FIELD
[0001] The present disclosure relates to a field of washing machines, and more particularly,
to a filter box assembly for a washing machine and a washing machine having the same.
BACKGROUND
[0002] It is pointed out in the related art that, during operation, a draining pump at a
lower portion of a washing machine will collect accumulated small foreign matters
such as fabric scraps, buttons, coins and the like. Generally, a user will periodically
open a box cover of a filter box outside of the draining pump to clear the accumulated
foreign matters. The box cover usually needs to be opened through a tool. For example,
the tool (such as a key, a coin, a slotted screwdriver and the like) may be adopted
to press the box cover down at a notch thereof, such that a snapping rib at the rear
of the box cover opposite to the notch may be bent downwards, so as to depart from
a snapping-rib position in the filter box, and thus the box cover may be opened. Then,
a lid of the draining pump is unscrewed and those accumulated foreign matters are
taken out, thereby ensuring the washing machine to drain water normally. However,
this manner in which the box cover is opened may cause the snapping rib of the box
cover to be deformed and damaged after a long time use, thus resulting in that the
box cover cannot be closed, and thereby influencing an overall appearance of the washing
machine.
[0003] EP 1 826 308 A1 discloses a device for closing and opening the access to a compartment, in which
said access is formed in a wall of the structure of a machine, comprising a hatch
displaceable about a virtual axis of rotation between a first position where it is
arranged over the access of the said compartment, causing closing thereof, and a second
position, angularly displaced with respect to the first position, where the access
to the compartment is free, as well as resilient recall means acting on said hatch.
A conventional resilient tongue is intended to engage with a lug formed on the edge
of the access and ensures that the hatch is kept in the closed position.
[0004] From
EP 1 462 597 A1 a locking device for a cover and the like is known which is locked by a first push
and unlocked by a second push, comprising: a case which comprises, located at a work
face (8), an elastic leg provided with a follower; a sliding member which comprises,
parallel to said work face, a planar cam surface from which projects a central island
about which is formed a cam track for the follower; with, on the first push, the follower
passing from its free position to its captive position by a first path on the cam
track and, on the second push, the follower passing from its captive position to its
free position by a second path distinct from the first path

DETAILED DESCRIPTION
[0020] Reference will be made in detail to embodiments of the present disclosure. The same
or similar elements and the elements having same or similar functions are denoted
by like reference numerals throughout the descriptions. The embodiments described
herein with reference to drawings are explanatory, illustrative, and used to generally
understand the present disclosure. The embodiments shall not be construed to limit
the present disclosure.
[0021] Various embodiments and examples are provided in the following description to implement
different structures of the present disclosure. In order to simplify the present disclosure,
certain elements and settings will be described. However, these elements and settings
are only by way of example and are not intended to limit the present disclosure. In
addition, reference numerals may be repeated in different examples in the present
disclosure. This repeating is for the purpose of simplification and clarity and does
not refer to relations between different embodiments and/or settings. Furthermore,
examples of different processes and materials are provided in the present disclosure.
However, it would be appreciated by those skilled in the art that other processes
and/or materials may be also applied.
[0022] A filter box assembly 200 for a washing machine (not shown in the drawings) according
to a first aspect of embodiments of the present disclosure will be described with
reference to Figs. 1-24 in the following. Optionally, the washing machine may be a
drum washing machine or a pulsator washing machine, and only the drum washing machine
is taken as an example of the washing machine for explanations in the following. Certainly,
after reading a technical solution below, those skilled in the art obviously understand
a technical solution in which the washing machine is configured as the pulsator washing
machine. Specifically, referring to Figs. 1 and 2, the washing machine (such as the
drum washing machine) may include a machine body (not shown in the drawings) and a
front sealing door 100, and the front sealing door 100 may be vertically covered over
a front end of the machine body. The front sealing door 100 may have a mounting hole
at a bottom right corner thereof, and the mounting hole runs through the front sealing
door 100 along a front and rear direction. The filter box assembly 200 is mounted
in the mounting hole.
[0023] As shown in Figs. 3-8, the filter box assembly 200 for the washing machine according
to the first aspect of embodiments of the present disclosure includes: a box cover
1 and a box body 2. The box cover 1 is provided with a lock tongue 11, and the box
body 2 is provided with a lock catch mechanism 3. The box body 2 is connected with
or disconnected from the box cover 1 through the lock tongue 11 and the lock catch
mechanism 3. Specifically, when the box cover 1 is located at a position where the
box body 2 is open (as shown in Fig. 2 and Figs. 4-8), if the box cover 1 is pushed
towards the box body 2, the lock tongue 11 and the lock catch mechanism 3 are locked
and connected mutually, such that the box cover 1 may remain at a position where the
box body 2 is closed (as shown in Figs. 1 and 3). When the box cover 1 is located
at the position where the box body 2 is closed (as shown in Figs. 1 and 3), if the
box cover 1 is pushed towards the box body 2, the lock tongue 11 and the lock catch
mechanism 3 are separated and disengaged from each other, such that the box cover
1 may move in a direction of opening the box body 2 so as to open the box body 2 (as
shown in Fig. 2 and Figs. 4-8).
[0024] For example, in examples shown in Figs. 3-8, the box body 2 is generally formed as
a cuboid arranged vertically, and defines an accommodating space with an open front
side therein. The box cover 1 is generally formed as a rectangle plate, and is vertically
disposed at the front of the box body 2. A bottom portion of the box cover 1 is pivotably
connected with a front side of a bottom portion of the box body 2. A rear side of
a top portion of the box cover 1 may be provided with the lock tongue 11 and a top
portion of the box body 2 may be provided with the lock catch mechanism 3. When the
lock tongue 11 is well fitted with the lock catch mechanism 3, the top portion of
the box cover 1 is closely fitted and connected with the top portion of the box body
2, and thus the box cover 1 may seal a front side of the box body 2 completely, so
as to close the box body 2 (as shown in Figs. 1 and 3). When the lock tongue 11 is
separated from and disengaged from the lock catch mechanism 3, the top portion of
the box cover 1 is separated from the top portion of the box body 2, in which case
the box cover 1 may be pivoted forwards, so as to open the box body 2 (as shown in
Fig. 2 and Figs. 4-8).
[0025] Referring to Fig. 3, when the box cover 1 is located at the position where the box
body 2 is closed, if the box cover 1 is pushed backwards, the lock tongue 11 may be
disengaged from the lock catch mechanism 3, such that the box cover 1 may be opened
forwards (as shown in Figs. 4-8), as shown in Figs. 4-8. When the box cover 1 is located
at the position where the box body 2 is open, if the box cover 1 is pushed backwards,
the lock tongue 11 may be well fitted with the lock catch mechanism 3, such that the
box cover 1 may remain at the position where the box cover 2 is closed (as shown in
Fig. 3). Thus, when the washing machine operates normally, the box cover 1 is located
at the position where the box body 2 is closed (as shown in Figs. 1 and 3). When the
box cover 1 of the filter box assembly 200 needs to be opened to clear debris, a user
may open the box cover 1 just by slightly tapping the box cover 1 inwards manually
at an outer side of the box cover 1. When the box cover 1 of the filter box assembly
200 needs to be closed, the user may close the box cover 1 and lock the box cover
1 to the box body 2 just by slightly pushing (pressing) the box cover 1 upwards and
inwards.
[0026] Thus, the box cover 1 may be opened and closed by an action of pushing the box cover
1 towards the box body 2, thereby improving operational convenience of the filter
box assembly 200. Thus, the user may easily open and close the box cover 1 without
adopting a tool. Moreover, a mechanical fit between the lock tongue 11 and the lock
catch mechanism 3 has high reliability and is not easy to damage, thereby improving
a service life of the filter box assembly 200 and an aesthetic property of the overall
washing machine.
[0027] In the filter box assembly 200 for the washing machine according to embodiments of
the present disclosure, by the fit between the locking tongue 11 and the lock catch
mechanism 3, the user may open and close the box cover 1 just by pushing the box cover
1, and thus the operational convenience of the filter box assembly 200 is effectively
improved. Moreover, the fit between the locking tongue 11 and the lock catch mechanism
3 is high in reliability and not easy to damage, such that the service life of the
filter box assembly 200 and the aesthetic property of the overall washing machine
are improved.
[0028] In an embodiment of the present disclosure, the lock catch mechanism 3 may be mounted
to the box body 2 by assembling. For example, in examples shown in Figs. 4-8, a top
wall of the box body 2 may be provided with a through hole running therethrough in
the front and rear direction, and the lock catch mechanism 3 may be mounted in the
through hole. Optionally, as shown in Figs. 9-14, the lock catch mechanism 3 may be
generally configured to have a cuboid shape, and a left side wall and a right side
wall of the lock catch mechanism 3 each may be provided with an elastic buckle 4 respectively.
A rear end of the elastic buckle 4 is a fixed end and may be fixedly connected with
a rear end of a side wall of the lock catch mechanism 3, and a front end of the elastic
buckle 4 is a free end and may extend in a direction running away from a center of
the lock catch mechanism 3.
[0029] Referring to Figs. 8 and 9, when the lock catch mechanism 3 is mounted, the front
ends of the two elastic buckles 4 may be clamped to the two side walls of the lock
catch mechanism 3 respectively, and then the lock catch mechanism 3 may be pushed
from front to rear to pass through the through hole in the box body 2. Subsequently,
the two elastic buckles 4 recover their original shapes. That is, the front ends of
the two elastic buckles 4 may spring in the direction running away from the center
of the lock catch mechanism 3 respectively, such that a distance between the front
ends of the two elastic buckles 4 in a left and right direction is larger than a width
of a rear side of the through hole. In this way, even if the lock catch mechanism
3 is pushed forwards, the front ends of the two elastic buckles 4 may abut against
wall surfaces at two sides of a rear end of the through hole, so as to prevent the
lock catch mechanism 3 from moving forwards. Thus, by the two elastic buckles 4, the
lock catch mechanism 3 may be firmly and easily mounted to the box body 2. Certainly,
the present disclosure is not limited to this, and the lock catch mechanism 3 may
be assembled with the box body 2 in other manners. In addition, the lock catch mechanism
3 may be integrally formed with the box body 2, which is not elaborated herein.
[0030] In an embodiment of the present disclosure, referring to Fig. 15, the lock catch
mechanism 3 may include: a locking seat 31, a locking block 32 and a rolling member
33 (for example a ball). The locking block 32 may be fitted in the locking seat 31
in a retractable manner. That is, the locking block 32 may move between a position
where the locking block 32 extends out of the locking seat 31 and a position where
the locking block 32 is retracted in the locking seat 31. When the locking block 32
is retracted in the locking seat 31, the lock tongue 11 may be locked. When at least
part of the locking block 32 extends out of the locking seat 31, the lock tongue 11
may be released. For example, in an example shown in Fig. 15, the locking block 32
may slide forwards and backwards in the locking seat 31. When the locking block 32
slides backwards to be completely received in the locking seat 31, the locking block
32 may lock the locking tongue 11, such that the box cover 1 is closed to the box
body 2. When the locking block 32 moves forwards to extend out of the locking seat
31, the locking block 32 releases the locking tongue 11, such that the box cover 1
opens the box body 2.
[0031] For example, in a specific example of the present disclosure, referring to Fig. 15,
the locking seat 31 is provided with an accommodating groove 3111, and the locking
block 32 may move forwards and backwards in the accommodating groove 3111. The locking
block 32 is provided with a locking claw 322. When the locking block 32 drives the
locking claw 322 to move until the locking claw 322 is retracted in the accommodating
groove 3111, the locking claw 322 locks the locking tongue 11. When the locking block
32 drives the locking claw 322 to move until the locking claw 322 departs from the
accommodating groove 3111, the locking claw 322 releases the locking tongue 11.
[0032] Referring to Fig. 15, the accommodating groove 3111 may be formed by being recessed
backwards from a front end surface of the locking seat 31, and the locking block 32
may be fitted in the accommodating groove 3111. The locking block 32 may move backwards
into the accommodating groove 3111 and move forwards out of the locking block 32.
A left side and a right side of the locking block 32 each may be provided with one
locking claw 322 respectively. The locking claw 322 is configured as an elastic member.
A rear end of the locking claw 322 may be fixedly connected with the locking block
32, and a front end of the locking claw 322 is free and extends forwards and outwards
(in a direction running away from a center axis of the locking block 32). A front
end of each locking claw 322 is provided with a clasping portion 3221 at an inner
side (a side adjacent to the center axis of the locking block 32) thereof. Referring
to Fig. 8, the locking tongue 11 includes a neck portion 111 and a head portion 112.
The neck portion 111 extends backwards from a rear-end surface of the box cover 1,
and the head portion 112 extends backwards from a rear end of the neck portion 111.
A width of the head portion 112 in the left and right direction is larger than a width
of the neck portion 111 in the left and right direction.
[0033] Thus, referring to Figs. 8 and 15, when the locking block 32 drives the locking claw
322 to move backwards so as to be received into the accommodating groove 3111, the
respective front ends of the two locking claws 322 are inclined towards the center
axis of the locking block 32, and a distance between the two clasping portions 3221
in the left and right direction is reduced, such that the two clasping portions 3221
clasp the neck portion 111 of the locking tongue 11, and thus the head portion 112
of the locking tongue 11 is restricted between the two clasping portions 3221 and
a front end of the locking block 32, in which case the locking claws 322 lock the
locking tongue 11. When the locking block 32 drives the locking claw 322 to move forwards
out of the accommodating groove 3111, the respective front ends of the two locking
claws 322 are inclined in the direction running away from the center axis of the locking
block 32, so as to recover their original shapes, and the distance between the two
clasping portions 3221 in the left and right direction is increased, such that the
two clasping portions 3221 release the neck portion 111 of the locking tongue 11,
and thus the head portion 112 of the locking tongue 11 escapes forwards out of the
two clasping portions 3221 and the front end of the locking block 32, in which case
the locking claws 322 release the locking tongue 11.
[0034] Herein, it should be noted that the locking claw 322 is simple in structure, easy
to achieve, and high in reliability. Certainly, the present disclosure is not limited
to this, and the locking tongue 11 may be locked and released by the locking block
32 by means of other mechanisms with a catching and releasing function, which is not
elaborated herein.
[0035] Optionally, the lock catch mechanism may further include a tension spring 35. The
tension spring 35 is disposed between the locking block 32 and the locking seat 31
and is configured to constantly push the locking block 32 to move in a direction of
extending out of the locking seat 31. Referring to Fig. 15, the tension spring 35
may be mounted in the accommodating groove 3111, and the tension spring 35 is located
between a rear wall of the accommodating groove 3111 and a rear wall of the locking
block 32. The tension spring 35 may extend and retract freely in the front and rear
direction, such that a front end of the tension spring 35 may be connected with the
rear end of the locking block 32 (for example, the front end of the tension spring
35 may be fitted over a mounting column 323 at the rear end of the locking block 32
shown in Fig. 15), and a rear end of the tension spring 35 abuts against the rear
wall of the accommodating groove 3111 and is connected thereto.
[0036] Thus, when the locking block 32 is locked in the accommodating groove 3111, the locking
claw 322 locks the locking tongue 11, and the tension spring 35 is in a compressed
state. In this case, the tension spring 35 has an elastic force capable of ejecting
the locking block 32 forwards. When the locking block 32 is unlocked, the tension
spring 35 ejects the locking block 32 forwards, and the locking claw 322 releases
the locking tongue 11. Herein, it should be noted that the tension spring 35 is simple
in structure, easy to achieve and high in reliability. Certainly, the present disclosure
is not limited to this, and the tension spring 35 may further be replaced by other
mechanism having an elasticity function, which is not elaborated herein.
[0037] Thus, when the box cover 1 is at an open position, if the user pushes the box cover
1 towards the box body 2, the locking block 32 may be locked in the accommodating
groove 3111, such that the lock catch mechanism 3 is locked with the locking tongue
11, in which case the box body 2 is closed by the box cover 1. When the user pushes
the box cover 1 towards the box body 2 again, the locking block 32 may be unlocked,
the lock catch mechanism 3 is separated from and disengaged from the locking tongue
11, and the tension spring 35 pushes the locking block 32 forwards, such that the
box body 2 is opened by the box cover 1. By pushing the box cover 1 repeatedly like
this, the box cover 1 may be opened and closed alternately. Referring to Figs. 15-24,
a specific embodiment in which the locking block 32 can be locked in the accommodating
groove 3111 and the locking block 32 can also be unlocked will be described in detail
in the following.
[0038] Referring to Fig. 15, optionally, the locking seat 31 includes a seat body 311 and
a cover body 312. The cover body 312 may be covered on a top portion of the seat body
311, and the seat body 311 may be connected with the cover body 312 by interference
fit between four mounting pillars and four mounting holes. The accommodating groove
3111 may be recessed backwards from a front-end surface of the seat body 311. Certainly,
a structure of the locking seat 31 is not limited to this.
[0039] Specifically, referring to Figs. 15 and 16, the locking seat 31 defines a rolling
groove 3121 therein. For example, the rolling groove 3121 may be formed in a bottom
portion of the cover body 312, and the rolling groove 3121 defines a closed loop therein,
such that a rolling member 33 described below may circularly roll in the rolling groove
3121 along one direction (for example along a clockwise direction or a counterclockwise
direction). The locking block 32 is provided with a sliding groove 321 which extends
in a direction perpendicular to a moving direction of the locking block 32. For example,
in an example shown in Fig. 15, the sliding groove 321 extends along the left and
right direction, such that the rolling member 33 described in the following may slide
in the sliding groove 321 along the left and right direction repeatedly. The rolling
member 33 may be rollably clamped between the rolling groove 3121 and the sliding
groove 321, such that the rolling member 33 may roll in the rolling groove 3121 circularly,
meanwhile sliding in the sliding groove 321 along the left and right direction repeatedly.
[0040] Specifically, during an unidirectional and circular rolling of the rolling member
33 along the rolling groove 3121, when the rolling member 33 rolls to a first position
3121E (as shown in Fig. 16) in the rolling groove 3121, the locking block 32 moves
into the locking seat 31 to lock the locking tongue 11, in which case the box cover
1 may remain at the position where the box body 2 is closed; when the rolling member
33 rolls to a second position 3121F (as shown in Fig. 18) in the rolling groove 3121,
the locking block 32 moves out of the locking seat 31 to release the locking tongue
11, in which case the box body 2 is opened by the box cover 1.
[0041] Thus, by the fit among the rolling groove 3121, the sliding groove 321 and the rolling
member 33, the locking and unlocking of the locking block 32 may be achieved. Specifically,
referring to Figs. 16-20, when the rolling member 33 remains at the first position
3121E (as shown in Fig. 16), the locking block 32 is locked in the accommodating groove
3111, the lock catch mechanism 3 is locked with the locking tongue 11, and the box
cover 1 is at a state of closing the box body 2. When the box cover 1 is pushed backwards
to allow the rolling member 33 to move away from the first position 3121E, the locking
of the locking block 32 is relieved, and the rolling member 33 moves to the second
position 3121F (as shown in Fig. 18) under a pushing action of the tension spring
35, in which case the locking claw 322 completely releases the locking tongue 11.
In this case, the locking block 32 is locked at an extreme position outside of the
accommodating groove 3111, and the box body 2 is opened by the box cover 1.
[0042] Referring to Figs. 16-20, when the box cover 1 is pushed backwards again to allow
the rolling member 33 to move away from the second position 3121F, the locking of
the locking block 32 is relieved again. When the rolling member 33 moves to the first
position 3121E again, the locking block 32 is locked in the accommodating groove 3111
again, and the lock catch mechanism 3 is locked with the locking tongue 11 again.
If released, the box cover 1 may remain at the position where the box body 2 is closed.
As repeated in this way, the box cover 1 may achieve actions of opening and closing.
[0043] Specifically, referring to Fig. 16, the rolling groove 3121 includes a first groove
segment 3121A, a second groove segment 3121B, a third groove segment 3121C and a fourth
groove segment 3121D, which are connected in sequence end to end. The first groove
segment 3121A and the fourth groove segment 3121D intersect at the first position
3121E, the second groove segment 3121B and the third groove segment 3121C intersect
at the second position 3121F, the first groove segment 3121A and the second groove
segment 3121B intersect at a third position 3121G, and the third groove segment 3121C
and the fourth groove segment 3121D intersect at a fourth position 3121H. The rolling
member 33 is configured to roll unidirectionally and circularly in the rolling groove
3121 along a direction from the first groove segment 3121A to the second groove segment
3121B. That is, the rolling member 33 may roll circularly along a direction from the
first groove segment 3121A to the second groove segment 3121B to the third groove
segment 3121C to the fourth groove segment 3121D to the first groove segment 3121A
in sequence. In other words, the rolling member 33 may roll circularly along a direction
from the first position 3121E to the third position 3121G to the second position 3121F
to the fourth position 3121H to the first position 3121E.
[0044] The second position 3121F is located a side of the first position 3121E adjacent
to the box cover 1. For example, in an example shown in Fig. 16, the second position
3121F is located at a front side of the first position 3121E. The third position 3121G
and the fourth position 3121H are located at a side of the first position 3121E away
from the box cover 1. For example, in the example shown in Fig. 16, the third position
3121G and the fourth position 3121H are located at a rear side of the first position
3121E.
[0045] Referring to Figs. 15 and 16, since the rolling groove 3121 is located at the locking
seat 31 which is fixedly provided, and the sliding groove 321 is located at the locking
block 32 which is movably provided, when the rolling member 33 remains at the first
position 3121E, the locking block 32 is subject to a forward thrust exerted by the
tension spring 35, and has a tendency to drive the rolling member 33 to move forwards
through the sliding groove 321. However, since the rolling member 33 is also fitted
at the first position 3121E in the fixed rolling groove 3121, and the third position
3121G and the fourth position 3121H both adjacent to the first position 3121E are
disposed at the rear side of the first position 3121E, the rolling member 33 is stuck
at the first position 3121E and cannot move forwards. That is, the rolling member
33 is locked at the first position 3121E, and the locking block 32 is involved and
hence cannot move forwards either. Thus, the locking block 32 is locked at the current
position, i.e., the locking block 32 is locked in the accommodating groove 3111, so
as to lock the locking tongue 11 and thus allow the box cover 1 to be at a closed
position.
[0046] Referring to Fig. 15 and Figs. 16-18, when the rolling member 33 is pushed backwards,
for example when the box cover 1 is pushed backwards, the box cover 1 pushes the locking
block 32 backwards through the locking tongue 11 and the locking block 32 pushes the
rolling member 33 backwards through the sliding groove 321, the rolling member 33
may move backwards to the second groove segment 3121B where the third position 3121G
is (herein, the reason why the rolling member 33 at the first position 3121E does
not move to the fourth position 3121H will be described in the following), and thus
the rolling member 33 is unlocked. Then, under an action of the elastic force of the
tension spring 35, the tension spring 35 pushes the locking block 32 to move forwards,
and the locking block 32 drives the rolling member 33 to move forwards to the second
position 3121F (as shown in Fig. 18) through the sliding groove 321. In this case,
since the second position 3121F is located at a forefront end of the fixed rolling
groove 3121, the rolling member 33 cannot move forwards any more. Thus, the rolling
member 33 is locked at the second position 3121F, and the locking block 32 is involved
and hence cannot move forwards either. That is, the locking block 32 is locked at
the current position, i.e., the locking block 32 is locked outside of the accommodating
groove 3111, so as to release the locking tongue 11 and thus allow the box cover 1
be at an open position.
[0047] Referring to Figs. 15 and 18-20, when the rolling member 33 is pushed backwards again,
for example, when the box cover 1 is pushed backwards, the box cover 1 pushes the
locking block 32 backwards through the locking tongue 11 and the locking block 32
pushes the rolling member 33 backwards through the sliding groove 321, the rolling
member 33 may move backwards from the second position 3121F to the fourth position
3121H (herein, the reason why the rolling member 33 located at the second position
3121F does not move to the third position 3121G will be described in the following).
In this case, if the box cover 1 is released, the locking block 32 and the rolling
member 33 may move to the first position 3121E again (herein, the reason why the rolling
member 33 located at the fourth position 3121H does not move to the second position
3121F will be described in the following) under the action of the elastic force of
the tension spring 35, such that the rolling member 33 is locked at the first position
3121E again, the locking block 32 is also locked in the accommodating groove 3111,
the locking claw 322 locks the locking tongue 11 and the box body 2 is closed by the
box cover 1. As repeated in this way, the box cover 1 may be opened and closed alternately.
[0048] Referring to Figs. 15 and 22-24, the sliding groove 231 extends along the moving
direction of the locking block 32. For example, in the example shown in Fig. 15, the
locking block 32 moves along the front and rear direction, and the sliding groove
321 extends along the left and right direction. The sliding groove 321 is provided
with an elastic piece 34 (for example a metal elastic piece) therein, and in a direction
from the third position 3121G to the fourth position 3121H (for example a direction
from right to left shown in Fig. 15), a supporting surface 341 of the elastic piece
34 inclinedly extends towards the rolling groove 3121 (for example, upwards shown
in the Fig. 15). That is, in a direction from the fourth position 3121H to the third
position 3121G, the supporting surface 341 of the elastic piece 34 has a tendency
of extending downhill. The rolling member 33 is clamped between the supporting surface
341 of the elastic piece 34 and the rolling groove 3121.
[0049] Thus, referring to Figs. 15 and 16, when the rolling member 33 located at the first
position 3121E moves backwards, the rolling member 33 located on the elastic piece
34 in the sliding groove 321 tends to roll along a downhill direction of the elastic
piece 34 under an action of gravity. That is, the rolling member 33 has a tendency
to move towards the third position 3121G from left to right. Accordingly, this may
explain why the rolling member 33 located at the first position 3121E just moves towards
the third position 3121G, rather than the fourth position 3121H. Certainly, the present
disclosure is not limited to this, and other unidirectional position-limiting mechanisms
may be provided to ensure that the rolling member 33 may just move from the first
position 3121E to the third position 3121G unidirectionally.
[0050] Optionally, referring to Figs. 16 and 21, a first step surface 313 is provided between
the second groove segment 3121B and the third groove segment 3121C, and the first
step surface 313 extends inclinedly towards the locking block 32 (for example, downwards
shown in Fig. 21) along a direction from the second groove segment 3121B to the third
groove segment 3121C (for example, frontwards-leftwards shown in Fig. 21). The second
position 3121F is located at a side of the first step surface 313 adjacent to the
third groove segment 3121C. Thus, when the rolling member 33 locked at the second
position 3121F is subject to a backward thrust, since the rolling member 33 is pressed
tightly on a top portion of the supporting surface 341 and hence has no capability
of moving downwards to cross the first step surface 313, the rolling member 33 may
just roll and slide backwards and towards the fourth position 3121H along the smooth
third groove segment 3121C. Accordingly, this may explain why the rolling member 33
located at the second position 3121F just moves towards the fourth position 3121H,
rather than the third position 3121G. Certainly, the present disclosure is not limited
to this, and other unidirectional position-limiting mechanisms may be provided to
ensure that the rolling member 33 may just move from the second position 3121F to
the fourth position 3121H unidirectionally.
[0051] Optionally, referring to Figs. 16 and 21, a second step surface 314 is provided between
the third groove segment 3121C and the fourth groove segment 3121D, and the second
step surface 314 extends inclinedly towards the locking block 32 (for example, downwards
shown in Fig. 21) along a direction from the third groove segment 3121C to the fourth
groove segment 3121D (for example, backwards shown in Fig. 21). The fourth position
3121H is located at a side of the second step surface 314 adjacent to the fourth groove
segment 3121D. Thus, when the rolling member 33 locked at the fourth position 3121H
is subject to a forwards thrust, since the rolling member 33 is pressed tightly on
the top portion of the supporting surface 341 and hence has no capability of moving
downwards to cross the second step surface 314, the rolling member 33 may just roll
and slide forwards and towards the firth position 3121E along the smooth fourth groove
segment 3121D. Thus, this may explain why the rolling member 33 located at the fourth
position 3121H just moves towards the first position 3121E, rather than the second
position 3121F. Certainly, the present disclosure is not limited to this, and other
unidirectional position-limiting mechanisms may be provided to ensure that the rolling
member 33 may just move from the fourth position 3121H to the first position 3121E
unidirectionally.
[0052] Preferably, a position limiting groove 315 may be formed at the first position 3121E,
and the position limiting groove 315 is recessed in a direction running away from
the locking block 32. For example, in examples shown in Figs. 17-21, the position
limiting groove 315 is recessed upwards. When the rolling member 33 remains at the
first position 3121E, the rolling member 33 may be caught in the position limiting
groove 315, such that the position limiting groove 315 may ensure stability and reliability
of the rolling member 33 remaining at the first position 3121E, and further ensure
that the box cover 1 may steadily remain at the position where the box body 2 is closed.
[0053] Referring to Figs. 1-24, an action process of opening and closing of the filter box
assembly 200 according to embodiments of the present disclosure will be briefly described
in the following.
[0054] Referring to Figs. 1 and 3, when the washing machine is used normally, the box cover
1 is at the position where the box body 2 is closed. In this case, the locking block
32 shown in Fig. 15 is located in the accommodating groove 3111, the two locking claws
322 of the locking block 32 clasp the neck portion 111 of the locking tongue 11 shown
in Fig. 8, the rolling member 33 remains at the first position 3121E in the rolling
groove 3121 shown in Fig. 16, and the tension spring 35 is at the compressed state.
[0055] When the box cover 1 needs to be opened, the box cover 1 may be pushed backwards,
then the box cover 1 drives the locking tongue 11 to push the locking block 32 backwards,
and the locking block 32 pushes the rolling member 33 to move backwards through the
sliding groove 321, such that the rolling member 33 may slide towards the third position
3121G along the first groove segment 3121A and the downhill direction of the supporting
surface 341. When the rolling member 33 moves to the second groove segment 3121B where
the third position 3121G is, the backward thrust exerted on the box cover 1 is withdrawn,
and under the action of the elastic force of the tension spring 35 recovering its
original shape, the tension spring 35 pushes the locking block 32 to move forwards.
During the forward movement of the locking block 32, through the sliding groove 321,
the locking block 32 drives the rolling member 33 to move to the second position 3121F
in the rolling groove 3121 and stop thereat. In this case, the locking claw 322 completely
moves out of the accommodating groove 3111 to release the locking tongue 11. Under
an action of an inertia force of the locking tongue 11 which is pushed to move forwards,
the box cover 1 may continue moving forwards. Preferably, the box cover 1 may slide
along an arc guide rail 5 shown in Fig. 5, so as to open the box body 2 completely.
[0056] When the box cover 1 needs to be closed, the box cover 1 may be pushed backwards
again, the box cover 1 drives the locking tongue 11 to push the locking block 32 backwards,
and the locking block 32 pushes the rolling member 33 to move backwards through the
sliding groove 321, such that the rolling member 33 may slide from the second position
3121F to the fourth position 3121H along the third groove segment 3121C. When the
rolling member 33 moves to the fourth groove segment 3121D where the fourth position
3121H is, the backward thrust exerted on the box cover 1 is withdrawn, and under the
action of the elastic force of the tension spring 35 recovering its original shape,
the tension spring 35 pushes the locking block 32 to move forwards. During the forward
movement of the locking block 32, through the sliding groove 321, the locking block
32 drives the rolling member 33 to move towards the first position 3121E along the
fourth groove segment 3121D and stop in the position limiting groove 315 at the first
position 3121E. In this case, the locking claw 322 is retracted in the accommodating
groove 3111 to lock the locking tongue 11 and hence the box body 2 is closed by the
box cover 1. As repeated in this way, the opening and closing of the box cover 1 may
be achieved.
