up pole portion 311 and head 312 for push rod 32 can cooperate with the top and the bottom of head 312 respectively, thereby locks moving member 31 in first position, second position, and simple structure, compactness easily realize.

In some optional examples, the drive assembly 30 further comprises: an elastic element 341 (e.g., a spring) is disposed between the mounting cavity 34, a side of the head 312 facing away from the rod 311, and an inner wall surface (a bottom surface as shown in fig. 3) of the mounting cavity 34.

When the filter element 20 is inserted in the housing cavity 11, the filter element 20 pushes the moving element 31 to move downwards, thereby compressing the elastic element 341; when the push rod 32 is moved leftward, the push rod 32 is disengaged from the moving member 31, and the moving member 31 is moved upward by the restoring force of the elastic member 341, thereby ejecting the filter member 20. Therefore, by providing the elastic element 341, the moving member 31 can be driven to move by the elastic force of the elastic element 341, so as to drive at least a part of the filter member 20 to pop out from the accommodating cavity 11, thereby facilitating the removal of the filter member 20.

As shown in fig. 3, according to an embodiment of the present invention, the push rod 32 is movable in a lateral direction (left-right direction as shown in fig. 3), the moving member 31 is movable in a longitudinal direction (up-down direction as shown in fig. 3), and the longitudinal direction extends in the inside-outside direction of the opening 12 of the accommodating chamber 11. Therefore, the push rod 32 and the moving direction of the moving piece 31 are vertically arranged, so that the occupied space of the driving assembly 30 can be reduced, unlocking and locking matching of the push rod and the moving piece are facilitated, and the operability is high.
